Description

[Technical Field]

[0001] The present invention relates to a box hanger, and more particularly to a box hanger used to lift a rectangular box. [Background technology]

[0002] Patent Document 1 describes a box hanger used to lift a square box, in which hooks made of U-shaped curved steel plates are attached to the upper ends of each of the opposing walls of the box, and a rope is hung between the two hooks attached to the upper ends of the opposing walls.With the box hanger described in Patent Document 1, the box can be lifted by pushing up the center of the rope from below or pulling it up. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jitszen No. 48-001371 Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, the box hanger described in Patent Document 1 makes it possible to lift a box by hanging a rope between two hooks attached to the upper ends of the opposing walls of the box. However, with the box hanger described in Patent Document 1, when lifting a box, not only an upward force but also a horizontal force acts on the opposing walls via the two hooks from the rope toward the center of the box.

[0005] Therefore, if the rope is too short, the horizontal force will be too great compared to the upward force, causing the box to deform or even break. Therefore, when lifting a heavy object in a box, it is necessary to use a longer rope.

[0006] However, for example, if you tie another rope to the center of the rope connecting the two hooks and pull it up from above, the height of the center of the rope when the box actually starts to move upward will be higher than the position of the top of the box, and there will be some play in the upward distance. Therefore, for example, when lifting one box indoors and stacking it on top of another box, if the rope connecting the two hooks is too long, you will need a considerable amount of clearance in the ceiling height when stacking one box on top of another.

[0007] The present invention was made in consideration of the above-mentioned problems, and its purpose is to provide a box hanger that can lift a box while minimizing the application of horizontal force to the opposing wall of the box, and that can reduce the amount of play in distance when lifting the box upward. [Means for solving the problem]

[0008] The box hanger disclosed herein is used to hoist a box having a pair of engaged portions (2) positioned relative to the opposing walls (1a) of a rectangular box body (1), and comprises a hanger body (10) and a connecting portion (20). The hanger body (10) has a total length (L) longer than the distance between the opposing walls (1a) of the box body (1), has a pair of engaging portions (11, 12) at both ends, and extends linearly. The pair of engaging portions (11, 12) engage with the pair of engaged portions (2) by abutting from below. The connecting portion (20) is attached to approximately the center of the hanger body (10) in the longitudinal direction, and connects the hanger body (10) to an external mechanism (3) that operates to hoist the box.

[0009] In the box hanger disclosed in the present application, the pair of engaged portions (2) are hole-shaped and penetrate the opposing wall (1a), and the pair of engaging portions (11, 12) engage with the pair of engaged portions (2) by being inserted from the inside to the outside of the box body (1) into the pair of engaged portions (2).

[0010] In addition, in the box hanger disclosed in the present application, one (11) of the pair of engaging portions (11, 12) has a rising portion (11a) that rises from the hanger body (10) so as to be able to abut against the peripheral portion of the pair of engaged portions (2) from the outside of the box body (1) when inserted into one of the pair of engaged portions (2).

[0011] The box hanger disclosed herein further comprises a fall-off prevention mechanism (30). The fall-off prevention mechanism (30) is supported on the hanger body (10) so as to be rotatable about a horizontal axis (13) that is oriented intersecting the longitudinal direction of the hanger body (10). When the other (12) of the pair of engaging portions (11, 12) is inserted into the other of the pair of engaged portions (2), the fall-off prevention mechanism (30) engages with the upper end of the box body (1) above the other of the pair of engaged portions (2), thereby preventing the other (12) of the pair of engaging portions (11, 12) from falling off from the other of the pair of engaged portions (2). [Effects of the Invention]

[0012] The box hanger of this invention allows the box to be lifted while minimizing horizontal force on the opposing wall of the box, and also reduces the amount of play in distance when lifting the box upward. [Brief explanation of the drawings]

[0014] The box hanger according to the present invention will be described in detail below with reference to the drawings. The embodiment described below is a preferred example of the present invention, and therefore various technical limitations are imposed. However, the present invention is not limited to this embodiment unless otherwise specified in the following description.

[0015] A box hanger according to an embodiment of the present invention will be described with reference to Figures 1 to 5. Figure 1 is an external perspective view of a box hanger according to an embodiment of the present invention. Figure 2(a) is a front view of the box hanger according to the embodiment. Figure 2(b) is a top view of the box hanger according to the embodiment. Figure 2(c) is a side view of the box hanger according to the embodiment. Figure 3 is an explanatory diagram showing a first method of using the box hanger according to the embodiment. Figure 4(a) is a front view of the retaining mechanism according to the embodiment. Figure 4(b) is a top view of the retaining mechanism according to the embodiment. Figure 5 is an explanatory diagram showing a second method of using the box hanger according to the embodiment.

