- Japanese Patent No. 3380150 Japanese Patent No. 3380150 (patent document 2) has disclosed a seat in which a slide fastener is used at a seat cover of a seat back.
- a seat 81 described in this patent document 2 is comprised of a seat cushion 82 and a seat back 83 as shown in FIG. 16 .
- These components 82 , 83 have a seat frame (not shown), a pad (not shown) having a predetermined shape to be fixed to the seat frame, and skins 86 , 87 for covering the pad.
- the pad is formed of polyurethane or the like, having cushion performance.
- the skin 87 of the seat back 83 has a cutout 88 extending upward from the bottom edge of the seat rear face, and a skin rear face portion 87 a is so formed to be separable to its right and left sections with the cutout 88 interposed therebetween.
- a slide fastener 89 is sewed along the cutout 88 formed on the skin rear face portion 87 a .
- One end portion of the slide fastener 89 is extended downward longer than a bottom edge 87 b of the skin rear face portion 87 a .
- One of the right and left fastener stringers is sewed to the skin 87 so that the stringer is hidden invisibly from outside by folding the skin 87 extending from the skin bottom edge 87 b to the back side.
- the skin 87 is applied to the pad of the seat back 83 in a state that the skin rear face portion 87 a is separated to the right and left sections by opening the slide fastener 89 , and thereafter, the slider 92 is slid to close the slide fastener 89 , so that the skin 87 can be fitted to the pad in a good appearance.
- one of the fastener stringers of the slide fastener 89 is sewed such that the portion extending downward form the skin bottom edge 87 b is hidden on the skin back side.
- the extending portion of the other fastener stringer is folded to the skin back side and hidden there. Consequently, when the slide fastener 89 is closed, the end portion on the extending portion side of the slide fastener 89 is held at a predetermined position on the skin back side.
- the extending portion of the slide fastener 89 is difficult to peel from the skin back side even if, for example, the fingers of a passenger seated on the seat 81 are hooked on the slide fastener 89 by a mistake.
- the closing state of the slide fastener 89 can be maintained in a stable state.
- the grip portion of the slider is constructed of a belt-like body such as fabric having a surface fastener to facilitate gripping of the pull tab and is also disposed such that the front and rear faces of the grip portion are oriented in a lateral direction with respect to the sliding direction of the slider.
- the connecting portion of the slider is supported on the slider body rotatably along the sliding direction of the slider with respect to the first attaching portion on the slider body side so that a user can slide the slider smoothly along the element rows by gripping the grip portion.
- this connecting portion is formed of a metal member which hardly cracks in order to securely connect the slider body with the pull tab in a long period.
- the pull tab of the slider is attached considering the operability and the like of the slider, there is such a problem that when the slider is not operated, the metal slider body comes into contact with the connecting portion of the pull tab so as to produce a metallic clank offensive to the ears.
- the slide fastener is used in, for example, a seat cover of vehicle seats as disclosed in the patent document 2, the slider body frequently comes into contact with the pull tab due to vibration during traveling of the vehicle and further when the slider swings, the slider body and the pull tab come into contact with other members such as a seat frame, thereby producing contact sound.
- the slider 92 may be hidden on the skin back side by closing the slide fastener 89 . Even in such a case, if the portion hidden by the slide fastener 89 (portion extending form the skin bottom edge 87 b ) is short, the pull tab of the slider 89 rotates around the slider body, so that part of the pull tab sometimes might project out so that the part of the pull tab droops from the bottom edge 87 b . If the pull tab of the slider 89 is exposed, the appearance of the slider is bad and the pull tab is easily hooked by other members, thereby causing a fear that the slider may be operated by a mistake.
- the present invention provides a slider for a slide fastener in which an upper blade and a lower blade are connected by a guiding post at a front end portion on a shoulder mouth side while a slider body having a rear mouth is provided at the rear end, being characterized by further including: a gate-shaped pull tab attaching post having right and left leg portions erected from the upper blade and apart from each other in a transverse direction of the slider body and a bridge portion stretched between the top end portions of the right and left leg portions, the pull tab attaching post being formed integrally with the slider body; and a pull tab, one end of which is attached to the bridge portion, the pull tab extending from the bridge portion.
- the slider body is preferably composed of a synthetic resin.
- the slider of the present invention further includes rotation blocking means for blocking a post attaching portion for the pull tab to be attached to the bridge portion from rotating around the bridge portion.
- the rotation blocking means is constituted of a tongue piece projecting from the bridge portion.
- the rotation blocking means may be constructed by fixing the pull tab to the bridge portion.
- the pull tab is preferably bendable elastically.
- the pull tab may be composed of a hard synthetic resin.
- the pull tab is formed of a narrow thin piece having first and second pull tab main body portions disposed in the back-forth direction of the slider and a folding portion which connects the first and second pull tab main body portions, and that the first and second pull tab main body portions have surface fastener engaging elements disposed on at least part of each of first surfaces which oppose each other when the pull tab is folded at the folding portion.
- the first pull tab main body portion is formed longer than the second pull tab main body portion, and male engaging elements of a surface fastener are disposed in area of the first surface of the first pull tab main body portion other than a portion thereof the second pull tab main body portion overlaps when the first and second pull tab main body portions are engaged with each other.
- the pull tab is attached such that the first surface of the first pull tab main body portion faces downward when the pull tab is extended to the shoulder mouth side of the slider body from the bridge portion.
- the slider for a slide fastener of the present invention includes a slider body, a gate-shaped pull tab attaching post formed integrally on an upper blade of the slider body in a symmetrical configuration, and a pull tab made of a belt-like body one end of which is attached to a bridge portion of the pull tab attaching post.
- the pull tab attaching post includes right and left leg portions erected from the upper blade and apart from each other in the transverse direction of the slider body, and the bridge portion which is stretched between the top end portions of the right and left leg portions.
