本発明は、前記［１］に記載のように、実質上中空状のものとなされた支柱の中空部内に雌ねじ片をスライド自在に装入したものとして、この雌ねじ片に各棚板の隅部を止めねじで連結固定するものとしているので、各棚板の高さ位置を、載置収納しようとする物品に応じて任意の高さ位置に可変設定しうるのはもとより、従来の同様の目的のための構成では、前記特許文献２〜４に見られるように、支柱に多数個の取付孔が長さ方向に所定間隔おきに列設されており、これが外観上いかにも機械部品的な外観印象を与えるものとなって、必ずしも外観体裁上好ましいものではなかったのに対し、本発明においては、前記のように支柱内に内装された雌ねじ片に対して、各棚板を連接固定したものとなされているので、支柱の外観がスッキリしたものとなり、ひいてはスチール棚でありながら家具調の外観を表出する体裁の良好なものとなしうる。 As described in [1] above, the present invention assumes that a female screw piece is slidably inserted into a hollow portion of a column that is substantially hollow, and the corner portion of each shelf plate is inserted into this female screw piece. Are connected and fixed with setscrews, so that the height position of each shelf can be variably set to an arbitrary height position according to the article to be placed and stored, as well as the conventional purpose. In the configuration for, as shown in Patent Documents 2 to 4, a large number of mounting holes are arranged in the length direction at predetermined intervals, and this is an appearance that looks like a mechanical part. However, in the present invention, each shelf plate is connected and fixed to the female screw pieces installed in the support column as described above. As it is made, the appearance of the support is refreshing It shall have, can without a favorable style to expose the exterior Furniture yet turn steel shelves.
また、前記［２］に記載のように、雌ねじ片は、支柱内において係止手段によって任意の高さ位置に仮止め状態に係止固定されるものとなっているから、初期の組立作業時においてはもとより、棚板の高さ変え作業時においても、各支柱における雌ねじ片の高さ位置を揃えて仮保持せしめたのち、これに棚板の隅部を止めねじで順次連結していくことで、容易に棚板を正しく水平状態に付けることができる。かつ雌ねじ片の高さ位置を変える操作も、該雌ねじ片を開口部側からばねに抗して指先で支柱の奥側方向へ押し込むことで係止手段による係合を解除して、支柱の長さ方向に自由にスライド移動させることができる。そして所定の位置に至ったときに指先による押込み力を除けば、ばね部材の弾力で雌ねじ片は開口部側への近接位置に前進移動して、係止手段との適合位置でこれに係合させることができ、ひいては所定の高さ位置に係止め状態に係合保持させることができる。従って、垂直状態に立てた支柱内で、雌ねじ片が不慮、不本意に落下、下降、あるいは位置ずれ移動することがなく、棚板の取付作業、高さ位置変更作業をいずれも簡便に行うことができる。 In addition, as described in [2] above, the female screw piece is locked and fixed in a temporarily fixed state at an arbitrary height position by a locking means in the support column. In addition to the above, even when changing the height of the shelf board, the height positions of the female screw pieces on each column are aligned and temporarily held, and then the corners of the shelf board are sequentially connected with set screws. Thus, the shelf board can be easily placed in the correct horizontal state. In addition, the operation of changing the height position of the female thread piece also releases the engagement by the locking means by pushing the female thread piece from the opening side against the spring against the spring with the fingertip toward the back side of the pillar. It can slide freely in the vertical direction. Then, if the pushing force by the fingertip is removed when the predetermined position is reached, the female thread piece moves forward to a position close to the opening side by the elastic force of the spring member, and engages with this at the fitting position with the locking means. As a result, it can be engaged and held in a locked state at a predetermined height position. Therefore, the female thread pieces do not inadvertently drop, descend, or move out of position in the vertical column, and both the shelf mounting operation and the height position changing operation can be easily performed. Can do.
また、前記［３］に記載の構成によるときは、支柱を金属板からのプレス成形品として比較的安価に製作しうると共に、雌ねじ片と支柱との係合構造部分がほとんど外観されないものとなる。即ち、雌ねじ係止用切欠部が外部露出しないので、愈々外観体裁の良好なものとなしうる。 Further, according to the configuration described in [3] above, the strut can be manufactured as a press-molded product from a metal plate at a relatively low cost, and the engagement structure portion between the female screw piece and the strut is hardly visible. . That is, since the female screw locking notch is not exposed to the outside, the appearance can often be improved.
