従来、棚板の側壁に取り付ける受具と、前記棚板に取り付けて前記受具と係合する係合具とから構成された「棚板取付装置」が知られている（特許文献１の２頁左欄１５〜４０行及び第１〜８図参照）。
上記した従来の受具と係合具とは、タッピングねじをねじ込むことで固定していた（特許文献１の２頁右欄２５〜２８行及び第２図参照）。 2. Description of the Related Art Conventionally, there is known a “shelf mounting device” that includes a receiver that is attached to a side wall of a shelf and an engaging tool that is attached to the shelf and engages with the receiver (see Patent Document 1 2). (Refer to page left column 15-40 lines and FIGS. 1-8).
The conventional receiving tool and the engaging tool described above were fixed by screwing a tapping screw (see Patent Document 1, page 2, right column, lines 25 to 28 and FIG. 2).

また、従来、棚板の下面に設けられた凹状の嵌装穴に嵌装されるジョイント本体と、前記ジョイント本体のスリット溝に摺動可能に配設されるジョイントキャップとを備えた「ジョイント装置」が知られている（特許文献２の段落番号「００１０」、図１〜３及び図６参照）。
上記した従来のジョイント本体には、断面視略エ字状溝（凹溝）が設けられ、当該断面視略エ字状溝（凹溝）に、棚板が取り付けられる側壁に突設された棚受けピンを嵌め込み、その後、ジョイントキャップを装着することで、断面視略エ字状溝（凹溝）を閉じていた（特許文献２の段落番号「００１０」及び図１〜３参照）。 Further, conventionally, a “joint device including a joint body that is fitted in a concave fitting hole provided on the lower surface of the shelf board and a joint cap that is slidably disposed in a slit groove of the joint body.

上壁140には、図７〜９、図１１及び図１２に示すように、上面から突出する複数の突起部141を設けている。突起部141は、斜面を後方に向けた略直角三角形形に形成される。
突起部141は、第二部材50を棚板30の凹部31に嵌め込んだ状態では、図１及び図２１に示すように、上側閉塞面33に食い込むことが可能なものである。また、斜面を後方に向けた直角三角形形に突起部141を形成したことから、凹部31の開口側面34の方向の第二部材50の移動を防止できる。 As shown in FIGS. 7 to 9, 11 and 12, the upper wall 140 is provided with a plurality of protrusions 141 protruding from the upper surface. The projecting portion 141 is formed in a substantially right triangle shape with the inclined surface facing rearward.
The protrusion 141 can bite into the upper closing surface 33 as shown in FIGS. 1 and 21 in a state where the second member 50 is fitted in the recess 31 of the shelf board 30. Further, since the protrusion 141 is formed in a right triangle shape with the inclined surface facing rearward, the movement of the second member 50 in the direction of the opening side surface 34 of the recess 31 can be prevented.

なお、突起部141は、略直角三角形形に形成したが、当該形状に限定されない。
（棚板30の取付方法）
上記構成を備えた棚板固定具10を使用した棚板30の取付方法について、図１、図１３〜２１を用いて以下に説明する。
まず、図１、図２、図６及び図１９に示すように、第一部材40の軸保持部70に軸部60を装着し、当該軸保持部70から突出した軸部60の軸本体61を、側壁20に設けられる穴21に挿入する。 In addition, although the projection part 141 was formed in the substantially right-angled triangle shape, it is not limited to the said shape.
(Installation method of shelf board 30)
The attachment method of the shelf board 30 using the shelf fixture 10 provided with the said structure is demonstrated below using FIG. 1, FIG.
First, as shown in FIGS. 1, 2, 6 and 19, the shaft portion 60 is mounted on the shaft holding portion 70 of the first member 40, and the shaft main body 61 of the shaft portion 60 protruding from the shaft holding portion 70. Is inserted into the hole 21 provided in the side wall 20.

