The present invention provides a mattress with an integrated adjustment device.
A first embodiment of an electromotive adjustment mattress according to the invention will be explained in more detail below with reference to FIGS. 1 to 17. In the present case, the same components are provided with the same references in the drawing figures, knowing that some individual references are removed on some figures for visibility purposes. Individual components are also removed in some figures for reasons of representation. Missing components can be supplemented mentally where it makes sense.
FIG. 1 illustrates, in a perspective view and in the manner of a phantom representation, an embodiment of an electromotive adjustment mattress 2 equipped with an integrated electromotive adjustment device. The mattress 2 comprises a common casing 4 (pillowcase) composed of a textile material and in which are housed a planar padding element as well as an electromotive adjustment holding device 6 serving to support the padding element.
The electromotive adjustment holding device 6 is explained in more detail below with the aid of FIGS. 3 to 17.
To allow an overall view, the flat cushioning element filling the space between the lower side of the casing 4 and the upper side of the holding device and covering the holding device 6 for the most part on the whole of its surface is not shown in Figure 1. The cushioning element consists of a flexible elastic material, for example a foam material. Corresponding padding elements, for example traditional mattresses, are known to those skilled in the art as regards their structure and the material used and are therefore not explained in more detail.
The holding device 6 comprises, as explained in more detail below, holding parts adjustable with respect to each other by means of an electromotive drive device also explained in more detail below. FIG. 1 illustrates the mattress 2 with the holding device 6 in an end position of the adjustment movement corresponding to a seated position and in which the holding parts of the holding device 6 are pivotally adjusted with respect to the other.
FIG. 2 illustrates the mattress 2 with the holding device 6 in the other end position of the adjustment movement corresponding to an elongated position and in which the holding parts are fixed with each other in a holding plane for the essential horizontal.
FIG. 3 illustrates the holding device 6 taken in isolation, therefore without the casing 4 and the cushioning element, in the extended position.
Figures 4 to 6 show the holding device 6 in different adjustment positions in which the holding parts of the holding device 6 can be adjusted with respect to each other using the electromotive drive device.
In the embodiment shown, the holding device 6 comprises a central holding part 8 fixed on site during adjustment (see FIG. 3) with one end of which an upper body holding part 12 is hingedly connected and so as to be able to pivot about a horizontal pivot axis 10.
The upper body holding part 12 comprises, in the illustrated embodiment, a neck holding part 14 at the end of which a back holding part 18 is connected in an articulated manner and so as to be able to pivot around a horizontal pivot axis 16. The back holding part 18 is connected, at its opposite end to the neck holding part 14, to a pelvis holding part 22 in an articulated manner so as to be able to pivot about a horizontal pivot axis 20, said pelvis retaining part being connected, with its end opposite to the back retaining part 18, to the central retaining part 8 so as to be able to pivot around the axis pivot 10.
A lower body holding part 26 is connected to the opposite end of the basin holding part 22 of the central holding part 8 in an articulated manner and so as to be able to pivot around a horizontal pivot axis 24, the lower body holding part comprising, in this embodiment, a thigh holding part 28 and a calf holding part 30. One end of the thigh holding part 28 is connected to the central holding part 8 of so as to be able to pivot around the pivot axis 24 while its end opposite to the central holding part 8 is connected to the calf holding part 30 in an articulated manner and so as to be able to pivot around a pivot axis horizontal 32.
The pivot axes 10, 16, 20, 24, 32 are parallel to each other, so that the holding device 6 can be adjusted, starting from the end position of the adjustment movement (extended position) represented in FIG. 4, by an adjustment by pivoting of the holding parts, in the other end position of the adjustment movement (seated position) represented in FIG. 6.
Each of the holding parts 8, 14, 18, 22, 28, 30 defines at its side facing the cushioning element, corresponding to the upper side in the position of use of the mattress 2, a holding surface against which or on which the padding element rests. In the extended position, the holding parts 8, 14, 18, 22, 28, 30 form between them a substantially horizontal holding plane, while the holding parts 8, 14, 18, 22, 28, 30 are adjusted by pivoting with respect to each other in the sitting position.
