Description

[Technical Field]

[0001] The present invention relates to an article fastener for attaching an article to a magnetic wall by magnetic attraction. [Background technology]

[0002] For example, when mounting an item such as a flat-screen television on a wall, it is common to fasten a bracket to the wall with screws or the like, and then fasten the back of the television to the bracket with a fastening means or the like. If the bracket is fastened to the wall with screws or the like, and the mounting position of the bracket is changed to reposition the television due to room rearrangement or the like, machining marks such as screw holes will remain on the wall, spoiling the appearance.

[0003] These problems can be solved by using a television mounting fixture such as that described in Patent Document 1. The mounting fixture described in Patent Document 1 mounts a television to a wall by fastening multiple magnetic sheets to the back of the television or to the back of a plate-shaped bracket that is attached to the back of the television, and then magnetically attaching these magnetic sheets to a magnetic wall, so that no processing of the wall surface is required and the mounting position of the television on the wall can be freely changed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7153830 (page 5, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0005] In the television mount described in Patent Document 1, since a heavy television needs to be supported by a magnetic wall, multiple magnetic sheets are attached to the back of the television or the back of a bracket attached to the back of the television, thereby increasing the magnetic adhesion area (magnetic force) to the magnetic wall. However, if the magnetic adhesion area of ​​the magnetic sheets is large, it is difficult to easily peel the magnetic sheets from the magnetic wall when changing the mounting position of the television due to room rearrangement, etc., and if an attempt is made to forcibly peel the magnetic sheets from the magnetic wall by inserting a tool between the magnetic wall and the television or bracket, there is a risk of scratching the magnetic wall or the television or deforming the bracket.

[0006] The present invention has been made in light of these problems, and aims to provide an article fixture that has a large magnetic attraction force yet can be easily removed from a magnetic wall. [Means for solving the problem]

[0007] In order to solve the above problems, the article attachment device of the present invention comprises: An article attachment device that attaches an article to a magnetic wall by magnetic force, It is characterized by comprising a plurality of vertically long rod-shaped bodies on the left and right to which articles can be attached, connecting portions that can be bent in the thickness direction to connect the opposing portions of adjacent rod-shaped bodies, and a magnetic sheet that is fixed in the vertical direction to the back surfaces of the plurality of rod-shaped bodies and magnetically attached to the magnetic wall. According to this feature, the magnetic sheet affixed to the backsides of the multiple rods is magnetically attached to the magnetic wall, thereby increasing the overall magnetic adhesion area of ​​the magnetic sheet. As a result, the article fixture can be attached to the magnetic wall with a strong magnetic force against vertical loads, and there is no risk of misalignment even when a heavy article is attached to the article fixture. Furthermore, because the opposing portions of the multiple rods on the left and right sides are connected to each other by connecting portions that can be bent in the thickness direction, when removing the article fixture from the magnetic wall, the magnetic sheet on each rod at either the left or right end can be peeled off from the magnetic wall one by one. Therefore, even an article fixture with a strong magnetic force can be easily removed from the magnetic wall and its mounting position changed. Furthermore, because the connecting portions connecting the rods to each other bend in the thickness direction, the article fixture can be folded into a roll when not in use or when transporting.

[0008] The rod-shaped body is made of a non-magnetic material and is hollow, and a core material having a strength greater than that of the rod-shaped body is housed inside the rod-shaped body along the vertical direction. According to this feature, the bending strength of the rod-shaped body can be increased while reducing its weight.

[0009] At least one of the core materials is provided with an attachment portion for attaching an attachment member of the article. According to this feature, the load of the article can be supported by the high-strength core material, so the support strength of the article on the rod-shaped body is increased. When the attachment portions are provided on multiple core materials on the left and right, the multiple core materials can stably support an article with a large width.

[0010] The mounting portion is characterized in that a plurality of mounting portions are provided in the vertical direction. According to this feature, a heavy article can be stably supported by the multiple upper and lower mounting portions, and the mounting height of the article can be changed.

