Description

[Detailed description of the invention] (Field of industrial application) The present invention is designed to move a large number of vehicle mounting cages in a circular manner in a vertical direction to store the vehicle, and to move the vehicle mounting cages from the front and rear cage frames of the cages to the vehicle chassis. The present invention relates to a vertical circulation parking facility in which the vehicle chassis is lifted and the chassis is rotated so that vehicles can always be taken out of the chassis in forward motion, and in particular, it 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. 61-75172. 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 retracting outward in the longitudinal direction away from each other, the chassis is turned. This conventional parking equipment will be described in more detail with reference to FIG. Brackets 3a, 3 fixed to the rear
Front and rear cage frames 4a and 4b pivotally attached to the front and rear cage frames 4a and 4b so as to be swingable in the front and rear directions, and the front and rear cage frames 4a and 4b.
It consists of a chassis 5, with the front and rear portions of the left and right sides removably engaged with the lower portions of the left and right legs, respectively. Therefore, when the vehicle W leaves the garage, the lifter 7 with the turntable 6 rises, and the vehicle chassis 5 and the vehicle W mounted thereon are lifted up with the chassis 5 placed on the turntable 6, and at the same time, the lifter 7 An engaging member 8a of a cage frame opening/closing device 8 installed at 7 engages with the lower portions of the front and rear cage frames 4a and 4b. Next, the front and rear cage frames 4a, 4b are rotated and retracted outward in the front-back direction away from each other due to the extension of the engagement member 8a in the front-back direction. 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. Then, the front and rear cage frames 4a and 4b return to their original positions, and finally, the lifter 7 descends and the vehicle platform 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 4a,
In order to successfully lift and turn the chassis 5 with the rotation of the cage 4b, it is essential to ensure the overall shape of the cage 1. For example, the support means a, a' between the upper parts of the front and rear cage frames 4a and 4b and the brackets 3a and 3b, and the lower parts of the left and right legs of the front and rear cage frames 4a and 4b and the chassis 5
If the support means b and b' between the cages are both pin-jointed, the cage may be damaged due to uneven front and rear loads Wx ₁ and Wx ₂ due to the mounted vehicle W or the horizontal force Wy generated when the cage 1 circulates. As shown by the two-dot chain line in FIG. 8, the overall shape of the vehicle 1 deforms as the chassis 5 moves in the horizontal direction. 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 longitudinal direction, and the undercarriage 5 is lifted eccentrically and turns.If this deformation is large,
When the chassis 5 returns to the lower position after being lifted and turned, the chassis 5 and the front and rear cage frames 4 are supported by the supporting means b and b'.
Engagement with a and 4b becomes virtually impossible.

The present invention has been developed in view of these points, and even if horizontal force is applied due to the uneven load on the front and rear of the chassis due to the mounted vehicle or the cyclical movement of the cage, the cage as a whole maintains its normal shape, making it possible to maintain the normal shape of the cage as a whole. The purpose of this invention is to eliminate the above-mentioned drawbacks associated with shape deformation.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention is such that a large number of vehicle mounting cages are suspended in a chain from an endless chain that circulates in the vertical direction. consists of a suspension shaft that extends horizontally in the front and back direction and whose front and rear parts are suspended and supported by the endless chain, and a front and rear cage frame that is swingably supported in the front and rear directions of the suspension shaft. The object of the present invention is a vertical circulation parking facility comprising a vehicle platform that is removably engaged with the lower left and right sides of the front and rear cage frames. and first engaging members provided at the front and rear portions of the left and right side surfaces of the vehicle chassis, and corresponding to the first engaging members provided at the left and right lower portions of the front and rear cage frames. and a second engaging member that is engageable with the first engaging member.
One of the first and second engaging members includes a bar extending in the vertical direction, and a pin provided on the bar and protruding on both sides of the bar in the left-right direction. 1st above
and the other of the second engaging members is provided to face the bar in the front-back direction, and the surface facing the bar is open so that the bar can be inserted, and the other side is inward in the front-back direction of the front and rear cage frames. A latch having a U-shaped cross section into which the bar fits when the bar is rotated, and a latch having a U-shaped cross section at the tips of both sides of the latch, corresponding to the pin, and extending from the tips of both sides in a direction facing the bar. an extension portion provided to extend out; and an extension portion formed on both extension portions that allows the vehicle chassis to be pulled out upwardly relative to the front and rear cage frames, and cooperates with the fitting of the bars and latches to - The rear cage frame is provided with a cutout hole that engages with the pin in a manner that it cannot rotate in the longitudinal direction with respect to the vehicle body.

(Function) As a result, in the present invention, the first and second engaging members fit each bar into the U-shaped groove of the latch, and fit the pin into the notch hole.
The vehicle chassis is removable upward relative to the front and rear cage frames, and the front and rear cage frames are engaged with the vehicle chassis so as to be unrotatable in the longitudinal direction to horizontally support the vehicle chassis. In this state, uneven loads are applied to the front and rear of the chassis, horizontal forces are applied to the entire cage, especially in the longitudinal direction, and the chassis tends to tilt with respect to the horizontal due to elastic deformation of the chassis and the front and rear cage frames. If so, the bar will come into contact with the bottom of the U-shaped groove of the latch. Therefore, the chassis is not substantially deformed by being affected by only a slight play in the fit between the pin and the cutout hole, and the cage as a whole maintains its normal shape when no load is applied.
