The cylinder lock protection device according to the present embodiment is provided above the key hole of the cylinder lock provided in the two-wheeled vehicle, and can protect the cylinder lock by opening or closing the key hole from the outside. As shown in FIG. 8, it has a housing 1, a shutter 2, a magnet lock 3, and an operation button 10, and the shutter 2 can be rotated by a magnet key MK (see FIG. 11).

  The housing 1 is attached so as to cover the rotor R in which the key hole Ra into which the ignition key IK (see FIG. 11) can be inserted is formed, and is mainly composed of a main body 1a and a cover 1b. More specifically, the parts constituting the protection device for the cylinder lock are attached to the main body 1a, and the portion where the key hole Ra of the rotor R is formed is exposed to the cover 1b. An opening a for allowing the magnetic key MK of the magnetic lock 3 to abut (a contact surface 4a) to face the outside and an opening c for projecting the operation button 10 are formed.

  The rotor R can be rotated with the ignition key IK inserted into the key hole Ra. The rotor R includes an on position where the engine included in the two-wheeled vehicle is started, an off position where the engine is stopped, and the vehicle. It can be rotated between lock positions for locking the handle bar. When the rotor R is in the off position, the ignition key IK inserted into the key hole Ra is pressed and pushed, and in this state, the left side in FIG. Has been. When the rotor R moves to this lock position, a lock bar (not shown) in a cylinder body (not shown) in which the rotor is disposed is projected, and the lock bar serves as a rotation shaft of the handle bar. The handlebar is locked by being inserted and locked in a formed lock hole (not shown).

  The shutter 2 can be moved (rotated in this embodiment) between a closed position (see FIG. 9) and an open position (see FIG. 10) within the housing 1, and closes the key hole Ra at the closed position. The key hole Ra can be opened at the open position. As shown in FIG. 6, the shutter 2 has an annular fitting hole 2a. The fitting hole 2a is fitted to the outer periphery of an abutting member 4 to be described later and assembled. The contact member 4 is rotatable about the center.

  The shutter 2 is constantly urged from the open position to the closed position by a spring member (biasing means such as a torsion spring or a coil spring) (not shown), and when the shutter 2 is in the open position, It is configured to be locked. That is, the shutter 2 is formed with a locked portion 2c (see FIG. 6) that can be locked with the locked portion 10a (see FIGS. 9 and 10) of the operation button 10, and when the push button 10 is pressed, The lock is released, and the shutter 2 can be rotated from the open position to the closed position by a spring member (not shown).

  The magnet lock 3 enables the driver 2 to move (rotate in the present embodiment) the shutter 2 in the closed position to the open position by pressing the portable magnetic key MK while abutting it. 2 and 6, the abutting member 4 and the actuating member 5 disposed substantially coaxially in the vertical direction in the housing 1, and the engagement interposed between the abutting member 4 and the actuating member 5. And a stop magnet 6.

  The abutting member 4 has an abutting surface 4a that can abut against the magnet key MK on the upper surface (a surface facing the outside through the opening b), and in the pressing direction of the magnet key MK (downward in FIG. 2). It is movable. The contact member 4 has a plurality of locking holes 4b (four in this embodiment) that can be locked by fitting the upper portion of the locking magnet 6 on the surface (back surface) of the contact member 4 that faces the operating member 5. Have.

  The actuating member 5 is actuated by the movement of the abutting member 4, moves together with the abutting member 4 in the pressing direction of the magnet key MK (downward in FIG. 2), and moves the shutter 2 in the closed position to the open position. To get. Here, the actuating member 5 according to the present embodiment is configured to be able to rotate around the axis by receiving a pressing force against the contact surface 4a of the magnet key MK, and to rotate the shutter 2 from the closed position to the open position. The roller member 5a has a spiral groove 5aa formed on the outer peripheral surface, the movable member 8 has a protrusion 8a, and the interlocking part 5b.

