  However, in the vertical blind of Patent Document 1, the rear end runner can be moved. However, even if all the slats as the shielding material are folded into the proximal end side or the distal end side, the shielding material is set as the blind. There is no change in occupying a part of the window which is an opening, and there is a problem that a shielding material is applied to a part of the window.

  On the other hand, in order to prevent the shielding material from covering the opening when the shielding material is folded, it can be considered that the width of the blind is made larger than the width of the opening in which the blind is set. However, in this case, there is a problem that when all the shielding material is pulled out, useless shielding material that does not shield the opening is generated. There is also a problem that it is difficult to accurately determine how much the width of the blind is increased so that the shielding material does not cover the opening when the shielding material is folded.

  The present invention has been made in view of such a problem, and when the shielding material is folded, the shielding material is not applied to the opening in which the vertical blind is set, and the width dimension of the vertical blind is calculated. It is an object of the present invention to provide a vertical blind that can be easily performed.

In order to achieve the above-described object, according to the first aspect of the present invention, a shielding material is suspended and supported from each of a plurality of carriers movable in the head rail, and the leading carrier is moved to move the leading carrier. In the vertical blind that pulls the shielding material by pulling the sequentially connected carrier with the top carrier, or pushes the carrier sequentially connected to the top carrier with the top carrier and folds the shielding material,
Within the head rail, a stopper is provided that restricts movement of the rearmost carrier in the direction of the other end of the head carrier in a direction equal to or more than a predetermined amount among the carriers sequentially connected to the front carrier,
When the leading carrier is moved and the shielding material is pulled out completely, the rearmost carrier located on one end of the head rail moves toward the other end of the head rail until it is regulated by the stopper, and the head A space without a shielding material is formed below the rail one end side, and when the shielding material is folded, all carriers including the leading carrier are positioned on the head rail one end side with respect to the stopper .

  According to a second aspect of the present invention, in the first aspect, the portion occupied by the shielding material when the leading carrier is moved and the shielding material is completely pulled out, and the shielding material is completely moved by moving the leading carrier. A portion occupied by the shielding material when folded is not overlapped in the width direction.

According to a third aspect of the present invention, the length in the width direction of the space without the shielding material formed under one end of the head rail according to the first or second aspect shields the opening in which the vertical blind is set. It is characterized by being substantially equal to the folding allowance when the shielding material necessary for the folding is folded .

According to the first aspect of the present invention, when the leading carrier is moved and the shielding material is completely pulled out, a space without the shielding material is formed below the one end portion of the head rail. An opening that is shielded by the shielding material when pulled out and a space in which the shielding material is folded can be provided separately. Therefore, when the shielding material is folded, the shielding material can be prevented from covering the opening, and the opening can be sufficiently opened.

When the shielding material is completely pulled out, the shielding material can exclusively shield the opening, so that it is possible to suppress generation of a useless shielding material that does not shield the opening.
In addition, by providing a stopper that restricts the movement of the rearmost carrier by a predetermined amount or more, even if the rearmost carrier is pulled strongly by another carrier, the rearmost carrier can be stopped at a predetermined position and shielded. The opening can be reliably shielded by the material.

  According to the invention described in claim 2, when the leading carrier is moved and the shielding material is completely pulled out, the portion occupied by the shielding material and when the leading carrier is moved and the shielding material is completely folded are shielded. By preventing the portion occupied by the material from overlapping in the width direction, it is possible to prevent the shielding material from covering the opening at all when the shielding material is folded.

According to the third aspect of the present invention, the length in the width direction of the space without the shielding material formed below the one end portion of the head rail is the shielding material necessary for shielding the opening in which the vertical blind is set. Since it is substantially equal to the folding allowance when the is folded, the length of the head rail in the width direction can be easily calculated .

