Description

zipper

The present invention relates to a zipper capable of reversing a direction in which a first slider and a second slider are opposed to each other with respect to a meshing opening of the fastener stringer, and particularly relates to a latch capable of easily and The zipper of the first slider and the second slider is smoothly inserted.

In order to open and close the left and right front body pieces of the clothes, a zipper with a detachable insert or a zipper that can be reversed is attached to the opening portion of the clothes, etc., at the lower end of the element row. For example, the zipper that can be reversed is generally that the two sliding members are mounted on the element row in a direction in which the engaging openings are opposed to each other, and that the two rows of the sprocket are opened from the longitudinal direction by using the two sliding members. The way is formed.

In the zipper capable of being reversed, one end (rear end portion) of one of the pair of left and right zip fastener tapes is provided with a pin in a manner continuous with the element rows, and the other zipper chain One end (rear end) is provided with a pin in a manner continuous with the chain of teeth. Here, the slider that is disposed apart from the tubular pin among the two sliders is defined as the first slider, and is placed closer to the tubular pin than the first slider and abuts against the stopper of the tubular pin. The stopped slider is defined as the second slider.

In such a zipper that can be reversed, when the sprocket chain is engaged and the zipper is closed in a state in which the left and right zipper tapes are separated from each other, the following operation must be performed, that is, the second slider is abutted on one. a pin of the zipper tape, and the first slider abuts against the second slider and maintains the two sliders in contact with each other, and thereafter, the latch provided to the other zipper tape is from the first slider The guide port is inserted and sufficiently inserted into a specific position so that the first slider and the second slider are inserted. Thereafter, by sliding (pulling up) the first slider in a direction away from the second slider, the left and right fastener elements arranged on the slide fastener can be sequentially engaged.

However, when the zipper that can be reversed as described above is used for clothing or the like, there is a case where the user does not visually check the first slider, the second slider, or the latch to perform the above operation. . As a result, for example, when the second slider is not properly brought into contact with the first slider stopped by the pin (the state in which the first slider and the second slider are separated), the latch is inserted, and Alternatively, the first slider may be pulled up in a state where the second slider is in contact with the first slider but the latch is not sufficiently inserted into the specific position.

However, in the above state, the latch is not held at a specific position with respect to the first slider and the second slider, and therefore the first slider cannot be slid in the meshing direction of the element rows. As a result, the user is annoyed with the operation of the zipper. Further, among the users, the first slider is forcibly slid in a state where the latch is not sufficiently inserted, and the zipper is broken. Therefore, in the zipper that can be reversed, it is required to improve the operability such that the plug is easily inserted into the first slider and the second slider, and the sliding of the first slider is easily started.

In the above, a technique for improving the operability of a zipper that can be reversed is described in Japanese Patent Publication No. Sho 54-18325 (Patent Document 1) or International Publication No. 2010/070743 (Patent Document 2).

In the above-described Patent Document 1, a zipper is disclosed in which the second slider and the first slider can be formed by forming the slit groove and the sheet portion which can be fitted to each other in the first slider and the second slider. The positioning of the two sliders is performed when moving to the pin side end of the element row.

Specifically, as shown in FIGS. 30 and 31, the zipper 100 that can be reversed as described in Patent Document 1 has a left and right fastener chain belt 101 having a chain of teeth, and a pin 102 having a zipper on the left side. The lower end portion of the belt 101 is disposed in a continuous manner from the chain gear row; the tubular pin 103 is disposed at a lower end portion of the right side fastener string belt 101 in a continuous manner from the element tooth row; and the first slider 104 and the second slider 105, which is slidably mounted to the left and right chain rows. In this case, the second slider 105 is disposed closer to the side of the plug 102 and the pin 103 than the first slider 104.

In the zipper 100 of Patent Document 1, the inner surface of the upper blade and the lower blade of the first slider 104 is provided with a slit groove 104a toward the inner side from the end edge of the engagement port side. Further, in the second slider 105, the upper blade and the lower blade are extended from the end edge of the upper blade and the lower blade toward the first slider 104 so as to be engageable in the first slider. The sheet portion 105a of the slit groove 104a of 104.

