DESCRIPTION

Rest furniture, in particular furniture for sleeping or reclining.

The invention relates to a rest piece of furniture, in particular a piece of furniture for sleeping or reclining, according to the preamble of claim 1.

Rest furniture, particularly sleeping or reclining furniture, differs essentially based on different sleep cultures in different countries and continents. Also, the different rest furniture

10 will also depend on the use, whether in homes, hotels and hospitals, on the one hand, and in the automobile sector, on the other hand, especially in trucks, caravans and boats. As a result of the different customs of the dream and the purposes of use, the rest furniture is distinguished by its construction.

In the case of known rest furniture, the so-called bed bases are used as a spring system for

15 mattresses The bed bases have transverse oriented sheets, in particular elastic sheets mounted on a rigid frame with the help of elastic support means. The frame makes the spring system bulky and difficult to handle. Also, the frame requires frames that are adapted to it.

From WO2006 / 114554A1 it is known that the sheet support means are secured by

20 fixed or mobile way in a flexible side cord of the spring system. The support means constitute an integral component of the lateral cord or even form part of the lateral cord itself. The integral connection between the support means and the lateral cord does not allow the spring system to be individually adapted.

The invention has the objective of creating a rest furniture, in particular a sleeping or reclining furniture, which has a modular structure and can be used individually.

In order to achieve this objective, a rest furniture has the characteristics of claim 1. The fact that the spring system is at least partially configured without a frame and that a supporting means is assigned to it allows the system to be easily manipulated. spring This can be transported, for example, in a rolled-up manner. The bearing means assigned to the spring system can be individually designed, which allows it to be adapted to the respective purpose of use and to the prevailing sleep habits in each case. The carrier means may be a separate component between the support and the spring system or below the spring system. In this case, the carrier means not only serves to stabilize the spring system, but also as an adapter element to adapt the spring system to any support, specifically also to existing supports. The supporting means can also be formed by the support itself, for example, a bed frame. In addition, at least one lateral cord is assigned to each longitudinal side of the spring system. The support means, assigned to the same longitudinal side, are connected with the at least one lateral cord of each longitudinal side of the spring system. The support means and the sheets assigned to them, in particular the elastic sheets, are thus interconnected on each side of the spring system, the distances of the support means being fixed by means of the lateral cords and, therefore, also the distances of the sheets that run parallel to each other in transverse to the longitudinal direction of the rest furniture. The lateral cords serve to position all the support means. The support means are attached to the retention cords without the possibility of displacement, so that the support means and the sheets maintain their planned parallel distances from each other. These unions are

45 separately configured, which allows for easy replacement of the support means and also allows varying the amount of support means corresponding to the needs, if the distance of the sheets from each other must be varied due to a greater amount or smaller sheets. The at least one side cord is formed by a flat belt.

50 The spring system has several transverse oriented sheets, in particular elastic sheets, which run parallel to each other at a distance, elastic support means assigned to opposite ends of the sheets and flexible and non-rigid side cords, in which the means of support can be fixed. Such a spring system can be wound, because the side cords are flexible and not rigid. This allows the spring system to be transported and stored simply and with space saving. For this purpose, the side cords are

55 configured as flexible belts, cables or bands. If necessary, the flexible and non-rigid side strands can be extensible, so that it is possible to vary the length of the spring system in correspondence with the needs.

An advantageous variant of the rest furniture provides for configuring at least some support means in a manner

E10706547

09-09-2014

mobile itself or capable of oscillating. Such support means allow movements or oscillations of the spring system, in particular of its sheets or elastic sheets. The support means may be configured so as to enable or cause movements or oscillations in any direction, either only in a single desired direction or in several directions. It is preferably provided that the spring system or the sheets or sheets

5 elastic perform movements and / or oscillations only in one direction. This single direction of movement runs in particular in the longitudinal direction of the sheets or elastic sheets. Therefore, the person placed on the spring system makes movements or oscillations in the transverse direction.

A preferred variant of the rest furniture provides that the lateral cords of the spring system are attached

10 at each of its opposite ends by means of a respective rigid crossbar, for example, a bar, a slat, a board or an angular profile. In this way, the lateral cords are held together at opposite ends of the slats, in particular at a distance. The rigid transverse cords facilitate the winding of the spring system and stabilize it in the rolled state.

