2. Description of the Related Art A control device for remotely controlling a construction machine, a crane, or a mobile workbench for working at a high place incorporates a plurality of sets of transmission / reception circuits inside a panel box (case). These are operated by a plurality of operation levers. An operator carries this panel box and operates it while visually recognizing the driven device from an appropriate position.

A plurality of operation levers of a portable control device are usually installed side by side on a panel box at regular intervals, and an operator operates them to move a driven device such as a construction machine in an intended direction. Or make them pick things up. As a conventional control device, a remote control device such as those described on pages 98 to 99 of "Radio Control Handbook (Radio Experiment Co., Ltd., published May 20, 1989)", 101 pages of the same publication. There are known remote control devices such as the ones described in pp. 138, as well as the ones operated by one hand such as the one described in page 160 of the same publication.

[0004]

Although various types of portable control devices are known as described above, all of them are provided with a plurality of operation levers, ON / OFF switches, and frequency switching switch buttons on the upper surface of the panel box. Etc. are the same in that they are arranged. All of them are also common in that they are arranged on a flat panel. However, when a large number of operation levers, operation buttons and the like are arranged in parallel on a flat panel, the operator sometimes operates the operation lever by mistake because he / she operates the driven device at a long distance while visually recognizing it. Further, when a large number of operating levers are carried for a long time while being carried, there is a problem in that the shoulders are overloaded or unreasonably applied, and the shoulders tend to be stiff or fatigued.

The present invention has been made in view of the above-mentioned problems, and when a driven device such as a construction machine is remotely controlled to move or drive, it is easy to operate and fatigue does not occur even if operated for a long time. It is an object of the present invention to provide a portable control device which is less in number and can avoid malfunctions.

[0006]

That is, in order to solve the above-mentioned problems, the present invention is directed to a portable control device in which a top surface of both end portions of a panel box on which a transmitting / receiving circuit is arranged is inclined forward. And an operation lever for changing the amount of electricity of the transmitting / receiving circuit are arranged on the upper surface of the central portion and the upper surface of the central portion. It is characterized in that a smooth concave curved surface is formed.

[0007]

The operation when the portable control device is used as the above means will be described with reference to the attached FIG. First, in this portable control device, since the outer operation lever-2a (2d) is attached by inclining forward, the position of the hand operated by the operator becomes close to a natural body, and the operation range causes an unreasonable force on the hand and arm. There will be no range. Further, since the mounting angles of the outer operation lever-2a (2d) and the inner operation lever-2b (2c) are different, the operator can surely select the operation lever intended, and there is a risk of erroneous operation. You can avoid it. Further, since the portable control device comes into close contact with the worker's abdomen or waist when carried, it is easy to hold and has good stability. Furthermore, by providing the handles 3 and 4 and the like, they can be easily carried during transportation, and if the handles 3 and 4 are attached by the belt 6 attached to the waist, the operation lever-2a and the like can be operated without receiving the interference of the belt 6. It will be possible. If metal fittings 6a, 6b are attached to the tip of the belt 6 and the metal fittings 6a, 6b are hung on the handles 3, 4 or 5, the belt 6 can be hung from the shoulder and carried, and can be easily put on and taken off, and fatigue can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete implementation committee of the present invention will be described below with reference to the drawings. 1 is a plan view of the portable control device of the present invention, FIG. 2 is a front view, and FIG. 3 is a sectional view taken along the line AA of FIG. FIG. 4 is an overall perspective view of the portable control device of the present invention. This portable control device has four operation levers-2a, 2b, 2 in a panel box (case) 1.
Although c and 2d are installed (the number is four in the embodiment but not limited to this number), the upper surfaces of both ends of the panel box 1 are formed with inclined surfaces 1a and 1b that are inclined forward.
The operation levers-2a and 2d are installed on the inclined surfaces 1a and 1b, respectively. Although not shown, a transmission / reception circuit is arranged in the panel box 1, and the operation levers-2a, 2b, etc. are used for driving the rotary shaft of the potentiometer to change the electric quantity of the circuit. .

A smooth concave curved surface 1c is formed on the end surface of the panel box 1 on the operator side, and the front surface of the abdomen or waist of the operator is properly brought into contact therewith. If the concave curved surface 1c is formed on the operator-side end surface in this way, the operator can easily hold it without shaking because it fits the curve of the body when carried by the operator. The radius R of the concave curved surface 1c is set so as to approximately match the abdomen or waist of the worker.

Next, the two operation levers-2b and 2c are arranged on the central upper surface 1d of the panel box 1. As shown in FIG. 3, if the outer operation levers-2a and 2d and the inner operation levers-2b and 2c are arranged at different standing angles, the outer operation lever-2a and the inner operation lever-2b (or Since it is possible to clearly distinguish between the operation lever-2d and the operation lever-2c), it is possible to avoid a malfunction during operation. Also, the outer operation lever-2a and the inner operation lever-2
Even if b (the same applies to the operation lever-2d and the operation lever-2c) are mounted close to each other, there is no interference (such as hitting the back of the hand) at the time of operation, and it is possible to prevent malfunction also in this respect. Further, since the panels can be mounted close to each other, the overall size of the panel box (case) 1 can be reduced.

The upper surface 1d of the panel box 1 on which the operation levers 2b and 2c are arranged may not be a horizontal surface but may be angled so as to be slightly inclined outward or inward (worker side).

The embodiment of the portable control device of the present invention is as described above. Next, its operation will be described with reference to FIG. 5 showing a state in which the operator carries it. First, in this portable control device, since the outer operation lever-2a (2d) is attached by inclining forward, the position of the hand operated by the operator becomes close to a natural body, and the operation range causes an unreasonable force on the hand and arm. There will be no range. Further, since the mounting angles of the outer operation lever-2a (2d) and the inner operation lever-2b (2c) are different, the operator can surely select the operation lever intended, and there is a risk of erroneous operation. You can avoid it. Further, since the portable control device comes into close contact with the worker's abdomen or waist when carried, it is easy to hold and has good stability. Further, by providing the handles 3, 4, and 5, it is easy to carry during transportation, and metal fittings 6a, 6b are attached to the tip ends of the belt 6 on which the handles 3, 4, and 5 are hung from the shoulders, and these are attached to the handles 3, 4 or 5. If you wear it, you can hang it over your shoulder, carry it on and off easily, and reduce fatigue. Further, if the belt attached to the waist is attached to the handle 5, the operation lever-2a and the like can be operated without receiving the interference of the belt 6 hung from the shoulder.
