Definitions
- the present invention relates to a twin bed having adjustable bed bottoms and headboards.
- Adjustable bed bottoms are known in numerous embodiments. At least the upper body section and sometimes all sections are movable upwardly in order to obtain positions of the bed bottom which are adapted to a specific use. Bed bottoms for normal home use are adjustable to obtain a comfortable sit-up position, for example to read in bed or to watch television (see for example US 3,305,877 and US 3,877,088 ). These bed bottoms combine a downward movement of an intermediate section with an upward movement of the upper body section. Especially in twin beds having a common mattress, a common topper mattress or mattress cover, such upward adjustment of the bed bottom is impossible or at least cumbersome.
- a further adjustable bed is described in WO 2006/026152 A3 , FR-A-2 841 754 , from which claim 1 has been delimited, discloses a twin bed having adjustable headboards at the head end of the frame, each headboard being adjustable between a substantially vertical position and a position in which the headboard extends obliquely downwardly from the head end of the bed towards a mattress to be supported by the bed bottom.
- GB-A-440,551 discloses a hospital bed comprising a bed bottom supported in the frame, the bed bottom having a plurality of transverse support sections including at least a foot rest section, an upper body section and at least one intermediate section, adjacent to each other in longitudinal direction of the bed to support a mattress thereon in an adjustable manner, such that the bed bottom is adjustable from a first position wherein all support sections are substantially in line to a second position in which the at least one intermediate section is moved downwardly.
- the present invention aims to provide a twin bed which provides very comfortable sit-up positions for one person without disturbing the other person in the twin bed, while it is possible to use the twin bed with a two persons mattress or a mattress cover covering the two mattresses.
- twin bed according to the invention comprises the features of claim 1.
- one intermediate section and an adjacent support section - which may be the upper body section or a second intermediate section - are pivotable downwardly such that facing ends thereof move downwardly.
- an adjacent support section - which may be the upper body section or a second intermediate section - are pivotable downwardly such that facing ends thereof move downwardly.
- the bed bottom for example to create a lowest point in the bed bottom at different longitudinal positions, to adapt the bed bottom to longer or shorter persons.
- a bridge section is supported on two adjacent pivotable sections, overlapping both sections and being pivotally connected to one of said pivotable sections and being slidably supported by the other pivotable section.
- Such bridge section covers the gap between two pivoting sections and creates a small flat bottom of the recess in the bed bottom.
- An important embodiment is characterised in that longitudinal edges of each bed bottom for supporting the mattress remain stationary during movement of the bed bottom between the first and second positions.
- the edges of the mattress remain stationary when the bed bottom is adjusted and there is only created a recess in the bed bottom and in the mattress were a person is lying or sitting, i.e. in a transversally central portion. This further reduces the disturbance between the bed bottoms.
- each bed bottom comprise pivotable side flaps pivotally connected to the longitudinal edges and resting with their free ends on the support sections, said side flaps preferably extending only in the region of the downwardly movable support sections, the free ends of the side flaps being configured to remain in contact with the pivotable support sections, and preferably have a shape adapted to the shape of the bed bottom in the second position.
- the bed bottom may be adjusted manually and/or by means of the weight of a person, manually by spring force or motorised by means of electric, hydraulic or pneumatic motors.
- each headboard of the bed is provided with a spring element allowing at least in some of the inclined positions of the headboard an at least limited pivoting movement back towards the vertical position.
- the headboard allows some resilience and adaptation to the persons position and for example to the position of the mattress on the bed bottom. This is further improved if each headboard is provided with a cushion supported by a flexible support which is allowed to flex also at the lower end, as a headboard may then even better adapt itself to the back of the person resting against the headboard.
- Figs. 1A-F show various principal embodiments of one of the bed bottoms 1 in a twin bed according to the invention.
- the bed bottom 1 has a plurality of transverse support sections including at least a foot rest section 2, an upper body section 3 and one or more intermediate sections 4-6. These sections are positioned adjacent to each other in longitudinal direction of the bed to support a mattress thereon in an adjustable manner.
- the bed bottom 1 is adjustable from a first position in which all support sections 2-6 are substantially in line (not shown) to a second position in which at least one of the intermediate sections 4-6 is moved downwardly from the first position to the second position.
- Fig. 1A there are three intermediate sections 4-6 which can be moved downwardly to form a recess in the bed bottom between the foot rest section 2 and the upper body section 3.
- the central intermediate section 5 forms the bottom of a recess and the other intermediate sections 4, 6 form inclined walls thereof.
