  By the way, when washing the fabric or replacing it with a new fabric, it is necessary to remove the fabric from the head rail.

  However, in Patent Document 1, since the fabric is fixed to the head rail, it cannot be removed, and washing and replacement are virtually impossible.

  On the other hand, in Patent Document 2, since the cloth is removable, it can be washed and replaced. However, if an unexpected external force is applied to the cloth by hooking the body or an object on the cloth, the cloth is removed from the head rail. May come off. In addition, a load of fabric is always applied to the surface fastener, and if an impact is applied during the lifting operation in this state, the engagement of the surface fastener may be disengaged and the fabric may be detached from the head rail.

  The present invention has been made in view of this point, and an object of the present invention is to easily remove and remove the fabric and to surely prevent the fabric from falling.

  In order to achieve the above object, the present invention is characterized in that a press-fitting method is adopted instead of the engaging method by the hook-and-loop fastener.

  Specifically, the present invention is directed to a suspension type light shielding device in which a support frame is attached to a fixed side in a room with a bracket, and a light shielding member is suspended and supported by the support frame so as to be lifted and lowered. A solution was taken.

  That is, according to the present invention, a press-fitting bar is attached to the upper end of the light-shielding member, and a press-fitting groove having a dovetail shape in which the press-fitting bar is press-fitted to the lower surface of the support frame so as to be inserted and removed from one end side of the support frame. Is formed over the entire length in the longitudinal direction.

  According to this invention, when washing the fabric or replacing with a new fabric, the press-fitting bar is pulled out from the press-fitting groove by holding the upper end of the fabric with the hand and pulling it sideways along the support frame. The fabric can be easily removed from the support frame. Conversely, when attaching the fabric to the support frame, the fabric can be easily attached to the support frame simply by holding the upper end of the fabric by hand and press-fitting the press-fitting bar into the press-fit groove from one end of the support frame. In this attached state, the press-fitting bar is press-fitted into the dovetail-shaped press-fitting groove from one end of the support frame. Even if an impact is applied to the fabric, the fabric can be reliably prevented from falling.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The front plate 18 is integrally formed of a pentagonal upper half plate portion 19 and a rectangular thin lower half plate portion 20. A screw insertion hole 19 a is formed on the upper end side of the upper half plate portion 19. A second receiving piece 21 that receives the other end in the width direction of the lower surface of the head rail 7 is bent at the lower end of the lower half plate portion 20. Further, at both ends in the width direction of the upper half plate portion 19, guide frames 22 extending toward the rear plate 14 are respectively projected integrally in parallel. These guide frames 22 are placed on the guide pieces 16a of the top plate 13, and the front plate 18 is supported so as to be movable toward and away from the rear plate 14 on the other end side (inner side) of the top plate 13. ing.

  At the center of the back surface of the top plate 13 in the width direction, a brazing material 23 having a circular cross section is integrally fixed along the longitudinal direction. A screw hole 23a that opens to the front plate 18 side is formed in a substantially half region on the indoor side of the casing 23, and a caulking projection 23b projects from the end on the window side, and the caulking projection 23 b is inserted into the caulking hole 14 b of the rear plate 14, and the brazing material 23 is caulked and joined to the rear plate 14. Then, with the first receiving piece 17 and the second receiving piece 21 receiving the both ends of the lower surface of the head rail 7 in the width direction, the screws 24 are passed through the screw insertion holes 19a of the front plate 18 and The front plate 18 is fixed so as not to move by being screwed into the screw hole 23a.

  Next, the installation procedure of the roman shade A will be described.

  First, the two brackets 12 are attached to the fixed side (ceiling, wall, window frame) in the room with an interval depending on the length of the head rail 7. When the fixed side is the ceiling, the screws are inserted into the two screw insertion holes 13a of the top plate 13 to fix the bracket 12 to the ceiling. When the fixed side is a wall or a window frame, the bracket 12 is fixed to the wall by inserting screws through the two screw insertion holes 14a of the rear plate 14. At this time, the screws 24 screwed into the screw holes 23 a of the collar member 23 are loosened in advance to move the front plate 18 away from the rear plate 14, and the distance between them is made larger than the width of the head rail 7.

