Description

本発明は、物品保管用の移動式ラックに関するもので、使用する時は積み重ねることができ、不使用時は内部に同一構造の他のラックを収納する(ネスティングする)ことができる入れ子式ラックに関する。   The present invention relates to a mobile rack for storing articles, and relates to a telescopic rack that can be stacked when used, and can store (nest) other racks of the same structure when not in use. .

移動式でそれ自体どうしで積み重ね可能でネスティング可能な入れ子式ラックは、図1の(a) に示すラックR1を原点として発展し、それから派生して種々のタイプのラックが考案されてきた。しかし、ラックの歴史そのものである図1の(a) に示すようなラックR1は、現在でも根強い需要があり、その主流の一角を形成している。こうした歴史から、現在我が国には膨大な台数のラックR1が保有されているものと考えられる。   Nested racks that are movable, can be stacked between themselves, and can be nested, have been developed starting from the rack R1 shown in FIG. 1 (a), and various types of racks have been devised therefrom. However, the rack R1 as shown in FIG. 1 (a), which is the history of the rack itself, still has a persistent demand and forms one corner of the mainstream. From this history, it is considered that Japan currently has a huge number of racks R1.

図2の(a) はラックR1の正面図、(b) は積載床を除いた状態のラックR1の平面図、(c) はラックR1の右側面図、(d) は(a) のA−A線断面図、(e) はラックR1の背面図である。このラックR1は、左右の前柱1及び後柱2の4本の柱の下端部に矩形枠状の積載床3を設け、左右後柱2,2の上端面に亘って後部上梁4を架設し、前柱1の上端面と後部上梁4の上面とに亘って上レール50を架設し、積載床3の下部には上レール50と対応する位置に下レール60を設けてなるもので、左右前柱1,1の内法間隔Wは左右後柱2,2の外法間隔W1より広く、左右上レール50,50の内法間隔W2は左右後柱2,2の外法間隔W1より広く、更に左右下レール60,60の外法間隔W3は左右前柱1,1の内法間隔Wより狭い。上下レール50,60は夫々等辺山形鋼によって形成されている。また、上レール50には頂角が90度の等辺山形鋼が使用され、下レール60には頂角が90度よりも小さい等辺山形鋼が使用される。左右前柱1,1の前面下端部には前柱1と下レール60との結合を確実にするためのガセットプレート19が設けられ、また後部上梁4の背面側両端部には後部上梁4と上レール50との結合を確実にするためのガセットプレート板51が設けられている。   2 (a) is a front view of the rack R1, (b) is a plan view of the rack R1 with the loading floor removed, (c) is a right side view of the rack R1, and (d) is an A of (a). -A sectional view taken on line A, (e) is a rear view of the rack R1. This rack R1 is provided with a rectangular frame-shaped loading floor 3 at the lower ends of the four pillars, the left and right front pillars 1 and 2, and the rear upper beams 4 are extended over the upper end surfaces of the left and right rear pillars 2 and 2. An upper rail 50 is installed over the upper end surface of the front pillar 1 and the upper surface of the rear upper beam 4, and a lower rail 60 is provided at a position corresponding to the upper rail 50 at the lower part of the loading floor 3. The inner space W between the left and right front columns 1 and 1 is wider than the outer space W1 between the left and right rear columns 2 and 2, and the inner space W2 between the left and right upper rails 50 and 50 is the outer space between the left and right rear columns 2 and 2. The outer distance W3 between the left and right lower rails 60, 60 is wider than W1, and is smaller than the inner distance W between the left and right front columns 1, 1. The upper and lower rails 50 and 60 are each formed of equilateral angle steel. Further, an equilateral angle steel having an apex angle of 90 degrees is used for the upper rail 50, and an equilateral angle steel having an apex angle smaller than 90 degrees is used for the lower rail 60. Gusset plates 19 are provided at the front lower ends of the left and right front columns 1, 1 to ensure the connection between the front column 1 and the lower rail 60, and the rear upper beams 4 are arranged at the rear side ends of the rear upper beams 4. A gusset plate 51 is provided to ensure the connection between the upper rail 50 and the upper rail 50.

