Here, the guide rail of the present invention can be used for various types of shielding devices such as horizontal blinds, vertical blinds, roll screens, pleated screens, and curtains. However, below, the case where the guide rail of this invention is used for a horizontal blind is demonstrated.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The directions of “front”, “rear”, “left”, “right”, “upper”, and “lower” noted in the drawings are “front”, “rear”, “left”, “right”, “ Each corresponds to the direction described as “up” or “down”. However, the positional relationship of each configuration of the horizontal blind and the guide rail according to the present embodiment is not limited to the concept of “front”, “rear”, “left”, “right”, “upper”, and “lower”.

First, an outline of the configuration of the horizontal blind and guide rail according to the present embodiment will be described with reference to FIG.

As shown in FIGS. 1A and 1B, a horizontal frame 1 and a guide are provided on a frame 11 having a square frame provided on the indoor side of a sash (not shown) provided with a window glass 10. A rail 20 is installed. In addition, you may install a horizontal blind and a guide rail with respect to frame of shapes (for example, round frame shape) other than square frame shape.

<Configuration of horizontal blind>
The horizontal blind 1 has a head box 2 attached to the inner surface of an upper edge portion 11a (upper frame portion) constituting the upper side of the frame 11 via a bracket (not shown).

The ladder cord 3 is suspended from a plurality of locations in the length direction of the head box 2 (two locations in the illustrated example). Each ladder cord 3 supports a plurality of slats 4 (shielding members) that can be suspended from the lower side of the head box 2 and that can rotate about a horizontal direction (horizontal direction) as a rotation axis. Each slat 4 is made of a light shielding material having a light shielding property (for example, a metal such as aluminum). Each slat 4 may be made of a material having a low light shielding property (for example, a resin such as plastic). A bottom rail 5 is connected to the lower end of each ladder cord 3, and an upper end portion of each ladder cord 3 is connected to a drive shaft (not shown) that is rotatably supported in the head box 2. Yes.

Further, an operation pole 6 that is connected to the drive shaft and can be rotated by an operator is suspended from one end (left end in the illustrated example) of the head box 2. The operation pole 6 is a pole for adjusting (opening / closing) the angle of the slat 4.

When the operator rotates the operation pole 6 to rotate the drive shaft, each slat 4 rotates about the horizontal axis as the rotation axis through the ladder cord 3 by the rotation of the drive shaft, and the angle of the slat 4 varies. .

In addition, lifting cords (not shown) are respectively suspended from the vicinity of the suspended position of the plurality of ladder cords 3 in the head box 2. Each lifting / lowering cord is inserted through an insertion hole (not shown) formed in the vicinity of a position where the ladder cord 3 of each slat 4 is supported, and the lower end is connected to the bottom rail 5. Further, the upper end of each lifting / lowering cord is guided to one end of the head box 2 and is suspended from the head box 2 via a stopper device 9 provided at one end of the head box 2. An operation cord 7 that can be operated by an operator is connected to each lifting cord suspended from the head box 2 via a cord equalizer 8. The operation code 7 is a code for raising (raising) and lowering the slat 4.

When the operator operates the operation cord 7 and pulls the lifting / lowering cord from the head box 2, the bottom rail 5 is pulled up and is sequentially pulled up from the lower slat 4. Further, when the operator operates the operation cord 7 to draw the lifting / lowering cord into the head box 2 based on the weight of the bottom rail 5 and the slat 4, the bottom rail 5 is lowered and the ladder cord 3 sequentially from the upper slat 4. It returns to the state supported by. When the operator releases the operation cord 7, the stopper device 9 is actuated to prevent the bottom rail 5 from falling by its own weight, and the slat 4 is suspended and supported at a desired height.

In addition, the structure of the horizontal blind 1 demonstrated above is an example to the last, and a structure other than the above may be sufficient. For example, in the above description, the operation method of the horizontal blind 1 is a so-called “pole type” in which the angle adjustment of the slat 4 is performed by the operation pole 6 and the slat 4 is moved up and down by the operation cord 7. The method is not limited to the pole type, and may be another method.

<Configuration of guide rail>
The guide rail 20 is a rail that can guide the end portion of the slat 4 of the horizontal blind 1. In the present embodiment, the guide rail 20 is configured by two vertical guide portions 21 and 21 that can guide the left and right end portions of the slat 4. One vertical guide portion 21 is installed on the left edge portion 11 b constituting the left side of the frame 11 and can guide the left end portion of the slat 4, and the other vertical guide portion 21 constitutes the right side of the frame 11. The right edge portion 11c of the slat 4 can be guided.

In addition, you may install the vertical guide part 21 with respect to any one of the left edge part 11b and the right edge part 11c (In this case, the vertical guide installed in either one of the left edge part 11b or the right edge part 11c) Part 21 constitutes a guide rail). Alternatively, instead of installing the vertical guide portion 21, a horizontal guide portion may be installed on the lower edge portion 11d constituting the lower side of the frame 11 (in this case, a guide rail is constituted by the horizontal guide portion). Alternatively, in addition to installing the vertical guide portion 21, a horizontal guide portion may be installed with respect to the lower edge portion 11d (in this case, the guide rail is configured by the vertical guide portion 21 and the horizontal guide portion). .

Each vertical guide portion 21 includes a non-moving portion 22 and a moving portion 23 (first moving portion, second moving portion), and a predetermined length from the upper end (one end) is configured by the non-moving portion 22. Below the moving unit 22 (a portion other than the non-moving unit) is configured by the moving unit 23. In other words, the non-moving part 22 has a corresponding edge (the left edge part 11b in the vertical guide part 21 installed on the left edge part 11b. The right edge part 11c in the vertical guide part 21 installed on the right edge part 11c). Of these, the moving part 23 is arranged below the non-moving part 22 among the corresponding edge parts.

