Description

Body and slide of slide for slide fastener

The present invention relates to a slide body of a slide fastener and a slide piece using the same. In detail, the present invention relates to a slide body and a slide piece with an automatic stop function.

As an example of a conventional slider with an automatic stop function, there are three parts including a main body, a pull tab that operates the main body, and a cover that is rotatably attached to the main body (Patent Document 1). The cover includes: an upper wall extending in the front-rear direction; and a side wall extending downward from a side end of the upper wall. In addition to the upper wall and the side wall, the cover also includes: an elastic piece as a leaf spring extending downward from the front end of the upper wall; and a stopper as a control claw extending downward from the lower end of the side wall and Control the body to be movable and immovable. The main body includes: an upper wing plate and a lower wing plate, which cover the upper and lower sprocket paths penetrating in the front-rear direction; and a front mounting post and a rear mounting post, which protrude from the upper surface of the upper wing plate in front and rear. And install the cover. Further, a claw hole communicating with the sprocket path is formed in the upper wing plate. The control claw is housed in the claw hole, and the head of the control claw collides with the sprocket by the return force of the leaf spring, whereby the slider becomes an immovable state, a so-called automatic stop state. The operation of operating the slider of the slide disclosed in Patent Document 1 is a pull-tab, and the control claws are raised toward the rear side in conjunction with the lifting operation. In addition, the operation of installing the cover body on the body is also the operation of installing the control claw on the body. The control claw and the cover body move in a different direction from the operation of the operation of the slider of the slider. In detail, the control claw and The cover faces downward with one side facing backward. In any of the above operations, the claw holes must not collide with the control claw to prevent the control claw from moving. In addition, in any operation, the control claws are displaced rearwardly. Therefore, in the automatic stop state, the claw holes are in a state where there is a gap between the control claws on the front and back sides. In addition, as an example of a conventional slider having an automatic stop function, there is a plate including a main body, a pull tab, a claw lever as a control claw, and a resilient force that causes a part of the claw lever to protrude into the body by elastic deformation. A spring and five parts that cover a pull tab, a leaf spring, and a claw lever, and attach the pull tab and the claw lever to a cover of the body (Patent Document 2). This system has the same function as the main body of Patent Document 1, and includes an upper wing plate, a lower wing plate, a front mounting post, and a rear mounting post. In addition to the claw hole, the upper wing plate also includes a locking base serving as a receiving recessed portion for receiving the front end of the claw lever. The operation of operating the slider of the slider disclosed in Patent Document 2 is the same as that of the slider disclosed in Patent Document 1. In addition, the operation of attaching the control claw to the main body is to move the control claw downward from directly above the main body, insert the front end of the claw lever into the receiving recess, and insert the rear end (claw) of the control claw into the claw hole. . In any of the above operations, the claw holes must not collide with the control claw to prevent the control claw from moving. In addition, during the operation of mounting the control claw on the main body, the control claw will not be displaced in the front-rear direction. Therefore, in the automatic stop state, the claw hole has a state with a gap behind the control claw.

[Problems to be Solved by the Invention] In addition, the number of parts is smaller than that of the five parts of the sliding part. On the other hand, the thickness of the control claw can be set regardless of the thickness of the cover compared with the slider of 5 parts compared with the slider of 3 parts. Therefore, when the applicant of the present invention applied for the present invention, he tried to integrate the leaf spring of the five parts with the cover in a manner that has the advantages of both the sliding parts of the five parts and the sliding parts of the three parts, that is, Attempts were made to make a sliding part of 4 parts. More specifically, the four-piece slider refers to a cover provided with a body, a pull tab, a control claw, and a plate spring. The sliding parts of 4 parts have almost the same structure as the sliding parts of 3 parts, so as long as the body can be common, by producing 1 type of body, 4 pieces of sliding parts and 3 parts can be produced. In other words, two types of sliding parts can be produced, which is ideal. In addition, when the slider of 4 parts and the slider of 3 parts make the body common, the length of the claw hole must be considered. The reason is that the case where the control claw is a separate part and the case where the control claw becomes a part of the cover are different in whether the claw hole has a gap in front of the control claw in the automatic stop state. In summary, it can be considered as follows. In other words, the sliding parts of the four parts are sliding parts of different types of the control claw and the cover body. In other words, the three-piece slide is a slide in which the control claw is a part of the cover. Therefore, an object of the present invention is to provide a slide body capable of controlling a type in which the claw is a part of a cover body, and a slide body of a type in which the control claw and the cover body are individual parts, and to provide a slide using the body. Pieces. [Technical means to solve the problem] The body of the slider for a slide fastener according to the present invention includes an upper wing plate and a lower wing plate, which cover the upper and lower sprocket paths penetrating in the front-rear direction, and