RELATED FIELD

[002] The present invention relates to an improved tool and methods of use of said tool, including use with an ophthalmic lens or lens blank during deblocking.

BACKGROUND

[003] The fabrication of a lens, such as an ophthalmic lens, includes processing steps in order to form suitable front and back faces of the lens, said processing steps generally impart one or more specific optical properties to the lens, and may alter the lens about its periphery. The latter process is called edging. Edging a lens to obtain a desired shape involves a series of steps. Typically, when edging a lens, the optical center is located and marked; the marking is generally made on one of the front or back faces of the lens.

[004] Next, the lens is attached to a lens block by a holding mechanism, so that at least horizontal axis, of the lens is aligned with the center point of the block, also referred to as an edging block. A desired peripheral shape is then imparted to the lens.

[005] Some means must be provided in order to attach the lens blank to the edging block with a bond (in the ophthalmic industry this is typically a thin rubber pad with adhesive properties on both sides) that assists in stabilizing the lens during alteration, yet is possible to break one the alteration is complete. In practice, the lens may be removed from the block by a variety of methods. For example, the lens may be pried from the block. However, this method has the disadvantage that the lens is often chipped, scratched, or otherwise damaged by the act of prying. The lens removal may also be facilitated by immersing the lens and block in hot water for a short period of time. However, some plastic lens materials (or one or more coatings applied thereon) cannot withstand such temperatures. Removal may also be accomplished by placing the combination of the lens, the blocking pad and the block into a cavity of a mounting block and then rotating the lens and the block in opposite directions with respect to each other, thereby causing them to separate. This may cause crazing of the lens.

[006] For the edging process, itself, a button (also referred to as a blank or precursor) is attached to the lens that enables the edging machine to cut the lens to shape, or to form the peripheral shape. After this process is complete, to remove the button or the block, the button is placed in a circular groove of the head of the deblocking tool, and a handle is pressed to squeeze the button off of the lens. An operator may use a handheld deblocking tool to remove a block (or button) from the lens. One example of a handheld tool is a deblocking plier, such as one from Western Optical Supply, Inc. Unfortunately, current handheld tools may also lead to crazing of the lens.

[007] Crazing, which appears like a network of fine cracks on the surface of a material, is a phenomenon that frequently precedes fracture. Crazing occurs in regions of high hydrostatic tension, or in regions of localized yielding, and generally leads to the formation of interpenetrating microvoids and small fibrils. Applied tensile loads will propagate the craze, which may eventually lead to larger microvoids, weakening the lens. As microvoids coalesce, cracks will begin to form. Lenses that are damaged by such defects are no longer suitable and have to be discarded, thereby increasing manufacturing costs.

[008] Current handheld deblocking tools have other disadvantages in addition to causing crazing. Their design may cause other surface defects. In addition, user repetition in removing the lenses can further damage the lens. It can be difficult to perform the lens removal operation rapidly while avoiding damage to a top coating of the lens. On average, during an eight hour shift, an operator can perform up to about 500 twists of a deblocking tool per lens per day. Existing deblocking tools require an operator to repeatedly rotate or twist their wrists to remove a block from the lens. This tool can present repetitive use problems and injuries. After a period of time in such an occupation, the operator is likely to suffer various forms of fatigue and injury including, for example, carpal tunnel syndrome or other types of repetitive strain injury. This repetitive motion can also cause a user to revert to an aggressive removal or "twist and fly-away" motion of a block after prolonged application of this process, instead of a clean break. This twist and fly-away motion adds pressure to the lens upon removal, which should be avoided, or can otherwise scar or pit the lens surface. It also can cause crazing to the lens's coating, as described above.

[009] Accordingly, problems arise with any of said conventional methods of lens deblocking as described above, as said methods will result in crazing, pitting and/or other scarring and damage to the lens, or may require additional treatment steps to remove adhesive residue from the lens.

[0010] Thus, there remains a need for a deblocking tool that addresses one or more of the above identified problems.

[0011] The deblocking tool disclosed herein solves problems disclosed above.

SUMMARY

[0012] In one or more forms is an apparatus for deblocking a lens comprising a body extending along a central axis. The body comprises a proximal end and a distal end. The proximal end comprises at least one gripping member. A sleeve may be positioned about the central axis of the body. The sleeve is operably connected to the distal end of the body. The sleeve may surround at least a portion of the body. A translatable member is operably connected with the sleeve, and in some embodiments, forming a part of the body. A functional insert is slideably positioned within the sleeve, operable with the translatable member, such that the translatable member provides motion to the functional insert.

[0013] The described apparatus provides an improvement in hand-held deblocking tools. For example, the disclosed deblocking apparatus reduces damage to a fragile top coating of a lens that may be caused by an operator's usage of current handheld tools. The disclosed deblocking apparatus may also reduce the chance of user injury. The deblocking apparatus, with its improved design is capable of attaching to at least a portion of a button, such as a button attached to a lens. The deblocking apparatus helps reduce the amount of force needed by a user to twist and remove a button from a blocked lens, reducing user error, the chance of user injury, and the chance of damage or crazing of the lens, thereby saving time, and decreasing manufacturing costs and decreasing loss in manufacturing that occurs with alternative hand-held deblocking tools.

[0014] In one or more embodiments is a device. The device may be used in any of a number of applications. In one application, the device is for deblocking a lens. The device comprises a body having a central axis along its length. The body further comprises a proximal portion and a distal portion. The proximal portion comprises opposing gripping members of a curvilinear or ergonomic shape. The distal portion comprising a head section positioned about the central axis, the head section including a sleeve region having one end with an opening and a cavity formed therein. The cavity is configured for one or more of removably receiving at least one functional insert, and slideably moving at least one functional insert therein. The proximal portion of the head section is configured for receiving a moveable and/or rotatable member. The device further comprises a moveable member having a proximal end and a distal end and one or more grooves in a helical configuration on an outer surface. The moveable member is generally positioned along the central axis of the body. The moveable member may be operably coupled with the sleeve region for translating within the cavity. The sleeve region may be further configured for joining with gripping members. The sleeve region may have a frustoconical shape at least at one end with an inner surface for receiving a functional insert. The proximal portion may include a stop member positioned along the central axis for joining with said opposing gripping members and for coupling with a moveable member. The device may further comprise a spring member positioned along the central axis for maintaining the opposing gripping members in an unbiased and open state.

