Description

The present invention relates to a door fitting for a panic door lock, with an actuating rod for actuating the panic door lock, wherein the actuating rod is pivotally mounted by means of pivoting levers about an actuating axis. Moreover, the present invention relates to a panic door lock for a door leaf of an escape door, in particular for single-leaf and / or double-leaf doors.

Panic door locks and door fittings for a panic door lock are known from the prior art, for example DE 89 00 679 U1 or DE 10 2005 037 041 A1 , Such Paniktürverschlüsse serve to operate doors, especially escape doors, in case of panic.

When designing panic door closures, regulations must be observed which define the maximum permissible actuating forces for a door lock as a function of various load cases (door loads or unloaded), in particular DIN EN1125. The actuating forces acting on a door lock are influenced by its transmission components. Since a door lock can be constructed with various transmission components, e.g. By means of a modular system, can be achieved due to the different constellations consistent operating forces only by adjusting these components. This is associated with considerable effort, for example. In the context of construction.

The invention has for its object to enable with simple structural means in Paniktürverschlüssen constant actuation forces.

The invention solves the above object by a door fitting with the features of claim 1. Thereafter, the door fitting is characterized by the fact that the pivot lever are designed to be adjustable in length.

Such a configuration has the advantage that the length of the lever arm of the actuating rod can be easily adapted and adapted to the respective (panic) door lock. Due to the adjustable length of the pivot lever of the actuating rod system-related dispersion of the operating forces can be compensated. This makes it possible in a simple manner to adapt the door fitting and thus the panic door lock to changing requirements. For example, an extension of the pivot lever (extension of the lever arm of the actuating rod) causes the torque acting on a mortise lock, for example, on a lock nut of a mortise lock is increased without the operating force on the confirmation bar increases. If the operating conditions at the panic door lock change, this can be responded to by adjusting the door fitting in a simple manner. Operating forces can thus be reduced, so that an operation by children and / or older people is possible. Barrier-poor or barrier-free embodiments can be achieved.

In the operating rod, which can also be referred to as a "bar handle", it is an operating element which is mounted in the installed position at least approximately horizontally (horizontal actuating rod).

The actuating rod is pivotally mounted by means of pivoting levers about an actuating axis of the door fitting, in particular on a bearing which forms part of the door fitting. The actuating axis can be aligned parallel to the actuating rod. The storage may have bearing blocks. On the bearing blocks each one facing away from the actuating rod end of the pivot lever can be rotatably mounted. At the back of the bearing blocks, the door fitting can be mounted on a door leaf (mounting side).

Specifically, the actuating rod can be arranged via the pivot lever for an operative connection with a mortise lock, in particular by means of a transmission. The transmission can be arranged on the mounting of the door fitting. Thus, the mortise lock, in particular a lock nut of the mortise lock, can be actuated by means of the actuating rod.

Advantageously, the pivot lever may be formed telescopic. This creates a structurally simple and at the same time stable possibility of length adjustment.

In concrete terms, the pivot lever can each have a plurality of sections which are displaceably guided in the longitudinal direction of the pivot lever against each other.

There may be provided a guide element, on or in which the sections of the pivot lever are guided displaceably. The guide element may, for example, be designed as a sleeve, on or in which a first section and a second section of the pivot lever are displaceably guided. The first portion may face the actuating rod and the second portion may face the bearing. The first portion and the second portion may each be dimensioned in diameter so that they can be inserted not only in the guide element, but also in each other. This is a particularly large adjustment realized. It is also conceivable that the pivot lever each having an inner portion and an outer portion, in which the inner portion is guided displaceably.

In an advantageous manner, the pivot levers can be set up for stepped length adjustment. This allows a targeted length adjustment in defined and reproducible steps on both pivot levers. For this purpose, appropriate steps may be provided, for example. A detent, perforation or the like.

Alternatively, the pivot lever may be arranged for stepless length adjustment. This is a particularly fine, namely stepless adjustment of the length of the pivot lever allows. For this purpose, a sliding guide be provided, which is set up for stepless length adjustment.

In an expedient manner, the pivot levers may each have a locking element for determining a set length. This can be a fixed adjustment of the swing lever length fix. The locking element can be designed such that a repeated release and locking of the locking element is possible. The locking element can interact positively or non-positively with the pivot lever or portions of the pivot lever. In concrete terms, the locking element can be designed as a pin engaging in a hole or acting on the pivot lever or a pivot lever portion screw.

Advantageously, the locking element can be concealed on or arranged in the pivot lever. As a result, the adjustability for unauthorized persons is not recognizable. The locking element can be arranged in the interior of the pivot lever, for example. Upon actuation of the locking element by an electromechanical actuator. The locking element can also be arranged so that it is outside the field of view of a passer of the door lock, e.g. on the side of the pivot lever facing a door leaf.

Conveniently, the locking element can be set up such that it can only be actuated by authorized persons. Thus, the risk of manipulation is minimized because even if unauthorized persons recognize the locking element, no settings can be made. In particular, the locking element by a lock (profile cylinder or padlock), or an electronic authorization be assured. It is also conceivable that the locking element is designed as a coded screw which can only be actuated with a correspondingly coded key.

The object mentioned above is also achieved by a panic door lock with the features of the independent claim. With regard to the achievable advantages, reference is made to the comments on the door fitting.

For further embodiment of the panic door lock, the measures described in connection with the door fitting can serve.
