Description

Technical Field

[0001] This utility model relates to a zipper with a stop bar and a zipper product having a stop bar disposed at the end of the chain teeth. Background Technology

[0002] Generally, zippers are widely used as opening and closing devices for products such as clothing, daily necessities, industrial materials, and various seats in automobiles, trains, and aircraft. Typically, zippers used in these products have: a pair of zipper teeth forming rows of teeth on the side edges of the zipper strip; and a slider that slides along the rows of teeth.

[0003] On the other hand, it is known that by directly sewing a toothed component, which consists of multiple teeth attached to a rope-like fixing component, to the component on which the zipper is to be installed, the zipper and the component on which the zipper is to be installed can be integrated without using a zipper tape. In such a zipper without using a zipper tape, after sewing the left and right rows of teeth to the component on which the zipper is to be installed, the zipper pull needs to be inserted. In addition, the installation of the stop blocks located at the ends of the rows of teeth needs to be performed after inserting the zipper pull.

[0004] Patent Document 1 describes a method for forming a zipper without using a zipper tape, and a resin stopper is provided at the end of the zipper teeth. This stopper has: a receiving body portion capable of receiving the ends of the zipper teeth in the longitudinal direction; and a base body portion extending outward in a plate-like shape from the receiving body portion, wherein the receiving body portion has at least one through hole that communicates with the space on the lower surface side of the base body portion. Thus, when the ends of the zipper teeth are inserted into the interior space of the receiving body portion and a rope-like fixing member passes through the through hole and contacts the lower surface of the base body portion, the base body portion and fixing member of the stopper are fixed to the component on which the zipper is to be mounted by sewing or the like.

[0005] In addition, it is known that the zipper stop with zipper tape is composed of a riveting member and a back plate. The riveting member has a protruding pin that penetrates a through hole in the back plate and engages with the through hole, and will be permanently deformed (see, for example, Patent Document 2).

[0010] Problems to be solved by utility models

[0011] However, the stopper described in Patent Document 1 requires operations such as sewing the base body and fixing member of the stopper to the component on which the zipper is to be installed. Furthermore, before this, the ends of the zipper teeth must be inserted into the internal space of the housing body, and the rope-like fixing member must pass through the through hole to contact the lower surface of the base body. Therefore, an improved stopper with good workability is sought for zippers that do not use zipper tape.

[0012] Furthermore, in zippers that do not use zipper tape, since the fixing member extending from the end of the chain teeth is not sewn to the member on which the zipper is to be installed, it is not possible to use the zipper stop with zipper tape as described in Patent Document 2.

[0013] This invention was made in view of the problems mentioned above, and its purpose is to provide a zipper with a stop code and a zipper product that can be easily installed in a zipper without using a zipper tape.

[0037] The following describes in detail, based on the accompanying drawings, an embodiment of the present invention, including a zipper with a stop code and a zipper product.

[0038] Furthermore, in this specification, "vertical direction" refers to the sliding direction of the zipper pull, encompassing the length and width directions of the chain teeth. Specifically, the direction in which the zipper pull slides to engage a pair of chain teeth is designated "upper," and the direction in which it slides to separate the left and right chain teeth is designated "lower." Additionally, "left-right direction" refers to the direction in which a pair of chain teeth are arranged, orthogonal to the sliding direction of the zipper pull. It can also be referred to as the front-back direction of the chain teeth, with the direction of the chain teeth facing the engaging object designated "front," and the opposite side designated "rear." Furthermore, "front-back direction" is a direction orthogonal to both the vertical and left-right directions, and can also be referred to as the height direction of the chain teeth. Additionally, sometimes, based on the accompanying drawings, a pair of components is described as "left and right" components.

[0039] The zippered product 1 in this embodiment is a garment (clothing) with a zipper. A zipper is formed at the placket of the front of the zippered product 1. Figure 1 The zipper with stop code shown is 5 (hereinafter referred to as "zipper"). In addition, the left and right fabrics 6 of the zipper product 1, which serve as the precursor of the opening and closing part (especially the placket part), are provided with left and right zipper tooth mounting edges 7 for mounting the left and right zipper tooth members 10 described later.

