Definitions

  • the present invention relates to an improved locking stop mechanism, more specifically an improved locking stop mechanism for a slide fastener.
  • the present locking stop invention is particularly useful but not limited to use with slide fasteners in which the fastener ideally remains in the closed or locked position.
  • slide fasteners are well known and the list of applications to which slide fasteners may be applied continues to increase. Likewise, the demand for high quality fasteners to meet the requirements for particular industries also continues to increase.
  • Conventional slide fasteners comprise a pair of stringers, wherein, each stringer is comprised of a tape and coupling elements, and a slider that moves along the coupling elements of the stringers and in so doing engages or disengages the coupling elements depending on the direction of movement of the slider.
  • An end stop is usually placed at the one end of one or both stringers to prevent the slider from moving beyond the coupling elements on one or both stringers, which would otherwise allow 'unpeeling' or disengagement of the coupling elements and separation of the stringers.
  • manufacturing industries for example the motor vehicle trade, and soft furnishing market it is often required to secure large pieces of heavy duty material together.
  • split arrester or top stop for a slide fastener for preventing a pair of interengaged fastener stringers from accidentally opening when a slider on the fastener is removed.
  • the split arrester comprises interlocking male and female members mounted on a pair of fastener stringers.
  • the split arrester is limited in strength by the form of the locking mechanism such that sufficient externally applied force may still cause the fastener elements to become detached once the slider is removed.
  • a key feature of the locking stop of the present invention is the shape of the interconnecting members forming the locking stop mechanism for the slide fastener.
  • the fastener locking stop mechanism comprises first and second members that include male and female interlocking portions that are securely mounted on opposing stringers of the fastener. The strength of the engagement of the first and second members of the locking stop is superior such that the fastener is able to withstand external forces which might otherwise encourage a fastener to open once the slider is removed.
  • a locking stop suitable for use with a slide fastener comprising:
  • the first member comprises at least two receiving portions and the second member comprises at least one receiving portion. It is also preferred that the split protruding member is located on the second member.
  • first and second members of the locking stop according to the present invention are comprised of but not limited to plastics material for example polyethylene or polypropylene or derivatives thereof, or polyamides, or derivatives thereof, for example nylon.
  • first and second members of the locking stop according to the present invention are comprised of nylon.
  • the first and second members are also preferably moulded onto the tapes of the slide fastener.
  • first and second members of the locking stop may be treated with a fire retardant.
  • the locking stop members may further comprise other additives for example but not limited to perfumes, lubricants, antimicrobial agents as well as flame retardents.
  • the coil members of the slide fastener are preferably comprised of nylon monofilaments, for example nylon 6, and the tapes of the slide fastener and preferably comprised of polyester.
  • first and second members comprise indentations. These indentations are preferably located on opposing sides of the first and second members respectively.
  • the locking stop is a locking top stop.
  • the locking stop according to the first aspect of the present is comprised of coiled elements, and that each of the first and second members further comprise at least one element.
  • the preferably at least one coiled element are secured to the first and second members by moulding.
  • a slide fastener comprising a locking stop as described in relation to the first aspect of the present invention.
  • a locking stop or a slide fastener as described in relation to the first or second aspects of the present invention respectively, as a closure mechanism in, for example but not limited to clothing, luggage, sports equipment, home and commercial furnishings, transportation vehicles and floor coverings.
  • the first and second members 14, 16 are seen to comprise an undulating profile where the two members interconnect.
  • the first member comprises two concave or receiving portions, 18, 20 otherwise known as female connecting portions and a protruding or male connecting part 24 located between the first and second receiving portions 18, 20.
  • the first member comprises a first (lower) shoulder 30 and a second (upper) shoulder 32 which are shaped to engage upper and lower surfaces 50 and 52 respectively of the second member.
  • the second member 16 also comprises two receiving portions, 25 and 31.
  • the first receiving portion 25 on the second member is complimentary in shape and therefore able to cooperatively engage with protruding portion 24 on the first member.
  • receiving portion 31 on the second member is cooperatively shaped to engage with shoulder portion 32 on the first member.
