Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a movable slope for a parallel parking device.

[Prior art]

Conventionally, in a parallel parking system, a movable slope 1 as shown in Fig. 2 is installed on the pit floor surface, and when the cage 2 of the front row parking system is operated, it is flush with the pit floor surface as shown by the two-dot chain line. When a car enters or leaves the cage 3 of the rear parking device, one end of the movable slope 1 is lifted by the drive device to form a roadway, as shown by the solid line.

[Problem that the invention attempts to solve]

However, since this movable slope 1 is generally composed of a simple iron plate, when a car runs on this movable slope 1, the driver cannot directly check the left end (passenger seat side) of this slope. An inexperienced driver could cause a bicycle accident. Furthermore, even if the driver is an experienced driver, it is still dangerous to leave the garage in reverse.

The present invention was devised in view of the above points, and an object thereof is to provide a safe movable slope that is free from the risk of causing accidents such as derailment.

[Means for solving problems]

This invention features a movable slope that normally descends to the pit floor and rises when a car passes by.
A lever is provided on the side of the movable slope so that it can freely rotate in a vertical plane, and a rotatable roller is provided at the lower end of the lever that extends below the movable slope. It is constructed so that the lever is in a horizontal state in contact with the pit floor surface.

[Effect]

With the configuration as described above, the lever automatically rotates in accordance with the elevation and descent of the movable slope.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. In the figure, 10 is a movable slope whose one end is rotatably supported on the pit floor 11, the other end is connected to the tip of a plunger 12a such as a hydraulic device, and is raised and lowered by a drive device 12 consisting of a hydraulic device or the like. A parallelogram-shaped safety fence 20 is provided on the side surface of the movable slope 10. This safety fence 20 includes levers 21, 22, 23 and springs 24.
The lever 21 is connected to the left and right connecting parts 21.
a and 21b are rotatably supported by the upper ends of the levers 22 and 23, and the lower end of the lever 22 is pivoted to the side surface of the movable slope 10, while the bent portion 23a of the lever 23 has a bent shape on the side surface of the movable slope 10. A roller 23b is rotatably mounted on the lower end facing the pit floor 11, and a spring 24 connects the intermediate part of the lever 23 and the movable slope 10.
It has the function of keeping the lever 23 in an upright state in contact with the stopper 25, as shown in FIG. 1a.

With such a configuration, when operating the front row parking device, the drive device 12 is activated to retract the plunger 12a, and the movable slope 10
When the roller 2 at the lower end of the lever 23 is lowered,
3b is pressed against the pit floor 11, and the lever 23 rotates clockwise against the spring pressure of the spring 24, causing the lever 21 to be retracted to the side of the movable slope 10, as shown in FIG. 1b. In this way, the operation of the parking device can be prevented from being hindered, and when a car passes on the movable slope 10, the drive device 12 is operated in the opposite direction to extend the plunger 12a, and the movable slope 10 is moved. When the lever 23 is raised, the roller 23b at the tip of the lever 23 is released from the pit floor 11, and the lever 23 is rotated counterclockwise by the spring pressure of the spring 24, so the lever 23 is in an upright state and the safety fence 20 is in the first position. The state will be as shown in Figure a. Therefore, the driver of the vehicle can not only sufficiently check both ends of the movable slope 10, but also be able to physically prevent the vehicle from going off the rails.

Moreover, this safety fence 20 also serves as a handrail when the driver of the car walks on the movable slope when entering and exiting the rear parking device, ensuring safety for the users. It is something that

Such a safety fence 20 may be provided on both sides of the movable slope 10, or may be provided only on the passenger seat side of the automobile.

〔effect〕

As described above, according to the present invention, a parallelogram-shaped (not necessarily parallelogram-shaped) safety fence is provided on the side surface of the movable slope, and the safety fence itself is moved as the movable slope goes up and down. Because the standing and tilting operations are performed without using a special drive device, it is possible to obtain an extremely safe movable slope that does not interfere with the operation of the parking device and does not cause a car accident. .

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a movable slope that normally descends to the pit floor and rises when a car passes by, a lever is provided on the side of the movable slope so that it can freely rotate in a vertical plane. A rotatable roller is provided at the lower end of the lever that extends below the movable slope, and when the movable slope is lowered, the roller contacts the pit floor surface and the lever becomes horizontal. A movable slope in a parallel parking device characterized by being configured as follows. (2) One end of a second lever is rotatably connected to the upper end of the lever, one end of a third lever is rotatably connected to the other end of the second lever, and the third lever is rotatably connected to the upper end of the lever. A movable slope in a parallel parking system according to claim 1, wherein the other end of the lever is rotatably attached to a side surface of the movable slope to constitute a safety fence that also serves as a handrail.
