Abstract

The zipper pulls (1, 2) of the present invention include a zipper pull body (10, 70), a pull tab (40), and a cover (30, 90) capable of elastic deformation. The zipper pull body (10, 70) includes a front mounting post (21, 81) and a rear mounting post (22, 82) erected from the upper wing plate (20, 80). The cover (30, 90) engages with the front mounting post (21, 81) and the rear mounting post (22, 82). The front mounting post (21, 81) and the rear mounting post (22, 82) include: a pair of left and right first sidewall portions (21b, 22b, 81b, 82b); left... The right pair of second sidewall portions (21c, 22c, 81c, 82c) are positioned further outward in the length direction than the first sidewall portions (21b, 22b, 81b, 82b). The outer wall surface of the second sidewall portions (21c, 22c, 81c, 82c) is positioned inward in the width direction, separated from the outer wall surface of the first sidewall portions (21b, 22b, 81b, 82b) by the step portions (21g, 22g, 81g, 82g). At least a portion of the outer wall surface of the second sidewall portions (21c, 22c, 81c, 82c) is opposite to the inner wall surface of the cover (30, 90). Therefore, even if the cover (30, 90) is subjected to a force in the width direction of the pull head, it is more difficult for the cover (30, 90) to tip over in the width direction.

Description

Technical Field

[0001] This invention relates to a zipper pull for zippers. Background Technology

[0002] International Patent Publication No. 2009 / 133617 (Patent Document 1) discloses a puller with an automatic stop mechanism. For example, Figure 10 As shown, the zipper pull 100 described in Patent Document 1 is formed by a zipper pull main body 101, a pull tab 102, a spring component 103, and a cover 104. The zipper pull 100 is assembled by placing the pull tab 102 and the spring component 103 after the zipper pull main body 101, and then using the elastic deformation of the cover 104 to install the cover 104 onto the front and rear mounting posts 101a of the zipper pull main body 101. This type of zipper pull 100, assembled using the elastic deformation of the cover 104, allows for easy assembly and is also referred to as an embedded zipper pull.

[0005] Patent Document 1: International Publication No. 2009 / 133617 Summary of the Invention

[0006] Generally speaking, in a zipper pull, there may be a situation where the cover is pulled by the pull tab in the width direction. Therefore, the cover needs to be installed on the zipper pull main body in such a way that it will not tilt and detach from the front and rear mounting posts of the zipper pull main body even when subjected to such a force in the width direction.

[0007] For example, in the zipper pull 100 of Patent Document 1, the cover 104, which is mounted on the zipper pull main body 101, contacts the front and rear mounting posts 101a from the inside in the width direction. Therefore, even if subjected to a force in the width direction as described above, it is difficult for the cover 104 to tip over in the width direction, and it can prevent the cover 104 from detaching from the zipper pull main body 101. However, in order to make the zipper more stable for use in various products, it is required to more effectively prevent the cover from tipping over in the width direction.

[0008] The present invention was made in view of the above-mentioned problems, and its object is to provide a pull tab that makes it more difficult for the cover to tip over in the width direction, even when the cover is subjected to a force in the width direction of the pull tab.

[0009] To achieve the above objectives, the zipper pull provided by the present invention includes a zipper pull backbone forming a chain tooth guide path between an upper wing plate and a lower wing plate, a pull tab having a mounting shaft portion, and a cover capable of elastic deformation. The chain tooth guide path communicates with left and right shoulder openings at the front end and a rear opening at the rear end in the longitudinal direction of the zipper pull backbone. The zipper pull backbone has a front mounting post and a rear mounting post erected from the upper wing plate. The cover engages with the front and rear mounting posts by means of the elastic deformation of the cover. The assembly comprises: a pair of first sidewall portions on the left and right; and a pair of second sidewall portions on the left and right, which are arranged on the outer side in the length direction compared to the first sidewall portions. The outer wall surfaces of the second sidewall portions are arranged on the inner side in the width direction relative to the outer wall surfaces of the first sidewall portions on the left and right, separated by a step portion. The first sidewall portions on the left and right are exposed on the outer side. At least a portion of the second sidewall portions on the left and right are housed in the cover body. At least a portion of the outer wall surface of the second sidewall portion is opposite to the inner wall surface of the cover body.

[0010] In the zipper pull of the present invention, the cover preferably includes: a main body of the cover, which is arranged along the length direction; a front leg portion that extends in a manner that bends from the front end of the main body of the cover toward the zipper pull main body; and a rear leg portion that extends in a manner that bends from the rear end of the main body of the cover toward the zipper pull main body. The front leg portion and the rear leg portion of the cover are respectively engaged with the front mounting post and the rear mounting post of the zipper pull main body. The cover has a main body portion of the cover that extends from the front leg portion through the main body of the cover to the rear leg portion. At least the front leg portion and the rear leg portion have left and right side portions that extend from the left and right side edges of the main body portion toward the inner circumference of the main body portion of the cover.

[0011] In this case, it is preferable that the main body of the cover has left and right side portions extending from the left and right side edges of the main body of the cover toward the inner periphery of the main body of the cover. In the side view of the pull head, the lower end of the side portion of the main body of the cover is disposed facing the upper end of the first side wall portion of the front mounting post and the rear mounting post.

[0012] Furthermore, it is preferable that, when observing a cross section orthogonal to the width direction of the cover, the left and right side portions of the cover have the shortest possible distance between the inner peripheral edge of the cover body and the side portion in the curved portion where the cover body bends from the main body to the front or rear foot.

[0013] In the zipper pull of the present invention, preferably the front mounting post and the rear mounting post each have a locking claw portion that engages with the cover body. The locking claw portion protrudes outward in the longitudinal direction compared to the second side wall portion. The cover body has front and rear receiving holes for receiving the locking claw portion, and the front and rear receiving holes penetrate the cover body along the longitudinal direction.

[0014] In this case, the engaging claw portion of the front mounting post and the rear mounting post has a claw lower surface that contacts the cover body, and the claw lower surface has a curved surface that is arc-shaped when the cross section of the engaging claw portion is viewed orthogonal to the width direction.

[0015] Furthermore, in the zipper pull of the present invention, the zipper pull main body preferably includes: a front groove portion disposed from the front mounting post toward the front; and a rear groove portion disposed from the rear mounting post toward the rear.

