DOOR HINGE, AND ALSO THE INTERNAL DOOR Russian patent published in 2019 - IPC E05D3/06 

FIELD: construction.

SUBSTANCE: invention relates to door hinge (3) with part (7) for door frame and part (8) for leaf, which are connected to each other through first hinge bracket (4) and second hinge bracket (5), moreover, door hinge (3), starting from the closed position, has opening angle of at least 135°on reaching the maximum open position, and moreover, when moving the opening from the closed position to the open position, hinged brackets rotate (4, 5) with respect to part (7) for door frame in first direction of rotation and part (8) for leaf in relation to hinge brackets (4, 5) in the same direction of rotation as well, moreover, hinge brackets (4, 5) form 4-axis hinge device in which first hinge bracket (4) with slewing capacity around first axis (9a) of part for door frame is fixed to part (7) for door frame, and also with slewing capacity around first axis (10a) of part for door leaf fixed on part (8) for leaf, and wherein second hinge bracket (5) can be rotated around second axis (9b) onto part (7) for door frame, and also with slewing capacity around second axis (10b) is fixed on part for leaf, and that both hinged brackets (4, 5) are not connected directly to each other. According to the invention, first and second hinge bracket (4, 5), respectively, at their ends are attached to axes (9a, 9b) of part for door frame, and also to axes (10a, 10b) of part for leaf and between ends thereof in the middle section have a U-shape, and for first hinge bracket (4), starting from first connecting line between first axis (10a) of part for leaf and first axis (9a) parts for door frame, the maximum defined perpendicular to the first connecting line to the central section of the distance (a₂) is at least a multiple of 0.5 distance (a1) between first axis (9a) of door frame part and first axis (10a) of part for leaf, and moreover for second hinge bracket (5), starting from second connecting line between second axis (10b) of part for leaf and second axis (9b) of part for door frame, maximum defined perpendicular to the second connecting line to the central section of the distance (b₂) is at least a multiple of 0.5 distance (b₁) between second axis (9b) of part for door frame and second axis (10b) of part for leaf. Further invention relates to an interior door with door frame (1), door leaf (2) and door hinge (3).

EFFECT: proposed door hinge design.