According to the zipper 100 of the patent document 1 configured in this manner, after the second slider 105 and the first slider 104 are sequentially moved to the end portion of the element pin row 103, the pin 102 is inserted into the first slide. In the case of the member 104 and the second slider 105, the sheet portion 105a formed in the second slider 105 is fitted into the slit groove 104a formed in the first slider 104. As a result, the engagement posture between the first slider 104 and the second slider 105 is in a state of being unstable in the thickness direction (height direction) and the width direction of the slide fastener 100.

In the zipper 100 of the patent document 1, the first slider after the insertion of the latch 102 can be performed by the simple structure of the slit groove 104a of the first slider 104 and the sheet portion 105a of the second slider 105 as described above. The position of the first slider 104 and the second slider 105 can be stabilized by the relative positioning of the first slider 104 and the second slider 105. Therefore, when the first slider 104 is pulled in the meshing direction of the element rows (the direction away from the first slider 104) in order to mesh the right and left fastener elements, the sliding of the first slider 104 can be smoothly performed. The ground starts, so that the operability of the zipper 100 that can be reversed can be improved.

On the other hand, in the slide fastener described in the above-mentioned Patent Document 2, the following fastening structure is provided, that is, the first tab of the first slider that is disposed apart from the tubular pin and the biasing pin can be disposed. The second pull-tab of the second slider is engaged with the pull-tabs so as to overlap each other, and the first slider and the second slider are held in a state in which the engaging openings are opposed to each other when the tabs are engaged with each other.

According to the zipper of Patent Document 2, the first slider and the second slider can be stably held in a state in which the engaging openings face each other, and the first slider and the second slider can be easily opposed. The position is aligned. Therefore, when the pin is inserted into the first slider and the second slider, the positional displacement between the first slider and the second slider is less likely to occur, and the two sliders can be prevented from being separated from each other.

Thereby, the plug can be easily inserted into a specific position, and therefore the sliding of the first slider can be easily started smoothly after the insertion of the plug. Further, when the latch is pulled out from the first slider and the second slider, the first slider and the second slider can be stably held in contact with each other, so that the latch can be smoothly pulled out. .

[The problem that the invention wants to solve]

In the zipper 100 that can be reversed as described in the above-described Patent Document 1, the sheet portion 105a provided in the second slider 105 is fitted into the slit groove 104a of the first slider 104 as described above. The relative positions of the first slider 104 and the second slider 105 are aligned.

However, in the case of the zipper 100 of Patent Document 1, the second slider 105 and the first slider 104 are moved to the end portion of the sprocket row 103 by the user, and the second slider may not be able to be used. The sheet portion 105a of the 105 is fitted into the slit groove 104a of the first slider 104. When the sheet portion 105a of the second slider 105 is not fitted into the slit groove 104a of the first slider 104, the position or posture of the second slider 105 is difficult to stabilize.

Therefore, when the first slider 104, the second slider 105, and the latch 102 are not visually recognized, the relative displacement of the first slider 104 and the second slider 105 may be caused. There is a case where the position of the first slider 104 and the second slider 105 is shifted, and the plug 102 cannot be stably inserted into a specific position.

Further, in Patent Document 1, when the sheet portion 105a of the second slider 105 is fitted into the slit groove 104a of the first slider 104 before the plug 102 is inserted into the second slider 105, the first The slider 104 and the second slider 105 are arranged in a straight state in which the first center line located at the center in the width direction of the first slider 104 and the second center line located at the center in the width direction of the second slider 105 are linearly arranged. be kept.

