Description
【考案の詳細な説明】
本考案は、所定のものより細い軸径のシャフトを本来の
軸径のシャフトと同等に使用するための補填用スリーブ
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a complementary sleeve for using a shaft having a smaller shaft diameter than a predetermined shaft diameter in the same manner as a shaft having the original shaft diameter.
一般にシャッターの巻取中心軸は、シャッターの横幅の
長短によって、強度的に十分な軸径のものが選択される
。Generally, the winding center shaft of the shutter is selected to have a shaft diameter sufficient for strength, depending on the width of the shutter.
一方、シャッター巻取ホイールはシャッター巻取中心軸
の両端部にそれぞれ装着されるものであるから、従来は
、それらもシャッター巻取中心軸の軸径に合った内径の
ものが数種類用意されていた。On the other hand, since shutter take-up wheels are attached to both ends of the shutter take-up center shaft, conventionally, several types of wheels were available with inner diameters that matched the shaft diameter of the shutter take-up center shaft. .
本考案は、細い軸径の巻取中心軸であっても、太い軸径
用のシャッター巻取ホイールに装着できるようにするた
めの所定の肉厚を有する補填用スリーブを提案するもの
で、以下、図示した実施例に従って本考案を説明する。The present invention proposes a supplementary sleeve with a predetermined wall thickness so that even if the winding center shaft has a small diameter, it can be attached to a shutter winding wheel for a thick shaft diameter. , the invention will be explained according to the illustrated embodiments.
Ａは、所定の肉厚を有し、シャッター巻取ホイールＢの
軸受部１に装着されるほぼ円筒形の本考案に係る合成樹
脂製スリーブで、軸線４を含む平面上に設けられた縦割
溝５によって２分割された可撓部３と、該縦割溝が設け
られていない基部２とからなる。A is a substantially cylindrical synthetic resin sleeve according to the present invention having a predetermined wall thickness and attached to the bearing part 1 of the shutter take-up wheel B, and is vertically divided on a plane including the axis 4. It consists of a flexible part 3 divided into two parts by a groove 5, and a base part 2 in which the longitudinal groove is not provided.
６は、可撓部３の外側面に基部２から離れて設けられた
位置決め突起で、前記軸受部１の対応する透孔７に嵌合
する。Reference numeral 6 denotes a positioning projection provided on the outer surface of the flexible portion 3 at a distance from the base 2, and is fitted into a corresponding through hole 7 of the bearing portion 1.
８は該可撓部３の変形を容易にするための環状溝、９は
可撓部３の口縁に設けられた張出し部である。Reference numeral 8 indicates an annular groove for facilitating deformation of the flexible portion 3, and reference numeral 9 indicates an overhang portion provided at the mouth edge of the flexible portion 3.
本実施例に係るスリーブＡは、シャッター巻取ホイール
Ｂの軸受部にあらかじめ装着しておくもので、すなわち
、本来該軸受部に装着されるべきシャッター巻取中心軸
の軸径より細い軸径のシャッター巻取中心軸を装着する
場合に、軸径の差に等しい所定の肉厚のスリーブを選択
し、該スリーブの基部２を先にして該軸受部に挿入し、
位置決め突起６が障害となれば、該可撓部を内傾させて
さらに挿入し、該突起は復元力で透孔７に嵌合して固定
される。The sleeve A according to this embodiment is installed in advance on the bearing part of the shutter winding wheel B. In other words, the sleeve A has a shaft diameter smaller than that of the shutter winding center shaft that should originally be mounted on the bearing part. When installing the shutter winding center shaft, select a sleeve with a predetermined wall thickness equal to the difference in shaft diameter, insert the sleeve into the bearing portion with the base 2 of the sleeve first,
If the positioning protrusion 6 becomes an obstacle, the flexible portion is tilted inward and further inserted, and the protrusion is fitted into the through hole 7 by restoring force and fixed.
このようにして、見かけ上、細くなった該軸受部に巻取
中心軸が装着される。In this way, the winding center shaft is attached to the apparently thin bearing section.
なお、本考案は図示した実施例に限られるものではなく
、例えば、位置決め突起を可撓部３の内側面に設けるこ
ともできる。Note that the present invention is not limited to the illustrated embodiment; for example, positioning protrusions may be provided on the inner surface of the flexible portion 3.
この場合、該スリーブは可撓部を外側に変形することに
よって、位置決め突起をシャッター巻取中心軸の対応す
る小孔に嵌合させて、あらかじめシャッター巻取中心軸
に装着しておく必要がある。In this case, the sleeve must be attached to the shutter take-up center shaft in advance by deforming the flexible portion outward so that the positioning protrusion fits into the corresponding small hole of the shutter take-up center shaft. .
本考案は以上のように構成されているから、シャッター
の巻取ホイールの軸受部に、該軸受部の内径より細いシ
ャッター巻取中心軸を装着することができる。Since the present invention is configured as described above, it is possible to attach the shutter winding center shaft, which is thinner than the inner diameter of the bearing part, to the bearing part of the winding wheel of the shutter.
