Abstract

PROBLEM TO BE SOLVED: To obtain a rigid structure by the simple processing of a member, in a shelf device in which shelf plates which can be arranged by being vertically inverted are supported by pipe-made columnar supports.SOLUTION: An annular groove 11 is formed at an external peripheral face of a columnar support 2, and a bush 12 having an inward salient 16 is stacked on the columnar support 2 from the outside in a two-dividing system. An external periphery of the bush 12 is narrowed upwardly and tapered, and a cylinder body 5 welded to a shelf plate 1 is downwardly fit in a come-off impossible manner. The cylinder body 5 has a straight shape, and the cylinder body 5 and the bush 10 are held in a relative movement disabled state by making an inward annular protrusion 17 formed at a vertical intermediate part abut on the bush 10. By this constitution, a shelf device is excellent in rigidity. Since the cylinder body 5 is formed of a pipe as a raw material, dimension accuracy becomes high, and a vertical height relationship of the bush 10 can be constantly held.

Description

本願発明は、棚板に設けた上下開口の筒体がブッシュを介して支柱で支持された構造の棚装置に関するものである。本願発明の棚装置には、定置式のものとキャスター(コロ、車輪)を備えた移動自在なワゴンとの両方を含んでいる。   The present invention relates to a shelf apparatus having a structure in which a cylindrical body having an upper and lower opening provided on a shelf board is supported by a support via a bush. The shelf device of the present invention includes both a stationary type and a movable wagon equipped with casters (rollers and wheels).

ワゴン方等の棚装置として、支柱に丸パイプを使用したものがある。この棚装置の棚板は一般に平面視四角形になっており、4つのコーナー部に上下開口の円形の金属製筒体を固着し、筒体がブッシュを介して支柱で支持されている。   There is a shelf device such as a wagon that uses a round pipe as a support. The shelf plate of this shelf apparatus is generally rectangular in plan view, and a circular metal cylinder having upper and lower openings is fixed to four corners, and the cylinder is supported by a support via a bush.

ブッシュは2つ割り方式になっており、2つのパーツを重ねた状態では、内面は支柱にきっちり重なるストレートで、外周面は上窄まりのテーパになっている。そして、支柱の外周面に環状溝が所定間隔で形成されている一方、ブッシュの内面には内向き突条が形成されており、内向き突条を環状溝に嵌めることでブッシュを支柱で落下不能に保持すると共に、ブッシュのテーパ面で棚板の筒体を落下不能に支持している。なお、ブッシュの下端に外向きのフランジを設けて、フランジで筒体を落下不能に支持する場合もある。   The bush is split into two, and when two parts are stacked, the inner surface is a straight that exactly overlaps the column, and the outer peripheral surface is a tapered taper. Annular grooves are formed on the outer peripheral surface of the support column at a predetermined interval, while inward protrusions are formed on the inner surface of the bush, and the bushes are dropped by the support column by fitting the inward protrusion into the annular groove. The cylinder of the shelf is supported by the tapered surface of the bush so that it cannot fall. In some cases, an outward flange is provided at the lower end of the bush, and the cylinder is supported by the flange so that it cannot fall.

棚板に固定した筒体の内面は、ストレートになっている場合と上窄まりのテーパ面になっている場合とがある。すなわち、棚板の配置姿勢に上下の方向性がない場合は、筒体の内面は上窄まりのテーパ面になっており、このたため、筒体は上下全長にわたってブッシュにきっちり嵌まり、これにより、棚板はブッシュを介して支柱で落下不能に支持される(例えば特許文献1)。   The inner surface of the cylindrical body fixed to the shelf board may be straight or may be a tapered surface with a constriction. That is, when there is no vertical orientation in the arrangement position of the shelf, the inner surface of the cylindrical body is a tapered surface that is narrowed, and therefore, the cylindrical body fits tightly on the bush over the entire vertical length. The shelf board is supported by a support through a bush so as not to fall (for example, Patent Document 1).

