Description

      The present invention relates to a daily necessities for attaching a hanging hook to a magnet case joined to a metal outer plate or the like of a refrigerator or a washing machine by a magnetizing force of a magnet and suspending a household item or the like on the magnet case.

      In the conventional one, the operation member for removal is provided separately from the hanging hook so that it can be easily removed when removing the magnet case, and the magnet is fixed with screws, and the overall shape becomes large. There were problems such as an increase in the number of parts and high costs.

JP 2006-133675 A

The present invention has been made in view of the above circumstances. The purpose of the present invention is to remove the magnet case easily by operating a hanging hook without providing a separate operation member when removing the magnet case. Thus, without using a magnet fixing screw, the rotating shaft of the hook is fixed by penetrating the magnet case and cover to minimize the number of parts and provide a compact and low-cost product. .

(1) The magnetic attachment of the magnet should be easily removed by operating the hanging hook without providing a separate operating member for removal.
(2) Fix the magnet with other functions without using the magnet fixing screw.

(1) For the magnetic attachment of the magnet, a release cam is provided on the rotating shaft of the hanging hook without providing a separate operation member, and the magnetic attachment of the magnet is peeled off by rotating the hook.
(2) Fix the rotating shaft of the hook by penetrating the magnet case and cover without using the magnet fixing screw.

(1) Since there is no separate operation member for removal, the number of parts can be reduced and the size can be reduced, and the manufacturing cost can be reduced.
(2) By passing the hook rotation shaft through the magnet case and cover, the magnet can be fixed and the case and cover can be fixed simultaneously.

Cross-sectional view of an embodiment of the present invention Longitudinal sectional view of an embodiment of the present invention Exploded perspective view of an embodiment of the present invention Side view of the embodiment of the present invention when fixed to the side Side view when using the top surface of the embodiment of the present invention Release of magnetic attachment by rotating the hook when using the top surface of the embodiment of the present invention

Examples will be described below with reference to FIGS.
2 is a longitudinal sectional view of FIG. 1, FIG. 3 is an exploded perspective view of FIG. 1, FIG. 4 is a side view when the side surface is fixed, FIG. 5 is a side view when the top surface is fixed, and FIG. The magnetic adhesion release operation by the hook rotation operation is shown.
1) Insert the magnet and 2 yoke alternately, 3) Insert the 2a yoke end face into the 3b yoke groove of the 3 case, 3) Cover the 4 case on the outside of the case, and then place one 7 axis part of the 8 hook on the 4a axis of the 4 case Insert the hole and the 3a shaft hole of the 3 case through, then pull the other 7 shaft part, widen the width between the tip of both shaft parts, and the 4a shaft hole of the other 4 case and the 3 case 3a Complete assembly by inserting through the shaft hole.
In the embodiment, three 1 magnets and four 2 yokes are used. However, it is also possible to use one 1 magnet and 2 2 yokes. In addition, although 8 hooks show examples of wire bending, metal die casting or resin molding may be used. In addition, it is preferable to coat (not shown) a reinforced resin coating or cover having a low frictional resistance so that the tip of the 6 release cam portion is not damaged by friction with the surface.

Next, how to use the embodiment will be described. Fig. 4 shows the case where the attachment surface is vertical and is attached so that the opening side of the 5 hook part is on the outside. When removing in this position, the 5 hook part rotates about 135 degrees counterclockwise as seen in Fig. 6. When the 4b stopper is touched, the state shown in Fig. 6 is reached.7 The release arm pushes the adherend surface. Lost and can be easily removed by hand.
Fig. 5 shows the case where the adherend surface is on the top surface, and the 5 hook part is attached so that it hangs down. When removed in this position, the 5 hook part is about 45 degrees counterclockwise as seen in Fig. 6. When it is rotated and hits the 4b stopper, the state shown in Fig. 6 is reached.7 The release arm pushes the adherend surface. Can be easily removed by hand.

    In recent years, magnets have been used for products with high magnetic flux density due to improved materials, and it is easy to increase the bonding strength by increasing the magnetic adhesion force, but on the other hand, it has become difficult to remove it, and another for removal Adding mechanical parts makes it an expensive product. As described above, the 8 hook function can be produced at low cost without increasing the number of parts by using the function of 8 hooks separately for “hanging” and “releasing magnetic force”. Also, 1 magnet fixing method does not use screw tightening or bonding with adhesive, etc.In this plan, 3a and 3a shaft holes are provided on the side of the case and 4 cover, and 7 shaft parts of 8 hooks are used as the shaft holes. By simply inserting it through, 1 magnet can be fixed and 3 cases and 4 covers can be fixed at the same time, which not only reduces the number of parts but also the number of assembly steps, making it possible to sell high-performance products at low cost.

1 magnet, 2 yoke, 2a yoke end, 3 case, 3a shaft hole, 3b yoke groove, 3c magnet guide, 4 cover, 4a shaft hole, 4b stopper, 5 hook, 6 release cam, 7 shaft, 8 hook (5 + 6 + 7 above)
