Description

本発明は、リース、レンタル向けの商品ディスプレイ用パイプ棚の管継手に関し、特に管継手基部に連係する奥行方向のパイプ支持部を水平方向に回動自在な構成とすることにより棚全体を折り畳むことができるようにした折り畳みパイプ棚用管継手に関するものである。   The present invention relates to a pipe joint of a product display pipe shelf for leasing and rental, and in particular, folding a whole shelf by adopting a structure in which a pipe support part in a depth direction linked to a pipe joint base part is rotatable in a horizontal direction. The present invention relates to a pipe joint for folded pipe shelves that can be used.

初期の折り畳みパイプ棚の管継手は、複数のパイプ嵌入部が直角に交わる基部から棚の奥行方向に延設した平板の先端部を半円状に形成し、中心に軸受孔をあけたフランジ型回動支持部を、奥行方向のパイプ嵌入部材に設けた嵌合溝に嵌入し、螺子を回動軸として係合していた。   The pipe joint of the initial folding pipe shelf is a flange type in which the tip of a flat plate extending in the depth direction of the shelf is formed in a semicircular shape from the base where multiple pipe insertion parts intersect at a right angle, and a bearing hole is opened in the center The rotation support portion is fitted into a fitting groove provided in the pipe fitting member in the depth direction, and is engaged with a screw as a rotation shaft.

しかしながら、螺子により係合された管継手は棚全体の美観を損なうため、同型の管継手に螺子止め位置の上下を変えた二種類が必要となり、組み立て時の煩雑さのほか、運搬途中に螺子が緩んで抜け落ちるという欠点があった。   However, since pipe fittings engaged by screws impair the appearance of the entire shelf, two types of pipe fittings of the same type with the upper and lower screwing positions changed are necessary. However, there was a drawback that it loosened and fell off.

そこで、本発明の発明者は、先に、奥行方向のパイプ嵌入部材を上下に二分割して形成する構成とし、一方に回動軸となる円柱状のダボを突設すると共に、他方に軸穴を設けて表面処理を施した後、回動支持部の軸受孔を挿通しプレス機にて圧入して一体とする発明を完成し、特許を取得した。( 特許 第３２０４４９４号 )   Therefore, the inventor of the present invention has a configuration in which the pipe fitting member in the depth direction is divided into two parts in the vertical direction, and a cylindrical dowel serving as a rotating shaft is projected on one side and a shaft on the other side. After providing a hole and performing surface treatment, the invention was completed by inserting the bearing hole of the rotation support portion and press-fitting with a press, and obtained a patent. (Patent No. 3204494)

該特許の管継手は美感上の問題点を解決し、パイプ棚の組み立て時の煩雑さを解消すると共に、管継手の在庫種類の削減を実現したが、１６ミリ角パイプを使用するという寸法上の制約のため圧入強度が十分とは言えず、リース、レンタル使用で頻繁に折り畳み、運送を繰り返すうち圧入部分に緩みが生じ、回動支持部を挟み込む奥行パイプ嵌入部材の嵌合溝が広がることにより、特にパイプ棚の奥行方向への揺れが大きくなるという問題が生じた。   The pipe joint of the patent solved the problem of aesthetics, eliminated the trouble of assembling pipe shelves, and reduced the stock type of pipe joints, but the size of using 16 mm square pipes The press-fitting strength cannot be said to be sufficient due to the restrictions of the above, and the fitting part of the depth pipe fitting member that sandwiches the rotation support part widens as the press-fitting part loosens as it is frequently folded and leased and leased and transported. As a result, there arises a problem that the shaking in the depth direction of the pipe shelf becomes large.

