JP-A-4-230479

  While the bicycle locking device as in Patent Document 1 has the above-described effects, the swinging of the stand is interlocked with the protruding and retracting operation of the locking rod. When the stand is swung down unexpectedly due to vibration due to road irregularities or misoperation, etc., the locking rod may enter and catch between the spokes on the rear wheel, so there is room for improvement mainly from the safety aspect. There is.

  Therefore, in view of the above-described situation, the present invention intends to solve the problem that the motorcycle is unexpectedly locked while the motorcycle is in operation while being configured to be locked when the stand is stood down from a motorcycle such as a bicycle or a motorcycle. The object of the present invention is to provide a highly safe locking device for a two-wheeled vehicle because the locking rod does not enter between the spokes even if the stand swings downward.

  In order to solve the above problems, the locking device for a motorcycle according to the present invention is fixed to the vehicle body of the motorcycle with both ends facing each other so as to have openings in the rim inside the rear wheel of the motorcycle. A ring-shaped casing and a locking bar supported by the casing so as to be able to protrude and retract, and the locking bar is inserted between the spokes of the rear wheel so that the locking bar is interposed between both ends of the casing. A ring lock that prevents rotation of the rear wheel in a crossed state and a rear lock provided on the rear wheel side so as to support the vehicle body in order to make the two-wheeled vehicle self-supporting, so that it does not get in the way. A predetermined swing angle range between two positions of the rear flip-up position that is flipped up backward is swingable around the swing support shaft, and is attached at a position spaced upward from the stand body at the rear flip-up position. A stand provided with an abutting member, a connecting member supported by the vehicle body located below the stand in the rear flip-up position, and supported by the vehicle body located forward and above the connecting member An intermediate support member that is connected to the locking bar of the ring lock, spanned to the rear side of the intermediate support member, and a cord body having the other end connected to the connection member. When the stand is swung from the rear flip-up position to the standing position, an intermediate rocking angle within the predetermined rocking angle range is provided between the connecting member and the intermediate support member of the cable body. Further, the abutting member of the stand abuts from above, the cord body is pulled by the abutting member that swings together with the stand, and the locking bar of the ring lock is driven to enter a locked state. And

According to such a structure, when the operation of getting off the two-wheeled vehicle and standing the stand is performed, the contact member of the stand moves from the upper side of the rope body while pulling, and the ring body is connected to the ring. Since the locking rod of the lock is driven by the cable body, the ring lock is locked in the standing position.
Therefore, since the ring lock is always locked in conjunction with the operation of raising the stand, it is possible to prevent forgetting the locking and to save the trouble of the locking operation.
In addition, since the stand is not swung downward until an intermediate rocking angle within a predetermined rocking angle range between the standing position and the rear flip-up position of the stand, the rope body is not pulled. If the stand suddenly swings downward within an intermediate swing angle during the operation of the two-wheeled vehicle, the cord body will not be pulled, and the locking rod of the ring lock will not be driven. Since it does not enter between the spokes and get caught, safety is increased.

Here, it is preferable that the intermediate swing angle is a swing angle at which the rear wheel is lifted from the ground when the stand is swung from the rear flip-up position to the standing position.
According to such a configuration, the abutting member does not abut on the cable body until the rear wheel is lifted from the ground after the stand is raised, so that the rear wheel is lifted from the ground. Until the cable body is not towed, that is, when the rear wheel of the two-wheeled vehicle is in contact with the ground, the locking rod to which the cable body is connected is not driven, thus improving safety. To do.

Further, it is preferable that when the ring lock is unlocked, the lock body that locks the lock bar is operated in the locked state of the ring lock to move backward, and the retracted position is maintained.
preferable.
According to such a configuration, when the unlocking operation of the ring lock is performed, the lock body is retracted and the retracted position is maintained. Therefore, the ring lock can be easily brought into the unlocked state by setting the stand to the rear flip-up position. Since it can be returned, the operability of the locking device is improved.

