Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a brake lever,
In particular, the present invention relates to a vehicle brake lever connected to the other end of a connection member having one end connected to a brake device of a vehicle such as a bicycle, a tricycle, and a walking aid.

[0002]

2. Description of the Related Art A brake lever of a vehicle such as a bicycle or a tricycle generally includes a brake bracket mounted on a handlebar and a lever body swingably mounted on the brake bracket. The outer casing of the brake cable is locked to the brake bracket, and the inner cable is locked to the lever body. The tip of the brake cable is locked by the brake device, and when the lever body is swung, the inner cable is pulled and the brake device brakes the wheels.

A type of brake lever having a lock mechanism that locks the state in which the lever body is swung, that is, the state in which the brake is applied, is conventionally known (Japanese Utility Model Laid-Open No. 50-71953). 51-116
No. 547). By locking the lever body in this manner, the braking state can be maintained when the bicycle is parked. For example, the front wheel is braked, so that the bicycle can be prevented from moving due to free movement of the front wheel when parking the bicycle on an inclined surface or the like. . It is also convenient for tricycles when parking on slopes.

The lock mechanisms disclosed in the above-mentioned conventional publications are all provided on a brake bracket. More specifically, the lock mechanism described in the former publication includes a U-shaped bracket fixed to the operation side of a brake bracket, a lock shaft movably mounted on the U-shaped bracket, and a lock shaft. And a coil spring biasing to the release side.
The U-shaped bracket is fixed to the pivot shaft of the brake lever. The lock shaft is movable between a position for locking and locking the lever body and a release position for releasing the lock.

In the former conventional locking mechanism, when the lock shaft is pressed down while the lever body is swung during parking or the like, the lock shaft is inserted between the end surfaces of the lever body and the brake bracket. . When the hand is released from the lever body in a state where the lever body is pressed down, the lock shaft is fixed by the return force of the inner cable and the frictional force of the lock shaft, and is locked while the lever body is being pulled. When releasing the lock, if the lever body is slightly pulled, the fixing by friction is released, the lock shaft returns to the original position by the urging force of the coil spring, and the lock is released.

The lock mechanism disclosed in the latter publication includes a lock shaft movably provided on a brake bracket,
A lock piece protruding from the peripheral surface of the lock shaft, a guide groove provided to guide the lock piece to the brake bracket, and a coil spring for urging the lock shaft toward the lock side are provided. A knob for rotating the lock shaft is provided at a rear end of the lock shaft. The lock piece has such a shape that it is gradually inclined toward the front end so as to regulate the swing angle of the lever body.

In the latter conventional lock mechanism, usually, the lock shaft is projected forward, and the lock shaft is slightly rotated so that the lock piece and the guide groove do not face each other to lock the lock shaft to the brake bracket. Keep it. In this state, the swing angle of the lever body is freely regulated without any restriction. When locking with the lever body pulled, the knob is squeezed to swing the lock shaft so that the guide groove faces the lock piece.
Then, the lock shaft is urged by the coil spring to advance and the lock piece restricts the swing angle of the lever body and locks.

[0008]

In each of the above-mentioned conventional lock mechanisms, the lock mechanism is provided on the brake bracket, so that the stroke of the lock shaft becomes large,
The lock shaft protrudes greatly from the bracket surface. In particular,
In the former conventional lock mechanism, since a commercially available brake lever is configured to be used, a U-shaped metal fitting protrudes largely on the operation side (usually the front side), and the lock shaft further protrudes therefrom. For this reason, the lock mechanism including the lock shaft protrudes largely toward the operation side of the brake bracket, which hinders the brake operation and may cause an erroneous operation by being touched by mistake.

In the latter conventional lock mechanism, since the lock shaft always penetrates the brake bracket, the amount of protrusion is smaller than that of the former, but the lock shaft also protrudes largely toward the operation side during normal lock release. Similarly, it may hinder the brake operation and may cause an erroneous operation. Further, when performing the lock operation and the lock release operation, in order to surely perform those operations, the lock shaft must be rotated to adjust or shift the position of the guide groove and the lock piece. For this reason, it is difficult to rotate the lock shaft with the same right hand while pulling the lever body with, for example, the right hand, and it is necessary to perform the lock operation with both hands. Therefore, it is difficult to perform locking and unlocking with one touch.

