JP 2000-1931 A

  However, since such a conventional screen is flat, it has very little change and has few functions other than partitioning the space. If the upper and lower frames are curved in the same shape, it is possible to form a cylindrically curved surface. However, if the opposite two sides have the same frame shape, the cross section of the tension material in the direction perpendicular to the opposite direction Since it takes the same shape as both frames, it takes only a simple curved surface as the screen surface. If an attempt is made to press a member such as a frame against the central portion of the tension member to form an odd-shaped standing surface, the continuity of the surface is cut off at the pressed portion, which is unpleasant. If you can configure various three-dimensional elevations without such problems, you can provide a highly valuable screen as an interior item that creates a more original space. Conceivable.

  The present invention, when realizing such an irregular elevation, is based on the assumption of a portable and self-supporting structure, especially considering the flexibility of arrangement and the extensibility of various elevations by combination. The object is to accurately configure a screen having an irregular elevation surface through a simple structure.

  In order to achieve this object, the present invention takes the following measures.

That is, the screen of the present invention includes a bottom frame that is curved or bent in plan view, and an upper frame that is opposed to the bottom frame via a support, and the upper frame has two bottom frames in plan view. A frame structure in which the center of gravity of the part extending from the support to the upper frame is positioned inside the range surrounded by the line connecting the bottom frame and the end of the bottom frame, while giving a shape that crosses the location The corresponding edge of the tension material is supported on at least the upper frame and the bottom frame of the frame structure, respectively, and a three-dimensional standing structure corresponding to the shape of both frames is provided between the edges of the tension material. It is characterized in that a plane is formed and is configured to stand on its own by grounding at three or more points .

With this configuration, the cross section of the tension material changes from one frame shape to the other frame shape from the upper frame toward the bottom frame, so that the middle portion has an odd shape that does not belong to any frame shape. A face will appear. At this time, the upper frame is given a shape that crosses two locations of the bottom frame in plan view, and the center of gravity of the portion extending from the support to the upper frame connects the bottom frame and the end of the bottom frame. since so as to be positioned inside the area surrounded by, if pursuing a variety of shapes while satisfying this condition, properly positioned is in free-standing relative to the bottom frame barycentric position as long as the shape of the support is not wild Is effectively secured. In particular, since the region where the tension material projects inward from the upper side frame toward the bottom side frame coexists with the region where the tension material projects outward, it is possible to create an unprecedented and complex elevation.

As a preferred embodiment of the support, there is a side frame that connects the upper side frame and the bottom frame in a closed loop shape, and the side frame also supports the corresponding edge portion of the tension material.

In that case, it is desirable that the shape of the side frame that further enhances the effect of the present invention is that at least a part thereof is bent or curved in side view.

Furthermore, as a preferable form, the upper side frame is formed in a substantially linear shape, and is smoothly curved and continuous with the side frame.

In order to further improve stability and height adjustment by ensuring the independence as described above, grounding adjusters are provided at both ends and the middle part of the bottom frame, and these grounding adjusters are the apexes of the triangle. It is effective to have a configuration in which three points are grounded because of the following relationship.

Further, instead of the configuration in which the grounding adjusters are provided at both ends and the middle part of the bottom frame, the grounding adjusters are respectively provided at the lower ends of the pair of side frames, and the side frames are crossed in a T shape. It is also effective to provide a grounding adjuster at the intermediate portion of the bottom frame to be connected and to ground these three points so that these grounding adjusters form a vertex of a triangle.

When a grounding adjuster is provided at the crossing part of the bottom frame and the side frame, in the vicinity of the crossing part, or at a part where any frame is extended from the crossing part, etc. In order to properly process the upholstery material, the side edge and the lower edge of the upholstery material are respectively provided with a side edge sewing portion and a lower edge sewing portion for inserting the side frame and the bottom frame, and the crossing portion is provided with the crossing portion. It is preferable to attach a cover member that is engaged with the side edge sewing portion and the lower edge sewing portion of the upholstery material and conceals the boundary portion.

