Description

[Detailed description of the invention] The present invention is designed to move the cage to store the loaded vehicle, and in addition to preventing the door opening accident of the loaded vehicle, it also prevents the cage from shaking at the vehicle entry position. The invention relates to a mobile parking facility for the purpose.

The present applicant has previously disclosed in Japanese Patent Application Laid-open No. 52-54772 and No. 53-14738N that the cage has a pivot point part that is installed on the side of the vehicle chassis and that fixes a driven member to the underside of the vehicle chassis, and is always equipped with an appropriate spring. It consists of a swingable door-opening prevention frame that maintains the upright state by force, and a frame drive mechanism that is installed on a fixed floor at the vehicle entry position and has a pushing member attached to the tip of the plunger of the operating cylinder. During cage circulation, the door opening prevention frame is raised to prevent the door from protruding outside the cage even if the door of a partially opened vehicle is opened, and when the cage is stopped at the vehicle entry position, the plunger is extended. Disclosed is a mobile parking facility in which the pushing member collides with the driven member to tilt the door opening prevention frame body against a spring force, thereby allowing the vehicle door to be completely opened and the driver to enter the vehicle. did.

However, the above-mentioned mobile parking equipment only serves to prevent accidents caused by half-opened vehicle doors, and cannot go so far as to prevent the cage from shaking when entering and exiting the vehicle at the entry position. Ta.

Therefore, conventionally, in order to prevent the cage from shaking, a rod was extended toward the underside of the chassis of the cage while it was stopped on the fixed floor of the vehicle entry position, separately from the vehicle door opening accident prevention device described above. Therefore, it was necessary to install a device to prevent the cage from shaking.

In view of the above-mentioned circumstances, the present invention focuses on the fact that both the tilting of the door-opening prevention frame and the prevention of cage shaking are requirements that are limited to cages that require vehicle entry and exit, and that the same means is used to perform both functions. In other words, the abutment portions of the driven member and the pushing member are formed so that they can engage with each other in a concave and convex manner, and during the tilting operation of the door opening prevention frame, this The same drive mechanism prevents the cage from shaking by maintaining the convex-concave fit, and in addition to the original function of the door-opening prevention frame to prevent vehicle door opening accidents, the same drive mechanism also prevents the cage from shaking at the vehicle entry position. The aim is to provide mobile parking facilities that can be used.

Hereinafter, a detailed description will be given based on the embodiments shown in the drawings.

For convenience of explanation, left and right in Figure 1 are referred to as 1 left yo, 1 right,

Reference numerals 9 and 10 designate a fixed shelf erected on the upper surface of the left side of the chassis 6a of the cage 6, and a door opening prevention frame swingably provided on the right side (driver's seat side of the mounted vehicle W).

The door opening prevention frame 10 has front and rear leg portions 10a and 10b bent horizontally toward the back surface of the vehicle chassis 6a so that it can stand up and tilt in a parallel link shape within one vertical plane on the right side of the vehicle chassis 6a,
The horizontal bar 10c is pivotally mounted to the rear surface of the vehicle via appropriate bearings 11 and 12, and a horizontal bar 10c is pivotally mounted to the upper ends of the front and rear legs 10a and 10b.

Reference numeral 13 denotes a stopper for restricting rocking protruding from the front right side surface of the vehicle chassis 6a, and is a stopper for restricting rocking that extends from the rear surface of the front leg portion 10a and the horizontal bar 1.
They are in contact with the lower surface of the door opening prevention frame 10 to restrict the upright state and tilted state of the door opening prevention frame body 10, respectively.

Reference numeral 14 denotes a tension spring installed between the tip of an arm 14a fixed coaxially with the pivot point of the front leg 10a and the front force section of the chassis 6a, and constantly biases the door opening prevention frame 10 in the upright direction. ing.