他方、棚板が例えばトレー状で上向き開口した姿勢と下向き開口した姿勢とに変更自在なように、配置姿勢について上下の方向性がある場合は、筒体の内面はストレートになっていて、筒体の下部がブッシュの下部で嵌合支持されるようになっている(例えば特許文献2)。   On the other hand, if there is a vertical orientation in the arrangement posture so that the shelf plate can be changed into a tray-open posture that is open upward and a posture that opens downward, for example, the inner surface of the cylinder is straight, The lower part of the body is fitted and supported by the lower part of the bush (for example, Patent Document 2).

特許文献2のように筒体の内面がストレートであると、筒体の下端部しかブッシュにきっちり嵌合しないため、安定性に欠ける問題がある。そこで特許文献3には、筒体をストレートに形成することに代えて、上下中間部を境にして上窄まりテーパと下窄まりテーパとに形成することで、棚板の配置姿勢に関係なく筒体の半分をブッシュにきっちり嵌めるようにした構成が開示されている。   When the inner surface of the cylindrical body is straight as in Patent Document 2, only the lower end portion of the cylindrical body is fitted into the bush exactly, so that there is a problem of lack of stability. Therefore, in Patent Document 3, instead of forming the cylindrical body straight, the upper and lower intermediate portions are used as the boundary to form an upper taper and a lower taper, regardless of the arrangement position of the shelf board. A configuration is disclosed in which half of the cylinder is fitted into the bush exactly.

さて、スチール棚のような金属製棚の場合、筒体も金属製としてこれを棚本体に溶接することになるが、特許文献1のように内面が上下逆向きのテーパ構造であると、筒体5は切削加工せねばならないためコストが嵩むのみならず、加工誤差があるとブッシュとの嵌まり合いが不正確になる虞がある。   In the case of a metal shelf such as a steel shelf, the cylinder is also made of metal and is welded to the shelf body. Since the body 5 has to be machined, not only does the cost increase, but if there is a machining error, the fitting with the bush may become inaccurate.

本願発明は、このように現状を改善すべく成されたものである。   The present invention has been made to improve the current situation in this way.

本願発明の棚装置は、棚板とこれを支持するパイプ状又は棒状の支柱とを備えており、前記棚板にはブッシュを介して前記支柱に嵌まる筒体が固定されており、前記ブッシュの内面に、前記支柱の外面に設けた外向き係合部に嵌まる内向き係合部が形成されている。   The shelf device of the present invention includes a shelf plate and a pipe-like or rod-like support column that supports the shelf plate, and a cylindrical body that fits into the support column is fixed to the shelf plate via a bush. An inward engagement portion that fits in an outward engagement portion provided on the outer surface of the support column is formed on the inner surface of the support column.

一方、前記ブッシュの外周面は上窄まりのテーパ状に形成されており、前記ブッシュの下部に前記筒体の下部がきっちり嵌合することにより、前記筒体がブッシュを介して支柱で落下不能に支持されている。そして、前記筒体の内周面とストレート形状であり、その内面のうち上下中途高さ位置に内向きの環状突起を形成している。   On the other hand, the outer peripheral surface of the bush is formed in a tapered shape, and when the lower portion of the cylindrical body is fitted to the lower portion of the bush, the cylindrical body cannot be dropped by the support via the bush. It is supported by. And it is straight shape with the internal peripheral surface of the said cylinder, and the inward annular protrusion is formed in the up-and-down middle height position among the inner surfaces.

本願発明において、筒体の環状突起は概ね外周方向に延びておればよく、完全なループになって連続している必要はない。従って、複数に分断されているものや、一部が途切れているものも本願発明の環状突起に含まれる。また、本願発明の棚装置は、例えば引出しのような附属装置を備えていてもよいし、複数段の棚板を備えている場合は、少なくとも1段の棚板が本願発明の構成になっていたらよい。   In the present invention, the annular protrusions of the cylindrical body only need to extend substantially in the outer circumferential direction, and need not be continuous in a complete loop. Therefore, what is divided | segmented into plurality and what is partly interrupted are also contained in the cyclic | annular protrusion of this invention. Further, the shelf device of the present invention may be provided with an attached device such as a drawer, and when it is provided with a plurality of shelf plates, at least one shelf plate is a configuration of the present invention. I hope.

