Description

Technical Field

[0001] This utility model relates to a zipper pull and a zipper having the zipper pull. Background Technology

[0002] Japanese Patent Application Publication No. 9-294612 (Patent Document 1) discloses a zipper pull having a stopping mechanism based on a stopping member (claw bar). The stopping mechanism of the zipper pull is constructed to maintain the zipper pull, which is stopped relative to the chain teeth, in a position that does not move from its stopped position after a sliding operation of the zipper pull is performed (hereinafter, such a function is referred to as the stopping function).

[0003] In the zipper stop mechanism described in Patent Document 1, for example, when a finger leaves the zipper tab after a sliding operation based on the zipper tab, the claw of the stop member, generated by the elastic force of the elastically deformable portion of the stop member, engages with the zipper teeth by entering the zipper tooth guide path of the zipper body. By engaging the claw of the stop member with the zipper teeth, the zipper can be held in a stopped position relative to the zipper tooth row.

[0004] Furthermore, Patent Document 1 describes the following: when the zipper head is formed by four parts, such as the zipper head body, the zipper tab, the stop part, and the cover, all four parts can be formed of synthetic resin.

[0007] Patent Document 1: Japanese Patent Application Publication No. 9-294612 Summary of the Invention

[0008] In conventional zipper pulls equipped with a stop mechanism based on a stop component, the stop function is achieved by inserting the claw of the stop component into the gap between two adjacent zipper teeth and engaging with at least one of these zipper teeth.

[0009] On the other hand, depending on the stopping position of the zipper pull relative to the zipper teeth, sometimes the claw of the stopping component abuts against the zipper teeth from above without inserting into the gap between two zipper teeth, and is held in a state of contact with the upper surface of the zipper teeth. In this case, the elastically deformed part of the stopping component that generates elastic force cannot fully recover its elasticity and is held in a shape with large elastic deformation.

[0010] However, if left in the position where the claw is engaged with the zipper teeth as described above for an extended period, creep may occur due to the continuous application of load to the elastically deformed portion of the stop component, causing deformation of the elastically deformed portion. In stop components where the elastically deformed portion has deformed due to creep, it will not return to its original shape even if the load applied to the elastically deformed portion is removed, thus reducing the elastic force generated in the stop component. As a result, the force with which the claw of the stop component engages with the zipper teeth weakens, leading to a decrease in the strength (hereinafter referred to as locking strength) that holds the zipper pull in the stop position without movement.

[0011] This invention was made in view of the above-mentioned problems, and its purpose is to provide a zipper pull that is difficult to deform due to creep even when placed for a long time with the claw of the stop part in contact with the zipper teeth, and which can stably ensure appropriate locking strength, and a zipper having the zipper pull.

[0012] To achieve the above objectives, the zipper pull of this invention comprises: a zipper pull body having a tooth guide formed between an upper wing plate and a lower wing plate; a stop member having a rotating shaft portion rotatably held in the zipper pull body; a cover covering at least a portion of the stop member and mounted on the zipper pull body; and a pull tab having a mounting shaft portion held between the zipper pull body and the cover. In this zipper pull, the zipper pull body has a mounting wall portion extending upward from the upper wing plate, and the stop member has: a head supporting the rotating shaft portion; a neck extending from the head; a base portion connected to the top end portion of the neck; at least one claw portion protruding downward from the bottom surface of the base portion; and an elastic extension portion extending from the upper end portion of the head and capable of elastic deformation. The mounting wall portion has an insertion recess for inserting and holding the rotating shaft portion of the stop member, the insertion recess being formed such that the rotating shaft portion can move vertically within the insertion recess.

[0013] In the zipper pull of this utility model, preferably, the stop member moves upward within the insertion recess via the rotating shaft to increase the elastic deformation of the elastic extension, and moves downward within the insertion recess via the rotating shaft to decrease the elastic deformation of the elastic extension.

[0014] Additionally, preferably, the insertion recess has: a recessed bottom surface that supports the rotating shaft from the lower side when viewed from the side in a side view of the slider body viewed from the width direction of the slider; and a pair of guide inner wall surfaces that are continuously formed from the bottom surface of the recess toward the upper side and extend parallel to each other, the bottom surface of the recess being formed by a semi-circular or approximately arc-shaped portion that, in the side view, causes the size of the space portion within the insertion recess to gradually increase toward the upper side in a direction orthogonal to the vertical direction, and the spacing between the pair of guide inner wall surfaces has a constant size greater than or equal to the diameter of the rotating shaft.

[0015] Furthermore, preferably, the insertion recess is formed such that the rotating shaft portion can move in the vertical direction with a length that is more than 25% and less than 100% of the diameter of the rotating shaft portion.

[0016] Alternatively, preferably, the cover has a box-shaped shape with an opening at the lower end of the cover, and the cover has an inner protrusion that protrudes downward from the top plate portion of the cover within the cover, the inner protrusion being configured to contact or be close to the upper side of the mounting wall portion from the top side in such a way as to cover the insertion recess from the top side.

[0017] In this case, it is preferable that the maximum value of the vertical dimension of the space formed between the elastic extension and the neck in the stop member when the elastic extension is not elastically deformed is greater than the minimum value of the interval between the rotating shaft portion and the inner protrusion when the rotating shaft portion of the stop member contacts the bottom surface of the recess of the insertion recess.

[0018] According to the present invention, a connector is provided in which the above-mentioned zipper head is slidably mounted on a zipper tooth row provided on a pair of zipper teeth.

[0019] In the zipper of this invention, it is preferred that the zipper teeth forming the chain teeth have an inclined surface that is inclined relative to the height direction of the zipper head in such a way that when the claw of the stop member is in contact with the zipper teeth, and the zipper head is subjected to a force in a direction that moves in a manner that separates the left and right chains of the zipper teeth, the inclined surface presses against the claw and causes the rotating shaft to move upward within the insertion recess.

