本考案はフォークリフトトラック等に装設されている昇
降装置、換言すればマスト装置の改良構造に関する。[Detailed Description of the Invention] The present invention relates to an improved structure of a lifting device installed in a forklift truck or the like, in other words, a mast device.
昇降装置は通常、車体側に固定された外枠と、これに対
して上下動する内枠、並びに該内枠に沿動するリフトブ
ラケット等から構成され、これらの間には相対移動を円
滑ならしめる為に前後方向の荷重を受推するエンドロー
ラが配されている。Lifting devices usually consist of an outer frame fixed to the vehicle body, an inner frame that moves up and down relative to the outer frame, and a lift bracket that moves along the inner frame. For tightening, end rollers are provided that receive loads in the front and rear directions.
而して従来に於ては前記各エンドローラの直径が同一と
なる様に第８図に明示する如く外枠２並びに内枠３の夫
々対向するフランジ部間、即ちローラ転動面幅Ａ、 Ａ
は同長にしてあった。Conventionally, in order to make the diameters of the respective end rollers the same, as shown in FIG. A
were of the same length.
然しながら例えば同図に示すＣＪ型マストに於ては内枠
３の強度が外枠２より両者の断面係数に依って高くなっ
ており、今まではこの内枠３の経済面を犠牲にして単一
化を図っていた。However, for example, in the CJ type mast shown in the figure, the strength of the inner frame 3 is higher than that of the outer frame 2 due to the section modulus of both, and up until now, the strength of the inner frame 3 has been higher at the expense of the economic aspect of the inner frame 3. They were trying to unify.
即ち、強度面並びに経済面から云えば第７図に示す如く
内枠３を小さくすることが出来るのである。That is, from the viewpoint of strength and economy, the inner frame 3 can be made smaller as shown in FIG.
併し、この様にすれば内枠３のローラ転動面幅Ｂが外枠
２のそれＡより狭幅となるので使用するエンドローラは
一般的思考からは異径のものとせねばならず、部品の共
通化並びにサービス性の観点からは問題が多い難点があ
る。However, if this is done, the roller rolling surface width B of the inner frame 3 will be narrower than that of the outer frame 2, so the end rollers used must be of different diameters from a general perspective. There are many problems in terms of common parts and serviceability.
本考案は上述問題点に鑑みこれを解消する為に創案され
た°もので、その主たる目的は内枠、外枠共に強度面を
尊重した寸法にし、且つこれらの間に配されるエンドロ
ーラの直径を共通化した昇降装置を提供するにある。This invention was devised in order to solve the above-mentioned problems, and its main purpose is to make the inner frame and outer frame dimensions that respect strength, and to make the end rollers arranged between them. An object of the present invention is to provide a lifting device having a common diameter.
本考案の他の目的はこの種昇降装置の構造上の特性、即
ち各粋の対向するフランジ部の一方しかエンドローラが
通常当合しないことに着眼して、内枠のローラ転動面幅
を基準として各エンドローラの直径を定めた昇降装置を
提供するにある。Another purpose of the present invention is to reduce the width of the roller rolling surface of the inner frame by focusing on the structural characteristics of this type of lifting device, namely the fact that the end rollers normally come into contact with only one of the opposing flanges of each shaft. To provide a lifting device in which the diameter of each end roller is determined as a reference.
本考案の更に他の目的は内枠に軸設された外枠の後側フ
ランジ部内面を転動するエンドローラの近傍に、外枠の
前側フランジ部内面に当合する摺動片を内枠に設け、外
枠と内枠とのがたつきを防止した昇降装置を提供するに
ある。Still another object of the present invention is to install a sliding piece that abuts against the inner surface of the front flange of the outer frame in the vicinity of an end roller that rolls on the inner surface of the rear flange of the outer frame that is pivoted on the inner frame. To provide an elevating device which is installed in a frame and prevents rattling between an outer frame and an inner frame.
以下本考案の実施例を示す図面に基づきその詳細を説明

It's a shame.
他方、内枠３は断面路Ｊ型の左右の枠材１３゜１３と連
結材１４から戊り同様に枠材１３．１３の溝部は対向し
ている。On the other hand, the inner frame 3 has a J-shaped cross section, and is cut out from the left and right frame members 13.13 and the connecting member 14, and the grooves of the frame members 13.13 are similarly opposed to each other.
本考案は前記外枠２及び内枠３を共に強度面と経済面が
適う形状寸法にしである。In the present invention, both the outer frame 2 and the inner frame 3 are shaped and dimensioned to suit both strength and economy.
即ち、第７図に示す如く内枠３の寸法を小さくしてあり
、ローラ転動面幅Ｂを外枠２のそれＡより小さくしであ
る。That is, as shown in FIG. 7, the dimensions of the inner frame 3 are made smaller, and the width B of the roller rolling surface is made smaller than that A of the outer frame 2.
併し、エンドローラ７．８，９．１０の直径は前記内枠
３のローラ転動面幅Ｂを基準にしてこれに適合すべく設
定し、同径のものが前述の如く配設しである。However, the diameters of the end rollers 7.8 and 9.10 are set to match the roller rolling surface width B of the inner frame 3, and those with the same diameter are arranged as described above. be.

It comes into contact with the flange portion 2''.
これはフォーク５に荷物がない場合にも同様のことが云
え、この時はフォーク５、フィンガバー６等の自重に依
り前述の如く作用する。The same thing can be said when there is no load on the fork 5, and in this case, the fork 5, finger bar 6, etc. act as described above due to their own weight.
本考案の昇降装置１に於ては内枠３の下部に、外枠２の
前側フランジ部２′に当接する摺動片１５が設けである
。In the lifting device 1 of the present invention, a sliding piece 15 is provided at the lower part of the inner frame 3 and comes into contact with the front flange portion 2' of the outer frame 2.
即ち、第１図並びに第４図に詳記する如くエンドローラ
１０近傍位置の内枠３にはブラケット１６を突設してこ
れに摺動片１５が付設しである。That is, as detailed in FIGS. 1 and 4, a bracket 16 is protruded from the inner frame 3 in the vicinity of the end roller 10, and a sliding piece 15 is attached to the bracket 16.
この摺動片１５は第３図に示すエンドローラ１０と外枠
２の前側フランジ部２′間に形成される隙間Ｃ（Ａ−Ｂ
）に依る内枠２のがたつきを防止する役目を果す。This sliding piece 15 is a gap C (A-B) formed between the end roller 10 and the front flange portion 2' of the outer frame 2 shown in FIG.
) to prevent the inner frame 2 from wobbling.
尚、上述はＣＪ型マストに就いて詳記したが第５図に示
