Description

Eco-friendly paper pallet

The present invention relates to a pallet for loading and moving objects, and to an environmentally friendly and lightweight paper pallet.

In general, when heavy objects that are difficult for people to transport in industrial sites, etc. need to be transported, a forklift is used. When transporting objects with a forklift, the objects pile up, and a pallet designed for easy transport by a forklift is essential. Such pallets are economical and require good assembly and marketability. Conventionally used pallets had limitations in the processing process, processing method, and materials, and there were many problems such as poor condition when transporting objects and inconvenience in use.

Specifically, pallets such as wood assembly and plastic molding have been used, but they have the following problems. That is, first, in the case of wood assembly type pallets, since they are made of wood, they cannot be recycled, the upper part that accommodates the goods and the support and lower part located at the bottom of the upper part are made of wood, so the manufacturing cost is high, and since many fastening members (nails) that connect each member must be used, the cost is high, and since the structure is complex, the work time for manufacturing and disassembling is long, and the labor cost is high accordingly, there are disadvantages.

Second, plastic molded pallets can be mass-produced and have advantages in terms of cost and time savings due to shorter processing times, but they are made of plastic, so their production costs are very high and they are heavy, making them inconvenient to transport.

That is, conventional pallets have the problem that their structure is complex during manufacturing, which requires a lot of manufacturing time and cost, they can cause inconvenience to users during use and transportation due to poor bonding, and they cannot be recycled, which can cause environmental pollution.

Fig. 1 is a perspective view of an eco-friendly paper pallet according to one embodiment of the present invention. Fig. 2 is an exploded perspective view of an eco-friendly paper pallet according to one embodiment of the present invention. Referring to Figs. 1 and 2, an eco-friendly paper pallet according to one embodiment of the present invention may include a first lower support portion (1), a second lower support portion (2), a joint tube (3), a joint portion (6), and a receiving portion (7).

A plurality of first lower support members (1) can be arranged along the first direction (A1). Specifically, the first lower support members (1) can be provided in a rectangular solid shape and can be arranged at equal intervals along the first direction (A1).

The second lower support member (2) is secured to the first lower support member (1) and may be arranged in multiple numbers along the second direction (A2). Specifically, the second lower support members (2) may be provided in a rectangular solid shape and may be arranged at equal intervals along the second direction (A2).

The first direction (A1) and the second direction (A2) can be orthogonal. Accordingly, the first lower support member (1) and the second lower support member (2) are arranged orthogonally so that when an object is stacked on the upper plate (5) described later, the load is evenly distributed, thereby increasing the structural rigidity, and the weight of the entire eco-friendly paper pallet (P) can be minimized.

For example, in Fig. 1, the first direction (A1) is depicted as moving away from the center in a right diagonal direction, and the second direction (A2) is depicted as moving away from the center in a left diagonal direction. However, the first direction (A1) and the second direction (A2) should not be interpreted in a restrictive manner as they can be set in various ways depending on the viewing angle.

In addition, the first lower support member (1) may be provided with a short side of 0.15 to 0.17 of the long side, and the second lower support member (2) may have the same short side and long side length as the first lower support member (1). Specifically, the first lower support member (1) may be provided with a short side of 160 mm and a long side of 1010 mm.

Accordingly, when using a forklift, an eco-friendly paper pallet (P) can be designed with an optimal size suitable for a forklift, and the weight can be minimized while maintaining structural safety.

A plurality of connecting pipes (3) can be provided and mounted on the second lower support member (2). Specifically, the connecting pipes (3) can be arranged at equal intervals along the first direction (A1) and the second direction (A2), and an upper plate (5) to be described later can be mounted on the upper portion.

That is, the connecting pipe (3) connects the lower support part (B) composed of the first lower support part (1) and the second lower support part (2) and the upper plate (5), and a space is formed between each connecting pipe (3) so that a forklift of a forklift can be placed.

In addition, the joint pipe (3) can be provided in an overall cylindrical shape, so that interference can be minimized when a forklift truck enters compared to a rectangular solid shape, and the upper plate (5) can be effectively supported.

The upper plate (5) can be mounted on the connecting tube (3). That is, the upper plate (5) can be provided in a plate shape so that objects can be easily mounted and stacked. Specifically, the lower surface of the upper plate (5) can be combined with the connecting tube (3), and objects to be stacked can be mounted on the upper surface.

