US Patent:

6848733, Feb 1, 2005
Filed:

Nov 8, 2002
Appl. No.:

10/290676
Inventors:

John C. Montagna - Metamora MI, US
Gary J. Nehring - Linden MI, US
Donald J. LaBelle - Macomb Township MI, US
Assignee:

Durakon Industries, Inc. - Lapeer MI
International Classification:

B60R 1301
B62D 3302
US Classification:

296 392, 296 391
Abstract:

A motor vehicle bed or bed liner is vacuum formed from a panel of co-formed layers of thermoplastic material having a roughened surface. The panel is co-formed of two layers of material having distinct compositions and characteristics. The upper surface of the co-formed composite is then roughened or textured by a brush which contacts one surface. The co-formed and roughened composite panel is then vacuum formed into, for example, a truck bed or bed or cargo compartment liner.

US Patent:

7086680, Aug 8, 2006
Filed:

Feb 6, 2004
Appl. No.:

10/773711
Inventors:

John C. Montagna - Metamora MI, US
Gary J. Nehring - Linden MI, US
Donald J. LaBelle - Macomb Township MI, US
Assignee:

Durakon Industries, Inc. - Lapeer MI
International Classification:

B60R 13/01
US Classification:

296 392
Abstract:

A motor vehicle bed or bed liner is vacuum formed from a single layer or two layer panel of thermoplastic material having a scuffed or roughened surface. The single layer panel is typically extruded and is homogeneous, being either a single material such as HDPE or a uniform mixture of materials. The two layer panel is co-formed of two layers of material which will typically be distinct compositions and characteristics. The upper surface of the panel is scuffed or roughened by a brush which contacts the surface. A bank of individually adjustable rollers supports the panel during the roughening operation and facilitates adjustment of the extent of contact or impingement of the brush on the surface of the panel at a plurality of transverse locations across the panel. The roughened panel is then vacuum formed into, for example, a truck bed or bed or cargo compartment liner.

US Patent:

20040000746, Jan 1, 2004
Filed:

Jun 28, 2002
Appl. No.:

10/186142
Inventors:

John Montagna - Metamora MI, US
Gary Nehring - Linden MI, US
Donald LaBelle - Macomb Township MI, US
International Classification:

B29C051/10
US Classification:

264/544000, 264/104000, 264/173160, 264/148000
Abstract:

A method of manufacturing a laminated pickup truck bed and bed liner includes the steps of forming by extrusion or another process a substrate layer of a desired thickness and strength of a thermoplastic material such as high-density polyethylene (HDPE) which may include fibers or a fibrous mat which improves its strength and ruggedness. Also formed by extrusion or another process is an upper layer having specific characteristics such as electrical charge dissipation or improved skid or slip resistance. The upper layer may be fabricated of a thermoplastic material such as HDPE and includes dispersed conductive material such as carbon particles, carbon, fibers or conductive polymers which dissipate or carry static electrical charges to a vehicle ground. Skid or slip resistance may be achieved by controlling the upper layer surface texture or the use of various materials and mixtures. The two layers are laminated together either with or without the use of an adhesive and then formed into a bed or bed liner by a thermoforming process. Independent manufacture of the extruded layers, the cast film and the blown film provides greatly improved control of the thickness of the individual layers and therefore achieves more predictable product characteristics such as strength and electrical conductivity.

Filed:

Mar 28, 2003
Appl. No.:

10/401423
Inventors:

John Montagna - Metamora MI, US
Donald J. LaBelle - Macomb Township MI, US
Gary J. Nehring - Linden MI, US
International Classification:

B29C047/06
B32B031/30
US Classification:

156/244160, 264/510000, 264/544000, 264/148000, 264/104000, 264/132000, 264/564000, 264/216000, 264/171100
Abstract:

A method of manufacturing a printed, laminated pickup truck bed and bed liner includes the steps of forming by extrusion or another process a single or double layer substrate of a desired thickness and strength. If a single layer, it will preferably be formed of a thermoplastic material such as high density polyethylene (HDPE). If a double layer, the lower layer may be HDPE or HDPE reinforced with random fibers or a fibrous material to improve its strength and ruggedness. Additionally, a cast or blow film upon which may be printed a desired pattern such as, for example, camouflage or indicia, is utilized as the top layer of the material. The two or three layers are laminated together either with or without the use of an adhesive and then formed into a bed or bed liner by a thermoforming process.
