Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle parking lock device used in a bicycle parking facility. [0002] In order to solve the obstacles caused by abandoned bicycles, bicycle parking facilities are set up by private companies or the government in places where many bicycles are scattered, such as around railway stations and at the entrance to shopping malls. Conventional bicycle parking lock devices are equipped with a bicycle parking lock device in which when a bicycle wheel is mounted, the lever arm closes and rotates to restrain the wheel. In order to close and rotate, it is necessary to move the wheel to a normal position where the wheel hits the lever arm, stop the wheel, and press the input arm of the lever arm. [0003] Therefore, when the bicycle does not stop at the normal position where the wheel is pressed against the lever arm, or once stops at the normal position, the wheel is moved from the normal position before the lock mechanism of the lever arm operates. When the lever arm is moved to the shifted position, the restraining arm portion of the lever arm does not close and rotate to the restraining position, or opens and rotates again to the standby position even after closing and rotating. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to ensure that the lever arm closes and rotates to accurately restrain the wheel even if the wheel of the bicycle deviates from the proper position and stops. It is an object of the present invention to provide a locking device for parking bicycles. [0005] The lock device for parking a bicycle according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. When the lever arm 1 is pressed, the lever arm 1 is closed and rotated from the standby position to the restricted position,
A locking mechanism for locking the lever arm 1 to the locking position, the wheel holding mechanism 6 holding the wheel 4 in a wheel-holding position. 8, the longitudinal direction of the wheel receiving plate 8 is aligned with the approach direction of the wheel 4, the wheel receiving plate 8 is elastically displaced by the pressing of the wheel 4, and the input arm 2 is moved by the wheel receiving plate 8. It is characterized in that it is pushed in the closing rotation direction. When the user of the bicycle parking facility carries the bicycle into the bicycle parking device and puts the front wheel 4 of the bicycle 3 on the wheel receiving plate 8 or hits the wheel receiving plate 8, The wheel receiving plate 8 is elastically displaced and pushes the input arm 2. Since the input arm 2 is pushed by the wheel 4 via the wheel receiving plate 8 in this manner, the lever arm 1 is rotated in the closing direction, and the restraining arm 5 holds the wheel 4 from its side. When the lever arm 1 rotates to the restraining position of the wheel 4 in this manner, the lock mechanism 7 operates to lock the lever arm 1 at the restraining position. The wheel receiving plate 8 is arranged with a certain length along the direction of entry of the wheel 4. If the wheel receiving plate 8 is pushed by the wheel 4 at any position in the length direction, the wheel receiving plate 8 faces the input arm 2. Even if the wheel 4 does not stop at the correct position facing the input arm 2 accurately,
The input arm portion 2 is pushed as necessary and sufficiently by the elastically displaced wheel receiving plate 8. The wheel receiving plate 8 is typically constituted by a leaf spring having a fixed width and length, but may be constituted by a plate member supported by a spring member such as a coil spring or a leaf spring. In the illustrated embodiment, the bicycle parking device 9 is fixedly mounted on the floor 10 of a bicycle parking facility, and the bicycle parking lock device 11 of the present invention is The control box 13 is fixed to a side surface of the support 12 and is provided at an upper end of the support 12. The lever arms 1 are arranged in a pair on the left and right, and are mounted on a fixed base 15 by a vertical pivot shaft 14. Bicycle 3 that has moved on the floor 10
Moves on the approach slope 16 and then to the stop slope rail 17. Stop side slope rail 1
5, the lower side surface of the front wheel 4 is supported by the left and right guide frames 18 so as not to fall. When the wheel 4 falls on the stop-side slope rail 17 in this manner, the wheel receiving plate 8 is pushed by the wheel 4, and the lever arm 1 closes and rotates about the vertical pivot 14 to restrain the lever arm 1. The arm portion 5 holds the wheel 4 from both left and right sides. The vertical pivot 14 is passed through a shaft hole 19 at the corner of the intersection between the input arm 2 and the restraining arm 5, and the lever arm 1 is opened by a spring member such as a torsion coil spring and biased to rotate in the rotational direction. When the stopper shoulder 20 at the intersection corner engages with the recess 21 of the fixed base 15, the stopper 20 is held at the standby position indicated by the chain line in FIG. A lock lever 23, which is a main member of the lock mechanism 7 by a horizontal pivot 22, is provided on the fixed base 15 on both sides of the base of the lever arm 1. The lock lever 23 is
When the lever arm 1 rotates to the restraining position, the lever arm 1 is rotationally urged by a spring member such as a torsion coil spring so as to enter and engage behind the shoulder portion 20 of the lever arm 1. As described above, the tip portion 24 of the lock lever 23
Penetrates into the space between the shoulder 20 of the lever arm 1 and the front surface of the fixed base 15, the opening rotation of the lever arm 1 is firmly prevented, and the lever arm 1 is locked at the position where the wheel 4 is restrained. The release rotor 25 disposed between the tip portions 24 of the left and right lock levers 23 has a shaft portion 27 fitted in a receiving hole 26 of the fixed base 15, and the front end wing portion 28 is attached to the tip portion 24 of the lock lever 23. It is arranged to press. An operating lever 29 for releasing the lock mechanism 7 is fixed to the rear end of the shaft 27 that appears on the back side of the fixed base 15. The lock mechanism 7 is concealed by the front cover 30. When the user pays a predetermined fee in cash or a card in the control box 13 or certifies the use qualification with a user card, an unlock signal of the lock mechanism 7 is generated. The release signal enables the operation handle 31 of the control box 13 to be operated. By turning the operation handle 31 in a predetermined direction, the interlocking wire 32 connected to the shaft of the operation handle 31 moves the operation lever 29 in the release direction. Drive. The rotation of the operation lever 29 rotates the release rotor 25, and the front end wing portion 28 of the release rotor 25 pushes the distal end portion 24 of the lock lever 23. Therefore, the distal end portion 24 of the lock lever 23 is disengaged from the position where the distal end portion 24 is engaged with the shoulder portion 20 of the lever arm 1, and the lock of the lever arm 1 is released. Therefore, when the wheel 4 is moved in the take-out direction, the lever arm 1 is opened and rotated to the standby position when the restraining arm 5 is pressed against the side surface of the wheel 4. The bicycle parking lock device of the present invention can be applied not only to the front wheels but also to the rear wheels. Further, the installation position of the bicycle parking lock device is not limited to the side surface of the pillar of the bicycle parking device, but may be installed on another site, for example, on the floor of a bicycle parking facility.
