Description

  The present invention relates to a fall prevention device and a multi-story parking device that prevent a vehicle from falling in a multi-story parking lot.

  2. Description of the Related Art Conventionally, in order to park more vehicles in a limited site, three-dimensional parking apparatuses that three-dimensionally park vehicles by raising and lowering a chassis are widely used. In this three-dimensional parking apparatus, there has been proposed a fall prevention apparatus that prevents the vehicle from falling from the chassis when the chassis is raised or lowered or during parking.

  For example, in the parking equipment gate fall prevention device described in Patent Document 1, a fall prevention lever that pivots to the gate fall prevention position by the biasing force of a spring is pivotally mounted at an appropriate position on the frame side of the parking equipment to lower the gate. Sometimes a solenoid is provided to avoid the fall prevention lever from being allowed to pass against the biasing force of the spring.

  Further, in the pallet drop prevention device described in Patent Document 2, the pallet receiving member reaches the protruding position by operating the protruding and lifting operations of the pallet receiving member by the biasing force of the pair of spring members and the force of the electromagnetic solenoid. The sound at the time of making is reduced, and the pallet receiving member is reliably started toward the protruding position.

Further, in a conventional multi-story parking lot, after the vehicle is parked on the raised chassis, the driver gets down to the ground using the stairs provided in the parking facility.

  However, in the above-described conventional fall prevention devices described in Patent Documents 1 and 2, a solenoid is provided to operate the fall prevention lever and the pallet receiving member, and it is necessary to secure a driving power source for the solenoid. There is. For this reason, in addition to the power for raising and lowering the chassis, extra power is required to operate the fall prevention mechanism, and there is a problem that the running cost of the three-dimensional parking apparatus is increased. Moreover, since it is also necessary to provide power supply equipment for supplying power to the fall prevention device, there is a problem that the installation cost of the multi-story parking device increases. Furthermore, in the conventional fall prevention device, when releasing the fall prevention function, an operation to once release the load on the pallet side is necessary, and there is also a problem of placing a burden on the function on the side of the three-dimensional parking device. .

  Also, in the conventional multistory parking lot, the stair that goes up and down with respect to the pallet is fixed, so in the unmonitored situation such as when the manager is absent, there is a problem such as mischief by being invaded by a third party. There is also a problem that it may occur and the reliability of the user with respect to the multilevel parking lot is impaired.

  The present invention has been made in view of the above points, and has a fall prevention function that prevents the chassis from falling by a one-way mechanism that interlocks with the operation when the chassis is raised and lowered, without requiring a power source for supplying driving force. An object of the present invention is to provide a fall prevention device and a three-dimensional parking device that realizes an automatic release staircase function that releases a staircase function when it is unnecessary.
