EP0799957A2 - Reversible anti panic bar for emergency exit doors - Google Patents

Abstract

The anti-panic bar is fitted to an emergency door (1), and has a horizontal handle or pressure bar (3) which is held freely at one end by a lever (4). The latter can rotate about axes (5) which are parallel to the bar. The bar, the lever, and the mountings which are nearest to the hinge and to the lock, all have the same external shape. The latter mounting (6) contains the axes of the lever, and the axis (8a) of a rotating nut. These axes are perpendicular to one another, and lie in a plane which is normal to the door, and which simultaneously forms a plane of symmetry for the mounting which is nearest to the lock, and a path for rotary motion. The latter is executed by a cam (10), which can drive a first (11) or second (12) arm from a rest position and into an active position in order to operate the lock.

Description

Field of the Invention

The anti-panic bar to which the present invention relates is of the type which is fitted across the width of an emergency door and which has a general construction consisting of a horizontal handle or a push bar which is cantilevered at its ends by levers which are rotatable about respective axes which run parallel to the push rod and are installed in respective brackets which are fastened to the door, these brackets as a lock-side bracket and as a hinge-side bracket in accordance with their greater proximity to the striking plate or to the hinge the door are referred to, wherein the lock-side bracket has a rotatable nut with a virtual axis perpendicular to the door and this nut is installed through the mounting plane between the lock-side bracket and the door.

State of the art

In the known anti-panic bars in most cases, the axes of rotation of the lever and the nut are not contained in the same transverse horizontal plane in the lock-side holder, but rather extend in different such planes so that a lever arm is arranged between the push rod and the nut can, which causes a gentle and sufficient amplitude and strength actuation. This results in an asymmetry which prevents the lock-side bracket from being usable for both right-hand and left-hand opening doors, so that it is necessary to produce different lock-side brackets for each type of door.

Furthermore, some embodiments are known in which these axes of rotation of the lever and the nut lie in the same transverse-horizontal plane to the door, but in these the internal structure is not symmetrical and the conversion to reversibility requires assembly work and / or changes to the internal parts including disassembly of the actual shaft of the lever.

For this reason, the known anti-panic bars either lack the property of reversibility, or this reversibility can only be achieved on the basis of a change in the arrangement of the parts, with the aid of operations which must be carried out by a specialist, which is only acceptable can become because there is no better solution.

This fact gives rise to other additional disadvantages, namely: unfavorable conditions for an aesthetic appearance, difficulty in achieving dimensions that allow the use of the anti-panic bar in the small dimension ranges for doors made of metal profiles or the like, and the difficulty in constructions to create, which are suitable both for mortise locks and for add-on locks in their most common embodiments with a single central locking point in the vertical frame part of the door or with upper and lower locking points via locking parts which are installed on the upper and lower edges of the door.

The problem is of such a magnitude that anti-panic bars are often supplied, which are simultaneously provided with two lock-side brackets, namely a right and a left bracket, one of which is not used and thus causes considerable costs, with additional costs reveal that two different lock-side brackets must be manufactured.

Explanation of the invention and the advantages

The novel anti-panic bar includes said pushrod, levers, and lock-side and hinge-side brackets, which have the same external configuration. Of these, the lock-side bracket has an axis for the lever and an axis for the nut, which are perpendicular to each other and coplanar in a plane that is perpendicular to the door. This level is also the plane of symmetry of the actual lock-side mounting and a rotary movement path, which is formed by a central section for operational presetting and by respective operating end sections, which have the same extent to one another and which are formed at each end of said central section without interrupting the continuity . This operational trajectory is carried out by a cam that is keyed to the axis of the lever of the lock-side bracket, and this cam has an operating part that abuts against one or the other of the first and second drive parts at each end of the central portion of the rotary trajectory can be brought, which start from the respective first and second pivot levers, which are symmetrical with respect to the transverse-horizontal plane of symmetry and which are attached in a floating manner with spring preload. When the cam performs the rotation corresponding to the operating portions of the rotational trajectory, this first or second swing lever is driven to move from a non-rotated or rest position to another rotated or active position, thereby causing a swing operation movement of a mechanism that does so Opening a mortise or add-on lock causes this actuation to be brought about by the pressure exerted by one or the other of first and second edges, each of which emanates from the first and second pivot levers.

In this novel anti-panic bar, the lock-side bracket for doors with right or left opening is reversible, with a simple handling, because it is sufficient to pivot the push rod from one end to the other of the central portion of the rotary path, the Presses cams on one or the other of the first and second pivot levers, which cause the intermediate mechanism to be carried along to open the lock.