[0020] Utility Model Effect

[0021] According to the present invention, even if the zipper pull of the stop part is placed in contact with the zipper teeth for a long time, it is difficult for the stop part to be deformed by creep, thus ensuring appropriate locking strength. Attached Figure Description

[0090] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0091] Figure 1 This is an exploded perspective view schematically showing the disassembled state of the zipper head 1 in this embodiment. Figure 2 It is a schematic cross-sectional view showing the pull head body 10, the stop component 50 and the cover 70. Figure 3 This is a cross-sectional view of the zipper pull 1 schematically showing the state in which the claw 55 of the stop part 50 is engaged with the zipper teeth 5.

[0092] In addition, Figure 2 and Figure 3 The cross-section shown is a section cut out of the slider 1 at a position outside the slider width direction of the mounting wall 26 described later in the slider body 10. For the front end of the cover 70, in order to easily understand the positional relationship between the mounting wall 26 of the slider body 10 and the inner protrusion 73 described later in the cover 70, a cross-section is shown where the slider 1 is cut out at a position slightly inside the slider width direction of the outer wall surface of the mounting wall 26.

[0093] In the following description of the zipper pull 1, the front-back direction refers to the length direction of the zipper pull (or the length direction of the cover 70), and the other is the direction along the sliding direction of the zipper pull 1. In particular, in a zipper, the direction in which the zipper pull 1 moves to engage the left and right chains of teeth is defined as the front (shoulder side direction), and the direction in which the zipper pull 1 moves to disengage the chains of teeth is defined as the rear (rear side direction).

[0094] The vertical direction refers to the height direction of the swivel head, for example, the direction orthogonal to the upper wing plate 11 and lower wing plate 12 of the swivel head body 10. In this case, the direction relative to the mounting cover 70 (or pull tab 40) of the swivel head body 10 is set as upward, and the opposite direction is set as downward.

[0095] The left and right directions are the width direction of the slider, which is orthogonal to the length and height directions of the slider.

[0096] The zipper pull 1 of this embodiment is used for a zipper with a left and right pair of zipper teeth connected together, wherein a plurality of zipper teeth 5 are provided on the zipper tape. In this case, each zipper tooth 5 is formed on the side edge of the zipper tape by injection molding of synthetic resin. On the side edge of each left and right zipper tape, a tooth row formed by a plurality of zipper teeth 5 is provided along the tape length direction.

[0097] Each zipper tooth 5 has an independent shape that separates from the adjacent zipper teeth 5 in the front-to-back direction. Each zipper tooth 5, without detailed illustration, has: a tooth body portion 6 fixed to the zipper tape; a tooth neck portion extending from the tooth body portion 6 in the width direction of the zipper tape and having a constricted shape; a generally elongated oval-shaped engaging head extending further from the tooth neck portion in the width direction of the tape; a pair of shoulders extending from the tooth neck portion in the length direction of the tape; and a tooth groove portion recessed at the top of the engaging head portion.

[0098] In each zipper tooth 5, at one end and the other end (i.e., the front end and the rear end) of the tooth body portion 6 in the front-back direction, there is an inclined surface 6a that is inclined so that the size of the zipper tooth 5 in the front-back direction gradually decreases from the center portion of the zipper tooth 5 in the vertical direction toward the upper side and toward the lower side.

[0099] In this embodiment, by providing an inclined surface 6a on the upper half of the front end of the zipper tooth 5, as described later, when the claw 55 of the stop member 50 is in contact with the front end of the zipper tooth 5, and the zipper pull 1 is subjected to a force in the rearward direction, the inclined surface 6a of the zipper tooth 5 can be used to press the claw 55. Figure 3 and Figure 4 Additionally, the stop member 50 can be rotated by pressing, and the rotating shaft portion 52 of the stop member 50 (described later) can be moved upward within the insertion recess 26a.

[0100] In this embodiment, the zipper pull 1 is slidably mounted to the zipper teeth and the chain teeth on the left and right sides. The zipper pull 1 has a stop mechanism (automatic stop mechanism), which automatically performs a stop function based on the stop member 50 when, for example, the user removes their finger from the zipper tab 40 after sliding the zipper pull 1.

[0101] The zipper pull 1 is formed by four components: a zipper pull body 10, a pull tab 40, a stop component 50, and a cover 70. All four components are made of thermoplastic synthetic resin. The zipper pull body 10, pull tab 40, stop component 50, and cover 70 can be manufactured by injection molding of synthetic resin. Furthermore, in this invention, the material of the zipper pull 1 is not limited; for example, at least one of the zipper pull body 10, pull tab 40, stop component 50, and cover 70 can also be made of metal.

[0102] The zipper head body 10 has: an upper wing plate 11; a lower wing plate 12 arranged parallel or substantially parallel to the upper wing plate 11; a connecting post 13 connecting the front end (shoulder end) of the upper wing plate 11 and the front end (shoulder end) of the lower wing plate 12; left and right upper flanges 14 provided at the left and right side edges of the upper wing plate 11; and left and right lower flanges 15 provided at the left and right side edges of the lower wing plate 12.

[0103] At the front end of the zipper pull body 10, a connecting post 13 is sandwiched in the middle to form left and right shoulder openings. A rear opening is formed at the rear end of the zipper pull body 10. Between the upper wing plate 11 and the lower wing plate 12 in the zipper pull body 10, a roughly Y-shaped tooth guide path 16 is formed, connecting the left and right shoulder openings and the rear opening. The left and right zipper teeth and their associated tooth rows are inserted into the tooth guide path 16.

[0104] The left and right side edges of the zipper head body 10 are provided with zipper tape insertion gaps for the zipper tape to pass through. The left and right zipper tape insertion gaps are formed between the upper flange 14 and the lower flange 15 of the zipper head body 10, and are also connected to the zipper tooth guide 16.

[0105] The swiper head body 10 includes: a front mounting post 21 extending upward from the front end of the upper wing plate 11; a rear mounting post 22 extending upward from the rear end of the upper wing plate 11; a pair of left and right mounting wall portions 26 extending rearward from the front mounting post 21; and a pull tab guide portion 27 disposed between the mounting wall portion 26 and the rear mounting post 22 in a side view of the swiper head body 10. The front mounting post 21, the rear mounting post 22, the mounting wall portion 26, and the pull tab guide portion 27 are integrally provided on the upper wing plate 11.

