Definitions

  • the invention relates to a rotary handle for manually actuating a power drive for a device.
  • the main purpose of the twist grip is to enable the device to be operated if the power drive fails for any reason, e.g. B. because the power supply to operate an electric motor has failed or compressed air or another medium is temporarily not available.
  • a twist grip of the type mentioned is z. B. provided in a motor drive for electrical switching devices according to US-PS 31 71 920. However, it is only intended to be used for manual actuation in order to bring a linearly displaceable carriage into a specific position in which it can be brought into engagement with the actuating handle of an electrical switching device. If the electrical switching device is to be switched on and off when the power supply to the electric motor of the power drive fails, the entire power drive is folded down from the electric switching device in order to make its actuating handle accessible.
  • the invention has for its object to provide a handle of the type mentioned, which allows the manual operation of the device even with a coupled power drive.
  • the rotary handle in the case of a cylindrical disk-shaped basic shape, is offset on both sides of an ideal diameter line to form an approximately parallel gripping surface and one to the upper edge has increasing slope.
  • the grip surfaces arranged according to the invention allow the introduction of a torque with thumb and forefinger without the risk of slipping.
  • the subsequent bevels reject the fingers and in any case prevent them from being carried along if the power drive z. B. is surprisingly set in motion when the auxiliary energy returns or with remote control. The rotary handle can therefore be in constant engagement with the power drive.
  • An advantageous field of application for rotary handles according to the invention is motor drives for electrical switching devices.
  • the invention is therefore explained in more detail below with reference to the embodiment shown in the figures, which is a motor drive for low-voltage circuit breakers.
  • Fig. 1 shows a motor drive in a side view.
  • FIG. 2 shows a perspective view of a rotary handle, a detail of which is shown in FIG. 3.
  • a low-voltage circuit breaker 1 of the so-called compact design is shown in broken lines in its outline.
  • the circuit breaker 1 has an insulating housing 2, in which a rotary bearing 3 Rocker arm 4 is pivotally arranged.
  • the rocker arm 4 is connected in a manner not shown to a switching mechanism which allows movable and fixed contacts to be brought into contact with one another and to be separated again in a known manner.
  • the circuit breaker 1 contains devices for automatic shutdown in the event of overload and short circuit.
  • the circuit breaker 1 can be designed such as this.
  • B. is described in DE-PS 28 11 441 or DE-PS 28 17 667.
  • An actuating handle 5 is placed on the rocker arm 4 and protrudes from a central elevation 6 on the front side of the circuit breaker 1.
  • This actuating handle interacts with a motor drive, designated as a whole as 10, which is also fastened by means of screws 11 on the front side of the circuit breaker 1.
  • the main components of the motor drive 10 include a support plate 12 which is fastened to the housing 2 by means of bends or attached angle pieces and the screws 11 already mentioned.
  • a slide 14 is guided in the direction of the double arrow 15 between the pressed-out tabs 13.
  • a window-like opening 16 of the slide 14 overlaps the end of the actuating handle 5 and a cylindrical body 17 which is attached to it. This is secured by a guide track 20 against radial escape.
  • a motor gear unit 21 is further fastened on the support plate 12 and consists of a motor 22 with an axis lying parallel to the support plate 12 and a reduction gear 23 with an axis of rotation perpendicular to the support plate 12.
  • the output shaft 24 of the transmission 23 carries a crank arm 25 with a crank pin 26. This engages between the legs 27 one Leaf spring 30, which extends parallel to the plane of the slide 14 and transversely to the direction of movement (double arrow 15).
  • the leaf spring 30 is used for elastic force transmission from the motor gear unit 21 to the slide 14, such that a tolerance compensation is brought about in the end positions.
  • Two limit switches 31 and 32 which are also fastened to the support plate 12 and whose actuating levers 33 and 34 cooperate with an extension 35 of the slide 14, offset by a step 39, ensure that the motor switch 22 is stopped when the circuit breaker 1 is switched on and off. All mentioned components of the motor drive are covered on the outside by a cap 36 which is provided with an opening for the passage of a rotary handle 37. This is rotatably attached to a shaft end of the output shaft 24 opposite the crank arm 25 and secured against removal by a collar 38. The rotary handle 37 is thus constantly in engagement with the reduction gear 23 and is rotated when the circuit breaker 1 is switched on and off by means of the motor drive 10. The peripheral speed is relatively low, because the output shaft 24 is the most strongly reduced shaft of the motor gear unit 21 and an angle of rotation of only about 180 ° is traveled to switch the protective switch 1 on and off.
  • the rotary handle 37 has a central web 40 in the case of an approximately cylindrical disk-shaped form, which is arranged symmetrically to an ideal diameter line.
  • the rotary handle 37 has gripping surfaces 41 and 42 as well as opposing, continuous bevels 43 and 44.
  • the diameter of the rotating handle 37 and thus the length of the gripping surfaces and Slant is chosen approximately according to the lengths of the human thumb and index finger when the index finger is bent.
  • the gripping surfaces 41 and 42 do not offer a sufficient possibility of attack due to their decreasing height. If the motor drive 10 is now surprisingly put into operation when an operator actuates the rotary handle in the manner indicated, the fingers are rejected by the bevels 43 and 44 without any risk of injury.
  • the shape of the rotary handle contributes, but also the fact that the rotary handle is connected to the most strongly reduced shaft, namely the output shaft 24 of the transmission 23, and therefore only achieves a relatively low peripheral speed.
  • the described rotary handle can be used not only for motor drives in accordance with the exemplary embodiment described, but also for power drives that work with compressed air or other media.
  • the power drive can be used with devices of any type in which the task is to provide the option of manual operation in addition to the operation by the power drive.
  • FIG. 3 shows the rotary handle 37 partially from below, ie from its side facing a stub shaft 45 of the output shaft 24.
  • the rotary handle 37 has an opening 46 which corresponds to the shaft end 45 which is flattened on both sides.
  • projections or elevations 50 are provided which are integral with the material of the rotary handle. These elevations narrow the profile of the opening 46 in such a way that the rotary handle is displaced or deformation of the elevations on the stub shaft 45 can be plugged and the twist grip is thereby secured against removal or falling. This results in a position securing independent of the collar 38 of the rotary handle 37.
