Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a movable step for a vertical circulation mechanical multilevel parking system installed in tandem.

[Prior art]

Conventionally, parallel parking devices 1 installed in the valleys of buildings in large cities often face the road 2 on both sides in the direction of vehicle entry into the parking facility, as shown in FIG. All of the parking devices each have at least one cage cutout so that a motor vehicle 3 can pass through the parking facility.

That is, as shown in FIG. 3, for example, movable decks 13 and 14 are provided on the ground floor 12 near entrances 10 and 11 of the parking facility, and movable decks 13 and 14 are provided near the communication opening 17 between the front row parking device 15 and the rear row parking device 16. A seesaw-shaped movable deck 18 is provided on the ground floor 12 of
6 can be loaded into or taken out of the cage 16a as appropriate.

[Problem that the invention attempts to solve]

However, especially when the movable deck 18 of the communication port 17 has a mere seesaw shape, there are the following drawbacks.

That is, the cage 15 of the front row parking device 15 happens to be
When a is a parking cage and the cage 16a of the rear parking device 16 is an empty cage and the unloading operation and the reloading operation overlap, when the movable deck is in the state shown by the solid line in Fig. 3 or the state shown by the two-dot chain line. In any case, if the cage 15a of the front row parking device 15
If a vehicle stored in the parking lot is attempted to exit toward the exit 11, the vehicle will either fall onto the movable step 18 or collide with the rear cage 16a, causing an accident. This is because the car in the back row is empty, so the driver who is parking in the front row mistakenly causes the driver to pull out, thinking that he or she can move forward.

The present invention has been developed in view of the above points, and it is an object of the present invention to provide a movable step that does not cause damage to the vehicle or parking device even if the driver accidentally moves to the exit operation.

[Means for solving problems]

The present invention provides at least a movable step in a passageway connecting a front row parking device and a rear row parking device, in which a car enters and leaves the cage of the front row parking device or the cage of the rear row parking device through the movable step. It is composed of a first movable step and a second movable step, and supports one side of the first movable step on the front row parking device side and one side of the second movable step on the rear row parking device side so as to be able to move up and down. The other side of the first movable step opposite to the front row parking device and the other side of the second movable step opposite to the rear row parking device are rotatably supported.

[Effect]

With the above configuration, even if the vehicle is moved by mistake, an accident such as falling into a pit can be avoided.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 is a plan view of the movable step device according to the present invention, FIG. 4 is a view taken along the - line in FIG. 1, and FIG. 5 is a view taken along the - line in FIG. a base, 23, 2, on which an identical drive device 21, 21' consisting of a cylinder is installed;
3' is a movable step according to the present invention, and a base 20
Step support stand 2 erected near both ends of the center of
5 via a hinge 25a so as to be rotatable symmetrically, and the movable steps 23 and 23' are arranged so that one side of the movable steps 23 and 23' are adjacent to each other and face each other. A lever 26 is rotatably attached to the tip of the rod 21a of the drive device 21, and both ends of the lever 26 are fixed to a shaft 28 rotatably supported by the base 20 via a bearing 27. Near the bearing 27 of this shaft 28 is a constantly movable step 23 at the tip.
A lever 30 having a roller 29 in contact with the back side of the lever 30 is fixed. Reference numeral 31 designates a bracket provided on the base 20, and when the lever 30 is rotated clockwise by a predetermined angle in FIG. 4, the protrusion 30a of the lever 30 engages with this bracket 31 and functions as a stopper. Reference numeral 32 designates a limit switch provided on the bracket 31, which is activated immediately before the projection 30a of the lever 30 comes into contact with the bracket 31. 33 is base 2
A limit switch located at 0 is activated when the step is lowered by a predetermined amount. In the above explanation, the structure of the movable step 23 is described in detail, but the structure of the movable step 23' is exactly the same except that it is opposite, so those with the same functions are denoted by the same reference numeral with a ``''. A detailed explanation of the configuration will be omitted.

Next, the operation of the device of the present invention will be explained. First, while the parking device is being operated or when the cage cutout is stopped at the entrance/exit 10 or 11, for example, the rods 21a, 21'a of the drive devices 21, 21' are in an extended state, respectively. Therefore, as shown in Figure 4, lever 2
6. The shaft 28 and lever 30 are integrally rotated counterclockwise, and the lever 26', shaft 28', and lever 30' are integrally rotated clockwise as shown in FIG. It is assumed that the parking equipment sides 23 and 23' are in the state shown in FIG. 6a, in contact with the base 20.

Therefore, when the cage of the parking device (which may be either a parking cage or an empty cage) lands and stops at the entrance/exit 10 or 11, the drive device 21 or 21' of the parking device on the side where the parking device stopped is activated to move the parking device. 21a or 21'a, and if it is the drive device 21, the lever 26, shaft 28, and lever 30 are integrally rotated clockwise, and the movable step 23 is moved through the roller 29 at the tip of the lever 30. Lift up the front row parking device side of the
When the protrusion 30a contacts the limit switch 32, the drive device 21 is stopped so that the stopper 31 supports all the weight applied to the lever 30.

On the other hand, if the drive device 21' operates, the lever 2
6', shaft 28', and lever 30' are rotated counterclockwise in conjunction with each other to similarly lift the movable step 23'. Accordingly, the movable step device according to the invention may in each case be schematically illustrated in FIGS. 6a, b,
This means that four states, c and d, can be created.

That is, in the state shown in FIG. 6b, the movable step 2
3, 23' to the cage 1 of the front row parking device 15.
5a, and in the state shown in FIG. 6c, the motor vehicle can now freely enter and exit the cage 16a of the rear parking device 16 through the movable steps 23, 23', and in the state shown in FIG. 6d. , if one of the cages is empty, the movable step 2
Even if an attempt is made to take the car out of the garage through 3, 23', the car will not fall into the pit or collide with the cage.

Normally, even when the parking device is operated, there is no risk of the cages colliding with the movable steps 23, 23', so there is no need to intentionally bring the parking device into the state shown in FIG. 6a before driving. This is convenient when a car passes through the parking device.

In the above explanation, the movable steps 23 and 23' are supported separately and rotatably by separate shafts, but in this case, for example, as shown in FIG. It may also support movable steps 42, 42' separated by 41.

[Effect of idea]

As described above, according to the present invention, the movable step connecting the front row parking device and the rear row parking device is divided into two sections with at least one side facing each other, and the opposing portions are rotatably supported, so that it can be adjusted with or without a cage. Since the degree of inclination of each movable step is changed accordingly, there is no risk of causing an accident even if the vehicle is operated incorrectly when entering or exiting the garage.
