Abstract

The bed surface has an upper padded body (9) and at least two parallel upper and lower slats (6, 7) placed on longitudinally extending elastic bodies (3,4), with the lower slat (7) resting on a further lower padded body (8) which in turn rests on a supp plate (25) to at least partly cover same. The distance between the slats of the upper frame and those of the lower frame is variable, seen over the length of the bed surface.

Description

Such lying surfaces with slatted frames are known from the inventor's own applications. The subject of these applications is a spring body, which consists of longitudinally extending, bar-shaped elastic bodies, which form an upper and a lower contact surface for an upper and a lower slatted frame. Each slatted frame consists of relatively thin and fine slats, which are joined relatively close together in order to achieve a very elastic lying surface with good punctiform adaptation to the body lying on it. It is known to place this spring body with the upper and lower slatted frames directly on two parallel support strips which are attached to the side surfaces of a bed frame. This design has proven itself well, because in particular the lower slatted frame can swing freely between the support strips, which are at a distance from one another, and so there is a good counter pressure and a good compensation.
However, such a construction is not suitable for certain bed constructions.

When it comes to such a spring body on a continuous Place the support surface, then it is no longer possible for the lower one Lamellar grate unfolds its vibrations and it then becomes flat on the Support surface is on and can no longer swing. This leads to overall the effect of the spring body wears off very strongly, and one out of one Spring-formed bed surface is therefore no longer suitable, a cheap Ensure support of the user's body during sleep.

DE 43 02 778 A (Längle) describes this as a state of the art for a lying surface for beds, sofas and the like with air supply. In this publication a Lying area described in which the air distribution between longitudinal and transverse running air hoses can be adjusted individually, the Air is supplied via an air reservoir in the foot area. However, there is the disadvantage that the spring or damping effect of the air hose layer is distributed over a large area. There are two to support the cushioning Slat layers incorporated in the mattress, which also has a between them Has arrangement of air hoses. The damping effect depends essentially from the air pressure in the air chambers by means of a complex device is regulated.

In DE G 87 07 712.4 (textile factory Peter Lonsberg) there is seating or reclining furniture described with a mattress which has layers of spring wood slats. These spring wooden slats are arranged in the mattress so that they are each for Are curved top and bottom. This makes the mattress work when loaded to a high degree only downwards, since they are upper and lower Spring slats are not connected.

Another document, WO 96/28072 (Studio Hüsler), discloses one Slatted frame for reclining or seating furniture with which individual slats can be exchanged as required are. However, this is a grate and not a mattress.

The invention is therefore based on the object of a lying surface with parallel arranged to each other, each extending in the longitudinal direction To further develop elastic bodies placed on the lower and upper slatted frames, that such a lying surface also on essentially continuous, full-surface contact surfaces can be used advantageously.

To achieve the object, the invention is through the technical teaching of Claim 1 marked.

An essential feature of the invention is that according to the invention the lower one Slatted frame rests on another lower cushion body, which The cushion body in turn rests on the support plate and at least partially covered this.

With the given technical teaching, the main advantage is achieved that now the swinging and bending, especially the lower part of the Louvre grille, achieved by placing it on a lower cushion body rests and this cushion body itself on the support surface for the entire Lying surface rests and partially or completely covers this lying surface.

It is now possible for the first time to use continuous contact surfaces like the one they have are known in particular in Anglo-Saxon countries and under the name "Bed-BOX" are distributed. Here it is now possible for the first time, an excellent one Adaptation of a body to a lying surface by the invention To achieve construction. First, it is provided that above the upper Slat grate is arranged a first, upper cushion body, which is already the Body weight of the sleeper takes up relatively evenly and on the upper Lamellar rust transmits.

This upper slat grate will be in the specific, highly stressed places bend, but in the other places where there is no high contact force, there is a back pressure, d. H. in other areas, the slats press down above, towards the body. This leads to an excellent one Adaptation to the body contour, because the lamellae of the upper lamella grid probably bend down as well as the body lying on it accommodate and create a back pressure.