a pillar, which connects the upper wing plate and the lower wing The upper and lower plates are connected to each other; the front mounting post and the rear mounting post, which protrude from the upper surface of the upper wing plate, and install a cover body; and a receiving recess, which can be connected to the front end of the control claw as a separate part of the cover Contained between the front mounting post and the rear mounting post in the upper surface of the upper wing plate. In addition, the front mounting post and the rear mounting post are provided on the side thereof with a front support portion and a rear support portion that support the cover body to swing up and down. In addition, the upper wing plate is provided with a claw hole between the mounting post and the receiving recess after the upper wing plate is in the upper surface. The claw hole can receive the claw portion of the control claw which is an individual part or integrated with the cover body, and is connected with the chain Tooth path is connected. The claw hole includes a first claw hole portion and a second claw hole portion. In addition, the first claw hole portion and the second claw hole portion are adjacent to each other in the width direction of the upper wing plate, and have different lengths in the front-rear direction. Specific examples of the first claw hole portion and the second claw hole portion include the following examples 1) and 2). 1) The upper wing is provided with a partition portion that separates the first claw hole portion and the second claw hole portion in the width direction, and the first claw hole portion and the second claw hole portion are separated by a partition portion. open. 2) The first claw hole portion and the second claw hole portion are continuous in the width direction. Regarding the length in the front-rear direction, regardless of the relationship between the first claw hole portion and the second claw hole portion. However, reducing the area of the holes is more desirable in terms of increasing the strength of the upper wing. In addition, when the claw portion of the control claw that is a separate component from the cover body protrudes into the sprocket path, the mounted portion formed on the upper side of the control claw with respect to the claw portion is placed on the upper wing plate. In addition, in order to increase the strength of the upper wing plate and stabilize the posture of the control claw, it is preferable to be configured as follows. That is, regarding the length in the front-rear direction, the first claw hole portion is shorter than the second claw hole portion. In addition, the upper wing is provided with a mounting portion that mounts a control portion of the control claw on a portion to be mounted on the upper side with respect to the claw portion. In addition, the placing portion is formed by being recessed downward in a stepwise manner from a portion excluding the claw hole, and is adjacent to the front side or the rear side with respect to the first claw hole portion. The first claw hole portion and the second claw hole portion may be configured as follows regardless of whether or not the positions of the front surfaces are aligned with each other. That is, the first claw hole portion and the second claw hole portion are different from each other in front and rear positions. As examples of the specific configuration of the slider using the above body, the following examples 1) and 2) can be cited. 1) Sliding parts of the type of control claws used as individual parts with the cover body include: a body; a pull tab, which can be rotated in the front-rear direction, and the shaft portion that becomes the center of the rotation is arranged on the upper wing plate; the control claws It is placed between the front mounting post and the rear mounting post on the shaft portion and controls the body to be movable and immovable, and the swinging convex portion of the front end thereof is fitted into the receiving recess, and the rear end portion thereof The claw portion protrudes from the claw hole to the sprocket path; and the cover body is installed in a manner capable of swinging up and down with respect to the front mounting post and the rear mounting post, and the upper plate portion and the side plate portion are covered and controlled from above and from the side. Claws, and the upper plate portion presses the control claw downward by a restoring force of a plate spring portion extending from the front end of the upper plate portion along the front surface of the front mounting post. In addition, the claw portion is accommodated in at least the first claw hole portion. 2) A slider of a type in which the control claw is a part of the cover is provided with: a body; a pull tab that can be rotated in the front-rear direction, and a shaft portion that becomes the center of the rotation is disposed on the upper wing plate; and a cover that It is installed in such a manner that it can swing up and down with respect to the front mounting post and the rear mounting post, and the upper plate part and the side plate part cover the front mounting post from above and from the side, and the claw part extending downward from the side plate part is accommodated in the claw. Hole, and the lower portion of the claw portion is pressed into the sprocket path by the restoring force of the plate spring portion extending from the front end of the upper plate portion along the front surface of the front mounting post. The claw portion is accommodated in the second claw hole portion. [Effects of the Invention] When the body of the slider for a slide fastener of the present invention uses a claw portion of a control claw integrated with a cover body, the claw portion needs only to be stored in the first claw hole portion and the second claw hole portion. If the size of the direction is longer, when the control claw is a separate part from the cover, only the claws are to be accommodated in the first and second claw hole portions, and The front end of the control claw may be stored in the receiving recess. In this way, the body of the present invention can be used for a slider of a type in which the control claw is a part of the cover, and a slider of a type in which the control claw is different from the cover.