[0016] As shown in Figures 1 to 3, the box hanger of this embodiment is used to hang a box having a rectangular box body 1, and includes a hanger body 10, a connecting part 20, and a retaining mechanism 30. The rectangular box body 1 has a pair of engaged parts 2 at relative positions on the opposing wall 1a. In this embodiment, the pair of engaged parts 2 are hole-shaped and penetrate the opposing wall 1a.

[0017] The box shown in Fig. 3 is also called a box pallet, and its opposing wall 1a is formed by combining metal round bars. Note that the box to be lifted is not limited to a box pallet, and the opposing wall 1a may be formed from a plate material such as a metal plate, a wooden plate, or plywood.

[0018] When the box to be lifted is a box pallet and the opposing wall 1a is formed by combining metal round bars, a pair of through holes located in relative positions among the many through holes surrounded by the frame of metal round bars is used as a pair of engaged parts 2. When the opposing wall 1a is formed from a plate material, a pair of through holes formed in relative positions on the opposing wall 1a is used as a pair of engaged parts 2.

[0019] In the example shown in Fig. 3, each of the opposing walls 1a has two through holes as engaged portions 2. In this specification, when two or more through holes as engaged portions 2 are formed in one opposing wall 1a, the two or more through holes formed in one opposing wall 1a are treated as one engaged portion 2. Therefore, in the example shown in Fig. 3, a total of four through holes formed in the opposing wall 1a are a pair of engaged portions 2.

[0020] The hanger body 10 has an overall length L that is longer than the distance between the opposing walls 1a of the box body 1, has a pair of engaging portions (11, 12) at both ends, and extends linearly. The pair of engaging portions (11, 12) engage with the pair of engaged portions 2 by abutting from below. In this embodiment, the pair of engaging portions (11, 12) engage with the pair of engaged portions 2 by being inserted into the pair of engaged portions 2 from the inside to the outside of the box body 1.

[0021] The hanger body 10 of the embodiment is formed from two equal-leg angle irons (hereinafter referred to as angles) arranged parallel to each other with a fixed gap between them. The two angles (for example, 50-50 angle irons) each have a first plate 14 and a second plate 15 that intersect at a right angle. The first outer surface 14a of the first plate 14 faces downward, and the second outer surface 15a of the second plate 15 faces sideways so that they face each other. The second plate 15 is joined together by a plurality of cylindrical joining members 16. In the embodiment, the second plate 15 is cut shorter than the first plate 14, so that both ends of the first plate 14 are used as a pair of engaging portions (11, 12).

[0022] Furthermore, the first engaging portion 11, which is one of the pair of engaging portions (11, 12), has a rising portion 11a. When the rising portion 11a is inserted into one of the pair of engaged portions 2, it rises from the hanger body 10 so as to be able to abut against the periphery of one of the pair of engaged portions 2 from the outside of the box body 1. In this embodiment, the rising portion 11a is formed by bending one end of the first plate material 14 into an L-shape. Furthermore, the second engaging portion 12, which is the other of the pair of engaging portions (11, 12), is formed from the other end of the first plate material 14.

[0023] The connecting part 20 is attached to the approximate center of the hanger body 10 in the longitudinal direction, and connects the hanger body 10 to an external mechanism 3 that operates to hoist a box. In this embodiment, a U-shaped curved metal round bar is used as the connecting part 20. The position of the "approximate center" where the connecting part 20 is attached is determined based on the weight balance of the hanger body 10 with the connecting part 20 as a fulcrum.

[0024] More specifically, since it is easier to engage the second engaging portion 12 with the engaged portion 2 before the first engaging portion 11, the attachment position of the connecting portion 20 is set at a weight balance position where the second engaging portion 12 is slightly lower than the first engaging portion 11 when an external mechanism 3 such as a rope is connected to the connecting portion 20.

[0025] Furthermore, a regulating member 17 is provided at an appropriate position near the second engaging portion 12 on the first outer surface 14a. The regulating member 17 protrudes downward from the first outer surface 14a, and comes into contact with the periphery of the engaged portion 2 when the second engaging portion 12 is inserted into the engaged portion 2, thereby regulating the maximum depth to which the second engaging portion 12 can be inserted into the engaged portion 2. By having the regulating member 17 regulate the maximum depth to which the second engaging portion 12 can be inserted into the engaged portion 2, the operation of inserting the second engaging portion 12 into the hole-shaped engaged portion 2 before the first engaging portion 11 and then engaging the first engaging portion 11 with the engaged portion 2 can be facilitated.

