Description

  The present invention relates to a wheel lock device for a motorcycle used to prevent theft of a motorcycle.

  As a device for preventing theft of a motorcycle, a locking device using a wire, a chain, or a U-shaped metal rod is known, but these are relatively simple by a wire cutting tool such as a bolt clipper. It has a drawback that it can be severely disconnected and easily removed illegally by a third party trying to steal. Further, if the constituent wires are made thick in order to make them difficult to cut, there is a problem that the weight increases and becomes bulky, resulting in poor portability and handling.

On the other hand, a wheel lock device for a motorcycle called a disk lock that is extremely compact and excellent in portability and handleability is also known (for example, see Patent Document 1). As shown in FIG. 14, the wheel lock device a is formed by a main body part b and a leg piece part c facing each other through a groove d so that the overall shape thereof is substantially U-shaped. Has a built-in cylinder lock f with a lock pin e that protrudes and retracts into the groove d by a key operation, while the leg piece c is provided with a fitting recess g into which the tip of the lock pin e can be fitted. Yes. Then, as shown in FIGS. 15 and 16, the lock pin e is protruded with the peripheral edge of the disc rotor k attached to the wheel j of the motorcycle h inserted into the groove d, and the lock pin e is The disk rotor k is inserted through the hole m, and the tip is inserted into the fitting recess g on the leg piece c side and locked. As a result, when the motorcycle h is to be started, the wheel lock device a mounted on the disc rotor k abuts against the brake caliper n or the front fork p and the rotation of the wheel j is restricted, so that the locked state is obtained. It has become.

  By the way, in the disk lock type wheel lock device a as described above, a wire cutting tool such as a bolt clipper is used as compared with a locking device using a wire, a chain, or a U-shaped metal rod. Although the removal by cutting is difficult and the anti-theft effect is high, the wheel j and the disc rotor k are separated by removing a plurality of bolts r (see FIG. 16) fixing the disc rotor k to the wheel j. Then, the rotation of the disc rotor k on which the wheel lock device a is mounted is restricted because the wheel lock device a contacts the brake caliper n or the front fork p, but the wheel j itself is in a rotatable state. Therefore, there is a problem in that the motorcycle h may be taken away by being pushed and moved.

  The present invention has been made to solve such conventional problems. In a disk lock type wheel lock device, the rotation of the wheel can be achieved even if the wheel and the disk rotor on which the wheel lock device is mounted are separated. It is an object of the present invention to provide a wheel lock device for a motorcycle that can disable the motor.

  The present invention relates to a wheel lock device for a motorcycle that is detachably mounted on a motorcycle and prevents rotation of the wheel, and a perforated circular shaft support plate that includes either a disc rotor of a disc brake or a sprocket wheel for driving a rear wheel. A fitting hole with a predetermined depth and a locking rod with a predetermined length projecting from the inner surface are disposed at a predetermined interval on the inner surface of the metal block that faces the outer surface of the metal block. The lock body in which the cylinder lock in which the locking pin protrudes and retracts along the radial direction from the inner peripheral surface of the fitting hole by the key operation and the inner surface of the perforated circular shaft support plate are opposed to each other. A locking rod is fixed to the metal plate piece in a penetrating state, and one end side of the locking rod is removably fitted into the fitting hole of the lock body so as to be engaged with the locking pin, and A lock member in which the end side is a wheel lock shaft portion of a predetermined length that can be inserted between the spokes of the wheel of the motorcycle and the insertion hole through which the locking rod can be inserted is formed in a metal plate piece. The lock body and the lock member are opposed to each other with a perforated circular shaft support plate interposed therebetween, and the locking shaft portion of the lock member or the locking rod of the lock body is formed on the perforated circular shaft support plate. The locking shaft portion of the lock member and the locking rod of the lock body are respectively inserted into different hole portions formed in the perforated circular shaft support plate, and the locking shaft portion is inserted into the lock body. A wheel lock device for a motorcycle, which is locked by being fitted into a fitting hole and engaged with a locking pin, and a locking rod is inserted into an insertion hole of a metal plate piece.

