Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a packing system and more particularly, the present invention relates to a packing system utilizing the structure of the packing system for shock absorption.

2. Description of the Prior Art

The packing of the fragile package is an important issue during the shipping process. If the packing is not secured, the package is easily damaged during the shipping and the manufacture cost is increased. For high precision or fragile electronic devices, such as liquid crystal device (LCD), plasma display device, organic light emitting diode (OLED) display, home theater, lamp and so on, it is especially easy to damage the internal circuit structure or other fragile structure, which causes the cost lost of the products.

As a display device packing shown in FIG. 1a and FIG. 1b, during the product shipping process, the display device panel 70 and the support base 50 are separated from each other. At first, the cushions 22 are filled in the bottom of the box 10. The support base 50, folded in the extremely compressed position, is placed in the cushion 22. A partition 30 is disposed in the top of the support base 50 and is used to isolate the support base 50 and the display device panel 70, which is disposed at the top of the partition 30. As the result, the problem of the support base 50 damaging the display device panel 70 during shipping can be avoided. Finally, the cushions 21 are filled in the top of the display device panel 70 and the packing assignment is done.

With the packing method described above, the protection and the shock absorption rely on the cushions 21, the cushion 22 and the partition 30 filling in the box. Therefore, the thickness and the material of the cushions 21, the cushions 22 and the partition 30 determine the efficiency of the shock absorption effect. In other words, the support base 50 is one of the factors to cause the damage of the display device panel 70. Besides, the structure of the support base 50 includes some springs or other elastic materials, but they can not be utilized as a part of the cushion structure of the integrity packing for shock absorption. Therefore, how to convert the support base 50 from a factor causing damages to the electronic device to a device increasing the efficiency of the shock absorption is the main purpose of the present invention.

SUMMARY OF THE INVENTION

A purpose of the present invention is to provide a packing system with the advantage of economizing the usage of the cushion.

Another purpose of the present invention is to provide a packing system utilizing the structure of the package to provide the shock absorption.

The packing system of the present invention includes a box, a first cushion, a partition, and a first article and a second article to be packed. The box has an internal space and the first cushion is disposed within the internal space. The partition is movably disposed within the internal space and a first space is formed between the partition and the first cushion. The first article is in a less stretching status and stored in the first space. Besides, the first article supports the partition and is movably disposed in the first space. The first cushion is filled in the gap between the first article and the box. The second cushion is disposed in the internal space and the first cushion and the second cushion are disposed in the two sides of the partition. A second space is formed between the second cushion and the partition. The second article is stored in the second space. The second cushion is used to fill in the gap between the electronic device and the box. In the preferred embodiment, the second cushion contacts the partition and covers the electronic device. The first cushion covers the first article and the contacted portion of the partition.

In the preferred embodiment, the first article is a support base. The support base includes a base, a support rod, a connective stand and an elastic member. Two ends of the support rod are respectively opposite to a base end and a sustained end. The base end is connected to the base and the sustained end is movable relative to the base end. The support rod can be in a stretching position, a compressing position, a less stretching position and a less compressing position. The elastic member is respectively connected to the base and the support rod. When the support base is in the stretching position, the deformable value and the elastic strength is the smallest. When the support base is in the compressing position, the relative displacement between the support rod and the base is in the maximum value. When the support base is in the less stretching position and the less compressing position, the relative displacement between the support rod and the base is increasable.

When the support base is stored in the first space of the box, the support base is stretchable in a first direction. The support base is against the partition and provides a force for the partition to absorb the shock of the partition during the shipping. When an external force is applied to the second article, the partition is compressed in the first direction. The external force is transmitted along the first direction from the partition to the support base. The support base is moved from the less stretching position to the less compressing position and absorbs the shock and the displacement. At the moment, the elastic member accumulates an elastic strength and the support base can return to the original position, the less stretching position, by the elastic strength. By the stretch of the support base and the elastic strength of the elastic member, the shock of the second article generated by the external force is reduced.

In the preferred embodiment, an elastic material is disposed between the partition and a first interval of the first cushion. By comparing to the partition and the first cushion, the rigidity coefficiency of the elastic material is small. In other words, when the same external force is used, the resistance of the elastic material is smaller than the resistance of the partition and the first cushion. When the partition is compelled along the first direction, because the rigidity coefficiency of the elastic material is smaller, the elastic material will start to be deformed and compressed before the partition and the first cushion do and provide an enough compressing space for the support base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A packing system is disclosed in the present invention. In the preferred embodiment, the packing system is used for an electronic device. In the present invention, a display device is used as an example of the electronic device, as shown in FIG. 2. However, the present invention can also be implemented in other devices or equipment, such as fans, lamps and so on.