In the present embodiment, the predetermined length, that is, the length of the non-moving part 22 is pulled up to the upper limit position as shown in FIG. 1B and folded (hereinafter referred to as “folded state” as appropriate). The height direction dimensions of the multi-stage slats 4 (specifically, the height direction dimensions of the multi-stage slats 4 in the folded state and the height direction of the head box 2 and the bottom rail 5 at the upper and lower ends thereof) In other words, it is substantially equal to the length of the folding allowance of the multi-stage slats 4. Hereinafter, the slat 4, the head box 2, and the bottom rail 5 will be collectively referred to as “slat 4 etc.” as appropriate. That is, the non-moving part 22 is arranged in the corresponding edge from the upper end by the length of the above folding allowance (the part where the slats 4 and the like are present even when the slats 4 are in the folded state). Is arranged below the non-moving part 22 in the corresponding edge part (the part without the slats 4 or the like in a situation where the slats 4 of the plurality of stages are in the folded state). The predetermined length (the length of the non-moving part 22) may be shorter or longer than the length of the folding space.

Each non-moving part 22 has an attaching part 24 (first attaching part) and one shielding part 25 (first shielding part) connected to the attaching part 24 so as not to move.

The attachment part 24 is attached to the length of the tatami mat from the upper end of the inner surface of the corresponding edge. The shielding portion 25 includes a gap S1 between the left and right end portions of the slats 4 arranged to face the attachment portion 24 among the plurality of slats 4 and a portion to which the attachment portion 24 is attached on the inner surface of the corresponding edge portion. It can be shielded. In this embodiment, the attachment part 24 is attached so that the shielding part 25 can shield the gap S1 between the slat 4 and the window glass 10 (outside of the slat 4). The attachment portion 24 may be attached so that the shielding portion 25 can shield the gap S1 on the side opposite to the window glass 10 of the slat 4 (inner side of the slat 4).

Each moving portion 23 includes an attachment portion 26 (second attachment portion, third attachment portion), and one shielding portion 27 (second shielding portion, third shielding portion) movably connected to the attachment portion 26. Have

The attachment portion 26 is attached below the attachment portion 24 of the non-moving portion 22 in the inner surface of the corresponding edge portion. The shielding portion 27 includes a gap S2 between the left and right end portions of the slats 4 arranged to face the attachment portion 26 in the plurality of slats 4 and a portion to which the attachment portion 26 is attached among the inner surfaces of the corresponding edge portions. It can be shielded. That is, the shielding portion 27 is in a later-described shielding state (the state of FIG. 1A) when shielding the gap S2, and when not shielding, the shielding portion 27 is in a later-described non-shielding state (FIG. 1 ( It is connected to the mounting portion 26 so as to be in the state b). In this embodiment, the attachment part 26 is attached so that the shielding part 27 in the shielding state can shield the gap S2 between the slat 4 and the window glass 10 (outside of the slat 4). The attachment portion 26 may be attached so that the shielding portion 27 in the shielding state can shield the gap S2 on the side opposite to the window glass 10 of the slat 4 (inner side of the slat 4).

Next, the configuration of the non-moving part 22 and the moving part 23 of the vertical guide part 21 will be described in detail with reference to FIGS. 2 and 3, in order to make the structure easy to see, the length of the moving portion 23 of the vertical guide portion 21 is shortened in the vertical direction (the lower side of the moving portion 23 is omitted). Yes.

Here, in the present embodiment, the vertical guide portion 21 installed on the left edge portion 11b and the vertical guide portion 21 installed on the right edge portion 11c have a bilaterally symmetric structure. Below, the structure of the non-moving part 22 and the moving part 23 of the vertical guide part 21 installed in the right edge part 11c is demonstrated as a representative. In the following description, when the non-moving part 22 or the moving part 23 is simply referred to, the non-moving part 22 or the moving part 23 or the like of the vertical guide part 21 installed on the right edge part 11c is assumed. . The structure of the non-moving part 22 and the moving part 23 of the vertical guide part 21 installed in the left edge part 11b is the non-moving part 22 and the moving part 23 of the vertical guide part 21 installed in the right edge part 11c described below. Since the configuration is symmetrical, the description is omitted.

In addition, the vertical guide part installed in the left edge part 11b and the vertical guide part installed in the right edge part 11c are made into the same structure (common product), and these two vertical guide parts are left-right symmetrically. You may arrange | position to the edge part 11b and the right edge part 11c, respectively.

<Configuration of non-moving part>
As shown in FIGS. 2 and 3, the non-moving portion 22 includes the rectangular thin plate-shaped attachment portion 24 and the rectangular thin plate-shaped shielding portion 25.

The mounting portion 24 and the shielding portion 25 are integrally formed (one member) with a light shielding material (for example, a metal such as aluminum) having a light shielding property. In addition, you may comprise the attachment part 24 and the shielding part 25 integrally by the material (for example, resin, such as a plastics) with low light-shielding property. In this case, it is preferable to improve the light shielding property of the shielding part 25 by attaching a light shielding member (such as a light shielding plate) to the surface or inside of the shielding part 25. Or you may comprise the attaching part 24 and the shielding part 25 as a different body (separate member). In this case, the shielding part 25 is made of a light shielding material to ensure the light shielding property in the shielding part 25, or a member (shielding plate or the like) having a light shielding property is attached to the surface or inside of the shielding part 25, It is preferable to improve the light shielding property at 25.

The left surface of the mounting portion 24 (the surface facing the right end of the slat 4) is provided with a groove portion 241 that is recessed in the thickness direction of the mounting portion 24 and has a predetermined width along the vertical direction. A through hole (not shown) through which a mounting screw (not shown) passes is provided on the bottom surface of the groove 241. At this time, the groove portion 241 may be configured so that the head portion of the mounting screw screwed into the right edge portion 11c as described later can be accommodated inside so as not to protrude from the left surface of the mounting portion 24. . Further, the groove portion 241 may not be provided on the left surface of the attachment portion 24, and a through hole may be provided on the left surface. And the attachment part 24 is attached to the length of the said folding | fitting allowance from the upper end among the inner surfaces of the right edge part 11c because the screw for attachment penetrates the through-hole, and is screwed to the right edge part 11c. In addition, you may attach the attaching part 24 using fixing members (for example, adhesives etc.) other than a screw (In this case, the said through-hole may be abbreviate | omitted).

