Definitions
- Adjustable beds have been known for a long while, in particular, for use in hospitals and nursing homes.
- These types of beds often comprise a mattress supporting structure having pivotable sections which enable adjustment of the mattress. For example, by folding some of the pivotable sections relatively the others, parts of the mattress may be raised or lowered, thereby increasing the comfort for the user.
- the beds often comprise a bed stand which supports the mattress supporting structure from beneath.
- mechanics enabling adjustment of the pivotable sections of the bed are typically mounted to the bed stand.
- a problem with adjustable beds is that there is a risk of squeezing or even crushing hands and fingers between movable parts of the bed when it is adjusted. For example, a hand or a finger may be squeezed between the mattress supporting structure and the bed stand or between the pivotable sections of the mattress supporting structure when the bed is adjusted from a raised to a lowered position. Moreover, there is a risk of injury if the user comes into contact with the mechanics under the bed.
- US 7,484,254 discloses an adjustable bed arrangement which to some extent reduces the risk of squeezing hands and fingers.
- the bed arrangement comprises a support frame and an articulated mattress support.
- the support frame to which the mechanics for adjusting the bed is mounted, supports the mattress support from beneath and has a smaller dimension than the mattress support. Due to the difference in size between the mattress support and the support frame, the risk of squeezing a hand or a finger during adjustment of the arrangement is reduced.
- the arrangement comprises an outer frame which supports the support frame.
- the dimensions of the outer frame relatively the mattress support are such that the distance in a lateral direction from the outside of the mattress support to the inside of the outer frame is larger than the thickness of a finger. In this way the risk of squeezing a finger when inclining the bed to a desired position is reduced.
- an objective of the invention is to provide an arrangement for an adjustable bed having an improved squeeze protection.
- an adjustable bed comprising:
- laterally outside is meant outside in an essentially horizontal direction. Typically, “laterally outside” is to be interpreted in the situation when the bed is in its lowered position, that is, when all support sections are in the horizontal plane.
- squeeze-preventing spaces are meant spaces which are formed in order to prevent squeezing and extend over a two-dimensional area.
- the arrangement reduces the risk of squeezing between the support sections during operation of the bed.
- the risk of squeezing at the downwardly exposed areas along the opposite longitudinal sides of the mattress support is reduced.
- the spacing between adjacent support sections is increased at the squeeze-preventing spaces.
- a further advantage is that the mutual spacing between adjacent support sections is smaller at locations where they are hingedly interconnected as compared to the mutual spacing at the squeeze-preventing spaces.
- the squeeze-preventing spaces do not affect the choice of means for interconnecting the support sections.
- connecting or hinging means of a standard type may be used.
- the squeeze-preventing spaces do not affect the strength of the mattress support at the hinging locations.
- the strength of the means used to hingedly interconnect the support sections is not affected by the squeeze-preventing spaces.
- the squeeze-preventing spaces extend along a distance laterally from said longitudinal sides of the mattress support. Thereby, the risk of squeezing is reduced along a distance laterally from the longitudinal sides. In this way, the squeeze protection is further improved.
- the squeeze-preventing spaces present an essentially constant width in the direction of the longitudinal sides. In this way, an object having a dimension smaller than the essentially constant width is protected from squeezing along the squeeze-preventing spaces.
- all or at least some of the squeeze-preventing spaces extend from the longitudinal sides at least to the support stand.
- extension from the longitudinal sides at least to the support stand is to be interpreted when the adjustable bed is in its lowered position, that is, when the interconnected support sections are in a substantially horizontal plane.
- An advantage with this embodiment is that the squeeze protection is further improved. More specifically, as the support stand by itself provides a protection for squeezing between support sections laterally inside of the support stand, at least when the bed is in its lowered or close to its lowered position, the risk of squeezing is highest at the downwardly exposed areas laterally outside of the support stand. Thus, by letting the squeeze-preventing spaces extend all the way from the longitudinal sides at least to the support stand, the risk of squeezing may be significantly reduced, in particular at the downwardly exposed areas.
- the dimensions of the squeeze-preventing spaces are large enough to prevent squeezing of a finger.
- the width of the squeeze-preventing spaces may be at least 2.5 cm.
- the length of the squeeze-preventing spaces that is, the distance they extend from the longitudinal sides of the mattress support, may be larger than 10 cm.
