上記構成のラックの棚用フレームでは、サブビーム材に上向きの外力が作用したとき、当該サブビーム材の突出部の前記係止片がビーム材側の前記係止孔から上方に脱出してしまうので、この状態でサブビーム材に水平方向の外力が作用すると、前記係止片が前記係止孔から横側方に外れてしまい、サブビーム材が元の定位置に復帰できなくなり、外れ落ちる恐れがあった。又、持ち上げられたサブビーム材に水平方向の外力が働かない状況であったとしても、サブビーム材が上下に大きくがたつくことになるので不安定であり、安全に使用することが出来ない。 In the rack shelf frame configured as described above, when an upward external force is applied to the sub beam material, the locking piece of the protruding portion of the sub beam material escapes upward from the locking hole on the beam material side. In this state, if a horizontal external force acts on the sub-beam material, the locking piece is released laterally from the locking hole, and the sub-beam material cannot be returned to the original fixed position and may fall off. . Even if a horizontal external force does not act on the lifted sub-beam material, the sub-beam material is unstable because it largely shakes up and down, and cannot be used safely.

又、請求項５に記載の構成によれば、マイナスドライバーなどの身近にある棒状部材をサブビーム材浮上り制限部材の本体部の切欠き溝部に挿入して、Ｕ字形の当該本体部を拡げることにより、当該本体部から上向きに突設されている左右一対の前記係止片部を、ビーム材の前記中間水平板部における左右一対の前記切欠き部の内側辺から離脱させることが出来るので、そのまま前記棒状部材（マイナスドライバーなど）を利用してサブビーム材浮上り制限部材を下向きに引き下すだけで、当該サブビーム材浮上り制限部材を取り外すことが出来る。即ち、サブビーム材をビーム材から取り外す場合のサブビーム材浮上り制限部材の取外し作業を、ビーム材の外側から簡単容易に行うことが出来る。 Further, according to the configuration of the fifth aspect, the U-shaped main body portion is expanded by inserting a rod-like member such as a flat-blade screwdriver into the notch groove portion of the main body portion of the sub-beam material lifting limiting member. Thus, the pair of left and right engaging pieces projecting upward from the main body can be separated from the inner sides of the pair of left and right notches in the intermediate horizontal plate portion of the beam material. The sub-beam material lifting restriction member can be removed simply by pulling the sub-beam material lifting restriction member downward using the rod-shaped member (such as a flat-blade screwdriver). That is, it is possible to easily and easily perform the removal work of the sub-beam material lifting restriction member when removing the sub-beam material from the beam material from the outside of the beam material.

Drop into 20a, 20b. As a result, as shown in FIG. 9 and FIG. 10, the sub beam member 3 has the beam member 2a in the horizontal projecting plate portions 15a and 15b of the L-shaped tip portions 17a and 17b of the pair of left and right projecting portions 16a and 16b. 2b is supported at the bottom of the vertical portion of the pair of left and right cutout portions 20a and 20b, and the protrusion of the vertical portion of the cutout portions 20a and 20b is provided in the recessed portions 18a and 18b of the L-shaped tip portions 17a and 17b. The plate part 21 is fitted. Therefore, when the sub-beam material 3 supported horizontally between the pair of front and rear beam members 2a and 2b is moved back and forth in the length direction, one side of the recessed portions 18a and 18b on the sub-beam material 3 side and the beam material. When the protruding plate portion 21 on the 2a, 2b side comes into contact with or the width of the recessed portions 18a, 18b is wide, the one side of the recessed portions 18a, 18b and the protrusion on the beam members 2a, 2b side Before the plate portion 21 comes into contact, one of the end portions 3a and 3b of the main body portion of the sub beam material 3 comes into contact with the vertical projecting plate portion 12a of the beam material 2a or 2b. However, as shown in the drawing, before one of the two end portions 3a and 3b of the main body portion of the sub beam member 3 comes into contact with the vertical projecting plate portion 12a of the beam member 2a or 2b, one side of the recessed portions 18a and 18b is provided. The widths of the recessed portions 18a and 18b are set so that the side and the protruding plate portion 21 on the beam material 2a and 2b side come into contact with each other to restrict the movement of the sub beam material 3 in the length direction. desirable.

