Abstract

<P>PROBLEM TO BE SOLVED: To actualize a hinge device enabling to freely fix an object to be fixed onto a curved surface in a rotatable manner while using one magnet for fixing one object to be fixed including the magnet at the end onto the plurality of faces with the magnets joined to each other. <P>SOLUTION: The fixing device comprises a container 20 in which the magnet 30 is enclosed and which is provided at the end of one object to be fixed 11, wherein the other object to be fixed 10 including the magnet at the end can be fixed to the surface of the container. When the object to be fixed including the magnet at the end is moved closer to a site on the surface of the container, the internal magnet is moved and rotated, and then pulled to the inside face of the container at the site to join an N-pole to an S-pole, whereby the object to be fixed is fixed to the surface of the container with increased friction force between the object to be fixed and the surface of the container due to the attraction of the magnets to each other. When the surface of the container is curve-shaped, the magnet can be freely moved and rotated in the container and so the object to be fixed can be rotated as it remains adhered to the surface of the container in a tangent-vector direction relative to the center of curvature at the site where the object to be fixed is fixed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a fixing device and a hinge mechanism for fixing two or more objects to be fixed.

In the prior art, for example, a hinge device that can freely fix and rotate a fixed object on a spherical surface cannot be made. In addition, in order to be able to fix one fixed object including magnets at the end portions by coupling the magnets on a plurality of surfaces, it is necessary to attach magnets to the surfaces. Is required.

The present invention realizes a hinge device that can freely fix and rotate an object to be fixed on a curved surface with respect to the above two problems, and uses one magnet and includes a magnet at one end on a plurality of surfaces. It is an object to be able to fix an object to be fixed by coupling magnets.

Means to solve the problem

A container enclosing a magnet is provided at the end of one object to be fixed so that the other object to be fixed including the magnet at the end can be fixed to the surface of the container. When a fixed object including a magnet is brought close to a place on the surface of the container, the internal magnet moves and rotates and is attracted to the surface inside the container at the place, and is coupled with the N pole and the S pole. The object to be fixed is fixed to the container surface by an increase in frictional force between the object to be fixed and the surface of the container due to the attractive force between them.

When the container surface has a curved shape, the magnet can freely move and rotate inside the container, so the adhesion to the container surface in the tangent vector direction is maintained with respect to the center of curvature at the place where the object is fixed. The object to be fixed can be rotated as it is.

If the container is a polyhedron with no curvature, the non-fixed object cannot be rotated, but the magnet can move and rotate freely inside the container. An object to be fixed can be strongly fixed in a direction perpendicular to the surface.

The invention's effect

The present invention realizes a hinge device that can freely fix and rotate an object to be fixed on various curved surfaces, which is not found in the prior art.

This invention implement | achieves enabling it to fix one fixed object which contains a magnet in the edge part in multiple surfaces using the coupling | bonding of magnets which is not seen in a prior art.

The embodiment of the invention is as described in “Means for Solving the Problems”. To achieve the invention efficiently, use as strong a magnet as possible, match the shape of the magnet to the shape of the surface of the container, make the container enclosing the magnet as thin as possible, and friction between the container and the object to be fixed. One example is to increase the coefficient as much as possible.

It is the figure which looked from the side which provided the cylindrical container which enclosed the magnet in the edge part of the to-be-fixed object, and fixed the other to-be-fixed object which contains the magnet in the edge part to the container surface. It is the front view which provided the spherical container which divided the inside into two and enclosed the magnet in the edge part of the to-be-fixed object, and fixed two to-be-fixed objects which contain a magnet in the edge part to the container surface. It is the front view which provided the rectangular parallelepiped container which enclosed the magnet in the edge part of the to-be-fixed object, and fixed the other to-be-fixed object which contains a magnet in the edge part to the container surface. It is the front view which fixed to the main body the screen part which provided two cylindrical containers which enclosed the magnet in the main body of the mobile telephone, and provided two magnets in the corresponding position.

Claims (3)

At one end of one object to be fixed, a container having a partitioned space in which one or a plurality of magnets are enclosed is provided, and the other object to be fixed including a magnet or a ferromagnetic material at the end is One or more fixing devices that can be fixed to the surface of the container. When a fixed object including a magnet or a ferromagnetic material at the end is brought close to a place on the surface of the container, the internal magnet moves and rotates and is attracted to the surface inside the container at that position, and is coupled by the N and S poles. The object to be fixed is fixed to the surface of the container by an increase in frictional force between the object and the surface of the container due to the attractive force between the magnets or between the magnet and the ferromagnetic material. The container surface has a curved shape, and the magnet can move and rotate freely inside the container, so that adhesion to the container surface is maintained in the tangential vector direction with respect to the center of curvature at the place where the object is fixed. The object to be fixed can be rotated as it is. 2. The fixing device according to claim 1, wherein the container is a polyhedron having no curvature. Although the non-fixed object cannot be rotated, since the magnet can freely move and rotate inside the container, the object to be fixed can be strongly fixed in a direction perpendicular to any surface constituting the container. 2. The fixing device according to claim 1, wherein the container or the container and the inside thereof are replaced with a ferromagnetic material without enclosing the magnet. It can be rotated in the direction of the tangent vector with respect to the center of curvature at the place where the object to be fixed is fixed to the ferromagnetic surface. Although the fixing force is relatively inferior to that of the first aspect, the processing is easy and the cost is low.
