Definitions

  • the invention relates to a retractable switch machine, with a Push rod that adjusts switch tongues, as well as with a between one Drive unit and the push rod arranged coupling device, which one in the engaged state spring-loaded into a recess of the push rod engaging holding roller which move against the spring force in one direction when the switch is opened moved out of the recess.
  • the object of the present invention is to provide a point machine improve the type mentioned so that the disadvantages mentioned known arrangements can be avoided and that in particular on simple
  • the coupling device between the drive unit and the push rod equally safe function can be constructed more space-saving.
  • This object is achieved according to the invention in a point machine mentioned type in that two substantially symmetrical with respect counter-rollers arranged in the direction of movement of the holding roller are provided, which is essentially perpendicular to the direction of movement of the holding roller slidably supported and by at least one retaining spring in the direction of the system the holding roller is loaded. So that can be done in a very simple way existing need, the holding spring loading the holding roller in the direction of movement the holding roller - normally perpendicular to the push rod protruding - to be arranged, bypassed. There is extensive Freedom in the arrangement of this retaining spring, since this spring is now only acts indirectly on the holding roller via the counter rollers, which is a very compact construction of the coupling device with essentially the same Function can be achieved as before.
  • the retaining spring is in a further embodiment of the invention - as well previously mostly - designed as a helical compression spring, but can now be used in be arranged essentially parallel to the push rod, which with regard to the space-saving construction mentioned is optimal.
  • the holding roller at least on one side in a housing of the coupling device Sliding block guided perpendicular to the push rod, whereby the two counter rollers on in the housing of the coupling device parallel to Push rod displaceable counter roller housings are arranged, which over the retaining spring are loaded against each other.
  • FIG. 1 shows a partial cross section through a Point machine according to the invention in the area of the coupling device between not shown drive unit and push rod and Fig. 2 shows a partial top view of the arrangement of FIG. 1 from above.
  • Push rod 1 is movable in the direction of the double arrow 2, the here Actual drive unit, not shown, via a coupling device 3 acts on the push rod 1.
  • the end position of the push rod 1 is on the housing 4 of the coupling device 3 spring-loaded left retaining bar 5 in a detent 6 on the housing base 7 locked, with which the associated end position of the over Push rod 1 operated switch tongues is fixed.
  • a right Denoted locking bar which in turn is spring-loaded on the housing 4 is and in the right end position of the push rod 1 in engagement with a Corresponding not shown on the housing bottom 7 comes.
  • the retaining spring 13 is designed here as a helical compression spring and in arranged substantially parallel to the push rod 1, which is a very compact design with safe function of the coupling device 3 results.
  • the only retaining spring 13 is, on the one hand, direct on the counter roller housing 14 and on the other hand via a clamping piece 16 with adjusting screw 17 and transmission bracket 18 - consisting essentially here from the two threaded rods 19 and the head pieces 20 - on the other Counter roller housing 15 supported, which is a deflection in a very simple manner the effect of the spring force on the load on the holding roller 10.
  • the push rod 1 (with the locking bar 5 or 8 held coupling device together with holding roller 10) its depression 9 pressed out of the engagement area of the holding roller 10, what to a retraction of the holding roller 10 against the action of the spring-loaded Counter rollers 12, 12 'leads, which in turn together with the counter roller housings 14, 15 are pushed apart.
  • the push rod 1 is so freely movable relative to the coupling device 3 or to the drive unit, until it is in accordance with the position of the holding roller 10 with the recess 9 in turn comes to a coupling.
  • coil spring Holding spring 13 could of course also suitably two or more, also, for example, springs designed as disc springs or the like, possibly also be arranged on both sides of the holding roller 10 - likewise it would also be possible to have a different angle than the illustration Arrangement of the possibilities of movement of the holding roller 10 and / or counter rollers 12, 12 ', which may require consideration special local conditions is possible.
