Description

Technical Field

[0001] This invention relates to a support tool and a handling tool. Background Technology

[0002] When shipping heavier products, the product is placed on a pallet and a forklift is used to lift the product and pallet together for handling.

[0003] In this case, a support tool called a bracket is used to support the products on the pallet to prevent them from falling off during handling. Then, a cushioning material such as expanded polystyrene is sandwiched between the pallet and the products to prevent them from being damaged by vibration. After these operations are performed, the handling begins.

[0004] The pre-transfer work (i.e., the installation of brackets and the setting of cushioning materials) requires manpower and time. In order to improve the efficiency of the transfer operation, the time of this work needs to be shortened.

[0005] Here, Patent Document 1 discloses the originality of the shape of the bracket fixed on the device.

[0006] Patent Document 1: Japanese Patent Application Publication No. 10-095429 Summary of the Invention

[0007] The object of the present invention is to provide a support tool that can increase the amount of deformation when a load is applied in the direction of gravity, thereby improving the cushioning performance, compared to a case that does not have three plates including a first plate, a second plate, and a third plate with different angles.

[0008] The invention involved in Scheme 1 is a support tool, which includes:

[0009] Section 1;

[0010] The second plate rises obliquely from the first plate and changes its angle with the first plate by elastic deformation when a load is applied.

[0011] The third plate, rising obliquely from the edge of the upright side of the second plate along the direction that overlaps the second plate when projected downwards, and utilizing elastic deformation to reduce the angle between itself and the second plate when a load is applied; and

[0012] The support portion is connected to and extends from the edge of the upright side of the third plate portion, thereby supporting the supported object.

[0013] The invention involved in Scheme 2 is the support tool described in Scheme 1, wherein the support portion is composed of a hook-shaped fourth plate portion, which is connected to and extends from the edge of the upright side, and then bends and extends further.

[0014] The invention involved in Scheme 3 is a support tool described in Scheme 2, wherein the third plate portion is wider than the support portion, and the support portion has a first groove portion with a downwardly cut shape on both sides.

[0015] The invention involved in Scheme 4, in any one of Schemes 1 to 3, further includes an abutting portion that extends along the second plate portion from the side edge of the third plate portion when it is separated from the second plate portion, and abuts against the second plate portion when the angle between the second plate portion and the third plate portion decreases.

[0016] The supporting tool of any one of Schemes 1 to 4 in Scheme 5 further includes an abutting portion that extends from the side edge of the third plate portion toward the underside of the supporting object when it is separated from the supporting object supported by the supporting portion, and receives the abutment of the supporting object when the angle between the second plate portion and the third plate portion decreases.

[0017] The invention involved in Scheme 6, in any one of Schemes 1 to 3, includes a fifth plate portion.

[0018] The fifth plate extends from the side edge of the third plate along the second plate, with its lower end face separated from the second plate, and extends from the side edge of the third plate downwards from the supported object, with its upper end face separated from the supported object.

[0019] When the angle between the second plate and the third plate decreases, the lower end face of the fifth plate abuts against the second plate. When the angle between the first plate and the second plate further changes while the lower end face is abutting against the second plate, the fifth plate bears the abutment of the supporting object against the upper end face.

[0020] The invention involved in Scheme 7 is a support tool described in Scheme 6, wherein the fifth plate portion has a second groove portion formed by cutting the lower end face upward along the side edge of the third plate portion.

[0021] The invention involved in Scheme 8 is the support tool described in Scheme 6 or 7, wherein the fifth plate portion is composed of a pair of fifth plate portions that are respectively connected to the left and right side edges of the third plate portion which are inclined and erected.

[0023] A support platform has a horizontal plate portion and a beam portion extending in contact with the lower surface of the horizontal plate portion, and supports a transportable object; and

[0024] The support tool according to any one of Schemes 1 to 8 is placed on the upper surface of the cross plate portion at a position where the cross plate portion overlaps with the beam portion.

[0025] Invention Effects

[0026] According to the support tool of the first embodiment, compared with the case that does not have three plates including a first plate, a second plate, and a third plate with different angles, the amount of deformation when a load is applied in the direction of gravity can be increased to improve the buffering performance.

[0027] Furthermore, the support tool according to the first scheme can shorten the operation time before handling compared to the case of using different types of components, namely brackets and cushioning materials.

[0028] According to the second embodiment, the support tool can reliably support the supported object compared to the case where the support part does not have a hook shape.

[0029] According to the support tool of the third scheme, compared with the case without the first groove, the elasticity of the support can be improved relative to vibration in the horizontal direction, thus becoming a structure that is not easily damaged.

[0030] According to the support tool of the fourth embodiment, compared with the case without the abutment part, excessive reduction of the angle between the second plate part and the third plate part can be suppressed.

[0031] According to the support tool of the fifth scheme, compared with the case where there is no abutment, excessive deformation can be suppressed to prevent the support from falling off the supported object.

[0032] According to the support tool of the sixth embodiment, compared with the case without the fifth plate, excessive reduction of the angle between the second and third plates can be suppressed, while further excessive deformation can be suppressed to prevent the support from falling off the supported object.