Further, the connecting member has a through-hole through which the cable body can be inserted, the cable body is slidable in the insertion direction, and a terminal at the other end of the cable body is through the through-hole. Since it is a magnitude | size which cannot enter a hole, it is preferable when the said rope body is prevented from coming off with respect to the said connection member.
According to such a configuration, the end of the other end portion of the rope body has a size that cannot enter the through hole of the connecting member, and the rope body is prevented from being detached from the connecting member. The terminal of the other end of the cable body is connected to the body while it has a structure that does not interfere with the operation of driving the locking bar by pulling the cable body when the stand contact member comes into contact with the body. Since the cable body is not fixed to the member and can slide through the through hole of the connecting member in the insertion direction, the operation piece connected to the locking rod of the ring lock even in the state where the stand is in the rear flip-up position Can be manually operated and locked, and the cable body can be smoothly and reliably operated without being bent during the locking operation.
Therefore, it is possible to easily deal with parking in a bicycle parking lot of a two-wheeled vehicle that requires parking in a state where the stand is not raised.

  As described above, according to the locking device for a two-wheeled vehicle according to the present invention, (a) when the stand is set up after getting off the two-wheeled vehicle, the ring lock is always locked in conjunction with the operation of setting the stand. It is possible to prevent forgetting the locking and save the trouble of the locking operation. (A) Since the strut is not pulled unless the stand swings downward to the intermediate swing angle, If the stand unexpectedly swings downward within an intermediate swing angle during two-wheeled vehicle operation, the striated body will not be pulled, and the locking rod of the ring lock will not be driven. Since it does not enter and get caught in between, there are significant effects such as increased safety.

It is a waste.
In this specification, the direction of traveling in the state of riding a bicycle B shown as an example of a two-wheeled vehicle in which wheels are arranged in front and rear, such as a bicycle, a power-assisted bicycle, a motorized bicycle or a motorcycle, is defined as the front, Means forward and the front view is the view from the left.

As shown in the front view around the rear wheel C of the bicycle B in FIG. 1, the vehicle body F around the rear wheel C has a seat tube F1, which is a pipe into which a seat post is inserted, an upper end portion of the seat tube F1, and the rear wheel C. The seat stay F2 that is a pipe that connects the axle I and the chain stay F3 that is a pipe that connects the lower end of the seat tube F1 and the axle I of the rear wheel C, and the stand 11 is set to the standing position P1. The vehicle body F is supported by the stand 11, and the bicycle B is self-supporting.
As shown in the front views of FIGS. 1 and 6, the stand 11 jumps backward so as not to obstruct the standing position P <b> 1 standing so as to support the vehicle body F in order to make the bicycle B self-supporting and traveling. The predetermined swing angle range AR between the two positions of the raised rear flip-up position P2 is swung around the swing support shaft H.

Further, the stand 11 has a vertical roller 12 as a contact member by a support piece 11B extending upward from a position separated from the swing support shaft H of the stand main body 11A toward the free end side at the rearward raising position P2 shown in FIG. In other words, the vertical roller 12 is provided at a position spaced upward from the stand main body 11A.
Further, below the stand 11 (stand main body 11A) at the rear flip-up position P2, the connecting member 13 attaches the support member 15 shown in FIG. 1 to a plate that connects the axle I and the swing support shaft H. The vertical roller 14 serving as an intermediate support member supports the support member 16 shown in FIG. 1 on the axle at a position that is supported by the vehicle body F and forward and above the connection member 13 (for example, a rear position of the swing support shaft H). It is supported by the vehicle body F by being attached to a plate connecting I and the swing support shaft H.
Furthermore, the wire 10 which is a flexible cable body has one end portion 10A connected to the locking rod 3 (see FIG. 2) of the ring lock 1 and a middle portion attached to the seat tube F2. The outer cover body 9 is supported by members 9 </ b> A and 9 </ b> B (see FIGS. 7 and 8) and is passed over the rear side of the vertical roller 14, and the other end portion 10 </ b> B is connected to the connecting member 13.

Next, the ring lock (horse-shoe lock) 1 will be described.
As shown in the partial vertical cross section of FIG. 2, the ring lock 1 is attached to the seat tube F2 of the vehicle body F with both ends 2A and 2B facing each other so as to have an opening G inside the rim D of the rear wheel C. It consists of a fixed ring-shaped (horse-shoe-shaped) casing 2 and a locking rod 3 etc. supported by the casing 2 so as to be able to protrude and retract, and the locking rod 3 is spokes E and E of the rear wheel C (see FIG. 1). )) And the rotation of the rear wheel C is prevented with the locking rod 3 extending between the two end portions 2A and 2B of the casing 2.
Since the one end 10A of the wire 10 is connected to the locking bar 3 as described above, the lock 11 is pulled by the wire 10 and locked as described later by setting the stand 11 to the standing position P1 (see FIG. 1). The bar 3 is driven to enter the locked state L, and can also be locked by manually operating the operating piece 4 connected to the locking bar 3 protruding from the slit 2C formed on the upper surface of the casing 2. The key K can be unlocked by inserting it into the keyhole 1A of the main body and turning it.

