Description

Technical Field

[0001] This invention relates to a zipper pull structure and zipper pull connector, which is used for adjusting the size of specific parts of clothing, such as around the abdomen or around the sleeves. Background Technology

[0002] Previously, double-zipper zippers for adjusting the degree of curling of a specific part of an article were known (see Patent Document 1). A double-zipper zipper includes: a first zipper and a second zipper for the teeth of two zipper straps to pass through; and an auxiliary connector for connecting the first zipper and the second zipper, the auxiliary connector being connected to a specific part of the article by a strap. The auxiliary connector includes: a connecting base (base component) that receives the first zipper and the second zipper from below; and a connecting cover (cover component) that engages with the connecting base and presses the first zipper and the second zipper from above. This double-zipper zipper slides due to the operation of the pull tab of the first zipper, causing a specific part of the article to curl.

[0005] Patent Document 1: Chinese Utility Model No. 209235120 Summary of the Invention

[0006] However, when operating the double-slip zipper described in Patent Document 1, there is a possibility that the first and second slippers may detach from the connecting base, and the connecting cover may detach accordingly. Therefore, it is desirable to maintain the holding position of the connecting base on the first and second slippers even in the above-mentioned situation.

[0007] The purpose of this invention is to provide a zipper head structure and a zipper head connector capable of maintaining the holding state of the first zipper head and the second zipper head.

[0008] The zipper pull structure of the present invention includes: a first zipper pull and a second zipper pull, which engage and disengage chain teeth arranged along a pair of straps; and a zipper pull connector that connects the first zipper pull and the second zipper pull facing each other, wherein the first zipper pull has a connecting portion formed in an upwardly projecting manner and having an upper surface and a side surface, and a pull tab capable of sliding along the pair of straps is connected to the connecting portion, the zipper pull connector including: a base member that holds the first zipper pull and the second zipper pull; and a cover member that engages with the base member and covers at least a portion of the first zipper pull and the second zipper pull from above, the base member including: a base base plate; a first pressing portion that stands upright from the base base plate and presses the first zipper pull from above; and a second pressing portion that stands upright from the base base plate and presses the second zipper pull from above.

[0009] According to the zipper pull structure of the present invention, the base component has a base plate portion and a first pressing portion and a second pressing portion, thereby reducing the possibility of the first zipper pull and the second zipper pull falling off when operating the zipper pull structure, and maintaining the holding state of the first zipper pull and the second zipper pull.

[0010] In the zipper pull structure of the present invention, the base component may have a first reinforcing portion, which is disposed adjacent to the first pressing portion in the direction along the base bottom plate portion and connects the base bottom plate portion and the first pressing portion.

[0011] With this structure, the base component has the aforementioned first reinforcing portion connecting the base plate portion and the first pressing portion, thus improving the connection strength between the base plate portion and the first pressing portion compared to the case without the first reinforcing portion. Therefore, even when a torque is applied to the slider connector when operating the slider structure, the possibility of the first pressing portion shifting relative to the first slider can be reduced, and the holding state of the first slider can be firmly maintained.

[0012] In the zipper pull structure of the present invention, the base component may have a second reinforcing portion, which is disposed adjacent to the second pressing portion in the direction along the base base plate portion and connects the base base plate portion and the second pressing portion.

[0013] With this structure, the base component has the aforementioned second reinforcing portion connecting the base plate portion and the second pressing portion. Therefore, compared to the case without the second reinforcing portion, the connection strength between the base plate portion and the second pressing portion can be improved. Consequently, even when a torque is applied to the slider connector when operating the slider structure, the possibility of the second pressing portion shifting relative to the second slider can be reduced, and the holding state of the second slider can be firmly maintained.

[0014] In the zipper pull structure of the present invention, the cover component may be configured to press at least a portion of the upper surface and a portion of the side surface of the connecting portion of the first zipper pull.

[0015] With this structure, even if an external force is applied to the connecting part of the first pull head due to, for example, twisting the pull tab, the cover member presses not only a part of the upper surface of the connecting part but also a part of the side surface, so the shaking between the first pull head and the cover member can be suppressed, and the possibility of the cover member deviating from the specified position relative to the first pull head can be reduced.

[0016] In the zipper pull structure of the present invention, the engagement position of the base component and the cover component in the vertical direction may be located at the same position as or lower than the pressing position of the first pressing part and the second pressing part pressing the first zipper pull and the second zipper pull from above.