そこで、本発明の発明者は管継手の基部に延設された回動支持部の軸受孔に切欠部を設けて回動軸の装着口とし、奥行パイプ嵌入部材を回動支持部への嵌合溝、及び円柱を装着口よりやや狭く平行に２面削り落とした略平行楕円柱状の回動軸を備えた一体成形型とすると共に、回動軸のズレを防止するために樹脂製の回動軸押さえ部材を用いる構成とし再び特許を申請した。（特許出願２００３−１０４６２１）   Therefore, the inventor of the present invention provides a notch portion in the bearing hole of the rotation support portion extended to the base portion of the pipe joint to provide a mounting shaft for the rotation shaft, and the depth pipe insertion member is fitted to the rotation support portion. The groove and the cylinder are made into an integral mold with a substantially parallel elliptical column-shaped rotation shaft that is scraped off in two parallels slightly narrower than the mounting opening, and a resin rotation is used to prevent displacement of the rotation shaft. We applied for a patent again with a configuration using a moving shaft pressing member. (Patent application 2003-104621)

しかしながら、ここでも折り畳んだパイプ棚を広げる際に、略平行楕円柱状である回動軸の角部が軸受孔の切欠部分とこすれて磨耗し、棚の設置、収納を繰り返すうちスムーズな回動を妨げる原因となることが判明した。   However, when the folded pipe shelf is expanded again, the corners of the pivot shaft, which has a substantially parallel elliptical columnar shape, are worn by rubbing against the notch portion of the bearing hole, and smooth rotation is possible as the shelf is repeatedly installed and stored. It turned out to be a cause of hindrance.

特開２００４−２７０９０８号JP 2004-270908 A 特許第３２０４４９４号Patent No. 3204494

本発明の発明者による従来の技術は、折り畳みパイプ棚用管継手の美感上の問題点を解決し、型種の削減によりパイプ棚の組み立て時の煩雑さを解消すると共に、奥行方向へのユレの防止を実現したが、リース、レンタル使用で頻繁に設置、折り畳んでの収納、運搬を繰り返しても回動部分に磨耗が起こりにくい折り畳みパイプ棚用管継手を提供することが新たな課題となった。   The prior art by the inventor of the present invention solves the problem of aesthetics of the pipe joint for folded pipe shelves, eliminates the complexity when assembling the pipe shelves by reducing the type of the pipe joints, and allows the undulation in the depth direction. However, it is a new issue to provide a pipe joint for folded pipe shelves that is less likely to wear on the rotating part even after repeated installation, folding, storage, and transportation by lease and rental use. It was.

前記課題を解決するため、本発明にかかる折り畳みパイプ棚の管継手は、奥行方向のパイプ部材が間口方向のパイプ部材に対して直角に折り畳み可能な構成とした折り畳みパイプ棚用の管継手であって、複数のパイプ嵌入部が直角に交わる基部から棚の奥行方向に延設した平板状の回動支持部の先端を半円状に形成するとともに、その中心に軸受孔を穿設した管継手本体に、奥行のパイプ嵌入部に形成された嵌合溝に前記回動支持部を回動軸により回動自在に挟んで係合した構造の管継手において、管継手本体１０を回動支持部１３の軸受孔１４の中心から縦方向に二分割し、奥行のパイプ嵌入部１２に一体的に形成されている回動軸２２が該軸受孔１４に嵌入した状態となるように、二分割して形成された管継手本体１０が、合わせ面双方に穿たれた複数の係止穴１６と別部材である複数の係止ピン３０によって合体接合した構造である。 In order to solve the above-described problems, a pipe joint for a folded pipe shelf according to the present invention is a pipe joint for a folded pipe shelf configured such that a pipe member in a depth direction can be folded at right angles to a pipe member in a frontage direction. A pipe joint having a semicircular tip formed at the center of a flat plate-like rotation support portion extending in a depth direction of the shelf from a base portion where a plurality of pipe insertion portions intersect at a right angle, and having a bearing hole at the center thereof In a pipe joint having a structure in which a main body is engaged with a fitting groove formed in a pipe fitting portion in the depth so that the rotary support portion is rotatably held by a rotary shaft, the pipe joint main body 10 is connected to the rotary support portion. 13 bisected in the longitudinal direction from the center of the bearing hole 14 of, as pivot shaft 22 which is integrally formed on the pipe fitting portion 12 of the depth in a state of being fitted in the bearing hole 14, the two-divided The pipe joint body 10 formed by A plurality of locking pins 30 is another member with a plurality of locking holes 16 bored a structure in which coalesced joined.