更に、前記［４］に記載のように、各棚板側においても、その隅部にコーナー止着片を当接配置して、該コーナー止着片と雌ねじ片とを締結することで棚板を挾着固定状態に取付けるものとした場合には、止めねじの必要使用本数を各隅部に１本づつの最小限のものとして、棚組立工数の大幅な削減を可能とし、組立作業の簡易性を向上しうると共に、止めねじの外観露出を最小のものとし、かつ各棚板の内隅部および支柱との取合部の外観をスッキリしたものにして、更に一層、外観体裁の良好なものとなしうる。 Further, as described in [4] above, on each shelf plate side, a corner fastening piece is disposed in contact with the corner portion, and the corner fastening piece and the female screw piece are fastened to each other. When mounting the unit in a fixed state, the required number of set screws is minimized to one for each corner, enabling a significant reduction in shelf assembly man-hours and simplifying assembly work. The appearance of the set screw is minimized and the appearance of the inner corners of each shelf and the joints with the columns are refreshed to further improve the appearance. It can be done.
更にまた、前記［５］に記載のように、前記［１］〜［４］に記載の組立棚の各支柱の下端にキャスターを取付けたワゴンに構成する場合には、前記のような諸効果を保有する、物品搬送にも便利な棚型ワゴンを提供しうる。 Furthermore, as described in [5] above, when the wagon has casters attached to the lower ends of the columns of the assembly shelf described in [1] to [4], the various effects as described above. It is possible to provide a shelf-type wagon that is convenient for conveying goods.
図１は、本発明の金属製組立棚（Ａ）を、その各支柱の下端にキャスター（６）を取付けると共に、上部一側面部に手押し用ハンドル（７）を取付けて、物品の載置保管用、および搬送移動用のワゴン（Ｂ）の形式に構成した態様で示すものである。 FIG. 1 shows a metal assembly shelf (A) according to the present invention, in which a caster (6) is attached to the lower end of each column, and a handle (7) for pushing is attached to an upper side surface portion to place and store articles. It is shown in an embodiment configured in the form of a wagon (B) for use and transporting movement.
金属製組立棚（Ａ）の部分は、その主要構成部品として、３枚以上複数枚の金属製棚板（１）と、その四隅部分を支持する４本の金属製支柱（２）とを具備する。 The metal assembly shelf (A) includes three or more metal shelf boards (1) and four metal columns (2) that support the four corners as main components. To do.
棚板（１）は、鉄板、アルミ板等の金属板をプレス成形して、矩形状等の直角四辺形の浅い箱状に形成されたものである。従って、各棚板（１）は、矩形状の平坦な底板部（１１）と、その周囲四辺から立ち上った周側壁（１２）とを有する。周側壁（１２）は、上端縁が内方に折り返されると共に、棚板（１）の四隅部に欠落部（１３）を有するものとなされ（図２参照）、該欠落部（１３）を通じて後述の止めねじ（３）を貫通させうるものとなされている。もちろん周側壁（１２）を隅部に連続させて欠落部（１３）を有しないものとすることも任意である。その場合、止めねじ挿通用の透孔を形成することで上記欠落部（１３）に代替させ得る。また、棚板（１）は、棚やワゴンの用途との関係で、上下を逆にした下向き浅箱状の姿勢で用いられることもある。この場合も本発明の実施形態の１つである。 The shelf board (1) is formed by press-molding a metal plate such as an iron plate or an aluminum plate into a shallow box shape of a rectangular quadrilateral quadrilateral. Accordingly, each shelf plate (1) has a rectangular flat bottom plate portion (11) and a peripheral side wall (12) that rises from its four sides. The peripheral side wall (12) is configured such that the upper end edge is folded inward and has missing portions (13) at the four corners of the shelf board (1) (see FIG. 2), and will be described later through the missing portion (13). The set screw (3) can be penetrated. Of course, it is also optional that the peripheral side wall (12) is made continuous with the corner and does not have the missing portion (13). In that case, the missing portion (13) can be substituted by forming a through hole for inserting a set screw. Moreover, the shelf board (1) may be used in the downward shallow box-like attitude | position which turned upside down in relation to the use of a shelf or a wagon. This case is also one of the embodiments of the present invention.