Once the direction of operation (right or left) is selected, it is possible to set it because the cam has first and second prongs with such a spatial configuration that when this cam with the actuator against one or the other of the first and second drive parts of the first and second pivot levers abut, a corresponding one of the first and second prongs comes to bear against a respective edge of a stop, which is detachable or is inserted into a removable cover which forms part of the lock-side holder.

The novel formally and functionally symmetrical construction facilitates the achievement of a single construction in which the lock-side bracket and the hinge-side bracket have a configuration with the same shape and external dimensions, both of which have a rectangular, elongated plan in the vertical direction of the door and the overall width within the width lies, which is standardized for metal profiles, the lock-side bracket and the hinge-side bracket are formed by a frame and said removable cover and the frame has a U-shaped cross section along a horizontal plane perpendicular to the door.

The resulting construction is therefore also suitable for doors with metal profiles and the like as well as for mortise locks and for add-on locks with a central locking point and additionally for add-on locks with two locking points, namely an upper and a lower locking point.

In particular, in the embodiment of the anti-panic bar for mortise locks, the practical embodiment can be simplified to such an extent that the first and second pivot levers are combined into a single double-acting lever or a double lever in which the first and second drive parts are designed such that, when this double lever is in the rest position, these first and second drive parts can be positioned corresponding to the beginning of the corresponding one of the operating sections of the rotary movement path of the actuating part of the cam, the double lever having first and second edges which bear against respective first and second edges can be brought, which are formed in a slider that is displaceable parallel to the height of the door, this slider having third and fourth edges that can be brought to bear against respective third and fourth end faces, in a rotatable holder connected to the nut are formed at an eccentric position with respect to the virtual axis of rotation of this nut.

With regard to this embodiment for a mortise lock, the door has in many cases a preprocessing for any right or left assembly such that if one of these types of assembly has been determined, the preprocessing of the unused option remains visible. In order to bring about a solution in such circumstances, an additional plate is provided in the anti-panic bar for this embodiment, which can be fastened to the frame of the lock-side holder via the outside of the contact wall of this lock-side holder on this door, this additional plate being asymmetrical in the longitudinal direction with respect to a through opening for the called axis is the nut. This additional plate has a greater length than the frame of the lock-side bracket, this additional plate has a fastening hole which is formed in the longitudinally extending part which projects over the unit of this lock-side bracket. This additional plate can be aligned with the cover of the lock-side holder over its entire circumference with the exception of the part which is affected by the longitudinally extending overhang. The auxiliary plate also has openings arranged in a shape and position such that when this longitudinally extending overhang is at any of the two ends of the lock-side bracket, these openings in combination with the fasteners the additional plate itself on the frame of the lock-side bracket and finally cooperate with the door.

The application of the invention to an embodiment of the anti-panic bar for add-on locks with a single central locking point (via a bolt which is arranged in the lock-side holder) has a preferred embodiment in which each of the first and second pivot levers has first and second edges which rest in the rest position against respective first and second pins, which are formed in an end part of the bolt, which is arranged inside the lock-side holder, this end part being rotatably installed with respect to a pin, around which the bolt between advanced and retracted positions relative to the lock-side bracket is pivotable. The first and second edges can each assume two positions that are displaced relative to one another, which correspond to the non-pivoted position (rest position) or pivoted position (drive position), in which this bolt each assumes its advanced position or lock-closed position or its retracted or lock-open position.

With regard to the first and second pins of the bolt, first and second seats are provided which are formed in a rocker arm which is rotatably fastened with respect to a pivot axis, this rocker arm being rotatable between respective non-pivoted positions (rest position) and pivoted positions (drive positions), which correspond to the projecting position (closed lock) and retracted position (open lock) of the bolt. This rocker arm has two paired fifth and sixth edges and two paired seventh and eighth edges, the paired fifth and sixth edges in the said rest position against respective third and fourth end faces that can be brought into contact with the nut firmly connected rotatable bracket are arranged in a position which is eccentric with respect to the virtual axis of rotation of the nut. The arranged in pairs In the rest position, seventh and eighth edges can be brought into abutment against respective fifth and sixth end faces, which are formed decentrally in third and fourth pivoting levers, these third and fourth pivoting levers in the other decentred position forming ninth and tenth edges which form in the Can extend rotational path of an eccentric, which starts from a combination lock cylinder which is driven in rotation by means of a key.

The numerical indications (first, second, etc.) and the position (lower, upper), which appear in brackets in the explanation of the functioning, which is explained below, indicate the participation in the functioning of one or the other of these elements in accordance with the handling that occurs in one or the other of the two types of reversible mounting direction of the lock-side bracket, one for a right-hand opening door and the other for left-hand opening doors.

