At this point, the wooden display shelf 10 is complete.

To disassemble the wooden display shelf 10, first, the wooden shelf board 15, the bracket 29, the wooden front panel 41, the wooden top rail 14, and the wooden back panel 13 are disassembled in this order. Next, the shafts 75 of the pair of protrusions 74 provided on the male metal fitting 71 on the wooden back plate 12 side are moved from the narrow portion 85 of the hole 83 provided on the female metal fitting 81 on the wooden column part 11 side to the wide portion. After moving to 84 , the entire protrusion 74 is pulled out from the wide portion 84 . As a result, the engagement between the male side metal fitting 71 and the female side metal fitting 81 is released, and the pair of wooden pole parts 11 and the wooden back plate 12 are disassembled. That is, since the wooden display shelf 10 is disassembled into a plurality of light and small parts, each part can be easily transported.

Therefore, according to this embodiment, the following effects can be obtained.

(1) In the wooden display shelf 10 of the present embodiment, the protrusion 74 of the male metal fitting 71 attached to the wooden back plate 12 is engaged with the hole 83 of the female metal fitting 81 attached to the wooden pole part 11. A pair of wooden pillar parts 11 can be connected via the wooden back plate 12 only by putting them together. Further, the wooden back plate 12 can be removed from the pair of wooden column parts 11 only by removing the protrusion 74 of the male metal fitting 71 from the hole 83 of the female metal fitting 81 . As a result, the two wooden pillar parts 11 can be connected and removed in a short time, and the wooden display shelf 10 can be assembled and disassembled in a short time.

(2) For example, a plate-shaped hook (protrusion) is provided on the male side metal fitting and a slit hole (hole) is provided on the female side metal fitting. Engagement with a female side metal fitting is also considered. However, since the hook is in the form of a thin plate, there is a problem that it is easily deformed when an external force acts on the engaging portion between the hook and the slit hole. In addition, since the hook is inserted into the narrow slit, the frictional force between the hook and the slit is large, making it difficult to remove the hook from the slit. Therefore, for example, when the wooden display shelf 10 needs to be disassembled in order to relocate the wooden display shelf 10 between stores or to move the wooden display shelf 10 due to a layout change in the store, the wooden display shelf 10 can be disassembled. It is necessary to ask a craftsman to disassemble the display shelf 10 . In addition, forcible disassembly may lead to deformation or breakage of each part.

On the other hand, in the present embodiment, the projection 74 of the male side metal fitting 71 is shaped like a rivet consisting of a shaft portion 75 and a head portion 76, that is, is three-dimensional rather than planar. The strength is higher than that in the case of, for example, a plate shape. Therefore, even if an external force acts on the engagement portion between the protrusion 74 and the hole portion 83, that is, the joint portion between the wooden pillar part 11 and the wooden back plate 12, the joint portion is less likely to be damaged, so that the wooden pillar part can be secured. 11 and the wooden back plate 12 can be increased in joint strength. In addition, in the present embodiment, when the protrusion 74 and the hole 83 are engaged with each other, only a part of the outer peripheral surface of the shaft portion 75 contacts the inner peripheral surface of the hole 83, so that friction between the two is caused. power is small. Therefore, when removing the wooden back plate 12 from the wooden pillar part 11, the projecting part 74 can be easily removed from the hole part 83, so that the wooden display shelf 10 can be disassembled in a short time without asking a craftsman. be able to.

(3) In the present embodiment, the wood screw 91 inserted through the column portion 21 is screwed into the projection screw hole 89 provided in the projection 88 of the female side metal fitting 81 . The screwing direction is different from the engaging direction of the protrusion 74 of the male metal fitting 71 with the hole 83 of the female metal fitting 81 (see FIGS. 5 and 6). As a result, even if an external force acts on the female side metal fitting 81 from a plurality of directions, the female side metal fitting 81 is less likely to be damaged, and the attachment strength of the female side metal fitting 81 to the column portion 21 is increased.

In addition, you may change this embodiment as follows.
