Abstract
ABSTRACT OF THE DISCLOSURE
In a slide fastener having a separable end connection, as of the box-and-pin type, that includes a pin on one stringer tape and a box on the other tape at one end of the fastener, a pair of tape end reinforcements are provided which are molded integral with the pin and the box, respectively.
Each tape end reinforcement has a pair of main portions over-lying the opposite surfaces of one of the stringer tapes and integrally connected together through bridge portions extending through holes in the tape. The main portions of each reinforcement have convex edges directed toward the other end of the fastener, thus preventing the concentrated formation of wrinkles on the stringer tapes as when the fastener is opened by moving the slider down to the separable end connection.

', ~
This invention relates to slide fasteners, and in particular to slide fasteners of the type having separable end connections such as that oS the box-and-pin type. Still more particularly, the invention deals with improved tape end reinforcements for such separable slide fas~eners.
In a slide fastener having a box-and-pin separable coupling at its bottom end, for example, the bottom end portions of the stringer tapes are usually reinforced to facilitate the manipulation of the pin member of the coupling into and out of the box member through the slider, to pro-tect the tape ends against fraying or ravelling, and to protect fastener elements adjacent to the pin and the box ~- bar. According to a well known example of such tape end reinforcements, a pair of generally rectangular sheets of ; ~-~` 15 plastics or other material are secured to the respective ; tapes at slight spacings from the series of interlocking ; fastener elements thereon, the sheets having their upper edges projecting beyond the top ends of the pin and the bar.
According to another known example, each tape end reinforce-ment has an upper edge which is angled upwardly as it extends ;~ outwardly from the upper end of the pin or the bar of the separable coupling.
An objection to such prior art tape end reinforcements is that when the slider is positioned in abutting contact with the box member of the separable coupling, as upon full opening of the fastener/ the pair of stringer tapes are bent away from each other at their bottom end portions in such a way that deep wrinkles are formed in the narrow tape portions ;~

In Figs. 1 through 5 of the above drawings, the pre- -sent invention is shown adapted for a slide fastener having a separable end connection of the box-and-pin type. With particular reference to Fig. l,there are shown a pair of -- stringers 10 and 10' which include tapes 11 and 11' carrying opposed series of interlocking fastener elements or scoops .. . . .
12 and 12' on and along their inner longitudinal edges. The fastener elements 12 and 12' are shown to be of the continu-; 10 ous, helicoidal type, stitched at 13 and 13' onto the opposed edges of the stringer tapes 11 and 11' with the aid of core cords 14 and 14' passing through the turns of the respective continuous coupling elements. A slider 15, Fig. 2, is arranged on the series of fastener elements 12 and 12~ for longitudinal movement therealong to engage and disengage same, that is, to close and open the fastener, in the well ;
known manner.
The illustrated slide fastener further includes the ,;:
: box-and-pin separable end connection, generall~ designated ~` 20 16, that is disposed at the bottom end of the fastener.
Molded of synthetic resin material, the separable end connec-- tion 16 comprises a pin member 17 on the right hand stringer '.' ! .
tape 11, as viewed in the drawings, and a box member 18 form- ~-ed integral with a bar 19~ extending upwardly therefrom and ,-: , ~` 25 mounted on the left hand stringer tape 11'. The pin member 17 and the bar 19 are integrally attached not only to the . ~.i : , respective stringer tapes 11 and 11' but also ta the respec-, ., ~-- tive continuous coupling elements~

