Abstract: An entrance gate and an automatic parking garage having such an entrance gate are provided. The entrance gate includes a stationary ground plate; two trace plates thereabove, movable in the plane in any direction in a gliding manner, each for receiving thereon a front and rear wheel of a car; a stationary top plate above the trace plates, having two opposing cut-out windows, with each trace plate exposed through one window; and two centering plates above the top plate, on outer sides of the cut-out windows. The centering plates connect with and are driven by two drive units to affect synchronous counter-movements. When being driven toward each other, the centering plates touch outer sides of tires of a car resting on the trace plates and move the car toward a centerline of the entrance gate, until the centerline of the car is aligned with the centerline of the entrance gate.

Abstract: The device comprises a measuring track (17) through which an object (1) is driven or moved, a laser (2) having a telecentric lens/Fresnel lens (3) for producing a perpendicular beam curtain (4) extending transversely to the measuring track (17). Furthermore, a camera (6) with an offset to the laser (2) in the longitudinal direction of the measuring track (17) likewise having a telecentric lens/Fresnel lens (7) placed in front. All light points of the laser light line (5) incident on the floor of the measuring track (17) that are reflected undisturbed on the floor of the measuring track (17) are detected at an acute angle from the beam curtain (4) using said camera. Furthermore, means for detecting and recording the speed of the object (1) moved on the measuring track (17) through the beam curtain (4) are provided so that a distance-time diagram can be created.

Abstract: The elevator system for vehicles is intended for a parking garage having a central elevator shaft (13) consisting of two semi-circles. Parking areas (14) are arranged around the elevator shaft at different levels. Each area has a central semi-circle shaped inner edge (16) adjoining the elevator shaft (14). The elevators which can be operated independently of each other, are arranged in the elevator shaft. Each elevator platform (1) is supported on an approximately diametric cross beam (17) extending over the elevator shaft (1). The platform (1) extends there from halfway into the elevator shaft (13). The cross beam (17) is mounted and guided on vertical rails (8, 28) outside of the elevator shaft (13). The carrying cables (6) for the cross beam (17) having the platform (19) and for the counterweight (7) are arranged outside of the central elevator shaft (13), above the top parking deck (9).
