Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a design of paper pallet,
and more particularly to a high load-bearing paper pallet for
placing and carrying goods.
[0003] 2. Description of the Related Art
[0004] In goods warehousing, a pallet is usually used as a platform
for placing and carrying goods to facilitate goods management and
transportation. The pallet comprised of a plurality of board
carrying members forms a platform for placing and containing goods,
and the pallet is also comprised of a carrying member having a
plurality of legs disposed at the bottom of the platform. The legs
lift the platform to a certain height, so that a fork of a forklift
can be extended into the bottom of the platform from the space
lifted by the legs, so as to transport the whole paper pallet as
well as the goods.
[0005] Traditional pallets are made of wooden boards formed by
nailing the wooden boards together or integrally formed by plastic
materials. In general, the material cost, the level of difficulty
of the manufacture, and the environmental protection are taken into
consideration for determining the material used for making pallets,
particularly, the environmental protection factor. Since pallets
are shipped together with the goods to different ports all over the
world and wooden pallets have the risk of ruining our forests and
the issues of biological prevention, therefore manufacturers
developed a paper pallet and used the special properties of the
reusability and recyclability of the paper to make gulp of the
paper pallet which has gone through a high-temperature infection
procedure, so that the paper pallets can further meet the
requirements of economics and environment protection.
[0006] Referring to FIG. 1 for the schematic view of a structure of
a prior art paper pallet, a platform disposed on the paper pallet
for carrying goods comprises a plurality of rectangular sheet
carrying members 10, and the structure of the carrying member 10
includes a plurality of longitudinally and transversally interlaced
corrugated paper boards A in the surface paper material B, such
that when the carrying member 10 carries the goods C, the carrying
member 10 will not be collapsed or deformed due to the heavy weight
of the goods C.
[0007] Since the carrying member 10 of the prior art paper pallet
only emphasizes on the structural strength for bearing a vertical
compressing force, therefore if the weight of the goods C does not
apply a force on the carrying member 10 evenly, the weight of the
goods C and the supporting force of the fork D will create a
certain shear stress onto the carrying member 10, and thus the
carrying member 10 may be bent or deformed, or even more seriously
the carrying member 10 may be cracked or broken.
SUMMARY OF THE INVENTION
[0008] In view of the description above, the inventor of the
present invention based on years of experience of the related
industry to conduct extensive experiments and tests in hope of
overcoming the foregoing shortcomings of the prior art
[0009] Therefore, the primary objective of the present invention is
to provide a high load-bearing paper pallet that comprises a
plurality of sheet carrying members, and a plurality of legs
installed under the carrying members, wherein the carrying members
are arranged to form a platform for carrying goods, such that a
fork of a forklift can be extended into the bottom of the platform
from the space lifted by the legs for carrying the whole paper
pallet and the goods, characterized in that the carrying members or
legs are made of engaging a plurality of circular paper rolls with
each other and using a surface paper material to wrap the carrying
members and legs, such that the mutually engaged circular paper
rolls can increase the resistance to the shear stress produced
between the goods and the fork to prevent the carrying member from
being broken or deformed.
[0010] The secondary objective of the present invention is to
provide circular paper rolls mainly made of a waste material of a
paper roll produced in the process of manufacturing a chemical
fiber rolls or fabrics, such that the waste material can be reused,
and the manufacture of the paper pallet further meets the
requirements of the environmental protection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] To make it easier for our examiner to understand the
objective of the invention, its structure, innovative features, and
performance, we use a preferred embodiment together with the
attached drawings for the detailed description of the
invention.
[0028] Referring to FIG. 2 for the structure and application of the
whole paper pallet of a high load-bearing paper pallet in
accordance with the present invention, the paper pallet comprises a
plurality of neatly arranged carrying members 10 disposed on the
platform, and a plurality of legs 20 installed under the carrying
members 10, and the carrying members 10 and the legs 20 are engaged
with each other by a plurality of circular paper rolls, and their
exterior is wrapped by a surface paper material.
[0029] Referring to FIGS. 3 and 4, the carrying member 10 of this
preferred embodiment uses a plurality of first circular paper rolls
11 to engage with each other, and then uses a surface paper
material B to wrap their exterior. The first circular paper rolls
11 include a plurality of grooves 12 disposed on a side wall of the
first circular paper roll 11, and two adjacent first circular paper
rolls 11 are engaged with each other in opposite directions, such
that the groove bottoms 13 of the mutually engaged grooves 12 are
stacked with each other for improving the load carrying capability
between two adjacent first circular paper rolls 11, and the
plurality of interlaced first circular paper rolls 11 in opposite
directions can be engaged with each other to form a rectangular
bar, and finally a surface paper material B is used for wrapping
their exterior to form the carrying member 10.