As will be eviaent from Fig. 2, the slider 15 is of the usual construction comprising a top wing (which is shown cut away except for its lateral guide flanges 20) and a bottom wing 21 which are integrally connected by a wedge-shaped neck 22 so as to define a Y-shaped guide channel therebetween for the interlocking series of fastener elements 12 and 12'. As is well known, the bottom ends of the asten~
~- er stringers 10 and 10' can be connected and disconnected as desired by manipulating the pin member 17 into and out of the socket in the box member 18 through the guide channel in the slider 15.
^ The reference numerals 23 and 23' in Figs. 1 and 2 ;~
generally denote~a pair of tape~end reinorcements in accord-ance with this invention which are o plastics molded integral with the pin member 17 and the bar 19, respectively, and ~
which are substantially lnte~grally attached to the bottom ~ -ends of the respective stringer tapes 11 and 11' as by thermal fusion or by in~ection molding. Since the paired .
~ tape end reinforcements 23 and 23i are substantially identical ; 20 in construction, only the reinforcement 23 of the right hand ,~
str1nger 10 will be described in detail, and the reference numerals used to deslgnate various parts of this reinforce-ment will be simply primed to indi~cate the corre~ponding parts of the other reinforcement 23' of the left hand stringer 10'~
As will be seen also from the sectional views given in Flgs. 3, 4 and 5, the tape end reinforcement 23 broadly comprises a pair of flat main portlons - and 25 overlying .
' ~
l~Z3Z~
. .
opposite surfaces of the stringer tape 11, and a connective portion 26 which is shown to be thinner than the main por-.
tions (Fig. 3) and which serves to inteyrally connect the main portion 24 on the front surface of the stringer tape to the pin member 17. The main portions 24 and 25 can be identical in shape and size and are themselves integrally connected together by one or more, three in the illustrated embodiment, bridge portions 27 (Fig. 4) extending through holes 28 formed in the stringer tape 11. Preferably, another bridge portion should be provided at 29 (Fig. 5) so as to extend beyond and past the extreme lower end 30 of the string-er tape 11 ~o integrally connect the main portions 24 and 25.
Each of the paired main portions 24 and 25 of the tape end reinforcement 23 has an edge 31 at its upper end which is gradually or gently convexed in the plane of each main portion, which plane is of course parallel to the plane of the stringer tape 11. As clearly indicated in Fig. 1, the convex edge 31 is connected to and extends from the top ends of the pin member 17 and the bar 19, and the crest 32 of the convex upper edge 3I of each main portion 24~25 projects upwardly beyond the upper end 33 of the pin member 17 a dis-~ .. ,. . ~.
tance D which is equal to one or more times the preselected pitch of the series of fastener elements 12. In this particular embodiment of the invention, the disdance D is approximately equal to the pitch oE the fastener elements 12, and the crest 32' of the convex upper edge 31' of each ; main portion~24'(25') of the other tape end reinforcement 23' projects upwardly beyond the upper end 33' of the bar .~:
Z3Z~
19 a distance D' which is approximately one and a half times the pitch of the fastener elements.
According to a further feature of this invention, all the corners of the main portions 24 and ~5 are rounded, as indicated at 34,35,36 and 37 in Fig. 1. Each of the main portions 24 and 25 should further have formed therein a series of openings 38 extending transversely of the fastener to permit a firm finger hold on the stringer tape 11, as for manipulating the separable end connection 16, and to permit the stringer tape to be easily stitched onto a desired article. ~
Seen at 39 is an arcuate recess formed in the outer ~ ~ ;
bottom corner of each of the main portions 24 and 25. The main reinforcement portions are so recessed because the stringer tape 11 has a hole 40 foxmed adjacent its outer bottom corner, which hole has been utilized for positioning the stringer tape during the formation of the tape end rein~
forcement 23 and other means thereon. Thus, in the case where t~le positloning hole is located farther away from the ~ -bottom end of the stringer tape, as for example at 40_ in Fig. 6, then the arcuate recesses in the main portions of the tape end reinforcament are formed in correspondingly modified positions, as shown at 39a in Fig. 6. The other details of construction of the modified pair of fastener - stringers shown in Fig. S are substantially as set forth above in connection with the embodiment of Figs. 1 ~hrough 5.
The separable slide fastener of Figs. 1 through 5 being constructed as hereinbefore described, it assumes the condition depicted in Fig. 2 when the slider 15 is moved ... . . .