本願発明では、筒体の内面はストレートでありながら、環状突起がブッシュの外周面に当接又は近接することで、筒体とブッシュとを相対動しない状態に保持することができ、これにより、棚板の姿勢安定性を向上させることができる。その結果、棚装置の堅牢性を向上させることができる。そして、環状突起は外周側から押し出す膨出加工で簡単に形成できるため、加工コストを低く押さえることができる。また、筒体は円形等の鋼管等の金属パイプを使用できるため、内径は高い寸法精度に維持できる。   In the present invention, while the inner surface of the cylindrical body is straight, the annular projection can be held in contact with or close to the outer peripheral surface of the bush, so that the cylindrical body and the bush can be held in a relatively non-moving state. It is possible to improve the posture stability of the shelf board. As a result, the robustness of the shelf device can be improved. And since an annular protrusion can be easily formed by the bulging process extruded from an outer peripheral side, processing cost can be held down low. Further, since the cylindrical body can use a metal pipe such as a circular steel pipe, the inner diameter can be maintained with high dimensional accuracy.

従って、本願発明によると、配置姿勢に上下の方向性がない棚板を備えた棚装置を、コストアップと加工精度の低下とを押えつつ、横からの外力に強い堅牢な構造で提供することができる。   Therefore, according to the present invention, to provide a shelf apparatus having a shelf plate with no vertical orientation in the arrangement posture, with a robust structure that is strong against external force from the side, while suppressing an increase in cost and a decrease in processing accuracy. Can do.

(1).第1実施形態
次に、本願発明の実施形態を図面に基づいて説明する。まず、図1〜図4に示す第1実施形態(主たる実施形態)を説明する。本実施形態はワゴンタイプの棚装置に適用しており、棚装置は、平面視略四角形(長方形)の3段の棚板1と、各棚板1をそのコーナー部において支持する4本の支柱2と、各支柱の下端に取り付けたキャスター3とを備えている。なお、キャスター3を備えていていない場合は、各支柱2の下端にはアジャスターボルトや樹脂製接地体を設けることが多い。
(1). First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment (main embodiment) shown in FIGS. 1 to 4 will be described. The present embodiment is applied to a wagon type shelf device, and the shelf device is a three-stage shelf board 1 having a substantially rectangular (rectangular) shape in plan view, and four support columns that support each shelf board 1 at its corners. 2 and a caster 3 attached to the lower end of each column. In addition, when the caster 3 is not provided, an adjuster bolt or a resin grounding body is often provided at the lower end of each column 2.

各棚板1は、上向きに開口したトレー状の本体4と、本体4の四隅部に溶接された上下開口の筒体5とで構成されている。本体4はスチール板製(ステンレス板製でもよい)であり、図3に明示するように、水平姿勢の基板(底板又は天板と呼んでもよい)6と、その外周縁(4辺)に連接された鉛直姿勢の外周壁7と、外周壁7の先端から基板6の側に曲げられた内周壁8とを有している。外周壁7と内周壁8との間は空間になっており、従って、外周壁7と内周壁8とからなる周壁部は中空状になっている。   Each shelf board 1 is composed of a tray-like main body 4 that opens upward and a cylindrical body 5 having upper and lower openings welded to the four corners of the main body 4. The main body 4 is made of a steel plate (may be made of a stainless steel plate) and, as clearly shown in FIG. 3, is connected to a horizontally oriented substrate (which may be called a bottom plate or a top plate) 6 and its outer peripheral edge (four sides). The outer peripheral wall 7 having a vertical posture and the inner peripheral wall 8 bent from the tip of the outer peripheral wall 7 toward the substrate 6 are provided. The space between the outer peripheral wall 7 and the inner peripheral wall 8 is a space. Therefore, the peripheral wall portion composed of the outer peripheral wall 7 and the inner peripheral wall 8 is hollow.

