Description

Pallet

The present invention relates to a pallet, especially a pallet with elastic pieces of different densities.

In the logistics field, pallets are mostly used as a means of transporting large goods. In addition to facilitating the operation of lifting equipment such as stackers or pallet trucks, the pallet also has the advantage of being able to accommodate various shapes of goods, thus improving the efficiency of logistics.

However, most of the conventional pallets do not have a buffer device. If you encounter the need to transport large and collision-resistant goods such as server cabinets, it is easy to cause vibration or impact to the goods when moving the conventional pallets, which may cause damage to the goods.

The present invention is to provide a pallet, so as to solve the problem that the conventional pallet in the prior art is not easy to provide buffer protection for the carried goods during transportation.

The pallet disclosed in an embodiment of the present invention includes a first plate body, a second plate body, a first elastic member, and a second elastic member. The first elastic element and the second elastic element are arranged between the first plate and the second plate, and the second elastic element is closer to an edge of the second plate than the first elastic element. The density of the second elastic element is greater than the density of the first elastic element.

According to the pallet disclosed in the above embodiment, the first elastic member has a relatively low density and has a relatively large amount of deformation, while the second elastic member and the third elastic member have a relatively high density and have a relatively small amount of deformation. Therefore, the first elastic element can have better shock absorption capability than the second elastic element and the third elastic element, and can be used as the main cushion between the first plate body and the second plate body; and the second elastic element The connection relationship between the first plate body and the second plate body can be stabilized with the third elastic member.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

An embodiment of the present invention will be described below. First, please refer to FIG. 1 and FIG. 2. FIG. 1 is a three-dimensional schematic diagram of a pallet 10a according to an embodiment of the present invention. Fig. 2 is an exploded schematic diagram of the pallet 10a of Fig. 1.

The pallet 10a of this embodiment includes a first plate body 100a, a second plate body 200a, at least one first elastic element 300a, and at least one second elastic element 400a. When the pallet 10a is placed on a platform such as the ground, the first plate 100a is closer to the platform than the second plate 200a, and the second plate 200a is used to carry heavy objects (not shown), for example. The present invention is not limited to the placement mode of the pallet 10a. In some embodiments, the pallet can also be placed in a way that the second board is closer to the platform than the first board, and the first board is used to carry heavy objects.

In this embodiment, the first elastic member 300a is disposed between the first plate body 100a and the second plate body 200a in a pasting manner, for example. The second elastic member 400a is disposed between the first plate body 100a and the second plate body 200a in an adhesive manner, for example. In this embodiment and some embodiments of the present invention, the pallet 10a may further include at least one third elastic member 500a. The third elastic member 500a is disposed between the first plate body 100a and the second plate body 200a in an adhesive manner, for example. In this embodiment, the second elastic element 400a is closer to an edge 201a of the second plate 200a than the first elastic element 300a. In this embodiment and some embodiments of the present invention, the third elastic member 500a is farther away from the edge 201a of the second board 200a than the first elastic member 300a. That is, the first elastic member 300a is located between the second elastic member 400a and the third elastic member 500a.

In this embodiment and some embodiments of the present invention, the number of each of the first elastic element 300a, the second elastic element 400a, and the third elastic element 500a is multiple, but the present invention is not limited thereto. In some embodiments, the number of each of the first elastic element, the second elastic element, and the third elastic element may be only one.

In this embodiment and some embodiments of the present invention, the thickness of the first elastic element 300a, the second elastic element 400a, and the third elastic element 500a between the first plate body 100a and the second plate body 200a is, for example, Between 75 and 78 millimeters (mm). The material of the first elastic member 300a, the second elastic member 400a and the third elastic member 500a is, for example, expanded polyethylene (commonly known as EPE pearl cotton, expanded polyethylene), which can be restored to its original shape after receiving a certain degree of external force. Therefore, the first elastic element 300a, the second elastic element 400a, and the third elastic element 500a can serve as a buffer between the second plate 200a and the first plate 100a, so that the weight carried by the second plate 200a is not easy to carry. Received the impact from the platform.