[0017] With this structure, compared to the case where the engagement position of the base component and the cover component is positioned higher than the pressing position described above, it is possible to form a structure that makes it more difficult for foreign objects to get stuck in the engagement portion of the cover component and the base component, thereby reducing the possibility of the cover component and the base component disengaging from each other.

[0018] In the zipper pull structure of the present invention, the base component may have a pair of base side plates that rise upward from both sides of the base bottom plate, the first pressing part is disposed on one end of the base side plate, the second pressing part is disposed on the other end of the base side plate, and the engagement position of the base component and the cover component in the vertical direction is disposed at the same position as the upper edge of the base side plate or at a position lower than that position.

[0019] With this structure, the aforementioned engagement position is positioned in the vertical direction at the same position as or lower than the upper edge of the base side plate. This makes it more difficult for foreign objects to get stuck in the engagement part between the cover component and the base component, thus further reducing the possibility of the cover component and the base component disengaging from each other.

[0020] In the zipper pull structure of the present invention, the first pressing part and the second pressing part may each have a pressing surface that abuts against the first zipper pull and the second zipper pull from above, and the base component has a engaging surface that engages with the cover component in the vertical direction. The engaging surface is positioned at the same position as the pressing surface or at a position lower than that position.

[0021] With this structure, in the base component, the position (up and down position) of the engaging surface can be set relative to the position (up and down position) of the pressing surface as described above. This makes it easy to set the engaging position of the base component and the cover component in the up and down direction to the same position as the pressing position described above or to a position lower than that position.

[0022] In the zipper pull structure of the present invention, the cover component may have a cover engaging portion, which includes a pair of engaging claws facing each other in the left-right direction intersecting the vertical direction, and the base component may have a base engaging portion, which includes a pair of engaging surfaces in the left-right direction and a pair of guide surfaces, which are respectively located above each engaging surface. The engaging claws engage with the engaging surfaces in the vertical direction, and the pair of guide surfaces are configured to gradually widen in the left-right direction as they face downwards.

[0023] With this structure, the cover component is pressed against the base component from above, thereby gradually pushing a pair of engaging claws to the left and right while being guided along a pair of guide surfaces. The pair of engaging claws then move downwards past the pair of guide surfaces and return to their original position when engaging with the pair of engaging surfaces, thus enabling the pair of engaging claws to engage with the pair of engaging surfaces. In this way, the engaging portion of the cover and the engaging portion of the base can be smoothly engaged.

[0024] In the zipper pull structure of the present invention, the base engaging portion may have a pair of auxiliary guide surfaces, which are respectively arranged adjacent to the pair of guide surfaces on the second zipper pull side in the length direction intersecting the vertical and horizontal directions. The pair of auxiliary guide surfaces are configured to gradually widen towards each other in the horizontal direction as they approach the second zipper pull side.

[0025] With this structure, when the cover engagement part is pressed into the base engagement part, a pair of engagement claws can be guided towards a pair of guide surfaces in the longitudinal direction, so that the cover engagement part and the base engagement part can be smoothly engaged.

[0026] In the zipper pull structure of the present invention, the base engaging portion may also include an engaging post, which further has a limiting surface that restricts the movement of a pair of engaging claws toward the second zipper pull side in the engaging state.

[0027] With this structure, by engaging the cover engagement part with the base engagement part, the cover component can be restricted from moving toward the second zipper head side by the limiting surface. Therefore, there is no need for a structure to restrict this movement other than the engagement post, which simplifies the structure of the zipper head structure.

[0028] In the zipper pull structure of the present invention, the second zipper pull may have an upwardly protruding portion, and the cover component may cover the protruding portion.

[0029] With this structure, the cover member covers the protrusions such as the connecting part of the second zipper. Therefore, even if an external force is applied to the connecting part of the first zipper to make it wobble due to twisting the zipper, the wobble of the cover member can be more suppressed, and a structure can be formed in which the cover member is less likely to shift position relative to the first and second zippers.

[0030] In the zipper pull structure of the present invention, the first zipper pull may have a locking member installed on the connecting portion, and the locking tip that can engage with the chain teeth may protrude from the insertion path of the first zipper pull. The pull tab is configured to abut against the locking member by its pulling operation, and the locking tip that is protruding from the insertion path may become submerged in the insertion path.

[0031] Based on this structure, a so-called locking pull head can be formed, which causes the locking component to move by pulling the aforementioned pull tab.

