Description

Technical Field

[0001] The utility model relates to a detachable stopper for a concealed zipper and a concealed zipper comprising the detachable stopper. Background Art

[0002] One of the advantages of invisible zippers is that the teeth are selectively located on the back side, making them difficult to see from the front. To further improve the flatness of the front side of such invisible zippers, a flat stopper is required on the front side of the invisible zipper (see Utility Model Registration No. 3188025).

[0003] In addition, as a stopper for a hidden zipper, a stopper (also called an opening and closing member) having a structure shown in the following documents is also known. Figure 3 In the figure, the left and right figures show the concave and convex parts, and more specifically, the pin portion of the convex part is shown immediately before being inserted into the groove of the cylindrical part of the concave part. When the pin portion is completely inserted into the groove of the cylindrical part, the convex part is partially covered from the front side by the front plate of the cylindrical part (see reference numeral 721 in the figure).

[0004] Chinese Utility Model No. 2750700 also discloses a stopper of the same type as that of Patent Document 1. Chinese Utility Model No. 2609395 discloses that a female component is assembled from two parts. Utility Model Content

[0005] [Problems to be solved by the utility model]

[0006] Like the stops for ordinary zippers, the stops for invisible zippers need to have the ability to maintain the invisible zipper in a closed state, in short, they need to have sufficient resistance to horizontal pulling. The convex part of the stopper is fixed across both the main part and the folded part of the zipper cloth. In short, it has a base fixed to the main part and a pin fixed to the folded part. According to the research of the creators of the present invention, there is a concern that when the invisible zipper is pulled horizontally, the pin part is given a torque, and the pin part is offset to the back side (that is, on another plane on the back side) compared to the base part. The base part is in the same plane as the part of the zipper cloth that is given tension, and the convex part is relatively deformed, sometimes locally damaged. In addition, in the cases of Patent Documents 1 and 2, similarly, when the invisible zipper is pulled horizontally, the part corresponding to the above-mentioned base part will also be displaced, and it is believed that the same problem will arise.

[0007] As is clear from the above non-limiting description, the inventors of the present invention have discovered a new problem, namely, to suppress the deformation of the convex member of the stopper when the invisible slide fastener is pulled horizontally.

[0008] [Technical means to solve the problem]

[0009] A detachable stopper according to one embodiment of the present invention is a detachable stopper for a concealed zipper, wherein a boundary line or a boundary slit extending in the front-to-back direction is formed between first and second folded portions of first and second zipper fabrics, and first and second fabric main portions of the first and second zipper fabrics are arranged on both sides of the boundary line or the boundary slit. The detachable stopper comprises:

[0010] a convex member that is adjacent to the first fastener element attached to the first folded portion of the first fastener cloth and is fixed to the first fastener cloth at a rear position thereof; and

[0011] a female component that can be separably coupled to the male component and is fixed to the second fastener fabric at a rear position adjacent to the second fastener element attached to the second inverted portion of the second fastener fabric;

[0012] The convex member includes: a first base portion fixed to at least the front and back sides of the first chain cloth main portion; and a first pin portion fixed to the first folded portion and extending in the front-back direction at a position further back than the first base portion;

[0013] The concave member includes: a receiving portion having a receiving groove formed in the front-to-back direction for inserting and removing the first pin portion; and a front side cover for at least partially covering the convex member from the front side when the first pin portion is inserted into the receiving groove;

[0014] The convex member has a convex portion protruding in the front-back direction, and the front side cover has a stopper surface that prevents the convex portion from being displaced in a direction away from the second fastener cloth when at least the first pin portion is completely inserted into the receiving groove.

[0015] and a second zipper strip having a first end and a second end, wherein the first zipper strip is attached to the first folded portion of the first zipper strip; and a second zipper strip having a second end and a second end, wherein the second zipper strip is attached to the second folded portion of the second zipper strip.

[0016] The convex member includes: a first base portion fixed to at least the front and back sides of the first chain cloth main portion; and a first pin portion fixed to the first folded portion and extending in the front-back direction at a position further back than the first base portion;

[0017] The concave member includes: a receiving portion having a receiving groove formed in the front-to-back direction for inserting and removing the first pin portion; and a front side cover for at least partially covering the convex member from the front side when the first pin portion is inserted into the receiving groove;

[0018] The convex member has a convex portion protruding in the front-back direction, and the front side cover has a stopper surface that prevents the convex portion from being displaced in a direction away from the second fastener cloth when at least the first pin portion is completely inserted into the receiving groove.

