The invention relates to a lying surface device for a bed, in particular for a hospital and / or nursing bed, or the like decking slab, with a fixed frame and a lying therefrom lying surface for receiving a mattress, a cushion element or the like, which comprises a plurality of relatively slidable Liegeflachensegmenten has, and with a drive device which is arranged frontally between two adjacent Liegeflachensegmenten

A lying surface device of the aforementioned type is known from DE 20 2006 018 156 U1 The bed surface device known from DE 20 2006 018 156 U1 has a lying surface with, for example, four lying surface segments. Accordingly, a seat section can be pivoted as the first lying surface segment, and a seat section can be pivoted as a second lying surface segment A five-part design of the mattress is also common practice, in which case the head section is divided again and a head section on the one hand and a On the other hand, the back portion is formed, wherein the head portion is arranged hingedly on the jerk portion The Liegeflachensegment serving as Gesgeflachensegment of the prior art Liegeflacheneinπchtung is fixed in position on the fixed frame The lying as a head portion Liegeflachensegment can be pivoted relative to the Liegeflachensegment serving as Gesaßabschnitt, which is advantageously carried out by an electric motor, for what purpose the end face between the Liegeflachensegment serving as Gesaßabschnitt The lying as a thigh section serving Liegeflachensegment is coupled in the same way to serving as Gesaßabschnitt segment Liegeflachensegment serving as a thigh section is in turn coupled to the serving as a foot section Liegeflachensegment, wherein for a Adjustment of serving as foot section Liegeflachensegments compared to the thigh Abs serving chute mattress segment also a drive device is provided, which is arranged frontally between these two Liegeflacheπsegmeπten

The above-described and previously known from DE 20 2006 018 156 U1 construction of a lying surface device has preserved everyday practical use A particular advantage of this prior art lying surface device is that a comprehensive Verstellmoglichkeit is created with respect to the lying surface, which allows a user, in a simple and comfortable way to be able to adjust an individual sitting and / or reclining position

The object of the invention is to develop the bedding device previously known from DE 20 2006 018 156 U1 in an alternative embodiment

The solution to this problem is achieved in that a Liegeflachensegment serving as Gesaßflache Liegeflachensegment is arranged in the longitudinal direction of the fixed frame slidably on this, wherein serving as a head portion of the mattress Liegeflachensegment is forcibly guided by means of a coupling device relative to the fixed frame

In contrast to the construction according to DE 20 2006 018 156 U1, the lying-flat segment serving as a buttock section is not fixed in its relative position with respect to the fixed frame. According to the invention, it is rather a displaceable one Arrangement provided so that serving as Gesaßabschnitt lying surface element and thus the entire lying surface in the longitudinal direction of the fixed frame is arranged relative to this, the lying surface so in the longitudinal direction of the fixed frame relative to this can be moved

The slidable arrangement of the lying surface relative to the fixed frame in the longitudinal direction of the same can be achieved, for example, in that the serving as Gesaßflache Liegeflachensegment segment carrying displacement means that with respect to a transverse extent of the lying surface left and right sides of the as a seat portion of the Sliding skids, for example, can be used as displacement means. It can also be provided that the displacement means have carrying rollers

In the final assembled state, the serving on the serving as Gesaßflache Liegeflachensegment Liegeflachensegment arranged engaging in corresponding thereto trained grooves of the fixed frame, whereby they are guided accordingly In this way, a slow-moving storage serving as Gesaßflache Liegeflachensegmentes and thus the entire bed surface opposite reached the fixed frame

The grooves receiving the displacement means can be closed end-to-end with respect to their longitudinal extension, thus ensuring that the lying-flat segment serving as the butt section of the lying surface is not unintentionally moved too far relative to the stationary frame

