- 2. A light seal assembly according to claim 1 wherein;said window frame comprises a second side frame member and said divider panel comprises a second side panel edge; a second seal holder being attached to said second side frame member; a second sealing member having a second base portion attached to said second seal holder and a second flexible tip extending from said second base portion toward said window opening; said second flexible tip being free from engagement with said second seal holder and being made of a flexible material that is capable of bending to swing said second flexible tip relative to said second base portion from a normal position to a first deflected position; said second flexible tip engaging said second side panel edge to create a light seal there between when said divider panel is in said sealed position.
- 3. A light seal assembly according to claim 2 wherein said first and second base portions are substantially stationary and said first and second flexible tips swing about said first and second base portions respectively when moving between their respective said normal and said first deflected positions.
- 4. A light seal assembly according to claim 2 wherein said first and second seal holders comprise first and second elongated members respectively, extending along said first and second side frame members respectively.
- 5. A light seal assembly according to claim 2 and further comprisinga pair of said first sealing members attached to said first seal holder, each of said pair of said first sealing members comprising a first base portion connected to said first seal holder, and a first flexible tip extending from said first base portion into said window opening, said first flexible tips of said pair of said first sealing members forming a V-shaped configuration in cross section; a pair of said second sealing members attached to said second seal holder, each of said pair of said second sealing members comprising a second base portion connected to said second seal holder and a second flexible tip extending from said base portion into said window opening, said second flexible tips of said pair of said second sealing members forming a V-shaped configuration in cross section.
- 6. A light seal assembly according to claim 5 wherein said first side panel edge of said divider panel engages both of said first flexible tips of said pair of said first sealing members when in said first sealed position, and said second side panel edge of said divider panel engages both of said second flexible tips of said pair of said second sealing members when in said first sealed position.
- 7. A sealed laser system comprising:a work station and a load station positioned in spaced relation to one another; a laser tool located at said work station; a window frame between said work station and said load station and having a plurality of frame members forming a window opening, said frame members including a first side frame member and a second side frame member; first and second sealing members, each having a base portion and a flexible tip, said base portions of said first and second sealing members being attached to said first and second side frame members, respectively; said flexible tips of said first and second sealing members extending from said base portions into said window opening, and being flexible to bend and swing about said base portions from a normal position to a deflected position; a divider panel having first and second panel side edges; a pedestal supporting said divider panel within said window opening for rotation about a table axis from a first sealed position wherein said first and second side panel edges engage and bend said tips of said first and second sealing members respectively from their respective normal positions to their respective deflected positions; said first sealing member forming a light seal between said first side panel edge of said first divider panel and said first side frame member of said window frame when said divider panel is in said first sealed position; said second side frame member forming a light seal between said second side panel edge of said divider panel and said second side frame member of said window frame when said divider panel is in said first sealed position.
- 8. A sealed laser system according to claim 7 wherein said divider panel is positioned on a work table surface and divides said work table surface into first and second work piece surfaces.
- 9. A sealed laser system according to claim 7 wherein each of said flexible tips of said first and second sealing members are movable to swing away from said first deflected position back to said normal position and then to a second deflected position; said pedestal being pivotal to move said divider panel to a second sealed position wherein said second side panel edge engages and moves said flexible tip of said first sealing member to its respective second deflected position and said first side panel edge engages and moves said flexible tip of said second sealing member to its respective second deflected position.
- 10. A light seal assembly comprising:a window frame forming a window opening and comprising at least a first side frame member positioned adjacent said window opening; a sealing member comprising in cross section a base portion attached to said first side frame member and a flexible tip extending from said base portion toward said window opening; said flexible tip of said sealing member being comprised of a flexible material capable of bending to swing said flexible tip in one direction relative to said base portion from a normal position to a first deflected position, said flexible tip being capable of bending relative to said base portion in another direction from said normal position to a second deflected position different from said first deflected position; a divider panel having a first panel edge and an opposite second panel edge and being mounted within said window frame for rotation from a first sealed position wherein said first panel edge engages said flexible tip and moves said flexible tip to said first deflected position, to a second sealed position wherein said second panel edge engages said flexible tip and moves said flexible tip to said second deflected position; said sealing member providing a light seal between said side frame member and said divider panel when said divider panel is in either of said first or said second sealed positions.
- 11. A light seal assembly comprising:a window frame forming a window opening and comprising at least a first side frame member positioned adjacent said window opening; a first pair of sealing members each comprising in cross section a base portion attached to said first side frame member and a flexible tip extending from said base portion toward said window opening, said flexible tips of said first pair of sealing members forming a V-shaped configuration with one another; said flexible tips of said pair of sealing members being comprised of a flexible material capable of bending to swing said flexible tips in one direction relative to said base portion from a normal position to a first deflected position, said flexible tips being capable of bending relative to said base portion in another direction from said normal position to a second deflected position different from said first deflected position; a divider panel having a first panel edge and an opposite second panel edge and being mounted within said window frame for rotation from a first sealed position wherein said first panel edge engages said flexible tips of said pair of seal members and moves said flexible tips to said first deflected position; said divider panel being capable of rotating to a second sealed position wherein said second panel edge engages said flexible tips of said pair of seal members and moves said flexible tips to said second deflected position; said pair of sealing members providing a light seal between said side frame member and said divider panel when said divider panel is in either of said first or said second sealed positions.