In this embodiment, the density of the second elastic element 400a is greater than the density of the first elastic element 300a. In this embodiment and some embodiments of the present invention, the density of the third elastic element 500a is greater than the density of the first elastic element 300a. Specifically, the density of the first elastic element 300a is, for example, 4 pounds per cubic foot, and the density of the second elastic element 400a and the third elastic element 500a is, for example, 6 pounds per cubic foot. Therefore, when the first elastic element 300a, the second elastic element 400a, and the third elastic element 500a are subjected to the same force, the first elastic element 300a has a lower density and deforms more, while the second elastic element 400a is The third elastic member 500a has a relatively small deformation due to its relatively high density. Therefore, the first elastic member 300a can have better shock absorption capability than the second elastic member 400a and the third elastic member 500a, and can be used as a main cushion between the first plate body 100a and the second plate body 200a; The second elastic member 400a and the third elastic member 500a can stabilize the connection relationship between the first plate body 100a and the second plate body 200a. In some embodiments, the density of the first elastic element, the second elastic element, and the third elastic element can also be increased or decreased simultaneously according to the weight of the weight carried by the second plate.

Please refer to Figure 1 and Figure 3 together. FIG. 3 is a perspective view of the first elastic member 300a of the pallet 10a in FIG. 1. As shown in the figure, in this embodiment and some embodiments of the present invention, the first elastic member 300a may include at least two sheet members AA and BB that have the same shape and size and are fixed to each other in an adhesive manner. For example, when a first elastic member 300a with a width of 80 mm needs to be provided between the first plate body 100a and the second plate body 200a, for example, 80 mm EPE pearl cotton material can be selected, and the 80 mm The EPE pearl cotton material is cut into the shape of the first elastic member 300a; or, for example, two 40 mm EPE pearl cotton materials can be used, and the two 40 mm EPE pearl cotton materials can be cut into pieces. Shape the shapes of AA and BB, and then glue and fix the sheet AA and BB to each other. That is to say, by pasting the two sheet-like members AA and BB, another method for forming the first elastic member 300a is provided, so there is more choice in selecting the size of EPE pearl cotton material. In addition, the second elastic element 400a and the third elastic element 500a may also include at least two sheet-like elements with the same shape and size and fixed to each other in a pasting manner, which are formed in the same manner as the first elastic element 300a, and will not be repeated here. . The present invention is not limited to the manner in which the first elastic element 300a, the second elastic element 400a, and the third elastic element 500a are formed. In some embodiments, it is also possible to cut a single EPE pearl cotton material to form the first elastic element, the second elastic element or the third elastic element.

In this embodiment and some embodiments of the present invention, the first elastic member 300a has at least one groove 301a and at least one convex portion 302a. Specifically, the first elastic member 300a has two grooves 301a and three protrusions 302a, but the number of grooves 301a and protrusions 302a of the present invention is not limited thereto. In this embodiment and some embodiments of the present invention, the groove 301a is located between the convex portions 302a, and both the groove 301a and the convex portion 302a face the second board 200a. The area of the convex portion 302a on the side close to the second plate body 200a is smaller than the area of the convex portion 302a on the side close to the first plate body 100a. When the first elastic member 300a is squeezed by the second plate 200a, the groove 301a provides a space for the protrusion 302a to deform. Therefore, the first elastic member 300a is not easily deformed to the outside after being impacted, so that the first elastic member 300a is After the impact is buffered and removed, it can be restored to its original shape. In addition, the second elastic element 400a and the third elastic element 500a may also have grooves or protrusions. The functions of the grooves and protrusions of the second elastic element 400a and the third elastic element 500a are the same as those of the first elastic element 300a. The functions of the groove 301a and the convex portion 302a are the same, and will not be repeated here. However, the present invention is not limited to the grooves 301a and protrusions 302a of the first elastic element 300a or the grooves and protrusions of the second elastic element 400a and the third elastic element 500a. In some embodiments, the first elastic element, the second elastic element, or the third elastic element may not have grooves or protrusions.

