Description

Technical Field

[0001] This invention relates to a zipper opening insert and a zipper having the opening insert. Background Technology

[0002] Generally speaking, a zipper has: a pair of left and right zipper teeth, which have multiple zipper teeth installed on the side edges of the strip-shaped zipper teeth to form a tooth row; and a slidable zipper pull, which is installed in a slidable manner on the tooth row of the left and right zipper teeth.

[0003] In addition, to allow the left and right zipper teeth to pull apart when the left and right zipper teeth are separated, a zipper release insert is sometimes provided on the zipper. Generally, this zipper release insert has: an insert bar, which is fixed to the zipper tape adjacent to the zipper teeth of one zipper tooth; a base bar, which is fixed to the zipper tape adjacent to the zipper teeth of another zipper tooth; and a base body, which is integrally provided at the top end of the base bar. Furthermore, the base body is provided with an insert bar storage portion (insert bar storage hole) for inserting and storing the insert bar.

[0004] On the other hand, for example, Japanese Patent Application Publication No. 2022-38070 (Patent Document 1) describes a product with a zipper that forms a zipper without using a zipper tape.

[0005] The zippered product of Patent Document 1 comprises: a first zipper tooth component, which is formed by mounting multiple zipper teeth and inserts on a rope-like fixing component; and a second zipper tooth component, which is formed by mounting multiple zipper teeth and a seat bar on a rope-like fixing component. These first and second zipper tooth components are sewn directly onto the zipper mounting component of clothing or similar fabric using a sewing machine, and a zipper pull is installed in the zipper tooth rows of the first and second zipper tooth components, thereby forming a zippered product.

[0006] Furthermore, the zippered product in Patent Document 1 includes an opening / closing insert comprising: an insert rod disposed to a first zipper tooth member; a seat rod disposed to a second zipper tooth member; and a seat body mounted on the seat rod of the second zipper tooth member after the second zipper tooth member is sewn onto the zipper mounting member. Additionally, to sew the insert rod onto the zipper mounting member, the insert rod of the first zipper tooth member has a first fin portion extending outward from the insert rod in the width direction. To sew the seat rod onto the zipper mounting member, the seat rod of the second zipper tooth member has a second fin portion extending outward from the seat rod in the width direction.

[0007] In the opening and closing insert of Patent Document 1, in order to install the base body onto the base rod, a locking recess is provided that is recessed from the lower surface of the base rod toward the upper side. In addition, the base body has: an upper wall portion that covers a portion of the upper surface of the base rod and a portion of the upper surface of the insert rod; and a lower wall portion that covers a portion of the lower surface of the base rod and a portion of the lower surface of the insert rod. The lower wall portion of the base body is provided with: an elastic claw portion that protrudes from the lower wall portion toward the base rod storage portion (base rod storage space) of the base body and engages with the locking recess of the base rod; a through hole portion that is provided to the left and right sides and the rear side of the elastic claw portion through the lower wall portion; and a space portion that allows the elastic deformation of the elastic claw portion on the lower side of the elastic claw portion.

[0008] In the opening and closing insert of Patent Document 1, when installing the seat body to the seat bar of the second chain tooth member, the seat bar is inserted into the seat bar storage portion of the seat body from the front side, and is pressed deeply into the seat bar storage portion. By pressing the seat bar into the seat bar storage portion of the seat body in this way, the elastic claw portion of the seat body is first pressed by the seat body, and the seat bar storage portion of the seat body is elastically deformed in such a way that the seat bar storage portion of the seat body opens.

[0009] Next, the base bar is pressed further into the base bar receiving portion of the base body, causing the engaging recess of the base bar to move further inward (rearward) than the position of the elastic claw portion of the base body, releasing the pressure from the base bar on the elastic claw portion. As a result, the elastic claw portion elastically returns to its original shape and inserts into the engaging recess of the base bar, thus enabling the elastic claw portion of the base body to engage with the engaging recess of the base bar. This allows the base body to be mounted and held in place by the base bar of the second chain tooth member.

[0010] The zippered product described in Patent Document 1 can function as a zipper without using a zipper tape, thus achieving effects such as reduced manufacturing costs, lighter clothing, and improved clothing softness. Furthermore, the zippered product in Patent Document 1 has an opening / closing insert formed by a base bar, a base body, and an insert bar. Therefore, when the teeth of the first and second zipper teeth are separated, the component with the first zipper tooth sewn onto it and the component with the second zipper tooth sewn onto it can be easily opened.

[0013] Patent Document 1: Japanese Patent Application Publication No. 2022-38070 Summary of the Invention

[0014] The problem the invention aims to solve

[0015] In the zippered product of Patent Document 1, when installing the seat body to the seat bar of the second chain tooth member, it is necessary to insert and press the seat bar into the seat bar storage part of the seat body, so that the elastic claw part provided on the lower wall of the seat body is elastically deformed.

[0016] However, when the base rod of Patent Document 1 is inserted into the base rod storage part of the base body, if the insertion direction of the base rod is tilted relative to the insertion direction into the base body, or if the insertion posture of the base rod is tilted in a distorted manner relative to the base rod storage part of the base body, a large stress is easily applied to the elastic claw part of the base body, and the elastic claw part sometimes breaks and is damaged.

[0017] Furthermore, after the base bar is inserted into the base bar storage portion of the base body and the base body is installed onto the base bar, for example, due to the base bar of the second chain tooth member being pulled away from the base body, a pulling force along the zipper length direction is sometimes applied to the base bar, causing the base bar to be pulled out of the base body. In the following explanation, the pulling force along the zipper length direction applied to the base bar due to such pulling is referred to as longitudinal tension.

[0018] In conventional zippered products like Patent Document 1, when a longitudinal tensile force is applied to the base bar, the base bar storage portion of the base bar may sometimes be open in the thickness direction (height direction) of the base bar due to the material of the base body. In this case, it is considered that the engagement between the elastic claw portion of the base bar and the engaging recess of the base bar may easily disengage, which may result in a reduction in the strength of the opening insert against the longitudinal tensile force.

