In other words, there is only one key slot, and when the key is inserted here, turning the key for the first time releases the handle lock, and turning on the key turns on the power of each part. is there.
[0003]
[Problems to be solved by the invention]
In a motorcycle equipped with a steering wheel lock device, even if a person without a key can maliciously break the wiring etc. and start the engine, the motorcycle cannot run satisfactorily as it is, that is, Since the vehicle cannot be stolen, the key slot of the lock device may be broken or a foreign object may be packed due to the stomach.
Also, apart from these man-made actions, rain, dust, mud, etc. may enter the key slot during parking, adhere to and accumulate, clogging the inside, and then the key operation may not be successful. It was rare.
[0004]
The present invention has been made in view of the above circumstances, and includes a lock device that can prevent various failures caused by clogging in a key insertion port, such as damage to a key insertion port due to mischief or the like. The purpose is to provide.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has taken the following measures.
That is, the lock device according to the present invention inserts and unlocks a key by inserting the key into a lock main body having a key insertion port, and the lock main body has a key insertion port between an open state and a closed state. A lid member is provided for switching between the two.
The lock body is provided with a lid lock mechanism, and when the lid member is at least in the closed state of the key slot, the lock body is fixed to the lock body and the lock body is not fixed. And switch between them.
[0006]
To operate the lid lock mechanism, a lock release key is required. Needless to say, the lock release key is provided independently as a separate member from the lock body.
With such a configuration, the key slot of the lock main body can be closed with the lid member when unnecessary, and the key slot can be damaged due to mischief or the like, and the key slot can be blocked. Various failures and the like as causes can be prevented.
The lid member is provided with an opening that can match with the key insertion port of the lock body, and the lid member sets the opening hole with respect to the lock body at a position where the key insertion port matches and a position where the key insertion port does not match. It is assumed to be provided to be rotatable between.
[0007]
Further, the lid member can be configured to have a unique fitting relationship with the lock release key.
By doing so, the lid member can be formed as a thin part such as a disk, and therefore, the lock body can be simplified in structure and reduced in size. Therefore, application to a motorcycle or the like becomes easy.
The lid lock mechanism can be configured to switch between the lid member and the lock body between a fixed state and a non-fixed state by a magnetic relationship generated between the lid release mechanism and the lock release key.
[0008]
It is preferable that this magnetic force relationship uses a repulsive force.
The lid lock mechanism, when the lid member is in a state where the key slot is closed, protrudes and urges a lock piece built into the lock body side toward the lid member side, so that the lid member is pressed against the lock body. In the fixed state, when the lock release key is brought into contact with the lid member, the lock piece is pushed from the lid member side to the lock body side against the projecting urging force due to the magnetic force generated between the lock release key and the lock piece. It is possible to adopt a structure in which the lid member and the lock main body are pushed back and the lock body is not fixed.
[0009]

The polarity arrangement of the lock pieces on the lock body side and the polarity arrangement of the magnets on the lock release key side are combined in a unique matching relationship for each lock device.
The lock release key may be integrally provided on the tail end side of the key that locks and unlocks the lock body.
[0010]
This does not lead to an increase in the number of portable items due to the lock release key, and can prevent loss or the like.
It goes without saying that the lock body can be employed as a start switch and / or a handle locking device for a motorcycle. However, this is not a limitation, and the present invention can be used in all fields as a door lock device or the like.
The lock device according to the present invention may be configured such that the lid member is detachable.
That is, a lid member which is detachable in accordance with the key slot of the lock body and which closes the key slot by wearing is provided independently as a separate member from the lock body. At least one of the member and the lock main body is provided with a lid lock mechanism that switches between a fixed state and a non-fixed state with the lid member mounted on the lock main body, and a lock release key of the lid lock mechanism includes the lock main body and the lock main body. Are independently provided as separate members.

Therefore, only when the key 7 having a unique matching relationship with all the tumblers 12 is inserted from the key insertion slot 5, all the tumblers 12 are pushed back in the reverse biasing direction, so that the inserted key 7 In addition, the rotation of the rotor 9 with respect to the cylinder 8 is allowed.
[0014]
When the rotor 9 rotates, the angular position of the crankshaft 9C protruding at the tail end thereof changes, and accordingly, the joining position of the dead bolt 16 for the handle lock is restricted or released, and thus the handle lock is released. The state can be released.
After releasing the handle locked state in this way, by further turning the key 7 in the same direction, a switch unit (not shown) provided in the cylinder 8 is operated, and each part of the motorcycle 2 is operated. The power supply is turned on.
On the other hand, if the rotor 9 is rotated in the opposite direction, the handle can be returned to the locked state.
[0015]
The key 7 can be pulled out of the key insertion slot 5 only when the handle lock is released. The key insertion slot 5 is provided with a dustproof cover (not shown) that opens and closes by inserting and removing the key 7. However, in the present invention, the structure itself as the lock body 6 as described above is not particularly limited.