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

(First embodiment)
FIG. 1 is a front view showing a vertical blind according to the first embodiment of the present invention.
In the figure, the vertical blind is set in an opening 30 such as a window, and has a head rail 10 fixed to a window frame, a wall surface or the like by a bracket. A plurality of carriers 12 are arranged in the head rail 10 so as to be slidable in the longitudinal direction, and a louver 14 is suspended and supported on each carrier 12 via a hook 13 (see FIGS. 4 to 6). ing.

  Among the plurality of carriers 12, the carrier on the first end portion 10a side of the head rail 10 is a leading carrier (master carrier) 12A, and an operation code 16 is connected to the leading carrier 12A.

  One end of the operation cord 16 is connected to the leading carrier 12A and is turned back at the first end portion 10a toward the first end portion 10a of the head rail 10, and then the inside of the head rail 10 is moved to the head rail 10. All the carriers 12 are inserted toward the second end portion 10b of the head rail 10, and after being led out from the second end portion 10b of the head rail 10, the carrier 12 other than the leading carrier 12A is inserted by folding back. The other end is connected to the top carrier 12A and is endless. The portion of the operation cord 16 that is led out from the second end portion 10 b of the head rail 10 and folded back constitutes the first operation portion 20. The folded portion of the first operation unit 20 passes through the weight 21.

  Each carrier 12 is connected by a spacer link 15 (see FIGS. 4 to 6) with the leading carrier 12A as the leading and a predetermined interval determined by the adjacent carrier 12 and the spacer link 15 as a maximum interval.

  All the carriers 12 are fitted with tilt rods 24 (see FIGS. 4 to 6) extending in the longitudinal direction in the head rail 10. The tilt rod 24 is rotatably supported in the head rail 10 and is connected to the operation rod 28 (second operation portion) via a gear such as a bevel gear at the second end portion 10 b of the head rail 10. ing.

  Each carrier 12 is provided with a rotation transmission mechanism that meshes with the tilt rod 24. The rotation transmission mechanism transmits the rotation of the tilt rod 24 to the hook 13 of the carrier 12. When the operation rod 28 is operated and rotated, the rotation is transmitted to the tilt rod 24, whereby the hook 13 of each carrier 12 is rotated via the rotation transmission mechanism of the carrier 12 and the louver 14 is rotated. Can be done.

  The length of the head rail 10 in the width direction, that is, the width dimension is set to be longer than the width dimension of the opening 30 in which the vertical blind is set. That is, the head rail 10 has an extension portion 10c that is longer than the conventional head rail, and the second end portion 10b of the head rail 10 is an end portion of the extension portion 10c.

  Among the plurality of carriers 12, the carrier on the second end 10b side of the head rail 10 is the rearmost carrier 12B, and the rearmost carrier 12B is different from the rearmost carrier of the conventional vertical blind, It can be separated from the second end 10b. As shown in FIG. 6B, only the rearmost carrier 12B has protrusions 12a on both sides thereof.

  A first stopper 10d capable of contacting the leading carrier 12A is provided near the first end 10a of the head rail 10, and a second stopper capable of contacting the rearmost carrier 12B is disposed near the second end 10b. 10e is provided, and a third stopper 10f is provided in the vicinity of the boundary between the extended portion 10c and the non-extended portion of the head rail 10, and the third stopper 10f interferes with the protruding portion 12a of the rearmost carrier 12B. It is possible.

  In the vertical blind configured as described above, the opening 30 can be shielded or opened by operating the first operation unit 20 and moving the leading carrier 12A, as in the conventional vertical blind. it can.

  Specifically, when the leading carrier 12A is moved toward the first end portion 10a and the remaining carriers 12 are sequentially pulled by the leading carrier 12A, the louver 14 is pulled out.