上記ラックR1を使用する場合は、同一構造のラックR1を、上下レール50,60を介して積み重ねることができ、積み重ねた時には下段側ラックの上レール50に上段側ラックの下レール60が嵌合して安定する。また、このラックR1の左右上レール50,50の内法間隔W2を左右後柱2,2の外法間隔W1よりも広く(W2>W1)、左右下レール60,60の外法間隔W3は左右前柱1,1の内法間隔Wよりも狭く(W3<W)、従ってW>W3>W2>W1の関係にあるから、不使用時は内部には、一つのラックR1の内部に同じ形状の他のラックR1を、そのラックR1の内部に更に他のラックR1を、と云うように順次挿入して収納できる、即ちネスティングすることができる。   When the rack R1 is used, the rack R1 having the same structure can be stacked via the upper and lower rails 50, 60. When stacked, the lower rail 60 of the upper rack is fitted to the upper rail 50 of the lower rack. And stabilize. Further, the inner modulus interval W2 of the left and right upper rails 50, 50 of the rack R1 is wider than the outer modulus interval W1 of the left and right rear pillars 2, 2 (W2> W1), and the outer modulus interval W3 of the left and right lower rails 60, 60 is Since it is narrower than the internal spacing W between the left and right front pillars 1 and 1 (W3 <W), and therefore has a relationship of W> W3> W2> W1, when not in use, the inside is the same as the inside of one rack R1. Another rack R1 having a shape can be accommodated by sequentially inserting another rack R1 into the inside of the rack R1, that is, nesting.

一方、我が国のような地震多発国では、地震発生時に外力が作用すると、上記のような入れ子式ラック特有の構造、つまりラックの上面側平面視形状及び前面側正面視形状が共にコ字形であるため、構造的なアンバランスから入れ子式でないラックや固定棚に比べて、揺れが大きく、また捩れも大きくなる。一般的に、この種のラックにおいても、地震等による揺れや捩れが大きくなればなるほど、ラックの損壊の危険性が高くなる。従って、ラックを固定棚代わりに使用したり、上下に積み重ねた状態で比較的長期間使用する場合には、整然と配列された入れ子式ラックも、いつ起こるか分からない地震の不安に常に晒されている状態にある。   On the other hand, in an earthquake-prone country such as Japan, when an external force is applied when an earthquake occurs, the structure unique to the nested rack as described above, that is, the top plan view shape and the front view shape of the rack are both U-shaped. For this reason, the swing is large and the twist becomes large as compared with the rack and the fixed shelf which are not nested because of the structural imbalance. In general, even in this type of rack, the greater the shaking or twisting caused by an earthquake or the like, the higher the risk of rack damage. Therefore, when racks are used instead of fixed shelves or used for a relatively long time with being stacked up and down, neatly arranged nested racks are always exposed to earthquake anxieties that do not know when they will occur. Is in a state of being.

そこで、本発明は、上述したような事情に鑑みてなされたもので、一つには、ラック間の連結に重点を置いて、ラックを水平に配列した時に隣接するサイド上梁どうしを簡便に連結できるようにして地震発生時のラックの揺れを少なくし、ラックや保管物品の破損を防止できるようにする一方、上記したように現在でも根強い需要があって、物流業界において膨大な台数が保有されている入れ子式ラックR1を無駄にすることなく、このラックR1を有効に活用できる入れ子式ラックR2を提供することを主たる目的とする。   Therefore, the present invention has been made in view of the circumstances as described above. For one thing, with emphasis on the connection between the racks, when the racks are arranged horizontally, the adjacent side upper beams are simply arranged. While being able to connect to reduce rack shaking during an earthquake and prevent damage to racks and stored items, as mentioned above, there is still a strong demand, and the logistics industry holds a huge number of units. The main object is to provide a telescoping rack R2 that can effectively utilize the rack R1 without wasting the telescoping rack R1.