[0106] The zipper body 10 is provided with a receiving recess 28 formed by recessing from the upper surface of the upper wing plate 11 between the left and right mounting wall portions 26, a claw hole 31 penetrating the upper wing plate 11 in the vertical direction, and a base mounting portion 32 of the base 54, which is described later, in which the stop member 50 is mounted.

[0107] The front mounting post 21 and rear mounting post 22 of the slider body 10 each have a support post portion 23 extending upward from the upper wing plate 11 and an engaging claw portion 24 provided at the upper end of the support post portion 23. On the left and right sides of the upper ends of the front mounting post 21 and the rear mounting post 22, a layer difference portion 25 is provided along the front-rear direction.

[0108] The layer difference portions 25 of the front mounting post 21 and the rear mounting post 22 are formed such that the portion of the front mounting post 21 or the rear mounting post 22 located above the layer difference portion 25 is smaller in the width direction than the portion located below the layer difference portion 25. When the cover 70 is installed on the slider body 10, the inner protrusion 73, which will be described later, located inside the cover 70, contacts the layer difference portion 25 of the front mounting post 21 and the rear mounting post 22 from above or is positioned close to the layer difference portion 25 from above.

[0109] The engaging claw portion 24 of the front mounting post 21 protrudes forward from the support post portion 23. Furthermore, in a side view of the slider body 10, it is formed into a triangular shape with a downwardly sloping surface facing forward and a lower end face parallel to the front-rear direction. The engaging claw portion 24 of the rear mounting post 22 protrudes rearward from the support post portion 23. Furthermore, in a side view of the slider body 10, it is formed into a triangular shape with a downwardly sloping surface facing rearward and a lower end face parallel to the front-rear direction.

[0110] Each of the left and right mounting wall portions 26 extends upward in a thin plate shape from the upper surface of the upper wing plate 11. Each mounting wall portion 26 is arranged in a front-rear direction from the support column portion 23 of the front mounting column 21. A gap is provided between the left and right mounting wall portions 26, into which the head 51 (described later) of the stop member 50 can be inserted.

[0111] The left and right mounting wall portions 26 each have: an upper surface portion parallel to the upper surface of the upper wing plate 11; an inclined portion sloping downwards towards the rear; and an insertion recess 26a formed in a manner that recesses downwards from the upper surface portion of the mounting wall portion 26. The insertion recess 26a has: an opening in the upper surface portion of the mounting wall portion 26; and a space extending from the opening in a vertical direction to an inner portion near the upper surface of the upper wing plate 11. Furthermore, the space of the insertion recess 26a may also extend from the opening to the upper surface of the upper wing plate 11.

[0112] The left and right rotating shafts 52 of the stop component 50 are respectively inserted from the top into the recesses 26a of the left and right mounting wall portions 26. The recesses 26a hold the inserted rotating shafts 52 in a rotatable manner within the inner space, and also hold the rotating shafts 52 in a manner that allows them to move in the vertical direction. (See side view of the slider body 10 viewed from the left and right directions, for example, refer to...) Figure 2 The insertion recess 26a has: a recess bottom surface 26b that supports the rotating shaft portion 52 inserted into the insertion recess 26a from the lower side; and a pair of front and rear guide inner wall surfaces 26c that are connected to the recess bottom surface 26b and formed along the vertical direction.

[0113] The bottom surface 26b of the insertion recess 26a, viewed from the side of the slider body 10, is formed only by a semi-circular arc-shaped curved portion whose size gradually increases upwards in the front-rear direction of the space within the insertion recess 26a. In this case, the bottom surface 26b of the recess is formed into an arc-shaped shape with a diameter the same as or slightly larger than the diameter of the rotation shaft portion 52 of the stop member 50. Alternatively, the bottom surface 26b of the recess may also be formed by a generally arc-shaped curved portion that has a near-semi-circular arc shape in the aforementioned side view.

[0114] In a side view of the slider body 10, a pair of guide inner wall surfaces 26c of the insertion recess 26a extend continuously upward from both ends of the arc-shaped bottom surface 26b of the recess and are arranged parallel to each other. Therefore, in the area above the semi-circular bottom surface 26b of the recess, the insertion recess 26a does not have a portion that narrows the gap (the front-back dimension of the space) between the front and rear guide inner wall surfaces 26c, and is formed such that the gap between the front and rear guide inner wall surfaces 26c is a constant size.

[0115] In this case, the gap between the front and rear guide inner wall surfaces 26c is set to be the same size as the diameter of the rotating shaft portion 52 of the stop member 50 or slightly larger than the diameter of the rotating shaft portion 52. In addition, the gap between the front and rear guide inner wall surfaces 26c is preferably 150% or less, more preferably 125% or less, of the diameter of the rotating shaft portion 52 of the stop member 50.

[0116] In a side view of the slider body 10, the maximum value of the vertical dimension from the bottom surface 26b of the insertion recess 26a to the upper surface of the mounting wall 26 is set to 125% to 200% of the diameter of the rotation shaft portion 52 of the stop member 50, preferably 140% to 180%. Therefore, when the rotation shaft portion 52 of the stop member 50 is inserted into and accommodated in the insertion recess 26a, the rotation shaft portion 52 of the stop member 50 can move vertically within the insertion recess 26a by, for example, a length (distance) of 25% to 100% of the diameter of the rotation shaft portion 52. As a result, the elastic deformation of the elastic extension portion 58 of the stop member 50 can be easily increased or decreased, as described later.

