【Example】

 [First Embodiment]

FIG. 7 shows a shelf support structure in which a wooden shelf B is assembled in two stages on a box-shaped wooden frame A. The frame A is constructed by assembling a left and right side wall A1, a bottom plate A2, a top plate A3, and a back plate A4 into a box shape, and each of the shelf plates B is disposed on both left and right side walls A1 facing each other with the shelf plate B in between. It is placed and supported on the metal shelf board supporting parts 1 attached two by two. Figure 3
As shown in FIG. 6, the shelf support component 1 has a side wall A.
The shaft member 3 that is fitted into the lateral hole 2 having a constant inner diameter formed in 1 and the cylindrical support member 4 that mounts and supports the shelf board B are integrally provided in a vertically displaced position. ing.

At the base of the support member 4, a support member axis X
A flange 5 having an abutment surface 5a in a direction orthogonal to the is integrally formed, and the shaft member 3 has a base outer diameter D with a lateral hole 2 so that the shaft member 3 can be vertically swung in a state of being fitted in the lateral hole 2.
The upper end surface 6a is formed in a truncated cone shape having an inner diameter of about 10 mm and an outer diameter that gradually decreases toward the tip side, and extends along the longitudinal direction of the shaft member 3.
Is formed in a shape parallel to the support member axis X.

Three wedge-shaped first claw members 7 are integrally formed at intervals on the upper surface of the shaft member 3 toward the tip end side, and the shaft member 3 together with these first claw members 7 is provided with a lateral hole 2. The vertical height H between the lower end surface 6b of the shaft member 3 and the tip of the first claw member 7 is slightly shorter than the inner diameter of the lateral hole 2 so that the shaft member 3 can be inserted therein.

Then, as shown in FIG. 1, the support member 4 is positioned on the lower side, and the shaft member 3 is fitted into the lateral hole 2 together with the first pawl member 7, and then the support member 4 is directly or manually hammered. When the shaft member 3 is swung downwards as indicated by an arrow, the shaft member 3 swings upwards with the corner portion of the lateral hole 2 and the side wall A1 as a fulcrum, and as shown in FIG. 5a abuts the side wall A1 wall surface, and the first claw member 7
Bites into the wood portion of the inner surface of the sideways hole, and the support member 4 is fixed in a cantilevered manner substantially horizontally, and immovably fixed toward the side wall A1 facing the shelf plate B. Therefore, it is difficult for the shaft member 3 to fall out of the sideways hole 2 during the assembling of the shelf board B, and the weight on the shelf board B side keeps the first claw member 7 around the inner circumference of the sideways hole even when the shelf board B is in use. Since it acts in a direction to bite into the surface, there is little risk that the shelf board support component 1 will fall off and the shelf board B will come off.

A groove 8 having an arcuate cross section into which the support member 4 is fitted is formed on the lower surface of the shelf board B, and the shelf board B is mounted and supported by fitting the support member 4 into the groove 8. The movement of B in the front-rear direction is restricted, and the support member 4 and the lower surface of the shelf board B are meshed with each other when the shelf board B is placed on the support member 4 to support the shelf board B. A meshing portion 9 that restricts the movement toward the 4th free end side is provided.

The engagement portion 9 is formed by integrally forming a wedge-shaped second claw member 11 projecting above the shelf mounting surface 10 at the tip of the support member 4, as shown in FIG. By pushing down or knocking down the shelf board B to place it on the shelf board placing surface 10, the second claw member 11 bites into the wood part of the lower surface of the shelf board B in the groove 8 and engages with the shelf board B. Relative movement with the member 4 in the direction of the support member axis X is restricted.
Therefore, by placing the shelf board B on the left and right support members 4, the relative separation movement between the shelf board B and the left and right side walls A1 can be performed.
It is regulated via the, and the assembling shape of the shelf board B and the left and right side walls A1 is not easily deformed.

The retaining member 14 is formed, and the support member 4
Two annular second claw members 11 having an isosceles-shaped cross section are formed on the outer peripheral surface of the. Then, the shaft member 3 is knocked into the sideways hole 2 so that the support member 4 is fixed in a cantilevered state substantially horizontally, and is immovably fixed toward the side wall A1 facing the shelf plate B, and the shelf plate B is fixed. Is pushed down or struck to be placed on the shelf board mounting surface 10, the second claw member 11 bites into and meshes with the wood part of the lower surface of the shelf board B over substantially the entire circumference of the groove 8, and the shelf board B concerned. A meshing portion 9 that restricts the movement of the support member 4 to the free end side is formed. Other configurations are similar to those of the first embodiment.

[Third Embodiment] FIGS. 9A and 9B show an embodiment in which one annular second claw member 11 is formed on the tip side of the support member 4, and the second claw is shown. The cross section of the member 11 is formed in a triangular shape having a surface 15 orthogonal to the axis X of the support member 4. Other configurations are the same as those in the second embodiment.
