Abstract

SUMMARY OF THE INVENTION The object of the invention is to improve the glazing of wooden windows using the inventive bar without fastening it with nails or screws. This purpose is achieved by the use of a rigid bar which, with its slanted protrusion, not fits into the inclined groove formed in the rebate for the glass and is thus secured against pressures that perpendicular to the acla surface. Intermediate glass is made with an elastic bar.

Description

(54) Rigid glazing bead for wooden windows

The object of the invention is to improve the glazing of wooden windows using the batten according to the invention, without fixing it with nails or screws.

This is achieved by the use of a rigid bar which, with its sloping projection on the horizontal bottom surface, fits into an oblique groove formed in the rebate for the glass and is thereby secured against pressures acting perpendicular to the acla surface. Finishing glass is made of elastic strip.

The invention relates to glazing bars for fixing glass in wood windows and using screws or nails.

The prior art glazing bars for wood windows are either made of elastic materials (e.g. neoprene), pressed both under the glass and into the groove, and / or from rigid materials such as high-resilient PVC or aluminum, and fasten nails or screws.

Fixed glass against external pressures during wind gusts and the like. requires that, in the case of elastic glazing bars, the profile be inserted both under the glass and into the groove in order to withstand forces perpendicular to the glass surface.

To insert the profile under the glass space must be created around the perimeter of the glass, ie the glass must be cut with sufficient clearance around the perimeter. However, this creates a permanent deformation of the sash during loading, and therefore, in some flexible glazing bars, the glass must be supported by a wooden base in the corners.

For rigid glazing profiles made of PVC materials, which must be fastened to nails or screws in glass semipodding at elevated temperature, especially in summer, warping of the lath between the nails or screws, if the bars are not leaking.

The rigid bar requires under-sealing at the points of contact with the glass, but when the hard bar is pressed onto the glass, the sealant is displaced and loses its function.

The above-mentioned drawbacks in fixing glass to wooden windows are overcome by the glazing strip according to the invention, which is based on the fact that the rigid material strip has a projection on the lower horizontal surface which ensures self-resistance of the strip without nails or screws.

Self-resistance is achieved in that the resultant of forces acting on the glass surface pushes the lower surface of the bar into the wing rebate. The molding does not touch the glass and allows for its elastic molding.

The oblique protrusion on the lower horizontal surface of the rigid material bar creates the conditions for reliably securing the bar against warping along the entire profile, without fastening with nails or screws. The sheet of rigid material is inserted into the groove in the semi-groove for the glass without the necessary deformations and forms the carrier of the sealing elastic strip.

The accompanying drawing shows an example of an embodiment of a glazing strip according to the invention and its placement in a semi-rail for glass in a wood window.

The rigid strip 1 has on its horizontal lower surface 4 an oblique projection 4 which, when assembled, fits into a groove 4 formed in the half-groove 2 for the glass 2 of the wooden window frieze. On its horizontal upper surface 2, the upper oblique projection 2 is at its gripping and the upper surface 2 has an obtuse angle.

The inclined projections 2, 6 have the same slope. The upper protrusion 2 passes at the top into a horizontal rim g which is spaced from the surface of the glass 2 so that the lower oblique protrusion 4 can be slid into the oblique grip 5 without distorting the entire profile of the bar 6. The glass 2 is sealed by an elastic profile 11.
