It is composed of an endless chain 20 and an elevating frame 7 and a counterweight 21 which are attached to the chain and elevate or descend. When the elevating drive device 19 is operated, the elevating frame 7 descends from the two-dot chain line position to the solid line position. When it is done, the counterweight 21 which was previously in the lower position is in the solid line position, and when the lifting frame is raised to the two-dot chain line position, the counterweight is in the lower position.

Next, longitudinal feed of the tray 1, the tray longitudinal feeding device 2 _1, 2 ₂ of alternative such as shown in FIGS. 1 and 2, substantially the same structure as the previous similar tray pull or pull-out device 13 The tray vertical feeders 22 ₁ and 22 ₂ are installed on both sides of the front tray row to which the forklift 4 is not attached. Since the structure is completely the same, only _one tray vertical feeding device 22 ₁ will be described.

Tray longitudinal feeding apparatus 22 _1, as shown in FIG. 5 to FIG. 8, mainly, the bevel gear pair 24 (FIG. 7) of the directly connected to the geared motor 23 and the motor main driver sprocket
25 and the driven sprocket 26, the upper and lower drive sprockets 27 coaxially attached to the driven sprocket, and the upper and lower driven sprockets 29 around which the two endless chains 28 driven by the driven sprockets are hung.
In this case, as shown in FIGS. 6 and 7, the bevel gear pair and the main driving sprocket are mounted on a drive shaft 32 which is pivotally installed inside a frame 30 via a pair of bearings 31, The driven sprocket and the drive sprocket are mounted on another drive shaft 34 pivotally mounted on the outside of the frame via a pair of bearings 33, and these sprockets are mounted between the main drive sprocket and the driven sprocket. It is driven by the chain 35 that is installed.

Also, as shown in FIG. 8, upper and lower driven sprockets
29 is mounted on a drive shaft 38 which is pivotally mounted on the outside of a pedestal 36 through a pair of bearings 37.
Two hook-shaped connecting arms 39, 40 at or near a half position of the total length of the two endless chains 28 that are mounted on the driven sprocket 29 and driven sprocket 29 and circulate in the horizontal plane for driving circulation.
, And the movable pins 41, 42 which are erected on the arms so as to be overhanged are provided with groove-like hooking metal fittings 15 '(fifth portion) provided at the front left corner of the back surface of the tray 1. (Figure)
The pulling rollers 43 and 44 which are fitted to are attached. Furthermore, chain guides 45 are provided on both sides of the mounts 30 and 36,
In order to prevent the slack of the two endless chains 28 and to perform a smooth circulation drive, a plurality of guide rollers (not shown) and two connecting arms are arranged on the chain at equal pitches.
Guide rollers 46 and 47 are attached to 39 and 40, respectively.

(Operation) In FIGS. 3 and 4, the left tray vertical feeding device 22 ₁
Is installed in the space 48 on the front side of the forklift 4 and on the lower surface of the left end tray 1 of the front tray row in the range of the total tray length plus the distance between tray rows.
22 ₂ is intended to be installed at the same range before the lower surface of the right end tray 1 forward tray column, the tray longitudinal feeding apparatus 22 ₁ the tray to be vertically and horizontally moved in the opposite direction synchronously simultaneously,
22 ₂ and tray traverse devices 3 ₁ and 3 ₂ are operated to move and circulate in a two-step system for loading and unloading of automobiles. In this case, each tray connected by a coupler 49 is mutually connected. When 1 is traversed, the traverse wheels 5 travel on the traverse fixed rails 50 (the longitudinal wheels 6 are free), and when longitudinally fed, the longitudinal wheels 6 travel on the longitudinal feed fixed rails 51. The vehicle runs (the traverse wheels 5 are free).

Therefore, according to the present invention, in the conventional multi-layer plane circulating parking equipment shown in FIG. 1 and FIG. 2, the tray vertical feed devices 2 ₁ , 2 ₂ are removed and the forklift 4 is attached. since the tray longitudinal feeding apparatus 22 _1, 22 ₂ are respectively installed on the tray full length on each side of the tray column which is not within the range obtained by adding the tray column distance, the tray 1 of the increase in the dead space S ₁
In addition, when the forklift 4 passes through the end of the adjacent tray row of the parking device unit U of the first underground layer, according to the conventional parking equipment, as shown in FIG. 9 (b). As shown, since the moving pin 42 'attached to the connecting arm 40' of the drive endless chain 28 'is unoverhung, the driven sprocket
Since the end surface of the traverse tray 1 mounted on the forklift interferes with the tooth tips of 29 'in a plane,
While the lift cannot pass through in any state, according to the parking equipment of the present invention, as shown in FIG. 9 (a), the moving pin attached to the connecting arm 40 of the drive endless chain 28 is used. Since 42 is an overhang, when the lifting frame 7 of the forklift 4 passes through the tray row end, the moving pin escapes to the position indicated by the solid line, and when the forklift stops at the circulation level,
After the movable pin turns to the position of the broken line and stops, the movable circulation of the tray 1 in the vertical direction and the horizontal direction becomes possible.

Since the driven sprocket 29 'is set back to the position of the driven sprocket 29 by the length l, a flat surface is provided between the tooth tip of the sprocket and the tray 1 on the elevating frame 7 of the forklift 4. Since the clearance c is formed in the above, the lift can be passed through, and the cores of the moving pins 42 and 42 'in this case are unchanged.

(Effects of the Invention) From the above, according to the present invention, the vertical rail for vertical tray feeding and the horizontal rail for horizontal tray feeding are laid on the elevating frame of the forklift, and the tray row without the forklift is attached. Since there is a tray vertical feed device that vertically feeds trays with endless chains with overhanging moving pins on both sides, the number of parking spaces should be increased to one for each layer and two for two layers. At the same time, a gap is formed between the tray on the lifting frame of the forklift and the addendum of the driven sprocket, so that the lifting frame can move up and down without interfering with each other when the tray row end passes. If possible, tray longitudinal and lateral movement circulation can be performed.
