Description

[Technical Field]

[0001] The present invention relates to a panel removal tool for removing a panel having a plurality of magnets from a structure. [Background Art]

[0002] There is a configuration in which the surfaces of structures such as walls and columns are formed of a magnetic material (mainly iron), and a panel having a plurality of magnets is attached to the surface of the structure. As a means for removing this panel from a structure, Patent Document 1 discloses a removal tool (magnet holder).

[0003] When the removal tool described in Patent Document 1 is attracted, the structure is configured such that the attractive force between the magnet and the removal tool is stronger than the attractive force between the structure and the magnet. Accordingly, when the removal tool is pulled, the magnets of the panel can be pulled away from the structure. Although the panel can be recovered in this way, it is then necessary to remove the panel from the removal tool. [Prior Art Literature] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application No. 2023-144309 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] In the panel of Patent Document 1, when the attractive force of the magnet increases, the attractive force between the magnet and the removal tool also increases. In the removal tool described in Patent Document 1, a lateral wall is formed on the yoke in order to increase the attractive force in the detachable tool. However, due to the presence of this lateral wall, it is necessary to pull the detachable tool away from the removal tool in the vertical direction. As a result, the detaching operation must be performed with a force equal to the attractive force, which makes it difficult to remove the magnet from the removal tool.

[0006] The present invention aims to provide a panel removal tool that can not only remove panels from structures but also easily remove panels that have adhered to it. [Means for solving the problem]

[0007] To solve the above problems, a typical configuration of the panel removal tool according to the present invention is a panel removal tool for removing a panel having multiple magnets from a structure, comprising a frame, a link mechanism attached to the frame, and a plurality of magnetic bodies attached to the link mechanism and supported so as to be movable relative to the frame, wherein the plurality of magnetic bodies are arranged in positions corresponding to the plurality of magnets, and the link mechanism moves the magnetic bodies parallel to the adsorption surface formed by the adsorption of the magnetic bodies and the magnets.

[0008] The link mechanism described above is preferably a toggle clamp having a rotatably mounted lever.

[0009] In the toggle clamp described above, it is preferable that the direction of rotation of the lever is parallel to the panel.

[0010] It is preferable that the above-mentioned frame is provided with a handle. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a panel removal tool that can not only remove panels from structures but also easily remove panels that have adhered to it. [Brief explanation of the drawing]

[0012] [Figure 1] This figure shows a schematic configuration of a panel removal tool according to an embodiment of the present invention. [Figure 2] Figure 1 shows the panel removal tool and the main parts of the panel. [Figure 3] This diagram illustrates the toggle clamp of the panel removal tool shown in Figure 1. [Figure 4]This diagram shows the procedure for removing a panel from a structure using the panel removal tool shown in Figure 1. [Figure 5] Figure 4 illustrates the operation of the subsequent panel removal tool. [Figure 6] Figure 5 shows the procedure for removing the panel using the subsequent panel removal tool. [Modes for carrying out the invention]

[0013] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific numerical values ​​shown in these embodiments are merely examples to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustrations.

[0014] Figure 1 shows a schematic configuration of the panel removal tool 100 in an embodiment of the present invention. Figure 1(a) shows the panel removal tool 100 and the panel 200. Figure 1(b) shows the panel 200 in a state where it is adhering to the structure 300.

[0015] The panel removal tool 100 is a tool used to remove the panel 200 from a structure 300 such as a wall or column. The panel 200 is, for example, a plastic board printed with an advertisement or poster, or a solar panel. Multiple (in this case, 10) mounting fixtures 204 are attached to the side 202 of the panel 200. The mounting fixtures 204 of the panel 200 include magnets 206 (see Figure 2(b)).

[0016] The surface 302 of the structure 300 is made of a magnetic material (mainly iron). Therefore, the panel 200 is attracted to the structure 300 by the magnetic force (attractive force) between the magnets 206 of the multiple mounting fixtures 204 and the surface 302 of the structure 300, as shown in Figure 1(b).

[0017] A panel removing tool 100 comprises a frame body 102, a plurality (ten in this case) of toggle clamps 104, and suction blocks 106. The frame body 102 is a rectangular frame formed to match the outer shape of a panel 200. Two handles 107 are provided on the frame body 102. Accordingly, an operator can carry and move the panel removing tool 100 by gripping the handles 107 of the frame body 102, thereby improving workability.

