Fire swing door with swing swing, preferably automatic and process for their transformation

DESCRIPTION OF THE INVENTION

The field of technology

Fire doors; sliding mechanisms.

View the problem

A technical problem solved by the invention is the construction of automatic fire sliding doors that, even after being locked in an emergency (eg fire), allow passage, while still performing their function of limiting the passage of fire and smoke.

The state of the art

Until now, fire doors with built-in self-closing and a hook-opening system have been installed on evacuation routes and on firewalls, and they can also be equipped with a mechanical forced-opening system when crowds come. Such doors allow the passage and evacuation of persons even in the event of fire. The problem caused by such a door is the force of opening, because when opening it is necessary to squeeze the self-closing spring so that the door leaf closes automatically after passing through the door. Most of all, this problem is an issue in places in buildings where fire doors need to be constantly operational. These are transitions in nursing homes and hospitals where many are frail or in wheelchairs.

Description of the new solution

The object of the present invention is a swing door with a swinging wing, preferably an automatic and a process for their transformation, or a mechanical system which, in the event of a fire, unconditionally closes the sliding door of the automatic door and thus prevents the passage of fire to a protected area, after closing and locking the sliding sash, and opens the swinging wing, enables passage and evacuation through the swinging wing.

The technical problem presented above is solved by such a construction of automatic fire sliding doors, which allows the installation of a swinging door leaf and self-locking on the supporting sliding frame, which is driven by the guide of the automatic door carrier. For the purposes of this application, the term " self-closing " describes a mechanism designed to automatically close the swinging door leaf after passing through in the event of an emergency or situation (eg fire), whereby the self-closing may be performed in various ways. Typically, the self-locking mechanism is designed as a mechanism with a lever that, when the door leaf is opened, tends to spring, which automatically returns the wing to its initial closed position when the sash is pressed. The design of a swing automatic swing door with a swing wing allows passage and evacuation through the door even when the fire door closes due to fire protection. After closing and locking the sliding sash, the previously locked swing sash is unlocked to allow the sash sash to be opened and closed, as in a conventional fire door.

According to the invention, the problem of the difficult opening of fire doors equipped with a self-closing device is solved in such a way that fire automatic sliding doors with swinging wings are installed instead of fire doors. By installing fire automatic sliding doors, we can gain the width of the passage and facilitate the passage. In the normal mode (normal mode), a swing automatic sliding door with a swing wing acts as a normal sliding door, preferably an automatic door that automatically opens when a sensor detects an object in the detection field. In the event of a fire signal, power failure or system failure, the sliding door of the fire door, preferably automatic, is unconditionally closed by the stored potential energy in the form of lifted weights. After closing the sliding sash, it is locked and the swinging sash is opened, which thus becomes active, thereby allowing it to be opened with opening means, preferably with a hook, and automatic closing with self-closing means, preferably with self-closing.

The solution of the invention may comprise more than one sliding wing and more than one swinging wing, the number of sliding and swinging wings being different. Thus, there can be only one swinging wing in the sliding wing, such that some sliding wings comprise at least one swinging wing and other sliding wings do not include any swinging wing.

The sliding wing (11) hung on the supporting wheels (4) comprises a supporting sliding frame (19) on which the swinging wing (21) is suspended by means of hinges (20). The sliding wing equipment comprises: a self-locking device (22), a lock with a hook (23), a locking hook (24), a locking plate (25) and an upper closure assembly (26).

The tensioner assembly (7) comprises a base with guide (27), a pressure spring (28), a yoke with guides (29), a toothed rack (30), a pinion (31) mounted in the base, a pinion (32) mounted in the housing (33). , toothed rack (34) and toothed rack (35).

The swinging latch assembly (26) can be mounted in a carrier sliding frame (19) and comprises a housing (36), a two-latch (37) and a return spring (38).

The retainer assembly (16) comprises a fixed housing (40), a toothed lever (41) and a torsion spring (42) in a fixed column (wall) (39); and a toothed lath (44), which is guided in the guide (18), is attached to the movable sliding wing by means of a support (43).

