Description

  The present invention relates to a bicycle parking device with a slide prevention mechanism that prevents a sliding bicycle parking rack of the bicycle parking device from inadvertently sliding when a bicycle is placed.

  2. Description of the Related Art Conventionally, a bicycle parking apparatus is widely used in which a bicycle parking rack on which a bicycle is placed is slidable along a rail in order to effectively use a parking space. In such a bicycle parking device, in a state where the bicycle is placed or in an empty state, the bicycle can be slid so that more bicycles can be parked so that the interval between the racks can be reduced. Is configured so that the bicycle can be safely inserted and removed without being slidable (for example, Patent Document 1).

  In this bicycle parking apparatus, when a bicycle is put on the front wheel, if the front pedal depresses a stopper pedal provided at the entrance of the bicycle parking rack, the stopper works to prevent the parking rack from sliding, and the rear wheel continues. When the stopper pedal is depressed, the stopper is released and the parking rack can be slid. Similarly, when the bicycle is lowered, the parking rack cannot slide when the rear wheel depresses the stopper pedal, and when the front wheel subsequently depresses the stopper pedal, the stopper is released and the parking rack can be slid.

JP 2006-347362 A

  However, in the bicycle parking device of Patent Document 1, when the bicycle is turned back with only the front wheel on the bicycle parking rack, the stopper remains working, so that the bicycle can be slid even though the bicycle parking rack is empty. In addition, there was a problem that if you try to park the bicycle again, if you put the front wheel on the parking rack again, the stopper will be released and the parking rack will slide and you can not park safely .

  The present invention has been made in view of the above problems, and even if the bicycle is turned back with only the front wheel on the bicycle parking rack, the bicycle parking rack can be made slidable. An object of the present invention is to provide a bicycle parking device with a slide prevention mechanism that prevents a bicycle parking rack from sliding during bicycle parking even when attempting to park a bicycle.

  The invention made in order to solve the above-mentioned problems comprises a rail, a parking rack that slides along the rail, and a slide prevention mechanism that prevents the parking rack from sliding, and the parking rack has a front side. The front wheel housing part, and a rear wheel housing part for guiding a front wheel of a bicycle parked to the front wheel housing part continuously to the rear side of the front wheel housing part and housing the rear wheel, the slide prevention mechanism A fixed member fixed to the parking rack, a sliding member supported so as to be slidable in one direction and the other direction opposite to the one direction with respect to the fixed member, and the sliding member A lock pin that is supported so as to be slidable in the one direction and the other direction relative to the rail, a restraining member that restrains the lock pin fixed to the rail and slid in the one direction, and the front wheel housing portion. Bicycle housed A lock pin driving means that is operated by a wheel to shift to the front wheel receiving position and slides the lock pin in the other direction and is urged to return to the front wheel non-receiving position when the front wheel escapes from the front wheel receiving portion. And provided between the sliding member and the lock pin, for urging the lock pin relative to the sliding member in the one direction and returning the lock pin driving means to the front wheel non-accommodating posture. Lock pin urging means for sliding the lock pin relative to the sliding member in the one direction, and provided in the rear wheel housing portion, the sliding is made by shifting to a parking position by the weight of a bicycle. A sliding member driving means that slides the moving member in the one direction and is urged to return to an empty vehicle posture when the weight of the bicycle is released; and provided between the fixed member and the sliding member. Urging the sliding member in the other direction, and sliding member urging means for sliding the sliding member in the other direction when the sliding member driving means returns to the empty position. The sliding member driving means is a bicycle parking device with a slide prevention mechanism having a length that allows the front and rear wheels of the bicycle to be placed simultaneously.

