（イ）従来より、脚立や梯子の支柱の下部の幅を横に広げ安定度を高める。また 支持棒を支柱の外側に取り付けることによって安定度を増させる。 （ロ）従来より、脚立や梯子の高所部分からロープ等で横倒れ方向にある堅固な ものに、例えば確立した樹木や杭などに張設、緊定し安定させる。 (B) Conventionally, the width of the lower part of the step of a stepladder or ladder is expanded laterally to improve stability. Stability is increased by attaching support rods to the outside of the columns. (B) Conventionally, it is secured by tightening it with a rope, etc. that is strong from the high part of the stepladder or ladder to the sideways direction, such as an established tree or pile, and tightens it.
【０００３】[0003]
（イ）脚立や梯子の支柱の下部の幅を横に広げても農園芸などの作業をする場所 は、足場の悪い所が多く安定しにくい。しかも土砂の地盤は使用しているうちに 地面が窪んで横倒れの原因となる。 （ロ）脚立や梯子をロープ等で張設、緊定させるには多くの労力と作業時間を要 する。しかも脚立や梯子を移動させる時は、安定を解除し、組みなおさなければ ならず作業のはかどらない欠点が見られた。 本考案はこれらの欠点を解決する為に考案されたもので簡単な操作と装置によっ て従来の欠点を除去せしめ、安定した脚立や梯子で農園芸の作業を計らんとする ものである。 (A) Even if the width of the lower part of the stepladder or ladder is widened horizontally, there are many places with poor scaffolding and it is difficult to stabilize the place where work such as agriculture and horticulture is performed. Moreover, the ground of the earth and sand will cause the ground to dent while it is in use, causing it to fall sideways. (B) It takes a lot of labor and work time to tension and tighten the stepladder and ladder with ropes. Moreover, when moving the stepladder or ladder, it was necessary to cancel the stability and reassemble it. The present invention has been devised to solve these drawbacks, and eliminates the conventional drawbacks with a simple operation and device, and aims at agricultural and horticultural work with a stable stepladder and ladder.

以下本考案の実施例について説明する。（イ）は把持部３の機構について。（ロ ）は掴持部１６の機構について。（ハ）は補助部２５の機構について分割して説 明する。 （イ）第１図、第２図に示すように、長尺柄１の把持部３にある操作レバー４を 開閉操作すると薄鋼帯Ｄを引いたり、緩めたりする。該操作によって連なってい る掴持部の可動部片を開閉させる作用を為す。 （ロ）掴持部１６の可動部片１７は、把持部３に設けた操作レバー４の開閉によ り薄鋼帯Ｄとワイヤー８とを接続して連結し作動せしめ回動させ掴持する動きと なる。 （ハ）なお長尺柄１の伸縮は第１図に示すように連結筒２を手で挿入したり引き 出したりすることで調節し、固設自在に設ける。 本考案は以上のような構造でこれを使用するときは、把持部３の操作レバー４に より掴持部１６の可動部片１７が回動する。すなわち農園芸の作業に脚立や梯子 を使用する場合、草木の幹や枝を可動部片１７が掴持し長尺柄１を脚立や梯子の 支柱に着脱可能に固説することにより脚立や梯子を安定ならしめる。 以下、構造の変化例を把持部３、掴持部１６、補助部２５に分割して実施例を説 明する。 「把持部３の第一実施例」 第２図、第３図に示すように、操作レバー４を開閉する際は、事前に逆転防止爪 Ａを掴持部１６の方向に指で押し、切り替えておく。つまり逆転防止爪車５を逆 転防止爪Ａがラチェットギヤーの働きにより適当な位置で回動を止めることがで きる状態にしておく。適当な位置とは操作レバー４を開閉操作することにより、 掴持部１６の可動部片１７が草木の幹や枝を掴持した時の状態である。なお逆転 防止爪Ａの回転軸に向かって、頭に球を付けた押しバネＰを設け、切り替え易く する。ケースＬ内の回転軸Ｎに回動自在に吊設されて連なった操作レバー４を手 で引くと、引きバネＥの作用で回転軸Ｏに枢着した逆転防止爪Ｂがラチェットギ ヤーの働きをする。すなわち回転軸Ｎに枢着１５した逆転防止爪車５を回動し、 薄鋼帯Ｄを巻き付けることとなり同時に掴持部１６の可動部片１７が回動し掴持 した状態となる。そして逆転防止爪Ａにストッパー６を掛ける。なお操作レバー ４から手を離すと引きバネＥの作用で元の位置に操作レバー４は戻り、ねじりコ イルバネＪの力で逆転防止爪車５から逆転防止爪Ｂは外れる。そして作業が終わ り枝や幹の掴持を解放させるにはストッパー６を外し、逆転防止爪Ａを指で引き 外せば逆転防止爪車５は回動自在となる。それによって薄鋼帯Ｄは緩み、連なっ ている掴持部１６の可動部片１７の、ねじりコイルバネＫの作用で可動部片１７ は開く。なお長尺柄１と連結筒２との伸縮については、連結筒２を手動で伸ばし たり縮めたりする。その際、薄鋼帯Ｃは回転軸Ｎに枢着１５した逆転防止爪車５ へ付着されたリール７に巻き付けられたり放されたりする。薄鋼帯Ｄがリール７ に巻き付けられる作用は、リール７と同軸の、つまり回転軸Ｎに巻着されたバネ 特性を持った薄鋼帯Ｃの作用による。なお引きバネＥは、ねじりコイルバネＪよ りバネの強度が強いものとする。又別途に、ねじりコイルバネＪの代用として操 作レバー４の一部と基部の一部に連結する引きバネを付けてもよい。