Description

Technical Field

[0001] This application relates to corner guards.

Background Art

[0002] When moving or transporting heavy loads such as machines, devices, materials, etc., by hanging them with belts or strings, protective devices such as corner guards are attached to the corner portions of the loads, and the belts or strings are passed over the loads via the corner guards. Such corner guards, in addition to those disclosed in Citation 1, are being put into practical use in various forms.

[0003] However, when a belt or string is passed over a corner guard, the belt and string may shift on the corner guard. Also, corner guards made of elastic materials such as urethane or corner guards with cushioning materials such as sponges attached to the surfaces contacting the loads are known in order to reduce the load on the loads, but they are liable to deteriorate over time. Therefore, it is also conceivable to manufacture corner guards from materials with higher rigidity than urethane or sponge, but corner guards that are merely placed against the corners of the loads for passing belts and strings are likely to fall, and may crack or break when they fall.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In consideration of the above problems, an object of the present invention is to provide a corner guard that ensures strength and improves stability.

Means for Solving the Problems

[0006] One aspect of the present disclosure is a corner guard used as a corner protector when transporting columnar cargo, on which a belt or strap can be stretched, comprising at least one unit, the corner portion having a top surface portion whose inner side abuts against the top surface of the cargo, a side portion continuous with the top surface portion along the length direction and abutting against the side surface of the cargo on the inside, a corner portion connecting the top surface portion and the side portion, the corner portion having a corner protrusion on the outside, and guide portions formed along the length direction at both ends in the width direction of the top surface portion and the side portion.

[0007] Furthermore, according to one aspect of this disclosure, two or more units may be connected in the width direction and formed as a single unit.

[0008] Furthermore, according to one aspect of the present disclosure, three units may be integrally formed by connecting them in the width direction, and holes may be formed through the top and / or side surfaces of the units.

[0009] Furthermore, according to one aspect of this disclosure, the first contact surface of the top portion that abuts the top surface of the package and the second contact surface of the side portion that abuts the side surface of the package may be configured to form an angle between 90 degrees and 110 degrees.

[0010] Furthermore, according to one aspect of the present disclosure, the corner portion may have a rib extending from the top surface to the side surface in the portion that contacts the corner of the inner load.

[0011] Furthermore, according to one aspect of this disclosure, cushioning members may be attached to the portion of the top surface that contacts the top surface of the luggage and to the portion of the side surface that contacts the side surface of the luggage.

[0012] Furthermore, according to one aspect of the present disclosure, the guide portion may have a convex portion that protrudes outward and a concave portion adjacent to the convex portion that is recessed inward.

[0013] Furthermore, according to one aspect of this disclosure, the top surface may have a first raised portion formed in a continuous manner with the corner raised portion, and the side surface may have a second raised portion formed in a continuous manner with the corner raised portion, and the second raised portion may be formed to have a greater weight than the first raised portion. [Effects of the Invention]

[0014] According to the corner guard of this disclosure, when the corner guard is placed on the corner of a load, the inner surface of the top portion abuts against the top surface of the load, and the inner surface of the side portion abuts against the side of the load. Therefore, the corner guard can be stably placed on the corner of the load before a belt or strap is attached. In addition, a corner portion is formed at the part connecting the top portion and the side portion of the corner guard, and the corner portion has a corner ridge on the outside. Therefore, the corner portion connecting the top portion and the side portion can be reinforced, and the overall strength of the corner guard can be improved. Furthermore, when a belt or strap is attached, the corner ridge can concentrate the support of the belt or strap, so that the load acts directly on the corner of the load, and the corner guard with the belt or strap attached can be stabilized. In addition, after stabilizing the corner guard, the load on the load from the top portion and side portion can be reduced. Furthermore, the corner guard is provided with guide portions formed along the length direction at both ends in the width direction of the top portion and side portion. Therefore, when lifting a load, the widthwise sliding of the belt or strap stretched across the corner guard can be restricted, thereby stabilizing both the corner guard and the load.

[0015] Furthermore, according to the corner guard of this disclosure, two or more units comprising a top surface, side surface, corner section, and guide section can be connected in the width direction to form an integral structure. Therefore, by using a single corner guard made up of multiple integrally formed units for the corners of large loads, the load can be lifted using multiple belts or ropes. This allows the load to be lifted stably.

[0016] Furthermore, according to the corner guard of this disclosure, holes are formed through the top and / or side surfaces of the corner guard, which is integrally formed by connecting three units in the width direction. Therefore, a user who intends to place the corner guard on the corner of a package can insert their hand into the hole in the corner guard and grasp it, making it easy to attach the corner guard to the package and allowing it to be stably attached to the package.