[0011] The core material is made of a ferromagnetic material and is arranged inside the rod-shaped body so as to be adjacent to the magnet sheet and protrude laterally from both the left and right ends of the magnet sheet. According to this feature, the magnetic sheet is sandwiched between the core material made of a ferromagnetic material and the magnetic wall, forming a closed magnetic circuit, which prevents leakage of the magnetic field lines of the magnetic sheet and increases the magnetic flux density. As a result, the yoke effect of the core material concentrates the magnetic flux of the magnetic sheet on the magnetic wall, allowing the article fixture to be attached to the magnetic wall with a strong magnetic attraction. Furthermore, because the core material made of a ferromagnetic material prevents leakage of the magnetic field lines of the magnetic sheet, there is no risk of magnetic influence on electrical appliances attached to the article fixture.

[0012] The connecting portion is characterized in that it is continuous in the vertical direction. According to this feature, the connection strength between adjacent rods is increased, so that the individual rods are prevented from shifting downward due to the weight of the article.

[0013] The front surface of the rod-shaped body is characterized by being formed into a convex curved surface. According to this feature, when the rods on either the left or right side are peeled off one by one from the wall surface, one side end of the curved surface of the rod that was peeled off first comes into contact with the curved surface of the rod to be peeled off next, and a large peeling moment acts on that rod, so that each rod can be easily peeled off from the magnetic wall in turn.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the article fastener of the present invention will be described below with reference to the accompanying drawings. [Example]

[0016] An article fixture according to a first embodiment will be described with reference to FIGS. 1 to 5. The article fixture 1 is designed to attach an article, such as a television 3, to the front surface of a magnetic wall 2 made of a ferromagnetic steel material by magnetic attraction. The fixture includes a plurality of vertically elongated rods 4, a connecting portion 5 connecting the opposing portions of adjacent rods 4, and a magnetic sheet 6 that is fixed with an adhesive to the back surface of each rod 4 and magnetically attached to the front surface of the magnetic wall 2. The vertical dimension of the magnetic sheet 6 is approximately the same as that of the rods 4, but the horizontal dimension is slightly smaller than that of the rods 4, thereby increasing the magnetic adhesion area of ​​the magnetic sheet 6 relative to the magnetic wall 2 and enhancing the magnetic force. In this embodiment, as shown in FIG. 3, wallpaper 7 is attached to the front surface of the magnetic wall 2, and the magnetic sheet 6 is magnetically attached via the wallpaper 7. However, the wallpaper 7 may be omitted and the magnetic sheet 6 may be magnetically attached directly to the magnetic wall 2.

[0017] Each rod-shaped body 4 is hollow and open both upward and downward, with a convexly curved front surface, and is formed by extrusion molding of a non-magnetic synthetic resin material. The upper and lower openings of each rod-shaped body 4 are closed by caps 8, 8, but the caps 8 may be omitted. The connecting portion 5 connects the opposing portions of adjacent rod-shaped bodies 4, excluding the caps 8, in the vertical direction, and is formed integrally at the same time as the extrusion molding. The thickness of the connecting portion 5 is thinner than that of the rod-shaped body 4 so that it can bend in the thickness direction. Each rod-shaped body 4 is reinforced by a pair of left and right ribs 4a, 4a that are integrally formed inside and continue in the vertical direction.

[0018] The front wall 4b of the two rod-shaped bodies 4, 4 spaced apart on the left and right sides of the center has multiple slits 10 formed on the top and bottom for inserting a pair of left and right brackets 9, 9, which are mounting members for the television 3, toward the core material 11, which will be described later.

[0019] A core 11 made of a ferromagnetic steel material is housed vertically within the hollow portion of each rod-shaped body 4. The core 11 can be inserted into a mold for extrusion molding the rod-shaped body 4 and fixed integrally to the inside of the rod-shaped body 4.

[0020] As shown in Figure 3, the core material 11 of each rod-shaped body 4 is bent forward so that the central part in the left-right direction forms a U-shaped cross section, and both ends in the left-right direction form flat plates facing up and down, and the flat plate-shaped portion is positioned abutting against the inner surface (front surface) of the rear wall 4c of the rod-shaped body 4 so as to be closely opposite the magnetic sheet 6 across the rear wall 4c.

[0021] At the center of the bent portion, a plurality of upper and lower locking holes (mounting portions) 12 for locking and mounting the bracket 9 are formed so as to face each of the slits 10 .

