21 Claims. (Cl. 24-205.1)

Matter enclosed in heavy brackets II] appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

The present invention relates to slide fasteners, and more particularly, to a stringer for slide fasteners.

This application is a continuation of our patent application Serial No. 714,801, filed February 12, 1958, entitled Slide Fasteners" and now abandoned, which application No. 714,801 is a division of our patent application Serial No. 617,336, filed October 22, 1956, and now abandoned.

One of the objects of the present invention is to provide a stringer for slide fasteners which may be conveniently and economically manufactured from a continuous filarnent having the properties of wire.

A further object of the invention is to provide a slide fastener stringer wherein the scoops of the stringer are composed of portions of a continuous filament having the properties of wire.

An additional object of the present invention is to provide a stringer wherein the position of the scoops with respect to the band or tape structure which carries the same remains unchanged during use.

Still another object of the invention is to provide a stringer wherein the scoops are protected from the influence of temperature changes and wherein the stringer itself may have a portion which covers the slide fastener structure.

With the above objetcs in view, the present invention consists generally of a stringer for a slide fastener, this stringer including an elongated continuous filament having the characteristics of Wire and having a zigzag configuration provided with a series of ladder-like transverse portions, all of which are substantially U-shaped at least at intermediate parts thereof so as to form scoops, and a series of longitudinal portions interconnecting the transverse filament portions which are designated herein as being the inner ends or heel portions thereof and respectively located alternately at opposite ends of the scoops, these scoops each being provided substantially at a central portion thereof with a head portion which are designated herein as being the outer ends of the transverse portions. A band means, composed at least in part of a tape, is fastened to the filament at least at parts of the inner end portions of the transverse portions of the scoops which are adjacent the longitudinal or heel portions of the filament so as to leave the heel portions at least partially exposed primarily for the purpose of permitting the flanges of the slider to move therealong and in contact therewith.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

FIG. 11 is a fragmentary perspective view showing a still further embodiment of a stringer according to the present invention, and

FIG. 12 is a fragmentary perspective view illustrating one more stringer according to the present invention as well as the process for manufacturing this stringer.

Referring now to the drawings and to FIGS. 1 and 2 in particular, in accordance with the present invention an elongated filament which has the characteristics of wire is bent into the zigzag configuration shown most clearly in FIG. 1. The filament may be a wire or it may be made of a plastic material having the characteristics of wire, such as, for example, glass, styrene, or nylon.

As is apparent from FIG. 1, the continuous filament is bent into a zigzag or meandering configuration so as to provide a series of transverse substantially parallel ladder-like portions 1 interconnected at opposite sides of the bent filament by a series of inner longitudinal heel portions 11 and 1 1' which are alternately located at opposite sides of the zigzag filament.

After the filament is formed into the zigzag configuration indicated in FIG. 1 it is placed at opposite sides thereof on a pair of flexible members, such as braids or cords 3 and 3', as shown in FIG. 1, and then the transverse portions 1 of the filament which are adjacent to the longitudinal heel portions 11 and l l are fastened to the cords 3 and 3' as by being sewn thereto with the stitches 2 and 2', respectively.

Thereafter, the transverse portions of the filament are all bent in the same direction into a substantially U- shaped configuration so as to form scoop portions 1 which are clearly illustrated in FIG. 2 substantially parallel to one another and in alignment. It will be noted that the direction of bending of the transverse filament portions is such that the cords 3 and 3' are directed toward each other and become located in the longitudinal space between the transverse portions 1 of the scoops. The tape 4 is located between the cords 3 and 3', and then the cords and tape are fastened together by means of the stitching 5, for example.

