Definitions

  • the present invention pertains generally to slide fasteners and more particularly to the type of slide fastener commonly known as a zipper which has opposed strings or rows of interlocking elements or zipper teeth which are brought into interlocking engagement or fastened by movement of a slider in one direction along the rows and disengaged or unfastened by movement of the slider in the opposite direction.
  • a zipper which has opposed strings or rows of interlocking elements or zipper teeth which are brought into interlocking engagement or fastened by movement of a slider in one direction along the rows and disengaged or unfastened by movement of the slider in the opposite direction.
  • the present invention addresses the problem of reducing the difficulty involved with the initial engagement of the ends of a separable zipper on a jacket or similar garment, but it will be appreciated that the solution provided by the present invention has useful application to the entire field of slide fasteners without limitation to garments, which will be discussed by way of example herein.
  • the slider In the case of a typical right-handed separable zipper, the slider is installed on the right row of teeth and a socket or U-shaped member is installed on the terminal pin at the end of the right row of teeth.
  • the socket serves both as a stop for the slider and as a means for receiving the terminal pin at the end of the left row of teeth.
  • the task of initiating operation of the conventional right-handed separable zipper proceeds by inserting the left terminal pin through the left port of the slider down into the socket and then pulling the slider forward up the rows of teeth while holding the left terminal pin firmly in the socket by grasping the adjacent stringer or fabric. If the left terminal pin is not initially inserted fully into the socket, the slider will likely refuse to move forward because the teeth adjacent to the terminal pins will not be properly aligned. On the other hand, if the left terminal pin is initially inserted fully into the socket but is not held firmly in the socket, the forward movement of the slider will likely pull the left terminal pin free from the socket, thus preventing the fastening of the zipper.
  • U.S. Patent No. 2,203,005 employs separable end-connecting members which enable proper alignment of the interlocking elements or teeth for engagement by the slider and which, once properly fastened, will not pull free from each other because of the forward movement of the slider.
  • U.S. Patent No. 2,203,005 has not been adopted to any significant extent apparently because initial engagement of the specialized end-connecting members is no less difficult, if at all, in comparison with the conventional terminal pins and socket.
  • end-connecting members In order to interconnect such end-connecting members, substantial care and dexterity are required to align and engage parts that are as small or smaller than a conventional terminal pin and its associated slider port and socket terminal. Furthermore, the interengagement of such specialized end-connecting members can not be achieved while the adjoining ends of the zipper elements are substantially parallel. Rather, it is necessary that the end-connecting members first be positioned at a wide angle during insertion of a relatively small pivot pin of one end-connecting member into a slot or opening of the other end-connecting member, whereupon only then can the end-connecting members be rotated to bring the adjoining ends of the zipper elements into parallel alignment for passage through the front ports of the slider.
  • Austrian Patent Specification No. 117,965 discloses a device for connecting the ends of the zipper strings of separable zipper comprising first and second terminals each disposed at the end of the row of teeth on a respective zipper string, one of the terminals carrying the slider of the zipper when the rows of teeth are fully disengaged.
  • One terminal of the zipper is provided with an extension formed with an aperture into which a pin or post provided on the other terminal may be inserted such that when the post is inserted into the aperture formed in the extension, the extension may be rotated about the post to bring the zipper strings into alignment coupling the terminals in operative engagement.
  • German Offenlegungsschrift No. 26 05 438 discloses a zipper connection similar to that described in Austrian Patent Specification No. 117,965 wherein the terminal at the end of the zipper string is provided with an aperture to receive a member or pin provided on the terminal at the end of the other zipper string, the terminal carrying the aperture being rotatable about the pin provided on the other terminal when the pin is inserted in the aperture to bring the zipper strings into alignment.
  • the ends of the rows of teeth will then be or will readily become aligned for interengagement by the slider as it is pulled forward.
  • the cooperating or nesting portions of the terminals are relatively large, preferably at least several times larger than the size of one of the front ports of the slider, such that relatively little dexterity is required to bring the terminals into operative engagement.
