Abstract

PURPOSE:To prevent failure in LOCKing by a user, and to facilitate the handling of an automobile by a dealer by restricting the drawing of a key to a LOCK position or to the condition where a preset process is carried out. CONSTITUTION:A main switch 1 for automobile, for example, is formed in the form of a cylinder lock, while contacts 21, 21 fixed to a roller 19, and contacts 22, 22 which are provided on a terminal board 16, and which are connected with a lead 23, are preferentially connected with each other through the rotation of a rotor 4. LOCKing is carried out by displacing a lock bar 25 through the rotation of the rotor 4, and by thus preventing the actuation of a steering mechanism. The drawing of a key is restricted to a LOCKed condition and to certain conditions: to the position of a key marked with '*'that is known only to a dealer, and to the LOCKed condition with a stopper 54 installed, while steering is possible with the displacement of the lock bar 25 prevented, in both cases.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a main switch used in vehicles such as motorcycles.

(Prior art) For example, a main switch in a motorcycle has a steering lock mechanism integrated into it, and the rotational positions of the key include an ON position to turn on the electrical system, and a F position to turn it off.
Is there a LOCK position that turns on the steering lock mechanism, and is it impossible to remove the key in the ON position?
In the OFF position and the LOCK position, the key can be removed.

However, if the key can be removed even in the F position as described above, there is a possibility that the user may remove the key in the OFF position without locking the steering wheel, which is undesirable in terms of preventing vehicle theft.

In order to prevent forgetting to lock the steering wheel as described in L, the key may not be removed in the OFF position, but may be removed only in the LOCK position.

(Problem to be solved by the invention) However, especially in the case of motorcycles, during the TI registration process and at dealers, the key is removed during transport to prevent the key from being lost. If the key can be removed only when the key is in the LOCK position, there will be an inconvenience that the motorcycle must be transported with the steering wheel locked.

The present invention has been made in view of the above problems, and its purpose is to reliably prevent users from forgetting to lock the steering wheel of a vehicle, and to prevent any hindrance to the handling of vehicles during the distribution process or at dealers. To provide a main switch for a vehicle that does not cause power to turn off.

(Level-L for solving the problem) In order to achieve the objective 2, the first invention provides a dual-purpose main switch that can be operated within a predetermined rotation range by normal key operation.
N, OFF, the key can be rotated to the LOCK position, the key rotation is restricted in other ranges, the steering wheel is locked only when the key is in the OCK position, and the key cannot be removed. It is possible to rotate the key to a spare key operation position provided outside the predetermined rotation range by an operation that releases the restriction on rotation of the key outside the predetermined rotation range. The present invention is characterized in that the steering wheel is unlocked and the key can be removed when the key is in a spare key operating position.

Further, a second invention provides a stopper for preventing the lock pin from being engaged with the lock hole regardless of the key operation in a main switch for a vehicle that locks the steering by engaging the lock pin with the lock hole through key operation. With the member provided and the stopper member removed,
Its feature is that the steering wheel is locked only when the key is in the LOCK position, and the key can be removed.

(Function) According to the first invention, within the range of normal key operations by the user, the key does not come out at the ON and OFF positions, and the LOC
Since the key can only be removed in the K position, it is possible to prevent the user from forgetting to lock the vehicle's steering wheel.

On the other hand, in the distribution process or at a retail store, after performing an operation to release the key rotation restriction, if the user turns the key to a spare key operation position installed outside the key operation range, the steering lock will be activated. Since the key can be removed in the unlocked state, the vehicle can be transported with good work efficiency in the same manner as before with the key removed, and handling of the vehicle will not be hindered.

Further, according to the second invention, if the stopper member is attached when the vehicle is transported during the distribution process before the vehicle is delivered to the user, or when the vehicle is displayed at a dealership, the steering wheel can be locked by the stopper member. Since the vehicle is locked, the vehicle can be freely transported during the distribution process even if the key is removed from the LOCK position.

On the other hand, if the stopper member is removed just before the key is handed over to the vehicle or the user, the key can only be removed in the LOCK position;
□Since the steering wheel is locked in the OCK position, it is possible to prevent the user from forgetting to lock the steering wheel of the vehicle.