[0040] In this case, the fabric 6 (also called garment fabric) constituting the placket of the zippered product 1 becomes the component for mounting the zipper to the zipper teeth 10. Therefore, as... Figure 1As shown, the zipper 5 formed in this embodiment has: a pair of left and right chain teeth members 10, which are directly fixed to the fabric 6 to form a chain tooth row 11; a zipper head 30, which enables the left and right chain tooth rows 11 to engage and disengage; and a stop bar 70, which is installed at the lower end of the chain tooth row 11.

[0041] In this embodiment, there are no particular limitations on the thickness, shape, and softness of the fabric 6, which is the component to be fitted with the zipper. However, the fabric 6 is preferably formed in a manner that allows the sewing machine needle to pierce through it during the sewing process.

[0042] In this embodiment, the zipper tooth mounting edge 7 provided on the fabric 6 has a predetermined size in the width direction of the zipper tooth member 10 from the opposite side edges of the fabric 6 that constitute the left and right placket portions toward the inside of the fabric 6, and is continuously formed along the length direction of the zipper tooth member 10.

[0043] The left and right chain tooth mounting edges 7 are formed by folding the side edges of the fabric 6, which are the cut ends, back in a U-shape towards the back side. As a result, the chain tooth mounting edges 7 are locally thicker than other parts of the thinner fabric 6, thereby increasing the strength of the chain tooth mounting edges 7.

[0044] Furthermore, even if the sewing thread 21 pierces the zipper tooth mounting edge 7 as described later, the zipper tooth mounting edge 7 is not easily broken by the sewing thread 21, thus improving the durability of the zipper tooth mounting edge 7. Moreover, by increasing the strength of the zipper tooth mounting edge 7, the zipper tooth component 10 can be firmly fixed to the zipper tooth mounting edge 7, and the position and orientation of each zipper tooth (hereinafter also referred to as a tooth) 40 fixed to the zipper tooth mounting edge 7 can be stabilized.

[0045] In addition, Figure 1 In the diagram, only the main body 31 of the zipper pull 30 is shown, and the pull tab held in the main body 31 is omitted. The zipper pull 30 has a structure that is essentially the same as conventional zipper pulls, and can smoothly engage and disengage the left and right zipper tooth components 10 that are directly fixed to the zipper tooth mounting edge 7 of the zipper product 1.

[0046] In this embodiment, the chain tooth member 10 includes a rope-shaped fixing member 15 and a plurality of independent chain teeth 40 mounted on the fixing member 15. The fixing member 15 is a rope-shaped component. The plurality of independent chain teeth 40 are mounted on the fixing member 15 at certain intervals in the width direction of the chain teeth 40 to form a chain tooth row 11. The chain tooth members 10 are grouped in pairs. Figure 1 The left and right chain tooth components 10 are sewn along the ends of the left and right chain tooth mounting edges 7 of the zipper product 1, respectively.

[0047] The fixing member 15 is a rope (also called a knitted yarn) formed by wrapping a core yarn composed of multiple multifilaments in a pocket knit section made of multiple knitted yarns, and is flexible. Furthermore, the fixing member 15 used in this invention is not particularly limited as long as it can accommodate multiple chain teeth 40; for example, it can also be formed from monofilament or ply yarn (ply rope). The fixing member 15 is a member with a roughly circular cross-section orthogonal to the length direction, such as... Figure 2 As shown, the fixing member 15 has a flat cross-sectional shape due to deformation within the chain tooth 40. However, in this invention, the cross-sectional shape of the fixing member is not particularly limited.

[0048] Each chain tooth 40 of the chain tooth component 10 is formed, for example, by injection molding a thermoplastic resin such as polyacetal onto the fixing component 15, thus becoming integral with the fixing component 15 and covering a portion of the entire outer peripheral surface of the fixing component 15. Furthermore, in this invention, the material of the chain teeth 40 is not limited to the aforementioned synthetic resin; for example, other synthetic resins or metals may be used to form the chain teeth. Additionally, the chain tooth component of this invention is not limited to components formed by injection molding chain teeth onto a fixing component; for example, it also includes components formed by fixing chain teeth pre-shaped to a predetermined form to a fixing component using welding or bonding.

