2, a drum 13 rotatably attached to the column 12 with its axis extending in the lateral direction, and a constant force spring 14 wound around the drum 13 and having its tip fixed to the upper part of the outer cylinder 11. ing. Thus, the pillar body 12 that is vertically inserted into the outer cylinder 11 is immersed in the outer cylinder 11 with the constant load spring 14 extended, and is fixed as the pillar body 12 is raised above the ground. The load spring 14 is wound around the drum 13.
This winding force is always constant, and the column body 12 is lifted by the force obtained by subtracting the winding force from the total weight of the column body 12.
Further, it is immersed in the ground by the force obtained by subtracting the capacity of the constant force spring 14 from the total weight of the column 12.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The "gate bar lifting device for a parking lot" of Japanese Patent Publication No. 126417 has the following problems. If the cylinder 1 is raised when the motor 2 cannot rotate, the vehicle cannot move in or out. At the time of power failure, it takes time to lower the cylinder 1 due to the screw type, and it is impossible for women. If a person is riding on the cylindrical body 1, it is dangerous to operate it unexpectedly. Since the power supply lead wire to the motor 2 expands and contracts, it is easy to break. Since the motor 2 is placed in the cylindrical body 1, the size is large (large diameter). Friction resistance is high because it is lifted and lowered by screws. In addition, the "column body that can be freely retracted to and from the ground" in Japanese Utility Model Laid-Open No. 2-29915 does not have an active means for lowering the column body 12 and is manpowered. There is a problem that it requires labor.

[0004]

In order to solve the above-mentioned problems, the present invention has a pole guide embedded and fixed in the ground, and a pole vertically inserted into the pole guide. Side constant load spring having a constant load spring winding drum attached to an upper portion of the pole guide and a constant load spring wound at the constant load spring winding drum and having a tip end fixed to a lower portion of the pole. A device is provided, and a wire winding electric drum for winding a wire is provided in the vicinity of the upper portion of the pole guide, and is provided at a lower portion of the pole guide between the lower portion of the pole and the wire winding electric drum. Connecting the wire in the direction of pulling down the pole through the wire receiver, thereby rewinding the wire wound on the wire winding electric drum. Therefore, it is intended to provide an electric parking lot pole lifting device capable of raising the pole and lowering the pole by winding the wire on the wire winding electric drum. .

[0005]

The operation of the present invention is as follows. By rewinding the wire wound on the wire winding electric drum, the pole rises only by the force of the constant load spring wound on the fixed side constant load spring winding drum. The pole is lowered by winding the wire around the wire winding electric drum. The winding load of the wire winding electric drum is a force obtained by subtracting the weight of the pole from the winding force of the constant load spring, is constant (constant load) over the entire stroke, and may be a small capacity motor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electric parking pole lifting device according to the present invention will be described below with reference to FIG. The electric parking pole lifting device according to the present invention has a pole guide 21 embedded and fixed in the ground and a pole 22 vertically inserted into the pole guide 21, and is provided above the fixed-side pole guide 21. A constant load spring device including an attached constant load spring winding drum 23 and a constant load spring 24 wound around the constant load spring winding drum 23 and fixed at the lower end of the pole 22 to the pole guide 21 is provided. A wire winding electric drum 26 for winding the wire 25 is provided close to the upper part of the wire, and a wire receiver 27 provided under the pole guide 21 is provided between the lower part of the pole 22 and the wire winding electric drum 26. The wire 25 is connected in the direction of pulling down the pole 22, so that the wire 25 wound on the wire winding electric drum 26 can be unwound. It is possible to increase the pole 22 by wire 2 to the wire winding electric drum 26
The pole 22 can be lowered by winding up 5. The electric parking pole lifting device according to the present invention operates as follows. The pole 22 which is vertically inserted into the pole guide 21 is retracted in the pole guide 21 in a state where the constant load spring 24 is extended. As the pole 22 is raised above the ground, the constant load spring 24 is wound by a constant load spring. It is wound around the take-up drum 23. This winding force is always constant, and the pole 22 is lifted by the force obtained by subtracting the winding force from the total weight of the pole 22. or,
The pole 22 is immersed in the ground by a force obtained by subtracting the capacity of the constant force spring 24 from the total weight of the pole 22. The pole 22 rewinds the wire 25 wound on the electric wire winding electric drum 26, so that the constant load spring winding drum 2 on the fixed side is rewound.
3 rises only by the force of the constant force spring 24 caught in 3,
Also, the wire 25 is lowered by winding the wire 25 around the wire winding electric drum 26. Wire winding electric drum 2
The winding load of No. 6 is due to the winding force of the constant force spring 24
With a force less the weight of, the motor is constant (constant load) over the entire stroke, and a small capacity motor may be used. Paul 2
When 2 is raised, the wire winding electric drum is in an unloaded state.

[0007]

Since the electric parking pole lifting device according to the present invention is constructed as described above, it has the following effects. Since the lifting force of the pole is increased by a slight force obtained by subtracting the weight of the pole from the winding force of the constant force spring device, the winding load of the motor when the pole is lowered is small, and power saving (small motor) is possible. Automation can be realized. Since the pole is lifted only by the force of the constant force spring, it can be operated with low power consumption, and since the lifting force is small as described above, it does not hurt an object or a person. Since the pole can be lowered and locked with a light force at the time of a power failure or a failure, it is possible to minimize obstacles when the vehicle comes in and out.