[0117] The upper surface of the mounting wall portion 26 is set at the same height as the layer difference surface (upper surface) of the layer difference portion 25 provided on the front mounting post 21. When the cover 70 is installed on the slider body 10, the inner protrusion 73 of the cover 70 contacts or is positioned close to the upper surface of the mounting wall portion 26 from above. As a result, the insertion recess 26a of the mounting wall portion 26 is blocked or covered from above by the inner protrusion 73 of the cover 70, thus preventing the rotation shaft portion 52 of the stop member 50 inserted into the insertion recess 26a of the mounting wall portion 26 from dislodging from the insertion recess 26a.

[0118] The pull tab guide 27 is disposed between the mounting wall 26 and the rear mounting post 22 in the front-to-back direction. Furthermore, for example, in a top view of the pull tab body 10 (not shown), the pull tab guide 27 is disposed adjacent to the claw hole 31 in front of it. The pull tab guide 27 is disposed at a position moving rearward from the mounting wall 26, and also at a position moving forward from the rear mounting post 22.

[0119] The pull tab guide 27 has a forward-sloping downward-inclined guide surface 27a, a rear end face that faces rearward and is continuous with the inner wall surface of the claw hole 31, and left and right triangular side faces. The pull tab guide 27 is arranged along the left and right direction with a constant shape in its cross-section orthogonal to the left and right direction. The left and right dimensions of the pull tab guide 27 are set to be larger than the interval between the left and right mounting wall portions 26 and smaller than the left and right dimensions of the claw hole 31.

[0120] By providing such a pull tab guide 27 and a downwardly inclined portion of the mounting wall 26 facing rearward on the upper wing plate 11, for example, when the pull tab 40 is tilted at an angle parallel to the upper wing plate 11, the mounting shaft portion 43 of the pull tab 40 (described later) can be easily moved to a position between the mounting wall 26 and the pull tab guide 27 by the guide inclined surface 27a of the pull tab guide 27 and the inclined portion of the mounting wall 26.

[0121] The receiving recess 28 of the slider body 10 has a shape that is recessed downward relative to the upper surface of the upper wing plate 11. The receiving recess 28 is provided rearward from the position of the rear wall surface of the front mounting post 21. The receiving recess 28 is formed to have a constant cross-sectional shape (or constant space) from the mounting wall portion 26 on the left side to the mounting wall portion 26 on the right side. The bottom surface of the receiving recess 28 is positioned upward relative to the lower surface of the upper wing plate 11 (facing the inner wall surface of the chain guide 16) in the vertical direction.

[0122] When the pull head 1 is assembled, a portion of the head 51 of the stop member 50 (described later) is inserted into the receiving recess 28. The receiving recess 28 is formed to a depth and size such that even if the rotation shaft portion 52 of the stop member 50 moves up and down within the insertion recess 26a of the mounting wall portion 26, the head 51 of the stop member 50 will not contact the bottom surface of the receiving recess 28.

[0123] The claw hole 31 extends vertically from the upper surface of the upper wing plate 11 to the chain tooth guide 16. For example, in a top view of the zipper head body 10, the claw hole 31 has a shape that allows the stop member 50 (especially the base 54 of the stop member 50, which will be described later) to be inserted. For example, in this embodiment, the claw hole 31 is formed into a quadrilateral shape in a top view of the zipper head body 10. The claw hole 31 is provided in the center of the upper wing plate 11 in the left-right direction, and in the front-back direction between the left and right mounting wall portions 26 and the rear mounting post 22.

[0124] A base mounting portion 32 for mounting the base 54 of the stop member 50 is provided within the claw hole 31. The base mounting portion 32 is located at the center of the claw hole 31 in the left-right direction along the front-back direction, and mounts and supports the portion between the two claw portions 55 of the base 54 of the stop member 50. For example… Figure 2 As shown, the base mounting portion 32 is disposed at the lower end of the claw hole 31, and a layer difference is formed between the upper surface of the base mounting portion 32 and the upper surface of the upper wing plate 11. The lower surface of the base mounting portion 32 is formed continuously from the lower surface of the upper wing plate 11 without forming a layer difference.

[0125] The base mounting portion 32, by supporting the base 54 of the stop member 50 within the claw hole 31, can limit the depth to which the two claws 55 of the stop member 50 enter the zipper tooth guide 16. This allows the claws 55 of the stop member 50 to properly engage with the zipper teeth 5. Furthermore, in the case of a zipper with, for example, a release insert comprising a push bar, a seat bar, and a socket, when the push bar is inserted into the zipper tooth guide 16 of the zipper head body 10, it is possible to prevent the push bar from hooking onto the claws 55 and to stably insert it into the socket.

[0126] The pull tab 40 has a pull tab body 41 that is held by the user's fingers, left and right arms 42 extending from one end of the pull tab body 41, and a mounting shaft 43 connecting the top ends of the left and right arms 42. The cross-section of the mounting shaft 43 orthogonal to the axial direction has a circular or nearly circular shape. A rectangular opening window is formed in the pull tab 40, surrounded by the pull tab body 41, the left and right arms 42, and the mounting shaft 43. The mounting shaft 43 of the pull tab 40 is held between the pull head body 10 and the cover 70. Furthermore, in this utility model, the shape, size, and material of the pull tab 40 are not particularly limited.

[0127] The stop component 50 is formed by injection molding of synthetic resin, and the stop component 50 is integrally formed. The stop component 50 is formed of elastic synthetic resin. Furthermore, in this invention, the material of the stop component 50 is not particularly limited.

[0128] The stop member 50 has: a head 51 inserted between the left and right mounting wall portions 26 of the slider body 10; left and right rotating shaft portions 52 protruding outward from the head 51 in the left and right directions; a neck 53 extending rearward from the head 51; a base 54 connected to the rear end of the neck 53; two claw portions 55 protruding downward from the bottom surface of the base 54; and an elastic extension portion 58 extending from the upper end of the head 51 and capable of elastic deformation. Except for the two claw portions 55, the stop member 50 has a shape that is symmetrical about the center position in the left and right directions.