[0016] Invention Effects

[0017] According to the zipper pull of the present invention, even if the cover is subjected to a force in the width direction of the zipper pull, the cover is more difficult to tilt in the width direction. Attached Figure Description

[0111] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, the present invention is not limited to the embodiments described below; various modifications can be made as long as the invention has a substantially the same structure and achieves the same effect.

[0112] (Example 1)

[0113] Figure 1 This is an exploded perspective view showing the disassembled state of the zipper pull involved in Embodiment 1. Figure 2 and Figure 3 These are the side view and cross-sectional view orthogonal to the width direction of the pull head involved in this embodiment 1.

[0114] Furthermore, in the following explanation, the front-back direction refers to the length direction or sliding direction of the zipper pull. Specifically, when the zipper pull is used with a zipper, the direction of movement for engaging the left and right zipper teeth is designated as forward (shoulder side direction), and the direction of movement for disengaging the zipper teeth (rear side direction) is designated as rearward. Additionally, the vertical direction refers to the height direction of the zipper pull, for example, a direction orthogonal to the flat upper surface of the upper flange in the zipper pull's main body. Specifically, the direction on one side of the zipper pull's main body where the cover (or pull tab) is mounted is designated as upward, and the opposite side as downward. Furthermore, the left-right direction refers to the width direction of the zipper pull, a direction orthogonal to both the length and height directions of the zipper pull.

[0115] The zipper pull 1 in this embodiment 1 is formed by five components: a puller main body 10, a pull tab 40, a stop claw body 50, a leaf spring component 60, and a cover body 30. The zipper pull 1 has an automatic stop mechanism formed by the stop claw body 50.

[0116] In Embodiment 1, the slider trunk 10, pull tab 40, stop claw body 50, and cover 30 are formed of a thermoplastic synthetic resin. The leaf spring component 60 is formed of metal. Furthermore, in this invention, the material of the slider is not particularly limited and can be varied. For example, at least some components of the slider trunk, pull tab, stop claw body, and cover can also be formed of metal.

[0117] The pull head main body 10 includes: an upper wing plate 20; a lower wing plate 11, which is arranged parallel to the upper wing plate 20; a connecting post 12, which connects the front end (shoulder end) of the upper wing plate 20 and the front end (shoulder end) of the lower wing plate 11; left and right upper flange portions 13, which are disposed on the left and right sides of the upper wing plate 20; and left and right lower flange portions 14, which are disposed on the left and right sides of the lower wing plate 11.

[0118] The pull tab main body 10 includes: a front mounting post (first mounting post) 21 and a rear mounting post (second mounting post) 22, which rise upwards from the upper wing plate 20; a front recess 23 located in front of the front mounting post 21; and a rear recess 24 located behind the rear mounting post 22. In this configuration, the front mounting post 21 and the rear mounting post 22 are arranged far apart from each other in the front-rear direction, and a gap is provided between the front mounting post 21 and the rear mounting post 22 for the insertion of the mounting shaft portion 43 of the pull tab 40 (described later).

[0119] At the front end of the zipper pull main body 10, left and right shoulder openings are formed such that the connecting post 12 is sandwiched in the middle. At the rear end of the zipper pull main body 10, a rear opening is formed. A generally Y-shaped zipper tooth guide path 15 connecting the left and right shoulder openings and the rear opening is formed between the upper wing plate 20 and the lower wing plate 11 of the zipper pull main body 10. Zipper tape insertion gaps for inserting zipper tapes (not shown) are provided on the left and right side edges of the zipper pull main body 10. In this case, the left and right zipper tape insertion gaps in the zipper pull main body 10 are formed between the left and right upper flange portions 13 and the left and right lower flange portions 14.

[0120] The front mounting post 21 of this embodiment 1 includes: a front base portion 21a, which is disposed at the center of the upper wing plate 20 in the width direction; a pair of left and right front first sidewall portions 21b; a pair of left and right front second sidewall portions 21c, which are disposed on the outer side (front) in the length direction than the front first sidewall portions 21b; a front engaging claw portion 21d, which protrudes forward from the front base portion 21a; a front protrusion portion 21e, which protrudes upward from the front base portion 21a; and a claw receiving recess 21f, which is provided at the rear end of the front base portion 21a.

[0121] The left and right front first side wall portions 21b of the front mounting column 21 are integrally provided with the front base portion 21a on the left and right sides of the front base portion 21a. Each of the left and right front first side wall portions 21b has an outer wall surface arranged orthogonally to the width direction of the pull head 1, and the left and right outer wall surfaces are formed into flat planes.

[0122] The outer wall surface of the first front sidewall portion 21b is not housed within the cover 30 mounted on the slider trunk 10, but is exposed on the outside. In this case, the outer wall surface of the first front sidewall portion 21b is arranged in the same or approximately the same position as the outer surface of the front leg portion 32 of the cover 30 (described later) in the width direction of the slider 1, so that it forms the same plane or is substantially the same plane as the outer surface of the front leg portion 32 of the cover 30 mounted on the slider trunk 1.

[0123] The upper end (top end) of the first sidewall portion 21b on the left and right front sides has an upper end surface (top end surface) arranged parallel to the upper surface of the upper wing plate 20. The upper end surface of the first sidewall portion 21b on the front side faces the lower end of the left and right side surface portions 35 of the main body 31 of the cover body 30, which will be described later. In particular, in the case of this embodiment 1, the upper end surface of the first sidewall portion 21b on the front side contacts the lower end of the left and right side surface portions 35 of the main body 31 of the cover body, thereby supporting the cover body portion 34 from below.

[0124] The left and right front second sidewall portions 21c of the front mounting post 21 are housed within the cover 30 mounted on the slider trunk 10. In this case, at least a portion of the front second sidewall portions 21c is housed within the front foot portion 32 of the cover 30, and is covered in a manner that prevents them from being seen from the outside. The left and right front second sidewall portions 21c extend forward from the front first sidewall portion 21b via the step portion 21g.

[0125] The left and right front second sidewall portions 21c protrude forward compared to the front end face of the front base portion 21a. Furthermore, the front second sidewall portions 21c have a front edge extending vertically. This allows a portion of the cover 30 (the cover body portion 34 of the front foot portion 32) to easily contact the left and right front second sidewall portions 21c, stabilizing the position of the cover 30 relative to the slider trunk 10 in the front-back direction. Additionally, it suppresses the cover 30 from wobbling in the front-back direction.

