Definitions

  • the invention relates to a device for locking a switch tongue with a stock rail comprising a starting piece from the stock rail, which can be pushed through by a sliding element such as a push rod and an interacting locking element such as a locking clip, which in turn with the with its rail foot on a base such as
  • the sliding chair which can be supported and is displaceably connected on this displaceable switch tongue is pivotable in such a way that the closure element can be pivoted about an axis running in the longitudinal direction of the switch tongue, preferably above the rail foot, with the closure element between the sliding element and the closure piece being able to be fixed in a support region running beneath the stock rail foot when the switch tongue is in contact is and wherein the fixing can be effected by a resultant force extending between the support region and the axis.
  • the pivot axis of the lock clamp runs below the base of the stock rail, so that in the locked position approximately a force component running parallel to the sliding chair acts on the switch tongue, by means of which the contact is ensured. Since the pivot point of the clamp runs below the rail foot, the tongue is twisted at the same time, which leads to a gaping between the stock rail and the switch tongue. This twisting becomes greater the stronger the force is applied. The switch tongue is not held down with this type of force application without additional aids.
  • the resultant force causing the switch tongue to rest on the stock rail, which runs between the axis and the support of the locking clip running below the base of the back rail, runs in such a way that the vertical force component of the base on which the switch tongue is pushed back and forth into such a large size Distance from the rail foot cuts that the greater the resultant force, that is, the more the locking clip pulls the switch tongue towards the stock rail, the more the switch tongue is tilted, that is, a gap between it and the stock rail gapes.
  • the object of the present invention is to develop a device of the type described at the outset for locking a switch tongue in such a way that twisting of the switch tongue in the adjacent position is prevented and at the same time the switch tongue is held down to the desired extent.
  • both the rail foot on the sliding chair and the rail head should be pressed against the stock rail.
  • the lock should also be easy to move, with parts that are firmly connected to the rail or tongue being designed to be as light as possible in order to prevent high acceleration forces.
  • the object is achieved on the one hand essentially in that the vertical force component of the resultant force cuts the rail foot or the pad in the immediate vicinity of the rail foot.
  • the teaching according to the invention ensures that the vertical force component of the resultant forces prevents the switch tongue from tipping over, as a result of which, as in the prior art, there is a gap between the stock rail and the switch tongue.
  • the force resultant should cut the transition area between the rail foot and the web of the switch tongue, which ensures that the components of the force resultant, on the one hand, the switch tongue in their rail foot region and, on the other hand, in their rail head region - namely the contact surface with the stock rail - Cut in such a way that on the one hand the rail foot is pressed onto the sliding chair and on the other hand the rail head is pressed against the stock rail.
  • the component curve of the force vector that is preceded according to the invention is achieved in particular if the distance between the axis and the switch tongue is kept as small as possible.
  • the distance between the axis of rotation and the facing surface of the web of the switch tongue is approximately equal to 0.94 times the height of the switch tongue in this area, the axis running approximately 0.56 times the height of the switch tongue above the sliding chair.
  • the distance can be increased by up to 50 mm or reduced by up to 20 mm.
  • the distance to the sliding chair can vary by ⁇ 20 mm.
  • the measures according to the invention ensure that the switch tongue in the locked position cannot be tilted, that is to say can be rotated, even when a high force is applied, and at the same time a secure hold down on the base, that is to say the sliding chair, is ensured without additional aids.
  • the locking element like the locking clip, starts from a shaft and is displaceable along it, which in turn forms a rigid unit with the switch tongue.
  • an elastic bushing can also be arranged between the section and the shaft, in order to be able to cushion the closure element, that is to say the closure clip.
  • the region of the closure element interacting with the sliding element can be designed as a sliding element such as a sliding head.
  • a possible embodiment is a sliding roller.
  • a section of a switch is shown, in which switch tongues (12), (14) which can be supported on documents such as sliding chairs (11) and which can be pushed back and forth on them, optionally with a associated stock rail (16) or (18) should be locked or opened to this.
  • the clamp closures used for this purpose comprise a closure piece (20) or (22) starting from the stock rail, which has a rectangular opening (24), on the one hand from a push rod (26) or (28) and on the other hand from a section of one Locking clip (30) or (32) is penetrated.
  • the rectangular opening (24) has on the side facing away from the stock rail (16) or (18) an extension formed by a bevel (34) which interacts with a corresponding section (36) of the locking clip (30) when the Turnout tongue (12) locked, that is to rest against the stock rail (16).
  • the area on the slope (34) and the section (36) lying on top of one another can be referred to as the support area (35).
  • the locking clip (30) also has a projection (38) which extends in the direction of the push rod (26) and which then penetrates into a correspondingly adapted recess (40) in the push rod (26) when the switch tongue (12) spaced from the stock rail (16), that is to say to be opened, by pushing the push rod (26) to the right or the push rod (28) to the left.
  • An open position is shown in the right part of FIG. 1.
  • the push rods (26) and (28) have the same geometry and are preferably connected via an insulating piece (42), with adjustability via elongated holes in a known manner in order to be able to adjust the spacing.
  • closure clip (30) or (32) is connected in an articulated manner to a clip receptacle (44) or (46) in the manner described below, only the closure clip (30) being discussed for reasons of clarity.
  • closure clip (32) with the clip receptacle (46) and the other elements has the same construction.
  • the clamp receptacle (44) starts from the rail foot (48) of the switch tongue (12) facing away from the stock rail (16) and has a shaft (50) running above the rail foot (48), which runs over the cheeks of the clamp receptacle (46 ) is held.
  • the shaft (50) forms the axis of rotation (52) for the locking clip (30), ie it lies above the rail foot (48) of the switch tongue (12).
  • the locking clip (30) has an L-shape, the short leg (54) surrounding the shaft (50) with a section (56). There is also an elastic bushing (58) between the section (56) and the shaft (50).
  • the length dimension of the section (56) and the bushing (58) is less than the free length of the shaft (50), so that the locking clip (30) along the shaft (50) can hike.
  • the elastic bushing (58) also provides a cushioning of the locking clip (30).
  • the long section (60) of the locking clip (30), which runs approximately parallel to the rail feet of the stock rail (16) or the switch tongue (12), has the oblique section (36) required for the fixing. and the projection (38).
  • the section (38) of the locking clip (30) guided along the push rod (26) can be designed as a sliding head or roller (39) in order to achieve smooth operation. This can at the same time achieve the advantage that the amount of lubricant to be used is reduced.
  • FIG. 6 shows the force vector causing the locking or the resultant force (62) and its components (64) and (66) again to illustrate the teaching according to the invention.
  • the force vector (62) runs between the axis (52) about which the locking clip (30) can be pivoted and the support area (35) between the geometrically adapted bevels (34) and (36) of the locking piece (20) and the locking clip (30).
  • the size and direction of the vector (62) between the axis (52) and the support region (35) are selected such that the vertical force component (64) intersects or at least runs in the vicinity of the base (68) of the switch tongue (12) this ensures that the switch tongue (12) cannot tip regardless of the size of the force introduced via the locking clip (30).
  • the axis (52) must be brought close to the switch tongue.
  • the distance B of the axis (52) from the facing surface (74) of the web (76) of the switch tongue (12) is preferably 0.94 times the height of the switch tongue (12).
  • the axis (52) is furthermore at a distance H above the surface of the base (11), the distance H preferably corresponding to 0.56 times the distance B.
  • the distance can be increased by up to 50 mm or reduced by up to 20 mm.
  • the distance to the sliding chair can vary by ⁇ 20 mm.
