Floor plank with adhesive portion able to adjust the position

Abstract

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.

1 . A double-layered floor plank ( 1 ) having an non-adhesive portion, the floor plank ( 1 ) comprising a lower layer ( 20 ) contacting the floor, and an upper layer ( 10 ) laminated on the lower layer ( 20 ),
 adhesive portions ( 11 ,  21 ) being formed on the lower surface of the upper layer ( 10 ) and the upper surface of the lower layer ( 20 ), respectively, by applying an adhesive ( 30 ),   the upper layer ( 10 ) being laminated on the upper surface of the lower layer ( 20 ), so that the lower surface of the upper layer ( 10 ) and the upper surface of the lower layer ( 20 ) have a height difference, and   a non-adhesive portion without being exposed to the adhesive ( 30 ) being formed in part of the adhesive portion ( 11 ) of the upper layer ( 10 ).   
   
   
       2 . The floor plank having an adhesive portion according to  claim 1 , wherein the non-adhesive portion is formed only along one direction on the adhesive portion ( 11 ) of the upper layer ( 10 ) of the floor plank ( 1 ). 
   
   
       3 . The floor plank having an adhesive portion according to  claim 1 , wherein the non-adhesive portion is formed along the length direction of the adhesive portion ( 11 ) of the upper layer ( 10 ), by not applying the adhesive ( 30 ). 
   
   
       4 . The floor plank having an adhesive portion according to  claim 3 , wherein the non-adhesive portion is formed intermittently along the length direction of the adhesive portion ( 21 ). 
   
   
       5 . The floor plank having an adhesive portion according to  claim 1 , wherein the edge portion where the adhesive portion ( 11 ) of the lower surface of the upper layer ( 10 ) contacts the side surface of the upper layer ( 10 ) is trimmed in the shape of C ( 14 ). 
   
   
       6 . The floor plank having an adhesive portion according to  claim 5 , wherein the C-trimming ( 14 ) is formed intermittently on the edge portion where the adhesive portion ( 11 ) of the lower surface of the upper layer ( 10 ) contacts the side surface of the upper layer ( 10 ). 
   
   
       7 . The floor plank having an adhesive portion according to  claim 1 , wherein the non-adhesive portion is formed on the adhesive portion ( 11 ) of the upper layer ( 10 ) by attaching a non-adhesive material ( 13 ). 
   
   
       8 . The floor plank having an adhesive portion according to  claim 7 , wherein the non-adhesive material ( 13 ) is paper, fabric or special sheet. 
   
   
       9 . The floor plank having an adhesive portion according to  claim 1 , wherein the upper layer ( 10 ) of the floor plank ( 1 ) is made of wood. 
   
   
       10 . The floor plank having an adhesive portion according to  claim 1 , wherein a non-adhesive portion without being exposed to the adhesive ( 30 ) being formed in part of the adhesive portion ( 21 ) of the lower layer ( 20 ). 
   
   
       11 . The floor plank having an adhesive portion according to  claim 10 , wherein the non-adhesive portion is formed only along one direction on the adhesive portion ( 21 ) of the lower layer ( 20 ) of the floor plank ( 1 ). 
   
   
       12 . The floor plank having an adhesive portion according to  claim 10 , wherein the non-adhesive portion is formed along the length direction of the adhesive portion ( 21 ) of the lower layer ( 20 ), by not applying the adhesive ( 30 ). 
   
   
       13 . The floor plank having an adhesive portion according to  claim 12 , wherein the non-adhesive portion is formed intermittently along the length direction of the adhesive portion ( 21 ). 
   
   
       14 . The floor plank having an adhesive portion according to  claim 10 , wherein the non-adhesive portion is formed along the length direction of the adhesive portion ( 21 ) of the lower layer ( 20 ) as a groove ( 22 ). 
   
   
       15 . The floor plank having an adhesive portion according to  claim 14 , wherein the groove ( 22 ) formed intermittently along the length direction of the adhesive portion ( 21 ). 
   
   
       16 . The floor plank having an adhesive portion according to  claim 10 , wherein the non-adhesive portion is formed on the adhesive portion ( 21 ) of the lower layer ( 20 ) by attaching a non-adhesive material ( 23 ). 
   
   
       17 . The floor plank having an adhesive portion according to  claim 16 , wherein the non-adhesive material ( 23 ) is paper, fabric or special sheet.