[0019] The present invention was made in view of the above-mentioned problems, and its object is to provide a zipper with the opening and closing insert that makes it difficult to cause damage to the locking claw when the seat is installed on the seat bar by utilizing the elastic force of the locking claw.

[0020] Solution for solving the problem

[0021] To achieve the above objectives, the opening / closing insert provided by the present invention comprises: a base rod; a base body mounted on the base rod; and a plug rod inserted into or removed from the base body. The base body comprises: a base body main body portion; a base rod receiving portion disposed in the base body main body portion and for receiving the base rod; and a plug rod receiving portion disposed in the base body main body portion and for inserting and removing the plug rod. The base body main body portion comprises: a first wall portion covering a portion of a first surface of both the base rod and the plug rod; a second wall portion covering a portion of a second surface of both the base rod and the plug rod; a partition portion disposed between the plug rod receiving portion and the base rod receiving portion and connecting the first wall portion and the second wall portion; and an engaging claw portion extending from the partition portion toward the base rod receiving portion and, at least partially, capable of engaging. The base has elastic deformation; and a protrusion that protrudes from the first wall or the second wall toward the base rod receiving portion and extends along the insertion direction of the base rod relative to the base body. The base rod has: a base rod body portion having an elongated shape in the insertion direction; a locking recess recessed in the opposite side of the base rod body portion opposite to the insert rod; and a receiving groove portion recessed in the base rod body portion along the insertion direction. The protrusion of the base body is received in the receiving groove portion of the base rod. The base rod has an overlapping portion where the forming range of the locking recess in the insertion direction overlaps with the forming range of the receiving groove portion in the insertion direction. By engaging the locking claw portion of the base body with the locking recess portion of the base rod, the movement of the base rod in the direction of being pulled out relative to the base body is restricted.

[0022] In the opening and closing insert of the present invention, preferably, the engaging claw portion has: a claw body portion; a first claw end portion extending from the claw body portion toward the first wall portion of the seat; and a second claw end portion extending from the claw body portion toward the second wall portion of the seat, wherein the first claw end portion and the second claw end portion are respectively provided with chamfer portions such that the size of the engaging claw portion in the width direction of the seat portion decreases toward the first wall portion or the second wall portion.

[0023] Furthermore, according to the present invention, a zipper having the above-described opening and closing insert is provided.

[0024] The effects of the invention

[0025] According to the present invention, when the seat body is installed on the seat bar using the elastic force of the engaging claw portion, it is difficult to cause damage to the engaging claw portion. Attached Figure Description

Detailed Implementation

[0036] The following are examples and references to the appendix. Figure 1 The preferred embodiments of the present invention will be described below.

[0037]

Example

[0038] Figure 1 This is a schematic diagram showing the main parts of a zippered product (clothing) having the opening and closing insert of this embodiment. Figure 2 This is a schematic bottom view of the base rod and insert rod in this embodiment. Figure 3It is a bottom view schematically showing the cross-section of the seat in the open-end insert, together with the configuration of the seat and insert.

[0039] Furthermore, in the following explanation, the forward / backward direction refers to the length direction of the first and second chain teeth members or the length direction of the zipper along the sliding direction of the zipper pull. Alternatively, the forward / backward direction can also be referred to as the direction of the first and second chain teeth members along the fixing member. In this case, the direction in which the zipper pull slides to engage the left and right chain teeth is defined as forward, and the direction in which the zipper pull slides to disengage the left and right chain teeth is defined as backward.

[0040] The left-right direction refers to the direction along the width of the zipper or the direction in which the first and second zipper teeth approach or move away from each other. Alternatively, the left-right direction can be described as a direction orthogonal to the sliding direction of the zipper pull and parallel to the surface and back of the fabric that serves as the zipper mounting component. In this case, the inner side of the left-right or width direction refers to the direction in which the left and right zipper teeth approach each other, and the outer side of the left-right or width direction refers to the direction in which the left and right zipper teeth move away from each other.

[0041] The up-down direction refers to the direction orthogonal to the front-back and left-right directions, or the direction orthogonal to the surface and back of the fabric that serves as the component for mounting the zipper. In this case, the orientation on the outer surface of the fabric when the garment is manufactured is defined as up, and the orientation on the opposite side of that up is defined as down. Furthermore, for the zipper insert, the insertion direction of the insert or base is the downward or approximately downward direction in the up-down direction of the base.

[0042] Furthermore, specifically in this embodiment, the front-to-back direction is... Figure 1 The vertical direction and the horizontal direction on the paper are... Figure 1 The left-right direction on the paper. The up-down direction is... Figure 1 The reverse side of the paper. In this case, the top is... Figure 1 The paper's front and back sides are facing downwards. Figure 1 The orientation of the inside of the paper.

[0043] The zippered product 1 of this embodiment is a garment 1 with a zipper 2, and the zipper 2 is formed on the placket of the front of the garment 1. The zippered product 1 has: a pair of left and right zipper tooth straps 5, which form a tooth row 7 by directly sewing the tooth members 10 to the fabric 6 of the garment 1; a zipper pull 60, which is slidably mounted to the tooth rows 7 of the left and right zipper tooth straps 5; and an opening insert 20, which is disposed adjacent to the lower end of the left and right tooth rows 7.

[0044] In this case, the fabric 6 forming the garment 1 is a zipper mounting component for mounting the zipper tooth component 10. Therefore, in the zippered garment 1 of this embodiment, the zipper 2 is formed without using a zipper tape. The opening and closing insert 20 has a base bar 30, a base body 40, and an insert bar 50.

[0045] Each of the left and right zipper pull portions 5 has a fabric 6 for mounting the zipper and a zipper tooth member 10 mounted on the fabric 6. In this case, the zipper tooth member 10 has a front view of the zippered garment 1 viewed from above (for example, see reference). Figure 1 The first chain tooth member 10a is located on the right side and the second chain tooth member 10b is located on the left side. The first chain tooth member 10a and the second chain tooth member 10b are arranged vertically along the front-back direction, and are also arranged opposite each other in the width direction.

