2 Claims.

The present invention relates to improved zipper constructions, and has particular reference to concealed closure arrangements.

The principal object of the invention is to provide a concealed closure arrangement for a separable slide fastener, of simple and inexpensive construction.

Another object of the invention is to provide a novel tape assembly for mounting the separable fastener elements.

Still another object is to provide improved slider constructions for the concealed closure arrangements.

With the above and other objects and advantageous features in view, the invention consists of novel arrangements of parts, more fully disclosed in the detailed description following, in conjunction with the accompanying drawings,

more specifically defined in the claims appended thereto.

In the drawings, 1

Fig. i is a view of a novel tape.

Fig. 10 is a plan view, similar to Fig. l of another form of the invention.

Fig. 11 is a rear view of Fig. 10.

Fig. 12 is a section on the line i2-l 2 of Fig. 10.

Fig. 13 is a plan view, partly broken away, of still another embodiment.

Fig. 14 is a rear view of 13, the rear flap being turned.

Fig. 15 is a section on the line l5i5 of Fig. 13, and

Fig. 16 is a perspective of the slider for the embodiment of Fig. 13.

Referring to Figs. 1 to 3 of the drawings, the preferred zipper construction is designated it, and includes two complementary series it and E5 of slide fastener elements, the series being mounted on tape elements it and it, a slider It serving to selectively seal and open the slide fastener elements by manual reciprocation.

As more clearly shown in Fig. 3, each tape element has an overlap section ill, the two sections overlapping in superimposed relation to completely conceal the closure parts. This desirable result is obtained by providing a. novel tape dearound the' bead, whereby every alternate warp weave serves as a lock for the bead. With this construction, the tape is has the bead 59 extend ing entirely from one face thereof, the other face being plane, and the overlap section ll, see Figs. 5 and 8, is readily bent back to permit clamping assembly of the individual fastener elements it thereon.

The tape sections it and i2, constructed as illustrated in Fig. 8, when assembled as shown in Figs. 1, 2 and 3, completely conceal the closure parts, and the depending fastener elements permit the use of a special slider l8, see Fig. 9, which has a front plate 28, a rear plate?! in spaced relation thereto, a spreader bar 22, and a tab -23, the tab 23 being swivelly mounted on the rear plate, which has two side flanges i l, 25 to ride over the upwardly extending sides of the closure elements. The tapering formation of the plate 26 permits a smooth closing of the two overlap sections ll when the zipper is closed.

If desired, the overlap sections may be made of awidth to abut, as shown in Figs. 10 to 12, wherein the slide fastener assembly 26 has two tape assemblies 2?, 23 provided with complementary series of slide fastener elements 29, do, and a slider 3|, the tape assemblies respectively having overlaps 32, 33 which abut when the fastener elements are in closed position. With this construction the slider 3| is of conventional form at the back, but the front plate 35 is cut away at the sides to a width less than the width of the two abutting overlap sections, whereby the front plate is always beneath the overlap sections and does not bend or twist the overlap sections when the zipper is opened.

The novel tape design readily lends itself to other zipper assembly arrangements. Thus, referring to Figs. 13 to 15, the assembly 35 uses two tapes 36, 31, provided with fastener elements 38, 39 and a slide'lfl, the tapes having overlap sections 4 l, 82 which are positioned on opposite sides of the fastener elements, see Fig. 15, so .as to completely conceal both sides. With this arrangement, the slider ll! includes aback plate d3 having side flanges it, 35 to engage the bottom portions of the fastener elements, a separating or spreader bar It, and a front plate 41 which is bent in the form of a Uto embrace the upper overlap section ll, and is provided at the side with a depending flange 48 to ride over the inner edge of the overlap section, this inner edge being slightly raised by the fastener elements. A tab 49 is attached to a tab support 49a on the upper portion of the front plate 41.

The slider 40 thus includes two plate elements that slide over the fastener elements and act as slide housings for the overlap sections, thus continually aligning the overlap sections to keep the fastener elements concealed.

While I have described specific constructional embodiments of my invention, it is obvious that changes in the size, shape, and arrangements of the arts may be made to suit different slide fastener requirements, without departing from the spirit and the scope of the invention as defined in the appended claims.

I claim:

1. A slider for a slide fastener assembly, having a bottom plate member with upwardly directed side flanges, a top plate member of U-shape having upper and lower spaced parallel portions, and a spreader bar positioned between said plate members, one of said portions having a side flange extending towards the other portion, d top plate upper portion having a pull tab sup rt.

2. A slide fastener comprising a pair of tape assemblies each having a. bead extending from one surface in parallel relation to the margin thereof to provide a tape body and an overlap section, a series of cooperating slide fastener elements mounted on said beads, one overlap section extending over the upper surfaces of said series of fastener elements and the other overlap section extending over the lower surfaces thereof, and a slider device cooperating with said fastener elements to open and close the fastener, said slider element having spaced upper and lower plates and a spreader bar, said plates being respectively positioned between the fastener elements and the overlap sections, the upper plate having an auxiliary plate portion which extends over the upper overlap section, said auxiliary plate portion having a pull tab support.
