Hereinafter, the curtain rail cap mounting device according to the embodiment will be described with reference to the drawings. As an example, the curtain shown in FIG. 1 shows a single-sided curtain in which the curtain fabric as a shielding material is pulled out from left to right (in the direction of arrow D1) and folded from right to left (in the direction of counter arrow D1). ..

[First Embodiment]
The curtain rail 1 extending in one direction includes a rail main body 2 which is a long profile, and

cap attachment devices

3a and 3b fixed to each end of the rail main body 2. The cap mounting device on the left side is 3a, and the cap mounting device on the right side is 3b.

The rail body 2 accommodates a large number of runners 4 and supports them in a movable manner. A hanging ring 5 is attached to the runner 4, and the upper edges of the curtain fabric 6 are suspended and supported at equal intervals. One end of the upper edge of the curtain fabric 6 (the upper edge on the upstream side with respect to the arrow D1 direction) is suspended and supported by a cap attachment device 3a attached to one end in the same direction of the rail body 2. .. Further, as shown in FIG. 2, the other end of the upper edge of the curtain fabric 6 (the upper edge end on the downstream side with respect to the arrow D1 direction) is suspended from the end runner 7 located at the head when the curtain is closed. It is supported. A cap mounting device 3b is attached to the other end of the rail body 2 on the downstream side in the direction of arrow D1. Then, when the end runner 7 is moved to the cap mounting device 3b at the other end of the rail body 2 in the direction of the arrow D1 which is the closing direction and the end runner 7 is attracted to the cap mounting device 3b, the curtain fabric 6 is released. It is held in the pulled out state.

As shown in FIG. 3, the rail main body 2 is a long member and accommodates a plurality of runners 4 and end runners 7 so as to be movable in the longitudinal direction. The rail body 2 has a substantially rectangular frame shape in a cross-sectional view orthogonal to the longitudinal direction. The rail body 2 includes a front wall 11, a rear wall 12, a top plate 13, and a pair of front and rear rail pieces 14.

The front wall 11 is an arc-shaped wall that gently projects forward. The front wall 11 includes an upper end portion 11a. The upper end portion 11a is located above the top plate 13. The upper end portion 11a projects diagonally upward from the upper end of the front wall 11 so as to cover the front of the top plate 13 from above. The height of the front wall 11 and the height of the rear wall 12 are such that the front wall 11 is higher by the amount of the upper end portion 11a, and the upper end portion 11a is the highest position in the rail body 2. The rear wall 12 has a flat plate shape extending along the longitudinal direction.

The top plate 13 constitutes a top surface portion and includes a rear end portion 13a. The rear end portion 13a is the upper end of the rear wall 12 and projects rearward from the rear wall 12. The top plate 13 is provided with a recess 13b substantially in the center in the front-rear direction. The recessed portion 13b protrudes from the top plate 13 side toward the inside of the rail body 2 and extends in the longitudinal direction.

The pair of rail pieces 14 in the front and rear are plate-shaped bottom pieces extending in the longitudinal direction. The pair of front and rear rail pieces 14 form a rail groove 14a extending in the longitudinal direction. The runner 4 and the end runner 7 are supported by an inner surface which is an upper surface of each rail piece 14, and are inserted vertically through the rail groove 14a. The portion of the runner 4 that suspends the curtain fabric 6 is exposed. The rail body 2 configured as described above has an asymmetrical shape with respect to an axis 19 in which each end in the longitudinal direction passes through the center in the width direction, which is also the front-rear direction of the rail body 2, and extends vertically in the side view. .. For example, the rail groove 14a is positioned slightly forward with respect to the shaft 19.

The

cap mounting devices

3a and 3b provided at the left and right ends of the rail body 2 are mounting devices for fixing the cap 21 fixed to each end of the rail body 2 to the end of the rail body 2 at the same time. It also functions as an end holding device for holding the upper edge edge of the curtain fabric 6. Since the

cap mounting devices

3a and 3b provided at the left and right ends of the rail body 2 have the same configuration, the cap mounting devices 3b provided at the other end of the rail body 2 are examples in FIGS. 2 to 7. Explain to.

As shown in FIG. 3, the cap mounting device 3b includes a cap 21 attached to the other end of the rail body 2 and a fixing member 22 for fixing the cap 21 to the other end of the rail body 2. .. Further, the cap mounting device 3b includes a receiving metal fitting 23 that receives the end runner 7.

