【発明の詳細な説明】
本発明はパイプ、棒等を簡単かつ確実に接続す
るための継手に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coupling for connecting pipes, rods, etc. simply and reliably.
現在、例えばマンシヨン等のベランダの手すり
や建設用足場材などのパイプ状部材同士の接続に
は主としてスリーブ型継手又は溶接手段が用いら

切り作業を伴う。これに反し後者の溶接手段は、
作業さえ適当に行われるならば外観的にも強度的
にも概ね満足すべき結果が得られるが、逆にその
取り外しは事実上不可能である。 Currently, sleeve-type joints or welding means are mainly used to connect pipe-like members such as handrails on balconies of condominiums and scaffolding materials for construction. The former sleeve-type joint is the easiest to use, but since the outside diameter of the joint is inevitably larger than the outside diameter of the pipe-like member to be connected, it is inferior in appearance, and the length and thickness of the joint are Desired strength cannot be obtained unless the thickness is made sufficiently large. Moreover, when attempting to connect the two with screws, a troublesome thread cutting operation is involved. On the other hand, the latter welding method is
If the work is done properly, generally satisfactory results can be obtained in terms of appearance and strength, but on the other hand, it is virtually impossible to remove them.
今日、各地において高層マンシヨンの建設が進
められ、必然的に安全用手すりに対する需要が増
加しているが、荷物用大型エレベーターは殆んど
設備されていない。従つて、ピアノ、大型家具等
の搬入や搬出には、クレーンカーを用いベランダ
側から搬入しなければならない場合が少なくない
が、この場合、手すりが邪魔になることが非常に
多く、さりとて殆んど溶接により設置されている
手すりをその都度切断して取り外し、事後復元す
るには著しい手数と費用がかかる。 Nowadays, construction of high-rise condominiums is progressing in various places, and the demand for safety handrails is inevitably increasing, but large elevators for luggage are hardly equipped. Therefore, when bringing in or removing pianos, large furniture, etc., it is often necessary to use a crane car to bring them in from the balcony side, but in this case, the handrails are very often in the way, and it is almost impossible to carry them in. It takes considerable effort and expense to cut and remove handrails that have been installed by welding each time, and then restore them after the fact.
以上、仮にマンシヨンのベランダについて見た
ものであるが、より多角的に見れば、例えば歩道
用の安全柵、ポール、フエンス、建設用の足場、
仮設建築物もしくは構築物、体育館等のトラスな
ど、パイプ材や棒状材の対面を簡単、かつ確実に
接続したい場合は極めて多い。本発明はこの要望
に応えようとするものである。 The above is a hypothetical example of an apartment balcony, but if you look at it from a more diverse perspective, for example, safety fences for sidewalks, poles, fences, construction scaffolding,
There are many cases where it is desired to simply and reliably connect the opposing faces of pipes or rods, such as in temporary buildings or structures, trusses for gymnasiums, etc. The present invention seeks to meet this need.
本発明継手の最大の特徴は、被接続パイプ材や

かも面倒な工作を必要する。その上、接続部分の
外径はその他の部分に比しずつと大きくなる。本
発明は以上の公知継手における欠点を抜本的に解
消させようとするものである。 The most important feature of the joint of the present invention is that the pipe material or rod-shaped material to be connected can be connected with their opposing end surfaces in contact with each other.
Moreover, the connection can be made reliably without having to fit a sleeve or the like in advance (that is, without protruding from the pipe to be connected). Anyone working in this field can easily imagine how useful this feature is in practice. Incidentally, a cap nut, which is frequently used for connecting pipes, has a function similar to the joint of the present invention to some extent, but it is far inferior in strength and requires troublesome machining. Moreover, the outer diameter of the connecting portion is gradually larger than that of the other portions. The present invention is intended to fundamentally eliminate the drawbacks of the above-mentioned known joints.

It is fitted into the inner peripheral surface of the sleeve so as to be slidable along the axial direction of the sleeve (see also FIG. 2). One end of this screw member 5 is screwed into a screw hole 7 drilled in the cover plate 8 of the tubular casing, while the other end advances and retreats into the through hole 12 bored in the rotating ring 11 of the tubular sleeve 4. It is inserted freely.

The stepped portions 6 of the tubular casings 3 of the connecting members 1 to 3 of the present joint shown in FIG. 1 are tightly fitted.

な結合効果が得られる。 On the other hand, the stepped portions 16 of the tubular bodies 13 of the connected members 2 to 2 of the joint of this embodiment are tightly fitted into the other frame ends F2 of the upper and lower pipe frames F, F'. Then,
As shown in FIG. 4, the front surface of the rotating ring 11 of the former and the front surface of the front closing plate 14 of the latter are brought into contact so that the respective axes of the connecting member 1 and the connected members 2 are coaxially aligned. Then, when the rotary wheel 11 is rotated toward the front in the figure, the screw member 5 rotates and moves forward, and its front end is screwed into the screw hole 15 of the connected member 2. As the screw member 5 advances, the front surfaces of both members 1 and 2 are firmly and closely connected to each other. Furthermore, if an auxiliary tightening rod (indicated by a dotted line) is inserted into a concave hole 11a bored on the circumferential surface of the rotary wheel 11 and the rotary wheel 11 is rotated, a stronger coupling effect can be obtained. It will be done.

になつている。 FIG. 5 is a sectional view of a joint according to another embodiment of the invention. This example joint is different from the previous example except that a concentric annular groove 9 and a concentric annular rib 10 are formed at positions adjacent to the inside of the cover plate 8 of the tubular portion 3 and at one end of the tubular sleeve 4. It is constructed similarly to the former, and provides the same strong bonding effect, but is easier to manufacture than the former. In this example, a set screw 17 is attached to the casing 3 to prevent the rotating wheel 11 from moving inadvertently.

トがそのまま利用できるため、工作の手数を大幅
に減らすことができる。 The shape of the inner surface of the sleeve 4 in the joints of the previous examples does not necessarily have to be a regular polygon. In short, it is sufficient if the shape is sufficient to engage with the enlarged portion 5b of the screw member 5 and cause the screw to move forward and backward while rotating. For example, even if a keyway is cut along the axial direction on the inner surface of the sleeve 4 and a rib corresponding to the keyway protrudes from the middle part of the sleeve 5, the result will be exactly the same. However, if it is formed into a regular hexagonal shape as in the previous example, a commercially available hexagonal nut can be used as is as the enlarged portion 5b of the screw member, and the number of machining steps can be greatly reduced.

This not only increases the strength, but also allows the hollow portion to be used as a passage for electric wires, etc.

It has great utility as a joint material for architectural scaffolding, temporary structures, etc.