According to a further feature of the invention it is provided that the Liegeflachensegment serving as Kopfabschπitt the lying surface is positively guided by a coupling device relative to the fixed frame This coupling device has at least one coupling element, which according to a further feature of the invention stabformig and / or designed in the manner of a support This coupling element is, on the one hand, pivotable on the stationary frame and, on the other hand, pivotally arranged on the lying surface segment serving as the head section of the lying surface. The lying surface should consist of more than four lying surface segments and be provided for serving as a head section in a four-part design Liegeflachensegment subdivided again and is divided into serving as a head portion Liegeflachensegment and serving as a jumper portion Liegeflachensegment, the coupling element according to an alternative embodiment of the invention may also be arranged on the front side of serving as a head portion of the mattress Liegeflachensegments drive means, ie at the drive means the is provided on the end face between the lying surface segment serving as a head section on the one hand and the lying surface segment serving as a jumper section on the other hand

The längsverschiebliche arrangement of Liegeflachensegments serving as Gesaßflachensegments on the fixed frame in combination with the effect caused by the coupling Zwangsfuhrung serving as a head portion Liegeflachensegments relative to the fixed frame causes the positive effect that relative to serving as a seat portion Liegeflachensegts at a pivoting movement of the head portion serving Liegeflachensegmeπts This Nachrucken takes place at a pivoting of serving as a head portion Liegeflachensegments in the erection direction, ie at a Hochverschwenken When a down pivoting of the. as a lying portion serving Liegeflachensegge Liegeflachensegge and serving the entire lying surface relative to the fixed frame Head section serving Liegeflachensegments relative to serving as Gesaßabschnitt The lying-flat segment, thanks to its slow-moving arrangement, moves the entire lying surface back relative to the fixed frame back to its starting position, ie back towards the lying-flat segment

The automatic co-method of lying surface in the longitudinal direction of the fixed frame at a pivoting of serving as a head portion Liegeflachensegments relative to the Liegeflachensegge serving as Gesaßflachensegments has the advantage that the bed of the invention Liegeflacheneinrichtung sidelines Einrichtungsgegenstande, such as side tables, storage facilities, lighting equipment and the like a user regardless of the pivoting position of serving as a head section Liegeflachensegments are always equally well reached in a high-speed as In the case of a folding back of the lying-flat segment serving as the head section, the lying surface moves back, ie in the direction of the lying surface segment serving as a foot section, a lying surface element serving as the head section from the pivoting position of the lying surface segment serving as a head section good accessibility of a bed equipped with the invention Liegeflacheneinrichtung sibling institutions, such as furniture in the form of side tables, chairs and / or the like is guaranteed

The displaceable arrangement of a lying surface relative to a fixed frame is not unknown in the prior art. Such a displaceable arrangement is known, for example, from EP 0 678 261 A1. The construction described here, however, proves to be extremely complicated and susceptible to interference with respect to the design according to the invention According to the design of EP 0 678 261 A1, so-called intermediate links are used, by which both a pivoting movement and a movement is effected, which are thus driven by a motor This makes a costly, expansively large and be designed below the bed surface engine assembly required Remaining for a durable functional preservation of a very robust design, which makes the construction overall bulky and heavy The previously known from EP 0678261 A1 construction proves not least also from safety-relevant aspects as disadvantageous, since the measures provided for the motor control of the intermediate link assembly represent a significant risk of injury due to clamping and / or crushing

In contrast to EP 0 678 261 A1, the embodiment according to the invention takes a completely different route. The coupling mechanism used to achieve the forced guidance does not serve to cause a pivoting movement of the lying-flat segment serving as the head section. Such a pivoting movement is instead initiated by the drive device, which is located between the front side The coupling device is also not powered by a motor. It merely serves as a kind of spacer, and ensures that a pivoting movement initiated by the lying-flat segment serving as a head section initiates an automatic movement the entire lying surface leads, because the bed segment serving as a head section is always aligned at a predetermined, ie fixed distance to the fixed frame due to the Zwangsfuhrung caused by the coupling device It requires insofar advantageously in relation to the construction according to EP 0678261 A1 no special, In particular, no motor control of the coupling device, which is why the inventive construction is less complicated and easier to handle overall Moreover, the inventive construction in a simple manner allows retrofitting

