Definitions
- the invention relates to a device for locking of end positions of movable switch parts, especially switch locks, in which two are movable relative to each other Parts in a non-positive in at least one direction of movement Position are displaceable, with separate locking members are provided.
- EP-A-0 289 978 discloses a device for locking End positions of movable switch parts according to the generic term of Claim 1.
- the invention now aims to set up a device to create the type with which a completely closed and thus construction protected against the ingress of dirt is possible and which further impair the service life avoids eccentric loads on the locking members.
- the invention Training essentially in that relative to each other movable parts of one slidable along its axis Pipe and a guided in the pipe along its axis Bolts are formed that the pipe over part of its axial Lengths in the axial direction under formation of the locking members forming Has spring tongues, and that the free ends of the spring tongues a head with the wall thickness of the pipe Wear wall thickness.
- the training is made in such a way that the relatively displaceable parts in a fixed outer tube, which is guided on the inner jacket at least one axial area with increased clear width having.
- Such an outer tube encompasses in particular Locking member displaceable radially outward and can therefore also penetrate dust at this point or safely prevent contamination.
- Outer tube offers Outer tube as a self-contained further protected Component the possibility, if desired, as one preferred training corresponds to a displacement drive to be arranged, which can be arranged in the stationary outer tube can.
- Limiting the relative displacement of the interior, bolt-shaped, axially guided component in the pipe to the outside, tubular, axially displaceable component can be achieved in a simple manner in that the tubular, at least one part displaceable along its axis has inwardly projecting board, which with a stop on bolt-shaped part that moves along its axis cooperates.
- Such an inwardly projecting board also has the advantage that between the inwardly projecting board and a stop of the bolt-shaped that interacts with this board Component can be arranged a spring.
- a spring is designed as a coil spring and a such training can serve as a conversion aid, because during the adjustment process when assigning one according to the invention First set up both for each movable rail Springs are compressed, resulting in a dead center position and a spring expands again in the respective end position becomes.
- an appropriate design of the spring characteristic results support based on the respective dead center the changeover movement, with the further advantage being achieved is that an operated in this way or with such Locking switch equipped against the force of a Spring can be cut open.
- the training is made such that the bolt-shaped movable part over a part its length is reduced to a smaller diameter.
- the locking members in their radially inward shifted Position in the longitudinal direction of the bolt are shifted so that enables a lead or a lag of the adjustment movement in which a locking position is not yet is achieved. Only after rising over a conical surface the larger diameter of the bolt, the locking members can then dodge when they are in an appropriate ring groove or immerse the recess of the outer tube. Only in this second position enables locking.
- the training can be a wear-free shift to enable the locking members to be made so that the diameter difference between the smaller diameter of the bolt-shaped part and the inner diameter of the stationary Outer tube as well as the diameter difference between the larger diameter of the bolt-shaped part and the greater clear width of the excluded area of the stationary Tube is larger than the wall thickness of the head of the spring tongues.
- the training is preferably made so that the Wall thickness of the sliding part is greater than half Wall thickness of the head of the spring tongues.
- the closure according to the invention also acts directly as a drive use for the adjustment of a switch, with advantage the training is made so that one of the relative to each other axially movable parts, especially the bolt-shaped Part, is connected to a displacement drive, whereby for the arrangement of such a shift drive, as already mentioned above that stationary outer tube is particularly suitable.

- FIGS. 13 to 16 representations of a modified one Embodiment in a manner analogous to FIGS. 1 to 4.
- the outer tube 1 is arranged in a stationary manner and is relative to one another movable parts, i.e. the tube 2 and the bolt 3, are with a movable rail part and / or with a drive connected, as shown in the following figures will be clearly visible.
- the pipe 2 and the bolt 3 act together via locking members 4.
- the outer tube or Housing 1 is closed at its front end 5, with seals between the tubular slidable part 2 and the Outer tube 1 or the front end 5 and between the bolt 3 and the tube 2 can be provided. Such seals are with 6 and 7 indicated.
- the bolt 3 has a portion 8, the outer diameter corresponds to the inner diameter of the tube 2.
- the bolt 3 then has a stepped portion on the partial area 8 Area defining stop 9, which with a board 10 of the tube 2 when the bolt 3 is moved after a predetermined displacement path cooperates. After a shift of the bolt 3 in the direction of arrow 11 arrive at one Interaction of the stop 9 with the board 10, the locking members 4 in an area which is again of a separate design 12 of the bolt and allow a further displacement movement the bolt 3 and the tube 2 in the direction of arrow 11.
- Die Locking members 4 come in when pivoting radial direction outwards in an annular groove 14 Interaction of the stop 9 with the board 10 and one subsequent possible displacement of both the bolt 3 and the pipe 2 also gives the possibility of a lead or caster during a changeover movement of a movable switch part, as this becomes clearer from the following figures will be apparent.
- the device is for locking end positions of movable switch parts in a shifted in the direction of arrow 11 according to FIG Position and it can be clearly seen that the bolt 3 through Interaction of the stop 9 with the rim 10 of the tube 2 also a sliding movement of the tube 2 in the direction of the arrow 11 has caused. Because after a first shifting movement of the bolt 3, the locking members 4 in the offset To reach area 12 of the bolt is to move the tube 2 possible via the position shown in Fig.1.
- a switch is shown schematically, the change the tongue rails 15, 16 in one each to the Stock rails 17, 18 adjacent position over a plurality of generally carried out with 20 designated closures, each the device shown in more detail in Figures 1 to 4 have, as shown in more detail in the following figures is.
