It can be performed at the position, and each operability can be improved.

  According to the invention of claim 6, the rotor can be slid downward by a pressing operation and can be rotated from the off position to the steering lock position in the state of being slid downward. The steering can be locked by the same operation as that of a conventional general-purpose ignition switch device (which displaces the tumbler by inserting a mechanical key).

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The ignition switch device according to the first embodiment can lock engine start, stop or steering in a two-wheeled vehicle. As shown in FIGS. 1 to 3, the rotor 1, the key cylinder 2, and the restricting means. As a pin-shaped member 3, a magnet lock 5, a lock bar R, and a switch mechanism S.

  The rotor 1 is housed in a key cylinder 2 as a casing, and is an on position where the engine of the two-wheeled vehicle can be started, an off position where the engine can be stopped, and a steering lock that locks the steering (handlebar). It can be rotated between positions. On the upper portion of the rotor 1, a knob portion 1a composed of a pair of projecting shape portions formed with a certain distance is integrally formed, and the driver holds the knob portion 1a in an off position. From the off position to the steering lock position.

  Note that the rotor 1 is formed integrally with the upper member 1b by a pin p, and an opening 2b is formed between the knob portions 1a of the upper member 1b (separating portion of the protruding shape portion). . The opening 2b faces a portion where a magnet piece 5a of the magnet lock 5 described later is formed, and the magnet key K can be inserted.

  The pin-shaped member 3 regulates the rotation of the rotor 1 relative to the key cylinder 2 when the rotor 1 is in the off position and the steering lock position. When the magnet lock 5 is in the state shown in FIG. It is in a state of being engaged with the notch 2aa or 2ab formed in the cylinder 2. Further, the pin-like member 3 is biased by the spring 4 toward the rotation shaft side (right side in FIG. 2) of the rotor 1, and the cam 5c moves with the rotation of the magnet lock 5 (see FIGS. 6 and 7). Then, it is configured to retract from the notch 2aa or 2ab to release the locking and allow the rotor 1 to rotate.

  The magnet lock 5 includes a magnet piece 5a that is displaced by the magnetic force of the magnet Kb and is released when the magnet key K (see FIG. 4) having the magnet Kb formed at a predetermined position is inserted. At the same time, the restriction on the rotation of the rotor 1 by the pin-like member 3 can be released. As shown in FIG. 4, the magnet key K has a pair of projections Ka projecting in the radial direction, and these projections Ka can be fitted into a fitting portion 5 b formed on the top surface of the magnet lock 5. Yes.

  Further, a plurality of magnets Kb are insert-molded in a predetermined layout on the front end surface of the magnet key K, and when the projection Ka of the regular magnet key K is inserted into the insertion portion 5b, each magnet Kb is magnet-locked. 5 is set to a position corresponding to the magnet piece 5a formed on the back surface side. The magnet piece 5a is urged upward by a spring 6, and is fitted into a recess formed on the back side of the magnet lock 5 to restrict the rotation of the magnet lock 5, and the magnet Kb When the repulsive force is applied by the magnetic force, the magnetic lock 5 is lowered against the urging force of the spring 6 so that the engagement with the recess is released and the rotation of the magnet lock 5 can be allowed.

  Further, the magnet lock 5 can be rotated together with the magnet key K independently of the rotation operation of the rotor 1 by the knob 1a, and a cam 5c is integrally formed on the periphery thereof as shown in FIG. The pin-like member 3 can be retracted with respect to the notch 2aa (the same applies to the notch 2ab) by the action of the cam 5c due to the rotation of the magnet key K. Further, when the rotor 1 is in the off position and the steering lock position, the pin-like member 3 in the retracted position is protruded by the action of the cam 5c due to the rotation of the magnet key K and is locked to the notch 2aa or 2ab. The rotation of 1 can be restricted.

  That is, when the tip of the magnet key K is inserted through the opening 2b and the projection Ka is inserted into the insertion portion 5b, the restriction of the rotation of the magnet lock 5 by the magnet piece 5a is released, so that the magnet key K can be rotated from this state. In this case, the magnet lock 5 can be rotated. When the magnet lock 5 rotates together with the magnet key K, the cam 5c also moves in that direction, and the pin-like member 3 is retracted from the notch 2aa (or notch 2ab), so that the rotation restriction of the rotor 1 is released. The rotor 1 can be rotated by picking the knob 1a and rotating it.

  Thus, when the rotor 1 rotates from the off position to the on position by rotating rightward (clockwise) while picking the knob 1a, the rotation is transmitted to the switch mechanism S and the movable terminal 10 is rotated. Has been. A plurality of movable contacts 10 a are formed on the movable terminal 10, and the movable contacts 10 a form a predetermined electrical circuit with a fixed contact (not shown) formed on the terminal base 9, It can be started.