In this embodiment for an add-on lock with a single locking point, the opening process takes place from the inside as follows: when the push rod is actuated, the cam causes the corresponding (first or second) pivoting lever to rotate and with its relevant (first or second) edge it drives the (first or second) pin, which in turn causes the bolt to be retracted by rotating it about the pin on which its end part is attached.

In this embodiment, opening options are also provided from the outside via a square which is actuated via a handle, for example a handle, and via a rod which is connected in a rotationally fixed manner to a combination lock cylinder which is actuated via a key. The opening process via a square causes a rotation of a holder assigned to the nut and then presses the corresponding (third or fourth) of the end faces emanating from the holder of the nut against a respective (fifth or sixth edge of the rocker arm so that it pivots and press its first and second seats on the first and second seats on the first and second pins of the bolt, whereby it is pivoted into its retracted position inside the lock-side bracket. The opening by means of a key causes the eccentric of the locking cylinder to press against the corresponding (third or fourth) pivot lever on its respective (ninth or tenth) edge, so that the corresponding (fifth or sixth) end face of this pivot lever is on the corresponding (seventh or eighth) edge of the rocker arm presses, causing it to pivot, with the same result as the opening over the square. The eccentric is operated by a rod that passes through the thickness of the door and is rotated by a combination lock cylinder that is attached to the back of a door plate in which the door handle is also held.

In order to open with the outer door handle (to close the area), according to the invention, this holder of the nut has diametrically opposite locations on radial first and second lugs, one or the other of which in the vertical direction in a recess with a profile can be accommodated, which is complementary to the first and second radial lugs, this recess is formed in a locking slide which is guided in the vertical direction between unlocked and locked positions. A corresponding one of the third and fourth levers is fastened on this locking part, and this locking part has a first or upper edge and a second or lower edge, such that in the unlocked position said upper edge projects tangentially into a rotational movement path of the eccentric, which is opposite to the opening movement path of the lock and in the locking position, while the lower edge can extend in the tangential direction in a rotational movement path of the eccentric, which is in the same direction of the opening movement path and one revolution in front of this opening movement path.

In order to fix the locking and unlocking positions in a practical manner, a vertical leaf spring is provided, which rests under pressure against the locking part in such a way that this leaf spring has a first end which is anchored on the frame of the lock-side holder and a second end which forms a convex turn toward the latch member, this convex turn cooperating with one of the first and second slots of the latch member such that the incidence of this convex turn into the first and second slots coincides with the unlocked and locked positions of the latch member.

The application of the invention to an embodiment of the anti-panic bar for an add-on lock with two locking positions (by means of locking upper and lower locking parts) has a preferred embodiment in which each of the first and second pivot levers has one of the first and second edges mentioned, which in the Rest position against respective first and second pins, which emanate from a first or lower and a second or upper rail, these first and second pins slidingly passing through respective radial first and second grooves, which are diametrically opposite in a freely rotatable disk are formed coaxially to the axis of the nut. The operational pairs of the first edge and the first pin and the second edge and the second pin are arranged in such a manner that when any one of the first and second levers changes from the non-pivoted position to the pivoted position, there is a mutual approximation of the first and second rails against the elastic return effect of respective return springs.

According to the invention, these first and second rails have respective oblique first and second slots which are slidably traversed by third and fourth pins, respectively, emanating from fifth and sixth levers which are freely rotatably arranged coaxially with the axis of the nut, wherein the fifth and sixth levers first and second, respectively Have projections which can come to rest against a respective fourth or third end face, which are formed in a rotatable holder fixedly connected to the nut, the first and second oblique slots being aligned such that they are from the respective third and fourth pins the movement of mutual convergence between the first and second rails.

In addition to the opening from the inside with the push rod, this embodiment also provides an opening from the outside via a door handle and the possibility of blocking this door handle from rotating via the eccentric of a combination lock cylinder which is actuated by a key.

Opening from the inside consists in that when the push rod is actuated, the cam causes the corresponding (first or second) lever to rotate, with its respective (first or second) edge, the (first or second) pin of a corresponding ( drives the upper or lower) rail, whereupon the (first or second) pin drives the disc (via its first or second radial groove) in rotation, and this disc in turn drives the other (second or.) via the other radial (second or first) groove first) pin of the respective (upper or lower rail), the direction of rotation of the disk being such that the rails simultaneously move in the direction of mutual approach, regardless of which of the (first or second) pins is first driven.

