Description

description

The invention relates to a lying surface for a bed or the like according to the preamble of claim 1.

From DE9401316U1 going back to the same applicant a lying surface for a bed is known, a number of spring-loaded plungers are attached in the side parts of the lying surface and are guided in a height-adjustable guide box arranged on the side part. A rubber-elastic tensioning cable is guided over the deflection bolts, which are arranged twice on the respective ram, which extends as a closed strand in the manner of a zigzag guide over all the rams and is attached at both ends to one side of the guide frame. It is therefore a tension rope that forms a self-contained loop.

Accordingly, the known lying surface consisted of a plurality of mutually parallel and a mutual distance occupying, bendable slats, of which at least a part of the slats rested at each end on vertically directed, spring-loaded, liftable and lowerable plungers, each in a in the longitudinal direction of the lying surface extending guide box height adjustable and spring-loaded were guided displaceably, with at least part of the plungers being held spring-loaded by the tensioning cable tensioned in the guide box under spring tension in a certain lifting position.

The disadvantage of running the tensioning rope as a closed loop in conjunction with the height-adjustable plungers was that the hardness of the bed surface was not adjustable overall because it was a self-contained strand of a tensioning rope, which in its length and degree of hardness is not was changeable.

In the case of prolonged use of such a lying surface, the tensioning cable could become fatigued and the prior art mentioned did not provide for the possibility of re-tensioning the tensioning cable and, moreover, no individual setting of the ram stroke was possible.

The tensioning cable was guided in the manner of a zigzag guide on two, a different distance from each other occupying tappet-side bolts, which was associated with the further disadvantage that the zigzag guide caused increased friction on the tappet-side bolt, whereby a low-friction lifting movement of the ram was impaired and the wear on the tensioning cable was high. Due to the fact that the bolts of the tappets which deflect the tensioning cable were arranged on the broad sides of the tappet at a mutual vertical distance, only a short stroke length and increased manufacturing costs for such double-bolt bearing tappets resulted.

The invention is therefore based on the object of developing a bed of the type mentioned so that the plunger stroke is adjustable in its hardness and also an individual setting of the plunger is given over the bed and that also a simple, low-friction and less repairable Construction is achieved ..

To solve the problem, the invention is characterized by the technical teaching of claim 1.

It is preferred if the tensioning rope is designed as an approximately straight, the guide box penetrating rope strand whose pretension is adjustable.

The known, friction-increasing zigzag guidance of the tensioning cable is thus dispensed with

A preferred feature of the invention is that the tensioning cable extends open on both sides over the longitudinal axis of the lying surface on both sides of the side part.

The tensioning cable therefore does not form a closed loop, but is guided out of the guide box openly at both ends and can therefore be retensioned at both ends.

Due to the opening on both sides of the tensioning cable, it is now possible for the first time that both the head-side and the foot-side end of the tensioning cable can be pulled out and the tensioning plug on the respective head-side and foot-side cross board is now available for the first time to tension the tensioning cable on both Adjust the ends of the guide box.

This makes it possible for the first time to individually produce the tension of the tensioning cable both on the foot side and on the head side of the lying surface, the tensioning cable being arranged separately on both the left and right side parts, so that the tensioning cables of each other parallel side parts can be individually tightened or relaxed.

At the beginning it was mentioned that there is also the possibility of individually adjusting the plunger stroke in its plunger stroke, which in a preferred embodiment takes place in that it is now possible for the first time to use the fixed pulleys, which are each arranged in the side part guide housing, to remove so that the supported length of the tensioning rope can be changed by the rotatable but immovable deflection pulleys in the guide housing and some or more fixed deflection pulleys can be removed.

Thus, the bridged length of the tensioning cable in the guide box is greater at this point and the tensioning cable is softer at this point because it can bend more because of the lack of support.