[0019] Regarding the above-mentioned detachable stopper or invisible zipper, the features described in the appendix can be applied individually or in any combination.

[0020] [Effects of the utility model]

[0036] The following describes various embodiments and features with reference to the accompanying drawings. Those skilled in the art will be able to combine the various embodiments and / or features without further explanation and understand the synergistic effects resulting from such combinations. In principle, repetitive descriptions between embodiments will be omitted. The accompanying drawings are primarily for the purpose of illustrating the utility model and are simplified for ease of illustration.

[0037] Each feature is understood to be a universal feature, and is not only effective for the detachable stopper for the invisible slide fastener of the present invention, but can also be generally applied to various other detachable stoppers for invisible slide fasteners not disclosed in this specification.

[0038] In this specification, the front-to-back direction corresponds to the length direction of the invisible zipper (or its zipper fabric and zipper fabric), the left-to-right direction corresponds to the width direction of the invisible zipper (or its zipper fabric and zipper fabric), and the front-to-back direction corresponds to a direction orthogonal to both the front-to-back and left-to-right directions. Furthermore, the above directions can be redefined so that the front-to-back direction corresponds to the direction of movement of the slider used to open and close the invisible zipper.

[0039] First, the structure of the invisible zipper 1 will be described. Figure 1As shown, the invisible zipper 1 is a long strip extending in a specific direction with a specific width. It can be installed in the opening of an article (not shown), such as clothing, bags, or shoes, to open and close the opening. The surface 1m of the invisible zipper 1 is not provided with the sprockets 4 and 6 described below, and is therefore highly flat. Therefore, when installed on an article, the invisible zipper 1 is inconspicuous.

[0040] The concealed zipper 1 includes a (first or left) zipper tape 2m, a (second or right) zipper tape 2n, a slider 8, and a detachable stopper 10. The zipper tape 2m includes a (first or left) zipper fabric 3 and a (first or left) fastener element 4. Similarly, the zipper tape 2n includes a (second or right) zipper fabric 5 and a (second or right) fastener element 6. In this specification, terms such as "first" and "second" or directional terms may be used to distinguish between elements with the same name, but these terms may be omitted for simplicity.

[0041] Typically, the zipper fabrics 3 and 5 are woven, knitted, or a mixture thereof, and extend in the same specific direction as the invisible zipper 1. In the illustrated example, the sprockets 4 and 6 are coil-shaped (a spiral of monofilaments with interlocking heads spaced at specific intervals), but are not limited to this and may also be rows of resin or metal sprockets. Resin sprockets can be attached to the zipper fabric by injection molding. Metal sprockets can be attached to the zipper fabric by crimping.

[0042] The fastener fabric 3 has two side ends 38 and 39 located at both ends in the width direction and extending in the length direction (see Figure 2 The fastener fabric 3 is bent along an imaginary line parallel to its longitudinal direction between its two side ends 38 and 39 to have a folded portion 31 and a fabric main portion 35 (see Figure 2 、 3 The width of the folded portion 31 is set to a sufficient degree for mounting the fastener elements, and is therefore sufficiently smaller than the width of the main fabric portion 35, typically 1 / 3 or less.

[0043] The boundary between the folded portion 31 and the main chain fabric portion 35 can be determined by whether or not the boundary is located on the plane PL where the main chain fabric portion 35 is located (see FIG. Figure 3 ) to distinguish. For example, Figure 3 In the fastener fabric 3, when it extends beyond the boundary B1, it extends away from the plane PL. Therefore, the boundary B1 can be used to distinguish the folded portion 31 from the fabric main portion 35. Furthermore, the folded portion 31 includes the folded ends formed by the folding, and these folded ends face the center plane CP of the concealed zipper 1, which includes the center line CL. Regarding the fastener fabric 5, the same description as above applies, except that the side ends 38 and 39 are replaced with side ends 58 and 59, the folded portion 31 is replaced with the folded portion 51, and the fabric main portion 35 is replaced with the fabric main portion 55.

[0044] The sprocket 4 is mounted on the folded portion 31 of the fastener fabric 3 (e.g., by sewing, injection molding, or press-fitting), and the sprocket 6 is mounted on the folded portion 51 of the fastener fabric 5 (e.g., by sewing, injection molding, or press-fitting). Figure 3 In the illustrated example, the fastener element 4 is positioned further back than either the fabric main portion 35 or the folded portion 31, but the present invention is not necessarily limited thereto. The same applies to the fastener element 6.