portions and to the rounded corners 34,34',35,35',36,36', 37 and 37' of the main portions. As will be noted from the drawings, the bridge portions are preferably located adjacent the rounded corners of the main portions.
In Fig. 7 the tape end reinforcements of this in~ention are shown applied to a two-way separable slide fastener hav-ing a pair of sliders 15 and 42 arranged reversely to each other so that the fastener may be opened from either end.
Essentially, the separable end connection of this two-way separable slide fastener is identical with that of the box-and-pin type shown in Figs. 1 and 2 except that the box member is converted into the slider 42, so that the other parts of --the fastener are identified by the same reference characters as those used to denote the corresponding parts of the fas-tener of Figs. 1 and 2.
` It will be seen that the pair of tape end reinforce-ments 23 and 23', covering the opposite surfaces of the respective stringer tapes 11 and 11' at either ena of the fastener, are integrally connected to the pin 17 and the bar l9, respectively, of the separable end connection. The other details of construction and functions are considered self-evident from the foregoin~ description of E'igs. 1 through 6.
~hile the various objects of ~his invention as stated above are believed to have been accomplished by the specific ; ;
forms of the tape end reinforcements disclosed herein, it will be understood that they are merely for the purpose of illustration and explanation. Various changes may be made .

The fastener elements 12 and 12' are shown to be of the continu-; 10 ous, helicoidal type, stitched at 13 and 13' onto the opposed edges of the stringer tapes 11 and 11' with the aid of core cords 14 and 14' passing through the turns of the respective continuous coupling elements. A slider 15, Fig. 2, is arranged on the series of fastener elements 12 and 12~ for longitudinal movement therealong to engage and disengage same, that is, to close and open the fastener, in the well ;
known manner.
The illustrated slide fastener further includes the ,;:
: box-and-pin separable end connection, generall~ designated ~` 20 16, that is disposed at the bottom end of the fastener.
Molded of synthetic resin material, the separable end connec-- tion 16 comprises a pin member 17 on the right hand stringer '.' ! .
tape 11, as viewed in the drawings, and a box member 18 form- ~-ed integral with a bar 19~ extending upwardly therefrom and ,-: , ~` 25 mounted on the left hand stringer tape 11'. The pin member 17 and the bar 19 are integrally attached not only to the . ~.i : , respective stringer tapes 11 and 11' but also ta the respec-, ., ~-- tive continuous coupling elements~

As will be eviaent from Fig. 2, the slider 15 is of the usual construction comprising a top wing (which is shown cut away except for its lateral guide flanges 20) and a bottom wing 21 which are integrally connected by a wedge-shaped neck 22 so as to define a Y-shaped guide channel therebetween for the interlocking series of fastener elements 12 and 12'. As is well known, the bottom ends of the asten~
~- er stringers 10 and 10' can be connected and disconnected as desired by manipulating the pin member 17 into and out of the socket in the box member 18 through the guide channel in the slider 15.
^ The reference numerals 23 and 23' in Figs. 1 and 2 ;~
generally denote~a pair of tape~end reinorcements in accord-ance with this invention which are o plastics molded integral with the pin member 17 and the bar 19, respectively, and ~
which are substantially lnte~grally attached to the bottom ~ -ends of the respective stringer tapes 11 and 11' as by thermal fusion or by in~ection molding. Since the paired .
~ tape end reinforcements 23 and 23i are substantially identical ; 20 in construction, only the reinforcement 23 of the right hand ,~
str1nger 10 will be described in detail, and the reference numerals used to deslgnate various parts of this reinforce-ment will be simply primed to indi~cate the corre~ponding parts of the other reinforcement 23' of the left hand stringer 10'~
As will be seen also from the sectional views given in Flgs. 3, 4 and 5, the tape end reinforcement 23 broadly comprises a pair of flat main portlons - and 25 overlying .

