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.

Claims
What is claimed is:
1. A parquet block with a woodwork joints having four sides; a
longitudinal notch having a short upper side and a long lower side
with a distal edge and defined at one of the sides near the upper
side edge of the parquet block; a longitudinal tongue having a
short upper side and a long lower side with a proximal edge and
defined on a side opposite to the longitudinal notch of the parquet
block to be inserted into the longitudinal notch in an adjacent
parquet block; two transverse tongues having a width and defined
respectively on the sides different from the longitudinal notch and
the longitudinal tongue; and two transverse grooves having a width
equal to the width of the transverse tongues and defined
respectively beside the transverse tongues so that a transverse
tongue on an adjacent parquet block can be mounted inside the
adjacent transverse groove.
2. The parquet block with the woodwork joint as claimed in claim 1,
wherein the longitudinal notch further comprises an upward
protrusion formed on the distal edge of the longitudinal notch, and
the longitudinal tongue further comprises a longitudinal detent
defined on the proximal edge of the long lower side of the
longitudinal tongue.
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 into the groove (10) on an adjacent
parquet block to form a joint. The conventional tongue and groove
joint positively holds abutting parquet blocks transversely
relative to each other. 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.
[0006] To overcome the shortcomings of the conventional woodwork
joint, the present invention provides a parquet block with woodwork
joints to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
adjacent parquet blocks with woodwork joints having opposite
parallel abutting edges, a longitudinal notch, a longitudinal
tongue, two transverse grooves and two transverse tongues, which
will not separate either longitudinally or transversely. The
longitudinal notch is defined at parallel abutting edges of one of
the parquet blocks. The tongue is formed on the parallel abutting
edge of the adjacent parquet block opposite to and inserted into
the notch in the adjacent parquet block. The groove is defined on
another edge adjacent to the edge with the notch, the tongue is
formed on the side opposite from the groove so the tongue can be
mounted in the groove of the adjacent parquet block.
[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.
[0009] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] With reference to FIGS. 1 to 4, a parquet block in
accordance with the present invention has woodwork joints to
connect firmly to adjacent parquet blocks in each direction. The
parquet block in accordance with the present invention has a front
side (not numbered), a rear side (not numbered), a right side (not
numbered), a left side (not numbered), an upper edge (not
numbered), a lower edge (not numbered), a longitudinal tongue (1),
a longitudinal notch (6), two transverse grooves (5) and two
transverse tongues (3).
[0018] With further reference to FIG. 3, the longitudinal tongue
(1) and the notch (6) are formed respectively on the right side and
left side of the parquet block opposite to each other. The
longitudinal tongue (1) has a short upper side (not numbered) and a
long lower side (not numbered). The long lower side has a proximal
edge (not numbered) and a longitudinal detent (2). The longitudinal
detent (2) is formed at the proximal edge of the long lower side of
the longitudinal tongue (1). The longitudinal notch (6) has a short
upper side (not numbered) and a long lower side (not numbered). The
long lower side has a distal edge (not numbered) and an upward
protrusion (7). The upward protrusion (7) is formed at the distal
edge of the long lower side of the longitudinal notch (6) and
corresponds to the longitudinal detent (2) in the longitudinal
tongue (1). The longitudinal tongue (1) is inserted longitudinally
into the longitudinal notch (6) in an adjacent parquet block, and
the upward protrusion (7) is securely held in the longitudinal
detent (2).
[0019] With reference to FIG. 4, the transverse tongues (3) and the
transverse grooves (5) are defined on sides of the parquet block
different from the sides with the longitudinal notch (6) and the
longitudinal tongue (1). The width of the transverse tongue (3) is
equal to the width of the transverse groove (5). The transverse
tongues (3) are integrally formed on the side and the transverse
grooves (5) are defined beside the transverse tongues (3).
[0020] With further reference to FIGS. 5 and 6, the parquet blocks
with the woodwork joints are assembled by first inserting a
transverse tongue (3) into an adjacent transverse groove (5) to
connect the parquet blocks together in one direction. The
longitudinal tongue (1) is transversely inserted into the
longitudinal notch (6) of another adjacent parquet block and the
upward protrusion (7) is mounted inside the longitudinal detent (2)
so that the parquet blocks connect firmly to the adjacent parquet
blocks in a longitudinal direction.
[0021] The parquet block with the woodwork joint in accordance with
the present has the following advantages.
[0022] 1. The parquet blocks are securely held in longitudinal and
transverse by the transverse tongues (3) inserted into the
transverse grooves (5), the longitudinal tongues (1) inserted into
the longitudinal notches (6) and the upward protrusions (7)
inserted into the longitudinal detents (2).
[0023] 2. The parquet block with the woodwork joint in accordance
with the present invention can prevent the joint from separating so
that the parquet blocks with the woodwork joint provide an
attractive appearance.
[0024] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, that the disclosure is illustrative only, and changes
may be made in detail, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
which the appended claims are expressed is to be understood.
