Description

TECHNICAL FIELD The present invention relates to a stationary bicycle-type health device that exercises by rotating a flywheel by applying a load to a pedal, and particularly, to supporting a braking belt that controls the rotation of the flywheel. It relates to the device.

2. Description of the Related Art Conventionally, as a method of attaching a braking belt of this type, as shown in FIG. 5, a method of fixing the belt 17 with a buckle 34 attached to a metal fitting 33 has been generally used. That is, one end is hung on the spring 19, the outer periphery of the flywheel 9 is rotated, and the other end is pressed and fixed by the buckle 34. The buckle 34 is screwed to the metal fitting 33 welded to the head pipe 4. Further, the fitting 33 is provided with a groove for fitting the receiving fitting 31 of the outer wire 21. FIG. 6 shows a perspective view of when the belt is removed. In the conventional case, the end portion of the belt 17 is located near the outer wire 21, and it is difficult to adjust the tension, and the structure of the buckle 34 is complicated, and the metal fittings are used. Since it had to be screwed to 33, the unit price was high and the number of man-hours required was high. In addition, the outer wire receiving metal fitting 31 often slips off in the lateral direction when vibration is applied when the wire is loose, which is not a preferable method.

Problems to be Solved by the Invention As described above, the conventional configuration has the following problems.

(1) The belt end is near the outer wire, making it difficult to attach and detach the belt and adjust the length.

(2) The structure of the buckle that prevents the belt from loosening becomes complicated,
The unit price increases.

(3) The buckle must be fixed to the metal fitting, which requires a lot of screwing work, which increases the manufacturing cost.

(4) When the outer wire tends to loosen, the bracket may sometimes come off laterally.

Means for Solving Problems The method of screwing the press-fixing buckle to the metal fitting is not preferable also in terms of external design, and the present invention solves the problems of the above-mentioned conventional example. This belt support fitting is provided with a belt hooking groove and a hole for fitting the outer wire to the fitting fitting so that the fitting fitting does not come off. The braking belt itself is, for example, folded at its end and crossed with a suitable stopper to prevent it from loosening.

At the time of assembly, lift the bracket fitted with the outer wire,
First, the inner wire is guided to the predetermined hole position for fitting through the belt hooking groove of the belt support fitting and the groove having the width through which the inner wire passes, and then fitted. A loop whose belt end is folded back by a stopper is used, and then the belt is hung on the supporting metal fitting using the hooking groove. Therefore, the outer wire does not come off due to the groove of the width through which the inner wire passes,
Further, the belt can be easily removed by simply shifting it laterally, and has a simple structure, good workability, and cost reduction.
