Description

"MODULAR DEVERSIBLE AND POLIVALENT ANTIPANIC CLOSURE DEVICE"

FIELD OF THE INVENTION

This invention relates to a modular design device that has a reversible character and can be operated in a versatile manner, which is applicable to panic closures that are installed in emergency exit doors and that have a main lock mechanism, with or without closing latch, and / or upper (over the lintel) and lower (over the threshold), and / or lateral closing points on the frame, whose main lock is operated by a bar that is installed transversal mode on the door.

STATE OF THE PREVIOUS TECHNIQUE In this field two types of panic bar are commonly known and used. One of them consists of a rotating bar that, by means of connecting rods, is articulated at its ends to make a folding on the door; This guy is known in this field by his name in English, "pushbar" that will be used in the future. The other type consists of a bar that incorporates an outer casing with linear movement capacity perpendicular to the door; This guy is known in this field by his name in English, "touchbar" that will be used in the future.

The current situation is that there are two different concepts of panic bar (pushbar and touchbar) and, within each of them, there are all the variants mentioned above: a main lock that has a latch or lacks it; that the main lock must also actuate lateral forwarding located at a different height from the door; that from the main lock some upper and lower forwardings must also be activated.

Well, today each of these options responds to its own and exclusive design; in such a way that the manufacturers and the distribution chain of this kind of product bear great problems of design, material supply, production, storage and distribution. EXPLANATION FOR THE INVENTION AND ADVANTAGES

Faced with this state of affairs, this invention advocates a modular and compact design device that will allow its application for the various variants of execution existing today, described above.

To this end, the proposed device comprises a main lock in which a compact modular kinematic chain is installed which, taking as a positional reference the operational situation of the main lock in the door, consists of an upper bent lever, a lower bent lever, a first disc, a rotating shaft, vertical and sliding upper plate and lower plate; the upper and lower angled levers are in a vertical plane and transverse to the door, with its concave or inner angle facing the door, are articulated at its elbow in symmetrical places with respect to the rotary axis, they are capable of tilting between closed and closed positions open the lock and have two first arms and second arms, the first arms are extended aerially to the mutual encounter and their ends overlap in an extreme part where the first arm of the second lever has a first pin that with sliding adjustment crosses an opening torn from the first arm of the first lever, and the second arms extend transversely to the door and at its end are pivotally articulated with respect to respective first pin and second pin having their ends with sliding adjustment in vertical slots of the box of Ia main lock that are parallel to the door and that its extreme positions are consistent with the closed and open positions of the lock; The first disc is between one of the angled levers and a side wall of the lock box, and has a second stud that is applied against the inside edge of one of the angled levers, whose first disk is capable of reversible mounting on the shaft. rotary in two diametrically opposite positions; The upper vertical sliding plate and the lower vertical sliding plate are parallel to the door, are guided laterally in the housing lock, are superimposed on each other, one of them attached to the floor of the lock box, and each one of them forms a pair of collateral laces in which a respective one of said first pin and second pin is coupled, whose upper vertical plate and Lower vertical plate are capable of sliding between both extended and retracted positions, with respect to the center of the lock case, which are respectively coincident with said closed and open lock positions. In this constitution it is fulfilled that, for the part towards the closing frame and through the torn opening of the first arm of the first lever, the first stud protrudes in a part that is applied under a tail of a rotary latch that is susceptible to swing between extended and retracted positions such that, in the extended position, this protruding part of the first stud, and therefore the first arms and the transverse stud of the first disk are in their position closest to the door, the first pin and the second pin are at the ends of their respective vertical grooves that are farther apart from each other, the upper vertical plate and the lower vertical plate are from each other in the furthest positions, and in the retracted position, this protruding part of the first stud, and Therefore, the first arms, the transverse pin of the first disc, are in their position furthest from the door, the first pin and the second pin. they are at the ends of their respective vertical grooves that are closer to each other, the upper vertical plate and the lower vertical plate are each other in the closest positions.