[0046] The first zipper tooth component 10a has: a rope-like fixing member 11; a plurality of zipper teeth 12 installed at certain intervals in the front-back direction on the fixing member 11; a base bar 30 installed at the rear end of the fixing member 11; and a base body 40 assembled to the base bar 30. The second zipper tooth component 10b has: a rope-like fixing member 11; a plurality of zipper teeth 12 installed at certain intervals in the front-back direction on the fixing member 11; and a plug bar 50 installed at the rear end of the fixing member 11.

[0047] Each row of zipper teeth 7 on the left and right sides of the zipper tooth belt 5 is formed by a plurality of zipper teeth 12 sewn onto the first zipper tooth member 10a or the second zipper tooth member 10b of the fabric 6.

[0048] The fixing members 11 of the first chain tooth member 10a and the second chain tooth member 10b are relatively long in the front-to-back direction and are flexible. Furthermore, the fixing member 11 is formed of a slender member with a generally circular cross-section orthogonal to the length direction. The fixing member 11 uses a rope (also called a braided thread) formed by wrapping a core yarn composed of, for example, monofilaments, ply yarns (braids), or multiple multifilaments after being combined with knitted yarn around a pocket weave portion.

[0049] The zipper teeth 12 of each of the first zipper tooth members 10a and 10b are formed substantially the same as those described in the aforementioned Patent Document 1. To put it simply, each zipper tooth 12 has a shape that is separate from and independent of the zipper teeth 12 adjacent to it in the front-back direction, and is formed by injection molding a thermoplastic resin such as polyaldehyde onto the fixing member 11.

[0050] Each zipper tooth 12 has: a tooth body portion fixed to the fixing member 11; a tooth neck portion having a shape that extends inward from the tooth body portion in the width direction and is necked; an engagement head portion extending further inward from the tooth neck portion in the width direction and having a generally elongated oval shape when viewed from above; and a pair of front and rear shoulders portioning forward and backward from the tooth neck portion.

[0051] The seat bar 30 forming the opening and closing insert 20 is fixed to the fixing member 11 by injection molding thermoplastic resin onto the fixing member 11 of the first chain tooth member 10a. The seat bar 30 has: a seat bar body portion 31, which is fixed to the fixing member 11 and has a shape that is longer in the front-rear direction; and a seat side fin portion 39, which extends outward from the seat bar body portion 31 in the left-right direction.

[0052] The main body 31 of the base rod has a generally rectangular shape, and the fixing member 11 is enclosed inside it. In addition, the main body 31 of the base rod has: an upper surface and a lower surface facing in the vertical direction; an opposing side (inner side) 31a facing inward in the width direction and opposite to the insert rod 50; and an outer side facing outward in the width direction, and is connected to the base side fin portion 39.

[0053] like Figure 1 and Figure 2 As shown, the main body 31 of the base rod has: a locking recess 32 recessed in the opposite side 31a of the main body 31; a first seat side protrusion 33 and a second seat side protrusion 34 protruding from the upper half of the main body 31 toward the inside in the width direction; a third seat side protrusion 35 and a fourth seat side protrusion 36 protruding from the lower half of the main body 31 toward the inside in the width direction; and a receiving groove 37 and an auxiliary groove 38 recessed in the lower surface of the main body 31.

[0054] The engaging recess 32 of the base rod body 31 has a shape for engaging the base 40 (described later) to accommodate the base 40. Specifically, the engaging recess 32 is disposed in the rear half of the base rod body 31 and is recessed outward in the width direction from the opposite side 31a of the base rod body 31. Furthermore, the rear half of the base rod body 31 refers to the portion disposed in the base rod body 31 that is located rearward from the center portion in the front-rear direction of the base rod body 31. In this embodiment, the engaging recess 32 has: an engaging surface 32a disposed along the width direction and facing forward; and a curved surface 32b that bends forward from the outer side of the engaging surface 32a in the width direction and connects to the opposite side 31a of the base rod body 31.

[0055] The first side protrusion 33 and the second side protrusion 34 are arranged separately from each other in the front-rear direction, and are sized to contact the main body 51 of the insert 50 (described later) when the insert 50 is housed in the base 40. The first side protrusion 33 is positioned forward of the second side protrusion 34 and has a shape that engages with the chain tooth engagement portion 52 (described later) of the insert 50. The third side protrusion 35 and the fourth side protrusion 36 are respectively disposed below the first side protrusion 33 and the second side protrusion 34. A space is provided between the third side protrusion 35 and the fourth side protrusion 36 for the insert 50's side protrusion 54 to be inserted when the insert 50 is housed in the base 40.

[0056] like Figure 2 As shown, the receiving groove 37 of the main body portion 31 is recessed into the lower surface of the rear half of the main body portion 31 from the rear end edge toward the front. The receiving groove 37 opens at the rear end edge of the main body portion 31 and is formed in a straight line along the front-rear direction.

[0057] The receiving groove 37 can be guided in such a way that when the base rod 30 is inserted into the base rod receiving part 42 of the base body 40 and the base body 40 is assembled to the base rod 30 as will be discussed later, the protrusion 46 of the base body 40 is inserted from the rear end edge of the base rod body 31, so that the base rod 30 is inserted straight into the base body 40.

[0058] Furthermore, when the seat rod 30 is assembled with the seat body 40, the protrusion 46 of the seat body 40 is received in the receiving groove 37 of the seat rod 30, thereby making it difficult for the seat rod 30 to move relative to the seat body 40 in the width direction. In particular, in this embodiment, there is an overlapping portion 25 (see reference) in the front-rear direction where the forming range of the engaging recess 32 of the seat rod 30 and the forming range of the receiving groove 37 of the seat rod 30 overlap. Figure 2 Therefore, it is possible to effectively prevent or suppress the wobbling of the base bar 30 relative to the base body 40 (especially wobbling in the width direction). In addition, it is possible to prevent the engaging claw portion 45 of the base body 40, which is engaged with the engaging recess 32 of the base bar 30, from being pulled out of the engaging recess 32 of the base bar 30 and disengaging.

[0059] The auxiliary groove 38 and the receiving groove 37 are integrally recessed into the rear end (top end) of the base rod body 31. Furthermore, the auxiliary groove 38 is formed from the rear end of the receiving groove 37 toward the inward side in the width direction (in other words, toward the direction close to the insert rod 50), and it opens at the rear end edge of the base rod body 31. Additionally, when the base body 40 is assembled to the base rod 30, the auxiliary protrusion 47 of the base body 40 is housed in the auxiliary groove 38.