[0015] In further embodiments is an apparatus. The apparatus may be used in any of a number of applications. In one application, the apparatus is for deblocking a lens. The apparatus comprises a body having a central axis along its length. The body further comprises a proximal portion and a distal portion. The proximal portion includes opposing gripping members. The distal portion includes a head section positioned about the central axis. The head section includes a sleeve region having one end with an opening and a cavity formed therein. The apparatus further comprises a functional insert operably associated with the head section for moveable action between a first position and a second position. The first position will include at least a portion of the functional insert within the cavity. The second position will include at least a portion of the functional insert extending away from the cavity. The functional insert is generally comprised of at least two components that retract when the functional insert is in the second position. The functional insert translates from the first position to the second position by a moveable member operably coupled to one end of the functional insert. The one end of the functional insert penetrates through an insertion hole in the head section at an end opposing the one end of the sleeve region where the cavity is contained. The functional insert is configured for any one of rotation when translating from the first position to the second position, expansion when in the second position through a plurality of mateable components, or permanent positioning within the head section. The functional insert includes gripping regions for gripping and rotating at least a portion of a button. The gripping members are operably coupled to the head section. The head section is operably coupled with one or more of a rotational guide member and a spring member.

[0016] Also described is use of an apparatus for deblocking a lens or lens blank, the apparatus comprising a body having a central axis. The body further comprises a proximal portion and a distal portion. The proximal portion includes opposing gripping members. The distal portion includes a head section positioned about the central axis. The head section includes a sleeve region having one end with an opening and a cavity formed therein. With use of the apparatus, the apparatus will further comprise a functional insert operably associated with the head section for moveable action between a first position and a second position. The first position will include at least a portion of the functional insert within the cavity. The second position will include at least a portion of the functional insert extending away from the cavity. The functional insert comprises at least two components that retract around at least a portion of an article associated with the lens or the lens blank when the functional insert moves from the first position to the second position.

DETAILED DESCRIPTION [0031] The words or terms used herein have their plain, ordinary meaning in the field of this disclosure, except to the extent explicitly and clearly defined in this disclosure or unless the specific context otherwise requires a different meaning.

[0032] If there is any conflict in the usages of a word or term in this disclosure and one or more patent(s) or other documents that may be incorporated by reference, the definitions that are consistent with this specification should be adopted.

[0033] The indefinite articles "a" or "an" mean one or more than one of the component, part, or step that the article introduces.

[0034] Whenever a numerical range of degree or measurement with a lower limit and an upper limit is disclosed, any number and any range falling within the range is also intended to be specifically disclosed. For example, every range of values (in the form "from a to b," or "from about a to about b," or "from about a to b," "from approximately a to b," and any similar expressions, where "a" and "b" represent numerical values of degree or measurement) is to be understood to set forth every number and range encompassed within the broader range of values, and including the values "a" and "b" themselves.

[0035] Terms such as "first," "second," "third," etc. may be assigned arbitrarily and are merely intended to differentiate between two or more components, parts, or steps that are otherwise similar or corresponding in nature, structure, function, or action. For example, the words "first" and "second" serve no other purpose and are not part of the name or description of the following name or descriptive terms. The mere use of the term "first" does not require that there be any "second" similar or corresponding component, part, or step. Similarly, the mere use of the word "second" does not require that there be any "first" or "third" similar or corresponding component, part, or step. Further, it is to be understood that the mere use of the term "first" does not require that the element or step be the very first in any sequence, but merely that it is at least one of the elements or steps. Similarly, the mere use of the terms "first" and "second" does not necessarily require any sequence. Accordingly, the mere use of such terms does not exclude intervening elements or steps between the "first" and "second" elements or steps, etc.

[0036] Herein, the term "lens" means an organic or inorganic lens, preferably an organic lens comprising a lens substrate which may be coated with one or more coatings of various natures. As used herein, "lens blank" means a transparent medium of a known base curve, with no power, used by optical laboratories, to generate a finished spectacle lens with prescribed powers; it is used for single vision, bi- and tri-focals, and progressive additional lenses (PALs).

[0037] As used herein, "proximal" means closest to a user, and "distal" means farthest from the user.

[0038] Referring to FIGS. 1-3, representative embodiments are illustrated. Said embodiment provide a device 37 having a body extending along a central axis generally comprising at least a proximal portion 3, and a distal portion 5.

[0039] A head section 25 is positioned distally, at or near a distal portion 5 of the tool 37. The head section 25 may have an outer feature that is smooth, is ridged or some variation thereof. A close-up view of an outer feature of head section 25 that is ridged is illustrated in FIG. 3. In some embodiments, head section 25 presents with an overall or peripheral geometry may be curvilinear, such that, on cross section, there is a single central axis and a same radius extending outwardly from the central axis, thereby providing a generally uniform center when viewed in cross-section. In some embodiments, the radius, r, is not uniform from a uniform center, thereby forming a non-uniform geometry (outer shape in cross- section), said shapes comprising any of a polygon, ellipse, and variations thereof. In some embodiments at least some or all of the outer or periphery of head section 25 forms a cylindrical shape, which may include, for example, a generally circular cylinder (as depicted in FIG. 1), an elliptical cylinder, and a polyhedra. In some embodiments, the cylindrical shape in cross-section change from a first end 26 to a second end 27. Non-limiting examples include a cone shape (as depicted in FIGS. 2, 3), a double cone shape (e.g., stacked cones, or hour-glass shape), or part cone and part cylinder shape (as depicted in FIGS. 1 and 4). Said shapes in cross-section may have a uniform center or be oblique.

