Abstract
A support frame is intended to support the decorative sheet product and is formed of a plurality of longitudinal elements and horizontal elements, which are in turn formed of a plurality of base portions and main bodies. The base portions are provided with a protrusion and a recess opposite in location to the protrusion, and two slots opposite in location to each other. The base portions are joined together by the mortise-tenon joints to form the longitudinal elements. The main bodies are provided with two protruded blocks opposite in location to each other and are arranged in alignment such that the protruded blocks are received in the slots of the base portions of the longitudinal elements, and that the main bodies form the horizontal elements perpendicular to the longitudinal elements.
Description
FIELD OF THE INVENTION
The present invention relates generally to a decorative product, and more particularly to a support frame of the decorative sheet product.
BACKGROUND OF THE INVENTION
The construction of a ceiling makes us of a support frame which is fastened with the top of a structure for supporting the ceiling sheet product in conjunction with the fastening nails. The use of the conventional support frame results in a substantial decrease in the space between the ceiling and the floor. In addition, the conventional support frame takes up a large storage space.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide the decorative sheet product with a support frame free from the deficiencies of the conventional support frame described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a support frame comprising a plurality of longitudinal elements and horizontal elements perpendicular to the longitudinal elements. Each longitudinal element has a base portion which is provided with two slots opposite to each other and extending along the direction of the longitudinal axis of the base portion. The base portion is provided at one end thereof with a protrusion, and at other end thereof with a recess
28
complementary in shape to the protrusion. Each horizontal element has a main body which is provided at both ends thereof with a protruded block. The longitudinal elements and the horizontal elements are joined together to form the support frame in conjunction with the protrusion and the recess of the longitudinal elements, the protruded block of the horizontal elements, and the slots of the longitudinal elements.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
shows a perspective view of a preferred embodiment of the present invention.
FIG. 2
shows a perspective view of a longitudinal element of the preferred embodiment of the present invention.
FIG. 3
shows a perspective view of a horizontal element of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
As shown in all drawings provided herewith, a support frame
10
of the present invention is used in supporting the decorative sheet product and is formed of a plurality of longitudinal elements
12
and horizontal elements
14
perpendicular to the longitudinal elements
12
. The longitudinal elements
12
are provided with a base portion
22
which is provided in two opposite longitudinal sides thereof with a slot
24
of a length and extending along the direction of the longitudinal axis of the base portion
22
. The base portion
22
is further provided at one longitudinal end thereof with a protrusion
26
, and at other longitudinal end thereof with a recess
28
complementary in shape to the protrusion
26
. The horizontal elements
14
are provided with a rectangular main body
30
which is in turn provided at both longitudinal ends thereof with a protruded block
32
complementary in shape to the slot
24
. The main body
30
is corresponding in thickness to the base portion
22
.
The support frame
10
of the present invention is formed of a plurality of the longitudinal elements
12
and the horizontal elements
14
. Each longitudinal element
12
is formed of a plurality of base portions
22
, which are joined together end to end such that the protrusion
26
of one base portion
22
is received in the recess
28
of another base portion
22
. Each horizontal element
14
is formed of a plurality of the main bodies
30
which are arranged in alignment with one another and are perpendicular to the longitudinal elements
12
such that the protruded blocks
32
of the main bodies
30
are received in the slots
24
of the base portions
22
of the longitudinal elements
12
.
Both longitudinal elements
12
and the horizontal elements
14
of the support frame
10
of the present invention are formed of a plurality of building blocks, such as the base portions
22
and the main bodies
30
. As a result, the support frames
10
of various specifications can be constructed on the construction site. In addition, the base portions
22
and the main bodies
30
can be easily stored or shipped.
The longitudinal elements
12
and the horizontal elements
14
of the present invention are formed of building blocks by the mortise-tenon joints, which may be further reinforced by the fastening nails (not shown in the drawings).
The embodiment of the present invention described above is to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. For example, the cross-sectional shapes of the protrusion
26
, the recess
28
, the slot
24
, and the protruded block
32
of the present invention may be rectangular or of any geometric form. The present invention is therefore to be limited only by the scopes of the following appended claims.
Claims
- 1. A support frame of a construction sheet product, said support frame comprising a plurality of longitudinal elements and horizontal elements perpendicular to said longitudinal elements, said longitudinal elements being formed of a plurality of base portions, with each base portion having two longitudinal sides and two longitudinal ends, each of said longitudinal sides being provided with a slot, one of said longitudinal ends being provided with a protrusion, and the other of said longitudinal ends being provided with a recess complementary in shape to said protrusion, whereby said base portions are joined together end to end such that said protrusion of one of said base portions is received in said recess of another one of said base portions, said horizontal elements being formed of a plurality of main bodies, with each having two protruded blocks complementary in shape to said slots of said base portions, said main bodies being arranged in alignment such that said protruded blocks of each of said main bodies are received in said slots of said base portions, and wherein said protrusion and said recess of each of said base portions are located at the center of the longitudinal ends of each of said base portions.
- 2. The support frame as defined in claim 1, wherein said protrusions, said recesses, said slots, and said protruded blocks have a rectangular cross section.
