4 Claims.
This invention relates to a novel and improved form of lock sliders for separable fasteners and more particularly to automatic locking means 'for such sliders. The novel features will be best understood from the following description and the annexed drawing, in which I have shown a selected'embodiment of the invention and in which:
Fig. 1 is a perspective view of one form of slider lock construction and normally, according to the prior art, such a pull is pivoted in a fixed bearing on the top wall ll.
However, if any cessive force is applied to the stringers tending to open the fastener.
According to the present invention, I provide a spring arm, here shown as a flat spring 22, having. at its free end an arc-shaped bearing. 23 which engagesthe upper surface of the pivot 20 on the 'pull. At a point spaced from the pivot,
and preferably on the top wallof the slider ad- 1 jacent the wide end thereof, I secure the spring made according to my invention; arm to the slider, as by'providing it with a hole Fig. 2 is a side and broken sectional view of 24 through which is passeda rivet 25 which may .the device as seen in Fig. 1 illustrating the same be headed over as at 26. As plainly shown in, arranged upon parts ofstringers; the drawing, this rivet andopening are prefer r- Fig. 3 is a view similar to Fig. 2 showing parts ably elongated or non-circular so as to prevent in a different position; and rotation of the spring arm on the rivet. This Fig. 4 is a view similar to Fig. 2 showing anmeans of fastening the parts together is particother adaptation of the invention. ularly adaptable to a die cast slider, but other The invention is used with the type of sepameans may be used if found preferable. rable fastener-commonly known as a zipper and Preferably, the bearing 23 is wide enough to in which links on two stringers are coupled and 2 engage the pivot between the usual side arms 2! uncoupled by movement of a channeled slider of the-pull, although here again other arrangelengthwise of the fastener. ments may be used where found suitable.
In the construction shown in Figs. 1 to 3 in- In Fig. 4, I have shown a different embodiment elusive, l0 represents a slider body comprising a of the invention, wherein the spring 22a is protop wall II and a bottom wall l2. The walls are 25 vided with a loop 23a to substantially completely joined at the wide end of the slider by a consurround the pivot a of the pull Mia and then necting web [3 forming part of the usual dithe spring may be doubled back on itself so that verging channels at said wide end of the slider. a double thickness thereof may be secured in The top and bottom walls have inturned side place by means of the rivet 25a headed over .at flanges M to retain the links l5 of two stringers 26a. In this form,'the rivet is presumed to be Hif'il, shown in partpf Figs. 2and 3 of the drawround and then the spring arm is held against ing, against displacement and to aid in coupling rotation on the rivet as by means of one or more the links onthe stringers in the usual manner. ears 28 keyed to the slider. In the embodiment At 3 is shown a finger piece or pull which may of Fig. 4 it will also be seen that the pin lock be of the usual or any desired form of construc- 19a is nearer to the pivot than in the other embodiment and it is also shown as being'disforce is exerted on the fastener which tends to posed on the other side arm than in Fig. 1. It will also be understood, of course, that two pin locks may be used if desired, in any embodiment.
, In the embodiment shown in Figs. 1, 2, and 3, it will be seen that the spring armforcesfthe pivot against the top wall of the slider and that I made with suflicient strength to resist the normal strain on the pull caused by moving the slider by means of the pull. The spring arm,
'.WhiCh may be made of spring metal or any other suitable material, thus forms an operating means for the slider and at the same time provides a safety device which will permit the lock pin or pins to be cammed out of the slider channel or channels to prevent damage to the fastener.
The device shown in Fig. 4 will operate in the same manner as that justdescribed except that the bearing is specifically different and also the spring will be somewhat heavier because of its double thickness and thus may be used with heavier duty fasteners.
In either embodiment of the invention, the resiliency of the arm forms a means for resiliently urging the bearing towards the top wall, and so, when the stringers are pulled apart without the pull being first lifted to release the lock pin, that pin will merely ratchet over the links without causing any damage to the fastener. When the slider is operated as it should be, however, by first lifting the pull to release the lock pin, then the parts function in the normal way.
While I have shown the invention as embodied in certain specific forms, it is' to be understood that various changes may be made without departing from the scope of the invention as defined by the appended claims.
For the purposes of description, the pivot end portion of the pull may be said to comprise the pivot part proper and also means limiting the extent of the pivot, which in the construction shown comprises that part of the arms 21 which extends onto the pivot, the mounting comprising the spring, fits snugly between the limiting means of the pivot end of the pull to retain the pull against lateral displacement or movement on the slider.
I claim:
1. A slider for separable fasteners of the class described comprising a top wall having an opening therein communicating'with a channel in the slider, a pull having a lock pin adapted to pass through said opening into said channel, said pull having'bifurcated portions at one end thereof joined by a pivot, a spring arm fixed to said slider, the free end of said arm having a bearing engaging said pivot and constituting the sole 2. The combination with a slider for fastene stringers of the class described, of means form,- ing a pivotal mounting for a slider pull, said means comprising a spring member, one end portion of said member being secured to the slider, the other free yieldable end portion of said member forming a pivot bearing, a pull having a pivot end, means at said pivot end limiting the extent of the pivot portion of the pull, said spring member constituting the sole meansfor mounting the pull on the slider, and the bearing of said spring member engaging the pivot of the pull, retaining the pull against displacementlateral movement on the slider.
3. The combination with a slider for fastener stringers of the class described, of means form-' ing a pivotal mounting for a slider pull, said means comprising a spring member, one end portion of said member being secured to the slider, the other free yieldable end portion of said member forming a pivot bearing, a pull having a pivot end, means at said pivot end limiting the extent of the pivot portion of the pull, said spring member constituting the sole means for mounting the pull on the slider, the bearing of said spring member engaging the pivot of the pull, retaining the pull against displacement from the slider and also engaging thelimiting means of said pivot end to retain the pull against lateral movethe other free end portion of said member forming a pivot bearing, a pull having a pivot end,
. means at said pivot end limiting the extent of means for mounting the pull on the slider, the
width of said spring arm being such that it 00- cupies substantially the entire area on said pivot between said bifurcated portions to retain the pull against lateral movement, said spring urging 7 pressure to said loci;
the pivot portion ofthe pull, said spring member constituting the sole means for mounting the pull on the slider, the bearing of said spring member engaging the pivot of the pull, retaining the pull against displacement from the slider and also engaging th limiting means of said pivot circling the pivot of the pull.
