Description
BACKGROUND OF 1~1~ INVENTIOM
. .
Field of -the invention The present invention pertains to slide fasteners and, more particularly, to separable slide fasteners and a method of forming the same.
Descrintion of the ~rior art ;` Separable slide fasteners are conventionally utili2ed in many articles in order to permit complete separa-tion of the portions of the article carrying resp~ctive slide fastener halves. In order to form a separable slide fastener, a bottom stop for the slide fastener is conven-tionally constructed with a retainer secured to one tape thereof to prevent the slider of the slide fastener from being removed from the interengaging elements and further to receive a pin carried at the end of the other tape of the slide fastener. In order to close -the slide fastener, the slider is moved to abut the retainer and the pin is inserted through the channel in the slider and into the retainer such ~ that the slider can then be moved along the interengaging ; 20 elements to engage the same.
In forming conventional separable slide fasteners, it has been required that a retainer be specially formed and secured to the carrier tapes of the slide fastener thereby requiring precise positioning of the retainer relative to the carrier tape and the additional s~p of securing the retainer thereto.
U~ S. Patent 3,663,996 and German Patent 2,059,731 are exemplary of prior art attempts to secure a retainer to a separable slide fastener by loosely mounting the retainer :
~ 9 thereon to permit limited movement along the bottom of the slide fastener. Such pri.or art attempts, however~ still leave room for improvement, particularly, in simplifying the method for forming such slide fasteners.
SUMMARY OF THE INVENTION
The present invention i.s generally summarized in a separable slide fastener having a pair of tapes carrying interengaging elements along inner edges thereof, a slider movable along the interenga.ging elements to open and close the slide fastener, .and a separable end stop including a support member secured to one of the tapes having a head portion, a pin member secured to the other of the tapes, and a retainer in~ovably mounted on the support member having first and second opposing side walls, a partition disposed between the first and second side walls to define first and second channels in the retainer for receiving the j support member and the pin member, respectively, and means : ; in the first channel defining a pocket having a configuration mating with the configuration of the head portion of the support member to lock the head portion in the pocket.
The present invention is further generally summar-ized in a method o forming a half of a separable slide i fastener including the steps of gapping a stringer to remove .~ interengaging elements from a portion thereof, assembling a retainer on the stringer, forming a support member on the stringerj moving the reta.iner along the stringer to the .i support member, and loc~ing the retainer on the support . me~ber. -: Accordingly, it is a primary object of the present invention to overcome the disadvantages of the prior art in 31~;
forming a separable bottom stop or a slide fAsten~r by utilizing a .retainer haviny a cons-truction to permit asse~bly thereof on a stringer and movement alony -the stringer to a support member formed on the end thereof where the retainer ; S is immovably mounted on the support member.
A further object of the present invention is to ; provide a method of forming a half of a separable slide fastener by assembling a retainer on a stringer, forming a support member at the end o-f-the stringer, moving the retainer to the support member, and forcing a head portion of the support member into a pocket formed in the retainer ~ to locX the retainer on the support member.
Another object of the present invention is to con-struct a retainer for a separable slide fastener having :~
~` 15 opposing side walls with a partition therein defining first .;
and second channels for receiving a support member and a pin ~ :
member, respectively, the first channel having a pocket formed therein with a configuration mating with the confi- .
guration of a head portion of the support member to lock the 20 support member with the retainer and the second channel ~ . .
having a configuration to receive the pin member to permit closing of the slide fastener.
The present invantion has an additional object in the forming of a stop member with a wedge-shaped head -~
portion in order to facilitate àssembly of the support member with a retainer, the head portion having an end wider than the mouth of a pocket formed in the retainer such that the head portion is deformed during assembly with the retainer~
, .

Yet another object of the present invention is to construct a retainer to have a pocket therein for locking engagement with a head portion of a support member, the pocket being defined by islands extending from a pair of wings of the retainer and having ed~es contacting an inner .r side of the support member at the head portion and permit-ting slight tilting of the retainer during insert.ion of a ,~ pin member therein to close the slide fastener.
