[Patent Document 1] JP-A-11-044132 However, the above-described conventional cylinder lock protection device has the following problems. That is, since the operation button is disposed on the end surface of the baffle plate perpendicular to the sliding direction of the baffle plate, and also because the magnetic lock system is disposed on the side surface side of the baffle in the sliding direction of the baffle plate Therefore, the overall size of the device becomes large. Recently, the demand for not only the sliding range of the baffle but also the overall size of the protective device has been increased. SUMMARY OF THE INVENTION J 10 SUMMARY OF THE INVENTION One or more embodiments of the present invention provide a cylinder lock protection device that not only obtains the sliding range of the baffle but also reduces the overall size of the protection device. According to one or more embodiments of the present invention, a cylinder lock protection device 15 includes: a casing 1 disposed on an upper side of a key hole a formed in a cylinder lock; and an insertion hole laa, lba, Formed substantially in the center of the housing 1 for inserting a starter key into the keyhole a; a shutter 2 is slidable substantially linearly within the housing 1 and can be closed The closing position of the insertion holes laa, lba is moved between an open position for opening the insertion holes laa, lba 20 to open and close the key hole a; and the pushing device S1 is used for the baffle 2 The closing position is pushed to the open position; an operating button 3 is protruded by the baffle 2, and is used to oppose the pushing force of the pushing device S1, and the baffle 2 is operated from the open position to the closed position; The mechanism 6 is configured to lock the baffle 2 in the closed position; and the opening device 200940393 ΜΚ 'can release the locked state of the baffle generated by the locking mechanism 6. The operation button 3 is disposed on one side of the shutter 2 in the sliding direction of the shutter 2, and the locking mechanism 6 is disposed on the other side of the jaw 2. According to the foregoing cylinder lock protection device, there are not only operation buttons provided on the shutter side in the vertical direction of the shutter 5, but also a locking mechanism positioned on the other side of the shutter. With this configuration, the operating button and the locking mechanism are disposed with the shutter therebetween, so that not only the sliding range of the shutter but also the overall size of the protecting device can be reduced. Further, the locking mechanism 6 may include a fixing device 4 for fixing the shutter 2 at the closed position, and a locking device 5 for releasing the fixed state of the jaw by the fixing device. When the locking mechanism includes a fixing device for fixing the baffle at the closed position, and a locking device for releasing the fixed state of the baffle generated by the fixing device, the fixing device fixes the baffle The force required 15 and the force required by the locking device to release the fixed state of the baffle can be set separately such that these forces can be set according to their respective optimum forces. Further, the casing 1 may include a recess 7 formed on a surface of the casing, and the operation button 3 may protrude in the recess 7 to be operable. § The breaking body includes a recess formed on a surface of the housing, and the 2 〇 operating knob is formed to protrude in the recess 7 to be operable, and the protrusion of the operating button can be controlled, which prevents the operation The button interferes with a vehicle driver and other constituent elements of a vehicle. In addition, the baffle 2 may include a notch portion 2c having a shape corresponding to the insertion hole, and the notch portion 2c may be aligned with the insertion hole when the baffle 2 is at the position of the opening 200940393 . When the baffle includes a notch portion having a shape corresponding to the insertion hole, and the notch portion is aligned with the insertion hole when the baffle is at the open position, the overall protection device can be further reduced size. 5 Other aspects and advantages of the present invention will be apparent from the following description, drawings, and claims.

