Description

Modular panic closure device reversible and versatile.

Field of the Invention

This invention relates to a device of modular conception that has a reversible character and can be Multi-purpose operated, which is applicable to closures panic that are installed in emergency exit doors and that have a main lock mechanism, with or without latch of closing, and / or upper closing points (on the lintel) and lower (above the threshold), and / or lateral closing points on the frame amount, whose main lock is operated by a bar that is installed transversely on the door.

Prior art

In this field they are known and employed Usually two types of panic bar. One of them consists on a rotating bar that, by means of connecting rods, is articulated at its ends to make a knock on the door; East guy is known in this field by his name in English, "pushbar" that will be used in the future. The other type consists in a bar that incorporates an outer casing with the ability to linear movement perpendicular to the door; this guy is known in this field by its name in English, "touchbar" which will be the used onwards.

The current situation is that there are two different concepts of panic bar (pushbar and touchbar) and, Within each of them, there are all variants before targeted: a main lock that has a latch or lacks of the; that the main lock must also activate some lateral forwarding at different height of the door; that since the main lock must also be operated upper and lower forwarding.

Well, today each of these options responds to an own and exclusive design; in a way that Manufacturers and the distribution chain of this kind of product They support big design problems, provisioning of materials, production, storage and distribution.

Explanation of 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 execution variants existing today, previously reviewed.

To this end, the proposed device comprises a main lock in which a chain is installed Compact modular kinematics that, taking as a positional reference the operational status of the main door lock, consists of an upper angled lever, a lower angled lever, a first disk, a rotating shaft, vertical and sliding top plate and bottom plate; the upper bent levers e lower are in a vertical plane and transverse to the door, with its concave or interior angle facing the door, are articulated in its elbow in symmetrical places with respect to the axis rotary, are likely to swing between positions closed and open the lock and have two first arms and second arms, the first arms extend aerially to the mutual encounter and their ends overlap in an extreme part where the first arm of the second lever has a first stud with sliding adjustment through a torn opening of the first arm of the first lever, and the second arms extend transversely to the door and at its end are articulated in turn relative to respective first pin and second pin that they have their ends with sliding adjustment in vertical grooves of the main lock box that are parallel to the door and that their extreme positions are consistent with the positions closed and open lock; the first disc is between a of the angled levers and a side wall of the box lock, and has a second stud that is applied against the inner edge of one of the angled levers, whose first disc It is capable of reversible mounting on the rotating shaft in two diametrically opposite positions; vertical sliding plate upper and lower vertical sliding plate are parallel to the door, are guided laterally in the lock box, are superimposed on each other, one of them attached to the floor of the box lock, and each of them forms a pair of collateral lace in which a respective one of said first pin is coupled and second pin, whose upper vertical plate and vertical plate lower are likely to slide between paths extended and retracted, relative to the center of the lock box, which are respectively coincident with said positions of closed lock and open lock. In this constitution complies that, on the part towards the closing frame and through the torn opening of the first arm of the first lever, the first busty protrudes in a part that is applied under a tail of a rotary latch that is likely to swing between extended and retracted positions such that, in the position extended, this protruding part of the first stud, and therefore the first arms and the transverse stud of the first disc are in its closest position to the door, the first pin and the second pin are at the ends of their respective grooves verticals that are further apart from each other, the vertical plate upper and lower vertical plate are with each other in the further positions, and in the retracted position, this part protruding from the first busty, and therefore the first arms the transverse bumper of the first disc are in its furthest position of the door, the first pin and the second pin are in the ends of their respective vertical slots that are more next to each other, the upper vertical plate and the vertical plate Lower are each other in the closest positions.

This kinematic chain behaves so that, when the first arm of any one of the angled levers it is driven from the rest or lock position closed, this angled lever rotates and drags the first arm of the another lever angled symmetrically. This turn of the levers Layered is used so that, through the first pin and the second pin, the second arms of the same drive the vertical sliding of said upper and lower plates which, according to the invention have means for joining with fallebas that they operate on forwarding that establish superior closing points and lower, and / or lateral closing points other than the main lock; whereupon, the position of opening in these forwardings. At the same time, if the lock main is equipped with rotary doorknob, it will be retracted to the opening position under the impulse that exerts on its tail the  protruding part of the first stud belonging to the first arm of the lower angled lever.