15 Likewise, it can be provided, if necessary, to configure the carrier means as a preferably rigid frame that stabilizes the flexible spring system during use, preferably keeping it in a plane defined by the frame. The carrier means preferably has supports for at least partial areas of the lateral cords. These supports ensure that the lateral cords rest in a fixed manner on the support means, and the support means provides the spring system with the stability that the known spring systems obtain from

20 the frames fixedly attached to them. The supporting medium can have any configuration, which allows an adaptation to different purposes of use of the spring system and to different sleep cultures. The bearing means can be formed by individual parts, in particular stringers and crossbars, from which the rigid frame is formed by separable joints. The separability of the joints allows the bearing medium to be grouped with space saving, for example, for transport.

An advantageous configuration of the invention provides that the bearing means is formed by fixed stringers with the supports for the lateral cords and that the stringers can preferably be detachably attached to the crossbars, provided at the ends of the spring system, with the in order to form a stable frame to support the spring system, in particular its lateral cords. This bearing medium has a simple construction and

30 specifically requires only two additional stringers that together with the crossbars of the spring system create the bearing means configured as a stable frame.

The rest furniture according to the invention envisages assigning the support means to the support for the spring system. The carrier medium is preferably formed by the support, so that the carrier medium is an integral part of the

The support and, therefore, the support constitutes both the supporting medium. This configuration of the invention is particularly suitable if the invention is designed together with an existing support, configured so as to be suitable for supporting or supporting the spring system, in particular the flexible side cords. In this case, the support can be an existing bed or an existing couch, in particular lower parts thereof.

A preferred configuration of the invention has the features of claim 9. The intermediate parts provided accordingly to join the sheets, in particular their ends, to the support means allow joining sheets of different cross sections to the support means. Alternatively or additionally, the intermediate pieces also serve to vary the height of the sheets above the support means. In general, the intermediate pieces serve to form an adapter element in order to allow individual bonding,

45 preferably separable, between the sheets and the support means.

The intermediate pieces are assigned to the ends of the sheets, namely, preferably so that the intermediate pieces fit over the ends of the sheets or are inserted into the ends of the hollow sheets. In this way, a traction connection is achieved between the sheets and the intermediate pieces. The pieces

50 intermediates may be configured so that it is possible to attach them to the ends of sheets having different cross sections. However, it is also possible to use different intermediate pieces that adapt respectively to the different sheets. Due to the presence of the intermediate pieces, it is possible to drag different sheets to the same support means.

In a preferred configuration of the intermediate pieces it is provided to detachably link them to the support means, preferably by insertion, interlocking or the like. These separable joints make it possible to replace the support means or also the sheets to vary the properties of the spring system, namely, to adapt them individually to the requirements, in particular to the different sleep cultures. According to another preferred configuration of the intermediate pieces, it is planned to configure them so that they join the ends of the sheets to the

E10706547

09-09-2014

Support bodies at different heights. By selecting the corresponding intermediate pieces, the height of the sheets relative to the support bodies can be varied individually. It is also possible to configure the intermediate parts so that they are elastic or flexible. Therefore, with the intermediate parts the elastic properties of the spring system can be varied.

A possible variant of the invention is that at least some intermediate parts and / or some support means are configured so as to allow movements or oscillations of the sheets, in particular of the elastic sheets. In this case it can be about movements or oscillations of a single axis or of several axes. At least some support means and / or some intermediate parts are preferably configured so that

10 allow movements or oscillations of the sheets or elastic sheets in the longitudinal direction, the person resting on the spring system moving in a transverse direction. The described variant of the invention increases the comfort of the rest furniture.

A preferred variant of the rest furniture envisages assigning at least some support means devices for

15 vary its elastic properties. These devices preferably serve to vary the elastic characteristic of the support means that will elastically support the ends of the sheets. Therefore, the elasticity behavior of the spring system can be varied individually in order to adapt to the desired habits of sleeping and resting. It is possible to configure the devices so that the elastic properties of the support means can be varied manually or also automatically. It is also possible to separate the

20 devices to selected support media. The devices can thus be specifically assigned to those support means, whose elastic properties must be modified.

According to another configuration of the invention it is possible to assign actuators at least to some support means to vary the elastic properties of these support means and / or to periodically move the spring means up and down. Such actuators can be used to stimulate the person in the rest furniture. The actuators allow to create rest furniture for therapeutic purposes.

Other advantageous configurations of the rest furniture refer to additional devices for massage and / or stimulation functions, for the generation of sound waves or light rays. It is also possible to assign 30 sensors to the mattress to measure vital parameters of the person placed on the mattress and also air conditioning systems.