[0049] like Figures 2-4 As shown, the plurality of chain teeth 40 in this embodiment include: engaging chain teeth 40A, which engage the chain teeth 40 of a pair of chain tooth members 10 on the left and right sides; and receiving chain teeth 40B, at least a portion of which is received inside the stop 70. The engaging chain teeth 40A include: an engaging portion 42, which engages with the chain teeth 40 of the chain tooth member 10 on the engaging object side; and a main body portion 41, which extends from the engaging portion 42 toward the front-back direction of the chain teeth 40 (in a direction orthogonal to the extension direction of the fixing member 15 when viewed from above) and is fixed to the fixing member 15.

[0050] The engaging chain tooth 40A has a front half 43 and a back half 44, which are separated based on a position approximately at the center of the engagement chain tooth 40A in the height direction (in this embodiment, the center of the fixing member 15 in the height direction of the engagement chain tooth 40A). The front half 43 and the back half 44 have different shapes. In this case, the surface of the front half 43 and the back surface of the back half 44 are orthogonal to the height direction of the engagement chain tooth 40A and are arranged parallel to each other.

[0051] The front half of the chain tooth 43 has: a front engagement head 43b that engages with a meshing chain tooth on the meshing object side; and a front body 43a that extends from the front engagement head 43b toward the rear of the chain tooth member 10, and clamps the fixing member 15 between the front body 43a and the back half of the chain tooth 44.

[0052] The surface-side main body 43a is formed in a generally rectangular parallelepiped shape. In addition, the surface-side engaging head 43b is in a generally triangular shape, with the width of the chain teeth gradually decreasing towards the tip of the surface-side engaging head 43b.

[0053] The back half of the chain tooth 44 includes: a back-side engaging head 44c that engages with the chain tooth on the engaging side; a back-side neck 44b that extends from the back-side engaging head 44c toward the rear of the chain tooth and has a necked shape; and a back-side main body 44a that extends further toward the rear of the chain tooth from the back-side neck 44b. In this embodiment, a fixing member 15 is clamped between the back-side neck 44b and the back-side main body 44a and the surface half of the chain tooth 43.

[0054] The front-side main body portion 43a is located on the front side relative to the fixing member 15 in the height direction of the chain tooth 40, and the back-side neck 44b and the back-side main body portion 44a are located on the back side relative to the fixing member 15 in the height direction of the chain tooth 40.

[0055] The side of the tooth of the surface half 43 of the chain tooth contacts the side of the tooth of the surface meshing head 43b of the meshing tooth 40A on the meshing side, and the back half 44 of the chain tooth engages with the back half 44 of the meshing tooth 40A on the meshing side using the back neck 44b and the back meshing head 44c, thereby engaging the left and right chain tooth rows 11. Therefore, the surface meshing head 43b, the back neck 44b and the back meshing head 44c constitute the meshing part 42.

[0056] Furthermore, on the side portion of the main body 41 that is disposed opposite to the fabric 6, that is, the side portion of the main body 41 that is the opposite side to the side where the engagement portion 42 is located relative to the fixing member 15 (behind the chain tooth 40), a recess 45 is provided along the width direction of the chain tooth 40 that is recessed toward the fixing member 15.

[0057] In addition, a connecting portion 46 is provided in the center of the width direction of the chain tooth 40 within the recess 45. This connecting portion 46 connects the front main body portion 43a and the back main body portion 44a and contacts the fixing member 15 on the reverse engagement side.

[0058] Therefore, such as Figure 3 As shown, the main body 41 of the chain tooth 40 covers the entire outer peripheral surface of the fixing member 15, which is held at the center of the chain tooth 40 in the height direction, at the center of the chain tooth 40 in the width direction.

[0059] On the other hand, at the center of the width direction of the chain tooth 40, the opposite side edge of the chain tooth mounting edge 7 abuts against the connecting portion 46, and the top end portion of the opposite side edge of the chain tooth mounting edge 7 becomes a shape that expands along the height direction of the chain tooth 40 and is housed in the recess 45.

[0060] In addition, the tooth 40B has different shapes on the left and right sides of the tooth member 10 and the left and right sides of the tooth member 10.

[0061] That is, one of the two receiving teeth 40B1 on one side of the pair of chain teeth has: a first head 52, which has a through hole 51; and a first body part 53, which extends from the first head 52 in the left and right direction and is fixed to the fixing member 15. The two receiving teeth 40B1 are formed in a face-back symmetrical manner with reference to the approximate middle position in the height direction of the receiving teeth 40B.

