Description

Aug. 1, 1933. 1. B. RUEGG CLOSURE FASTENER Filed July so, 1952 A 4 0 me Patented Aug. 1, 1933 UNITED STATES PATENT OFFICE 3 Claims.

The invention aims to provide a new and improved fastener for swinging sashes, vents or other kinds of closures, and in attaining this end, a further object is to provide an advantageous resilient connection between the latch and the latch carrier which is attached to the closure, said resilient connection allowing for any slight variation in setting of the striker with which the latch cooperates and serving to give tension to l hold the sash or the like tightly closed, yet allowing leeway for variations in the sash or the like caused by shrinkage, swelling, sagging, warping, etc.

A still further object is to provide a fastener of simple and inexpensive construction, yet one which will be eflicient, reliable and long-lived.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a perspective view showing the fastener applied.

Fig. 2 is a vertical sectional View.

Fig. 3 is a view similar to Fig. 2 but showing the latch released.

Fig. 4 is a horizontal sectional view on line 4 4 of Fig. 2.

Fig. 5 is a disassembled perspective view of the casing which forms the carrier for the swingable latch.

Fig. 6 is a perspective view of the latch, the spring which holds this latch applied, and the additional springs which establish the above mentioned resilient connection between the latch and the casing.

A preferred construction has been disclosed and will be specifically described, with the understanding however that minor variations may be made within the scope of the invention as claimed.

The numeral 7 denotes a latch carrying casing of substantially rectangular form having two opposed walls 8 and 9, and two additional opposed walls l0 and 1l substantially at right angles to said walls 8 and 9, said casing being provided also with end walls 12 and with an attaching flange 13 through which screws or the like 14 may be passed to secure the casing to a sash or other closure 15. Additional, longer fasteners 16 are also passed through parts of the casing to assist in attaching said casing to the sash or the like 15. The casing wall 9 may well be separate from the other parts of the casing 55 and merely clamped between the latter and the sash or the like 15. Both this casing Wall and other portions of the casing are formed with suitable openings 17 to receive the

fasteners

14 and 16.

The casing side wall 8 is formed with a preferably rectangular opening 18 through which a substantially J-shaped latch 19 passes loosely, the curved end 20 of said latch not only constituting a handle for releasing it, but forming a cam nose for engagement with a striker 21 secured to the 65 closure frame 22, so that such engagement of cam and striker will move the latch to released position as the closure is shut, allowing the latch to snap into engagement with said striker. Preferably, this striker is in the form of an upstanding lug on an attaching plate 23, and the striker-engaging portion of the latch 19 is formed by a socket 24 in the side of said latch toward the casing wall 11.

A T-head 25 is provided for the latch 19, said T-head being confined within the casing 7. The side of this T-head toward the casing wall 8 is formed with sockets 26 in which coiled springs 27 are seated, said spring abutting said side wall 8 and serving to hold the opposite side 27 of said T-head against the casing wall 9, as seen in Fig. 2, when the latch 19 is in engagement with the striker 21. A latch spring 28 assists in holding the latch in this position, said spring being seated in a socket 29 in the head 25 and abutting the casing wall 1l. This spring forces the head 25 toward the casing side wall 10, and the latter is so shaped at 30 to constitute a fulcrum about which the head and latch may rock. Incident to rocking of the latch in releasing direction, the corner 31 of the head 25, slides upon the casing 90 side wall 9. This corner is at the side of the latch remote from the striker-engaging socket 24, and as said corner slides upon the wall 9 and the latch rocks about the fulcrum 30 in releasing direction, said latch moves in such a manner that the socket 24 moves outwardly a slight distance away from the casing 7, as shown in Fig. 3. It is thus insured that even if the closure 15 does not entirely shut, the striker 21 may at least start into the socket 24, and by then moving the latch 19 home by hand, the sash will be tightly fastened. If this movement of the latch does not draw the sash tightly closed, the springs 27 will compress to allow the final movement of the latch. These springs also allow for slight inaccuracy in locating the striker 21 and allow for various inaccuracies in the sash or the like 15, caused by shrinkage, swelling, sagging, warping, etc. It is thus insured that regardless of any minor defects which would prevent latching of conventional closure fasteners,

the present invention Will effectively operate to fasten the closure.

As above stated, the details disclosed are preferably followed, but attention is again invited to the fact that within the scope of the invention as claimed. minor variations may be made.

I claim:-

1. A closure fastener comprising a casing for attachment to the closure, said casing having two opposed walls one of which is formed with an opening, a latch passing loosely through said opening and projecting from said casing, the projecting portion of said latch having a portion at one of its sides to engage a striker, said latch having a T-head rockaoly received within the casing to allow pivotal movement of the latch, compression springs between said one wall of the casing and one side of said T-head, said springs holding the other side of said T-head against the casing side wall opposite said opening, said T-head having a corner at the side of the latch, opposite said striker-engaging portion adapted to slide upon the last mentioned casing wall when the latch is rocked in releasing direction to canse slight moven ment of said striker-engaging portion away from the casing, and spring means in said casing for normally rocking said latch in the opposite direction.

2. A ciosure fastener comprising a casing having two opposed vertical walls, one of which is formed with an opening, means for xedly securing said casing to a closure with the other of said walls disposed toward said closure, and a substantially horizontal latch extending through said opening and having a socket in its lower side to receive a striker, said latch having its outer end curved upwardly to provide both a cani nose and a handle, said cam n ose being adapted to strike the above mentioned striker to tilt the latch preparatory to reception of the striker in said socket when shutting the closure, said handle being adapted releasing the latch when opening the closure, said latch having a horizontal T--head within said casing allowing vertical swinging of the latch for engagement with and disengagement from the striker, said T-head also allowing' slight lateral swinging of said latch to insure alinement of the socket and striker.

3. A closure fastener comprising a casing having two opposed v-ei tical walis one of which is formed with an opening, in is for iixedly securing said casing to a closure th the other of said walls disposed toward said closure, a substantially horizontal ix'tending through said opening and having a socket in its lower side to receive a striker, iatch having its outer end curved upwardly to provide hoth a cam nose and a handle, said cani nose seing adapted to strike the above mentioned striker to tilt the latch preparatfwv reception of the stv :er in said socket 'when l ing the closure, handle being adapted for rele sing the iatch when opening the closure, ,i latch having a horizontal T-head within said wing vertical swinging of the latch for agement with and disengagement from the ker, T--head allowing slight lateral ffmniginfY of iatch to insure alinement of the socket f and si 'ig means engaging .Cd T--head 'i on wall of said casing and nf amally hol! i Q; said T-fhead tiitably against said v* er wall of said casing.