- FIG. 1B there is only one intermediate section 4 which is movable up and down in a horizontal manner to form the bottom of a recess between the foot rest section 2 and the upper body section 3 of the bed bottom 1.
- Fig. 1C shows an embodiment in which two intermediate sections 4, 5 and the upper body section 3 are movable to form a recess between the foot rest section 2 and the head end of the bed.
- Fig. 1D has one movable (pivotable) intermediate section and a pivotable upper body section 3.
- Fig. 1E there is an embodiment comprising two pivotable intermediate sections 4, 5 which are connected in such a way to each other that no gap will occur when the intermediate sections 4, 5 are moved to there downward position.
- Fig. 1F shows a variation in which the length of the upper body section 3 and the intermediate sections 4 and 5 have been varied.
- Fig. 1G there are again two pivotable intermediate sections 4, 5, but a gap 7 is created between the ends of the downwardly pivotable intermediate sections 4, 5 that are facing each other. Furthermore, the intermediate section 5 has its pivoting axis positioned between its ends so that the end remote from the other pivoting section 4 will move slightly upwardly when its other end is moved downwardly.
- the foot rest section 2 is movable, although in all embodiments shown in Fig. 1 the foot rest section 2 is stationary. This is preferred to keep the bed bottom simple and concentrate the movement of the bed bottom in the region of a person's bottom.
- the downward movement of the intermediate section is independent and not the result of an upward movement of one of the other sections, as is known from some prior art bed bottoms.
- the length of the various sections of the bed bottom 1 may be varied, and may also be adjustable.
- the bed bottom sections are either stationary or movable (from the aligned horizontal position) in downward direction only. According to the invention it is preferred that the bed bottom sections will be movable mainly downwardly from their horizontal position. If there would be an upward movement from the horizontal position, this would be small.
- Figs. 2A-F show how the embodiment of Fig. 1F can be adjusted, in this case by the weight of a person lying in bed. Versions with mechanical or electrical actuators are also possible.
- the circle P symbolises the bottom of a person. In Fig. 2A the person is lying with its bottom at the position of the intermediate sections 4, 5. When this person P exerts a force (symbolised by a downward arrow) the intermediate sections 4, 5 will pivot downwardly, preferably against the force of a spring and preferably after unlocking a lock which holds the intermediate sections 4, 5 in their upper position in which they are aligned with the foot rest section 2 and the upper body section 3.
- Fig. 2C shows that the intermediate sections 4, 5 can be locked in there downwardly moved positions by a manually actuable lock 8 preventing the intermediate sections 4, 5 from moving upwards again under the force of the springs, also when there is no weight from a person P resting on the intermediate sections 4, 5, as is shown in Fig. 2D .
- Fig. 3 shows a further embodiment of one of the bed bottoms 1 of the twin bed according to the invention in which it is possible to readjust the lowest point of the recess in the bed bottom 1, which can be chosen by the person lying on the bed bottom 1 according to a position suiting that persons body length.
- the intermediate sections 4, 5 and the upper body section 3 are pivotable with respect to each other in a different manner, so that different positions of the three sections can be obtained.
- Fig. 3C shows the position in which the intermediate section 4 has started to move, such that it is now aligned with the intermediate section 5. The lowest point has not been repositioned, but the shape of the recess has changed.
- FIGs. 4A, B show positions of the bed bottom 1 which are comparable to those of Fig. 3E and 3B .
- FIGS. 4A, B show positions of the bed bottom 1 which are comparable to those of Fig. 3E and 3B .
- These figures illustrate the co-operation between the bed bottom 1 and an adjustable headboard 9 which can take up various positions in order to enable a person lying in bed to sit-up in bed in a comfortable position with its bottom, back and head partly in the recess and partly on the headboard 9.
- a particular embodiment of the headboard 9 will be described later on.
- Fig. 5 , 6 and 7 show a practical embodiment of one of the bed bottoms in a twin bed according to the invention.

- the invention provides a twin bed having adjustable bed bottoms and adjustable headboards each enabling a person to sit-up in bed in a comfortable position and even adding to this comfort when used in combination.
- the bed bottom and headboard of the twin bed are very useful, as each person in the twin bed may adjust the bed bottom and/or the headboard without disturbing the other person in the bed, while still providing one large double mattress surface, without a gap, at the same time.
- the adjustable bed bottoms and the adjustable headboards can be therefore be used in a twin bed in combination with a two persons mattress or in a combination with a mattress cover covering the two mattresses.
