Definitions

  • the invention is directed to a device for adjusting and locking the head part of a bed frame with a gas pressure spring which acts in the pivoting direction of the bed frame and can be released via a handle, the lying surface in particular consisting of at least three frame parts pivotably mounted on the bed frame as head part, middle part and foot part, whereby the gas pressure spring is arranged below the head end region of the head part and acts on a pivot lever on an axis of rotation.
  • Such a device is e.g. B. is known from US-A-3 447 170.
  • a bed adjustment by means of two hydraulic drives is disclosed here.
  • the head section can be swung open using a simple, hydraulically actuated swivel lever, as can the foot section with a hydraulic cylinder below a rigid middle bed section.
  • the rigid middle bed section has certain comfort disadvantages.
  • the double hydraulic drive is very complex.
  • Other motorized head part adjustments or mechanical ones via gas pressure springs are also known. These solutions have in common that the motor drive or the gas pressure spring are arranged substantially below the central part of the bed frame and z. B. act on the bed frame pivotally mounted on the pivot point extended beyond the pivot lever (DE-U-77 37 374 and 80 01 323).
  • the object of the invention is to provide a solution which makes it possible to open and lock the head part of a multi-part bed frame with simple means.
  • the axis of rotation is firmly connected to a lower scissor lever of a two-lever scissor joint, the free end of the other upper scissor lever being rotatably arranged on the head part and on the stationary part of the bed frame for locking the head part in its lowered position a catch is provided.
  • a scissor joint which can be pivoted by a gas pressure spring in any desired position. If the handle is no longer actuated, the gas pressure spring remains in the position it has assumed.
  • the scissor joint offers an extremely simple structural design. It is torsion-proof and enables particularly favorable lever lengths.
  • the mechanical lock of the head part in the lowered position makes it possible to dispense with special locking devices that are intended to prevent z. B. when sitting on the middle part of the bed frame, the articulation area between the head part and the middle part lowers and thus the head part swings up unintentionally. Such a catch is structurally simple and very reliable to operate.
  • the invention provides that the axis going through the articulation point of the gas pressure spring on the swivel lever is arranged in the lowered position of the head part approximately in the middle between the axis of rotation on the one hand and the axis of rotation defined by the articulation points of the upper swivel lever on the other hand on the head part.
  • the invention provides that at the same time the catch can be moved by the locking into a position releasing the head part from the actuating handle of the gas pressure spring. This measure also simplifies the design effort and ensures functional reliability of the elements concerned.
  • the handle can be expedient to design the handle as a Bowden cable, which the invention also provides.
  • the invention provides that the catch is formed on a locking lever with a pivot axis on the stationary part of the bed frame and the actuation of the release nipple of the gas pressure spring is carried out via a release lever, which in turn is also on a stationary Element of the bed frame is pivotally mounted, the locking lever and the release lever can be moved synchronously by actuating the Bowden cable.
  • the distance z. B. is very precisely adjustable via a spacer bushing.
  • the invention is not limited to this trigger mechanism. Others can have the same effect here de funds may be provided, such as. B. an electromagnetic drive of the corresponding lever u. Like. more.
  • a measure known per se is provided according to the invention, namely that the articulation between the head part on the one hand and the lowerable middle part of the bed frame on the other hand takes place via a cross-country ski run.
  • This design makes it possible for the middle part to be arranged at the other end in a rotating fitting on the bed frame, so that the foot part itself can be provided with a conventional adjusting device, which is not particularly important in the context of this invention.
  • pivotable frame parts In a frame of a bed, a bed or the like, generally designated 1, at least three pivotable frame parts are arranged about axes 2 and 3, namely a two-part head part 4, a middle part 5 and a foot part 6.
  • the spring strips are designated 7.
  • the type of female connectors and their special mounting on the individual frame parts are not important here.
  • the pivot axes 2 and 3 are each stationary, i. H. they do not change their position in relation to frame 1.
  • lateral cheeks 8 are fastened to the frame 1 and rotatably carry a pivot axis 9 shown here rectangularly as well as a connecting tube 20.
  • a pivot lever 10 is welded to the pivot axis 9, as are two lower scissor levers 11 on the edge, of which only one scissor lever is shown in the figure.
  • the free end of the scissors lever 11 forms the scissors joint 12, on which an upper scissor lever 13 is pivotally arranged, the free end of which is in turn pivoted on the frame 14 of the head part 4.
  • the axis defined by the articulation is denoted by 15.
  • the connecting tube 20 carries a pivot bearing, generally designated 16, for one end 17 of an actuatable gas pressure spring 18, the other end 19 of which is rotatably arranged on the pivot lever 10.
  • the axis defined by the articulation point of the gas pressure spring 18 with the pivot lever 10 is designated by 21 in FIG.
  • the geometry is chosen so that this axis 21 is arranged approximately in the middle between the axes 9 and 15, as can be seen in particular from FIG. 3.
  • One free end 17 of the gas pressure spring 18 is provided with a release nipple 22 with which the gas cartridge of the gas pressure spring 18 can be put into operation when the nipple 22 is pressed.
  • the nipple 22 is actuated via a handle 23 which is designed as a Bowden cable, the Bowden cable 23 pivoting a release lever 24 from the position shown in FIG. 4 to the right for actuating the release nipple 22. If the Bowden cable is not actuated, the lever 24 pivots back into the position shown in FIG. 4. The actuating nipple 22 then locks the gas pressure spring 18 in the assumed position, so that the head part 4 remains in this position.
  • a detent 25 is provided on the detent lever 26 at the head end.
  • the detent lever 26 is connected via a fitting part 27 to a stationary frame part 28 of the frame 1.
  • the detent lever 26 is also actuated via the Bowden cable 23, the wire pull 29 not only penetrates the free end of the release lever 24 but also the lower free end of the detent lever 26, as can be seen in FIG. 3, left half of the figure. To maintain the distance and for fine adjustment, a spacer bushing 30 is arranged between these areas.
  • the head part 4 projects in some areas beyond the axis of rotation 2, it is mounted in an elongated hole guide 31 on the central part 5, which, as is known per se, sinks slightly downwards during this pivoting movement.
  • the described embodiment of the invention can be modified in many ways without departing from the basic idea.
  • the invention is not limited to the reproduced design of the handle device.
  • Electrically acting trigger mechanisms can also be provided here, e.g. B., as already mentioned above, a magnetic pivoting or actuation of the release lever 24 or the locking lever 26.
  • two gas pressure springs can be provided.
  • an electric motor drive can also be arranged here if this were necessary.
