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, and a lift rod sliding in these guide rails. And a guide engaging member having a guide roller attached to the lifting rod and sliding the lifting rod along the guide rail, and a lifting claw integrally attached to the lifting rod and supporting the tray. The hoistway is lifted or lowered by being placed on the engaging member via a tray. 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 able to traverse via rails via wheels, and a car is taken in and out by passing a tray between the tray traversing device and the elevator device. ing.

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 a groove-like elevating claw insertion portion is formed on one surface thereof along the longitudinal direction. The raising / lowering claw has its base end integrally attached to the lifting / lowering rod, is slidably assembled in a guide rail via a guide roller, and moves up and down along the lifting / lowering claw insertion portion.

[0004] With such a construction of the elevator apparatus, the traversing rail is provided with an intermittent portion for the lifting claw to pass across the traversing rail when the tray engaging member moves up and down in the hoistway. Also, in order to make the trolley run on the traversing rail with four wheels in total, two wheels on one side, an intermittent portion is formed diagonally toward the four corners of the hoistway. It is designed to pass diagonally.

[0005]

In a conventional tray-type elevator type multi-story parking device of this type, a vehicle transport device is used to transport a tray between an entrance / exit garage and a rear garage. Although the tray is installed, the width of the tray is larger than the width of the vehicle transport device, and when transporting the tray, there is a possibility that the side edge portion of the tray hits the guide rail. Also, in the conventional tray-type elevator type simultaneous multi-story parking device, as shown in FIG. 5, originally, the intermittent portion 42a is formed in the traversing rail 41 at right angles to the longitudinal direction of the traversing rail 41, and By crossing the rail 43 at right angles to the longitudinal direction of the traversing rail 41, the distal end portion 44 and the proximal end portion 45 are intermittently connected to the intermittent portion 42a.

3 is preferred in terms of strength. However, in such an intermittent portion 42a of the traversing rail 41, in order to prevent the wheels of the traversing truck from falling into the intermittent portion 42a, it is necessary to use a total of eight wheels, four wheels on one side, for the traversing truck.
For this reason, there is a problem that the number of parts increases. On the other hand, as shown in FIG.
By forming the 2b obliquely, the traversing rail 41 is substantially in a continuous state, so that a traversing carriage having a total of four wheels on one side can be used. However, in this case, the lifting claw 4
Guide rails 4 to pass through the oblique intermittent portion 42b.
When the guide rail 46 is installed, it is necessary to face the surface having the elevating and lowering claw insertion portions 47 obliquely so as to face the inclined direction of the intermittent portion 42b. The occupied width L for the installation of the guide rail outside the rail 41 is larger than the width of the guide rail 46 itself. As a result, the entire device becomes large, and the width of the traversing rail 41 cannot be increased. Was.

SUMMARY OF THE INVENTION The present invention solves such a conventional problem. The tray can be transported without colliding with a guide rail located inside where the tray is transported. It is an object of the present invention to provide a simultaneous multi-story parking device capable of reducing the entire width of the device while maintaining a high strength while keeping the occupied width for guide rail installation small.

[0007]

Next, reference numeral 29 denotes the end of the transport path of the vehicle transport device 35 in the hoistways 13 and 14, that is, the vicinity of the portion (boundary portion) where the entrance / exit garage 11 and the rear garage 12 are connected. A second tray engaging member that is disposed at a position (hereinafter referred to as a garage boundary portion) and moves up and down the vehicle. In the present embodiment, the second tray engaging members 29 are paired with the hoistways 13 and 14 at two corners on both sides of the garage boundary portion with the hoistways 13 and 14 interposed therebetween. It is erected.
The configuration of the second tray engaging member 29 is as follows.
Except for the structure of the lifting claw 30, the first tray engaging member 1
9, the same parts as the guide rail 20, the guide roller 21, the elevating rod 23, and the like are denoted by the same reference numerals, and description thereof is omitted.