FIG. 5 illustrates an adjustment position in which the lower body holding part 26 is not adjusted relative to the central holding part 8 while the upper body holding part 12 is adjusted.
In addition to the pivot axes 10, 16, 20, 24, 32, the holding device 6 comprises, in this embodiment, two folding and folding axes 34, 36 (see in particular FIG. 7) arranged at a certain distance l 'from each other in the longitudinal direction of the holding device 6 as well as with respect to the pivot axes. In this case, the folding and folding axis 34 is associated with the central holding part ίο 8 and subdivides it into two individual parts 8, 8 ′ which are folded together by means of the axis of folding and folding 34. The folding and folding axis 36 is associated with the basin holding part 22 and subdivides it into two individual parts 22, 22 ′ which are folded together by means of the axis folding and folding 36 (see Figure 7).
It can be seen in Figure 7 that to fold the mattress, the folding and folding axes 34, 36 are arranged so that the holding parts of the holding device 6 are foldable so on each other with the cushioning element arranged against the holding parts defining, in the folded down state of the holding device 6, a U-shaped cross section. In the folded state of the mattress and thus in the folded down state of the holding device 6, the retaining surfaces of the retaining parts 22 '', 18 and 14 on the one hand and the retaining surfaces of the retaining parts 8 ', 28 and 30 on the other hand are oriented towards each other by the other side and are arranged essentially parallel to each other.
According to the present invention, the term "folding and folding axis" means an axis between two holding parts allowing the holding parts to pivot as long as, in the folded state of the mattress 2 and thus in the state to fold down on the other of the holding parts, the holding surfaces, against which the padding is supported, of at least two holding parts, are oriented towards one another. The folding and folding axis thus allows the support device to be folded down to fold the mattress, to reduce its measured extent in the longitudinal direction and thus to make the mattress compact and to facilitate the transport or storage of the mattress. A folding and folding axis can in particular allow pivoting of two holding parts relative to one another by 45 ° or more, these parts being connected to each other via the axis of in perspective holding 6 of folding and folding drive.
When arranging two axes of folding and folding, the mattress can for example be folded once approximately in the middle to approximately reduce its extension in the longitudinal direction. To further reduce the extension of the mattress in its longitudinal direction, it is however also possible to fold, by means of a folding and folding axis, a first end of the mattress in the direction of the center and then to fold against, by means of of a second axis of folding and folding, the other end of the mattress also in the direction of the middle and thus of folding it above the first end.
In the folded-down state of the holding device 6, the mattress 2 is folded and forms a compact transport and storage unit which can therefore be easily transported. Due to the folding mechanism provided according to the present invention, the mattress 2 can in particular be folded so compactly that it can be shipped by the usual postal or courier routes, so as to avoid any expensive and complicated transport by transporter.
As shown in FIGS. 4 to 7, the folding and folding axes 34, 36 are arranged in the direction perpendicular to the holding plane, therefore in the vertical direction, at the end oriented towards the cushioning element. , therefore above at the level of the holding device 6, while the pivot axes 10, 16, 20, 24, 32 are arranged in the direction perpendicular to the holding plane at the end opposite to the padding element , therefore below at the level of the holding device 6.
FIG. 8 illustrates the holding device 6 in a view To adjust the holding parts of the device with respect to each other, an electromotorized device 38 is provided, this being explained in more detail below.
The electromotive drive device 38 comprises an output drive member which is in drive connection on the one hand with at least one electric motor and in active connection on the other hand with four Bowden cables 40 ', 40' ' , 42 ', 42' '(see Figure 11), these cables being connected so in active connection with the associated holding parts that under the pulling effect of the respective Bowden cables, the respective holding parts can be moved or settled in relation to each other.
In the illustrated embodiment, the Bowden cables 40 ', 40' 'are associated with the lower body holding part 26 to adjust it relative to the central holding part 8 while the Bowden cables 42', 42 ' 'are associated with the upper body holding part 12 to adjust it relative to the central holding part 8.