The shaft portion 21 is disposed on the body 1, and a control claw 3 is disposed on the shaft portion 21. The control claw 3 includes a pushed-up portion 31 that extends forward and backward on the upper side of the shaft portion 21 and is pushed up by the shaft portion 21; and a claw portion 32 that faces downward from a rear portion of the pushed-up portion 31. In addition, since the control claw 3 is provided with the claw portion 32 on the front side more than the rear end of the pushed-up portion 31, the rear end portion 31 c of the pushed-up portion 31 projects further rearward than the claw portion 32. Details of the pushed-up part 31 will be described later. The cover 4 includes an upper plate portion 41 which faces the upper surface of the main body 1, a plate spring portion 42 which extends downward from the front end of the upper plate portion 41, and a pair of side plate portions 43, 43 which are provided from above. The left and right side ends of the plate portion 41 extend downward. The cover 4 is formed by bending a metal plate by press working. The thickness of the cover 4 (side plate portion 43) is smaller than the thickness of the control claw 3 in the left-right direction. The details of the cover 4 will be described later. The body 1 is used to engage and disengage the sprocket. As shown in FIGS. 3 to 5, the main body 1 is provided with sprocket paths 1 a on its front and rear surfaces and chain cloth grooves 1 b on its left and right sides as space portions. The sprocket paths 1 a penetrate in the front-back direction and provide a pair of sprocket rows. As a result, the above-mentioned chain cloth groove 1b penetrates in the front-back direction and allows a pair of fastener chain cloths to pass through. The sprocket path 1a is a space portion whose front portion is separated by left and right. In other words, the front part of the sprocket path 1a is branched from the left and right, and the back part of the sprocket path 1a is merged to form a path toward the rear. In order to form the sprocket path 1a and the chain cloth groove 1b, the body 1 includes an upper wing plate 11 covering the upper side of the sprocket path 1a, and a lower wing plate 12 spaced apart from the upper wing plate 11 at a lower interval.

The upper wing plate 11 and the lower wing plate 12 are plates having a vertical direction as a thickness direction. The upper wing plate 11 is located between the front mounting column 15 and the rear mounting column 16 and is provided with a claw hole 11 a at a position closer to the rear mounting column 16. The claw hole 11 a is used to make the claw portion 32 protrude into the sprocket path 1 a. The claw hole 11a is formed in a thickness direction, that is, a vertical direction, of the claw hole 11a. As shown in FIG. 1, the claw hole 11 a includes a first claw hole portion 11 b and a second claw hole portion 11 c that can receive a claw portion of a control claw that is a separate component from the cover. The first claw hole portion 11b and the second claw hole portion 11c are adjacent to each other in the width direction of the upper wing plate 11. In this embodiment, they are connected (communicated) in the width direction. The first claw hole portion 11b is located on the center side of the upper wing plate 11 in the width direction than the second claw hole portion 11c. Both the first claw hole portion 11b and the second claw hole portion 11c are rectangular in plan view, and each has a dimension (length) in the front-back direction longer than a dimension in the width direction. The first claw hole portion 11b and the second claw hole portion 11c have different sizes in the front-rear direction. Further, regarding the size in the front-rear direction, the first claw hole portion 11b is shorter than the second claw hole portion 11c. In addition, the positions of the first claw hole portions 11b and the second claw hole portions 11c are different from each other in the front and rear positions 11b1 and 11c1. More specifically, the front surface 11b1 of the first claw hole portion 11b is located further rearward than the front surface 11c1 of the second claw hole portion 11c. Further, in a plan view, the front surface 11b1 of the first claw hole portion 11b is lowered in a stepwise manner relative to the front surface 11c1 of the second claw hole portion 11c. In addition, the claw hole 11a is generally a person with a mold release slope, and the lengths in the width direction and the front-rear direction become wider from below to upward. FIG. 2 shows the relationship between the claw hole 11a and the claw portion 32 of the control claw when the slider is in the automatic stop state. Moreover, since the claw hole 11a is a person with a mold release gradient as described above, in FIG. 2, the claw hole 11a is simplified, and only the lower end of the claw hole 11a is shown. The first claw hole portion 11b and the second claw hole portion 11c accommodate the claw portions 32 of the control claw 3 in a coordinated manner. In order to explain this relationship in detail, a centerline (hereinafter, referred to as a “centerline”) L of the left-right direction of the upper wing 11 is used. In addition, the center line L corresponds to a line bisected in the widthwise direction by a pair of sprocket rows F3 and F3 in an engaged state. Details of the above relationship are described below. The front surface 32a of the claw portion 32 is in partial contact with the front surface 11m of the claw hole 11a. More specifically, the front surface 32a of the claw portion 32 comes into contact with the front surface 11b1 of the first claw hole portion 11b and is separated from the front surface 11c1 of the second claw hole portion 11c (non-contact). One of the left and right side surfaces 32b, 32c (the side surface 32c farther from the center line L) of the claw portion 32 is in contact with the side surface (the side surface 11c2 farther from the center line L) of the second claw hole portion 11c. The other one of the left and right side surfaces 32b, 32c (the side surface 32c closer to the center line L) is not in contact with the side surface 11b2 of the first claw hole portion 11b. In addition, the rear surface 11b3 of the first claw hole portion 11b and the rear surface 11c3 of the second claw hole portion 11c are continuous in a line in the width direction.