In this way, it is possible to preload the plunger resting on the tensioning cable in this area with a lower spring force of the tensioning cable, whereby the plunger stroke experiences a reduced counterforce in this area

and the lying surface, which is formed by the mattress on top, is made softer at this point. In this way, individual lying areas of different hardness can be created on the lying surface.

In another embodiment, it is provided that the guide box-side guide rollers are interchangeable. They can be exchanged for pulleys with different diameters. If the deflection pulleys with a large diameter are exchanged for deflection pulleys with a smaller diameter at certain points, the tensioning rope also becomes softer at this point, but not as soft as if the deflection pulley is completely removed at this point.

Another disadvantage of the prior art was that although there was a ball-and-socket joint mounting of the respective slat, which is shown for example in FIG. 15 of the cited publication, the ball-and-socket joint mounting did not offer the possibility of the slat being in two mutually perpendicular positions Levels turned. The ball head bearing was only intended for a pivoting movement of the staff around the vertically standing ball head, which had the disadvantage that it was not possible to rotate the staff around a longitudinal axis of the staff.

Thus, the feeling of lying is greatly impaired, because the slats did not lie with their surface completely on the contoured body surface of the user, it being assumed that a mattress or a mattress in a known manner between the slat surface and the body surface of the user other suitable support is arranged.

Thus, the feeling of lying was impaired and the body contour could not be reproduced exactly.

Another disadvantage of the known lying surface was that the slats themselves had insufficient resilience, because they were fully formed and unprotected, which was associated with the disadvantage that only the resilience of the slat could be used over its full length . A slotted lath that was designed as a single or double lath with several longitudinal slots, however, was not known.

It is therefore preferred according to an independent inventive concept if two or three independent lath segments are now formed by the attachment of transverse slots lying in two mutually perpendicular planes from the known, simple continuous lath, which allow an even better individual adaptation to the body contour .

All claims directed to the formation of the slats should enjoy protection not only on their own but also in combination with the other claims, which are directed to the tensioning cable and the tappet.

In this embodiment, it is provided that a double slat consists of at least two horizontally adjacent slat parts and each slat part is divided by a longitudinal slot extending in a horizontal plane and thereby an upper top slat and a lower slat arranged in alignment therebelow, which is through the Longitudinal slot are vertically spaced from one another.

In a further development it can be provided that at least the top batten is subdivided again by a longitudinal slot.

In addition to a double-slotted lath, which has a horizontal continuous first slot and a second vertical slot passing through the upper lath, it is possible to also slit the lath four times, whereby the lower lath is divided by a longitudinal slot, whereby a Four-fold slotted spring element results, which enables a particularly good adaptation of the slat to the body contour.

According to a further feature of the invention, it is preferred if each longitudinal spar of the lying surface is foldable with its two mutually parallel side parts, which means that, for example, in a preferred embodiment, each side part is divided by parts of 1/3 of the total length and thus a side part is divided into a total of three interconnected side sections, wherein the side sections can be connected to one another by means of suitable connectors. In this embodiment, it is also preferred that the tensioning cable remains in its assembly position, so that the tensioning strap remains in its assembly and tensioning position even when the side parts are folded.

According to a further preferred feature of the invention, it is provided that, compared to the construction of DE9401316U1, the double deflection bolts known there for the zigzag guidance of the tensioning cable are replaced by a single, profiled on the circumference, tappet foot-side pressure roller and this pressure roller rests on the tensioning cable. With the same length of the ram, an extended stroke of the ram on the tensioning cable is achieved.

Furthermore, an increased stroke of the plunger is achieved in that the plunger can dip through suitable recesses in the bottom of the guide box, which leads to a significantly larger stroke of the plunger with the same size of the guide box. For example, it is thus possible for the first time to enable a spring-loaded stroke of more than 100 mm for such plungers, while the prior art only allowed a plunger stroke of 70 mm.

The invention is not limited to a slide stroke of 100 mm or more. In preferred refinements, 150 mm can also be achieved.

