During the manual assembly of any product in a manufacturing environment, the
people who
actually perform the assembly in most cases use either air or electric powered
tools with various
attachments i.e. extensions, sockets or screw driver bits to complete their
work. Over recent years
through Ergonomic research, it has been found that the vibration resulting
from the looseness in the
connections between the tools and these attachments is causing injuries to the
production personnel
who are continually being exposed to this vibration. These injuries are adding
a great deal of cost to
the manufacturing process as a result of employee lost time incidents.
The invention I am seeking to patent is a simple nylon or aluminum collar type
mechanism
that fits snugly over the body of the tool with a fastening mechanism to hold
it in place. The front of
the collar containing a bearing slides over the attached extension and then by
means of a taper thread
lock mechanism is tightened securely to the extension. This mechanism
completely removes the
vibration at the joint between the tool and the extension which results when
the tool is operated.
Injuries will be reduced, tools will last longer and quality will increase.
