SAFETY RAZOR GUARD Filed Feb. 11, 1966 INVENTOR. l3 F250 E1 J'omss FIG: 5 J' 01/ 1 AVA/I649) M itmg United States Patent 3,396,465 SAFETY RAZOR GUARD John V. Knight, 7924 Olson Memorial Highway 55427, and Fred E. Jones, 5905 Westbrook Road 55422, both of Minneapolis, Minn.

Filed Feb. 11, 1966, Ser. No. 526,736 1 Claim. (Cl. 3090) ABSTRACT OF THE DISCLOSURE A guard for the head of a safety razor consisting of a tubular member to accommodate the head of a safety razor and a keyhole slot extending inwardly from an end of one wall of said member, said slot having an inwardly extending tapered width forming a restricted portion permitting the frictional passage of the handle of a safety razor therethrough, said restricted portion opening into the inner end portion of the slot wherein the handle of said safety razor is received.

The invention herein relates to an improvement in a guard device for a safety razor. As is known, a safety razor equipped with a blade has an exposed cutting edge at one or both sides of the razor head.

In the use of a safety razor, the blade therein is generally not removed until it is replaced and a blade will hold a satisfactory cutting edge for a substantial number of shaves. The inventors have no knowledge of the commercial existence of a simply constructed guard for the head of a safety razor.

The invention herein relates to a readily applied and removable enclosure for the head of a safety razor held in position by a slot having a frictional locking means with respect to the handle of said razor.

It is an object of this invention therefore to provide a simply constructed guard to enclose the head of a safety razor.

It is a more specific object of this invention to provide a simply and inexpensively made guard device which can be readily removably installed onto a safety razor head comprising a tubular member to enclose the same and fully overlie the exposed cutting edge or edges of the blade, as the case may be and to be retained thereon by having the handle of said razor held in a keyhole slot formed in one side of said guard.

These and other objects and advantages of the invention will be set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

FIG. 1 is a top plan view of the invention herein;

FIG. 2 is a broken view in end elevation showing the invention in operating position;

FIG. 3 is a bottom plan of the view in FIG. 2 with a portion broken away;

FIG. 4 is a view in side elevation with a part broken away;

FIG. 5 is a bottom view of the invention in perspective;

FIGS. 6-9 respectively show views in top plan, end elevation, bottom plan and side elevation of a modification of the invention.

With reference to the drawings, the device embodying the invention herein is indicated generally by character 10.

Said device 10 is shown here comprising a housing member substantially tubular in form and hereafter referred to as a housing. Said housing may be made of a suitable somewhat flexible lightweight material, such as of an appropriate plastic material.

Said housing in the specific form here shown has a top wall 12, a bottom wall 13 and side walls 14 and 15. The ends 16 and 17 of said housing are open.

Formed in the bottom wall 13 is an elongated slot 18 here shown in the general form of a keyhole slot having a semi-circular inner end portion 19, a neck portion 20 of a reduced width and flaring side portions 21 extending to said open end 18.

Projecting outwardly from the sides 14 and 15 are finger grip or holding members 22. These members may be variously formed and are shown here as projecting studs having concavely curved end portions to provide a finger hold.

For purpose of illustration, a conventional type of double edge safety razor 25 is shown having a head portion 26, a handle 27, with said handle having a portion 27a of reduced width adjacent said head portion. Loaded in said razor head is a blade 28.

In operation, the guard device or housing 10 will be taken in hand held by two fingers engaging said projections 22 and with the razor held in the other hand, the housing will be slipped over the razor head to receive the same therein and the handle portion 27a will pass through said slot to be received and retained within said end portion 19.

In connection with forming said slot 18, the neck portion 20 will be somewhat less in width than the width of said handle portion 27a. Hence said handle portion 27a will pass through said neck portion 20 with some frictional engagement with the sides thereof. There will be just sufiicient frictional engagement to prevent the housing from slipping off of the razor head but not so much as to make difiicult the removal of said housing by hand. Said slot will be of sufficient length for said housing to receive the head of a razor completely therein. In cross section said housing will be of such width and configuration as to avoid contact with the exposed edges of said razor blade 28.

Modification With reference to FIGS. 6-9, a modification is shown of the device 10 above described. All portions of said modified form which are the same as like portions of said device 10 are indicated by like characters with a prime added.

The modification present in said device 10' is in the treatment given the sides 14' and 15 to provide holding means. In lieu of the projections 22 above described, here the sides 14' and 15' have projecting outwardly therefrom serrated or transversely grooved strips 30'. Said strips will be formed integrally with said sides.

Thus it is seen that we have provided a simply constructed and easily handled safety razor head guard to receive and completely enclose the head of a safety razor and exposed edges of a razor blade therein which is retained thereon by slipping the handle of said razor into a tapered keyhole slot.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention which, generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claim.

What is claimed is:

bination,

a tubular member having open ends and being ar ranged to receive therein the head of a safety razor,

one of the walls of said member having a slot extending inwardly from one end thereof,

said slot comprising inwardly convergin side walls forming a portion of such restricted width of said slot that said side walls frictionally engage the handle of a safety razor passing therethrough,

said portion of restricted width diverging into, an enlarged inner end portion of said slot to receive said handle of said safety razor, and said tubular member having gripping means on either side thereof.
