[0007] Patent Document 2: Chinese Utility Model No. 209235120 Summary of the Invention

[0008] However, in the cord end fixing part changing device described in Patent Document 1, the bottom of the first and second pull heads is not covered by the connecting structure. Therefore, if the item is clothing or the like, the first and second pull heads may touch the body and cause a foreign body sensation.

[0009] Furthermore, in the double-pull zipper described in Patent Document 2, depending on the different connection methods relative to the two fabric strips, the first and second pulls may be exposed to the outside in the part not covered by the connecting cover, resulting in a poor appearance.

[0010] The purpose of this invention is to provide a zipper pull structure and zipper pull cover that can reduce the feeling of foreign objects and have a good appearance.

[0011] The zipper pull structure of the present invention comprises: a first zipper pull and a second zipper pull that are slidably movable, such that a row of zipper teeth arranged along a pair of zipper straps is separated from each other; and a zipper pull cover that holds the first zipper pull and the second zipper pull in a manner such that the first zipper pull and the second zipper pull are opposite each other. The zipper pull cover comprises: a lower cover that covers the first zipper pull and the second zipper pull from below; and an upper cover that engages with the lower cover and covers the first zipper pull and the second zipper pull from above. The lower cover has a cord mounting portion for mounting cords, and an operation connection portion for connecting an operation member for sliding operation of the first zipper pull and the second zipper pull is formed between the lower cover and the upper cover.

[0012] In the zipper head structure of the present invention, the first zipper head may include: a zipper head body for the chain teeth to pass through; a locking member that engages with the chain teeth in a sliding direction; and a switching member that switches the engaging and disengaged states of the locking member. In the operation connection portion, the operation member is arranged below the switching member in such a way that the locking member can be switched from the engaging state to the disengaged state via the switching member.

[0013] In the zipper structure of the present invention, the portion of the second zipper side in the upper cover may be located above the switching member and formed in a manner that allows for elastic deformation in the vertical direction.

[0014] In the zipper pull structure of the present invention, the lower cover may have an engaging protrusion having an engaging portion at its top and protruding upwards, and the upper cover may have an engaging groove for the engaging portion to be disposed therein; an engaging guide for guiding the engaging portion toward the engaging groove; and an elastic sheet continuous with the engaging groove, the elastic sheet being configured to be able to be pushed up by the engaging portion guided by the engaging guide.

[0015] In the zipper pull structure of the present invention, the engaging guide portion may also have: a sliding guide surface that guides the engaging portion in a sliding direction; an inclined guide surface that is continuous with the sliding guide surface and inclined upward; and an engaging receiving surface that is continuous with the inclined guide surface and receives the engaging portion from below, wherein the elastic sheet portion is configured such that the engaging portion guided by the sliding guide surface presses against the elastic sheet portion.

[0016] In the zipper head structure of the present invention, both the first zipper head and the second zipper head may be composed of a zipper head body.

[0017] In the puller structure of the present invention, the lower surface of the lower cover may also be formed by a flat surface.

[0018] The zipper pull cover of the present invention is a zipper pull cover that holds a first zipper pull and a second zipper pull in a manner in which the first zipper pull and the second zipper pull are opposite each other. It comprises: a lower cover that covers the first zipper pull and the second zipper pull from below; and an upper cover that engages with the lower cover and covers the first zipper pull and the second zipper pull from above. The lower cover has a cord mounting portion for mounting a cord or similar accessory. An operation connection portion is formed between the lower cover and the upper cover for connecting an operation member for sliding operation of the first zipper pull and the second zipper pull.

[0019] According to the present invention, a zipper pull structure and zipper pull cover that can reduce the feeling of foreign objects and have a good appearance can be provided. Attached Figure Description

[0034] [Structure of the first embodiment]

[0035] Hereinafter, the first embodiment of the present invention will be described with reference to the accompanying drawings.

[0036] exist Figures 1-5 In the first embodiment, the pull-out cover 10 is composed of two components: a lower cover 20 and an upper cover 30 made of synthetic resin. This is achieved through... Figure 6 The zipper pull structure 1 is formed by holding the first zipper pull 50 and the second zipper pull 60 with the zipper pull cover 10. The zipper pull structure 1 is used in adjustable zippers that adjust the size of clothing, such as the abdominal circumference and sleeve circumference.

