Farmington, N. Mex. Filed Jan. 29, 196i), Ser- No. 5,456 Claims. (Cl. 24-20514) This invention relates to the art of fastening devices and, more specifically, the instant invention pertains to the general field of slide fas'tening'device's. I

It is common knowledge that the conventional slider for slide fastening devices is so constructed that the outer face thereof is provided with ears, tabs, or other similar bearing projections which extend outwardly from the aforementioned face and between which is supported for pivotal movement a manually manipulative pull tongue.

The heretofore known prior art sliders are possessed of a number of distinct disadvantages among which is the fact that the projecting ears taken together with the overlying pull tongue increase, undesirably, the overall thickness of the slider, per se, causing an outward bulge of the material overlying the slider. Aside and apart from unsightly occurrence caused by the bulgedout fabric overlying the slider, the conventional slide fastening devices are also subject to criticism in that the thickness of such devices interferes, materially, with the pressing of the garment or article upon-which the slide tongue will not project beyond the plane of the outer Wall of the slider body.

A further primary object of this invention is to provide a slide fastening device incorporating in the pulltongue thereof unique means for locking the slider device against movement relative to the stringer elements when the pull tongue is moved to its locking-position.

Another object of this invention is to provide, in the slider for a slide fastening device, a pull tongue which -is pivotally connected to the slider body adjacent one end thereof and, more particularly, when the slide fastening device is incorporated in mens and womens clothing, the pull tongue will be pivotally connected to the slider body adjacent the upper end thereof.

A still'further object of this invention is to provide a slide for a .slide fastening device which is subject to inexpensive mass production, non-complex in construction and assembly and which is durable-in use.

Other and further objects and advantages of the instant invention will become more manifest from a consideration of the following specification'when read; in conjunction with the annexed drawing in which:

FIGURE 1 is a front elevational view of a slider constructed in accordance with the present-invention, the stringer tapes therefor being illustrated fragmentarily:

Referring now morespeeifically to the drawings,r'ef-- erence numeral 10 designates, in general, a slide fastener constructed in accordance with the teachings of this invention. The slide fastener includes'a pair of stringer tapes 12 having confronting edges, and to the outer longitudinally extending marginal edges of which are con;- nected the usual reassessment or teeth 14 The elemerits 14 are mounted on the tapes- 12 with the elements extending in alternating relation partially across the space intervening-between the confronting edge portions. The edge pontions'her e designated atio, carrying the fastener elements 14-, are extended within the outwardly opening sides of the slider, in the usual nianne'r. v

The slider 18-, to which the instant invention is addressed, comprises outer and

inner walls

20, 22, respectively, disposed in parallel planes (see FIGURE 2). The outer and inner walls Zil, 22, respectively, at one end portion of the slider 18, shownasthe lower end portion in FIGURES 1 to 5, inclusive, are formed with parallel side edges, with the walls remaining of constantwidtli for a part of the length of the slider body, the

walls

20, 22 thereafter progressively'increasing in width ina direction toward the opposite end of the body which constitutes the upper endof the slider as illustrated in the several figures of the drawing. v

This,jof course, is a generally conventional configuration' of' a slider body, it being understood that the tapes are interlocked where they extend out of the narrower end of the body, and are unlocked, in diverging relation, when they extend out of the wider end of thebody.

At opposite sides of the body or slide fastener 10, there are provided outwardly facing guide channels 24 for the respective edge portions 16, the channels opening on opposite sidesvof the body and also'openingthroughout their length upon the adjacent sides of the body. The {

walls

20, 22 define side walls for the channels. In ner walls or webs for the channels are defined byja ti-shaped guide structure provided in the wider end of the body between the walls 29,22, said structure comprising divergent walls 23, which walls converge, a'tj'a location medially between opposite ends of the body,

and diverge from this location toward the wider ,endgo'f thebody as is shown to particular advantage in- FIGURE 1. The walls 23 extend in laterally inwardly-spaced relation relative to the divergent portions of the sides of the body, so as to cause the channels 24 to diverge to impart a corresponding divergence to the stringer tapes where they extend out of the wider end of theslider body. The channels 24, between the point 'of. convergence of the walls 23-and the narrower extremity of the body, are in full communication with each other, sinceit 'is in this portion of the length of the body that the fastener elements 14 of the respective edge portions 16 are interlocked (see FIGURE 1).

An endwall 26, at the wider end of the body, te'rrninates at its opposite ends at the divergent extremitierof the wallsZtl, 22. 1

At the wider end of the body, the channels 24 are of where they open upon the sides of the body, through the provision of confronting longitudinal flangesformed upon opposite" sides of the

side walls

20, 22; These flangesare designated at-28, 30', respectively.

Intermediate the length of the body, the wall 20 is terminates adjacent the top wall 26'.

The side wall 20 is also stamped or otherwise formed with a transversely extending opening 34 (see FIGURE *2) across which extends a support rod 36.

fhpeassv Reference numeral 38 denotes a substantially rectangular pull tongue having a hinge barrel 40 at its upper end integrally formed therewith. As is seen in FIG-

URES

2 and 5, the hinge barrel 40 is rotatably mounted upon the support rod 36.

The pull tongue 38 extends downwardly from the sup port rod 36 for a distance below the lower ends of the

side walls

20, 22, and spaced inwardly from the lower end of the pull tongue 38 and adjacent the lower end of the side wall 20, is a transversely extending substantially rectangular slide fastener lock member 42. Referring now to FIGURES l to 3, inclusive, the lock element 42 is recessed at 44 at one end thereof providing a depending shoulder 46 at its other end.

In operation, and assuming that stringer tapes .12 are engaged within the slider 18 in the conventional manner,

'as illustrated in FIGURES l and 2, and assuming further that it is now desired to lock the slider at a given point thereon, the operator moves the pull tongue 38 from its open position shown in FIGURE 5 to its closed position shown in FIGURE 4, thereby causing the lock member 42 to extend across the fastener elements 14.

'In this construction, one of the fastener elements 14 will ;be overlapped by the cutout portion 44 of the lock member 42, and the shoulder 46 will enter between a pair of fastener elements on the other of the tapes to securely hold the tapes against relative movement with respect to each other. I

It should be noted at this point that the pull tongue 38,'when in its inoperative position, is substantially flush with the side wall 20, that is, the outer plane of the pull tongue 38 is substantially coincident with the outer plane of the side wall 20.

Reference is now made to FIGURE 6 of the drawing 'in which a second embodiment of this'invention is illustrated. To avoid repetition, elements of this second em- "bodiment of the invention finding counterparts in the first embodiment have been assigned identical reference numerals to which a prime mark has been added to clearly differentiate between the two inventions.

the structure and function of the slide 18 is identical to the slide 18 described above.

It should now be self evident that a slider 18, 18' for a slide fastener constructed in the manner described above, eliminates all unsightly bulges in fabric material lying thereabove and, at the same time, materially decreases wear on the garment or other article to which the slide fastener is-attached.

Having described and illustrated one embodiment of this invention in detail, it will be understood that the same is offered merely by way of example and that this invention is to be limited only by the scope of the ap pended claims. 7
