Abstract

PROBLEM TO BE SOLVED: To materialize a wall hook attached by the attractive power of a magnet to the wall of a magnetic body, which can hang a heavy object without damaging the wall surface and which is not a simple mechanical hook but arouses a playful mood making anyone feel like hanging down from it by just looking at it.SOLUTION: In the wall hook that is attached by the attractive power of a magnet under the present invention, a part where the wall hook is in contact with the wall surface is covered by a material having a large surface friction coefficient, with an installation structure arranged in a part lower than the load point of the hook, thereby making it possible to hang a heavy hanging object. Also, by the adoption of an angle variable mechanism of the hook part and by the consideration of the position and the shape of the magnet installation, there is used solution means in which the hook is hardly separable in normal use but is easily removable in position change.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a wall-hanging hook that is attached to a magnetic wall surface such as a steel plate, is sealed with a strong permanent magnet on the back surface, and is attached using a magnetic attractive force.

  Conventionally, when attaching a hook to a wall surface of a magnetic body, an attachment hole or a screw tap must be provided in a hard wall surface, and it is very difficult for a general user to perform installation work.

  In addition, after the attachment, the attachment work must be performed again to move the position, and the attachment hole remains after the movement.

  Therefore, a wall-hanging hook is used that is magnetically attracted and held by a permanent magnet on the wall surface of a magnetic body and suspends clothing or small items on a hook attached to the permanent magnet or a case that houses the permanent magnet. In this case, if the magnet and the yoke for concentrating the magnetic force are exposed and attracted to the wall surface, the attraction force is maximized. However, since the coefficient of friction of the magnet and the yoke surface is not large, the wall-hanging hook may slip down and damage the wall surface due to the weight of the load on the hook.

  In order to solve such problems, Patent Document 1 discloses a technical idea that covers the surface of a permanent magnet with a thin film having a large coefficient of friction such as rubber and urethane, and prevents the wall surface from being scratched while preventing sliding.

  However, as shown in FIG. 4 of Patent Document 1, when the hook is separated from the wall surface, the load point of the suspended object suspended from the hook is separated from the wall surface, and the force to pull the permanent magnet away from the wall surface becomes strong. End up.

  Moreover, the shape of the hook is inorganic, and it cannot be said that sufficient consideration is given in terms of interior decoration and comfort.

  Furthermore, in recent years, with the development of permanent magnets, magnets having a very strong magnetic force such as neodymium magnets have been developed, and the holding power of the hooks has been greatly increased, but conversely it may be difficult to peel off.

Japanese Utility Model Publication No. 6-26655

  As mentioned above, many wall-mounted hooks that are attached to a magnetic wall such as a steel plate, enclose a strong permanent magnet on the back side, and are attached using magnetic attraction force are practically used and have considerations such as decorativeness and comfort. There wasn't.

  In recent years, extremely strong permanent magnets such as neodymium magnets have become available, and new problems have arisen that the wall-hanging hooks using these magnets are damaged and are difficult to be removed from the wall surface.

  Even if the permanent magnet becomes stronger, if the load point of the hook part moves away from the wall surface, the moment for peeling the permanent magnet from the wall surface increases, and the weight of the suspended object suspended on the hook part increases. It will be restricted.

  In order to solve the above-described problems, the arm-type wall hanging hook according to the present invention has a hook portion that is similar to an anime or cartoon character, and has a little humor or a decorative element compared to a conventional inorganic hook. Is added. Further, a thin film having a high frictional resistance such as silicon rubber is interposed in a portion where the permanent magnet or the yoke contacts the wall surface so as not to damage the wall surface.

  In addition, a hook mounting structure is placed below the hook load point so that no moment is generated in the direction in which the hook is peeled off the wall surface, and the hook is mounted according to the weight of the suspended object suspended from the hook. The moment that presses the part against the wall surface prevents the permanent magnet from being peeled off.

  Although it is good that it is difficult to peel off by the weight of the suspended object by the above solution, there is a problem that it is difficult to peel off when it is desired to change the mounting position of the hook. As a means for solving this problem, the permanent magnet can be separated from the wall surface by making a screw hole in the permanent magnet and screwing the screw there.