[0126] The outer wall surfaces of the left and right front second sidewall portions 21c are formed as flat surfaces orthogonal to the width direction. Furthermore, in this invention, the outer wall surfaces of the left and right front second sidewall portions 21c can also be arranged obliquely relative to the length direction of the slider 1. The outer wall surface of the front second sidewall portion 21c is arranged more inwardly in the width direction than the outer wall surface of the front first sidewall portion 21b, and the aforementioned stepped portion 21g is provided between the outer wall surfaces of the front first sidewall portion 21b and the front second sidewall portion 21c. Therefore, the interval between the outer wall surfaces of the left and right front second sidewall portions 21c is smaller than the interval between the outer wall surfaces of the left and right front first sidewall portions 21b. Additionally, in the case of this embodiment 1, the stepped portion 21g of the front mounting post 21 is inclined downwardly towards the front in the side view of the slider main body 10.

[0127] By providing the stepped portion 21g as described above, the outer wall surface of the second front sidewall portion 21c can be stably positioned inside the outer wall surface of the first front sidewall portion 21b in the width direction. Furthermore, when the cover 30 is installed on the zipper pull main body 10, the front leg 32 of the cover 30 can slide into contact with the stepped portion 21g of the front mounting post 21, guiding the front leg 32 towards a predetermined position. This allows the front leg 32 of the cover 30 to easily and smoothly engage with the front engaging claw portion 21d of the front mounting post 21. Therefore, the workability of assembling the zipper pull 1 can be improved.

[0128] Furthermore, the stepped portion 21g of the front mounting post 21 can absorb the thickness (width dimension) of the side portion 35 of the front leg portion 32 of the cover 30, as described later. This allows the outer wall surface of the first front side wall portion 21b and the outer side surface of the front leg portion 32 of the cover 30 to be positioned on the same plane without steps or on approximately the same plane with minimal steps, as described above. As a result, the zipper pull 1 achieves good aesthetics and improves its appearance. Additionally, the zipper pull 1 has a good feel, and it is less likely that fingers or other parts will get caught on it.

[0129] The flat outer wall surface of the left and right front second sidewall portion 21c has a portion that faces the left and right inner wall surfaces of the front foot portion 32 of the cover 30. In particular, in the case of this embodiment 1, the outer wall surface of the left and right front second sidewall portion 21c is arranged in such a way that it contacts or approaches the left and right inner wall surfaces of the front foot portion 32 of the cover 30 from the inside. In addition, by arranging the front second sidewall portion 21c inside the front foot portion 32 of the cover 30 in this way, it is possible to ensure that in the side view of the zipper pull 1 (refer to...) Figure 2 The area (area) in which the outer wall surface of the second sidewall portion 21c contacts or overlaps with the inner wall surface of the cover 30 is larger than, for example, the area in which the slider trunk 101 of the slider 100 in contact with the cover 104 as described in Patent Document 1. Therefore, as will be described later, the cover 30 is less likely to tip over in the width direction, improving the mounting strength of the cover 30 relative to the slider trunk 10.

[0130] The front engaging claw portion 21d of the front mounting post 21 is disposed in the width direction between the left and right front second side wall portions 21c, and for example as... Figure 2 As shown, it protrudes forward compared to the second sidewall portion 21c on the left and right front sides. When observing a cross-section orthogonal to the width direction of the front engaging claw portion 21d, the front engaging claw portion 21d includes: an upper claw surface; an inclined surface that slopes downward from the upper claw surface toward the top end of the front engaging claw portion 21d; and a lower claw surface 21h that is disposed from the top end of the front engaging claw portion 21d to the front end face of the front base portion 21a. In addition, the lower claw surface 21h of the front engaging claw portion 21d has a concave curved surface that is curved in an arc shape in a cross-section orthogonal to the width direction.

[0131] For example, when the cover 30 is lifted by operating the pull tab 40 and using the mounting shaft 43 of the pull tab 40, a part of the cover 30 (specifically, the cover body 34 of the front foot 32) comes into contact with the lower surface 21h of the front engaging claw 21d, and the lower surface 21h of the front engaging claw 21d is subjected to a load (stress) from the cover 30. At this time, since the lower surface 21h of the claw is provided with the curved surface as described above, the load applied to the front engaging claw 21d from the cover 30 can be easily dispersed, making it difficult for the load to concentrate in a local area of ​​the front engaging claw 21d. As a result, damage to the front engaging claw 21d or the front base 21a can be suppressed.

[0132] The front protrusion 21e of the front mounting post 21 protrudes upward from the front base portion 21a between the front engaging claw portion 21d and the claw receiving recess 21f in the front-rear direction. The front protrusion 21e is inserted into the mounting hole portion 61 provided in the leaf spring member 60 (described later), thereby determining the position of the front end of the leaf spring member 60 relative to the pull head main body 10.

[0133] The claw receiving recess 21f of the front mounting post 21 is formed downward from the upper surface of the front base portion 21a. The bottom part of the support shaft portion 52, which supports the stop claw body 50 (described later), is formed at the lower end of the claw receiving recess 21f. In addition, the claw receiving recess 21f is positioned to be sandwiched between the left and right front first sidewall portions 21b.

[0134] The rear mounting post 22 of this embodiment 1 includes: a rear base portion 22a, which is disposed at the center of the upper wing plate 20 in the width direction; a pair of left and right rear first sidewall portions 22b; a pair of left and right rear second sidewall portions 22c, which are disposed on the outer side (rear) in the length direction than the rear first sidewall portions 22b; a rear engaging claw portion 22d, which protrudes rearward from the rear base portion 22a; and a rear protrusion portion 22e, which protrudes upward from the rear base portion 22a. In addition, a claw hole 22f is provided in the rear base portion 22a, which penetrates the rear mounting post 22 and the upper wing plate 20 in the vertical direction and communicates with the chain tooth guide path 15.

