Abstract
Description
Technical Field
[0001] This utility model relates to a cord fastener for holding a cord in place by inserting a plug into a socket through which a cord is inserted. Background Technology
[0002] Conventionally, a cord fastener is known in which a cord is pressed and held against the inner surface of a socket by inserting a plug into the socket through which the cord is inserted (Reference 1: See International Publication No. 2023 / 017566). The socket has a pair of surface portions forming the insertion port, and a cord mounting portion is formed on one of the surface portions, perpendicular to that surface portion. The cord mounting portion is arranged away from the insertion port of the socket in the thickness direction of the surface portion, and a cord member is wound around the cord mounting portion, which is fixed near a cord-threading hole in an opening such as a bag. Furthermore, a pair of operating portions are provided on the plug, which are arranged outwards and parallel to each of the pair of surface portions of the socket.
[0003] In this rope fastener, the distance between the plug and the socket is widened by holding and pulling the operating part with one hand, so that the rope changes from a holding state to a sliding state.
[0004] However, in the cord fastener described in Document 1, although the cord mounting part is arranged away from the insertion port of the socket in a way that is in the thickness direction of the surface part, the aforementioned pair of operating parts, which are held and pulled by one hand, can stabilize the orientation of the cord fastener when the plug is pulled out of the socket, even if the cord fastener generates a rotational torque, so the cord fastener can be operated smoothly.
[0005] However, for example, if the strap mounting part is provided on the plug instead of the aforementioned pair of operating parts, when the plug is pulled out of the socket by pulling the strap that is wound on the strap mounting part of the plug, the configuration relationship between the strap mounting part of the socket and the strap mounting part of the plug will cause the strap fastener to generate a rotational torque. At this time, the strap fastener itself is not held by fingers or the like, so the orientation of the strap fastener becomes unstable, and there is a possibility that the strap fastener is difficult to operate smoothly. Utility Model Content
[0006] The purpose of this invention is to provide a cord fastener that improves the operability of separating a plug from a socket.
[0007] (1) One aspect of the present invention relates to a cord fastener, comprising: a socket having: a socket body having a front portion and a back portion having an insertion port formed through it, and a socket side connecting rod connected to the socket body; and a plug having: a plug body having: a plug body having been movably inserted into the insertion port in an insertion direction toward the socket and having a cord clamped between the plug body and the socket body, and a plug side connecting rod connected to the plug body, wherein the socket side connecting rod and the plug side connecting rod are positioned on the back side relative to the insertion port in a front-back direction orthogonal to the insertion direction.
[0008] (2) In this method, the position of the plug-side connecting rod may also be configured to be on the surface side and below the rope body, which is different from the position of the socket-side connecting rod.

[0010] (4) In this embodiment, a front guide groove along the insertion direction may be formed on the inner surface of the front part, and a back guide groove along the insertion direction may be formed on the inner surface of the back part. The plug body part has a corresponding guided part, such that the guided part is guided by the front guide groove and the back guide groove respectively. The width dimensions of the front guide groove and the back guide groove are different from each other in the width direction orthogonal to the insertion direction.
[0011] (5) In this method, the length of the surface portion in the intersecting direction may be larger than the length of the back portion in the intersecting direction.
[0012] (6) In this embodiment, the surface portion may be formed such that as it moves toward the insertion side of the plug in the interlocking direction, the width dimension of the surface portion in the width direction orthogonal to the interlocking direction gradually increases.
[0013] (7) In this embodiment, a protrusion protruding toward the surface may also be formed on the surface portion at a position opposite to the insertion side of the plug in the insertion direction.
[0014] (8) In this embodiment, the socket may also have a side portion connected to the surface portion and the back portion, and the end of the side portion on the insertion side of the plug forms the bottom surface of a recess formed in cooperation with the surface portion and the back portion.
[0015] According to this utility model, a cord fastener can be provided that improves the operability of separating a plug from a socket. Attached Figure Description

[0025] (Structure of this embodiment)
[0026] The embodiments of this utility model will now be described with reference to the accompanying drawings.
