Description

  The present invention relates to a magnetic suspension that is used by being attracted to a wall surface or the like by using a magnetic adhesion force by a magnet.

Conventionally, as a means for attaching to a wall surface or the like, a hanging tool that uses the magnetism (attraction force) of a magnet is not damaged and is not contaminated, for example, white goods such as a refrigerator or a washing machine. Because it can be easily attached to and detached from the wall, it is easy to use and widely used. On the back of the magnetic hanger, a plate-like magnet with the front and back fixed to a yoke having a U-shaped cross section is arranged with N and S poles, and the edge of the yoke is magnetized with a magnet. Generally, a structure in which an attractive force stronger than that of a magnet is obtained by setting the magnetic field slightly higher than the surface and concentrating the magnetic lines of force on the edge surface of the yoke (see Patent Document 1).

  For example, in suspension tools such as hook-shaped hooks and towel racks, ferrite magnets are mainly used as attracting magnets, especially those using neodymium magnets with a strong magnetizing force for high loads. Is also known.

  However, in particular, the magnetic suspension for high loads as described above is advantageous in that it can stably suspend relatively heavy articles, but on the other hand, once the magnet is attracted to the wall surface, Due to its strong magnetizing force, it could not be easily removed, requiring a large force for removal, and had a problem that it was difficult. In addition, it may be forcibly pulled to damage the mounting target (wall surface) or the hanging tool itself may be damaged.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an easy-to-use magnetic suspension that can easily remove a magnetic suspension adsorbed on a wall surface or the like.

That is, the present invention according to claim 1 is a magnetic suspension device that is used by adsorbing to a wall surface or the like by using a magnetizing force of a magnet, and a magnet mounting body to which a magnet is attached, and the magnet mounting body. The suspension tool is pivotally attached to a fulcrum, and is attached to a suspension tool mounting body to which a suspension tool is attached, and the suspension tool is located above the spindle and close to the wall surface during suction. It is characterized in that it comprises a homing that for the mounting body rotatably provided.

In this configuration, when the hanging tool is lifted to the front, the hanging tool mounting body swings upward with the support shaft as a fulcrum. A force in the direction of pulling away from the wall surface acts on the magnet. Due to this force, the magnetic suspension magnetically attracted to the wall surface can be easily removed from the wall surface. In addition, when removing the hanging tool, a rubbing phenomenon does not occur between the wall pad and the wall surface, so that it is possible to avoid the inconvenience that an excessive force is applied to the wall surface during the removal to damage the wall surface.

Further, the present invention described in claim 2 is the magnetic hanger according to claim 1, wherein the homing is characterized by a cylindrical.

  In this configuration, when removing the suspending tool, the wall surface and the wall rest are in line contact, so that the force for separating the magnet from the wall surface can be obtained efficiently, and if the contact surface with the wall surface is circular, It will not damage the wall.

Further, the present invention described in claim 3 is the magnetic hanger according to claim 1 or claim 2, and the magnet mounting body and the hanger mounting body of the hanger It is characterized in that it is rotatably mounted with the mounting end as a support shaft.

  In this configuration, the shaft support structure between the magnet mounting body and the hanging tool mounting body can be simplified.

According to a fourth aspect of the present invention, in the magnetic suspension device according to any one of the first to third aspects, a slip stopper is provided on the wall contact side of the suspension device mounting body. It is characterized by.

  In this configuration, the suspension fixture mounting body can swing back and forth around the support shaft, so that when a load is applied to the suspension fixture, the slip stopper is pressed against the wall surface, increasing the frictional resistance with the wall surface. In addition, the effect of preventing the deviation of the magnetic hanger due to an excessive load is improved.

As described above, according to the present invention, the wall rest is provided on the pivotable hanging fixture mounting body, so that when the lifting device is lifted to the front, the hanging fixture mounting body swings around the support shaft. The wall pad moves and presses the wall surface. As a result, a force in the direction of pulling away from the wall surface acts on the magnet, so that even a magnetic suspension that is strongly magnetically attracted to the wall surface can be easily removed.
In addition, the homing is freely rotating relative to the hanger mounting body, and, when the shape and cylindrical shape, without applying excessive force to the wall during removal, and, hanging magnetic not hurt walls Now you can remove the brace smoothly.

  In addition, since the hanging tool mounting body can swing back and forth, when a load is applied to the hanging tool, the slip stopper is pressed against the wall surface and the friction resistance with the wall surface increases, and the magnetic hanging tool is caused by excessive load. It is possible to prevent the magnet protective sheet from becoming wrinkled or swollen along with this displacement.

  Hereinafter, an embodiment of a magnetic suspension according to the present invention will be described with reference to FIGS. Here, FIG. 1 is a front view of the magnetic suspension of the present invention, FIG. 2 is a side sectional view of the magnetic suspension, FIG. 3 is a rear view of the magnetic suspension, and FIG. It is explanatory drawing which shows removal of the magnetic suspension tool of this embodiment adsorb | sucked to the wall surface.