  The roller member 5a is formed of a cylindrical member that can be rotated while moving in the pressing direction of the magnet key MK. The roller member 5a is formed with a spiral groove 5aa on the side surface, and includes a locking magnet 6 and a coil spring on the upper surface. A plurality (four in the present embodiment) of receiving holes 5c corresponding to the locking holes 4b are formed while the biasing means 7 can be stored. In addition, a coil spring s is disposed below the roller member 5a, and when pressed by the magnet key MK, the roller member 5a descends against the urging force of the coil spring s. It has become. In the present embodiment, the member in which the accommodation hole 5c is formed and the member in which the groove 5aa is formed are separated, and the roller member 5a is formed by integrating them. The roller member 5a may be formed by forming the accommodation hole 5c in the upper part of the member in which the groove 5aa is formed.

  The protrusion 8a is formed of a convex portion formed on the movable member 8 (see FIG. 8) that can move in the pressing direction of the magnet key MK (downward in FIG. 2), and is fitted into the groove 5aa of the roller member 5a. The roller member 5a is assembled and rotated about the axis in the process of moving in the pressing direction of the magnet key MK. Thus, when the roller member 5a moves in the pressing direction of the magnet key MK (slids in the axial direction), since the protruding portion 8a is fitted in the spiral groove 5aa on the side surface, the pressing force is in the rotational direction. Thus, the roller member 5a can be rotated while being moved.

  On the other hand, the movable member 8 is assembled by being biased by a coil spring 9 (biasing means) that resists the pressing force from the magnet key MK, and when the roller member 5a is pressed while rotating, the movable member 8 is assembled. 8 is held at a predetermined position, and when the roller member 5a is pressed with a predetermined load or more without rotating, the load is transmitted to the movable member 8 through the protrusion 8a and moved in the pressing direction. It is like that.

  The interlocking part 5b is composed of a convex part that is integrally projected from the roller member 5a, and can be rotated from the closed position to the open position by interlocking the shutter 2 when the roller member 5a rotates. That is, when a regular magnet key MK is pressed while being in contact with the contact surface 4a, the contact member 4 and the actuating member 5 are moved in the pressing direction after the lock by the lock magnet 6 described later is released. At the same time, since the actuating member 5 rotates around the axis, the interlocking part 5b can interfere with a predetermined portion 2b (see FIG. 6) of the shutter 2 in the closed position and can be rotated to the open position.

  When the shutter 2 reaches the open position by pressing the magnet key MK, the locking portion 2c is locked to the locked portion 10a of the operation button 10, and the shutter 2 is held at the open position. Become. Then, after removing the ignition key IK from the key hole Ra, pressing the operation button 10 releases the locking between the locking portion 2c and the locked portion 10a. The contact member 4 and the actuating member 5 are locked by the locking magnet 6 and are locked by the magnet lock 3 while being rotated to the closed position by the means.

  As described above, the locking magnet 6 is housed in the housing hole 5c of the actuating member 5 together with the coil spring s, and its upper end portion is formed from a magnet piece that can be locked with the locking hole 4b of the contact member 4. Thus, it is possible to move from the locking position (see FIG. 12 (a)) to the non-locking position (see FIG. 12 (b)) by magnetism from the magnet key MK that is in contact with the contact surface 4a. . When the locking magnet 6 is in the locking position, the contact member 4 and the operation member 5 are locked to restrict the operation of the operation member 5 (rotation with respect to the contact member 4), and the non-locking position. In this case, the engagement between the contact member 4 and the operation member 5 is released to make the operation member 5 operable (rotatable with respect to the contact member 4).

  As shown in FIGS. 11 and 12, the magnet key MK is composed of a portion integrally formed with the grip portion of the ignition key IK, and has a magnet M inside. Then, as shown in FIG. 12B, when the magnet key MK is brought into contact with the contact surface 4a formed on the surface of the contact member 4, the magnet M and the locking magnet 6 face each other. In addition, the magnet M and the locking magnet 6 are set so that the same poles (S pole and S pole or N pole and N pole) face each other.

