Title: Modular Anchoring System for Pole Supported Devices Inventor: Richard P. Helmonds

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001 ] This application claims priority from U.S. Patent Application USl 1/841,696, "Modular Anchoring System for Pole Supported Devices" filed August 20, 2007, and also from U.S. Provisional Patent Application number US60/926,106, "Modular Anchoring System for Pole Mounted Consumer Products" filed April 24, 2007. The content of these references are incorporated by reference in this international application.

TECHNICAL FIELD

[0002] This application relates to a system of devices for anchoring a support pole to a variety of objects and the ground.

BACKGROUND ART

[0003] Devices to anchor support poles to a desirable surface, such as a structural member or the ground, are known in the art. U.S. Patent 6,401,736 (Jerry) shows both a c- clamp and stake support as parts of an umbrella shaft. U.S. Patent 6,471,176 (Berthlaume) shows a staff support device for use on a flat surface, or for burial in sand, with a chuck mechanism for attachment of the support to the shaft and, in one embodiment, a pin bayonet mechanism for assembly of the device. U.S. Patent Application Publication 2006/0054772 (Priscott et al.) shows a multi-jointed clamp and stake support with a chuck mechanism for attachment to the shaft. U.S. Patent Application Publication 2006/0207640 (Connelly) shows an umbrella with a shaft handle with interior threads and c-clamp and stake supports that can be threaded to the handle.

[0004] It is desirable that an anchoring system be economical of manufacture, be usable on a wide range of desirable surfaces, including structural members of a large variation in thickness, and be easy to erect.

DISCLOSURE OF INVENTION

[0005] The modular anchoring system for pole-supported devices is a combination of devices for anchoring a pole to a desirable surface. The pole may be used to display or support a multitude of objects such as umbrellas, banners, flags, signs, shelters, screens, barriers, fishing rods and projection screens.

[0006] A first device of the combination is a common base with a first end and a second end and an outer surface between the ends. The first end has an attachment opening symmetrical about the centerline of the base providing means for removable attachment to a pole end. This includes arrangements to either removably or semi-permanently attach the base to a pole to be supported, such as with a screw, rivet, or pin. The common base provides anchoring means to anchor the pole no matter what desired surface is chosen. [0007] The common base second end has a uniform circular outer surface with anchoring means for removable attachment to a ground base including two or more attachment projections located at substantially symmetrical arcs of the base periphery and extending beyond the base outer surface to provide a base attachment connection. The attachment projections have a first edge, a second edge, an outer edge, and the base second end outer surface defining the upper surface boundary of the projections. This upper surface slopes between the first and second edges. The attachment projections extend beyond the base second end with a lower surface arranged to rest upon a substantially flat surface. [0008] The common base outer surface also has an engagement opening anchoring means arranged between the first and second ends providing means for removable attachment to a clamp.

[0009] A second device of the combination is a clamp used to anchor to a structure with opposing sides. In one embodiment the clamp has a general sideways u-shape with an engagement arm to engage the common base engagement opening at the upper end of the u, providing means for removable attachment to the common base, and a threaded opening engaging a threaded rod at the lower end. The threaded rod has a handle end used to turn the threaded rod, and a clamping end configured to engage a flat surface. To use this clamp, the common base is supported on a first surface of a structural member with opposing surfaces. Then engagement arm is engaged with the common base central portion and the threaded rod is tuned so the rod clamping end engages the second surface of the structural member with opposing surfaces, and provides means for adjustably clamping to a structural member opposing sides by anchoring the clamp and common base. The pole is, of course, attached to the common base and also supported.

