Definitions

  • the present invention refers to a slider for a slide fastener. More in detail, the invention relates to a slider with a bridge that can be shifted between a first position and a second position, for example to remove or replace a pull tab.
  • a slide fastener basically comprises a pair of tapes bearing respective rows of teeth, top and bottom stops, and a slider with a pull tab.
  • the slider basically comprises an upper blade, a lower blade, a central portion between the upper and lower blade, which is called diamond, and a bridge extending over the upper blade.
  • the pull tab is inserted between the bridge and the upper blade and is held in position by the bridge.
  • a technical problem encountered in the current technique of manufacturing slide fasteners is the need of a removable pull tab.
  • a removable pull tab may be desired for example to avoid damage of the pull tab caused by the manufacturing process of the slide fastener, or of the item (e.g. suit, bag, etc.) comprising the slide fastener. For example, it may be desirable to protect an expensive metal puller from manufacturing steps such as sewing and finishing. Especially in the field of luxury goods, the pull tab may be a delicate and expensive item. It should also be considered that a damage of the pull tab is likely to be visible and disappointing for the customer.
  • the pull tab is indispensable to release a locking device and open the slide fastener. Another reason to provide a removable pull tab is customization of the slide fastener.
  • a known solution is the use of a disposable plastic pull tab during the manufacturing process, which however has some disadvantages including the need of ab additional disposable pull tab and the step of cutting or breaking the plastic pull tab at the end of the process, for insertion of the true pull tab intended for the product.
  • EP 2 322 050 discloses a process for making a slide fastener wherein a protective cap is applied on the front portion of a resilient member of the slider.
  • the protective cap allows easy insertion of a puller and, where appropriate, releases a locking device of the slider, thus allowing the opening and closing of the slider without the puller.
  • This system is satisfactory but still has the drawback of requiring an additional item, that is the protective cap.
  • the purpose of the invention is to avoid the above drawbacks of the prior art.
  • the aims of the invention include the provision of a simple and cost-effective slider with a removable and interchangeable pull tab, as well as a releasable locking system.
  • the slider body includes a diamond, an upper blade, a lower blade and a bridge.
  • Said bridge is connected to the slider body by connection means allowing a combination of linear displacement and pivoting relative to the slider body between two end positions. Said two positions include: i) a first position wherein the bridge is engaged with a retaining member of the slider body, and ii) a second position wherein the bridge is disengaged from said retaining member and is rotated relative to the slider body.
  • the first position can be termed “closed” and the second position can be termed “open”.
  • the bridge in the second position may define a front passage suitable for insertion or removal of a pull tab. Said passage is closed when the slider is in the first position, thus holding the pull tab in place.
  • Said linear displacement is preferably in a longitudinal direction of the slider.
  • Said term of longitudinal direction denotes a direction which is parallel to the sliding direction of the slider. In some embodiments, it is substantially parallel to the upper and lower blades.
  • the bridge is connected to the slider body via a rotation pin inserted in at least one slot.
  • the rotation pin provides the pivoting feature while the slot provides the linear displacement feature.
  • a rotation pin is fixed to the slider body and the bridge comprises one or more slot to engage said pin.
  • a preferred embodiment has a fixed pin and sliding slot(s); alternative embodiments may be realized with a sliding pin.
  • the slider comprises elastic means disposed to urge the bridge in the first position. More preferably, said elastic means are configured to oppose the linear displacement of the bridge relative to the slider body. In a preferred embodiment, said elastic means are housed in the bridge.
  • the elastic means may be for example a coil spring. Preferably the elastic means are energized (for example a spring is slightly compressed) when the bridge is in the first position.
  • the slider comprises also locking member to prevent undesired sliding.
  • the locking member may be configured to protrude through an opening of the upper blade, in such a way that when the slider is fitted on a slide fastener, the locking member is able to engage the teeth in the region between the upper and lower blades, thus locking the slider itself.
  • One of the preferred aspects of the invention is the integration between the bridge and the locking member.
  • the locking member is engaged when the bridge is in the first position, and is released when the bridge is in the second position.
  • said locking member is associated to the bridge, for example it is at least partially inserted in a recess of the bridge. Both the locking member and the bridge are pivotable together around a pin; the locking member however has only the degree of freedom of pivoting around said pin, while the bridge is also longitudinally slidable relative to said pin. More preferably, said elastic means act between the bridge and the locking member.
