Definitions

  • the invention relates to a ladder lift, in particular for furniture transportation, with a ladder which can be plugged together from several parts, on the side cheeks of which a lifting carriage having a supporting frame and a loading platform carried by the latter is guided, which can be moved on the ladder by means of a rope driven by a cable winch, wherein the support frame for the horizontal positioning of the loading platform has a horizontal pivot axis and length-adjustable supports.
  • the loading platform is arranged on a frame, one end of which is pivotable about a pivot axis provided at the upper end of the lifting carriage.
  • the length-adjustable supports engage, which in turn are supported on the lower end of the lifting carriage.
  • the invention has for its object to provide a ladder lift, in particular for furniture transportation, of the type mentioned, with which longer pieces of furniture can also be easily transported and removed comfortably and safely at the upper end of the ladder.
  • the support frame has on its upper side two horizontally adjustable guide rails extending transversely to the plane of movement of the lifting carriage, that a carriage can be moved on the guide rails, which carries the loading platform rotatable about a vertical axis and that two with height-adjustable support feet provided, horizontally adjustable extension rails are provided, which can either be attached to the upper end of the ladder or which are connected to the guide rails of the support frame by means of horizontal swivel axes and are aligned with the guide rails in the uppermost position of the lifting carriage, with spacers being provided at the upper end of the ladder with which the ladder is supported on the building.
  • the loading platform can be rotated in the uppermost position of the lifting carriage, it is necessary for the carriage carrying the loading platform to be at a sufficient distance from the building wall.
  • This distance can be achieved in different ways.
  • Another variant consists in making the guide rails so long that the carriage, as soon as the lifting carriage has reached its uppermost position, can be moved outwards on the guide rails perpendicular to the building wall. As a result, the loading platform is at a greater distance from the outer wall of the building and can be rotated freely.
  • 1 denotes a ladder which can be plugged together and screwed together from several parts.
  • a lifting carriage 2 is guided on the side cheeks of this ladder.
  • the lifting carriage 2 can be moved on the ladder by means of a cable winch (not shown) arranged at the lower end of the ladder and a cable 4 guided over a deflection roller 3.
  • a support frame, generally designated 5, Arranged on the lifting slide 2 is a support frame, generally designated 5, which essentially consists of a frame 5a and supports 5b variable in length.
  • the frame 5a is mounted at the upper end of the lifting carriage 2 so as to be pivotable about a horizontal pivot axis 6 which runs transversely to the direction of movement of the lifting carriage.
  • the supports 5b which in turn are supported on the lower end of the lifting slide 2, act on the end of the frame 5a facing away from the conductor 1.
  • the support frame 5 has on its top, i.e. on its frame 5a two guide rails 7 which extend transversely to the plane of movement of the lifting carriage 2 and which extend beyond the supporting frame 5 on the side facing away from the lifting carriage 2.
  • the length L of the guide rails is greater than their mutual distance A, which corresponds approximately to the width of the conductor 1.
  • a carriage 8 can be moved on the guide rails 7.
  • This carriage 8 carries the loading platform 10, which is rotatable about a vertical axis 9.
  • the loading platform 10 is expediently rectangular in plan.
  • extension rails 11 are provided, which can be attached to the upper end of the conductor 1. These extension rails 11 are provided at one end 11a with height-adjustable support feet 12. At the other end 11b, the extension rails 11 expediently have two short support arms 13 which are supported on the ladder 1. So that the carriage 8 can be moved from the guide rails 7 into the extension rails 11, it is important that these rails are aligned with one another in the uppermost position of the lifting carriage 2.
  • the support point 14 of the support arms 13 on the pus 1 is advantageously arranged on a parallel P to the ladder 1 passing through the pivot axis 6.
  • the support point 14 of the support arms 13 is expediently formed by a plug pin 14 provided for each support arm.
  • This socket pin 14 can be inserted on the one hand into a transverse bore at the upper end of the conductor and on the other hand into a transverse bore at the lower end of each support arm 13.
  • two spacers 16 are provided at the upper end of the ladder 1, with which the ladder (1) is supported on the building.
  • the loading platform is expediently provided with hinged and optionally also removable side walls 15.
  • the loading platform 10 When furniture is being transported, the loading platform 10 is pivoted into the position shown in FIG. 2, in which its long side extends parallel to the outer wall of the building. In this position, the loading platform 10 is loaded with pieces of furniture and then the sliding carriage 2 is moved to the upper end of the ladder 1.
  • the guide rails 7 of the support frame 5 then assume the position shown in broken lines in FIG. 1, in which they are aligned with the extension rails 11 supported on the one hand on the ladder 1 and on the other hand inside the building.
  • the window openings are too narrow, especially when longer pieces of furniture protrude beyond the broad sides of the loading platform.
  • the pieces of furniture with their greatest longitudinal extent are transported parallel to the outer wall of the building as described.
  • the carriage 8 can now be moved outwards on the guide rails 7, so that the pivot axis 9 reaches the dot-dash position.
  • the pivot axis 9 has a greater distance from the outer wall of the building, and the loading platform 10 can now be pivoted so that its broad side runs parallel to the outer wall of the building.
  • the loading platform can now also be moved through the narrow window openings with the pieces of furniture arranged on it.
  • the spacer 16 ' is designed to be somewhat longer, as a result of which the guide rails 7 can be kept shorter and do not need to protrude beyond the supporting frame 5.
  • the extension rails 11 ' are connected to horizontal axes 17 which extend transversely to the direction of movement of the lifting carriage 2 and are folded up.
  • the extension rails 11 ' also have height-adjustable support feet 12 which can be supported on the spacers 16'. By means of these support feet 12 ', the folded-down extension rails 11' can be adjusted horizontally.
  • the length of the spacers 16 ′ corresponds approximately to the width of the conductor 1.
  • the spacers 16 are expediently pivotable about horizontal axes 18 extending transversely to the direction of movement of the lifting carriage 2 and can be fixed by means of the length-adjustable struts 19.
  • a piece of furniture of greater length is transported exactly as described above in such a way that the piece of furniture with its greatest longitudinal extent is transported parallel to the building wall until the lifting carriage has reached its uppermost position.
  • the extension rails 11 ' are folded up into their dot-dash position.
  • the extension rails 11 ' can be folded down and are then supported with their support feet 12 'on the spacers 16'. They are now in alignment with the guide rails 7. Thanks to the greater length of the spacers 16 ', in this exemplary embodiment the loading platform, which is shown in two different rotary positions in FIG. 5, can be pivoted freely (in FIG. 4, the loading platform has been omitted for reasons of clarity ).
  • the loading platform with the piece of furniture arranged thereon can be moved through the window opening and removed from the loading platform.
