Description

  The present invention relates to a multiplex shade head rail for suspending a plurality of roman shades so as to be able to move up and down, and particularly to prevent mutual interference and entanglement when roman shades are lifted in a folded state. It is related with the multiplex-type head rail for Roman shades.

  In recent years, in the case of roman shades, interior decorations using double or triple shades with different purposes such as lace, drape, and balance are preferred. Among these, as a head rail having a simple structure for suspending two shades so that they can be raised and lowered, one head rail body is formed in a substantially rectangular cross section, and the internal space is made a space for accommodating the shade lifting device, Shade suspensions are provided on the outer surfaces of the front and rear walls on the indoor side and the window side, and the upper end of the shade is attached to each shade suspension (see, for example, Patent Document 1).

  One of the hook-and-loop fasteners is attached to the above-described shade hanging portion, and the other of the hook-and-loop fasteners is also sewn to the upper end portion of the shade, but the two shades are arranged with the surface facing the indoor side. On the other hand, the two shade suspensions of the head rail body are provided in opposite directions, so that one shade has the other surface fastener on the front surface and the other shade has the other surface fastener on the back surface. There is a hassle of having to sew.

  As a countermeasure for this, the other side of the surface fastener is sewn on both sides of the upper end portion of each shade, thereby eliminating the inconvenience of having to sew the surface fastener, which was a drawback of Patent Document 1, and any shade. A head rail has been proposed in which the external appearance can be easily changed by detachably attaching to the front or rear wall of the head rail body (see, for example, Patent Document 2).

  FIG. 8 shows a state in which two shades are drawn up from FIGS. The two shades 4 and 5 having the upper end portions 4a and 5a attached to the shade suspension portions 2 and 3 of the front wall 1a and the rear wall 1b of the head rail body 1 have their palms facing directly below the elevating cords 5 and 6. Since the hoisting parts 4b and 5b interfere with each other because the hoisting parts 4b and 5b interfere with each other, one of the hoisting parts 4b and 5b wraps around the other. If the raising / lowering cord connected to this side is hindered by lowering the side-raised portion, the raising / lowering operation may not be performed.

Therefore, a falling wall is suspended from the lower end of the rear wall of the head rail body, and a shade hanging portion is provided on the indoor side surface of the falling wall (for example, claims 1, 2, Paragraph No. 0008, Paragraph Nos. 0013 to 0015, Paragraph No. 0021, and FIG. 3 to FIG. 5), the front wall of the head rail body is separated from the head rail body, and the front end of the upper wall extends in the indoor and outdoor directions. There has been proposed a head rail for a roman shade that is pivotally supported and provided with a shade hanging portion on the outer surface, which is the indoor side surface of the front wall, and a shade hanging portion on the inner surface of the rear wall ( Similarly, refer to paragraph Nos. 0023 to 0025 and FIGS. 6 to 8 of the specification of Patent Document 3). With such a configuration, when both shades are lifted up and interfere with each other, the front wall is placed indoors. Shade moving to be suspended in this by escaping the indoor side, so that ease of interference.
Japanese Patent No. 3379934 JP 2003-169746 A JP 2004-229837 A

  However, in the former structure of Patent Document 3, since the shade hanging portions at the front and rear portions are offset in the vertical direction, the attachment and detachment of the two shade hanging portions in the indoor / outdoor direction is slightly facilitated. Since the dimensions are not different from those of Patent Documents 1 and 2, it cannot be said that the above-described interference at the time of tapping is sufficiently avoided.

On the other hand, in the latter structure of Patent Document 3, the front wall of the head rail swings indoors, so that it does not look good. In addition, the front wall of the head rail also swings in the internal space, and the upper end of the shade on the window side is attached to the inner surface of the rear wall, so the shade lifting device cannot be accommodated in the internal space of the head rail. The head rail for the roman shade is limited to a cord type in which the shade is raised and lowered with a cord, and a chain type using a winding drum cannot be adopted.
That is, the latter of Patent Document 3 is limited to the cord type, and has a structure in which downward rail portions are respectively suspended at the lower ends of the front wall and the rear wall, and further a cord insertion ring is attached to these rail portions. It has an overhanging shape, and the package is inferior in transportability.

