Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to a knockdown
aluminum-made floorboard. Two opposite sides of the floorboard are
respectively formed with insertion structures for fixedly engaging
with the insertion structure of an adjacent floorboard.
[0002] FIG. 7 shows a conventional knockdown wooden floorboard. Two
sides of the floorboard 5 are respectively formed with lengthwise
extending tenon 51 and mortise 52. By means of inserting the tenon
51 into the mortise 52, the adjacent floorboards 5 can be
sequentially assembled into a predetermined area.
[0003] However, the tenon 51 can be simply inserted into the
mortise 52 without being fixed. Moreover, the wooden floorboard 5
contains water so that the tenon 51 and mortise 52 tend to deform.
As a result, it will be impossible to snugly insert the tenon 51
into the mortise 52. Therefore, when working on the wooden
floorboard 5, nails 6 or an adhesive is often used to help in
connecting the wooden floorboards 5 with one another. This leads to
inconvenience in working and the adhesive will result in
contamination of the environment. Furthermore, the wooden
floorboard 5 lacks fireproof effect.
[0004] In order to achieve fireproof effect, the floorboard can be
made of aluminum. The aluminum floorboards are generally fixed by
screws. This is similar to the measure used in fixing an aluminum
window frame 7 as shown in FIG. 8. However, such fixing measure
results in inconvenience during working. Also, the exposed screws
will ruin the appearance of the floorboard. Therefore, it is
necessary to provide an aluminum floorboard, which can be more
conveniently and firmly fixed and assembled.
SUMMARY OF THE INVENTION
[0005] It is therefore a primary object of the present invention to
provide a knockdown aluminum-made floorboard, which is integrally
formed by way of aluminum extrusion. The aluminum-made floorboard
has a hollow main body. Two opposite sides of the main body are
respectively formed with a projecting plate and two wing plates
horizontally extending in lengthwise direction. A front end of the
projecting plate is formed with projections. The two wing plates
define a receptacle having a front opening. The opposite inner
sides of the front opening are respectively formed with two stop
sections. When assembled, the projecting plate of one floorboard is
inserted into the receptacle between two wing plates of another
adjacent floorboard. The projections of the projecting plate are
engaged with the stop sections of the two wing plates, whereby the
adjacent floorboards are fixedly connected.
[0006] It is a further object of the present invention to provide
the above floorboard in which two sides of the top of the
floorboard are respectively formed with outward extending extension
boards. The extension boards serve to prevent the projecting plate
and wing plates from being exposed to outer side. In addition, the
extension boards are adjacent to the extension boards of the
adjacent floorboard so as to minimize the seam between the
floorboards and beautify the appearance thereof.
[0007] It is still a further object of the present invention to
provide the above floorboard, which is made of aluminum material so
as to have fireproof effect.
[0008] It is still a further object of the present invention to
provide the above floorboard in which a facial layer is sprayed on
the surface of the top board of the floorboard. The facial layer
can have wooden stripes to achieve an appearance as a wooden
floorboard.
[0009] The present invention can be best understood through the
following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Please refer to FIGS. 1 and 2. The knockdown aluminum
floorboard of the present invention is integrally formed by way of
aluminum extrusion. The aluminum floorboard has a hollow main body
1 including a top board 11 and a bottom board 12. A facial layer 2
is sprayed on the surface of the top board 11. Two lengthwise sides
of the bottom board 12 are respectively formed with two side walls
13 upward extending to the top board 11. Two sides of the top board
11 connecting with the side walls 13 respectively further have two
outward horizontally extending extension boards 111. Several
reinforcing ribs 14 are disposed between the side walls 13. The
reinforcing ribs 14 are perpendicularly connected between the top
board 11 and bottom board 12 of the main body 1. The middle section
of one side wall 13 of the main body 1 has a projecting plate 15
extending in lengthwise direction. The middle section of the other
side wall 13 has two wing plates 16 extending in lengthwise
direction. The projecting plate 15 and wing plates 16 oppositely
horizontally outward protrude from the side walls 13.
[0019] The front end of the projecting plate 15 is formed with two
projections 151 which respectively upward and downward project. The
two projections 151 via two forward obliquely extending guide
slopes 152 adjoin with each other.
[0020] The two wing plates 16 define a receptacle 162 therebetween
and the receptacle 162 has a front opening 161 between two free
ends of the two wing plates 16. The opposite inner sides of the
front opening 161 are respectively formed with two stop sections
163. Each stop section 163 has a dent 164 adapted to the projection
151 of the projecting plate 15.
[0021] Referring to FIGS. 3 to 6, when assembling the present
invention, the projecting plate 15 of the floorboard is inserted
into the receptacle 162 between two wing plates 16 of an adjacent
floorboard. The guide slopes 152 of front end of the projecting
plate 15 are inlaid in the opening 161 of the receptacle 162 to
stretch open the opening 161. Therefore, the projections 151 of the
projecting plate 15 are engaged with the stop sections 163 of the
two wing plates 16 and locked in the dents 164. Accordingly, the
adjacent floorboards are fixedly connected with each other and
multiple floorboards can be sequentially assembled into a
predetermined area.
[0022] The projecting plate 15 of the floorboard is inserted into
the receptacle 162 between two wing plates 16 of the adjacent
floorboard. Therefore, it is unnecessary to additionally use nails
or an adhesive to fix the adjacent floorboards. This makes it
convenient to assemble the floorboards. Moreover, the floorboard is
made of aluminum by extrusion so that the manufacturing procedure
is simplified and the projecting plate 15 and the wing plates 16
are not subject to deformation. Accordingly, the floorboards can be
easily and firmly assembled.
[0023] Furthermore, the outward extending extension boards 111 of
two sides of the top board 11 serve to prevent the projecting plate
15 and wing plates 16 from being exposed to outer side. In
addition, the extension boards 111 correspond to the extension
boards 111 of the adjacent floorboard so as to minimize the seam
between the floorboards. Therefore, after assembled, the floor has
better appearance. The facial layer 2 sprayed on the surface of the
top board 11 of the floorboard can have wooden stripes to achieve
an appearance as wooden floorboard.
[0024] Besides, the aluminum-made floorboard has fireproof
effect.
[0025] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. Many
modifications of the above embodiments can be made without
departing from the spirit of the present invention.
