Definitions

  • the present invention relates to an antipanic device.
  • Antipanic push bars, handles and touch bars are safety devices designed to ensure quick evacuation even in danger conditions (for example in case of fire), which must be fitted to doors arranged along the evacuation paths in environments that are open to the public and frequented by a certain number of people.
  • This type of device is unidirectional, i.e., allows facilitated evacuation along a predefined direction (generally the direction for exit from the installation environment).
  • the antipanic device allows immediate exit from one of the safety openings of a commercial establishment; likewise, students of a school (or patients of a hospital) might exit very easily and in an uncontrollable manner from one of the safety exits of the building.
  • an electromagnet is installed which is designed to keep the door in the closed configuration and is controlled by the antipanic device.
  • the electromagnet is installed on the jamb and, in the door closure configuration, faces a portion of the leaf that comprises a block made of ferromagnetic material or a bracket that is integral with the leaf and is made of ferromagnetic material.
  • the door In normal operation, the door is closed by simultaneous effect of the bolt of the antipanic device and of the electromagnet (which is normally active and therefore powered in order to apply an attraction force to the respective ferromagnetic abutment that is integral with the leaf).
  • interruption of the power supply of the electromagnet occurs only if the pressure applied by the user is continuous and prolonged for a predefined time (in some cases governed by specific standards and/or laws).
  • This solution entails the persistence of the pressure on the touch bar or push bar (or other actuation element) of the antipanic device, and this can be associated with alarm messages or signals, so that it is possible to be aware that that door will open shortly thereafter.
  • the possibility is offered to predict in advance the imminent opening of a door, by virtue of the delay between the application of the pressure on the element of the antipanic device and the actual opening of the door.
  • the adoption of the electromagnet increases considerably the complexity of the installation activities and requires the execution of masonry work and/or the mounting of additional components on the leaf; furthermore, it is necessary to provide the electric power supply of the antipanic device (in order to allow it to communicate with the electromagnet so as to ensure the interruption of the corresponding power supply after the provided delay time) and of the electromagnet, with functionally associated circuits.
  • the electromagnet causes continuous electric power consumption (of non-negligible value, since the force applied by the magnet must be such as to hold the door closed even in case of pressure by a user), which makes it uneconomical and scarcely sustainable from an environmental standpoint.
  • US5011199 , FR2622240 and WO9708668 each disclose an antipanic device of the known types.
  • EP2319886 discloses an antipanic device using an electromagnet.
  • the aim of the present invention is to solve the problems described above, devising an antipanic device that ensures complete control of an evacuation opening and is easy to install.
  • an object of the invention is to devise an antipanic device that does not require interventions for modification of the leaf and/or of the installation opening.
  • Another object of the invention is to devise an antipanic device that entails very low energy consumption.
  • Another object of the invention is to devise an antipanic device that does not compromise the appearance and design of the installation leaf and of the corresponding evacuation opening.
  • a further object of the present invention is to provide an antipanic device that has low costs, is relatively simple to provide in practice and is safe in application.
  • an antipanic device is generally designated by the reference numeral 1.
  • the antipanic device 1 comprises a boxlike body 2 on which a movable component 2a is articulated which is of a type chosen from a handle, a touch bar, a push bar and the like and accommodates at least one sliding rod 3 for the actuation of the at least one closure element, of a type chosen from a bolt, a spring latch, a latch and the like.
  • the device 1 furthermore comprises at least one kinematic assembly 4, which is associated with the body 2, which is functionally associated with the rod 3.
  • the kinematic assembly 4 is pivoted to the boxlike body.
  • At least one control and management unit 7 is controlled by at least one sensor 8 for detecting the position of the rod 3 and for controlling the power supply of the electromagnet 5.
  • the at least one sensor 8 signals the detected translation to the unit 7, and the unit 7 interrupts the power supply of the electromagnet 5 in order to release, within a predefined and settable time, the tab 6 of the kinematic assembly 4, freeing (i.e., allowing) further translations of the rod 3 for the retraction of the at least one said closure element.
  • the at least one kinematic assembly 4 comprises a first carousel 9, which is pivoted on the pin 10 of the boxlike body 2 proximate to the rod 3, and a second carousel 11, which is pivoted on the pin 12 of the boxlike body 2 proximate to the electromagnet 5.
  • the first carousel 9 comprises a first arm 13 which interferes with the rod 3 at a predefined portion of its stroke and a second arm 14 which abuts against the front of a first protrusion 15 of the second carousel 11 which comprises a second protrusion 16 provided with the terminal tab 16 that abuts against the electromagnet 5.
