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. |
