Abstract

A connecting element, particularly for windows, doors and the like, has two elongated profiled elements spaced from one another in a first direction transverse to the direction of elongation thereof so as to bound with one another a channel, and two heat insulating inserts located in the channel, which inserts extend in the first direction between the profiled elements and are spaced from one another in a second direction transverse to the first direction so as to provide an intermediate hollow space between the inserts. A method of manufacturing the connecting element includes the steps of providing the two elongated profiled elements which bound with one another the channel, supplying into the channel a hardenable heat insulating material so as to fill two sections of the channel which are spaced from one another whereby an intermediate hollow space is provided between the sections, and hardening the heat insulating material in these sections of the channel, so that the hardened material forms the above-mentioned two heat insulating inserts which are connected with the profiled elements and spaced from one another.

Dependent claims

A method of manufacturing a connecting element, particularly for windows, door and the like, comprising the steps of providing two elongated profiled elements;

positioning said elongated profiled elements so that they are laterally spaced from one another and bound with one another an elongated channel having an upper section and a lower section which are spaced from each other in an upright direction;
supplying a hardenable heat insulating material into at least a portion of the length of said lower section of said channel;
thereafter inserting a transverse member extending over at least said portion between said elongated profiled elements only at a lowermost location of said upper section and at a distance from said lower section so as to bound a hollow intermediate space therebetween and to separate said upper section from said intermediate space, and fixing said transverse member to said elongated profiled elements;
supplying the hardenable heat insulating material into the thus-separated upper section of said channel so as to fill said upper section;
and hardening the hardenable heat insulating material in said upper and lower sections of said channel so as to form two heat insulating inserts which connect said elongated profiled elements with each other and are spaced from one another in the upright direction by said intermediate space.