[0032] In the zipper pull structure of the present invention, the base component may include: a first retaining portion having the first pressing portion and retaining the first zipper pull; a second retaining portion having the second pressing portion and retaining the second zipper pull; and a base engaging portion disposed between the first retaining portion and the second retaining portion. The cover component includes: a first cover portion covering and pressing at least a portion of the upper surface and a portion of the side surface of the connecting portion of the first zipper pull from above; a second cover portion covering at least a portion of the second zipper pull from above; and a cover engaging portion disposed between the first cover portion and the second cover portion and engaging with the base engaging portion.

[0033] The zipper pull connector of the present invention includes: a base component in the zipper pull structure of the present invention described above; and a cover component in the zipper pull structure of the present invention that engages with the base component.

[0034] According to the zipper pull structure of the present invention, a zipper pull connector can be formed that can achieve the same effect as the present invention described above.

[0035] Invention Effects

[0036] According to the present invention, a zipper pull structure and a zipper pull connector can be provided, which can reduce the possibility that the cover component may detach from the first zipper pull at a predetermined position. Attached Figure Description

[0047] (Structure of this embodiment)

[0048] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0049] exist Figures 1 to 4In this embodiment, the zipper pull structure 1 includes: a first zipper pull 10 (zipper pull) and a second zipper pull 20 (zipper pull), which are slidable to allow a chain of teeth (zipper chain teeth) consisting of spiral chain teeth arranged along a pair of belts (zipper belts) to engage and disengage with each other; and a zipper pull connector 30, which connects the first zipper pull 10 and the second zipper pull 20 to each other facing each other.

[0050] In the following description, the X direction is defined as the sliding direction (length direction) of the slider structure 1, the Y direction, which is orthogonal to the X direction, is defined as the left-right direction (width direction) of the slider structure 1, and the Z direction, which is orthogonal to the X and Y directions, is defined as the up-down direction (thickness direction) of the slider structure 1.

[0051] In this embodiment, the zipper pull structure 1 is used for an adjustable zipper to adjust the size of a garment, such as around the abdomen or sleeves. The adjustable zipper includes a pair of straps with the aforementioned chain teeth and the zipper pull structure 1. As an example of the use of the adjustable zipper, the straps are sewn into the garment, the chain teeth and the base member 40 of the zipper pull structure 1 (described later) are disposed on the inside of the garment, and the first zipper pull 10 and the second zipper pull 20 are engaged with the chain teeth on the inside of the garment in a slidable manner. The pull tab 18 and the cover member 60 of the zipper pull structure 1 (described later) are disposed on the outside of the garment, and the drawstring hole 411 (described later) is connected to a cord-like body for adjusting the size of specific parts of the garment, such as around the abdomen or sleeves.

[0052] like Figure 2 As shown, the first zipper head 10 includes: a zipper head body 11, which is capable of being inserted into each chain tooth row from the rear opening 10B to the shoulder opening 10A; and a pull tab 18, which allows the zipper head body 11 to slide along a pair of straps in the X direction.

[0053] The zipper head body 11 is integrally formed of the upper plate 12, the lower plate 13, the column portion 14 connecting the upper plate 12 and the lower plate 13, and the connecting portion 15 connecting the zipper pull 18, all made of the same material. A locking pin 16, which serves as a locking component, is installed on the connecting portion 15.

[0054] The lower plate portion 13 includes: a plate-shaped lower plate main body portion 131; and side plate portions 132, which respectively rise upward from the two side edges in the Y direction of the lower plate main body portion 131.

[0055] The column 14 extends upward from the shoulder opening 10A in the X direction of the lower plate main body 131 and is approximately at the center in the Y direction.

[0056] The upper plate portion 12 includes: a plate-shaped upper plate main body portion 121 formed on the upper part of the column portion 14; and a flange portion 122 extending from the side plate portions 132 on both sides in the Y direction toward the inward side in the Y direction. In this embodiment, the upper plate main body portion 121 and the flange portion 122 are formed separately from each other, and a belt passes between them.

[0057] The connecting portion 15 has a first connecting protrusion 151 and a second connecting protrusion 152 formed in an upwardly projecting manner from the upper plate main body portion 121. The first connecting protrusion 151 and the second connecting protrusion 152 are arranged at a distance from each other in the X direction, with the first connecting protrusion 151 disposed on the shoulder opening 10A side and the second connecting protrusion 152 disposed on the rear opening 10B side. The first connecting protrusion 151 has an upper surface 153 and a pair of left and right side surfaces 154 connected to the upper surface 153.

