[0104] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0105] In this instruction manual, the front-back direction refers to the length direction of the zipper pull, and is the direction along which the zipper pull slides in the zipper. That is, the direction in which the zipper pull moves to engage the left and right zipper teeth (shoulder side direction) is front, and the direction in which it moves to disengage the zipper teeth (rear side direction) is rear.

[0106] The up and down direction refers to the height of the zipper pull. For example, it is the direction perpendicular to the upper and lower wing plates of the zipper pull body. The direction relative to the zipper pull plate that is installed on the zipper pull body is upward, and the opposite direction is downward.

[0107] The left and right directions are the width direction of the slider, which is orthogonal to the length and height directions of the slider.

[0108] In this specification, a plan view refers to the view taken from below. Furthermore, regarding the pull tab assist, the front-to-back, up-and-down, and left-to-right directions are determined based on the state of the zipper pull with the assist installed tilted towards the rear of the zipper head. The direction of the pull tab assist is independent of the positional relationship between the zipper head and the pull tab body. That is, the front-to-back direction of the zipper head does not need to be consistent with the front-to-back direction of the pull tab assist. Additionally, the direction of the assist head refers to the direction of its front end in the front-to-back direction of the pull tab assist.

Figure 2 This is a perspective view of the zipper puller of Embodiment 1 installed from a lower angle. Figures 3 to 6 These are, respectively, a top view, a bottom view, a right side view, and a cross-sectional view taken from the right side at the center of the left-right direction of the zipper puller head on which the zipper pull tab of Embodiment 1 is installed. Figure 7 yes Figure 6 Enlarged view of the neck of the auxiliary device and the periphery of the mounting hole in the sectional view shown. Figures 8 to 11 These are, respectively, a top view, a bottom view, a right side view, and a cross-sectional view of the zipper puller body at the center of the left and right directions when the auxiliary head of the zipper puller in the first direction is inserted into the mounting hole of the puller body in the first direction.

[0111] The zipper pull includes the zipper body 30 and the zipper pull tab.

[0112] The slider head body 30 has a shape that is symmetrical about its central plane in the left-right direction. The slider head body 30 includes: an upper wing plate 31; a lower wing plate 32, which is disposed separately from the upper wing plate 31; a connecting post 33, which connects the front ends of the upper wing plate 31 and the lower wing plate 32; left and right upper flange portions 34, which are disposed on the left and right side edges of the upper wing plate 31 and extend toward the lower wing plate 32; left and right lower flange portions 35, which are disposed on the left and right side edges of the lower wing plate 32 and extend toward the upper wing plate 31; a pair of front and rear mounting posts, which stand upright from the upper surface of the upper wing plate 31; and a cover 36, which is mounted on the front and rear mounting posts. A locking pin is disposed within the cover 36, which forms an automatic stop mechanism for the slider head.

[0113] The slider body 30 is manufactured by die-casting metal materials such as aluminum alloy and zinc alloy. Furthermore, in this invention, the material or manufacturing method of the slider body 30 is not particularly limited; it can also be made of hard resin or ceramic.

[0114] The zipper pull tab of this utility model includes a pull tab body 10 and a pull tab auxiliary device 20. The zipper pull tab is installed on the upper surface of the zipper head body 30 by inserting a cover 36 fixed to the zipper head body 30 into the post connection hole 14 of the pull tab body 10.

[0115] Figures 12 to 14 These are, respectively, the top view, bottom view, and right side view of the pull tab body 10 of this embodiment 1. Figure 15 This is an enlarged 3D view of the area near mounting hole 11 on the lower surface of the pull tab body, viewed from the oblique front. Figures 16 to 18 These are, respectively, the top view, bottom view, and right side view of the pull-tab auxiliary device 20 in this embodiment 1.

[0116] The pull tab body 10 includes: a through mounting hole 11; a retaining groove 12 disposed along a portion of the outer periphery of the mounting hole 11; and an inclined surface 13 extending between the mounting hole 11 and the retaining groove 12.

