ABSTRACT:
A device is provided for releasably securing a parked vehicle to an adjacent structure. The device is provided with a first member hingedly mounted for movement between an operative mode and an inoperative mode. When the first member is in an operative mode the distal end thereof will releasably engage a portion of the parked vehicle and retain same in a desired position relative to the adjacent structure. When the first member is in an inoperative mode, it assumes a vehicle-release position. The first member is provided with means for moving same from the inoperative mode to the operative mode. A further means is provided for automatically locking the first member in an operative mode. The further means includes a means for effecting controlled unlocking of the first member whereby the latter will automatically return to its inoperative mode. The first member and associated means are mounted so as to move as a unit in a substantially vertical direction to compensate for dimensional variations occurring in the various vehicles parked next to the adjacent structure.