[0030] Referring to FIGS. 5 to 9 for the implementation of the legs
20 according to the preferred embodiments of the present invention,
a plurality of second circular paper rolls 21 are engaged with each
other, and then a surface paper material B is used for wrapping the
exterior of the second circular paper rolls 21. For the
implementation of the second circular paper rolls 21, the side wall
of each second circular paper roll 21 includes at least one channel
22, such that two adjacent second circular paper rolls 21 can pass
into the channel 22 through the sidewall, and two adjacent second
circular paper rolls 21 are interlaced and coupled into a
rectangular bar, and a surface paper material B is also used for
wrapping the exterior of the second circular paper rolls 21 to form
the legs 20.
[0031] Referring to FIG. 2, the height of the legs 20 can lift the
carrying member 10 to an appropriate height to form the paper
pallet, so that a fork of a forklift D can be extended into the
bottom of the carrying member 10 from the space lifted by the legs
20 to facilitate the transportation of the whole paper pallet and
the goods C. If the goods C are placed on the carrying member 10
and the fork of a forklift D can be used to lift the goods C for
transportation, the plurality of the first circular paper rolls 11
of the carrying members 10 are engaged with each other, and thus
improving the structural strength to prevent the carrying member 10
from being broken or deformed as well as improving the load bearing
of the overall paper pallet.
[0032] It is worthy to point out that the first circular paper
rolls 11 and the second circular paper rolls 21 of the present
invention can be made by a waste material of the paper rolls by
using a secondary manufacturing process, and thus the manufacture
of the paper pallet not only complies with the requirements of the
environmental protection, but also can allows manufacturers to cut
the first circular paper rolls 11 and the second circular paper
rolls 21 according to actual needs, and further change the height
of the carrying members 10 and the legs 20.
[0033] Referring to FIGS. 7 and 9, two adjacent second circular
paper rolls 21 are engaged with each other by the channels 22
disposed on the sidewall of the second circular paper rolls 21, and
thus two adjacent second circular paper rolls 21 engaged by using
the channels 22 can be slid along the channel 22 on the sidewalls
to adjust the distance between two adjacent second circular paper
rolls 21 and further increase or decrease the number of second
circular paper rolls 21 according to the actual needs.
[0034] Referring to FIGS. 10 and 11, the first circular paper rolls
11 and the second circular paper rolls 22 are stacked with each
other, and a surface paper material is used for wrapping them, so
as to increase the height and structural strength of the carrying
members 10 and the legs 20.
[0035] Referring to FIGS. 12 to 15, the legs 20 are made of a
circular paper roll of a different height, which is referred to as
third circular paper rolls 30 here. The third circular paper rolls
30 include a plurality of grooves 31 mutually embedded with each
other by using the third circular paper rolls 30 of different
heights. The embedment is accomplished by alternately arranging the
paper rolls as shown in the figures.
[0036] Referring to FIGS. 14 and 15, the external diameter of the
third circular paper rolls 30 is slightly smaller than the internal
diameter of the first circular paper rolls 11, so that the first
circular paper rolls 11 can be sheathed into the taller third
circular paper rolls 30. Finally, a surface paper material B is
used to wrap the third paper rolls 30 to form a plurality of legs
20 with different heights. The carrying board 10 made of the first
circular paper rolls 11 can be placed on top of the legs 20 made of
the third circular paper rolls 30, and then the first circular
paper rolls 11 and the third circular paper rolls 30 constitute a
high load-bearing paper pallet.
[0037] Referring to FIG. 16, the carrying members 10 made of the
first circular paper rolls 11 are placed on the legs 20 made of the
third circular paper rolls 30. Since the legs 20 are made of the
third circular paper rolls 30 of different heights by placing the
third circular paper rolls on concentric circles, therefore the
first circular paper rolls 11 can be sheathed into the third
circular paper rolls 30 and the bottom of the first circular paper
rolls 11 is attached precisely onto the third circular paper rolls
30 having a smaller height, and thus the shorter third circular
paper rolls 30 can support the first circular paper rolls 11, and
the first circular paper rolls 11 can be fixed onto the third
circular paper rolls 30 to constitute a high load-bearing paper
pallet structure.
[0038] While the invention has been described by way of example and
in terms of a preferred embodiment, it is to be understood that the
invention is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements and
procedures, and the scope of the appended claims therefore should
be accorded the broadest interpretation so as to encompass all such
modifications and similar arrangements and procedures.
[0039] In summation of the above description, the present invention
herein enhances the performance than the conventional structure and
further complies with the patent application requirements and is
submitted to the Patent and Trademark Office for review and
granting of the commensurate patent rights.