The opening from the outside via the door handle is that when the nut is turned (via the square connected to the door handle), this nut is held with one of its (third or fourth) end edges against a respective (first or second) projection of a corresponding (fifth or sixth) lever to pivot this (fifth or sixth) lever, the respective (third or fourth) pin of the corresponding (lower or upper) rail over the drives corresponding slanting (first or second) slot provided in the latter, wherein when the (first or second) rail moves, the (first or second) pin entrains said disc, which moves the other (second or first) drives the rail according to the mechanism specified for the opening using the internal push rod. The first and second oblique slots are aligned in such a way that in the described opening process with the outer door handle, these rails simultaneously move in the direction of mutual approach.

In this embodiment, a rotary blocking device (locking device) of the outer door handle and a practical determination of the locking and unlocking position is provided in the same manner as in the embodiment of the lock with a single central locking position specified above.

The construction explained for this embodiment with a mutual approach movement of the rails enables the construction of upper and lower closure parts which are advantageously identical to one another. These fastener parts have a special construction which includes a jaw, a jaw carriage, a drag arm, a return spring, a latch, a frame and a removable cover. This jaw consists of a respective fixed jaw and a releasable jaw, which together form an approximately cylindrical passage with variable dimensions and two side flanges which are connected to each other via respective fastening screws. This central passageway has a minimum dimension with an interference fit against the outside diameter of a rod attached to a corresponding one of the rails. The releasable clamping jaw has a third screw which can be screwed through this clamping jaw. The jaw carriage is in the vertical direction in the housing between a normally projecting locking position and a position of the Riegel led in which it is pulled back against the return spring with force. The towing arm is connected to the bolt and can move relative to the jaw slide, this relative displacement being limited in accordance with the above-mentioned projecting and retracted positions of the bolt. The return spring is arranged between the axis of rotation of the bolt and the drag arm. The housing has a U-shaped cross section with the same width as the lock-side bracket.

Representation of a preferred embodiment

With reference to the above-mentioned drawings and reference numerals, in the accompanying drawings there is shown a preferred embodiment of the novel anti-panic bar (2) according to the invention, which is of the type which is installed over the width of an emergency door 81) and which has a general structure which consists of a horizontal push handle or a push rod (3) which is supported at its ends by self-supporting levers (4) which rotate in respective shafts (5) which run parallel to the push rod (3) and which in each case on the Door (1) fastened brackets are installed. These brackets are called lock-side bracket (6) and hinge-side bracket (7) according to their respective closer proximity to the striking plate or to the hinges of the door (1). The lock-side bracket (6) has a rotatable nut (8) with a virtual axis (8a) perpendicular to the door (1), this nut (8) through the plane of contact between the lock-side bracket (6) and the door (1 ) is installed through it.

A first essential aim of the invention is to provide a reversible or reversible construction which enables the use of the same lock-side bracket (6) for a door with a right-hand opening or a door with a left-hand opening, by means of a simple handling that is within the range of possibilities any person lies and does not require changing the arrangement of the parts of the mechanism.

For this purpose, the novel anti-pan rod (2) comprises said push rod (3), said levers (4) and the lock-side bracket 6 and the hinge-side bracket (7), which have the same external shape. The lock-side bracket (6) contains the shaft (5) of the lever (4) and the axis (8a) of the nut (8) which are perpendicular to one another and coplanar in a plane which is perpendicular to the door (1) and which is the plane of symmetry of the actual lock-side holder (6) and a rotary movement path (9), which is formed by a central section (9a) for an operational initial setting and by two operating end sections (9b), which have the same extension and which are on without interruption each end of the central section (9a) are formed. This operational movement path (9) is defined by a cam (10) which is wedged with the shaft (5) of the lever (4) of the lock-side bracket (6). This cam (10) has an actuating part (10a) which can be brought into abutment at each end of the central section (9a) of the rotary movement path (9) against one or the other of first and second drive parts (11a, 12a), which by the respective first and second pivot levers (11) and (12), which are symmetrical with respect to the transverse-horizontal plane mentioned, are designed with a floating spring-loaded fastening are. When the cam (10) performs the rotation corresponding to the operating portions (9b) of the trajectory (9), the first swing lever (11) or the second swing lever (12) is driven to move from an untwisted or rest position to one move the twisted or active position, causing an actuating pivotal movement of a mechanism that causes the opening of a mortise lock or an add-on lock, the actuation of which is caused by the driving force of one or the other of first and second edges (11b, 12b) each start from the first or second pivot lever (11, 12).

The working position (right or left) selected for the lock-side holder (6) is determined in that said cam (11) has first and second prongs (10b, 10c) with a spatial shape such that when the cam (10) with the actuating part (10a) against one or the other of the first and second drive parts (11a, 12a) of the first and second pivot levers (11) or (12), one of the corresponding one of the first and second prongs (10b) or (10c) is brought into abutment against a respective edge of a stop (15) which can be detachable or which is combined with a detachable cover (4) which forms part of the lock-side holder (6).

