Abstract
Abstract The invention relates to a mounting for a door or window, especially an all-glass door or an all-glass window. A vertical frame piece provides a vertically extending receiving space accessible via a vertical slit for an anchor with an internal thread. A screw penetrating a hinge part is screwed into this thread. The anchor has a transverse dimension smaller than the width of the slit and a longitudinal dimension greater than the width of the slit. A friction drive member for the anchor is located in the slit and penetrated by the screw.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
A mounting for a covering for an opening, comprising: a vertical frame piece which provides a vertically extending receiving space, said space being accessible through a vertical slit; an anchor member located within said receiving space, said anchor member having an internal thread, a transverse dimension smaller than the width of the slit, and a longitudinal dimension greater than the width of the slit; a hinge attached to said anchor member via attaching means for engaging said internal thread; and a friction drive member which contacts said anchor member and is penetrated by the screw, said friction drive member comprising an elastomeric O-ring provided in the slit and an annular collar contacting the internal thread of said anchor member, said annular collar having an external diameter smaller than the width of the slit, wherein the sum of the thickness of the annular collar and the thickness of the O-ring is greater than the depth of the slit.
Claim 2
Dependent Claim
157 words
A mounting for a covering for an opening, comprising: a vertical frame piece which provides a vertically extending receiving space, said space being accessible through a vertical slit; an anchor member located within said receiving space, said anchor member having an internal thread, a transverse dimension smaller than the width of the slit, and a longitudinal dimension greater than the width of the slit; a hinge attached to said anchor member via attaching means for engaging said internal thread; and a friction drive member which contacts said anchor member and is penetrated by the screw, said friction drive member comprising an elastomeric O-ring provided in the slit and an annular collar contacting the internal thread of said anchor member, said annular collar having an external diameter smaller than the width of the slit, wherein the sum of the thickness of the annular collar and the thickness of the O-ring is greater than the depth of the slit.
Claim 3
Dependent Claim
19 words
A mounting according to claim 1, wherein the said anchor member has a cross section represented by a parallelogram.
Claim 4
Dependent Claim
29 words
