DESCRIPTION

Slatted bed base for a bed

[0001] The present invention relates to a slatted bed base for a bed.

[0002] More specifically, the invention is intended to be used to support a mattress in a bed on which a person can sleep.

[0003] It is known that sheet springs are used to support a mattress, and the slatted base has elastic sheets that cross across the slatted base.

[0004] Traditionally, these sheet bases consist of a horizontal frame, the lengths of which are connected to each other by means of sheets that are attached to sheet supports that are normally made of an elastic material such as rubber or plastic.

[0005] Sometimes, these traditional bed bases consist of several segments that may be articulated with respect to each other. Thanks to this, the header or the end of the feet of the horizontal frame can usually be turned until leaving the horizontal plane and set at a certain angle to the horizontal plane to better support the user's head or legs.

[0006] Often, a sheet holder supports two sheets (double sheet) or even three sheets (triple sheet), so that the sheets can not only be tilted individually, but the elasticity of a double sheet or triple sheet is also it can be established by the movement of two or more sliding pieces that provide more or less support through one (third or fourth) underlying extra sheet with a more rigid elasticity that is arranged between the overlying sheets of the double sheet but at a more level low.

[0007] Also known are sheet springs with individually adjustable sheet supports with which the elasticity of the sheets in question can be influenced. The purpose of this adjustable elasticity of the bed bases is to adapt them better to the human anatomy of the user.

[0008] It is also known that a good sleeping position for the person lying on his side is distinguished by the fact that the spine remains in a straight line when sleeping on the side, in which the upper parts of the legs they are preferably elevated at an angle of approximately 120 ° with respect to the trunk, which favors the relaxation of the spine and prevents the increase of unwanted tensions between the vertebrae and the intervertebral discs. It is also known that a good position for sleeping on the back ensures that natural lordosis of the neck, shoulder and kyphosis of the upper back, lumbar lordosis and sacral kyphosis are preserved.

[0009] This straight position of the spine when lying on its side or the preservation of the natural succession of lordosis and kyphosis when lying on the back are more difficult to achieve if the user is lying in a bed where there is no different areas that provide different support in the right place, in other words, a bed that does not show differences in level. These zones can be divided into five zones: the head segment, the shoulder and upper head segment, the lower back segment or lumbar segment, the pelvis segment and the segment of the legs and feet.

[0010] To obtain a straight position of the spine when lying on its side or a correct succession of lordosis and kyphosis, the slats of the slatted base in the shoulder segment and the upper back, as well as in the back segment of the pelvis, should be placed at a lower level than in the lumbar section, so that the natural anatomical shape of the human body when lying on its side or lying on the back is better supported.

[0011] The known systems, for example DE 94 20 452 U1, to improve the support are not sufficiently corrected for this. In a position lying on the side, the connection line between the shoulders is not vertical, but inclined, so that the spine is no longer straight and the legs are not in the desired parallel position. When lying on the back, natural lordosis and kyphosis are not preserved.

[0012] The purpose of the present invention is to provide a solution to the aforementioned drawbacks and other inconveniences by means of a slatted bed base according to claim 1.

[0013] Preferably, when they support a person at rest, the level difference between the highest laminate support of the lower back (17) and the level determined by the highest laminate support of the shoulder area and the upper part of the back (16) can be up to 8 cm, and the difference in level between the laminate support

highest of the lumbar area (17) and the level determined by the highest laminate support of the pelvis area (18) can be up to 6 cm.

[0014] Preferably, the sheets are held in sheet holders that are fixed in a fixed position in an external frame or in an internal frame that is surrounded or otherwise by an external frame.

An advantage of such sheet supports that are fixed in a fixed position is that they ensure that the desired level difference of at least 4 cm between the highest points of the sheets that support the lower back and the plates that at least support one of Adjacent areas is large enough to provide the desired support.

[0015] Preferably, the outer frame consists of two sides in which holes have been drilled into which sheet supports are introduced in a fixed position, and which are connected by sheets to the corresponding sheet supports of the opposite side.

[0016] An advantage of such fixedly mounted sheet supports is that they maintain the relative position of the sheets at all times and guarantee the desired support.

[0017] Preferably, the sheet supports are made of an elastic material such as rubber or plastic, so that they can be adjusted locally to the anatomical and anthropometric properties of the user.

[0018] Preferably, the internal frame consists of two sides in which perforations have been made in which sheet supports are introduced in a fixed position and which are connected by sheets to the corresponding sheet supports of the other side and by which the internal frame is divided into five segments, the head segment, the shoulder segment and the upper back, the lower back segment or lumbar segment, the pelvis segment and the segment of the legs and feet, whereby each segment of the inner frame can be tilted separately at an adjustable angle to the horizontal plane except the lumbar segment, which forms an integral fixed part of the outer frame of the slatted bed base or is surrounded by it and, therefore, it cannot be tilted relative to the horizontal plane.

