Definitions

• the subject matter of the present invention is a system that facilitates the opening of a partitioning door with hinged leaf between environments at different pressures.
• the partitions between the pressurized environment and the atmospheric pressure environment are provided by technical doors, which often also have the function of an escape route and fire protection (panic exits and fire doors) .
• a door with dimensions of 1.2x2.5 m has an area of 3 sqm. If subjected even to an overpressure of only 100 Pa, the door must withstand a thrust of 30 kg.
• 100 Pa corresponds to 0.001 Bar, i.e. one millibar.
• the pressure difference, and thus the thrust reduces to zero after rotating the leaf of the door by at least 10 degrees.
• Doors are known for partitioning rooms at different pressures that are provided with a system facilitating the opening of said door, for facilitating the opening thereof.
• such a system facilitating the opening involves generating an impulsive force between the door frame and said door leaf in order to open the leaf by an angle of at least 10°.
• Such a system is driven either by a presence sensor or by a sensor connected to the opening handle of the door.
• the system comprises a pusher that, in the opening phase of the leaf, is instantly pushed out of a housing so that it extends in length between the leaf and the frame. When the leaf is open, the pusher automatically returns to the housing.
• the door is not completely opened by the user, it is free to close due to the intervention of a traditional door closing mechanism.
• Such a system facilitating the opening has a first limitation linked to the fact that the sudden opening of the leaf, although only by a few degrees, may startle the user and risk striking them.
• a second limitation is linked to the fact that the closing of the leaf is not controlled, as it is subject to the action of the pressure difference between the two environments.
• the closing of the leaf may be violent. There is therefore a risk that a user may be struck by said leaf.
• the main object of the present invention is to eliminate in whole or in part the drawbacks of the aforementioned prior art by providing a system facilitating the opening of a partitioning door between environments at different pressures that allows for the controlled and progressive opening of the leaf without sudden movements.
• a further object of the present invention is to provide a system facilitating the opening of a partitioning door with hinged leaf between environments at different pressures, which allows the leaf to be closed in a controlled and progressive manner without sudden movements.
• a further object of the present invention is to provide a system facilitating the opening of a partitioning door with hinged leaf between environments at different pressures and which is simple and economical to manufacture.
• a further object of the present invention is to provide a system facilitating the opening of a partitioning door with hinged leaf between environments at different pressures and which is simple and easy to operate.
• the system 1 is intended to be installed on a partitioning door D with hinged leaf between two environments E1, E2 having different pressures.
• the door D is a fire door or a panic door and comprises a fixed support frame F and a leaf L hinged to said frame F (hinged leaf) to rotate about a leaf rotation axis Y1 in the environment E2 at higher pressure.
• the system 1 is intended to be installed on the side of the door D facing the environment E2 at higher pressure.
• the system 1 comprises an anchoring base 10 which is intended to be fixed to the leaf L of the door D.
• said anchoring base 10 may consist of a metal plate.
• the system 1 further comprises a support structure 20 hinged to said anchoring base 10 to rotate around a system rotation axis Y2 parallel to the leaf rotation axis Y1 by means of at least one hinge 11.
• the support structure 20 is intended to support the operating components of the system 1.
• the support structure 20 may consist of a box-like body divided into:
• the system 1 further comprises a locking device 30 which is electro-actuated and is adapted to rotationally constrain said support structure 20 to said anchoring base 10 when electrically powered.
• said locking device 30 consists of an electromagnet which is associated with said support structure 20 and is adapted to hold the anchoring base 10 magnetically constrained to said support structure 10 only when electrically powered.
• the locking device 30 deactivates and leaves the rotation around the system axis Y2 free between the anchoring base 10 (associated with the leaf L of the door) and the support structure 20 (with the associated operating components of the system 1).
• the system 1 may comprise a return spring 21 that interconnects the anchoring base 10 to the support structure 20.
• this spring 21 upon restoration of the electrical power supply, allows the electromagnet (now powered) to be brought into contact with the anchoring base 10, which is made of a ferromagnetic material or is provided with a plate of ferromagnetic material.
• system 1 further comprises:
• the linear actuator 40 is operatively drivable for moving said elongated stem 50 along a longitudinal drive axis X so as to vary the distance between the support structure 20 and a first end 51 of said elongated stem 50 between:
• said linear actuator 40 consists of a mechanical jack operatively associated with an electric drive motor 41 (which ensures electro-actuation).