As shown in the partial longitudinal schematic view of FIG. 3, the end of the tension coil spring S1 is connected to the rear end of the locking bar 3 (the end on the side that does not appear in the opening G). In the free state, the unlocking state UL of the ring lock 1 is set such that the locking bar 3 is retracted so as not to protrude into the opening G.
Further, the lock body 7 is urged toward the locking bar 3 by the compression coil spring S2, and the latch 8 capable of swinging around the swing support shaft 8A is rotated clockwise in FIG. 3 by the torsion coil spring S3, that is, The operation piece 8B at one end approaches the locking bar 3 and the engagement piece 8C at the other end is biased in a direction approaching the lock body 7.
In the unlocked state UL of FIG. 3, the operation piece 4 (see FIG. 2) is manually operated as described above or the wire 10 (see FIG. 2) is operated by setting the stand 11 to the upright position P1. By being pulled, the locking bar 3 is driven and enters the opening G, so that the ring lock 1 is in the locked state L shown in the partial longitudinal schematic view of FIG.

In the locked state L of FIG. 4, the operation piece 8B of the latch 8 is inserted into the first notch (recessed part) 5 of the locking bar 3 and the lock piece 7A of the lock body 7 is inserted into the second notch (recessed part) 6. Then, the locking piece 7A abuts against the abutment surface 6A of the second notch 6 and the locking bar 3 is prevented from moving backward, so that the locked state L is maintained.
In the locked state L of FIG. 4, when the unlocking operation is performed by inserting the key K shown in FIG. 2 into the keyhole 1A of the main body and turning it, the lock body 7 interlocked with the unlocking operation is operated, and a partial longitudinal schematic view of FIG. As shown in FIG. 2, the lock body 7 is retracted against the urging force of the compression coil spring, and the engagement piece 8C of the latch 8 is engaged with the engagement hole 7B of the lock body 7, so that the lock piece 7 is retracted. (Retracted position shown in FIG. 5) is maintained.

Therefore, as will be described later, since the pulling force of the locking bar 3 by the wire 10 is eliminated by setting the stand 11 to the rear flip-up position P2, the tension coil spring S1 is extended in the locked state L in FIG. Since it is biased by the restoring force of the coil spring S1, the locking bar 3 returns to the state shown in FIG. 3 and enters the unlocked state UL.
In this way, in the middle of returning from the locked state L of FIG. 4 to the unlocked state UL of FIG. 3, the operating piece 8B of the latch 8 hits the inclined surface 5A of the first notch 5 and the latch 8 swings, and the latch 8 is engaged. Since the engagement between the piece 8C and the engagement hole 7B of the lock body 7 is lost, the state in which the lock piece 7 is held in the retracted position is released, so the lock piece 7 is attached to the locking bar 3 by the compression coil spring S2. It returns to the state where it was energized.

Next, locking by the operation of the stand 11 will be described.
In the schematic front view of FIG. 6 and the main part enlarged front view of FIG. 7, the vertical roller 12 that is a contact member of the stand 11 is separated from the wire 10, and the stand 11 is When the stand 11 swings to the intermediate swing angle A1 within the predetermined swing angle range AR shown in FIG. 6 when swinging from the rear flip-up position P2 to the standing position P1, the connecting member 13 and the intermediate support member are provided. The vertical roller 12 comes into contact with the wire 10 with the vertical roller 14 from above (see the solid line in FIG. 6).
When the stand 11 is further swung (locking operation swing angle A2) from this state to the standing position P1 of the stand 11 shown in the enlarged front view of the main part in FIG. 10 is pulled, and the locking bar 3 (see FIG. 2) of the ring lock 1 is driven to enter the locked state L.
Here, as shown in FIG. 6, the intermediate swing angle A1 is such that the rear wheel C is at a height J (for example, about 5 mm to 10 mm) from the ground when the stand 11 is swung from the rear flip-up position P2 to the standing position P1. ) Is set to an angle that only floats.

