fig4 6 the leg guide system of the present invention is shown to comprise a plurality of edge guides 36 positioned along the opposite edges of the rack 24 a plurality of face guides or face guide plates 40 is secured in a transverse relationship to the edge guides 36 extending in a generally parallel relationship to a face 42 of the rack 24 the face guides 40 extend to a distance toward a center of the rack 24 in a typical design there may be two to four face guides 40 although a larger number may be employed depending on the complexity and the load transfer requirements the face guide plates 40 are installed in strategic locations fig4 at the level of lower wear plates along the vertical extension of the guide system each face guide plates 40 is detachably secured to an attachment member 44 by bolts or other similar method in this position an inner surface 46 of each face guide plate 40 contacts a side of the edge guide plate 36 a compressible member 50 is fitted behind each edge guide plate 36 the compressible member 50 is formed from a compressible resilient elastic material capable of withstanding compressive loads acted on the edge guide plate 36 the compressible member 50 allows for changes in stiffness of the edge guide plates 36 to absorb the compressive loads on the edge guides or edge guide plates 36 in conventional systems high compressive loads are.
