Abstract
Abstract A system for a mono-axial and a duo-axial orthesis joint is created. The system comprises a first and a second post (1, 2), a mono-axial cover (21) and two duo-axial covers (3). The posts (1, 2) each have a shaft bore (4, 5) at a first end thereof and toothed portions (6, 7) provided at the first ends of the posts (1, 2). One shaft bore (22) is provided in the mono-axial cover and two spaced shaft bores (3, 4) are provided in the duo-axial cover (3). The distance between the shaft bores is so that in the duo-axial construction both toothed portions (6, 7) engaged each other.

Claim 1
Independent Claim
265 words
An orthesis joint system for constructing a mono-axial orthesis joint or a duo-axial orthesis joint, the system comprising: a first post having two ends and a first shaft bore and a first toothed portion at one of said ends, a second post having two ends and a second shaft bore and a second post having two ends and a second shaft bore and a second toothed portion at one of said ends, a duo-axial cover means for constructing a duo-axial joint using said duo-axial cover means and said first and second posts, said duo-axial cover means comprising a third shaft bore and a fourth shaft bore, a first shaft extending through said third shaft bore and said first shaft bore for hingedly connecting said first post with said duo-axial cover means, and a second shaft extending through said fourth shaft bore and said second shaft bore for hingedly connecting said second post with said duo-axial cover means to assemble said duo-axial joint, said third shaft bore being spaced from the said fourth shaft bore for engagement of said first toothed portion with said second toothed portion in said assembled state, a mono-axial cover means alteratively engageable with said first and second posts, in lieu of said duo-axial cover means, for constructing a mono-axial joint using said mono-axial cover means and said first and second posts, a fifth shaft bore formed in said mono-axial cover means, and a third shaft extending through said fifth shaft bore and said first and second shaft bores for hingedly connecting said first and second posts to said mono-axial cover means.
Claim 2
Dependent Claim
265 words
An orthesis joint system for constructing a mono-axial orthesis joint or a duo-axial orthesis joint, the system comprising: a first post having two ends and a first shaft bore and a first toothed portion at one of said ends, a second post having two ends and a second shaft bore and a second post having two ends and a second shaft bore and a second toothed portion at one of said ends, a duo-axial cover means for constructing a duo-axial joint using said duo-axial cover means and said first and second posts, said duo-axial cover means comprising a third shaft bore and a fourth shaft bore, a first shaft extending through said third shaft bore and said first shaft bore for hingedly connecting said first post with said duo-axial cover means, and a second shaft extending through said fourth shaft bore and said second shaft bore for hingedly connecting said second post with said duo-axial cover means to assemble said duo-axial joint, said third shaft bore being spaced from the said fourth shaft bore for engagement of said first toothed portion with said second toothed portion in said assembled state, a mono-axial cover means alteratively engageable with said first and second posts, in lieu of said duo-axial cover means, for constructing a mono-axial joint using said mono-axial cover means and said first and second posts, a fifth shaft bore formed in said mono-axial cover means, and a third shaft extending through said fifth shaft bore and said first and second shaft bores for hingedly connecting said first and second posts to said mono-axial cover means.