The recessed portion 15b for the leaf spring portion includes a first recessed portion 15c that houses the first spring piece portion 42a, and a second recessed portion 15d that houses the second spring piece portion 42b. The second recessed portion 15 d is formed across both the front surface of the front mounting post 15 and the upper surface of the upper wing plate 11. The first recessed portion 15 c is formed on the upper surface of the front mounting post 15. The cover 4 is configured to swing up and down with respect to the main body 1 as follows. As shown in FIGS. 3 and 5, the side plate portion 43 of the cover body 4 includes: a side plate body portion 43 a extending downward from the left and right side ends of the upper plate portion 41; and a front protruding piece portion 43 b opposite to the side plate body portion 43 a. The lower portion protrudes forward; and the rear protruding piece portion 43c protrudes rearward with respect to the side plate body portion 43a. The front protruding piece portion 43b becomes a center portion when the cover body 4 swings, and the rear protruding piece portion 43c becomes a displacement portion when the cover body 4 swings. Therefore, the cover 4 uses the front portion of the side plate portion 43 as the center portion of the swing, and the rear portion of the side plate portion 43 as the displacement portion that moves up and down by swinging. In addition, when the rear portion of the cover 4 is displaced upward, the leaf spring portion 42 is elastically deformed and flexed, thereby generating a large restoring force that pushes the rear portion of the cover 4 together with the control claw 3 downward. In addition, the pair of side plate body portions 43a, 43a are provided with through holes 43a1 penetrating left and right, and openings formed below, respectively, in portions facing the sides. The through-hole 43a1 is a hole through which the shaft portion 21 of the pull-tab 2 passes and rotatably supports the pull-tab 2. Regarding the configuration in which the cover body 4 can swing up and down relative to the main body 1, the main body 1 is described below. As shown in FIGS. 3 and 5, the main body 1 is provided on the lower part of the left and right sides of the front mounting post 15 and includes the front receiving part 15 e in which the left and right front protruding pieces 43 b cannot be moved up and down. The rear accommodating portion 16e is provided to accommodate the rear protruding piece portion 43c in a vertically displaceable manner. The front accommodating portion 15e is recessed on the side of the front mounting post 15 and forms an opening at the rear. The size of the front receiving portion 15e is slightly longer than the size of the front protruding piece portion 43b. The front accommodating portion 15e is used to support the front support portion 15e in a manner capable of swinging up and down. In addition, a portion of the side surface of the front mounting post 15 that is upper than the front support portion 15e protrudes to the front support portion 15e in a stepwise manner and protrudes to the front protrusion portion 15f laterally. The front protruding portion 15f prevents the protruding piece portion 43b stored in the front support portion 15e from being displaced upward. The rear accommodating portion 16e is recessed on the side of the rear mounting post 16 and forms an opening in the front. In addition, the upper and lower dimensions of the rear housing portion 16e are sufficiently longer than the upper and lower dimensions of the rear protruding piece portion 43c. The rear accommodating portion 16e is used to support the cover 4 in a manner capable of swinging up and down to support the rear support portion 16e. In addition, a portion of the side surface of the rear mounting post 16 that is upward with respect to the rear support portion 16e is a protruding portion 16f that protrudes laterally in a stepwise manner with respect to the rear support portion 16e. The rear protruding portion 16f defines an upper limit position in the moving range of the protruding piece portion 43c after being displaceable in the vertical direction. The slider S of the first embodiment is assembled as follows. First, the operation of mounting the pull tab 2 on the main body 1 is to insert the shaft portion 21 of the pull tab 2 between the front mounting post 15 and the rear mounting post 16 (the protruding portion 19) relative to the main body 1. Next, the operation of attaching the control claw 3 to the main body 1 is to move the control claw 3 downward from above the shaft portion 21, and insert the swinging convex portion 31a into the receiving recessed portion so that the control claw 3 covers the shaft portion 21 from above. 