Description

The present invention relates to a screen device applied to light-shielding and dimming means such as curtains and blinds, screen doors, partitions and the like.

Conventionally, in this type of screen device, generally, a screen that can be freely deployed and stored and at least one of the three axes that are orthogonal to each other in the deploying and storing direction of the screen are slidable in the X-axis direction. The first stile, which is long and hollow in the Z-axis direction and has one end fixed in the X-axis direction of the screen, and the second stile in which the other end in the X-axis direction of the screen is fixed. When a pair of stiles and a slidable stile are slid in one direction in the X-axis direction, the slidable stile is pulled out from the inside of the slidable stile in the other direction in the X-axis direction, and the slidable stile is slid in the other direction in the X-axis direction. When the stile is stored inside the slidable stile, it has a free end at one end, and the part drawn out from the inside of the slidable stile is between one end in the Z-axis direction of the pair of stiles and the Z-axis. A tension that connects the first guide and the second guide, which extend linearly in the X-axis direction between the other ends of the direction, and the free ends of the first guide and the second guide, which are provided inside the slidable stile. It is equipped with a member.

Further, in the screen device, a first guide is formed by connecting a plurality of first guide units, and each first guide unit is Y when the first guide is pulled out from the inside of a slidable stile. A pair of side walls arranged so as to face each other in the axial direction and a bottom wall connecting both side walls are provided. In the first guide, one of the two adjacent first guide units is the other. It is pivotally supported by a first guide unit, which allows the first guide to bend in the Z-axis direction while maintaining linearity in the X-axis direction and to be pulled out from the inside of the slideable stile of the first guide. It is known that one end in the Z-axis direction of the unfolding screen is inserted between the side walls of each first guide unit in the section (see, for example, Patent Document 1).

In the screen device described in Patent Document 1, both side walls are formed at one end in the X-axis direction of both side walls of each first guide unit, which corresponds to one end in the Z-axis direction of the first guide drawn from a slidable frame. A pair of pins facing inward in the opposite direction are provided, a pair of openings are opened at the other end in the X-axis direction, and two first guide units are placed in each opening of one first guide unit with the other. Each pin of the first guide unit is loosely fitted to be connected, and both pins form a pivot.

Further, in the screen device described in Patent Document 1, rigid protrusions are projected inward in the opposite direction of both side walls on both side walls of each first guide unit on the side where the pins are provided. In the first guide, the rigid protrusion extends along the virtual line in the plane including the virtual line connecting the center of the pivot of each first guide unit in the connecting direction of the first guide unit. Then, when the first guide is pulled out to the other in the X-axis direction with the slide of one of the slideable stiles in the X-axis direction, the rigid protrusions are provided on both sides of each first guide unit in the pulled out portion of the first guide. Even if the expanded screen is pierced by the other end of the screen inserted between the walls in the Z-axis direction and receives an external force such as wind pressure, one end of the screen in the Z-axis direction comes off from the pulled-out part of the first guide. Hold it so that it does not come off.

However, although it is a rigid protrusion, each first guide unit is generally an integrally molded product made of resin, and as the screen is deployed and stored, it repeatedly pierces and comes off from one end in the Z-axis direction of the screen. , Rigid protrusions have problems such as being bent and deformed, or being broken and damaged. Further, the type of screen is generally changed depending on the use and installation location of the screen device. Therefore, if the molding material of each of the first guide units has a higher strength than the screen, one end of the screen in the Z-axis direction may be damaged when the rigid protrusions pierce the screen. In order to prevent the screen from being damaged, in the case of the screen device described in Patent Document 1, it is necessary to manufacture a plurality of types of the first guide unit using a material corresponding to the type of the screen. As a result, there are multiple types of first guides.

