Description

  The present invention relates to an attachment device for attaching curtain fabric of a raised curtain to a frame.

  In the curtain, the curtain fabric is suspended and supported from a frame, and the curtain fabric is lifted or lowered by pulling up the lower end portion of the curtain fabric with an elevating cord so that the amount of light can be adjusted.

  As one type of such a curtain, there is a double-type curtain that suspends and supports two curtain fabrics of different materials from a frame. For example, a lace fabric or other light-transmitting fabric is suspended and supported on the indoor side, and a light-shielding fabric is suspended and supported on the indoor side. By moving up and down, the amount of light collected can be adjusted appropriately.

  FIG. 11 shows a conventional example of a frame that suspends and supports two curtain fabrics. The frame 1 is formed as a profile having two accommodating portions 2a and 2b that can accommodate elevating devices 5a and 5b for independently elevating and lowering two pieces of fabric.

  A hook-and-loop fastener 3a is attached to the front surface of the frame 1, that is, a side surface on the indoor side, and a hook-and-loop fastener 3b is attached to the front surface of the attachment side 4 that extends downward from the intermediate wall of the housing portions 2a and 2b. And the upper edge part of each curtain fabric is each adhere | attached on the hook_and_loop | surface fasteners 3a and 3b.

  FIG. 12 shows another conventional frame example. The accommodating portions 7a and 7b of the frame 6 are the same as those of the frame 1 shown in FIG. A mounting side 9 is suspended and supported below the intermediate wall 8 of the housing portions 7a and 7b so as to be rotatable in the front-rear direction.

That is, a recess 10 constituting a hinge portion is formed at the lower end of the intermediate wall 8, and an engagement portion 11 that is rotatably held by the recess 10 is formed at the upper edge of the attachment side 9. The surface fasteners 3a and 3b are attached to the front surface of the frame 6 and the front surface of the attachment side 9, and the upper edge portions of the curtain fabrics are bonded to the surface fasteners 3a and 3b, respectively.