[0037] In the following description, the sliding direction of the slider structure 1 is set as the X-axis direction, the direction orthogonal to the X-axis direction is set as the Y-axis direction (left-right direction, width direction), and the direction orthogonal to the X-axis and Y-axis directions is set as the Z-axis direction (up-down direction, thickness direction).

[0038] The first zipper head 50 consists of a zipper head body 51, a locking pin 52 and a switching element 53 installed on the zipper head body 51 as locking components, wherein the zipper head body 51 is for inserting a row of chain teeth 3 that are able to engage and disengage with each other along a pair of zipper straps 2.

[0039] The pull head body 51 is integrally connected to the upper plate 512 and the lower plate 513 via the column 511, and a mounting part 514 for mounting the locking pin 52 and the switching member 53 is formed on the upper surface of the upper plate 512.

[0040] The locking pin 52 has: an engaging end 521 that moves between the upper plate portion 512 and the lower plate portion 513; and a leaf spring portion 522 that allows the engaging end 521 to move in and out. In addition, it is not limited to the leaf spring portion 522, but may also have a force-applying portion such as a helical spring that applies force to the engaging end 521 in a way that allows it to move in and out.

[0041] The switching member 53 is plate-shaped and has a shaft portion 531 that is rotatably mounted to the mounting portion 514. The shaft portion 531 is disposed between the leaf spring portion 522 of the locking pin 52 and the upper plate portion 512. A hole portion 532 is formed in the switching member 53 for a portion of the mounting portion 514 and the engaging protrusion 23 described later. In addition, an anti-detachment hole portion 533 is formed in the switching member 53 at a position further away from the front end than the hole portion 532 for the anti-detachment portion 312 of the upper cover 30 described later to be disposed.

[0042] In the first zipper pull 50 configured as such, a pair of zipper teeth 3 of the zipper tape 2 are inserted between the upper plate portion 512 and the lower plate portion 513. The engaging end 521 of the locking pin 52 protrudes downward from the upper plate portion 512 and is engaged with the zipper teeth 3 in the X-axis direction. Therefore, the zipper pull structure 1 is held in a predetermined position and cannot slide along the pair of zipper tapes 2.

[0043] Furthermore, if the shaft portion 531 of the switching member 53 is lifted upward by the operation of the operating member 5 (described later), the leaf spring portion 522 of the locking pin 52 elastically deforms upward and the engaging end 521 is inserted into the upper plate portion 512, becoming a non-engaged state that is disengaged from the chain teeth 3. Therefore, the zipper pull structure 1 becomes capable of sliding along the pair of zipper straps 2.

[0044] Furthermore, the first zipper 50 can adopt an existing zipper 50 with a locking mechanism, so there is no need to redesign the first zipper 50, thus enabling cost reduction.

[0045] The second zipper pull 60 consists of a zipper pull body 61 through which a pair of zipper teeth 3 are inserted.

[0046] The zipper head body 61 is integrally connected to the upper plate portion 612 and the lower plate portion 613 by means of the column portion 611. Since the aforementioned locking pin 52 and switching member 53 are not installed on the zipper head body 61, the structure corresponding to the mounting portion 514 is not formed on the upper plate portion 612, and is formed on a generally flat upper surface with few undulations.

[0047] Furthermore, the second zipper pull 60 can utilize the zipper pull body from existing zippers, thus enabling cost reduction. Additionally, it is easier to reduce the thickness of the zipper pull structure 1 in the Z-axis direction by an amount equivalent to the absence of a structure with a mounting portion 514 as described above.

[0048] The lower cover 20 includes: a lower cover body 21, which is configured to cover the first pull head 50 and the second pull head 60 from below; a pair of lower retaining grooves 22 for the first pull head 50 and the second pull head 60; a locking protrusion 23, which has a locking portion 231 at its top end that engages with the upper cover 30; and a cord / strap mounting portion 24, which is capable of mounting cord / strap 6 (see reference). Figure 6 Here, the cord type 6 is connected to a specific part of clothing or other items, and the specific part is tightened or loosened by the sliding movement of the pull head structure 1.

