Description

Technical Field

[0001] This invention relates to a product with a slide fastener.

Background Art

[0002] For example, the slide fastener described in Utility Model Registration No. 3243812 (Patent Document 1) has a fastener stringer in which a plurality of fastener elements are attached to a fastener tape, and a slider. Each fastener element has an element base portion and a fin portion that extends from the element base portion toward the inner side of the tape of the fastener tape and has a dimension in the tape thickness direction smaller than that of the element base portion.

[0003] At the shoulder side end of the slider body, the tip of the fin portion of the fastener element is located outside the slider body from the inner wall surface of the flange while the side surface of the element base portion does not contact the flange of the slider. Also, the fastener element is formed such that the ratio of the total fin width to the maximum element width is less than 40%.

[0004] With such a slide fastener, when manufacturing a product with a slide fastener using the slide fastener, it is possible to prevent or suppress the fastener tape of the product with a slide fastener from being exposed between the fastener element and the fastener adherent member.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the slide fastener described in Patent Document 1, fin portions are formed on the fastener elements, which increases the size of the fastener elements in the width direction of the fastener tape.

[0007] For example, when a product with a slide fastener is manufactured, if the fastener tape or fastener elements are exposed between the left and right fastener-attached members, it can easily affect the appearance and aesthetic quality of the product. Therefore, in order to further improve the design or aesthetic quality of products with slide fasteners, there has been a demand to make the fastener elements smaller in the tape width direction, for example, so that the fastener tape and fastener elements are less visible from the outside of the product.

[0008] On the other hand, in order to make the zipper tape and zipper elements less visible, the zipper tape of the zipper stringer may be sewn to the zipper attachment members in a position where the zipper elements without fins are in contact with or close to the zipper attachment members on both sides. However, in this case, if the zipper attachment members are formed thickly depending on the application of the product with a slide fastener, it is conceivable that the slider may interfere with the zipper attachment members when the slider slides, making the slider's sliding operation heavier, and causing problems such as the zipper attachment members getting caught on the slider.

[0009] This invention has been made in view of the above-mentioned problems, and its purpose is to provide a product with a slide fastener that makes the fastener tape and fastener elements less visible between the left and right fastener attachment members, and / or a product with a slide fastener that makes it less likely for problems such as a decrease in the sliding performance of the slider or fabric getting caught in the slider to occur due to the thickness of the fastener attachment member to occur, even if the fastener attachment member is formed to be thick. [Means for solving the problem]

[0010] To achieve the above objective, the present invention provides a product with a slide fastener comprising a slide fastener and a fastener attachment member to which the slide fastener is attached, wherein the slide fastener comprises a pair of left and right fastener stringers and a slider slidably attached to the element row of the fastener stringers, each fastener stringer comprises a fastener tape and a plurality of fastener elements attached to the fastener tape to form the element row, each fastener element comprises a body fixed to the fastener tape and a meshing head integrally formed with the body, the fastener stringer is fixed to the fastener attachment member in a state in which the fastener tape is superimposed on the fastener attachment member in the vertical direction, and the body of the fastener element and the fastener attachment member are in contact or substantially in contact in the left-right direction, and the slider has a shape that does not interfere with the fastener attachment member when viewed in cross-section of the slider and the fastener attachment member perpendicular to the longitudinal direction of the fastener stringer.

[0011] In the slide fastener product of the present invention, the slider has an upper plate portion, a lower plate portion disposed away from the upper plate portion, and a connecting column connecting the upper plate portion and the lower plate portion, and an insertion gap is formed between the left and right side edges of the upper plate portion and the left and right side edges of the lower plate portion through which the fastener tape and the fastener adherend member are inserted, and in the vertical direction, if the distance of the insertion gap is G1, the distance between the side edge of the lower plate portion and the fastener tape is G2, the thickness of the fastener tape is T1, and the thickness of the fastener adherend member is T2, then it is preferable that the relationship G1 ≥ G2 + T1 + T2 is satisfied. Furthermore, it is preferable that the upper plate portion and / or the lower plate portion have a plate-shaped main body portion perpendicular to the vertical direction and left and right flange portions extending vertically from the left and right side edges of the main body portion, and that the body portion of the fastener element has a constant or substantially constant thickness and is formed to enclose the core cord portion of the fastener tape when viewed in cross-section perpendicular to the length direction of the fastener stringer.

[0012] The meshing head is formed to be thinner than the body, a step is formed between the body and the meshing head, and when the left and right fastener elements are meshed, a groove extending in the front-rear direction is formed by the step, and the slider has a retaining portion that protrudes downward from the center of the upper plate in the left-right direction, and it is preferable that the retaining portion moves within the groove when the slider is slid.

[0013] In this invention, the body portion and the interlocking head portion are formed to have the same or substantially the same dimensions in the vertical direction, and it is preferable that the center of the fastener tape is positioned below the center of the interlocking head portion in the vertical direction. Furthermore, the body portion may protrude above the interlocking head, and the center position of the interlocking head and the center position of the fastener tape may be located at the same position in the vertical direction.