As the embodiment shown in FIG. 3a and FIG. 3b, the packing system includes a box 100, a first cushion 220 and a partition 300. The box 100 includes an internal space 110. In the present embodiment, the box 100 is a quadrate box and the internal space 110 is also a quadrate space. However, in a different embodiment, the shape of the box 100 and the internal space 110 can be varied for different types of articles. In accordance with one embodiment, the box 100 is a box made of cardboard. In a different embodiment, the box 100 is made of plastic or other materials.

As shown in FIG. 3a and FIG. 3b, the first cushion 220 is disposed within the internal space 110. The first cushion 220 is made of the Styrofoam. In a different embodiment, the first cushion is made of cushion material, such as foam, organic expandable materials, air pad and so on. The partition 300 is movably disposed in the internal space 110 of the box 100, and the two ends of the partition 300 are contacting the internal wall of the box 100 to maintain the stability of the partition in the horizontal direction. A first interval 221 is maintained between the partition 300 and the first cushion 220. Therefore, the partition 300 and the first cushion 220 are separated from each other. As shown in FIG. 3b, the internal space 110 is divided into a first space 112 and a second space 111 by the partition 300. The first space 112 is formed between the partition 300 and the first cushion 220. The first space 112 includes a first height. Besides, in a preferred embodiment, the rigidity coefficiency of the partition 300 is larger than the rigidity coefficiency of the first cushion 220. In the preferred embodiment, the partition 300 is movably disposed in the internal space 110 through the friction between the box 100 and the partition 300. However, in a different embodiment, the partition 300 is supported by the article stored in the first space 112 and is movably disposed within the box 100.

When the box 100 is impacted or compelled by an external force, the first cushion 220 is moved relative to the partition 300. When the first cushion 220 and the partition 300 are oppositely moved by the compressing force, as shown in FIG. 3c, the box 100 will be deformed and the first interval 221 formed between the first cushion 220 and the partition 300 is compressed to be a second interval 222. The second interval 222 is smaller than the first interval 221, and at this time, the first height of the first space 112 is compressed to be a smaller second height. Besides, in the preferred embodiment, when an external force is compressing, the box 100 starts to deform at the position close to the second interval 222, in order to start its deformation in coordination with the variation of the gap between the first cushion 220 and the partition 300.

FIG. 3d is another embodiment of the partition 300 and a second cushion 210. In this embodiment, two sides of the partition 300 are respectively stretched to the second cushion 210. The second cushion 210 includes a shape looks like a paperboard. The second cushion 210 is contacted to two sides of the extensional portion of the partition 300 and against each other. The second space 111 is formed between two sides of the stretching portion of the partition 300.

As the embodiment shown in FIG. 4a and FIG. 4b, the packing system further includes a first article 500 and a second article 700. The first article 500 is stored in the first space 112. The second article 700 is stored in the second space 111. The first article 500 is a support base with deformable ability and deformable recovery ability. In a different embodiment, the first article 500 can be any other device with deformable ability and deformable recovery ability. The second article 700 can be a display device. In a different embodiment, the second article 700 can be an electric fan, a lamp or any other electronic device. Besides, in the present invention, the second article 700 can be any other non-electronic devices, such as mirror, glass and so on.

In the embodiment, the thickness of the partition 300 is adjustable according to the size of the internal space 110 of the box 100 to vary the sizes of the first space 112 and the second space 111. In the preferred embodiment, the partition 300 is made by Styrofoam. In coordinate with the impact resistance level of the second article 700 and the first article 500, the hardness of the partition 300 is adjustable. For example, a high density of the Styrofoam material is used to be the partition 300. Besides, the partition 300 can have multi-layers structure for increasing the ability of absorbing the shock or for any other purposes. As the embodiment shown in FIG. 5, the partition 300 adds a hardness board 310 along the surface of the first space 112. By adding a hardness board 310, the probability that the partition 300 is harmed or penetrated by hitting is decreased.

