This operation can be performed arbitrarily by the operator, so if the operator makes a mistake and operates the pedals and releases the handlebars before the two-wheeled vehicle is fixed, there is a possibility that the two-wheeled vehicle will roll over, and the parking operation may be delayed. This required a certain degree of skill and care.

JP2009-262794A

The problem to be solved is the need for skill in warehousing operations.

First, the direction in which a vehicle approaches the bicycle parking device of the present invention is defined as forward, the state in which the vehicle is parked on the bicycle parking device is defined as entering the vehicle, and the state in which the vehicle leaves the vehicle is defined as leaving the vehicle.
The present invention provides a foundation member fixed to a floor surface that serves as a path for a two-wheeled vehicle, and a base member that swings from an inclined position where the front part of a front wheel of the two-wheeled vehicle comes into contact with the vehicle during the vehicle storage process to a storage position of the two-wheeled vehicle. a wheel front fixing member that is connected to the base member by a link joint so as to fix the front part of the front wheel in the traveling direction and in the left-right direction at the storage position; In the storage process of a two-wheeled vehicle, the front wheel passes over the top thereof and is swung by a link so that it rises from a fallen position on the foundation member in conjunction with the swinging of the wheel front fixing member to the storage position. A wheel rear support member that is movably coupled and presses the rear part of the front wheel, and a connecting member that connects the wheel front fixing member and the wheel rear support member so as to be relatively rotatable by a link joint to perform the interlocking. The length Xf of the link side formed by the wheel front fixing member between the base member and the connection member is longer than the length Xr of the link side formed by the wheel rear support member, and The distance from the link node between the wheel front fixing member and the foundation member at the storage position to the contact point of the wheel front fixing member with the front wheel is Wf, and the wheel at the storage position Let Wr be the distance from the link node between the rear support member and the base member to the point where the wheel rear support member presses the front wheel, (Xf/Wf)>(Xr/Wr), and When the support member tries to rise from the base member due to the rotational moment caused by the force acting from the connection member, the wheel rear support member rises against the moment arm and presses the rear part of the front wheel with the rotational moment caused by the force applied from the connection member. The moment arm was set to be large when the

The means for driving the wheel rear support member and fixing and releasing the rocking motion is an actuator that uses external power, or a method that uses the forward force of the front wheels as a driving source instead of an actuator. a wheel front fixing member that is engaged to be swingable about a horizontal axis perpendicular to the base member; and a wheel rear support member that is also engaged to be swingable about a horizontal axis that is orthogonal to the base member. , the link side is a transmission means that is swingably engaged with the wheel front fixing member and the wheel rear support member and amplifies and transmits the swing of the wheel front fixation member to the wheel rear support member, and each member, means A four-bar scalene link is constructed with the engagement means as link nodes, and the forward force of the front wheels urges and swings the wheel front fixing member in the traveling direction, and when the front wheels reach the storage position, the front wheel The two-wheeled vehicle is maintained upright by holding and fixing the front part of the front wheel by the part fixing member, the rear part of the front wheel by the wheel rear support member, and the lower part of the front wheel by the base member. At the storage position, any one of the four sections is automatically fixed using a principle similar to that of locking a vehicle door, thereby fixing the movement of the link and maintaining the two-wheeled vehicle upright.
When the rocking of the rear wheel support member is driven by an actuator, etc., a photoelectric sensor or the like detects when the front wheel reaches the storage position, and transmits a signal to the controller of the drive device. An irreversible reducer drives the swinging of the rear wheel support member, and an increase in drive torque occurs at the position where the rear wheel support member presses the rear of the front wheel. Therefore, a means to detect the increase in torque is used to stop the drive of the actuator. When a command is issued to stop the wheel rear support member, the wheel rear support member is automatically fixed at that position, and the front wheel is maintained fixed.

In the case of an invention that uses scalene four-bar links, a trigger for releasing the lock is provided on the fixed member, and the trigger is operated by power or manually to release the fixation of the link joints, thereby locking the front wheels during the unloading process. When the vehicle moves backward, the rear of the front wheel pushes the rear wheel support member backward, or when the vehicle moves backward and the front of the front wheel stops pressing the front wheel fixing member, the front wheel fixing member, the connecting member, and the rear wheel support member are removed. Due to the backward rotational moment caused by gravity, the wheel rear support member falls backward, allowing the wheel to be taken out of the garage.
In the case of the invention in which the rear wheel support member is driven by an actuator, the actuator is driven by operating the exit switch, and the vehicle can be taken out of the garage by tilting the rear wheel support member backward. When the wheel rear support member is tilted back and comes into contact with a predetermined stopper or the like, the movement of the drive means is stopped by the action of the controller due to an increase in drive torque or the like.

