Definitions

  • the present invention concerns the field of robbery-proof accesses, for example to banks or offices, controlled with interlocking doors, and in particular it relates to a driving device for the doors of a robbery-proof box.
  • robbery-proof box a steel load-bearing structure which is designed to be placed in correspondence to a doorway of a protected environment, such as a bank, defining a fixed passage for the working staff and/or the public.
  • the box comprises two motorised doors, usually with a curved shutting panel made of toughened bullet proof glass, to cross in succession, the operating of which is controlled by a logical system that, in normal conditions, prevents their contemporaneous opening to regulate the entrance and exit of the people.
  • a metal detecting device working when a user in entrance is in the space between the doors, both of them being closed, is furthermore usually provided to avoid arms to be let in.
  • the control system has to be provided with accident prevention means, to stop the doors when they find an obstacle in their shutting movement, as it happens when a user is knocked over and trapped by one of them. Moreover, the contemporaneous opening of the doors must be permitted in case of emergency inside the protected environment, for example caused by a fire, to allow a fast outflow of the people.
  • Known robbery-proof boxes have the common feature of using a single motor for driving each door, the opening and closing of which is provided by way of crank gears having a more or less complex configuration.
  • Another object of the invention is to provide a device of the above mentioned type, which is intrinsically equipped with a quite satisfactory degree of safety, so as not to need any additional device of the above cited kind.
  • the driving device is designed to equip a robbery-proof box 1 which is arranged in a known way in correspondence to a doorway of a protected environment, through which the entrance and exit of the working staff and/or of the public have to be regulated.
  • the box 1 comprises a steel support booth 2, defining a substantially cylindrical internal room 3 with passage openings formed in correspondence of two opposite sides 2a and 2b of the booth, in the following indicated respectively as inward and outward side.
  • the device is not visible since it is hidden by a top cover panel 6 of booth 2.
  • Doors 4 and 5 each having a curved shutting panel, are hingedly connected to booth 2 as it will be described below.
  • Operating push-buttons 7 are placed on sides 2a and 2b of the booth, to be pressed to command the opening of doors 4 and 5, in order to allow the passage in both directions across room 3.
  • booth 2 comprises a fixed outer box-type frame 8, having a parallelepiped shape and closed at the top by a panel 8a, in the middle of which a circular opening 9 is formed.
  • a hollow cylindrical body 10, closed at the top by a wall 10a, is housed within opening 9, to define room 3 andtwo accesses to the room itself with a respective opening formed on its lateral surface in correspondence of both sides 2a and 2b.
  • Body 10 has an outside diameter which is slightly smaller than the one of opening 9, so as to define with the latter a slot 11.
  • Each of the two doors 4 and 5 comprises an horizontal support plate, indicated respectively with 4a and 5a, shaped as a circular sector having a width of about 90°, slidable by way of wheels, not shown, on wall 10a of body 10 and pivotally connected in correspondence of its own vertex to a vertical axis 27, coincident with the longitudinal axis of cylindrical body 10.
  • a respective shutting panel dashed in the figures and indicated with 4b and 5b, extends perpendicularly inside slot 11 from each plate 4a and 5a and is connected thereto near its outer edge by way of pins 12.
  • Slot 11 guides the movement of the shutting panels so that each door can move independently between a shutting position, in which its panel is placed in correspondence to a respective of the opposite sides 2a and 2b, intercepting one of the accesses to room 3, and an opening position in which the door, swinging approximately by 90° with respect to axis 27, is placed so as to clear the access itself.
  • the two doors are arranged on opposite sides of booth 2, not to interfere one with each other during their movement.
  • the driving device comprises a disk-shaped cam 13, coaxial to body 10 and pivotally mounted on the latter in a parallel way to wall 10a.
  • a notch 13a is provided on the circumferential profile of cam 13, which is connected for its rotation, by way of a driving cog belt 14, to an electric motor 15 supported by frame 8.
  • Seats 16 and 17 are provided on respective plate 4a and 5a, each mounted with its axis parallel to a corresponding radial edge of the plate and near the edge itself.
  • the seats slidingly support engagement arms 18 and 19, each bearing a respective wheel 20 and 21, pivotally connected to the arm end which is pointed towards cam 13, in the following referred to as first end, to roll around the lateral surface of the cam itself.
