A paper Pallet (100) comprises the top that some elongated units (200) form described pallet (100), and some beams (300) form bottom, support described top.By convention, for pallet, described top is called platform (501), and therefore described elongated units (200) is called top platform (502), and the bottom that described beam (300) is formed is called longeron (503).Described bottom also may be formed by back-up block (504).Fig. 1 a and 1b is depicted as a common wooden pallets (500), the unit of the described paper Pallet (100) wherein in the present invention imitates unit in described wooden pallet (500), while solving described wooden pallet (500) deficiency, ensure that good structure integrity.

Described some beams (300) support described some elongated units (200), need the object being undertaken transporting by vehicles such as such as fork trucks to be then placed in elongated units (200).

As shown in Figure 2 a, be a preferred embodiment of the present invention.In this preferred embodiment, described pallet (100) is two-way insert type, and two jaws of fork truck can only insert from described pallet (100) direction as shown in Figure 2 a or detach a pallet.Described elongated units (200) and beam (300) optimal case of described pallet (100) adopt some L-type unit (20a-f) and some support units (30a-c, 40) to form.

As shown in Figure 2 a, an elongated units (200) can be made up of two L-type unit (20a, 20b) and some support units (30a-c).In an optimum embodiment, described support unit (30a-c) is columniform, forms an annulus.Use arch brace unit (30a-c) that integrated convenience, aesthetic property and cost efficiency can be improved.The height of described support unit (30a-c) preferably with described elongated units (200), namely the thickness at described top is identical.

Although in described optimum embodiment, described support unit (30a-c) is circular ring type substantially, and it also can adopt other shapes, cylindrical or cast, as long as the structural strength of described support unit (30a-c) can ensure.Described support unit (30a-c) can be square sectional, solid section, hexagonal cross-section etc.

In order to form an elongated units (200), the described support unit (30a-c) of described elongated units (200) arranges along axle (25), two L-type unit (20a, 20b) preferably arrange face-to-face, an inside face part for described L-type unit (20a, 20b) contacts with an outside face part for described support unit (30a-c).Described L-type unit (20a, 20b) is along axle (25) minute surface distribution mutually.Described L-type unit (20a, 20b) is arranged along such direction, the top of described support unit (30) and side can be covered, and can make the upper surface that described elongated units (200) formation one is smooth like this.Such arranged direction design is conducive to provide pallet (100) smooth upper surfaces and carrys out bearing goods.

As shown in Figure 2 a, although likely adopt this layout, but described support unit (30) must not be close to layout, i.e. the contacting with a part for described L-type unit (20a, 20b) inside face at least partially of each support unit (30) outside face.Must side by side arrange owing to not limiting described support unit (30), described pallet of the present invention has quality light, the advantage that the cost of material is low.

In an optimum embodiment, two support units (30a, 30b) are in the upper adjacent distributions of axle (25), and both outside faces have at least a part to contact with each other.When axle (25) adding the 3rd support unit (30c), an adjustable gap can be introduced.When another adds axle (25) to adjacent support unit (30a, 30b), another gap can be introduced, as shown in Figure 2 a.In an optimum embodiment, the described support unit (30) of described elongated units (200) adopt identical can repeat pattern.Described some elongated units (200) are arranged in parallel, and form top platform.

As shown in Figure 2 a, in an optimum embodiment, the structure of described beam (300) is as follows: the upper described support unit (40) of beam (300) arranges at the upper line of axle (35) of beam, 4 L-type unit (20c-f) are symmetrical, and around the axle (35) of beam, described support unit (40) is wrapped up, form the corner of the basic square-section of described beam (300).The described support unit (40) of described beam (300) can adopt any shape, as long as can ensure the structural strength of described support unit (40).In an optimum embodiment, the described support unit (40) of described beam (300) is cylindrical unit, and the support unit (30a-c) in elongated units (200) described in cylinder aspect ratio wants high.The height of described support unit (40) is identical with the thickness of described bottom, and will match with the jaw thickness of fork truck, in the gap that jaw so just can be made to insert between two continuous beams (300).

Similar to described elongated units (200), although likely adopt this layout, but described support unit (40) must not be close to layout, i.e. the contacting with a part for described L-type unit (20c-f) inside face at least partially of each support unit (40) outside face.

In an optimum embodiment, as shown in Figure 2 a, described support unit (40) is arranged in such a way, and each support unit (40) can be made to support a wherein elongated units (200), and elongated units (200) runs through in mode crossing in length and breadth with some beams (300).Like this, described continuous support unit (40) can not contact with each other, namely separately arrangement.Therefore, the distance between continuous parallel elongated units (200) is identical with the distance between the upper continuous support unit (40) of described beam (300).