[0018] The toggle clamp 104 is a link mechanism attached to the frame body 102. The suction block 106 is made of a magnetic material (mainly iron), attached to the toggle clamp 104, and movably supported relative to the frame body 102. The plurality of suction blocks 106 are arranged at positions corresponding to the plurality of fixtures 204 of the panel 200.

[0019] Furthermore, the toggle clamp 104 (as will be described later) moves the suction block 106 in parallel relative to a suction surface 108 (see FIG. 5(a)) formed by the suction between the suction block 106 and the fixture 204 of the panel 200.

[0020] FIG. 2 is a diagram showing main parts of the panel removing tool 100 and the panel 200 of FIG. 1. FIG. 3 is a diagram illustrating the toggle clamp 104 of the panel removing tool 100 of FIG. 1. Note that in FIG. 3, the toggle clamp 104 is shown with the frame body 102 omitted.

[0021] In the panel removing tool 100, the suction blocks 106 attached to the toggle clamps 104 are arranged at positions corresponding to the fixtures 204 of the panel 200. Accordingly, the panel removing tool 100 can cause the suction blocks 106 to face the fixtures 204 of the panel 200 as shown by arrow A in FIG. 2(a).

[0022] As shown in Figure 2(b), the mounting fixture 204 for panel 200 consists of a plurality of thin plate-shaped magnets 206, a plurality of thin plate-shaped yokes 208, and a bolt 210. These plurality of magnets 206 and plurality of yokes 208 are arranged alternately and further integrated by the bolt 210 passing through them. The mounting fixture 204 is attached to the side edge 202 of panel 200 by bolt 214 via a bracket 212.

[0023] The toggle clamp 104 includes a base member 110 as shown in Figure 3(a). The base member 110 is attached to the side wall 114 of the frame 102 by bolts 112 as shown in Figure 2(a). The toggle clamp 104 also includes a lever 116, a link member 118, a shaft 120, a support member 122, and a fixing member 124 as shown in Figure 3(a). The lever 116 is attached to the link member 118.

[0024] The link member 118 is a member that connects the shaft 120 and the support member 122. The link member 118 has a pair of spaced-apart connecting portions 126, with the shaft 120 sandwiched between the pair of connecting portions 126. The support member 122 also has a pair of spaced-apart plate-like portions 128, with the connecting portions 126 of the link member 118 and the fixing member 124 sandwiched between the pair of plate-like portions 128.

[0025] The connecting portion 126 of the link member 118 is rotatably connected to one end 120a of the shaft 120 via a connecting pin 130. Furthermore, the connecting portion 126 of the link member 118 is rotatably connected to one end 128a of the plate-shaped portion 128 of the support member 122 via a connecting pin 132.

[0026] Furthermore, the other end 128b of the plate-shaped portion 128 of the support member 122 is fixed to the fixing member 124 by a fixing pin 134. The fixing member 124 is attached to the base member 110 while being sandwiched between the plate-shaped portion 128 of the support member 122. As shown in Figure 3(a), the shaft 120 passes through the fixing member 124 and the base member 110. In addition, a suction block 106 is attached to the other end 120b of the shaft 120.

[0027] Furthermore, as shown in Figure 2(a), a cover member 138 is fixed to the bottom wall 136 of the frame 102. In Figures 3(a) and 3(b), the cover member 138 is shown by a dotted line. The cover member 138 has a top plate 140 and two side plates 142. The top plate 140 is fixed to the bottom wall 136 of the frame 102 and is separated upward from the suction block 106. The two side plates 142 are fixed to the top plate 140 and are separated laterally from the suction block 106.

[0028] In this way, the cover member 138 surrounds the suction block 106 with its lower side open. This allows the cover member 138 to protect the suction block 106 from interfering with other components. The cover member 138 also functions as a guide when the panel removal tool 100 is brought close to the panel 200 to align the suction block 106 with the mounting fixture 204 on the panel 200.

[0029] When the operator grips the lever 116 of the toggle clamp 104 and rotates it in the direction indicated by arrow B in Figure 3(a), the link member 118 rotates around the connecting pin 132. The connecting portion 126 of the link member 118 is rotatably connected to one end 120a of the shaft 120 via the connecting pin 130, as described above.

[0030] Therefore, as the connecting portion 126 of the link member 118 rotates, one end 120a of the shaft 120 is pushed toward the base member 110 via the connecting pin 130. As a result, as shown in Figure 3(b), the suction block 106 attached to the other end 120b of the shaft 120 moves away from the base member 110 (see arrow C) and pops out from the cover member 138 fixed to the frame 102. In this way, the suction block 106 is attached to the toggle clamp 104, which is a link mechanism, and is supported so as to be movable relative to the frame 102.

