Definitions

• the invention relates to a base for lying or sitting according to the preamble of claim 1.
• Such a bed is known from DE 32 32 123 AI.
• the hoses are arranged in channels and the crossbars are designed as boards, the broad side of which lies on the hoses.
• the ends of the boards are guided in slots on the inside of the channels, being arranged below the upper edge of the channels. This means that the area of the crossbars above the tubes cannot be used as a support for a mattress or the like. Upholstery can be used.
• the object of the invention is to provide such a base that allows a problem-free exchange of the cushion as well as the other parts with a maximum lying surface and simple structure. This is achieved according to the invention with the pad characterized in claim 1.
• Advantageous embodiments of the document according to the invention are given in the subclaims.
• the upholstery, the hoses, the cross bars and the other parts can be exchanged without any problems.
• the crossbars are preferably loosely on the hoses. They are guided so that the crossbars cannot move in the direction of load during their back and forth movement.
• the crossbars are arranged according to the invention in such a way that they protrude beyond the guide.
• the guide for the crossbars can be designed differently.
• the crossbars can be guided in slots which are provided in webs which extend along the base. So that the upper edge of the crossbars always protrudes above the webs, the crossbars have a height that is greater than their immersion depth in the slots.
• the crossbars are preferably designed as boards which are arranged upright.
• guide rods attached to the cross rods or the substructure and guide members attached to the substructure or the crossbars can be provided for guiding the crossbars, into which the guide rods are inserted, so that the guide rods and the guide members are mounted so as to be mutually displaceable.
• the guide member can be formed by a hole in the substructure.
• the guide rod is formed by a piston fastened to the cross rods, and the guide member by a cylinder which is firmly connected to the substructure and in which the piston is displaceably mounted.
• the hoses preferably consist of a non-expandable material, in particular a fabric hose, ie a pressure hose, such as a fire hose.
• the fabric can be embedded in a thermoplastic plastic.
• the hoses can have a constant diameter over their entire length. However, it is also possible to provide the hoses with constrictions or an enlarged diameter in certain areas.
• the hoses are preferably filled with a liquid, in particular water, or a granulate, and only partially, preferably less than four fifths and more than a quarter, in particular less than three quarters and more than half. Due to the non-expandable hoses, which are partially filled with a liquid or granulate, an even distribution of pressure on the body is achieved and thus a significant improvement in lying comfort.
• the crossbars are preferably formed by wooden slats or boards.
• the substructure is preferably made of wood.
• the underlay according to the invention can in particular be designed as a slatted frame for a bed frame, in particular a bed box. The substructure is then supported on the support strips, which are normally attached to the inside of the two long sides of the bed box.
• the underlay according to the invention can also be provided on a seat, in which case it can form the seat surface, but also the backrest.
• FIG. 1 is a side view of the slatted base according to the first embodiment in the unloaded state
• FIG. 2 shows a side view corresponding to FIG. 2 when loaded by a body lying thereon;
• Fig. 3 is a plan view of the slatted base according to Figures 1 and 2 without a mattress.
• FIG. 4 shows a cross section through the slatted frame along the line IV-IV in Fig. 1.
• Figure 5 is a plan view of another embodiment of the guide of the cross bars.
• FIG. 6 shows a longitudinal section corresponding to FIG. 1 of another embodiment of the slatted frame
• 7 shows a cross section corresponding to FIG. 4 of the other embodiment of the slatted base
• Fig. 8 is a partial view of Figure 7 in an enlarged representation.
• FIGS. 4 and 7 shows a cross section corresponding to FIGS. 4 and 7 through a further embodiment of the slatted base.
• Fig. 10 is a partial view of FIG. 9 in an enlarged representation.
• the slatted frame 1 has cross bars 2 as a support for a cushion 6 shown only in FIGS. 1 and 2, which are formed by upright slats.
• the slats 2 are arranged at a distance a from one another which corresponds approximately to the width b of the slats 2.
• the distance a can also be smaller or larger, for example three times or more the width b. This depends in particular on the thickness and strength of the cushion 6, which lies on the cross bars 2.
• the guides are formed by slots 3, which are provided in parallel webs 4, 5.
• the webs 4 and 5 which are formed for example by boards, are fastened to cross members 8, with which the slatted frame 1 rests on support strips 7 (FIG. 4) on the inside of the long sides of the bed frame, not shown.
• a longitudinal beam 9, for example a board is fastened on the cross members 8.
• Hoses 10, on which the crossbars 2 rest lie on each longitudinal beam 9 on both longitudinal sides of the slatted frame 1.
• the hoses 10 are formed, for example, by pressure hoses filled 2/3 with water.
• the two hoses 10 are laterally fixed by the webs 4, 5.
• the slatted frame 1 is closed on the end faces by boards 18, 19.
• the tubes 10 are also fixed in the longitudinal direction.
• the substructure 19 of the slatted frame 1 is formed by the cross members 8 and the receptacles 11 arranged thereon for the hoses 10 with the longitudinal members 9.
• the cross bars 2 are guided with their parallel longitudinal sides up and down.
• the slats 2 must have a height h and the guide slots 3 have a depth t such that the crossbars 2 cannot be moved out of the guide slots 3 when they are displaced by the hoses 10.
• the crossbars 2 are only allowed to immerse into the slots 3 to such an extent that the upper edge of the crossbars 2 always projects above the upper edge of the webs 4, 5, which means that h and t as well as the diameter and the degree of filling are matched accordingly the hoses 10 required.
