Description
Piece of furniture for sitting or lying down on
The present invention relates to a piece of furniture for sitting or lying down on comprising a lying or sitting frame and base for a mattress or a seat cushion.
The typical setup of a bedroom furnishing system strongly varies according to re gions. For example, in the Anglo-Saxon region the so-called box spring bed is very popular, while in the European region the conventional bed is favored which com prises a bedframe and a slatted frame upon which the mattress rests. However, in the case of box spring beds a spring-mounted base is used instead of a slatted frame, which base is very massive and high and takes up a lot of space since usually barrel pocket springs having a height of approx. 20 cm are mounted therein. However, with regard to comfortable sleep the box spring bed offers a considerably better sprung base as compared to beds having slatted frames. This is explains the high sales volumes of box spring beds and the recent decline in sales of the slatted-frame beds
From EP 2 762 042 A1 a bed is known which comprises two barrel pocket spring mattresses between which a lying or sitting frame having one or a plurality of tension belts is arranged. The hardness and the height of the bed are adjusted by changing the tension of tension belt.
In US 2013/0000049 A1 a bed is described which comprise a mattress and a slat ted frame having a height-adjustable plate. In the mattress a plurality of spring assemblies are mounted over the entire surface area, wherein each spring assem bly comprises two spring elements concentrically arranged relative to each other. The outer spring element of the spring assembly is in contact with the height adjustable plate of the slatted frame. When the plate of the slatted frame is raised, the spring element in contact therewith is more strongly pretensioned, whereby the hardness of the mattress can be changed.
From US 71,933 and US 93, 632 lamellar mattress bases for a bed are known which are resiliently coupled with a bedframe with the aid of rubber bands.
It is an object of the present invention to minimize or even eliminate the drawbacks encountered in prior art. In particular, it is an object of the present invention to improve the lying comfort of a conventional bed or the sitting comfort of conven tional seating furniture and in particular to make them similar to those of box spring beds.
This object is achieved with the subject matter of the independent claim 1. Optional and/or preferred features of the invention are stated in the subclaims 2 to 16.

Fig. 1 shows a schematic diagram of a bed according to an exemplary embodiment of the present invention. The present invention is not limited to beds in the narrower sense but is applicable to any type of furniture for sitting or lying down on. Here, a sofa and a bed couch are merely exemplified.
The bed 100 comprises a frame means 110 (bedframe), a support means 130 (first mattress base) and a frame springing means 120 serving as a resilient coupling between the frame means 110 and the support means 130. Preferably, further a support springing means 200 (second mattress base) is provided. The support means 130 is configured for being coupled with the frame means 110. The frame springing means 120 is configured for providing a first spring effect between the frame means 110 and the support means 130. The support springing means 200 is configured for provided a second spring effect acting upon the support means 130.
Fig. 2 shows a schematic diagram of a partial aspect of the bed illustrated in Fig. is 1 according to an exemplary embodiment of the present invention.
Fig. 2 shows how the frame springing means 120 is fastened to an upper surface of the bottom plate of the frame means 110 on the one hand and to a lower surface of the floating support means 130 on the other hand.
Fig. 3 shows a schematic diagram of an alternative partial aspect of the bed illus trated in Fig. 1 according to an exemplary embodiment of the present invention.
Fig. 3 shows how the frame springing means 130 is fastened to an inner surface (side wall or side beam) of the frame means 110 on the one hand and to a lower surface of the floating support means 130 on the other hand. This alternative type of fastening of the frame springing means 120 offers the advantage that the frame springing means 120 is not subjected to any friction and thereby the spring travel can be even longer (12 cm in the sprung base, for example). Furthermore, the overall area of the sprung base increases in the width of the lie-down area, which offers a comfort advantage. In this configuration, coil springs or gas pressure springs can be used instead of a spring strap 120.
Mounting a rail at the frame and at the floating bottom plate ensures smooth slid ing and is well suited for preventing vibrations. Furthermore, this rail can be provided with a stopper for causing or limiting a maximum elongation of the springs. In most cases approximately 7 cm are advantageous.
Fig. 4 shows a schematic top view of a bed according to an exemplary embodiment of the present invention.
Fig. 4 shows that for fastening the support means 130 to the frame means 110 two or more frame springing means 120 can be used on each side. Furthermore, Fig. 4 illustrates rails 150 which allow for optimum sliding of the support means 130.
Fig. 4 shows a support means 130 which is divided into a plurality - 3 in the present case - support segments 130-1, 130-2, . . 130-n. In the same manner, the frame springing means 120 comprises a plurality of frame segment springing is systems 120-1, 120-2, . . , 120-n. The support springing means 140 is also divided into a plurality of support springing segments 140-1, 140-2, . . , 140-n. Further, in Fig. 4 a middle guiding strap is illustrated which, as in the case of a slatted frames, ensures additional stability.