[0045] The sprockets 4 and 6 engage with each other as the slider 8 advances. (In the example coil-shaped sprocket shown, the engaging heads of the two elements are staggered and engage with each other.) At this point, a boundary line or boundary slit 9 extending in the front-to-back direction is formed between the folded portions 31 and 51. The folded portions 31 and 51 are arranged on both sides of the boundary line or boundary slit 9 (the same also applies to the center line CL of the invisible zipper 1). Similarly, the main chain fabric portions 35 and 55 are arranged on both sides of the boundary line or boundary slit 9 (the same also applies to the center line CL of the invisible zipper 1). When the invisible zipper 1 is closed, whether the folded portions 31 and 51 touch on the center line CL of the invisible zipper 1 depends on the material (whether or not it is raised), the degree of folding, or the shape of the zipper fabrics 3 and 5. Generally speaking, the folded portions 31 and 51 do not touch on the center line CL of the invisible zipper 1, and a boundary slit is formed between them. The sprockets can be seen from the front through the boundary slit, but careful observation is required.

[0046] The engagement of the sprockets 4 and 6 is released by moving the pull head 8 backward. Figure 1 As shown, the slider 8 has a base plate 81, a separation column erected in the center of the width direction of the front part of the base plate 81, a pull-tab mounting portion 82 arranged on the top of the separation column, left and right walls erected on the left and right side edges of the base plate 81, and left and right guide plates 83 and 84 connected to the top of the left and right walls. The slider 8 has two inlets on the left and right sides of the separation column and an engagement opening at the rear of the separation column. The Y-shaped chain tooth passage is defined by the separation column and the left and right side walls. The guide plate 83 is inserted into the gap between the main chain cloth portion 35 formed by the above-mentioned folding and the folded portion 31, and the guide plate 84 is also inserted into the gap between the main chain cloth portion 55 formed by the above-mentioned folding and the folded portion 51, thereby ensuring smooth sliding of the slider 8. In addition, when the slider 8 is at the rearmost position, the second pin portion 12b of the concave component 12 described below is inserted into the slider 8 through its engagement opening. This suppresses displacement of the slider 8 when the first pin portion 11 b of the male member 11 described later is inserted into the slider 8 through the introduction port of the slider 8 .

[0047] The detachable stopper 10 includes a male component 11 and a female component 12, which can be detachably coupled to the male component 11. The male component 11 is adjacent to the sprocket element 4 and fixed to the fastener fabric 3 at a position behind it. The female component 12 is adjacent to the sprocket element 6 and fixed to the fastener fabric 5 at a position behind it. The male and female components 11 and 12 are typically made of resin and manufactured by injection molding, but are not limited to this and may also be made of metal. Furthermore, the female component 12 is not limited to a single component and may also be a two-part assembly.

[0048] Further reference Figures 4 to 8 For explanation. Figure 4 As shown, the convex part 11 has: a first base portion 11a, fixed to at least the front and back sides of the chain cloth main portion 35; a first pin portion 11b, fixed to the folded portion 31, extending in the front-to-back direction at a dorsal position compared to the first base portion 11a; and a first connecting portion 11c, connecting the first base portion 11a and the first pin portion 11b in the form of a guide groove G1 formed between the two.

[0049] In some cases, the first base portion 11a exists on the plane PL (see Figure 3 ) in the flat wing (refer to Figure 4 and Figure 5 ), preferably having a front side 11p and a back side 11q, wherein the front side 11p is at a specific height from the front side 3p of the fastener chain cloth 3 (simply speaking, the front side of the chain cloth main portion 35), and the back side 11q is at a specific height from the back side 3q of the fastener chain cloth 3 (simply speaking, the back side of the chain cloth main portion 35). The thickness of the first base portion 11a is determined by the distance between the front side 11p and the back side 11q. The first pin portion 11b is provided so as to be offset from the plane PL on which the first base portion 11a is arranged toward the back side in the front-back direction. This is because the convex component 11 is fixed within the range of the chain cloth main portion 35 and the folded portion 31. In addition, the first pin portion 11b can be formed in a manner that includes the core rope provided in the folded portion 31. As a result, the mounting strength of the convex component 11 relative to the fastener chain cloth 3 can be improved. In addition, the above-mentioned guide plate 83 can be inserted into the guide groove G1.