The rotation of the first arms of the levers Layered can be achieved in various ways. One of these consists in which the rotating shaft is coupled with the corresponding connecting rod of a pushbar. Then, when you push the pushbar, the connecting rod rotates and spins the rotating shaft on which the first disc is keyed, and the second stud of this first album is the one 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 opposed, so, depending on what this position, the second stud will push on the first arm of the upper angled lever or on the lower angled lever; This means that the same mechanism can be used to indistinct mode for right doors and left doors, with Just turn it over. 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 Consider two options. A preferred option consists of existence of a "Y" shaped rocker that extends in horizontal with its convex angle in opposition to the door, which operates along a plane transverse to the door with its articulated foot on a support attached to it and at its end towards the main lock has two nails that are applied under the lower edge of the first arms of the angled levers, when time that at its opposite end to the nails this rocker is articulated to the mobile external cover of a touchbar. By pressing on this touchbar cover, the rocker is rotated within the two quadrants farthest from the door and nails of the same are those that exert the drive that in the case of the Pushbar was entrusted to the second stud of the first disc. Is say, the same kinematic chain based on the levers Layered is applicable for a touchbar, with or without latch, and reversible mode

Another application option for a touchbar is that a python protrudes in the upper vertical plate which, in the vertical direction, has a tooth applied laterally which belongs to a rotary 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 turning is attached to a brace that extends horizontally and parallel to the door and that is pushed into the main lock when the external mobile cover of a touchbar, strap that moves in length such a stroke that drives the rotation of the lever rotary so that it produces a linear path of the tooth which is equal to the operating displacement of said sliding plate upper between their respective closed lock positions and open lock. This solution is applicable for touchbar that respond to a more traditional concept in which when you press your mobile deck spins compasses that operate in both quadrants closest to the door; this turn becomes a longitudinal impulse of the tie which is now used to rotate the rotary lever which, with its tooth, pushes the python of the lower sliding vertical plate so that, through of the second pin that is coupled with the second arm of the Lower angled lever, make the latter rotate by dragging I get the upper angled lever which, in turn, by its second arm coupled with the first pin, will produce the sliding of the upper vertical plate in the opposite direction to that of the lower vertical plate.

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

Another feature of the invention consists in that the rotary latch incorporates a rotating plate inside of vertical axis that, inside the lock box and hovering by behind the rotary latch, it presents a dorsal appendix; with relationship to the position of extended rotary latch, or of main lock closed, the turntable is able to swing between two positions, a position that is driven by a spring and in which an arched front edge itself appears with respect to the plane of the rotary latch that attacks your strike in the frame of the door while the back appendix is deviated from of a first protrusion formed in the upper sliding plate, and another position in which said arched front edge of the plate swivel is retracted within the rotary latch and the dorsal appendix is in front and next to the first projection; and with relationship to the state of retracted rotary latch, or lock main open, arched front edge of turntable  is adjacent to the edge of the latch actuation window Rotary This mechanism provides security against attempts to violate the closure by the method of influencing the attack front of the latch with the edge of a credit card  or similar inserted by the slot between the door and the frame; when you try such a thing, the edge of the card affects first against the turntable, which tilts and opposes its dorsal appendix to the first projection of the lower vertical plate, with what remains latch retraction prevented; when the retraction of latch is produced by the action of the kinematic chain in the normal opening maneuver, dorsal appendix free position of the first projection.

Another peculiarity of the invention is that there are lateral closure points, or lateral forwarding, which they comprise a forwarding box, a rotary latch provided with turntable with dorsal appendix, a first vertical ruler sliding that is on track between the back walls and sides of the forwarding box and a second disk; the first vertical sliding ruler has means at both ends for its union to a failure, it has a side wall provided with a pair of protruding buttons sitos in opposite diametral positions with respect to of the spin of the second disc, and has a second susceptible projection to constitute a stop for the dorsal appendix of the turntable housed in the rotary latch; the second disk is installed on a pivot shaft that has sliding adjustment on a vertical Sliding side wall of the sliding first ruler vertical, this second disc has a pair of radial entrances in diametral opposition and that, in a state of rest or lock closed, they are applied laterally on said buttons inverse way, one above and the other below, and in this second disc there is a prominence that in that state of rest is applied below the tail of the rotary latch. When, through a failure, the first vertical rule is displaced in one direction, the button that in that sense is applied against a radial entrant pushes on it and turns the second disk, which with its prominence drives on the tail of the latch causing it to retract. Note that this solution  It is also reversible.

Another peculiarity of the invention is that there are upper and lower closing points, or forwarding vertical, comprising a forwarding box, a latch Rotary equipped with turntable with dorsal appendix, a second vertical sliding rule that is on track between the bottom and side walls of the forwarding box and a square rotary; the second vertical sliding rule has means rear to join a failure, is likely to slide between respective upper and lower positions that are coinciding with those of extended and retracted rotary latch, and this second vertical sliding ruler has a side wall provided with a fin; the rotary squad operates on a plane vertical and has a first branch applied under the tail of the latch rotary and a second branch that, with respect to the career of opening of the second vertical sliding rule, is applied ahead of the fin formed on the side wall of this second vertical slide rule. When the latch is extended in your closed position and, by failing, the second is pulled vertical sliding ruler, the flap of its side wall drives the second branch of the rotary squad and, when turning this, its first branch lifts the tail of the latch causing retraction of East. Since, as is evident, the vertical displacement of 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 forwarding is valid either for top closure or for closure lower; that is, it is reversible.

