The cylinder lock protector can protect the cylinder lock by opening and closing the keyhole on the outside. As shown in Figures 1 to 7, the protection device mainly comprises a housing 1 having a box portion 1a and a cover portion 1b, a shutter 2, a locking mechanism 3 constituting a magnetic lock, and an opening mechanism. The magnetic key MK (see Figure 2) and the operating button 4.

The box portion 1a made of a molded mold includes an insertion hole 1aa (see Fig. 7) formed substantially at the center thereof, and a magnetic lock projection portion 1ab of a magnetic lock provided in the vicinity of the insertion hole 1aa. A vehicle cylinder lock can be inserted into the insertion hole 1aa, and the insertion hole 1aa allows the keyhole a of the cylinder lock to face upward. The magnetic lock projection portion 1ab is configured such that it includes a plurality of (four in the embodiment) receiving holes 1ac formed in the front end faces thereof for receiving the associated magnets M through the associated springs S, And configured such that the circular portion 3a of the locking mechanism 3 can rotatably fit the outer peripheral surface of the magnetic lock projection portion 1ab. Here, in the second and third figures, reference numeral b denotes an O-ring for sealing between the circular portion 3a of the locking mechanism 3 and the magnetic lock projection portion 1ab.

The cover portion 1b is made of a predetermined mold and is used to cover the upper surface side of the box portion 1a to receive a component or the like of the cylinder lock protection device of the shutter 2 in a The inner space between the box portion 1a and the lid portion 1b. The cover portion 1b includes a hole 1ba, a hole 1bb and a Concave portion 5. The hole 1ba is formed at a position corresponding to the insertion hole 1aa, and a start key (not shown) can be inserted into the key hole a. The insertion portion 3b of the locking mechanism 3 can be inserted into the hole 1bb, and the operation knob 4 is disposed in the recess 5 in a protruding manner.

The locking mechanism 3 is made of a non-magnetic material and is integrally formed with the baffle 2. The locking mechanism 3 includes an insertion portion 3b and a plurality of insertion holes 3c formed on a surface side thereof, and the magnetic key MK (opening mechanism) is engageable with the insertion portion 3b. The insertion holes 3c are formed on the back side of the lock mechanism 3, and the magnets M provided on the front end of the magnetic lock projections 1ab are fitted and fixed in the insertion holes 3c. When the locking mechanism 3 thus constructed is assembled to the magnetic lock projection 1ab, the magnets M pushed up by the springs S can be fitted and fixed in the insertion holes 3c, respectively.

That is, according to this configuration, when the shutter 2 is in the closed position, the receiving hole 1ac and the insertion hole 3c formed on the front end of the magnetic lock projection 1ab will be aligned with each other; and at the closed position, when When the magnets M are respectively moved into the insertion holes 3c, the locking mechanism 3 can be fixed and thereby the shutter 2 can be locked. On the other hand, the magnetic key MK is used to release the locked state of the shutter 2 provided by the locking mechanism 3 and thereby move the shutter 2 from the closed position to the open position. For example, the magnetic key MK is made of a portion integrally formed with a grip portion (a portion made of a resin) of a start key of a two-wheeled vehicle. Further, in the front end of the magnetic key MK, a plurality of magnets m are embedded in positions corresponding to the magnets M, respectively. These magnets m are provided such that, in a state in which the magnetic keys MK are fitted into the fitting portion 3b of the lock mechanism 3, the polarities on the upper surface side of the magnets M are different. The polarity of the magnet m is opposite to the polarity of the upper surface side of the magnets M.

With this configuration, when the magnetic key MK is inserted into the embedded portion 3b in a state where the locking mechanism 3 is locked, the repulsiveness between the magnets M and the magnet m disposed in the magnetic key MK is generated. The magnets M are lowered against the thrust of the springs S. While the magnetic key MK is rotated, since the embedded portion 3b is engaged with the magnetic key MK, the locking mechanism 3 rotates together with the rotation of the magnetic key MK, so that the locking mechanism 3 can Rotate with the baffle 2.

The baffle 2 made of a non-magnetic material and integrally formed with the locking mechanism 3 is disposed at a position for covering the keyhole a when it is in the closed position, so that when the locking mechanism 3 is When the magnetic lock protrusion portion 1ab is fitted and the locking mechanism 3 is rotated around the magnetic lock protrusion portion 1ab, the shutter 2 can be in a position for closing the hole 1ba of the cover portion 1b (a closed position: 7 is shown in the position shown by the solid line) and moved away from the hole 1ba to open the hole 1ba (an open position: a position indicated by a double-dotted line in FIG. 7), whereby the baffle 2 The keyhole a can be opened and closed by the outside. Here, the overall structure of the baffle 2 can be arbitrarily changed depending on, for example, the overall shape and size of the casing 1 and the configuration of other remaining constituent elements of the protective device.

The operating button 4 is integrally formed with the baffle 2 and the locking mechanism 3 as a single member, as shown in Figures 4 and 5, and is provided by the locking mechanism 3 and laterally protruded by the locking mechanism 3. Part of the composition. A vehicle driver can pinch and operate the operation button 4, and the operation button 4 is configured such that it can be positioned at a first position for positioning the shutter 2 at the open position (one at Moving between the position indicated by the double dotted line in Fig. 7) and a second position (the position shown by the solid line in Fig. 7) for positioning the shutter 2 at the closed position .