  • the first protrusion 15 is not perpendicular to the surface of the second arm 14 against which it abuts.
  • the torque applied by the second arm 14 of the first carousel 9 to the second carousel 11 is equal to the ratio between the torque applied to the first carousel 9 by the rod 3 (by means of the first arm 10) and the corresponding second arm 14 (its length), in turn multiplied by the product between the length of the first protrusion 15 the cosine of an angle ⁇ .
  • the angle ⁇ is the offset angle of the first protrusion 15 with respect to the surface of the second arm 14 against which it abuts.
  • the attraction force applied by the electromagnet 5 to the tab 6 is greater than the force, applied by said tab 6 in the direction away from the electromagnet 5, that is applied to the tab 6 by virtue of the torque of said second carousel 11 following a translation of the rod 3 caused by the actuation of the movable antipanic component 2a by a user.
  • the rod 3 can only perform a short portion of translational stroke, until the second arm of the first carousel 9 jams against the first protrusion 15 of the second carousel 11 without being able to move it, since the applied force is not capable of overcoming the magnetic attraction force applied by the electromagnet 5 to the tab 6.
  • the dimensions of the electromagnet 5 are in fact fundamental in the device 1 according to the invention, since said electromagnet 5 must be installable within the boxlike body 2 which must have dimensions that are similar to those of a boxlike body of a traditional antipanic device.
  • At least one kinematic assembly 4 comprises respective elastic means 17 for automatically restoring the inactive configuration (in which the tab 6 abuts against the end face of the electromagnet 5), at which no pressure is applied to the movable antipanic component 2a and the rod 3 is in a retracted limit configuration.
  • the tab 6 can advantageously have shape and dimensions which are complementary to those of the surface of the electromagnet 5 on which it abuts: this dimensional match allows to utilize in an optimum manner the attraction force of the entire surface of the electromagnet 5.
  • the sensors 8 for detecting the position of the rod 3 are at least two.
  • Said sensors 8 are designed to detect an inactive configuration with retracted rod 3, a configuration of maximum translation, which determines the retraction of the closure element by the rod 3, and an intermediate configuration of partial advancement of the rod 3 and abutment of the rod 3 against the first arm 13 of the first carousel 9, with consequent forcing of the second arm 14 on the front of the first protrusion 15 of the second carousel 11.
  • the electromagnet 5 retains the tab 6 and prevents the rotation of the carousels 9 and 11, also preventing the translation of the rod 3 toward the first configuration of maximum translation which would cause the retraction of the closure element.
  • control and management unit 7 comprises appropriate calibration means, for adjusting the duration of the time interval (delay time) that elapses between the actuation of the movable component 2a by the user, with consequent translation of the rod 3 from the inactive configuration to the intermediate configuration, and interruption of the electric power supply of the electromagnet 5.
  • the boxlike body 2 can advantageously comprise, proximate to the pivoting point (pin 12) of the second carousel 11, at least one shoulder 18 for the abutment thereon of the first protrusion 17, at the inactive configuration in which the tab 6 is juxtaposed against the respective surface of the electromagnet 5.
  • shoulder 18 can be used also to anchor part of the torsion spring 17 which ensures the return of the second carousel 11 to the inactive position.
  • the present invention solves the problems described above, devising an antipanic device 1 that ensures complete control of an evacuation opening and is simple to install.
  • the device 1 according to the invention in fact prevents accidental openings of the leaf installed in the opening, since opening is allowed only following the persistence of the pressure on the movable component 2a, so as to ensure that opening is dependent on an actual need of who is applying pressure to the movable component 2a.
  • the antipanic device 1 does not require interventions for modification of the leaf and/or of the installation opening.
  • the device 1 By providing the device 1 also with a power supply unit (of the type of a battery pack), it is not even necessary to provide the connection of the device 1 to an electric power supply grid, minimizing the interventions required for its installation.
  • a power supply unit of the type of a battery pack
  • the antipanic device produces a very low energy consumption: the sizing is in fact such as to allow the use of a low-power electromagnet 5 (and therefore low energy consumptions).
  • the antipanic device 1 does not compromise the appearance and the design of the installation leaf and of the corresponding exit opening, by virtue of the fact that it does not provide for any external apparatus and by virtue of the fact that it has a shape and dimensions that are fully similar to those of an antipanic device of the traditional type.
  • the antipanic device 1 according to the invention is relatively simple to provide and is of low cost: for these reasons, the device 1 according to the invention is to be considered an innovation of assured application.