[0022] The left and right dimensions of the core material 11 are formed so that it protrudes a predetermined distance laterally from both the left and right ends of the magnet sheet 6. When the core material 11 made of such a ferromagnetic material is housed inside the rod-shaped body 4, the magnet sheet 6 is sandwiched between the core material 11 and the magnetic wall 2, forming a closed magnetic circuit, which prevents leakage of the magnetic lines of force of the magnet sheet 6 and increases the magnetic flux density.

[0023] To mount the television 3 on the magnetic wall 2 using the article fixture 1, first, the magnetic sheets 6 on the backsides of the multiple rods 4 are magnetically attached to the magnetic wall 2, and the article fixture 1 is then mounted on the magnetic wall 2 at a desired height.

[0024] Next, as shown in Fig. 4, two upper and lower locking hooks 9a facing rearward on two left and right brackets 9 (the right bracket is not shown) that are screwed to the back of the television 3 (screws not shown) are locked from above into two upper and lower locking holes 12 in the left and right core members 11 through slits 10 in the rod-shaped bodies 4 spaced apart from each other. This allows the television 3 to be supported by the rod-shaped bodies 4 and attached to the magnetic wall 2 via the article fixture 1. Note that by removing the upper and lower caps 8 of one of the rod-shaped bodies 4 on the left or right, the power cord, antenna cord, etc. of the television 3 can be housed within the hollow portion of the rod-shaped body 4 for neat wiring.

[0025] When the article fixture 1 is attached to the magnetic wall 2 in this manner, the magnetic sheets 6 affixed to the rear surfaces of the multiple rod-shaped members 4 on the left and right sides are magnetically attached to the magnetic wall 2 over a wide magnetic area, allowing the article fixture 1 to be attached to the magnetic wall 2 with a strong magnetic force in response to a downward load. Therefore, even if a heavy television 3 is supported by the article fixture 1, there is no risk of it shifting position. Note that if the mounting height of the television 3 is to be changed, the bracket 9 can be fastened by appropriately selecting the positions of the upper and lower locking holes 12. Furthermore, if a large television 3 is to be attached, multiple upper and lower brackets 9 can be fixed to the rear surface of the television 3, and their locking hooks 9a can be fastened to the locking holes 12 spaced apart from each other at the top and bottom.

[0026] When removing the article fixture 1 from the magnetic wall 2, as shown in Figure 5(a), first lift the rod-shaped member 4 at the left end (or the right end) towards you. At this time, because the rod-shaped member 4 adjacent to the right is connected by a bendable connecting portion 5, only the rod-shaped member 4 at the left end can be lifted while bending the connecting portion 5, and the magnetic sheet 6 on its back surface can be easily peeled off from the magnetic wall 2.

[0027] Next, as shown in Figure 5(b), when the rod-shaped body 4 at the left end is pulled further forward, the right end of the convex curved surface comes into contact with the left end of the convex curved surface of the adjacent rod-shaped body 4, causing the magnetic sheet 6 of the rod-shaped body 4 adjacent to the right to be peeled off from the magnetic wall 2. In this way, by peeling the magnetic sheets 6 from the magnetic wall 2 one by one in order, starting from the left end, the article fixture 1 can be easily removed from the magnetic wall 2. Note that, because the opposing portions of the multiple rod-shaped bodies 4 are connected to each other by connecting parts 5 that can be bent in the thickness direction, the removed article fixture 1 can be folded into a roll. Furthermore, the curved surface of one adjacent rod-shaped body 4 on the left and right may be in contact with the center of the curved surface of the other rod-shaped body 4, or the center of the curved surface of one or the other rod-shaped body 4 with the end of the curved surface of one or the other rod-shaped body 4.In either case, the rod-shaped bodies 4 can be easily pulled apart one by one with little force using the principle of leverage.

[0028] As described above, in the article fixture 1 according to the first embodiment, the magnetic sheet 6 fixed to the rear surfaces of the plurality of rod-shaped bodies 4 is magnetically attached to the magnetic wall 2, thereby increasing the overall magnetic attachment area of ​​the magnetic sheet 6. As a result, the article fixture 1 can be attached to the magnetic wall 2 with a strong magnetic force against a downward load, and even if a heavy television 3 is attached to the article fixture 1, there is no risk of it being displaced.