Fig. 6 is a cross-sectional view taken along line VI-VI of Fig. 1 (the right half of the plane of Fig. 6 is a front view). [Embodiment 3] Detailed Description of Embodiments 200940393 An embodiment of the present invention will be described below with reference to the drawings. 5 ❹ 10 15 The cylinder lock protection device of this embodiment is disposed on the upper side of the keyhole of the cylinder lock disposed in the two-wheeled vehicle, and the keyhole can be opened and closed from the outside according to the cylinder lock protection device. Thereby the cylinder lock can be protected. As shown in Figures 1 to 6, the cylinder lock protection device mainly comprises a casing 1 having a box portion 1a and a cover portion 1b, a baffle 2, an operating button 3, and a fixing device 4; The locking mechanism 6 of the locking device 5, a coil spring S1 as a pushing device, and a magnetic key as an opening device (see Fig. 6). As shown in Fig. 2, the box portion made of a molded mold includes not only an insertion hole laa (see the 3rd to 5th circles) substantially formed in the center thereof, but also includes a setting in the insertion. The magnetic lock protrusion part lab near the hole laa (see Figure 6). A cylinder lock 8 disposed in a vehicle can be inserted into the insertion hole laa' and the insertion hole iaa can also face the keyhole "a" of the cylinder lock above the insertion hole laa. The magnetic lock projection portion lab includes a plurality of (four in the embodiment) receiving holes lac on the front end surface thereof for receiving the associated magnet M through its associated spring S3; and the magnetic lock projection portion The work is also configured such that the circular portion 5a of the locking device 5 can rotatably fit the outer peripheral surface of the magnetic lock projection portion lab. Here, in Fig. 6 and Fig. 2b, a ring for sealing between the circular portion of the locking device 5 and the magnetic locking dog portion 1 ab is shown. a cover portion lb made of a predetermined mold molding covers the front side 2 of the box portion u to receive components of the cylinder lock protection device such as the baffle plate 2 - formed in the box portion 1a In the inner space between the cover portions lb. The cover portion 1b includes a hole 1ba formed at a position corresponding to an insertion hole 1aa for inserting a start key (not shown) into the keyhole "a" of 200940393, wherein the locking device can be inserted therein The hole 1bb of the fitting portion 5a of the 5, and the operation knob 3 are provided in a recessed portion 7 in a protruding manner. As shown in Figures 3 to 5, the baffle 2 can slide substantially linearly in the right and left directions of the housing 1 in the housing 1, in particular, a shutter can be used to close the hole. The closed position (one position shown in FIG. 3) is moved between an open position (a position shown in FIG. 5) for opening the hole lba, whereby the keyhole can be opened and closed. a". As for the structure of the baffle 2, not only the operation button 3 but also the side surface 2a (the lower surface in FIGS. 3 to 5) of the baffle plate 20 extending in the sliding direction of the baffle 2 is integrally formed. Further, a fixing recess 2ba fixed by the fixing means 4 is formed on the other side surface 2b (an upper surface in Figs. 3 to 5) on the side opposite to the one side surface 2a. Further, on the right end side of the baffle 2 in Figs. 3 to 5, a coil spring 15 S1 (pushing means) for pushing the baffle 2 from the closed position to the open position is provided. The operation button 3 is disposed on one side surface of the baffle 2 and protrudes and can operate the play plate 2 from the open position to the closed position against the urging force of the coil spring S1 (pushing device); As shown in Fig. t, the operation button 3 is placed in a recess 7 formed in the surface of the casing and protrudes and can be operated in the recess 7. Therefore, since the operation button 3 is formed in a protrusion manner and can be operated in the recess portion 7 (in other words, the operation range is limited to the inside of the recess portion 7), as shown in Fig. 2, the manipulation 3 can be prevented. The surface of the casing protrudes, thereby preventing the steering 3 from interfering with a vehicle driving and other constituent elements of a vehicle. According to this embodiment, since the button 3 is formed in a manner and can be operated in the recess 7, the operation button 3 can be prevented from interfering with the vehicle driving and other constituent elements of the vehicle. 5 ❹ 10 15 ❹ 20 The operating button 3 is configured such that when it is held in a state in which it positions the shutter 2 in the closed position (when it is positioned in a solid line as shown in FIG. 1 In position, it approaches (or can contact) the wall 7a of the recess 7. Therefore, when the shutter 2 is positioned at the closed position, it is difficult to operate the operation knob 3, which prevents the third party from illegally operating the operation button 3 using a tool or the like, whereby the crime prevention effect can be enhanced. A locking mechanism 6 is used to lock the flap 2' held in the closed position to thereby prevent a third person from operating the operating button 3 and thus operate the flap 2 from the closed position to the open position. As previously mentioned, the locking mechanism 6 comprises the fixing device 4 and the locking device 5. These fixing devices 4 and locking devices 5 are respectively disposed on the other side surface 2b side of the baffle 2 (on the upper surface side in FIGS. 3 to 5), and the operation knob 3 and the locking mechanism 6 are disposed in this block. Board 2 is located between the roads. The fixing device 4 is movable into the fixing recess 2ba of the baffle 2 held at the closed position and fixes the baffle 2, and the fixing device 4 is normally pushed toward the baffle 2 by a coil spring S2 (at the Figures 3 to 5 are downwards). Specifically, the fixing device 4 includes a fixed surface 4a and a tapered surface which are respectively formed on the side of the projecting end thereof. When the shutter 2 is positioned at the closed position, as shown in Fig. 3, the fixing surface 4a is fixed to the fixing recess 2ba to prevent the jaw 2 from sliding to the open position. The tapered surface 4b contacts the tapered surface 2bb' of the baffle 2 during the sliding of the baffle 2 from the open position to the closed position to push the fixing device 4 upward, thereby causing the baffle 2 can 11 200940393 Slide to the closed position.