  • the terminals of the present invention to separate in response to the mere forward movement of the slider during initial engagement of the rearmost ends of the rows of zipper teeth as is the case with the conventional pin-and-socket type zipper end connectors.
  • the principal advantage of the invention over prior-art separable zippers is the substantial simplification in the act of engaging the ends or terminal portions of the zipper.
  • the terminals of the present invention are sufficiently large and easy to operate such that even children who are incapable of fastening a convention pin-and-socket separable zipper can bring the terminals of the present invention into engagement properly with little attention to alignment and can pull the slider forward up the rows of zipper teeth without the risk that the terminals will pull free of each other.
  • a device for connecting the ends of a separable zipper is illustrated and designated generally by reference numeral 10.
  • the zipper includes interlocking elements or teeth arranged in adjacent rows 12 and 14 in the conventional manner along the respective edges of flexible supporting sheets or stringers 16a and 16b. Installation of the zipper in a suitable garment is achieved in a conventional manner, such as by sewing the stringers 16a and 16b to the respective right edge 18a and left edge 18b of a garment shown in phantom in FIGURES 1-3.
  • the terms "left” and “right” are used herein with reference to the point of view of a wearer of the garment.
  • the device 10 comprises a first terminal or slider base terminal 20 and a second terminal or receiving terminal 22, which terminals can be operatively engaged or brought together into working relationship in a manner similar to the operation of a conventional snap fastener such that the slider base terminal 20 is aligned over and then pressed into the receiving terminal 22 in the manner indicated.
  • the slider base terminal 20 is adapted to carry a conventional slider 24 which is manually operable by means of a handle 26 pivotally mounted in a longitudinal slot 27 atop the slider 24.
  • the slider 24 is normally carried on a base or generally disc- shaped platform 28 which, in the present example, forms an upper surface portion of the terminal 20.
  • the slider 24 includes top and bottom plates 30 and 32 held in spaced-apart parallel planes by a center post 34 which forms the leading edge of the slider 24 as it moves forwardly.
  • the slider plate 30 has downwardly extending right and left side rims 36a and 36b and the bottom slider plate 32 has upwardly extending right and left side rims 38a and 38b.
  • the rims 36a and 38a form a right side slot through which the stringer 16a passes and the rims 36b and 38b form a left side slot through which the stringer 16b passes, as is conventional in the zipper art.
  • the teeth in the opposed rows 12 and 14 enter respective right and left slider ports 39a and 39b formed between the front edges of the respective side rims and the center post 34.
  • sliding working plane is intended to mean that plane defined by the intersection of longitudinal and transverse axes of the slider 24, the longitudinal axis lying in the direction of slider movement as indicated by the dashed line L in FIGURE 2 and the transverse axis bisecting the slider ports 39a and 39b as indicated by the dashed line T in FIGURE 1 A.
  • the slider base terminal 20 includes a raised shelf 40 which serves as a guide track for slidably cooperating with the upper rims 36a and 36b so as to keep the slider 24 in general forward alignment when situated in its rearmost position thereon.
  • the platform 28 further includes a notch 42 for receiving the center post 34 of the slider 24 in the manner shown in FIGURE 1.
  • the terminal 20 includes a guide segment 44 which defines the rearmost end of the right row 12 of zipper teeth.
  • the guide segment 44 serves in the manner of a cam to guide the leading edge of the center post 34 into operative proximity with the rearmost zipper tooth 12a of the right row 12.
  • the terminal 22 includes a guide segment 46 which defines the rearmost end of the left row 14 of zipper teeth.
  • the guide segment 46 serves to guide the leading edge of the center post 34 into operative proximity with the rearmost zipper tooth 14a of the left row 14, provided the terminals 20 and 22 are operatively engaged and rotationally oriented relative to each other in the position shown. It is presently preferred that the guide segment 44 and the raised shelf 40 have a common colinear right edge 48a for a smooth transition in the movement of the slider exiting from and returning to the terminals 20 and 22.
  • the shelf 40 also preferably has a straight left edge 48b at its rearmost position and a generally S-shaped curved edge 49 leading from the edge 48b to the left edge of guide segment 44. The curved edge 49 permits a slight lateral or rotational movement of the slider 24 with respect to terminal 20 as the center post 34 of the slider 24 is guided between the guide segments 44 and 46 which tends to cause the terminals 20 and 22 to rotate slightly relative to each other.