An additional object of the present invention is , : 10 to provide a retainer having a s~ider-like construction for ';.~ a separable slide fastener with a partition of the retainer having a recess formed therein to permit passage of the inter-' ; engaging elements of the slide fastener.
Some of the advantages of the present invention , over the prior art are that the retainer can be initially assembled on a stringer and then moved into locking engage-.. ~ .
ment with a support member secured to the stringer without :~
any additional securing step, the ends of the stringers of the separable slide fastener are received in the retainer so as not to extend therefrom thereby eliminating stress, the channel through the retainer is configured to permit ~ the retainer to move along the interengaging elements of the : slide fastener and the support member is constructed of a . plastic material to permit deforming thereof as the retainer :~
.~. 25 is locked on the support member.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A separable slide fastener 10 embodying the present invention, as illustrated in Figs. 1, 2 and 8, includes a pair of tapes 12 and 14 carrying filamentary interengaging elements 16 and 18, respectively, along the inner edges thereof. A slider 20 of conventional structure is captured on the interengaging elements 16 and has a Y-shaped channel therethrough such that upward movement of the slider 20 engages the interengaging elements 16 and 18 to close the slide fastener 10 and downward movement of the slider dis-engages the interengaging elements to open the slide fastener.
Top stop members 22 and 24 are carried at the top end of tapes 12 and 14, respectively, and have a shape so as not to pass through the slider 20lth~reby limiting upward closing ` movement of the slider.
-~ 30 A separating end stop is formed at the bottom of ' ~' _ 6 _, ~4L8231~i;
the slide fas-tener and is composed of a support member 26 secured to tape 12, a pin member 28 secured to tape 14 and a retainer 30 immovably mounted on the support meml~er 26.
The support men~er 26 is fonned of a shank 32 having a flat inner side 34 and a flat outer side 36 diverging a1: 38 to form a wedge-shaped head portion 40 having an end 41 wider than the shank 32. A flange 42 extends transversely from inner side 34 and has a groove 44 therein, the sides of the :Elange 42 having a width less than that of shank 32. The pin member 28 is formed of a leg 46 o:ffset to define a diverging portion 48. The leg has a :Elat outer side 50 and a flat inner side 52 from which transversely extends a tongue 54 having a width slightly less than the groove 44 formed in flange 42 of support member 26. The tongue 54 terminates at :. 15 a thickened guide tooth 56 extending transversely from the :, tongue. .
The support member 26 and the pin member 28 are each integrally formed with tape reinforcing fla ps 58 secured to tapes 12 and 14, such as by molding or ultrasonic welding.
The ends of the support member and the pin member are spaced from the terminal interengaging elements 16 and 18 carried by tapes 12 and 14, respectively, such that the guide tooth 56 can be received in the space between the end of flange 42 and the terminal interengaging element 16 carried on tape 12 and the head portion of the terminal interengaging element 16 carried by tape 12 can be received in the space between guide tooth 56 and the terminal interengaging element 18 carried by tape 14 when the slide :Eastener 10 is closedJ as illustrated in Fig. 1.
' ~1341~2~i As best shown in Figs. 3, 4, 5 and 6, the retainer 30 has a slider-like construction and inclucles wings 60 and - 62 supported in spaced, parallel relation by a partition 64.
Wing 60 has depending flanges 66 and 68 along the side edges ~:
thereof while wing 62 has similar flanges 70 and 72 extending upwardly from the side edges thereof. Flange 66 i.s aligned with flange 70 while flange 68 is aligned wi.th fl.ange 72 to :
define opposite side walls for the retainer 30. Flanges 66 and 70 are spaced to define a slot 74 extending from a top end 76 of the retainer to a bottom end 78 while flanges 68 :~
and 72 are spaced to define a slot 80 extending from top end 76 but terminating at a wall 82 jolning flanges 68 and 72 ~ :
adjacent bottom end 78 of the reta.iner. The partition 64 is disposed between the side walls of the retainer at bottom end 78 to define with flanges 66 and 70 a channel 84 in the ~ retainer and to define with flanges 68 and 72 a channel 86 .~.
