A locking mechanism (10) for a hinge (4) is disclosed. A latch member (11) engages with a lip (12). A positive drive means (20, 23, 24, 41) enables the latch member to be driven into and out of engagement with the lip. The driven engagement when the hinge is used in relation to columns (1, 101) prevents small movements at the hinge being magnified into large movements at the end of the column members. The driven dis-engagement enables the hinge to be opened notwithstanding mechanical loads, corrosion, insect nests and similar obstacles. The drive means preferably takes two forms, namely threaded fasteners (20, 23, 24) and a spring loaded rotatable actuator (41) with ramped surfaces (48, 49) which male with ramped surfaces (61, 62) on the latch member (11).

A connecting device, in particular for installing at least one opening stay on a window leaf has a rail, which can be guided as far as possible in the direction of the first longitudinal axis thereof into a groove of the connecting device. The groove engages at least in sections behind the rail. The blocking of the longitudinal displaceability of the rail in the groove is guaranteed at least counter to the first longitudinal direction by a projection connected to the rail, which projection engages in a recess in the region of the groove. The projection is held in the installed position of the connecting device by a spring element in the recess. A spring element is arranged on the rail preferably in a limited movable manner. Alternatively or in addition, the connecting device can comprise a cap which holds the projection in the installed position of the connecting device indirectly and/or directly at least partially in the recess.

A hinge includes a first end plate, a second end plate and at least one inner plate positioned between the first end plate and the second end plate. The first end plate is connected to the at least one inner plate by a first pin that extends through the first end plate and the at least one inner plate. The second end plate is connected to the at least one inner plate by a second pin that extends through the first end plate and the at least one inner plate. The first end plate is rotatable relative to the at least one inner plate about a first pivot axis defined by the first pin. The second end plate is rotatable relative to the at least one inner plate about a second pivot axis defined by the second pivot pin.

The invention relates to a hinge (1) for connecting a movable part (T) to another part (R), wherein the hinge (1) has four levers (2, 3, 4, 5) with seven points of rotation (25, 26, 27, 28, 29, 30, 31), and six (25, 26, 27, 28, 30, 31) of the seven points of rotation (25, 26, 27, 28, 29, 30, 31) are arranged axially symmetrically in relation to a mirror axis (S), which runs through one (29) of the seven points of rotation (25, 26, 27, 28, 29, 30, 31), and two (25, 26) of the six symmetrically arranged points of rotation (25, 26, 27, 28, 30, 31) can be fixed on the movable part, and two (27, 28) of the six symmetrically arranged points of rotation (25, 26, 27, 28, 30, 31) can be fixed on the other part, in each case by means of an attachment (6), and the attachments (6) secure the relative position of the in each case two points of rotation (25, 26; 27, 28) in relation to one another, and one (25) of the two points of rotation (25, 26) secured by means of a first of the two attachments (6) is connected, by means of one lever (3) of the four levers (2, 3, 4, 5), to one (30) of the two symmetrically arranged points of rotation (30, 31) which are present outside the attachment (6), and the other (26) of the two points of rotation (25, 26) secured by means of the first attachment (6) is connected, by means of a further lever (5) of the four levers (2, 3, 4, 5), to the other one (31) of the two symmetrically arranged points of rotation (30, 31) which are present outside the attachments (6), wherein the further lever (5) also incorporates the point of rotation (29), through which the mirror axis (S) runs, wherein, in the closed state, there is an enclosed angle of less than 155 between a connecting line between the point of rotation (29) having the mirror axis (S) and a point of rotation (31) outside the attachments (6) and a connecting line between the point of rotation (29) having the mirror axis and the point of rotation (26) at the attachment (6) for a lever (5).

An integrated hinge for a cabinet is described. The integrated hinge includes a central portion having a first outer edge and a second outer edge. The integrated hinge includes a first lateral portion having a first inner edge. The integrated hinge includes a second lateral portion having a second inner edge. A hinge pin rotatably connects the central portion, the first lateral portion, and the second lateral portion. The first outer edge and the first inner edge are angled toward the hinge pin at a positive angle relative to the hinge pin, and the second outer edge angled and the second inner edge are angled toward the hinge pin at a negative angle relative to the hinge pin.