As shown in FIGS. 3 and 4, the cap 21 has a lid-like shape that covers the outer peripheral surface of the end portion of the rail body 2, and has an end wall 21a and a peripheral wall 21b that rises and is formed around the end wall 21a. And have. The cap 21 has a configuration in which any end of the rail body 2 can be attached. The peripheral wall 21b is a wall that covers the end portion of the rail body 2 from the outside. An insertion portion 21c into which the other end of the rail body 2 is inserted is configured in the inner space portion surrounded by the end wall 21a and the peripheral wall 21b. A notch 24 is formed in the upper portion of the peripheral wall 21b. When the end portion of the rail body 2 is fitted to the insertion portion 21c, the tip end portion of the upper end portion 11a is located at the notch portion 24. Specifically, the front edge portion of the notch portion 24 is located at the upper end portion 11a of the front side wall surface of the peripheral wall 21b. The upper portion of the cap 21 is aligned with the upper end portion 11a of the rail main body 2, and the ceiling 40 can be attached to the ceiling without forming a gap with the upper end portion 11a. The upper portion of the cap 21 may be located slightly lower than the upper end portion 11a of the rail main body 2 because it does not interfere with the ceiling attachment.

A fixing piece 26 for fixing the cap 21 to the end of the rail main body 2 projects from the inner surface of the end wall 21a. The fixing piece 26 has an H-shape, and includes a pair of first walls 26a extending in the vertical direction and a second wall 26b extending in the front-rear direction connecting the pair of first walls 26a. The upper ends of the pair of first walls 26a abut against the inner surface of the top plate 13 of the rail body 2 to position the cap 21 with respect to the rail body 2. The lower surface of the second wall 26b is provided with an engaging recess 26c to which the circular annular wall 32 forming the fixing hole 32a of the receiving metal fitting 23 is engaged.

Further, an annular wall 26e is erected on the upper surface of the second wall 26b, and an insertion hole 26d is formed inside the annular wall 26e. The insertion hole 26d has an elongated hole shape with a major axis in the front-rear direction. The cap 21 is removable from both one end and the other end of the rail body 2, but since the rail body 2 has an upper end 11a and the like, each end in the longitudinal direction is formed. In side view, it has an asymmetrical shape with respect to the axis 19 passing through the center and extending vertically. Therefore, when the cap 21 is attached to one end and the other end, the front and rear are reversed, and the position of the fixing hole 32a of the receiving metal fitting 23 with respect to the cap 21 is slightly displaced in the front and rear direction. .. In order to absorb this deviation, the insertion hole 26d has an elongated hole shape with a major axis in the front-rear direction. As a result, the fixing position by the fixing member 22 becomes a position biased to one end of the insertion hole 26d when the cap 21 is fixed to one end of the rail body 2, and is inserted when fixed to the other end of the rail body 2. The position is biased toward the other end of the hole 26d.

The cap 21 further includes a hanging lower portion 27 from which the upper edge end of the curtain fabric 6 is suspended. The hanging lower portion 27 is composed of projecting pieces protruding downward from the peripheral wall 21b, and is integrally molded. The hanging lower portion 27 functions as a covering portion for covering the receiving piece 34 and as a supporting portion for supporting the receiving piece 34. The hanging lower portion 27 is located parallel to the receiving piece 34. Like the receiving piece 34, it is located on the end side of the rail body 2 with respect to the fixed position where the cap 21 is fixed by the fixing member 22 via the receiving metal fitting 23. The hanging lower portion 27 is provided with a hanging hole 27a. The hanging hole 27a is formed of a long hole having a long axis in the front-rear direction. In the cap mounting device 3a provided at one end of the rail body 2, the runner 4 located at the end opposite to the end runner 7 is engaged with the hanging hole 27a via the hanging ring 5 or the like. .. Further, the hanging lower portion 27 is provided with a support recess 27b on the inner surface. By engaging the receiving piece 34 of the receiving metal fitting 23 with the supporting recess 27b, the receiving piece 34 is supported from the outside, that is, from the end side of the rail body 2. A support wall 27c having a height continuous with the support surface of the support recess 27b is also erected on the inner surface of the end wall 21a, and the top surface of the support wall 27c supports the receiving piece 34. Since the receiving piece 34 is supported by the support recess 27b, it is hidden by the support peripheral wall 27d constituting the support recess 27b, and the design can be improved.

