And the gripping member 23, the base frame 13 is engaged by engaging the inner circumferential surface of the rotating frame 22 in the rotating unit 20 with the outer circumferential surface of the base frame 13 formed in a circular cross section. The grip unit assembly 21 is rotatable relative to the center of rotation.

This is the same as the principle of inserting and rotating the sliding bearing in the shaft end.

Since there is a torsion spring 24, one side of the torsion spring 24 is fixed to the fixing unit 10 and the other side is fixed to the rotating unit 20.

That is, the first arm portion 24a having one side of the torsion spring 24 in a bar shape is inserted into and fixed in the spring fixing groove 13e in the base frame 13 of the fixing unit 10, and the other The second arm portion 24b on one side has an annular shape, and a spring fixing screw groove 22d is formed in the spring fixing boss 22c in the rotating frame 22 of the holding part assembly 21 of the rotating unit 20. It is provided and fixed with a spring fixing screw (28).

Here, the virtual torsion spring axis center 24s of the torsion spring 24 coincides with the base frame axis center 13s of the base frame 13 and the rotation frame axis center 22s of the rotation frame 22 so that The gripper assembly 21 has a structure of repeating rotation and returning due to the tension of the torsion spring 24 using the base frame 13 as the center of rotation as the fixed unit 10.

Here, in one embodiment of the bicycle handle (02) with a shock absorbing function of the present invention has been described by designating the function of the shock absorbing and home return to the torsion spring 24, the shock absorbing and returning function described above as a spring member It is also possible to use other similarly possible spring members, such as leaf springs, spring springs, and the like.

In FIG. 16, the rotating unit 20 shows a no-load state in which no external force F is applied.

In the figure, the first arm portion 24a of the torsion spring 24 is fixed in parallel with the vertical line and the second arm portion 24b is kept in parallel with the horizontal line.

That is, the torsion spring 24 maintains 90 degrees of the 1st arm part 24a and the 2nd arm part 24b in a no-load state.

Then, when the rotation unit 20 rotates around the base frame 13 of the fixed unit 10 as the center of rotation according to the action of the external force F, the torsion spring 24 coupled to the fixed unit 10. Of the first arm portion 24a of the torsion spring 24 coupled to the rotation unit 20 is a torsion spring (within the rotation range along the rotation unit 20). It rotates in the winding direction or the winding direction of 24).

Here, in one embodiment of the present invention will be described by specifying the winding direction of the torsion spring 24 in the counterclockwise direction.

At this time, the rotation range is preferably within 30 degrees in the counterclockwise direction, within 10 degrees in the clockwise direction.

Of course, the limitation of the angle with respect to the rotation range is not limited to the presented angle.

Accordingly, the limit angle of the rotational movement limiting range (v) with respect to the winding direction (counterclockwise direction) of the torsion spring 24 on one side of the base frame 13 of the fixing unit 10 which becomes the rotation center axis. The second stop wall 13f is provided at the position corresponding to the limit angle of the rotational movement limit range w with respect to the winding reverse direction (clockwise) of the first stop wall 13d and the torsion spring 24 at the position.

When a force F1 is applied in the winding direction of the spring 24, the rotation unit 20 generates a rotation torque T1 to rotate counterclockwise and springs in the rotation frame 22 of the rotation unit 20. The second arm portion 24b of the torsion spring 24 fixed to the fixed boss 22c also rotates with the same trajectory as the rotation angle of the rotation unit 20.

This means that the load is acting in the winding direction of the torsion spring 24.

The rotating unit 20 in which the rotating action is started is formed when the first diaphragm 22a installed in the rotating frame 22 reaches the first stop wall 13d provided on one side of the base frame 13 of the fixing unit 10. After that, no further rotation will proceed.

Thereafter, when the force F1 is removed in the winding direction applied to the support region 23a in the holding unit assembly 21 of the rotary unit 10, the load acting in the winding direction of the torsion spring 24 is also removed. The rotating unit 20 is returned to its original state by the restoring force of the torsion spring 24.

Referring to FIG. 18 in conjunction with FIG. 16,

The rotation state of the rotating unit 20 is shown when the force F2 acts in the winding reverse direction (clockwise) of the torsion spring 24.

As shown in the figure, when the end bar 29, which will be described later, is replaced by replacing the end cover 27, which is a component of the rotating unit 20, the bicycle occupant touches the holding member 23 of the rotating unit 20. When the grip posture of holding the end bar 29 is taken without taking the general grip posture of holding the vehicle, the body load of the occupant is set to the base frame central axis 13s of the base frame 13 of the fixed unit 10. When viewed from the central axis of rotation generates a force (F2) in the winding direction (clockwise) of the torsion spring 24, which is the rotary unit 20 is rotated in response to the clockwise torque (T2) It is present.

At this time, as described above, the first arm portion 24a of the torsion spring 24 is inserted into and fixed to the spring fixing groove 13e in the base frame 13 of the fixing unit 10, and the second arm portion ( 24b is fixed to the spring fixing boss 22c in the rotating frame of the holding part assembly 21 of the rotating unit 20, so that the second arm portion 24b of the torsion spring 24 is also the rotating unit 20. ) Rotates with the same direction and trajectory of rotation.

Here, the torsion spring 24 has a load acting in the reverse direction, and the rotating unit 20 in which the clockwise rotation is started is fixed to the second diaphragm 22b installed in the rotating frame 22 of the rotating unit 20. After reaching the second stop wall 13f provided on one side of the base frame 13 of the unit 10, the rotation does not proceed any further.

Then, when the force F2 is removed in the winding reverse direction applied to the end bar 29 of the rotary unit 10, the load acting in the winding reverse direction of the torsion spring 24 is also removed to remove the torsion spring 24. The rotation unit 20 is returned to its original state by the restoring force.

In another embodiment of the present invention shown in Figs. 19 and 20, the end bar 29 is fastened in place of the end cover 27, which is a part of the rotation unit 20 in the configuration shown in Fig. 8.

This has the form of mounting a separate auxiliary handle on the handle of the normal bicycle handlebars.
