Description

Technical Field

[0001] The present invention relates to a rope stopper that allows a rope to pass through and can be fixed at any position on the rope. Background Technology

[0002] Conventional rope stoppers exist, which are installed at any position on the rope and maintain a predetermined length by adjusting the rope's extension. Such rope stoppers come in various shapes and forms; for example, the rope buckle in Patent Document 1 includes: a hollow retaining body; and a fastening member configured to move relative to the retaining body and hold the rope passing through it. The fastening member has a central toothed portion, with multiple serrated, inclined teeth formed on both sides. The inclination direction of the serrations is opposite to the direction in which the rope passing through the retaining body moves in a relaxed manner. In other words, the teeth are shaped such that the rope can only move in the tightening direction when the fastening member is in a tightened state. A guide portion is provided above the inclination direction of the teeth, allowing insertion into a guide passage in the retaining body. A finger hook portion protrudes above the guide portion for easy hooking of the fingers during movement of the fastening member.

[0005] Patent Document 1: Japanese Patent Application Publication No. 11-309001 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] In the aforementioned context, when tying a rope, the finger hook portion needs to be operated to move the fastening member in the direction of the moving rope, switching from a locked state where the rope is secured to a released state where the rope can move. Therefore, the operation is complex, requiring two actions: moving the fastening member to switch to the released state and moving the retaining body relative to the rope. Furthermore, the system consists of three components: the retaining body, the fastening member, and the end cap, resulting in a large number of parts, each with an upward-protruding finger hook portion, and a complex shape. The fastening member has a toothed portion that is relatively long in one direction, requiring the retaining body to accommodate the sufficient length of the toothed portion. Additionally, the end cap is installed at the end of the retaining body, thus increasing its overall size.

[0008] The present invention was made in view of the problems of the above-mentioned background art, with the aim of providing a rope stopper that is small and simple in shape and easy to use with simple operation.

[0009] Solution for solving the problem

[0010] This invention relates to a rope stopper, comprising: a socket having an inner fitting portion for a rope to pass through; and a plug for pressing and holding the rope inserted into the socket against the inner wall surface of the socket. The socket is a cylindrical body surrounded by a pair of surface portions facing each other at predetermined intervals and a pair of side portions located on the side edges of the pair of surface portions and opposite to each other, wherein the fitting portion is provided. One of the pair of opposing openings of the cylindrical body is an insertion port for inserting and installing the plug and for the rope to pass through, and the other opening is a through port for the rope to pass through together with the insertion port. A sliding groove is provided on the surface portion, one end of the sliding groove communicating with the insertion port and the other end located on the through port side. A guide recess is provided on the inner surface of the surface portion, one end of the guide recess located on the through port side, the guide recess extending toward the sliding groove and the other end reaching the inner wall surface of the plug. Near the end of the sliding groove, the portion between the end of the sliding groove and the end of the guide recess forms a stop portion. The plug is provided with: a retaining portion that protrudes in the direction of the cord's penetration within the fitting portion; a pair of guide portions located at the base end of the retaining portion, intersecting the protrusion direction of the retaining portion, and protruding towards a pair of surface portions respectively; and a pair of operating portions continuous with the top end of the guide portions, which are plates having surfaces parallel to the protrusion direction of the retaining portion. When the socket and the plug are assembled, the operating portions are located inside the outline of the surface portions. The plug is provided with a retaining protrusion at the top end of the retaining portion on the side opposite to the base end of the retaining portion, which slides and engages with the guide recess. The plug is configured such that the retaining protrusion can slide along the guide recess between the stop portion and the through opening, and the guide portion can engage with the sliding groove and move. For the rope stopper, if the plug is moved toward the through-hole, the rope is fixed between the inner wall of the socket and the plug. If the plug is moved away from the through-hole, the space between the inner wall of the socket and the plug widens, and the rope can slide.

