Description

United States Patent O M' 3,275,362 CLASPS Martin Jacobson, Providence, RJ., assignor to Rau Findings Company, Providence, RJ., a corporation of Rhode Island Filed July 2S, 1964, Ser. No. 385,616 9 Claims. (Cl. 292-204) This invention relates to improvements in fastening devices and is more particularlarly concerned with a novel clasp having novel spring mounted latch means and of ya type especially useful for securing a flap on a hand-bag or :the like in closed position.
Purses, handbags and like articles usually are provided on the body -thereof with a clasp that includes a spring controlled latch element which is passed, while in an open or raised position, through an opening in the cover or ap and subsequently moved into .a closed or latching position to prevent withdrawal of the ap. Known types of clasp construction involve the use of separate mounting means for the latch element and the association with it of -a separate spring means operable to retain the latch in open or closed positions. Such structures have the disadvantage or requiring costly assembly operations of a multitude of parts.
In accordance with the present invention the latch element is hingedly connected directly to the spring element which in turn mounts the latch element on an attaching body. The present structure and assembly has many advantages not known to be present in prior known structures. The assembly requires a minimum of parts that are easily and quickly assembled and secured in assembled position. It is rugged in its construction.
It is :therefore an object of the invention to provide a novelly constructed clasp structure.
Another object is to provide a clasp with a novelly mounted latch element.
Another `object of the invention is to provide a clasp with a novel spring construction.
Another object is to provide a clasp with a novelly assembled latch element and spring assembly.
The structure by means of which the above noted and other .advantages and objects of the invention are attained will be described in the following specification, taken in conjunction with the yaccompanying drawings, showing a preferred illustrative embodiment of the invention, in which:
FIG. l is a perspective view of an exemplary hand bag showing the improved clasp mounted thereon.
FIG. 2 is an enlarged vertical sectional view of the clasp, taken substantially Valong lin-e 2-2 of FIG. l.
FIG. 3 is `an enlarged horizontal sectional view, taken substantially along line 3--3 of FIG 1.
FIG. 4 is a perspective View of the spring element.
Referring to the exemplary disclosure in the accompanying drawings, the clasp 11 is adapted to be mounted on the front wall 12 of .a hand bag or like article. It lincludes a mounting body 13 upon which is pivotally mounted a latch element 14 that is adapted to be extended through la hole 15 in the flap 16 of the hand bag and then pivoted approximately 90 so as to overlie the Hap and prevent it from being opened.
As best shown in FIGS. 2 and 3, the mounting body 13 is fabricated from stiff sheet metal and it includes a front wall 17 and rearwardly extending side walls 18 and end walls 19. The end walls each carry on their free edges a piercing prong 21 that is projected through the front wall 12 of the hand bag and clinched to secure the body thereto. The front wall 17 of the body is provided with a pair of longitudinally spaced openings 22.
A spring element 23 is arranged within mounting body 13 and it has its ends 24 bent normal to the plane of its Patented Sept. 27, 1966 ICC intermediate portion 25 so as to be projected outwardly one through each opening 22. Specifically, the spring `element 23, which is best shown in FIG. 4, comprises a strip of hard brass bent to provide intermediate body portion 25 and two end portions 24 bent normal thereto. Preferably, the body portion 25 is bowed rearwardly and then forwardly in the direction of the end portions to provide bowed end areas 26 and the stretch between said areas 26 is bowed rearwardly slightly as shown and has a pair of detent projections 27 therein which bear against the back face of the front wall 17. The projecting ends 24 are apertured as at 28.
The latch element 14 may be of any general overall configuration but preferably is in the form of a substantially U-shaped member yand is made of cast or stamped metal so as to be very strong and rigid. The end portions or legs 31 of the U-shaped member have a at side face 32 and are substantially `square on their terminal ends, as at 33, and each terminal is apertured, as at 34.
To assemble, the apertured legs 31 of the U-shaped latch element are matched one with each projecting end 24 of the spring, and pivot pins 35 are driven through the aligned apertures 28, 34 of each assemblyso as rto hingedly connect the latch element with the spring ends. This -assembly is such :that the spring normally urges the flat or squared surfaces 32 or 33 of the latch element firmly against the front wall 17 of body 13.
In use, the spring element 23 normally holds the latch element projected outwardly from the mounting body 13 whereupon :the latch element 14 can be projected through the hole 15 in flap 16. The latch element is thereupon swung about about the pivot pins 35. When in this position, the side faces 32 of the latch terminals bear firmly yagainst the front wall of the mounting body to secure the latch element in the folded down position shown in FIG. 1 under tension of spring element 23.
Although I have described la preferred embodiment of my invention, in considerable detail, it will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details of the structure may be modified or changed without departing from the spirit or scope of rthe invention. Accordingly, I do not desire to be restricted to the exact construction described and shown.
I claim:
1. A clasp comprising a box-like body open at its bottom and having a front wall, said front wall having spaced apertures therein, a leaf spring seated against the inside face of said front wall, end portions Ion said spring disposed normal to the main body portion thereof and extending one through each aperture, a latch element arranged outside the front wall and hingedly connected to Vthe said spring end portions, and means on said latch element to retain the latch element -in la plurality of hinged positions under :tension of said spring.
2. A clasp comprising a hollow body having a front wall `and side and end walls depending from said front wall, said fnont wall having spaced apertures therein, a leaf spring seated against the inside face of said front wall, end portions of said spring disposed normal to the main body portion thereof and extending one through each aperture, a latch element arranged outside the front Wall and hingedly connected to both of said spring end portions, and means on said latch element to retain the latch element in a plurality of pivotal positions under tension of said spring.
3. A clasp comprising a hollow body having a substantially flat front wall, said front wall having spaced apertures therein, a leaf spring disposed on the inside face of said front wall, end portions on said spring extending normal to the main portion thereof and extending t outwardly through said apertures, a latch element hingedly connected to said spring end portions, and means on the latch element to cooperate with the front wall to retain the latch element in a plurality of positions under tension of said spring. Y
4. The clasp recited in claim 3, in which the spring is bowed .away from the front wall in areas immediately adjacent to the end portions thereof.
5. The clasp recited in claim 3, in which Vthe spring has projections thereon to hold it spaced from the front wall.
6. The clasp recited in claim 3, in which thelatch element has at surfaces tocoact with the front wall.
7. A clasp comprising a latch element and a body, and spring means retained in said body and having a part thereof extending from said body swingably connected directly toI said klatch element to resiliently retain the latch element against the body and ina selected one of several positions of adjustments. 8.` In a clasp, a spring element for holding a latch in position against a supporting body comprising an elon-` gated strip `of metal having its end portions extended in a common direction normal to the general plane of the intermediate portion thereof and having means to accommodate latch-attachment means, and said intermediate portion being bowed in the direction of said end portions in areas adjacent to said end portions for `resilient engagement with the supporting body.
9; In the clasp recited in claim 8, in which 4the inter, mediate portion is bowed slightly between the bowed end areas thereof.
