Definitions

  • the invention relates to a reset device on an arbitrarily manually switchable rotary switch for resetting the same when the mains voltage drops below a predetermined limit value, in which an electromagnet can be connected to the mains and is provided with an armature and penetrated by a switch or drive shaft , on the armature of which at least one locking plunger which is displaceable in the longitudinal direction of the switch or drive shaft is resiliently supported and which can be displaced transversely to the switch or drive shaft on at least one toothed section which is in engagement with a toothed section of the switch or drive shaft, acted upon by a return spring and elevations and / or depressions provided and acts in a switch position different from its starting position and the armature blocked the return device and when the net dropped below a certain limit releases tension.
  • Such a reset device was known from AT-PS 367 566. In this a continuous switch or drive shaft is provided, with which the retractors mesh and the locking plungers act directly on them. This reset device has proven itself very well in applications in which no tripping is required.
  • the aim of the invention is to propose a reset device of the type mentioned in the opening paragraph in which a free release is possible and which is characterized by a simple structure.
  • the switch or drive shaft has a further, loosely rotatable section with respect to its section which meshes with the retractor (s) and which is rotatably connected to the area which can be driven by hand, and which is prestressed against the rest position of the switch, with at least a driver is connected to the drive, on which a transmission element, which is provided with recesses and / or depressions and is movable essentially in the direction of the longitudinal axis of the switch or drive shaft, is held, the Recesses and and or recesses with the recesses of the associated plunger and the retractor can be brought into engagement, wherein the engagement of the S perr- plunger with the transfer member, and this with the retractor only when exposed to a force acting in the direction of tightening of the anchor force for the transfer of the Sufficient deflection of the switch from its rest position is sufficient.
  • the solution according to the invention manages with relatively few individual parts and it is achieved through the use of toothed racks and pinions that the power transmission takes place over relatively large areas, whereby the use of plastic for the manufacture of the individual parts becomes problem-free.
  • the transmission member is pivotally held on a pin of the driver and extends essentially transversely to the longitudinal axis of the switch or drive shaft, which eliminates the need for complex guides for the transmission member.
  • the pin of the driver holding the transmission member has a shoulder extending in the longitudinal direction along its jacket, and the hole of the transmission member receiving the pin has a groove corresponding to the shoulder, the width of which exceeds the width of the shoulder a limitation of the path of movement of the transmission member is achieved, so that even with unfavorable installation positions of the switch there is no risk of ver clamping of the transmission link is given.
  • the mutually facing projections and / or depressions of the return element and the transmission member engage in a hook-like manner, the surfaces of the projections and / or recesses lying against one another during a transmission of force for carrying the return element with respect to the holder of the transmission member are inclined such that a force component acting in the sense of releasing the engagement or a corresponding torque occurs.
  • a pivotable transmission link e.g. can be achieved in such a way that the inclination of the mutually contacting surfaces of the hook-like projections is selected such that a perpendicular to this surface which passes through the center of the overlapping surface of these two surfaces has a corresponding normal distance from the axis of rotation of the transmission member, so that in the case of in the direction the switch or drive shaft displaceable transmission members the contacting surfaces of the hook-like projections run inclined against the guides of the transmission members.
  • the cooperating with the locking plunger projection or recess of the transmission member is arranged in the region of one end, and the side facing the locking plunger of the transmission member when the switch is deflected from its rest position against the end lying behind during the deflection movement too obliquely against the direction of attraction of the armature runs inclined.
  • FIG. 1 shows a section through a switch with a reset device according to the invention
  • FIG. 2 shows an exploded view of the reset device of the switch according to FIG. 1
  • Fig. 3 to 8 plan views of the free release mechanism with the housing broken away in different switching states and different excitation of the electromagnet.
  • the drive or switch shaft 1 is formed by individual shaft sections 1'-1 vi , the sections 1 v and 1 vi controlling the two planes of the switch 2 or the contacts arranged therein and the sections 1 "'and 1 iv are provided with an additional external toothing 3, but have no intermeshing internal and external toothing and can be rotated relative to one another.
  • the shaft sections 1 ', 1 "running in the resetting device 4 and the shaft sections running in the switch 2 are 1 v and 1 V ) on the other hand with each other and with the adjacent shaft sections 1 "'and 1 iv rotatably by means of meshing inside and outside gears connected.
  • the resetting device 4 essentially consists of the two housing halves 5 and 6 in which the shaft sections 1 "to 1 lv are mounted.
  • a pot magnet 7 together with its armature 8 is inserted into the housing halves 5, 6 or guided in corresponding grooves in the housing halves 5, wherein the core 9 of the magnet is hollow and is penetrated by the shaft sections 1 "and 1"'.
  • the coil 10 of the magnet 7 is preferably supplied from the mains via a rectifier bridge.
  • the armature 8 has projections 12 which engage in recesses 14 of locking plungers 13 which are guided in grooves in the housing half 5 and are displaceable in the direction of the longitudinal axis of the drive or switch shaft 1.
  • the locking plungers 13 are supported on the armature 8 by means of pressure springs 11 resting on the projections 12, different preloads of the pressure springs 11 being obtained when the armature 8 is tightened (as shown in FIG. 1) or has fallen off.
  • an indentation 15 is provided which ensures an air gap which is sufficient to allow the armature 8 to fall off.
  • very weak springs 30 (FIG. 2) are provided, which are supported in the housing part 5 and press the armature 8 lightly against the core 9 of the pot magnet, but this causes the armature to fall off among them onto one another a switch 2 located in the rest position of the gap position acting forces is not hindered if the mains voltage drops too far.
  • the locking plungers 13 are pressed by the compression springs 11 against a respective transmission member 34.
  • This transmission member 34 is on a driver 35 or on its pin 36 pivotally and therefore movable in its free end region essentially in the direction of the switch or drive shaft 1.
  • This driver is designed as a rack and meshes with the external toothing 3 of the shaft portion 1 "'which, as already mentioned, rotatable but relative to the shaft portion 1 1v with the shaft portion 1" is connected in a rotationally fixed and also with the not-shown handle.
  • the pin 36 is provided with a spring-like projection 37 extending in its longitudinal direction, the width of which is less than a groove 39 machined into the bore 38 of the transmission member 34.
  • the transmission member 34 has on its side facing the locking plunger 13 an inclination toward the free end toward the tightening direction 43 of the armature 8.
  • a recess 40 is arranged, the wall 41 of which has an inclination corresponding to the flank 17 of the nose 18.
  • the springs 11 are Inclination of the surfaces 17 and 41 adjusted such that the locking plunger 13 can be pressed against the force of the springs 11 despite the tightened armature 8 by a corresponding rotation of the switch or drive shaft 1, whereby the blocking of the driver 35 and the return device 16 is released is and the latter turn back the switch 2 with relaxation of the springs 21 and thereby take the transmission members 34 and thus also the driver 35 (Fig. 7).
  • the locking plunger 13 blocks the return element 16 acted upon by the spring 21 via the transmission member 34, which is hooked to the return element 16.