18, and insert the claw portion 32 into the claw hole 11a. That is, the control claw 3 is not displaced in the front-back direction during the operation of mounting the control claw 3 on the body 1. Finally, the operation of installing the cover 4 on the main body 1 is to install the cover 4 on the front mounting post 15 and the rear mounting post 16. Furthermore, since the operation of attaching the cover 4 of the slider S of the first embodiment to the body 1 is the same as the operation of attaching the cover of the slider of the second embodiment to the body, the sliding of the second embodiment Detailed description. When the slider S of the first embodiment described above is in a state where the shaft portion 21 of the pull-tab 2 is placed on the upper surface of the upper wing plate 11 as shown in FIG. 6 (A), the upper plate portion 41 of the cover body 4 and The control claw 3 is in contact, and the lower end portion of the leaf spring portion 42 is in contact with the front surface of the main body 1, so the leaf spring portion 42 is slightly deflected. By the restoring force of the plate spring portion 42, the upper plate portion 41 of the cover 4 presses the control claw 3 downward, so that the claw portion 32 protrudes deeper into the sprocket path 1 a. Moreover, the head (lower part) of the claw portion 32 is embedded between adjacent sprocket teeth in a sprocket row. In addition, the front surface 32a of the upper portion of the claw portion 32 is in contact with the front surface 11b1 of the first claw hole portion 11b, and the rear end portion (the placed portion) 31c of the pushed portion 31 is placed on the placing portion 11z. Therefore, the slider S of the first embodiment becomes immovable. In particular, even if the slider S of the first embodiment is intended to move backward, as long as the pull tab 2 is not operated, the contact state between the front surface 32a of the claw portion 32 and the front surface 11b1 of the first claw hole portion 11b is maintained. The slider S of the form becomes immovable. Moreover, at this time, as long as the upper plate portion 41 of the cover body 4 is restricted from moving upwards by the restoring force of the plate spring portion 42, the upper plate portion 41 and the control claw 3 of the cover body 4 may not be moved. Contact (also in a close state). Incidentally, as described above based on FIG. 2, the rear surface 32 d of the claw portion 32 and the rear surface 11 n of the claw hole 11 a (the rear surface of the first claw hole portion 11 b 11 b 3 and the rear surface of the second claw hole portion 11 c) are not in contact with each other. (Interval), and using this interval, the claw portion 32 of the control claw 3 can be displaced with the swinging convex portion 31a as the center, while being displaced toward the rear and upward. Therefore, in the automatic stop state, the claw hole 11 a is in a state with a gap behind the control claw 3. In addition, the operation of operating the pull tab 2 of the slider S of the first embodiment is to pull the pull tab 2 and, in conjunction with the pull operation, the control claw 3 is raised toward the rear side. In this way, as shown in FIG. 6 (B), the slider S of the first embodiment pushes the control claw 3 upward and away from the upper surface of the upper wing plate 11 by the shaft portion 21 of the pull-tab 2. At this time, the control claw 3 is in contact with the upper plate portion 41 of the cover body 4, and the front portion of the side plate portion 43 is used as the center portion of the swing to lift the cover body 4 upward. At this time, the leaf spring portion 42 is largely deflected, and the leaf spring portion 42 generates a large restoring force. This restoring force is a force to press the cover body 4 and the control claw 3 downward. When the control claw 3 is pushed up by the shaft portion 21 of the pull-tab 2, the claw portion 32 rises to a state where the front surface 32a of the upper portion of the claw portion 32 is separated from the front surface 11b1 of the first claw hole portion 11b. And the end portion 31c behind the pushed-up portion 31 is away from the mounting portion 11z. At this time, compared with the case where the shaft portion 21 is placed on the upper surface of the upper wing plate 11, the protrusion length of the claw portion 32 into the sprocket path 1a becomes shorter, or the claw portion 32 no longer protrudes into the sprocket path 1a. Therefore, the head (lower part) of the claw portion 32 is withdrawn from between adjacent teeth in a sprocket row, so that the slider S of the first embodiment becomes movable. In this way, the protruding length of the claw portion 32 changes according to the up and down position of the shaft portion 21, and the claw portion 32 of the control claw 3 controls the movement of the slider S (body 1). In addition, the slider S1 of the second embodiment of the present invention is also used for the ring chain sprocket. As shown in FIG. 7, the slider S1 of the second embodiment of the present invention is the same as the slider S of the first embodiment in that the body 1 and the pull tab 2 have the same structure, so there is no control. The shape of the claw 3 and the cover 4A is different. That is, as shown in FIG. 1, the body 1 of the slider S1 of the second embodiment has the same configuration as the body 1 of the slider S of the first embodiment. Moreover, the slider S1 of the second embodiment includes three parts including the main body 1, the pull-tab 2, and the cover 4A as individual parts. The differences will be described below. The cover body 4A is different from the cover body 4 of the slider S of the first embodiment in that the cover body 4A includes an upper plate portion 41, a plate spring portion 42, and a pair of side plate portions 43, 43 and is different in that: The claw portion 32 of the control claw 3 extends downward from one of the pair of side plate portions 43, and more specifically, from the side plate portion 43 rearward of the through hole 43a1. In this embodiment, the control claw 3 is composed of only the claw portion 32. As for the width in the front-rear direction, the claw portion 32 has a shape where the head portion (lower portion) is tapered. Both the front surface and the rear surface of the claw portion 32 approach each other as they go downward. As shown