Swing-wing fire doors, preferably automatic, are designed to function as normal automatic doors under normal conditions. In the event of an active fire signal, power failure, or system failure, the sliding door leaf (11) is unconditionally closed, but the passage or escape is still possible through the swinging wing (21), which is mounted on the sliding frame by means of hinges (20). (19) and fitted with a self-closing device (22) which automatically closes the swing arm when opened. The door is equipped with a mechanical system that ensures the sliding wing is closed and locked unconditionally (11). The function of closing the sliding wing is taken care of by hanging and lifting the weight (10) on the steel rope (9). The lifted weight for the purposes of this application represents the stored potential energy used to close the sliding door in the event of an emergency or event. For the lifting of the weights and the tension of the spring on the tensioner assembly (7), a retractor (6) is provided with a retarding brake. which, when lifting weights (10), strains the rope handle (8).

In the specific embodiment, a swing automatic swing door with a swing wing is provided, which in the normal mode acts as an automatic swing door, designed in such a way that passage in the swing wing is enabled. The door is designed in such a way that the swinging sash (21) is fixed to the supporting sliding frame (19) by means of hinges (20), the swinging sash (21) is locked in the sliding mode and cannot be opened so that the supporting sliding frame (19) ) is locked in the fire mode, the swing arm (21) is unlocked in the fire mode and can be opened with a hook from the outside and the inside.

According to the invention, a shear bracket which prevents oscillation and swinging of the swinging wing in the sliding mode is arranged by attaching a sliding upper profile (46) to the gap between the stationary upper profile (46) of the supporting sliding frame and the rotating profile (47) of the swinging wing (46). ) holding profile (48) and opposite facing holding profile (48) to the rotating profile (47).

The door according to the invention also comprises a tensioner, which has a stored potential energy in the form of a compressed spring in the sliding mode of operation, and this energy is used to release the swinging wing and lock the supporting sliding frame during the transition from the sliding mode to the fire mode of operation. from the stored potential energy in the form of lifted weight that is used to close the sliding door in the event of an emergency or event. The tensioning according to the invention is carried out in such a way that the springs (28) on the guide yoke (29) are compressed while lifting weights (10) by means of a rope clip (8) attached to the steel rope (9) so as to move when the spring (28) is compressed the guide yoke (29) and a toothed rack (30) which rotates the pinion (31) and the pinion (32), which longitudinally moves the toothed rack (34) connected to the control rod with a beak attachment (12) and in the opposite direction toothed rack (35) tied to steering column (13).

The door element of the invention retained the sliding frame, where a lever mounted on a fixed wall in a fire mode engages a movable toothed bar that is attached to the sliding frame and held so that the sliding frame cannot be removed due to the weight of the swinging wing. According to an embodiment, the retainer is designed so that in the housing (40) it is fixed to the fixed wall (39) by a toothed lever (41), which is tilted by the torsion spring (42) when the lever (15) is released, so that when it slides the wing enters the closed position, the teeth of the toothed lever (41) are gripped to the supporting sliding frame via a bracket (43) by a fixed toothed bar (44).

Preferably, the hook, which is used to open the swinging wing in fire mode of operation, is positioned so as not to interfere with the movement of the sliding wing. In this case, the hook (24), preferably engaging, is connected to the lock (23) and mounted in the space between the door element (49) (usually the pile (49)) and the front plane (50) of the swinging wing (21). Alternatively, an element other than transparent or opaque material may be used instead of the pile (49).

A lateral guide in which the slider of the door, preferably automatic, slides, and is open downwards so that no foreign objects which obstruct the slide in the guide can enter it, according to the invention, with the slider guide (18) open downwards and laterally attached to wall (51).

In normal mode, the automatic swing door with sliding sash operates sliding (in sliding mode) when the slider sash assembly (11) is moved to the "open" position by means of gearbox (2) and traction element (3). and the "closed" position, which can be done either with an electric motor or in a simplified version manually. In the sliding mode of operation, the swinging wing (21) cannot be opened as it is locked by the latch (37).