[0014] In this invention, the slider has an upper plate portion, a lower plate portion disposed apart from the upper plate portion, and a connecting column connecting the upper plate portion and the lower plate portion. One of the upper plate portion and the lower plate portion is formed only by a plate-shaped main body portion perpendicular to the vertical direction, and the other of the upper plate portion and the lower plate portion has a plate-shaped main body portion perpendicular to the vertical direction and left and right flange portions extending vertically from the left and right side edges of the main body portion. The main body portion of one of the upper plate portion and the lower plate portion may be formed to be positioned further inward in the left-right direction than the flange portion of the other upper plate portion and the lower plate portion. [Effects of the Invention]

[0015] According to the slide fastener product of this invention, since the fastener elements are formed without fins, the size of the fastener elements exposed between the left and right fastener-attached members in the tape width direction can be reduced, making the fastener tape and fastener elements less visible between the left and right fastener-attached members. Furthermore, if the slide fastener product satisfies predetermined conditions, even if the fastener-attached member is formed thickly, it is less likely to cause problems such as a decrease in the sliding performance of the slider or fabric getting caught in the slider due to the thickness of the fastener-attached member. [Brief explanation of the drawing]

[0016] [Figure 1] This is a plan view showing the main parts of the product with a slide fastener according to Example 1. [Figure 2] Figure 1 is a cross-sectional view showing the product with a slide fastener along line II-II. [Figure 3] This is a cross-sectional view showing a cross-section of a product with a slide fastener according to Example 2. [Figure 4] This is a cross-sectional view showing a cross-section of the product with a slide fastener according to Example 3. [Figure 5] This is a cross-sectional view showing a cross-section of the product with a slide fastener according to Example 4. [Modes for carrying out the invention] [Examples]

[0017] Figure 1 is a schematic plan view showing the main parts of product 1 with a slide fastener according to Example 1. Figure 2 is a cross-sectional view showing the product 1 with a slide fastener shown in Figure 1 along line II-II. Note that in Figure 2 and Figures 3 to 5 from Example 2 onward, the neck portion 22 and the meshing head portion 23 of one (right) fastener element 20 are omitted from the illustration in order to clearly show the characteristics of the fastener element 20.

[0018] In the following description of the slide fastener 10 and the product 1 with a slide fastener, the front-back direction refers to the direction along the length direction of the fastener stringer 11 and the fastener tape 12, and is the same direction as the sliding direction in which the slider 30 slides. For example, when closing the slide fastener 10, the direction in which the slider 30 slides is defined as the front, and when opening the slide fastener 10, the direction in which the slider 30 slides is defined as the back.

[0019] The left-right direction refers to the direction along the tape width direction of the fastener tape 12. Specifically, it is a direction orthogonal to the front-back direction and parallel to the tape surface and the tape back surface of the fastener tape 12. Also, the left-right direction can be said to be the direction along which the pair of element rows 13 mesh with and separate from each other. In this case, the direction in which the pair of element rows 13 move closer to each other is defined as the inner direction of the left-right direction, and the direction in which the pair of element rows 13 move away from each other is defined as the outer direction of the left-right direction.

[0020] The up-down direction refers to the direction orthogonal to the tape surface and the tape back surface of the fastener tape 12 or the direction along the tape thickness direction, and is a direction orthogonal to the front-back direction and the left-right direction. For example, the direction in which the handle 40 of the slider 30 is arranged with respect to the fastener tape 12 is defined as the up direction, and the opposite direction is defined as the down direction.

[0021] The product 1 with a slide fastener shown in FIG. 1 is a piece of clothing (apparel), and the slide fastener 10 is attached to the front opening part of the front body of this piece of clothing. This piece of clothing 1 with a slide fastener has a slide fastener 10 having a pair of left and right fastener stringers 11 on which element rows 13 are formed on the fastener tape 12, and a fastener-attaching member 6 having left and right stringer attachment edges 7 to which the left and right fastener stringers 11 are attached. The slide fastener 10 has a pair of left and right fastener stringers 11 on which element rows 13 are formed on the fastener tape 12, and a slider 30 slidably attached to the left and right element rows 13.

[0022] The fastener attachment member 6 to which the slide fastener 10 is attached is the garment fabric 6 (also called garment fabric). The left and right fabrics 6 that form the front of the garment each have a fabric body (not shown) and opposing side edges that are positioned opposite the other fabric 6. The opposing side edges of the left and right fabrics 6 are formed as stringer attachment edges 7 to which the fastener stringer 11 of the slide fastener 10 is attached, and extend inward from the edge of the fabric body in the left-right direction.

[0023] The stringer attachment edge 7 of the fabric 6 may have, for example, a double portion (not shown) formed by overlapping the fabric 6 in the vertical direction. The double portion of the stringer attachment edge 7 is formed in a U-shape in a cross-sectional view perpendicular to the front-to-back direction by folding the fabric 6 back at a bending portion along the front-to-back direction.