Specifically, the upper plate (5) may be provided in a rectangular hexahedron shape, and further may be provided in a regular hexahedron shape. That is, the upper plate (5) is a flat plate shape, and is provided with a square cross section, so that the load of an object can be prevented from being concentrated on a specific part when transported by a forklift. For example, the upper plate (5) may have a square shape with a side length of 1100 mm.

The connecting portion (6) can penetrate the first lower support portion (1), the second lower support portion (2), the connecting tube (3) and the upper plate (5), and the receiving portion (7) can be connected to the connecting portion (6) on the lower side of the first lower support portion (1) to fix the connecting portion (6).

That is, the joint part (6) and the receiving part (7) can integrally bind the first lower support part (1), the second lower support part (2), the joint pipe (3), and the upper plate (5), so that the manufacturing process is simplified and costs can be reduced by not using a separate adhesive, etc.

In addition, the joint part (6) and the receiving part (7) are provided in the same number as the joint pipe (3) to fix the entire eco-friendly paper pallet (P), so that the number of separate parts for jointing can be minimized compared to a wooden pallet.

For example, the connecting portion (6) is provided with a bolt and can be inserted through the upper plate (5), and the receiving portion (7) is provided with a thorn nut to secure the connecting portion (6) at the bottom of the first lower support portion (1), so that exposure to the outside can be minimized.

That is, the joint part (6) can be inserted from the upper side of the eco-friendly paper pallet (P), making it easy to manufacture, and the receiving part (7) is positioned at the lower side, minimizing exposure to the outside, thereby improving the overall appearance, and minimizing contact with objects placed on the upper surface of the upper plate (5).

Fig. 3 is a top view of an eco-friendly paper pallet according to one embodiment of the present invention. Fig. 4 is a side cross-sectional view of an eco-friendly paper pallet according to one embodiment of the present invention. Referring to Figs. 3 and 4, the joint pipe according to one embodiment of the present invention may include an outer pipe (31) and an inner pipe (33).

The outer branch pipe (31) may be provided in a hollow cylindrical shape. That is, the outer branch pipe (31) may be provided in a hollow shape to minimize weight, and may be placed at the outermost portion so as to be visually confirmed.

The inner branch pipe (33) is arranged inside the outer branch pipe (31) and may be provided in a hollow cylindrical shape. In addition, the outer surface of the inner branch pipe (33) is arranged at a predetermined distance from the inner surface of the outer branch pipe (31) and may have the same center as the outer branch pipe (31).

Accordingly, the outer branch pipe (31) and the inner branch pipe (33) can effectively support the load of the upper plate (5) and the object loaded on the upper plate (5) while minimizing the weight of the entire joint pipe (3), thereby increasing structural safety.

The thickness (T4) of the inner branch pipe (33) may be provided as 0.2 to 0.3 of the thickness (T5) of the outer branch pipe (31). That is, the thickness (T4) of the inner branch pipe (33) may be provided as smaller than the thickness (T5) of the outer branch pipe (31), thereby effectively distributing the applied load while minimizing the overall weight of the joint pipe (3), thereby maintaining structural rigidity. Specifically, the thickness (T4) of the inner branch pipe (33) may be provided as 2 mm (2t), and the thickness (T5) of the outer branch pipe (31) may be provided as 5 mm (5t).

In addition, the height (H1) of the inner branch pipe (33) can be set to 0.67 to 0.78 of the height (H2) of the outer branch pipe (31). That is, the inner branch pipe (33) can be spaced apart from the lower surface of the upper plate (5) to form a space, and a connecting fixing member (9) to be described later can be arranged in the formed space, thereby enabling a compact configuration.

Specifically, the height (H1) of the inner branch pipe (33) can be set to 70 mm, and the height (H2) of the outer branch pipe (31) can be set to 97 mm. Accordingly, the structural safety of the entire joint pipe (3) can be effectively secured while efficiently arranging the configuration within the outer branch pipe (31).

In addition, the outer diameter (D1) of the inner branch pipe (33) may be set to 0.83 to 0.9 of the outer diameter (D2) of the outer branch pipe (31). Accordingly, as described above, the weight of the entire joint pipe (3) may be reduced while ensuring structural safety, and the outer branch pipe (31), the inner branch pipe (33), and the entire joint fixing part (9) may distribute the load evenly by the joint fixing part (9) described later. Specifically, the outer diameter (D1) of the inner branch pipe (33) may be set to 130 mm, and the outer diameter (D2) of the outer branch pipe (31) may be set to 140 mm.