- the pull tab is extended in the back-forth direction of the slider from the bridge portion of the gate-shaped pull tab attaching post disposed in the right-left direction, and the front and rear faces of the pull tab are oriented in a lateral direction with respect to the sliding direction of the slider. Consequently, the pull tab of the slider is easy to grip and the slider can be operated easily, thereby securing an excellent operability.
- one end of the pull tab is attached directly to the pull tab attaching post without use of any metallic connecting member like a conventional example.
- generation of contact sound can be prevented effectively even if the pull tab comes into contact with the slider body or other member.
- the slider body is made of a synthetic resin or the pull tab is made of a belt-like body in the present invention, generation of the sound due to a contact between the slider body and the pull tab can be prevented securely. Even if the slider body comes into contact with other members, generation of the contact sound can be prevented effectively.
- the post attaching portion for the pull tab to be attached to the bridge portion has the rotation blocking means for blocking the rotation around the bridge portion. Consequently, the direction of the pull tab when the slider is not operated can be limited to a certain direction. Thus, the pull tab can be prevented from dangling and the pull tab can be prevented from coming into contact with the slider body or other members.
- the direction of the pull tab when the slide fastener is closed can be specified to a predetermined one, for example, if the slide fastener is used in a seat cover of a vehicle seat. Consequently, when the slider is hidden on the back side of the seat cover, the pull tab does not jump out from the back side of the seat cover even if the slider receives a vibration or the like of the vehicle, whereby the pull tab can be hidden securely. Accordingly, the closing state of the slider fastener can be maintained stably.
- the rotation blocking means can be easily constructed of the tongue piece projecting from the bridge portion, or can be easily constructed by fixing the pull tab to the bridge portion. If the tongue piece is formed as the rotation blocking means, the direction of the pull tab when the slider is not operated can be oriented in its predetermined direction easily by projecting the tongue piece in a predetermined direction from the bridge portion, for example, to the shoulder mouth side or rear mouth side in parallel to the upper blade.
- the pull tab is constructed to be bendable elastically. Consequently, the direction of the pull tab can be oriented easily to the sliding direction of the slider when the slider is slid along element rows, so that the slider can be operated smoothly. If the slider has the rotation blocking means, the pull tab can be oriented to a predetermined direction which is limited by the rotation blocking means when the pull tab is released from the fingers.
- the pull tab may be composed of a hard synthetic resin. Consequently, the pull tab can be constructed to be easy to grip, whereby the sliding operation of the slider can be carried out easily.
- the pull tab of the slider of the present invention is constructed of a narrow thin piece comprised of the first and second pull tab main body portions disposed in the back-forth direction of the slider and the folding portion which connects these. Further, the first and second pull tab main body portions have engaging elements of a surface fastener which can engage each other on at least part of each of the first faces. As a result, the pull tab can be manufactured at a low cost and the pull tab can be easily attached to the pull tab attaching post.
- the first pull tab main body portion in the present invention is formed longer than the second pull tab main body portion, and male engaging elements of a surface fastener are disposed in area of the first surface of the first pull tab main body portion other than a portion thereof the second pull tab main body portion overlaps when the first and second pull tab main body portions are engaged with each other.
- the slider can be fixed at a predetermined position by engaging the male engaging elements disposed on the first face of the first pull tab main body portion with the back side of the seat cover.
- the slider can be prevented from dangling freely, so that the slider can be prevented from coming into contact with the seat frame or the like of the vehicle seat, thereby blocking generation of a contact sound securely. Even if the slider receives a vibration or the like of the vehicle, it never slides freely along the element rows, whereby the closing state of the slide fastener can be maintained stably.
- the pull tab is preferably attached such that the first face of the first pull tab main body portion faces downward (upper blade side). Consequently, when the slider is hidden on the back side of the seat cover, the male engaging elements of the first pull tab main body portion can be easily engaged with the seat cover back side, whereby the slider can be fixed at a predetermined position securely.

Description
- 1. Field of the Invention
- The present invention relates to a slider for a slide fastener, capable of reducing sound generated by a contact between a slider body and a pull tab.
- 2. Description of the Related Art
- Conventionally, a slide fastener is attached to an opening in order to easily open/close the opening in clothes, bag or the like. Generally, the slide fastener is constructed by arranging a plurality of fastener elements on each of element attaching edge portions opposing each other of right and left fastener tapes so as to form a pair of right and left fastener stringers, and then placing a slider on the right and left element rows composed of the plurality of fastener elements disposed on the right and left fastener stringers.
- A slider has a slider body to be placed on the element rows and a pull tab attached to the slider body. The slider body is often made of metal and generally, includes upper and lower blades, a connecting post for connecting the upper and lower blades at a front end portion of the slider, right and left flanges formed on right and left side edges of the upper blade and/or the lower blade, and a pull tab attaching post erected on the surface (top surface) of the upper blade along the back-forth direction of the slider.
- Right and left shoulder mouths are formed on the front end side of the slider body such that they are divided by the connecting post while a rear mouth is formed at a rear end of the slider body. Further, a Y-shaped element guide passage which brings the right and left shoulder mouths and the rear mouth in communication with each other is disposed between the upper and lower blades. The pull tab has a connecting portion for connecting one end thereof to the pull tab attaching post provided on the slider body and a grip portion disposed on the other end of the connecting portion.
