Definitions
- the invention relates to a device for locking a switch tongue with a stock rail comprising at least one locking piece starting from the stock rail and an indirectly or directly articulated connection with the switch tongue and penetrating the locking piece, which can be supported or locked via support and roller elements.
- the invention relates to a device for locking a switch tongue with a stock rail comprising a closure piece originating from the stock rail and a closure clip which is connected directly or indirectly to the switch tongue and penetrates the closure piece, and a closure clip which penetrates the closure clip and the closure clip Unlocking or locking of the switch tongue, sliding element mounted on a support such as a rod, the locking clip being in contact with a locked surface directly or indirectly from the locking piece when the switch tongue is locked.
- a corresponding soft clip can be found in EP 0 455 182 A2.
- the resultant force running between the axis of rotation of the locking clip and the support surface intersects the transition area of the rail foot and web of the switch tongue. Furthermore, the vertical force component runs inside or in the immediate vicinity of the rail foot, so that the switch tongue cannot tilt in the locked position. In the locked position, the locking clip is clamped between a push rod and a support surface, so that considerable friction forces have to be overcome when unlocking, even if the locking clip should be supported by a roller element on the push rod.
- EP 0 455 153 A2 proposes that the switch tongue be held down on the base only in the locked and open position, whereas between these positions there is a spacing to the base.
- the locking clip is supported on a stationary support, along which a push rod is displaceable in such a way that rollers of the locking clip are fixed in the locked and open position in receptacles formed between the support and the push rod and during the displacement of sections of the Push rod can be captured and taken away.
- the present invention is based on the object of developing a device of the type mentioned at the outset in such a way that the switch tongue can be locked or opened using structurally simple measures, with ease of movement resulting in a reduction in maintenance. It should also be ensured that the locked switch tongue cannot be unlocked even if the sliding element of the locking clip is no longer properly gripped or, if necessary, released from it. Finally, there must be the possibility of spacing the switch tongue in the unlocked position from the base of the sliding chair. Optimal storage should also be guaranteed.
- the object is essentially achieved in that at least one of the support elements is elastically supported in such a way that it is soft under static load and hard under dynamic load.
- all of the support elements, such as roller element, starting from the closure clip are supported according to the invention.
- the elements which are soft under static load and hard under dynamic load do not originate from the locking clip, but are supported on corresponding roller elements which e.g. can be arranged on the closure piece or a push rod.
- the closure clip rests against a support surface designed as a curved segment via a (first) roller element, and that a second roller element, offset in the direction of the switch tongue, extends from the closure clip and from a horizontally extending section and an angled portion thereof and the guide having the section facing away from the switch tongue is accommodated, the second roller element being located in the horizontally running section of the guide when the switch tongue is locked and in the angled section when the position is unlocked.
- the curve segment in the end region facing the sliding element has a curvature deviating from the radius of the first roller element such that if there is no controlled vertical force component in the locking clip first role element remains in the curve segment.
- the first roller element must overcome a dead center at the end of the curve segment so that the switch tongue can be unlocked.
- the first roller element is elastically supported.
- a guide path for the first roller element runs along the displacement path of the sliding element at least above the angled section of the guide such that the second Roller element remains in the angled section.
- the clear distance between the guide track and the apex of the first roller element in the case of the second roller element present in the angled section is smaller than the effective length of the angled section for the second roller element.
- the locking clip can be displaced from the push rod without canting, a further development of the invention provides that the locking clip comprises two angle levers running parallel to one another and supporting the first and second roller elements, between which the sliding element runs.
- an inventive development of the invention is characterized in that the sliding element facing away from the stock rail has a projecting section or shoulder, with which, when the switch is unlocked, the locking clip is supported on the base-side support in the form of preferably a further (third) roller element, as a result of which there is a spacing between the switch tongue foot and the base like a sliding chair. Consequently, structurally simple measures ensure that the switch tongue can be spaced from the base in the unlocked position.
- the section or shoulder projecting on the bottom should have a length such that the switch tongue rests on the base in the locked or open position, but is spaced from the base during the displacement path.
- FIG. 1 is a sectional view through a switch with clamp closure and locked and clamped switch tongue
- FIG. 3 shows the clamp closure according to FIG. 1 with the switch tongue unlocked and not clamped
- FIG. 4 the clamp closure according to FIG. 1 with the switch tongue fully unlocked
- FIG. 6 the clamp closure of FIG. 1 with the switch tongue
- a starting piece (14) extends from the stock rail (10), which is interspersed on the one hand by a push rod (16) and on the other hand by a locking clip (18), preferably in the form of one of two angle levers running parallel to one another, between which the push rod (16) runs.
- the locking clip (18) is based on a clip receptacle (20) and is rotatably mounted in it 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).
- a support for a first roller element (28) designed as a curved segment (26) extends from the closure piece (14).
- the roller element (28) itself is arranged at the free end of an angled leg (30) of the locking clip (18).
- the locking clip or the angle lever (18) have approximately a U-shape with legs (30) and (32) of different lengths, of which the longer leg (32) rotatably extends from the bracket receptacle (20) and the shorter leg (30) mentioned the first roller element (28) carries.
- a second roller element (36) is also elastically mounted, which extends within an angled guide (38) of the push rod (16).
- the push rod (16) itself is supported on a third roller element (40) in the bottom region of the closure piece (14).
- angled guide (38) consists of an essentially horizontal section (46) and a section (48) describing an obtuse angle, which section is in the direction of the underside (50) of the push rod (16) extends.
- a shoulder (52) Protruding from the underside (50) of the push rod (16) is a shoulder (52), the length of which is less than the distance of the displacement path of the switch tongue (12) between the locked and open positions.
- Fig. 1 the switch is shown with a locked switch tongue (12) resting against a stock rail (10).
- the first roller element (28) starting from the angle lever (18) bears against the curve segment (26).
- the connecting line between the support thus formed and the axis (22) of the angle lever (18) intersects the transition area between the web and the foot of the stock rail (10). This ensures that the switch tongue (12) bears securely against the stock rail (10).
- the vertical force component passing through the axis (22) runs directly in the region of the foot (24) of the switch tongue (12), it is also ensured that the switch tongue (12) cannot tip over.
- the second roller element (36) In the locked position, the second roller element (36) is also located in the horizontally extending section (46) of the guide (38). If the switch tongue (12) is to be unlocked, the push rod (16) must be moved in the direction of the arrow (58). The roller element (28) moves along the curve segment (26). At the same time, the second roller element (36) reaches the transition area between the horizontal section (46) of the guide (38) and the angled section (48).
- the roller element (28) In order to carry out a complete unlocking (FIG. 3), however, the roller element (28), which is mounted elastically, must overcome a so-called dead center, which is generated by the curve segment (26) in that the one facing the push rod (16) End region (60) is not adapted to the radius of the roller element (28). Rather, the distance in the end region (60) and the axis of rotation (22) is greater than the distance between the axis of rotation (22) and the axis of rotation (62) of the roller element (28) minus its radius.
- the dead center is overcome, however, by forcing the second roller element (38) along the angled section (48), that is to say its inclined wall in the direction of the floor, when the push rod (16) is moved further in the direction of the arrow (58) (64) of section (48).
- a vertical force component is introduced onto the angle lever (18) to such an extent that the roller element (28) can overcome the dead center (60).
- this is a continuous recess in the push rod (16), which extends partially in a section (70) projecting towards the stock rail (10).
- the roller elements (28), (36), (40) and (42) are to be supported elastically in such a way that a soft bearing results under static loading and a hard bearing under dynamic loading.
