【発明の属する技術分野】
本発明は、特に伸縮ロッドの破損を防止すると共に、締着効果を高めることができる伸縮ロッド用クランプに関する。
【０００２】
【従来の技術】
伸縮ロッド用クランプは主に伸縮自在な洋服掛けのような、伸縮可能な内管と外管とを含む伸縮ロッドに用いられ、その内管は通常、外管の端部に設けられたクランプにより締着位置決めされる設計である。また、図６に示すように、その従来の伸縮ロッド用クランプの構造は主に環状のクランプ本体（６１）を有すると共に、その一側に、内部にナット（６２）が埋設された貫通孔（６１１）が設けられ、貫通孔（６１１）に、一端に回動部材（６３１）を有するボルト（６３）が外方へ延出するように螺合される。
そのクランプを例えば洋服掛け用伸縮ロッドに使用する場合には、内管（５２）が挿設された外管（５１）の端部に環状のクランプ本体（６１）を固設すると共に、内管（５２）を希望の長さまで伸長させ、その後、回動部材（６３１）を回動させて、ボルト（６３）の端部で外管（５２）を適当に押圧することにより、内管（５２）を締着、位置決めする。
【０００３】
【発明が解決しようとする課題】
しかし、上記従来のクランプにおける内管への締着力はクランプ本体に螺設されるボルトと環状のクランプ本体との挟持力によるものであり、内管に加わる負荷が大きいほど、内管への挟持力を強くする必要があるので、内管の表面が破損しやすく、管壁の薄い内管の場合には、内管が更に変形して外管内においてスムーズに伸縮できなくなるという問題があった。
【０００４】
【課題を解決するための手段】
本発明は、
伸縮ロッド（４０）における外管（４１）の端部に設けられ、外管（４１）と、外管（４１）内に伸縮可能に設けられる内管（４２）とを締結するクランプ（１）であり、
上下方向に外管（４１）と対応する貫通穴（１１）が形成されると共に、側面に、外方へ延出し且つ貫通穴（１１）と連通する組付穴（１２）が貫通穴（１１）の径方向に形成されるクランプ本体（１０）と、
内管（４２）が嵌通すると共に、クランプ本体（１０）内において径方向に移動可能であり、側面に、組付穴（１２）に収容され、且つ内部に該組付穴（１２）の軸方向にネジ穴（２２）が形成される螺合部（２１）が設けられるスリーブ（２０）と、
ネジ穴（２２）と対応し、端部に外径が組付穴（１２）よりも大きい回動部材（３２）が設けられるボルト（３１）を有する螺合部材（３０）と、からなり、内管（４２）が嵌通したスリーブ（２０）に螺合部材（３０）が螺入されると共に、内管（４２）は、クランプ本体（１０）に固設された外管（４１）に押圧されることにより、クランプ本体（１０）に締着されることを特徴とする伸縮ロッド用クランプ、を提供する。
【０００５】
【作用】
本発明は上記の課題を解決するものであり、従来の内管はボルトと環状のクランプ本体との挟持力により締着、位置決めされるのに対し、本発明は内管が、スリーブとクランプ本体との挟持力で締着、位置決めされることにより、挟持面積が大きくなるので、伸縮ロッドにおける内管への締着効果を向上させることができると共に、内管が変形しにくくなり、結果的に破損を防止することができる。
【０００６】
以下、添付図面を参照して本発明の好適な実施の形態を詳細に説明する。

【０００８】
図１乃至図３に示すように、本発明に係る、内管（４２）と外管（４１）からなる伸縮ロッド用クランプ（１）はクランプ本体（１０）とスリーブ（２０）と螺合部材（３０）とを含み、クランプ本体（１０）は上継手（１０１）と下継手（１０２）を、高周波や接着剤又は締結部材による接合方式により一体に構成されると共に、上下方向に外管（４１）と対応する貫通穴（１１）が形成され、側面に、外方へ延出し且つ貫通穴（１１）と連通する組付穴（１２）が貫通穴（１１）の径方向に形成される。
スリーブ（２０）は、内管（４２）が嵌通し、クランプ本体（１０）内において径方向に移動可能であると共に、側面に、組付穴（１２）に収容され、且つ内部に組付穴（１２）の軸方向にネジ穴（２２）が形成される螺合部（２１）が設けられる。又、前記ネジ穴（２２）の代わりに、螺合部（２１）の内部にネジ穴（２２）を有するナットを設けても良い。
螺合部材（３０）は、ネジ穴（２２）と対応するボルト（３１）を有し、そのボルト（３１）の端部に外径が組付穴（１２）よりも大きい回動部材（３２）が設けられる。
【０００９】
このようなクランプ（１）を伸縮ロッド（４０）に組合わせる場合には、図２及び図３に示すように、外管（４１）の端部にクランプ本体（１１）を固設すると共に、クランプ本体（１１）の上端から内管（４２）をスリーブ（２０）に挿通するように挿入して、外管（４１）内に組合わせる。
そして、内管（４２）を希望の長さに設定した後、図４及び図５に示すように、回動部材（３２）を回動させると共に、螺合部材（３０）をスリーブ（２０）に螺入させることにより、スリーブ（２０）を移動させ、外管（４１）が適当に押圧されるまで内管（４２）をクランプ本体（１１）内において横移動させる。この時、内管（４２）は、クランプ本体（１０）と一体になった外管（４１）とスリーブ（２０）との挟持力によりクランプ本体（１０）に締着、位置決めされる。
【００１０】
【発明の効果】
本発明は上記の構成を有するので、伸縮ロッドを破損させずに内管への締着効果を高めることができる。

[0002]
[Prior art]
Telescopic rod clamps are mainly used for telescopic rods, including telescopic inner and outer tubes, such as telescopic clothes, and the inner tube is usually clamped at the end of the outer tube. It is designed to be fastened and positioned. Further, as shown in FIG. 6, the conventional telescopic rod clamp structure mainly has an annular clamp body (61) and a through hole (with a nut (62) embedded therein on one side thereof. 611), and a bolt (63) having a rotating member (631) at one end is screwed into the through hole (611) so as to extend outward.
When the clamp is used, for example, as a clothes-hanging telescopic rod, an annular clamp body (61) is fixed to the end of the outer tube (51) in which the inner tube (52) is inserted, and the inner tube (52) is extended to a desired length, and then the rotating member (631) is rotated, and the outer tube (52) is appropriately pressed by the end of the bolt (63), thereby causing the inner tube (52 ) And position.
[0003]
[Problems to be solved by the invention]
However, the clamping force to the inner tube in the conventional clamp is due to the clamping force between the bolt screwed to the clamp body and the annular clamp body. The larger the load applied to the inner tube, the more the clamping force to the inner tube is. Since it is necessary to increase the force, the surface of the inner tube is easily damaged, and in the case of the inner tube having a thin tube wall, there is a problem that the inner tube is further deformed and cannot be smoothly expanded and contracted in the outer tube.
[0004]
[Means for Solving the Problems]
The present invention

Provided is a telescopic rod clamp that is clamped to a clamp body (10) by being pressed.
[0005]
[Action]
The present invention solves the above-mentioned problems, while the conventional inner tube is fastened and positioned by the clamping force between the bolt and the annular clamp body, whereas the present invention is composed of the sleeve and the clamp body. Since the clamping area is increased by clamping and positioning with the clamping force, the effect of fastening the telescopic rod to the inner tube can be improved and the inner tube is less likely to be deformed. Breakage can be prevented.