The [transverse ladderlike] U-shaped scoop portions of the filament are pressed or otherwise deformed so as to provide interlocking head portions 12 as shown in FIG. 2. It will be noted that the transverse portions 1 of the scoops are interconnected at the inner ends thereof by heel portions 11-11 [of a] having substantially U-shaped configuration so as to provide longitudinally extending base portion 10. Furthermore, it should be noted that after the filament is bent into the zigzag configuration indicated in FIG. I, the remaining steps described above may be carried out in any desired sequence. Thus, the heads 12 may be formed on the [transverse] U-shuped scoop portions of the filament at the outer ends thereof before the latter is attached to the cords 3 and 3', or after the filament is attached to the cords 3 and 3' and before the transverse filament portions are bent so as to provide the scoops. Also, it is possible to provide the heads after the scoops are formed. Also, it is possible to bend the transverse portions of the filament so as to form the scoops, and then the transverse portions of the scoops adjacent the inner ends thereof may be attached to the cords which are then attached to the tape 4 in the manner described above. It will be seen that the stitches 2 and 2' are located relatively close to the longitudinal portions 11 and 11' of the filament, so that the possibility of shifting of the scoops with respect to the cords 3 and 3' is reduced to a minimum but at the same time leaving the outer sides of these longitudinal or heel portions exposed.

Thus it will be seen that the filament is formed so as to provide two series of pairs of spaced-apart ladder-like transverse portions 1 with each pair interconnected at one end by a substantially U-shaped portion so as to provide a series of spaced-apart substantially parallel scoop portions 1' having a series of longitudinal heel portions 11-11 interconnecting the opposite end of the transverse portion of one pair only with the end of [a] the transverse [portion] portions of a preceding pair and the end of the opposed transverse portion of said pair to the end of the transverse portion of the following pair with the U-shaped portion of each of the scoops deformed centrally thereof so as to provide an interlocking head portion 12.

According to the embodiment of the invention which is shown in FIGS. 3 and 4, the filament has a rectangular configuration and is provided with the notches 13 and 13' in each of the transverse portions of the zigzag filament, as is indicated in FIG. 3, so as to provide head portions 12 therebetween this embodiment of the invention, a cord 3' is attached by the stitching 2 to one side of the zigzag filament, while the tape 4 is attached to the transverse portions at the other side of the filament, as indicated in FIG. 3. Now when the transverse filament portions are bent so as to provide the scoops, the tape 4 and the cord 3' will be located next to each other in the manner shown in FIG. 4, and these elements may be attached to each other by the stitching 5. As was pointed out above, the heads 12 may be formed on the scoops at any time after the wire has the zigzag configuration shown in FIG. 3, and furthermore it is possible to provide the scoops shown in FIG. 4 before the filament is attached to the cord and tape. Thus, with the embodiment of FIGS. 3 and 4 only one cord is required, and furthermore the

notches

13 and 13 facilitate the bending of the transverse portions of the filament so as to form the scoops which are shown in FIG. 4.

[FIGS. 5 and 6 illustrate the manner in which a pair of stringers having the construction shown in FIG. 4 cooperate with each other. In these figures, a slider 6 is shown with the scoops 1' guided between the flanges thereof for manipulating the same. The slider is provided with a wedge-shaped neck portion 61 so as to provide diverging channels within the slider body. As is apparent from FIGS. 5 and 6, the heads 12 of the scoops 1"of one stringer enter into the pockets formed by the scoops of the other stringer and interlock therewith] The embodiment of the invention which is illustrated in FIG. 7 is similar to that of FIGS. 3 and 4 except that the cord 3' and the tape 4 are joined to opposite faces of the zigzag filament. The transverse portions 1 are bent to form the scoops 1 shown in FIG. 7 in a direction which locates the cord 3 in the longitudinal space between the transverse portions of the scoops, and it will be noted that the head portions 12 of the scoops 1' of FIG. 7 have a configuration different from the head portions 12 of FIGS. 3 and 4. The tape 4 is located at the exterior of the longitudinal heel space between the longitudinal portions of the scoops, and the tape 4 may be joined to the cord 3' by suitable stitching after the scoops are formed.