本実施形態では、外周壁7の水平方向の延長線と筒体5の外周面とが接するように設定しており、従って、隣り合った2つの外周壁7の延長線で囲われたコーナー部の内側に筒体5が配置されている。もとより、筒体5が隣り合った2つの外周壁7の延長線で囲われたコーナー部の外側に部分的にはみ出たり、逆に、隣り合った2つの外周壁7を当接させて、その内側に筒体5を配置してもよい。   In the present embodiment, the horizontal extension line of the outer peripheral wall 7 and the outer peripheral surface of the cylindrical body 5 are set in contact with each other. Therefore, the corner portion surrounded by the extension lines of the two adjacent outer peripheral walls 7 is set. A cylindrical body 5 is arranged on the inside. Of course, the cylindrical body 5 partially protrudes outside the corner portion surrounded by the extension line of the two adjacent outer peripheral walls 7, or conversely, the two adjacent outer peripheral walls 7 are brought into contact with each other. You may arrange | position the cylinder 5 inside.

外周壁7と内周壁8との連接部9は半円状の形態になっているが、略水平姿勢であってもよい。内周壁8の上下幅寸法は外周壁7のそれよりも小さい寸法になっており、先端は、外周壁7に当接又は近接する傾斜姿勢の端片8aになっている。端片8aの存在により、安全性が図られている。なお、端片8aの先端は、基板6と外周壁7とが繋がった内角部に当接又は近接させてもよい。   The connecting portion 9 between the outer peripheral wall 7 and the inner peripheral wall 8 has a semicircular shape, but may have a substantially horizontal posture. The vertical width dimension of the inner peripheral wall 8 is smaller than that of the outer peripheral wall 7, and the tip is an end piece 8 a in an inclined posture that abuts or approaches the outer peripheral wall 7. Safety is achieved by the presence of the end piece 8a. Note that the tip of the end piece 8a may be in contact with or close to the inner corner where the substrate 6 and the outer peripheral wall 7 are connected.

筒体5は丸鋼管(ステンレス管でもよい)を素材にして製造されており、本体4と略同じ高さ寸法になっている。筒体5は、本体4を構成する外周壁7及び内周壁8並びに基板6に溶接されている(基板6には溶接せずに、外周壁6と内周壁7とのみに溶接してもよい。)。筒体5を本体4に直接溶接することに代えて、本体4にコーナー金具を溶接し、このコーナー金具に筒体5を溶接することも可能である。最上段の棚板1の筒体5には、樹脂製のキャップ10を装着している。   The cylindrical body 5 is manufactured using a round steel pipe (or a stainless steel pipe) as a raw material, and has substantially the same height as the main body 4. The cylindrical body 5 is welded to the outer peripheral wall 7 and the inner peripheral wall 8 and the substrate 6 constituting the main body 4 (it may be welded only to the outer peripheral wall 6 and the inner peripheral wall 7 without being welded to the substrate 6). .) Instead of welding the cylinder 5 directly to the main body 4, it is also possible to weld a corner fitting to the main body 4 and weld the cylinder 5 to this corner fitting. A resin cap 10 is attached to the cylinder 5 of the uppermost shelf 1.

支柱2は鋼管製(ステンレス管製でもよい)であり、その外周には、外向き係合部の一例として、外向きに開口した環状溝11を適宜間隔(例えば筒体5の上下高さの半分のピッチ)で多数形成している。なお、環状溝11は、材料たるパイプに外側からロールを押し当てる膨出加工で形成されている。   The support column 2 is made of a steel pipe (may be made of a stainless steel pipe), and an annular groove 11 that opens outward is provided as an example of an outward engagement portion on the outer periphery thereof (for example, the vertical height of the cylindrical body 5). Many are formed at a half pitch). In addition, the annular groove 11 is formed by the bulging process which presses a roll from the outside to the pipe which is material.

支柱2と筒体5との間には、樹脂製のブッシュ12が介在している。ブッシュ12は、2つ割状に形成された2つのパーツ13から成っており、2つのパーツ13を重ねてブッシュ10と成すと、内面は支柱2に密着するストレート形状で、外周面は上窄まりテーパ形状になる。   A resin bush 12 is interposed between the column 2 and the cylinder 5. The bush 12 is composed of two parts 13 formed in a split shape. When the two parts 13 are overlapped to form the bush 10, the inner surface is a straight shape that is in close contact with the support column 2, and the outer peripheral surface is constricted. A tapered shape.