A common individual electric motor 84 is provided for actuating the Bowden cables 42 ', 42' ', 40', 40 '', this motor being disposed in a housing 44 (motor housing, see FIG. 11 and FIG. 15) of the electromotive drive device 38 and being in rotary drive link, via a worm gear transmission, with a threaded spindle 86 arranged in a rotatable manner on which a spindle nut 46 is disposed securely against rotation and movable linearly in the axial direction of the threaded spindle 86, this nut forming the linearly movable output drive member of the electromotive drive device 38 (see FIG. 15B).
FIG. 15A illustrates the housing 44 composed of two injection molded plastic parts made in the form of half-shells 80, 82, in the closed state. The housing 44 is sealed against the entry of fluid or moisture, by means of sealing means, using at least one seal.
FIG. 15B illustrates the housing 44 with the upper half-shell 82 removed (housing cover). A common individual electric motor 84 is housed in the housing 44, this motor being in drive connection with the spindle nut 46. The spindle nut is part of a spindle mechanism whose threaded spindle 86 is fixedly disposed on site in the housing 44 and is in rotary drive connection with the electric motor 84. In the illustrated embodiment, the rotary drive link is established between the electric motor 84 and the threaded spindle via a screw transmission worm whose worm 88 is formed at the drive shaft at the outlet of the electric motor 84 and is engaged with a helical wheel 90 connected in rotation with the threaded spindle 86. A spherical bearing is provided for rotatably accommodate the threaded pin 86 in the housing 44.
The spindle nut 46 is movably disposed in the axial direction on the threaded spindle 86 and is secured against rotation by means of a linear guide formed in the lower half-shell 80 of the housing 44. For the supply of voltage and excitation of the electric motor 84 are provided with voltage supply and control means, the structure of which is generally known to those skilled in the art and is therefore not explained in more detail here nor illustrated. The threaded spindle 86 rotates in the chosen direction of rotation of the output drive shaft, so that the spindle nut 46 can be moved linearly in either direction to operate the cables Bowden 40 ', 40' ', 42', 42 ''.
The spindle nut 46 also appears in FIGS. 16 and 17, this being shown, for visibility purposes, separately without the threaded spindle 86 in FIGS. 16 and 17.
As to the way in which a holding part of a holding device is adjusted via two Bowden cables respectively, attention is drawn to document EP 2 792 277 B1.
The 42 ', 42' 'Bowden cables (see Figure 16) have a 48' or 48 '' pull cable and a 50 'or 50' 'sheath (cable sheath) respectively. Correspondingly, the Bowden cables 40 ', 40' 'respectively comprise a traction cable 52' or 52 '' and a sheath 54 'or 54' '(see Figure 16).
The operation of the Bowden cables will be explained in more detail below by way of example using the Bowden cable 42 '. The operation of the 42 '' Bowden cable is corresponding.
The traction cable 48 ′ is extended through an opening 54 made in the housing 44 (see FIG. 15Ά). One end of the traction cable 48 'is fixedly fixed in a tensile strength manner to the spindle nut 46 (see FIG. 17) by means of a barrel-shaped fixing element 56'. The other end of the pulling cable 48 'is fixed to the nape holding part 14 by means of another barrel-shaped fixing element (see FIG. 7).
The sheath 50 ′ of the Bowden cable 42 ′ is fixed on the one hand to the housing 44 (see FIG. 15) and on the other hand to the central holding part 8. FIG. 9 illustrates in particular the way in which the traction cable 48 is guided from the central holding part 8 to the neck holding part 14 via the pelvis holding part 22 and the back holding part 18.
The connection of the Bowden cable 42 '' to the neck support part 14 is carried out in a corresponding manner, the Bowden cables 42 ', 42' 'hooking to the different sides of the neck support part 14 relative to the plane longitudinal center of the holding device 6, in order to introduce the adjustment force in a constant manner into the nape holding part 14, so as to avoid any problem of torsion of the nape holding part 14 during adjustment.
