Holding rail for holding glass profile elements

A device for retaining a glass fenestration comprising individual glass longitudinal U-section components in form of insulating, glass elements;

• at least one retaining rail for lateral guidance and support of said individual longitudinal glass components;
• said retaining rail having a metal retaining section for retaining at least one face-side area of the glass fenestration;
• two projecting metal flange sections for lateral guidance of at least one component of the glass fenestration;
• said flange sections and said retaining section being fastened together by a thermally insulating connecting fixture;
• a plurality of said glass longitudinal U-section components being arranged in parallel adjacent to each other with ends of said components supported by said retaining rail in a channel of said retaining rail, said channel being formed by the two flange sections on each outer side, said channel having an inner part between said flanges and connecting elements formed from thermally insulating material, said inner part being insulated from said flange sections and supporting said glass elements, said thermally insulating material preventing condensation of water within a hollow space between two opposing glass elements;
• said at least one retaining rail being vertical and securing glass structural-section component holders retaining said glass U-section components;
• said retaining section having screw fastening means for securing a metal structural section securing section and said metal flange section, said flange section and said securing section being fastened together by a heat-insulating or thermally separating connecting fixture;
• said connecting fixture having at least two mutually adjacent connecting webs of poorly heat-conducting material based on plastics paralleling said retaining rail, said connecting fixture and a double web being of polyamide and are coated, said flange section and said retaining section comprising a length of aluminum structural section, said retaining section having a substantially rectangular cross-section with outer supporting components, said two flange sections providing lateral guidance of said glass U-section components, said retaining rail having a U-shaped cross-section enclosing face-side areas of the fenestration, said two flange sections comprising sides of said U-shape, said U-shape having a base comprising said retaining and securing sections connected on both sides to said flange sections by said connecting fixture, a connection between said connecting fixture and a metal section and a flange section being established by a shaped head of one component accommodated in a C-sectional accommodating groove and engaging a back of a hooked edge of said accommodating groove;
• connecting means having webs with substantially T-sectional terminating sections for engaging said back of said C-sectional accommodating groove, said glass structural-section component holders retaining terminal areas of said glass structural-section components and being tensionable at any desired height to a C-sectional securing section and thereby being secured by threaded screw means, said retaining rail having a width adjusted to the glass fenestration being retained, said retaining rail being U-shaped for horizontal installation with a retaining area in form of a length of rectangular structural section adjacent to face sides of the glass fenestration and fastened to a reinforced short web of L-sectional flange sections on both sides of a lateral support, said retaining rail being installed horizontally and having at least one flange section on a lower surface.