When the first slider 104 and the second slider 105 are held in a straight state, the introduction port of the first slider 104 which is the insertion port of the plug 102 faces the longitudinal direction of the fastener string 101. be kept. Therefore, when the plug 102 is inserted from the introduction port of the first slider 104, the plug 102 is not straightly moved as long as the length of the fastener string 101, and is oriented from the front of the second slider 105. When the introduction port of the slider 105 is operated to move straight, the plug 102 is likely to be hooked to the pin 103 or the like, and the plug 102 cannot be sufficiently inserted into a specific position. Therefore, the insertion operation of the plug 102 which is performed while the first slider 104 and the second slider 105 are held straight as described above may be annoying.

On the other hand, in the zipper that can be reversed as described in Patent Document 2, by laminating the first tab of the first slider and the second tab of the second slider, the two tabs can be The snap-fit structure is simply engaged, whereby the first slider and the second slider can be stably held in a state where the meshing ports face each other.

Therefore, in Patent Document 2, even if the first slider and the second slider are not visually recognized each time, the first slider and the second slider can be prevented from being separated, and the first slider and the second slider can be prevented. The insertion operation of the latch is stably performed in the state of contact.

However, in the zipper of Patent Document 2, when the first pull tab of the first slider and the second pull tab of the second slider are engaged by the snap-fit structure, the first slider is the first one. The first slider and the second slider are held in a straight state so that the center line and the second center line of the second slider are arranged linearly. Therefore, in the zipper of Patent Document 2, as in the case of Patent Document 1, there is a case where the operation of the plug is annoying, and it is desirable to insert the plug more easily and smoothly into a specific position.

The present invention has been made in view of the above problems, and a specific object thereof is to provide a zipper excellent in operability of a plug, which is a zipper that can be reversely opened, and can be stably and appropriately performed when the left and right element rows are engaged.

And the pull tab is held by the slider main body; and the pull tab of the first slider has an insertion hole portion into which the engagement protruding portion of the second slider can be inserted. [Effects of the Invention]

The zipper of the present invention is formed as a zipper that can be reversely opened, and includes: a pair of left and right first zipper tapes and a second zipper tape; and a tubular pin that is continuous from one end of the first zipper tape The latch is disposed at one end of the second zipper tape so as to be continuous from the element row; and the first slider and the second slider are disposed at least in a second manner so as not to fall off The sprocket rows of the zipper tapes are disposed with the end sides of the engaging opening sides facing each other. In this case, the first slider and the second slider are respectively disposed in a slider that is disposed at a position away from the cylinder pin and a slider that is disposed at a position offset from the cylinder pin.

In the slide fastener of the present invention, the first slider and the second slider have a posture maintaining structure in which the end portion of the first slider abuts (connects) the second slider. Then, the first slider can be temporarily fixed (held) in the inclined posture with respect to the second slider.

Here, the inclined posture of the first slider refers to the first center line located at the center in the width direction of the first slider with respect to the second center located at the center in the width direction of the second slider when the zipper is viewed from above. The line is preliminarily set to a posture inclined at a specific angle of the insertion operation of the pin. In this case, the specific inclination angle of the first center line inclined with respect to the second center line is set according to the shape of the first slider and the second slider, and the like.

The zipper of the present invention having the posture maintaining structure as described above according to the first slider and the second slider, when the zipper in a state in which the left and right fastener stringers are separated from each other is closed, the first slider is brought into contact with each other. When the second slider is abutted against the stopper of the latch, the tilting posture of the first slider relative to the second slider at an obliquely fixed angle can be used instead of the above-described patent by the posture maintaining structure. The posture of the straight state in the literature 1 or the patent document 2 is simply and stably maintained.

In particular, in the posture maintaining structure of the present invention, the first slider can be held such that the end portion of the first slider is directed toward the side opposite to the fastener string on which the pin is disposed (the zipper is provided with the pin). The tilting posture of the chain belt side is inclined, whereby the introduction port of the first slider into which the plug is inserted can be inclined toward the side opposite to the cylinder pin, so that the insertion operation of the plug can be easily performed.