Thus, in the bicycle parking apparatus with a slide prevention mechanism of the present invention, when the bicycle to be parked is placed on the sliding member driving means of the rear wheel housing portion, the sliding member driving means moves to the parking posture and slides. The moving member is slid in one direction among one direction and the other direction opposite to the one direction. In the following description, assuming that the forward direction is the one direction and the backward direction is the other direction, the lock pin is supported by the sliding member at this time, so that the lock pin slides forward together with the sliding member. The lock pin that has slid forward is restrained by the restraining member, and sliding along the rail of the bicycle parking rack is prevented. Since the sliding member driving means has a length that allows the front and rear wheels of the bicycle to be placed simultaneously, the sliding member driving means remains parked by the rear wheels even after the front wheel of the bicycle leaves the sliding member driving means. The sliding member is maintained at the position slid forward. When the front wheel of the bicycle is housed in the front wheel housing portion, the lock pin driving means shifts to the front wheel housing posture by the front wheel of the bicycle and slides the lock pin backward against the lock pin urging means. At this time, since the sliding member is maintained at the position slid forward by the sliding member driving means maintained in the parking posture by the rear wheel of the bicycle, only the lock pin slides backward. Thus, the lock pin is released from the restraining member, and the parking rack can be slid. From this state, when the front wheel of the bicycle is withdrawn from the front wheel housing portion to the rear wheel housing portion in order to lower the parked bicycle, the lock pin driving means returns to the front wheel non-accommodating posture and the lock pin slides forward. Let Then, the lock pin is restrained by the restraining member, and the parking rack is prevented from sliding. At this time, since the sliding member driving means has a length that allows the front and rear wheels of the bicycle to be placed simultaneously, the front wheel rides on the sliding member driving means before the rear wheel of the bicycle leaves the sliding member driving means. Therefore, the sliding member driving means is maintained in the parking position as it is. Then, when the front wheel moves backward and leaves the sliding member driving means, the sliding member driving means returns to the idle position and the sliding member slides backward by the sliding member urging means. Then, the lock pin is released from the restraining member, and the parking rack can be slid.
Then, if the case where only the front wheel is placed on the parking rack and turned back, which is the subject of the present invention, will be described, first, when the front wheel is placed on the parking rack, the sliding member driving means moves to the parking posture. The sliding member and the lock pin integrally slide forward, and the lock pin is restrained by the restraining member, thereby preventing the parking rack from sliding. After that, when the bicycle is moved backward and the front wheel of the bicycle is lowered from the front end of the sliding member driving means, the sliding member driving means returns to the empty position and the sliding member and the lock pin are moved backward integrally to The restraint from the restraining member is released. Further, when the front wheel is placed on the sliding member driving means of the parking rack in order to park the bicycle again, the sliding member driving means moves again to the parking posture and the sliding member and the lock pin Since the vehicle is slid forward, sliding of the parking rack is prevented.

  As described above, according to the parking device with a slide prevention mechanism of the present invention, the parking rack slides even when the bicycle is turned back and the front wheel is lowered from the parking rack with only the front wheel placed on the parking rack. The parking rack can be prevented from being left in a locked state, and the parking rack can be prevented from sliding even during the subsequent parking.

Between the sliding member driving means 37 and the rear wheel accommodating portion 22, a spiral spring 6 for biasing the sliding member driving means 37 to the empty wheel position is disposed as shown in FIG.

  Next, the effect | action of the slide prevention mechanism 3 of the bicycle parking apparatus 100 which concerns on 1st Embodiment is demonstrated. FIG. 2 shows a main part of the bicycle parking apparatus 100 in an empty state. As shown in FIG. 2 (a), the parking device 100 waits for the front wheel non-accommodating posture with the lock pin driving means 35 urged upward by the urging means 35c as shown in FIG. 2 (a). ), The sliding member driving means 37 is biased upward and rearward by the spiral spring 6 and stands by in an empty vehicle posture. At this time, the guide member 37 c of the sliding member driving means 37 is located above the long hole 22 a of the rear wheel housing portion 22.

  In this state, when the bicycle is to be parked on the bicycle parking device 100, when the front wheel F of the bicycle A is inserted into the entrance 22c at the rear end of the rear wheel housing portion 22, the front wheel F is slid as shown in FIG. Riding on the moving member driving means 37, the sliding member driving means 37 is pushed down while pushing down the spiral spring 6 by its own weight. At this time, the sliding member driving means 37 moves forward and downward (in the direction of the arrow in FIG. 3B) by the action of the guide member 37c following the long hole 22a. Accordingly, the operation piece 37b fixed below the sliding member driving means 37 presses the rear end surface of the sliding member 32 and slides the sliding member 32 forward (to the left in FIG. 3B). Move. Then, since the lock pin 33 is supported by the sliding member 32, it moves forward together with the sliding member 32 and penetrates into the lock pin locking hole 34 a of the restraining member 34. When the lock pin 33 abuts against the restraining member 34 between the adjacent lock pin locking holes 34a, 34a, the parking rack 2 slides slightly along the rail 1, and the lock pin 33 is locked to the lock pin locking hole 34a. Intrude into. Thus, it is possible to prevent the parking rack 2 from sliding relative to the rail 1 while the front wheel F and the rear wheel R pass through the rear wheel housing portion 22. In FIG. 3, the reference symbol F (R) for the wheels (illustrated by phantom lines) mounted on the sliding member driving means 37 is the front wheel F only on the sliding member driving means 37 during parking. In addition to the case where it is placed, the rear wheel R may also be placed together.

When the front wheel F has finished passing through the rear wheel housing part 22 and the front wheel F is housed in the front wheel housing part 21, the front wheel F is a horizontal bar of the lock pin driving means 35 as shown by an arrow in FIG. When the lock pin driving means 35 is pushed down from the front wheel non-accommodating posture (the posture shown by the phantom line in FIG. 4A) to the front wheel housing posture (the posture shown by the solid line in FIG. 4A) by contacting the portion 35b Then, the lock pin 33 is pulled backward (to the right in FIG. 4B) via the wire 39, and the lock pin 33 escapes from the lock pin engaging hole 34a.
Thus, the bicycle parking rack 2 can slide along the rail 1 while the bicycle F is parked on the bicycle parking rack 2.