[0031] Figure 4 shows the procedure for removing a panel 200 from a structure 300 using the panel removal tool 100 shown in Figure 1. First, the worker grasps the handle 107 of the frame 102 of the panel removal tool 100 and aligns the multiple suction blocks 106 attached to the toggle clamp 104 with the multiple mounting fixtures 204 of the panel 200 that are adsorbed to the surface 302 of the structure 300 shown in Figure 4(a). This allows the worker to adsorb the panel 200 to the panel removal tool 100.

[0032] Next, the worker grasps the handle 107 of the panel removal tool 100 and moves the panel removal tool 100 away from the structure 300. At this time, the thickness of the suction block 106 is set so that it is thicker than the wall of the structure 300. As a result, the magnetic path of the magnet 206 of the mounting fixture switches so that more current flows towards the suction block 106 than towards the structure 300. This allows the worker to remove the panel 200 from the structure 300 while the panel 200 is attached to the panel removal tool 100, as shown in Figure 4(b).

[0033] Figure 5 is a diagram illustrating the operation of the panel removal tool 100, which follows Figure 4. Figure 6 is a diagram illustrating the procedure for removing the panel 200 from the panel removal tool 100, which follows Figure 5.

[0034] Figure 5(a) shows the panel 200 attached to the panel removal tool 100 by suction, as shown in Figure 4(b). The toggle clamps 104 shown in Figures 5(a) and 5(b) correspond to the toggle clamps 104 shown in Figures 3(a) and 3(b), respectively.

[0035] In the panel removal tool 100 shown in Figure 5(a), the magnet 206 included in the mounting fixture 204 of the panel 200 is attracted to the suction block 106 attached to the toggle clamp 104. As a result, as shown in Figure 5(a), an attraction surface 108 is formed when the bottom surface 144 of the suction block 106 and the top surface 216 of the mounting fixture 204 are attracted to each other.

[0036] Next, the worker grasps the lever 116 of the toggle clamp 104 and rotates it as shown by arrow B in Figures 5(b) and 6(a). This causes the shaft 120 of the panel removal tool 100 to be pushed toward the base member 110, as described above.

[0037] As a result, the suction block 106 moves away from the base member 110, as shown by arrow C in Figures 5(b) and 6(a), and moves parallel to the suction surface 108 (see Figure 5(a)). In other words, the bottom surface 144 of the suction block 106 moves in the direction indicated by arrow C relative to the top surface 216 of the mounting fixture 204, as shown in Figure 5(b).

[0038] This reduces the magnetic force (attractive force) between the suction block 106 of the panel removal tool 100 and the magnet 206 included in the mounting fixture 204 of the panel 200. The worker can then remove the panel 200 from the panel removal tool 100 by operating all the levers 116 of the multiple toggle clamps 104 of the panel removal tool 100, as shown in Figure 6(b).

[0039] Furthermore, if an attempt were made to remove the panel 200 by moving the suction block 106 vertically rather than parallel to the mounting fixture 204 of the panel 200, the force required to remove the panel 200 would be greater than the force required for parallel movement.

[0040] In contrast, the panel removal tool 100 attaches a suction block 106 to a toggle clamp 104, and moves the suction block 106 parallel to the suction surface 108 formed by the suction between the suction block 106 and the mounting fixture 204 of the panel 200. Therefore, with the panel removal tool 100, not only can the panel 200 be removed from the structure 300, but the panel 200 that has adhered to it can also be easily removed.

[0041] Furthermore, the panel removal tool 100 is equipped with a toggle clamp 104 as a link mechanism, so that the operator can operate the lever 116 to maintain the position of the suction block 106 according to the position of the lever 116.

[0042] Furthermore, in the toggle clamp 104, the rotation direction of the lever 116 (see arrow B) is parallel to the panel 200 when it is attached to the suction block 106. Therefore, when the operator operates the lever 116, the lever 116 does not come into contact with the panel 200. Thus, the panel removal tool 100 makes it easy to operate the lever 116 and prevents the lever 116 from damaging the panel 200.

[0043] In the above description, a configuration in which one suction block 106 is equipped with one toggle clamp 104 was illustrated. However, the present invention is not limited to this, and a configuration in which multiple suction blocks 106 can be moved with one toggle clamp is also possible. Furthermore, other mechanisms such as a cam and lever or a screw and handle may be used as the link mechanism instead of a toggle clamp.

[0044] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these examples. It will be obvious to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.
