Description

本願発明は、コーナー支柱で棚板を支持している棚装置に関するものである。なお、本願発明の棚装置は定置式のものには限らず、キャスターを備えたワゴンタイプも含んでいる。   The present invention relates to a shelf apparatus that supports a shelf board with corner posts. The shelf device of the present invention is not limited to a stationary type, but includes a wagon type equipped with casters.

物品を保管したり持ち運んだりするのに平面視四角形でオープン方式の棚装置（スチール棚）が多用されている。この棚装置の一種に、平面視四角形の棚板を平面視Ｌ形のコーナー支柱にボルトで締結したタイプがあり、このタイプでは、棚板の周囲には、コーナー支柱の内面に重なる外壁を折り曲げ形成している。   An open-type shelf device (steel shelf) having a rectangular shape in plan view is often used to store and carry articles. As one type of this shelf device, there is a type in which a rectangular shelf plate in a plan view is fastened with bolts to an L-shaped corner post in plan view. In this type, the outer wall that overlaps the inner surface of the corner post is folded around the shelf plate. Forming.

棚板をコーナー支柱にボルトで固定する方法としては、棚板の外壁に内側から重なる金具を使用して、コーナー支柱と金具とで棚板の外壁をはさみ固定するタイプ（例えば特許文献１参照）と、棚板の外壁をボルト及びナットで直接に締結するタイプとがある。   As a method of fixing the shelf board to the corner column with a bolt, a metal plate that overlaps the outer wall of the shelf board from the inside is used, and the outer wall of the shelf board is sandwiched between the corner column and the metal bracket (see, for example, Patent Document 1). And a type in which the outer wall of the shelf board is directly fastened with bolts and nuts.

後者の直接に締結するタイプは構造が単純である利点があるが、コーナー支柱と棚板との間にガタ付きが生じやすい（すなわち剛性が低い）問題があった。特に、キャスターを有するワゴンタイプの棚装置は、移動させるのに際してコーナー支柱と棚板との締結箇所に慣性力が作用するため、ガタ付きの問題が顕著に現われている。この問題の解決手段として特許文献２には、棚板の外壁（公報の用語では外壁）を外側に折り返すか又は別体の金属板を外壁の外面に溶接することにより、コーナー支柱の側端面に当たる小片を外壁に重ねて設けることが記載されている。   The latter type of direct fastening has an advantage that the structure is simple, but there is a problem that rattling is likely to occur between the corner columns and the shelf board (that is, the rigidity is low). In particular, a wagon type shelf apparatus having casters has a problem of looseness because an inertial force acts on a fastening portion between a corner column and a shelf board when moved. As a means for solving this problem, Patent Document 2 discloses that the outer wall of the shelf plate (the outer wall in the terminology of the publication) is folded outward, or a separate metal plate is welded to the outer surface of the outer wall to hit the side end surface of the corner column. It is described that small pieces are provided on the outer wall.

実開昭４７−９７２２号公報Japanese Utility Model Publication No. 47-9722 特許第３４３７９８８号公報Japanese Patent No. 3437988

特許文献２の発明は、小片の端面をコーナー支柱の側端面に突き当てることによってコーナー支柱の倒れを阻止せんとしたものであり、この場合、小片を溶接によってコーナー支柱の外壁に固着した場合は、小片を外壁に強固に固着できると共に小片として厚い板を使用することができるため、倒れ防止機能（ガタ付き防止機能）は高いが、溶接に手間がかかる問題や、溶接によって塗装が剥げたりひずみが生じたりする問題がある。   The invention of Patent Document 2 is intended to prevent the corner column from falling by abutting the end surface of the small piece against the side end surface of the corner column. In this case, when the small piece is fixed to the outer wall of the corner column by welding, Since the small piece can be firmly fixed to the outer wall and a thick plate can be used as the small piece, the fall prevention function (prevention function with backlash) is high, but the problem is that it takes time to weld and the paint is peeled off or distorted by welding. There is a problem that occurs.

他方、外壁を折り返すことによって小片を形成した場合は、溶接に起因した問題は生じないが、小片はその上端が外壁に繋がっているに過ぎないため、小片の下端に水平方向の荷重（コーナー支柱を倒すような荷重）がかかると小片が変形しやすくなり、このため、強度アップに限度があるという問題があった。 On the other hand, when the small piece is formed by folding the outer wall, there is no problem due to welding, but the small piece has only its upper end connected to the outer wall, so a horizontal load (corner strut) When a load is applied, the small piece is likely to be deformed, and there is a problem that there is a limit to increasing the strength .

本願発明はこのような現状に鑑み成されたもので、より改善された形態の棚装置を提供することを課題とするものである。 The present invention has an object to provide a shelf device such ones been made in view of the current situation, improved Ri good form.

