BACKGROUND OF THE INVENTION
Referring to Figures 1 and 2, a conventional wooden
newel post 1 is shown to have a height and width, and
is formed by interconnecting three wooden boards 101
side-by-side along the width of the wooden newel post


CA 02442196 2003-09-23

1 to form a rectangular raw post body. Each of the wooden
boards 101 is made of higher quality wood, such as oak
or maple, and extends the full height of the wooden newel
post 1 . The post body is lathed so as to form a contoured
upper post section 2, and a lower post section 3 having
a rectangular cross-section. The standard
specification of the wooden newel post 1 is 43 to 72
inches in height . Higher quality wood materials having
no scars, no mineral lines, and having sufficient length
are selected to produce the conventional wooden newel
post 1.
SUMMARY OF THE INVENTION
The main obj ect of the present invention is to provide
a wooden newel post that is made from a combination of
higher and lower quality wood materials so as to help
reduce consumption of higher quality wood.
According to this invention, a wooden newel post
having a height and width comprises an upper newel post
section, a lower newel post section, and a decorative
lamella layer. The upper newel post section is made of
higher quality wood, and has a lower post connecting
end. The higher quality wood is selected from the group
consisting of oak wood and maple wood. The lower newel
post section is made of lower quality wood, and has an
upper post connecting end connected to the lower post
connecting end of the upper newel post section, and an
outer newel post surface. The lower quality wood is


CA 02442196 2003-09-23
selected from the group consisting of rubber wood and
pine wood from plantation forests, defective higher
quality wood, and high density fiber material. The
decorative lamella layer is made of higher quality wood,
and is secured to the outer newel post surface of the
lower newel post section.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figures 3 to 6, the preferred embodiment
of a wooden newel post 100 according to the present
invention is shown to have a height and width, and
comprises an upper newel post section 10, a lower newel
post section 20 connected to the upper newel post section
10, and a decorative lamella layer 30 adhered to an outer
newel post surface of the lower newel post section 20.
The upper newel post section 10 is made of hard higher
quality wood, such as oak wood and maple wood, and extends
at least one-half of the full height of the wooden newel
post 100. In this embodiment, the upper newel post
section 10 extends to approximately two-thirds of the
full height of the wooden newel post 100, and has a top
end portion 11, a lower post connecting end 12 opposite
to the top end portion 11, and a contoured outer newel
post surface 13 that extends along the full height of
the upper newel post section 10. The upper newel post
section 10 includes three wooden boards 14 that are
interconnected side-by-side along the width of the
wooden newel post 100, such as by gluing, and that extend


CA 02442196 2003-09-23
along the full height of the upper newel post section
10. Lower ends 141 of the wooden boards 14 correspond
to the lower post connecting end 12 of the upper newel
post section 10.
The lower newel post section 20 is made of lower
quality wood, such as rubber wood and pine wood from
plantationforests, defective higher quality wood, and
high density f fiber material . The lower newel post section
20 has a rectangular cross-section, an upper post
connecting end 21, a bottom end portion 22 opposite to
the upper post connecting end 21, and an outer newel
post surface 23 that extends along the full height of
the lower newel post section 20. The lower newel post
section 20 includes three wooden boards 24 that are
interconnected side-by-side along the width of the
wooden newel post 100, such as by gluing, and that extend
along the full height of the lower newel post section
20. Upper ends 241 of the wooden boards 24 correspond
to the upper post connecting end 21. Each wooden board
24 includes two board sections 24' that are
interconnected to each other along the full height of
the lower newel post sect ion 20 by means of f finger j oints .
The upper ends 241 of the wooden boards 24 of the lower
newel post section 20 and the lower ends 141 of the wooden
boards 14 of the upper newel post section 10 are
interconnected by means of finger joints, such that the
lower newel post section 20 extends continuously from


CA 02442196 2003-09-23
the upper newel post section 10 along the full height
of the wooden newel post 100.
The decorative lamella layer 30 includes 2-8mm
lamella pieces of the same hard higher quality wood used
5 in the upper newel post section 10, and is adhered
securely to the outer newel post surface 23 on four sides
of the lower newel post section 20.
Referring to Figure 6, the wooden newel post 100 of
this invention is manufactured according to a process
that is substantially similar to the conventional one.
Three wooden boards 210 made of higher quality wood are
interconnected respectively with three wooden boards
220 made of lower quality wood so as to form a rectangular
raw post body 200. The post body 200 is lathed so as
to form the contoured outer newel post surface 13 of
the upper newel post section 10.
Although the wooden newel post 100 of the present
invention conveys a continuous higher quality wood
appearance in view of the upper newel post section 10
and the decorative lamella layer 30, as best illustrated
in Figures 3 and 5, the lower newel post section 20 covered
by the decorative lamella layer 30 can be made of lower
quality wood or defective higher quality wood, thereby
reducing consumption of higher quality wood material
to a minimum.
V,Ihile the present invention has been described in
connection with what is considered the most practical


CA 02442196 2003-09-23

and preferred embodiment, it is understood that this
invention is not limited to the disclosed embodiment
but is intended to cover various arrangements included
within the spirit and scope of the broadest
interpretation so as to encompass all such modifications
and equivalent arrangements.
