[0006] The pull tab auxiliary component is configured to be installed in the pull tab body through a through hole (mounting hole), thus not affecting the installation state of the other through hole (mounting hole) and the mounting post of the pull tab body. Furthermore, a gap is formed between the mounting hole and the mounting post, so the pull tab body may wobble relative to the mounting post depending on the size of the gap. In this invention, the mounting post is referred to as the pull tab mounting part. Utility Model Content

[0007] This utility model was made in view of the above situation, and its purpose is to install the pull tab auxiliary component on the pull tab body and to prevent the pull tab body from shaking relative to the pull tab mounting part as much as possible.

[0008] The zipper of this utility model includes: a zipper head, which includes a zipper head body and a zipper mounting part; and a zipper tab, which includes a zipper tab body and a zipper tab auxiliary part.

[0009] The zipper pull body has a toothed passage that runs through the front-to-back direction. The zipper tab mounting part is formed by the cooperation of a through hole that runs through the left-to-right direction with the zipper pull body, and protrudes upward from the upper surface of the zipper pull body when viewed from the side.

[0010] The pull tab body, when viewed from the side, extends radially around the through hole and is mounted to the zipper pull in a manner that allows it to rotate in the front-to-back direction. A first through hole and a second through hole are formed in the pull tab body. The pull tab mounting portion passes through the first through hole. The second through hole is parallel to the first through hole and is located radially outward relative to the first through hole. This utility model relates to such a pull tab auxiliary component for zippers.

[0011] The pull tab auxiliary component is installed on the pull tab body by passing through the second through hole. The pull tab auxiliary component includes: a base; a first neck and a second neck; and a first head and a second head.

[0012] A base portion is disposed on one side of the pull tab body. A first neck and a second neck extend from the base portion, respectively penetrating through the first and second through holes. A first head extends from the first neck and, in cooperation with the base portion, clamps the pull tab body in the through direction. A second head extends from the second neck and, in cooperation with the base portion, clamps the pull tab body in the through direction.

[0013] The first neck, first head, and base may or may not contact the pull tab mounting part, but in order to prevent the pull tab body from wobbling relative to the pull tab mounting part, the following structure is preferred.

[0014] At least one of the first neck, the first head, and the base portion is in contact with the pull tab mounting portion.

[0015] To prevent the pull tab body from wobbling in the left-right direction relative to the pull tab mounting part, the following structure is preferred.

[0016] At least one of the first neck, the first head, and the base has a groove that opens inward toward the radial direction and accommodates a portion of the pull tab mounting portion.

[0017] The contact state between the pull tab auxiliary component and the pull tab mounting part is not important, but in order to prevent the pull tab body from shaking relative to the pull tab mounting part, the following structure is preferred.

[0018] The bottom surface of the groove facing the radial direction is the surface that presses a part of the pull tab mounting part together.

[0019] Whether or not the pull tab auxiliary component has a structure that extends outward from the second head is acceptable, but in order to make it easier to hold the pull tab, the following structure is preferred.

[0020] The pull tab auxiliary component has a gripping portion that extends outward from the second head in a radial direction and is located further outward than the pull tab body in the radial direction.

[0021] The pull tab may consist of only the pull tab body and pull tab accessories, but in order to make the pull tab easier to operate, it is preferable to install other components on the pull tab body as described below.

[0022] The base portion has a recess that opens outward in a radial direction and communicates with a second through hole. When viewed from the through direction of the pull tab body, the second neck and the second head are located outward relative to the recess, and the outer radial portion of the second through hole communicates with a space formed inside the recess.

[0023] When viewed from the through direction of the pull tab body, the pull tab auxiliary component can be located within the outer periphery of the pull tab body, but for the purpose of miniaturization, the following structure is preferred.

[0024] When viewed from the through direction of the pull tab body, the pull tab auxiliary component is located within the outer periphery of the pull tab body.

[0025] Utility Model Effect

[0026] In the pull tab auxiliary component of this invention, the first head and the second head are mounted to the pull tab body by clamping it together with the base. Furthermore, in this pull tab auxiliary component, not only is the second neck inserted through the second through hole and mounted to the pull tab body, but the pull tab mounting portion and the first neck also pass through the first through hole. Therefore, compared to a pull tab auxiliary component that is mounted to the pull tab body by simply passing through the second through hole, the first through hole is filled, thereby better preventing the pull tab body from wobbling relative to the pull tab mounting portion.

