【考案の詳細な説明】
本考案は、キヤスター、更に詳しく言えば、極
めて簡単な構造にして重負荷に充分耐えると同時
に組立作業性を向上し安価に製作することができ
るように工夫されたキヤスターに関するものであ
る。[Detailed description of the invention] The present invention is a caster, more specifically, a caster that has an extremely simple structure, can sufficiently withstand heavy loads, improves assembly workability, and can be manufactured at a low cost. It is related to.
従来のキヤスターには、構造の異なるいくつか
のものがあるが、代表的なもの2種類について説
明すれば次の通りである。 There are several types of conventional casters with different structures, but two typical types are explained below.
第1のものは、板状の取付座板、上段ボール受
金具を突設したバーリング部に咬めて固定した車
輪取付本体、下段ボール受金具、該下段ボール受
金具と上記取付座板とを固着するピン、上記取付
座板と上段ボール受金具とによつて保持される上
段ボール、そして上記車輪取付本体と下段ボール
受金具とによつて保持される下段ボールとから形
成されたキヤスターである。 The first one consists of a plate-shaped mounting seat plate, a wheel mounting body with an upper corrugated ball holder attached to a protruding bar ring, a lower corrugated ball holder, and the lower corrugated ball holder and the above mounting plate fixed together. The caster is formed of a pin, an upper corrugated board held by the mounting seat plate and the upper corrugated ball holder, and a lower corrugated board held by the wheel attachment body and the lower corrugated ball holder.
しかしながら、このようなキヤスターは、上記
取付座板と下段ボール受金具とがピンにより固着
され、上段ボール受金具が車輪取付本体のバーリ
ング部に咬めて固定されていること等に起因し
て、運搬機械に積載される荷物の重量が大きい場
合やキヤスターの走行する通路に起伏がある場合
には、キヤスターに重負荷が加わり、前記ピンに
よる固着部分や咬め部分に負荷が集中して作用し
緩みや変形が生じる。 However, such casters are difficult to transport due to the fact that the mounting seat plate and the lower corrugated ball holder are fixed with pins, and the upper corrugated ball holder is fixed to the burring part of the wheel mounting body. When the weight of the load loaded on the machine is large or when the path the casters travel on has undulations, a heavy load is applied to the casters, and the load concentrates on the fixed and engaged parts of the pins, causing them to loosen or become loose. Deformation occurs.
その結果、上記の部分に亀裂や磨耗を生じ、車
輪取付本体の回転が円滑に行えなくなつたりキヤ
スターにがたつき音が発生したりする。そして場
合によつては、衝撃によつて上下段ボールが割れ
たりピンが外れて車輪取付本体が脱落することも
ある。 As a result, cracks and wear occur in the above-mentioned parts, making it impossible for the wheel mounting body to rotate smoothly and causing rattling noises in the caster. In some cases, the impact may cause the upper and lower cardboard boxes to crack or the pins to come off, causing the wheel mounting body to fall off.
第2のものは、板状の取付座板、上段ボール受
金具を突設したバーリング部に咬めて固定した車
輪取付本体、上端部が上記取付座板に咬めて固着

つて保持される上段ボール、そして上記車輪取付
本体と筒状部材の下段ボール受部とによつて保持
される下段ボールとから形成されたキヤスターで
ある。 The second one consists of a plate-shaped mounting seat plate, a wheel mounting body with an upper corrugated ball holder attached to a protruding bar ring, the upper end of which is fixed to the mounting seat plate, and a lower corrugated ball holder on the lower end. a cylindrical member integrally formed with a cylindrical member, an upper corrugated board held by the mounting seat plate and an upper corrugated ball holder, and a cylindrical member held by the wheel attachment body and a lower corrugated board holder of the cylindrical member. It is a caster formed from lower corrugated cardboard.
しかしながら、このようなキヤスターも、上記
取付座板と筒状部材とが咬めて固着され、上段ボ
ール受金具が車輪取付本体のバーリング部に咬め

もの同様にキヤスターに重負荷が加わり、前記取
付座板と筒状部材との咬め部分及び上段ボール受
金具と車輪取付本体のバーリング部との咬め部分
に負荷が集中して作用し緩みや変形が生じる。 However, in such a caster, the mounting seat plate and the cylindrical member are engaged and fixed together, and the upper corrugated ball holder is engaged and fixed to the burring part of the wheel mounting body, and so on. Similar to the case of 1, a heavy load is applied to the caster, and the load concentrates on the engagement part between the mounting seat plate and the cylindrical member and the engagement part between the upper corrugated board bracket and the burring part of the wheel attachment body, causing loosening and loosening. Deformation occurs.
このような代表的な2種類のキヤスターにおけ