• the elongated stem 50 consists of a helical screw 50 which is operatively rotatable by said mechanical jack 40 about said longitudinal drive axis X to move the related first end 51 between said first stroke end and said second stroke end.
• mechanical jack (or screw jack) is understood to mean a linear actuator which transforms the rotary motion of a shaft into a translational motion of a stem by means of a helical torque.
• the linear actuator may consist of an electric cylinder, although the solution with a mechanical jack is wholly preferred.
• the system 1 comprises a drive control 60 for driving the linear actuator 40 (mechanical jack) so as to increase the distance between the support structure 20 and the first end 51 of said elongated stem 50 (helical screw).
• this drive control 60 may be activated by a user who intends to open the door D. Therefore, in the case of a closed leaf, the activation of the drive control 60 drives the linear actuator 40 (mechanical jack) which in turn sets the elongated stem in motion (rotating the helical screw) by progressively bringing the first end 51 of said elongated stem 50 (helical screw) from said second stroke end to said first stroke end and thus progressively pushing the leaf D from a closed position to a semi-open position.
• the linear actuator 40 mechanical jack
• the locking device 30 is electrically powered in the same way as the linear actuator 40 (mechanical jack), it constrains the anchoring base 10, and thus also the leaf L of the door D, to the support structure 20, to which the linear actuator 40 (mechanical jack) is in turn constrained.
• said drive control 60 is intended to be operatively associated with an opening handle H of said door D.
• the system 1 facilitates the opening of a partitioning door with hinged leaf between environments at different pressures, allowing for a controlled and progressive opening of the leaf without sudden movements.
• the linear actuator 40 (in particular if consisting of a mechanical jack) is able to provide the force necessary to overcome the thrust exerted against the leaf L due to the pressure difference between the two environments E1 and E2.
• the movement generated by the linear actuator on the elongated stem results in a progressive thrust on the leaf, generating a controlled and not abrupt motion of the leaf until the leaf is brought to a semi-open position (at least 10°).
• the system 1 according to the invention does not cause the leaf to suddenly open; therefore, opening the leaf will not startle the user. In any case, since the opening is progressive, any impact with the user would be minor.
• the system 1 comprises a management and control unit 70, programmed to drive the linear actuator 40 (mechanical jack) according to predefined automatic operating modes.
• the system 1 comprises at least a first position sensor 61 that is intended to be installed on said door D to detect the position of the leaf L with respect to the frame F and thus the open or closed state of the door D.
• the system 1 comprises an abutment body 52 (e.g., consisting of a rigid Teflon pad) which is associated with the first end 51 of said elongated stem 50 (helical screw) and is provided with at least one second position sensor 62, which in use is adapted to detect the contact between the abutment body 52 and the frame F of the door D.
• abutment body 52 e.g., consisting of a rigid Teflon pad
• second position sensor 62 which in use is adapted to detect the contact between the abutment body 52 and the frame F of the door D.
• the system 1 may comprise a pair of guide rods 53 parallel to said elongated stem 50 (helical screw) and adapted to keep said abutment body 52 stable.
• the system 1 may comprise a profile 54 intended to be associated with the frame F of said door D at the section in which said abutment body 52 is intended to come into contact.
• said management and control unit 70 is programmed to:
• said management and control unit 70 is programmed to activate the linear actuator 40 (jack) so as to bring the elongated stem (helical screw) from the first stroke end to the second stroke end as soon as the second position sensor 62 detects the contact between the abutment body 52 and the frame F, thereby allowing a controlled closing of the leaf L.
• the system 1 allows for a controlled and progressive closing of the leaf without sudden movements.
• the system 1 offers a wide range of operating modes which will now be recalled in reference to a preferred embodiment using a mechanical jack:
• the invention allows numerous advantages to be obtained, which have already been described in part.
• the system 1 facilitates the opening of a partitioning door with hinged leaf between environments at different pressures according to the invention and allows for a controlled and progressive opening of the leaf without sudden movements.
• the system 1 allows for a controlled and progressive closing of the leaf without sudden movements.
• system 1 makes it possible to:
• the system 1 is simple and economical to manufacture.
• the system 1 is simple and easy to activate.
