Definitions

  • H. HEQMBERGER BY A. FROHL'I'C'HP may: ATTORNEY TAPE-SUPPORTED SEPARABLE SLIDE FASTENER
  • bottom stop a separable end stop
  • our invention involves the use of a pin socket which is longitudinally slidable on the coupling element and the adjoining guide pin at the end of one half of the fastener.
  • Internal camming formations engageable with respective extensions of the two coupling elements or fastener chains, ad vantageously the guide pin on one chain and a similar spur on the other chain, translate any spreading of the tapes below the bottom stop into an upward shift of the socket, i.e. a movement thereof toward the slider, with resulting positive interlocking of the terminal links of these chains.
  • the camming formations are constituted, according to a more specific feature of our invention, by lateral walls of a downwardly flaring channel in the pin socket; a divider or spreader at the mouth of that channel, remote from the slider, forms a branch channel with one of the sidewalls to engage the spurlike extension of the nondetachable coupling element with freedom of limited relative slidability.
  • This divider may be part of a web interconnecting a pair of parallel flange portions or shields similar to those of a conventional slider.
  • the length of the two guide members integrally extending from the fastener chains, i.e. the pin and the spur, is advantageously so chosen that these members project from the downwardly diverging branches of the socket channel when the socket is in a raised position.
  • the retaining spur may comprise an upwardly facing lug which a downwardly facing lug on the guide pin engages when the pin is fully inserted. The coupling elements are then in the proper meshing position in which the lowest link of one coupling element is opposite the lowest gap on the other coupling element.
  • a flaring mouth on the slider bounded by lips with rounded edges lining up with the sidewalls of the pin-socket passage upon juxtaposition of these two sliding bodies, permits opening of the fastener and complete separation of its halves, including withdrawal of the pin from the socket, by a transverse pull exerted on the fastener above the slider which therefore should be free to slide off the top of at least one of these halves.
  • FIG. 1 is a perspective view of a slide fastener embodying the invention
  • FIG. 2 is a plan view, drawnto an enlarged scale, of the bottom portion of the fastener of FIG. 1;
  • FIGS. 3 and 4 are fragmentary plan views similar to FIG. 2 but showing the fastener in different operational positions;
  • FIG. 5 is a cross-sectional view of the fastener taken on the line V V ofFIG. 3;
  • FIG. 6 is a view of a garment fitted with a slide fastener embodying the invention.
  • FIG. 7 is a plan view of a modified form of slide fastener embodying the invention.
  • FIG. 7A shows a detail in section taken on the line A A of FIG. 7;
  • FIGS. 8 to 12 are enlarged plan views of the bottom portion of the slide fastener of FIG. 7 in different operating positions.
  • FIG. 13 illustrates a step in the manufacture of slide fasteners of the type shown in FIG. 7.
  • stringer tapes la and 1b adapted to be sewn to a garment 7 support fastener chains 2a and 2b (FIG. 1) which are coupled and uncoupled by movement of a slider 3 away from and toward an end stop 4.
  • the ends of the stringer tapes are reinforced and made resilient slotted or perforated stifi'eners 21a, 21b (FIGS. I, 2, 4) or 121a, l2lb (FIGS. 3 and 5) of synthetic resinous sheet material bonded to the tape; similar strips 21c, 21d (FIG. 1) are integral with the upper ends 28a, 28b of chains 1a, 1b as part of the top stop of the fastener.
  • Bottom stop 4 comprises a pin socket 5, carried by fastener half lb, 2b, into which a pin 6 on the other fastener half la, 20 is insertable.
  • bottom stop 4 Details of the bottom stop 4 are illustrated on an enlarged scale in FIG. 4 showing the pin 6 adjoining the lower end of the coupling element 2a as a downward integral extension thereof.
  • the pin 6 is preferably made of flexible material and is also unitary with, or bonded to, the reinforcing strip 21a or 121a overlying the tape la.
  • a similarly shaped retaining spur 13 extends integrally from the coupling element 21: and is unitary with or bonded to the other reinforcing strip 21b or l2lb.
  • the pin socket 5 has an internal channel 12, substantially of inverted-Y shape, with a rising stem portion and with downwardly diverging branch portions respectively receiving the pin 6 and the spur 13.
  • the branches are divided by a spreader 11, which serves as a web interconnecting a pair of parallel shield plates 9, l0, and are externally bounded by sidewalls formed by a pair of flanges 15, 16 which depend from shield plate 9 but terminate short of shield plate 10 to leave a pair of lateral slots for the entry of the tapes Ia. Ib and their overlying reinforcing strips as best seen in FIG. 5.
  • Socket 5 like the generally similar slider 3, is preferably molded integrally from thermoplastic material which may or may not be the same as that from which the monofilamentary fastener chains are shaped, e.g. by a conventional extrusion process and subsequent deformation to form the coupling heads.