- the length of the squeeze-preventing spaces is larger than 12.5 cm.
- the squeeze-preventing spaces are formed by at least one edge profile of at least one of the adjacent interconnected support sections.
- an easy and flexible way of forming the squeeze-preventing spaces is provided.
- the squeeze-preventing spaces are formed by at least one edge profile in each of the adjacent support sections. In this way, an easy, flexible and symmetric way of forming the squeeze-preventing spaces is provided.

- the dimensions of the mattress support 3 essentially match the dimensions of the mattress 2.
- the dimensions of the mattress 2 may be larger than the dimensions of the mattress support 3, such that the mattress 2 extends over the mattress support 3 in a lateral direction.

Abstract
Description
- The present invention generally relates to the field of adjustable beds and, in particular, to an adjustable bed and an arrangement for an adjustable bed having an articulated mattress support formed from a plurality of hingedly interconnected support sections.
- Adjustable beds have been known for a long while, in particular, for use in hospitals and nursing homes. However, in recent times the demand for adjustable beds has increased also in the residential market. These types of beds often comprise a mattress supporting structure having pivotable sections which enable adjustment of the mattress. For example, by folding some of the pivotable sections relatively the others, parts of the mattress may be raised or lowered, thereby increasing the comfort for the user. Further, the beds often comprise a bed stand which supports the mattress supporting structure from beneath. Moreover, mechanics enabling adjustment of the pivotable sections of the bed are typically mounted to the bed stand.
- A problem with adjustable beds is that there is a risk of squeezing or even crushing hands and fingers between movable parts of the bed when it is adjusted. For example, a hand or a finger may be squeezed between the mattress supporting structure and the bed stand or between the pivotable sections of the mattress supporting structure when the bed is adjusted from a raised to a lowered position. Moreover, there is a risk of injury if the user comes into contact with the mechanics under the bed.
-
US 7,484,254 discloses an adjustable bed arrangement which to some extent reduces the risk of squeezing hands and fingers. The bed arrangement comprises a support frame and an articulated mattress support. The support frame, to which the mechanics for adjusting the bed is mounted, supports the mattress support from beneath and has a smaller dimension than the mattress support. Due to the difference in size between the mattress support and the support frame, the risk of squeezing a hand or a finger during adjustment of the arrangement is reduced. Moreover, the arrangement comprises an outer frame which supports the support frame. The dimensions of the outer frame relatively the mattress support are such that the distance in a lateral direction from the outside of the mattress support to the inside of the outer frame is larger than the thickness of a finger. In this way the risk of squeezing a finger when inclining the bed to a desired position is reduced. - However, although
US 7,484,254 provides some measures for reducing the risk of squeezing hands and fingers in an adjustable bed, there is still room for improvement. - In view of the above, an objective of the invention is to provide an arrangement for an adjustable bed having an improved squeeze protection.
- According to a first aspect, there is provided an arrangement for an adjustable bed, comprising:
- a plurality of hingedly interconnected support sections forming an articulated mattress support for supporting a mattress, and
- a support stand for supporting the articulated mattress support,
- wherein the mattress support, laterally outside the support stand, presents downwardly exposed areas along opposite longitudinal sides of the mattress support, and
- wherein squeeze-preventing spaces are formed between adjacent interconnected support sections at said longitudinal sides, wherein said support sections present a larger mutual spacing at said squeeze-preventing spaces and a smaller mutual spacing at locations where they are hingedly interconnected.
- By "laterally outside" is meant outside in an essentially horizontal direction. Typically, "laterally outside" is to be interpreted in the situation when the bed is in its lowered position, that is, when all support sections are in the horizontal plane.
- By "squeeze-preventing spaces" are meant spaces which are formed in order to prevent squeezing and extend over a two-dimensional area.
- With the arrangement according to the invention an improved squeeze protection is obtained due to the squeeze-preventing spaces. More precisely, the arrangement reduces the risk of squeezing between the support sections during operation of the bed. In particular, the risk of squeezing at the downwardly exposed areas along the opposite longitudinal sides of the mattress support is reduced. By introduction of squeeze-preventing spaces between adjacent interconnected support sections at the longitudinal sides, the spacing between adjacent support sections is increased at the squeeze-preventing spaces. Thereby, objects, such as a finger or a hand, may be located between adjacent support sections without being squeezed, or at least with reduced squeezing, when the bed is adjusted.