[0061] 51 Ring-shaped body 52 Holding component main body Detailed Implementation

[0062] The zipper to which this invention applies, as is well known, comprises: a pair of toothed zipper straps; a zipper pull for opening and closing the pair of toothed zipper straps; and a pull tab for operating the zipper pull. The pair of toothed zipper straps comprises: a pair of opposing straps; and a pair of zipper teeth, each fixed along an opposing side edge of the pair of straps. The zipper pull engages and disengages the pair of zipper teeth. Figure 1 The image shows a state in which the pull head 1 is integral with a portion of the pull tab 2 of the first embodiment, but separate from the other parts of the pull tab 2.

[0063] The orientation is determined below, with the zipper placed on a flat surface as a reference.

[0064] "Back-to-back direction" refers to the direction in which the slider 1 moves when opening and closing the pair of toothed chain straps. "Back-to-back direction" is also the direction in which the pull tab 2 rotates above the slider 1 when opening and closing the pair of toothed chain straps. "Forward direction" refers to the direction in which the slider 1 moves when closing the pair of toothed chain straps. "Forward direction" is... Figure 1 The "upward direction" refers to the direction in which the zipper head 1 moves when the pair of chain straps are opened. The "backward direction" is... Figure 1 The downward direction in the middle.

[0065] "Left-right direction" refers to the direction in which a pair of chain teeth face each other, and is the direction of displacement when a pair of chain teeth are engaged and disengaged. "Left-right direction" is also called "width direction." "Left direction" is... Figure 1 The left direction in the middle. The right direction is... Figure 1 The right direction in the middle. Additionally, the "left and right directions" are directions perpendicular to the front and back directions.

[0066] "Up and down direction" refers to the direction orthogonal to the front-back and left-right directions. "Up and down direction" is... Figure 1 The direction perpendicular to the paper. "Up direction" is... Figure 1 The direction perpendicular to the paper is the direction closest to the front. "Down direction" is... Figure 1 The direction perpendicular to the paper surface is the direction towards the depth side.

[0067] "Radial direction" refers to the following direction: when the direction in which the pull tab 2 moves the pull head 1 is reversed, if the movement of the pull tab 2 is observed from the side, the pull tab 2 rotates in a circular arc in the front-back direction with the pull head 1 as the center. The direction of the straight line connecting the center of the arc and a point on the arc is the "radial direction".

[0068] like Figure 2 , Figure 3 As shown, a through hole 1a for mounting the pull tab 2 is formed in the upper part of the slider 1. The through hole 1a is a hole through which the slider 1 passes in the left-right direction. Specifically, the through hole 1a is formed by the slider body 11 located below the through hole 1a and the pull tab mounting portions 12 located in front of, behind and above the through hole 1a. That is, the slider 1 includes the slider body 11 and the pull tab mounting portions 12. The pull tab mounting portions 12 are in a state where they protrude upward from the upper surface of the slider body 11 when viewed from the side. The pull tab mounting portions 12 are located at the center in the left-right direction relative to the slider body 11.

[0069] Additionally, the zipper pull body 11 includes a tooth passage 13 through which a pair of chain teeth pass and a pair of belt grooves 14 through which a pair of belts pass as its internal space. Both the tooth passage 13 and the pair of belt grooves 14 extend through the zipper pull body 1 in the front-to-back direction. The front side of the tooth passage is bifurcated, while the rear side is integrally formed. The pair of belt grooves 14 communicate with the left and right sides of the tooth passage 13. Furthermore, in the illustrated example, the front sides of the pair of belt grooves 14 are separated in the left-to-right direction, while the rear sides are integrally formed.

