JPS5837809Y2 - Hinge device for various containers - Google Patents

Description

[Detailed explanation of the idea] This invention relates to hinge devices for various containers.

Conventionally, hinges between the main body and lid of various containers have been formed by fitting a convex part of the lid into a concave part of the main body and inserting a mandrel, and either the mandrel is exposed to the outside and can be pulled out. However, there were drawbacks such as the mandrel being bent due to careless tension, making it unusable.

This invention is proposed to eliminate the drawbacks of these conventional products, and its purpose is to utilize the attraction effect of magnets to connect the main body and lid to the notch of the main body. The hinge part can be constructed simply by fitting and inserting the protruding part of the lid body, and the hinge part can be assembled easily and quickly. , a notch 6 at the center or both sides of one end of the main body 2.
A protrusion 7 that fits into the notch 6 of the main body 2 is provided in the center or both sides of one end of the lid 3 so that the notch 6 of the main body 2 and the protrusion 7 of the lid 3 are connected. Each sliding surface 4゜4'...
Disc-shaped magnets 5, 5', etc. are fitted concentrically in..., and the magnets 5, 5',... maintain the attracted state by their traction action. At the same time, the hinge part is rotatably supported.

This invention has the above-mentioned configuration, and includes a sliding surface 4 between the notch 6 of the main body 2 and the protrusion 7 of the lid 3;
In order to fit the magnets 5, 5'... into 4'..., the main body 2 and the lid 3 must be separated,
A magnet 5,
5'..., and it is important to manufacture these so that they are concentric when combined.

The main body 2 and the lid 3 configured as described above can be assembled by simply fitting the protrusion 7 of the lid 3 into the notch 6 of the main body 2, and each sliding surface 4, 4', . . . is pivotally supported by the traction and adsorption of magnets 5, 5' .
When opening and closing, the attraction surfaces of the magnets 5, 5', etc. slide, but the two do not come apart, and are in the same state as if they were pivotally supported.

Therefore, there is no need for a stem like in the conventional hinge, 1.
It can be pivoted reliably, and especially when it is necessary to remove the lid 3, it can be done by simply pulling the lid 3 strongly, and it is also easy to fit it again.

This idea uses the traction and attraction force of magnets 5, 5', etc. to form the hinge part between the main body 2 and the lid 3 as shown in the above figure, so it overcomes the drawbacks of the conventional mandrel. It is easy to remove and manufacture, and it is also easy to put on and take off the lid, which has extremely significant effects.

Claims (1)

[Scope of utility model registration request] In the case where magnets 5, 5' are used in the hinge part of the container, one side of the main body 2 of the container 1 is cut out 6 to form a sliding surface 4.4', and the sliding surface 4, The magnet 5° 5' is embedded in the lid 3, and a protrusion 7 is provided in the lid 3 to be fitted in alignment with the sliding surfaces 4, 4' of the notch 6. A hinge device for various containers, characterized in that magnets 5, 5' are also embedded in both sides of the protrusion 7, opposite to the sliding surfaces 4, 4'.