- A further advantage is that the mutual spacing between adjacent support sections is smaller at locations where they are hingedly interconnected as compared to the mutual spacing at the squeeze-preventing spaces. In this way, the squeeze-preventing spaces do not affect the choice of means for interconnecting the support sections. In particular, connecting or hinging means of a standard type may be used. Further, the squeeze-preventing spaces do not affect the strength of the mattress support at the hinging locations. In particular, the strength of the means used to hingedly interconnect the support sections is not affected by the squeeze-preventing spaces.
- In connection to this, it is to be noted that the scope of the invention also covers the alternative when the larger mutual spacing extends over a part of the means used to hingedly interconnect the support sections.
- According to one embodiment, the squeeze-preventing spaces extend along a distance laterally from said longitudinal sides of the mattress support. Thereby, the risk of squeezing is reduced along a distance laterally from the longitudinal sides. In this way, the squeeze protection is further improved.
- According to one embodiment, the squeeze-preventing spaces present an essentially constant width in the direction of the longitudinal sides. In this way, an object having a dimension smaller than the essentially constant width is protected from squeezing along the squeeze-preventing spaces.
- According to one embodiment, all or at least some of the squeeze-preventing spaces extend from the longitudinal sides at least to the support stand.
- Here the extension from the longitudinal sides at least to the support stand is to be interpreted when the adjustable bed is in its lowered position, that is, when the interconnected support sections are in a substantially horizontal plane.
- An advantage with this embodiment is that the squeeze protection is further improved. More specifically, as the support stand by itself provides a protection for squeezing between support sections laterally inside of the support stand, at least when the bed is in its lowered or close to its lowered position, the risk of squeezing is highest at the downwardly exposed areas laterally outside of the support stand. Thus, by letting the squeeze-preventing spaces extend all the way from the longitudinal sides at least to the support stand, the risk of squeezing may be significantly reduced, in particular at the downwardly exposed areas.
- According to one embodiment, the dimensions of the squeeze-preventing spaces are large enough to prevent squeezing of a finger. For example the width of the squeeze-preventing spaces may be at least 2.5 cm. Further, the length of the squeeze-preventing spaces, that is, the distance they extend from the longitudinal sides of the mattress support, may be larger than 10 cm. Preferably the length of the squeeze-preventing spaces is larger than 12.5 cm.
- An advantage with this embodiment is that the risk of squeezing a finger, which is the part of the body that most often is squeezed in an adjustable bed, may be reduced.
- According to one embodiment, the squeeze-preventing spaces are formed by at least one edge profile of at least one of the adjacent interconnected support sections. Thereby, an easy and flexible way of forming the squeeze-preventing spaces is provided. In particular, it is advantageous from a manufacturing point of view since the edge profile(s) may be formed in the support sections prior to assembling the mattress support.
- According to one embodiment of the invention the squeeze-preventing spaces are formed by at least one edge profile in each of the adjacent support sections. In this way, an easy, flexible and symmetric way of forming the squeeze-preventing spaces is provided.
- According to a second aspect of the invention, there is provided an adjustable bed comprising an arrangement according to the first aspect and a mattress supported by the mattress support.
- The features, advantages and embodiments of the first aspect generally apply to the second aspect.
- Other objectives, features and advantages of the present invention will appear from the following detailed disclosure, from the attached claims as well as from the drawings.
- Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, step, etc]" are to be interpreted openly as referring to at least one instance of said element, device, component, means, step, etc., unless explicitly stated otherwise. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless explicitly stated.
