AUTOMATIC LOCK SLIDERS FOR SEPARABLE FASTENER STRINGERS Filed Jan. 28, 196955 57 29 4? 6 4 INVENTOR. Lou/5 H Mom/v Q W W HTTORA/EY Louis H. Morin, Bronx, N.Y. (125 Beechwood Ave, New Rochelle, NY.) Filed Jan. 23, 196i), Ser. No. 5,218 6 Claims. (Cl. 24-20514) This invention relates to sliders for use on separable fastener stringers in coupling and uncoupling said stringers. More particularly, the invention deals with what are known as automatic lock sliders having a spring actuated lock element or yoke for engaging the scoops in retaining the slider against accidental movement on the stringers. Still more particularly, the invention deals with a slider of the character described employing a shield mounted upon the web of the slider and within the pivoted portion of the lock element or yoke to house the upper portion of the spring and the spring seat in said yoke.
The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:
FIG. 1 is an enlarged side and sectional view'of a slider made according to my invention, with parts of the structure broken away.
FIG. 2 is a partial plan and sectional view of the heel end portion of the slider; and
FIG. 3 is a bracketed perspective view of the heel end portion of the slider, with the shield detached, preparatory for assemblage with the slider.
Considering FIG. 1 of the drawing, my improved slider comprises a slider body having top and bottom walls 11 and 12 joined at one end of the slider in a connecting web 13. The web 13 forms a division for the conventional channel 14 of sliders of this type and kind. The channel 14 is formed at the contracted end of the slider by inwardly extending flanges 15 and 16 on the walls 11 and 12, respectively.
In the construction shown, the web 13 includes an upwardly or outwardly projecting pivot member or post 17. The pivot member 17 has a transvers aperture 18 arranged above the wall 11 of the slider.
The top wall 11 and web 13 has, rearwardly of the member 17, a recess 19. The forward portion of the top wall 11 has an aperture 20, which opens through the end of said wall and the inner wall of the aperture is indicated at 21 in the broken away portion of the slider.
The contracted end of the wall 11 has an upwardly or outwardly extending yoke-shaped strap 22 which forms a stop, checking outward movement of a lock element or yoke 23.
The lock element 23 is in the form of a die cast bar having a downwardly offset portion 24, one end of which terminates in scoop engaging elements 25. The offset portion 24- has, at its lower end, an outwardly projecting finger 26 which operates in connection with the stop strap 22 to check outward swinging movement of the element 23 when moved outwardly by the fingerpiece pull of the slider, part of this pull being indicated at 27 in FIG. 1 of the drawing.
The other end portion of the element 23 includes side plates 28, note FIGS. 2 and 3 of the drawing, and the forward end portions of these plates terminate in rounded Walls 29, note FIG. 1, between which, and the bevelled wall 25 of one of the elements 25, a crossbar 30, forming the pivot end of the pull, operates. It will also appear that the top wall 11 of the slider has an upwardly or outwardly extending stop pin 31 which serves to check outward movement of the pivot 30 to eliminate strain in engagement of 26 with 22.
Joining the side plates 28 near the free ends thereof is a bridging portion 32, including a downwardly extending lug 33 for localizing the upper end portion of a coil spring 34 thereon. The other end portion of the spring 34 seats on the bottom wall 19 of the recess 19, as clearly illustrated in FIG. 1 in normal support of the elements 25 in operative position with scoops arranged in the channel 14 of the slider.
The upper end of the pivot member or post 17 has a pair of projecting studs 35, which extend into apertures 36, note FIG. 3, of a housing shield 37, the shield being secured in position by riveting-over the studs 35, as clearly illustrated in FIGS. 1 and 2 of the drawing. In casting the slider, the studs 35 are normally cast, as diagrammatically illustrated in FIG. 3 of the drawing, to freely receive the apertures 36 of the shield, preparatory to the riveting-over operation. This operation is performed after the yoke 23 has been attached to the pivot member 17.
The plates 28 of the yoke have inwardly extending pivot portions 38, which are normally positioned to pass freely over the member 17 and then, by applying pressure to outer surfaces of the plates, the pivot portions 38 are extended into the aperture 18 in establishing the pivotal mounting of the yoke on the member 17.
The shield 37 includes a downwardly extending end portion 39, terminating in a reduced projecting tongue 40 which seats in an aperture 41 in what may be termed the heel portion 42 of the slider body, note FIG. 3 of the drawing.
Considering FIG. 2 of the drawing, it will appear that the shield 37 fits snugly but freely within the walls 28 of the yoke 23 so as to not interfere in any way with free swinging movement of the yoke. However, it will be apparent that the bridging member 32, as well as the spring 34, will be substantially concealed.
In addition to functioning as a housing, the shield 37 performs another important function, namely preventing movement of the lock element or yoke 23 into inoperative position by any pressure which might be applied to, for example, the free end portions of the side plates 28, which would have the tendency to move the elements 25 out of engagement with the scoops of the stringer. With automatic lock sliders of the type and kind under consideration, this action has oftentimes taken place, causing accidental opening of a garment simply by pressure of another garment upon the slider. The shield acts as a check or stop resisting any such accidental movement of the lock element or yoke 23 into inoperative position. It will appear, from a consideration of FIG. 1 of the drawing, that the lock element is shown in its normal locked position and, in such position, the upper or exposed surfaces of the plates 28 are either in alinement with or within outer exposed surfaces of the shield 37.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