The process of reversing (Figures 1 to 7) is accordingly a removal (Figure 4) of the stop (15), which in this case is connected to the detachable cover (14), whereupon the push rod (3) is pivoted upward and then the cover (14) is replaced so that (Figure 5) the stop (15) prevents the push rod (3) from moving down again. Then the lock-side bracket (6) can be rotated so that the entire unit assumes the starting position (Figure 3), with the difference that when the push rod (3) is actuated, the cam (10) acts on the second pivot lever (12) , and not on the first swivel lever (11). From this simple process it follows that the same lock-side bracket (6) used for installation on a door Right opening (Figures 1 and 2) is provided, can also be installed in a door with left opening (Figures 6 and 7).

An important additional advantage of the construction described is that it can be used for locks which can be inserted into the body of the door (1) and for locks which are built on the door, both in an embodiment with a single locking point via a bolt (19), which is contained in the actual lock-side holder (6), as well as in embodiments with two locking points, namely an upper and a lower locking point, with the aid of locking parts (28 and 29), which start from the lock-side Bracket (6) are operated via rods (39) which are connected to displaceable lower (30) and upper (31) rails which are installed in the actual lock-side bracket (6).

Another important advantage is that any of the above-mentioned embodiments always have the same external appearance in terms of shape and dimensions, and the proposed construction also enables the construction to be carried out within the dimensions suitable for installation with the limited dimensions that are possible in emergency doors (1), which are built on the basis of metal profiles or the like. Because the lock-side and hinge-side brackets (6, 7) have a configuration with the same shapes and external dimensions, both have a rectangular plan that is elongated in the vertical direction of the door (1), the overall width being within the width for metal profiles is standardized, the lock-side bracket (6) and the hinge-side bracket (7) being formed by a frame (13) and the detachable cover (14), the frame (13) having a U-shaped cross section along a horizontal plane perpendicular to the door (1).

In the embodiment of the anti-panic bar (2) for a mortise lock (FIGS. 8 to 23), the first and second pivot levers (11, 12) form a single double-acting pivot lever or combined double lever (11-12), in which said first and second drive parts (11a, 12a) are formed such that in the rest position of this double lever (11-12) the first and second drive parts (11a, 12a) corresponding to the beginning of the corresponding one of the operating sections (9b) of the rotary movement path (9) of the actuating part (10a) of the cam (10), this double lever (11-12) having the said first and second edges (11b, 12b), which against one respective first (16a) and second end faces can be brought into contact, which are formed in a sliding piece (16) parallel to the height of the door (1), this sliding piece (16) having a third (16c) and fourth (16d) edge which can be brought into abutment against respective third (17a) and fourth (17b) end faces, which in a rotatable holder (17) connected to the nut (8) at an eccentric position with respect to the virtual axis of rotation (8a) of this nut (8 ) are trained.

With reference to FIGS. 11 to 14, the mode of operation of this embodiment consists in that when the push rod (3) is actuated, the cam (10) is driven in rotation and with its actuating part (10a) against the first drive part (11a) of the first pivot lever ( 11) presses. This first pivot lever (11) is pivoted (FIG. 13) and presses with its first edge (11b) against the first end face (16a) of the sliding piece (16). This slide (16) presses with its third edge (16c) against the third end face (17a) of the holder (17) of the nut (8), whereby this nut (8) is rotated and via the corresponding square (49) the opening of the Mechanism of the mortise lock in the door (1) actuated. The same operation results in the reverse position, with the exception that the elements involved are then the second drive part (12a), the second pivot lever (12), the second edge (12b), the second end face (16b), the fourth edge (16d) and the fourth end face (17b) are instead of the corresponding elements mentioned above.

In many cases, the doors (1) prepared for mortise locks have preprocessing for the two assembly options, and if one of the options is selected, it is possible that the unprocessed preprocessing is visible.

In this case, the invention provides for the presence of an additional plate (18) which can be fastened to the frame (13) of the lock-side bracket (6) on the contact wall of this lock-side bracket (6) on the door (1). This additional plate (18) is asymmetrical in the longitudinal direction with respect to a through opening (18a) for the axis (8a) of the nut (8) and has a greater length than said frame (13) of the lock-side holder (6), this additional plate ( 18) has a fastening hole (18c), which is formed in the projecting longitudinal part (18b) beyond the unit from this lock-side holder (6), this additional plate (18) with said cover (14) of the lock-side holder (6) is arranged smoothly with respect to the circumference, with the exception of the part which is influenced by said longitudinal overhang (18b). This additional plate (18) has openings (18d) which are arranged with a shape and position such that when the overhang (18b) lies in the longitudinal direction against one of the two ends of the lock-side holder (6), these openings (18d) cooperate with the fastening means of the additional plate (18) on the frame (13) of the lock-side holder (6) for their final fastening to the door (1).