The shielding portion 25 is connected to the mounting portion 24 so as to be immovable on the rear end portion (width direction end portion) side of the mounting portion 24 so that the width direction thereof is substantially perpendicular to the width direction of the mounting portion 24. ing. Therefore, the non-moving part 22 has a substantially L shape in plan view as a whole.

Further, the shielding part 25 includes a connecting part 28 between the shielding part 25 and a shielding part 27 that is in a shielding state described later (the state shown in FIG. 2) in the moving part 23 disposed below the non-moving part 22. A lid portion 251 is provided for covering. The lid portion 251 is formed as a flange portion projecting downward from the rear side of the lower end portion of the shielding portion 25. And the cover part 251 can cover the connection part 28, and can perform the shielding in the said connection part 28 because the upper end part of the shielding part 27 contacts or adjoins to the front side. The lid portion 251 is not limited to the flange portion protruding downward from the rear side of the lower end portion of the shielding portion 25 as described above, and may be any one that can cover the connection portion 28. Anything is acceptable. In addition, a lid for covering the connecting portion 28 may be provided in the shielding portion 27 of the moving portion 23 instead of or in addition to the shielding portion 25.

The configuration of the non-moving unit 22 described above is merely an example, and a configuration other than the above may be used.

<Configuration of moving unit>
As shown in FIGS. 2 to 9, the moving unit 23 includes the rectangular thin plate-like attachment portion 26 and the rectangular thin plate-like shielding portion 27.

The mounting portion 26 and the shielding portion 27 are configured as separate bodies. The shielding part 27 is made of a light shielding material having a light shielding property (for example, a metal such as aluminum). In addition, you may comprise the shielding part 27 with materials (for example, resin, such as a plastics) with low light-shielding property. In this case, it is preferable to improve the light shielding property of the shielding part 27 by attaching a light shielding member (such as a light shielding plate) to the surface or inside of the shielding part 27.

A groove portion 261 configured in the same manner as the groove portion 241 is provided on the left surface of the attachment portion 26 (the surface on the side facing the right end portion of the slat 4). In addition, the groove part 261 may not be provided in the left surface of the attachment part 26, but a through hole may be provided in the left surface. Then, the mounting screw 29 passes through a through hole (not shown) on the bottom surface of the groove portion 261 and is screwed into the right edge portion 11c, so that the mounting portion 26 is not moved among the inner surfaces of the right edge portion 11c. It is attached below the attachment part 24 of the part 22. At this time, the head of the screw 29 screwed to the right edge portion 11c is not projected from the left surface of the attachment portion 26 and is housed in the groove portion 261 (see FIGS. 4 and 5). In addition, you may attach the attaching part 26 using fixing members (for example, adhesives etc.) other than the screw 29 (In this case, the said through-hole may be abbreviate | omitted).

When the shielding portion 27 shields the gap S2, the width direction of the shielding portion 27 is substantially perpendicular to the width direction of the mounting portion 26 (the states shown in FIGS. 1A, 2 and 4). When not, the rear end of the mounting portion 26 is set so that its width direction is in a non-shielding state (the state shown in FIGS. 1B, 3 and 5) substantially parallel to the width direction of the mounting portion 26. On the side of the portion (width direction end portion), the attachment portion 26 is movably connected. Therefore, when the shielding part 27 is in the shielding state, the moving part 23 is generally L-shaped in plan view.

In the present embodiment, the shielding portion 27 is rotatably connected to the mounting portion 26 on the rear end side of the mounting portion 26. Specifically, the shielding part 27 becomes a non-shielding state by rotating to the front side (attachment part 26 side) so as to be close to the attachment part 26 in the shielding state, and the attachment part 26 in the non-shielding state. By rotating to the left so as to be separated from each other, it is connected to the mounting portion 26 so as to be in a shielding state. For this reason, the shielding state in the shielding part 27 can be said to be the state in which the shielding part 27 is opened (the unfolded state), and the non-shielding state in the shielding part 27 is the state in which the shielding part 27 is closed (the folded state). I can say that. In this example, when the shielding portion 27 is rotated to the left with respect to the attachment portion 26, the width direction base end portion (the end portion on the side where a hinge piece portion 231 described later) is provided is the right edge portion. By making contact with the inner surface of 11 c and making it impossible to rotate to the rear side, the width direction of the mounting portion 26 is in a shielding state substantially perpendicular to the width direction. In addition, when the shielding part 27 is rotated to the left side so as to be separated from the attachment part 26 in the shielding state, the shielding part 27 becomes a non-shielding state. You may connect with the attaching part 26 so that it may be in a shielding state by moving.

<Details of connection mode between shielding portion and attachment portion in moving portion>

The plurality of hinge piece portions 231 are provided along the vertical direction with respect to the width direction base end portion of the shielding portion 27, and a long portion having a long hole along the vertical direction is arranged in the length direction, that is, the vertical direction. It is formed by cutting into a comb tooth shape at a predetermined pitch along the direction. In addition, the said elongate part of the shielding part 27 may be comprised integrally with the said shielding part 27, and may be comprised as a different body. That is, the long part of the shielding part 27 is notched and cut out at a predetermined pitch along the vertical direction using an appropriate jig, so that the long part remains at the predetermined pitch along the vertical direction. The plurality of portions are hinge piece portions 231 respectively. In addition, you may arrange | position by attaching the several hinge piece part 231 which is a completed product instead of arrange | positioning the several hinge piece part 231 by performing the above notch processes.

The plurality of hinge pieces 232 are provided at a predetermined pitch along the length direction, that is, the vertical direction with respect to the rear end portion of the attachment portion 26, and each hinge piece 232 has a through-hole along the vertical direction. 235 is provided. The plurality of hinge pieces 232 are provided along the vertical direction with respect to the rear end of the attachment portion 26, and a long portion having a long hole along the vertical direction is cut in the same manner as the hinge piece 231. It is formed by chipping. In addition, the said elongate part of the attaching part 26 may be comprised integrally with the said attaching part 26, and may be comprised as a different body. Moreover, you may arrange | position by attaching the several hinge piece part 232 which is a completed product instead of arrange | positioning the several hinge piece part 232 by notching.