[0029] Furthermore, because the opposing portions of the multiple left and right rods 4 are connected to each other by connecting portions 5 that can be bent in the thickness direction, when removing the article fixture 1 from the magnetic wall 2, the magnetic sheets 6 of the rods 4 at either the left or right end can be peeled off one by one from the magnetic wall 2. Therefore, even an article fixture 1 with a strong magnetic force can be easily removed from the magnetic wall 2 and its mounting position changed. Moreover, because the connecting portions 5 are continuous in the vertical direction, the connection strength between the rods 4 is strong, preventing each rod 4 from shifting downward due to the weight of the television 3.

[0030] Furthermore, the rod-shaped body 4 is formed hollow from synthetic resin material, and a high-strength core material 11 made of a steel-based material is housed inside along the vertical direction, so that the rod-shaped body 4 can be made lightweight while having high bending strength.

[0031] Furthermore, the core material 11 is provided with locking holes 12 into which the brackets 9 for mounting the television 3 are locked, and the core material 11 can support the weight of the television 3, thereby increasing the support strength of the television 3 on the rod-shaped body 4. Moreover, since multiple locking holes 12 are provided in the vertical direction, the heavy television 3 can be stably supported and the mounting height of the television 3 can be changed.

[0032] Furthermore, core material 11 made of a ferromagnetic material is housed inside rod-shaped body 4 so as to be adjacent to magnet sheet 6 and protrude laterally from both the left and right ends of magnet sheet 6, so that magnet sheet 6 is sandwiched between core material 11 and magnetic wall 2 to form a closed magnetic circuit, preventing leakage of the magnetic field lines of magnet sheet 6 and increasing the magnetic flux density. As a result, the yoke effect of core material 11 concentrates the magnetic flux of magnet sheet 6 on magnetic wall 2, allowing article fixture 1 to be attached to magnetic wall 2 with a strong magnetic attraction. Furthermore, core material 11 made of a ferromagnetic material prevents leakage of the magnetic field lines of magnet sheet 6, so there is no risk of magnetic effects on the television. [Example]

[0033] An article fixture 1 according to a second embodiment will be described with reference to Fig. 6. Note that components that are the same as those in the first embodiment are given the same reference numerals, and duplicated descriptions will be omitted. The article fixture 1 of the second embodiment has the same structure as in the first embodiment, with the locking hooks 13a, 13a of shelf support brackets 13, 13 locked into the locking holes 12 (not shown in this embodiment) of the left and right core members 11, and a shelf 14, which is an article, is supported by the top surfaces of the shelf support brackets 13, 13 and fixed from below with screws (not shown). Using such a shelf support bracket 13, the shelf 14 can be attached to the article fixture 1 that is magnetically attached to the magnetic wall 2. [Example]

[0034] 7 shows a longitudinal sectional plan view of the essential parts of the article fixture 1 according to Example 3, in which a plurality of upper and lower screw insertion holes 15 are formed in the center of the bent portion of the core material 11, and nuts 16, which are the parts to be attached, are pre-fixed by welding to the back surface opposite these screw insertion holes 15. A fastener (mounting member) 17 with a large head, such as a round head screw or a flat head screw, is threaded onto one or more of the upper and lower nuts 16, with its head protruding forward from the front wall 4b, through the screw insertion holes 15 formed in the front wall 4b of the rod-shaped body 4 and the core material 11, allowing a picture, clock, or the like to be hung on the fastener 17 and attached to the article fixture 1. Furthermore, if such an article fixture 1 is attached to a magnetic wall 2 in the kitchen, cooking utensils such as frying pans and pots can also be hung on the fastener 17 and attached.

[0035] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and additions and modifications within the scope of the present invention are also included in the present invention.

[0036] For example, in the above embodiment, the rod-shaped body 4 is made of synthetic resin material, but it may also be made of non-magnetic material such as aluminum-based material or wood, and the front surface may not be a convex curved surface but a flat vertical surface.

[0037] In the above embodiment, the rod-shaped body 4 is formed to be hollow, but it may also be formed to be solid.

[0038] Furthermore, in the above embodiment, the core material 11 is made of a steel-based material, which is a ferromagnetic material, but it may also be made of a nickel-based or cobalt-based material, which is also a ferromagnetic material.

[0039] Furthermore, in the above embodiment, the magnet sheet 6 is fixed to the rear surface of the rod-shaped body 4 with an adhesive, but it is also possible to fix it to the rear surface of the rod-shaped body 4 with screws. [Explanation of symbols]
