[0002] This application claims the priority benefit of Application
No. 098124495 file in Taiwan on Jul. 21, 2009.
FIELD OF THE INVENTION
[0003] The present invention relates to composite furniture and
particularly to assembled furniture made of paper.
BACKGROUND OF THE INVENTION
[0004] There is a growing awareness of environmental protection in
the modern society. In many people's mind the good quality of life
is no longer simply pursuing fancy life style or material opulence,
but trying to make life more meaningful. Many people nowadays have
changed their lifestyle from using expensive goods to those
beneficial to the general public, and try to live in a lifestyle
that stresses on coexistence of human being and environment.
[0005] The conventional furniture, in order to meet consumers'
requirements in assembly, disassembly, storage or flexibility in
use, generally is made of materials that consume a great amount of
wood, metal or plastic materials. And greater sturdiness and
durability are the main objective.
[0006] However, while wood, metal and plastic materials are sturdy
and durable, they cause great harm to environments during
production. Wood is natural material, but it grows slowly. During
fabrication of wooden furniture inadvertent impact could easily
take place that results in scrapes or damages, and spoils the total
appeal. Moreover, mending the damaged surface of wooden material is
difficult, hence it often happens that the entire set of furniture
has to be replaced that causes even more waste of the wood. The
steel is heavier in weight and costs more in terms of fabrication,
construction and transportation, and also is more difficult to
recycle when replacement takes places, hence creates a great impact
to the environment. Plastics are easier to form into desired
shapes, but also generate a great deal of pollution during
production, and decomposition is difficult after discarded, or
create even more environmental contamination problems such as air
or water pollution if they are treated by burning.
[0007] There are furniture made of corrugated paper board on the
market, such as chairs or cabinets. They are generally lighter than
the furniture made of woods or steel, and less likely to create
environmental pollution. But they also have shortcomings, such as
deficient in structural strength and easily warp and deform when
subject to heavy loading.
[0008] U.S. Pat. No. 5,423,604 discloses an eco-friendly cabinet
frame structure which comprises a plurality of coupling tubes, a
plurality of panels and a plurality of connector sets that are made
from recyclable plastic material. Each coupling tube has a groove
on the outer side. The coupling tubes are interconnected via the
connector sets. The panels are wedged in the grooves of the
coupling tubes, thereby form the eco-friendly cabinet frame
structure. However, the coupling tubes, panels and connector sets
could be thrown away or burned by people maliciously, thus still
create the problems of environmental pollution and
non-decomposition.
[0009] Another U.S. Pat. No. 4,192,562 discloses a composite
storage rack consisting of flat panels and ribs that use
three-layer fiber boards with a middle layer made of kraft paper
mixed with resin. But the fiber boards are formed by compression of
wooden fibers at high pressure, hence are heavier in weight.
Moreover, to make the fiber boards moisture-resistant is expensive.
All this creates a great burden to consumers in terms of
transportation and cost.
SUMMARY OF THE INVENTION
[0010] The primary object of the present invention is to solve the
disadvantages of the conventional paper furniture in material and
technique by providing novel paper furniture assembled by
connection tubes and spacers formed by compression of multi-layer
spool paper and multi-layer kraft paper.
[0011] To achieve the foregoing object, the present invention
provides paper-made composite furniture which comprises at least
two connection tubes and at least one spacer that are coupled
together. Each connection tube is a hollow tube with an inner side
made of spool paper and an outer side made of kraft paper. The
connection tube has at least one latch groove. The spacer is a
solid panel made of the spool paper with the outer side coated by
the kraft paper. The spacer has two sides wedged respectively in
the latch grooves of the connection tubes.
[0012] By means of the structure set forth above, the invention
provides many advantages, notably:
[0013] 1. The paper-made composite furniture is made of paper,
hence can be recycled easily without generating environmental
pollution.
[0014] 2. The invention employs the spool paper which is lighter in
weight and sturdy, hence can be transported easily and save
manpower, and also is easier to fabricate and construct, thus can
reduce the cost.