また薄鋼帯 Ｃと操作レバー４や逆転防止車と付着されたリール７の並びは変えてもよい。な お薄鋼帯Ｄは定荷重コイルバネや曲げ変形、いわゆる座屈を起こさせ利用しても よい。また薄鋼帯Ｄの代わりにワイヤーや紐等でもよい。 「把持部３の第二実施例」 第４図、第５図に示すように、操作レバー４を開閉する際は事前に逆転防止爪Ａ を掴持部１６の方向に指で押し、切り替えておく。つまり逆転防止爪車５を逆転 防止爪Ａがラチェットギヤーの働きにより適当な位置で回動を止めることができ る状態にしておく。適当な位置とは操作レバーを開閉操作することにより、掴持 部１６の可動部片１７が草木の幹や枝を掴持した時の状態である。なお逆転防止 爪Ａの回転軸に向かって頭に球を付けた押しバネＰを設け、切り替え易くする。 ケースＬ内の回転軸Ｎに回動自在に吊設されて連なった操作レバー４と、該操作 レバー４の中央の一部に回転軸Ｏを設け、該軸Ｏに枢着された逆転防止爪Ｂを操 作レバー４と共に引くと、逆転防止爪Ｂがラチェットギヤーの働きをして、回転 軸Ｎに枢着１５した逆転防止爪車５を回動し、薄鋼帯Ｄを巻き付けることとなり 、同時に掴持部１６の可動部片１７が回動し掴持した状態となる。そして逆転防 止爪Ａにストッパー６を掛ける。なお操作レバー４から手を離すと、引きバネＦ の作用で元の位置に操作レバー４は戻り、該操作レバー４の一部分と、逆転防止 爪Ｂの一部分とに設けてある押しバネＱの力で、逆転防止爪車５から逆転防止爪 Ｂは外れる。そして作業が終わり枝や幹の掴持を解放させるにはストッパー６を 外し、逆転防止爪Ａを指で引き外せば逆転防止爪車５は回動自在となる。それに よって薄鋼帯Ｄは緩み、連なっている掴持部１６の可動部片１７の、ねじりコイ ルバネＫの作用で可動部片１７は開く。なお長尺柄１と連結筒２との伸縮につい ては、連結筒２を手動で伸ばしたり縮めたりする。その際、薄鋼帯Ｄは回転軸Ｎ に枢着１５した逆転防止爪車５へ付着されたリール７に巻き付けられたり放され たりする。薄鋼帯Ｄがリール７に巻き付けられる作用はリール７と同軸の、つま り回転軸Ｎに巻着されたバネ特性を持った薄鋼帯Ｃの作用による。なお引きバネ Ｆは、ねじりコイルバネＪよりバネの強度が強いものとする。又別途に、ねじり コイルバネＪの代用として操作レバー４の一部と基部の一部に連結する引きバネ を付けてもよい。また薄鋼帯Ｃと操作レバー４や逆転防止爪車５と付着されたリ ール７の並びは変えてもよい。なお薄鋼帯Ｄは定荷重コイルバネや曲げ変形、い わゆる座屈を起こさせ利用してもよい。また薄鋼帯Ｄの代わりにワイヤーや紐等 でもよい。 「把持部３の第三実施例」 第６図、第７図に示すように、逆転防止爪車３０の下方一部分に回転軸３２を設 け、回動自在に吊設された操作レバー２６の該回転軸３２に向かって頭に球を付

なお掴持部１６の方向へ操作レバー２６を押すと引掛け片９が薄鋼帯Ｒの穴から 外れ、押しバネＵの力で操作レバー２６の方向は切り替わり元の位置に保たれる 。そして薄鋼帯Ｗは巻着自在になり掴持部１６の可動部片１７は、ねじりコイル バネＫの作用で回動し可動部片１７が開く。なお薄鋼帯Ｗは回転軸２９に巻着し たバネ作用のあるものを使用し、例えば定荷重コイルバネを外側に反った状態の 渦巻形とし、その先端を内側に反った状態の定荷重コイルバネの先端とを重ねて 接続し渦巻形となす。そして薄鋼帯Ｖの先端部は把持部３から脱し掴持部１６の 可動部片１７を回動させる作用を為し連なる。なお頭に球を付けた押しバネＵと 同じ目的として、バネ座金１０と球１１を操作レバー２６の軸付近の一部分に孔 １２を堀り埋設し凸凹状の窪み１３に押圧、摺接して方向の切り替え作用をする 。 「把持部３の第四実施例」

(A) is about the mechanism of the grip 3. (B) is the mechanism of the grip portion 16. (C) separately describes the mechanism of the auxiliary unit 25. (A) As shown in FIGS. 1 and 2, when the operation lever 4 on the grip portion 3 of the long handle 1 is opened / closed, the thin steel strip D is pulled or loosened. This operation serves to open and close the movable part pieces of the gripping parts connected to each other. (B) The movable part piece 17 of the gripping part 16 connects and connects the thin steel strip D and the wire 8 by opening and closing the operation lever 4 provided on the gripping part 3 to operate and rotate to grip. It becomes a movement. (C) The expansion and contraction of the long handle 1 is adjusted by manually inserting or pulling out the connecting tube 2 as shown in FIG. When the present invention has the above-mentioned structure and is used, the movable part 17 of the holding part 16 is rotated by the operation lever 4 of the holding part 3. That is, when a stepladder or ladder is used for agricultural and horticultural work, the movable part piece 17 holds the trunk or branch of the tree and firmly attaches the long handle 1 to the prop of the stepladder or the ladder to attach or detach the stepladder or ladder. Stabilizes. Hereinafter, an example will be described by dividing a structural example into the grip portion 3, the grip portion 16, and the auxiliary portion 