次に、図１１及び図１２に示すように、サブビーム材浮上り制限部材２２を組み付ける。このサブビーム材浮上り制限部材２２は、図１３に示すように、中央の本体部２３、この本体部２３の上端から左右両側に水平翼状に突設させた左右一対のストッパー部２４ａ，２４ｂ、及び両ストッパー部２４ａ，２４ｂの基部で本体部２３の上端から上向きに突設させた左右一対の係止片部２５ａ，２５ｂから構成されている。前記本体部２３は、その上側面の中央位置、即ち、左右一対の係止片部２５ａ，２５ｂ間の中央位置から下向きに形成した切欠き溝部２６によってＵ字形に形成されたもので、当該切欠き溝部２６の上端開口部は、左右両側から狭められて狭巾部２６ａを形成している。又、左右一対のストッパー部２４ａ，２４ｂは、下側面が先端側ほど上がるように傾斜して、先端側ほど厚さが薄くなるように形成され、左右一対の係止片部２５ａ，２５ｂは、その先端（上端）が突曲面に形成されると共に、当該先端（上端）の内側には、下がるほど内側に張り出す傾斜面を備えた抜け止め用爪部２７が形成されている。 Next, as shown in FIGS. 11 and 12, the sub-beam material lift limiting member 22 is assembled. As shown in FIG. 13, the sub-beam material lifting limiting member 22 includes a central main body 23, a pair of left and right stoppers 24a and 24b protruding in a horizontal wing shape from the upper end of the main body 23 to the left and right sides, and It is composed of a pair of left and right locking pieces 25a and 25b protruding upward from the upper end of the main body 23 at the base of both stoppers 24a and 24b. The main body portion 23 is formed in a U shape by a notch groove portion 26 formed downward from the center position of the upper side surface thereof, that is, the center position between the pair of left and right engaging piece portions 25a and 25b. The upper end opening of the notch groove 26 is narrowed from both the left and right sides to form a narrow portion 26a. The pair of left and right stopper portions 24a and 24b is formed so that the lower side surface is inclined so as to be raised toward the tip side, and the thickness is made thinner toward the tip side. The pair of left and right locking pieces 25a and 25b are The tip (upper end) is formed in a protruding curved surface, and a retaining pawl portion 27 having an inclined surface that protrudes inward as the lower end (upper end) is formed is formed.

上記構成のサブビーム材浮上り制限部材２２は、例えば、上記各部２３〜２７を備えた断面形状の長尺棒状の合成樹脂成形品を、前記ビーム材２ａ，２ｂの各サブビーム材支持部１９に設けられた左右一対の切欠き部２０ａ，２０ｂの水平部の奥行き長さ（奥行き＝ビーム材２ａ，２ｂの横断方向）より少し短い長さに裁断することにより構成することが出来るが、サブビーム材浮上り制限部材２２の厚さ方向（切欠き溝部２６が貫通する方向）に分割できる金型を使用して一つずつを金型成形することも可能である。この場合は、サブビーム材浮上り制限部材２２の各部２３〜２７の表面に厚さ方向の適当な抜き勾配の傾斜を付けて成形すれば良い。そして各部２３〜２７は、以下に説明する如く使用出来るように大きさや形状が設定されるものである。 The sub-beam material lifting limiting member 22 having the above-described configuration is provided with, for example, a long bar-shaped synthetic resin molded article having the above-described portions 23 to 27 on each sub-beam material support portion 19 of the beam materials 2a and 2b. It can be configured by cutting to a length slightly shorter than the depth length of the horizontal portion of the pair of left and right cutout portions 20a and 20b (depth = transverse direction of the beam materials 2a and 2b). It is also possible to mold one by one using a mold that can be divided in the thickness direction of the restriction member 22 (direction in which the notch groove portion 26 penetrates). In this case, the surface of each portion 23 to 27 of the sub-beam material lift limiting member 22 may be formed with an appropriate draft angle in the thickness direction. And each part 23-27 is set as a magnitude | size and a shape so that it can be used as it demonstrates below.

