Definitions

  • the present invention relates to a device for articulating a bed base around at least one transverse axis, which comprises at least two mobile parts, this device making it possible to articulate the two parts while avoiding any movement in translation of the one of the parts in relation to the other.
  • bed bases comprising at least two parts which are movable relative to one another about a transverse axis, these movable parts being articulated with respect to a bedframe.
  • the transverse axis is located substantially at the level of the pelvis of the user when he is in the supine position, this in order to allow him to raise one or the other or the two mobile parts, which leads , depending on the degree of inclination, to a more or less pronounced lifting of the lower limbs and a more or less pronounced lifting of the trunk.
  • the degree of lifting corresponds to the applications sought.
  • the user being in a substantially seated position will provide a pronounced lifting of the upstream part corresponding to the headboard and a low degree of inclination of the downstream part supporting the lower limbs.
  • the degrees of inclination may be substantially identical.
  • the upstream part corresponding to the trunk will for example be slightly inclined, or even completely horizontal while the downstream part will be very slightly raised, so that the lower limbs are supported at a height very slightly higher than that of the user's trunk .
  • Such positioning can be particularly recommended for people with circulation problems.
  • the articulation device of a bed base comprises at least two parts which are movable relative to the bed frame which supports it, a first part being arranged at the foot of bed and a second part being arranged at the head of the bed, this device being characterized essentially in that the first part comprises a first and a second articulations respectively downstream and upstream, this second articulation comprising an arm fixed parallel to the plane of this first part and articulated with respect to the bed frame and the second part comprising a first and a second articulations with translation, respectively downstream and upstream of this second part, this first articulation connecting the first and the second parts and this second articulation connecting this second part to the articulation arm of the first part.
  • the arm fixed upstream of the first part is mounted at its free end for rotation relative to a transverse axis located in the immediate vicinity of the head of the bed frame.
  • the first articulation which is arranged downstream of the second part is curvilinear and the second articulation arranged upstream of the second part is mounted, at the foot, in translation relative to the arm of the first part, so that the axis of articulation of the first and second parts is merged with the point of competition of the upper planes of these two parts.
  • the second articulation of the second part comprises a base mounted in translation relative to the arm of the first part, a first rod mounted in rotation relative to this base by one of its ends and mounted for rotation and in translation in a slide secured to the second part by its other end, and a second rod mounted for rotation substantially in the middle of the first rod by one of its ends and mounted for rotation relative to the arm of the first part by the other end.
  • the first articulation disposed downstream of the first part comprises a first rod mounted for rotation relative to the first part by one of its ends and mounted for rotation and in translation in a slide provided in the context of reads from its other end.
  • the slide provided in the bed frame and receiving one of the ends of the first rod can be a telescopic rack.
  • the first part comprises a third simple articulation, substantially arranged in its middle part, this articulation allowing only an angle of opening of the sleeping plane greater than 180 °.
  • the first articulation disposed downstream of the first part and downstream of the third articulation comprises a deformable parallelogram, one of the articulation points of which is guided in a slide with a substantially V- shaped profile, so that the first part remains flat at the start of lifting then folds around the third articulation at the end of lifting.
  • the second part comprises a third articulation delimiting a headrest, this third articulation allowing only a closing angle of the sleeping plane less than 180 °.
  • the third articulation comprises a curvilinear flange connecting the headrest to the second part, a curvilinear slide receiving a base on which is rotatably mounted one of the ends of a first flange , the other end being mounted in rotation and in translation in a slide carried by the headrest, upstream of the curvilinear flange, a second flange being mounted in rotation relative to the first flange at one of its ends and relative at the second part at the other end.
  • FIG. 1 a bed base 10 is shown, arranged in a bed frame 12, mounted on legs 14.
  • the bed base comprises two parts, a first part 16, near the footboard, and a second part 18 near the headboard.
  • first and second parts are articulated around a fictitious transverse axis 20.
  • first and second parts have respectively upper surfaces 22 and 24, corresponding to the sleeping plane.
  • the first part 16 comprises a first articulation 26, arranged downstream and a second articulation 28 arranged upstream of this first part.
  • the first articulation disposed downstream of the first part comprises a first rod 30 mounted for rotation relative to this first part around an axis 32 by one of its ends, and mounted for rotation and in translation in a slide 34 provided in the bed frame around an axis 36 by its other end.
  • the slide 34 cooperates with a rack 38 so as to produce a telescopic rack.
  • This first articulation further comprises a second rod 40 articulated in rotation around a axis 42 with respect to the first rod 30 and around an axis 44 with respect to the bed frame.
  • the second articulation 28 of this first part comprises an arm 46, fixed parallel to the sleeping plane 22 of this first part by one of its ends 48 and articulated around an axis 50 by its other end 52.