When starting and placing the automatic fire door with swinging sash in normal sliding mode, the retractor (6) lifts the suspended weight (10) to the upper position on the steel rope (9). When lifting weights, the rope clip (8) is attached to the steel rope (9) by the tensioning springs (28) on the tensioner assembly and at the same time it moves the yoke with guides (29) to the sliding mode. When the yoke moves with the guides (29), the toothed rack (30) also moves, thereby rotating the pinion (31) and the sprocket (32), which longitudinally moves the toothed rack (34) connected to the control rod with a beak attachment (12) and a toothed rack. the bar (35) is connected to the steering column (13). As the toothed rack (34) and the toothed rack (35) are each driven by a sprocket (32) each on the opposite side, the toothed rack (34) and the control rod with a beak attachment (12) are moved forward, the toothed rack (35) with the control rod (32). 13) it moves backwards.

When the steering column is moved with the beak nozzle (12) forward, the beak on the steering column moves away from the position of the open swinging wing, releasing a spring (38) which pushes the latch (37) into the groove of the locking plate (25), thus locking the swinging wing (21).

When the steering column (13) is moved back to the steering column, an obliquely trimmed attachment (14) lifts the lever (15), which raises the toothed lever (41) via the connecting rod (17), thereby releasing the toothed bar (44) and the sliding wing (11), which are related.

The door is ready for sliding mode after lifting weights (10) to the highest position. At that time, the rope handle (8) strains the springs (28) on the tensioner (7), locks the swing arm (21) and releases the toothed bar (44).

In the event of an emergency, that is, including and not limited to an activated fire signal, power failure or system failure, the door enters fire mode.

In the transition from sliding mode to fire mode, the retractor (6) releases the steel rope (9), the weight (10) pulls the steel rope (9) and the rope holder (8) attached to it, which hits the nozzle (45) and pulls sliding sash (11) in the closed position where it is locked by the monostable electric lock (5). When the steel cable (9) is released and the rope clip (8) is moved, the spring force (28) on the tensioner pushes the steering column with the beak (12) backwards through the gear train and the steering column (13) forward.

Moving the steering column (13) and the attachment (14) forwards the lever (15), while the torsion spring (42) pushes the toothed lever (41) into the teeth of the toothed rack (44), thereby retaining the frame of the sliding wing (19). ) that it cannot hang when the swinging wing (21) opens. If the sliding leaf (11) is closed in the event of a fire alarm, the teeth of the toothed lever (41) snap into the teeth of the toothed rack (44), but if the sliding leaf (11) is open during the fire alarm, the toothed lever (41) is lowered downwards. , in this case, the toothed bar (44) encounters a toothed lever (41), which lifts it, which then engages the teeth of the toothed rack (44) in the closed end position of the sliding wing.

When the control rod is moved with the beak nozzle (12), the beak pushes the upper arm of the double latch (37) out of the closed swinging wing position and at the same time pushes the lower arm of the two latch (37) out of the locking plate groove (25), thereby opening the swinging wing (25). 21). If the wing is in the closed position at the time of the fire alarm, the steering column with the beak nozzle (12) pushes the double latch (37) out of the locking plate groove (25), or if the sliding wing is in the open position during the fire alarm, the upper arm the two-way latch (37) runs into the steering column with the beak nozzle (12) and pushes the two-way latch (37) out of the locking plate groove (25).

The automatic swing door with a swing door is in fire mode when the weight is closed by the swing door and is locked by the electric lock, while the swing door is opened and the slide frame is blocked.

At the end of the emergency, however, the door enters regular mode of operation by means of the solutions of the present invention. For this purpose, the door according to the invention comprises a swing wing latch, in which the return spring locks the swing wing after the fire regime ceases to operate. The latch works by affixing a pivot housing of a swinging wing (36) to a stationary profile of the supporting sliding frame (19) in which a tensioned spring (38) pushes the lower arm of the guided two-latch (37) into the groove of the locking plate (25) attached to a rotatable swinging wing (21).

It is to be understood that the described solution can also be implemented in a different design that does not alter the essence of the invention.
