Definitions
- the invention relates to a slatted frame.
- the slats are usually firmly connected to the slatted frame.
- the slatted frames only partially allow a person lying on a bed to have a body-appropriate and contour-conforming adaptation to the shapes of the body, since the slats are more or less immovable in the vertical direction
- DE 38 15 098 AI discloses a slatted frame with slats, which lie in the unloaded state in one plane and are movably mounted in the vertical direction.
- the slats are stored on stretchable bands that are stretched in the longitudinal direction of the slatted frame between fixed end points.
- the slats are firmly connected to the bands at crossing points.
- de Bander lie on sockets.
- the tapes are stretched with slats. If several battens are used, it is not possible to compensate for the stress by the stretchable tape at an unloaded point.
- the object of the invention is to provide a slatted frame which enables a contour-compensating and body-appropriate adaptation to the contour of a body.
- the slatted frame according to the invention comprises slats which are mounted in a plane lying bearing points.
- the bearing points of the slats are connected to one another via a two- or three-dimensional storage medium which has essentially fixed dimensions or a constant volume.
- the bearing points can be moved downwards in the vertical direction by the body weight and upwards for load balancing. A downward movement of the bearing points under weight load results in a corresponding countermovement upwards in another position.
- the slatted frame according to the invention is thus able to give way under load and to adapt to the contour of a body by means of vertical compensatory movements.
- a movement of the bearing points of the slats out of the plane in the unloaded state is caused by a movement of small or unloaded bearing points out of the plane. ne accompanied upwards.
- the two-dimensional storage medium of fixed dimension can be a rope that has a fixed length and is fixed with both ends.
- the compensating movements of the bearing points are achieved by deflecting the rope, ie deflecting the rope at one point results in a shortening at another point.
- An example of a three-dimensional storage medium with a constant volume is a chamber filled with liquid, in which the compensating movement is based on the displacement of the medium or its spatial displacement. The extent of the compensatory movements depends on both the load and the contour of the body.
- the sum of the distances of the bearing points from the plane upwards can be equal to the sum of the distances of the bearing points downwards.
- the individual bearing points of the slats then carry out compensatory movements in the vertical direction until they have adapted to the contours of a body, i.e. until a balance is reached. Due to the possibility of moving the bearing points of the slats vertically, the inadequate load-balancing ability and the inadequate ability to adjust the contour of conventional slatted frames are avoided. This results in a balanced rest position for a person, especially in the back or side position, which protects against health damage and enables a relaxed and health-promoting sleep.
- the slatted frame has a frame
- the stationary deflection means are attached to the frame.
- the portable deflection means are the bearing points for the slats and the fixed and portable deflection means are connected by a storage medium in the form of an elongated, flexible, non-stretchable support element.
- the slatted frame of this exemplary embodiment is composed of very simple and a small number of parts and can be produced inexpensively.
- a practically two-dimensional support element is provided as the storage medium, which is, for example, a rope, a band or a belt.
- the support element is not stretchable or essentially not stretchable.
- a supporting element is expediently provided along each side rail of the frame. All parts with the exception of the supporting element can be made of wood, which means that the slatted frame can be made of natural materials.
- the portable deflection means can move vertically under load down.
- the available length of the support element between the stationary deflection means, which are arranged adjacent to the loaded, variable deflection means must be increased. Due to the fixed overall length of the support element, this enlargement is speaking accompanying reduction of the available length of the support element at other locations of the slatted frame. This local shortening is possible at places where there is an unloaded or less loaded portable deflection means. This means that at this point the variable deflection means moves vertically upwards due to the reduction in the length of the support element.
- the length changes of the support element between adjacent fixed deflection means take place until a load compensation has taken place and the slatted frame has adapted to the contour of a body located on it.
- the load of loaded bearing points is distributed to unloaded or less loaded bearing points via the support element.
- the fixed deflection means are preferably fastened to the frame near the upper edge of the frame in order to keep the distance of the plane of the movable bearing points from the frame as small as possible for a given dimension of the support element. In this way, a low overall height of the slatted frame can be achieved.
- the deflecting means are e.g. Rolls, eyelets or hooks.
- at least one portable deflection means is arranged between the fixed deflection means. Since the number of fixed and portable deflection means is minimal in this arrangement, the number of friction points between the support element and deflection means is small and the compensating movements of the slats are only slightly hampered by the friction.
- the movable deflection means are advantageously attached directly to the slats. In this way, the local other deflecting means below the stationary deflecting means and the frame limits slipping of a mattress (or a futon or the like) placed on the slats to the front or to the rear or to the side.
- Spacers are preferably provided in the slatted frame according to the invention, to which the stationary and / or changeable deflection means are attached.
- the position of the slats with respect to the frame can easily be changed using spacers.
- the spacer elements and deflection means attached to them the distances between the stationary and the variable deflection means and thus the maximum deflection path of the support element can be varied. If, for example, for a given length of the support element, instead of one, a plurality of movable deflection means is attached to a spacer element around which the support element is guided, the vertical movement possibility of the individual movable deflection means is reduced.
- the spacing elements of the variable deflection means can be bars, strips or trapezoidal supports.
- the fastening of the slats to trapezoidal supports, on which at least two movable deflection means are attached represents a particularly stable mounting of the slats, since they are supported at several points
- the spacing elements of the variable deflection means are arranged vertically to a plane in which the slats lie in the unloaded state. This arrangement enables that ⁇ ie slats ⁇ part or all of a position above the frame Definden. This means, for example, that a mattress is placed on the slats Arranged above the upper edge of the frame and the risk of a person injuring himself on the frame when going to bed or getting up is reduced.
- the spacing elements of the stationary deflection means are preferably vertical connecting pieces attached to the frame.
