Summary of the Invention

Problems to be Solved by the Invention

[0005] In order to prevent the luggage from falling during movement, the conventional cage trolley needs to provide a fall prevention bar (see, for example, stay 9 in Patent Document 1) or a door (see, for example, "Security Type" in Non-Patent Document 1) at the opening.

[0006] If there is a fall prevention bar or door, it may get in the way when loading or unloading goods onto the pallet of the cage trolley, reducing work efficiency, and it also requires extra effort to open and close the fall prevention bar or door.

[0007] Furthermore, when luggage is stacked in multiple layers, a structure with a fall prevention bar is insufficient to prevent luggage from falling during transport, while a structure with a door is sufficient to prevent luggage from falling, but it increases manufacturing costs.

[0008] Furthermore, conventional cage trolleys are unsuitable for displaying goods unless the length of the pallet is increased and the width (depth) of the pallet is decreased. However, if the length of the pallet is increased and the width of the pallet is decreased in conventional cage trolleys, the trolley becomes unstable when moved.

[0009] Furthermore, since there is only one configuration for the cage trolley when storing goods on it, the degree of freedom in the configuration when storing goods on the cage trolley is small.

[0010] The present invention aims to provide a linked cage trolley, which consists of two connected cage trolleys, that does not reduce work efficiency when loading and unloading goods from the cage trolley, reliably prevents goods from falling during movement, is suitable for displaying goods, is not unstable during movement, and offers a high degree of freedom in the configuration when storing goods. [Means for solving the problem]

[0011] A connected cage trolley according to a first aspect of the present invention is formed by connecting a first cage trolley and a second cage trolley. The first cage trolley has a first fence body on three sides of a first pallet, and goods are loaded and unloaded from a first opening on one side of the first pallet. The first fence body consists of a first left fence on the left side facing the first opening, a first right fence on the right side, and a first rear fence on the rear side. The second cage trolley has a second fence body on three sides of a second pallet, and goods are loaded and unloaded from a second opening on one side of the second pallet. The second fence body consists of a second left fence on the left side facing the second opening, a second right fence on the right side, and a second rear fence on the rear side. A first vertical rod extending vertically, located on the front side of the first right fence facing the first opening, and a second vertical rod extending vertically, located on the front side of the second left fence facing the second opening, are connected by a pivoting connecting means, allowing for a display configuration in which the first and second cage trolleys are arranged side by side so that the first and second openings are located left and right, and a transport configuration in which the first and second openings face each other, and the front, back, left and right sides of the group of goods stored on the first and second pallets are surrounded by the first and second fences.

[0012] A connected cage trolley according to a second aspect of the present invention is a connected cage trolley according to a first aspect, further comprising a holding means for maintaining the transport configuration.

[0013] A connecting cage trolley according to a third aspect of the present invention is a connecting cage trolley according to a second aspect, wherein the holding means is a connector that connects a third vertical rod extending vertically, located on the front side of the first left fence toward the first opening, and a fourth vertical rod extending vertically, located on the front side of the second right fence toward the second opening. The connector has an elastic engaging portion that elastically engages with the third vertical rod and an elastic engaging portion that elastically engages with the fourth vertical rod, and can be attached to and detached from the third and fourth vertical rods without the use of tools.

[0014] The connected cage trolley according to the fourth aspect of the present invention is a connected cage trolley according to any of the first to third aspects, wherein the length of the first pallet and the length of the second pallet are equal, the width of the first pallet and the width of the second pallet are equal, and the size of the pallet formed by the first pallet and the second pallet in the transport configuration is the standard pallet size of JIS Z 0601. [Effects of the Invention]

[0015] The connected cage trolley according to the present invention consists of a first cage trolley and a second cage trolley connected by a rotating connecting means, and can take the form of a display configuration in which the first cage trolley and the second cage trolley are placed side by side, and a transport configuration in which the front, back and left and right sides of the group of goods placed on the first pallet and the second pallet are surrounded by the first fence and the second fence.

[0016] According to the connected cage trolley of the present invention, since there are no fall prevention bars or doors, work efficiency is not reduced when loading and unloading goods. In the transport configuration, since the front, back, left, and right sides of the group of goods are surrounded by the first and second fences, the goods can be reliably prevented from falling during movement. In the display configuration, since the first opening of the first cage trolley and the second opening of the second cage trolley are located on the left and right sides, the length of the pallet (length of the opening in the left-right direction) is increased, making it suitable for displaying goods.

[0017] When moving in the aforementioned transport configuration, the first and second cage trolleys are folded from the display configuration, and the first and second pallets are adjacent to each other so that the first and second openings face each other, thus preventing instability during transport. Since the two configurations, the display configuration and the transport configuration, can be used as configurations for storing goods on the connected cage trolleys, the degree of freedom in the configuration when storing the goods is greatly increased.

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0020] In this specification, for the first cage cart 1 and the second cage cart 2 constituting the connected cage cart A, the front, rear, left, and right are defined as follows. That is, for the first cage cart 1, the front, rear, left, and right are defined in a state facing the first opening O1 shown in FIGS. 1, 2A, 7, and 9, and for the second cage cart 2, the front, rear, left, and right are defined in a state facing the second opening O2 shown in FIGS. 1, 2A, 7, and 9.