[0129] The head 51 of the stop member 50 has: a plate-shaped head body 51a with a constant left-right dimension (width); and a lower head end 51b that protrudes downward from the head body 51a and has a left-right dimension smaller than that of the head body 51a. For example, when the rotation shaft 52 of the stop member 50 is inserted into the insertion recess 26a of the mounting wall 26 and held therein, Figure 2 As shown, a portion of the head body 51a and the lower end portion 51b are received in the receiving recess 28 of the pull head body 10. The left and right sides of the head body 51a are formed as planes orthogonal to the left and right directions. The width of the head body 51a is set to be smaller than the interval between the left and right mounting wall portions 26.

[0130] The left and right rotating shaft portions 52 are each formed into a cylindrical shape and are connected to the front end of the head body portion 51a. The diameter of the cylindrical rotating shaft portion 52 is set to be the same size as or slightly smaller than the distance between the front and rear guide inner wall surfaces 26c of the insertion recess 26a, so that the rotating shaft portion 52 can be inserted into the insertion recess 26a of the mounting wall portion 26.

[0131] The rotation shaft 52 of the stop member 50 is held in the insertion recess 26a of the slider body 10 in a vertical direction. In this case, the stop member 50 moves upward within the insertion recess 26a of the slider body 10 via the rotation shaft 52, thereby increasing the elastic deformation of the elastic extension 58 in the stop member 50. Conversely, the stop member 50 moves downward within the insertion recess 26a via the rotation shaft 52, thereby decreasing the elastic deformation of the elastic extension 58 in the stop member 50.

[0132] The neck 53 of the stop component 50 in a side view of the stop component 50 (e.g., see reference). Figure 2 It has a shape that extends rearward from the head body 51a and curves downward. The neck 53 has a front half 53a connected to the head body 51a and a rear half 53b connected to the base 54.

[0133] The front half of the neck 53a is formed such that, through a layer difference, the left-right dimension (the distance between the left and right sides) of the front half of the neck 53a is larger than that of the head body 51a. In this case, the left-right dimension of the front half of the neck 53a is set to be larger than the distance between the left and right mounting wall portions 26 in the pull head body 10, and smaller than the left-right dimension of the claw hole 31.

[0134] The lateral dimension of the posterior neck portion 53b is made smaller than that of the anterior neck portion 53a by means of layering. In this case, the lateral dimension of the posterior neck portion 53b is set to be larger than the lateral dimension of the lower end of the head 51b, and smaller than the interval between the left and right inner protrusions 73 of the cover body 70.

[0135] The basal end of the neck 53 (the end on the anterior half of the neck 53a side) is connected to the head 51, and the apical part of the neck 53 (the end on the posterior half of the neck 53b side) is connected to the base 54.

[0136] The base 54 is the portion that is inserted into the claw hole 31 of the zipper head body 10. In addition, when the claw 55 of the stop member 50 engages with the zipper tooth 5, it is placed on the base mounting portion 32 of the zipper head body 10. The base 54 has a first base 54a connected to the neck 53, a second base 54b integrally formed on the lower side of the first base 54a, and a base groove portion 54c provided on the bottom surface of the second base 54b.

[0137] The first base 54a is formed such that its lateral dimension is larger than that of the rear half of the neck 53b due to the difference in lamination. The second base 54b is formed such that its lateral dimension is larger than that of the first base 54a due to the difference in lamination.

[0138] The second base 54b has a larger left-right dimension than the first base 54a, thereby allowing the two claw portions 55 to be stably formed in a separated position on the bottom surface of the second base 54b. The second base 54b has a smaller left-right dimension than the claw hole 31. This allows the base 54 of the stop member 50 to be stably inserted into the claw hole 31 of the slider body 10.

[0139] The lamination surfaces formed between the rear half of the neck 53b and the first base 54a, and between the first base 54a and the second base 54b, are each formed as flat surfaces. Furthermore, the lamination surface between the rear half of the neck 53b and the first base 54a is formed to be inclined downwards relative to the lamination surface between the first base 54a and the second base 54b, pointing forward.

[0140] The base recess 54c of the base 54 is formed vertically along the front-rear direction between the two claw portions 55 within the entire front-rear direction of the second base 54b. The base recess 54c has left and right inner wall surfaces facing each other and a bottom surface facing downward. The spacing between the left and right inner wall surfaces of the base recess 54c is set to be larger in the left-right direction than the dimension of the base mounting portion 32 provided in the claw hole 31 of the slider body 10. The bottom surface of the base recess 54c is formed as a flat surface. The bottom surface of the base recess 54c is arranged parallel or substantially parallel to the bottom surface of the second base 54b. Alternatively, the bottom surface of the base recess 54c may be formed as a curved surface that gently curves downward in a convex shape.

[0141] By providing such a base groove 54c in the base 54, when the base 54 of the stop member 50 is inserted into the claw hole 31 of the zipper head body 10 and the claw 55 of the stop member 50 enters the chain tooth guide 16 of the zipper head body 10, the base mounting portion 32 of the zipper head body 10 can be inserted into the base groove 54c of the base 54. In addition, at least a portion of the bottom surface of the groove of the base groove 54c can be in direct contact with the upper surface of the base mounting portion 32.

[0142] Therefore, the base 54 of the stop member 50 can be stably mounted on the base mounting portion 32 of the zipper head body 10. In addition, by using the base mounting portion 32 to support the base 54 of the stop member 50, the depth to which the claw portion 55 of the stop member 50 can enter the zipper tooth guide 16 can be limited, so that the claw portion 55 can properly engage with the zipper tooth 5.

[0143] The stop member 50 has a claw portion 55 comprising: a first claw portion 56 disposed at the front end of the bottom surface of the second base portion 54b; and a second claw portion 57 disposed at the rear end of the bottom surface of the second base portion 54b. The first claw portion 56 and the second claw portion 57 each protrude downward from the bottom surface of the second base portion 54b. The first claw portion 56 is disposed at the front end of the left edge portion of the bottom surface of the second base portion 54b. The second claw portion 57 is disposed at the rear end of the right edge portion of the bottom surface of the second base portion 54b, and is further positioned rearward than the first claw portion 56 in the front-rear direction.

