上記請求項１に記載の本発明に係るラックによれば、荷台は、前後一対のビームとこの両ビームを連結するサブビームとから成る枠組み構造でありながら、換言すれば棚板を両ビーム間に固着する版構造でないにもかかわらず、トラス構造体に構成されているので、荷台の前後水平方向の変形を確実に防止し、安全に荷を支持できる安定性のあるラックとして活用できる。又、荷台の両端を支持する左右一対の支柱ユニットどうしを連結するブレースによって、両支柱ユニットを、直角四辺形の左右両平行側辺の相当位置に確実に保持することができ、ラック全体の形態保持機能（正常姿勢での自立機能）を高め、安全に利用できる。換言すれば、上記請求項１に記載の本発明の構成を採用すれば、荷台側のビームの両端に、支柱ユニットの支柱部材に対し横から嵌合する大きなブラケットを溶接し、このブラケットと支柱部材とをピンで結合するような構成、即ち、支柱部材に対する荷台側のビームの上下垂直方向の直角度や前後水平方向の直角度を確保できる構成を採用する必要がなくなり、荷台を構成する前後一対のビームの端部と支柱ユニット側の支柱部材との結合手段として、前記ビーム側に係止爪片を突設させるだけの、荷台に作用する垂直荷重のみを支柱部材に係止爪片を介して伝達する簡単な構成を採用して、ラック全体の構成部品点数を少なくし、大幅なコスト削減を図ることができるのである。 According to the rack according to the first aspect of the present invention, the loading platform has a frame structure composed of a pair of front and rear beams and a sub beam connecting both beams. In other words, the shelf board is placed between the beams. Even though it is not a fixed plate structure, it is constructed as a truss structure, so that it can be used as a stable rack that can reliably support the load safely by preventing deformation of the loading platform in the horizontal direction. In addition, the brace that connects the pair of left and right support units that support both ends of the cargo bed can securely hold both support units at the corresponding positions on the right and left parallel sides of the right-angled quadrilateral. The holding function (independent function in a normal posture) can be enhanced and used safely. In other words, if the configuration of the present invention described in claim 1 is employed, large brackets that are fitted from the side to the support member of the support unit are welded to both ends of the beam on the loading platform side, and the bracket and the support column are welded. as coupling constituting a member with a pin, that gets rid necessary to employ a configuration that can ensure the perpendicularity or perpendicularity of the front and rear horizontal upper and lower vertical loading platform side of the beam relative to the strut member, constituting the loading platform As a means for connecting the end portions of the pair of front and rear beams to the support member on the support unit side, only the vertical load acting on the loading platform is provided on the support member. By adopting a simple configuration that transmits through a piece, the number of components of the entire rack can be reduced, and a significant cost reduction can be achieved.

又、本発明の構成によれば、荷台全体を支柱ユニット側に移動させて、前後一対のビームの端部から突出している係止爪片を支柱部材側の係止孔に差し込み、その後、荷台全体を下げて係止爪片を前記係止孔の下側辺に係合させることにより、荷台と支柱ユニットとが互いに水平方向に離間移動することも前記係止爪片で阻止できる状態に荷台と支柱ユニットとを結合することができる。即ち、荷台全体を組み立てた状態で支柱ユニットに極めて簡単な操作で結合することができ、ラック全体の組立てを容易に行える。 According to the configuration of the present invention, the entire loading platform is moved to the column unit side, and the locking claw pieces protruding from the ends of the pair of front and rear beams are inserted into the locking holes on the column member side, and then the loading platform By lowering the whole and engaging the locking claw piece with the lower side of the locking hole, the loading platform and the support unit can be prevented from moving horizontally apart from each other by the locking claw piece. And the column unit can be combined. That is, the whole rack can be assembled to the support unit by an extremely simple operation, and the entire rack can be easily assembled.

更に、請求項２に記載の本発明の構成によれば、荷台を構成する前後一対のビームを、支柱ユニット側の支柱部材に対し前後水平方向で互いに逆向きに移動させて、ビーム側の係止爪片を支柱部材側の係止孔に差し込み、この後、前後一対のビームを連結手段（サブビームや棚板など）で互いに連結一体化することにより、荷台の組立てと当該荷台の支柱ユニットへの結合とが完了するので、請求項１に記載の構成と比較して、ラック全体の組立てに若干手間がかかるが、支柱ユニットに対する荷台の上下位置が係止爪片と係止孔との係合により確定し、請求項１に記載の構成のように、荷台に上向きに外力が作用しても当該荷台が持ち上げられることがなく、ガタツキのないしっかりとしたラックを組み立てることができる。 Furthermore, according to the configuration of the present invention as set forth in claim 2, the pair of front and rear beams constituting the loading platform are moved in opposite directions in the front-rear horizontal direction with respect to the column members on the column unit side, thereby engaging the beam side. The pawl piece is inserted into the locking hole on the column member side, and then a pair of front and rear beams are connected and integrated with each other by a connecting means (such as a sub beam and a shelf board), thereby assembling the loading platform and connecting it to the column unit of the loading platform. As compared with the configuration of the first aspect , the assembly of the entire rack is somewhat troublesome, but the vertical position of the loading platform with respect to the column unit is related to the relationship between the locking claw pieces and the locking holes. Thus, as in the configuration of the first aspect , even when an external force is applied upward to the cargo bed, the cargo bed is not lifted, and a firm rack without backlash can be assembled.

又、請求項３に記載の構成によれば、ビームの垂直板部に当て付けて固着した別の板材で係止爪片を構成する場合と比較して、ビームと支柱部材以外に全く別部品を使用せずに荷台と支柱ユニットとを結合させることができ、一層のコストダウンを図ることができる。 Further, according to the configuration of claim 3 , compared to the case where the locking claw piece is constituted by another plate material fixed to the vertical plate portion of the beam, it is a completely different part other than the beam and the column member. The carrier and the column unit can be coupled without using the, so that further cost reduction can be achieved.

又、請求項４に記載の構成によれば、ビームを１枚の板材の曲げ加工で構成できるだけでなく、サブビームとの連結も容易な構造とすることができるので、軽量化とコストダウンを図ることができる。 Further , according to the configuration of the fourth aspect , not only can the beam be formed by bending a single plate material, but also the structure can be easily connected to the sub beam, so that weight reduction and cost reduction are achieved. be able to.

又、上記のように本発明の構成によれば、支柱部材に対するビームの上下垂直方向の直角度を確保するための、支柱部材に対し横から嵌合する大きなブラケットがビーム側に設けられていないので、荷台の両端に結合された左右一対の支柱ユニットを、直角四辺形の左右両平行側辺の相当位置に当該荷台によって確実に保持することができない。換言すれば、外力を受けることによりラック全体が左右横方向に平行揺動する恐れがあるが、本発明の構成によれば、左右一対の支柱ユニットのラック背面側の支柱部材どうしを連結するブレースによって、左右一対の支柱ユニットを、直角四辺形の左右両平行側辺の相当位置に確実に保持することができ、ラック全体の形態保持機能（正常姿勢での自立機能）を高め、安全に利用できる。 Further, as described above, according to the configuration of the present invention, a large bracket that is fitted from the side to the support member is not provided on the beam side in order to ensure the perpendicularity of the vertical direction of the beam with respect to the support member. Therefore, the pair of left and right support units coupled to both ends of the loading platform cannot be securely held by the loading platform at the corresponding positions on the right and left parallel sides of the right-angled quadrilateral. In other words, there is a possibility that the entire rack may swing in parallel in the horizontal direction by receiving external force. However, according to the configuration of the present invention , the braces that connect the column members on the rack back side of the pair of left and right column units. Can securely hold a pair of left and right strut units at the corresponding positions on the right and left parallel sides of a right-angled quadrilateral, enhance the form maintenance function (independent function in normal posture) of the entire rack, and use it safely it can.