Here, the peripheral wall 21b as the first peripheral wall has a width W1, and the support peripheral wall 27d as the second peripheral wall has a width W2, and the relationship between the width W1 and the width W2 is W1> W2. It has become. That is, the peripheral wall 21b and the supporting peripheral wall 27d have the same height. Therefore, the peripheral wall 21b can have a depth sufficient to firmly fit the end portion of the rail body 2. On the other hand, the support peripheral wall 27d can make the hanging lower portion 27 thinner. For example, by reducing the thickness of the hanging lower portion 27, the hanging ring 5 engaged with the hanging hole 27a can also be reduced in size and diameter. Further, the tip of the peripheral wall 21b and the tip of the support peripheral wall 27d are flush with each other and have the same height. Therefore, when the curtain rail 1 is viewed from the front, the edge portion that is the boundary with the rail body 2 from the upper end of the cap 21 to the lower end of the hanging lower portion 27 becomes straight, and the design is improved.

Further, the inner surface of the end wall 21a is provided with a protrusion 28 between the fixed piece 26 in the front-rear direction and the peripheral wall 21b. Two protrusions 28 are provided, and one protrusion 28 is engaged with one of the front wall 11 and the rear wall 12 of the rail body 2 to suppress deformation of the wall and the other protrusion 28. By engaging with the other wall, 28 suppresses the deformation of the wall.

As shown in FIG. 5, the receiving metal fitting 23 is formed by punching and bending a material that is magnetically attracted by a magnet incorporated in the end runner 7, for example, a metal plate. The receiving metal fitting 23 includes a base portion 31. The base portion 31 is a portion fixed to the fixing piece 26 by the fixing member 22. The base 31 is provided with a circular annular wall 32 on the upper surface. The circular annular wall 32 has a fixing hole 32a formed on its inner peripheral surface, and the fixing hole 32a is formed with a screw groove into which the fixing member 22 is screwed. The circular annular wall 32 is engaged with the engaging recess 26c of the cap 21. The fixing member 22 screwed into the fixing hole 32a is a screw and includes a screw portion 22a as a fixing portion and a head portion 22b located at the base end of the screw portion 22a.

A pair of pressure contact pieces 33 are provided on both side edges of the base portion 31 in the front-rear direction. The pair of pressure contact pieces 33 are pieces that are bent substantially perpendicular to the base portion 31, and the distance between them is set to be slightly wider than the width of the rail groove 14a. The tip ends of the pair of pressure contact pieces 33 are pressure-welded to the inner surface of the pair of rail pieces 14 forming the rail groove 14a. The base portion 31 is provided with a notch recess 31a for cutting up the receiving piece 34. The end portion of the pair of pressure contact pieces 33 on the notch recess 31a side is abutted against the inner surface of the end wall 21a of the cap 21.

Further, a receiving piece 34 is provided on one side edge portion orthogonal to the pair of pressure contact pieces 33 of the base portion 31. The receiving piece 34 is bent downward and faces the end runner 7. The receiving piece 34 is provided with a slit 34a cut upward with the tip end as an opening end. When the receiving metal fitting 23 is attached to the cap 21, the slit 34a intersects the hanging hole 27a formed of a long hole having a long axis in the front-rear direction, and is located at the end opposite to the end runner 7. The runner 4 constitutes an insertion portion to which the hanging ring 5 and the like are engaged.

The receiving piece 34 is provided with a stepped portion 34b at its root. The step portion 34b suppresses deformation of the return metal fitting 51 when the return metal fitting 51 described later is attached. Further, one side edge portion orthogonal to the pair of pressure contact pieces 33 of the base portion 31 is provided with a deformation suppressing piece 35 that suppresses deformation of the return metal fitting 51. The height of the deformation suppressing piece 35 is the same as the stepped surface of the stepped portion 34b. The step portion 34b and the deformation suppressing piece 35 prevent the return metal fitting 51 from being deformed too much when the return metal fitting 51 comes into contact with the return metal fitting 51. The return metal fitting 51 is attached to the cap attachment device 3a side provided at one end of the rail body 2.

