Definitions

  • each support bar which are attached near the ends of each support bar.
  • the cavities of all bellows are connected to one another via pipes, a pressure relief valve being connected to this hydraulic system.
  • the bellows are round and have a diameter that is slightly larger than the width of the support strip.
  • pistons can also be equipped with different diameters or with different active surfaces, so that, for. B. rest when using lower gravity leg parts on support bars that are less stressed and have pistons with a smaller effective area.
  • DE-A1-28 32 584 discloses a lying surface consisting of a plurality of grate elements arranged in the transverse direction.
  • the grate elements which are supported by a pressure medium common to all grate elements, can be supported for the buttock area in addition and parallel to a pressure medium support by flexible support elements, which can be mechanical springs or air springs.
  • WO 89701 749 discloses a slatted frame, the slats of which, in order to better balance the weight distribution of a human body, are supported at their ends in the region of the longitudinal frame parts by means of a piston-cylinder arrangement on the longitudinal frame parts.
  • the hydraulically or pneumatically effective spaces of the piston-cylinder arrangements are connected to one another in a hydraulic or pneumatic connection.
  • EP-A2-0 354 271 discloses a slatted frame in which the slat ends are each held on a flexible device via joints, which are each formed from a hinge pin with a spherical or ellipsoid-shaped joint head and a guide bush into which the joint head is fitted .
  • the resiliently designed resilient device consists of an elastic band, which is guided via rotatably but fixedly arranged rollers on the frame, which are arranged on at least both sides of the points at which the joints are supported.
  • the invention has for its object to improve the mattress described above with regard to its adaptability under loads.
  • the kinematic coupling of the individual lifting elements can in principle be done in any way, that is, for. B. mechanically, hydraulically, pneumatically and / or magnetically / electro-magnetically.
  • a pneumatic kinematic coupling of the lifting elements is provided according to the invention.
  • the bellows provided according to the invention does not require any external guidance with regard to its height adjustment, so that there is no significant frictional force when adjusting the height of the support strip. So that a volume change only causes a change in height of the expanding body, this may, for. B. do not allow lateral bulges or the like.
  • a pneumatic kinematic Coupling is the counterforce holding the support strips in equilibrium with regard to their altitude by the air pressure of the coupled lifting system multiplied by the effective cross-sectional area of the corresponding lifting element; the damping is ⁇ .
  • the lifting height of the individual support strips is not technically limited.
  • each support strip is largely stiff, but is of a lightweight construction.
  • the support strip itself can also be designed to be resilient, since it does not influence the coupling principle in the static state.
  • the support carrying the support strip must be rigid in any case.
  • the effective length of the expanding body is proportional to its load.
  • the support strips are therefore supported via their supports each over a more or less large length directly on the centrally arranged bellows, so that only a slight change in the height of the bellows causes a relatively large change in volume.
  • damping according to the invention is built into the kinematic coupling. This also prevents a suddenly loaded support bar from being pressed in too quickly. It is expedient to adapt this to the individual circumstances if this damping is adjustable.
  • the expanding body has cross-sectional stabilizers.
  • the sub-mattress according to the invention enables a largely force-free and thus work-free contour adjustment and without the use of any spring elements.
  • the lifting element designed according to the invention is very low.
  • Retractors can be provided for each support bar, which, when relieved, turn the support bar back into its horizontal starting position (as seen in the longitudinal axis section).
  • Figure 1 shows a base mattress in the form of a slatted frame for a bed, with individually mounted, arranged transversely to the lying support rails 1, which together the support surface for z. B. form a mattress.
  • Each support bar 1 can be freely pivoted from its horizontal position, seen in cross section, about an axis of rotation 3 lying as closely as possible parallel to its longitudinal axis 2 (see FIG. 12) within a limited pivoting range.
  • the bottom mattress shown consists of individual support strip sections 4, one of which is shown in Figures 2 and 3.
  • a support strip section 4 each comprises a support strip 1, a support strip support 5 designed as a U-shaped bracket, a lifting element 6 forming a support for the support strip support 5 and a forced parallel guide for the support strip 1 when the height is shifted.
