Retractable curtain assembly
A curtain retraction mechanism for a retractable curtain assembly, the curtain retraction mechanism comprising: a roller housing; a roller rotatably mounted within the roller housing and for rolling the sheet of curtain material on the roller; a torsion spring coupled to the roller for rotationally biasing the roller; and a tension adjustment member coupled to an end of the torsion spring and configured to move to engage and disengage from the roller housing, where the tension adjustment member is rotatable to selectively tension the torsion spring when disengaged from the roller housing.
一种用于可缩回帘幕组件的帘幕缩回机构，所述帘幕缩回机构包括：转辊壳体；转辊，该转辊可旋转地安装在转辊壳体内并且用于在转辊上卷动帘幕材料片；扭转弹簧，该扭转弹簧联接到转辊以用于旋转地偏压转辊；以及张力调节件，该张力调节件联接到扭转弹簧的端部，并且张力调节件被配置为进行移动以与转辊壳体接合和脱离，其中，张力调节件是可旋转的，以在与转辊壳体脱离时可选择地张紧扭转弹簧。
