Description

June 27, 1967 A. BOUSQUET CLASP FASTENER Filed Nov. 12, 1965 p 11 v 'NTOR a I V PATEN AGENE United States Patent 3,327,362 CLASP FASTENER Andre Bousquet, Montreal, Quebec, Canada, assignor to Clix Fastener Corporation, Montreal, Quebec, (lanada Filed Nov. 12, 1965, Ser. No. 507,375 3 Claims. (Cl. 2420l) This invention relates to clasp fasteners of the twopart type.
Two part clasp fasteners are widely used for belts, garments and the like. Such a fastener usually comprises two dissimilar parts, the most common example of which is probably the hook and eye.
It is an object of the present invention to provide a clasp fastener having two identical parts, and wherein the two parts may be readily and conveniently associated with each other to provide a positive and secure fastening means but which may be easily and quickly separated for unfastening purposes.
The invention may be defined as a clasp fastener comprising two substantially identical parts, each said part comprising a unitary member having opposed side walls, a bottom wall, a top wall, a forward portion, a rearward portion, a recess extending from one to the other of said side walls said forward and rearward portions having walls diverging towards said bottom wall and defining recess, said recess having a wall joining said diverging walls and extending in an inclined direction from one of said side walls towards said bottom wall, an opening in said top wall extending inwardly from the other of said side walls and communicating with said recess, and a wall intermediate said side walls and constituting a terminating wall of said recess inclined wall and of said opening, said forward portion having a first wall surface extending in an inclined direction from said terminating wall away from said bottom wall.
The invention will be described with reference to the accompanying drawing, in which FIGURE 1 is a perspective view of one embodiment of the invention,
FIGURE 2 is a forward elevation, partly in section, of one part of the fastener,
FIGURE 3 is a side elevation of the fastener in interlocking position,
FIGURE 4 is a side elevation of the fastener in position for unlocking of the fastener parts, and
FIGURE 5 is a perspective view of a modified fastener part.
Referring to FIGURES l to 4, the fastener comprises two identical parts 10. Each part is a unitary block of, as shown, generally rectangular outline in plan. It may be formed of any suitable rigid material such as metal, plastic composition or the like.
Each part has a pair of opposed side walls 11, a bottom wall 12, a top wall 13, a forward portion 14, and a rearward portion 15. Each part also has a recess 16 extending from one to the other of side walls 11 and defined by walls 17 and 18 on the forward and rearward portions and diverging towards bottom wall 12. The recess also has a wall 19 joining diverging walls 17 and 18 and extending from one side wall 11 in an inclined direction towards bottom wall 12.
An opening 20 in top wall 13 extends inwardly from the other side wall 11 and communicates with the recess.
A wall 21 intermediate the side walls 11 constitutes a terminating wall of recess wall 19 as well as defining in part the opening 20.
Forward portion 14 has a wall surface 22 extending in an inclined direction from wall 21 and away from the bottom Wall 12.
Forward portion 14 also has a front wall surface 23 extending from bottom wall 12 in an inclined direction towards top wall 13 and in substantially parallel relation to wall 17.
A loop 24 may be mounted on rearward portions 15 for attachment to each part of the end portion of a belt indicated at 25.
It will be understood that various alternative attachment means may be provided. For instance, the clasp part 26 shown in FIGURE 5 is similar in all respects to that shown in the other figures but instead of loop 24 a groove 27 is provided in rearward portion 15 for reception of a garment edge section to which the part is fixed by clinching movement of the groove walls.
In use, one part 10 is tilted with respect to the other part It as shown in FIGURE 4, and the parts placed in laterally offset relation to each other whereby they may be slid into mating engagement to the point where walls 21 of the two parts are in engagement. Thereafter, on release of the parts, opposed tension applied thereto will place them in the interlocked position of FIGURE 3 with each inclined wall surface 22 of one part in engagement with oppositely inclined wall 19 of the other part, and wall 23 of each part in engagement with wall 18 of the other part. Disengagement of the parts cannot occur until the parts are tilted with respect to each other, as shown in FIGURE 4, and then one part moved laterally with respect to the other.
The provision of the two parts of the fastener in identical form, with each part of unitary nature, faciliates manufacturing and assembling procedures.
The convenient manner of effecting locking engagement of the parts, as well as disengagement of the parts, is an advantage in promoting use of the fastener. Furthermore, as previously indicated, when the parts are in interlocking engagement they constitute a positive fastening means.
I claim:
1. A clasp fastener comprising two substantially identical parts, each said part comprising a unitary member having opposed side walls, a bottom wall, a top wall, a forward portion, a rearward portion, a recess extending from one to the other of said side walls said forward and rearward portions having walls diverging towards said bottom wall and defining said recess, said recess having a wall joining said diverging walls and extending in an inclined direction from one of said side walls towards said bottom wall, an opening in said top wall extending inwardly from the other of said side walls and communicating with said recess, and a wall intermediate said side walls and constituting a terminating wall of said recess inclined wall and of said opening, said forward portion having a first wall surface extending in an inclined direction from said terminating wall away from said bottom wall.
2. A clasp fastener as defined in claim 1, said forward portion having a second inclined wall surface extending from said bottom wall towards said top wall and in substantially parallel relation to said diverging wall of said recess on said forward portion.
3. A clasp fastener as defined in claim 2, said parts having an interlocking position, said parts in said position having said inclined wall surface of said forward portion of each said part in engagement with said diverging wall of said rearward portion of the other of said parts, and said inclined wall of said recess of each one of said parts being in engagement with said first wall surface of said forward portion of the other of said parts.