Another feature of the invention over the prior art is that both the fixed pressure rollers, which are rotatable, detachable and pluggable in the guide box, and also the foot-side pressure rollers pluggably attached to the plungers are now designed as rollers, while the Prior art such roles were missing and only socket pins were available.

The use of pressure rollers as a replacement for known socket pins has the advantage that the tensioning cable, which is guided over both the plunger-side rollers and the fixed rollers, is now easily and smoothly guided over the fixed and movable rollers and thereby wear and tear on the tensioning cable is avoided, which increases the service life and the tension is evenly distributed over the length.

Another advantage is that due to the pressure roller on the side of the tappet foot, the plunger is now centered on the tensioning cable without tilting of the plunger in the guide box-side recess for the longitudinal guidance of the plunger.

A vertical ball head bearing was already described in DE9401316U1 in FIG. 15, but this ball head bearing suffered from the disadvantage that there was no protection against jumping out, which is the case with the present invention.

According to a further preferred feature of the invention it is provided that the end-side ram elements are designed as mattress holders, d. H. the pusher element in question is held immovably on the lying surface, but engages with a mattress holder in a form-fitting recess in the mattress in order to secure it against displacement on the lying surface.

Overall, it is found that the invention has significant advantages over the prior art, because the two-sided lead out of the tensioning cable from the two end faces of the guide box forming the side parts now for the first time gives the possibility of the rubber-elastic tensioning cable at the two end faces or Pull out and fix the transverse sides of the lying surface, individually adjustable in length. Due to the straight guidance of the tensioning cable, the tensioning cable is also easily exchangeable.

The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with one another.

All information and features disclosed in the documents, including the abstract, in particular the spatial configuration shown in the drawings, could be claimed as being essential to the invention, insofar as they are new, individually or in combination, compared to the prior art.

In Figure 1, the top view of a lying surface 1 is shown, which consists essentially of two parallel and mutually identical side parts 2, 3, the two side parts each connected by a head-side cross board 4 and a foot-side cross board 5 are. The connection between the side parts 2, 3 and the transverse boards 4, 5 is easily detachable and is formed, for example, by socket pins.

Furthermore, the figure 1 shows schematically that the side parts 2, 3 are divided into three and each consist of a side part 2a, 2b and 2c, said side parts in the connected state are positively connected to each other only by parting lines 6 and in themselves are completely separable, a tensioning cable 23 remaining in the interior of the side sections 2a, 2b, 2c which are separated from one another.

FIG. 1 also shows that, in the plan view, there is a longitudinal groove 10 which is continuous in the longitudinal direction on the side parts 2, 3, in which a stop damper 33, which will be described later, is inserted.

Furthermore, FIG. 1 also shows connecting bores 7, which are arranged on the side parts 2, 3 and are used to fix connection housings which are designed as plug connectors 36 and which result in the form-fitting connection.

Figure 1 also shows a plurality of plungers 8, which in the vertical direction, d. H. perpendicular to the plane of the drawing of FIG. 1, are mounted so as to be displaceable against a tensioning cable 23 in a spring-loaded manner, the tensioning cable 23 holding the plunger 8 in a raised position due to its spring force.

Only the fixed plungers 9 are to be regarded as an exception, which are arranged immovably at the corners of the respective side parts 2, 3 and form a fixed support for a lath connecting the respective opposite plunger there.

The invention is not limited to a third division of the foldable side parts 2, 3. Any other subdivision can be made, for example the side parts 2, 3 can also be halved or quartered. The representation of the division into thirds of the side parts 2, 3 is only to be understood as an example.

Figure 2 shows the advantageous structure of the side parts 2, 3 according to the invention, where it can be seen that the plungers 8 are spring-loaded adjustable in height and displaceably mounted in a guide box 14 and a pressure roller 19 is arranged in each case on the foot side of the movable plunger 8 which is centered on the round profiled tensioning cable 23 due to a groove that is incorporated there, so that tilting of the plunger 8 in the recesses in the guide box 14 is avoided. The plungers 8 run straight, play-free and noiselessly in the associated recesses of the guide box, whereby in an additional development of the invention it can be provided that felt plates 53 lining the recess can be provided in the area of the recess, which is an improved and, above all, noiseless Ensure guidance of the plunger 8 in the guide box 14.