In the first guide 6, two adjacent first guide units 63, 63 are placed inside the right end portions of one of the first guide units 63 in the opposite direction of both side walls 63a, 63a, and both sides of the other first guide unit 63. The left ends of the walls 63a and 63a are inserted, and each pin 63c of the other first guide unit 63 is loosely fitted into each opening 63d of the one first guide unit 63 to be connected. At this time, both pins 63c and 63c form an axis. By repeating such connection, the first guide 6 is formed. The pivotal range of the two adjacent first guide units 63, 63 is the right end of the lower end of both side walls 63a, 63a of one first guide unit 63 and the side walls 63a, 63a of the other first guide unit 63. From the position where the left end of the lower end comes into contact, the first pieces 63e of the side walls 63a and 63a of one first guide unit 63 and the first side walls 63a and 63a of the other first guide unit 63 are formed. It is up to the position where each mountain portion 63f of the recess portion 63a _{1 comes into contact with each other.} The pivot range of each first guide unit 63 is the same, and due to the pivot of each first guide unit 63 within the pivot range, the first guide 6 is moved to the first stile 2 as shown in FIG. When it is stored inside the first stile 2, it bends toward the upper end of the first stile 2, and when it is pulled out from the inside of the first stile 2, it returns to its original state toward the right.

When the first guide 6 is pulled out from the inside of the first stile 2, each of the two adjacent first guide units formed on both side walls 63a and 63a of the pivoting first guide unit 63. The second recessed portion 63a ₃ is inserted inside the other first guide unit 63 on both side walls 63a, 63a in the opposite direction. Therefore, in the portion 62 drawn out from the inside of the first stile 2 of the first guide 6, the outer surfaces in the opposite direction at the lower ends of the side walls 63a and 63a of each first unit 63 are arranged flush with each other. Further, as described above, since the length of each pin 63c _{is the same as the recess allowance of the first recessed portion 63a 1} , the outer surfaces of the side walls 63a and 63a of each pin 63c in the opposite direction are the side walls 63a, It is arranged flush with the outer surface in the opposite direction at the upper end portion of 63a.

Further, each of the first guide units 63 is provided with rail portions 63g on the inner portions of the side walls 63a and 63a in the opposite direction, and each rail portion 63g is first centered on the pivot of the first guide unit 63. It extends along the virtual line VL in the plane including the virtual line VL connected in the connecting direction of the guide unit 63. Further, support pieces 63h projecting inward in the opposite direction of the side walls 63a, 63a are provided on the upper end edges of the side walls 63a, 63a, which are separated from the bottom wall 63b above the rail portion 63g. Each support piece 63h is arranged so as to face each rail portion 63g of each side wall 63a on the side where each support piece 63h is provided in the vertical direction, and forms a hollow storage portion 63i with each rail portion 63g. (Fig. 4 (d)). Specifically, each rail portion 6g has a length from the left end of each first guide unit 63 to the _{lower left end of the first notch 63a 2.} On the other hand, each support piece 63h extends in the left-right direction except for the left end portion of each first guide unit 63. Further, the front shape of each support piece 63h is L-shaped, and the locking portion 63h ₁ that hangs parallel to each side wall 63a and the side walls 63a and 63a descend inward in the opposite direction toward the rail portion 63g. It is composed of an inclined portion 63h _{2 extending on a gradient.}

Each rail portion 63g functions as a guide when attaching and detaching the screen retaining member 9 to and from the first guide 6. With reference to FIGS. 5A and 5B, the screen retaining member 9 has a distance from the long base 91 which is flexible in the pivotal direction of each of the first guide units 63 of the first guide 6. It is composed of a large number of needle-shaped portions 92 attached to the base portion 91. The screen retaining member 9 inserts the base 91 into each storage portion 63i of each first guide unit 63 from either the left or right end of the first guide 6, thereby inserting the base portion 91 into the side walls 63a of each first guide unit 63. , 63a is mounted inside in the opposite direction. Each rail portion 63g guides the insertion of the base portion 91 into the storage portion 63i when the screen retaining member 9 is attached. In the mounted state of the screen retaining member 9, the base 91 is supported between each rail portion 63g and each support piece 63h, and all the needle-shaped portions 92 are both side walls 63a and 63a of each first guide unit 63. Protrudes inward in the opposite direction. Further, the screen retaining member 9 is guided by each rail portion 63g by pulling out the base portion 91 from the inside of each storage portion 63i of each first guide unit 63 from either the left or right end of the first guide. It can be removed from the guide 6.

Specifically, the support piece base 91 by the locking portion 63h ₁ of 63h of the first guide unit 63 is locked by the inclined portion 63h _2, all of the needle-like portion 92, downward slope of the inclined portion 63h ₂ It is inclined toward the bottom wall 63b side along the above (FIG. 3 (b)). Due to this inclination of all the needle-shaped portions 92, in the first guide 6, between the tips of the needle-shaped portions 92 of the two screen retaining members 9 mounted on the side walls 63a and 63a of each first guide unit 63 in the protruding direction. A gap in the Y-axis direction shown in FIG. 2 is formed.