Please refer to Figure 4. FIG. 4 is a three-dimensional schematic diagram of a pallet 10b and a ramp 20b drawn according to another embodiment of the present invention. The following will only describe the differences between another embodiment of the present invention and some of the foregoing embodiments, and the remaining similarities will be omitted. In this embodiment and some embodiments of the present invention, the pallet 10b may further include at least one first adhesive member 600b. The first adhesive member 600b is, for example, two pieces of ring-shaped devil felt and is disposed on a side of the second board 200b away from the first board 100b. The first adhesive member 600b can be used to connect a slope 20b.

The purpose of the slope 20b is to facilitate the movement of the heavy objects on the second board 200b onto the platform. The structure of the slope 20b will be described in detail below. Please refer to Figure 4 and Figure 5 together. FIG. 5 is an exploded schematic diagram of the slope 20b in FIG. 4. The slope 20b includes at least one first lower fixing plate 21b, at least one second lower fixing plate 22b, at least one bearing block 23b, an upper bearing plate 24b, at least one second adhesive member 25b, and at least one side strip 26b. When the slope 20b is placed on a platform such as the ground, the first lower fixing plate 21b and the second lower fixing plate 22b are closer to the platform than the load-bearing block 23b. The purpose of the first lower fixing plate 21b and the second lower fixing plate 22b will be described later. The load-bearing blocks 23b are, for example, four long wedge-shaped wooden blocks and are arranged on the first lower fixing plate 21b and the second lower fixing plate 22b. The upper bearing plate 24b is arranged on the inclined surface of the bearing block 23b away from one side of the first lower fixing plate 21b and the second lower fixing plate 22b. The second adhesive member 25b is, for example, two pieces of hook-shaped devil felt corresponding to the first adhesive member 600b and is arranged on the side of the upper bearing plate 24b away from the bearing block 23b. In this way, the slope 20b can be easily and quickly connected to the second board 200b by the second adhesive member 25b and the first adhesive member 600b. The side bars 26b are, for example, two long wooden bars and are arranged on the side of the upper bearing plate 24b away from the bearing block 23b along the oblique direction of the upper bearing plate 24b.

By sticking the second sticking piece 25b to the first sticking piece 600b, the slopes 20b can be fixed side by side on one side of the second plate 200b to facilitate the movement of the weight on the second plate 200b to the upper load bearing板24b. When the weight moves to the upper load-bearing plate 24b, the load-bearing block 23b can be used as a support between the upper load-bearing plate 24b and the platform to prevent the slope 20b from collapsing and deforming, and the side bars 26b can guide the moving direction of the weight and prevent the weight Fall from slope 20b. The first lower fixing plate 21b and the second lower fixing plate 22b can fix a plurality of load-bearing blocks 23b to prevent the arrangement of the plurality of load-bearing blocks 23b from changing, so that the supporting force of the load-bearing blocks 23b can be ensured enough.

Please refer to Figure 6 and Figure 7. Fig. 6 is a schematic side view of the slope 20b of Fig. 4. FIG. 7 is a partial enlarged schematic diagram of the slope 20b in FIG. 6. In this embodiment and some embodiments of the present invention, the bearing block 23b may have an uneven surface design on the side facing the first lower fixing plate 21b. Therefore, when the slope 20b is placed on the platform and the upper bearing plate 24b has not yet carried heavy objects, as shown in FIG. 7, the first lower fixing plate 21b provided on the uneven surface of the bearing block 23b may be different from the platform. D1.