. .
opposite surfaces of the stringer tape 11, and a connective portion 26 which is shown to be thinner than the main por-.
tions (Fig. 3) and which serves to inteyrally connect the main portion 24 on the front surface of the stringer tape to the pin member 17. The main portions 24 and 25 can be identical in shape and size and are themselves integrally connected together by one or more, three in the illustrated embodiment, bridge portions 27 (Fig. 4) extending through holes 28 formed in the stringer tape 11. Preferably, another bridge portion should be provided at 29 (Fig. 5) so as to extend beyond and past the extreme lower end 30 of the string-er tape 11 ~o integrally connect the main portions 24 and 25.
Each of the paired main portions 24 and 25 of the tape end reinforcement 23 has an edge 31 at its upper end which is gradually or gently convexed in the plane of each main portion, which plane is of course parallel to the plane of the stringer tape 11. As clearly indicated in Fig. 1, the convex edge 31 is connected to and extends from the top ends of the pin member 17 and the bar 19, and the crest 32 of the convex upper edge 3I of each main portion 24~25 projects upwardly beyond the upper end 33 of the pin member 17 a dis-~ .. ,. . ~.
tance D which is equal to one or more times the preselected pitch of the series of fastener elements 12. In this particular embodiment of the invention, the disdance D is approximately equal to the pitch oE the fastener elements 12, and the crest 32' of the convex upper edge 31' of each ; main portion~24'(25') of the other tape end reinforcement 23' projects upwardly beyond the upper end 33' of the bar .~:
Z3Z~
19 a distance D' which is approximately one and a half times the pitch of the fastener elements.
According to a further feature of this invention, all the corners of the main portions 24 and ~5 are rounded, as indicated at 34,35,36 and 37 in Fig. 1. Each of the main portions 24 and 25 should further have formed therein a series of openings 38 extending transversely of the fastener to permit a firm finger hold on the stringer tape 11, as for manipulating the separable end connection 16, and to permit the stringer tape to be easily stitched onto a desired article. ~
Seen at 39 is an arcuate recess formed in the outer ~ ~ ;
bottom corner of each of the main portions 24 and 25. The main reinforcement portions are so recessed because the stringer tape 11 has a hole 40 foxmed adjacent its outer bottom corner, which hole has been utilized for positioning the stringer tape during the formation of the tape end rein~
forcement 23 and other means thereon. Thus, in the case where t~le positloning hole is located farther away from the ~ -bottom end of the stringer tape, as for example at 40_ in Fig. 6, then the arcuate recesses in the main portions of the tape end reinforcament are formed in correspondingly modified positions, as shown at 39a in Fig. 6. The other details of construction of the modified pair of fastener - stringers shown in Fig. S are substantially as set forth above in connection with the embodiment of Figs. 1 ~hrough 5.
The separable slide fastener of Figs. 1 through 5 being constructed as hereinbefore described, it assumes the condition depicted in Fig. 2 when the slider 15 is moved ... . . .

portions and to the rounded corners 34,34',35,35',36,36', 37 and 37' of the main portions. As will be noted from the drawings, the bridge portions are preferably located adjacent the rounded corners of the main portions.
In Fig. 7 the tape end reinforcements of this in~ention are shown applied to a two-way separable slide fastener hav-ing a pair of sliders 15 and 42 arranged reversely to each other so that the fastener may be opened from either end.
Essentially, the separable end connection of this two-way separable slide fastener is identical with that of the box-and-pin type shown in Figs. 1 and 2 except that the box member is converted into the slider 42, so that the other parts of --the fastener are identified by the same reference characters as those used to denote the corresponding parts of the fas-tener of Figs. 1 and 2.
` It will be seen that the pair of tape end reinforce-ments 23 and 23', covering the opposite surfaces of the respective stringer tapes 11 and 11' at either ena of the fastener, are integrally connected to the pin 17 and the bar l9, respectively, of the separable end connection. The other details of construction and functions are considered self-evident from the foregoin~ description of E'igs. 1 through 6.
~hile the various objects of ~his invention as stated above are believed to have been accomplished by the specific ; ;
forms of the tape end reinforcements disclosed herein, it will be understood that they are merely for the purpose of illustration and explanation. Various changes may be made .
