Description

[Technical Field]

[0001] The present invention relates to a fixing device for fixing a decorative plate to a target surface made of a magnetic material. [Background technology]

[0002] One method for fixing decorative plates (such as pictures or tiles) to the walls of building materials is to attach an iron plate to the wall (however, if the wall is magnetic, the iron plate is not necessary) and then fix the decorative plate to the iron plate with a magnet. For example, Patent Document 1 listed below discloses a method for fixing a decorative body to a wall by the attraction between a magnet fixed to the wall inside a building and another magnet placed on the back of the decorative body with the opposite pole facing the magnet. By using a magnet to fix the decorative plate, the decorative plate can be detachably fixed to the wall.

[0003] The force that secures a decorative plate to a wall or other surface is determined by the sliding load (in this case, the force applied vertically). Typically, the sliding load is about 70% of the adhesive force (in this case, the force applied horizontally), depending on the coefficient of friction of the surface being attached. In order to secure a heavy decorative plate, a magnet with a large sliding load is required, i.e., a magnet with an adhesive force about 1.5 times larger than the sliding load. On the other hand, removing the decorative plate requires a force that is equal to the strong adhesive force, making it difficult to remove the decorative plate.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a fixing device for a decorative plate that allows for easy removal of the decorative plate without reducing the sliding load. [Means for solving the problem]

[0006] The fixing device for a decorative plate of the present invention is a fixing device for fixing a decorative plate to an attachment surface made of a magnetic material, a magnetic plate having a first main surface and a second main surface facing each other in a first direction, the decorative plate being disposed on the first main surface; a magnet fixed to the second main surface; A tension plate arranged away from the second main surface in a first direction; a spring fixed between the magnetic plate and the tension plate, When the tension plate contacts the attracted surface, the spring exerts an elastic force on the magnetic plate that resists the attracting force of the magnet.

[0007] According to this configuration, when removing the decorative plate, the adhesive force of the magnet can be reduced by the elastic force of the spring, making it possible to easily remove the decorative plate without reducing the sliding load.

[0008] In the decorative plate fixing device of the present invention, the magnet and the tension plate may not overlap in the first direction.

[0009] According to this configuration, the magnet can be brought close to the surface to be attracted, so there is no need to use a magnet with a strong attracting force, and the fixing device can be made smaller and thinner.

[0010] In the decorative plate fixing device of the present invention, the tension plate may be frame-shaped, and the magnet may be disposed within the frame of the tension plate.

[0011] With this configuration, the frame-shaped tension plate stabilizes the decorative plate when it is fixed to the surface to be attached. Also, because the tension plate surrounds the magnet, the magnet is less visible, improving the aesthetic appearance of the decorative plate when it is fixed to the surface to be attached.

[0012] In the decorative plate fixing device of the present invention, the spring may be a leaf spring, and a plurality of leaf springs may be provided.

[0013] With this configuration, the use of leaf springs allows the springs to be thinner than, for example, coil springs, and the fixing device can be made thinner. Also, by fixing the decorative plate with multiple leaf springs, the decorative plate is stabilized when fixed to the surface to be attached.

[0014] In the decorative plate fixing device of the present invention, at least a pair of the springs may be arranged at positions facing each other with the magnet in between.

[0015] This configuration makes it easy to fix the decorative plate parallel to the surface to be attached.

[0016] In the decorative plate fixing device of the present invention, the tension plate may have an outer shape smaller than the outer shape of the magnetic plate.

[0017] With this configuration, the tension plate does not get in the way, so the decorative plates can be fixed adjacent to each other on the attached surface, making it possible to decorate the entire attached surface with decorative plates without any gaps, for example.

[0018] In the decorative plate fixing device of the present invention, the magnetic plate may be rectangular, and the tension plate may be rectangular frame-shaped.

[0019] This configuration is suitable for fixing rectangular decorative plates such as pictures or tiles to the surface to be attached.

