Filed:

Jan 12, 2001

Appl. No.:

09/759943

Inventors:

William S. Chamberlain - Rochester MI
David Otto - Lake Orion MI

Assignee:

JS Chamberlain Assoc. - Troy MI

International Classification:

B23K 26073

US Classification:

21912183, 21912173, 21912169

Abstract:

A method and apparatus for finishing a surface of a vehicle part. A laser surface finishing means includes a finishing laser and at least one surface topography sensor. A first sensor scans each footprint of the surface and measures the footprint height. Each footprint height is compared to a reference height for that footprint area. If the footprint height is above the reference height, the laser generates a beam to either remove or cause reflow of a predetermined amount of material from the high points. These steps are repeated in a predetermined scanning pattern until each footprint height is not above the reference height for that footprint. In one aspect, a second sensor scans each footprint of the surface after the laser operates or not, and the height measured by the second sensor is used to determine if the steps need to be repeated.

Assignee:

JS Chamberlain Associates, Inc. - Troy MI

International Classification:

B60J 504

US Classification:

2961465, 2961467, 296 391

Abstract:

A door protector module includes a unitarily constructed inner belt weatherstrip, a shield and a lower door seal which are attachable as a one piece assembly to a vehicle door inner trim panel or the inner door panel. The inner belt weatherstrip, the shield and the lower door shield are formed with complimentary adjoining shapes for affixing the inner belt weatherstrip, the shield and the lower door shield into a unitary structure by snaps, fasteners, adhesive, etc.

Appl. No.:

11/105694

Inventors:

Kenneth H. Ward - Pearson MI, US
David J. Otto - Lake Orion MI, US

Assignee:

Nicholas Plastics Incorporated - Allendale MI

International Classification:

B60J 5/00

US Classification:

2961467, 296 108

Abstract:

A vehicle trim panel is secured to a vehicle structural panel by providing a vehicle trim fastener having spaced arms which embrace and overlie the legs on a mount which is seated over the edge of a vehicle structural panel. The embracing arms and corresponding legs prevent lateral shifting of the trim panel relative to the structural panel.

Appl. No.:

10/948906

Inventors:

David Otto - Lake Orion MI, US

Assignee:

JS Chamberlain & Associates, Inc. - Troy MI

International Classification:

E04C 2/00

US Classification:

052232000

Abstract:

A baffle apparatus mountable in a hollow structural member includes first and second sealed containers, each containing a separate reactive component. The first and second containers are formed of complementary melting point materials so as to melt and allow the reactive components to mix and react when the thermal energy is applied to the structural member. The reactive components form an expanded volume foam mass substantially filling, sealing, and/or reinforcing the cross section of the structural member.

Appl. No.:

12/992297

Inventors:

David J. Otto - Lake Orion MI, US
Clayton Raybourn - South Lyon MI, US
Mark Jurcak - Harrison Township MI, US

International Classification:

B32B 38/04

US Classification:

156261, 156391

Abstract:

A tool and method applies a cover to an item receiving face. A base plate has an item receiving surface. A moveable lower plate has a die bore corresponding to the cover receiving surface of the item and a receiving surface for a laminate cover material having an adhesive layer and a decorative base layer. An upper plate includes a channel corresponding with the lower plate die and a punch secured within the upper plate channel and slideably engageable within the die. The punch has a centrally located bore and cutting edge. A compressible member disposed within the punch bore has a curvolinear free end. The upper plate is displaced towards the lower plate in a closed state to slidingly engage the punch within the die and the punch cutting edge punches out the cover while the compressible member presses the cut cover onto the item receiving face.

SIKA Corporation - Southfield MI

International Classification:

B32B 500

US Classification:

428 98

Abstract:

An expandable baffle apparatus for sealing a cavity of an automobile or the like includes a piece of heat expandable sealing material that is formed in a shape corresponding to the shape of the cross section of the cavity to be sealed. A support element supports the piece of sealing material at the predetermined cross section while the apparatus is subjected to an elevated activation temperature at which the sealing material expands to seal the cavity at the cross section. The support element is formed of a material having a melting point higher than the activation temperature, and includes an open lattice formed of a shape corresponding to the shape of the cross section of the cavity. The sealing material is supported on the lattice so that when the sealing material is activated, the material expands radially to fill the cross section of the cavity and longitudinally through the lattice.