以上説明したような構成よりなるラックR2の使用において、このラックR2を図12に示すように在来のラックR1の上に積み重ねるには、下側にあるラックR1の上レール50に、その上方よりラックR2の下レール17を嵌合させればよく、この嵌合状態を図13に示す。この場合、上方に位置するラックR2の下レール17の頂角は上レール50の頂角よりも小さいため、上方に位置するラックR2の荷重で下レール17がクッションの役割をして一層安定する。   In the use of the rack R2 having the above-described configuration, the rack R2 is stacked on the conventional rack R1 as shown in FIG. The lower rail 17 of the rack R2 may be fitted, and this fitting state is shown in FIG. In this case, since the apex angle of the lower rail 17 of the rack R2 positioned above is smaller than the apex angle of the upper rail 50, the lower rail 17 acts as a cushion by the load of the rack R2 positioned above and is further stabilized. .

また図12に示すように、ラックR1に積み重ねたラックR2の上に同じラックR2を積み重ねるには、下段側ラックR2における前柱1の上端にある積み重ね用嵌合突起10を、これから積み重ねる上段側ラックR2における前柱1の下端にある積み重ね用嵌合凹部11に嵌合させると共に、この上段側ラックR2における後柱2の下端部を、下段側ラックR2におけるサイド上梁5と後部上梁4とのコーナー部に形成される積み重ね用柱下端部嵌合部16に嵌合させて、後部上梁4の上面4aに支持させればよく、それによって上段側ラックR2は前後及び左右方向、即ち水平方向の移動が制限される。

また、図14に示すように、ラックR1を左右方向に所要間隔に配置して、両ラックR1,R1の対向する上レール50,50間に、ブリッジ用の積載床25を橋架するには、先ず積載床25の左右各端部にある前後一対のコ字形状係止部材26を、図18に示すように、左右各ラックR1の内側の上レール(積載床25に隣接する側の上レール)50に上方より係止すればよい。両ラックR1,R1間に積載床25を橋架した時、積載床25の下面側四隅部に突設してある4つの脚体34…のうち前部側2つの脚体34が各ラックR1の前柱1の真後ろに隣接位置して、積載床25の前方への飛び出しを防止するようになっている。   Further, as shown in FIG. 14, racks R <b> 1 are arranged at a required interval in the left-right direction, and a bridge loading floor 25 is bridged between the upper rails 50, 50 facing both racks R <b> 1, R <b> 1. First, as shown in FIG. 18, a pair of front and rear U-shaped locking members 26 at the left and right ends of the loading floor 25 are connected to the inner rails of the left and right racks R1 (upper rails adjacent to the loading floor 25). ) 50 may be locked from above. When the loading floor 25 is bridged between the racks R1 and R1, the four legs 34 projecting from the four corners on the lower surface side of the loading floor 25 are the two legs 34 on the front side of each rack R1. Adjacent to the back of the front pillar 1, the forward loading of the loading floor 25 is prevented.

上記のようにして両ラックR1,R1の上レール50,50間に積載床25を橋架しただけでは、各ラックR1にラックR2を積み重ねると、ラックR2の内端部側が上がり、外端部側が下がって傾いてしまうことから、この不都合を回避するためにラックR1の外側上レール50に嵩上げライナー28を取り付けるのである。   If the loading floor 25 is simply bridged between the upper rails 50, 50 of the racks R1, R1 as described above, when the rack R2 is stacked on each rack R1, the inner end side of the rack R2 rises and the outer end side becomes In order to avoid this inconvenience, the raising liner 28 is attached to the outer upper rail 50 of the rack R1.