  On the other hand, the rotor 1 (including the upper member 1b) is urged upward by the spring 7 and can slide downward against the urging force of the spring 7 by a pressing operation. That is, when a pressing operation is performed while picking the knob portion 1a, as shown in FIG. 9, the rotor 1 including the upper member 1b, the magnet lock 5 having the magnet pieces 5a and the like, and the pin-like member 3 slide downward together. It is configured to be able to. The notches 2aa and 2ab are vertically extended over a predetermined dimension, and interference with the pin-like member 3 due to the pressing operation of the rotor 1 is avoided.

  However, when the rotor 1 is lowered, the lower end of the rotor 1 is fitted with the fitting portion 8a of the shaft member 8, and the shaft member 8 can be rotated when the rotor 1 is rotated to the steering lock position in this state. The shaft member 8 is formed with a crank portion 8b connected to the lock bar R. When the shaft member 8 rotates, the lock bar R protrudes and is formed on a rotation shaft of a steering (handle bar) (not shown). The lock bar R can be inserted into the formed hole and the steering can be locked.

Next, the operation of the ignition switch device will be described.
First, when the rotor 1 is in the off position, as shown in FIG. 5, the pin-like member 3 is locked in the notch 2aa, so that the rotation operation is restricted and the magnet piece 5a is used. The rotation of the magnetic lock 5 is also restricted by the locking. In this state, when the tip of the magnet key K is inserted through the opening 2b and the projection Ka is inserted into the insertion portion 5b, the magnet piece 5a is lowered and the engagement with the magnet lock 5 is released. The magnet lock 5 can be rotated by rotating it.

  When the cam 5c moves with the rotation of the magnet lock 5, the pin-like member 3 is retracted in the direction away from the notch 2aa by the urging force of the spring 4, as shown in FIG. The locking is released and the rotation of the rotor 1 is allowed. In this state, if the rotor 1 is rotated rightward (clockwise) to the on position, the engine can be started.

  On the other hand, when the knob portion 1a is picked and pressed and rotated leftward (counterclockwise), the rotor 1 rotates together with the magnet lock 5 to the steering lock position as shown in FIG. Thereby, the lock bar R protrudes and the steering (handle bar) of the two-wheeled vehicle is locked. In this state, the pin-like member 3 is kept in the retracted state by the urging force of the spring 4, and the protrusion Ka does not coincide with the position of the fitting portion 5b, so that the extraction of the magnet key K is restricted. ing.

  Thereafter, when the finger is released from the knob 1a and the magnet key K is rotated clockwise (clockwise), the magnet lock 5 is rotated and the pin-like member 3 is projected by the action of the cam 5c as shown in FIG. Therefore, the pin-shaped member 3 is locked to the notch 2ab, and the rotation of the rotor 1 can be restricted at the steering lock position. At this time, since the projection Ka becomes a position that coincides with the position of the insertion portion 5b, the magnet key K can be pulled out from the opening 2b, and the magnetic force of the magnet Kb is not exerted by pulling out the magnet key K, and the magnet piece 5a. However, it returns to the initial position by the urging force of the spring 6 and is locked again with the magnetic lock 5 to restrict its rotation.

  On the contrary, if the projection Ka of the magnet key K is inserted into the insertion portion 5b in the state of FIG. 8 and the magnet key K is rotated clockwise, the pin-shaped member 3 is retracted from the notch 2ab and the rotor 1 Since rotation is allowed (see FIG. 7), the rotor 1 can be rotated from the steering lock position to the off position while picking the knob 1a (see FIG. 6). Thereafter, the rotation of the rotor 1 can be restricted in the off position by rotating the magnet key K to rotate the magnet lock 5 and locking the pin-like member 3 in the notch 2aa.

  According to the above embodiment, since the restriction of the rotation of the rotor 1 can be released by the magnet lock 5, the vertical dimension of the ignition switch device as compared with the conventional one that requires a plurality of tumblers in the mechanical key insertion direction. Can be made small and downsizing can be achieved, and since the key hole is not required, the waterproof property can be improved. Moreover, since the knob | pick part 1a formed integrally with the rotor 1 is picked and can be operated, operativity can be improved.

  Here, in the state of FIG. 8 (the state where the rotor 1 is in the steering lock position and the rotation is restricted), the relative position between the magnet Kb and the magnet piece 5a is the state of FIG. 5 (the rotor 1 is in the off position). And a state in which rotation is restricted). That is, when the rotor 1 is in the off position (see FIG. 5) and the steering lock position (see FIG. 8), the magnet key K can be inserted and removed while maintaining the relative position of the magnet Kb and the magnet piece 5a constant. It is.

  Therefore, when the magnet key K is inserted, it is avoided that the magnet Kb does not correspond to the position of the magnet piece 5a. Also, according to the present embodiment, if the magnet Kb and the magnet piece 5a are made to correspond to each other when the magnet key K is inserted at any of the off position and the steering lock position, the magnet Kb and Although the layout of the magnet pieces 5a (corresponding to the key type of the mechanical key) is extremely limited, according to the present embodiment, such a problem can be avoided.