So the body has places where it needs support from below and it has Places where a lowering is needed. The lowering is here in the buttocks area, where Experiments have shown that the slats are down in this area bend, also in the shoulder area, while in the lumbar region The lamellas of the upper lamellar grate convexly upwards and the Body meet and the upper cushion body facing upwards, convex shape so that the body is preferably supported here.

The mechanical effect on the upper slatted frame is due to the mechanical The effect of the lower slatted frame is supplemented and expanded. Would only be one upper slatted frame present, then all slats of the upper would Only lower the slatted grate downwards, which makes it effective There is no body support.

Here the lower slatted frame intervenes, the one over which between the upper and lower slatted frame located elastic body, with the upper contact force of the Body is loaded and also its slats in the appropriate places deflects either convex upwards or concave downwards. It was found that the upper and lower slatted frames are essentially always move synchronously, d. H. in the places where the upper slatted frame the lower slatted frame also turns concave arch down. To make this curvature possible, the lower one is Upholstered body provided, in the material of which the lower slatted frame or the lower slatted frame partially bends in the openings bends in there and experiences a corresponding counterforce.

It is preferred if the distance between the lamellae of the upper one Slatted frame and the lower slatted frame, over the length of the lying surface seen, is different.

If you look at the lying area in three areas from 25% - 50% - 25% lengthways divided, then it is preferred if the lamellae in the area with 25% have a greater mutual distance from one another than the lamellae in the middle 50% range. Here, too, the counterforce on the body significantly improved and increased.

It was previously stated that an essential mechanism of action of the Swinging of the upper and lower slatted frame consists in that the lower Slatted grating in the lower upholstery itself or partially in the openings of the lower cushion body swings in and there a corresponding counterforce experiences.

Of course, the invention is not based on the arrangement of two to each other parallel slatted frames limited. It is based on its own U.S. Patent 5,553,338 referred to the inventor of the same arrangement with three of each other has created spaced slat gratings and this embodiment is intended as Full reference of the disclosure content of the present invention be grasped. However, there is only the interaction of three slatted frames shown, which form a spring body in the sense of the invention. This publication however, does not teach how to make such a spring body on a substantially continuous contact surface and still the optimal suspension properties maintains this spring body.

However, the invention is not only based on the laying on of the entire lying surface a continuous contact area is limited, but it is in a training the invention provided that the entire lying area with its lower Upholstery body placed only on two spaced support strips which are attached to the long sides of a bed frame. Here too then ensured that the lower cushion body together with that on it lying and with the lower slatted frame lying freely between them Support strips can swing.

Another significant advantage of the invention is that in addition to lower cushion body also has a symmetrical upper cushion body that points to the upper slatted frame rests. So it is one with respect to a longitudinal center plane perfectly mirror-symmetrical arrangement of the lying surface available, it allows that the entire lying surface can be rotated by 180 °, so that the upper cushion body comes to lie down and the lower cushion body to above forms the contact surface for the human body.

It can be provided that the mechanical density of the upper Upholstery body and the lower upholstery body differ from each other, so that, for. B. the upper cushion body is harder than the lower cushion body, so when turning to create mattresses of different hardness for the mattress.

In a development of the invention it can be provided that both the upper Upholstery body as well as the lower upholstery body of additional Insulating fleece plates are covered, which the upholstery body up and complete below. Such a nonwoven insulating panel consists, for. B. from a Virgin wool, made of coconut fiber or the like and has the purpose of better To achieve moisture absorption and improved thermal insulation.

By arranging a central lamella construction consisting of two spaced-apart slatted gratings, an air space between them form, a favorable pumping effect is achieved. This will make the Ventilation of the entire lying area significantly improved. So after one medium air space is present, which is up through the upper slatted frame and bounded below by the lower slatted frame, each leads Body movement of the sleeper to densify the upper and lower Upholstered body into said cavity, and this leads to a Compression and expansion of the enclosed air volume, see above that this volume of air through both the upper cushion body and the lower cushion body can pass through. The result is an excellent one Ventilation of the lying surface. The used and moisturized air in the upholstered bodies and, if necessary, in the insulating fleece panels is by said Pumping effect transported to the outside in a favorable manner.

