Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is used by adsorbing a magnet to something made of magnetic material, such as a steel cabinet, desk, or housing for electric appliances, and suspending an article from a hook provided in a case that holds the magnet. Regarding the hook with a magnet.

[0002]

[Prior Art]

 As shown in the cross-sectional view of FIG. 3, the hook body 1 with a magnet has a case 2 having a concave cross-section formed by a non-magnetic material such as synthetic resin, and a concave cross-section provided in the concave part of the case 2 as well. It is mainly composed of a yoke 3 and a magnet 4 provided in a state of being magnetically coupled to the yoke 3. The hook 5 is swingably suspended by a protrusion 7 formed on one surface of the case 2, that is, the front surface 6 in this case, so that the hook 5 is moved along the front surface 6 of the case 2. It can swing about 180 degrees.

The hook 5 is composed of a hanging portion 8 hanging from the protrusion 7 as it is, and a bent portion 9 that is bent from the hanging portion 8 so that an article can be hung. Is hooked on the bottom portion 10 of the bent portion 9 and suspended.

By the way, the suspension load of the hook body 1 having such a shape is determined by the magnetic force of the magnet and the moment applied from the hook 5 to the case. That is, in order to increase the suspension load, the magnetic force of the magnet 4 may be increased or the moment of the hook 5 may be decreased. However, increasing the magnetic force of the magnet 4 means increasing the size of the magnet 4, and the magnet becomes thicker and the moment with respect to the hook 5 increases.

[0005]

[Problems to be solved by the device]

 From these facts, it is understood that the momentum by the hook 5 must be reduced in order to increase the suspension load. Therefore, in order to reduce the moment, it is preferable that the bottom portion 10 of the bent portion 9 of the hook 5 is as close as possible to the wall surface 11 on which the yoke 3 is adsorbed. Therefore, even if the hanging portion 8 of the hook 5 is bent so that the bottom portion 10 is located inside the front surface 6 of the case 2, depending on the thickness or size of the article when suspended. The hook 5 is displaced to the front side, and the actual hanging position is often the conventional position shown in FIG. 3 or a position farther from the wall surface 11 than that. In such a situation, the same hanging load or comb as in the past can only obtain a smaller hanging load, which causes a problem in practical use.

The present invention has been made in view of the above technical background, and an object thereof is to provide a hook with a magnet capable of increasing the suspension limit load even if the size of the magnet is the same. To do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a case in which a hook is swingably provided on one surface, a magnet provided on the other surface of the case, and a yoke magnetically coupled to the magnet. In a hook with a magnet, which has at least the yoke part in contact with a magnetic substance to magnetically adsorb it and hangs the product on the hook, the part of the hook on which the product is hung is attracted at least more than the case thickness. It is equipped with locking means that can enter the wall surface and regulate the position of the hook.

[0008]

[Action]

 According to the above-mentioned means, the yoke of the hook main body is attracted to the wall surface made of a magnetic material, the article is hung and hung from the hook, and the position of the hook is regulated by the locking means so as not to be separated from the wall surface. The hanging part of the hook is always located close to the wall from the front side of the case. As a result, the moment applied from the hook to the case is reduced, and the suspension load is increased accordingly.

[0009]

【Example】

 An embodiment of the present invention shown in the drawings will be described below. In the following description, substantially the same constituent members as those in the above-described conventional example are designated by the same reference numerals, and duplicated description will be omitted.

FIG. 1 is a perspective view of a hook with a magnet according to this embodiment, and FIG. 2 is a cross-sectional view showing its attached state. In these figures, the hook 5 is attached to the lower end of the vertical portion 13 of the substantially T-shaped support shaft 12. Both ends of the horizontal portion 14 of the support shaft 12 are rotatably supported by a pair of protrusions 15 and 15 provided at intervals on the front surface 6 of the case 2. The hook 5 is formed by bending so that the bottom portion 10 corresponding to the lower end of the hanging portion 8 comes from the front surface 6 of the case 2 to a position close to the wall surface 11.

Further, as a locking means so as to prevent the hook 5 from swinging and moving forward from the front side surface 6 of the case 2 when suspending an article, a protrusion 16 is provided on the back surface of the horizontal portion 14 of the support shaft 12. A known snap-fit mechanism is provided on the surface 6 on the front side, and a recess 17 into which the protrusion 16 is detachably press-fitted is provided. With this, when the support shaft 12 is pressed against the front surface 6 after being suspended, the projection 16 of the snap-fit mechanism is elastically fitted into the recess 17 formed in the front surface 6 and locked. It Other than the above, all the components not particularly described are constructed in the same manner as in the conventional example of FIG.

With such a configuration, in the conventional example of FIG. 3, when the bottom portion 10 is separated from the wall surface 13 by 13 mm, the suspension limit load, in other words, the holding force is 1.97 Kg. In the case of, when the bottom is 5 mm apart, it increases to 2.89 kg. It can be seen that this clearly improves the holding force by reducing the moment.

[0013]

EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention configured as described above, the hanging portion of the hook swingably provided on the front side surface of the case is attached to the suction side. The moment applied to the case is reduced because it is brought closer to the surface and does not move to the front side, and the suspension limit load can be increased accordingly.
