Abstract:
1. A frame assembly for a touch screen, comprising: a plurality of linear covering plates; a plurality of linear edge members, each edge member having a C-shaped cross section with an end-to-end linear opening along an inner side of each edge member for receiving an edge of said touch screen, said inner side of each edge member having a top half and a bottom half that close in towards each other from above and beneath said opening of each edge member, wherein, on a bottom surface of said top half and on a top surface of said bottom half of said inner side of each edge member, there are matching linear vertical troughs, respectively, for holding a covering plate sealing said opening of each edge member; a plurality of L-shaped corner members connecting said edge members end-to-end into a rectangular frame surrounding said touch screen, each corner member having a C-shaped cross section and an L-shaped opening along an inner side of each corner member for receiving a corner of said touch screen, said inner side of each corner member having a top half and a bottom half that close in towards each other from above and beneath said opening of each corner member, wherein, on a bottom surface of said top half and on a top surface of said bottom half of said inner side of each corner member, there are matching L-shaped vertical troughs, respectively, for holding covering plates extended from adjacent edge members; and a plurality of flat connection pieces, each connection piece patching a corner member and at least an edge member together; A frame assembly for a touch screen, comprising: a plurality of linear covering plates; a plurality of linear edge members, each edge member having a C-shaped cross section with an end-to-end linear opening along an inner side of each edge member for receiving an edge of said touch screen, said inner side of each edge member having a top half and a bottom half that close in towards each other from above and beneath said opening of each edge member, wherein, on a bottom surface of said top half and on a top surface of said bottom half of said inner side of each edge member, there are matching linear vertical troughs, respectively, for holding a covering plate sealing said opening of each edge member; a plurality of L-shaped corner members connecting said edge members end-to-end into a rectangular frame surrounding said touch screen, each corner member having a C-shaped cross section and an L-shaped opening along an inner side of each corner member for receiving a corner of said touch screen, said inner side of each corner member having a top half and a bottom half that close in towards each other from above and beneath said opening of each corner member, wherein, on a bottom surface of said top half and on a top surface of said bottom half of said inner side of each corner member, there are matching L-shaped vertical troughs, respectively, for holding covering plates extended from adjacent edge members; and a plurality of flat connection pieces, each connection piece patching a corner member and at least an edge member together, wherein, on an inner surface of said top half of said inner side of each corner member, there is an L-shaped lateral trough; there is another matching L-shaped lateral trough along an inner surface of an outer side of each corner member; said two lateral troughs are for holding a circuit board inside each corner member; on an inner surface of said top half of said inner side of each edge member, there is a linear lateral trough; there is another matching linear lateral trough along an inner surface of an outer side of each corner member; said two lateral troughs are for holding a circuit board inside each edge member.