It is also possible to provide the rest furniture with the so-called functional modules. In this case, it may be additional modules that are preferably arranged between the support means and the spring system or which are also integrated in the support means and / or the spring system. These functional modules are devices for adjusting the rest furniture, for example, to vary the inclination of a header and / or feet. The necessary articulations in this regard may be the object of the functional module. They can also be integrated into the supporting medium. In this way it is possible to individually configure the rest furniture and in particular also automate the spring system settings. It is also possible to retrofit

40 existing rest furniture with a functional module or individual functional elements thereof to adapt the rest furniture to the variable requirements or perfect it.

Fig. 13 a fifth embodiment of the invention in a perspective representation.

The invention is explained below by means of a rest unit, specifically a bed 10 represented in Figure 1.

Bed 10, shown in the exploded representation of Figure 1, presents (from top to bottom) a

20 bed frame 11, a supporting means configured as a supporting frame 12, a spring system 13 and a mattress 14. The bed frame 11 and the mattress 14 are configured in the usual manner, that is, they do not differ from the state of the technique.

The spring system 13 is configured in particular according to the invention, since unlike the

25 known spring systems with a rigid frame, this does not have a frame and is therefore flexible. For the stabilization of the spring system 13, the supporting frame 12 assigned thereto according to the invention is used. The spring system 13 and the supporting frame 12 together form a stable unit by serving the supporting frame 12 as a support for the flexible spring system 13 and by keeping the latter in a plane. While the supporting frame 12, shown here, runs in a straight line in the longitudinal direction 15 of the bed 10, the

The invention also comprises modifications not shown with a development, not rectilinear in the longitudinal direction 15, of the supporting frame 12, whereby the spring system 13 is fixed in the supporting frame 12 so that this non-rectilinear development follows. Thus, for example, in the case of reclining furniture, the development of the supporting frame 12 and the spring system 13, held therein, can be curved or corrugated in the longitudinal direction 15 of the bed 10. It is also possible that the supporting frame 12 runs here slightly

35 inclined up or down with respect to one end of the head side and / or one end of the side of the feet or that the ends of the side of the head and / or the feet can pivot.

The spring system 13 has several sheets 16 that run transversely to the longitudinal direction 15 of the bed 10 and which may, if necessary, be elastic sheets. The sheets 16, which run together in parallel between

40 yes, they are located at preferably uniform distances in longitudinal direction 15 of the bed 10. In the exemplary embodiment shown, the spring system 13 has eleven sheets 16. The sheets can be the same here, although it is also possible to form the system of spring 13 from different sheets, in particular sheets with different cross sections and different stiffness. Also, the amount of sheets 16 may be arbitrary, that is, it is not limited to the exemplary embodiment shown with eleven sheets 16.

In the spring system 13 shown here, on each sheet 16 several elastic bodies 17 are arranged separated from each other. The distances between adjacent elastic bodies 17 are preferably equal. In the case of the spring system 13 shown, all elastic bodies 17 in each sheet 16 are also configured equally. However, it is also possible to assign different elastic bodies 17 to sheets

50 different 16 or even provide individual sheets 16 of different elastic bodies 16. It is also possible that the sheets 16 of the spring system 13 are not provided with elastic bodies 17. The lower side of the mattress 14 then rests directly on the sheets 16. In the spring system shown 13 with elastic bodies 17 on all sheets 16, the bottom side of the mattress rests on support plates 18 of the elastic bodies

17.

55 Each sheet 16 is connected by its opposite ends 19 to a support means 21 with the help of an intermediate piece 20. The support means 21 of all the sheets 16 are interconnected with a lateral cord 23 on each of the opposite longitudinal sides 22 of the spring system 13. The ends 24 of the side cords 23 on opposite longitudinal sides 22 of the spring system 13 are joined by rigid crossbars

E10706547

09-09-2014

25 which run transversely to the longitudinal direction 15 of the bed 10. The spring system 13 therefore has two parallel crossbars 25, specifically a crossbar 25 at the end of the headboard and a second crossbar 25 at the end of the feet of the bed 10. The crossbars 25 keep the flexible side cords at a distance 23. Despite the flexible side cords 23, the sheets 16 remain in their orientation

5 parallel to each other with the aid of the support means 21 fixed without the possibility of displacement in the lateral cords 23. As a result of the flexible configuration of the lateral cords 23, the spring system 13 can be folded, in particular winding, namely , around a single axis that runs parallel to the sheets 16 and the crossbars 25.

10 In the exemplary embodiment shown, the side cords 23 are formed from flat belts. The flat sides of the straps of both side cords 23 are located in a horizontal plane in the case of the flat spring system 13 shown here. When the lateral cords 23 are formed from belts, the lateral cords 23 are not rigid and therefore unstable, that is, highly flexible, in their longitudinal direction. Instead of the straps, the side cords 23 may also be formed from one or, if necessary, several cables

15 or bands. In the exemplary embodiment shown, the cross members 25 for joining the ends 24 of the parallel lateral cords 23 on each longitudinal side 22 of the spring system 13 are configured as straight sheets or boards. These are essentially rigid unlike the side cords 23.

