[Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-144530 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, when moving boxes loaded on a truck bed, one technology for easily moving boxes without using external equipment such as a forklift is a box-moving device that has a roller conveyor that protrudes above the bed using air pressure.

[0006] However, the above-mentioned cargo box moving device has the problem that while the cargo box can be moved on the loading platform, when trying to transfer the cargo to a loading platform outside the vehicle, it is necessary to install additional equipment such as rollers on the loading platform, which is inconvenient.

[0007] To solve the above problems, the present invention aims to provide a box moving device capable of moving a box loaded on a loading platform to another platform without installing additional equipment. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention is configured as follows.

[0009] (1) A cargo box moving device according to the present invention comprises a cargo box to be loaded on a cargo bed, a frame member supporting the bottom side of the cargo box and grounded on the cargo bed side, an airbag arranged between frames constituting the frame member, at least four roller members, and a roller support member supporting the roller members rotatably between the frames, wherein the roller support member supports the roller members so as to be able to select a contact mode in which the roller surface of the roller member is grounded on the cargo bed side and a separation mode in which the roller surface of the roller member is moved away from the cargo bed side, wherein in the separation mode, the roller members are capable of retracting toward the cargo box side beyond the contact surface of the frame member with the cargo bed side, and wherein in the contact mode, the airbag is capable of expanding so as to move the roller surface away from the cargo bed side.

[0010] According to the above configuration, by providing four-wheel roller members stored in a frame member arranged on the bottom surface of the packing box and an airbag as a lift device that can raise and lower the packing box with air pressure, the roller surfaces of the roller members can be brought into contact with the ground in the ground contact mode when moving the packing box. This allows the packing box to be moved manually with a simple configuration, so that the packing box on the loading platform can be safely transferred to another loading platform with a small number of people (for example, one person). As a result, when moving the packing box loaded on the loading platform to another loading platform, the packing box can be moved without installing any additional equipment.

[0011] (2) In the container moving device according to the present invention, it is preferable that the roller support member is configured to be able to select the ground mode and the separation mode by rotating the support shaft of the roller member. With this configuration, the ground mode and the separation mode can be easily switched by rotating the support shaft of the roller member. This makes it possible to efficiently perform the container moving and fixing operations.

[0012] (3) In the box moving device according to the present invention, preferably, the loading platform is provided at the rear of the vehicle, the frame member and the roller member are arranged on the loading platform, and the loading platform can be placed in the separated mode to load the loading platform via the frame member, and the loading platform can be placed in the ground contact mode to ground the roller surface on the loading platform, making the loading platform movable together with the frame member. With this configuration, the loading platform can be easily switched between the ground contact mode and the separated mode on the loading platform of the vehicle. This allows the loading platform to be efficiently moved and fixed.

[0013] (4) In the luggage box moving device according to the present invention, it is preferable that the frame member has a middle portion in the width direction and the depth direction, and the airbag is disposed at a position of the frame member that is out of the middle portion. With this configuration, when the airbag is inflated and the luggage box is lifted off the bed, the posture of the luggage box can be stabilized, and therefore, the luggage box can be prevented from losing its posture and tipping over.

[0014] (5) In the container moving device according to the present invention, it is preferable that the airbag is disposed between adjacent frames of the frame member to the frame member between which the roller members are disposed. With this configuration, interference (e.g., getting caught) between the roller members and the airbag can be prevented.

[0015] (6) The box moving device according to the present invention may preferably be characterized by comprising a storage platform for transporting and storing the box loaded on the platform, and a fixing plate for connecting the storage platform and the platform to fix the platform so that they cannot move relative to each other. With this configuration, the platform and the storage platform can be prevented from moving relative to each other while the box is being moved. This makes it possible to prevent the box from unintentionally falling or tipping over from the platform or the storage platform.

[0016] (7) In this case, it is preferable that the storage platform is provided with a height adjustment unit for adjusting the height of the storage platform to the height of the loading platform. With this configuration, the height of the storage platform can be easily adjusted to match the height of the loading platform by adjusting the height adjustment unit, so that the loading box can be moved smoothly between the loading platform and the storage platform.