[0049] The lower surface 211 of the lower cover body 21 is formed as a flat surface. The cord mounting part 24 is formed by a mounting hole in the lower cover body 21 at the end on the side where the first pull head 50 is disposed, which is formed in the X-axis direction.

[0050] A pair of lower retaining grooves 22 are formed on the surface of the lower cover body 21 opposite to the upper cover 30, and are configured with groove shapes corresponding to the shapes of the lower plate portions 513 and 613 of the slider bodies 51 and 61. The pair of lower retaining grooves 22 are arranged opposite to each other in the X-axis direction, and the slider bodies 51 and 61 disposed in the pair of lower retaining grooves 22 are as follows: Figure 5 The position is shown with the shoulders facing each other.

[0051] The engaging protrusion 23 is formed in such a way that it protrudes upward from the lower cover body portion 21 and is disposed between a pair of lower retaining groove portions 22. The engaging portion 231 protrudes from the engaging protrusion 23 to both sides in the Y-axis direction.

[0052] The upper cover 30 has: an upper cover body portion 31, which is configured to cover the first pull head 50 and the second pull head 60 from above; an upper retaining groove portion 32, which is configured for the first pull head 50 and the second pull head 60; a pair of engaging groove portions 33, which are configured for a pair of engaging portions 231 of the lower cover 20; and a pair of engaged portions 34, which engage with the pair of engaging portions 231 in the pair of engaging groove portions 33.

[0053] An anti-slip portion 312 is formed in the anti-slip hole portion 533 of the switching member 53 in a downward protruding manner on the upper cover body portion 31.

[0054] The upper retaining groove 32 is formed on the surface of the upper cover body 31 opposite to the lower cover 20, and is configured with a groove shape corresponding to the upper plate 512, mounting part 514 and switching member 53 of the pull head body 51, and the upper plate 612 of the pull head body 61.

[0055] A pair of engaging grooves 33 are formed in a vertically penetrating manner in the central portion of the upper cover body 31 in the X-axis direction, and are arranged opposite to each other in the Y-axis direction. In addition, openings 331 of the pair of engaging grooves 33 are formed on the two edges of the upper cover body 31 in the Y-axis direction.

[0056] Thus, a pair of engaging grooves 33 are formed and configured such that the width of the central portion of the upper cover body 31 located between the pair of engaging grooves 33 in the Y-axis direction is smaller than the width of the end portions on either side of this central portion in the X-axis direction in the Y-axis direction. Therefore, the central portion of the upper cover body 31 can elastically deform in the Z-axis direction, and the portion of the upper cover 30 near the second pull head 60 can adjust accordingly to the lifting of the switching member 53 by the operating member 5. Figure 7 The figure shows elastic deformation in the Z-axis direction.

[0057] A pair of engaging portions 34 are formed in a pair of engaging grooves 33 on the side closer to the pull head body 51 than the opening 331. By respectively arranging a pair of engaging portions 231 of the lower cover 20 on the upper part of the pair of engaging portions 34, the lower cover 20 is engaged with the pair of engaging portions 231 in a snap-fit ​​manner.

[0058] The pull-out cover 10 is constructed by engaging the engaging portion 231 of the lower cover 20 with the engaging portion 34 of the upper cover 30. This engagement is performed as described below.

[0059] First, the upper cover 30 is positioned above the lower cover 20 and closer to the pull head body 51 in the X-axis direction. Next, the upper cover 30 is brought closer to the lower cover 20 in the Z-axis direction, and a pair of engaging portions 231 are positioned in a pair of engaging grooves 33.

[0060] Next, the upper cover 30 is moved relative to the lower cover 20 toward the pull head body 61 in the X-axis direction, so that a pair of engaging portions 231 engage with a pair of engaged portions 34. Thus, the pair of engaging portions 231 engage with the pair of engaged portions 34 in the X-axis and Z-axis directions, and engage with a pair of engaging grooves 33 in the Y-axis direction.

