Definitions

  • a rail-suspended carriage for movable partition walls has a carriage body provided with an axle on which a pair of wheels are mounted which can engage a rail along which the carriage is to travel.
  • Turnable guide rollers are provided, each being adapted to roll along a rail in lateral engagement therewith and each being turnable about a first vertical axis and the latter in turn being pivotable about a second vertical axis paralleling it.
  • a track roller is turnable about another vertical axis laterally offset from and paralleling the first and second axis, and a motion-transmitting arrangement is provided which enforces pivotal movement of the first axis of one guide roller about the second axis thereof in one direction, if the first axis of the other guide roller is pivoted about its second axis in an opposite direction, and vice versa.
  • Another object of the invention is to provide such a rail-suspended carriage which has a single axle and is specially suitable for passing through and around curvatures of minimum radii, without requiring special guides or guide arrangements.
  • a rail-suspended carriage particularly suitable for movable partition walls, which briefly stated comprises a carriage body having an axle, and a pair of wheels mounted on this axle and adapted to engage a rail along which the carriage is to travel.
  • a pair of turnable guide rollers are provided on the carriage body and each adapted to roll along a rail in lateral engagement therewith.
  • the guide rollers are each turnable about a first vertical axis and the latter is in turn pivotable about a second vertical axis paralleling the respective first axis.
  • a track roller is turnable about another vertical axis which is laterally offset from an parallels the first and second axis, and means is provided for pivotal movement of the first axis of one guide roller about the second axis thereof in one direction, in response to pivotal movement of the first axis of the other guide roller about the second axis thereof in an opposite direction, and vice versa.
  • FIG. 1 is a side-elevational view of a carriage according to the present invention
  • FIG. 2 is a view similar to FIG. I but showing the carriage from the opposite side thereof;
  • FIG. 3 is an end view of the carriage
  • FIG. 4 is a top-plan view of the carriage
  • FIG. 5 is a bottom plan view of the carriage.
  • FIGS. 6-10 are respective diagrammatic illustrations showing the carriage in different positions as it passes through a small-radius curve of a guide rail.
  • reference numeral 1 identifies the carriage body which is provided with a guide roller 2 located centrally thereof and at the lower end, the guide roller 2 being turnable about a vertical axis.
  • An axle 3 passes through the body I and carries the wheels 4 and 5, and of course it will be understood that instead of a single axle 3 it will be possible to use two stub axles.
  • a projection 12 in which there is journalled a track roller I3 for turnable movement about a vertical axis 14 which is spaced at such a distance from the rollers 10 and II that between the latter and the track roller 113 a rail 15 illustrated in chain lines in FIG. 3 can be accommodated with some play.
  • the rail 15 has the wheel 4 rolling on it, but serves only as a support rail for the wheel 5.
  • the track roller 13 is offset on a different level with respect to the rollers 10 and 11, so that it not only engates the guide rail 16 (also shown in chain lines in FIG.
  • the illustrated embodiment provides two springs 19 and 20 which may advantageously be mounted on the axes 6 and 7 and which permanently tend to pivot the brackets 8 and 9 in the direction of the arrows x and y, respectively, towards the track roller 13 (see FIG. 5), thereby urging the rollers 10 and II against the rail I5.
  • a mounting member here configured as a carrying rod 21, by means of which a component (for instance a movable partition wall) can be mounted on the carriage body 1.
  • the carriage (of which the rollers 10 and 11, the roller 2, the roller 3 and the diagrammatically illustrated wheels 4 and with their axle 3 have been shown) moves in the direction of the arrow 2 on a straight portion of the two rails 15 and 16 towards the 90-degree curve.
  • FIG. 6 shows the roller 11 entering the curve, as a result of which the roller 11 and the roller are slightly pivoted towards the left out of the direction of advancement, as a result of which a slight inclination of the axle 3 for the wheels 4 and 5 relative to the rails and I6 is obtained at this point.
  • FIGS. 8 and 9 show that as the carriage increasingly moves into the curve, this inclination of the axle 3 and the wheels 4 and 5 becomes more pronounced
  • FIG. 10 shows that the carriage has passed through half of the curve and that due to the cooperation of the rollers 10 and 11 and the track roller 3 the inclination of the axle 3 for the wheels .4 and 5 coincides with the 45-degree radius of the curve.
  • the rail 16 may be absent over a short distance, this means that the wheel 5 will have no support.
  • the one-sided load resulting from this is taken up by the track roller 13 in conjunction with the guide roller 2, in that the roller 13 is offset vertically with reference to the roller 2 and can laterally engage the rail 5.
  • the lateral support of the track roller 13 prevents the carriage from jumping its rails.
  • the carriage can move through curves of minimum radius. Furthermore, the carriage is so well guided that rather high loads can be supported from it without having to make the carriage undesirably large.
  • the carriage is also capable of moving over and through rail junctions without having to fear that the carriage might tilt or become jammed due to the fact that only one of its wheels 4, 5 is in contact with a rail sometimes.
  • wear of the components of the novel carriage is low, the turning of the axle 3 begins before the carriage itself has reached the curve, and the inclination of the axle automatically follows the curve as the carriage moves therethrough.
  • a rail-suspended carriage particularly for movable partition walls, comprising a carriage body having an axle; a pair of wheels mounted on said axle and adapted to engage a rail along which said carriage is to travel; a pair of turnable guide rollers on said carriage body and each adapted to roll along a rail in lateral engagement therewith, said guide rollers each being turnable about a first vertical axis which is in turn being pivotable about a second vertical axis paralleling the respective first axis; a track roller turnable about another vertical axis which is laterally offset from and parallels said first and second axes; and means for causing pivotal movement of the first axis of one guide roller about the second axis thereof in one direction, in response to pivotal movement of the first axis of the other guide roller about the second axis thereof in an opposite direction, and vice versa.
  • said biasing means comprises at least one spring.
  • a carriage as defined in claim 1, wherein said means comprises meshing gears connecting said second axes with one another.