[0070] The illustrated zipper pull 1 has a locking mechanism 15. The locking mechanism 15 prevents the zipper pull 1 from moving in the front-to-back direction relative to a pair of chain teeth without operating the pull tab 2. Specifically, the locking mechanism 15 includes: a pair of posts 16 protruding upwards from the zipper pull body 11 in a left-to-right facing position; a shaft 17 mounted on the pair of posts 16; a locking claw 18 supported on the shaft 17 in a swingable manner and entering the chain tooth passage 13 at a position rearward of the shaft 17; and a spring 19 that pushes the locking claw 18 upwards at a position forward of the shaft 17, thereby pressing the top of the locking claw 18 downwards. The spring 19 is received between a hole 11a formed in the upper surface of the zipper pull body 11 and the locking claw 18. The illustrated zipper pull 1 forms a pull tab mounting portion 12 via a large portion of the locking mechanism 15.

[0071] When the pull tab 2 is operated on the pull head 1, it is in a taut state. The taut state is such that it extends in a straight line along the radial direction. When the pair of toothed chains are open, the pull tab 2 is positioned rearward relative to the pull tab mounting part 12; when the pair of toothed chains are closed, the pull tab 2 is positioned forward relative to the pull tab mounting part 12. The detailed structure of the pull tab 2 will be described below based on the state where the pull tab 2 is taut rearward. In this case, the radial direction is consistent with the front-rear direction.

[0072] The pull tab 2 includes: a pull tab body 3, which is installed in the pull tab mounting part 12; and a pull tab auxiliary part 4, which is installed in the pull tab body 3.

[0073] like Figure 1 As shown, the pull tab body 3 is symmetrical from left to right and is triangular in shape. Furthermore, the corners of the triangle in the pull tab body 3 are rounded arcs bulging outwards towards the vertices of a pure triangle. The width of the pull tab body 3 gradually increases towards the rear. The pull tab body 3 is, for example, made of metal. The pull tab body 3 includes: a frame 31; and a center strip 32, which divides the internal space of the frame 31 in the front-rear direction.

[0074] The frame 31 includes: a bottom frame 31a, which is parallel to the left-right direction; and a pair of side frames 31b, which are inclined relative to the front-back direction. The pair of side frames 31b are connected at their front ends. The rear ends of the pair of side frames 31b are connected to the left and right ends of the bottom frame 31a. The center slat 32 is mounted on the pair of side frames 31b in a state parallel to the bottom frame 31a.

[0075] A first through hole 34 and a second through hole 35 are formed on the inner side of the frame 31, separated by a center strip 32 in the front-rear direction. The through direction of the first through hole 34 is parallel to the through direction of the second through hole 35 and is consistent with the vertical direction. The pull tab mounting part 12 passes through the first through hole 34. The first through hole 34 is triangular. The corners of the first through hole 34 are arcs bulging towards the apex of a pure triangle. The width of the first through hole 34 gradually increases towards the rear (outer radial direction). The second through hole 35 is a shape in which the dimension in the left-right direction is longer than the dimension in the front-rear direction. The second through hole 35 includes two sides facing each other in the front-rear direction and two sides facing each other in the left-right direction. The two sides facing each other in the front-rear direction are parallel in the left-right direction. The two sides facing each other in the left-right direction are semicircular, and the tangents to the two endpoints of each semicircle are the two sides facing each other in the front-rear direction.

[0076] The pull tab auxiliary component 4 is, for example, made of resin and capable of elastic deformation. The pull tab auxiliary component 4 is installed on the pull tab body 3 in a detachable manner using this elastic deformation. The pull tab auxiliary component 4 is symmetrical from left to right. Figure 1 , Figure 5 , Figure 6 As shown, the pull tab auxiliary member 4 includes: a base portion 40 disposed on the lower surface of one side of the pull tab body 3; a first neck 41 and a second neck 42 extending from the base portion 40 and passing through a first through hole 34 and a second through hole 35, respectively; a first head 43 and a second head 44 extending from the first neck 41 and the second neck 42 respectively, facing the upper surface of the pull tab body 3; and a grip portion 45 extending rearward from the second head 44. Additionally, the pull tab auxiliary member 4 has a recessed groove 46 on its front surface.

[0077] The first neck 41 and the second neck 42 extend upward from the upper surface of the base portion 40. The first neck 41 and the second neck 42 are fitted into the first through hole 34 and the second through hole 35 in a manner that prevents them from moving in the front-back and left-right directions. Details are as follows. The second neck 42 faces the first neck 41 from the rear. A neck gap S1 that separates the first neck 41 and the second neck 42 in the front-back direction is formed between the first neck 41 and the second neck 42. The first neck 41 and the second neck 42 sandwich the middle strip 32 from the front and rear in the neck gap S1. The first neck 41 is the size that prevents it from moving in the left-right direction inside the first through hole 34, and the second neck 42 is the size that prevents it from moving in the left-right direction inside the second through hole 35.