1 shows, in a diagrammatically perspective view, a lying surface device 1 according to the invention, which has a lying surface 2, which is received by a stationary frame 3

The fixed frame 3 is formed by two transverse bars 4 and two longitudinal bars 5, which are coupled together by connectors 6. The transverse bars 4 and the longitudinal bars 5 are preferably formed from an extruded aluminum profile. The connectors 6 may preferably be plastic parts The lying surface 2 is subdivided into couch surface segments and has a lying surface segment 7 serving as a head section, a lying surface segment 8 serving as a butt section, a lying surface segment 9 serving as a thigh section and a lying surface segment 10 serving as a foot section

Each of the lying surface segments 7 to 10 has in each case a frame 14 which, depending on the size, carries a plurality of slats 15 arranged one behind the other in the longitudinal direction 22. Each frame 14 consists of two transverse struts 11 and two longitudinal struts 12 which are connected to one another via corresponding connectors 13 The transverse bars 11 and the longitudinal bars 12, like the transverse bars 4 and the longitudinal bars 5, can be formed from aluminum profiles. The corner connectors 13 are preferably plastic parts

The lying surface segments 7 to 10 are arranged pivotable relative to each other, for which purpose drive means 16, 17 and 18 are provided

The sleeping area segment 7 serving as the head section is pivotably arranged relative to the lying area segment 8 serving as seating portion, the drive unit 16 being arranged on the end side between the lying area segment 7 and the lying area segment 8. The lying area segment 9 serving as a thigh portion is in the same way applied to the lying area segment 8 serving as the butt section coupled, wherein between these two Liegeflachensegmenten 8 and 9, the drive means 17 is arranged serving as foot section Liegeflachensegment 10 is relatively pivotable relative to serving as thigh section Liegeflachensegment 9, for which purpose the drive means 18 is provided, between these two Liegeflachensegmenten 9 and 10th is arranged

Serving as a seat portion Liegeflachensegment 8 is slidably disposed in the longitudinal direction 22 of the fixed frame 3 to this purpose For this purpose, it is provided that the Liegeflachensegment serving as Gesaßflachensegment 8 carries displacement means with respect to the transverse extent 28 of the lying surface 2 hnks- as the right side of the lying surface segment 8 are arranged. The detail representation according to FIG. 4 allows this embodiment to be recognized As a possible displacement means Fig 4 shows a support pin 24 carried by a support roller 23 which is arranged on the longitudinal beam 12 serving as Gesaßabschnitt Liegeflachensegmentes 8. In the final assembled state, the support roller 23 engages in a groove 25 which is provided by a longitudinal spar 5 of the fixed frame 3 The carrying roller 23 is guided in this groove 25, which allows a longitudinal displacement of the Liegeflachensegments serving as Gesaßflachensegments 8 and thus the entire deck surface 2 relative to the fixed frame 3 For a position-safe and stable leadership of the mattress 2 with respect to the fixed frame 3 are preferably two, three or even more idlers 23 per üegeflachenseite 2 provided

For simple equipment of Liegeflachensegments serving as Gesaßflachensegments 8 with displacement means in the form of, for example support rollers 23 may be provided as a holder rail elements Such a rail element is preferably formed of plastic and can be arranged as part of a retrofit in a simple way on Gesaßabschnitt 8 In the final assembled state is a Gesaßabschnitt 8 equipped with two such rail elements, with a rail element with respect to the transverse extension 28 of the lying surface 2 on the left side and a second rail element is arranged on the right side of the Gesaßabschnittes 8 The connection of the rail elements and the Gesaßabschnitt 8 can be done for example by means of screwing

