Description

The invention relates to a double-leaf door, Consists of an active and an inactive leaf, each of which is one in its dimensions with the other has matching and opposite each other at the same high point pocket, with a Latch-bolt mortise lock arranged on the active leaf and with one arranged on the passive leaf Espagnolette lock for the actuation of espagnolette rods, which are located in a close to the fold, from top to bottom are housed below the continuous guide channel. This guide channel is used for wooden doors regularly formed by a continuously milled groove, then covered by a glue strip, while in the case of steel doors, corresponding guide tubes are usually used for this.

Double-leaf doors of the above type are z. B. according to US-PS 13 46 670 or DE-OS 26 11 359 known. Ever according to the instructions for use and the nature of the locks to be inserted in the pockets such doors as fire protection doors, as escape doors with panic function or also as simple closing doors can be used. These various uses put the door manufacturer in front of the Problem that he has a variety of the respective purpose prepared door leaves must manufacture and provide. Since that is an economic one industrial production made difficult, the door operators limit themselves to a high-turnover to produce double-leaf door design on a hinge or in series and all other designs in each case to be made as individual pieces or to have them changed accordingly afterwards. Such custom orders but are quite expensive and because of the fact that such products are made to order, they also take a long time Delivery times are documented Often such double-leaf doors, which are primarily used for fire protection closures have been tested with proof of function with regard to their fire resistance and long-term function, then no longer permitted if a structural change is subsequently made to the door leaf, for example a corresponding weakening of the Türblattcs is made. This means that there can be corresponding overlaps the relevant door requirements come, for example, in the event that the door system the demands of a supervisory authority should primarily serve as a panic emergency exit door, on the other hand another authority requires fire protection as a priority. A subsequent conversion of the often already Doors installed at the place of use are then very complex and associated with high costs. Also must then often the corresponding approval label on the double-leaf door must also be removed.

The invention is therefore based on the object of creating a double-leaf door, the wing with regard to their factory-made prefabricated pockets are designed so that depending on the occurring Possible uses and, depending on the desired function, the most varied of locks or locks. Key elements can optionally be accommodated

jo nen without the need for subsequent modifications or recesses need to be made on the door leaves, i.e. the passive and active leaves in just one standard design can be manufactured industrially. This task is based on a double-leaf door of the type mentioned at the outset solved according to the invention in that in the passive leaf Above the tuck-in flap, which is at the same height as the one-corner pocket on the pedestrian wing, another tuck-in pocket is provided for Wahlweiscn receiving the shoot bolt lock, which is also in its dimensions coincides with the other two, and that the two pockets on the Standflügcl through Blind cuffs can be covered. In this way, the espagnolette lock to be accommodated in the inactive leaf can be used either in the lower or upper leak tab, while the one that is not required Insert pocket can be covered by a blind cuff, which is expedient in its dimensions corresponds to the assigned mortise lock cuff. With the shoot bolt lock in a high position can also be inserted into the lower pocket of the inactive leaf if necessary, but also with the lower one Driving rod to be connected driver bracket with a latch insertion cam and a bolt locking cam are used, which interact with the latch or the bolt of the mortise lock on the pedestrian wing. In the latter case, a panic lock with two can also be installed in the lower pocket Locking holes and the triggering devices to be swiveled into them

bo lever for the interacting trap and the Bolt of the Gchflügcl mortise lock can be used.

In the stationary wing, in the area of the two pocket bags Door leaf perforations for the actuation

h ") gan of the drive-bolt lock can be provided, if necessary can be covered by blind contacts.

In the drawing are an advantageous embodiment the double-leaf door according to the invention as well

some lock equipment for the most part shown schematically

F i g. 1 is a plan view of the double-leaf door, while the

F i g. 2 to 5 show the most varied of lock equipment.

