DETAILED DESCRIPTION OF THE INVENTION
[0017] The aforementioned and further advantages and features of
the present invention will be understood by reference to the
description of the preferred embodiment in conjunction with the
accompanying drawings where the components are illustrated based on
a proportion for explanation but not subject to the actual
component proportion.
[0018] Referring to FIG. 1 to FIG. 4, the combination frame
material 1 provided by the present invention comprises an outer
frame 10 and an inner frame 20.
[0019] The outer frame 10 is made of plastic-wood material in strip
shape. The raw material of the outer frame 10 is an extrusion of a
mixture mainly of thermoplastic and natural fiber (such as wood
powder, rice hull, wheat straw, and bamboo powder). The outer frame
10 has an outer side and an inner side, while the inner side is
provided with a wood-like pattern, and has two parallel combining
grooves 11, 12 with a middle pillar 13 therebetween for dividing
the two combining grooves 11, 12. The combining grooves 11, 12 are
provided with a first inner wall 111, 121 and a second inner wall
112, 122 oppositely disposed against the first inner wall 111, 121,
respectively, while the first inner walls 111, 121 and the second
inner walls 112, 122 are provided with at least an inclining
concave strip 14, respectively. In the preferred embodiment of the
present invention, the first inner wall 111, 121 has two concave
strips 14, respectively, and the second inner wall 112, 122 has one
concave strip 14, respectively.
[0020] The combining grooves 11, 12 further have a bottom wall 113,
123, respectively, while two sides of the two bottom walls 113, 123
are provided with a corner recess 15, respectively, which is in a
concave-arc shape, thereby preventing the outer frame 10 to deform
when exposed to heat. Furthermore, two sides of the outer frame 10
are provided with a connect groove 16, respectively, while a
connector 17 (as shown in FIG. 5) is received in the connect groove
16, so as to connect another outer frame 10. The second inner walls
112, 122 of the combining groove 11, 12 are oppositely disposed at
the two outer faces of the middle pillar 13, respectively.
[0021] The inner frame 20 is made of an aluminum extrusion strip,
having two parallel combining parts 21, 22 for being received in
the two combining grooves 11, 12. A pillar groove 23 is disposed
between the two combining parts 21, 22 for receiving the middle
pillar 13. Therein, the combining parts 21, 22 are provided with a
first outer wall 211, 221 and an opposite second outer wall 212,
222, respectively. The first outer wall 211, 221 are provided with
at least one convex strip 24, respectively, for matching the
concave strip 14. In the preferred embodiment of the present
invention, each of the first outer walls 211, 221 has two convex
strips 24.
[0022] Furthermore, the first outer wall 211, 221 and the second
outer wall 212, 222 are connected by a combining wall 213, 223,
respectively, such that the combining wall 213, 223, the first
outer wall 211, 221, and the second outer wall 212, 222 of the
inner frame 20 form a U-shaped structure. When the inner frame 20
is combined with the outer frame 10, the combining wall 213, 223
contact the bottom walls 113, 123, respectively, whereby the inner
frame 20 and the outer frame 10 are combined with each other in an
identical direction. In other words, the openings of the inner
frame 20 and the outer frame 10 face the same direction,
facilitating the combining process of the inner frame 20 and the
outer frame 10.
[0023] Also, a slope 25 is disposed at the junctions of the
combining wall 213, 223 connected with the first outer wall 211,
221 and with the second outer wall 212, 222, respectively, for
correspondingly overlapping the corner recess 15. The second wall
212, 222 of the combining part 21, 22 is oppositely formed at the
two inner faces of the pillar groove 23, respectively.
[0024] Referring to FIG. 4, during the combination, the inner frame
20 is allowed to be fixed on the floors, walls, or other locations
in advance by use of fasteners (not shown in the drawings), with
the combining parts 21, 22 thereof facing outward. Next, the outer
frame 10, with the combining grooves 11, 12 respectively facing the
combining parts 21, 22, is tapped inward to couple the inner frame
20, so that the match of the convex strips 24 and the concave
strips 14 prevents the inner frame 20 and the outer frame 10 from
departing from each other. Also, due to the openings of the inner
frame 20 and the outer frame 10 facing the same direction, the
inner frame 20 and the outer frame 10 are able to be combined
efficiently, so as to prevent aligning difficulty thereof. In
addition, the slope 25 provides the convenience of the outer frame
10 smoothly coupling the inner frame 20, so that the outer frame 10
is allowed to efficiently coupling the inner frame 20 even if the
inner frame 20 is in an expanding status. Also, the middle pillar
13 between the combining groove 11 and the combining groove 12 is
received in the pillar groove 23, whereby the combining walls 213,
223 contact the bottom wall 113, 123, respectively. As a result,
when the outer frame 10 bears an external force, the middle pillar
13 is able to disperse the external force for achieving a better
support effort, so that the outer frame 10 is prevented from deform
due to force bearing, thus providing a higher structural strength
to the combination frame material 1 of the present invention.
[0025] Furthermore, even if the two combining parts 21, 22 of the
inner frame 20 deform to be narrowed, the two slopes 25 thereof are
able to push toward the middle pillar 13, whereby the pillar groove
23 clamps the middle pillar 13 with higher tightness. The concave
strips 14 on the two sides of the middle pillar 13 allow the outer
frame 10 to be partially coupled and engaged, so as to provide a
buffering effect, thereby mitigating the deformation of the outer
frame 10 and realize a higher structural strength of the
product.
[0026] With the foregoing configuration, the inner frame 20 is able
to be fixed at a predetermined position in advance. The outer frame
10 is provided with a wood-like pattern to achieve an appearance
variety, and at the same time to solve the disadvantages of a real
wood material consuming natural resource and of a metal material
being aesthetically stiff and heat absorbing easily.
[0027] Referring to FIG. 5, with the foregoing configuration, the
combination frame material 1 in accordance with the present
invention is allowed to be applied on floors.
[0028] Referring to FIG. 6, with the foregoing configuration, the
combination frame material 1 in accordance with the present
invention is allowed to be applied on walls.
[0029] Referring to FIG. 7, with the foregoing configuration, two
combination frame materials 1 in accordance with the present
invention are allowed to be combined back to back by use of the two
inner frames 20 thereof, with the two outer frames 10 thereof are
combined to the two inner frames 20 afterward, respectively, so as
to form a column 2.
[0030] With the description above, the combination frame material
provided by the present invention is allowed to be applied on
scopes of floors, walls, or columns. The outer frame and the inner
frame models are possible to be molded for lowering cost of
manufacturing. Furthermore, when the outer frame and the inner
frame are being combined, the two respective openings face the same
direction, such that the combination between the two frames is
accelerated, thus facilitating the constructional decoration.
Therefore, the combination frame material of the present invention
is applicable in various scopes.
[0031] Although particular embodiments of the invention have been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
