Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The wet suit 6, which is an article of this embodiment, is cut in the back portion of its upper half portion from the neck portion up to the waist portion such that its two sections are separated, and a waterproof slide fastener 1 is attached along the cut-in portion. In the slide fastener 1, an engagement gap to mating fastener elements 21 is produced along element attaching edge portions 11 which are opposing edge portions of a pair of waterproof fastener tapes 10, so that a plurality of fastener elements 21 are molded integrally on each side so as to form right and left fastener element rows 20. In the slide fastener 1, a top end stop (not shown) is respectively attached near the end portion of the fastener element 21 on the side of the neck portion of each fastener element row 20 formed on opposing a pair of fastener stringers 2. In addition, a single bottom end stop 3 is attached to the end portion on the side of the waist portion near the fastener elements 21 in an engaged state. The top end stop has a function which blocks the slider 4 from being loosed out at the end portion when the slide fastener 1 is closed, and the bottom end stop 3 has a function which blocks the slider 4 from being loosed out at the end portion when the slide fastener 1 is opened. A slider 4 made of synthetic resin or metal having an ordinary function is loaded on the fastener element row 20 between the top end stop and the lower end stop 3, the fastener element row 20 being inserted therethrough.
The waterproof slide fastener 1 applied to this embodiment is an ordinary waterproof slide fastener, and the slider used in the fastener has an ordinary structure. That is, as shown in
As shown in
On the other hand, the fastener element 21 comprises a coupling head 22 providing an oval shape slightly elongated in a vertical direction (in the longitudinal direction of the fastener) as seen in a plan view, a body portion 24 providing a substantially hexagonal shape as seen in a plan view, continuous from the coupling head 22 via a neck portion 23, wing-like shoulder portions 25 extending to the right and left sides between the neck portion 23 and the body portion 24, and leg portions 27 extending downward from the bottom end of the body portion 24 such that they are branched via a crotch portion 26. The fastener element 21 having such a configuration is constituted of half portions 21a, 21b which are connected integrally through a connecting portion 21c molded in the through hole 14 such that it sandwiches the element attaching edge portion 11 of the fastener tape 10, the half portions being molded on the front and rear faces of the fastener tape 10. In the meantime, the shoulder portion 25 may be omitted.
Respective half portions 22a, 22b; 23a, 23b; 24a, 24b; 25a, 25b; and 27a, 27b of the coupling head 22, the neck portion 23, the body portion 24, the shoulder portion 25 and the leg portion 27 are molded integrally in symmetrical shape sandwiching the fastener tape 10 on the front and rear sides of the fastener tape 10. The respective half portions 23a, 23b; 24a, 24b; 25a, 25b; and 27a, 27b excluding the coupling head 22 are integrated by welding on both the front and rear faces of the fastener tape 10.
The half portions 22a, 22b of the coupling head 22 molded symmetrically on the front and rear sides and sandwiching the fastener tape 10 are provided such that they extend to right and left outward from an edge 11a with a gap corresponding to the thickness of about one sheet of fastener tape 10 secured therebetween in a state in which the edge 11a of the element attaching edge portion 11 of the fastener tape 10 is exposed slightly outward as shown in
The thickness of each half portion 23a, 23b; 24a, 24b of the neck portion 23 and the body portion 24 is the largest, and the thickness of each half portion 25a, 25b; 27a, 27b of the shoulder portion 25 and the leg portion 27 is smaller than the thickness of the each half portion 23a, 23b; 24a, 24b of the neck portion 23 and the body portion 24 as shown in
In this embodiment, the waterproof slide fastener 1 having the above-described configuration is attached to the wet suit 6 as shown in
In this embodiment, as shown in
Further, according to the present invention, the covering tape 16 which is a characteristic portion of the present invention is attached to an area covering at least the bottom end stop 3 and a portion from the bottom end stop 3 up to the connecting member 15. As shown in
According to the present invention, a pressing tape piece 17, which constitutes another characteristic portion of the present invention, is provided between the connecting member 15 and the covering tape 16.