[0019] An advantage of the tiltable segments is that they also allow the user support to be fixed in positions other than the sleeping position, whereby the lumbar segment is not tiltable and the lumbar area is always properly supported.

[0020] This arises from the ideal sleeping position in which both femurs are elevated with respect to the trunk at an angle between 90 ° and 120 °. This position can be taken both while lying on one side and lying on the back. This position ensures a reduction of the lordosis of the lower lumbar vertebrae by releasing the iliopsoas muscle group that runs from the inside of the back through the pelvis to the inside of the upper legs. When lying on the back, this position also ensures a reduction in the pressure in the cigapofisaria joints of the lumbar vertebrae.

[0021] This position when lying on the back can be achieved by placing a thick pillow under the knees, for example, but even better using the electrically adjustable segments of the slatted base by which the legs are raised relative to to the trunk and by which the different kyphosis and lordosis are preserved thanks to the specific shape of the leaf spring according to the invention. Preferably, the four mobile segments of the inner frame can be electrically or mechanically positioned so that a user can easily place the bed base in several positions.

[0022] Not all segments of the internal frame are tiltable, but they form an integral fixed part of the external frame, so that their mutual position always remains the same and the internal frame is only suitable for a horizontally laid position.

[0023] Preferably, the highest laminate supports of the lumbar segment are in a fixed position in a higher or less elevated position with respect to the horizontal plane.

[0024] A preference of these two possible positions for the laminae that support the lower back is that the higher plates for the lower back can be set in a more or less elevated position, depending on the age, gender and anthropometric and anatomical characteristics. of the user.

[0025] Another advantage of such a position of the higher sheets is that, in a horizontal situation, the lower back is always high enough with respect to the adjacent areas to follow the natural shape of the body, so that, in a position To sleep on the side, the spine can always form a straight line. When lying on the back, natural lordosis and kyphosis are preserved.

[0026] Preferably, one or more double sheets or triple sheets between the sheet supports are provided with two or more sliding pieces, which provide more or less support with one (third or fourth) extra sheet

underlying with more rigid elasticity that is between the overlying sheets of the double sheet or triple sheet but at a lower level.

[0027] An advantage of these sliding parts is that the local elasticity of the sheets in question can be adjusted to a lower or greater elasticity depending on the weight and the anatomical and anthropometric characteristics of the user.

[0028] Preferably, the length of the internal frame or the external frame can be chosen by using a segment of legs or feet longer or shorter so that the length of the entire bed base can be adjusted to the length of the user.

[0029] In order to better show the features of the invention, a few preferred embodiments of a bed base according to the invention are described below by means of an example, without any limiting nature, in reference to the attached drawings. , in which:

[0030] Figure 1 schematically shows the sleeping position of a person sleeping on a slatted bed base 1 of the known state of the art. The sleeping person 2 is lying on the side on the mattress 3, which is supported by the slatted bed base 1, whereby the connection line 4 between the two shoulders 5, 6 is not perpendicular but inclined with respect to the straight line that runs through the spine. This position results in a deformed spine 7. The same can be seen with the connection line 4 'through the hips.

[0031] Figure 2 schematically shows the sleeping position of a person sleeping in a slatted bed base 8 of the slatted bed base according to the invention. The sleeping person 2 is lying on the side on the mattress 3 that is supported by the slatted bed base 1, whereby the connection line 4 between the two shoulders 5, 6 and the hips 4 'is now perpendicular to the straight line that runs through the spine 7.

[0032] Figure 3 shows a side view of an outer frame 9 of the slatted base 8 according to the invention, where the outer frame is made of a monolithic material such as wood or metal, or is made of plastic and is provided in the upper part 10 of curvatures 11, and is provided inside holes 12 where the sheet supports 13 can be fixed.

[0033] Figure 4 shows an internal frame 14 according to the invention, where the internal frame 14 is divided into five segments, the head segment 15, the shoulder and upper back segment 16, the segment of the lower back or lumbar segment 17, the pelvis segment 18, and the legs and feet segment 19.

The segment of the head 15 can be inclined on its axis of rotation 20, the segment of the shoulders and the upper part of the back 16 can be inclined on its axis of rotation 21, the segment of the pelvis 18 can be inclined on its axis of rotation action 22, and the segment of the legs and feet 19 can be tilted on its axis of rotation 23. The lumbar segment 17 is not tiltable and is part of the outer frame 9.

Not all segments are rotatable and form a fixed part of the external frame 9, so only a horizontal position of the slatted base 8 is possible.

[0034] Figure 5 shows a perspective view of a slatted base 8 according to the invention in a horizontal situation, whereby the slatted base 8 is composed of two external frames 9, 9 'which are provided with sheet supports 13, and which are connected by the sheets 24 which are held on one side by a sheet support 13 of the first side and, on the other hand, by the corresponding sheet support 13 '

of the second side. A sheet support 13 can hold two sheets 24 and, in the case of double sheets with adjustable elasticity, also a third stronger sheet 25.

