On the contrary, when the rod 42a moves away from the front wheel FW of the motorcycle, the tip of the rod 42a is in a non-contact state with the adjusting screw 32, and the adjusting screw 32 does not receive the pressing force from the rod 42a.

At the center of the lower surface of the second moving table 31, an adjusting tool mounting board 31a constituting a pressing adjusting tool is fixedly installed together with the adjusting screw 32. A spiral hole is formed in the adjuster mounting board 31a in the moving direction of the second moving table 31. The adjusting screw 32 pressed from the tip of the rod 42a is screwed into the spiral hole, and can be moved back and forth by a screw motion in the moving direction of the second moving table 31. By finely adjusting the adjusting screw 32 back and forth by screw movement and moving it, the distance between the tip of the rod 42a and the adjusting screw 32 can be finely adjusted.

In the second moving table 31, the tip of the rod 42a of the lock and unlocker 42 presses the adjusting screw 32 toward the rear side of the upper frame 1, that is, toward the front wheel FW of the motorcycle, so that the adjusting screw 32 is screwed. The front wheel FW of the motorcycle is locked by moving the lock stroke S2 to the rear side via the matching adjuster mounting plate 31a.

The lock and unlocker 42 moves the second moving base 31 by the lock stroke S2 through the rod 42a, the adjusting screw 32 as the pressing adjuster, and the adjusting tool mounting board 31a to enable locking and unlocking.

The rod 42a moves back and forth through the insertion hole inside the tubular fixture by pinching the tip side of the front wheel FW of the motorcycle from both sides with the pinching plate 11 and temporarily tightening it so that it does not fall, and finally the pinching plate. The case where the front wheel FW is further firmly pressed from both sides by 11 so that the front wheel FW is not completely disengaged from between the sandwiching plates 11 and the case where the lock is released. The front wheel FW can be locked at any position within the range of the forward amount a to the maximum forward amount ST.

When locking, the rod 42a moves the insertion hole of the tubular fixture attached to the front side surface of the upper frame 1 toward the front wheel FW of the motorcycle by the lock stroke S2. When the lock is released, the opposite is true, and the lock stroke S2 returns in the opposite direction.

The handle lever 42b that operates the lock and unlocker 42 bends in an L shape from the middle toward the base end side and branches to both sides. The base ends of the handle levers 42b branched to both sides are pivotally connected to both side surfaces on the rear end side of the rod 42a, which is inserted through the inside of the tubular fixture, so as to be rotatable forward and reverse. By operating the handle lever 42b, the rod 42a will move back and forth.

One end of the articulated link 42c is pivotally connected to a bent portion of the handle lever 42b that operates the lock and unlocker 42 on the side near the base end so as to be rotatable forward and reverse. The other end of the articulated link 42c is pivotally connected to the outer peripheral side surface of the tubular fixture so as to be rotatable forward and reverse. The articulated link 42c is attached to both sides of the rod 42a with the rod 42a in between.

Next, the operation based on the configuration of the embodiment for carrying out the above invention will be described below.
Before the motorcycle is stored, the moving table 13 provided inside the upper frame 1 of the motorcycle parking device 100 so as to be slidable forward and backward in the forward direction of the front wheel FW of the motorcycle is a setback limit stopper piece protruding from the bottom plate 1b. It is in contact with 21 and stopped. That is, the moving table 13 is provided by the tension spring 26 attached between the spring retaining shaft 24 attached downward to the lower surface side of the moving table 13 and the spring retaining shaft 25 attached upward to the bottom plate 1b of the upper frame 1. It is urged toward the rear, and the stopper receiver formed on the lower part of the rear surface of the center guide support plate 13a of the moving table 13 comes into contact with the retractable limit stopper piece 21 protruding from the bottom plate 1b and stops.

