Low Profile Wheel Chocking System and Chock Construction

摘要

A wheel chock is constructed from metallic material has an elongate primary body construction. The primary body construction has a Π-shaped transverse cross-section formed by an upper C-shaped channel construction and a lower planar basal construction. The basal construction has U-shape that extends orthogonally relative to the C-shape of the channel construction. The Π-shaped transverse cross-section bears and distributes stress imposed on the primary body construction. The C-shaped channel construction preferably includes a series of apertures for reducing weight and controlling elastic response of the primary body construction. Among these apertures are edge-based apertures, arm-based stress relief slots, and aligned apertures having sequentially decreasing diameters.

1: A low-profile wheel chocking system for chocking and restraining a wheel upon a support surface adjacent a rail mounted to the support surface, the wheel chocking system comprising:
a pair of low-profile chock assemblies, each chock assembly comprising a primary body construction and fastening means, each primary body construction having a primary length extending in a first dimension, the fastening means being located inwardly of a first end of each primary body construction, each primary body construction comprising a Π-shaped transverse cross-section extending in a second and a third dimension, the Π-shaped transverse cross-sections each comprising opposed I-beam sections integrally interconnected at an upper span portion, the Π-shaped transverse cross-sections for bearing and distributing stress imposed on each primary body construction, the fastening means for fastening each chock assembly to the rail such that the chock assemblies are parallel to one another and orthogonal to the rail in chock adjacency to the wheel, the wheel being radially orthogonal to each chock assembly.
