Description

本発明は一種のメタルラックの多重組合せ位置決め装置に係り、特に、棚、支柱、嵌合管及び支柱を結束する結束スリーブで組成されたラックにあって、テーパ形連結シート、テーパ形係止位置決め片及びマッシュルーム型ストッパプラグの設計をラックに応用することで、使用者が簡単に組立られ且つ強固で容易な位置決めが行なえる組合せ構造を提供し、全体構造の実用性を高めるメタルラックの多重組合せ位置決め装置に関する。 The present invention relates to a kind of metal rack multiple combination positioning device, and more particularly to a rack composed of shelves, columns, fitting tubes and bundling sleeves for bundling columns. By applying the single and mushroom-type stopper plug design to the rack, it provides a combined structure that allows the user to easily assemble and perform strong and easy positioning, and multiple combinations of metal racks that enhance the practicality of the overall structure The present invention relates to a positioning device.

一般に周知のラックは図１５、１６に示されるように、複数の環状溝１１１が形成された金属製の支柱１０に、二つの同じ結束スリーブ３０が該支柱１０を結束するように組み合わされ、更に嵌合管４１を利用して複数の棒体が溶接されてなる棚４０が、該支柱１０に組み合わされた結束スリーブ３０に嵌合、位置決めされ、ラックが形成されている。この構造と棚の形成する載置面は使用者が各種物品を放置するのに利用される。且つ支柱１０上端の管口部分にプラグキャップ８０が挿入されて、支柱の中空部分が閉鎖され、また、支柱１０末端に車輪座体９０が螺合されて、全体構造が移動可能とされ、こうしてメタルラックの組合せ構造が形成される。 As shown in FIGS. 15 and 16, a generally known rack is combined with a metal column 10 having a plurality of annular grooves 111 so that two identical bundling sleeves 30 bind the column 10 together. A rack 40 formed by welding a plurality of rods using the fitting tube 41 is fitted and positioned on the binding sleeve 30 combined with the support column 10 to form a rack. This structure and the mounting surface formed by the shelf are used by the user to leave various articles. The plug cap 80 is inserted into the upper end of the column 10 to close the hollow portion of the column, and the wheel seat 90 is screwed to the end of the column 10 so that the entire structure can be moved. A combination structure of metal racks is formed.

このようなメタルラックは、支柱の環状溝に組付けられた結束スリーブに棚の嵌合管が組み合わされ、それは環状溝に位置決めする方式に制限され、且つ結束スリーブによる結束が必要で、棚を自在に延伸し組合せることができず、且つその部品が複雑で、棚が平面の変形や弯曲により一部の角が取り付け後に起き上がり、結束スリーブより脱出し、位置決め不能となりやすい欠点がある。また、このラックの支柱の管口部分は僅かにプラグキャップにより閉じられているだけで、それは装飾効果を具備するだけで、有効な位置決めの機能を有さず、且つ一般に使用者がこのようなラックを運搬する時、習慣的に最上層の棚を持ち上げるが、このとき、棚の嵌合管がプラグキャップを押圧して脱出させてしまうことがあり、ラックの構造強度に影響が生じ、更には棚の嵌合管が支柱より脱出し、ラック構造がゆるみ、ラックとしての機能を達成できなくなることがある。 In such a metal rack, a shelf fitting tube is combined with a bundling sleeve assembled in an annular groove of a support column, which is limited to a method of positioning in the annular groove, and bundling by a bundling sleeve is necessary. There are disadvantages that they cannot be stretched and combined freely, the parts are complicated, the shelf rises after the corners are attached due to deformation or bending of the plane, and it is easy to come out of the binding sleeve and become unpositionable. In addition, the port portion of the rack post is only slightly closed by a plug cap, which has a decorative effect, does not have an effective positioning function, and is generally used by the user. When transporting the rack, the shelf on the top layer is habitually lifted, but at this time, the fitting tube of the shelf may cause the plug cap to be pushed out, which may affect the structural strength of the rack. In some cases, the fitting tube of the shelf comes out of the support column, the rack structure is loosened, and the function as a rack cannot be achieved.

本発明は一種のメタルラックの多重組合せ位置決め装置を提供することを目的とし、それは、テーパ形連結シート、テーパ形係止位置決め片とマッシュルーム型ストッパプラグを、周知の結束スリーブとプラグキャップ等の機能の代わりに採用し、このような機構の組合せにより、全体構造強度を強化し且つ部品を減らして経済的とする効果を達成し、且つその具備する多様な組立方式と取り付けに便利な特性により、使用者に良好な位置決め効果を提供し、実用効果が高いメタルラックの多重組合せ位置決め装置であるものとする。 It is an object of the present invention to provide a kind of metal rack multiple combination positioning device, which includes a tapered connecting sheet, a tapered locking positioning piece and a mushroom-type stopper plug, and functions such as a well-known binding sleeve and plug cap. Adopting instead of the above, the combination of such mechanisms achieves the effect of strengthening the overall structural strength and reducing the number of parts and making it economical, and with the various assembly methods and convenient characteristics that it has, It is a metal rack multiple combination positioning device that provides a good positioning effect to the user and has a high practical effect.
