Application October 12, 1955, Serial No. 540,016

1 Claim. (c1. 24405.15

This invention relates to a closure, and more particularly to a slide fastener.

The object of the invention is to provide. a slide fastener which is constructed so that the fabric or other material will not become entangledin the slide fastener during the use thereof.

Another object of the invention is to provide a slide fastener which includes a movable member that is provided with outwardly extending arms that serve to urge or bias the fabric away from the interengaging fastening elements so that the fabric will not become accidentally engaged in or entangled in the fastening elements.

A further object of the invention is to provide a slide fastener which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming 'a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a fragmentary plan view illustrating the slide fastener of the present invention.

Figure 2 is a fragmentary elevational view illustrating the slide fastener attached to the tapes but with the fabric removed.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Referring in detail to the drawings, the numeral designates each of a pair of flexible tapes, while the numeral 11 designates body portions which may be made of any suitable material such as a suitable fabric. The body portions 11 may be secured to the tapes 10 by suitable lines of stitching 12, Figure 3.

The numeral 14 designates a slider which includes an upper Wing 15 and a lower wing 16 and these wings 15 and 16 are arranged in spaced apart relation with respect to each other.

There is further provided a plurality of metal fastener elements 17 which each include an attaching portion 18 r and an interlocking portion 19.

The present invention is directed to a means for preventing the fabric from becoming accidentally entangled in the slide fastener, and this means comprises arms 20 which extend outwardly from the top wing 15. The arms 20 terminate in upstanding transversely disposed lugs or ears 21 which are adapted to engage and force away the fabric from the fastener elements. Inclined or offset sections 22 interconnect the arms 20 and wing 15 together.

Extending outwardly from the lower wing 16 are outwardly extending arms 23 which may be formed integral with the wing 16 or secured thereto through the medium of inclined sections 24.

The slider 14 is further provided with an apertured lug or ear 25, and a pull tab 26 is pivotally connected to the lug 25.

From the foregoing, it is apparent that there has been provided a slide fastener which is constructed so that the fabric will not become accidentally entangled in the interlocking parts as the slider 14 is moved back and forth by means of the pull tab 26. In use, as the slide fastener 14 is moved by means of the pull tab 26, the fastener elements 17 engage or disengage in the usual manner. However, due to the provision of the outwardly extending arms 20 and the outwardly extending arms 23 as well as the lugs 21, any fabric in the vicinity of the slide fastener will be urged away from the interfitting or interlocking parts so that the fabric will not accidentally get tangled up in the slide fastener. Thus, as shown in Figure 3 the upstanding lugs 21 engage the body portions 11 of the fabric to urge these body portions away from the interfitting parts so that the fabric 11 will be biased away from the interfitting fastening elements 17. The arms and lugs 21 serve to turn away or bias away the flexible fabric so that the filaments or fabric'will not become entangled with the slide member or the fastening elements or both. Thus, there will be no pinching or interlocking of the fabric with the fastener slide. The lugs 21 serve to spread the material away from the slide fastener.

I claim:

In a slide fastener for releasably securing together a plurality of metal fastener elements, a slider for engaging and disengaging said fastener elements and said slider comprising parallel top and bottom wings, a lug extending upwardly from said top-wing at right angles thereto, a pull tab pivotally connected to said lug, and a pair of arms extending outwardly from the top and bottom wings in opposed parallel relation to each other, the arms on the top wings terminating in vertically disposed transversely extending ears for preventing accidental engagement of fabric with the slide fastener.
