Abstract
A uniaxial orthopaedic hinge (1000, 2000) has a substantially circular body forming a recessed housing (1022, 2022). A back plate (1006, 2006) has an extension into a stub arm (1004, 2004) for attaching to the arm of an orthosis and is fixed to the recessed housing (1022, 2022). A locking plate (1008, 2008) also has an extension into a stub arm (1002, 2002) and is disposed in a parallel manner between the recessed housing (1022, 2022) and the back plate (1006, 2006). The circular recessed housing (1022, 2022) is provided with a recess (1100, 2100) housing a lock actuator (1102, 2102) having a latching dog (1126, 2126) and also fitted with a biasing leaf spring (1104, 2104). The latching dog (1126, 2126) co-operates with a latching hole (1128, 2128) in the locking plate (1008, 2008) when the hinge (1000, 2000) is in the fully extended position. A lifting cam (1110, 2110) underlies the lock actuator (1102, 2102)and has a cam lifting lever which extends through the face of the circular recessed housing (1022, 2022). The cam lifting lever is moved through about 90.degree. to release the latching dog (1126, 2126) so that the hinge (1000, 2000) may move with free or controlled motion. When the cam lifting lever is switched to the 'on' position, the latching dog (1126, 2126) is brought into contact with the locking plate (1008, 2008) under the influence of the spring (1104, 2104). The hinge (1000, 2000) moves freely unless it is fully extended, at which point the latching dog (1126, 2126) once again engages the locking plate (1008, 2008), locking the hinge mechanism (1000, 2000) in full extension.
