上記構成に基づき本発明の動作（機能）を次に説明する。まず図１（ａ）（ｂ）に示すように、段柱（２）の連結凹部（２ａ）を段板（１）の連結板（１ａ）に嵌め込み、交叉して連結する。次に、中心が同軸に並んだ透孔（２ｂ）と連結孔（１ｂ）とに位置決めピンのボルト（３）を同時に挿通し、連結板（１ａ）の内面側でボルト（３）にナット（３ａ）を螺合してナット締めし、段板（１）と段柱（２）とを縦に交叉連結して固定する。そこで、一本の段柱（２）の上下各連結凹部（２ａ）で２枚の上下に配した段板（１）を縦に交叉連結すると、段柱（２）の長さに応じたラック体が形成される。例えば、図１（ｃ）（ｄ）に示すように、上中下各段に位置する方形各段板（１ｘ）（１ｙ）（１ｚ）により３段ラック体を形成する場合、上中各段板（１ｘ）（１ｙ）の各連結孔（１ａ）の一つ置きに段柱（２）を連結して上中各段板（１ｘ）（１ｙ）を縦連結する。次に、中下各段板（１ｙ）（１ｚ）の空き連結孔（１ａ）により中下各段板（１ｙ）（１ｚ）を縦連結すると、上中下３段ラック体（８）が形成される。同様に、他の段板（１）を上下任意に縦連結してラック段数を自在増減できる。 The operation (function) of the present invention will be described below based on the above configuration. First, as shown in FIGS. 1 (a) and 1 (b), the connecting recess (2a) of the step column (2) is fitted into the connecting plate (1a) of the step plate (1), and is connected by crossing. Next, the bolt (3) of the positioning pin is simultaneously inserted into the through hole (2b) and the connecting hole (1b) whose centers are arranged coaxially, and the nut ( 3a) are screwed together and tightened with nuts, and the step plate (1) and the step column (2) are vertically cross-connected and fixed. Therefore, when two upper and lower step plates (1) are vertically cross-connected by the upper and lower connecting recesses (2a) of one step column (2), a rack corresponding to the length of the step column (2) is obtained. The body is formed. For example, as shown in FIGS. 1 (c) and 1 (d), when a three-stage rack body is formed by square step plates (1x) (1y) (1z) positioned at upper, middle, and lower steps, The step pillars (2) are connected to every other connection hole (1a) of the plates (1x) (1y) to vertically connect the upper and middle step plates (1x) (1y). Next, when the middle and lower step plates (1y) and (1z) are vertically connected by the empty connection holes (1a) of the middle and lower step plates (1y) and (1z), the upper, middle, and lower three-tier rack body (8) is formed. Is done. Similarly, the number of rack steps can be freely increased or decreased by vertically connecting other step plates (1) vertically.

図示例では、方形段板（１ｘ）（１ｙ）（１ｚ）の３辺を交叉連結用とし、他の一辺を収納物出し入れ用として開放し、その辺に短めの段柱（２ｆ）を収納物脱落防止用として連結しておく。又、異なる長さの段柱（２）を各段板（１）の空き連結孔（１ａ）に組付けて段板（１）に交叉連結し、段数を上下に適宜、延ばすと共に、所望段を必要な高さに設定して各種高さの収納物に対応できる。同様に、相異なる長さの各種段柱（２）を長さ毎に複数組、予め用意し、それらを選択的に用いて各段高さを収納物や設置場所等、好みに合わせて任意に調節できる。図１（ｅ）（ｆ）は本発明のラック体（９）（１０）を例示し、段柱（２）は簡略に実線で示す。ラック体（９）はラック体（８）と同じ方形ラック体とする一方、ラック体（１０）は円形段板（１ｄ）を用い、従来にない見た目に柔らかく優美な外観の円形ラック体（１０）を形成する。この場合、同様に収納物出入り側に収納物脱落防止用として短めの段柱（２ｆ）を連結することが好ましい。 In the illustrated example, the three sides of the rectangular step plates (1x), (1y), and (1z) are used for cross connection, the other one side is opened for storage and removal, and a short step column (2f) is stored on that side. Connect to prevent falling out. In addition, step columns (2) of different lengths are assembled into the empty connection holes (1a) of the respective step plates (1) and cross-connected to the step plates (1), and the number of steps is appropriately extended up and down as well as desired steps. Can be set to the required height to accommodate various heights. Similarly, multiple sets of different lengths (2) of different lengths are prepared for each length in advance, and the height of each step can be selected according to your preference, such as storage and installation location, by selectively using them. Can be adjusted. 1 (e) and (f) illustrate the rack bodies (9) and (10) of the present invention, and the step column (2) is simply indicated by a solid line. The rack body (9) is the same square rack body as the rack body (8), while the rack body (10) uses a circular step plate (1d) and has a circular rack body (10 ). In this case, similarly, it is preferable to connect a short step column (2f) to the stored item in / out side to prevent the stored item from falling off.