  • the terminals 20 and 22 are engaged or nested in a manner similar to that of a snap fastener by pressing the terminals 20 and 22 together after first aligning them in the manner indicated in FIGURE 1 while the slider 24 is carried in its rearmost position on the platform 28.
  • the nesting or mating portions of the terminals 20 and 22 are preferably generally annular in shape so that the terminals 20 and 22 can be brought together without having to first align the two zipper rows 12 and 14 at any particular angle to each other as will be appreciated more fully from the description that follows.
  • the slider base terminal 20 includes curved wall 50 extending downward from the periphery of the platform 28.
  • the wall 50 preferably includes a cuff 52 projecting radially outward from a cylindrical surface 54 of the wall 50.
  • the cuff 52 is provided only through a semicircular arc around the rearward half of the cylindrical surface 54.
  • the receiving terminal 22 includes a curved mating wall 56 extending upward from the periphery of a generally circular floor 58.
  • the wall 56 preferably includes an upper interior cylindrical surface 60 of a first diameter and a lower interior cylindrical surface 62 of a second diameter, the second diameter being greater than the first diameter.
  • the wall 56 includes an upper peripheral rim 64 which with the cylindrical surface 60 defines an aperture 65 for receiving the mating wall 50 of terminal 20.
  • the terminals 20 and 22 are brought into operative engagement by first seating the cuff 52 on the upper peripheral rim 64 of the wall 56 and then pressing the terminals 20 and 22 together until the bottom of the wall 50 abuts the floor 58, which is designed to occur when the rearmost portions of the stringers 16a and 16b have become essentially coplanar with the previously defined slider working plane when the slider 24 is in its rearmost position on terminal 20.
  • the term "operative engagement" and terms of similar import are used herein to mean that the terminals 20 and 22 (and their counterparts in subsequently described embodiments) are mated or nested but not necessarily in any particular relative rotational position to each other nor are they necessarily interlocked. It will be appreciated, therefore, that the generally cylindrical construction of the terminals 20 and 22 permits them to be engaged when the adjacent ends of the zipper rows 12 and 14 are in a non- parallel orientation.
  • the cuff 52 is generally frusto- conical so that it tapers with increasing diameter in moving axially upward along the wall 50 to a maximum diameter at a generally radially oriented shelf 66 which interconnects the conical surface of the cuff 52 with the cylindrical surface 54 of the wall 50.
  • the diameter of the cylindrical surface 54 is slightly smaller than the diameter of the upper interior cylindrical surface 60 of the terminal 22, and the maximum diameter of the cuff 52 is slightly greater than the diameter of the surface 60 such that forcing the terminals 20 and 22 together causes the cuff 52 to compress slightly radially and/or causes the wall 56 to expand radially as the cuff 52 slidably passes within the surface 60.
  • the degree of compression of the cuff 52 relative to the expansion of the wall 56 depends on the properties of the materials employed in fabricating the terminals 20 and 22, a relatively rigid and resilient plastic being a preferred material.
  • a relatively rigid and resilient plastic being a preferred material.
  • the guide segments 44 and 46 can optionally be adapted to interlock with each other to further insure against inadvertent disengagement of the terminals 20 and 22, as will be described below with reference to FIGURES 3 and 4.
  • disengagement of the terminals 20 and 22 can readily be achieved when the slider 24 is situated in its rearmost position by pulling upward (in the view of FIGURE 1) on the portion of the garment hem or edge 18a adjacent to the slider base terminal 20 and simultaneously downward on the portion of the garment hem or edge 18b adjacent to the receiving terminal 22, which causes the forward portions of the terminals 20 and 22 to beging to separate since no locking action is then being provided by the unfastened zipper teeth.
  • Such pulling action on the garment edges 18a and 18b causes the terminals 20 and 22 continue to tilt out of axial alignment until the cuff 52 can slip past the shoulder 68 permitting the terminals 20 and 22 to pull free from each other.