in FIG. 8, the claw portion 32 is accommodated in the second claw hole portion 11 c. The operation of attaching the cover 4A to the main body 1 is as follows. First, as shown by the one-dot chain line in FIG. 9 (B), the rear projection portion 43c of the cover 4A is inserted into the rear support portion 16e of the rear mounting post 16, and the front projection portion 43b of the cover 4A is mounted relative to the front The front support part 15e of the pillar 15 is arrange | positioned on the upper side, and the cover body 4A is a state inclined with respect to a horizontal. At this time, the head (lower part) of the claw portion 32 is in a state close to the front surface 11m (the front surface 11c1 of the second claw hole portion 11c) of the claw hole 11a. Next, the front side of the cover 4A is pushed in downward. In this way, as shown by the solid line in FIG. 9 (B), the cover body 4A is gradually rotated with the rear protruding piece portion 43c as the center and is tilted forward, and the claw portion 32 of the control claw 3 together with the cover body 4A The inner side of the claw hole 11a faces downward and the rear side thereof. If the front side of the cover 4A is further pushed downward, as shown by the solid line in FIG. 9 (A), the front protruding piece 43b of the cover 4A is housed in the support portion 15e before the front mounting column 15, and the cover 4A The claw portion 32 is accommodated in a state spaced back and forth with respect to the second claw hole portion 11c. Specifically, as shown in FIG. 8, the front surface 32 a of the claw portion 32 is not in contact with the front surface 11 c 1 of the second claw hole portion 11 c, and the rear surface 32 d of the claw portion 32 is not in contact with the rear surface 11 c 3 of the second claw hole portion 11 c. Moreover, the left and right side surfaces 32b and 32a of the claw portion 32 and the left and right side surfaces of the claw hole 11a (the side surface 11b of the first claw hole portion 11b 2 and the side surface 11c2 of the second claw hole portion 11c) are not in contact with each other. Furthermore, the operation of installing the cover 4A of the slider S1 of the second embodiment on the body 1 is also the operation of installing the control claw 3 on the body 1, and the operation of installing the cover 4 of the slider of the first embodiment on The operation of the main body 1 is the same. Also, in the case of the slider S1 of the second embodiment, if the cover body 4A is mounted on the body 1, the cover body 4A is pushed downward by the restoring force of the plate spring portion 42, and will be used as The claw portion 32 of a part of the cover 4A is pressed into the sprocket path 1a. The operation of operating the pull-tab 2 of the slider S1 of the second embodiment is to pull the pull-tab 2. In conjunction with the pull-up operation, the control claw 3 is raised toward the rear side. In any of the above operations, the control claw 3 is displaced backward. Therefore, in the automatic stop state, the claw hole 11 a is in a state where there is a gap between the claw portion 32 of the control claw 3 and the front and back sides. As shown in FIGS. 1, 2 and 8, the slider S of the first embodiment and the slider S1 of the second embodiment both use the same body 1. Therefore, the main body 1 used for the sliders S1 and S2 of the two embodiments has the following effects. When the main body 1 is the case where the claw portion 32 of the control claw 3 integrated with the cover 4A is used like the slider S1 of the second embodiment, the claw portion 32 is housed only in the second claw hole portion 11c. Incidentally, the second claw hole portion 11c has a longer dimension in the front-rear direction than the first claw hole portion 11b, and the claw portion 32 is accommodated in the longer second claw hole portion 11c. In addition, when the main body 1 is used in the same manner as the slider S of the first embodiment and the cover 4 is a separate part of the control claw 3, the front end of the control claw 3, that is, the swinging convex portion 31a is accommodated in the receiving recess 18, And the claw part 32 is accommodated in both the 1st claw hole part 11b and the 2nd claw hole part 11c. Incidentally, the size of the first claw hole portion 11b in the front-back direction is shorter than that of the second claw hole portion 11c, and the claw portion 32 is housed in two of the shorter second claw hole portion 11c and the longer claw hole portion 11b. By. Furthermore, since the claw portion 32 is accommodated in both the first claw hole portion 11b and the second claw hole portion 11c, the claw can be shortened compared to a case where the claw portion 32 is accommodated only in the first claw hole portion 11b. The width dimension of the hole 11a. In this way, the main body 1 can be used for the slider S of a type different from the control claw 3 and the cover 4, and the slider S1 of the type where the control claw 3 is a part of the cover 4A. In addition, although the slider S of the first embodiment has the control claw 3 and the cover 4 as separate parts, as long as the cover 4 formed by integrating the control claw 3 is disassembled after assembly, the first Slider S1 of the second embodiment. In addition, although the slider S1 of the second embodiment uses the cover body 4A integrated with the control claw 3, as long as it is disassembled after assembly, and the control claw 3 and the cover body 4 of individual parts are prepared, the first A sliding member S1 of an embodiment.