And in the state which the shielding part 27 and the attachment part 26 were connected so that the hinge piece parts 231 and 232 may be arrange | positioned alternately and the through-hole 234 and the through-hole 235 may be connected, those one end sides (for example, The plurality of hinge pieces 231 can be rotated with respect to the plurality of hinge pieces 232 about the pin 233 as a rotation fulcrum by inserting the pins 233 into the through holes 234 and 235 respectively from the lower end side). The hinge piece 231 and the plurality of hinge pieces 232 are connected (see FIGS. 6A and 6B).

As described above, the plurality of hinge pieces 231 and the plurality of hinge pieces 232 are connected by the pins 233, and the plurality of hinge pieces 231 can be rotated with respect to the plurality of hinge pieces 232 using the pins 233 as rotation fulcrums. Thus, the shielding part 27 is rotatable with respect to the attachment part 26 on the rear end side of the attachment part 26.

That is, when the shielding part 27 is in the shielding state, the plurality of hinge pieces 231 rotate in conjunction with the front side with respect to the plurality of hinge pieces 232 with the pin 233 serving as a rotation fulcrum. On the rear end side of the attachment portion 26, the attachment portion 26 can be turned to the front side to be in an unshielded state. In addition, when the shielding part 27 is in a non-shielding state, the plurality of hinge pieces 231 are rotated in conjunction with the left and right with respect to the plurality of hinge pieces 232 with the pin 233 serving as a rotation fulcrum. In the rear end portion side of the attachment portion 26, it is possible to turn to the left side with respect to the attachment portion 26 and enter a shielding state.

It should be noted that the configuration and operation of the hinge mechanism 230 described above are merely examples, and configurations and operations other than those described above may be used.

Further, the shielding part 27 is provided with a locking part 271 for locking the shielding part 27 in a non-shielding state. The locking portion 271 is formed as a ridge protruding from the outer peripheral surface of the hinge piece 231 along the vertical direction. Then, the locking portion 271 is locked on the right side of the rear end portion of the mounting portion 26 when the shielding portion 27 rotates to the front side with respect to the mounting portion 26 and enters a non-shielding state. The shielding part 27 can be locked in a non-shielding state by suppressing the leftward rotation of the shielding part 27. In addition, the latching | locking part 271 is not limited to the protrusion part protruded along the up-down direction from the outer peripheral surface of the above hinge piece parts 231, but can lock the shielding part 27 in a non-shielding state. Any thing can be used. Further, a locking portion for locking the shielding portion 27 in a non-shielding state may be provided in the attachment portion 26 instead of or in addition to the shielding portion 27. However, at least one of the shielding part 27 and the attachment part 26 is not necessarily provided with a locking part for locking the shielding part 27 in a non-shielding state.

Note that the configuration and operation of the moving unit 23 described above are merely examples, and configurations and operations other than those described above may be used.

<Effects of this embodiment>
As described above, in the present embodiment, the predetermined length from the upper end of the vertical guide portion 21 is constituted by the non-moving portion 22, and the lower portion of the non-moving portion 22 is constituted by the moving portion 23. When the slats 4 shield the solar radiation, the line of sight, etc., the shielding part 27 of the moving part 23 is kept in a shielding state, so that the gaps S1 and S2 described above are separated from the shielding part 25 of the non-moving part 22 and the moving part. It is possible to shield by 23 shielding portions 27. As a result, it is possible to shield solar radiation, line of sight, etc. from the gaps S1, S2. On the other hand, when the slat 4 is not shielded, that is, when the slat 4 is lifted and the inside of the frame 11 is opened, the moving part 23 in the shielded state is moved with respect to the non-movable part 22 to be in a non-shielded state. Since the open space inside the frame 11 can be made larger, solar radiation can be taken in efficiently.

Here, a structure is also considered in which the moving portion is also a predetermined length from the upper end of the vertical guide portion, that is, the moving portion is configured from the upper end to the lower end of the vertical guide portion. However, a predetermined length from the upper end of the vertical guide portion is a portion where the slats 4 and the like exist even when the slats 4 of a plurality of stages are folded. Therefore, if this part is a moving part, when the inner side of the frame 11 is opened by folding the slats 4 in a plurality of stages, the shielding part of the moving part interferes with the slats 4 etc. in the folded state. In some cases, the non-shielding state cannot be achieved.

On the other hand, in the present embodiment, as described above, the non-moving portion 22 removes a portion having a slat 4 or the like by a predetermined length from the upper end of the vertical guide portion 21, that is, even when a plurality of slats 4 are folded. The moving portion 23 is configured below the non-moving portion 22. As a result, when the slats 4 of a plurality of stages are folded and the inside of the frame 11 is opened, the shielding part 27 of the moving part 23 is brought into a non-shielding state without interfering with the slats 4 and the like in the folded state. can do.

In the present embodiment, in particular, when the shielding portion 25 is connected to the attachment portion 24 so that the width direction thereof is substantially perpendicular to the width direction of the attachment portion 24, and the shielding portion 27 shields the gap S2. The width direction of the mounting portion 26 is in a shielding state substantially perpendicular to the width direction of the mounting portion 26, and when the shielding is not performed, the width direction is in a non-shielding state substantially parallel to the width direction of the mounting portion 26. , Connected to the mounting portion 26. Accordingly, the gaps S1 and S2 can be shielded by the shielding part 25 and the shielding part 27 in the shielding state. Moreover, since the finding dimension of the vertical guide part 21 can be made small by making the shielding part 27 into a non-shielding state, the open space inside the frame 11 can be made larger.