[0011] With the rope passing through the socket and the plug assembled with the socket, at any position in the direction in which the plug can slide, the projected shape of the operating part onto the surface is located inside the outline of the surface.

[0012] The portion of the surface of the socket between the stop portion at the end of the sliding groove and the through-hole forms a finger placement portion for placing a finger during operation. The finger placement portion includes a socket finger hook portion protruding from the surface portion along the side edge of the through-hole.

[0013] At least a portion of the projected shape in the thickness direction of the surface portion of the guide recess on the inner surface of the finger placement portion overlaps with the retaining portion of the plug.

[0014] The finger placement portion is provided at a ratio of 0.3 to 0.5 relative to the length of the cord in the penetrating direction of the socket. With the cord penetrating the socket and the plug assembled with the socket, even if the plug is moved to any slidable position, the finger placement portion of the socket is exposed from the operating part at a ratio of 0.2 to 0.4 relative to the length of the cord in the penetrating direction of the socket.

[0015] A receptacle finger hook protruding from the surface is formed on the surface portion of the receptacle along the side edge of the through opening. Alternatively, an operating finger hook may be formed on the end of the operating portion of the plug on the side opposite to the protruding direction of the retaining portion.

[0016] Alternatively, a mounting portion may be provided on the surface of the socket that forms the through opening.

[0017] The effects of the invention

[0018] The cord stopper of the present invention has a small and simple shape, making it easy to use with simple operation. When opening or closing the opening of a bag or similar object, the socket and plug can be held together with one hand, eliminating the need to switch them or hold them separately during opening and closing. This allows for intuitive and easy operation. Attached Figure Description

[0033] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figures 1-9 The first embodiment of the present invention is shown, in which the rope stopper 10 includes: a socket 12 having an inner fitting portion 16 through which the rope 46 (discussed later) passes in one direction; and a plug 14 inserted into and locked into the fitting portion 16, pressing and holding the rope 46 in the socket 12. In the following description, the front-back direction of the protruding portion 18 of the plug 14 is defined as the X-axis direction of mutually orthogonal XYZ axes, which is consistent with the through-path of the rope 46. The left-right direction orthogonal to the X-axis direction is defined as the Y-axis direction, and the surface or thickness direction orthogonal to both the X-axis and Y-axis directions is defined as the Z-axis direction.

[0034] First, the plug 14 will be described. The plug 14 is integrally molded from a synthetic resin such as polypropylene. Figure 9 As shown, the plug 14 is provided with a retaining part 18 that can be inserted into the socket 12.

[0035] The cross-sectional shape of the retaining portion 18 orthogonal to its protruding direction, i.e., the X-axis direction, is rectangular, with the cross-section being longer in the Y-axis direction and shorter in the Z-axis direction, which is the direction of the cover. The contour of the surface of the retaining portion 18 parallel to the X-axis direction is wedge-shaped, and the cross-sectional shape orthogonal to the X-axis direction decreases towards the top end 18a in the protruding direction. On a pair of side surfaces 18b orthogonal to the Y-axis direction of the retaining portion 18, clamping protrusions 20 are provided approximately halfway near the top end 18a. The clamping protrusions 20 are multiple protrusions along the Z-axis direction, protruding in the left-right direction of the Y-axis direction, and the cross-sectional shape of the protruding ends along the XZ plane direction is rectangular.

[0036] A retaining protrusion 22 is provided at the top end 18a of the retaining portion 18. The retaining protrusion 22 is continuously formed with the top end 18a of the retaining portion 18 and a pair of upper surfaces 18d. The cross-sectional shape of the retaining portion 18, which is orthogonal to the Z-axis direction, is a wedge-shaped trapezoid. A portion of the retaining portion 18 protrudes from the upper surface 18d in the Z-axis direction to form the retaining protrusion 22. The amount by which the retaining protrusion 22 protrudes from the upper surface 18d in the Z-axis direction is smaller than the amount by which the guide portion 26, which will be discussed later, protrudes.