A string or the like with a cap-like member inserted into the tip of a lever, etc. of a handlebar of a two-wheeled vehicle is tied to the trigger for releasing the locking of the link joints of the invention using scalene four-bar links, and the cap is attached to the handlebar of a two-wheeled vehicle. By inserting the trigger into the tip of the lever, the trigger can be operated in the release direction to unlock the lock member by squeezing the handle lever. In the case of an invention in which an actuator is used to drive the wheel rear support member, the exit switch may be supported on the two-wheeled vehicle handle. In this way, it becomes possible to leave the garage by maintaining support for the two-wheeled vehicle handle with both hands and operating the switch with the fingertips.

The bicycle parking device of the present invention does not require any skill to use, and is convenient because it is possible to enter and exit the bicycle without taking your hands off the handlebars or making any operations with your feet. Excellent and safe. This effect is particularly noticeable for heavy vehicles. Furthermore, it is easy to move a two-wheeled vehicle forward due to its mechanical configuration, and it is very rational to use its forward force as driving energy for each front wheel fixing member.

FIG. 2 is a detailed view of the attachment portion of the wheel front fixing member 4500 to the base member 100.

As shown in FIG. 1, this embodiment is a member that forms a wheel entry path and fixes the lower part of the wheel, and is provided with a lock pin 120 at the upper front end, and a bottom surface 101 that is in contact with the floor of a building, the outdoor ground, etc. has a plurality of holes 164 for attachment to a floor surface etc. with fastening members 162, has wall surfaces 105 on both sides of the bottom surface 101, and has a wheel front fixing member attachment hole 102 and a wheel rear support member on both side wall surfaces 105. A base member 100 that has a long hole 104 for attaching a support plate 710 and a fixing member 166 for fixing a rope or the like for auxiliary fixing of a vehicle, and is fixed to the floor surface with a fastening member 162 or the like, and both walls 105 of the member 100. A bracket 501 is attached to the upper end of the mounting hole 102, a locking member 520 is attached to the bracket 501, and as shown in FIG. A wheel front fixing member 4500 having a shape such as the above is rotatably supported by screwing a fastening member 504 passing through the attachment hole 102 into the screw hole 502 thereof.

3 is a side view of the wheel rear support member attachment plate 710, FIG. 4 is a front view thereof, and FIG. 6 shows its front sectional view.

Elongated holes 104 are provided in both walls 105 of the foundation member 100 at a predetermined distance behind the hole 102, and the wheel rear support member mounting plate 710 is connected to the elongated holes 104 in the elongated holes 104 of both walls 105. It is attached with a bolt 704 passing through a mounting hole 711 and a nut 754, and when the bolt is loosened, the plate 710 can change its position in the vehicle direction relative to the base member, and when the bolt 704 is tightened, the position is fixed. Supported. In FIGS. 3 and 5, there are two mounting holes 711 and two mounting bolts for one plate 710, but it may be one.
A fastening member 714 rotatably passes through a hole 712 provided in the plate 710, and a wheel rear support member 700 having a trapezoidal cross section and a convex portion 718 and a convex portion 706 are provided on the trapezoidal slope 701. A fastening member 714 passing through the hole 712 is screwed into a screw hole 713 of the convex portion 718 and is swingably attached.

