Description

Slider of zipper fastener

Technical Field

The present invention relates to a slide fastener attached to an opening formed in an article such as a garment or a bag, and more particularly to a slider of a slide fastener in which a decorative button-type pull tab is attached to a slider body after the slide fastener is shipped or shipped for aesthetic reasons.

Background

Heretofore, there has been a decorative slide fastener slider equipped with a pull tab having a decorative grip portion. By way of example, french patent No.2248801 shows a decorative slider 100 of this type, reproduced here in fig. 10 for the sake of convenience. The ornamental slider 100 includes a slider body 102 and a pull tab 104 attached to the slider body 102. The pull tab 104 includes a pull tab base 106 and a decorative plate 108 attached to the upper surface of the pull tab base 106. The pull tab base 106 has a pair of opposed legs 110 formed on its lower surface. The opposite leg portions 110 have two engaging portions 112 provided at respective lower ends thereof so as to protrude inward. The slider body 102 has a pull tab attachment tab 114 disposed on its upper surface. The pull tab base 106 is pressed against the pull tab attachment lug 114 with its opposite leg portions 110 sandwiching the pull tab attachment lug 114, so that the engaging portion 112 of the pull tab base 106 is brought into resilient engagement with the attachment lug 114.

Self-locking zipper sliders equipped with a pull tab having a decorative grip portion are well known in the industry. "auto-lock slide" means a slide having an auto-lock mechanism. German utility model registration No.20119609 shows an example of an automatic locking type slide fastener slider 200 having a decorative pull tab, which is also reproduced in fig. 11 herein. The automatic locking type slider 200 is assembled as follows: a leaf spring 202 and a locking member 204 are inserted into the cap 206. Next, a rectangular retaining link 208 is clamped between the thus-coupled cap 206 and locking element 204, with the upper cross-members 209 of the rectangular retaining link 208 being located on the upper surface of the cap 206. Next, the cap 206 is mounted to the upper surface of the slider body 210. Then, the grip portion 220 covers the cap 206, and the holding groove 222 formed in the inner surface of the housing portion 224 of the grip portion 220 is fitted into the upper cross beam 209 of the rectangular holding link 208, so that the grip portion 220 is combined with the slider body 210.

In the ornamental slider 100 of fig. 10, only one resilient snap-in mechanism attaches the pull tab base 106 to the slider body 102. Therefore, if a force is applied to pull the tab base 106 upward, the tab base 106 is easily released from the attachment lugs 114 of the slider body 102. This greatly hinders the convenience of the user in freely operating the pull tab base 106.

In the ornamental slider 200 with the automatic locking mechanism of fig. 11, the grip portion 220 and the rectangular retaining link 208 must be formed as separate components, as this is determined by the configuration of the slider. This makes the assembly work of the slider 200 lengthy and long

Monotonous and expensive to manufacture. Once the assembly of the auto-lock type slider 200 is completed, it is impossible to replace the grip portion 220 even if the user wants to replace it.

In view of the above-mentioned problems, it is an object of the present invention to provide an automatic locking type slider or a slider without a locking mechanism (hereinafter referred to as "free slider") in which a pull tab can be attached to a slider body even if a slide fastener has been shipped or shipped, a pull tab body in the form of a decorative button can be easily attached to the slider body, and also, if a wearer wants to replace the pull tab body, the pull tab body can be freely replaced.

It is another object of the present invention to provide a slider for a slide fastener in which a pull tab can be mounted on a slider body in a well-guided stable manner; particularly if, in the case of an automatic locking slider, the pull tab body can be firmly held on the slider body by a locking member, so that the pull tab can be held on the slider body in a stable manner.

The present invention can be applied to an automatic locking slider and a free slider of a type in which a pull tab can be attached to a slider body after a slide fastener has been shipped or shipped.

