Definitions

  • the invention relates to a new spring element, the z. B. in so-called Slatted frames are used, mainly in seating or reclining furniture is used.
  • the slatted frame takes on the support function in most cases for mattresses or upholstery as well as the basic hardness setting for the Comfortable sleeping or sitting.
  • the hardness due to rubber elements is between two Female connectors are slidably mounted, adjustable.
  • the hardness of the female connectors is by one or more shorter spring elements attached to the female connector are slidably attached, the hardness of the female connector is adjusted.
  • the object is achieved in that between the support points in the longitudinal direction of the spring element, a clamping element, which in at least a first transverse direction is deflectable, with adjustable Preload is tensioned on train and along the tensioning element on the Chain elements connected to one another between the load points are arranged so that the chain elements in the longitudinal direction support each other and about swivel axes that are transverse to the longitudinal direction and extend transversely to the first transverse direction, are pivotable relative to one another.
  • the advantages achieved by the invention are in particular that the in its hardness easily and precisely adjustable spring element especially for Nursing beds, at home or in hospitals, clinics, sanatoriums, old people's and Nursing homes, is suitable, since here special variable setting values regarding the Pressure distribution and sinking depth in the support area are required. Also are most nursing beds adjustable in the head and foot section and the mattress can this is because their height is less than one due to the bending requirements normal sleeping mattress, not the function of an optimal anatomical Support the spine and lumbar spine. Due to this the slatted frame is of particular importance with regard to the sinking depth and Pressure distribution too.
  • Another advantageous embodiment of the invention is in addition to the simple manual adjustment of the hardness of the spring elements, e.g. B. by a simple Torque wrench, the programmed control of hardness by individual Spring elements using software and electric stepper motors.
  • This application is advantageous for nursing and hospital beds with one constantly changing bed occupancy and different clinical pictures of the Patient. Long-term and long-term care patients can be out of medical Intermittent control over a defined period of time the hardness of different hardness zones or of individual spring elements can be realized via the electronic control.
  • the spring element according to the invention consists of FIGS. 1 and 2 at least one clamping element 4, which between the ends 5 and 6 in Longitudinal direction 7 runs and which is in at least a first transverse direction 32 is deflectable, is tensioned with tension and adjustable along and along the tensioning element 4 on the load side between the ends 5 and 6 interconnected chain elements 1 are arranged so that the Support chain elements 1 in the longitudinal direction 7 and around swivel axes 8, which is transverse to the longitudinal direction 7 and transverse to the first transverse direction 32 run, are pivotable relative to each other.
  • the chain elements 1 are thereby articulated to each other that they with their from the tensioning element facing backs are firmly connected to an upper chord 14, which over the entire length of the spring element from one end 5 to extends other end 6 and is also firmly connected to the ends 5 and 6 and Resiliently deflectable in the transverse direction, but is pressure-resistant in the longitudinal direction 7.
  • the chain elements 1 form in FIG Unloaded transverse direction with their front of the clamping element 4th averted back in its entirety a mirror-symmetrical crowned overall convex contour. Because of these different heights of the chain elements 1 is except for the ends 5 and 6, which are also the support points for the spring element form, one between the ends 5 and 6, at every point, the same sinking depth realizable.
  • Fig. 5 shows in detail that the chain elements 1 only over the top chord 14th are interconnected, and on the end faces 9 only against each other be pressed, and these end faces when deflected in the first transverse direction roll on each other and the roll-off point has a transverse pivot axis represents.
  • the chain elements 1 are on a lower flange 15 attached to a central 16 or lateral 17 support the Realize spring element while the clamping element 4 on the top runs.
  • a spring element with an upper chord 14 is over a connecting element 18 connected to a female connector 19 to a approximately the same sinking depth of the ends 5 and 6 as between the ends 5 and 6 can be achieved.
  • two female connectors are different Deflection and support in the longitudinal direction one behind the other connected. This combination can be advantageous in the seating area, especially in the Chair area can be used.
  • FIG. 12 there are two spring elements, one with a long one Upper chord 14 and a short one with lower chord 15, via a connecting element 18, that runs in the deflection direction 32, arranged.
  • This combination of two Spring elements allow an exact sinking depth of the upper chain element at all points in the longitudinal direction 7 and is particularly suitable for use in Nursing beds in connection with a central electromechanical control for different hardness requirements that exist from a medical point of view.
  • exemplary embodiments are Spring element shown with central belt 21, which is advantageous in the seating area, especially used in the backrests of office chairs or car seats can, and with the tensioning elements 4 on both sides of this central belt run.
  • FIG. 18 there is a spring element with an upper chord 14 shown, which replaces the chain elements 1 and by a continuous flexible hollow body 22 is formed, and instead of a clamping element 21, a Cross fabric 23, the tension task of the clamping element 4 takes over.
  • damping and compensating elements 26 are located at an excessively strong and different load of the Spring elements such as B. in benches in public areas, the Clamping element 4 or the clamping device relieved.
  • the upper chord of the spring element by means of individual elements 29, which are connected by continuous chain elements which form the Form pivot axes and fix the individual elements 29, formed and thereby offering the constructive possibility of larger contiguous areas for different relaxation areas with different requirements realize.
  • the wide top chord 14 is for a controlled deflection has openings 30, chain elements 1 '' with four End faces 9 and a centering center 31 attached, the clamping elements 4 run lengthways and crossways and are in the center of the centering center cross and thereby a homogeneous deflection with a tapering Pressure distribution curve of the surface in both the longitudinal and transverse directions is realized.
  • Figures 36 and 37 show in longitudinal and cross section a variant in which the upper flange 14 protrudes at intervals against the tensioning element 4, has in particular integrally formed extensions 14 '.
  • the chain elements 1 are plugged onto the free ends of the extensions 14 'and take them in appropriately shaped pockets that are slightly larger than that Extensions 14 '. Deformed transversely to the tensioning element when loaded on the top flange the upper chord 14, so that under certain circumstances also the extensions 14 'no longer are exactly parallel to each other, and the adjacent chain elements 1 roll something against each other with their mutually facing end faces 9 according to the effect of a joint.
  • the clamping element 4 can be a Be tension belt, which lies on a lower groove of the chain elements 1.
  • FIG. 38 shows a variant in which the chain elements 1 Pieces of pipe are in the direction of the clamping element 4, in this case one Clamping element with a round cross-section, such as a steel cable, which extends through the tube.
  • the intermediate upper chord 14 and the tensioning element act primarily as tensioning element 1 4 located part of the cross section of the pipe sections, so that the hinge point the point of contact of these pipe sections on the end faces 9 opposite the extensions 14 '.
  • FIG. 40 shows a variant similar to FIG. 36, but with the clamping element 4 again an element with a round cross-section, such as a steel cable, is used, whose primary difference is the shape of the top chord 14:
  • the upper flange extends on both sides a multiple of the width of the extensions 14 'beyond these laterally is in Cut in the longitudinal direction from the sides at intervals apart from about Depth of the extensions 14 'and has large areas in these lateral projections Breakthroughs.
  • Such a spring element provides support over a large area, without ventilation through the upper chord 14 within this area completely hindering it.
  • FIG. 42 shows an embodiment similar to FIG. 26, with the difference that that on the side of the chain elements 1 facing away from the tensioning element 4 each chain element a laterally wide to the direction of the tensioning element 4 projecting cross-arm 28 is arranged to also by a single Spring element to offer a wide support surface.
  • the chain elements 1 can be connected to each other via individual joints or via a Upper chord 14.