  • the locking member comprises a cam which copies a profile of the bridge, suitable to provide at least a partial disengagement of the locking member upon displacement of the bridge.
  • a pull-tab can be easily removed or replaced by opening and closing the bridge.
  • a temporary pull-tab can be inserted whenever necessary during the manufacturing process of the slide fastener, or of an item comprising the same. Then the temporary pull tab can be removed and a final pull tab inserted. Opening the bridge portion of the slider is easy but, at the same time, the closure is safe and reliable thanks to the combined pivoting and displacement.
  • the invention eliminates the need of expensive design of the slider body, including moving parts such as slidable pull tab carrier and/or elastic members mounted directly in the slider body.
  • the bridge in the open position can be used as a puller, which means that the slide fastener can be operated (e.g. during the manufacturing of an item) even without a pull tab.
  • Another advantage of the invention is the full integration with a locking system when provided. Since the locking member is associated with the bridge, the locking of the slider is automatically released by opening the bridge, even without a pull tab.
  • the figures show a slider 1 for a slide fastener, which basically includes a slider body 10 with a diamond 11, an upper blade 12, a lower blade 13 and a bridge 14.
  • the bridge 14 is shiftable between a first position of Fig. 1 , and a second position of Fig. 6 .
  • the second position of Fig. 6 is also termed open position, since the rotated bridge 14 defines a front passage 33, which is suitable for insertion or removal of a pull tab 40 (see also Fig. 9 ).
  • the first position of Fig. 1 is also termed closed position, since the front passage 33 is closed and a pull tab can be held in place between the bridge 14 and the upper blade 12.
  • the bridge 14 In the first position, the bridge 14 is engaged with a retaining member 19 of the slider body 10 ( Fig. 2 ).
  • a spring 24 housed in a seat 30 of the bridge 14 serves to normally keep the bridge 14 in the first closed/locked position.
  • the bridge 14 can pass from the first position of Fig. 1 to the second position of Fig. 6 by a linear displacement followed by a rotation around a pin 17.
  • the linear displacement ( Figs. 3 to 5 ) disengages the bridge 14 from the retaining member 19; the rotation around the pin 17 ( Figs. 6, 7 ) opens the front passage 33.
  • the bridge 14 comprises a base 15 and a distal end 16 opposite to said base 15.
  • the rotation pin 17 is fixed to the slider body 10 and is received in a pair of slots 18 of said base 15.
  • the slots 18 are formed on lower projections 31 of the base 15. Said slots are denoted by the slotted line of Fig. 1 ; one of the slots is visible in the cross section of Fig. 5 and the two slots are also visible in the exploded view of Fig. 8 .
  • the connection via pin 17 and slots 18 gives the bridge 14 the ability to linearly slide from the position of Fig. 1 to the position of Fig. 3 , and to rotate to reach the open position of Fig. 6 .
  • the distal end 16 is suitably configured to engage and disengage the retaining member 19 upon a linear shift of the bridge 14.
  • the front of the distal end 16 has a suitable recess 20 for engagement with a projecting tooth 21 of said retaining member 19.
  • the retaining member 19 is integral with the slider body 10 ( Fig. 2 ).
  • the embodiments of the figures also comprise a locking member 22.
  • said locking member is fitted in the bridge 14.
  • Said locking member 22 has a protrusion 23 adapted to engage the teeth of a sliding fastener (not shown) operated by the slider 1, to prevent undesired opening of the slide fastener.
  • the locking member 22 can pivot together with the bridge 14 around the same pin 17. However, the locking member 22 can only rotate around the pin 17, while the bridge portion 14 has also the additional degree of freedom of a certain linear translation, thanks to the slots 18.
  • the pin 17 is inserted through and supported by projections 25 of the upper blade 12 of slider body 10.
  • the locking member 22 is partially received in a seat 26 of the bridge portion 14, in such a way that a hole 27 of said locking member is aligned to holes 18 of said projections 25 and faces the slots 18.
  • the pin 17 is inserted through the holes 28 of said projections 25, the hole 27 of the locking member 22, and the slots 18 of the bridge 14.
