Definitions

  • the invention relates to a command button in disk element design with an actuator which has a housing which can be built into a supporting wall and a hollow plunger which can be reset by means of a spring, the outer end of which is designed as a push button which can be illuminated from the inside, with a coupling piece which has several slots for receiving has parallel to be arranged disc-shaped elements, and with elements that u. a. are designed as switching elements with a movable member which is displaceable in the plunger movement direction and can be actuated by the plunger and with at least one contact set or as a lighting element with a lamp holder or other lighting unit.
  • a well-known control buttons of this type is sold under the trademark RAFIX S 22 by the company Rafi GmbH & Co. and is shown in the annexed leaflet.
  • the actuator designated as the actuator has a round push button, the coupling piece referred to as the clutch has three slots.
  • the switching elements are referred to as contact elements.
  • Your mobile organs have a flat, top protruding end and each carry a contact bridge, which acts as a break or make contact depending on the type of switching element concerned.
  • the connection terminals are located on the underside facing away from the viewer.
  • the light element which can only be attached to the middle slot of the coupling piece, only contains the connection terminals for the lamp holder attached above.
  • the plunger only reaches the movable organs of the switching elements when they are inserted in the outer slots. If the lighting element can be dispensed with and a third switching element is desired, this can be inserted instead of the lighting element in the middle slot, but then disadvantageously a special pressure piece has to be inserted into the plunger in order to fill its end face in the center, so that the movable one Organ of the middle switching element is reached and moved by the plunger.
  • command buttons are used for manual control of motor drives with opposite directions of rotation, the following problem arises, for example when the motor opens and closes a gate and, as usual, a command button is provided for each direction of rotation, which has an "opener” switching element and one "Normally open” switching element is equipped.
  • the NC contact in the "clockwise” command button interrupts the circuit for counterclockwise rotation and vice versa (electrical locking). It can happen that the working contact bridge is welded to its counter contact pieces and gets stuck when the push button is released. The one contained in the other switching element However, the opener returns to its rest position and thus no longer fulfills its locking function.
  • the known command button is therefore not suitable for switching arrangements in which certain dependencies between the individual switching elements have to be observed.
  • the invention has for its object to propose a command button of the type described in the introduction, the actuator does not require a special pressure piece or other additional part if a switching element is inserted in the middle slot instead of the lighting element.
  • the command button should also be usable for circuits with electrical locking.
  • the movable members of the disc-shaped elements can be coupled together.
  • This can be achieved by an insertable cross-connection or, in particular, in that recesses and / or projections protruding perpendicular to the plane of the disc are provided on the side surfaces of the movable members parallel to the plane of the disc and engage in the recesses.
  • the movable member of the switching element which is seated at the central slot in the plunger axis can be moved by the movable member of at least one switching element attached next to it.
  • the light-emitting element can also have a loosely movable element which only serves to couple the switching elements which connect on both sides to one another, for example if they function as openers and closers within an electrical locking circuit. It is also possible to provide more than three slots on the coupling piece, the switching elements inserted further out also being driven via corresponding couplings. The number of elements to be arranged next to one another is thus no longer limited and an additional part for changing the end face of the actuator plunger is no longer required.
  • a particularly expedient embodiment of the coupling arrangement consists in that a projection and a recess at the same height and at the same distance from the transverse median plane and on the other side surface in alignment with the projection are provided on the movable members on one side surface. It is achieved in that two elements can be coupled both with mutually facing projections and in such a way that the projection of the one element in the further recess of the other element. When assembling a package of several elements, one can ensure that there is no protrusion at the ends.
  • the invention enables an essential further development of a generic command button, which consists in the fact that a special disk-shaped element is provided, which has a movable organ and a mechanism for locking it up and down.
  • This element can be added to any slot of the coupling piece, which ensures that all switching elements coupled to it take over the locking function. It is therefore advantageously no longer necessary to replace the actuator with an actuator with high and low latching, but it suffices to add the latching element to an empty slot or to replace one of the previous elements with the latching element.
  • the element with the up and down latching of its movable member can advantageously also be designed as a lighting element in such a way that a lamp holder is arranged above the movable member.
  • the locking mechanism is thus moved by the actuator into the lighting element. This significantly improves the use of space.
  • the invention creates an extraordinarily variable and versatile command button system, which simplifies assembly and relieves the need to hold stocks with fewer individual parts.
  • the command button according to FIGS. 1 to 3 is attached with its actuator (1) to a supporting wall (2), for example a control panel or a device housing.
  • the actuator housing is divided into a widened head (3) and a cylindrical socket (4), the latter of which is inserted through the supporting wall (2) and fastened by means of a screw ring (5).
