Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to an interlocking type plastic tile structure, especially to an interlocking type plastic tile structure which is simple in assembling and precise in insertion and alignment by the formation of protruding tongues and notches capable of interlocking.
  • 2. Brief Description of the Prior Art
  • The adhering structure of ordinary plastic tile, as shown in FIG. 5, substantially has printed layer between a main body (51) and a transparent leather (54), and the printed layer further includes a PVC leather material (52) and a printed pattern layer (53). The main body (51) is essentially formed by the mixing of PVC powder, calcium carbonate and toughening agent (DOP). The printed pattern layer (53) can be printed either on the bottom face of the transparent leather (54) or on the surface of the PVC leather material (52). Hot pressing is conducted on the main body (51), the PVC leather material (52), and the transparent leather (54) so that they are integrated and combined together to form plastic tile. The plastic tile thus formed is a piece of square or rectangular body which is then adhered on the floor piece by piece. However, the plastic tiles are apt to become oblique during adhesion by this method.
  • In view of the above defect, the structure disclosed in U.S. Pat. No. 7,155,871 B1 is proposed, as shown in FIGS. 6 and 7, in which a surface layer (6) and a base layer (61) to be adhered on the floor are essentially provided. The surface layer (6) and the base layer (61) are combined in staggered state such that the protruding portions (60), (62) are formed on two adjacent sides of the surface layer (6) and the base layer (61). An adhesive layer (63) is provided on the upper end surface of the protruding portion (62) of the base layer (61) and a release paper (64) is provided on the adhesive layer (63).
  • When plastic tiles are adhered in construction site, the base layer (61) of a plastic tile is adhered to the floor first, and then the release paper (64) is peeled apart from the adhesive layer (63) of the protruding portion (62) of the base layer (61). Thereafter, the protruding portion (60) of the surface layer (6) of another plastic tile is adhered with respect to the adhesive layer (63) of the protruding portion (62) of the base layer (61). In this manner, the plastic tiles can be adhered in order till finish.
  • However, this method has following shortcomings:
  • 1. The protruding portions of the surface layer and the base layer are bigger in areas; this will cause bigger allowance of adhering two plastic tiles together so that there is bad alignment on plastic tiles. Eventually, the entire floor is not beautiful.
  • 2. Release paper for protection purpose has to be provided on the protruding portion of the base layer having bigger area when manufacturing the plastic tile. Thus, manufacturing cost is high in this case.
  • In view of the above shortcomings, inventor of this invention proposes an interlocking type plastic tile structure according to the research and improvement conducted on conventional structure and its defects, based on profound experience in R&D and manufacturing in relevant field, with a purpose to achieve better performance value in practical application.
    • SUMMARY OF THE INVENTION

  • Essentially, the surface layer having pattern provided thereon is coated with adhesive and is combined with the PVC base layer in contact with floor, a plurality of protruding tongues and a plurality of notches being respectively formed on two adjacent sides of the PVC base layer. With this structure, when two such plastic tiles are interlocked with respect to each other, the notches having adhesive thereon are interlocked and adhered with the corresponding protruding tongues so as to finish assembly process and to achieve good alignment. Besides, there is no need to provide release paper, therefore cost can be saved and assembling can become very easy.
  • Moreover, the protruding tongues and the notches of the interlocking type plastic tile of the present invention are formed as dovetail shape. Alignment effect can be achieved in more stable manner by the mutual insertion and interlocking of the dovetail protruding tongues and the dovetail notches.
  • The upper surface of the interlocking type plastic tile structure of the present invention is combined with pattern which can be formed as stone material leather (marble leather), wood material leather (log leather), ceramic tile, cured resin coating, printed plastic baseboard, pure plastic tile, rubber tile, bamboo straw mat, wood tile, stone material tile etc., so as to enhance the aesthetic feeling and the selectivity of the plastic tile.
  • The upper surface of the interlocking type plastic tile structure of the present invention can be provided with a transparent protective layer so as to protect the surface layer.