[0061] When the lower cover 20 and the upper cover 30 are engaged, an operation connection part 40 is formed between the lower cover 20 and the upper cover 30, which can connect the operation member 5. The operation member 5 slides along a pair of zipper straps 2 in the X-axis direction to slide the zipper head structure 1.

[0062] The operation connection part 40 is located at the center position in the X-axis direction opposite to the first pull head 50 and the second pull head 60, and in this embodiment, it is located at the center position in the X-axis direction of the upper cover 30.

[0063] In addition, the operating component 5 is composed of operating ropes and the like, and the materials and structure can be freely selected.

[0064] The following describes the assembly sequence of the slider structure 1.

[0065] First, prepare a first zipper pull 50 and a second zipper pull 60 with the zipper teeth 3 already inserted. The shoulder openings of the zipper pull bodies 51 and 61 are arranged opposite each other.

[0066] Next, the lower cover 20 is positioned below the first zipper head 50 and the second zipper head 60, and the lower plate portions 513 and 613 of the zipper head bodies 51 and 61 are respectively positioned in a pair of lower retaining groove portions 22, and the engaging protrusion 23 passes through between the zipper head bodies 51 and 61.

[0067] Next, the operating member 5 is positioned between the slider bodies 51 and 61, and the switching member 53 is tilted towards the second slider 60, thereby positioning the operating member 5 below the switching member 53. At this time, a portion of the mounting portion 514 of the first slider 50 and the top of the engaging protrusion 23 are inserted into the hole 532 of the switching member 53. Furthermore, the switching member 53 of the first slider 50 is positioned on the upper plate portion 612 of the second slider 60. Since the upper plate portion 612 does not have a structure equivalent to the mounting portion 514, nor is the switching member 53 installed there, the size of the slider structure 1 in the X-axis direction can be reduced compared to the case where these are present.

[0068] Next, the upper cover 30 is positioned above the first pull head 50 and the second pull head 60, and the operating member 5 passes through a pair of engaging slots 33. The mounting portion 514, locking pin 52, and switching member 53 of the first pull head 50 are positioned in the upper retaining slot 32. Simultaneously, as described above, the engaging portion 34 of the upper cover 30 engages with the engaging portion 231 of the lower cover 20. Here, the end portion of the upper cover 30 near the second pull head 60 in the X-axis direction touches the switching member 53 and is lifted by elastic deformation upwards. However, when the engaging portion 231 engages with the engaging portion 34, the anti-disengagement portion 312 is inserted into the anti-disengagement hole 533 of the switching member 53, and the lifted upper cover 30 returns to its original state as described above. The anti-disengagement portion 312 restricts the movement of the upper cover 30 relative to the lower cover 20 in the X-axis direction, thereby functioning as an anti-disengagement portion for the engaging portion 34 relative to the engaging portion 231.

[0069] With the lower cover 20 and the upper cover 30 engaged, the zipper cover 10 is configured to cover the first zipper 50 and the second zipper 60 from above and below, and to cover the sides of the upper plate portion 512 of the first zipper 50 and the upper plate portion 612 of the second zipper 60. The first zipper 50 and the second zipper 60 are held in a relative position by a pair of lower retaining grooves 22 and upper retaining grooves 32. Furthermore, the aforementioned operation connection portion 40 is formed between the lower cover 20 and the upper cover 30. In this embodiment, the operation connection portion 40 is composed of the engaging protrusion 23 of the lower cover 20, the second zipper 60, and the switching member 53 of the first zipper 50, with the operating member 5 inserted through the slits along the Y-axis defined by these components.

[0070] The zipper head structure 1 assembled as described above is used in an adjustable zipper in which the teeth 3 of a pair of zipper tapes 2 are inserted into a first zipper head 50 and a second zipper head 60, and the cord 6 installed in the cord mounting part 24 is connected to a specific part of clothing, etc., thereby adjusting the size of the specific part of clothing, etc., and tightening or loosening it.

[0071] In the normal state where the operating part 5 is not slidably operated in the adjustable zipper, such as Figure 6 As shown, the locking pin 52 is engaged with the chain teeth 3, therefore, the zipper pull structure 1 cannot slide and remains in position. Thus, the dimensions of specific parts of clothing or similar garments connected by cords or straps 6 remain constant.