[0117] The pull tab body 10 is made of rigid resins such as polyamide, polypropylene, polyacetal, and polybutylene terephthalate, and may contain reinforcing fibers such as glass fiber, colorants, ultraviolet absorbers, and other additives. Furthermore, in this invention, the material of the pull tab body 10 only needs to be harder than the auxiliary head 23 in the pull tab auxiliary device 20; it can also be metal, ceramic, or an elastomer harder than the auxiliary head 23.

[0118] Mounting hole 11 is approximately rectangular with the left and right sides as its longer sides. Mounting hole 11 allows the first direction ( Figure 9 The auxiliary head 23 (shown to the left) passes through, but cannot make the second direction (shown to the left) Figure 4The auxiliary head 23 (shown facing forward) passes through. The shape of the mounting hole 11 is not particularly limited as long as it allows the auxiliary head 23 in the first direction to pass through but prevents it from passing through in the second direction. The shape of the mounting hole 11 is determined by the shape of the auxiliary head 23; for example, in a plan view, it can be elliptical, oblong, triangular, rectangular, trapezoidal, pentagonal, hexagonal, star-shaped, gear-shaped, heart-shaped, etc. From the viewpoint of preventing the pull tab auxiliary 20 from falling off, the angle formed by the first and second directions is preferably 30 degrees to 150 degrees, more preferably 45 degrees to 135 degrees, further preferably 60 degrees to 120 degrees, even more preferably 75 degrees to 105 degrees, even more preferably 80 degrees to 100 degrees, even more preferably 85 degrees to 95 degrees, and most preferably 90 degrees.

[0119] In this embodiment 1, the mounting hole 11 is formed with a protrusion 112 extending inwardly along the entire circumference of its hole wall 111. The protrusion 112 is formed in the hole wall 111 at least at the portion that clamps the auxiliary neck 22 in the second direction.

[0120] The retaining groove 12 is a portion that accommodates the auxiliary head 23 in the second direction. By accommodating the auxiliary head 23 in the retaining groove 12, the pull tab auxiliary 20 is mounted on the pull tab body 10.

[0121] The retaining groove 12 is approximately rectangular with its long side in the front-to-back direction. The retaining groove 12 includes a bottom surface 121 and side walls 122, which are the walls that contact the auxiliary head 23 when it is to be rotated clockwise or counterclockwise within the retaining groove 12. The retaining groove 12 is used to accommodate the auxiliary head 23, and its shape, arrangement, and number are determined according to the shape of the auxiliary head 23.

[0122] In this embodiment 1, the retaining groove 12 is formed with a similar shape that is slightly smaller than the size of the portion of the auxiliary head 23 that is housed in the retaining groove 12, as described later. Therefore, the auxiliary head 23 is housed in the retaining groove 12 in a compressed state, making it difficult for the auxiliary head 23 to move within the retaining groove 12 and preventing it from falling out. Furthermore, the retaining groove 12 only needs to be able to compress at least a portion of the auxiliary head 23 during housing; for example, it can compress only in the left-right direction, only in the front-back direction, or both in the left-right and front-back directions. Moreover, it is also possible to compress only a portion of the height in the vertical direction along either the left-right or front-back direction, or along both directions.

