Definitions

  • the present invention refers to a slide fastener and to a top stop of a slide fastener.
  • the invention relates in particular to fluid-tight slide fasteners and top stops of fluid-tight slide fasteners.
  • a slide fastener in essential terms, comprises a pair of tapes bearing respective rows of teeth, top and bottom stops, and a slider for opening and closing the fastener by engaging and disengaging the teeth.
  • the slider is operated by a puller (or pull-tab) which is usually connected to the slider by a ring or a ring shaped end portion of the same puller.
  • top and bottom stops are at opposite ends of the slide fastener, which is completely closed when the slider reaches the top stop.
  • Fluid-tight slide fasteners are used in sports and outdoor activity items, diving or sailing suits, camping tents and the like, and are required to securely prevent the passage of a liquid and/or gas, e.g. water and/or air.
  • a fluid-tight fastener must ensure fluid-tightness even under a significant pressure difference between the interior and the exterior, for example up to about 2 bars.
  • Fluid-tight slide fasteners are realized for example with layered tapes made of a textile core with a waterproof coating layer, and injection-molded teeth.
  • the slider of a slide fastener comprises upper and lower blades, lateral flanges and a central portion, called diamond, connecting the upper and lower blades.
  • the top stop is a substantially U-shaped element with leg portions defining a front opening for the diamond of the slider, and a seat for receiving said diamond when the slide fastener is fully closed. It is known technique to provide a suitable shape of the lateral flanges of the slider so that they act on the sides of said leg portions of the U-shaped top stop, in order to close said front opening in a fluid-tight manner when the slider reaches the full-closed position.
  • the slider in order to guarantee the fluid-tightness of the closed slide fastener, during the use, the slider should be kept in position and prevented from moving away from the top stop. In fact, an accidental displacement of the slider, even of few tenths of a millimeter, may compromise the fluid-tightness of the fastener at the region of the top stop and/or between the teeth.
  • the technical problem underlying the invention is to provide a reliable and safe closure of a slide fastener as defined above, avoiding the slider from leaving the position where the fastener is fully closed, allowing at the same time a quick and easy opening of the fastener itself.
  • a slide fastener comprising a pair of tapes, carrying respective teeth, a top stop and a slider comprising a puller, the slider being movable up to a closing position of the fastener where said slider is in contact with said top stop, characterized in that the top stop comprises at least one retaining element adapted to retain the slider in said closing position.
  • said at least one retaining element is integrally formed with the top stop.
  • said retaining element is disposed to act as a stop means for the slider when the puller is fitted on the top stop in a determined locking position.
  • said locking position is a position where the puller is lying on the top stop, substantially parallel to the sliding direction of the slider.
  • a retaining element is integrally formed with the top stop, having a surface disposed to act as a stop means against a contact face of the puller, when the puller is fitted on the top stop in said locking position.
  • the top stop further comprises at least one locking element, adapted to a snap engagement with a suitable seat or portion of the puller, to retain the puller in said locking position.
  • said seat or portion of the puller is a ring or a ring portion connecting the puller to the slider.
  • said at least one locking element is an elastically deformable element adapted to snap on the ring connecting the puller to the slider.
  • said locking element has an elastically deformable stem portion and a head portion projected from top of the stem portion, defining an undercut recess for receiving the ring of the puller.
  • Said locking element(s), according to the invention are able to engage/disengage the ring of the slider by elastic deformation induced by contact with the ring itself when the puller is locked or unlocked on the top stop.
  • the head portion of the locking elements has a suitably profiled surface to allow deformation of the element by contact with the ring of the slider, while the puller is pressed down to the locking position, or lifted from that position. Thanks to said profiled surface, contact with the ring of the puller results in a force directed to deform the locking element(s) in such a way to receive or, respectively, to free the ring of the puller, as will be clearer hereinbelow with the help of an example.
  • said at least one retaining element of the top stop is formed as a wall of the top stop, comprising a base part with a surface adapted to act as a stop means against a contact face of the puller, and two locking elements formed as elastically deformable toothed elements projecting upwards from said base part and each defining an undercut recess for receiving the ring of the puller.
