Douglas Michael Johnson - Dorr MI, US
Clarke Kenton Crump - Byron Center MI, US
International Classification:
A47B 95/02
US Classification:
16422
Abstract:
The objective of the invention is to solve problems relating to: mounting handles quickly and easily; material requirements and finishes; difficult shapes and sizes; cost; assembly and removal; replacement options not current available to the consumer; marketability; package and shipping. How it solves these problems: mounts with or without fasteners; all plastics and steel material design options; compliments difficult shapes because of plastic molding options; cost is less because material content is less and manufacturing is a standard process; assembles easy and is removable to the consumer or manufacturer, offering ability to replace for damage and/or consumer preference; marketability is driven by these benefits; package and shipping is improved based upon assembly by consumer options.

Method For Making Threaded Tube

US Patent:
8356396, Jan 22, 2013
Filed:
Sep 3, 2009
Appl. No.:
12/553323
Inventors:
Douglas M. Johnson - Dorr MI, US
Assignee:
Middleville Tool & Die Company - Middleville MI
International Classification:
B21D 39/03, B23P 11/00
US Classification:
292811, 292813, 269 55, 470 57, 7240501
Abstract:
The invention includes a method, and a component made according to the method having at least one thread pattern formed thereon from a stamping method. The invention includes a tubular member comprising a body having a wall formed from a wrapped sheet of stock to define an interior wall and an exterior wall, a seam in the wall defining a first and second end of the wrapped sheet of stock, and a thread pattern stamped on the exterior wall. The method comprises the steps of forming a blank from sheet of stock having a first surface. A thread pattern is formed onto the first surface while in a substantially sheet-like form. A bending operation then forms the sheet stock into a tubular member such that the thread pattern, located on the tube's external surface, is substantially aligned about its circumference.