[0058] The locking pin 16 is arranged across the first connecting protrusion 151 and the second connecting protrusion 152. A hole (not shown) is formed in the upper plate main body 121 on the side of the second connecting protrusion 152. Opposite to this hole, an engaging tip (not shown) is provided that can move in and out of the insertion path 17 through which the chain teeth pass. This engaging tip engages with the chain teeth when protruding from the insertion path 17 (entering the aforementioned hole), and disengages when submerged in the insertion path 17 of the upper plate main body 121. In the engaged state, the zipper pull structure 1 cannot slide along the pair of belts; in the disengaged state, it can slide.

[0059] The pull tab 18 includes a pull tab body portion 181 and a pull tab shaft portion 183 formed at one end of the pull tab body portion 181. The pull tab shaft portion 183 is rotatably connected to the connecting portion 15. The pull tab shaft portion 183 is disposed between the first connecting protrusion 151 and the second connecting protrusion 152.

[0060] When a pulling force is applied to the pull tab body 181 during operation, the pull tab shaft 183 abuts against the locking pin 16 and undergoes elastic deformation, causing the engaging tip of the locking pin 16 to enter the hole in the upper plate 12, thus releasing the engagement between the engaging tip and the chain teeth. In the released state, the zipper pull structure 1 can slide along a pair of belts, and the size of the garment around the abdomen or sleeves can be adjusted by sliding the zipper pull structure 1.

[0061] Furthermore, when the operation ends and the aforementioned pulling force is no longer applied to the pull tab body 181, the locking pin 16, which caused the pull tab shaft 183 to elastically deform, returns to its original shape, and the engaging tip of the locking pin 16 protrudes from the hole in the upper plate 12 into the insertion path 17 and engages with the chain teeth. In the engaged state, the zipper pull structure 1 cannot slide along the pair of straps, and the dimensions around the abdomen or sleeves of the garment are fixed.

[0062] Thus, in this embodiment, the first zipper 10 is a so-called locking zipper that has a locking mechanism consisting of a locking pin 16, but it can also be a regular zipper that does not have a locking pin 16 to constitute a locking mechanism.

[0063] The second zipper pull 20 has a zipper pull body 21 that is formed in a substantially similar manner to the zipper pull body 11, except that it does not have a structure equivalent to the locking pin 16 and the pull tab 18, unlike the first zipper pull 10. Furthermore, the same reference numerals are appropriately used to indicate the same structures in the zipper pull body 21 as those in the zipper pull body 11, and detailed descriptions are omitted.

[0064] A connecting portion 25, which is an upwardly projecting protrusion, is formed on the upper surface of the upper plate main body 121 of the zipper pull body 21. The connecting portion 25 includes a pair of connecting protrusions 251 spaced apart in the X direction. In the zipper pull structure 1, the structure corresponding to the pull tab is not connected to the connecting portion 25. If the structure corresponding to the pull tab 18 is connected to the connecting portion 25 and the second zipper pull 20 is used as a zipper pull alone, the pair of connecting protrusions 251 are connected by riveting.

[0065] The shoulder openings 10A of the slider bodies 11 and 21 are arranged facing each other in the X direction, while the rear openings 10B are arranged at a position further away from each other in the X direction compared to the shoulder openings 10A. Therefore, when the chain teeth are inserted into the threaded path 17 from one of the rear openings 10B of the slider bodies 11 and 21, they are separated to the left and right in the Y direction due to the post 14, and the chain teeth delivered from the other rear opening 10B of the slider bodies 11 and 21 engage with each other.

[0066] The zipper connector 30 includes: a base member 40 that holds the first zipper 10 and the second zipper 20; and a cover member 60 that engages with the base member 40 and covers at least a portion of the first zipper 10 and the second zipper 20 from above.

[0067] Furthermore, while the first zipper pull 10 and the second zipper pull 20 are made of metal in this embodiment, they can also be formed of other materials such as synthetic resin.