[0037] The base end portion 18c, on the side opposite to the top end portion 18a, is continuously formed into a plate shape having side surfaces that are flush with the pair of upper surfaces 18d of the retaining portion 18 and the end faces of the clamping protrusions 20, respectively. The length of the base end portion 18c is shorter than the length of the clamping protrusions 20, and holes 24 of a predetermined depth are formed in the pair of side surfaces of the base end portion 18c orthogonal to the Y-axis direction in order to reduce weight.

[0038] On opposite sides of the base end portion 18c of the retaining portion 18, orthogonal to the Z-axis direction, are erected guide portions 26 protruding in the Z-axis direction. The guide portions 26 are located at the center of the base end portion 18c of the retaining portion 18 and are elongated in the X-axis direction passing through the center of the base end portion 18c. The ends of the base end portion 18c of the retaining portion 18 and the ends of the guide portions 26 opposite to the protruding direction of the retaining portion 18 coincide with each other.

[0039] An operating portion 28 is provided at each of the top ends of a pair of guide portions 26 in the Z-axis direction. The operating portion 28 is a plate having a surface parallel to the XY plane, and is rectangular in shape such that its width in the Y-axis direction is longer than the width in the Y-axis direction of the base end portion 18c of the retaining portion 18, and its width in the X-axis direction is longer than the base end portion 18c. The thickness of each operating portion 28 in the Z-axis direction is thinner than the thickness of the retaining portion 18 in the Z-axis direction. The end of the operating portion 28 opposite to the protruding direction of the retaining portion 18 coincides with the end of the base end portion 18c of the retaining portion 18 and the end of the guide portion 26, and an operating finger hook portion 30 is formed at this end as a protrusion extending from the surface in the Z-axis direction. The operating finger hook portion 30 is formed along the end of the operating portion 28. Furthermore, when the socket 12 and the plug 14 are assembled, the operating finger hook portion 30 is located on the side opposite to the through opening 38 of the socket 12, which will be discussed later. Therefore, guide portions 26 and operating portions 28 of the same shape are provided on both sides of the holding portion 18 in the Z-axis direction, and the pair of operating portions 28 overlap with the clamping protrusions 20 of the holding portion 18 in the Z-axis direction. That is, the plug 14 is formed to be shorter than the sum of the lengths of the holding portion 18 and the operating portions 28 in the X-axis direction. Furthermore, the plug 14 is symmetrical about the central axis in the X-axis direction.

[0040] Next, the socket 12 will be described. The socket 12 is formed integrally from a synthetic resin such as polypropylene. Figure 8 As shown, the socket 12 has a hollow fitting portion 16 for inserting a plug 14. The fitting portion 16 is formed as a cylindrical body, surrounded by a pair of identical surface portions 32 facing each other orthogonal to the Z-axis and spaced apart by a predetermined interval, and a pair of identical side portions 34 located on the side edges of the pair of surface portions 32 and facing each other. Figure 5 As shown, the fitting portion 16 is a space in which the plug 14 fits with a clearance, and there is a gap between the plug 14 and the fitting portion 16 for holding the rope 46, which will be discussed later. Furthermore, the through direction of the rope 46 passing through the fitting portion 16 is the X-axis direction of the plug 14 being inserted into the socket 12.

[0041] One opening of the cylindrical body of the socket 12 is an insertion port 36 for inserting the plug 14 and through which the cord 46 passes. The opposite opening is a through port 38 for pressing the plug 14 to hold the cord 46 and through which the held cord 46 passes. The thickness of the surface portion 32 in the Z-axis direction is approximately constant, while the thickness of the side portion 34 in the Y-axis direction gradually increases from the insertion port 36 side to the through port 38 side. As a result, the spacing between the inner wall surfaces 34a of the side portion 34 gradually narrows from the insertion port 36 to the through port 38. The width of the insertion port 36 in the Y-axis direction is larger than the width of the through port 38 in the Y-axis direction, and the widths of the insertion port 36 and the through port 38 in the Z-axis direction are approximately the same. A plurality of protrusions 40 are provided on the inner wall surfaces 34a of the side portion 34. The protrusions 40 are protrusions provided in the Z-axis direction and are arranged at equal intervals in the X-axis direction. The top of the protrusion is triangular and protrudes toward the insertion port 36.