The support means 21 are resiliently configured, namely, so that they support the plates 16 of

20 elastically flexible way. In the bed 10 shown in Figures 1 to 3, all the support means 21 have an equal configuration, specifically according to the detailed representation in Figure 4. Accordingly, each support means 21 essentially has an oval ring 26, whose longest axis runs parallel to the longitudinal direction 15 of the bed 10, that is, is located on the longitudinal sides 22 of the spring system 13. In the center of the lower half of the ring 26 an element of lock 27 surrounding the respective

25 lateral cord in the cross-section 23. The locking element 27 has two halves, specifically an upper half 28 that constitutes a central part of the lower section of the ring 26 and a lower half 29. The lower half 29 is attached to the upper half 28 by a pivot shaft that forms a hinge. The pivot axis, not shown in the figures, runs parallel to an inner longitudinal edge of the side bead 23, on which the support means 21 is fixed. The pivotable bottom half 29 of the blocking element 27 can be joined in a manner

30 separable to the upper half 28 by a closure 30. The closure 30 is configured as a detachable interlocking closure. The blocking element 27, either the upper half 28 or the lower half 29 thereof, is provided with a shoulder not shown in the figures that engages in a corresponding depression, preferably a circular opening 31, in the lateral cord 23. When the blocking element 27 is closed, the blocking element 27, which surrounds the lateral cord 23, is fixedly dragged on the lateral cord 23. Accordingly, the support means

35 21 it is not possible to move in the longitudinal direction 15 of the bed 10 on the corresponding lateral cord 23. The lateral cords 23 have an amount of openings 31 corresponding to the amount of support means 21 to be fixed in the lateral cord 23. The distances of the openings 31 along the side strands 23 here correspond to the desired distances of the support means 21 in the longitudinal direction 15 of the bed

10. The positioning of the openings 31 on both opposite side strands 23 is the same so that all

40 support means 21 are arranged opposite each other on opposite longitudinal sides 22 of the spring system 13 and all the sheets 16 run parallel to each other. However, it is also possible to provide the side cords 23 with a greater amount of openings 31 greater than the amount of support means 21 assigned to the respective side cord 23. This allows for the non-displacement fixation of the support means 21 at different points. selected from the side cords 23.

45 In the upper half 28 of the locking element 27, two parallel and elongated jaws 62 are provided. The jaws 62, which run in the longitudinal direction of the blades 16, serve to fix a bumper shock absorber 63 on the lower inner side of the ring 26. For this purpose, the bumper shock absorber 63 made of soft plastic or rubber is held in the support means 21 when inserted between the jaws 62.

50 In the center of the ring 26 of the support means 21 a half-rider 32 is arranged for the intermediate piece 20 at one end of a sheet 16. The half-rider 32 is configured as a semi-arc open from above. The free ends thereof, which delimit the open side of the semi-rider 32, are provided with elongated interlocking projections 33. The interlocking projections 33, molded as a single piece at the ends of the

55 semi-rider 32, run parallel to each other in the longitudinal direction of the sheet 16, to which the support means 21 is assigned.

The complete support means 21, specifically the ring 26, the locking element 27 with both halves 28 and 29, as well as the semi-rider 32 are made of plastic in the form of a single piece. The wall thickness of

E10706547

09-09-2014

ring 26 is sized so that ring 26 can be elastically deformed by applying a load on the respective sheet 16, essentially it can be compressed in a vertical direction. Therefore, the support means 21 allow a vertical upward and downward movement of the ends 19 of the sheets 16. In this case, the half-bearings 32 move up and down in a vertical path. Downward movement

5 maximum of the respective sheets 16 and, consequently, the maximum compression of the support means 21 are delimited by the buffer bumper 63.

The intermediate piece 20 is configured so that it can be mounted by sliding on one end 19 of the respective sheet 16. With the aid of interlocking means not shown in the figures, the intermediate piece 20 is fixed at the end 19 of the respective sheet 16. The intermediate piece 20 has on the lower side two interlocking protrusions 34 which run in the longitudinal direction of the respective lamina 16. The elongated interlocking protrusions 34, which run in parallel with each other, correspond to the interlocking protrusions 33 in the semi-rider 32 of the support means 21 in such a way that the grooves 35 can be inserted above the locking rims 34 of the half-rider 32 in the locking rims 33 of the intermediate piece 20. In this way a joint is produced by drag between the intermediate piece 20 and the support means 21, if the intermediate part 20 is inserted in the half-bearing 32 of the support means 21 by means of n movement in longitudinal direction of the sheet 16. The union of the intermediate part 20 in the semi-rider 32 is secured by means of form-closing ratchets, not shown, which ensure the union between the semi-rider 32 and the intermediate part 20 when being the intermediate part 20 is completely inserted in the semi-rider 23. However, this

20 safety system is configured so that the union of the intermediate part 20 with the half-rider 32 of the support means 21 can be separated.