[0001 0] In another embodiment the clamp is adjustable with an L-shaped member and an adjustment mechanism. The L-shaped member upper portion is arranged to enter and engage the common base engagement opening end and the lower portion is arranged substantially at

a right angle to the upper portion. This lower portion has a multiplicity of adjustment notches. The adjustment mechanism has a substantially round threaded opening and a substantially rectangular coarse adjustment opening. The coarse adjustment opening is sized for passage of the L-shaped member lower portion when the threaded rod axis at a non-parallel angle to the L-shaped member lower portion axis. The coarse adjustment opening engages one of the L- shaped member lower portion notches when the threaded rod axis at a parallel angle to the L- shaped member lower portion axis. To use this clamp one places the common base second end on the desirable surface of a structural member with an opposing side, engages the clamp interference arm with the common base engagement opening, and turns the clamp handle end to engage the threaded rod clamping end with the opposing side of the desirable surface. This removably anchors the devices on the structural member such that a pole inserted in the common base attachment opening is supported by the devices.

[0001 1 ] A means of positively engaging the clamp in the common base includes the common base engagement opening containing a set of clamp end engagement surfaces, a clamp lower engagement protrusion, and a clamp upper engagement spring pin. The clamp engagement arm then has an upper engagement indentation that engages the common base clamp upper engagement spring pin, a lower engagement indentation that engages the common base clamp lower engagement protrusion, and a set of end engagement surfaces that engages the common base clamp end engagement surfaces. Inserting the clamp engagement arm into the common base engagement opening and positioning it such that the common base features engage the clamp features indicates proper placement of the clamp in the base and removably attaches the clamp to the base.

[0001 2] The third and fourth devices of the combination are used together. The third is a ground stake with a body and a head. The body outer surface is tapered and the head has a top surface and a lower surface that extends outside at two or more portions of the body outer surface. The fourth is a ground base with an outer periphery, a lower side, an upper side, a centrally located stake support protrusion extending beyond the upper side to a protrusion upper surface, and two or more support tabs. There is a stake support opening providing means for removable attachment to the ground between the lower side and the stake support protrusion upper surface that receives the ground stake outer surface through the opening and provide supportive contact between the protrusion upper surface and the inserted stake head lower surface. The base outer periphery extends beyond the upper side and has an internal periphery engagement slot arranged to engage the common base second end attachment

projection outer edges, and a multiplicity of support tabs that match the number of attachment projections on the common base and provide means for removable attachment to the common base. These support tabs are arranged in substantially symmetrical arcs. Each one has an upper surface and a lower surface, the lower surface defining an engagement slot between the surface and the ground base upper side. The slot is arranged to engage the common base attachment projections. These devices are used by placing the ground base lower side on a desirable ground surface and driving a stake body through the ground base opening such that the ground base is removably attached to the ground by contact with the stake head providing means for attaching the ground base to the ground. Then the common base is inserted in the ground base internal periphery engagement guide and turned to engage the attachment projections between the ground base support tabs and upper side. This removably anchors the devices to the desirable ground surface.

Objects and Advantages

[0001 3] One object of the present invention is to provide a pole anchoring system for use on multiple desirable surfaces.

[0001 4] A second object of the present invention is to provide a pole anchoring system in which one device of the system may be connected to the pole and used to anchor the pole to multiple desirable surfaces.

[0001 5] A third object of the present invention is to provide a pole anchoring system that requires minimal time to anchor the pole.

[0001 6] A fourth object of the present invention is to provide a pole anchoring system which accommodates a broad range of desirable surface dimensions and compositions.

MODES FOR CARRYING OUT THE INVENTION

[00084] The modular anchoring system for pole-supported devices is a combination of devices for anchoring the pole to a desirable surface such as near the edge of a structural member with opposing sides, or the ground. The common base (102) as shown in FIGs. 1

through 10, FIGs. 12 a through 15, and FIG. 17 is a central feature of the invention. This device provides attachment to the pole, which is inserted in the attachment opening (104) placed symmetrically on the centerline of the common base (102), and the pole is attached using a fastener (example screw, rivet, or pin) through the fastener openings (124) shown in FIGs. 1 and 2. The common base (102) then provides anchoring of the pole to a variety of surfaces using the other devices of the system. An example of the common base attached to a pole, which in turn is supporting an umbrella is shown in FIG. 3.

