Description

Adjustable interlocking points in panic or emergency closure devices.

Field of the Invention

This invention concerns some points of interlocking adjustable in panic closing devices or emergency, that is, those in emergency situations are open from the inside without a key, to facilitate The escape of people.

In particular, the invention contemplates two high (high point) and low (low point) interlocking points for Forwarding installed on the normally fixed sheet (which is only open in case of urgent evacuation of people) from a double door emergency door than on your other sheet normally swinging (which is used for regular traffic) is equipped with an anti-panic push bar that acts as an opening from the inside the premises by simple pressure exerted on it, in where the fixed blade on its inner side incorporates a set of rods, upper and lower, which at their ends have means of known closure in relation to the high and low points, and that, between their interlocking and release positions, these upper and lower rods are operated by any means itself known.

Prior art

In this field it is normal that at the time of install the fixed sheet appreciate the existence of wide streets excessive between the upper and lower edges of it and the respective lintel and threshold of the double leaf door frame; in such a way that this width can exceed or cancel a large part of the path that is capable of providing the drive mechanism of the rods, which could not lead to closure at high and low points, or to occur in a way precarious

This requires that there are some means of regulation that can be operated on site by the installer. When, as is the case, the rod device and its resends are internal to the fixed blade body, it is very necessary that the given solution be simple, robust and reliable, since its disassembly by breakage or malfunction is expensive and slow; In addition, it must be easy to operate from the outside, which implies greater difficulty in designing a good solution in this regard.

Explanation of the invention and advantages

\hbox{es coaxial con,  respectivamente, el paso circular ancho
y el paso circular  estrecho.}

Faced with this state of affairs, this invention advocates a solution consisting in that, at the high point, the upper rod has an upper terminal coupled which at its end is screwed into a threaded bushing that has a groove for a screwed tool. and in which, above this end of the terminal, a python is also screwed that has a fingerprint for its rotary drive which are accessible through the upper mouth of the bushing which, in turn, is accessible through the frame of the known closing means and associated with this high point; and because, at the low point, the lower rod has associated a device comprising: a lower terminal, a chassis, a cylindrical latch, a horizontal push button and two horizontal springs; the lower terminal is coupled to the end of the lower rod and has an annular throat; said chassis forms horizontal wings, upper and lower wings, and a vertical side, in the upper wing there is a recess in which the annular throat of the lower terminal is coupled, in the lower wing there is a circular hole and the vertical side is adjacent to the wall of the fixed leaf and has a window facing a hole of this wall of the fixed leaf; said latch has rotating coupling means with the lower terminal and has annular channels that are spaced regularly; said horizontal pushbutton is conveniently smaller than the width of said annular channels of the latch and rests on the lower wing of the chassis, where it has a composite perforation that is formed by a wide circular passage that links with a narrow circular passage, the wide passage It has a sliding adjustment with the latch and the narrow passage has its diameter adjusted by excess in relation to the bottom of the annular channels of the latch itself, whose horizontal push-button is likely to move between two positions in which the centers of the wide circular passages and narrow are coaxial with the latch; said horizontal springs operate between the horizontal pushbutton and a vertical wall that is parallel to the vertical side and that belongs to a chassis supplement, whose springs operate between two states of relaxation and tension in which the horizontal pushbutton

 \ hbox {is coaxial with, respectively, the wide circular pitch
and the narrow circular passage.} 

According to this proposed constitution, the Regulation at these high and low points is simple and fast. At high point, and above the upper edge of the fixed blade, it rotate the threaded bushing by twisting it into the terminal longer until the joint length of the upper rod and this terminal, in conjunction with the path operating the rod and with the width of the street between said upper edge of the fixed leaf and its lintel; finally, it acts on the footprint to the effect of the threaded python by twisting it until butt against the end of the upper terminal, so that this Python performs the function of locknut that maintains the position reliably regulated.

At the low point the presence of the soil of the enclosure prevents work from the bottom edge of the fixed blade. The invention gives a solution to the effect: in the relaxed state of springs any one of the annular channels of the latch is coupled by lace at the edge of the narrow annular passage of the button; through the hole in the leaf wall fixed push this horizontal button pushing the springs to its state of tension in which the edge of the narrow circular passage has left the channel of the latch and this is coaxial with the step wide circular, through which it can pass freely; when releasing the button the hitch occurs again in the circular passage narrow with respect to another annular channel of the latch according to which one the new longitudinal position of the latch chosen as the point suitable regulation.

