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.

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 having a first hardness or durometer;   a second layer of a second polymer material having a second hardness or durometer;   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;   a third layer of a third polymer material formed into an elongated strip bonded to the undersurface of the first layer;   wherein the first polymer material has been melted at least once prior to the extrusion cycle,   wherein the second polymer material is first melted during the extrusion cycle; and,   wherein the third polymer material is first melted during the extrusion cycle.   
     
     
         2 . The elongated strip of  claim 1  wherein the first and second layers are co-extruded simultaneously through a die and bonded during the extrusion cycle. 
     
     
         3 . The elongated strip of  claim 1  wherein the first polymer material has a hardness or durometer selected to be manually bendable and compressible; and, wherein the second polymer material has a hardness or durometer greater than the hardness or durometer of the first polymer material. 
     
     
         4 . The elongated strip of  claim 3  wherein the third polymer material has a hardness or durometer greater than the hardness or durometer of the first polymer material.