When the wheel rear support member 700 is in the position shown in FIG. 1 and FIG. The distance from the center of the screw hole 713 of the convex mounting member 700 to the lower side of the bottom 701 is made equal to the distance from the top surface of the bottom 101 of the base member 100 to the hole 712 of the mounting plate 710. . Therefore, when the bottom 701 of the wheel rear support member 700 contacts the base member bottom 101, they contact each other in parallel, and the entire surface of the bottom 701 of the wheel rear support member 700 contacts the top surface of the bottom 101 of the base member 100. . Therefore, the difference in level between the top surface of the bottom 101 of the foundation member 100 and the wheel rear support member 700 is only the thickness of the bottom 701 of the wheel rear support member 700, and the wheel 1300 can slide over the bottom 701 of the wheel rear support member 700 without resistance. Can pass. At this time, the wheel front fixing member 4500 is in a position inclined slightly to the right, and the lock member 520 and the lock pin 120 are set to maintain a predetermined distance. Note that a hole may be provided in the base member bottom 101 into which the bottom 701 of the wheel rear support member fits without interference, thereby eliminating the level difference between the wheel rear support member bottom 701 and the base member bottom 101. Further, the rear end of the bottom 101 of the base member 100 may be made forward of the front end of the bottom 701 of the wheel rear support member 700, so that there is no difference in level between the bottom 701 of the wheel rear support member and the base member 101.

FIG. 7 is a detailed view of a connecting portion between the connecting member 900, the wheel front fixing member 4500, and the wheel rear support member 700. A part of FIG. 8 represents the coupling means and a side view thereof. The connecting means 900 includes a turnbuckle main body 934 having threaded holes in opposite directions at both ends, an output shaft 931 having a screw that fits into the threaded holes and an L-shaped portion 920 at the end, and a turnbuckle main body 934 at the end. The output shaft 939 has a plate 932 having a plurality of mounting holes 930 at the other end.

The L-shaped portion 920 of the connecting member 900 is swingably fitted into a hole 506 provided in the wheel front fixing member 4500 with a retaining ring or the like, and one of the attachment holes 930 is fitted into a hole 506 provided in the wheel front fixing member 4500 . The convex portion 706 is swingably fastened to the screw hole 703 by a fastening member 702 . Although FIG. 7 shows an example in which two connecting members 900 are used on both sides of the vehicle, one connecting member 900 may be used on one side of the vehicle side.

FIG. 8 shows the details when the wheel 1300 is fixed, ▲1▼ a pair of members of the base member 100 and the wheel rear support member attachment plate 710 fixed to the base member, and ▲2▼ the rocking on the base member 100. The wheel front fixing member 4500 is movably coupled; (3) the wheel rear support member 700 is swingably coupled to the wheel rear support member mounting plate 710; (4) the wheel front fixing member 4500 and the wheel rear The scalene 4 of the connecting member 900 that swingably connects the support member 700 is configured such that the four members or means are the four sides of the link, and the connecting means that swingably connects each member is the four link nodes. Indicates a clause link. The two-dot chain line represents the virtual link side. The position of each node and the contact positional relationship with each member constituting the link of the wheel 1300 are also shown. It is also a side view of the attachment of the connecting member 900 as described above.

The joint part 502 between the foundation member 100 and the wheel front fixing member is a link node A, the joint part between the wheel front fixing member 4500 and the connecting member 900 is a link node B, and the joint part between the connecting member 900 and the wheel rear support member 700 is a link node. Node C, the joint between the wheel rear support member 700 and the wheel rear support member attachment plate 710 is the link node D, the distance between the nodes AB is Xf, the distance between the nodes CD is Xr, and the node A and the wheel front fixing member. 4500 and the distance from the contact point 1302 of the wheel 1300 to Wf, and the contact point between the wheel rear support member and the wheel 1300 from the node D to Wr, the relationship between these is that Xf is larger than Xr, and The ratio Xf/Wf of Link so that the distance from the line of action to node C, that is, the moment arm M1, is smaller than the distance M2 from the line of action to node C when the wheel rear support member is raised to the position where it contacts the rear of the front wheel. Set the position of the section CD,
In the condition ▲1▼ above, the intersection angle between the straight line connecting link node AB and the straight line connecting link node AB is close to 90 degrees, and in the condition ▲2▼ above, the axis intersection angle deviates from 90 degrees. Set scalene four-node links so that they are in the related positions.

If the angle change of the wheel front fixing member 4500 relative to the base member 100 due to the position of the set link node is defined as a swing angle α, then the swing angle β, which is the angle change of the wheel rear support member 700, becomes larger than α. Further, the differential value dβ/dα of β with respect to α becomes smaller as the swing angle α of the wheel front fixing member 4500 becomes larger. This characteristic allows a larger swing angle of the wheel rear support member 700 and a larger wheel 1300 rear pressing support force of the wheel rear support member 700 to be compatible.
When the wheel 1300 reaches the storage position and the wheel front fixing member 4500 swings to a predetermined position, the locking member 520 bites the lock pin 120 and the wheel front fixing member 4500 is fixed to the base member 100. Rocking is fixed. Therefore, the swinging of each member constituting the link side is fixed, and the fixation of the wheel 1300 is maintained.