[0042] Each surface portion 32 is provided with a rectangular sliding groove portion 42. The sliding groove portion 42 is a rectangle that is longer in the X-axis direction, with one end communicating with the insertion port 36, and the other end reaching a position slightly closer to the through port 38 than the middle of the length of the surface portion 32 in the X-axis direction. The portion of each surface portion 32 located between the end of the sliding groove portion 42 and the through port 38 forms a finger placement portion 32a for placing a finger during operation.

[0043] The length of the finger placement portion 32a relative to the socket 12 in the X-axis direction is set at a ratio of 0.3 to 0.5 of the length in the X-axis direction. On the inner wall of each surface portion 32, on the back side of the finger placement portion 32a, a guide recess 44 is provided, formed by cutting away the thickness of the surface portion 32 into a rectangle. The guide recess 44 is a rectangle that is longer in the X-axis direction; one end in the X-axis direction communicates with the through opening 38, and the other end reaches a position slightly separated from the end of the sliding groove portion 42. The sliding groove portion 42 and the guide recess 44 pass through the middle of the width of the surface portion 32 in the Y-axis direction. The ends of the sliding groove portion 42 and the guide recess 44 are set slightly apart from each other, and the portion between the ends of the sliding groove portion 42 and the guide recess 44 forms a stop portion 45 for the plug 14 that moves within the fitting portion 16.

[0044] A finger hook portion 39 protruding in the Z-axis direction is formed on the side edge of the finger placement portion 32a of the surface portion 32 along the through-hole 38. The socket 12 is also symmetrical about the central axis in the X-axis direction.

[0045] Next, the locking operation of the rope stopper 10 according to this embodiment will be described below. First, the rope stopper 10 is installed near the opening of a bag or the like (not shown). A rope 46 passes through the opening along its periphery, and the opening is opened and closed by changing the length by which the two ends 46a of the rope 46 are pulled out from the holes for threading rope.

[0046] In the method of installing the rope stopper 10 onto a package or other installation object, such as Figure 3 , Figure 5 As shown, first, before assembling the plug 14, the two ends 46a of the rope 46 (such as a bag, not shown) pulled out through the hole for threading the rope are inserted into the fitting part 16 through the through-hole 38 in the socket 12 and pulled outward from the insertion hole 36. With the two ends 46a of the pair of ropes 46 respectively close to the two ends in the Y-axis direction of the insertion hole 36, the plug 14 is inserted between the pair of ropes 46 at the center of the insertion hole 36, starting with the top end 18a of the retaining part 18 of the plug 14.

[0047] The retaining portion 18 of the plug 14 is inserted into the inner side of the fitting portion 16 of the socket 12, and the guide portion 26 of the plug 14 is inserted along the sliding groove portion 42. The operating portion 28 moves to the outside of the surface portion 32 of the socket 12. Then, the retaining protrusion 22 abuts against the stop portion 45, which is the end of the sliding groove portion 42, and cannot be inserted further. However, by pressing in with further force, the surface portion 32 is elastically deformed, and the space in the Z-axis direction between the pair of stop portions 45 is expanded, allowing the retaining protrusion 22 to pass through and be inserted into the guide recess 44. The space in the Z-axis direction between the pair of guide recesses 44 is the size that can accommodate the retaining protrusion 22. If the retaining protrusion 22 is inserted into the guide recess 44, the elastic deformation of the surface portion 32 is restored. The retaining protrusion 22 is locked against the stop portion 45 in the pulling direction, and the plug 14 cannot be pulled out relative to the socket 12.