[0144] The first claw portion 56 and the second claw portion 57 are formed with substantially the same shape and the same size. The first claw portion 56 and the second claw portion 57 each have a front claw surface 55a and a rear claw surface 55b, as shown in the side view of the stopping member 50 (e.g., referring to...). Figure 2 The front surface 55a of the claw has a curved surface that is smoothly curved in a convex shape, and the rear surface 55b of the claw has a flat surface. In this case, the rear surface 55b of the claw portion 55 is formed such that, in a side view of the stop member 50, the angle between the rear surface 55b of the claw and the bottom surface (or the extension line of the bottom surface) of the second base portion 54b extending rearward from the rear surface 55b of the claw is greater than 90°.

[0145] The elastic extension 58 of the stop member 50 applies force to the stop member 50 in the rotational direction toward the first claw portion 56 and the second claw portion 57 as they enter the chain guide path 16. This elastic extension 58 has a deformable base end portion 58a connected to the upper end of the head 51, and an elastic plate portion 58b extending obliquely upward and rearward from the deformable base end portion 58a. The deformable base end portion 58a and the elastic plate portion 58b each have a left-right dimension that is the same size as the left-right dimension in the head body portion 51a.

[0146] The deformable base end portion 58a of the elastic extension portion 58 is formed to extend upward from the upper end portion of the head body portion 51a in such a way that the size of the deformable base end portion 58a in the front-rear direction gradually decreases and further bends backward. The elastic sheet portion 58b of the elastic extension portion 58 has a flat first surface (outer surface) facing upward and a flat second surface (inner surface) disposed on the opposite side of the first surface. The elastic sheet portion 58b has an elongated plate-like shape with a constant or substantially constant thickness between the first surface and the second surface. The top end portion (upper end portion) of the elastic sheet portion 58b contacts the inner surface of the top plate portion 71a of the cover body 70, which will be described later, when the pull head 1 is assembled.

[0147] The elastic sheet portion 58b extends straight upward and backward from the deformable base end portion 58a. In this embodiment, the elastic sheet portion 58b is formed such that, in the state where the elastic extension portion 58 is not elastically deformed, for example, the second surface of the elastic sheet portion 58b is inclined at an angle of 15° to 45° relative to the front-rear direction. In addition, the elastic sheet portion 58b is formed such that the vertical dimension of the space portion 59 formed between the elastic sheet portion 58b and the head 51 and neck 53 gradually increases rearward.

[0148] In this embodiment, the stop member 50 is formed such that, for example, the maximum value D1 of the vertical dimension of the space 59 formed between the elastic extension 58 and the neck 53 in the state where the elastic extension 58 is not elastically deformed (refer to...). Figure 1 The minimum value D2 between the rotating shaft portion 52 of the stop component 50 and the inner protrusion 73 when the rotating shaft portion 52 contacts the bottom surface 26b of the insertion recess 26a (refer to) Figure 2 )big.

[0149] Thus, for example Figure 4 As shown, when the rotation axis 52 of the stop member 50 moves upward and contacts the inner protrusion 73 of the cover 70, the elastic extension 58 of the stop member 50 will not contact the neck 53 of the stop member 50, thus ensuring a space 59 between the elastic extension 58 and the neck 53, and allowing the elastic sheet 58b to elastically deform in a manner close to the neck 53.

[0150] As a result, the elastic extension 58 can apply a stronger force to the stop member 50 in the direction of the claw 55 entering the zipper tooth guide 16, thus enabling the claw 55 to engage firmly with the zipper tooth 5. As a result, the zipper pull 1 can have high locking strength.

[0151] The stop member 50 is formed such that the space 59 formed between the head 51 and the elastic extension 58 extends in the front-rear direction to a position overlapping the setting range of the rotation axis 52 of the stop member 50. By forming the space 59 in this way, when the rotation axis 52 of the stop member 50 moves in the vertical direction within the insertion recess 26a of the pull head body 10, the elastic deformation amount of the elastic extension 58 in the stop member 50 can be stably increased or decreased.

[0152] The cover 70 covers at least a portion of the stop member 50 and a portion of the pull tab 40 from above, and is mounted on the front mounting post 21 and the rear mounting post 22 of the pull head body 10. (Example) Figure 1 and Figure 2 As shown, the cover 70 has: a cover body 71 having a box-shaped shape with an opening at the lower end; and front and rear engaging protrusions 72 and left and right inner protrusions 73 provided inside the cover body 71.

[0153] The main body 71 of the cover has: a top plate portion 71a that is long in the front-rear direction; a front wall portion 71b that extends downward from the front end of the top plate portion 71a; a rear wall portion 71c that extends downward from the rear end of the top plate portion 71a; and left and right side wall portions 71d that extend downward from the left and right side edges of the top plate portion 71a.

[0154] The top plate portion 71a of the cover body portion 71 has a shape that curves upward in a convex shape relative to the front-rear direction. The front wall portion 71b and the rear wall portion 71c of the cover body portion 71 are continuously formed from the top plate portion 71a. The front wall portion 71b of the cover body portion 71 has a smooth front end face facing forward, and the rear wall portion 71c has a smooth rear end face facing rearward.

[0155] The left and right sidewalls 71d of the cover body 71 are connected to the top plate 71a, front wall 71b, and rear wall 71c respectively via curved portions. An insertion opening for inserting the mounting shaft 43 of the pull tab 40 is provided at the center of the sidewall 71d in the front-rear direction. The insertion opening of the cover body 71 extends upward from the lower end of the sidewall 71d.

[0156] The engaging protrusions 72 of the cover 70 protrude inwards from the inner wall surfaces of the front wall portion 71b and the rear wall portion 71c of the cover body 71, respectively, in the front-rear direction. Under cross-sectional observation of the cover 70 perpendicular to the left-right direction (e.g.) Figure 2 The front and rear engaging protrusions 72 are formed into a generally triangular shape with an upper end face that engages with the engaging claw portion 24 and an inclined surface that is inclined relative to the vertical direction, so that they can engage with the engaging claw portion 24 of the front mounting post 21 and the rear mounting post 22 of the slider body 10.