In this case, when the upper load-bearing plate 24b carries a heavy object, the weight of the weight causes the uneven surface of the load-bearing block 23b to slightly deform toward the platform, so that the first lower fixing plate 21b is aligned with the platform; When the weight carried by the plate 24b is removed, the load-bearing block 23b returns to the original uneven surface on the side facing the first lower fixing plate 21b, so that the first lower fixing plate 21b will return to the same level as the platform. There is a distance of D1 between them.

Therefore, the level difference D1 can be regarded as a reserved deformation amount when the upper load-bearing plate 24b carries a heavy object. If the slope 20b does not have a design with a step difference D1, when the upper bearing plate 24b is squeezed by an overweight object, the deformation of the upper bearing plate 24b in the middle area may cause the upper bearing plate 24b to be on the side away from the second adhesive member 25b ( That is, the upper bearing plate 24b is plastically deformed in a direction away from the platform, which is not conducive to moving objects carried by the upper bearing plate 24b to the platform, or moving objects from the platform to the upper bearing plate 24b. Therefore, the above-mentioned problems can be avoided by the design of the level difference D1.

Please refer to Figure 8 and Figure 9. FIG. 8 is a three-dimensional schematic diagram of a pallet 10c according to still another embodiment of the present invention. FIG. 9 is an exploded schematic diagram of the pallet 10c of FIG. 8. In the following, only the differences between another embodiment of the present invention and some of the foregoing embodiments will be described, and the remaining similarities will be omitted. In this embodiment and some embodiments of the present invention, the second plate body 200c may further include a first bearing plate 210c and a second bearing plate 220c. The first load-bearing plate 210c and the second load-bearing plate 220c are, for example, laminated veneer lumber, or plywood, and are arranged side by side on the first elastic member 300c, the second elastic member 400c, and the third elastic member 500c away from the first plate body 100c One side. The area of the largest surface of the first bearing plate 210c is larger than the area of the largest surface of the second bearing plate 220c. The size of the largest surface of the first bearing plate 210c is, for example, 1220 mm×880 mm, and the size of the largest surface of the second bearing plate 220c is, for example, 880 mm×180 mm. Since the standard size of common plywood materials is 2440 mm × 1220 mm, in addition to being cut into a second board 200c with a size of 1400 mm × 880 mm, it can also be cut into two sets of sizes of 1220. The first load-bearing plate 210c and the second load-bearing plate 220c are mm×880 mm and 880 mm×180 mm. In other words, cutting the plywood material into two sets of the first load-bearing board 210c and the second load-bearing board 220c to form the second board 200c is more flexible than cutting the plywood material directly into one second board 200c. , But not limited to this. In some embodiments, the first bearing plate and the second bearing plate can also be integrally formed.

In this embodiment and some embodiments of the present invention, the second plate body 200c may further include two third bearing plates 230c and a fourth bearing plate 240c. The third bearing board 230c is, for example, a polypropylene board (Polypropylene Board). The fourth load-bearing board 240c is, for example, a high density fiber board (High Density Fiber Board) and is located between the third load-bearing boards 230c. The third bearing plate 230c and the fourth bearing plate 240c are arranged side by side on a side of the first bearing plate 210c and the second bearing plate 220c away from the first plate body 100c. The hardness of the third bearing plate 230c is greater than the hardness of the first bearing plate 210c, the hardness of the second bearing plate 220c, and the hardness of the fourth bearing plate 240c. Since the weight carried by the second plate 200c may be equipped with wheels at the four corners of the bottom (for example, a server rack), when the second plate 200c is carrying heavy objects, the weight of the heavy objects is likely to concentrate on The area of the third bearing plate 230c where the four wheels are located. Therefore, in the design, the third load-bearing plate 230c is made of a material with higher hardness to keep the surface of the third load-bearing plate 230c smooth and not easy to be deformed, so that the weight can move on the second plate body 200c.