  Here, although hard metals such as stainless steel, alloy steel, and special alloy tool steel can be suitably used for the material of the locking rod and the locking rod, there is an opportunity for the wheel lock device for motorcycles to be used outdoors. Since there are many, stainless steel with especially excellent corrosion resistance is preferable. In addition, by forming a locking rod with a diameter of about 10 to 18 mm and a locking rod with a diameter of about 18 to 25 mm using such a steel material, it is easy to use not only a wire clip cutting tool such as a bolt clipper but also a saw. It is impossible to cut it.

  Moreover, in the wheel lock device for a motorcycle, a configuration is proposed in which the locking rod has a predetermined length inserted between spokes of the wheel of the motorcycle in the locked state.

  Furthermore, the present invention provides a wheel lock device for a motorcycle that is detachably mounted on a motorcycle and prevents the rotation of the wheel, and a perforated circular shaft comprising either a disc rotor of a disc brake or a sprocket wheel for driving a rear wheel. A fitting hole having a predetermined depth is opened on the inner side surface of the metal block that faces the outer side surface of the support plate, and the inside of the fitting hole is radially extended from the inner circumferential surface by a key operation. The lock rod is fixed in a penetrating state to the lock body in which the cylinder lock in which the lock pin protrudes and retracts is built, and the metal plate piece facing the inner surface of the perforated circular shaft support plate, and one end of the lock rod The locking shaft portion that is detachably fitted into the fitting hole of the lock body and engaged with the locking pin, and the other end side is a predetermined length that can be inserted between the spokes of the motorcycle wheel. And a locking member as a wheel lock shaft part, with a perforated circular shaft support plate in between, the lock body and the lock member are arranged to face each other, and the locking shaft part of the lock member is a perforated circular shaft support. A wheel lock for a motorcycle, which is locked by being inserted through a hole formed in a plate, and engaging the locking shaft with a fitting hole of a lock body and engaging with a locking pin. Device.

  Here, as described above, hard metal such as stainless steel, alloy steel, and special alloy tool steel can be suitably used as the material of the locking rod, but the opportunity to use the wheel lock device for motorcycles outdoors is also possible. Therefore, stainless steel having particularly excellent corrosion resistance is preferable. Further, by forming the locking rod with such a steel material with a diameter of about 18 to 25 mm, not only a wire cutting tool such as a bolt clipper but also a saw cannot be easily cut.

  As described above, according to the present invention, the inner surface of the metal block that faces the outer surface of the perforated circular shaft support plate made of either the disk rotor of the disk brake or the sprocket wheel for driving the rear wheel is provided on the inner surface of the metal block. A fitting hole having a depth and a locking rod having a predetermined length protruding from the inner surface are disposed at a predetermined interval, and the key hole is used to radially enter the fitting hole from the inner peripheral surface thereof. A lock rod is fixed in a penetrating state to a lock body in which a cylinder lock along which a locking pin protrudes and retracts and a metal plate piece facing the inner surface of a perforated circular shaft support plate is inserted, One end side is slidably fitted in the fitting hole of the lock body so as to be a locking shaft portion engaged with the locking pin, and the other end side is a predetermined length that can be inserted between spokes of a wheel of a motorcycle. Wheel lock And a lock member in which a through hole into which the locking rod can be inserted is formed in a metal plate piece, with a perforated circular shaft support plate interposed between the lock body and the lock member And the locking shaft portion of the lock member or the locking rod of the lock body is inserted into the hole formed in the perforated circular shaft support plate, or the locking shaft portion of the lock member and the lock body are locked. The rod is inserted into different holes formed in the perforated circular shaft support plate, the locking shaft is fitted into the fitting hole of the lock body and engaged with the locking pin, and the locking rod is made of metal. Since it is a wheel lock device for a motorcycle that is locked by being inserted through the insertion hole of the plate-made plate piece, the lock body and the lock member are detachably mounted on the perforated circular shaft support plate in the locked state. Along with the metal plate of the lock member State the wheel lock shaft portion of the locking rod projecting is inserted between the wheels of the motorcycle spokes from is obtained. As a result, a motorcycle that steals a motorcycle can separate the perforated circular shaft support plate on which the wheel lock device for the motorcycle is attached and the wheel, and then push the motorcycle to move it. The lock body of the locking rod inserted between them abuts the spokes of the wheel and the lock body mounted on the perforated circular shaft support plate is attached to the brake caliper, front fork or near the wheel as the wheel rotates. Since it abuts on the vehicle body frame, further rotation of the wheels is restricted, and the motorcycle can be made immovable.