This kinematic chain behaves so that, when the first arm of any one of the cranked levers is driven from the resting or closed lock position, this cranked lever rotates and drags the first arm of the other cranked lever so that symmetrical. This rotation of the cranked levers is used so that, through the first pin and the second pin, the second arms thereof drive the vertical sliding of said plates. upper and lower which, according to the invention, have means for joining with fallebas that operate on forwards that establish upper and lower closing points, and / or lateral closing points different from that of the main lock; with which, the opening position will occur in these resends. At the same time, if the main lock is provided with a rotary latch, it will be retracted to the opening position under the impulse exerted on its tail by the protruding part of the first stud belonging to the first arm of the lower bent lever. The rotation of the first arms of the angled levers can be achieved in various ways. One of these is that the rotary axis is coupled with the corresponding connecting rod of a pushbar. Then, when the pushbar is activated, the connecting rod rotates and rotates the rotating shaft in which the first disc is keyed, and the second stud of this first disc is the one that drives the rotation of the first arm of one of the cranked levers; The first disc can be mounted on the rotating shaft in two positions that are diametrically opposite, so, depending on this position, the second bumper will drive on the first arm of the upper bent lever or on the lower bent lever; This means that the same mechanism can be used interchangeably for right and left doors, just by turning it around. In this simple way, the modular design created for the main lock is applicable for a pushbar and reversibly.

To apply it to a touchbar, the invention contemplates two options. A preferred option consists in the existence of a "Y" shaped rocker that extends horizontally with its convex angle in opposition to the door, which operates according to a plane transverse to the door with its foot articulated in a support attached to the door. same and that at its end towards the main lock it has two nails that are applied under the lower edge of the first arms of the angled levers, while at its opposite end to the nails this rocker is articulated to the mobile external cover of a touchbar By pressing on this cover of the touchbar the swinging of the rocker occurs within the two quadrants furthest from the door and the nails thereof are those that exert the drive that in the case of the pushbar was entrusted to the second stud of the first disk. That is, the same kinematic chain based on the angled levers is applicable for a touchbar, with or without a latch, and reversibly.

Another application option for a touchbar is that in the upper vertical plate a python protrudes, which, in the vertical direction, has a tooth that belongs to a rotating lever that operates in a plane parallel to the door, which rotates with respect to a base that is anchored to the door and that with the possibility of rotation is attached to a strap that extends horizontally and parallel to the door and that is propelled towards the main lock when the mobile external cover of a touchbar is pressed, strap that moves in length a stroke such that it drives the rotation of the rotary lever in such a way that it produces a linear travel of the tooth that is equal to the operative displacement of said upper sliding plate between their respective closed lock and open lock positions. This solution is applicable for touchbars that respond to a more traditional concept in which, when you press your mobile cover, you rotate measures that operate in the two quadrants closest to the door; This turn becomes a longitudinal impulse of the tie rod which, now, is used to rotate the rotary lever which, with its tooth, pushes the python of the lower sliding vertical plate so that, through the second pin that is coupled with the second arm of the lower bent lever, make the latter rotate by dragging the upper bent lever which, in turn, by means of its second arm coupled with the first pin, will cause the upper vertical plate to slide in the opposite direction to that of the Ia bottom vertical plate.

This mechanism is also directly reversible for right or left doors, just by turning it, since when the touchbar acts, said brace will always move in the same direction with respect to the main lock.