As the embodiment shown in FIG. 4a and FIG. 4b illustrates, a second cushion 210 is disposed in the internal space 110 of the box 100. A second space 111 is formed between the second cushion 210 and the partition 300 and stored in the second article 700. The second cushion 210 is disposed against the partition 300 and is used to fill in the gap between the second article 700 and the box 100. When the box 100 is impacted by an external force, the second cushion 210 is not moved relative to the partition 300. In other words, the relative position between the second cushion 210 and the partition 300 is not changed. As shown in FIG. 4b, the second cushion 210 covers the second article 700, except for the portion of the second cushion 210 contacting the partition 300. However, in a different embodiment, the second cushion 210 and the partition 300 are respectively disposed in the top and the bottom of the article 700. Besides, the second cushion 210 is made by Styrofoam. However, in a different embodiment, the second cushion 210 is made by any other cushion material, such as foam, organic expandable materials, air pad and so on.

As the embodiment shown in FIG. 4a and FIG. 4b illustrates, the first article 500 is a support base 501 and is connected with the second article 700 to support the second article 700, wherein the support base 501 can also be separated from the second article 700. As shown in FIG. 4b and FIG. 6a, the support base 501 includes a base 510, a support rod 530, a connective stand 550 and an elastic member 570. Two ends of the support rod 530 are a base end 531 and a sustained end 533. The base end 531 is rotatably connected to the base 510. The sustained end 533 is rotatable to connect the connective stand 550. When the base 510 is set as the reference point, the sustained end 533 is rotated relative to the base end 531. The elastic member 570 is respectively connected to the base 510 and the support rod 530. In the preferred embodiment, the elastic member 570 is a distorted spring disposed in the base end 531 of the support rod 530. However, as illustrated in the embodiment shown in FIG. 6b, the elastic member 570 is a straight spring extended along the support rod 530.

When the support rod 530 is in the stretched position relative to the base 510, as shown in FIG. 6a and FIG. 7a, the connective stand 550 is connected to the backboard of the second article 700. The base 510 is disposed in a platform to provide a support for the second article 700. Besides, in this situation, the deformable value and the elastic force of the elastic member 570 is the minimum. As shown in FIG. 7b, when the support rod 530 is in the compressing position relative to the base 510, the relative displacement between the support rod 530 and the base 510 is extremely compressed and the volume of the support base 501 is shrunk to the minimum. The deformable value and the elastic force of the elastic member 570 is the maximum. As shown in FIG. 7c, when the support rod 530 is in the less stretching position or less compressing position between the stretching position and the compressing position, the volume of the support base 501 is smaller than the volume where the support base 501 is in the stretching position and larger than the volume where the support base 501 is in the compressing position. The deformable value and the elastic force of the elastic member 570 are increasable. The support rod 530 is rotated relative to the base 510 by the external force, which stretches the elastic member 570 to generate an elastic force relative to the external force for allowing the support base 501 to form a cushion device with shock absorbing structure.

Besides, in order to maintain the support rod 530 in the less stretching position instead of bouncing back to the stretching position, the support base 501 includes a constraining member 590. The constraining member 590 circles around the base 510 and the support rod 530 and limits the support rod 530 to stretch to the stretching position. As shown in FIG. 7c, the constraining member 590 is used to limit the support base 501 to the less stretching position between the stretching position and the compressing position. However, in a different embodiment, the constraining member 590 is used to limit the support base 501 to the extreme compressing position to avoid the support base 501 to have an unpredictable stretching. In the preferred embodiment, the constraining member 590 is a plastic belt. In a different embodiment, the constraining member 590 is a rope or a belt made by different materials. Besides, the constraining member 590 can be replaced by a position device or a clip. In a different embodiment, the constraining member 590 can be used in the first article 500.

As the embodiment shown in FIG. 8a and FIG. 8b, the support base 501 is in the less stretching position between the stretching position and the compressing position and is in the first space 112 of the box 100. The support base 501 is stretched and compressed in the first direction 410. In other words, the connective stand 550 is shifted relative to the base 510 in the first direction by disposing the support rod 530 and the elastic member 570. In the preferred embodiment, the first direction 410 is vertical to the direction of the disposition of the partition 300. The support base 501 is contacting against the partition 300 and provides a force for the partition 300 to absorb the shock and the displacement in the partition 300. In the preferred embodiment, the base 510 of the support base 501 is contacting against the partition 300. Besides, as shown in FIG. 8b, the support base 501 is maintained in the less stretching position by disposing the constraining member 590. However, in a different embodiment, the support base 501 is maintained in the less stretching position by sustaining the weight of the partition 300 and the second article 700.