  As another method, the permanent magnet is disposed above the hook mounting portion, and the shape of the permanent magnet is wider than the lower side. Furthermore, a protrusion or a depression is formed in the lower part of the structure, and this part can be lifted from the wall surface with a finger. By pulling the hook mounting portion, the arm type of the present invention can be easily obtained by the lever principle. The wall hook can be peeled off the wall surface.

  By using the arm-type wall-hanging hook of the present invention, the arm protruding from the wall is fun, especially for children, because it is interesting and does not throw a hat or bag, it is hung on the hook, so that it can be used for disciplined arrangement Demonstrate the effect.

  Of course, the hook can be attached without damaging the wall surface by interposing a thin film having a large frictional resistance such as silicon rubber between the arm type including the permanent magnet and the wall surface.

  In addition, a heavier suspended object is suspended from the hook by replacing the weight of the suspended object related to the hook with a moment in the direction of pressing the wall surface by providing a structure below the hook load point. Can do.

  Furthermore, by grasping and lifting the lower part of the structure with a finger, the wall-hanging hook can be peeled off from the wall surface relatively easily by the lever principle.

  While the hook can be easily peeled off from the wall surface by the lever principle as described above, the hook can be easily peeled off from the wall surface by providing a through screw in the permanent magnet portion and rotating the screw to push the wall surface.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and the range necessary for the description of the relevant part of the present invention will be mainly described. According to a known technique.

  FIG. 1 is a schematic view of an arm-type wall hanging hook according to an embodiment of the present invention, including a hook attachment portion including a part of a torso from a human shoulder portion, a hook portion and a hook by an upper arm and an arm whose elbow is bent. It consists of a permanent magnet embedded in the mounting part. FIG. 1 a is an example of a muscular arm that gives a sense of security that it is possible to suspend a suspended object with an extremely strong force. FIG. 1b is an example of an arm that imitates the arm of a manga or anime character, and can give a little humor and playfulness to those who are familiar with manga and anime.

  FIG. 2 shows an example of a normal wall-hanging hook. As shown in FIG. 4 of Patent Document 1, when the hook load point 24 of the normal wall-hanging hook 20 is separated from the wall surface, the hook mounting portion 21 is attached by a moment with respect to the lower end 26. The force which tears off a part will be produced.

  FIG. 3 is a schematic view showing a cross-sectional view of one example 30 of the arm-type wall hanging hook according to the embodiment of the present invention. A hook-type hook 32 is integrated with the hook-type hook 32, and the portion where the mounting portion 31 and the magnet 33 embedded in the mounting portion are in contact with the wall surface 39 is made of a material having a large surface friction coefficient such as silicon rubber. 34. In the example of FIG. 3, the magnet 33 is entirely coated with the material 34, but it is needless to say that only the portion in contact with the wall surface 39 may be coated.

  In addition, a lower structure 36 simulating the lower part of the body that supports the arm below the vertical position 37 from the load point 35 of the arm type hook 32 to the wall surface 39 is integrated with the hook attachment part 31. In the case of such a structure, the suspended load 38 applied to the arm-type hook portion 32 becomes a moment for pressing the lower portion of the hook attachment portion lower structure 36 against the wall surface 39. For this reason, coupled with the material 34 having a large surface friction coefficient, it becomes difficult for the arm-type wall-hanging hook to fall off or peel off, and a suspended object having a weight greater than that of the conventional one can be suspended.

  In the wall hanging hook of the present invention, the angle of the elbow of the arm type hook can be changed. FIG. 4 (a) shows an example. The elbow portion is divided into two parts, the elbow 41a has a screw hole 42a at the elbow fulcrum, and a plurality of pin holes are provided at specific angles on the circumference around the screw hole 42a. 43a is opened. A screw hole 42b corresponding to the screw hole 42a is formed in the elbow fulcrum portion of the other elbow portion 41b, and a pin hole 43b is formed at a distance equal to the circumference from the screw hole 42b.

  The arm-shaped hook is assembled by placing the other elbow 41b on one elbow 41a so that the screw holes 42a and 42b coincide with each other, connecting them with screws 44, and inserting a pin or screw 45 to change the angle of the arm. Can be set arbitrarily.

