REMOTE CONTROL

OBJECT OF THE INVENTION

The object of this invention is a remote control which is used to control a power transmission device and a power transmission body.

STATE OF THE ART

A known power transmission device is shown in the publication FI 11263, figure 1 of the publication shows a known power transmission device with foot pedals 168 and 169, with which the cable 110 can be rotated in the desired direction, a power transmission element, which in the publication is a rotating cable with a non-rotating guard inside the guard. The desired tool is attached to the end of the cable (the power transmission element of the power transmission, i.e. the cable).

The disadvantage of the current technology is that the pedals of the power transmission device and the power transmission device are located in the power transmission device or in its immediate vicinity from the power transmission device and the pedals are used with the foot, due to which the user needs two hands to control the power transmission device and the other foot to control the rotation of the cable inside the power transmission device. Due to the above, the user has to stand on one leg during working hours, when the work is very heavy and occupational safety is also jeopardized, because the worker can, for example, stumble while working. Previous solutions for footrests are clumsy, heavy and very difficult to use in cramped spaces where work is often done. n PURPOSE OF THE INVENTION

N 25 — The purpose is that the remote control can be attached to the transmission body at the desired

to the point where the power transmission device and the power transmission body can be controlled close to the work

I detta with two hands.

OF

E n The above disadvantages can be eliminated and the above-mentioned goal is achieved with the invention

With a remote control according to S 30 — which is characterized by what is defined in the feature part of claim 1. Advantageous embodiments of the remote control are patent-

As the object of N requirements 2 — 10.

The most important advantages of the invention can be mentioned that the invented remote control improves work ergonomics by enabling the use of the so-called well-known trigger, which is easy to adopt, where the remote control can be used with one finger, which controls the rotation of the cable of the power transmission element, giving the user a more secure feeling of the power transmission - — to use the device. Faster operation and, above all, safer working, because the user can stand on both feet while working. The invented remote control is connected to the side of the power transmission device (non-rotationally coated cable) in use so that the cable and the remote control can be held simultaneously. The remote control enables control during working hours (quick observation) of the power transmission device with the on/off function, the on and off function is done with the use of one finger, in which case the user has a very sensitive feel for the rotation of the cable, he immediately notices, for example, if the tool at the end of the cable clings to the object to be worked on, such as the inside of a sewer pipe, in which case the user immediately interrupts the rotation of the cable by releasing the button on the remote control that controls the rotation of the cable, the overload - expansion button or other known means of disconnecting/connecting the current. The remote control is connected to the power transmission device with a well-known spiral electric cable containing a spring, so the length of the electric cable is automatically adjusted to be longer and shorter as the user moves between the workstation and the power transmission device. The remote control uses a low voltage of 24 volts or 12 volts, which prevents the risk of electric shock, the low voltage can also be produced with a battery instead of a transformer, if the battery is used, the power supply is constantly secured even if there are power cuts. It is clear that the use of the invented remote control achieves a great saving in the control of power transmission devices and power transmission members, since the worker can control the power transmission device and power transmission device without the help of : legs.
