Claims
What is claimed is:
1. A coupling cushiony flooring having a rectangular shape
comprising: lower steps 12 formed along two sides of the flooring;
an adhesive 16 coated on an upper surface of the lower steps; a
release paper 18 attached to the adhesive; and upper steps formed
along two sides of the flooring.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a cushiony flooring capable
of being laid on various living facilities or accommodation
structures to provide a cushion function.
[0003] 2. Background of the Prior Art
[0004] Generally, in playing facilities of babies or various
gymnasiums, flooring having a cushion function is laid on an indoor
or outdoor floor thereof for the purpose of shock absorption and
soundproof. In these days, various floorings are used in various
public facilities such as office, assembly hall and so forth.
[0005] Polyurethane or sponge is mainly used as material of such
flooring. This is manufactured to have constant dimensions, and is
transferred to a location. And then, the flooring is unfolded on
the floor, and simultaneously is coupled to each other by means of
various coupling means. As one example of the coupling means,
coupling recesses are formed at an edge of the flooring such that
abutted portions of the flooring are complementarily inserted into
each other. This manner has a drawback that the coupled portions
are easily detached if shock is applied thereto.
[0006] Meanwhile, in order to solve the above drawback, another
means has been proposed by Korean Unexamined Utility Model
Publication No. 1999-22352, entitled "Simplified indoor flooring".
According to the publication, a surface layer is positioned on the
cushion constituting the flooring, with the position of the surface
layer being slightly staggered to that of the flooring. The surface
layer has the same dimensions as the flooring, and is adhered to
the flooring by means of an adhesive. After carrying out the
construction, a large gap does not occur in the coupled portion.
Accordingly, even though the shock is applied to the coupled
portion, the coupled portion is not easily widened, and alien
substances come into or out from the gap of the coupled portion.
However, there are many problems at carrying out the
construction.
[0007] Specifically, according to the publication, the process of
adhering the cushion and the surface layer by means of the adhesive
is not precisely performed, and many workers are required for
performing the process. Accordingly, when the flooring is arranged
on the surface of the bottom and is coupled to each other, the
coupling portions are not constant and the appearance is not well,
thereby unsatisfying the construction.
[0008] In addition, the coupled portion of the cushion and the
surface layer is easily detached by the continuous shock.
SUMMARY OF THE INVENTION
[0009] Accordingly, the present invention is directed to a cushiony
flooring that substantially obviates one or more problems due to
limitations and disadvantages of the related art.
[0010] An object of the present invention is to provide a cushiony
flooring capable of being easily manufactured and constructed, with
durability of a coupled portion thereof improved.
[0011] To achieve the object and other advantages, according to one
aspect of the present invention, there is provide a coupling
cushiony flooring having a rectangular shape comprising: lower
steps formed along two sides of the flooring; an adhesive coated on
an upper surface of the lower steps; a release paper attached to
the adhesive; and upper steps formed along two sides of the
flooring.
[0012] It is to be understood that both the foregoing general
description and the following detailed description of the present
invention are exemplary and explanatory and are intended to provide
further explanation of the invention as claimed.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The accompanying drawings, which are included to provide a
further understanding of the invention and are incorporated in and
constitute a part of this application, illustrate embodiment(s) of
the invention and together with the description serve to explain
the principle of the invention. In the drawings:
[0014] FIG. 1 is a perspective view of a cushiony flooring
according to one preferred embodiment of the present invention;
[0015] FIG. 2 is a cross-sectional view showing the installed state
of the cushiony flooring of the present invention;
[0016] FIG. 2a is a partially enlarged view of the cushiony
flooring of FIG. 2; and
[0017] FIG. 3 is a top plan view showing a coupling state of a
cushiony flooring of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] A preferred embodiment according to the present invention
will now be explained with reference to the accompanying
drawings.
[0019] FIG. 1 is a perspective view of an assembled state of a
cushiony flooring according to one preferred embodiment of the
present invention, in which the floorings 1 having a constant
shape, i.e., a rectangular shape, are coupled to each other along
two sides thereof.
[0020] As shown in FIG. 1, the rectangular cushion 10 may be mainly
made of EVA sponge, polyurethane foam or rubber. One cushion is
formed with lower steps 12 along two sides, while the other cushion
is formed with upper steps along two sides which are symmetrical to
the lower steps. The flooring having the above structure may be
manufactured through a molding by once. The upper surface of the
lower step 12 is applied with an industrial adhesive, and a release
paper 18 is attached to the adhesive.
[0021] Specifically, the lower step 12 is strongly adhered to the
upper step 14 by means of the adhesive 16 formed on the lower step.
The remaining floorings are correctly arranged as the
above-mentioned manner.
[0022] The cushion 10 has a transferred printing layer 22 of
various colors, such as design, logo or symbol, on the upper
surface thereof. The transferred printing layer 22 may be formed by
means of a method of attaching a pattern paper, as well as the
transferring method using a film. In order to protect the
transferred printing layer 22, a transparent urethane coating
solution may be sprayed on the upper surface of the transferred
printing layer to form a coating layer 20.
[0023] With the above description, the flooring of the present
invention is manufactured through a single machining process and is
coupled and secured to each other by means of the adhesive.
According to the present invention, the flooring having a uniform
quality may be manufactured in a mass production. The construction
is easily performed, and time and process for constructing the
flooring are decreased, thereby saving the personal expenses. Since
the appearance thereof is improved because of the transferred
printing layer, it is unnecessary to utilize a separate carpet. In
addition the coating layer protecting the surface may improve the
durability thereof.
[0024] The forgoing embodiments are merely exemplary and are not to
be construed as limiting the present invention. The present
teachings can be readily applied to other types of apparatus. The
description of the present invention is intended to be
illustrative, and not to limit the scope of the claims. Many
alternatives, modifications, and variations will be apparent to
those skilled in the art.
