Abstract

PURPOSE:To secure safety and reliability at low cost by rotating an auxiliary floor plate always placed in an erected condition by being energized by a spring cylinder to a horizontal position by operation of a cam when an elevator arrives. CONSTITUTION:An auxiliary floor plate 30 is put always in an erected condition by being energized by a spring cylinder 35. At this time, when an elevator 10 is raised from the lower part of a pit 20, the auxiliary floor plate 30 is pushed upward by a roller 16 through a cam arm 33, and escapes elastically outward slightly temporarily, and allows ascension of the elevator 10. Next, when the elevator 10 is lowered slightly, the roller 16 on the tip of a bracket 15 projecting from the side surface comes into contact with a cam 34, and pushes the cam 34 down while rolling, and the auxiliary floor plate 30 is rotated to a horizontal position. In this way, only when the elevator 10 arrives at respective entrance and exit floors, the auxiliary floor plate 30 is rotated automatically to the horizontal position, and blocks up clearance between it and the elevator 10, and except that, it is rotated to a vertical position, and acts as an invasion preventive fence.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary floor board structure for getting on and off a vehicle in a three-dimensional parking lot with an elevator.

[0002]

2. Description of the Related Art In a multi-storey parking lot with an elevator, between the pallet on the elevator reaching the floor of the elevator door and the floor of the entrance / exit, in order to smoothly raise and lower the elevator, a slight horizontal direction is required. A clearance is provided. Although this clearance is necessary, children and elderly vehicle occupants may get stuck in it, so it is blocked by an auxiliary floorboard. This auxiliary floor plate is actuated by an auxiliary floor drive means such as an electric power cylinder so as to be horizontal when the elevator is reaching and to close the play space and to stand up after rising.

[0003]

However, the operation of such a conventional auxiliary floorboard has the following problems. (1) A sensor such as a limit switch for confirming the elevator position is required. (2) Position adjustment and inspection of each sensor is required. (3) Stroke adjustment and inspection of the driving means are required. (4) Synchronous operation of the four auxiliary floor boards around the vehicle mounting pallet is required. (5) In addition to the relatively high initial cost of the driving means and sensors, the running cost is also high.

The present invention has been proposed in view of such circumstances, and the auxiliary floor board is operated by utilizing the lifting force and spring force of the elevator, so that the auxiliary floor plate is automatically operated as the elevator is moved up and down. , Only when the elevator arrives, rotate to the horizontal position to close the gap with the elevator, and at other times, rotate to the vertical position to act as an intrusion prevention fence Simple structure, low cost and safe It is an object of the present invention to provide an auxiliary floor structure for vehicle entry / exit of a multi-story parking lot with an elevator, which is highly reliable and reliable.

[0005]

To this end, the present invention is provided for mounting a vehicle on an elevator by attaching at least one side of a rectangular opening of an elevator pit formed on a floor surface of a vehicle entrance floor of a multi-story parking lot with an elevator. In a rectangular movable auxiliary floor plate connected by a hinge so as to be able to move up and down by a hinge so as to substantially close the horizontal gap with the pallet, both ends are supported between the auxiliary floor plate and the inner wall of the elevator pit. An urging means for elastically urging in the upright direction, a cam drive arm protruding from the outer lower end portion of the elevator and abutting against a cam described later each time the elevator is moved up and down to rotate the cam, and an auxiliary floor plate. When the elevator is lifted up and down, the auxiliary floor plate passes upward and downward against the elastic force of the biasing means when the elevator moves up and down, and when the elevator stops, the auxiliary floor plate is in a horizontal position. Characterized in that comprising a moving cam.

[0006]

According to this structure, the auxiliary floor plate is tilted at least at one side edge of the rectangular elevator opening on the floor of the entrance / exit of the vehicle through the hinge so that the auxiliary floor plate can be leveled up to the vehicle mounting pallet on the elevator. It is designed to close the gap in the direction. The auxiliary floor plate is always in an upright posture by the elastic biasing means, and when the elevator is rising from the lower part of the pit, the auxiliary floor plate temporarily comes in contact with the elevator side cam drive arm and the auxiliary floor plate side cam. The upper passage of the elevator is allowed by turning slightly outward to escape. Similarly, when the elevator comes down from the upper part of the pit, the auxiliary floor plate temporarily turns slightly inward due to the contact between the cam driving arm and the cam to allow the elevator to pass downward. At that time, when the elevator stops at the stop floor, the auxiliary floor plate becomes horizontal due to the interaction between the cam driving arm and the cam, and the horizontal clearance with the pallet can be automatically and reliably closed.
