図１は折畳みトレー棚を使用状態で示す斜視図である。側板３は上棚４、下棚５、フック７から構成される。上棚４と下棚５はそれぞれ上下に配置され上棚４と下棚５の間にフック７が挟み込まれる。上棚４の上側にもフック７を設置する。上棚４と下棚５は間隔が違う鍔１１を水平に設けてある。図５に示すように上棚４の上端を鍔１１と逆方向水平（外側）に折り曲げ、水平部に柱軸６が貫通する貫通孔を設ける。同様に下棚５の下端を鍔１１と逆方向水平（外側）に折り曲げ、水平部に柱軸６が貫通する貫通孔を設ける。フック７は前後に細長い板を長手方向に垂直に折り曲げた構造である。図５に示すように、フック７の水平面の端部を鍔１２とし、フック７の端部の柱軸６が貫通する水平面に貫通孔を設ける。側板３の上棚４、下棚５の鍔１１とフック７の鍔１２が内側を向くように左右対称に設置し、その側板３の前後に柱軸６を設置する。図５に示すように、左右柱軸６を繋ぐ接続棒８の両端面には軸受け蓋１０を設けその軸受け蓋１０には垂直方向に柱軸６が通る貫通孔を設けている。柱軸６は軸受け蓋１０に設けた貫通孔に回転可能に勘合する。左右にある側板３に対し上下前後にある接続棒８を直角に配置する事で、多段に鍔１１がある折畳みトレー棚の使用状態になる。トレー１を外した状態で左右にある側板３の前後方向に偶力が掛かると柱軸６を軸に接続棒８が回転し、図２、図３に示すように左右側板３が接近しあい平行四辺形に変形し、折畳まれようとする。それを規制する為に、左右側板３の上側と上側前後に設置された接続棒８の上面にできた四角形の空間に、四角形の天板２を嵌め込む事で、左右の側板３に対して各接続棒８が直角を保持でき、折畳みを防止する機能を有する。柱軸６の下側にはキャスター９を備える。 FIG. 1 is a perspective view showing a folding tray shelf in use. The side plate 3 includes an upper shelf 4, a lower shelf 5, and a hook 7. The upper shelf 4 and the lower shelf 5 are arranged vertically, and a hook 7 is sandwiched between the upper shelf 4 and the lower shelf 5. A hook 7 is also installed above the upper shelf 4. The upper shelf 4 and the lower shelf 5 are horizontally provided with ridges 11 having different intervals. As shown in FIG. 5, the upper end of the upper shelf 4 is bent horizontally (outside) in the opposite direction to the flange 11, and a through hole through which the column shaft 6 passes is provided in the horizontal portion. Similarly, the lower end of the lower shelf 5 is bent horizontally (outside) in the opposite direction to the flange 11, and a through hole through which the column shaft 6 passes is provided in the horizontal portion. The hook 7 has a structure in which a long and narrow plate is bent vertically in the longitudinal direction. As shown in FIG. 5, the end of the horizontal plane of the hook 7 is a flange 12, and a through hole is provided in the horizontal plane through which the column shaft 6 at the end of the hook 7 passes. The side plate 3 is installed symmetrically so that the upper shelf 4 of the side plate 3, the lower shelf 5 of the side shelf 5 and the hook 12 of the hook 7 face inward, and the column shafts 6 are installed before and after the side plate 3. As shown in FIG. 5, bearing lids 10 are provided on both end surfaces of the connecting rod 8 connecting the left and right column shafts 6, and through holes through which the column shafts 6 pass are provided in the bearing lids 10 in the vertical direction. The column shaft 6 is rotatably fitted in a through hole provided in the bearing lid 10. By arranging the connecting rods 8 at the top and bottom and at right angles to the side plates 3 on the left and right, the folding tray shelf with the ridges 11 in multiple stages is used. When a couple is applied in the front-rear direction of the left and right side plates 3 with the tray 1 removed, the connecting rod 8 rotates around the column shaft 6, and the left and right side plates 3 approach and collide as shown in FIGS. It transforms into a quadrilateral and tries to be folded. In order to regulate it, the rectangular top plate 2 is fitted into the rectangular space formed on the upper surface of the connecting rod 8 installed on the upper side and the upper front and rear sides of the left and right side plates 3, so that Each connecting rod 8 can hold a right angle and has a function of preventing folding. A caster 9 is provided below the column shaft 6.

図２は折畳みトレー棚を保管状態（折畳んだ状態）で示す斜視図である。トレー1及び天板２を外す事により、左右にある向かい合った側板３及び、上下前後にある接続棒８は柱軸６を軸にそれぞれ水平回転可能となり、左右にある側板３が接近し平行四辺形に変形でき、折畳むことが可能となる。また外した天板２を紛失しないように、側板３の上側と中間部にあるフック７の垂直折り曲げ部に、天板２を垂直に取り付けることができる。 FIG. 2 is a perspective view showing the folding tray shelf in a storage state (folded state). By removing the tray 1 and the top plate 2, the side plates 3 facing each other on the left and right and the connecting rods 8 on the top and bottom can be rotated horizontally around the column axis 6, respectively. It can be transformed into a shape and can be folded. Moreover, the top plate 2 can be vertically attached to the vertical bent portions of the hooks 7 on the upper side and the middle portion of the side plate 3 so that the removed top plate 2 is not lost.

図３は折畳みトレーの上面図で使用状態と折畳んだ状態を重ねた図で、使用状態では、左右側板３に接続棒８が直角に接続されている状態であるが、左側の側板３を固定し右側の側板３に後ろ方向に力を加えることにより、柱軸６を軸に前後にある接続棒８が左回転し、同時に右側にある側板３は左側にある側板３に接近する。左右に向かい合った側板３の上棚４、下棚５、フック７の鍔１１同士が接触するまで平行四辺形に変形でき、左右にある鍔１１同士が接触した状態が最小占有面積となる保管状態（折畳んだ状態）である。当然使用状態にするには、逆方向の力を加えればよい。 FIG. 3 is a top view of the folding tray in which the use state and the folded state are overlapped. In the use state, the connecting rod 8 is connected to the left and right side plates 3 at a right angle. By fixing and applying a backward force to the right side plate 3, the connecting rod 8 at the front and rear of the column shaft 6 rotates leftward, and at the same time, the side plate 3 on the right side approaches the side plate 3 on the left side. A storage state in which the upper shelf 4, the lower shelf 5, and the hooks 7 of the hooks 7 facing the left and right can be transformed into a parallelogram until the hooks 11 contact each other, and the state where the left and right hooks 11 are in contact is the minimum occupied area ( (Folded state). Needless to say, a force in the reverse direction may be applied in order to put it in use.

図４は折畳みトレーの正面上側の部分断面図で、図５は図４のＡ部分の詳細図である。軸柱６が、接続棒８の両端面にある軸受け蓋１０を貫通して接続棒８に軸接続されている。よって軸受け蓋１０を摩擦抵抗の低い材質に変更する事で、可動部の抵抗が減る為、折畳み労力の低減が出来る。 FIG. 4 is a partial sectional view of the upper side of the folding tray, and FIG. 5 is a detailed view of a portion A in FIG. The shaft column 6 passes through the bearing lids 10 on both end faces of the connecting rod 8 and is axially connected to the connecting rod 8. Therefore, by changing the bearing lid 10 to a material having a low frictional resistance, the resistance of the movable part is reduced, so that the folding labor can be reduced.
