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.
