Description

  The present invention relates to a door device provided at a vehicle entrance of a mechanical parking device.

  A mechanical parking device is a facility in which a mechanical device is arranged in a building built on the ground or in a space formed in the basement to store a large number of vehicles in three dimensions, such as an elevator type, a vertical circulation type, a horizontal circulation type, Various systems such as a plane reciprocating system are used. In any of these types of mechanical parking devices, the vehicle is provided with a loading / unloading unit for getting into the machine device, and this loading / unloading unit is provided with a door, and the mechanical device is arranged except when the vehicle is loaded / unloaded. The inside and the outside are cut off.

The doors are roughly classified into a method in which the door opens and closes in the vertical direction and a method in which the door opens and closes in the left-right direction, which is driven by an electric motor or the like. Among these, for doors that open and close in the left-right direction, convex or concave guide rails are laid on the floor to guide the lower part of the door body, and a part of the door body engages with these guide rails. To be guided. For example, Patent Literature 1 describes a door configuration using a concave guide rail, and Patent Literature 2 describes a door configuration using a convex guide rail.
JP 63-138076 A (FIG. 7) JP-A-7-259422 (FIG. 2)

  However, the door using such a lower guide rail has the following problems. First, in the case of a concave guide rail, foreign matter such as dust is likely to enter the groove, and the groove must always be inspected and removed. Moreover, when solid objects, such as a stone, are stepped on by a vehicle and are firmly pinched in a groove | channel, an effort is required in order to remove this.

  On the other hand, in the case of a convex guide rail, since there is no groove, there is no problem as described above. However, since the height of the guide rail protrudes about 20 mm from the height of the floor, noise occurs when the vehicle passes. And the vehicle also vibrates, causing the vehicle driver to feel uncomfortable or uneasy. Further, there is a problem that the guide rail is deformed by a load received from the vehicle due to long-term use.

  This invention is made in view of such a problem, Comprising: When a convex guide rail is employ | adopted as a guide rail laid in the lower part of the door apparatus with which the entrance / exit part of a mechanical parking apparatus is equipped. It is an object of the present invention to provide a door device for a mechanical parking device that does not generate noise or vibration when passing through a vehicle and that does not cause deformation of a guide rail.

In order to solve this problem, the configuration of the present invention is a door device that is provided at an entrance / exit of a mechanical parking device and that opens and closes from the center to the left and right. And a guide rail having a protrusion that is laid on the floor and engages with the groove of the door, the guide rails on both outer sides of the range through which the left and right tires of the vehicle pass, The guide rail is arranged so as to be divided into the inside of the range through which the left and right tires pass, and the end of the guide rail in the direction in which the tire passes has a tapered shape in which the upper surface is inclined downward toward the tip. Yes.

According to the configuration of the present invention, since the lower guide rail of the door is not arranged in the range through which the vehicle tire passes during entry / exit, noise due to the tire and the guide rail is not generated when the vehicle passes. No vibration is given to the vehicle. Further, the guide rail is not deformed by the load of the vehicle. In addition, the end of the guide rail in the direction in which the tire passes has a tapered shape with the upper surface inclined and descending toward the tip, preventing damage to the tire even if the tire contacts the guide rail. It becomes possible.

  Hereinafter, details of the present invention will be described with reference to the drawings. As an example of the mechanical parking device, FIG. 3 shows a plan view of an elevator parking device at the storage floor, and FIG. 4 shows a front view thereof. In the mechanical parking apparatus 10, a lift lift 12 is disposed in the center of a parking tower 11, and a pallet 13 on which a vehicle is mounted is placed on the lift lift 12. The lift 12 is suspended by wire ropes connected to four corners, and the wire rope is driven to move up and down the hoistway in the parking tower 11. Many stages of parking shelves are arranged on both sides of the hoistway, and after the vehicle gets on the pallet 13 on the lifting lift 12 on the entrance / exit floor, the lifting lift 12 moves up to a predetermined shelf, The pallet 13 and the vehicle are moved and stored in each shelf. In addition, the reverse operation is performed at the time of delivery, and the pallet 13 and the vehicle are transferred from the predetermined shelf to the entry / exit floor.