[0017] (8) In the above-mentioned storage platform and the box moving device having the fixing plate, the platform is preferably provided on a vehicle capable of loading the box, a flap portion that can be opened and closed relative to the platform is provided at the widthwise end of the platform, one end of the fixing plate is fixed to the storage platform, and the other end of the fixing plate is fixed to the platform so as not to move relative to the platform by being inserted into a gap between the platform and the flap portion when the flap portion is in an open state. With this configuration, the platform and the storage platform can be prevented from moving relative to each other while the box is moving. Therefore, the box can be prevented from unintentionally falling or tipping from the platform or the storage platform. Furthermore, since the other end of the fixing plate can be inserted and fixed using the gap between the platform and the flap portion, there is no need to prepare a separate member for fixing the other end of the fixing plate.

[0018] (9) The container box moving device according to the present invention may preferably be characterized by comprising a storage platform for transporting and storing the container boxes loaded on the container platform, and rail members connecting the container platform and the storage platform so as to enable the movement of the roller members of the container boxes. With this configuration, the container boxes can be easily moved between the container platform and the storage platform by moving the roller members along the rail members.

[0019] (10) In this case, it is preferable that a movement restriction portion for restricting the movement of the roller member of the packing box is provided on the upper surface of the storage platform. With this configuration, when the packing box is moved from the platform to the storage platform, the packing box can be stopped at a predetermined location on the storage platform. This makes it possible to prevent the packing box from unintentionally falling off the storage platform.

[0020] (11) In the above-mentioned box moving device including the storage platform and rail member, the loading platform is preferably provided on a vehicle capable of loading the loading platform, a flap portion that can be opened and closed relative to the loading platform is provided at the widthwise end of the loading platform, a magnet is attached to the rail member, and the rail member is attached to the flap portion by the magnetic force of the magnet.

[0027] (packing box) The packing box 10 is a box capable of storing luggage. The packing box 10 has a rectangular parallelepiped appearance, but the shape and material of the packing box 10 are not particularly important as long as the box can store luggage.

[0028] (Frame member) The frame member 20 has a support surface 22 and a ground surface 24. The support surface 22 is a surface that supports the bottom surface 12 of the packing box 10. The ground surface 24 is a surface that comes into contact with the upper surface 212 of the loading platform 210. As shown in FIG. 2, the frame member 20 has an outer frame formed in a rectangular shape. The frame member 20 is also formed in a lattice shape overall, and has a plurality of gaps (S1, S21, S22, S3, S4, S5, and S6). A gap (middle part) S1 is provided at approximately the center of the width direction and depth direction of the frame member 20. Here, the width direction refers to the direction in which the roller support member 50 extends, and the depth direction refers to the direction perpendicular to the direction in which the roller support member 50 extends.

[0029] In addition, in the width direction of the intermediate portion S1, a frame interval S21 having a larger interval in the width direction than the intermediate portion S1 is provided. In the depth direction of the intermediate portion S1, a frame interval S22 having a smaller interval in the depth direction than the intermediate portion S1 is provided. In addition, in the width direction of the frame interval S22, a frame interval S3 having a larger interval in the width direction than the frame interval S22 is provided. Outside the frame interval S22 in the depth direction, a frame interval S4 having a smaller interval in the depth direction than the frame interval S22 is provided. Outside the frame interval S3 in the depth direction, a frame interval S5 and a frame interval S6 having a smaller interval in the depth direction and width direction than the frame interval S3 are provided. The frame intervals S4, S5, and S6 have the same size in the depth direction, and the size in the width direction of the frame interval S4 is larger than the frame interval S5, and the frame interval S5 is larger than the frame interval S6. Note that the configuration of the frame member 20 described above is merely an example of the present invention, and is not limited to that shown in this embodiment as long as it does not deviate from the spirit of the present invention. For example, the width, number, size, and other factors of the frames that constitute the frame member 20 are not limited to those described above, and various other combinations are possible.

