Definitions

  • the invention relates to a lifting device, in particular for beds, with two vertical guide columns in the form of longitudinally slotted hollow profiles, threaded spindles mounted in the interior of the guide columns, and through the longitudinal slot of each guide column connected with spindle nuts, lifting and lowering load-bearing members.
  • a lifting device of the type mentioned (but for lifting vehicles in automobile workshops) is known from US-A 1,497,046.
  • the two threaded spindles can be driven together by hand via bevel gear and an intermediate shaft.
  • Two vehicle wheel sensors, each connected to a spindle nut, are located between the two columns.
  • Such a device is completely unsuitable for lifting and lowering beds and similar loads.
  • the object of the present invention is to provide a lifting device which avoids the above-mentioned shortcomings of known devices and which is particularly easy to assemble and permits practically complete, free use of the space under the raised bed.
  • the lifting device according to the invention which meets these requirements, is characterized in that the guide columns are connected by means of upper and lower cross connectors to form a flat, rigid frame designed for wall mounting, and that two threaded nuts run at a distance on each threaded spindle, on which a jib protruding from the plane of the frame is attached.
  • the lifting device designed in this way can be attached "flat" to the wall of the room with the flat frame placed on the floor, with the bed being held by the two arms with the long sides parallel to the wall.
  • the bed is therefore completely free on three sides. Under the bed are only the two outriggers, which are lifted together with the bed.
  • the lifting device according to the invention can also accommodate other loads instead of a bed, such as bulky play equipment in the living area such as model railroad systems, etc .; but commercial applications are also conceivable, such as the creation of height-adjustable work surfaces for assembly work or the like.
  • the lifting device shown has a load-bearing structure on a flat, rigid frame, consisting of two vertical guide columns 10, which are connected at the top and bottom by a cross connector 12 (axes 13 of connecting screws in the cross section of the column 10 shown in Fig. 4).
  • Fastening tabs or brackets 14 are attached to both cross connectors 12 (and / or to the guide columns 10). With the help of these fastening elements, the lifting device, placed on the floor, can easily be mounted on a room wall 6 (FIG. 2).
  • Each of the guide columns 10 is expediently formed by a square hollow profile with a longitudinal slot 11; they are preferably produced as an extruded profile from a light metal alloy, so that post-processing is not necessary.
  • Each of the guide columns 10 is assigned a threaded spindle 20 which runs parallel to the column inside the profile and is mounted in a bearing 21 on the frame or in each case in the upper and lower cross connector. Run on each threaded spindle 20 two spaced nuts 22, which are guided on the associated guide column 10, in the present case on the inner walls of the square hollow profile.
  • the nuts 22 are expediently made of an abrasion-resistant plastic; With regard to abrasion and sliding properties compared to the guide column 10 and a threaded spindle 20 with a rolled thread, a low-pressure polyethylene mixture (trade name "Polydur”) is particularly suitable.
  • the longitudinal slots 11 of both guide columns 10 face each other, and the nuts 22 protrude somewhat from the profile 10 through the slot in question (FIG. 4).
  • an outrigger projecting from the plane of the frame is attached for the load bearing.
  • the cantilevers are designed as essentially flat plates 24, with the upper edge of which is connected to a square tube 25.
  • the arms 24 can be raised and lowered in the same direction along the associated guide columns 10; in Fig. 1, the two arms are shown near their lower end position.
  • Holding members 26 are mounted on the upper edge of each boom to receive the frame or frame 8 of a bed 7 (Fig. 2).
  • the holding members 26 can be slidably attached to the outriggers, or the outriggers can be adjustable in length (extendable) in order to allow adaptation to bed frames 8 of different widths.
  • a support leg 27 can be attached, which can be folded up when the boom is raised and thereby comes to rest under the square tube 25 (not shown in FIG. 1).
  • a common drive motor 15 is provided, which, for. B. is mounted on the upper cross connector 12.
  • the drive connection from the pinion 17 of the motor to a pinion 19 at the upper end of each spindle 20 takes place by means of a toothed belt 16, which via the said pinion and guide rollers 18 and one Tension roller 18 'rotates. Thanks to this drive of the spindles with the same direction of rotation, identical spindles and nuts with right-hand thread can be used on both sides.
  • the upper and lower end positions of the brackets 24 are fixed by means of limit switches 33 mounted on the guide columns 10, which interact with the nuts 22.
  • a cover for the longitudinal slot 11 on the associated guide column 10 is also connected to each boom; it is a band 31 formed into a loop, which is guided over lower and upper deflection rollers 32 and moves with the lifting and lowering of the booms.
  • the lifting device described can be transported very easily as a unit, only the two arms not yet being screwed to the nuts 22.
  • the flat frame can be easily attached to a room wall, and then the two brackets are installed. After establishing the electrical connection for the drive motor 15, the device is ready for use. So that the booms cannot be raised or lowered unauthorized or willfully (e.g. by children), it is advantageous to provide a motor switch with key lock or security by entering a code number or the like; Remote control using infrared control or the like is also conceivable.
  • the construction shown with two nuts 22 guided on the columns 10 enables very effective load absorption and guidance of the loaded cantilevers on the guide columns.
  • the height spacing of the two nuts on the spindles can be selected as required in order to be able to fasten boom plates of different heights.
  • Commercially available beds can be used with the lifting device, and no changes or assembly work are required on the frame.
  • the bed is made with one long side parallel to the wall or frame of the two outriggers, leaving the three remaining sides of the bed completely free. Above all, it is advantageous that when the bed is raised, the space underneath, apart from the flat frame mounted on the wall, is completely freely accessible and usable, as can be seen above all from FIG. 2.
  • the load suspension via self-locking nuts on spindles also offers a high degree of safety, in contrast to, for example, load suspension on cables, chains or the like.
  • the entire frame can be hidden behind a cladding, for example designed as a wall unit (not shown), in which only two narrow slots are to be provided for the implementation of the two plate-shaped brackets.
