Description:
RAZOR Technical Field

The present invention relates to a razor. Background Art Today, razors are known which are usually constituted by a handle, which is provided with a substantially linear shape and a handgrip, that at one end has a coupling means for a head which is usually provided with a parallelepiped shape and is arranged approximately transversally to such handle. The interconnection of the head can be of the fixed type or with the possibility of oscillation.

Two or more blades are usually constrained on the head and are arranged parallel to each other.

Such known razors have a drawback: when the edges of the blades are worn down the user is forced to grasp the head, remove it from the handle, throw away the head that is no longer of use, take a new head and reconnect it to the handle.

Such operations require time and a certain handiness on the part of the user, and above all the user should be careful to grasp the head in such a way so as not to touch the blades with his fingers in order to not cut himself, which is not always an easy operation, given the small dimensions of the head.

Further, the spare head, which has new blades, is usually placed in an appropriate container, which requires the user to remove the head from its respective seat to be placed on the handle.

Therefore, on one hand, the user is required to do an extra operating step, with the possibility of making a mistake while extracting the head and with the possibility of such head falling once it has been extracted.

Further, in the case of accidental fall the blade can lose its edge at one or more points and can thus lead to a non optimal shaving. A partial solution to such drawbacks is disclosed in EPA 07857930.7 in the name of this same applicant, wherein a razor is shown which comprises a handle provided with a support to which a cylindrical head, which is provided with blades that are arranged along a generatrix, is associated in a selectively rotatable way.

In such a solution, a handle is present, which is constituted by the handgrip for the user, from which a support protrudes which has an arc-like shape and is such that its end, having a substantially circular base shape, is arranged along an axis that is approximately perpendicular to that of the handle, and axially with respect to the handle, being provided with a first seat which has a substantially quadrangular base shape,

At the end of the support a head can be associated, which is provided with a body that has a polyhedral shape and can be axially associated, in a selective and rotatable way, to such support, the head being provided with a plurality of blades, which are arranged singularly or in pairs or more than two together, along two or more generatiϊxes of the head.

In this solution, means for adjusting the angular position of the head with respect to the support are present, these means being constituted by a protrusion, which protrudes axially with respect to the head, and is shaped compJementarily to the first seat which is provided on the end of the support.

This solution is also provided with means for the articulation of the support, which are constituted by an insert, which is made of plastics which is elastically deformable and acts as a hinge at an interruption made at the support in a region which is adjacent to the end. Further on the head there are present, at the regions not covered by blades, purposive and appropriately provided inserts or contours or depressions adapted to allow for the user to have an optimal grip with his fingers.

Such a solution, while undoubtedly valid, has some small drawbacks: the rotation to be imposed on the head requires that the user be very careful to not touch the blades, and given the fact that the regions with the purposive and appropriately provided inserts or contours or depressions are rather limited, there is therefore a risk of cutting oneself.

Further, even when the entire head must be substituted, one must still be careful not to cut oneself, as one's fingers must grasp small regions adjacent to the blades and disconnect it axially from the end of the support.

Finally it can be observed that the various blades are always exposed, and therefore even the mere manipulation of the razor can bring about accidental cuts on the user's fingers. Disclosure of the Invention

The aim of the present invention is to solve the technical problems mentioned above, eliminating the drawbacks of the known art cited, by providing a razor that allows the user to arrange new blades quickly, easily and under completely safe conditions once the previous blades have become dull, keeping one's fingers from any possible contact with the blades.

Within this aim, an object of the invention is to provide a razor that allows the operator to reset the initial characteristics of said razor after a certain usage quickly, easily and under safe conditions, keeping one's fingers from any possible contact with the blades. Another object is to provide a razor that has a simple structure while at the same time having low production and maintenance costs.

This aim and these and other objects, that will become better apparent hereinafter, are achieved by a razor comprising a handle which is provided with a support for a cylindrical head which is provided with blades arranged along a generatrix, characterized in that the support has a body on which a first radial seat and a second axial seat are provided for the interconnection and rotary support, respectively, of a knob and of a shaft provided in the head, which can be detachably associated in a vise-like manner between the support and a cover provided with first axial arms that wrap around part of the head, and second arms protruding axially from the head for the interconnection of a terminal element that accommodates an end of one or more plates, which support the blades and are associated with the body at the other end.