(Example) An example of the first invention will be described below based on the accompanying drawings.

Fig. 1 is a longitudinal cross-sectional view of the main switch for a vehicle according to the first invention, Fig. 2 is a plan view of a part of the cylinder of the main switch, and Figs. 3 (a) to (e) are from the leaf F position to the LOCK position. FIGS. 4(a) to 4(c) are explanatory diagrams showing the operating state of the main switch when the key is operated from the LOCK position to the preliminary key operating position. FIGS. .

First, the main switch l based on 1] A and Fig. 2.
To explain the basic structure of the cylinder, in the figure, 2 is a cylinder, and a steel housing sink 3 is fitted in the lower part of the cylinder.

A rotor 4 is fitted into the upper part of the non-torter 2, rotatable and movable up and down.The rotor 4 has a plurality of tumblers 5... 7I

Further, an actuator 7 for a bush lock is engaged with the inner circumference of the cylinder 2 so as to be able to move up and down, and the actuator 7 has a built-in terminal 9 that is pressed against the inner circumference of the cylinder 2 by a spring 8. ing. Furthermore, the decorative plate lO fitted around the rotor 4 on the upper surface of the cylinder 2 has "
"ON", rOFFJ, rLOCKJ are marked. Note that the * mark position opposite to the rOFFJ position on the decorative plate 10 is a spare key operation position, and this * mark is not actually displayed on the decorative board 10, and the existence of this spare key operation position is due to the vehicle. I am only aware of the distribution process and those who follow the sales outlets.

Further, a cam 11 is engaged with the lower part of the rotor 4, and the cam 11 is held by a retaining plate 13 fixed to the cylinder 2 by a hiss 12.
is always urged upward by a spring 14 compressed between this and the cam 11.

Further, an action plate 15 and a terminal block 16 are fixed below the holding plate 13 inside the cylinder 2,
A shaft 17 extends downwardly from the cam 11 through the action plate 15 and the terminal block 16, and a shaft 17 is rotatably supported on the stay house sink 3 at the lower end of the shaft 17. Cam 18 is engaged.

Further, a resin roller 19 is disposed between the action plate 15 and the terminal block 16 and is inserted into the shaft 17 and held therein, and the roller 19 has a contact 21 pressed against the terminal block 16 by a spring 20. These contacts 21.21 are selectively connected to terminals 22.22 provided on the terminal block 16 by rotating the roller 19. Note that REET &123 is connected to the terminals 22 and 22 as shown in the figure.

On the other hand, a slider 24 that engages with the cam 18 and a lock bar 25 that engages with the slider 24 at one end are provided in the house sink 3 so as to be slidable in the left-right direction in FIG. , these slider 24 and lock bar 25 are biased to the right in FIG. 1 by a spring 26. The cam 18, slider 24, lock bar 25, etc. constitute a steering lock mechanism.

Next, the action of the main switch l will be explained based on FIGS. 3 and 4.
key 30 (see Figures 3 and 4) or ON as shown in Figure 2
When the key 30 is in the OFF position, an uneven portion (not shown) provided on the insertion portion of the key 30 engages with the inner circumference of the tumbler 5 -, and the inner circumference of the cylinder 2 engages the tumbler 5 -. Since the outward movement of the key 30 is prevented, it is impossible to remove the key 30, and the lock bar 25 is
The steering lock mechanism is released at the solid line position in the diagram (
off) state.

Therefore, from the state where the key 30 is in the FF position, the third []
When the rotor 4 is pushed down against the elastic force of the splinter 14 as shown in FIG.
It remains in that position due to the frictional force acting between the inner peripheral surface of cylinder 2 and cylinder 2.

Then, when the force pushing down the rotor 4 is released, the third
As shown in figure (b), only the rotor 4 or the spring 14
The elastic force causes the rotor 4 to return to its original position, and the engagement between the stopper 4a of the rotor 4 and the actuator 7 is released, so that the rotor 4 moves toward the LOCK position as shown in FIG. 3(C). It becomes possible to rotate.

