Description

  The present invention relates to a bicycle parking apparatus.

  Recently, in bicycle parking lots of supermarkets, bicycle parking lots around stations, or bicycle parking lots of condominiums, bicycle parking devices that store bicycles up and down for the purpose of storing as many bicycles as possible in a limited space are available. Is provided.

  As such a bicycle parking device, a bicycle mount on which a bicycle is placed is provided in two upper and lower stages with a phase shifted left and right in a plan view, and when the upper bicycle mount is used, In many cases, the bicycle is lowered and placed on a bicycle mount and then raised again to be stored.

  When such an upper bicycle mount is raised or lowered, the force for raising and lowering is greatly different depending on the weight of the bicycle when the bicycle is placed and when the bicycle is not placed. For this reason, even when a bicycle is placed, there is a column provided with a balance weight (counter weight) so that it can be lifted and lowered with a light force as in the case of empty (for example, see Patent Document 1). And with this type of counterweight, when the bicycle is not loaded, the weight of the counterweight will cause the bicycle platform to rise momentarily and be dangerous. Is provided with an attaching / detaching mechanism for switching so that the counterweight does not act.

By the way, in the above-mentioned conventional bicycle parking device, if the empty bicycle mount is lowered, it takes a space and becomes an obstacle, so that even when empty, the bicycle mount is moved upward as in the case where the bicycle is placed. It is necessary to raise and store.
However, even in the case of an empty bicycle mount, as in the case where the bicycle is placed, the operation for raising and storing the bicycle and the operation for switching the attachment / detachment mechanism are troublesome, and the ease of use of the bicycle parking apparatus becomes poor.

  In view of this, the inventors of the present application have previously proposed a flip-up type bicycle parking apparatus that is configured to be flipped up and stored when the bicycle mount is empty (see Patent Document 2). This bicycle parking device pivotally supports a base end side portion of a bicycle mount on a support member so that the bicycle mount can rotate, and the bicycle stand is in a parking standby position where the bicycle is placed on the bicycle mount; When this bicycle mount is empty, it can be swung to a flip-up posture position in which the distal end portion is flipped upward with the proximal end portion as a fulcrum. In this bicycle parking device, when the bicycle mount is empty, the base end portion of the bicycle mount is used as a fulcrum, and the tip end portion is flipped upward to convert it into a flip-up posture position. An empty bicycle mount can be stored in a small space with a simple structure, and the ease of use of the bicycle parking device is improved.

A base end side portion of the bicycle mount is pivotally supported by the slider. Further, the bicycle stand is moved from the parking stand-by position to the bicycle stand-by posture position where the bicycle is placed on the bicycle stand, the storage position where the bicycle is stored above, and the storage position. It is configured to be able to move up and down to a parking posture position that is positioned slightly below, and when the bicycle mount is in the parking posture position, the distal end portion is flipped upward with the base end portion as a fulcrum. It is configured to be swingable so as to be in the flip-up posture position. And an urging means for urging the bicycle pedestal so that the bicycle pedestal is lifted up from the parking posture position, and the urging unit urges the bicycle gantry when the bicycle gantry is in the parking standby posture position. While the bicycle parking stand is held in the parking posture position against the biasing force of the means, when the bicycle stand is in the parking posture position, the bicycle stand is raised to the raised posture position by the biasing force of the biasing means. Posture conversion means for allowing conversion.

  Due to this specific matter, the bicycle stand is held at the parking stand-by posture position by the posture changing means against the biasing force of the biasing means at the bicycle stand-by posture position where the bicycle is placed. Placed smoothly. The bicycle mount on which the bicycle is placed in this parking standby posture position is raised along the lifting column by the slider and stored upward. Then, the bicycle mount stored above is lowered to a parking posture position slightly below the parking standby posture position, and when the bicycle is lowered at this parking posture position and the bicycle mount becomes empty, the posture The conversion means allows conversion of the bicycle mount to the flip-up posture position by the urging force of the urging means. As a result, the empty bicycle mount is automatically converted from the parking posture position to the flip-up posture position by the biasing force of the biasing means, and the empty bicycle mount is moved from the parking posture to the flip-up posture position. The user never forgets to operate, and the empty bicycle mount does not get in the way.

  Further, the posture changing means includes an engagement pin provided on the bicycle mount, an engagement position provided on the slider, and an engagement position that engages with the engagement pin, and a non-engagement position that does not engage with the engagement pin. An engagement member that is converted into a bicycle parking position, and the engagement member is switched to the engagement position when the bicycle mount is in the parking position, while the engagement is switched when the bicycle mount is in the parking position. Preferably, switching means for switching the combined member to the non-engaging position is provided.

  In this case, the switching means of the posture converting means switches the engaging member to the engaging position and engages the engaging pin when the bicycle mount is in the parking standby posture position, thereby While holding the bicycle stand in the parking standby position against the urging force, when the empty bicycle mount is in the parking position, the engaging member is switched to the non-engaging position and the engaging pin is not engaged. By being engaged, conversion from the bicycle parking posture position to the flip-up posture position of the bicycle mount by the urging force of the urging means is allowed. As a result, the empty bicycle mount is automatically converted from the parking posture position to the flip-up posture position by the urging force of the urging means, with a simple configuration that only switches the engagement member with respect to the engagement pin. It is possible to prevent the user from forgetting to operate the empty bicycle mount in the flip-up posture position, and to reliably convert the empty bicycle mount from the parking posture position to the flip-up posture position.

  In short, when the bicycle mount is in the parking standby posture position, the bicycle mount is held in the parking standby posture position against the biasing force of the biasing means, while being lowered from the upper storage position and parked. When the bicycle mount is empty at the wheel position, the bicycle mount is emptied by allowing conversion of the bicycle mount from the parking position to the flip-up position by the biasing force of the biasing means. Can be automatically converted from the parking posture position to the flip-up posture position by the biasing force of the biasing means, and the user forgets to forget to operate the flip-up posture position of the empty bicycle stand, and the empty bicycle stand Can be surely converted into the flip-up posture position without obstructing.
