Description

[Detailed description of the invention] [Industrial application field] This invention is a multi-directional control switch used in a transmitter for a remote control device of a work gondola, a work robot, etc., and is particularly applicable to this switch. Regarding sliders.

[Conventional technology]

Civil engineering construction work, manufacturing of large machinery in factories,
When working in a place without scaffolding or at high places where people cannot work under normal conditions, such as when working inside a ship, the worker must board the boarding device of a work machine, such as a gondola or trolley, and use the operating device himself within the boarding device. You can work by operating a switch, or you can work in a control room while someone else remotely controls the work.

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. As shown in FIG. 5, it has a mechanism in which four switches M are attached to one panel, and a button C is pressed by a stick A via a lever B to operate the switch M in the vertical and horizontal directions.

[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. This is because the potentiometer shaft does not move smoothly during starting and stopping.

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 the operation method using the conventional transmitter switch mechanism is dangerous because if the boarding device operates suddenly, it is likely to cause the pilot to malfunction.

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. In addition, the multi-directional switch of the transmitter can smoothly adjust the speed according to one's will, move the boarding device in the X direction and Y direction, and has an excellent sense of safety when operating the boarding device. The goal is to provide a slider that can be used.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention
A lever stick that can be tilted in multiple directions using a spherical body formed in the middle of the bar as a fulcrum; a panel on which a potentiometer is attached; and a shaft formed on the panel, one upper end of which is fixed to the rotating shaft of the potentiometer, and the other upper end of which is rotatably supported on a supporting portion of the panel. a return lever which is approximately L-shaped and is rotatably pivoted to the panel near the corner with a bolt, and one end of the L-shape is rotatably attached to the panel near the corner; A multi-directional control used in a multi-directional control switch, comprising a return lever whose one end is fixed to the end of the panel, the other end of which is fixed to the other end of the coil spring, and the lever is rotated at two fulcrums of the slider. In the switch, the slider is formed into an elongated U-shape as a whole, and an elongated hole is bored in the lower part of the U-shape, and one upper end is fixed to the rotating shaft of the potentiometer, and the other upper end is fixed to the rotation shaft of the potentiometer. It is characterized in that it has a shaft rotatably supported on the support part of the panel and two fulcrums on both sides of the shaft, and are mounted so as to cross each other at right angles.

[Effect]

The operation of the above means will be explained using the symbols in the embodiment diagrams. When the lever stick 2 is rotated, the fulcrum 73 of the slider 7 (the same applies to 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. In particular, the driving force from the lever stick 2 is transmitted to the return levers 10, 11 via the two fulcrums 73, 74, and the biasing force from the coil springs 12, 13 is also transmitted to the potentiometers 17, 17 via these fulcrums. 18 axis is told to return to its original position, and the movement becomes smooth. Therefore, the boarding device on which the worker is riding 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 from below of a multi-directional control switch incorporating a slider according to this invention, and FIG. 2 is a vertical cross-sectional view seen from the left side of FIG. 1.
FIG. 3 is a side view of FIG. 1 as viewed from the rear direction. In these figures, 2 is a lever stick, and a knob 1 for manual operation is attached to the top. 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.

7 and 8 are sliders, and as shown in FIG. 4, the entire body is formed into an elongated U-shape, and furthermore, elongated holes 71 and 81 are 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 has the same structure as 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 to cross each other.
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 are 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 the work boarding device, the fulcrum 73 of the slider 7 (the same applies to the slider 8),
74 serves as a fulcrum, and the shaft 9 of the potentiometer 17 rotates. At the same time, a biasing force is applied to the coil spring 12 to delicately 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. In particular, the driving force from the lever stick 2 is transmitted to the return levers 10, 11 via the two fulcrums 73, 74, and the biasing force from the coil springs 12, 13 is also transmitted to the potentiometers 17, 17 via these fulcrums. 18 axis is told to return to its original position, and the movement becomes smooth. Therefore, the boarding device on which the worker is seated 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 potentiometers 17 and 18 can be operated simultaneously and the boarding device can also be
Needless to say, it is possible to simultaneously move in the direction and the Y direction.

[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 remote control device transmitter, when the lever stay is tilted about its spherical fulcrum, the return lever will be activated. Since the force applied to the slider is saved, multiple potentiometers directly connected to the slider can be smoothly and slowly varied.

Such smooth operation allows the operator on board the boarding device to freely and smoothly move the boarding device in the X and Y directions independently and according to his or her will, making it the safest for the human body. This enables gradual and stepless speed changes and adjustments that are said to give a sense of safety, and when working at heights, there is no longer any sense of danger when moving. Furthermore, by using this slider, the entire system can be made compact, and assembly, parts replacement, and maintenance are also easy, which is extremely effective in terms of work safety management.