When gas pressure or coil springs are used instead of the aforementioned spring straps, it is possible that two rails serve for guiding purposes and one spring per side suffices for an adequate springing.

The setup of a bed according to a preferred embodiment of the invention, merely schematically illustrated in Figs. 1 to 4, will hereunder be described in detail with reference to Figs. 5 to 8.
The setup of a bed 100 illustrated in Fig. 5 corresponds to a preferred embodiment is of the invention. According to this embodiment, the bed 100 comprises a bedframe 110 essentially having a rectangular shape. A wooden frame can be provided as a bedframe which is glued or screwed on and partially supported by steel sections for imparting an adequate stiffness to the bedframe 110. The horizontal dimen sions of the bedframe 110 can correspond to those dimensions usual in the market for conventional beds. The vertical height of the bedframe 110 preferably is 5-25 cm, more preferably 7-15 cm, and still more preferably merely 8 cm.
Although not shown in Fig. 5, the bed 100 can also comprise legs or a pedestal for placing the bedframe 110 at a height for allowing the user to comfortably climb into and get out of the bed 100. Likewise, a distance of the bedframe 110 to the floor beneath allows for ventilation of the entire bed 100 from below.
The bed 100 illustrated in Fig. 5 additionally comprises a (first) mattress base 130 which can preferably be divided into a plurality of segments 130-1, 130-2, 130-3 and 130-4. Here, the division is preferably realized vertically to the longitudinal direction of the bedframe 110. Due to this division various zones for lying down on are created which can support different parts of the body of the user to different degrees. In the various segments 130-1 to 130-4 the mattress base 130 comprises ventilation slots 132-1 to 132-4 which ensure ventilation from below of the bed components located on the mattress base 130. An example of such a bed component is the coil spring support 200 (Fig. 1) which is considered another (sec ond) portion of the mattress base 130 according to another preferred embodiment of the invention.
At least portions of the mattress base 130 are resiliently coupled with the bedframe 110, preferably with the aid of spring straps 120. Thus, some of the segments 130-1 to 130-3 of the mattress base 130 are respectively resiliently coupled, in dependently of each other, with the bedframe 110 with the aid of spring straps 120-1 to 120-3. Merely the segment 130-4 is preferably not resiliently coupled with the bedframe 110. Depending on the size of the segments 130-1 to 130-4 of the mattress base 130 either one or two or even more spring straps 120 can be provided on opposite sides as seen in the width direction of the bedframe 110. The spring straps 120-1 to 120-3 can have different spring constants. Depending on the lying position of the user (e.g. dorsal position, lateral position or abdominal is position) and the desired lying comfort, the spring constants of the spring straps 120-1 to 120-3 can preferably vary in the various segments 130-1 to 130-3.
A spring strap 120 within the meaning of the invention is considered to be any resilient holding element which, when loaded by the weight of the user, ensures downward movement of the mattress base 130 in the vertical direction. Likewise, the spring strap 120 is designed to produce an adequately strong restoring force for the mattress base 130 to return again into its original vertical position once loading by the weight of the user is reduced. These spring straps or belts 120 have a high carrying capacity and can have different spring strengths (spring constants). Preferably, the spring stroke of a spring strap is 5-15 cm, more preferably 5-10 cm, and particularly preferably 6-8 cm. Examples of spring straps are warp knit fabrics, fiber straps e.g. from elastic synthetic fibers, such as Mygroflex, for ex ample, and rubber bands.
The mattress base 130 is coupled with the bedframe 110 such that a vertical down ward, but preferably also upward movement of the mattress base 130 relative to the bedframe 110 is guided. Such guiding is preferably ensured by a linear guide 150 which is operatively connected to the bedframe 110 on the one hand and to the mattress base 130 on the other hand. An example of a linear guide 150 is a slide 154 shown in Fig. 6 which is arranged for linear movement in a guide 152a
(rail). Preferably, the linear guide 150 has an upper stopper and a lower stopper such that a length of the vertical upward and downward movement of the mattress base 130 relative to the bedframe 110 is limited.
As a safety measure, an anti-trap protection can be provided which covers any gaps between the mattress base 130 and the bedframe 110. Especially in the loaded condition of the mattress base 130 a vertical gap can occur such that there is the risk that careless persons, e.g. children, put their fingers into the gap. But any gaps between the segments 130-1 to 130-4 of the mattress base 130 can also be covered by an anti-trap cover, for example an elastic band, e.g. by a textile or mattress drill, for thus making gaps inaccessible. Preferably, the anti-trap cover is placed on the lower side of the mattress base 130 such that any gaps between the segments 130-1 to 130-4 of the mattress base 130 are inaccessible or covered.
is As can also be seen in Fig. 6, the spring straps 120 are preferably fastened, pref erably screwed, to the inside of the vertical side beam of the bedframe 110 with the aid of a metal strap 122. The opposite end of the spring strap 120 extends below the mattress base 130 and is fastened to the lower side of the latter. The same applies to the linear guide 150 whose slide 154 is fastened to the vertical side beam of the bedframe 110, while the slide guide 152a extends through a recess in the mattress base 130.