Next, a method of fixing the cap 21 to the other end of the rail body 2 will be described. As shown in FIG. 6, the cap 21 is engaged with the circular annular wall 32 forming the fixing hole 32a of the receiving metal fitting 23 with the engaging recess 26c of the fixing piece 26, and the receiving piece 34 is fitted with the supporting recess 27b. Combined by being fitted. Further, the screw portion 22a of the fixing member 22 is loosely screwed into the fixing hole 32a so as not to fall.

In this state, the other end of the rail body 2 is inserted into the insertion portion 21c of the cap 21 by inserting the receiving metal fitting 23 into the other end of the rail body 2. At this time, the front wall 11 of the rail body 2 is located between the front projection 28 and the front peripheral wall 21b, and the rear wall 12 is located on the center side of the end wall 21a with respect to the rear projection 28. Will be done. Then, the end surface of the other end of the rail body 2 is abutted against the inner surface of the end wall 21a. Further, the fixing member 22 that greatly protrudes downward from the fixing hole 32a of the receiving metal fitting 23 enters the rail groove 14a along the longitudinal direction.

When the cap 21 is temporarily fixed to the other end of the rail body 2 in this way, the fixing member 22 that greatly protrudes downward from the rail groove 14a is then tightened. Then, the tip of the screw portion 22a is pressed against the recessed portion 13b of the top plate 13 in the rail body 2. At this time, the receiving metal fitting 23 is screwed downward as the fixing member 22 is tightened, and the tip portions of the pair of pressure contact pieces 33 are pressure-welded to the inner surfaces of the pair of rail pieces 14 constituting the rail groove 14a. Will be done. As a result, in the cap 21, the tip of the screw portion 22a of the fixing member 22 is pressed against the end of the rail body 2 with the recessed portion 13b, and the pair of pressure contact pieces 33 are pressed against the inner surface of the rail piece 14. By doing so, it is fixed to the end of the rail body 2. The head portion 22b of the fixing member 22 enters the inside of the rail body 2 through the rail groove 14a at a position on the center side of the rail body 2 with respect to the peripheral wall 21b of the cap 21 and the receiving piece 34, and is difficult to see from the outside. Become. That is, the head 22b is located above the position L1 of the rail piece 14 and at the invisible position L2, which is the internal position of the rail body 2. As a result, the head 22b becomes invisible even when viewed from the front. Further, the position L1 of the rail piece 14 is a traveling surface on which the runner travels. Further, the position L1 of the rail piece 14 is the lower end of the rail body 2.

At this time, the top plate 13 of the rail body 2 is subjected to a force to push it upward, and a pair of pressure contact pieces 33 is applied to a force to push the rail piece 14 downward, so that the rail body 2 tries to be deformed. However, the rail body 2 is suppressed from being deformed because each of the front wall 11 and the rear wall 12 is in contact with the protrusion 28. Since the upper portion of the cap 21 is aligned with the upper end portion 11a of the rail body 2, the ceiling 40 and the upper end portion 11a are attached to the ceiling 40 via a bracket arranged on the top plate 13. It is possible to prevent a gap from being formed between the two. Further, the curtain rail 1 can be directly attached to the wall surface via the bracket.

FIG. 8 shows a state in which the curtain rail 1 is attached to the ceiling. The rail body 2 is provided with a hole 13c at the position of the recessed portion 13b of the top plate 13. The position of the hole 13c is directly above the rail groove 14a. Then, the fixing screw 15 is passed through the hole 13c from the inside of the rail body 2 and tightened to the ceiling 40. The rail body 2 is fixed to the ceiling 40 by pressing the seating surface of the screw head of the fixing screw 15 against the inner surface of the top plate 13.

Further, FIG. 9 shows another example when the curtain rail 1 is mounted on the ceiling. In FIG. 9, the spacer 16 is used. The spacer 16 is a member arranged on the top plate 13 and has a thickness corresponding to the height from the top plate 13 to the tip of the upper end portion 11a. The end portion 16a facing the upper end portion 11a is formed of an arcuate surface corresponding to the inner shape of the upper end portion 11a. Further, the spacer 16 is provided with a spacer hole 16b at a position corresponding to the hole 13c of the top plate 13. The spacer 16 is arranged on the top plate 13 so that the end portion 16a engages with the inner portion of the upper end portion 11a, and the positions of the holes 13c and the spacer holes 16b are aligned. After that, the fixing screw 15 is passed through the hole 13c and the spacer hole 16b from the inside of the rail body 2 and tightened to the ceiling 40. As a result, the spacer 16 is pressed against the ceiling 40, and the curtain rail 1 is stably attached to the ceiling 40.

