Description

May 21 1968 l.. w. sAcHs 3,383,764
v PLASTC DISPOSBLE SAFETY RAZOR Original Filed Oct. 26, 1964 INVENTOR.
5o/VAR@ w. @Ac-Hs A TTOR/Vf'KS' United States Patent O AESTRACT F THE DISCLOSURE The razor of my invention comprises a head, a separate guard member and a iblade interposed and clamped between the head and guard members. The head has integral pins extending through holes in the blade and guard membe-r. The head and guard members and pins are formed of an inexpensive disposable thermoplastic material deformable by the application of heat and pressure,
and the pins have deformed enlarged ends to permanently secure the assembly together. A handle is secured to and projects from the guard member.
This applica-tion is a division of my copending application Ser. No. 406,977 led Oct. 26, 1964, now Patent No. 3,274,683 granted Sept. 27, 1966, which is a continuationin-part of Ser. No. 293,056, filed July 5, 1963, now abancloned, and the invention relates generally to razors and refers more particularly to a plastic disposable safety razor.
l-t is an essential object of this invention to provide a razor which is inexpensive and therefore may be thrown away after being used one or two times.
Another object is to provide a razor composed of a head, guard, and a blade interposed between the head and guard, the three parts being secured together in Ia permanent assembly.
Another object is to provide a razor in which the head and guard are formed of an inexpensive easily molded material such as plastic.
Another object is to provide a disposable safety razor having .an integral part, preferably in the form of a pin shaped member, extending from the plastic Ihead and engaging the guard to form a permanent assembly.
Another object is to provide .a plastic disposable safety razor in which at least one, and preferably two integral pins. extend from the head through clearances in the blade and in the guard, the pin or pins have upset ends which are larger than the yclearances in the guard to engage the underside of the guard and lock the assembled head, blade and guard together.
Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunc-tion with the accompanying drawing, wherein:
FIGURE 1 is a side elevational View of a safety razor constructed in accordance with my invention.
FIGURE 2 is a fragmentary sectional view taken on the line 2.-2 in FIGURE 1, and showing a nal step in the method of making the razor.
FIGURE 3 is an lexploded view of the parts in section, taken on the line 2-2 in FIGURE 1, showing the pins which extend from the razor head before their ends are upset to lock the parts of the assembly together.
FIGURE 4 'is a bottom plan View of the head.
FIGURE 5 is a top plan view of the guard.
FIGURE 6 is a top plan view of the razor blade.
Referring now more particularly to the drawing, the razor is generally designated 10 and is composed of a head 12, blade 14, guard 16 and handle 18.
3,383,764 Patented May 21, 1968 ICC The head 12 is in the form of a relatively thin elongated member which is straight in longitudinal section, as will be apparent in FIGURES 2 and 3, but downwardly curved or arched transversely as shown in FIGURE 1. The head 12 has integral pins Ztl projecting downwardly from the concave undersurface thereof. The pins, before assembly ofthe razor, are cylindrical throughout their lengths, as seen in FIGURE 3, and are spaced lapart longitudinally of the head. The pins 'are located equal distances from the ends of the head and are disposed midway between the opposite side edges thereof, as will be apparent in FIG- URES l and 4.
The blade 14 may be an ordinary double-edged iiexible metal blade having the two shaving edges 22 and 24. The outline of the razor blade is similar to the outline of the head 12, as will be appreciated -by a comparison of FIGURES 4 and 6. Thus the razor blade is of thin stock and relatively long and its side and end edges will be seen to project slightly beyond the corresponding edges of the head when the parts of the razor are assembled. The binde may be similar to Athe type which is sold separately for use land replacement in the conventional safety razor, although it will be understood that the blade when used as a part of the razor herein described will -be a permanent part of the assembly and will be disposed of when the entire :assembly is thrown away.
lThe guard 16 is in the form of a relatively thin elongated member which is approximately equal in length to the head although slightly wider than the head to underlie the cutting edges of the blade when the parts of the razor are assembled. The guard is straight in longitudinal section, as seen in FIGURES 2 and 3, and arched 0r downwardly curved transversely as shown in FIGURE 1. The guard has on its underside a central downwardly extending hollow boss 2d. formed as an integral part of the guard. The boss is threaded on the inside. The end of the elongated handle 18 threads into the boss 24.
The head 12, guard 16 and handle 1S may be formed of any suitable material, but preferably are formed of an inexpensive plastic which `can be readily molded. A number of the well-known thermoplastic resins are suitable. Suitable materials are vinyl and cellulose resins. The pins 29, being integral parts of the head 12, are of course molded at the same time ras the head and formed of the same material. An inexpensive material for these parts of the razor is preferred because it is intended that the razor will be a throw-'away item. In other words, it will be used once or twice, or until the edges of the blade become dull, and then the entire razor will be thrown away. Obviously, of course, the handle 18 would not have to be thrown away since it is separable from the head, blade and guard.
The parts of the razor are shown in FIGURE 3 before assembly. It will be noted that the guard 16 has holes 26 which are spaced apart the same distance as pins 2t) and large enough to permit the pins to freely enter the holes. The blade 1d has an elongated slot or cutout portion 28 formed with generally circular portions 3) likewise spaced apart the same distance as pins 2@ and of a size to freely receive the pins. Considering FIGURES 2 and 3, the parts 12, 14 and 16 of the razor are moved together during assembly so that the blade is clamped between the head 12 and guard 16 and the pins 253 project through the openings 3) in the blade and 26 in the guard. In this condition of the parts the guard 16 underlies the head 12 and the Ablade is sandwiched between. The blade will llex, as shown in FIGURE 1, to lie in surface-tosurface relation with the opposite faces of the head and guard. Then the projecting ends of the pins are upset or flattened out to provide in eitect rivet heads 32 which are larger than the holes 26 in the guard and hence engage and underlie thc concave undersurface of thc guard to permanently secure the guard, blade and head together. The rivet heads 32 may be upset by the application of heat and pressure. The pin 34, in FIGURE 2, is a pressure applying member shown exerting sucient force against the projecting end of one of the pins to upset it and form the rivet head.
The assembly thus formed is a permanent assembly and will be thrown away after it has been used a few times. For this reason the parts of the assembly are made of inexpensive material.
What I claim as my invention is:
1. A razor comprising a head in the forni of a relatively thin elongated member, a separate guard likewise in the form of a relatively thin elongated member underlying said head member, a double-edged blade interposed and clamped between said head and guard members with the opposite cutting edges of said blade exposed along the opposite longitudinal edges of said head and guard members, means permanently securing said head member, guard member and blade together including a pair of parallel pins formed integrally with said head member and extending at right angles thereto, said pins being spaced from one another on the longitudinal center line of said head member and located equal distances from the longitudinal center of said head member, holes in said blade and guard member located on the longitudinal center line thereof and registering with said pins, said pins extending through said holes in said blade and guard member and terminating beyond said guard member, said head and guard members and pins being formed of an inexpensive, disposable thermoplastic material deformable by the application of heat and pressure, and said pins having integral, deformed and enlarged ends of greater cross section than seid holes in said guard member and engaging the side of said guard member remote from said head member to permanently secure said head member, guard member and blade together, said guard member having an integral boss on said remote side thereof disposed on the longitudinal center line thereof midway between said holes therein, and an elongated handle having one end secured to said boss and projecting from said guard member at right angles thereto.