[0040] The device 37 also comprises a handle section having opposed first and second gripping members 9; the gripping members are moveable and generally positioned and configured in a manner in which the members when translated share a same plane. At least a portion of the handle section is positioned proximally, at or associated with proximal portion 3 of the device 37. Gripping members 9 may have a least another portion of the handle section positioned distally, at or associated with a distal portion 5 of the device 37. Generally, one end of gipping members 9 is associated with head section 25, as depicted in FIGS. 1, 2, and 4. In some embodiments, a second end of gripping members 9 is associated with a stop means 11 , as depicted in FIG. 4. Each gripping member comprises an outer surface or region 10, an inner surface or region 53, and a more proximal portion or end region 43. The gripping member may be continuous with said regions or said regions may comprise joints, hinges and/or separable parts, in which separable parts may include one or more parts that have been fixedly secured together with or without additional joints or hinges, some or all of which may be removably secured and may be replaceable. In some embodiments, there is a moveable joint 44 coupling two of said regions as depicted in FIG. 4. In FIG. 4 a pin-type joint, or a knuckle -type joint with a tongue and groove is shown. Said moveable joint as shown includes a single eye associated with one of said regions at its mating end, a double eye associated with another of said regions at the complementary mating end, and a pin for passing through the single and the double eyes. Joints may also be formed of alternative configurations, such as but not limited to a turnbuckle-type joint, ball joint, ball bearing, rolling joint, heim joint, saddle joint, pivot joint, hinge joint, gliding joint, which may be used alone or in combination. Movement by the moveable joint 44 may be in one plane alone or may comprise more than one plane. In some embodiments, when movement of said moveable joint occurs in more than one plane, said movement in the one or more planes may be limited in part by the surface configuration of the region, such as surfaces near or neighboring said moveable joint 44 and/or by the moveable joint itself. For example, a step or lip 18 may be formed as part of the outer surface configuration, as depicted in FIG. 4, limiting rotation about said joint by the surface gradation. Movement of the moveable joint 44 is often limited in part by stop member 11, as depicted in FIG. 4. The position of stop member 11 as depicted in FIG. 4 assists, in part, in preventing gripping members from contacting each other. Gripping members are generally designed such that the proximal portion or end region 43 of each gripping member do not contact one another. Contact is prevented, in part, by the presence of one or more of the stop member 11, a tension bar 13, and/or the general shape of said gipping members 9 in combination with other features described herein, including tension member 19 and/or head section 25. The shape of gripping members 9 are not limited to shapes illustrated in the accompanying drawings. Alternative shapes, including ergonomic shapes are readily contemplated and suitable for use with the described device 37.

[0041] In some embodiments, the gripping members 9 may further comprise a hollow cavity 15.

In many of said embodiments, along inner surface or regions 53 or within hollow cavity 15 there is receipt of a tension member 19 as depicted in FIG. 1. The tension member 19 may in these embodiments be spring-loaded. Alternately, tension member 19 may comprise or include alone or in combination a wire, string, thin cable, chain, spring, truss, and/or other components that experience a tensile and/or compressive force, and/or rotational force (torque). Tension member 19 will generally be associated with both gripping members 9, as depicted in FIGS. 1, 2, 4-8 either directly or indirectly. Said tension member 19 is often pre-loaded. Pre-loading causes the gipping members 9 to prefer a first or unbiased configuration. Associated with each tension member 19 may be a guide member 17, with or without additional fillers, and/or grooves. The guide member 17 may surround tension member 19, as depicted in FIG. 1, or guide member 17 may be surrounded by tension member 19, as depicted in FIG. 4. In some embodiments, a tension member 19 is positioned along a central axis as depicted in FIGS. 2 and 4. Tension member 19 is fixedly secured at or near at least one end region (e.g., at or near end region 19a on FIGS. 1 and 4), or may be fixedly secured at or near both end regions (e.g., at or near end regions 19a and 19b of FIG. 4). Securement may, in some embodiments, be releasable or removable. Securement may be permanent (e.g., by weldment, soldering, and/or adhesive). Tension member 19 is generally coupled with, directly or indirectly, or associated with head section 25. For example, tension member 19 at or near its end region 19a may be coupled with head section 25 on an interior surface region bounded by opening 54 forming an insertion hole of the head section 25 having sidewalls 59 (see, e.g., FIG. 8), or said end region 19a of tension member 19 may be coupled to, bounded by, or associated with a surface region of second end 27 of head section 25. In some embodiments, tension member 19, while coupled, may comprise a moveable distal end 19a (e.g., FIG. 1). End region 19b may be similarly associated with or may be secured by stop means 11 (see, e.g., FIGS. 1 and 4). In FIG. 1, proximal end 19b of tension member 19 is secured or held firmly in place by the stop means 11, either through a region in its interior or with end region 32. In some embodiments, stop means 11 is, for example, a soft or hard metal anchor or plug. Securement between tension member 19 and stop means 11 may be permanent, for example, by soldering, or may be removable. In some embodiment, the tension member may be unsecured at its ends but will in generally be bounded, such as by a shaft. For example, tension member 19 in FIG. 4 may or may not be secured at its end but is positioned or bounded by guide member 17.

[0042] The gripping members 9 may be comprised of stainless steel. The gripping members 9 may be also be comprised of a metal other than stainless steel or a metal alloy or ceramic or composite material as long as it is a material with sufficient strength and rigidity for gripping and for motions as are further described herein. Gripping members 9 may be coated or further surfaced or abraded or molded or shaped, such as in a manner to promote gripping by a hand, as desired. Features to enhance gripping may also include additional moldings and/or paddings or other insulation. Said features may be affixed, applied to or otherwise thereon. Any of said enhanced gripping features may be applied to any of or portion of the outer surface region 10, and/or inner surface region 53 and/or end region 43 as needed. In some embodiments, at least a portion of the outer surface 10 of the gripping members 9, which may also include a portion of end region 43, may be surrounded by one or more of padding or other insulation. The outer surface of the gripping members 9 and/or a portion of said padding or insulation may also or alternatively have a ridged or grooved or raised or stippled or other desired pattern to facilitate gripping by a user.

