BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cage guiding device for a mechanical parking device.

[0002]

2. Description of the Related Art A typical example of a conventional mechanical parking device is a vertical circulation parking device. In this parking device, as shown in FIG. 2, a main chain 3 is endlessly wound around sprockets 1 and 2 provided vertically, and a car storage cage 4 is attached to the main chain 3 via an attachment 3a. Are connected at equal intervals, and each cage 4 is circulated by a side roller 4a (provided on the cage 4) guided by a guide rail (not shown). The cage 4 is usually provided with a door protector (not shown) to prevent a half-door accident.

Depending on where the entrance of the car 5 is provided, such parking devices include a bottom entry type, a top entry type, an intermediate entry type, and the like. The device will be employed, but in the case of the intermediate entry type, the structure is slightly different from that of the very common bottom entry type.

[0004] That is, as shown in FIG. 2, when the hanging position of the cage 4 by the attachment 3 a is at the center as in the bottom entry type, the main chain 3 hinders the entrance and exit of the automobile 5, so that the hanging position is The position is shifted to either the left or the right, and the mounting position of the side roller 4a for guiding the cage 4 and the guide rail is provided near the front and rear sides of the cage in accordance with the shift of the hanging position.

Here, FIG. 3 is a plan view of an intermediate entry type cage at an intermediate entrance, and FIG. 4 is a side view of the intermediate entry type cage. In the figure, reference numeral 11 denotes a pipe formed in a loop shape. Of the cage 10 which is provided before and after. 12 is a floor of the cage 10, 13 is a parallelogram shaped door protector rotatably provided on the side of the floor 12 (the driver's seat side of the car 5 to be stored), and 13 'is the side of the floor 12 (the car 5).
A door protector 14 fixed to the passenger seat side of the vehicle) is a rod for operating the door protector 13.
The door protector 13 is lowered, and the door of the automobile 5 can be opened and closed.

Reference numeral 16 denotes a cover for protecting a spring (not shown) for constantly urging the rod 14 in the direction of the arrow to maintain the door protector 13 in an upright state, and 17 pivots on the side of the floor 12 below the cover 16. Freely provided side rollers, 17 'are side rollers rotatably provided on the opposite side of the floor 12, and 20 and 20' are guide rails erected on the building side. 1
The guide 7 'prevents the cage 10 from swinging.

[0007]

However, when the side roller 17 is provided below the cover 16, a problem as shown in FIG. 5 occurs. That is, cage 1
When 0 circulates in the direction of the arrow through the lowermost portion, since the side roller 17 is located below the cover 16, the guide rail 20 has the cover 1 before the side roller 17.
6 comes in contact with each other and noise is generated.
0 will vibrate. Such a problem is caused by each cage 1
0 occurs every time such a position is passed, and improvement has been strongly desired. The present invention has been made in view of the above points, and an object of the present invention is to provide a cage guide device that is less likely to generate noise.

[0008]

According to the present invention, a plurality of car storage cages are connected, and the cage is provided with rollers.
A guide rail is provided on the building side, the rollers are guided by the guide rails, and the cage is circulated in the vertical direction, and a part of the guide rail near the bottom is provided with a roller guide device, The upper member of the rollers of the cage is guided by the roller guide device.

[0009]

With the above arrangement, the cage is smoothly circulated.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is an enlarged view of a cage guide device 30 showing one embodiment of the present invention, FIG. 6 is a left side view of FIG. 1, and FIG. 7 is an enlarged plan view showing an arrangement relationship between a side roller 17 of the cage 10 and the cage guide device 30. In the drawings, the same reference numerals as those in FIGS. 2 to 5 indicate the same components.

Reference numeral 30 denotes a cage guide device according to the present invention. A notch is provided in the conventional guide rail 20 in an area where the cage 10 may circulate and the cover 16 may come into contact, and a roller guide device 31 described later is provided. It is configured to be fitted. The roller guide device 31 has a base having a cross-sectional shape having concave portions 31a and 31b on the left and right sides and a convex portion 31c at the center. A main roller 32 is rotatable in the concave portion 31a, and a slave roller 33 is rotatable in the concave portion 31b. Attached in a row, the projection 31
The structure guides the side rollers 17 of the cage 10 by c.

Then, the cover 16 is moved by the main roller 32.
Mainly, but since the cover 16 is a member having a long depth, the slave roller 33 has a role of assisting the main roller 32,
A roller having a smaller diameter than the main roller 32 is attached (of course, a roller having the same diameter may be used).

Therefore, even if the side roller 17 is provided below the cover 16 as in the prior art, the cover 16 approaches the cage guide device 30 as shown in FIG. In this case, since the guides are guided by sequentially contacting the plurality of main rollers 32 of the roller guide device 31, there is very little risk of generating noise, and the floor 12 of the cage 10 is smoothly circulated.

In the above description, the case where the member for the door protector exists above the roller 17 provided on the floor 12 of the cage 10 has been described. Similarly, it is possible to adopt the present invention. Further, the structure of the roller guide device is described as a structure including a double roller row, but this is not limited to the embodiment.

[0015]

As described above, according to the present invention, even if an obstacle is disposed above the side rollers of the cage, the roller guide device mounted on the guide rail can extremely smoothly. Because of the guidance, harsh noise can be effectively and minimized.
