Abstract: A guide rail device for laterally guiding a rolling door or rolling grille armor of a rolling door or rolling grille includes a guide rail for vertically guiding the rolling door or rolling grille armor, an infeed funnel for guiding the rolling door or rolling grille armor into an entry area of the guide rail, with the infeed funnel being movable relative to the guide rail, and a damping body connected to the infeed funnel which dampens vibrations and shocks of the infeed funnel. Further, a rolling door or rolling grille includes a first guide rail device and a second guide rail device. In particular, the guide rail of the first guide rail device is fixed laterally on the building opening, and the guide rail of the second guide rail device is fixed laterally on the opposite side of the building opening.

Abstract: The invention provides a guide rail device (10) for laterally guiding a rolling door or rolling grille armor (68) of a rolling door or rolling grille (11), comprising a guide rail (12) for vertically guiding the rolling door or rolling grille armor (68), an infeed funnel (22) for guiding the rolling door or rolling grille armor (68) into an entry area of the guide rail (12), with the infeed funnel (22) being movable relative to the guide rail (12), and comprising a damping body (34) connected to the infeed funnel (22) which dampens vibrations and shocks of the infeed funnel.

Abstract: A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.