- the invention is not limited to the embodiments shown in the drawings and described herein before, which may be varied in the different manners within the scope of the claims and their technical equivalents. Aspects of the various embodiments may be combined with each other. For example, it would be possible not to move the one or more bed bottom sections downwardly with respect to the stationary longitudinal edges of the bed bottom but to move the longitudinal edges upwardly while one or more bed sections remain at a lower level thereby creating a level difference between the longitudinal edges and a central portion of one or more bed bottom sections. If the bed bottom is intended to be placed in a specially adapted bed frame, the stationary longitudinal edges of the bed frame could be integrated in the bed frame, while the bed frame may have wedged sides to hold and support the sides or edges of the mattress when the bed bottom is moved.

Abstract
Description
- The present invention relates to a twin bed having adjustable bed bottoms and headboards.
- Adjustable bed bottoms are known in numerous embodiments. At least the upper body section and sometimes all sections are movable upwardly in order to obtain positions of the bed bottom which are adapted to a specific use. Bed bottoms for normal home use are adjustable to obtain a comfortable sit-up position, for example to read in bed or to watch television (see for example
US 3,305,877 andUS 3,877,088 ). These bed bottoms combine a downward movement of an intermediate section with an upward movement of the upper body section. Especially in twin beds having a common mattress, a common topper mattress or mattress cover, such upward adjustment of the bed bottom is impossible or at least cumbersome. Special back rests or adjustable headboards have been designed to allow people to sit-up in bed without adjusting the bed bottom (see forexample GB 2 169 501 EP 1 260 161WO 2006/026152 A3 ,FR-A-2 841 754 claim 1 has been delimited, discloses a twin bed having adjustable headboards at the head end of the frame, each headboard being adjustable between a substantially vertical position and a position in which the headboard extends obliquely downwardly from the head end of the bed towards a mattress to be supported by the bed bottom. -
GB-A-440,551 - The present invention aims to provide a twin bed which provides very comfortable sit-up positions for one person without disturbing the other person in the twin bed, while it is possible to use the twin bed with a two persons mattress or a mattress cover covering the two mattresses.
- For this purpose, the twin bed according to the invention comprises the features of
claim 1. - By moving at least one intermediate section of the bed bottom downwardly, it is possible to create a recess for a person's bottom which creates a much more comfortable sit-up position in bed when the person uses the integrated adjustable headboard as back rest. As it is not necessary to obtain a large downward movement of the intermediate section, it is possible to adjust only one of the bed bottoms in a twin bed, without disturbing the person lying on the other bed bottom having a different position.
- In its most simple form one intermediate section and an adjacent support section - which may be the upper body section or a second intermediate section - are pivotable downwardly such that facing ends thereof move downwardly. Of course, there are many other possibilities to adjust the bed bottom, for example to create a lowest point in the bed bottom at different longitudinal positions, to adapt the bed bottom to longer or shorter persons.
- It is favourable if a bridge section is supported on two adjacent pivotable sections, overlapping both sections and being pivotally connected to one of said pivotable sections and being slidably supported by the other pivotable section.
- Such bridge section covers the gap between two pivoting sections and creates a small flat bottom of the recess in the bed bottom.
- An important embodiment is characterised in that longitudinal edges of each bed bottom for supporting the mattress remain stationary during movement of the bed bottom between the first and second positions.
- Due to this feature, the edges of the mattress remain stationary when the bed bottom is adjusted and there is only created a recess in the bed bottom and in the mattress were a person is lying or sitting, i.e. in a transversally central portion. This further reduces the disturbance between the bed bottoms.
- An even smoother transition between the stationary longitudinal edges of the bed bottom and the recess created therein is obtained if the longitudinal edges of each bed bottom comprise pivotable side flaps pivotally connected to the longitudinal edges and resting with their free ends on the support sections, said side flaps preferably extending only in the region of the downwardly movable support sections, the free ends of the side flaps being configured to remain in contact with the pivotable support sections, and preferably have a shape adapted to the shape of the bed bottom in the second position.
- The bed bottom may be adjusted manually and/or by means of the weight of a person, manually by spring force or motorised by means of electric, hydraulic or pneumatic motors.
- It is especially favourable if each headboard of the bed is provided with a spring element allowing at least in some of the inclined positions of the headboard an at least limited pivoting movement back towards the vertical position.
- Due to this feature, the headboard allows some resilience and adaptation to the persons position and for example to the position of the mattress on the bed bottom. This is further improved if each headboard is provided with a cushion supported by a flexible support which is allowed to flex also at the lower end, as a headboard may then even better adapt itself to the back of the person resting against the headboard.