  • the base part of the wall integrally formed with the top stop has a front surface facing the slider and a rear surface adapted to act as a stop means against a bottom face of the puller, to retain the slider when the puller is in the locking position.
  • the top stop comprises at least one pin adapted to engage a corresponding hole of the puller, to retain the puller from lateral movement.
  • the retaining element is adapted to cooperate with a corresponding locking element of the slider.
  • the top stop has a suitable seat or recess for receiving a locking element projecting from the front of the slider, the locking element of the slider being engaged in said seat or recess of the top stop when the slider reaches the top stop.
  • a disengagement system e.g. by pressing a disengagement button, can also be provided on the top stop, to unlock the slider.
  • An object of the invention is also a top stop for a slide fastener, the slide fastener comprising a pair of tapes, carrying respective teeth, and a slider comprising a puller, the slider being movable to a closing position where said teeth are fully engaged and the slider is in contact with the top stop, the top stop being characterized by comprising at least one retaining element(s) as described above.
  • the invention provides a top stop for a slide fastener wherein said at least one retaining element is formed as a front wall of the top stop, the top stop being adapted to receive the puller of the slider in a locking position, said front wall comprising a surface adapted to act as a stop means against a contact face of the puller when the puller is fitted in said locking position.
  • the invention has the advantage that the slider is securely kept in the closing position. It should be noted that the snap-on engagement between the locking elements and the slider, namely the puller thereof, provides a quick and simple locking/unlocking action, so that the slider of the fastener is securely kept in the closing position and prevented from accidental opening even under intensive use, but the user can open the fastener rapidly and easily at any time.
  • the invention is particularly useful in a fluid-tight fastener, where a small deviation of the slider from the full-closing position may compromise the fluid-tightness.
  • an item fitted with a slide fastener according to the invention such as a sports garment or the like, gives reliable fluid-tight performance with easy and safe use.
  • FIG. 1 is a perspective view of the top end of a slide fastener according to an embodiment of the invention.
  • FIG. 2 is a side view of the fastener of FIG. 1 .
  • FIG. 3 is a side view of the fastener of FIG. 1 , with the puller of the slider in a different position.
  • FIG. 4 is a top view of the fastener, in the position of FIG. 3 .
  • FIGS. 5 and 6 are cross-sectional views according to lines V-V and VI-VI of FIG. 4 .
  • FIG. 7 is an enlargement of FIG. 5 .
  • FIG. 1 shows a top portion of a slide fastener 1 , in accordance with a preferred embodiment of the invention, comprising a pair of tapes 2 , equipped with teeth 3 , a top stop 4 , and a slider 5 with a puller 6 .
  • the puller 6 is connected to the slider 5 by a ring 7 .
  • the slider 5 is movable in a sliding direction, parallel to tapes 2 , up to a closing position where the slide fastener 1 is fully closed, i.e. all teeth 3 are engaged and the slider 5 is in contact with the top stop 4 . Said closing position is shown in FIG. 1 .
  • tapes 2 an teeth 3 can be according to known art and are not discussed in detail.
  • tapes 2 are made of a textile core layer fully coated on both sides by a suitable waterproof layer and teeth 3 are injection-molded on tapes 2 .
  • the top stop 4 in a fluid-tight slide fastener, can also be injection-molded on tapes 2 .
  • the slider 5 ( FIG. 2 ) substantially comprises upper and lower blades 8 , 9 with lateral flanges 10 , 11 on both sides, and a diamond connecting said upper and lower blades 8 , 9 .
  • Flanges 10 and 11 in use, act on suitable contact faces of teeth 3 in order to bring the facing teeth of the tapes 2 to reciprocal engagement, according to known art.
  • the puller 6 can be fitted from the position of normal use, as seen in FIGS. 1 and 2 , to a locking position on the top stop 4 , shown in FIGS. 3 and 4 . In said locking position, the puller 6 is lying on the top stop 4 , substantially parallel to the sliding direction of the slider 5 .
  • a front wall 20 is integrally formed in the top stop 4 , acting as a stop means against a bottom contact face 30 of the puller 6 .
