ハンドルを提供するという課題にもとづいている。This rotary handle can be used to operate the switch when the power drive has stopped working for some reason, such as when the drive power of the electric motor is cut off or compressed air or other media is temporarily unavailable. This is what makes it possible. Rotary handles of this type are disclosed, for example, in US Pat. No. 3,171.
92 is used in electric actuators for electrical switches. However, in this case the rotary handle is used only for manual operation to move the linearly movable carriage into a defined position where it engages the operating handle of the electrical switch. It is something that will be done. With this configuration, when attempting to turn on or off the electric switch when the electric motor of the power drive is turned off, move the entire dynamic drive away from the electric switch and operate the operating handle. do. 5. The invention is based on the problem of providing a rotary handle that allows manual operation of the switch even when the power drive is connected.

ドルの製作上及び外観上でも良好である。According to the invention, the rotary handle has a basic shape in the form of a thick-walled disk, and is provided with two gripping surfaces arranged substantially parallel to the axis of rotation of the disk on both sides of one ideal diameter line. The above-mentioned problem is solved by having the grooves cut in rows and each groove having an inclined surface rising up to the upper surface of the disk. In contrast to conventional types of rotary handles, for example knurled around the periphery, in a handle constructed according to the invention the gripping surfaces can transfer the rotational moments of the thumb and forefinger without the risk of slipping. Furthermore, an important characteristic of this rotary handle is that even if the power drive suddenly starts to move during manual operation, for example by restoring the drive energy source or by remote control, the slope deflects the fingers so that they are never caught. The rotary handle is therefore always available for engagement with the power drive. The fact that there is a strip-shaped surface extending with the ideal diameter line as the center line and two sloped surfaces running in opposite directions on both sides of the strip-shaped surface means that it is difficult to rotate as well as in handling. The handle is also good in terms of manufacturing and appearance.

隆起６から外へ突出ている。The switch 1 has an insulating case 2, in which a tumbler lever 4 is arranged so as to be able to swing around a rotary bearing 3. Although details are not shown, the tumbler lever 4 is coupled to an opening/closing mechanism that can bring the movable contact and the fixed contact into contact and disconnect in a known manner. Furthermore, the switch 1 is provided with a device for automatic disconnection 4 in the event of an overload or short circuit. The switch 1 is, for example, according to West German patent 2811441 or 28

The bent portion 18 surrounds the end portion of the cylindrical body 17 and the cylindrical body 17 inserted therein. The cylindrical body is held down 7 by guide rails 20 to prevent it from coming off in the radial direction. An electric speed reduction mechanism 21 is further fixed to the soil of the support plate 12, and the electric motor 2 has a shaft parallel to the support plate 12.

されている。The double-end switch acts to stop the electric motor 22 when the switch 1 is turned on and off. All the above-mentioned components of the electric actuator are covered from the outside by a cover 36, which is provided with an opening through which a rotary handle 37 passes. The rotating handle is inserted into the other shaft end of the output shaft 24 protruding on the side opposite to the crank arm 25, and is held by a flange 38 so as not to come off. Therefore, the rotary handle 37 is always engaged with the speed reduction mechanism 23 and rotates together with the electric actuator when the switch is closed and closed. Output f1
! 24 is the final stage reduction shaft of the electric reduction gear mechanism 21, and since it rotates only about 180 rotation angles for closing and closing the switch 1, the circumferential speed of the rotating handle at that time is relatively low. . The shape of the rotary handle 37 is shown in FIG.

軸２４の軸端４５に向いた面から見た所を示す。As you can see from the figure, the basic shape is a thick disk. The rotary handle has a central strip 40 arranged with one ideal diameter line as the centerline. The rotary handle 37 has gripping surfaces 41 and 42 and sloped surfaces 43 and 44 running in opposite directions on either side of the band surface. The diameter of the rotary handle 37 and thus the length of the gripping surface and the ramp are chosen to accommodate a person's thumb and folded index finger. Place your thumb on the inclined surface 43,
When the bent index finger is placed on the inclined surface 44, a rotational moment is applied to the rotating handle 37 only in the clockwise direction.
For the counterclockwise direction, the gripping surfaces 41 and 42 are decreasing in height and cannot grip sufficiently. Even if the electric operating device 10 suddenly starts moving while the operator is operating the rotary handle in the instructed manner, the fingers will not be able to keep up with the inclined surface 43.
and 44 without risk of injury.
In this case, not only the shape of the rotary handle but also the fact that the rotary handle is connected to the final stage reduction shaft, that is, the output shaft 24 of the reduction mechanism 23, and therefore the circumferential speed is relatively low, contributes to safety. The rotary handle described above can be used not only for electric actuators according to the described embodiments, but also for power drives operating with compressed air or other media.
Furthermore, the power drive can be used for any type of switchgear for which there is a problem of enabling a manual emergency operation in addition to the actuation thereof. FIG. 3 shows the rotary handle 37 partially from below, ie from the side facing the shaft end 45 of the output shaft 24. FIG.

位置の確保がえられる。As can be seen, the rotating handle 37 has a hole 46 that accommodates a shaft end 45 that is ground flat on both sides. hole 46
The cylindrical body 47 is provided with a protrusion or bulge 50. This ridge narrows the cross-section of the hole 46, so that the rotating handle displaces or deforms the ridge while pushing the shank end 46 out of the way.
5, thereby protecting the rotary handle from dislodging or falling. This ensures a position of the rotating handle 37 independent of the flange 38.