[0043] Each gripping member may be independently moveable about a single or a common axis, as illustrated in FIGS. 1 and 2. Or gripping member may be independently moveable with movements comprising differing axes, as illustrated in FIGS. 4-8. Gripping members 9 are moveable in a region or an intersection with head section 25. Movement may include a single joint, as depicted in FIGS. 1 and 2, or two independent joints, depicted in FIGS. 4-8. Movement about said joint may be through a pivoting means, as depicted in FIG. 1, a threaded means, as depicted in FIG. 2, or a hinge means as depicted in FIGS. 4-8. Additional means that comprise any one or more of the previously described joints associated with moveable joint 44 may also be suitable. Said moveable joint 44 when included assist in providing movement and translation of gripping members 9 between a first (unbiased) and a second (biased) state. In addition, other moveable means may also be used, or in some combination thereof, or in replacement of those depicted in the drawings, such as a spring mechanism, bearing members or alternative hinge joint. One representative configuration includes a bore hole 52 that extends at least partially through and near an end region of the gripping members 9 through which the pivot pin 51 enters and/or exits (see, FIGS. 1, 5). Said pin 51 joins the gripping member 9 at or near said end region and with head section 25. The pivot pin 51 may comprise a cylindrically shaped pivot-pin head and a base part. Usually the pivot- pin head is positioned on one side of the bore hole, while the base part of the pivot pin is positioned on the other end of the bore hole. The pivot-pin head and/or the pivot-pin base part may or may not extend outward from the periphery of the head section. The head section may include a recessed region 52 which allows the pivot-pin head and/or the pivot-pin base part to reside within, allowing the pivot-pin head and/or the pivot-pin base part to be partially hidden or to prevent any portion of the pivot-pin head and/or the pivot-pin base to extend outwardly from the periphery of the head section. A screw or some other connecting means may connect the head of the pivot pin to the base part of the pivot pin 51.

[0044] At rest, the gripping members 9 are positioned in an unbiased or open state, as illustrated in FIGS. 1, 2, and 4. Upon application of a force or pressure to at least one of the gripping members, such as by a user applying a force to one or each of the gripping members that moves at least one of the gripping members 9 towards the central axis or towards each other, the gripping members 9 may be moved to a second or biased state, which differs from the open state. An example of gripping members in a biased or second state is depicted in FIG. 6.

[0045] Gripping members may be maintained when in rest in their unbiased state (open position) in part via one or more tension member 19, tension member 19 having a first and preferred shape or configuration in tension. A second shape or configuration of said tension member(s) 19, when in compression, is not its preferred shape or configuration.

[0046] In some embodiments, gripping members 19 remain in the open position in part by addition of tension bar 13, one end of which is positioned on the inner facing surface 53 or within hollow cavity 15 of device 37 (see FIG. 1). Tension bar 13 may also be in the form of a return spring. Tension bar 13 assists with simultaneous opposite movements of the gripping members 9, while preventing overlapping or cross-over of the gripping members 9. In some embodiments (not shown), the device 37 may have two tension bars 13. With two tension bars, a second tension bar 13 is positioned on the inner surface 53 of the opposing gripping member 9 such that the free distal ends 13a of each tension bar 13 come in contact and become temporarily joined together (in a space formed between the gripping members 9) to form a wishbone -like shape.

[0047] The tension bar 13, such as depicted in FIG. 1, may have an arcuate shape that extends outwardly from the inner surface 53 (or outwardly from the hollow cavity 15). Alternative shapes are also acceptable. Generally, such a tension bar 13 will be positioned in or within a same plane as at least a portion of the gripping members 9. The tension bar 13 may not, in some embodiments, have a same thickness or width as the thickness or width of a gripping member 9. A proximal end 13b of the tension bar 13 may be secured, bonded or otherwise fitted to the inner surface 53 or the hollow cavity 15 of the gripping member 9 to ensure a stable attachment; the fitting is in a region between head section 25 and end region 43 or may be closer to end region 43. The securement may be permanent, such as by weldment, soldering, or other secure bonding. The proximal end 13b of tension bar 13 may also be fitted by a secure but removable fixation, such as by a lock-fit, screw fit, pin-fit, or other means known and useful for removable fixation. In one or more embodiments, from the proximal end 13b, the tension bar 13 is outwardly curved to a free distal end 13a of the tension bar. The tension bar 13 may have sufficient flexibility to allow the gripping members 9 to be moved toward each other while initially having one of the gripping members in contact with the free distal end 13a of the tension bar 13, but it will have enough rigidity to then function as a stop that prevents gripping members from contacting each other or from associating a close proximity to each other. In operation, the tension bar, when in contact with an opposing gripping member 9, will urge said gripping member and device 37 to revert to its open or unbiased state. Whereas each gripping member 9 will generally have a same length and width or thickness, the tension bar 13 generally has a width and length that is equal to or less than the width and length of the gripping members 9. The tension bar 13 allows the gripping members 9 of the device 37 to remain in the open position as the handle section is left in the unbiased state.

[0048] Referring back to tension member 19 and with reference to FIG. 4, said tension member

19 is secured at end region 19b by stop member 11 and to head section 25 by opposing end region 19a. Here, tension member 19 is centrally positioned between gripping members 9 and may comprise, for example, a compression spring or a ribbon spring. It may also comprise one or a plurality of bendable strips of metal, so shaped to rebound when compressed. Tension member 19 may further comprise one or more notched regions releasable from a recessed region in head section 25 and positioned along its length (not shown). Tension member 19 is provided in or within a same plane as at least a portion of the gripping members 9. End region 19b of the tension member 19 may be secured, bonded or otherwise fitted to stop member 11, in which the securement will ensure a stable attachment. The fitting or securement may be permanent, such as by weldment, soldering, or other secure adhesion or bonding, or by other secure (and/or releasable) fittings, including but not limited to a lock-fit, screw fit, or pin-fit. The tension member 19 will have sufficient tension to maintain the gripping members 9 in their open configuration with enough resilience to allow movement or translation of the gripping members 9 toward each other (see FIG. 6). In operation, the tension member 19 will urge said gripping member and device 37 to revert to its open or unbiased state.

