Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a two-stage parking device that can park automobiles one above the other.

(Prior art) Conventional two-stage parking systems include those in which a second-stage parking frame material is provided above the parking area of the first stage, which is raised and lowered by hydraulic cylinders installed at the four corners; As in No. 24137, it has been proposed to pivot the tip of a parking frame material to the upper end of a support column and push it up with a hydraulic cylinder to park in two levels.

However, in the former case, the hydraulic cylinder mechanism is complicated, and the hydraulic pump that supplies and discharges pressure oil to the hydraulic cylinder mechanism is also large, resulting in a complex structure as a whole. In some cases, it is buried in the parking lot, which raises the problem of high manufacturing costs.In the latter case, the second-tier parking frame material cannot be raised and lowered in a horizontal state, so if there is cargo on the car, the cargo may shift. In addition, due to its structure, the point of action is close to the fulcrum, so the output of the hydraulic system becomes large.

In addition, a two-stage parking device as shown in Japanese Patent Application Laid-Open No. 55-65671 has been devised and put into practical use by the applicant of the present application, but in this device, the tips of the pillars and frame materials are simply removed. Due to the pivot connection using the connecting member, the angle of inclination for entering the parking frame member is steep, and the problem remains that the frame member cannot be raised or lowered in a horizontal state.

(Object of the Invention) The present invention has been made to solve a series of problems mentioned above, and has a simple structure, a small inclination angle for entering the second-tier parking frame material, and
Furthermore, the present invention aims to provide a two-stage parking device that can be raised and lowered in a nearly horizontal state and requires only a small output from a power unit.

(Structure of the Invention) The above object is to plant two pillars facing each other from the ground with a distance larger than the width of the automobile;
A middle portion of a frame-shaped arm member is pivotally attached to the rear end portions of the two pillars, and a middle portion of a parking frame member on which a car is mounted is pivotally attached to the rear end portion of the arm member. , a holding material welded to the tip of the parking frame material and a protruding material welded to the upper part of the upright part of the pillar are each pivotally connected by two connecting rods to form a substantially parallel link, the pillar, A link mechanism is formed by the arm material, the parking frame material, and the connecting rod, and an electric winch is attached to the base member of the pillar, and the wire rope wound around the electric winch is connected to the tip of the arm material. This is achieved by a two-stage parking system characterized in that it spans between sheaves that are pivotally connected to the base members of the pillars.

(Embodiment) A first embodiment of the present invention will be described based on FIGS. 1 to 3. Two foundation members 1 are provided in parallel on the ground at a distance slightly larger than the width of an automobile. Column base members 2 whose upper portions extend rearward are welded to the upper part of each of the base members 1 in parallel to each other, and support members 3a are welded to the column base members 2 to form columns 4. 3b is two foundation members 1, 1
This is a connecting material welded in between.

At the rear end of this column 4, arm members 5 are provided.
The arm member 5 is pivoted at its midpoint by a shaft 6, and the distal end portions of the arm member 5 are connected by a connecting member 7, so that the arm member 5 is formed into a frame shape. An intermediate portion of a parking frame member 8 on which a car is mounted is pivotally attached to the rear end portion of the arm member 5 by shafts 9, 9. A stopper 8a is provided at the front of the parking frame member 8, into which the front wheel of a parked car is inserted.
On the other hand, a protrusion 10 is installed at the base of each of the pillars 4, and two connecting rods 12 are installed between each of the four connecting rods 12 and a retainer 11 installed at the front corner of the parking frame 8. are suspended parallel to each other, with axes 12a and 12a, respectively.
12b, 12c and 12d are pivotally connected to form substantially parallel links. The support column 4, the arm member 5, the parking frame member 8, and the connecting rod 12 form a link mechanism as a whole. In this link mechanism, the arm member 5 and the connecting rod 12 rotate in synchronization, and the parking frame member 8 is moved up and down while maintaining a state substantially parallel to the ground.

A reversible electric winch 13 is attached to the front part of the base member 1. A base end of a wire rope 15 is locked to a drum 14 attached to an output shaft (not shown) of the electric winch 13. After this wire rope 15 is wound around this drum 14 once or several times, the arm material 5
Sheave 16 is pivotally attached to the tip of the arm member 5, sheaves 17 and 18 are pivoted to the front of the base member 1, and sheave 19 is pivotably attached to the tip of the arm member 5.
After the sheave 18 is successively crossed, the tip is locked to the shaft end of the sheave 18 which is pivotally attached to the tip of the base member 1. (See FIG. 4) As shown in FIG. 3, the parking frame member 8 is formed to be slightly wider at the rear. This is intended to make it easier for motor vehicles to travel. Further, an operating switch 20 of this two-stage parking device is attached to the rear end corner of the parking frame member 8.

How to use the two-stage parking device configured as described above will be explained. First, as shown in FIG. 1, with the rear end of the parking frame member 8 in contact with the ground, the vehicle 21 is driven to a position where the front wheels of the vehicle 21 come into contact with the stopper 8a and placed on top of the stopper 8a. Next, the driver gets out of the car and operates the operating switch 20 located at the rear end corner of the parking frame member 8. As a result, the electric winch 13 is operated and the wire rope 15 is wound around the drum 14, so that the arm member 5 rotates counterclockwise about the shaft 6 as a fulcrum.

When the arm member 5 rotates counterclockwise, the connecting rod 12 rotates in synchronism with the rotation of the arm member 5 to rotate the shaft 12 on the protrusion member 10 side.
By rotating around a and 12c, the parking frame member 8 rises while maintaining a state substantially parallel to the ground. As a result, the parking frame material 8 becomes
When the electric winch 13 rises to the position shown in FIG. 5, the operation of the electric winch 13 is stopped by a limit switch (not shown). Another car 22 is parked below the parking frame member 8.

Next, when lowering the car 21 placed on the parking frame material 8, first the lower car 21
When the electric winch 13 is retracted and then the electric winch 13 is rotated in the opposite direction to that described above, the wire rope 15 gradually unravels and the arm member 5 rotates clockwise about the shaft 6 as a fulcrum. The connecting rod 12 also rotates clockwise accordingly, and the parking frame member 8 descends while maintaining a substantially parallel state, returning to the state shown in FIG. 1. The car 21 can therefore be lowered onto the ground.

6 and 7 show a second embodiment of the present invention.

In this example, the car 2 parked in the lower row
The same components as those in the first embodiment are given the same reference numerals and their explanations will be omitted.

In order to satisfy the above conditions, in this embodiment, the pillar 2
3 is formed into a semicircular shape, and a rail material 24 is provided below the parking frame material 8 and extends in a direction perpendicular to the vertical direction of the parking frame material 8. A frame member 25 is placed on the frame member 25, which rolls along the frame member 25.

This frame material 25 is connected to a roller 2 that rolls on a rail material 24 laid on the rear end of the foundation member 1.
6, 27 and rollers 28 that roll on the ground.

In this case, when lowering the car 21 placed on the parking frame material 8 onto the ground, the lower car 22 is moved horizontally along the rail material 24 without running. The lower part is left empty and the car 21 can be unloaded.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects.

The structure is extremely simple and can be manufactured at low cost.

The inclination angle for getting into the car is small, and the arm material is frame-shaped, making it easy to get into the car.

Since the parking frame material can be raised and lowered in a nearly horizontal state, the cargo of the parked car does not roll, and no strain is placed on the parked car.

Since it is a lever type, the output of the power mechanism can be small.
