Parquet block with woodwork joints

Abstract

A parquet block with a woodwork joint has two parallel abutting sides, a longitudinal notch, a longitudinal tongue, two transverse grooves and two transverse tongues. The longitudinal notch, the longitudinal tongue, the transverse grooves and the transverse tongues on adjacent parquet blocks interlock to hold the parquet blocks securely in the longitudinal and transverse directions.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a parquet block with woodwork joints, especially to a parquet block with woodwork joints that can securely attach to adjacent parquet blocks and have an attractive appearance. [0003] 2. Description of Related Art [0004] People often use parquet floors to decorate houses. The parquet floors comprise parquet blocks connected to adjacent parquet blocks at a joint. However, the parquet blocks easily separate at the joint. [0005] With reference to FIG. 7, conventional parquet blocks use tongue and groove joints to overcome the foregoing problem. Adjacent parquet blocks have parallel abutting edges (not numbered), grooves (10) and tongues (9). A groove (10) is defined on one of the abutting edges, and a tongue (9) is formed on the abutting edge opposite to the groove (10). When the tongue (9) and the groove (10) are joined, the tongue (9) on an abutting side of a parquet block is inserted ...

AI Technical Summary

Benefits of technology

[0008] Assembling the parquet blocks with the foregoing woodwork joint features makes the parquet blocks connect firmly and keeps the parquet blocks from releasing in either the transverse or longitudinal direction.

Problems solved by technology

However, the groove (10) and the tongue (9) of the conventional woodwork joint cannot positively hold abutting parquet longitudinally relative to each other so the joint between abutting parquet blocks easily separates in a longitudinal direction.

When the parquet blocks separate enough in the longitudinal direction, the parquet blocks will lift from the floor and have an unattractive appearance.