[0049] Referring again to head section 25, the head section may include a sleeve region 21a and proximal portion 21b. Said region 21a and portion 21b may be separable pieces or of a single molded piece. Similarly, said region 21a and portion 21b may have a same or differing peripheral shapes. For example, each region or portion may further comprise more than one geometry along its periphery. For example, the sleeve region may have an outer geometry that is conical, e.g., frustoconical, as depicted in FIGS. 1 and 3, or cylindrical, as depicted in FIGS. 4-8. Alternative shapes are also acceptable, such as polygonal. Sleeve region 21a and proximal portion 21b may comprise the same material or different materials. Suitable materials include but are not limited to a high strength plastic, stainless steel, ceramic, or metal alloy, as examples. Said material selection may be the same as or different from the handle section. The material will be able to withstand a torque placed upon the head section during a deblocking operation. Sleeve region 21a may be integrally formed with proximal portion 21b, or securely fitted with proximal portion 21b. In combination they form and define an open cavity 22 that is substantially bounded or bounded in part by an endmost region 27 of proximal portion 21b while open at the endmost region of the distal end 26 of sleeve region 21a. In some embodiments, it is the proximal portion 21b that is attached or operably coupled with the handle section of the device 37 by way of seam line 41 as depicted in FIG. 1, which may not be represented to scale. In some embodiments, it is the sleeve portion 21a that is attached or operably coupled with the handle section of the device 37 by way of insets 42 as depicted in FIG. 8 that may or may not be held by hinge configuration through eyes 64 as depicted in FIG. 4, which may include or be replaced by additional coupling means or linkages for providing a moveable joint, such as a pin and collar (not shown), or ball and socket (not shown), reversible screw and threading (not shown), slip or gliding joint, etc. Said coupling of the sleeve portion 21a and handle section of the device 37 may also be provided by any of the type or combination of types of moveable joints described previously. The open cavity 22 of head section 25 is capable of receiving at least a portion of at least one functional insert 39.

[0050] The functional insert 39 is considered slideable with respect to head section 25. In some embodiments, the functional insert 39 is slideably inserted into and removably coupled within head section 25. Alternatively, functional insert 39 may be more permanently secured within head section 25. The insertion of and/or fixed positioning of the functional insert 39 is by way of cavity 22, through sleeve region 21a. Slideable movement between the functional insert and the head section will include an outer surface of the functional insert 39 slideable along or against at least a portion of the inner surface of the open cavity 22, providing movement (linear and/rotational) of the functional insert with respect to the head section 25. Movement may include contact along slideable regions that include interior surfaces of the cavity 22 and side surfaces of the functional insert 39. Movement may comprise no direct contact between said slideable regions.

[0051] Any desired functional insert 39 may be positioned and/or inserted into cavity 22 and be slideable with and/or removably releasable within head section 25 of the device 37, based on a user's preference or the required operation of device 37. The functional insert 39 is not secured with head section 25, rather securement includes at least the one or more tension member 19 (FIGS. 1-3), or guide member 17 (FIGS. 4, 8). Accordingly, the head section may remain stationary while the functional insert translates within head section and while the handle sections translate towards the head section. Securement and, therefore, motion of the functional insert is by way of a moveable or translatable member, in the form of any one or more of at least one tension member 19 and/or at least one guide member 17. When the functional insert is removable, it may be accompanied by an audible and/or tactile mechanism to ensure proper coupling (not shown). The functional insert 39 may also be manufactured to be permanently attached to the device 37 as just described. The functional insert 39 may be made, for example, of a polytetrafluorethylene (PTFE) compound or material formed from PTFE (e.g., Teflon, registered with E.I. Du Pont de Nemours and Co., Delaware, USA), or may include a PTFE or similar type material as an outer coating. Other materials that are wear-resistant and tough are also suitable for use.

[0052] In some embodiments, the functional insert 39 may comprise more than one component

45. Said more than one component 45 will be moveable as a unit. The unit will traverse between the proximal and distal portions of cavity 22 in a linear motion and/or rotational motion, in which rotation, as depicted by arrow 40 in FIGS. 1, 2, 7, may be clockwise or counterclockwise. With linear and/or rotational motion via the moveable member described above, the moveable unit comprising the functional insert 39 will traverse outwardly from within cavity 22 or will traverse inwardly into cavity 22. Movement outwardly is accompanied by an expansion of the functional insert at its distal region as the more than one component 45 move away from each other. Expansion is generally in a manner as depicted by arrows 55 in FIG. 6. Movement inwardly is accompanied by a retraction of the previously expanded more than one component 45. In an unbiased state of the device 37, when gripping members 9 are open, the functional insert 39 is held within cavity 22, and the more than one component 45 are in their retracted state. This is depicted generally in FIGS. 1, 2, 4, and 7. In a biased state of the device 37, when gripping members 9 have translated towards one another, at least a portion of the functional insert extends outwardly from cavity 22, as is generally illustrated in FIGS. 3 and 6. When a sufficient portion of the functional insert 39 is extended outwardly, the more than one component 45 will expand, moving away from each other (or further away from each other when already spaced apart, as is depicted in FIGS. 1 and 2). Said expansion may be unassisted, or it may be assisted by a biasing member positioned between the more than one components 45. The biasing member will generally be positioned on or near side edges between two components 45. The biasing member may be an element that is preloaded in tension; however, said load may not exceed the preload associated with tension member 19. The biasing member may be freely held or retained in a recess. For a more stable positioning, the biasing member may be bounded at its ends (or on at least one end) by a boundary wall. The biasing member may also be contained on a shaft. In any such configuration, the biasing member may be fixedly or removably secured at one or both ends. In some embodiments, a biasing member (not shown) may maintain the components 45 in a more spaced apart configuration, such that a space 70 is present between at least portions of the components 45, even when said components 45 are retracted inwardly, as is represented in FIGS. 1 and 2. Said space 70 may also be provided when components 45 are so shaped, which includes non linear portions that prevent components from forming a complete and complementary mating along at least its side edges, as is represented in FIGS. 1 and 2.

