Through holes 21 are formed respectively on the end side and the center side of 11 so as to match the through holes 12.

The connecting spring 30 has a substantially U-shaped leaf spring main body 31 whose tip (opening) side is widened. Only one side 31 a of the leaf spring main body 31 is provided with a step 31 b on the tip side. Two engaging projections 32, which are fitted to the through holes 12 and 21, are formed on the tip end side of the step 31b of the one side 31a while being separated from the sides and widening the gap between the other sides 31c on the tip opening side. It is projected to each. The engaging projection 32 has a circular cross section.

In the framed board 40, a frame wall 42 having a relatively narrow width is protruded from the back surface of a square or rectangular plate-like body 41. The frame wall 42 is similar to the plate-like body 41 and is slightly smaller than this. The flange portion 41a of the plate-like body 41 is formed on the outer peripheral side of the frame wall 42. In addition, in the vicinity of the corners of the frame wall 42, two through holes 43 respectively corresponding to the through holes 12 formed in the insertion support pipe 11 and the connecting pipe 20 and the through holes 21 are provided in total near each of them. Six are formed. Although not shown in FIGS. 1 and 2, notches are formed at the corners of the flange portion 41a of the plate-like body 41 to avoid interference with the main body 13 of the connecting member 10.

To assemble the above-mentioned members from the disassembled state shown in FIG. 1 to the frame assembly shown in FIG. 2, the following is performed. First, the connecting spring 30 is pushed into each insertion support tube 11 of the connecting member 10 from the tip (opening) side of the leaf spring main body 31, so that the leaf spring main body 31 of the connecting spring 30 has a width on the tip side. Two through-holes formed in the insertion support tube 11 by elastically deforming it so as to narrow it and supporting it on the inner surface of the insertion support tube 11 by its restoring force, and forming two engagement protrusions 32 provided in the leaf spring main body 30 in the insertion support tube 11. 12 respectively.

Next, the end portion of the connecting pipe 20 is fitted into the insertion support pipe 11, and the two through holes 21 formed at the end portions of the insertion support pipe 11 protrude from the through hole 12 of the insertion support pipe 11. The fitting protrusions 32 are engaged with each other to connect the insertion supporting pipe 11 and the connecting pipe 20, and by using four of these, a square frame or a rectangular frame is formed.

After that, the frame wall 42 of the framed board 40 is fitted into the formed square frame or rectangular frame, and the connecting pipes 20 are connected to the two through holes 43 formed at each corner of the frame wall 42. Each of the two engaging protrusions 32 protruding from the through hole 21 is engaged with each other so that the back surface of the flange portion 41a of the plate-like body 41 provided on the framed board 40 is supported on the front surface of the connecting pipe 20. Form a framework assembly.

The square frame or the rectangular frame composed of the connecting member 10 and the connecting pipe 20 shares a part of the connecting pipe 20, and a plurality of them are connected half-dimensionally and three-dimensionally. The framed board 40 is attached to the required frame to construct a shelf or the like on which articles are placed (see FIG. 5).

[0011]

[Problems to be solved by the device]

 In the frame assembly having the above-described configuration, the through holes 43 provided in the frame wall 42 of the framed board 40 are engaged with the engaging protrusions 32 provided in the leaf spring main body 31 of the connecting spring 30 to form the framed board. Since the flange portion 41a of 40 is only supported on the surface of the connecting pipe 20, the framed board 40 is firmly fixed to the square frame or the rectangular frame formed by the connecting member 10 and the connecting pipe 20. However, the framed board 40 may fall out of the square frame or the rectangular frame. In particular, the connecting member 10 and the connecting pipe 20 are used, a part of the connecting pipe 20 is shared, and a plurality of square frames and rectangular frames are continuously provided. When the 40 is attached, the framed board 40 is more likely to come off.

That is, since only one connecting spring 30 is inserted into the insertion supporting pipe 11 of the multidirectional connecting member 10, the coupling spring 30 located at one end of the shared connecting pipe 20 is engaged. The mating protrusion 32 is engaged with the through hole 21 of the connecting pipe 20 and the through hole 43 of the frame wall 42 of the framed board 40 located on one side of the connecting pipe 20 so that the other end of the connecting pipe 20 is secured. The engaging protrusions 32 of the connecting spring 30 located therein are engaged with the through holes 21 of the connecting pipe 20 and the through holes 43 of the frame wall 42 of the framed board located on the other side of the connecting pipe 20. Therefore, the number of engagement projections 32 engaging with the frame walls 42 of the framed board 40 located on both sides of the shared connecting pipe 20 is reduced, and the framed board 40 is more easily disengaged from a square frame or the like ( (See FIG. 5).

The present invention can easily solve the above-mentioned problems by improving the engaging protrusions of the connecting spring, and can reliably prevent the framed board from falling off the square frame or the rectangular frame. It is intended to provide an assembly.