[0030] (Airbag) A plurality of airbags 30 (four in this embodiment) are arranged in the frame gap S3 constituting the frame member 20. These airbags 30 are arranged near the edges of the frame member 20 and near and inside the roller members 40. In other words, the airbags 30 are arranged at positions outside the middle portion S1 of the frame member 20. The airbags 30 are arranged in other frame gaps S3 adjacent to the frame gap S6 in which the roller members 40 of the frame member 20 are arranged.

[0031] An air inlet 32 ​​(see FIG. 5) for injecting air is connected to the airbag 30. Air is injected into the airbag 30 from a rechargeable air pump 60 (air pump unit) composed of an air compressor, a battery, etc., through a tube 62 and the air inlet 32. The rechargeable air pump 60 (air pump unit) is stored in the cargo box 10 and can be taken out when necessary. In this embodiment, the air inlet 32 ​​is arranged so as to face the width direction of the vehicle 200 when the cargo box 10 is loaded on the cargo bed 210. As shown in FIG. 6, by injecting air into the airbag 30, the cargo box 10 can be floated at a predetermined height above the cargo bed 210.

[0032] (Roller member, roller support member) A plurality of roller members 40 (four in this embodiment) are arranged in the frame space S6 that constitutes the frame member 20. The roller support member 50 rotatably supports the roller members 40 in the frame space S6. The roller support member 50 is a shaft-shaped member, and a plurality of roller support members 50 (two in this embodiment) are provided so as to penetrate the frame spaces S4, S5, and S6 that constitute the frame member 20. As shown in FIG. 3, the roller members 40 are rotatably held relative to the roller support members 50 by a holding member 44.

[0033] Moreover, two roller members 40 are supported by one roller support member 50. The two roller support members 50 are arranged parallel to each other. The roller support member 50 is arranged so as to extend in the width direction of the vehicle 200 when the packing box 10 is loaded on the loading platform 210.

[0034] A knob portion 52 is provided at one end of the roller support member 50. The roller member 40 rotates by pulling and rotating the knob portion 52 in the axial direction (width direction in FIG. 2). In this embodiment, the state in which the roller member 40 stands on the platform 210 (movable state) as shown in FIG. 3 is referred to as the "ground contact mode," and the state in which the roller member 40 lies on the platform 210 (immovable state) as shown in FIG. 4 is referred to as the "detached mode."

[0035] In other words, the roller support member 50 supports the roller member 40 so that a contact mode in which the roller surface 42 of the roller member 40 is grounded against the loading platform 210 and a separation mode in which the roller surface 42 of the roller member 40 is separated from the loading platform 210 can be selected.

[0036] In addition, in the separation mode, the roller members 40 can be retracted toward the container 10 side from the contact surface 24 of the frame member 20 with the container platform 210. In addition, by switching to the separation mode on the container platform 210, the container platform 10 can be placed on the container platform 210 via the frame member 20.

[0037] Moreover, by placing the roller surface 42 of the roller member 40 on the loading platform 210 in the ground contact mode, the loading box 10 can be made movable together with the frame member 20. Moreover, in the ground contact mode, the airbag 30 can be expanded so as to move the roller surface 42 of the roller member 40 away from the loading platform 210.

[0038] (Storage stand) 8 to 13, the storage platform 300 is for transporting and storing the packing boxes 10 loaded on the loading platform 210, and has an overall box shape. The storage platform 300 also includes four height adjustment units 310, a movement restriction unit 320, and four casters 330.

[0039] The height adjustment unit 310 is provided at the bottom of the storage table 300. The height adjustment unit 310 is for adjusting the height of the upper surface 302 of the storage table 300 relative to the height of the upper surface 212 of the loading platform 210. The height adjustment unit 310 is composed of casters (wheels) 330 and the like, and the height adjustment can be performed by the casters 330 to align the height with the upper surface 212 of the loading platform 210. The movement restriction unit 320 restricts the movement of the roller member 40 of the packing box 10. The movement restriction unit 320 is provided on the upper surface 302 of the storage table 300 so as to protrude upward. It is preferable that the movement restriction unit 320 can be freely installed (adjusted) at any position on the upper surface 302 of the storage table 300 by a magnet or the like for ease of use.