The diameter of the wheels 1300 of a two-wheeled vehicle varies greatly depending on the vehicle type. As a means to deal with this, it is necessary to change the distance between the link nodes AD and BC. In this embodiment, the distance AD can be changed by loosening the bolts 704 that fix the wheel rear support member attachment plate 710 to the base member 100, so that the wheel rear support member attachment plate 710 can be moved relative to the base member 100 in the longitudinal direction of the vehicle. Move to .
The distance BC can be changed by providing multiple holes 930 and a turnbuckle body 934 in the connecting member 900, and large length adjustments can be made by changing the mounting position of the multiple holes 930, and fine adjustments can be made using the turnbuckle body 934. By carrying out the above operations, it becomes possible to accommodate vehicles having wheels 1300 with greatly different diameters.

FIG. 9 shows the trapezoidal bottom portion 701 of the wheel rear support member 700, the unevenness 721 and 113 provided at the wheel contact portion at the bottom of the base member 100, the fastening member 162 for fixing the base member to the floor etc., and the fastening member. A mounting hole 164 is shown therethrough. The unevenness can prevent the wheel 1300 from skidding by increasing the friction with the wheel tire, and can further stabilize the fixation of the wheel. The fastening member 162 is located at a position where it does not interfere with the wheel 1300 so as not to obstruct passage of the wheel.

An embodiment of the locking member 520 is shown in FIGS. 10, 11, and 12. FIG. 10 shows the state of the locking member 520 before locking. FIG. 11 shows the hook 522 biting and locking the lock pin 120. FIG. 12 shows a state in which the hook 522 and the lock pin 120 are released by operating the trigger 524.

FIG. 13 shows a state in which a two-wheeled vehicle is parked. The wheel 1300 is fixed between the front wheel fixing member 4500 and the rear wheel support member 700, and the hook 167 at the end of the auxiliary fixing rope 168 is hooked onto the rope fixing member 166 provided on the base member 100. The hook 165 at the other end of the rope is hooked onto the vehicle body 169 of the two-wheeled vehicle and fixed.
Further, a cap 546 of a rope 544 having a cap 546 and a length adjusting means 554 at the end fastened to the hole of the trigger 522 of the locking member 520 is inserted into the end of the lever of the vehicle handle.

The lock member 520 is rotatably attached to a bracket 501 provided at the V-shaped tip of the wheel front fixing member 4500 by a fastening member 502 passing through a hole 531 of the bracket 501 . A hook 522 having a slope 523 at its tip, a trigger 524, an elastic body attachment hole 526, and an elastic body 529 connecting the hole 526 and the bracket 501 are attached to the hole 503 of the bracket 501, and the hook 522 engages the lock pin 120. Apply rotational moment in the direction of compression. A stopper member 537 is provided on the bracket 501, and the position of the stopper member 537 is such that when the lock member 520 is not biting the lock pin 120 as shown in FIG. When the pin 120 and the hook 522 start contacting each other, the hook slope 523 first contacts the pin 120, and when the hook 522 is biting and locking the lock pin 120 as shown in FIG. The hook 522 and the stopper member 537 are provided at a position where they do not come into contact with each other.

As the wheel front fixing member 4500 is pressed and swung by the wheel 1300, the slope 523 of the hook 522 of the locking member 520 comes into contact with the lock pin 120, and as the rocking progresses further, the hook 522 is moved by the action of the slope 523. When the user rides on the pin 120 and moves further while deforming the elastic body 529, the pin 120 is held by the action of the elastic body 529 as shown in FIG. At this time, as described above, the gap between the hook 522 and the stopper member 537 is maintained, and the hook 522 sufficiently engages the lock pin 120. Therefore, node A, which is one node of the scalene four-bar link, is fixed, and the wheel 1300 is maintained fixed. As shown in FIG. 11, a sensor 119 may be provided on the lock pin 120 so that when the hook 522 reaches a securely locked position, a warning light is activated to determine whether or not the lock is securely locked. can.