The intermediate piece 20 is configured so that it corresponds to the cross-section of the respective sheet 16 and can be mounted by sliding perfectly on the end 19 of the sheet 16. For each cross-section 25 of a sheet 16 corresponding intermediate parts 20 are provided. The intermediate pieces 20, adapted to different cross sections of the sheets 16, respectively have interlocking projections 34 and elongated grooves 35 located above that have the same dimensions and distances, whereby different intermediate parts 20 can be joined to semi-bearings 32 of equal support means 21. Thus, for example, sheets 16 of different cross sections can be attached to equal support means 21

30 by using corresponding intermediate parts 20. It is also possible to configure the intermediate parts with a different height. This allows the height of the sheets 16 to vary individually with respect to the support means 21.

The flexible spring system 13, described above, is stabilized by the supporting frame 12. In the example of

35 shown, the supporting frame 12 has two parallel longitudinal profiles 36 and two parallel cross profiles 37. The longitudinal profiles 36 and the cross profiles 37 have a cross section in L with a vertical side 38 and a horizontal side 39 in the lower end of the vertical side 38. The horizontal sides 39 of the longitudinal profiles 36 and the transverse profiles 37 are located in a common horizontal plane of the supporting frame 12. On the horizontal sides 39 of the longitudinal profiles 36

40 rest the flexible side cords 23 of the spring system 13. Therefore, the horizontal sides 39 of the supporting frame 12 serve as support and support for the side cords 23 of the spring system 13 and keep them in the horizontal plane of the supporting frame 12 The front crossbars 25 of the spring system 13 rest on the horizontal sides 39 of the cross sections 37. It is preferably provided, for example, to screw the crossbars 25 on opposite front sides of the spring system 13 to the profiles

45 cross-sections 37 of the supporting frame 12. In this way, the spring system 13 is preferably tensioned in the longitudinal direction 15 in the supporting frame 12, whereby the spring system 13 cannot be moved on the horizontal sides 39 of the longitudinal profiles 36 due to flexible side cords 23. By means of the elastic configuration, similar to a rubber band, of the side cords 23, the spring system 13 can be extended in longitudinal direction 15 to adapt to the length of the respective

50 supporting frame 12.

The spring system 13, supported by the supporting frame 12 and fixed here, is positioned as a unit on the bed frame 11 or inserted into the bed frame 11, so that the bed frame 11 surrounds the support frame 12 and to the spring system 13 supported and supported by it.

55 An alternative embodiment, not shown, of the bed 10 is possible, in which instead of the supporting frame 12 only two longitudinal profiles 36 connected to the front sides of the table-shaped cross members 25 are used, which run in transverse thereto, at opposite ends of the spring system 13. The longitudinal profiles and the crossbars 25 attached thereto form a stable frame, in which the horizontal sides 39 of

E10706547

09-09-2014

the longitudinal profiles 36 support the flexible lateral cords 23.

Another configuration is possible, in which the bed frame 11 is used as the basis for the flexible spring system 13, that is, the supporting frame 12 and the longitudinal profiles 36 disappear. The lateral cords

5 flexible 23 are then placed on parts of the bed frame 11, in particular at an upper edge thereof. The cross members 25 at the ends of the spring system 13 are attached to the bed frame 11 to keep the spring system 13 stretched. In this exemplary embodiment, the bed frame 11 serves as a support for the flexible side cords 23 and for securely fix the spring system 13 by joining the crossbars 25 of the spring system 13 with the bed frame 11.

10 Figure 5 shows another embodiment of the spring system 13 that differs from the spring system 13 shown in Figures 1 and 4 only by a partially different configuration of the support means 40. The parts of the support means 40, which correspond to the support means 21, are provided with the same reference numbers. In this regard, reference is made to the previous description of the support means 21 shown in the

15 figures 1 to 4.

The spring system 13 may have only the support means 40. However, it is also possible that the spring system 13 has both support means 21 and support means 40.