支柱（２）は、これも金属板からプレス成形されたものであり、外周壁の一部に長さ方向に連続するスリット状の開口部（２１）を有する実質上中空状のものに形成されている。更に具体的には、支柱（２）は、図２及び図３に示すように、断面Ｌ字形の主体部（２０）と、その両側縁から内方に直角に順次折り曲げられた第１折曲縁（２２ａ）、第２折曲縁（２２ｂ）、および第３折曲縁（２２ｃ）からなる内巻き部（２２）を有し、左右の両内巻き部（２２）（２２）間に前記のスリット状開口部（２１）が形成されたものとなされている。 The column (2) is also formed by press-molding from a metal plate, and is formed in a substantially hollow shape having a slit-like opening (21) continuous in the length direction on a part of the outer peripheral wall. ing. More specifically, as shown in FIGS. 2 and 3, the support column (2) includes a main portion (20) having an L-shaped cross section and a first bent portion that is sequentially bent inward from both side edges at right angles. It has an inner winding part (22) consisting of an edge (22a), a second bent edge (22b), and a third bent edge (22c), and the inner winding part (22) between the left and right inner winding parts (22) (22) The slit-shaped opening (21) is formed.
各支柱（２）の中空部（２３）内には、棚板（１）の数に対応する数の雌ねじ片（４）が上下方向スライド自在に装入されている。該雌ねじ片（４）は、硬質合成樹脂製または金属製のものであり、図２に示されるように全体として横断面略く字状ないしＬ字状で、屈折部の中央位置に貫通状に雌ねじ孔（４ａ）が設けられている。 A number of female screw pieces (4) corresponding to the number of shelf plates (1) are inserted into the hollow portion (23) of each support column (2) so as to be slidable in the vertical direction. The female screw piece (4) is made of hard synthetic resin or metal, and as shown in FIG. 2, as a whole, has a substantially cross-sectional or L-shaped cross section, and penetrates in the center of the refracting portion. A female screw hole (4a) is provided.
この雌ねじ片（４）は、支柱（２）に対して、その中空部（２３）内に、十分な余裕をもってルーズな状態で、かつ開口部（２１）からの脱出を阻止される状態で挿入されており、上下方向へ摺動自在であると共に、図３の（Ｂ）に示されるような支柱（２）の開口部（２１）側に近接した近接位置と、同図（Ａ）に示されるような該開口部（２１）から離れる奥方向への離間位置との間で、横方向に変位移動可能なものとなされている。 The female thread piece (4) is inserted into the hollow portion (23) in the hollow portion (23) with a sufficient margin and in a state in which escape from the opening portion (21) is prevented. It is slidable in the vertical direction and is close to the opening (21) side of the column (2) as shown in FIG. 3B, and shown in FIG. It is possible to move in the lateral direction between the rearwardly spaced position away from the opening (21).
そして、雌ねじ片（４）の背面側、即ち支柱（２）のＬ字状主体部（２０）に面する左右の両側翼部の背面の平面部に、それぞれ断面ハット形の板ばねからなるばね部材（４３）が接着、ピン止め、溶着等の手段で止着されている。このばね部材（４３）の作用で、雌ねじ片（４）は、常時は図３の（Ｂ）に示すような支柱（２）の開口部（２１）への近接位置方向に弾力的に付勢されたものとなされている。従ってまた、雌ねじ片（４）は、支柱（２）の開口部（２１）から指先で奥方向に押し込むことにより、ばね部材（４３）の弾性に抗して前記離間位置、即ち図３の（Ａ）に示すような支柱（２）内の奥寄り位置に移動変位させ得るものとなされている。 And the spring which consists of a leaf | plate spring of a cross-sectional hat shape in the plane part of the back side of the female screw piece (4), ie, the back surface of the both right and left wing parts facing the L-shaped main part (20) of a support | pillar (2), respectively.

Due to the action of the spring member (43), the female thread piece (4) is normally elastically biased in the direction of the position close to the opening (21) of the support (2) as shown in FIG. It has been made. Accordingly, the female thread piece (4) is pushed inward from the opening (21) of the support post (2) with the fingertip, thereby resisting the elasticity of the spring member (43). It can be moved and displaced to a position closer to the back in the column (2) as shown in A).
