DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator type multi-story parking device.

[0002]

2. Description of the Related Art Conventionally, for example, in a tray-type elevator-type multi-story parking device, a total of four guide rails erected at four corners of a hoistway are slidable via guide rollers. And a lifting lift composed of four lifting claws that ascend and descend on the hoistway, constitute a tray lifting device, and place the vehicle on the lifting lift via the tray to raise or lower the hoistway. It has become. Also, a plurality of parking sections are formed hierarchically along both sides or one side of the hoistway, a pair of traversing rails disposed between the hoistway and the parking sections of each level, and a pair of traversing rows of each level. A tray traversing device is constituted by a traversing truck arranged so as to be traversable via wheels on a rail, and a car is taken in and out by passing a tray between the tray traversing device and the tray elevating device. Has become.

In this type of conventional multi-story parking device, the guide rail is formed of a hollow columnar member having a square cross section, and one surface thereof is formed with a vertically extending claw insertion portion along the longitudinal direction. The lifting claw has its base end slidably assembled in a guide rail via a guide roller so as to move up and down along the lifting claw insertion portion.

[0004] Due to such a configuration of the tray elevating device, the traversing rail is provided with an intermittent portion for allowing the elevating claw to pass across the traversing rail during the elevating operation of the hoistway of the elevating lift. An intermittent part is formed diagonally toward the four corners of the hoistway so that the traversing carriage can be driven by a total of four wheels on one side, and the hoisting pawl is inclined obliquely to the intermittent part with respect to the intermittent part. It is designed to pass through.

[0005]

By the way, in this type of conventional elevator-type multi-story parking device, intermittent portions 42a are originally provided on the traversing rail 41 as shown in FIG.
Is formed at right angles to the longitudinal direction of the traverse rail 41, and the elevating claw 43 is traversed at right angles to the longitudinal direction of the traversing rail 41, so that the distal end portion 44 and the proximal end portion 45 are disposed to face each other on both sides of the intermittent portion 42a. This is preferable in terms of the strength of the lifting claw 43 supporting the automobile. However, in such an intermittent portion 42a of the traversing rail 41, it is necessary to use a total of eight wheels, four wheels on one side, for the traversing truck, and thus there is a problem that the number of parts increases. On the other hand, as shown in FIG. 5, by forming the intermittent portion 42b of the traversing rail 41 diagonally, a traversing carriage of two wheels on one side, that is, four wheels in total, can be used. Intermittent part 42
In order to allow the guide rail 46 to pass through the guide rail 46, it is necessary to turn the surface having the elevating and lowering claw insertion portions 47 obliquely so as to face the inclining direction of the intermittent portion 42b. The occupied width L for setting the guide rail outside the traversing rail 41 at a large angle with respect to the guide rail 46 is larger than the width of the guide rail 46 itself. There was a problem that the width could not be expanded.

The present invention has been made to solve such a conventional problem. In this case, the lifting claw has high strength, while the occupation width for installing the guide rail can be reduced, and the entire apparatus can be reduced. An object of the present invention is to provide an elevator-type multi-story parking device capable of expanding the width of a traversing rail.

[0007]

According to the present invention, in order to achieve the above object, an intermittent portion of a traversing rail is provided between a leading end of each lifting claw supporting a vehicle and a base end on a guide rail side. Bends into an approximately `` C '' shape that can pass through, and arranges the distal end and the proximal end on both sides of the traversing rail, and attaches the distal end and the proximal end to the traversing rail on both sides of the traversing rail, respectively. It is directed at right angles to this.

[0008]

Therefore, according to the present invention, with the above configuration, the distal end portion and the base end portion of the lifting claw are arranged opposite to both sides of the traversing rail, so that the lifting lift can maintain high strength, In addition, since the base end of the lifting claw is oriented at right angles to the traversing rail, the guide rail can be installed at right angles to the traversing rail, and the occupied width for installing the guide rail can be reduced.

Since the lifting claw 150 is provided, the lifting claw 150 can be provided with high strength, and when one of the two guide rollers 14 is supported by the lifting claw 150, the load can be prevented from being biased to one of the two guide rollers 14.
