BI~CKGROUND OF THE INVENTION
Field of the Invention This invention relates to end stop members f~r slide fasteners and more particularly to an elongated strip of a synthetic resin having a multiplicity of serially interconnected prospective end stop members.
Prior Art End stop members made of a plastic, most commonly thermoplastic material are usually preformed and applied directly by injection molding onto a slide fastener tape at one end thereof to form a top end stop or at the opposite end to form a bottom end stop, such end stops being adapted to limit the movement of a slider thereat to prevent the latter from moving apart from the slide fastener. Injection molding machines used in forming and applying slide fastener end stops are rather difficult to handle with respect to their thermal control and setting the end stops in respective molds, particularly where end stops are switched from one color to another entailing undue waste of time and materials.
SUMMARY OF THE INVENTION
With the foregoing drawbacks of the prior art in view, the present invention seeks to provide an elongated strip oE
a synthetic resin having a succession of interconnected end stops which can be readily cut into an individual end stop and subsequently firmly applied to a slide fastener stringer.
2~34~L~90 The invention also seeks to provide such elongated strips of various colors having a multiplicity of prospective end stops flexibly interconnected such that each strip ~an be stored conveniently separatedly in a reel or other cartridge means.
The above and other advantages and features o~ the invention will be better understood from the following detailed description taken in conjunction with the accompanying drawings which illustrate by way of example some preferred embodiments.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings and FIG. 1 in particular, there is shown a portion of an elongated strip 10 formed from a synthetic plastic material and having a succession of serially interconnected prospective end stop members 11. Adjacent end stop members 11 are spaced apart by a small distance and interconnected by a pair of flexible connecting cords 12 such as of a textile yarn thread, a synthetic plastic monoEilamënt or other flexible or pliable materials, the cords 12 extending in parallel longitudinally through opposite outer edges of the strip 10. Each of the prospective end stop members 11 has a pair of identical legs 13, 13 which are adapted to fold across the width of the strip 10 in a manner hereinafter described. Each end stop member 11 is notched from opposite ends along a central longitudinal line of the strip 10 to provide a pair of inwardly expanded oblong bights 14 confronting each other across a bridge 15 formed centrally between the legs 13, 13.
The edges 14' of each bight 14 merge with rounded-off inner , ~ `.. ~''-', ' "': ' ' " ~' , .
2V~ O
peripheral edges 13', 13' of the respective legs 13, 13.
The bridge 15 is reduced in thickness as better shown in FIG. 2 to serve as a hinge about which the end stop member 11 can be accurately and easily folded to bring the two legs 13, 13 in superimposed relation for mounting astride of a tape edge as depicted in FIG. 3, in which instance the rounded peripheral edges 13', 13' of the legs 13, 13 protrude outwardly beyond the bridge 15 as shown in FIG. 5.
As better shown in FIG. 2, the legs 13, 13 of the end stop member ll each have an arcuate groove 16 extending adjacently along their respective outer longitudinal edges and configured to fit snugly over a beaded edge 17 of a slide fastener stringer tape T which is usually cross-sectionally round, The elongated end stop forming strip lO thus constructed is cut transversely along a line 18 extending transversely across the connecting cords 12 between adjacent prospective end stop members 11 to provide an individual end stop 11'. This end stop 11' is shown attached with heat and pressure as by means of the arrangement of a supersonic horn l9 and an anvil 20 schematically shown in FIG. 4 onto a top end portion of a slide fastener stringer F which as shown in FIG. 5 comprises a support tape T and a row of coupling elements E secured thereto. Advantageously, the end stop 11' when thus attached to the support tape T is free of any sharp edge portions which tend to catch and impair a garment fabric on which the slide fastener is used. This is due to the ConStruction of the end stop 11' in which the bridge 15 about which it is folded is protected by the rounded-off peripheral edges 13', 13l of the legs 13, 13 which protrude beyond the region of the bridge 15 as better shown in FIG.
5.
Further advantageously, the prospective end stop members 11 are interconnected by the flexible connecting cords 12 which render the strip 10 flexible and supple as a whole, thus allowing a substantial length of the strip 10 to be conveniently wound on a reel 30 as depicted in FIG. 6.
A modified elongated strip lOa according to the invention is shown in FIGS. 7 and 8 and is substantially geometrically identical to the strip 10 in FIG. 1 in that each of the prospective end stop members lla comprises a pair of identical legs 13a, 13a, a pair of hights 14a, 14a, a bridge 15a and a groove 16a, except that the succession of prospective end stop members lla are interconnected by a connecting extension 21 integral with adjacent end stop members lla in lieu of the use of the flexible connecting cords 12. The connecting extension 21 extends between adjacent end stop members lla and is reduced in thickness as shown in FIG~ 8 so as to be easily cut along a transverse cut line 18a.
