Description

[Detailed Description of the Invention] A. Purpose of the Invention (1) Field of Industrial Use The present invention relates to a handle lock device for a motorcycle, which operates in conjunction with an ignition switch operated by an ignition key.

(2) Related Art A handlebar lock device for a vehicle is well known in the related art, and usually has a structure that operates in conjunction with an ignition switch using a cylinder lock. That is, for example
As seen in Japanese Patent No. 4118, a lock position is added to an ignition switch having an off position, an on position, a start position, etc., and the ignition key must be rotated to the lock position to complete locking of the handle. It has been proposed that the key is configured so that it cannot be removed.

(3) Problems to be Solved by the Invention By the way, when it is necessary to move a motorcycle at a store or the like with the ignition key removed, if the handle lock device of the above method is installed, the ignition key can be removed. In this state, the steering wheel is always locked, which makes it difficult to move the vehicle. Further, in a motorcycle, it is necessary to remove the ignition key at the time of refueling, but in the handle lock device of the above system, there is an inconvenience that refueling is performed while the handle is locked.

In order to avoid such inconvenience, it is conceivable that the ignition key can be removed even when the ignition switch is in the off position.However, in this case, the ignition key is accidentally turned off when the vehicle is parked or when the vehicle is left. There is a risk of removing the key.

The present invention has been made in view of the above circumstances, and provides a handle lock device for a motorcycle which allows an ignition key to be removed without locking the handle and which does not accidentally remove the ignition key. The purpose is to do.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above object, the invention is capable of selecting at least an on-position, an off-position, and a lock position by an ignition key. It operates in conjunction with an ignition switch that allows the ignition key to be inserted and removed,
In a handlebar lock device for a motorcycle for locking a handle when the ignition switch is in a lock position, a restriction surface for restricting insertion / removal of an ignition key when the ignition switch is switched from an on position to an off position, and an ignition key The present invention is characterized in that a stopper member having a release surface that allows insertion and removal of the ignition key when the switch is switched from the lock position to the off position is provided.

(2) Operation According to the present invention having the above-described configuration, when the ignition switch is in the lock position and the handle is locked, the ignition key can be freely inserted and removed as in the conventional case.

When the engine is stopped by switching the ignition switch from the on position to the off position, the ignition key cannot be removed in this off position, so it is necessary to further switch the ignition switch to the lock position and remove the ignition key. Therefore, there is no risk of accidentally removing the ignition key. Further, since the ignition key can be removed by further switching the ignition switch from the lock position to the off position, in this state, the motorcycle can be moved with the ignition key removed.

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The click ball 12 that is elastically urged upward is housed in the recess 8a formed in the. The ignition switch S is Stable stop at multiple positions such as on-position P ₁ , off-position P ₂ , lock position P _3, etc., which will be described later. When the ignition switch S is in the lock position P ₃ , the lock bar 7 projects from the side wall of the lock body 1 to lock the handle (not shown). Further, when the ignition switch S is switched between the on position P ₁ and the off position P ₂ , the conduction between the terminals 11 is connected / cut off to start / stop the engine.

As is apparent from FIG. 6 (A), the cylinder 5 has an insertion hole 5c for the ignition key K extending in the axial direction and five sliding grooves 5d so as to intersect the insertion hole 5c.
Are formed at equal intervals. A plate-shaped tumbler 13 having an insertion hole 13a for the ignition key K formed in the center thereof is slidably held in each sliding groove 5d, and a spring 14 projects from the sliding groove 5d to form the lock body 1. tumbler relief is fitted in the groove 4 _1. And Thus, although the rotation of the cylinder 5 by the engagement of the tumbler 13 and the tumbler escape grooves 4 ₁ is restricted in this state, the cylinder 5
Inserting the hole 5c inserting the ignition key K in order to retract the tumbler 13 abuts the engaging edge 13b of the tumbler 13 in which the reference valleys K ₁ is from the corresponding tumbler escaping grooves 4 _1, cylinder 5 is rotated in the It becomes possible. At this time, since the engaging edges 13a of the five tumblers 13 are formed at different positions so as to correspond to the heights of the respective code valleys K ₁ of the ignition key K, different ignition keys K are inserted. In case one of the tumblers
13 remains in the tumbler relief grooves 4 ₁ , 4 ₃ and cylinder 5
Is restricted.

As is apparent from FIG. 2 as well, a substantially cylindrical stopper member 15 is rotatably supported inside the lock body 1 in parallel with the cylinder 5. Stopper member 15
The peripheral surface of is composed of a partially cylindrical restriction surface 15a and a planar release surface 15b in which the restriction surface 15a is cut out. Then, the state where the release surface 15b faces the cylinder 5 (6th
Figure (A) the stopper member 15 in the reference) is completely spaced from the tumbler escape grooves 4 _1, but the state in which the stopper member 15 is rotated (FIG. 4 (A)) is for escape grooves regulating surface 15a is tumblers It is designed to project into 4 ₁ . And Thus, in this state because is restricted to tumbler 13 to be fitted to the sliding groove 5d is freely sliding in the escape grooves 4 within ₁ tumbler, making it impossible to insertion of the ignition key K.