- An example of the slide fastener having such a configuration is described in European Patent No. 761117 (patent document 1). In a
slide fastener 71 described in thepatent document 1, as shown inFIG. 14 , aslider 74 is placed on element rows 73 of the pair of right andleft fastener stringers 72. Theslider 74 in thispatent document 1 includes aslider body 75 and apull tab 76. Theslider body 75 includes an upper blade, a lower blade, a connecting post, right and left flanges, and an inverted U-shaped pulltab attaching post 75 a. - The
pull tab 76 has a connectingbody 77 and agrip portion 78. The connectingportion 77 includes a first attachingportion 77 a which is constituted of a hole portion formed at one end portion thereof and a second attachingportion 77 b which is composed of a ring-like limb disposed at the other end portion thereof. In this case, the connectingbody 77 is installed onto theslider body 75 by inserting the first attachingportion 77 a into the inverted U-shaped pulltab attaching post 75 a disposed on theslider body 75 in a cantilevered state such that the attachingpost 75 a is hooked on theslider body 75, and thereafter deforming the pulltab attaching post 75 a plastically so that the connectingbody 77 does not slip out of the pulltab attaching post 75 a. - On the other hand, the
grip portion 78 has a first main body portion (surface half portion) 78 a, a second main body portion (rear surface half portion) 78 b, and aneck portion 78 c for connecting the first and secondmain body portions main body portion 78 a of thegrip portion 78 has a plurality ofloops 78 d which constitute a surface fastener, and the first surface (inner side face) of the secondmain body portion 78 b has a plurality ofhooks 78 e which constitute a surface fastener. - The
grip portion 78 having the plurality ofloops 78 d and the plurality ofhooks 78 e is installed onto the connectingbody 77 by overlapping the firstmain body portion 78 a and the secondmain body portion 78 b after the firstmain body portion 78 a or the secondmain body portion 78 e is inserted into the second attaching portion (limb) 77 b of the connectingbody 77 so as to engage thehooks 78 e of the secondmain body portion 78 b with theloops 78 d of the firstmain body portion 78 a. - The
slide fastener 71 of thepatent document 1 can be manufactured at a lower cost than, for example, a slide fastener using a rivet for attaching thegrip portion 78. Thegrip portion 78 can be formed into a desired shape by, for example, cutting out the surface fastener into a predetermined shape. Thus, thegrip portion 78 can have ample variations, and further various patterns or logo marks, etc. can be provided on the front surface or the rear surface (second surface of the first main body portion and the second main body portion) of thegrip portion 78. - Generally, the slide fasteners have been used at an opening of clothes or bags, etc., and in recent years, they have been often used in seat covers of passenger seats of vehicles or the like. For example, Japanese Patent No. 3380150 (patent document 2) has disclosed a seat in which a slide fastener is used at a seat cover of a seat back.
- A
seat 81 described in thispatent document 2 is comprised of aseat cushion 82 and aseat back 83 as shown inFIG. 16 . Thesecomponents skins - According to the
patent document 2, theskin 87 of theseat back 83 has acutout 88 extending upward from the bottom edge of the seat rear face, and a skinrear face portion 87 a is so formed to be separable to its right and left sections with thecutout 88 interposed therebetween. Aslide fastener 89 is sewed along thecutout 88 formed on the skinrear face portion 87 a. When theslider 92 of theslide fastener 89 is slid downward, right andleft elements 91 are coupled with each other so as to close thecutout 88. - One end portion of the
slide fastener 89 is extended downward longer than abottom edge 87 b of the skinrear face portion 87 a. One of the right and left fastener stringers is sewed to theskin 87 so that the stringer is hidden invisibly from outside by folding theskin 87 extending from theskin bottom edge 87 b to the back side. - In the
seat 81 described in thepatent document 2, theskin 87 is applied to the pad of the seat back 83 in a state that the skinrear face portion 87 a is separated to the right and left sections by opening theslide fastener 89, and thereafter, theslider 92 is slid to close theslide fastener 89, so that theskin 87 can be fitted to the pad in a good appearance. - Particularly in the
seat 81 of thepatent document 2, one of the fastener stringers of theslide fastener 89 is sewed such that the portion extending downward form theskin bottom edge 87 b is hidden on the skin back side. Thus, when theslide fastener 89 is closed, the extending portion of the other fastener stringer is folded to the skin back side and hidden there. Consequently, when theslide fastener 89 is closed, the end portion on the extending portion side of theslide fastener 89 is held at a predetermined position on the skin back side. - For the reason, in the
skin 87 applied to the pad of theseat 81, the extending portion of theslide fastener 89 is difficult to peel from the skin back side even if, for example, the fingers of a passenger seated on theseat 81 are hooked on theslide fastener 89 by a mistake. Thus, the closing state of theslide fastener 89 can be maintained in a stable state. - In the conventional slide fastener of the
patent document 1, the grip portion of the slider is constructed of a belt-like body such as fabric having a surface fastener to facilitate gripping of the pull tab and is also disposed such that the front and rear faces of the grip portion are oriented in a lateral direction with respect to the sliding direction of the slider. The connecting portion of the slider is supported on the slider body rotatably along the sliding direction of the slider with respect to the first attaching portion on the slider body side so that a user can slide the slider smoothly along the element rows by gripping the grip portion. Further, this connecting portion is formed of a metal member which hardly cracks in order to securely connect the slider body with the pull tab in a long period. - Although in the conventional slide fastener, the pull tab of the slider is attached considering the operability and the like of the slider, there is such a problem that when the slider is not operated, the metal slider body comes into contact with the connecting portion of the pull tab so as to produce a metallic clank offensive to the ears. If the slide fastener is used in, for example, a seat cover of vehicle seats as disclosed in the
patent document 2, the slider body frequently comes into contact with the pull tab due to vibration during traveling of the vehicle and further when the slider swings, the slider body and the pull tab come into contact with other members such as a seat frame, thereby producing contact sound. - Generation of such contact sound due to a contact between the slider body and the pull tab or a contact thereof with other members can be reduced to some extent by forming the slider body and the connecting portion of the pull tab with a synthetic resin molded product. However, it is demanded to prevent the generation of the contact sound effectively in order to improve the quality of the slide fastener further.
- Preventing the generation of the contact sound in the slider body and the pull tab without reduction of the operability of the slider has been demanded on a slide fastener for use in baby clothes, infant clothes, nursing care clothes and the like in which the contact sound is offensive to the ears as well as the slider fastener for use in the seat cover of the above-mentioned vehicle seats.