  • a spring 22 is arranged around each engagement arm, compressed between the edge of the respective seat and an arm abutment, indicated with 18a and 19a, so as to keep the respective wheel in contact with the cam.
  • Two locking blocks 23 and 24 are fixed over panel 8a near opening 9, in diametrically opposed positions with respect to it, thereby plates 4a and 5a in their shutting position abut with a radial edge against stops 25 extending sideways from blocks 23, 24.
  • a locking seat 26 is also provided, with which the other end of a corresponding arm 18 and 19, in the following referred to as second end, is engageable when the door is in its shutting position.
  • Motor 15 is operated by a microprocessor control system, cooperating wirh a detection network, not shown, to detect the angular position of cam 13 as well as of the two doors.
  • the device according to the invention works in the following way. Supposing the box to be in the configuration shown in figure 3, both the doors are in their shutting position, with the second ends of arms 18 and 19 engaged with locking seats 26 of a respective block 23 and 24 and springs 22 keeping the first ends of the arms in contact with the lateral surface of cam 13.
  • the notch 13a is in an intermediate position between the two wheels, facing outward side 2b. Internal room 3 is therefore closed, not allowing people to get into and out of the protected environment.
  • the driving device has first of all to provide for the opening of door 5.
  • the motor by means of driving belt 14, causes the counter-clockwise angular displacement (according to the plan view of the figures) of cam 13, so notch 13a is brought in correspondence to wheel 21 of arm 19.
  • the device is now in the configuration shown in figure 3.
  • the user can enter room 3 and motor 15, operated by a suitable sensor, turns cam 13 in counter-clockwise direction, so that door 5 is driven once again to its shutting position.
  • Plate 5a abuts against stop 25 of block 24 and, since the motor continues to work, cam 13 keeps turning, causing the disengagement of wheel 21 from the notch and making the second end of arm 19 get into the corresponding locking seat 26, to achieve the configuration shown in figure 4.
  • door 4 has remained shut, locked in its position by the engagement of arm 18 with seat 26 of block 23, the turning of the cam having never brought notch 13a in front of wheel 20.
  • both doors are therefore shut, the user being inside room 3, and the metal detecting device can be operated, if provided.
  • the motor will turn cam 13 to bring notch 13a into engagement with wheel 20 of arm 18.
  • cam 13 by motor 15 in case of a passage of a user in an opposite sense, i.e. from the inside to the outside of the protected environment, is not described in detail because it can be easily drawn from the foregoing. It will be appreciated how the control system, steadily detecting the angular position of cam 13, and of notch 13a as a consequence, will turn the cam in either direction, according to the side from which the opening command comes.
  • figure 5 shows a hypothetical stop of a door panel, in particular the panel 5b of door 5, about halfway in its shutting movement, caused by the accidental interposition of a user's body or part of it.
  • Plate 5a stopped at the point in which its swinging was prevented, while motor 15 continued to turn cam 13.
  • arm 19 is disengaged from notch 13a and the door is free from the control of the driving device, thus being permitted its hand-driven opening without any effort.
  • the device therefore is characterised by a high degree of intrinsical safety and it does not need the use of any active sensor to reverse the direction of rotation of the motor. It will be furthermore appreciated that the disengagement force of arms 18 and 19 from cam 13, fixing the value of the thrust which if acted to the panels stops their movement, is adjustable by suitably setting springs 22, said value having to allow the cam to drive each door in normal operating conditions.
  • the doors can be opened contemporaneously to permit a fast outflow of people, owing to the fact that they abut against limit stops, not shown, even in their opening position.
  • motor 15 instead of inverting its rotation, keeps on driving cam 13 in the same direction.
  • Notch 13a is disengaged from the arm of the already opened door, blocked by one of said limit stops, and gets into engagement with the arm of the other door, continuing to turn so as to achieve its opening.
  • the device according to the invention therefore offers, with respect to known solutions with two independent motors, in addition to the clear advantages above described about safety, the very important one of having a very simple structure, both for having only one motor, and for not comprising any active safety device, with consequent considerably lower costs of construction and of maintenance. Besides, thanks to its very smooth running, it can be equipped with motor means having on the whole a power lower than that of known double-motored solutions.