In the present embodiment, in particular, the length of the non-moving part 22 is substantially equal to the length of the folding allowance of the multi-stage slats 4. As a result, when the inner side of the frame 11 is opened with the slats 4 in a plurality of stages in a folded state, the shielding part 27 of the moving unit 23 is brought into a non-shielding state without interfering with the slats 4 in the folded state. it can.

In the present embodiment, in particular, the shielding portion 27 is rotatably connected to the mounting portion 26 on the rear end side of the mounting portion 26. Thereby, by rotating the shielding part 27 with respect to the attachment part 26, the shielding part 27 can be switched from the shielding state to the non-shielding state and vice versa.

In addition, in the present embodiment, the following effects can be obtained. That is, the shielding part 27 may be in a non-shielding state by rotating to the rear side (opposite to the attachment part 26) with respect to the attachment part 26 in the shield state. In such a case, when there are obstacles such as the ribs of the frame 11 or the window glass 10 on the rear side of the shielding part 27, the obstacles interfere with each other and obstruct the rotation of the shielding part 27. Further, when the shielding part 27 is rotated to the non-shielding state, it may protrude from the frame 11. For this reason, a space is required on the rear side of the shielding part 27. On the other hand, in this embodiment, the shielding part 27 is in a non-shielding state by rotating to the front side (so as to overlap the attaching part 26) with respect to the attaching part 26 in the shielding state. Thus, even when there are obstacles such as the ribs of the frame 11 or the window glass 10 on the rear side of the shielding part 27, the obstacles do not interfere with each other and do not obstruct the rotation of the shielding part 27. Further, when the shielding part 27 is rotated to the non-shielding state, it does not protrude from the frame 11. Therefore, since it is not necessary to provide a space behind the shielding part 27, space saving can be achieved.

In the present embodiment, in particular, the shielding portion 27 includes a locking portion 271 that locks the shielding portion 27 in a non-shielding state. Thereby, the shielding part 27 can be hold | maintained in a non-shielding state. As a result, when the shielding is not performed, it is possible to prevent the shielding portion 27 from unintentionally rotating and being in a shielding state, and reducing the open space inside the frame 11 from being reduced.

In the present embodiment, in particular, the shielding portion 25 includes a lid portion 251 for covering the connection portion 28 between the shielding portion 25 and the shielding portion 27. Thereby, the shielding property in the connection part 28 can be improved, and the solar radiation from the said connection part 28 (leakage of light) can be suppressed.

In addition, in the present embodiment, the following effects can be obtained. That is, for example, when the shielding parts 25 and 27 are made of a material having low light shielding properties, even if the gaps S1 and S2 are shielded by the shielding parts 25 and 27, solar radiation passes through these shielding parts 25 and 27. There is a possibility of entering. In the present embodiment, the shielding portions 25 and 27 are made of a light shielding material. Thereby, the light-shielding property in the shielding parts 25 and 27 can be improved, and the entrance of solar radiation (light leakage) from the gaps S1 and S2 can be prevented.

In this embodiment, in particular, the moving part 23 connects the shielding part 27 and the attaching part 26 so that the shielding part 27 can rotate relative to the attaching part 26 on the rear end side of the attaching part 26. A hinge mechanism 230 is provided. Thereby, the shielding part 27 can be rotated with respect to the attachment part 26 by using the hinge mechanism 230 as a rotation fulcrum, and the switching between the shielding state and the non-shielding state of the shielding part 27 can be performed smoothly.

In the present embodiment, in particular, the plurality of hinge pieces 231 and the plurality of hinge pieces 232 are configured such that the plurality of hinge pieces 231 can rotate with respect to the plurality of hinge pieces 232 about the pin 233 as a rotation fulcrum. And are connected. As a result, the plurality of hinge pieces 231 are rotated in conjunction with the plurality of hinge pieces 232 using the pin 233 as a rotation fulcrum, so that the shielding part 27 is attached to the attachment part 26 using the hinge mechanism 230 as a rotation fulcrum. It can be rotated.

In the present embodiment, in particular, the plurality of hinge pieces 231 and the plurality of hinge pieces 232 are formed by notching. Thereby, a plurality of hinge pieces 231 can be formed continuously with respect to the width direction base end portion of the shielding portion 27, and a plurality of hinge pieces 233 can be formed continuously with respect to the rear end portion of the attachment portion 26. .

A light shielding plate attaching portion 272 to which a light shielding plate 30 made of a metal such as aluminum can be attached is provided. In addition, you may provide a light-shielding plate attaching part in the rear surface of the shielding part 27, or an inside.

The light shielding plate attaching portion 272 is formed as a groove portion that is recessed in the thickness direction of the shielding portion 27 and has a predetermined width along the vertical direction. Engaging portions 273 and 274 that can be engaged with the left end portion and the right end portion of the light shielding plate 30 are provided at the left end portion and the right end portion of the light shielding plate attachment portion 272, respectively. And the light-shielding plate 30 is attached to the light-shielding plate attaching part 272 so that the left end part and the right end part may engage with the engaging parts 273 and 274, respectively.

A light shielding plate may be attached to the attachment portion. In addition, you may provide a light-shielding plate attaching part in the rear surface of the shielding part 25, or an inside.

According to this modification, the light shielding property in the shielding part 27 can be improved, and the entrance of sunlight (light leakage) from the gap S2 can be prevented.

(2) When the shielding part and the attaching part are connected by the link mechanism In the above embodiment, the shielding part 27 and the attaching part 26 are connected by the hinge mechanism 230, but the present invention is not limited to this. For example, you may connect the shielding part 27 and the attaching part 26 with a link mechanism.

As shown in FIGS. 11A, 11 </ b> B, and 11 </ b> C, in the present modification, the moving unit 23 includes a link mechanism 330, and the link mechanism 330 causes the shielding unit 27 to be the rear end portion of the attachment unit 26. The shielding part 27 and the attachment part 26 are connected so as to be rotatable with respect to the attachment part 26 on the side. The link mechanism 330 includes two connecting members 332 and 333 and a link member 331.