[0048] Thus, the assembly of the socket 12 and the plug 14 is completed, and the installation of the cord stopper 10 into the opening of the bag, etc., is completed. With the cord 46 passing through the socket 12 and the plug 14 assembled with the socket 12, at least a portion of the projection shape of the guide recess 44 on the inner side of the surface portion 32 in the Z-axis direction, which is the thickness direction of the surface portion 32, overlaps with the retaining portion 18 of the plug 14. The loop portion of the cord 46 along the opening extends from the through-hole 38 of the cord stopper 10, and the two end portions 46a of the cord 46 extend from the insertion port 36. The operating portion 28 of the plug 14 is located parallel to the surface portion 32 on the outer side of the surface portion 32 of the socket 12, and the projection shape of the operating portion 28 onto the surface portion 32 is located inside the outline of the surface portion 32. Furthermore, the portion of the finger placement portion 32a of the surface portion 32 of the socket 12 near the through-hole 38 is exposed from the operating portion 28 of the plug 14.

[0049] The retaining protrusion 22 of the plug 14 engages with the guide recess 44 of the socket 12, allowing it to slide between the stop 45 and the through opening 38 in the length direction of the guide recess 44, i.e., in the X-axis direction toward the through opening 38. Even if the plug 14 is moved to any slidable position, the finger placement portion 32a of the socket 12 is exposed relative to the length of the socket 12 in the X-axis direction at a ratio of 0.2 to 0.4 of the length in the X-axis direction.

[0050] If the plug 14 is moved toward the through-hole 38 of the socket 12, the clamping protrusion 20 of the plug 14 approaches the concave-convex portion 40 of the socket 12, and the rope 46 is held and fixed by the clamping protrusion 20 and the concave-convex portion 40. Figures 3-6 As shown, if the plug 14 is moved away from the through-hole 38, the gap between the clamping protrusion 20 and the concave-convex portion 40 widens, and the rope 46 can slide. Even if the plug 14 is moved away from the through-hole 38, the retaining protrusion 22 of the plug 14 is locked in place by the stop portion 45 of the socket 12 and will not fall off, and the operating portion 28 will not extend beyond the end of the socket 12 on the insertion port 36 side.

[0051] Next, the method of using the rope stopper 10 will be explained. When the opening of a bag or similar object to which the rope 46 is attached is closed, while holding the finger placement portions 32a of the pair of surfaces 32 of the socket 12, the other hand pulls the two ends 46a of the rope 46 extending from the insertion port 36 outwards. Pulled by the rope 46, the plug 14 moves away from the through-hole 38 of the socket 12, the rope 46 slides outwards from the insertion port 36, the rope 46 on the through-hole 38 side shortens, and the opening closes. If the opening closes to the desired state, the pulling of the rope 46 stops in that state. In this state, even if the tension that would enlarge the opening is applied to the rope 46, the plug 14 is pulled into the through opening 38 by the clamping protrusion 20 of the plug 14 together with the rope 46. The rope 46 is clamped and fixed by the clamping protrusion 20 of the plug 14 and the concave and convex portions 40 of the socket 12, and the rope 46 will not be pulled out to the opening side to enlarge the opening.

[0052] When opening the opening, similarly, with one hand, hold the operating part 28 of the plug 14 located on the pair of surface parts 32 of the socket 12 and pull it away from the bag, etc. As a result, the operating part 28 of the plug 14 moves away from the through opening 38 of the socket 12 relative to the surface part 32 of the socket 12, and the distance between the clamping protrusion 20 of the plug 14 and the concave and convex parts 40 of the socket 12 increases. Therefore, the rope 46 can slide, and the rope 46 is pulled out from the through opening 38 and becomes longer, and the opening becomes larger, allowing items to be put in and out of the bag, etc.