この嵩上げライナー28の取り付けにあたっては、受けレール36の前端側を持ち上げて斜めにした状態でその後端部にある取付部材35をラックR1の外側の上レール50に嵌合させて滑らせながら、図19及び図20に示すように、積み重ね座38をラックR1の後部上梁4上面に載置すると共に、L字形の後端側止め金具39をラックR1の後部上梁4に内側から当接係合させ、そうして受けレール36全体をラックR1の外側上レール50に嵌合させ、図21に示すように受けレール36の前端側にあるL字形の前端側止め金具40をラックR1の外側上レール50の前端面からその下面側に係止させると共に、積み重ね座41をラックR1の前柱1の上端面1aに載置し、サイド位置決めストッパー42をラックR1の前柱1の外側面に係止させる。これにより、嵩上げライナー28は、ラックR1の外側上レール50に対し左右方向、上下方向及び後方向の移動を規制された状態で取り付けられる。   In attaching the raising liner 28, the front end side of the receiving rail 36 is lifted and slanted, and the attachment member 35 at the rear end portion is fitted to the upper rail 50 outside the rack R1 and slid. 19 and FIG. 20, the stacking seat 38 is placed on the upper surface of the rear upper beam 4 of the rack R1, and the L-shaped rear end side stopper 39 is brought into contact with the rear upper beam 4 of the rack R1 from the inside. Then, the entire receiving rail 36 is fitted to the outer upper rail 50 of the rack R1, and the L-shaped front end side stopper 40 on the front end side of the receiving rail 36 is attached to the outer side of the rack R1 as shown in FIG. The upper rail 50 is locked to the lower surface side from the front end face, the stacking seat 41 is placed on the upper end face 1a of the front pillar 1 of the rack R1, and the side positioning stopper 42 is placed outside the front pillar 1 of the rack R1. Engaged to the surface. Thereby, the raising liner 28 is attached to the outer upper rail 50 of the rack R1 in a state in which movement in the left-right direction, the up-down direction, and the rear direction is restricted.

上記のようにして両ラックR1,R1の対向する内側上レール50,50間にブリッジ用積載床25を橋架し且つ両ラックR1,R1の各外側上レール50に嵩上げライナー28を取り付けた後、各ラックR1の上にラックR2を積み重ねる。このラックR1上へのラックR2の積み重ねにあたり、ラックR2の下部の内側下レール17は、図18に示すようにブリッジ用積載床25の受けレール27に嵌合させ、ラックR2の外側下レール17は、図19に示すようにラックR1の外側上レール50に取り付けてある嵩上げライナー28の受けレール36に嵌合させる。   After the bridge loading floor 25 is bridged between the opposed inner upper rails 50, 50 of both racks R1, R1 as described above, and the raised liner 28 is attached to each outer upper rail 50 of both racks R1, R1, A rack R2 is stacked on each rack R1. When stacking the rack R2 on the rack R1, the inner lower rail 17 at the lower part of the rack R2 is fitted to the receiving rail 27 of the bridge loading floor 25 as shown in FIG. 18, and the outer lower rail 17 of the rack R2 is fitted. Is fitted to the receiving rail 36 of the raising liner 28 attached to the outer upper rail 50 of the rack R1 as shown in FIG.

そして、この場合、ラックR2の後柱2の下端面は、図19に示すように、ラックR1の後部上梁4上面に載置された嵩上げライナー28の積み重ね座38の上面で支持され、ラックR2の前柱1の下端面は、ラックR1の前柱の上端面1aに載置された嵩上げライナー28の積み重ね座41の上面で支持されるから、ラックR1の上にラックR2を積み重ねた場合のラックR2側の荷重はレール17,36,50側に負荷されず、ラックR2の前後柱1,2から積み重ね座38,41を介してラックR1の前後柱1,2により支持されることになり、これによって嵩上げライナー28は安定状態に保持される。   In this case, the lower end surface of the rear pillar 2 of the rack R2 is supported by the upper surface of the stacking seat 38 of the raising liner 28 placed on the upper surface of the rear upper beam 4 of the rack R1, as shown in FIG. Since the lower end surface of the front pillar 1 of R2 is supported by the upper surface of the stacking seat 41 of the raising liner 28 placed on the upper end face 1a of the front pillar of the rack R1, the rack R2 is stacked on the rack R1. The load on the rack R2 side is not applied to the rails 17, 36, 50 side, and is supported by the front and rear columns 1 and 2 of the rack R1 from the front and rear columns 1 and 2 of the rack R2 via the stacked seats 38 and 41. Thus, the raising liner 28 is held in a stable state.

It consists of a square square steel pipe.