[0033] According to the support tool of the seventh embodiment, compared with the case without the second groove, the elastic force of the elastic deformation until the lower end face of the fifth plate comes into contact with the second plate can be adjusted in a weakening direction.

[0034] According to the support tool of the eighth scheme, compared with the case where only a fifth plate extending from one side edge of the third plate is formed, it is possible to achieve left-right balanced deformation.

[0035] According to the handling tool of the 9th scheme, the expected deformation can be achieved compared with the case where the support tool is placed in a different position. Attached Figure Description

Detailed Implementation

[0046] Hereinafter, comparative examples will be described first, followed by descriptions of embodiments of the present invention.

[0047] Figure 1 This is a diagram illustrating an example of a method of supporting an object on a pallet, used as a comparative example.

[0048] Figure 1 (A) shows a portion of the bottom of a device 20, which serves as a support object and is placed on a pallet 10. Casters 21 are provided at the bottom of the device 20. Furthermore, the device 20 is protected by a bracket 30 for limiting lateral swaying and a cushioning material 40 for buffering longitudinal swaying, and is transported together with the pallet 10.

[0049] Figure 1 (B) Figure 1(C) is a side view and a front view of the bracket 30. The upper part of the bracket 30 is provided with a hook 31 that is inserted into the support opening (not shown) of the device 20. Furthermore, the bracket 30 restricts the lateral swaying of the device 20 by inserting the hook 31 into the support opening of the device 20.

[0050] In this comparative example, after the device 20 is placed on the pallet 10, it needs to be supported by two types of support tools: the bracket 30 and the cushioning material 40. Therefore, the pre-handling operations are cumbersome and time-consuming, thus requiring improvements in operational efficiency.

[0051] Figure 2 This diagram illustrates an example of a method for using a support device on a pallet, which is an example of a support tool in this embodiment.

[0052] Here, also with Figure 1 In the comparative example shown, a device 20 with casters 21 is mounted on a pallet 10. The pallet 10 has a cross plate 11 and a longitudinal beam 12 extending in contact with the lower surface of the cross plate 11, and serves to support a transport object (here, the device 20).

[0053] The pallet 10, the cross plate 11, and the longitudinal beam 12 correspond to one example each of the support platform, the cross plate portion, and the beam portion described in this invention. Furthermore, the combination of the pallet 10 and the support tool 50, which clamps the cross plate 11 and is placed on the longitudinal beam 12, corresponds to one example of the handling tool described in this invention.

[0054] The device 20 is supported on the pallet 10 by a plurality of identical support tools 50, which are simplified herein. These support tools 50 also serve as… Figure 1 The function of the bracket 30 and the cushioning material 40 is shown. These multiple support tools 50 are placed at the position where the cross plate 11 sandwiching the pallet 10 overlaps with the longitudinal beam 12. As described later, the support tool 50 will elastically deform, but placing it at the position overlapping with the longitudinal beam 12 will result in less deflection of the cross plate 11, achieving the desired deformation compared to placing it at a position other than the longitudinal beam 12.

[0055] The following is a description of the support tool.

[0056] Figure 3 and Figure 4 These are the side and front views of the support tool.

[0057] The support tool 50 is formed by sheet metal processing of a metal sheet. However, there are no restrictions on the material; if the object to be supported is relatively lightweight, it can also be made of plastic.

[0058] The support tool 50 includes a first plate portion 51, a second plate portion 52, a third plate portion 53, and a support portion 54.

[0059] The first plate portion 51 is provided with holes 511 for fixing to the pallet 10.

[0060] Furthermore, the second plate portion 52 is tilted upwards from the first plate portion 51. If a load is applied, the second plate portion 52 will use elastic deformation to change the angle between itself and the first plate portion 51.

[0061] Furthermore, the third plate portion 53 is inclined to stand up from the edge of the second plate portion 52 on the side where it is erected, along the direction in which it overlaps the second plate portion 52 when projected downwards. If a load is applied, the third plate portion 53 uses elastic deformation to reduce the angle between itself and the second plate portion 52.

[0062] Furthermore, the support portion 54 connects to and extends from the edge of the upright side of the third plate portion 53, and serves to support the supported object. Specifically, the support portion 54 is composed of a hook-shaped fourth plate portion, which connects to the edge of the upright side of the third plate portion 53 and extends further upward, then bends and extends further. This hook-shaped support portion 54 is inserted into the component device 20 (see reference 20). Figure 2 The support opening 221 of the lower support frame 22 of the device 20 is inserted into the support opening 221 of the support frame 22. The support part 54 can suppress the lateral swaying of the device 20 equipped with the support frame 22 by inserting into the support opening 221 of the support frame 22.

[0063] Furthermore, the third plate portion 53 is wider than the support portion 54, and has a first groove portion 531 with a downward cut shape on both sides of the support portion 54. Compared with the case without the first groove portion 531, by forming the first groove portion 531, the elasticity of the support portion 54 relative to vibration in the horizontal direction is improved, thereby forming a structure that is not easily damaged.