In the second tray engaging member 29,
As shown in FIG. 3, each of the lifting claws 30 is formed by bending so that a portion between a distal end portion 30 a supporting the automobile and a base end portion 30 b on the guide rail 20 side is deflected. That is, the lifting claw 30 has an inclined portion 30c along the oblique intermittent portion 27a between the distal end portion 30a and the proximal end portion 30b so as to pass through the intermittent portion 27a of the traversing rail 27. It is bent at portions corresponding to both ends of 27 a and extends in a direction perpendicular to the traversing rail 27. The distal end portion 30a and the proximal end portion 30b of the lifting claw 30 are displaced in the longitudinal direction of the traversing rail 27, and the tray supporting portion 30d of the distal end portion 30a is extended in the longitudinal direction of the traversing rail 27. At the same time, it projects along the sides of the hoistways 13 and 14 at right angles to the base ends 3 thereof.
Ob is slidably incorporated in the guide rail 20 via the guide roller 21. As a result, each guide rail 20 is installed at right angles to the longitudinal direction of the traversing rail 27 with the surface having the elevating claw insertion portion 20a facing the intermittent portion 27a in advance.

The distal end 30a and the proximal end 30b of the lifting claw 30
Between the pair of second tray engaging members 2

In this embodiment, the tray 24 is
For the first tray engaging member 19, one unit (the lifting claw 22
Is one), and the second tray engaging member 29 is supported at three points using two units (two lifting claws 30). Since the members in FIG. 4 are the same as those in the above-described first embodiment, the same reference numerals are given and the duplicated description is omitted. That is, the guide rails 20 are installed in pairs at both corners of the hoistways 13 and 14 at the garage boundary portion, while the widths of the hoistways 13 and 14 are provided at the end of the transfer path of the vehicle transfer device 35. Each of them is installed at a central position in the direction at right angles to the longitudinal direction of the traversing rail 27. Of the three guide rails 20, the guide rails 20 installed in pairs are slidable via guide rollers 21 as shown in FIG. Ascending and descending along the elevating claw insertion portion 13a, the ascending and descending claw 22 having a "U-shaped" structure is provided on the remaining guide rail 20 (one) as shown in FIG. It is slidably assembled via a roller 21 and moves up and down along the elevating claw insertion portion 13a.

On the other hand, a pair of traversing rails 27 are arranged between the hoistways 13 and 14 and the parking sections 25 of each level.
On this pair of traversing rails 27, a traversing carriage 20 is arranged so as to be traversable by a total of four wheels, two wheels on one side. On one traversing rail 27 on the side where the two guide rails 20 are erected, a position corresponding to each guide rail 20 is provided.
When the tray engaging member 29 moves up and down in the hoistways 13 and 14, the intermittent portions 27 a for each of the lifting claws 30 to pass across the traversing rail 27 are formed obliquely with respect to the longitudinal direction of the traversing rail 27. And each lifting claw 3
0 is obliquely passed along the slope to the intermittent part 27a by the slope part 30c. On the other hand, 1
On the other traversing rail 27 on the side where the guide rail 20 is erected, a lifting claw is provided at a position corresponding to the guide rail 20 when the tray engaging member 19 is raised and lowered in the lifting paths 13 and 14. An intermittent portion 27a is formed obliquely for passing the traverse rail 22 across the traversing rail 27, and the elevating claw 22 is provided between the first bent portion 22c and the second bent portion 22d in the intermittent portion 27a. On the other hand, it passes obliquely along the slope.

As described above, the features of the lifting claws 22, 30 of the first tray engaging member 19 and the second tray engaging member 29, respectively, allow the lifting claws 22 to have high strength, When the car is supported by the pawls 22, it is possible to prevent a load from being applied to one of the two guide rollers 21, thereby reducing wear on the guide rollers 21 and reducing the thickness of the guide rails 20. In addition, the installation occupied width L of the guide rail 20 is the width of the guide rail 20 itself, which can be minimized.
By realizing the three-point support structure of the tray 24, the number of components such as the guide rail 20, the lifting claw 22, and the like can be reduced, and the cost can be further reduced.
Further, since the fulcrum supporting the tray is located closer to the lifting rod 23, the moment applied to the lifting rod 23 can be reduced, and the size of the guide rail 20 and the lifting rod 23 can be reduced. Further, the second embodiment has an advantage that a relatively lightweight vehicle can be loaded with a simple structure.