次に、図１（ｇ）（ｈ）に示すように、隣り合った相異なる段板（１）の連結板（１ａ）同士を付き合わせて接触させる。重なった連結孔（１ｂ）に位置決めピンのボルト（３）を同時に挿通し、ナット（３ａ）で締め付け固定して相異なる段板（１）同士を横に平面連結する。円形段板（１ｄ）の場合も同様に連結板（１ｃ）を付き合わせて位置決めピン（３）で連結固定し、相異なる円形段板（１ｄ）同士、平面連結できる。図３（ｉ）〜（ｏ）に示す大小各方形や円形の他、三角形や六角形の各段板（１ｉ）〜（１ｏ）についても各連結板（１ｉａ）〜（１ｏａ）を付き合わせれば、上記同様、相異なる段板（１ｉ）〜（１ｏ）や寸法の異なる段板（１ｉ）〜（１ｏ）同士も平面連結できる。例えば、図５（ａ）（ｂ）（ｃ）に示すように、段板（１ｉｃ）は方形段板（１ｉ）をＬ字形に組み合わせ、段板（１ｋｃ）は４枚の円形段板（１ｋ）を整列させて組み合わせ、段板（１ｍｃ）は６枚の三角形段板（１ｍ）を六角形にそれぞれ組み合わせてなる。Next, as shown in FIGS. 1 (g) and (h), the connecting plates (1a) of the adjacent step plates (1) are brought into contact with each other. Bolts (3) of positioning pins are simultaneously inserted into the overlapping connection holes (1b), and tightened and fixed with nuts (3a) to connect the different step plates (1) to each other in a plane. Similarly, in the case of the circular step plates (1d), the connecting plates (1c) are attached together and connected and fixed by the positioning pins (3), so that different circular step plates (1d) can be connected in a plane. In addition to the large and small squares and circles shown in FIGS. 3 (i) to 3 (o), the triangular plates and hexagonal step plates (1 i) to (1 o) are also associated with the connecting plates (1 ia) to (1 oa). Similarly to the above, different step plates (1i) to (1o) and step plates (1i) to (1o) having different dimensions can be connected in plane. For example, as shown in FIGS. 5A, 5B, and 5C, the step plate (1ic) is a combination of a rectangular step plate (1i) in an L shape, and the step plate (1kc) is formed of four circular step plates (1k). ) Are aligned and combined, and the step plate (1mc) is formed by combining six triangular step plates (1m) into hexagons.

図５（ｄ）に示すように、隣接する方形段板（１ｉ）を横にずらせて平面連結しても良い。上述のように、寸法の異なる段板（１ｉ）〜（１ｏ）同士も同様に平面連結できる。これにより段板（１）の大きさ形状を任意に設定できる。段板（１）の平面連結時、連結部位が段板中間に位置すると、図４（ｎ）（ｌ）（ｍ）の段柱（２ｉ）により段板中間の連結部位を支持し、その部位を安定に支持する。即ち、図１（ｉ）に示すように、段板平面連結時に未使用の空き連結孔（１ｂ）に段柱（２ｉ）の透孔（２ｉａ）を重ねて両孔（１ｂ）（２ｉａ）に位置決めピンのボルト（３）を同時に挿通してナット締めする。段柱（２ｉ）の底端面を段板（１）の上面に載せて段板（１）の中間連結位置を支持する。As shown in FIG. 5 ( d ), adjacent rectangular step plates (1 i) may be shifted in the horizontal direction and connected in plane. As described above, the step plates (1i) to (1o) having different dimensions can be connected in the same manner. Thereby, the magnitude | size shape of a corrugated board (1) can be set arbitrarily. When the connecting portion is located in the middle of the step plate when the step plate (1) is connected to the plane, the connecting portion in the middle of the step plate is supported by the step pillar (2i) of FIGS. 4 (n), (l), and (m). Is supported stably. That is, as shown in FIG. 1 (i), the through hole (2ia) of the step pillar (2i) is overlapped with the unused empty connection hole (1b) at the time of connecting the step plate planes to both holes (1b) (2ia). Insert the bolt (3) of the positioning pin at the same time and tighten the nut. The bottom end surface of the step column (2i) is placed on the upper surface of the step plate (1) to support the intermediate connection position of the step plate (1).