[0050] like Figure 5 As shown, the concave component 12 has: a receiving portion 61, which is formed with a receiving groove 61g in the front-to-back direction for inserting and removing the first pin portion 11b; a front side cover 62, which at least partially covers the convex component 11 from the front side when the first pin portion 11b is inserted into the receiving groove 61g; a second base portion 12a, which is fixed to at least the front and back sides of the chain cloth main portion 55; a second pin portion 12b, which is fixed to the folded portion 51 and extends in the front-to-back direction at a dorsal position compared to the second base portion 12a; and a second connecting portion 12c, which connects the second base portion 12a and the second pin portion 12b in the form of a guide groove G2 formed between the two.

[0051] Typically, the receiving portion 61 and the front side cover 62 are arranged facing each other in the front and back directions, thereby constructing a cylindrical portion 63 that at least partially receives the male member 11 (particularly, the rear end or rear half thereof). Figure 4 As shown in the figure, the receiving portion 61 includes a base plate 41 that provides the bottom surface of the receiving groove 61g; a side wall 42 that rises from the base plate 41 on the side farther from the fastener cloth 5; and a wall surface 61f that rises from the bottom surface of the receiving groove 61g on the side closer to the fastener cloth 5 and faces the wall surface 42j of the side wall 42. The width of the receiving groove 61g is defined between the wall surface 42j of the side wall 42 and the wall surface 61f. In some cases, including the illustrated example, the flange that protrudes toward the fastener cloth 5 and is inserted into the guide groove G1 is not provided on the wall surface 42j of the side wall 42. This facilitates insertion of the first pin portion 11b into the receiving groove 61g. Furthermore, even without such a flange, deformation of the male member 11 can be effectively suppressed as described below.

[0052] The front side cover 62 may have a top plate 91 and a side wall 92. The top plate 91 may be opposite to the bottom plate 41 in the front-back direction. The side wall 92 may be opposite to the side wall 42 in the front-back direction. A side window 45 is formed between the side wall 42 and the side wall 92. The side window 45 extends in the front-back direction and has an open end at the front. The first base 11a (for example, the rear end or the rear half) of the convex component 11 is inserted into the side window 45. The side window 45 can be omitted, but in this case, there is a concern that the cylinder 63 will be enlarged. In addition, the above-mentioned wall surface 61f extends toward the front side until it is connected to the top plate 91 and faces the side wall 92 (the stop surface 72 described below).

[0053] Any one or more of the second base portion 12a, the second pin portion 12b, and the second connecting portion 12c, or all of them, may be connected to the cylindrical portion 63. Like the first base portion 11a, the second base portion 12a is a flat-plate-shaped wing portion located on the plane PL. It preferably has a front face 12p and a back face 12q. The front face 12p is located at a specific height from the front face 5p of the fastener fabric 5 (simply, the front face of the fabric main portion 55), and the back face 12q is located at a specific height from the back face 5q of the fastener fabric 5 (simply, the front face of the fabric main portion 55). The second pin portion 12b is disposed so as to be offset from the plane PL in the front-to-back direction relative to the plane PL on which the second base portion 12a is disposed. The front cover 62 is coupled to the front face 12p of the second base portion 12a and may be disposed more anteriorly than the front face 12p of the second base portion 12a (i.e., in a plane further anteriorly than the plane PL). The bottom plate 41 of the accommodating portion 61 may be offset and provided further to the rear side than the second pin portion 12b.

[0054] In this embodiment, the convex member 11 (for example, the first base portion 11a thereof) has a convex portion 71 protruding in the front-back direction, and the front side cover 62 has a stopper surface 72. The stopper surface 72 prevents the convex portion 71 from being displaced in the direction away from the fastener chain 5 when at least the first pin portion 11b is inserted into the receiving groove 61g. Therefore, even if the fastener chain 3, 5 is pulled laterally in the width direction away from the center line CL (or the center plane CP), the convex portion 71 abuts against the stopper surface 72 and prevents the displacement, thereby suppressing the torque RT generated on the first pin portion 11b (see Figure 4 This effectively prevents or suppresses deformation and / or (whole or part) damage to the convex member 11. After the first pin portion 11b is fully inserted into the receiving groove 61g, the convex portion 71 can be partially or completely brought into contact with the stopper surface 72. In some cases, a gap is intentionally created between the two, as described below.