As described above, the base 91 of the screen retaining member 9 is flexible in the pivotal direction of each of the first guide units 63 of the first guide 6, so that the first stile 2 shown in FIG. 1 is the upper end. As shown in FIG. 6, the screen retaining member 9 also bends in the same direction when bending toward. Further, as described above, since each rail portion 63g extends along the virtual line VL in the plane including the virtual line VL connecting the centers of the pivots of each first guide unit 63 in the connecting direction, FIG. As shown in a), the base 91 of each screen retaining member 9 mounted inside the side walls 63a and 63a of each first guide unit 63 in the opposite direction is parallel to the virtual line VL in the plane including the virtual line VL. Be placed. By arranging the base 91 in parallel with the virtual line VL in this way, the pivot of each first guide unit 63, that is, the bending of the first guide 6 is smoothly realized. Further, since the pivot is located at the upper end of the first guide unit 63, the pivot is arranged upward away from the lower end of the opening in which the screen device SD is installed. Therefore, the pivot is not easily affected by dust, sand, mud, etc. that tend to collect at the lower end of the opening, and in combination with the smooth bending of the first guide 6, the user can close the first stile 2. It is light and stable. Similarly, since the base 91 of the screen retaining member 9 easily returns to the original state from the bent state, the return to the original state when the first guide 6 is pulled out from the inside of the first stile 2 can be smoothly performed. It will be realized. Therefore, the opening operation of the first stile 2 is also performed lightly and stably.

Then, on both side walls 63a and 63a of each first guide unit 63, they extend in the same direction as the portion 62 of the first guide 6 which is pulled out from the inside of the first stile 2 and extends in the left-right direction, and is recessed inward in the opposite direction. A recess 63j is provided. At the left end of the side walls 63a, 63a provided with the recess 63j, there is a third recess that is recessed inward in the opposite direction of the side walls 63a, 63a, similar to _{the first recess 63a 1} and the second recess 63a _3. Part 63a ₄ is formed. The third recessed portion 63a ₄ is located between the first recessed portion 63a ₁ and the second recessed portion 63a _{3 on each side wall 63a.} Further, the inner surfaces of the right end portions of the side walls 63a and 63a provided with the recesses 63j in the opposite direction are notched to form the second notched portion 63a ₅ (FIGS. 4 (b) and (c)).

When the first guide 6 is pulled out from the inside of the first stile 2 and each first guide unit 63 is pivoted, the second notch 63a ₅ of the pivoting first guide unit 63 has already finished pivoting. It is polymerized in the third recessed portion 63a _{4 of the adjacent first guide unit 63.} By this polymerization and the contact between the right ends of the lower ends of the both side walls 63a and 63a of the pivoting first guide unit 63 and the left ends of the side walls 63a and 63a of the first guide unit 63 that have already been pivoted, the first The linearity of the portion 62 of the first guide 6 drawn from the inside of the 1st frame 2 is maintained. Further, the inner surfaces of the side walls 63a and 63a provided with the recesses 63j in the opposite direction are arranged flush with each other.

In the side walls 63a and 63a of each of the first guide units 63, as shown in FIGS. 3 (b) and 4 (c) and (d), the inner surfaces of the lower ends of _{the second recessed portions 63a 3 in the opposite direction are formed.} A third notch 63a ₆ is formed by being cut out. The notch allowance of each of the third notch portions 63a ₆ is reduced from the left end to the right end of each of the second recessed portions 63a _3. Further, a guided piece 63k is provided which continuously protrudes inward in the opposite direction of the side walls 63a and 63a from the right end of each of the third notch 63a _6. The right end of each guided piece 63k is located below the right end of the bottom wall 63b. When the first guide 6 is pulled out from the inside of the first stile 2, both the guided pieces 63k and 63k engage with the one side end portion and the other side end portion of the lower rail 5 shown in FIG. 1 in the Y-axis direction. Then, each of the first guide units 63 in the pulled-out portion 62 of the first guide 6 is suppressed from being separated from the lower rail 5. On the other hand, when the first guide 6 is housed inside the first stile 2, each of the third cutout portions 63a ₆ includes each guided piece 63k, the one-sided end portion of the lower rail 5 in the Y-axis direction, and the other side. The engagement with each of the ends is smoothly disengaged, facilitating disengagement from the lower rail 5 of each first guide unit 63. As a result, the sliding of the first stile 2 in the left-right direction is realized more smoothly.

