Problems solved by technology

[0007] In this prior art mentioned above, it has proven disadvantageous that the release torque of this frictionally constrained solution for overload protection is very low, in particular in the range of 8Nm to 15Nm, which often leads to pivoting of the fittings undesired release of

Embodiment Construction

[0046] In the following descriptions of figures, terms such as top, bottom, left, right, front, rear, etc. refer only to the pivot fittings, levers, claw joints, claw plates, shells selected in the corresponding figure Exemplary representation and location of body etc. These terms are not to be interpreted as limiting, ie these references can vary due to different working positions or mirror-symmetrical layouts, etc.

[0047] exist Figure 1-Figure 4 , reference numeral 1 designates as a whole an embodiment variant of the pivot fitting according to the invention. Such a pivoting fitting 1 is used in particular to enable a pivoting movement of movable furniture parts on furniture such as, for example, armrests 103 or backrests, headrests or footstools such as Figure 11-Figure 13 shown.

[0048] like Figure 1 to Figure 4 As shown, the pivot fitting 1 has a first lever 2 and a second lever 3 . The two levers 2 , 3 are mounted so as to be pivotable relative to each other o...

Abstract

The invention relates to a pivot fitting, in particular for movable furniture parts on upholstered furniture, said pivot fitting having: a first lever (2) and a second lever (3) which are pivotably mounted with respect to one another about a common axis (D) out of a starting position about a predetermined angle ([alpha]); a clamping mechanism using which the two levers (2, 3) can be fixed at different angular positions within the predetermined angle ([alpha]) relative to one another counter to a torque acting in the restoring direction (R) and, when the clamping or locking mechanism (23) is deactivated, can be pivoted in the restoring direction (R); and an overload coupling using which the first lever (2) can be pivoted in the restoring direction (R) relative to the second lever (3) when apredetermined torque is exceeded when the clamping mechanism (24) is activated, the overload coupling being a claw clutch (4) which is arranged as a structural unit between the first lever (2) and the second lever (3). The invention also relates to an item of furniture.

Description

technical field [0001] The invention relates to a pivot fitting according to the preamble of claim 1 and to a piece of furniture with such a pivot fitting. Background technique [0002] A common type of pivot fitting has two levers which can be fixed relative to each other by means of a clamping mechanism by which the two levers can resist a torque acting in the return direction within a predetermined angle are fixed in different angular positions relative to each other, and the two levers can pivot in a return direction when the clamping mechanism is released. [0003] Such a universal pivot fitting is known, for example, from DE 10 2011 017 301 B4. This pivoting fitting has proven useful. [0004] In order to avoid damage due to overloading of such a pivot fitting, in the pivot fitting according to DE 10 2011 017 301 B4 the toothed disk of the clamping mechanism is held between two friction disks. [0005] The chainring itself has an external toothing into which the paw...