If necessary, a hook 167 at the tip of a tie-down belt or the like 168 is hooked onto a rope fixing member 166 provided on the base member 100 and constituted by an eye bolt in this embodiment. You can also secure the vehicle in an appropriate position and tighten the belt to further secure the vehicle.

As shown in FIG. 13, if a rider or the like is using the auxiliary fixing belt 168, remove it, or if the auxiliary fixing belt 168 is not used, directly attach the lever to the vehicle handlebar into which the cap 546 is inserted. By squeezing the trigger, the trigger is pulled to the right in FIG. 12, the hook 522 is lifted off the lock pin 120, the lock pin is released, and the scalene four-bar link is released. Therefore, the wheel front fixing member 4500, which is one side of the link, can swing.

When the two-wheeled vehicle is moved rearward in this state, the wheels 1300 press the wheel rear support member 700 rearward, and the wheel rear support member 700 as well as the wheel front fixing member 4500 have their bottoms pressed against the base member bottom 101. It falls backwards until it makes contact. Therefore, the wheels 1300 can pass over the wheel rear support member 700, as shown in FIG. 1, and the two-wheeled vehicle can be removed from the bicycle parking device. The locking means and its release means may be provided at any of the four nodes ABCD. This is because if one of the four nodes is fixed, the four-section link is fixed. The two sections may be provided with a fixing means and a releasing means, one of which may be automatic, and the other with an unlocking key mechanism to serve as theft prevention means.

In FIG. 14, the wheel rear support member 700 is directly attached to the elongated hole 0104 of the base member 0100 without using the wheel rear support member attachment plate 710, and the position of the rocking center node D can be changed in the front-rear direction. An example of mounting a wheel rear support member 700 that can be changed to change the distance between nodes AD is shown.

A screw hole 715 provided in the convex member 718 of the rear wheel rear support member 700, a bolt 7011 having a hole 7013 inside fitted into the elongated hole 0104, and a nut 7019 that fixes the bolt 7011 to the elongated hole 0104 of the base member 0100. , a bolt 7015 passing through a hole 7013 of a bolt 7011. The threaded portion of the bolt 7015 fits into the threaded hole 715 and has a shaft portion 7017 that is thicker than the threaded portion, and the shaft portion 7017 has a diameter that allows it to fit and slide in the bolt hole 7013. The length of the shaft portion 7017 is made longer than the entire length of the bolt 7011.

Therefore, even if the bolt 7015 is tightly tightened into the screw hole 715 provided in the convex member 718 of the wheel rear support member 700, the slidability between the hole 7013 and the bolt 7015 is maintained, and the base member 0100 of the wheel rear support member 700 The fluctuation is maintained. By loosening the nut 7019, the bolt 7011 can change its longitudinal position with respect to the elongated hole 0140, and by tightening it, the position is fixed. Therefore, without using the wheel rear support member attachment plate 710, it is possible to change the distance between nodes AD or to fix it at a predetermined distance while allowing the wheel rear support member 700 to swing. .

As described above, the wheel front fixing member 4500 has a V-shaped cross section to prevent the wheel 1300 from falling in the lateral direction, and the wheel rear support member 700 has a trapezoidal cross section and the bottom 701 of the wheel rear support member 700 Since the wheel 1300 with the thick tire is flat, when the wheel 1300 with the thick tire falls backward and passes, the tire side surface does not come into contact with the trapezoidal side surface and the wheel 1300 shown in FIG. When placed in this position, it prevents large lateral displacement of the wheels and ensures wheel fixation. The bottom 701 of the wheel rear support member 700 does not need to be flat as long as it has a smaller curvature than the cross-sectional curvature of the thick tire.

In this embodiment, there is no means for adjusting the distance between the nodes BC and the distance between the nodes AD of the scalene four-bar link, that is, the length of the connecting member 900 is fixed, and the position of the knot D is fixed. But that's fine. If the type of vehicle to be parked is fixed due to a contract or other reason, the diameter of the wheels 1300 is constant, so the length of the connecting member 900 and the center of swing of the wheel rear support member 700, that is, the scalene four-bar link This is because there is no need to adjust the position of node D, and the structure becomes simpler.