[0078] The first head 43 rises upward from the upper end of the first neck 41 and extends backward. The second head 44 also rises upward from the upper end of the second neck 42 and extends backward. The first head 43 and the second head 44 are separate. In the example shown, a head gap S2 is formed between the first head 43 and the second head 44 in the front-back direction. The head gap S2 is smaller than the neck gap S1, i.e., S2 < S1. The first head 43 and the base 40 sandwich the middle strip 32 from above and below, and the second head 44 and the base 40 sandwich the bottom frame 31a from above and below.

[0079] The base portion 40 is plate-shaped. The base portion 40 extends rearward and laterally relative to the second neck 42. When viewed from above, the base portion 40, when mounted on the pull tab body 3, is located within the outer periphery, specifically, within the inner periphery of the pull tab body 3. The base portion 40 partially covers the first through hole 34 from below; specifically, it covers the rear portion of the first through hole 34 from below, and also covers the entire second through hole 35 from below.

[0080] The groove 46 extends vertically through the center of the width of the front surfaces of the first head 43, the first neck 41, and the base 40. The bottom surface (the front-facing surface) of the groove 46 is in close contact with a portion of the pull tab mounting portion 12, rather than merely contacting it. That is, when a portion of the pull tab mounting portion 12 is accommodated in the groove 46, the groove 46 elastically deforms to become deeper, thus ensuring close contact between the groove 46 and the pull tab mounting portion 12. Assuming the groove 46 does not elastically deform in its natural state, in this natural state, an insertion gap S3 (see reference 3) is formed between the frame 31 (the front end of the first through hole 34) facing the front of the groove 46 in the front-rear direction and the bottom surface of the groove 46 for inserting the pull tab mounting portion 12. Figure 6 (E)). On the other hand, such as Figure 3 As shown, the pull tab mounting portion 12 has a portion (received portion) 12a that is housed in the groove portion 46. A setting interval S4 for housing the received portion 12a is formed between the rear end of the received portion 12a and the front end of the first through hole 34. The setting interval S4 is longer than the insertion interval S3, i.e., S4 > S3. That is, the rear end of the received portion 12a is located further rearward than the bottom surface of the groove portion 46 in its natural state. Due to this relationship, the groove portion 46 undergoes elastic deformation due to the pull tab mounting portion 12. Specifically, the bottom surface (the surface facing forward) of the groove portion 46 elastically deforms and becomes a concave surface because the received portion 12a of the pull tab mounting portion 12 is pressed and housed in the groove portion 46.

[0081] When viewed from above, the boundary between the gripping part 45 and the second head 44 forms the outer periphery of the pull tab body 3. The entire length L1 of the gripping part 45 in the front-back direction is longer than the entire length L2 of the pull tab body 3 in the front-back direction, i.e., L1 > L2.

[0082] The pull tab auxiliary member 4 of the first embodiment is installed on the pull tab body 3 by clamping the pull tab body 3 from above and below through the cooperation of the first head 43 and the second head 44 with the base part 40. That is, in the pull tab auxiliary member 4 of the first embodiment, the first neck 41 and the second neck 42 are engaged with the first through hole 34 and the second through hole in a manner that prevents them from moving in the front-back and left-right directions, so they are installed in a manner that makes it difficult to wobble relative to the pull tab body 3. In addition, in the pull tab auxiliary member 4 of the first embodiment, the first head 43 can undergo elastic deformation. Therefore, when the first neck 41 and the second neck pass through the first through hole 34 and the second through hole 35, and when the first neck 41 and the second neck are pulled out from the first through hole 34 and the second through hole 35, the first head 43 undergoes elastic deformation, which momentarily increases the head gap S2 and passes through the first through hole 34, and then the first head 43 returns to its original shape. As a result, the pull tab auxiliary member 4 of the first embodiment can be attached to and detached from the pull tab body 3.

