Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable step for a parallel parking system.

[Prior art]

Conventionally, in a parallel parking system, a movable slope 1 as shown in FIG. 2 is installed on a pit floor 2.
When the gauge 3 of the front row parking device is operated, it becomes flush with the pit floor surface 2 as shown by the two-dot chain line,
When a car is carried into and out of the gauge 4 of the rear parking device, one end of the movable slope 1 is lifted by a drive device (not shown) to form a roadway, as shown by the solid line.

[Problem that the invention seeks to solve]

However, since such a movable slope 1 has a mechanism in which one end is raised and lowered between the levels of the landing 5 and the pit floor 2, especially if the chain suspending the gauge 3 of the front row parking device stretches due to aging, There was a difference in level between the floor surface of the gauge 3 and the floor surface of the landing hall 5, which could impede the movement of vehicles into and out of the garage. In addition, since the speed of the cage is controlled, the speed control does not always go well and the same problem as mentioned above occurs if the landing level is out of order, and you have to take the trouble to adjust the level each time, making it difficult to operate the cage. There was also the fear that efficiency would be significantly reduced.

The present invention has been made in view of the above points, and includes a movable step that can be easily adjusted even if the landing level of the gauge deviates for some reason, and can also be used for loading and unloading the gauge into and out of the rear parking system. The purpose is to provide.

[Means for solving problems]

In the present invention, a movable step is provided in a pit of a front row parking device so that a car can be carried into and out of a rear row parking device, and the movable step is separated from a first movable step and a second movable step. The first movable step has one end rotatably supported on the rear parking device side, the second movable step has one end rotatably supported on the entrance/exit side, and the other free end of the first movable step is rotatably supported. The other free end of the second movable step has a recess on the upper surface, and the other free end of the second movable step has a recess on the lower surface and is arranged such that the recesses contact and separate each other. The movable step is disposed at a position where the vehicle can be carried in and taken out, and a drive mechanism is provided below the movable step for raising and lowering the other free ends of the first and second movable steps.

[Effect]

With the above-mentioned structure, the degree of elevation of the other free ends of the first movable step and the second movable step is adjusted to create a state in which it is easy to carry in and out of the vehicle.