[0060] The fin portion 39 is connected to the central portion of the base rod body 31 in the vertical direction on the outer side of the base rod body 31. The fin portion 39 has: a flat fin body 39a that extends outward from the base rod body 31 in the width direction; a notch 39b that is provided at the front end of the fin body 39a; two hanging wire portions 39c that protrude from the fin body 39a in the oblique forward and oblique rear directions; and three openings 39d that penetrate the fin body 39a in the front-back direction.

[0061] The opening 39d of the seat-side fin portion 39 is provided so that the sewing needle of the sewing machine can pass through during the sewing process of the seat bar 30 and the fabric (the component for mounting the zipper) 6. During this sewing process, when the seat bar 30 is sewn onto the fabric 6, the sewing needle passes through, for example, in… Figure 1 The position indicated by the imaginary circle in the middle rises and falls in the vertical direction to form a sewing part (stitch) 8, and the base bar 30 is fixed to the fabric 6 by means of this sewing part 8. At this time, by providing a thread hanging part 39c on the fin part 39 on the base side, the base bar 30 can be reliably fixed to the fabric 6, and the position of the base bar 30 fixed to the fabric 6 is less likely to deviate.

[0062] Furthermore, in this invention, the shape and size of the seat-side fin portion 39 are not particularly limited and can be changed as needed.

[0063] The base 40, forming the opening and closing insert 20, is mounted and fixed to the lower end of the base rod 30. In this embodiment, the base 40 has: a base body portion 41 having a generally rectangular shape; and a base rod storage portion 42 and a rod storage portion 43, which have openings on the front surface of the base body portion 41, and whose internal space extends rearward. The base rod 30 is inserted into and stored in the base rod storage portion 42. The rod 50 is inserted into the rod storage portion 43 in a removable manner.

[0064] The main body 41 of the seat body 40 has: an upper wall portion (first wall portion) 41a and a lower wall portion (second wall portion) 41b, which are arranged opposite each other in the vertical direction; left and right side wall portions 41c, which connect the side edge portion of the upper wall portion 41a and the side edge portion of the lower wall portion 41b; and a rear wall portion 41d, which connects the rear end portion of the upper wall portion 41a and the rear end portion of the lower wall portion 41b.

[0065] The main body 41 of the seat has: a partition 44 that connects the upper wall 41a and the lower wall 41b at a position between the seat rod storage part 42 and the insert rod storage part 43; a locking claw 45 that extends from the partition 44 toward the seat rod storage part 42 and is at least partially elastically deformable; and a protrusion 46 and an auxiliary protrusion 47 that protrude from the lower wall 41b toward the seat rod storage part 42.

[0066] Furthermore, the main body 41 of the seat has: left and right slits 41e, which are provided on the left and right sidewalls 41c of the main body 41 of the seat, through which the seat-side fin portion 39 or the insert rod-side fin portion 59 (described later) of the insert rod 50 passes; and a communicating hole 48, which opens in the rear wall portion 41d, and the internal space extends forward. In this case, the right slit 41e communicates with the seat rod storage portion 42 of the seat 40, and the left slit 41e communicates with the insert rod storage portion 43 of the seat 40. The communicating hole 48 communicates with both the seat rod storage portion 42 and the insert rod storage portion 43.

[0067] The upper wall portion 41a and the lower wall portion 41b of the main body portion 41 are arranged orthogonally (or substantially orthogonally) to the vertical direction. The upper wall portion 41a covers the upper surface of at least the lower end of the base rod 30 and the upper surface of at least the lower end of the insertion rod 50 inserted into the insertion rod receiving portion 43. The lower wall portion 41b covers the lower surface of at least the lower end of the base rod 30 and the lower surface of at least the lower end of the insertion rod 50.

[0068] For example, Figure 5 As shown, the upper wall portion 41a of the main body portion 41 has: left and right thick-walled upper wall portions 41f, which form the inner wall surfaces of the seat rod receiving portion 42 and the insert rod receiving portion 43; and thin-walled upper wall portions 41g, which are formed at a position closer to the inside in the width direction than the thick-walled upper wall portions 41f, and are thinner than the thick-walled upper wall portions 41f. The lower wall portion 41b of the main body portion 41 also has, similarly to the upper wall portion 41a,: left and right thick-walled lower wall portions 41h; and thin-walled lower wall portions 41i, which are formed at a position closer to the inside in the width direction than the thick-walled lower wall portions 41h, and are thinner than the thick-walled lower wall portions 41h.

[0069] By arranging a thin-walled upper wall portion 41g and a thin-walled lower wall portion 41i at the central portion in the width direction of the seat body 40, the engaging claw portion 45 can ensure an appropriate height dimension (vertical dimension) in the vertical direction. Therefore, the engaging claw portion 45 can stably engage with the engaging recess 32 of the seat rod 30. Furthermore, spaces can be provided between the upper wall portion 41a (thin-walled upper wall portion 41g) of the seat body 41 and the engaging claw portion 45, and between the lower wall portion 41b (thin-walled lower wall portion 41i) of the seat body 41 and the engaging claw portion 45. Therefore, the engaging claw portion 45 can appropriately elastically deform without interfering with the upper wall portion 41a and the lower wall portion 41b, as will be discussed later.

[0070] For example, Figure 3As shown, the partition 44 of the seat body 40 is positioned slightly rearward relative to the front surface of the main body 41. The partition 44 is formed as a column along the vertical direction with a cross section that is approximately quadrilateral to the vertical direction, and is connected to the upper wall portion 41a (thin-walled upper wall portion 41g) and the lower wall portion 41b (thin-walled lower wall portion 41i).

[0071] The engaging claw portion 45 of the seat body 40 extends obliquely to the right and rear, protruding from the lower end of the partition portion 44 toward the seat rod storage portion 42. In addition, the engaging claw portion 45 is separately disposed from the upper wall portion 41a and the lower wall portion 41b of the seat body 40.