  Further, since the restricting means including the pin-like member 3 is retracted from the notches 2aa and 2ab by the cam 5c of the magnet lock 5 and the engagement with the notches 2aa and 2ab is released, the rotor 1 can be configured with a simple configuration. Can be rotated. Further, the knob portion 1a is composed of a pair of projecting shape portions formed with a certain spacing dimension at the upper portion of the rotor 1, and the magnet lock 5 faces the magnet lock 5 at the spacing portion of the projecting shape portion. Since the K can be inserted, the ignition switch device can be further downsized as compared with the case where the magnet lock 5 is provided at a separate position.

  Furthermore, the rotor 1 can be slid downward by a pressing operation, and can rotate from the off position to the steering lock position while being slid downward. The steering can be locked by the same operation as that of the ignition switch device (the one that displaces the tumbler by inserting a mechanical key), and an erroneous operation can be prevented and the steering lock can be reliably operated.

Next, a second embodiment of the present invention will be described.
As in the first embodiment, the ignition switch device according to the present embodiment can lock the start, stop, or steering of the engine in a two-wheeled vehicle. As shown in FIGS. It is mainly composed of a cylinder 12, a pin-shaped member 3 as a restricting means, a magnet lock 5, a lock bar R, and a switch mechanism S. In addition, the same code | symbol is attached | subjected to the component similar to 1st Embodiment, and those detailed description is abbreviate | omitted.

  The rotor 11 is housed in a key cylinder 12 as a casing. As in the first embodiment, the rotor 11 has an on position where the engine of the motorcycle can be started, an off position where the engine can be stopped, and steering ( It can be rotated between a steering lock position for locking the handlebar). A knob 11a is integrally formed on the rotor 11 in the radial direction of the rotor 11, and the driver can rotate the rotor 11 by holding the knob 11a.

  The key cylinder 12 includes a fixing member 13 extending to the side of the rotor 11, and a magnet lock 5 is disposed on the fixing member 13. Such a magnet lock 5 is disposed so as to face upward through the opening 5a, has a plurality of magnet pieces 5a on the back surface side, and a projection K′a of the magnet key K′a on the upper surface (FIG. 14). The insertion portion 5b into which the reference) can be inserted is formed. As shown in FIG. 14, the magnet key K 'has one protrusion K'a protruding in the radial direction, and a plurality of magnets K'b are insert-molded on the tip surface.

  On the other hand, notches 11ba and 11bb are formed on the outer peripheral surface of the rotor 11. When the rotor 11 is in the off position or the steering lock position, the pin-like member 3 is locked to the notches 11ba or 11bb. The rotation of the rotor 11 is restricted by such locking. When the magnet lock 5 rotates together with the magnet key K ′, the pin-like member 3 moves from the position shown in FIG. 12 to the position shown in FIG. 13 by the action of the cam 5c and retracts from the notch 11ba (or the notch 11bb). To get.

  In the present embodiment, the rotor 11 can be slid downward by a pressing operation, and can be rotated from the off position to the steering lock position while being slid downward. In order to allow such downward sliding, the notches 11ba and 11bb are extended up and down over a predetermined dimension, and interference with the pin-like member 3 due to the pressing operation of the rotor 11 is avoided. .

  Thus, the rotation of the rotor 11 and the magnet lock 5 can be restricted in the off position or the steering lock position, and the pin-like member 3 is notched 11ba (or by inserting the magnet key K ′ and rotating it. By retreating from the notch 11bb) and releasing the engagement with the rotor 11, the rotation operation to the ON position or the steering lock position can be performed.

  According to this embodiment, since the magnet lock 5 is disposed at a position different from the rotor 11, the operation of the magnet key K ′ inserted into the magnet lock 5 and the rotation of the rotor 11 by the knob 11a. The operation can be performed at a separate position, and the operability of each can be improved.

  Although the present embodiment has been described above, the present invention is not limited thereto. For example, in place of the pin-shaped member, when the rotor is in the off position and the steering lock position, the rotation of the rotor relative to the key cylinder is restricted. It is good also as a form regulation means. Further, the knob may be of any shape and form as long as it is formed integrally with the rotor and can be rotated by the driver. Further, the pin-like member as the restricting means in the present embodiment is configured to be displaceable between the locking position and the retracted position by the cam of the magnetic lock, but the pin can be pinned by other means (link mechanism or the like). The shaped member may be displaced.

  A knob formed integrally with the rotor and gripped by the driver to rotate the rotor between the on position, the off position and the steering lock position, and the key when the rotor is in the off position and the steering lock position A restricting means for restricting the rotation of the rotor relative to the cylinder, and a magnet piece that is displaced by the magnetic force of the magnet to release the lock when a magnet key having a magnet formed at a predetermined position is inserted. As long as the ignition switch device is provided with a magnet lock that can release the restriction on the rotation of the rotor by the restricting means, the ignition switch device can be applied to a device with a different external shape or with another function added. .
