る。 Figures 1 and 2 are for explaining a conventional operation panel opening/closing device. Reference numeral 1 indicates an operation panel body installed on a wing wall in an elevator car room, and this body 1 is a frame. 2. A button plate 4 on which the car call buttons 3 are arranged, a lower plate 5, and a stopper plate 9 fixed to the back surface of the lower plate 5.
An opening surrounded by a frame 2, a button plate 4, and a lower plate 5 is formed on the front surface of the main body 1, and a hinge member 6 is formed on the back surface of the lower edge of the opening.
A horizontal hinge pin 6b is disposed, and a mounting portion of the hinge member 6 is fixed to the stopper plate 9. The hinge member 6 is provided with a U-shaped portion 6a,
The open end of one side of the U-shaped portion 6a is pivotally supported by the hinge pin 6b, and the portion protruding outward from the open end of the other side of the U-shaped portion 6a is the lower side of the door 7 that opens and closes the opening. Car operation switches (not shown) such as a car lighting switch, an elevator start/stop switch, etc., which are fixed to the back side of the edge, and which face the opening door 7, are installed inside the main body 1. Also, 8 is the opening door 7
This is a locking device that locks the upper end of the door in the closed state.

注意するという問題点があつた。 However, since the above-mentioned swing door 7 has a structure in which the back side of the lower edge portion is supported by the hinge 6 and opens from top to bottom about the horizontal hinge pin 66, the swing door 7 is caused by its own weight. When the hinge member 6 is opened horizontally, the U-shaped portion 6a of the hinge member 6 straddles the stopper plate 9 and collides with the back surface of the stopper plate 9, and the moment due to the own weight of the hinge member 6 is quite large. This may cause deformation of the connection part to the hinge member 6 or deformation of the screwed part of the hinge member 6, which may cause problems in opening and closing the door 7, and may also cause the door 7 to be in the wrong position when closed. There is a risk that it may become misaligned. Therefore, when opening door 7,
There was a problem in that it was necessary to place a hand on the door to open it, and that care had to be taken when handling it.

を提供することを目的とする。 This idea solves the above-mentioned conventional problems, and connects the upper and lower ends of the coil spring to the back side below the opening of the operation panel body and the U-shaped part of the hinge member. , by offsetting the moment due to the door's own weight with the coil spring, there is provided a door opening/closing device for an operation panel that does not cause deformation of the hinge member etc. even when the door is opened by its own weight, and is easy to handle. The purpose is to

ほとんど作用しない形態となつている。 3 to 5 show an embodiment of the operating panel opening/closing device according to this invention, where the same reference numerals as in FIGS. 1 and 2 indicate the same parts, and 10 is a tension coil spring. The upper end of this coil spring 10 is hooked to one side of the U-shaped portion 6a of the hinge member 6 to which the opening door 7 is connected, at the end opposite to the open end, and the lower end of the coil spring 10 is The stopper plate 9 is hooked onto a bent portion 9a at the lower end of a stopper plate 9 that is integrally fixed to the back surface of the lower plate 5, and is located below the back surface side of the portion where the hinge pin 6b is disposed. The coil spring 10 has a function of offsetting the moment when the door 7 opens due to its own weight. Further, when the door 7 is in the closed state as shown in FIG. 4, the spring force of the coil spring 10 hardly acts on the hinge member 6.

る。 In the door opening/closing device configured as described above, when the door 7 is opened in the direction of arrow A shown in FIG. 4, the coil spring 10 is rotated around the hinge pin 6b of the hinge member 6. The spring force acts in a direction to suppress the rotational force of the opening door 7. That is, the moment due to the weight of the door 7 is offset by the spring force of the coil spring 10. Therefore, even if the door 7 is rotated by its own weight in the direction of the arrow A in FIG. There is no collision, and it is almost the same as opening it while supporting it with your hand. This can prevent deformation of the hinge portion and others.

なお、この考案はかご操作盤の開戸に限定され

る効果がある。 As explained above, the operating panel opening/closing device according to this invention has the U-shaped portion 6a of the hinge member 6.
The opening end of one side is pivotally supported on the back surface of the lower edge of the opening of the operation panel main body 1 by a horizontal hinge pin 6b,
The other side of the U-shaped portion 6a that protrudes outward from the opening end is fixed to the back surface of the lower edge of the door 7, so that one side of the U-shaped portion 6a hits the lower side of the opening of the main body 1. The upper end of the coil spring 10 is connected to the opposite side of the open end of one side of the U-shaped portion 6a, and the main body 1 is held in a horizontal open position.
Since the lower end of the coil spring 10 is connected to the back side below the hinge pin 6b of 0, when the door 7 is opened from top to bottom with its own weight centered on the hinge pin 6b, the moment due to the weight of the door 7 is absorbed. This is offset by the spring force of the coil spring 10, so that the hinge member 6 and the like are not deformed.Therefore, there is no need to place a hand on the door to open it, which has the effect of making the door easier to handle.