In Fig. 7 it can be seen how an extension 152b protruding perpendicularly to the vertically extending slide guide 152a extends below the mattress base 130. This extension 152b is preferably fastened to the lower surface of the mattress base 130 via a screw connection.
Alternatively, at least part of the spring straps 120 can be fastened to the linear guide 150, preferably to the slide guide 152a, instead of the side beam of the bedframe 110.
In Fig. 7 it is further shown how the spring strap 120 is configured as a tension belt. For this purpose, the spring strap 120 comprises a bar 124 through which a pin 125 passes that is adapted to engage in a snap-in device preferably comprising two parallel snap-in rails 126, 128.
According to Fig. 8, the snap-in rails 126, 128 comprise recesses 126a, 128a ar ranged at regular intervals. Via these recesses 126a, 128a the pin 125 can be inserted into the hollow spaces 126b, 128b provided beneath and being open on one side, as shown in Fig. 8. These hollow spaces 126b, 128b have a cross-sec tional area extending in parallel to the snap-in rails 126, 128 and being larger than the opening area of the recesses 126a, 128a. Due to the tensile strength of the spring strap 120 the pin 125 moves into that portion of the hollow spaces 126b, 128b which is not exposed by the recesses 126a, 128b. This portion is designated by the reference numeral 128c in Fig. 8. With the aid of these snap-in rails 126, 128 the pretension of the spring strap 120 can be variably adjusted. In this con nection, other pretensioning mechanisms, either of the mechanical or the electrical type, are also conceivable.
is The pretension of the spring strap 120 and the fact that the linear guide 150 com prises an upper stopper ensure that all segments 130-1 to 130-3 of the mattress base 130, which are resiliently coupled with the bedframe 110, in the unloaded condition, i.e. without any external load acting upon it, are at the same height, preferably at the height of that segment 130-4 of the mattress base 130 which is not resiliently coupled with the bedframe 110. The lowerstopperof the linearguide 150 ensures that the mattress base 130 cannot unlimitedly vertically move down ward relative to the bedframe 110 due to the external force, but said movement is limited. This prevents any objects or even persons which/who are temporarily under the mattress base 130 from being harmed.
As indicated in Fig. 1, the mattress base 130 can preferably comprise two mattress base elements 130, 200. In this case, on the mattress base 130 shown in Figs. 5 to 8, which in this case is referred to as a first mattress base element 130 within the meaning of this description, a second mattress base element 200 is arranged which comprises a plurality of coil springs 220 arranged side by side over the entire surface area. Preferably, the second mattress base element 200 can loosely rest on the first mattress base element 130 or be coupled with the latter. Preferably, the coil springs 220 have a spring stroke of 2-10 cm, more preferably 2-7 cm, and particularly preferably 3-4 cm. Preferably, the second mattress base element 200 is a 5-zone barrel pocket spring core which preferably can additionally comprise a comfort foam of e.g. a thickness of 5 mm. The second mattress base element 200 can be enclosed by a flexible mattress drill, for example. Onto this second mattress base element 200 the actual mattress is placed on which the user lies down to sleep. In the case of a seating furniture the actual seat cushion, on which the user sits down, is placed on the second base element 200.
A spring stroke of e.g. 6-8 cm of the spring straps 120, which can however be limited by the lower stopper of the linear guide 150, and a spring stroke of e.g. 3 4 cm of the coil springs 220 of the second mattress base element 200 can amount to a total spring stroke of e.g. up to 12 cm although the overall height of the bedframe 110 is merely 8 cm, for example. Likewise, by a corresponding selection of the spring constants of the spring straps 120 and the spring constants of the coil springs 220 as well as possibly by a variable pretension of the spring straps 120 nearly any desired response characteristic (characteristic line) of the spring is system made up of two spring elements 120, 220 connected in series can be achieved when an external force, for example the weight force of the user, acts upon it. In addition, by a corresponding selection of the spring constants of the spring straps 120-1 to 120-3 various comfort zones 130-1 to 130-4 can be created in the mattress base 130, which comfort zones support different body parts of the user, such as hip, loin and shoulder, for example, to a different degree and thus allow for these body parts to sink in to different depths in the actual mattress.
Furthermore, the deformation direction of the spring straps 120 and the defor mation direction of the coil springs 220 are preferably oriented essentially in the same direction relative to each other with an angular deviation of less than 200,
preferably less than 10°, or particularly preferably less than 5°.
Although the present invention has been described above on the basis of a pre ferred exemplary embodiment, the invention is not limited thereto but can be modified in various ways. In particular, the present invention can be altered or modified in various ways without deviating from the essence of the invention. The described configurations and further modifications can be combined in any manner desired.
In addition, it should be noted that "comprising" and "including " do not exclude any other elements or steps and that "one" does not exclude a plurality.