In FIG. 1, in the cap mounting device 3a attached to the left end of the rail body 2, one end of the upper edge of the curtain fabric 6 is suspended from the hanging hole 27a of the cap 21 via a hanging ring 5 or the like. .. On the other hand, the other end of the upper edge of the curtain fabric 6 is suspended from the end runner 7. Then, the end runner 7 is moved in the direction of the arrow D1 toward the receiving piece 34 in the cap attachment device 3b, and the end runner 7 magnetically attracts the receiving piece 34 to hold the curtain cloth 6 in a pulled out state. Will be done.

By the way, as shown in FIG. 7A, the end runner 7 traveling toward the receiving piece 34 includes the runner main body 41. The runner body 41 is provided with a pair of rollers 42 at the front and the rear of the upper end portion (see FIG. 3). Each pair of rollers 42 rolls on the inner surface of the rail piece 14 constituting the rail groove 14a. Further, the runner main body 41 is provided with a plurality of hanging holes 43 arranged in the traveling direction at the lower edge portion. The other end of the upper edge of the curtain fabric 6 is hung from the hanging hole 43 via a hanging ring 5 or the like. The number of hanging holes 43 may be one.

The runner main body 41 is provided with a case 44 as an attachment member to the runner main body 41. The runner body 41 includes a mounting portion 45 for mounting the case 44. The case 44 is locked to the mounting portion 45. The case 44 includes an extension portion 46 that extends in the arrow D1 direction, which is the closing direction when attached to the attachment portion 45. The extension portion 46 may be integrated with the case 44, but here it is removable from the case 44. The attachment / detachment mechanism is not particularly limited, but is integrated by, for example, engaging the engaging piece of the extension portion 46 with the engaging hole of the case 44.

The extension portion 46 is configured by incorporating a magnet 47 and a yoke 48 as suction members in a case made of the same material as the case 44. The length 46L of the extension portion 46 from the leading edge portion of the runner main body 41 is about the same as the diameter of the head portion 22b of the fixing member 22. In other words, it is about the same as the length from the end wall 21a of the fixed piece 26 to the tip on the opposite side of the end wall 21a. As a result, the extension portion 46 can straddle the head 22b. That is, the fixing member 22 can straddle the fixed position where the cap 21 is fixed via the metal fitting 23. When the end runner 7 moves in the direction of arrow D1, the tip of the extension 46 magnetically attracts the receiving piece 34 by the magnetic force of the magnet 47. As a result, the extension portion 46 straddles the head portion 22b or the fixed position, and the tip portion thereof comes into contact with the receiving piece 34.

FIG. 7B is a front end runner 49 without an extension 46. For example, the end runner 49 can be realized by removing the extension 46 from the case 44 in the end runner 7. Even if the receiving piece 34 is magnetically attracted by the magnetic force of the magnet 47, the end runner 49 cannot come into contact with the receiving piece 34 because the head portion 22b located in the rail groove 14a becomes an obstacle and cannot come into contact with the receiving piece 34. As the magnet 47 separates from the magnet 47, the magnetic force weakens and it becomes difficult to maintain the closed state in the direction of arrow D1. In this regard, the end runner 7 shown in FIG. 7A includes an extension portion 46, and the tip end portion of the extension portion 46 comes into contact with the receiving piece 34. Therefore, the tip portion of the extension portion 46 is magnetically attracted to the receiving piece 34 in a state of high magnetic force, so that the state of being firmly closed in the arrow D1 direction can be maintained. The magnetic force generating member such as the magnet 47 may be an electromagnet or the like.

The first embodiment as described above can obtain the effects listed as follows.
(1-1) Since the head 22b of the fixing member 22 is located in the rail groove 14a, the head 22b can be obscured from below, and the head 22b can be visually recognized in the rail groove 14a. By being located at the impossible position L2, it can be made invisible even from the front. Therefore, the design around the end of the curtain rail 1 can be improved.

