Abstract
The invention relates to a roof construction, assembled from aluminium alloy extrusions and sections which may be cut on site to the appropriate dimensions. There is a ring beam, made from a channel and a ridge member in the form of a central extruded aluminium alloy central box member, the channel and member being essentially of the same section. Thus a relatively small number of different extrusions are required.
Claims20
A conservatory roof construction comprising:
- (i) a ring beam adapted to be laid around a plurality of upper surfaces of conservatory walls;
- (ii) a ridge member;
- and
- (iii) a plurality of glazing bars extending between said ridge member and said ring beam;
- (iv) said ring beam comprising a channel which defines a surface for supporting the outer ends of said glazing bars;
- (v) said ridge member comprising a central member and a pair of channels disposed one to each side of said glazing bars, each said ridge channel comprising a base wall, a relatively long flange upstanding from one edge of said base wall and a relatively short flange upstanding from the opposed other edge of said base wall, and said ridge channels being mounted with their said base walls extending along a respective side face of said central member, with said long flanges of said channels lowermost;
- and
- (vi) said channels of said ridge member and of said ring beam being essentially of the same sections,
- side faces of said central member and the outwardly directed faces of said channel base walls having inter-engaging portions whereby said channels are secured to said central member.
6 more elements
A conservatory roof construction, including:
- (i) a ridge member;
- (ii) a plurality of glazing bars each extending away from and having one end supported by said ridge member;
- (iii) said one end of each glazing bar bearing on a respective support plate pivoted to said ridge member;
- and
- (iv) means for selectively setting the relative angle between said support plate and said ridge member comprising an arcuate receptor centered on a pivot axis of said support plate and having a plurality of spaced engagement means with any one of which the end of said support plate remote from a pivotal connection to said ridge member may be engaged.

A conservatory roof construction comprising:
- (i) a ring beam adapted to be laid around a plurality of upper surfaces of conservatory walls;
- (ii) a ridge member;
- (iii) a plurality of glazing bars extending between said ridge member and said ring beam, and;
- (iv) a valley member disposed between two sections of the roof lying in different planes and also extending between said ridge member and said ring beam;
- (v) said ridge member comprising a first central member and a pair of ridge channels disposed one to each side of said first central member, said ridge channels defining surfaces for supporting a plurality of ridge ends of said glazing bars and said valley member comprising a second central member;
- (vi) a pair of carriers mounted one to each side of said first central member for supporting a plurality of lower ends of said glazing bars terminating along said valley member;
- (vii) said first central member of said ridge member being of substantially the same configuration as said second central member of said valley member.

- (iii) a plurality of glazing bars extending between said ridge member and said ring-beam;
- and
- (iv) elongate valance strips;
- (v) whereby inwardly-directed faces of said ring beam and said ridge member are trimmed with said elongate valance strips, each said valance strip being of substantially the same configuration.
