Abstract

A device is provided for releasably securing a parked vehicle to an adjacent structure. The device includes a pivotally mounted elongated unit which is movable between a vehicle-interlocking operative mode and a vehicle-release inoperative mode. The elongated unit is mounted on a carriage, which is connected to the structure. The elongated unit is moved from an inoperative mode to an operative mode by hydraulic power means. The hydraulic power means includes a piston-cylinder assembly having the cylinder thereof pivotally connected to the carriage and the exposed end of the piston in operative engagement with the elongated unit whereby movement of the piston in one relative direction effects movement of the elongated unit from the inoperative mode to the operative mode. The power means also includes a manually operable pump means remotely situated relative to the carriage, and an elongated flexible pressure-transmitting means having one end thereof connected to the cylinder and the opposite end connected to the pump means.