As shown in fig. 1, the slide fastener slider according to the first embodiment of the present invention is an automatic locking slider of a type in which a pull tab can be attached to a slider body after shipment or shipment of a slide fastener. The slider comprises a slider body 1 and a pull tab 2 attached to the slider body 1. The slider body 1 includes an upper wing 15 and a lower wing 16 connected at their front ends by a guide post 17 so as to define a zipper tooth guide channel 55 therebetween through which a zipper tooth (not shown) passes as the slider traverses along the row of zipper teeth. A pair of opposed attachment lugs 21 are mounted on the upper wing 15 above the guide posts 17. A claw-shaped hole 22 is formed through the upper wing 15 so as to extend from an end near the attachment lug 21 toward the rear end 28 of the slider body 1. The claw-shaped holes 22 are adapted to freely receive the locking members 19. A slide channel 23 is formed in the upper wing 15 such that it extends from the claw-shaped hole 22 to the rear end 28 and is adapted to slidably receive the closure member 20. The slide channel 23 is substantially as wide as the pull tab attachment pull tab seat 18 in width. The opposite side walls partially defining the slide passage 23 have their respective opposite guide grooves 24 formed throughout the entire length thereof. The ridgelines 31 of the closure member 20 are formed on opposite sides thereof as will be described in detail below. The opposing ridges 31 of the closure member 20 are adapted to slidably engage the opposing guide grooves 24 of the slide channel 23. Spring slots 25 (here the left one can be seen in fig. 1) are formed along the edge of one of the guide slots 24. The coil spring 32 is inserted into the spring groove 25 and has one end abutting against the closing member 20 so as to urge the closing member 20 rearward or in a direction of closing the gap 47 (to be described later) in a normal state.

The opposing attachment tabs 21 have a pair of aligned, penetratingly-formed pin holes 26 through which pins 53 may be passed. The pin 53 is inserted into a pin hole 37 formed through the locking member 19 and a pin hole 45 formed through the pull tab attaching pull tab seat 18. A pair of attachment grooves 27 are formed in the upper wing 15 along the edges of the outer sides of the opposing attachment tabs 21. The proximal end 43 of the pull tab attachment pull tab seat 18 fits securely into the attachment slot 27 of the upper wing 15 so that the pull tab attachment pull tab seat 18 can be secured to the slider body 1. A small projection 30 is provided beside the rear end 28 of the slide channel 23. After the closure member 20 is inserted into the slide channel 23, the tabs 30 are flipped or staked against the slide channel 23 to retain the closure member 20 in the slide channel 23 against displacement.

The locking member 19 is a generally V-shaped plate and is bifurcated to form a pair of upper and lower legs 19a, 19b joined by a vertical portion 19 c. The lower leg 19b is bent downward to provide a locking claw 38. The pin hole 37 is formed through the vertical portion 19c of the locking member 19. The V-shaped locking member 19 has a recess 39 defined between the upper and lower legs 19a, 19b for receiving the pulling shaft 6 of the pull tab 2. The locking member 19 also has an abutting portion 40 disposed below the vertical portion 19 c. A spring 41 is provided between the adjoining portion 40 of the locking element 19 and the slider body 1 and normally urges the adjoining portion 40 upwardly and thus the locking pawl 38 downwardly so that the locking pawl 38 projects into the element guide channel 55, thereby locking the slider to the element row.

The closure member 20 is a generally U-shaped object when viewed from above in fig. 1 and comprises a pair of side arms 20a and a raised closure crossbar 34 connecting the rear ends of the side arms so as to provide an opening 33 between the side arms. The function of the opening 33 is to prevent the closing member 20 from interfering with the operation of the locking member 19. A pair of opposing projections 35 are provided at the front or distal ends of the side arms 20a of the closing member 20 and adapted to cooperate with the projections 50 of the pull tab attaching pull tab holder 18 to prevent the pulling shaft 6 of the pull tab 2 from passing to the other side thereof and disengaging from the slider body 1. In addition, the side arms 20a of the closing member 20 are recessed in the middle of their upper part to provide a notch 36 to temporarily receive the pulling shaft 6. A pair of guide ridges 31 are provided on the outer side of the side arms 20a of the closing member 20 and are adapted to fit into the guide grooves 24 formed in the side walls of the slide passage 23.

