FLOOR PLANK WITH ADHESIVE PORTION ABLE TO ADJUST THE POSITION
The present invention relates to a double-layered floor plank sheet having a non-adhesive portion, more particularly to a floor plank sheet enabling adjustment of position during installation. When the upper layer of a floor plank sheet is bonded to the lower layer of another floor plank sheet, a non-adhesive portion formed in part of an adhesive portion enables the adjustment of position.
This application claims all benefits of Korean Patent Application No. 20-2007-0015010 filed on Sep. 7, 2007 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a floor plank sheet, more particularly to a floor plank sheet enabling adjustment of position during installation. When the upper layer of a floor plank sheet is bonded to the lower layer of another floor plank sheet, a non-adhesive portion formed in part of an adhesive portion enables an operator to adjust the position of the floor plank sheet.
2. Description of the Prior Art
The floor plank refers to a material bonded on a floor and having a surface to be worn down. In general, thin board- or laminated paper-type sheets are used indoors, rather than tiles or ceramics.
The conventional laminated paper-type sheets are made with a predetermined width and extendable in the length direction, and are cut according to the area of the corresponding floor. In case the floor shape does not coincide with the width of the laminated paper, the remaining portion of the laminated paper is cut off, or the insufficient portion is compensated by overlapping the laminated paper.
Recently, blocks of regular size are used for flooring. In general, after applying adhesives on the floor surface, the block-type floor planks are bonded thereon.
SUMMARY OF THE INVENTIONAn object of the present invention is to enable the adjustment of position of floor planks during installation.
Another object of the present invention is to prevent the edge of the floor plank from directly contacting the pre-applied adhesive, so that the adhesive may not be pushed to away, lumped at the portion overlapped with the neighboring plank, or exposed out of the upper layer of the floor plank.

The above and other features of the present invention will now be described in detail with reference to certain exemplary embodiments thereof illustrated by the accompanying drawings which are given hereinbelow by way of illustration only, and thus are not limitative of the present invention, and wherein:
It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features of the present invention. The specific design features of the present invention as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes thereof will be determined in part by the particular intended application and use environment.
DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTSReference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the drawings attached hereinafter, wherein like numerals refer to like elements throughout. The embodiments are described below so as to explain the present invention by referring to the figures.
The adhesive portion (11, 21) formed on the upper layer (10) and the lower layer (20) is extended in L-form when the upper layer (10) and the lower layer (20) of the floor plank (1) are rectangles. Preferably, the upper layer (10) is laminated on the lower layer (20), so that the sides that form the L-form are extended by the same length to each direction.
As illustrated in
Specifically, the non-adhesive portion may be formed on the adhesive portion (11) in one or more areas. As seen in
In the mean while, when the upper layer (10) of the floor plank (1) is made of wood, bonding to the floor and neighboring floor planks (1) become easier.
Although a non-adhesive material (13, 23) was exemplified for the non-adhesive portion in
Particularly, the purpose may be attained by not applying the adhesive (30) in some part of the lower surface of the upper layer (10) and the upper surface of the lower layer (20) of the floor plank (1). The portion on which the adhesive (30) is not applied may be formed continuously or intermittently along the length direction of the adhesive portion (11, 21).
Since the end of the adhesive portion (11) of the upper layer (10) directly contacts the adhesive portion (21) of the lower layer (20) of the floor plank (1) to be installed, the C-trimming (14) of the end of the lower surface of the adhesive portion (11), as illustrated in
Such disposition of the non-adhesive portion only one side of the adhesive portion (11, 21) of the floor plank (1) rather all of the adhesive portion (11, 21) of the floor plank (1) may be employed even when the floor plank (1) is in square form.
The floor plank according to the present invention enables the adjustment of adjustment of position during installation. Further, it prevents the problem of the adhesive being pushed away from the edge of the floor plank, thereby providing even connection of the floor planks.
The invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