According to the embodiment of the invention which is shown in FIG. 8, the tape 4 and the cord 3 are joined to the same face of the filament, as is the case with FIGS. 3 and 4, but the transverse portions 1 of the filament are bent in a direction opposite to the direction of bending shown in FIG. 4, so that with the embodiment of FIG. 8 the tape 4 and the cord 3' are located at the exterior of the stringer. It will be noted that while the intermediate heel portion of each scoop 1' of the embodiment of FIG. 8 still has a substantially U-shaped configuration, the end transverse portions of the scoops are all located substantially in a common plane and are all located between the cord 3' and the tape 4 which are joined together and which serve to join filament to the tape and cord. Furthermore, with the embodiment of FIG. 8 the right side edge of the tape 4, as viewed in FIG. 8 extends to the central portion of the transverse portions of the scoops which carry the heads, so that with this embodiment of the invention the cord 3' not only cooperates with the slider to guide the same, but in addition the slide fastener will be covered by the tapes 4. When the filament is made of certain plastic materials, it may be important to protect the filament from temperature changes, and the covering of the filament both with the tape 4 and the cord 3 in the manner shown in FIG. 8 serves to protect the filament from temperature changes.

According to the embodiment of the invention which is shown in FIG. 9, the zigzag filament which is of rectangular configuration and which is formed with the heads 12 is bent at its transverse portions 1 to form the scoops which are shown at the right portion of FIG. 9, and the tape 4 is placed in the longitudinal space between the transverse portions of the scoops while a single cord 3 is located at the exterior of the filament along the longitudinal heel portions at one side of the scoops. With this arrangement the tape 4 and the cord 3 may be joined to each other by suitable stitching and to the transverse portions 1 in a single continuous step.

FIG. 10 shows an arrangement in which the tape 4 is also located in the longitudinal space between the transverse portions 1 of the scoops, but with the embodiments of FIG. 10 the cords 3 and 3' take the form of strips of fabric which are placed at the outer faces of the transverse portions 1 of the filament, and after the tape 4 is joined to the filament by the stitches 2, the stitches 5 serve to join the

strips

3 and 3 to the tape 4. Thus, with the embodiment of FIG. 10 the filament will also be protected against temperature changes.

According to an embodiment of the invention shown in FIG. 11, no cords are used. The tape 4 is again placed in the longitudinal space between the lateral portions of the scoops, and then a series of stitches 2 are provided in order to fasten the filament to the tape 4. It will be noted that the stitches are arranged close together and substantially cover the transverse portions 1 of the scoops 1', so that the covering provided by the stitches 2 also serve to protect the filament against temperature changes. It will be noted that the stitches 2 are always located close to the longitudinal heel portions 11 and 11' of the filament so as to prevent shifting of the filament with respect to the tape and cord but leaving the outer sides of these longitudinal or heel portions exposed.

According to the embodiment of the invention shown in FIG. 12, the tape 4 is again placed in the longitudinal space between the transverse portions 1 of the scoops 1, and the stitches 2 serve to fasten the tape 4 and the transverse portions 1 of the filament together. However, in the embodiment of FIG. 12, instead of a pair of fabric strips covering the lateral portions of the filament, as indicated in FIG. 10, a single fabric strip 7 is provided, having web portions 72 and 72' which respectively are located at the outer faces of the transverse portions 1 of the filament. These strip portions 72 and 72' are interconnected by yarns or threads 71 which are exposed to an intermediate portion of the strip 7, so that yarns 71 respectively are located between the successive scoops 1, while the strip portions 72 and 72' are disposed on the outer surfaces of the transverse portions 1 of the filament and are then attached to the tape 4 by means of the stitches 5.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of slide fasteners differing from those described above.

It will also be understood that the term cord or fabric strip as herein used shall mean a substantially round or oval multiastrand twisted or woven structure, or a narrow flat ribbon or tape, or any type of stitching or any other suitable element for forming a band means along the marginal edge of the tape.

While there is shown and described an embodiment which the invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised with the scope of the invention as defined in the appended claims.
