Definitions

  • the invention relates to a device for actuating an electrical circuit breaker or the like arranged remotely from it, as specified in the preamble of claim 1.
  • a device for actuating an electrical circuit breaker or the like which is arranged remotely from it and of the type specified in the preamble of claim 1 is already known.
  • the known device is attached with its support to the outside of a control cabinet door.
  • the carrier consists of a housing which is closed to the outside and in which the central disk connected to the handle is located.
  • the latch engages in the housing and, together with downstream locking members, prevents the control cabinet door from opening when the handle is in a position -ON- in which the assigned circuit breaker is switched on.
  • the lever is in two parts. One part is connected to the center disk and coupled to the second part by means of a split pin. The second part engages on the swivel member, which is arranged on the housing of the circuit breaker. This arrangement largely determines the spatial relationship between the device and its associated circuit breaker (US-A-3 229 0 56).
  • the object of the invention is to design the device specified in the preamble of address 1 for actuating a circuit breaker or the like which is arranged by it in such a way that the spatial relationship between it and the switch to be actuated by it is largely eliminated in a simple manner and at the same time an improved storage of the handle is achieved.
  • the object is achieved according to the invention by the training specified in the characterizing part of claim 1.
  • lo is a handling device.
  • Wall parts loa, lob of the handle device 10 are mounted upright on one side of a wall 14, which can be, for example, a door or a wall of a housing for electrical devices.
  • the wall parts loa, lob are provided with an unspecified support for attachment to the wall 1o.
  • a substructure 16 is fastened with screws 18, 20, which reach through the wall 14 and into the support of the wall parts loa, lob are screwed.
  • a two-armed pivot member 22 is articulated on the base 16 by means of a pin 23.
  • a lever 24 is articulated on an arm of the pivot member 22 by means of a pin 25.
  • the free end of the lever 24 is articulated to a center disk 48, described in more detail below.
  • the free end of the pivot member 22 is connected to a flexible push-pull member 26 which is surrounded by a likewise flexible guide sleeve 28 which, together with the push-push member 26, forms a device for transmitting longitudinal movements.
  • the guide sleeve 28 is fastened to the substructure 16 by means of a clamp 30.
  • a pin plate 31 is provided, which is articulated with a pin designated 32 on the free arm of the pivot member 22.
  • the handle device 1o includes a handle 33 shaped as a fork, which flanks the wall parts loa, lob with its prongs 33a, 33b, as can be seen particularly from FIG. 2.
  • the two prongs 33a, 33b merge into a grip part which carries a button 34 at its free end, which is explained in more detail below.
  • a slot is provided in at least one of the wall parts loa, 1ob, which in the example shown corresponds to a slot 36 in the prong 33a of the handle 33 for hanging a padlock when the handle 33 is in an end position which corresponds to the position -OFF- corresponds to a circuit breaker or the like to be actuated with the device, not shown.
  • a one-armed pawl 37 is articulated on at least one of the wall parts 10 a, 1 a of the handling device 10. At the free end of the pawl 37 there is an angled tab 38 which, in a manner not shown, can perform a locking function together with a door and / or another locking part.
  • a tongue 39 protrudes from the pawl 37 and is designed for the form-fitting engagement in a recess in the center disk 48 already mentioned.
  • the center disk 48 is flanked by two rotating bodies 44 (FIG. 2) and connected to these rotating bodies 44, which in turn are each connected to one of the prongs 33a or 33b of the handle 33.
  • a pin designated 4o forms a pivot axis for the pawl 37, which is clockwise under the pressure of a helical spring 41.
  • FIG. 2 in which the elements that correspond to those in FIG. 1 are provided with the same reference numerals as in FIG. 1.
  • a rivet is designated 43.
  • the rotating bodies 44 are connected to the prongs 33a, 33b of the handle 33.
  • the two rotary bodies 44 are respectively stepped in diameter and engage in a stepped bearing them accordingly opening of the associated wall part 1 a 0 or a 1o b.
  • the larger diameter of each rotating body 44 lies against the associated prongs 33a, 33b and carries an O-ring 45.
  • the smaller diameter of each rotating body 44 lies against the Center disc 48 on.
  • the described bearing arrangement of the rotating bodies 44 in the wall parts loa, lob allows the handle 33 to be pivoted slightly about the center of rotation of the rotating bodies 44.
  • the lever 24 is articulated on the center disk 48 by means of a pin 49.
  • the lever 24 is preferably forked at the end articulated on the center disk 48, as shown, so that its prongs enclose the center disk 48 between them.
  • FIGS. 1 and 2 are to be considered together. It can be seen that when the handle 33 is moved counterclockwise, the lever 24 pivots in the opposite direction. As a result of the movement of the lever 24, the pivot member 22 rotates clockwise around its pin 23. The tension-compression member 26 is pressed into the guide sleeve 28 such that it emerges from the guide sleeve 28 at the free end and exerts pressure on the circuit breaker or the like connected to it.
  • tension / compression member 26 instead of only one tension / compression member 26, several such elements can also be used in a manner not shown, together with their associated guide sleeves 28, in order to be able to switch a corresponding number of circuit breakers at the same time.
  • the pin 4 0 can in a manner not shown be provided with a slot in order to be able to move the pawl 37 from its locked position with a screwdriver or the like, so that the handle 33 can, if desired, be pivoted counterclockwise into an ON position.
  • the handle 33 has an opening in its prong 33a for the entry of the screwdriver which is aligned with the head of the pin 4o when the handle is in the position shown in FIG. 1.
  • the button 34 shown in FIG. 3 in an exploded view consists of two mutually identical parts 5 0 , 51. These two parts 5 0 , 51 engage between the handle parts of the handle 33 and, when assembled, result in the easy-to-grip button 34.
  • Each of the parts 50 , 51 has a straight section 52 and a conical section 53.
  • the straight portions extend at a distance parallel to each other, while the tapered portions are rotated 53 9 0 ° relative to the portions 52 and aligned with each other and are connected, for example by means of rivets to the handle 33rd
  • the selected shape of the parts 50 , 51 not only has the advantage that both parts can be produced in one and the same shape.
  • Another advantage is that 50 , 51 different colors can be selected for both parts, for example red and black.
  • the black part 5o can then, for example, indicate that the assigned switch is switched off, while the red part 51 in the corresponding position of the handle 33 indicates the ON position of the circuit breaker.
