Multi-layer impact resistant bumper

Abstract

An impact resistant bumper device that is elongated along a longitudinal axis and mountable on a mounting member, the device having a cross-section having an open undersurface configuration comprising: a first layer of a first polymer material; a second layer of a second polymer material; a third layer of a third polymer material; wherein the first polymer material has been melted at least once prior to the extrusion cycle, the second polymer material is first melted during the extrusion cycle and the third polymer material is first melted during the extrusion cycle.

What is claimed is: 
     
         1 . An impact resistant bumper device that is elongated along a longitudinal axis and mountable on a mounting member, the device having a cross-section having an open undersurface configuration comprising:
 a first layer of a first polymer material consisting essentially of a recycled mixture of polymer materials;   a second layer of a second polymer material, said second polymer material consisting essentially of virgin polymer material;   wherein the first layer is formed into an inner core body having an outer surface and an open undersurface;   wherein the second layer is formed into a layer bonded to the outer surface of the first layer; and   a third layer of a third polymer material formed into an elongated strip bonded to the undersurface of the first layer , said third polymer material consisting essentially of virgin polymer material.   
     
     
         2 . The impact resistant bumper device of  claim 1  wherein the first and second layers are co-extruded simultaneously through a die and bonded during the extrusion cycle. 
     
     
         3 . The impact resistant bumper device of  claim 1  wherein the first polymer material has a durometer selected to be manually bendable and compressible; and,
 wherein the second polymer material has a durometer greater than the hardness or durometer of the first polymer material. 
 
     
     
         4 . The impact resistant bumper device of  claim 3  wherein the third polymer material has a durometer greater than the durometer of the first polymer material and greater than the durometer of the second polymer material. 
     
     
         5 . The impact resistant bumper device of  claim 1  wherein the first, second and third polymer materials each separately comprise a polyvinyl chloride. 
     
     
         6 . The impact resistant bumper device of  claim 5  wherein the first, second and third polymer materials each separately consist essentially of a polyvinyl chloride. 
     
     
         7 . An impact resistant bumper device that is elongated along a longitudinal axis and mountable on a mounting member, the device having a cross-section having an open undersurface configuration comprising:
 a first layer of a polymeric material consisting essentially of recycled polyvinyl chloride;   a second layer of a polymeric material consisting essentially of virgin polyvinyl chloride;   wherein the first layer is formed into an inner core body having an outer surface and an open undersurface;   wherein the second layer is formed into a layer bonded to the outer surface of the first layer; and   a third layer of a polymeric material consisting essentially of virgin polyvinyl chloride that may be the same as or different from the virgin polyvinyl chloride of the second layer, said third layer formed into an elongated strip bonded to the undersurface of the first layer.   
     
     
         8 . The impact resistant bumper device of  claim 7  wherein the polymeric material of the first layer has a durometer selected to be manually bendable and compressible; and,
 wherein the polymeric material of the second layer has a durometer greater than the durometer of the polymeric material of the first layer. 
 
     
     
         9 . The impact resistant bumper device of  claim 7  wherein the polymeric material of the third layer has a durometer greater than the durometer of the polymeric material of the first layer.