図６右下の（ａ）のラック体（１３）も机上に設置して実書籍や書類等を収納する机上置き用本立てで、筆記、事務用具等も収納整理できる。同図に示すように、ラック体（１３）は各一対の矩形段板（１ｓｂ）（図５（ｆ）参照）を各Ｌ型に平面連結して中上各段とし、下段は段板（１ｓｂ）に短辺幅狭の段板（１ｓｄ）をＬ型に連結し、上中下各段をＬ型段板に形成する。ここで、机上面と接する下段板（１ｓｄ）は机上接地面を中上各段に対して右横側で幅狭とし、ラック体（１３）の設置時の机上占有面積が接地右横側で幅狭となり、その分、机上面積が広くなって机上を効率的に使用できる。この時、下段が幅狭になって姿勢が不安定になるが、Ｌ型の組み合わせで、Ｌ型の前後左右でラック各段が互いにもたれ合ってラック体姿勢の安定化を図る。尚、段板（１ｓｄ）の端部付近に点線の段板（１ｓｅ）を適宜、鉤型に平面連結して上中段板の傾きを支えて姿勢を安定させても良い。図示点線のように、上記同様、段板（１ｓａ）（図５（ｅ）参照）（１ｓｂ）等を平面連結して段板収納面積を増やし、縦連結して上下段数も適宜、増やせる。ラック体（１３）は机上の本立てに限らず、部屋隅のコーナー部等に設置して一般生活用品の収納整理に用いても良い。The rack body (13) shown in the lower right of FIG. 6 is also installed on a desk and can be used for storing books and office tools. As shown in the figure, the rack body (13) has a pair of rectangular step plates (1sb) ( see FIG. 5 (f) ) connected in a plane to each L shape to form upper and lower steps, and the lower step is a step plate ( In step 1sb), a step plate (1sd) having a short short side is connected to the L shape, and the upper, middle, and lower steps are formed in the L shape step plate. Here, the lower plate (1sd) in contact with the desk top surface has a desk grounding surface that is narrow on the right side with respect to the middle and upper levels, and the desk area occupied when the rack body (13) is installed is on the right side of the ground. The width becomes narrower, and the area on the desk is increased accordingly, so that the desk can be used efficiently. At this time, the lower stage becomes narrow and the posture becomes unstable. However, with the L-shaped combination, the rack stages lean against each other on the front, rear, left and right of the L-type to stabilize the rack body posture. Note that a dotted step plate (1se) may be appropriately connected in a planar manner near the end of the step plate (1sd) to support the inclination of the upper and middle step plates to stabilize the posture. Like the dotted line in the figure, similarly to the above, the step plates (1sa) ( see FIG. 5 (e) ) (1sb) and the like are connected in a plane to increase the step plate storage area, and the upper and lower steps can be appropriately increased by connecting them vertically. The rack body (13) is not limited to a book stand on a desk, but may be installed in a corner portion of a room corner or the like to be used for storing and organizing general household items.

