14 Claims. (01. 24-2055) This invention relates to slide fasteners and, in particular, to the sliders thereof.

It is an object of this invention to provide a reversible slider construction, for slide fasteners,,which slider may be operated from either side of the fastener.

It is a further object of this invention to provide such a slider constructicn'wherein opposite sides of the slider areprovided with similar pull tab supporting lugs.

It is a further object of this invention to provide detachable slide fastener pull tab constructions, particularly adapted for use on sliders of the above-described type.

These and other objects and advantages of the invention will appear from the following descriptiontaken in conjunction with the accompanying drawing which forms a part thereof, and will be pointed out in the appended claims.

In the drawing:

Fig. l is a view, in perspective, of a slide astener slider according to this invention, as applied to a slide fastener;

Fig. 2 is a side view, partly in section and partly in elevation, of the slider of Fig. 1, illustrating the manner in which the detachable pull tab member is attached thereto;

Fig. 3 is a view similar to Fig. 2, but with the pull tab partly in section;

according to Fig. 4, with a second modified form of detachable pull tab; and

Fig. 7 is a perspective view of the pull tab shown in Fig. 6 in its closed position.

,In some uses of the slide fastener and, in particular, in their use on reversible garments such as jackets, it isdesirable that the slider may be operated from opposite sides.

Heretofore, sliders have been manufactured with lugs of different type at opposite sides of the slider, and with separate pull tabs attached to each lug. In such constructions, one 01 the pull tabs was of the pin lock type and the other of the non-locking type.

In other constructions, the pull tab was mounted upon a track or retaining slide which extended from one wing or side of the slider, over the neck or wedge of the slider, and onto the other wing or side of the slider.

In the first of the.above-described constructions, the existence of a swlngable pull tab, at all times, upon the underside of the slider was extremely disadvantageous inasmuchas it was subject to catching in clothing or the skin of a.

wearer of the garment to which the slide fastener was attached and rendered the slider unit extremely bulky, unwieldy and inconvenient.

In the second of the above-described construc-' tions, the production of the track or slide which supported the pull tab was extremely costly and,

in addition, the track or slide was of such size and configuration as to catch in the clothing or skin of the wearer in the same manner as did the extra pull tab on the underside of the slider in the first-described construction, and as to im-' part to the slider unit the above-described disadvantages.

These disadvantages are totally obviated according to this invention, by forming. a slider with opposite sides or wings of similar form and provided with similar pull tab supporting lugs,

tach the pull tab from the, lug at one side of the slider and secure it, detachably to the lug at the opposite side of the slider.

Referring to the drawing in detail, the slide fastener shown in Fig. 1 comprises apair of stringers l0 and II, each formed of textile or other stringer tape l2 having one edge thereof suitably reinforced at I4 and having complementary interlocking fastener members 15 secured in suitable manner to the reinforced edge of the stringer tape H. The lower ends of the stringer tapes i0 and II are secured together by suitable known means such as the bottom stop Ha. While a regular or non-separating bottom stop is shown, it is, of course, to be understood that the principles of this invention are,

applicable to fasteners having other types of bottom stops, or separating end fittings.

The slider is generally designated l6 and comprises a pair of similar sides or wings I! connected at their upper ends by a wedge or neck l8 andprovided with marginal side flanges i9 fastener members l5 and be engaged and disengaged thereby'to open andclo se the fastener in known manner.

Each wing i1 is providedwith an upstruck lug 20 of loop form, beneath which a locking aperture, or locking pin receiving aperture 28 may,

,optionally, be provided, The wings if being similar, the apertures 2| will be similarly disposed with respect to each wing H or, in other words, as seen in Fig. 1, the aperture 2! will appear .to the right of the-upper wing ll and the lower aperture 2| will appear to the left of the lower wing ll (not shown). The lugs 28 do not project substantially from the'planes oi the wings I1, and, therefore-do not catch upon the .under garments or skin of a wearer.

Particularly adapted for use 'with the abovedescribed slider body construction isthe pull tab k shown in Figs. 1 to 3, which is generally designated 22. This pull tab is of plate-like form having the upper or. inner end bent over to form form therewith a closed loop. The hook portion .23 and leaf spring member 24 thus form clamping members ensageable with either of lugs 2@.

'One of these members is yieldable or resilient bifurcated form having a plate-like outer end portion 33, from which extends a pair of legs 36 having inwardly directed, facing, pivot projections at at their extremities. Due to the inherent resiliency of the material of the pull tab member 32, the legs 35 are normally biased outwardly of one anotherbeyond' parallelism.