即ち、図１４〜図１６に示すように、指先で本体２３を摘まんだサブビーム材浮上り制限部材２２を、ビーム材２ａ，２ｂの外側（サブビーム材３のある側とは反対側）で溝形板部８の内側に持って行き、ビーム材２ａ，２ｂ側の溝形板部８の垂直板部１１から突出しているサブビーム材３の左右一対のＬ形先端部１７ａ，１７ｂ間に本体部２３を位置させると共に、その左右一対のストッパー部２４ａ，２４ｂを、前記左右一対のＬ形先端部１７ａ，１７ｂの水平張出板部１５ａ，１５ｂとその上方に位置する前記溝形板部８の上側の水平板部９ａとの間に位置させた状態で、本体部２３の側面を溝形板部８の垂直板部１１に隣接させ、係る状態のサブビーム材浮上り制限部材２２の本体部２３の底面を真上に押し上げて、左右一対の係止片部２５ａ，２５ｂの先端の抜け止め用爪部２７を、当該係止片部２５ａ，２５ｂの外側への弾性変形を伴わせて、左右一対の切欠き部２０ａ，２０ｂの水平部（溝形板部８の上側の水平板部９ａに形成された部分）を経由させて溝形板部８の上側の水平板部９ａの上方に突出させ、当該係止片部２５ａ，２５ｂの弾性復帰により先端の抜け止め用爪部２７を、前記切欠き部２０ａ，２０ｂの水平部の内側辺に係合させる。 That is, as shown in FIGS. 14 to 16, the sub-beam material lifting restriction member 22 with the main body 23 gripped by the fingertip is grooved on the outside of the beam materials 2 a and 2 b (on the side opposite to the side where the sub-beam material 3 is provided). The main body between the pair of left and right L-shaped tip portions 17a and 17b of the sub-beam member 3 which is brought inside the shaped plate portion 8 and protrudes from the vertical plate portion 11 of the groove-shaped plate portion 8 on the beam material 2a and 2b side. 23, and a pair of left and right stopper portions 24a and 24b are arranged on the horizontal protruding plate portions 15a and 15b of the pair of left and right L-shaped tip portions 17a and 17b and In a state of being positioned between the upper horizontal plate portion 9a, the side surface of the main body portion 23 is adjacent to the vertical plate portion 11 of the groove-shaped plate portion 8, and the main body portion 23 of the sub-beam material lifting restriction member 22 in such a state is used. Push the bottom side of The retaining claw portion 27 at the tip of each of the portions 25a and 25b is attached to the horizontal portion (channel plate) of the pair of left and right cutout portions 20a and 20b with elastic deformation to the outside of the locking piece portions 25a and 25b. Projecting above the horizontal plate portion 9a on the upper side of the groove-shaped plate portion 8 via a portion formed on the horizontal plate portion 9a on the upper side of the portion 8 and elastically returning the locking piece portions 25a, 25b Is engaged with the inner side of the horizontal portion of the notches 20a and 20b.

上記の左右一対の係止片部２５ａ，２５ｂにおける抜け止め用爪部２７を切欠き部２０ａ，２０ｂの水平部の内側辺に係合させるときの当該係止片部２５ａ，２５ｂの外側への弾性変形は、本体部２３に対する当該係止片部２５ａ，２５ｂの外側への弾性変形、又はＵ字形の本体部２３の弾性に抗する外側への拡がり変形、若しくはその両方の組み合わせによって行われる。 When the retaining claw 27 in the pair of left and right locking pieces 25a and 25b is engaged with the inner side of the horizontal portion of the notches 20a and 20b, the locking pieces 25a and 25b are exposed to the outside. The elastic deformation is performed by elastic deformation of the locking piece portions 25a and 25b with respect to the main body portion 23, or outward expansion resistance against the elasticity of the U-shaped main body portion 23, or a combination of both.

