Sand bag structure
Abstract
A sand bag structure includes a main body including two sides
and a bottom integrally combined with each other. Thus, the two
sides and the bottom of the main body are integrally combined with
each other, and each of the two sides and the bottom of the main
body has a determined width and thickness so as to enhance the
support effect of the sand bag structure, thereby preventing the
sand bag structure from being broken when containing the sand.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a sand bag structure, and
more particularly to a sand bag structure, wherein the two sides
and the bottom of the main body are integrally combined with each
other, and each of the two sides and the bottom of the main body
has a determined width and thickness so as to enhance the support
effect of the sand bag structure, thereby preventing the sand bag
structure from being broken when containing the sand.
[0003] 2. Description of the Related Art
[0004] A conventional sand bag in accordance with the prior art
shown in FIG. 3 comprises a main body 10 for containing sand and
including two sides 12, a bottom 14 connected to the two sides 12.
In fabrication, the two sides 12 of the main body 10 are formed by
folding the main body 10, and the bottom 14 of the main body 10 is
formed by a stitching line 20.
[0005] However, the stitching line 20 is easily torn or broken due
to the weight of the sand, so that the sand falls out of the main
body 10. In addition, the two sides 12 of the main body 10 are
easily worn out during a long period of time, thereby decreasing
the lifetime of the conventional sand bag.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a sand bag structure, wherein the two sides and the bottom of the
main body are integrally combined with each other, and each of the
two sides and the bottom of the main body has a determined width
and thickness so as to enhance the support effect of the sand bag
structure, thereby preventing the sand bag structure from being
broken when containing the sand.
[0007] Another objective of the present invention is to provide a
sand bag structure, wherein the two sides and the bottom of the
main body are integrally combined with each other, and each of the
two sides and the bottom of the main body has a determined width
and thickness so as to enhance the strength of the sand bag
structure, thereby preventing increasing the lifetime of the sand
bag structure.
[0008] A further objective of the present invention is to provide a
sand bag structure, wherein each of the two sides and the bottom of
the main body has a determined width and thickness, thereby
facilitating the user taking and carrying the sand bag
structure.
[0009] In accordance with the present invention, there is provided
a sand bag structure, comprising a main body including two sides,
and a bottom connected to the two sides, wherein:
[0010] the two sides and the bottom of the main body are integrally
combined with each other;
[0011] each of the two sides of the main body has a determined
width and thickness; and
[0012] the bottom of the main body has a determined width and
thickness.
[0013] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] FIG. 1 is a perspective view of a sand bag structure in
accordance with the preferred embodiment of the present
invention;
[0015] FIG. 2 is a top plan view of the sand bag structure as shown
in FIG. 1; and
[0016] FIG. 3 is a perspective view of a conventional sand bag in
accordance with the prior art.
DETAILED DESCRIPTION OF THE INVENTION
[0017] Referring to FIGS. 1 and 2, a sand bag structure in
accordance with the preferred embodiment of the present invention
comprises a main body 30 including two sides 40, a bottom 60
connected to the two sides 40, a first layer 70 mounted between the
two sides 40 and the bottom 60, and a second layer 80 mounted
between the two sides 40 and the bottom 60 and separated from the
first layer 70.
[0018] Preferably, the two sides 40 and the bottom 60 of the main
body 30 are integrally formed by a knitting process. In addition,
each of the two sides 40 of the main body 30 has a strip shape and
has a determined width and thickness. In addition, the bottom 60 of
the main body 30 has a strip shape and has a determined width and
thickness. In addition, an opening 90 is formed between the first
layer 70 and the second layer 80 for containing sand therein.
[0019] Accordingly, the two sides 40 and the bottom 60 of the main
body 30 are integrally combined with each other, and each of the
two sides 40 and the bottom 60 of the main body 30 has a determined
width and thickness so as to enhance the support effect of the sand
bag structure, thereby preventing the sand bag structure from being
broken when containing the sand. In addition, the two sides 40 and
the bottom 60 of the main body 30 are integrally combined with each
other, and each of the two sides 40 and the bottom 60 of the main
body 30 has a determined width and thickness so as to enhance the
strength of the sand bag structure, thereby preventing increasing
the lifetime of the sand bag structure. Further, each of the two
sides 40 and the bottom 60 of the main body 30 has a determined
width and thickness, thereby facilitating the user taking and
carrying the sand bag structure.
[0020] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