The outward movement of the legs as is limited by a slidable clamping band or clamping member 85 in the form of a continuous, closed, band. This band as is adapted to rest in a pair of grooves 8? in the outer edges of the legs 36 to release the legs 3d sumciently to allow them to spread to such degree,- as shown in Fig. 5, that the ends of the projections 35 will be spaced at 1 adistance greater than the width of the lugs a hook portion 23. Fixed at one end to the un end thereofconstantly biased outwardly into engagement with the end of the hook portion 23 to ward the inner end thereof into engagement with v 4 the grooves 38, the inner ends of the legs 35 arebrought together and the projections 35 thereof are thrust into the reces'ses'or bores b and maintained therein.

Whenlt is desired to remove the pull tab 32 from one side of the slider Ito. and to attach it to the opposite side of the slider, it is merely and the other is non-yieldable; They are-maintained lnclamping position by the inherent resiliency in the resilient member-243.

' Optionally, where the slide body I6 is provided wlthapertures 2|, as above described, an upper or inner end extremity of the pull tab member 22, adjacent the hook portion 28 is bent downwardly, preferably at substantially 90 degrees from the plane of the pull tab member proper, to

. form the locking pin 25 which, in operation, will project through an aperture 2|, as shown in Fig. 3, lockingly to engage interlocking fastener members I! in the fastener member receiving channel of the slider body ll, in the flat or lowermost position of the-pull tab member 22. I

when the pull tab 22 is attached to'the lug 20 at one side of the slider l6 and where it is desired to operate, the slider from the opposite side, it is merely necessary to bring-the pull tab to the position shown in Fig. 1, press the free end of the spring member-2| toward the adjacent plate-like portion of the pull tab member 22 and then withdraw the hook portion 23 .and locking pin 25 from below the lug 20 to detach the pull tab from the slider body. 1

In order toattach the pull tab 22 to the opposite side of theslider, the pull tab is placed in the position of Fig.2 and thrust toward the slider body and then pulled downwardly of the slider body to the position of Fig. 3, whereupon the spring member 24' will automatically move outwardly to engage the hook portion 23, asv shown in Fig. 3, 'detachably to secure the pull tab 22 swingably to the slider body;

In the embodiment illustrated in Figs. 4 and 5,

the slider body liais similar to theabove-de- '7 pivot recesses or bores 20b for rotatably, or pivnecessary to thrust the clamping band 38 outwardly of the pull tab from the grooves 88, as

shown in Fig. 4, to the grooves 37, whereupon the legs will be spread, as shown in Fig. 5. The projections 35 are then aligned with the recesses orbores 20b and the clamping band thrust inwardly of the pull tab member 32' to engage- I ment with thegrooves 38 whereupon the projections 35 will be clamped in the recesses or bores 20b, as shown in Fig, 4. I

Wherelocking apertures 2| are provided, op-

tionally, as described above, one leg 34 is proingly to engage interlocking fastener members. 'IS in the channel of the slider Ila.

In the embodiment illustratedin Figs. 6 and "I. the slider body lie and its lugs 20a are similar to the above-described slider body Ito and of blade-like or plate-like members 43 pivotally connected at M by means of a rivet, or other pintle means, in such manner that they may move in the same manner as the blades of a pair ofshears. Inwardlyof the plate-like portlons of the members 43 is a pair of offset leg portions. 45 which are coplanar and which terminate in inwardly directed, facing projections 46 similar to the above-described projections 35 and cooperating with the recesses or bores 20b of the lugs 20a insimilar manner.

. Spaced from the apertures through-which the pintle means 44 extends, the upper member I; is provided with a downstruck portion 41 which I is adapted. upon alignment of the members I:

otally, receiving suitable pivot projections on a pull tab. As in the construction lllustratedin Figs. 1 to 3, the locking apertures 2| may be provided, optionally, in substantially the same loca-,

' tion in the wings I], as in the-construction of Figs. 1 to' a.

in closed position, as shown in Fig. 7, to engage a complementary downstruck portion 41 in the lower member 43.

placement of the-members 4! from the closed position when they are placed in that position,

as shown in Fig. 7. Any, suitable aperture means 48 may be provided in the plate-like portions of p This engagement of the downstruck portions ll prevents accidental disthe members 43 for alignment in the closed position to, accommodate suitable tension means. such as ribbons, thongs, or the like.

Where locking apertures II are I provided in the wings ll of the slider body I80, as describedabove, one of the leg portions 45 of the members 43 is provided with 'a locking pin member 9 which extends through one of the apertures 2|, as shown in Fig. 6, in the locked position of the slider, lockingly to engage interlocking fastener members I5 in the channel of the slider body i612.

When it is desired to remove the pull tab member 42 from one side of the slider body IM and attach it to the other side thereof, the members 43, which are locked in the position of Fig. '7, are moved pivotally apart to the position shownin Fig. 6, whereby toseparate the projections 46 thereof sufllclently to permit removal of these projections 48 from the receiving recesses or bores 20b. The pull tab member 42 is then removed from that side of the slider. It may be attached to the opposite side of the slider by reverse movement of the members 43 from the position of Fig. 6 to the position of Fig. 7 after one of the projections 46 has been aligned with the recesses or bores 20b.