;: in the retainer. The upper end 76 of the retainer is open to define with the channels 84 and 86 a Y-shaped channel in the retainer. :
The partition 64 has a flat side wall 88 extending parallel to the longitudinal axis of the retainer, and the side wall 88 has an offset portion 90 disposed at an angle .:: to the longitudinal axis of the retainer forming a wall of ; channel 86. The channel 84 is defined by a fla.t side wall .
92 of the partition 64 disposed parallel to the longitudinal :~ axis of the retainer 30 and terminating at side walls 94 and 96 angularly oriented relative to the longitudina.l a.xis of :-, the retainer to define a recess genera.lly indica.ted at 98.
The side wall 96 joins tAe side wall 90 at a rounded edge 100 8~3~
la~erally displaced Erom the longitudinal axis of the retainer. A pocket, generally indicated at 102, is formed in channel 84 and defined by bosses 104 and 106 extending laterally from side wall 92 oE the par-tition 64 and inwardly from the wings 60 and 62, respectively, along with bosses ; 108 and 110 extending laterally from Elanges 66 and 70 and inwardly from wings 60 and 62, respectively. The pocket 102 is further defined by islands 112 and 114 extending from wings 60 and 62, respectively, adjacent the recess 98 in partition 64 and protruding beyond edge 100 of the end 76 of the retainer.
The pocket 102, as defined by bosses 104, 106, 108 and 110 and islands 112 and 114, has a configuration mating with the configuration of the head portion 40 of support mem-ber 26, as best illustrated in Fig. 4, with the flaring side 38 of the head portion engaging bosses 10~ and 110 and the înner side 34 engaging the islands 112 and 114 while the ; corner of the head portion where end 41 joins side 34 is cap tured by abutment with the ends of bosses lQ4 and 106.
In order to form a separable slide fastener 10 in accordance with the present invention, a pair of slide fas-tener stringers are initially produced, such stringers each including a carrier tape with filamentary interengaging elements along the edges thereof, as illustrated in Fig. 7, wherein the stringers are given reference numbers correspond~
ing to the slide fastener as described above. Portions of the stringers are gapped and cleaned in order to remove inter~
; engaging elements therefrom as indicated at 116 on tape 12 and 118 on tape 14 in Fig. 7. The production of slide ~¢~4~36 fastener stringers usin~ filamentary interengaging elements and the gappi~g and cleaning of portions thereof is conven-tional and well known in the art; and, accordingly, no detailed description thereof follows. ~`
With the stringers gapped and cleaned, the slider l 20 is assembl~d with the interengaging elements 16 by intro-; ducing the slider at the gapped portion 116, and the retainer 30 is similarly assembled with the interengaging elements 16 by introducin~ the end 76 of the retainer at the gapped portion 116 a~d moving the retainer 30 such that the inter~
engaging elem~nts 16 pass through the channel 84 in the ratainer, the recess 98 in the partition accommodatiny the interengaging elements 16 to permit passage through the channel. Wit~ the slider 20 and the retainer 30 assembled with the stri~ger and moved along the interengaging elements away from the gapped portion 116, the tapes 12 and 14 are ~, forwarded to ~n end stop forming apparatus whereas the support member 26 and the pin member 28 of the separating bottom stop a~d the top stop members 22 and 24 are simul-taneously formed at the junctures of gapped portions I16 and 118 with interengaging elements 16 and 18, respectively, as illustrated in Fig. 8. The members 22, 24, 26 and 28 are preferably constructed of a thermally fusible plastic material and can be formed by molding to the ~ape or preforming the members and then ultrasonically fusing the members onto the tape. The techniques for the production of such stop members are well known in the art and are not described in detail - hereinafter.
With the slide fastener ~hain in the condition illustrated in Fig. 8, the stringers are cut at the gapped ~, : 10 --.. . .