(1-2) The cap 21 can be a common part that can be fitted to one end of the rail body 2 or to the other end. That is, since the rail body 2 has an upper end portion 11a and the like, the rail body 2 has an asymmetrical shape with respect to the shaft 19 (see FIG. 3) in a side view. However, the cap 21 has an elongated hole shape in which the insertion hole 26d has a long axis in the front-rear direction. Therefore, for example, the position of the fixing hole 32a of the receiving metal fitting 23 is positioned at one end and the other end of the rail body 2. Even if the position shifts slightly back and forth depending on the case of mounting, this shift can be absorbed.

(1-3) Since the head 22b is not located on the lower portion of the peripheral wall 21b of the cap 21, the design around the end of the curtain rail 1 can be improved.
(1-4) In the cap 21, the tip of the screw portion 22a of the fixing member 22 is pressed against the end of the rail body 2 to the recessed portion 13b, and the pair of pressure contact pieces 33 are on the inner surface of the rail piece 14. By being pressure-welded, it is securely fixed to the end of the rail body 2.

(1-5) The upper portion of the cap 21 is provided with the notch portion 24 so that the height is equal to or less than the height of the upper end portion 11a of the rail body 2. Therefore, when the ceiling is attached to the ceiling 40 via the bracket, it is possible to prevent a gap from being formed between the ceiling 40 and the upper end portion 11a.

(1-6) The extension portion 46 of the end runner 7 straddles the fixed position of the head 22b or the cap 21, and the tip portion magnetically attracts the receiving piece 34 by the magnetic force of the magnet 47 to attract the receiving piece 34. It is firmly contacted with high magnetic attraction. Therefore, the curtain fabric 6 can be firmly held in the pulled out state.

[Second Embodiment]
At the end of the curtain rail 1, in order to block light leakage and the flow of warm and cold air from the gap between the installation surface 50 such as a wall or window frame and the curtain fabric 6, the gap is preferably small. Therefore, as shown in FIG. 10, one end of the upper edge of the curtain fabric 6 (one end of the upper edge on the side that is not suspended and supported by the end runner 7) is attached to one end of the rail body 2 that is suspended and supported. The cap attachment device 3a is provided with a return metal fitting 51 for suspending one end of the upper edge of the curtain fabric 6 from a position closer to the installation surface 50.

As shown in FIGS. 11A and 11B, the return metal fitting 51 is a suspension that suspends and supports a mounting plate portion 52 for attaching to one end of the rail body 2 and one end of the upper edge of the curtain fabric 6. It is provided with a plate portion 53, and is formed by bending a metal plate. The mounting plate portion 52 is a portion of one end of the rail body 2 that is mounted from the lower side of the rail piece 14 to the rail groove 14a.

The mounting plate portion 52 has an elongated thin plate shape extending from one end of the rail body 2 toward the installation surface 50, and a hanging plate portion 53 is provided at the tip portion. In the mounting plate portion 52, at a position near the end on the side opposite to the hanging plate portion 53 in the longitudinal direction, the screw portion 22a of the fixing member 22 is engaged with the insertion hole 54 into which the threaded portion 22a is inserted and the rail groove 14a. It is provided with a protruding portion 55. The insertion hole 54 has a long hole shape, and the long axis thereof is provided along the longitudinal direction of the mounting plate portion 52 and is located substantially in the center of the width direction where the long axis intersects the longitudinal direction. Has been done. The insertion hole 54 is provided so as to straddle the protrusion 55. Further, the insertion hole 54 has a first wide portion 54a at an end located on the central side of the mounting plate portion 52 in the longitudinal direction with respect to the protruding portion 55, and a narrow portion at the top portion of the protruding portion 55. It is 54b. Further, the insertion hole 54 has a second wide portion 54c at an end opposite to the first wide portion 54a with the protruding portion 55 interposed therebetween.

The first wide portion 54a and the second wide portion 54c are wider than the narrow portion 54b and have a width similar to the diameter of the head 22b of the fixing member 22. The narrow portion 54b is narrower than the first wide portion 54a and the second wide portion 54c. Further, the narrow portion 54b is narrower than the diameter of the head portion 22b and has a width through which the screw portion 22a can be inserted. The narrow portion 54b constitutes a locking portion 54d that locks the head portion 22b. When the mounting plate portion 52 is mounted in the rail groove 14a at the position of the protruding portion 55, the mounting plate portion 52 extends in a direction intersecting the longitudinal direction of the rail body 2 (for example, a direction approaching the installation surface 50).

