Description

[Detailed Description of the Invention] The present invention relates to a cableway reel used for guiding a bent part of a cableway attached to a bicycle frame or the like.

Conventionally, cableways such as bicycle brake wires or dayrailer wires have been attached to the frame from the handle lever etc. to each device, and at each corner of the frame, the cableway itself has been made to have a large bend or a guide groove has been added to guide the wires. Because it is sliding,
There were problems such as an increase in frictional resistance at the bent portions and limitations in the locations where the frame structure and various devices could be used.

The present invention was devised to solve the above-mentioned problems, and aims to provide a reel for a cableway that can reduce the frictional resistance at the bending part of the cableway and also allow the bending angle of the wire to be set arbitrarily. be.

An embodiment of the present invention will be described below based on the drawings. In this embodiment, a reel 3 for guiding an inner wire 2 is rotatably fitted around the outer periphery of a cylindrical collar bushing 1, and an outer receiver 5 for receiving and connecting the end of the outer wire 4 is connected to the tangent of the disc. An inner case 6, which is made of two disks with a center hole 8 and connected together at an appropriate interval, is placed over both sides of the collar bush 1 and reel 3, and the end of the outer wire 4 is An outer case 7 which has an outer receiver 5 for receiving and connecting in the tangential direction of the discs and has two discs with a center hole 8 connected together at an appropriate interval.
are abutted so as to cover both outer sides of the inner case 6, and a shaft 9 such as a bolt is inserted through the center hole 8 of the collar bush 1 and each case 6, 7, and fastened with a nut 10.

In this case, the length of the collar bush 1 is made slightly larger than the thickness of the reel 3, and when the collar bush 1 is fastened with the nut 10, the cases 6 and 7 are crimped and fixed together, but the reel 3 still rotates freely. It can be so.

In the cableway reel of the present invention constructed as described above, the ends of the outer wire 4 are connected to the outer receivers 5 of the inner case 6 and the outer case 7, and the inner wire 2 is connected to the rotatable reel 3.
For example, as shown in Figure 3,
Required positions 12, 13, on the bicycle frame 11
14 respectively. In this way, the movement of the inner wire 2 due to the operation of devices such as brakes and derailleurs is absorbed by the rotation of the reel 3, so that the sliding frictional resistance of the inner wire in the conventional device is almost eliminated. Therefore, according to the present invention, it is possible to significantly reduce the sliding frictional resistance of the inner wire.

Furthermore, the inner case 6 and outer case 7 of the present invention can be freely rotated about the shaft 9 as shown by the arrow in FIG. 1 by loosening the nut 10, so the angle of the bent portion can be set arbitrarily. be able to. Therefore, cableways can be used for equipment and frames for which conventionally it was difficult to arrange due to increased frictional resistance, expanding the scope of use, and the structure is simple. This invention has many practical effects, such as being able to manufacture it at low cost.

Furthermore, in the device of the present invention, even if tension is applied to the inner wire 2, the resultant force does not act at all on the attachment point of the device to the bicycle frame. Therefore, according to the present invention, it is easy to install the device, and the installation position can be freely selected.
