Adjustable grip brake control group

The invention relates to brake control; in particular to a brake control group with adjustable grip.

The angle between the brake handle on the bicycle and the handlebar is generally referred to as the "grip distance." In general, if the brake system that is to be actuated by the line inhibits the rotation of the wheel of the bicycle, the brake handle is initially pressed, and the brake function cannot be started immediately. Instead, the brake pad is clamped to the frame after pressing an empty stroke. The braking purpose is achieved, and the free travel that cannot drive the brake system is hereinafter referred to as "brake air travel".

The existing bicycle brake control group will change the "brake air stroke" at the same time when adjusting the "grip distance", and it needs to be assisted by the hand tool for the rider to adjust. Therefore, after adjusting the "grip distance", the rider It is necessary to get used to the change of "brake air stroke", so the rider may be in danger of being accustomed to the new "brake air stroke" before he is used to it.

When the "brake air stroke" is too long, it is easy to cause the brake timing to follow, and it will hit the vehicle in front. In addition, when the brake is in the process of high speed, and the "brake air stroke" is too short, it is easy. Causes the bicycle to overturn. Therefore, too long or too short "brake air travel" is easy to cause damage to the rider during the ride.

Therefore, the adjustment of the "grip distance" structure of the conventional bicycle has yet to be improved.

In view of the above, it is an object of the present invention to provide a brake control group that can easily change the grip distance without changing the brake idle stroke.

In order to achieve the above objective, the present invention provides a brake control group with adjustable grip distance for being disposed on a handlebar of a bicycle, and the bicycle includes a brake line, and the brake control group of the adjustable grip includes: A fixed seat, an actuating member, a brake handle, and an adjusting member. The fixing seat is fixed to the handle bar. The actuating member is pivotally mounted on the fixing seat and has a consistent hole. The brake handle is pivotally disposed on the fixing base coaxially with the actuating member for coupling to the brake wire, and the brake handle has a screw hole. The adjusting member has a shaft and a stopping portion connecting the shaft, and the shaft has an externally threaded portion; the shaft is disposed on the screw hole and the through hole, and the threaded portion outside the shaft It is coupled with the internal thread of the screw hole, and further, the stopper abuts against the actuating member.

Thereby, the angle between the brake handle and the handlebar is adjusted by rotating the adjusting member to change the distance between the stopping portion and the brake handle.

According to the above structural combination, the grip distance can be easily adjusted, and when the grip of the brake handle is adjusted, the position of the actuating member is not changed, so that the brake idle stroke is not changed when the grip distance is adjusted.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the accompanying drawings. Referring to FIG. 1 to FIG. 5, the brake control of the adjustable grip according to the first embodiment of the present invention is shown. The group 100 includes a fixing base 10, an actuating member 20, a brake handle 30, a shaft 40, an adjusting member 50, a torsion spring 60 and an elastic member 70.

The fixing base 10 has a beam ring 11 , a receiving groove 12 , an abutting surface 13 perpendicular to the bottom surface of the receiving groove 12 , a joint 14 and a joint receiving hole 15 communicating with the receiving groove 12 . The joint 14 is disposed in the joint receiving hole 15. The fixing base 10 is sleeved on a bicycle handlebar 920 through the collar 11 .

The actuating member 20 and the brake handle 30 are disposed in the accommodating groove 12 and are simultaneously disposed on the opposite side walls 12a of the accommodating groove 12, the actuating member 20 and the brake handle 30 by the shaft 40. The actuating member 20 is pivotally disposed on the fixing base 10 coaxially with the brake handle 30. In addition, the surface of the middle portion of the shaft 40 has a embossing pattern 40a, and the shaft is tightly fitted to the actuating member 20 by the embossing 40a without falling off.

The actuating member 20 has a fixing portion 21, a constant hole 22, and a dam 23 protruding from the wall surface of the through hole 22 (as shown in FIG. 4). The fixing portion 21 has a fixing hole 21a. A brake wire 910 of the brake device (not shown) of the bicycle passes through the joint 14 of the fixing base 10, and a cylindrical terminal 911 at the end of the brake wire 910 is disposed in the fixing hole 21a, so that the actuating member The fixing portion 21 of 20 is coupled to the brake wire 910.

The through hole 22 is located above the shaft 40 and perpendicular to the shaft 40. The longitudinal axis length LX of the aperture of the through hole 22 is greater than the horizontal axis length LY (as shown in FIG. 5), so that the shaft 51 can swing in the longitudinal direction of the through hole 22.

The brake handle 30 has a screw hole 31, and the screw hole 31 is located inside the brake handle 30. The adjusting member 50 has a shaft 51 and a stopping portion 52 connecting the end of the shaft 51, and the shaft 51 has an externally threaded portion. The shaft 51 extends through the screw hole 31 and the through hole 22, and the external thread portion of the shaft 51 is screwed into the internal thread of the screw hole 31, so that a part of the shaft 51 is located in the through hole 22. Further, the shaft 51 is swingable in the longitudinal direction of the through hole 22. The length of the stop portion 52 is greater than the length of the aperture of the through hole 22 to abut against the actuator 20. In the embodiment, the shaft 51 is a bolt, the stopping portion 52 is a nut, and the bolt and the nut are connected by screwing. In addition, in other embodiments, the blocking portion 52 can be a buckle or a pin, and is not limited to a nut.