As described above, in this embodiment, when entering or exiting a garage, it is possible to enter the garage by simply pushing the two-wheeled vehicle forward without taking both hands off the handle, and by grasping the handle lever etc., the vehicle can be moved backwards. You can exit the bicycle parking device by simply moving to the bicycle parking device. Furthermore, two-wheeled vehicles are easy to move forward due to their structural form. For this reason, it is extremely rational to use the forward energy of the front wheels as the drive source for each front wheel fixing member.Furthermore, it is a simple mechanism that applies the movement of scalene four-bar links, is highly reliable, small, lightweight, and inexpensive. .
Furthermore, in order to securely fix the vehicle, when fixing or releasing the vehicle using a tie-down belt 168 or the like as necessary, the vehicle is secured with the wheels 1300 sandwiched between the front wheel fixing member 4500 and the rear wheel support member 700. Since it is independent, its operation is easy. The connecting means 900 of this embodiment is composed of a link side, but also uses a non-circular gear train, an eccentric sprocket and a chain, two hydraulic cylinders, etc. to connect the wheel front fixing member and the wheel rear supporting member. Good too.

An example of Example 2 is shown in FIGS. 15 and 16. FIG. 15 is a diagram in which the one-way clutch mechanism 580 is arranged at node A of the scalene four-bar link, that is, the center of swing of the wheel front fixing member 4500, and FIG. 16 is a diagram showing the latch 588 and trigger 582 of the one-way clutch mechanism 520. A detailed diagram is shown.

Embodiment 2 replaces the locking member 520 of Embodiment 1 with a latch 188 of a one-way clutch mechanism 580 having a circular or fan-shaped outer periphery and 132 holes through which a fastening member for attaching the wheel front fixing member 4500 is passed through the center thereof. is a bracket for fixing the center hole of the member at the position of the link node A of the outer wall 105 of the base member 100 by a fastening member or welding, etc., and for attaching the trigger mechanism 582 to a predetermined position on the same plane as the latch 188. 592 is attached and fixed to the wheel front fixing member 4500, and the trigger 582 is rotatably attached to the bracket 592 by a shaft such as a bolt 591. Further, an elastic body 586 connects the trigger and the bracket 592. This structure includes a one-way clutch mechanism 580 that allows the wheel front fixing member 4500 to swing the node A only in the left direction in FIG. A mechanism that enables movement can be realized.

The outer circumferential portion 588 of the latch 188 is provided with teeth 593, and the tooth shape has a gentle slope on the surface that contacts the trigger 582 when it swings to the left together with the wheel front fixing member 4500, and when it engages with the trigger tooth tip 581. The common normal line passes above the center of the mounting bolt 591, which is the center of rotation of the trigger in FIG. 16. The tooth surface on the opposite side of the latch tooth type 593 has a steep slope on the surface that contacts the trigger tooth tip 581, and the common normal line of engagement with the trigger tooth tip 581 passes above the center of the mounting bolt 591, which is the rotation center of the trigger. It is shaped like this.
The trigger has a tooth tip 581 that meshes with the latch tooth 593, an elastic body attachment arm 583, a trigger arm 582, a rotation center hole 581, and an elastic body attachment arm 583, and an elastic body 586 is connected between the arm 583 and the hole 597 of the bracket 592. It is connected with.

The shape of the tip 581 of the trigger tooth that engages with the latch tooth 593 is made equal to the valley shape of the latch tooth 593, and has a shape that engages with the latch tooth. Therefore, when the wheel front fixing member 4500 swings together with the trigger 582 to the left in FIG. While receiving the moment and deforming the elastic body 586, the tooth tip 581 is lifted from the latch teeth 593, and the connection between the two is released. Therefore, leftward rocking of the wheel front fixing member 4500 is not inhibited. Since the elastic body 586 always applies a counterclockwise rotational moment to the trigger, as soon as the tooth tip 581 passes over the peak of the latch teeth 593, it immediately returns to the engaged state.

If you try to swing the wheel front fixing member 4500 to the right while the latch teeth 593 and the latch teeth 581 are engaged, the trigger will not engage with the tooth tips 581 and the latch teeth 593 in the common normal direction. The force acts, creating a moment of counterclockwise rotation in the direction of the teeth becoming more and more engaged, but never coming out of engagement.