  • the terminals 20 and 22, once engaged, are kept essentially in coaxial alignment by the relatively snug fit of the slidably abutting walls 50 and 56.
  • the mating walls 50 and 56 define circular arcs subtending angles in excess of 180 degrees so that, once engaged, the only relative movement of the terminals 20 and 22 that can occur will be rotational and not translational.
  • pulling the slider 24 forward away from the terminals 20 and 22 to fasten the zipper rows 12 and 14 will not cause terminal 20 to move forward relative to terminal 22 because the forward portions of surface 54 will abut the cooperating portions of surface 60.
  • the slider 24 is carried within the nesting portions of the terminals 20 and 22.
  • the preferred mating walls 50 and 56 are not continuous through a full 360 degrees, but are provided with gaps 69a and 69b at their forward portions to permit the slider 24 to exit from the nesting portions of the terminals 20 and 22 as it moves forward to engage the zipper rows 12 and 14.
  • One advantage of this preferred arrangement is that, while the slider 24 is carried in its rearmost position on the terminal 20, the axis of relative rotational movement of the terminals 20 and 22 passes approximately through the center of the slider 24 which is snugly encompassed within the cylinders defined by walls 50 and 56.
  • pulling forwardly on the handle 26 and rearwardly on the receiving terminal 22 will automatically cause the terminals 20 and 22 to rotate until the rows 12 and 14 are substantially parallel, whereupon the slider 24 is permitted to exit forwardly through the aligned gaps 69a and 69b in the walls 50 and 56.
  • the gaps 69a and 69b in the forward portions of the walls 50 and 56 are just slightly wider than the maximum width of the slider 24 so that it will not exit through the gaps 69a and 69b until they are perfectly aligned, thus assuring that the guide segments 44 and 46 will pass through the two front ports 39a and 39b of the slider 24 on opposite sides of the center post 34. If the terminals 20 and 22 are initially brought together with the rearmost ends of the zipper rows 12 and 14 well out of parallel, at right angles for example, then the leading edge of the center post 34, as the user pulls forwardly on the slider handle 26, will slidably bear against the cylindrical surface 60 as the terminals 20 and 22 begin to rotate into alignment. It will be appreciated that the foregoing preferred features of the device 10 permit the terminals 20 and 22 to be snapped into engagement even when the wearer is in a sitting position during which the zipper rows 12 and 14 are ordinarily misaligned.
  • a tab 70 is provided at the rear thereof for grasping, for example, between the thumb and index finger of the left hand of the wearer.
  • the provision of the slot 27 atop the slider 24 is believed to facilitate the rotational action of the terminals 20 and 22 by permitting the point of pivotal attachment of the handle 26 to the slider 24 to move forward of the axis of rotation.
  • the center post 34 slidably engages the facing surfaces of the guide segments 44 and 46 which in turn pass through the slider 24 and are brought into engagement as seen in FIGURES 2 and 3 because the interior passageway of the slider 24 narrows progressively.
  • the zipper teeth in the rows 12 and 14 are progressively brought into interlocking engagement in the conventional manner.
  • FIGURES 3 and 4 additional features of the preferred zipper terminal device 10 will be described.
  • the terminals 20 and 22 will remain locked in engagement by virtue of the insertion of a tongue 72 on guide segment 46 into a cooperating groove 74 in guide segment 44.
  • the mating of the tongue 72 and groove 74 occurs automatically with a final slight rotation of the terminals 20 and 22 as the rearmost interior surface of the left upper rim 36b of the slider 24 pushes counterclockwise on the guide segment 46 while the rearmost interior surface of the right upper rim 36a pushes clockwise on the guide segment 44.
  • the guide segment 44 preferably interlocks with the zipper tooth 14a in like manner as the various other zipper teeth of the opposed rows 12 and 14 interlock with each other.
  • the guide segment 44 includes a forwardly extending projection 76 evident in FIGURE 1, which is adapted to engage a mating indentation in the rearward portion of the zipper tooth 14a in the manner depicted in FIGURE 3.
  • the wings 80 and 82 each include top (80a, 82a) and bottom (80b, 82b) layers of a folded flange.
