JPH05280214A - Drop preventive device for car loading cage of three dimensional parking garage system - Google Patents

Abstract

PURPOSE:To prevent drop of a car loading part due to eventual occurrence of chain severance, etc., by surrounding the inside and outside surfaces of endless chains with guide rails which are overhung from respective vertical frames to the open area. CONSTITUTION:Endless chains 2a, 2b installed vertically on a front face vertical frame 1a and rear face vertical frame 1b are composed of a number of rolls 5a and inner side plates and outer side plates 5c having smaller width than the rolls 5a and coupled alternately. Inner side plates 5b at a certain spacing therefrom are extended outward to form an arm 6, and at the tip of each 6 a car loading cage 8 is hung through a hang shaft 7. The inside and outside surfaces of these chains 2a, 2b are surrounded over the whole extent with guide rails 9a, 9b so as to form a three-dimensional parking place. Thereby the chain remains in place even though it severs suddenly and is precluded from dropping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for a car basket in a multistory parking lot, and more particularly to a device for preventing an endless rotary chain for rotating and moving the car basket from accidentally cutting or loosening. It is a thing.

[0002]

2. Description of the Related Art Conventionally, in a multi-storey parking lot of this type, as shown in FIGS. 5 to 6, endless rotating chains 12 are vertically installed along the inside of front and rear or left and right vertical frames 11, respectively. An arm 13 composed of two inner and outer members is projected from the spaced apart portion so as to straddle the chain 12, and a suspension shaft 14 is provided between the arms 13 and 13 to rotate the car cage 15 up and down. It has been hung on.

[0003]

When the arm is composed of two inner and outer arms as described above, the outer peripheral surface of the endless rotating chain 12 and the vertical frame.
Since the 11 side is blocked by the outer plate of the arm 13, it is inevitable that the endless rotating chain 12 cannot be guided and exposed, and therefore the endless rotating chain is cut due to weight pressure or metal fatigue. If it is slackened or loosened, there is a problem in that it may be dangerous because it may fall from the cut or slackened portion together with the in-vehicle basket, and that the members of the automobile or parking lot may be damaged.

[0004]

According to the present invention, front and rear or left and right vertical frames and endless rotary chains are vertically installed along the inside of each of the vertical frames, and an arm is provided from a portion of the chains spaced from each other. In a multi-story parking lot that protrudes and hangs up and down so as to rotate and move the on-vehicle cage by a suspension shaft extending between the arms,
An arm protruding outward is formed by extending an inner plate spaced from the chain or a member attached to the inner plate to open the inner and outer peripheral surfaces of the chain and the vertical frame side from the vertical frame. An object of the present invention is to solve the problem by providing a guide rail extending over the open portion and surrounding the inner and outer peripheral surfaces of the endless rotary chain with the guide rail.

[0005]

According to the present invention, an arm projecting outward is formed by extending an inner plate having an interval of an endless rotary chain to be vertically installed along the inner side of a vertical frame or attaching a member to the arm. Regardless of whether it is projected, the chain is opened on its inner and outer peripheral surfaces and the vertical frame side, so a guide rail can be provided in an endless track shape with a stop point on the vertical frame, and the guide rail can rotate endlessly. It will be possible to surround the inside and outside of the chain.

In this way, when the inner and outer peripheral surfaces of the endless turning chain are surrounded by the guide rails, even if the endless turning chain is cut at the middle of the vertical portion due to weight pressure, for example, the chain has no place to go. It will stay on the spot and the fall of the car basket will not occur.

Embodiments Embodiments will be described below with reference to the drawings.

[0008] Endless rotating chains 2a, 2b so as to form endless tracks on the front vertical frame 1a and the rear vertical frame 1b, respectively.
Vertically installed. As shown in FIG. 4A, the endless rotary chains 2a and 2b are formed by alternately connecting a large number of rolls 5a and an inner plate 5b and an outer plate 5c having a smaller width than the rolls 5a. Reference numeral 3 denotes a drive wheel for rotating the endless rotating chain 2a, which meshes with the endless rotating chain 2a at the lower corner as shown in FIG. The other endless rotary chain 2b is adapted to mesh with a transmission wheel (not shown) rotated by the transmission shaft 4 so as to rotate synchronously. The endless rotary chains 2a, 2b form an arm 6 which extends an inner plate 5b with a constant space outward and extends outward at the extended portion. As shown in FIG. 4 (b), each arm 6 is formed in the shape of a hollowed triangular plate, and a suspension shaft 7 is provided between the ends of the arms 6 to suspend the car cage 8 from the suspension shaft 7. Endless rotating chains 2a, 2b mesh with inner and outer peripheral surfaces Except for drive and transmission wheels, the entire circumference is surrounded by fall prevention guide rails 9a, 9b with a U-shaped cross section to form a multi-level parking lot. Of. 10 is a guide rail 9a, 9b fixed to the vertical frame 1a, 1b.
It is a support frame of. Reference numeral 10a is a member for binding the guide rails 9a and 9b. Then, car C is a car cage 8 located on the ground.
The upper cage is carried upward by the rotation of the endless rotary chains 2a and 2b, and is parked in a three-dimensional manner.

[0009]

As described above, in the endless rotary chain,
Since the guide rail surrounds almost the entire circumference, even if the endless rotating chain suddenly cuts or loosens, the endless rotating chain has no place to go, so it does not fall or drop from the cut or slack end. As a result, it is possible to reliably prevent a personal injury, damage to a car, or a parking lot.

Since the arm supporting the suspension shaft is formed so as to project from the inside of the endless rotary chain and the outer peripheral surface of the chain and the vertical frame side are opened, the guide rail can be easily stretched from the open side. Produces the effect.