厚くしたり、或いは強固な材料を用いたり特殊な
焼入れを施す等の他、咬め部分を溶接する等の手

目を有する以上長期にわたつて重荷重に耐え得る
ものではなかつた。 In order to alleviate the drawbacks of these two typical types of casters, for example, the material of the holder may be made thicker, stronger material may be used, special hardening may be applied, or the engagement portion may be welded. However, in either case, the number of parts is large and the cost is high in terms of workability, and the appearance is not good, and since it has a joint, it will be heavy over a long period of time. It was not able to withstand the load.
本考案の目的は、以上に説明したような従来の

第1図及び第2図に示す本考案のキヤスターの
一実施例において、1は取付座板であり、該取付
座板1は、取付座板本体部2と窪み部3と上段ボ
ール受部4と下段ボール受部5とから形成されて
いる。 In one embodiment of the caster of the present invention shown in FIGS. 1 and 2, 1 is a mounting seat plate, and the mounting seat plate 1 includes a mounting seat plate main body portion 2, a recessed portion 3, and an upper corrugated board receiving portion 4. and a lower corrugated board receiving part 5.
上記取付座板本体部2の隅部には、4個の取付
用孔6…が設けられている。 Four mounting holes 6 are provided at the corners of the mounting seat plate main body 2.
上記窪み部3は、上記取付座板本体部2の内側
端部を環状に略垂直下方に折曲した後に内側上方
に折曲して形成されたものである。 The recessed portion 3 is formed by bending the inner end portion of the mounting seat plate main body portion 2 approximately vertically downward into an annular shape and then bending the inner end portion upwardly inward.
上記上段ボール受部4は、上記窪み3を延長し
て内側下向きに湾曲するように形成されたもので
あり、上記下段ボール受部5は、上記上段ボール
受部4を略垂直下方に延長した後に外側上向きに
湾曲するように形成されたものである。 The upper corrugated board receiving part 4 is formed by extending the recess 3 and curved inwardly downward, and the lower corrugated board receiving part 5 is formed by extending the upper corrugated board receiving part 4 substantially vertically downward. It is formed so that it later curves outward and upward.
7は車輪取付本体であり、該車輪取付本体7

輪取付本体7のボール受部8とによつて保持され
ている。 11 is a lower corrugated board, and the lower corrugated board 11
is held by the lower cardboard receiving portion 5 of the mounting seat plate 1 and the ball receiving portion 8 of the wheel mounting body 7.
以上のように構成した本考案のキヤスターによ
れば、取付座板本体部と窪み部と上段ボール受部
と下段ボール受部とを一体に形成して取付座板を
構成したことにより、重荷重に対して充分に耐え
ることができ、従来のようにピンによる固着部分
や咬め部分を全く有しないことにより緩みを生じ
てがたつき音を発生したり車輪取付本体が脱落す
るようなことがない。 According to the caster of the present invention constructed as described above, since the mounting seat plate is constructed by integrally forming the mounting seat plate main body, the recessed portion, the upper corrugated ball receiving portion, and the lower corrugated ball receiving portion, it is possible to withstand heavy loads. Since it does not have any pin-fastened parts or biting parts unlike conventional products, it does not loosen, causing rattling noises, or causing the wheel mounting body to fall off. .
特に、取付座板に窪み部が設けられていること
により、取付座板の強度を増すと共に上段ボール
の脱落を防止することができる。 In particular, by providing the mounting seat plate with the recessed portion, it is possible to increase the strength of the mounting seat plate and to prevent the upper corrugated board from falling off.
そして、ボール受部が車輪取付本体の上端部に
上向きに湾曲するように形成され、該ボール受部
の上面によつて上段ボールの下側を保持し上記ボ
ール受部の下面によつて下段ボールの上側を保持
するように形成されていることにより、上段ボー
ルと下段ボールとが上下方向に並ぶように配置さ

形成される取付座板の筒状部の内径を大きくする
ことができるから、これによつて、キヤスター全
体の強度を著しく増すと共にその組立作業性を向
上させることができる。 A ball receiving part is formed at the upper end of the wheel mounting body so as to curve upward, and the upper surface of the ball receiving part holds the lower side of the upper corrugated cardboard, and the lower surface of the ball receiving part holds the lower corrugated cardboard. By being formed so as to hold the upper side, the upper corrugated cardboard and the lower corrugated cardboard are arranged vertically side by side, and the mounting seat plate formed by the upper corrugated cardboard receiving part and the lower corrugated cardboard receiving part. Since the inner diameter of the cylindrical portion can be increased, the overall strength of the caster can be significantly increased, and the ease of assembling the caster can be improved.
次に、キヤスター全体が取付座板と車輪取付本
体と上段ボールと下段ボールとから構成されてい
ることにより、構造が極めて簡単であり部品点数

ることができる。 Secondly, since the entire caster consists of a mounting seat plate, a wheel mounting body, an upper corrugated board, and a lower corrugated board, the structure is extremely simple and the number of parts is small, which improves assembly workability and reduces costs. It can be manufactured.
更に、このように構成されていることにより、
長期にわたつて故障することなく常に安定した走
行が得られるものである。 Furthermore, with this configuration,
This allows for stable running over a long period of time without any failures.