- the position of the stationary deflection means in relation to the frame can be changed by means of the connecting pieces.
- the sockets are attached to the frame such that one end of the sockets is directed vertically upwards, the stationary deflection means can be attached to this end and the frame of the slatted frame can be placed directly on the floor.
- the frame advantageously has side rails, the side rails each having an inner wall and an outer wall, between which the stationary deflection means are fastened.
- the stationary deflection means can be attached in two places. This increases the load-bearing capacity of the stationary deflection means and enables the stationary deflection means to be securely attached.
- the storage medium is fluid housed in a chamber, the bearing points of the slats being on the top of the chamber.
- An essentially constant volume fluid is used as the storage medium.
- the load and contour are compensated for by displacing or shifting the fluid. If the fluid is assumed to be m-compressible, for example, the displaced fluid volume at one point in the chamber corresponds exactly to the added fluid volume at another point.
- the slatted frame according to the invention is also functional with compressible fluids. Here, before the fluid is displaced, there is a first Compression dependent on the existing pressure in the fluid, similar to a gas cushion, followed by the actual displacement process.
- the fluid should expediently have a sufficiently high pressure in order to be able to achieve the intended displacement.
- the chamber is designed such that the displacement or volume displacement processes for load balancing lead to vertical movements of the individual bearing points of the slats up and down out of the resting vein. In this way, the load-balancing and contour-adjusting effect of the slatted frame is achieved.
- the slatted frame of this exemplary embodiment can be arranged in a frame or directly on the floor.
- the chamber advantageously has, on the top side, substantially vertically aligned cylinders in which pistons can be displaced, one side of the pistons limiting the fluid and the other side of the pistons being coupled to the bearing points of the slats.
- a flexible material is advantageously used for the chamber wall. Since the slats found at the top of the chamber be ⁇ are slats that are being loaded by a person, moves vertically downward due to the downward acting load, because the chamber is printed there, and the fluid displaced in this region of the chamber . This change in shape of the chamber is associated with a bulge or bulging of the chamber wall elsewhere. The slats, which are less or unloaded, experience corresponding vertical compensatory movements upwards.
- the slats are preferably mounted on knobs on the flexible chamber. This enables the slats to be stored stably. In addition, the slats can be pivoted about their longitudinal axis without additional pivoting devices.
- slats which are subjected to a load, for example due to the weight of a person, are moved downwards in the vertical direction.
- the piston in the associated cylinder displaces the fluid. Accordingly, slats that are less or not loaded move vertically upwards over the pistons until they are adapted to the contours of a body lying thereon, and load balancing has taken place.
- the storage media of which is a fluid housed in a chamber two longitudinally extending fluid chambers are provided for the storage of the slats.
- this slatted frame can be placed on the floor in a stable manner, and ventilation of the mattress from below is ensured between the long chambers.
- the slatted frame according to the invention is preferably divided into at least two sections which can be pivoted with respect to one another.
- part of the slatted frame can be adjusted as a head or foot part or the slatted frame can be used in a collapsible bed. It is also possible to use this slatted frame version for seating or upholstered furniture.
- the slats are advantageously mounted so as to be pivotable about their longitudinal axis. This enables the slats to be more precisely adapted to the 3ela- stung, especially in places where loaded and unloaded slats lie next to each other, whereby a better contour adaptation to a body is achieved.

- two portable deflection means 22 are provided at the other end of the carrier 28. The vertical compensatory movements are carried out as in the two previous exemplary embodiments.
- the slatted frame shown comprises a chamber 31 in which a fluid 32 is located as the storage medium. In the exemplary embodiment shown, this fluid is a liquid, such as water.
- the chamber 31 is made of an inflexible material.
- Pistons 37, on which the slats 5 are mounted, can be moved vertically in the cylinders 35.
- the pistons 37 are in contact with the fluid 32 on one side and are connected to the slats 5 on the other side via a piston rod 38.
- the pistons 37 are each mounted on the piston rods 38 by means of slide bearings 39.
- the piston has a seal against the fluid 37 a sealing ring (not shown).
- the cylinders 35 are closed at the top by a cover 36 in which the slide bearing 39 is arranged.
- the chamber 31 has two rows of cylinders 35 (not shown) laterally in the longitudinal direction, so that each slat 5 is supported on two pistons 37 located in the cylinders 35. In the unloaded or evenly loaded state, the pistons 37 are located on a plane 33.

- the vertical compensation movements are made possible by the displacement principle.
- the two outer slats move vertically downward due to a load and the pistons 37 are also moved downward via the piston rod 38 (not shown).
- the two outer pistons 37 displace a certain volume of the fluid 32, which is located in the cylinder 35 below them. Since the fluid 32 as a whole has a constant volume, the central piston 37 which is not loaded is simultaneously pushed vertically upwards due to the displacement of the fluid volume at the loaded points. The desired compensating movements are thereby obtained.
- a fifth exemplary embodiment ei ⁇ nes inventive shaped slatted base is shown.
- This slatted frame also works on the principle of displacement. It has a chamber 45 made of flexible material, which contains a fluid 46. Two elongate chambers 45 are provided, which are arranged in parallel. Each slat 5 points as Lagerstelien two knobs 47, which are connected to the chambers 45. Since the chambers 45 are flexible, loaded slats 5 move vertically downward due to the load. This results in a change in the shape of the flexible chamber 45 at the bearing points of the loaded slats 5 and a displacement of the volume of the fluid 46, which is located in the chambers 45 below the loaded slats 5. Since the volume of the fluid 46 is essentially constant, slats 5 which are not or only slightly loaded move vertically upwards at the same time and carry out the vertical movements which balance the load and the contours.
