  • Patent number: 11839304
    Abstract: A pivot fitting has a first lever mounted such that is pivotable out of a starting position about a force-transmitting shaft serving as an axis of rotation in relation to the shaft. The fitting has a clamping mechanism fixing the first lever in different angular positions relative to the shaft. The clamping mechanism has a toothed-ring disc positioned on the shaft and has an outer toothing structure formed on the outer periphery, a catch mounted in a pivotable manner on the first lever and is loaded in the direction of the outer toothing structure and, in a latching position, is in engagement with the outer toothing structure.

  • Publication number: 20210007487
    Abstract: A pivot fitting for movable furniture parts on pieces of furniture, has a first lever and a second lever that are mounted to pivot about a common axis from a basic position through a predetermined angle, a clamping mechanism with which the two levers are fixable relative to each other at different angular positions within the predetermined angle. The clamping mechanism includes a toothing attached in a rotationally fixed manner to the second lever, at least one catch pivotally mounted on the first lever and loaded in the direction of the toothing, the catch engaging with the toothing in a detent position, a control disc mounted to pivot about the common axis, with which control disc the at least one catch can be disengaged from the toothing when the pretermined angle has been passed in an adjusting direction from the basic position so that when the catch is disengaged from the toothing, the two levers can be pivoted back into the basic position when the predetermined angle is passed in a resetting direction.

  • Patent number: 9790985
    Abstract: A pivoting fitting (1) comprises a first tab (2) and a second tab (3) which are mounted so as to be rotatable relative to each other about an axis (6), and a locking mechanism having at least one pawl (5) and toothing (4), wherein the pawl (5) can be engaged in the toothing in a plurality of positions and permits a pivoting movement of the first tab (2) with respect to the second tab (3) in a first direction and blocks movement in an opposing direction, and wherein at least one control element (14) is provided to disengage the at least one pawl (5) from the toothing (4) and then to pivot the first tab (2) with respect to the second tab (3) in the second direction through an angle, wherein the at least one pawl (5) is retained by a spring element (9) in a position engaged in the toothing (4), wherein the spring element (9) is at least partially made from an elastomer material. In this way, the pivoting fitting (1) can be pivoted with little noise.
