Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A security system for the outer area of a room comprising a bullet-proof revolving door having a circular outer wall with an opening therein leading into the room and an exit, a movable door movable along said outer wall to close said opening, a release device and means for locking the movable door in combination with said releast device, said release device being a weapon detector which is positioned in the region of the revolving door outside the room, the movable door forming part of a bullet-proof surrounding of said revolving door divided by bullet-proof partition walls forming plural compartments of a first type separated by plural compartment of a second type, said compartments of said first type including an exit passage and said compartments of said second type having no exit passage, only one of said compartments of said first type being adjacent said movable door at a given time, said walls being situated outside the room, said weapon detector being disposed in an area situated in front of the movable door as seen in the revolving direction of the door.
Claim 2
Dependent Claim
182 words
A security system for the outer area of a room comprising a bullet-proof revolving door having a circular outer wall with an opening therein leading into the room and an exit, a movable door movable along said outer wall to close said opening, a release device and means for locking the movable door in combination with said releast device, said release device being a weapon detector which is positioned in the region of the revolving door outside the room, the movable door forming part of a bullet-proof surrounding of said revolving door divided by bullet-proof partition walls forming plural compartments of a first type separated by plural compartment of a second type, said compartments of said first type including an exit passage and said compartments of said second type having no exit passage, only one of said compartments of said first type being adjacent said movable door at a given time, said walls being situated outside the room, said weapon detector being disposed in an area situated in front of the movable door as seen in the revolving direction of the door.
Claim 3
Dependent Claim
36 words
In a system in accordance with claim 1, the improvement in which means are provided to block the revolving door in its revolving motion and the weapon detector cooperates with the means blocking the revolving door.
Claim 4
Dependent Claim
51 words
In a system in accordance with claim 1 the improvement in which the weapon detector includes constant magnetic field sources arranged on opposite sides of an area to be crossed to produce therein a magnetic field, induction loops and means averaging or adding the induction voltages generated to the induction loops.
Claim 5
Dependent Claim
25 words
In a system in accordance with claim 3, the improvement in which each magnetic field source is formed by ferrite magnets arranged side by side.
Claim 6
Dependent Claim
32 words
In a system in accordance with claim 4, the improvement in which the pole surfaces of the ferrite magnets of each magnetic field source define a surface curved concavely towards the area.
Claim 7
Dependent Claim
29 words
In a system in accordance with claim 3 the improvement in which the induction loops are arranged on the sides of the ferrite magnets turned away from the area.