One through hole 11d is a first claw hole portion 11d, and the other through hole 11e is a second claw hole portion 11e. Both the first claw hole portion 11d and the second claw hole portion 11e are rectangular in a plan view, and both have a dimension (length) in the front-back direction longer than a dimension in the width direction. Further, the upper wing plate 11 has the first claw hole portion 11d and the second claw hole portion 11e adjacent to each other in the width direction, and includes a partition portion 11s between the first claw hole portion 11d and the second claw hole portion 11e. The partition portion separates the first claw hole portion 11d and the second claw hole portion 11e in the width direction. Therefore, the first claw hole portion 11b and the second claw hole portion 11c are separated in the width direction by the partition portion 11s. Moreover, in this embodiment, the upper surface of the partition part 11s is provided with the bulging part 11t bulged from the upper surface of the upper wing plate 11. A first claw hole portion 11d is formed on one side and a second claw hole portion 11e is formed on the other side with respect to the centerline L of the upper wing plate 11 in the left-right direction. The second claw hole portion 11e is further away from the center line L than the first claw hole portion 11d. In the example shown in the figure, there is a gap between the second claw hole portion 11e and the center line L. The first claw hole portion 11b has no gap between the upper end and the center line L, and the lower end and the center line. There is a space between L. The first claw hole portion 11d and the second claw hole portion 11e have different lengths in the front-rear direction, and the size of the first claw hole portion 11d in the front-rear direction is shorter than the size of the second claw hole portion 11e in the front-rear direction. Regarding the position in the front-rear direction, the upper end of the front surface 11d1 of the first claw hole portion 11d is formed at the same position as the upper end of the front surface 11e1 of the second claw hole portion 11e. Regarding the position in the front-rear direction, the lower end of the front surface 11d1 of the first claw hole portion 11d is formed closer to the front side than the lower end of the front surface 11e1 of the second claw hole portion 11e. On the other hand, the rear surface 11d3 of the first claw hole portion 11d is formed closer to the front side than the rear surface 11e3 of the second claw hole portion 11e. As for the dimension in the width direction, the first claw hole portion 11b is formed wider than the second claw hole portion 11c. In this case, as shown in FIG. 11, the first claw hole portion 11 d receives and covers the claw portion 32 of the control claw 3 which is a separate component. Further, the upper wing panel 11 includes a mounting portion 11z which is adjacent to the rear side with respect to the first claw hole portion 11d, and mounts the rear end portion 31c of the pushed-up portion 31 of the control claw 3. In addition, although the slider of the third embodiment is not shown, as in the first embodiment, it includes four parts: a body, a control claw, a cover, and a pull tab. Moreover, as shown in FIG. 12, the 2nd claw hole part 11e accommodates the claw part 32 of the control claw 3 integrated with a cover. In addition, although not shown, the slider according to the fourth embodiment is provided with three parts: a main body, a cover, and a pull tab, as in the second embodiment. The body 1A of the slider of the third and fourth embodiments is the same as the body 1 of the slider of the first and second embodiments, and can be used for a slider of a type different from the body of the control claw 3 and the control claw. 3 is a type of sliding part of the cover. The sliders of the fifth and sixth embodiments of the present invention are also those made to cope with independent sprocket. More specifically, in this embodiment, the sprocket row includes resin-made sprocket. FIG. 13 shows the relationship between the body 1B and the control claw 3 of the slider of the fifth embodiment, and FIG. 14 shows the relationship between the body 1B and the control claw 3 of the slider of the sixth embodiment. The sliders of the fifth and sixth embodiments also use the same body 1B as the sliders of the third and fourth embodiments. Further, the upper wing plate 11 of the main body 1B includes a claw hole 11a, and the claw hole 11a includes a first claw hole portion 11d and a second claw hole portion 11e which are partitioned in the width direction by the partition portion 11s. In addition, the body 1B of the slider of the fifth and sixth embodiments is different from the body 1A of the slider of the third and fourth embodiments in that there is no gap between the lower end of the first claw hole portion 11b and the center line L. aspect. The distance between the second claw hole portion 11c and the center line L is the same as that of the sliders of the third and fourth embodiments. Incidentally, although the slider of the fifth embodiment is not shown, as in the first embodiment, it includes four parts: a body, a control claw, a cover, and a pull tab. Moreover, although the slider of the sixth embodiment is