Definitions

  • the invention relates to a device for locking a switch tongue with the features specified in the preambles of claims 1 and 2.
  • a corresponding device can be found in WO 95/03199.
  • the switch lock enables a switch tongue to be locked or opened using structurally simple measures, while at the same time being easy to move, which leads to a reduction in maintenance. It is also ensured that the locked switch tongue cannot be unlocked even if the sliding element is no longer properly grasping the locking clip or, if necessary, detached therefrom. No further details can be found in the prior art about the course of the forces acting during locking or unlocking.
  • the present invention is based on the problem of developing a device of the type mentioned at the outset in such a way that the forces required for locking the switch tongue can be set in a controlled manner, in particular can be kept small.
  • the locking force can be influenced in a controlled manner by changing the course of the support surface of the second roller element. At the same time, it is ensured that proper locking takes place, in particular overcoming a dead center in the support surface of the clamp counterpart following one or more curve segments, ensuring that an uncontrolled unlocking cannot take place after locking the switch tongue.
  • a starting piece 14 extends from the stock rail 10 in a known manner, which is penetrated on the one hand by a push rod 16 and on the other hand by a locking clip 18, preferably in the form of two mutually parallel angle levers, between which the push rod 16 extends.
  • the closure clip 18 is based on a clip receptacle 20 and is rotatably mounted in the latter about an axis 22.
  • the clamp receptacle 20 itself is preferably firmly connected in a known manner to the foot 24 of the switch tongue 12.
  • the closure piece 14 has a support surface 26 on which a first roller element 28 can be supported in the locked position of the switch tongue 12 and rolls on the latter in the manner described below.
  • the roller element 28 starts from an angled leg 30 of the locking clip 18.
  • the roller element 28, which is rotatably mounted about an axis 32, runs at a distance from the free end 34 of the horizontal section 30 of the closure clip 18.
  • a second roller element 36 is rotatably mounted about an axis 38, in a section 40 angled downward with respect to the stock rail 10 or switch tongue 12, so that the horizontally extending section of the closure clip 18 ) has a hook-shaped geometry with the second roller element 36 arranged at the end.
  • the second roller element 36 is guided in an L-shaped link slot 42 of the push rod 16.
  • the slotted slot 42 has a horizontally extending section 44 and a downward section 40, that is to say facing away from the stock rail 10 or switch tongue 12, which comprises a boundary surface 46 facing the stock rail 10 or switch tongue 12, on which the second roller element 36 supports and rolls along.
  • the push rod 16 can be supported on a further roller element 54, which starts from the closure piece 14.
  • the support surface 26 assigned to the first roller element 28 is composed of two curve segment sections 56 and 58, which are separated by a projection 60, which is to be referred to as dead center, and which the roller element 28 must overcome in order to be completely locked or locked to be able to be moved out of the unlocked position.
  • the dead center 60 ensures that when the switch tongue 12 is locked, uncontrolled unlocking cannot take place.
  • roller element 28 is not yet on the support surface 26, but lies against an edge 61, which acts in relation to the clamp bearing specified by the axis 22 as a clamp counter-bearing on which the roller element 28 is supported .
  • the locking clip 16 is supported via the roller element 50 running in the longitudinal slot 52 below the axis 22 of the locking clip 18, so that a supporting force P2 is formed.
  • the one running within the angled portion 44 second roller element 36 is supported on surface 46 with a force P3.
  • the first roller element 28 is supported on the edge 61 with a force P4.
  • the closure clip 18 itself is supported in its clip bearing with a force P5.
  • the tongue is supported on a sliding chair with a force P6.
  • a closing force P7 acts between the stock rail 10 and the switch tongue 12.
  • the distance between the stock rail 10 and the switch tongue 12 is greatest in comparison with the representations of FIGS. 2 to 7. During this locking, the first roller element 28 is always supported on the edge 61.
  • the distance is gradually reduced.
  • the forces P1 and P2 remain largely constant.
  • the force P4 in the bracket counter bearing 61 alone i.e. the contact surface between the first roller element 28 and the edge 61, changes both in amount and in the direction, so that the bracket bearing force P5, the supporting force P6 of the switch tongue and the closing force P7 change as a result to change.
  • the final locking i.e. the point at which on the one hand the first roller element rests on the curved segment 56 or 58 of the support surface 26 and on the other hand the second roller element merges from the support surface 46 into the horizontal section 44 of the link slot 42 Locking force P7 only slight. Only when the transition takes place and complete locking is carried out (FIG. 7) can a strong increase in the clamp bearing force P5 or the locking force P7 be ascertained.
  • the second roller element 36 rolls off onto a support surface 64 which encloses an obtuse angle vertically or even to the horizontal section 44 of the slot slot 42.
  • the second roller element moves upward when the switch tongue 12 is locked along the support surface 46, 64 in order to be in the horizontal section 44 of the L-shaped link slot 42 when the switch tongue 12 is locked.
  • the inclination of the support surface 46 or 64 must be selected so that the force passing through the connecting line between the axis of rotation 38 of the roller element 36 and the axis of rotation 22 of the locking clip 18 has a component running in the direction of the horizontal section 44 of the slot slot 42 which is larger than that frictional forces opposing the rolling motion.
