Definitions

  • Such push button devices are already known (DE-OS 33 29 698); there the guide link is formed by double scissors. As a result, reliable parallel guidance of the key head relative to the guide body is achieved even with comparatively large key heads. Such parallel guidance ensures that regardless of the point at which the key is depressed, the desired switching process is triggered without the key head jamming or jamming.
  • Pushbutton devices are also known in which a bracket is provided as a guide member. Such a guide member is mostly used with very long key heads.
  • the assembly of the button head carrying the guide member on the guide body is cumbersome. Because the movable guide member must be inserted from the edge into the engagement slots of the guide body, while the key top must be kept in an aligned position.
  • the object of the invention is to improve a push button device of the type mentioned in such a way that the button head with the guide member can be assembled and disassembled on the guide body in a simple manner and without impairing adjacent devices.
  • This object is achieved in that a latching device is formed on the push button device, which holds the guide member in a latching position, that in the latched position with the button head placed on the guide body, the first stop area of the guide member lies in front of openings in the engagement slots and that by depressing the button head on the guide body, the guide member passes from the latched position into the operating position, the first stop region coming into the engagement slots.
  • the button head can be pulled off with the guide member upwards. This means that the position of the button head relative to the guide body, e.g. can be changed by moving or turning the button head. This is advantageous if one of several switch contacts provided in the guide body or in the grid can be actuated with the button head.
  • a push button device has a button head (1).
  • a cylindrical key tappet (2) is formed on this.
  • the button head (1) is assigned a guide body (3) which is composed of the same symmetrically designed guide body parts (3 ', 3 ⁇ ).
  • a guide sleeve (4) for the key tappet (2) is formed on the guide body (3).
  • the guide body (3) is attached to a plate (5) on which a switching film (6) is arranged.
  • a switching dome (7) of the switching film (6) lies in the base of the guide sleeve (4).
  • a pair of scissors (8) is provided as a guide member, which has two arms (9, 10).
  • a pin (11 to 14) is formed at the two ends of each arm (9, 10).
  • a receptacle (15) is provided on the key top (1), in which a bearing shell (16) for the pin (12) is formed.
  • the pin (12) is thus rotatable in the receptacle (15), but is mounted immovably.
  • a receptacle (17) for the pin (14) of the arm (10) is also provided on the button head (1).
  • a locking cam (18) is formed in the receptacle (17). This forms on the one hand a stop surface (19) and on the other hand a stop surface (20) for the pin (14) (cf. FIGS. 1 to 4).
  • a stop (22) is formed in the region of the articulation point (21) of the scissors (8). This prevents the arms (9, 10) from being able to be moved further towards one another in the direction of the arrows (A) than is shown in FIG. 1.
  • a further stop surface (23) is provided instead of the stop (22) in the receptacle (17).
  • a latching cam (18) with stop faces (19, 20) and a stop face (23) is provided in the receptacle (15) instead of the bearing shell (16).
  • the design of the receptacle (15) thus corresponds to the design of the receptacle (17).
  • engagement slots (24, 25) are formed, which have openings (26, 27) on one side.
  • the scissors (8) on the button head (1) are brought into a detent position.
  • the arm (10) and thus also the arm (9) is blocked.
  • this is achieved in that the pin (14) bears on the stop surface (19) of the latching cam (18) and the arms (9, 10) abut one another on the stop (22).
  • this is achieved in that the pin (14) between the stop surface (19) and the stop surface (23) is held.
  • this is achieved in that the pin (12) is also held in the receptacle (15) between the stop surface (19) and the stop surface (23).
  • the key head (1) is then aligned with the scissors (8) in the locking position on the guide body (3).
  • the key tappet (2) engages in the respective guide sleeve (4).
  • the pins (11, 13) lie at the openings (26, 27) of the engagement slots (24, 25) and then stand on the bottom of the engagement slots (24, 25).
  • the button head (1) is now in its operating position (see FIG. 2). From the operating position, the button head (1) is pushed in by pressing the arrow (B) bring his switching position in which the push button (2) depresses the switching dome (7) so that electrical contacts arranged in it are closed.
  • the pins (11, 13) move in the engagement slots (24 and 25) in the direction of the arrows (C).
  • the pin (14) moves accordingly in the receptacle (17).
  • the pin (12) in the receptacle (15) also shifts accordingly.
  • the button head (1) is reset from the switching position to the operating position by the spring elasticity of the switching dome (7).
  • the return movement into the operating position is limited by the striking of the pin (14) on the stop surface (20) of the latching cam (18).
  • the key head (1) If the key head (1) is to be removed, it is pulled up in the opposite direction of the arrow (B).
  • the pin (14) snaps over the stop surface (20) so that it comes back into the position shown in FIG. 1.
  • the pins (11, 13) lie in the openings (26, 27) so that the key top (1) can be removed from the guide body (3) with the scissors (8).
  • the scissors (8) can automatically move into the locked position.
  • the button head (1) with the scissors (8) can then be rotated against the guide body (3) so that the switching plunger (2) engages in the guide sleeve (4 ') of the guide body part (3') and is accordingly assigned to another switching dome .
  • the guide member is formed by a bracket (28).
  • the bracket (28) has pins (12, 12 ') which are rotatably mounted in receptacles (15) of the key head (1).
  • humps (30, 30') are formed, which depressions (31, 31 ') of the button head (1) are assigned.
  • the legs (29, 29 ') are further provided with pins (11, 11').
  • engagement slots (24, 24') are formed for the pin (11, 11 ') on the guide body (3).
  • the humps (30, 30 ') engage in the depressions (31, 31'). If the button head (1) is placed on the guide body (3), then the pins (11, 11 ') are in front of the engagement slots (24, 24') in the latched position of the bracket (28).
  • the cusps (30, 30 ') disengage from the recesses (31, 31') and the pins (11, 11 ') enter the engagement slots (24, 24').
  • the button head (1) is then movable between its operating position and its switching position.
  • the humps (30, 30 ') are freely movable in free spaces (32, 32').
  • the recess (31, 31 ') forms the stop surfaces (19, 20, 23) for the hump (30).
  • the hump (30) lies between the stop surfaces (19, 23).
  • the button head (1) returns from the switching position, the hump (30) hits the stop surface (20). The same applies to the hump (30 ').
  • the bracket (28) is a wire bracket. Its ends form the pins (11, 11 ').
  • the bracket (28) has leg sections (32, 32 '), which groove-shaped depressions (31, 31') of the key top (1) are assigned. In the locked position, the leg sections (32, 32 ') are engaged in the recesses (31, 31') which form the abutment surfaces mentioned.
  • the mode of operation corresponds to that described above.