Another peculiarity of the invention consists in that the rotary latch incorporates in its bosom a rotating plate of vertical axis which, inside the lock box and hovering behind the rotary latch, presents a dorsal appendix; in relation to the position of the extended rotary latch, or of the closed main lock, the turntable is able to oscillate between two positions, a position that is driven by a spring and in which an arcuate front edge itself appears with respect to the plane of the latch rotating that attacks its strike in the frame of the door while the dorsal appendix is deviated from a first projection formed in the upper sliding plate, and another position in which said arched front edge of the turntable is retracted in the breast of the rotary latch and the dorsal appendix is facing and next to the first projection; and in relation to the state of the retracted rotary latch, or of the open main lock, the arched leading edge of the rotating plate is adjacent to the edge of the actuating window of the rotary latch. This mechanism provides security against attempts to violate the closure by the method of influencing the front of the latch with the edge of a credit card or similar inserted by the slot between the door and the frame; when such a thing is attempted, the edge of the card first hits the turntable, which tilts and opposes its dorsal appendix to the first projection of the lower vertical plate, with which the retraction of the latch is prevented; when the retraction of the latch is produced by the action of the kinematic chain in the normal opening maneuver, the dorsal appendix releases the position of the first projection. Another peculiarity of the invention is that there are lateral closing points, or lateral forwarding, that comprise a forwarding box, a rotary latch provided with a rotating plate with a dorsal appendix, a first vertical sliding rule that is on track between the bottom and side walls. of the forwarding box and a second disk; The first vertical sliding rule It has means at both ends for its attachment to a fault, it has a side wall provided with a pair of protruding buttons located in opposite diametral positions with respect to the rotation of the second disk, and it has a second projection capable of constituting a stop for the dorsal appendix of Ia turntable housed in the rotary latch; The second disk is installed in a pivot axis that has sliding adjustment in a vertical slide of the lateral wall of the first vertical ruler slide, this second disk has a pair of radial recesses in diametral opposition and that, in a state of rest or of closed lock, are applied laterally on said buttons in reverse, one above and the other below, and in this second disk there is a prominence that in said resting state is applied below the tail of the rotary latch. When, by means of a failure, the first vertical ruler is displaced in one direction, the button that in that sense is applied against a radial recess pushes on it and rotates the second disc, which with its prominence drives on the tail of the latch making Let it retract. Note that this solution is also reversible.

Another peculiarity of the invention is that there are upper and lower closing points, or vertical forwarding, comprising a forwarding box, a rotary latch provided with a rotating plate with a dorsal appendix, a second vertical sliding ruler that is on track between the bottom walls. and sides of the forwarding box and a rotating square; The second vertical sliding rule has rear means for its attachment to a fault, it is capable of sliding between respective upper and lower positions that are coincident with those of extended and retracted rotary latch, and this second vertical sliding rule has a side wall provided with a fin; The rotary square operates in a vertical plane and has a first branch applied under the tail of the rotary latch and a second branch which, with respect to the opening stroke of the second vertical sliding rule, is applied in front of the fin formed in Ia Side wall of this second vertical sliding ruler. When the latch is extended in its closed position and, by means of the failure, the second sliding vertical ruler is pulled, the flap of its lateral wall drives the second branch of the rotary square and, when turning it, its first branch raises the tail of the latch producing its retraction. Since, as it is evident, the vertical displacement of the fallebas with respect to the main lock (1) always occurs in the same direction to open and in the opposite direction to close, it turns out that any one of these vertical forwardings is indistinctly valid for upper closure as for lower closure; that is, it is reversible.

Another peculiarity of the invention is that the fault has a "C" profile that forms a straight-walled slide inside it, along which a slide with a turning capacity is installed in an anchor moored to the door. . This solution enables a rotation of the fault with respect to its anchorage moored in the door, facilitating the placement and the same and its correct alignment, compensating eventual errors of assembly planning.

With regard to the drawings and references listed above, a preferred embodiment of the object of the invention, referring to a modular device of reversible and versatile panic closure, of the closures that are installed in exit doors of exit is illustrated in the attached drawings emergency and that have a main lock mechanism, with or without closing latch, and / or upper (over the lintel) and lower (over the threshold), and / or lateral closing points over the frame stud, whose main lock is operated by a bar that is installed transversely on

