Detailed description of embodiments of the invention

The deformable bed base according to FIG. 1 comprises at least one pair of longitudinal blades 10 on which are fixed supports 20 of transverse slats 21 of the bed base. According to this figure, a single transverse slat is shown at the top of the bed base so as not to overload the drawing.

The blades are for example blades made of composite material which can deform by bending.

According to FIG. 1, the blades are fixed to a support frame or chassis 30 in their central part 102 and are deformable between a lower part of the base which is called the foot part 101 and the central part 102 as well as in an upper part. the so-called back and head part

103.

According to a first aspect of the invention shown in particular in Figures 1 and 2, the blades 10 are deformable in the upper part of the base (back and head part 103) by means of a head jack 70 actuating the arms in rotation rotary head 80, the head arms pushing the blades on two levels through rods 81, 82 whose distal ends are articulated in rotation on legs 83, 84, fixed under the head part 103 of the blades and whose ends proximal are articulated on the head arms 80.

This configuration allows the curvature of the back part and the head part to be adjusted more effectively than in the prior art by controlling it on two levels.

According to FIG. 3, the head arms 80 are mounted in pairs on a head shaft 85 rotatably mounted on the chassis 30 and actuated by a pusher 86 articulated on the movable rod 71 of the head jack 70.

The legs 83, 84 are connected two by two by transverse beams which allows to stiffen the base in the back and head part.

The link 81 located in the back part located between the fixed point of the central part and the link of the head part will allow the back part to be hollowed out when the arm 80 is raised to raise the back and head part. .

FIG. 4 represents an embodiment for which the link 81 is not articulated directly on the arm 80 but is articulated on an intermediate plate 130 shown more particularly in FIGS. 5 and 6. The plate 130 comprises a locking device on the arm 80, here constituted by a screw clamping means 131 and plywood 132 clamping parts of slides of the arm 80.

This adjustment device adapted to slide and lock on the arm makes it possible in particular to refine the point of action of the back link on the blade 10.

As shown more particularly in FIG. 2, on the foot part side, according to the example shown, the blades are deformed by means of a foot jack 40 actuating in rotation rotary foot arms 50 connected to the foot part 101 of the blades by slides 51 rotatably mounted at the end of the foot arm and slidingly mounted on slides 52 parts of lateral edges 61 of a frame 60 for holding the foot part of the blades flat.

This configuration keeps the leg portion flat which makes the base more ergonomic.

To support the blades at said intermediate part and soften the curvature of the blades, rods 53, comprising a proximal end rotatably mounted on an intermediate part of the foot arms 50 and a distal end rotatably mounted on a tab 54 fixed under the blades 10, grow under the blades in an intermediate part between the foot part 101 of the blades and the central part 102 of the blades.

According to Figure 3, the foot arms 50 are mounted in pairs on a foot shaft 55 rotatably mounted on the frame 30 and actuated by a pusher 56 articulated on the movable rod 41 of the foot cylinder 40, which constitutes a device for robust and efficient operation.

Still in FIG. 3, the legs 54 and the legs 81, 84 are fixed under transverse beams 57, 87, 88 which connect the blades 10 to stiffen the bed base under the slats.

The bed base of the example thus comprises a first jack or head jack 70 acting on first arms 80 called head arms on which are articulated first and second links 81, 82, the first links 82 being rotatably mounted on first legs 84 at the head of the bed base, the second links 81 being rotatably mounted on second legs 83 at the back of the bed base.

It comprises a second jack or foot jack 40 on the foot side actuating second arms 50 called foot arms on which are articulated third links 53 rotatably mounted on third legs 54 on the foot side and on which are sliders 51 located at the free end arms and sliding on slides under a frame 60.

According to the example, the jacks 40, 70 are electric jacks comprising a cylinder 44, 74 and an electric motor 43, 73. The end of the cylinders of the jacks 40, 70 is mounted on one or more axes of rotation 42, 72 integral with the chassis.

Still according to FIG. 3, the motors 43, 73 of the jacks are connected by electrical cables 122, 123 to an electronic control unit secured to the chassis but shown here discarded for the purposes of the diagram.

The control unit receives commands for tilting the foot and head parts of a remote control 121. This remote control may include up-down buttons 121a for the feet and the head and / or may include pre-programmed buttons 121b for given positions. . The link between the control unit which interprets the signals received from the remote control and provides the electrical power necessary to operate the jacks can be a wired, infrared or digital radio link such as bluetooth or any other link usable in the field.

The control unit 120 may itself have control buttons or be blind.