  • This axis 50 is disposed in the immediate vicinity of the headboard and cooperates with the bed frame.
  • the assembly of the first part and of the arm 46 which is integral with it can tilt around this axis 50.
  • the second part 18 is articulated relative to the first part.
  • first articulation 54 of the second part is arranged downstream of this second part while the second articulation 56 is arranged upstream of this second part.
  • the first articulation 54 arranged downstream of this second part is curvilinear and comprises a curved slide 58, a bellows 60 masks the connecting arms of the first and second parts which are not of direct interest for the invention.
  • curved slide 58 cooperates with an axis 62, integral with the arm 46 of the first part.
  • the second articulation 56 comprises a base 64, mounted in translation in a slide 66, integral and parallel to the arm 46, this base supporting a first rod 68 articulated on the one hand relative to the base around an axis 70 and, on the other hand with respect to the second part, around an axis 72.
  • a second rod 74 is articulated on the one hand with respect to the first rod around an axis 76 and on the other hand directly relative to the arm around an axis 78.
  • the mounting of the first and second parts of this box spring with respect to each other is such that the axis of articulation of the first part with the second part, referenced 20 is also the line corresponding to the intersection of the planes sleeping 22 and 24.
  • the user can raise the first part by pivoting around the axis 50, so that the sleeping surface 22 is inclined from the top for the downstream part towards the base for the upstream part.
  • the second part corresponding to the user's trunk can also be raised with the inclination desired by the user.
  • the curved slide 58 slides around the axis 62 of the arm 46 and the base 64 moves in translation in the slide 66, the two rods 68 and 74 performing the complementary movements.
  • Maintaining in this position can be done by mechanical locking by friction or by any other means well known in this field of bedding.
  • the assembly can be motorized in a known manner to automatically cause the necessary movements of these first and second parts.
  • the first part 16 comprises a third simple articulation 80, around a transverse axis 82.
  • This third articulation allows movements such that the lying surface 22 can be opened with an angle greater than 180 °, so that the end part 84 forming the footrest tilts down relative to the lying plane 22.
  • the first articulation 26 of the first part, arranged downstream, is replaced by an articulation 86 of the deformable parallelogram type with three axes 88, 90, 92, mounted with simple rotation, the first two with respect to the footrest 84 and the third 92 relative to the bed frame.
  • the fourth axis 94 of this deformable parallelogram is mounted displaceable in translation in a slide 96 having a substantially V- shaped profile, so that the first part remains flat at the start of lifting and then folds around the axis 82 of rotation of the third joint 80 at the end of lifting.
  • This figure shows the mounting of the arm 46 and of the first and second articulations 54, 56 of the second part 18.
  • first and second parts 16 and 18 are always articulated around the transverse axis 20, which is also the straight line of competition for the sleeping plans 22 and 24.
  • this second part also includes a third articulation 100, so as to produce a headrest 102 which is itself movable relative to the sleeping plane 24.
  • a curvilinear flange 104 connecting the headrest 102 to the second part 18, a curvilinear slide 106 receiving a base 108 on which is rotatably mounted one end of a first flange 110, the other end being connected to the headrest around an axis 112, this upstream of the curvilinear flange, while a second flange 114 is rotatably mounted relative to the first flange 110, at one of its ends 116 and mounted rotating relative to the second part 18 about an axis 118.
  • the assembly is such that the headrest is articulated around an axis 122 which is also the point of competition of the sleeping plane with the plane 120 of the headrest 102.
  • This transverse axis 122 is also the center of curvature of the curvilinear flange 104, so that there is no displacement in translation of the transverse edge upstream of the sleeping plane 24 and of the downstream edge of the plane 120 of the headrest 102.
  • the user can therefore give the box spring the profile he wishes, whether it is to raise the upper part of the lower limbs, whether to lower the lower part of the lower limbs, to raise the trunk, to raise the upper part of the trunk in relation to the trunk, or simply obtain a comfortable position by folding the trunk in relation to the lower limbs.
  • transverse axis 20 corresponds substantially to the pelvis
  • transverse pivot axis 82 corresponds to the bend of the knee
  • transverse axis 122 corresponding substantially to the neck of the user.
  • Figure 3 shows the different elements seen in cross section.
  • the bed base is produced, for the simplification of assembly and the quality of the final product obtained, from profiles, in particular aluminum profiles, which facilitates the mounting of the various elements thanks to the ribs produced in a known manner in these profiles.
  • box spring shown is a slatted bed base, since these box springs offer numerous possibilities of adjustment and adaptation according to the type of slats and the type of slat support used.
  • the bed base produced makes it possible to obtain a large number of positions, this by simple movements of the user and corresponding perfectly to the ergonomics of the latter.
  • the assembly allows pivoting avoiding any translation of the different parts between them, which eliminates the problem of pinching between the slats upstream and downstream of the different moving parts.
