本考案は、リーチフオークリフトトラツクのリ
ーチレツグに関するものである。[Detailed Description of the Invention] The present invention relates to a reach leg for a reach forklift truck.
リーチフオークリフトトラツクは、第１図に示
すように、フレームａに一対のリーチレツグｂを
設け、マスト部ｃを一対のリーチレツグｂに沿つ
て摺動自在としたものである。 As shown in FIG. 1, the reach fork lift truck has a frame a with a pair of reach legs b, and a mast part c that is slidable along the pair of reach legs b.
つまり、リーチレツグｂはマスト部ｃのローラ
ｄのガイド部材である。ｅはバツテリ。 In other words, reach leg b is a guide member for roller d of mast section c. e is boring.
前記リーチレツグｂは第２図〜第５図に示すよ

イドするレールｆと、レールｆの上部に設けたカ
バｇとより成り、カバｇはレールｆに設けた車輪
（タイヤ）ｈをカバすると共に、リーチレツグ全
体の剛性（特にねじれ防止）を向上させるための
ものである。 As shown in FIGS. 2 to 5, the reach leg b consists of a U-shaped rail f that guides the roller d in the front-rear direction, and a cover g provided on the top of the rail f. This is intended to cover the wheels (tires) h provided at f and to improve the rigidity (particularly to prevent twisting) of the entire reach leg.
しかし、この構造であると第６図、第７図に示
すように、リーチレツグｂには、マスト部ｃの一

上向の力W3、前方のローラｄにより下向の力W2
が作用すると共に、車輪ｈが路面から受ける力
W1とが作用し、前記上下向の力W3，W2と力W1
との作用点がL1という距離だけ離れているので、
リーチレツグｂには大きな曲げモーメントが作用
することになり、ねじり防止のためにリーチレツ
グｂを構造的に剛性大なるものとせねばならずコ
スト高となつてしまう。 However, with this structure, as shown in FIGS. 6 and 7, the reach leg b is subjected to an upward force W 3 and a forward force caused by the rear roller d' of the pair of rollers d and d' of the mast part c. The downward force W 2 caused by the roller d of
acts, and the force that the wheel h receives from the road surface
W 1 acts on the above-mentioned vertical forces W 3 , W 2 and force W 1
Since the point of action with is separated by a distance of L 1 ,
A large bending moment acts on the reach leg b, and in order to prevent twisting, the reach leg b must be made structurally rigid, resulting in high cost.
本考案は上記の事情に鑑みなされたものであ
り、その目的は、リーチレツグに作用するマスト
部のローラよりの力と車輪よりの力との作用点を
一致させて曲げモーメントが作用しないようにし
たリーチフオークリフトトラツクのリーチレツグ
を提供することである。 The present invention was developed in view of the above circumstances, and its purpose is to align the points of application of the force from the rollers of the mast section and the force from the wheels acting on the reach leg so that no bending moment is applied. To provide a reach leg for a reach forklift truck.
以下第８図以降を参照して本考案の実施例を説
明する。 Embodiments of the present invention will be described below with reference to FIG. 8 and subsequent figures.
第８図は全体正面図であり、運転席を備えた車
体１には左右一対のリーチレツグ２，２が前方に
向けて固設され、該一対のリーチレツグ２，２に
沿つてマスト部３が前後摺動自在に設けてある。 FIG. 8 is an overall front view, and a pair of right and left reach legs 2, 2 are fixedly fixed to the front of the vehicle body 1 equipped with a driver's seat, and a mast portion 3 is mounted front and rear along the pair of reach legs 2, 2. It is slidably provided.
該マスト部３はフオーク爪４を昇降自在に支承
したマスト５と、マスト５に後方に向けて一体的
に設けた横材６とを備え、マスト５には前方ロー
ラ７とマスト逆転防止用の止めプレート８とが設
けられ、横材６には後方ローラ９が設けてある。 The mast section 3 includes a mast 5 that supports a fork claw 4 so as to be able to move up and down, and a cross member 6 that is integrally provided to the mast 5 toward the rear. A stop plate 8 is provided, and the cross member 6 is provided with a rear roller 9.