The elastic member 70 is a spring, and one end of the elastic member 70 is abutted against the damper 23, and the other end is abutted against the brake handle 30 (as shown in FIG. 4). The elastic member 70 provides a thrust to the brake handle 30 to push the brake handle 30 to rotate in a direction until the stopping portion 52 abuts against the actuating member 20, and the through hole 22 of the actuating member 20 is The screw holes 31 of the brake handle 30 are maintained at a fixed distance. Therefore, when the brake handle 30 is rotated in one direction, the brake handle 30 pulls the actuating member 20 through the adjusting member 50 to synchronously rotate the actuating member 20 to perform a braking action.

The torsion spring 60 is disposed in the receiving groove 12 and sleeved on the shaft 40. One end of the torsion spring 60 is fixed on the actuating member 20, and the other end abuts against the abutting surface 13. When the brake handle 30 is pressed to drive the actuating member 20 to rotate in one direction, the torsion spring 60 The actuating member 20 exerts a force in the opposite direction, so when the brake handle 30 is stopped, the actuating member 20 and the brake lever 30 are returned to the original position due to the force of the torsion spring 60.

In addition, the brake control group 100 further includes two spacers 80. The shims 80 are respectively located between the brake handle 30 and the opposite side walls 12a of the accommodating groove 12, and are penetrated by the shaft 40. When the brake handle 30 is rotated, the brake handle 30 is not fixed. The seats 10 rub against each other.

Referring to FIG. 6, the angle between the brake handle 30 and the handlebar 920 is conventionally referred to as "grip distance." For riders of different sizes, the pressure applied to the handlebar 920 varies from person to person, and the "grip distance" suitable for the rider's hand is also different. Therefore, when the adjusting member 50 of the embodiment is rotated, because the external thread segment on the shaft 51 cooperates with the internal thread of the screw hole 31, and the elastic member 70 continues to push against the brake handle 30, The stopping portion 52 continues to abut against the actuating member 20, so that the brake lever 30 rotates in one direction to change the angle between the brake handle 30 and the handlebar 920 until the ride is comfortable. The grip distance is up.

For example, when the rider wants to shorten the grip distance, the adjusting member 50 is rotated in a clockwise direction because the elastic member 22 continues to push against the brake handle 30, and the externally threaded portion of the shaft 51 and the screw The engagement of the internal threads of the aperture 31 causes the brake handle 30 to rotate in a clockwise direction to reduce the angle with the handlebar 920. On the other hand, when the rider wants to extend the grip distance, the adjuster 50 is rotated in a counterclockwise direction, and the shaft 51 pulls the stop portion 52 to continuously abut the actuating member 52. The engagement of the externally threaded section on the shaft 51 with the internal thread of the screw hole 31 causes the brake handle 30 to rotate in the counterclockwise direction to increase the angle with the handlebar 920.

Another mention is that when the rider wants to brake and press the brake handle 30, the brake wire 910 will be pulled through the actuating member 20 until the brake pad (not shown) clamps the frame to the brake. The distance moved by the handle 30 is hereinafter referred to as "brake idle stroke", and the longer the brake idle stroke is, the lower the sensitivity at the time of braking. On the contrary, the shorter the brake idle stroke is, the higher the sensitivity at the time of braking, and the sensitivity is too high or too low. It is harmful to the safety of the rider. However, the present invention does not change the position of the actuating member 20 when adjusting the grip distance of the brake handle 30. Therefore, when the grip distance is adjusted, the brake idle travel is not changed to maintain the brake idle travel when the grip is not adjusted. And keep the rider's own habit and safer brake air travel.

As shown in FIG. 7 and FIG. 8, the brake control group 200 of the adjustable grip distance according to the second embodiment of the present invention is shown. The brake control group 200 of the adjustable grip of the second embodiment differs from the brake control group 100 of the adjustable grip of the first embodiment in the screw hole position of the brake handle, thereby causing the brake control group 200 of the second embodiment. The adjustment member 250 is different from the position of the adjustment member 50 of the brake control group 200 of the first embodiment.

The screw hole 231 of the brake lever 230 of the brake control group 200 is close to one end of the brake handle 230 and is in the same direction as the pressing surface of one of the brake handles 230. The pressing surface refers to a surface on which the rider applies pressure to the brake handle 230 when the rider brakes. The adjusting member 250 passes through the screw hole 231 of the brake handle 230 and the through hole 222 of the actuating member 220 to be combined with the stopping portion 252 , and then the actuating member 220 and the brake handle 230 are disposed on the fixing base 210 . The accommodating member 220 is coaxially disposed with the brake handle 230 by the shaft 240 and the opposite side walls of the accommodating groove 212, the actuating member 220 and the brake handle 230. Fixing seat 210. The rider can adjust the grip by rotating the adjustment member 250. Further, since the surface through which the adjusting member 250 penetrates and the pressing surface are in the same direction, the rider can rotate the adjusting member 250 without hindrance.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