Another feature of the invention is that the I had a "C" profile that forms a sliding straight walls along which it has adjustment sliding a pickup that with turning capacity is installed in An anchor tied to the door. This solution enables a turn of he failed her about her anchor tied at the door, facilitating the placement and the same and its correct alignment, compensating eventual assembly planning errors.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, referred to a device modular reversible and versatile panic closure, of the closures that are installed on emergency exit doors and that they have a main lock mechanism, with or without latch closing, and / or upper (over the lintel) and lower closing points (above the threshold), and / or lateral closing points on the upright of the frame, whose main lock is operated by a bar which is installed transverse on the door, either a bar swivel which, by means of connecting rods, is articulated in its ends to make a knock on the door (hereinafter, "pushbar", by its name in English) or by a bar that incorporates an outer shell with linear movement capability perpendicular to the door (hereinafter, "touchbar", for its Name in english).

As Figure 1 illustrates, the device according to the invention comprises a main lock (1) in which it is installed a compact modular kinematic chain that, taking as positional reference the operative situation of the lock main (1) on the door (4), consists of an upper angled lever (2), a lower angled lever (3), a first disc (5), a shaft rotary (6), vertical and sliding top plate (7) and bottom plate (8); the upper (2) and lower cranked levers (3) are in a vertical plane and transverse to the door (4), with its  concave or interior angle facing the door (4), are articulated in its elbow in symmetrical places with respect to the axis rotary (6), are likely to swing between positions closed and open the lock (1) and have two first arms (2a, 3a) and second arms (2b, 3b), the first arms (2nd, 3rd) extend aerially to the mutual encounter and its ends they overlap at an extreme part where the first arm (3a) of the second lever (3) has a first pin (3c) that with adjustment Sliding through a torn opening (2c) of the first arm (2a) of the first lever (2), and the second arms (2b, 3b) are extend transversely to the door (4) and at its end are articulated in rotation with respect to respective first pin (9) and second pin (10) that have their ends with sliding adjustment in vertical slots (11) of the lock box (1a) main (1) that are parallel to the door (4) and that their extreme positions are consistent with closed positions and open the lock (1); the first disc (5) is between one of the angled levers (2, 3) and a side wall of the box lock (1a), and has a second stud (12) that is applied against the inside edge of one of the angled levers (2, 3), whose first disc (5) is capable of reversible mounting on the rotary axis (6) in two diametrically opposite positions; the vertical top sliding plate (7) and vertical plate bottom slide (8) are parallel to the door (4), are guided laterally in the lock box (1a), they are superimposed on each other, one of them attached to the floor of the box lock (1a), and each of them forms a pair of collaterals lace (7a, 8a) in which a respective one of said couplings is coupled first pin (9) and second pin (10), whose vertical plate upper (7) and lower vertical plate (8) are susceptible to slide between paths extended and retracted, relative to center of the lock box (1a), which are respectively coinciding with said closed lock positions (1) and of lock (1) open. The upper vertical plate (7) and the plate lower vertical (8) have connection means with fallebas (14) that they operate on forwarding that will be explained in detail later and that establish upper and lower closing points (see figures 29 and 30), and / or lateral closure points other than that of the main lock (1) (figures 23 to 26). It is very frequent incorporation of a latch in the main lock (1), so that, according to the invention for this purpose, it is fulfilled that, by the part towards the closing frame and through the torn opening (2c) of the first arm (2a) of the first lever (2), the first busty (3c) protrudes in a part that is applied under a tail (13a) of a rotary latch (13) that is susceptible to tilting between extended and retracted positions 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 in the ends of their respective vertical grooves (11) that are more away from each other, the upper vertical plate (7) and the plate lower vertical (8) are each other in the most positions away, and in the retracted position, this protruding part of the first stud (3c), and therefore the first arms (2nd, 3rd) and the transverse stud (12) of the first disc (5) are in position furthest from the door (4), the first pin (9) and the second pin (10) are at the ends of their respective grooves vertical (11) that are closer to each other, the vertical plate upper (7) and the lower vertical plate (8) are with each other in the nearest positions.

The described device constitutes a chain kinematics of great constitutive and functional simplicity that, as has been exposed above and will look in detail from now on, it will be a base module to apply it interchangeably for bars anti-panic pushbar or touchbar, reversible and which is capable of being operated by various driving means. Its operation is based on the mutual coupling of the levers upper (2) and lower (3) bends, by which they make a turn matched in opposite directions whatever the driving medium employee and whatever the arm of the same on which Apply the impulse.

