Description

  The present invention relates to a mechanism for attaching a plate to which an end of a screen is fixed to a screen suspension member such as a head box or a bottom rail of a curtain device.

  In a curtain device including a screen suspension member such as a head box or a bottom rail, the screen is attached to the screen suspension member via a plate. The upper and lower ends of the screen are fastened to the upper surface of the upper plate and the lower surface of the lower plate via double-sided adhesive tape or staples, and rotate around the front ends of the respective plates. A mechanism for detachably attaching the plate, to which the screen end is fixed, to the head box and the bottom rail not from the side but from the upper surface or the lower surface is known. The mechanism supports the front support part of the plate in the vertical direction so that it can move in the front-rear direction on the front support part provided on the head box or the bottom rail, and supports the rear support part of the plate in the vertical direction on the rear support part. In addition, it is a method of positioning in the front-rear direction.

In this system, since the front end of the plate around which the screen end rotates is a free end that can swing, the tension and vibration acting on the screen extend around the front end of the plate to the fastening portion of the screen end. For this reason, the edge part of the screen fixed to the plate via the double-sided adhesive tape or the stapler may be peeled off from the plate by unexpected tension or vibration or both.