The door, either a rotating bar that, by means of connecting rods, is articulated at its ends to make a folding on the door (hereinafter, "pushbar", by its name in English) or by means of a bar that incorporates an outer casing with linear movement capability perpendicular to the door (hereinafter, "touchbar", by its name in English). As Figure 1 illustrates, the device according to the invention comprises a main lock (1) in which a compact modular kinematic chain is installed which, taking as a positional reference the operational situation of the main lock (1) in the door (4) , it consists of an upper angled lever (2), a lower angled lever (3), a first disc (5), a rotating shaft (6), vertical and sliding upper plate (7) and lower plate (8); the upper (2) and lower (3) angled levers are in a vertical plane and transverse to the door (4), with its concave or inner angle facing the door (4), are articulated at its elbow in symmetrical places with respect to the Rotary axis (6), are capable of tilting between closed and open positions of the lock (1) and have two first arms (2a, 3a) and second arms (2b, 3b), the first arms (2a, 3a) are they extend aerially to the mutual encounter and their ends overlap in an extreme part where the first arm (3a) of the second lever (3) has a first pin (3c) that with sliding adjustment crosses a torn opening (2c) of the first arm ( 2a) of the first lever (2), and the second arms (2b, 3b) extend transversely to the door (4) and at its end are hinged in relation to respective first pin (9) and second pin (10) that have their ends with sliding adjustment in vertical slots (11) of the box ( 1a) of the main lock (1) that are parallel to the door (4) and that its extreme positions are consistent with the closed and open positions of the lock (1); The first disk (5) is between one of the angled levers (2, 3) and a side wall of the lock box (1a), and has a second stud (12) that is applied against the inner edge of one of the angled levers (2, 3), whose first disc (5) is capable of reversible mounting on the rotating shaft (6) in two positions diametrically opposed; the upper vertical sliding plate (7) and the lower vertical sliding plate (8) are parallel to the door (4), are guided laterally in the lock box (1a), are superimposed on each other, one of them attached to the floor of The lock box (1a), and each of them forms a pair of collateral fittings (7a, 8a) in which a respective one of said first pin (9) and second pin (10), whose upper vertical plate ( 7) and lower vertical plate (8) are capable of sliding between both extended and retracted positions, with respect to the center of the lock case (1a), which are respectively coincident with said closed and lock positions (1). ) open. The upper vertical plate (7) and the lower vertical plate (8) have joining means with fallebas (14) that operate on forwardings that will be explained in detail below and that establish upper and lower closing points (see figures 29 and 30 ), and / or lateral closing points different from that of the main lock (1) (figures 23 to 26). It is very frequent the incorporation of a latch in the main lock (1), so that, according to the invention for this purpose, it is fulfilled that, on the part towards the closing frame and through the torn opening (2c) of the first arm (2a) of the first lever (2), the first pin (3c) protrudes in a part that is applied under a tail (13a) of a rotary latch (13) that is capable of tilting between extended and retracted such that, in the extended position, this protruding part of the first stud (3c), and therefore the first arms (2a, 3a) and the transverse stud (12) of the first disk (5) are in their closest position to The door (4), the first pin (9) and the second pin (10) are at the ends of their respective vertical grooves (11) that are further away from each other, the upper vertical plate (7) and the lower vertical plate (8) are with each other in the furthest positions, and in the retracted position, this part protruding from the first stud (3c), and therefore the first arms (2a, 3a) and the transverse stud (12) of the first disk (5) are in their position furthest from the door (4), the first pin (9 ) and the second pin (10) are at the ends of their respective vertical grooves (11) that are closer to each other, the upper vertical plate (7) and the lower vertical plate (8) are with each other in the closest positions. The described device constitutes a kinematic chain of great constitutive and functional simplicity that, as explained above and will be seen in detail below, will be a basic module to apply it interchangeably for pushbar or touchbar panic bars, with character of reversible employment and that is capable of being operated by various driving means. Its operation is based on the mutual coupling of the upper (2) and lower (3) cranked levers, by which they make a turn in opposite directions regardless of the driving means used and whatever the arm thereof on the that impulse is applied.

