Hinged case providing sectional cover with anti-pinch interleaving through

A case providing a sectional cover for a substantially flat object adapted to be retained within the sectional cover, said case comprising:

• a front cover having a first flat inner surface;
• a back cover having a second flat inner surface;
• said front and back covers having respective marginal edges arranged in juxtaposed relation to each other;
• hinge means having a longitudinal axis and pivotably connecting said front and back covers along said juxtaposed marginal edges thereof to provide for pivoting movement of said front and back covers about said longitudinal axis relative to each other between open and closed positions of said case;
• a first elongated member along said marginal edge of said front cover proximally related to said back cover and forming a part of said front cover, said first elongated member being arcuately curved along its extent to define a first longitudinally extending trough;
• a second elongated member along said marginal edge of said back cover proximally related to said front cover and forming a part of said back cover, said second elongated member being arcuately curved along its extent to define a second longitudinally extending trough;
• said first and second flat inner surfaces of said front and back covers facing each other with said first and second elongated members having the respective first and second troughs thereof disposed in facing relationship to define a substantially cylindrical cavity between said first and second elongated members in the closed position of the case;
• one of said first and second elongated members being slidably received within the trough of the other elongated member in overlapping interleaved relationship with respect thereto in response to relative pivoting movement of said front and back covers about said longitudinal axis of said hinge means from the closed position of the case to the open position thereof;
• and
• said one elongated member and the other elongated member being disposed in nested relationship with said first and second flat inner surfaces of said front and back covers lying in substantially coplanar relationship when the case is in its open position.

A case providing a sectional cover for a substantially flat object adapted to be retained within the sectional cover, said case comprising:

• a front cover having a first flat inner surface;
• a back cover having a second flat inner surface;
• said front and back covers having respective marginal edges arranged in juxtaposed relation to each other;
• first and second hinge means having a common longitudinal axis and pivotably connecting said front and back covers along said juxtaposed marginal edges thereof to provide for pivoting movement of said front and back covers about said longitudinal axis relative to each other between open and closed positions of said case;
• said first and second hinge means being respectively spaced from each other and located at the opposite ends of the juxtaposed marginal edges of said front and back covers;
• a first elongated member along said marginal edge of said back cover proximally related to said front cover and forming a part of said back cover, said second elongated member being disposed in the space between said first and second hinge means and being arcuately curved along its extent to define a second trough;
• a second elongated member along said marginal edge of said back cover proximally related to said front cover and forming a part of said back cover, said second elongated member being disposed in the space between said first and second hinge means and being arcuately curved along its extent to define a second trough;
• said first and second flat inner surfaces of said front and back covers facing each other with said first and second elongated members having the respective first and second troughs thereof disposed in facing relationship to define a substantially cylindrical cavity between said first and second elongated members and extending in the space between said first and second hinge means in the closed position of the case;
• one of said first and second elongated members being slidably received within the trough of the other elongated member in overlapped interleaved relationship with respect thereto in response to relative pivoting movement of said front and back covers about said longitudinal axis of said first and second hinge means from the closed position of the case to the open position thereof;
• and
• said one elongated member and the other elongated member being disposed in nested relationship with said first and second flat inner surfaces of said front and back covers lying in substantially coplanar relationship when the case is in its open position.