[0021] [Connected Cage Cart] As shown in Figure 1, the connected cage trolley A according to an embodiment of the present invention is formed by connecting a first cage trolley 1 and a second cage trolley 2. For example, four wheels C are attached to the lower surface of the first pallet P1 and the lower surface of the second pallet P2, respectively. All four wheels C may be swivel wheels, or two may be swivel wheels and two may be fixed wheels.

[0022] [First cage trolley] The first cage trolley 1 has a first fence body F1 on three sides of the first pallet P1, and loads are loaded and unloaded from a first opening O1 on one side of the first pallet P1. The first fence body F1 consists of a first left fence 1L on the left side, a first right fence 1R on the right side, and a first rear fence 1B on the rear (front) side, facing the first opening O1.

[0023] [Second cage trolley] The second cage trolley 2 has a second fence body F2 on three sides of the second pallet P2, and loads are loaded and unloaded from a second opening O2 on one side of the second pallet P2. The second fence body F2 consists of a second left fence 2L on the left side, a second right fence 2R on the right side, and a second rear fence 2B on the rear (front) side, facing the second opening O2.

[0024] [Rotating coupling mechanism] A first vertical rod E1, which extends vertically and is located on the front (rear) side of the first right fence 1R facing the first opening O1, and a second vertical rod E2, which extends vertically and is located on the front (rear) side of the second left fence 2L facing the second opening O2, are connected by a general hinge 3, which is a pivoting connecting means H.

[0025] [Display format] Since the connected cage trolley A consists of a first cage trolley 1 and a second cage trolley 2 connected by a rotating connecting means H, it is possible to create a display configuration D in which the first cage trolley 1 and the second cage trolley 2 are arranged side by side, as shown in Figure 2A, with the first opening O1 and the second opening O2 located on the left and right sides.

[0026] As a result, the required cargo B can be placed on the first pallet P1 and the second pallet P2 through the first opening O1 and the second opening O2, and displayed as shown in Figure 2B.

[0027] [Transportation method] Since the connected cage trolley A consists of a first cage trolley 1 and a second cage trolley 2 connected by a rotating connecting means H, the first opening O1 and the second opening O2 shown in Figure 2A can be positioned opposite each other, resulting in the transport configuration T shown in Figure 3A.

[0028] As a result, the display configuration D in Figure 2B changes to the transport configuration T in Figure 3B, and the front, back, left, and right sides of the group of goods G placed on the first pallet P1 and the second pallet P2 are surrounded by the first fence F1 and the second fence F2.

[0029] [Holding means] Figures 3A and 3B show the state in which the holding means M for maintaining the transport configuration T is functioning. Figure 4 shows an example of the holding means M, which consists of a hooking piece 5 and a receiver 6. The hooking piece 5 is rotatably attached to the horizontal rod K2 of the second cage trolley 2 around a pivot shaft 5A, and the receiver 6, which opens upward, is attached to the horizontal rod K1 of the first cage trolley 1. As shown in Figure 4, when the hooking piece 5 is inserted into the receiver 6 from above, the hooking projection 5B protruding from the tip of the hooking piece 5 holds the hooking piece 5 in place on the receiver 6. In this way, the transport configuration T of the connected cage trolley A is maintained by the holding means M.

[0030] [Palette size] As shown in Figure 5, the length L1 of the first pallet P1 and the length L2 of the second pallet P2 are equal (L1=L2). Also, as shown in Figure 5, the width W1 of the first pallet P1 and the width W2 of the second pallet P2 are equal (W1=W2).

[0031] In the transport configuration T of the connected cage trolley A shown in Figure 5, the size of the pallet formed by the first pallet P1 and the second pallet P2, i.e., the length L and width W of the pallet, are the standard pallet size according to JIS Z 0601 (L=1100mm, W=1100mm). Therefore, by using the connected cage trolley A, loading efficiency is increased by eliminating wasted space when loading onto a truck, and storage efficiency and work efficiency are also improved.

[0032] [Modified examples of rotating coupling means and holding means] (Connector) The connector 4 shown in Figure 6 consists of elastic engagement parts 4A and 4B and a connecting part 4C, with the back sides of the openings of the elastic engagement parts 4A and 4B connected by the connecting part 4C. The inner circumferential surfaces N of the elastic engagement parts 4A and 4B are cylindrical surfaces. The connector 4 can be used as a rotating connecting means H or a holding means M.

[0033] When the elastic engaging portions 4A and 4B of the connector 4 are pressed against the vertical rods E1 and E2, etc., their openings are elastically deformed, and then, upon returning to their original state, they engage with the vertical rods E1 and E2, etc. By elastically engaging the elastic engaging portions 4A and 4B with the vertical rods E1 and E2, etc. in this way, the elastic engaging portions 4A and 4B are prevented from coming loose from the vertical rods E1 and E2, etc.