In the case of a pushbar (figures 8 to 11) the connecting rod (15) of the same will be mounted on the rotary axis (6) so that, when operated, the rotation of the latter causes the second stud (12) of the first disk (5) push up (in Figure 8) on the first arm (2a) of the upper bent lever (2); by means of the mutual coupling established by the first pin (3c) (figure 9) the lower bent lever (3) is rotated; the coupling of the second arms (2b and 3b) with the respective first pin (7) and second pin (8) coupled in the fittings (7a and 8a) of the upper (7) and lower (8) sliding plates, these are driven to move (figure 9) towards the center of the lock box (1a) in mutual opposition; when there are lateral (27) and / or vertical (33) forwardings, the movement of these plates (7 and 8) will be transmitted to them through the fallebas (14); If this main lock (1) incorporates a rotary latch (13) (as considered in Figure 1), in this described maneuver it will be retracted by the thrust that its first pin (3c) exerts on its tail (13a). Reversibility is obtained by mounting the first disc (5) in a diametrically opposite position, as illustrated in Figure 11. For the application of the device recommended to a touchbar, the present invention contemplates two variants. One of them, preferably, consists (figures 12 to 15) in which there is a "Y" shaped rocker (16) that extends horizontally with its convex angle in opposition to the door (4), which operates according to a plane transverse to the door (4) with its foot articulated in a support (18) attached to it and that at its end towards the main lock (1) has two nails (17) that are applied under the lower edge of the first arms (2a, 3a) of the angled levers (2, 3), while at its opposite end to the nails (17) this rocker arm is articulated to the external mobile cover of a touchbar. Due to its shape and assembly, as can be seen in the figures, this rocker (16) swings in the two quadrants that are furthest from the door (4). When the touchbar is pressed by pressing on its mobile cover, the rocker (16) located in the resting position shown in figures 12 and 13, tilts towards the final position shown in figures 14 and 15, with the result that the nails ( 17) produce the opening rotation of the upper cranked levers (2 and 3) and the retraction of the rotary latch (13).

The other variant consists (figures 16 and 17) in which in the upper vertical plate (7) a python (19) protrudes which, in the vertical direction, has a tooth (21) that belongs to a rotary lever (20) applied laterally. It operates in a plane parallel to the door (4), which rotates with respect to a base (22) that is anchored to the door (4) and that with the possibility of rotation is attached to a tie rod (23) that extends horizontally and parallel to the door (4) and which is propelled towards the main lock (1) when the external mobile cover of a touchbar is pressed, a strap (23) that travels in length a stroke such that it drives the rotation of the rotary lever (20 ) in such a way that it produces a linear path of the tooth (21) that is equal to the operating displacement of said upper sliding plate (7) between their respective closed lock and open lock positions. Starting from the resting position (figure 16), when pressing on the cover The internal mechanism of the touchbar produces a tension on the tie rod (23) that rotates the rotary lever (20) so that the tooth (21) of this pushes on the python (19) and produces the displacement of the lower vertical plate (8); then it carries with it the second pin (10) by tilting the lower angled lever (3) which, in turn, drags the upper angled lever (2) in rotation, which through the first pin (9) causes the plate upper vertical (7) slides in the opposite direction than the lower vertical plate (8), while the first pin (3c) of the upper bent lever (2) drives on the tail (13a) of the rotary latch (13) so that it retracts (figure 17).