  Further, in the configuration in which the locking rod has a predetermined length that is inserted between the spokes of the wheel of the motorcycle in the locked state, in addition to the wheel lock shaft portion of the locking rod, the wheel is also used by the locking rod. Can be controlled. And although the locking rod and the locking rod are difficult to cut depending on the selection of the material and thickness, the two can make the cutting even more difficult.

  In addition, as described above, the present invention is provided on the inner surface of the metal block that faces the outer surface of the perforated circular shaft support plate made of either the disk rotor of the disk brake or the sprocket wheel for driving the rear wheel. A lock body having a built-in cylinder lock in which a locking hole having a predetermined depth is opened and a locking pin protrudes and retracts along the radial direction from the inner peripheral surface of the fitting hole by a key operation; A locking rod is fixed in a penetrating state to a metal plate piece facing the inner surface of the circular shaft support plate, and one end side of the locking rod is removably fitted into the fitting hole of the lock body, and A locking shaft portion that engages with the locking pin, and a locking member that has a wheel lock shaft portion of a predetermined length that can be inserted between the spokes of the motorcycle wheel on the other end side, and a perforated circular shaft Between the support plates Then, the lock body and the lock member are arranged to face each other, the lock shaft portion of the lock member is inserted into the hole formed in the perforated circular shaft support plate, and the lock shaft portion is fitted into the fitting hole of the lock body. Since this is a wheel lock device for a motorcycle that is locked by engaging with a locking pin, in the locked state, the lock body and the lock member are detached from the perforated circular shaft support plate in the same manner as described above. The wheel lock shaft portion of the locking rod protruding from the metal plate piece of the lock member is inserted between the spokes of the motorcycle wheel. As a result, a motorcycle that steals a motorcycle can separate the perforated circular shaft support plate on which the wheel lock device for the motorcycle is attached and the wheel, and then push the motorcycle to move it. The lock body of the locking rod inserted between them abuts the spokes of the wheel and the lock body mounted on the perforated circular shaft support plate is attached to the brake caliper, front fork or near the wheel as the wheel rotates. Since it abuts on the vehicle body frame, further rotation of the wheels is restricted, and the motorcycle can be made immovable.

  Further, in the configuration of the present invention, since the locking rod of the lock body in the above-described device and the insertion hole of the metal plate piece through which the locking rod is inserted are unnecessary, the structure can be simplified. There is an advantage that the whole can be reduced in size and weight.

  A first embodiment of a wheel lock device for a motorcycle according to the present invention (hereinafter simply referred to as “wheel lock device”) will be described with reference to FIGS.

  As shown in FIG. 1, the wheel lock device 1 </ b> A according to the first embodiment includes a lock body 2 and a lock member 3 formed separately from the lock body 2.

  The lock body 2 includes a metal block 4 formed in a rectangular parallelepiped shape. The metal block 4 has a height of about 85 to 100 mm, a width of about 50 mm, and a depth of 25 to 30 mm. Is set to about. The metal block 4 may be made of a hard metal such as stainless steel, alloy steel, or special alloy tool steel. In order to reduce the weight, aluminum alloy steel having a predetermined hardness can be used.