[0123] An inclined surface 13 extends between the mounting hole 11 and the retaining groove 12. The inclined surface 13 is the area through which the auxiliary head 23 passes when rotating from a first direction toward a second direction. In this embodiment 1, the inclined surface 13 is approximately fan-shaped, centered on the intersection of the mounting hole 11 and the retaining groove 12. The inclined surface 13 is formed such that the edge on the mounting hole 11 side is deeper the further away from the center of the fan shape, and the edge on the retaining groove 12 side is shallower the further away from the center of the fan shape. The inclined surface 13 is formed to continuously slope upwards while bending along the rotation direction of the auxiliary head 23 from the edge on the mounting hole 11 side to the edge on the retaining groove 12 side; that is, the pull tab body 10 constituting the inclined surface 13 is formed in a continuous and gradually thickening manner from the mounting hole 11 to the retaining groove 12, therefore the inclined surface 13 gradually becomes shallower from the mounting hole 11 toward the retaining groove 12. Figure 15 Furthermore, the shallowing and deepening of the inclined surface 13 refer to the decrease and increase of the interval (distance) in the vertical direction (pulling sheet thickness direction) from any specific lower surface of the pull tab body 10 (e.g., the lower surface disposed around the mounting hole 11) to the inclined surface 13. In this embodiment 1, the inclined surface 13 is formed at the portion that the observation aid head 23 passes through when rotating clockwise from the first direction toward the second direction from below (in... Figure 13 The upper left and lower right of the mounting hole 11), but the inclined surface 13 can also be formed in the part that passes through when rotating counterclockwise as viewed from below, according to the rotation direction when the auxiliary head 23 is installed (in Figure 13 The mounting hole 11 can be formed in the lower left and upper right positions as described above. By setting the inclined surface 13 in both positions, the degree of freedom in the direction of inserting the auxiliary head 23 into the mounting hole 11 is increased, thus enabling efficient installation operations.

[0124] The pull-tab aid 20 includes: aid neck 22; aid body 21 connected to one side of aid neck 22; and aid head 23 connected to the other side of aid neck 22 and extending further outward than aid neck 22.

[0125] In this embodiment 1, the entire pull-tab auxiliary device 20 is capable of elastic deformation. The pull-tab auxiliary device 20 is made of elastically deformable resins such as polyurethane-based rubber, polybutadiene-based rubber, silicone rubber, fluoropolymer-based rubber, and natural rubber, and may also contain additives such as fillers, colorants, and UV absorbers. The pull-tab auxiliary device 20 only needs to be capable of elastic deformation to the extent that the auxiliary device head 23 can extend beyond the inclined surface 13 during installation. The auxiliary device neck 22 and the auxiliary device body 21 can also be formed of materials that cannot undergo elastic deformation, such as metal, ceramic, or hard resin. Alternatively, the auxiliary device head 23 can also be obtained by coating an elastically deformable resin with a core formed of metal, ceramic, or hard resin.

[0126] The neck 22 of the auxiliary device is an elongated oval that is slightly longer in the front-to-back direction than in the left-to-right direction. The major axis of the neck 22 in the front-to-back direction is slightly longer than the distance between the mounting holes 11 in the front-to-back direction. The neck 22 can be rotated within the mounting holes 11, and its shape can be exemplified in a plan view as a circle, ellipse, elongated oval, rectangle, trapezoid, pentagon, hexagon, star, etc.

[0127] The auxiliary head 23 is approximately rectangular with its long side being the front-to-back direction of the pull tab auxiliary. The auxiliary head 23 is formed into a cone shape that tapers towards the neck 22 of the auxiliary head. In a plan view, the first direction ( Figure 9 The outer edge of the auxiliary head 23 (shown facing left) is slightly larger than the outline of the mounting hole 11, allowing it to pass through the mounting hole 11 through elastic deformation. In the plan view, the second direction ( Figure 4 The outer edge of the auxiliary head 23 (shown facing forward) protrudes significantly from the outline of the mounting hole 11 and cannot pass through it. The auxiliary head 23 needs to undergo elastic deformation to pass through the mounting hole 11, thus making it difficult to fall out and preventing the pull tab auxiliary head 23 from detaching during installation. Alternatively, the outer edge of the auxiliary head 23 in the first direction in the plan view may be within the outline of the mounting hole 11. This allows the auxiliary head 23 to pass through the mounting hole 11 without elastic deformation, thus requiring less force to pass through and improving workability. The auxiliary head 23 can be any shape that allows it to pass through the mounting hole 11 in the first direction but not in the second direction, i.e., a shape with different lengths in the two intersecting directions. Examples include ellipses, oblong shapes, rectangles, trapezoids, pentagons, hexagons, stars, gears, and hearts.

[0128] The method of installing the pull tab assist 20 onto the pull tab body 10 in this embodiment 1 will be described using the accompanying drawings.