[0034] When the elastic engaging parts 4A and 4B of the connector 4 are pulled away from the connecting part 4C, the elastic engaging parts 4A and 4B elastically deform, causing the vertical rods E1 and E2 to disengage from the elastic engaging parts 4A and 4B. This releases the engagement between the elastic engaging parts 4A and 4B of the connector 4 and the vertical rods E1 and E2.

[0035] As described above, the connector 4 can be attached to and detached from the vertical rods E1, E2, etc., without the use of tools.

[0036] Figure 7-9 shows an example in which the connector 4 is used as both a rotating connecting means H and a holding means M.

[0037] (A connector that is a rotating connecting means) As shown in Figure 7-9, the connecting device 4, which is the rotating connecting means H, elastically engages the elastic engaging portion 4A shown in Figure 6 with the first vertical rod E1, and elastically engages the elastic engaging portion 4B shown in Figure 6 with the second vertical rod E2.

[0038] The outer surfaces of the first vertical rod E1 and the second vertical rod E2 are cylindrical surfaces. Therefore, the inner circumferential surface N (Figure 6) of the cylindrical elastic engagement portion 4A can slide to rotate along the outer surface of the cylindrical first vertical rod E1, and the inner circumferential surface N (Figure 6) of the cylindrical elastic engagement portion 4B can slide to rotate along the outer surface of the cylindrical second vertical rod E2. As a result, the connecting cage trolley A can be configured in the transport configuration T shown in Figure 8 or the display configuration D shown in Figure 9.

[0039] (Connecting device, which is a means of holding) As shown in Figure 7-8, the connecting member 4, which is the holding means M, connects the third vertical rod E3, which extends vertically and is located on the front (rear) side of the first left fence 1L toward the first opening O1, and the fourth vertical rod E4, which extends vertically and is located on the front (rear) side of the second right fence 2R toward the second opening O2.

[0040] In other words, the connecting device 4, which is the holding means M, elastically engages the elastic engaging portion 4A shown in Figure 6 with the third vertical rod E3, and elastically engages the elastic engaging portion 4B shown in Figure 6 with the fourth vertical rod E4. As a result, the transport configuration T can be maintained as shown in Figure 8.

[0041] (Use of connectors as holding devices in display configurations) In the transport configuration T shown in Figure 8, the connecting device 4, which is the holding means M, is attached to the third vertical rod E3 and the fourth vertical rod E4, while in the example shown in Figure 7, the connecting device 4, which is the holding means M, is attached to the fourth vertical rod E4.

[0042] Since the connector 4 can be attached to and detached from the third vertical rod E3 and the fourth vertical rod E4 without the use of tools, the connector 4, which is the holding means M, can be easily removed. Therefore, the connector 4, which has functioned as the holding means M as shown in Figure 8, can be removed, and the connector 4 can be attached to the vertical rods I1 and I2 in the display configuration D shown in Figure 9. Alternatively, the connector 4 may be attached to the vertical rods J1 and J2.

[0043] Thus, in display configuration D, by attaching the connector 4, which functions as a holding means M, to the vertical rods I1, I2 or J1, J2, the display configuration D of the connected cage trolley A can be stably held. Furthermore, in display configuration D shown in Figure 9, since the connector 4 is not attached to the third vertical rod E3 or the fourth vertical rod E4, the appearance of the connected cage trolley A in display configuration D as seen from the openings O1, O2 side is neat and tidy, and the loss of the connector 4 can be prevented.

[0044] [Effects and Effects] The connected cage trolley A according to an embodiment of the present invention consists of a first cage trolley 1 and a second cage trolley 2 connected by a rotating connecting means H, and can take the form of a display configuration D in which the first cage trolley 1 and the second cage trolley 2 are arranged side by side, and a transport configuration T in which the front, back, left and right sides of the group of goods G stored on the first pallet P1 and the second pallet P2 are surrounded by the first fence F1 and the second fence F2.

[0045] According to the connected cage trolley A of the embodiment of the present invention, since there are no fall prevention bars or doors, work efficiency is not reduced when loading and unloading cargo B. In transport configuration T, since the front, back, left, and right sides of the cargo group G are surrounded by the first fence F1 and the second fence F2, the cargo B can be reliably prevented from falling during movement. In display configuration D, since the first opening O1 of the first cage trolley 1 and the second opening O2 of the second cage trolley 2 are located on the left and right sides, the length of the pallet (length of the opening in the left-right direction) is increased, making it suitable for displaying cargo B.

[0046] When moving in transport mode T, the first cage trolley 1 and the second cage trolley 2 are folded from display mode D, and the first pallet 1 and the second pallet 2 are adjacent to each other so that the first opening O1 and the second opening O2 face each other, so that it does not become unstable during movement. Since the two modes, display mode D and transport mode T, can be used as the configuration when storing cargo B on the connected cage trolley A, the degree of freedom in the configuration when storing cargo B is greatly increased.

[0047] All embodiments described above are illustrative and not limiting. Various improvements and modifications can be made without departing from the scope of the present invention. [Explanation of Symbols]