To adjust the nape holding part 14 together with the back holding part 18 and the pelvis holding part 22 relative to the central holding part 8, the electric motor 84 drives the threaded spindle 86 so that the 'Spindle nut 46 in Figure 16 or in Figure 17 is moved to the right (or in Figure 15B to the left). The spindle nut 46 thus pulls, using the barrel-shaped fastening elements, on the traction cables 48 ', 48' ', so that the nape holding part 14 can first pivot, together with the back holding part 18 and the pelvis holding part 22, with respect to the central holding part 8 until reaching the end position of the adjustment movement illustrated in FIG. 6 or in FIG. 1.
The Bowden cables 40 ', 40' 'are correspondingly used to adjust the thigh holding part 28 and thus the lower body holding part 26 relative to the central holding part 8. The sheaths 54', 54 '' are in turn fixed on the one hand to the housing 44 (see FIG. 15) and on the other hand to the central holding part 8. The traction cable 52 ′ comprises at one end a fixing element 60 in barrel-shaped and at its other end a barrel-shaped fastening element 62 (see FIG. 8) fixed to the thigh support portion 28. The sheath 54 of the Bowden cable 40 'is fixed on the one hand to the box 44 (see FIG. 15) and on the other hand to the central holding part 8. The connection of the Bowden cable 40 '' to the thigh holding part 28 is carried out in a corresponding manner.
The restoring of the holding parts of the holding device in the starting position of the adjusting movement takes place due to the gravitational force of its own weight as well as that of the person resting on it, however when the drive is connected.
The individual common electric motor 84 is in active connection in the embodiment shown with the upper body holding part 12 and the lower body holding part 26 so that the adjustment of the upper body holding part 12 and of the lower body holding part 26 can be effected in a time-shifted manner, at least in phases, during the adjustment movement. In the embodiment shown, the time shift is made so that the adjustment of the lower body holding part 26 begins after the adjustment of the upper body holding part 12. The Bowden cables 42 ′, 42 '' or 40 ', 40' 'associated with the upper body holding part 12 on the one hand and the lower body holding part 26 on the other hand are made and arranged in such a way that the 'output drive member first pulls, during adjustment, on the Bowden cables 42', 42 '' associated with the upper body holding part 12 and then only during an additional trajectory of the adjustment movement on the Bowden cables 40 ', 40' 'associated with the lower body holding part 26, so that the adjustment of the lower body holding part 26 begins after the adjustment of the upper body holding part.
The spindle nut 46 moves to the right in Figure 16 or Figure 17, thereby first adjusting, as described above, the neck support portion 14 together with the back support portion 18 then the basin holding part 22 relative to the central holding part 8.
Upon further movement of the spindle nut 46, it then engages with the barrel fasteners 60 ', 60' 'so that the thigh support 28 is then adjusted relative to the central holding part 8, together with the calf holding part 30. In this way, during the adjustment, it is first the upper body holding part 12 which is adjusted, followed by the part lower body support 26.
This allows that according to the present invention, the adjustment of the upper body holding part 12 and the lower body holding part 26 occurs in a time-shifted manner at least in phases during the adjusting movement.
In the embodiment shown, the spindle nut 46 (drive member at the outlet) therefore first performs, with respect to the traction cables 52 ', 52' ', a no-load stroke before the nut of spindle 4 6 starts to pull on the traction cables 52 ', 52' 'and thus adjusts the lower body holding part 26. Through the length of the idle stroke it can be fixed constructively, when adjusting the upper body holding part 12 and the lower body holding part 26, if there is, and to what extent, a time offset.
It is however also possible, according to the present invention, to simultaneously adjust the upper body holding part 12 and the lower body holding part 26.
It is also possible, according to the present invention, to adjustably produce only the upper body holding part 12 while the lower body holding part 26 always remains unadjusted in its position shown in FIG. 4 and the Figure 5. It is also possible to provide, for the separate adjustment of the upper body holding part 12 and the lower body holding part 26, at least two electric motors which can be excited independently of one another. . Depending on the respective requirements, it is also possible to provide more than two electric motors.
To support the cushioning element, the holding parts of the holding device 6 are provided, on their side facing the cushioning element (see FIG. 1), with flexible elastic suspension elements, including a suspension element is provided, by way of example in FIG. 3, with the reference 64.