- When the
slide fastener 89 is used in the skin (seat cover) 87 or the like of thevehicle seat 81 as described in thepatent document 2, theslider 92 may be hidden on the skin back side by closing theslide fastener 89. Even in such a case, if the portion hidden by the slide fastener 89 (portion extending form theskin bottom edge 87 b) is short, the pull tab of theslider 89 rotates around the slider body, so that part of the pull tab sometimes might project out so that the part of the pull tab droops from thebottom edge 87 b. If the pull tab of theslider 89 is exposed, the appearance of the slider is bad and the pull tab is easily hooked by other members, thereby causing a fear that the slider may be operated by a mistake. - The present invention has been achieved in views of the above-mentioned conventional problems, and an object of the invention is to provide a slider for a slide fastener capable of preventing generation of sound even when, for example, it is used in a seat cover of a vehicle seat by reducing contact sound generated from a slider body or a pull tab. Another object of the present invention is to provide a slider for a slide fastener which can be securely hidden on the back side of a seat cover when a slide fastener is used in the seat cover or the like.
- To achieve the above-described object, the present invention provides a slider for a slide fastener in which an upper blade and a lower blade are connected by a guiding post at a front end portion on a shoulder mouth side while a slider body having a rear mouth is provided at the rear end, being characterized by further including: a gate-shaped pull tab attaching post having right and left leg portions erected from the upper blade and apart from each other in a transverse direction of the slider body and a bridge portion stretched between the top end portions of the right and left leg portions, the pull tab attaching post being formed integrally with the slider body; and a pull tab, one end of which is attached to the bridge portion, the pull tab extending from the bridge portion.
- In the slider for a slide fastener of the present invention, the slider body is preferably composed of a synthetic resin.
- Preferably, the slider of the present invention further includes rotation blocking means for blocking a post attaching portion for the pull tab to be attached to the bridge portion from rotating around the bridge portion. In this case, it is preferable that the rotation blocking means is constituted of a tongue piece projecting from the bridge portion. The rotation blocking means may be constructed by fixing the pull tab to the bridge portion.
- In the slider of the present invention, the pull tab is preferably bendable elastically. Alternatively, the pull tab may be composed of a hard synthetic resin.
- It is preferable that the pull tab is formed of a narrow thin piece having first and second pull tab main body portions disposed in the back-forth direction of the slider and a folding portion which connects the first and second pull tab main body portions, and that the first and second pull tab main body portions have surface fastener engaging elements disposed on at least part of each of first surfaces which oppose each other when the pull tab is folded at the folding portion.
- In this case, preferably, the first pull tab main body portion is formed longer than the second pull tab main body portion, and male engaging elements of a surface fastener are disposed in area of the first surface of the first pull tab main body portion other than a portion thereof the second pull tab main body portion overlaps when the first and second pull tab main body portions are engaged with each other. Particularly, it is preferable that the pull tab is attached such that the first surface of the first pull tab main body portion faces downward when the pull tab is extended to the shoulder mouth side of the slider body from the bridge portion.
- The slider for a slide fastener of the present invention includes a slider body, a gate-shaped pull tab attaching post formed integrally on an upper blade of the slider body in a symmetrical configuration, and a pull tab made of a belt-like body one end of which is attached to a bridge portion of the pull tab attaching post. The pull tab attaching post includes right and left leg portions erected from the upper blade and apart from each other in the transverse direction of the slider body, and the bridge portion which is stretched between the top end portions of the right and left leg portions.
- In the slider of the present invention having such a configuration, the pull tab is extended in the back-forth direction of the slider from the bridge portion of the gate-shaped pull tab attaching post disposed in the right-left direction, and the front and rear faces of the pull tab are oriented in a lateral direction with respect to the sliding direction of the slider. Consequently, the pull tab of the slider is easy to grip and the slider can be operated easily, thereby securing an excellent operability.
- In the slider of the present invention, one end of the pull tab is attached directly to the pull tab attaching post without use of any metallic connecting member like a conventional example. Thus, generation of contact sound can be prevented effectively even if the pull tab comes into contact with the slider body or other member. Particularly, if the slider body is made of a synthetic resin or the pull tab is made of a belt-like body in the present invention, generation of the sound due to a contact between the slider body and the pull tab can be prevented securely. Even if the slider body comes into contact with other members, generation of the contact sound can be prevented effectively.
- In the slider of the present invention, the post attaching portion for the pull tab to be attached to the bridge portion has the rotation blocking means for blocking the rotation around the bridge portion. Consequently, the direction of the pull tab when the slider is not operated can be limited to a certain direction. Thus, the pull tab can be prevented from dangling and the pull tab can be prevented from coming into contact with the slider body or other members.
- By limiting the direction of the pull tab to a certain direction, the direction of the pull tab when the slide fastener is closed can be specified to a predetermined one, for example, if the slide fastener is used in a seat cover of a vehicle seat. Consequently, when the slider is hidden on the back side of the seat cover, the pull tab does not jump out from the back side of the seat cover even if the slider receives a vibration or the like of the vehicle, whereby the pull tab can be hidden securely. Accordingly, the closing state of the slider fastener can be maintained stably.
- In this case, the rotation blocking means can be easily constructed of the tongue piece projecting from the bridge portion, or can be easily constructed by fixing the pull tab to the bridge portion. If the tongue piece is formed as the rotation blocking means, the direction of the pull tab when the slider is not operated can be oriented in its predetermined direction easily by projecting the tongue piece in a predetermined direction from the bridge portion, for example, to the shoulder mouth side or rear mouth side in parallel to the upper blade.