Furthermore, it is more preferable that the end portion of the side edge sewn portion and the end portion of the lower edge sewn portion are separated from each other and positioned at the intersection of the bottom frame.

It is also preferable to form the bottom frame in a V shape in plan view that is bent at the middle part.

In order to effectively create a space using the above screen, a plurality of screens are configured by using a common shape for the side frame and different shapes of at least one of the top frame and the bottom frame. It is useful to develop a screen unit that can be used in combination. In addition to being able to partition the space by discretely arranging them individually, if the screens are closely adjacent to each other, the continuity of the elevation surface can be obtained on the side and the elevation surface can be effectively expanded. This is because it becomes possible.

According to the screen of the present invention, it is possible to effectively configure an odd-shaped standing surface having a simple structure and completely different from the conventional one while ensuring independence, thereby simply functioning as a partition for partitioning the living space. In addition, it has a high utility value as an item that creates a creative space by introducing a novel visual effect.

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

  FIG. 1 illustrates two types of the first screen 1 and the second screen 2 according to the present embodiment in a state in which a frame structure is exposed by partially crushing. Each of these screens 1 and 2 has a three-dimensional irregularly shaped vertical surface inside the frame by making the upper frames 11 and 21 and the bottom frames 12 and 22 different from each other and tensioning members 15 and 25 between them. The screens 1 and 2 are used as screens to create a living space rich in change and creativity.

  Specifically, as shown in FIGS. 1 to 3, the first screen 1 has a substantially straight upper frame 11 and a bottom frame 12 having a V-shaped plan view with an intermediate portion bent at an obtuse angle. It is mainly composed of a closed loop frame structure 1x composed of left and right side frames 13 whose upper ends are rectilinearly raised and warped back to the back side. The lower ends of the left and right side frames 13 and the bottom frame 12 A grounding adjuster 1a is provided at the lower end of the central portion. The upper side frame 11 and the side frame 13 are smoothly curved and continuous, and the side frame 13 and the bottom frame 12 cross in a T shape in a side view. In the present embodiment, a round pipe-shaped frame member (aggregate) is used for these frames 11, 12, and 13, and at least near the boundary between the upper frame 11 and the side frame 13, Although there exists a connection part, it does not ask | require in particular what kind of frame member is used including the cross-sectional shape. That is, the top frame 11, the bottom frame 12, and the side frame 13 referred to in the present invention pay attention to the assembled state, and the individual frame members are the top frame 11, the bottom frame 12, and the side frames. It is not always necessary to accurately correspond to the frame 13. For example, the specific structure is arbitrary, such as designing the frame member so that the connecting portion is located at a position avoiding the rounded portion of the side frame 13 and the upper frame 11.

  The frame structure 1x in the assembled state of the first screen 1 is such that the upper frame 11 constituting one of the two opposite sides is linear in plan view as described above, and the bottom frame 12 constituting the other is seen in plan view. Since they are V-shaped, they cross at two points p and q in a plan view, and do not have a common portion overlapping in parallel at any part. The frame structure 1x includes the center of gravity position O1 of only the upper frame 11 when the base frame 12 is regarded as a triangle including the virtual line L connecting the ends of the base frame 12, and the upper side from the side frame 13. The total center-of-gravity position O2 of the part extending over the frame 11 is set so as to be within the triangle, and the three grounding adjusters 1a described above are stably and independently grounded. The same applies to the state without the ground adjuster 1a. When the ground adjuster 1a is provided at a portion other than the end of the bottom frame 12, the center of gravity position only needs to be within the range of the triangle formed by the ground adjuster 1a.

  On the other hand, the upholstery material 15 shown in FIG. 1 is obtained by sewing a flexible translucent fabric such as a curtain material, and has an upper edge sewing portion 15a that is sewn in a bag shape at a portion extending from the upper edge to the side edge. A side edge sewing portion 15b is continuously formed, and a lower edge sewing portion 15c that can be closed in a bag shape by a fastener F (see FIG. 4D) is formed on the lower edge.