前記リーチレツグ２は、上横壁１０と縦壁１１
と下横壁１２とによつて内向コ字状となり、上横
壁１０の上面１０ａに前方ローラ７が摺接して、
その摺動ガイド面となり、下面１０ｂに後方ロー
ラ９が摺接して、その摺動ガイド面となつている
と共に、下面１０ｂに止めプレート８が摺動自在
に接していると共に、下横壁１２の前端部分は切
除１２ａされ、かつ縦壁１１の内側面１１ａの前
端部分には支軸１３が設けてあり、この支軸１３
に車輪１４が回転自在に支承されて、車輪１４と
前方ローラ７、後方ローラ９は左右方向に同一位
置となつている。 The reach leg 2 has an upper horizontal wall 10 and a vertical wall 11.
and the lower horizontal wall 12 form an inward U-shape, and the front roller 7 is in sliding contact with the upper surface 10a of the upper horizontal wall 10.
The rear roller 9 is in sliding contact with the lower surface 10b, and the stop plate 8 is in slidable contact with the lower surface 10b, and the front end of the lower horizontal wall 12 The portion is cut out 12a, and a support shaft 13 is provided at the front end portion of the inner surface 11a of the vertical wall 11.
A wheel 14 is rotatably supported, and the wheel 14, the front roller 7, and the rear roller 9 are at the same position in the left-right direction.
つまり、リーチレツグ２は第１３図ａ〜ｄに示
すように、コ字状材２′の下横壁１２の前端側を
切欠１２ａし、その部分と対向した縦壁内側面１
１ａに支軸１３を溶接固定し、この支軸１３に車
輪１４を回転自在に支承して製作する。 That is, as shown in FIGS. 13a to 13d, the reach leg 2 has a notch 12a in the front end side of the lower horizontal wall 12 of the U-shaped member 2', and an inner side surface 1 of the vertical wall opposite to the notch 12a.
A support shaft 13 is welded and fixed to 1a, and a wheel 14 is rotatably supported on this support shaft 13.
しかして、マスト部３は、前方ローラ７、後方
ローラ９がリーチレツグ２の上横壁上面１０ａ、
下面１０ｂに沿つて摺動することで前後方向に移
動するので、前方ローラ７は車輪１４と干渉する
ことがない。 Thus, in the mast part 3, the front roller 7 and the rear roller 9 are connected to the upper surface 10a of the upper horizontal wall of the reach leg 2,
Since the front roller 7 moves in the front-back direction by sliding along the lower surface 10b, the front roller 7 does not interfere with the wheels 14.
また、第１４図に示すように、前方ローラ７は
上横壁１０の上面１０ａにW2の力で押しつけら
れ、後方ローラ９は上横壁１０の下面１０ｂに
W3の力で押し上げられ、車輪１４はW1の力で路
面に押しつけられるが、前方ローラ７、後方ロー
ラ９、車輪１４は左右方向に同一位置となつて垂
直方向に並設した状態であるから、前記各力W1，
W2，W3の作用点は略同一線上となり、リーチレ
ツグ２には曲げモーメントがほとんど作用しな
い。 Further, as shown in FIG. 14, the front roller 7 is pressed against the upper surface 10a of the upper horizontal wall 10 with a force of W2 , and the rear roller 9 is pressed against the lower surface 10b of the upper horizontal wall 10.
The wheel 14 is pushed up by the force W 3 and pressed against the road surface by the force W 1 , but the front roller 7, the rear roller 9, and the wheel 14 are in the same position in the left and right direction and are arranged vertically side by side. From, each of the above forces W 1 ,
The points of action of W 2 and W 3 are approximately on the same line, and almost no bending moment acts on the reach leg 2.
したがつて、リーチレツグ２の剛性を強くして
ねじりを防止する必要がないから、コストを安く
できる。 Therefore, there is no need to increase the rigidity of the reach legs 2 to prevent twisting, so costs can be reduced.
本考案は以上の様になり、上横壁１０の上面１
０ａ、下面１０ｂに作用する下向の力W2、上向
の力W3、車輪１４に作用する力W1の作用線が略
直線上となり、リーチレツグ２に大きな曲げモー
メントが作用しないから、剛性を大としてねじり
を防止する必要がない。 The present invention is as described above, and the upper surface 1 of the upper horizontal wall 10
0a, the lines of action of the downward force W 2 acting on the lower surface 10b, the upward force W 3 , and the force W 1 acting on the wheel 14 are approximately straight lines, and no large bending moment acts on the reach leg 2, so the rigidity There is no need to make it large to prevent twisting.
したがつて、リーチレツグ２を構造簡単として
コスト安に製作できる。 Therefore, the reach leg 2 has a simple structure and can be manufactured at low cost.