Returning to FIG. 1, the first guide unit 63 located at the right end of the first guide 6 is fixed to the lower end of the second stile 3, and the right end of the first guide 6 is a fixed end. Further, the free end 61 of the first guide 6 is always housed inside the first stile 2. Specifically, the free end 61 is located at the upper end of the adjuster 10 that moves up and down in the longitudinal direction of the first stile 2. The adjuster 10 is connected to a first guide unit 63 located at the upper end when the first guide 6 is housed inside the first stile 2. The adjuster 10 has a built-in rod-shaped weight 101 that is long in the vertical direction. The gravity acting on the weight 101 acts on the portion of the first guide 6 housed inside the first stile 2, and when the first stile 2 is slid to the left, the coil spring 31a built in the roller pipe 31 The first guide 6 assists the first guide 6 to be smoothly pulled out to the right from the inside of the first stile 2 against the elastic force, and gives a feeling of lightness and stability by the closing operation of the user. Further, the gravity acting on the weight 101 is stored inside the first stile 2 of the first guide 6 when the first stile 2 is slid to the right and the screen 1 is stored inside the second stile 3. The screen 1 is assisted so that the roller pipe 31 of the screen 1 is not suddenly wound around the outer peripheral surface due to the release of the elastic force accumulated in the coil spring 31a.

At the lower end of the first stile 2, a pair of inner side surfaces (not shown) facing in the Y-axis direction shown in FIG. 2 are provided with curved protrusions 11 that are curved with a predetermined curvature. The curved protrusion 11 is inserted into the recess 63j of each first guide unit 63 to guide the storage and withdrawal of the first guide 6 into the first stile 2. That is, the curved protrusion 11 has a predetermined curvature so that the first guide 6 can be bent upward smoothly inside the first stile 2 and returned to the right inside the first stile 2. It is curved at. Therefore, smoother storage and withdrawal of the first guide 6 into the first stile 2 is realized.

In the above screen device SD, when the first guide 6 is pulled out to the right from the inside of the lower end portion of the first stile 2 with the slide to the left of the first stile 2, the lower end portion of the screen 1 is the first. It is inserted between the side walls 63a and 63a of each of the first guide units 63 in the pulled-out portion 62 of the guide 6. Specifically, the lower end of the screen 1 is a needle shown in FIGS. 2 and 3 (a) and 3 (b) of two screen retaining members 9 mounted on both side walls 63a and 63a of each first guide unit 63. It is inserted into the gap between the tip of the shape portion 92 in the protruding direction. At this time, each needle-shaped portion 92 of the screen retaining member 9 pierces the inserted portion of the screen 1, and the screen 1 cannot be removed from the pulled-out portion 62 of the first guide 6. Further, when the first guide 6 is housed inside the first stile 2 along with the slide to the right of the first stile 2, the needle-shaped portion 92 of each screen retaining member 9 comes off from the portion pierced by the screen 1. It comes off. As described above, in the screen device SD, the screen retaining member 9 is detachably mounted inside the side walls 63a and 63a of each of the first guide units 63 of the first guide 6 in the opposite direction, so that the type of screen 1 is used. A plurality of types of screen retaining members 9 having a large number of needle-shaped portions 92 attached to the base 91 can be prepared in advance. Then, an appropriate one can be selected from them and attached to the side walls 63a and 63a of each of the first guide units 63 of the first guide 6, and the screen can be repeatedly expanded and stored. Damage to the lower end of 1 can be suppressed. Further, it is not necessary to manufacture the first guide unit 63 for each type of screen 1, and the first guide 6 can be formed only by one type of first guide unit 63.

An integrally molded product made of hard resin can be adopted for each first guide unit 63. For the screen 1, a cloth or a net woven with resin fibers can be adopted in consideration of weight reduction. For the base 91 of the screen retaining member 9, one made of soft resin, one made of light metal such as aluminum, or the like can be adopted. The needle-shaped portion 92 can be formed from an appropriate material corresponding to the type of screen 1. Further, the size of each needle-shaped portion 92 and the interval between each needle-shaped portion 92 can be appropriately set according to the type of the screen 1. For example, when the screen 1 is knitted or meshed, the size of each needle-shaped portion 92 is set to a size that allows it to enter the stitch or mesh, and the spacing between the needle-shaped portions 92 is the same as between the stitches or mesh. Can be evenly spaced. Further, the curved protrusion 11 can be formed of a material in which the first guide unit 63 is not easily worn even by repeatedly inserting the first guide unit 63 into the recess 63j.

