Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A hinge assembly for butt-closing door leaves comprising: a. a frame fixture element, a door leaf fixture element and an independent connecting mechanism, b. each said fixture element including a guide means, c. said connecting mechanism including a fixed portion, a pivoting portion that pivots about a pivotal axis located on said fixed portion and connecting means which engage said guide means on each of the fixture elements, d. said connecting means being detachably lockable with said guide means and being adjustably disposed with respect to the guide means on each of the fixture elements so that the independent connecting mechanism is displaceable with respect to the frame fixture and door leaf fixture elements.
Claim 2
Dependent Claim
114 words
A hinge assembly for butt-closing door leaves comprising: a. a frame fixture element, a door leaf fixture element and an independent connecting mechanism, b. each said fixture element including a guide means, c. said connecting mechanism including a fixed portion, a pivoting portion that pivots about a pivotal axis located on said fixed portion and connecting means which engage said guide means on each of the fixture elements, d. said connecting means being detachably lockable with said guide means and being adjustably disposed with respect to the guide means on each of the fixture elements so that the independent connecting mechanism is displaceable with respect to the frame fixture and door leaf fixture elements.
Claim 3
Dependent Claim
39 words