[0062] On the other hand, the storage tooth 40B3, which is disposed between the two storage teeth 40B1 on one side of the other of the three storage teeth 40B2, 40B3, 40B4 on the other side of the pair of left and right chain teeth members, has: a second head 62, which has notches 61 on both sides in the width direction of the storage tooth 40B without interfering with the first head 52; and a second body portion 63, which extends from the second head 62 toward the rear of the storage tooth 40B and is fixed to the fixing member 15. The storage tooth 40B3 is formed with the approximate middle position in the height direction of the storage tooth 40B as a reference and is symmetrical about the front and back.

[0063] Additionally, of the three storage teeth 40B2, 40B3, 40B4 on the other side of the pair of chain teeth 10, the two storage teeth 40B2, 40B4 located on the outer side of the two storage teeth 40B1 on one side become engagement portions 42 (surface engagement head 43b, back engagement head 44c) relative to the engaging teeth 40A, having a notch 61 on the leaf side in the width direction of the storage teeth 40B without interfering with the first head 52 of the storage teeth 40B1 on one side.

[0064] The stop 70 has a front member 71 and a back member 81 for holding and storing the chain teeth 40B. The front member 71 has: a front plate-shaped portion 72 facing the surface of the chain teeth 40B; two protrusions 73 arranged vertically and protruding vertically from the front plate-shaped portion 72 toward the back member 81 at the middle of the left-right direction; a front flange portion 74 extending from the front plate-shaped portion 72 toward the back member 81 in the back-side direction and facing the rear end face of the chain teeth 40B; and a front protrusion 75 extending from the front plate-shaped portion 72 toward the back member 81 in the back-side direction and facing the side face of the chain teeth 40B. Furthermore, the rear end face of the chain teeth 40B and the front flange portion 74 can abut. Additionally, the side face of the chain teeth 40B and the front protrusion 75 can abut.

[0065] Regarding the outer diameter of the protrusion 73, as described later, in order to prevent bending when riveting the top part of the protrusion 73, the outer diameter of the protrusion 73 is configured to fit into the through hole 51 for receiving the chain tooth 40B1. That is, the inner diameter of the through hole 51 is slightly larger than the outer diameter of the protrusion 73.

[0066] The surface flange portion 74 is formed at both ends of the surface plate portion 72 in the vertical direction, and the surface protrusion portion 75 extends continuously from the surface flange portion 74 in the horizontal direction.

[0067] Additionally, the back member 81 includes: a back plate-like portion 82 facing the back of the receiving tooth 40B; two holes 83 arranged vertically, for inserting two protrusions 73 at the middle of the front plate-like portion 72 in the left-right direction; a back flange portion 84 extending from the back plate-like portion 82 toward the front member 71 in the back-side direction and facing the rear end face of the receiving tooth 40B; and a back protrusion portion 85 extending from the back plate-like portion 82 toward the front member 71 in the back-side direction and facing the side face of the receiving tooth 40B. Furthermore, the rear end face of the receiving tooth 40B and the back flange portion 84 can abut against each other. Additionally, the side face of the receiving tooth 40B and the back protrusion portion 85 can abut against each other.

[0068] The dorsal flange portion 84 is formed at both ends of the dorsal plate portion 82 in the vertical direction, and the dorsal protrusion portion 85 extends continuously from the dorsal flange portion 84 in the horizontal direction.

[0069] Furthermore, on the left and right sides of the outer flange portion 74 of the outer member 71, at positions corresponding to the rear ends of the two storage teeth 40B1 and the rear ends of the storage teeth 40B3, there is also a flange protrusion 76 extending toward the back member 81 in the direction of the back of the watch.

[0070] Similarly, on the left and right back flange portions 84 of the back member 81, at positions corresponding to the rear end face of the receiving chain tooth 40B1 and the rear end face of the receiving chain tooth 40B3, flange protrusions 86 extending toward the front member 71 in the direction of the back of the watch are also provided.

[0071] In addition, the flange protrusions 76 and 86 are configured to increase the strength of the front flange 74 and the back flange 86. The flange protrusions 76 and 86 can abut against each other or be slightly separated.

[0072] In addition, around the two holes 83 on the back side of the back plate-shaped portion 82 of the back side member 81, two recesses 87 are formed from the recesses of the surrounding surface.