When the wheel 1300 presses the wheel front fixing member 4500 forward, the wheel front fixing member 4500 does not return from that position in the opposite direction relative to the base member 100 due to the action of the one-way clutch mechanism 580, as described above. Therefore, when the wheel front fixing member 4500 is pressed to a predetermined position by the wheel 1300, the wheel rear support member 700 presses the rear of the wheel 1300 by the action of the connecting member 900, and the wheel 1300 is connected to the wheel front fixing member 4500. The two-wheeled vehicle is held between the wheel rear support members 700 and fixed independently, and even if the forward pressing of the wheels 1300 is stopped, this state is maintained by the function of the one-way clutch 580. The force that pinches the wheel 1300 has a value that uniquely corresponds to the force with which the rider presses the wheel front fixing member 4500 with the wheel 1300.

When the one-way clutch mechanism 580 is in the locked state, if the trigger arm 582 is moved to the right in FIG. 17, the trigger rotates clockwise about the mounting hole 506. As a result, the trigger tooth tip 581 lifts up from the latch teeth 593, the one-way clutch 580 is unlocked, node A of the scalene four-bar link is free to swing, and the scalene four-bar link swings in the right direction. becomes possible.

When the wheel 1300 is moved rearward in this state, the wheel rear support member 700 falls backward, and the two-wheeled vehicle can be removed from the bicycle parking machine.

The one-way clutch and trigger shown in FIGS. 15 and 16 are an embodiment of the present invention, and since the main invention of the present invention is an application of a scalene four-bar link, the link mechanism swings in the counterclockwise direction. Any device may be used as long as it has a means for allowing only the movement of the object and a means for stopping that function and allowing movement in the right direction or in both left and right directions. Further, the means may be provided at any of the four nodes ABCD of the scalene four-node link. The means for stopping the function of the one-way clutch and freeing the swinging of the linkage may be driven not only manually, but also by using actuators such as a solenoid, motor, pneumatic, hydraulic, etc.
In this case, the actuator switch may be linked with a fare box or card reader so that the link works in the locking or releasing direction only when a predetermined fee is paid.

As described above, by using the one-way clutch mechanism, it is possible to fix the wheel front fixing member 4500 in any freely swinging position, and even if there is a difference in the diameter of the wheel 1300, it is automatically corrected and a reliable The wheels can be fixed. When the diameter of the wheel 1300 is small, if the wheel front fixing member 4500 is moved and pressed further forward by the wheel 1300, the wheel rear support member 700 swings more due to the action of the connecting member 900, and the wheel 1300 is moved backward. This is because the pressure is applied from

This example is an example in which the rigidity of the connecting member 900 in Example 1 is lowered. FIG. 17 shows the shape of a connecting member 901 that connects the wheel front fixing member 4500 and the wheel rear support member 700. The output shaft 1930 on one side of the turnbuckle body 934 is bent into one or more waves to reduce the rigidity in the tensile direction. Although FIG. 17 shows an example in which only one side 1930 of the output shaft of the turnbuckle body 934 is corrugated, both shafts may be corrugated.
If the vehicle to be used is limited, the diameter of the wheel 1300 is constant, so a structure in which the turnbuckle body 934 is not used and the multi-hole plate 922 is coupled to the output shaft 1930 may be used. Moreover, the number of multiple holes 930 may be one.

In FIG. 18, the output shaft 1931 of the turnbuckle body 934 of the connecting member 902 is processed into a coil shape to reduce the rigidity in the pulling direction. In FIG. 11, only one side of the output shaft is coiled, but both sides may be used. If the vehicle to be used is limited, the turnbuckle main body 934 may not be used, and the output shaft 1932 and the multi-hole plate 922 may be directly coupled. Further, the number of holes 930 may be one.

In FIG. 19, a connecting member 903 is constructed by joining a tension coil spring 1932 to a multi-hole plate 1922, and a stopper 150 for restricting rightward rocking of the wheel front fixing member 4500 is attached to the base member. be. Although this embodiment is different from the present embodiment and belongs to the first embodiment, when the stopper 150 is provided, the connecting means may be a chain or the like. Furthermore, the length of the connecting means can be adjusted by changing the fixing position of the chain between the wheel front fixing member 4500 and the wheel rear support member 700.

