ABSTRACT:
A pallet rack lock for use in a pallet rack system releasably locking one end of a shelf beam to an upright column is the subject matter of this invention. The column has a plurality of vertically spaced locking apertures. The rack lock includes a rock lock plate fixed to the shelf beam and positioned substantially parallel to the upright column. A load bearing stud is fixed to the lock plate. The stud is positioned in a lower portion of a locking aperture. A resilient carrier has one end fixed to the locking plate and the opposed end being free. A lock stud is mounted on the resilient carrier for movement therewith. The lock stud is positioned in an upper portion of a locking aperture to prevent upward movement of the load bearing stud. A dog limits the movement of the resilient carrier away from the lock plate. The lock stud may be selectively moved out of its locking aperture by bending a portion of the resilient carrier. The dog limits bending of the resilient carrier to prevent permanent deformation of the carrier.