The pull tab attachment pull tab seat 18 resembles a housing having a cavity formed therein; the cross section of the utility model is approximately C-shaped; and has a downwardly curved proximal portion. The proximal portion 43 of the pull tab holder 18 is placed onto the attachment tab 21 of the slider body 1 with its lower edge fitted into the attachment slot 27 of the slider body 1, with the pull tab holder 18 mounted on the slider body 1 in a cantilevered fashion. The pull tab seat 18 extends along the length of the slider body 1 and the distal end 49 of the pull tab seat 18 curves downward and terminates short of the rear end 28 of the slider body 1, thus defining a gap 47 with the rear end 28 of the slider body 1. The pull tab seat 18 has a pair of opposed arcuate pull tab holes 46 formed in its underside and adapted to receive the pull shaft 6 of the pull tab 2. A pair of parallel recesses 48 are also formed in the pull tab seat 18 between the pull tab hole 46 and the distal end 49 to temporarily receive the pulling shaft 6 of the pull tab 2. Further, the pull tab seat 18 has a pair of protrusions 50 formed between the pull tab hole 46 and the corresponding parallel recesses 48 so as to cooperate with the protrusions 35 of the closing member 20 to prevent the pulling shaft 6 of the pull tab 2 from being disengaged. The pull tab attachment pull tab seat 18 may be any other suitable shape instead of a C-shape.

As shown in fig. 5, the pull tab 2 comprises a tab body 4 like a disk and a pair of rectangular projecting walls 5 mounted on the lower side thereof and arranged in parallel spaced relation to each other. A traction shaft 6 is installed between the projecting walls 5, connecting them at their middle. When the pull tab 2 is attached to the slider body 1, the pulling shaft 6 of the pull tab 2 is adapted to pass through the gap 47 formed between the pull tab seat 18 and the rear end 28 of the slider body 1 and to be inserted into the recess 39 of the locking member 19. The recess 8 is formed between the parallel projecting walls 5 in the lower side of the pull tab 2 and is adapted to loosely receive the upper portion of the pull tab seat 18. Since the depth of the recess 8 formed in the pull tab body 2 can be compensated by reducing the height of the projecting wall 5, the pull tab body 2 as a whole can be made compact. A pair of open spaces 7 are provided one at each of the front and rear ends of the projecting wall 5, so that the attachment of the pull tab body 4 to the pull tab seat 18 is facilitated. After the pull tab 2 is mounted on the slider body 1, the corners 9 of both ends of the projecting wall 5 serve as fulcrums on which the pull tab 2 pivots in the longitudinal direction of the slider body 1. Further, the outer edges of the opposed projecting walls 5 also serve as fulcrums on which the pull tab 2 pivots in the lateral direction of the slider body 1. The pull tab body 4, the projecting wall 5 and the pulling shaft 6 are integrally formed by die casting from a metal such as zinc alloy, aluminum alloy or the like. Therefore, the pull tab 2 can be made thick and the pull tab 2 can be easily attached to the slider body 1. Each projecting wall 5 of the pull tab 2 is substantially as long in length as the side of the pull tab attaching the pull tab seat 18.

The shape of the pull tab body 4 and the shape and figure of the ornamental portion of the pull tab 2 can be arbitrarily selected. For example, as shown in fig. 9, a dovetail groove or a truncated conical through hole 54 with a large diameter opening at the lower side of the pull tab body 4 may be formed through the pull tab body 4. The ornamental portion 11 is molded over the upper surface of the pull tab body 4 with soft plastic or hard plastic, thus providing the ornamental pull tab 2. The pull tab 2 shown in fig. 6 is a modification of the pull tab 2 shown in fig. 5. In this modified pull tab 2, not two continuous projecting walls 5, but two parallel rows (here, 3 in each row) of interrupted walls 5 are mounted on the underside of the pull tab body 4. A traction shaft 6 is mounted between the opposite central walls 5b to connect them. The terminal walls 5a, 5c on each row are provided to prevent the pull tab 2 from pivoting excessively on the slider body 1.