[0017] Furthermore, according to the corner guard of this disclosure, the first contact surface of the top portion that abuts the top surface of the luggage and the second contact surface of the side portion that abuts the side of the luggage are configured to form an angle between 90 and 110 degrees. Therefore, the corner guard can be fitted to the corner of the luggage and attached stably.

[0018] Furthermore, according to the corner guard of this disclosure, the corner portion may be provided with a rib extending from the top surface to the side surface at the portion that contacts the inner corner of the load. This improves the strength of the corner portion, which contacts the corner of the load and is subjected to a larger load than other parts.

[0019] Furthermore, according to the corner guard of this disclosure, cushioning members can be attached to the portion of the top surface that contacts the top surface of the load and the portion of the side surface that contacts the side surface of the load. Therefore, when the load is lifted, the load on the load from the top surface and side surface can be mitigated by the cushioning members.

[0020] Furthermore, according to the corner guard of this disclosure, the guide portion may include a convex portion that protrudes outward and a recess adjacent to the convex portion that is recessed inward. Therefore, when a belt or string is stretched across the width direction of the unit, the belt or string can be placed in the recess, and the adjacent convex portion can restrict the sliding of the belt or string. This allows the belt or string to be stably stretched across the width direction of the corner guard as well.

[0021] Moreover, according to the corner guard related to the present disclosure, it has a first raised portion continuously formed on the side of the top surface portion and continuous with the corner raised portion, and a second raised portion continuously formed on the side of the side surface portion and continuous with the corner raised portion. The second raised portion can be formed to be heavier than the first raised portion. Therefore, when lifting a load with a belt or string passed over it, the belt or string comes into contact over a wide range, and the strength of the side surface portion where the load acts can be improved. Also, the downward gravity along the side surface of the load when the corner guard is arranged at the corner of the load can be increased, and the top surface portion and thus the corner guard can be more stably arranged at the corner of the load.

Embodiments for Carrying out the Invention

[0023] Hereinafter, the corner guard according to the embodiment will be described with reference to the accompanying drawings. The same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted. For ease of understanding, the scale of the drawings may be changed for the description.

[0024] Figures 1 and 2 show perspective views of a corner guard 10, as an example, which is positioned as a so-called corner protector at the corner where the top and side surfaces of luggage CA connect, with a belt BT stretched across it. Here, the corner guard 10 is integrally formed by connecting a first unit 12, a second unit 14, and a third unit 16 in the width direction. Here, the corner guard 10 is described as having three units 12, 14, and 16, but it is not limited to this, and the corner guard may be constructed by integrally forming one, two, or four or more units as described below, according to the dimensions of the luggage. Alternatively, the corner guard may be integrally formed by connecting multiple units according to the weight of the luggage, rather than the dimensions, and multiple belts or straps may be stretched across it.

[0025] The corner guard 10 is made of resin in this description. However, the corner guard only needs to ensure a certain level of strength and may be made of other materials, such as synthetic wood, metal, or other materials. The three units 12, 14, and 16 that make up the corner guard 10 are constructed with the same specifications except for the hole 36 described below. Therefore, this description will mainly use the second unit 14, which is located in the center of the width direction of the three units 12, 14, and 16.

[0026] Each unit 12, 14, and 16 comprises a top portion 18 whose inner side abuts against the top surface TF of the luggage CA, and a side portion 20 that is continuous with the top portion 18 along the length direction through which a belt BT or string (not shown) is stretched, and whose inner side abuts against the side surface SF of the luggage CA. A corner portion 22 is formed at the portion connecting the top portion 18 and the side portion 20, i.e., the portion facing the corner of the luggage CA.

[0027] The corner section 22 has a corner raised section 24 that is formed to protrude outward, away from the load CA. As a result, the corner section 22 can have higher rigidity than other parts of each unit 12, 14, and 16. This reinforces the corner section 22 that connects the top surface 18 and the side surface 20, and improves the overall strength of the corner guard 10. In addition, because the corner raised section 24 is more raised than the top surface 18 and the side surface 20, the belt BT makes strong contact when the load CA is lifted by placing the belt BT across it. As a result, the weight of the load CA, i.e., the load, can be concentrated at the corner raised section 24, and the load acts directly on the corner of the load CA, thus stabilizing the corner guard 10 and the load CA.