  • the wing 82 has a top layer 82a and a bottom layer 82b joined at a bend or fold 82c. Disposed between the layers 82a and 82b is the rearmost corner of the stringer 16b.
  • the respective wings 80 and 82 be glued to their respective stringers 16a and 16b and that the wing-stringer assemblies then be secured to their respective adjacent garment edges 18a and 18b (shown in phantom.. in FIGURE 3) by sewing. Accordingly, slotted openings 84 are provided in the wings 80 and 82, which openings register in the respective top and bottom layers of the wings 80 and 82 to permit a needle and thread (not shown) to pass therethrough.
  • the exterior faces of the wings 80 and 82 may be curved between openings 84 to facilitate guiding the point of the needle into any of the openings 84, since they are most likely obscured from view by the garment edge 18a or 18b to be attached thereat.
  • the stringers 16a and 16b are provided with beaded edges 86a and 86b, respectively, in accordance with one of several well-known prior-art techniques for securing the individual zipper teeth to the stringers 16a and 1 6b.
  • the guide segments 44 and 46 include hollow interiors for accepting the rearmost portions of the beaded edges 86a and 86b so that attachment of the wings 80 and 82 to the respective stringers 16a and 16b will automatically self-align the guide segments 44 and 46 with the respective rows 12 and 14 of zipper teeth.
  • FIGURES 1 and 4 An additional feature of the inventive device 10 which is apparent from FIGURES 1 and 4 involves the provision of an L-shaped member 88 extending forwardly from the wall 56 and the floor 58 of the terminal 22.
  • the L-shaped member 88 gives added support to the guide segment 46 and adjoining wing 82 to resist flexing at the point of attachment of the wing 82 to the rim 64 of the terminal 22.
  • the placement of the L-shaped member 88 also conveniently permits it to serve as a guide chute for the slider 24, as will be appreciated from the view of FIGURE 2.
  • FIGURES 6-8 wherein a zipper terminal device is illustrated and designated generally by reference numeral 110.
  • parts that function in a similar manner to corresponding parts in the above-described device 10 are designated using similar reference numerals.
  • the following description will focus only on the most important differences of the device 110 with respect to the above-described device 10. It will be appreciated that, while they are not shown in the similar view of FIGURE 6, the rows 12 and 14 of zipper teeth of FIGURE 1 would be provided in essentially the same manner along the beaded edges 186a and 186b of the respective stringers 11 6a and 11 6b.
  • a slider retaining mechanism comprising a spring member 190 suspended from the slider base terminal 120 so that it will lie within the interior passageway 191 of the slider 124 and retain the slider 124 in its rearmost position on the terminal 120 unless the terminals 120 and 122 are operatively engaged in the position shown in FIGURE 7.
  • the spring member 190 includes a catch 192, which extends into an opening 194 in the bottom plate 132 of the slider 124 when the spring member 190 is unflexed as shown in phantom in FIGURE 8, whereby the forward movement of the slider 124 is prevented by virtue of the catch 192 contacting a wall 196 of the bottom plate 132.
  • the spring member 190 includes an arm 198 extending through an opening 200 in a rearward portion of the wall 150 of terminal 120.
  • the slider 124 is released for forward movement by a projection 202 extending upward from a rearward portion of the wall 156 of terminal 122 to flex the spring member 190.
  • the terminal 120 preferably includes a lip 204 which extends downward from the rear of the shelf 140 in order to cover the arm 198 to prevent accidental release of the slider 124.
  • the lip 204 and the adjacent portion of terminal wall 150 form a narrow gap into which the projection 202 extends when the terminals 120 and 122 are operatively engaged, thereby pushing the arm 198 upward to flex the spring member 190 thus lifting the catch 192 out of the opening 194.
  • the upper peripheral rim of the wall 156 includes two beveled surfaces 164a and 164b which serve to guide the slider base terminal 120 down into operative engagement with the receiving terminal 122.
  • the spring flexing projection 202 extends upward from the upper beveled surface 164a to provide a curved cam surface 206 which is slidably engaged by the spring arm 198 to gradually flex the spring member 190 as the terminals 120 and 122 are rotated to bring the guide segments 144 and 146 into operative proximity.