  FIG. 4B is another example of changing the elbow angle of the arm type hook. Similarly to the above example, the arm type hook is divided into two at the elbow portion, and a screw hole is formed at the center of one elbow 46a. 47a is opened, and a notch 48a is provided in the shape of a saw blade radially around the screw hole 47a, and the other elbow 46b is provided with a saw-tooth notch 48b opposite to 48a around the screw hole 47b. , 46b and can be fixed at an arbitrary angle by a screw 49.

  FIGS. 4A and 4B show examples of the arm angle setting method of the arm-type wall hanging hook according to the present invention. In addition to the above two examples, a method of changing the elbow angle by a similar method is conceivable. All of these are included in the technical idea of the present invention.

  As described above, by providing the hook attachment portion structure below the load point of the hook portion, the hook attachment portion is difficult to peel off. However, if the permanent magnet is vertically long, it will be easily peeled off when a lateral force is applied to the hook portion. Therefore, in the present invention 50, as shown in FIG. 5, an example in which an inverted triangular permanent magnet 52 is embedded above the hook attachment portion 51 and downward from the shoulder portion having a wide width is shown.

  With such a configuration, even if a lateral force 54 is applied to the hook portion 53 by the wide upper side portion of the permanent magnet 52, it is difficult to peel off. The reason why a permanent magnet having a wide upper side such as an inverted triangle and a narrow lower width is provided above the hook mounting portion will be described later.

  Up to this point, a method has been described in which the hook mounting portion is less likely to peel off from the wall surface. However, coupled with the recent use of strong magnets, there are cases where it becomes difficult to peel off when it is desired to peel off. FIG. 6 is a cross-sectional view showing a method of peeling off the strong magnet. The magnet 63 is easily separated from the wall surface 66 by providing a screw hole 64 in the magnet 63 and screwing a screw 65 fitted in the screw hole 64. Can do. Of course, the tip of the screw 65 is covered with silicon rubber or the like so as not to damage the wall surface 66.

  Furthermore, FIG. 7 is an explanatory view of another technical method for easily peeling off the strong magnet as described above. As described above with reference to FIG. 5, since the permanent magnet 72 is mounted above the hook mounting portion 71, if the lower portion of the hook mounting portion is lifted in the direction of the arrow 74 in FIG. It becomes easy. Further, if the shape of the permanent magnet 72 is wide like the inverted triangle and the width of the upper side is wide and the lower part is narrowed, the permanent magnet 72 can be more easily peeled off against the force that lifts the lower part of the hook mounting portion.

  In FIG. 7, the example which attached the protrusion 73 so that it was easy to lift to the lower part of a hook attaching part is shown. Of course, you may make it easy to lift by providing a hollow instead of a protrusion. As described above, the arm-type wall hanging hook according to the structure of the present invention is difficult to slide down and strong against the force of pushing the arm-type hook sideways. It will have the characteristic that it can peel off.

  FIG. 8A shows an example in which a spring-winding wire bobbin or thin string bobbin 82 is installed inside an arm-type hook 81, and a wire hook 83 is provided on the side surface of the arm-type hook. As shown in FIG. 8b, the method of the present invention uses two arm-type wall hanging hooks shown in FIG. 8a, connects the hooks with a built-in wire or thin string 84, and hangs a small piece 85 such as a handkerchief on the wire. be able to. Of course, if you don't use a wire, you can remove the wire and wrap it around.

  The invention according to the present application is not limited to the above-described embodiment, and various modifications, expansions, substitutions, deletions, and the like are permitted within the scope of the same technical idea, all of which are as the technical idea of the present invention. It is included in the range. For example, in the above description, the permanent magnet embedded in the hook mounting portion is disclosed. However, the present invention is not limited to this, and may be a general magnet including an electromagnet, for example.

  The present invention is not only a function to hang the original suspension of the hook, but also because of its playfulness, if it is used for a wall hanging hook in a children's room or a wall hanging hook in a school, children will be happy and willing Can be used to help keep things organized.

  In addition, it is possible to hang a cloth like a handkerchief using a hook angle changing function or a built-in wire, or to hang a long object using a plurality of the wall hanging hooks of the present invention. It is possible to suspend suspended objects that were difficult to perform.

  In the above description, an example imitating a human arm has been described, but the present invention can be widely applied to animals other than humans, fictional creatures, and the like.