[0053] The cord stopper 10 according to this embodiment has a small and simple shape, making it easy to use with simple operation. It allows for opening and closing of the opening of a bag or similar item by holding the finger placement portion 32a of the socket 12 together with the operating portion 28 of the plug 14, eliminating the need to switch positions during opening and closing, or to hold the socket 12 and plug 14 separately. This allows for intuitive and easy operation. The socket 12 and plug 14 are symmetrically shaped about the central axis in the X-axis direction, eliminating the need to consider the back or left / right orientation during operation. A socket finger hook 39 is provided in the socket 12, and an operating finger hook 30 is provided in the plug 14, preventing the finger from slipping during opening and closing operations.

[0054] The operating part 28 of the plug 14 is located inside the outline of the surface part 32 of the socket 12, making it compact and preventing damage due to protrusion. Furthermore, if the operating part 28 of the plug 14 protrudes towards the insertion port 36 of the socket 12, the plug 14 might be accidentally pressed into the socket 12 and the rope 46 might become stuck when closing the opening of a bag, etc. However, since the operating part 28 of the plug 14 of the rope stopper 10 does not protrude from the socket 12, the rope 46 will not be accidentally stuck, ensuring good operability. Additionally, the plug 14 is provided with an operating finger hook 30, which allows the plug 14 to be pressed into the insertion port 36 of the socket 12 to lock the rope 46. Even when performing the same operation as existing rope stoppers using metal springs, the rope 46 can be locked without any awkwardness. Even if the finger placement part 32a of the socket 12 is not held, but rather the side part 34, the operation of closing the opening of a bag, etc., can still be performed.

[0055] The base end 18c of the retaining portion 18 of the plug 14 is located between a pair of operating portions 28. Although the retaining portion 18 protrudes sufficiently, the length protruding from the operating portions 28 can be shortened, allowing the plug 14 to be miniaturized into a compact shape. With the miniaturization of the plug 14, the socket 12 can also be miniaturized, enabling a small rope stopper 10. No elastomer is used, resulting in a simple structure and eliminating the need for space to house an elastomer. The number of components is limited to the socket 12 and the plug 14, making it relatively simple. The sliding groove 42 of the socket 12 is covered by the operating portion 28 of the plug 14, preventing foreign objects such as sand and dust from entering.

[0056] Next, based on Figures 10-14The second embodiment of the present invention will be described. Furthermore, components identical to those in the above embodiments will be labeled with the same reference numerals and will not be described in detail. The rope stopper 50 of this embodiment includes: a socket 52 having an inner fitting portion 16 through which a rope 46 passes in one direction; and a plug 14 inserted into and locked into the fitting portion 16, pressing and holding the rope 46 in the socket 52. The plug 14 has the same shape as in the above embodiment and is integrally molded from a synthetic resin such as polypropylene.

[0057] Next, the socket 52 will be described. The socket 52 is integrally formed from a synthetic resin such as polypropylene. The socket 52 has a hollow fitting portion 16 for inserting a plug 14. The fitting portion 16 is surrounded by a pair of surface portions 32 facing each other at a predetermined interval and a pair of side portions 34 located in the Y-axis direction of the pair of surface portions 32 and facing each other, forming a cylindrical body. Figure 12 As shown, the fitting part 16 is a space in which the plug 14 fits with a clearance, and there is a gap between the plug 14 and the fitting part 16 for clamping the rope 46.

[0058] One opening of the cylindrical body of the socket 52 is an insertion port 36 for inserting the plug 14 and through which the rope 46 passes, while the opposite opening is a through port 38 for holding the rope 46 by pressing the plug 14 and through which the held rope 46 passes. The thickness of the surface portion 32 in the Z-axis direction is approximately constant, while the thickness of the side portion 34 in the Y-axis direction gradually increases from the insertion port 36 side to the through port 38 side. The spacing between the inner wall surfaces 34a of the side portion 34 gradually narrows from the insertion port 36 to the through port 38. The width of the insertion port 36 in the Y-axis direction is larger than the width of the through port 38 in the Y-axis direction. Furthermore, the inner wall surface 34a of the side portion 34 does not have a recessed portion 40 such as the socket 12 of the rope stopper 10 of the first embodiment.