• a bracket 12 can be fastened to the web 7, as shown in FIG. 5, the two legs 13 of which extend laterally along the guide slot 3.
• the legs 13 form guide rods for each sleeve-shaped guide member 15 which are fastened to the cross rod 2.
• the guide of the cross bars 2 in the loading direction according to arrow B is thus also formed by the guide members 15, which are slidably mounted on the guide bar 13.
• the bracket 12 and guide members 15 can be made of plastic, for example. At their end facing away from the hose 10, the guide rods 13 are provided with stops which are formed by resilient barbs 17 of the plastic hanger 12.
• the transverse rods 2 are at the same time secured against displacement in the transverse direction of the slatted frame 1, that is to say in their longitudinal direction.
• each longitudinal beam 9 consists of a board and two narrow side walls 20 formed, for example, by boards, which are each provided on their upper edge with a strip 16, for example made of plastic .
• the hose 10 is arranged laterally above the upper edge of the side walls 20, as a result of which, in contrast to the embodiment according to FIGS. 1 to 5 with the side walls 4, 5, no friction noises can occur through the hose 10.
• the side walls 20 are chamfered inwards and downwards. They are also designed to be as low as possible so as not to hinder the cross bars 2 when the hose 10 is compressed.
• two guide bars 21 are arranged at a distance from one another on each cross bar 2, so that two rows of guide bar 21 extend along the slatted frame 1.
• the guide rods 21 are each inserted at one end into a blind hole 22 on the underside of the respective cross rod 2.
• barb-like projections 23 are provided on the end of the guide rod 21 facing the cross rod 2, which projections 23 are designed such that this end of the guide rod 21 is inserted into the blind bore 22, but can then no longer be pulled out .
• holes 24 are provided in longitudinal webs 25, which extend along the slatted frame 1 at a distance from one another and are fastened on the cross members 8 laterally next to one or the other hose support 11.
• the longitudinal webs 25 are thus firmly connected to the substructure 19.
• the longitudinal webs 25 can consist of wooden strips.
• sliding bushes 26, for example made of plastic can be provided in the bores 24.
• the longitudinal webs 25 can also consist entirely of plastic.
• a stop is provided at least above the longitudinal web 25 or the sliding bushes 26.
• a plurality of bores 27 are provided along each guide rod 21, into which cross pins 15, 16 can be inserted.
• the guide rods 21 can additionally have a barb-shaped stop 28 at their lower end, which can be inserted through the bore 24 from above, but can then no longer be pulled out of the bore 24.
• the guide rods 21, including the barb-like projections 23 and 28 can be made of plastic.
• the maximum and minimum height of each cross rod 2 can be set individually when using the bed.
• the tubes 10 can also have different diameters along the slatted frame 1. With a larger diameter in certain areas, a softer suspension can be achieved there.
• the cross bars 2 are connected to the substructure 19, that is to say the cross and longitudinal beams 8, 9 by pistons 30, which are attached to the crossbars 2 and are slidably mounted in cylinders 31 which are firmly connected to the substructure 19.
• two pistons 30 are arranged at a distance from one another, so that two rows of pistons 30 or cylinders 31 extend along the slatted frame.
• the cylinders 31 are embedded in bores 32 in longitudinal webs 33 which are arranged on the cross members 8.
• a piston chamber 34 is closed off by the piston 30, in which the air is compressed when the piston 30 is pushed into the cylinder 31 or in which a vacuum is generated when the piston 30 is pulled out of the cylinder 31.
• the damped movement suppresses sliding and rubbing noises.
• the piston 30 and the cylinder 31 are preferably made of plastic.
• the piston 30 can also be hollow.
• the cylinder 31 has a collar-shaped radial projection 35 with which it is supported on the longitudinal web 33.
• the piston 30 is provided with a longitudinal groove 36 into which a projection 37 on the cylinder 31 engages.
• a plurality of transverse bores 38 are provided along the piston 30, into which a transverse pin (not shown) can be inserted.
• the maximum depth of the crossbar 2 can thus be set.
• the piston 30 is pulled out of the cylinder 31 to such an extent that the transverse bore 38 protrudes beyond the collar-shaped projection 35, into which the transverse pin (not shown) is inserted, which then determines the lowest position of the transverse rod 2 as a stop.
• the cylinder 31 has an opening 39 in its peripheral wall. If the transverse pin, not shown, is inserted into the opening 39 and through one of the transverse bores 38 aligned therewith, the movement of the transverse rod 2 is completely blocked. Limiting the movement of the crossbar or blocking it may be desirable, for example, in the case of a couch in the head area.
• the piston 30 is attached to the crossbar 2 via a ball joint 41. This allows the crossbar 2 to adapt better to the body. The forces, for example when getting on the couch, are better distributed. In addition, there are no clamping forces in the cylinder 31, which can cause friction noises, for example.
• the ball joint 41 consists of a joint ball 42 on the piston 30 and a ball socket 43 which is inserted into a blind bore 44 in the crossbar 2.
• the spherical shell 43 is provided on the outside with barb-shaped projections 45, which are designed such that the spherical shell 43 inserted into the blind bore 44 can no longer be pulled out.
• the spherical shell 43 has a radial collar-shaped projection 46 which is arranged on the underside of the slat 2 around the blind bore 44.
• the spherical shell 43 is also preferably made of plastic.