  And after inserting the upper edge sewing part 15a and the side edge sewing part 15b of the tension | tensile_strength material 15 into the frame member (aggregate) corresponding to the upper frame 11 as shown to Fig.4 (a), the same figure (b) As shown, the frame members (aggregate) corresponding to the side frame 13 are connected to both ends of the upper side frame 11, and the side edge sewing portion 15b is moved from the upper side frame 11 to the side frame 13 side. Before and after that, a frame member (aggregate) constituting the bottom frame 12 is connected between the proximal end portions of the side frame 13. Then, the lower edge sewing portion 15c of the upholstery material 15 that has been lowered from above is wound around the lower end side of the bottom frame 12 to close the fastener F shown in FIG. Thus, the bottom frame 12 is confined inside the lower edge sewing portion 15c.

  As a result, the upper edge, the lower edge and the side edge of the tension member 15 are respectively supported by the upper frame 11, the bottom frame 12 and the side frame 13 of the frame structure 1x connected in a closed loop shape. The tension member 15 is stretched in a state where tension is applied to the inside of the 1x closed loop, and an odd-shaped standing surface by the tension member 15 as shown in FIG. 1 is formed at the center.

  At that time, as shown in FIG. 4C, the end 15c1 of the lower edge sewing portion 15c inserted through the bottom frame 12 and the end 15b1 of the side edge sewing portion 15b inserted through the side frame 13 are divided. In this state, it is located at the intersection of the bottom frame 12 and the side frame 13 that forms a T-shape, and it is difficult to sufficiently reinforce the periphery of the boundary portion of the tension member 15. For this reason, when it is used as it is, there is a possibility that the tension member 15 is displaced when it is pulled toward the center, or the tension member 15 is torn from the boundary portion.

  Therefore, in the present embodiment, a cover member 16 is attached to the intersection as shown in FIG.

  This cover member 16 is inserted from the lower side of the side frame 13 in a state where the installation adjuster 1a is not connected, and is positioned at the crossing portion having a T-shape. As shown in FIGS. A cylindrical fitting portion 16a fitted to the side frame 13 below the crossing portion, a pair of opposing pieces 16d positioned so as to cover the corners of the side frame 13 and the bottom frame 12, and a crossing portion A partially cylindrical engaging portion 16b that engages with the side frame 13 at a position above the side frame 13 and a partially cylindrical engagement portion that engages with the bottom frame 12 at a position inward of the crossing portion. The engaging portion 16c is integrally molded with resin. At this time, protrusions 16e are provided on the inner circumferences of the engaging portions 16c and 16d, and the protrusions 16e are engaged with the side edge sewing portion 15b and the lower edge sewing portion 15c of the tension member 15 at the attachment position. Accordingly, the corners of the tension member 15 including the end portions 15b1 and 15c1 of the sewing portions 15b and 15c are concealed while preventing the displacement of the tension member 15.

  On the other hand, the basic structure of the second screen 2 shown in FIG. 1 is the same as that of the first screen 1 except that the top frame 21 and the bottom frame 22 are different from the top frame 11 and the bottom frame 12 of the first screen 1. It is.

That is, as shown in FIGS. 1, 7 and 8, the second screen 1 has an upper frame 21 having a partial arc shape in plan view and a bottom side having a V shape in plan view with a middle portion bent substantially at a right angle. The frame 22 is mainly composed of a frame structure 2x having a left and right side frame 23 which is formed of a left and right side frame 23 which rises in a straight line and warps at least the upper end side to the back side. A grounding adjuster 2a is provided at the lower end of the central portion of the. Similar to the first screen 1, there is a connection portion of the frame member at least near the boundary between the upper frame 21 and the side frame 23, but the individual frame members are the upper frame 21, the bottom frame 22, and the side frame 23. As described above, it is not always necessary to accurately correspond to the above.