[0083] Furthermore, in the pull tab auxiliary member 4 of the first embodiment, not only is the second neck 42 installed on the pull tab body 3 through the second through hole 35, but the pull tab mounting part 12 and the first neck 41 also pass through the first through hole 34. Therefore, compared with the pull tab auxiliary member that is installed on the pull tab body 3 through the second through hole 35, the first through hole 34 is filled, which can better prevent the pull tab body 3 from shaking relative to the pull tab mounting part 12.

[0084] In the first embodiment, the front surface of the pull tab auxiliary member 4 contacts the pull tab mounting portion 12. Therefore, compared to pull tab auxiliary members where the front surface is separate from the pull tab mounting portion 12, it is more effective in preventing the pull tab body 3 from wobbling relative to the pull tab mounting portion 12. Furthermore, the pull tab auxiliary member 4 of the first embodiment is in close contact with the pull tab mounting portion 12 when its front surface undergoes elastic deformation, thus further preventing the pull tab body 3 from wobbling relative to the pull tab mounting portion 12. Additionally, in the pull tab auxiliary member 4 of the first embodiment, the first neck 41, the first head 43, and the base portion 40 are all in close contact with the pull tab mounting portion 12.

[0085] Furthermore, the bottom surface of the groove 46 is the surface that presses the received portion 12a of the pull tab mounting portion 12. By receiving the received portion 12a in the groove 46, the bottom surface of the groove 46 undergoes elastic deformation and becomes concave, thereby preventing the pull tab body 3 from wobbling relative to the pull tab mounting portion 12. Moreover, in the pull tab auxiliary member 4 of the first embodiment, by causing the groove 46 to undergo elastic deformation and clamping the pull tab mounting portion 12 from both sides in the groove 46, wobbling relative to the pull tab mounting portion 12 in the left-right direction can be prevented. As a result, wobbling of the pull tab body 3 relative to the pull tab mounting portion 12 in the left-right direction can also be prevented.

[0086] Furthermore, the pull tab auxiliary member 4 of the first embodiment has a gripping part 45, so the pull tab 1 can be operated by gripping the gripping part 45.

[0087] exist Figure 7 , Figure 8 The pull tab 2a of the second embodiment is shown. The pull tab 2a of the second embodiment differs from the pull tab 2 of the first embodiment in that, in addition to the pull tab body 3 and the pull tab auxiliary member 4a, it also includes a dedicated gripping member 5 which is a separate component from the pull tab auxiliary member 4a, as well as the structure of the pull tab auxiliary member 4a.

[0088] The gripper 5 includes: an annular body 51, which is installed on the pull tab body 3 in a state of being inserted into the second through hole 35; and a gripper body 52, which extends rearward from the annular body 51. The gripper 5 is, for example, made of metal. The annular body 51 is a flat plate or a plate bent into a C-shape before being installed on the bottom frame 31a of the pull tab body 3, and becomes annular after being installed on the bottom frame 31a through plastic deformation. The gripper body 52 extends in the front-rear direction and has an elongated shape.

[0089] like Figure 9 As shown, the pull tab auxiliary member 4a differs from the pull tab auxiliary member 4 of the first embodiment in that it does not have the gripping part 45 of the first embodiment; the first neck 41a, the second neck 42a, the first head 43a, and the second head 44a are respectively provided separately in the left-right direction; the base part 40a covers a portion of the second through hole 35. Details are as follows.

[0090] The first neck 41a and the second neck 42a extend downward from the lower surface of the base portion 40a.

[0091] The first neck 41a includes a first left neck 411 and a first right neck 412 facing each other in the left-right direction. The first left neck 411 and the first right neck 412 are respectively disposed on the left and right sides of the groove 46a in a separate manner.

[0092] The second neck 42a includes a second left neck 421 and a second right neck 422 facing each other in the left-right direction. The second left neck 421 and the second right neck 422 are respectively disposed on the left and right sides of the groove 46a, and are separately disposed in a position further to the left than the first left neck 411 and a position further to the right than the first right neck 412.

[0093] The first head 43a protrudes downward from the lower end of the first neck 41a and extends to the left and right sides. The first head 43a includes a first left head 431 and a first right head 432 facing each other in the left-right direction. The first left head 431 protrudes downward from the lower end of the first left neck 411 and extends to the left. The first right head 432 protrudes downward from the lower end of the first right neck 412 and extends to the right.