本願発明の棚装置は、４本のコーナー支柱と、前記コーナー支柱で支持された平面視四角形で金属板製の棚板とを備えており、前記棚板は、水平状に広がる基板とこの基板の周囲に折り曲げ形成した外壁とを備えている。そして、請求項１の発明では、前記棚板における外壁の先端に、基板の側に折り返された内壁が、当該内壁と前記外壁との間に空間が空くように連接部を介して一体に形成されており、前記内壁のうち前記連接部と反対側の自由端部は前記外壁に向かって延びるように曲げられている。 Shelving system of the present invention, the four and corner posts of the and a metal plate of the shelf plate in supported viewed square corner post, before Kitanaban includes a substrate extending horizontally And an outer wall formed by bending around the substrate . According to the first aspect of the present invention, the inner wall folded back toward the substrate is integrally formed at the front end of the outer wall of the shelf board via the connecting portion so that a space is provided between the inner wall and the outer wall. The free end of the inner wall opposite to the connecting portion is bent so as to extend toward the outer wall.

請求項２の発明は、請求項１において、前記棚装置の連接部は前記基板と反対側に向いて凸の円弧状に形成されており、前記棚装置における内壁の自由端部は傾斜部になっている。 According to a second aspect of the present invention, in the first aspect, the connecting portion of the shelf device is formed in a convex arc shape facing the side opposite to the substrate, and the free end portion of the inner wall of the shelf device is an inclined portion. It has become.

なお、本願発明の棚板は基板の周囲に外壁を備えているが、棚板は基板から上向きに立ち上がっていても良いし、下向きに垂下していても良い。いうまでもないが、前者では棚板は上向きに開口した姿勢になっており、外壁は物品の落下防止機能も果たしている。   In addition, although the shelf board of this invention is equipped with the outer wall around the board | substrate, the shelf board may stand up from the board | substrate and may hang down downward. Needless to say, in the former case, the shelf plate is in an open-up position, and the outer wall also functions to prevent the articles from falling.

本願発明では、内壁も補強機能を果たして棚板の剛性が高くなるため棚装置全体としてより頑丈な構造にすることができる。 In the present invention, Ru can be more rugged construction as a whole shelving system the rigidity of the shelf plate inner wall also plays a reinforcing function is increased.

The corner strut 1 can be manufactured by bending a strip steel plate, or a commercially available angle material can be used.

棚板２は、水平状に広がる平面視四角形の基板４と、基板４の各辺から上向きに立ち上がっている外壁５と、外壁５の上端に連接した内壁６とから成っており、外壁５をコーナー支柱１に締結している。この点を図２及び図３に基づいて説明する。   The shelf board 2 includes a horizontally-planar rectangular substrate 4, an outer wall 5 rising upward from each side of the substrate 4, and an inner wall 6 connected to the upper end of the outer wall 5. Fastened to the corner post 1. This point will be described with reference to FIGS.

図２のうち（Ａ）はコーナー支柱１と棚板２とを分離した状態での一部破断平面図、（Ｂ）は棚板２をコーナー支柱１に締結した状態での一部破断平面図、図３のうち（Ａ）は棚装置の部分的な正面図、（Ｂ）は（Ａ）のＢ−Ｂ視断面図である。   2A is a partially broken plan view with the corner column 1 and the shelf 2 separated, and FIG. 2B is a partially broken plan view with the shelf 2 fastened to the corner column 1. 3A is a partial front view of the shelf device, and FIG. 3B is a cross-sectional view taken along line BB of FIG.

棚板２の外壁５の端部はコーナー支柱１の側板１ａの内面に重なっており、両者がボルト７及びナット８で締結されている。コーナー支柱１の１枚の側板１ａと棚板２の１枚の外壁５とは１本のボルト７と１個のナット８で締結されており、かつ、コーナー支柱１の各側板１ａと棚板２の各外壁５とは、それぞれ上下２個ずつの位置決め突起９と位置決め穴１０とで位置決めされている。位置決め突起９及び位置決め穴１０は円形に形成されている（多角形又は楕円形でもよい）。   The end of the outer wall 5 of the shelf 2 overlaps the inner surface of the side plate 1 a of the corner column 1, and both are fastened by bolts 7 and nuts 8. One side plate 1a of the corner column 1 and one outer wall 5 of the shelf plate 2 are fastened by one bolt 7 and one nut 8, and each side plate 1a of the corner column 1 and the shelf plate The two outer walls 5 are positioned by two positioning projections 9 and positioning holes 10 respectively. The positioning protrusion 9 and the positioning hole 10 are formed in a circular shape (may be polygonal or elliptical).

