Joint fitting

Abstract

Hinge fitting for swivelable elements like for example arm rests, head portions of furniture for sitting or lying, and the like, comprising a swivel element which has a bore for receiving a hinge pin, and a holding element with a circular recess, in which a clamping disc on the hinge pin is rotatably arranged, wherein the clamping disc allows a rotational movement in a rotation direction relative to the holding element and blocks a rotational movement in the opposite direction, and wherein on the side of the swivel element there is provided at least a spring element, which presses the swivel element in axial direction of the hinge pin against the clamping disc.

1 . Hinge fitting for swivelable elements like for example arm rests, head portions of furniture for sitting or lying, and the like, comprising
 a swivel element which has a bore for receiving a hinge pin, and   a holding element with a circular recess,   in which a clamping disc on the hinge pin is rotatably arranged,   wherein the clamping disc allows a rotational movement in a rotation direction relative to the holding element and blocks a rotational movement in the opposite direction, and   wherein on the side of the swivel element there is provided at least a spring element, which presses the swivel element in axial direction of the hinge pin against the clamping disc.   
     
     
         2 . Hinge fitting according to  claim 1 , wherein a sliding disc is arranged between clamping disc and swivel element. 
     
     
         3 . Hinge fitting according to  claim 1 , wherein the spring element is formed as a plate spring. 
     
     
         4 . Hinge fitting according to one of  claim 1 , wherein the hinge pin has at both ends a diameter enlargement for holding and supporting the spring element. 
     
     
         5 . Hinge fitting according to  claim 2 , wherein clamping elements are formed in the recesses of the clamping disc as cylindrical clamping pins. 
     
     
         6 . Hinge fitting according to  claim 5 , wherein on the outer circumference of the holding element along the circumference there is formed a recess predetermining the swivel area, into which recess a protrusion engages at the swivel element or a protrusion is formed at the holding element which engages a corresponding recess at the swivel element. 
     
     
         7 . Hinge fitting according to  claim 6 , wherein the protrusion is formed at a spacer plate which is arranged between two swivel elements. 
     
     
         8 . Hinge fitting according to  claim 1 , wherein on a side of the holding element a covering disc is provided for covering a clamping portion and the swivel element is arranged on the opposite side of the holding element. 
     
     
         9 . Hinge fitting according to  claim 8 , wherein the clamping disc slidingly abuts with its outer circumference at the inner circumference of the recess of the holding element. 
     
     
         10 . Hinge fitting according to  claim 9 , wherein on the outer circumference of the clamping disc wedge-shaped recesses are arranged, in which in each case a clamping element is arranged, which can engage with the inner circumference of the recess for blocking the clamping disc relative to the holding element. 
     
     
         11 . Hinge fitting according to  claim 10 , wherein the clamping elements are acted upon in blocking direction by means of a spring element. 
     
     
         12 . Hinge fitting according to  claim 1 , wherein the holding element is provided with a fixing means for a further component part. 
     
     
         13 . Hinge fitting according to  claim 1 , wherein the swivel element for fixing a component part to be swiveled is formed in a different way than the holding element.