  The parking tower 11 is provided with an opening 15 for a vehicle to enter the mechanical parking device 10, and the opening 15 is provided with double-open doors 14 and 14. Here, FIGS. 3 and 4 show a state in which the opening 15 is closed by the doors 14 and 14.

  Next, FIGS. 1 and 2 show a state in which the doors 14 and 14 are opened and the opening 15 is opened. In FIG. 2, the right door 14 is omitted for easy understanding of the structure. The door 14 has a roller 30 at the upper part, and is suspended from an upper guide rail 31 fixed to the upper part of the opening 15 via the roller 30 and moved to the left and right by a mechanical mechanism. . On the other hand, a convex lower guide rail 16 is laid on the floor 17 at the lower part of the door 14 to guide the lower part of the door 14.

  FIG. 5 is a partial cross-sectional side view showing the relationship between the door 14 and the lower guide rail 16. A portion of the lower guide rail 16 excluding the upper protrusion 18 is buried and fixed below the floor surface 17a. On the other hand, a groove 19 is formed in the lower portion of the door 14 along the moving direction. A U-shaped guide shoe 20 is fitted into the groove 19, and the groove portion of the guide shoe 20 and the lower guide rail 16 are fitted. The protrusions 18 are engaged with a slight gap. Here, the material of the guide shoe 20 is preferably a synthetic resin, nylon, or the like having a low friction coefficient. In this way, the door 14 is guided by the lower guide rail 16 and can move smoothly without swinging in the left-right direction in the figure.

  As shown in FIGS. 1 and 2, the lower guide rail 16 is divided and laid in three places avoiding the position where the vehicle tire travels. Detailed arrangement and shape are shown in FIGS.

  First, the shape of the pallet 13 on which the vehicle rides is viewed from the front, and the outer start-up portion 21 bent upward so as to restrict the entry of the tire on the outer side in the width direction of the vehicle and the ride on which the vehicle tire rides It consists of a portion 22 and a central raised portion 23 that restricts entry into the pallet 13 when a small vehicle gets in. The vehicle moves so that the tire fits in the range of the boarding portion 22 when entering and leaving.

  In relation to such a shape of the pallet 13, the lower guide rail 16 a located at the center has the same length in the same range as the central raised portion 23 of the pallet 13, and the upper surface is inclined at both ends. The taper shape is lowered and the surface is chamfered so as to become narrower toward the tip portion even in plan view. Next, the lower guide rails 16b located on both outer sides are arranged outward from the position of the outer rising portion 21 of the pallet 13, and the end facing the tire running side is directed toward the tip in the same manner as described above. The upper surface is inclined and descends.

  In such a configuration, when the door 14 moves from the open state to the closed state, the door 14 is guided to the outer lower guide rail 16b and starts to move. Thereafter, a part of the door 14 is moved to the lower guide rail. Although it passes through a portion where the rail 16 is not disposed, as described above, the door 14 and the lower guide rail 16 are engaged with each other in an uneven shape, so that the door 14 can be satisfactorily formed only by the outer lower guide rail 16b. Can be induced. The doors 14 and 14 closed from both sides are guided again by the central lower guide rail 16a in the vicinity of the center, so that the doors 14 and 14 can be closed together and closed. Even if an external force is applied in this state, it will not move.

  As described above, according to the configuration of the present invention, since the lower guide rail 16 of the door 14 is not disposed in the range in which the vehicle tire passes, noise due to the tire and the lower guide rail 16 is generated when the vehicle passes. No vibration is given to the vehicle. Further, the end of the lower guide rail 16 in the direction in which the tire passes has a tapered shape in which the upper surface is inclined and descends toward the tip, so that the tire accidentally contacts the lower guide rail 16 Even if the tire is not damaged.