Thereafter, by inserting the latch from the introduction port of the first slider, the first slider and the second slider are appropriately held in a positional relationship in which the posture is held by the posture maintaining structure, and therefore the user does not visually When the first slider, the second slider, and the latch are operated, it is possible to prevent the positional displacement of the first slider or the second slider, the separation between the first slider and the second slider, and the posture of the first slider. The inclination posture is arbitrarily inclined from the above.

Therefore, in the slide fastener of the present invention, the insertion pin can be easily inserted from the introduction port of the first slider, and the plug can be smoothly and stably inserted into the specific positions of the first slider and the second slider. Thereby, the sliding of the first slider can be smoothly started to mesh the left and right element rows.

In particular, in the present invention, the first slider is not in the straight posture as in the above-described Patent Document 1 or Patent Document 2, but the posture maintaining structure is used to facilitate the insertion operation of the plug. The specific tilt posture as described above is maintained. Therefore, in the present invention, the insertion operation of the plug can be performed in a direction inclined from the longitudinal direction of the fastener stringer as compared with the above-described Patent Document 1 or Patent Document 2. Therefore, the operability of the latch in the zipper that can be reversed can be greatly improved.

In the slide fastener of the present invention, one of the first slider and the second slider has an engagement portion, and the other of the first slider and the second slider has a card that can be engaged with the engagement portion. Joint department. Thereby, by engaging the engaging portion provided in one slider with the engaged portion provided in the other slider, the first slider can be more stably and appropriately held as a specific plug that can be easily inserted. The tilting position makes it easier to insert the latch.

In the slide fastener of the present invention, at least one of the engagement port side end portion of the first slider and the engagement port side end portion of the second slider has an inclined portion that is inclined with respect to the slider width direction in plan view. In addition, the inclined portion is formed such that at least one of the right and left outer side edge portions of the engagement port side end portion is disposed in the longitudinal direction at the center portion in the width direction of the engagement end side end portion. With this configuration, when the first slider and the second slider are held by the posture maintaining structure, the first slider can be stably held in a specific tilt posture. Therefore, the insertion of the latch can be performed more easily and smoothly.

Further, the posture holding structure of the present invention is formed by inserting the latch from the introduction port of the first slider and inserting it into the first slider and the second slider, thereby enabling the first slider to be rotated and releasing the tilt posture. Keep it. With this configuration, even if the first slider is held in the specific tilt posture as described above by the posture maintaining structure, the first slider can be rotated when the latch is inserted into the first slider and the second slider. The first center line of the first slider and the second center line of the second slider are arranged linearly with respect to the second slider so as to be in a straight state. As a result, the sliding of the first slider can be started more smoothly toward the meshing direction of the element rows.

Further, in the present invention, one of the first slider and the second slider (for example, the first slider) has a width from the slider toward the other slider (for example, the second slider) The extension is used as a posture maintaining structure. Further, the posture maintaining structure is formed to hold the first slider in an inclined posture by bringing the extending portion of one slider into contact with the other slider.

Here, the extension of the extension toward the other slider refers to the length direction of the slider, and the extension is based on the position of the edge of the engagement opening on the upper and lower flaps of the slider. The position beyond the end edge of the engagement opening extends (projects) toward the other slider. For example, the extension portion of the present invention may be formed from the end of the engaging opening side of the sliding member toward the other sliding member, or may be provided from the side portion of the lower sliding member of the sliding member. At least one of the side portions of the lower flange portion of the lower blade extends and passes over the engagement port side end edge of the lower blade toward the other slider. By using the posture holding structure having such an extension portion, the first slider can be more stably held (fixed) in a specific tilt posture when the first slider abuts against the second slider.