[0129] First, insert the auxiliary head 23 into the mounting hole 11 in the first direction and allow it to pass through the mounting hole 11. Figure 19 ).

[0130] In the plan view, the outer edge of the auxiliary head 23 in the first direction is slightly larger than the outline of the mounting hole 11, but since the auxiliary head 23 can elastically deform, it can pass through the mounting hole 11. In addition, in this embodiment 1, the auxiliary head 23 is formed into a cone shape with its tip tapering, so the auxiliary head 23 can be easily inserted into the mounting hole 11.

[0131] Next, rotate the auxiliary head 23 toward the second direction ( Figure 20 ).

[0132] During rotation, the auxiliary head 23 elastically deforms while crossing the inclined surface 13. A gap is formed between the outer peripheral surface of the auxiliary head 23 in the first direction (passing through the mounting hole 11) and the hole wall 111 of the mounting hole 11, causing them to separate in the rotational direction of the auxiliary head 23. This gap allows the auxiliary head 23, inserted into the mounting hole 11, to move easily within it. Therefore, when the auxiliary head 23 rotates in the second direction, compared to a case without a gap, the auxiliary head 23 can more forcefully contact the hole wall 111 of the mounting hole 11, and it is easier for the auxiliary head 23 to ascend the inclined surface 13. As the auxiliary head 23 rotates in the second direction, it contacts the ridge between the inclined surface 13 and the mounting hole 11 sequentially from the deeper side to the shallower side, gradually deforming as it ascends the inclined surface 13. The auxiliary head 23 deforms gradually rather than all at once, so the amount of deformation required to initially climb onto the inclined surface 13 is smaller, allowing the operator to rotate the pull tab auxiliary 20 relative to the pull tab body 10 with less force. Furthermore, since the elastic deformation of the auxiliary head 23 when passing over the upper surface of the inclined surface 13 can be minimized, the pressure between the elastically deformed auxiliary head 23 and the inclined surface 13 can be reduced, thereby preventing damage to the inclined surface 13, especially the ridge line, due to this pressure.

[0133] Finally, the auxiliary head 23 is rotated to the second orientation, thereby housing the auxiliary head 23 in the retaining slot 12. Figure 21 ).

[0134] Because the inclined surface 13 is formed such that one side of the retaining groove 12 is shallower, the height from the bottom surface 121 of the side wall surface 122 adjacent to the inclined surface 13 is maintained. Therefore, the auxiliary head 23 is difficult to elastically deform over the side wall surface 122, and rotation of the auxiliary head 23 from the second direction to the first direction is hindered. Furthermore, in this embodiment 1, since the auxiliary head 23 is housed in the retaining groove 12 in a compressed state, the auxiliary head 23 is difficult to move within the retaining groove 12, preventing the auxiliary head 23 from rotating outside the retaining groove 12. Moreover, the auxiliary neck 22 is clamped and compressed by the hole wall 111, and the protrusion 112 of the hole wall 111 is embedded in the auxiliary neck 22. Figure 7 Therefore, the movement of the assist neck 22 is hindered, and the rotation of the assist head 23 connected to the assist neck 22 is also hindered.

[0135] (Example 2)

[0136] Figures 22 to 24These are the top view, bottom view, and AA sectional view of the bottom view of the pull tab body in this embodiment 2. Figures 25 to 27 These are the top view, bottom view, and AA sectional view of the zipper pull tab in this embodiment 2.

[0137] In this embodiment 2, the pull tab body 40 has a recess 423 formed across the bottom surface 421 of the retaining groove 42 and the side wall surface 422 adjacent to the inclined surface 43. In the shape of the zipper pull tab in this embodiment 2, except that the recess 423 is formed across the bottom surface 421 and the side wall surface 422 of the retaining groove 42, the other structures are substantially the same as those of the zipper pull tab in embodiment 1.