With regard to the above-mentioned embodiment of the anti-panic bar (2) for an add-on or built-on lock (FIGS. 24 to 43) with a single central locking point with the aid of the said bolt (19), it can be seen that each of the first (11) and second (12) Swivel lever has said first (11b) and second (12b) edges, which in the rest position bear against respective first (19b) and second (19c) pins, which is formed on an end part (19a) of the bolt (19), which is in the Inside the lock-side bracket (6) is arranged, this end part (19a) is arranged rotatably with respect to a pin (20) on which this bolt (19) can be pivoted between retracted and extended positions with respect to this lock-side holder (6). The first (11b) and second (12b) edges can each assume two mutually offset positions, which correspond to the non-pivoted (rest) position or the pivoted (drive) position, in each of which this bolt (19) is its extended or closed position or occupies its retracted or lock opening position.

This construction enables opening via the push rod (13) in such a way that (FIGS. 29 and 30) when the push rod (3) is actuated, the cam (10) is caused to rotate, so that its actuating part (10 a) against the first drive part ( 11a) of the first pivot lever (11), whereby its first edge (11b) finally presses against the first pin (19b) and the bolt (19) is pivoted to its retracted position in the lock-side holder (6). In the reverse position of the lock-side bracket (6), the elements involved in this function are the second drive part (12a), the second pivot lever (12), the second edge (12b) and the second pin (19c), instead of the aforementioned corresponding elements.

In this embodiment for an add-on lock, it is also possible for an opening to take place from the outside via an outer door handle (50), which is fastened to a square (49), and via an eccentric (25), which via a door (1 ) traversing rod (51) is rotated via a locking cylinder (26) which is actuated with the aid of a key (27) and which is fastened on the back by a door plate (52) in which the door knob (50) is also held.

For this purpose, first (21a) and second (21b) seats are provided with respect to the first (19b) and second (19c) pins of this bolt (19), which are formed in a rocker arm (21) which is rotatable with respect to a pivot axis (229 attached is, wherein this pivot lever (21) is rotatable between non-pivoted (rest) and pivoted (drive) positions, which correspond to the above advanced (locked lock) and retracted (open lock) positions of the bolt (19). This pivoting lever (21) has a twin pair of fifth (21c) and sixth (21d) edges and a twin pair of seventh (21f) and eighth (21g) edges, the twin pairs of fifth (21c) and sixth (21d) edges in This rest position can be brought to bear against respective third (17a) and fourth (17b) end faces which are arranged in a rotatable holder (17) which is firmly connected to the nut (8) at a position which is relative to the virtual axis of rotation (8a). the nut (8) is eccentric. In this rest position, the aforementioned pairs of seventh (21f) and eighth (21g) edges can be brought into contact against respective fifth (23a) and sixth (24a) end faces, which are formed decentrally in respective third (23) and fourth (24) levers in the other off-center position, these third (23) and fourth ((24) levers have ninth (23b) and tenth (24b) edges which are in the rotational movement path of an eccentric (25) which is guided by a locking cylinder (26 ) goes out, which is operated with the help of a key (27) in rotation.

In this construction, the opening by means of the outer door handle (50) takes place (FIG. 31) in that the third end face (17a) of the holder (17) presses the nut (8) against the fifth edge (21c) during rotation and the pivot lever (21) pivoted, which presses with its first (21a) and second (21b) seat against the first (21a) and second (21b) pins and causes the bolt (19) to retract into the interior of the lock-side holder (6) becomes. In the inverted position, the elements involved are the fourth end face (17b) and the sixth edge (21d) instead of the corresponding parts mentioned above.

The opening by means of the key (27) (Figures 32 and 33) is that when the eccentric (25) is rotated by the rod (51) connected to the locking cylinder (26) is actuated, this eccentric presses against the ninth edge (23b) of the third lever (23) which, when pivoted, presses with its fifth end face (23a) against the seventh edge (21f) and the pivoting of the rocker arm (21) causes, with the same result as when opening with the help of the outer door handle (50). In the inverted position, the elements involved are the tenth edge (24b), the fourth lever (24), the sixth end face (24a) and the eighth edge (21g), instead of the corresponding elements mentioned above.