To assemble the slider body 1, as shown in FIG. 1, first, the coil spring 32 is inserted into the spring groove 25, the closing member 20 is inserted into the slide passage 23 of the slider body 1 and the coil spring 32 is disposed between the closing member 20 and the slider body 1, and the closing member 20 is forcibly pushed forward. After the closing member 20 has advanced beyond the small projections 30 provided on opposite sides of the entrance of the sliding channel 23, the small projections 30 are turned over or staked against the sliding channel 23, thus retaining the closing member 20 in the sliding channel 23 of the slider body 1 from disengaging therefrom. Next, the locking member 19 is inserted between the attachment lugs 21. Then, the coil spring 41 is disposed between the adjoining portion 40 of the locking member 19 and the slider body 1. Next, the pull tab seat 18 is placed over the locking member 19 with the proximal end portion 43 of the pull tab seat 18 fitted into the attachment groove 27 with the locking member 19 seated within the pull tab seat 18. Next, the pin hole 26 of the attachment lug 21, the pin hole 37 of the locking member 19 and the pin hole 45 of the pull tab holder 18 are aligned with each other, and thereafter the pin 53 is inserted into the pin hole 26 of the attachment lug 21, the pin hole 37 of the locking member 19 and the pin hole 45 of the pull tab holder 18. Subsequently, the pin 53 is riveted to the pull tab seat 18 to complete the assembly of the slider body 1.

To attach the pull tab 2 to the slider body 1 thus assembled, as shown in fig. 2, the pair of projecting walls 5 of the pull tab body 4 is slid forward from the gap 47 on the upper wing 15 of the slider body 1, and the notch 8 of the pull tab body 4 is aligned with the attachment pull tab seat 18 of the slider body 1. As a result, the pulling shaft 6 of the pull tab body 4 comes into contact with the closing cross bar 34 of the closing member 20. By simple pushing of the closing member 20 by the pulling shaft 6 of the pull tab 2, the closing member 20 moves forward against the elastic force of the coil spring 32. The closing member 20 is moved forward until the pulling shaft 6 is temporarily received within the notch 36 of the closing member 20. The pulling shaft 6 is pushed further forward, stopping the closing element 20 and allowing the pulling shaft 6 to climb up the opposite protrusions 35 of the closing element 20. Once the pulling shaft 6 received in the notch 36 of the closing member 20 climbs over the opposite projection 35, the pulling shaft 6 pushes the upper leg portion 19a of the locking member 19 upward and enters the notch 39 of the locking member 19, so that the pulling shaft 6 of the pull tab 2 is received in the pull tab hole 46 of the pull tab seat 18; in other words, the pull tab hole 46 of the pull tab seat 18 indirectly receives the pulling shaft 6 of the pull tab 2 through the locking member 19. The closing member 20 is restored to the original position by the elastic force of the coil spring 32. The spring 41 pushes the recess 39 of the locking member 19 downwards, which pushes the pulling shaft 6 received in the recess 39 against the upper wing 15 of the slider body 1, causing the protruding wall 5 to be pressed against the upper wing 15. Since the projecting wall 5 of the pull tab body 4 is pressed against the upward wing 15, the pull tab body 4 does not excessively rock on the slider body 1.

