Description

The invention relates to an anti-panic locking system mentioned in the preamble of claim 1. Such System is known from EP 481 931.

Such an anti-panic locking system has a push rod on that as the longitudinal, transverse and vertical directions respective directions that are along the width, the strength and extend the height of a door, and as front and rear Ends defines the ends that the closing edge of the door are closest to or away from it. The push rod is attached lengthwise to the back of the door and consists of a fixed half-bar, which is attached to the door and a movable half-bar, preferably inside the fixed push rod, is movable. The moveable Push rod calls across when pressed down Angle lever produces a longitudinal movement of a pull rod and drives about this the retraction of a main bar, which with the Push rod is aligned lengthways, and retracting vertical upper and lower output elements that Pull back the corresponding upper and lower auxiliary latches a closure on the lintel and on the threshold of the corresponding Cause door frame.

This type of locking system is used according to the regulations all escape routes and emergency exits from public places (Business centers, ballrooms, sports stadiums ...), office buildings, Industrial buildings etc. installed, which ultimately means in all Cases in which after a panic and / or emergency situation large number of people must escape at the same time.

The currently known systems in this field do not result in any Stop, the pressure stroke when depressing the movable Half bar is limited to the dimension (including a certain security area) to achieve the Withdrawal of the latch is required. In many cases (Ballrooms, sports facilities ...) is the treatment of the locking system very careless and even brutal, which leads to the fact that the push rod to the end then another pulling force exercises when the bolts are already withdrawn, and this tractive force causes the transmission mechanism (the on most sensitive and expensive) is often excessive Is exposed to forces.

On the other hand, such anti-panic locking systems are both to operate in the door as well as on this built or external locks used.

A mechanism is known for built-in locks, which in includes an outline area that is substantially the same the general outline of the pushrod, which is extends in the longitudinal direction across the width of the door. This Mechanism uses the longitudinal movement of the pull rod for actuation a transmission gear with a transversely extending output shaft, which is the nut of the built-in Actuated lock.

On the other hand, there is a solution for the built locks ES-A1 9002589 known, in which the operated by the pull rod Mechanism in a large case with an overturned "T" shape is arranged, the wings formed by the crossbar (which are arranged vertically) the upper and lower output elements record the auxiliary bolts via respective rods actuate.

This diversity of configurations complicates the Manufacture of such locking systems and their distribution and installation.

In this type of locking system there are lids or covers known, which are arranged in an actuation module unit, which has recesses for one or more locking points, such that when the head of the actuator module is not used for a locking point, the upper and lower locking points can be hidden while if the actuation module unit for two locking points (upper and lower closure point) is used, these recesses open are, while the locking point of the main bolt is covered, this requires one or two different lids.

The invention is based on the object of an anti-panic locking system to create the type mentioned at the beginning versatility and compact structure an increased Strength and resilience even with rough treatment having.

This object is achieved by the features specified in claim 1 solved.

Advantageous refinements and developments of the invention result from the subclaims.

A preferred feature of the invention is that each angle lever operated by the movable half bar in Transversal direction around his on the fixed half-bar Vertex pivotable and with first and second arms is provided with the movable half-bar or the Lock mechanism actuating tie rod are connected, wherein the first arm has a special shape, which is characterized by a protruding lower edge and one directed towards the apex slot-shaped opening is formed. The projecting Ridge comes against a bottom of the solid half bar just then to the system when the movable half-bar to the end point of an operating stroke was depressed, the main and Auxiliary bolt their retracted positions at this end point have reached and the slot-shaped opening sliding by one vertical bolt was passed through, into an upper flange plate is inserted, which is attached to the movable half-bar is. The swivel attachment of the vertices of the Angle lever is raised in a lower flange plate, which is attached to the fixed half-bar. Here is the operating stroke of depressing the movable half-bar to fully retract the latches smaller than that possible stroke of this half bar.

This solution results in a system resilience in the sense that a mechanical stop by the projecting Edge is caused, which prevents the tie rod pulls on the opening mechanisms after the latches have been withdrawn.

In this regard, there is another peculiarity of the invention in that the protruding edge at their installation against the bottom of the fixed half-bar in the transverse direction with the Starting and ending positions of the bolt is aligned. hereby is achieved that the resistance with the force is aligned, which is exerted on the push rod. On in this way the robustness of the locking system is promoted.