Next, a configuration example of the other end portion 10B of the wire 10 and the connecting member 13 will be described.
9B, the connecting member 13 has a through-hole 13A through which the wire 10 can be inserted, so that the wire 10 can slide through the through-hole 13A in the insertion direction. Since the terminal 10C of the other end portion 10B of the wire 10 is set to a size that cannot enter the through hole 13A, the wire 10 is prevented from coming off from the connecting member 13.
Therefore, as shown in the schematic front view of FIG. 9A, when the operating piece 4 is manually operated while the stand 11 remains at the rearward raising position P2 to bring the ring lock 11 into the locked state L, the wire 10 is connected to the connecting member. As shown in FIGS. 9A and 9B, the terminal 10 </ b> C of the wire 10 moves to a position away from the connecting member 13.

According to the configuration of the locking device for a two-wheeled vehicle according to the embodiment of the present invention as described above, when the operation of getting off the bicycle B and standing the stand 11 is performed, the vertical roller 12 of the stand 11 contacts the wire 10 from above. Since the locking rod 3 of the ring lock 1 to which the wire 10 is coupled is driven by the wire 10 while being pulled while contacting, the ring lock 1 is in the locked state L at the standing position P1.
Therefore, the ring lock 1 is always locked in conjunction with the operation of raising the stand 11, so that it is possible to prevent forgetting the locking and to save the trouble of the locking operation.
In addition, the wire 10 is not pulled unless the stand 11 swings downward to an intermediate swing angle A1 within a predetermined swing angle range AR between the two positions of the stand 11 standing position P1 and the rear flip-up position P2. Therefore, even if the stand 11 is unexpectedly swung downward at an angle within the intermediate swing angle A1 during the operation of the bicycle B, the wire 10 is not pulled, and the locking bar 3 of the ring lock 1 is Since it is not driven, the locking rod 3 does not enter and get caught between the spokes E and E, so that safety is improved.

Further, as shown in FIG. 6, the intermediate swing angle A1 is a swing angle at which the rear wheel C is lifted from the ground when the stand 11 is swung from the rear flip-up position P2 to the standing position P1. Since the vertical roller 12 does not contact the wire 10 until the rear wheel C is lifted from the ground by performing the operation of raising the stand 11, the rear wheel C is lifted from the ground. The wire 10 is not towed until the rear wheel C is reached, that is, when the rear wheel C of the bicycle B is in contact with the ground, the locking rod 3 to which the wire 10 is connected is not driven. Will improve.
Furthermore, as shown in FIG. 5, the locking bar 3 is unlocked in the locked state L of the ring lock 1 by an unlocking operation of the ring lock 1 (for example, an operation of inserting and turning the key K shown in FIG. 2 into the keyhole 1A of the main body). The lock body 7 that locks the lock body is operated and retracted, and the retracted position is held by the latch 8 so that the unlocking operation of the ring lock 1 is performed and the retracted position of the lock body 7 is held. Then, the ring lock 1 can be easily returned to the unlocked state UL by setting the stand 11 to the rear flip-up position P2, so that the operability of the locking device is improved.

9B, the connecting member 13 has a through-hole 13A through which the wire 10 can be inserted, and the wire 10 can slide in the insertion direction through the through-hole 13A. Since the terminal 10 </ b> C of 10 </ b> B has a size that cannot enter the through hole 13 </ b> A, the wire 10 is prevented from coming off with respect to the connecting member 13, so that the vertical roller 12 of the stand 11 contacts the wire 10 and the wire 10 is The terminal 10 </ b> C of the other end 10 </ b> B of the wire 10 is not fixed to the connecting member 13, and the wire 10 is connected to the wire 10, although the structure does not hinder the operation of driving the locking bar 3 by pulling tension. Since the through-hole 13A of the member 13 can be slid in the insertion direction, even when the stand 11 shown in FIG. 9A is in the rear flip-up position P2, the ring lock 1 The operation piece 4 which is connected to the lock bar 3 it is possible to lock manually operated, can operate smoothly and reliably without the wire 10 is flexed during the locking operation.
Therefore, it is possible to easily deal with parking in a parking lot where parking is required in a state where the stand 11 is not raised (backward raising position P2).
