[37] 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.
[38]
Best Mode for Carrying Out the Invention
[39] Reference 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. Fig. 1 is a perspective view schematically illustrating the assembly of the floor plank (1) according to an embodiment of the present invention. As illustrated in the figure, the side of a floor plank (1) adjoins the side of another floor plank (1). Preferably, as shown in the figure, the position of the floor plank (1) to be fixed is adjusted by slanting the floor plank (1). Figs. 2 and 3 are perspective view and side assembly view schematically illustrating the floor plank (1) according to an embodiment of the present invention, respectively. As illustrated in Figs. 2 and 3, the floor plank (1) of the present invention has a double-layer structure of an upper layer (10) and a lower layer (20), the upper layer (10) being laminated on the lower layer (20), so that the upper layer (10) and the lower layer (20) are arranged to be terrace shaped. At the portion where the lower surface of the upper layer (10) and the upper surface of the lower layer (20) are not overlapped each other, that is at the adhesive portions (11, 21), an adhesive (30) is applied in advance. As illustrated in the figure, the adhesive portion (21) of the lower layer (20) of one floor plank (1) is placed and fixed on the adhesive portion (11) of the upper layer (10) of the neighboring floor plank (1). A non- adhesive portion is formed in part of the adhesive portion (21).
[40] 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.
[41] As illustrated in Fig. 3, the adhesive (30) is pre-applied on the lower surface of the upper layer (10) and the upper surface of the lower layer (20), so that the upper layer
(10) and the lower layer (20) may be bonded. The adhesive portion (11) of the upper layer (10) of the floor plank (1) to be installed is placed on the adhesive portion (21) of the lower layer (20) of the floor plank (1) which was installed earlier. The floor plank (1) to be installed is slanted, so that the side surface of the upper layer (10) of the floor plank (1) to be installed may contact the side surface of the upper layer (10) of the floor plank (1) which was installed earlier. The non-adhesive portion formed on in part of the adhesive portion (21) of the lower layer (20) enables adjustment of position during installation. That is, the non-adhesive portion prevents the adhesive portion (11) of the upper layer (10) of the floor plank (1) to be installed from being bonded and fixed to the adhesive portion (21) of the lower layer (20) of the floor plank (1) which was installed earlier, and enables the adjustment of the position at which the edge portion of the adhesive portion (11) of the upper layer (10) and the side surface of the upper layer (10) contacts the lower layer (20) of the floor plank (1) which was installed earlier, thereby enabling the installation of the floor plank (1) at right position.
[42] Specifically, the non-adhesive portion may be formed on the adhesive portion (21) in one or more areas. As seen in Fig. 2, it may be formed continuously along one direction, or intermittently. Even when the non-adhesive portion is formed intermittently, it may perfectly prevent the adhesive portions (11, 21) of the neighboring floor planks (1) being from bonded to each other and, thus, enables the adjustment of installation position. Preferably, as illustrated in Figs. 1 to 3, the non-adhesive portion formed on the adhesive portion (21) of the lower layer (20) of the floor plank (1) is formed at the portion where the edge portion of the adhesive portion (11) of the upper layer (10) and the side surface of the upper layer (10) of the floor plank (1) to be installed contacts directly, that is at the portion where the upper layer (10) and the lower layer (20) of the floor plank (1) which was installed earlier meet each other.
[43] In the figure, the non-adhesive portion is described as a groove (22). The groove
(22) is formed before applying the adhesive (30). Since the groove (22) is with no adhesive (30) or only little, if any, it can prevent the adhesive portion (11) of the upper layer (10) of the floor plank (1) to be installed from being bonded completely by a single contact to the adhesive portion (21) of the lower layer (20) of the floor plank (1) which was installed earlier. The non-adhesive portion, that is the groove (22), is formed only in part of the adhesive portion (21) of the lower layer (20), and does not affect the overall adhesion to the neighboring floor plank (1). Also, since the groove (22) is almost without the adhesive (30), the adhesive (30) applied on the adhesive portion (21) of the lower layer (20) of the floor plank (1) which was installed earlier is not pushed away by the edge portion of the side surface and the lower surface of the upper layer (10) of the neighboring floor plank (1). Accordingly, the contact surface of the two floor planks (1) is maintained clean.
[44] The non-adhesive portion may be formed on the upper layer (10) of the floor plank
(1), as well as on the lower layer (20). The presence of the non-adhesive portion on either of the upper layer (10) or the lower layer (20) sufficiently prevents the two neighboring floor planks (1) from being bonded to each other upon initial contact. However, when the non-adhesive portion is formed on the adhesive portions (11, 21) of both the upper layer (10) and the lower layer (20), the adjustment of the installation position of the floor plank (1) becomes easier.
[45] Particularly, 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.
[46] Although a groove (22) was exemplified for the non-adhesive portion in Figs. 1 to
3, the non- adhesive portion may be formed in various forms, as long as it may prevent the floor planks (1) from being bonded completely by the adhesive (30) upon initial contact. 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).
[47] Figs. 4 to 6 are perspective view, side assembly view and bottom perspective view schematically illustrating the floor plank (1) according to another embodiment of the present invention, wherein a non-adhesive material (13, 23) is attached on the adhesive portion (11, 21), respectively. The non-adhesive material (13, 23) is attached on the upper surface of the adhesive portion (21) after the application of the adhesive (30). The non-adhesive material (13, 23) may be paper, fabric, specially processed sheet, etc. and, preferably has a small thickness, so that the height is not quite different from that of the adhesive portion. Fig. 6 is a bottom perspective view schematically illustrating the floor plank (1) wherein a non-adhesive material (13) on the adhesive portion (11) of the lower surface of the upper layer (10).
[48] The non-adhesive material (13, 23) is attached on the upper surface of the adhesive portion (11, 21), thereby covering the adhesive (30) and preventing the adhesive portions (11, 21) of the two floor planks (1) being bonded completely.
[49] Figs. 7 and 8 are bottom perspective view and side assembly view schematically illustrating the floor plank (1) according to still another embodiment of the present invention, wherein the edge portion of the adhesive portion (11) of the upper layer (10) and the side surface of upper layer (10) is trimmed in the shape of C (14), respectively. 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 Fig. 8, prevents the adhesive (30) on the adhesive portion (21) of the lower
layer (20) from being pushed away during the adjustment of the installation position of the floor plank (1). Also in the embodiments illustrated in Figs. 2 and 5, when the upper layer (10) of the floor plank (1) to be installed is placed on the lower layer (20) of the floor plank (1) which was installed earlier, the non-adhesive portion prevents the edge portion of the side surface and the lower surface of the upper layer (10) of the neighboring floor plank (1) from directly contacting the adhesive (30) applied on the adhesive portion (21), thereby preventing the floor plank (1) fixed wrongly upon initial contact and preventing the formation of crevices between the neighboring floor planks (1), which may be caused by the pushing away of the adhesive (30).
[50] Figs. 9 and 10 are perspective views schematically illustrating the floor plank (Ia) with a different shape according to yet another embodiment of the present invention. In such a long rectangular floor plank (Ia), the non-adhesive portion may be formed along both the length direction and the vertical direction, as shown in the figure. Alternatively, the non-adhesive portion may be formed only along the length direction.
[51] 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.
[52]
Industrial Applicability
[53] 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.
