Description

[Detailed description of the invention] The present invention relates to an intermediate cord connecting device for electric gates, and more specifically, to a device for connecting power cords when a long electric gate is constructed by connecting a series of gates. It is something.

The present inventor first developed a power cord winding device for an electric gate. Specifically, the inventor of the present invention first developed an electric gate power cord winding device. At the gate, a cord reel with a built-in spiral spring is stored in the box of the electric opening/closing device, and the tip of the cord is attached at the base end to the cord reel winding drum, and the midway part is attached to the diagonal frame member of the gate and the cord reel with a built-in spiral spring. We have devised a power cord winding device for electric gates, which is characterized in that the power cord is connected to a power switch attached to an external fixed body so that the power can be energized after passing through the support shafts that support the diagonal frame member (practical application). However, the present invention is a combination of the previous invention.

As mentioned above, electric gates have a cord reel stored in the box of the electric opening/closing device, so if the electric gate becomes longer, the cord will also become longer, and the cord reel to wind it will become longer. The diameter of the gate has also increased, making it impossible to store it inside the box, and the extension length (opening/closing length) of the gate has also increased.
Since the diameter of the cord reel had to be changed accordingly, it was not suitable for mass production, and there were problems such as increased costs.

The present invention has been made to eliminate such problems.

Therefore, an object of the present invention is to make it possible to use cord reels of the same diameter regardless of the length of the electric gate.

For this purpose, the present invention incorporates a receptacle having an input plug and an output plug electrically connected to each other on a base, a spiral spring, and a winding drum of the receptacle having an input plug and an output plug electrically connected to each other. A rotatable cord reel wound with an intermediate cord for electrical connection is provided, and this base is connected and fixed to the lower part between the gate and the vertical frames of the gate, and the free end of the intermediate cord is connected to the lower part of the gate. It is electrically connected directly or indirectly to a power switch, and the input plug of the outlet is electrically connected to the free end of a cord that connects to the gate opening/closing motor provided at the tip of the opening/closing side of the gate. That is.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

First, I will explain the outline of an electric gate with reference to Figures 1 and 2. 1 is two rails laid between the gate pillars that serve as a side entrance, and 2 is a gate that automatically runs on this rail 1. A gate that opens and closes a side entrance.
For example, this gate 2 is configured such that a large number of vertical frames 3 are connected by upper and lower diagonal members 4, 4', and pivot shafts 5 are inserted at their respective intersecting positions, so that the gates 2 can be expanded and contracted laterally, and A door wheel 6 is rotatably attached to the lower end of the vertical frame 3 at an interval position.

An electric opening/closing device 7 is movably connected to the tip of the gate 2 on the opening/closing side. Electric opening/closing device 7
As shown in FIG. 3, it has a motor 9 for opening and closing the gate housed in a box 8, and a cord reel 11 with a built-in spiral spring so that it can automatically wind up the cord 10. The rotation of the motor 9 is transmitted to the door roller 1 via a sprocket 12 and a chain 13.
The motor 9 and the cord reel 11 are electrically connected, and the cord reel 11 and one end of the cord 10 are also electrically connected.

Then, the free end of the cord 10 is passed through the diagonal member 4' of the gate 2 and the pivot 5, and then passed through the external fixed body 15.
electrically connected to a power switch 16 provided in the
By operating the power switch 16, the motor 9 in the electric opening/closing device 7 is rotated in forward and reverse directions to automatically move the gate 2, thereby opening and closing the side entrance.

In such an electric gate, when the gates are connected in series and become long, the length of the cord 10 also becomes long, and the diameter of the cord reel 11 that winds it also becomes large.

Therefore, a fourth
If the intermediate cord connecting means shown in the figure below is provided, the diameter of the cord reel will not increase even if the entire gate becomes long, and all cord reels with the same diameter can be used.

That is, in FIG. 4, a waterproof outlet 21 having an input plug 22 and an output plug 23 electrically connected to each other is fixed on the top of a vertically rectangular base 20, and this waterproof outlet On the base 20, which is the lower position of 21,
A cord reel 24 is rotatably supported.

