Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing mechanism used in, for example, an opening/closing valve for a gas staple or various other similar devices.

For example, in gas staple equipment, the mechanism for opening and closing the on-off valve of the burner is one end of the rotating shaft directly connected to the operation knob provided on the front panel of the case body, and the other end connected to the on-off valve body. The gas supply was turned on and off by rotating the control knob.

. 1'The opening/closing mechanism described above is not very aesthetically pleasing, as its operation knob remains exposed on the fixed front panel plate, and it is also difficult to use when the device is not in use. There was also a danger that the exposed operation knob could get in the way or be accidentally touched by children.

The present invention was devised in view of the above circumstances, and allows a panel equipped with an operation knob to be inverted and stored inside the device when not in use, and allows the controlled device to be operated normally. The purpose of the present invention is to provide a mechanism for controlling and operating various types of equipment.

For this reason, the structure of the present invention consists of a triangular cylinder having a hollow inside, one of the three flat surfaces on the outer surface of the triangular cylinder is an open third flat surface, and the other two are open. The surface is the first
and a knob holder serving as a second flat portion;
A knob shaft is provided protruding from the flat side of the knob shaft, the inner end of which is integrated with the gear disposed in the cavity, and the knob shaft is meshed with the gear in the cavity provided on the second flat side. a universal shaft integrated with the gear; a first transmission shaft connected to the universal shaft via a universal joint;
A second transmission shaft is connected to the first transmission shaft so as to be expandable and retractable relative to the first transmission shaft, and a universal joint provided on the second transmission shaft for operating a controlled device has a substantially V-shaped cross-sectional shape. , has a panel plate whose inner surfaces on both sides are placed in close contact with the first and third flat surfaces of the knob holder, and an opening window, and the third plate is attached to the edge of the opening window. This control operation mechanism for various types of equipment includes a case body to which an end of a back plate of a panel plate that is brought into close contact with a flat surface side is pivotally attached.

Next, the above-mentioned operation will be described. Since the panel is pivotally attached to the edge of the case body, it rotates half a turn about the pivot point.

By this rotation, the operating section consisting of the holder attached to the panel, gears, knob shafts, etc. is housed within the case body.

When the operating section is housed in the case body, the back plate of the panel plate that is in close contact with the third flat part side of the knob holder closes the opening window of the case body.

In addition, as the position and direction (angle) of the operating section changes during the above-mentioned inversion and rotation of the panel board, the position and direction of the universal joint, transmission shaft, etc. connected to the operating section also change. Fluctuations are freely absorbed within the structure itself, so it operates without any problems.

The embodiment of the present invention shown in the drawings will be explained below.
In this example, when applied to gas staples,
This will be explained with an example.

Reference numeral 1 is the case body of the gas staple, and 2 is its front panel frame.

This front panel frame 2 is provided with an opening window, and an operating section 3 of the opening window is arranged to be reversible.

The operating section 3 is equipped with as many knob holders 4 as there are controlled devices, such as on-off valves.

The knob holder 4 has a flat part 8 having two flat parts 5 and 6 and one cavity 7. As shown in FIG.

A knob shaft 9 is provided to protrude from the above-mentioned flat part 5.

A gear 10 is rotatably attached to the inner end of the knob shaft 9.

This gear 10 is disposed within the cavity 7 described above.

The gear 10 meshes with the gear 11, and the gear 11
Also disposed within the cavity 7 described above.

A normal operation knob 12 is attached to the knob shaft 9.

The gear 11 is attached to a universal shaft 13 disposed on the plane portion 6 side.

Therefore, the rotational operating force of the knob 12 is transmitted to the gear 10.11 and to the universal shaft 13.

A roughly V-shaped panel 14 is attached to the flat parts 5 and 8 of the knob holder 4.

The panel 14d is located on the knob 12 side, and the back plate 14b is located on the flat part 8 side.

Therefore, when the knob 12 is exposed, the front panel 14a
is exposed, and conversely, when the knob 12 is retracted, the rear panel plate 14b is exposed and the opening window of the front panel frame 2 is closed.

The universal shaft 13 is connected to a first transmission shaft 16 via a universal joint 15.

The transmission shaft 16 is separated from the square shaft and is connected to the second transmission shaft 17 so as to be freely movable in and out.

The second transmission shaft 17 is formed into a hollow square shape, and a universal joint 18 is provided at its free end.

This universal joint 18 is connected to a controlled device, such as an on-off valve, which is not shown in the drawings.

Since the present invention has the configuration as explained above, now,
To explain the case where the operating section 3 is used while being exposed on the front side of the gas staple, the operating section 3 housed within the front panel frame 2 is reversed clockwise in FIG. 2.

Then, the knob 12 is projected outward from the front panel frame 2, and the front panel 14a closes the opening window 2a of the front panel frame 2 (see FIG. 1).

Therefore, the operating knob 12 is exposed to the outer surface of the front panel frame 2.

In this state, the operating knob 12 may be rotated as usual.

Rotation of the operating knob 12 causes the gear 10 to rotate together, and thus the gear 11 that meshes with it to rotate.

As the gear 11 rotates, the universal shaft 13 is rotated, and the first transmission shaft 16 is rotated through the universal joint 15.
is rotated.

This rotation of the first transmission shaft 16 causes the second transmission shaft 17 to rotate, and the controlled device is operated via the universal joint 18.

Furthermore, in order to store the operating knob 12 inside the device when the device is not in use, the operating knob 12 may be reversed in the opposite direction.

Then, the operation knob 12 and the front panel 14a are housed in the device, the back panel 14b is exposed, and the opening window 2a of the front panel frame 2 is closed.

Therefore, the operating knob 12 is not exposed to the outside, and the operating section becomes a completely flat surface.

In addition, when the operation section is reversed, its directionality is freely absorbed by the universal joint 15.18, and the length is such that the first transmission shaft 16 can freely move in and out of the second transmission shaft 17. Absorption is adjusted by

Since the present invention has the above-described configuration, when using the device, the operation knob can be projected outward from the front panel frame and exposed, and can be used in the same way as usual.

In addition, when the device is not in use, the operating knob can be inverted and stored inside the device, so there are no obstructive parts protruding from the front panel frame, resulting in a mechanism with a clean and very good appearance. can get.