一方、雌ねじ片（４）は、その両側翼部の前面側に、肉ぬすみ状の凹陥部（４１）（４１）が形成されている。その結果、この凹陥部（４１）の上下に、１対の係止部（４２）（４２）が形成されている。これらの係止部（４２）（４２）は、雌ねじ片（４）が図３の（Ｂ）の前記近接位置に位置されたときに、支柱（２）側の係止用切欠部（２４）に嵌まり込んで雌ねじ片（４）を位置決め固定する一方、雌ねじ片（４）が図３の（Ａ）に示す離間位置に押し込まれると、上記係止用切欠部（２４）から脱出して上記の係合を解き、雌ねじ片（４）の上下方向の移動を自由化するものである。 On the other hand, the female screw piece (4) is formed with a thin-walled recess (41) (41) on the front side of the wings on both sides. As a result, a pair of locking portions (42) and (42) are formed above and below the recessed portion (41). These locking portions (42) and (42) are provided with locking notches (24) on the support (2) side when the female thread piece (4) is positioned at the close position in FIG. And the female thread piece (4) is positioned and fixed, and when the female thread piece (4) is pushed into the separation position shown in FIG. 3 (A), it escapes from the locking notch (24). The above engagement is released, and the movement of the female screw piece (4) in the vertical direction is freed.
従って、支柱（２）側の上記係止用切欠部（２４）は、４本の支柱（２）の全てについて、その第３折曲縁（２２ｃ）の同じ高さ位置に、かつ支柱の長さ方向に所定間隔おきに多数個設けられているものである。 Accordingly, the locking notch (24) on the column (2) side is the same height position of the third bent edge (22c) of all four columns (2) and the length of the column. A large number are provided at predetermined intervals in the vertical direction.
支柱（２）の第３折曲縁（２２ｃ）は、支柱（２）の側縁端面に手指が触れて負傷する危険を回避するために、また支柱（２）の外観体裁を一層良好なものとするために、これを設けたものとすることが望ましいが、必ずしも必要とされるものではない。従って、この第３節曲縁（２２Ｃ）を設けない場合には、第２折曲縁（２２ｂ）に上記切欠部（２４）に代わる切欠部、あるいは係止用の孔を形成して、雌ねじ片（４）の対応部位に設けた突起状等の係止部を係合させるものとしても良い。 The third bent edge (22c) of the support post (2) is for improving the appearance of the support post (2) in order to avoid the risk of injury due to the fingers touching the side edge of the support post (2). For this reason, it is desirable to provide this, but it is not always necessary. Accordingly, when the third bent edge (22C) is not provided, a notch portion instead of the notch portion (24) or a locking hole is formed on the second bent edge (22b), and the female screw It is good also as what engages engaging parts, such as a projection, provided in the corresponding part of piece (4).
棚板（１）の四隅部の周側壁（１２）内側には、コーナー止着片（５）が配置されている。このコーナー止着片（５）は、ポリアミド樹脂等の硬質合成樹脂製または金属製であり、上記隅部に対応する略Ｌ字状に形成され、直角に伸びた両腕部の外面を棚板（１）の隅部の周側壁内面に当接させて配置されている。 Corner fastening pieces (5) are arranged inside the peripheral side walls (12) at the four corners of the shelf board (1). This corner fastening piece (5) is made of hard synthetic resin such as polyamide resin or metal, is formed in a substantially L shape corresponding to the corner portion, and the outer surfaces of both arms extending at right angles are shelf plates. It arrange | positions in contact with the peripheral side wall inner surface of the corner of (1).
そして、コーナー止着片（５）と対応位置の前記雌ねじ片（４）とが、それらの間に棚板（１）の隅部周側壁（１２）を挾んで止めねじ（３）で締結固定されている。止めねじ（３）は、コーナー止着片（５）の屈折部中央に穿設された透孔（５１）を貫通して、支柱（２）内の雌ねじ片（４）にねじ込まれることにより、上記隅部周側壁（１２）を雌ねじ片（４）とコーナー止着片（５）との間に強く挾着せしめるものとしている。しかし、これだけでは棚板（１）の固定は未だ不十分である。 Then, the corner fastening piece (5) and the female screw piece (4) at the corresponding position are fastened and fixed by the set screw (3) with the corner peripheral side wall (12) of the shelf board (1) sandwiched between them. Has been. The set screw (3) passes through the through hole (51) drilled in the center of the refracting portion of the corner fastening piece (5) and is screwed into the female screw piece (4) in the support column (2). The corner peripheral side wall (12) is firmly attached between the female screw piece (4) and the corner fastening piece (5). However, the shelf board (1) is still insufficiently fixed by this alone.
そこで、この実施例においては、独自の工夫として、上記コーナー止着片（５）に係止突片（５２）を設けて、棚板（１）の取付強度の確保と、棚のぐらつきの防止の万全をはかりうるものとしている。 Therefore, in this embodiment, as a unique device, a locking protrusion (52) is provided on the corner fastening piece (5) to secure the mounting strength of the shelf board (1) and to prevent the wobbling of the shelf. It is supposed to be able to measure all possible.