[0027] exist Figures 1 to 5In this embodiment, the cord stopper 1 can be fixed at any position relative to a cord 2 provided along the opening of an item such as a backpack. By adjusting the fixed position relative to the cord 2, the opening of the item can be closed or opened. The cord stopper 1 includes a socket 11 and a plug 12 inserted into the socket 11. The socket 11 includes a socket body 20 with a through-hole 10; and a socket-side connecting rod 30 connected to the socket body 20, with a strip-shaped band 3 wound around and attached as a connected element, the end of which is fixed to an item such as a backpack. The plug 12 includes a plug body 40 that holds the cord 2 between itself and the socket body 20; and a plug-side connecting rod 50 connected to the plug body 40, with a strip-shaped band 4 wound around it as a connected element. In addition, the end of the band 4 can also be fixed to the item.
[0028] In the following description, for ease of explanation, the front-to-back direction of the cord fastener 1 (the insertion direction of the plug 12 relative to the socket 11) is defined as the X-axis direction, the width direction (left-to-right direction) of the cord fastener 1 is defined as the Y-axis direction, and the front-to-back direction (thickness direction) of the cord fastener 1 is defined as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are orthogonal to each other. Furthermore, Figure 3 and Figure 5 The diagram shows the insertion state where the plug 12 is deeply inserted into the socket 11, and the withdrawal state where the plug 12 is pulled out of the socket 11 along the X-axis direction. Figure 4 The diagram shows a perspective view of the cord fastener 1 from the front side and a perspective view of the cord fastener 1 from the back side. The plug 12 in the pulled-out state is represented by a solid line, and the plug 12 in the inserted state is represented by a double-dotted line.
[0029] (socket)
[0030] Socket 11 Figure 6 and Figure 7 As shown separately, it is made of synthetic resin and is integrally molded.
[0031] The socket body 20 includes: a surface portion 21 and a back portion 22 facing each other in the Z-axis direction; and a pair of side portions 23 connected to the side edges of the surface portion 21 and the back portion 22 and facing each other in the Y-axis direction.
[0032] The surface portion 21 is flattened along the X-axis and Y-axis directions. The length of the surface portion 21 in the X-axis direction is larger than that of the back portion 22 in the X-axis direction, and it extends in the X-axis direction to a position further rearward than the back portion 22 (the insertion side of the plug 12). In addition, the width of the surface portion 21 in the Y-axis direction gradually increases from the front side (the side opposite to the insertion side of the plug 12) toward the rear side in the X-axis direction.
[0033] A trapezoidal protrusion 211 is formed on the surface portion 21. The protrusion 211 protrudes from the outer surface 21A of the surface portion 21 along the Z-axis direction at the front side position in the X-axis direction. The protrusion 211 is formed along the front end of the surface portion 21.
[0034] In addition, such as Figure 5 and Figure 7 As shown, a groove-shaped surface guide groove 212 along the X-axis direction is formed on the inner surface 21B of the surface portion 21. A surface abutting portion 213 is formed in the surface guide groove 212, which abuts against the surface guided portion 411 of the plug 12 in the X-axis direction. The surface abutting portion 213 restricts the plug 12 from moving rearward beyond a predetermined position by abutting against the guided portion 411.
[0035] The back portion 22 is flattened along the X-axis and Y-axis directions. The width of the back portion 22 in the Y-axis direction gradually increases from the front side to the rear side in the X-axis direction. The left and right portions 224 of the rear end of the back portion 22 are positioned on the front side compared to the central portion 225 of that end, and an inclined surface 226 is formed between the left and right portions 224 and the central portion 225 to connect them. The socket-side connecting rod 30 is connected to the front end of the back portion 22.
[0036] Additionally, a groove-shaped back guide groove 222 along the X-axis direction is formed on the inner surface 22B of the back side portion 22. A back abutment portion 223 is formed in the back guide groove 222, which engages with the back guide portion 421 of the plug 12 in the X-axis direction. The back abutment portion 223 restricts the plug 12 from moving backward beyond a predetermined position by abutting with the back guide portion 421.
