Definitions

  • the invention relates to an actuator which is provided for switching a switching unit and has a mechanical display, wherein the mechanical display has a window and a display surface recognizable by the window.
  • Electromechanical command devices are widely used to operate and control machinery and equipment. These occur in various forms, for example as pushbuttons, toggle switches, key switches or emergency stop switches.
  • Control devices are mounted on control panels, control panels, control cabinet doors or enclosure covers. By manually operating the command devices electrical switching state changes and thus the desired control effects are generated.
  • Command devices are equipped as standard with a mechanical display to indicate prevailing switching states, the mechanical display optionally optionally or additionally equipped with an illuminable or illuminated unit.
  • Command devices are generally modular. This means that they consist of a pressure knob, a fastening part, such as a ring nut or a mounting bracket and at least one switching element or more
  • Switching elements which are designed as normally closed or normally closed contacts.
  • the actuator is usually guided from the front through a hole in the dash panel and mounted from behind by means of a fastening part.
  • the switching elements are mechanically fastened with screws, snap hooks or bolts on the actuator or on the fastening part.
  • an actuator is known from the prior art which is provided for switching a switching unit and has a mechanical display, wherein the mechanical display has a window and a display area which can be recognized by the window.
  • the display surface is one with an actuating part of the actuator attached spring bar connected and provided during an actuating movement of the actuating part together with at least a portion of the spring bar for partially rotating about an axis of rotation.
  • the axis of rotation is oriented essentially perpendicular to the actuating movement of the actuating part.
  • the object of the present invention is to provide an actuator with a mechanical signal display, which is structurally simple and allows reliable operation. This object is achieved by an actuator having the features of patent claim 1.
  • an actuator which is provided for switching a switching unit and has a mechanical display, wherein the mechanical display has a window and a recognizable by the window display area.
  • the invention is characterized in that the display surface is positioned on a guide web and the guide web is acted upon by a spring element with a spring force.
  • the aim is to move a display area behind a window of the command device, in particular of the actuator in such a way that at least one display surface is moved in or out of the window.
  • several rere display surfaces conceivable that at different
  • Switching states are each seen by the user through a window.
  • the mechanical display of the command device in particular the emergency stop switch, has one or more windows, one or more display surfaces and one or more guide webs attached to the actuating part of the actuator.
  • a guide bar is coupled to a display surface, connected or even connected in one piece.
  • the guide bar has on the one hand the task of holding the display surface and on the other hand, due to its elastic property and length, to move the display surface defined behind or in the window.
  • the guide bar and its display surface that is, the entire indicator, carry out the actuating movement of the actuating part.
  • the guide bar is forced to at least partially change its relative position to the operating part. This happens because the guide bar abuts against a stationary component, such as a fixed rosette and is stressed elastically.
  • the guide bar now executes a partial rotational movement for movement in the direction of actuation, which takes place about an axis of rotation which is oriented perpendicular to the actuation direction.
  • a part of the actuating force which is transmitted via the actuating part, deflected by the non-moving fixed component such that an elastic stress of the guide bar and thus a movement of the display surface takes place.
  • the display surface and the guide web are integrally formed.
  • the one-piece design requires no additional coupling point between the display surface and the guide bar.
  • the spring element is designed as a separate component.
  • the spring element is designed and placed in such a way that it can not tilt in the cylindrical body of the actuator.
  • another concept may be that the display surface and the guide bar are made of plastic. Plastic has the advantage that it is not subject to any aging process.
  • the display surface and the guide web are punched from a sheet metal strip. The production of the display surface and the guide web from a sheet-metal strip has the advantage that this is a very simple production and can be implemented without much effort.
  • a technical continuation of the inventive concept may consist in that the guide web is S-shaped, wherein at one end the display surface and at the other end a pin-like device for receiving the spring element are arranged.
  • the S-shaped design of the guide web causes the guide web to guide the guide web through the side walls formed in the cylindrical base body of the actuator, since in particular the S-shaped bulges of the guide web rest against the walls.
  • the spring element has a Aufsteck- opening, via which the spring element is arranged on the pin-like device of the guide web.
  • the AufStecgro réelle the spring element allows a fixed positioning of a pin-like device of the guide bar.
  • a further concept may consist in that the spring element has a tensioning lever, which bears against the guide web and acts on it with a spring force.
  • a technical continuation of the inventive concept may consist in that upon actuation of the actuator, the guide web including the display surface is provided to perform a rotational movement from outside to inside in the direction of the center of the actuator. This defined back and forth movement in the case of triggering and in the normal state allows a reliable indication of the respective state of the actuator.
  • the actuator according to the invention preferably a command and reporting device, has a cylindrical base body and a cap, in which at least one window is arranged, preferably a plurality are arranged on windows.
  • the at least one window is part of a mechanical display, which also comprises a display area, which informs the operator of the command and signaling device whether the command and signaling device is in the actuated or uncontrolled state.
  • the display surface is positioned at one end of a guide bar, which is guided inside the cylindrical body of the actuator.
  • a pin-like device is arranged, which engages in recesses of the cylindrical base body of the actuator, whereby a fixed point is formed, which is a rotary movement allows the guide bar in the direction of the center of the cylindrical body.
  • the guide web is acted upon by a resilient element, preferably a spring element or a rubber ring with a force which allows the return of the display surface from the actuated state to the unactuated state.
  • the elastic element can assume different embodiments.
  • the actuator according to the invention with a mechanical signal display is characterized by a robust, structurally simple construction, which enables reliable operation and is also inexpensive to implement, as can be dispensed with stamped and bent parts.
  • the structural design of the display allows pre-assembly, which contributes to an overall relief in the assembly of the entire device.
