Definitions

  • the invention relates to an adjustable bed frame according to the preamble of the first claim.
  • a device for pivoting raised parts on the matrix frame is known, DT 24 20 598 AI, which has adjusting levers which rest against the inner frame below the latter, the adjusting levers being connected to one another via a common drive shaft on which a lever arm is arranged in a rotationally fixed manner is, which is connected via a rod-shaped coupling element to the adjustment drive, which in turn is articulated on a transverse axis fixed in the frame.
  • the disadvantage of this known construction is that it is very complex and requires many different components, that very strong torsional moments can occur in the drive shaft for the adjusting levers with an uneven load on the lying surface, so that either the drive shaft must be relatively solid and heavy or but the inner frame of the bed frame, as otherwise it would twist very much if one-sided loading was applied.
  • the object of the invention is to provide an electromotively adjustable bed frame which is simple and made up of a few components and can be produced inexpensively.
  • the coupling element for each adjusting lever consists of a traction means, which can be wound on a shaft driven by the adjusting drive
  • the adjustment drive can, for example, be fixed to the frame on one of the longitudinal or crossbars are attached without it having to be pivotally mounted in order to compensate for an angular offset of a drive moving a massive push or push rod.
  • the torsional load on the drive shaft is also eliminated, the shaft driven by the adjusting drive having such a small diameter that the traction means wound thereon can exert only a very low torque on the shaft.
  • this adjustable bed base is that the traction means can be easily cut to length, so that the distance from the adjustment drive to the adjustment lever can be freely selected.
  • this inventive construction has a very low weight and does not require any complex fittings for fastening to a frame, so that this adjusting mechanism can also be easily retrofitted to existing bed frames.
  • the shaft for winding the traction means can simply be adapted to the inside width of a bed frame, so that the construction according to the invention is also completely independent of the width of a bed frame.
  • this construction has a very low overall height, so that the transport costs of the finished bed gratings are significantly reduced compared to other electromotively adjustable bed gratings.
  • the construction is not limited to batten gratings with slats, but can also be used for bed gratings with separate grate surfaces that are equipped with individual spring elements, for example.
  • the adjustment drive is arranged on a longitudinal spar in a frame-fixed manner and the traction means is designed as a simple belt or braided band with high tensile strength.
  • Spring steel strips or chain-like structures can also be used as traction means.
  • Such a tape can then be wound up in layers on the shaft to form a roll directly on the shaft or on a separate roll-up segment, which can additionally be provided with lateral guides.
  • the adjustment drive can also be arranged externally on a bed frame or a bed box, so that an optimal placement is possible regardless of the type of bed.
  • the traction means is designed as a simple rope, wire rope or plastic rope with a round cross section.
  • a wire rope with a plastic coating is preferably used for this purpose, so that the risk of injury to the plastic wire rope as well as wear is minimized with a high degree of flexibility. Furthermore, this affects a more uniform winding on an area of the shaft driven by the adjusting drive, which area is designed as a winding device and in which one end of the traction means is fixed, which is wound on the shaft by rotation about it.
  • the traction device is given a lateral initial orientation, so that all subsequent turns are arranged next to each other when winding.
  • An embodiment is advantageous in which a circular cylindrical reel segment is arranged on the shaft, which has a helical annular groove for receiving the traction means, so that the desired orderly shape of the winding of the wire rope on the shaft or the reel segment is further supported.
  • the roll-up segments used for the various traction means can have different outer diameters, so that their exchange makes simple and rapid variation in the speed of movement or tractive force possible without the need for further changes to the adjustment drive .
  • the adjustment drive can be optimally adapted to all existing sizes and dimensions of the most varied bed frames.
  • a particularly advantageous embodiment has as the drive an electric motor arranged in a tube, similar to a roller shutter drive, on which the traction means is wound up.
  • the traction means preferably acts on the end of the lever arm, which is designed as a functional unit with the adjusting lever, in particular in one piece, the line of action of the force running through the traction means and below the pivot bearing of the adjusting lever, so that no lateral forces or moments act as a whole Mechanism may be generated that could adversely affect its function and durability.
  • the adjustment drive for pivoting a foot and a back part optionally drives two shafts simultaneously or independently of one another, so that no second motor is required to pivot a second frame part.
  • the adjustment drive is equipped with a corresponding coupling.
  • Fig. 1 is a side view of an adjustable bed frame in partial section and Fig. 2 is a partial view of an adjustable bed frame in a plan view.
  • the adjustable bed frame consists of a frame 3 with two longitudinal spars 9 and two transverse spars 10 and at least one inner frame 2 designed as a pivotable foot or back part.
  • An electromotive adjustment drive 1 is arranged on the frame 3 on a longitudinal spar 10, by means of which a pulling means 6 , a lever arm 5 and an adjusting lever 4, which is articulated below the inner frame 2 on the longitudinal beam 10 and which bears under the side rail of the inner frame 2, which is articulated on the longitudinal frame 10 via a pivot axis 1 2 from a horizontal position into a employed position is pivotable.
  • the adjustment drive 1 here consists of an electric drive, which drives a shaft 7 via a worm drive, which extends across the width of the inner frame 2 and on which in the area of the inner sides of the inner frame 2 a traction means 6 in the form of a belt strap (FIG. 1) and a wire rope (Fig.2) is attached, the other end of which is attached to the lever arm 5 of the adjusting lever 4, so that it is moved about its pivot axis 11 by the rotation of the shaft 7 and the winding of the traction means 6.
  • the rope-shaped traction means 6 is wound on a roll-up segment 1 3, which is fixed on the shaft 7, so that the turns are exactly next to each other.
  • the shaft 7 and / or the roll-up segment 13 have a radial bore slightly deviating from the vertical direction, the angular deviation of which from the normal corresponds approximately to the pitch angle of the windings wound.
  • Band-shaped traction means are rolled up in layers one above the other.
  • the shaft 7 is moved by the adjusting drive 1 or the roll-up segments 1 3 are uncoupled from the shaft 7 so that the traction means can unwind freely.
  • the swiveling speed or the erection force of the inner frame 2 can be varied in a simple manner, so that the most varied inner frames 2 of foot or back parts of the most varied design can be driven with an adjustment drive without further intervention in the mechanics being necessary are.
  • the traction means 6 can also be carried out within the frame via rollers or the like. redirect to another movable or to a more distant frame segment.
  • An adjusting lever 4 is attached to the cross member 10 of a frame 3 below an inner frame 2 via a pivot axis 11, the traction means ⁇ preferably below the pivot axis 1 2 and the adjusting lever 4 in a parallel or almost parallel direction up to the shaft 7 extends so that no additional bending moments are generated in the components.
