    MODES FOR CARRYING OUT THE INVENTION
  • Embodiments of the present invention are explained below by reference to the attached drawings.
    • FIRST EMBODIMENT
  • A first embodiment of the present invention is explained by reference to FIG. 1 to FIG. 8; first, in FIG. 1, a centralized unlocking operation device 16 is disposed on a vehicle body cover 15 for a vehicle, for example, a two-wheeled motor vehicle.
  • Referring in addition to FIG. 2 and FIG. 3, the centralized unlocking operation device 16 includes a main switch 17 and an opening/closing body remote operation part 18 disposed on one side of the main switch 17.
  • The main switch 17 includes a cylinder lock 19 that is operated by means of a mechanical key, and an ignition switch 20 that is connectedly provided with the cylinder lock 19 so that the switching mode of the ignition switch 20 is switched by operation of the cylinder lock 19, the cylinder lock 19 being capable of not only switching the switching mode of the ignition switch 20 but also of switching between a locked state and an unlocked state of the steering.
  • The cylinder lock 19 includes a cylinder body 21 fixed to a vehicle body frame, an inner cylinder 23 having a key hole 22 and being pivotably housed in the cylinder body 21, and a plurality of tumblers 24 disposed on the inner cylinder 23 so as to release engagement with the cylinder body 21 in response to a mechanical key being inserted into the key hole 22.
  • A protecting device 25 is connectedly provided with one end part, on the side opposite to the ignition switch 20, of the cylinder body 21. This protecting device 25 includes a casing 26 covering said one end part of the cylinder body 21, a magnet lock 27 disposed in the casing 26, and a shutter plate 28 housed within the casing 26.
  • Referring in addition to FIG. 4, the casing 26 is formed from a case member 29 that is made of a non-magnetic material and fixedly disposed by being secured to the cylinder body 21 with a bolt, and a cover member 30 that is made of a synthetic resin and is mounted on the case member 29 so as to cover the case member 29 from the side opposite to the cylinder body 21.
  • The cover member 30 is formed so as to have a side wall portion 30a covering part of the outer periphery of the case member 29 from the outside, and the cover member 30 is resiliently engaged with the case member 29 by means of a plurality of resilient engagement parts 34 formed by engaging engagement projections 33 provided at a plurality of locations of the case member 29 with a plurality of engagement holes 32 formed in the side wall portion 30a.
  • The case member 29 and the cover member 30 are provided with insertion holes 35 and 36 that enable a mechanical key to be inserted into the key hole 22 of the cylinder lock 19.
  • Referring in addition to FIG. 5 to FIG. 7, housed within the casing 26 is a shutter plate 28 that can slide between a closed position (position of FIG. 5 and FIG. 6) in which the key hole 22 is closed by blocking between the insertion holes 35 and 36 and an open position (position of FIG. 7) in which insertion of the mechanical key into the key hole 22 via the insertion holes 35 and 36 is enabled by opening the insertion holes 35 and 36 and the key hole 22.
  • This sliding of the shutter plate 28 is allowed by fitting a magnet key into a fitting recess 39 of the magnet lock 27 disposed on the casing 26, the magnet lock 27 being equipped with a rotor 40 pivotably supported by the case member 29 of the casing 26, and the fitting recess 39, which has an irregular polygonal shape, being provided in the rotor 40.
  • Referring to FIG. 4, integrally and projectingly provided on the case member 29 of the casing 26 is a circular cross-section supporting projection portion 29a projecting toward the cover member 30 side, and provided in a portion of the cover member 30 corresponding to the supporting projection portion 29a is a circular opening 41. The rotor 40 is formed into a substantially cylindrical shape from a non-magnetic material and is pivotably supported by the supporting projection portion 29a, an O ring 42 is disposed between a base part of the supporting projection portion 29a and the rotor 40, and the outer end of the rotor 40 is disposed so as to face the opening 41.
  • A plurality of, for example three, pins 43, made of magnets, are slidably fitted into the extremity of the supporting projection portion 29a so as to be capable of moving between a position in which they engage with the rotor 40 and a position in which the engagement is released, and each pin 43 is resiliently urged toward the side on which it engages with the rotor 40 by means of an individually corresponding spring 44.
  • In such a magnet lock 27, fitting a legitimate magnet key into the fitting recess 39 of the rotor 40 enables the pin 43 to move toward the side on which engagement with the rotor 40 is released against the resilient urging force of the spring 44, thereby allowing the rotor 40 to pivot.