20 The support means 40 differs from the support means 21 by the fact that a smaller oval ring 41 is arranged on the oval ring 26. The longitudinal central axes of both rings 26 and 41, which run parallel to the longitudinal direction of the sheets 16 assigned to the support means 40, are located one above the other. Accordingly, the minor ring 41 is concentrically inserted into the major ring 26. The minor ring 41 is detachably attached to the major ring 26, specifically the locking element 27 of the

25 same. For this purpose, on the lower side of the ring 41 a plate-shaped foot is arranged which is clamped in the locking element 27 between two elongated jaws 43 in the form of L. When the foot 42 of the ring 41 is inserted between the jaws 43 in the longitudinal direction of the sheet 16, the ring 41 is attached to the ring 26 of the support means 40. This separable joint can be secured with the aid of interlocking means also separable (not shown).

30 The minor ring 41 in the major ring 26 of the support means 40 influences the elastic characteristic thereof. The support means 40 initially has a soft elastic characteristic, namely, until the upper part of the smaller ring 26 rests on the upper side on the smaller inner ring 41. For the subsequent compression of the support means 40, both rings 26 and 41 they must be compressed together, so that the support medium

35 40 becomes harder as compression continues to increase. The elastic characteristic can be influenced by the order of magnitude of the outer ring 26 and the inner ring 41, as well as the wall thickness of the inner ring 41 which has a flat and rectangular cross-section. In the example of embodiment shown, the wall thickness of the inner ring 41 is greater than that of the outer ring 26. Therefore, the inner ring 41 is harder than the outer ring 26. The result of this is that when the ring rests outer 26 over inner ring 41 increases

40 clearly the stiffness of the support means 40.

Figure 6 shows another embodiment of the invention that differs from the embodiments described above by a support means 44 with another configuration. In principle, the support means 44 is configured as the support means 41. For this reason the same reference numbers are used again for

45 equal parts.

The support means 44 has a smaller oval stop piece 45 inside the ring 26. The longitudinal central axis of the abutment piece 45 is located on the longitudinal central axis of the ring 26. The abutment piece 45 has two recesses 46, 47 located one above the other. The recesses 46, 47 have the same configuration

50 and specifically have in the shown embodiment shown an almost oval cross section with an elongated horizontal axis.

The stop piece 45 has on the lower side a foot 48 which is configured in correspondence with two parallel jaws 49 in the locking element 27 of the support means 44 and which can be moved in the direction

55 of the sheet 16 between the jaws 49. The connection of the stop piece 45 with the ring 26 of the support means 44 is configured in principle exactly as in the support means 40.

In each recess 46, 47 a filling piece 50, 51 can be inserted, specifically in the longitudinal direction of the sheet 16. The filling pieces 50, 51 allow varying the hardness of the stop piece 45 formed from a

E10706547

09-09-2014

flexible material If filling pieces 50, 51 are not inserted in the recesses 46, 47, the stop piece 45 is relatively soft. By means of a filling piece 50 or 51 in the corresponding recess 46, 47, the hardness of the stop piece 45 can be increased. A greater hardness of the stop piece 45 is achieved, if both recesses 46, 47 are inserted pieces padding 50, 51. Consequently, the flexibility of the support means 44

5 can be adapted correspondingly to the needs. It is also possible to rotate the filling pieces 50, 51 in the recesses 46 and 47, which increases the height of the stop piece 45 until it is in contact with the upper side of the ring 26 without load. In this case, the ring 26 is supported during the initial compression by the stop piece 45, so that the hardness of the support means 40 increases from the beginning.

10 Figure 8 shows an embodiment of the invention that is again differentiated from the previous embodiments by a support means 52 with another configuration. In principle, this support means 52 corresponds to the support means 21 and 44, so that the same reference numbers are used again for equal parts.

15 In the case of the support means 52, a flexible stop part 53 is provided in the outer ring 26. The stop part 53 has an essentially cylindrical ring in the unloaded state with a lower foot 54 corresponding to two parallel jaws 55 in the closure 30 of the ring 26, so that the stopper piece 53 can be fixed with the foot 54 by dragging between the jaws 55 by insertion in the outer ring 26. This creates a detachable joint of the piece of stop 53 with the locking element 27 of the outer ring 26 of the support means 52.