  • a hollow, cylindrical plunger (6) is slidably guided in the socket (4).
  • the plunger face (see also Fig. 3) is widened like a flange.
  • the plunger (6) is designed as a push button (7). It is kept in the position shown by means of a spring (8).
  • a coupling piece (9) is fastened in a suitable manner to the connecting piece (9) and is designed such that one to three disk-shaped elements (10, 11, 12) are optionally attached to it in a parallel arrangement can be, preferably by detachable connectors.
  • the arrangement is such that the middle element, in the example a lighting and locking element (11), occupies the middle slot in the extension of the actuator axis.
  • a lamp holder (13) for an incandescent lamp (14) (FIG. 1), which sits on top and which is in the hollow plunger (6) protrudes and illuminates the touch field of the pushbutton (7), a movable member (15) mounted displaceably in the tappet movement direction and a latching mechanism (16) which interacts with it.
  • the movable member (15) has a transverse, rectangular receiving opening (17) which is accessible through rectangular windows (18) on both broad sides of the element housing in any position of the movable member (15).
  • the respective movable member (19) is also shown in FIGS. 8 and 9. It protrudes with its square upper end over the element housing and is pressed down by pressing the push button (7) from the end face of the plunger (6).
  • the return spring as well as the contact sets, d. H. depending on the embodiment, one or more break contacts or make contacts are not shown in the schematic illustration.
  • the movable members (19) have on one side a projection (20) of rectangular cross-section which projects perpendicularly to the disk surface. Immediately next to this projection there is a receiving opening (21) of the same size, which can pass through or, in the example, extends to the central plane of the switching element parallel to the disk surface.
  • each of the movable members (19) also has a receiving opening (22) which is aligned with the projection (20) and has the same cross section as this.
  • Windows (18) on both sides of the element housing allow - as with the lighting element - access to the receiving openings (21 and 22) and the passage of the projection (20).
  • the windows (18) are extended downwards by the stroke length, so that the lifting movement of the movable member (19) is not hindered.
  • the elements (10 to 12) according to Figures 1 to 3 are arranged so that the projections (20) of the two switching elements (10 and 12) from both sides in the receiving opening (17) of the movable member (15) of the light and Engage the locking element (11). As a result, these three movable organs are coupled together.
  • the movable member (15) follows all the movements of the other two movable members (19).
  • the movable organs (19) are locked when the movable organ (15) is locked with the aid of the Locking mechanism (16) held in the lower or upper position.
  • Both switching elements (10 and 12) thus act latching, ie as a switch. If you press the push button (7), they move downwards and are held there by the locking mechanism (16).
  • the three elements (10 to 12) are assembled in such a way that they are first inserted into one another perpendicular to the disk plane and then the entire block is inserted into the coupling piece (9) in the direction of the tappet movement and is, for example, latched.
  • the latching mechanism (16) and the movable member (15) are omitted from the lighting and locking element (11), one has a pure lighting element, as is known per se.
  • the two switching elements then work groping, i. H. after releasing the push button (7) they go back to the starting position each time.
  • a further switching element (25) can be inserted in the center instead of the lighting element (11), as shown in FIG. 11. It is coupled with its neighboring elements on both sides and all three movable organs work together in a groping function.
  • the equipping according to FIG. 4 can also be carried out in such a way that although the lighting and latching element (11) is attached in the middle and one switching element (10) is coupled to it, the other switching element (12) is inserted in a side-by-side manner is, so that the projection faces away from the lighting and locking element and stands outwards.
  • the switching element (10) is latching and the switching element (12) is latching.
  • the element housing (30) made of insulating material consists of two matching half-shells, of which only the rear one is shown.
  • Two metal brackets (31) and (32) are inserted into the housing. They have clamping fingers (33) at their upper angled end. The clamping fingers of one bracket connect it to the bayonet fitting socket (13) and the other bracket (32) is connected in the same way to a leaf spring (34) which forms the other connection for the incandescent lamp.
  • the lower ends of the metal bracket are provided with a screw thread and cover plate (35) for connecting lead wires.
  • a locking slide (36) is mounted so that it can move back and forth in the element housing (30). It is under the influence of two pressure springs acting against each other (37). Furthermore, the movable member (15) is movably mounted in the element housing in the direction of movement of the plunger of the command button.
  • the movable member (15) comprises the locking slide (36) in a fork shape. At the end of at least one fork tine, a pin (38) is inserted transversely a groove in the form of a heart curve on the locking slide (36) interacts. The shape of this heart curve is described in principle in DE-PS 11 69 549. This arrangement, as explained in the cited patent, causes the movable member (15) to be locked up and down, taking into account that this is due to the coupling to a switching element under the action of the return spring of the movable member (19) of this switching element .
