Abstract

Abstract The method of the present invention is performed by providing a glass sheet having first and second opposite surfaces merging with each other along a peripheral ground angled surface setting-off with the glass sheet first surface an included angle substantially greater than normal. The glass sheet is placed in a mold having opposing cavity portions which collectively define a cavity including a peripheral edge cavity portion defined in part by a cavity defining surface which lies in the plane of the glass sheet first surface when the mold is closed. The mold is then closed such that the cavity defining surface and the glass sheet round angled surface set-off and angled complementary to the included angle and with the glass sheet per surface abutting the cavity defining surface inboard of the glass sheet ground angled surface. Polymeric/copolymeric synthetic plastic material is injected into the peripheral cavity portion to completely encapsulate the glass sheet periphery with a border, frame or encapsulation having a first exterior surface coplanar with the glass sheet first surface whereby the latter two surfaces are “flush-to-front” and the glass sheet periphery is in undercut interlocked relationship with the injection molded border.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 205 words
A method of forming a unitized article which includes a border along a periphery of a glass sheet comprising the steps of: (a) providing a glass sheet having first and second opposite surfaces merging with each other along a peripheral surface which includes an angled surface setting-off with the glass sheet first surface an included angle substantially greater than normal, (b) placing the glass sheet in a mold having opposing cavity portions which collectively define a cavity including a peripheral edge cavity portion defined in part by a cavity defining surface which lies in the plane of the glass sheet first surface when the mold is closed, (c) closing the mold such that the cavity defining surface and the glass sheet angled surface set-off an angle complementary to said included angle and with the glass sheet first surface abutting the cavity defining surface inboard of the angled surface, and (d) injecting hot synthetic plastic material into the peripheral cavity portion to completely encapsulate the glass sheet periphery by a synthetic plastic material border having a first exterior surface coplanar with the glass sheet first surface whereby the latter two surfaces are flush and the glass sheet periphery is in undercut interlocked relationship with the border.
Claim 2
Independent Claim 205 words
A method of forming a unitized article which includes a border along a periphery of a glass sheet comprising the steps of: (a) providing a glass sheet having first and second opposite surfaces merging with each other along a peripheral surface which includes an angled surface setting-off with the glass sheet first surface an included angle substantially greater than normal, (b) placing the glass sheet in a mold having opposing cavity portions which collectively define a cavity including a peripheral edge cavity portion defined in part by a cavity defining surface which lies in the plane of the glass sheet first surface when the mold is closed, (c) closing the mold such that the cavity defining surface and the glass sheet angled surface set-off an angle complementary to said included angle and with the glass sheet first surface abutting the cavity defining surface inboard of the angled surface, and (d) injecting hot synthetic plastic material into the peripheral cavity portion to completely encapsulate the glass sheet periphery by a synthetic plastic material border having a first exterior surface coplanar with the glass sheet first surface whereby the latter two surfaces are flush and the glass sheet periphery is in undercut interlocked relationship with the border.
Claim 3
Dependent Claim 25 words
The method as defined in claim 1 wherein the border has a second exterior surface non-coplanar to and spaced from the glass shelf second surface.
Claim 4
Dependent Claim 14 words
The method as defined in claim 1 wherein the included angle is substantially 135°.
Claim 5
Dependent Claim 21 words
The method as defined in claim 1 including the step of grinding the peripheral surface to form the angled surface thereof.
Claim 6
Dependent Claim 24 words
The method as defined in claim 1 wherein the angled surface and the glass sheet second surface merge at a peripheral terminal edge surface.
Claim 7
Dependent Claim 30 words
The method as defined in claim 1 wherein the angled surface and the glass sheet second surface merge at a peripheral terminal edge surface ranging between 0.005 to 0.02 inch.
Claim 8

Claim 9
Dependent Claim 18 words
The method as defined in claim 1 wherein the unitized article is a flush-to-front wall of a drawer.
Claim 10
Dependent Claim 48 words
The method as defined in claim 1 wherein the mold includes at least two mold bodies having opposing contacting surfaces in the closed position of the mold defining a parting line plane of the mold, and the parting line plane is coplanar to the glass sheet second surface.
Claim 11
Dependent Claim 25 words
The method as defined in claim 9 wherein the border has a second exterior surface non-coplanar to and spaced from the glass shelf second surface.