Meanwhile, the eco-friendly paper pallet (P) according to one embodiment of the present invention may further include a rigid support member (4). The rigid support member (4) may be arranged inside the outer tube (31) to increase the structural rigidity of the connecting tube (3).

Specifically, the rigid support member (4) is installed on the upper part of the inner branch pipe (33) and can support the outer branch pipe (31) by coming into contact with the inner surface of the outer branch pipe (31). In addition, the rigid support member (4) can be fixed by being fitted to the inner surface of the outer branch pipe (31), and the supporting force can be maximized.

In addition, the rigid support member (4) can be penetrated by the joint member (6), and the joint member (6) can be fitted into the center of the rigid support member (4) to fix the position. That is, the rigid support member (4) can be in contact with the outer branch pipe (31), the inner branch pipe (33), and the joint member (6) and support each other to distribute the weight and effectively fix the position.

More specifically, the rigid support member (4) is provided in a circular plate shape, and the height (H3) of the rigid support member (4) can be provided to be 0.045 to 0.055 of the height (H2) of the outer branch pipe (31). That is, the upper surface of the rigid support member (4) can be provided spaced apart from the lower surface of the upper plate (5).

Accordingly, the rigid support member (4) can effectively minimize the weight of the entire joint pipe (3) while maintaining the structural safety of the entire joint pipe (3). For example, the height (H3) of the rigid support member (4) can be 5 mm (5 t).

Meanwhile, the thickness (T2) of the second lower support part (2) may be provided to be 0.75 to 0.92 of the thickness (T1) of the first lower support part (1). That is, the first lower support part (1) may be provided to have a thickness thicker than the second lower support part (2).

The first lower support part (1) is the part that directly touches the ground and is made thicker than the second lower support part (2) to increase structural safety, and the second lower support part (2) is made to have a minimized weight to minimize the weight of the entire eco-friendly paper pallet (P).

Specifically, the thickness (T1) of the first lower support member (1) is provided as 6 mm (6t), and the thickness of the second lower support member (2) is provided as 5 mm (5t), so that both structural safety and weight minimization can be achieved.

In addition, the thickness (T3) of the upper plate (5) may be provided to be 0.25 to 0.42 of the thickness (T1) of the first lower support portion (1). That is, the upper plate (5) may be provided to have a thinner thickness than the first lower support portion (1) and the second lower support portion (2).

Since the upper plate (5) has a wider cross-sectional area than the first lower support portion (1) and the second lower support portion (2), the weight can be effectively distributed even with a thinner thickness, and the weight can be minimized. Specifically, the thickness (T3) of the upper plate (5) is provided as 2 mm (2t), so that both structural safety and weight minimization can be achieved.

As described above, the thickness (T4) of the inner branch pipe (33) may be provided as 0.2 to 0.3 of the thickness (T5) of the outer branch pipe (31). In addition, the thickness (T5) of the outer branch pipe (31) may be provided to be the same as the thickness of the rigid support member (4).

That is, the thickness (T6) of the rigid support member (4) is provided as 5 mm (5t), and is effectively placed in the space between the inner tube (33) and the upper plate (5), thereby maximizing the structural rigidity of the entire joint tube (3) while minimizing the weight of the entire eco-friendly paper pallet (P). The thickness (T6) of the rigid support member (4) may be the same as the height (H3) of the rigid support member (4).

Meanwhile, referring back to FIG. 3, the coupling pipes according to one embodiment of the present invention may be provided in nine pieces. In addition, each of the coupling pipes (3) may be arranged at equal intervals along the first direction (A1) and at equal intervals along the second direction (A2).

That is, in order to support the entire upper plate (5) provided in the shape of a thin hexahedral plate, nine connecting pipes (3) can be provided and arranged at equal intervals along the first direction (A1) and the second direction (A2).

In addition, the minimum separation distance (F1) between the outer branch pipe (31) and the upper plate (5) may be set to be 0.1 or more of the outer diameter (D2) of the outer branch pipe (31). That is, when the outer diameter (D2) of the outer branch pipe (31) is set to 150 mm, the minimum separation distance (F1) between the outer branch pipe (31) and the upper plate (5) may be set to be 15 mm or more.

When the minimum distance (F1) between the outer branch pipe (31) and the upper plate (5) is less than 0.1 of the outer diameter (D2) of the outer branch pipe (31), the outer branch pipe (31) may protrude outside the upper plate (5) due to assembly tolerance, etc.

FIG. 5 is a drawing showing a damper part and a joint fixing part of an eco-friendly paper pallet according to one embodiment of the present invention. Referring to FIG. 5, an eco-friendly paper pallet according to one embodiment of the present invention may further include a damper part (8).