A preferred feature of the invention is that Structure of the actuation module unit in a cross section 5 is included, which is substantially equal to that of the push rod is. In this cross-section is a device in a compact manner attached to the longitudinal force of the tie rod receives and converts this into a driving force that the Main latch and the upper and lower output elements retracts. This device includes a graduated pull mechanism, which is displaceable in the longitudinal direction Transmission part is formed, which simultaneously with a first and a second slider, which is coupled at the front end articulated with a rear pin of the main bolt 5 is. The main bolt can have a locking swivel lever inside included that by pulling back the latch direct influence on the tip prevented. The coupling with the first slide takes place via an adjustable mechanical Game or a delay that consists in that at push rod not depressed on the first slide attached cross bolt at a selectively changeable point in a longitudinal guideway of the transmission part is arranged, during the coupling of the transmission part with the second Slider over a transverse approach of the transmission part takes place, which crosses a longitudinal groove of the second slide and can come to rest against the rear end of this longitudinal groove.

This construction divided the graduated pull mechanism the pressure actuation stroke of the push rod in two partial strokes: a first idle stroke, which is formed in that the cross bolt of the first slide the rear end of the longitudinal guideway of the transmission part must reach, whereby this there is no retraction on the bars, and a second Working stroke in which the cross bolt pulls on the exerts second slide and pulls back the latch.

Withdrawal of the main bar is made directly by the second Slider caused. On the other hand, the withdrawal takes place the auxiliary bolt in an independent way, if at the same time, in that the transmission part is articulated with one in Transversely extending pivot pin is coupled, the is eccentrically attached to a rotatable drive plate, the one with two radial, diametrically opposite slots is provided, in which respective transverse pins slide, that of the respective upper and lower output elements go out, the corresponding connectors for each Have actuating rods of the auxiliary bolts. The output elements have respective inclined guideways, in which slide first and second bolts, respectively, of respective rotatable first and second plates that are coaxial with the drive plate, and those like this are free are rotatable relative to the axis of a nut by a external handle is operated, which is held on a plate which is attached externally to the bottom of the actuation module unit is. The retraction movement of the transfer part results in one Traction on the eccentric pivot pin of the drive plate such that it rotates and the effect of its radial grooves on the transverse tenons of the vertical Output elements drives them to pull back the auxiliary bolts.

The division of these strokes enables adjustment of the Amplitude of these strokes to adapt the device to bars, that require different retraction strokes, as well as for one any application to attached or built-in locks, which require different movements of the drawbar.

Another important advantage of this new construction is the compact form of the actuation module unit, which at attached locks which require a lot of space Unit with tilted "T" shape replaced according to ES-A1 9002589, and which simply include the engaging mechanism can be used for the operation of built-in locks is, this novel actuator module unit easily can be attached to any end of the drawbar and thus in a reversible way to adapt to the different Arrangements of emergency doors is applicable.

In the accompanying drawings is a preferred embodiment an anti-panic locking system shown, the (Figure 1) Compression rod (1), as the longitudinal direction, transverse direction and vertical direction respective directions that are along the Width, the thickness or the height of a door (2), and front and rear ends defined by the closing edge of the Door closest to or away from it. This Push rod (1) is in the longitudinal direction on the back of the door (2) attached and consists of an attached to this door (2) fixed half-bar (1a), opposite which a movable half-bar (1b) is displaceable in the transverse direction when depressed a longitudinal movement via the respective angle lever (3) ar pull rod (4) causes and pulling back over this a main bolt (5) aligned with the push rod (1) and from respective vertical upper (6) and lower (7) Output elements drives the corresponding upper (8) and Pull back the lower (9) auxiliary latch, which closes the Cause or fall on the threshold of the respective door frame.

An essential feature of the invention consists in (FIG. 2 to 4) that each angle lever (3) in the transverse direction around its vertex articulated on the fixed half-bar (1a) pivotable and provided with first (3a) and second (3b) arms is that with the movable half-bar (1b) or Drawbar (4) are connected. The first arm (3a) has one special shape, which is characterized by a projecting lower edge (33) and a slit-shaped opening facing the apex (34) is formed.

The projecting edge (33) can rest against a floor the fixed half-bar (1a) just when the movable Half bar (1b) to the end point of an operating stroke was depressed on the main latch (5) and the auxiliary latch (8,9) have reached their retracted position. In the slot-shaped opening (34) was through this position a vertical bolt (35) slidably traverses in a Upper flange plate (36) is arranged on the movable Half bar (1b) is attached. The articulated attachment of the The apex of the angle lever (3) is raised in a lower one Flange plate (37) held on the fixed half-bar (1a) is attached. In this regard, Figure 2 shows a solution, at the bottom of the fixed half-bar (1a) through this lower one Flange plate (37) is formed.