The method of operation of the pull tab 2 thus attached to the slider body 1 is shown in fig. 7 and 8. The pull tab body 4 is pulled upward by holding the front or rear end of the pull tab body 4 and thus the locking unit 19 provided in the pull tab seat 18 is raised, the locking claw 38 of the locking unit 19 is released from the locking engagement with the fastener element, so that the slider can move back and forth along the fastener element. If the user wants to replace the pull tab 2, the closing member 20 is pushed forward by a pointed means. Then, the rear end of the pull tab body 4 is raised and the pulling shaft 6 of the pull tab body 4 moves into the notch 36 of the closing member 20. Then, the closing member 20 is returned to the original position. Next, the pulling shaft 6 of the pull tab body 4 is moved into the parallel recess 48 of the pull tab seat 18. Then, the closing member 20 is moved forward beyond the pulling shaft 6 received in the parallel recess 48, and the rear end of the pull tab body 4 is raised, so that the pulling shaft 6 can be released from the slider body 1 through the gap 47, and the pull tab can be replaced.

The slider of the slide fastener according to the second embodiment of the present invention shown in fig. 3 is a so-called free slider, and this slider is of a type in which a pull tab can be attached to a slider body after shipment of the slider from a factory. The slider body 1 includes an upper wing 15 and a lower wing 16 joined at their front ends by a guide post 17. The pull tab attachment pull tab seat 18 is generally C-shaped in cross section with its proximal end mounted in cantilever fashion on the upper surface of the upper wing 15 above the guide post 17. The distal end of the pull tab holder 18 is bent downward toward the upper wing 15 to terminate short of the upper wing 15, thus defining a gap 47 with the upper wing 15 through which the pulling shaft 6 of the pull tab body 4 can pass. The upper wing 15 has a slide passage 23 formed on its upper surface so as to extend from below the pull tab attaching pull tab seat 18 to the rear end of the upper wing 15. The closure members 20 are adapted to be mounted in opposition along the slide channel 23 to close the gap 47. The opposite inner side walls partially defining the slide channel 23 have their respective opposite guide grooves 24 formed through the length thereof for guiding the closure member 20. A spring groove 25 is formed at the center thereof along the slide passage 23 for receiving a coil spring 32 therein. An insertion cavity 29 is formed in the upper wing 15 as an extension of the slide channel 23 and communicates with the slide channel 23 and the spring groove 25 to receive the two side arms 52 of the closure member 20. The rear end of the insertion cavity 29 constitutes a stop 42 to prevent the closure member 20 from advancing. A pair of small projections 30 are provided on opposite sides of the slide passage 23 adjacent to the rear end of the slider body 1. After the closure member 20 is relatively installed in the slide channel 23, the tabs 30 are staked against the slide channel 23, thus preventing the closure member 20 from disengaging from the slide channel 23.

The closure member 20 is a U-shaped flat base plate 51 and is bifurcated at its forward end to provide a pair of opposed side arms 52. The spring 32 is longitudinally disposed in an opening 33 defined between side arms 52 of the closure member 20. Then, the spring 32 is inserted through the spring groove 25 of the slide passage 23 into the insertion cavity 29 formed transversely to the upper wing 15, thus normally pushing the closing member 20 rearward. A projection 35 is mounted on the upper surface of the base plate 51 of the closing member 20 for closing the gap 47 between the distal end 49 of the pull tab holder 18 and the upper wing 15.

The pull tab 2 having the same shape as that of the first embodiment can also be used in the second embodiment. The projecting wall 5 should be formed shorter if possible, so that the corner 9 of the projecting wall 5 can contact the upper surface of the upper wing 15 when the pull tab 2 swings. In another way, the pull tab receiving hole 46 adapted to receive the pull tab seat 18 of the pull tab 2 should be made compact so that the corner 9 of the projecting wall 5 can not contact the zipper tooth row.

To assemble the slider, as shown in fig. 3, the spring 32 is inserted into the insertion cavity 29 through the spring groove 25 of the slide passage 23. The base plate 51 of the closure member 20 is then inserted into the slide channel 23 and advanced along the channel until the opposing side arms 52 of the closure member 20 retain the spring 32 therebetween. After the closure member 20 has advanced beyond the tabs 30 disposed on opposite sides of the slide channel 32, the tabs 30 are staked against the slide channel 32, thus preventing the closure member 20 from disengaging from the slide channel 32.