not shown, as in the second embodiment, it includes three parts: a body, a cover, and a pull tab. In addition, the slider body 1B of the fifth and sixth embodiments is similar to the slider body 1 of the first and second embodiments, and can be used to control sliders of different types from the claw 3 and the cover body. And the control claw 3 is a sliding member of a type that is a part of the cover. The sliders of the above-mentioned first and second embodiments are used for ring fastener elements. As for the bodies used for these sliders, the claw holes are provided with a first claw hole portion and a second claw which are connected (communicated) in the width direction. Hole. The sliders of the third to sixth embodiments are used for independent sprocket. For the bodies used for such sliders, the claw holes include a first claw hole portion and a first claw hole which are partitioned in the width direction by a partition portion. 2 claw hole. However, it is not determined which of the sprocket rows that can be used for the main body is a hoop sprocket or an independent sprocket depending on the presence or absence of a partition. For example, when the body is provided with a first claw hole portion and a second claw hole portion that communicate with each other in the width direction, the body can be used not only for a chain link sprocket but also for an independent sprocket. FIG. 15 shows an embodiment (hereinafter, referred to as a “change example”) of the change of the body 1 in the sliders of the first and second embodiments. Regarding the claw holes 11a of the body 1C of the modified example, the positions of the first claw hole portions 11b and the second claw hole portions 11c are different from each other on the front and rear surfaces 11b3 and 11c3. More specifically, the rear surface 11b3 of the first claw hole portion 11b is located further forward than the rear surface 11c3 of the second claw hole portion 11c. In addition, in a plan view, the rear surface 11c3 of the second claw hole portion 11c is lowered rearward in a stepwise manner with respect to the rear surface 11b3 of the first claw hole portion 11b. In addition, the first claw hole portion 11b and the second claw hole portion 11c are such that the positions of the front surfaces 11b1 and 11c1 of each other are continuously continuous in the width direction at the upper ends of the first claw holes 11b and 11c1, and are different from each other at the lower ends. More specifically, the lower end (rear end) of the front surface 11b1 of the first claw hole portion 11b is located further forward than the lower end (rear end) of the front surface 11c1 of the second claw hole portion 11c. In addition, in a plan view, the front surface 11c1 of the second claw hole portion 11c is lowered in a stepwise manner in a stepwise manner with respect to the front surface 11b1 of the first claw hole portion 11b. The upper wing plate 11 is provided between the front mounting post 15 and the rear mounting post 16 and includes a mounting portion 11z adjacent to the first claw hole portion 11b of the claw hole 11a. That is, the mounting portion 11z is not formed in the full length in the width direction of the claw hole 11a, but is formed in the width direction in only the first claw hole portion 11b, and is not formed in the second claw hole portion 11c. In this way, the body 1C of the modified example can be used for independent sprocket. Therefore, if the body 1C of the modified example and the body 1 of the first and second embodiments are considered, the body in which the first claw hole portion 11b and the second claw hole portion 11c are connected in the width direction can not only cope with the chain link sprocket, It can also handle independent sprocket teeth. The slider S2 of the seventh embodiment of the present invention is different from the slider S of the first embodiment in the mounting portion 11z1 of the main body 1D and the mounted portion 33 of the control claw 3. The main body 1D is formed by adjoining the mounting portion 11z1 to the front with respect to the claw hole 11a (more specifically, the first claw hole portion 11a). On the other hand, the control claw 3 projects the mounted portion 33 forward from the upper front surface of the claw portion 32. In this case, the control claw 3 includes a pushed-up portion 31, a claw portion 32, and a mounted portion 33 that is different from the pushed-up portion 31 and the claw portion 32. In this way, when the slider S2 cannot be moved, the mounted portion 33 is placed on the mounting portion 11z1. Moreover, the head (lower part) of the claw portion 32 is inserted between adjacent sprocket teeth in a pair of sprocket rows. The present invention is not limited to the above-mentioned embodiments, and may be appropriately changed within a range not departing from the gist thereof. For example, in this embodiment, the protruding portion 19 is adjacent to the rear side of the front mounting post 15, but in the present invention, it is not limited to this, and may be far from the rear of the front mounting post 15. In this case, although not shown, it is sufficient to form a receiving recessed portion in the central portion in the front-rear direction and the width direction of the protruding portion 19 in a plan view.