[0040] (Fixed plate) The fixing plate 400 is for connecting and fixing the storage platform 300 and the loading platform 210 to each other. The fixing plate 400 is provided at two locations between the storage platform 300 and the loading platform 210. The fixing plate 400 includes a first plate portion 410, a second plate portion 420, and a connection portion 430.

[0041] One end of the first plate portion 410 of the fixed plate 400 is fixed to the end of the upper surface 302 of the storage platform 300 on the loading platform side. One end of the second plate portion 420 of the fixed plate 400 is fixed by being inserted into a gap between the loading platform 210 and the flap portion 220 when the flap portion 220 is in the open state. The other end of the first plate portion 410 and the other end of the second plate portion 420 are connected at a connecting portion 430 so as to be rotatable. By folding the first plate portion 410 and the second plate portion 420 at the connecting portion 430, the fixed plate 400 can be stored compactly.

[0042] (Rail parts) The rail member 500 is for moving the packing box 10 on the loading platform 210 to the storage platform 300. The rail member 500 is mainly made of metal, but the material is not particularly limited as long as the packing box 10 can be moved. The rail member 500 is bridged between the loading platform 210 and the storage platform 300. The length of the rail member 500 is a length that allows the roller members 40 of the packing box 10 to contact the ground and connect the loading platform 210 and the storage platform 300 when the packing box 10 is loaded on the loading platform 210 of the vehicle 200.

[0043] A magnet is attached to one surface of the rail member 500. The rail member 500 to which the magnet is attached is attached by the magnetic force of the magnet to the inner surface of the tailgate 220 of the vehicle 200 and stored. The other surface of the rail member 500 is adapted to be moved by contact with the roller surface 42 of the roller member 40 of the loading platform 210.

[0044] Next, a procedure for moving a packing box 10 using the packing box moving device 100 according to this embodiment will be described with reference to FIGS.

[0045] First, as shown in Fig. 1, before the cargo box 10 is moved, the cargo box 10 is loaded on the cargo bed 210 of the vehicle 200. Next, as shown in Fig. 5, the cargo box 10 and the rechargeable air pump 60 are connected by a tube 62. The rechargeable air pump 60 is stored inside the cargo box 10 and can be taken out when necessary.

[0046] 6, the switch of the rechargeable air pump 60 is turned on, and air is injected into the airbags 30. This causes the four airbags 30 provided at the bottom of the cargo box 10 to inflate (expand), and the cargo box 10 is lifted upward from the cargo bed 210.

[0047] Next, as shown in Fig. 7, when the knob portion 52 of the roller support member 50 is pulled and rotated clockwise, the roller members 40 (casters) rotate to an upright state, and the device is placed in the ground contact mode (see Fig. 3). Note that by rotating one roller support member 50, two roller members 40 rotate to an upright state. At this time, the roller surfaces 42 of the roller members 40 are raised above the loading platform 210.

[0048] Next, as shown in Fig. 8, the storage platform 300 is connected to the vehicle 200. The height adjustment parts 310 (casters 330) of the storage platform 300 are adjusted in advance so that the upper surface 302 of the storage platform 300 is adjusted to the same height as the upper surface 212 of the loading platform 210. The storage platform 300 is then moved to the position of the tailgate 220, and the two fixing plates 400 are inserted into the gap between the loading platform 210 and the tailgate 220.

[0049] Next, as shown in Fig. 9, a rail member 500 (caster rail) is installed to bridge the loading platform 210 and the storage platform 300. The rail member 500, which was attached to the inside of the side panel 220 with a magnet, is removed and installed in a predetermined position on the upper surface 212 of the loading platform 210 to serve as a bridge. A magnet (magnetic sheet) is provided on the back surface of the rail member 500, and the large surface area provides a high adhesive force (magnetic force).

[0050] 10, the shipping box 10 is lowered so that the roller surface 42 of the roller member 40 is brought into contact with the rail member 500. At this time, the air is released from the airbag 30 using the air release function of the compressor in the rechargeable air pump 60, and the roller surface 42 of the roller member 40 of the shipping box 10 is brought into contact with the rail member 500.