[0055] Preferably, both the protrusion 71 and the stop surface 72 extend in a long strip in the front-to-back direction (in this case, the protrusion 71 becomes a protrusion) to ensure sufficient contact between the two. As shown in the example, the length of the protrusion 71 in the front-to-back direction can be the same as the length of the first pin portion 11b in the front-to-back direction, but this is not necessarily limited to this. In addition, the first pin portion 11b and the protrusion 71 are arranged on opposite sides in the front-to-back direction, but this is not necessarily limited to this. In the example shown, the side wall 92 connected to the top plate 91 has a wall surface on the side of the zipper 5 that provides the stop surface 72, but other structures can also be used. The protrusion 71 can have any cross-sectional shape, such as a rectangle, triangle, semicircle, or semi-ellipse. The stop surface 72 is not limited to a flat surface in a plane perpendicular to the width direction, but can also be an inclined surface inclined at an arbitrary (typically small) angle relative to the plane. In addition, the stop surface 72 can also be a rough surface with a specific surface roughness.

[0056] In some cases, the front cover 62 has a space S1 extending in the front-rear direction and into which the protrusion 71 is inserted, and the stopper surface 72 is one wall surface defining the space S1 . Figures 4 to 6 In the illustrated embodiment, to provide the aforementioned space S1, the front side cover 62 is formed with a groove 73 that is recessed in the front-back direction and extends in the front-back direction. One wall surface of the groove 73 (located farther from the fastener zipper 5) provides the stopper surface 72 (in other words, functions as the stopper surface 72). To be more specific, the front side cover 62 includes a top plate 91 and a side wall 92, and one wall surface of the side wall 92 provides the stopper surface 72. The groove 73 can be defined between the side wall 92 and the wall surface 61f. Needless to say, the stopper surface 72 is not limited to a groove having a bottom surface; it can also be formed by forming a hole or opening without a bottom surface.

[0057] The combination of the convex part 11 and the concave part 12 is as follows: Figures 5 to 8As shown, typically, the rear end or rear half of the male component 11 is received in the cylindrical portion 63 of the female component 12. The front end or front half of the male component 11 is not received in the cylindrical portion 63 but is located in front of the cylindrical portion 63. Figure 6 and Figure 8 In the illustrated state, with the male component 11 and female component 12 engaged, the slider 8 is retracted until it abuts the cylindrical portion 63, with the first and second pin portions 11b and 12b inserted into the slider 8. Furthermore, the first and second connecting portions 11c and 12c are inserted between the guide plates 83 and 84. Meanwhile, the first and second base portions 11a and 12a are both positioned more directly forward of the guide plates 83 and 84 of the slider 8. This means that when the male component 11 (particularly the first base portion 11a) includes the aforementioned protrusion 71, the surface flatness of the concealed zipper 1 is reduced. Therefore, the protrusion 71 is preferably formed to be low in height. For example, the maximum height of the protrusion 71 from the front surface 11p of the first base portion 11a can be less than half or less than one-third of the maximum height of the first pin portion 11b from the back surface 11q of the first base portion 11a. Furthermore, the advantage of improving the mechanical strength of the convex member 11 by forming the convex portion 71 on the first base portion 11 a cannot be ignored.

[0058] Figures 9 to 11 10 is a horizontal cross-sectional view of the detachable stopper 10. Figure 9 As shown, the width W1 of the space S1 can gradually decrease toward the rear. This achieves a balance between ease of insertion of the protrusion 71 into the space S1 and the ability of the stop surface 72 to stop the protrusion 71. In this regard, the female component 12 (e.g., the top plate 91 or the tubular portion 63) can include a rearwardly recessed recess 75 that can be in close contact with the rear end 71c of the protrusion 71. Additionally or alternatively, the female component 12 (e.g., the top plate 91 or the tubular portion 63) can include at least one guide surface 76 that guides the rear end 71c of the protrusion 71. This guide surface 76 can be inclined so as to move away from the fastener fabric 5 (or the centerline CL) as it extends rearward. The angle θ formed by the acute angle between the plane PL9 containing the guide surface 76 and the centerline CL of the concealed zipper 1 can be less than 45°. Furthermore, in this regard, the width W71 of the protrusion 71 can gradually decrease toward its rear end 71c.