[0072] The engaging claw portion 45 of this embodiment has: a first claw side surface (claw right side surface) 45a, which has a cross section orthogonal to the vertical direction when viewed at the center position in the vertical direction of the engaging claw portion 45. Figure 3 When the first claw side surface 45a is positioned, it extends obliquely to the right rearward from the right side of the partition 44 opposite to the seat rod 30 via a bend; the second claw side surface (claw left side surface) 45b extends obliquely to the right rearward from the left side of the partition 44 opposite to the insert rod 50 via a bend; and the claw rear end surface 45c is disposed between the rear end of the first claw side surface 45a and the rear end of the second claw side surface 45b in a rearward manner. In addition, a tip edge (rear end edge) 45d formed with an acute angle is disposed between the first claw side surface 45a and the claw rear end surface 45c.

[0073] The first claw side surface 45a of the engaging claw portion 45 is in the cross section ( Figure 3 The locking claw 45 extends straight down and to the right from the partition 44 and enters the rod storage portion 42 of the seat body 40. When the rod 30 is inserted from the front of the seat body 40 and pressed into the rod storage portion 42, the first claw side 45a of the locking claw 45 contacts the top (lower end) of the rod body 31 and further receives pressing pressure from the rod body 31. As a result, the locking claw 45 elastically deforms in such a way that the top edge 45d of the locking claw 45 moves closer to the rod storage portion 43 and contacts the opposite side (inner side) 31a of the rod body 31.

[0074] Then, the base bar 30 is pressed rearward while contacting the top edge 45d of the engaging claw portion 45 with the opposite side 31a of the base bar body portion 31, so that the engaging recess 32 of the base bar 30 reaches the position of the top edge 45d of the engaging claw portion 45. As a result, the pressing of the base bar 30 on the engaging claw portion 45 is released, and the engaging claw portion 45 elastically returns to its original shape. Therefore, the engaging claw portion 45 can be inserted into the engaging recess 32 of the base bar 30 and engaged with the engaging recess 32.

[0075] The second claw side 45b of the engaging claw part 45 is in Figure 3The cross-section is formed in a shape that is bent or folded inwards from the central part or the nearby part of the engaging claw 45 in the front-rear direction. By forming the second claw side surface 45b in this way, the engaging claw 45 can be easily elastically deformed when the engaging claw 45 is pressed by the seat bar body part 31.

[0076] When the engaging claw portion 45 engages with the engaging recess 32 of the base rod 30, the rear end face 45c of the claw portion 45 contacts the engaging surface 32a of the engaging recess 32. Therefore, for example, when the base body 40 mounted to the base rod 30 is pulled backward, the rearward movement of the base body 40 relative to the base rod 30 can be restricted, thus making it difficult for the base body 40 to detach from the base rod 30.

[0077] For example, Figure 4 and Figure 5 As shown, the engaging claw portion 45 of this embodiment has the following in the vertical direction: a claw body portion 45e, which is disposed in the central portion in the vertical direction; an upper claw end portion (first claw end portion) 45f, which extends from the claw body portion 45e toward the upper wall portion 41a of the seat body 40; and a lower claw end portion (second claw end portion) 45g, which extends from the claw body portion 45e toward the lower wall portion 41b of the seat body 40.

[0078] A chamfered portion 45h is provided at the upper end 45f of the engaging claw portion 45, such that the dimension of the engaging claw portion 45 in the left-right direction decreases toward the upper wall portion 41a of the base body 40. Additionally, a chamfered portion 45h is also provided at the lower end 45g of the engaging claw portion 45, such that the dimension of the engaging claw portion 45 in the left-right direction decreases toward the lower wall portion 41b of the base body 40.

[0079] In this case, the chamfered portion 45h, provided at the upper end 45f and the lower end 45g of the claw, is disposed on the second claw side surface (left side surface of the claw) 45b of the engaging claw portion 45 facing the insert rod receiving portion 43. In addition, the chamfered portion 45h is continuously formed on the entire engaging claw portion 45 from the base end of the engaging claw portion 45 connected to the partition portion 44 to the top end of the engaging claw portion 45 that contacts the engaging recess 32 of the seat rod 30.

[0080] By providing the chamfered portion 45h as described above in the engaging claw portion 45 of this embodiment, when the engaging claw portion 45 is elastically deformed by being pressed by the main body portion 31 as described above, the stress applied to the upper end portion 45f and the lower end portion 45g of the claw can be reduced. Therefore, the engaging claw portion 45 can be easily elastically deformed, and furthermore, it is difficult for the engaging claw portion 45 to break or suffer other damage during elastic deformation.

[0081] The protruding rib 46 and auxiliary protruding rib 47 of the seat body 40 are provided on the lower wall portion 41b (especially the thick-walled lower wall portion 41h) of the seat body 40 in an upwardly projecting manner. In this case, the height dimension (vertical dimension) of the protruding rib 46 measured from the thick-walled lower wall portion 41h and the height dimension (vertical dimension) of the auxiliary protruding rib 47 measured from the thick-walled lower wall portion 41h are the same size.

[0082] The protrusion 46 is formed in a straight line along the front-to-back direction. The protrusion 46 is inserted into and housed in the receiving groove 37 of the base rod 30.

[0083] For example, in the past, when the retaining bar with the chain teeth sewn to the fabric was inserted into the retaining bar storage part of the retaining body while deforming the elastic claw, as mentioned above, the elastic claw sometimes broke and was damaged. The cause of the damage was investigated and it was found that, in the past, when the retaining bar was inserted into the retaining bar storage part of the retaining body, due to the influence of the fabric with the chain teeth sewn to it, the retaining bar sometimes tilted relative to the front-back direction, and the insertion posture of the retaining bar was distorted. As a result, when the retaining bar was used to elastically deform the engaging claw, sometimes the engaging claw was excessively elastically deformed, and inappropriate force (unreasonable force) was applied to the engaging claw.