This cord reel 24, as shown in FIG.
A spiral spring 26 is housed inside one side of the winding drum 25 with flanges formed at both ends, and one end of the spiral spring 26 is locked to a fixed shaft 27, and the other end is connected to a part of the inner surface of the winding drum 25. By being locked,
The intermediate cord 28 can be automatically wound onto the winding drum 25 with the restoring force of the spiral spring 26, and the winding drum 2
A disc-shaped electrically conductive plate 29 is rotatably fitted inside the other side of the electrically conductive plate 5 , and a disc-shaped power receiving plate 30 is arranged in parallel at the innermost position facing the electrically conductive plate 29 . fixedly provided in a concentric manner,
The conductive plate 29 and the power receiving plate 30 are electrically connected to each other, and the base end of the intermediate cord 28 and the conductive plate 2
9 is also electrically connected, and is also electrically connected to the power receiving plate 30 and the output plug 23 of the waterproof outlet 21.

The cord reel 24 has a fixed shaft 27 fitted into its axis, a base 20 for supporting the fixed shaft 27, a square bearing stand 31 provided on the base 20, and a bearing 32. It is rotatably supported via the shaft.

The free end of the intermediate cord 28 wound around the cord reel 24 is attached to the diagonal member 4' of the gate 2 and the pivot shaft 5.
The unwinding portion of the intermediate cord 28 on the base 20 is used to guide the unwinding and winding of the intermediate cord 28. A pair of guide rollers 33, 33 are rotatably protruded so as to sandwich the free end of the intermediate cord 28.

As shown in FIGS. 8 to 11, the base 20 is fixed to the lower part between the gate 2 and the vertical frames 3, 3 of the gate 2 adjacent to each other, via a connecting fitting 34.

That is, in the upper and lower parts of the base 20, there are bolt holes 35 drilled in the upper and lower four corners of the base 20, and shaped connecting metal fittings 3 that are arranged opposite to each other in the front and rear of the upper and lower parts of the base 20.
It is fastened and fixed by a bolt 37 and a nut 38 inserted into matching holes with the bolt holes 36, 36 of 4 and 34.

Furthermore, the input plug 22 of the waterproof outlet 21 has a cord 10 connected to the motor 9 of the electric opening/closing device 7 provided at the tip of the opening/closing side of the gate 2.
The free end of the cord is electrically connected via a cord stopper 39 provided on the base 20.

Although not particularly shown, a cover is removably provided on the base 20 to cover the waterproof outlet 21 and the cord reel 24 to prevent them from being affected by wind and rain.

In the illustrated embodiment, a case is shown in which two sets of gates 2, 2 are connected, but in a case where three sets of gates are connected, two
The input plug of the waterproof outlet connected between the second gate and the third gate is wrapped around the cord reel connected between the second gate and the gate with an electric opening/closing device. Of course, the free ends of the intermediate cords that are connected are electrically connected.

Next, to briefly explain the operation, when closing the gates 2, 2 from the open state as shown in FIG. When the cord reel 11 and the cord reel 24 move forward together with the electric opening/closing device 7, the rotation is transmitted to the door roller 14, and the cord reel 11 and the cord reel 24 move forward together with the electric opening/closing device 7.
(In the case of the cord reel 11, the numbers are omitted) The cord 10 and the intermediate cord 28, which are wound on the cord 10 and the intermediate cord 28, are moved forward by the cord 10 and the intermediate cord 28, which are wound on the spiral spring 26 (the numbers are omitted in the case of the cord reel 11). Due to the restoring force of (omitted), it moves forward with a moderate tension without sagging, and closes the side door.

When opening the door, operate the power switch 16 in the opposite direction to rotate the motor 9 in the opposite direction, and as the electric opening/closing device 7 moves backward, the cord reel 11 and the cord reel 24 will be placed on the winding drum again. The cord 10 and the intermediate cord 28 automatically wind up the entire amount under moderate tension without being pinched between the vertical frame 3 or each of the diagonal members 4 and 4' due to the restoring force of the spiral spring. and the side entrance will be opened.

However, according to the present invention, no matter how many gates are connected to form a long electric gate, the diameter of the cord reel will not increase correspondingly, and the cord reel will not increase in diameter correspondingly. The diameters of the cord reels for winding the cord may all be the same.

Therefore, there is no need to change the diameter of the cord reel to correspond to the length of the gate, so it can be mass-produced and provided at low cost. Even if a number of cords are connected, the tatami is approximately the same as the width of the cord reel, so there is almost no increase in tatami compared to the conventional manual type, and the appearance is good. It has the effect of increasing the product value.
