Abstract

In espagnolette fastenings without a panic function, which are provided on the standing wing (1) of two-wing doors, the espagnolettes (2) are under the effect of a spring (11), seeking to press them into the extended position, and of a blocking device (12) which, with the wing (1) opened, hold the espagnolettes (2) in their retracted position, but during the closing of the wing (1) release them for their extension movement, in which they move with their outer ends in closing holes arranged on the doorframe at the top and bottom and thereby lock the standing wing (1). To prevent an unauthorised pushing open of doors (1) equipped with such espagnolette fastenings as a result of an unpermitted retraction of the espagnolettes (2), even when the gangway wings are properly closed, in their extended position the espagnolettes (2) are to be closed by means of a key-actuable lock (16) and a blocking member (for example, 18) actuable thereby and are to be released only by the actuation of the latter by a key. The closing of the espagnolettes (2) in their extended position can likewise take place by key actuation, but preferably also automatically. <IMAGE>

Description

I §! 70 3565

Connecting rod lock without function in case of panic, especially for the fixed wing of two-winged pine.

The invention relates to a connecting rod lock without function in the event of panic, in particular for the fixed wing of two-leaf doors, provided with at least one connecting rod which can be moved by an operating handle via an operating eye, which is under the action of a hair spring trying to be pressed in the pressed-out position and cooperates with a locking device mounted on the top of the door leaf, which keeps the connecting rod in its retracted position when the door leaf is opened, but on the other hand automatically retracts it when the door leaf is closed her last mentioned 10 latched expressed state.

Connecting rod locks of this kind are known from the German "Offenlegungsschrift" 2.611.359 », but here incidentally with function in the case of panic, in which two transmission levers for the event of panic ensure that when opening the connecting rod lock, the tongue and the fall of the lock of the movable wing are pushed back, so that the two-leaf door can be opened. However, in the case of two-leaf doors, such connecting rod locks are used without the aforementioned levers in case of panic, ie without function in case of panic, for the fixed wing, in particular in cases where the fixed wing only occasionally such as, for example, moving through larger, space-consuming objects and the like, must be opened, and thus usually closed. The blocking device provided with such connecting rod locks at the top of the door wing ensures that the main pairs, i.e. above and below the connecting rods present in the retracted position, are blocked in their retracted position when the door wing is opened, but when closing of the wing for its expressing movement, so that the outer ends of the two connecting rods move into the lock openings 30 present in the door frame above and below, and can thus lock the door. For this purpose, the blocking device is provided with an auxiliary trap, which is pressed inwards when the door leaf is closed, thus influencing the blocking device with regard to the release of the connecting rods.

8202928; v 2

With these Known connecting rod locks without function in case of panic, there are still considerable shortcomings for the vessel concerned. For example, the two-wing doors equipped with the fixed wing can also be lubricated by Bet according to the instructions of the Beveeg-5 Bare wing, which are still unauthorized to open, because the connecting rod lock is attached to the fixed wing by means of the operating handle. the open position is arched, and then the door wings are pushed open with a relatively small effort. Here it is inevitable that the pre-closed tongue and the trap 10 will, under circumstances, even bend a number of traps in the movable wing and the lock holes in the fixed wing be bathed. Bet is also unauthorized to open doors fitted with such connecting rod locks. thefts, such as, for example, in fern tubes or storage areas ,. as a result of which unnoticed skilfully stored goods can be carried away.

The object of the invention, therefore, is to provide a connecting rod lock of the type concerned, which provides a greater safety against. open Offers and cannot be used in the open position by unauthorized persons. This task is solved according to the invention, in that the connecting rod can be locked in the pressed-out position by a lock actuated with a key, which is provided in Bet Particularly with a lock cylinder and thus Operatable locking member and can only be released by the accompanying key operation thereof. In this way, Bet connecting rod lock without function can be closed in case of panic and can only be released by Bet using the appropriate key by authorized persons.

Bet can advantageously be closed off the connecting rod. When Bet is pressed out, this takes place automatically, for which purpose the locking member is under the compression of a locking spring which can be pressed continuously into the locking position. In this mode it is ensured that Bet connecting rod lock When Bet is closed of the door leaf and Bet expressed as the thus locked connecting rods is in any case closed and the BALVE Bet from forgetful action can be prevented from permanently closing Bet connecting rod lock.

35 The connecting rod lock can also be designed in such a way that locking the connecting rod in the pressed-out position is also 82 0 2 9 2 8 ..................... ...........................-..................

3 of which can only be performed. by an associated key operation. Advantageously, the Let locking member can consist of a bar end between the inner inner rod and the lock cylinder, the pair of scissors which can be operated by the latter, and levers with an extension of 5 Let push rod ends lying in Let, whose locking lever ends are for Let. inner end of the pushed-out connecting rod and thereby lock it against retraction. This gives a solid locking of the connecting rod.

For tubular frame doors with the characteristic small 1o tongue size, the locking element advantageously exists with a transverse sliding bolt slide with locking cam, which can be brought in in a locking recess of a control slide connected directly or indirectly to the connecting rod.