[0024] The stringer attachment edge 7 of the fabric 6 and the zipper tape 12 of the zipper stringer 11 are fixed to each other in a state where the stringer attachment edge 7 and the zipper tape 12 are overlapped in the vertical direction, and the stringer attachment edge 7 is in contact with or substantially in contact with the body portion 21 of the zipper element 20 in the horizontal direction. Possible fixing methods include sewing or welding. For example, the stringer attachment edge 7 and the zipper stringer 11 may be sewn together by a sewn portion (not shown) formed by sewing with a sewing machine. The sewn portion is formed by sewing thread including the upper thread (needle thread) and lower thread (bobbin thread) of the sewing machine. Alternatively, the fabric 6 may be fixed without forming a double portion, with a single piece of fabric 6 and the zipper tape 12 overlapping in the vertical direction, and the fabric 6 being in contact with or substantially in contact with the body portion 21 of the zipper element 20 in the horizontal direction.

[0025] Here, "the fabric 6 is in approximate contact with the body 21 of the zipper element 20" means, for example, that in the front-to-back direction, there are both areas where the fabric 6 and the body 21 of the zipper element 20 are in contact and areas where they are slightly separated, or that the fabric 6 and the body 21 of the zipper element 20 are separated by, for example, 2 mm or less, but appear to be in contact at first glance. Furthermore, in relation to the slider 30, the approximate contact of the fabric 6 with the body 21 of the zipper element 20 prevents the upper flange portion 32b and the lower flange portion 33b from getting caught between the fabric 6 and the body 21.

[0026] For example, as shown in Figure 2, each left and right fastener stringer 11 has a long, narrow fastener tape 12 and a plurality of synthetic resin fastener elements 20 formed on the side edges of the fastener tape 12. The fastener tape 12 has a tape body portion having a tape surface and a tape back surface, and a core cord portion 12a provided on the inner side edge of the tape body portion. The core cord portion 12a is integrally provided on the side edge of the tape body portion along the length direction of the tape. The core cord portion 12a is formed to bulge in the vertical direction relative to the tape body portion.

[0027] Multiple fastener elements 20 are provided at regular intervals along the front-to-back direction on the side edge of the fastener tape 12, including the core cord portion 12a, thereby forming an element row 13. Each fastener element 20 is formed independently of adjacent fastener elements 20 by injection molding synthetic resin into the fastener tape 12.

[0028] Each fastener element 20 has a body portion 21 fixed to the fastener tape 12, a neck portion 22 extending inward from the body portion 21 in the left-right direction, a meshing head portion 23 further extending inward from the neck portion 22 in the left-right direction, a pair of shoulder portions 24 extending in the front-rear direction from the neck portion 22, and a groove portion 25 formed at the tip of the meshing head portion 23. In the fastener element 20 shown in Figure 2, the body portion 21, the neck portion 22, and the meshing head portion 23 are formed with the same or approximately the same thickness. Here, the thickness of the body portion 21, the neck portion 22, and the meshing head portion 23 is the vertical dimension from the top surface to the bottom surface of each part.

[0029] The body portion 21 has a roughly rectangular parallelepiped shape, and when viewed in cross-section perpendicular to the front-to-back direction of the fastener stringer 11 (see Figure 2), it is formed to enclose the core cord portion 12a of the fastener tape 12. The body portion 21 is formed such that its thickness is constant or approximately constant. For example, the upper and lower surfaces of the body portion 21 are formed by flat surfaces perpendicular to the vertical direction and are also arranged parallel to each other. This allows the body portion 21 to have a constant thickness. The body portion 21 is said to have an approximately constant thickness when the upper and / or lower surfaces of the body portion 21 are formed with a slight inclination or curvature relative to the plane perpendicular to the vertical direction, for example, when the thickness of the body portion 21 changes within a range of ±10%.

[0030] As shown in Figure 2, the fastener tape 12 is positioned offset to the lower side in the vertical direction relative to the body 21, neck 22, and interlocking head 23 of the fastener element 20, and in the vertical direction, the tape center of the fastener tape 12 is located below the center positions of the body 21, neck 22, and interlocking head 23. For this reason, the body 21 is formed such that, for example, the thickness from the tape center (or core cord portion 12a) of the fastener tape 12 to the upper surface of the body 21 is thicker than the thickness from the tape center (or core cord portion 12a) to the lower surface of the body 21. For example, it is preferable that the thickness from the tape center of the fastener tape 12 to the upper surface of the body 21 is 120% or more of the thickness from the tape center to the lower surface of the body 21.

[0031] Because the fastener element 20 having the body portion 21 described above is formed on the fastener tape 12, even if the stringer attachment edge 7 of the fabric 6 is formed to a certain extent, as shown in Figure 2, the upper surface of the fabric 6 can be positioned lower than the upper surface of the body portion 21 of the fastener element 20. This allows the stringer attachment edge 7 of the fabric 6 and the fastener tape 12 to be inserted between the upper plate portion 32 and the lower plate portion 33 of the slider 30.

[0032] In this case, the stringer attachment edge 7 of the fabric 6 may have a thickness of, for example, 2 to 20 times the thickness of the fastener tape 12. Furthermore, it is preferable that the stringer attachment edge 7 of the fabric 6 is formed with a thickness of, for example, 25% to 50% of the thickness of the body portion 21 of the fastener element 20.

[0033] The neck portion 22 of the fastener element 20 is positioned between the body portion 21 and the interlocking head portion 23 in the left-right direction, and has a shape that is constricted in the front-rear direction so that it can engage with the interlocking head portions 23 of two fastener elements 20 that it interlocks with. The shoulder portion 24 of the fastener element 20 extends forward and backward from the neck portion 22 and is formed to be insertable into the recessed groove portion 25 formed in the fastener element 20 that it engages with.