  As shown in FIGS. 2 and 3, the metal block 4 has a predetermined depth at a position close to the upper portion of the inner side surface 5 that faces the outer side surface 26 of the perforated circular shaft support plate 20 described later. The fitting hole 6 is opened. The diameter of the fitting hole 6 is slightly larger than the diameter of the locking shaft portion 14 of the locking rod 13 to be described later, so that the locking shaft portion 14 can be inserted and removed. A locking rod 7 projects from the inner surface 5 of the metal block 4 at a position closer to the lower part at a predetermined interval (about 45 to 55 mm) from the fitting hole 6. The locking rod 7 is made of a hard metal such as stainless steel, alloy steel, special alloy tool steel, etc. as a material, and has a diameter of about 10 to 18 mm that is difficult to cut. By being press-fitted into the mounting hole 8 formed so as not to be escaped, it protrudes from the inner surface 5 to a length of about 25 mm.

  In the metal block 4, a cylinder lock 9 is built in a position near the lower portion of the fitting hole 6 so as to be parallel to the fitting hole 6. The cylinder lock 9 includes a locking pin 10 that protrudes and protrudes in the radial direction from the inner peripheral surface in the fitting hole 6, and a key hole 11 opened on the outer surface side of the metal block 4 (see FIG. 1). The locking / unlocking state of the locking pin 10 is controlled by a turning operation of a key (not shown) inserted into the locking pin 10. Here, the locking pin 10 is normally held in a state of advancing into the fitting hole 6 via a spring bias, and descends toward the inner surface 5 of the metal block 4 at the upper end of the locking pin 10. A pressure-inclined slope 11 that is inclined with a gradient is formed. As a result, when a tapered surface 15 formed at the distal end of the locking shaft portion 14 of the locking rod 13 to be described later comes into contact with the pressed inclined surface 11, a downward pressing force is generated, and the locking pin 10 resists spring bias. While moving backward, when the pressing force on the pressure-inclined slope 11 disappears, the advancing state is restored again via the spring bias. Further, the locking pin 10 can be held at the unlocking position where it is retracted from the fitting hole 6 only by the unlocking operation with the key.

  On the other hand, the lock member 3 includes a metal plate piece 12 that faces an inner surface 27 of a perforated circular shaft support plate 20 described later. The metal plate piece 12 is formed in a rectangular shape, and has a height dimension of about 85 to 100 mm, a width dimension of about 12 mm, and a depth dimension of about 25 to 30 mm. The metal plate piece 12 may be made of a hard metal such as stainless steel, alloy steel, or special alloy tool steel.

  A locking rod 13 is fixed to the metal plate piece 12 in a penetrating state at a position closer to the upper portion corresponding to the fitting hole 6 of the metal block 4. The lock rod 13 is made of a hard metal such as stainless steel, alloy steel, special alloy tool steel, etc., and its diameter is set to a thickness that is difficult to cut such as about 18 to 25 mm. Then, one end side of the locking rod 13 is a locking shaft portion 14 that is removably fitted into the fitting hole 6. The locking shaft portion 14 is formed with a tapered surface 15 whose diameter is reduced in a tapered shape at the tip thereof. When the locking shaft 15 is fitted into the fitting hole 6, the tapered surface 15 is pressed against the pressure-inclined slope 11 of the locking pin 10. It is possible to generate a pressing force that causes the locking pin 10 to retreat downward. Further, an engagement hole 16 is opened on the lower surface of the locking shaft portion 14 at a position corresponding to the locking pin 10 in a state where the locking shaft portion 14 is fitted to the back of the fitting hole 6. When the engagement hole 16 enters the position of the locking pin 10 as the locking shaft portion 14 is inserted into the fitting hole 6, the retracted locking pin 10 advances through a spring bias, The engagement hole 16 is engaged. Thereby, the lock | rock shaft part 14 is hold | maintained so that it cannot escape. Further, as shown in FIG. 3, a perforated circular shape is formed between the metal plate piece 12 and the inner side surface 5 of the metal block 4 with the locking shaft portion 14 being held so as not to escape. A gap 17 having a predetermined width (about 8 mm) in which the shaft support plate 20 can be inserted is formed.