- The invention will hereafter be elucidated with reference to the drawings showing embodiments of the invention by way of example.

Figs. 12 -14 are views corresponding to those ofFig. 9-11 but with the headboard in an almost horizontal position. -
Figs. 1A-F show various principal embodiments of one of thebed bottoms 1 in a twin bed according to the invention. Thebed bottom 1 has a plurality of transverse support sections including at least afoot rest section 2, anupper body section 3 and one or more intermediate sections 4-6. These sections are positioned adjacent to each other in longitudinal direction of the bed to support a mattress thereon in an adjustable manner. As a result, thebed bottom 1 is adjustable from a first position in which all support sections 2-6 are substantially in line (not shown) to a second position in which at least one of the intermediate sections 4-6 is moved downwardly from the first position to the second position. - In
Fig. 1A there are three intermediate sections 4-6 which can be moved downwardly to form a recess in the bed bottom between thefoot rest section 2 and theupper body section 3. In this recess, the centralintermediate section 5 forms the bottom of a recess and the otherintermediate sections - In the embodiment of
Fig. 1B , there is only oneintermediate section 4 which is movable up and down in a horizontal manner to form the bottom of a recess between thefoot rest section 2 and theupper body section 3 of thebed bottom 1. -
Fig. 1C shows an embodiment in which twointermediate sections upper body section 3 are movable to form a recess between thefoot rest section 2 and the head end of the bed. - The variant of
Fig. 1D has one movable (pivotable) intermediate section and a pivotableupper body section 3. - In
Fig. 1E there is an embodiment comprising two pivotableintermediate sections intermediate sections -
Fig. 1F shows a variation in which the length of theupper body section 3 and theintermediate sections - The variant of
Fig. 1G , there are again two pivotableintermediate sections gap 7 is created between the ends of the downwardly pivotableintermediate sections intermediate section 5 has its pivoting axis positioned between its ends so that the end remote from theother pivoting section 4 will move slightly upwardly when its other end is moved downwardly. - Of course, all kinds of other variations are conceivable, also variations in which the
foot rest section 2 is movable, although in all embodiments shown inFig. 1 thefoot rest section 2 is stationary. This is preferred to keep the bed bottom simple and concentrate the movement of the bed bottom in the region of a person's bottom. The downward movement of the intermediate section is independent and not the result of an upward movement of one of the other sections, as is known from some prior art bed bottoms. The length of the various sections of thebed bottom 1 may be varied, and may also be adjustable. In all embodiments shown, the bed bottom sections are either stationary or movable (from the aligned horizontal position) in downward direction only. According to the invention it is preferred that the bed bottom sections will be movable mainly downwardly from their horizontal position. If there would be an upward movement from the horizontal position, this would be small. One could think for example of a slight upward movement of the section of the bed bottom supporting the knees of a person sitting or lying in bed. -
Figs. 2A-F show how the embodiment ofFig. 1F can be adjusted, in this case by the weight of a person lying in bed. Versions with mechanical or electrical actuators are also possible. The circle P symbolises the bottom of a person. InFig. 2A the person is lying with its bottom at the position of theintermediate sections intermediate sections intermediate sections foot rest section 2 and theupper body section 3. -
Fig. 2C shows that theintermediate sections actuable lock 8 preventing theintermediate sections intermediate sections Fig. 2D . - In
Fig. 2E , thelock 8 is unlocked again, so that the spring force can move theintermediate sections lock 8 to hold theintermediate sections intermediate sections -
Fig. 3 shows a further embodiment of one of thebed bottoms 1 of the twin bed according to the invention in which it is possible to readjust the lowest point of the recess in thebed bottom 1, which can be chosen by the person lying on thebed bottom 1 according to a position suiting that persons body length. In this embodiment, theintermediate sections upper body section 3 are pivotable with respect to each other in a different manner, so that different positions of the three sections can be obtained. - In
Fig. 3A the bed bottom is in its flat position having all sections aligned. - In
Fig. 3B theintermediate section 4 has been maintained stationary and only theintermediate section 5 and theupper body section 3 have been pivoted, so that the lowest point (see arrow) of the recess formed is at the joint between theintermediate section 5 and theupper body section 3. -
Fig. 3C shows the position in which theintermediate section 4 has started to move, such that it is now aligned with theintermediate section 5. The lowest point has not been repositioned, but the shape of the recess has changed. - In