  The frame structure 2x in the assembled state of the second screen 2 has a shape in which the upper side frame 21 constituting one of the two opposing sides is curved in an arc shape in plan view, and the bottom frame 12 constituting the other is seen in plan view V It has a letter shape, and the two do not have a common portion that overlaps each other in parallel other than crossing at two points r and s. This frame structure 2x also has a center-of-gravity position O3 of only the upper frame 21 when the base frame 22 is regarded as a triangle including an imaginary line L connecting the ends of the base frame 22, and the upper side from the side frame 23. The total center-of-gravity position O4 of the portion extending over the frame 21 is in a relationship that can be accommodated inside the triangle, and is stably and independently grounded by the three ground adjusters 1a described above.

As in the first screen 1, the upholstery material 25 shown in FIG. 1 includes an upper edge sewing portion 25a, a side edge sewing portion 25b, and a lower edge sewing portion 25c.

In the second screen 2, the side frame 23 has the same shape as the side frame 13 of the first screen 1, and the upper frame 21 and the bottom frame 22 are the upper frame 11 and the bottom frame 12 of the first screen 1. It is different.

The effects of the screens 1 and 2 of the present embodiment configured as described above will be described below with the first screen 1 as a main component.

That is, the first screen 1 includes a bottom frame 12 that is bent in a V shape in plan view, and an upper frame 11 that is opposed to the bottom frame 12 via a side frame 13 that is a support. A frame structure 1x is formed by giving the frame 11 a shape traversing two locations p and q (parts indicated by symbols r and s in the second screen 2) of the bottom frame 12 in plan view. The upper and lower edges of the upholstery material 15 are supported by both the frames 11 and 12 of the body 1x, respectively, and a three-dimensional upright surface corresponding to the shape of the frames 11 and 12 is provided between the both edges of the upholstery material 15. Formed.

Through this configuration, the shape of the upper frame 11 is different from the shape of the bottom frame 12, so that the cross section of the upholstery material 15 changes from a linear shape to a V shape from the upper frame 11 to the bottom frame 12. (Transition from the bow shape to the V shape in the second screen 2), therefore, an irregular elevation that does not belong to any frame shape appears in the intermediate portion. At this time, the upper frame 11 crosses two places p and q (r and s in the second screen 2) of the bottom frame 12 in plan view, and the center of gravity position O1 (O3 in the second screen) of the upper frame. ) And the center of gravity position O2 (O4 in the second screen) of the portion from the side frame 13 to the upper frame 11 is also within the triangle of the bottom frame 13, so that the independence is effectively secured. In particular, when there is a difference in the frame shape as described above, a region in which the upholstery material 15 projects inward from the upper frame 11 toward the bottom frame 12 and a region in which the tension material 15 projects outwardly form a complex elevation surface. Therefore, it becomes possible to create a more original and unusual elevation.

In this embodiment, a side frame 13 that connects the upper frame 11 and the bottom frame 12 in a closed loop shape is used as a support, and the corresponding edge of the upholstery material 15 is also supported on the side frame 13. In addition, since the frame member is not pressed against the central surface of the screen, the central surface of the screen can be configured only by the tension member 15. Moreover, not only can tension be applied to the tension member 15 between the upper frame 11 and the bottom frame 12, but also the lateral tension can be applied to the tension member 15 from the side frame 13, so that the entire tension member is tensioned. Thus, it is possible to more smoothly and clearly reveal the elevation shape from the upper edge to the lower edge.

Furthermore, if the side frame 13 is a straight line, both end positions of the upper side frame and the bottom frame must substantially coincide with the end portions of the side frame in plan view. In this embodiment, the upper side of the side frame 13 is curved toward the rear in side view, and the upper side frame 11 is changed to the bottom side frame 12. On the other hand, since it is displaced in the horizontal direction, it is possible to substantially realize the relative relationship of intersecting at two points in plan view as described above. As described above, the side frame 13 is bent or curved, so that the degree of freedom related to the horizontal position and shape of both the frames 11 and 12 is remarkably increased. And since the corresponding edge part of the tension | tensile_strength material 15 is supported by such a side frame 13, it can also contribute to the unusual-shaped standing surface structure of the tension | tensile_strength material 15. FIG.

