Method of manufacturing a connecting element

Claim 1

A method of manufacturing a connecting element, particularly for window and door frames, facade walls and the like, comprising the steps of providing two elongated profiled members 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 provided with at least two separating members which are connected with said elongated profiled members and spaced from one another in a second direction transverse to said first direction and to the direction of elongation, so that said separating members subdivide said channel into an intermediate hollow space formed between said separating members, and two sections spaced from one another in said second direction and each located outside of a respective one of said separating members and outwardly opening as considered in said second direction, whereby each of said separating members forms a bottom wall of a respective one of said sections of said channel and separates the same from said intermediate hollow space, said elongated profiled members together with said bottom walls of said sections of said channel forming a unitary profiled element; supplying into said sections of said channel a hardenable heat insulating material so as to fill said sections of said channel; and hardening said material in the latter so as to form in said sections two heat insulating inserts connecting said elongated profiled members with each other, spaced from one another by said intermediate hollow space, and separated from the latter by said bottom walls; inserting into said intermediate hollow space a tool; and separating by said tool said bottom walls of said inserts from the remainder portions of said profiled members so as to remove said bottom walls from said intermediate hollow space, whereupon said profiled members remain connected with one another only by said two heat insulating inserts spaced from one another by said intermediate hollow space.

Claim 2

A method of manufacturing a connecting element, particularly for window and door frames, facade walls and the like, comprising the steps of providing two elongated profiled members 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 provided with at least two separating members which are connected with said elongated profiled members and spaced from one another in a second direction transverse to said first direction and to the direction of elongation, so that said separating members subdivide said channel into an intermediate hollow space formed between said separating members, and two sections spaced from one another in said second direction and each located outside of a respective one of said separating members and outwardly opening as considered in said second direction, whereby each of said separating members forms a bottom wall of a respective one of said sections of said channel and separates the same from said intermediate hollow space, said elongated profiled members together with said bottom walls of said sections of said channel forming a unitary profiled element; supplying into said sections of said channel a hardenable heat insulating material so as to fill said sections of said channel; and hardening said material in the latter so as to form in said sections two heat insulating inserts connecting said elongated profiled members with each other, spaced from one another by said intermediate hollow space, and separated from the latter by said bottom walls; inserting into said intermediate hollow space a tool; and separating by said tool said bottom walls of said inserts from the remainder portions of said profiled members so as to remove said bottom walls from said intermediate hollow space, whereupon said profiled members remain connected with one another only by said two heat insulating inserts spaced from one another by said intermediate hollow space.
