It is a cross-sectional view of a head rail. FIG. 4 is a sectional view taken along the line 4-4 in FIG. 1. FIG. 5 is a sectional view taken along line 5-5 in FIG. 1.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 are diagrams showing a roman shade according to an embodiment of the present invention.

  The roman shade 10 includes a head rail 12, and the head rail 12 is fixed to a fixed surface by a bracket 60 described later.

  The head rail 12 roughly includes a front wall surface (front wall) 12a, a rear wall surface (rear wall) 12b, and an upper wall surface 12c.

  An upper portion of the front wall surface 12a is a fabric attachment portion 12d, and the upper end of the first fabric 16 is attached and suspended by a detachable coupling means 15 such as a hook-and-loop fastener. Further, a lower portion of the rear wall surface 12b is a fabric attachment portion 12e, and the upper end of the second fabric 18 is attached and suspended by the detachable coupling means 15. A plurality of cord rings 20 are attached to the rear surfaces of the first fabric 16 and the second fabric 18 with a predetermined interval in the width direction and a predetermined interval in the vertical direction.

  As shown in FIG. 3, the internal space surrounded by the front wall surface 12 a, the rear wall surface 12 b, and the upper wall surface 12 c of the head rail 12 is at least a lower holding portion 13 and an upper holding portion by a plurality of internal partition wall surfaces. Part 14 is defined.

  The lower holding portion 13 has a substantially square cross section, and the upper side, that is, the upper surface 13a, the lower side, that is, the lower surface 13b, is horizontal, and the front side, that is, the front surface 13c, and the rear side, that is, the rear surface 13d, are vertical. Be placed. The front surface 13c is a part of the front wall surface 12a, and the rear surface 13d is a part of the rear wall surface 12b. In addition, a first opening 13e is formed in the longitudinal direction on the lower surface 13b.

  One upper holding portion 14 has a substantially square cross section, and each side, that is, each surface is disposed so as to form an angle (for example, 45 degrees) with respect to the horizontal and vertical directions. Therefore, each side, that is, each surface includes a front upper surface 14a, a front lower surface 14b, a rear upper surface 14c, and a rear lower surface 14d. Further, the center position of the cross-sectional shape of the upper holding part 14 is offset rearward from the center position of the lower holding part 13. Therefore, a part of each of the rear upper surface 14c and the rear lower surface 14d is above the fabric attachment portion 12e for the second fabric 18 on the rear wall surface 12b and protrudes rearward. Then, the rear lower surface 14d is opened facing the obliquely rear lower side of the head rail 12, and is located on the rear upper side of the head rail 12 with respect to the fabric attachment portion 12e for the second fabric 18 of the rear wall surface 12b. A second opening 14e is formed. Further, a corner portion, that is, a ridge line 14 f that is an intersection of the front upper surface 14 a and the rear upper surface 14 c intersects the upper wall surface 12 c of the head rail 12.

  The front surface side and the rear surface side of the upper wall surface 12c of the head rail 12 are flange portions 12g and 12h, and the flange portions 12g and 12h are locked by a bracket 60 fixed to a window frame or the like.

  As shown in FIG. 4, the first winding drum assembly 22 is in the lower holding portion 13 of the head rail 12, and the second winding drum assembly 24 is in the upper holding portion 14. A plurality of them are arranged at an appropriate distance in the longitudinal direction.

  The first and second take-up drum assemblies 22 and 24 have first and second take-up drums 26 and 28, and first and second take-up drums 26 and 28, respectively, which rotatably support the first and second take-up drums 26 and 28, respectively. Second drum receivers 30 and 32 and first and second openings 34 and 36 formed at the bottoms of the first and second drum receivers 30 and 32 are provided. Each of the first and second winding drums 26 and 28 is coupled to rotate integrally with drive shafts 46 and 47 provided over substantially the entire length of the head rail 12 in the longitudinal direction.

  The first and second winding drum assemblies 22 and 24 are provided such that the positions of the first and second openings 34 and 36 overlap the positions of the first opening 13e and the second opening 14e of the head rail 12, respectively. The bottoms of the first and second drum receivers 30 and 32 engage with the first and second openings 13e and 14e, respectively, and the position of the axis of the second winding drum 28 is the axis of the first winding drum 26. It is fixed in the lower holding part 13 and the upper holding part 14 in a state of being shifted to the rear side of the head rail 12 from the position.