The invention is further elucidated to the Land of the drawing, in which:

Fig. 1 - 3 Please note that a pair of locking levers fitted with a connecting rod lock with 'automatic lockable connecting rod in different working positions of the connecting rod and Let pair showing locking levers, fig. Fig. 5 is a sectional view taken on the line V - V in Fig. h, Fig. 6 shows the connecting rod lock intended for pipe frame doors, Fig. 7 and Fig. 8 show pipe frame connecting rod lock in the opened or locked position of the locking slide, FIG. 9 is a sectional view taken on the line IX - IX in FIG. 6, FIG. 10 is a plan view of the tubular frame connecting rod lock with automatic lockable connecting rod and the lock cover removed.

30 and FIG. 11 is a view rotated through 90 ° of the lock according to FIG. 10.

The connecting rod lock without function in the fixed wing 1 of a two-leaf door, shown in fig. 1, in the event of panic, is provided with two connecting rods adjustable in the opposite direction, of which only the upper connecting rod 2 is shown. The operation of the connecting rods is effected by means of an operating handle (not shown) and one. externally toothed actuating eye 3S which is continuously in drive connection with the correspondingly toothed, bent connecting rod end 2 '. The inner connecting rod-5 end 2 'is additionally guided by a pin 6 mounted in a slot of the lock plate 5. Another corresponding key guide U, 6 is still located at the connection point 7 of the three-rod 2, where furthermore a support arm 8 with a spring plate 9 is provided, the latter resting on the two helical compression springs 11 wound around guide bolts 10. These springs 10 traverse the connecting rods 2 coupled via the operating eye 3 in the pressed-out position according to FIG. 1 thereof. to print or keep them there.

The upper connecting rod 2 cooperates with a blocking device arranged on the upper side of the door leaf 1, generally designated 15 with reference numeral 12, which is of the type described in German Offenlegungsschrift 2,912,881. This arrangement basically consists of a clamping plate 135 gripping around the upper end 2 "of the connecting rod which is held by a spring 1U in such a tilted position that the connecting rod 2 20 is thus retracted when it is also compressed of the springs 11. Only when the leaf 1 is closed and an auxiliary drop 15 of the blocking device 12 collides with a stop present at the top of the door frame and is thereby pressed in, does the clamping plate take place 13 and thus release the connecting rods 2, which thus move inwardly with the outer ends in correctly positioned lock holes at the top and bottom of the door frame and thus lock the door in the correct manner.

In the inner connecting rod end 2r, the actuating eye 3 and the springs 11 receiving a lock box 5, a lock that can be operated by a key is provided, in particular a profile lock cylinder 16, and a lock beard between this cylinder and the inner connecting rod end 2 '. 17 of the lock cylinder, scissor-shaped pair of locking levers 18 with a scissor jaw 18 * lying in line with the connecting rod end 2 '. This pair of bolt levers consists on the one hand of the two-35 arms ,. pivotally mounted tumbler 20 above the lock cylinder 16 on the plant 19, and on the other hand from the one-arm, pivotally mounted straight lever 22, laterally adjacent to the lock cylinder 8202928 * 5 in position 21. The two levers are essentially between the pivot bearing positions 19, 21 thereof, tap 23 on the straight lever 22 and an engaging slot 21 in the rocker arm 20 are hingedly connected to each other.

5 Tumbler 20 engages a torsion spring 25, one leg of which rests against the stud 26 in the lock case plate 5 and with the other leg against a stud 20T of the tumbler 20 .. This spring 25 continuously tries to pressing the pair of locking levers 18 into the locking position shown in FIG. 1, wherein the locking lever ends 20 ", 22", that is when the shear jaw 18 'is closed, when the push rod 2, 10 are closed, for the inner end 2, M lie of the pushed-out connecting rod 2 and thus lock it against retraction.

The. at the height of the pivot bearing location 21, the straight lever 22 is further provided with a lock beard latch 22 *, which extends in the open position of the pair of locking levers (fig. 2) in the sweeping path.

If, on the basis of the closed condition of the pushed-out push rod 2 shown in Fig. 1, it must be retracted before opening the fixed wing 1, the lock bit 17 of the profile cylinder lock 16 must first be actuated by a suitable key operation of the profile cylinder lock pair of locking levers 18 are brought into their open position shown in FIG. 2, the lock beard 17 moving against the bottom surface 201'1 of the rocker arm 20 serving as the control surface and thus pivoting it as well as the straight lever 22 accordingly .

