  Therefore, in the configuration described in Patent Document 1, the curtain rail is lowered, so that when the curtain is removed from the curtain rail, work can be performed at a low position, but the curtain is removed from or attached to the curtain rail. The attachment / detachment work itself is not different from the conventional work, and there is a problem that the attachment / detachment work is troublesome.

  That is, when removing the curtain together with the runner that is slidably housed in the curtain rail and suspends the curtain, it is necessary to slide each runner to the end of the curtain rail and take it out from the end, and then attach the curtain In this case, it is necessary to insert each runner into the small rail space from the end of the curtain rail, which is troublesome. In this case, if a work place cannot be secured at the end of the curtain rail, the work becomes difficult.

  Alternatively, when the curtains are removed from the runners instead of removing the runners from the curtain rails, the work is troublesome because the runners are restrained in the rail space of the curtain rails.

  This invention is made | formed in view of this subject, and it aims at providing the movable rail which can perform the attachment or detachment operation | work of the shielding material with respect to a rail easily.

  In order to achieve the above-described object, a movable rail for a shielding material according to the first aspect of the present invention includes a first rail constituent member and a second rail constituent member, and the first rail constituent member and the second rail configuration. A rail space is formed by combining the members in close proximity to each other, and in the rail space, a shielding material supporting member that supports the shielding material can be accommodated so as not to fall off, while the first rail component member and By the relative movement in the separating direction with respect to the second rail component member, the rail space is opened and the shielding material support member is detachable.

  According to a second aspect of the present invention, in the first aspect, the first rail constituent member is fixed, and the second rail constituent member is movable up and down relative to the first rail constituent member. .

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a lifting / lowering means for lifting / lowering the second rail component member is provided, and the lifting / lowering means includes: a head box fixed to a fixed surface; A hoisting string that hangs down so as to be able to move up and down, and an operation unit that performs an elevating operation of the hoisting string. It is connected, The 2nd rail structural member can be raised / lowered with respect to a 1st rail structural member by operation of an operation part, It is characterized by the above-mentioned.

  According to a fourth aspect of the present invention, a pandagraph mechanism is connected to the second rail constituent member according to any one of the first to third aspects, and the pandagraph mechanism expands and contracts with the movement of the second rail constituent member. And the attitude | position of a 2nd rail structural member is maintained, It is characterized by the above-mentioned.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall front view of a movable rail according to a first embodiment of the present invention, FIG. 2 is an overall front view showing a state in the middle of movement of the movable rail, FIG. 3 is an enlarged view thereof, and FIG. It is an enlarged view which shows a back state.

  The movable rail 10 of this example is a curtain rail composed of an upper rail constituent member 12 as a first rail constituent member and a lower rail constituent member 14 as a second rail constituent member which are separate members. Yes. The upper rail constituent member 12 and the lower rail constituent member 14 can be moved relative to each other, and the movable rail 10 is provided with lifting means 16 for operating and driving the relative movement of both the members 12 and 14. It has been.

  As shown in FIG. 4 and the like, the upper rail component member 12 has a substantially U-shape having a rail upper surface wall 12a, a rail front wall 12b, and a rail rear wall 12c. 14 has a substantially U-shaped shape including a rail bottom wall 14a, a rail front wall 14b, and a rail back wall 14c. The rail front wall 12b and the rail front wall 14b are respectively a rail back wall 12c and a rail back wall 12c. It is shorter than the rail back wall 14c. The upper rail component member 12 and the lower rail component member 14 are combined with each other to form a rail space R extending in one longitudinal direction, and a gap is formed between the rail front walls 12b and 14b of both the members 12 and 14. Thus, a rail opening O that communicates the rail space R with the outside is configured.

  In the rail space R, a plurality of runners 30 as shielding material support members can be slidably accommodated along the rail direction. As shown in FIG. 6, the runner 30 includes a wheel 30 a that can travel in the rail space R, and a hook 30 b that protrudes forward from the wheel 30 a and sandwiches the curtain fabric 32 that is a shielding material. In a state where the runner 30 is housed in the rail space R, the hook 30b extends through the rail opening O to the outside, and the curtain fabric 32 can be suspended from the hook 30b protruding to the outside.

  The lifting / lowering means 16 is connected to a head box 18 fixed to a fixed surface such as a window frame or a ceiling, a lifting / lowering string 20 that can be lifted / lowered from the head box 18, and an upper end of the lifting / lowering string 20 that can be wound and unwound. A plurality of winding drums 22 (only the winding drum 22 at the end is shown in FIG. 3), a rotating shaft 24 penetrating each winding drum 22 so as to be integrally rotatable, and one end of the rotating shaft 24. A clutch 26, and a pulley connected to the clutch 26 and an operation portion 28 including an operation cord wound around the pulley. The upper rail component 12 may be fixed to the head box 18 or may be configured as an integral part of the head box 18. The lower end of the lifting / lowering string 20 is connected to the lower rail constituting member 14. The clutch 26 has a function of preventing the rotation from the rotation shaft 24 based on the weight of the lower rail constituent member 14 and the like while transmitting the operation force from the operation unit 28 to the rotation shaft 24.