[0020] Another decorative plate fixing device of the present invention is a fixing device for fixing a decorative plate made of a magnetic material to an attachment surface made of a magnetic material, a magnet fixed to the rear surface of the decorative plate; A tension plate disposed away from the back surface of the decorative plate; a spring fixed between the back surface of the decorative plate and the tension plate; When the tension plate contacts the attracted surface, the spring exerts an elastic force on the decorative plate that resists the attracting force of the magnet.

[0021] According to this configuration, when removing the decorative plate, the adhesive force of the magnet can be reduced by the elastic force of the spring, making it possible to easily remove the decorative plate without reducing the sliding load.

[0022] In addition, the term "decorative plate" in this invention includes not only plate-shaped decorative objects such as paintings and tiles, but also thin sheet-shaped decorative objects such as wallpaper, and decorative objects made of a plate made of magnetic material and decorated (for example, by engraving or printing). [Brief explanation of the drawings]

[0023] [Figure 1] FIG. 1 is a side view showing an example of a fixing device for a decorative plate according to a first embodiment; [Figure 2] FIG. 1 is an exploded perspective view showing an example of a fixing device for a decorative plate according to a first embodiment; [Figure 3] FIG. 10 is a side view showing an example of a fixing device for a decorative plate according to a second embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, an example of an embodiment of a decorative plate fixing device of the present invention will be described with reference to the drawings.

[0025] First Embodiment FIG. 1 is a side view showing an example of a fixing device for a decorative plate according to the first embodiment. FIG. 2 is an exploded perspective view showing an example of a fixing device for a decorative plate according to the first embodiment. In this embodiment, the attached surface S to which the decorative plate 9 is fixed is arranged along the second direction D2 and the third direction D3. Although not particularly limited, the third direction D3 may be an up-down direction (vertical direction). The second direction D2 is a direction perpendicular to the third direction D3 and may be a horizontal direction. The first direction D1 is a direction perpendicular to the second direction D2 and the third direction D3 and may be a horizontal direction.

[0026] The attracted surface S is made of a magnetic material. The attracted surface S is the surface of an object to be attracted, such as an iron plate. The object to be attracted, including the attracted surface S, is fixed to a wall W, as shown in FIG.

[0027] The fixing device 1 for the decorative plate 9 includes a magnetic plate 2, a magnet 3, a tension plate 4, and a spring 5.

[0028] The magnetic plate 2 is a plate member made of a magnetic material, such as a metal, and functions as a yoke (back yoke).

[0029] The magnetic plate 2 has a first main surface 2a and a second main surface 2b that face each other in the first direction D1. Although not particularly limited, the first main surface 2a and the second main surface 2b are parallel to each other. The first main surface 2a and the second main surface 2b are arranged along the second direction D2 and the third direction D3.

[0030] The magnetic plate 2 is rectangular, although not particularly limited to this. A decorative plate 9 is disposed on a first main surface 2a of the magnetic plate 2. The decorative plate 9 is fixed to the first main surface 2a of the magnetic plate 2. The decorative plate 9 may be fixed to the magnetic plate 2 by adhesive or the like.

[0031] The decorative plate 9 is rectangular and is the same size as or larger than the magnetic plate 2. When the decorative plate 9 is relatively large (for example, 100 cm x 100 cm) or heavy, a magnet 3 with strong adhesive force is required, and therefore the fixing device 1 of the present invention is particularly useful.

[0032] The material of the decorative plate 9 may be a magnetic or non-magnetic material, and may be, for example, plywood.

[0033] The magnet 3 is fixed to the second main surface 2b of the magnetic plate 2. As a result, the magnetic plate 2 is fixed to the attracted surface S by the attractive force of the magnet 3. It is preferable that the magnet 3 contacts the attracted surface S to obtain a strong attractive force. However, the magnet 3 does not have to contact the attracted surface S. If the attractive force is too strong, it can be adjusted by attaching non-magnetic tape or the like as a spacer to the magnet 3. In this embodiment, two magnets 3 are provided. Although not particularly limited, the magnet 3 has a plate shape that is long in the second direction D2.