[0068] The base component 40 includes: a base plate portion 41, one end of which has a cord hole 411 for a cord-like body (not shown) to pass through for connection; a base side plate portion 42, which rises upward from both sides of the base plate portion 41 along the X direction; left and right first pressing portions 43, which rise from the base plate portion 41, are disposed at one end of the base side plate portion 42 in the X direction, and press the first pull head 10 from above; left and right second pressing portions 44, which rise from the base plate portion 41, are disposed at the other end of the base side plate portion 42 in the X direction, and press the second pull head 20 from above; and a base engaging portion 51, which includes an engaging post 45A protruding upward from approximately the center of the base plate portion 41 in the X direction. Furthermore, the cord-like body passed through the cord hole 411 in this embodiment is used to adjust the size of the garment around the abdomen or sleeves, etc.

[0069] The base component 40 further includes: a first reinforcing portion 49, which is disposed adjacent to the first pressing portion 43 in the direction along the base plate portion 41 (along the in-plane direction in the X and Y directions) and connects the base plate portion 41 and the first pressing portion 43; and a second reinforcing portion 48, which is disposed adjacent to the second pressing portion 44 in the direction along the base plate portion 41 and connects the base plate portion 41 and the second pressing portion 44. The first reinforcing portion 49 and the second reinforcing portion 48 reinforce the first pressing portion 43 and the second pressing portion 44.

[0070] The first reinforcing part 49 is disposed adjacent to the first pressing part 43 at one end (the side with the rope hole 411) in the X direction of the base member 40. As the dimension of the first reinforcing part gradually increases from top to bottom in the X direction, the connection area with the base plate part 41 also increases, thus more firmly reinforcing the first pressing part 43. Furthermore, the first reinforcing part 49 and the base plate part 41 constitute a portion with a generally L-shaped cross-section.

[0071] The second reinforcing part 48 is disposed on the other end side in the X direction of the base member 40 and is formed as an end plate. The second reinforcing part 48, which rises from the base plate part 41, is disposed between and connected to the left and right second pressing parts 44, thereby more firmly reinforcing the second reinforcing part 48. In addition, the second reinforcing part 48 and the base plate part 41 form a portion with a generally L-shaped cross section.

[0072] The portion of the base component 40 at one end in the X direction from the base engaging portion 51 is configured as a first retaining portion 45 for retaining the first slider 10. Additionally, the portion of the base component 40 at the other end in the X direction from the base engaging portion 51 is configured as a second retaining portion 46 for retaining the second slider 20. The first retaining portion 45 has a first pressing portion 43, and the second retaining portion 46 has a second pressing portion 44. The base engaging portion 51 is disposed between the first retaining portion 45 and the second retaining portion 46.

[0073] In the first holding part 45, the lower plate main body part 131 and the side plate part 132 of the zipper head body 11 are covered by the base bottom plate part 41 and a pair of base side plate parts 42. The pressing surface 431, which is the lower surface of the first pressing part 43, abuts against and presses the rear opening 10B of the upper surface of the flange part 122, which is part of the upper plate part 12 of the zipper head body 11, from above.

[0074] In the second holding part 46, the lower plate main body part 131 and the side plate part 132 of the zipper body 21 are covered by the base bottom plate part 41 and a pair of base side plate parts 42. The pressing surface 441, which is the lower surface of the second pressing part 44, abuts against and presses the rear opening 10B of the upper surface of the flange part 122, which is part of the upper plate part 12 of the zipper body 21, from above.

[0075] like Figures 4 to 7 As shown, the base engaging portion 51 includes: a pair of left and right engaging surfaces 52 formed on the top end portion 451 of the engaging post 45A and on the side of the first retaining portion 45; a pair of left and right guide surfaces 53 disposed above the pair of left and right engaging surfaces 52; and a pair of left and right auxiliary guide surfaces 54 connected to the pair of left and right guide surfaces 53 and disposed on the side of the second retaining portion 46 relative to the pair of left and right guide surfaces 53. Additionally, the base engaging portion 51 also has a limiting surface 55 that restricts the movement of a pair of engaging claws 67 (described later) towards the second pull head 20 in the X direction, limiting the engagement state. The limiting surface 55 is formed by the surface on the side of the second retaining portion 46 in the engaging post 45A and is a surface along the Y and Z directions. This limiting surface 55 is disposed on the side of the second retaining portion 46 relative to the engaging surfaces 52.