  In the movable rail 10 configured as described above, the lifting / lowering string 20 is wound to the maximum extent by the winding drum 22 during normal use, and the upper rail component member 12 and the lower rail component member 14 are The rail space R is formed in the state where they are in close proximity to each other and combined. In this combined state, the upper rail component member 12 supports the runner 30 from above, the lower rail component member 14 supports the runner 30 from below, and the wheel 30a of the runner 30 cannot pass through the rail opening O. For this reason, the runner 30 cannot be removed from the rail front.

  Thus, the movable rail 10 supports the fabric 32 via the runner 30 accommodated in the rail space R, and the fabric 32 can perform any operation such as opening and closing as a curtain.

  Next, when the fabric 32 is removed from the movable rail 10 for exchanging or washing the fabric 32, the operation unit 28 is operated to rotate the rotary shaft 24 and the winding drum 22 in the lifting string unwinding direction. Then, the lifting string 20 is unwound. As a result, the lower rail constituting member 14 is lowered as shown in FIGS. At this time, the runner 30 is placed on the rail bottom wall 14a of the lower rail constituting member 14, and is supported from below by this, and is also supported from the front and rear by the other rail front wall 14b and rail back wall 14c. Therefore, the lower rail component 14 is lowered together with the lower rail component 14 without dropping.

  When the lower rail component 14 is lowered to an appropriate height, the operation of the operation unit 28 is stopped, and the lowering of the lifting / lowering string 20 is stopped by the clutch 26. As shown in FIG. 5, in this state, the rail space is no longer formed and the upper part is open, so that the runner 30 can be easily removed from the rail front.

  After the runner 30 is removed together with the fabric 32, appropriate processing is performed. For example, when washing the fabric 32, it is even more convenient if the runner 30 can be washed together. However, even when the fabric 32 is removed from the runner 30, the runner 30 is not restrained by the rail space, so that the removal operation can be easily performed.

  Moreover, the dough 32 can be more easily removed from the runner 30 by connecting the dough 32 and the runner 30 to a modified example as shown in FIG. In this modification, the cloth 32 and the runner 30 are connected via a plate 34 fixed to the upper end of the cloth 32, and the plate 34 is fixed to the cloth 32 by means of sewing or the like at appropriate places. The plate 34 is formed with a large-diameter hole 34a and a fine hole 34b communicating with the large-diameter hole 34a at the top. The runner 30 has a small-diameter portion 30d and a large-diameter portion 30e formed at the end of a shaft portion 30c that extends forward from the central axis of the wheel 30a. The large diameter part 30e and the small diameter part 30d can pass through the large diameter hole 34a, whereas the large diameter part 30e cannot pass through the pore 34b, and only the small diameter part 30d can pass through the pore 34b. ing. Accordingly, when removing the fabric 32 from the runner 30, the large diameter portion 30e moves toward the large diameter hole 34a and passes through by moving the fabric 32 upward with respect to the runner 30. Thus, the connection between the two can be easily released. On the other hand, in order to attach the fabric 32 to the runner 30, the large diameter portion 30 e of the runner 30 is passed through the large diameter hole 34 a of the plate 34, and then the fabric 32 is moved downward so that the large diameter portion 30 e becomes the pore 34 b. By moving to the direction of making it impossible to pass through, both are simply connected, and the fabric 32 is suspended from the runner 30.

  When the fabric 32 connected to the runner 30 is attached to the movable rail 10, after the runner 30 is placed on the lower rail component 14, the operation unit 28 is operated to move the rotary shaft 24 and the take-up drum 22 up and down. The lower rail component 14 and the upper rail component 12 are automatically combined by rotating the string in the string winding direction, winding the lifting string 20 to the maximum extent, and the runner 30 has the rail space R. Restrained by

  Thus, the runner 30 can be easily attached to and detached from the movable rail 10. The runner 30 can be attached and detached at an appropriate position according to the height of the operator by lowering the lower rail component member 14. Further, the runner 30 can be detached from the lower rail component member 14 from the front side or Since it only has to be placed, the work is easy and no special work space is required. Therefore, it is also possible to arrange the end of the movable rail 10 on the wall surface or pillar.

  7 and 8 are overall front views showing the second embodiment of the present invention, FIG. 7 shows a state in the middle of movement, and FIG. 8 shows a state after the movement. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this example, in addition to the configuration of the first embodiment, a pantograph mechanism 40 that is an expandable / contractible member is provided between the head box 18 and the lower rail component member 14. The rail constituent member 14 is allowed to move up and down while being restricted to maintain its posture.