両パーツ13の上下中途高さ位置には、外向きの突起14と内向き切欠き15とが軸心を挟んで対称状に形成されている。従って、2つのパーツ13は同一形状になっており、2つのパーツ13を重ねると、一方のパーツ13の突起14と他方のパーツ13の切欠き15とが嵌まり合い、これにより、両パーツ13は上下ずれ不能に保持される。突起14と切欠き15は位置決め手段の一例であって、それぞれ側面視四角形に形成されているが、側面視三角形や半円状、或いはカマボコ形などの形状でもよい。位置決め手段は、上下複数の位置に設けることも可能である。   An outward projection 14 and an inward notch 15 are formed symmetrically on both sides of the upper and lower parts of the parts 13 with the axis centered therebetween. Accordingly, the two parts 13 have the same shape, and when the two parts 13 are overlapped, the protrusion 14 of one part 13 and the notch 15 of the other part 13 fit together, whereby both parts 13 Is held so that it cannot be displaced vertically. The protrusions 14 and the notches 15 are examples of positioning means, and are each formed in a square shape in a side view, but may have a shape such as a triangle shape in a side view, a semicircular shape, or a kamaboko shape. The positioning means can be provided at a plurality of positions above and below.

ブッシュ12の内面には、内向き係合部の一例として、支柱2の環状溝11に嵌まり込む内向き突条(環状突起)16を形成している。内向き凸条16はそれぞれパーツ13の内周の全長にわたって途切れずに延びているが、断続するように形成してもよい。   On the inner surface of the bush 12, as an example of an inward engagement portion, an inward protrusion (annular protrusion) 16 that fits in the annular groove 11 of the support column 2 is formed. The inwardly protruding ridges 16 extend without interruption throughout the entire inner circumference of the part 13, but may be formed to be intermittent.

ブッシュ12の外周面は上窄まりのテーパであるが、上端部の外径は筒体5の内径よりは小さく、下端部の外径は筒体5の内径よりは少し大きい。このため、筒体5はブッシュ12によって落下不能に保持される。図4のように、筒体5を下方に押し込み切った状態で、当該筒体5の下端とブッシュ12の下端とは略同じ高さになるように設定しているが、ブッシュ12の下端が筒体5の下方に若干はみ出ていてもよい。また、ブッシュ12(パーツ13)の下端に外向きのフランジを形成することも可能である。   The outer peripheral surface of the bush 12 is a tapered taper, but the outer diameter of the upper end is smaller than the inner diameter of the cylinder 5, and the outer diameter of the lower end is slightly larger than the inner diameter of the cylinder 5. For this reason, the cylinder 5 is held by the bush 12 so as not to drop. As shown in FIG. 4, the lower end of the cylindrical body 5 and the lower end of the bush 12 are set to have substantially the same height when the cylindrical body 5 is pushed down downward. It may protrude slightly below the cylinder 5. It is also possible to form an outward flange at the lower end of the bush 12 (part 13).

ブッシュ12の外周面は上窄まりのテーパ形状なので、ブッシュ12の外周面と筒体5の内周面との間には隙間が空いている。そこで、図4に明示するように、筒体5の上下中途高さ位置に、ブッシュ12の外周面に当接又は近接する内向きの環状突起17を形成している。環状突起17は、筒体5に外側からロールを押し当てて変形させる膨出加工(押し曲げ加工)によって、簡単に形成できる。なお、環状突起17を膨出加工するに際しては、筒体5の内部に受け棒を配置してもよい。   Since the outer peripheral surface of the bush 12 has a tapered shape that is narrowed, there is a gap between the outer peripheral surface of the bush 12 and the inner peripheral surface of the cylindrical body 5. Therefore, as clearly shown in FIG. 4, an inward annular protrusion 17 that is in contact with or close to the outer peripheral surface of the bush 12 is formed at a height position in the middle of the cylinder 5. The annular protrusion 17 can be easily formed by a bulging process (push bending process) in which a roll is pressed against the cylindrical body 5 from the outside and deformed. When the annular protrusion 17 is bulged, a receiving rod may be disposed inside the cylinder 5.