[0053] With respect to the functional insert 39, the linear and/or rotational motion of the functional insert 39 from an outward position (at least partly extending away from cavity 22 of head section 25) to an inward position (within cavity 22 of head section 25) translates the functional insert from an unbiased state to a single retracted, more biased state. Movement of the functional insert 39 from its expanded (biased) state to its retracted (unbiased) state requires movement of the handle section, such as by a user or a robot, in which gripping members 9 are forced from the unbiased (open) position to the biased (closed) position. Said movement is directly and operably associated with movement of the moveable member as described above. With rotation of the moveable member, depending in part on the pitch of the turns that provide the rotation and on the amount of expansion required for the more than one component 45, the functional insert 39 may rotate only a only a few degrees or up to about 180 degrees of rotation, or, in some instances, more than 180 degrees, and in any rotations range or amount therein. Similarly, with a linear movement of the moveable member, and hence, linear translation of the functional insert 39 (with or without concomitant rotational motion), the extent of release of the functional insert 39 from within the cavity 22, as the functional insert 39 is extended away and outwardly from the cavity 22, may be only a small fraction of the length of the functional insert, or may comprise up to or more than half the length of the functional insert. Assistance in expansion of the functional insert 39 may be provided by the shape of interior cavity 22 of the head section. A conical shaped head section that increases in its cross section diameter when moving from region 21b to sleeve region 21a as illustrated in the drawings.

[0054] To facilitate uniform movement of the functional insert, force is applied simultaneously to each of the gripping members 9. This is facilitated when gripping members 9 are each of a similar configuration, including a similar length, width, and with similar or the same material(s) used to construct said gripping members. Said uniform construction may not be essential for use of the device 37 in certain applications. The applied force on the gripping members 9 causes an inward translation of the forced gripping member towards the central axis, which, by way of an operable coupling with the moveable member (e.g., tension member 19 and/or guide member 17), displaces the functional insert 39 from its biased or first position. The displacement of functional insert 39 may be facilitated by a compression of the tension member 19 (e.g., FIG. 4), by a translation of the tension member 19 (e.g., FIGS. 1 and 2), and/or by a translation of the guide member 17 (e.g., FIGS. 4 and 6). Pressure applied via the moveable (translatable) member through the proximal end 46 of the functional insert 39 displaces the functional insert 39 so that it moves from its more biased position (inward and retracted position, and, thus, generally within cavity 22) to a less biased or to a fully unbiased position, in which the functional insert is extended outwardly from cavity 22 (either partially extended or fully extended, respectfully). In some embodiments, the functional insert 39 in its first or biased position is completely within cavity 22, hence when it is retracted. In some embodiments, only a portion of the functional insert 39 is completely within cavity 22, even when in its retracted position, such that even when retracted at least a portion of the distal end of the functional insert 39 extends outwardly from cavity 22. In some embodiments, a face 29 of the functional insert 39 may be even with or flush with the distal most end of the distal portion 21a of the head section 25. In some embodiments, up to 50% of the functional insert may extend beyond the distal end of the sleeve 21a when the functional insert 39 is displaced from the inward (retracted) position to the outward (extended) position. In some embodiments, more than 50% of the functional insert may extend beyond the distal end of the sleeve 21a when the functional insert 39 is displaced from the inward (retracted) position to the outward (extended) position.

[0055] The functional insert 39 may have a cross-sectional diameter at its proximal end 46 that is smaller than the cross-sectional diameter at its more distal end, as is depicted in the drawings. Whether or not the cross-sectional diameter of the functional insert differs along its length, the total cross-sectional diameter of the functional insert will, when expended, be greater than the cross-sectional diameter at that same location when the functional insert is in its retracted state.

[0056] In one embodiment, the functional insert 39 may be a block clamp in the shape of a

"fluted" or flowering insert (see, e.g., FIGS. 1 and 2). It may be removably inserted within cavity 22. When in the expanded or less biased position, the functional insert 39 present with its fluted or flowering configuration. The functional insert may also be in the form of a cup or cup-like in shape having the same inner and outer geometry (not shown), or having an outer geometry that differs from its inner geometry 34, as depicted in FIG. 7. At least a portion of the inner geometry 34 of the functional insert 39 provides a gripping surface for receipt of an article. The article may be a button or a block, such as for deblocking of a lens or lens blank. The article may be any article that needs to be repositioned and/or removed from its location. There is no limit to the type or shape of the article as long as at least a portion of said article may be suitably contacted (gripped) by the gripping surface(s) of the interior 34 of the functional insert 39. The gripping surface(s) of the functional insert may be the same and hence, of a complementary shape as the article to which it will grip. The gripping surface(s) of the functional insert 39 may also differ from that of the shape of the article to which it will grip, as long as at least a portion of the article is suitably gripped in order to be repositioned and/or removed from its location. In the unexpanded position, the more than one components 45 (and generally at least two components 45) are retracted, which may include contact between portions of the components 45, such as along seams 56. Seams 56 may or may not be continuous and may or may not be linear. In some embodiments, when functional insert 39 is fully retracted, its components 45 look as if they may be a unitary piece when viewing the upper surface or face 29 (see, e.g., FIG. 7). The functional insert 39 will have at least two moveable components 45, said components translation in unison. The functional insert may have at least three independent and moveable components 45. The functional insert may have more than three independent and moveable components 45.

[0057] In use as a deblocking tool, it is understood that the functional insert 39 may comprise any desired configuration as long as at least a portion of the functional insert 39 is adapted at least on its interior 34 to have a portion of which is a gripping surface that can be mated with and grip firmly one or more portions of a button or a block for deblocking of a lens or lens blank. Said gripping surface may include a single surface (e.g., continuous surface) or more than two points along the interior 34 of the functional insert 39; the gripping surface(s) need only be sufficient to ensure rotation of the button or block which will occur as the components 45 of the functional insert are retracted to surround and, hence grip, the desired portion of the button or block. As is understood by those of skill in the art, buttons that may be attached to the surface of a lens may be of various sizes, shapes, and materials. One example of a material used is PTFE. See also U.S. Patent No. 5,421,771, the entirety of which is incorporated herein by reference. The buttons may in any size or range of sizes. Representative sizes range from about 10 to about 100 mm in diameter. Other suitable sizes may be from about 15 to about 25 mm in size. Scaling up or scaling down of device 37 may also be performed and will often depend on the article to be gripped and moved by the device 37 described herein.

