lateral bamboo strip are respectively matched into the concave
holes of the chair-leg.
[0009] The lateral bamboo rods of the present invention are fixed
to the chair-leg by using the fixing elements after inserting the
lateral bamboo rods into the concave holes of the chair-leg, and so
as to avoid the separation between the seat and the chair-leg
because of the bearing weight.
[0010] The chair-leg and the armrest made of bamboo material of the
present invention have two legs and two armrest-legs respectively,
and the two legs tilt an angle toward the leaving direction for
each other. The two armrest-legs also tilt an angle toward the
leaving direction for each other.
[0011] The technical measure of the present invention to construct
the seat is utilizing a plurality of lateral bamboo strips to form
a continuous bended shape, and laminating the first bamboo
seat-component and the second bamboo seat-component in parallel
pairs to construct a seat unit. A plurality of lateral bamboo rods
are set between the first bamboo seat-component and the second
bamboo seat-component, and two ends of the lateral bamboo rods are
respectively protruded out of two sides of the seat for a proper
length. The first bamboo seat-component and the second bamboo
seat-component of the seat unit are separated out laminated space
by using the lateral bamboo rods. Therefore, the bamboo seat with
the bamboo chair-back is constructed by nailing each first bamboo
seat-component and each second bamboo seat-component with the
lateral bamboo rods.
[0012] The present invention utilizes good elasticity feature of
the bamboo material and crafted technical art to further combine
the bamboo armrest with the bamboo chair-leg into a one-body
structure, so as to increase the whole strength of the bamboo chair
and make its look-and-feel more delicate. Therefore, the present

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] The detailed explanation of the present invention is
described as following. The described preferred embodiments are
presented for purposes of illustrations and description, and they
are not intended to limit the scope of the present invention.
[0021] The foregoing aspects and many of the accompanying objects,
functions, and advantages of this invention will become more
readily appreciated as the same becomes better understood by
reference to the following detailed description, when taken in
conjunction with the accompanying drawings.
[0022] Firstly, please refer to FIG. 1 to FIG. 3, the bamboo chair
according to the preferred embodiment of the present invention is
formed by a plurality of bamboo components. The bamboo chair
comprises the chair-leg 1 and the armrest 2 with a general -shape
formed by bending the bamboo material; and the seat 3 formed by
continuous bending the bamboo material. The chair-leg 1 and the
armrest 2 are combined to form a one-body armrest-leg unit, and the
seat 3 is fixed between two armrest-leg units.
[0023] Next, the chair-leg 1 of the present invention is formed by
bending the bamboo material to have a general -shape as shown in
FIG. 5A and FIG. 5B. The chair-leg 1 has the legs 11 faced each
other on two opposite sides; and the leg-connection portion 12
positioned thereon to connect two legs 11. The two legs 11 may tilt
an angle toward the leaving direction for each other, so as to
enlarge the support area between the lower ends of the legs 11 and
the ground. And, the side surface of the chair-leg 1 may set with a
plurality of concave holes 13.
[0024] Then, the structure of the armrest 2 for the present
invention is also formed by bending the bamboo material to have a
general -shape as shown in FIG. 6A to FIG. 6C. The armrest 2 has
the armrest-legs 21 faced each other on two opposite sides; and the
armrest-leg-connection portion 22 positioned thereon to connect two
armrest-legs 21. The two armrest-legs 21 may tilt an angle toward
the leaving direction for each other, so as to enlarge the support
area between the lower ends of the armrest-legs 21 and the ground.
And, the overall height of the armrest 2 is higher than which of
the chair-leg 1. Preferably, the tilted angle of the armrest-legs
21 is the same as which of the legs 11 of the chair-leg 1. And, the
size of the opposite inner sides of the armrest-legs 21 is
preferably the same as which of the opposite outer sides of the
legs 11 of the chair-leg 1.
[0025] Through the structure of the chair-leg 1 and the armrest 2
described above, the implemented way of the present invention for
combining the chair-leg 1 with the armrest 2 into a one-body is to
combine the two opposite outer surfaces of the legs 11 and the two
opposite inner surfaces of the armrest-legs 21 so as to form a
one-body armrest-leg unit.
[0026] Furthermore, as shown in FIG. 4 and FIG. 7, the
above-mentioned armrest-leg unit needs to cooperate with the seat 3
for practical usage. The seat 3 in the embodiment of the present
invention is also made of bamboo material, which comprises a
plurality of lateral bamboo strips formed in a continuous bended
shape to construct the bamboo seat. The first bamboo seat-component
31 A and the second bamboo seat-component 31B are laminated in
pairs to construct a seat unit 31. The seat units 31 are paralleled
lineup, and a plurality of lateral bamboo rods 4 are set between
the first bamboo seat-component 31A and the second bamboo
seat-component 31B. And, two ends of the lateral bamboo rods 4 are
respectively protruded out of two sides of the seat 3 for a proper
length. The first bamboo seat-component 31A and the second bamboo
seat-component 31B of the seat unit 31 are separated out laminated
space by using the lateral bamboo rods 4. Then, the bamboo seat 3
with the bamboo chair-back is constructed by using the fixing
elements 5 to nail each first bamboo seat-component 31A and each
second bamboo seat-component 31B with the lateral bamboo rods
4.
[0027] The assembly way of the seat 3 with two armrest-leg units is
direct inserting the lateral bamboo rods 4 positioned in two sides
of the seat 3 into the concave holes 13 of the chair-leg 1 and
fixing them. Preferably, the tight fastening is applied between the
two ends of the lateral bamboo rods 4 and the concave holes 13.
Moreover, the lateral bamboo rods 4 may be further drilled holes in
the proper positions near their free ends. And, the inner surfaces
of the chair-leg 1 may be drilled corresponding holes in the proper
positions to make the corresponding holes correspond to each other
after the lateral bamboo rods 4 entering into the concave holes 13.
Then, the complete fixing between the lateral bamboo rods 4 and the
chair-leg 1 is obtained by using the fixing elements 5 to nail into
the corresponding holes. Accordingly, the better load-bearing
strength and the one-body look-and-feel are achieved by the present
invention.