According to the present invention, at least one retaining part also comprises, in addition to the suspension elements 64 arranged on the side facing the cushioning element, additional suspension elements arranged on the side opposite to the cushioning element, that is to say the lower side in FIG. 3, so that the holding device 6 is provided, along its longitudinal extension, at least partly on both sides, with suspension elements. Among the other suspension elements, only one suspension element is provided, for example, with the reference 66 in FIG. 3.
In the illustrated embodiment, the suspension elements 64 are made in the form of slats and are made of plastic.
As shown in FIG. 3, all the holding parts of the holding device 6 illustrated in the exemplary embodiment are provided on both sides with suspension elements 64, 66. It is however also possible, according to the present invention, that only individual holding parts are provided on both sides with suspension elements 64, 66, while other holding parts are only provided with suspension elements 64 on their side facing the cushioning element. The suspension elements arranged on the two sides of the holding device 6 make it possible to increase on the one hand the comfort of suspension. The mattress 2 can also be placed without an additional lower layer on the floor, ensuring sufficient ventilation of the cushioning element.
It can also be seen in FIG. 14 that the holding parts of the holding device 6 are provided on both sides with suspension elements 64, 66.
The adjustment of the pelvic holding part 22 is carried out on the one hand, as previously described, jointly with the back holding part 18 and the nape holding part 14 and the adjustment of the thigh holding part 28 is performed on the other hand with respect to the central holding part 8, under the driving effect of the electromotorized driving device 38. When the thigh holding part 28 is pivoted relative to the part of central support 8, the calf holding part 30 pivots without drive, due to gravity, about the pivot axis 32, relative to the thigh holding part 28, as shown for example in FIG. 11.
To prevent the calf holding part 30 from moving loosely in a set position with respect to the thigh holding part 28 around the pivot axis 32, means for fixing the calf holding part 30 are provided in the adjusted position relative to the thigh support portion 28. These means comprise, in the embodiment shown, a metal flange 68 in the form of a flat iron (see FIG. 7 and FIG. 11) the ends of which are connected in an articulated manner on the one hand, at the points of articulation 29, 31, to the central holding part 8 at a certain distance from the pivot axis 24 and are connected on the other hand to the calf holding part 30, at a certain distance from the pivot axis 32. A flange corresponding to the flange 68 is also placed on the other longitudinal side of the holding device 6. The function of the flange 68 will be explained in more detail later using the figure 27.
In the illustrated embodiment, an additional padding element 70 (see FIG. 1) is arranged on the side, opposite the padding element, of the holding device, so that the holding device is arranged so sandwiched between the padding elements. The surface of the cushioning elements corresponds in this case to the surface of the holding device 2.
A second exemplary embodiment of a mattress 100 according to the invention will be explained in more detail below using FIGS. 18 to 26.
In the illustrated embodiment, the holding device 102 comprises a first central holding part 104 using the ends of which on the one hand a second holding part 110 forming a holding part of the upper body and of on the other hand a third holding part 112 forming a lower body holding part, are connected around pivot axes 106, 108 parallel to each other.
The connection between the second holding part 110 and the first holding part 104 on the one hand and between the third holding part 112 and the first holding part 104 on the other hand is produced in such a way using folding and folding axes that for folding the mattress 100, the third holding part 112 can be folded down on the first holding part 104 and then, the second holding part 110 can be folded down on the side opposite to the central holding part 104, of the third holding part 112.
In the illustrated embodiment, the connection between the first holding part 104 and the second holding part 110 is formed via a first intermediate holding part 114 connected to the first holding part 104 so as to be able to pivot around the pivot axis 106. The second holding part 110 is connected to the first intermediate holding part 114 via a pivot axis 116 parallel to the pivot axis 106.
In the folded or folded state of the mattress 100 (see FIG. 24F), the second holding part 110 is essentially arranged parallel to the first holding part 104, the length of the first intermediate holding part 114 being selected so that in the folded state, integrating the thickness of the padding structure (padding element) of the mattress 100, the distance between a surface facing the second holding part 110 and the first part retaining 104 essentially corresponds to the thickness of the third retaining part 112 with the padding structure and the surfaces of the third retaining part 112 rest against each surface facing the second retaining part 110 and the first holding part 104.