[0037] Here, the width dimensions W1 of the front guide groove 212 in the Y-axis direction and the width dimension W2 of the back guide groove 222 in the Y-axis direction are different from each other, and in this embodiment, W1 < W2. In addition, the front guided portion 411 of the plug 12 has a width dimension corresponding to the width dimension W1 of the front guide groove 212, and the back guided portion 421 has a width dimension corresponding to the width dimension W2 of the back guide groove 222. Therefore, even if the plug 12 is inserted into the socket 11 with the back side upside down, for example, the back guided portion 421 of the plug 12 will collide with the socket 11, making it impossible to insert the plug 12 into the socket 11 when the back side is upside down.
[0038] The side portion 23 is formed in a plate shape along the X-axis and Z-axis directions, respectively. The length dimension of the side portion 23 in the X-axis direction is smaller than the length dimension of the back portion 22. The rear end of the side portion 23, together with the inner surfaces 21B and 22B of the surface portion 21 and the back portion 22, forms a recess 24 that is recessed towards the front side of the socket 11. The rear end of the side portion 23 constitutes the bottom surface of the recess 24, and the inner surfaces 21B and 22B constitute a pair of side surfaces of the recess 24.
[0039] In the aforementioned socket 11, the surface portion 21, the back portion 22, and a pair of side portions 23 are formed into a generally rectangular cylindrical shape, and an insertion port 10 extending through in the X-axis direction is formed. Two ropes 2 are inserted into the insertion port 10.
[0040] With the aforementioned front abutment portion 213 and back abutment portion 223, by applying a large force in the X-axis direction to the plug 12 and inserting it into the socket 11, the socket 11 itself undergoes elastic deformation, causing the front guided portion 411 of the plug 12 to pass over the front abutment portion 213 and the back guided portion 421 to pass over the back abutment portion 223, thereby combining the socket 11 and the plug 12. The plug 12 can move a predetermined amount relative to the socket 11 in the X-axis direction.
[0041] Furthermore, the state in which the plug 12 is deeply inserted into the socket 11 along the X-axis direction is defined as the insertion state, and the state in which the plug 12 is pulled out relative to the socket 11 along the X-axis direction is defined as the pull-out state.
[0042] The socket-side connecting rod 30 is formed in the shape of a "コ" and includes: a pair of sides 31 facing each other in the Y-axis direction; and a rectangular rod-shaped connecting part 32 connected to the pair of sides 31 and extending along the Y-axis direction, with a strap 3 wound around the connecting part 32.
[0043] In the socket-side connecting rod 30, a pair of side portions 31 protrude from the front end (the end opposite to the plug 12) in the X-axis direction of the back portion 22 toward the back side along the Z-axis direction, and the connecting portion 32 is arranged such that it is away from the outer surface 22A of the back portion 22 in the Z-axis direction. The socket-side connecting rod 30 and the back portion 22 cooperate to form a connecting hole 35 through which the strap 3 passes.
[0044] (plug)
[0045] Plug 12 Figure 8 and Figure 9 As shown separately, it is made of synthetic resin and is integrally molded.
[0046] The plug body 40 is formed to extend along the X-axis direction and has a surface 41, a back surface 42, a pair of side surfaces 43, a front surface 44, and a rear surface 45. The pair of side surfaces 43 are connected to the two side edges of the surface 41 and the back surface 42, and are inclined relative to the X-axis direction as they move away from each other in the Y-axis direction from the front side toward the rear side in the X-axis direction. The front surface 44 is connected to the front edge of the surface 41, the back surface 42, and the pair of side surfaces 43 on the front side in the X-axis direction, and the rear surface 45 is connected to the rear edge of the surface 41, the back surface 42, and the pair of side surfaces 43 on the rear side in the X-axis direction.
[0047] A surface-side guided portion 411 (guided portion) protruding towards the surface along the Z-axis direction is formed at the front end of the surface 41, and a back-side guided portion 421 (guided portion) protruding towards the back along the Z-axis direction is formed at the front end of the back surface 42.
