Description

Adjustable Bicycle Auxiliary Handlebar < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bicycle auxiliary handle device with height adjustable, and more particularly, to a bicycle auxiliary handle device capable of being attached to and detached from a bicycle handle,

Typical bicycles are equipped with a pair of handles that can be held by both hands so that the driver can maintain balance and steer while operating and a handle bar connecting the pair of handles.

The handle bar is connected to the front wheel fork and a stem for fixing the front wheel shaft. The handle bar can be rotated clockwise or counterclockwise from the driver's point of view with the stem as an axis. .

Thus, the handlebar can rotate clockwise or counterclockwise, but the height of the handlebar is not adjusted.

Since the height is not adjusted, the driver maintains only one posture when operating for a long time, so that the pressure of the muscles caused by the driver's foot cloud is applied to the same points of the spine such as the back and neck for a long time, In many cases, the disease is caused.

In order to solve these problems, various kinds of auxiliary handles for changing the posture of a bicycle driver have been developed and used. The conventional handle bar includes a bar-end type in which a bicycle handle bar is directly engaged with a main handle bar and is projected at both ends in a direction perpendicular to the main handle bar, An airfoil which reduces the air resistance of the driver by bending the waist close to 90 degrees and a direction parallel to the main handle bar at a position higher than the main handle bar, And a butterfly type which can be opened with a screw.

The auxiliary handles are commonly positioned differently from the main handle bar, thereby changing the posture when the driver grasps the auxiliary handles, thereby changing the position of the waist and neck.

However, since the auxiliary handles are fixed to the main handle bar by a coupling means such as a screw, a bolt, or a nut, the coupling position can not be changed during operation. To change the coupling position, the operation is stopped to release the coupling means and then recombine.

Therefore, the existing auxiliary steering wheel provides only one fixed position, so that the driver can not make various posture changes according to the needs, and there is a limit in preventing the spinal disease such as back pain and disc of the driver.

Accordingly, it is a primary object of the present invention to provide a driver with an auxiliary handle in addition to the handle of a bicycle, and the height of the auxiliary handle can be variously adjusted to suit the driver's need during operation, .

In order to achieve the above object, a bicycle auxiliary handle device according to the present invention includes a handlebar (10) having a handle (11) at both ends thereof; At least one support base (20) coupled to the auxiliary handlebar and supporting the auxiliary handlebar; A joint part (30) for folding the support frame so that the support frame is folded at the opposite end of the support frame opposite the engagement part of the auxiliary handlebar; And a coupling part 50 coupled to the joint part and detachable along the outer curved surface of the bicycle handle bar so as to be detachably attached to the handlebar 1 of the bicycle and fastened by a coupling means such as a bolt and a nut, (40) which is coupled with the support and has a restoring force to be brought into close contact with a point of the joint, so that the fixture fixes the support to a predetermined angle with the joint by the restoring force of the fixture .

As described above, the height of the bicycle auxiliary handle device of the present invention is detachably attached to the bicycle handle bar. The bicycle auxiliary handle device is provided with an auxiliary handlebar having a handle at each end, So that the height of the auxiliary handlebar coupled to the support can be easily adjusted not only when the bicycle driver is stationary but also while the bicycle operator is in operation, In addition, since the support is fixed to the joint at a desired angle by a fixture, the driver can take various driving postures according to needs.

Fig. 2 is a cross-sectional view of the bicycle auxiliary handle device of the present invention,
3 is a side view of a bicycle auxiliary handle device of which height is adjustable according to the present invention

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

As shown in Figs. 1 to 2 and Fig. 3, the height of the bicycle auxiliary handle device of the present invention is controlled by the auxiliary handlebar 10 having the handle 11 at both ends thereof, And a support base 20 coupled to the bar 10 for supporting the auxiliary handle bar 10.

The support base 20 is folded so that the support base 20 is folded at the end opposite to the coupling end of the support base 20 with the auxiliary handle bar 10 and the joint base 20 having a plurality of concave- 30 are provided.

A coupling portion 50 which is concaved and recessed along the outer curved surface of the handlebar 1 of the bicycle and can be fastened with a part such as a bolt and a nut is engaged with the joint portion 30, Is detachably attached to the bicycle handlebar (1).

In addition, an elastic body (not shown) coupled to the support 20 in a lever-like shape by a fixture supporter 41 so that the supporter 20 folded on the joint 30 is fixed without being folded at a certain angle And a fastener (40) which is coupled to the one of the plurality of grooves (31) of the joint part (30) by the restoring force of the elastic body (42).

Hereinafter, the operation of the present invention will be described.

First, when the auxiliary handle device of the present invention is attached to the bicycle handlebar 1 by the fastening portion 50, when the angle of folding the support leg 20 with the joint portion 30 is adjusted, The height of the auxiliary handle bar 10 from the ground is adjusted.

When the end of the fastener 40 coupled to the support 20 is brought into close contact with one of the plurality of grooves 31 of the joint part 30, the restoring force of the elastic body 42 coupled to the fastener 40 The support 40 is fixed to the joint 30 so that the support 20 is fixed to the joint 30 and the height of the auxiliary handle bar 10 coupled to the support 20 Is fixed to a specific height selected by the driver.