Also, because of the above-mentioned independence, the ground frame adjusters 1a are provided at both ends and the middle portion of the bottom frame 12, and the ground adjusters 1a are configured to be grounded at three points so as to form a vertex of a triangle. In addition, the height can be adjusted while further ensuring stability, which can contribute to layout design effectively.

Furthermore, as compared with the frame structure 1x in which the ground adjuster 1a is provided at the intersection of the bottom frame 11 and the side frame 13 as described above, the tension member 15 side has the side frame 13 on the side edge and the lower edge. Further, a side edge sewing portion 15b and a lower edge sewing portion 15c for inserting the bottom frame 12 are provided. In this embodiment, the side edge sewing portion 15b of the tension member 15 is provided at the crossing portion of the frame structure 1x. In addition, a cover member 16 that engages with the lower edge sewing portion 15c and hides the boundary portion is attached. For this reason, even if the end 15b1 of the side edge sewn portion 15b and the end 15c of the lower edge sewn portion 15c do not interfere with the crossing portions of the frames 13, 12, the sewn end is appropriately It can be blindfolded to ensure a good appearance, and even when tension is applied to the upholstery material 15, it can appropriately prevent problems that the upholstery material 15 is misaligned or that the upholstery material 15 is torn from the boundary portion. can do.

  The same applies to the second screen 2.

The first screen 1 and the second screen 2 configured in this embodiment use a common shape for the side frames 13 and 23, and the shapes of the upper side frames 11 and 21 and the bottom side frames 21 and 22 are different. Therefore, when these screens are used in combination, it is possible to arrange the screens so as to partition the spaces individually. If the screens 1 and 2 are closely adjacent to each other, the side frames 13, 23 matches, the continuity of the vertical surface is obtained, and the vertical surface can be effectively expanded in the width direction.

Furthermore, the cover member 15 has a tension member 15 stretched inside the frames 13 and 12 intersecting in a T shape as shown in the illustrated example, and the tension member 15 is attached to each frame 13 and 12 at the corresponding edge portion. As long as the screen has the sewing parts 15b and 15c for insertion, it can be applied to other than the illustrated example, and the boundary part can be concealed by engaging with both sewing parts of the tension member 15 in the attached state. Will be played.

The specific configuration of each part is not limited to the above-described embodiment, and the shape of the upper frame and the bottom frame can be variously modified in addition to the illustrated examples.

For example, the bottom frame may have a curved shape in addition to the V shape, or the arrangement of the top frame 111 itself as well as the center of gravity of the top frame 111 as shown in FIG. It is also effective to make the shape fit within the range of a triangle surrounded by a virtual line L that connects the ends of the bottom frame 112.

Even if it does in this way, it can ensure the independence of the frame structure, and the three-dimensional surface has the desired effect of the present invention even if it is not extremely deformed as described above, and the position of the center of gravity is stable, so it is portable. It is useful as a screen with good usability.

In the above embodiment, the upper frame is configured to cross the bottom frame at two locations in plan view. However, if the upper frame is configured to cross the bottom frame at least at one location in plan view, the operation according to the above embodiment is performed. An effect is produced.

Furthermore, if the center of gravity of the part extending from the support body to the upper frame is positioned within the range surrounded by the line connecting the bottom frame and the end of the bottom frame, the bottom frame is the upper frame in plan view. Also, a frame structure that passes through the inside of a range surrounded by a line connecting the end portions of the upper frame, that is, a frame structure having a larger upper frame than the bottom frame can be effectively configured.

Other configurations can be variously modified without departing from the spirit of the present invention.