  • The shutter plate 28 housed within the casing 26 moves linearly between the closed position and the open position, and the rotor 40 is linked to the shutter plate 28 such that pivoting of the rotor 40 and linear movement of the shutter plate 28 are coupled. In order to link the rotor 40 and the shutter plate 28, in this embodiment, a linking arm 40a extending toward one end of the shutter plate 28 is provided integrally with the outer periphery of the rotor 40, and a linking shaft 45 provided at the extremity of the linking arm 40a is inserted through a linking hole 46 provided in a lower end part of the shutter plate 28.
  • A protector 47 that is made of metal and covers the shutter plate 28 is housed within the casing 26, and this protector 47 is formed into a flat plate shape so as to be present between the cover member 30 and the shutter plate 28. A projecting wall portion 47a that extends substantially parallel to the vertical direction of movement of the shutter plate 28 is integrally and connectedly provided at right angles on one side part of the protector 47, and circular swaging holes 48, 49, and 50 are formed at a plurality of locations, for example three locations, of the protector 47. On the other hand, a housing recess 51 in which the projecting wall portion 46a is housed is formed in the cover member 30, and swaging projections 52, 53, and 54 are provided integrally with the case member 29, the swaging projections 52, 53, and 54 being engaged with the protector 47 by being deformed by swaging in a state in which they are individually fitted into the swaging holes 48 to 50. That is, the protector 47 is fixed to the case member 29 by swaging.
  • Formed integrally with the protector 47 are ribs, for example two ribs 47b and 47c, in sliding contact with the shutter plate 28 so as to extend in the vertical direction. The first rib 47b is formed integrally with the other side part of the protector 47 on the side opposite to the projecting wall portion 47a, and the second rib 47c is formed integrally with the protector 47 so as to be disposed between the insertion hole 36 and the projecting wall portion 47a.
  • Formed integrally with the case member 29 are first and second guide walls 29b and 29c guiding vertical movement of the shutter plate 28 so as to extend in parallel with vertical movement of the shutter plate 28.
  • The shutter plate 28 has a protruding portion 28a protruding sideways from the protector 47 on the side opposite to the projecting wall portion 47a, and a shaft-shaped handle 55 projectingly provided in a lower end part of the protruding portion 28a extends through an elongated hole 56 provided in the cover member 30 so as to extend lengthwise in the vertical direction and projects outside the cover member 30. When the magnet lock 27 is unlocked, the shutter plate 28 can be operated so as to slide between the closed position and the open position by gripping the handle 55.
  • One elastic member 57 is disposed within the casing 26, the elastic member 57 imparting a restraining feel to pivoting of the rotor 40 while carrying out positioning at the closed position thereof, and suppresses rattling of the shutter plate 28 at the open position.
  • This elastic member 57 is formed from a plate spring so as to integrally have a first abutment portion 57a that abuts resiliently against the shutter plate 28 at the open position, a second abutment portion 57b that abuts resiliently against the rotor 40 when the shutter plate 28 is at the closed position and imparts a restraining feel to the pivoting of the rotor 40 while carrying out positioning of the rotor 40, and a linking portion 57c that links the first and second abutment portions 57a and 57b.
  • In the case member 29, the swaging projection 54 disposed between the projecting wall portion 47a and the insertion hole 36 projects from a boss 58 that has a substantially rectangular shaped form and is provided integrally with the case member 29, the linking portion 57c of the elastic member 57 has a substantially U-shaped form so as to be fitted onto the boss 58 from the side opposite to the projecting wall portion 47a, and the first and second abutment portions 57a and 57b are integrally and connectedly provided at opposite ends of the linking portion 57c.
  • The first abutment portion 57a has an extremity portion 57aa rounded into an arc shape, and the extremity portion 57aa abuts resiliently against the shutter plate 28 at the closed position shown in FIG. 5 and FIG. 6, thus suppressing rattling of the shutter plate 28.
  • Furthermore, a recess 59 is formed at one position of the outer periphery of the rotor 40. On the other hand, the second abutment portion 57b has an extremity portion 57ba rounded into an arc shape, and as shown in FIG. 5 and FIG. 6 the extremity portion 57ba is resiliently fitted into the recess 59 of the rotor in a state in which the shutter plate 28 is at the closed position shown in FIG. 5 and FIG. 6 and carries out positioning of the rotor 40 in a state in which the shutter plate 28 is at the closed position. Furthermore, when the rotor 40 pivots in order to slide the shutter plate 28 from the closed position to the open position, due to the extremity portion 57ba of the second abutment portion 57b being fitted into the recess 40, a resilient force from the second abutment portion 57b acts on the rotor 40 against pivoting of the rotor 40, and since it is necessary to pivot the rotor 40 by overcoming the resilient force, this produces a restraining feel.