  • the hole 27 of the locking member 22 has substantially the same diameter of the pin 17, while the slots 18 are larger than said pin 17 in a direction of sliding of the bridge 14, which is the longitudinal direction in the figures as denoted by d in Fig. 3 .
  • the coil spring 24 abuts against the bottom of the seat 30 and against a surface 29 of the locking member 22.
  • the locking member 22 has only one degree of freedom and can only pivot around the pin 17, while the bridge 14 is also allowed to longitudinally slide by the displacement of the pin 17 in the slots 18.
  • the bridge 14 and the locking member 22 can rotate together around the pin 17, during the opening of the bridge 14, as if they were a rigid body. However, the bridge 14 can also slide in a linear fashion, relative to the locking member 22 and slider body 10, compressing or releasing the spring 24.
  • the locking member 22 comprises also a cam 34, on the opposite part of the locking protrusion 23 relative to the pin hole 27. Said cam 34 engages a respective profile 35 made in the base 15 of the bridge 14.
  • FIG. 10 released
  • Fig. 11 locked
  • the locking member 22 has a step 37 forming a plane surface substantially parallel to the opposite surface of the bridge 14.
  • the coil spring 24 can be received between the locking member 22 and bridge 14 without the need of making a deep hole in the bridge 14.
  • This embodiment may be preferred to ensure even better and smooth operation of the coil spring.
  • the bridge 14, in particular the base 15, is simpler to manufacture.
  • the slider 1 operates in the following manner.
  • the coil spring 24 In the closed/locked position of Figs. 1-2 , the coil spring 24 is slightly compressed. Due to its position and inclination, the spring 24 keeps the bridge 14 in the closed position, by urging the distal end 16 against the retaining member 19 ( Fig. 2 ). At the same time, the spring 24 tends to rotate clockwise the locking member 22 around the pin 17, so that the locking member 22 is also urged in its locked position, against a step 36 of the slider body 10, as shown in Fig. 2 .
  • the protrusion 23 is fully extended in the passage 32, for engagement with the teeth of the fastener.
  • the locking member 22 can be released by a pull tab during the normal use, lifting the middle of the locking member around the pin 17 until the teeth are freed from the protrusion 23.
  • the bridge 14 in this case will remain in its closed position, due to the engagement of front recess 20 and retainer 19, which is unaffected by the action on the pull tab.
  • Fig. 3 shows how to open the bridge 14.
  • the bridge 14 is first pushed as denoted by d, relative to the slider body 10 and locking member 22, against the spring 24 which is further compressed. By doing so, the distal end 16 is progressively disengaged from the retaining member 19 as seen in the sectional view of Fig. 4 .
  • the pin 17 slides from one end to another end of the slots 18, that is from left end to the right end in the figures.
  • the locking member 22 is rotated around the pin 17 by the cam 34 copying the profile 35, thus starting to disengage the lock.
  • the rotation of the bridge 14 opens the front passage 33 which allows insertion or removal of a pull tab.
  • the locking member 22 is released as well, pivoting together with the bridge 14 and bringing the protrusion 23 away from the locking position in the passage 32.
  • Fig. 9 the same bridge 14, when in the open position of Fig. 6 , could be used to manually open or close the slide fastener.
  • the bridge 14 when the bridge 14 is opened and the locking member 22 is also released, the bridge itself can be used as a sort of puller. This feature may be useful during a manufacturing process of the slide fastener or of an item comprising the same, because the slide fastener can be opened or closed even without a pull tab.
  • the closing of the bridge is as follows. Starting from the open position of Fig. 6 , the bridge 14 is lowered until it is substantially horizontal, then it is shifted back to the position of Fig. 1 , slightly compressing the spring 24. When the position of Fig. 1 is reached, the system is stable thanks to the spring 24 urging the end 16 against the retainer 19 and the locking member 22 against the step 36 of the body 10.
  • the figures show also the advantage of a simple construction, especially of the slider body.
  • the slider body 10 has no moving parts and the spring 24 is fully received in the slider bridge 14. No hole or seat for a spring is to be provided in the body 10.
  • Another advantage is that a single elastic element, such as the spring 24, keeps both the bridge 14 and the locking member 22 in the closed/locked position.
  • the invention combines the functionality of an openable bridge, removable pull tab and releasable locking system, in an efficient and cost-effective manner.