[0028] At both ends in the width direction of each unit 12, 14, and 16, guide portions 30 are formed that protrude outward from the top surface 18 and the side surface 20, extending along the entire length from the top surface 18 to the side surface 20. The guide portions 30 have alternatingly formed convex portions 32 and concave portions 34 along the length direction of each unit 12, 14, and 16. At the ends of the top surface 18 and the side surface 20 opposite to the corner portions 22, convex portions 32 are formed that protrude outward from the concave portions 34. Furthermore, concave portions 34 are formed continuously with, i.e., adjacent to, the convex portions 32 and recessed inward from the convex portions 32. Therefore, when a belt BT is stretched along the length direction of each unit 12, 14, and 16, the sliding of the belt BT in the width direction is restricted, stabilizing the stretched belt BT and the lifted load CA.

[0029] The guide section 30 also allows the belt BT to be positioned in the recess 34 when the belt BT is stretched across each unit 12, 14, and 16 along their width. This allows the adjacent protrusions 32 to restrict the belt BT from sliding along the length of each unit 12, 14, and 16, and allows the belt BT or strap to be stably stretched across the width of the corner guard 10.

[0030] Figure 3 shows a perspective view of the corner guard 10 alone, seen from the outside. Here, holes 36 are formed through the top surface 18 and side surface 20 of the second unit 14. The holes 36 are sized so that a user of the corner guard 10 can insert their hand and grasp it. Therefore, a user who intends to place the corner guard 10 on the corner of the luggage CA can put their hand through the hole 36 of the corner guard 10 and grasp it. This makes it easy to attach the corner guard 10 to the luggage CA and allows the corner guard 10 to be stably attached to the luggage CA. Here, the holes 36 are described as being formed on the top surface 18 and side surface 20 of the second unit 14, but this is not limited to this, and the holes may be formed on only one of the top surface or side surface, or the holes may be formed on units other than the central part.

[0031] Furthermore, the corner guard 10 is configured such that the first contact surface 38 of the top surface portion 18 that abuts against the top surface TF of the luggage CA (see Figure 4) and the second contact surface 40 of the side surface portion 20 that abuts against the side surface SF of the luggage CA (see Figure 4) form an angle AG between 90 and 110 degrees. Here, the angle AG is set to approximately 90 degrees. As a result, the corner guard 10 can be fitted to the corner of the luggage CA and can be stably attached to the luggage CA.

[0032] Furthermore, the corner guard 10 has a first raised portion 26 formed on the top surface 18 side in a portion continuous with the corner raised portion 24, and a second raised portion 28 formed on the side surface 20 side in a portion continuous with the corner raised portion 24. The second raised portion 28 is formed to be heavier than the first raised portion 26 by either raising it outward more than the first raised portion 26, or by using a material with a higher density than the first raised portion 26. Therefore, when a load with a belt BT stretched over it is lifted, the belt BT makes contact over a wide area, and the strength of the side surface 20 where the load is applied can be ensured. In addition, when the corner guard 10 is placed at the corner of the load CA, the downward force of gravity along the side of the load CA can be increased, and the top surface 18 and, consequently the corner guard 10 can be placed at the corner of the load CA more stably.

[0033] Figure 4 shows a perspective view of the corner guard 10 from the inside. A rib 42 is formed on the inner portion of the corner 22, extending along the length of the corner guard 10 from the top surface 18 to the side surface 20. Therefore, the corner guard 10 can be positioned so that the rib 42 abuts against the corner of the load CA, thereby improving the strength of the corner 22, which is subjected to a larger load than other parts when the load CA is lifted. The length, height, and number of ribs may be increased or decreased depending on the intended use.

[0034] Furthermore, the corner guard 10 has a first contact surface 38 that abuts the top surface TF of the luggage CA on the top surface 18 and a second contact surface 40 that abuts the side surface SF of the luggage CA on the side surface 20, with a first cushioning member 44 and a second cushioning member 46 attached to them, respectively. As a result, the corner guard 10 abuts the top surface TF and the side surface SF via these cushioning members 44 and 46. The first cushioning member 44 and the second cushioning member 46 are made of an elastic material such as rubber, and when the luggage CA is lifted, the load on the luggage CA from the top surface 18 and the side surface 20 can be alleviated.

[0035] (modified version) Figure 5 shows a modified example of a corner guard 10 formed solely from the first unit 12. As described above, the corner guard 10 can be formed not only by connecting the three units 12, 14, and 16, but also by using a single unit 12 independently. This allows for stable lifting of cargo CA, even if its width or thickness is smaller than other parts, such as a door or window frame, by placing the corner guard 10 at the corner of the cargo CA.