[0059] The length of the stopper surface 72 in the front-back direction may be 1 / 3 or more of the length of the convex portion 71 in the front-back direction (see Figure 9 ), thereby promoting the convex portion 71 to be fully restrained by the restraining surface 72. Figure 9As shown in the figure, the stop surface 72 may include a main stop surface 72a, an intermediate surface 72b, and an auxiliary stop surface 72c that is consistent with one side wall surface of the above-mentioned recessed portion 75. The main stop surface 72a extends from near the rear end of the protrusion 71 to near the middle thereof in a manner having a length sufficient to stop the protrusion 71. The main stop surface 72a is formed as a plane perpendicular to the width direction, and may also be inclined relative to this plane. The intermediate surface 72b is formed between the main stop surface 72a and the recessed portion 75 (auxiliary stop surface 72c), thereby ensuring the continuity of the stop surface 72. The intermediate surface 72b is inclined so as to approach the center line CL as it extends rearward from the rear end of the main stop surface 72a. The auxiliary stop surface 72c is a contact surface that contacts the rear end 71c of the protrusion 71 when the first pin portion 11b is fully inserted into the receiving groove 61g. The stopper surface 72 may or may not be in contact with the protrusion 71 in a state where the first pin portion 11 b is completely inserted into the receiving groove 61 g .

[0060] When the male member 11 is fully inserted into the cylindrical portion 63, a slight gap (in the width direction) exists between the male portion 71 and the main stop surface 72a. The stop surface 72 is provided to prevent deformation of the male member 11 during horizontal pulling, and also to create a gap between the male portion 71 and the stop surface 72. This gap between the male portion 71 and the stop surface 72 facilitates the connection between the female member 12 and the male member 11.

[0061] Figure 10 and Figure 11 For reference only. Figure 10 As shown in FIG. 1 , the first base portion 11a is not entirely accommodated in the cylindrical portion 63. Figure 11 As shown in FIG. 1 , the first pin portion 11b can abut against the wall surface of the housing portion 61 at two locations shown by dotted circles. Other structures can also be adopted. Figure 11 It is clear that the receiving groove 61g can be formed to penetrate the cylindrical portion 63 in the front-back direction. This promotes the discharge of liquid or dust that has entered the cylindrical portion 63.

[0062] Reference Figure 12The steps for closing the invisible zipper 1 are described. The slider 8 (not shown) is adjacent to the front of the concave component 12. The first pin portion 11b of the male component 11 is inserted into the slider 8 through the left side inlet of the slider 8. At this time, the guide plate 83 is inserted into the guide groove G1 between the first pin portion 11b and the first base portion 11a. When the first pin portion 11b of the male component 11 is further inserted into the slider 8, the first pin portion 11b is inserted into the receiving groove 61g. In addition, synchronously with this, the male portion 71 of the male component 11 is inserted into the space S1 (groove 73 in the example shown). In the case where the guide surface 76 is provided as described above, the rear end 71c of the male portion 71 slides rearward on the guide surface 76, and the male portion 71 moves backward while rotating clockwise. Finally, the rear end 71c of the male portion 71 is engaged and positioned in the above-mentioned concave portion 75. The above-mentioned advantages are obtained by providing a space between the stopper surface 72 (particularly the main stopper surface 72 a ) and the convex portion 71 .

[0063] The above description will readily explain the manufacturing method of the concealed zipper 1 to those skilled in the art. For example, a first fastener tooth is attached to a first fastener fabric, and then a male component is injection-molded onto the first fastener fabric. A second fastener tooth is attached to a second fastener fabric, and then a female component is injection-molded onto the second fastener fabric. Alternatively, compression bonding of metal components serving as the male and female components may be employed instead of injection molding.

[0064] For reference, Figure 13 The convex portion 71 is formed by forming the concave portion 101 in the convex member 11, and the stopper surface 72 is formed by forming the convex portion 102 in the front side cover 62. Typically, the convex portion 102 can be loosely fitted into the concave portion 101. For reference, Figure 14 A modification example is shown in which the stopper surface 72 is provided by the wall surface of a hole or opening instead of the wall surface of a groove. In any modification example, as long as the same features as above are provided, the same effects as above can be obtained.

[0065] Based on the above teachings, those skilled in the art may make various changes to the various embodiments and features. The symbols added in the claims are for reference only and should not be used to limit the scope of the claims. The protrusion 71 may have other various shapes such as a cylindrical button, a triangular pyramid, a quadrangular pyramid or a cone. The protrusion 71 protrudes toward the front side in all the illustrated examples, but it can also be set to protrude toward the back side. That is, it is also possible to set another cover on the convex part 11 to cover the front side cover 62 of the concave part 12 from the front side, and set a convex portion protruding toward the back side on the other cover.
