System for preventing crime in high traffic areas and sites using low voltage power
First Claim
1. A substantially automatic, compact, robotic-like, security system for preventing crime in high traffic buildings comprising:
- at least one revolving door unit;
a geared flywheel fixed to said revolving door unit, wherein the geared flywheel in operation restricts rotation of the revolving door unit in an anti-clockwise direction only;
a semi-circular inside wall, wherein the at least one revolving door unit includes two pairs of door panels that revolve within the semi-circular wall, and the two pairs of door panels define at least four zones;
said at least four zones including, in operation, at least two zones defining independent isolated chambers, wherein each independent isolated chamber is formed by two door panels and said inside semi-circular wall;
four equidistant plunger accepting cylinders attached to said geared flywheel;
one plunger attached to a fixed section of said semi-circular wall;
wherein a respective timing apprehension position of the revolving door unit is defined each time a respective plunger accepting cylinder is located opposite a plunger;
a low voltage electromechanical subsystem including at least two personnel detectors, below said revolving doors, which are activated by personnel stepping over them; and
at least two other detectors positioned to scan within said independent isolated chambers; and
a substantially automatic means for electromechanically stopping said revolving door, without alerting person within revolving door, only when (i) a timing apprehension position of said revolving door unit is achieved and (ii) a signal is received from one or more of said detectors, for thwarting an illegal activity, which when stopped forms said independent isolated chambers from which access/exchange with an open chamber is not achievable.

Abstract
A substantially automatic, robotic-like system to aid in preventing crime in high trafficked buildings and other public sites, using only low voltage power, is described. In various modes it can protect public buildings such as schools, stadiums, open air markets, banks, office buildings from entrance of persons carrying weapons or separately trying to pass weapons into a protected area, even in the event of general power loss. Here a well designed, compact solution is provided for weapons detection and the detainment of persons attempting to disrupt, destroy or harm citizens in public buildings such as schools, banks, etc. with a minimum of restriction of access by persons regularly using the facilities. In other variations, it can be used to prevent unauthorized removal of costly or dangerous items from protected buildings or areas. Here a substantially automatic method is similarly provided for detection and detention of persons attempting to illegally remove items either without paying or that are not for sale in a store setting.
