Sectional flooring

Abstract

Sectional flooring includes a first flooring unit and a second flooring unit assembled together using connecting structures that are different along long sides and short sides. With respect to the long sides, the first flooring unit includes a first indentation, a catch extension extending away from the first indentation and in a short side direction of the first flooring unit, and a connecting protrusion extending from a distal end of the catch extension. The second flooring unit includes a protuberance that is inserted into the first indentation, a second indentation formed extending further into the second flooring unit starting from the protuberance and for receiving the catch extension of the first flooring unit, and a third indentation formed extending into the second flooring unit from a side surface of the second indentation and into which the connecting protrusion is positioned.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to sectional flooring, and more particularly, to sectional flooring that allows for an increased interconnection strength and easy assembly between the different flooring units, and that is minimally deformed due to external factors such as moisture. [0003] (b) Description of the Related Art [0004] Sectional flooring is made of individual flooring units of predetermined dimensions. The individual flooring units are assembled on the floor of a building, home, apartment, etc. The individual flooring units are typically quadrilateral (i.e., rectangular), and have a specific connection structure along sides thereof to allow for interconnection with other flooring units. [0005] In more detail, protrusions and grooves are formed along at least one pair of opposing sides, and the individual flooring units are interconnected by inserting the protrusions of one unit into the grooves of another ...

AI Technical Summary

Benefits of technology

[0010] In one exemplary embodiment of the present invention, there is provided sectional flooring in which locking members are formed taking into consideration long side and short side characteristics of individual flooring units such that the interconnection strength between the flooring units is increased and assembly is made simple, and in which deformation caused by external factors such as moisture is minimized.

Problems solved by technology

However, a drawback of such a method is that removal of the flooring is difficult.

Also, if an adhesive is used, it is typically an epoxy-based material which is harmful to humans.

However, if the adhesive used for such a method is applied after it has been frozen or stored for long periods, its adhesivity decreases.

Also, gaps may form between the flooring units and surface uniformity may not be adequate if the adhesive is not properly applied.

However, a drawback of the configurations disclosed in these patents is that the interconnection strength between the flooring units is reduced considerably if there are defects in the floor of the structure or if a force is given to the flooring in one direction.

As a result, large gaps are formed or surface uniformity differences occur between the flooring units.
