Abstract

Abstract This invention discloses an improved glass pane framed by a U-shaped profile rail wherein the adhesion of the glass pane to the clamping rail is significantly increased. At least one side of the marginal area of the glass pane framed by the U-shaped profile rail is provided with a group of raised bodies which are anchored into the surface of the glass and impress themselves into a layer of elastic deformable material that lies between the glass pane and the clamping rail.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 183 words
A framed glass pane comprising: (a) a glass pane; (b) a frame press-fit on at least one marginal area of the glass pane, said frame comprising: (1) a U-shaped profile rail, and (2) an elastically resilient material disposed within the rail along the sides and bottom of the U-shaped profile for direct engagement with the marginal area of the glass pane to produce said press-fit; and (c) a plurality of raised bodies on at least one surface of the glass pane within said marginal area, each of said bodies having: (1) a height dimension sufficient to embed into the elastic resilient material when said frame is press-fit thereon to prevent relative sliding movement of the frame and glass pane in the direction of forces applied to the frame under normal operating conditions, and (2) a substantially low and regular profile above the surface of said glass pane to permit initial relative sliding movement of the glass pane relative to the elastically resilient material during press-fitting of the frame onto the marginal area of the glass pane without destructive deformation of the resilient material.
Claim 2
Dependent Claim 183 words
A framed glass pane comprising: (a) a glass pane; (b) a frame press-fit on at least one marginal area of the glass pane, said frame comprising: (1) a U-shaped profile rail, and (2) an elastically resilient material disposed within the rail along the sides and bottom of the U-shaped profile for direct engagement with the marginal area of the glass pane to produce said press-fit; and (c) a plurality of raised bodies on at least one surface of the glass pane within said marginal area, each of said bodies having: (1) a height dimension sufficient to embed into the elastic resilient material when said frame is press-fit thereon to prevent relative sliding movement of the frame and glass pane in the direction of forces applied to the frame under normal operating conditions, and (2) a substantially low and regular profile above the surface of said glass pane to permit initial relative sliding movement of the glass pane relative to the elastically resilient material during press-fitting of the frame onto the marginal area of the glass pane without destructive deformation of the resilient material.
Claim 3
Dependent Claim 39 words
A framed glass pane according to claim 1, wherein the raised bodies anchored into the surface of the glass have a width between about 0.5 mm and 2 mm and a height between about 0.2 mm and 0.5 mm.
Claim 4
Dependent Claim 18 words
A framed glass pane according to claim 2, wherein the raised bodies are striplike or punctiform in shape.
Claim 5
Dependent Claim 19 words
A framed glass pane according to claim 3, wherein the raised bodies are made of a fired-on ceramic material.
Claim 6
Dependent Claim 45 words
A framed glass pane according to claim 4, wherein said glass pane on which said frame is press-fit includes thermally treated glass; and said fired-on ceramic material is a material which has been thermally treated substantially at the same temperature as said thermally treated glass.
Claim 7
Dependent Claim 28 words
A framed glass pane according to claim 5, wherein said thermally treated glass is a bent glass which has been bent as a result of said thermal treatment.
Claim 8
Dependent Claim 28 words
A framed glass pane according to claim 5, wherein said thermally treated glass is a prestressed glass which has been prestressed as a result of said thermal treatment.