図６（ｂ）（ｃ）のラック体（１４）（１５）は植木鉢等の観賞台や商品の陳列台として好適な階段状ラックで、図示例では階段状に形成した上中下三段からなる。まずラック体（１４）は長矩形段板（１ｓｃ）（図５（ｅ）参照）を用い、三枚の長矩形段板（１ｓｃｘ）を長辺側で平面連結して階段一段目の下段とする。次に、下段段板（１ｓｃｘ）の前から二列目段板（１ｓｃｘ）の真上に段板（１ｓｃｙ）を配し、段柱（２）により左右両外側辺側で縦連結して階段二段目の中段とする。その後方長辺側（下段三列目段板（１ｓｃｘ）の前方長辺側真上）に段柱（２ｉ）を縦連結して支持強度を確保する。次に、下段の前から三列目段板（１ｓｃｘ）の真上に段板（１ｓｃｚ）を配し、図１（ｊ）に示す延長段柱（２ｍ）により左右両外側辺及び後方長辺の三辺で縦連結して階段三段目の上段とする。その前方長辺側（下段三列目段板（１ｓｃｘ）の真上）に図４（ｊ）の段柱（２ｅ）を縦連結して支持強度を確保する。The rack bodies (14) and (15) in FIGS. 6 (b) and 6 (c) are stepped racks suitable as ornamental stands such as flower pots and display stands for products. Become. First, the rack body (14) uses a long rectangular step plate (1sc) ( see FIG. 5 (e) ), and the three long rectangular step plates (1scx) are connected in plane on the long side to form the lower step of the first step of the staircase. . Next, a step plate (1 scy) is arranged directly above the second row step plate (1 scx) from the front of the lower step plate (1 scx), and is vertically connected on the left and right outer sides by the step pillar (2). The middle stage of the second stage. After that, the step column (2i) is vertically connected to the longer long side (directly above the front long side of the lower third row step plate (1scx)) to ensure the support strength. Next, a step plate (1 scz) is arranged directly above the third row step plate (1 scx) from the front of the lower step, and the left and right outer sides and the rear long side are extended by the extended step columns (2 m) shown in FIG. The three stairs are vertically connected to form the upper stage of the third step of the stairs. The step pillar (2e) of FIG. 4 (j) is vertically connected to the front long side (directly above the lower third row step plate (1scx)) to ensure the support strength.

ここで、上段（三段目）の段板（１ｓｃｚ）に三辺で縦連結する図１（ｊ）の延長段柱（２ｍ）は中段段板（１ｓｃｙ）を平面連結位置で支持する段柱（２ｉ）を連結筒（２ｎ）により二本同軸に連結して延長したもので、筒内中間にスペーサ柱（２ｐ）を介在させて固定する。スペーサ柱（２ｐ）の高さ（Ｄｘ）は次式より決まる。まず図４（ｃ）に示すように、段柱（２）の凹部（２ａ）の高さ（Ｄｏ）、上下凹部間距離（Ｈｏ）、図１（ｉ）に示す連結板（１ａ）の連結孔（１ｂ）の孔中心から下端及び上端までの各距離をそれぞれ（Ｈａ）（Ｈｂ）、図１（ｊ）に示す段柱（２ｉ）の透孔中心から下端までの距離（Ｈｘ）とする。上記高さ（Ｄｘ）の算出に際し、段柱（２）による段板（１）の各段縦連結時の各段板連結孔（中心）間の距離（Ｒ）を基点に考察する。 Here, the extension step column (2m) of FIG. 1 (j) that is vertically connected to the upper step (third step) step plate (1scz) at three sides is the step column that supports the middle step plate (1scy) at the plane connection position. (2i) is extended by connecting two coaxially by a connecting cylinder (2n), and is fixed with a spacer column (2p) interposed in the middle of the cylinder. The height (Dx) of the spacer column (2p) is determined by the following equation. First, as shown in FIG. 4 (c), the height (Do) of the recess (2a) of the step column (2), the distance (Ho) between the upper and lower recesses, and the connection of the connecting plate (1a) shown in FIG. 1 (i). Respective distances from the hole center to the lower end and the upper end of the hole (1b) are (Ha) and (Hb), respectively, and the distance (Hx) from the through hole center to the lower end of the step column (2i) shown in FIG. . In calculating the height (Dx), the distance (R) between the step plate connection holes (center) when the step plate (1) is connected vertically by the step column (2) is considered as a base point.