The in F i g. 1, the double-leaf door shown has an active leaf 1 and an inactive leaf 2, which are attached to the door frame 5 via the pivot bearings 3, 4. Both door leaves can be made of wood, plastic or steel ίο. In the pedestrian wing 1 is a plug-in pocket 6 for receiving a latch-bolt mortise lock at the usual height above the ground. In contrast, there are two such insertion pockets 7, 8 in the inactive leaf 2, which are suitable for the optional accommodation of a espagnolette lock, the espagnolette rods of which are to be accommodated in a guide channel 9 which is located close to the fold and runs continuously from top to bottom. All three Einleckaschen 6, 7 and 8 have the same dimensions, in particular according to the DIN standard 18 250 part 1. While the pockets 6, 8 have a usual lock nut-bottom distance a of 1050 mm, the upper pocket 7 on the inactive leaf 2 a distance b of 1500 mm. In the upper inactive leaf corner, a further recess 10 is provided as an extension of the guide channel 9, which is used to accommodate a espagnolette lock.

The two door leaves or leaves 1, 2, including their dimensions, are identical Insert pockets 6, 7 and 8 as well as the corner recess 10 and the guide channel in the inactive leaf 9 factory-made, to then on the Einbaustcllc with the respective desired there, the respective To be able to provide lock equipment in accordance with building and official regulations. Included It is essential that the two door leaves, in particular also the passive leaf 2, no subsequent modifications or even need to experience weaknesses, especially for any Fcuerschutziüren and the The relevant safety requirements of Importantkeil is.

In the case of FIG. 2 and 3 is in the pocket 6 in Active leaf t a conventional latch-bolt mortise lock ti used, while the passive leaf 2 with einin conventional shoot bolt lock 12 is provided, the two in the guide channel via the Beläligungsgriff 12 ' accommodated drive bar rods 13,14 to adjust in opposite directions, with the outer End of the espagnolette rods in corresponding locking openings can move in or out of the door frame or door base. If the corner recesses 10 in Inactive leaves 2 are not required, they are covered by right-angled blind faceplates 15.

In the case of FIG. 2, the espagnolette lock 12 is inserted into the upper pocket 7. In the lower insertion pocket 8 there is accommodated a driver bracket 16 which is firmly connected to the lower drive bolt angle 14 and which has a latch insertion cam 16 'and a bolt locking cam 16 "'of the gehflügelseitig arranged trap Ricgel-Kinsteeksehlosses II. so that when completed Gchflügel I dasTrcibricgelsehloU 12 is not opened advertising b ^r> the kiinn. Rather, the drive bolt angles 13, 14 can only be retracted in the locked position of the lock bolt II '. At the same time, the latch 11 ″ is pushed back by the latch insertion cam 16 ', so that no damage whatsoever can occur to the lock latch 11 ″ or to its lock hole opening in the cuff 17 covering the insert pocket 8 on the stationary leaf 2 when the passive leaf 2 is subsequently pushed open. The bolt locking cam 16 ″ is in the retracted position of the drive rod lock in front of the enclosed lock bolt 11 ', which ensures that the active leaf 1 can only be locked when the passive leaf 2 is locked.

In the case of FIG. 3 is the bolt lock 12 in the lower insert pocket 8 inserted, while the upper insert pocket 7, which is then not required, is replaced by a blind cuff 18 is covered, which has the same dimensions as the cuff of the espagnolette lock and the pedestrian wing Mortise lock owns.

The in the F i g. 4 and 5 illustrated lock equipment of the double-leaf door differs from that described above in that a bolt-latch mortise lock 22 is inserted here in the insertion pocket 6 on the side of the mound with panic function and in one of the two insertion pockets 7 or 8 of the inactive leaf, a espagnolette lock 23 is housed with panic function. In the case of FIG. 5 the shoot bolt lock 23 is inserted into the lower pocket 8 It is with two in the locking holes for the The latch and the bolt of the mortise lock on the active leaf are provided with pivoting release levers, about the latch 22 'and the bolt 22 "of the bolt-latch mortise lock when the drive bolt handle 24 is actuated 22 must be pushed back. The insertion pocket 7 is covered by the blind cuff 18. In case of Fig. 4 is the bolt lock 23 'in the upper pocket 7 inserted, while in the lower pocket 8 one with two corresponding release levers equipped panic lock 25 is housed. Its release levers are with the lower drive bar 14 drivingly connected so that they pivot into the corresponding locking holes when they are retracted and thereby push back the latch 22 'and the bolt 22 "of the bolt-latch mortise lock 22.
