Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device that uses magnetic force to stop the opening/closing door of a small container.

[Prior art]

FIG. 2 is an overall perspective view showing a state in which the door is open, and FIG. 3a is a perspective view showing a magnet piece fixed to a panel. FIG. 3b is a side sectional view when the door is closed and the suction member is suctioned.

As shown in FIG. 2, the case 1 has a hexahedron with an opening on its front side. A panel 2 made of a non-magnetic material is provided on the front side of the case 1, and near the center of the upper part of the panel 2, for example, a magnet piece 5 is attached with an adhesive 6. The panel 2 and the opening/closing door 3 are engaged with each other via a hinge 7 at the lower part,
For example, an iron plate 4 is fixed near the upper center of the inside of the opening/closing door 3 in correspondence with the magnet piece 5, and when the opening/closing door is closed, the magnet piece 5 and the iron plate 4 are attracted to each other and the opening/closing door 3 is closed. When opening, it is configured to open against the attraction force of the magnet piece 5 and the iron plate 4.

[Problem that the invention attempts to solve]

In the prior art, the magnet piece 5 directly receives the impact force when the opening/closing door 3 is closed, and there is a drawback that the magnet piece 5 may crack or chip because it is not configured to alleviate the impact force. The purpose of the present invention is to eliminate these drawbacks of the prior art.

[Means for solving problems]

This invention has a locking structure for an opening/closing door in which a pair of magnetic adsorption members is attached to the opening/closing door and a panel, and when the opening/closing door is closed, the opening/closing door is held to the panel by the mutual adsorption force of the pair of magnetic adsorption members. At least one of the opening/closing door and the panel is hollowed out in three directions around the area where the magnetic adsorption member is attached to form a tongue-shaped groove.

(Function) At least one of the opening/closing door and the panel has a tongue-shaped part to which the magnetic attraction member is attached, and the impact force applied to the magnetic attraction member when the opening/closing door is closed is absorbed and alleviated by the deformation of the tongue. be done.

(Example) Figures 1a and b show examples of this invention, and the same members as those shown in Figures 2 and 3 a and b as conventional examples are given the same reference numerals. A detailed explanation will be omitted.

In Figures 1a and b, a magnet piece 5 is fixed to the panel 2 as one magnetic attraction member with an adhesive 6, and the upper part and both left and right sides of the part where the magnet piece 5 is attached are continuous in a U-shape. It is hollowed out with a U-shaped groove 2b. Therefore, the portion to which the magnet piece 5 is attached forms an upwardly directed tongue piece 2a.

In such a structure, the open/close door 3
When it is rotated to the right from the position shown by the two-dot chain line in Fig. 1b and closed, the iron plate 4 attached to the opening/closing door 3 as the other attraction part is attracted to the magnet piece 5 and collides with the magnet piece 5. do. At this time, the tongue piece 2a is the magnet piece 5
The stem is elastically deformed to the right as shown by the two-dot chain line in FIG. Then, the tongue 2a absorbs the impact force by deforming, and after deforming to a position where the absorbed and alleviated impact force and the bending resistance of the tongue 2a are balanced, the tongue 2a returns to its original state due to its own elasticity. The magnet piece 5 attracts the iron plate 4 and the opening/closing door 3 is held on the panel 2.

In the above embodiment, the U-shaped groove 2b is provided on the panel 2, but it may be provided on the door 3 instead of the panel 2, or may be provided on both the panel 2 and the door 3. Alternatively, a magnet piece 5 may be attached to the opening/closing door 3, and an iron plate 4 may be attached to the panel 2. Furthermore, magnet pieces may be used for both of the attraction members.

〔effect〕

Since the impact force applied to the magnet piece 5 can be reduced compared to conventional products, cracking and chipping of the magnet piece 5 can be eliminated.