[00085] The common base (102) end opposite the attachment opening (104) has a set of attachment projections (106) located in symmetrical arcs of the common base substantially round periphery that provide a base attachment connection. There are three attachment projections (106) in the embodiment shown in the figures, but there may be as few as two and there could be more than three. Each attachment projection extends out from the outer surface of the common base (102) at the end to form a first edge (108), second edge (110) and an outer edge (112). The edges define an upper sloping surface (114) that slopes between the first edge (108) and second edge (110). The lower surface of the attachment projections forms a flat surface that may be used to provide stability of the common base (102) on a surface. There are engagement openings (116) in the surface of the common base (102) located between the end with the attachment opening (104) and the end with the attachment projections (106). These openings may be through openings as shown or a single opening. In either embodiment the opening is shaped, and provides surfaces at the entry opening and near the end of the opening, to be used with the clamp (140). The surfaces contain the base clamp end engagement surfaces (118) and the base clamp lower engagement protrusion (122). Projecting into the opening, near the end of the opening, is a base clamp upper engagement spring pin (120). This provides a positive engagement with the clamp. [00086] The adjustable clamp (152), shown in FIGs. 4a, 4b, 5, 6, 7, 8, 9 and 10, is used to support the common base (102) near the edge of a structural member (400) with opposing surfaces. Two embodiments of the clamp are shown in FIGs. 4a and 4b. The clamp embodiment in FIG. 4a has an engagement arm (142) arranged to engage the common base (102) engagement opening (116). The opposite end of the engagement arm (142) has a threaded opening (144) arranged with a threaded rod (146). The end of the threaded rod (146) facing the engagement arm (142) surface that engages the common base engagement opening (116) has a clamping end (148) that engages the opposing side of the structural member from the side the common base (102) attachment projections engage. The opposite end of the

threaded rod (146) is the handle end (150). The handle is used to turn the rod to adjust the clamp to the thickness of the structural member and to clamp the common base (102) to the structural member by tightening the clamp threaded rod (146) to anchor the system to the structural member by the force exerted between the common base (102) attachment projections (106) lower surface and the clamping end (148) of the clamp threaded rod. [00087] An embodiment of the clamp (140) to accommodate anchoring to a wider range of thicknesses of structural members is the adjustable clamp (152) shown in FIGs 4b and 5 through 10. This embodiment has two pieces, an L-shaped member (154) and an adjustment mechanism (162). The L-shaped member (154) has an upper portion (156) that has a surface that engages the common base (102) engagement opening (116). At approximately a right angle to the upper portion (156) is the lower portion (158) that has adjustment notches (160) in two opposing sides of the lower portion (158). Another embodiment may have notches in just one of the sides. The adjustment mechanism (162) has a threaded opening (144) and a coarse adjustment opening (164) shown in the cross-section view of FIG. 6. The threaded opening (144) is arranged with a threaded rod (146). One end of the threaded rod (146) has a clamping end (148) that engages the opposing side of the structural member from the common base (102) and the other end is the handle end (150). The coarse adjustment opening (164) is shaped to fit over the L-shaped member (154) lower portion (158) and an upper and lower edge retaining protrusion (176) is shaped to engage the adjustment notches (160). The coarse adjustment opening (164) axis is at an acute angle to the threaded rod (146) axis on the side with the threaded rod clamping end (148). This angle is obtained by creating a "dog leg" in the adjustment mechanism (162) as shown, or, in an embodiment, may be created by forming the coarse adjustment opening (164) at an angle to the threaded opening (144). The angle is selected so when the threaded rod (146) axis is at a non-parallel angle to the L- shaped member lower portion (158) axis, the adjustment mechanism (162) is free to slide along the length of the L-shaped member lower portion (158) as shown in FIG. 7. Conversely, when the adjustment mechanism (162) is rotated as shown in FIG. 8, the threaded rod (146) axis is turned to become essentially parallel to the L-shaped member lower portion (158) axis as shown in FIG. 9. In this position, the coarse adjustment opening (164) edges engage the L-shaped member adjustment notches (160) preventing relative movement in relation to the L-shaped member (154). This provides a coarse adjustment for the thickness of the structural member. The threaded rod then provides the fine adjustment.

