Description

Description: TECHNICAL FIELD The present invention relates to a slide type automatic opening / closing gate, in which a wheel attached to the gate is driven by a battery, and is provided on a gate pillar or a fence at a rear portion of an opening position of the gate. It is characterized in that the battery is charged by the provided charger.

[Prior art]

In the conventional sliding automatic opening / closing gate, when driving the self-propelled wheels attached to the lower end of the gate, a 100V AC power supply was used and the wheels were driven via a motor. Therefore, the power cord required for driving the motor must be stretched between the outlet installed on the gate pole and the motor of the self-propelled wheel fixed to the gate, and this power cord does not hang down on the ground when the gate is opened or closed. I needed to expand and contract.
For this reason, conventionally, it has been necessary to wind a cord around a reel that can be automatically wound and to use a tension mechanism that uses a pulley to prevent the cord from hanging. In addition, the actual development Sho 62-
In the rechargeable self-propelled electric door described in Japanese Patent No. 34074, the battery and the charger are attached to the frame of the gate, and when the gate is fully opened (fully closed), it is fixed to the charger on the gate side and the gate post side. It is charged by connecting to the AC power supply.

[Problems to be Solved by the Invention]

In the above-mentioned conventional method, the cord holding mechanism that expands and contracts in accordance with the opening and closing of the gate is complicated, and the cord is severely damaged, resulting in an unsightly appearance.
Therefore, a cordless type automatic opening / closing gate has been strongly desired. Therefore, it is possible to use a battery, but if the gate is heavy or the frequency of opening and closing is high, a lot of power is used, so it is necessary to carry the charger near the gate and charge it frequently, so it is practical. It's easy to imagine that it will be poor. As a precaution, the present inventor has used a 12V6Ah battery (YUASA-NP6-12:
Using a product name: Yuasa Battery Co., Ltd., we tested a gate with a weight of 80 kg driven by one self-propelled wheel, and it stopped after 6 reciprocations at a distance of 2,9 m. . It is very inconvenient to perform supplementary charging every six round trips, and it takes a considerable amount of time to fully charge a nearly exhausted battery, which proves to be impractical. Was done. In addition, in the rechargeable self-propelled electric door, the weight of the gate is used to press the tire strongly against the floor surface with a spring or the like. Therefore, the wheel supporting the gate is made of steel or a hard tire having large uneven grooves in consideration of the friction resistance with the floor surface or the guide rail. Since such wheels move on the floor and guide rails, the gate reciprocates while vibrating on the floor and guide rails, and the whole gate vibrates each time the gate is opened and closed.
There is a possibility that disconnection or connection failure may occur at the connection part between the battery and the charger provided at the gate or the connection part between the charger and the contact for taking in the external power source. further,
When the charger is connected to an external power supply (usually AC 100V) when there is some connection failure in the wiring or when rainwater is entering, the problem that the external power supply voltage is applied to the gate due to electrical leakage There was a point.

[Means for Solving the Problems]

The present invention has solved the above-mentioned problems, and the cord between the self-propelled wheel and the power outlet is omitted, and the self-propelled wheel is of a battery-driven type, and supplementary charging for this battery is performed at the closed position or the open position of the gate. It is designed so that it can be automatically and constantly operated from the charger installed on the gate pillar or fence at the position.

That is, the sliding automatic opening / closing gate according to the present invention is provided with a self-propelled wheel including a battery and a motor, and driving a wheel by the motor, at the front end, the rear end, or the front and rear ends of the sliding opening / closing gate. A joint terminal that communicates with both + and − terminals of the battery is provided at the front, rear, or both of the front and rear of the battery, and a charger having a terminal connectable to the joint terminal of the battery at the closed position or the open position of the gate is provided on the gate pole. It is characterized in that a terminal of the charger and a joint terminal of the battery are provided inside or inside or at a rear portion of an open position of a gate in association with each other.

Note that the slide type gate may be one that slides to the left and right to open and close, and includes a single door as shown in the figure and a continuous door or an accordion gate.

In addition, it goes without saying that the battery can also be used in combination with a solar cell.

