Multi-layer impact resistant bumper

An impact absorbing and resistant bumper readily attachable to and detachable from a base, the impact absorbing and resistant bumper comprising:

• an elongated body having a longitudinal axis and being resistant to impact, the elongated body comprising:
• a first body layer comprised of a first polymeric material having a first selected degree of hardness;
• a second layer of a second polymeric material having a second degree of hardness greater than the degree of hardness of the first polymeric material;
• wherein the first body layer and the second layer are extruded or molded simultaneously and adhered to each other along the elongated axis of the strip, the elongated body having a body configuration taken along a section transverse or radial to the longitudinal axis that forms an enclosure having a curved outer surface and an open undersurface accessible for reversibly attaching to a base;
• the first body layer having a configuration taken along a section transverse or radial to the longitudinal axis that has a transverse center, a stable transverse width when the elongated body is in a relaxed state and includes an enclosed center aperture embedded within the first body layer and a pair of open recesses embedded within the first body layer that are disposed laterally adjacent the center aperture, the aperture and recesses extending longitudinally along the longitudinal axis of the elongated body;
• the center aperture having a configuration that is generally T-shaped having a widened head portion that is curved along a top end of the center aperture and a leg portion that extends distally from the head portion toward the distal undersurface, the lateral recesses being disposed within the first body layer on opposite lateral sides of the center aperture;
• the second layer being disposed on a distal undersurface of the first body layer and formed into a configuration that mates with a complementary groove formed in the base such that the elongated body is reversibly attachable to and detachable from the base.

An impact absorbing and resistant bumper for mounting on a base structure, the bumper comprising:

• an elongated body having a longitudinal axis and being resistant to impact, the elongated body comprising:
• a first body layer comprised of a first polymeric material having a first selected degree of hardness;
• a second layer of a second polymeric material having a second degree of hardness that is greater than the first degree of hardness of the first material;
• wherein the first body layer and the second layer are extruded or molded simultaneously and adhered to each other to extend along the elongated axis of the body, the elongated body having a body configuration taken along a section transverse or radial to the longitudinal axis that forms an enclosure having a continuous curved outer or upper surface and an open undersurface accessible for reversibly attaching to a base;
• the first body layer having a configuration taken along a section transverse or radial to the longitudinal axis that is formed and selected to enable the elongated body to be deformed or bent along a selected length along its longitudinal axis into a bent portion having a bend radius of curvature of up to as little as about 2.5 inches at a bend angle of about ninety degrees wherein the bent portion can remain attached to the base at the bend angle of about ninety degrees with the bend radius of up to as little as about 2.5 inches;
• the second layer being disposed on a distal undersurface of the first body layer and formed into a configuration that is readily attachable to and detachable from a complementary receiving groove formed in the base.

An impact absorbing and resistant bumper for mounting on a base, the impact absorbing and resistant bumper comprising:

• an elongated body having a selected radial or transverse width in a relaxed state, the elongated body having a longitudinal axis and being resistant to impact, the elongated body comprising:
• a first body layer comprised of a first polyvinyl chloride polymeric material having a first selected degree of hardness, the first body layer comprising at least about 80% by weight of the elongated body and containing 3% or more of a plasticizer material;
• a second layer of a second polyvinyl chloride polymeric material having a second degree of hardness greater than the first degree of hardness and containing less than about 0.3% of a plasticizer material;
• a third layer of a third polyvinyl chloride polymeric material having a third degree of hardness greater than the first degree of hardness and containing 3% or more of a plasticizer material;
• wherein the first body layer, the second layer, and the third layer are extruded or molded simultaneously and adhered to each other along the elongated axis of the strip, the elongated body having a body configuration taken along a section transverse or radial to the longitudinal axis that forms an enclosure having a curved outer surface and open undersurface accessible for reversibly attaching to the base;
• the first body layer being extruded or molded to have a configuration taken along a section transverse or radial to the longitudinal axis enclosing a center aperture, the first body layer comprising a pair of lateral recesses extending along the longitudinal axis of the elongated body, wherein the center aperture is generally T-shaped having a widened head portion that is curved along a top end of the center aperture and a leg portion that extends distally from the head portion toward the distal undersurface, the lateral recesses being disposed within the first body layer on opposite lateral sides of the center aperture;
• the second layer being disposed on a distal undersurface of the first body layer and formed into a configuration that is readily attachable to and detachable from a complementary groove formed in the base;
• the third layer being extruded onto and forming the curved outer surface of the elongated body;
• the first polyvinyl chloride polymeric material being melted at least once prior being extruded into the elongated body;
• the third polyvinyl chloride polymeric material not being melted prior to being extruded into the elongated body.
