Description
【０００１】[0001]
本考案は、例えば、幼児用ジャングルジムの如く、多数のパイプや丸棒を継手 により接続するためのパイプの継手構造に関するものである。 The present invention relates to a pipe joint structure for connecting a large number of pipes or round bars with a joint, such as a jungle gym for infants.
【０００２】[0002]
この種の継手構造の一例として、実開昭６３−１６９１５８号公報に記載され た幼児用ジャングルジムに関する考案がある。この考案は、パイプを挿入しうる 筒体と、その外周から軸方向に対して直角に突設した断面十字状の突出部とによ りジョイトンを構成し、筒体にパイプを挿入すると共に、突出部にパイプを嵌合 して接続し、ジャングルジムを構築するようにしたものである（従来技術１）。 As an example of this type of joint structure, there is a device for a jungle gym for infants described in Japanese Utility Model Laid-Open No. Sho 63-169158. In this invention, a joyton is composed of a tubular body into which a pipe can be inserted and a projecting portion having a cross-shaped cross section that projects from the outer periphery at a right angle to the axial direction, and the pipe is inserted into the tubular body. A jungle gym is constructed by fitting and connecting a pipe to the protrusion (prior art 1).
【０００３】 また、実公平５−１４００４号公報には、上部に支持部材を有し、長さ方向に 外周を３等分するように切欠部が設けられ、下端部が鍔状に形成されて切欠部間 の鍔状外周面がそれぞれ周方向のテーパー状面部に形成された筒状物と、内周面 に３個の突出部が設けられて筒状物の下端部に回転可能に装着された固定部材と からなり、固定部材を回転させて突出部によりテーパー状面部を押圧し、筒状物 内に挿入された管等を押圧固定するようにした部材固定具に関する考案が記載さ れている（従来技術２）。In Japanese Utility Model Publication No. 5-14004, a support member is provided on the upper portion, a notch is provided so as to divide the outer circumference into three equal parts in the lengthwise direction, and the lower end is formed in a brim shape. A tubular object having a flange-shaped outer peripheral surface between the notches formed on the tapered surface portion in the circumferential direction, and three protrusions provided on the inner peripheral surface are rotatably mounted on the lower end portion of the cylindrical object. The invention relates to a member fixing device in which a fixing member is rotated, and a tapered surface is pressed by a protruding portion to press and fix a pipe or the like inserted in a cylindrical object. (Prior art 2).
【０００４】[0004]
従来技術１の考案は、パイプの内径は必ずしも一定ではないため、ジョイント の突出部に対してパイプの内径がゆるい場合は、構築されたジャングルジムが分 解するおそれがあり、危険である。また、パイプの内径がきつい場合は、木槌等 でパイプを叩いて圧入しなければならないので、組立作業が面倒である。 また、幼児の成長に伴ってパイプを長くする等の組替作業が必要であるが、こ の際にも新しいパイプの組替えの際上記のような問題があり、特に、パイプをジ ョイントの突出部に圧入した場合は、その取外し作業がきわめて面倒である。 さらに、筒体に挿入された縦方向のパイプは、筒体の内周面に設けられたリブ によって支承されているだけなので、ときとして、パイプがリブを破壊してジョ イントから突出し、あるいはリブがパイプを破壊するおそれがあり、ジャングル ジムが分解するだけでなく、危険である。 In the device of the prior art 1, since the inner diameter of the pipe is not always constant, if the inner diameter of the pipe is loose with respect to the protruding portion of the joint, the constructed jungle gym may be broken, which is dangerous. Also, if the inner diameter of the pipe is too tight, it is necessary to hit the pipe with a mallet or the like to press it in, which makes the assembly work troublesome. In addition, it is necessary to change the pipe length as the infant grows up.However, there is a problem as described above when changing a new pipe. If it is press-fitted into the part, its removal work is extremely troublesome. Furthermore, since the vertical pipe inserted into the cylinder is only supported by the ribs provided on the inner peripheral surface of the cylinder, the pipe sometimes breaks the rib and protrudes from the joint, or Could break the pipe, not only disassembling the jungle gym but also dangerous.
【０００５】 従来技術２の考案は、固定部材を回転させるだけで管等を着脱できるためきわ めて便利であり、その上管等の外径に若干のバラツキがあっても、固定部材の締 めしろを調節するだけで確実に管等を接続することができる等、種々特長を有す る。 しかしながら、長期の使用などにより固定部材がゆるむことがあると、管等が 脱落することがあり、やはり危険である。The device of the prior art 2 is extremely convenient because the pipe and the like can be attached and detached only by rotating the fixing member, and even if there is some variation in the outer diameter of the upper pipe or the like, the fixing member is tightened. It has various features such as the ability to connect pipes securely by adjusting the margin. However, if the fixing member may loosen due to long-term use, the pipe may fall off, which is also dangerous.
【０００６】 本考案は、上記の課題を解決するためになされたもので、パイプの着脱及び固 定が容易かつ確実で、その上固定リングがゆるむおそれのないパイプの継手構造 を得ることを目的としたものである。The present invention has been made to solve the above problems, and an object of the present invention is to obtain a pipe joint structure in which the pipe can be easily attached and detached and fixed, and the fixing ring does not loosen. It is what
