WOOD-DRILL ADAPTER SYSTEMS
BACKGROUND OF THE INVENTION
The following includes information that may be useful in understanding the
present
invention(s). It is not an admission that any of the information provided
herein is prior art, or
material, to the presently described or claimed inventions, or that any
publication or
document that is specifically or implicitly referenced is prior art.
1. FIELD OF THE INVENTION
The present invention relates generally to the field of coring/drilling and
more specifically
relates to wood-drill adapter systems.
2. DESCRIPTION OF RELATED ART
A core drill is a specific drill-device designed to remove material leaving a
distinct cylinder
shaped hole or void, the operation sometimes referred to as coring and/or
drilling. In some
instances, the vacated material removed may be left in the form of a cylinder.
In other
instances the vacated material may be chipped or scraped out and therefore
destroyed. Core
drills may be used for a wide variety of materials such as concrete, rock,
earth, wood, plastic,
masonry or other materials with mixed results. However, typical core drills
are best suited
and most commonly used for hard materials (rock, masonry, concrete, etc.).
Commonly a core drill may be used for concrete. When coring concrete, the
power source of
the drilling operation generally comes from an electric or pneumatic drill
which is mounted
securely to a frame. The motor assembly is generally affixed to the frame on a
track such
that the operator may manipulate the motor assembly and the attached cutting
head up and
Date Recue/Date Received 2021-09-10
down in a linear fashion. The frame arrangement allows the individual who is
performing the
coring to have a stable base such that the core is smooth and uniform with
parallel and clean
hole (e.g., precise, accurate, smooth, etc.). Having a stable base also
improves safety over
hand-held methods of drilling and coring.
One such limitation with the common core drill setup is that the setup is
limited to concrete,
masonry or other hard surfaces as the core drill itself is not suited for
softer materials such as
wood. Drilling and/or coring of wood typically utilizes a hole saw or self
feeding bit to
remove material such that the hole left is cylindrical in shape. A drill-press
may be employed
to provide in instances where the wood to be drilled is small enough to be
held or carried by
an individual to provide a clean hole, however in instances where the wood is
permanently or
semi-permanently affixed to a structure a drill-press cannot be used. It would
be
advantageous to have the safety and stability of a core drill used for
concrete with the
capability to drill and/or core wooden materials, similar to a drill-press in
a novel form.
Therefore a suitable solution is desired.
Several attempts have been made to solve the above-mentioned problems such as
those found
in U.S. and Foreign Pat. and Pub. Nos. US 3,162,066 to Morey et al.; US
3,464,655 to
Schuman; US 3,977,480 to Hilding; US 6,908,264 to Gundy; US 7,134,815 to
Steer; US
2005/0161263 to Takano et al.; US 2008/0179105 to Duncan; US 2013/0163933 to
Richt et
al.; CN 2,118,157 to Rubach; and WO 201124604 to Stiebitz. This art is
representative of
coring/drilling. However, none of the above inventions and patents, taken
either singly or in
combination, is seen to describe the invention as claimed.
Preferably, a wood-drill adapter system should provide a user with the ability
to use a
concrete coring drill to drill clean, smooth, and precise holes in a wooden
surface and, yet

Date Recue/Date Received 2021-09-10
would operate reliably and be manufactured at a modest expense. Thus, a need
exists for a
reliable wood-drill adapter system to avoid the above-mentioned problems.
