Description

SIMPLE-FRAME INTERIOR FLOORING MATERIAL
FOR CONSTRUCTION
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is related to a simple-frame interior flooring
material for construction installed at the floor of buildings in which
human beings or animals live.
Descr ption of the Prior Art
Conventional flooring materials for construction have various sizes
and are largely classified into hard flooring materials. Generally,
synthetic resin plates or tiles (glass), wooden plates, thin stone plates,
the mixture of synthetic resins and plaster, etc. are used for hard
flooring materials, while vinyl sheets, the mixture of vinyls and synthetic resins, that of vinyls and plastics, oiled floor papers, carpets, etc. are
used for soft flooring materials. However, conventional flooring materials
have been disadvantageous in that it is almost impossible to separate again
and move once they are installed at the floor by using a bond, strong
adhesive, cement, etc., and their unit prices are very high as they are of
high class. They have been also disadvantageous in that their construction
is not easy, partial replacement is very difficult, expenses accompanied by
the replacement are high, and their cushioning function is not superior
relatively except for carpets.
In the meantime, polyurethane foaming flooring materials or sponge
materials having the size of 50cm to lm widthwise and lengthwise have been
produced. However, these are used not by fixing them to the floor by means
of an adhesive, etc., but by simply spreading and connecting them on the
floor. That is, they have been problematic in that their connection and
fixing are not easy when they are spread on the floor since there is no
means of connecting them together, and particularly, their appearance has
not been superior since their connection portions (touching boundary lines)
are exposed externally, and the connection portions are easily separated by
a small amount of impact. Also, it has been disadvantageous in that dust
from the floor flies up through cracks of the connection portion if impact is imposed on from the upper portion, and it is difficult to clean dust
between connection portions, other foreign materials, etc. Further, the
above flooring materials have been disadvantageous in that they are easily
scratched or torn out as their surface is weak, and they do not have
beautiful colors. Therefore, they have not been highlighted as flooring
materials for construction, but have been partially used in a simple way in
kindergartens, playing rooms, etc. Their connection methods include a
method of attaching by using tapes or bond, a method of inserting into each
other by forming rugged portions around four side frames as shown in Figure
1, etc. However, it has not been reasonable since the connection state is
not solid and the work quality is inferior. It has been also Inconvenient
to move to another location if flooring materials are attached to the floor
by using a bond.
The present invention is to resolve unreasonable problems related to
conventional interior flooring materials as described in the above.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an
economical and very reasonable way of using simple-frame interior flooring materials for construction by integrating the upper surface of flooring
materials made of cushioning materials with carpets, wooden plates, stone
plates, tiles, and oiled floor papers and installing simply at interior
floors of a place where human beings or animals live so that shock and
noise are absorbed, and separation, moving, and installing are facilitated
in case of moving or changing the location of installation.
Another object of the present invention is to provide simple-frame
interior flooring materials for construction, which can prevent penetration
of dust or foreign materials into the connection portions of flooring
materials after construction by not having connection portions of flooring
materials exposed externally.
Still another object of the present invention is to provide
simple-frame interior flooring materials for construction, which can be
used very reasonably from the point of view of economy by reducing
additional expenses connected to construction since only damaged portions
can be simply replaced in case of partial damage in the present invention.

DETAILED DESCRIPTION OF
PREFERRED EMBODIMENTS OF THE INVENTION
Figure 1 is a partially cut perspective view showing the first
preferred embodiment of the present invention. Figure 2 is ϊ plan view
showing the installation state of the first embodiment of the present invention. And Figure 3 is an enlarged cross-sectional view of the major
portion of the first preferred embodiment of the present invention.
It is seen from the above figures that the rugged portion (4) which
can connect cushioning materials (2) consecutively is formed around four
edges of cushining materials (2) which are under the surface layer (3) of
the floor materials (1). As to flooring materials (1) which are formed on
top by integrating the surface layer and cushining materials (2) in the
same size, squared surface layer (3) is integrated with the above
cushioning materials (2) at one side eccentrically regardless of the rugged
portion (4) of cushining materials (2) forming the flooring matrials (1).
At this time, cushioning materials (2) can be connected in four directions
by the rugged portion (4) and the connection portion of cushioning
materials are covered by the installation interval (LI) of the surface
layer (3) by integrating the cushioning materials (2) and surface layer (3)
while maintaining installation intervals (L, LI).
In the above flooring materials (1), installation intervals (I, LI)
of the cushioning materials (2) and surface layer (3) are produced in the
same size naturally regardless of the number of flooring materials (1).
Various types of materials such as EVA sponge, foam urethane sponge,
rubber, etc. can be used for the above cushioning materials (2), and other types of foamed synthetic resins can be also used for cushioning materials.