Furthermore, as will be apparent by referring also to FIG. 6 (B),
On the restriction surface 15a and the release surface 15b of the stopper member 15, an upper protrusion 16 and a lower protrusion 17 are provided so as to be axially separated and out of phase with each other. On the other hand, the reduced-diameter portion 5e formed in the cylinder 5 so as to face both the projections 16 and 17 comes into contact with the two upper cams 18 ₁ and 18 ₂ and the lower projection 17 that can come into contact with the upper projection 16. Two possible lower cams 19 ₁ and 19 ₂ are projected. Then, the pair of upper cam 18 ₁ and lower cam 1
9 ₁ , and the other pair of upper cam 18 ₂ and lower cam 19 ₂ are arranged at positions separated from each other in the circumferential direction of the cylinder 5.

Next, the operation of the embodiment of the present invention having the above configuration will be described.

As shown in FIGS. 3 (A) and 3 (B), when the ignition key K is in the on position P ₁ , the tumbler 13 mounted in the sliding groove 5d of the cylinder 5 has its both ends in the cylinder support hole 1a. Since the abutment is restricted and the sliding is restricted, the ignition key K cannot be inserted or removed. At this time,
Regulating surface 15a of the stopper member 15 protrudes into the tumbler escaping groove 4 _1.

From this state, turn the ignition key K to the off position P ₂
When rotated to, as shown in FIGS. 4 (A) and (B),
Since the lower cam 19 ₁ formed in the cylinder 5 slip through the lower portion of the upper projection 16 formed on the stopper member 15, the stopper member 15 is only the cylinder 5 while keeping its position is rotated counterclockwise. In this state, the both end portions of the tumblers 13 facing the tumbler escape grooves 4 _1, 4 _3, free sliding of the tumblers 13 to the regulating surface 15a of the stopper member 15 protrudes tumbler escaping groove 4 in ₁ Movement is regulated,
The ignition key K cannot be inserted or removed.

Ignition key K further rotates to lock position
When it reaches P ₃ , as shown in FIGS. 5 (A) and 5 (B), the upper cam 18 ₂ provided on the cylinder 5 abuts on the upper projection 16 provided on the stopper member 15, so that the stopper member 15 is released. Liberation surface
15b is rotated to a position facing the cylinder 5. Thus at the same time as closure of the tumbler escaping groove 4 ₁ by regulating surface 15b of the stopper member 15 is released, the tumbler 13
Free sliding is allowed by the opposite ends thereof opposed to the groove 4 _2, 4 ₄ relief tumbler, the ignition key K
Can be inserted and removed.

When the ignition key K is rotated in the opposite direction from the lock position P ₃ to the off position P ₂ , as shown in FIGS. 6 (A) and 6 (B), the upper cam 18 of the cylinder 5 is moved.
_{When 2} passes through the upper part of the lower protrusion 17 of the stopper member 15, only the cylinder 5 rotates clockwise while the stopper member 15 maintains its position. And Thus, since the both end portions of the tumblers 13 in this state with facing the tumbler escape grooves 4 _1, 4 _3, clogging of the tumbler escaping groove 4 ₁ regulatory surface 15a of the stopper member 15 is released, the ignition key K Can be inserted and removed. That is, as shown in FIG. 7, even at the same off-position P ₂ , when the ignition key K is rotated from the on-position P ₁ side to the off-position P ₂ , the restriction surface 15 of the stopper member 15
The ignition key K can be inserted / removed by a, but when the ignition key K is turned from the lock position P ₃ side to the off position P ₂ , the stopper member 15
The release surface 15b allows the ignition key K to be inserted and removed.

When the ignition key K is turned from the off position P ₂ to the on position P ₁ , the lower cam 19 ₁ moves to the lower protrusion 1
The stopper member 15 is rotated by engaging 7 and returns to the state of FIGS. 3A and 3B in which the ignition key K cannot be inserted or removed.

Although the embodiments of the present invention have been described in detail above, the present invention can be modified in various ways without departing from the present invention described in the claims for utility model registration.

For example, the number of tumblers 13 mounted on the ignition switch S is not limited to five and can be changed as appropriate. The positions where the cylinder 5 can be stopped are the on position P ₁ , the off position P ₂ , and the lock position in the embodiment.
It is possible to set appropriately other than P ₃ .

C. Effect of the Invention According to the present invention described above, when the ignition key is turned from the on position to the lock position and pulled out, the handle is automatically locked, and the ignition key can be turned from the lock position to the off position. For example, since the ignition key can be inserted / removed even in the off position where the handle is not locked, it is possible to move the motorcycle with the ignition key removed at a store or the like. Moreover, not only does the inconvenience of refueling with the steering wheel locked while refueling disappear, but there is no risk of the driver accidentally pulling out the ignition key at the off position when leaving the motorcycle.