[0084] In contrast, in this embodiment, when the base rod 30 is inserted and pressed into the base rod receiving portion 42 of the base body 40, the protrusion 46 of the base body 40 is inserted into the receiving groove 37 already provided to the base rod 30. This allows the protrusion 46 of the base body 40 to guide the insertion of the base rod 30, thereby facilitating the insertion of the base rod 30 straight relative to the base body 40 in the front-back direction. Especially in this embodiment, as described above, the overlapping portion 25, where the forming range of the engaging recess 32 on the base rod 30 overlaps with the forming range of the receiving groove 37 on the base rod 30, allows the protrusion 46 of the base body 40 to be inserted into the receiving groove 37 of the base rod 30 before the base rod 30 contacts the engaging claw portion 45 of the base body 40, thus initiating the guidance of the base rod 30 by the protrusion 46.

[0085] Therefore, in this embodiment, when the seat rod 30 is pressed into the receiving groove 37 while the locking claw portion 45 is elastically deformed by the seat rod 30, the seat rod 30 is less likely to tilt relative to the front-back direction. In addition, the insertion posture of the seat rod 30 is less likely to be distorted. Thus, excessive elastic deformation of the locking claw portion 45 and improper force applied to the locking claw portion 45 by the seat rod 30 can be prevented or suppressed, making it difficult for adverse situations such as damage to the locking claw portion 45 to occur.

[0086] In this embodiment, the auxiliary protrusion 47 is integrally formed with the protrusion 46, and extends from the protrusion 46 toward the inner side in the width direction (in other words, from the protrusion 46 toward the direction approaching the insertion rod storage portion 43). The auxiliary protrusion 47 is located in... Figure 3 The cross-section is formed into a triangle (especially a right triangle), and the width dimension (the dimension in the left-right direction) of the auxiliary protrusion 47 decreases towards the rear. Furthermore, in this invention, the protrusion 46 and auxiliary protrusion 47 of the seat body 40 may also be provided in a downwardly projecting manner on the upper wall portion 41a of the seat body 40. In this case, the receiving groove portion 37 and auxiliary groove portion 38 of the seat rod 30 are also recessed into the upper surface of the seat rod body portion 31.

[0087] The insert 50 forming the opening and closing insert 20 is fixed to the fixing member 11 by injection molding thermoplastic resin onto the fixing member 11 of the second chain tooth member 10b. The insert 50 has: an insert body portion 51 having a shape that is longer in the front-rear direction; a chain tooth engaging portion 52 that protrudes from the front end of the insert body portion 51 toward the inner side in the width direction; and an insert side fin portion 59 that extends from the insert body portion 51 toward the outer side in the left-right direction.

[0088] The insert body 51 has a generally rectangular parallelepiped shape and is longer than the base body 31 in the front-rear direction. The insert body 51 also encloses the fixing member 11 inside. In this embodiment, the insert body 51 has: an upper surface and a lower surface facing in the vertical direction; an opposing side surface facing inward in the width direction opposite to the insert 50; and an outer side surface facing outward in the width direction, for connection to the insert side fin portion 59.

[0089] like Figure 1 and Figure 2 As shown, the insert rod body 51 has: an inner step portion 53, which is provided on the opposite side of the base rod body 31; and an insert rod side protrusion portion 54, which protrudes from the lower half of the base rod body 31 in the width direction inward. The inner step portion 53 of the insert rod body 51 has: a first step portion 53a, which is formed on the opposite side of the base rod body 31 in the front-rear direction; and a second step portion 53b, which is disposed below the first step portion 53a. The insert rod side protrusion portion 54 is shown in, for example, the bottom view of the insert rod 50 (…). Figure 2 It has a roughly trapezoidal shape and is positioned further back than the chain tooth engagement part 52.

[0090] In this embodiment, for example, when the insertion rod 50 is inserted into and held in the insertion rod storage portion 43 of the base 40 (see reference 43) Figure 1The first seat side protrusion 33 of the seat rod 30 contacts the first step 53a of the insert rod body 51, and the second seat side protrusion 34 of the seat rod 30 contacts the second step 53b of the insert rod body 51. Furthermore, the insert rod side protrusion 54 of the insert rod body 51 is inserted between the third seat side protrusion 35 and the fourth seat side protrusion 36 of the seat rod 30 (see reference). Figure 2 ).

[0091] In the insert bar 50 of this embodiment, the upper half and lower half of the zipper tooth engaging portion 52 have asymmetrical shapes in the vertical direction. The upper half of the zipper tooth engaging portion 52 has a shape that engages with the zipper tooth 12 adjacent to the seat bar 30 on the same side as the first zipper tooth member 10a and the first seat side protrusion 33 provided to the seat bar 30.

[0092] The insert-side fin portion 59 is connected to the central portion of the insert-side main body portion 51 in the vertical direction on the outer side of the insert-side fin portion 51. The insert-side fin portion 59 has a shape that is symmetrical in the left-right direction with respect to the seat-side fin portion 39. Therefore, the insert-side fin portion 59 is described simply as follows: a flat fin body portion 59a that extends outward in the width direction from the insert-side main body portion 51; a notch portion 59b that is provided at the front end of the fin body portion 59a; two hanging wire portions 59c that protrude from the fin body portion 59a in the oblique forward and oblique rear directions; and three openings 59d that penetrate the fin body portion 59a in the front-back direction.

[0093] Furthermore, in this invention, the shape of the insert 50 is not particularly limited and can be changed as needed.

[0094] The zipper pull 60 of this embodiment is formed substantially the same as the zipper pull described in Patent Document 1. Briefly describing the zipper pull 60 of this embodiment, the zipper pull 60 of this embodiment has a zipper pull body 61 and a pull tab (not shown) held in the zipper pull body 61. The zipper pull body 61 has: an upper flange (not shown) and a lower flange 62; a connecting post 63 that connects the front end of the upper flange to the front end of the lower flange 62; left and right upper flange portions (not shown) that extend downward from the left and right side edges of the upper flange; left and right lower flange portions 64 that extend upward from the left and right side edges of the lower flange 62; and a pull tab mounting portion (not shown) that is vertically disposed on the upper surface of the upper flange.