-portions to separate inclividual slide fasteners and there-after the retainer 30 is moved along the interengaging ele-ments 16 to the support member 26. With the retainer in this position, sufficient force is appliecl to retainer 30 to force the end 41 of the head portion of the support member 26 through the mou-th be-tween bosses 10~, 106 and bosses 108, 110, the construction of the support member of a plastic . material permitting the head portion to deform to pass by ~ the bosses and into the pocket 102. Once the head portion : 10 is received in the pocket, it is fixedly captured due to the abutment of end 41 with the ends of bosses 104 and 106 and the mating configuration of the head portion with the pocket.
Accordingly, the retainer 30 cannot be moved either onto the interengaging elements 16 or off of the support member 26 15 and is firmly locked in place~ -With the retainer locked in place, the slider 20 can be moved down the interengaging elements 16 to abut the . end 76 of the retainar and thereafter the pin member 28 is inserted through the slider 20 and into the channel 86 until the edge of flap 58 abuts wall 82. With the pin member in this position, guide tooth 56 will be positioned between the terminal interengaging elements 16 and the end of flange 42, and the slider can be moved upward to close the slide fastener. -From the above, it will be appreciated that the method of forming half of a separable slide fastener in accordance with the present invention requires only the .
.~ assembling of the retainer on the interengaging elements of the stringer, forming the support member, moving the ,.' ' .
~4~2316 : ~ ~retainer to the support member and locking the retainer on the support member by forcing the wedge~shaped head portion of the support member through the narrower mouth o~ the pocket in the retainer to deform the support member and lock it in the pocket. To this end, it is advantageous that the retainer be formed of a relatively strong material, preferably die cast of metal, while the support mem~er is formed of a defcrmable material, preferably plastic. The wedge-shaped configuration of the head portion of the support member facilitates Eorcing of the head portion through the mouth of the pocket and further assures non--movement of the retainer relative to the support member - once the support member and retainer are interlocked.

adjacent bottom end 78 of the reta.iner. The partition 64 is disposed between the side walls of the retainer at bottom end 78 to define with flanges 66 and 70 a channel 84 in the ~ retainer and to define with flanges 68 and 72 a channel 86 .~.
;: in the retainer. The upper end 76 of the retainer is open to define with the channels 84 and 86 a Y-shaped channel in the retainer. :
The partition 64 has a flat side wall 88 extending parallel to the longitudinal axis of the retainer, and the side wall 88 has an offset portion 90 disposed at an angle .:: to the longitudinal axis of the retainer forming a wall of ; channel 86. The channel 84 is defined by a fla.t side wall .
92 of the partition 64 disposed parallel to the longitudinal :~ axis of the retainer 30 and terminating at side walls 94 and 96 angularly oriented relative to the longitudina.l a.xis of :-, the retainer to define a recess genera.lly indica.ted at 98.
The side wall 96 joins tAe side wall 90 at a rounded edge 100 8~3~
la~erally displaced Erom the longitudinal axis of the retainer. A pocket, generally indicated at 102, is formed in channel 84 and defined by bosses 104 and 106 extending laterally from side wall 92 oE the par-tition 64 and inwardly from the wings 60 and 62, respectively, along with bosses ; 108 and 110 extending laterally from Elanges 66 and 70 and inwardly from wings 60 and 62, respectively. The pocket 102 is further defined by islands 112 and 114 extending from wings 60 and 62, respectively, adjacent the recess 98 in partition 64 and protruding beyond edge 100 of the end 76 of the retainer.
The pocket 102, as defined by bosses 104, 106, 108 and 110 and islands 112 and 114, has a configuration mating with the configuration of the head portion 40 of support mem-ber 26, as best illustrated in Fig. 4, with the flaring side 38 of the head portion engaging bosses 10~ and 110 and the înner side 34 engaging the islands 112 and 114 while the ; corner of the head portion where end 41 joins side 34 is cap tured by abutment with the ends of bosses lQ4 and 106.