  Here, the sliding member driving means 37 has such a length that the front wheel F and the rear wheel R of the bicycle A can be placed at the same time, that is, the front wheel F extends from the front end portion 37 d of the sliding member driving means 37. The length is set such that the rear wheel R rides on the rear end portion 37c before leaving. For this reason, after the front wheel F leaves the sliding member driving means 37, the sliding member driving means 37 remains in the rear wheel until it is accommodated in the front wheel accommodating portion 21 and the lock pin driving means 35 is shifted to the front wheel accommodating posture. Since the bicycle A receives its own weight through the wheel R and is maintained in the parking posture, the lock pin 33 remains locked in the lock pin locking hole 34a at the front position, and the parking rack 2 slides. Will continue to be prevented.

  Next, the action of the slide prevention mechanism 3 when the bicycle A is lowered from the parking rack 2 will be described. When the bicycle A is retracted along the parking rack 2 and the front wheel F escapes from the front wheel housing portion 21, the anti-slide mechanism 3 is again in the state shown in FIG. That is, as shown in FIG. 3A, the lock pin driving means 35 is released from its own weight of the front wheel F and returned to the front wheel non-accommodating posture by the urging means 35c. Then, the force by which the wire 39 pulls the lock pin 33 backward (rightward in FIG. 3B) is released, and the lock pin 33 is moved forward (leftward in FIG. 3B) by the lock pin urging means 36. To the lock pin engaging hole 34a of the restraining member 34. Thus, sliding of the bicycle parking rack 2 with respect to the rail 1 is prevented while the bicycle F moves backward along the rear wheel housing portion 22.

  Here, the sliding member driving means 37 has such a length that the front wheel F and the rear wheel R of the bicycle A can be placed simultaneously, that is, the rear wheel R is detached from the rear end portion 37 c of the sliding member driving means 37. The length is set such that the front wheel F rides on the front end portion 37d before the sliding wheel driving means 37 is bicycled via the front wheel F even after the rear wheel R leaves the sliding member driving means 37. Since the bicycle parking posture is maintained under the weight of A, the lock pin 33 remains locked to the lock pin locking hole 34a at the front side position, and continuously prevents the parking rack 2 from sliding. .

  After that, when the front wheel F is retracted from the entrance 22c of the rear wheel rack housing portion 22 after the rear wheel R and separated from the sliding member driving means 37, the slide preventing mechanism 3 is again in the state shown in FIG. . That is, the sliding member driving means 37 is released from the dead weight of the bicycle A, and returns to the empty vehicle posture by the urging force of the spiral spring 6, and the operation piece 37b moves backward. The sliding member 32 is released from the force pushed forward by the operation piece 37, and slides backward (to the right in FIG. 2B) by the sliding member urging means 38 with the lock pin 33. Thus, the lock pin 33 comes out of the lock pin engaging hole 34a of the restraining member 34, and the parking rack 2 can slide along the rail 1 when the vehicle is empty.

  Next, a case where only the front wheel F is placed on the parking rack 2 and turned back will be described. First, when the front wheel F of the bicycle A is placed on the parking rack 2, the slide prevention mechanism 3 is in the state shown in FIG. That is, as shown in FIG. 3B, the sliding member driving means 37 shifts to the parking position, and the sliding member 32 and the lock pin 33 are integrally moved forward (leftward in FIG. 3B). The lock pin 33 is restrained by the lock pin engaging hole 34 a of the restraining member 34. Thus, sliding of the bicycle parking rack 2 with respect to the rail 1 is prevented.

  Thereafter, parking is stopped and the bicycle A is moved backward, and when the front wheel F of the bicycle A is detached from the rear end portion 37c of the sliding member driving means 37, the slide prevention mechanism 3 is shown in FIGS. Return to state. That is, as shown in FIG. 2 (b), the sliding member driving means 37 returns to the empty position and the sliding member 32 and the lock pin 33 are retracted integrally, and the lock pin 33 is locked to the lock pin engaging hole 34a. 2 is released, the restraint from the restraining member 34 is released, and the state returns to the state of FIG. Thus, even when only the front wheel F is placed on the parking rack 2 and parking is stopped and the bicycle A is turned back, the empty parking rack 2 can slide along the rail 1. Since the anti-slide mechanism 3 has returned to the state shown in FIG. 2, when the bicycle A is parked again, the above-described first time when the bicycle A is parked for the first time, Similarly, the parking rack 2 is prevented from sliding during parking.