[0076] A pair of left and right engaging surfaces 52 are formed by surfaces along the X and Y directions. The positions of the left and right engaging surfaces 52 are located at the same position as or lower than the Z-direction positions of the pressing surfaces 431 and 441. Therefore, the engaging position where the cover member 60 engages with the engaging surfaces 52 is the same position as or lower than the position where the first pressing part 43 and the second pressing part 44 press the upper plate portions 12 of the first pull head 10 and the second pull head 20, respectively. Furthermore, the Z-direction position of the engaging surfaces 52 (the aforementioned engaging position) is located at the same position as or lower than the portion of the upper edge of the base side plate portion 42 located on both sides of the engaging surfaces 52 in the Y direction. In this embodiment, the upper edge of the base side plate portion 42 is along the X direction, and the aforementioned engaging position is located at the same position as this upper edge in the Z direction.

[0077] The left and right pair of guide surfaces 53 are composed of inclined surfaces that gradually widen in the Y direction as they move downward from the top surface 452 of the locking post 45A. The left and right pair of auxiliary guide surfaces 54 are respectively arranged adjacent to the left and right pair of guide surfaces 53 on the side of the second slider 20 (side of the second retaining part 46), and are composed of inclined surfaces that gradually widen in the Y direction as they move downward from the left and right pair of guide surfaces 53 towards the side of the second slider 20. Furthermore, the left and right pair of auxiliary guide surfaces 54 are inclined obliquely upward from the side of the first slider 10 (side of the first retaining part 45) towards the side of the second slider 20 (side of the second retaining part 46).

[0078] The cover component 60 includes: a first cover portion 61 that covers and presses at least from above a portion of the upper surface 153 and a portion of a pair of side surfaces 154 in the connecting portion 15 of the first pull head 10; a second cover portion 62 that covers from above the connecting portion 25, which is at least a portion of the second pull head 20; and a cover engaging portion 63 that is disposed between the first cover portion 61 and the second cover portion 62 and engages with the base engaging portion 51.

[0079] Additionally, the cover component 60 includes: an upper portion 65 along the X direction; and a pair of left and right side portions 66 connected to the upper portion 65 along the X direction. The cover engaging portion 63 includes a pair of left and right engaging claws 67 extending downward from the pair of left and right side portions 66. Figure 4 As shown, in the engaging claw 67, the lower top claw portion 671 extends inward in the Y-axis direction, and the upper surface of the top claw portion 671 becomes the engaging surface 672. The engaging surface 672 engages with the engaging surface 52 of the base engaging portion 51 in the Z-direction. A guided surface 673 is formed on the top claw portion 671, which is inclined upwards towards the Y-direction. Because the guided surface 673 is inclined in this way, it can be smoothly guided by the guide surface 53 of the base engaging portion 51. Furthermore, since the engaging claw 67 engages with the limiting surface 55 on the side of the second pull head 20 in the X-direction, the movement of the cover member 60 to the other end in the X-direction is limited by the limiting surface 55. In addition, the movement of the cover member 60 to one end in the X-direction is limited by the connecting portion 25 of the second pull head 20.

[0080] The first cover portion 61 includes an upper portion 65 and a pair of side portions 66 located on the side of the first zipper pull 10 compared to the engaging claw 67, and the second cover portion 62 includes an upper portion 65 and a pair of side portions 66 located on the side of the second zipper pull 20 compared to the engaging claw 67. Therefore, in the engaged state where the cover engaging portion 63 engages with the base engaging portion 51, the upper portion 65 and the pair of side portions 66 constituting the first cover portion 61 are, for example, as shown in the image. Figure 3 As shown, at least a portion of the upper surface 153 and a pair of side surfaces 154 of the first connecting protrusion 151 covering the first zipper 10 constitutes the upper portion 65 and the pair of side surfaces 66 of the second cover portion 62 covering the connecting portion 25 of the second zipper 20.

[0081] In the above-described zipper pull structure 1, the steps for installing the cover component 60 onto the base component 40 are as follows.

[0082] First, such as Figure 8 As shown, the cover engagement portion 63 of the cover member 60 is pressed against the base engagement portion 51 of the base member 40 from above, and the connecting portion 25 of the second pull head 20 is covered by the second cover portion 62.

[0083] Next, the cover component 60 is pressed further downward, thereby causing the left and right pair of engaging claws 67 to be guided by the left and right pair of guide surfaces 53 of the base engaging part 51 and pushed outward in the Y direction. At this time, even if the engaging claws 67 engage with the left and right pair of auxiliary guide surfaces 54, the engaging claws 67 will be guided by the auxiliary guide surfaces 54 to the guide surface 53 side.

