Definitions

  • the invention relates to a rotary handle of cylindrical disk-shaped basic form for manual operation of a device with a web arranged symmetrically to an ideal diameter line and on both sides of the same approximately parallel to the cylinder axis arranged gripping surfaces, whereby on both sides of the web a slope is arranged with mutually opposite inclination and these slopes under enlargement or reduce the height of the grip surfaces along the diameter line from the height of the web or increase to the height of the web.
  • twist grip is known from GB PS 869 125.
  • the twist grip is dimensioned so that it is actuated with the ends of the thumb and forefinger. This limits the forces to be exerted to relatively low values.
  • the invention has for its object to design the twist grip so that it is also suitable for exerting greater forces such as z. B. occur in the manual operation of a power drive for electrical switching devices. This process is important if the power drive does not work in the intended manner, in particular if the power supply to an electric motor fails or if compressed air or another medium is temporarily unavailable. An injury to the hand should be avoided if the power drive starts again during manual operation.
  • this object is achieved in that the diameter of the rotary handle and the length of the bevels of the human thumb and the index finger are adjusted when the position is bent, that the rotary handle is part of a motor drive for electrical switching devices and constantly engages with a shaft of the motor drive stands and that the inclinations of the grip surfaces depending on the direction of rotation of the motor drive are chosen so that the fingers slide off the rotary handle when starting the motor drive.
  • This not only enables the desired convenient exercise of the driving forces, but also ensures safe handling, because the twist grip rejects the fingers and prevents them from being carried if, for example, during handling.
  • B. is surprisingly set in motion by the return of the auxiliary energy or as a result of remote activation of the power drive.
  • Rotary handles are already known which are constantly in engagement with a motor drive (US Pat. No. 3,171,920).
  • the rotary handle In order to prevent the operator's hand from being carried along, the rotary handle is designed as an essentially smooth cylindrical body, which, however, makes it difficult to introduce a strong torque with easy handling.
  • the rotary handle has an opening for plugging onto the end of a shaft of a transmission and at least one elevation which narrows the profile of the opening.
  • Figure 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 FIG. 1.
  • the circuit breaker 1 has an insulating material housing 2, in which a rocker arm 4 is arranged pivotably about a pivot bearing 3.
  • 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 15 overlaps the end of the actuating handle 5 and a cylindrical body 17 which is attached to it. This is secured against radial escape by a guide track 20.
  • 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 of a leaf spring 30 which extends parallel to the plane of the slide 14 and transverse to its direction of movement (double) (pfeii15).
  • the leaf spring 30 is used for elastic power transmission from the motor gear unit 21 to the slide 14, such that in the end tolerance compensation is achieved.
  • 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 fitted onto 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 twist grip 37 has gripping surfaces 41 and 42 as well as opposing, continuous bevels 43 and 44.
  • the diameter of the twist grip 37 and thus the length of the gripping surfaces and bevels is approximately corresponding to the lengths of the human thumb and index finger when the position is bent Index finger selected.
  • 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, i. H. from its side facing a shaft end 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 can be plugged onto the stub shaft 45 while displacing or deforming the raised portions, and the rotary handle is thereby secured against removal or falling off. This results in a position securing independent of the collar 38 of the rotary handle 37.