[0072] If the operating element 5 is slidably moved along the X-axis in the adjustable zipper, then as follows: Figure 7 As shown, the switching member 53 is lifted upward by the operating member 5, and the leaf spring portion 522 of the locking pin 52 elastically deforms upward by the switching member 53. The engaging end 521 of the locking pin 52 is inserted into the upper plate portion 512, and the engagement between the engaging end 521 and the chain teeth 3 is released, resulting in a non-engaged state. Here, when the switching member 53 is lifted, the upper cover body portion 31 also undergoes elastic deformation, especially at the central portion of the upper cover body portion 31 with a small width in the Y-axis direction, where a large elastic deformation occurs, and the end portion on the side of the second pull head 60 is lifted upward. Thus, the end portion of the upper cover body portion 31, especially the portion closer to the second pull head 60 than the central portion, follows the lifting of the switching member 53, thereby maintaining the state in which the anti-slip portion 312 is inserted into the anti-slip hole portion 533, and thus preventing the upper cover 30 from slipping off.

[0073] If the sliding operation of the operating member 5 continues, the zipper head structure 1 slides along the pair of zipper straps 2. Since the operating member 5 passes through the pair of engaging grooves 33 from the operating connection part 40, the operating member 5 will not detach from the zipper head structure 1 in the X-axis direction even when the operating member 5 is slidable. During the sliding movement of the zipper head structure 1, one of the first zipper head 50 and the second zipper head 60 disengages the pair of chain teeth 3 from each other, causing the pair of chain teeth 3 to separate in the Y-axis direction, while the other of the first zipper head 50 and the second zipper head 60 engages the pair of chain teeth 3 with each other. Therefore, even if the zipper head structure 1 slides, the portion of the pair of zipper straps 2 where the zipper head structure 1 is not located remains engaged. By sliding the zipper head structure 1 in this way, the size of a specific part of clothing or the like connected with cords or straps 6 can be adjusted.

[0074] Furthermore, if the sliding operation of the operating member 5 ends, the switching member 53 is pressed down on the lower cover 20 side by the upper cover body 31 to restore its original shape from the elastic deformation state, and the leaf spring part 522 of the locking pin 52 is restored, thereby becoming an engaged state in which the engaging end 521 protrudes from the upper plate part 512 and engages with the chain teeth 3.

[0075] [Structure of the second embodiment]

[0076] The second embodiment of the present invention will now be described with reference to the accompanying drawings.

[0077] exist Figures 8 to 12 In the second embodiment, the pull-out cover 10B is composed of two components: a lower cover 20B and an upper cover 30B made of synthetic resin. This is achieved through... Figure 13 The first zipper pull 50B and the second zipper pull 60B are held in place by the zipper pull cover 10B, thus forming the zipper pull structure 1B. The zipper pull structure 1B is used in the same way as the aforementioned adjustable zipper pull structure 1.

[0078] exist Figures 8 to 14 In the diagram, the X-axis direction is set as the sliding direction of the slider structure 1B, the Y-axis direction, which is orthogonal to the X-axis direction, is set as the width direction (left-right direction) of the slider structure 1B, and the Z-axis direction, which is orthogonal to both the X-axis and Y-axis directions, is set as the thickness direction (up-down direction) of the slider structure 1B.

[0079] The first slider 50B and the second slider 60B are constructed in the same manner as the aforementioned second slider 60. Therefore, the same reference numerals are used in the accompanying drawings and detailed descriptions are omitted.

[0080] The lower cover 20B includes: a lower cover body portion 21B, which is configured to cover the first zipper pull 50B and the second zipper pull 60B from below; a pair of lower retaining grooves 22B for the first zipper pull 50B and the second zipper pull 60B; an engaging protrusion 23B having an engaging portion 232B at its top end that engages with the upper cover 30B; and a cord / strap mounting portion 24B for mounting cords / straps 6. The cords / straps 6 are connected to specific parts of clothing or other items in the same manner as described above.

[0081] The lower surface 211B of the lower cover body 21B is formed as a flat surface. The rope mounting part 24B is formed by a mounting hole in the lower cover body 21B that is formed in the X-axis direction at the end on the side where the second pull head 60B is located.