[0015] 3. The invention also uses the kraft paper which can be set
with colors or patterns or texts, and can be arranged in various
assembly types to form the paper furniture in diversified styles to
improve visual appeal and enhance ornamental efficacy. Moreover,
the multi-layer spool paper and kraft paper formed by pressing can
provide improved water-proof effectiveness.
[0016] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] Please referring to FIGS. 1 and 2, the paper-made composite
furniture of the invention comprises at least two connection tubes
2 and at least one spacer 3. Each connection tube 2 is a hollow
tube with an inner side made of spool paper and an outer side made
of kraft paper. Each connection tube 2 has at least one latch
groove 21, and an inner extension 222 at the inner side of the
latch groove 21 and an outer extension section 221 at the outer
side of the latch groove 21. The inner extension 222 is formed at a
width greater than that of the outer extension 221. The spacer 3 is
a solid panel made of the spool paper coated by the kraft paper on
the outer side thereof. The spacer 3 has two sides 31 wedged
respectively in the corresponding latch grooves 21 of the
connection tubes 2 to form secure latching.
[0024] The spool paper mentioned herein also is called sand tube
paper or bobbin fiber paper that is commonly used for making
bobbins in textile industry. It is light weight, abrasion-resistant
and water-proof in characteristics, hence can improve loading
capability and less likely deforms when used to make paper
furniture. Since the surface of the spool paper does not absorb
water easily, moisture is less likely to enter the inner layer even
if it is placed in a damp location, thus can prevent moisture from
seeping in and avoid decrease of structural strength of the paper
furniture. The kraft paper also is water-proof and has a smooth
surface, and also has advantages of easily printed with patterns
and coloration, hence can spruce up the substance and appearance of
the entire furniture to make it more appealing. The connection
tubes 2 and the spacer 3 can be formed respectively by pressing
multi-layer spool paper and multi-layer kraft paper. The spool
paper and the kraft paper thus formed can withstand pressure and
has a higher density, hence can prevent moisture from seeping
inside the structure of the paper-made composite furniture of the
invention. As a result, the furniture can provide improved support
and water-proof efficacy.
[0025] By means of the elements set forth above, the connection
tubes 2 can be arranged in a spaced manner with the latch grooves
21 facing inward corresponding to each other, then the two sides 31
of the spacer 3 can be wedged in the latch grooves 21 to form a
partition-like composite furniture 1.
[0026] In another embodiment of the invention, the connection tube
2a has two latch grooves 21a on the abutting outer sides that can
be incorporated and assembled with the spacers 3 to form various
types of furniture, as shown in FIGS. 3 and 4. By interconnecting
the connection tubes 2 and 2a with the spacers 3 wedged in the
latch grooves 21 and 21a of the connection tubes 2 and 2a, varying
styles of furniture 1A such as chairs can be formed. As the inner
extension 222a of the connection tube 2a is formed at a width
greater than that of the second extension 221a, the spacer 3 has a
greater loading capability in the direction perpendicular to the
inner extension 222a. Moreover, the second extension 221a of the
connection tube 2a and the coupled spacer 3 form a smaller gap at
the upper side of the composite furniture 1A, hence an additional
spacer 3a can be disposed above the spacer 3 to form a smooth
surface to provide more comfortable sitting and a neat
appearance.
[0027] The composite furniture 1 of the invention further includes
a plurality of corner joints 4 to couple with the connection tubes
2 as shown in FIGS. 5 and 6. The connection tubes 2 and 2a are
arranged in various styles and coupled with the corner joints 4 to
form secure latching and positioning, and the spacers 3 are wedged
in the latch grooves 21 and 21a of the connection tubes 2 and 2a,
thereby other types of composite furniture 1B and 1C such as
cabinets or tables can be formed.
[0028] The connection tubes 2 and 2a and the spacers 3 can be
assembled with the corner joints 4 to form various configurations
and styles according to requirements when in use. The spool paper
is lighter in weight and sturdy, hence is easier to transport and
assemble and can save manpower, and also can be recycled without
creating environmental pollution. Moreover, the kraft paper can be
formed with different colors or printed with varying patterns or
texts on the surface thereof, thus varying styles of paper-made
composite furniture can be formed with greater visual appeal and
ornamental efficacy.