20 The stopper piece 53 has only a single recess 56 with two curvatures 57 placed one above the other and two curvatures 57 located side by side. In the recess 56 a filling piece 58 with an essentially oval cross section can be inserted. According to the representation of FIG. 8, the filler piece 58 can be inserted vertically or transversely into the recess 56. In the case of the filler piece 58 inserted vertically in

25 the recess 56, it is arranged in the curvatures 57 placed one above the other. On the contrary, the filling piece 58 is arranged with the ends in the curvatures 57 located next to each other in the relative position, in which it is inserted flat in the recess 56. The flexible stop part 53 achieves a less or more flexibility depending on whether the filler piece is inserted vertically or horizontally into the recess 56 of the stopper piece 53. Accordingly, the outer ring 26 contacts the stopper piece

30 53 immediately or only after an initial compression. Accordingly, the relative arrangement of the filler piece 58 in the recess 56 of the abutment piece 53 makes it possible to vary the elastic characteristic of the support means 52 in order to provide the spring system 13 with harder or softer elastic properties.

Figure 9 shows a support means 59 according to another embodiment of the invention. In principle, this

35 support means 59 also corresponds to support means 21, so that the same reference numbers are used for equal parts.

The support means 59 has an elastically deformable bellows 60 in the outer ring 26. In the exemplary embodiment shown, the bellows 60 is fixedly arranged below the semi-rider 32 in the upper part of the

40 ring 26. However, it is also possible to provide the bellows 60 with one foot in correspondence with the jaws 61 in the locking element 27, so that it can be detachably attached to the support means 59 by insertion between the jaws 61.

The bellows 60 is configured so that it initially allows an elastic deformation of the ring 26, without the

45 bellows 60 is deformed during this operation. The bellows 60 deforms only after a certain compression of the ring 26, which increases the stiffness of the support means 59.

It is preferably provided to fill the bellows 60 with compressed air by means of a compressed air supply device not shown and thus expand the bellows 60, which varies its elastic properties. The bellows 60 can be expanded in such a way that it comes into contact with the blocking element 27 as the ring 26 is not loaded and, therefore, influences from the beginning the elastic characteristic of the support means 59. It is also possible to inflate and periodically deflate the bellows 60, whereby the respective sheet 16 is moved up and down alternately by the bellows 60. The spring system 13 can thus serve to stimulate the person above.

Variants of the invention, not shown in the figures, provide for assigning functional modules to the spring system and / or its supporting means, in particular the supporting frame 12. These may be separated from the supporting frame 12 or other supporting means and the system of spring 13. However, it is also possible to integrate the functional modules in the support means, for example, the support frame 12, and / or in the spring system 13.

E10706547

09-09-2014

In the case of the functional modules, for example, it is at least one joint that runs transversely to the longitudinal direction 16 of the bed 10 and which provides the support frame 12 with a pivotable head and / or feet.

5 It is possible, above all, to configure the functional modules as driven mechanisms to adjust the supporting means, in particular the supporting frame 12. These drives can be, for example, electromotor drives that pivot the headboard and / or the feet of the bed 10. Functional modules can also make other adjustments or movements in the bed 10, in particular in the supporting frame 12. The carrying means are preferably configured so as to allow any expansion with the desired functional modules.

10 Figures 10 to 12 show an embodiment of the invention that differs from the embodiments described above by a special support means 64. Moreover, the rest furniture corresponds to the rest furniture shown in the previous figures . In particular, the support means 64 are attached to flexible side cords 23 at opposite ends of the sheets 16, preferably elastic sheets, likewise

15 than in the embodiments of the invention described above. This can be done, for example, by locking elements 27 not shown in Figures 10 to 12, as in the case of the support means 21.

The support means 64 has a tubular configuration base part with a rectangular cross-section in the embodiment shown. The base part 65 is essentially sized so

20 that is rigid. Front sides of the tubular base part 65, which run transversely to the longitudinal direction of the sheets 16, are open.

A pendulum 66 is arranged in the tubular base part 65. The pendulum 66 has two pendulum bodies 67 in strip form and separated from each other. The flat pendulum bodies 67 are located in a common plane that cuts the longitudinal axis of the respective sheet 16 in transverse and runs in the center through the tubular base part 65, specifically through the center between the open front sides of the base part 65. The two pendulum bodies 67 together form the only pendulum 66 due to their arrangement in a common plane. The two upper ends of both pendulum bodies 67 are connected to the tubular base part 65 of the support means 64 with a hinge respectively. In the exemplary embodiment shown, the hinges are configured

30 as film hinges 68 for joining the pendulum bodies 67 in a single piece to the base part 65. The lower ends of both pendulum bodies 67 are joined by a horizontal bar 69. In the exemplary embodiment shown, the connection is also carried out by hinges, preferably also film hinges 68. It is also possible to join the lower ends of the pendulum bodies 67 to the bar 69 without hinges, that is, not in an articulated manner.