[0082] A pair of lower retaining grooves 22B are formed on the surface of the lower cover body 21B opposite to the upper cover 30B, and are configured with groove shapes corresponding to the shapes of the lower plate portions 513, 613 of the slider body 61. The pair of lower retaining grooves 22B are arranged opposite to each other in the X-axis direction, and the slider body 61 with the pair of lower retaining grooves 22B respectively disposed on the slider body 61. Figure 12The position is shown with the shoulders facing each other.

[0083] The engaging protrusion 23B is formed by protruding upward from the lower cover body portion 21B and is disposed between a pair of lower retaining groove portions 22B. The engaging portion 232B protrudes from the top of the engaging protrusion 23B to both sides in the Y-axis direction. The engaging protrusion 23B is formed in a generally T-shape when viewed from the X-axis direction.

[0084] The upper cover 30B includes: an upper cover body portion 31B, which is configured to cover the first zipper pull 50B and the second zipper pull 60B from above; an upper retaining groove portion 32B, which is configured for the first zipper pull 50B and the second zipper pull 60B; an engaging groove portion 35B, which is configured for the engaging portion 232B of the lower cover 20B; an engaging guide portion 36B, which guides the engaging portion 232B toward the engaging groove portion 35B; and an elastic sheet portion 37B, which is continuous with the engaging groove portion 35B. The upper surface 311B of the upper cover body portion 31B is formed of a flat surface.

[0085] The upper retaining groove 32B is formed on the surface of the upper cover body 31B opposite to the lower cover 20B, and is set to a groove shape corresponding to the upper plate portion 612 of the respective pull head body 61 of the first pull head 50B and the second pull head 60B.

[0086] like Figure 9 and Figure 10 As shown, the engaging groove 35B is located in the central portion of the upper cover body 31B in the X-axis direction, and is composed of a pair of upright pieces 351 that rise upward from one end of the upper cover body 31B and the elastic piece 37B, and an upper piece 352 that is continuous with the pair of upright pieces 351. The engaging groove 35B protrudes upward from the flat upper surface 311B of the upper cover body 31B and extends horizontally in the Y-axis direction.

[0087] like Figure 10 As shown, the engaging guide portion 36B is formed such that it protrudes in the Y-axis direction from the left and right inner surfaces 313B of the retaining groove portion 32B formed in the upper cover body portion 31B, and has a sliding guide surface 361, which is as follows: Figure 14 The image shows the engaging portion 232B of the lower cover 20B in the X-axis direction; the inclined guide surface 362, which is continuous with the sliding guide surface 361 and inclined upwards; and the engaging receiving surface 363, which is as shown in the image. Figure 13 As shown, it is continuous with the inclined guide surface 362 and receives the engaging portion 232B from below. The sliding guide surface 361 is disposed on the side of the first pull head 50B, and the engaging receiving surface 363 is disposed on the side of the second pull head 60B, and is disposed at a position higher than the sliding guide surface 361.

[0088] The elastic sheet portion 37B extends from the end portion of the upper cover body portion 31B near the first pull head 50B in the X-axis direction and is continuous with the upright sheet portion 351, so as to be able to be pushed up by the engaging portion 232B guided by the engaging guide portion 36B, and is configured to be elastically deformable in the Z-axis direction. Here, in the state where the pull head cover 10B is configured, the dimension in the Z-axis direction from the elastic sheet portion 37B to the sliding guide surface 361 is smaller than the thickness dimension of the engaging portion 232B. Therefore, when the upper cover 30B and the lower cover 20B are engaged as described later, the elastic sheet portion 37B... Figure 14 As shown, the engagement portion 232B, guided by the inclined guide surface 362, is pressed together and elastically deformed upwards. Figure 13 The engaging portion 232B shown is received by the engaging receiving surface 363, and the elastic piece portion 37B disengages from the engaging portion 232B and returns to its original state. In this way, the elastic piece portion 37B is elastically deformed, causing the upper cover 30B and the lower cover 20Bb to engage. Therefore, it is possible to suppress the increase in the thickness dimension of the pull head structure 1B in the Z-axis direction.