- The above, as well as additional objects, features and advantages of the present invention, will be better understood through the following illustrative and non-limiting detailed description of preferred embodiments of the present invention, with reference to the appended drawings, where the same reference numerals will be used for similar elements, wherein:
-
Fig. 1 is a bottom perspective view of an adjustable bed when in an upwardly adjusted position according to an embodiment of the invention; -
Fig. 2 is a bottom perspective view of the adjustable bed when in a lowered position; -
Fig. 3 is a bottom view of an articulated mattress support. -
Fig. 4 is a bottom view of an articulated mattress support. -
Fig. 1 illustrates anadjustable bed 1 comprising amattress 2 and an arrangement for anadjustable bed 1 according to an embodiment of the invention. The arrangement for theadjustable bed 1 comprises an articulatedmattress support 3 which supports themattress 2, and asupport stand 4 which supports themattress support 3. InFig. 1 , the bed is shown in an upwardly adjusted position, meaning that parts of themattress support 3 are upwardly adjusted to be in a non-horizontal plane. - The
mattress support 3 comprises a plurality ofsupport sections 3a-d which are hingedly interconnected. The number ofsupport sections 3a-d is at least two. For example, and as illustrated in the figure, themattress support 3 may comprise foursupport sections 3a-d; a head-end section 3a, twomid-sections end section 3d. Adjacent interconnected support sections, such assupport sections bed 1 in such a way that thebed 1 may be adjusted to a desired position. In particular, some of thesupport sections 3a-d may be movable with respect to thesupport stand 4 and some of thesupport sections 3a-d may be stationary with respect to thesupport stand 4. Typically, at least the head-end section 3a and the foot-end section 3d are movable with respect to thesupport stand 4, and at least one of themid-sections support section 3b, is stationary with respect to thesupport stand 4. In the illustrated example,only support section 3b is stationary. Further, themattress support 3 is attached to thesupport stand 4 at thestationary support section 3b. - The
support sections 3a-d may be made from a stiff material. For instance, they may be made of wood. - Further, the
support sections 3a-d has a thickness. For example, thesupport sections 3a-d may have a thickness of about 15 mm. Due to this fact, the mutual spacing between adjacent interconnected support sections may vary as thesupport sections 3a-d are pivoted relatively each other. For instance, the mutual spacing between adjacent interconnected support sections may decrease as these are pivoted relatively each other, starting from a non-pivoted position. - In the illustrated example, the dimensions of the
mattress support 3 essentially match the dimensions of themattress 2. However, the dimensions of themattress 2 may be larger than the dimensions of themattress support 3, such that themattress 2 extends over themattress support 3 in a lateral direction. Further, themattress support 3 and themattress 2 may be formed as two separate units which are attached together. More specifically, themattress 2 may be placed on themattress support 3 and attached to the same. Alternatively, themattress support 3 may be integrated with themattress 2. - Further, the
mattress 2 may be formed in two parts; a bottom part which may be attached to or integrated with themattress support 3, and an upper detachable part (not shown). In this way a user may easily change the upper part of themattress 2 by detaching it from the bottom part. - The
support sections 3a-d are hingedly interconnected at a number oflocations 6. In the illustrated example, each pair of adjacent support sections are hingedly interconnected at two locations. The number of such locations may vary, for example depending on the dimensions of thesupport sections 3a-d. However, each pair ofadjacent support sections 3a-d are hingedly interconnected at at least one location. For example thesupport sections 3a-d may be interconnected by hinges known in the art. - Each pair of
adjacent support sections 3a-d presents a mutual spacing, such as themutual spacing 7 betweenadjacent support sections mutual spacing 7 extends from onelongitudinal side 8a of themattress support 3 to the oppositelongitudinal side 8b of themattress support 3. For beds known in the art, there is a risk of squeezing of objects, such as fingers or hands, betweenadjacent support sections 3a-d along themutual spacing 7 as thebed 1 is adjusted. In particular, the risk of squeezing is high at thelongitudinal sides mattress support 3. This is due to the reason that a user of thebed 1 is more likely to reach thesupport sections 3a-d, and thereby the mutual spacings, at thelongitudinal sides spaces 16 are formed between adjacentinterconnected support sections 3a-d. The squeeze-preventingspaces 16 will be described in more detail below with reference toFigs 2 and3 . - The
