Dual durometer rub rail

Claim 2

An extruded rub rail member defining an axis of extrusion and being adapted for secure attachment to a well-mounted attachment means, the rub rail member comprising: a first portion having a predetermined width and a length extending in the direction of said axis of extrusion, said first portion including engaging means, carried by one surface, for engaging the wall-mounted attachment means; a second portion having a predetermined width and a length extending in the direction of said axis of extrusion, said second portion overlying and engaging the surface of said first portion disposed opposite to said one surface and being integral therewith; said first and second portions being disposed in contiguous engagement throughout their entire widths and lengths, said first portion consisting of a rigid plastic material, and said second portion consisting of a flexible plastic material, said rub rail member being sufficiently thin so as to be bendable in its widthwise direction to form an arcuate configuration and coilable in its lengthwise direction.

Claim 3

The extruded rub rail member of claim 1, wherein said plastic material of said second member includes a coloring material uniformly dispersed throughout.

Claim 4

The extruded rub rail member of claim 1, wherein said engaging means of said first member comprises a pair of arms spaced from one another and configured for engagement with the wall-mounted attachment means.

Claim 5

A rub rail member in accordance with claim 1, in longitudinally coiled form.

Claim 6

A rub rail member in accordance with claim 1, secured to the attachment means, and having an arcuate cross-sectional configuration.

Claim 7

A rub rail member having an elongated form and comprising: a thin upper layer of flexible plastic or elastomeric material having a durometer value of 65-95 Shore A and a thickness sufficiently small as to permit co-extrusion thereof in a consistent uniform fashion, said upper layer being regular and uniform without surface defects; and a thin lower layer of stiff plastic material having a durometer value greater than that of said flexible plastic and a thickness sufficiently small so that said rub rail member can be coiled longitudinally and flexed laterally; said upper layer and said lower layer being adjacent and overlying contiguous layers integral along coextruded faces thereof and having a combined thickness of no greater than about 80 mils.

Claim 8

A rub rail member having an elongated form and comprising: a thin upper layer of flexible plastic or elastomeric material having a durometer value of 65-95 Shore A and a thickness sufficiently small as to permit co-extrusion thereof in a consistent uniform fashion, said upper layer being regular and uniform without surface defects; and a thin lower layer of stiff plastic material having a durometer value greater than that of said flexible plastic and a thickness sufficiently small so that said rub rail member can be coiled longitudinally and flexed laterally; said upper layer and said lower layer being adjacent and overlying contiguous layers integral along coextruded faces thereof and having a combined thickness of no greater than about 80 mils.

Claim 9

A rub rail member according to claim 6 wherein said upper layer is formed of soft PVC and said lower layer is formed of hard PVC.

Claim 10

A rub rail member according to claim 6 wherein said upper layer has a thickness on the order of about 20-50 mils, and said lower layer has a thickness on the order of about 20-60 mils.

Claim 11

A rub rail assembly, comprising: a first extruded rub rail support member having an axis of extrusion and means extending normal to said axis of extrusion for attaching said first support member to a surface to be protected; a second extruded rub rail member engaged with said first extruded rub rail support member, said second rub rail member having an axis of extrusion disposed parallel to said axis of extrusion of said first rub rail member, said second rub rail member including two thin adjacent and overlying contiguous layers of plastic material having a combined thickness of no greater than about 80 mils, a first of said thin layers disposed closest to said first rub rail support member being secured to said first rub rail support member and consisting of a substantially rigid plastic material, a second of said thin layers disposed away from said first rub rail support member consisting of a substantially flexible plastic or elastomer material, the width of said second rub rail member being substantially more than the width of said first rub rail support member, such that when said first layer of said second rub rail member is secured to said first rub rail support member, said first and second layers of said second rub rail member are deformed arcuately about said axis of extrusion, and said second rub rail member delimits a cylindrical segment.

Claim 12

A rub rail assembly, comprising: a first extruded rub rail support member having an axis of extrusion and means extending normal to said axis of extrusion for attaching said first support member to a surface to be protected; a second extruded rub rail member engaged with said first extruded rub rail support member, said second rub rail member having an axis of extrusion disposed parallel to said axis of extrusion of said first rub rail member, said second rub rail member including two thin adjacent and overlying contiguous layers of plastic material having a combined thickness of no greater than about 80 mils, a first of said thin layers disposed closest to said first rub rail support member being secured to said first rub rail support member and consisting of a substantially rigid plastic material, a second of said thin layers disposed away from said first rub rail support member consisting of a substantially flexible plastic or elastomer material, the width of said second rub rail member being substantially more than the width of said first rub rail support member, such that when said first layer of said second rub rail member is secured to said first rub rail support member, said first and second layers of said second rub rail member are deformed arcuately about said axis of extrusion, and said second rub rail member delimits a cylindrical segment.

Claim 13

A rub rail assembly according to claim 9 wherein the first of said layers is formed of hard PVC and the second of said layers is formed of soft PVC.

Claim 14

A rub rail assembly according to claim 9 wherein said first of said layers has a thickness on the order of about 20-60 mils, and the second of said layers has a thickness on the order of about 20-50 mils.

Claim 15

An extruded rub rail member according to claim 1 wherein said first and second portions have a combined thickness of about 40-60 mils.

Claim 16

A rub rail member according to claim 6 wherein said upper layer and said lower layer have a combined thickness of about 40-60 mils.

Claim 17

A rub rail assembly according to claim 9 wherein said two thin adjacent and overlying contiguous layers have a combined thickness of about 40-60 mils.
