本考案は紐材端部に筒部材を取付ける装置、例
えば縄跳びに用いる運動遊戯器の紐材両端部にグ
リツプとしての筒部材を取付ける装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a cylindrical member to the end of a string material, such as a device for attaching cylindrical members as grips to both ends of a string material of an exercise machine used for jumping rope.
この縄跳び用運動遊戯器の従来例を第１図に基

金具であつて紐材端部５にカシメ固着される。 A conventional example of this exercise equipment for jumping rope will be explained based on FIG. End 5 inserted from mouth 3
A stopper 6 is fixed to the cylindrical member 1, so that the end 4 of the string material is attached to the connecting port 3 of the cylindrical member 1 in a manner that prevents it from coming off. The stopper 6 is a metal fitting having a larger diameter than the connecting port 3, and is fixed to the end portion 5 of the string material by caulking.

ら、輸送保管にも不便である。 However, in this conventional example, since the pull-out stopper 6 is merely caulked and fixed, the pull-out stopper 6 is easily separated from the string end 5 after being used for a long period of time due to repeated rope jumping. This may lead to an unusable condition. Further, since the portion of the string material 4 near the connecting port 3 is not protected at all, there is a risk that the end portion 5 of the string material may be severed due to severe bending and twisting by the rope jumper. Furthermore, since the product is shipped with the stopper 6 fixed in advance to the end 5 of the string material, it is inconvenient for transportation and storage.

ある。 In view of the above, the present invention has been developed to prevent the removal stopper from separating from the end of the string even after repeated use over a long period of time, and to suitably protect the end of the string from being cut even under severe usage conditions. Furthermore, it is an object of the present invention to provide a device that allows the string material and the cylindrical member to be separated for transportation and storage by making it possible to easily attach and detach the stopper to the end of the string material by hand without requiring a caulking metal fitting or the like. It is.

止する。 One embodiment of the present invention will be described below in detail based on the drawings. Figures 2 to 4 show a jump rope exercise machine as a device for attaching a cylindrical member to the end of a string material according to the present invention. , cylindrical member 11 as a grip
is integrally molded of plastic into a generally cylindrical shape, has an internal hollow portion 12, and is open at both ends. One end opening is a connecting port 13 having a smaller diameter than the hollow portion 12 . The string material 14 is extruded into a tube shape from relatively soft plastic, and a stopper 16 is fixed to the end 15 inserted through the connection port 13 of the cylindrical member 11. This pull-out stopper 16 includes a series of small-diameter portions 17 and large-diameter portions 18 formed by winding a single strip of steel wire into a coil, and connects the different-diameter stepped portions of the small-diameter portions 17 and 18 to a tapered portion. 19. The small diameter portion 17 is smaller in diameter than the connecting port 13 of the cylindrical member 11 and holds the wire 14 therethrough, and the winding pitch of the steel wire is tightly arranged at both ends of the small diameter portion 17. The steel wire is provided with a rough portion 21 in which the winding pitch of the steel wire is roughened in the intermediate portion. The large diameter portion 18 has a larger diameter than the connecting port 13, is located within the hollow portion 12, and holds the string end 15 inserted through the small diameter portion 17 in a folded state in the axial direction. . The large-diameter portion 18 is provided with a series of locking portions 22 extending in an arc shape across the coil end of the steel wire in the diametrical direction as shown in the fourth figure at the open end, and the end of the locking portion 22 is formed into a locking end 23 that comes into contact with the opening edge of the large diameter portion 28, and this locking portion 22 locks on the inner peripheral portion of the folded portion 24 of the string material end portion 15.

７より抜出せば良い。 To attach the string end 15 to the cylindrical member 11 based on this embodiment, the string 14 is inserted through the connecting port 13 at one end of the cylindrical member 11 and then inserted through the opening at the other end. Next, the end portion 15 of the string material is inserted through the small diameter portion 17 of the stopper 16 and inserted through the large diameter portion 18, and the inserted end is folded back in the axial direction so as to hold the locking portion 22, and the diameter is tightened again. Insert into the main portion 18 from the opposite direction. On this occasion,
The work is easy if the tip of the string end 15 is cut obliquely to form a sharp part 25 as shown in the third figure. In this state, the tube-shaped string material 14 is contractible and has a restoring elastic force, and the folded end portion 15 of the string material is held in close contact with the inner surface of the large diameter portion 18. Therefore, the string material 14
When pulled against the cylindrical member 11, the small diameter portion 17 of the stopper 16 is inserted from the connecting port 13, the tapered portion 19 abuts and locks on the edge of the connecting port 13, and the string material 14 is inserted into the cylindrical member. It is attached to the member 11 in a manner that prevents it from coming off. In this state, the folded part 24 of the string material end 15 has a large diameter part 18.
The locking portion 22 connects the locking end 23 to the large diameter portion 18.
Therefore, no matter how much the string material 14 is pulled while the tapered part 19 is in contact with the edge of the connecting port 13, the folded and overlapped end portion 15 of the string material
is in close contact with the inner surface of the large diameter portion 18, and the folded portion 2
The locking part 22 only bites into the inner peripheral part of the cord 14, and the string material 14 will not separate from the stopper 16 even under strong tensile force. In addition, the part of the cord material 14 near the connection port 13 is protected by the small diameter part 17, and the cord material 14 is held firmly by the dense parts 20, 20 in particular, while the coarse part 21 is protected by tension, bending, and compression. It is easily flexible and deformable in any direction, and fatigue of the string material 14 can be suitably prevented. Incidentally, the string material 14 and the cylinder member 11
In order to separate the
6 from the opening at the other end of the cylindrical member 11, pull out the folded part 24 from the large diameter part 18 to release the locking part 22, and insert the cord end 15 into the small diameter part 1 of the stopper 16.
It is better to extract it from 7.

できる簡便性がある。 As a result of the present invention configured as described above, the string material 14
When fixing to the stopper 16, the folded part 24 of the tube-like string end 15 is held by the large diameter part 18, and the locking part 2 is attached to the inner circumference of the folded part 24.
In addition, since the locking end 23 of the locking portion 22 is in contact with the opening edge of the large diameter portion 18, the connection is strong. is more firmly coupled to the folded portion 24 by biting into the locking portion 22, thereby reliably preventing separation of the cord material 14 and the stopper 16. Moreover, the cord material 14 near the connecting port 13 is
The rough portion 21 is firmly held by
The cord material 14 is suitably protected through the cord material 14, and fatigue of the cord material 14 is prevented. In addition, since the pull-out stopper 16 and the string end 15 can be easily attached and detached by hand without the need for caulking, the string member 14, the pull-out stopper 16, and the cylindrical member 11 can be separated for transportation and storage. Moreover, they are so convenient that they can be easily assembled by the user himself.