  Further, the other end side of the locking rod 13 is a wheel lock shaft portion 18. The wheel lock shaft portion 18 is set to have a length of about 120 to 160 mm so as to be inserted between the spokes 33 of the wheels 22 of the motorcycle 21 (see FIG. 4).

  Further, the metal plate piece 12 corresponds to the locking rod 7 of the metal block 4 in a state where the locking shaft portion 14 is fitted in the fitting hole 6 of the metal block 4 (see FIG. 3). An insertion hole 19 through which the locking rod 7 can be inserted is formed at a position closer to the lower part.

  As shown in FIG. 4, the above-described perforated circular shaft support plate 20 includes a disc brake 23 mounted on each wheel 22 on the front and rear sides of the motorcycle 21 or a rear wheel mounted on the rear wheel 22. The drive sprocket wheel 24 includes a plurality of holes 25 through which the locking shaft 7 of the locking rod 7 or the locking rod 13 can be inserted. The outer surface 26 of the perforated circular shaft support plate 20 refers to the side surface located on the outer side of the motorcycle 21, and the inner surface 27 of the perforated circular shaft support plate 20 refers to the spokes of the wheels 22. The side located on the 33 side is indicated.

Next, the usage method and operation of the wheel lock device 1A will be described.

  As shown in FIG. 5, in order to mount the wheel locking device 1A to the disc rotor 23, as shown in FIG. 2, the perforated circular shaft support plate 20 comprising the disc rotor 23 is interposed between the lock body 2 and the disc rotor 23. As shown in FIG. 3, the locking rod 7 of the lock main body 2 is inserted into the hole portion 25 formed in the perforated circular shaft support plate 20 and the lock member 3 is locked. While the shaft portion 14 is fitted to the fitting hole 6 of the lock body 2 from the outer peripheral side of the perforated circular shaft support plate 20 and the engagement hole 16 of the locking shaft portion 14 is engaged with the internal locking pin 10, The locking rod 7 protruding from the hole 25 toward the inner surface 27 side of the perforated circular shaft support plate 20 is inserted into the insertion hole 19 of the lock member 3.

  As a result, the locking shaft portion 14 cannot be removed from the fitting hole 6 of the lock body 2 through the engagement between the engagement hole 16 and the locking pin 10, and the locking rod 7 is removed from the insertion hole 19 of the lock member 3. The lock body 2 and the lock member 3 are mounted on the perforated circular shaft support plate 20 so as not to be detachable and protrude from the metal plate piece 12 of the lock member 3 as shown in FIG. The locked state in which the wheel lock shaft portion 18 is inserted between the spokes 33 of the wheel 22 is obtained.

  Then, in this locked state, the one that attempts to steal the motorcycle 21 removes the bolt 31, and after separating the perforated circular shaft support plate 20 to which the wheel locking device 1A is attached and the wheel 22, Even if the motorcycle 21 is pushed and moved, the wheel lock shaft portion 18 of the locking rod 13 inserted between the spokes 33 of the wheel 22 contacts the spoke 33 of the wheel 22 and is mounted on the perforated circular shaft support plate 20. Since the lock body 2 is brought into contact with the brake caliper 28 (see FIG. 5) and the front fork 29 as the wheel 22 rotates, the further rotation of the wheel 22 is restricted and the motorcycle 21 cannot be moved. can do. Thereby, it is possible to reliably prevent the motorcycle 21 from being stolen by a technique that allows the wheel 22 to rotate by separating the perforated circular shaft support plate 20 and the wheel 22.