In this embodiment and some embodiments of the present invention, the second plate body 200c may further include at least one fixing bar 250c. The fixing bar 250c is, for example, two wooden bars and is arranged on a side of the third load-bearing plate 230c and the fourth load-bearing plate 240c away from the first board body 100c. The fixing bar 250c can be fixed to the third bearing plate 230c and the fourth bearing plate 240c by screwing, and the first bearing plate 210c and the second bearing plate 220c can be fixed to the third bearing plate 230c and the fourth bearing plate 230c and the fourth bearing plate. Load-bearing plate 240c.

In this embodiment and some embodiments of the present invention, the first plate body 100c may further include at least one first fixing plate 110c and at least one second fixing plate 120c. The first fixing plate 110c and the second fixing plate 120c partially overlap and are arranged on a side of the first elastic member 300c and the second elastic member 400c away from the second plate body 200c. The area of the largest surface of the first fixing plate 110c plus the area of the largest surface of the second fixing plate 120c is smaller than the area of the largest surface of the second plate body 200c. The first fixing plate 110c and the second fixing plate 120c can support the first elastic element 300c, the second elastic element 400c, and the third elastic element 500c without using too much material, and maintain the overall structure of the first plate body 100c strength.

In this embodiment and some embodiments of the present invention, the pallet 10c may further include at least one spacer 700c. The second elastic member 400c may further have an accommodating space 401c on the side away from the first elastic member 300c, and the third elastic member 500c may further have an accommodating space 501c on the side away from the first elastic member 300c. The spacer 700c is, for example, a plurality of wooden blocks. Part of the spacer 700c is disposed in the accommodating space 401c of the second elastic member 400c and between the second elastic member 400c and the first plate 100c, while the remaining spacer 700c is disposed in the accommodating space 401c of the third elastic member 500c. The set space 501c is located between the third elastic member 500c and the first plate body 100c. When a forklift (not shown) needs to be used to move the pallet 10c, because the spacer 700c is set at the same level as the fork arm of the forklift, the spacer 700c can prevent the fork arm from directly colliding with the second elastic The element 400c or the third elastic element 500c can further prevent the second elastic element 400c or the third elastic element 500c used as a cushioning material from deforming and affecting the cushioning ability.

According to the pallet of the above-mentioned embodiment, the first elastic member has a relatively low density and has a relatively large amount of deformation, while the second elastic member and the third elastic member have a relatively high density and have a relatively small amount of deformation. Therefore, the first elastic element can have better shock absorption capability than the second elastic element and the third elastic element, and can be used as the main cushion between the first plate body and the second plate body; and the second elastic element The connection relationship between the first plate body and the second plate body can be stabilized with the third elastic member.

In some embodiments, the first elastic member has grooves and protrusions. When the first elastic member is squeezed by the second plate, the groove provides space for the protrusion to deform. Therefore, the first elastic member is not easily deformed to the outside after receiving the impact force, so that the first elastic member can buffer and move the impact force. After being removed, it can be restored to its original shape.

In some embodiments, the pallet may further include a first sticker. The first sticker can be used to connect the slope. In this way, the second plate body can be connected to the slope simply and quickly by the first adhesive member, so that the weight on the second plate body can be moved to the platform through the slope conveniently.

In some embodiments, the third load-bearing plate is designed with a material with higher hardness to keep the surface of the third load-bearing plate smooth and not easy to be dented and deformed, so that the weight can move on the second plate.

In some embodiments, the pallet may further include spacers. When a forklift is needed to move the pallet, because the position of the spacer block is just at the same level as the fork arm of the forklift, the spacer block can prevent the fork arm from directly colliding with the second elastic member or the third elastic member. It can avoid the deformation of the second elastic member or the third elastic member used as a buffer material to affect the buffer capacity.

Although the present invention is disclosed in the foregoing embodiments as above, it is not intended to limit the present invention. Anyone familiar with similar art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of patent protection for inventions shall be determined by the scope of patent applications attached to this specification.