FIG. 2 also shows an individual setting option for the various tappets 8 on the tensioning cable 23.

There it is shown that there are rotatably mounted deflection rollers 21 in the guide box, which also have annular grooves running all around, on which the tensioning cable 23 runs in a centered manner, without it being able to jump down from the respective guide box-side deflection roller 21.

Each plunger-side pressure roller 19 engages in the space between the pulleys 21 rotatably but immovably arranged in the guide box and due to this resulting tension between the spanned length of the tensioning cable 23 between the guide box-side guide rollers 21 serving as supports, the individual spring-loaded results Preload of the respective ram 8.

According to a preferred feature of the invention it is provided that individual guide box-side guide rollers 21 can be removed. As a result, according to FIG. 2, there is a greater spanned length of the tensioning cable 23 between the guide box-side deflection rollers 21 which are located apart, whereby the tappets at this point press more gently against the tensioning cable and experience a reduced counterforce. This is shown by way of example in FIG. 2 on the left-hand side with two tappets and in the middle part with three tappets, because the guide box-side pulley 21 has been removed with respect to these tappets, whereby the tensioning cable is softer at this point.

It is thus possible to form individually cushioned lying zones in the area of the mattress 11, which rests on the lying surface 1, which was previously not possible with the prior art.

FIG. 2 shows that there is the possibility of inserting the lying surface 1 as a circumferential frame in a fixed existing bed frame in order to form a lying surface there.

Figure 2 also shows that instead of inserting the lying surface 1 in a circumferential bed frame, it is now possible for the first time to arrange feet 12 on the underside of the guide box 14 in the area of the side parts 2, 3 so that the entire lying surface 1 is free and a supporting bed frame is not required.

FIG. 2 shows that, according to a further preferred feature, it is provided that the mattress 11 is held immovably on the lying surface 1 with mattress holders 13. The mattress holders 13 are rectangular blocks which engage in shape-adapted recesses in the mattress 11 and secure them against displacement both in the longitudinal and in the transverse direction.

Furthermore, FIG. 2 shows that the respective outer sides on the side parts 2, 3 are designed with fixed, non-displaceable tappets 9, which only support the mattress 11.

In a preferred embodiment of the invention it is provided that the side parts 2, 3 are each formed by a guide box 14 in which the plungers 8 press against the tensioning cable 23 with pressure rollers 19 at the foot so that they can be displaced in the vertical direction. In another embodiment it can be provided that a longitudinal spar is arranged in the guide box 14, which forms the frame of the lying surface 1. In this case, the longitudinal spar is connected to the guide box 14.

FIG. 2 shows that the tensioning cable 23 is pulled out at the end face in the area of the transverse boards 4, 5 and is connected to a tensioning plug 24 there.

It is also shown that a deflection pulley is arranged in the end face 18 on the transverse board, over which the tensioning cable is guided in order to be fixed to the respective transverse board 4, 5 in various lengths with the aid of the tensioning plug 24.

In this way it is possible for the first time to set the tension of the tensioning cable 23 on the two transverse boards 4, 5 for each side part 2, 3 separately.

FIG. 3 shows an end view of the lying surface 1 with a representation of the end wall 18 in the area of the transverse board 4 or 5.

It can be seen that the tensioning cable 23 is led out via the deflection pulleys 29 on the transverse board side and, with the aid of the aforementioned tensioning plug 24, can advantageously be inserted into a total of four different locking bores 28. The clamping pin 24 can accordingly be pulled out of the first pegging hole 28 in order to be inserted in the direction of arrow 31 into the next or the next but one pegging hole 28. In this way, there is a possibility of adjusting the tension of the tensioning cable 23 covering large adjustment ranges, which was not previously the case in the prior art.