また、二分割して形成された管継手本体が、さらに合わせ面の一方に穿たれた複数のダボ穴と、合わせ面の他方に突設した複数のダボにより一体化される構成でもある。
更にまた、二分割して形成された管継手本体が、照明器具等の電源コードの通線孔となるように、合わせ面双方の縦方向全幅に半円溝を設け、合体したとき該半円溝が接合して貫通孔を形成する構造とすることも可能である。
Also, there are two divided pipe joint body formed by the, the plurality of dowel holes drilled in one of the further mating surfaces, even in the configuration are integrated by a plurality of dowels projecting from the other of the mating surfaces.
Furthermore, a semicircular groove is provided in the full width in the longitudinal direction of both mating surfaces so that the pipe joint body formed in two parts becomes a through hole for a power cord such as a lighting fixture. It is also possible to adopt a structure in which grooves are joined to form through holes.

本件発明の奥行パイプ嵌入部材は、一体成形とし、回動軸を正円柱とするとともに、管継手本体の回動支持部の軸受孔は正円とする必要がある。一体成形された回動軸を軸受孔に通すため、本発明は管継手本体を回動支持部の軸受孔の中心から縦方向に二分割して左右別個に製作し、半円ずつに分かれて形成された軸受孔に奥行パイプ嵌入部材の回動軸を挟み込んだ後、ダボ、係止ピン等を用いて合体、一体化する構成とする。   The depth pipe insertion member according to the present invention is integrally formed, the rotation shaft is a regular cylinder, and the bearing hole of the rotation support portion of the pipe joint body needs to be a perfect circle. In order to pass the integrally formed rotating shaft through the bearing hole, the present invention is manufactured by dividing the pipe joint main body into two parts in the vertical direction from the center of the bearing hole of the rotating support part, and separately manufacturing them in semicircles. After the rotation shaft of the depth pipe insertion member is sandwiched in the formed bearing hole, it is configured to be combined and integrated using a dowel, a locking pin, or the like.

本発明の折り畳みパイプ棚用管継手は、回動軸に螺子を使用することによる美感上の難点、組立上の煩雑さ、螺子の抜け落ちを排除すると共に、奥行パイプ嵌入部材を一体型とすることで回動軸部分の緩みによるパイプ棚の奥行方向への揺れを解消した。   The pipe joint for a folded pipe shelf according to the present invention eliminates the aesthetic difficulties, assembly difficulties, and screw drop-out caused by using a screw on the rotating shaft, and the depth pipe insertion member is integrated. This eliminates the shaking of the pipe shelf in the depth direction due to the looseness of the rotating shaft.

管継手本体は縦方向に二分割して形成され、回動支持部の軸受孔は合体して正円となり、回動軸は正円柱であるため、繰り返しの回動にも磨耗することなく長期の使用に耐える。（実際の棚の折畳みによる回動回数は一般機械類の回転軸の回転数と比較して極端に少ないものであるため正円と正円との摩擦であれば問題にならない。）また、一体成形では二次加工が必要となる照明器具等の電源コードの通線孔が容易に形成できるとともに、製品重量の削減ともなる。   The pipe joint body is divided into two parts in the vertical direction, the bearing holes of the pivot support part are united into a perfect circle, and the pivot shaft is a regular cylinder. Withstand use. (The actual number of rotations by folding the shelf is extremely small compared to the number of rotations of the rotating shaft of general machinery, so there is no problem if it is a friction between a perfect circle and a perfect circle.) In molding, a through hole for a power cord such as a luminaire that requires secondary processing can be easily formed, and the weight of the product can be reduced.