- In the slider of the present invention, the pull tab is constructed to be bendable elastically. Consequently, the direction of the pull tab can be oriented easily to the sliding direction of the slider when the slider is slid along element rows, so that the slider can be operated smoothly. If the slider has the rotation blocking means, the pull tab can be oriented to a predetermined direction which is limited by the rotation blocking means when the pull tab is released from the fingers. The pull tab may be composed of a hard synthetic resin. Consequently, the pull tab can be constructed to be easy to grip, whereby the sliding operation of the slider can be carried out easily.
- The pull tab of the slider of the present invention is constructed of a narrow thin piece comprised of the first and second pull tab main body portions disposed in the back-forth direction of the slider and the folding portion which connects these. Further, the first and second pull tab main body portions have engaging elements of a surface fastener which can engage each other on at least part of each of the first faces. As a result, the pull tab can be manufactured at a low cost and the pull tab can be easily attached to the pull tab attaching post.
- In this case, the first pull tab main body portion in the present invention is formed longer than the second pull tab main body portion, and male engaging elements of a surface fastener are disposed in area of the first surface of the first pull tab main body portion other than a portion thereof the second pull tab main body portion overlaps when the first and second pull tab main body portions are engaged with each other. As a result, for example, in case where the slide fastener is used in the seat cover of the vehicle seat and the slider is hidden on the back side of the seat cover, the slider can be fixed at a predetermined position by engaging the male engaging elements disposed on the first face of the first pull tab main body portion with the back side of the seat cover. Therefore, the slider can be prevented from dangling freely, so that the slider can be prevented from coming into contact with the seat frame or the like of the vehicle seat, thereby blocking generation of a contact sound securely. Even if the slider receives a vibration or the like of the vehicle, it never slides freely along the element rows, whereby the closing state of the slide fastener can be maintained stably.
- Particularly when the pull tab is extended to the shoulder mouth of the slider body from the bridge portion of the pull tab attaching post, the pull tab is preferably attached such that the first face of the first pull tab main body portion faces downward (upper blade side). Consequently, when the slider is hidden on the back side of the seat cover, the male engaging elements of the first pull tab main body portion can be easily engaged with the seat cover back side, whereby the slider can be fixed at a predetermined position securely.

slider body 10 such that the shoulder mouths are separated by the guidingpost 13, and a rear mouth is formed at the rear end of theslider body 10. A Y-shaped element guide passage which brings the right and left shoulder mouths and the rear mouth into communication with each other is provided between the upper andlower blades elements 3 to pass therethrough when theslide fastener 7 described later is constructed. - The pull
tab attaching post 14 includes right andleft leg portions bridge portion 14 c. The right andleft leg portions upper blade 11 from a substantially central portion in the back-forth direction of the slider. Thebridge portion 14 c is stretched between top ends of the right andleft leg portions tab attaching post 14 is formed into a symmetrical shape. Thebridge portion 14 c is disposed in parallel to the top face of theupper blade 11, and one end of thepull tab 20 is attached to thebridge portion 14 c. In the present invention, the right andleft leg portions upper blade 11 as long as they are disposed apart from each other in a transverse direction of theslider body 10. The positions at which the right and left leg portions are erected can be changed easily corresponding to the width dimension or the like of thepull tab 20. - The
pull tab 20 is formed of a woven narrow thin belt-like body and bendable elastically. Thepull tab 20 is comprised of a first pull tabmain body portion 21 disposed in the back-forth direction of the slider as a grip portion, a second pull tabmain body portion 22 formed shorter in the back-forth direction than the first pull tabmain body portion 21, and afolding portion 23 which connects the first and second pull tabmain body portions - The first pull tab
main body 21 is formed relatively wide in the right-left direction in order for a user to be able to grip easily. The first pull tabmain body portion 21 has a plurality ofhooks 24 on one surface (first surface 21 a), thereby forming a surface fastener. - The second pull tab
main body portion 22 has the same width in the right-left direction as the first pull tabmain body portion 21. Further, the second pull tabmain body portion 22 has a plurality ofloops 25 on the surface on the same side as a face on which thehooks 24 of the first pull tabmain body portion 21 are disposed, thereby constructing a surface fastener which allows engagement/disengagement with/from thehooks 24 of the first pull tabmain body portion 21. - The folding
portion 23 is formed narrower than the first and second pull tabmain body portions hooks 24 orloops 25 may be disposed on both the front and rear surfaces thereof. - In the meantime, the pull tab of the present invention is not limited to this example, but the first and second pull tab
main body portions hooks 24 and theloops 25 mixedly on each first plane. - The
pull 20 of the first embodiment can be manufactured easily by punching out, for example, a surface fastener tape in which the hooks and the loops are disposed in parallel at predetermined intervals into a shape shown inFIG. 2 . The manufacturedpull tab 20 is installed on thebridge portion 14 c of theslider body 10 as follows. - First, the second pull tab
main body portion 22 of thepull tab 20 is inserted in between theupper blade 11 of theslider body 10 and thebridge portion 14 c of the pulltab attaching post 14, so as to align thefolding portion 23 of thepull tab 20 with a position of thebridge portion 14 c of the pulltab attaching post 14. Thereafter, the second pull tabmain body portion 22 is folded to the first pull tabmain body portion 21 side, and the first pull tabmain body portion 21 and the second pull tabmain body portion 22 are engaged with each other through thehooks 24 and theloops 25. Consequently, thepull tab 20 can be easily attached to thebridge portion 14 c of theslider body 10 such that thepull tab 20 is wound around thebridge portion 14 c. - In this case, as shown in