[0051] 11, the packing box 10 is pushed by hand from the loading platform 210 to the storage platform 300. By making the roller members 40 of the packing box 10 fixed, it is possible to facilitate straight-line movement.

[0052] 12, the packing box 10 is run toward the storage table 300 and moved to the movement restriction portion 320 (stopper position) on the upper surface 302 of the storage table 300. That is, the packing box 10 is moved and stopped at a position where the roller member 40 abuts against the movement restriction portion 320 (stopper).

[0053] Finally, as shown in Fig. 13, after the movement is completed, the switch of the rechargeable air pump 60 is turned on, air is injected into the airbag 30, and the cargo box 10 is lifted upward from the storage stand 300. When the knob portion 52 of the roller support member 50 is turned counterclockwise, the roller member 40 rotates to a lying position and enters the separation mode (see Fig. 4). The air vent function of the rechargeable air pump 60 is used to lower the cargo box 10 and secure it to the storage stand 300. The fixing plate 400 clamped to the tailgate 220 of the vehicle 200 is removed, and the storage stand 300 is moved. With the above procedure, the movement of the cargo box 10 is completed.

[0054] According to the embodiment described above, the following advantages (1) to (11) can be obtained.

[0055] (1) In the above embodiment of the cargo box moving device 100, in the separation mode, the roller member 40 can be moved toward the cargo box 10 from the contact surface 24 of the frame member 20, and in the contact mode, the airbag 30 can be expanded so as to separate the roller surface 42 of the roller member 40 from the upper surface 212 of the cargo bed 210.

[0056] According to the above embodiment, by providing the four-wheel roller members 40 housed in the frame member 20 arranged on the bottom surface 12 of the packing box 10 and the airbag 30 as a lift device capable of raising and lowering the packing box 10 by air pressure, when moving the packing box 10, the roller surface 42 of the roller members 40 can be grounded on the upper surface 212 of the loading platform 210 in the ground contact mode. This allows the packing box 10 to be moved manually with a simple configuration, so that the packing box 10 on the loading platform 210 can be safely transferred to the storage platform 300 by a small number of people (for example, one person). As a result, when moving the packing box 10 loaded on the loading platform 210 to the storage platform 300, the packing box 10 can be moved without installing any additional equipment.

[0057] (2) In the container moving device 100 according to the above embodiment, the roller support member 50 is rotated to select between the ground contact mode and the separation mode of the roller member 40. This allows the roller member 40 to be easily switched between the ground contact mode and the separation mode by rotating the roller support member 50. This allows the container 10 to be moved and fixed efficiently.

[0058] (3) In the above embodiment, the packing box moving device 100 can be placed on the loading platform 210 of the vehicle 200 via the frame member 20 by switching to the separation mode on the loading platform 210, and can be placed in a movable state together with the frame member 20 by switching to the ground contact mode on the loading platform 210 and grounding the roller surfaces 42 of the roller members 40 on the loading platform 210. This allows the packing box 10 to be easily switched between the ground contact mode and the separation mode on the loading platform 210 of the vehicle 200. This allows the packing box 10 to be moved and fixed efficiently on the loading platform 210 of the vehicle 200.

[0059] (4) In the cargo box moving device 100 according to the above embodiment, the airbag 30 is disposed at a position that is out of the middle portion S1 of the frame member 20. As a result, when the airbag 30 is inflated and the cargo box 10 is lifted off the loading platform 210, the posture of the cargo box 10 can be stabilized, and therefore, the cargo box 10 can be prevented from losing its posture and tipping over.

[0060] (5) In the box moving device 100 according to the above embodiment, the airbag 30 is disposed in the space S3 adjacent to the space S6 in which the roller members 40 are disposed in the frame member 20. This makes it possible to prevent interference (e.g., jamming) between the roller members 40 and the airbag 30.

