Description

【考案の詳細な説明】本考案はシャッタードアの巻取ドラムに関するものであ
る。[Detailed Description of the Invention] The present invention relates to a winding drum for a shutter door.

さらに詳しくいえば、複数個の巻取ホイールと、これら
を連結するステーとの関連構成に関するものである。More specifically, the present invention relates to a structure related to a plurality of winding wheels and a stay that connects them.

従来巻取ホイールとステーとの結合は第１図と第２図及
び第３図のようにして行っていた。Conventionally, the winding wheel and the stay were connected as shown in FIGS. 1, 2, and 3.

第１図の場合はアングル状のステー２の場合、第２図は
パイプ型のステー２ａの場合で、それぞれ巻取ホイール
の側板３にステー２又は２ａの外形にほぼ合致した穴４
又は４ａを設け、該穴に側方からステーを挿入し、溶接
していた。The case of Fig. 1 shows the case of the stay 2 having an angle shape, and the case of Fig. 2 shows the case of the stay 2a of the pipe shape.The side plate 3 of the winding wheel has a hole 4 that almost matches the outer shape of the stay 2 or 2a, respectively.
Or 4a was provided, and the stay was inserted into the hole from the side and welded.

この構造ではステーを立てた状態で溶接しない限り横向
姿勢で溶接せざるを得ない。With this structure, unless the stay is welded in an upright position, welding must be done in a horizontal position.

従って作業性が悪く、溶接の精度悪化の原因となってい
た。Therefore, the workability was poor, and this caused deterioration in welding accuracy.

又第３図の場合は上記問題点を改良し、巻取ホイール１
の外周面５にアングル状のステー２の外形に合せたＶＲ
６をプレス加工しておき、これにステー２を載せ、巻取
ホイール１に対し溶接腰溶接作業をし易くしている。In addition, in the case of Fig. 3, the above problem is improved and the winding wheel 1 is
VR that matches the outer shape of the angular stay 2 on the outer peripheral surface 5 of
6 is pressed, and the stay 2 is placed on it to facilitate welding work to the winding wheel 1.

この構成で、第１図、第２図の場合より溶接し易くなっ
たが、ステー２の外形と等しい■溝のため、両者間の隙
間の発生により、ステーの座りが不安定の場合があり、
いまひとつ溶接精度上好ましくない。With this configuration, it is easier to weld than in the cases shown in Figures 1 and 2, but since the groove is the same as the outer diameter of the stay 2, there is a gap between the two, which may cause the stay to sit unstable. ,
This is not desirable in terms of welding accuracy.

第４図は本考案の第１実施例である。FIG. 4 shows a first embodiment of the present invention.

第４図の場合に於てはステー２ａの下半分を呑込む半円
筒状の溝７を設け、この上部両側に水平段部８を設け、
これに続いて外に向って傾斜する斜面９が対称的に設け
られている。In the case of FIG. 4, a semi-cylindrical groove 7 that swallows the lower half of the stay 2a is provided, and horizontal step portions 8 are provided on both sides of the upper part.
This is followed symmetrically by an outwardly inclined slope 9.

第５図において、第４図の半円筒状の溝７が■型溝１１
とその上部の半円筒状面の一部１２とで構成されている
。In FIG. 5, the semi-cylindrical groove 7 in FIG.
and a part 12 of a semi-cylindrical surface on the top thereof.

さて、第４図と第５図の両実施例ともパイプ状ステー２
ａを水平段部８より下の円筒状面に密着するよう嵌め、
水平段部８の部分で溶接するが、この半円筒状面部分で
両者が密着している上に段部８より上が外に向って開い
ているので溶接作業がし易くなっている。Now, in both the embodiments shown in FIGS. 4 and 5, the pipe-shaped stay 2
Fit a into tight contact with the cylindrical surface below the horizontal step 8,
Welding is performed at the horizontal stepped portion 8, and since the two are in close contact with each other at this semi-cylindrical surface portion and the portion above the stepped portion 8 is open outward, welding work is facilitated.

なお以上の実施例で、ステーがパイプ状でない場合でも
、その断面形状の一部が巻取ドラムの嵌合溝の一部と、
同一形状にして密着するようにすれば、他の断面形状の
ステーでも同様に高精度の溶接ができる。In the above embodiments, even if the stay is not pipe-shaped, part of its cross-sectional shape is part of the fitting groove of the winding drum.
As long as the stays have the same shape and are in close contact with each other, stays with other cross-sectional shapes can be similarly welded with high precision.

本考案は以上の如くであるから、巻取ホイールにステー
を溶接で固着する場合、ステーを載せた状態で溶接がで
きるので作業性が向上すると共に、溶接強度の優れた巻
取ドラムを得ることができる。The present invention is as described above, so that when a stay is fixed to a winding wheel by welding, welding can be performed with the stay placed on it, which improves work efficiency and provides a winding drum with excellent welding strength. Can be done.

溶接部において溝とステーとが密接し、隙間が生じない
ので、溶接し易い。Since the groove and the stay are in close contact with each other in the welded part and no gap is created, welding is easy.

特に溶接部より上を上方に向は開放しておくので溶接が
し易く、かつ強固に溶接できるので強度上優れた巻取ド
ラムを提供することができる。In particular, since the area above the welding part is left open upwardly, welding is easy to perform, and since welding can be performed firmly, it is possible to provide a winding drum with excellent strength.