  This prevents the lower rail component member 14 from being inclined during the up-and-down movement, and prevents the runner 30 from falling from the lower rail component member 14 during the up-and-down movement. The pantograph mechanism 40 may be provided between the lower rail constituent member 14 and the upper rail constituent member 12 or an arbitrary stationary member instead of the upper rail constituent member 12 instead of the head box 18.

  9 to 11 are partial views showing a third embodiment of the present invention. The same members as those of the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The movable rail 10 of this example is a head rail such as a roman shade, and is a rail for supporting the roman shade fabric 44 as a shielding material.

  For this reason, the code guide 52 is attached to the lower surface of the lower rail constituent member 14 at a predetermined interval in the rail direction, and the stopper 54 is attached to one end side thereof in alignment with the code guide 52. A plurality of lifting / lowering cords 56 are guided by the code guide 52, and one end of each lifting / lowering cord 56 passes through the cord guide 52, hangs down through the stopper 54, and is connected to a knob (not shown). Further, the other ends of the lifting / lowering cords 56 are suspended from the corresponding code guides 52, and after passing through a cord ring 44 a attached to the back surface of the fabric 44 at a predetermined interval in the vertical direction, Connected.

  A shielding material fixing member 46 as a shielding material support member is attached to the upper end of the fabric 44, and the shielding material fixing member 46 is a rail space formed by the upper rail constituent member 12 and the lower rail constituent member 14. The constricted part 46a can be inserted through the rail opening O.

  Also in the movable rail 10 configured as described above, the lifting / lowering string 20 is wound up to the maximum extent by the winding drum 22 during normal use, and the upper rail constituting member 12 and the lower rail constituting member 14 are The rail space R is formed in the state where they are in close proximity to each other and combined. In this combined state, the upper rail constituent member 12 supports the shielding member fixing member 46 from above, the lower rail constituent member 14 supports the shielding member fixing member 46 from below, and the main body of the shielding member fixing member 46 is Since the rail opening O cannot be removed, the shielding member fixing member 46 cannot be removed from the rail front.

  Thus, the movable rail 10 supports the fabric 44 via the shielding member fixing member 46 accommodated in the rail space R, and the fabric 44 can perform any operation such as raising and lowering as a roman shade. That is, by pulling one end side of the lifting / lowering cord 56 to release the stopper 54, the movement of the lifting / lowering cord 56 is allowed. Therefore, by further pulling the lifting / lowering cord 56, the fabric 44 is lifted from the lower end thereof, or lifted / lowered By releasing the tension of the cord 56, the dough 44 descends from its lower end. When the one end side of the lifting / lowering cord 56 is pulled again, the movement of the lifting / lowering cord 56 is prohibited by the action of the stopper 54 and the dough 44 stops.

  Further, when removing the fabric 44, the lower rail component member 14 can be lowered and removed from the rail front surface in the same procedure as in the first embodiment. The cloth 44 is removed together with the shielding material fixing member 46. At this time, the lower end of the lifting / lowering cord 56 is preferably disconnected from the cloth 44 in advance.

  Also in this embodiment, the same effect as that of the first embodiment can be obtained, and the pantograph mechanism 40 of the second embodiment can be combined with this embodiment.

  In the illustrated example, the upper rail constituent member 12 and the lower rail constituent member 14 are common parts having the same shape, and this makes it possible to share parts, which is advantageous in terms of cost. However, the present invention is not limited to this, and the upper rail constituent member 12 and the lower rail constituent member 14 may have different shapes.

  Further, in the above example, the lower rail component 14 is raised and lowered, so that the rail that is normally at a high position can be moved to a height position suitable for the shielding material attaching / detaching work, but this is not limited thereto. Instead, the upper rail constituent member 12 and the lower rail constituent member 14 may be moved relative to each other in the horizontal direction other than the vertical direction. Even in that case, when the lower rail constituent member 14 moves, the runner or the shielding member fixing member can be prevented from falling by supporting the runner or the shielding member fixing member from below.

  In the above example, the rail is composed of the upper rail constituent member 12 that defines the upper portion of the rail space and the lower rail constituent member 14 that defines the lower portion of the rail space. For example, the rail may be composed of a first rail constituent member that defines a front portion of the rail space and a second rail constituent member that defines a rear portion of the rail space. In addition, it is also possible to configure a first rail constituent member and a second rail constituent member that share and define an arbitrary portion of the other rail space. In any case, the first rail component member and the second rail component member are separated so that an open space in which the shielding material support member can be attached and detached can be formed. As long as one of the first rail constituent member and the second rail constituent member or both of them are movable.

  In the above example, the upper rail constituent member 12 and the lower rail constituent member 14 are automatically combined to form the rail space by being close to each other as much as possible, but the rail space is configured more reliably. Therefore, it is also possible to separately provide an engaging means for engaging the upper rail constituent member 12 and the lower rail constituent member 14 in a state where they are as close as possible and a releasing means for releasing the engaging means. It is.