このブリッジ用積載床45には左右各縦梁48の下面の前端側及び後端側に、下段側ラックR2(1段目ラックR2)のサイド上梁5上面に載置される前端側台座50及び後端側台座51が取り付けられ、この前端側台座50にはサイド上梁5の前端側係合凹部12に係合する係合片52が、また後端側台座51にはサイド上梁5の後端側係合凹部13に係合する係合片53が夫々下向きに突設されている。また、ブリッジ用積載床45の前後横梁46,47の夫々下面両端部には、左右方向位置規制ガイド片54,55が夫々下向きに突設されている。尚、前端側台座50及び後端側台座51は、ブリッジ用積載床45のレベルが上段側ラックR2の積載床3と同じレベルになるようにレベル調整するための台座である。   The bridge loading floor 45 has a front end pedestal 50 mounted on the upper surface of the side upper beam 5 of the lower rack R2 (first rack R2) on the front end side and rear end side of the lower surface of the left and right vertical beams 48. The rear end side pedestal 51 is attached, the front end side pedestal 50 has an engagement piece 52 that engages with the front end side engaging recess 12 of the side upper beam 5, and the rear end side pedestal 51 has a side upper beam 5 Engagement pieces 53 that are engaged with the rear end side engagement recesses 13 project downward. In addition, left and right direction position restricting guide pieces 54 and 55 project downward from both ends of the lower surfaces of the front and rear transverse beams 46 and 47 of the bridge loading floor 45, respectively. The front end side pedestal 50 and the rear end side pedestal 51 are pedestals for adjusting the level so that the level of the bridge loading floor 45 is the same level as the loading floor 3 of the upper rack R2.

そして、上記ブリッジ用積載床45を図12及び図14に示すように2段目ラックR2,R2の積載床3,3間に橋架するには、この積載床45を2段目ラック(上段側)R2,R2の積載床3,3間に配置して、積載床45の左右各縦梁48に設けてある前端側係合片52及び後端側係合片53を、1段目ラック(下段側)R2,R2のサイド上梁5の前端側係合凹部12及び後端側係合部13に係合させるだけで、このブリッジ用積載床45を2段目ラック(上段側)R2,R2の積載床3,3間にこの積載床3と同一レベルに簡単に橋架することができる。   Then, in order to bridge the loading floor 45 for the bridge between the loading floors 3 and 3 of the second racks R2 and R2, as shown in FIGS. 12 and 14, the loading floor 45 is connected to the second rack (upper side). ) The front end side engagement piece 52 and the rear end side engagement piece 53 provided between the left and right vertical beams 48 of the load floor 45 are arranged between the load floors 3 and 3 of R2 and R2, and the first stage rack ( (Lower stage side) By simply engaging the front end side engaging recess 12 and the rear end side engaging part 13 of the side upper beams 5 of R2 and R2, this bridge loading floor 45 can be connected to the second stage rack (upper side) R2, It is possible to easily bridge between the loading floors 3 and 3 of R2 at the same level as the loading floor 3.

また、図14に示す実施形態のように、ラックR1を左右方向に所要間隔に配置して、両ラックR1,R1の上レール50,50間に矩形枠状の積載床25を橋架すると共に、各ラックR1上にラックR2を積み重ねるようにすることにより、ラックR1及びラックR2の使用台数を減らすことができ、それによってラック導入コストの低減を図ることができる。そしてこの場合、積載床25の左右各側端部には、左右各ラックR1の内側の上レール50に上方より係止する係止部材26を設け、この係止部材26上にラックR2の下レール17が嵌合する受けレール27を取り付けておいて、左右各ラックR1の外側の上レール50にラック積み重ね高さ調整用の嵩上げライナー28を配置することにより、積載床3を簡単に両ラックR1,R1間に簡単且つ容易に橋架できると共に、嵩上げライナー28によってラックR1上へのラックR2の積み重ねを的確に行うことができる。   Further, as in the embodiment shown in FIG. 14, the rack R1 is arranged at a required interval in the left-right direction, and a rectangular frame-shaped loading floor 25 is bridged between the upper rails 50, 50 of both racks R1, R1.