[0034] The interlocking head 23 of the fastener element 20 extends continuously from the neck portion 22 and is therefore integrally formed with the body portion 21 via the neck portion 22. When the fastener element 20 is viewed from above or below, the interlocking head 23 has a roughly elongated oval shape that is long in the front-to-back direction. The upper and lower surfaces of the body portion 21, the neck portion 22, and the interlocking head 23 each form a single plane perpendicular to the vertical direction.

[0035] The meshing head 23 is formed so that it can mesh with the mating fastener element 20 over its entire length in the vertical direction. However, the meshing head 23 may be formed so that it can mesh with the mating fastener element 20 over at least a portion of its length in the vertical direction. For example, the meshing head 23 may have a shape such that its lower half meshes with the meshing head 23 of the mating fastener element 20, while its upper half does not mesh with the mating fastener element 20 and is inserted between the meshing heads 23 of the two fastener elements 20.

[0036] The slider 30 comprises a slider body 31 and a pull handle 40 attached to the slider body 31. The shape, size, material, etc., of the pull handle 40 are not limited. The material of the slider body 31 is also not limited; the slider body 31 may be made of metal, for example, or of synthetic resin. The slider body 31 has an upper plate portion 32, a lower plate portion 33 positioned below the upper plate portion 32, a connecting column (not shown) connecting the upper plate portion 32 and the lower plate portion 33, and a handle attachment portion 34 formed on the upper plate portion 32 to which a handle 40 is attached.

[0037] The front end of the slider body 31 has left and right shoulders formed on either side of a connecting column. The rear end of the slider body 31 has a rear opening. Between the upper plate portion 32 and the lower plate portion 33 of the slider body 31, there is a roughly Y-shaped element guide path that communicates with the left and right shoulders and the rear opening, and an insertion gap through which the fastener tape 12 and the stringer attachment edge 7 of the fabric 6 are inserted. The insertion gap is formed between the lower surfaces of the left and right side edges of the upper plate portion 32 and the upper surfaces of the left and right side edges of the lower plate portion 33. The insertion gap is located on the left and right outer sides of the element guide path and is in communication with the element guide path.

[0038] In the slider body 31 shown in Figure 2, the upper plate portion 32 has a flat upper plate body portion 32a and upper flange portions 32b that protrude downward from the left and right side edges of the upper plate body portion 32a. A step is formed between the element guide surface, which is the lower surface of the upper plate body portion 32a, and the lower surface of the upper flange portion 32b. The lower plate portion 33 has a flat lower plate body portion 33a and lower flange portions 33b that protrude upward from the left and right side edges of the lower plate body portion 33a. A step is formed between the element guide surface, which is the upper surface of the lower plate body portion 33a, and the upper surface of the lower flange portion 33b. Inside the slider body 31, the body 21 of the fastener element 20 contacts the upper flange portion 32b of the upper plate portion 32 and the lower flange portion 33b of the lower plate portion 33 from the left and right directions, thereby restricting the position of the fastener element 20 in the left and right directions.

[0039] Upper flange portions 32b, which are part of the upper plate portion 32, are provided on the left and right side edges of the upper plate portion 32, and lower flange portions 33b, which are part of the lower plate portion 33, are provided on the left and right side edges of the lower plate portion 33. Therefore, in the slider body 31 shown in Figure 2, the insertion gap through which the fastener tape 12 and the fabric 6 are inserted is formed between the lower surface of the upper flange portion 32b of the upper plate portion 32 and the upper surface of the lower flange portion 33b of the lower plate portion 33.

[0040] In the garment 1 with a slide fastener shown in Figure 1, the vertical distance between the left and right side edges of the upper plate portion 32 and the left and right side edges of the lower plate portion 33 is the insertion gap, and the size of this insertion gap is defined as "G1". As an example, in the slider body 31 shown in Figure 2, the size G1 of the insertion gap is the vertical dimension from the lower surface of the upper flange portion 32b, which is the side edge of the upper plate portion 32, to the upper surface of the lower flange portion 33b, which is the side edge of the lower plate portion 33.

[0041] The magnitude of the vertical gap between the side edge of the lower plate portion 33 (the upper surface of the lower flange portion 33b) and the fastener tape 12 is defined as "G2". As an example, in the slider body 31 shown in Figure 2, the magnitude of the gap G2 is the vertical dimension from the back surface (bottom surface) of the fastener tape 12 at the position where the stringer attachment edge 7 of the fabric 6 overlaps, to the upper surface of the lower flange portion 33b of the slider body 31. The thickness of the fastener tape 12 at the position where the stringer attachment edge 7 of the fabric 6 overlaps, and the thickness of the stringer attachment edge 7 of the fabric 6 (fastener attachment member 6), are defined as "T1" and "T2," respectively.

