（実施例）以下本考案のブレス装置を図面に示す実施例に
従い説明する。(Embodiments) The breath device of the present invention will be described below according to embodiments shown in the drawings.

第１図は本考案のブレス装置を示し、該ブレス
装置は角パイプの外筒２を有する。 FIG. 1 shows a brace device according to the present invention, which has an outer cylinder 2 made of a square pipe.

該外筒２内には角パイプの内筒７が摺動可能に
収納される。 Inside the outer cylinder 2, an inner cylinder 7 made of a square pipe is slidably housed.

次に外筒２には複数の孔２ａが及び内筒７には
複数の孔７ａが各々設けられる。 Next, the outer cylinder 2 is provided with a plurality of holes 2a, and the inner cylinder 7 is provided with a plurality of holes 7a.

一方外筒２の一端には雌ねじ３が固定され、該
雌ねじ３には取付端５を有するねじ体４がねじ結
合される。 On the other hand, a female screw 3 is fixed to one end of the outer cylinder 2, and a screw body 4 having a mounting end 5 is screwed to the female screw 3.

又内筒７の一端には雌ねじ８が固定され、該雌
ねじ８には取付端１０を有するねじ体９がねじ結
合される。 Further, a female screw 8 is fixed to one end of the inner cylinder 7, and a screw body 9 having a mounting end 10 is screwed to the female screw 8.

次に前記外筒２の孔２ａと内筒７の孔７ａには
第２図に示す様にピン１２が挿入可能に設けられ
る。 Next, a pin 12 is inserted into the hole 2a of the outer cylinder 2 and the hole 7a of the inner cylinder 7, as shown in FIG.

又内筒７は抜け止め板１１により外筒２からの
抜け落ちが防止される。 Further, the inner cylinder 7 is prevented from falling off from the outer cylinder 2 by a retaining plate 11.

以上の実施例に示した本考案のブレス装置の作
用は次の通り。 The operation of the breath device of the present invention shown in the above embodiments is as follows.

すなわち長さを調節する際には内筒７を外筒２
内で摺動させ（第１図は伸ばした状態及び第３図
は縮めた状態）所定の位置でピン１２を第２図に
示す様に外筒２の孔２ａと内筒７の孔７ａを貫通
して挿入する。 In other words, when adjusting the length, the inner tube 7 is replaced by the outer tube 2.
(Fig. 1 is the extended state and Fig. 3 is the retracted state) and the pin 12 is inserted into the hole 2a of the outer cylinder 2 and the hole 7a of the inner cylinder 7 as shown in Fig. 2. Penetrate and insert.

次にねじ体４，９を外筒２及び内筒７に対して
回転させてその突出長さを調節する。 Next, the screw bodies 4 and 9 are rotated relative to the outer cylinder 2 and the inner cylinder 7 to adjust their protruding length.

この際外筒２と内筒７は角パイプであるため相
互に回転することはない。 At this time, since the outer cylinder 2 and the inner cylinder 7 are square pipes, they do not rotate relative to each other.

以上の結果ブレス装置の長さは調節されたこと
になる。 As a result of the above, the length of the brace device has been adjusted.

本考案のブレス装置は以上の実施例以外に次の
構成にしてもよい。 In addition to the above-described embodiments, the breath device of the present invention may have the following configuration.

すなわち第４図に示す様に外筒２に回転ハンド
ル１４を取り付けておき工具がなくても外筒２及
び内筒７をねじ体４，９に対して回転可能にして
もよい。 That is, as shown in FIG. 4, a rotary handle 14 may be attached to the outer cylinder 2 so that the outer cylinder 2 and the inner cylinder 7 can be rotated relative to the screw bodies 4 and 9 without a tool.

次に第５図に示す様に内筒７を比較的長くして
外筒２から内筒７を伸び出し可能に構成してもよ
い。 Next, as shown in FIG. 5, the inner cylinder 7 may be made relatively long so that the inner cylinder 7 can extend from the outer cylinder 2.

この様に内筒７を長くすればそれにねじ結合さ
れるねじ体９は短く出来、その結果装置としての
強度が向上することになる。 If the inner cylinder 7 is lengthened in this manner, the screw body 9 screwed thereto can be shortened, and as a result, the strength of the device is improved.

（考案の効果）本考案のブレス装置の実施例は以上の通りであ
りその効果を次に列記する。(Effects of the invention) The embodiments of the breath device of the invention are as described above, and the effects thereof are listed below.

(1) 本考案のブレス装置は実用新案登録請求の範
囲に記載した構成であり、特に外筒に対して内
筒を摺動させるため長さ調節の範囲が極めて大
きい。(1) The brace device of the present invention has the configuration described in the claims of the utility model registration, and in particular, the range of length adjustment is extremely wide because the inner cylinder slides with respect to the outer cylinder.