For the material of surface layer (3), carpets, wooden plates, stone
plates, tiles, and oiled floor papers can be used. Various kinds of
carpets can be used, and it is preferable to use wooden plates and stone
plates of less than 1 cm thick since they offer a variety of materials.
Glass tiles and oiled floor papers which are manufactured and
commercialized in various forms can be also used. It is natural to apply
the above-described materials to the surface layer (3a) in the second
embodiment of the present invention illustrated below.
In the meantime, Figure 4 is a decomposed perspective view of the
second embodiment of the present invention. Figure 5 is a cross-sectional
view showing the combination state of Figure 4. Figure 6 is the enlarged
cross-sectional view of the major portion of Figure 5. The installation
interval (LI) is formed at one side of the surface layer (3a) of the
flooring materials (la), which are connected to each other by adding an
adhesive means (5) on top of the installation interval (L) of the
cushioning materials (2a) and attaching the installation interval of the
surface layer (3a) on top of the installation interval -'L) of the
cushioning materials (29). That is, when construction is done by spreading
an adhesive agent (6) on top of the above cushioning materials (2a) and attaching again differently formed papers (7) on top of the adhesive agent
(6), the above differently formed papers (7) are peeled off, after which
the installation interval (LI) of the above protection plate (3a) is
attached to the upper surface of the installation interval (L) of the
cushioning materials (2a). Of course, construction can be done by
attaching usual both-side adhesive tapes to the bottom surlace of the
installation interval (LI) of the surface layer (3a) in addition to the
above composition. For harder construction of flooring materials, the
bottom surface of the installation interval (LI) of the surface layer (3a)
may be attached to the upper surface of the installation interval (L) of
cushing materials (2a) by employing the hot-melting method.
In the first embodiment of the present invention, construction is
completed by using and combining the rugged portion (4) of the cushioning
materials (2) in the insertion method as shown in Figure 2. Since anyone
can perform construction simply without separate training, convenience in
construction is further added. At this time, the installation interval of
the surface layer (3) prevents input of foreign materials, dust, etc. into
the connection portion of cushioning materials (2) by covering the
connection portion of cushioning materials (2). And the connection
portions of cushioning materials (2) are not easily separated by impact since they are connected by means of the rugged portion (4), and the entire
cushioning materials (2) are hidden by the surface layer (3). Therefore,
it locks as if only surface layers (3) were constructed on the floor.
Next, in the second embodiment of the present invention, it is
possible to connect flooring materials (la) simply and consecutively by
peeling off differently formed papers (7) on the installation interval (L)
of the above cushioning materials (2a) so that the adhesive agent (6) is
exposed, and attaching the bottom surface of the installation interval (LI)
of the above surface layer (3a) to the adhesive (6) on the installation
interval (L) of cushioning materials (2a).
By constructing the flooring materials of the present invention as
described in the above, it is possible to prevent from being injured when a
person falls down and to reduce shock delivered to the head when walking,
since the flooring materials of the present invention give a feeling of the
floor constructed by the general carpets, wooden plates, stone plates,
tiles, or oiled floor papers, and they have superior cushioning power due
to the combination between cushioning materials and the surface layer.
The thickness of cushioning materials may be determined arbitrarily,
however, preferably it should be 5-10 mm.
Additionally, as reviewed in the above, in the present invention, inasmuch as construction is very easy and is accomplished in a very closely
attached state by the rugged portion (4) or adhesive means (5) of the
cushioning materials, problems such as easy detachment even by impact after
the completion of construction can be resolved at the same time. Further,
another advantage of the present invention is that construction can be done
simply in the same method as described in the above by separating the
rugged pert ion (4) of cushioning materials or simply separating the
installation interval of the surface layer from the adhesive and moving to
another location if it is desired to construct and use flooring materials
in the same method as described in the above and to move and construct
again at another location if necessary.
As described in the above, the present invention is advantageous in
that it has improved cushioning power, sound-proofing ffect, and
temperature-keeping effect due to its dual structural characteristic, as
well as it is very reasonable from the point of view of hygiene since a
phenomenon of inputting dust, foreign materials, etc. can be prevented due
to no cracks generated between the connection portions after construction.
The present invention is also advantageous in that flooring materials are
not easily detached even by impact after construction due to its tight
connection function, construction can be done easily by anyone without need for professional workers, working method is very simple nnd partial
replacement is easy, and construction can be done again by simply moving
once-constructed flooring materials to another location. Further, it is
possible for the present invention to construct in various ways by changing
the color or surface treatment method of the surface layers (3, 3a), to
demonstrate a superior decorative effect, and to attempt high classing of
the quality of the flooring materials particularly without spending too
much money since various types of pictures or patterns can be arranged
arbitrarily. While the invention has been described in terirs of a few
preferred embodiments, those skilled in the art will recognize that the
invention can be practiced with modification within the spirit and scope of
the appended claims.