Fig. 3D theintermediate section 4 has been rotated to a larger extent and theintermediate section 5 has followed such that it has taken up a horizontal position, thereby forming the lowest point of the recess over its entire length. - In
Fig. 3E , theintermediate section 5 has been pivoted such that it has become aligned with theupper body section 3 and as a result the lowest point of the recess has been readjusted to the joint between theintermediate sections -
Figs. 4A, B show positions of thebed bottom 1 which are comparable to those ofFig. 3E and 3B . These figures illustrate the co-operation between thebed bottom 1 and anadjustable headboard 9 which can take up various positions in order to enable a person lying in bed to sit-up in bed in a comfortable position with its bottom, back and head partly in the recess and partly on theheadboard 9. A particular embodiment of theheadboard 9 will be described later on. -
Fig. 5 ,6 and7 show a practical embodiment of one of the bed bottoms in a twin bed according to the invention. One can recognise abed tray 1A for a mattress having thebed bottom 1 integrated therein. Thisbed bottom 1 includes a stationaryfoot rest section 2,intermediate sections upper body section 3. Thebed tray 1A will support the edges of a mattress to be supported on thebed bottom 1. Theintermediate section 4 and theupper body section 3 are both pivotable about a horizontal transverse axis, and theintermediate section 4 is driven by a motor, for example through adrive shaft 11 positioned coaxial with the pivot axis. This motor (not-shown) is actuated by the person lying in bed by means of a (remote) control connected to the motor. - The
intermediate sections Fig. 7 ), in this case comprising apin 12 fixed to the end of theintermediate section 4 engaging a longitudinalelongated slot 13 in theintermediate section 5. Through this pin slot connection, bothsections sections sections - In order to create a flat bottom in the recess caused by the downwardly pivoted
sections bridge section 14 which, in this case, is pivotally connected to theintermediate section 5 and slidably connected to theintermediate section 4, while thebridge section 14 overlaps bothsections sections 4 and5, thebridge section 14 will be aligned as well, whereas thebridge section 14 will remain substantially horizontal when theintermediate section 4 and theintermediate section 5 pivot downwardly. Due to thebridge section 14, a mattress will be supported properly and there will be created a comfortable recess in thebed bottom 1 and a mattress resting thereon. - As shown in
Figs. 5 ,6 , the bed bottom is provided with side flaps 30 pivotally connected to longitudinal edges 1' of thebed bottom 1 ortray 1A (Fig. 7 ). Theflaps 30 extend away from its longitudinal axis of rotation over thebed bottom 1, and its longitudinal extent and position is such that the flaps are especially present in the region of the movablebed bottom sections flaps 30 are shaped to remain in contact with the bed bottom when thesections bed bottom 1 is horizontal (Fig. 5 ), to a downwardly inclined position when the bed bottom is in its lowest position (Fig. 6 ). The flaps ensure that a mattress supported on the longitudinal edges 1' and on thesupport sections bed bottom 1 is properly supported adjacent the stationary edges 1' also when the bed bottom is partly moved downwardly. Only in the central part of the mattress and bed bottom (as seen in transverse direction) the recess will be created. - In the embodiment shown, the bed bottom is provided with rigid transverse planks for supporting a spring box mattress, but of course all kinds of support for the
bed bottom 1 are conceivable, depending on the mattress for which it is designed. Therefore, the bed bottom may also have a flexible or spring support. -
Figs. 8-14 show an embodiment of an adjustable headboard already indicated inFig. 4 . The headboard structure orunit 15 is integrated in thebed frame 10 or is a separate structure connected or positioned adjacent to thebed frame 10. - In the very schematic drawings of
Fig. 8 , it is shown that theheadboard 9 can be positioned at various different inclinations, varying from a substantially vertical position (Fig. 8A ) to a substantially horizontal position as is shown inFig. 8C . In order to prevent the lower end of theheadboard 9 from becoming spaced from the upper surface of a mattress M lying on the bed bottom, the movement of theheadboard 9 is caused by a combination of a rotational movement of theheadboard 9 around an upper horizontalrotary axis 16 and a vertical movement thereof. As a result, the lower end of theheadboard 9 will remain at a position close to the mattress M in every different position. Furthermore, theheadboard 9 will be able to be urged against a spring force in downward direction so as to adapt the position of theheadboard 9 more to the circumstances, for example upon downward movements of the upper surface of the mattress M when a person is lying or sitting on it. - The structure of a specific embodiment of one of the headboards in a twin bed according to the invention will be discussed with reference to
Figs. 9-14 showing the headboard in two different positions. - The drawings show that the
headboard unit 15 comprises anadjustable headboard 9 and a frame structure including avertical frame part 17 and aninclined frame part 18, both adapted to be attached to thebed frame 10. - The