The pressing tape piece 17 is disposed along the longitudinal direction of the covering tape 16 crosswise to the connecting member 15 such that it strides over the connecting member 15 whose both end portions are welded to the rear face of the right and left fastener stringers 2 from the fastener stringer 2 side, and the both end portions thereof are fixed to the rear face of the covering tape by welding. Further, it may be attached by sewing. Although the pressing tape piece 17 may be fixed to the connecting member 15, the pressing tape piece 17 does not always need to be fixed to the connecting member 15 when attempt is made to set the connecting member 15 movable freely between the fixed portions on the both ends of the pressing tape 17. The central portion of the connecting member 15 may be fixed directly to the rear face of the covering tape 16 without using the pressing tape piece 17.
When a user tries to put on or put off the wet suit of this embodiment having the above-described configuration by sliding the slider upward or downward, the cut-in portion 6a of the wet suit 6 is opened largely together with the right and left fastener stringers 2. As a consequence, an extremely large force is applied to the wet suit 6 and a so-called tearing force is applied to the slide fastener 1. Unless the connecting member 15 is attached, the force is transmitted directly to the slider, so that a portion of the fastener tape 10 or the fastener element 21 existing on the side of the element diamond 4c within an inside passage of the slider 4 makes a firm contact with the slider 4 and is damaged, thereby possibly damaging the slider itself. Further, if the aforementioned strong force which attempts to open the slide fastener 1 is applied, the slider 4, in particular, comes to press the bottom end stop 3 attached to the terminal end on the lower side with a strong force. Consequently, the bottom end stop 3 fixed to the right and left fastener stringers 2 is deformed or its attachment position is deflected, so that it may drop out of the slide fastener 1 depending on circumstances.
According to this embodiment, however, the both end portions of the connecting member 15 are fixed to the right and left fastener stringers 2 at a position above the bottom end stop 3 so as to connect between the stringers 2. For this reason, the aforementioned external strong force is transmitted to the connecting member 15 and received thereby in a straightly stretched state. Consequently, the force is not transmitted to the slider 4 and the fastener tape portion and the fastener element portion existing in the inside passage of the slider 4 to thereby prevent the above-described damage. Moreover, because the aforementioned force is not applied between the fastener stringer 2 and the slider 4, the sliding operation of the slider 4 can be executed smoothly.
In this embodiment, as described above, at least one side edge portion of the covering tape 16 is fixed to the rear face of the wet suit, and the both end portions of the pressing tape piece 17 are fixed to the rear face of the covering tape 16 on the side of the wet suit such that it strides over the front surface side of the connecting member 15 which connects the right and left fastener stringers 2. Consequently, the connecting member 15 is always pressed to the side of the covering tape 16, and when the slider 4 passes through a space between the connecting member 15 and the right/left fastener stringers 2, a sufficient space for the lower blade 4b of the slider 4 to pass is secured between the connecting member 15 and the fastener stringer 2, because the connecting member 15 is integrated with the covering tape 16 in a state in which the connecting member 15 is pressed against the covering tape 16. Accordingly, the slider 4 can be slid smoothly without the connecting member 15's being hooked or caught by the slider 4.
Particularly, in this embodiment, the shape of the connecting member 15 is fixed by folding a straight long tape into a U-like shape and setting with heat. For this reason, when a pair of the fastener stringers 2 are opened to the right and left, the U-like shape is changed to a straight shape although the connecting member 15 maintains its U-like shape with the slide fastener 1 closed. Thus, even if a large tearing force is applied to the pair of fastener stringers 2 as shown in
Right and left flanges 104a-1 are erected on right and left ends of the lower blade 104a, and eaves portions 104a-2 extending to approach each other are formed at the free ends of the respective flanges 104a-1, so that a space surrounded by the element diamond 104b, the flanges 104a-1 and the eaves portions 104a-2 constitute an element guide space. In the fastener stringer 102 having the above-described structure, with the bent end portions of the fastener tape 110 and the fastener elements 121 attached to the end portions accommodated in the element guide space, the fastener tape 110 is introduced out through a gap between the element diamond 104b and the eaves portions 104a-2. When the fastener elements are engaged to close the slide fastener 101, the bent end portions of the right and left fastener tapes 110 make contact with each other, and only the pull tag supporting ring 104c and the pull tag 105 of the slider 104 are exposed out while other portions of the slider 104 are concealed on the rear side of the slide fastener 101.