FIG. 3 , the first pull tabmain body portion 21 of thepull tab 20 is engaged with a partial area on thefolding portion 23 side on which the second pull tabmain body portion 22 is overlaid. Thus, in a portion on which no second pull tabmain body portion 22 is overlaid, thehooks 24 disposed on thefirst surface 21 a side are exposed. - In the first embodiment, the
pull tab 20 is installed rotatably around thebridge portion 14 c such that, in a state that thepull tab 20 is extended to the rear mouth side of theslider body 10 from thebridge portion 14 c of the pulltab attaching post 14, thefirst surface 21 a of the first pull tabmain body portion 21 faces upward, in other words, in a state that the pull tab is extended to the shoulder mouth side of theslider body 10 from thebridge portion 14 c of the pulltab attaching post 14, thefirst face 21 a of the first pull tabmain body portion 21 faces downward (to the upper blade 11). - The
slide fastener 7 is constructed by placing theslider 1 of the first embodiment on the right and leftelements 3 of the pair of right and leftfastener stringers 2 as shown inFIGS. 4 and 5 . In this case, the pair of right and leftfastener stringers 2 are sewed to opposing tape side edge portions of the right and leftfastener tapes 4 with acore thread 6 passed through the coil-likecontinuous elements 3. - In the
slide fastener 7 having theslider 1 of the first embodiment, thepull tab 20 of theslider 1 is formed of an elastically bendable belt-like body, and the pull tab folding portion 23 (post attaching portion) is attached rotatably in the sliding direction of theslider 1 around the pulltab attaching post 14 of theslider body 10. Thus, theslide fastener 7 of the first embodiment is excellent in operability of theslider 1 because thepull tab 20 of theslider 1 is easy to grip to allow theslider 1 to be operated smoothly. - Further, in the
slider 1 of the first embodiment, thepull tab 20 is attached directly to the pulltab attaching post 14 without use of any metal member. With this configuration, even if thepull tab 20 comes into contact with theslider body 10 made of a synthetic resin or other members, generation of contact sound can be prevented effectively, so that theslider fastener 7 from which no sound is produced can be constructed. - As shown in
FIGS. 6 and 7 , theslide fastener 7 of the first embodiment can be used preferably in a seat cover or the like of avehicle seat 31. In this case, thevehicle seat 31 has aseat cushion 32 and a seat back 33. Theseat cushion 32 and the seat back 33 include a seat frame (not shown), a pad (not shown) fixed to the seat frame and having cushion performance, and seat covers 34, 35 for covering the pad. - The
seat cover 35 for use in the seat back 33 has askin portion 35 a composed of synthetic leather disposed on the outer face side and asponge portion 35 b disposed on the inner side and having cushion performance. Two parallel cut-ins 36 are formed on the seat rear face side of theseat cover 35 in the up-down direction of the seat, and theslide fasteners 7 of the first embodiment are sewed along these cut-ins 36 (seeFIG. 7 ). - In this case, the
slide fastener 7 is disposed throughout the entire length of the cut-ins 36 of the seat cover rear face portion and is also extended so as to project by a predetermined length downward from a rear faceportion bottom edge 37 of theseat cover 35. Theslide fastener 7 is attached so that end stops are disposed at both top and bottom end portions of theelements 3. When theslider 1 is slid downward of theseat 31 along theelements 3, theslide fastener 7 is closed. - When the
slide fastener 7 of the first embodiment is used in theseat cover 35 of thevehicle seat 31, theseat cover 35 is applied to the seat back 33 such that eachslide fastener 7 is opened, and thereafter, theslider 1 is slid downward to close theslide fastener 7, so that theseat cover 35 can be attached easily to the seat back 33 with a good appearance. - Thereafter, an extending
portion 7 a of theslide fastener 7 extending from the rear faceportion bottom edge 37 of theseat cover 35 is folded to the back side (sponge portion 35 b) of the seat cover rear face portion as shown inFIG. 8 and then inserted in between theseat cover 35 and the pad. By doing so, the extendingportion 7 a can be hidden invisibly from the surface of theseat 31. - Particularly in the
slider 1 of the first embodiment, thehooks 24 are exposed from the portion on which no second pull tabmain body portion 22 is overlaid of thefirst surface 21 a of the first pull tabmain body portion 21 of thepull tab 20. Thus, when the extendingportion 7 a of theslide fastener 7 is hidden on the cover back side, thehooks 24 of the first pull tabmain body portion 21 are engaged with thesponge portion 35 b of theseat cover 35 so as to fix the position of theslider 1. Consequently, even if, for example, the vehicle vibrates during its traveling, it is possible to prevent deviation of the position of theslider 1 and dangling of theslider 1 between theseat cover 35 and the pad portion. - In addition to an effect of preventing generation of the contact sound between the
pull tab 20 and theslider body 10, etc., the position of theslider 1 is fixed to prevent theslider 1 from coming into contact with other members such as the seat frame of theseat 31. This blocks generation of the contact sound between theslider 1 and the seat frame, etc. - Further, because the position of the
slider 1 is fixed, the extendingportion 7 a of theslider fastener 7 hidden on the cover back side can be prevented from drooping from the rear faceportion bottom edge 37 of the seat cover due to vibration or the like of the vehicle so that the extendingportion 7 a is exposed. Consequently, a good appearance can be secured stably. - In the meantime, the
slide fastener 7 of the first embodiment can be applied to, for example, nursing care clothes, baby clothes and infant clothes as well as theseat cover 35 of thevehicle seat 31 from viewpoints of operability of theslider 1 and preventing generation of sound. Particularly theslide fastener 7 of the first embodiment, the position of theslider 1 can be fixed by thehooks 24 disposed on the pull tab of theslider 1. With this configuration, theslider 1 can be prevented from being operated by a child by a mistake effectively when the slide fastener is used in, for example, baby clothes or infant clothes. - Next, a slider for a slide fastener according to a second embodiment of the present invention will be described.