By the way, when the rotor 4 is rotated, the cam 11 that engages with it
Before the key 30 or the key 30 reaches the LO (:) position, the actuator 7 rotates together with the cam II as shown in FIG. 3(d).
Because the operator rides on the protrusion 11a, the actuator 7 moves L and returns to its original position. When the rotor 4 rotates to the LOCK position, it engages with another stopper 4b of the rotor 4 or the actuator 7, as shown in FIG. 3(e), so that the rotation of the rotor 4 is locked. 2. In this LOCK position, four parts (not shown) are formed on the inner peripheral surface of the cylinder 2 so that the insertion part of the key 30 and the engaged tumbler 5 can move outward.

Therefore, 1. At the OcK position, the key 30 can be removed, and at this time the lock bar 25 protrudes to the position shown by the chain line in FIG. 1, so the steering lock device is in the on state.

As mentioned above, within the range of normal key operation by the user (within the rotation range from the ON position to the 1 to OCK position), the key 30 cannot be removed from the ON position or the OFF position, and the LOC
Since it is configured so that only the K position iron can come out, it is possible to prevent the user from forgetting to lock the steering wheel.

On the other hand, in the vehicle distribution process or at a dealership, the steering lock can be released by the following operation even with the key 30 removed.

That is, when the rotor 4 is pushed down from the LOCK state against the elastic force of the spring 14 as shown in FIG. 9 (see No. 1121) and the inner peripheral surface of the cylinder 2, it remains in that position due to the frictional force acting between it. Then, when the force pushing down the rotor 4 is released, as shown in Fig. 4 (
As shown in FIG. 4(c), the rotor 4 returns to its original position solely by the elastic force of the spring 14, and the engagement between the stopper 4b of the rotor 4 and the actuator 7 is released, as shown in FIG. 4(c).
As shown in Figure 2, the rotor 4 can be rotated to the preliminary key operation position marked with * in Figure 2. In addition, in this preliminary key operation position, the cylinder 2 is moved so that the tumbler 5...- can be moved outward, similar to the position 10 (:).
Four parts (not shown) are formed on the inner circumferential surface of the holder.

Therefore, in the spare key operation position, the key 30 can be removed and the steering lock is released, so during the vehicle distribution process or at the dealership, the key 30 cannot be removed as before. The vehicle can be freely transported, etc. without causing any hindrance to the handling of the vehicle. still,
The rotation operation from the LOCK position to the reserve key operation position is as follows:
Push down operation of rotor 4 in LOCK position (key 3
0 rotation restriction), the user will not accidentally turn the key 30 to the preliminary key operation position, and the aforementioned user forgetting to lock the steering wheel will be reliably prevented.

Next, an embodiment of the second invention will be described based on FIGS. 5 to 11. In addition, Fig. 5 is a diagram of the vicinity of the main switch of the scooter type motorcycle, Fig. 6 is an enlarged detailed view of section A in Fig. 5, Fig. 7 is a sectional view taken along the line ■ to ■ in Fig. 6, and Fig. 8 is a diagram showing the vicinity of the main switch of the scooter type motorcycle. A sectional view taken along the line ■-vi in Fig. 6. Fig. 9 is a longitudinal sectional view of the main switch.

[This is a sectional view taken along the line XI-X of IJ.

The basic structure of the main switch I according to the present invention will be explained with reference to FIGS. 9 to 11. In the figure, 2 is a cylinder, and a cover 3 is fitted to the lower part of the cylinder.

A rotor 4 is fitted into the upper part of the cylinder 2 so as to be rotatable and movable up and down, and the rotor 4 is provided with a plurality of tumblers 5 and keyholes 6 (see Fig. 10). The tumbler 5.- is pressed outward by a spring (not shown). Also, Cylinder 2's

It is marked with CKJ.

Further, the upper end of a shaft 17 is engaged with the lower part of the rotor 4, and the rotor 4 is always urged upward by a spring 14 compressed between the rotor 4 and the shaft 17. Note that the lower end surface 4a of the rotor 4 and the shaft 17
The upper outer peripheral portions 17a of the two constitute cam surfaces that engage with each other.

Incidentally, the intermediate portion of the shaft 17 constitutes an eccentric portion 17b, and the eccentric portion 17b passes through an elongated hole 31a formed in a flat plate-shaped sliter 31, as shown in FIG.

