Description

Self-locking floor technology

The present invention relates to a floor, and more particularly to a floor with a separate locking device.

Background technique

Nowadays, in the field of interior floor decoration, the use of hard floors has become more common, such as solid wood flooring, composite wood flooring and so on. There are a variety of installation methods for such a floor. The first method is to first lay a floor connection bracket on the ground, and then fix the floor to the floor connection bracket with an adhesive or rivet. The disadvantage of this installation method is quite complicated. And it can only be dismantled by damaging the floorboard.

The second way is to machine the periphery of the floorboard out of the tongue and groove structure, and then loosely lay the floorboard on the bottom surface. The floorboards are combined with each other by the cooperation relationship between the floor and the groove, and usually the adhesive is also used. Bond them together on the groove and groove. The advantage of this type of installation is that the installation is convenient, and the floor blocks can be relatively moved between each other, which is advantageous for adapting to dimensional changes caused by thermal expansion and contraction of the floor plates. However, the disadvantage is that the floor piece undergoes dimensional changes during thermal expansion and contraction, which causes separation between the floor blocks, breaks the connection of the adhesive, and causes a large gap between the floor blocks, which affects the appearance.

In order to improve the above-mentioned defects in the installation of the floor, the UNILIN company in the Netherlands published a patent application file (W09747834) for a hard floorboard in 1997, the technical solution of which is mainly to work in the edge of the opposite side of the floor. The connecting portion is generally constituted by a tongue and a groove, and the tongue and the groove constitute a combined mechanical locking device. The locking device prevents the two mating floor blocks from being separated in the horizontal direction, thereby overcoming the floor block. Defects that create gaps during thermal expansion and contraction reduce the possibility of dust and moisture ingress. The patent application discloses several specific embodiments, but each of the embodiments has certain problems, and the main points are summarized as follows: 1. Refer to the drawings of the patent application documents, FIG. 2 to FIG. 4 and FIG. The tongue 9 can only be inserted into or removed from the slot 10 at an angle, but this embodiment cannot be used when it is only installed in a horizontal position at some special positions, and is suitable for processing. The groove 10 must inevitably cause a certain loss to the panel area of the floorboard; 2. Referring to Figures 5 to 10 of the specification of the patent application, the tongue 31 can only be inserted into the groove 32 in the horizontal direction, and the tongue is not easily The object 31 is pulled out of the groove 32. Therefore, although the technical solution disclosed in the patent application file solves the defects existing in the previous method of installing the floorboard, its practicability is also affected due to the limitations of its own structure.