[0048] The surface-guided portion 411 is formed in a shape corresponding to the aforementioned surface-guided groove 212, and has a width corresponding to the width W1 of the surface-guided groove 212. It is guided by the surface-guided groove 212 along the X-axis direction. In addition, the surface-guided portion 411 has an inclined surface 412 that slopes towards the back side 42 as it faces forward. Therefore, when the plug 12, which is in a detached state from the socket 11, is assembled into the socket 11, the inclined surface 412 slides against the surface-abutting portion 213. Thus, compared to the case where the inclined surface 412 is not formed, the surface-guided portion 411 can more easily pass over the surface-abutting portion 213 of the socket 11.
[0049] The back-side guided portion 421 is formed in a shape corresponding to the aforementioned back-side guide groove 222, and has a width corresponding to the width W2 of the back-side guide groove 222. It is guided by the back-side guide groove 222 along the X-axis direction. In addition, the back-side guided portion 421 has an inclined surface 422 that slopes towards the surface 41 as it moves towards the front. Therefore, by sliding the inclined surface 422 in the separated state from the socket 11, the front-side guided portion 411 can more easily pass over the back-side contact portion 223 of the socket 11 compared to the case where the inclined surface 422 is not formed.
[0050] A pair of side surfaces 43 are each configured with a concave-convex shape as a rope holding portion 43A in the X-axis direction, and are arranged facing the inner surface 23B of the side surface 23 of the socket 11 in the Y-axis direction. The rope holding portion 43A holds the rope 2 by clamping it between the rope 2 and the inner surface 23B when the plug 12 is inserted into the socket 11. In addition, the rope holding portion 43A releases the clamping when the plug 12 is pulled out relative to the socket 11, so that the rope 2 can move relative to the rope fastener 1 in the X-axis direction. Furthermore, 23A is the outer surface of the side surface 23.
[0051] The plug-side connecting rod 50 includes: a pair of side portions 51 facing each other in the Y-axis direction; a rectangular rod-shaped connecting portion 52 connected to the pair of side portions 51 and extending along the Y-axis direction; and a connecting portion 53 that connects the front ends of the pair of side portions 51 in the X-axis direction to the rear portions of the pair of side portions 23 of the socket body 20, having a width dimension equal to the width dimension of the socket 11 in the Y-axis direction. The pair of side portions 51 and the connecting portion 52 form a "コ" shape. The side portions 51 are along the X-axis direction, and the connecting portion 52 is located rearward relative to the plug body 40 and is wound and connected with a strap 4. The aforementioned pair of side portions 51 and connecting portion 52 forming the "コ" shape are positioned in the Z-axis direction closer to the surface than the socket-side connecting rod 30 and below the cord 2. In the plug-side connecting rod 50, one of the pair of side portions 51 is disposed on one outer side of the plug-side connecting rod 50 in the Y-axis direction, and the other side of the pair of side portions 51 is disposed on the other outer side of the plug-side connecting rod 50 in the Y-axis direction. The pair of side portions 51 are respectively disposed on the outer side of the plug body portion 40 in the Y-axis direction, and the connecting hole 46 is wider in the Y-axis direction compared to the plug body portion 40.
[0052] A pair of connecting portions 53 have inclined surfaces 531, which are formed to extend along the Y-axis direction from the rear side portion 23 of the plug body portion 40 and are inclined to the rear side relative to the Y-axis direction as they move outward toward the Y-axis direction. One of the inclined surfaces 531 of the pair of connecting portions 53 guides one of the two ropes 2 that pass through the insertion port 10 formed in the socket 11 outward in the Y-axis direction, and the other inclined surface 531 of the pair of connecting portions 53 guides the other of the two ropes 2 that pass through the insertion port formed in the socket 11 outward in the Y-axis direction. Thus, the two ropes 2 are guided by the inclined surfaces 531 respectively and are therefore arranged above the pair of side portions 51 in a way that they are far apart from each other in the Y-axis direction.