  Therefore, the first drum receiver 30 of the first winding drum assembly 22 is horizontal with the first and second winding drum assemblies 22 and 24 fixed in the lower holding portion 13 and the upper holding portion 14, respectively. However, the second drum receiver 32 of the second winding drum assembly 24 is inclined. With this arrangement, the front and rear direction of the head rail 12 is compared to the case where the second drum receiver 32 is arranged in the same posture as the first drum receiver 30 and shifted in the front and rear direction of the head rail 12 while ensuring the size of the opening 14e. The dimensions have been shortened. In addition, although the second winding drum 28 and the first winding drum 26 are displaced from each other in axial center, some of them overlap each other in the front-rear direction, so that the second drum receiver 32 is attached to the first drum. Compared with a case where the head rail 12 is completely displaced in the front-rear direction with respect to the receiver 30, the front-rear dimension of the head rail 12 is shortened.

  Further, the one corner 32a at the uppermost end of the second drum receiver 32 is aligned with the ridge line 14f of the upper holding portion 14, and is therefore located between the front and rear flange portions 12g and 12h of the head rail 12, and It is located at almost the same height as the parts 12g and 12h. With this arrangement, the space between the flange portions 12g and 12h, which usually becomes a dead space, is effectively used, and the height dimension of the head rail 12 is shortened.

  An operating device 48 is provided at the end of the head rail 12. The operation device 48 includes a pulley, a driving force transmission device that transmits the driving force of the pulley to the drive shafts 46 and 47, and an operation chain 50 that is mounted on the pulley. The pulley is rotated by the operation of the operation chain 50, and either one of the drive shafts 46 and 47 can be selectively operated via the drive force transmission device.

  Brakes 52 and 53 and stoppers 54 and 55 are disposed between the plurality of first winding drum assemblies 22 and between the plurality of second winding drum assemblies 24, respectively, and corresponding drive shafts 46, 47. The brakes 52 and 53 decelerate the rotational speeds of the first and second hoisting cords 38 and 40, which will be described later, and the first and second winding drum assemblies 22 and 24 in the unwinding direction, respectively. The rotation of the drive shafts 46 and 47 can be restricted, respectively.

  One end of a first lifting / lowering cord 38 is connected to the first winding drum 26 and one end of a second lifting / lowering cord 40 is connected to the second winding drum 28 so as to be wound and unwound. The other end of 38 passes through the first opening 34 and the first opening 13 e and hangs down to the rear side of the first fabric 16. On the other hand, the other end of the second lifting / lowering cord 40 is located at a position where the position of the axis of the second winding drum 28 is shifted rearward of the head rail 12 from the position of the axis of the first winding drum 26. Since the second opening 36 and the second opening 14e are located directly below the point where the second lifting / lowering cord 40 is separated from the second winding drum 28, the second lifting / lowering cord 40 separated from the second drum portion 28 is naturally vertical. And the second opening 36 and the second opening 14 e are inserted into the rear side of the second fabric 18. At this time, the other ends of the first and second elevating cords 38 and 40 pass through the plurality of cord rings 20 and hang down, and the lowermost code ring 20 includes the first and second elevating cords 38 and 40. A cord holder 44 attached to the end is connected.

  In the roman shade configured as described above, when the operating device 48 is operated to selectively rotate the drive shaft 46, the first winding drum 26 rotates and the first lifting / lowering cord 38 is wound. The first dough 16 can be lifted or lowered by removing or unwinding. Further, when the operating device 48 is operated to selectively rotate the drive shaft 47, the second winding drum 28 rotates to wind or unwind the second lifting / lowering cord 40, and the second dough 18 can be raised and lowered.

  When the second lifting / lowering cord 40 is wound and unwound on the second winding drum 28, the second lifting / lowering cord 40 moves up and down substantially vertically through the space of the second opening 36 and the second opening 14e. Since there is nothing that gives resistance to the second lifting / lowering cord 40 when the opening is inserted, the operation load when operating the second lifting / lowering cord 40 is reduced. Of course, the first lifting / lowering cord 38 also moves up and down substantially vertically through the space of the first opening 34 and the second opening 13e, and gives resistance to the first lifting / lowering cord 38 when inserted through these openings. Therefore, the operation load when operating the first lifting / lowering cord 38 is reduced.

  Since the positions of the second opening 14e and the second opening 36 are on the rear upper side with respect to the cloth attachment portion 12e for the second cloth 18 on the rear wall surface 12b of the head rail 12, the second opening 14e hangs down from the second winding drum 28. 2 The lifting / lowering cord 40 can be easily arranged on the rear side of the second fabric 18 and the attachment work of the second winding drum assembly 24 to the head rail 12 is facilitated. That is, when the first and second winding drum assemblies 22 and 24 are attached to the head rail 12, the fasteners 62 (see FIGS. 1 and 5) are respectively provided from the lower side of the first opening 13e and the second opening 14e. However, since there is nothing obstructing the lower side of the second opening 14e, it is easy to insert the fastener 62 for fixing the second winding drum assembly 24. Can do. Further, since the opening surface of the second opening 14e is inclined from the horizontal plane, the opening area of the second opening 14e for insertion work can be ensured without increasing the front-rear dimension of the head rail 12.