軸本体61を挿入すると、その外周から突出する凸部62が、穴21の内周に食い込むことで、軸本体61の抜けを防止する。このため、第一部材40は、軸部60を介して、側壁20の穴21に仮に保持される。
一方、図１及び図１９に示すように、第二部材50を、棚板30の下面側に設けられた凹部31に合わせて嵌め込む。 When the shaft main body 61 is inserted, the projecting portion 62 protruding from the outer periphery bites into the inner periphery of the hole 21 to prevent the shaft main body 61 from coming off. For this reason, the first member 40 is temporarily held in the hole 21 of the side wall 20 via the shaft portion 60.
On the other hand, as shown in FIGS. 1 and 19, the second member 50 is fitted into the recess 31 provided on the lower surface side of the shelf plate 30.

第二部材50は、凹部31の開口底面32に合わせて、下側から上側に嵌め込む。このとき、第二部材50の上壁140が、図２１に示すように、凹部31の上側閉塞面33に突き当たるまで深く挿入する。
第二部材50を深く挿入すると、その上壁140から突出する突起部141が、凹部31の上側閉塞面33に食い込むことで、凹部31内での第二部材50の水平方向の移動を阻止できる。 The second member 50 is fitted from the lower side to the upper side in accordance with the opening bottom surface 32 of the recess 31. At this time, the second member 50 is inserted deeply until the upper wall 140 abuts against the upper closing surface 33 of the recess 31 as shown in FIG.
When the second member 50 is inserted deeply, the protrusion 141 protruding from the upper wall 140 bites into the upper closing surface 33 of the recess 31 so that the horizontal movement of the second member 50 in the recess 31 can be prevented. .

また、第二部材50を嵌め込んだ際に、その係合部121及び抜止部122が、凹部31内の左右の側方閉塞面36に押されて撓み、当該側方閉塞面36に弾性的に当接ないしは食い込む。
このため、第二部材50は、凹部31内に仮に保持され、当該凹部31の開口底面32や開口側面34から第二部材50が抜け落ちるのを防止できる。
最後に、図１９〜２１に示すように、側壁20に仮に保持された第一部材40に、棚板30の凹部31を上方からかぶせるように載置する。 Further, when the second member 50 is fitted, the engaging portion 121 and the retaining portion 122 are pushed and bent by the left and right side closing surfaces 36 in the recess 31, and are elastically applied to the side closing surface 36. Abut or bite into.
For this reason, the second member 50 is temporarily held in the recess 31, and the second member 50 can be prevented from falling off from the opening bottom surface 32 and the opening side surface 34 of the recess 31.
Finally, as shown in FIGS. 19 to 21, the first member 40 temporarily held on the side wall 20 is placed so as to cover the concave portion 31 of the shelf board 30 from above.

棚板30を載置すると、凹部31内に仮に保持された第二部材50の開口下面100（図１１及び図１２参照）から、第一部材40の軸保持部70が嵌り込む。
軸保持部70が嵌り込むと、その固定部72に押されて、第二部材50の爪状の保持部131が撓むことで、軸保持部70が第二部材50の内部で相対的に上昇し、保持部131が凹状の固定部72に節度感を伴って「パチン」と嵌り込むことで、第二部材50の内部に軸保持部70が保持され、開口下面100から軸保持部70が抜け落ちるのを防止できる。 When the shelf plate 30 is placed, the shaft holding portion 70 of the first member 40 is fitted from the opening lower surface 100 (see FIGS. 11 and 12) of the second member 50 temporarily held in the recess 31.
When the shaft holding part 70 is fitted, it is pushed by the fixing part 72 and the claw-like holding part 131 of the second member 50 is bent, so that the shaft holding part 70 is relatively moved inside the second member 50. The shaft holding portion 70 is held inside the second member 50 by the rise and the holding portion 131 is fitted into the concave fixing portion 72 with a sense of moderation, and the shaft holding portion 70 is held from the lower surface 100 of the opening. Can be prevented from falling off.