まず図１（ｄ）に示すように、まず一段（下段）と二段（中段）の各連結孔間の距離（Ｒａ）、二段と三段（上段）の同距離（Ｒｂ）、一段から三段までの同距離（Ｒｃ）とすると、次式が成り立つ。
Ｈｘ＝Ｈｏ＋Ｈａ、Ｒａ＝Ｈｂ＋Ｈｏ＋Ｈａ＝Ｈｂ＋Ｈｘ、
Ｒｂ＝Ｈｂ＋Ｈｏ＋Ｈａ＝Ｈｂ＋Ｈｘ、Ｒｃ＝Ｒａ＋Ｒｂ＝２（Ｈｂ＋Ｈｘ）
一方、図１（ｊ）に示すように、高さ（Ｄｘ）のスペーサ柱（２ｐ）を介して２本の段柱（２ｉ）を図示異方向に同軸連結した延長段柱（２ｍ）を一段と三段の各段板（１）に縦連結した場合、段柱（２ｍ）の上下各透孔間距離（Ｒｄ）は、Ｒｄ＝２Ｈｘ＋Ｄｘとなる。Ｒｃ＝Ｒｄより２（Ｈｂ＋Ｈｘ）＝２Ｈｘ＋Ｄｘとなり、Ｄｘ＝２Ｈｂを得る。First, as shown in FIG. 1 (d), first, the distance (Ra) between the connection holes of the first stage (lower stage) and the second stage (middle stage), the same distance (Rb) of the second stage and the third stage (upper stage), from the first stage. Assuming the same distance (Rc) up to three stages, the following equation holds.
Hx = Ho + Ha, Ra = Hb + Ho + Ha = Hb + Hx,
Rb = Hb + Ho + Ha = Hb + Hx, Rc = Ra + Rb = 2 (Hb + Hx)
On the other hand, as shown in FIG. 1 (j), an extended step column (2m) in which two step columns (2i) are coaxially connected in different directions through a spacer column (2p) having a height (Dx) is further formed. When vertically connected to the three step plates (1), the distance (Rd) between the upper and lower through holes of the step column (2m) is Rd = 2Hx + Dx. From Rc = Rd, 2 (Hb + Hx) = 2Hx + Dx, and Dx = 2Hb is obtained.

次に、一段と二段に連結する段柱（２）は同じ高さで、二段と三段に連結する段柱（２）の上下凹部間距離を（Ｈｏ）から（Ｈｏａ）に変えると、それに対応して段柱（２ｉ）の距離（Ｈｘ）は（Ｈｘａ）に変わる。そこで、二段と三段の各連結孔間の距離を（Ｒｅ）、相異なる距離（Ｈｏ）（Ｈｏａ）の各段柱（２）を段板（１）に縦連結した時、一段から三段までの各連結孔間距離を（Ｒｆ）とすると、次式が成り立つ。
Ｈｘａ＝Ｈｏａ＋Ｈａ
Ｒｅ＝Ｈｂ＋Ｈｏａ＋Ｈａ＝Ｈｂ＋Ｈｘａ
Ｒｆ＝Ｒａ＋Ｒｅ＝（Ｈｂ＋Ｈｘ）＋（Ｈｂ＋Ｈｘａ）＝２Ｈｂ＋（Ｈｘ＋Ｈｘａ）
一方、段柱（２ｍ）の上下各透孔間距離（Ｒｇ）は、Ｒｇ＝Ｈｘ＋Ｄｘ＋Ｈｘａとなる。Ｒｆ＝Ｒｇより２Ｈｂ＋（Ｈｘ＋Ｈｘａ）＝Ｈｘ＋Ｄｘ＋Ｈｘａとなり、
Ｄｘ＝２Ｈｂを得る。Next, when the step pillars (2) connected to the first and second steps are the same height, and the distance between the upper and lower recesses of the step columns (2) connected to the second and third steps is changed from (Ho) to (Hoa), Correspondingly, the distance (Hx) of the step column (2i) changes to (Hxa). Thus, when the distance between the two-stage and three-stage connecting holes is (Re) and the step pillars (2) having different distances (Ho) and (Hoa) are vertically connected to the step board (1), the distance from the first stage to the third stage is three. When the distance between the connecting holes to the step is (Rf), the following equation is established.
Hxa = Hoa + Ha
Re = Hb + Hoa + Ha = Hb + Hxa
Rf = Ra + Re = (Hb + Hx) + (Hb + Hxa) = 2Hb + (Hx + Hxa)
On the other hand, the distance (Rg) between the upper and lower through holes of the step column (2 m) is Rg = Hx + Dx + Hxa. From Rf = Rg, 2Hb + (Hx + Hxa) = Hx + Dx + Hxa,
Dx = 2Hb is obtained.

