Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、綿をつむぐ機械その他の機械類や買い物用
カートその他の運搬車などに於いて、回転輪として取り
付けて用いる防塵カバー付キャスターの改良に関するも
のである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a caster with a dust-proof cover that is used as a rotating wheel in a cotton shaving machine and other machines, a shopping cart, and other transport vehicles. It is about improvement.
従来よりキャスターは、回転輪の働きをするために種々
の処で使用されてきたが、何れも粉塵や髪の毛その他の
ごみ類が回転輪の部分に絡みつきやすかった。Conventionally, casters have been used in various places to function as a rotary wheel, but in all of them, dust, hair, and other debris are easily entangled with the rotary wheel.
すなわち従来のキャスターは、車軸と車輪の取り付け部
が露出したままであったり、例えば第４図に示すように
外カバー（10）が取り付けられていた場合であっても、
車輪（４）側面と外カバー（10）の間に間隙（17）があ
り、この間隙（17）からごみ類が外カバー（10）内に入
り込んで車輪（４）の回転不良を起こすことが多かっ
た。That is, in the conventional caster, even when the attachment portion of the axle and the wheel is exposed or the outer cover (10) is attached as shown in FIG. 4,
There is a gap (17) between the side surface of the wheel (4) and the outer cover (10), and debris may enter the outer cover (10) through the gap (17) and cause the wheel (4) to rotate poorly. There were many.
また、車輪（４）の中心部に設けたベアリング（９）の
ハウジング（７）は、無理な曲げ加工によりその側部
（7a）が形成されていたので、場合によってはベアリン
グ（９）が押圧されて回転不良を起こすことがあった。Further, the housing (7) of the bearing (9) provided at the center of the wheel (4) has its side portion (7a) formed by forcible bending, so that the bearing (9) is pressed in some cases. It sometimes caused a rotation failure.
そこでこの考案では、車輪と車軸の連結部にごみ類が入
り込む虞れのない状態の外カバー及びカラーの防塵二重
構造を設けて、綿をつむぐための機械の中に組み込んだ
り、スーパーマーケットなどの髪の毛その他のごみ類が
からみやすい場所での使用であっても、車輪の回転不良
が生じることのない防塵カバー付キャスターを提供しよ
うとするものである。Therefore, in this invention, an outer cover and a dust-proof double structure of a collar are provided in a state where dust and the like are not likely to enter the connecting portion between the wheel and the axle, and are incorporated in a machine for picking up cotton, such as in a supermarket. It is an object of the present invention to provide a caster with a dust-proof cover that does not cause a wheel rotation failure even when used in a place where hair or other dust is likely to be entangled.
さらにこの考案は、前記車輪と車軸の連結部に設けたカ
ラーの一部がベアリングのハウジングの側部を形成する
ようにし、ハウジングの無理な曲げ加工によるベアリン
グの回転不良が生じることのない防塵カバー付キャスタ
ーを提供しようとするものである。Further, according to the present invention, a part of the collar provided at the connecting portion between the wheel and the axle forms a side portion of the housing of the bearing, and the dust-proof cover which does not cause rotation failure of the bearing due to excessive bending of the housing. It is intended to provide casters with an attachment.
この考案の防塵カバー付キャスターは、中心部に設けた
貫通孔に筒形状のスリーブを左右両側に突出するように
取り付け、前記スリーブの外周面に接するベアリングを
内部に設けた車輪の左右両側に、中心部に穴を設けた円
板形状の外カバーを配し、前記穴及び貫通穴に車軸を貫
通させ、外カバーの外周を車輪のトレッド部の内側窪み
部に接触させると共に、一部を前記ベアリングのハウジ
ングの側部を構成する形状としたカラーを前記車輪と外
カバーとの間に生ずる隙間に介在するように前記スリー
ブの左右両側外周に嵌め込んだものとしている。The caster with a dustproof cover of the present invention has a cylindrical sleeve attached to the through hole provided at the center so as to project to the left and right sides, and bearings contacting the outer peripheral surface of the sleeve are provided on both the left and right sides of the wheel provided inside. A disk-shaped outer cover having a hole in the center is arranged, the axle is passed through the hole and the through hole, and the outer periphery of the outer cover is brought into contact with the inner recess of the tread portion of the wheel, and a part of the outer cover is provided. A collar having a shape forming a side portion of the housing of the bearing is fitted to the outer circumferences of the left and right sides of the sleeve so as to be interposed in a gap formed between the wheel and the outer cover.
さらに、車輪を合成樹脂製にすると共に、外カバーを合
成樹脂製のシール部の内側に金属製の本体部を取り付け
て構成し、前記シール部を車輪に接触させた構成とする
ことができる。Further, the wheel may be made of synthetic resin, and the outer cover may be configured by attaching a metal main body to the inside of the synthetic resin seal portion, and the seal portion may be in contact with the wheel.
また、外カバーの外周を車輪のトレッド部の内側窪み部
の面に沿うように内から外に向かって伸延させた形状と
してもよい。Further, the outer periphery of the outer cover may be shaped to extend from the inside to the outside along the surface of the inner recess of the tread portion of the wheel.
前記のように外カバーの外周を車輪のトレッド部の内側
窪み部に接触させ、さらに、一部を前記ベアリングのハ
ウジングの側部を構成する形状としたカラーを前記車輪
と外カバーとの間に生ずる隙間に介在するようにスリー
ブの左右両側外周に嵌め込んだキャスターでは、ごみ類
が外カバー内に入り込むことが殆どなく、また例え何か
のはずみでごみ類が外カバー内に入り込んだとしても、
ごみ類はカラーに遮られ車輪の連結部に入り込むことは
ない。As described above, the outer periphery of the outer cover is brought into contact with the inner recess of the tread portion of the wheel, and further, a collar having a shape forming a side portion of the housing of the bearing is provided between the wheel and the outer cover. With the casters that are fitted on the left and right outer peripheries of the sleeve so as to intervene in the gaps that occur, dust is unlikely to enter the outer cover, and even if dust enters the outer cover due to something ,
Garbage is blocked by the collar and does not enter the wheel connection.
さらに、外カバーの本体部を金属製にすると強度が大で
あり、且つシール部及び車輪を共に合成樹脂製とし、こ
のシール部と車輪を接触させると接触部が同質の材料か
ら成るため破損や摩耗の虞れは少なくなる。Furthermore, if the main body of the outer cover is made of metal, the strength will be great, and both the seal and the wheel will be made of synthetic resin. The risk of wear is reduced.
また、外カバーの外周を内側窪み部に於いて内から外に
向かって伸延させた形状とすることにより、ごみ類の外
カバー内への進入をより防ぐことができる。Further, by making the outer periphery of the outer cover extend from the inside toward the outside at the inner recess, it is possible to further prevent dusts from entering the outer cover.