[0061] (6) In the above embodiment of the packing box moving device 100, the storage platform 300 and the loading platform 210 are fixed to be immovable relative to each other by being connected by the fixing plate 400. This makes it possible to prevent the loading platform 210 and the storage platform 300 from moving relative to each other while the packing box 10 is being moved. This makes it possible to prevent the packing box 10 from unintentionally falling or tipping over from the loading platform 210 or the storage platform 300.

[0062] (7) In the packing box moving device 100 according to the above embodiment, the height adjustment unit 310 of the storage platform 300 makes it possible to adjust the height of the upper surface 302 of the storage platform 300 relative to the height of the upper surface 212 of the loading platform 210.

[0063] (8) In the above embodiment of the container box moving device 100, the second plate portion 420 of the fixed plate 400 is inserted into the gap between the container platform 210 and the flap portion 220 when the flap portion 220 is in the open state, thereby fixing the container platform 210 so as not to move relative to the container platform 210. This makes it possible to prevent the container platform 210 and the storage platform 300 from moving relatively while the container platform 210 is moving. This makes it possible to prevent the container platform 10 from unintentionally dropping or tipping over from the container platform 210 or the storage platform 300. Furthermore, since the second plate portion 420 of the fixed plate 400 can be inserted and fixed using the gap between the container platform 210 and the flap portion 220, there is no need to prepare a separate member for fixing the second plate portion 420 of the fixed plate 400.

[0064] (9) In the above embodiment, the container box moving device 100 transports and stores the container boxes 10 loaded on the container platform 210 by the storage platform 300, and the container platform 210 and the storage platform 300 are connected so that the roller members 40 of the container boxes 10 can be moved by the rail members 500. This allows the container boxes 10 to be easily moved between the container platform 210 and the storage platform 300 by moving the roller members 40 along the rail members 500.

[0065] (10) In the packing box moving device 100 according to the above embodiment, a movement restricting portion 320 is provided on the upper surface 302 of the storage stand 300 to restrict the movement of the roller member 40 of the packing box 10. This allows the packing box 10 to be stopped at a predetermined location on the storage stand 300 when the packing box 10 is moved from the loading platform 210 to the storage stand 300. This makes it possible to prevent the packing box 10 from unintentionally falling off the storage stand 300.

[0066] (11) In the cargo box moving device 100 according to the above embodiment, the rail member 500 can be attached to the gate section 220 by the magnetic force of a magnet. Thus, by attaching the rail member 500 to the gate section 220, the rail member 500 can be stored so as not to move while the vehicle is moving. This allows the rail member 500 to be stored safely and compactly.

[0067] (Modification) The above embodiment can be modified as follows.

[0068] In the above embodiment, a loading platform provided at the rear of a vehicle is shown as an example of a loading platform, but the present invention is not limited to this. In the present invention, a loading platform other than a loading platform of a vehicle may be used as long as it is capable of loading (placing) a cargo box thereon.

[0069] In the above embodiment, four airbags are arranged in the frame member, but the present invention is not limited to this. In the present invention, the number of airbags may be appropriately changed depending on the size and weight of the cargo box.

[0070] In the above embodiment, four roller members are arranged on the frame member, but the present invention is not limited to this. In the present invention, five or more roller members may be provided depending on the size and weight of the packing box.

[0071] In the above embodiment, an example has been shown in which the roller member is provided outside the airbag between the frames of the frame members, but the present invention is not limited to this. In the present invention, the roller member may be provided inside the airbag between the frames of the frame members. Also, while an example has been shown in which the airbag and the roller member are disposed adjacent to each other between the frames of the frame members, the airbag and the roller member may be disposed at a predetermined interval.

[0072] In the above embodiment, an example in which a rectangular airbag is provided has been shown, but the present invention is not limited to this. In the present invention, the shape of the airbag may be appropriately changed to match the shape of the gap between the frame members.

[0073] In the above embodiment, the frame member directly supports the packing box, but the present invention is not limited to this. In the present invention, a separate member may be provided between the frame member and the packing box.

[0074] The above-described embodiments are merely examples of the application of the present invention, and it goes without saying that any other embodiments within the scope of the claims are also included in the technical scope of the invention. [Explanation of symbols]