In order to store the motorcycle, the front wheel FW of the motorcycle is moved forward toward the motorcycle parking device 100. A guide plate 52 on which the front wheel FW is placed and guided toward the upper frame 1 is arranged on the front side of the lower frame 2 on the lower side of the motorcycle bicycle parking device 100, so that the front wheel FW is behind the guide plate 52. Enter this from the end side. Since the guide plate 52 is initially tilted downward by the pin 52a whose rear end side is attached in the left-right width direction, the front wheel FW can be smoothly put inside the guide plate 52 and mounted.

When the front wheel FW of the motorcycle is placed in the guide plate 52 and further advanced, the guide plate 52 that tilts back and forth like a seesaw with the pin 52a in the left-right width direction as a fulcrum collapses so that the tip side tilts slightly toward the front side. The rear end side is lifted diagonally upward, and the front end side and the rear end side of the front wheel FW are supported by the V-shaped guide plate 52 to make it difficult to remove the wheel and move forward. A pair of sandwiching plates 11 are opened to the left and right toward the front side of the upper frame 1 in front of the front wheel FW that moves forward.

The front wheel FW is pushed inward toward the inside between the sandwich plates 11 that are open to the left and right. Below the pair of open sandwich plates 11, a center guide 12 that opens in a Y shape toward the front side is provided. When the front wheel FW of the motorcycle is further advanced, it enters the inside of the center guide 12 which is open in the Y shape, and the tip side of the front wheel FW comes into contact with the inside of the Y shape of the center guide 12.

When the front wheel FW of the abutted motorcycle is further advanced, the advancing front wheel FW pushes and moves the center guide 12 forward. Since the center guide 12 that is pressed and moves forward is connected to the center guide support plate 13a whose tip end side is attached downward to the lower surface of the moving table 13, the center guide 12 is connected to the center guide support plate 13a via the center guide support plate 13a. The moving table 13 is moved forward.

At this time, the moving table 13 is moved to the front wheel FW side of the rear motorcycle by the tension spring 26 attached between the spring stopping shaft 24 on the lower surface side of the moving table 13 and the spring stopping shaft 25 of the bottom plate 1b of the upper frame 1. It is always urged toward. However, since the force that presses the center guide 12 of the front wheel FW of the motorcycle forward is greater than the urging force of the tension spring 26, the moving table 13 can be advanced.

Slide guide grooves 23 are attached to both sides of the moving table 13 with the center sandwiched on the lower surface side thereof, and a slide guide support plate 23a that engages with the slide guide groove 23 is attached to the bottom plate 1b of the upper frame 1. Therefore, the moving table 13 moves forward while sliding forward by the slide guide groove 23 and the slide guide support plate 23a.

Shafts 16 are vertically attached to both sides of the moving table 13 that moves forward, and pinions 15a and 15b are attached to the middle of the left and right shafts 16 that are vertically oriented. The rack 17 that meshes with the pinions 15a and 15b is attached to the lower surfaces of the second moving table 31 arranged above the moving table 13 on both the left and right ends, and the front end surface of the rack 17 is the left and right inner surfaces of the upper frame 1. It is in contact with the support plate 18 which is fixed to and functions as a stopper. Therefore, both racks 17 do not advance with respect to the advance of the moving table 13, and the pinions 15a and 15b rotate in conjunction with the advance of the moving table 13. In the drawing, the left pinion 15a rotates counterclockwise and the right pinion 15b rotates clockwise.

The shaft 16 on the rotation center side also rotates in the same direction in conjunction with the rotation of the pinions 15a and 15b. The base end sides of the upper arm 11a and the lower arm 11b are integrally fixed to both upper and lower ends of the vertically facing shaft 16. Therefore, the upper arm 11a and the lower arm 11b rotate horizontally around the connecting portion of the shaft 16 on the proximal end side. When the moving table 13 moves in the forward direction, the left and right upper arms 11a and lower arms 11b rotate inward with their tip sides facing each other.

Left and right sandwich plates 11 are attached to the tip sides of the left and right upper arms 11a and lower arms 11b, respectively. The left and right sandwich plates 11 are formed by rotating the left and right upper arms 11a and lower arms 11b toward the inside facing each other with the base end side as the center, whereby the tip of the front wheel FW of the motorcycle advanced between the left and right sandwich plates 11. Hold the side from both sides and press.