To attach the pull tab 2 to the slider body 1 thus assembled, as shown in fig. 4, the pair of projecting walls 5 of the pull tab body 4 is slid forward from the gap 47 on the upper wing 15, and the notch 8 of the pull tab body 4 is aligned with the pull tab attaching pull tab seat 18, so that the pulling shaft 6 of the pull tab 2 contacts the closing member 20 and pushes it forward. The pulling shaft 6 is further advanced, and the closing member 20 is pushed against the elastic force of the spring 32, so that the pulling shaft 6 enters the pull tab hole 46 of the pull tab seat 18, and the pull tab hole 46 of the pull tab seat 18 directly receives the pull tab 2. The pull tab 2 is now attached to the slider body 1. The pull tab 2 according to the second embodiment is the same in operation method as the pull tab according to the first embodiment. However, since the length of the tab hole 46 of the tab holder 18 is longer, the tab 2 moves back and forth a longer distance, so that the middle portion of the projecting wall 5 contacts the end point of the slider body 1 and the corner 9 of the projecting wall 5 easily contacts the fastener element row. In order to prevent the corners 9 of the projecting wall 5 from contacting the rows of zipper teeth, the projecting wall 5 should be made shorter as described above. Alternatively, the corners 9 of the projecting wall 5 may be formed as arcuate or chamfered chamfers. Alternatively, the pull tab hole 46 of the pull tab seat 18 may be made shorter, thus shortening the distance of the reciprocating motion of the pulling shaft 6 of the pull tab 2. To replace the pull tab, the closing element 20 is pushed by a pointed tool deep into the pull tab hole 46 of the pull tab seat 18, thus opening the gap 47. Subsequently, the pulling shaft 6 of the pull tab 2 is released from the pull tab hole 46 of the pull tab seat 18 through the gap 47, so that the pull tab 2 can be replaced.

The pull tab 2 according to the present invention can be easily applied to various sliders of a type in which the pull tab is to be reattached to the slider body after the slide fastener is shipped from the factory. For example, it may also be applied to a free slider (although not shown in the drawings) of the type described above, in which, unlike the slider body in the above-described embodiment, the proximal end of the C-shaped pull tab attachment base may be mounted in a cantilevered fashion on the upper wing at the rear end of the slider body, with its distal end extending forwardly. In this slider, the closing member and the coil spring are mounted one above the other in a vertical groove formed in a guide post provided at the front end of the slider body. The closing member is normally urged upward by a coil spring therebelow, thus closing a gap defined between the distal end of the pull tab holder and the slider body. The pull tab body is inserted into the pull tab hole of the pull tab attaching pull tab seat of the slider body from the guide post end.

Conclusion, consequences and scope

Therefore, the pull tab can be attached to the slider body very easily, and various decorative patterns can be applied to the upper surface of the pull tab body easily, enabling the production of an aesthetically appealing slider, and the easy replacement of the pull tab even when the slide fastener has been used.

Further, the pull tab can be stably inserted and attached to the pull tab attaching pull tab seat of the two types of sliders, i.e., the automatic locking slider and the free slider. Especially for the automatic locking slider, the locking part loaded with the spring can stably push the pull tab body to abut against the slider body, so that the pull tab body is stably kept on the slider body.

In addition, the pull tab body can pivot back and forth and left and right, so that the pull tab can be pulled smoothly.

The zipper slider according to the present invention is used to close openings formed in garments and bags of the type which are important for decoration. The slider has an aesthetically designed pull tab that appears as a decorative button. The slider is now equipped with a mechanism to allow the garment and bag to be freely attached and replaced with decorative fancy pull tabs during use.

While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but as merely providing illustrations of some of the presently preferred embodiments of this invention.

Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
