Appl. No.:

09/631042

Inventors:

Jonathon R. Saul - Erie MI
David R. Collins - Ida MI
David E. Harnadek - Franklin MI
Duane M. Perpich - Ida MI

Assignee:

The Coleman Company, Inc. - Wichita KS

International Classification:

A47C 430

US Classification:

297 162, 297 42, 297 44, 297 45, 297 52

Abstract:

A folding chair includes collapsible rungs permitting folding in two directions. Stability is further enhanced by the upholstery which further forces the top rung of the chair downward making the chair rigid in the open position. Side rails and back supports slide freely along the chairs rear legs creating a folding mechanism that folds the seat upwards while also pulling the rear leg upwards in the same direction resulting in greater stability without increasing the height of the folded package.

Abstract:

A folding chair includes collapsible rungs in a backrest and seat permitting folding in two directions. Stability is further enhanced by the upholstery which further forces the top rung of the chair downward and the center rung rearward, making the chair rigid in the open position.

Abstract:

A compressor assembly is disclosed. The compressor assembly may have a compressor housing, which may have an inner wall inclined at a first angle relative to a plane disposed generally orthogonal to a rotational axis of the compressor assembly. The compressor assembly may also have a compressor impeller disposed within the compressor housing. Further, the compressor assembly may have a bearing housing attached to the compressor housing. The bearing housing may have a body portion and a web that may extend outward from the body portion to a web end. The web may be inclined at a second angle relative to the plane. The compressor assembly may have a diffuser ring disposed between the inner wall and the web. The compressor assembly may also have a spring disposed between the web and the diffuser ring. The spring may be configured to apply a generally axial load on the diffuser ring.