本実施形態では、コーナー支柱１の側板１ａに位置決め突起９を突設し、棚板２の外壁５に位置決め穴１０を形成している。また、位置決め突起９及び位置決め穴１０を外壁５の外端部寄りに設けて、ボルト７及びナット８はコーナーの側に配置しているが、ボルト７及びナット８の配置位置や個数、及び、位置決め突起９と位置決め穴１０との個数及び配置位置は、それぞれ任意に設定することができる。例えば、ボルト７を囲う４箇所に位置決め突起９と位置決め穴１０とを設けることも可能である。   In the present embodiment, positioning protrusions 9 are provided on the side plates 1 a of the corner columns 1, and positioning holes 10 are formed in the outer wall 5 of the shelf 2. Further, the positioning projection 9 and the positioning hole 10 are provided near the outer end portion of the outer wall 5, and the bolt 7 and the nut 8 are arranged on the corner side, but the arrangement position and number of the bolt 7 and the nut 8, and The number and arrangement position of the positioning protrusions 9 and the positioning holes 10 can be set arbitrarily. For example, positioning protrusions 9 and positioning holes 10 can be provided at four locations surrounding the bolt 7.

コーナー支柱１や棚板２の厚さは棚装置の大きさや耐荷重の大きさによって異なるが、一般には、棚板２よりもコーナー支柱１が厚くなっている。そして、本実施形態の位置決め突起９は、穴を有するダイスでコーナー支柱１を支持し、その状態でポンチで強打してコーナー支柱１の肉をダイスの穴の箇所に突き出すことで形成されている。コーナー支柱１が棚板２よりも厚いため、コーナー支柱１には、棚板２の位置決め穴１０がすっぽり嵌まる高さの位置決め突起９を形成することができる。   Although the thickness of the corner column 1 and the shelf board 2 differs depending on the size of the shelf device and the load resistance, the corner column 1 is generally thicker than the shelf board 2. And the positioning protrusion 9 of this embodiment is formed by supporting the corner support | pillar 1 with the die | dye which has a hole, and smashing it with a punch in that state, and protruding the meat of the corner support | pillar 1 in the location of the hole of die | dye. . Since the corner column 1 is thicker than the shelf 2, the corner projection 1 can be formed with a positioning projection 9 having a height enough to fit the positioning hole 10 of the shelf 2.

ナット８は棚板２における外壁５の内面に溶接によって固着している。また、図３（Ｂ）に示すように、棚板２の内壁６は外壁５から離反しており、このため、外壁５と内壁６との間にはナット８及びボルト７の端部が隠れる空間が空いている。内壁６のうち外壁５に繋がる連接部１１は本実施形態では略平坦状の姿勢になっている。他方、内壁６の下端部（連接部１１と反対側の自由端部）６ａは、外壁５に向けて傾斜した斜め下向きの傾斜部になっている。なお、棚の連接部１１の各端部は平面視で４５度カットされて傾斜しており、隣り合った連接部１１が互いに突き合わさっている。 The nut 8 is fixed to the inner surface of the outer wall 5 of the shelf board 2 by welding. As shown in FIG. 3B, the inner wall 6 of the shelf 2 is separated from the outer wall 5, so that the end portions of the nut 8 and the bolt 7 are hidden between the outer wall 5 and the inner wall 6. Space is vacant. In the present embodiment, the connecting portion 11 connected to the outer wall 5 of the inner wall 6 has a substantially flat posture. On the other hand, a lower end portion ( a free end portion on the side opposite to the connecting portion 11 ) 6 a of the inner wall 6 is an obliquely downward inclined portion inclined toward the outer wall 5. In addition, each edge part of the connection part 11 of a shelf is cut and inclined by 45 degree | times by planar view, and the adjacent connection part 11 is mutually abutted.

以上の構成において、コーナー支柱１と棚板２とは位置決め突起９と位置決め穴１０によって位置決めされており、棚装置を変形させようとする外力に対して位置決め突起９と位置決め穴１０とが高い抵抗として作用するため、棚装置は高い剛性を保持して頑丈な頑丈な構造になっている。   In the above configuration, the corner column 1 and the shelf board 2 are positioned by the positioning projection 9 and the positioning hole 10, and the positioning projection 9 and the positioning hole 10 have high resistance against the external force that attempts to deform the shelf device. Therefore, the shelf apparatus has a high-rigidity and sturdy structure.

(2).第２〜第４実施形態（図４）
図４では第２〜第４実施形態を示している。このうち（Ａ）に示す第２実施形態では、棚板２の内壁６に、ナット８に嵌まるソケットレンチ１３を抜き差し自在な円形の窓穴１４を空けている。この例では、ナット８は溶接する必要がないため、組み立て作業の能率を向上できると共に加工誤差を吸収できる利点がある。 (2) Second to fourth embodiments (FIG. 4)