Due to the good adaptability of the lying surface due to the used fine slatted gratings on the body contour, such a lying surface also preferably used for substructures that are electromechanically adjustable. For example, the head part or the foot part can be very sensitively electromotive be raised and the entire lying surface adapts to this adjustment movement very sensitive to.

So the entire construction consists of upper and lower insulating fleece panels, the respectively on upper and lower contact surfaces of the upper and lower Rest the upholstered body. Between the upper and lower upholstery is the said spring body arranged. This consists of the above mentioned and lower slatted frames that extend on middle, longitudinally Lie on elastic bodies. It does not matter how many elastic bodies over the Width of the lying surface can be used distributed. It can be narrow Lying surfaces only two elastic bodies are used, each on the edge are arranged. With wide bed surfaces, three or four elastic bodies can be used parallel and at a distance from each other over the entire length of the lying surface extend and the contact surface for the upper slatted frame and the Form a footprint for the lower slatted frame.

Likewise, the height and the composition of the elastic bodies play only one minor role. It is preferred that the elastic body from one Natural latex material exist.

The entire structure is preferably in a, enveloping the entire structure, Cover inserted, this covering, for example, with a Open and close the zipper.

However, since it is a relatively tall structure consisting of the upper one Insulating fleece plate, the upper cushion body, the middle spring body, the lower cushion body and the lower insulating fleece plate, it is in one Development of the invention provided that three layers of this structure interconnecting cloth tabs are interconnected.

The upper layer is the upper cushion body with the one on top Insulating fleece plate referred to as the middle layer, the previously mentioned Is called spring body and the lower layer of the lower cushion body with the lower insulating fleece plate is called.

It is now provided that the lower layer is fastened with a cloth surface, which surface of the cloth is in the direction of the central spring body in the form of a tunnel-shaped cloth flap continues, and this cloth flap is across the width of the Lying area closed. Then in this self-contained cloth flap the middle spring body inserted.

The same applies to the attachment of the upper layer to the middle spring body. Here, too, the top layer is firmly connected with a cloth flap and this The cloth flap extends with its cavity over the middle spring body and this middle spring body is inserted into the cloth flap. The way is solvable both the top layer with the middle spring body and the bottom layer connected to the middle spring body via cloth flaps.

Through these cloth tabs described, the lateral stability of the whole Lying area significantly improved, d. H. it cannot move sideways as much.

Of course, it can also be provided that a total of all three layers enclosing cloth flap.

Such cloth tabs can spread over the entire period Arrange the length of the lying surface evenly.

The subject matter of the present invention results not only from the Subject of the individual claims, but also from the combination of individual claims among themselves.

All information disclosed in the documentation, including the summary and features, in particular the spatial depicted in the drawings Education are claimed as essential to the invention, insofar as they are used individually or in Combination are new compared to the prior art.

In the following, the invention will be explained using only one embodiment illustrative drawings explained in more detail. Here go from the drawings and their description further features and advantages of the invention essential Invention.

In Figures 1 and 2, a central spring body 1 is shown schematically, which in consists essentially of an upper slatted frame and a parallel one and there is a spaced-apart slatted frame 7. Both Slatted gratings consist of relatively thin slats that are parallel on the sides elastic bodies 2, 3, 4 arranged to each other are placed. To hold the Slats of the individual slatted frames 6, 7 are (not shown) on the Elastic bodies sewn tabs into which the end faces of the respective Slatted frames 6, 7 are inserted.

Between the upper and lower slatted frames 6, 7 thus form between the elastic bodies 2, 3, 4 in the longitudinal direction through the lying surface, with Air filled cavities 5.

The entire middle spring body rests on a lower cushion body 8 and is covered by an upper cushion body 9.

Figures 1 and 2 also show that the upper cushion body 9 of a upper insulating fleece plate 10 can be covered, while the lower cushion body 8th can rest on a lower insulating fleece plate 11.