FIG. 3 also shows that, in a first embodiment, a double slat 20 is fastened to each of the plungers 8. The double slat 20 each has a longitudinal slot 25 running in a horizontal plane, so that the longitudinal slot 25 results in two separate, vertically aligned, superimposed slat parts, namely an upper slat 20a and a lower slat 20b.

The upper batten 20a is particularly bendable through the horizontal longitudinal slot 25 when the body weight acts on the upper batten 20a in the direction of arrow 34, which when overcoming the longitudinal slot 25 only subsequently acts on the resilient lower batten 20b, which forms a resilient stop.

Furthermore, FIG. 3 shows that the double slats 20 are each rotatably mounted in a horizontal pivot bearing 35 and releasably engage in a tappet-side bearing housing 27 via associated connecting pieces 26 and are rotatably mounted there.

FIG. 3 also shows the previously mentioned stop damper 33, which is inserted in a longitudinal groove 10 on the upper side of the guide box 14.

In order to enable good accessibility of the rollers stored in the guide box 14 and to replace or remove the rollers if necessary, a locking board 32 is provided, which is slidably mounted in two mutually opposite longitudinal grooves 43 on the guide box to provide a slight To enable accessibility of the rollers 19 and 21 arranged in the guide box 14.

FIGS. 4 and 5 show the side view of the arrangement according to FIG. 2, FIG. 4 showing the view from the inside and FIG. 5 showing the view from the outside.

It can also be seen that the guide box 14 forming the side part 2 is divided into a total of three parts that can be separated from one another, namely into the side section 2a, 2b and 2c. These parts are each separated from one another by a parting line 6 and connected to one another in a form-fitting manner.

FIG. 4 shows that the parting line 6 is bridged by a plug connector 36 in the assembled state of the side sections 2a - 2c.

For this purpose, insertion holes and associated plug-in pins are provided.

The plug-in pins are shown, for example, as plug-in dowels 37 in FIG. The associated mounting holes are not shown for the sake of simple graphic description.

A guide box 14 is assigned to each side part 2, 3. Each guide box 14 consists of a cover 15 according to FIG. 6, two side walls 17 vertically adjoining the cover 15, and a bottom 16 adjoining vertically.

FIG. 6 also shows that the term double slat 20, which was used earlier, is to be understood as meaning that the double slat 20 consists of two separate slat parts 60a, 60b, the two slat parts 60a, 60b being connected to one another by a bearing housing 27 are connected, the two slat parts 60a, 60b forming a free space 64 between them which enables the two slat parts 60a, 60b to rotate and tilt individually about a horizontal longitudinal axis. You can therefore rotate and tilt around the socket pins that have been drawn in by 360 ° in the bearing housing 27 in order to optimally adapt to a body contour.

FIG. 6 also shows that the slat parts 60a, 60b each have rounded rounded edges 61, which are also shown in the subsequent drawings.

It can also be seen from FIG. 6 that the plungers 8 with the pressure rollers 19 arranged on the foot side can be displaced through associated guide box-side slide guides 40 and can be pushed out of the base 16, as is shown, for example, with reference to FIG.

FIG. 6 also shows that the front side of the guide box is provided with associated plug-in dowels 37 so that the guide box parts, which are preferably divided into three, can be plugged together.

Figures 7 and 8 show the top and bottom view of a guide box 14, wherein in the top view according to Figure 7 it can be seen that the plunger 8 rest with their foot-side pressure rollers 19 on the tensioning cable 23 and the tensioning cable each foot through the guide box 14 rotatably mounted, profiled pulleys 21 is guided.

It can be seen that plug-in axles 38 are provided in the area of the mutually opposite side walls 17, in which the guide box-side guide rollers 21 are mounted.

FIGS. 9 and 10 show the respective top view and bottom view in the same way as FIGS. 7 and 8, the top view of the cover 15 being shown in FIG. 9 and the top view of the bottom 16 being shown in FIG.

