United States Patent 3,388,468 PROTECTIVE DEVICE James P. Hamill, 4111 Connecticut Ave. NW., Washington, D.C. 20008 Filed Apr. 20, 1967, Ser. No. 632,235 1 Claim. (Cl. 30-90) ABSTRACT OF THE DISCLOSURE A cover for a safety razor, the cover being constructed of flexible material, including means for removable attachment to a safety razor and having means inter-engageable with a portion of the razor.

Background of theinvention (1) Field of the invention-This invention pertains to a protective device in the nature of a removable cover for a safety razor.

(2) Description of the prior art.--Prior proposals for removable covers for safety razors have included snap-on devices of metal and frictionally engaged covers formed of other materials. Examples of these prior proposals drawn from the patented art include those shown in United States Patents Nos. 3,177,582 and 3,290,778. Such prior devices have been subject to criticism with respect to their material of fabrication, cost of manufacture, and most significantly, their ability to remain in place in use as a function of their ease of demounting.

Summary of the invention This invention pertains generally to protective covers for sharp devices and more specifically to a cover for a safety razor to protect the exposed blade edges during periods of non-use, such as in travel, storage, and the like.

A basic objective of this invention resides in the provision of a 'blade guard of the type indicated above which is readily attachable and which is securely and positively held in place during use. A related objective is to provide individual means for the mounting and demounting of the cover, said means being conveniently located for maximum efficiency of operation.

Another advantage of the present invention concerns the provision of a cover formed of inexpensive plastic material, serving to shield the blade portion of the razor from contact with other objects and additionally functioning to cushion the razor and to thereby prevent damage thereto from contact with other articles. A related objective resides in the provision of novel opening means for the cover, the opening means being of resilient, hollow form, providing a shock absorbing top cover.

Other and further objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification and drawing.

Brief description of the drawing FIGURE 1 is a perspective view of a protective device constructed and assembled in accordance with the teachings of this invention;

FIGURE 2 is an enlarged end elevational view, showing the device in place on the head portion of a standard safety razor; and

FIGURE 3 is an enlarged sectional view taken on the line 3-3 of FIGURE 1, looking in the direction of the arrows.

Description of the preferred embodiment Referring to the drawing in more detail, a protective device is therein shown by example in FIGURES 1 through 3 and is identified therein by reference numeral 10. The device finds its primary area of utilization ice in combination with the head 12 of a conventional safety razor 14. The head includes a top comprised of a pair of opposing, curved plates 16, 18 hinged at the opposite sides of the razor and overlying the major portion of a blade 20 having exposed cutting edges 22 and 24 extended outwardly of the distal side edges of the plates 16 and 18 respectively. The blade is pressed against a base member 26 by the plates, and the base has a down-turned lip 28, 30 at each of its sides.

The protective device 10, in the preferred form herein shown, comprises a unitary main body portion 32 formed of a pliable plastic material and comprising a main panel 34 of curvilinear form. The panel 34 is dimensioned to overlie the cover plates 16 and 18 and the exposed edges 22, 24 of the blade and has inner and outer surfaces 36, 38, ends 40, 42, and sides 44, 46. Side walls 48 and 50 are integrally joined to the sides of the main panel in generally perpendicular relation thereto, and each has a top end 52 and a bottom end 54.

For spreading the opposing jaw portions of the cover described below preparatory to mounting the cover on a razor, and to provide the cushioning top guards hereof, inclined sections 56, 58 extend from the top 52 of the Walls 48 and 50 and are joined to the outer surface 38 of the main panel 34 at spaced locations. This permits the device to be opened by the application of inward pressure to the walls 48 and 50, and it will be observed that, in conjunction with the outer walls, the inclined sections define hollow, resilient chambers.

The first of the jaw members hereof above mentioned comprises an inward flange 60 projecting inwardly from the bottom end 54 of the side wall 50. The wall is of a depth such that the flange extends below and frictionally grips the lip 30, and the flange preferably has an outer, rigidifying rib 62 on its distal end.

Second jaw means of the invention is comprised of engagement means for the lip 28 and includes an inwardly extended arm member 64 having a lug -66 of frustopyramidal shape coextensive in length therewith and projecting upwardly for engagement behind the lip 28. The outer end of the arm member 64 has a reverted grasping element 68 thereon.

In use, the device 10 is applied to a razor by the application of manual inward pressure on the upper sections of the walls 48 and 50. When the pressure is released, the jaws engage the down-turned lips of the razor, with the lug 66 seating positively behind one of said lips. Release is accomplished via the outward disengagement of the lug by pulling on the grasping element 68.

Having described and illustrated an embodiment of this invention in some detail, it will be understood that this description and illustration have been offered only by way of example, and that the invention is tobe limited in scope only by the appended claim.

I claim:
