又、請求項４に記載のように、各段の棚板２Ａ〜２Ｃの内、最上段の棚板２Ａと最下段の棚板２Ｂとの中間に位置する中間段棚板２Ｃの長さ方向両端を支持する棚受け８には、最上段及び最下段の棚板２Ａ，２Ｂの長さ方向両端を支持する棚受け８と同一のものを使用することができる。 Further, the length direction of the intermediate shelf 2C located between the uppermost shelf 2A and the lowermost shelf 2B among the shelf plates 2A to 2C of each step as described in claim 4 As the shelf receiver 8 that supports both ends, the same shelf receiver 8 that supports both ends in the length direction of the uppermost and lowermost shelf plates 2A and 2B can be used.

請求項１に記載の本発明の構成によれば、奥行き方向連結部材と同一レベルの棚板を当該奥行き方向連結部材に設けた棚受け部で支持させるのではなく、当該奥行き方向連結部材とは別にこの奥行き方向連結部材の内側に並列配置された棚受けによって支持させるのであるから、棚受け部を備えていない連結部材、例えば間口方向連結部材と同一構造で長さだけ奥行き方向連結部材に適合するように調整して製作された奥行き方向連結部材を利用してラックを組み立てることができる。又、基本的に各段の棚板は、間口方向の長さを含めて同一サイズ、同一構造に構成されるのが一般的であり、奥行き方向連結部材と同一レベルの棚板を支持する棚受けは、奥行き方向連結部材とは関係なく、支柱の棚受け用係止部に直接係止される係止片を両端に備えるものであるから、奥行き方向連結部材とは異なるレベルで架設される棚板に対応した高さで支柱側に前記棚受け用係止部と同一の棚受け用係止部を設けておきさえすれば、奥行き方向連結部材と同一レベルの棚板を支持するための棚受けを、他のレベルの全ての棚板の棚受けとしてもそのまま転用することができる。換言すれば、奥行き方向連結部材と同一レベルの棚板を含め、ラックの全てのレベルの棚板を支持する棚受けを、請求項４に記載のように同一にすることができる。 According to the configuration of the present invention described in claim 1, instead of supporting the shelf plate at the same level as the depth direction connecting member with the shelf receiving portion provided in the depth direction connecting member, the depth direction connecting member Separately, since it is supported by a shelf holder arranged in parallel inside the depth direction connecting member, it is the same structure as the connecting member that does not have the shelf receiving portion, for example, the front direction connecting member, and fits the depth direction connecting member by the length. The rack can be assembled using the depth-direction connecting member manufactured by adjusting as described above. In general, the shelves at each stage are generally configured to have the same size and the same structure including the length in the frontage direction, and the shelves that support the same level of shelves as the depth direction connecting members. Since the receiver is provided with a locking piece that is directly locked to the shelf receiving locking portion of the support column at both ends irrespective of the depth direction connecting member, it is installed at a level different from that of the depth direction connecting member. As long as the same shelf receiving latching portion as the shelf receiving latching portion is provided on the column side at a height corresponding to the shelf plate, it is necessary to support the same level shelf plate as the depth direction connecting member. The shelf holder can be used as it is as a shelf holder for all other level shelf boards. In other words, the shelf supports that support the shelf boards at all levels of the rack, including the shelf board at the same level as the depth direction connecting member, can be made the same as described in claim 4 .

以上のように、本発明の構成によれば、棚受け部を備えた特殊構造の奥行き方向連結部材が不要になり、ラックを組み立てる部品の種類を減らして大幅なコストダウンを図ることができるに至ったのである。更に、本発明の構成によれば、奥行き方向連結部材の内側に並列する棚受けに当該奥行き方向連結部材と同一レベルの棚板を支持させるものであるにもかかわらず、当該棚板の間口方向の両端の外側に棚受けと奥行き方向連結部材とが並ぶことにはならず、当該棚板の間口方向の両端の外側に奥行き方向連結部材が隣接することになって、見た目の上では、棚受け部を備えた奥行き方向連結部材を使用している構成と同一になり、外観上もすっきりさせることができる。 As described above, according to the configuration of the present invention, there is no need for a depth-direction connecting member having a special structure provided with a shelf receiving portion, and it is possible to reduce the types of parts for assembling the rack and achieve a significant cost reduction. It has come. Furthermore, according to the configuration of the present invention, although the shelf receiver parallel to the inside of the depth direction connecting member supports the same level shelf plate as the depth direction connecting member, The shelf support and the depth direction connecting member are not arranged outside the both ends, and the depth direction connecting member is adjacent to the outside of both ends in the frontage direction of the shelf plate, so that the shelf receiving portion is visually It becomes the same as the structure which uses the depth direction connection member provided with, and can also be made clear in appearance.

尚、請求項２に記載の構成によれば、奥行き方向連結部材と同一レベルの棚板を支持する棚受けの両端係止片が係止される棚受け用係止部と、奥行き方向連結部材の接合板部に設けられた係合部が下向きに係合する被係合部とを、支柱の棚板側の同一側面に領域を分けて配設するのであるから、棚受け用係止部は、支柱の棚板側の側面（実施例の横側板部９ｂ，９ｃ）に設け、奥行き方向連結部材を連結する被係合部は、支柱の内側面（実施例のリップ板部９ｄ，９ｅ）に設ける場合と比較して、支柱に対する奥行き方向連結部材の連結構造を、支柱に対する間口方向連結部材の連結構造と同一にすることができる。従って、請求項３に記載のように、奥行き方向連結部材と間口方向連結部材とを同一構造にする（長さは異なる）ことが容易になる。 In addition, according to the structure of Claim 2, the latching | locking part for shelf holders to which the both-ends locking piece of the shelf holder which supports the shelf board of the same level as a depth direction connection member is latched, and a depth direction connection member Since the engagement portion provided on the joining plate portion of the support plate is engaged with the engaging portion downwardly on the same side surface of the column on the shelf plate side, the shelf receiving locking portion is provided. Is provided on the side of the column on the shelf side (the side plates 9b and 9c in the embodiment), and the engaged portion for connecting the depth direction connecting member is the inner surface of the column (the lip plates 9d and 9e in the embodiment). The connection structure of the depth direction connecting member with respect to the support can be made the same as the connection structure of the frontage direction connecting member with respect to the support as compared with the case where it is provided. Therefore, as described in claim 3, it is easy to make the depth direction connecting member and the frontage direction connecting member have the same structure (the lengths are different).

更に、請求項４に記載の構成によれば、先に説明したように、同一構造、同一サイズの棚受けを全ての棚板の支持に活用することができ、コストダウンを図ることができると共に、ラックの組み立て作業も容易になる。
Furthermore, according to the structure of Claim 4 , as demonstrated previously, while being able to utilize the shelf holder of the same structure and the same size for support of all the shelf boards, while being able to aim at cost reduction The rack assembly work is also facilitated.

It will try to tilt in the vertical vertical direction relative to ˜5B. At this time, at the end portion of each depth direction connecting member 7 that tilts downward relative to the columns 4 A to 5 B, the end surface 25 a of the folded portion 25 on the lower side of the depth direction connecting member 7. Since the depth direction connecting member 7 is tilted relatively downward with respect to the columns 4A to 5B with the contact portion between the lowest part and the lip plate portions 9d and 9e of the columns 4A to 5B as fulcrums, All the connecting portions of the engaged portions 10a to 13c and the engaging portions 27a to 27c in the three vertical rows above and below the lowest portion of the end surface 25a are connected to the columns 4A to 5B of the depth direction connecting member 7. The downward tilt will be suppressed. Further, at the end portion of each depth direction connecting member 7 that tilts relatively upward with respect to the columns 4A to 5B, the uppermost end surface 25a of the folded portion 25 on the upper side of the depth direction connecting member 7 is provided. Since the depth-direction connecting member 7 is tilted relatively upward with respect to the support columns 4A to 5B with the contact portion between the support portion and the lip plate portions 9d and 9e of the support columns 4A to 5B as a fulcrum, the end surface 25a All of the connecting parts of the engaged parts 10a to 13c and the engaging parts 27a to 27c of the upper and lower three stages in the vertical row below the uppermost part of the upper part of the depth direction connecting member 7 with respect to the columns 4A to 5B Will be prevented from tilting.