Further, as the second guide 7 included in the screen device SD, the conventional one can be adopted. Similar to the first guide 6, the conventional one is also formed by connecting a plurality of second guide units 73. With reference to FIG. 7, each of the second guide units 73 has a pair of side walls 73a and 73a arranged so as to face each other in the Y-axis direction when the second guide 7 is pulled out from the inside of the first stile 2, and both sides thereof. A bottom wall 73b connecting the walls 73a and 73a is provided. Further, in the second guide 7, one of the two adjacent second guide units 73 is pivotally supported by the other second guide unit 73, and the first stile 2 of the second guide 7 is provided. The upper end of the screen 1 to be developed may be inserted between the side walls 73a and 73a of each of the second guide units 73 in the portion 72 drawn out from the inside of the screen 1. Like the first guide 6, the second guide 7 also has a right end fixed to the second stile 3 to be a fixed end.

In the screen device SD, the first guide 6 and the second guide 7 housed inside the first stile 2 are housed in different areas inside the first stile 2. That is, each of the pair of inner side surfaces of the first stile 2 facing the Y-axis direction extends in the longitudinal direction of the first stile 2, except for the upper and lower ends of the first stile 2, and is within the opposite directions of both inner surfaces. A guide piece 21 projecting toward the direction is provided. The inside of the first stile 2 is divided into a first storage portion 22 for storing the first guide 6 and a second storage portion 23 for storing the second guide 7 by both guide pieces 21. The first storage unit 22 is located on the inner left side of the first stile 2, and the second storage unit 23 is located on the inner right side of the first stile 2. By dividing the storage area of the first guide 6 and the second guide 7 into the first storage portion 22 and the second storage portion 23 in this way, the first guide 6 and the first guide 6 and the second guide are stored inside the first stile 2. Since the two guides 7 do not collide with each other and can pass each other inside the first stile 2, the total length of the first guide 6 and the second guide 7 is set in the left-right direction of the opening in which the screen device SD is installed. It can be made to correspond to the size of. Further, the needle-shaped portion 92 of the screen retaining member 9 mounted on the opposite inner side of the side wall 63a of each of the first guide units 63 in the first guide 6 is not damaged by the second guide 7, and the second guide 7 is not damaged. No structural restrictions are imposed on the second guide unit 73 forming the above.

The protruding ends of both guide pieces 21 and 21 are arranged apart from each other in the Y-axis direction to guide the raising and lowering of the adjuster 10 of the first guide 6, and the second guide 7 is inside the second storage portion 23. Guides the elevating and lowering of the guided member 12 which is connected to the second guide unit 73 located at the lower end of the second guide 7 and forms the free end 71 of the second guide 7. The free end 71 of the second guide 7 is located at the lower end of the guided member 12.

In this way, when the first guide 6 and the second guide 7 are stored in the first storage unit 22 and the second storage unit 23, which are different areas, inside the first stile 2, respectively, the first The stile 2 has a relatively large founding dimension (dimension in the left-right direction). In consideration of this, as shown in FIG. 1, the second guide unit 73 has the side walls 73a, 73a of the second guide unit 73 in the portion 72 pulled out from the second storage portion 23 of the first stile 2. It is desirable to adopt a dimension whose vertical dimension is shorter than the vertical dimension of the side walls 63a, 63a of the first guide unit 63 in the portion 62 pulled out from the first storage portion 22 of the first stile 2. In this case, if it is difficult to provide the second guide 7 with the screen retaining member 9 to be mounted on the first guide 6, the upper rail 4 is included in the pair of the upper rails 4 facing each other in the Y-axis direction. A screen retaining member 13 that is long in the left-right direction can be attached to each of the side surfaces via a support piece or the like. The screen retaining member 13 may have the same configuration as the screen retaining member 9, for example. In this case, each needle-shaped portion of the screen retaining member 13 pierces the unfolding screen 1, and the unfolded screen 1 is displayed. It is possible to prevent the upper rail 4 from coming off even if it receives an external force such as wind pressure. Further, damage to the upper end portion of the screen 1 can be suppressed by repeating the expansion and storage of the screen 1.