Another feature of the invention consists in that said coupling means between the lower terminal and the latch are that the bottom terminal forms a flat tang diametral that fits in a latch box. For the guidance of latch according to the invention, there is, on the one hand, a first guide sleeve that its internal diameter has adjustment sliding with respect to the latch and which is fitted in said chassis hole; on the other hand, in relation to singing bottom of the fixed blade, there is a guiding device of the latch consisting of: a bottom plate orified with clearance with respect to the diameter of the latch and tied to the edge bottom of the fixed blade; a square that its horizontal branch is fixed to the bottom plate and orified in correspondence with it, and that its vertical branch is attached to the outer side of the side vertical of the chassis and is provided with a drill interposed between the window of this vertical side and the hole of said sheet fixed; and a second guide sleeve that is coupled through the holes of said lower plate and horizontal wing of the squad.

In particular it is about two points high interlock (high point) and low (low point) for forwarding  installed on the normally fixed sheet (1) of a door double sheet emergency than on your other normally swinging sheet (2) is equipped with a panic pushbutton bar (3) that acts on the opening from inside the premises by simple pressure exerted on it; where, the fixed sheet (1), on its inner side, incorporates a set of rods, upper (4) and lower (5), than in its ends have known closure means in relation to with the high and low points, and that, between their positions of interlocking and release, these upper and lower rods are acted by any means known per se.

Thus, according to the invention, at said high point, the upper rod (4) has an upper terminal coupled (6) than in its end is screwed inside a threaded bushing (7) which has a groove (7a) for a bolting tool and in which, above this end of the terminal (6), also Screw a python (8) that has a fingerprint (9) to drive swivel that is accessible through the upper mouth of said bush (7) which, in turn, is accessible through the frame (10) of the closing means known and associated with this high point; Y, at said low point, the lower rod (5) has an associated device comprising: a lower terminal (11), a chassis (12), a cylindrical latch (13), a horizontal button (14) and two horizontal springs (15); the lower terminal (11) is coupled to the end of the lower rod (5) and has a throat to annul (16); said chassis (12) forms horizontal wings, upper (17) and lower (18), and a vertical side (19), on the wing  upper (17) there is an inlet (20) in which the annular throat (16) of the lower terminal (11), in the lower wing (18) there is a circular hole (21) and the vertical side (19) is adjacent to the wall of the fixed sheet (1) and has a window (22) facing a hole (23) of this fixed leaf wall (1); said latch (13) has rotating coupling means with the lower terminal (11) and has annular channels (24) that are regularly spaced; said horizontal button (14) is of thickness conveniently less than the width of said channels annular (24) of the latch and rest on the lower wing (18) of the chassis (12), where it has a compound perforation (25-26) which is formed by a wide circular passage (25) that links with a narrow circular passage (26), the wide passage (25) has sliding adjustment with the latch (13) and the pitch narrow (26) has its diameter adjusted by excess in relation to the from the bottom of the annular channels (24) of the latch itself (13), whose horizontal button (14) is capable of moving between two positions in which the centers of the wide circular passages (25) and narrow (26) are coaxial with the latch (13); sayings Horizontal springs (15) operate between the horizontal button (14) and a vertical wall (28) that is parallel to the vertical side (19) and which belongs to a supplement (27) of the chassis (12), whose springs  (15) operate between two states of relaxation and tension in the that the horizontal button (14) is coaxial with, respectively, the wide circular passage (25) and narrow circular passage (26).

As for the high point, Figures 2 and 3 illustrate the joint assembly of the upper terminal (6), the threaded bushing (7) and the threaded python (8); as well as clearly expose the groove (7a) of the threaded bushing (7) and the footprint (9) of the threaded python (8). In accordance with all this, the adjustment maneuver at the high point is very simple: first, acting on the slit (7a) the bushing (7) is screwed in relation to the upper terminal (6) in the measure chosen to achieve that the length upper terminal assembly (6) and upper rod (4) be desired; second and last, through the mouth of the threaded bushing (7) the threaded python (8) is screwed until it stops against the end of this upper terminal (6), so that it operates as a locknut that reliably maintains the regulation
established.

Regarding the low point, figures 4 to 9 show views that are defining the means proposed to effect the regulation of the joint length of the lower rod (5) and the latch (13) coupled to the end thereof. To carry out this regulation, the maneuver is the one described below and illustrated by figures 11 to 14. The resting position is shown in figures 1, 13 and 14, where the springs (15) are in its relaxed state and the edge of the narrow circular passage (26) is inserted in one of the several annular channels (24) of the latch (13), whereby it is immobilized in its longitudinal direction; starting from this situation, through the hole (23) of the wall of the fixed leaf (1) and the window (22) of the vertical side (19) of the chassis (12), it is pushed on the button (14) and , when the springs (15) are compressed, the latch (13) is achieved in a coaxial position with the wide circular passage (25) and can thus be moved (figures 11 and 12) through this wide circular passage (25) to choose which of the several annular channels (24) thereof must be coupled in the narrow circular passage (26) once the push on the push button (14) is stopped and the springs (15) recover their state
relaxed.