以上のようにしてサブビーム材浮上り制限部材２２をビーム材２ａ，２ｂのサブビーム材支持部１９に、左右一対の切欠き部２０ａ，２０ｂを利用して取り付けることにより、図１１Ｂ及び図１２に示すように、本体部２３の上側面及び左右一対のストッパー部２４ａ，２４ｂの上側面がビーム材２ａ，２ｂ側の溝形板部８の上側の水平板部９ａの下側に隣接すると共に本体部２３の一側面が前記溝形板部８の垂直板部１１の外側面に隣接した状態で、左右一対のストッパー部２４ａ，２４ｂが前記切欠き部２０ａ，２０ｂの水平部を下側から蓋をする状態になる。即ち、左右一対の切欠き部２０ａ，２０ｂの水平部から下方に嵌合したサブビーム材３側の左右一対のＬ形先端部１７ａ，１７ｂの水平張出板部１５ａ，１５ｂが上動して、当該切欠き部２０ａ，２０ｂの水平部から上方に抜け出るのを、サブビーム材浮上り制限部材２２の左右一対のストッパー部２４ａ，２４ｂが阻止することになる。このとき当該ストッパー部２４ａ，２４ｂを介してサブビーム材浮上り制限部材２２に上向きの外力が作用することになるが、当該外力は、サブビーム材浮上り制限部材２２の本体部２３の上側面を介して溝形板部８の上側の水平板部９ａで受け止められ、このサブビーム材浮上り制限部材２２を外す方向には作用しない。 11B and FIG. 12 by attaching the sub-beam material lifting restriction member 22 to the sub-beam material support portion 19 of the beam materials 2a and 2b using the pair of left and right cutout portions 20a and 20b as described above. As described above, the upper surface of the main body 23 and the upper surfaces of the pair of left and right stopper portions 24a and 24b are adjacent to the lower side of the horizontal plate portion 9a on the upper side of the groove plate 8 on the beam members 2a and 2b side, and the main body portion. 23 with one side surface adjacent to the outer surface of the vertical plate portion 11 of the channel plate portion 8, the pair of left and right stopper portions 24a and 24b cover the horizontal portion of the notches 20a and 20b from below. It becomes a state to do. That is, the horizontal projecting plate portions 15a and 15b of the pair of left and right L-shaped tip portions 17a and 17b on the side of the sub beam member 3 fitted downward from the horizontal portion of the pair of left and right cutout portions 20a and 20b are moved upward. The pair of left and right stopper portions 24a, 24b of the sub-beam material lifting restriction member 22 are prevented from coming out upward from the horizontal portion of the notches 20a, 20b. At this time, an upward external force acts on the sub-beam material lifting restriction member 22 via the stopper portions 24a and 24b. However, the external force passes through the upper side surface of the main body portion 23 of the sub-beam material floating restriction member 22. Thus, it is received by the horizontal plate portion 9a on the upper side of the groove-shaped plate portion 8, and does not act in the direction of removing the sub-beam material rising restriction member 22.

即ち、サブビーム材浮上り制限部材２２が取り付けられている限り、サブビーム材３をビーム材２ａ，２ｂ間から取り外すことが出来ない。換言すれば、前後一対のビーム材２ａ，２ｂ間に水平に架設されたサブビーム材３は、ビーム材２ａ，２ｂ側の切欠き部２０ａ，２０ｂとサブビーム材３側の突出部１６ａ，１６ｂにおけるＬ形先端部１７ａ，１７ｂとの嵌合により、ビーム材２ａ，２ｂに対して直角向きで定位置に確実に保持されている。又、サブビーム材３側の前記凹入部１８ａ，１８ｂの巾を上記のように設定して構成するときは、サブビーム材３にその長さ方向の外力が作用しても、当該サブビーム材３の前記本体部分の両端部３ａ，３ｂの一方がビーム材２ａ又は２ｂの垂直張出板部１２ａに当接することを避けられ、この当接に起因する塗装やメッキの剥げ落ちが防止出来る。 In other words, as long as the sub-beam material lifting restriction member 22 is attached, the sub-beam material 3 cannot be removed from between the beam materials 2a and 2b. In other words, the sub-beam material 3 installed horizontally between the pair of front and rear beam members 2a and 2b has L in the notches 20a and 20b on the beam materials 2a and 2b side and the protruding portions 16a and 16b on the sub-beam material 3 side. By fitting with the shape tip portions 17a and 17b, the beam members 2a and 2b are securely held in place at a right angle. Further, when the width of the recessed portions 18a and 18b on the sub beam material 3 side is set as described above, even if an external force in the length direction acts on the sub beam material 3, the sub beam material 3 has the One of the two end portions 3a and 3b of the main body portion can be prevented from coming into contact with the vertical projecting plate portion 12a of the beam member 2a or 2b, and coating or plating peeling off due to this contact can be prevented.