Further, in the screen device SD, a bending guide 14 having a curved surface 141 that curves with a predetermined curvature is provided at the upper end portion of the second accommodating portion 23 of the first stile 2. The curved surface 141 of the bending guide 14 is in contact with the bottom wall 73b of each second guide unit 73 forming the second guide 7. The bending guide 14 pivots each second guide unit 73 by contact with the curved surface 141 and the bottom wall 73b to bend the second guide 7 and return it to the left-right direction, so that the first stile 2 is left and right. Along with the slide, the second guide 7 can be smoothly stored and pulled out into the second storage portion 23. The predetermined curvature of the curved surface 141 can be appropriately set in consideration of such bending and returning of the second guide 7.

Further, in the screen device SD, a direction changing member 15 such as a pulley is provided at each of the upper and lower ends inside the first storage portion 22 of the first stile 2. Each direction changing member 15 is pivotally supported by blocks constituting the upper end portion and the lower end portion of the first storage portion 22. Each direction changing member 15 changes the direction of the tension member 8 up and down by applying the tension member 8 to a part of the outer peripheral surface thereof, and applies a predetermined tension to the tension member 8.

One end of the tension member 8 is fixed to the free end 71 of the second guide 7 by a screw or the like, the first accommodating portion 22 extends upward, and one direction changing member 15 located at the upper end portion of the first accommodating portion 22 is located. It is hung on the other to change its direction downward, is fixed to the free end 61 of the first guide 6, is hung on the other direction changing member 15 located at the lower end of the first storage portion 22, and changes its direction upward. The ends are fixed together with one end to the free end 71 of the second guide 7 to form a non-intersecting loop. With such a loop-shaped tension member 8, the storage length and the drawer length of the first guide 6 and the second guide 7 inside the first stile 2 become the same, and as a result, the first stile 2 is seconded. The slide can be surely parallel to the stile 3, and the parallel slide of the first stile 2 can be realized even if the user closes the first stile 2 at any part in the vertical direction. Further, the parallel slide of the first stile 2 is similarly realized at the time of opening operation by the elastic force of the coil spring 31a. The predetermined tension applied to the tension member 8 can be appropriately set in consideration of the slide of the first stile 2.

When fixing one end and the other end of the tension member 8 to the free end 71 of the second guide 7, the tension member 8 is allowed to enter the inside of the second storage portion 23 from the inside of the first storage portion 22. This approach is made possible by the protruding ends of both guide pieces 21 and 21 being separated in the Y-axis direction as shown in FIG. On the other hand, since the first stile 2 has a relatively long finding dimension, it may be difficult to fix the tension member 8 to the free end 71 of the second guide 7. In this case, a part of the guided member 12 forming the free end 71 is projected inside the first accommodating portion 22, and one end and the other end of the tension member 8 are fixed to the protruding portion to tension the tension member 8. It is possible to facilitate the fixing work of the second guide 7 of the member 8 to the free end 71. As shown in FIG. 7, an opening 24 communicating with the first storage portion 22 is formed on the left end surface of the first stile 2, and when wiring the tension member 8, the tension member 8 is passed through the opening 24 to the inside of the first stile 2. Can be inserted into. A cover (not shown) is detachably attached to the opening 24.

Although the present invention has been described above with respect to the above embodiment, the present invention is not limited to the above embodiment. For example, the screen device SD is provided with a motor in addition to the automatic storage type using the elastic force of the coil spring 31a as in the above embodiment, and automatically uses the torque when the motor rotates for the deployment and storage of the screen 1. It may be an opening / closing type or a manual opening / closing type in which both the expansion and storage of the screen 1 are performed manually. Further, as the screen 1, a screen in which a plurality of pleats that can be folded is formed can be adopted. Further, in the case of the manual opening / closing type screen device SD, the second stile 3 is not fixed to the opening, but is slidable in the left-right direction in the same manner as the first stile 2, so that the screen device SD is double-opened. can do. The Z-axis direction is not limited to the horizontal direction, and may be a direction orthogonal to the X-axis direction. For example, the screen device SD can also be installed in an opening that is inclined with respect to a vertical plane.