[0059] A strap mounting portion 54 is provided on the surface portion 32 forming the insertion port 36. The strap mounting portion 54 is in the shape of a Japanese character "コ" (ko), protruding from the surface portion 32 in the Z-axis direction. The straight portions 54a at both ends of the Japanese character "コ" are flush with the side portions 34 and stand at right angles to the surface portion 32 in the Z-axis direction. The straight portion 54b in the center is positioned parallel to the surface portion 32. The surface portion 32 does not extend into the inner space 54c of the Japanese character "コ" shape, but the inner space 54c of the Japanese character "コ" shape is continuous with the through opening 38. Therefore, the through opening 38 and the inner space 54c are provided to increase the width in the Z-axis direction.

[0060] Each surface portion 32 has a guide recess 44 formed by cutting off the thickness of the surface portion 32 into a rectangle on its inner wall surface. In the surface portion 32 with the mounting portion 54, the guide recess 44 communicates with the inner space 54c that is continuous with the through opening 38. Additionally, as... Figure 14 As shown, in the socket 52, the surface portion 32 does not extend to the mounting portion 54. Therefore, there is no need for a mold portion for the surface portion 32 that forms the inner space 54c. It can be integrally formed using a mold 58 with a simple shape.

[0061] The method for installing the rope stopper 50 onto a bag or similar object is as follows: First, before assembling the plug 14, the strap member 56 is wound around the straight portion 54b of the strap mounting portion 54 of the socket 52, and the end of the strap member 56 is fixed near the rope hole or similar opening of the bag or similar object. Then, similarly to the rope stopper 10, the two ends 46a of the rope 46 pulled out from the rope hole or similar object are inserted into the fitting portion 16 through the through-hole 38 in the socket 52 and pulled outward from the insertion hole 36.

[0062] Next, at the center of the insertion port 36, the plug 14 is inserted between a pair of ropes 46, starting with the tip 18a of the retaining portion 18. The plug 14 is guided into the socket 52 by the sliding groove 42, and the retaining protrusion 22 is inserted into the guide recess 44 via the stop 45, preventing the plug 14 from being pulled out relative to the socket 52. Thus, the assembly of the socket 52 and the plug 14 is completed, and the rope stopper 50 is installed into the opening of the bag, etc.

[0063] The rope stopper 50 is used in the same way as in the embodiment described above. When opening the opening, by holding the operating part 28 of the plug 14 together with a pair of surface parts 32 of the socket 12 with one hand, the weight of the bag or the like is used to pull the rope 46 out of the through-hole 38 of the socket 52. The rope 46 slides and becomes longer, which can enlarge the opening.

[0064] The rope stopper 50 in this embodiment has the same effect as the embodiment described above. When opening the opening, the rope 46 is pulled out of the through-hole 38 of the socket 52 by holding the operating part 28 of the plug 14 together with the pair of surface parts 32 of the socket 12 with one hand, using the weight of a bag or the like. The rope 46 slides and lengthens, thus widening the opening, which is simpler. The inner space 54c of the belt mounting part 54 and the through-hole 38 are formed into a continuous shape excluding the surface parts 32. Therefore, the insertion opening of the belt member 56 is wider, and the belt member 56 is easier to insert. Furthermore, the shape of the mold 58 for integrally forming the belt mounting part 54 can be simplified. Additionally, the rope 46 is also easier to insert.

[0065] Furthermore, the rope stopper of the present invention is not limited to the above-described embodiments; the shape of each component can be freely changed, and the material can be appropriately selected. The item on which the rope stopper is installed can also be any bag, clothing, winter gear, etc.
