Description

[Detailed description of the invention] (Field of industrial application) This invention stores vehicles by moving a large number of vehicle mounting cages in a circular motion in the vertical direction, and also lifts the chassis from the front and rear cage frames of the cages. Regarding vertical circulation parking equipment, which allows the vehicle platform to rotate so that vehicles can always be taken out of the vehicle in forward motion,
In particular, the present invention relates to an improvement in the mechanism for attaching and detaching the cage to the chassis.

(Prior Art) Conventionally, as the above-mentioned vertical circulation type parking equipment, there has been one disclosed, for example, in Japanese Patent Application Laid-open No. 75172/1983. This parking equipment is designed to raise the front and rear cage frames after lifting the chassis so that the chassis and the mounted vehicle do not come into contact with the front and rear cage frames when the chassis turns, even if the overall length of the chassis and the height of the chassis are minimized. After rotating and retreating in directions that separate them from each other back and forth, the chassis is turned. To explain in more detail with reference to FIG. 8, the cage 1 has a suspension shaft 2 extending horizontally in the front-rear direction, and upper horizontal portions of the cage 1 are attached to brackets 3a and 3b provided at the front and rear of the suspension shaft 2, respectively. The front and rear cage frames 4a and 4b are pivotally attached to the front and rear cage frames 4a and 4b, and the front and rear sides of the left and right sides are pulled out upward from the bottom of the left and right legs of the front and rear cage frames 4a and 4b, respectively. and a chassis 5 mounted in possible engagement. Therefore, when the vehicle W leaves the garage, the lifter 7 having the turntable 6 on the upper part
As a result, the chassis 5 and the mounted vehicle W are lifted with the chassis 5 placed on the turntable 6, and at the same time, the engagement members 8a of the cage frame opening/closing device 8 installed on the lifter 7 are moved forward and backward. cage frame 4
It engages with the lower parts of a and 4b. Next, the front and rear cage frames 4a and 4b are rotated and retracted in a direction in which they are separated from each other in the front and rear directions by the longitudinal extension of the engagement member 8a. In this state (the state indicated by the dashed line in FIG. 8), the turntable 6 turns 180 degrees to change the direction of the chassis 5 and the vehicle W. After that, the front and rear cage frames 4 are again
a and 4b return to their original positions, and finally, as the lifter 7 descends, the chassis 5 is engaged with and placed on the lower portions of the front and rear cage frames 4a and 4b. This completes a series of direction changes of the vehicle W, and the vehicle W can exit the cage 1 by driving forward.

(Problem to be solved by the invention) In the above-mentioned parking equipment, the front and rear cage frames 4
In order to successfully carry out the lifting and turning of the chassis 5 with the rocking of the cages a and 4b, it is essential to ensure that the overall shape of the cage 1 is not deformed. for example,
Front/rear cage frame 4a, 4b upper part and bracket 3
If the support means a, a' between a and 3b and the support means b and b' between the lower left and right legs of the front and rear cage frames 4a and 4b and the chassis 5 are all pin-jointed, the mounted vehicle W
Due to the unevenness of the front and rear loads Wx ₁ and Wx ₂ , or the horizontal force Wy generated when the cage 1 circulates, the cage 1 is caused to move in the horizontal direction of the chassis 5 as shown by the two-dot chain line in Fig. 8. As a result, the overall shape deforms. In other words, this deformation of the overall shape of the cage 1 means that the center of the undercarriage 5 is displaced from the center of rotation in the front-rear direction, and the undercarriage 5 is lifted and turned eccentrically. If this deformation is large, the undercarriage 5 When returning to the lower position after the lifting and turning, the engagement between the chassis 5 and the front and rear cage frames 4a, 4b by the support means b, b' becomes substantially impossible.

The present invention has been developed in consideration of these points, and even if horizontal force is applied due to uneven loads on the front and rear of the chassis due to mounted vehicles or horizontal force due to circulation movement of the cage in vertical circulation parking equipment, the entire cage remains in normal condition. It is an object of the present invention to provide a mechanism for attaching and detaching a cage to a vehicle chassis, which maintains the same shape and eliminates the above-mentioned drawbacks associated with conventional shape deformation.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention is such that a plurality of vehicle mounting cages are suspended in a chain from an endless chain that circulates in the vertical direction. A vertical circulation parking facility in which the cage is composed of front and rear gate-shaped cage frames and a vehicle platform that is removably engaged with and placed on the lower left and right legs of the front and rear cage frames, and the above-mentioned 4 installed at the front and rear of both the left and right sides of the chassis.
a set of first engaging means, and four sets of four sets that are provided at the lower portions of the left and right legs of the front and rear cage frames in correspondence with the respective first engaging means and engage with the corresponding first engaging means. and second engagement means. Each of the first engaging means includes an inner latch and an outer latch that are spaced apart from each other in the front and rear direction on the front and rear sides of the left and right sides of the vehicle chassis. Become. Each of the second engaging means is formed by bending each of the lower portions of the left and right legs of the front and rear cage frames approximately horizontally in opposite directions in the front and back, and is arranged in a manner that corresponds to the inner side and outer side latches. It consists of a horizontal bent leg extending in the direction, and a pin protruding in the left-right direction at a position corresponding to the outer latch on the horizontal bent leg. The lower surface of each of the inner latches is formed with a cutout hole that extends continuously in the front-rear direction and has a substantially semicircular cross section into which the horizontal bent leg can fit, and the lower surface of each of the outer latches has a cutout hole that extends continuously in the front-rear direction and has a substantially semicircular cross section into which the horizontal bent leg can fit. A slot is formed that extends continuously in the left-right direction and into which the pin can be fitted. The first engagement means and the second engagement means are such that the distal end of the horizontally bent leg is fitted into the notch hole, and the pin is fitted into the slot so that the front and rear cage frames are engaged with each other. They are rigidly connected to each other so that the chassis can be removed upward.

(Function) As a result, in the present invention, in the engagement between the front and rear portions of both left and right side surfaces of the vehicle chassis and the left and right rear lower portions of the front and rear cage frames, the notch hole of the inner latch in the first engagement means on the chassis side; The tips of the horizontally bent legs of the second engagement means on the cage frame side and the pins protruding from the horizontally bent legs are fitted into the slots of the outer side latch, respectively, at two locations spaced apart from each other in the front and back. Due to the fitting portions in the front and rear directions and the left and right directions, both engaging means are rigidly connected to each other so that the chassis can be pulled out upward relative to the front and rear cage frames and cannot be moved back and forth or left and right. Even if the front and rear cage frames and the chassis tend to be elastically deformed due to an uneven load being applied to the rear part of the vehicle mounted on the vehicle or a horizontal force applied to the entire cage in the longitudinal direction, the first and second engagements The rigid connection between the means prevents this deformation and ensures the initial unloaded shape of the cage.