[0034] The magnet 3 is not particularly limited, but may be, for example, a ferrite magnet. Ferrite magnets are preferable because they are inexpensive and lightweight. However, other magnets (such as rare earth magnets) can also be used as the magnet 3 by adjusting the size and thickness of the magnet 3 and the elastic force of the spring 5.

[0035] The tension plate 4 is disposed away from the second main surface 2b of the magnetic plate 2 in the first direction D1. The tension plate 4 is, although not particularly limited to, in the shape of a rectangular frame. The magnet 3 is disposed within the frame of the tension plate 4. In other words, the magnet 3 and tension plate 4 are disposed so as not to overlap in the first direction D1.

[0036] The tension plate 4 may be made of either a magnetic or non-magnetic material. However, if the tension plate 4 is made of a magnetic material, it may affect the attractive force of the magnet 3, so it is preferable that the tension plate 4 be made of a non-magnetic material. The tension plate 4 is made of a non-magnetic metal material, for example, stainless steel. Furthermore, a surface material with a higher coefficient of friction than the surface of the tension plate 4 may be attached to the surface of the tension plate 4 that comes into contact with the attracted surface S.

[0037] The spring 5 is fixed between the magnetic plate 2 and the tension plate 4. The spring 5 is preferably a leaf spring. Leaf springs are preferable because they are inexpensive and have sufficient spring force. The spring 5 may be made of either a magnetic material or a non-magnetic material.

[0038] A plurality of springs 5 ​​are provided. It is preferable that at least one pair of springs 5 ​​are provided at positions facing each other across the magnet 3. It is particularly preferable that four springs 5 ​​are provided around the magnet 3, above, below, left, and right. Note that a spring 5 may also be provided at each of the four corners of the magnetic plate 2 and the tension plate 4.

[0039] In this embodiment, the spring 5 is a long leaf spring, and both ends are fixed to the tension plates 4, and the center is fixed to the magnetic plate 2. Both ends of the spring 5 may be fixed to the tension plates 4 by welding or the like. The center of the spring 5 may also be fixed to the magnetic plate 2 by a bolt, screw, or the like.

[0040] From the above, it is preferable that the fixing device 1 for the decorative plate 9 is a fixing device 1 for fixing the decorative plate 9 to an attached surface S made of a magnetic material, and comprises a magnetic plate 2 having a first main surface 2a and a second main surface 2b facing in a first direction D1, with the decorative plate 9 arranged on the first main surface 2a or the first main surface 2a becoming the decorative plate 9 (in this embodiment, the decorative plate 9 is arranged on the first main surface 2a), a magnet 3 fixed to the second main surface 2b, a tension plate 4 arranged away from the second main surface 2b in the first direction D1, and a spring 5 fixed between the magnetic plate 2 and the tension plate 4, and that when the tension plate 4 abuts against the attached surface S, the spring 5 exerts an elastic force on the magnetic plate 2 that resists the adhesive force of the magnet 3.

[0041] The force that secures the decorative plate 9 and magnetic plate 2 to the attracted surface S is due to the sliding load of the magnet 3. The sliding load is the load at which the decorative plate 9 and magnetic plate 2, which have been attracted to the attracted surface S by the magnet 3, begin to slide when a force parallel to the attracted surface S (here, a force applied vertically) is applied. Typically, the sliding load is approximately 70% of the adhesive force (here, a force applied horizontally), depending on the friction coefficient of the attracted surface S. Therefore, to secure a heavy decorative plate 9, a magnet 3 with a large sliding load, i.e., a magnet 3 with an adhesive force approximately 1.5 times larger than the sliding load, is required. On the other hand, removing the decorative plate 9 requires a force that counteracts this strong adhesive force. According to the present invention, the adhesive force is reduced using the spring 5, making it possible to easily remove the decorative plate 9 without reducing the sliding load.