  • A rear face support plate 60 is fixed, by swaging in a state in which it is engaged with a predetermined position of the case member 29, on a face of the case member 29 of the casing 26 that faces the cylinder body 21 side, a cam member 61 relatively non-pivotably linked to the inner cylinder 23 is housed between the rear face support plate 60 and the case member 29, and an insertion hole 62 corresponding to the key hole 22 is also provided in the cam member 61.
  • Slidably supported on the cam member 61 is a lid member 63 that can move between an open position in which the insertion hole 62 is opened and a closed position in which the insertion hole 62 is closed. This lid member 63 is urged toward the closed position side by means of a pair of springs 64 provided in a compressed state between itself and the cam member 61 (see FIG. 4).
  • Referring in addition to FIG. 8, the opening/closing body remote operation part 18 disposed on one side of the main switch 17 enables a locked state of an opening/closing body disposed at a position separated from the cylinder lock 19, for example a riding seat that can be opened and closed, to be released, and includes a support case 67 mounted on a pair of mounting arm portions 29d and 29d provided on the case member 29 by means of bolts 66 and 66 and an operation element 68 pivotably supported on the support case 67 so as to make part thereof project outward from the support case 67.
  • The support case 67 is formed from a first case member 69 disposed on the casing 26 side of the protecting device 25, a second case member 70 engaged with the first case member 69 while holding the first case member 69 between the second case member 70 and the casing 26, and a third case member 71 engaged with the first and second case members 69 and 70, the second case member 70 being secured to the mounting arm portions 29d and 29d of the case member 29.
  • At least one of the plurality of resilient engagement parts 34 between the cover member 30 and the case member 29, one resilient engagement part 34 in this embodiment, is disposed at a position where the resilient engagement part 34 is covered by the first case member 69 of the support case 67 of the opening/closing body remote operation part 18, and the support case 67 of the opening/closing body remote operation part 18 is mounted on the case member 29 so as to abut against an outer face of the cover member 30.
  • A design member 72 is adhered to the outer face of the cover member 30, the design member 72 displaying the operating position for a mechanical key to be inserted into the key hole 22, the direction of operation of the magnet key in the magnet lock 27, etc. In order to make a design face 72a on the surface of the design member 72 match a design face 67a around the operation element 68 of the surface of the support case 67 of the opening/closing body remote operation part 18, positioning projections 73 and 73 are projectingly provided at two locations of a face of the cover member 30 facing the opening/closing body remote operation part 18 side, and positioning holes 74 and 74 into which the positioning projections 73 and 73 are fitted are formed in an upper end part of the support case 67 of the opening/closing body remote operation part 18. That is, positioning parts 75 and 75 formed from the positioning projection 73 and the positioning hole 74 are provided between the cover member 30 and the support case 67 of the opening/closing body remote operation part 18.
  • As shown in FIG. 2, the operation element 68 is pivotably supported by a support shaft 76 provided between the first and second case members 69 and 70, and pivoting this operation element 68 releases the locked state of the riding seat.
  • A restricting member 77 is provided between the cam member 61 that pivots in response to pivoting of the main switch 17 and the opening/closing body remote operation part 18 such that one end of the restricting member 77 abuts against the outer periphery of the cam member 61, the restricting member 77 being capable of changing positions between an operation-allowed position in which operation of the operation element 68 is allowed according to the pivoting position of the cam member 61 and an operation-restricted position in which it engages with the operation element 68 so as to restrict operation of the operation element 68. The restricting member 77 is urged into sliding contact with the outer periphery of the cam member 61 by means of a spring 78 disposed between the restricting member 77 and the case member 29 (see FIG. 4). Furthermore, as shown in FIG. 2, the operation element 68 is provided with an engagement hole 79 that an end part, on the side opposite to the cam member 61, of the restricting member 77 can be inserted through and engage with.
  • The operation of the first embodiment is now explained. Since the magnet lock 27 is disposed in the casing 26 formed from the case member 29 fixedly disposed so as to cover one end part of the cylinder lock 19 and the cover member 30 covering the case member 29 from the side opposite to the cylinder lock 19, the shutter plate 28 operating when the magnet lock 27 is unlocked between the closed position in which it closes the key hole 22 of the cylinder lock 19 and the open position is housed in the casing 26, and the cover member 30 is made of a synthetic resin, it is possible to lighten the weight of the protecting device 25. Moreover, since the protector 47 formed into a flat plate shape from a metal so as to be present between the cover member 30 and the shutter plate 28 is fixed to the case member 29 so as to cover the shutter plate 28, it is possible to enhance the theft resistance.