[0042] In this case, the garment 1 with a slide fastener shown in Figure 1 is formed to satisfy the relationship "G1≧G2+T1+T2" in the formula. As a result, the slider 30 can have a shape that does not interfere with the stringer mounting edge 7 when viewed in a cross-section perpendicular to the front-to-back direction of the slider 30 and the fabric 6. The shape that prevents the slider 30 from interfering with the stringer mounting edge 7 can also be rephrased as a shape that allows the slider 30 to slide on the stringer mounting edge 7 without deforming the stringer mounting edge 7 by the slider 30 pressing on the stringer mounting edge 7 of the fabric 6, or a shape in which the stringer mounting edge 7 is not positioned on the trajectory of the upper plate portion 32 and lower plate portion 33 when the slider 30 slides, even without deforming the stringer mounting edge 7.

[0043] According to the garment with a slide fastener 1 of Embodiment 1, as shown in Figures 1 and 2, the fastener element 20 is formed without a fin portion as in Patent Document 1, so the fastener element 20 can be made smaller in the left-right direction than in Patent Document 1. Therefore, the fastener element 20 can be made less visible between the left and right fabrics 6 compared to, for example, the fastener element in Patent Document 1.

[0044] In addition, in garment 1 with a slide fastener, the fastener stringer 11 is fixed to the fabric 6 in a state where the fabric 6 is in direct or near-direct contact with the body portion 21 of the fastener element 20 in the left-right direction. This prevents or suppresses the exposure of the fastener tape 12 between the fastener element 20 and the fabric 6. This prevents or suppresses damage to the design and appearance quality of clothing due to the exposure of the zipper element 20 and zipper tape 12, making it easier to manufacture clothing with excellent design or high appearance quality.

[0045] Furthermore, even if the fabric 6 that comes into contact with or nearly contacts the zipper element 20 is made thicker, for example depending on the intended use of the garment, the garment 1 with the slide fastener is formed such that it satisfies the relationship of the formula "G1≧G2+T1+T2" by making the body portion 21 of the zipper element 20 thicker, and by reducing the step between the upper plate body portion 32a and the upper flange portion 32b of the slider body 31, and the step between the lower plate body portion 33a and the lower flange portion 33b.

[0046] As a result, even if the zipper element 20 does not have a fin portion, when sliding the slider 30 of the slide fastener 10, the upper plate portion 32 of the slider 30 is less likely to interfere with the thick fabric 6, thereby preventing or suppressing problems such as the slider 30 getting caught on the fabric 6 or the fabric 6 getting jammed in the slider 30. As a result, a decrease in the sliding performance of the slider 30 due to the thickness of the fabric 6 is prevented, and good sliding operation of the slider 30 can be stably obtained.

[0047] The garment 1 with a slide fastener in Example 1 may also be formed, for example, by shaping the left and right fastener stringers 11 so that their vertical orientation is reversed compared to the fastener stringers 11 shown in Figure 2, and by fixing the stringer attachment edges 7 of the fabric 6 to the fastener tape 12 on the back (bottom) side of the fastener tape 12. [Examples]

[0048] Figure 3 is a schematic cross-sectional view showing a cross-section of garment 2 with a slide fastener according to Example 2. In the garment with a slide fastener 2 of Embodiment 2 shown in Figure 3, for example, compared to the garment with a slide fastener 1 of Embodiment 1 shown in Figure 2, the fabric 6 that contacts or substantially contacts the fastener element 20 is formed to be thicker, and the upper plate portion 52 of the slider body 51 is formed only by a plate-shaped upper plate body portion 52a, without the left and right upper flange portions 32b.

[0049] Furthermore, the garment with a slide fastener 2 shown in Figure 3 is substantially the same as the garment with a slide fastener 1 shown in Figure 2, except that the thickness of the fabric 6 and the shape of the upper plate portion 52 of the slider body 51 are different. For example, the fastener tape 12 and fastener element 20 shown in Figure 3 are the same as the fastener tape 12 and fastener element 20 shown in Figure 2. For this reason, in the description of Example 2, and the following Examples 3 and 4, parts and components that are substantially the same as those of the garment with a slide fastener 1 described in Example 1 will be represented using the same reference numerals as in Example 1, and their detailed explanation will be omitted.

[0050] In the garment 2 with a slide fastener shown in Figure 3, the stringer attachment edge 7 of the fabric 6 has a double layer where the fabric 6 is overlapped vertically. The fastener tape 12 of the fastener stringer 11 is fixed to this double layer of fabric 6 by sewing, for example, with a sewing machine. The stringer attachment edge 7 of the fabric 6 is in contact with or nearly in contact with the body portion 21 of the fastener element 20 in the left-right direction, and is fixed to the fastener tape 12 by a sewing part (not shown), etc.

[0051] In Figure 3, the stringer attachment edge 7 of the fabric 6 is formed with a thickness of, for example, 50% or more but less than 100% of the thickness of the body portion 21 of the fastener element 20, preferably greater than 50% but 80% or less of the thickness of the body portion 21.

[0052] The slider body 51 of the slider 50 shown in Figure 3 has an upper plate portion 52, a lower plate portion 33 positioned below the upper plate portion 52, a connecting column (not shown) connecting the upper plate portion 52 and the lower plate portion 33, and a handle attachment portion (not shown) formed on the upper plate portion 52 to which a handle is attached. The upper plate portion 52 is formed only by a plate-shaped upper plate body portion 52a, without an upper flange portion 32b as shown in Figure 2.