このとき、第一部材40のフランジ部80が、図２０及び図２１に示すように、棚板30の凹部31の開口底面32の周縁に当接し、当該開口底面32を塞ぐ。
同時に、第二部材50の内部に第一部材40の軸保持部70を嵌め込んだ際に、図１６に示すように、その左右の外側面により、左右の係合部121の対向する内側面が押されて、外向きに大きく突出する。このとき、係合部121の外側面から突出する第１突部123と第２突部124との一方若しくは両方が、凹部31内の側方閉塞面36に強く当接ないしは食い込む。 At this time, as shown in FIGS. 20 and 21, the flange portion 80 of the first member 40 abuts on the peripheral edge of the opening bottom surface 32 of the concave portion 31 of the shelf board 30 and closes the opening bottom surface 32.
At the same time, when the shaft holding portion 70 of the first member 40 is fitted into the second member 50, the inner surfaces of the left and right engaging portions 121 are opposed to each other by the left and right outer surfaces as shown in FIG. Is pushed and protrudes greatly outward. At this time, one or both of the first protrusion 123 and the second protrusion 124 protruding from the outer surface of the engaging portion 121 strongly abuts or bites into the side blocking surface 36 in the recess 31.

このため、棚板30の凹部31内に、図２１に示すように、第二部材50が固定される。
したがって、棚板30は、棚板固定具10を介して、側壁20の穴21の高さ位置に固定され、地震等に振動により棚板30が浮き上がって側壁20から外れるのを防止できる。
（穴21や凹部31の加工上のバラ付きやピッチズレの許容）
つぎに、穴21や凹部31の加工上のバラ付きやピッチズレに対する棚板固定具10の作用について、以下に説明する。 For this reason, the second member 50 is fixed in the recess 31 of the shelf board 30 as shown in FIG.
Therefore, the shelf board 30 is fixed to the height position of the hole 21 of the side wall 20 via the shelf board fixture 10, and it is possible to prevent the shelf board 30 from being lifted by the earthquake or the like and coming off the side wall 20.
(Acceptable variation and pitch deviation in processing of hole 21 and recess 31)
Next, the action of the shelf fixture 10 on the variation or pitch shift in processing the holes 21 and the recesses 31 will be described below.

まず、高さ方向のズレに対しては、第一部材40の弾性部90が、図１７及び図１８に示すように、当該高さ方向に伸縮することで、当該高さ方向のズレを吸収する。
すなわち、第一部材40の軸保持部70は、図２０及び図２１に示すように、第二部材50を介して棚板30の凹部31内に固定され、第一部材40のフランジ部80は、棚板30の凹部31の開口底面32の周縁に当接していることから、軸保持部70とフランジ部80との距離が変化した場合には、弾性部90が高さ方向に伸縮する。 First, with respect to the displacement in the height direction, the elastic portion 90 of the first member 40 absorbs the displacement in the height direction by expanding and contracting in the height direction as shown in FIGS. To do.
That is, as shown in FIGS. 20 and 21, the shaft holding portion 70 of the first member 40 is fixed in the recess 31 of the shelf board 30 via the second member 50, and the flange portion 80 of the first member 40 is Since the abutment is in contact with the peripheral edge of the opening bottom surface 32 of the recess 31 of the shelf plate 30, when the distance between the shaft holding portion 70 and the flange portion 80 changes, the elastic portion 90 expands and contracts in the height direction.

このため、高さ方向のズレに対しては、弾性部90が高さ方向に伸縮することで、当該高さ方向のズレを吸収することができる。
また、高さ方向や水平方向の複合的なズレに対しては、弾性部90の左右一対の脚片92が左右非対称に伸縮したり、或いはよじれたり、ねじれるように屈曲することで、当該ズレを吸収することが可能である。 For this reason, with respect to the deviation in the height direction, the elastic part 90 expands and contracts in the height direction, so that the deviation in the height direction can be absorbed.
Further, with respect to a composite displacement in the height direction and the horizontal direction, the pair of left and right leg pieces 92 of the elastic portion 90 are bent so as to expand or contract asymmetrically, bend or twist. Can be absorbed.

したがって、加工上のバラ付きやピッチズレを弾性部90により吸収することができるので、当該加工上のバラ付きやピッチズレがある場合にも、棚板固定具10を使用した棚板30の取り付けが可能であるばかりでなく、棚板30を平らに或いは水平に取り付けることができる。 Therefore, since the variation and pitch deviation in processing can be absorbed by the elastic portion 90, the shelf plate 30 can be attached using the shelf fixing tool 10 even when there is variation or pitch deviation in the processing. In addition, the shelf board 30 can be mounted flatly or horizontally.