The connecting member 332 is slidable in the groove portion 275 while fitting into the groove portion 275 provided in an appropriate part of the shielding portion 27. The connecting member 333 is slidable in the groove portion 265 while being fitted in a groove portion 265 provided in an appropriate part of the attachment portion 26. One end side of the link member 331 is connected to the connecting member 332, and the other end side is connected to the connecting member 333, thereby connecting the connecting member 332 and the connecting member 333.

As described above, the connecting member 332 and the connecting member 333 are connected by the link member 331, the connecting member 332 can slide in the groove portion 275, and the connecting member 333 can slide in the groove portion 265. The portion 27 is rotatable with respect to the attachment portion 26 on the rear end side of the attachment portion 26.

That is, when the shielding portion 27 is in the shielding state, the link member 331 is positioned so that the connecting members 332 and 333 are positioned at appropriate positions (for example, one end) of the groove portions 275 and 265 (FIG. 11A). reference). Then, when the shielding part 27 is in the shielding state, the link member 331 moves so that the connecting members 332 and 333 slide in the grooves 275 and 265 in an appropriate direction (for example, the other end side). The part 27 can turn to the front side with respect to the attachment part 26 on the rear end side of the attachment part 26 to be in an unshielded state (see FIGS. 11B and 11C).

Note that the configuration and operation of the link mechanism 330 described above are merely examples, and configurations and operations other than those described above may be used. For example, the shape of the groove portions 275 and 265, the position and moving direction of the connecting members 332 and 333 in the groove portions 275 and 265, the movement mode of the link member 331, and the like are limited to the modes shown in FIGS. However, other modes may be used.

According to this modification, the shielding part 27 can be rotated with respect to the attachment part 26 via the link mechanism 330, and the switching between the shielding state and the non-shielding state of the shielding part 27 can be performed smoothly. .

(3) When the shielding part and the attaching part are connected by the expansion / contraction mechanism In the above embodiment, the shielding part 27 and the attaching part 26 are connected by the hinge mechanism 230, but the present invention is not limited to this. For example, you may connect the shielding part 27 and the attaching part 26 with an expansion-contraction mechanism.

As shown in FIGS. 12A and 12B, in this modification, the moving unit 23 has an expansion / contraction mechanism 430, and the expansion / contraction mechanism 430 enables the shielding unit 27 to move with respect to the attachment unit 26. Further, the shielding part 27 and the attaching part 26 are connected. The expansion / contraction mechanism 430 is formed as an expandable / contractible bellows member.

That is, when the shielding part 27 is in the shielding state, the telescopic mechanism 430 is contracted (see FIG. 12A). And when the shielding part 27 is in the shielding state, the expansion / contraction mechanism 430 extends, so that the shielding part 27 moves so as to be close to the attachment part 26 and can enter the non-shielding state ( (Refer FIG.12 (b)).

It should be noted that the configuration and operation of the telescopic mechanism 430 described above are merely examples, and configurations and operations other than those described above may be used. For example, the expansion / contraction mechanism may be configured integrally with at least one of the attachment portion 26 and the shielding portion 27. Or you may comprise shielding part 27 itself as an expansion-contraction mechanism.

According to this modification, the shielding part 27 can be moved with respect to the attachment part 26 via the telescopic mechanism 430, and the switching between the shielding state and the non-shielding state of the shielding part 27 can be performed smoothly.

(4) When two shielding portions are pivotably connected to the attachment portion In the above embodiment, one shielding portion 27 is pivotally connected to the attachment portion 26. However, the present invention is limited to this. It is not a thing. For example, you may connect two shielding parts with respect to the attaching part 26 so that rotation is possible.

As shown in FIGS. 13 (a) and 13 (b), in this modification, the mounting portion 26 ′ (second mounting portion, third mounting portion) mounted on the inner surface of the right edge portion 11c has two shielding portions 27a. , 27b (second shielding part, third shielding part) are rotatably connected to the mounting part 26 '.

The attachment portion 26 'allows the shielding portion 27a in the shielding state to shield the gap S2 between the slat 4 and the window glass 10 (outside of the slat 4), and the shielding portion 27b in the shielding state slats. 4 on the side opposite to the window glass 10 (inner side of the slat 4) so that the gap S2 can be shielded. In addition, you may attach attachment part 26 'so that the positional relationship of the shielding part 27a and the shielding part 27b may become reverse.

When the shielding part 27a and the shielding part 27b shield the gap S2, the width direction of the shielding part 27a is substantially perpendicular to the width direction of the mounting part 26 '(the state shown in FIG. 13A), and the shielding part 27a and the shielding part 27b are shielded. When not performed, the rear end side of the attachment portion 26 'and the non-shielding state (the state shown in FIG. 13B) are substantially parallel to the width direction of the attachment portion 26', respectively. On the front end portion (width direction end portion) side, it is rotatably connected to the attachment portion 26 ′. Accordingly, the moving portion 23 'is generally U-shaped in plan view when the shielding portions 27a and 27b are in the shielding state.

Specifically, the shielding part 27a is turned to the front side (attachment part 26 'side) so as to be close to the attachment part 26' in the shielded state, thereby becoming a non-shielded state. By rotating to the left so as to be separated from the portion 26 ′, it is connected to the mounting portion 26 ′ so as to be in a shielding state. Further, the shielding part 27b is turned to the rear side (attachment part 26 'side) so as to be close to the attachment part 26' in the shielded state, thereby becoming a non-shielded state. By rotating to the left so as to be separated from ′, it is connected to the mounting portion 26 ′ so as to be in a shielding state.

In the present modification, the shielding portions 27a and 27b can shield the gap S2 when each is in a shielding state, and do not overlap each other when they are in a non-shielding state. It is a dimension. In this example, the widthwise dimension of the shielding part 27a is longer than the widthwise dimension of the shielding part 27b, and the sum of the widthwise dimension of the shielding part 27a and the widthwise dimension of the shielding part 27b is the width of the mounting part 26 '. It is almost the same as the direction dimension. The width dimension of the shielding portions 27a and 27b is such that the gap S2 can be shielded when each is in the shielding state, and the width is such that they do not overlap each other when they are in the non-shielding state. The relationship is not particularly limited as long as the dimension is a dimension in the direction, and for example, a relation in which the dimension in the width direction is substantially the same may be used.

