Joint arrangement for an orthosis of an extremity joint and orthosis with such a joint arrangement

摘要

The present invention relates to a joint arrangement (10; 110; 210; 310) for an orthosis of an extremity joint, comprising a first joint leg (12; 112; 212; 312) with an elongated first leg section (14) and a first head section (16; 116 ; 216; 316), and a second joint leg (18; 118; 218; 318) with an elongated second leg portion (20) and a second head portion (22; 122; 222; 322), the first joint leg (12; 112 ; 212; 312) and the second joint leg (18; 118; 218; 318) in the area of the first and second head section (16; 116; 216; 316; 22; 122; 222; 322) at least partially overlapping and furthermore in such a way are articulated with one another so that the joint legs (12; 112; 212; 312; 18; 118; 218; 318) can be pivoted to one another in a pivot plane, and furthermore a recess in the first head section (16; 116; 216; 316) (24; 124; 224; 324) and on the second head section (22; 122; 222; 322) a guide body (26; 126; 226; 326) is provided, the guide body (26; 126; 226; 326) being arranged in the recess (24; 124; 224; 324) and movable relative thereto, the recess (24; 124; 224; 324) being a The inner contour and the guide body (26; 126; 226; 326) have an outer contour which are designed in such a way that, during pivoting of the joint limbs (12; 112; 212; 312; 18; 118; 218; 318) with respect to one another, the recess (24 ; 124; 224; 324) relative to the guide body executes a rotational and translational movement in which it is positively guided around the guide body (26; 126; 226; 326) and at least in phases a predetermined section of the inner contour (64) on a predetermined section the outer contour (66) rolls.