support stand 4, which supports the articulatedmattress support 3, may comprise stationary as well as movable parts. Specifically, the stationary parts of thesupport stand 4 may comprise aframe 9. Theframe 9 may have an essentially rectangular shape. Further, the stationary parts of thesupport stand 4 may comprise a plurality oflegs 10 which support theframe 9. Thelegs 10 may for instance may be attached to or integrated with theframe 9. In the illustrated example, fourlegs 10 which are attached at the corners of the essentiallyrectangular frame 9 are shown. As an alternative to legs, thesupport stand 4 may comprise runners or a supporting frame serving the purpose of supporting theframe 9. - Further, the movable parts of the
support stand 4 may comprisemovable elements 11 for supporting thesupport sections 3a-d during adjustment of the bed. Themovable elements 11 may comprise one ormore arms 12 extending from thesupport stand 4. For example, thearms 12 may extend from one ormore beams 13 which are attached to opposite sides of theframe 9. One end of the one ormore arms 12 may further be attached to a movable support section, such assupport section support arm 12b is attached to the movable foot-end section 3d. Alternatively one end of the one ormore arms 12 may abut amovable support section arm 12a is abutting the movable head-end section 3a. More precisely, at the ends of thearms 12 there may be supportingwheels 14 which may roll or slide against thesupport section 3a during adjustment of thebed 1. - The support stand 4 may further comprise electrical drive means (not shown) for operating the
movable elements 11 to adjust thebed 1. The electrical drive means may typically be supported by theframe 9 of thesupport stand 4 and be operatively connected to thebeams 13. -
Fig. 2 is a bottom perspective view of theadjustable bed 1 ofFig.1 when in a lowered position, meaning that themattress support 3 is in an essentially horizontal position. - As described with reference to
Fig. 1 , squeeze-preventingspaces 16 are formed between adjacentinterconnected support sections 3a-d in order to reduce the risk of squeezing during adjustment of thebed 1. In the illustrated example, squeeze-preventingspaces adjacent support sections interconnected support sections 3a-d, the risk of squeezing is reduced. The squeeze-preventing spaces are at least formed at thelongitudinal sides 8a-b of themattress support 3. In this way, the risk of squeezing is reduced at thelongitudinal sides 8a-b where the risk of squeezing is particularly high. However, in general, the squeeze-preventing spaces may extend from onelongitudinal side 8a to the otherlongitudinal side 8b, with exception for the locations where thesupport sections 3a-d are interconnected. For instance, the squeeze-preventing spaces may also extend between the hinging locations, such as between hinginglocations - Further, due to the squeeze-preventing
spaces 16, themutual spacing 7 between adjacent support sections is larger at the squeeze-preventing spaces and smaller at thelocations 6 where thesupport sections 3a-d are hingedly interconnected. For example, themutual spacing 7 betweenadjacent support sections spaces locations support sections 3a-d. Further, the smaller mutual spacing at thelocations 6 where thesupport sections 3a-d are hingedly interconnected may vary betweendifferent locations 6. For example, themutual spacing 7 at hinginglocation 6a may be smaller than themutual spacing 7 at hinginglocation 6b. - With this arrangement, the squeeze-preventing
spaces 16 do not affect themutual spacing 7 at thelocations 6 where thesupport sections 3a-d are hingedly interconnected. This implies for instance that the same connecting means may be used to interconnect thesupport sections 3a-d regardless of whether there are squeeze-preventing spaces or not. In other words, the choice of connecting means is not affected by the existence of the squeeze-preventing spaces and, in particular, standard connecting means known in the art may be chosen. Moreover, as themutual spacing 7 is smaller at the hinginglocations 6, the strength of the connecting means is not affected by the squeeze-preventing spaces and hence an improved squeeze-protection may be obtained at the same time as the strength of the connecting means is unaffected. - As further illustrated in
Fig. 2 , themattress support 3 extends laterally outside of thesupport stand 4, here meaning that themattress support 3 extends laterally outside of theframe 9 when thebed 1 is in a lowered position. The part of themattress support 3 which extends laterally outside of thesupport stand 4 presents downwardly exposedareas 15 along oppositelongitudinal sides mattress support 3. As thesupport stand 4 to some extent protects hands from reaching and squeezing betweensupport sections 3a-d laterally inside of thesupport stand 4, the risk of squeezing in the absence of squeeze-preventingspaces 16 is considerably higher at the downwardly exposedareas 15 outside of thesupport stand 4 than inside of thesupport stand 4. - The squeeze-preventing