[0073] Furthermore, the inner diameter of the hole 83 of the back member 81 is preferably configured to be slightly larger than the outer diameter of the protrusion 73 so that the protrusion 73 fits into the hole 83, thereby preventing buckling during riveting.

[0074] The front-side member 71 and the back-side member 81 of the stopper 70 are also formed, for example, by injection molding a thermoplastic resin such as polyoxymethylene. In addition, in the present utility model, the material of the stopper 70 is not limited to the above synthetic resin, and for example, other synthetic resins or metals can also be used to form the stopper.

[0075] Therefore, when forming the zipper 5 with stoppers, first, the tooth elements 10 are arranged at positions adjacent to the tooth mounting edge portion 7 of the fabric 6 on the outer side in the width direction, and are fixed to the tooth mounting edge portion 7 of the fabric 6 by sewing with a sewing thread 21 using a zigzag sewing machine. In this case, the sewing thread 21 is formed to be zigzagged with respect to the length direction by flat sewing. Thus, the tooth elements 10 are fixed to the tooth mounting edge portion 7 in a state where the main body portion 41 of each tooth 40 is in contact with the tooth mounting edge portion 7 of the fabric 6.

[0076] Here, a zigzag sewing machine is a sewing machine that can swing a sewing needle along a cross direction intersecting with the feeding direction of the sewing machine and sew the fabric 6 etc. in a zigzag manner by flat sewing. In addition, the swing of the sewing needle in the zigzag sewing machine is sometimes referred to as a zigzag swing (Japanese: 千鳥振り). By using such a zigzag sewing machine and setting coordinate data such as the X coordinate (position in the feeding direction) and the Y coordinate (position in the cross direction) that become the needle dropping position of the sewing needle and performing sewing, it is possible to easily make the sewing thread 21 formed after sewing bend in a zigzag shape in the above cross direction with respect to the feeding direction of the zigzag sewing machine.

[0077] The sewing thread 21 formed by flat sewing has: a top thread (needle thread) that travels on the surface of the tooth mounting edge portion 7 and contacts the surface side half portion of the fixing member 15; and a bobbin thread that travels on the back surface of the tooth mounting edge portion 7 and contacts the back side half portion of the fixing member 15. In this case, the top thread and the bobbin thread are arranged in a position relationship that is symmetric with each other in the up-down direction except for the portion where the two cross.

[0078] In addition, conventional ordinary sewing threads are used for the top thread and the bobbin thread of the flat sewing. Also, the top thread and the bobbin thread in the flat sewing cross (interleave) at the piercing position where the fixing sewing portion 20 pierces the tooth mounting edge portion 7 and the position where they contact the outer peripheral surface of the fixing member 15.

[0079] After that, the front-side member 71 and the back-side member 81 constituting the stopper 70 are installed with respect to the receiving teeth 40B of the pair of left and right tooth elements 10. First, as Figure 6As shown in (b), the receiving teeth 40B are disposed on the surface of the surface plate-like portion 72, which is divided by the surface flange portion 74 and the surface protrusion portion 75 of the surface member 71. In this state, the two protrusions 73 pass through the through holes 51 formed by the two receiving teeth 40B1.

[0080] Then, the front member 71, which is equipped with a tooth 40B, covers the back member 81 by inserting the protrusion 73 into the hole 83, thereby... Figure 7 As shown in (b), the chain teeth 40B are disposed on the surface of the back plate-shaped portion 82, which is divided by the back flange portion 84 and the back protrusion portion 85 of the back member 81.

[0081] Then, use Figure 8 The punch 90 and die 95 shown are riveted to the top end of the protrusion 73 of the surface member 71. Furthermore, Figure 8 The diagram shows one punch 90 and one die 95, but in this embodiment, due to the presence of two protrusions 73, there are two punches 90 and two dies 95. Furthermore, in this embodiment, riveting is performed without heating.

[0082] Here, the punch 90 has a first recess 91 at the center of the annular protrusion 93 to receive the top end of the protrusion 73 during riveting, and a second recess 92 around the annular protrusion 93 to receive the resin after riveting. The bottom surface of the first recess 91 is a flat surface.

[0083] Therefore, the top end of the protrusion 73 is riveted to form a riveting flange 77 with an outer diameter larger than that of the protrusion 73, and is engaged with the recess 87 of the back member 81. Thus, the front member 71 and the back member 81 are fixed to each other.