[0053] The lower plate portion 33 shown in Figure 3, like the lower plate portion 33 shown in Figure 2, has a plate-shaped lower plate body portion 33a and lower flange portions 33b that protrude downward from the left and right side edges of the lower plate body portion 33a. In this slider body 51, the body portion 21 of the fastener element 20 contacts the lower flange portion 33b of the lower plate portion 33 from the left and right directions inside the slider body 51, thereby restricting the position of the fastener element 20 in the left and right directions.

[0054] In the slider body 51 shown in Figure 3, the insertion gap through which the fastener tape 12 and fabric 6 are inserted is formed between the lower surfaces of the left and right side edges of the upper plate body 52a and the upper surface of the lower flange portion 33b of the lower plate portion 33. Therefore, the size G1 of the insertion gap in the slider body 51 is the vertical dimension from the lower surface of the upper plate body 52a to the upper surface of the lower flange portion 33b.

[0055] In the slider body 51 shown in Figure 3, the magnitude G2 of the vertical distance between the side edge of the lower plate portion 33 and the fastener tape 12 is the same as in the slider body 31 shown in Figure 2, and is the vertical dimension from the back surface (bottom surface) of the fastener tape 12 to the upper surface of the lower flange portion 33b of the slider body 51. Furthermore, "T1" and "T2" are defined in the same way as in Embodiment 1 of Figure 2.

[0056] In this case, the product 2 with the slide fastener shown in Figure 3 is formed to satisfy the relationship "G1≧G2+T1+T2". As a result, the slider 50 can have a shape that does not interfere with the fabric 6 when viewed in a cross section perpendicular to the front-to-back direction of the slider 50 and the fabric 6.

[0057] Furthermore, in the slider body 51 shown in Figure 3, the lower surface (element guide surface) of the upper plate portion 52 and the upper surface (element guide surface) of the lower plate portion 33 are arranged to contact or be in close proximity to the upper and lower surfaces of the body portion 21, neck portion 22, and interlocking head portion 23 of the fastener element 20 inside the slider body 51, respectively. This prevents or suppresses the fastener element 20 from tilting diagonally from, for example, the orientation shown in Figure 3, and as a result, it is difficult for the fastener element 20 to slip out in the left and right directions through the insertion gaps formed in the slider body 51.

[0058] In the garment with a slide fastener 2 of Embodiment 2 shown in Figure 3, the fastener stringer 11 is fixed to the fabric 6 while the fabric 6 is in contact with or nearly in contact with the fastener element 20 in the left-right direction. Therefore, it is possible to prevent or suppress the exposure of the fastener tape 12 between the fastener element 20 and the fabric 6.

[0059] Furthermore, even if, for example, the fabric 6 in Embodiment 2 shown in Figure 3 is formed to be thicker than the fabric 6 in Embodiment 1 shown in Figure 2, the garment 2 with the slide fastener is formed to satisfy the relationship of the formula "G1≧G2+T1+T2" by making the body portion 21 of the fastener element 20 thicker, forming the upper plate portion 52 of the slider body 51 without providing the upper flange portion 32b, and reducing the step between the lower plate body portion 33a and the lower flange portion 33b of the slider body 51. This prevents or suppresses problems such as the slider 50 getting caught on the thick fabric 6 or the thick fabric 6 getting jammed in the slider 50 when the slider 50 is slid.

[0060] In the garment 2 with a slide fastener of Embodiment 2, for example, the stringer attachment edge 7 of the fabric 6 is fixed to the fastener tape 12 on the back (bottom) side of the fastener tape 12, and the upper plate portion 52 of the slider body 51 has an upper plate body portion 52a and an upper flange portion (not shown), while the lower plate portion 33 may be formed only by the lower plate body portion 33a without a lower flange portion 33b. [Examples]

[0061] Figure 4 is a schematic cross-sectional view showing a cross-section of garment 3 with a slide fastener according to Example 3. In the garment with a slide fastener 3 of Embodiment 3 shown in Figure 4, for example, compared to the garment with a slide fastener 2 of Embodiment 2 shown in Figure 3, the fabric 6 that contacts or substantially contacts the fastener element 20 is formed to be even thicker, and the upper plate portion 62 of the slider body 61 is formed to be smaller in the left-right direction than the lower plate portion 33.

[0062] Furthermore, the garment with a slide fastener 3 in Figure 4 is substantially the same as the garment with a slide fastener 1 in Embodiment 1 shown in Figure 2, except that the thickness of the fabric 6 and the shape of the upper plate portion 62 of the slider body 61 are different.

[0063] In the garment 3 with a slide fastener shown in Figure 4, the stringer attachment edge 7 of the fabric 6 has a double layer, and the fastener tape 12 of the fastener stringer 11 is fixed to this double layer of fabric 6. Furthermore, the stringer attachment edge 7 of the fabric 6 is fixed to the fastener tape 12 in a state where it is in contact with or nearly in contact with the body portion 21 of the fastener element 20 in the left-right direction.