Advantageously, grip means are present for the user, which are accessible through the cover, are adapted to impose a rotation to the blades with respect to the support, and have means for adjusting the angular position of the blades. Brief description of the drawings

With reference to the figures, the reference numeral 1 designates a razor which is constituted by a handle 2, providing the handgrip for the user, from which protrudes a support 3 for a head 4 which is provided with blades 5.

The handle 2, which has an elongated linear shape, is connected to the support 3 by means of a curved region 2a that protrudes downward and to the right or left depending on whether the user is right-handed or left- handed.

The support 3 has, at its end, an expansion that forms a body 6 that is directed upward and on which there is a first front surface 7, which is flat and directed toward the first longitudinal axis 8 of the handle 2, and a second upper surface 9, which is perpendicular to the preceding one and is directed away from the curvature 2a for the blending of the support 3 with the handle 2 so as to reach approximately the height of the handle 2.

The upper surface 9 is slightly arc-like along a plane that is perpendicular to the second axis 10 that is perpendicular to the first front surface 7 and the first axis 8. A first seat 11 is provided at the second upper surface 9, along a plane that is parallel to the plane of arrangement of the first front surface 7 and is therefore substantially radial with respect to the body 6.

A recess 12 is provided adjacent to the first seat 11 , at the first front surface, having an arc-like shape of a chosen radius with respect to the second axis 10, a second seat 13 being provided on an axis that is parallel to the second axis, at the second upper surface 9 and on the opposite side with respect to the first front surface 7, thus being axial with respect to the body 6.

The first seat 11 , the second seat 13 and the recess 12 are provided on the body 6 so as to allow for the interconnection and the rotary support respectively for a knob 16, for a shaft 15 and for an annular guide 14 for the head 4, the shaft 15 protruding axially with respect to the head 4.

The head 4 is constituted by the knob 16 which has a substantially hemispherical shape and is provided, on its lateral surface, with a plurality of grip ribs 17 for the user's fingers and can be accommodated in the first seat 11.

The knob 16 has at the vertex the shaft 15, while on the opposite side there is a third flat surface 18 from which a stem 19 extends axially and ends at a disk 20. The distance between the third surface 18 and the facing surface of the disk 20, which both have an outside diameter that is larger than the corresponding diameter of the stem 19, defines the annular guide 14.

The outside diameter of the disk 20 and of the shaft 15 are such that they can be accommodated rotatably and supported respectively at the recess 12 and at the second seat 13 so as to keep the head 4 arranged along an axis that is parallel to the second axis 10.

The head 4 is kept rotatably associated with the body 6 thanks to the presence of a cover 21 that fastens the head 4 in a vise-like manner on the upper surface 9 of the the body 6. The cover 21 has an arc-like portion 22 that can be arranged at the annular guide 14 so as to be arranged along a plane that is substantially parallel to the plane of the first front surface 7, an arc-like band 23 protruding rearwardly at the ends of the arc-like portion 22 which partially surrounds, upon assembly, the knob 16, its lower edge resting at the second upper surface 9 and being shaped complementaiϊly thereto.

The band 23 blocks the shaft 15 from sight, can be associated temporarily with the support, and has, in the direction of the second upper surface 9, a couple of protrusions 24a, 24b that can be inserted in complementarily shaped first holes 25a, 25b which are provided in the second upper surface 9. A third seat 26 is appropriately provided at the band 23 and at the shaft 15 for the correct positioning of the shaft 15.

At the ends of the arc-like portion 22 a pair of first arms 27a, 27b protrude frontally, and thus on the opposite side with respect to the band 23, and are arranged parallel to each other and with respect to the second axis 10, which in turn is perpendicular to the first front surface 7 of the body 6.

Such first arms have a substantially laminar shape, which is preferably slightly arc-like in a transverse direction at the surfaces that do not face each other. Two pairs of second arms 28a, 28b, 28c, 28d protrude axially from the disk 20 of the head 4 along the second axis 10 that is perpendicular to the first front surface 7, such second arms also having a laminar shape and being arranged so as to face each other in pairs along diametrical planes, an empty space remaining between them which is approximately equal to the width of such second arms.

These second arms thus protrude externally with respect to the arc-like portion 22 of the cover 21 and during rotation are arranged coaxially and internally with respect to the first arms 27a, 27b, which have approximately the same length and same width with respect to the second arms. As the first arms are arranged diametrically with respect to each other, the first arms arrange themselves during the rotation of the head 4 so as to block two nonconsecutive spaces that are present between the second arms.

