Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lifting device for a gate rod installed at the entrance/exit of a parking lot.

[Conventional technology]

Conventionally, in the parking lots of apartment complexes such as condominiums, gate rods have been erected at the entrances of parking lots to prevent others from using the parking lots without permission. The structure was designed to prevent the entry of

When parking one's own car, the driver had to push aside the gate rod and drive the car into the parking lot, but this was a very time-consuming task, especially on rainy days.

Therefore, as described in Japanese Patent Application Laid-Open No. 58-80070, a parking lot where a gate bar (same as a gate rod) installed at the entrance of the parking lot is slid up and down using a friction wheel installed outside. The lifting device for the gate bar was damaged.

[Problem that the invention attempts to solve]

However, in the lift device for a gate bar in a parking lot described in JP-A No. 58-80070, the motor that is the drive source is installed outside the rod, and when in use, it is buried in the soil. Therefore, there was a problem in that a special case was required to prevent water from entering the inside.

Furthermore, since a heavy automobile passes through the upper part, the case body housing the drive source such as the motor needs to be made of a strong material.

This invention was developed in view of these circumstances, and is a parking lot gate rod that does not require a special case to store the motor, and the motor that is the drive source does not get submerged in water even when it rains. The purpose is to provide a lifting device for

[Means for Solving the Problems] A gate rod lifting device for a parking lot according to the present invention in accordance with the above object is a lifting device for a gate rod that is installed at the entrance/exit of a parking lot so that it can be raised and lowered, and the gate rod is provided with an airtight lid on the top. A motor is disposed in the upper part of the cylinder, and an elevating means is connected to the output shaft of the motor, and the parking lot is located in or near the parking lot and is driven by a sensor. The motor is driven by a signal from a control device to raise and lower the gate rod.

Here, the elevating means may be any means as long as it raises and lowers the gate rod, and specifically, it may be any means that can be used to raise and lower the gate rod, and specifically, it can be any means that includes a male screw connected to the output shaft of the motor and a female screw fixed in a predetermined position via a support member. The present invention is applicable to either a motor or a pinion connected to a motor and a fixed rack.

[Effect]

The parking lot gate rod lifting device according to the present invention has a cylinder body with a sealing lid attached to the top and a driving motor at the top, so air accumulates inside and water flows from the bottom to the top. Therefore, it is possible to prevent the motor from entering.

Furthermore, since the motor that lifts and lowers the gate rod is raised and lowered by signals from a control device that is driven by a sensor installed in or near the parking lot, it is possible to move the gate rod up and down in accordance with signals from a control device that is driven by a sensor installed in or near the parking lot. This means that the gate rod can be raised and lowered.

〔Example〕

Next, an embodiment embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

Here, FIG. 1 is a side sectional view of a lift device for a gate rod in a parking lot according to an embodiment of the present invention, FIG. 2 is a sectional view taken along arrow A-A in FIG. 1, and FIG. It is a sectional view taken along arrow BB in FIG.

As shown in FIG. 1, a lift device 10 for a gate rod in a parking lot according to an embodiment of the present invention includes a cylinder 11 with a circular cross section constituting the gate rod, and a cylinder 11 disposed on the top of the cylinder 11. A female screw 1 consisting of a motor 12, a male screw 13 driven by the motor 12, and a ball screw that meshes with the male screw 13.
4, a support cylinder 15 that supports the female screw 14, and an overall outer case 16. These will be explained in more detail below.

The cylinder 11 is made of a cylindrical pipe, and a sealing lid 17 is attached to its upper end. The sealing lid 17 is attached using screws (not shown) and can be removed as necessary. An arcuate locking portion 17a is formed at the top of the sealing lid 17, and a chain 17b is fixed thereto.

A motor 12 is attached to the lower part of the upper end of the cylindrical body 11 via a seat plate 18, and an output shaft 19 of the motor 12 is connected to a male screw 13 via a coupling 20.

A female screw 14 made of a ball screw is screwed into the male screw 13.
5 to the bottom of the outer case 16.

A cord reel 21 is attached to the upper end of the support tube 15, and the cord reel 21 has a spring mechanism inside to apply a certain tension to the cord 22 connected to the motor 12. It is designed to be able to maintain its condition.

A lower cord (not shown) of the cord reel 21 passes through a tube 23 made of a synthetic resin pipe, is wired underground, and is connected to a control device 24 disposed in or near the parking lot. This control device 24 is provided with an infrared light receptor, and when the control device is actuated by an operation device having an infrared light receptor that generates a signal (not shown), the motor 12 rotates forward or reverse, thereby forming the gate rod. The cylindrical body 11 is designed to move up and down.

In addition, as shown in FIGS. 2 and 3, in this embodiment, the outer case 16 has a rectangular cross section, and the cylindrical body 11 is cylindrical, and the cylindrical body 11 is arranged slightly eccentrically. Therefore, an angle member 25 is provided as a guide for the cylinder 11.
1 guide.

When using this parking lot gate rod lifting device 10, first arrange the parking lot gate rod lifting device 10 at the entrance of the parking lot so as to face each other, connect it with a chain 17b as necessary, and then connect it with the control device 2.
4 etc. and perform the prescribed wiring.

Then, by operating an actuator that, when used, can send a signal to the control device 24.
A predetermined signal is sent to the control device 24 to rotate the motor 12.

When the motor 12 rotates forward, the male screw 13 rotates, and the thrust of the male screw 13 causes the motor 12 to rise together with its cylindrical body 11. In addition,
Limit switches (not shown) are attached to the upper and lower limits of the cylindrical body 11, so that the cylindrical body 11 is stopped when it rises or descends to a predetermined position.

If the cylindrical body 11 of the lift device 10 of the gate rod in the parking lot is raised, cars etc. will not be able to enter the parking lot, and if the cylindrical body 11 is lowered, the upper airtight lid 17 will be closed. It reaches the ground level, allowing cars to pass over it.

In this case, since the upper part of the cylindrical body 11 is sealed, air is trapped inside and the motor 12 is not immersed in water from the outside.

[Effect of idea]

As is clear from the above explanation, the parking lot gate rod lifting device according to the present invention can lift and lower the cylindrical body that becomes the gate rod from the outside.
For example, you can raise and lower the cylinder while riding in your car, even in the rain.

Furthermore, since the motor that drives the cylindrical body is disposed inside the cylindrical body and the upper part is sealed, the motor, which is the driving source, will not be submerged by rain or underground water.

In addition, since it does not require a large exclusive area as a whole, the construction work can be carried out more easily than conventional methods.