In particular, in the slide fastener of the present invention, the first slider and the second slider have a slider body formed by connecting the end of the inlet port side of the upper blade to the end of the inlet port of the lower blade by a connecting post. Further, one of the first slider and the second slider forms a thickness of the upper or lower flap larger than the other slider, and has a meshing end side from the upper or lower flap At least one extension extending toward the other slider. Further, the other of the first slider and the second slider has a surface (upper surface) protruding from the upper blade or an outer surface (lower surface) of the lower blade, and is capable of contacting the extension portion And the snap-in protrusion is engaged. In this case, the posture maintaining structure is formed by the extending portion disposed on one of the sliders and the engaged protruding portion disposed on the other slider, and is formed by the extending portion in the posture maintaining structure. The side surface portion (for example, the inner side surface portion) is in contact with and engaged with the engaged projection portion to hold the first slider and the second slider in contact with each other, and holds the second slider in an inclined posture. Therefore, when the first slider is brought into contact with the second slider, the first slider can be stably and appropriately held in a specific tilt posture in which the plug is easily inserted, and the insertion operation of the latch can be more easily performed.

In this case, the extension portion disposed on the slider has a base end portion extending from the outer side edge portion of the engagement port side end portion toward a slider; and a hook portion from the end portion of the base end portion The portion is bent or bent toward the central portion in the width direction. Further, the extension portion is formed so as to be able to pass over the engagement projection portion of the other slider when the engagement end side end portion of the first slider abuts against the second slider. Further, the extension portion and the engagement projection portion that form the posture holding structure have the inner peripheral side surface of the base end portion in the state in which the engagement end side end portion of the first slider abuts against the second slider, and the engaged side portion The first contact portion where the protruding portion contacts, and the second contact portion where the inner peripheral side surface of the hook portion contacts the engaged protruding portion.

Thereby, when the first slider is brought into contact with the second slider, the extension of one slider can be easily engaged with the engagement projection of the other slider. Further, since the extended portion of the posture holding structure is in contact with the engaged protruding portion at two different positions of the first contact portion and the second contact portion, the first slider can be stably held in a specific state. In the inclined posture, the state in which the first slider and the second slider are in contact with each other can be stably maintained. Therefore, the insertion operation of the latch can be performed more smoothly and more stably.

Further, the engaged projection portion of the posture holding structure has an inclined surface that is inclined downward toward the engagement port side end portion of the other slider. Therefore, when the first slider abuts against the second slider, the extension of the slider can smoothly pass over the engaged projection of the other slider, and is stably engaged with the engaged Highlights.

Further, the slide fastener of the present invention is formed such that when the latch is inserted from the introduction port of the first slider and inserted into the first slider and the second slider, the first slider is rotated from the tilt posture. On the other hand, the posture in which the first center line and the second center line are arranged linearly is maintained. Further, when the first slider is rotated from the tilting posture, the protruding portion of one slider and the protruding projection portion of the other slider are disposed differently from each other in the slider width direction. position. Therefore, when the first slider is slid after the plug is inserted into the first slider and the second slider, the extension of the posture holding structure and the engagement projection can be prevented from interfering with each other. The meshing direction of the tooth row smoothly starts the sliding of the first slider.

Further, the zipper of the present invention may be formed in such a manner that the second slider has an inlet-side end portion of the upper blade and an inlet-side end of the lower blade formed by a connecting post and is formed on the upper blade. A slider main body is protruded from the upper surface, and the first slider has a slider main body that is attached to the inlet end side end portion of the flap and the inlet end side end portion of the lower flap The connecting post is coupled to each other; and the pull tab is held by the slider main body and includes an insertion hole portion into which the engaging projection of the second slider can be inserted.

In other words, the posture holding structure in the slide fastener of the present invention may be formed by the insertion hole portion provided in the pull tab of the first slider and the engagement projection portion provided in the slider main body of the second slider. In the posture maintaining structure, the first slider can be brought into contact with the second slider, and the engaged projection of the second slider can be inserted into the insertion hole of the first slider. The first slider is simply and stably held in the above-described inclined posture at an obliquely fixed angle with respect to the second slider. Further, it is possible to stably maintain the state in which the first slider and the second slider are in contact with each other and connected. Thereby, the insertion operation of the latch can be easily performed, and the plug can be smoothly and stably inserted into a specific position of the first slider and the second slider.