尚、図示省略しているが、従来周知のように、上記のように枠組み構造体３を組み立てた状態において、間口方向連結部材６及び奥行き方向連結部材７の接合板部２６と各支柱４Ａ〜５Ｂの背側板部９ａ又は横側板部９ｂ，９ｃとを、両者に設けられた貫通孔に係止ピンを着脱自在に挿通して、接合板部２６が支柱４Ａ〜５Ｂに対して上動するのを阻止できるように構成することができる。又、支柱４Ａ〜５Ｂの上下両端部に矩形枠状に連結された間口方向連結部材６及び奥行き方向連結部材７は、それぞれ同一レベルに位置している。 Although not shown in the drawings, as is conventionally known, in the state where the frame structure 3 is assembled as described above, the joint plate portions 26 of the frontage direction connecting member 6 and the depth direction connecting member 7 and the respective columns 4A to 4A. A locking pin is detachably inserted through the back side plate portion 9a or the side plate portions 9b and 9c of 5B through the through holes provided in both, and the joining plate portion 26 moves upward with respect to the columns 4A to 5B. It can be configured to prevent this. Moreover, the frontage direction connecting member 6 and the depth direction connecting member 7 connected to the upper and lower ends of the columns 4A to 5B in a rectangular frame shape are positioned at the same level.

組み立てられた枠組み構造体３には、図７及び図９に示すように、棚受け８が取り付けられる。この棚受け８は、前後対を成す支柱４Ａ，５Ａ間及び支柱４Ｂ，５Ｂ間に、左右２つの棚受け８が同一レベルになるように、適宜取付け高さを選択して取り付けられるが、ラック１の天板に相当する最上段棚板２Ａを支持する棚受け８は、支柱上端部に架設されている奥行き方向連結部材７の内側定位置に取り付けられ、ラック１の底板に相当する最下段棚板２Ｂを支持する棚受け８は、支柱下端部に架設されている奥行き方向連結部材７の内側定位置に取り付けられる。 As shown in FIGS. 7 and 9, a shelf holder 8 is attached to the assembled frame structure 3. The shelf holder 8 is attached by selecting an appropriate mounting height so that the two left and right shelf holders 8 are at the same level between the support posts 4A and 5A and the support posts 4B and 5B forming the front and rear pairs. A shelf receiver 8 that supports an uppermost shelf 2 A corresponding to one top plate is attached to a fixed position on the inner side of the depth-direction connecting member 7 that is installed on the upper end of the column, and is a lowermost step corresponding to the bottom plate of the rack 1.

The side plate portions 9b and 9c are inserted into shelf receiving holes 14 and 15 provided at both upper and lower ends and lowered so that the notches 33 of the engaging pieces 31a and 31b are inserted into the shelf receiving engaging holes 14 and 15 respectively. 15 is fitted to the lower end. In this way, when the shelf holders 8 arranged inside the depth direction connecting members 7 are installed between the support columns 4A and 5A and the support columns 4B and 5B forming the front and rear pairs, the vertical strips of the depth direction connection members 7 are provided. 24 and a belt-like vertical plate 30 of the shelf support 8, a gap is secured as shown in FIG. 9, so that the vertical locking pieces 21 a of the uppermost shelf 2 A and the lowermost shelf 2 B are placed in this gap. 11b is inserted from above as shown in FIG. 11, and both ends in the length direction of the shelf surface plate 19 of the uppermost shelf 2A and the lowermost shelf 2B are supported on the upper side of the belt-like vertical plate 30 of the shelf support 8. . At this time, the belt-like vertical plate 30 of the shelf receiver 8 enters the gap 23 inside the vertical locking pieces 21a and 21b of the uppermost shelf 2A and the lowermost shelf 2B, and the vertical locking pieces 21a and 21b. The both end portions of the stake are inserted into the space between the both end portions of the strip-shaped vertical plate 30 of the shelf support 8 and the support plate 4A, 5A and the side plate portions 9b, 9c of the support posts 4B, 5B. The uppermost shelf 2 A and the lowermost shelf 2 B supported in this manner are surrounded by the frontage direction connecting member 6 and the depth direction connecting member 7, and the shelf board face plate 19 is arranged in the frontage direction. The upper side of the connecting member 6 and the upper side of the depth direction connecting member 7 are located at substantially the same level.

中間棚板２Ｃを支持する棚受け８は、図１２に示すように、前後対を成す支柱４Ａ，５Ａ間及び支柱４Ｂ，５Ｂ間に、各支柱４Ａ〜５Ｂの横側板部９ｂ，９ｃに設けられている中間高さの棚受け係止孔１６を利用して上記の要領で架設し、この棚受け８の帯状垂直板３０に中間棚板２Ｃの垂直係止片２１ａ，２１ｂを引っ掛けるようにして、中間棚板２Ｃの棚板面板１９の長さ方向両端を棚受け８の帯状垂直板３０の上辺に支持させれば良い。このとき、中間棚板２Ｃの垂直係止片２１ａ，２１ｂの両端部は、棚受け８の帯状垂直板３０の両端部と前後対を成す支柱４Ａ，５Ａ及び支柱４Ｂ，５Ｂの横側板部９ｂ，９ｃとの間の空隙部内に入り込んでいる。 As shown in FIG. 12, the shelf receiver 8 that supports the intermediate shelf 2C is provided on the side plates 9b and 9c of the columns 4A to 5B between the columns 4A and 5A and between the columns 4B and 5B forming the front and rear pairs. It is constructed in the above-described manner using the shelf receiving hole 16 of the intermediate height, and the vertical engaging pieces 21a and 21b of the intermediate shelf 2C are hooked on the belt-like vertical plate 30 of the shelf receiver 8. Thus, both ends in the length direction of the shelf plate surface plate 19 of the intermediate shelf plate 2 C may be supported on the upper side of the belt-like vertical plate 30 of the shelf receiver 8. At this time, both end portions of the vertical locking pieces 21a and 21b of the intermediate shelf 2C are the side plates 9b of the columns 4A and 5A and the columns 4B and 5B that form front and rear pairs with both ends of the belt-like vertical plate 30 of the shelf holder 8. , 9c.