ビーム材２ａ，２ｂ間からサブビーム材３を取り外すときは、サブビーム材浮上り制限部材２２を取り外す必要があるが、この場合、図１７及び図１８に示すように、ビーム材２ａ，２ｂの外側（サブビーム材３のある側とは反対側）から棒状部材２８を、サブビーム材浮上り制限部材２２の本体部２３の切欠き溝部２６における狭巾部２６ａ内に圧入させ、Ｕ字形の本体部２３を弾性に抗して左右に拡げるのである。換言すれば、この狭巾部２６ａ内への棒状部材２８の圧入によりＵ字形の本体部２３を弾性に抗して左右に拡げることが出来るように、先端部が長方形断面で且つ先細り楔状に形成された棒状部材２８を使用することになるが、一般的にマイナスドライバーの先端部はそのような形状に形成されているので、専用の棒状部材２８ではなく、汎用のマイナスドライバーを前記棒状部材２８として利用出来るように、前記本体部２３の狭巾部２６ａを含む切欠き溝部２６を形成しておくのが望ましい。又、棒状部材２８の長方形断面の先端部をサブビーム材浮上り制限部材２２の本体部２３の切欠き溝部２６に差し込んだ状態で回転させることにより、当該棒状部材２８の長方形断面の先端部によって前記本体部２３の切欠き溝部２６を左右に拡げることが出来るように、本体部２３を構成することも出来る。 When removing the sub-beam material 3 from between the beam materials 2a and 2b, it is necessary to remove the sub-beam material lifting restriction member 22, but in this case, as shown in FIGS. 17 and 18, the outer side of the beam materials 2a and 2b ( The rod-shaped member 28 is press-fitted into the narrow width portion 26a in the notch groove portion 26 of the main body portion 23 of the sub beam material lifting restriction member 22 from the side opposite to the side where the sub beam material 3 is present, and the U-shaped main body portion 23 is It expands to the left and right against elasticity. In other words, the distal end portion is formed in a rectangular cross section and a tapered wedge shape so that the U-shaped main body portion 23 can be expanded left and right against elasticity by press-fitting the rod-shaped member 28 into the narrow width portion 26a. However, since the tip of the minus driver is generally formed in such a shape, a general-purpose minus driver is used instead of the dedicated rod member 28. It is desirable to form the notch groove portion 26 including the narrow width portion 26a of the main body portion 23 so that the main body portion 23 can be used. Further, by rotating the tip of the rectangular section of the rod-shaped member 28 in a state of being inserted into the notch groove portion 26 of the main body portion 23 of the sub-beam material lifting limiting member 22, the tip of the rectangular section of the rod-shaped member 28 is The main body portion 23 can also be configured so that the notch groove portion 26 of the main body portion 23 can be expanded to the left and right.

上記のように棒状部材２８の先端部の圧入又は回転によりＵ字形の本体部２３を弾性に抗して左右に拡げることにより、左右一対の係止片部２５ａ，２５ｂも左右に開動することになり、その先端の抜け止め用爪部２７が切欠き部２０ａ，２０ｂの水平部の内側辺から外側に外れることになるので、係る状態で棒状部材２８（マイナスドライバー）を下げることにより、本体部２３を左右に拡がった状態のまま引き下げて、左右一対の係止片部２５ａ，２５ｂを切欠き部２０ａ，２０ｂの水平部から下方に引き出すことが出来る。左右一対の係止片部２５ａ，２５ｂが切欠き部２０ａ，２０ｂの水平部から下方に外れたならば、左右一対のストッパー部２４ａ，２４ｂがサブビーム材３側の左右一対のＬ形先端部１７ａ，１７ｂの水平張出板部１５ａ，１５ｂ上に位置する状態で、本体部２３を指先で摘まむなどしてサブビーム材浮上り制限部材２２を外に引き出して取り外すことが出来る。 As described above, the U-shaped main body 23 is expanded left and right against the elasticity by press-fitting or rotating the tip of the rod-shaped member 28, so that the pair of left and right locking pieces 25a and 25b are also moved left and right. Accordingly, the retaining claw portion 27 at the tip of the cutout portion 20a, 20b is detached from the inner side of the horizontal portion of the cutout portion 20a, 20b. The pair of left and right engaging pieces 25a and 25b can be pulled out downward from the horizontal portion of the cutout portions 20a and 20b by pulling down 23 in a state where it is expanded left and right. If the pair of left and right engaging pieces 25a and 25b are moved downward from the horizontal portion of the notches 20a and 20b, the pair of left and right stopper portions 24a and 24b are paired with the left and right L-shaped tip portions 17a on the sub-beam material 3 side. , 17b, the sub-beam material lifting restriction member 22 can be pulled out and removed by, for example, picking the main body 23 with a fingertip in a state of being positioned on the horizontal projecting plate portions 15a, 15b.