The same reference numerals with the same description as given above apply to the same parts.

It is also shown in FIG. 9 that the tappets 8 have plug receptacles 41 which are open at the top and into which ball joint pins 47 to be explained later are inserted.

FIG. 11 shows a section through a plunger with its plunger guide in the guide box 14, FIG. 11 showing the lowered position of the plunger under the greatest possible tension of the tensioning cable 23 'when the plunger 8' is in a lowered position in the direction of arrow 46 '(Ram stroke) is pressed against the tension of the tensioning cable 23'.

In this case, a sliding guide 40 is formed in the guide box 14 by felt plates 53 which line the sliding guide 40 in order to enable a noiseless and low-friction displacement of the plunger 8 in the sliding guide.

Figure 12 shows the raised position of the plunger 8, with a representation of the upper ball joint pin 47, which engages in a suitably adapted bearing housing 48 and is pivotably mounted there and a protection against pulling out is formed in that the bore 49 as a stepped bore is formed, in which the ball joint pin 47 engages with its ball head 65. It is secured against being pulled out by an undercut in the stepped bore.

FIGS. 13 and 14 schematically show a section through the guide box 14 with a representation of the aforementioned sliding guide 40, which is lined with felt plates 53. In the base 16 there is a longitudinal cut 42 through which the foot side of the plunger 8 can penetrate, as is shown in FIG.

It is also preferred if the sliding guide through the felt plates 53 prevent the tappet foot from tilting in the longitudinal guide, as is shown in FIG.

FIG. 14 shows that after the locking board 32, which is mounted displaceably in the mutually opposite longitudinal grooves 43, has been removed, there is free accessibility to the interior of the guide box 14.

Thus, the guide box-side fixed deflection roller 21 can be fixed by a plug-in axle 38, which is preferably designed as a socket pin and engages with its front end in a blind hole 54 and releasably mounted with the other end in the through hole 55 of one side wall 17 is.

In this way, an easily accessible bearing is formed in the interior of the guide box 14 for the deflection rollers 21 arranged there.

In Figures 15-17 further representations of the plunger 8 are shown, it being possible to see that the plunger-side pressure roller 19 is easily rotatably mounted on a plug axle 38, which is also designed as a socket pin.

It can also be seen that the pressure roller 19 is profiled in the central area and is adapted to the profile of the tensioning cable 23 in order to provide good central guidance of the plunger 8 on the tensioning cable 23.

Here, too, it is shown that the plug-in axle 38 on the tappet side is guided into a blind hole 54 and into a through hole 55.

In FIG. 17, the ball head mounting is shown as a ball joint pin 17 which can be plugged into a plug-in receptacle 41. There it can be seen that the axial displacement in the direction of the arrow 58 is prevented by an upper stop 59 and thus the plug-in axis 57 of the ball-and-socket joint pin 47 can be inserted into the plug-in receptacle 41 in the plunger.

The ball head 65 is secured against falling out in the bearing housing 48 by an undercut.

It can also be seen from FIG. 17 that a pivot bearing 25 in the manner of a socket pin is formed on the side of the bearing housing 27, in which the end face of a double slat 20 with the slat parts 60a, 60b is inserted rotatably in the arrow directions 52.

FIG. 18 shows the same illustration, but in a position rotated by 90 °, the end view of the end wall 18 of the transverse board 4, 5 being shown.

The same reference numerals apply to the same parts and it can be seen there that the clamping plug 24 can be inserted into the locking bores 28 in four different clamping positions.

FIG. 19 shows the same representation as FIG. 18, but with a representation of further details of the double slat 20, which is also shown in FIG.

While only one side surface of the double slat 20 is shown in FIG. 18, FIG. 19 shows that two double slats 20 parallel to one another are present and each double slat 20 consists of the slat parts 60a, 60b.

