Description

ADJUSTABLE BED

The present invention relates to an adjustable bed, i.e. a bed wherein the back and foot parts may be raised/lowered as desired.

Even though a bed is made for sleeping, many may also want to sit comfortable in the bed. When bedridden due to illness, it is necessary to be able to sit in the bed in order to eat and drink. In a common bed, a backrest may be made from pillows or the like. Pillows tend to provide insufficient support. Thus, there have been designed beds with adjustable bed bases, in which the entire bed base or parts thereof may be elevated and lowered to provide a backrest and/or legrest.

Adjustable beds are in common use in private homes and in the health sector.

Often, such adjustable beds include a frame assembled from three sections or flaps which are hinged together. The angle between the sections is adjusted manually or with motors linked to the sections. A common mattress is laid onto this frame. A drawback with these prior art solutions is that the mattress will be upset along the hinge lines when the ends are raised or lowered. Another drawback is that the mattress easily slips on the frame when the bed is adjusted. Often, the bed is not adapted to the height of the user, and thus the user must change his/her position when the back or foot part is adjusted. It is also a drawback that while the comfort feels optimal when the mattress is lying flat, the mattress is too soft when the bed is raised into a sitting position, i.e. the mattress provides insufficient support. It is felt like a bed adapted for sitting, i.e. that the bed is still felt to be a bed when sitting thereon.

In an effort to improve the ergonomics of such beds, beds are designed with e.g. the head part including a main section located about the back and a head section located about the head. The user of the bed may then raise the head section in case she wishes to lie down, but with the head raised for reading or watching TV, or she may raise the main section to obtain a partly or complete sitting position. Correspondingly, the foot part may be divided into two flap sections, to obtain a buckle in the mattress about the knee of the user when the foot part of the bed is raised. However, this division with flaps will only provide a limited ergonomic effect as long as the bed base is designed from a number of flat flaps. Further, flaps moving in relation to a fixed frame will introduce the danger of being squeezed.

More movable flaps means an increased risk of fingers or other limbs being squeezed between flaps or between a flap and the frame.

It is an object of the present invention to provide a bed wherein raising of at least a part of the bed will maintain an ergonomic lying position and sitting position for the user, while mainly avoiding the drawbacks mentioned above. This is achieved in an adjustable bed as claimed in the appended claims.

The invention will now be described in detail in reference to the appended drawings, in which:

Fig. 14 shows a slat holder which may be used between the bed base and the frame.

Fig. la and lb illustrates the basic idea of the present invention. The figure shows a bed frame 1 with adjustable flaps or profile frames 4, 5 and a bed base with slats placed onto the bed frame 1. In addition to the bed frame 1 with bed base with slats 2 the bed also includes at least a mattress 3 lying on the slats 2, ref. Fig. lb. The slats 2 in the illustrated view are lying on the bed frame 1 as the profile frames 4, 5 are positioned lower than the upper edge of the bed frame when the flaps are not raised.

The adjustment of the bed is achieved using the profiled flaps or profile frames 4, 5. The figures 2 to 5 show different possible positions of the profile frames 4, 5 during raising or lowering of the profile frames 4, 5. As the profile frames 4, 5 are contoured the user will experience an improved ergonomic bed with the flaps raised.

In Fig. 2 the profile frame at the head part or the head flap 5 has been raised so that only the upper part of the frame acts on the mattress 3. The head flap 5 is raised in a movement that also includes the flap being rotated around a point located below the frame. The frame will raise the above-lying slats and shape the bed base. The shape of the mattress is influenced by the flap as it is gradually raised when the head flap 5 is raised. As the outermost edge of the head flap 5 has a quite steep curvature, the flap will act as a headrest in the position shown in Fig. 2, e.g. when it is preferred to lye reading or watching TV.

Fig. 3a and 3b show the bed when the head flap has been raised somewhat more. Then, the flap 5 will support both the head and back of a person sitting/lying in the bed. Fig. 3b is a principle sketch showing how the mattress 3 will be pushed upward by the slats 2, the surface to some degree following the profile of the head flap 5.