In the case of a pushbar (figures 8 to 11) the connecting rod (15) thereof will be mounted on the rotary shaft (6) of so that, when activated, the rotation of the latter makes the second pin (12) of the first disc (5) push up (in the figure 8) on the first arm (2a) of the upper bent lever (2); through the mutual coupling established by the first stud (3c) (figure 9) the lower angled 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 sliding plates (7) e lower (8), 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) forwarding movements of these plates (7 and 8) will be transmitted to them through the fallebas (14); if this main lock (1) incorporates a latch  rotary (13) (as considered in figure 1), in this maneuver  described will be retracted by the thrust that on its tail (13a) exerts said first stud (3c). The reversibility is obtained mounting the first disc (5) in diametrically opposite position, as illustrated in figure 11.

For the application of the recommended device to A touchbar bar 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 transverse plane to the door (4) with its foot articulated in a support (18) attached to it and at its end towards the main lock (1) has two nails (17) that are applied under the lower edge of the first arms (2nd, 3rd) of the angled levers (2, 3), while at its opposite end to the nails (17) this rocker is articulated to the outer mobile cover of a touchbar. For its shape and assembly, as can be seen in the figures, this rocker (16) swings in the two quadrants that they are further away from the door (4). When the touchbar pressing on its mobile cover, the rocker (16) located in the rest 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 turn 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 that a python (19) protrudes in the upper vertical plate (7) which, in the vertical direction, a tooth is applied laterally (21) which belongs to a rotary lever (20) that 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 turning is attached to a tie rod (23) that extends horizontally and parallel to the door (4) and that is pushed towards the main lock (1) when the mobile outer cover of a touchbar is pressed, strap (23) that travels in length a run such that drives the rotation of the rotary lever (20) so that produces a linear path of the tooth (21) that is equal to operational displacement of said upper sliding plate (7) between their respective closed lock and lock positions open Starting from the resting position (figure 16), at press on the mobile cover of the touchbar the mechanism internal produces traction on the strap (23) that rotates the rotary lever (20) so that the tooth (21) of this thrust on the python (19) and cause the plate to move lower vertical (8); then drag the second pin with you (10) by tilting the lower angled lever (3) which, at its once, drag the upper angled lever (2), which through the first pin (9) makes the upper vertical plate (7) slide in the opposite direction than the vertical plate lower (8), while the first pin (3c) of the lever upper bent (2) drives on the tail (13a) of the latch rotary (13) so that it retracts (figure 17).

To establish security against cited attempts to breach the closure by the classic method of the credit card the rotary latch (13) incorporates (figures 18 to 22) inside it a turntable (24) of vertical axis which, inside the lock box (1a) and peeking out from behind the rotary latch (13), has a dorsal appendix (24a); with in relation to the extended rotary latch position (13), or of main lock (1) closed, the turntable (24) is capable from oscillating between two positions, a position that is driven by a spring (26) and in which an arched front edge itself peeks from the plane of the rotary latch (13) that attacks its strike on the door frame (4) while the appendix dorsal (24a) is deviated from a first projection (25) formed in the upper sliding plate (7), and another position in the that said arched front edge of the turntable (24) is retracted within the rotary latch (13) and the appendix dorsal (24a) is in front and next to the first projection (25); and with in relation to the state of retracted latch (13) retracted, or of main lock (1) open, the arched front edge of the turntable (24) is adjacent to the edge of the window actuation of the rotary latch (13). In 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 upper sliding vertical plate (7); without However, outside the normal opening maneuver, when trying to violate the closure by pushing directly on the front of latch attack (13), the first thing that happens is that the plate swivel (24) swings hiding inside the latch (13) and causing its dorsal appendix (24a) to face said first projection (25), which constitutes a stop that prevents latch retraction (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 rotating latch (13) provided with turntable (24) with dorsal appendix (24a), a first sliding vertical ruler (28) that is on track between the bottom and side walls of the forwarding box (27a) and a second disk (29); the first vertical sliding ruler (28) it has means at both ends for its union to a failure (14), it has a side wall (28a) provided with a pair of projections buttons (28b, 28c) located in opposite diametral positions regarding the rotation of the second disc (29), and has a second overhang (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) which has sliding adjustment on a vertical slide (28d) of the side wall (28a) of the sliding first vertical ruler (28), this second disc (29) has a pair of radial recesses (29a) in  diametral opposition and that, in a state of rest or lock closed, they are applied laterally on said buttons (28b, 28c) inversely, one above and the other below, and in this second disc (29) there 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 to the right of the first vertical ruler (28), the button (28b) pushes on the radial inlet (29a) corresponding and the second disc (29) rotates making its prominence (29b) push onto tail (13a) of latch (13) causing it to retract; in this maneuver the other entrant radial (29a) is separated from the other button (28c). When you pull the first vertical ruler (28) to the left (figure 26), the same maneuver, but the other button (28c) is now active. This evidence the reversibility of the mechanism.