  Next, the head rail 7 is bridged to the two brackets 12, and the first receiving piece 17 of the rear plate 14 and the second receiving piece 21 of the front plate 18 receive the width direction both ends of the lower surface of the head rail 7.

  Thereafter, the screw 24 is tightened to bring the front plate 18 closer to the rear plate 14, and the head rail 7 is clamped so as not to move between the front plate 18 and the rear plate 14.

  Thereafter, the press-fitting bar 9 of the window side fabric 1b is press-fitted into the window side rail portion 8b from one end side of the head rail 7 as shown by an arrow in FIG. One end of each of the window-side operation cords 5b is inserted into two rows of rings 4 in order from the top, and connected to the connector 6 of the lowermost weight bar 2.

  Similarly, after the press-fitting bar 9 of the indoor fabric 1a is press-fitted into the indoor rail portion 8a from one end side of the head rail 7 as shown by the arrow in FIG. 3, the indoor fabric 1a is suspended and supported by the head rail 7. One end of the two indoor operation cords 5a is inserted into the two rows of rings 4 in order from the top, and is connected to the connector 6 of the bottom weight bar 2. Thereby, the installation of the double type roman shade A is completed.

  In the Roman shade A configured as described above, when the indoor side operation cord 5a or the window side operation cord 5b is pulled downward, the indoor side fabric 1a or the window side fabric 1b rises and stops when the hand is loosened. During this time, the connecting tool 6 and the ring 4 that are vertically adjacent to each other come into contact with each other, so that the fabric 1a (1b) between them is folded up with the tack bar 3 as a boundary to be rolled up. The cloth 1a (1b) is lowered by pulling the operation cord 5a (5b) slightly and then loosening the hand. These raising / lowering stopping operations are controlled by the stopper mechanism 10a (10b).

  As described above, in this embodiment, when washing the fabrics 1a and 1b or when replacing the fabrics 1a and 1b with new fabrics 1a and 1b, hold the upper ends of the fabrics 1a and 1b with the hand along the head rail 7. When pulled sideways, the press-fitting bar 9 is pulled out from the rail portions 8a and 8b, and the fabrics 1a and 1b can be easily removed from the head rail 7. On the contrary, when the fabrics 1a and 1b are attached to the head rail 7, the fabric 1a and 1b are simply held by holding the upper ends of the fabrics 1a and 1b and press-fitting the press-fitting bar 9 into the rail portions 8a and 8b from one end side of the head rail 7. 1a and 1b can be easily attached to the head rail 7. In this mounted state, the tack bar 3 is press-fitted into the rail portions 8a and 8b having a cross-sectional dovetail shape, so that an unexpected external force is applied to the fabrics 1a and 1b by hooking a body or an object on the fabrics 1a and 1b. Or, even if an impact at the time of lifting operation is applied to the fabrics 1a and 1b, the fabrics 1a and 1b can be reliably prevented from falling.

  In this embodiment, since the head rail 7 is received from both sides by the first receiving piece 17 of the rear plate 14 of the bracket 12 and the second receiving piece 21 of the front plate 18, the fabric 1a (1b) and the head The screw 24 can be easily moved back and forth so that the load of the rail 7 is not applied to the screw 24. In addition, since the operator does not have to support the head rail 7 when removing or attaching the head rail 7, it is possible to easily remove and attach the head rail 7. Further, even if the screw 24 is loosened during the removal operation, the head rail 7 does not fall, so that the removal operation can be performed safely.

  Further, in this embodiment, the front plate 18 is movably supported on the bracket body 15, receiving pieces 17 and 21 are formed on the bracket body 15 and the front plate 18, and the front plate 18 is fixed with screws 24. Therefore, the structure of the bracket 12 can be simplified and the manufacturing cost can be reduced.