  • the pin socket 5 is limitedly slidable along spur l3 (and therefore with reference to fastener half 1b, 2b) and is shown in FIG. 2 near its topmost position.
  • Camming formations constituted by the convex inner surfaces of flanges 15 and 16 cause this socket to move automatically into that position in response to a transverse pull exerted on the fastener below the socket, as represented by arrows 8a, 8b.
  • the upper limit of the socket movement lies at the point where the spreader 1 l abuts the lower end of the fastener 2 consisting of the intermeshing coupling elements 2a, 2b; see FIG. 2. In this position the stem of channel 12 receives the lower ends of the coupling elements and positively prevents their separation.
  • the pin socket occupies a lower position, shown in FIG. 4, in which a stop 25 on the spur 13 engages a shoulder 26 (FIG. 2) on the wall 16 of pin socket 5. These abutting surfaces prevent complete removal of the socket from the spur 13.
  • Slider 3 with its spreader 111 and generally Y-shaped channel 112, constitutes a substantial mirror image of socket 5, the channels 12, 112 of the two juxtaposed bodies 3, forming a roughly X-shaped passage with slightly curved branches accommodating the similarly curved extremities 6, 13 of coupling elements 2a, 2b.
  • Pin 6, therefore, is positively guided downwardly upon insertion from above and is also gently cammed outwardly upon exertion of a lateral pull above the slider as indicated by arrows 108a, l08b in FIG. 4.
  • FIGS. 7 13 we have shown a similar fastener assembly wherein elements corresponding to those of the preceding embodiment have been designated by like numerals with the addition of a prime mark; this obviates any need for their detailed description, except insofar as the elongated extensions 6' (guide pin) and 13' (retaining spur) of the fastener chains 2a, 2b are concerned.
  • Pin 6 and spur 13 are angularly bent, rather than curved like the guide members 6, 13 of the preceding embodiment, in substantial conformity with the legs of the generally X-shaped passage defined by the channels 12 and 112 in the juxtaposed position of slider 3' and socket 5. At their point of closest approach, i.e. at the waist ofthe X" when the parts in their position of incipient engagement or disengagement illustrated in FIG.
  • pin 6' and spur 13 are provided with a pair of coating formations which limit the insertion of the pin and cause the downward entrainment of the spur by the pin, relative to the juxtaposed bodies 3' and 5, during the insertion step; these formations have been shown as a downwardly facing lug or tooth 17 on pin 6' and an upwardly facing lug or tooth 18 on spur 13', Upon a raising ofthe socket 5' (FIG. 12) so that its web 11 separates the lower ends of these guide members within channel 12 while maintaining the interconnection ofthe fastener chains as described above, the lugs l7, 18 move apart but still maintain their confronting position.
  • FIGS. 8 12 clearly show the unsymmetrical shape of web 11' with its straight flank 11a and sloping flank 11b, similar to those of web 11 in the preceding embodiment, which converge toward an abutment surface confronting the transverse edge oflug 17 so as to prevent the socket 5' from rising above its limiting position illustrated in FIG. 12.
  • the length of guide members 6 and 13 is such that they pass substantially completely through the X-shaped passage 12, 112' when the slider 3' is depressed to push the socket 5 into its bottom position.
  • the corresponding members 3 and 13 are somewhat longer and advantageously more flexible.
  • Fastener chain 2a whose coupling heads are upwardly staggered with reference to those of chain 212, is separated by a notch 22 from the guide member integral therewith, i.e. from the pin 6' in FIGS. 8, 9, ll, 12 and from the spur 13 in FIG. which illustrates the reverse arrangement with that pin extending from chain 2b.
  • Notch 22 is, of course, designed to receive the lowermost link of chain 212' which is separated from its guide element by a small incision 23 only.
  • the slider for the lower fastener 2" may be slipped over the guide members 28a, 28b of the top stop of that fastener.
  • a slide fastener comprising a pair of stringer tapes; a first and a second coupling element respectively secured to said tapes, said elements being provided with interengageable links; a slider movably mounted on said elements for interlocking their links upon displacement therealong in an upward direction and for separating their links upon displacement therealong in a downward direction; and a bottom stop separably interconnecting said elements at their lower ends, said bottom stop including a socket secured to one of said tapes with limited relative mobility by the lower extremity of said first element, said socket having an internal channel removably receiving the lower extremity of said second element, said socket being provided with camming formations engageable by said lower extremities upon a spreading thereof for exerting an upward force on said socket, said camming formations being a pair of sidewalls bounding said channel, the latter diverging downwardly and being provided at the bottom with a spreader defining with said sidewalls a pair of channel branches respectively receiving said extremities, one of said extremities partly overlying said spreader for preventing