Two support roller bearings can be provided for each rail element, with each support roller bearing serving to support two support rollers. Preferably, with respect to the longitudinal direction 22, a support roller bearing equipped with two support rollers is on the end of a rail element and a second one For the purpose of easy assembly and disassembly, the support roller bearings are releasably connected to the rail element, for example by screwing Especially in case of repair can be easily replaced support rollers 23 In particular, wear-related wear can thus easily account be worn

The sleeping area segment 7 serving as a head section is by means of a coupling device 27 forced against the fixed frame 3. In the illustrated embodiment, the coupling device 27 has two rod-shaped coupling elements 26, which are each arranged at one end on the fixed frame 3 and the other end on the serving as a head portion lying surface segment 7 articulated. In the simplest case, such an articulated arrangement can be achieved in that the coupling element 26 has a bearing eye at one end and at the other end, which in the final assembled state is penetrated by a screw which is anchored to the stationary bed frame 3 or to the lying surface segment 7 serving as the head section ,

The construction shown by way of example in FIGS. 1, 2 and 3 has a lying surface which is subdivided into four lying surface segments 7, 8, 9 and 10. It goes without saying that the embodiment according to the invention can also be used in lying surface constructions which has more or less lying surface segments. In practice, in particular a four-part and a five-part design are used. In a five-part embodiment, the lying surface segment 7 shown in the figures with reference to a four-part embodiment is subdivided into two subregions, which can be referred to as the head or neck section on the one hand and the back section on the other hand. These lying surface segments are also designed to be adjustable relative to one another, wherein a separate drive means is provided, which is arranged frontally between these two segments. A five-part embodiment thus consists of a head or neck portion, a back portion, a buttock, a thigh portion and a foot portion.

The positive guidance of a five-part lying surface relative to the fixed frame 3 can also be formed as an alternative to the above-described embodiment in that the motor arranged between the head or neck portion and back portion is forcibly guided by means of a coupling device 27 relative to the fixed frame 3. A drive of the coupling device by the engine does not take place. The motor or its housing serves only as mitverschwenkendes pivoting component of the lying surface 2, which serves the articulation of the coupling device 27. This alternative embodiment in the case of a five-part lying surface has the advantage that can be created by structurally simple measures on the motor housing pivot points for connection to the coupling device 27. An assembly or disassembly of Coupling device 27 is simplified so. It is important to emphasize in this context that the engine does not serve as a drive device for the coupling device 27. On the drive side, it is the sole purpose of the motor to pivot the neck or head section relative to the back section. With regard to the coupling device 27, the motor or its housing serves merely as a lying surface component for the articulated arrangement of the coupling device 27, so as to create a spacer between bed surface 2 on the one hand and fixed frame 3 on the other hand in the manner described above.

5 shows a drive device, namely the drive element 16, which is arranged between the lying surface segment 7 serving as the head section and the lying surface segment 8 serving as the seat section. This has a housing 19 and shaft sections 29. The housing 19 serves to receive drive elements, such as For example, a motor, a gear and / or the like. The shaft portions 29 each comprise two half-waves, one of which carries a flange 20 and the other a flange 21. The half shafts carrying the flanges 20 are designed to be stationary, whereas the half shafts carrying the flanges 21 are designed to be rotatable by motoring. The flanges 20 are used for connection to the lying area formed as a buttocks segment 8 by the longitudinal beams 12 of this lying surface segment 8 are end-mounted on the respective associated flanges 20. For coupling the serving as a head portion lying surface segment 7 are the flanges 21, on which the longitudinal members 12 of the lying surface element 7 are aufzustecken. In the final assembled state, pivoting of the lying surface segment 7 serving as the head section is achieved by means of a twisting movement of the half shafts carrying the flanges 21 in relation to the lying surface segment 8 serving as a seat section.

The coupling elements 26 of the coupling device 27 serve as a kind of spacer and ensure that in the case of a pivoting movement of the lying surface segment 7 initiated by the drive device 16 relative to the lying surface segment 8, a movement of the lying surface 2 displaceable over the lying surface segment 8 on the fixed frame 3 takes place. This effect is most clearly evident from FIG. 3.