[0036] Next, the operation and effects of the corner guard 10 according to this embodiment will be explained.

[0037] According to the corner guard 10 of this embodiment, when the corner guard 10 is placed on the corner of the luggage CA, the rib 42 formed on the inside of the top surface 18 abuts against the corner of the luggage CA. In addition, the first contact surface 38 abuts against the top surface TF of the luggage CA via the first cushioning member 44, and the second contact surface 40 abuts against the side surface SF of the luggage CA via the second cushioning member 46. Therefore, the corner guard 10 can be stably placed on the corner of the luggage CA before the belt BT is stretched across it.

[0038] Furthermore, according to the corner guard 10 of this embodiment, a corner portion 22 is formed at the portion connecting the top portion 18 and the side portion 20 of the corner guard 10, having a corner ridge portion 24 that protrudes outward. Therefore, the corner portion 22 connecting the top portion 18 and the side portion 20 can be reinforced, and the overall strength of the corner guard 10 can be improved. Moreover, when a belt BT is stretched across it, the corner ridge portion 24 can concentrate on supporting the belt BT, so the load acts directly on the corner of the cargo CA, and when lifted, the corner guard 10 and the cargo CA with the belt BT stretched across them can be stabilized. In addition, since the load, i.e., the weight of the cargo CA, can be concentrated at the corner portion 22, the corner guard 10 can be stabilized, and the load on the cargo CA from the top portion 18 and the side portion 20 can be reduced.

[0039] Furthermore, the corner guard 10 according to this embodiment is provided with guide portions 30 formed along the length direction and protruding outward at both ends in the width direction of the top surface portion 18 and the side surface portion 20. This allows for limiting the widthwise sliding of the belt BT stretched over the corner guard 10 when the cargo CA is lifted, thereby stabilizing the corner guard 10 and the cargo CA. The guide portion 30 also includes a convex portion 32 that protrudes outward from the adjacent recess 34 and a recess 34 that is recessed inward from the convex portion. Therefore, when the belt BT is stretched along the width direction of each unit 12, 14, and 16, the adjacent convex portion 32 can limit the sliding of the belt BT by placing the belt or string over the recess 34. This allows the belt BT to be stably stretched over the width direction of the corner guard 10 as well.

[0040] Furthermore, the corner guard 10 according to this embodiment has a first raised portion 26 formed continuously with the corner raised portion 24 on the top surface portion 18 side, and a second raised portion 28 formed continuously with the corner raised portion 24 on the side surface portion 20 side, and the second raised portion 28 is formed to be heavier than the first raised portion 26. Therefore, when a load CA with a belt BT stretched over it is lifted, the belt BT makes contact over a wide area, and the strength of the side surface portion 20 on which the load is applied can be improved. In addition, when the corner guard 10 is placed at the corner of the load CA, the downward force of gravity along the side of the load CA can be increased, and the top surface portion 18 and, consequently the corner guard 10 can be placed at the corner of the load CA more stably.

[0041] Furthermore, according to the corner guard 10 of this embodiment, holes 36 are formed through the top surface 18 and side surface 20 of the second unit 14. Therefore, a user who intends to place the corner guard 10 on the corner of the luggage CA can insert their hand into the hole 36 of the corner guard 10 and grasp it, making it easy to attach the corner guard 10 to the luggage CA and allowing the corner guard 10 to be stably attached to the luggage CA.

[0042] Furthermore, according to the corner guard 10 of this embodiment, the first contact surface 38 of the top surface portion 18 that abuts against the top surface TF of the luggage CA and the second contact surface 40 of the side surface portion 20 that abuts against the side surface SF of the luggage CA are configured to form an angle between 90 and 110 degrees. Therefore, the corner guard 10 can be fitted to the corner of the luggage CA and attached stably.

[0043] Furthermore, according to the corner guard 10 of this embodiment, a first cushioning member 44 and a second cushioning member 46 are attached to the first contact surface 38 of the top surface 18 and the second contact surface 40 of the side surface 20. Therefore, when the load CA is lifted, the load acting on the load CA from the top surface 18 side and the side surface 20 side can be mitigated.

[0044] As described above, the corner guard 10 according to this embodiment can be used for moving or transporting cargo CA while ensuring strength and improving stability.

[0045] Although embodiments of the corner guard 10 have been described above, the present invention is not limited to the above embodiments. Those skilled in the art will understand that various modifications of the above embodiments are possible. [Explanation of Symbols]