25. "First embodiment of the grip portion 3" As shown in FIGS. 2 and 3, when the operation lever 4 is opened and closed, the reverse rotation preventing claw A is pushed in the direction of the grip portion 16 with a finger in advance to switch. Keep it. That is, the reverse rotation preventing pawl 5 is set in a state in which the reverse rotation preventing pawl A can stop the rotation at an appropriate position by the action of the ratchet gear. The appropriate position is a state in which the movable portion 17 of the grasping portion 16 grasps the trunk or branch of the plant by opening / closing the operation lever 4. A push spring P having a ball on its head is provided toward the rotation axis of the reverse rotation preventing claw A to facilitate switching. When the operating lever 4 which is rotatably suspended and connected to the rotary shaft N in the case L is manually pulled, the reverse rotation preventing pawl B pivotally attached to the rotary shaft O by the action of the pulling spring E functions as a ratchet gear. do. That is, the reverse rotation preventing ratchet 5 pivotally attached to the rotating shaft N is rotated to wind the thin steel strip D, and at the same time, the movable portion 17 of the gripping portion 16 is rotated and gripped. Then, the stopper 6 is hooked on the reverse rotation preventing claw A. When the hand is released from the operation lever 4, the operation lever 4 returns to the original position by the action of the pulling spring E, and the reverse rotation preventing pawl B is disengaged from the reverse rotation preventing pawl wheel 5 by the force of the torsion coil spring J. When the work is completed and the grip of the branch or trunk is released, the stopper 6 is removed, and the reverse rotation preventing claw A is removed with a finger, whereby the reverse rotation preventing claw wheel 5 becomes rotatable. As a result, the thin steel strip D becomes loose, and the movable coil piece 17 is opened by the action of the torsion coil spring K of the movable coil piece 17 of the gripping portions 16 in series. Regarding expansion and contraction of the long handle 1 and the connecting tube 2, the connecting tube 2 is manually extended or contracted. At that time, the thin steel strip C is wound or released around the reel 7 attached to the reverse rotation preventing ratchet 5 pivotally attached to the rotation shaft N 15. The action of winding the thin steel strip D around the reel 7 is due to the action of the thin steel strip C coaxial with the reel 7, that is, wound around the rotation axis N and having a spring characteristic. The tension spring E is stronger than the torsion coil spring J. Further, as a substitute for the torsion coil spring J, a pulling spring may be attached to connect a part of the operating lever 4 and a part of the base. Further, the arrangement of the thin steel strip C and the operation lever 4 or the reel 7 attached to the reverse rotation preventing wheel may be changed.