  As shown in FIGS. 1 to 3, the magnetic suspension 10 of the present embodiment includes a synthetic resin magnet mounting body 1 with a magnet 4 mounted on the back surface (wall side), and a lower portion of the magnet mounting body 1. The suspension is attached in a freely rotatable manner, and includes a suspension mounting body 2 made of synthetic resin to which the suspension 3 is attached, and a hook 3 used as the suspension.

  The magnet 4 is a square-plate-shaped neodymium magnet that has a stronger magnetizing force than a ferrite magnet, etc., and the front and back sides are magnetized on the N and S poles inside a yoke 5 having a U-shaped cross section. In addition, an extremely thin protective sheet 6 for preventing scratches having a thickness of about 0.1 mm is attached to the magnetized surface of the magnet 4. The protective sheet 6 is preferably a urethane sheet having excellent mechanical strength and relatively high frictional resistance. This magnet-equipped yoke 5 is bonded and fixed to an angular depression 8 provided on the back surface of the magnet mounting body 1 with an adhesive 7 such as a double-sided tape.

  The yoke 5 with magnet is configured so that a strong attracting force can be obtained by forming the edge surface somewhat higher than the magnetized surface of the magnet 4 and concentrating the generated magnetic field lines on the edge surface of the yoke 5. ing.

  A plate-like non-slip 9 is fixed to the back side of the hanging tool mounting body 2. Both are connected by fitting of a convex portion 13 provided on the hanging tool mounting main body 2 side and a concave portion 14 provided on the anti-slip 9 side.

  The non-slip 9 is made of a material (for example, Lavalon) that has elasticity and is excellent in weather resistance and wear resistance.

  The hook 3 is a V-shaped metal rod with a diameter of about 4φ bent in a square shape from the center, and both base ends thereof are bent in the horizontal direction to suspend it from the magnet mounting body 1. The support shafts 12 and 12 are used to rotatably connect the tool mounting body 2.

  The V-shaped hook 3 is disposed in the guide groove 11 provided on the surface side of the anti-slip 9 and the horizontal base end portions (support shafts 12, 12) are connected to the through holes 2 a, 2 a of the hanging tool mounting body 2. The magnet mounting body 1 and the hanging tool mounting body 2 are rotatably connected by loosely fitting into the respective through holes 1a and 1a of the magnet mounting body 1 through the hanging tool mounting body 2 with the support shaft 12. The fulcrum can swing with respect to the wall surface.

  Thus, by using the mounting end portion of the hook 3 as the support shaft 12 that rotatably connects the magnet mounting body 1 and the hanging tool mounting body 2, both shaft support structures can be simplified. Cost can be reduced.

Further, a wall pad 15 is attached to the upper end portion of the hanging tool attachment body 2 above the support shaft 12. The wall rest 15 is composed of a cylindrical member made of synthetic resin, and is provided with shaft portions 16 and 16 projecting from both ends thereof, and hanging tool attachments corresponding to the shaft portions 16 and 16 are provided. each fitting recess 17 and 17 at the site of the main body 2 is formed, by loosely fitting the shaft portion 16, 16 in the fitting recess 17, the homing 15 against the hanger mounting body 2 a freely rotating Te.

  The magnetized surface of the magnet 4, the surface of the wall pad 15, and each surface of the anti-slip 9 are configured so as to be located on substantially the same plane with respect to the wall surface 20. 20, in addition to the strong magnetic force exerted by the neodymium magnet with a yoke, the suspension fixture mounting body 2 can swing back and forth around the support shaft 12, so when a load is applied to the hook 3, The anti-slip 9 connected thereto is pressed by the wall surface 20 due to its swinging action, and the frictional resistance with the wall surface 20 is increased, so that the magnetic hanger 10 is displaced due to an excessive load, and the protective sheet 6 is liable to occur along with this. Prevents wrinkles and drowning.

  In order to remove the magnetic suspension tool 10 adsorbed to the wall surface 20, as shown in FIG. When the hook 3 is raised, the suspension fixture mounting body 2 swings upward with the support shaft 12 as a fulcrum, and the wall pad 15 presses the wall surface 20 with a predetermined moment force according to the lever principle. Thereby, the force in the direction of pulling away from the wall surface 20 acts on the magnet mounting body 1, that is, the magnet 4, and even the magnetic suspension 10 that is strongly magnetically attracted can be easily detached from the wall surface 20.

Also, the homing 15 during removal is pressed to the wall 20, because the homing 15 is freely rotating, rubbing phenomena between the homing 15 and the wall 20 is not to occur, the wall surface 20 Unreasonable power is not applied. Therefore, there is no worry of damaging the wall surface 20 during removal.
In addition, when the wall pad 15 is cylindrical, the wall pad 15 is in line contact with the wall surface 20, so that the pressing force is concentrated, and the force for separating the magnet mounting body 1 from the wall surface 20 can be obtained efficiently. Will not hurt.

  As described above, in the present embodiment, the hook is used as the suspending tool 3, but it is needless to say that the hook can be applied to a towel rack, a cloth cloth rack or the like as long as it is a wall surface mounting structure using the magnetic adhesion force of a magnet.