[0157] When the cover 70 of this embodiment is installed on the zipper pull body 10, at least one of the cover 70, the front mounting post 21, and the rear mounting post 22 is slightly elastically deformed while the cover 70 covers the front mounting post 21 and the rear mounting post 22 of the zipper pull body 10 from above. This allows the front and rear engaging protrusions 72 of the cover 70 to hook onto the engaging claws 24 provided on the front mounting post 21 and the rear mounting post 22 of the zipper pull body 10 and engage with them. Therefore, the cover 70 can be easily installed relative to the front mounting post 21 and the rear mounting post 22 of the zipper pull body 10 via a snap-fit ​​engagement.

[0158] The left and right inner protrusions 73 of the cover 70 protrude inward in the left and right directions from the left and right sidewall portions 71d of the cover body 71, respectively. Furthermore, the left and right inner protrusions 73 are formed to protrude downward from the top plate portion 71a of the cover body 71. The left and right inner protrusions 73 each have a front protrusion 73a extending rearward from the front wall portion 71b of the cover body 71 and a rear protrusion 73b extending forward from the rear wall portion 71c of the cover body 71.

[0159] The left and right front protrusions 73a are positioned in contact with or close to the upper surface of the layer gap portion 25 and the mounting wall portion 26 on the front mounting post 21 of the slider body 10 from above. This allows the insertion recess 26a provided in the mounting wall portion 26 to be sealed from above (or covered from above). Therefore, it is possible to prevent the rotation shaft portion 52 of the stop member 50 held within the insertion recess 26a of the mounting wall portion 26 from dislodging from the insertion recess 26a.

[0160] The left and right rear protrusions 73b are configured to contact or approach the layer difference portion 25 on the rear mounting post 22 of the zipper body 10 from the upper side.

[0161] Next, the method of manufacturing the zipper head 1 of this embodiment by assembling the four components described above: the zipper head body 10, the zipper tab 40, the stop component 50, and the cover 70 will be explained.

[0162] First, a pull tab 40 is placed on the upper wing plate 11 of the zipper head body 10. At this time, the mounting shaft portion 43 of the pull tab 40 is inserted between the mounting wall portion 26 and the pull tab guide portion 27 in the zipper head body 10, and the front mounting post 21 or the rear mounting post 22 is inserted into the opening window of the pull tab 40.

[0163] Next, a stop member 50 is placed relative to the zipper head body 10 on which the pull tab 40 is mounted. At this time, the lower end portion 51b of the stop member 50 is inserted into the receiving recess 28 provided on the upper wing plate 11 of the zipper head body 10. In addition, the base 54 and the claw portion 55 of the stop member 50 are inserted into the claw hole 31 of the zipper head body 10, and the base 54 is placed in the base mounting portion 32 provided in the claw hole 31.

[0164] Next, a cover 70 is installed relative to the zipper head body 10, which houses the pull tab 40 and the stop member 50. At this time, the cover 70 is brought closer to the zipper head body 10 in a tilted position, for example, so that the cover 70 covers the mounting shaft 43 of the pull tab 40 and the stop member 50 from above, and with the front (or rear) side of the cover 70 facing downwards. Furthermore, the engaging protrusion 72 on the front (or rear) side of the cover 70 is hooked onto the engaging claw 24 provided on the front mounting post 21 (or rear mounting post 22) of the zipper head body 10.

[0165] Next, the rear end (or front end) of the inclined cover 70 is pressed downward in a forward-backward direction. This allows the cover 70 to be easily mounted to the front mounting post 21 and rear mounting post 22 of the zipper head body 10 using a snap-fit ​​mechanism.

[0166] The zipper pull 1 of this embodiment is manufactured by performing the assembly process described above. The assembly operation of attaching the cover 70 to the zipper pull body 10 using the snap-fit ​​method described above can be easily and reliably performed manually or by using an automatic assembly machine.

[0167] Additionally, by installing the cover 70 onto the zipper head body 10, such as Figure 2 and Figure 3 As shown, the elastic extension 58 of the stop member 50 is pressed by the cover 70 and elastically deforms in such a way that the elastic sheet portion 58b approaches the neck 53. Through such elastic deformation of the elastic extension 58, an elastic force is applied to the stop member 50 in the direction that forces the claw portion 55 into the chain tooth guide 16 of the zipper head body 10.

[0168] In this embodiment, the zipper head 1, manufactured as described above, is slidably mounted on the left and right rows of zipper teeth connected to a pair of left and right zipper teeth. This creates a zipper where the left and right rows of zipper teeth can engage and disengage via the sliding of the zipper head 1.

[0169] In the zipper pull 1 of this embodiment, manufactured as described above, all four components—the zipper pull body 10, the pull tab 40, the stop member 50, and the cover 70—can be formed from synthetic resin. This improves the recyclability of the zipper pull 1.

[0170] Additionally, when the pull tab 40 of the slider 1 is in a free state and the slider 1 is not in operation, such as Figure 3 As shown, the elastic extension 58 of the stop member 50 elastically deforms, thereby generating an elastic force that applies force to the stop member 50. Through this elastic force, the two claws 55 of the stop member 50 can enter the zipper tooth guide 16 of the zipper head body 10 and be inserted between two adjacent zipper teeth 5.

[0171] Therefore, each claw portion 55 of the stop member 50 can contact the front end of the zipper tooth body portion 6 (especially the upper half of the front end of the zipper tooth body portion 6) and engage with the zipper tooth 5. At this time, the claw portion 55 of the stop member 50 can also be inserted between two zipper teeth 5 to a position where it is slightly separated from one or both of the zipper teeth 5.

[0172] By engaging the claw 55 of the stopping member 50 with the zipper teeth 5 as described above, the zipper head 1 is stopped, automatically locking it in a position where it is difficult to move relative to the stop position of the zipper teeth. In particular, by engaging the claw 55 with the zipper teeth 5 through contact between the rear end face 55b of the claw 55 and the zipper teeth 5, the zipper head 1 is made even more difficult to move in the sliding direction (rearward) that separates the left and right zipper teeth.