[0135] In this embodiment 1, the rear first sidewall portion 22b, rear second sidewall portion 22c, rear engaging claw portion 22d, and rear protrusion 22e of the rear mounting post 22 are formed with their front-to-back orientations reversed relative to the corresponding front first sidewall portion 21b, front second sidewall portion 21c, front engaging claw portion 21d, and front protrusion 21e of the front mounting post 21, but are substantially the same as their counterparts in the front mounting post 21. The rear first sidewall portion 22b, rear second sidewall portion 22c, rear engaging claw portion 22d, and rear protrusion 22e will be briefly described below.

[0136] The left and right rear first sidewall portions 22b are integrally formed with the rear base portion 22a and have a flat outer wall surface arranged orthogonally to the width direction of the slider 1. The outer wall surface of the rear first sidewall portion 22b is exposed on the outside. In addition, the outer wall surface of the rear first sidewall portion 22b is arranged in the same or substantially the same position as the outer side surface of the rear foot portion 33 of the cover 30 which is mounted on the slider main body 10 in the width direction of the slider 1, thereby the outer wall surface of the rear first sidewall portion 22b and the outer side surface of the rear foot portion 33 of the cover 30 are arranged on the same plane or substantially the same plane.

[0137] The upper end (top end) of the left and right rear first sidewall portion 22b has an upper end surface (top end surface) arranged parallel to the upper surface of the upper wing plate 20. The upper end surface of the rear first sidewall portion 22b is opposite to the lower end of the left and right side surface portions 35 of the main body of the cover 31 in the cover body 30, and in particular, in the case of this embodiment 1, it contacts the lower end of the left and right side surface portions 35 of the main body of the cover 31.

[0138] The left and right rear second sidewall portions 22c are housed within the cover 30 mounted on the slider trunk 10. In this case, at least a portion of the rear second sidewall portions 22c is housed within the rear foot portion 33 of the cover 30, and is covered in a manner that prevents them from being seen from the outside. The left and right rear second sidewall portions 22c extend from the rear first sidewall portion 22b via the step portion 22g, and protrude rearward compared to the rear end face of the rear base portion 22a. The rear end edge of the rear second sidewall portion 22c runs vertically. Thus, the left and right rear second sidewall portions 22c, together with the left and right front second sidewall portions 21c, stabilize the position of the cover 30 relative to the slider trunk 10 in the front-rear direction, and suppress the swaying of the cover 30 in the front-rear direction.

[0139] The outer wall surface of the second rear side wall portion 22c is formed as a flat surface orthogonal to the width direction. Furthermore, the outer wall surface of the second rear side wall portion 22c can also be arranged in an inclined manner relative to the length direction of the slider 1. The outer wall surface of the second rear side wall portion 22c is positioned more inward in the width direction than the outer wall surface of the first rear side wall portion 22b. Additionally, the stepped portion 22g slopes downward in the rearward direction in the side view of the slider main body 10.

[0140] By providing a step portion 22g on the rear mounting post 22, when the cover 30 is installed on the slider trunk 10, the step portion 22g can guide the rear foot portion 33 of the cover 30, thus making it easy and smooth for the rear foot portion 33 of the cover 30 to engage with the rear engaging claw portion 22d of the rear mounting post 22. Furthermore, the step portion 22g can absorb the thickness of the side portion 35 in the rear foot portion 33 of the cover 30, thereby aligning the outer wall surface of the rear first side wall portion 22b and the outer side surface of the rear foot portion 33 of the cover 30 on the same plane or approximately the same plane, thus improving the appearance quality of the slider 1.

[0141] The outer wall surfaces of the left and right rear second sidewall portions 22c have portions that face the inner wall surfaces of the rear foot portions 33 of the cover 30. In particular, in the case of this embodiment 1, the outer wall surfaces of the left and right rear second sidewall portions 22c are arranged in a manner that contacts or approaches the inner wall surfaces of the rear foot portions 33 of the cover 30. Similar to the outer wall surfaces of the front second sidewall portions 21c described above, this ensures that in the side view of the slider 1 (refer to...),... Figure 2 The outer wall surface of the second rear side wall 22c contacts or overlaps with the inner wall surface of the cover 30 in a relatively large range.

[0142] The rear engaging claw portion 22d of the rear mounting post 22 protrudes rearward compared to the left and right rear second sidewall portions 22c. When viewing a cross-section orthogonal to the width direction, the rear engaging claw portion 22d includes: an upper claw surface; an inclined surface that slopes downward from the upper claw surface toward the top end of the rear engaging claw portion 22d; and a lower claw surface 22h that extends from the top end of the rear engaging claw portion 22d to the rear end face of the rear base portion 22a. Furthermore, the lower claw surface 22h of the rear engaging claw portion 22d has a concave curved surface that bends in an arc shape in a cross-section orthogonal to the width direction. This allows for easy distribution of the load applied to the rear engaging claw portion 22d from the cover 30, and helps to prevent damage to the rear engaging claw portion 22d or the rear base portion 22a.

[0143] The rear protrusion 22e protrudes upward from the rear base portion 22a in the front-rear direction between the rear engaging claw portion 22d and the claw hole 22f. The rear protrusion 22e is inserted into the mounting hole portion 61 of the leaf spring component 60, thereby determining the position of the rear end of the leaf spring component 60 relative to the pull head main body 10.

[0144] A front recess 23 is provided at the front end of the upper wing plate 20 to accommodate the lower front end of the cover 30, and a rear recess 24 is provided at the rear end of the upper wing plate 20 to accommodate the lower rear end of the cover 30. Because the front recess 23 and rear recess 24 are provided on the slider trunk 10, the overall height of the slider 1 from the lower surface of the lower wing plate 11 to the upper surface of the cover 30 can be easily reduced. Furthermore, a portion (thick body 34b) of the front leg 32 and rear leg 33 of the cover 30 (described later) can be easily inserted into the lower side of the front engaging claw 21d and rear engaging claw 22d of the slider trunk 10.

[0145] The pull tab 40 of this embodiment 1 includes: a pull tab main body 41 for gripping with fingers, etc.; left and right arm portions 42 extending from one end of the pull tab main body 41; and a mounting shaft portion (connecting portion) 43 connecting the top ends of the left and right arm portions 42. The cross-section of the mounting shaft portion 43 orthogonal to the axial direction is circular. A rectangular opening window portion is formed in the pull tab 40, which is surrounded by the pull tab main body 41, the left and right arm portions 42, and the mounting shaft portion 43. Furthermore, the shape, size, and material of the pull tab 40 are not particularly limited in this invention.