サブビーム材浮上り制限部材２２を取り外したならば、サブビーム材３を、その突出部１６ａ，１６ｂの付け根部がビーム材２ａ，２ｂの垂直張出板部１２ａに当接する高さまで平行に持上げた後に水平に回転させて、その両端の突出部１６ａ，１６ｂをビーム材２ａ，２ｂから内側へ離脱させることにより、ビーム材２ａ，２ｂ間からサブビーム材３を取り外すことが出来る。 If the sub-beam material lifting restriction member 22 is removed, the sub-beam material 3 is lifted in parallel until the base portions of the projecting portions 16a and 16b are in contact with the vertical projecting plate portions 12a of the beam materials 2a and 2b. The sub-beam material 3 can be removed from between the beam materials 2a and 2b by rotating horizontally and separating the protrusions 16a and 16b at both ends inward from the beam materials 2a and 2b.

尚、上記のように前後一対のビーム材２ａ，２ｂ間に水平に架設されたサブビーム材３の上に直接荷を載置するときは、当該サブビーム材３の上面、即ち、水平天板部１３の上面は、ビーム材２ａ，２ｂの上面、即ち、上側の外側水平板部７ａの上面とほぼ面一か又は若干低くなるように、サブビーム材３の高さを設定して構成することになるが、前後一対のビーム材２ａ，２ｂ間でサブビーム材３上に荷を支持する棚板材を載置するときは、サブビーム材３の上面がビーム材２ａ，２ｂの上面より棚板材の厚さ分だけ低くなるように構成することが出来る。又、図１１及び図１４〜図１８に示すように、ビーム材２ａ，２ｂの溝形板部８における垂直板部１１の、各サブビーム材支持部１９の左右一対の切欠き部２０ａ，２０ｂ間の中央位置下方に貫通孔２９を設けることが出来る。この貫通孔２９は、例えば図１５に示すように、指先でサブビーム材浮上り制限部材２２の本体部２３を垂直板部１１に沿って押し上げる際の指先による操作空間を広げるのに役立たせることが出来る。 Note that when a load is placed directly on the sub beam member 3 horizontally installed between the pair of front and rear beam members 2a and 2b as described above, the upper surface of the sub beam member 3, that is, the horizontal top plate portion 13 is mounted. The height of the sub-beam material 3 is set so that the upper surface of the sub-beam material 3 is substantially flush with or slightly lower than the upper surfaces of the beam members 2a and 2b, that is, the upper surface of the upper outer horizontal plate portion 7a. However, when a shelf plate material that supports a load is placed on the sub-beam material 3 between the pair of front and rear beam materials 2a and 2b, the upper surface of the sub-beam material 3 is equal to the thickness of the shelf plate material from the upper surfaces of the beam materials 2a and 2b. It can be configured to be as low as possible. Further, as shown in FIGS. 11 and 14 to 18, between the pair of left and right notches 20 a and 20 b of each sub-beam material support portion 19 of the vertical plate portion 11 in the groove-shaped plate portion 8 of the beam materials 2 a and 2 b. A through-hole 29 can be provided below the center position of each. For example, as shown in FIG. 15, the through-hole 29 can be used to widen an operation space by the fingertip when the body portion 23 of the sub-beam material lifting limiting member 22 is pushed up along the vertical plate portion 11 with the fingertip. I can do it.