35 Between the pendulum bodies 67 there is provided a flange 70 located in the same common plane, on which the pendulum bodies 67 of the pendulum 66 are arranged. The flange 70 is joined at the lower end in the form of a single piece, a preferably, preferably rigidly, at the center of the bar 69. The length of the flange 70 is sized so that it exits the base part 65 through an opening 71 in the upper horizontal wall

40 of the base part 65 and protrudes upwards therefrom. The upper end of the flange 70 is attached to an intermediate piece 72. The intermediate piece 72 is slidably mounted as an end piece on one end of the sheet 16 and preferably attached thereto by interlocking. The upper end of the flange 70 may be attached in a single piece and rigidly to the lower wall of the intermediate piece 72. It is also possible to attach a free upper end of the flange 70 to the intermediate piece 72 by interlocking or , given the

45 case, in an articulated manner and, consequently, the support means 64 and the intermediate piece 72 are configured in the form of two pieces.

A lower horizontal wall of the rectangular tubular base portion 65 of the support means 64 is also provided with an opening 73. This opening 73 serves to house a locking element, whereby the means

50 support 64 is preferably fixed by interlocking in the respective lateral cord 23. The blocking element, not shown in Figures 1 to 12, may be fixed by interlocking in the opening 73.

The support means 64 shown here allows oscillations, in particular pendular movements, of the sheet 16 in its longitudinal direction as a result of the arrangement of both pendulum bodies 67 in a plane located 55 between the open front sides of the base part 65 Therefore, a person placed on the bed or other furniture of rest moves from one side to another with a pendular movement oriented in transverse. This pendular movement is possible due to a free movement of the flange 70 that extends through the opening 71. For this purpose, the opening 71 is sized so that the flange 70 can move freely therein. If necessary, the opening 71 can also serve to limit the pendular or oscillating movements of the sheet 16.

E10706547

09-09-2014

The opening is then dimensioned so that at least in the longitudinal direction of the sheet 16 it keeps the pendular movements thereof in predefined limits with respect to a fixed base part 65 of the support means 63.

5 Unlike the embodiment shown in Figures 1 to 12, it is also possible to provide the support means 64 with several pendulums 66 connected in parallel. The two pendulum bodies 67 of each pendulum 66 are located in another plane, these planes running parallel to each other at a small distance. If two parallel pendulums 66 are provided, these together form a parallelogram that causes the flange 70, joined to the pendulums 66, not to participate in the deflection of the pendulum bodies 67 and, therefore, the flange 70 always maintains

10 its preferably vertical orientation.

Figure 13 shows an embodiment of the invention that differs from the example of embodiment of Figures 10 to 12 only by the fact that an additional elastic spring means 74 is located between the support means 64 and the intermediate piece 74 In the exemplary embodiment shown, the spring means 74 is configured

15 as an elliptical ring with open front sides on both sides. The open front sides of the ring are located in vertical planes that run transversely to the longitudinal axis of the sheet 16. The shortest axis of the electric spring means 74 is oriented vertically, while the major axis runs horizontally.

The flange 70 of the support means 64 is fixed as a single piece on the lower side of the spring means

20 elliptical 74. However, it is also possible to separate the flange 70 from the spring means 74 and preferably connect it by interlocking with the aid of suitable joining means. The spring means 74 have on the upper side a semi-rider 75 with opposite interlocking protrusions 76. The semi-rider 75 and the interlocking protrusions 76 serve for the detachable clip-on connection of the spring means 74 with the intermediate piece 72 on the respective end of the elastic sheet 16.

The support means of the embodiments of figures 10 to 13 is preferably made of plastic in the form of a single piece. The individual components of the support means 64 are sized so that they are essentially rigid. Only in the area of the film hinges 68 is there a sufficient elasticity to allow a pendulum movement of the pendulum bodies 67. In the exemplary embodiment of Figures 10 to 12, the

30 intermediate piece 72 can also be joined in the form of a single piece with the flange 70 of the support means 64, although a separate configuration is also possible. In the exemplary embodiment of Figure 13, the support means 64 and the elastic spring means 67 can also be joined together in the form of a single piece. The desired elasticity is produced in particular only in the vertical direction by the corresponding dimensioning of the wall thickness of the spring means 74.

Another alternative embodiment of the invention is possible, in which at least one pendulum 66 is assigned to the spring means 74 or the spring means 74 and the support means 64.

The different support means 21, 40, 44, 52, 59 and 64, described above, may be assigned to the system of

40 spring 13 in any combination. It is also possible to form the spring system 13 from equal support means 21, 40, 44, 52, 59 or 64.

The invention is not suitable only for beds 10, but also for other rest furniture, in particular recliner furniture, sleeping furniture, as well as seating furniture.