FIG. 9 shows a further modified form of strip lOb according to the invention which is adapted to be applied to a bottom end portion of slide fastener stringers F as shown in FIG. 10. The strip lOb has a multiplicity of , ~
Z04~L~39(~
interconnected prospective end stop members llb each of which comprises a stem 22 and a pair of upper and lower legs 13b extending laterally from opposite sides of the stem 22 and defining therebetween an arcuate groove 16b for receiving and clamping the beaded edge 17 of the stringer tape T as shown in FIG. 10. Importantly, adjacent end stop members llb are interconnected by flexible connecting cords 12b which are similar to those used in the embodiment o~
FIGS. 1 - 5 and which extend longitudinally through opposite outer edges of the strip lOb, the arrangement being that the structure of the strip 10b is rendered flexible and supple as a whole to permit a substantial length of the strip lOb to .
be reeled for convenient storage.
Obviously, various modifications and variations of the present invention are possible in the light of the above teaching. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings and FIG. 1 in particular, there is shown a portion of an elongated strip 10 formed from a synthetic plastic material and having a succession of serially interconnected prospective end stop members 11. Adjacent end stop members 11 are spaced apart by a small distance and interconnected by a pair of flexible connecting cords 12 such as of a textile yarn thread, a synthetic plastic monoEilamënt or other flexible or pliable materials, the cords 12 extending in parallel longitudinally through opposite outer edges of the strip 10. Each of the prospective end stop members 11 has a pair of identical legs 13, 13 which are adapted to fold across the width of the strip 10 in a manner hereinafter described. Each end stop member 11 is notched from opposite ends along a central longitudinal line of the strip 10 to provide a pair of inwardly expanded oblong bights 14 confronting each other across a bridge 15 formed centrally between the legs 13, 13.
The edges 14' of each bight 14 merge with rounded-off inner , ~ `.. ~''-', ' "': ' ' " ~' , .
2V~ O
peripheral edges 13', 13' of the respective legs 13, 13.
The bridge 15 is reduced in thickness as better shown in FIG. 2 to serve as a hinge about which the end stop member 11 can be accurately and easily folded to bring the two legs 13, 13 in superimposed relation for mounting astride of a tape edge as depicted in FIG. 3, in which instance the rounded peripheral edges 13', 13' of the legs 13, 13 protrude outwardly beyond the bridge 15 as shown in FIG. 5.
As better shown in FIG. 2, the legs 13, 13 of the end stop member ll each have an arcuate groove 16 extending adjacently along their respective outer longitudinal edges and configured to fit snugly over a beaded edge 17 of a slide fastener stringer tape T which is usually cross-sectionally round, The elongated end stop forming strip lO thus constructed is cut transversely along a line 18 extending transversely across the connecting cords 12 between adjacent prospective end stop members 11 to provide an individual end stop 11'. This end stop 11' is shown attached with heat and pressure as by means of the arrangement of a supersonic horn l9 and an anvil 20 schematically shown in FIG. 4 onto a top end portion of a slide fastener stringer F which as shown in FIG. 5 comprises a support tape T and a row of coupling elements E secured thereto. Advantageously, the end stop 11' when thus attached to the support tape T is free of any sharp edge portions which tend to catch and impair a garment fabric on which the slide fastener is used. This is due to the ConStruction of the end stop 11' in which the bridge 15 about which it is folded is protected by the rounded-off peripheral edges 13', 13l of the legs 13, 13 which protrude beyond the region of the bridge 15 as better shown in FIG.
5.
Further advantageously, the prospective end stop members 11 are interconnected by the flexible connecting cords 12 which render the strip 10 flexible and supple as a whole, thus allowing a substantial length of the strip 10 to be conveniently wound on a reel 30 as depicted in FIG. 6.
A modified elongated strip lOa according to the invention is shown in FIGS. 7 and 8 and is substantially geometrically identical to the strip 10 in FIG. 1 in that each of the prospective end stop members lla comprises a pair of identical legs 13a, 13a, a pair of hights 14a, 14a, a bridge 15a and a groove 16a, except that the succession of prospective end stop members lla are interconnected by a connecting extension 21 integral with adjacent end stop members lla in lieu of the use of the flexible connecting cords 12. The connecting extension 21 extends between adjacent end stop members lla and is reduced in thickness as shown in FIG~ 8 so as to be easily cut along a transverse cut line 18a.
FIG. 9 shows a further modified form of strip lOb according to the invention which is adapted to be applied to a bottom end portion of slide fastener stringers F as shown in FIG. 10. The strip lOb has a multiplicity of , ~
Z04~L~39(~