[00088] As shown in FIGs. 4b, 7, 8, and 9, a retaining protrusion (176), example a pin, may be installed in the L-shaped member lower portion (158) below the adjustment notches (160) after assembly of the adjustment mechanism (162) on the L-shaped member (154). This prevents the adjustment mechanism (162) from disengaging from the L-shaped member (154) while the L-shaped member upper portion (156) is being engaged with the common base (102).

[00089] A mechanism for indicating to the installer when the either clamp (140) is correctly engaged and for providing positive engagement with the common base (102) is shown in FIG. 6. The common base (102) has base clamp engagement surfaces (118), and the base clamp lower engagement protrusion (122) located so as to mate with the end engagement surfaces (170) and the lower engagement indentation (166) on both the clamp (140), FIG. 4a, and the adjustable clamp (152), FIG. 4b. In addition a base clamp upper engagement spring pin (120) on the common base (102) mates with the upper engagement indentation (168) on the clamp (140) and the adjustable clamp (152). This pin inserts into the indentation by the spring force, providing positive engagement.

[00090] An example use of the adjustable clamp (152) with the common base (102) to support an umbrella on a structural member (400) is shown in FIG. 10. [00091 ] A stake (162) and a ground base (180) are used to support the common base (102) on the ground. The ground base (180) is shown in FIGs. 11, 12a, 12b, 12c, 13, 14, 15, and 16. The base is configured to be removably attached to the ground by the stake, and to quickly and easily removably attach to and support the common base (102). The outer periphery of the ground base (180) is shown in a round embodiment, but may be of any shape that allows a round inner periphery engagement guide (182) raised beyond, and normal to, the ground base upper side, and sized to allow insertion of the common base (102) periphery. The upper side of the ground base (180) has stake support protrusions (184), each with a support protrusion upper surface (186) as shown in FIG. 11. The stake support protrusion (184) has a stake support opening (192) between the support protrusion upper surface (170) and the ground base lower side. This opening is shaped and sized for both a round stake (162) as shown in FIG. 12a, and a cruciform stake (162) as shown in FIGs. 12b and 12c. Alternate embodiments may be shaped and sized for one shape or the other.

[00092] Either stake (200) shape, as shown in FIGs. 12a, 12b, and 12c, has a stake body (202) and a stake head (204) with a head lower surface (206) and a head upper surface (208).

The embodiment shown in FIG. 12c has a steak head extension (210) that provides a greater distance between the head lower surface (206) and the head upper surface (208). [00093] Multiple support tabs (188) are arranged substantially symmetrically around the periphery engagement guide (182). The embodiment in the drawings shows three support tabs (188). There may be more or less than three to match the number of attachment projections (106) on the common base (102). The symmetry, or peripheral angle covered, of the support tabs (188) is also arranged to match that of the attachment projections (106) on the common base (102). The support tabs (188) lower side forms an engagement slot (190) between the support tab (188) lower side and the ground base upper side that is used to anchor the common base (102). There are projections from the lower side of the ground base (180) outer periphery in the embodiment shown in FIGs 11 through 17, that form one or more discontinuities (194) arranged around the ground base (180) outer periphery. Alternate embodiments may have a flat lower side.