At the disk 20 there are also, in the interspaces provided between the second arms 28a, 28b, 28c, 28d, fourth seats 29 which are thus four in number and with which complementarity shaped interlocking portions 30a,

30b, 30c, 30d interact which are provided at one end of a corresponding number of plates 31a, 31b, 31c, 3 Id, each of which supporting a plurality of blades 5, such plates having, at their other end, second interlocking portions

32 which can be associated at appropriately provided complementarily shaped fifth seats 33a, 33b, 33c, 33d formed at an appropriately provided terminal element 34 which is disk-shaped and is provided with a second axial hole 35, which is useful to make the water flow away when the razor is rinsed.

The blades 5 are arrangeable selectively so that they are visible only at free spaces between the second arms 28a, 28b, 28c, 28d.

Two mutually opposite pairs of blades 5 are thus concealed by the first arms 27a, 27b, once the desired rotation has been performed, while a third series of blades 5, which are distinct with respect to the preceding ones, is further concealed by a third arm 36 that protrudes axially from the first front surface 7 of the body 6 on the opposite side with respect to the recess 12.

Once the head 4 has been assembled by means of the arrangement of the cover 21 on the body 6 only one out of four blades 5 arranged on the four plates 31a, 31b, 31c, 3 Id will be accessible and not temporarily concealed by the first arms 27a, 27b and by the third arm 36 thus allowing for the shaving to be performed.

The knob 16 constitutes a grip means for the user, who can impose a rotation to the head 4 by simply sliding a finger on the part of the knob 16 that is not concealed by the band 23 of the cover 21 and by the body 6.

The knob 16 further is provided with means for adjusting the angular position of the blades, such means being constituted by four teeth 37a, 37b,

37c, 37d which protrude axially, along two mutually perpendicular diametrical planes, from the third surface 18 of the knob 16, on the opposite side with respect to the shaft 15.

The teeth 37a, 37b, 37c, 37d interact selectively with sixth seats 38 which are provided on the facing surface of the arc-like portion 22, the interaction occurring possibly in a ratchet-like manner by elastic deformation of the teeth, which optionally have an inclined front surface in order to facilitate sliding, or by way of intended play between the knob 16 and the first seat 11 and/or between the shaft 15 and the second seat 13, an elastically deformable element being optionally provided. The use of the razor according to the invention is as follows. The user will grasp the razor at the handle 2; the arrangement of the head 4 is such that, at the initial condition in which the razor is calibrated, among the blades 5 only one group will be visible and accessible to perform the shaving; in particular the group of blades 5 that are approximately arranged on a plane that is parallel with respect to the third arm 36 will be accessible.

It is therefore possible to perform the usual shaving by placing the visible blades 5 on one's face and thus performing the shaving. During both the shaving and the manipulation of the razor the remaining blades 5 are concealed, so there is no danger of the user accidentally cutting one * s fingers.

Once the blades have been worn down, it is enough for the user to impose a rotation, either in a clock-wise or counter clock-wise direction according to the choice made for the construction, to the knob 16 until a new group of blades 5 have been brought into view.

Should the user want to change the whole head 4, and thus arrange a new group or set of blades 5, it will be sufficient to grasp the cover 21 and remove it from the second upper surface 9 of the body 6: at this point the user can extract the whole head 4 by grasping it by the knob 16 and the terminal element 34 and will arrange another one, in the same way, on the body 6 by fastening it in a vise-like manner by means of the repositioning of the cover 21.

It has thus been found that the invention achieves the intended aim and objects, providing a razor that allows the user to quickly and easily change the already used blades with new ones, such substitution occurring under completely safe conditions preventing one's fingers from having any possible contact with the blades.

Further the solution described allows for the head to be changed in an even quicker and easier way, preventing one's fingers from coming accidentally in contact with the blades, contact which is limited even in the condition of mere manipulation of the razor.

Naturally the invention is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Naturally the materials used, as well as the dimensions constituting single components of the invention, could be more pertinent according to requirements.

Therefore the number of blades and their arrangement along the head can be more appropriately provided as a function of specific needs. The different means for applying certain different functions do not need to coexist only in the form of embodiment shown, but can be provided in many forms of embodiment that are not shown.
