[0018] The legend:

[0019] 1the enclosure (the fixed part or the cover plate),

[0020] 2the lever (the rotation part),

[0021] 3the lever rotation axis,

[0022] 4the mounting axis of the leg pull stud,

[0023] 5the bores for mounting to the movable part of the transformer bed (the mounting of the bed deck),

[0024] 6the positioning pins,

[0025] 7the stretching elastic element,

[0026] 8the compression elastic element,

[0027] 9the mounting axis of the stretching elastic element (8) to the lever (2),

[0028] 10the mounting axis of the stretching elastic element (7) to the lever (2),

[0029] 11the mounting axis of the stretching elastic element (8) to the enclosure (1),

[0030] 12the mounting axis of the compression elastic element (8) to the enclosure (1),

[0031] 13the split in the enclosure (1) through which the mounting axis (9) of the compression elastic element (8) to the lever (2) passes,

[0032] 14the axle box welded (press-fitted) or otherwise rigidly fixed to the enclosure (1).

[0033] 15the mating spindle rigidly fixed (welded, press-fitted) to the lever (2).

[0034] The rotation mechanism of the transformer bed consists of the enclosure (1), the lever (2) mounted with the ability to rotate around the rotation axis (3) on the enclosure (1) and representing an L-shaped swivel plate with the bores (5) for the mounting to the movable part of the transformer bed, the stretching elastic element (springs) (7), and the compression elastic element (gas cylinder) (8).

[0035] The position of the bores (5) on the lever (2) can vary, and the lever (2) can be fixed on the movable part/component (frame/deck/shell/carcass) of the transformer bed with the help of any fasteners (self-tapping screws, screw bolts, screw staves, etc.).

[0036] The enclosure is made of a base plate and a cover between which the (fixed) mounting axes (11, 12) of the stretching (7) and compression elastic elements (8) are mounted. The base plate and the cover are connected to each other with the screwed joints. The base plate is mounted to the fixed part of the transformer bed with self-tapping screws or any other standard fasteners (self-tapping screws, drywall screws, screw bolts).

[0037] The rotation axis (3) is made as the axle box (14) welded (press-fitted) or otherwise rigidly fixed to the enclosure cover (1), into the bore of which the mating spindle (15), which is welded (press-fitted) to the lever 2, engages.

[0038] The design of the lever (2) as an L-shaped swivel plate facilitates the installation of the deck (frame/shell/carcass) to the rotation mechanism of the transformer bed.

[0039] The stretching elastic element (7) is fixed with one end inside of the enclosure (1) with the help of the mounting axis (11) and fixed to the lever (2) with the other end via the mounting axis (10), wherein this end of the stretching elastic element (7) passes through the bore formed by the base plate and enclosure cover (1) in its folded state.

[0040] The compression elastic element (8) is fixed with one end inside of the enclosure (1) with the help of the mounting axis (12), and fixed to the lever (2) with the other end via the mounting axis (9), wherein there is the split (13) on the enclosure cover, along which the mounting axis (9) of the compression elastic element (8) moves.

[0041] The enclosure cover (1) can have the mounting axis (4) of the leg pull stud (it is a component of the finished product), its presence/absence does not influence the functionality of the rotation mechanism itself, and there can be at least one positioning pin (6) made on the enclosure base plate (1) facilitating the accurate installation of the rotation mechanism to the transformer bed (article) and bearing the weight of the deck (frame/shell/carcass).

[0042] The rotation mechanism is used in the following way.

[0043] Two rotation mechanisms are provided for one bed.

[0044] The enclosure of the rotation mechanism is mounted to the fixed part of the transformer bed, for example, serving as a wardrobe enclosure, and the lever of the rotation mechanism is mounted to the bed deck.

[0045] To modify the transformer bed (furniture), for example, the wall bed, from the wall position to the bed position, the deck is rotated with a force directed down and forwards to the user. The rotation mechanism is activated by shifting/rotation of the lever that impacts the stretching elastic element by stretching it and the compression elastic element by pushing the piston rod of the gas cylinder decreasing its total length, and the mounting axis (9) moves inside of the split in this case.

[0046] To return to the wall position, the reverse operations should be done. The deck should be rotated upside, and at the same time, the rotation mechanism is activated by shifting/rotation of the lever that is impacted by the stretching and compression elastic elements which constrict (tighten) and expand (push out) correspondingly to balance the weight of the deck and facilitate folding of the bed for the user by decreasing the applied efforts to the acceptable level (not more than 80 N). In this case, the mounting axes (9 and 10) rotate around the rotation axis of the lever (axis 9 moves inside of the split). The claimed rotation mechanism has a simple design, operational reliability, and usability.