As shown in Figure 2 a, in a preferred embodiment, the arrangement mode like this of described support unit (30a-c, 40), a support unit (40) of described beam (300) can be made to support upper two the adjacent support units (30a, 30b) of described elongated units (200).Every root beam (300) preferably can be located immediately at immediately below upper two the adjacent support units (30a, 30b) of the described elongated units (200) of arranged in parallel.The arrangement structure of even now is not indispensable, but when goods is placed on the some elongated units in top (200), the pressure energy described L-type unit (20a of Shangdi in described elongated units (200) more produced, 20b) and described support unit (30a-c, 40) disperse on to transmit, thus improve the structural strength of described pallet (100).

Two to adjacent support unit (30a, described support unit (30c) is placed 30b), this is done to provide larger rigidity to described elongated units (200), when the jaw of fork truck contacts with the lower surface of described elongated units (200) in transportation, the pressure that it produces can be adjusted.The existence of described support unit (30c) can prevent these elongated units (200) from flattening, and keeps its rigidity.

But in other embodiments, the support unit (30) of described elongated units (200) can be arranged to the form be separated from each other, and does not have adjacent support unit (30a, 30b).In this embodiment, a support unit (40) of described beam (300) supports a support unit (30) of described elongated units (200).

The another kind realizing such arrangement may be structurally combined by described support unit (30,40), forms a higher support unit, like this can without the L-type unit (20c, 20d) on upper strata.These embodiments can directly reach cost-saving object.In order to increase the rigidity of structure of this embodiment, around higher support unit, place shorter L-type unit, come local envelopment it, further support described elongated units (200).

In a further advantageous embodiment, bidirectional plate frame (100) as shown in Figure 2 a can be configured to the pallet (not shown) that a four-way enters.Fig. 3 a is depicted as described two to the birds-eye view entering pallet (100).The pallet that four-way enters must be able to allow the jaw of fork truck from the direction of arrow as shown in fig. 3a, and in pallet four limit, any direction enters.Form four-way and enter pallet, the L-type unit (20e, 20f) of described two bottoms does not preferably adopt in the fitting process of pallet.Described like this pallet is supported alone by the described support unit of impartial separation mutually as shown in Figure 2 b.Without the L-type unit (20e, 20f) of bottom, the jaw of fork truck also can penetrate pallet from direction, the left and right sides, as shown in Figure 3 a, so just this pallet has been transformed into four-way pallet.But, in order to improve the structural strength of this optimum embodiment, the support unit (highly lower) in described elongated units adds along described beam direction between coherent support unit.These support units added will be positioned on two L-type unit (20c, 20d) and beam between two continuous print support units, to increase the rigidity of described beam, and prevent L-type unit (20c, 20d) to be crushed.Enter when forklift and contact with described L-type unit (20c, 20d), and lifting pallet, when transport is positioned at the goods in some elongated units, these support units of increase can ensure that this did not lose efficacy to L-type unit (20c, 20d).Double stacking in order to four-way can be allowed to enter pallet, the lower surface of support unit (40) then covers with shorter L-type unit.

Because the present invention only forms, so other embodiment is also possible with support unit (30, the 40) structure of some L-type unit (20) and some differing heights.

In another embodiment, the L-type unit (20e, 20f) of bottom is not included, as shown in Figure 2 b, to reduce cost of raw materials used.

In another embodiment, described pallet (100) can be formed by some L-type unit (20), Multi-layers distributing between them, and mutually tight sticky, to increase the thickness of described L-type unit (20), thus increases the intensity of described pallet (100).

Also having in some embodiments, paired L-type unit (20a and 20b, 20c and 20d, 20e and 20f) can form the U-shaped unit of formation, and does not affect the structural strength of described pallet.Described support unit (40) is enclosed in interior described L-type unit (20c-f) also to substitute with a rectangular element.

In another embodiment, L-type unit is increased at the opposite side of described top section, vertical with some elongated units (200), the mode wrapped by the cross-sectional plane exposed by upper for described elongated units (200) L-type unit (20a, 20b) increases the intensity of described pallet (100).

In another embodiment, one piece of millboard, or fluted cardboard or lamination millboard, can be placed on described pallet (100), be covered in the upper surface of described some elongated units (200).The space that the elongated units be arranged in parallel (200) can be formed by placement millboard and hole seam override, make the goods that can transport reduced size on described pallet (100) like this, in transportation or fork truck lift in process, prevent goods from dropping from the seam pallet.Meanwhile, millboard also can help being uniformly distributed of cargo load.