[0094] The second head 44a protrudes downward from the lower end of the second neck 42a and extends outward. The second head 44a includes a second left head 441 and a second right head 442 facing each other in the left-right direction. The second left head 441 protrudes downward from the lower end of the second left neck 421 and extends to the left. The second right head 442 protrudes downward from the lower end of the second right neck 422 and extends to the right.

[0095] like Figure 10As shown, the base portion 40a is disposed on the upper surface of one side of the pull tab body 3. The base portion 40a is triangular in shape, following the outer periphery of the pull tab body 3. Furthermore, the base portion 40a is located within the outer periphery of the pull tab body 3. In addition, the first head 41a and the second head 42a are also located within the outer periphery of the pull tab body 3. Therefore, the pull tab auxiliary member 4a of the second embodiment is located within the outer periphery of the pull tab body 3.

[0096] The base portion 40a includes: a groove portion 46a that is recessed rearward from the center portion in the width direction of the front surface; and a recess portion 47a that is recessed forward from the center portion in the width direction of the rear surface.

[0097] The depth (dimension in the front-to-back direction) of the groove 46 is set to the length at which the bottom surface of the groove 46 will not contact the pull tab mounting portion 12. That is, the insertion interval S3a is longer than the setting interval S4, i.e., S3a > S4.

[0098] The width of the groove 46 is set to be the same as the width of the receiving portion 12a of the pull tab mounting portion 12. That is, the groove 46 receives the receiving portion 12a in a sandwiched state from the left and right. The recess 47a communicates with the rear portion 35a of the second through hole 35. The front portion of the second through hole 35 is covered from above by the base portion 40a.

[0099] The recess 47a opens rearward (outward in the radial direction). The width of the recess 47a is greater than the width of the groove 46.

[0100] When viewed from above and below, the pull tab body 3 and pull tab auxiliary member 4a, which are formed as a single unit, communicate with the rear part (outer part in the radial direction) 35a of the second through hole 35. The annular body 51 passes through the space 47a1 and the rear part 35a of the second through hole 35 and is mounted on the bottom frame 31a of the frame 31.

[0101] The pull tab auxiliary member 4a of the second embodiment is the same as the pull tab auxiliary member 4 of the first embodiment in that it also includes a base part 40a, a first neck 41a, a second neck 42a, a first head 43a, and a second head 44a. Therefore, it is installed on the pull tab body 3 in the same way as the first embodiment, which can prevent the pull tab body 3 from shaking relative to the pull tab mounting part 12.

[0102] Furthermore, when viewing the pull tab auxiliary member 4a of the second embodiment from the top and bottom, the pull tab auxiliary member 4a is located within the outer periphery of the pull tab body 3, and is therefore smaller than, for example, a pull tab auxiliary member having a portion protruding to the outer periphery of the pull tab body 3.

[0103] Furthermore, in the pull tab auxiliary member 4a of the second embodiment, the base portion 40a has a recess 47a. When viewed from above, the second neck 42a and the second head 44a are located on the outside of the recess 47a. The rear portion 35a of the second through hole 35 communicates with the space portion 47a1 formed inside the recess 47a, thus allowing the dedicated gripper 5 to be mounted on the bottom frame 31a of the pull tab body 3. In addition, in the pull tab auxiliary member 4a of the second embodiment, the recess 47a accommodates the portion 12a of the pull tab mounting portion 12 in a clamped state from the left and right, thus preventing the pull tab body 3 from wobbling in the left and right direction relative to the pull tab mounting portion 12.

[0104] This invention is not limited to the above-described embodiments and can be appropriately modified without departing from its essence. In the above embodiments, the pull tab body 3 is triangular when viewed from the through direction, but this invention is not limited to this and may also be quadrilateral, circular, or other shapes. In addition, in the above embodiments, the pull head 1 is configured to have a locking mechanism 15 and a portion of the pull tab mounting portion 12 (locking claw 18) is movable, but this invention is not limited to this, and the pull tab mounting portion 12 may also be fixed in a state where it does not move relative to the upper surface of the pull head body 11.
