RAZOR HEAD GUARD Filed Sept. 23, 1963 J7 20 22 {unw- {1 16 2o u n l W INlgNTOR PATENT ACEN T United States Patent 3,177,582 RAZOR HEAD GUARD Carl Curtis, RR. 3, Cobourg, Ontario, Canada Filed Sept. 23, 1963, Ser. No. 310,645 1 Claim. (Cl. 30-90) This invention relates to head guards for safety razors. Although it is recognized as being quite desirable to provide a head guard for a safety razor in order to protect or shield the blade edges, such guards are not in widespread use for various reasons. It is of course important that the contour of the guard be such that no contact with the blade edges occur. It is furthermore important that the guard be subject to easy and convenient applica a minor longitudinal section depending from each side of the major section, and an intermediate longitudinal section joining each of the minor sections with the major sections. The intermediate section has a cross section sharply curved with respect to the arcuate contour of the major section and an inturned flange constituting each longitudinal terminal edge portion of the strip. A longitudinally extending rib projects from each of the intermediate sections, these ribs constituting a handle for the guard and being swingable towards each other to impart bending movement to the major section and to swing apart the minor sections and the flanges.

It is an object of this invention to provide a head guard for safety razors which is of simple, inexpensive manufacture, which acts as an effective shield for the blade edges without risk of damage thereto, which is adapted to securely maintain its position on the razor head, and which may be conveniently and quickly applied to and removed from the razor head.

The invention will be described with reference to the accompanying drawing, in which FIGURE 1 is an end elevation of a razor head with an associated guard in accordance with the invention,

FIGURE 2 is an end elevation similar to FIGURE 1 but showing the guard in substantially locked position on the razor head, and

FIGURE 3 is a perspective view of the razor head and guard assembly.

, Referring to the drawing, 10 is a conventional safety razor head having a blade seat member 11, a blade 12 and a movable blade positioning and retaining frame 13. Frame 13 has a blade positioning rib 14, and a pair of pivotally mounted cover plates 15 each with an actuating lug 16. The blade seat member 11 has depending blade guard lips 17 beneath which are located the lugs 16 for engagement with the lips to effect opening movement of the frame, all in the usual manner.

Thehead guard in accordance with the invention is indicated at 18 and comprises a strip of thin, spring sheet material of form-retaining rigidity such as spring metal or plastic composition. In cross section, the strip has a major longitudinal section 19 of arcuate contour, a minor longitudinal section 20 depending from each side of section 19 and joined thereto by a relatively sharply curved intermediate section 21. Each longitudinal edge portion of the strip comprises a substantially flat inturned flange 22.

Projecting outwardly from each intermediate section 21 is a longitudinally extending rib 23 constituting a handle member.

In use, the sections 20 with flanges 22 are sprung apart by grasping the ribs 23 and pressing them towards each other. The guard is then placed over the razor head as shown in FIGURE 1. It will be observed that, in this condition of the razor head, the blade set is in partially elevated position, the edges of lips 17 being slightly above lugs 16. Following this procedure, the handle of the razor is further actuated to fully raise blade seat 11. Since the rib 14 is in engagement with the inner surface of section 19, this elevating movement will cause the edges of lips 17 to engage the inner surfaces of flanges 22. Thus, the guard 18 is securely clamped in position on the razor head.

It will, of course, be realized that the position of the various elements of the razor head, when the guard'is is clamped thereon as described, is that recommended when the razor is not in shaving use, i.e., the blade 12 is in freely seated and unflexed condition.

It will also be observed that, in both the unclamped and clamped positions of the guard, theinner surfaces of the depending sections 20 are spaced from the blade edges to avoid damage thereto.

I claim:

A safety razor head guard comprising a strip of flexible spring sheet material having a major longitudinal section of arcuate contour in cross section, a minor longitudinal section depending from each side of said major section, an intermediate longitudinal section joining each said minor section with said major section, said intermediate section having a cross section sharply curved with respect to said arcuate contour of said major section, an inturned flange constituting each longitudinal terminal edge portion of said strip, and a longitudinally extending rib projecting outwardly from each said intermediate section, said ribs constituting a handle for said guard, and being swingable towards each other to impart bending movement to said major section and to swing apart said minor sections and said flanges.