[0064] Furthermore, the support tool 50 also includes a fifth plate portion 55. This fifth plate portion 55 has the following shape: when its lower end face 551 is separated from the second plate portion 52, it extends from the side edge of the third plate portion 53 along the second plate portion 52; and when its upper end face 552 is separated from the supported object, i.e., the device 20, supported by the support portion 54, it extends from the side edge of the third plate portion 53 downwards towards the device 20. If the angle between the second plate portion 52 and the third plate portion 53 decreases due to an applied load, the fifth plate portion 55 abuts its lower end face 551 against the second plate portion 52.

[0065] Figure 5 This is a schematic diagram showing the behavior of a support tool when a horizontal load is applied to the supported object, i.e., the device.

[0066] If device 20 is subjected to pressure due to the support frame 22, which is part of device 20 Figure 5 If the load in the horizontal direction indicated by the middle arrow X causes the movement, then as follows:Figure 5 As shown, the support tool 50 is deformed into a hook shape with the support portion 54 facing upwards, so that the hook-shaped support portion 54 is not easy to fall off from the support opening 221. At this time, the support frame 22 of the device 20 contacts the upper end surface 552 of the fifth plate portion 55, thereby suppressing the deformation of the direction in which the support portion 54 falls off from the support opening 221, and has the effect of suppressing falling off.

[0067] When a load is applied, by abutting the lower end face 551 against the second plate portion 52, the excessive reduction of the angle between the second plate portion 52 and the third plate portion 53 can be suppressed compared to a structure in which the lower end face 551 is not abutted against the second plate portion 52.

[0068] Furthermore, when a load is applied, compared to a structure where the upper end face 552 does not bear the contact with the device 20, the support portion 54 can be prevented from falling off the supported object, i.e., the device 20, due to excessive deformation.

[0069] The fifth plate portion 55 is composed of a pair of fifth plate portions that are respectively connected to the left and right side edges of the third plate portion 53, which are inclined and erect. In this way, by forming a pair of fifth plate portions 55, compared with the case of forming only one fifth plate portion 55 extending from one side edge of the third plate portion 53, a left-right balanced deformation can be achieved.

[0070] Here, the lower end face 551 of the fifth plate portion 55 corresponds to the abutting portion as described in this invention. Furthermore, the upper end face 552 of the fifth plate portion 55 corresponds to an example of the abutting portion as described in this invention.

[0071] Furthermore, a second groove 553 is formed on the fifth plate portion 55, which is shaped by cutting the lower end face 551 upward along the side edge of the third plate portion 53. By forming this second groove 553, compared with the case where there is no second groove 553, the elastic force of the elastic deformation until the lower end face 551 of the fifth plate portion 55 comes into contact with the second plate portion 52 can be adjusted in a weakening direction.

[0072] According to the support tool 50, compared with the case that does not have three plates including a first plate, a second plate, and a third plate with different angles, the amount of deformation when a load is applied in the direction of gravity can be increased to improve the cushioning performance.

[0073] Furthermore, according to the support tool 50, and the reference Figure 1 Compared to the use of bracket 30 and cushioning material 40, the cost of parts and pre-shipment work time can be almost halved.

[0074] Figure 6 This is a side view showing another example of a support tool. It is indicated by the same symbols as the support tool 50 described so far, with only the differences explained.

[0075] As Figure 6 In another example of the support tool 50 shown, the first plate portion 51 extends in the opposite direction to the portion other than the first plate portion 51. The first plate portion 51 may also extend along this direction.

[0076] Figure 7 This is a side view showing yet another example of a support tool. (and) Figure 6 In another example, the same symbols are used to indicate the support tool 50 described so far, and only the differences are explained.

[0077] As Figure 7 In another example of the support tool 50 shown, the first plate portion 51 extends vertically. Furthermore, the first plate portion 51 is mounted to the vertical wall 13 of the pallet 10, which has steps or recesses, by fasteners 61 such as bolts and nuts. The first plate portion 51 can also extend vertically in this manner.

[0078] Furthermore, while the structure described here is one in which the support opening 221 is provided on the side of the support frame 22 and the support portion 54 is inserted into the support opening 221 from the side, a different structure can also be used: the support opening 221 is formed on the bottom surface of the support frame 22, and the support portion 54 is inserted into the support opening 221 formed on the bottom surface. In this case, the third plate portion 53 (see reference) Figure 4 It abuts against the bottom surface of the support frame 22, causing the support tool 50 to deform, thereby playing a buffering role.

[0079] The embodiments of the present invention described above are provided for illustrative purposes. Furthermore, these embodiments do not encompass the entirety of the invention, nor do they limit the invention to the disclosed methods. It will be apparent to those skilled in the art that various modifications and variations will be readily understood. These embodiments were chosen and described to most readily explain the principles and applications of the invention. Thus, those skilled in the art can understand the invention through various modifications that are assumed to optimize specific uses of various embodiments.