To establish a security against the aforementioned attempts of violation of the closure by the classic method of the credit card, the rotary latch (13) incorporates (figures 18 to 22) in its bosom a rotating plate (24) of vertical axis that, inside of the lock box (1a) and peeking out from behind the rotary latch (13), it presents a dorsal appendix (24a); in relation to the position of extended rotary latch (13), or of main lock (1) closed, the turntable (24) is able to oscillate between two positions, a position that is driven by a spring (26) and in the that an arched front edge itself appears with respect to the plane of the rotary latch (13) that attacks its strike in the frame of the door (4) while the dorsal appendix (24a) is deviated from a first projection (25) formed in The upper sliding plate (7), and another position in which said arched front edge of the rotating plate (24) is retracted within the rotary latch (13) and the dorsal appendix (24a) is facing and next to the first projection (25); and in relation to the state of the retracted latch (13) retracted, or of the main lock (1) open, the arched leading edge of the turntable (24) is adjacent to the edge of the actuation window of the rotary latch (13). In the rest state (figure 18) the turntable (24) appears from the front of the latch (13) and, if the normal opening maneuver is then performed, its dorsal appendix (24a) does not interfere (figure 19) with the first projection (25) of the plate vertical sliding top (7); however, outside the normal opening maneuver, when trying to violate the closure by pushing directly on the front of the latch (13), the first thing that happens is that the turntable (24) swings hiding inside the latch (13) and making its dorsal appendix (24a) face said first projection (25), so that it constitutes a stop which prevents the retraction of the latch (13).

Also according to the invention there are lateral closing points, or lateral forwarding (27), comprising (figures 23 to 26) a forwarding box (27a), a rotary latch (13) provided with rotating plate (24) with appendix dorsal (24a), a first vertical sliding ruler (28) that is on track between the bottom and side walls of the forwarding box (27a) and a second disk (29); The first sliding vertical ruler (28) has means at both ends for attachment to a fault (14), it has a side wall (28a) provided with a pair of protruding buttons (28b, 28c) located in opposite diametral positions with respect to the rotation. of the second disk (29), and has a second projection (30) capable of constituting a stop for the dorsal appendix (24a) of the turntable (24) housed in the rotary latch (13); The second disk (29) is installed on a pivot shaft (38) that has sliding adjustment on a sliding vertical (28d) of the lateral wall (28a) of the sliding first vertical ruler (28), this second disk (29) has a pair of radial recesses (29a) in diametral opposition and which, in a state of rest or closed lock, are applied laterally on said buttons (28b, 28c) in reverse, one above and the other below, and in this second disk (29) is a prominence (29b) that in said resting state is applied below the tail (13a) of the rotary latch (13). Starting from the resting position shown in Figure 24, when pulling the first vertical ruler (28) to the right, the button (28b) pushes on the corresponding radial recess (29a) and the second disc (29) rotates causing its prominence (29b) drives on the tail (13a) of the latch (13) causing it to retract; in this maneuver the other Radial incoming (29a) is separated from the other button (28c). When the first vertical ruler (28) is pulled to the left (figure 26), the same maneuver takes place, but the other button (28c) is now active. This evidences the reversibility of the mechanism. There are also (figures 29 and 30) upper and lower closing points, or vertical forwarding (33), comprising a forwarding box (33a), a rotary latch (13) provided with a rotating plate (24) with dorsal appendix (24a ), a second vertical sliding rule (34) that is on track between the bottom and side walls of the forwarding box (33a) and a rotating square (35); The second vertical sliding rule (34) has rear means for joining it to a fault (14), it is capable of sliding between respective upper and lower positions that are coincident with those of the extended and retracted rotary latch (13), and this second vertical sliding rule (34) has a side wall (34a) provided with a fin (34b); The rotary square (35) operates in a vertical plane and has a first branch (35a) applied under the tail (13a) of the rotary latch (13) and a second branch (35b) which, with respect to the opening stroke of the second vertical sliding rule (34), is applied in front of the fin (34b) formed in the side wall (34a) of this second vertical sliding rule (34). Starting (figure 29) from the resting position, when pulling the second vertical sliding ruler (34), the fin (34b) pushes on the second branch (35b) of the rotating square (35), with which it rotates and its first branch (35a) pushes on the tail (13a) of the latch (13) and it retracts (figure 30).

Another peculiarity of the invention is that (figures 27 and 28) the fault (14) has a "C" profile that forms a straight-walled slide inside it along which a tablet (31) has sliding adjustment that with turning capacity is installed in an anchor (32) tied to the door (4). With this device the assembly and alignment of the failure (14) is facilitated.