[00094] The ground base (180) is supported on the ground by placing it's lower sides at a desired location on the ground, placing a stake (200) body end in the ground base (180) stake support opening (192) and driving the stake into the ground by striking the stake head upper surface (208) with a hammer until the stake head lower surface (206) contacts the ground base support protrusion upper surface (186). This anchors the ground base (180) to the ground. The common base (102) attachment projections (106) are then fully inserted into the ground base inner periphery engagement guide (182), and the ground base (180) is rotated so the attachment tab (106) first edge inserts into the ground base engagement slot (190) between the ground base upper side and the support tabs (188) lower side. The thickness of the common base attachment projections (106) varies due to the upper sloping surface (114) of the attachment projection (106). As the common base is rotated into the ground base engagement slot (190), due to the sizing of the slot, the upper sloping surface (114) of the attachment projection (106) engages the ground base support tabs (188) lower side, which anchors the common base (102) to the ground base (180) which in turn is anchored to the ground by the stake (200), as shown in the cross-section of FIG. 14. [00095] The stake (200) embodiment shown in FIG. 14 is the stake with a steak head extension (210). As shown, the steak head extension (210) places the stake head upper surface (208) near a lower end of the common base (102) internal cavity. This embodiment provides improved stability of the device in very loose ground, such as sand. The other stake embodiments are not shown in cross-section but are in FIGs. 12a, 12b, and 12c.

[00096] An example of the common base (102) anchored to the ground while supporting an umbrella is shown in FIG. 15.

[00097] Another alternate embodiment of the modular anchoring system for pole- supported devices is shown in FIG. 17. Here the ground base (180) has a threaded engagement (240) that is sized to mate with a common base (102) threaded engagement (240). This embodiment has the ground base anchored on the ground by a stake (162) and the common base (102) is anchored to the ground base (180) by engaging the common base (102) threaded engagement (240) with the ground base (180) threaded engagement (240) and turning the common base until the threads are fully engaged.

[00098] Another feature of the embodiment in FIG. 17 is an extended common base (102) which increases the distance from the attachment opening (104) to the engagement opening (116). This allows the pole to be inserted into the attachment opening 9104) a greater distance, providing additional support. Those familiar with the art will recognize this extended distance may also be used on the other embodiments.

[00099] Those familiar with the art recognize there are many possible applications and variations for the modular anchoring system for pole-supported devices other than the embodiments recited. This recitation of the preferred and other embodiments is not intended to define or constrain the invention; rather the claims define the invention.

INDUSTRIAL APPLICABILITY

[0001 00] The modular anchoring system for pole-supported devices quickly anchors a pole to a structural member with opposing sides or to the ground. The common base (102) is attached to the pole. When desired to anchor the pole to a structural member the lower surface of the common base (102) attachment projections (106) are placed on one surface of the structural member. The clamp (140) is inserted into the common base (102) engagement opening (116). In one embodiment, the coarse adjustment opening (164) is adjusted to the thickness of the structural member and the threaded rod (146) handle end (150) is turned to engage the threaded rod clamping end (148) with the opposing surface of the structural member. In another, only the threaded rod (146) handle end (150) is turned to engage the threaded rod clamping end (148) with the opposing surface of the structural member. This engagement anchors the common base (102) to the structural member by the clamping force between the common base (102) attachment projections (106) and the threaded rod clamping end (148).

[0001 01 ] Removal of the modular anchoring system for pole-supported devices from the structural member is easily accomplished by turning the threaded rod (146) handle end (150) is turned to disengage the threaded rod clamping end (148) with the opposing surface of the structural member. The clamp (140) may then be removed from the common base (102). [0001 02] When desired to anchor the pole to the ground, the ground base (180) is placed at the desired location. A stake (200) is inserted into the ground base (180) stake support opening (192) and driven into the ground until the stake head lower surface (206) contacts the ground base support protrusion upper surface (186). This anchors the ground base (180) to the ground. The common base (102) is inserted into the ground base (180) ground base inner periphery engagement guide (182). The common base (102) is then rotated to anchor it to the ground base (180).

[0001 03] Removal of the modular anchoring system for pole-supported devices from the ground is easily accomplished by turning the common base (102) to disengage it from the ground base (180). If desired, the ground base (180) may easily be disengaged from the ground by using a prying device (300) (example a claw hammer) to engage the ground base discontinuity (194) opening and prying the stake (162) out of the ground as shown in FIG. 16. This provides means for assisting removal from the ground.

[0001 04] Manufacturing the system devices uses one or more of the methods of plastic injection molding, machining, or metal die casting.