In order to form a separable slide fastener 10 in accordance with the present invention, a pair of slide fas-tener stringers are initially produced, such stringers each including a carrier tape with filamentary interengaging elements along the edges thereof, as illustrated in Fig. 7, wherein the stringers are given reference numbers correspond~
ing to the slide fastener as described above. Portions of the stringers are gapped and cleaned in order to remove inter~
; engaging elements therefrom as indicated at 116 on tape 12 and 118 on tape 14 in Fig. 7. The production of slide ~¢~4~36 fastener stringers usin~ filamentary interengaging elements and the gappi~g and cleaning of portions thereof is conven-tional and well known in the art; and, accordingly, no detailed description thereof follows. ~`
With the stringers gapped and cleaned, the slider l 20 is assembl~d with the interengaging elements 16 by intro-; ducing the slider at the gapped portion 116, and the retainer 30 is similarly assembled with the interengaging elements 16 by introducin~ the end 76 of the retainer at the gapped portion 116 a~d moving the retainer 30 such that the inter~
engaging elem~nts 16 pass through the channel 84 in the ratainer, the recess 98 in the partition accommodatiny the interengaging elements 16 to permit passage through the channel. Wit~ the slider 20 and the retainer 30 assembled with the stri~ger and moved along the interengaging elements away from the gapped portion 116, the tapes 12 and 14 are ~, forwarded to ~n end stop forming apparatus whereas the support member 26 and the pin member 28 of the separating bottom stop a~d the top stop members 22 and 24 are simul-taneously formed at the junctures of gapped portions I16 and 118 with interengaging elements 16 and 18, respectively, as illustrated in Fig. 8. The members 22, 24, 26 and 28 are preferably constructed of a thermally fusible plastic material and can be formed by molding to the ~ape or preforming the members and then ultrasonically fusing the members onto the tape. The techniques for the production of such stop members are well known in the art and are not described in detail - hereinafter.
With the slide fastener ~hain in the condition illustrated in Fig. 8, the stringers are cut at the gapped ~, : 10 --.. . .
-portions to separate inclividual slide fasteners and there-after the retainer 30 is moved along the interengaging ele-ments 16 to the support member 26. With the retainer in this position, sufficient force is appliecl to retainer 30 to force the end 41 of the head portion of the support member 26 through the mou-th be-tween bosses 10~, 106 and bosses 108, 110, the construction of the support member of a plastic . material permitting the head portion to deform to pass by ~ the bosses and into the pocket 102. Once the head portion : 10 is received in the pocket, it is fixedly captured due to the abutment of end 41 with the ends of bosses 104 and 106 and the mating configuration of the head portion with the pocket.
Accordingly, the retainer 30 cannot be moved either onto the interengaging elements 16 or off of the support member 26 15 and is firmly locked in place~ -With the retainer locked in place, the slider 20 can be moved down the interengaging elements 16 to abut the . end 76 of the retainar and thereafter the pin member 28 is inserted through the slider 20 and into the channel 86 until the edge of flap 58 abuts wall 82. With the pin member in this position, guide tooth 56 will be positioned between the terminal interengaging elements 16 and the end of flange 42, and the slider can be moved upward to close the slide fastener. -From the above, it will be appreciated that the method of forming half of a separable slide fastener in accordance with the present invention requires only the .
.~ assembling of the retainer on the interengaging elements of the stringer, forming the support member, moving the ,.' ' .
~4~2316 : ~ ~retainer to the support member and locking the retainer on the support member by forcing the wedge~shaped head portion of the support member through the narrower mouth o~ the pocket in the retainer to deform the support member and lock it in the pocket. To this end, it is advantageous that the retainer be formed of a relatively strong material, preferably die cast of metal, while the support mem~er is formed of a defcrmable material, preferably plastic. The wedge-shaped configuration of the head portion of the support member facilitates Eorcing of the head portion through the mouth of the pocket and further assures non--movement of the retainer relative to the support member - once the support member and retainer are interlocked.
