Although all of Patent Documents 1 to 3 describe furniture made by combining a plurality of columnar members and joint members used for product display shelves, etc., all of them are combined with tubular members. The furniture, which is a combination of these, and the product display shelves themselves were not fixed. That is, it was necessary to separately fix the completed furniture or the like by arranging it on the floor surface or the like.

Therefore, it is an object of the present invention to provide a joint member that can not only fix a plurality of columnar members but also fix itself to a structure or the like. It is also an object of the present invention to provide a shelf and an assembly kit.

As a result of diligent studies to achieve the above-mentioned problems, the present inventors have found that the above-mentioned problems can be achieved by the following configurations.

When the parallel polyhedron is a hexahedron, columnar members for vertical columns can be fixed above and below the joint member, and columnar members for shelf board support can be fixed on the front, back, left, and right, so that it can be used as a joint member for forming furniture, shelves, and the like. , Easier to use.

[3] The joint member according to [1] or [2], which has 1 to 3 flanges.

When having one flange, the joint member can be fixed to the wall surface, floor surface, ceiling, etc., and when having two flanges, the joint member can be fixed to the wall surface and floor surface, wall surface and wall surface, and wall surface and ceiling. The joint member can be fixed at the intersection of the floor (corner of the room), etc., and when there are three flanges, the joint member is the intersection of the floor surface and the two wall surfaces, and the ceiling and the two wall surfaces. The joint member can be fixed to (the corner of the room) or the like. Therefore, better stability can be obtained when a shelf or the like is assembled.
It is preferable that the flanges are arranged on adjacent surfaces of the parallelepiped.

[4] The joint member according to any one of [1] to [3], wherein the diameter of the screw insertion hole is 10 to 60% of the nominal diameter of the female screw hole.

If the screw insertion hole is 10% or more of the nominal diameter of the female screw hole, a screw with a nominal diameter that can fix the joint member more firmly can be used, and if it is 60% or less, it is generated by the head of the screw. , The flange part that receives the compressive force for fastening can be secured more sufficiently.

[5] The joint member according to any one of [1] to [4], wherein the columnar member is a shredded bolt.

When the columnar member is a shredded bolt, it can be easily adjusted to the desired length for both the vertical column and the shelf board, so that the furniture to be assembled and / or the design of the shelf, and , The variation of the structure is wider.

[6] An assembled frame including a columnar member having a male screw formed at at least one end thereof and the joint member according to any one of [1] to [5].

Since the assembled frame includes the joint member, it can be freely fixed to a wall surface, a ceiling, or the like, and thus has an excellent feature that it can be installed in various places.

[7] The assembly frame according to [6], wherein the joint member is screwed onto the structure by a screw inserted from the inside of the joint member through the screw insertion hole.

Stability is further enhanced by screwing (fastening) the joint member to the structure. It can also be hung from the ceiling or the like.

[8] The assembly frame according to [6] or [7], wherein the columnar member is a shredded bolt.

When the columnar member is a shredded bolt, the position of the joint member can be set to an arbitrary position of the columnar member, so that the height of the shelf board and the like can be adjusted more freely.

[9] An assembly kit including a columnar member having male screws formed at least at both ends and the joint member according to any one of [1] to [5].

According to the above assembly kit, since the joint member can be fixed to the structure, a more stable frame can be assembled. Further, since the frame can be supported by the joint member fixed to the structure, it can be hung from the ceiling or the like.
If the columnar member is a shredded bolt, the position of the joint member can be set to an arbitrary position of the columnar member, so that a frame having more designs and structures can be assembled.

[10] A joint member for inserting and fixing the tip of a columnar member having a male screw formed on at least one end thereof, which is composed of a substantially parallel polyhedron substrate, and has a male on each surface of the parallel polyhedron. A joint member in which a female screw hole that can be screwed with a screw is formed.
