"Lock for panic doors"

The invention relates to a lock for double-leaf panic doors, one of which has a wing over its upper and upper Has lower edge protruding latches or bolts with connecting rods ending in a lock case or an opposing case can be locked in and out, the connecting rods having a panic handle arranged on the inside of the sash are actuatable.

Such locks can be opened from the outside of the door with a handle and / or key. From the inside of the door, the lock can be opened with a finger grip or a panic bar fastened in it, which only needs to be swiveled by the people pushing against the door, usually in the direction of the door or the wing to enclose latches or bolts on the face of the sash as well as on the top and bottom of the sash and thus open the door. If it is a double-leaf panic door, then

7703362 2i.iS.77

each wing has a panic handle or a panic bar attached to it. The so-called Gohfiügel, which is used in normal through traffic, has a lock case with a latch and / or bolt, which engage in a counter case j of the other wing, which can be locked on its upper and lower side. The counter box also has; a mechanism with triggers which, when the panic handle of this wing is operated, push the latch or bolt of the pedestrian wing back into their lock case so that both wings can swing open.

Often no door sills are arranged in the area of panic doors, and the doors or their leaves extend directly above the floor. Since the latches or bolts assigned to the connecting rods are held in a locked position under the action of a peder _? they would drag across the floor or pressed against the floor when opening and closing the wing in question, as well as in the open position of the wing, if they are not kept in the locked state by operating the drive rods or holding down the panic handle. In the event of a panic, however, it cannot be expected that the panic handle in question will be held down during the entire opening process of the door. This can lead to considerable resistance when opening this wing and obstruct the escape through the panic door. In addition, dragging the trap or bolt across the floor results in undesirable damage to the floor.

It is known to avoid these disadvantages in that ia panic handle springs are arranged which hold down the panic handle after actuation . The functionality of this arrangement presupposes that the panic handle, among other things, is pivoted a ventilated amount so that the springs can be effective. If the pivoting is insufficient, the panic

grabbed it, which can be enough to enclose companies or bars, the panic handle swivels back into its rest position and the latch or bolt lock out. Often leads Such an arrangement also leads to greater opposing forces when the panic handle is actuated.

The object of the invention is to open the panic Ensure door without appreciable resistance.

This object is achieved in that at least one resilient detent for engagement in the lock case or in the counter case into associated latching recesses on at least one drive rod when the latches or bolts are locked is arranged and that a trigger acting on the detent against the action of the spring is provided.

This ensures that when the panic handle is actuated and the associated connecting rods are locked in therewith Fall or latch these are held by the catch as soon as they are. have reached a position that a opening of the wing in question without appreciable resistance. The actuation of the panic handle is thereby not impaired at all, in particular not made more difficult because the spring for the detent is proportionate may be weak. In any case, it ensures that the movement of the wing in question does not more obstructed after the latches or bolts are included to such an extent that the wing can be opened.

It is useful if the detent is a detent arranged on a detent plate, and the detent is in the detent position pressing spring engages the locking plate. Such a locking plate can also be relatively narrow

'Can easily accommodate lock cases or counter cases.

The pivotable locking plate in its plane can be a bend as an abutment for one from the lock case or have released release pin from the counter box. In particular, the release pin can be passed through the faceplate and essentially with the locking plate be inextricably linked. By simply pressing the release pin, the locking lug is released from the assigned one East recess lifted out, and the connecting rods are hers There are no latches or bolts. When the trigger pin is passed through the faceplate and protrudes over it, can, for example, through a suitable incline Contact surface on the opposite lock case or counter case can also be achieved that the latches or latches actuated by the connecting rods automatically when Closing the wings can be excluded.

\ In the area of the lock case or the counter case,

the connecting rods can be designed in various ways, the locking recesses being arranged on the edge of the plate.

In the following the invention is explained with reference to an embodiment shown in the drawing; it show:

Fig. 1 is a side view of an open counter box of a double-leaf panic door when the door is closed Wing, i.e. excluded trap on the upper or Underside of the wing,

FIG. 2 shows the object of FIG. 1 with the trap enclosed.

7703362 05/26/77

The counter box 1 shown in the figures has a faceplate 2, which sits on the associated narrow side of the door leaf closes. In the other door leaf, a lock case (not shown) is arranged which, when the door leaves are closed, is opposite the counter case and its latch or bolt in assigned openings 3 or 4 engage the faceplate 2. The counter case 1 can be displaced in a known manner against the latch or the bolt of the lock case in the area of the openings 3 and 4 push back.

In addition, the upper drive plate 7 and a lower drive plate θ are arranged in the crossbar, which are trelbstangen (not shown), which extend through the door leaf to its upper and lower edge and there an I ¹ slIe or a ri * gel carry »which protrude in excluded state over the relevant pages.

A drive pulley 9 arranged between the two triggers 5 »6 has, for example, a kiss 10 and can thereby be operated» ie rotated «with the aid of a panic handle (not shown) , in which pins 13 »14 attached to the drive plates 7» 8 are guided. As can be seen from a comparison of FIGS. 1 and 2, by rotating the drive pulley 9, the drive plates 7 »8 with their associated drive rods and latches or bolts are enclosed. At the same time, the triggers 5, 6, each having a pin 16 guided in an inclined slot 15, are pressed against the latch or the bolt of the lock case and transport them back into the lock case.

.6- I

To prevent the trap connected to the lower drive plate 8 from dragging across the floor in panic XaIl after releasing the panic grip ynä thereby preventing the opening of the sash, the drive plate 8 has two locking recesses 18 arranged one behind the other on its edge 17 opposite the faceplate 2, 19, in which a detent 20 engages as soon as the drive plate 8 is raised so far that the associated case can no longer hinder the pivoting movement of the door leaf. The locking lug 20 consists of a bending of a locking plate 21, which is pivotably mounted at 22 in the retainer 1 against the action of a spring 23 which is mounted on the inftA guide cup 24 for the lower drive plate θ «

The free end of the spring 23 is supported on a bend 25 of the locking plate 21, which also carries a release pin 26 on the same side, which is held in the bend 25 in an essentially inviolable manner and is passed through the faceplate 2.

When the mechanism of the counter box is brought into the position shown in FIG. 2 by pressing the panic handle has been, whereDei the locking lug 20 engages in one of the locking recesses 18 or 19 and the drive plates 7 »8 with their Associated traps holds in the locked state, the state shown in Fig. 1 can be simple Restore the pressure on the release pin 26. The release pin 26 will generally only be actuated when the door leaf in question has been pivoted back into its closed position, so that then the latches or bolts connected to the drive plates 7, 8 directly in can enclose their associated recesses on the floor or on the upper frame part of the door.