The lock beard 17 hereby collides with the lock beard latch 22 *, so that the key respectively the lock beard remains in this position and can hold the pair of locking levers 18 in the open position, until the connecting rods are actuated via the operating eye 3 by means of an associated actuation of the operating handle 2 are brought into the retracted position, so that after the movable wing has first been opened, the fixed wing can be opened without further ado. Then, when the key is pulled out, the pair of locking levers enters the position r shown in FIG. 3, so that the inner connecting rod end 2 'is located in the suitably wide open lock jaw 18' of the pair of locking levers 18. When from this position, The position corresponding to the opening of the fixed wing, which is closed, is moved by the corresponding locking device 12 8202928 6 the three rod 2 under the action of its springs 11 into the pressed-out position, after which the pair of locking levers 18 automatically enters its locking position shown in FIG. 1, it engages with certainty behind the hinnest connecting rod end or in front of its end face. The locking levers 20, 22 are sized so that the connecting rod cannot be retracted in the case of a violent attempt to open via the operating handle connected to the operating eye 3. Instead, it is ensured that, even when a large torque is applied to the operating handle, all parts 10 of the connecting rod lock can absorb this torque, and as the fourth link in the chain of all loaded refrigerated parts, the square pin mounted in the operating eye 3 3 'destroyed by torsion breakage.

Unauthorized opening of the door is therefore practically impossible. By changing the square pin in the actuating eye 3, the float rod lock can be made completely cold again.

The connecting rod lock shown in Figs. K and 5 is largely of a similar quality as the lock described above. In the first place, it is different that the connecting rod lock shown in Figs. K and 5 does not guarantee automatic locking thereof when the connecting rods are pressed out, but that an adapted key operation is also required for this. For this purpose, the tumbler is 20

front axles of a third lever arm 20, which engages on the other side around the profile cylinder lock 16 and here has another lower control surface 20, which in the open position of the pair of locking levers 18 extends in the path of movement of the lock beard 17, so that it passing this control plane, the pair of locking levers 18 pivots into its closed position shown in FIG.

In order to secure the pair of locking levers 18 in their opening and closing positions, a three-arm tumbler 20 is provided with resiliently supported engagements 30 which can engage one of the engagement holes 31 suitably provided in the lock plate 5 311. As shown in Fig. 5, the engagements 30 are slidably housed in a sleeve 32 located in the tumbler 20. The spring 33 acting on the pin abuts a plurality of the sleeve end 32 '. 35 fibrous, turned-in lips 3 ^ ·

On the side 8202928 * 7 of the rocker arm 20 opposite the straight lever 22, as shown in Fig. B, there is also provided another swinging-arm locking lever 35 which is pivotable about the hinge pin 36.

This locking lever 35 rests with one end thereof and a carrier pin 37, which is present thereon. against. the tumbler 20, while the other end 38 thereof, in the open position of the pair of locking levers 18 and the tumbler 20, respectively, extends in the path of movement of the lock beard 17, so that it always. only a rotation can be closed and closed.

The beer connecting locks described in fig. 6-11 are, without exception, intended for pipe frame doors, of which the smaller tongue size A according to fig. 6 requires a particularly narrow construction. In this connection, the tubular frame connecting rod lock shown in Fig. 6 also has a lock box 5, which contains an operating eye 3, protrudes out of the upper end of the connecting rod 2 and which protrudes. by the pressure relief springs 11 '. can be held in the expressed position and can be obstructed by the blocking device 12 with the auxiliary trap 15 therein.

As shown in Fig. 10 in particular, the inner connecting rod end 2 '"is hereby formed in sliding form and via the fixed

20 slate pins 1 * 0, 1 * 1 and 1 * 2 enveloping key IV V VI arranged in the lock case 5

2, 2 and 2 of them are alloyed in the lock case tube. The connecting rod end 2'1 'is further provided with a driving pin 1 * 3, which engages in the slot 1 * 1 *' of a tilting lever 1 * 1 * pivotable around the housing pin 1 * 0, which at the opposite end thereof has a matching slot 1 * 1 * "trembles, 25 in which a carrier pin 1 * 5 'present on the operating mechanism 1 * 5 engages.

In order to close the connecting rod 2 in its pushed-out position 8202928 i v 8, a profile cylinder lock 16 with lock cam 17 should also be used here. As a difference with the three-rod lock according to the fig. 1 to 5, however, at the tubular frame connecting rod lock, instead of the scissor-shaped pair of latch levers 18, there is provided a relatively narrow latching transverse latch slide ^ 7, which slips ^ 7 'thereof over the housing pin b2 and with a guide 7 "thereof engages in the slot 5 'present in the lock case housing, and thus thus receives a corresponding horizontal guide in the lock case housing. Furthermore, locking lugs 7 on either side * + 7" are provided. 10 of which the locking cam VT, r can engage in a locking recess present at the lower end of the operating slide b $, in accordance with the locking position of the locking slide bj shown in Fig. 8. At the same time, the other locking cam ^ -7 ^ engages under the lower edge 2 at the inner connecting rod end 2 '*'. As a result, the connecting rod in its pressed-out position is, as it were, two-fold locked by the on the operating slide bj on either side.

When the lock must be through the operating eye 3. opened, the locking slide ^ 7 must be moved into the open position thereof shown in FIG. 7 by means of an adapted key operation of the profile cylinder 16. In accordance with Fig. 9, the spring-loaded engaging ball U8, which can engage in engaging holes 31, 31 ', which are fitted in the lock case housing wall, according to Fig. 9, is to be secured in the two locking positions. Fig. 10 and 11 tube frame connecting rod lock shown is distinguished from the above described lock only in that the closing of the connecting rod in the pressed-out position takes place automatically.
