SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for assembling modular furniture elements using hollow metal pipes with open ends.

[0004]

The object of the present invention is to fix a threaded socket having a rib on the outside and open at both ends in a metal pipe, and a flat head bolt is engaged with the socket to flatten the flat surface. Insert the threaded part of the head bolt into the threaded part of the cylindrical connecting part that has screw holes in the center and the periphery, and pass the threaded part of the flat head bolt through the receiving part that has a surface that matches the surface of this connecting part to form the connecting part. A method of assembling a modular furniture element using a hollow metal pipe with open ends, characterized in that another metal pipe is fixed via a flat head bolt.

With the method of the present invention, it is possible to assemble a scaffold that can be disassembled using a straight pipe in such a way that the use of a connecting joint is invisible. In the method of the present invention, a hollow pipe whose both ends are open is used, and a threaded socket is fixed inside the hollow pipe, and the internal threaded socket is inserted into the thread portion of the outer collar. It engages two threaded bolts and has a flat cylindrical ring inserted on the outer collar, which is threaded at the end of the right angle shank of this cylindrical ring to allow it to rotate freely around the metal shank. An outer ring is attached to the cylindrical ring via an edge having a slightly larger diameter, and a screw hole is formed in the center of the outer ring.

[0006]

In the assembled state, the unit assembled by the method of the present invention has neither a protrusion nor an outward bulge and the spherical fixed ball cannot be seen. Therefore, there is no protrusion on the surface of the pipe assembly. The rotation of the cylindrical ring can be prevented by externally tightening the head of the flat head bolt.

It is also possible to fix the flat head bolt to the assembly device thus produced via a hollow screw and to which the second longitudinal tubular element is fixed. Rotation of the cylindrical intermediate member is prevented by a threaded bolt inserted in the screw hole. The outer thread of this threaded bolt allows the second assembly element to be fixed at an angle of 45 °, 60 ° or 90 ° and allows the vertical mounting of at least one cylindrical tubular element via a hollow flat head bolt. .

In the method of the present invention, the scaffold of the pipe is square,
They can be stacked in a rectangular or polygonal shape, and on top of this scaffolding superposed or snap-in building elements can be assembled.

The great advantages of the assembly system of the present invention are:
The point is that the surface can be perfectly smooth and completely homogeneous without the use of assembly joints. This system can assemble the pipe-shaped elements in any direction, and can also rotatably rotate the panel.
Office furniture can be made from modular elements using the method of the present invention. Also, a door can be attached to the pipe element, or a bracket or a glass partition can be fixed to form a display cabinet. Side panels can also be inserted between the pipe elements. This panel is completely fixed and will not come out of the groove unless pressure is applied or it is pulled out from the inside.

The present invention will be described in detail below with reference to the accompanying drawings. The removable assembly device shown is
It includes a cylindrical assembly part that is inserted between the assembly pipes, the parts being formed with holes pointing towards the end of each pipe. In a preferred embodiment of the present invention, the sleeve or insert member of the present invention is fitted longitudinally or laterally to the work surface into a slightly projecting hollow metal edge to provide an outer edge and insert part. It is designed to be firmly meshed along the length corresponding to the space between the outer periphery and. Therefore, the sleeve or the insert member can be fixed to the work surface without traveling, and the pipe structure can be assembled vertically or horizontally.

The pipe structure of the present invention serves as a base for assembling the assembling elements, and the assembling is completed by inserting the rigid panel in the groove between the pipes, and storing and storing elements such as files for storing elements, cupboards, bookshelves. And display shelves and the like. The partition can be a rigid, opaque material, such as wood or metal, and can be transparent or translucent, such as glass, polycarbonate polymers. It is also possible to combine a transparent element and an opaque element to form an element that is transparent on one side and opaque on the other side.
