A handrail and crash rail comprises a rigid retainer and a cover of a resilient, impact-resistant plastic mounted on the retainer by means of upper and lower flanges on the cover which engage and are held on corresponding flanges on the retainer. Clearances are left between the impact wall of the cover and the front surfaces of the retainer flanges so that the cover can deflect inwardly toward the retainer upon impact. At least one longitudinally extending, resiliently compressible cushion mounted on the retainer between the retainer flanges engages the impact wall of the cover to control the extent of deflection of the cover upon impact, absorb some of the energy of the impact, and restore the cover to its initial position after impact. Additional cushions can be included. Special internal and external corner assemblies and an end assembly are used with rail sections to form a complete rail system.
In a handrail and crash rail which includes a substantially rigid elongated retainer of uniform cross section along its length and having in cross section a medial portion and upper and lower flanges and a cover of a resilient impact-resistant polymeric material having an impact wall portion and upper and lower flanges joined integrally to the impact wall portion, the respective upper and lower flanges of the retainer and cover being in engagement so that the cover is held on the retainer and the medial portion of retainer and the impact wall portion of the cover being spaced-apart to allow deflection of the cover toward the retainer upon impact, the improvements wherein there is a rib on the retainer located about midway between the retainer flanges, projecting toward the cover from the medial portion of the retainer and imparting longitudinal rigidity thereto, wherein there is at least one longitudinally extending resilient compressible cushion mounted on the rib and engaging the impact wall portion of the cover, and wherein there are clearances between the front surfaces of the retainer flanges and the portions of the cover outwardly therefrom so that the impact wall portion of the cover can deflect toward the retainer throughout its vertical extent upon impact and is restored to its initial position by the cushion.