  • the wall 20 has a rear surface 32 ( FIG. 2 ) acting as a stop means against the contact face 30 of the puller 6 , when in position of FIGS. 3-4 .
  • the wall 20 has a front surface 31 facing the slider; advantageously, there is a gap between said front surface 31 and the slider 5 for clearance recovery.
  • the contact face 30 may be slightly curved and, in this case, the rear surface 32 of wall 20 is curved accordingly ( FIG. 4 ).
  • Two toothed elements 22 , 23 project upwards from the central portion of base part 21 of the wall 20 , adapted to mechanically engage the ring 7 in order to “lock” the puller 6 in the position of FIGS. 3-4 .
  • Each of said elements 22 and 23 has an elastically deformable stem portion projecting upwards from the base 21 , and a head portion defining an undercut recess 22 for receiving the ring 7 when the puller is in the locking position.
  • each of elements 22 , 23 has a stem portion 24 projecting upwards from base part 21 of the wall 20 , and carrying a head portion 25 projecting laterally and outward from the top of the stem 24 , defining inclined surfaces 26 and 27 converging to an edge 28 , and the undercut recess 22 below said edge 28 and between the base 21 and the head 25 itself.
  • Pressing the ring 7 against faces 26 or 27 has the effect of bending laterally and inwards the stem portion 24 of the toothed elements 22 and 23 , thus engaging the ring 7 in the recess 22 or vice-versa disengaging the same ring 7 and puller 6 from the locking position.
  • the top stop 4 also comprises a pin 40 which is received in a corresponding hole 41 of the puller 6 , when the puller 6 is in said locking position. Said pin 40 , received in the hole 41 , retains the puller 6 from lateral movement.
  • the pin 40 is elliptical and frusto-conical, with a cross section decreasing from base to top.
  • the pin 40 may also be cylindrical in simpler embodiments.
  • the invention is open to many variants.
  • the toothed elements 22 , 23 or equivalent locking elements can engage a suitable seat (e.g. a recess) of the puller, rather than the ring connecting the puller to the slider.
  • a suitable seat e.g. a recess
  • the position of said locking elements can be different according to the needs and/or the design of the top stop.
  • the puller 6 may also be shaped in a different manner, for example with a hole in the bottom part defining a ring portion connecting the puller with the slider 5 .
  • the retaining element rather than wall 20 , may be realized in different ways, including a plastic or metal element not integrally formed with the top stop itself.
  • the slider 5 may be equipped with a locking element, adapted to cooperate with another engagement element provided in the top stop 4 , so that when the slider 5 reaches the top stop 4 , said slider is locked to the top stop and prevented from sliding away.
  • An unlocking system may be incorporated in the top stop.
  • the slider for example has a first coupling element protruding from the front of the slider itself, adapted to snap on a second coupling element or recess of the top stop when the slider reaches the top stop.
  • Said second coupling element or recess may be provided e.g. on face 31 or equivalent part of the top stop 4 .
  • the top stop has an unlocking button associated to said second coupling element of the top stop, so that acting on said button the user can move the second coupling element to a disengaging position, freeing the slider from the top stop.
  • the user lowers the pull-tab 6 from the position of use of FIGS. 1-2 to the locked position of FIGS. 3-4 .
  • the ring 7 contacts the upper surfaces 26 of teeth 22 , 23 ( FIG. 2 ), and due to inclination of said surfaces 26 , the stems 24 are deformed until the ring 7 can overcome the edge 28 , and reach the undercut recesses 22 .
  • the fastener is unlocked by lifting the puller 6 , so that the ring 7 bends the elements 22 , 23 pressing against the contact surfaces 27 , until the ring 7 itself reaches the edge 28 and is freed to the use position of FIGS. 1-2 again. Then, the user can open the slide fastener 1 as usual.
  • the puller 6 is locked and unlocked manually and in a quick and immediate way by lowering or, respectively, lifting the puller. Notwithstanding this, when the puller 6 is locked the slider 5 is firmly secured on the top stop 4 , and accidental opening of the fastener and/or loss of the fluid-tightness is prevented in a reliable way.
