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 allowing the key hole to be opened and closed from the outside. As shown in FIG. 5, a housing 1 composed of a case 1a and a cover 1b, a shutter 2, a magnetic lock 3 as a locking means, a magnetic key MK (see FIG. 5) as an unlocking means, and a sheet shape Mainly composed of the member 6.

  The case 1a is made of, for example, a die-cast product, and is fitted into the upper part of the cylinder lock S of the vehicle as shown in FIG. 3, and the key hole Ra formed in the rotor R in the cylinder lock S is directed upward. An insertion hole 1aa that can be exposed is formed, and a boss portion B that is convex upward is integrally formed. The boss B is formed with a plurality of (four in the present embodiment) accommodation holes 1ab in which a plurality of magnets 4 and springs 5 constituting the magnetic lock 3 are accommodated, and an O-ring 10 is formed on the outer peripheral surface thereof. Thus, the annular portion 2e of the shutter 2 can be rotatably fitted.

  The cylinder lock S rotatably holds the rotor R inside, and is rotated in a predetermined direction while inserting a key portion IKa (see FIG. 5) of the ignition key IK through a key hole Ra formed in the rotor R. Then, a predetermined electric circuit is formed, and the vehicle engine can be started. In addition, the code | symbol L in a figure has shown the lock bar which protrudes when it rotates in the direction opposite to the time of engine start, inserting the key part IKa of the ignition key IK in the key hole Ra, and can lock the handlebar of a vehicle. .

  The cover 1b is formed of a predetermined die-cast product, and covers the upper surface side of the case 1a to accommodate the components of the cylinder lock protection device such as the shutter 2 in an internal space formed between the cover 1b and the case 1a. Therefore, a hole 1ba that is formed at a position corresponding to the insertion hole 1aa and allows the key portion IKa of the ignition key IK (see FIG. 5) to be inserted into the key hole Ra, and a hole 1bb that allows the magnet key MK to be inserted are formed. Has been.

  As shown in FIG. 4, the shutter 2 is formed by forming a non-magnetic material into a predetermined shape. By rotating in the housing 1, the shutter 2 is in a closed position (see FIG. 7) and an open position (see FIG. 6). ) For opening and closing the key hole Ra. More specifically, the shutter 2 is integrally formed with a locking hole 2a into which the magnet 4 can be fitted, an opposing surface 2b having a predetermined shape surrounded by the edge wall 2c, and a closing surface 2d.

  When the shutter 2 is attached to the boss B and the shutter 2 is in the closed position, the locking hole 2a engages the shutter 2 by inserting the magnet 4 biased upward by the spring 5. As a result, the shutter 2 is locked at the closed position (regulation of movement relative to the open position). That is, when the shutter 2 reaches from the open position to the closed position, the locking hole 2a becomes a position corresponding to the magnet 4 constituting the magnet lock 3 (locking means) and is locked and locked by the magnet 4. The closed surface 2d is in a position where the hole 1ba is blocked, and the key hole Ra can be covered and protected.

  The facing surface 2b is composed of a flat surface formed at a predetermined portion of the shutter 2 (specifically, the surface opposite to the portion where the locking hole 2a is formed), and has a directionality surrounded by the edge wall 2c. It has a predetermined shape. When the magnet key MK is opposed to the facing surface 2b (in this embodiment, abutting via the sheet-like member 6), the lock on the shutter 2 by the magnet lock 3 is released. It is like that.

  The magnet key MK is for releasing the lock by the magnet lock 3 and moving the shutter 2 from the closed position to the open position. In the present embodiment, as shown in FIG. 5, the resin key in the ignition key IK is made of resin. It consists of the site | part integrally molded by the holding part IKb. The magnet key MK has a facing surface a that faces the facing surface 2b of the shutter 2. The facing surface a has the shape of the facing surface 2b of the shutter 2 (that is, the inner peripheral shape of the edge wall 2c). It can be fitted to the edge wall 2c by having a matched shape. The magnet key MK is provided with a plurality of magnets M at positions corresponding to the magnets 4 of the magnet lock 3, and these magnets 4 make the facing surface a of the magnet key MK face the facing surface 2 b of the shutter 2. In this state, the poles different from the poles on the upper surface side of the magnet 4 are arranged so as to face each other.

