  • the lifting device is provided with a self-locking drive and designed and arranged such that it engages the bed frame on said end face.
  • the lifting device has at least one electric motor for driving self-locking lifting spindles, wherein for an emergency operation, a crank is provided which can be coupled to the lifting spindles and this meshes when the crank is rotated.
  • EP-B1-0 418 415 describes an overload protection device by means of which a deformation of the bed frame, as well as the guide device, is prevented when a predetermined load of the bed frame is exceeded.
  • the floating bed described in EP-B1-0 418 415 is very space-saving and reliable.
  • the lifting device is arranged in the region of the guide device, practically no living space is required, when the suspended bed is raised below the ceiling.
  • the self-locking drive allows the floating bed to be stored safely and vibration-free in any vertical position.
  • a disadvantage of the floating bed according to EP-B1-0 418 415 is that triggering of the overload protection device can lead to injuries of a floating bed user and in particular an intensive floating bed use leads to material fatigue of this overload protection device, which can lead to unmotivated triggering the same.
  • the present invention seeks to provide a lift bed having improved safety devices.
  • the guide device 4 comprises a vertical guide rail 5, to which a carriage 6, which is rigidly connected to the bed frame 2, can be moved vertically up and down.

  • the sprocket 11 may be attached to the upper end of the guide rail and thus assume the function of the guide roller 10.
  • the pull chain 9 can be replaced by a toothed belt, wherein the sprocket 11 is formed by a corresponding drive wheel for driving the toothed belt.
  • the lift bed 1 comprises two vertical guide means 4, which are arranged parallel to each other at a distance of a bed frame width and are preferably fastened to a load-bearing wall of the room by means of suitable screws.
  • the guide means 4 are arranged with respect to the bed frame width such that the rollers 7, 8 of the carriage 6 to the sides have minimal play.
  • the carriages 6 each have, on the side facing the corresponding guide rail 5, at least one guide F, which leads to jamming in the case of a lateral tilting of the bed frame 2.
  • the guide F is formed as a plastic block and consists of a strength carrier, a binder and fillers of various kinds, which are for the appropriate adjustment of the coefficient of friction of the guide F of importance.
  • a strength carrier e.g. Asbestos fiber, asbestos fabric or steel wool can be used.

  • the plastic block is preferably formed as a cuboid with a base side of a few centimeters.
  • the jamming can be enhanced or effected in particular by a suitable forming of the guide rail 5, which according to a preferred embodiment of the present invention can be toothed, so that when the bed frame 2 is tilted the carriages 6 are each held in corresponding, tooth-shaped edges of the associated guide rails 5 ". engage ".
  • the bed frame 2 is designed such that with respect to the bed frame width results in an uneven weight distribution.
  • An advantage of such an embodiment is that the bed frame 2 is tilted and jammed in an uncontrolled movement up or down, which leads directly to a standstill of the bed frame 2.
  • the bed frame 2 so to speak "crashes" due to a breakage of one or both pull chains 9, the corresponding guides tilt laterally and the bed frame 2 is blocked, so that a crash can be avoided.
  • Jamming and jamming is also effected in the event that a misalignment of the tension chains 9 occurs and the load to be lifted or lowered thus predominantly on a pull chain 9 or a side of the bed frame 2 loads.
  • Such tilting and jamming is particularly advantageous in the event that the lift bed 1 according to the invention is used improperly, for example by raising or lowering the bed frame 2 with persons on the bed.

  • the endless belt which is carried along with the bed frame 2 up or down, conceals the corresponding opening
  • each endless belt can be guided laterally, so that neither an insight into the corresponding guide device 4, nor a "Hineinprehensi" is possible.
  • An advantage of such an endless belt is that a user can not grasp, for example, when lifting or lowering the bed frame 2 into the interior of a guide device 4, so that injuries can be prevented by improper use.
  • each endless belt can also be connected to the corresponding counterweight 12.
  • the guide rails 5 of the guide means 4 are preferably each formed as a T-beam, which has a length corresponding to the room height. At the upper and lower ends of the T-beam is substantially perpendicular to the side of the T-beam, which opens to the bed frame 2 back, attached a top plate 13 and a foot plate, not shown, which extend along a load-bearing floor or a load-bearing floor , The attached to the T-beam head plate 13 and base plate preferably each have a length of 30 cm.
  • each guide rail 5 with such a foot part ensures that a tipping over of the guide rail 5 in the room is almost impossible, provided that the guide rail 5 is not fixed, because by the resting of the bending-secure foot part lying parallel to the bottom wall edge axis of rotation is parallel to Moved front side of the foot part.
  • the guide rail 5, which extends to the ceiling no longer tilt in the room, since the top plate 13 of the guide rail 5 is pressed when tilting against the ceiling by moving the axis of rotation to the front of the foot part.

  • a carriage 6 is formed, each carriage 6 via a pull chain 9, each via a guide roller 10 and / or a sprocket 11 with a counterweight 12 is connected.
  • the two sprockets 11 are preferably rigidly coupled together via a coupling rod to ensure a synchronous rotation of the two sprockets 11.
  • the lift bed 1 is in a so-called night mode, i. the bed frame 2 is near the ground.

  • the bed frame 2 means the carriage 6 along the guide rails 5 is moved vertically upwards.
  • the sprockets 11 or the connecting rod in the night mode can be preferably blocked.
  • the sprockets 11 are released and rotated so that the bed frame 2 moves up while the counterweights 12 move vertically downwards.
  • the counterweights 12 are preferably designed such that the sum of their masses is greater than the mass of the bed frame 2, so that when releasing the sprockets 11 in the event that the lift bed 1 is in night mode, an upward movement of the bed frame 2 thereby arises that the sum of the gravitational forces acting on the counterweights 12 outweighs the gravity that engages the bed frame 2. Thus, it takes no effort, for example, by a user of the lift bed 1 to move the bed frame 2 from the night into the day mode. In order to move the bed frame 2 from the day mode to the night mode, an external force must act on the bed frame 2 or counterweights 12 so that the above-described balance of forces changes in favor of the bed frame 2, causing downward movement of the bed frame 2 can.

This is done by turning the sprockets 11 so that forces are exerted on the carriage 6 via the tension chains 9, resulting in the respectively desired movement.
  • the sprockets 11 In order for a possible tilting of the carriage 6 on the guide rails 5 is avoided during an upward or downward movement of the bed frame 2, the sprockets 11 must be synchronized so that both carriages 6 are moved simultaneously by identical distances up or down. This synchronization of the sprockets 11 takes place by means of a coupling rod 16, via which both sprockets are rigidly coupled together. A rotation of the coupling rod 16 thus causes a simultaneous or synchronous rotation of the sprockets 11th