[0095] The front end of the zipper head body 61 has left and right shoulder openings positioned on either side of the connecting post 63. The rear end of the zipper head body 61 has a rear opening. A roughly Y-shaped chain guide path connecting the left and right shoulder openings and the rear opening is formed between the upper and lower flanges 62 of the zipper head body 61. A through-gap is formed between the left and right upper flanges and the left and right lower flanges 64 of the zipper head body 61 for the fabric 6 to pass through.

[0096] The first chain tooth member 10a, equipped with the base bar 30 of this embodiment described above, and the second chain tooth member 10b, equipped with the insert bar 50, are sewn onto the fabric 6 forming the front of the garment 1. Next, the zipper head 60 is installed onto the chain tooth row 7 of the first chain tooth member 10a already installed on the fabric 6, and the base body 40 is assembled onto the base bar 30 on the side of the first chain tooth member 10a, thereby forming a zipper 2 equipped with the opening and closing insert 20.

[0097] Hereinafter, a method for manufacturing the zippered garment 1 of this embodiment will be specifically described.

[0098] First, the first zipper tooth component 10a and the second zipper tooth component 10b are manufactured. The first zipper tooth component 10a is manufactured by injection molding the aforementioned plurality of zipper teeth 12 and the base bar 30 into a rope-like fixing member 11. The second zipper tooth component 10b is manufactured by injection molding the aforementioned plurality of zipper teeth 12 and the insert bar 50 into a rope-like fixing member 11. In addition, the base body 40 is manufactured independently of the first zipper tooth component 10a and the second zipper tooth component 10b using injection molding.

[0099] Next, a sewing process is carried out in which the first chain tooth component 10a and the second chain tooth component 10b are respectively sewn to the side edge of the fabric 6 forming the garment 1.

[0100] In this sewing process, a serrated lockstitch sewing machine is used, and a sewing section 8 is formed on the surface and back of the fabric 6 using an upper thread (needle thread) and a lower thread (shuttle thread). The first chain tooth member 10a or the second chain tooth member 10b is then fixed to the fabric 6 using this sewing section 8. Furthermore, in this invention, the structure of the sewing machine and the sewing method performed by the sewing machine are not particularly limited.

[0101] After sewing the first chain tooth component 10a and the second chain tooth component 10b to the fabric 6 through the above-described sewing process, the zipper head installation process is carried out to install the zipper head 60 onto the chain tooth row 7 of the first chain tooth component 10a.

[0102] Next, a seat installation process is performed to install the seat body 40 onto the seat bar 30 on the side where the first chain tooth member 10a of the pull head 60 is installed. In this seat installation process, firstly, the seat body 40 is brought closer to the seat bar 30 from the rear side of the seat bar 30 on the side of the first chain tooth member 10a, for example, as... Figure 6 As shown, the top end (rear end) of the base rod 30 is inserted into the base rod storage portion 42 of the base body 40 from the front side. Thus, the base rod 30 is inserted into the base rod storage portion 42 of the base body 40, and the top end of the base rod 30 contacts the engaging claw portion 45 of the base body 40.

[0103] Furthermore, after the base rod 30 contacts the engaging claw portion 45 of the base body 40, the base rod 30 is pressed into the base rod storage portion 42 of the base body 40, thereby causing the engaging claw portion 45 of the base body 40 to elastically deform by pressing the base rod 30 against it. As a result, the internal space of the base rod storage portion 42, which was narrowed by the engaging claw portion 45, is opened, thus allowing the base rod 30 to move smoothly to the rear (inner side) of the base rod storage portion 42.

[0104] Furthermore, the engaging claw portion 45, while in an elastically deformed state, contacts the opposite side (inner side) 31a of the seat bar body 31 and approaches the engaging recess 32. Then, the engaging recess 32 of the seat bar 30 reaches the position of the top edge 45d of the engaging claw portion 45, thereby allowing the engaging claw portion 45 to elastically return to its original shape and engage with the engaging recess 32 of the seat bar 30.

[0105] Furthermore, in this embodiment, when the seat bar 30 on the first chain tooth member 10a side is inserted into the seat bar storage portion 42 of the seat body 40, for example, the protrusion 46 of the seat body 40 can be inserted and stored in the storage groove portion 37 provided on the lower surface of the seat bar body portion 31 before the seat bar 30 contacts the engaging claw portion 45 of the seat body 40. Thus, as described above, the seat bar 30 pressed into the seat body 40 can be guided by the protrusion 46 of the seat body 40, and therefore, the seat bar 30 can be easily inserted straight in the front-back direction into the storage groove portion 37 of the seat bar body portion 31.

[0106] As a result, it is possible to suppress the insertion orientation of the base rod 30 from tilting relative to the base body 40, and to prevent the insertion posture of the base rod 30 from becoming distorted, thus ensuring that the base rod 30 is smoothly and stably inserted into the base rod storage portion 42 of the base body 40. Furthermore, this allows the base rod 30 to appropriately and elastically deform the engaging claw portion 45 of the base body 40, thereby ensuring stable engagement between the engaging claw portion 45 of the base body 40 and the engaging recess 32 of the base rod 30. Moreover, it reduces the likelihood of defects such as breakage or damage to the engaging claw portion 45.

[0107] Furthermore, by pressing the base rod 30 into the base rod storage portion 42 of the base body 40 as described above, and engaging the locking claw portion 45 of the base body 40 with the locking recess 32, the base body 40 can be assembled and fixed to the base rod 30. This restricts the movement of the base rod 30 relative to the base body 40 in the direction of being pulled out from the base rod storage portion 42 of the base body 40.

[0108] Furthermore, with the zipper pull 60 in contact with the base 40, the insert bar 50 on the side of the second chain tooth member 10b is inserted from the left shoulder opening of the zipper pull 60 into the insert bar storage portion 43 of the base 40, thereby forming Figure 1 The example shown is an opening / closing insert 20 of this embodiment, which includes an insert 50, a base 30, and a base 40.

[0109] By performing the above-described process, a pair of front fabric parts are manufactured, each having a first zipper tooth component 10a and a second zipper tooth component 10b respectively installed. Then, the fabric parts are joined together using sewing or other methods to assemble the garment 1. Thus, a garment 1 equipped with a zipper 2 and an opening insert 20 is manufactured.