[0084] As explained above, in the zipper product 1 of this embodiment, the plurality of teeth 40 of the left and right pair of zipper teeth 10 have engaging teeth 40A that allow the teeth 40 of the left and right pair of zipper teeth 10 to mesh with each other, and receiving teeth 40B that are at least partially housed inside the stop bar 70. The stop bar 70 has a front member 71 and a back member 81 that hold the receiving teeth 40B. Furthermore, the front member 71 has a protrusion 73, and the back member 81 has a hole 83 into which the protrusion 73 is inserted. The front member 71 and the back member 81 are fixed to each other by means of the through hole 83 and the protrusion 73 of the through hole 51 formed in the receiving teeth 40B. Thus, in a zipper without a zipper tape, the stop bar 70 can be easily installed, and a zipper 5 with a stop bar and a zipper product 1 with good workability can be provided.

[0085] Furthermore, as a variation of the above-described embodiment, the storage chain tooth 40B can also be as follows: Figure 9As shown, it is configured as follows. Specifically, the receiving tooth 40B has a partial cylindrical surface 47 formed throughout the engagement portion 42, i.e., the front engagement head 43b and the back engagement head 44c, relative to the shape of the engaging tooth 40A. This partial cylindrical surface 47 is used to form a through hole 51A in the front and back directions. Therefore, the partial cylindrical surfaces 47 of adjacent receiving teeth 40B form through holes 51A through which the protrusion 73 can pass. In addition, the lowermost receiving tooth 40B is a receiving tooth 40B6 with the same shape as the engaging tooth 40A.

[0086] In this case, similarly, the front member 71 and the back member 81 constituting the stop bar 70 are installed relative to the receiving teeth 40B of the left and right pair of chain teeth members 10, so that the two protrusions 73 of the front member 71 pass through the through holes 51A formed between the adjacent receiving teeth 40B5 and through the hole portion 83 of the back member 81.

[0087] Furthermore, similar to the above embodiment, a riveting flange 77 is formed by riveting the top end of the riveting protrusion 73, thereby fixing the front member 71 and the back member 81 to each other to form a stop bar 70.

[0088] Furthermore, the through hole 51A formed by the partial cylindrical surfaces 47, 47 of the adjacent receiving chain teeth 40B can be formed into a cylindrical shape without gaps, but it can also have a small gap between the partial cylindrical surfaces 47, 47.

[0089] In this case, similarly, the inner diameter of the through hole 51A is slightly larger than the outer diameter of the protrusion 73, so as to prevent the protrusion 73 from being bent when riveting the top part of the protrusion 73, which is fitted into the through hole 51A that houses the chain teeth 40B1.

[0090] Furthermore, in the above embodiments, clothing was described as a zipper product, but the zipper product of this utility model is not limited to clothing, but includes various products such as shoes, bags and other daily necessities, industrial materials, and various seats for automobiles, trains, aircraft, etc.

[0091] Furthermore, this utility model is not limited to the above-described embodiments, but can be appropriately modified or improved within the scope of implementation.

[0092] In the above embodiments, the case where the stop bar is installed at the lower end of the chain tooth row is described. However, the stop bar of this utility model can be installed at least a part of the chain tooth row. It can be installed at the upper end of the chain tooth row or in the middle of the chain tooth row.

[0093] In addition, in the above embodiment, the protrusion is formed on the front side member and the hole is formed on the back side member, but the present invention is not limited to this. Alternatively, the protrusion may be formed on the back side member and the hole may be formed on the front side member.

[0094] Furthermore, in the above embodiment, the structure is designed with two protrusions on the front member and two holes on the back member. However, the present invention is not limited to this; any structure with at least one protrusion and at least one hole is acceptable. Alternatively, the structure may have both a protrusion and a hole on both the front member and the back member.

[0095] Furthermore, in the above embodiment, the front and back components are fixed to each other by riveting the top end of the protrusion and engaging the riveting flange with the recess. However, this invention is not limited to this; other methods of fixing the protrusion can be used to fix the front and back components to each other. For example, the top end of the protrusion can be pressed into the hole, the top end of the protrusion can be fixed to the periphery of the hole using an adhesive, or the top end of the protrusion can be fixed to the periphery of the hole using ultrasonic welding.