[0173] In the pull head 1 of this embodiment, the claw portion 55 of the stop member 50 is as follows: Figure 3 In the normally locked state, where it is inserted between the two zipper teeth 5, the rotation shaft 52 of the stop member 50 is held at its lower end within the insertion recess 26a of the zipper head body 10, in contact with the bottom surface 26b of the recess 26a. In this case, although an elastic force is generated by the elastic deformation of the elastic extension 58, the amount of elastic deformation (deflection) of the elastic extension 58 can be minimized because the rotation shaft 52 is located at the lower end of the insertion recess 26a. Therefore, the zipper head 1 can be properly stopped while suppressing the deterioration of the synthetic resin caused by elastic deformation.

[0174] Additionally, for example, from Figure 3 In the typical locked state, for example, when the zipper pull 1 is subjected to a force such as backward movement without the operation of the pull tab 40, the pawl 55 of the stop member 50 is pressed forward by the zipper tooth 5 engaged by the pawl 55. At this time, the rear end face 55b of the pawl of the stop member 50 is formed such that the angle between it and the bottom surface of the second base 54b is greater than 90°. In addition, the tooth body 6 of the zipper tooth 5 is provided with an inclined surface 6a that gradually decreases upward in the front-rear direction of the zipper tooth 5.

[0175] Therefore, while the inclined surface 6a of the zipper tooth 5 contacts the rear end face of the claw 55 of the stop member 50, the claw 55 is pressed forward, for example... Figure 4 As shown, the stop member 50 can be oriented towards the rotating shaft 52 as the center. Figure 4 The paper rotates clockwise. At the same time, the rotating shaft 52 of the stop member 50 can be moved upward within the insertion recess 26a of the pull head body 10 and abut against the lower end of the inner protrusion 73 of the cover body 70.

[0176] This allows the elastic extension 58 of the stop member 50 to deform further, increasing the amount of elastic deformation of the elastic extension 58. As a result, the stop member 50 can be subjected to a stronger force through the elastic extension 58, so that the claw 55 of the stop member 50 is firmly engaged with the zipper teeth 5. Therefore, even if the zipper pull 1 is subjected to a force in the rearward direction, the zipper pull 1 can be locked more forcefully so that it will not move from the stop position (or is difficult to move from the stop position).

[0177] Furthermore, in this embodiment, by abutting the rotation axis 52 of the stop member 50 against the inner protrusion 73 of the cover 70, excessive elastic deformation of the elastic extension 58 of the stop member 50 can be prevented. This prevents or suppresses excessive load on the stop member 50, thus making it difficult for the stop member 50 to undergo plastic deformation.

[0178] Furthermore, for example, if the elastic extension 58 is significantly deformed after the slider 1 is subjected to a force that moves backward as described above, and the force applied to the slider 1 is removed, the elastic deformation of the elastic extension 58 can be reduced again by the elastic recovery of the elastic extension 58 while the slider 1 is functioning as a stopper.

[0179] In this way, in the zipper pull 1 of this embodiment, in the normal non-operational state where no force is applied to move the zipper pull 1, the elastic deformation of the elastic extension 58 of the stop member 50 can be reduced, thus properly performing the stopping function of the zipper pull 1. Furthermore, when the zipper pull 1 is subjected to a force that moves it while the claw 55 of the stop member 50 is engaged with the zipper teeth 5, the elastic deformation of the elastic extension 58 can be temporarily increased, thereby improving the locking strength of the zipper pull 1.

[0180] Furthermore, in the zipper pull 1 of this embodiment, when the zipper pull 1 is stopped relative to the zipper teeth, there is a situation where the claw portion 55 of the stopping member 50 abuts against the zipper teeth 5 from above and is held in a state of resting on the upper surface of the zipper teeth 5. In this case, for example... Figure 5 As shown, the rotation shaft portion 52 of the stop member 50 is held at the lower end of the insertion recess 26a of the zipper head body 10, so even if the claw portion 55 of the stop member 50 hits the upper surface of the zipper tooth 5, the increase in the elastic deformation of the elastic extension portion 58 can be suppressed.

[0181] For example, in the case of the zipper pull 1 of this embodiment, the elastic deformation (deflection) of the elastic extension 58 when the claw 55 of the stop member 50 is on the upper surface of the zipper tooth 5 is reduced by about 40% compared to conventional zipper pulls where, for example, the rotation axis 52 of the stop member 50 cannot move in the vertical direction and can be rotated while in contact with the lower end of the inner protrusion 73 of the cover 70.

[0182] Therefore, even if the stop member 50 is placed on the zipper teeth 5 for an extended period of time as described above, the elastic deformation of the elastic extension 58 can be maintained at a small amount. This makes it difficult for deformation (plastic deformation) caused by creep to occur in the stop member 50, preventing or suppressing a decrease in the elastic force generated by the elastic extension 58. Therefore, the zipper pull 1 of this embodiment can stably ensure an appropriate locking strength that keeps the zipper pull 1 in the stop position for a long time.

[0183] Furthermore, this utility model is not limited to the above-described embodiments. As long as it has a substantially the same structure as this utility model and performs the same function, various modifications can be made.

[0184] For example, in the above-described embodiment, the stop member 50 has two claws 55, a first claw 56 and a second claw 57. However, the stop member of this invention may also have only one claw, protruding downwards from the bottom of the base.

[0185] Furthermore, in the stop member 50 of the above embodiment, the first claw portion 56, which is disposed on the front side compared to the second claw portion 57, is located on the left edge of the bottom surface of the second base portion 54b, and the second claw portion 57, which is disposed on the rear side, is located on the right edge of the bottom surface of the second base portion 54b. However, in this utility model, the first claw portion on the front side may be disposed on the right edge of the bottom surface of the second base portion, and the second claw portion on the rear side may be disposed on the left edge of the bottom surface of the second base portion.
