[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the bicycle parking device of the present invention will be described.
[0012]
FIG. 1 is an overall side view showing an embodiment of a bicycle parking device according to the present invention, and FIG. 2 is a front view of the device of FIG.
[0013]
As shown in the figure, the bicycle parking device includes a base 11 fixed to a floor and a support 12 fixed vertically to the base 11, and a lock mechanism for locking a front wheel of the bicycle to the base 11. 20 is fixed, and an operation box 30 for the operator to insert coins into the column 12 and perform an unlocking operation is fixed.
[0014]
The operation box 30 serves as a mechanism for unlocking a front wheel by a lock mechanism 20 described later. The coin insertion slot 32, an operation lever 31 that can be operated by inserting a coin, and a rotation of the operation lever 31 2, a lock plate 33 that moves in the left-right direction in FIG. 2, a lever 34 that rotates integrally with the operation lever, and a coin box (not shown) that stores inserted coins. Although not shown in FIGS. 1 and 2, a mechanism is provided in the coin insertion passage for restricting the movement of the operation lever 31 and the like. These mechanisms will be described later.
[0015]
The lock mechanism 20 includes a V-shaped rail member 22 supported by a shaft 21 fixed to the base 11, a spring (not shown) for urging the rail member 22 clockwise in FIG. The wire 23 is fixed to the rail member 22 and the other end is fixed to (a wire fixing portion of) the lever 34 in the operation box 30. A wire guide 24 for guiding a wire 23 is fixed to the column 12.
[0016]
The rail member 22 has a U-shaped cross section perpendicular to the longitudinal direction, and the front tire can be placed in the U-shaped groove. Further, the rail member 22 is positioned between the position where the right side of the shaft 21 is parallel to the base 11 and the position where the left side of the shaft 21 is parallel to the base 11 as shown in FIG. It is possible to rotate. Further, the rail member 22 is connected to a link rod 25, and the link rod 25 is guided by a rod guide 26 fixed to the column 12, and is supported so as to be vertically movable in parallel with the column 12. The link rod 25 moves up and down with the rotation of the rail member 22 about the shaft 21.
[0017]
The above-mentioned lock plate 33 of the operation box 30 can move between a position where the movement path of the link rod 25 is closed and a position where the movement path of the link rod 25 is not closed, and the rotation of the lever 34 to which the wire 23 is fixed causes the link rod 33 to rotate. Move to a position that blocks the 25 motion paths. This constitutes a locking means for locking the vertical movement of the link rod 25, that is, the rotation of the rail member 21. The lock plate 33 is retracted from the movement path of the link rod 25 by operating the operation lever 31.
[0018]
Further, in the bicycle parking device of the present embodiment, as shown in FIG. 2, a slit 13 through which a front tire can penetrate is provided in a part of the support 12. The width of the slit 13 is designed to be slightly larger than the front wheel tire, and the length is designed to be smaller than the diameter of the front wheel. Preferably, an upper end plate whose position is variable is attached to the upper end of the slit so that the length of the slit 13 can be changed according to the diameter of the bicycle tire.
[0019]
In such a configuration, first, a case where the bicycle is locked to the bicycle parking device will be described.
[0020]
In a state where the bicycle is not provided in the bicycle parking device, as shown in FIG. 1, the V-shaped rail member 22 has a position where the right side of the shaft 21 is parallel to the base 11, so that the front tire of the bicycle can be easily mounted. ing. In this state, when the front wheel tire is placed on the rail member 22 and moved forward, the pressing force causes the rail member 22 to rotate counterclockwise against the spring, and assumes a position as shown in FIG. It passes through 12 slits 13 and stops at the upper end thereof. By the rotation of the rail member 22, the link rod 25 is pulled downward from the lock plate 33 of the operation box 30. At the same time, the wire 23 fixed to the rail member 22 is pulled downward, and the lever (wire fixing portion) 34 of the operation box 30 is rotated. Due to the rotation of the lever 34, the lock plate 33 moves right above the link rod 25, and locks the return of the link rod 25, that is, the return of the rail member 22.
[0021]
In this state, unless a coin is inserted into the operation box 30, the operation lever 31 for operating the lock plate 33 cannot be rotated reversely, and the locked state is maintained.
[0022]
At this time, the movement of the front portion of the front wheel tire in the direction perpendicular to the slit is restricted at the upper end A and the lower end A ′ of the slit 13 provided in the column 11, as shown in FIG. Further, the rear portion C of the rail member 22 restricts the front wheel from retreating and coming out of the slit 13. Further, the distance between the rear portion C of the rail member 22 and the upper end A of the slit 13 is smaller than the diameter AD of the front wheel tire, so that the front wheel cannot be pulled out of the slit 13 even if the front wheel is lifted. In this way, the movement of the bicycle in the front, rear, left, right, and up and down directions is restricted, and a stable posture can be maintained without falling down, and theft can be prevented.
[0023]
Next, a case of releasing from such a locked state will be described.
[0024]
FIG. 3 shows a detailed configuration for unlocking the operation box 30.
[0025]
As shown in FIGS. 4A and 4B, the operation box 30 has a coin insertion slot 32 and an operation lever 31 on the entire surface, and when a coin is inserted through the coin insertion slot 32, the operation lever 31 is vertically moved. (A), the operation lever 31 rotates the coin to the coin storage box 35, rotates the wire connecting portion 34, and causes the wire 23 to rotate. It is configured to interlock with pulling in the direction.
[0026]
FIGS. 4C and 4D show details of the lock release mechanism. FIG. 4C shows the mechanism viewed from the front, and FIG. 4D shows the mechanism viewed from the side.
[0027]
In the illustrated configuration, the lock plate 33 moves left and right with the rotation of the operation lever 31, but the lock plate 33 is in the leftward position (lock position) in FIG. 4D and no coin is inserted. In this case, the door plate 312 rotatably mounted is in a position to close the opening 311 by its own weight, and the rightward movement of the lock plate 33 in FIG.
[0028]
On the other hand, when a coin is inserted from the coin insertion slot 32, the coin lifts the anti-reverse link 313, 314, enters a predetermined coin passage, falls, and comes into contact with a protrusion 315 provided on the door plate 312. The door plate 312 is rotated to a position where the opening 311 is not closed, and the door plate 312 is stopped in a state 320 in which the drop is prohibited by the protrusion 317 of the coin pressing plate 316. In this state, when the operation lever 31 is rotated clockwise in FIG. 4C, the lock plate 33 moves rightward through the opening 311 and the coin pressing plate 316 moves rightward in FIG. Release the pressing. The coin pressing plate 316 from which the pressing has been released rises to the left in FIG. 4C, and the coins that have been prohibited from falling by the projections 317 of the coin pressing plate 316 are released, and fall into the coin storage box 35 located below. .
[0029]
When the bicycle is pulled backward with the lock plate 33 moved rightward, the rail member 22 returns to the position shown in FIG. 1 by the urging force of the spring, and at the same time, the link rod 25 protrudes above the lock plate 33. Return to the position Thus, unlocking and coin collection are performed.
[0030]