[0058] For mating with an article, face(s) 29 and/or the interior 34 of the functional insert 39 need only be cooperative and in contact with a portion of the article (e.g., button or block). And, the article (e.g., button or block) may be of different outer configuration than the configuration of the interior 34 of the functional insert 39.

[0059] With operation of a device 37 described herein, as the gripping members 9 are moved toward each other, by a hand gripping pressure or by robotics, as examples, the functional insert 39 of the device 39 translates outwardly to "mate with" the article (e.g., button or block), allowing the user or robot to secure the article for removal by gripping with all or portions of the interior 34 of the functional insert. For example, when the device 37 (e.g., functional insert) moves towards the lens blank or lens to which the button is secured, the functional insert is released outwardly in order to prepare for gripping. To grip the button, the functional insert retracts inwardly. When the device 37 by way of the functional insert grips the button, the functional insert is moved away from the lens blank to which the button is secured and the button is detached (linearly and/or rotationally) from the lens blank. With both linear and rotational motion of the functional insert through a simple closing operation of the handle section, the described device 37 by design allows the user to reduce (or no longer require) a "twist and fly-away" method practiced with alternative deblocking devices used during removal, and instead guides a user to use a clean break. In one embodiment, the device 37 may have an audible and/or tactile lock/unlock mechanism (not shown) which would allow a user to lock the gripping members 9 into place when in place (e.g., preset for any desired article) without using any additional pressure, thereby reducing the amount of force required by a user.

[0060] A pin and groove mechanism may facilitate translation and/or rotation of the functional insert 39. The pins (not shown) may be attached to or molded as part of the functional insert 39 or may be formed (molded or attached) as part of the head section in region 21b. In one embodiment, the pins project from an inner surface of sidewalls that form an opening or insertion hole at the proximal end of the head section (e.g., pins projects from sidewalls 59 that form the insertion hole 54 at the end 27 in region 21b of head section 25, shown without pins in FIG. 6) into at least one groove formed on the moveable member. In another embodiment, the pins project from the moveable member and the at least one groove is formed along the inner surface of the sidewalls that form the opening at the proximal end of the head section (e.g., one or more grooves 60 formed on sidewalls 59 that form the insertion hole 54 at the end 27 in region 21b of head section 25, as representatively depicted in FIG. 6). The pins 62 may be replaced by bearings 62 to further assist in smoothe movement along one or more grooves 60 (see, e.g., FIG. 11) At least one groove when formed in a spiral pattern allows clockwise or counterclockwise rotational movement of the functional insert 39 as each pin travels along the spiral groove path. As an alternative, a pair of grooves that intersect every 180 degrees may be patterned allowing both alternative rotations in a single embodiment. The pitch of the one or more grooves may vary as needed. Pin placement may also affect the degree of rotation. In addition, at least one groove, or optionally a pair of grooves 61, may be formed on the sidewalls that form the opening of the proximal end of the head section (see FIG. 12) as well having an opposing groove (or optionally a pair of opposing grooves) formed on the moveable member; movement is then provided by opposing grooves forming a spline into which one or a plurality of balls are positioned for smoothe movement.

[0061] In one example, a representative description and method of use of the device includes the spring-loaded tension member 19 (e.g., wire, etc.) that may be positioned in each hollow cavity 15 of the gripping members 9, as illustrated with FIG. 1. The spring-loaded tension members 19 may be in the form of a spiral or a coiled compression wire. An example is tension members 19 composed of stainless steel or a similarly strong alloy or composite that occupies a space (e.g., about 20 mm) of each hollow cavity 15 of each gripping member 9. This representative described tension member 19 provides resistance or tension to when pressure is applied to the gripping members 9 by the user or robot, as examples. In the unbiased state the tension member 19 bears against the inner wall surface formed by each hollow cavity 15 of gripping members 9 and constantly urges the gripping members 9 toward an open or unbiased position. Generally, each spring-loaded tension member 19 abuts up against a portion of the inner surfaces of the hollow cavities. The distal end of each tension member 19 may have a freely moveable or unsecured first or distal end and a second or proximal end that may be secured or held firmly in place at or near its proximal most ends near or within end region 43. Securement of the proximal end usually includes the stop means 11. The stop means 11 may include but is not limited to, for example, a soft metal anchor plug. It may also be a member for permanent securement of the moveable member, for example, by a permanent adherence to the moveable member by soldering and/or by another anchoring means. Thus, the tension member 19 may be detachably held in the hollow cavity 15 or may be undetachably held within the hollow cavity 15. In one instance, the tension member is glued in place in the hollow cavity 15. Each tension member 19 may be injection molded in one piece when forming the hollow cavity 15, using a material such as, for instance, stainless steel, acetal plastic, or the like. The tension member or spring 19 may be formed in such a way that it will sit firmly in the hollow cavity 15, such that its proximal end part is in one piece within the hollow cavity. The tension member 19 may also be bent into different directions. The tension member 19 may be caused to take different positions or paths. In one instance, the tension member is guided by at least one guide member 17. Guide member 17 may be in the form of a ring that surrounds or otherwise holds at least a portion of the tension member while allowing some transverse movement of the tension member 19. The guide member 17 need not be entirely circular; it may instead generally be of a shape or capable of molding or otherwise configuring into a shape formed by a boundary wall of the hollow cavity 15. The guide member 17 may be secured to the inner boundary wall surface of the hollow cavity 15 or to a lining member within the inner boundary wall surface. The guide member 17 helps define a first position which is an inactive position for the tension member 19, where it does not exert any separating force upon the gripping members 9 in use, and a second position, which is an active position for the spring mechanism or tension member 19, in which it exerts a separating force upon the gripping members in use. In this latter position, the distal free end of the tension member 19 comes into abutment with an inner portion (boundary wall surface) of the hollow cavity and/or the functional insert 39. In another embodiment, one or a plurality of grooves or other guides positioned along the inner boundary wall surface of the hollow cavity 15 of the gripping members 9 help further guide the tension member 19, and the tension member 19 may be easily moved between the guide(s) or groove(s).