[0146] The stop claw body 50 of this embodiment 1 includes: a claw body portion 51, which is generally C-shaped or J-shaped in a side view of the stop claw body 50; a support shaft portion 52, which extends downward from the front end of the claw body portion 51; and a claw portion 53, which protrudes downward from the rear end of the claw body portion 51. The claw body portion 51 is arranged such that it at least extends over the upper side of the mounting shaft portion 43 of the pull tab 40 between the front mounting post 21 and the rear mounting post 22.

[0147] The stop claw 50 is mounted on the zipper pull trunk 10 in the following configuration: the support shaft 52 is received in the claw receiving recess 21f of the front mounting post 21, the top end of the support shaft 52 contacts the bottom surface of the claw receiving recess 21f, and the claw 53 is inserted into the claw hole 22f of the rear mounting post 22. Furthermore, the stop claw 50 is configured to swing or rotate with the contact point between the support shaft 52 and the bottom surface of the claw receiving recess 21f as a fulcrum. By swinging or rotating the stop claw 50, the claw 53 can enter or exit the chain tooth guide path 15 of the zipper pull trunk 10.

[0148] The leaf spring component 60 of this embodiment 1 is formed by punching a metal sheet of a predetermined shape from a continuous strip of metal such as stainless steel. Mounting holes 61 are formed at one end (front end) and the other end (rear end) of the leaf spring component 60, respectively, opening inwards from the front and rear edges of the leaf spring component 60. The leaf spring component 60 is mounted to the zipper pull 1 by being held between the front mounting post 21 and the rear mounting post 22 of the zipper pull trunk 10 and the cover body 34 of the cover 30. Furthermore, the leaf spring component 60 applies force to the stop pawl 50 in a direction that causes the pawl 53 to enter the chain tooth guide path 15 of the zipper pull trunk 10.

[0149] The cover 30 of this embodiment 1 includes: a main body 31 disposed along its length; a front leg 32 extending downwardly from the front end of the main body 31; and a rear leg 33 extending downwardly from the rear end of the main body 31, forming an inverted U-shape in the side view of the cover 30. The cover 30 is formed in a way that allows for elastic deformation. Furthermore, the cover 30 is fixed to the slider main body 10 by engaging the front leg 32 with the front mounting post 21 and the rear leg 33 with the rear mounting post 22.

[0150] The cover 30 includes: a main body (top) 34 extending from the front leg 32 via the main body 31 to the rear leg 33; and left and right side portions 35 extending from the left and right side edges of the main body 34 toward the inner periphery of the main body 34. The cover 30 is box-shaped, opening downwards and having a bottom surface on its upper side. Additionally, a space is provided inside the cover 30 to accommodate a portion of the stop claw 50 and the leaf spring member 60. In this case, the main body 34 forms a front surface portion of the front leg 32, an upper surface portion of the main body 31, and a rear surface portion of the rear leg 33. The left and right side portions 35 of the cover 30 are continuously provided throughout the front leg 32, the main body 31, and the rear leg 33.

[0151] like Figure 5 As shown, the inner peripheral edge of the left and right side portions 35 of the cover 30 includes: a lower edge 36, which is linearly disposed on the main body 31 of the cover along the front-rear direction; and an inclined edge 37, which is disposed on the front foot portion 32 and the rear foot portion 33, and is disposed inclined relative to the vertical direction. Furthermore, the lower edge 36 and the front and rear inclined edge 37 are continuously formed via an arc-shaped inner peripheral edge. The inclined edge 37 disposed on the front foot portion 32 and the rear foot portion 33 of the cover 30 is disposed facing the stepped portions 21g and 22g formed on the front mounting post 21 and the rear mounting post 22. In this case, the inclined edge 37 of the front foot portion 32 and the rear foot portion 33 is far away from the stepped portions 21g and 22g of the front mounting post 21 and the rear mounting post 22.

[0152] like Figure 5 As shown, the main body 34 of the main body 31 (i.e., the upper surface of the main body 31) has an inner surface (back side) that is concavely curved so that its central portion is furthest from the upper wing plate 20 in the longitudinal direction. Therefore, when the stop claw 50 is lifted against the force exerted by the leaf spring member 60, it is difficult for the leaf spring member 60 and the stop claw 50 to interfere with the main body 34 of the main body 31.

[0153] The left and right side portions 35, disposed on the main body 31 of the cover, extend downward from the main body 34 of the cover. Furthermore, the lower ends of the left and right side portions 35 have lower edge 36 arranged in a straight line along the front-rear direction as described above. The lower edge 36 of the left and right side portions 35 contacts four locations: the upper surfaces of the left and right front first sidewall portions 21b of the front mounting post 21 in the slider main body 10, and the upper surfaces of the left and right rear first sidewall portions 22b of the rear mounting post 22. Therefore, the cover 30 is supported by the slider main body 10 at these four locations, thereby enabling the slider 1 of this embodiment 1 to have high strength against loads applied from the upper side of the cover 30, as described later.

[0154] The front foot portion 32 and the rear foot portion 33 of the cover 30 each have a cover body portion 34 and left and right side portions 35, and the cross sections of the front foot portion 32 and the rear foot portion 33 orthogonal to the height direction are approximately U-shaped.

[0155] The left and right side portions 35 of the front foot portion 32 of the cover 30 are disposed on the outer side of the front second side wall portion 21c of the front mounting post 21, covering the outer wall surface of the front second side wall portion 21c. The left and right side portions 35 of the rear foot portion 33 of the cover 30 are disposed on the outer side of the rear second side wall portion 22c of the rear mounting post 22, covering the outer wall surface of the rear second side wall portion 22c.

[0156] In this configuration, the left and right side portions 35 of the front foot portion 32 and the rear foot portion 33 are arranged to contact or approach the outer wall surface of the front second side wall portion 21c of the front mounting post 21 or the outer wall surface of the rear second side wall portion 22c of the rear mounting post 22. By arranging the front foot portion 32, the rear foot portion 33, and the cover 30 in this manner, it is possible to ensure that the area in which the outer wall surface of the front second side wall portion 21c contacts or overlaps with the inner wall surface of the cover 30, as described above, is large.