  Thus, when the magnet key MK is brought into contact with the contact surface 4 a of the contact member 4, the magnetism of the magnet M reaches the locking magnet 6, and repulsion due to the magnetic force of the magnet M and the locking magnet 6 is achieved. Due to the force, the locking magnet 6 descends against the urging force of the urging means 7 and the engagement with the engagement hole 4b is released, so the magnet key MK abutted on the abutment surface 4a. Thus, the operating member 5 can be rotated relative to the abutting member 4 while moving the abutting member 4 and the operating member 5 in the pressing direction.

  According to the above embodiment, the shutter 2 in the closed position can be moved to the open position by pressing the magnet key MK while being in contact with the magnet lock 3 (the contact surface 4a of the contact member 4). The operability for unlocking the magnet lock 3 and moving the shutter 2 to the open position can be improved as compared with the case where the magnet key MK is brought into contact with the magnet lock 3 and then rotated. .

  In addition, the magnetic lock 3 according to the present embodiment has a contact surface 4 a that can contact the magnet key MK, a contact member 4 that can move in the pressing direction of the magnet key MK, and the corresponding contact member 4. Actuated by movement, moves in the pressing direction of the magnet key MK together with the abutting member 4 and moves the shutter 2 in the closed position to the open position, and the magnet key abutted on the abutting surface 4a It is possible to move from the locking position to the non-locking position by magnetism from the MK, and when in the locking position, the contact member 4 and the operating member 5 are locked to operate the operating member 5. Since it has a locking magnet 6 that releases the locking of the contact member 4 and the actuating member 5 and enables the actuating member 5 to operate when in the non-locking position, it is closed more smoothly. Shutter 2 in position It can be moved to the open position.

  Furthermore, since the operating member 5 according to the present embodiment rotates by receiving a pressing force against the contact surface 4a of the magnet key MK, the shutter 2 can be rotated from the closed position to the open position, so that the shutter 2 slides or the like. Thus, the apparatus can be downsized and the apparatus configuration can be simplified as compared with the apparatus that moves to the open position. In the present embodiment, the operating member 5 is rotated by the pressing operation of the magnet key MK to rotate the shutter 2 from the closed position to the open position. However, the shutter 2 is moved by the pressing operation of the magnet key MK. It may be slid from the closed position to the open position.

  Furthermore, the actuating member 5 according to the present embodiment can be rotated while moving in the pressing direction of the magnet key MK, and has a roller member 5a in which a spiral groove 5aa is formed on the outer peripheral surface, and the roller member. The protrusion 8a that is fitted and assembled in the groove 5aa of the 5a and rotates in the process in which the roller member 5a moves in the pressing direction of the magnet key MK, and the shutter 2 when the roller member 5a rotates, is released from the closed position. Since it has the interlocking part 5b that can be rotated to the position, the pressing force of the magnet key MK can be more efficiently converted into the rotation of the operating member 5, and the shutter 2 in the closed position can be opened more smoothly and reliably. Can be moved to.

  The protrusion 8a according to the present embodiment is formed on the movable member 8 movable in the pressing direction of the magnet key MK, and the movable member 8 resists the pressing force from the magnet key MK. When the locking magnet 6 is in the locked position and pressed against the contact surface 4a of the magnet lock 3 with an excessive force, it can move together with the roller member 5a. The member 8 moves in the pressing direction against the biasing force of the coil spring 9 (biasing means). As a result, the shutter 2 can be maintained in the closed position when a force different from the regular magnet key MK is pressed against the contact surface 4a with an excessive force, so that the roller member 5a is damaged. The crime prevention property can be further improved while preventing the above.

  Although the present embodiment has been described above, the present invention is not limited to this, and the shutter 2 in the closed position can be moved to the open position by pressing the magnet key MK while contacting the magnetic lock 3. Any other mechanism may be used. Further, the protrusion 8a is fitted into the spiral groove 5aa of the roller member 5a to rotate the roller member 5a so that the shutter 2 can be rotated from the closed position to the open position. It is good.

  If it is a cylinder lock protection device that can move the shutter in the closed position to the open position by pressing the magnet key while contacting the magnet lock, it has a different appearance shape or other functions added It can also be applied to things.