[0064] As shown in Figure 4, the stringer attachment edge 7 of the fabric 6 can have a thickness greater than the vertical dimension of the upper half of the body 21, for example, from the position of the lower surface of the upper plate portion 62 of the slider body 61 to the position of the surface (upper surface) of the fastener tape 12. Considering the sliding operation of the slider 60, it is preferable that the stringer attachment edge 7 of the fabric 6 be formed thinner than the overall thickness of the slider body 61, for example. Note that in Figure 4, the stringer attachment edge 7 of the fabric 6 may be formed thinner than the vertical dimension of the upper half of the body 21.

[0065] The slider body 61 of the slider 60 shown in Figure 4 has an upper plate portion 62, a lower plate portion 33 positioned below the upper plate portion 62, a connecting column (not shown) connecting the upper plate portion 62 and the lower plate portion 33, and a handle attachment portion (not shown) formed on the upper plate portion 62 to which a handle is attached.

[0066] The upper plate portion 62 shown in Figure 4 does not have an upper flange portion 32b as shown in Figure 2, and is formed only by a plate-shaped upper plate body portion 62a. The upper plate portion 62 is formed to be small in size so that, for example in a plan view of the slider 60, it does not overlap with the left and right lower flange portions 33b of the lower plate portion 33 in the vertical direction, and in the left and right direction, it is positioned inward from the positions of the left and right lower flange portions 33b. For this reason, the left and right lower flange portions 33b of the lower plate portion 33 are formed so that, for example in a plan view of the slider body 61 viewed from above, they are exposed outward in the left and right direction compared to the upper plate portion 62.

[0067] In the slider body 61 shown in Figure 4, the insertion gap through which the fastener tape 12 and the fabric 6 are inserted is formed by the space above the upper surface of the lower flange portion 33b of the lower plate portion 33. Therefore, the upper limit of the vertical dimension of the insertion gap is not limited by the upper plate portion 62 of the slider body 61.

[0068] In the slider body 61 shown in Figure 4, the lower surface (element guide surface) of the upper plate portion 62 and the upper surface (element guide surface) of the lower plate portion 33 are arranged to contact or be in close proximity to the upper and lower surfaces of the body portion 21, neck portion 22, and interlocking head portion 23 of the fastener element 20 inside the slider body 61, respectively. Furthermore, each fastener element 20 is held inside the slider body 61 with its body portion 21 in contact with or nearly in contact with the thick fabric 6 in the left-right direction. For this reason, in the garment 3 with a slide fastener shown in Figure 4, the orientation of the fastener element 20 inside the slider body 61 can be made less likely to tilt diagonally from, for example, the orientation shown in Figure 4.

[0069] In the garment with a slide fastener 3 of Embodiment 3 shown in Figure 4, the fastener stringer 11 is fixed to the fabric 6 while the thick fabric 6 is in contact with or nearly in contact with the fastener element 20 from the left and right directions. Therefore, it is possible to prevent or suppress the exposure of the fastener tape 12 between the fastener element 20 and the fabric 6.

[0070] Furthermore, in the slider body 61, the left and right insertion gaps for inserting the fastener tape 12 and the fabric 6 are not restricted by the upper plate portion 62, and are formed to be large in the vertical direction. As a result, the slider 60 can have a shape that does not interfere with the fabric 6, even if the fabric 6 is formed to be thick, when viewed in a cross-section perpendicular to the front-to-back direction of the slider 60 and the fabric 6. Therefore, when sliding the slider 60 of the slide fastener, problems such as the slider 60 getting caught on the thick fabric 6 or the thick fabric 6 getting jammed in the slider 60 can be prevented or suppressed.

[0071] In the garment 3 with a slide fastener of Embodiment 3, for example, the stringer attachment edge 7 of the fabric 6 is fixed to the fastener tape 12 on the back (bottom) side of the fastener tape 12, and the upper plate portion 62 of the slider body 61 has an upper plate body portion 62a and an upper flange portion (not shown), and the lower plate portion 33 is formed to be positioned inward in the left-right direction from the position of the upper flange portion. [Examples]

[0072] Figure 5 is a schematic cross-sectional view showing a cross-section of garment 4 with a slide fastener according to Example 4. In the garment with a slide fastener 4 of Embodiment 4 shown in Figure 5, for example, compared to the garment with a slide fastener 1 of Embodiment 1 shown in Figure 2, the neck portion 22a and the interlocking head portion 23a of the fastener element 20a are formed to be thinner than the body portion 21, and the slider body 71 of the slider 70 is formed with an additional retaining portion 73.

[0073] Furthermore, the garment with a slide fastener 4 in Figure 5 is substantially the same as the garment with a slide fastener 1 in Embodiment 1 shown in Figure 2, except that the neck portion 22a and the interlocking head portion 23a are thinner than the body portion 21, and a retaining portion 73 is added to the slider body 71.

[0074] The fastener element 20a shown in Figure 5 has a body portion 21, a neck portion 22a extending from the body portion 21, a meshing head portion 23a further extending from the neck portion 22a, a pair of shoulder portions 24 extending in the front-rear direction from the neck portion 22a, and a groove portion 25 formed at the tip of the meshing head portion 23a. The body portion 21, shoulder portions 24, and groove portion 25 of the fastener element 20a shown in Figure 5 are formed substantially the same as those of the fastener element 20 of Embodiment 1 shown in Figure 2.