Correspondingly, the connection between the third holding part 112 and the first holding part 104 is formed via a second intermediate holding part 118 connected on one side to the first holding part 104 so as to be able to pivot around the pivot axis 108. The third holding part 112 is connected with the other end of the second intermediate holding part 118 around a pivot axis
120 parallel to the pivot axis 108, the length of the second intermediate holding part 118 being calculated such that in the case of a third holding part 112 folded over the first holding part 104, including the quilting structure, the third holding part 112 and the first holding part 104 are arranged essentially parallel to one another (see Figure 21 and Figure 25).
While in the first embodiment, folding and folding axes are provided in addition to the pivoting axes, the pivoting axes 116, 120 take, in the second embodiment, simultaneously the function of a folding axis and folding.
For the adjustment of the second holding part 110 relative to the first holding part 104, an electromotorized adjustment device is provided comprising an electromotorized drive device in active connection with the holding parts via an adjustment mechanism. The corresponding structure of corresponding electromotive adjustment devices is generally known to those skilled in the art and is therefore not explained here in more detail. The electromotive adjustment device can for example and is in particular produced in the manner described with reference to the first exemplary embodiment.
The electromotive adjustment device is in this case made so that the second holding part 110 with the padding structure can be folded over the first holding part 104 (see FIG. 21 and FIG. 25). An adjustment member of the electromotive adjustment device loosely adjusts the second holding part 110 or the first intermediate holding part connected to it to this end, to allow the second holding part 110 to be folded down onto the first holding part 104 beyond the end position of the adjustment movement set to the maximum defined by the electromotive adjustment device.
In the illustrated embodiment, the third holding part 112 is foldably connected to the first holding part 104 via the second holding part
intermediate 118 (see the figure 21 and the figure 25), without for as much to be adjustable of way electromotive. Yes that East desired in function of requirements respective, the third
holding part 112 can however also be adjusted electromotorically with respect to the first holding part 104.
FIG. 19 illustrates the holding parts 110, 112, 114 in an unregulated starting position in which the second holding part 110 with the first intermediate holding part 114 defines, jointly with the first holding part 104 and the third part holding 112 with the second intermediate holding part 118, an essentially horizontal holding plane.
FIG. 20 illustrates the holding device 102 in an end position adjusted to the maximum of the adjustment movement in which the second holding part 110 with the first intermediate holding part 114 is adjusted to the maximum by pivoting relative to the first part holding 104.
FIG. 21 schematically illustrates the folding of the retaining portions 102, 112 one on the other or on the first retaining portion 104 in order to fold the mattress 100, knowing that components of the retaining device 102 are removed to simplify the representation.
Figures 22 and 23 illustrate the placement of the holding device 102 in the mattress 100. In the illustrated embodiment, the mattress 100 has a cushioning structure 130 comprising, in the illustrated embodiment, at least two elements of horizontal padding arranged one above the other, of which only one upper padding element is identifiable in FIGS. 22 and 23 and is provided with the reference 132.
The padding structure further includes a bottom padding element on which the holding device 102 is placed, as illustrated in Figure 23. After placing the holding device 102 on the bottom padding element, the element of upper padding 132 may be coated on the holding device 102, so as to interposely accommodate the holding device 102 between the lower padding element and the upper padding element 132. The padding structure 130 with the holding device 102 inserted can then be brought into an envelope of the mattress 100, as illustrated in FIG. 24A.
An exemplary embodiment of a method for preparing the mattress 100 for transport or storage will be explained below using FIGS. 24A to 24F.
Figure 24A illustrates the mattress 100 in its original state. To form a compact transport and storage unit, the mattress 100 is brought into an envelope 134 essentially gas-tight formed in this embodiment by a transparent plastic film.
Figures 24B and 24C illustrate how the envelope is first pulled over the mattress 100.
FIG. 24D illustrates the mattress 100 in a state in which the mattress 100 is entirely housed in the envelope 134.
As shown in FIGS. 24B - 24D, the second holding part 110 was first brought into the adjusted end position at the maximum of the adjustment movement relative to the first holding part 104, using the electromotive adjustment device.
