[Industrial applications]

 The present invention relates to a brake lock for a motorcycle or a bicycle.

[0002]

[Prior art]

 In the conventional lock, the tire portion is locked by a chain lock or the like. Therefore, when locking, it is necessary to operate after first descending, and when unlocking, it is necessary to operate before riding, and it is troublesome to bend down.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention provides a lock that can be easily locked and unlocked without the need to bend down while riding, and can be attached to the handle to lock the braking state. is there.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention pulls the brake lever of the two-wheeled vehicle to lock the braking state. The holding member is provided with a grip insertion hollow portion through which the grip of the two-wheeled vehicle can be inserted, and the brake lever insertion empty portion through which the brake lever can be inserted. The lock body is formed by a movable member that is transparently provided, and the movable member is slidably provided on the holding member so that the gap between the grip insertion space and the brake lever insertion space can be shortened. In addition to providing a lock mechanism that can fix the brake lever, it has a key that unlocks the lock mechanism. Note that the grip may also be pressed and fixed by sliding the movable member. In addition, a linear locking tooth is formed on the movable member, and a pawl that biases and engages with the locking tooth serves as a locking mechanism of a ratchet mechanism provided on the holding member so that the key can be rotated. The locking mechanism may be released by moving the claw away from the locking tooth by.

[0005]

[Operation] While inserting the grip into the grip insertion hole, insert the brake lever into the brake lever insertion hole to attach the holding member and the movable member, slide the movable member to the holding member side, and pull the brake lever. The lock mechanism keeps the pressed state and locks. As a result, the brake lever is immobile and the braked braking state can be maintained, so theft can be prevented. In a motorcycle, if the movable member also presses the accelerator grip immovably, the vehicle cannot run even if the brake lever is destroyed, which further prevents theft.

[0006]

【Example】

 Hereinafter, an illustrated embodiment of the present invention will be described. In the present example used in the motorcycle shown in FIGS. 1 and 2, reference numeral 1 denotes a hard plastic holding member having a hard core member 11 built therein, and a grip insertion hole 12 into which an accelerator grip 5 can be inserted is provided at one end side thereof. In addition, the upper and lower slide holes 13 that are transparently provided from the end face on the other end side are opened in the grip insertion hole 12.

Reference numeral 2 designates a horizontal U-shaped movable member made of hard plastic, and a brake lever receiving groove 22 into which the brake lever 6 can be inserted is provided through by vertically arranging a horizontal pressing rod 21 at a distance. is doing. The pressing rod 21 is inserted into the slide hole 13 to connect the movable member 2 to the holding member 1 to form a lock body. It should be noted that the protruding portion 23 is provided on one of the pressing rods 21 and is arranged in the engaging groove 14 that is continuous with the slide hole 13 to prevent the movable member 2 from coming off.

A wheel 31 which is rotated by the key 4 is housed near the center of the holding member 1 with the insertion end surface of the key 4 opened, and a rod member is provided on a support piece 32 projecting from the wheel 31. 33 are connected and are arranged toward the pressing rod 21. The rod body 33 is biased toward the pressing rod 21 side by elastically attaching the spring 35 in the inserted spring box 34 to the projecting piece 36 of the rod body 33, and the claw 37 at the tip of the rod body 33 is pushed to the inner surface of the pressing rod 21. It is engaged with a locking tooth 24 formed long on the side.

A relatively soft plastic finger hook piece 25 is attached to the inner surface of the outer bent portion of the movable member 2 so as to protrude. In addition, the other end surface of the holding member 1 has a recessed shape, and a relatively soft cushion material 15 is attached.

Next, the operation of this example will be described. First, as shown in FIGS. 2 and 3, the accelerator grip 5 is inserted into the grip insertion hole 12 and the brake lever 6 is inserted into the brake lever accommodating groove 22 with the pressing rod 21 pulled out. Then, as shown in FIG. 4, the movable member 2 is pushed toward the holding member 1 and the pressing rod 21 is moved by the slide hole 13.

As a result, as shown in FIG. 1, since the pressing rod 21 presses the accelerator grip 5, the accelerator grip 5 is pressed and held between the inner peripheral surface of the grip insertion hole 12 and the pressing rod 21. . The brake lever 6 is crimped between the cushion material 15 on the end surface of the concave portion of the holding member 1 and the inner surface of the outer bent portion of the movable member 2.

At this time, similarly to the ratchet mechanism, the inclined portion of the locking tooth 24 pushes up the pawl 37 against the spring 35, so that there is no hindrance to the inward movement of the pressing rod 21. Further, when the movable member 2 is pressed, the movable member 2 can be smoothly pressed and moved since the brake lever 6 is pressed simultaneously with the finger hook 25.

When the accelerator grip 5 and the brake lever 6 are held, the movable member 2 is locked because the pawl 37 is locked by the locking tooth 24 of the pressing rod 21 by the urging force of the spring 35, as shown in FIG. Is done. Therefore, the accelerator grip 5 and the brake lever 6 are securely held, and the two-wheeled vehicle is prevented from being stolen because it is locked in the braking state of the brake.

At the time of boarding, it is sufficient to insert the key 4 and rotate a little, and since the wheel 31 rotates a little, the rod body 33 moves upward linearly through the support piece 32 against the spring 35. The claw 37 is disengaged from the locking tooth 24, and in this state, the movable member 2 may be pulled outward. As a result, the pressing rod 21 is separated from the accelerator grip 5, and the brake lever 6 is also returned to its original position. The accelerator grip 5 may be removed from the grip insertion hole 12 and the brake lever 6 may be removed from the brake lever housing groove 22.

As described above, according to this example, the handle portion can be locked in the braking state of the brake, and the locking and unlocking operations can be performed while the passenger is in the vehicle, so that the operation can be performed easily and quickly. Moreover, since the pressing rod 21 also presses and fixes the accelerator grip 5, even if the brake lever 6 is destroyed, the accelerator does not operate, so the safety against theft is high.

Although this example is configured as described above, the present invention is not limited to this. For example, as shown in FIG. 5, a groove structure may be used regardless of the grip insertion space provided in the holding member. The shape and configuration of the movable member are not limited, and it is sufficient that the brake lever can be pressed and held by being pressed and moved to the holding member side. In this case, as shown in FIG. 6, the grip does not come off even if the grip is not pressed and held by the movable member. When the grip is pressed and fixed at the same time by sliding the movable member, the structure is not limited to this example, and the grip may be fixed by pressing the slide member provided in the holding member by the sliding of the movable member. Further, the holding member and the movable member may be made of stainless steel or the like regardless of their materials. It may be made of casting and formed as shown in FIG.

Further, a configuration in which the movable member is slidably provided on the holding member is also appropriate, and a configuration in which the movable member is engaged with the dovetail groove or the like can be adopted. A lock mechanism that can fix the inserted brake lever without moving the movable member is also optional, and as shown in Fig. 5, the movable member and the holding member may be locked with a lock. Further, the brake lock of the present invention can be used not only for motorcycles but also for bicycles and motorized bicycles.

[0018]

[Effect of device]

 According to the present invention, the handle portion can be locked while the brake is being braked, and the locking and unlocking operations can be performed while the passenger is in the vehicle, so that the operation is quick and easy. In the second aspect, since the movable member holds the brake lever and presses and fixes the grip at the same time, the grip does not rotate even if the brake lever is broken, so that the grip is most suitable as a lock for a motorcycle and a motorized bicycle. Further, according to the third aspect, the lock operation becomes easy.