The slat parts 60a, 60b form a free space 64 between them, so that each slat part 60a, 60b can be individually rotated in the arrow directions 52 and are spaced apart in the horizontal plane so that the two slat parts 60a, 60b do not collide with one another during movement .

Figure 20 shows the subdivision of the side parts 2, 3, with only one side part 2 is shown in the manner of a guide housing 14, which consists of a total of three parts, which are only referred to as the side sections 2a, 2b, 2c and the are now folded to allow a shorter transport length.

The parts separated from one another by the parting lines 6 can thus be pivoted open in the arrow directions 63 and can thus be connected to one another in a form-fitting manner via the aforementioned plug connections 36. The plug-in dowels 37 shown are part of the plug-in connections 36.

FIGS. 21 and 22 show the structure of a double lath 20 which - as shown - consists of an upper lath 20a and a lower lath 20b arranged vertically below it in alignment. The two parts are separated from one another by a horizontally running, central longitudinal slot 25. Of course, in another embodiment, it is possible to choose the size and / or thickness of the top batten different from the size and / or thickness of the bottom batten.

[0107] Instead of an arrangement of the upper and lower laths lying one above the other, a lateral offset can also be provided.

FIG. 22 shows the top view of the arrangement according to FIG. 21, where it can be seen that the double slat 60 consists of the slat parts 60a and 60b and the two slat parts 60a, 60b are designed to be exactly identical to one another. They are each received in the assigned pivot bearings 35 and the socket pins arranged there in the bearing housing 27.

FIG. 23 shows a bearing housing 48 which consists of a ring separated by a slot 66. When the ball head 65 is pushed through, the ring-shaped bearing housing 48 is spread open and closed again behind the ball head in order to avoid unintentional pulling out of the ball head.

The spherical head therefore snaps with its profiled outer circumference into the likewise profiled bearing housing 48 and holds it tightly without displacement, but enables rotation in the mutually perpendicular directions of arrows 67 and 68 in the respectively indicated pivot angles 67, 68 according to FIGS.

A talc layer 50 is arranged in the bearing housing 27 in order to give the ball head permanent lubrication.

Figures 27 to 30 show an embodiment modified compared to the double slat 20 with the slat parts 60a, 60b, in which only a single slat 70 is present, which is, however, divided by a horizontally extending longitudinal slot 25 and in a first embodiment also one may have further separating slot 73 extending in a vertical plane, which divides the lath parts into two parallel lath parts, the upper lath being divided into two lath parts 70a, while the lower lath 70b is not yet divided.

In an embodiment modified therefrom, it is shown schematically that the lower slat 70b can also be divided by a vertical separating slot 74 running there and thus also forms two lower slat parts 70b on both sides of the separating slit 74.

Overall, either a triple or quadruple slotted single slat 70 is thus represented.

Of course, the present invention also provides, in a modification, that the double slat 20 shown here with the slat parts 60a, 60b is designed with triple or quadruple slits in the same way as was shown with the aid of the examples in FIGS. 27-30.

The advantage of the triple or quadruple slotted single slat 70 or the single or multiple slotted double slat 20 is that a further improvement in the individual adaptation of the respective slat parts to the body contour of the person lying on it is made possible, which would not be possible with simple, unprotected slats .

With the figure 31 a further embodiment of the lying surface 1 is shown. In FIG. 31, the double slats 20 or slat parts 60a, 60b are arranged on an eccentrically mounted pivot bearing 35. Due to the eccentric mounting of the rotary bearing 35, the center of gravity is shifted, whereby a tilting moment is achieved, the double slats 20 or slat parts 60a, 60b tilting when the torque is exceeded. This tilting movement is shown by the arrows 52. The eccentric pivot bearing enables an even more precise adaptation to the respective body shape.

With the figure 32, the tilting movement of the eccentrically mounted pivot bearing 35 is shown, the two slat parts 60a and 60b are pivoted inward into the free space 64 in the left representation, while the two slat parts 60a, 60b are pivoted outward in the right representation are pivoted.