That is, as shown in FIG. 6, the lid member 20 can match the opening shape of the opening hole 23 with the opening shape of the key insertion port 5 of the rotor 9 completely, as shown in FIG. If the rotation from this state is performed, it is possible to make the opening shapes of the opening 23 and the key insertion port 5 intersect (orthogonalize) with each other so that they do not match.
The non-coincidence state in which the opening shapes of the opening 23 of the lid member 20 and the key insertion port 5 of the rotor 9 intersect means that the key insertion port 5 is partially closed. There is, therefore, the key 7 cannot be inserted into the key slot 5.
[0019]
As a result, the key insertion port 5 can be switched from the open state (FIG. 6) to the substantially closed state (FIG. 7) and vice versa.
As shown in FIGS. 1 and 2, a positioning action hole in which a small ball 31 can be pushed into a part of the arc-shaped concave portion 26 through a resilient member 30 such as a coil spring is formed in a front end 9 </ b> B of the rotor 9. On the other hand, the lid member 20 has two positions: a position matching the positioning action hole 32 in the above-described open state, and a position matching the positioning action hole 32 in the closed state. Positioning recesses 33 are provided at a plurality of locations, where a part of the arc-shaped projection 25 is cut out.
[0020]
Therefore, when the lid member 20 is in the open state and the closed state, the small balls 31 are engaged with the positioning recesses 33 of the lid member 20 in a state where the small balls 31 are pushed by the resilient members 30, respectively. Retention will be done. In addition, a click feeling and a sound when the small ball 31 is engaged with the positioning concave portion 33 can be obtained.
The lid member 20 is held in contact with the front end 9B of the rotor 9 by a ring cover 37 having an inner flange 36 for holding the lid, and the casing 6 covers the ring cover 37 by a casing 38 so as to cover the ring cover 37. It can be attached to the side.
[0021]
As shown in FIGS. 3 and 4, the front side of the lid member 20 has a unique fitting relationship with the lock release key 22 (the tail end of the key 7).
In the present embodiment, it is assumed that the lock release key 22 has a disk shape and a cutout portion 40 is provided on a part of the outer periphery thereof, and the cover member 20 has a concave portion 41 that can receive the lock release key 22. I have.

As for the magnet 55, a magnet having an S pole and a magnet having an N pole are mixed in various ways. The polar arrangement in which the magnets 55 are provided is combined with a compatible relationship (a relationship in which one is an S pole and the other is necessarily an S pole).
[0024]
The arrangement relationship is different for each product of the lock device 1, that is, is unique.
Therefore, when the key insertion port 5 is closed by the lid member 20 as shown in FIG. 7, the lock piece 52 built in the lock body 6 side (rotor 9) as shown in FIG. The resilient member 51 urges the cover member 20 to protrude into the lock recess 53.
Therefore, the lid member 20 cannot be rotated with respect to the lock main body 6 and is in a fixed state. Thus, the closed state of the key insertion port 5 is maintained.
[0025]
In this state, as shown in FIG. 9, the lock release key 22 is fitted into the concave portion 41 of the lid member 20 and brought into contact with each other, and the magnet 55 of the lock release key 22 is moved to the lock body 6 side (the rotor 9). A magnetic repulsive force is generated between the lock pieces 52 and the lock pieces 52, and all the lock pieces 52 are pushed back toward the lock body 6 against the urging force. Therefore, the lock pieces 52 escape from all the lock recesses 53 of the cover member 20, and as a result, the cover member 20 can be turned (non-fixed state).
Then, while the lock release key 22 is still fitted in the concave portion 41 of the lid member 20, the lock release key 22 is rotated to open the key insertion port 5 as shown in FIG. .
[0026]
Thereafter, the lock release key 22 is once pulled out from the lock main body 6 side, the longitudinal direction is reversed, the key 7 side is inserted into the key insertion slot 5, and the turning operation may be performed.
In the lock device 1 having such a configuration, when the motorcycle 2 is parked or the like, when the lock device 1 is unnecessary (when not in use), the key insertion port 5 of the lock body 6 is closed by the lid member 20. It is possible to prevent various troubles such as damage to the key insertion port 5 due to mischief and the like and clogging in the key insertion port 5 and the like.
