Definitions
- the invention relates to a safety switch with a housing which accommodates a switching device which can be actuated by an actuator which can be unlocked by means of a key which can be inserted into the housing and which can be displaced by a predetermined stroke by the key for actuating the switching device.
- Such a safety switch or the like, in particular for protective covers. used for personal protection is known for example from EP-PS 0 175 156.
- This has a housing in which the closing and opening of the contact by the like on the protective cover. attached key serving as an actuator is effected.
- the latter actuates a switching drum, which is turned by the key from its rest position and thereby causes the closing and opening of the contact after its two axially displaceable roller parts have first been pushed apart by the key in order to unlock the roller for rotation.
- a relatively complicated key is used here, it is the same for all types of this safety switch and is not individually designed.
- the object of the invention is to provide a safety switch of the type mentioned, which can only be operated with an individual key.
- a slot extending in the direction of insertion is arranged in the housing, which receives the actuator and in which a plurality of springs with their axes arranged parallel to one another and perpendicular to the direction of insertion of the key and spring-biased in the direction of the inserted key Pins protrudes, at least some of which locks the actuator with respect to the housing, the key having a coded pattern of receiving openings corresponding to the locking pins for unlocking the actuator and the pins being codable accordingly.
- Fig. 1 shows a schematic and perspective cut open an embodiment of a safety switch.
- FIG. 2a to 2c show the safety switch of Fig. 1 in section in different positions during operation.
- Fig. 3 shows schematically and cut open perspective another embodiment of a safety switch.
- Fig. 4a to 4e show the safety switch of Fig. 3 in section in different positions during operation.
- the safety switch shown in Fig. 1 comprises a housing 1 which receives a block-shaped insert 2 which is provided with a plurality of parallel bores 3 arranged one above the other in two rows. Adjacent to a wall of the housing 1 is a wall 4 connected to the insert 2, which closes the bores 3 to the adjacent wall of the housing 1.
- the bores 3 open into a slot 5 which extends through the insert 2 perpendicular to the axes of the bores 3.
- the holes 3 each receive a pin 6.
- the pins 6 each comprise a foot piece 7 and, separately therefrom, a rounded head piece 8.
- the foot piece 7 has a blind hole for receiving one end of a compression spring 9, which is supported at the other end on the wall 4 and the associated pin 6 in the direction of the opposite wall of the housing 1 and presses so that the pins 6 can protrude with their head pieces 8 out of the holes 3 into the slot 5.
- the insert 2 with the spring-loaded pins 6 can be inserted into the housing 1 pre-assembled.
- the actuator 10 In the housing 1 is an essentially plate-shaped actuator 10 adjacent to the open ends of the holes 3 in the slot 5.
- the actuator 10 has a foot part 11 which is connected in an articulated manner to a plunger 12, in particular a straight plunger, of a switching device 13 arranged in the housing 1.
- the actuator 10 is movable along the adjacent end face of the insert 2 and has a series of through openings 14 for the pins 6. In the locked starting position, the pins 6 extend through the adjacent through opening 14 because the through openings 14 are in the locked position of the actuator 10 (Fig. 2a) are aligned with corresponding holes 3.
- the actuator 10 which is preferably guided on its two narrow sides, does not take up the full width of the slot 5, but leaves enough space to be able to insert a key 15 parallel to the actuator 10 via a corresponding slot 16 in the housing 1.
- the matching key 15 is provided with a pattern of receiving openings 17 in accordance with a coding provided.
- head pieces 8 of different lengths are used in such a way that part of the head pieces 8 has a length corresponding to the width of the slot 5 and another part has a shorter length.
- the shorter head pieces 8 lock the actuator 10 in the starting position (FIG. 2a), the longer head pieces 8 couple the actuator 10 with the key 15 in its inserted position (FIG. 2b) by falling into the receiving openings 17 of the latter, and also serve as a driver when pulling out the key 15.
- the key 15 has no receiving openings 17, so that in the inserted position of the key 15 the end faces of the foot pieces 7 of the Head pieces 8 are aligned with one another and with the adjacent wall of the slot 5 (FIG. 2b).
- the key 15 If the key 15 is now inserted, it presses the pins 10 which lock the actuator 10 and protrude from this with their head pieces 8 into the remaining part of the slot 5 with its leading, correspondingly bevelled edge against the force of the springs 9 back.
- the pins 6 When the key 15 arrives at the foot piece 11 of the actuator 10 (FIG. 2 b), the pins 6 have fallen into the receiving openings 17 of the key 15 and the key 15 has been pushed in further, since then the head pieces 8 are entirely from the actuator 10 and key 15 are recorded and carried along, possible and leads to actuation of the switching device 13 (Fig. 2c).
- the longer head pieces 8 not received by receiving openings 17 will lock the actuator 10 with respect to the insert 2.
- the actuator 10 is also not to be unlocked.
- the actuator 10 When the key 15 is withdrawn, the actuator 10 is withdrawn due to the head pieces 8 serving as drivers, until its foot part 11 strikes the insert 2. Then the key 15 is further pulled out, with the actuator 10 being locked, in the reverse order of insertion.
- the lengths of the head pieces 8 are to be chosen correspondingly shorter.
- pins 6 with head pieces 8 of the same length are used, while the foot pieces 7 also have the same length as in the previous embodiment.
- the actuator 10 is also additionally provided with a slot 18 and, in addition to each pin 6, a ball 19 is arranged adjacent to the respective head piece 8. The balls 19 are pressed by the pins 6 against the opposite wall of the slot 5 (FIG. 4a), the head pieces 8 extending over the width of the slot 18.
- the coding takes place here via a coding card 20 (FIG. 4b) which is inserted into the slot 18 and which has passage openings 21 in accordance with a coding provided.
- the thickness of the encoding card 20 is approximately the width of the width remaining between the actuator 10 and the opposite wall of the slot 5 less than the width of the slot 18.
- the pressing is also carried out.
- the thickness of the coding card 20 and the key 15 are expediently chosen to be somewhat smaller than or equal to the radius of the balls 19.
- Coding pieces 19 may be provided, of which those which do not fall into receiving openings 17 of the key 15 are designed as balls.
- the foot pieces 7 can also be omitted and the springs 9 can attack the head pieces 8 directly.