[0062] In another example, a representative description and method of use of the device includes a tension member 19 as a threaded screw member that may be positioned in relation to the gripping members 9, as illustrated with FIG. 2. Here, the screw member 19 is positioned along the central axis of the body of the device 37; a proximal end 19b of the screw member 19 may have a portion which projects into a cavity region formed between gripping members 9. The distal end 19a of the screw member 19 will associate with the head section 25. The entire screw member 19 is axially rotatable along the central axis of the device 37. Rotation (e.g., via threading) of screw member 19 provides rotation of the functional insert 39, and hence expansion of its two or more components 45, as described previously. A bushing 23 may be positioned to surround at least a portion of the screw member 19. The bushing 23 may be made of a pliable but strong material, such as rubber. Bushing 23 is used for stabilization and central support of the screw member 19. The association between the screw member 19 and the functional insert 39 may include a hinge mechanism 33. This is further illustrated in FIG. 3. In the embodiment of FIG. 3, the tension member 19 shown is a spring-like structure that may replace or coexist with screw member 19. The hinge mechanism 33 securely and/or removably affixes the functional insert (via its two or more components 45). Tension member 19 (as either or both a screw, shown in FIG. 2, or a spring, illustrated in FIG. 3) translates the functional insert 39 from an inward (retracted) to an outward (expanded) position. Securement of the functional insert 39 with the hinge mechanism 33 may be by adhesion, by screwing, and by weldment, as suitable but non-limiting examples or permanent placement, or may include a coupling or fitting that is removable, as described above.

[0063] In still another example, a representative description and method of use of the device includes a tension member 19 as a pre-loaded tension spring or coil spring or ribbon spring that may be centrally positioned, as illustrated with FIGS. 4-8. Here, the spring member 19 is positioned about guide member 17 along the central axis of the body of the device 37, such that a proximal end 17b of the guide member 17 is bounded and/or secured via shoulder bolt 57 of stop member 11 and a distal end 17a is bounded and/or secured by the proximal end 27 of the head section 25. Shoulder bolt 57 of stop member 57 is rotatable with respect to a receiver 58 formed through the interior of jacket 50. In one embodiment, the moveable member as depicted in FIGS 4-10 as guide member 17 is provided with a configuration comprising two spiral grooves (e.g., helically patterned with opposing rotations) that intersect when displaced 180 degrees from each other. In one such embodiment, each groove has a pitch of approximately 15 mm, when measured as one full revolution on a vertical plane based on the moveable member having a cross sectional diameter of 9 mm. The two-groove configuration allows rapid rotational translation in both directions. While guide member 17 in FIGS 4-10 is depicted as having such a surface configuration of intersecting grooves, only a single groove may be provided, or alternatively, other configurations discussed previously may be acceptable for displacement of the guide member 17. Jacket 50 of stop member 11 adjoins at opposing hinge or interlocking regions 31 with gripping members 9 by way of the proximal most ends of the gripping members, at end region 43. The interlocking regions 31 shown having a floor and a back wall 20 limit movement of gripping members 9 at the end regions 43. Gripping members 9 are further limited in movement by their shape, shown in the drawings to be somewhat arcuate shaped with a small bend 28. It is understood that other shapes of gripping members are similarly acceptable, which may include any number of bends, angles, curves, and/or ergonomic forms. Further limiting the movement of gripping members 9 at end region 43 is the sidewalls of lip 30 of shoulder bolt 57. The guide member 17 is further configured at its distal end for engaging with head section 25, entering through the insertion hole 54 and pinned by a shaft (not shown) that is formed in through hole 63, shown best in FIGS. 4B, 6 and 10. In the embodiment of FIG. 10, the moveable components 45 are shown spaced apart when in a more retracted state. Engagement may include and/or be replaced by a threaded engagement, wire, spring, bearing, etc. (not shown). Spring member 19 may or may not be secured at its distal end and/or its proximal end. Securement, when included, may be by weldment or other bonding which fixed secures it or may be by a means for removable securement. With a squeezing force or an exerted pressure applied inwardly to each gripping member 9 towards the central axis, guide member 17 is slideably and/or threadedly eased within head section 25 via insertion hole 54. With continued force or pressure and sufficient displacement of guide member 17, which occurs as gripping members 19 moves from an unbiased (open or first) position to a biased (second) position, functional insert 39 is suitably extended outwardly from the cavity at the distal end 26 of the head section 25. The two or more components 45 of the functional insert 39 expand away from each other with slideable and rotational motion of the guide member 17; said expansion may be assisted by a biasing (e.g., spring or release mechanism not shown) held within recess 48 that is formed on opposing side edges of components 45, as depicted in FIGS. 4B, 6 and 10. Tension member 19 provides tension, returning gripping members 9 to their open (first or unbiased) state. In FIGS 4-10, while a spring member 19 is shown, it is understood that in some embodiments, spring member 19 is not essential or may be replaced by one or more alternative tension members. Further, alternative guide member(s) may replace said guide member 17 or may be included with said guide member 17, including tabs or pins or threaded members (in addition or in replacement).

[0064] In a representative example of an apparatus provided for deblocking in ophthalmic applications, a device 37 will include the functional insert, and together the apparatus may be approximately 6 inches long from the proximal portion 3 to the distal portion 5 and between about 2 inches and 3 inches wide at the widest part of the gripping members 9 when in its unbiased state. In the biased or closed state, the gripping members may have a width that is between about 1 inch to about 1.5 inches at the widest point. Additional sizes are readily contemplated. The apparatus when configured with the functional insert may be customized for any use requiring movement between an unbiased position and biased position as described herein. Customization may include any suitable insert as long as the insert is functional between retracted and expended positions. Customization may include linear and/or rotational movement with application of a force to the gripping members 9. Suitable customizable applications include the food industry, dental industry, microelectronics industry, cosmetics industry, as representative but non limiting examples.