It is possible to block or lock the rotation of the outer door handle (50) (FIGS. 34 and 35), the holder (17) of the nut (8) for this purpose being diametrically opposite radial first (17c) and second (17d) Has approaches, one or the other of which can be gripped in the vertical direction by a recess (47a) with a profile complementary to these radial first (17c) and second (17d) radial approaches. This recess (47a) is formed in a displaceable bolt part (47) which is guided in the vertical direction between unlocked and locked positions, a corresponding one of the third (23) and fourth (24) bolts being fastened on this bolt part (47). This locking part (47) further has a first or upper edge (47b) and a second or lower edge (47c) in such a way that, in the unlocked position, this upper edge (47b) in the tangential direction a rotational movement path of the eccentric (25) in the opposite sense can lock the opening movement of the lock. In the locking position, said lower edge (47c) can block a rotational movement path of the eccentric (25) in the tangential direction, which takes place in the same movement path for opening and upon rotation of this opening movement. That is, to lock the rotational movement of the outer door handle (50), the key is turned in a direction opposite to the opening movement, with the eccentric (25) pressing against the first edge (47b), and the locking part (47) then moves upward until it has the first radial extension (17c) of the holder (17) in its recess (47a) Nut (8) receives, whereby the rotation of the bracket (17) and thus the nut (8) and the door handle (50) is blocked. With the locking part (47), the third lever (23) is moved in such a way that unlocking by opening the eccentric (25) (which then rotates in the normal opening direction) against the second edge (47c) results in re-opening, whereupon then, with the locking part (47) in its initial position, again moving the ninth edge (23b) of the third lever (23) into the position in which it moves through the eccentric (25) when the key (27) is turned a second time in the normal direction Opening direction is operated.

In order to fix the positions of the locking and unlocking of the locking part (27) (FIGS. 24, 25 and 34) in a simple manner, a vertical leaf spring (48) is provided which presses against the locking part (47), this elastic leaf spring ( 48) has a first end (48a) which is anchored to the frame (13) of the lock-side holder (6) and a second end (48b) which has a convex bend (48a) in the direction of the locking part (47) , said convex bend (48c) cooperating with one or the other of the first (47d) and second (47f) slots of the locking part (47) such that the incidence of this convex bend (48c) in the first slot (47d) and the second slot (47f) coincides with the unlocked and locked positions of this locking part (47).

In the mentioned embodiment of the anti-panic bar (2) (FIGS. 46 to 64) for an add-on lock with two locking points via upper (28) and lower (29) locking parts, it can be seen that each of the first (11) and second (12) pivot levers is first (11b) and second (12b) edges, which can come into abutment against said first (30a) and second (31a) pegs in the said rest position, which are formed by a first or lower rail (30) and a second or upper rail (31 ) going out. These first and second pins (30a, 31a) pass through first and second radial slots (32a, 32b) which are diametrically opposed in a disk (32) which is freely rotatable and arranged coaxially to the axis (8a) of the nut (8). The said operational pairs of the first edge (11b) and the first pin (30a) and the second edge (12b) and the second pin (31a) are arranged such that when any one of the first and second pivot levers (11, 12 ) passes from the non-pivoted position into the pivoted position, a mutual approach of the first and second rails (30, 31) results against the elastic return action of return springs.

In this construction, the opening process from the inside with the aid of the push rod (3) (FIGS. 51 and 52) consists in that the first edge (11b) of the first pivot lever (11) against the first pin (30a) of the first rail (30) presses, which causes it to move out of the lock-side bracket (6). At the same time, the first pin (30a) passes through the first radial slot (32a) of the disc (32), which drives it in rotation and, via the second radial slot (32b), picks up the second pin (31a) of the second rail (31), so that this is also moved out of the lock-side bracket (6). In the reverse position of the elements concerned, it is the second edge (12b) of the second pivot lever (12) which then first acts on the second pin (31a) of the second rail (31), which also causes movement via the disc (32) of the first pin (30a) of the first rail (30).

In this position it is also possible to use an outer door handle (50) to open it. For this purpose, the first (30) and second rails (31) have first and second oblique slots (30b, 31b) through which third and fourth pins (34a, 35a) pass, which are guided by fifth and sixth levers (34 , 35) which are freely rotatably fastened coaxially to the axis (8a) of the nut (8), the fifth and sixth levers (34, 35) having respective first and second projections (34b, 35b), which each rest against the other against a fourth end face (17b) and one third end face (17a) can be brought, which are formed in a rotatable holder (17) which is fixedly connected to the nut (8). The slanting first and second slots (30b, 31b) are oriented so that they pass through the respective third and fourth pins (34a, 35a) as the mutual approach between the first and second rails (30, 31) moves.

