[0093] According to the figures, two functional fittings 2, 4 coaxially arranged along the central longitudinal axis of a bed frame 6 are usually mounted below and inside the bed frame 6 for a box spring bed.
[0094] The box spring bed, more precisely its bed frame 6, comprises two frame side parts 6.1, 6.2 equally spaced to one another in a transverse direction parallel to a longitudinal axis extending centrally between them as well as a head frame part 6.3 and a foot frame part 6.4 at a head end and at a foot end transversely extending between these frame side parts 6.1, 6.2 and connecting them so that a circumferentially closed rectangular bed frame 6 is formed.
[0095] A central plate 8, transversely extending between these frame side parts 6.1, 6.2 is attached on the upper side of this bed frame 6 approximately in the middle. This central plate 8 defines the lying plane of the bed that preferably extends horizontally in a mounting position. A head plate 12 is pivotally attached at a head end to this central plate and a foot plate 14 at a foot end by hinges 10. For a better representation, the central plate 8, the head plate 12 and the foot plate are designed as transparent plexiglass plates but in practice they are rather designed as wood plates.
[0096] The foot plate 14 is again divided into an upper leg plate 14.1 that faces the central plate 8 as well as into a slightly longer lower leg plate 14.2 that is facing away from the central plate. The upper leg plate 14.1 and the lower leg plate 14.2 are again pivotally connected with one another by hinges 10.
[0097]
[0098] Each functional fitting 2, 4 comprises a longitudinal beam 2.1, 4.1 configured as a rectangular steel profile that is made of lacquered steel and that centrally extends under the bed frame 6 in the bed longitudinal axis. Mounting brackets 2.2, 4.2 are attached at its respectively outer front end; they are set on the upper side of cross beams 6.5, 6.6 transversely attached between the side parts 6.1, 6.2 and attached on the inner side on the head frame part 6.3 and on the foot frame part 6.4, respectively with horizontal legs bearing on the upper side on the cross beams 6.5, 6.6 and vertical legs in abutment against them on the inner side.
[0099] Bracket profiles 2.3, 4.3 extending on both sides respectively transversely to the longitudinal axis of the longitudinal beam are attached at the inner front end of the longitudinal beams 2.1, 4.1, bracket profiles the inner legs of which are laterally attached to the longitudinal beams 2.1, 4.1 and the horizontal mounting legs of which extend transversely to the longitudinal axis of the longitudinal beams 2.1, 4.1 and can be screwed to the lower side of the central plate in mounting position in order to thus connect the functional fittings 2, 4 on the one hand with the bed frame 6 on the inner side and simultaneously to secure the central plate 8 against sagging in the middle, whereto the bracket profiles 2.3, 4.3 are preferably configured as steel profiles. For stability reasons, the whole functional fitting 2, 4 is made from angled or drawn steel profiles.
[0100] The rear motor end of a linear drive 2.4, 4.4 is rotatably hinged at the outer end of the functional fittings 2, 4 respectively as close to the outer and as close to the lower end of the longitudinal beams 2.1, 4.1 as possible. The inner end of each linear drive 2.4, 4.4 is formed by a motorized adjustable lifting tube rotatably hinged on a transverse beam of a lift-up frame 2.5, 4.5.
[0101] Each lift-up frame 2.5, 4.5 is rotatably attached with a lower end to the longitudinal beam 2.1, 4.1 and widens at its upper end in transverse direction for increasing the contact surface below the head plate 12 and the foot plate 14 or the lower leg plate 14.2.
[0102] Each lift-up frame 2.5, 4.5 can be formed by two profile brackets connected with each other that have a lower attachment end for the lateral hinging to the respective longitudinal beam 2.1, 4.1, thus enclose it on both sides with an axis arranged therebetween and extend in longitudinal direction from this lower attachment end parallel to one another on both sides of the longitudinal beam 2.1, 4.1, first merge in longitudinal direction into an enlarged portion in which the space to the profile brackets widens and merge at their free upper end again into end portions that extend parallel to one another.
[0103] The lift-up frame 2.5 is provided with rollers at the free upper end on the end portions spaced from each other in transverse direction, rollers that roll on the lower side of the head plate 12 when displacing the lift-up frame 2.5 from the lowered rest position to the raised lift position. The lifting tube of the linear drive 2.4 engages a cross beam that extends between the widened portions of both profiles of the lift-up frame 2.5.
[0104] The lift-up frame 4.5 at the foot part is structured similarly to the lift-up frame for the head part with the difference that, instead of rollers, it includes two bracket profiles at the end portions that are screwed on the lower side of the lower leg plate 14.2. Again, the lifting tube of the linear drive 4.4 engages on a fork head that is attached to a cross beam that extends between the widened portions of both profiles of the lift-up frame 4.5.
[0105] According to the invention, the functional fittings 2, 4 can also be suitably designed in that the linear drive is attached with its lower motor end in the mounting position, is thus integrated into the bed frame 6, as far as possible on the outside on the longitudinal beam 2.1, 4.1, is thus hinged and rotatably engages the relatively movable lifting tube as close as possible at the upper end on the lift-up frame 2.5, 4.5 that is hinged with its lower attachment end by being rotatably oriented inwards on the longitudinal beam 2.1, 4.1 in order thus realize an optimal development of force and to have to provide a lowest possible motor power.