The hanging plate portion 53 is a piece that is bent so as to hang from one end of the mounting plate portion 52, and is provided with a hanging hole 53a. One end of the upper edge of the curtain cloth 6 is hung from the hanging hole 53a via a hanging ring 5 or the like, and one end of the upper edge of the curtain cloth 6 extends to a position close to the wall or the window frame. become.

Next, the method of attaching the return metal fitting 51 will be described. As shown in FIG. 12, the cap 21 is engaged with the circular annular wall 32 forming the fixing hole 32a of the receiving metal fitting 23 with the engaging recess 26c of the fixing piece 26, and the receiving piece 34 is fitted with the supporting recess 27b. Combined by being fitted. Further, the mounting plate portion 52 of the return fitting 51 is overlapped with the base portion 31 of the receiving metal fitting 23 and the screw portion 22a of the fixing member 22 is inserted into the first wide portion 54a or the second wide portion 54c, and then the base portion 31. Screw loosely so that it does not fall into the fixing hole 32a. In this state, the return metal fitting 51 is in a state of being loosely supported by the screw portion 22a and in a state of rattling between the receiving metal fitting 23 and the head portion 22b and along the insertion hole 54.

Then, the receiving metal fitting 23 is inserted into the inside of one end of the rail body 2, and one end of the rail body 2 is inserted into the insertion portion 21c of the cap 21. Then, the end surface of the rail body 2 is abutted against the inner surface of the end wall 21a. Further, the fixing member 22 that greatly protrudes downward from the fixing hole 32a of the receiving metal fitting 23 is inserted into the rail groove 14a along the longitudinal direction. At this time, the rail piece 14 is inserted between the tip end portion of the pressure contact piece 33 of the receiving metal fitting 23 and the mounting plate portion 52 of the return metal fitting 51 on the outside. Further, the return metal fitting 51 is moved with respect to the rail groove 14a and the fixing member 22. Then, the protruding portion 55 is engaged with the rail groove 14a from the outside of the rail piece 14. As a result, the mounting plate portion 52 is in a state of extending in a direction intersecting the longitudinal direction of the rail main body 2. After that, the fixing member 22 moves the screw portion 22a from the first wide portion 54a or the second wide portion 54c to the narrow portion 54b (see FIG. 11). Then, the fixing member 22 that greatly protrudes downward from the rail groove 14a is tightened. As a result, the head portion 22b is located at the valley portion 55a on the back side of the protruding portion 55 and becomes inconspicuous.

Then, the seating surface of the head 22b is pressed against the locking portion 54d of the mounting plate portion 52, and a part of the head 22b escapes to the first wide portion 54a and the second wide portion 54c. Since the mounting plate portion 52 is interposed in the fixing member 22, the tip portion of the screw portion 22a is not pressed against the recessed portion 13b of the top plate 13 in the rail body 2, but the mounting plate portion 52 and the pressure contact piece 33 The rail piece 14 is sandwiched between the tip portion. As a result, the return metal fitting 51 is fixed to one end of the rail body 2 together with the cap 21.

At this time, the mounting plate portion 52 of the return metal fitting 51 is tightened by the fixing member 22, so that a force that bends inward of the rail body 2 acts. In this regard, as shown in FIG. 13, a step portion 34b of the receiving metal fitting 23 and a deformation suppressing piece 35 are located at the top portion of the protruding portion 55.

The end runner located at the head of the first curtain fabric 91 in the moving direction is the end runner 7 shown in FIG. 7A, and the extension portion 46 is provided in the case 44. The end runner located at the head of the second curtain fabric 92 in the moving direction is the end runner 49 shown in FIG. 7B.

In the state where the first curtain fabric 91 and the second curtain fabric 92 are closed, the end runner 7 of the first curtain fabric 91 and the end runner 49 of the second curtain fabric 92 are magnetically attracted to each other and closed. The state is maintained. Then, the first curtain cloth 91 and the second curtain cloth 92 are opened by separating the end runner 7 and the end runner 49 against the magnetic attraction force.