The shape of the projecting edge (33) results in (FIG. 2) one mechanical stop immediately after the retraction of the Main bolt (5) is done and before the actuator exposed to excessive forces resulting from that the push rod in a negligent or brutal manner is depressed. A preferred specialty of the invention is that this operating stroke of depressing the movable half bar (1b) for complete retraction the bolt (5,8,9) is smaller than the possible stroke of this push rod is.

This solution makes the locking system more robust, without increasing the material thicknesses used, or that materials with greater durability and cost must be used.

To achieve this goal of achieving greater robustness the fact that (Figures 2 and 4) in the initial and Final states of this operating stroke of depressing the moving Half bar (1b) of the bolt (35) respective positions occupies in the transverse direction perpendicular to the push rod (1) are aligned, and that this bolt (35) in the front End of the slot-shaped opening (34). To this In this way, the projecting edge (33) can counteract when it is in contact the bottom of the fixed half-bar (1a) in the transverse direction with the Start and end positions of the bolt (35) are aligned.

Another preferred feature of the invention is that (Figures 2 and 5 to 9) an actuation module unit (10) is provided which is contained in a cross section which is practical is the same as that of the push rod (1). In the actuation module unit is a device attached in a compact manner that the longitudinal force of the pull rod (4) receives and this in a driving force that converts the main bolt (5) and withdraws upper (6) and lower (7) output elements.

This device includes a graded pull mechanism by a longitudinally displaceable transmission part (11) is formed simultaneously with a first slide (12) and a second slide (13) is coupled to the its front end articulated with a rear pin (14) of the Main bolt (5) is coupled. The main latch contains in inside a locking swivel lever (15) that the Retreat prevented by direct action on its tip. The coupling of the transmission part (11) with the first Slider (12) takes place via an adjustable mechanical play or a delay formed by not depressed push rod (1) a cross bolt (16) on the first slide (12) is attached to a selectively changeable Place along a longitudinal guideway (17) of the transmission part (11) is arranged during the coupling of the transmission part with the second slide (13) over a transverse one Approach (18) of the transmission part (11) takes place a longitudinal groove (19) of the second slide (13) with longitudinal play traverses and against the rear end of the longitudinal groove (19) Plant can come.

The advantages of this new construction are already explained above and refer on the one hand to a versatile application of a modular construction, which in can be mounted reversibly and both for built-in as well as attached locks can be used, whereby the latter case is that in the accompanying drawings is shown, and with the solution of said ES-A1 9002589 is comparable. On the other hand, this device enables the selectively changeable subdivision of the total stroke, which at Depression of the push rod (1) is caused in a Idle stroke and another working stroke which is the retraction of the main bolt (5).

Withdrawing the auxiliary bolts (8,9) simultaneously with the Main bolt (5) is caused by the fact that with the transmission part (11) a transverse pivot pin (20) articulated is coupled, which is eccentrically on a drive plate (21) is attached with radial, diametrically opposite Slots (22) is provided, in which respective transverse pin (23) slide that from an upper (6) or lower (7) Exit the output element, the respective connecting parts (24) for respective actuating rods (25) for the auxiliary bolts (8,9) exhibit. These output elements (6,7) are inclined Provide guideways (26) in which the first (29) and second (30) bolts slide that of first (27) and second (28) turn out rotatable discs that are coaxial to the drive plate (21) are arranged and how these are free with respect to the Axis of a nut (31) are rotatable by an outer Actuating button is operable, which is held on a plate (32) is outside on the bottom of the actuator module unit (10) is attached.

In Figures 5, 7 and 9 it can be seen that the longitudinal guideway (17) and the longitudinal groove (19) in a suitable manner lengthened to the front to an extent that is at least the same is the stroke that the transmission part (11) retracts of the main bolt (5) when the push rod (1) is depressed. When opening using the (not shown) the outer actuating button passes through the cross bolt (16) this front extension of the longitudinal guideway (17) without to take the first slide (12); the front extension the longitudinal groove (19) enables the independent retraction of the Main bolt (5), for example for assembly or inspection processes, without affecting the rest of the actuator becomes.