Figure 2 shows schematically that the entire bed area of one Enclosure 12 can be enclosed, which completely covers the lying surface concludes. Such a wrapper 12 can be a zipper or other Have opening means.

3 shows further details, where it can be seen that a lower cloth flap 13 is intended to consist of the lower layer lower cushion body 8 and the insulating fleece plate 11 with the central spring body 1 connect to.

For this purpose, it is provided that a lower surface 14 of the cloth flap 13 on the Surface of the lower cushion body 8 is attached. Such an attachment z. B. by sewing or gluing. This lower surface 14 sits in one perpendicular to it angled end face 15, which on the end face of the Spring body 1 extends along and then in turn at a vertical angle the upper surface 16 merges, which encloses the spring body 1 from above. This end face 15 is also present on the other side, so that one in closed cloth flap 13 is formed, in the cavity of the middle Spring body 1 is inserted.

The upper layer, consisting of the upper cushion body 9 and the upper insulating fleece plate 10. Here would be at Underside of the upper cushion body, the previously mentioned surface of a cloth flap attached, and this cloth tab in turn forms a cavity through which the middle spring body 1 is inserted.

In this way, both the upper and the lower layer are connected to the middle spring body 1 by means of cloth tabs.
FIGS. 3 and 4 also show that an outer covering can be present, which can be opened by a zipper 17.

In comparison to FIG. 3, FIG. 4 shows a modified exemplary embodiment, where It can be seen that two cloth flaps 18 arranged at a distance from one another available.

Here, the two cloth tabs are designed so that a lower surface 19 of the Cloth flap 18 is attached to the underside of the lower cushion body 8 and the End wall 20 up to the surface of the upper cushion body 9, extends and there forms a continuous upper surface 21, which in turn over an end wall 20 is connected to the lower surface 19. So here is one in itself closed cloth flap 18 shown through which all three layers of Arrangement are inserted.

The biomechanical mode of action of lying surface according to the invention explained in more detail.

The body 22 resting on the upper cushion 9 exerts a contact pressure Direction of arrow 29 onto the upper slatted frame 6. This is what happens in Support area (see the general description section) for bending individual slats 23, which consequently bend downwards.

Extend other slats (not shown in the drawing) of the upper slatted frame but in the upper cushion body 9, d. H. they bend convexly above and form a corresponding counter pressure.

The same now applies to the lower slatted frame 7 and the two shown there Slats 24 ', 24 ". After the lower slatted frame 7 synchronously with the moves the upper slatted frame 6, part of the lower slats will move upwards Bend direction of arrow 29 (i.e. into cavity 5), as is the case with lamella 24 ' is shown, other slats, e.g. B. the slat 24 ", but bend in the lower cushion body 8 and resiliently lie where they are experience appropriate back pressure.

It is therefore important that the lower slatted frame 7 freely in the lower cushion body 8th can swing and the cushion body 8 itself the support of the lying surface on a continuous, relatively strong and flexurally rigid support plate 25 forms. to better ventilation in this support plate 25 holes 26 over the surface distributed.

Figure 5 shows as an alternative that the platen 25 can be omitted and that instead two or more lateral support strips 27 are present which the lower cushion body 8 is placed on the edge. These two Support strips 27 thus form a support plane 28 for the lower cushion body 8, the support plate 25 is omitted.

The present lying surface according to the invention is therefore known Spring mattresses, which rest on rigid support plates, essential think. It has a better adaptation to the body contour, a better one Dissipation of body moisture, better insulation and is above all metal-free, d. H. no metal parts or other harmful parts are contained. Namely, it has been demonstrated that the metal parts Spring mattresses lead to a distortion of the earth's magnetic field, which on the human body works, and this distortion is made perfect by the metal-free lying surface according to the invention avoided. By increasing Electrosmog in our environment leads to a coupling of the eddy currents in the metal parts of such a known spring mattress to the corresponding fields in the body, what with health problems can be connected. This becomes certain with the lying surface according to the invention avoided.
