Show it:

Fig. 1 is a schematic partial representation of a gene zweiflügeli door with active and inactive leaf cut in the horizontal,

FIGS. 2a and 2b is a view of the device for explaining the function of the vertically movable thrust rod and the deflection device,

Fig. 3 shows a modified embodiment of the invention,

Fig. 4 shows a further modification of the device according to the invention, and

FIGS. 5 and 6 show a further modification of the inventive apparatus.

In the embodiments according to FIGS . 1 and 2, the active leaf is provided with a vertically adjustable push rod 1 , which carries different, vertically spaced Rie gel 2 , 3 , 3 a, which rule between the locking position and an unlocking position by the push rod movement are. The active leaf is labeled 4 . The latch 2 , 3 , 3 a engage in the closed state of the Gehflü gels 4 in corresponding recesses or locks of the standing wing 5 , as is known per se. In addition, locking bolts can be placed on the push rod 1 above and / or below, which engage in the closed state of the active leaf 4 in corresponding openings in the door frame.

The passive leaf 5 is equipped with a locking device 8 , which in the embodiment shown consists of two push rods 8 a, 8 b, although only one push rod can be provided. The two push rods 8 a, 8 b are mechanically connected to a mechanical control device 11 via a deflection device 10 . The mechanical control device 11 consists, for example, of a bolt, a rod or the like, which is preferably mounted or guided horizontally in the passive leaf 5 and is provided with a roller at its free end, as will be described below. At the one or more push rods 8 a, 8 b associated with the control device 11 each with egg ner roller 13 , 14 , each roller against an inclined surface 15 , 16 is in contact or can be brought into contact, which in turn on the the deflection device 10 associated end of each push rod 8 a, 8 b is formed. When the control device 11 moves in the direction of an arrow 18 , the control device or the bolt representing the control device 11 is moved out of the standing wing 5 in the horizontal direction, which results in a movement of the push rod 8 a in the vertical direction downward or a movement of the push rod 8 b in the vertical direction has the consequence that the locking bolts 20 seated at the end of each push rod 8 a, 8 b are moved back into a release position in which they are out of engagement with the relevant door frame. In this state, the passive leaf 5 can be opened, provided that the active leaf 4 is also opened, as will be described below.

In the opposite case, that is, with the inactive leaf 5 and the closed active leaf 4 , the control device 11 moves in opposite directions in the direction of arrow 18 into the inactive leaf 5 , as a result of the corresponding horizontal movement of the rollers 13 , 14 in the direction opposite to the arrow, the push rods 8 a, 8 b are extended upwards or downwards and lock the inactive leaf 5 with respect to the door frame or the like.

The rollers 13 , 14 are firmly connected to the control device 11 , ie they are located, for example, on a plate 11 a and are moved together with the control device 11 or the control pin in the horizontal direction in FIG. 2. The rollers 13 , 14 are preferably rotatably supported vertically one above the other on the plate 11 a. The rollers 13 , 14 are located in a plane parallel to the plane of the passive leaf 5 , as can be seen from FIGS. 1 and 2.

The push rod 8 a and / or the push rod 8 b are each biased by a spring device 22 , 23 , namely the push rod 8 a in the vertical direction downwards or the push rod 8 b in the vertical direction upwards, ie in each case in the unlocked state, so that after opening the active leaf 4, the push rod 8 a and / or the push rod 8 b by this spring bias performs a movement in each case in the unlocked state, with the result that the control device 11 is displaced in the direction of arrow 18 . This shift of the control device 11 in the direction of arrow 18 can obviously only take place when the active leaf 11 is stored out of the position shown in FIG. 2 out in the open position and thus a trained on the control device 11 wheel, roller 24 or The like comes out of engagement with a stop 25 which is arranged on the active leaf 4 .

1 in accordance with the stop 25 has Fig. The form of a vertical bar or a strip portion with a chamfered surface 26. In the state shown in Fig. 1, in which active and passive wings 4 , 5 are closed, the roller 24 is pressed into a position located within the wing 5 , so that the push rod 8 a and 8 b in their locked state up or down due to the effect of the order steering device 10 is shifted. After a slight opening of the active leaf 4 , the control device 11 is gradually pushed out of the passive leaf, since the roller 24 runs with the opening of the active leaf 4 over the inclined surface 26 ( FIG. 1). The displacement of the control device 11 or the relevant rod from the passive leaf 5 is supported by a spring preload, which is arranged in or around the Steuereinrich device 11 and presses the roller 24 out of the stationary wing 5 .

From Fig. 1 and Fig. 2 it can be seen that the control device 11 , the deflection device 10 and the push rod 8 a and / or the push rod 8 b are arranged within the passive leaf 5 , so that a horizontal movement of the control device 11 in a vertical movement of the push rod 8 a and / or 8 b is trans fer, wherein between the push rod 8 a and 8 b and the control device 11, an angle of 90 ° is preferably held.

The rollers 13 , 14 are defined by a substantially horizontal axis of rotation and are in a common with the push rod 8 a and 8 b common plane, while the axis of rotation of the roller 24 is defined by a vertical axis.

The biasing the control device 11 causing spring device is designated in Figs. 1 and 2 with 27 and acts in the direction of arrow 18th

In the door shown in FIG. 1, the push rod 8 a or 8 b is preferably in a parallel arrangement to the push rod 1 . The movement of the push rod 1 is not in connection with the movement of the push rod 8 a or 8 b, but rather who operated the push rods 1 and 8 a or 8 b independently and, for example, with a time delay. In the event of panic, the push rod 1 is first shifted into an unlocking position for the purpose of opening the latches 2 , 3 , 3 a by actuating a panic lever (not shown), whereupon the active leaf 4 can then be opened. Only then can the inactive leaf 5 be opened due to the unlocking and the movement of the push rods 8 a, 8 b and the control device 11 analogous to the direction of the arrow 18 .