[0053] The plug-side connecting rod 50 works in conjunction with the rear surface 45 of the plug body 40 to form a connecting hole 46 through which the tape 4 passes.
[0054] In the aforementioned case of assembling the plug 12 into the socket 11, firstly, two cords 2 are threaded through the insertion port 10 of the socket 11, and while positioning the plug body 40 between the two cords 2, the plug body 40 is inserted into the insertion port 10 of the socket 11 from the front surface 44 side. Next, by pressing the plug 12 along the X-axis direction, the front-side guided portion 411 and the back-side guided portion 421 are moved forward past the front-side abutment portion 213 and the back-side abutment portion 223. Thus, the plug 12 is assembled into the socket 11. At this time, the two cords 2 are positioned in the clamping space formed between the inner surfaces 23B of a pair of side surfaces 23 of the socket 11 and the cord holding portions 43A in a pair of side surfaces 43 of the plug 12. The plug 12 is positioned such that it can move a predetermined amount along the X-axis within the range where the front guide portion 411 and the back guide portion 421 cannot move backward beyond the front abutment portion 213 and the back abutment portion 223. When the plug 12 is inserted deeply into the socket 11 along the X-axis, because the clamping space is narrow in the Y-axis direction, the two ropes 2 are firmly clamped by the inner surface 23B of the socket 11 and the rope holding portion 43A of the plug 12. This results in the rope fastener 1 being fixed at any position on the rope 2, thereby maintaining the opening of items such as backpacks in a closed or open state. Furthermore, when the plug 12 is pulled out relative to the socket 11 along the X-axis, the clamping space increases in the Y-axis direction, thus loosening the clamping of the rope 2. As a result, the rope 2 becomes able to slide relative to the rope fastener 1 along the X-axis. By adjusting the position of the rope fastener 1 relative to the rope 2, the opening of items such as backpacks can be closed or opened.
[0055] In the aforementioned cord fastener 1, both the socket-side connecting rod 30 and the plug-side connecting rod 50 (especially the "ko"-shaped part) are positioned on the back side relative to the insertion port 10 in the Z-axis direction. Therefore, for example, when the plug 12 is pulled out of the socket 11 in the X-axis direction by pulling one of the straps 3 and 4 connected to the socket-side connecting rod 30 and the plug-side connecting rod 50 along the X-axis direction (here, by pulling strap 4), the rotational torque generated by the cord fastener 1 can be suppressed, thus stabilizing the orientation of the cord fastener 1. As a result, the operation of the cord fastener 1 can be performed smoothly.
[0056] (Modified Example)
[0057] In the described embodiment, the plug-side connecting rod 50 is positioned closer to the surface and below the rope body 2 than the socket-side connecting rod 30, but this is not a limitation. It is acceptable as long as it is within the range that can suppress the rotational torque generated by the rope fastener 1. For example, the plug-side connecting rod 50 may also be positioned in the Z-axis direction at the same position as the socket-side connecting rod 30, or at a lower position than the socket-side connecting rod 30.
[0058] In the embodiment described, the plug-side connecting rod 50 has an inclined surface 531, which is formed to extend from the plug body portion 40 along the Y-axis direction and to be inclined to the back side relative to the Y-axis direction as it moves outward toward the Y-axis direction. However, it is not limited to this. Even if the inclined surface 531 is not provided, the structure of the aforementioned inclined surface 531 can be omitted as long as the rope body 2 is wrapped around in a way that allows the rope fastener 1 through which the rope body 2 is inserted.
[0059] In the described embodiment, the width dimensions of the front guide groove 212 and the back guide groove 222 of the socket 11 are in a relationship of W1 < W2, but are not limited to this; for example, W1 > W2. Furthermore, the width dimensions W1 and W2 of the front guide groove 212 and the back guide groove 222 are different from each other, but are not limited to this; the shapes of the front guide groove 212 and the back guide groove 222 themselves may be different from each other. In this case, the front guided portion 411 and the back guided portion 421 of the plug 12 are formed to have width dimensions or shapes corresponding to the front guide groove 212 and the back guide groove 222.