棚装置には平面視コ字形の把手19を設けている。把手19の両端には棚板1に設けたのと同じ構造の筒体20を溶接で固着しており、筒体5は棚板1を支持するのと同じブッシュ12で支柱2に取り付けられている。   The shelf device is provided with a U-shaped handle 19 in a plan view. A cylindrical body 20 having the same structure as that provided on the shelf 1 is fixed to both ends of the handle 19 by welding, and the cylindrical body 5 is attached to the support column 2 by the same bushing 12 that supports the shelf 1. Yes.

以上の構成において、環状突起17がブッシュ10に当接又は密接しているため、ブッシュ12と筒体5とはきっちりと嵌合した状態が保持されており、これにより、棚装置は横からの力に強い堅牢な状態に保持されている。また、環状突起17は筒体5の上下中間部に設けているため、棚板1を下向き開口の姿勢で配置しても、環状突起17はブッシュ12にきっちり当接又は近接する。そして、筒体5はパイプを素材にして製造されているため、その内径は高い寸法精度になっている。従って、ブッシュ12と筒体5との高さ関係を一定に保持して、見栄えを良くすることができる。   In the above configuration, since the annular protrusion 17 is in contact with or in close contact with the bush 10, the bush 12 and the cylindrical body 5 are kept in a tightly fitted state. It is held in a strong and strong state. Further, since the annular protrusion 17 is provided at the upper and lower intermediate portions of the cylindrical body 5, the annular protrusion 17 is brought into close contact with or close to the bush 12 even when the shelf board 1 is arranged in the downward opening posture. And since the cylinder 5 is manufactured using the pipe as a raw material, the inner diameter has high dimensional accuracy. Therefore, the height relationship between the bush 12 and the cylinder 5 can be kept constant, and the appearance can be improved.

(2).他の実施形態
図5に示す第2実施形態では、棚板1の本体4の別例を示している。筒体5やブッシュ12は第1実施形態と同じ構造である。この第2実施形態では、本体4を構成する内周壁8のうち外周壁7に繋がった基端部8bと自由端の側の先端部8cとを外周壁7の内面に密着又は近接させ、内周壁8のうち内向き突出部(中空部)を内向き凸の台形状に形成している。
(2). Other Embodiments In the second embodiment shown in FIG. 5, another example of the main body 4 of the shelf board 1 is shown. The cylinder 5 and the bush 12 have the same structure as in the first embodiment. In the second embodiment, the base end portion 8b connected to the outer peripheral wall 7 and the distal end portion 8c on the free end side of the inner peripheral wall 8 constituting the main body 4 are brought into close contact with or close to the inner surface of the outer peripheral wall 7. An inward protruding portion (hollow portion) of the peripheral wall 8 is formed in an inwardly convex trapezoidal shape.

従って、内周壁8が外周壁7に部分的に重なっており、この互いに重なり合った部分の端が筒体5に溶接されている。このため、剛性が高くなっている。分図(B)に一点鎖線で示すように、内周壁8の内向き突出部に縦長のスリット8dを適宜間隔で飛び飛びで多数形成し、スリット8dに仕切り板(図示せず)を嵌め込むことも可能である。スリット8dは4枚の内周壁8の全てに形成してもよいし、対向した2枚の内周壁8のみに形成してもよい。   Therefore, the inner peripheral wall 8 partially overlaps the outer peripheral wall 7, and the end of the overlapping portion is welded to the cylindrical body 5. For this reason, the rigidity is high. As indicated by the alternate long and short dash line in the partial diagram (B), a large number of vertically long slits 8d are formed on the inwardly protruding portion of the inner peripheral wall 8 at appropriate intervals, and a partition plate (not shown) is fitted into the slit 8d. Is also possible. The slits 8d may be formed on all four inner peripheral walls 8 or only on the two inner peripheral walls 8 facing each other.