  • the slider 124 will not be released for forward movement until the guide segments 144 and 146 are aligned for passage through the front ports of the slider 124 on opposite sides of the center post 134.
  • the arm 198 rides up along cam surface 206 to the top of the projection 202 thereby lifting the catch 192 out of the opening 194, as depicted in FIGURE 7.
  • slider 124 will not be released to exit forwardly through the gaps 169a and 169b in the walls 150 and 156 until the relative rotational position of the terminals 120 and 122 is appropriate for fastening the zipper.
  • slider 124 and slider base terminal 120 can be controlled together as a unit using the slider's handle 126, which is conveniently pivotable and longitudinally moveable within the slot 127.
  • the operation of the device 110 of FIGURES 6-8 more nearly approximates the workings of a conventional snap fastener as will be appreciated from the following description of additional features of the device 110. It will be seen from FIGURE 6 that the cuff 1 52 is coextensive with the entire periphery of the wall 150, which is disposed through an arc substantially in excess of 180 degrees.
  • the cuff 152 is guided by the beveled edges 164a and 164b through the receiving aperture 165 and down past the innermost surface 160 of terminal 122 thereby compressing the cuff 152 and/or expanding the wall 156 until the outermost edge of the cuff 152 passes beyond the surface 160, whereupon the cuff 152 and the wall 156 resiliently return to their normal dimensions.
  • terminals 120 and 122 are locked against axial movement but are free to rotate relative to each other.
  • the distance from the floor 158 to the shoulder 168 will preferably be only slightly greater than the distance from the bottom of the wall 150 to the outermost edge of the cuff 152 so that, as the bottom of the wall 150 snaps into abutment with the floor 158, the terminals 120 and 122 contemporaneously become operatively engaged and interlocked against axial movement without having to rotate the terminals 120 and 122 relative to each other.
  • the terminals 120 and 122 are readily disengaged by pulling upward on the handle 126 of the slider 124, when situated on the terminal 120, while holding down on terminal 122 with opposing forces sufficiently strong to recompress the cuff 152 and/or reexpand the wall 156 until the cuff 152 can again pass within the surface 160.
  • the cuff 152 is provided with a curved upper edge 166 for reducing the force required to pull the terminals 120 and 122 apart.
  • the slider base terminal (20 or 120) is snapped into engagement with its receiving terminal (22 or 122), whereas the mode of release employed by device 10 differs somewhat from that employed by device 110.
  • the terminals 20 and 22 are disengaged by tilting them out of coaxial alignment by forcing their forward portions apart until the cuff 52 of terminal 20 can be withdrawn from beneath the shoulder 68 at the rearward portion of terminal 22.
  • the terminals 120 and 122 are snapped out of engagement while generally maintaining the terminals 120 and 122 in coaxial alignment.
  • Such snap-release is achieved by grasping the slider handle 126 or the wing 180 with one hand and the wing 182 with the other hand and pulling in opposite directions.
  • the disengagement of the respective terminals of devices 10 and 110 requires no special concentration or dexterity.
  • the respective terminals readily and automatically release from each other in response to moderate forces tending to pull them apart.
  • the snap-release action of the terminals 120 and 122 tends to apply slightly more stress to the wing 182 of device 110 than is applied to the wing 82 of device 10.
  • the L-shaped member 188 is preferably permanently secured to the lower wing plate 182b for added support.
  • FIGURES 9-15 In the following description of several additional embodiments of the invention illustrated in FIGURES 9-15, it will be appreciated that the zipper teeth and associated stringers, which are not shown, can be attached to the terminals in the same manner as with the first embodiment of the invention shown in FIGURES 1-5. It will also be appreciated that the wings (380, 382, 480, 482, 580, 582) and guide segments (344, 346, 444, 446, 544, 546), which are merely shown schematically as solid members in FIGURES 9-15, preferably have provisions for receiving the stringers in a manner similar to that depicted in FIGURE 4.
  • FIGURE 9 A third embodiment of the invention will now be described with reference to FIGURES 9 and 10 wherein parts that function in a similar manner to previously described parts are designated using similar reference numerals.