On the other hand, a lock bar 25 is inserted into the side of the cylinder 2 so as to be freely advanced and retracted in the direction of the arrow shown in the figure.
The end facing into the cylinder 2 is slidably fitted into the groove 31b (see FIG. 11) of the slider 31,
A splinter 26 is provided between the lock bar 25 and the slider 31 in the groove 31b.

Further, a roller 19 that moves together with the shaft 17 is engaged with the lower part of the shaft 17, and a contactor 22, which is pressed against the terminal block 16, is held by the roller 19.

Therefore, the main switch l explained above is either attached to the body side of the l177 section of the scooter type motorcycle 50 as shown in FIG. 5, or the main switch l as shown in FIG. A switch bracket 52 is connected to the switch bracket 52, and as shown in FIG. 8, the lock bar 25 of the main switch 1 is slidably fitted into the boss 52a of the switch bracket 52. enters into the head pipe 51 as shown by the chain line in FIG. 8 by operating a key to be described later, and its tip engages with the lock hole 53a of the steering shaft 53 to prevent the steering shaft 53 from rotating. lock.

By the way, an insertion hole 52b is formed in the upper part of the switch bracket 52, and a plate-shaped stopper member 54 is inserted into the insertion hole 52b. This stopper member 54 is inserted when assembling the motorcycle 50, and the wire 55 tied to it is led out from the gap between the bundle cover 56 and the fender 57 as shown in FIG. is connected to the pull link 58. In addition, when the stopper member 54 is inserted, the tip of the lock bar 25 comes into contact with the stopper member 54 and is prevented from entering the head pipe 51 regardless of the key operation, and the steering lock is always in the released state. It is in.

Therefore, when the stopper member 54 is removed, the main switch 1 is in the LOCKJ position (the first
O figure #! -! The steering wheel is locked and the key can only be removed from the main switch 1 when the main switch 1 is on.

Therefore, if the stopper member 54 is inserted into the switch bracket 52 until the motorcycle 50 is delivered to the user, the lock bar 54 can be inserted into the switch bracket 52 regardless of the key operation as described above.
5 is at rest in the unlocked position as shown in FIGS. 11(a) to (C), so the steering is not locked. Especially when the key is in the LOCKJ position,
Due to the rotation of the eccentric portion 17b of the shaft 17, the slider 31 moves to the left in the figure as shown in 1112I(c), or the lock bar 25 is prevented from moving by the striker member 54. , the splinter 26 is compressed and deformed by the amount of movement of the slider 31, and the splinter 26 is
urges the lock bar 25 to the left in the figure. In addition, Fig. 11 (a) shows a state in which the key is in the "ON" position, and Fig. 11 (b) shows a state in which the key is in the rOFFJ position. I can only pull it out. Also, press the key as shown in Figure 11(e).
From the rOFFJ position shown in , to the rLo shown in UjJ (c)
(: To rotate to the KJ position, it is necessary to push down (PUSH) the rotor 4 (see Figure 9).

Therefore, in the distribution process before the motorcycle 50 is delivered to the user, or at the dealer, the key must be turned to the rLOCKJ position and removed, and at this time, the steering wheel is not locked, so that the first invention is not performed. Similarly, the motorcycle 50 can be transported with the key removed, and workability is not affected.

Then, just before the motorcycle 50 is delivered to the user, hold the bling 58 shown in FIG. 5 and pull the wire 55 to remove the stopper member 54 from the gap between the bundle cover 56 and the fender 57, as shown in FIG. ), the lock bar 25 moves to the left in the figure due to the elastic force of the splinter 26, and engages with the lock hole 53a of the steering shaft 53 as shown by the chain line in FIG. Rotation is prevented by 1k and the steering is locked.

Therefore, when the user operates a key, the key is r
Since it can only be released from the LOCKJ position, it is possible to reliably prevent the user from forgetting to lock the steering wheel, as in the first invention.

(Effects of the Invention) As is clear from the above description, according to the present invention, it is possible to reliably prevent a user from forgetting to lock the steering wheel of a vehicle, and also to prevent any hindrance to the handling of the vehicle in the distribution process or at the dealership. The effect is that it is possible to obtain a main switch for a vehicle that does not cause the main switch to turn off.