Fig. 4 shows the bed when the profile frame at the foot part or the foot flap 4 has been raised. The movement of the foot flap 4 is stepless, as for the head flap 5, which means that the flaps may be set to any desired angle between the lower positions in which the flaps lies relatively flat to an upper position in which the flaps are maximally raised from the frame 1. As with the head flap 5, the foot flap 4 may be raised so that the curvature of the flap is only raising a part of the mattress, in the area below the knees of the user, or it may be raised so that the feet are raised above the base of the bed. The profile shape of the foot flap 4 will provide an ergonomic curvature to the mattress corresponding to a more natural bending of knees and legs compared with what is possible with e.g. two hinged flat flaps.

The head and foot parts may be raised independent of each other. The movements of the head and foot parts may also be connected to each other. When the user wants to adjust the bed into a sitting position, the head part should preferably start to raise itself first. Due to the shape of the profile element, the user will first note that the mattress is rising under the neck. Then, the mattress will also rise in the area around the lumbar. After some rising of the head flap, also the foot part will start rising, while the movement in the head part continues. The curved shape of the profile frames or flaps provides a shape better matching the user's body than prior art solutions based on flat flaps hinged together.

Fig. 5a and 5b show how the bed base and mattress may be shaped when both profiled flaps are in raised positions. The figures only show one configuration of the flaps with a proposed curvature pattern. Obviously, the degree of curvature of the flaps may be adapted to optimize the comfort and user friendliness of the bed without departing from the many benefits of the invention.

Fig. 6 shows in principle how the slats 2 may be supported by resilient elements along the sides. In practice, the resilient elements will be designed as slat holders. The slat holders are described in detail in the following. When the profile frames are raised to the slat holders, they will unload the resilient slat holders and in this way "disconnect" the resilient action.

With the bed in a flat position, the slats 2 will rest on the slat holders/bed frame 1. The slats are springy and may offer the benefit of a thinner mattress without compromising the comfort. When the profile frames 4, 5 are raised lifting the slats 2 from the slat holders/bed frame 1, the bed base becomes harder as there is less distance between the points supporting the slats.

Figure 7 shows a principle sketch of a bed base with resilient slat holders 35 holding pairs of slats 36 over contoured adjustable flaps 4, 5. When a user lies down on a mattress in which the slats are mounted in such a resilient way, the bed base will adapt itself under the loaded points on the user's body 37. A more even distribution of weight is achieved, and a more even load on the body. This may in particular be beneficial for patients that are lying still for prolonged periods and therefore get a constant loading on some parts of the body. This principle will be explained in further detail in reference to an embodiment of a bed according to the invention.

Fig. 8a and 8b show an embodiment of a bed frame according to the invention, without bed base and mattress. The bed frame is mounted on a chassis including two legs 7, 8 and a sub frame with two longitudinal side members 9, 10 tied together by transversal beams 11, 12.

The bed frame is in two parts with a first frame element 13 at the head part and a second frame element 14 at the foot part. The frame elements are U-shaped with an open end, at which the frame elements are joined. The frame elements are closed towards the ends of the bed. The second frame element includes first and second struts 18, 19 connecting the sides.

The first and second frame elements are connected by brackets 15. The second frame element 14 is fixed to the brackets 15, while the first frame element 13 is rotatable mounted to the brackets 15, so the first frame element is allowed to swing a bit upwards, but not allowed to swing downwards below a level position. In the embodiment shown in Fig. 8b this is obtained by means of first penetrating bolts 17 on the first frame element which move in openings in the brackets 15. The range of movement may be limited in other ways, e.g. by the end of the first frame element butting against flanges on the upper and lower side of the brackets.

In addition, the chassis includes two profile frames, the first profile frame 20 and the second profile frame 21, respectively. Both are designed as U-shaped frames. The first profile frame is closed with first and second crossbeams 22, 23, while the second profile frame is open all over. The first profile frame is rotatable connected to the brackets 15 with first and second link arms 24, 25 on each side. The second profile frame is similarly rotatable connected to the other frame element by means of third link arms 26 on each side. The link arms control the motion of the profile frames in such a way that the profile frames are rising with both a rotating and linear movement.