From Fig. 2b it can further be seen that the push rods 8 a and 8 b have vertical guide slots 30 , 31 and 32 , 33 , within which guide pins 35 , 36 and 37 , 38 are provided, which are on the passive leaf 5 in the horizontal direction stand stationary and limit the movement of the push rod 8 a or 8 b between the unlocked position and the locked position. To bias the push rod 8 a in Fig. 2b in an upward direction, the spring device 22 is attached at its lower end in Fig. 2a to the push rod 8 a and fixed at its upper end ren fixed to the passive leaf, so that the voltage before acts on the push rod 8 a in an upward direction, while the spring device 23 ( Fig. 2a) has an opposite arrangement in order to prestress the given upper push rod 8 b in one direction vertically downward. The spring devices 22 , 23 and 27 thus cause a displacement of the entire locking device into the unlocking position after release of the control device 11 by the active leaf 4th

The spring device 22 and 23 can also preferably be attached centrally to the push rod 8 a and 8 b.

On the spring 18 devices 22 and 23 can be omitted with a sufficiently large spring force of the spring.

According to a modification of the invention, the fixed leaf 5 has either only one push rod 8 a or one push rod 8 b, ie the locking device acts either only upwards or downwards compared to the door frame not shown in FIG. 1.

Fig. 3 shows a further modified embodiment of the device according to the invention.

In the embodiment according to FIG. 3, the passive leaf 5 is provided with a control device 11 a located in its upper region, which cooperates via a roller 26 with a stop 25 or the like formed on the active leaf 4 when the passive leaf 5 and the active leaf 4 are closed . In this case, the control device 11 a, which is preferably displaceable in the horizontal direction, presses a roller 40 onto a locking device 41 , the roller 40 causing the deflection between the control device 11 and the locking device 41 and the control device 11 a with a device according to FIG . 3 FLAE oblique surface 42 is provided, along which the roller 40 slides. In the locking position, the lock 41 , for example in the form of a bolt, is displaced upwards and the rod-shaped control device 11 a is displaced into the passive leaf 5 when the roller 26 is in contact with the stop 25 . If, however, the active leaf 4 is opened, the CONT drives ereinrichtung 11 a of the stationary wing in the horizontal direction and 3, the locking bolt 41 moves in Fig. Ver tical down is taken whereby the unlocking position.

In the embodiment of FIG. 3 Federeinrichtun conditions 27 and 22 are provided to bias the control device 11 a in a direction that causes their displacement from the stand wing 5 out, the spring device 22 Ver locking bolts of the locking 41 in their unlocking positions tion preloaded.

The device described in connection with FIG. 3 can either be provided in the upper area of the passive leaf, reversed kinematically in the lower area of the passive leaf or both above and below.

Fig. 4 shows a further modification of the device according to the invention. In the embodiment according to FIG. 4, the device consists of a bolt denoted by 41 , which represents the locking device Ver, with a spring device 22 for pretensioning the bolt 41 , a rotatably mounted lever or a rocker 44 , for example in the middle by a Bearing pin 45 is rotatably mounted relative to the passive leaf 5 . The lever or the rocker 44 has a roller 48 or 49 at each of its two ends, the roller 48 being in contact with the lower part of the bolt 41 and the roller 49 being in contact with one end 50 of a bolt 51 , when the latch 51 occupies the position in Fig. 4 which is excellent. The bolt 51 can, for example, correspond to the bolt 2 or 3 , 3 a according to FIG. 1 and is displaced by, for example, the push rod labeled 1 in FIG. 1.

In the embodiment shown in FIG. 4, the lever or the rocker 44 is thus rotated in the locking position of the bolt 51 into the position in which the locking device, represented by the locking bolt 41 , is pressed into its locking position. When unlocking the bolt 51 , the lever 44 is shifted, for example, clockwise by the force of the spring 22 and the locking device 41 is unlocked.

The mirror symmetric up or down possible Ver locking is provided when the doors are a so-called burglar-resistant property. Is the break in inhibiting property not required, the locking can either be provided only upwards or only downwards.

FIGS. 5 and 6 show a further modification of the device OF INVENTION to the invention. Fig. 5 is a horizontal section showing the active leaf 4 and the stationary wing 5. The inactive leaf 5 contains a control device 60 , which will be explained in connection with FIG. 6. Referring to FIG. 6 is a ADJUSTABLE rer lever 61 is provided which is firmly connected to a bolt or the like, which is designated 62, wherein the pin is mounted rotatable about a fixed axis of rotation 62. The lever 61, which extends out from the fixed leaf in the open state of the Gehflü gels is displaced by the plant at the active leaf 4 from the fully excellent in Fig. 6 position to the ge in Fig. 6 dashed lines shown position, whereby the bolt 62 in Fig. 6 is turned counterclockwise. Due to the rotation of the bolt 62 , which is cut obliquely at its end, a bolt 62, which is also assigned an obliquely cut counter pin 63 , is displaced in the direction of an arrow 64 , with the result that a pin in FIG. 5 and FIG. 6 not shown mechanism of the inactive leaf 5 is locked. This means that the passive leaf 5 , when the bolt 62 holds the lever 61 in the position shown in dashed lines in FIG. 6, the passive leaf 5 is locked, while after opening the active leaf 4 the bolt 61 by the action of a spring 65 or by other means is rotated clockwise in Fig. 6. The counter pin 63 is displaced by the spring 65 in the direction opposite to the arrow 64 , which results in the rotation of the pin 62 together with the lever 61 in the position shown in FIG. 6 which is fully excellent.