  • the second member 16 further comprises a first protruding or male portion 19 that is shaped to engage with receiving or concave portion 18 on the first member.
  • the second member 16 also further comprises a second protruding or male portion 21 that is shaped to co-operatively engage with receiving portion 20 on the first member.
  • a key feature of portion 21 is that the portion comprises a split 15 thereby resulting in segments 21 a and 21b.
  • the split 15 ensures that portion 21 and hence segments 21 a and 21 b have sufficient flexibility to enable the segments 21 a and 21 b of portion 21 to be compressed together and thereby connect with receiving portion 20 on the first member 14.
  • the intricate shape of the first and second members ensures a strong locking connection when the first and second members are engaged. However, once the first and second members are caused to engage, the intricate and undulating form of the mating portions of the first and second members combined with the resilient deformation of the segments 21a and 21 b ensures that the first and second members are not readily parted.
  • FIG. 1 the mating relationship and multiple connection points of the first and second members 14, 16 is illustrated as the two members are shown locked together.
  • the first and second members are shown co-joined and attached atop the opposing elements 60, 62 of a slide fastener (slider not shown).
  • the pair opposing elements are mounted on tapes (not shown).
  • Figure 4 there is illustrated an expanded plan view of a section of a slide fastener with a locking top according to the present invention in a closed and locked position as in Figure 1 , in which the tapes 80, 82 carrying the coiled fastener elements 70 are visible.
  • first and second members 14, 16 further each comprise at one end at least one element 71 and 72.
  • the presence of the elements 71 and 72 further increases the strength of the attachment of the first and second members to the tapes 80 and 82 and hence stringers forming the slide fastener.
  • the presence of the elements 71, 72 on the first and second members enables a smooth transference of the slider from the coiled elements to the locking top stop mechanism.
  • FIGS 5 and 6 there are illustrated plan views of a slide fastener with a locking stop according to the present invention in a partly closed position and in a completely closed position respectively.
  • Figures 5 and 6 illustrate slide fasteners with a locking stop in a horizontal orientation, it will be appreciated by one skilled in the art that the slide fastener itself may be used in any orientation.
  • a slider 100 moves along tapes 80 and 82 of the slide fastener, comprising toothed fastener elements 84, 86. As the slider 100 approaches the locking stop members 14, 16, it can be seen that the members 14, 16 are of a suitable size to pass inside and through the slider 100.
  • the members are resiliently compressed or deformed to allow the members to engage and form a locked relationship.
  • the passage of the members 14, 16 through the slider is encouraged and assisted by the presence of grooves or indentations 66, 68 on the outer edges of the members 14, 16.
  • the grooves or indentations, 66, 68 in combination with the resilient flexibility of the members, ensures that the members are brought into a locked relationship.
  • the locking stop mechanism of the present invention therefore ensures a stronger and more secure lock than the usual interdigitation that exists between the fastening elements in a slide fastener.
  • Suitable materials for the locking stop members of the present invention are selected from the group comprising for example but not limited to polymeric materials and derivatives thereof.
  • first and second members of the locking stop of the present invention are preferably comprised of for example polyethylene, polypropylene, polyamides, for example nylon and derivatives thereof. Most preferably, the members are comprised of nylon. In addition, the nylon may further comprise a flame retardant material.
  • the nylon first and second members are moulded to the tapes of the slide fastener.
  • additional attachment means may be employed.
  • the resilient deformability and hence flexibility of the plastic or nylon material enables the first and second members 14, 16 to be compressed as the first and second members pass through the slider. However, once the first and second have passed through the sliders and are in a locked interrelationship, the members again return to their original shape and formation ensuring maximum interaction between the locking portions of the first and second members and hence closure of the slide fastener.
  • the locking stop of the present invention will be utilised in situations where the slide fastener is fitted and then closed and is not then reopened, there remains the possibility that if a slider is again attached to the coupling elements or alternatively a slider tool applied to the coupling elements, as the slide fastener is still fully functioning the fastener could again be operated.
  • a slide fastener may be prepared which comprises two sliders such that for example, one end of the slide fastener is fitted with a further second slider, operating in a reverse direction to the first slider and further comprising a locking stop mechanism at each end of the slide fastener.