図１（ｋ）において段柱（２）の縦連結に図４（ｒ）（ｓ）の鉤型仲介板（７）を用いる。仲介板（７）は連結板（１ａ）の代替となって同一縦幅（Ｈａ＋Ｈｂ）とし、図４（ｕ）の連結孔（１ｂ）と同径の３個の孔（７ａ）を穿設する。図示例では、中央孔（７ａ）に段柱（２）の下部凹部（２ａ）を連結して上部凹部を三段目段板（１）に連結する。左右各孔（７ａ）に段柱（２）の上部凹部（２ａ）を連結して下部凹部を一段目段板（１）に連結する。図４（ｔ）の仲介板（７ｂ）のように、鉤型をコ字型にしても良い。In FIG. 1 (k), the vertical intermediary plate (7) shown in FIGS. 4 ( r ) and ( s ) is used for the vertical connection of the column (2). The intermediate plate (7) has the same vertical width (Ha + Hb) as an alternative to the connecting plate (1a), and has three holes (7a) having the same diameter as the connecting hole (1b) in FIG. 4 ( u ). . In the illustrated example, the lower recess (2a) of the step column (2) is connected to the central hole (7a), and the upper recess is connected to the third step plate (1). The upper recess (2a) of the step column (2) is connected to the left and right holes (7a), and the lower recess is connected to the first step plate (1). As shown in FIG. 4 mediated plate (t) (7b), it may be a hook-shaped in a U-shape.

次に、距離（Ｈｏ）の段柱（２）を上中下各段板（１）に縦連結した時、一段表面から二段連結孔（中心）までの距離を（Ｒｈ）（図１（ｉ）参照）、二段連結孔（中心）から三段連結孔（中心）までの距離を（Ｒｉ）、一段表面から三段連結孔（中心）までの距離を（Ｒｊ）とすると、次式が成り立つ。
Ｒｈ＝Ｈｘ＝Ｈｏ＋Ｈａ、Ｒｉ＝Ｈｂ＋Ｒｈ＝Ｈｂ＋Ｈｘ、
Ｒｊ＝Ｒｈ＋Ｒｉ＝Ｈｘ＋Ｈｂ＋Ｈｘ＝２Ｈｘ＋Ｈｂ、
次に、図１（１）に示すように、高さ（Ｄｙ）のスペーサ柱（２ｒ）を介して２本の段柱（２ｉ）を同軸連結した延長段柱（２ｑ）を段板（１）に連結して段板表面上に支持した場合、段柱（２ｑ）の最下端から最上透孔までの距離を（Ｒｋ）、段柱（２ｉ）の透孔中心から上端面までの高さを（Ｈｃ）とすると、次式が成り立つ。
Ｒｋ＝２Ｈｘ＋Ｈｃ＋Ｄｙ
Ｒｊ＝Ｒｋより２Ｈｘ＋Ｈｂ＝２Ｈｘ＋Ｈｃ＋Ｄｙとなり、Ｄｙ＝Ｈｂ−Ｈｃを得る。Next, when the step column (2) of the distance (Ho) is vertically connected to the upper, middle, and lower step plates (1), the distance from the first step surface to the second step connection hole (center) is (Rh) (FIG. 1 ( i)), the distance from the two-stage connecting hole (center) to the three-stage connecting hole (center) is (Ri), and the distance from the first stage surface to the three-stage connecting hole (center) is (Rj), Holds.
Rh = Hx = Ho + Ha, Ri = Hb + Rh = Hb + Hx,
Rj = Rh + Ri = Hx + Hb + Hx = 2Hx + Hb,
Next, as shown in FIG. 1 (1), an extended step column (2q) in which two step columns (2i) are coaxially connected via a spacer column (2r) having a height (Dy) is connected to a step plate (1 ) And supported on the surface of the step plate (Rk), the distance from the bottom end of the step column (2q) to the uppermost through hole, and the height from the center of the step column (2i) to the upper end surface. Is (Hc), the following equation holds.
Rk = 2Hx + Hc + Dy
From Rj = Rk, 2Hx + Hb = 2Hx + Hc + Dy, and Dy = Hb−Hc is obtained.