Besides, in the preferred embodiment, the stretching position, the less stretching position and the compressing position of the second article 700 and the support base 501 are arranged in the first direction 410. As shown in FIG. 8c, when the second article 700 is shaken by an external force, the partition 300 is compressed in the first direction 410. The external force is transmitted from the partition 300 to the support base 501 along the first direction 410. The support base 501 is compressed from the less stretching position and moved to the less compressing position to absorb the shock and the displacement. Because the partition 300 is moved relative to the first cushion 220, the height of the first space 112 is descended from the first height to the second height. At the moment, the elastic member 570 is compressed for storing an elastic strength to force the support base 501 to return from the stretching position to the original position (the less stretching position). By the compression of the support base 501 and the elastic strength of the elastic member 570, the second article 700 is able to reduce the shock generated by the external force and reduce the damage of the second article 700.

As the embodiment shown in FIG. 8a and FIG. 8b, the packing system further includes an elastic material 600. The elastic material 600 is disposed within the first interval 221 between the partition 300 and the first cushion 220. By comparing to the elastic material 600, the partition 300 and the first cushion 220, the rigidity coefficiency of the elastic material 600 is smaller than the rigidity coefficiency of the partition 300 and the first cushion 220. In other words, when the same external force is used, the resistance of the elastic material 600 is less than the resistance of the partition 300 and the first cushion 220. Besides, when the same external force is used, the deformable value of the elastic material 600 is bigger than the deformable value of the partition 300 and the first cushion 220. In the preferred embodiment, the elastic material 600 includes an air pad. However, in a different embodiment, the elastic material 600 includes foam or other materials. As shown in FIG. 8c, when the partition 300 is compressed along the first direction 410, the first interval 221 is reduced to be the second interval 222. Because the rigidity coefficiency of the elastic material 600 is small, the elastic material 600 is compressed and deformed between the partition 300 and the first cushion 220 and operates in coordination with the support base 501 to absorb the shock.

FIG. 9a is another embodiment showing in the present invention. In this embodiment, the support rod 530 of the support base 501 and the base 510 are sleeved together along the axial direction of the support rod 530. In other words, the support rod 530 of the support base 501 and the base 510 are constructed to be a support base structure with telescope type shape. In this embodiment, the elastic member 570 includes a reel spring or a constant force spring. Two ends of the elastic member 570 are respectively connected to the bottom of the support rod 530 and the base 510. The support end 530 is rotatably connected to the connective stand 550. As shown in FIG. 9b, the support base 501 is stored in the first space 112 of the box 100. In this embodiment, the support base 501 includes a constraining member 590 to circle around the connective base 550 of the support base 501 and the base 510 for keeping the support base 501 in the less compressing position. The support base 501 is stretchable and compressible along the first direction 410. In other words, by disposing the support rod 530 and the elastic member 570, the connective stand 550 is shifted relative to the base 510 along the first direction 410. The support base 501 is contacting against the partition 300 and provides a force for the partition 300 to absorb the shock and the displacement of the partition 300. In this preferred embodiment, the connective stand 500 of the support base 501 is contacting against the partition 300. However, in a different embodiment, the base 510 of the support base 501 is contacting against the partition 300.

Besides, in this preferred embodiment, the stretching position, the less compressing position and the compressing position of the second article 700 and the support base 501 are arranged in the first direction 410. When the second article 700 is shaken by an external force, the partition 300 is compressed along the first direction 410. The external force is transmitted from the partition 300 to the support base 501 along the first direction 410. The support base 501 is compressed along the compressing direction to absorb the shaking and the displacement. At the moment, the elastic strength of the elastic member 570 forces the support base 501 to shift back from the compressing position to the original position (the less stretching position). By the compression of the support base 501 and the elastic strength of the elastic member 570, the shock received by the second article 700 from the external force is reduced and the damage of the second article 700 is reduced.

FIG. 10a and FIG. 10b are showing another embodiment of the present invention. As shown in FIG. 10a, the support base 501 is compressed to the compressing position by the weight of the partition 300 and the second article 700. The constraining member 590 is circled around the base 510 and the support rod 530 and limits the stretching of the support base 501 within the less stretching position between the stretching position and the compressing position. In other words, as shown in FIG. 10a, when the support base 501 is compressed to the compressing position, the constraining member 590 is kept in a loose status. When the box 100 is opened, as shown in FIG. 10b, and the partition 300 and the second article 700 are taken out, the support base 501 is bounced back toward the stretching position. By disposing the constraining member 590, the stretching of the support base 501 is limited to the less stretching position for avoiding the support base 501 bouncing back to the stretching position directly.

Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative.