即ち、コーナー止着片（５）には、直角にのびた左右の両腕部の外面に、それぞれ上下に離間して、互いに１対をなす合計４個の直角三角形の係止突片（５２）が一体に突設されている。これらの係止突片（５２）は、コーナー止着片（５）の屈折部方向に向いた面を上記外面から直角に立ち上げて垂直面（５２ａ）とした直角三角形に形成されたものである。 That is, the corner fastening piece (5) has a total of four right-angled triangular protrusions (52) which are spaced apart from each other on the outer surfaces of the left and right arms extending at a right angle. Are projecting together. These locking protrusions (52) are formed in a right-angled triangle with the surface facing the direction of the refracting portion of the corner fastening piece (5) raised from the outer surface at a right angle to form a vertical face (52a). is there.
そして、図２及び図３（Ｂ）に示すように、棚の組立状態において、上記係止突片（５２）は、棚板（１）の隅部周側壁（１２）の対応位置に穿たれた合計４個の貫通孔（１４）を通って棚板（１）の外方に突出され、この突出部が支柱（２）の両側面、即ち互いに直角に位置する第１折曲縁（２２ａ）（２２ａ）の外面に、垂直面（５２ａ）（５２ａ）が当接されたものとなされている。従って、上記係止突片（５２）は、棚板（１）からの突出部分をもって支柱（２）を両側から挾み込んだものとなされている。 As shown in FIGS. 2 and 3 (B), in the assembled state of the shelf, the locking protrusion (52) is drilled at a corresponding position on the corner peripheral side wall (12) of the shelf plate (1). The first bent edge (22a) is projected to the outside of the shelf board (1) through a total of four through holes (14), and the projecting portions are located on both sides of the column (2), that is, at right angles to each other. ) (22a), the vertical surfaces (52a) and (52a) are in contact with each other. Therefore, the said locking protrusion (52) is the thing which swallowed the support | pillar (2) from both sides with the protrusion part from a shelf board (1).
このように、係止突片（５２）が棚板（１）の周側壁（１２）の貫通孔（１４）に通されていることで、棚板（１）はコーナー止着片（５）との相対位置決めがなされ、不本意な棚板（１）の下降ずれが確実に防止される。 Thus, the shelf plate (1) is passed through the through hole (14) of the peripheral side wall (12) of the shelf plate (1), so that the shelf plate (1) is attached to the corner fastening piece (5). And the unintentional downward movement of the shelf board (1) is surely prevented.
また、止めねじ（３）を強く締め付けることによって、雌ねじ部材（４）を介して支柱（２）が開き方向に変形しようとする傾向、即ち第１折曲縁（２２ａ）（２２ａ）が外向きに拡がろうとする傾向を示すが、これに対して上記係止突起（５２）が該第１折曲縁（２２ａ）（２２ａ）を外側から押さえ込んで変形を防ぎ、これとの圧接力が増大されるため、棚板（１）の取付状態が愈々強化されたものになる。 Further, by strongly tightening the set screw (3), the support column (2) tends to be deformed in the opening direction via the female screw member (4), that is, the first bent edges (22a) (22a) are directed outward. On the other hand, the locking projection (52) presses the first bent edges (22a) (22a) from the outside to prevent the deformation, and the pressure contact force increases. Therefore, the mounting state of the shelf board (1) is often reinforced.
更に、上下に離間して互いに１対をなす上記係止突片（５２）（５２）が、支柱（２）を両側面から挾み込んでいるため、棚板（１）に対する支柱（２）の有害なぐらつきが防止される。即ち、棚板（１）の貫通孔（１４）を通って外方に突出した各１対の係止突起（５２）（５２）が、上下に離間した位置で支柱（２）の両側面を挾み込むため、棚板（１）に対する支柱（２）の相対揺動が確実に防止され、組立状態における棚の安定性、堅牢性を向上する。 Furthermore, since the above-mentioned locking protrusions (52) (52) which are paired apart from each other in the vertical direction swallow the column (2) from both sides, the column (2) with respect to the shelf (1) Harmful wobble is prevented. That is, the pair of locking projections (52) (52) protruding outward through the through holes (14) of the shelf board (1) are positioned on both side surfaces of the column (2) at positions spaced vertically. Since the squeezing is carried out, the relative swing of the column (2) with respect to the shelf board (1) is surely prevented, and the stability and robustness of the shelf in the assembled state are improved.