FIG. 9 is a side view schematically showing the slider for a slide fastener according to the second embodiment. In the second embodiment and third to fifth embodiments described later, like reference numerals are attached to components and member having the same structure as the first embodiment, and description thereof is omitted. - A
slider 41 of the second embodiment shown inFIG. 9 has aslider body 10 and apull tab 42. Theslider body 10 has the same configuration as the first embodiment. On the other hand, thepull tab 42 of the second embodiment is formed of a woven narrow thin belt-like body. Thepull tab 42 has first and second pull tabmain body portions folding portion 45 for connecting the pull tabmain body portions - The first and second pull tab
main body portions main body portions portion 45 is formed narrower than the first and second pull tabmain body portions - The
pull tab 42 of the second embodiment is attached to thebridge portion 14 c of theslider body 10 in the following manner. The second pull tabmain body portion 44 is inserted in between theupper blade 11 of theslider body 10 and the pulltab attaching post 14 so as to align thefolding portion 45 of thepull tab 42 with a position of the pulltab attaching post 14. Further, the second pull tabmain body portion 44 is folded to the first pull tabmain body portion 43 side to be overlaid on the first pull tabmain body portion 43. Thereafter, the first pull tabmain body portion 43 and the second pull tabmain body portion 44 are sewed together. - In the slide fastener constructed using the
slider 41 of the second embodiment, thepull tab 42 is constituted of an elastically bendable belt-like body and attached such that the pulltab folding portion 45 can rotate in a sliding direction of theslider 41 around the pulltab attaching post 14 of theslider body 10. Thus, the slide fastener of the second embodiment allows thepull tab 42 of theslider 41 to be griped easily and theslider 41 to be operated smoothly. - In the
slider 41 of the second embodiment, thepull tab 42 is attached directly to the pulltab attaching post 14 without use of any metallic member. Accordingly, even if thepull tab 42 comes into contact with the slider body made of a synthetic resin or other members such as a sheet frame, generation of its contact sound can be prevented effectively so as to construct a slide fastener from which any sound is not produced. - The slide fastener of the second embodiment can be used in the
seat cover 35 of thevehicle seat 31 like the first embodiment and additionally, may be applied preferably to, for example, nursing care clothes, baby clothes and infant clothes from viewpoints of operability of the slider, prevention of any sound, and excellent tactile feeling. - Subsequently, a slider for a slide fastener according to a third embodiment of the present invention will be described.
FIG. 10 is a side view schematically showing the slider for a slide fastener of the third embodiment. - A
slider 46 shown inFIG. 10 includes aslider body 10′ and apull tab 47. In thisslider body 10′, the shape of a pulltab attaching post 14′ is changed with respect to theslider body 10 of the first and second embodiments; abridge portion 14 c′ stretched between right andleft leg portions 14 a′ and 14 b′ is formed cylindrically; and a pull tab insertion slit is provided in a substantially central portion of thebridge portion 14 c′. In the meantime, other configuration than the pulltab attaching post 14′ of theslider body 10′ is the same as theslider body 10 of the first and second embodiments. - The
pull tab 47 is formed by molding a synthetic resin. Thepull tab 47 includes a pull tabmain body portion 48 disposed in the back-forth direction of the slider and apost attaching portion 49 formed at one end of the pull tabmain body portion 48. A plurality ofhooks 50 are formed on afirst face 48 a on one side of the pull tabmain body portion 48. - In this case, the pull tab
main body portion 48 is formed of a hard synthetic resin such that its width in the right-left direction is relatively large for a user to grip easily. Thepost attaching portion 49 is formed integrally with the pull tabmain body portion 48 and has a donut-like circular section which allows itself to rotate around thebridge portion 14 c′ of theslider body 10′. - When attaching the
pull tab 47 to theslider body 10′, thepost attaching portion 49 of thepull tab 47 is obliquely inserted into the slit provided on thebridge portion 14 c of theslider body 10, so that thebridge portion 14 c′ is inserted into a hollow portion of thepost attaching portion 49. Further, by rotating thepull tab 47 while moving it in the width direction of theslider body 10′, thebridge portion 14 c′ is fitted to the hollow portion in thepost attaching portion 49 from both the right and left sides. By doing so, thepull tab 47 is rotatably attached to theslider body 10′. - The method of attaching the
pull tab 47 to theslider body 10′ is not limited to any particular one. For example, thepull tab 47 is constructed separately of a first member in which a portion having a C-shaped section constituting part of thepost attaching portion 49 and the pull tabmain body portion 48 are formed integrally, and a second member having a circular section constituting the remaining portion of thepost attaching portion 49. Then, both end faces of the second member are fitted to both the end faces of the C-shaped portion with thebridge portion 14 c′ of theslider body 10 inserted into the C-shaped portion of the first member. Subsequently, the first member and the second member are fused together or bonded together through their contact portions, so as to achieve attachment of thepull tab 47 to theslider body 10. - Because the
pull tab 47 made of a synthetic resin is attached directly to the pulltab attaching post 14′, theslider 46 obtained in this way can suppress generation of any contact sound when thepull tab 47 comes into contact with the slider body made of a synthetic resin. - The slide fastener constructed with this
slider 46 may be used preferably in theseat cover 35 of thevehicle seat 31 like the first embodiment. Theslide fastener 46 of the third embodiment may be used in theseat cover 35 of thevehicle seat 31. In this case, when the extending portion from theseat cover 35 of the slide fastener is hidden on the cover back side like the first embodiment, thehooks 50 of the pull tabmain body portion 48 can be engaged easily with thesponge portion 35 b of theseat cover 35. This is because thefirst face 48 a of the pull tabmain body portion 48 has a plurality ofhooks 50. - Consequently, substantially the same effect as the first embodiment can be obtained, for example, deviation of the position of the
slider 46 or dangling of theslider 46 can be prevented even if, for example, the vehicle is vibrated during its traveling. - A slider for a slide fastener according to a fourth embodiment of the present invention will be described. Here,