[0157] In the cover body 30 of this embodiment 1, a front and rear insertion recess 38 is provided in the cover body part (upper surface part) 34 of the cover main body 31. The front and rear insertion recess 38 is for the front protrusion 21e of the pull head main body 10 provided on the front side mounting post 21 and the rear protrusion 22e of the rear side mounting post 22 to be inserted.

[0158] Furthermore, receiving holes 39 are provided on the front leg 32 and rear leg 33 of the cover 30. These receiving holes 39 respectively receive the front engaging claw 21d of the zipper pull stem 10 located on the front mounting post 21 and the rear engaging claw 22d of the zipper pull stem 10 in an insertable manner. The front engaging claw 21d and the rear engaging claw 22d of the zipper pull stem 10 are received in these receiving holes 39 on the front leg 32 and the rear leg 33, thereby the cover 30 is installed on the zipper pull stem 10 in a snap-fit ​​manner.

[0159] In this embodiment 1, the receiving hole 39 provided in the cover 30 extends linearly through the cover 30 along its length. As a result, the mold used to form the cover 30 can be formed with a relatively simple structure, thus reducing the manufacturing cost of the slider 1.

[0160] Furthermore, the cover body portion (front part) 34 of the front leg portion 32 and the cover body portion (rear part) 34 of the rear leg portion 33 include: a thin body portion 34a, which is provided at the lower end of the front leg portion 32 or the rear leg portion 33; a thick body portion 34b, which is provided adjacent to the receiving hole portion 39, and the thickness (dimensional in the front-rear direction) of the cover body portion 34 is greater than that of the thin body portion 34a; and a gradually increasing portion 34c, which gradually increases the thickness of the cover body portion 34 from the thin body portion 34a toward the thick body portion 34b. By providing the thin body portion 34a at the lower end of the front leg portion 32 and the rear leg portion 33, the cover 30 can be easily placed on the front mounting post 21 and the rear mounting post 22 of the zipper head 10 during assembly. In addition, by providing the thick body portion 34b adjacent to the receiving hole portion 39 on the front leg portion 32 and the rear leg portion 33, the engagement strength of the cover 30 with respect to the zipper head 10 can be improved.

[0161] In the cover 30 of this embodiment 1, for example, Figure 5 As shown, when observing a cross-section orthogonal to the width direction of the cover 30, the left and right side portions 35 have the shortest allowable variation in the curved portion where they bend from the main body 31 to the front leg 32 or rear leg 33, extending from the main body 34 to the inner peripheral edge of the side portion 35. Thus, by providing a short allowable variation in the curved portion of the cover 30, the distance X between the side portion 35 and the main body 34 is minimized, allowing the cover 30 to easily elastically deform in a way that opens the front leg 32 and rear leg 33 in a direction away from each other. Consequently, when the cover 30 is placed on and engaged with the front mounting post 21 and rear mounting post 22 of the slider main body 10, the cover 30 can easily elastically deform, facilitating assembly with the slider main body 10. Furthermore, the left and right side portions 35 of the cover 30 are less prone to damage during elastic deformation.

[0162] Next, the method of manufacturing the slider 1 of this embodiment 1 by assembling the five components described above: slider main body 10, slider 40, stop claw body 50, leaf spring component 60, and cover body 30 will be described.

[0163] First, place the pull tab 40 on the upper flange 20 of the pull head main body 10. At this time, insert the mounting shaft 43 of the pull tab 40 between the front mounting post 21 and the rear mounting post 22 of the pull head main body 10, and insert the front mounting post 21 or the rear mounting post 22 into the opening window of the pull tab 40.

[0164] Next, the stop claw body 50 and the leaf spring component 60 are sequentially placed on the slider trunk 10 on which the pull tab 40 is mounted. With the stop claw body 50 placed on the slider trunk 10, the support portion 52 of the stop claw body 50 is inserted into the claw receiving recess 21f provided on the front mounting post 21 of the slider trunk 10, and the claw portion 53 of the stop claw body 50 is inserted into the claw hole 22f provided on the rear mounting post 22 of the slider trunk 10. Next, the leaf spring component 60 is placed on the front mounting post 21 and the rear mounting post 22 such that the front protrusion 21e and the rear protrusion 22e of the slider trunk 10 are inserted into the front and rear mounting holes 61 of the leaf spring component 60.

[0165] Then, the cover 30 is installed on the pull head main body 10, which houses the pull tab 40, the stop claw 50, and the leaf spring component 60. At this time, the cover main body 31 of the cover 30 is brought close to the pull head main body 10 in a forward or backward tilted position, and the front engaging claw 21d (or the rear engaging claw 22d) of the pull head main body 10 is inserted into the receiving hole 39 provided in the front leg 32 (or the rear leg 33) of the cover 30.

[0166] Next, the rear leg 33 (or front leg 32) of the cover 30 is pushed downward along the front-back direction by tilting the main cover 31. As a result, the cover 30 elastically deforms by opening the front leg 32 and rear leg 33 outward in the longitudinal direction, causing the rear leg 33 (or front leg 32) of the cover 30 to descend. At this time, the rear leg 33 (or front leg 32) of the cover 30 can be guided and lowered using the step 21g (or step 22g) provided on the rear mounting post 22 (or front mounting post 21) of the slider main 10, thus preventing the cover 30 from deviating from its position relative to the slider main 10 (especially in the width direction), allowing for a smooth and stable assembly of the cover 30.

[0167] Furthermore, as the rear leg 33 (or front leg 32) of the cover 30 descends, the receiving hole 39 provided on the rear leg 33 (or front leg 32) of the cover 30 reaches the position of the rear engaging claw 22d (or front engaging claw 21d) of the slider trunk 10, thereby the cover 30 elastically recovers, and the rear engaging claw 22d (or front engaging claw 21d) of the slider trunk 10 is inserted into the receiving hole 39 provided on the rear leg 33 (or front leg 32) of the cover 30.

[0168] Thus, the cover 30 is installed in a manner that engages with the front mounting post 21 and the rear mounting post 22 of the slider trunk 10, thereby manufacturing the slider 1 of this embodiment 1. The assembly operation of the slider 1, which utilizes the elastic deformation of the cover 30 as described above, can be easily and stably performed by manual operation or by using automatic assembly equipment.

