Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to an improved fastening
strap structure including a strap body made of plastic material by
molding and at least one flexible metal reinforcing string
integrally embedded in the strap body. The reinforcing string
extends in a direction identical to the extending direction of the
strap body. The metal reinforcing string enhances tension strength
and shear strength of the fastening strap so that the fastening
strap can be used to tie large-size or heavyweight articles with
greater fastening force and the safety in use of the fastening
strap can be ensured.
[0002] A fastening strap is used to tie articles for easy transfer.
An automatic or semiautomatic tier is used to apply the fastening
strap to the articles. A domestically used fastening strap is used
to tie small-size lightweight articles. Therefore, the safety in
use of such fastening strap is not highly required. However, when
tying large-size and heavyweight articles, such fastening strap
will be unable to bear the load of the articles and it is necessary
to use fiber rope to tie the articles. This is quite
inconvenient.
[0003] Various kinds of improved fastening straps have been
developed for solving the above problem. Various kinds of fibers
are added to the fastening straps to enhance the tension strength
and shear strength thereof. However, such fastening straps still
have insufficient structural strength and can be hardly used to tie
up heavyweight articles.
SUMMARY OF THE INVENTION
[0004] It is therefore a primary object of the present invention to
provide an improved fastening strap structure including a strap
body made of plastic material by molding and at least one flexible
metal reinforcing string integrally embedded in the strap body. The
metal reinforcing string enhances tension strength and shear
strength of the fastening strap so that the fastening strap is not
likely to be torn apart by great tension or shearing force.
Therefore, the safety in use of the fastening strap can be
ensured.
[0005] The present invention can be best understood through the
following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Please refer to FIGS. 1 to 9. The fastening strap structure
of the present invention includes a strap body 20 made of plastic
material by molding and at least one metal reinforcing string 10
integrally embedded in the strap body 20. The reinforcing string 10
extends in a direction identical to the extending direction of the
strap body 20. The face of at least one side of the strap body 20
is formed with a series of stop teeth 21 which can be trapezoid
teeth, V-shaped teeth, bevel teeth, straight teeth or other teeth
with different patterns. The cross-section of the strap body 20 can
be flat (as shown in FIGS. 1 and 3), elliptic (as shown in FIGS. 7
and 8, circular (as shown in FIGS. 5 and 6), square (as shown in
FIG. 4) or polygonal (as shown in FIG. 9). The metal reinforcing
string 10 is embedded in the strap body 20 so that the strength of
the strap body is greatly enhanced.
[0018] In the case that the metal reinforcing string 10 is a
multi-strand cable, in comparison with the conventional fiber
string, the metal reinforcing string 10 has flexibility not less
than that of the fiber string. In addition, the metal reinforcing
string 10 has tension strength and shear strength much greater than
those of the fiber string. Therefore, the strength of the fastening
strap is apparently enhanced. When using the fastening strap to tie
a large-size and heavyweight article, the safety is ensured. In
addition, the stop teeth 21 formed on outer face of the strap body
20 enable the fastening strap to automatically fasten the article.
Therefore, the fastening strap can be conveniently used.
[0019] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. Many
modifications of the above embodiments can be made without
departing from the spirit of the present invention.