That is, the operation knob 4 is configured such that when the operation knob 4 is moved from the first position to the second position, the shutter 2 can be moved from the open position to the closed position. Here, in this embodiment, after the operation of moving the shutter 2 from the open position to the closed position by the operation button 4 and thus releasing the locked state of the shutter 2, the magnetic key MK is used to make The operation of the shutter 2 from the closed position to the open position. However, it is also possible to use a structure in which the operation of the operation panel 4 is performed to perform the two operations of the shutter 2 (the opening and closing operations of the shutter 2).

According to this embodiment, the recess 5 is formed in the surface F of the casing 1 (when the casing 1 is viewed from the upper surface of the cover 1b), and at the same time, the operation knob 4 is protrudedly disposed therein. Inside the recess 5 and in the recess 5 (in other words, the operating range of the operating button 4 is defined in the recess 5). That is, the operating button 4 can be moved between a first position for positioning the shutter 2 at the open position and a second position for positioning the shutter 2 at the closed position. Turn the shutter 2 on and off.

The recess 5 is a portion having a bottom surface at a position below the surface F of the casing 1 (the cover portion 1b) through the wall surfaces 5a and 5b, and the recess portion 5 also includes a periphery thereof and is slightly higher than the wall surfaces. The protruding portion 5c of 5a and 5b. Here, between the wall surface 5b and the end portion of the protruding portion 5c, a small-sized gap A is provided, whereby the water collected in the recess 5 can be discharged from the gap A. However, it is also possible to prevent the water from being formed without forming the protruding portion 5c. The structure that is collected in the recess 5.

Further, the operating button 4 is configured to be in proximity to or in contact with the baffle 2 when it is positioned at a second position (the position shown by the solid line in FIG. 1) for positioning the baffle 2 in the closed position. The wall surface 5a of the recess 5. This makes it difficult for the operation button 4 to be operated from the second position to the first position. Thus, the third party can be prevented from illegally operating the operation button 4 by a tool or the like, and the crime prevention effect of the protection device can be further enhanced.

Moreover, according to this embodiment, the casing 1 includes the casing portion 1a and a cover portion 1b for covering the surface side of the casing portion 1a; and as shown in Fig. 3, the casing portion 1a and the lid portion 1b are vertical The directions are combined to thereby form a window portion P, and the operation knob 4 is protrudedly set in the recess portion 5 through the window portion P. That is, a notch portion connecting the recess portion 5 is formed in the wall surface of the cover portion 1b, and a protruding portion B is formed along the notch portion, and the protruding portion is disposed on the box portion 1a and The box portion 1a is protruded, whereby the window portion P through which the operation knob 4 can be inserted is formed by the vertical combination of the box portion 1a and the lid portion 1b. Therefore, in the molding operation of the casing 1, the direction in which the mold is removed can be set in one direction (ie, it is not necessary to use another mold for forming the window portion P), thereby contributing to the casing. 1 molding operation. In this case, the upper surface of the protruding portion B is used to form the recess 5.

According to the foregoing embodiment, since the recess 5 is formed in the surface F of the casing 1 and the operation knob 4 is formed convexly and can be operated in the recess 5, even when the operation knob 4 is protruded in the recess 5 The amount is determined, and the amount of the protrusion of the operation knob 4 from the surface F of the casing 1 can also be reduced to zero or can be reduced as much as possible, so that the operational efficiency of the operation knob 4 can be maintained. In addition, Since the operating button 4 is projectingly disposed and operable within the recess 5, the operating button 4 can be prevented from laterally protruding from the housing 1, which prevents the operating button 4 from driving with the vehicle and other remaining components of the vehicle. The component interferes.

Further, since the baffle 2, the locking mechanism 3, and the operating button 4 are integrally formed as a single member, the structure of the embodiment can be simplified not only when compared with the structure formed separately from these elements, and the baffle 2 is opened by the opening The operation of the position to the closed position, the locking operation by the locking mechanism 3, and the operation of the shutter 2 from the closed position to the open position can also be performed more smoothly and reliably.

Although the cylinder lock protection device of this embodiment has been described herein, the present invention is not limited thereto, and for example, without a rotary operation knob 4, a linearly slidable operation button can be used. However, even in this case, a recess must be formed in the surface of the housing and the operating button must be projectingly and operable within the recess. Further, in this embodiment, although the magnetic lock for fixing the magnets M to the lock mechanism 3 is used as the lock mechanism, other types of lock mechanisms may be used instead of this.

Further, according to this embodiment, an arc-shaped expansion portion d is formed on the periphery of the hole 1bb into which the insertion portion 3b of the lock mechanism 3 can be inserted (see Figs. 1 to 3). However, in addition to this, it is also possible to use a hexagonal extension when viewed from above, as shown in Figures 8 and 9. Here, the expanded portion may have other shapes than the curved shape and the hexagonal shape.
