Herein, the accommodation body is a non-magnetic substance sealing container and the magnet can also be sealed in such a manner that a line of magnetic force of the magnet sealed in the container becomes approximately perpendicular to a joint surface to which the free joint device is joined.

Description

  The present invention relates to a universal joining apparatus that performs joining freely by the magnetic force of a permanent magnet.

  The store partitions, exhibition booths, and shelter partitions in the event of a disaster are not permanently installed and need to be easy to install because they change according to the situation.

  In addition, it is desirable that the degree of freedom of installation, that is, the angle between the partition plates can be set freely (or flexibly).

Patent Document 1 discloses a technical idea in which a partition plate is installed with L-type, T-type, and X-type groove joints. It is a notable idea in that it is easy to assemble and disassemble without using a clasp such as bolts or screws, but the partition plate is limited to 90 degrees or 180 degrees, and when joining at a free angle You must make a grooved joint that fits that angle.

Further, in Patent Document 1, since the partition plate is joined with the crimping force of the upper and lower groove-type joints, when an oblique force is applied to the partition plate, the groove-type joint may come off and the partition plate may fall down. There is.

  On the other hand, Patent Document 2 discloses a technical idea in which a square hole is formed in an end face of a partition plate, and two partition plates are joined by a special wedge-shaped guide and a bolt. If this technology is used, there is no fear that the joint will come off even if a little force is applied, but the partition plate needs to be processed, and joining takes a lot of work such as fitting the guide and tightening the bolts. .

  Moreover, in patent document 2, like patent document 1, joining of a partition plate will be limited to 90 degree | times or 180 degree | times.

JP 2003-49502 A Japanese Patent Laid-Open No. 9-256517

  In view of the background art as described above, it is possible to easily install store partitions, exhibition booths, and shelter partitions at the time of a disaster, and to realize a universal joining device that can freely set the partitioning angle of partition plates. It is a problem.

  In order to solve the above-described problems, a universal joining device according to the present invention includes a container made of a non-magnetic material and a magnet enclosed in the container so as to be movable in the container (claim). Item 1).

  Further, the container is a non-magnetic enclosure, and the magnet is enclosed so that the magnetic lines of force of the magnet enclosed in the container are substantially perpendicular to the joining surface to which the universal joining device joins (claim) Item 2).

Further, the container is a non-magnetic enclosure, and the magnet is sealed so that the magnetic lines of force of the magnet enclosed in the container are substantially parallel to the joining surface to which the universal joining device is joined. A non-magnetic enclosure structure that does not change is defined (claim 3).

  The universal joining apparatus is configured such that the outer shape of the container or the non-magnetic material enclosure is cylindrical and can be freely joined at an arbitrary angle.

  In the universal joining device, the outer shape of the container or the non-magnetic material enclosure is made polygonal, so that the joining force can be made stronger than the cylindrical shape when the joining surface is a plane (claims). 5).

  In the universal joining apparatus, a mounting member is added to the container or the non-magnetic material enclosure (claim 6).

  The universal joining device is configured to be able to be combined with a hollow non-magnetic container in which the outer dimensions of the container or the non-magnetic enclosure are suitable.

In the universal joining device, the container or the non-magnetic enclosure container is configured to have a watertight structure (claim 8).

  Conventionally, the installation of the partition plates is time-consuming, and it has been difficult to arbitrarily set the joint installation angle between the partition plates. However, if the universal joining apparatus according to the present invention is used, the partition plates are joined together by the magnetic force of the magnet, so that the joining can be performed without using any special tool. Furthermore, since the joint installation angle between the partition plates can be arbitrarily set, partition according to the situation can be performed. This function enables an efficient office configuration. Furthermore, the partition board layout can be freely and easily performed in the exhibition hall, and the display effect can be enhanced.

As explained in the background section above, in the conventional joining device, there is a possibility that the joining device may come off or break when an excessive force is applied to the joining portion. Since the joining is performed by the magnetic force of a strong magnet such as a neodymium magnet, even if an unreasonable force is applied to the joining portion, the joining portion is only slightly displaced and the universal joining device according to the present invention is not destroyed.

  In addition, the universal joining device according to the present invention can be used in a wide range of applications, and can be used as a device to replace hinges, or can be set at any angle, and can be rusted by a signboard, guide plate support, or watertight structure. It can also be applied to hinge mechanisms without worry.