The position of the profile frame is controlled with a motor assembly 27. The motor assembly 27 includes two geared motor drives in a shared elongated housing. The motor assembly is mounted inside the second frame element 14 and bolted to the struts 18 and 19. The motor assembly has two outputs which are frictionally connected to first and second rotating rods 28 and 29, respectively. The rotating rods are suspended in bearings along the sides of the second frame element 14.

On the first rotating rod 28 there are mounted two first lifting arms 30. The lifting arms 30 have castors in the ends. The castors bear against the underside of two shaped elements 32 on the first profile frame 20. The shaped elements 32 are mounted between the end of the profile frame and the first crossbeam 22. When the motor assembly 27 turns the first rotating rod 28 the first lifting arms 30 will be turned upwards and lift the shaped elements 32 and then the profile frame 20. Due to the curvature of the shaped elements the movement will not be even but determined by the curvature and by the length of the lifting arms, i.e. where the arms are bearing against the underside of the shaped elements.

Correspondingly, second lifting arms 33 are mounted onto the second rotating rod 29. The second lifting arms are connected to the second profile frame 21 in the hinged points 34. When the motor is turning the rotating rod 29, the movement will be transferred via the lifting arms to the crossbeam, and lift the profile frame. This is a simplified solution compared with the solution employed at the head part of the bed, but it is certainly possible to employ identical solutions for both profile frames, if required.

In Fig. 9 it is shown an embodiment of a slat arrangement suited for use in an adjustable bed according to the invention. A number of slats 2 are arranged in pairs 36 and joined by a resilient slat holder 35, by which the slats are lying on top of the bed frame. The slats 2 are connected to the bed frame by means of the resilient slat holders. At least some of the slat holders 35 are slideable mounted in tracks or slots on the upper side of the bed frame, not shown. The frame may be made from extruded aluminium profiles, wherein tracks or slots are extruded into the profile.

On the upper side of each slat 2 there is preferably mounted a Velcro® strip. A corresponding layer of Velcro® textile is mounted on the underside of the mattress to be laid on the slats. Thus, when the mattress is laid onto the slats it will stick and be held firmly. Movements arising in the mattress when the bed is adjusted will be absorbed by the slat holders sliding on the bed frame.

As shown on Fig. 9 also the contoured frames or flaps will lie over the bed frame 1, at least partly. The slat holder 35 includes resilient spacers 38 lifting the slats above the bed frame 1 and profile frames 20, 21, which means that the bed obtains a flat surface when the profile frames lie down and the bed is not loaded. Thus, the mattress placed on the slat pairs in the bed base will also lie flat, as on any ordinary bed. When a person is lying on the bed, the mattress will be unevenly loaded and will depress the resilient spacers mainly where the profile frames 20, 21 do not protrude above the frame, as indicated in Fig. 8. When the profile frames are rising from a lower position, initially only some of the slats 2 will be lifted, but as the angle of the profile frames over the bed frame is increased, most slats will be lifted according to the curvature of the profile frames 20, 21. Thus, the ergonomic effect of the curved flaps will be obtained as distinguished from ordinary prior art flat flaps.

As the pairs of slats 36 lie loosely on top of the profile frames and are slideable mounted to the bed frame by the resilient spacers 38, they may shift relative to the frames when the curvature of the mattress is changing when the profile frames 20, 21 are adjusted. In this way the mattress will become far less upset in the folds arising where the slats transit from resting on the bed frame 13, 14 to resting on one of the profile frames 20, 21.

The first frame element 13 is rotatable connected to the second frame element 14. Thus, the first frame element may follow on when the first profile frame 20 is lifted above the bed frame 1. This is particularly advantageous as to the danger of crushing, as there will be no angle between the profile frame and bed frame allowing anything, such as a hand or other subject, to become squeezed. As described above, in the shown embodiment the first frame element 13 is hinged in such a way that it may only be lifted upwards and else lie flat supported by the slat holders 35.

