Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a gripping lever used for disengaging the parking brake of a motorcycle or the clutch of a three-wheeled farm vehicle.

The conventional gripping lever locking device focuses on the fact that when the gripping lever is squeezed, a gap is created between the lever and the lever holder, and a shaft or a plate provided on the lever holder side is inserted into the gap. However, in such a conventional gripping lever locking device, since the locking portion is located on the lever holder side, it is difficult to set the gripping lever with the hand that grips it, which means that the locking device must be operated with one hand. It had the disadvantage that it was difficult to In particular, when the winter cover is attached to the handle grip, such an operation is almost impossible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a locking device for a grasping lever that can be easily locked with the hand holding the grasping lever in order to eliminate such drawbacks. A locking pin and a locking lever are provided, the grasping lever is formed into a substantially L-shape, the tip of the grasping lever is pivoted to the lever holder, and the locking pin is attached to a corner of the grasping lever via a shaft. The distal end of the grasping lever from the shaft serves as a lever holder locking part, and the rear end serves as an engaging piece, and the engaging piece of the lock pin is arranged in the grasping direction of the grasping lever. and the lock lever is pivoted via a shaft at a position slightly rearward of the pivot position of the lock pin on the grasping lever, and a distal end of the lock lever relative to the shaft serves as an engaging portion. The rear end portions of both lock levers are used as operating portions, and the engaging portion of the lock lever is latched onto the locking piece portion of the lock pin, and the lock pin is operated by swinging the operating portion of the lock lever in the direction of the grasping lever. This is a gripping lever locking device which swings an engaging piece portion of the locking lever in a direction opposite to the gripping lever, and engages and locks the lever holder locking portion of the lock pin on the lever holder.

Embodiments of the present invention will be described below based on the drawings. In the figure, reference numeral 11 denotes a gripping lever locking device, and the gripping lever locking device 11 has a lever holder 13 and a gripping lever 15. The gripping lever 15 is approximately L-shaped, and a support portion 17 and a gripping portion 19 are formed at each corner thereof. The tip of the support portion 17 is fitted into the opening of the lever holder 13 and is pivotally supported by a shaft 19a. Further, an L-shaped locking pin 21 is attached to the outer corner of the grasping lever 15, and the shaft 22 is biased by a spring (not shown) in the gripping direction of the grasping lever 15.
It is supported by The lock pin 21 is provided with a lever holder locking portion 23 on the lever holder 13 side with the pivot portion as a boundary, and a locking piece 25 with which a lock lever 29, which will be described later, engages is provided on the opposite side. Furthermore, a locking piece 25 of the locking pin 21 is located near the corner of the gripping portion 19 of the gripping lever 15.
A lock lever 29 having an engaging portion 27 that engages with the lock lever 29
is pivotally supported by a support shaft 31 so as to be rotatable in the gripping direction of the gripping lever 15 . In addition, lock lever 2
At 9, an operating section 33 is provided on the side opposite to the engaging section 27 with the support shaft 31 as a boundary.

Incidentally, reference numeral 35 is an interlocking wire for operating the brake or clutch, and this interlocking wire 35
The end thereof is locked to the corner of the gripping lever 15.

2 to 4 are views showing other embodiments of the present invention, in which a pair of locking pieces 25, 25 are attached to a lock pin 21.
is formed, and an L-shaped lock lever 2 is formed.
An engagement shaft 37 that engages with the locking pieces 25, 25 is provided at the corner portion of 9. Since the rest is the same as the first embodiment, the same reference numerals are given to the members corresponding to the first embodiment, and the description thereof will not be repeated.

When locking the grasping lever locking device 11 according to the present invention, the grasping lever 15 is grasped in the direction A with the entire palm of the hand to form a gap between the lever holder 13 and the corner of the grasping lever 15. After that, by pulling the operating part 33 of the lock lever 29 toward you with your index finger, the engaging part 27 of the lock lever 29 will be brought into contact with the engaging piece 25 of the lock pin 21, or the engaging shaft 37 of the lock lever 29 will be brought into contact with the engaging piece 25 of the lock pin 21. , 25. As a result, the lever holder locking portion 23 of the lock pin 21 comes into contact with the end surface of the lever holder 13 against the urging spring, and acts like a rod, preventing the gripping lever 15 from returning to its original position, and the locking device is locked. Ru.

In addition, when releasing such a locking device, if the grasping lever 15 is strongly grasped in the direction A to further widen the gap between the lever holder 13 and the corner of the grasping lever 15, the locking lever 29 and the locking pin 21 will be released. It can be easily released by the action of the included spring.

Since the gripping lever locking device according to the present invention is constructed as described above, first, by gripping the gripping lever, a slight gap is created between the tip corner of the gripping lever and the lever holder. In this state, if the operating part of the lock lever is swung in the direction of the gripping lever using your index finger, etc.
The engaging portion of the lock lever pushes up the locking piece of the lock pin and swings in the direction opposite to the gripping lever, and as a result, the lever holder locking portion of the lock pin enters the gap between the lever holder and the gripping lever. Since it is latched into this gap, the gripping lever can be locked in the gripped state.

That is, in the gripping lever locking device according to the present invention, as the locking means for the gripping lever, the lock pin and the locking lever are each pivotally supported on the gripping lever via independent shafts, so that the operation part of the locking lever can be easily operated. Since the opening angle with respect to the grasping lever can be made small, this operating portion is located close to the locking lever, and as a result, the operator can easily operate the locking lever with the index finger of the hand that is grasping the grasping lever.