Furthermore, although the head rail for the roman shade is cut according to the site size, the falling wall protrudes from the head rail main body as in Patent Document 3, so that the cut surface at the site causes chatter and the like. It has been difficult to cut out to an accurate dimension such as a slanting.
Therefore, the present invention is a multiplex shade head rail for suspending a plurality of shades so as to be able to be lifted and lowered. An object of the present invention is to provide a multiplex shade head rail for a roman shade that can be cut easily and accurately.

  In order to solve the above-mentioned problems, the present invention has a plurality of head rail bodies that accommodate shade lifting devices arranged in parallel in the indoor and outdoor directions, and is suspended from the front wall of the head rail body disposed at least on the innermost room side. In a roman shade head rail having a lowering portion, the swing rail portion swings in the indoor / outdoor direction on the front wall side of the bottom wall of the other head rail body excluding the head rail body on the innermost room side or on the lower end of the front wall. It is characterized in that it can be suspended and provided with a shade hanging part on the swing rail part.

  The swing rail portion of the present invention is allowed to swing from the vertical position to the rear wall side of the other head rail main body to a position where it overlaps with the lower surface of the bottom wall of the other head rail main body. The swing of the other head rail toward the front wall can be restricted.

In the multiplex shade head rail for the Roman shade according to the present invention, a chain type is used in which a space space for accommodating a shade lifting device such as a winding drum is secured inside each head rail body. When there are three or more head rail bodies, the swing rail portion can be provided on each of the head rail bodies other than the head rail body on the innermost room side.
The hanging position of the swing rail portion can be selected from either the front wall of the bottom wall of another head rail body or the lower end of the front wall of another head rail body. As a result, when the raised parts interfere with each other, a sufficient swinging space for the swing rail portion can be secured on the rear wall side of the other head rail body, and the swing rail portion can be used as a load form during transport to the other head rail. When superposed on the bottom wall of the rail body, the swing rail portion does not have to protrude outside the other head rail body.

  It is suspended from the shade hanging part located on the front wall of the head rail body on the innermost side and the shade hanging part located on the front wall side of the bottom wall of the other head rail body or the swing rail part on the lower end of the front wall. When the two shades are lifted upward, the raised portions interfere with each other as in the conventional case, but the shade located on the window side pressed by the raised portion of the shade located indoors is raised. Since the part swings the swing rail part to the window side (the rear wall side of the head rail body that suspends the swing rail part) and the raised part of the indoor shade is retracted to the window side, interference between the two raised parts is eased.

  Further, by restricting the swing rail portion so as not to swing from the vertical position to the front wall side of the other head rail, interference between the raised portions can be more reliably reduced. Furthermore, by allowing swinging of the swing rail part from the vertical position to the rear wall side of the other head rail body up to the position where it overlaps the lower surface of the bottom wall of the other head rail body, the package form becomes compact. . When the on-site cutting operation is performed in a state where the swing rail portion is in close contact with the bottom wall of the head rail body, chatter noise is unlikely to occur and the cutting is easy.

  According to the multi-type head rail for the roman shade of the present invention, the chain type that secures a space for accommodating the shade lifting device such as a winding drum inside the head rail body, and the interference between the raised portions of the shade is adopted. Can be compensated as much as possible to compensate for the smooth lifting operation. Further, the swing of the swing rail portion for softening the interference of the raised portion is performed on the back side covered with the shade on the innermost room side and is not touched directly to human eyes, so it is excellent in appearance.

  Further, by restricting the swing rail portion so as not to swing from the vertical position to the front wall side of the other head rail, interference between the raised portions can be more reliably reduced. Furthermore, by allowing swinging of the swing rail part from the vertical position to the rear wall side of the other head rail body up to the position where it overlaps the lower surface of the bottom wall of the other head rail body, the packing form becomes compact. Therefore, the conveyance efficiency can be improved. In addition, since the chatter noise is less likely to occur when the on-site cutting is performed with the swing rail portion in close contact with the bottom wall of the head rail body, highly accurate cutting can be performed easily in a short time.