各棚受け８は、各支柱４Ａ〜５Ｂの横側板部９ｂ，９ｃに設けられている棚受け係止孔１４〜１６を利用して架設した段階では、その両端の係止片３１ａ，３１ｂの各１つの切欠き３３と各支柱４Ａ〜５Ｂ側の棚受け係止孔１４〜１６とが上下方向に嵌合しているだけであり、各支柱４Ａ〜５Ｂの横側板部９ｂ，９ｃと帯状垂直板３０との間にも比較的大きな空隙があり、操作性を考慮して切欠き３３は開放端（下端）側ほど幅広になるように形成されることもあって、姿勢が不安定なものである。しかしながら、左右対を成す支柱４Ａ，４Ｂ間及び支柱５Ａ，５Ｂ間の間隔は、間口方向連結部材６による連結により一定であるから、各棚板２Ａ〜２Ｃの間口方向の長さ、即ち、垂直係止片２１ａ，２１ｂ間の長さを、これら垂直係止片２１ａ，２１ｂを両側の棚受け８の帯状垂直板３０に係合させたときに、当該垂直係止片２１ａ，２１ｂが両側の棚受け８の帯状垂直板３０と面接触又は近接するように設定しておくことにより、最終的には、棚受け８の姿勢を、棚板２Ａ〜２Ｃの垂直係止片２１ａ，２１ｂにより、その帯状垂直板３０がほぼ垂直になる姿勢に矯正し、棚板２Ａ〜２Ｃ及びその両端を支持する棚受け８を水平方向にがたつきの無い状態とすることができる。 At the stage where each shelf support 8 is installed using the shelf support locking holes 14 to 16 provided in the lateral side plate portions 9b and 9c of the support columns 4A to 5B, the locking pieces 31a and 31b at both ends thereof are connected. Each notch 33 and the shelf support locking holes 14 to 16 on the support columns 4A to 5B are only fitted in the vertical direction, and the side plates 9b and 9c of the support columns 4A to 5B and the belt-like shape. There is a relatively large gap between the vertical plate 30 and the notch 33 is formed so as to be wider toward the open end (lower end) side in consideration of operability, and the posture is unstable. Is. However, since the distance between the left and right columns 4A and 4B and between the columns 5A and 5B is constant due to the connection by the frontage direction connecting member 6, the length in the frontage direction of each shelf plate 2A to 2C, that is, the vertical direction. When the vertical locking pieces 21a and 21b are engaged with the belt-like vertical plates 30 of the shelf supports 8 on both sides, the vertical locking pieces 21a and 21b are arranged on both sides. By setting it so as to be in surface contact with or close to the belt-like vertical plate 30 of the shelf holder 8, finally, the attitude of the shelf holder 8 is determined by the vertical locking pieces 21a and 21b of the shelf plates 2A to 2C. The belt-like vertical plate 30 is corrected to a substantially vertical posture, and the shelf plates 2A to 2C and the shelf support 8 that supports both ends of the shelf plates 2A to 2C can be made in a state free from shakiness in the horizontal direction.

尚、この実施例では、各棚受け８に水平折曲部３２が設けられているので、棚板２Ａ〜２Ｃの棚板面板１９の両端を棚受け８の帯状垂直板３０の上辺で支持すると同時に、棚板２Ａ〜２Ｃの補強用折曲部２０ａ，２０ｂの両端下側面及び補強部材２２ａ，２２ｂの両端下側面を棚受け８の水平折曲部３２上で支持させることができる。勿論、水平折曲部３２は無くとも良いが、水平折曲部３２を設ける場合も、帯状垂直板３０の上辺でのみ棚板２Ａ〜２Ｃを支持させ、水平折曲部３２は、棚受け８の帯状垂直板３０の水平方向の撓み防止（強度アップ）の手段としても良い。 In this embodiment, since the horizontal bent portion 32 is provided in each shelf receiver 8, both ends of the shelf board 19 of the shelf boards 2 A to 2 C are supported by the upper side of the belt-like vertical board 30 of the shelf holder 8. At the same time, the lower side surfaces at both ends of the reinforcing bent portions 20a and 20b of the shelf plates 2A to 2C and the lower side surfaces at both ends of the reinforcing members 22a and 22b can be supported on the horizontal bent portion 32 of the shelf support 8. Of course, the horizontal bent portion 32 may not be provided, but also when the horizontal bent portion 32 is provided, the shelf plates 2A to 2C are supported only on the upper side of the belt-like vertical plate 30, and the horizontal bent portion 32 is the shelf receiver 8. The belt-like vertical plate 30 may be a means for preventing horizontal deflection (increasing strength).

又、被係合部１０ａ〜１３ｃと係合部２７ａ〜２７ｃに設けた相対摺接部１８ａ，１８ｂは、本発明に必須のものでないから、無くとも良い。更に、被係合部及び係合部として、縦一列上下３段の被係合部１０ａ〜１３ｃと係合部２７ａ〜２７ｃを設けたが、上下方向の段数は限定されない（一段でも良い）。 Further, the relative sliding contact portions 18a and 18b provided in the engaged portions 10a to 13c and the engaging portions 27a to 27c are not essential to the present invention and may be omitted. Furthermore, although the engaged portions 10a to 13c and the engaging portions 27a to 27c are provided in three vertical rows as the engaged portions and the engaging portions, the number of vertical steps is not limited (a single step may be used).
