Definitions

  • the invention relates to a linear by manual pressing against the force of a spring from a first stable position to a second stable position (depressed position) and under the force of the spring back sliding push button for actuating the pivotally mounted contact lever of an electrical switching device according to the preamble of claim 1.
  • Linearly displaceable push buttons are known, for example, in ballpoint pens become.
  • go out and moving and rotating part axially extending slots are provided, which are different lengths and molded with on the inner surface of the ballpoint pen sleeve Engage teeth; when the teeth in the axially longer slots slide in, the pen refill disappears inside the sleeve and when after pressing the push button, the teeth engage in the shorter slots, then protrudes the ballpoint pen refill from the ballpoint pen sleeve, so that the ballpoint pen is ready for use.
  • a push button of the aforementioned type has become known from FR 2 322 442.
  • This arrangement is because it is used in a push button for a small button, not robust enough for many applications.
  • the object of the invention is to design a push button of the type mentioned above, that a correct movement of the locking element to the partition wall always is ensured and that while also a sufficient robustness of the push button achieved.
  • the second sliding surface is at least in that of the pressing surface facing away connecting portion to the first sliding surface based on these by the third level increased.
  • According to another embodiment is located between the first sliding surface and the Gleitzinabites, which lies in the region of the Racksackes, a first stage, with the sure is achieved that, when the locking element is in the latching bag, when depressing the locking element can not move into the first sliding surface.
  • the locking element has a Snap-in lever with a nose extending perpendicularly about an axis, the is perpendicular to the Gleit vomebenen, is pivotally, which is achieved that the nose can also run around safely when pressing around the partition. So that the nose remains on the sliding surfaces, a first spring is provided, which the Keep holding lever in the direction of sliding surfaces. In addition, a second spring provided, which the latching lever about the axis perpendicular to the Gleitzinelement runs, applied in one direction, so that a circulation of the nose up the sliding surfaces is ensured around the partition in each case.
  • the latching lever is mounted on a rotatably mounted Holding pin formed, which is slidably movable in its own axis and on which the spring acts, so that the nose is pressed against the sliding surfaces.
  • Holding pin formed, which is slidably movable in its own axis and on which the spring acts, so that the nose is pressed against the sliding surfaces.
  • the path of movement of the holding pin is dimensioned so that the nose of the Sliding surfaces on the partition wall can be abdgurbar.
  • the latter solution is used when the push button as Actuator in a line or residual current circuit breaker use should find. Then that is the Rasthaltehebel or latching lug in the case of Overcurrent or a short-circuit current or a fault current to be moved so that she did not get into the bag; at a correspondingly constructive Design of the latching lever or the retaining pin of a contact lever be moved so that the nose can slide over the partition, what is effected by the second spring.
  • a push button 10 of Fig. 1 comprises a cylindrical portion 11 whose non-visible, lying in the drawing surface (at 12) has a pressing surface.
  • On the opposite circular surface 13 of the cylindrical portion includes a first projection 14 and a second projection 15, which has an approximately rectangular shape and on which on one of the broad sides of a sliding surface assembly 16 is provided.
  • the sliding surface arrangement 16 has an approximately parallel to the direction of movement of the push button 10 extending first sliding surface 17 and a parallel thereto extending second sliding surface 18, which are connected in their squeegee side region via a connection point 19 and also via a press surface on the downstream connection point 20.
  • the first sliding surface rises slightly from the connection point 20 up to one in the region of the connection point 19 located saddle surface 21, which drops to the actual junction 19 via a step 22.
  • the connection point 19 drops off to the second sliding surface 18, which rises up to the connection point 20 relative to this reference plane, so that a third step 24 is provided at the connection point 20 between the second sliding surface and the first sliding surface the second sliding surface to the first sliding surface 17 drops.
  • a partition wall 25 which is provided on the connection point 19, so the pressing surface near junction 19 with a latching bag 26.
  • the detent moves in the direction of arrow P 2 and is deflected over the gradation 27 and the further step 23 toward the second sliding surface 18 and then slides when the push button slides back up on the second sliding surface 18 to the second connection point 20 and snaps over the step 24 again on the first slide 17.
  • the guide of the locking lug thus takes place through the partition wall 25, the gradation 27 and a parallel to the partition 25 extending boundary wall 29, between which the second sliding surface 18th runs.
  • the boundary wall 29 has in the region of the connection point 20 to the sliding surface 17 inclined toward arc 30. In the movement P 3 , the latching lug between the boundary wall 29 with the sheet 30 and the partition wall 25 is guided on the sliding surface 18.
  • the locking element thus makes a movement perpendicular to the reference plane and also a Drehbwegung about a rotation axis, the vertical to the reference plane.
  • a second spring is provided, the spring force counteracts the locking element Turns clockwise or acted upon, so that the latch 34 on the Partition 25 along on the sliding surface 17 to the latching bag 26 and from there along the boundary wall 29 slides to the starting point at the junction 20 (see also Fig. 3).
  • the first projection 14 includes an arm 31, to which a perpendicular thereto and perpendicular to the direction of movement of the push button 10 extending pin 32 connects (see below).
  • the projection 15 is an axially extending Bore 33, in which a compression spring is arranged (not shown), the push button 10 pushes up.
  • the Eindrückrison is the movement in the direction of arrow E and the expression movement is the movement according to arrow direction A. The movement E takes place manually and the movement A due to the located in the bore 33 Spring.
  • Figs. 2 and 3 show the push button 10 with the sliding surface 17 on which the sliding element 34 and latching element 34 slides along.
  • This locking element 34 has a Nose 35, which is at an approximately parallel to the direction of movement of the push button 10th extending arm 36 is integrally formed with a transverse thereto bolt 37th connected is; the bolt 37 is slidable in its axial direction, so that the Arm 36 is slidable; Moreover, the bolt 37 is also rotatable about his Longitudinal axis, so that the arm 36 is pivotable about the pin axis 37.
  • FIG. 3 shows the latching arm 36 with the locking lug 34 at the second connection point 20.
  • FIG. 1 or 2 to 13 it has been indicated above that the arrangement of FIG. 1 or 2 to 13 at a circuit breaker is used.
  • a rotary axis 38 a contact lever 39 is rotatably mounted, which is a movable Contact piece 40 has and on the opposite side a stop 41, the abuts against the end face of the bolt 37.
  • Figs. 2 and 3 show the arrangements in the off position, so if the Push button 10 protrudes completely from the switching device.
  • the latch 35 is located itself at the junction 20.
  • the movable contact piece is in his Off position.
  • To turn on the push button 10 is pressed in the direction of arrow E, whereby a not shown in the figures switching mechanism arrangement, with the push button is in communication, the movable contact lever 39 in the contact position with a fixed contact piece 41 passes.
  • the locking element 35 is located on the sliding surface 17 but still at a certain distance to the junction 19th If the push button 10 is pressed further, then the latch 35 is in the area the connection point 19 snap into the locking bag 26; one recognizes in Fig.