  The leading carrier 12A can be moved until it comes into contact with the first stopper 10d. At this time, the rearmost carrier 12B interferes with the third stopper 10f, and the third stopper 10f causes the rearmost carrier 12B to move further toward the non-extension portion than near the boundary between the extension portion 10c and the non-extension portion of the head rail 10. In the state where the rearmost carrier 12B is located near the boundary between the extension portion 10c and the non-extension portion of the head rail 10 and thus the louver 14 is completely pulled out, FIG. As shown, almost all of the louvers 14 are in positions where they overlap with the openings 30, and a space without the louvers 14 is formed below the second end 10 b side of the head rail 10. When the operation rod 28 is operated to rotate the louver 14, the opening 30 can be completely shielded as shown in FIG. Even if the rearmost carrier 12B is vigorously pulled by the other carrier 12 by the third stopper 10f, the rearmost carrier 12B can be stopped near the boundary between the extended portion 10c and the non-extended portion. 30 can be reliably shielded.

  On the contrary, when the leading carrier 12A is moved toward the second end portion 10b and the remaining carriers 12 are sequentially pushed out by the leading carrier 12A, the louver 14 is folded. The first carrier 12A can be moved until the rearmost carrier 12B comes into contact with the second stopper 10e. At this time, the carrier 12 other than the rearmost carrier 12B and the leading carrier 12A are not provided with the protruding portion 12a, and therefore can pass without interfering with the third stopper 10f. Thus, in a state where the louvers 14 are completely folded, as shown in FIG. 3, all the louvers 14 are located in the extension portions 10 c and are not overlapped with the openings 30. Therefore, the louver 14 can be prevented from covering the opening 30, and the opening 30 can be completely opened.

  In this way, when the louver 14 is completely pulled out, the portion occupied by the louver 14 and the portion occupied by the louver when the louver 14 is completely folded are not overlapped in the width direction. It is possible to prevent the louver 14 from covering the opening 30 when it is fully folded. However, some overlap in the width direction can be set within an allowable range.

  The number of louvers 14 that are suspended and supported by the carrier 12 and the carrier 12 is a number that can completely cover the opening 30 in a state where the louver 14 is completely pulled out. Therefore, if the length of the extension portion 10c is equal to or longer than the folding allowance when the number of louvers 14 are folded, the louver 14 does not cover the opening 30 when the louvers 14 are folded. Can be.

  That is, the length of the extension portion 10c, that is, the length in the width direction of the space without the louver 14 below the second end portion 10b of the head rail 10 formed in FIG. The required amount of folding of the required number of louvers 14 (in other words, the total length when the carriers 12 of the number of louvers 14 necessary to completely cover the opening 30 are arranged in the width direction) is + α (the margin). It can be easily obtained from the folding cost. By appropriately reducing α and making the length of the extension portion 10c substantially the same as the folding allowance, the louver 14 can be prevented from covering the opening 30 when the louver 14 is folded, and the head The length of the rail 10 can be made into a length that is not wasted, and the moving distance of the louver 14 can be made to be not wasted.

  On the other hand, as shown in FIG. 7, in order to prevent the louver from being covered with the opening 30 when the louver is folded, the width dimension of the head rail 10 is simply made longer than the opening, If fixed, the length of the extension must be determined after taking into account the number of louvers suspended from the extension. However, since the number of louvers suspended from the extension part itself depends on the length of the extension part, the length of the extension part cannot be easily determined. Further, the length of the obtained extension portion should be longer by the amount of the louver hung from the extension portion, and the louver hung from the extension portion does not contribute to shielding the opening. Although it becomes an unnecessary louver, if it is the head rail 10 of this invention, generation | occurrence | production of such an unnecessary louver can be suppressed.

(Second Embodiment)
FIG. 8 is a front view showing a vertical blind according to the second embodiment of the present invention.
In this embodiment, the head rail 10 has extension portions 10c that are longer than the conventional head rail at both ends thereof. Of the plurality of carriers 12, the two carriers at the center are the master carriers 12A and 12A that are the leading carriers.

