EP3034726B1 - Counter lock of an espagnolette lock - Google Patents

Description

The invention relates to a counter lock of an espagnolette lock for a two-leaf door, with a Fallenaushub, which is guided by a recess in a face plate extendable and driven by a nut, the Fallenaushub has different width sections and the recess the Fallenaushub only at some of the sections leads.

In such an espagnolette lock the counter lock is mounted in a passive wing, a so-called passive wing. The main lock is arranged in an active wing, a so-called active wing. By operating the counter nut the latch excavation of the counter lock is moved against a case of the main lock and released the locking of the two wings.

Such a counter lock is for example from the DE 10 2013 100 275 A1 known. In this counter lock a latch excavation has much smaller dimensions than a recess for a case of the main lock. The trap excavation has a contour adapted to the recess with a central constriction.

A main lock with a counter lock of a two-winged door is for example from the EP 2 703 583 A2 known. In the counter lock the latch excavation is designed as a rectangular plate.

Furthermore, from the EP 2 752 539 A1 a counter lock known in which the trap excavation an adapter can be placed.

A disadvantage of the known espagnolette locks is that a case of the main lock can jam in the depression by means of the Fallenaushubs the counter lock. Usually a case head today's traps has a narrow protruding edge, which can hook between the Trap excavation and the recess leading recess in the faceplate. This is especially true when the wings are pressed in a movement with the depression of the trap.

The invention is based on the problem, so far as to form a counter lock of the type mentioned that a hooking of the trap is reliably prevented at the Fallenaushub.

This problem is inventively achieved in that the Fallenaushub is wider outside of the region of the guide portion than in the region of the guide portion and that, in the depression of the case of the main lock by means of the Fallenaushubs, the Fallenaushub projects beyond the protruding edge of the trap with its wide section.

By this design, the guide is separated from the outer edge of the Fallenaushubs. This makes it easy to ensure that the trap excavation is reliably located in front of the trap and in particular the narrow protruding edge of the trap can not get into a gap between Trap excavation and recess. The trap excavation towers above the protruding edge of the trap with its wide section. This reliably prevents entanglement of the trap on the trap excavation. The outer edge of the latch excavation is according to the invention spaced from the guide section, because the latch excavation is wider outside the region of the guide section than in the region of the guide section. Thus, the trailing edge of the trap over the trap excavation can slide over the guide portion along the wide area of the trap excavation.

The leadership of the Fallenaushubs designed according to another advantageous embodiment of the invention is particularly simple if the recess of the faceplate has a guide portion for guiding the Fallenaushubs.

Outside the guide section, catching of the latch according to another advantageous development of the invention can be reliably prevented if the recess of the faceplate outside the guide section has an edge spaced from the latch excavation. This distance between the edge of the recess and the trap excavation should be greater than the width of the protruding edge of the trap.

The Fallenaushub designed according to another advantageous embodiment of the invention particularly constructive easy if the trap excavation has a constriction with continuous change in width.

According to another advantageous embodiment of the invention, outside of the region of the guide section, the trap can be designed almost as wide as the trap excavation has projecting ribs for producing the sections of different widths. This can ensure that the entire contact of the trap with the counter lock when moving out of the Fallenaushubs on the Fallenaushub. For a contact of the case with the faceplate of the counter lock and thus snagging is particularly reliable prevented.

FIG. 1 shows a two-leaf door with a frame 1, in which a leaf 2 and a stationary leaf 3 are pivotally mounted. The active leaf 2 and the inactive leaf 3 can be locked with a drive rod lock 4 in the frame 1. The espagnolette lock 4 has a main wing 5 arranged in the moving leaf 2 and a counter lock 6 arranged in the fixed leaf 3. The main lock 5 has a handle 7 for unlocking. The counter lock 6 also has a handle 8 for its own unlocking and simultaneous unlocking of the main lock 5. The main lock 5 and the counter lock 6 control further not shown secondary locks 9, 10 at.

FIG. 2 shows in an enlarged view of the main lock 5 and the counter-lock 6, that a bolt 11 and a latch 12 are arranged in the main lock 5 and penetrate into the counter lock 6 in the illustrated locking position. For clarity, in FIG. 2 the limitations of the active leaf 2 and 3 fixed leaf indicated. The main lock 5 has a driver 13 of a lock cylinder, not shown, and a nut 14. The nut 14 is connected to the in FIG. 1 coupled handle 7 coupled.

Furthermore, the counter lock 6 has a Riegelaushub 15 and a Fallenaushub 16, which are coupled to a nut 17 in the counter lock 6. The nut 17 of the counter lock 6 can be from the in FIG. 1 drive shown 8 drive. When driving the nut 17 of the counter lock 6, the latch 12 and the latch 11 of the main lock 5 are pushed out of the range of motion of the passive leaf 3 by means of the latch removal 16 and the latch lifting 15.

FIG. 3 shows a plan view of the Fallenaushub 16 having portion of the counter lock 6 from FIG. 2 seen from the side of the main lock 5. The counter lock 6 has a fixed in the inactive leaf 3 faceplate 18 with a recess 19 for carrying out the Fallenaushubs 16. The Fallenaushub 16 has different width sections 20, 21. The recess 19 has a guide portion 22, which leads a narrow portion 20 of the Fallenaushubs 16 , Outside the guide section 22, a trailing edge 16 facing edge 23 of the recess 19 is spaced from the Fallenaushub 16. The trap excavation 16 has ribs 24 projecting to produce the wide sections 21.

FIG. 4 shows a further embodiment of a Fallenaushubs 25 with adjacent areas of a faceplate 26. The faceplate 26 has a recess 27 for performing the Fallenaushubs 25. The Fallenaushub 25 has a constriction 28 in a central region 28 to produce different widths sections 29, 30. A guide portion 31 the faceplate 26 guides the trap excavation 25 in the narrow region 29 with the constriction 28. At its ends where the trap excavation 25 has its wide sections 30, an edge 32 of the recess 27 is spaced from the trap excavation 25.
