BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a sectional structure as defined in the preamble to claim 1.
BACKGROUND OF THE INVENTION
In prior art are known, e.g. through the references GB 2202260, EP 0 095 820, DE 26 48 175, sectional structures comprising a glazier's strip section having a first side brace flange for bracing one side of the glass pane, and a casing section comprising a second side brace flange for bracing the other side of the pane, and a bottom rest which is substantially perpendicular against the second side brace flange, the pane being held in the gap defined by the first and second side brace flanges and against the bottom rest when the sections have been attached to each other. For attachment, interlockable fixing 1 have been formed on the glazier's strip section and on the casing section which serve the detachable attachment of the glazier's strip section to the casing section. The fixing members comprise a first locking claw formed on the casing section, and a second locking claw, formed on the glazier's strip section to interlock with the first locking claw. The locking claws interlock with each other by a so-called snap joint.
The problem with these sectional structures of prior art is that the glazier's strip section cannot be attached to the casing section so that the first side brace flange of the glazier's strip section abutting on the surface of the pane would not slip in the direction of the pane surface when the glazier's strip section is being attached to the casing section. Slipping of the surfaces in relation to each other is particularly objectionable when the pane is fixed by cementing, when between them is interposed a layer of cement, which tends to become packed, between the surfaces in the direction of slip, causing the cement layer to become non-uniform.
An additional problem presented by the structure of reference GB 2202260 is that the glazier's strip section is not held firmly attached to the casing section without the pane between the side brace flanges, without a packing urged against the pane and without a flange provided on the glazier's strip section and urged against the surface of the window frame. In addition to the members just mentioned, the window frame is also required to hold the sections together. This implies that the sections cannot separately by themselves be connected with each other for cutting them off to desired length or for mitre cutting so that they would be held firmly together.
SUMMARY OF THE INVENTION
The object of the invention is to eliminate the drawbacks mentioned.
The device of the invention is characterized by that which is stated in claim 1.
As taught by the invention, the structure comprises a first brace member, formed on the casing section, and a second brace member, formed on the glazier's strip section for entering the first brace member so as to constitute a pivot between the sections in such manner that with the first and second brace members braced against each other the glazier's strip section can be turned about the pivot constituted by the first and second brace members in cooperation so as to press the first side brace flange against the surface of the pane in substantially perpendicular direction into a locked position, whereby the first and second lock claws become interlocked.
The invention affords the advantage that the glazier's strip section can be attached to the casing section so that the first side brace flange is urged in substantially perpendicular direction against the surface of the pane. Hereby the side brace flange will not come into sliding contact with the pane. There will thus be no displacement, or packing in any direction, of the cement layer e.g. on the side brace flange, and the cement layer will remain uniform. The glazier's strip section can be installed using a press which operates mechanically, e.g. pneumnatically or hydraulically. The glazing arrangement renders possible, in particular, easy attachment of the panes to the sections by cementing, implying that the panes nee
