Abstract
Abstract Each member of an artificial joint comprises a toothed sector pivoting about a pin. These toothed sectors are in engagement with one another and are mounted between two parallel side plates separated by two spacers. Openings passing through these side plates are angularly distributed about each axis of pivoting and are adapted to selectively receive stops formed by pins which delimit the sectors of freedom of the members about the axes of pivoting. Each of these stops is associated with an apertured tongue which extends perpendicular to the axis of the pin and permits bolting the stop to the center of pivoting of its member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A joint device for connecting first and second members of an artificial joint, the first and second members being provided to affix the artificial joint to the human body, the joint device comprising: first and second supporting side plates disposed in parallel and fixedly coupled to one another; first and second pivot pins extending between said first and second side plates; first and second semi-circular toothed sectors, one mounted coaxially to each pivot pin, said toothed sectors being in engagement with one another and each being fixedly associated with one of said first and second members; and adjustable stop means extending into the path of at least one of said first and second members to define a sector of freedom for said at least one member, at least one of said side plates comprising positioning openings angularly distributed about the axis of at least one of said pivot pins and two angular stops which are angularly adjustable relative to the axis of said at least one pivot pin, each of said stops comprising a rod extending through a positioning opening of said at least one side plate, said rod being integral with a small plate which has a plane perpendicular to a longitudinal axis of said rod, said small plate including means for connecting said small plate to the axis of said at least one pivot pin.
Claim 2
Dependent Claim
227 words
A joint device for connecting first and second members of an artificial joint, the first and second members being provided to affix the artificial joint to the human body, the joint device comprising: first and second supporting side plates disposed in parallel and fixedly coupled to one another; first and second pivot pins extending between said first and second side plates; first and second semi-circular toothed sectors, one mounted coaxially to each pivot pin, said toothed sectors being in engagement with one another and each being fixedly associated with one of said first and second members; and adjustable stop means extending into the path of at least one of said first and second members to define a sector of freedom for said at least one member, at least one of said side plates comprising positioning openings angularly distributed about the axis of at least one of said pivot pins and two angular stops which are angularly adjustable relative to the axis of said at least one pivot pin, each of said stops comprising a rod extending through a positioning opening of said at least one side plate, said rod being integral with a small plate which has a plane perpendicular to a longitudinal axis of said rod, said small plate including means for connecting said small plate to the axis of said at least one pivot pin.
Claim 3
Dependent Claim
105 words
A joint device according to claim 1, wherein said at least one pivot pin is traversed by a cylindrical axial opening, one end of which is tapered, said small plate being provided with an opening for coinciding with the other end of said cylindrical axial opening, and a securing member passing through said openings and comprising a pin element provided at one end with a head engaging against said small plate, and, at the other end thereof, with a tapered part corresponding to that of the cylindrical axial opening, two diametral slots providing four radially-extending resilient members in said tapered part of said securing member.
Claim 4
Dependent Claim
46 words
A joint device according to claim 2, wherein each said pivot pin comprises a tubular element inserted through two coaxial openings, one in each side plate and comprises a tubular part, having a tapered end, said tapered end being surrounded by an annular axially retaining flange.
Claim 5
Dependent Claim
24 words
A joint device according to claim 1, wherein said adjustable stop means extends into a path of each of said first and second members.