FIG. 11 is a perspective view showing a slider body of the slider andFIG. 12 is a longitudinal sectional view showing a section of the slider. - The
slider 51 of the fourth embodiment includes aslider body 52 and apull tab 20. Theslider body 52 includes upper andlower blades post 13 which connects the front end portions of the upper andlower blades tab attaching post 53 formed integrally on the top face of theupper blade 11, and right and leftflanges 15 disposed on both the right and left side edges of thelower blade 12. - The pull
tab attaching post 53 includes right andleft leg portions upper blade 11, abridge portion 53 c which is stretched between the top end portions of the right andleft leg portions tongue piece 53 d projected forward in parallel to the top face of theupper blade 11 from thebridge portion 53 c. - The
pull tab 20 of the fourth embodiment is the same as the first embodiment, and includes first and second pull tabmain body portions folding portion 23 for connecting the first and second pull tabmain body portions main body portion 21 of the pull tab has a plurality ofhooks 24 on afirst surface 21 a thereof. The second pull tabmain body portion 22 has a plurality ofloops 25 capable of engaging thehooks 24 of the first pull tabmain body portion 21 on afirst surface 22 a thereof. - This
pull tab 20 is attached such that it is wound around thebridge portion 53 c and thetongue piece 53 d of the pulltab attaching post 53 by inserting the second pull tabmain body portion 22 between theupper blade 11 of theslider body 52, thebridge portion 53 and thetongue piece 53 d of the pulltab attaching post 53, and then folding back the second pull tabmain body portion 22 to the first pull tabmain body portion 21 side to engage thehooks 24 with theloops 25. - Particularly in the fourth embodiment, the
pull tab 20 is attached such that the extending direction of thepull tab 20 from the pulltab attaching post 53 is oriented forward of the slider. Consequently, the extending direction of thepull tab 20 is limited to the forward direction by thetongue piece 53 d of the pulltab attaching post 53, and thepull tab 20 is blocked from rotating around thebridge portion 53 c and thetongue piece 53 d. This enables thepull tab 20 to be blocked from dangling freely. - In the slide fastener constructed with the
slider 51 of the fourth embodiment, thepull tab 20 of theslider 51 is bendable elastically. With this configuration, thepull tab 20 can be bent easily by gripping with the fingers when theslider 51 is operated, although thepull tab 20 cannot be rotated around the pulltab attaching post 53. - For example, when the slide fastener is closed, the
slider 51 can be slid easily in its closing direction by gripping thepull tab 20 of theslider 51 and pulling it in an extension direction of thepull tab 20. Further, when the slide fastener is opened to the right and left sides, theslider 51 can be slid easily in its opening direction by gripping thepull tab 20 of theslider 51 and pulling it in an opposite direction (backward) to the extending direction while bending it (see two-dot and dash line inFIG. 12 ). When the fingers are released from thepull tab 20 after theslider 51 is operated, thepull tab 20 can be reoriented forward of the slider with respect to thebridge portion 53 c by thetongue piece 53 d provided on the pulltab attaching post 53 and the elastic restoration of thepull tab 20. - In case where the slide fastener of the fourth embodiment is used in the
seat cover 35 of thevehicle seat 31 shown inFIG. 6 , thepull tab 20 can be oriented forward of the slider securely with respect to thebridge portion 53 c when the slide fastener is closed to cause the extending portion of the slide fastener to be hidden by the back side of the seat cover rear face portion. Thus, thehooks 24 exposed on thefirst face 21 a of the first pull tabmain body portion 21 of thepull tab 20 can be securely engaged with thesponge portion 35 b of theseat cover 35, and the position of the slider can be fixed more securely than the first embodiment. In the meantime, thetongue piece 53 d may be projected backward in parallel to the top face of theupper blade 11 from thebridge portion 53 c. - A slider for a slide fastener according to a fifth embodiment of the present invention will be described.
FIG. 13 is a longitudinal sectional view showing the section of the slider. - A
slider 61 of the fifth embodiment includes aslider body 62 and apull tab 20. Theslider body 62 includes upper andlower blades post 13 which connects the front end portions of the upper andlower blades tab attaching post 63 formed integrally on the top face of theupper blade 11, and right and leftflanges 15 disposed on both the right and left side edges of thelower blade 12. - The pull
tab attaching post 63 includes right and left leg portions erected upward from both right and left side edge portions of theupper blade 11 and abridge portion 63 c which is stretched between the top end portions of the right and left leg portions. Thebridge portion 63 c is formed in a larger thickness than theslider 1 of the first embodiment. - On the other hand, the
pull tab 20 of the fifth embodiment is the same as the first and fourth embodiments and includes first and second pull tabmain body portions folding portion 23. - The
pull tab 20 of the fifth embodiment is wound around thebridge portion 63 c by inserting the second pull tabmain body portion 22 in between theupper blade 11 of theslider body 62 and thebridge portion 63 c and folding the second pull tabmain body portion 22 to the first pull tabmain body portion 21 side so that the second pull tabmain body portion 22 is engaged with the first pull tabmain body portion 21. Thereafter, with thepull tab 20 held such that it is extended forward of the slider from thebridge portion 63 c, the foldingportion 23 of thepull tab 20 is fixed to thebridge portion 63 c by ultrasonic welding or the like. - Consequently, the extending direction of the
pull tab 20 is limited to forward and thefolding portion 23 of thepull tab 20 is blocked from rotating around thebridge portion 63 c. Thus, thepull tab 20 can be prevented from dangling freely around the pulltab attaching post 63. - In the slide fastener constructed with the
slider 61 of the fifth embodiment, thepull tab 20 of theslider 61 is bendable elastically. Thus, in the slide fastener of the fifth embodiment, thepull tab 20 can be bent by gripping with the fingers when operating theslider 61 like the fourth embodiment, and when the slide fastener is closed or opened, the sliding operation of theslider 61 can be carried out easily. Further, when the fingers are released from thepull tab 20 after theslider 61 is operated, thepull tab 20 can be oriented forward of the slider with respect to thebridge portion 63 c, thereby obtaining the same effect as the slide fastener of the fourth embodiment.