  • the slider 324 is carried above the platform 328 of the slider base terminal 320.
  • This arrangement eliminates the need for a gap in the wall 350 as is required in the first two embodiments of the invention in which the slider is carried partially within the nesting portion of its slider base terminal.
  • the mating wall 356 of the receiving terminal 322 of FIGURE 10 is provided through a complete 360° arc or ring.
  • the slider 324 is carried in its rearmost position above and entirely outside of the nesting portions defined by the annular walls 350 and 356 of the terminals 320 and 322.
  • the structural simplicity of this third embodiment of the invention makes it comparatively less expensive to fabricate.
  • the slider 324 is held in proper alignment when in its rearmost position on the slider base ter- - minal 320 by means of a guide track 340, which is affixed atop the platform 328, and cooperating L-shaped flanges 341 a and 341 b, which extend downward from the bottom of the slider 324.
  • the guide track 340 appears generally T-shaped in the view of FIGURE 9 and preferably tapers to a pointed forward end in the manner of guide track 440 to be described below in conjunction with FIGURE 11.
  • the terminals 320 and 322 are adapted to be snapped into engagement by merely pressing the slider base terminal 320 down through the receiving aperture 365 and into the terminal 322.
  • the wall 350 of terminal 320 has an outwardly curved peripheral surface 366 which abuts a cooperating recess or indented surface 368 along the interior of the wall 356 of terminal 322.
  • the interior dimension of the upper bevelled rim 364 of terminal 322 and the cooperating portions of the wall 350 of terminal 320 are adapted so that the wall 350 will contract slightly and/or the wall 356 will expand slightly so as to allow the engagement of the terminals 320 and 322.
  • the terminals 320 and 322 When engaged, however, the terminals 320 and 322 are essentially free to rotate relative to each other so that the guide segment 346 can be positioned to pass into the left front slider port 339b just to the left of the center post 334.
  • the guide segment 346 is supported over and just forward from the rim 364 by means of the wing 382 which in turn cantilevers from its L-shaped supporting wall 388.
  • FIGURES 11-13 A fourth embodiment of the invention will now be described with reference to FIGURES 11-13 wherein parts that function in a similar manner to previously described parts are designated using similar reference numerals.
  • the slider 424 (partially visible in phantom in FIGURES 12 and 13) is held in proper orientation on the slider base terminal 420 by means of a guide track 440 (seen in FIGURE 11) which cooperates with flanges (not shown) on the bottom of the slider 424 in a similar manner to the guide track 340 and flanges 341 a and 341 b of the previously described embodiment as illustrated in FIGURE 9.
  • a rim 443 To the rear of the guide track 440 is a rim 443 which serves as a stop for the slider 424.
  • the slider 424 is supported in its rearmost position on a platform 428 above and entirely outside of the nesting portions of the terminals 420 and 422, as will be apparent from FIGURES 11 and 12.
  • the wings 480 and 482 and guide segments 444 and 446 are therefore supported above the plane of the platform 428, the wing 480 cantilevering from a supporting shelf 445 and the wing 482 cantilevering from an L-shaped supporting wall 488.
  • the slider base terminal 420 includes spiral- shaped bottom walls or surfaces 450a and 450b which are adapted to slidably abut complementary walls or surfaces 456a and 456b of the receiving terminal 422 during engagement of the terminals 420 and 422.
  • the generally cone- like arrangement of the terminals 420 and 422 greatly facilitates guiding them into operative engagement.
  • the receiving aperture 456 defined by the upper peripheral rim 464 of terminal 422 provides an easy target for the bottom portion of terminal 420.
  • the dual-spiral construction of the cooperating surfaces of the terminals 420 and 422 tends to promote rotation in the proper direction for interlocking the terminals 420 and 422 merely by the force of pressing the terminals 420 and 422 together.
  • a zipper terminal device 510 in accordance with a fifth embodiment of the invention will now be described with reference to FIGURES 14-16 wherein parts that function in a similar manner to previously described parts are designated using similar reference numerals.