headboard 9 comprises aflexible support plate 19 and acushion 20 together forming a comfortable support for the upper body of a person sitting-up in bed. Theflexible support plate 19 is attached to two arms which may be formed by the legs of a U-shaped part, the web of which forms the horizontalrotary axis 16 of theheadboard 9. The rotary axis orshaft 16 is supported by amovable subframe 22 guided with respect to thevertical frame part 17 throughcylindrical guide shafts 23 and movable in vertical direction by means of a motor drivenvertical shaft 24 adapted to move thesubframe 22 and thehorizontal axis 16 supported thereon up and down. Non-electrical versions are also possible, for instance by means of a weight balance and lock, locking the head board at desired positions. - The
vertical frame part 17 and thearms 21 are interconnected by a connectingarm 25 pivotally connected to thevertical frame part 17 and at least pivotally, but in this case also slidably connected to thecorresponding arm 21 at a distance from therotary axis 16. - The connecting
arms 25 are pivotally connected to slides which are slidable in thecorresponding arm 21 to a limited extent, determined by anelongated slot 27 in eacharm 21. Eachslide 26 is biased in the direction of therotary axis 16 by means of a spring, in this case ahelical spring 28 urging the connectingarm 25 to its most upward position, i.e. towards therotary axis 16. - When comparing the positions of the connecting
arms 25 with respect to thearms 21 in the position according toFig. 13, 14 and according toFig. 10, 11 , it will become clear that in the position according toFig. 10, 11 the connection between the connectingarms 25 and thearms 21 is rigid when someone is resting against theheadboard 9, as the connectingarm 25 is urged by thehelical spring 28 to its upward position. When a force is exerted on theheadboard 9, the angle between the connectingarms 25 and thearms 21 is such that the connecting arms will be urged upwardly against their respective stops. However, when the connecting arms are moved to a less inclined position (and thearms 21 to a less inclined position as well) the angle between the connectingarms 25 and thearms 21 will transfer from a acute angle through 90° to an obtuse angle as is shown inFigs. 13 and 14 . When in this position a force is exerted on theheadboard 9, the connectingarms 25 will be urged downwardly away from therotary axis 16 against the force of thehelical springs 28, so that theheadboard 9 becomes springy or resilient enabling theheadboard 9 to yield to a limited extent when a person is resting against theheadboard 9, so that theheadboard 9 is allowed to adapt itself to the person sitting up in the bed. - The control for the motor in the adjustable headboard structure may be combined with the control for the bed bottom and it is also conceivable that some movements are programmed so that the headboard and the bed bottom move in conjunction to one or more positions which are pre-programmed.
- The headboard may have many other shapes or adjusting mechanisms. The headboard may also comprise several sections which are movable with respect to each other either automatically or manually. For example, the headboard may comprise a head supporting section pivotally connected to a back rest section. It is also conceivable to attach the rotary axis to arms pivotable with respect to the frame to move the rotary axis in vertical direction when the headboard is pivoting in order to keep the lower end of the headboard close to the mattress.
- From the foregoing, it will be clear that the invention provides a twin bed having adjustable bed bottoms and adjustable headboards each enabling a person to sit-up in bed in a comfortable position and even adding to this comfort when used in combination. The bed bottom and headboard of the twin bed are very useful, as each person in the twin bed may adjust the bed bottom and/or the headboard without disturbing the other person in the bed, while still providing one large double mattress surface, without a gap, at the same time. The adjustable bed bottoms and the adjustable headboards can be therefore be used in a twin bed in combination with a two persons mattress or in a combination with a mattress cover covering the two mattresses.
- The invention is not limited to the embodiments shown in the drawings and described herein before, which may be varied in the different manners within the scope of the claims and their technical equivalents. Aspects of the various embodiments may be combined with each other. For example, it would be possible not to move the one or more bed bottom sections downwardly with respect to the stationary longitudinal edges of the bed bottom but to move the longitudinal edges upwardly while one or more bed sections remain at a lower level thereby creating a level difference between the longitudinal edges and a central portion of one or more bed bottom sections. If the bed bottom is intended to be placed in a specially adapted bed frame, the stationary longitudinal edges of the bed frame could be integrated in the bed frame, while the bed frame may have wedged sides to hold and support the sides or edges of the mattress when the bed bottom is moved.