[0084] Next, the cover component 60 is pressed further downward, so that the pair of left and right engaging claws 67 pass over the pair of left and right guide surfaces 53, and the engaging surface 672 of the top claw 671 is positioned lower than the engaging surface 52 of the base engaging portion 51. Thus, the engaging claws 67 return to their original state, and the engaging surface 672 engages with the engaging surface 52 in the Z direction.

[0085] At this time, as described above, the engagement position of the cover engagement portion 63 and the base engagement portion 51 is the same as or lower than the pressing position in the Z direction where the first pressing portion 43 and the second pressing portion 44 press the first zipper pull 10 and the second zipper pull 20. Therefore, the zipper pull structure 1 can be configured such that, compared to the case where, for example, the engagement position is above the pressing position, foreign objects are less likely to get stuck in the cover engagement portion 63, thus reducing the possibility that the cover member 60 may detach from the base member 40 due to foreign objects being stuck there.

[0086] Furthermore, with the cover member 60 engaged with the base member 40, the first cover portion 61 covers and presses against the upper surface 153 and a portion of the pair of side surfaces 154 of the first connecting protrusion 151 of the first pull head 10. Therefore, even if an external force is applied to the connecting portion 15 of the first pull head 10 due to the twisting of the pull tab 18, since the cover member 60 presses against not only a portion of the upper surface 153 of the connecting portion 15 but also a portion of the pair of side surfaces 154, it is possible to suppress the shaking between the first pull head 10 and the cover member 60, thereby reducing the possibility of the cover member 60 deviating from the predetermined position relative to the first pull head 10.

[0087] (Modified Example)

[0088] In the above embodiment, the engagement position between the cover engagement portion 63 and the base engagement portion 51 is located at the same position or lower than the pressing position in the Z direction where the first pressing portion 43 and the second pressing portion 44 press the upper plate portion 12 of the first pull head 10 and the second pull head 20. However, if the cover member 60 is configured to be difficult to detach from the base member 40 due to foreign objects being trapped, it may also be located above the pressing position. In addition, the engagement position in the Z direction may also be located at the same position or lower than the position of the upper surface of the upper plate portion 12 of the first pull head 10 or the second pull head 20. In this case, it is more difficult for foreign objects to get stuck in the engagement portion, and a structure can be formed in which the engagement between the cover engagement portion 63 and the base engagement portion 51 is more difficult to detach.

[0089] In the above embodiment, the position of the engaging surface 52 in the Z direction (the engaging position mentioned above) is arranged at the same position as the upper edge of the base side plate portion 42 or at a position lower than that position. However, similarly, if the cover member 60 is configured to be difficult to detach from the base member 40 due to foreign objects being stuck, it may also be located above the upper edge of the base side plate portion 42.

[0090] In the above embodiment, the base engaging portion 51 includes a pair of guide surfaces 53 that gradually widen in the Y direction as they move downwards, and a pair of auxiliary guide surfaces 54 that gradually widen in the Y direction as they move towards the second pull head 20 side. This allows for smoother engagement with the cover engaging portion 63. However, the base engaging portion 51 may also omit the pair of guide surfaces 53 or the pair of auxiliary guide surfaces 54, as long as it is a structure capable of engaging with the cover engaging portion 63. Therefore, the structure of the pair of guide surfaces 53 or the pair of auxiliary guide surfaces 54 can be omitted. Furthermore, if the structure such as the pair of guide surfaces 53 is omitted, the structure of the guided surface 673 of the engaging claw 67 can be retained or omitted.

[0091] In the above embodiment, a connecting portion 25 is formed in the second pull head, but this structure may be omitted.

[0092] In the above embodiment, the cover member 60 adopts a structure that presses at least a portion of the upper surface 153 and a portion of a pair of side surfaces 154 of the connecting portion 15 of the first pull head 10, thereby reducing the possibility that, for example, the cover member 60 deviates from a predetermined position relative to the first pull head 10 when the pull tab 18 is twisted. However, if the main purpose is to reduce the cover member 60 from falling off the base member 40 due to foreign objects or the like, it is sufficient to arrange the engagement position of the cover engagement portion 63 and the base engagement portion 51 at the same position as or lower than the pressing position in the Z direction where the first pressing portion 43 and the second pressing portion 44 press the upper plate portion 12 of the first pull head 10 and the second pull head 20. Alternatively, the cover member 60 may not press the upper surface 153 or the side surfaces 154 of the connecting portion 15 of the first pull head 10.