The positions of the node fixing means and release means in this embodiment are set at the node A between the base member 100 and the wheel front fixing member 4500 or the node D between the base member 100 and the wheel rear support member 700.

The reason for installing the stopper 150 is that in the case of a tension spring, the supporting force in the compression direction is insufficient and it is difficult to hold the wheel front fixing member 4500 in a predetermined position. Instead of a tension coil spring, a rubber string or the like may be used. The connecting member 903 does not use the turnbuckle body 934. This is because it can be handled simply by changing the mounting position of the multi-hole plate. Furthermore, if the types of bicycle-parked vehicles are limited, the multi-hole plate 922 may have only one hole 930.

Even if the model is the same, the diameter of the wheel 1300 changes due to tire wear and changes in air pressure. At this time, as shown in Embodiment 3, by lowering the rigidity of the connecting means 901, 902, and 903 in the pulling direction, even if the diameter of the wheel 1300 changes somewhat, the length of the connecting member 900 can be adjusted and the rear part of the wheel can be adjusted. Without adjusting the position of the support member 700, it is possible to minimize the change in the force of the wheel front fixing member 4500 and the wheel rear support member 700 pressing against the wheel 1300, and it is possible to securely hold the wheel 1300. Become.

FIG. 20 shows a side view of this embodiment. The front contact portion of the wheel 1300 on the base member 100 has a V-shaped cross section as in the other embodiments.The contact portion with both walls of the base member 100 has a U-shaped cross section, and the bottom of the U-shape faces forward. The fastening member has an elongated hole 584 extending in the front-rear direction through which the fastening member passes through, and has a long hole 584 extending in the front-rear direction so that the fastening position can be changed back and forth with respect to the base member. A wheel front fixing member 4500 fixed to the base member 100 at 586, a wheel rear support member 700 supported so as to be swingable about a horizontal axis that is perpendicular to the base member 100 behind it, and the swing center axis. The electric motor 781 and the irreversible deceleration mechanism 788 such as a worm are loosely inserted into the hole provided in the swinging center of the wheel rear support member 700 on the wall of the foundation member 100, and the swinging speed provided in the wheel rear support member 700 is A drive unit 780 consisting of a drive shaft that fits into a hole in the shaft and is fastened with a key or the like, a floodlight 582 attached to a bracket 581 of a wheel front fixing member 4500, and a wheel front that receives the light and converts it into a signal. A light receiver 583, a current detector 783, a controller 784, and an exit switch 786 are shown attached to the lower part of the fixing member. In the case of this embodiment, the drive unit 780 is fixed to the wall surface of the base member 100 with a fastening member 788 so that the drive shaft is at the center of swing of the wheel rear drive member, and the output shaft of the drive body is attached to the wheel rear support member 700. It has the functions of driving the swing and holding the swing center position. The drive shaft and the driven shaft of the wheel rear support member may be driven via a coupling, gear, chain, or the like.

Optical sensors 582 and 583 that detect when the wheels 1300 have reached the storage position detect the arrival of the front wheels and send a signal to the controller 784, and the controller 784 drives the drive unit to move the wheel rear support member 700 to the backward position. From there, swing the front wheel to a position where it presses the rear part of the front wheel. When the rear wheel support member reaches a position where it presses the rear of the front wheel, the load on the motor increases and the current flowing through the ammeter 783 increases. The controller 784 detects the current value or current change (differential value of current with respect to time) and stops driving the motor. As described above, since the speed reducer is an irreversible speed reduction mechanism, the wheel rear support unit remains in the position where the front wheel rear is fixed and the storage is maintained.
If the diameter of the wheel 1300 differs depending on the vehicle type, the fastening member is loosened, the wheel front fixing member 4500 is adjusted in the front-back direction with respect to the base member, and then the fastening member is tightened to fix the position.

When leaving the garage, by operating the exit switch 786, the controller drives the motor, the wheel rear support member falls backward to a position where the front wheels can pass over it, and is prevented from swinging by the stopper 789, and due to changes in the motor current. The controller stops the motor. The stopper is preferably made of elastic material such as rubber.

The means for stopping the drive of the wheel rear support member at a predetermined position includes supporting the drive unit with an elastic body so as to be able to swing around the drive axis, and using a position sensor to measure the angle at which the unit swings due to changes in the drive reaction force. A method of detecting this and stopping the motor may also be used.
