Abstract
Abstract There is described a frame comprised of sectional shapes and comprising assembly means joining same in every junction location thereof, and hanging means, the sectional shapes each having two lengthwise projections wherebetween the articles to be framed are arranged, said means being comprised in each frame corner, on the one hand of an element with two legs the angle of which is equal to the frame inner angle as formed by two sectional shapes where same join, each said legs being so designed as to cooperate by interlocking with the projection from one both said sectional shapes, and on the other hand of means so arranged on the legs as to fix each leg relative to the corresponding projection.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
Frame comprised of sectional shapes and comprising assembly means joining said sectional shapes in every junction location thereof, and hanging means, in which said frame sectional shapes each have two parallel lengthwise projections, facing inwardly relative to the frame and wherebetween the articles to be framed are arranged, said assembly means being comprised in the inner side of each frame corner, on the one hand of an element with two legs the angle of which is equal to the inner angle of the frame as formed by two sectional shapes in the junction location thereof, each said legs having a substantially U-shaped cross-section to provide two flanges, being so designed as to cooperate by interlocking with that projection from both said sectional shapes nearest the frame back, and on the other hand of means so arranged on the legs as to fix at least the one flange of each leg nearest the frame back relative to the corresponding projection.
Claim 2
Dependent Claim
159 words
Frame comprised of sectional shapes and comprising assembly means joining said sectional shapes in every junction location thereof, and hanging means, in which said frame sectional shapes each have two parallel lengthwise projections, facing inwardly relative to the frame and wherebetween the articles to be framed are arranged, said assembly means being comprised in the inner side of each frame corner, on the one hand of an element with two legs the angle of which is equal to the inner angle of the frame as formed by two sectional shapes in the junction location thereof, each said legs having a substantially U-shaped cross-section to provide two flanges, being so designed as to cooperate by interlocking with that projection from both said sectional shapes nearest the frame back, and on the other hand of means so arranged on the legs as to fix at least the one flange of each leg nearest the frame back relative to the corresponding projection.
Claim 3
Dependent Claim
15 words
Frame as defined in claim 1, in which the sectional shapes have the same cross-section.
Claim 4
Dependent Claim
15 words
Frame as defined in claim 1, in which said elements with two legs are identical.
Claim 5
Dependent Claim
35 words
Frame as defined in claim 2, which is comprised of four sectional shape lengths, equal two by two, the ends of which are mitre-cut, said elements with two legs being in the shape of corner-pieces.
Claim 6
Dependent Claim
30 words
Frame as defined in claim 1, in which said hanging means are comprised of at least one member provided on each said two-leg elements and fixed relative to said element.
Claim 7
Dependent Claim
69 words
Frame as defined in claim 5, in which each said two-leg elements has two members comprising said hanging means, said members in lug shape being arranged on the free ends of the legs, being comprised of an extension of the U web and forming an angle therewith to face inwards relative to the frame, each said lugs having an opening allowing securing therein the end of a hanging cable.
Claim 8
Dependent Claim
78 words
Frame as defined in claim 1, in which said means provided to fix at least one said flanges from each said element legs relative to the corresponding projection, are comprised of at least one pressure screw arranged in a screwthreaded hole provided in that flange nearest the frame back and having an axis substantially at right angle thereto, said pressure screw being so designed as to bear on that side of the projection facing the flange under consideration.
Claim 9
Dependent Claim
35 words
Frame as defined in claim 7, in which said flange has in the location of said tapped hole, an overthickness comprising a reinforcement for the element, said overthickness being provided on the flange outer side.
Claim 10
Dependent Claim
44 words
Frame as defined in claim 8, in which said two-leg elements are made from cast metal, said lugs as well as the element reinforcements being directed along the same direction and in parallel relationship with the bisectrix of the angle formed by both legs.
Claim 11
Dependent Claim
129 words
Frame as defined in claim 1, in which said sectional shapes have in parallel relationship with that projection nearest the frame back, a rib facing inwards relative to the frame and lying opposite the other projection, the spacing between said first projection and said rib being larger than the thickness of the flanges from the legs of said elements, and said spacing is such that when one flange of said legs bears on the projection, the other flange of the legs bears on the rib, while the size of the rib as considered at right angle to the sectional shape lengthwise axis is such that said means provided to fix at least the one flange of each leg relative to the corresponding projection be released relative to said rib.
Claim 12
Dependent Claim
58 words
Frame as defined in claim 1, in which the sectional shapes are made from synthetic material, such as a plastic material, each sectional shape including a rigid reinforcing metal sectional shape so arranged as to follow the size of that projection nearest the frame back and to grip same to prevent distortions of the synthetic material sectional shapes.
Claim 13
Dependent Claim
67 words
Frame as defined in claim 11, in which the synthetic material being used is polymethyl-methacrylate, notably known under the name "Plexiglass", and including between both projections from each sectional shape, over the whole length thereof, a strip from opaque material the width of which corresponds to the spacing between both said projections, said strip being provided to conceal the corresponding edge of the articles to be framed.