[0110] The zippered garment 1 of this embodiment, manufactured in this way, can function as a zipper 2 even without using a zipper tape. As a result, it is possible to reduce manufacturing costs, make the garment 1 lighter, and improve the softness of the garment 1.

[0111] Furthermore, an opening insert 20 is provided at the rear end of the zipper 2. Therefore, for example, when the zipper 2 is opened, the insert 50 of the first zipper tooth member 10a can be pulled out from the base 40, thereby making it easy to open the first zipper tooth member 10a and the second zipper tooth member 10b. In addition, the opened first zipper tooth member 10a and the second zipper tooth member 10b can be re-engaged, making it easy to close the zipper 2.

[0112] Furthermore, in the disengagement insert 20 of this embodiment, the seat body 40 is assembled to the seat rod 30 when the protrusion 46 of the seat body 40 is inserted into the receiving groove 37 of the seat rod 30. In particular, in this embodiment, an overlap portion 25 is provided where the forming range of the engaging recess 32 of the seat rod 30 and the forming range of the receiving groove 37 of the seat rod 30 overlap in the front-rear direction (see reference). Figure 2 This prevents the seat bar 30 from tilting within the seat bar storage portion 42 of the seat body 40 or from twisting its posture. Therefore, when using the zipper 2, the engaging claw portion 45 of the seat body 40 and the engaging recess 32 of the seat bar 30 can be stably maintained, preventing the engaging claw portion 45 from being pulled out of the engaging recess 32. In addition, it makes it less likely for the engaging claw portion 45 to break or become damaged.

[0113] Furthermore, in the zippered garment 1 of this embodiment, for example, when the base bar 30 on the side of the first zipper tooth member 10a is pulled forward to separate from the base body 40, a longitudinal pulling force is applied to the base bar 30 and the base body 40. Therefore, the base bar storage portion 42 of the base body 40 is prone to opening in the vertical direction. However, in the opening and closing insert 20 of this embodiment, the engaging claw portion 45 of the base body 40 is provided on the partition portion 44 and engages with the engaging recess 32 of the base bar 30 in the width direction. As a result, it is difficult for the engagement claw portion 45 of the base body 40 to disengage from the engaging recess 32 of the base bar 30 due to the base bar storage portion 42 opening in the vertical direction. Therefore, the strength of the opening and closing insert 20 against longitudinal pulling force can be improved.

[0114] Furthermore, in the above-described embodiments, a first tooth member 10a is formed by setting a base bar 30 and a base body 40 on a rope-shaped fixing member 11 to fix a plurality of zipper teeth 12, and a second tooth member 10b is formed by setting an insert bar 50 on a rope-shaped fixing member 11 to fix a plurality of zipper teeth 12. As described above, a zipper 2 having an opening and closing insert 20 is formed without using a zipper tape.

[0115] However, in this invention, it is also possible to use, for example... Figure 8 The zipper 3 shown in the figure is a modified example of the present invention, in which a base bar 30a and a base body 40a are provided on a first zipper tooth strip 70a formed by fixing a plurality of zipper teeth 12 on a strip-shaped zipper strip 71, and an insert bar 50a is provided on a second zipper tooth strip 70b formed by fixing a plurality of zipper teeth 12 on a strip-shaped zipper strip 71, thereby forming a zipper 3 having an opening and closing insert 20a.

[0116] Here, while referring to Figure 8 Let's briefly explain the modified zipper 3.

[0117] The modified zipper 3 includes: a pair of first zipper tooth strips 70a and 70b, which are formed by mounting a plurality of synthetic resin zipper teeth 12 on the side edges of the zipper strip 71; a zipper pull (not shown) that is slidably mounted to the tooth rows 7 of the first zipper tooth strips 70a and 70b; and a release insert 20a, which is disposed adjacent to the lower ends of the left and right tooth rows 7. Furthermore, the release insert 20a includes a base bar 30a, a base body 40a, and an insert bar 50a.

[0118] In this variation, the zipper teeth 12 and the zipper pull are formed substantially the same as those in the above embodiment.

[0119] The left and right zipper tapes 71 are formed by weaving or knitting into a tape shape. Each zipper tape 71 has a main body portion and a side edge portion (also called a tooth mounting portion) for mounting the zipper teeth. Core thread portions 72 are provided at the opposite side edges of the left and right zipper tapes 71. The tooth row 7 is formed by injection molding multiple zipper teeth 12 at regular intervals along the tape length onto the side edge portion of the zipper tape 71, including the core thread portions 72.

[0120] The modified base rod 30a has a shape formed by removing the base-side fin portion 39 from the base rod 30 of the above-described embodiment. Furthermore, the modified base rod 30a is substantially the same as the base rod 30 of the embodiment, except that the base-side fin portion 39 is removed. The modified base body 40a is substantially the same as the base body 40 of the above-described embodiment. The modified insert rod 50a has a shape formed by removing the insert rod-side fin portion 59 from the insert rod 50 of the above-described embodiment. Furthermore, the modified insert rod 50a is substantially the same as the insert rod 50 of the embodiment, except that the insert rod-side fin portion 59 is removed.

[0121] Even with the modified zipper 3 with the zipper insert 20a, the zipper insert 20a can function as stably as the zipper 2 on the garment 1 with the zipper insert 20 of the above embodiment. Furthermore, when inserting the seat bar 30a into the seat bar storage portion 42 of the seat body 40a and when using the zipper 3, it is less likely to experience damage such as breakage of the locking claw portion 45. Moreover, the strength of the zipper insert 20a against longitudinal tensile forces can be improved.

[0122] Furthermore, the present invention is not limited to the above-described embodiments. Various modifications can be made as long as the invention has a substantially the same structure and achieves the same effect.

[0123] For example, in the zipper 2 of the above embodiment, the zipper teeth 12 are formed by injection molding thermoplastic resin onto the fixing member 11, and each zipper tooth 12 has an independent shape relative to the adjacent zipper teeth 12 in the front-back direction. However, in the present invention, the shape and material of the zipper teeth are not particularly limited, and the zipper teeth forming a tooth row can also be formed, for example, into a spiral continuous shape obtained by molding monofilaments made of synthetic resin.
