Description

Push rod with tensioning device

The present invention relates to a push rod device for actuating a door lock in a door. The door is preferably a panic door, i. H. a door in an escape and rescue route. The door has a door leaf movably mounted in a fixed door frame and the door lock is mounted in or on the door leaf,

full

a U-shaped basic profile (22) which can be fastened to the door leaf (16),

a manually operable U-shaped pressure profile (28), wherein the base profile (22) and the pressure profile (28) are inserted into each other via their respective open side and the pressure profile (28) is movable relative to the base profile (22),

a transmission system (30) arranged between the base profile (22) and the pressure profile (28), which converts a movement of the pressure profile (28) into a movement for actuating the door lock (18) by the

Transmission system (30) arranged on one in the pressure profile (28)

Receiving device (32) is coupled. Under panic doors to be understood in connection with the present application doors, located in escape and rescue routes of

Buildings are located. Normally, the panic doors are closed,

for example, for sound insulation and insulation purposes. Panic doors can also be designed as fire protection closures. It is necessary to keep such panic doors closed to prevent the spread of a fire as long as possible. In the case of a dangerous situation, however, the panic doors have to be opened quickly and reliably in a simple manner. For this panic doors can be provided with push rod devices that extend in a horizontal arrangement on the door over a large part or even over the entire width of the door and thus provide a very easy panic case way to open the door lock and thus the panic door. To open the panic door, a user presses the pressure profile in the direction of

Door leaf into the basic profile telescopically inside. The transmission system converts the movement of the pressure profile into a rotary movement with which the door lock connected via a connecting nut is opened.

To ensure the trouble-free operation of the push rod device, it is necessary to provide a reliable and reliable connection between the pressure profile and the transmission system or the receiving device of the transmission system. In conventional push rod devices, the relevant parts of the transmission system are clipped to the pressure profile, so that the pressure profile is a connection point for providing the

Must have clip connection, to which the relevant part of the

Gear system can be clipped. The junction is formed in known pressure profiles in the form of rails with undercut, which are arranged at the bottom of the pressure profile and over the entire Extend pressure profile. To provide the rails, the pressure profiles are usually extruded or extruded, but has the disadvantage that the choice of material for the pressure profiles is limited and the corresponding manufacturing processes are relatively expensive. Furthermore, in conventional push rod devices, the pressure profiles must have a certain material thickness, so that no metal sheets can be processed.

DE 20 2009 009 609 U1 describes a push rod device in which the receiving device is fastened to the pressure profile on the bottom side with a joining connection. In addition to the fact that the production of

Joining joints in comparison to Klipsverbindungen is relatively expensive, especially when using sheets with a small

Material thickness, the joints also visible on the opposite side of the pressure profile of the joint. This page is the one that an observer is looking at, so that the push rod device produced in this way does not give an optically positive impression. To improve the visual impression, this page must be reworked, which is associated with costs and effort. Object of the present invention is therefore to provide a push rod device, which overcomes the disadvantages of the prior art and in particular allows the processing of sheets with low material thickness cost and gives a visually positive impression.

It should also include the case that the receiving device is indirectly or indirectly attached via the U-bracket device on the pressure profile, so has no direct contact with the pressure profile. In this case, the connection between the U-bracket device and the receiving device can be realized in any suitable manner. For this purpose, for example, a joint connection can be used, which in this case but not on

Pressure profile must be arranged and thus has no effect on the visual impression of the pressure profile. One-piece designs,

preferably made of plastic, are possible. The U-bracket device is connected to the Verspannmitteleinrichtung at their free ends against the

Projection device of the pressure profile pressed so that it is thus secured by a positive and frictional engagement on the pressure profile. The