Further, for example, as shown in FIG. 14, the shielding portions 27a and 27b can shield the gap S2 when each is in a shielding state, and overlap each other when they are in a non-shielding state. It is good also as a width direction dimension. In the example shown in FIG. 14, the width direction dimension of the shielding part 27a and the width direction dimension of the shielding part 27b are substantially equal to the width direction dimension of the attachment part 26 ', respectively.

Also in this modification, the same effect as the above embodiment can be obtained.

The shielding part 47 can shield the gap between the bottom rail 5 at the lower end of the slat 4 supported suspended at a predetermined height and the part to which the attachment part 46 is attached on the inner surface of the lower edge part 11d. . That is, when shielding the gap, the shielding portion 47 is in a shielding state (state shown in FIG. 15A) whose width direction is substantially perpendicular to the width direction of the mounting portion 46, and when shielding is not performed. Is attached on the rear end portion (end portion in the width direction) side of the attachment portion 46 so that the width direction thereof becomes a non-shielding state (the state of FIG. 15B) substantially parallel to the width direction of the attachment portion 46. It is connected to the portion 46 so as to be movable.

Specifically, the shielding part 47 becomes a non-shielding state by rotating to the front side (attachment part 46 side) so as to be close to the attachment part 46 in the shielding state, and the attachment part 46 in the non-shielding state. It is connected with the attachment part 46 so that it may be in a shielding state by rotating upward so that it may separate.

Is attached on the rear end portion (width direction end portion) side of the attachment portion 56 so that the width direction thereof is in a non-shielding state (state of FIG. 16B) substantially parallel to the width direction of the attachment portion 56. It is connected to the portion 56 so as to be movable.

Specifically, the shielding part 57 is turned to the front side (attachment part 56 side) so as to be close to the attachment part 56 in the shielded state, thereby becoming a non-shielded state. It is connected with the attachment part 56 so that it may be in a shielding state by rotating upward so that it may separate.

Also in this modification, the same effect as the above embodiment can be obtained. In this modification, the left end and the right end of the lateral guide portion installed on the lower edge portion 11d may be non-moving portions, and the space between these two non-moving portions may be a moving portion. In this case, interference with the vertical guide parts 21 and 21 in the horizontal guide part can be suppressed.

In the fourth modified example, two shielding portions 27a and 27b are provided apart from each other in the front-rear direction with respect to the attachment portion 26 '. However, the present invention is not limited to this. For example, when the horizontal blind 1 is replaced with a roll screen, two shielding portions may be provided at an interval that sandwiches the range of movement in the front-rear direction of the screen that functions as a shielding member. Moreover, although the operator performed the opening / closing operation | movement manually by the operator in all the shielding parts shown in the said embodiment or each modification, it is not limited to this. For example, at least one of the two shielding portions may be provided so as to be automatically rotatable.

Here, in the roll screen, a screen R (for example, a cloth material) is wound in a roll shape on a winding shaft that is rotatably provided inside the head box 2, and the screen R is wound around the winding shaft. The entire screen R is moved up and down by taking out and pulling out (not shown). And since the outer peripheral diameter of the roll changes with the winding amount of the screen R by a winding shaft, the drooping position of the screen R in the front-back direction changes accordingly. In the present modification, it is assumed that the screen R is located at the foremost position when it is pulled out most and is located at the rearmost position when the screen R is wound up most. The two shielding portions 27c and 27d are provided at an interval between the screen R in the vicinity of the moving range M in the front-rear direction (see FIGS. 19A and 19B).

With the above configuration, in the moving part 23, the two shielding parts 27c and 27d are provided so as to sandwich the gap between the screen R and the left edge part 11b in the front-rear direction. For this reason, even with respect to reflected light and radiation light leaking from the gap in the front-rear direction between the rear-side shielding part 27c and the screen R, the front-side shielding part 27d can further shield the solar radiation. In addition, the two shielding portions 27c and 27d are provided in a parallel arrangement with the moving range M in the front-rear direction of the screen R accompanying the change in the vertical droop length of the screen R. 27d can more reliably shield the reflected light and the radiated light at the closest position without touching the screen R in any hanging state. In addition, since the two shielding portions 27c and 27d are provided so as to be rotatable in the same direction, the overall width in the front-rear direction when both are turned to the attachment portion 26 ″ to be in the non-shielding state is reduced. Thus, the installation area can be saved.

In the present modification, the end surface of the lower end of the shielding portion side hinge piece portion 232d included in the front side shielding portion 27d and the end surface of the upper end portion of the attachment portion side hinge piece portion 231d included in the attachment portion 26 ″ are respectively the pins 233. The planes 236 and 237 form a predetermined inclination angle (solid angle) with respect to the axial direction, and these inclination planes 236 and 237 are parallel to each other when the shielding portion 27d is in a non-shielding state. 17, the pin 233 is not shown in FIG.

Further, the shielding part 27d is provided with a locking part 278 for locking the shielding part 27d in a shielded state. The latching | locking part 278 is formed as a protrusion part protruded along the up-down direction from the outer peripheral surface of the said shielding part side hinge piece part 232d. The locking portion 278 is locked at the end of the mounting portion 26 ″ when the shielding portion 27d is rotated rearward with respect to the mounting portion 26 ″ to be in a shielding state, thereby blocking the shielding portion 278. The shielding part 27d can be locked in a shielded state by suppressing the forward rotation of the part 27d. The locking portion 278 is not limited to the protruding portion protruding in the vertical direction from the outer peripheral surface of the shielding portion side hinge piece portion 232d as described above, and the shielding portion 27d is locked in the shielding state. Anything is possible as long as it is possible. For example, a separate bracket may be provided so as to come into contact with the upper end of the shielding part 27d, and a protrusion for locking the shielding part 27d so as to be maintained in a shielding state may be provided on the lower surface of the bracket (particularly not shown). )