  Thus, when the shutter 2 is locked at the closed position, when the magnet key MK is fitted into the edge wall 2c and the opposing surface a is opposed to the opposing surface 2b, the magnet 4 and the magnet key MK Due to the repulsive force with the magnet M, the magnet 4 descends against the urging force of the spring 5, the locking is released, and the lock on the shutter 2 is released. If the magnet key MK is rotated in this state, the shutter 2 is rotated by the fitting with the edge wall 2c and can be rotated to the open position (see FIG. 6).

  The case 1a of the housing 1 is provided with a steel ball 7 urged upward by a spring 8, and when the shutter 2 reaches the open position, a hole formed in a predetermined portion of the shutter 2 is inserted into the hole. The steel ball 7 is fitted, and the shutter 2 can be held in the open position. If the magnet key MK is rotated while fitting the edge wall 2c of the shutter 2 in the open position, the shutter 2 is rotated to the closed position (see FIG. 7), and as described above, the magnet It will be locked by the lock 3.

  The sheet-like member 6 is fixed to the surface 2b of the shutter 2 facing the magnet key MK (unlocking means) by sticking or the like, and the surface thereof (the surface facing the outside from the hole 1bb in the cover 1b). The phosphorescent material is coated on the surface. The phosphorescent material is what is called a so-called nocturnal paint, and can absorb external light such as sunlight as light energy and temporarily accumulate it, and can gradually emit the absorbed light.

More specifically, as the phosphorescent material, for example, a material that emits green light mainly composed of ZnSCu or a material that emits blue light mainly composed of Sr ₂ MgSi ₂ O ₇ can be used. It is applied to the surface of the white sheet-like member 6 with a brush or spray. In addition, since the afterglow time is comparatively long, it is preferable to use a phosphorescent material that emits green light mainly composed of ZnSCu. The sheet-like member 6 is cut (trimmed) into a shape following the shape inside the edge wall 2c of the shutter 2 (that is, the shape of the facing surface 2b) in a state where the phosphorescent material is applied, and an adhesive is applied to the facing surface 2b. For example, it is preferable to use a sheet-like flexible member. Thus, when the magnet key MK is fitted into the edge wall 2 c, the facing surface a of the magnet key MK is opposed to the facing surface 2 b of the shutter 2 while being in contact with the sheet-like member 6.

  Furthermore, in the present embodiment, a phosphorescent material similar to the above is formed on the facing surface a of the magnet key MK (unlocking means) facing the predetermined portion (facing surface 2b) of the shutter 2. More specifically, the phosphorescent material is applied to the surface of the sheet-like member 9 having the same configuration as that of the sheet-like member 6, and as shown in FIG. 5, the sheet-like member to which the phosphorescent material is applied. 9 is adhered to the facing surface a of the magnet key MK (unlocking means) with an adhesive or the like.

  According to the above embodiment, the facing surface 2b of the shutter 2 facing the magnet key MK (unlocking means) is formed of a phosphorescent material that can absorb external light as light energy and diverge the absorbed light (specifically). Specifically, since the sheet-like member 6 coated with the phosphorescent material is disposed), the facing surface 2b of the shutter 2 can be easily visually recognized by the light emitted from the phosphorescent material, and the surroundings such as at night can be seen. The operability of the shutter 2 in a dark state can be improved.

  In addition, the phosphorescent material according to the present embodiment is applied on the sheet-like member 6, and the sheet-like member 6 to which the phosphorescent material is applied is opposed to the magnet key MK (unlocking means) 2 b in the shutter 2. Therefore, the phosphorescent material can be easily formed on the facing surface 2b of the shutter 2 and can be easily applied to an existing cylinder lock protection device.

  Furthermore, the facing surface a of the magnet key MK (unlocking means) facing the predetermined portion (facing surface 2b) of the shutter 2 is a phosphorescent material that can absorb external light as light energy and can diverge the absorbed light. Since it is formed, the operability of the shutter 2 when the surroundings are dark such as at night can be further improved. In particular, in the present embodiment, since the facing surface 2b is formed with directionality, it is easy to visually recognize the magnet key MK so as to match the directionality.

  In the present embodiment, the phosphorescent material is applied on the sheet-like member 9, and the sheet-like member 9 to which the phosphorescent material is applied is a predetermined portion of the shutter 2 in the magnet key MK (unlocking means) ( Since it is fixed to the facing surface a with the facing surface 2b) with an adhesive or the like, it is possible to easily form a phosphorescent material on the magnet key MK and to easily apply it to an existing cylinder lock protection device. Can do.