Since the second frame element 14 is fixed, it will be advantageous if only some of the resilient spacers 38 are connected with the frame element. The spacers 38 lying over the second profile frame 21 should lie on top of the second frame element 14 in such a way that they are not connected to the bed frame, and may be lifted when the second profile frame 21 is rising. When these unconnected spacers are lifted from the profile frame 21, the spacers connected with the frame element will slide in tracks in the frame element, the pairs of slats always having a mainly constant distance.

Fig. 10 shows an embodiment of a bed according to the invention in top view. The slats 2 are connected to the slat holders 35 in pairs, the slats 2 lying with an even distance between each slat over the length of the bed. Fig. 11 is a perspective view of the bed in Fig. 10 wherein there is more easily observed how the slats 2 are arranged in pairs 36 and how the slat holders 35 are mounted in a slot 39 in the bed base.

Fig. 12 is a perspective view of an embodiment of a slat holder suited for a bed according to the invention. The slat holder 35 includes a number of resilient spacers 36 interconnected by a connection element 40. The resilient spacers 36 are also equipped with coupling means 41 suited for slideable coupling to the bed frame or one of the frame elements of the bed. The coupling means 41 are small compared with the dimensions of the resilient spacers, meaning that a user of the bed will not observe if the individual coupling means are lying on top of the bed frame or are slideable mounted to it. Further, the resilient spacers are equipped with slat fasteners 42. The slat fasteners 42 may take at least one slat, which will be lying flat in the surface of the bed base of a bed. In the example shown, slats may be mounted in pairs in the slat fasteners. The slats may lie in the slat fasteners without being fixed to these, meaning that a slat may easily be released from the slat holder. This may be useful if a slat has to be replaced, e.g. in case it is broken.

The slat holder 35 may be cast in a polymer material as one element. Optionally, the slat holder may be composed from two different polymer materials, as there are different requirements to the polymer material in the resilient upper part and in the lower sliding part.

When the bed is to be adjusted, here with a flat bed as the starting point, the profiles 20, 21 will be pushed against the underside of the slats 2 and lift them.

This movement occurs gradually, as the lifting starts at the head end. Then, the profile will lift the mattress 2 in the area at the user's lumbar, before the movement propagates to the whole back part. The back and foot parts may be adjusted individually, but the movement may also be connected. The movement will then start in the back part meaning that the head and lumber will be lifted before the foot part starts to move. In the head part of the bed the slat holders 35 will lift the first frame element 13 which is hinged to the brackets 15. At the foot end, where the movement is more limited, the slat holders will be stretched and partly lifted above the frame element 14. The second frame element 14 is fixed, i.e. it is not hinged but fixedly connected to the brackets 15. When the profile elements 20, 21 are raised the mattress will be felt harder, to some means, both due to the slat holders 35 being lifted from the support, and because the profile elements 20, 21 are supporting the slats 2, not at the ends but further in. It is an object to let the system move about an area or imaginary point near the user's hip joint.

In the exemplary embodiment shown in the figures 8-11 the shaped element 32 is used to control the raising movement of the first frame element 20. It is also possible to have solutions in which the lifting arms 30 instead are bearing directly against the underside of the frame element 20. The underside of the frame element may also be curved, e.g. by fastening a shaped element to the underside.

The figures 13 and 14 show a bed according to the invention equipped with mattresses. An outside mattress 43 is mounted around the bed frame enclosing all movable parts. The outer mattress may be fastened to the bed using fastening means (not shown) which e.g. may be fastened to the slat holder, preferably in the resilient spacers of the slat holders. When the profile frames are lifting the slat holders, these fastening means will make the enclosing outer mattress follow the movement of the bed base up and down. Further, the outer mattress 43 is with advantage equipped with a cover stretched below the bed frame, only the legs protruding from the mattress cover, as illustrated in Fig. 15. The outer mattress has also an upper side (not shown) resting on the slats below the mattress topper 44. This may be beneficial when cleaning the bed, mattresses and bedding.

