Anti-robbery and anti-hostage equipment provided with a one-way rotating door for banks and the like
First Claim
1. Anti-robbery and anti-hostage equipment, for the premises of banks and the like, comprising, in combination, means forming at least one laterally confined passage, having a ceiling and a floor, communicating with the premises to be protected;
- at least one rotating door, including a vertically oriented rotatable post and a plurality of angularly spaced elements secured to and extending radially from said post, in each passage freely rotatable in a single direction to permit one person at a time to pass along said passage in said single direction; and
means operable, responsive to a person entering into said door and attempting to rotate said door, to pass along the passage in a direction opposite to said single direction, to lock said door against rotation;
said angular spaced radial elements comprising radially extending imperforate walls, having a height substantially equal to the height of said at least one laterally confined passage;
said column and said radially extending walls having vertically elongated bulge portions projecting into the sector spaces defined between adjacent angularly spaced radially extending walls;
said bulges being positioned on both surfaces of each radially extending wall;
said bulges extending vertically only intermediate the height of a person to provide full clearances, in the sector spaces above and below said bulges, to provide full clearance for the head and feet of such person;
whereby only one person at a time can occupy a sector space.

Abstract
The premises to be protected have at least one laterally confined passage communicating therewith, such as an entrance passage, an exit passage, or both. Each passage has mounted therein at least one rotating door, of the type including a vertically oriented rotatable post and a plurality of angularly spaced elements secured to and extending radially from the post, the door being freely rotatable in a single direction to permit one person at a time to pass along the passage in the single direction. Approximately half the circumferential extent of each door is enclosed by a semi-cylindrical barrier, and a treadle or other type of depressible floor section, responsive to the weight of a person entering into the door and attempting to rotate the door in the direction opposite to such single direction, operates a locking means device preventing movement of the door in either direction so that such a person is trapped in the door or between two doors located serially along the passage. The treadle or the like may be biased to a position flush with the floor by a positive air pressure so that, if the air pressure line is severed, the treadle will automatically drop and lock the door against rotation. Safety enclosures may be associated with the rotatable doors to allow a hostage to move safely out of any line of fire along the passage. The passage may be designed with portions extending at angles to each other, or even in reverse direction, so that there is no clear line of fire along the passage. The angularly spaced elements may be formed with bulges, as may also the post, assuring that only one person can enter the door between adjacent angularly spaced elements at a time.