  • the slider employed in this embodiment is illustrated by the phantom outline 524 in FIGURE 14. When in its rearmost position as shown, the slider 524 is carried forward and entirely outside of the nesting portions of the terminal 520 and 522.
  • the slider base terminal 520 is provided with guiding and retaining walls 540 which provide a slider receptacle on both sides of a central web 528.
  • the web 528 is inserted between the plates of the slider 524 in a manner similar to the way in which the platform 28 is inserted between the plates 30 and 32 of the slider 24 of FIGURE 1.
  • the slider 524 is held in proper alignment by the walls 540 with the center post 534 of the slider 524 resting in a notch 542 in the web 528.
  • the slider base terminal 520 includes a raised annular portion 550 adapted to mate with an annular recessed portion 556 of the receiving terminal 522.
  • the nesting or mating portions of the terminals 520 and 522 include peripheral rims 566 and 568, respectively, which operate in the manner of a snap fastener to hold the terminals 520 and 522 in operative engagement while permitting relative rotational movement thereof.
  • the operation of the device 510 proceeds as follows. With the slider 524 in its rearmost position on the terminal 520 as depicted in FIGURE 14, the terminals 520 and 522 are pressed or snapped into operative engagement as seen best in the view of FIGURE 15.
  • the exterior faces of the terminals 520 and 522 are provided with shallow recesses 551 and 557 to facilitate grasping the respective annular nesting portions 550 and 556 between the thumb and index finger of the user while snapping the terminals 520 and 522 into engagement.
  • the terminal 522 is rotated slightly counterclockwise with respect to the terminal 520 to the approximate position seen in FIGURE 14 wherein the guide segment 546 has become aligned for passage through the respective front port of the slider 524.
  • the guide segment 544 preferably includes a tongue portion 572 which fits into a cooperating groove 574 in the guide segment 546 as seen best in FIGURE 15, thereby interlocking the front portions of the terminals 520 and 522 when the zipper teeth (not shown) are fastened.
  • an inner edge 583 of the wing 582 can be nested within a cooperating groove 585 in the adjacent edge of the terminal 520.
  • the edge 583 is shown in the position just prior to its entering the groove 585.
  • the edge 583 can be extended down around the upper periphery of the adjoining annular nesting portion 556 to interlock with a cooperating portion of the groove 585 as seen best in FIGURE 15.
  • the nesting portions 550 and 556 are relatively large compared to the conventional terminal pin (not shown) which would be used with the slider 524 in a conventional pin-and-socket separable zipper.
  • the diameter of the receiving aperture 565 (shown in dotted outline) of the nesting portion 556 is approximately equal to the width of the slider 524. It will be appreciated, therefore, that the area of the receiving aperture 565 is several times larger than the area of one of the slider ports. Accordingly, aligning and engaging the nesting portions 550 and 556 of the terminals 520 and 522 is significantly easier than the act of feeding a terminal pin (not shown) into the respective front slider port in a comparable sized prior-art separable zipper.
  • the receiving aperture 65 of the device 10 of FIGURE 1 has a diameter at least as large as the overall length of the slider 24.
  • the area of the receiving aperture 65 of the device 10 is very much greater than the area of one of the slider ports, such as the left slider port 39b.
  • each of the above-described embodiments of the invention greatly reduces the care and dexterity required in connecting the ends of a separable zipper. Rather than having to first feed a relatively small terminal pin through one port of a slider as is done with conventional pin-and-socket type separable zippers, relatively large and substantially self-aligning terminals are first fastened and then, if need be, rotated until the rows of zipper teeth are properly aligned for interfastening by the slider.
  • the present invention can be practiced using a terminal arrangement wherein the nesting portions are disposed to one side of the slider when in its rearmost position so that the axis of rotation of the terminals does not intersect the line along which the slider moves, as is the case with each of the presently illustrated embodiments.
  • other terminal devices are contemplated wherein the slider is carried in its rearmost position on the terminal having the female rather than the male structure of the nesting portions, so that the term "receiving terminal" as used herein is not intended to be limited to terminals having the female structure.
  • Other modifications and alternatives are within the scope of the present invention as defined by the appended claims.