Reference numeral 15 denotes a driven member provided at a pivot point 10b' on the back surface of the vehicle chassis 6a of the rear leg section 10b, and a pair of left and right swing arms 15a and 15b fixed coaxially with the pivot point 10b';
It extends from a horizontal driven body i5c rotatably supported at the tips of both arms 15a and 15b.

The driven body 15c is made from one round bar, and the left and right
A small diameter concave portion 15C3 is formed in the center via the right gradually decreasing taper portions 15C□ and 15c2.

16 is a frame drive mechanism, which is installed in a small pit P' provided in a pit P for inserting the chassis 6a at the vehicle entry position 8;
It is opened from the operating cylinder 16a installed on the floor of the small pit P'.

The actuating cylinder 16a has a pushing member 16c fixed to the tip of the plunger 16a which expands and contracts in the front-rear direction.

The pushing member 16c is formed into a slightly elongated shape and has a tapered portion 16C2 by chamfering the left and high angles of the vertical surface 16C□ at the waist end.
16C3, and has a convex shape that can fit into the concave portion 15C3.

Next, the effect will be explained.

The frame drive mechanism 16 is currently maintaining the plunger 16b of the actuation cylinder 16a in the shortened state.

Therefore, the opening prevention frame 10 of each cage 6 has a tension spring 14.
It is maintained in an upright position by the spring force.

From this state, when the desired cage 6 stops at the vehicle entry position 8 as shown by the solid line in FIG. 15C and the pushing member 16c begin to engage with each other.

At this time, even if the stop position of the cage 6 is slightly shifted to the left or right from the predetermined position, the taper portion 15 cm-
The chassis 6a moves toward a predetermined position due to the mutual collision of the 16C2 or 15C2"16C,li.

Then, as the plunger 16b further extends, the door opening prevention frame 10 begins to tilt, and when the horizontal bar 10c comes into contact with the stopper 13, the extension operation of the plunger 16b is stopped and the frame tilting operation is completed. , the cage 6 is firmly positioned by the reaction force of returning to the position immediately after stopping.

From this state, the driver enters and takes the vehicle W into and out of the cage 6, but not only when entering the garage by pushing the cage 6 toward the cylinder 16a, but also when leaving the garage in the opposite direction, The reaction force of the cage 6 returning to its original position prevents the cage from swinging, allowing the driver to enter and exit the vehicle W safely and with peace of mind.

When the group of cages 6 is to be circulated again after the vehicle W enters and leaves the garage, if the plunger 16b is shortened by deactivating the actuating cylinder 16a, as the pushing member 16c retreats,
The repulsive force of the tension spring 14 causes the door-opening prevention frame 10 to rise to its original position, and the pushing member 16C moves forward away from the driven body 15c.

In the above-mentioned embodiment, the driven body 15c and the pushing member 16c were formed to have a concave shape and a convex shape, respectively, but as shown in FIG.
Even if c is formed into a concave shape, it can be carried out in exactly the same way.

In addition, as another embodiment, as shown in FIGS. 5 and 6, the driven member 215 has a driven plate 215c fixed to the pivot portion 10b', and a tapered recess is formed on the surface of the driven plate 215c. A push roller 216C is formed at the tip of the plunger 216b of the actuating cylinder 216 as a push member so as to be rotatable about the left and right horizontal axes.
The pushing roller 216c is attached to the groove 215C□
It is also possible to form the convex circumferential surface so that it can fit into the convex surface.

Furthermore, the concave groove 215C and the pushing roller 216c with the convex circumferential surface of the embodiment shown in FIGS. A push roller 316c may also be used.

As detailed above, in the parking equipment of the present invention, the abutting portions of the cage side member and the fixed floor side member can be engaged with the concave and convex portions of the device by using the tilting device of the door opening prevention frame body.
The tilting operation of a door-opening prevention frame and the prevention of rocking of a cage, both of which are necessary when entering and exiting a garage, can be performed in one operation, and an inexpensive parking facility is provided that has a simple structure and has two functions.
