Appl. No.:

29/153135

Inventors:

Charles Mehrmann - Lynnwood WA
Brian Vehige - Seattle WA

Assignee:

Wham-O, Inc. - Emeryville CA

International Classification:

1214

US Classification:

D12 11

US Patent:

Filed:

Sep 17, 2004

Appl. No.:

10/943457

Inventors:

Charles Mehrmann - Lynnwood WA, US

Assignee:

Wham-O, Inc. - Emeryville CA

International Classification:

B62B 3/06

US Classification:

280 18, 280 211, 280 2816

Abstract:

The invention features a soft foam sled board for use by a sitting or kneeling rider to slide over a snow or ice covered surface. The sled is prepared from a shaped polyethylene foam core, and at least the bottom surface of the core is covered by a slick, polyethylene film/polyethylene foam sheet laminate which provides little frictional resistance between the sled board and sliding surface, and provides an impervious outer surface to the board so as to resist puncture and water infiltrate. The sled board has one or more rails, ribs, or fins embedded below the body weight of the rider so as to either protrude from, or jut into, the board. The fins enhance the ability of the sled board to travel down the hill in a straight, forward direction.

International Classification:

A63C005/03

US Classification:

280/014210, 280/018000

Abstract:

The invention features a sliding device, such as a sledboard, having upwardly turned ends at each end of the board, so as to be ridden with either end of the device facing in the leading direction, i.e., when used on a downward slope, in the downhill direction. The sliding device has both an upturned leading end and an upturned trailing end. The sliding device is thereby able to spin around and is able to ride in both directions, enabling a rider or riders to ride backwards or forwards. These upturned or “flipped-up” ends also confer the advantage of preventing one end of the sled from acting as a brake by digging into the snow and stopping the sled. This allows the sled to travel down the hill no matter which end is facing down the hill.

Appl. No.:

Inventors:

Charles Mehrmann - Woodinville WA, US

International Classification:

B62B009/04

US Classification:

280018000

Abstract:

A lightweight toboggan capable of being used by small children and adults that includes a runner surface made of sufficiently durable material for repeated use and an upper foam shell for greater comfort and injury protection. The toboggan is also designed for greater tracking and steering. The above objects are met by using a toboggan that includes a lower runner shell made of hard plastic, such as ABS or high density polyethylene that includes two curved side cuts formed on the opposite sidewalls and an optional V-shaped center tunnel. The two side cuts are located in parallel to the direction of travel on the edge of the riding surface so that they do not engage the snow or ice surface when the toboggan is flat and ridden in a straight line. When the rider leans and lifts one side of the toboggan, the opposite side cut is rotated downward to engage the snow or ice causing the toboggan to turn. The perimeter edges of the lower runner shell and the upper foam shell are coupled together to create an aesthetically pleasing seam that resists delamination. The upper foam shell substantially reduces the toboggan's weight, serves to protect and hide the channels and arcs, and provides greater comfort and edge protection with impacts.

Assignee:

Earth & Ocean Sports, Inc. - Redmond WA

International Classification:

A63B 3108

US Classification:

441 64

Abstract:

A swim fin having a foot section with a foot cavity, a soft rubber foot pocket, and a blade section composed of blended cured layers of rubber sheet materials of selected durometer hardness. The swim fin is prepared by placing layers of sheet materials of different durometer hardness about a foot last and compression and heat molding the layers to form a molded, multiple layered, integral swim fin of selected durometer hardness.