[0060] In the embodiment described, the length dimension of the surface portion 21 of the socket 11 in the X-axis direction is larger than the length dimension of the back portion 22 in the X-axis direction, but it is not limited to this. For example, if it is desired that the plug 12 is exposed on the surface, the length dimension of the surface portion 21 may be the same as the length dimension of the back portion 22 or smaller than the length dimension of the back portion 22.
[0061] In the embodiment described, the surface portion 21 of the socket 11 is formed such that its Y-axis dimension gradually increases in the X-axis direction from the front side to the rear side (the insertion side of the plug 12), but it is not limited to this. It may also have the same width dimension from the front side to the rear side, or it may have the dimension gradually decrease from the front side to the rear side.
[0062] In the embodiment described above, a protrusion 211 protruding toward the surface is formed on the front side (opposite to the insertion side of the plug 12) in the X-axis direction of the surface portion 21. However, this is not a limitation. Even if the protrusion 211 is not provided, the structure of the protrusion 211 can be omitted as long as the socket 11 can be held stably enough during the operation of the cord fastener.
[0063] In the embodiment described, the surface portion 21, the back portion 22, and the side portion 23 form a recess 24 on the rear side of the socket 11, and the end of the side portion 23 forms the bottom surface of the recess 24. However, even if the recess 24 is not formed, the structure of the recess 24 can be omitted as long as the rope body 2 is wound around the rope fastener 1 in an operable manner.
[0064] In the embodiment described, the cord holding portion 43A is formed on the side surface 43 of the plug 12, but it is not limited thereto. For example, the cord holding portion 43A formed on the side surface 43 may be replaced by the cord holding portion 43A formed on the side surface 23B of the socket 11, or a cord holding portion with a concave-convex shape may be formed on the inner surface 23B of the side surface 23 of the socket 11, in addition to the cord holding portion 43A formed on the side surface 43.
[0065] In the embodiment described, the rope fastener 1 is used as a component for inserting a rope 2 that is provided along the opening of an item such as a backpack. In addition, it can also be used as a component for inserting a rope 2 that is provided in a bag, clothing, cold-weather gear, etc.
[0066] (Effects)
[0067] (1) The cord fastener 1 of this embodiment includes: a socket 11, which includes: a socket body 20 having a surface portion 21 and a back portion 22 and having a through-hole 10 formed therethrough; a socket side connecting rod 30 connected to the socket body 20; and a plug 12, which includes: a plug body 40 being movably inserted into the through-hole 10 in an insertion direction (X-axis direction) toward the socket 11 and clamping the cord 2 between it and the socket body 20; and a plug side connecting rod 50 connected to the plug body 40, wherein the socket side connecting rod 30 and the plug side connecting rod 50 are positioned on the back side relative to the through-hole 10 in a front-back direction (Z-axis direction) orthogonal to the insertion direction.
[0068] According to the rope fastener 1 of this embodiment, the socket-side connecting rod 30 and the plug-side connecting rod 50 are positioned on the back side relative to the insertion port 10 of the socket 11, as described above. Therefore, it can be configured so as not to obstruct the rope 2 inserted into the insertion port 10. Moreover, it forms a structure in which, for example, compared to the case where the socket-side connecting rod 30 is positioned on the back side and the plug-side connecting rod 50 is positioned along the insertion port 10 or on the surface side in the X-axis direction, the rope fastener 1 is less likely to generate rotational torque when pulling either of the connected bodies such as the strips 3 and 4 connected to the socket-side connecting rod 30 and the plug-side connecting rod 50 to separate the socket 11 and the plug 12 in the X-axis direction, thereby improving the operability when separating the plug 12 from the socket 11.
[0069] Furthermore, since the plug-side connecting rod 50 is positioned on the back side relative to the insertion port 10 of the socket 11, there is no need to provide an operation part or the like on the outside of the surface portion 21 of the socket 11. As a result, the area of the outer surface 21A of the surface portion 21 of the socket body portion 20 can be increased, thereby forming a structure that makes it easy to apply various markings or the like to the surface portion 21.