At the maximum forward position of the center guide 12 by pressing the front wheel FW of the motorcycle, the front wheel FW of the motorcycle is temporarily tightened by the left and right sandwich plates 11, and the motorcycle can be stably independent. At the maximum forward position of the center guide 12, the moving table 13 has advanced from the stop position before the movement by the maximum forward amount ST.

After that, the person who parks the motorcycle in the motorcycle bicycle parking device 100 leaves the motorcycle and is attached to the outside of the front side surface of the upper frame 1 of the motorcycle bicycle parking device 100 in front of the motorcycle toward the side. The handle lever 42b of the lock and unlocker 42 is operated in the lock direction.

By the action of the link mechanism of the lock and unlocker 42, the rod 42a whose rear end is pivotally connected to the base end of the handle lever 42b is moved to the tip side by the lock stroke S2 and locked. When the rod 42a moves toward the tip side by the lock stroke S2, that is, moves toward the rear side of the upper frame 1 (advances in the direction of the arrow in FIG. 6), the tip of the rod 42a uses the adjusting screw 32 as a pressing adjuster on the upper frame 1. Press and move toward the rear side of.

The adjusting screw 32, which is pressed by the rod 42a and moves, is screwed into the adjusting tool mounting plate 31a, and the second moving base 31 to which this is attached via the adjusting tool mounting plate 31a is attached to the rear of the upper frame 1. Move only the lock stroke S2 toward the side. The moving distance of the lock stroke S2 in this embodiment is a few millimeters, for example, about 3 mm. However, by slightly moving the adjusting screw 32 as a pressing adjuster back and forth, the lock stroke S2 can be moved according to the usage situation. Of course, you can change the moving distance of.

When the second moving table 31 moves toward the rear side of the upper frame 1 by the lock stroke S2, the racks 17 attached to the lower surfaces on both ends of the second moving table 31 also move in the same direction by the lock stroke S2 and mesh with the rack 17. The pinions 15a and 15b on both sides rotate the upper arm 11a and the lower arm 11b toward the central front wheel FW. In the drawing, the left pinion 15a rotates counterclockwise and the right pinion 15b rotates clockwise.

As a result, the left and right sandwich plates 11 provided on the tip sides of the arms 11a and 11b further pinch the tip side of the front wheel FW from both the left and right sides to hold the bike more firmly, and the bike can be safely and tipped over. The bicycle can be reliably parked in the motorcycle bicycle parking device 100 without any problem.

Next, when the motorcycle is discharged from the motorcycle parking device 100, the handle lever 42b of the locked and unlocked device 42 in the locked state is operated in the anti-locking direction. Then, the rod 42a moves in the backward direction by the lock stroke S2, is pressed by the tip of the rod 42a, and moves by the lock stroke S2 to the rear side of the upper frame 1 via the adjusting screw 32 and the adjusting tool mounting plate 31a. 2 The moving table 31 is pulled back to the original stop position by the urging force of the tension spring 35 when the pressing force from the rod 42a disappears.

At this time, the front end surfaces of the rack 17 on the lower surfaces on both ends of the second moving table 31 pulled back by the tension spring 35 come into contact with the support plates 18 attached to the left and right side surfaces of the upper frame 1 to perform the second movement. The pedestal 31 is pulled back further forward but is prevented. The support plate 18 functions as a stopper.

As a result, the locked state on the tip side of the front wheel FW by the left and right sandwich plates 11 that have been firmly held is released and the bike is returned to the temporarily tightened state, so that the motorcycle can be manually moved backward and the front wheel FW can be moved backward. The bike can be pulled out from between the left and right sandwich plates 11 and the bike in the parked state can be shipped from the bike parking device 100.

As described above, the operation of entering the motorcycle into the bicycle parking device 100 and the operation of leaving the motorcycle can be performed only by one-touch operation of the handle lever 42b of the lock / unlock device 42.

It should be noted that the present invention is not limited to the mode for carrying out the above invention, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