[0089] Furthermore, the upper surface of the elastic sheet portion 37B is formed flatly along the upper surface 311B. In addition, the elastic sheet portion 37B and the engaging groove portion 35B are disposed at the central position in the Y-axis direction of the upper cover 30B.

[0090] The pull-out cover 10B is constructed by engaging the engaging portion 232B of the lower cover 20B with the engaging groove portion 35B of the upper cover 30B. This engagement is performed as described below.

[0091] First, the upper cover 30B is positioned above the lower cover 20B, near the second pull head 60B in the X-axis direction. In the Z-axis direction, the upper cover 30B is brought close to the lower cover 20B, causing the engaging portion 232B to press against the elastic sheet portion 37B of the upper cover 30B. This causes the elastic sheet portion 37B to elastically deform upwards, placing the engaging portion 232B on the sliding guide surface 361 of the engaging guide portion 36B. Figure 14 The state shown.

[0092] Next, the upper cover 30B is moved relative to the lower cover 20B in the X-axis direction toward the first pull head 50B, guiding the engaging portion 232B along the sliding guide surface 361 and upwards obliquely using the inclined guide surface 362. Then, the engaging receiving surface 363 receives the lower surface of the engaging portion 232B from below. At this time, the elastic piece 37B disengages from the engaging portion 232B and returns to its original state, and the engaging portion 232B is positioned in the engaging groove 35B, becoming... Figure 13The engagement state is shown. In this engagement state, the front and rear surfaces of the engagement portion 232B along the Y-axis direction engage with a pair of upright pieces 351 in the X-axis direction, the left and right sides of the engagement portion 232B along the X-axis direction engage with the inner side surface 313B of the upper cover body portion 31B in the Y-axis direction, and the lower surface of the engagement portion 232B engages with the engagement receiving surface 363 in the Z-axis direction.

[0093] With the lower cover 20B and the upper cover 30B engaged, an operation connection portion 40B is formed between the lower cover 20B and the upper cover 30B, which connects to an operation member 5 such as an operation cord. This operation member 5 slides along a pair of zipper straps 2 in the X-axis direction to operate the zipper head structure 1B. In this embodiment, the operation connection portion 40B is composed of an engagement groove portion 35B and an engagement portion 232B.

[0094] The operation connection part 40B is located at the center of the X-axis direction opposite to the first pull head 50B and the second pull head 60B. In this embodiment, it is located at the center of the X-axis direction of the upper cover 30B.

[0095] The following describes the assembly sequence of the slider structure 1B.

[0096] First, prepare a pair of zipper pulls 50B and 60B with the zipper teeth 3 already inserted. The shoulder openings of the zipper pull bodies 61 are arranged opposite each other.

[0097] Next, the lower cover 20B is positioned below the first zipper head 50B and the second zipper head 60B, the lower plate portion 613 of each zipper head body 61 is respectively positioned in a pair of lower retaining groove portions 22B, and the engaging protrusion 23B passes through between each zipper head body 61.

[0098] Next, the upper cover 30B is positioned above the first pull head 50B and the second pull head 60B, and the upper plate portion 612 of the first pull head 50B and the second pull head 60B is positioned in the upper retaining groove portion 32B. As described above, the engaging groove portion 35B of the upper cover 30B is engaged with the engaging portion 232B of the lower cover 20B.

[0099] With the lower cover 20B and the upper cover 30B engaged, the zipper cover 10B is configured to cover the first zipper 50B and the second zipper 60B from above and below, and to cover the sides of the upper plate portion 612 of each of the first zipper 50B and the second zipper 60B. The first zipper 50B and the second zipper 60B are held in a relative position by a pair of lower retaining grooves 22B and upper retaining grooves 32B. The upper cover body portion 31B abuts against the upper plate portion 612 of the first zipper 50B and the second zipper 60B disposed in the upper retaining groove portion 32B. In addition, an operation connecting portion 40B is formed between the lower cover 20B and the upper cover 30B, and the operation member 5 is connected by passing through the operation connecting portion 40B.