The damper part (8) is mounted on the upper surface of the rigid support part (4) and is arranged to contact the lower surface of the upper plate (5) so as to absorb shock. In addition, the damper part (8) may be provided in multiple pieces and arranged to surround the joint part (6).

That is, when an object is stacked on the upper plate (5), a downward load may suddenly be applied, and the outer branch pipe (31), the inner branch pipe (33), and the rigid support member (4) may be momentarily shocked. This momentary shock may cause damage to the outer branch pipe (31), the inner branch pipe (33), and the rigid support member (4).

The damper part (8) is in contact with all of the outer branch pipe (31), the rigid support part (4), and the upper plate (5) to absorb momentary impact and prevent damage to the outer branch pipe (31), the inner branch pipe (33), and the rigid support part (4) as much as possible. The damper part (8) can be made of paper material like other components, and can also be made of a material that is more elastic than paper. The material of the damper part (8) can be determined in various ways depending on the purpose for which the eco-friendly paper pallet (P) is used.

Meanwhile, the eco-friendly paper pallet according to one embodiment of the present invention may further include a rigidity auxiliary member (E). The rigidity auxiliary member (E) may increase structural safety between the outer branch pipe (31) and the inner branch pipe (33). That is, the rigidity auxiliary member (E) is arranged between the outer branch pipe (31) and the inner branch pipe (33), and may come into contact with the inner surface of the outer branch pipe (31) and the outer surface of the inner branch pipe (33).

Accordingly, when an unexpected impact occurs in the left and right directions, the impact can be absorbed between the outer branch pipe (31) and the inner branch pipe (33), thereby increasing the structural safety of the entire joint pipe (3).

In addition, the stiffening auxiliary member (E) may include a stiffening auxiliary taper member (E1) formed so that one surface facing the inner surface of the outer branch pipe (31) and the other surface facing the outer surface of the inner branch pipe (33) are tapered. The stiffening auxiliary taper member (E1) may allow the stiffening auxiliary member (E) to be fixed in position between the outer branch pipe (31) and the inner branch pipe (33).

Meanwhile, an eco-friendly paper pallet according to one embodiment of the present invention may further include a joint fixing part (9). The joint fixing part (9) is arranged inside the inner tube (33) and may be provided to surround the joint part (6). That is, the joint fixing part (9) may be in contact with both the inner tube (33) and the joint part (6) to absorb an impact that occurs momentarily from the outside, thereby increasing the structural safety of the joint tube (3).

Specifically, the coupling fixing member (9) may include a coupling fixing anchoring member (91) and a coupling fixing taper member (95). The coupling fixing anchoring member (91) may be anchored to the second lower support member (2) and may be in contact with both the inner tube (33) and the coupling member (6). That is, the coupling fixing anchoring member (91) may interconnect various components to effectively disperse external impact.

The coupling fixing center portion (93) extends from the coupling fixing anchor portion (91) toward the upper plate (5) and may be provided with a diameter smaller than that of the coupling fixing anchor portion (91). That is, the coupling fixing center portion (93) may be spaced apart from the inner branch pipe (33) and may be in contact with the coupling portion (6).

The joint part (6) is usually made of metal and can move due to external impact, thereby damaging the inner tube (33) made of paper, etc. Therefore, the joint fixing center part (93) further wraps around the joint part (6) to prevent the joint part (6) from damaging the inner tube (33), etc. as much as possible.

The coupling fixing tapered portion (95) can be formed to taper along the inner surface of the coupling fixing anchor portion (91) and the inner surface of the coupling fixing center portion (93). That is, the coupling fixing tapered portion (95) can increase frictional force with the coupling portion (6) so that the coupling fixing portion (9) can be fixed in position relative to the coupling portion (6).

Meanwhile, the upper plate (5) according to one embodiment of the present invention may include a recessed portion (U). The recessed portion (U) may have an upper surface that is recessed to prevent the joining portion (6) from protruding outward. That is, the joining portion (6) may have a head for assembling, and when an object is stacked on the upper plate (5), the head may come into contact with the object, thereby damaging the object or preventing the object from being stacked evenly.

Accordingly, the indentation (U) can prevent the head of the joint (6) from being exposed to the outside as much as possible, thereby improving the appearance, preventing damage to the object, and enabling the object to be stacked in a balanced manner.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. Therefore, the scope of the rights of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described below but also by equivalents of the claims.
