Definitions

• the present invention relates to an automatic admittance control servosystem with interlocked doors, the outer door being provided with a metal detector.
• the guardian has to check that after an alarm an ill- intentioned person coming in the box, for example in the space between said two interlocked doors after the metal detector, does not leave any weapon within said space that can be picked up by the same person or by his accomplices after the next transit through the metal detector, this time without alarm, thus baffling the vigilance.
• the admittance system as claimed consists of a transit box, with at least two doors, which is coupled to a metal detector and is provided with means for sweeping the space between the two doors in order to automatically check the presence of weapons therein.
• the weapons could be laid down by an ill-intentioned person in order to commit a robbery later on when the gangster or his accomplices crossing the metal detector again, this time without weapons, have free admittance.
• Fig. 1 is an elevational front view of a box which is part of an admittance system according to a first embodiment of the invention, the doors of the box being locked;
• Fig. 2 is a section along the line A-A of Fig. 1;
• Fig. 3 is a top plan view of an oleodynamic actuator and the driving means of the admittance system according to the first embodiment of the invention
• Figs. 4a to 4e are schematic top plan views showing the operation of the admittance system of the preceding figures in case of a transit without alarm;
• Figs. 5a to 5e are views like those of Figs. 4a to 4e but in case of a transit with alarm;
• Figs. 6a to 6f are views like those of Figs. 5a to 5e but relative to a second embodiment of the invention; and Figs. 7a to 7e are views like those of Figs. 5a to 5e, but concerning the operation of a third embodiment of the invention.
• a transit box generally indicated as 1, and constructed with standard section and sheet preferably of stainless steel and having the form of a parallelepiped is depicted.
• a transit box generally indicated as 1
• standard section and sheet preferably of stainless steel and having the form of a parallelepiped
• two opposite walls are missing.
• Both doors are hinged on vertical, parallel axis which are close to each other and are placed near the inner corner of the shorter wall 3 of the box.
• the free ends of the doors revolve skimming over the opposite wall 4 of the box along a central arc of the whole angular elongation of 180°.
• a metal detector 6 is provided near the entrance 5.
• a casing 7 comprising a pair of oleodynamic actuators 8A and 8B, an electropump 9 and an oil reservoir 10 supported by suitable fittings.
• Each oleodynamic actuator is mounted so as to rotate on a support 11A and 11B, respectively, and is provided with oil feeding hoses.
• the piston rod of each oleodynamic actuator 8A and 8B is linked at its free end with a lever 12A and 12B, respectively, to rotate the doors.
• the operation of the actuators is controlled by means of electrovalves of an electronic system (not shown). Under the control of the latter the doors can rotate from a closed position to the locked position, in which they are placed side by side (Figs. 1 and 2).
• the locking device of the door 2B opens and the man pushing the door can be admitted to the protected room.
• the door 2B returns automatically to the closed position (Fig. 4e).
• the man entering the controlled space of the box has something that causes the alarm signal to be activated by the metal detector and therefore the door 2A does not close and the door 2B does not open (Fig. 5b).
• the man receives the instruction of going out and laying down the metal thing that does not allow him to go across the door (Fig. 5c).
• the door 2A then closes and the electronic system provides a control signal to the actuators which rotate the doors 2A and 2B to each other to the extent in which they are parallel and touch each other (Fig.
• a recorded instruction invites the person entered the space between the doors to go out (Fig. 6c).
• the entrance door closes (Fig. 6d) and afterwards the two doors, that in this embodiment are mounted on pairs of upper and lower guides, move translating to each other under the control of oleodynamic cylinders driven by an electronic control system, thus sweeping the space up to their coming into contact (Fig. 6e).
• the checked person leaves in said space the thing that caused the alarm signal to be activated, the two doors running into it during their movement of translation are locked and cannot reach the end of the stroke.
• the intervention of a guardian is requested so that the doors are allowed to return to their closed position (Fig. 6f).
• FIGs. 7a to 7e the operation of a third embodiment of the admittance system according to the present invention is depicted. It generally consists of a revolving door box provided with a double actuation system of the type already described for the first embodiment.
• a metal thing is detected (Fig. 7b)
• the revolving door rotates by a quarter of turn after the person having been invited to go out (Fig. 7c).
• the four wings close in pairs like scissors sweeping the checked space (Fig. 7d) .
• the normal condition will be restored (Fig. 7e) either automatically in case the doors do not run into any thing or manually in case a pair of wings run into the metal thing that caused the alarm signal to be activated.
