Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to wooden doors used in
buildings, more particularly to a kind of veneered wooden doors and
a method for veneering their sticking profile.
BACKGROUND OF THE INVENTION
[0002] Wooden doors in current use are generally composed of stiles
and rails and core panels. The timber of the door's outer part
determines the name of the door, for example, black walnut doors,
beech doors, maple doors. The more famed and precious the wood, the
higher grade the wooden door will be. To save high quality timber
(like red oak, cherry, maple, beech, black walnut, etc.), and
reduce the manufacturing cost, at present high-grade wooden doors
only use high quality timber for edge bands of the stiles and
rails, stickings of the stiles and rails, as well as veneers, the
main portions of the stiles and rails and the core panels use
ordinary wood materials (soft miscellaneous or inferior materials
such as fir, deal or poplar) or artificial boards (such as density
board, flakeboard or fiberboard, etc.). However, the amount of wood
used in the stickings takes about 30%-50% of all high quality
timber used in the entire door; therefore, if this amount can be
reduced and the wood can be partly replaced with ordinary timber or
artificial board, a considerable amount of high quality timber
resources can be saved, with the manufacturing cost of wooden doors
greatly reduced.
[0003] Once the high quality wood of the stickings are replaced
with ordinary wood or artificial boards, their outer parts shall be
veneered with high quality wood veneers in the same way the stile
and rail cores are veneered, so as to achieve an artistic unity in
appearance. However, the stickings are usually of irregular shapes
(especially those with edges or corners), ordinary veneering
methods can hardly help to create an ideal result of artistic
unity. Thus it is desired to find a way to veneer the wooden doors'
sticking profile, so as to make veneered wooden doors both pleasing
in appearance and practical in use.
SUMMARY OF THE INVENTION
[0004] The purpose of the present invention is to provide a
veneered wooden door, whose stickings of the stiles and rails are
ordinary wood material instead of high quality timber, so as to
greatly lower the production cost of wooden doors.
[0005] The other purpose of the present invention is to provide a
method for veneering the sticking profile of the wooden doors, so
as to seamlessly integrate the surface of the stickings made of
ordinary wood material with that of the stile rail cores, achieving
a uniformed beautiful appearance.
[0006] To achieve the above purposes, the wooden door of the
present invention mainly comprises stiles and rails and core
panels, among which the stiles and rails comprises stile rail
cores, edge bands and stickings. The wooden door of the present
invention is characterized that the high quality timber of the
stickings are replaced with ordinary timber or artificial boards,
with their surface veneered with wood veneers containing high
quality grains.
[0007] The stickings and the stile rail cores can be made of same
wood of ordinary trees or artificial boards in accordance with the
present of the invention, and integrated into a whole, with their
surface veneered with wood veneers containing high quality
grains.
[0008] The method for veneering the sticking profile of the
veneered wooden door in accordance with the present invention
comprises the following steps: applying resin glue on the backside
of the high-grade wood veneers; pasting it on the surface of the
stickings of the wooden door which is previously applied with resin
glue; then putting the wooden door into a tamping machine having
the same shape as the sticking profile, with the temperature at
60.about.120.degree. C., and the pressure at 5.about.15 kg/cm,
applying pressure for 2.about.3 minutes.
[0009] Because the high quality wood of the stickings of the
veneered wooden door in accordance with the present invention is
replaced with wood of ordinary trees or artificial boards, about
30%-50% of the high quality wood is saved, thus greatly lowers the
manufacturing costs of the veneered wooden doors, as well as the
valuable wood resources. On the other hand, the effect brought
about by the replacement of the wood of the stickings upon the
quality of the wooden door is almost negligible, which makes the
present invention deserving to be spread and applied. In addition,
The method for veneering the sticking profile (especially those
with edges and corners) of the stickings of the wooden door in
accordance with the present invention gives the wooden door of the
present invention a perfect appearance, without any impact on the
door's pleasing appearance, stability and durability.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is a front view of the veneered wooden door in
accordance with the present invention.
[0011] FIG. 2 is a section view along I-I of FIG. 1.
[0012] FIG. 3 is a section view along I-I of FIG. 2.
DETAILED DESCRIPTION OF THE INVENTION
[0013] Through the following embodiments of the invention, further
illustrations of the invention regarding the veneered wooden door
and the method for veneering its sticking profile. However, the
embodiments given shall not be deemed as limitations for
restricting the range of application of the present invention.
EXAMPLE 1
[0014] As shown in FIG. 1, a veneered wooden door in accordance
with the present invention mainly comprises stiles and rails 1 and
core panels 2. Also as shown in FIG. 2, the main body 6 of the
stiles and rails 1 are made of wood of ordinary trees, such as fir;
the edge bands 5 of the stiles and rails 1 are made of high quality
wood, for instance red oak; the main body 7 of core panels 2 are
made of artificial board, such as density board; the stickings 3 of
the stiles and rails are made of density board, while the veneers
of the outer parts of the stile rail cores and the stickings are of
red oak. Since the stickings 3 are made of density board instead of
red oak, the amount of high quality red oak used can be cut by
about 30%-50%, thus greatly reduces the production costs.
EXAMPLE 2
[0015] FIG. 3 shows another embodiment of the present invention,
the difference of this example with example 1 lies in the fact that
high quality cherry wood is used in the edge bands 5 of the stiles
and rails, while the stickings 3 and the stile and rail cores 6
adopt the same wood, namely density board, and are integrated into
one part; while the veneers of the outer parts of which is of
cherry wood, which is the same as that of the edge bands of the
stiles and rails. Similarly, the amount of high quality cherry wood
is also saved about 30%-50%, which greatly reduces the production
costs.
EXAMPLE 3
[0016] The outer part of the wooden door in accordance with the
present invention uses the same high quality veneers as that of the
edge bands of the stiles and rails. Firstly, apply evenly resin
glue, for instance urea formaldehyde or water based glue, on one
side of the high quality veneers, then paste it onto the surface of
the stickings which is previously applied with resin glue, after
that put the wooden door into a tamping machine (Model MGZ2500,
Shanghai Xinguo Science and Technology Industrial Co., Ltd.) having
the same shape as the irregular surface of sticking profile, the
temperature is adjusted to 60.about.120.degree. C., and the
pressure to 5.about.15 kg/cm.sup.2, applying the pressure for
2.about.3 minutes.