[Action]

In the present invention, when the gate is closed, the joint terminal provided in front of the self-propelled wheel fixed to the front end of the gate,
It comes in contact with the terminal of the charger fixed to one of the gate posts to perform supplementary charging. On the contrary, when the gate is opened, the joint terminal provided at the rear of the self-propelled wheel or the joint terminal provided at the rear of the self-propelled wheel fixed to the rear end of the gate is the other gate pillar or the rear of the self-propelled wheel. By contacting the terminal of the charger provided corresponding to, supplementary charging is performed.

Therefore, when opening or closing the gate, the battery for driving the motor of the self-propelled wheel is always fully charged, so even if the gate is heavy or the frequency of opening and closing is high, it is always reliable. It can be opened and closed easily. Also,
Since the charger is attached not to the gate side but to the gate pillar side, wiring for connecting the battery and the charger in the gate is not required, and it is possible to suppress disconnection and connection failure due to gate vibration. Further, the voltage applied by the charger is 100 V AC to DC voltage (usually DC 12 V
Since it is a voltage converted to V), this converted voltage is applied to the gate even if there is a leakage due to poor connection of the charger terminal etc. or entry of rainwater when connected to an external power source, Even if the gate is touched, there is no risk of burns or shock death due to electric shock, and safety can be guaranteed.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, the gate pillars are erected at regular intervals, and a gate with self-propelled wheels is provided at the lower end so as to block between the gate pillars. The self-propelled wheel is a box type with a built-in battery and a motor, and is provided so that a part of the wheel is exposed from the lower part of the box, and in the illustrated example, it is fixed to the front lower end of the gate, In front of this self-propelled wheel, a projecting joint terminal is provided which communicates with the + and-terminals of the internal battery.

Is an extension cord that extends backward from the +/- terminal of the battery of the self-propelled wheel, is embedded in the hollow horizontal frame of the gate constituent member, and extends to the joint terminal fixing plate at the rear end of the gate. Joint terminals are also projected on the rear surface of the fixing plate. In addition, is a driven wheel provided on the rear lower surface of the gate.

Is a charger that is embedded and fixed in the interior of the gate, and this charger is always supplied with electric power and is always chargeable. A terminal connectable to the joint terminal faces the front surface of the charger, that is, the surface facing the self-propelled wheel. Therefore, when the gate is closed as shown in the drawing, the joint terminal on the self-propelled wheel side is automatically coupled / contacted with the terminal of the charger to start supplementary charging.

Is a charger installed at the rear of the rear end of the gate, and when the gate is fully opened, it is fixed to the back surface of the fence where it is connected and comes into contact with the joint terminal that protrudes rearward. As in the above, the battery is always in a chargeable state.

In addition, it is natural that the terminals of the charger and the joint terminals of the self-propelled wheels have a waterproof and dustproof structure,
As a joint means between both terminals, it is preferable to use a magnet type.

Therefore, when the gate is opened, the joint terminal, which is provided so as to project to the rear of the gate, is combined and brought into contact with the terminal of this charger to start supplementary charging.

Therefore, when opening and closing the gate, the battery is always fully charged, so even with a heavy gate,
Even when the frequency of opening and closing is relatively high, the gate can always be reliably opened and closed. Furthermore, since the charger is installed on the gate pillar and the fence, the connection between the battery and the charger at the gate is not required, so it is possible to suppress the disconnection and connection failure due to the vibration of the gate and the charger terminal. The external power supply voltage will not be applied to the gate as it is even if there is a leak due to poor connection such as the above, or the entry of rainwater.

In the above embodiment, one self-propelled wheel is provided at the front end of the gate, but it may be provided only at the front and rear ends or at the rear end depending on how the gate is used, and it may be extended. The joint terminal by cord may be omitted. Further, the charger may be fixed to the inside of the gate pillar without being embedded in the gate pillar, and its position and mounting form are not particularly limited.

〔The invention's effect〕

As described above, according to the present invention, when the gate is opened and closed, the battery is always recharged, so that opening / closing can be reliably performed even in the case of a gate having a large weight and a gate having a high opening / closing frequency.

In addition, since an extension power cord for driving the self-propelled wheels is not required, it is smart in appearance and is extremely practical. Further, since the charger is provided not on the gate side but on the gate pillar side, wiring for connecting the battery and the charger in the gate is not required, so that it is possible to suppress disconnection and connection failure due to vibration of the gate. Since the voltage applied to the gate will be low even if electrical leakage occurs due to poor connection of charging terminals or the entry of rainwater, the risk of electric shock can be minimized, so the gate is extremely safe. Can be provided.