As the mattress and bed frame with legs appear as one integrated element, no movable parts will be accessible in use. The flaps and frames that are raised and lowered during use are enclosed in a mattress arrangement protecting the user, while an even surface on the bed is obtained in all positions. The design of the legs means that the floor below the bed is easily accessible simplifying cleaning. It is also possible to mount a lamp below the bed, which may be activated by the user. This is beneficial if there should be necessary to inspect the area below the bed, which else will be dark, in case of cleaning or for retrieving lost items.

To increase the accessibility of the area below the bed, it is also possible to replace the two legs in the illustrated embodiment with a central leg or to increase the number of legs, if this is desirable.

Please note that it is not significant for the invention if the profile frames are arranged above or below the bed frame, and that both embodiments are possible. Other ways of placing a bed base with slats on top of a bed frame and profile frames may be contemplated, e.g. such as a loose bed base provided with slats explained above to be raised or lowered with the movements of the profile frame.

In both cases an ergonomic shape of the surface of the mattress will be obtained when the contoured flaps are raised.

Using contoured flaps according to the invention entails a number of benefits. By providing the adjustable flaps with at least one curvature, a single flap might work as either headrest or backrest only instead of using several flat flaps moving in relation to each other. It is an advantage of the invention that the number of flaps may be less but also maintaining an ergonomic design of the flaps. Combining a resilient slat holder arrangement with contoured flaps also provide for an improved comfort compared with prior art beds with adjustable flaps.

The interaction of back profile, slat holders, slats and link arms in a bed according to the invention means that the back profiles may shift in the longitudinal direction of the bed, not only as a result of the elevation, but also as a result of the loading. In this way the comfort will be optimal in all positions.

The present invention provides a bed with a particular design wherein the bed is adjusted on the user's premises. The stepless lifting mechanism for adjusting ergonomic shaped supporting profiles and a to-way springy slat system has increased the sitting and lying comfort into another level compared with prior art adjustable beds. The neck rest and lumbar rest are concealed in the bed and may be activated automatically when needed. The construction of the bed provides the system with a unique movement, among other provided by the hinging arrangement which means that the back part of the bed is extended as it is elevated. Due to the contoured profiles the back and seat parts will move according to the natural pattern of the body.

Preferably, the bed is provided with a lamp below, which is practical if light is needed but one wants to avoid wakening others in the room, or if it is necessary to inspect the whole floor below the bed. The lamp may be realized as a LED lamp.

The legs of the bed may be made in any material sufficiently strong to support the bed, such as various metals, e.g. steel, aluminium, titan or alloys of these or other metals. In a preferable embodiment the legs are made in cast aluminium.

The bed may be adjusted using a wireless remote control. The bed may also be adjusted using an App. In this way the light below the bed may be turned on and off, favourite settings may be stored, wakening ordered or the individual beds in a double bed configuration synchronized to take identical positions irrespective of load and setting. The bed and the remote control may communicate e.g. using a closed Bluetooth connection.

The adjustable bed according to the invention has particularly designed slat holders providing a substantially improved comfort compared with prior art slat holders. When a slat holder is depressed, the movement will propagate in the system and lead to the nearest less loaded slat holder being pushed up into the mattress. A double effect is obtained, in which the depression and load is distributed among the slats.

Preferable, the slats are covered with Velcro®, and preferably a strong Velcro® fastening the mattress to the rest of the system of the adjustable bed. Velcro® textiles have varying degree of resiliency, and this resiliency provides that each slat will yield individually. The slat system employed in the illustrated embodiment of an adjustable bed according to the invention may slide freely along the especially designed frame of the bed, and in this way assist in adapting the bed to the user.

The mattress shown on the bed according to the invention has a particular construction providing that the mattress will follow the movements of the user in an optimal way. Whether the user is sitting or lying in a bed according to the invention, the stepless adjustment of the ergonomic shaped support profiles, combined with a two-way yielding slat system will allow the user to receive maximum support where needed by the body. The neck and lumbar support may be activated automatically when needed as the back and seat part of the mattress may be moved according to the natural pattern of the body.

Preferably, an adjustable bed according to the invention should be covered with a textile in a movable stretch material. Then, the textile surface of the bed may follow the movements of the bed avoiding wrinkles and creases on the surface of the mattress.