A sub-pressure device is then connected to the casing 134 via a flexible pipe 136 and a sub-pressure is produced in the casing 134, thus starting to compress the quilting structure 30 of the mattress 100.
Figure 24F illustrates the mattress 100 in a state in which the padding structure 134 is compressed to the maximum. In this state, the third holding part 112 is folded over the first holding part 104 then the second holding part 110 is folded over the third holding part 112, as shown in FIG. 24F.
Figure 25 illustrates the transport and storage unit 136 formed at the end of the process. It can be seen that the third holding part 112 is folded over the first holding part 104 and that the second holding part 110 is folded over the third holding part 112, so that the second holding part 110 and the first part holding 104 are arranged essentially parallel to each other and that the surfaces of the third holding part 112
rest against the area doing face respectively of the first part of maintenance 104 or from the second part of maintenance 110. In this state, a opening practiced in
the casing 134 to which the flexible pipe 136 is connected is closed in a gas-tight manner, for example by welding the plastic film.
It can be seen that in this way a compact transport and storage unit is formed in which in particular the longitudinal extension defined by the longitudinal extension of the mattress 100 is essentially reduced.
Due to its compact nature, the transport and storage unit can be shipped as a single package. In the case of withdrawal by user, transport is also simplified due to the compact nature of the transport and storage unit 138 and it can be transported without a car.
To further simplify transport, the transport and storage unit 138 may be provided with rollers.
FIG. 26 illustrates an exemplary embodiment in which the transport and storage unit 138 is housed in a package 140, for example made of cardboard, to protect the envelope from any damage during transport and storage. In the illustrated embodiment, the rolling means comprises laterally to a certain rollers being fixed to two rollers 142, 144 arranged at a distance from each other, these packaging 140. A fixing of the rollers 142, 144 with a dowel or rod type fixing element can respectively be provided for this purpose, this fixing being compressed or pressed into the package 140.
After transport to a user, this transport and storage unit 138 can be removed from the package 140 and the envelope 134 can be removed, causing the padding structure 130 of the mattress 128 to expand again and resume its original state and that the holding parts 110, 112 can be unfolded. In this state, the mattress 100 is then ready for use.
The method according to the invention makes it easy and inexpensive to prepare a mattress by forming a compact transport and storage unit which saves space for storage or transport.
FIGS. 27A to 27E show the different kinematic phases during the adjustment of the thigh support part 28 together with the calf support part 30 as well as the function of the flange 68 explained in more detail below. The calf holding part 30 is connected without drive to the thigh holding part 28 by means of the pivot pin 32, so as to pivot, when the thigh holding part 28 is pivoted in the leg part. calf support 30, under the effect of its weight relative to the thigh support part 28. Without additional measures, the calf support part 30 would be loosely movable in a adjusted position relative to the support part thigh 28 around the pivot axis 32. To avoid this, the flange 68 makes it possible to fix the calf holding part 30 in a set position relative to the thigh holding part 28.
Figure 27A illustrates the calf holding part 30 together with the thigh holding part 28 in an unadjusted starting position.
In the illustrated embodiment, the position of the articulation points 29, 31 is chosen so that when the thigh support part 28 is adjusted with the calf support part 30 from a position of departure not set in a first cinematic phase, the calf holding part 30 is first lifted and is not pivoted gu'ensuite, during a second cinematic phase, together with the thigh holding part 28.
As illustrated in FIG. 27B, the calf holding part 30 is firstly lifted (first cinematic phase) when the upper body holding part 28 is pivoted.
As shown in FIGS. 27C and 27D, the calf holding part 30 is then pivoted relative to the upper body holding part 28 during a second cinematic phase.
As can be seen in FIG. 27E, the kinematics of the adjustment movement are produced in such a way that the calf holding part 30 can be lowered at the end of the pivoting movement. FIG. 27E represents the end position of the adjustment movement corresponding to a maximum adjustment. The calf holding part 30 is thus first lifted at the start of the pivoting movement to avoid excessive loading of the lower side of the mattress 2 by friction on the ground.
