Abstract
The present invention concerns a revolving door device having arcuate screens arranged on diametrically opposite sides of the passage space constituting part of the revolving door closely adapted to the fixed outer walls of the device. Said screens being connected with each other through a partition wall divided up in three sections having the central section openable. The respective outer sections is aligned along a chord of the circular space so that when said screens are in a position for access to the respective passage spaces, a free through path may be obtained from entrance opening to the outer through the openable central section in case of emergency.
Claims25
A revolving door comprising two spaced cylindrical wall sections disposed to at least partially enclose a generally cylindrical passage space having two diametrically opposed passage openings, revolving door means rotatable within said cylindrical passage space, said revolving door means comprising structure support means diametrically disposed on opposite sides of the center of said cylindrical passage space, said revolving door means further comprising door elements pivotably mounted on said structure support means for pivotal movement between open and closed positions about axes spaced from the center of said cylindrical passage space, and turntable means for rotatably supporting said revolving door means for rotary movement within said cylindrical passage space between open and closed positions, said turntable means comprising cylindrical support guide means spaced from the center of said cylindrical passage space and generally overlying the circular path of travel of said structure support means, said cylindrical support guide means rotatably engaging said structure support means to thereby rotatably support said revolving door means, said structure support means having outer panel sections which close off said passage openings when said revolving door is rotated to said closed position, said spaced cylindrical wall sections each having a pivotal door unit to provide egress from said cylindrical passage space when said revolving door is in said closed position.
A revolving door according to claim 14, wherein said outer panel sections have a partial generally cylindrical configuration, said structure support means further comprising an arcuate panel section extending from said outer panel section and a third panel section extending between said outer panel section and said arcuate panel section such that said structure support means is generally hollow, said third panel being a substantially planar panel and being substantially parallel to said center line of said through passage when said revolving door means is in said open position.
A revolving door comprising two spaced cylindrical wall sections disposed to at least partially enclosed a generally cylindrical passage space having two diametrically opposed passage openings, revolving door means rotatable within said cylindrical passage space, said revolving door means comprising structure support means diametrically disposed on opposite sides of the center of said cylindrical passage space, said revolving door means further comprising door elements pivotably mounted on said structure support means for pivotal movement between open and closed positions about axes spaced from the center of said cylindrical passage space, and turntable means for rotatably supporting said revolving door means for rotary movement within said cylindrical passage space between open and closed positions, said passage openings being unblocked by said structure support means when said revolving door means is in said open position, said diametrically opposed passage openings defining a generally linear through passage extending through said cylindrical passage space when said revolving door means and said door elements are in said open position, said through passage having a center line passing through the center of said cylindrical passage space, said door elements in said closed position having their inner radial edges thereof disposed adjacent to one another substantially at the center of said cylindrical passage space, said revolving door means being constructed such that when said revolving door means is in said open position and said door elements are in said closed position, said door elements are disposed in a general plane which is disposed at an acute angle relative to said center line of said through passage.
A revolving door comprising two spaced cylindrical wall sections disposed to at least partially enclosed a generally cylindrical passage space having two diametrically opposed passage openings, revolving door means rotatable within said cylindrical passage space, said revolving door means comprising structure support means diametrically disposed on opposite sides of the center of said cylindrical passage space, said revolving door means further comprising door elements pivotably mounted on said structure support means for pivotal movement between open and closed positions about axes spaced from the center of said cylindrical passage space, and turntable means for rotatably supporting said revolving door means for rotary movement within said cylindrical passage space between open and closed positions, said passage openings being unblocked by said structure support means when said revolving door means is in said open position, said diametrically opposed passage openings defining a generally linear through passage extending through said cylindrical passage space when said revolving door means and said door elements are in said open position, said through passage having a center line passing through the center of said cylindrical passage space, said door elements in said closed position having their inner radial edges thereof disposed adjacent to one another substantially at the center of said cylindrical passage space, said cylindrical passage space being divided into two accessible portions when said revolving door means is in said open position and said door elements are in said closed position, one of said accessible portions opening up to one of said passage openings and being defined by said door elements, a part of each of said structure support means and a part of one of said cylindrical wall sections, the other of said accessible portions opening up to the other of said passage openings and being defined by said door elements, a part of each of said structure support means and a part of the other of said cylindrical wall sections, each of said two accessible portions extending on opposite sides of a diametrical line which is perpendicular to said center line of said through passage.
