So What
’
s New?
Bruno Desnoulez and Andre Dejoux of
Neuilly, France patented a tackle reduction
corkscrew back in 1983. The original design
has a pulley system. A handle is attached to
the pulley via a
“
rope
”
which pulls a cork out
when the handle and a series of telescoping tubes are lifted. The mechanical
patent (No. 4,93,733) acknowledges the 1908 German
patent (No. 204,020) by Klostermann and a 1970 French
Patent (No. 1,589,350 by Aimé Ceppe.
In discussing the Klostermann and Ceppe patents,
Bruno and Andre state
“
The embodiment of these
corkscrews is complicated and onerous; moreover, they
generate friction that cause a part of the gain in the
reduction of the removal effort to be lost.
”
In their 1983
patent they cover three different designs including a t-
handle telescoping version and a ring pull version.
On April 10, 1990 Bruno received United States Design
Patent Number D307,102 for a casing design for the
1983 patent. His patent was assigned to Anne-Marie Prevost in Paris. The design
application was filed in 1987 and it was marketed under the names
“
Kariba
”
and
“
Liftboy
”
. The
“
barrels
”
are plastic and were produced in red, white, black and
silver.