次に、一段と二段に連結する段柱（２）の高さは同じとし、二段と三段に連結する段柱（２）の上下凹部間距離を（Ｈｏ）から（Ｈｏｂ）に変えると、それに対応して段柱（２ｉ）の距離（Ｈｘ）は（Ｈｘｂ）に変わる。一方、相異なる距離（Ｈｏ）と（Ｈｏｂ）の各段柱（２）を段板（１）に縦連結した時、一段表面から二段連結孔（中心）までの距離は（Ｒｈ）で、二段連結孔（中心）から三段連結孔（中心）までの距離を（Ｒｌ）、一段表面から三段連結孔（中心）までの距離を（Ｒｍ）とすると、次式が成り立つ。
Ｈｘｂ＝Ｈｏｂ＋Ｈａ、Ｒｈ＝Ｈｘ＝Ｈｏ＋Ｈａ、Ｒｌ＝Ｈｂ＋Ｈｘｂ、
Ｒｍ＝Ｒｈ＋Ｒｌ＝Ｈｘ＋Ｈｂ＋Ｈｘｂ
一方、図１（１）の段柱（２ｑ）において段柱（２ｉ）の各凹部間距離が（Ｈｏ）と（Ｈｏｂ）からなる場合、最下端から最上透孔までの距離を（Ｒｎ）とすると、
Ｒｎ＝（Ｈｘ＋Ｈｃ＋Ｄｙ）＋Ｈｘｂとなる。
Ｒｍ＝ＲｎよりＨｘ＋Ｈｂ＋Ｈｘｂ＝Ｈｘ＋Ｈｃ＋Ｄｙ＋Ｈｘｂとなり、
Ｄｙ＝Ｈｂ−Ｈｃを得る。Next, assuming that the height of the column (2) connected to the first and second stages is the same, and the distance between the upper and lower recesses of the column (2) connected to the second and third stages is changed from (Ho) to (Hob). Correspondingly, the distance (Hx) of the column (2i) changes to (Hxb). On the other hand, when each step pillar (2) of different distances (Ho) and (Hob) is vertically connected to the step plate (1), the distance from the first step surface to the second step connection hole (center) is (Rh), When the distance from the second stage connection hole (center) to the third stage connection hole (center) is (Rl) and the distance from the first stage surface to the third stage connection hole (center) is (Rm), the following equation is established.
Hxb = Hob + Ha, Rh = Hx = Ho + Ha, Rl = Hb + Hxb,
Rm = Rh + Rl = Hx + Hb + Hxb
On the other hand, in the step column (2q) of FIG. 1 (1), when the distance between the recesses of the step column (2i) is (Ho) and (Hob), the distance from the lowermost end to the uppermost through hole is (Rn). Then
Rn = (Hx + Hc + Dy) + Hxb.
From Rm = Rn, Hx + Hb + Hxb = Hx + Hc + Dy + Hxb,
Dy = Hb−Hc is obtained.

上述よりスペーサ柱（２ｐ）（２ｒ）の各高さ（Ｄｘ）（Ｄｙ）は、
Ｄｘ＝２Ｈｂ、Ｄｙ＝Ｈｂ−Ｈｃで決まる。次に、段柱（２ｍ）に段柱（２ｉ）を増設して延長する場合、図５（ｈ）に示すように、段柱（２ｍ）に高さ（Ｄｚ）のスペーサ柱（２ｓ）を介して凹部間距離（Ｈｏ）の段柱（２ｉ）を同軸連結した段柱（２ｔ）を用いる。この場合、ラック体の一段から三段までの連結孔間距離は（Ｒｃ）、段板（１）に凹部間距離（Ｈｏ）の段柱（２）を縦連結して三段に四段目を増設した場合、三段から四段までの連結孔間距離を（Ｒｏ）、一段から四段までの連結孔間距離を（Ｒｐ）とすると、次式が成り立つ。
Ｒｃ＝Ｒａ＋Ｒｂ＝２（Ｈｂ＋Ｈｘ）、Ｒｏ＝Ｈｂ＋Ｈｘ、
Ｒｐ＝Ｒｃ＋Ｒｏ＝３（Ｈｂ＋Ｈｘ）
一方、段柱（２ｔ）において最下透孔から最上透孔までの距離を（Ｒｑ）とすると、
Ｒｑ＝Ｒｄ＋Ｈｃ＋Ｄｚ＋Ｈｘ＝２Ｈｘ＋Ｄｘ＋Ｈｃ＋Ｄｚ＋Ｈｘとなる。
Ｒｐ＝Ｒｑより３（Ｈｂ＋Ｈｘ）＝２Ｈｘ＋Ｄｘ＋Ｈｃ＋Ｄｚ＋Ｈｘとなり、
Ｄｘ＝２Ｈｂを代入すると、Ｄｚ＝３Ｈｂ−Ｈｃ−Ｄｘ＝Ｈｂ−Ｈｃ＝Ｄｙとなり、

Rk = Hx + Hb + Hx = 2Hx + Hb, Ru = Rk + Hb + Hx = 3Hx + 2Hb,
On the other hand, when the distance from the lowermost end of the step column (2v) to the uppermost through hole in FIG. 5 ( i ) is (Rv), Rv = Rk + Hc + Dv + Hx = 3Hx + Hb + Hc + Dv.