[0026] 4 is supported on the hanger body 10 so as to be rotatable about a horizontal axis 13 that is oriented in a direction intersecting with the longitudinal direction of the hanger body 10. In this embodiment, the stop mechanism 30 is formed from two angle pieces (for example, angle pieces of 40-40 size) that are arranged in parallel with a certain distance between them, and has two third plate members 31, two fourth plate members 32, and a connecting member 33.

[0027] The two third plate members 31 are disposed so as to overlap the two first plate members 14 of the hanger body 10, and have protrusions 31a on the surfaces that become the lower sides when overlapping the two first plate members 14. When the second engaging portion 12 is inserted into the engaged portion 2 as shown in FIG. 3 and the retaining mechanism 30 is rotated to the angular position shown by the solid line in FIG. 2, the protrusions 31a engage with the upper end of the box body 1 above the engaged portion 2. By the protrusions 31a engaging with the upper end of the box body 1 above the engaged portion 2, the retaining mechanism 30 can prevent the second engaging portion 12 from falling off the engaged portion 2.

[0028] 4, the two fourth plate members 32 have shaft holes 32a through which the horizontal shafts 13 are inserted, and are disposed so as to sandwich the two second plate members 15 and come into contact with the second plate members 15. The connecting member 33 connects the two angles that form the retaining mechanism 30.

[0029] 2, the tips of the two third plate members 31 of the retaining mechanism 30 protrude beyond the tips of the second engaging portions 12. Therefore, as shown in FIG. 5, when the distance between the opposing walls 1a is longer than the overall length L of the hanger body 10, the two third plate members 31 of the retaining mechanism 30 can be inserted into the engaged portions 2 to lift the box. It is also preferable to form a non-slip surface on the upper surface of the third plate members 31 in preparation for when the two third plate members 31 of the retaining mechanism 30 are inserted into the engaged portions 2 to lift the box.

[0030] As explained above with reference to Figures 1 to 5, according to the box hanger of the embodiment, the hanger body 10 extends linearly, has an overall length L longer than the distance between the opposing walls 1a of the box body 1, has a pair of engaging portions (11, 12) at both ends, and the pair of engaging portions (11, 12) engage with a pair of engaged portions 2 so as to abut from below, and a connecting portion 20 is provided at approximately the center of the length of the hanger body 10, and connects the hanger body 10 to an external mechanism 3 that operates to lift the box. Therefore, the box can be lifted while minimizing the application of horizontal force to the opposing walls 1a, and distance play when lifting the box upward can be reduced.

[0031] As a result of the above, it is possible to suppress horizontal deformation of the opposing wall 1a when lifting a box containing a heavy object, making it possible to lift boxes containing heavier objects than before. Also, for example, when lifting one box and stacking it on top of another indoors, the required ceiling height can be reduced, allowing for greater freedom of movement.

[0032] Furthermore, according to the box hanger of the embodiment, the hanger body 10 is formed from two angles, and the width direction of the second plate material 15 is arranged in the vertical direction, as shown in Figures 2, 3, 5, etc. Therefore, even when a rope or the like is connected to the connecting part 20 attached to the approximate center of the longitudinal direction of the linearly extending hanger body 10 and a box is lifted, the hanger body 10 is less likely to bend, making it easier to lift a box containing a heavier object.

[0033] Furthermore, according to the box hanger of the embodiment, the first engaging portion 11 has a rising portion 11a that rises from the hanger body 10 and can come into contact with the periphery of the engaged portion 2 from the outside of the box body 10. Therefore, it is possible to prevent the second engaging portion 12 from falling off the engaged portion 2, making it possible to lift the box more safely.

[0034] Furthermore, according to the box hanger of the embodiment, the anti-slip mechanism 30 is supported on the hanger body 10 so as to be rotatable around the horizontal shaft 13, and when the second engaging portion 12 is inserted into the engaged portion 2, it engages with the upper end of the box body 1 above the engaged portion 2, preventing the second engaging portion 12 from falling off from the engaged portion 2. Therefore, both the first engaging portion 11 and the second engaging portion 12 can be prevented from falling off from the engaged portion 2, making it possible to lift the box even more safely.

[0035] The embodiments of the present invention have been described above with reference to the drawings (Figs. 1 to 5). However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit and scope of the present invention.