[0035] Figure 6 shows an internal frame 14 that can be deployed according to the invention in the deployed situation whereby the internal frame 14 is divided into four rotating segments, the head segment 15, the shoulder segment and the upper part of the back 16, the segment of the pelvis 18, and the segment of the legs and feet 19, and whereby the segment of the lower part of the back or lumbar segment 17 is not rotatable and is part of or It is surrounded by the outer frame 9, 9 'of the slatted bed base.

[0036] Figure 7 shows a more detailed perspective view of a sheet support 13 of an elastic material such as rubber or plastic, consisting of two head supports 26, 27 in which two sheets 24 fit at one end, each of which is supported by a double elastic chamber 28, 28 ', where the lower chambers are fixed in two cylinders that are fixed in two holes 12 provided for this purpose on the side 9, 9' of the leaf spring 8 according to the invention.

[0037] Figure 8 shows a double slatted bed base according to the invention, whereby two slatted beds 8, 8 'are placed against each other and each has sheet supports 13 which are connected by sheets 24 which they are held on the one hand by a sheet support 13 of the first side 9 and, on the other hand, by the corresponding sheet support 13 'of the second side 9' of each leaf spring 8, 8 '.

[0038] Figure 9 shows the ideal lying position of a person sleeping 29 in a slatted bed base 8 according to the invention in a horizontal situation, whereby the person sleeping 29 forms an angle between 90 ° and 120 ° between the trunk and the femurs.

[0039] Figure 10 shows the ideal lying position of a person sleeping 29 when lying on his back in a slatted base 8 according to the invention in the folded situation, whereby the person sleeping 29 forms an angle between 90 ° and 120 ° between the trunk and the femurs, and whereby the slatted bed base 30 is a variant whereby the lumbar segment 17, which is not rotatable and is part of or is surrounded by the external frame 9, 9 'of the slatted bed base comprises three pairs of sheet supports 31, 32, 33, of which the intermediate pair of sheet supports 32 has the highest level, and the two surrounding pairs of sheet supports 31, 33 occupy a fixed bottom position. This variant provides a constant optimal lumbar support 34 under the mattress 35 on which the sleeping person 29 is lying. The operation of the slatted base 8 according to the invention is very simple and as follows.

[0040] In the completely horizontal situation, the slatted bed base provides a support for a mattress 3 on which a person 2 can sleep lying on its side, where the lumbar segment 17 of the slatted base supports the lower part of the back in particular due to their higher level, and the adjacent segments, that is, the shoulder and upper back segment 16 and the pelvis segment 18, have a lower level so that the natural forms of the human body of the when lying on the side, they can be adjusted better, and the spine 7 of the user is kept in a straight horizontal position without deforming.

[0041] For a person 2 lying on his back, the slatted base 8 also provides adequate support for a mattress 3 so that the succession of natural lordosis and kyphosis are preserved by an elevated lumbar segment and a shoulder segment and of the upper back and segment of the lower pelvis.

[0042] The slatted base 8 can be adjusted in two ways to the individual dimensions or to the body structure of the user. First, by placing the lumbar segment laminate supports 17 at a lower level for which through holes are provided, so that smaller and younger people experience adapted support. Secondly, by increasing the length of the slatted base 8 thanks to the replacement of the segment of the legs and feet 19 with a segment of the legs and feet with a longer dimension.

[0043] As a result of these adjustment mechanisms, the slatted bed base can be used for virtually anyone, except children under 2 years of age.

[0044] Optionally, the slatted bed base can be equipped with folding segments 15, 16, 18, 19 so that the slatted bed base 8 can be folded to use as a chaise longue in a non-horizontal position. In addition, in the folded position of the slatted bed base, the lumbar segment 17, which does not change position, will continue to provide sufficient support for the lower back to ensure user comfort.

[0045] It is understood that the folding mechanism of the tiltable segments can be actuated mechanically or electrically as an option, and can be fixed in several intermediate positions.

[0046] The slatted bed base allows two slats of slats to be placed against each other, whereby a single mattress can cover the surface of both slats.

[0047] An advantage of this provision is that, in this way, a bed for two people is obtained, each one of which has a support slatted base but both are supported by the same mattress, of

so that a double bed with the same therapeutic support is obtained.

[0048] Preferably, the bed bases are equipped with an internal frame (14) that can be positioned electrically, where the electrical positioning is synchronized between both frames.

10 internal so that the position of the mattress remains the same in both bed bases.

[0049] The present invention is not limited in any way to the forms of realization described as examples and shown in the drawings, but a sheet spring according to the invention can be made in all types of shapes and dimensions as described in the following claims.
