Abstract
Abstract A frame and sash construction for doors and windows has profiled beams of chair-shaped cross-section, the improvement being that an opening of an elongated slot in a foremost leg portion is directed upwardly towards a seat portion to receive a sealing gasket forming a packing for a window glass or mounting ledge. A backrest portion has a greater height than a rear leg portion. The seat portion is formed with a pair of ribs with opposed flanges to receive locking rods or hinge plates, and the sides of the leg portions facing each other have parallel grooves to receive ribs of the gaskets.

73 words
A frame and sash, as claimed in claim 2, wherein the diameter of the bead is not greater than the opening of the groove in order to receive between said bead and said groove a lining in the form of a hollow cylinder with a longitudinal opening corresponding to the opening of the groove and a wall thickness corresponding to the radial distance between the inner wall of the groove and the bead.
Claim 5
Dependent Claim
55 words
A frame and sash, as claimed in claim 3, wherein the foremost leg portion is detachably secured to the front face of the seat portion, and wherein there is secured to said front face a ledge of heat insulating and selectively resilient material to which said detachable foremost leg portion is secured by snap action.
Claim 6
Dependent Claim
154 words
A method for establishing a hinge connection between selectively a sash and a sash profiled beam and a frame and a frame profiled beam as claimed in claim 3, comprising the steps of: (i) cutting away, at a position near to the midportion of the profiled beam, a portion of the ledge with the bead (ii) pushing into the groove from the end thereof a cylindrical portion the length of which corresponds with the length of the cut out portion of the ledge with the bead, (iii) introducing the bead of the sash profiled beam into the opening of the circular groove so that the cylindrical portion becomes located flush with the bead (iv) moving selectively the frame and sash profile beams and the sash and frame to correct position, (v) securing the cylindrical portion (vi) pushing a hollow cylindrical lining inwards from both ends of the groove for abutment with the cylindrical portion.