[0042] Second Embodiment The second embodiment has the same configuration as the first embodiment except for the configuration described below, so the commonalities will be omitted and differences will be mainly described. Note that in the second embodiment, elements having substantially the same configuration or substantially the same function (action) as the parts described in the first embodiment will be shown, and their description will not be repeated.

[0043] FIG. 3 is a side view showing an example of a fixing device for a decorative plate according to the second embodiment. If the decorative plate 9 is made of a magnetic material, the magnetic plate 2 is not necessarily required. The fixing device 1 for a decorative plate 9 according to the second embodiment includes a magnet 3 fixed to the back surface of the decorative plate 9, a tension plate 4 positioned away from the back surface of the decorative plate 9, and a spring 5 fixed between the back surface of the decorative plate 9 and the tension plate 4, and when the tension plate 4 abuts against the attracting surface S, the spring 5 exerts an elastic force on the decorative plate 9 that resists the attracting force of the magnet 3. Here, the back surface of the decorative plate 9 refers to the surface opposite to the decorated surface.

[0044] The fixing device 1 for a decorative plate 9 is not limited to the configuration of the above-described embodiment, nor is it limited to the above-described effects. Furthermore, it goes without saying that various modifications can be made to the fixing device 1 for a decorative plate 9 without departing from the spirit of the present invention. For example, the configurations and methods of the above-described embodiments may be arbitrarily adopted and combined, and further, it goes without saying that one or more of the configurations and methods of the various modified examples described below may be arbitrarily selected and adopted in the configurations and methods of the above-described embodiments.

[0045] (1) In the fixing device 1 for the decorative plate 9 according to the above embodiment, the magnet 3 and the tension plate 4 do not overlap in the first direction D1. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, the magnet 3 and the tension plate 4 may be configured to at least partially overlap in the first direction D1.

[0046] (2) In the fixing device 1 for the decorative plate 9 according to the above embodiment, the tension plate 4 is frame-shaped, and the magnet 3 is arranged within the frame of the tension plate 4. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, the tension plate 4 may be rectangular, the spring 5 may be arranged in the center of the tension plate 4, and the magnet 3 may be arranged around the spring 5.

[0047] (3) In the fixing device 1 for the decorative plate 9 according to the above embodiment, the spring 5 is a leaf spring, and a plurality of springs are provided. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, the spring 5 may be a coil spring. However, since a coil spring is thick, a leaf spring is preferable.

[0048] (4) In the fixing device 1 for the decorative plate 9 according to the above embodiment, at least one pair of springs 5 ​​are arranged in positions facing each other across the magnet 3. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, only one spring 5 may be arranged in the center of the tension plate 4.

[0049] (5) In the fixing device 1 for the decorative plate 9 according to the above embodiment, the outer shape of the tension plate 4 is smaller than the outer shape of the magnetic plate 2. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, the outer shape of the tension plate 4 may be the same as or larger than the outer shape of the magnetic plate 2.

[0050] (6) In the fixing device 1 for the decorative plate 9 according to the above embodiment, the magnetic plate 2 is rectangular, and the tension plate 4 is a rectangular frame. However, the fixing device 1 for the decorative plate 9 is not limited to this configuration. For example, the tension plate 4 may be a circular or elliptical frame. Furthermore, the outer shapes of the magnetic plate 2 and the tension plate 4 may be the same or different.

[0051] (7) In the above embodiment, a single decorative plate 9 is fixed to the attracted surface S. However, multiple decorative plates 9 may also be fixed to the attracted surface S. In this case, by making the outer shape of the tension plate 4 smaller than the outer shape of the magnetic plate 2, the tension plate 4 does not get in the way, and the decorative plates 9 can be fixed adjacent to each other to the attracted surface S. This makes it possible to decorate the entire surface S with decorative plates 9 without any gaps. Furthermore, the decorative plate may be made up of a single plate, or may be made up of multiple plates, i.e., multiple decorative plates are arranged on a single magnetic plate.