  One end of the operation cord 16 is connected to one leading carrier 12A on the second end portion 10b side, and the inside of the head rail 10 is directed to the first end portion 10a toward the first end portion 10a of the head rail 10. After inserting the other leading carrier 12A on the part 10a side and the other carrier 12 on the first end part 10a side, turning back the first end part 10a of the head rail 10, and then inserting the carrier 12 again, Connected to the other top carrier 12A, toward the second end 10b of the head rail 10, the inside of the head rail 10 and the other carrier 12 on the one top carrier 12A and the second end 10b side After being inserted and led out from the second end portion 10b of the head rail 10, it is folded back, inserted through the carrier 12 again, toward the one leading carrier 12A, and the other end is one It is connected to the head carrier 12A, the endless. The portion of the operation cord 16 that is led out from the second end portion 10 b of the head rail 10 and folded back constitutes the first operation portion 20. The folded portion of the first operation unit 20 passes through the weight 21.

  Each carrier 12 closer to the second end 10b than the first carrier 12A on the second end 10b side is separated from the adjacent carrier 12 by a spacer link 15 with the first carrier 12A at the head. Each carrier 12 that is connected to the first end 10a side with respect to the other first carrier 10A on the first end 10a side is connected to the other first carrier 12A by the spacer link 15. And a predetermined interval determined by the adjacent carrier 12 and the spacer link 15 as a maximum interval.

  Among the plurality of carriers 12, the carriers on the first end 10a side and the second end 10b side of the head rail 10 are the rearmost carriers 12B and 12B, respectively, and the rearmost carriers 12B and 12B are the conventional vertical carriers. Unlike the last carrier of the mold blind, the head rail 10 can be separated from the first end 10a and the second end 10b.

  Near the center of the head rail 10, there is provided a first stopper 10d that can contact the leading carriers 12A, 12A. Near the first end 10a and the second end 10b, the last carriers 12B, 12B A second stopper (not shown) capable of contacting is provided, and third stoppers 10f and 10f are provided in the vicinity of the boundary between the extension portion 10c and the non-extension portion of the head rail 10, and the third stopper 10f, 10f can only interfere with the rearmost carrier 12B.

  In the vertical blind configured as described above, the opening 30 can be shielded or opened by operating the first operating unit 20 and moving the leading carrier 12A.

  Specifically, when the two leading carriers 12A are moved toward the center and the remaining carriers 12 are sequentially pulled by the leading carrier 12A, the louver 14 is pulled out.

  Each leading carrier 12A can be moved until it comes into contact with the first stopper 10d. At this time, each rear end carrier 12B interferes with the third stopper 10f, and the third end stopper 10f causes the rear end carrier 12B to be further in the non-extension portion than near the boundary between the extension portion 10c and the non-extension portion of the head rail 10. Therefore, the rearmost carrier 12B is located near the boundary between the extension portion 10c and the non-extension portion of the head rail 10, and thus the louver 14 is completely pulled out in the state shown in FIG. As shown in FIG. 8, almost all the louvers 14 are in positions where they overlap the opening 30. Therefore, when the operation rod 28 is operated to rotate the louver 14, the opening 30 can be completely shielded as shown in FIG.

  On the contrary, when the leading carriers 12A and 12A are moved toward the first end 10a and the second end 10b, respectively, and the remaining carriers 12 are sequentially pushed out by the leading carriers 12A and 12A, the louver 14 is folded. It will be rare. Each leading carrier 12A can be moved until each trailing end carrier 12B comes into contact with each second stopper 10e. At this time, the carrier 12 and the leading carrier 12A other than the rearmost carrier 12B can pass without interfering with the third stopper 10f. Thus, in a state where the louvers 14 are completely folded, as shown in FIG. 10, all the louvers 14 are located in the respective extension portions 10 c and are not overlapped with the openings 30. Therefore, the louver 14 can be prevented from covering the opening 30, and the opening 30 can be completely opened.

  As described above, even when the extended portions 10c and 10c are located at both ends of the head rail 10, the same action as in the first embodiment can be performed. The length of each extension 10c is about 1/2 + α (the margin) of the number of louvers 14 required to completely cover the openings 30, and can be easily obtained from the amount of folds.