By the way, the curtain rail 1 may be changed from a double-door curtain to a single-sided curtain as shown in FIG. When the single-sided curtain to be replaced is replaced in the same opening / closing direction as the first curtain fabric 91, the end runners 7 and runners 4 used for the first curtain fabric 91 are used. Further, when the single-opening curtain to be replaced is replaced in the same opening / closing direction as the second curtain fabric 92, the end runners 49 and runners 4 used for the second curtain fabric 92 are used. At this time, the end runner 49 is replaced with the end runner 7, or an extension portion 46 is attached to the end runner 49 to form the end runner 7. As a result, it can be used in the same manner as the one-sided curtain described in the first embodiment.

The curtains described above can be further modified as appropriate as follows. -The

cap attachment devices

3b and 3b may be combined with the end runner 49 shown in FIG. 7 (b) instead of the end runner 7 shown in FIG. 7 (a).

The height of the cap 21 does not have to be the same as that of the tip of the peripheral wall 21b and the tip of the supporting peripheral wall 27d. For example, the heights of the tip of the peripheral wall 21b and the tip of the support peripheral wall 27d may be different to form part of the overall design of the curtain rail 1.

-The support peripheral wall 27d does not have to cover the receiving piece 34. That is, the hanging lower portion 27 does not have to include the support recess 27b. -The cap 21 does not have to have the hanging lower portion 27. In this case, the receiving piece 34 is formed with a circular or elliptical hanging hole having no opening end instead of the slit 34a having the tip end as an opening end and being cut upward.

-As the rail body 2, the upper end portion 11a may be provided on the rear wall 12 side instead of the front wall 11. Further, the rail body 2 may have an asymmetrical shape with respect to an axis that passes through the center in the width direction and extends vertically in the side view. Therefore, the lower end of the front wall 11 or the rear wall 12 may extend so as to project downward.

When the return metal fitting 51 has a strength that makes it difficult for the return metal fitting 51 to be deformed inward of the rail body 2 even when the fixing member 22 is tightened, the base portion 31 of the receiving metal fitting 23 is deformed. It is not necessary to provide the step portion 34b and the deformation suppressing piece 35 that suppress the deformation.

-A return metal fitting having a configuration other than the return metal fitting 51 may be attached to the cap mounting device 3a. For example, a return metal fitting having an L-shape, one piece as a mounting piece and the other piece as a hanging piece can be used. For example, in the examples of FIGS. 14 to 17, since the hook 77 is used, the return metal fitting 51 is unnecessary.

-The return metal fitting 51 does not have to include the protrusion 55 that engages with the rail groove 14a. -The cap 21 does not have to have a notch 24 at the top. In this case, a slight gap is formed between the curtain rail 1 and the ceiling. This gap may be closed by another member, for example, a closing plate.

-The cap 21 is not a common part that can be attached to both one end and the other end of the rail body 2, but may be a separate part for one end and the other end of the rail body 2. In such a case, the insertion hole 26d may have a perfect circular shape instead of an elongated hole shape having a long axis in the front-rear direction. The fact that the cap 21 is a separate part for one end and the other end of the rail body 2 is applicable to the caps of the single rails shown in FIGS. 1 to 13 and the double rails shown in FIGS. 14 to 17. It is also applicable to.

-In the case of a single rail curtain, the cap 21 can be a common part that can be attached to both one end and the other end of the rail body 2. In this case, the receiving piece 34 may have the head portion 22b of the fixing member 22 located on the end side of the rail body 2 with respect to the receiving piece 34.

-In the end runner 7, a magnet or a yoke may be built in the case 44, and only the yoke may be arranged in the extension 46. Further, magnets may be provided on both the case 44 and the extension portion 46. Further, the end runner 49 shown in FIG. 7B may be retrofitted with a magnet or an extension portion of only the yoke. The runner main body 41 and the extension portion 46 may be detachable or non-detachable integral parts.

-The extension portion 46 may be provided so as to project from the runner main body 41 in both directions in the traveling direction.・ The runner equipped with an extension can also be applied to a ring runner running on the outer circumference of the curtain rail and a C-shaped runner.

-The cap attachment device can be applied not only to the cap 21 provided at the end of the curtain rail, but also to the cap attachment device for attaching the cap to the end of various long profiles other than the curtain rail. As an example, it can be applied to a cap attachment device attached to both ends of a frame of a raised curtain.