[0138] The recess 423 is formed by penetrating the pull tab body 40. The recess 423, penetrating the upper surface of the pull tab body 40, is covered by the pull tab auxiliary body 21 and therefore not visible when the pull tab auxiliary 20 is installed, thus preserving its aesthetic appeal. Figure 25 Furthermore, the recess 423 may not penetrate the pull tab body 40, and the recess 423 may be provided only on the bottom surface 421 or only on the side wall surface 422, and may also be provided on the bottom surface 421 and the side wall surface that is not adjacent to the inclined surface 43. Figure 23 Between the right sidewall of the middle.

[0139] If a force is applied to the auxiliary head 23 housed in the retaining groove 42, the auxiliary head 23 interferes with the retaining groove 42 and undergoes elastic deformation. In this embodiment 2, the zipper pull tab can release at least a portion of the volume of elastic deformation that occurs when the auxiliary head 23 rotates towards the recess 423 into the recess 423, thus reducing the amount of upward elastic deformation of the auxiliary head 23. If the upward elastic deformation of the auxiliary head 23 increases to a certain value, it will cause it to extend beyond the side wall 422; however, in this embodiment 2, the reduced upward elastic deformation of the auxiliary head 23 makes the pull tab auxiliary 20 more difficult to detach.

[0141] Figure 28 , Figure 29 These are the bottom view and the AA sectional view of the pull tab body of embodiment 3. Figure 30 , Figure 31 These are the bottom view and the BB sectional view of the zipper pull tab in this embodiment 3.

[0142] In this embodiment 3, the pull tab body 50 is formed such that the bottom surface 521 of the retaining groove 52 deepens toward the side wall surface 522. In the shape of the zipper pull tab in this embodiment 3, except that the end on the side of the side wall surface 522 is formed the deepest because the bottom surface 521 of the retaining groove 52 deepens toward the side wall surface 522, the other structures are substantially the same as the zipper pull tab in embodiment 1.

[0143] In this embodiment 3, the bottom surface 521 of the retaining groove 52 is formed to its deepest point at the end of the side wall 522, thus increasing the height of the side wall 522 from the bottom surface 521. Furthermore, the increased height of the side wall 522 further prevents the auxiliary head 23 from elastically deforming and crossing the side wall 522. Moreover, in this embodiment 3, since the upper surface of the auxiliary head 23 is flat, a gap exists between the upper surface of the auxiliary head 23 housed in the retaining groove 52 and the bottom surface 521 of the retaining groove 52. Furthermore, since at least a portion of the volume of the auxiliary head 23 that elastically deforms due to interference with the retaining groove 52 during rotation is released into the gap between the auxiliary head 23 and the bottom surface 521, the upward elastic deformation of the auxiliary head 23 is reduced, making it more difficult for the zipper puller 20 to detach.

[0145] Figure 32 , Figure 33 This is a bottom view of the pull tab body and pull tab auxiliary device in Embodiment 4. Figure 34 This is a bottom view of the zipper pull tab of embodiment 4 being installed on the zipper pull tab of the zipper pull tab body.

[0146] In the zipper pull tab of this embodiment 4, the retaining groove 62 has a mating protrusion 621, and the auxiliary head 73 has a mating recess 731. The auxiliary head 73 is housed in the retaining groove 62 when the mating protrusion 621 and the mating recess 731 are engaged. In the form of the zipper pull tab of this embodiment 4, except that the retaining groove 62 and the auxiliary head 73 have mating protrusions 621 and mating recesses 731 that engage with each other, the other structures are substantially the same as those of the zipper pull tab of embodiment 1.

[0147] The zipper pull tab of this embodiment 4 can make it more difficult for the auxiliary head 73, which is housed in the retaining groove 62, to rotate by engaging the engaging protrusion 621 with the engaging recess 731.

[0148] The retaining groove 62 and the auxiliary head 73 only need to have a mating protrusion and a mating recess that fit together, and their shape and position are not particularly limited. Alternatively, the retaining groove 62 can have a mating recess and the auxiliary head 73 can have a mating protrusion, or both the retaining groove 62 and the auxiliary head 73 can have more than one mating recess and more than one mating protrusion.