[0100] The assembled zipper head structure 1B, as described above, is used in an adjustable zipper in which the teeth 3 of a pair of zipper tapes 2 are inserted into the first zipper head 50B and the second zipper head 60B, and the cord type 6 installed in the cord type mounting part 24B is connected to a specific part of clothing, etc., thereby adjusting the size of the specific part of clothing, etc., and tightening or loosening it.

[0101] If the operating element 5 is slidably moved in the X-axis direction within the adjustable zipper, the zipper head structure 1B slides along the pair of zipper straps 2. During this sliding movement, one of the first zipper head 50B and the second zipper head 60B disengages the pair of chain teeth 3 from each other, causing them to separate in the Y-axis direction, while the other zipper head 50B engages the pair of chain teeth 3 with each other. Therefore, even as the zipper head structure 1B slides, the portion of the pair of zipper straps 2 where the zipper head structure 1B is not located remains engaged. By sliding the zipper head structure 1B in this way, the size of a specific part of clothing or similar garment connected to a drawstring or strap 6 can be adjusted.

[0102] Furthermore, if the sliding operation of the operating component 5 ends, the sliding movement of the pull head structure 1B will stop and remain in its position.

[0103] [Variation Example]

[0104] In the first embodiment, the cord-like mounting portion 24 is formed at the end of the lower cover main body portion 21 on the side of the first pull head 50, but it may also be formed at the end of the lower cover main body portion 21 on the side of the second pull head 60. In the second embodiment, the cord-like mounting portion 24B is formed at the end of the lower cover main body portion 21B on the side of the second pull head 60B, but it may also be formed at the end of the lower cover main body portion 21B on the side of the first pull head 50B.

[0105] In the first and second embodiments, the lower surfaces 211 and 211B of the lower cover body portions 21 and 21B are formed from the same flat surface, but are not limited to this. As long as they are generally flat, they can also be formed from surfaces with various appearances.

[0106] In the first and second embodiments, the lower covers 20, 20B and the upper covers 30, 30B are made of synthetic resin, but they are not limited to this. As long as they can be interlocked with each other, they can also be made of various other materials such as metal.

[0107] In the first embodiment, the cord-like mounting portion 24 is formed at the end of the lower cover main body portion 21 on the side where the first pull head 50 is disposed in the X-axis direction, but it is not limited to this. It may also be formed at the end on the side opposite to the said end, or at both ends of the lower cover main body portion 21 in the X-axis direction. In addition, it may also be formed at both edges or one edge of the lower cover main body portion 21 in the Y-axis direction.

[0108] In the second embodiment, the cord-type mounting portion 24B is formed at the end of the lower cover main body portion 21B on the side where the second pull head 60B is disposed in the X-axis direction, but it is not limited to this. It may also be formed at the end on the side opposite to the said end, or at both ends of the lower cover main body portion 21B in the X-axis direction. In addition, it may also be formed at both edges or one edge of the lower cover main body portion 21B in the Y-axis direction.

[0109] [Effects]

[0110] The aforementioned zipper pull structures 1 and 1B cover the first zipper pulls 50 and 50B and the second zipper pulls 60 and 60B from both above and below. Therefore, the foreign body sensation caused by the first zipper pulls 50 and 50B and the second zipper pulls 60 and 60B directly touching the body can be eliminated on the back side of the clothing, and the appearance can be improved. Moreover, by forming the lower surfaces 211 and 211 of the lower covers 20 and 20B with flat surfaces, the foreign body sensation can be further reduced.

[0111] Furthermore, the operating connection parts 40 and 40B for connecting the operating member 5 are positioned at the center of the X-axis direction opposite to the first zipper pulls 50 and 50B and the second zipper pulls 60 and 60B. Therefore, when the operating member 5 is slidably operated, the zipper pull structures 1 and 1B can be prevented from tilting in the Z-axis direction (the back of the garment, etc.) relative to the X-axis direction, allowing the zipper pull structures 1 and 1B to slide stably and improving operability. In addition, the zipper pull covers 10 and 10B are composed of two components: lower covers 20 and 20B and upper covers 30 and 30B. Therefore, the number of parts can be reduced to decrease costs, and since there is no need to assemble more than two components, assemblability can be improved.