[0169] In the zipper pull 1 of this embodiment 1 manufactured as described above, when the pull tab 40 is in a free state (non-operation state) and not being operated, the stop claw 50 is forced by the leaf spring member 60, causing the claw 53 to enter the chain tooth guide path 15 of the zipper pull main body 10. In the zipper pull 1 of this embodiment 1, an automatic stopping mechanism formed by the stop claw 50 is provided in this way.

[0170] Furthermore, in the swivel head 1 of this embodiment 1, as described above, the inner wall surfaces of the front foot portion 32 and the rear foot portion 33 of the cover 30 are arranged to contact or approach the outer wall surfaces of the left and right front second side wall portions 21c and the left and right rear second side wall portions 22c provided on the swivel head main body 10. This ensures that in the side view of the swivel head 1, the area in contact with or overlapping with the front second side wall portion 21c and the rear second side wall portion 22c of the inner wall surface of the cover 30 is large.

[0171] Therefore, even if the cover 30 is subjected to a load (stress) in the direction that causes it to tip over in the width direction, such as from the pull tab 40, the inner wall surface of the cover 30 is in contact with the outer wall surfaces of the front second side wall portion 21c and the rear second side wall portion 22c, thus easily blocking the load in the tipping direction. Therefore, the cover 30 is difficult to tip over in the width direction, and as a result, the installation strength of the cover 30 relative to the pull tab main body 10 can be improved.

[0172] Furthermore, in the slider 1 of this embodiment, as described above, the left and right side portions 35 of the main body 31 of the cover 30 extend in the vertical direction. The lower edge 36 of the left and right side portions 35 contacts four locations: the upper surfaces of the left and right front first sidewall portions 21b of the front mounting post 21 and the upper surfaces of the left and right rear first sidewall portions 22b of the rear mounting post 22 in the slider main body 10. The cover 30 is supported at these four locations. Therefore, when, for example, the cover 30 is pressed down from above, causing a downward load (stress) to be applied to the cover 30, the downward load can be stably supported by the four contact portions between the cover 30 and the front first sidewall portion 21b and the rear first sidewall portion 22b. Additionally, the left and right side portions 35 of the main body 31 can also be provided to prevent the main body 31 from deforming downwards. Therefore, the pull head 1 of this embodiment 1 can exhibit higher strength relative to the load (impact load) applied from the upper side of the cover 30.

[0173] (Example 2)

[0174] Figure 6 and Figure 7 This is a perspective view and a side view of the zipper puller involved in this embodiment 2. Figure 8 and Figure 9 These are top and side views showing the main body of the zipper pull according to Embodiment 2. Furthermore, in Figures 6-9 The illustration of the pull-out sheet is omitted in the text.

[0175] The zipper pull 2 ​​involved in this embodiment 2 does not have an automatic stopping mechanism formed by the stop claw body 50 like the zipper pull 1 of the aforementioned embodiment 1, and is formed as a so-called free zipper pull 2.

[0176] In this embodiment 2, the zipper pull 2 ​​is formed from three components: a zipper pull body 70, a pull tab (not shown), and a cover 90. Furthermore, as an example of the pull tab in this embodiment 2, the pull tab 40 described in the aforementioned embodiment 1 can be used.

[0177] The zipper pull main body 70 of this embodiment 2 includes: an upper wing plate 80; a lower wing plate 71; a connecting post 72 that connects the front ends of the upper wing plate 80 and the front ends of the lower wing plate 71; and left and right upper flange portions 73, which are disposed on the left and right sides of the upper wing plate 80. In addition, the zipper pull main body 70 includes: a front mounting post 81 and a rear mounting post 82, which stand upright from the upper wing plate 80; a front groove portion 83, which is disposed in front of the front mounting post 81; and a rear groove portion 84, which is disposed behind the rear mounting post 82.

[0178] The front mounting post 81 of this embodiment 2 includes: a front base portion 81a, which is disposed at the center of the upper wing plate 80 in the width direction; a pair of left and right front first sidewall portions 81b; a pair of left and right front second sidewall portions 81c, which are disposed forward of the front first sidewall portions 81b; and a front engaging claw portion 81d, which protrudes forward from the front base portion 81a. The front first sidewall portions 81b, front second sidewall portions 81c and front engaging claw portions 81d of this embodiment 2 are formed substantially the same as the front mounting post 21 of the aforementioned embodiment 1.

[0179] Specifically, in this embodiment 2, the left and right front first sidewall portions 81b have flat outer wall surfaces orthogonal to the width direction of the pull head 2, and the outer wall surfaces of the front first sidewall portions 81b are exposed on the outside. Furthermore, the upper end of the front first sidewall portion 81b has an upper end surface arranged parallel to the upper surface of the upper wing plate 80, and the upper end surface of the front first sidewall portion 81b contacts the lower ends (lower edge 96) of the left and right sidewall portions 95 of the main body of the cover 91. Thus, the cover 90 is supported from below.

[0180] The left and right front second sidewall portions 81c of the front mounting post 81 extend forward from the front first sidewall portion 81b via the step portion 81g. The outer wall surface of the front second sidewall portion 81c is formed as a flat surface orthogonal to the width direction, and is disposed inside the width direction than the outer wall surface of the front first sidewall portion 81b, separated by the step portion 81g. The step portion 81g is provided between the front first sidewall portion 81b and the front second sidewall portion 81c, thus improving the workability of the assembly operation of the zipper head 2 in the same way as the zipper head 1 of the aforementioned embodiment 1.

[0181] The flat outer wall surface of the second sidewall portion 81c on the left and right front sides is arranged to contact or approach the inner wall surface of the front foot portion 92 of the cover 90, which ensures that the area in which the outer wall surface of the second sidewall portion 81c contacts or overlaps with the inner wall surface of the cover 90 is large in the side view of the zipper pull 2. Therefore, similar to the zipper pull 1 of Embodiment 1 described above, the cover 90 is less likely to tip over in the width direction, and the installation strength of the cover 90 relative to the zipper pull main body 70 is improved.

