16 Claims.
My invention relates to sliders for slide fasteners. Sliders for operating slide fasteners can be generally classed as locking or non-locking. In either type the pull tab for operating the slider is either mounted on a track or lug which projects above the slider body. This track or lug forming such projection on the slider body is objectionable not only from the standpoint of appearance, but also because such projections interfere with the pressing operation of garments and cause undue bulging in the region of the slider.
Most conventional sliders have no means provided whereby the pull tab on the slider is automatically returned to its initial position when the pull is released. For this reason the pull is free to turn up or be accidentally.. moved out of its downward position and cause difliculty in pressing a garment. The principal object therefore of my invention is to combine the advantages of a flat facedslider and automatic pulll tab return with'an effective slider locking device. In the preferred embodiment the locking means co-acts with the pull tab to return it to its initial position. The pull tab is hinged to the slider body and has means to lift the locking member out of engagement automatically when the pull is lifted for operating the slider.
In the accompanying drawing I have shown for purposes of illustration three embodiments which my invention may assume in practice and several modifications thereof.
In the drawing:
Fig. 1 is a plan view of a slider embodying my invention;
channel I 3 throughv which the fastener elements pass', and an integral neck portion I4 joining the wings. The upper wingIIl has a recess I5 and within it a second recess I6. The pull tab I 1 is of rectangular shape and adapted to lit flush with the top face of the slider body within the channel I5. The locking member I8 which is in the form of a cantilever spring ts within the second recess I and has projections I9 and 20 which extend through holes 2| and 22 in the slider body and engage the legs of the fastener elements 23. The locking member is secured to the slider body by any suitable means such as the pins or rivets 24. The pull tab has a complementary recess 44 formed on its inner side and its central portion is'reduced in thickness and terminates in a turned under cam forming portion 25. This turned under portion has a projecting lug 25 and suitable trunnions 21 are positioned to engage the holes Fig. 2 is a longitudinal cross-section through y the same;
Fig. 3 is a detail perspective view showing the pull tab;
Fig. 4 is a perspective view of the slider body with the pull tab and locking means removed.
Fig. 5 is a perspective view of one form of locking member;
Fig. 6 is a longitudinal section similar to Fig. 2 and showing the locking means in unlocked position;
Fig. '7 is a view similar to Fig. 6 and shows a modified construction;
Fig. 8 is a. longitudinal section showing anothe embodiment with the pull in closed position; and
Fig. 9 is a longitudinal section of the slider shown in Fig. 8 with the pull in operative position.
The slider illustrated comprises a body with upper and lower wings III and II, a Y-shaped 28 in lugs 4I formed near the neck end of the slider body.
As shown in Fig. 2 when the pull tab ls in vclosed position it is flush with the upper surface of the slider body. The locking member has an end portion 29 pressing against theturned under portion 25 of thepull tab. The spring in this position urges the pull tab to its downward position and insures the pull tab resting in the recess I5 at al1 times when the slider is not being operated. As shown in Fig. 6 when it is desired to move the slider the pull tab Il is raised and pivoting in the lugs III, the cams or cam forming portions 25 lift the locking prong 20 free from engagement with the fastener elements 23. At its uppermost position which is approximately 90 with respect to tl'e slider, the lug 2B on the turned under portion of the pull tab engages a slot 30 formed in the end of the locking spring and in this manner limits the amount of rotation of the pull tab.
Fig. 7 shows a similar structure but a modiiied form of locking spring. In this form the end portion 32 of the locking spring is bent to form a shoulder 33. which hooks over the projection 25 on the pull tab and limits the amount of rotation of the pull tab about its axis in the lugs 4I. When the pull tab is released the end portion 32 of the spring acting against the projection 25 of the pull tab will return the pull to its locked position within the slider channel.
Fig. 8 shows a further modification wherein the bearing lugs 34 are positioned intermediate the ends of the slider body and receive the trunnions 35 of the pull tab 35. The pull tab has a turned under portion 3l which acts against the end of the locking spring 384. As shown in Fig. 9 in this modification the travel of the pull is limited by the slider body as at 39, and in this position the locking member 38 is raised upwardly and away from engaging the fastener elements. When the pull is released in this position the' end of the locking spring 40 contacts the turned under portion 31 and returns the pull to its initial locked position within the recessed portion of the slider body.
While the first two described embodiments are satisfactory in several applications of slide fasteners, such as pants, jackets, etc., it is desirable in some instances to have a pull tab which is more centrally located on the slider body to provide easier manipulation of the slider by a pull connection in contrast with the push operation of the type of slider where the pull is hinged at the neck end. For that reason, the embodiment shown in Figs. 8 and 9 will extend the eld of usefulness of my invention without sacricing to any extent the advantages of a flat top surface.
While I have shown and described in this application three embodiments which my invention may assume in practice it will be understood that these embodiments arev for the purposes of illustration and that various other forms may be devised within the scope of my invention as set forth in the appended claims.