図5に示す第3実施形態も棚板1の本体4の別例である。この実施形態でも、筒体5やブッシュ12は第1実施形態と同じ構造である。この実施形態では、外周壁7と内周壁8との間にはある程度の空間が空いていると共に、内周壁7の先端には、外周壁6の内面に重なる折り返し片8fを形成している。また、内周壁7には、外周壁6に当接又は近接する上下長手のリブ21を横方向に適宜間隔で多数形成している。   The third embodiment shown in FIG. 5 is another example of the main body 4 of the shelf board 1. Also in this embodiment, the cylinder 5 and the bush 12 have the same structure as that of the first embodiment. In this embodiment, a certain amount of space is provided between the outer peripheral wall 7 and the inner peripheral wall 8, and a folded piece 8 f that overlaps the inner surface of the outer peripheral wall 6 is formed at the tip of the inner peripheral wall 7. The inner peripheral wall 7 is formed with a large number of vertically long ribs 21 that are in contact with or close to the outer peripheral wall 6 at appropriate intervals in the lateral direction.

この実施形態では、折り返し片8eとリブ18の群とにより、棚板1の剛性が格段に高くなっている。縦長のリブ18に代えて、横長のリブやX形のリブを形成することも可能である。縦長のリブ18を外周壁7と内周壁8との連接部9まで延長すると、剛性はより一層高くなる。   In this embodiment, the rigidity of the shelf board 1 is remarkably increased by the folded piece 8e and the group of ribs 18. Instead of the vertically long ribs 18, horizontally long ribs or X-shaped ribs may be formed. When the vertically long rib 18 is extended to the connecting portion 9 between the outer peripheral wall 7 and the inner peripheral wall 8, the rigidity is further increased.

図7(A)に示す害4実施形態では、棚板1のうち平行に延びる2つの外周壁7の中間部に筒体5を固着している。他方、図6(B)に示す第5実施形態では、棚板1の平行に延びる2つの外周壁7の2カ所ずつに筒体5を溶接している。   In the harm 4 embodiment shown in FIG. 7A, the cylindrical body 5 is fixed to the middle part of the two outer peripheral walls 7 extending in parallel among the shelf boards 1. On the other hand, in the fifth embodiment shown in FIG. 6B, the cylindrical body 5 is welded to each of two locations of the two outer peripheral walls 7 extending in parallel with the shelf board 1.

(3).その他
本願発明は、上記の実施形態の他にも様々に具体化できる。例えば棚板1はトレー状である必要はなく、網状や籠状とすることも可能である。トレー状の形態とする場合は、周壁は二重構造でなく、一重や三重構造でもよい。多層構造にする場合、第1実施形態のような内折りでなく外折り構造にしてもよい。棚板に仕切りを設けることも可能である。筒体は樹脂製とすることも可能であり、この場合も、射出成形によって高い寸法精度に製造できる。
(3). Others The present invention can be embodied in various ways other than the above embodiment. For example, the shelf board 1 does not need to be in a tray shape, and may be in a net shape or a bowl shape. In the case of a tray-like form, the peripheral wall may not be a double structure but a single or triple structure. In the case of a multi-layer structure, an outer folding structure may be used instead of the inner folding as in the first embodiment. It is also possible to provide a partition on the shelf board. The cylinder can be made of resin, and in this case, it can be manufactured with high dimensional accuracy by injection molding.

支柱とブッシュとの係合手段としては、支柱に外向きの突条を形成して、ブッシュに内向きの環状溝を形成したり、支柱に係合穴を形成してブッシュに係合ピンを形成したりすることも可能である。棚板の平面視形状は四角形である必要はなく、円形や楕円形など、用途に応じて任意に設定できる。   As the means for engaging the support column with the bush, an outward protrusion is formed on the support column, an inward annular groove is formed on the bush, or an engagement hole is formed on the support column and an engagement pin is formed on the bush. It can also be formed. The plan view shape of the shelf board does not need to be a quadrangle, and can be arbitrarily set according to the application, such as a circle or an ellipse.

本願発明は、実際に棚装置に適用できる。従って、産業上利用できる。   The present invention can actually be applied to a shelf device. Therefore, it can be used industrially.