[0182] When observing the cross-section orthogonal to the width direction of the front engaging claw portion 81d, the front engaging claw portion 81d of this embodiment 2 includes: an upper claw surface; an inclined surface that slopes downward from the upper claw surface toward the top end of the front engaging claw portion 81d; and a lower claw surface 81h that is disposed from the top end of the front engaging claw portion 81d to the front end face of the front base portion 81a. The lower claw surface 81h of the front engaging claw portion 81d has a concave curved surface that is curved in an arc shape in the cross-section orthogonal to the width direction. Thus, similar to the pull head 1 of the aforementioned embodiment 1, the load applied to the front engaging claw portion 81d from the cover 90 can be easily distributed, and damage to the front engaging claw portion 81d or the front base portion 81a can be suppressed.

[0183] The rear mounting post 82 of this embodiment 2 includes: a rear base portion 82a, which is disposed at the center of the upper wing plate 80 in the width direction; a pair of left and right rear first side wall portions 82b; a pair of left and right rear second side wall portions 82c, which are disposed on the outer side (rear) in the length direction than the rear first side wall portions 82b; and a rear engaging claw portion 82d, which protrudes rearward from the rear base portion 82a.

[0184] Although the rear first sidewall portion 82b, rear second sidewall portion 82c, and rear engaging claw portion 82d in the rear mounting post 82 of Embodiment 2 are formed with their front-to-back orientations reversed relative to the corresponding front first sidewall portion 81b, front second sidewall portion 81c, and front engaging claw portion 81d in the front mounting post 81, they are formed in essentially the same way as the corresponding portions of the front mounting post 81.

[0185] That is, the left and right rearward second sidewall portions 82c of the rear mounting post 82 extend rearward from the rearward first sidewall portion 82b via the step portion 82g. The outer wall surface of the rearward second sidewall portion 82c is formed as a flat surface orthogonal to the width direction, and is disposed inside the width direction than the outer wall surface of the rearward first sidewall portion 82b, across the step portion 82g. The outer wall surfaces of the left and right rearward second sidewall portions 82c are disposed in contact with or close to the inner wall surface of the rear foot portion 93 of the cover 90. The rearward engaging claw portion 82d has a claw lower surface 82h disposed from the top end of the rearward engaging claw portion 82d to the rear end face of the rearward base portion 82a.

[0186] A front groove 83 capable of accommodating the lower front end of the cover 90 is provided at the front end of the upper wing plate 80, and a rear groove 84 capable of accommodating the lower rear end of the cover 90 is provided at the rear end of the upper wing plate 80.

[0187] The cover 90 of this embodiment 2 includes: a main body 91; a front leg 92 that extends downwardly from the front end of the main body 91; and a rear leg 93 that extends downwardly from the rear end of the main body 91. The cover 90 is formed in a way that allows it to be elastically deformable.

[0188] The cover 90 includes: a main body 94 extending from a front leg 92 via a main body 91 to a rear leg 93; and left and right side portions 95 extending from the left and right side edges of the main body 94 toward the inner periphery of the main body 94. The main body 94 forms a front surface portion of the front leg 92, an upper surface portion of the main body 91, and a rear surface portion of the rear leg 93. The left and right side portions 95 in the cover 90 are continuously provided throughout the front leg 92, the main body 91, and the rear leg 93.

[0189] The inner peripheral edge of the left and right side portions 95 of the cover 90 includes: a lower edge 96 disposed on the main body 91 of the cover; and an inclined edge disposed on the front foot portion 92 and the rear foot portion 93, and is arranged inclined relative to the vertical direction.

[0190] The lower edge 96 of the side portion 95 of the cover body 91 contacts four parts: the upper ends (upper surfaces) of the left and right front first side wall portions 81b of the front mounting post 81 and the upper ends (upper surfaces) of the left and right rear first side wall portions 82b of the rear mounting post 82. The cover body 90 is supported by the pull head main body 70 at these four parts. Therefore, the pull head 2 of this embodiment 2 can have high strength against loads applied from the upper side of the cover body 90.

[0191] The left and right side portions 95 of the front foot portion 92 of the cover 90 are arranged to contact or approach the outer wall surface of the front second side wall portion 81c of the front mounting post 81. The left and right side portions 95 of the rear foot portion 93 of the cover 90 are arranged to contact or approach the outer wall surface of the rear second side wall portion 82c of the rear mounting post 82. As a result, it is ensured that the area in contact or overlapping between the outer wall surfaces of the front second side wall portion 81c and the rear second side wall portion 82c and the inner wall surface of the cover 90 is large, thus making it difficult for the cover 90 to tip over in the width direction.

[0192] Furthermore, receiving holes 99 are provided on the front leg 92 and rear leg 93 of the cover 90. These receiving holes 99 respectively accommodate the front engaging claw 81d of the slider trunk 70 located on the front mounting post 81 and the rear engaging claw 82d of the slider trunk 70 located on the rear mounting post 82. The receiving holes 99 extend linearly through the cover 90 along its length. The front engaging claw 81d and the rear engaging claw 82d of the slider trunk 70 are accommodated in the receiving holes 99 of the front leg 92 and the rear leg 93 of the cover 90, thereby the cover 90 is installed on the slider trunk 70 in a snap-fit ​​manner.

[0193] The free pull head 2 of this embodiment 2, as described above, similarly to the pull head 1 of the aforementioned embodiment 1, can improve the installation strength of the cover 90 relative to the pull head trunk 70, and can exhibit higher strength relative to the load applied from the upper side of the cover 90.

[0194] Furthermore, when the cover 90 is installed on the zipper head 70, the stepped portions 81g and 82g of the front mounting post 81 and / or rear mounting post 82 provided on the zipper head 70 can guide the front foot 92 and / or rear foot 93 of the cover 90. Therefore, it is possible to prevent the cover 90 from shifting in position (especially in the width direction) relative to the zipper head 70, and the assembly operation of the cover 90 can be carried out smoothly and stably.

[0195] Furthermore, the zipper pull 1 of Embodiment 1 is mainly used for zippers with synthetic resin zipper teeth formed by injection molding. Additionally, the zipper pull 2 ​​of Embodiment 2 is mainly used for zippers with spiral zipper teeth. However, the zipper pull of the present invention can also be applied to zippers with various forms of zipper teeth, such as synthetic resin zipper teeth formed by injection molding, spiral zipper teeth, or metal zipper teeth.
