Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a multi-directional control switch used in a transmitter for a remote control device of a work gondola, a work robot, etc.

[Conventional technology] Civil engineering construction work, manufacturing of large machinery in factories,
When working inside a ship, etc., where there is no scaffolding or at high places where people cannot work under normal conditions, a work machine such as a gondola or a trolley is mounted on a boarding device, and the worker himself operates the boarding device. Work can be done by operating the equipment's switches, or by having another person remotely control the work in the control room.

Conventionally, the switch mechanism of a transmitter that operates a remote control device is a transmitter that has a switch that tilts in multiple directions using the intermediate point of the lever stick as a fulcrum and moves the boarding device in the X direction and Y direction. Many have two switch mechanisms: one that operates in the vertical direction and one that operates in the horizontal direction.

[The problem that the idea aims to solve]

The input method for operating the above boarding device is as follows.
In a transmitter that incorporates a switch that operates in the X direction and the Y direction into one mechanism, the operation of the boarding device at the time of startup tends to be unstable and not smooth. That is, the torque that rotates the shaft of the potentiometer, etc. of the transmitter's switch mechanism is too large, and the acceleration of the boarding device is large, and the speed suddenly increases from zero to a large speed, which tends to cause a sense of anxiety to the operator on board.

On the other hand, with the two switch mechanism transmitters, there is a push button type when reversing, but this also causes a discontinuous step-by-step acceleration motion that tends to cause a sense of anxiety to the worker. In any case, there is a problem in that, in the conventional operating method using the switch mechanism of the transmitter, if the boarding device operates suddenly, it is likely to cause the pilot to malfunction, which is dangerous.

This invention was made in view of the above-mentioned problems, and its purpose is to smoothly accelerate the work boarding device steplessly when working by boarding the work boarding device at high places or in places without scaffolding. To provide a transmitter switch mechanism which smoothly adjusts the speed according to one's will, moves the boarding device in the X direction and the Y direction, and provides an excellent sense of safety when operating the boarding device.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention
The multi-directional control switch consists of a lever stick that can be tilted in multiple directions using a sphere formed in the middle of the bar as a fulcrum, and a lever stick that bends the three adjacent planes so that they are at right angles to each other and rotates around the axis of rotation. A panel is provided with a potentiometer mounted so that the potentiometers are perpendicular to each other; A shaft is fixed to the rotating shaft of the panel, and the other upper end is rotatably pivoted to the supporting portion of the panel, and two fulcrums are formed on both sides of the shaft, and the panel is mounted so as to be arranged at right angles to each other. a slider having a substantially L-shape, and a return lever having a substantially L-shape, which is rotatably pivoted to the panel near a corner with a bolt, and one end of the L-shape has one end attached to the end of the panel; a return lever that locks the other end of the locked coil spring and is rotated at two fulcrums of the slider; It is characterized by being inserted.

[Effect]

If the multi-directional control switch according to the present invention is configured as described above, it will be explained using the reference numerals in the attached embodiment drawings. For example, when remotely controlling a work boarding device, when the lever stick 2 is rotated, the slider 7 ( (same for slider 8) fulcrums 73 and 74
Either one of them serves as a fulcrum, and the shaft 9 of the potentiometer 17 rotates. At the same time, a biasing force acts on the coil panel 12 and the potentiometer 17
When the shaft 9 of the lever is slightly and smoothly rotated to either side and the knob 1 of the lever stick 2 is released, it smoothly returns to the neutral position. Therefore, the boarding device with an excess number of workers begins to move subtly and smoothly at the time of startup, and then comes to a slow stop.

〔Example〕

Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

Fig. 1 is an assembled perspective view of the multi-directional control switch according to this invention seen from below, Fig. 2 is a vertical sectional view seen from the left side of Fig. 1, and Fig. 3 is a rear view of Fig. 1. FIG. In these figures, 2
is a lever stick with a knob 1 attached to the top for manual operation. The lever stick 2 is covered with a boot 3 to prevent dust from entering.

Reference numeral 4 denotes a panel in which three adjacent planes are bent at right angles to each other, and together with a locking portion 51 of a conical flange 5, an operation box panel P is attached.
Fix it with hexagon socket head bolts 15 and 16. 6
is a spherical bearing which rotatably fits and supports a sphere 21 formed at the intermediate portion of the lever stick 2 and is fitted into the flange 5. Further, potentiometers 17 and 18 are attached to the panel 4 so that their rotation axes are perpendicular to each other.

Reference numerals 7 and 8 denote sliders which are formed in an elongated U-shape as a whole, and further have elongated holes 71 and 81 bored in the lower part. These sliders 7 and 8 are arranged at right angles to each other, and taking the slider 7 as an example, as shown in FIG. 17, and a shaft 72 is formed at the other upper end facing outward, and the shaft 72 is rotatably pivoted to a support portion 41 formed on the panel 4 by burring. It is supported.

The slider 8 also has a similar structure to the slider 7, and one upper end portion is fixed to the rotating shaft 9 of the potentiometer 18. The height of the slider 7 is made higher than that of the slider 8 to prevent collision during rotation. The tip of the lever stick 2 is connected to the elongated hole 7 of the sliders 7 and 8 which are arranged in an intersecting manner.
1,81 is inserted so as to penetrate through it.

Next, reference numerals 10 and 11 indicate return levers having a substantially L shape, and are rotatably attached to the panel 4 near the corners with bolts. Taking the return lever 10 as an example, the other end of a coil spring 12, which has one end locked to the end of the panel, is locked to one tip. The same applies to the return lever 11.

Next, as described above, the slider 7 has one upper end fixed to the rotating shaft 9 of the potentiometer 17, and the other upper end shaft 72 rotatably attached to the support part 41 formed on the panel 4. Although it is centrally supported, the third
As shown in the figure, there are two fulcrums 7 next to the shaft 72.
3.74 is formed.

If the multi-directional control switch according to this invention is configured as described above, when the lever stick 2 is rotated, for example, when remotely controlling a work boarding device, the fulcrum 73 of the slider 7 (same as the slider 8),
74 serves as a fulcrum, and the shaft 9 of the potentiometer 17 rotates. At this time, a biasing force is simultaneously applied to the coil spring 12 to subtly and smoothly rotate the shaft 9 of the potentiometer 17 in either direction, and when the knob 1 of the lever stick 2 is released, it smoothly returns to the neutral position. Therefore, the boarding device with an excess number of workers begins to move subtly and smoothly at the time of startup, and then comes to a slow stop. In addition, since the lever stick 2 can be tilted in multiple directions simultaneously using the sphere 21 as a fulcrum, the potentiometer 17
It goes without saying that by operating the and 18 at the same time, the boarding device can also be moved in the X direction and the Y direction at the same time.

[Effect of idea]

Since the multi-directional control switch according to this invention has the configuration described in detail above, if it is used as a switch for a transmitter of a remote control device, when the lever stay is tilted, the force applied to the slider via the return lever can be reduced. is saved, so multiple potentiometers directly connected to the slider can be smoothly and slowly varied. With such smooth operation, the operator on the boarding device can independently move the boarding device in the X direction,
It can be moved freely in the Y direction, and gradual and stepless speed conversion and adjustment, which is said to give the human body the most sense of security, is possible, making it possible to feel dangerous even when moving when working at heights. That will no longer be the case. Furthermore, it is compact as a whole, easy to assemble, easy to replace parts and maintain, and is extremely effective in terms of work safety management.