  • This forced parallel guide consists of two downwardly projecting racks 7, which are formed by the two U-legs of the support bar support 5 and each cooperate with a gear 8 rotatably mounted in the support strip section 4, these two gears 8 rotating in opposite directions via a crossed rope 9 are coupled together.
  • the illustrated embodiment shows that each support bar 1 is largely rigid. In conjunction with the illustrated parallel guide 7, 8, 9, this ensures that any pressure load on the support bar 1, regardless of its point of application, leads to a vertical parallel displacement of the support bar 1 to itself. A tilting of the support bar 1 about a horizontal transverse axis is thereby excluded.
  • the lifting element 6 used in each support strip section 4 is shown in more detail in FIGS. 6 to 9.
  • the lifting element 6 comprises an air-filled expansion body 10 with an air connection 11 provided on its underside.
  • the expansion body 10 is an upright bellows, the air-receiving space of which is rigid in its cross-sectional contour and is variable only in terms of its height.
  • Each bellows fold 12 can consist of a hose part which is closed on all sides and which is connected to the adjacent bellows fold 12 via air exchange channels 13 (see FIG. 8).
  • the expanding body 10 is provided with cross-sectional stabilizers 14 which, for. B. consist of sheet metal and can be arranged between the bellows folds 12 and on the top and bottom of the expansion body 10.
  • Figure 9 shows that the expanding body 10 is slightly narrower than the associated support bar 1 and is arranged approximately centrally below this. In this case, the effective length of the expansion body 10 can be made shorter in areas where the load is usually lower.
  • FIG. 9 shows that the shortest expanding body lengths are provided in the head and leg area.
  • each support bar 1 When the bearing surface is unloaded, each support bar 1 is in an equilibrium position with respect to its height position and its corresponding counterforce. From this equilibrium position, the support bar 1 can be raised to the highest position shown in FIG. 2 or lowered to the lowest position shown in FIG. 3. With regard to this lifting or lowering movement, all lifting elements 6 are positively connected to one another via a kinematic coupling in such a way that only one support strip 1 is loaded when the latter is loaded Lowering from their equilibrium position by an amount x leads to the lifting of all other support strips 1 from their equilibrium position, the sum of all these strokes corresponding approximately to the lowering x (if the effective length of all lifting elements is the same).
  • a pneumatic kinematic coupling of the support strips 1 is shown as an exemplary embodiment, consisting essentially of an air distributor, to which all the lifting elements 6 are connected with their air connection 11.
  • the air distributor is shown in particular in FIGS. 2, 3, 10 and 11 and comprises an air distributor pipe 15 which is arranged in the longitudinal direction to the lying surface and approximately centrally below this and which has a connection 16 for the air connection 11 of each lifting element 6.
  • An externally adjustable damping is built into the air distributor. This consists of an inner tube 17 which is inserted concentrically into the air distributor tube 15, which has bores 18 assigned to the connections 16 of the air distributor tube 15 and can be rotated and / or displaced with respect to the air distributor tube 15 by means of an end handle 19.
  • Relative displacement of the inner tube 17 with respect to the air distributor tube 15 thus results in a central adjustment of the throttle openings formed between the bores 18 of the inner tube and the connections 16 of the air distributor tube 15 and thus an externally adjustable and changeable damping, which a jerky lifting of unloaded support strips 1 sudden heavy load and thus deep indentation of one or more other support strips prevented.
  • the handle 19 include a fill valve.
  • FIG. 12 shows various exemplary embodiments for the design of the support strips 1 and their storage:
  • support strip 1 consists of two parallel individual strips 1a, 1b which are connected to one another via a support 20 which is pivotally mounted in the center between the individual strips.
  • the individual strips 1a, 1b can be rotatably or pivotably mounted on the carrier 20.
  • the individual strips 1a, 1b consist of round bars, while in the other example the individual strips are formed by flattened profiles.
  • a coupling 21 which may be formed by a wire.
  • stops 22 limiting the pivoting of the support strips 1 can be provided.
