Description

[Detailed Description of the Invention] The present invention relates to an automatic gate that opens and closes electrically.

In general, gates are often opened and closed manually and locked from the inside. However, many gates can be unlocked by inserting a hand from the outside, which poses security problems. Also, if the gate is far away from the house, the family member has to go out and open the gate every time a visitor comes or goes home, especially if the gate is heavy.
It was troublesome for the elderly and children.

The present invention was developed in consideration of this point, and allows the gate to be opened and closed automatically and reliably by remote control.
The object of the present invention is to provide an automatic gate that cannot be opened manually from the outside.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 show one embodiment of the present invention. In the figures, 1A and 1B are gate posts erected at intervals on the left and right. Shafts 2A, 2B are supported by pillow blocks 3... Gates 4A, 4B are supported on the left and right vertical shafts 2A, 2B so as to be openable and closable inward, and ohm gears 5A, 5B are attached to the lower ends of the vertical shafts 2A, 2B, respectively.

6 is a U-shaped pit provided on the ground 7 perpendicularly to both gateposts 1A and 1B, and a cover plate 8 is placed over the top.
A horizontal shaft 9 is provided horizontally within the pit 6, and its intermediate portion is inserted into a protective pipe 11 fixed by a pillow unit 10 and is rotatably supported. On the end side of the horizontal shaft 9 protruding from the protection pipe 11, the ohm gears 5A, 5B are installed.
The vertical screw ohms 12A and 12B that mesh with the screws are fixed by spills.

Further, a horizontal shaft 9 extending laterally from the gate post 1A on the front side is connected to a deceleration motor 14 via a joint fitting 13, and this deceleration motor 14 integrates a motor capable of forward and reverse rotation and a deceleration mechanism. It is connected to a button switch 15 via a control mechanism installed indoors to control forward and reverse rotation operations.

Further, one bevel gear 16a is attached to the shaft end of the deceleration motor 14, and this bevel gear 16a is adapted to mesh vertically with the other bevel gear 16b attached to the lower end of a shaft 18 supported by a column 17.
This shaft 18 has a pin hole 19 drilled in the middle thereof, a handle 20 is attached to the upper end, and is supported by a support bracket 21 on the column 17 so as to be able to move up and down and freely rotate. A pin is inserted into the lifting pin hole 19 and fixed upward to separate the umbrella wheels 16a and 16b.

22A, 22B are inside both gates 4A, 4B,
Gate 4A,
When closing 4B, the opposing gates 4A and 4B are pressed against each other by presser plates 22A and 22B.

Reference numerals 23a and 23b are limit switches attached to one gate post 1A, which stop the deceleration motor 14 when they come into contact with each other when the gate 4A is opened or closed.
23c, 23d, 23e, 23f, 23g, 23
Reference numeral h denotes a limit switch provided on the abutting surface and the bottom surface of the gates 4A and 4B, respectively, and is designed to similarly stop the deceleration motor 14 when the gates come into contact with an obstacle.

24A and 24B are stopper pillars, and gateposts 1A and 24B are stopper pillars.
It is built on the premises on the front side of 1B, and one gate 4
Gate A is shifted in position so that it opens at a larger angle than the other gate 4B.

Next, the operation of the automatic gate having the above structure will be explained.

When you turn on the button switch 15 installed indoors,
The deceleration motor 14 rotates, and the horizontal shaft 9 connected thereto also rotates. At this time, the ohm gear 5A, which meshes with the ohms 12A and 12B of the horizontal shaft 9,
5B rotates, and the left and right gates 4A and 4B attached to the vertical shafts 2A and 2B open at the same speed.
First, the right gate 4B comes into contact with the stopper pillar 24B and stops. On the other hand, the left gate 1A, which has a larger opening angle, comes into contact with the stopper post 24A with a slight delay, and at this time also contacts the limit switch 23a attached to the gate post 1A, so that the deceleration motor 14 is stopped.

In this case, the gate 4B is placed first on the stopper pillar 2.
Although the horizontal shaft 9 continues to rotate even when it comes into contact with the ohm 4B and stops, the ohm gear 5B and the ohm 12B are slightly engaged with each other, so that the twist caused by the rotation can be absorbed.

Also, when closing the gates 4A and 4B, when the button switch 15 is turned on again, the deceleration motor 14
rotates in the opposite direction, and both gates 4A and 4B close at the same speed. This state is shown in Fig. 3. As shown in Fig. 3, the gate 4B with a small opening angle moves forward and closes, as shown in Fig. 3A, and then, as shown in Fig. The board 24A pushes the gate 4B,
The push plate 24B closes while pushing the gate 4A together, and the gate 4A contacts the limit switch 23b, stopping the deceleration motor 14.

In this case, since the push plates 24A and 24B are attached, even if there is a discrepancy in the speed or stop position of both gates 4A and 4B, since the opening angle is large, they will be simultaneously pushed by the push plate 24A of the gate 4A, which will be closed later, and will be fixed. It can be closed in a securely aligned parallel position. Moreover, when the deceleration motor 14 is stopped, it is locked and cannot be opened, making it safer from a crime prevention standpoint.

Furthermore, if the gates 4A, 4B hit an obstacle such as a person when opening or closing, the limit switches 23c to 23h automatically operate to stop the deceleration motor 14, providing excellent safety.

In addition, in the event of a power outage, the pin of the shaft 18 is removed and the bevel gear 16b at the lower end and the bevel gear 16 at the end of the shaft are removed.
It can be opened and closed manually by engaging the handles a and turning the handle 20.

In the above embodiment, the limit switch 23a is attached to the gate post 1A, but it may be attached to the stopper post 24A side.

Further, the switch is not limited to a push button type switch, but may also be one that is operated by radio signals and can be opened and closed from outside while riding in the car.

As explained above, the automatic gate according to the present invention can be reliably opened and closed automatically by remote control, and since it cannot be opened manually from the outside, it is safe in terms of crime prevention, and has extremely practical value. It is excellent.