By configuring as described above, a part of the weight of the shielding portion 27d is added to the inclined plane 236 at the lower end of the shielding portion side hinge piece 232d, and this is added to the inclined plane 237 at the upper end of the attachment portion side hinge piece 231d. Will receive. Since these two inclined planes 236 and 237 are formed with a predetermined inclination angle (solid angle) with respect to the axial direction of the pin 233, the rotation angle of the shielding portion 27d with respect to the attachment portion 26 ″ is large. In some cases, the support of the shielding portion side hinge piece portion 232d by the attachment portion side hinge piece portion 231d becomes unstable, and when the shielding portion 27d is not restrained around the axis of the pin 233, the entire shielding portion 27d is provided. Due to its own weight, a component force is generated around the axis, and the shielding portion 27d operates so as to automatically rotate in a direction in which the support is stabilized.By using this behavior, the inclination angles of the inclined planes 236 and 237 are appropriately set. By setting, it is possible to perform an automatic turning operation when the shielding portion 27d is released from the restraint such as locking, and it is possible to automatically switch between the shielding state and the non-shielding state.

In this modification, as described above, when the shielding portion 27d is in the non-shielding state, the two inclined planes 236 and 237 are formed at an inclination angle that is parallel to each other. For this reason, as shown in FIG. 20A, when the shielding part 27d is in the shielding state (open state), the entire shielding part 27d is lifted so that the two inclined planes 236 and 237 are lined up with each other. Contact and become unstable support. Further, as shown in FIG. 20B, when the shielding part 27d is in a non-shielding state (closed state), the inclined flat surfaces 236 and 237 are in surface contact with each other and the shielding part by the attachment-side hinge piece 231d. The support of the side hinge piece 232d is most stable. For this reason, for example, when the shielding part 27d in the shielding state is released from the restraint such as the locking by the locking part 278 described above, the entire shielding part 27d is lowered by its own weight and the inclined planes 236 and 237 are in contact with each other. The support can be automatically rotated in a direction in which the support is stable, that is, in a rotation direction in which the support is unshielded.

In the present modification, as described above, the two shielding portions 27c and 27d are provided so as to sandwich the gap between the screen R and the left edge portion 11b in the front-rear direction, and in particular, the front-side shielding portion 27d is the screen. It is provided at a position close to the screen R when R is pulled out most (longest hanging length is longest). For this reason, when the operator rolls up and pulls up the screen R, a weight bar (equivalent to the bottom rail 5) provided at the lower end of the screen R comes into contact with the lower end of the shielding portion 27d, and the momentum due to the contact. Thus, it can be released from the restraint around the axis by the locking portion 278. As a result, the operator can automatically rotate the shielding portion 27d in the shielding state to the non-shielding state only by performing the winding up operation of the screen R.

Further, a weight portion 279 having a thickness dimension larger than that of other portions is provided at the outer peripheral side end portion of the shielding portion 27d of this modification. As described above, since the mass is high in the weight portion 279 located at the outer peripheral end portion, the moment of inertia around the axis of the shielding portion 27d is increased, and the above-described self-rotation operation can be performed smoothly. In addition, since the shielding portion 27d includes the weight portion 279, the shielding portion 27d is likely to come into contact with the weight bar (equivalent to the bottom rail 5) as much as the thickness dimension is large. For this reason, the release from the locking by the locking portion 278 and the start of the automatic rotation operation can be performed more reliably. Further, since the thickness of the weight portion 279 is large, it is possible to more reliably shield reflected light and radiated light leaking from a gap in the front-rear direction between the rear shielding portion 27c and the screen R.

In addition, in the combination in which the attachment portion side hinge piece portion 231d is located above and the shielding portion side hinge piece portion 232d is located below, each hinge piece portion is configured so as to be able to move up and down along with its own weight rotation operation of the shielding portion 27d. An appropriate gap is provided between 231d and 232d. Further, in the present modification, an example in which two shielding portions 27c and 27d at close intervals in the moving unit 23 are provided and the shielding portion 27d has a self-weight rotation function is shown, but the present invention is not limited thereto. It is not a thing. For example, in the non-moving part 22, two shielding parts 25 that are close to each other may be provided, or the shielding part 27 c may have a self-weight rotation function.

Further, in the above modification, the support end surfaces of the hinge pieces 231d and 232d are formed in a planar shape, but the present invention is not limited to this. For example, as shown in FIG. 21 corresponding to FIG. 20, the support end surfaces of the hinge pieces 231d and 232d are formed in parallel with each other by spiral curved surfaces 236a and 237a with respect to the central axis of the pin 233, respectively. May be.

Thus, by forming the support end surfaces of the hinge piece portions 231d and 232d with spiral curved surfaces 236a and 237a (parallel to each other) having an appropriate inclination angle, the shield portion 27d has a (depending on its rotation angle). 1) A component force that automatically rotates in the direction of either opening or closing the rotation angle is always generated by its own weight. For this reason, by setting the inclination angle to be positive or negative, for example, the shielding portion 27d can be automatically rotated in the rotation direction from the shielding state to the non-shielding state, or in the opposite rotation direction.

(8) Others In the above embodiment, the upper end of the vertical guide portion 21 installed on the left edge portion 11b and the right edge portion 11C is configured by the non-moving portion 22, and the lower portion of the non-moving portion 22 is configured by the moving portion 23. However, the present invention is not limited to this. For example, you may install the vertical guide part comprised by a moving part (without a non-moving part) with respect to the left edge part 11b and the right edge part 11C. In this case, the shielding part (third moving part) of the moving part (second moving part) rotates to the front side (attaching part side) so as to be close to the attaching part (third moving part) in the shielding state. Thus, the non-shielding state is established, and in the non-shielding state, it is preferably connected to the attachment portion so as to be in the shielding state by rotating to the left so as to be separated from the attachment portion. Also in this case, the same effect as the above embodiment can be obtained.

In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

Other than that, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