This kind of the concealed type slide fastener is often used for women's clothes such as one-piece dress and skirt. In this kind of the women's clothes, the slide fastener 10 is often attached from its neck portion to the waist portion or from the waist portion to the hip portion. As a result, the slide fastener must be opened or closed by operating the slider 104 in an invisible state. Particularly, the body line changes at a portion from the waist portion to the hip portion, and clothes which the user wears is often produced to trace along the body line. Thus, when the user puts on or puts off such clothes, a strong tearing force is applied to the slide fastener like the above-mentioned wet suit. For this reason, in this embodiment also, the connecting member 15, the covering tape 16 and the pressing tape piece 17 are attached to the rear face of the clothes 106 like the first embodiment. In the meantime, same reference numerals are attached to components substantially coinciding with the components used in the first embodiment.
Also in this embodiment, as shown in
The attachment position of the connecting member 15 is the same as that in the first embodiment, and the attachment position and attachment structure of the pressing tape piece 17 are the same as those in the first embodiment. Therefore, the operating effect achieved thereby is substantially the same as the operating effect of the first embodiment. In the second embodiment, because the object article is women's clothes, a generally plastic and thin fabric material is used and thus, a plastic and high tensile strength material needs to be used for the connecting member 15 and the pressing tape piece 17. To meet such a demand, multi-filament of synthetic fiber, particularly fabric composed of textured multi-filament is preferable, and other materials may be used as required.
The slide fastener 201 of this embodiment is different from the waterproof slide fastener of the first embodiment in terms of a portion of an end stop 203. Thus, same reference numerals are used for substantially the same members or parts as those in the first embodiment.
The end stop 203 of this embodiment is provided striding over the right and left fastener tapes 10 adjacent the right and left fastener elements 21 disposed at upper and lower terminal ends of the element row 20 shown in
In the
A linearly extending stopper portion 203c is provided striding over the right and left fastener tapes 10 on a bottom portion corresponding to the bent portion of the U-shaped plan portion of the reinforcement area 203a. The thickness of the stopper portion 203c projecting from the front and rear faces of the fastener tape 10 is equal to or larger than the interval of a shoulder mouth formed between the upper and lower blades 4a, 4b of the slider 4.
Assume that the slide fastener 201 having the above-described configuration is loaded on a bag (not shown) of this embodiment. When the slider 4 of the slide fastener 201 is slid toward the end stop 203, the end stop 203 is guided to the shoulder mouth of the slider 4 by the element diamond 4c and introduced into the element guide passage while the right and left end portions of the end stop 203 are expanded. Here, the inside face of a bottom portion 203b-1 of the projection 203b of the end stop 203 is fit to the shoulder mouth side end face of the diamond 4c of the slider 4, and at the same time, the projection 203b is fit to the peripheral face of the element diamond of the slider 4 while making a firm contact with the inside faces of the upper and lower blades 4a, 4b. This prevents rainfall water or the like from invading from outside. Even if a strong external force is applied to an opening portion of the bag and then a strong tearing force is applied to the fastener tape 10, the tearing force is not transmitted directly to the slider 4 because the connecting member 15, the covering tape and pressing tape piece (not shown) are attached. Further, the slider operation is carried out smoothly.
Although the fastener elements of the above embodiment are molded integrally on the fastener tape by injection molding of a synthetic resin, of course, the fastener element of the present invention is not restricted to the above embodiments and may be of a coil-like element made of synthetic resin or metal.