spaces 16 extend along a distance laterally from thelongitudinal sides mattress support 3. In the embodiment shown inFig. 2 the squeeze-preventingspaces 16 extend from one of thelongitudinal sides support stand 4. In other words, the distance along which the squeeze-preventingspaces 16 extend is at least as long as the lateral distance from thelongitudinal sides 8a-b to the support stand when the bed is in a lowered position. In this way, the mutual spacing between adjacentinterconnected support sections 3a-d is increased at the downwardly exposedareas 15, and hence the risk of squeezing at the downwardly exposedareas 15 is reduced. -
Fig. 3 illustrates an articulatedmattress support 3 which comprises a plurality of hingedlyinterconnected support sections 3a-d, which are interconnected atlocations 6. Further, themattress support 3 comprises squeeze-preventingspaces 16a-f which are formed between adjacentinterconnected support sections 3a-d atlongitudinal sides mattress support 3. The squeeze-preventingspaces 16a-f may be empty or covered by, or filled, with some, preferably soft, material. - The squeeze-preventing
spaces 16a-f extend laterally from thelongitudinal sides spaces 16a-f. For example, the distance Df of the squeeze-preventingspace 16f betweenadjacent support sections space 16d betweensupport sections - Further, the squeeze-preventing spaces present a width in the direction of the
longitudinal sides longitudinal sides spaces 16a-f laterally extend. Alternatively, the width may be variable along the squeeze-preventing space. For example, the width may be larger at thelongitudinal sides longitudinal sides space 16d may be larger than the width Wf of the squeeze-preventingspace 16f. - As described above, the distances and widths of the squeeze-preventing
spaces 16a-f may vary. Preferably, however, the dimensions of the squeeze-preventing spaces are large enough to prevent squeezing of a finger. For instance, the width of the squeeze-preventing spaces may be at least 2.5 cm, which is approximately the size of a finger. - In the illustrated example there are two squeeze-preventing
spaces 16a-f between each pair ofadjacent support sections 3a-d, one at eachlongitudinal side spaces support sections mattress support 3 comprises more or fewer than two squeeze-preventing spaces between each pair ofadjacent support sections 3a-d. For example, there may be no squeeze-preventingspaces 16a-f between some of thesupport sections 3a-d or there may only be squeeze-preventingspace 16a-f between some of theadjacent support sections 3a-d. Further, there may only be squeeze-preventingspaces 16a-f at one of thelongitudinal sides spaces 16a-f at thelongitudinal sides adjacent support sections 3a-d. For instance, there may be additional squeeze-preventing spaces (not shown) laterally inside of thelocations 6 where thesupport sections 3a-d are hingedly interconnected. - The squeeze-preventing
spaces 16a-f may be formed by at least oneedge profile 17 of at least one of the adjacentinterconnected support sections 3a-d. By edge profile is meant a profile which is cut out at an edge of a support section. Here, an edge profile typically extends essentially laterally from one of thelongitudinal sides 8a-b of themattress support 3. InFig. 3 , each squeeze-preventingspace 16a-f is formed by oneedge profile 17 in each of theadjacent support sections 3a-d. In the illustrated example, the squeeze-preventingspace 16b is for example formed by oneedge profile 17 in each of theadjacent support sections - Preferably, the
profiles 17 have rounded smooth edges and corners as sharp edges and corners may cause injury. In particular, it is preferred if theprofiles 17 have rounded corners at thelongitudinal sides 8a-b as illustrated inFig. 3 . -
Fig. 4 shows an alternative embodiment of amattress support 3 in which each squeeze-preventingspace 16a-f is formed by oneedge profile 17 in one of theadjacent support sections 3a-d between which the squeeze-preventing space is formed. For instance, the squeeze-preventingspace 16b is formed by anedge profile 17 insupport section 3b, whereas no edge profile is cut out in theadjacent support section 3a. Alternatively, the squeeze-preventingspace 16b could be formed by anedge profile 17 insupport section 3a and noedge profile 17 insupport section 3b. As shown inFig. 4 no edge profiles at all are cut out in some of the support sections. More precisely, no edge profiles are cut out insupport sections support sections - The embodiments of
Figs 3 and4 may be combined in that some squeeze-preventingspaces 16a-f may be formed by anedge profile 17 in only onesupport section 3a-d, and some squeeze-preventingspaces 16a-f may be formed byedge profiles 17 in both adjacentinterconnected support sections 3a-d. For example, squeeze-preventingspaces edge profile 17 as shown inFig. 4 , and the remaining squeeze-preventingspaces 16c-f may be formed byedge profiles 17 in bothadjacent support sections 3a-d as shown inFig. 3 . - The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