[0075] When the fastener element 20a is viewed from above or below, the neck portion 22a of the fastener element 20a has a shape that is constricted in the front-to-back direction, and the meshing head portion 23a has a roughly elongated oval shape that is long in the front-to-back direction. The neck portion 22a and the meshing head portion 23a are formed to be thinner than the body portion 21. For example, the neck portion 22a and the meshing head portion 23a have a thickness of 50% or more but less than 100% of the thickness of the body portion 21, preferably 60% or more but 90% or less.

[0076] The interlocking head 23a is formed such that, in the vertical direction, the center position of the interlocking head 23a and the center of the fastener tape 12 are at the same height. As a result, in the garment with a slide fastener 4 shown in Figure 5, even if the left and right fastener tapes 12 are pulled outward in the left-right direction while the left and right fastener elements 20a are interlocked, the interlocking state of the fastener elements 20a can be maintained more stably compared to the garment with a slide fastener 1 of Embodiment 1 shown in Figure 2, for example, thus improving the lateral pull strength of the slide fastener.

[0077] The slider body 71 of the slider 70 has an upper plate portion 32, a lower plate portion 33, a connecting column (not shown) connecting the upper plate portion 32 and the lower plate portion 33, a handle attachment portion (not shown) formed on the upper plate portion 32 to which a handle (not shown) is attached, and a retaining portion 73 that protrudes downward from the lower surface of the upper plate portion 32. The upper plate portion 32, lower plate portion 33, connecting column, and handle attachment portion of the slider body 71 shown in Figure 5 are formed substantially the same as those of the slider body 31 shown in Figures 1 and 2.

[0078] The retaining portion 73 of the slider body 71 is located on the rear side of the connecting column in the slider body 71 and in the center in the left-right direction. The retaining portion 73 contacts or is close to the upper surfaces of the neck portion 22a and the interlocking head portion 23a of the left and right fastener elements 20a inside the slider body 71, thereby pressing the neck portion 22a and the interlocking head portion 23a from above. This makes it difficult for the fastener elements 20a to tilt diagonally from, for example, the orientation shown in Figure 5 within the slider body 71.

[0079] Because the neck portion 22a and the meshing head portion 23a are formed to be thinner than the body portion 21, a step is formed between the body portion 21 and the neck portion 22a and the meshing head portion 23a. When the left and right fastener elements 20a are engaged, the step formed on the left and right fastener elements 20a creates a groove that extends in the longitudinal direction, and the pressing portion 73 of the slider body 71 slides within this groove.

[0080] The retaining portion 73 may be formed by connecting it to the connecting column of the slider body 71 from the rear side, or it may be formed separately from the connecting column of the slider body 71 towards the rear. Furthermore, the slider body 71 may be formed without the retaining portion 73 shown in Figure 5.

[0081] In the garment 4 with a slide fastener shown in the embodiment 4 in Figure 5, the fastener element 20a is formed without a fin portion as in Patent Document 1, making it possible to make the fastener element 20a less visible between the left and right fabrics 6. Furthermore, in garment 4 with a slide fastener, similar to garment 1 with a slide fastener in Example 1, the zipper stringer 11 is fixed to the fabric 6 with the thick fabric 6 in contact with or nearly in contact with the zipper element 20a in the left-right direction. This prevents or suppresses the exposure of the zipper tape 12 between the zipper element 20a and the fabric 6.

[0082] Furthermore, the garment 4 with a slide fastener shown in Figure 5 is formed to satisfy the relationship "G1≧G2+T1+T2" in the same way as the garment 1 with a slide fastener in Embodiment 1 shown in Figure 1. Therefore, when sliding the slider 70 of the slide fastener, problems such as the slider 70 getting caught on the thick fabric 6 or the thick fabric 6 getting jammed in the slider 70 can be prevented or suppressed.

[0083] In addition, in the garment with a slide fastener 4 of Embodiment 4 shown in Figure 5, instead of the slider body 71, a slider body in which the upper flange portion 32b is removed from the slider body 71 may be used, for example as shown in Figure 3, or a slider body in which the upper flange portion 32b is removed from the slider body 71 and the upper plate body portion 32a is positioned further inward in the left-right direction than the position of the lower flange portion 33b may be used, for example as shown in Figure 4.

[0084] This invention is not limited to the above-described Examples 1 to 4, and various modifications are possible as long as they have substantially the same configuration as this invention and produce similar effects. For example, in garments 1 to 4 with slide fasteners in Examples 1 to 4, the fastener elements 20 and 20a are formed in an independent shape by injection molding of synthetic resin. However, in this invention, instead of synthetic resin fastener elements 20 and 20a, a fastener stringer and slide fastener may be formed by attaching a plurality of metal fastener elements, each formed in an independent shape, to the fastener tape.

[0085] Furthermore, while Examples 1 to 4 describe clothing with a slide fastener as a representative example of a product with a slide fastener, the product with a slide fastener in this invention is not limited to clothing. The product with a slide fastener in this invention includes a variety of products such as clothing other than garments, daily necessities such as shoes and bags, industrial materials, and various seat products used in automobiles, trains, aircraft, etc. [Explanation of Symbols]