[0010] An object of the present invention is to provide a brake lever with a lock mechanism which has a small amount of protrusion and does not hinder a brake operation. Another object of the present invention is to provide a brake lever with a lock mechanism, which has a small amount of protrusion and can be locked and unlocked with one touch.

Therefore, locking and unlocking can be reliably performed with one touch.

[Other Embodiments] (a) In the above embodiment, a ring member 62 is provided at the tip of the lock shaft 60, the tip of the lock shaft 60 is locked to the brake bracket 30, and the advanced position is set by the ring member 62. It was configured to hold the lock shaft 60 with
As shown in FIG. 7, the lock shaft 60 may be held by the frictional force and the return force by the inner cable 25a. In this case, the ring member 63 as the retreat position holding body is mounted slightly proximal to the distal end of the lock shaft 60. The ring member 63 is formed of, for example, an E-shaped retaining ring, and is removably mounted in an annular groove formed on the proximal end side or the distal end of the lock shaft 60.

The other configuration is the same as that of the above embodiment, and the description is omitted. In this embodiment, since the lock shaft is not held at the advanced position by the ring member 63, the bending portion 41a is not provided in the bracket main body 41 of the brake bracket 30. In such a configuration, when the lever body 31 of the brake lever 16 is gripped and swung, the inner cable 25a is pulled, and the brake shoe, for example, of the brake device 8 contacts the rim of the front wheel 6 and is braked. In this state, when the lock shaft 60 is pushed forward with, for example, the index finger of the hand holding the lever body 31, the lock shaft 60 is fixed to the base end side from the distal end of the lock shaft 60 as shown by a two-dot chain line in FIG. The ring member 63 contacts the inner surface of the bracket body 41 on the operation side, and the tip of the lock shaft 60 slightly protrudes from the outer surface of the bracket body 41 on the operation side. When the hand is released from the lever body 31 in a state where the lock shaft 60 is pressed, the lock shaft 60 comes into contact with the bracket body 41 at the lock position and is locked, and the return force of the inner cable 25 a and the frictional force of the lock shaft 60 cause the lock shaft 60 to return. The lever body 31 is locked at a predetermined swing position. At this time, if the brake device 8 and the brake cable 25 are adjusted so that the brake shoe is pressed against the rim, the brake is applied in this state, and the function of the parking brake is realized.

In this locked state, when the lever body 31 is slightly swung to a position closer to the handlebar 15 than a predetermined swinging position, the frictional force between the lock shaft 60 and the brake bracket 30 disappears, and the coil spring 61 The lock shaft 60 is retracted by the urging force. At this time, the ring member 6
3 is larger than the mounting hole 58, the lock shaft 60 is moved by the ring member 63 hooked on the lever body 31 as shown in FIG.
Is held at a retreat position (lock release position) indicated by a solid line. As a result, the lock of the lock shaft 60 is released, and the locked state of the lever body 31 by the lock mechanism 32 is released.
Here, the locked state is released only by swinging the lever body 31.

With such a configuration, the same effect as described above can be obtained. Further, when releasing the lock, the brake bracket 30 is not hooked on the ring member 63 to hold the lock shaft 60. Therefore, the lock can be easily released only by slightly swinging the lever body 31. This further simplifies the brake release operation. (B) In the above embodiment, the ring member is provided separately from the lock shaft, but the ring member and the lock shaft are integrally formed,
The head may be detachably provided on the lock shaft.

(C) In the above embodiment, a bicycle was described as an example. However, the present invention can be applied to brake levers for all vehicles such as tricycles, walking aids, and shopping carts. (D) In the above embodiment, the present invention is applied to the brake lever on the front wheel side, but may be applied to the brake lever for the rear wheel. (E) In the above embodiment, the advance position holding member and the retreat position holding member are also used. However, as shown in FIG. 8, both holding members may be provided separately. In FIG. 8, the ring member 62 provided at the distal end is the advance position holding body, and the ring member 63 formed of a retaining ring similar to the other embodiment shown in FIG. 7 is the retreat position holding body. In such a configuration, since the retraction position is not held by the ring member 62 which is the advance position holding body, the stroke of the lock shaft 60 can be shortened,
The amount of protrusion on the side opposite to the operation side can be further reduced.

[0038]

According to the present invention, since the lock mechanism is provided on the lever body, the amount of protrusion of the lock mechanism can be reduced. The lever can be locked by a simple operation of extending the lock shaft, and the lock of the lever can be released by a simple operation of swinging the lever again. Therefore, locking and unlocking can be performed with one touch.