[0070] (2) In the rope fastener 1 of this embodiment, the plug-side connecting rod 50 is positioned on the surface side and below the rope body 2, which is more than the position of the socket-side connecting rod 30.
[0071] With this structure, the plug-side connecting rod 50 is positioned close to the plug body 40, thus enabling the plug 12 itself to be miniaturized. Furthermore, the plug-side connecting rod 50 is positioned below the rope 2, thereby allowing the rope 2 to be guided along the X-axis direction via the plug-side connecting rod 50.
[0072] (3) In the cord fastener 1 of this embodiment, two cords 2 are inserted into the socket 11, and the plug 12 is disposed between the two cords 2 in a width direction (Y-axis direction) orthogonal to the insertion direction. The plug-side connecting rod 50 has an inclined surface 531, which is formed to extend from the plug body 40 along the Y-axis direction and tilts towards the back side relative to the Y-axis direction as it moves outward toward the Y-axis direction.
[0073] With this structure, a portion of the rope 2 extending from the insertion port 10 of the socket 11 toward the plug 12 can be guided outward in the Y-axis direction so that the two ropes 2 are far apart from each other.
[0074] (4) In the cord fastener 1 of this embodiment, a front guide groove 212 along the X-axis direction is formed on the inner surface 21B of the surface portion 21, and a back guide groove 222 along the X-axis direction is formed on the inner surface 22B of the back portion 22. The plug body portion 40 has a guided portion (front guided portion 411, back guided portion 421) with corresponding shapes so that the guided portion is guided by the front guide groove 212 and the back guide groove 222 respectively. In the Y-axis direction, the width dimensions W1 and W2 of the front guide groove 212 and the back guide groove 222 are different from each other.
[0075] With this structure, the width dimensions of the face-side guide groove 212 and the back-side guide groove 222 are different from each other. Therefore, for example, when the plug 12 is to be inserted into the socket 11 with the back side facing upside down, it cannot be inserted because either the face-side guide groove 212 or the back-side guide groove 222 does not match the width dimensions of either the back-side guided portion 421 or the face-side guided portion 411. Thus, it is possible to prevent the plug 12 from being mistakenly inserted into the socket 11 with the back side facing upside down.
[0076] (5) In the rope fastener 1 of this embodiment, the length dimension of the surface portion 21 in the X-axis direction is formed to be larger than the length dimension of the back portion 22 in the X-axis direction.
[0077] Based on this structure, a structure is formed that increases the area covered by the surface portion 21 of the socket 11 of the plug 12, making the plug 12 less conspicuous on the surface, and the area of the outer surface 21A of the surface portion 21 of the socket 11 is made larger, thereby enabling the application of larger markings and other designs to the surface portion to improve design.
[0078] (6) In the cord fastener 1 of this embodiment, the surface portion 21 is formed such that its width dimension in the Y-axis direction gradually increases as it faces the insertion side of the plug 12 in the X-axis direction.
[0079] With this structure, the area of the outer surface 21A of the surface portion 21 of the socket 11 can be made larger, and larger markings can be applied to the surface portion 21, thereby improving the design.
[0080] (7) In the cord fastener 1 of this embodiment, a protrusion 211 protruding toward the surface is formed on the surface portion 21 at a position opposite to the insertion side of the plug 12 in the X-axis direction.
[0081] With this structure, when operating the cord fastener 1, especially when pulling the plug 12 out of the socket 11 along the X-axis direction, the socket 11 can be stably held by placing fingers on the aforementioned protrusion 211, thereby enabling smoother operation of the cord fastener 1.
[0082] (8) In the cord fastener 1 of this embodiment, the socket 11 has a side portion 23 connected to the surface portion 21 and the back portion 22, and the end of the side portion 23 on the insertion side of the plug 12 forms the bottom surface of the recess 24 formed in cooperation with the surface portion 21 and the back portion 22.
[0083] According to this structure, by forming the aforementioned recess 24, the area through which the rope 2 extending from the insertion port 10 of the socket 11 passes along the Y-axis can be increased.