According to this construction, the opening takes place by means of an outer door handle (15) in that when the door handle (50) is actuated, the holder (17) of the nut (8) is rotated and, with its fourth end face (17b), a driving force on the first projection (34b) of the fifth lever (34), whereupon the third pin (34a) of this fifth lever (34) acts on the first oblique slot (30b) of the first rail (30), so that this first rail (30) is operationally displaced and with its first pin (30a) causes the rotation of the disk (32) via the first radial slot (32a). This disc (32) takes the second pin (31a) of the second rail (31) with it via its second radial slot (32b), so that it is also shifted during operation. When the lock-side bracket (6) is in the reverse position, the operating sequence is the same, but the third end face (17a) of the bracket (17) acts on the second projection (35b) of the sixth lever (35), the fourth pin (35a) this sixth lever (35) acts on the second oblique slot (31b) of the second rail (31) and the second pin (31a) of this second rail (31) acts on the second radial slot (32b) in order to prevent the rotation of the disc ( 32) operationally move the first rail (30) simultaneously with the second rail (31).

In this embodiment, there is the possibility of blocking the rotation of the door handle by a mechanism which is identical to that described for the embodiment with a single locking point, that is to say via said locking part (47), via an external key (27) in the locked and unlocked position is moved, the working positions of this locking part are determined in a practical manner by the said elastic leaf spring (48).

In this embodiment, the opposing movement of the first and second rails (30, 31) into the interior of the lock-side bracket (6) enables upper and lower closure parts (28, 29) to be constructed which are identical to one another. These upper and lower closure parts (28, 29) have (FIGS. 61 to 64) a special construction which comprises a jaw (36-37), a jaw slide (41), a drag arm (42), a return spring (43) , a latch (44), a housing (45) and a removable cover (46), wherein the jaw (36-37) consists of a fixed jaw (36) and a releasable jaw (37), which together form an approximately cylindrical form a central passage with variable dimensions and have respective lateral flanges which are connected to one another via respective fastening screws (38). This central passageway has a minimum dimension of interference fit with the outside diameter of a rod (39) attached to the corresponding one of the rails (30, 31) and the movable jaw (37) has a third screw (40) which can be screwed through this jaw. The jaw carriage (41) is guided in the vertical direction in the housing (45) between a normally projecting position of the bolt (44) and a position of the bolt (44) which is retracted by the action of force against the return spring (43). The towing arm (42) is connected to the bolt (44) and can move relative to the clamping jaw carriage (41), this relative movement being limited in accordance with the projecting and retracted positions of the bolt (44). The return spring (43) is arranged between the axis of rotation (44a) of the bolt (44) and the drag arm (42), and the housing (45) has a U-shaped cross section with the same width as the lock-side bracket (6). The relative movement between the trailing arm (42) and the slide carrier (41) is limited by a wing (42a) of the Tow arm (42) which traverses a slot (41a) of the slide carrier (41) with vertical displaceability.

Because in the projecting position of the bolt (Figures 61 to 63) said wing (42a) bears against that end of said slot (41a) which is closest to the bolt itself, pulling the rod (39) in the direction of the the lock-side bracket (6) of the drag arm (42) is pulled along by the clamping slide (41), whereby the return spring (43) is elastically loaded until the retracted position of the bolt is reached (FIG. 64). Independent retraction of the bolt (by exerting direct pressure on it, for example by moving against its striking plate) is possible because the vertical extension of the slot (41a) is greater than the retraction movement of the bolt, and the wing (42a) is over the entire Length of this vertical slot (41a) out. Although the rod (39) can be fastened sufficiently by tightening the screws (38), additional securing is achieved by means of a third screw (40) which has a hardened tip that extends into the surface of the rod (39 ) can notch.

The push rod (3) is fastened to the levers (4) (FIGS. 8 and 9) by means of a screw-type spreading device, which consists in the fact that the levers (4) have expandable clamps (53) which are located inside the push rod (3) take up an expanding nut (54), which increases its cross-section starting from the corresponding lever (4), the smallest cross-section of the expanding nut (54) being adapted to the dimension which exists between the tips of the clamps (53) when they are at rest (or not expanded) before attachment. The expansion nut (54) is screwed onto an actuating screw (55), the shaft of which is located in the middle of the clamps (53) and the actuating head is on the opposite side of the lever (4).

When the actuating screw (55) is turned, the expanding nut (54) with its increasingly larger cross section penetrates between the clamps (53), causing them to be pushed apart or expanded (FIG. 9), as a result of which increasing pressure is exerted on the inner wall of the push rod (53) and this results in a firm fixation.

The ends of the push rod (3) are inserted into channels (56) of the lever (4), which means that imperfect finishes are covered when the ends of the push rod (3) are cut off.

After the nature of the present invention and its commercial implementation have been sufficiently described, it should only be mentioned that changes in form, materials and arrangement can be made in their entirety and in their components, all of which do not affect the basic idea.