  • Furthermore, since the protector 47 is fixed to the case member 29 by swaging, it is difficult to remove the protector 47 from the case member 29 even when the cover member 30 is detached from the case member 29, and it becomes possible to reliably fix the protector 47 to the case member 29.
  • Moreover, since the first and second ribs 47b and 47c in sliding contact with the shutter plate 28 are formed integrally with the protector 47, it is possible to reduce the sliding resistance of the shutter plate 28 and enhance the sliding properties.
  • Furthermore, since the cover member 30 resiliently engages with the case member 29 at a plurality of locations, and the opening/closing body remote operation part 18 enabling the locked state of the opening/closing body disposed at a position separated from the cylinder lock 19 to be released is mounted on the case member 29 so as to abut against the outer face of the cover member 30 while covering at least one of the resilient engagement parts 34 at the plurality of locations, it is possible by means of the opening/closing body remote operation part 18 to prevent the engaged state of at least one resilient engagement part 34 from being released, and it is possible to simply form a structure that prevents the cover member 30 from becoming detached from the case member 29.
  • Moreover, since the two positioning parts 75 for matching the design faces 72a and 67a on the outer faces of cover member 30 and the opening/closing body remote operation part 18 are provided between the cover member 30 and the opening/closing body remote operation part 18, it is possible to prevent displacement of the design faces 72a and 67a.
  • Furthermore, since the protecting device 25 includes the elastic member 57, which integrally has the first abutment portion 57a resiliently abutting against the shutter plate 28 at the open position and the second abutment portion 57b resiliently abutting against the rotor 40 when the shutter plate 28 is at the closed position and imparting a restraining feel to pivoting of the rotor 40 while carrying out positioning of the rotor 40, it is possible by means of one elastic member 57 to prevent the shutter plate 28 at the open position from rattling and to impart a restraining feel to pivoting of the rotor 40 while carrying out positioning of the rotor 40 when the shutter plate 28 is at the closed position, thus enabling the number of components to be reduced.
  • Moreover, since the elastic member 57 is a plate spring, it is possible to easily form the elastic member 57 having the first and second abutment portions 57a and 57b.
    • SECOND EMBODIMENT
  • A second embodiment of the present invention is explained by reference to FIG. 9 to FIG. 11; parts corresponding to those of the first embodiment are denoted by the same reference numerals and symbols and only illustrated, detailed explanation thereof being omitted.
  • A magnet lock 79 has a rotor 80 provided with an irregular polygonal fitting recess 39, and this rotor 80 has formed integrally therewith a shutter plate 81 that pivots together with the rotor 80 between a closed position (position in FIG. 9 and FIG. 10) and an open position (position in FIG. 11).
  • A protector 82, made of metal, covering the shutter plate 81 is formed into a flat plate shape so as to be present between a cover member (not illustrated) and the shutter plate 81. Circular swaging holes 83 and 84 are formed at two locations of the shutter plate 81, and swaging projections 85 and 86 are provided integrally with a case member 29, the swaging projections 85 and 86 being deformed by swaging and engaged with the protector 82 in a state in which they are individually fitted into the swaging holes 83 and 84. That is, the protector 82 is fixed to the case member 29 by swaging.
  • Ribs in sliding contact with the shutter plate 81, for example two first and second ribs 82a and 82b, are formed integrally with the protector 82. Furthermore, provided on the rotor 80 is a shaft-shaped handle 87 disposed at a position displaced from its pivoting center, the handle 87 projecting outside the cover member.
  • An elastic member 88 that imparts a restraining feel to pivoting of the rotor 80 and suppresses rattling of the shutter plate 81 is fitted to the case member 29.
  • This elastic member 88 is formed from a plate spring and has an abutment portion 88a that abuts resiliently against the outer periphery of the shutter plate 81 partway through pivoting of the shutter plate 81 from the closed position to the open position, and the extremity of the abutment portion 88a engages with a recess 89 provided on the outer periphery of the shutter plate 81 in a state in which the shutter plate 81 is at the open position.
  • In accordance with this second embodiment also, it is possible to lighten the weight and enhance the theft resistance, the protector 82 can be reliably fixed to the case member 29, and the sliding resistance for the shutter plate 81 can be made small to thus enhance the sliding properties.
  • Embodiments of the present invention are explained above, but the present invention is not limited to the embodiments and may be modified in a variety of ways as long as the modifications do not depart from the spirit and scope thereof.