When the locking device 5 thus constructed is placed on the magnetic lock projection portion lab, the fitting holes can be fitted and fixed to the magnet μ which is pushed above the coil spring S1. The magnetic key is used to release the locked state of the plate 2 generated by the locking mechanism 6 (in detail, the fixed state caused by the fixing device 4). 2 moves from the closed position to the open position. For example, the magnetic key yoke is constituted by a portion integrally formed with a grip portion (a portion made of resin) of a start key used in a two-wheeled vehicle. A plurality of magnets 20 m are embedded in the front end of the magnetic key & In a state in which the magnetic key 后 is engaged with the bulging portion 5b of the locking device 5, the magnets m are disposed at positions respectively corresponding to the magnets M; and the magnets m are disposed to The polarities of the magnets m having different polarities on the surface side of the upper surface of the magnets face the polarity of the upper surface side of the magnets. 12 200940393 5 e 10 15 ❹ 20 With this configuration, when the locking device 5 (baffle 2) is locked, when the magnetic key MK is inserted into the embedded portion 5b, due to the magnets and settings The repulsive force generated between the magnets m in the magnetic key cartridge moves downwardly against the urging force of the spiral spring, thereby releasing the locked state of the locking device 5. In this state, when the magnetic key is rotated, the locking device 5 rotates together with the rotation of the magnetic key MK due to its engagement with the embedded portion, and the protruding portion 5a also rotates. Therefore, as shown in Fig. 4, the fixing device 4 can move upward against the urging force of the coil spring S2. Thus, the fixed state generated by the fixing device 4 has been released, and the shutter 2 can be automatically slid to the open position by the closing position due to the urging force of the screw magazine S1. Further, according to this embodiment, as shown in FIGS. 3 to 5, the shutter 2 includes a notch portion 2c having a shape corresponding to the insertion holes 1ba, laa; and, as shown in FIG. 5, when the block When the plate 2 is held in the open position, the notch portion 2c is aligned with the insertion holes 1ba, laa. Therefore, when compared with a baffle formed as a rectangle, the stroke of the baffle 2 from the closed position to the open position can be reduced, so that the overall size of the cylinder lock protector can be further reduced. The operation of the aforementioned cylinder lock protector will be explained below. First, when the shutter 2 is held in the open position, the operator can pinch the operation knob 3 and operate it to thereby slide the shutter 2 against the urging force of the coil spring S1. During this sliding process, since the tapered surface 2bb of the baffle 2 contacts the tapered surface 4b of the fixing device 4, the driving force of the fixing device 4 against the helical spring S2 is moved upward by a cam action, so that 13 200940393 The baffle 2 slides up again' and by the re-sliding of the baffle 2, the fixing device 4 is moved into the fixing recess 2ba to thereby fix the baffle 2. Therefore, the shutter 2 is fixed in the closed position and is locked by the locking mechanism 6, so that a third person can be prevented from illegally opening the keyhole 'V. On the other side, when the shutter 2 is held in the closed position, the operator can insert the magnetic key MK into the fitting portion 5b so that not only the fixed state generated by the magnets can be released, And if the magnetic key mk is rotated in this state, the protruding portion 5a also moves the fixing device 4, thereby releasing the fixed state of the shutter 2. Therefore, the striker 2 is slid to the open position by the pushing force of the coil spring 81. According to the foregoing embodiment, not only is the operation knob 3 disposed on the one side surface 2a of the shutter 2 extending in the sliding direction thereof but also protruded, and since the locking mechanism 6 (the fixing device 4 and the locking device 5) is disposed, The other side surface 2b of the baffle 2, the operating button 3 and the locking mechanism 6 are respectively disposed such that the baffle 2 is located between the 15 thereof, thereby reducing the overall size of the cylinder lock protection device and obtaining the baffle 2 Sliding range. Since the locking mechanism 6 includes a fixing device 4 that can be fixed to the playing board 2 held at the closing position 1 , and a locking device 5 for releasing the fixed state of the playing board 2 by the fixing device 4 Therefore, the force required for the fixing device 4 to fix the standby plate (the driving force of the coil spring S2) and the force required for the locking device 5 to release the fixed state of the jaw plate 2 (the pressure of the 0 ring b) can be They are set separately so that these forces can be set according to their respective appropriate values. Although the cylinder lock protection device of this embodiment has been described herein, & month is not limited thereto and, for example, the recess is not necessarily formed in the housing 14 200940393 and the operation button may be formed such that it can be made Slide on the surface of the housing. In the embodiment, a magnetic lock for fixing the magnet rivers is used as the lock device 5, but instead, other types of lock devices may be used. 5 <Industrial Applicability> The present invention can be effectively applied not only to the above-described type of cylinder lock protection device but also to other types of cylinder lock protection having a different shape from the above-described device or having other functions attached thereto. The apparatus is provided as long as the operation button is provided on one side surface of the shutter extending in the sliding direction thereof and protruded, and a 10 locking mechanism is disposed on the other side surface side of the shutter.
