Definitions

  • the invention relates to a device for locking end positions of movable switch parts, in particular switch lock, in which two parts movable relative to one another can be displaced in a position that is non-positive in at least one direction of movement.
  • DE-A-1 755 894 discloses a switch closure device which comprises two clamping claws which are to be clamped to a rail foot by means of a hollow screw.
  • a rotating bolt is mounted in the banjo bolt, on which a locking bolt sits.
  • the rotary latch can consist of telescopically interlocking parts in order to be adjusted to the span of the two clamping claws.
  • the fixed banjo bolt and the rotatable rotary bolt form two parts which are movable relative to one another, the banjo bolt forming a tube, the rotary bolt a bolt and the locking bolt a locking member.
  • the so-called clamp tip lock has become known for locking movable switch parts, in particular in the form of a switch lock.
  • two parts which are movable relative to one another are provided, one part being guided in a recess in the other and having to be pivoted relative to the other part in the displacement plane in order to take up the two respective operating positions.
  • pivoting from the plane of displacement is required.
  • all known switch locks are designed so that a more or less complex off-axis movement is required and that the parts causing the lock are exposed and thus exposed to contamination. In particular, the risk of contamination can hinder a secure locking.
  • the design according to the invention essentially consists in the fact that the parts which are displaceable relative to one another are formed by a tube and a bolt guided in the tube and are only displaceable relative to one another in the outer tube in the axial direction and that separate locking members which are connected to one another in relation to one another movable parts and cooperate with the outer tube, such as balls or rollers displaceable in the radial direction, are provided.
  • the fact that the parts which are displaceable relative to one another can only be displaced relative to one another in the axial direction, since one of the two parts is guided by a component which is guided axially in the other part, the risk of eccentric and eccentric forces avoided, whereby the fact that one of the components is a tube and encompasses the other component enables a completely closed and protected against the ingress of dirt.
  • the locking itself takes place in such a design by separate locking members, which can be formed by balls or rollers. In the case of rolls, these must of course have a relatively small axial length and be rotatably supported about axes which cross the longitudinal axis of the bolt or the pipe, in order not to hinder a displacement of the two components into one another.
  • the locking members can be dimensioned so that they roll during the shift between the inner contour of the outer component and the outer contour of the inner component, the locking can be achieved by radial displacement of the balls or rollers.
  • the design is such that the parts which are displaceable relative to one another are guided in a stationary outer tube which has at least one axial region on the inner jacket with an enlarged internal width.
  • a stationary outer tube which has at least one axial region on the inner jacket with an enlarged internal width.
  • Such an outer tube encompasses, in particular, a locking member which can be displaced outward in the radial direction and can therefore also reliably prevent dust or dirt from penetrating at this point.
  • such an outer tube as a self-contained further protected component offers the possibility, if desired, as in a preferred embodiment, to arrange a displacement drive, which can be arranged in the stationary outer tube.
  • the locking is effected in a particularly simple manner by the locking members which can be displaced in the radial direction in such a way that the part formed by a tube and displaceable along its axis has radial openings for receiving the locking members.
  • a limitation of the relative displacement of the internal, bolt-shaped, axially guided component in the tube to the external, tubular, axially displaceable component can be achieved in a simple manner in that the tubular, displaceable part along its axis has at least one inwardly projecting rim, which with interacts with a stop on the bolt-shaped part which is displaceable along its axis.
  • Such an inwardly projecting board also has the advantage that a spring can be arranged between the inwardly projecting board and a stop of the bolt-shaped component cooperating with this board.
  • Such a spring is advantageously designed as a helical spring and such a design can serve as a changeover aid, since during the adjustment process, when a device according to the invention is assigned to each movable rail, both springs are first compressed, which results in a dead center position and a spring in the respective end position is expanded again.
  • the changeover movement is supported from the respective dead center position, with the further advantage that a switch operated in this way or equipped with such a closure member can be cut open against the force of a spring.
  • the design is such that the bolt-shaped displaceable part is offset to a smaller diameter over part of its length.
  • the locking members can roll in their radially inwardly displaced position in the longitudinal direction of the bolt, so that a lead or a lag of the adjustment movement is made possible, in which a locking position has not yet been reached. Only after the run-up over a conical surface on the larger diameter of the bolt, can the locking members evade when they can pass through the openings in the tubular, external component which is displaceable in the axial direction and can, for example, be immersed in a corresponding annular groove or recess in the outer tube. Locking is only possible in this second position.
  • the training can hiebei to allow a contact-free rolling of locking members on the respective outer surfaces, so that the diameter difference between the smaller diameter of the bolt-shaped part and the inner circumference of the stationary outer tube as well as the diameter difference between the larger diameter of the bolt-shaped part and the area of the stationary tube which is recessed to a larger clear width is larger than the diameter of the locking members.
  • the design is preferably such that the wall thickness of the displaceable tubular part is greater than half the diameter of the locking members formed by balls or rollers.
  • the locking in the embodiment according to the invention takes place in that the locking members can pass through the openings in the tubular component which is movable in the axial direction, a locking position being achieved when the balls displaced outward in the radial direction in this way into a Immerse the ring groove or recess on the inner circumference of the stationary outer tube.
  • the design is such that the stationary outer tube has at least two annular grooves arranged at an axial distance from one another on the inner circumference.
  • the closure according to the invention can also be used directly as a drive for the adjustment of a switch, the design advantageously being such that one of the axially displaceable parts, in particular the bolt-shaped part, is connected to a displacement drive , whereby for the arrangement of such a shift drive, as already mentioned above, that the stationary outer tube is particularly suitable.
