Description

Technical Field

[0001] The present invention relates to a fabric sheet mounting frame for mounting a fabric sheet (hereinafter referred to as a "fabric sheet") and a display panel in which the fabric sheet is mounted on the fabric sheet mounting frame.

Background Art

[0002] In commercial facilities, stores, show windows, restaurants, hotels, etc., display panels or panel signs (hereinafter referred to as "display panels") called tension fabrics or fabric frames may be used as guidance signs or interior decorations. This tension fabric (fabric frame) is obtained by applying tension to a frame with a fabric (a fabric such as synthetic fiber) medium printed with graphics or the like. Such tension fabrics are available in various sizes depending on the installation location and the content to be displayed, and many large-sized ones are also used. Therefore, when installing a tension fabric, it is desirable to assemble the divided frames at the installation location and attach the fabric medium.

[0003] By the way, various proposals have been made from the viewpoint of ease of assembly and the like for exhibits and the like that divide a frame or a frame, assemble the divided parts, and attach a sheet-like object. For example, Patent Document 1 (Utility Model Registration No. 3121624) discloses a frame comprising: a frame body 2 formed as a substantially rectangular frame and having an insertion groove 201 formed along its entire inner circumference; a transparent body 3 that is deformable into a cylindrical shape or foldable and supported within the frame body 2 with its peripheral edge inserted into the insertion groove 201; and a back plate 4 that is deformable into a cylindrical shape or foldable and supported within the frame body 2 with its peripheral edge overlapping the back side of the transparent body 3 and its peripheral edge inserted into the insertion groove 201, wherein the frame body 2 is separable into a plurality of frame body parts 5a, 5b, 6a, 6b near the central portion in the vertical or horizontal direction, and the plurality of frame body parts 5a, 5b, 6a, 6b are separably connected by connecting means 7. However, in the frame of Patent Document 1, an insertion groove 201 is formed around the entire inner circumference of the frame body 2, and the transparent body 3 and backing plate 4 are inserted into the insertion groove 201. As a result, not only is it impossible to attach a sheet-like material to the frame by applying tension from the front, but the front portion of the frame body 2 is largely exposed to the outer circumference of the transparent body 3, resulting in an extremely poor appearance when used as an interior display panel or panel sign. Furthermore, in the frame described in Patent Document 1, the frame body 2 is simply separated into multiple frame body sections 5a, 5b, 6a, and 6b, and the size of the frame body 2 itself is constant, so it is not possible to attach sheet-like materials of various sizes.

[0004] In this regard, Patent Document 2 (Utility Model Registration No. 3051366) describes a picture frame 1 for displaying an exhibit 5, which is assembled in a rectangular frame shape with four rod-shaped frame bones 2 and four connecting members 3 that connect these frame bones 2, and a front panel 4, an exhibit 5, and a back panel 6 are fitted in order into the inner circumference of the frame shape to hold them in place, and the frame bones 2 have a stepped portion 2a that protrudes inward on their front side, and this stepped portion 2a is designed to receive the outer edge 4a of the front panel 4, and the connecting members 3 have L-shaped sides 3a, 3a that connect the frame bones 2 A picture frame 1 is disclosed which has an insertion hole 7 into which the end of the connector 3 is inserted, and L-shaped engaging recesses 10 are formed on both inner sides of the corner 3b of the connector 3 in the front-back direction, and an L-shaped engaging projection 11 that is perpendicular to an engaging member 8 which is roughly Y-shaped in plan view engages with the engaging recess 10, and two pressing parts 12, 12 extend from the base 8a of the engaging member 8 in a V-shape that opens at approximately 90 degrees, and the pressing parts 12a of the pressing parts 12, 12 press the back plate 6 to the front side so that the front plate 4, the exhibit 5 and the back plate 6 are held in place. In this Patent Document 2, the frame frame 2 is made of wood so that it can be cut to an appropriate length, and the size of the frame can be adjusted. However, in the picture frame 1 of Patent Document 2, a stepped portion 2a that protrudes inward is formed on the front side of the frame frame 2, and the front panel 4, the exhibit 5, and the back panel 6 are fitted in order into the frame-shaped inner circumference, and the pressing portion 12a of the pressing portion 12 of the engaging member 8, which is engaged with the engaging recess 10 of the corner portion 3b of the connecting member 3, is merely pressing the back panel 6 to the front side. Therefore, similar to Patent Document 1, not only is it not possible to attach the exhibit 5 (sheet-like object) with tension from the front side of the picture frame 1, but the front part (front portion) of the frame frame 2 is largely exposed on the outer circumference of the exhibit 5, resulting in an extremely poor appearance when used as an interior display panel or panel sign.

[0005] Furthermore, Patent Document 3 (Utility Model Registration No. 3114456) describes a picture frame in which the surrounding frame A consists of a plurality of corner frame pieces a, a plurality of straight frame pieces b, and a plurality of locking keys c, c', the corner frame pieces a and the straight frame pieces b are connected at their ends so as to be able to move toward and toward each other, and the straight frame pieces b are also connected at their ends so as to be able to move toward and toward each other, and the locking keys c, c' lock each of the above-mentioned connected parts, wherein the corner frame piece a has one extension piece 1 and the other extension piece 1' arranged in an L shape, and a missing cylindrical recess 2 is formed at the outer end of the one extension piece 1, and the other A picture frame is disclosed in which a cylindrical projection 3 is formed on the outer end of the side extension piece 1', and an L-shaped notched step a' is formed between the back side and the inner circumferential surface of the one side extension piece 1 and the other side extension piece 1', and a keyway 4 is cut into the inner surface of the L-shaped notched step a', and the straight part frame piece b has a notched cylindrical recess 5 at one end and a cylindrical projection 6 at the other end, and an L-shaped notched step b' is formed between its back side and the inner circumferential surface, and a keyway 7 is cut into the inner surface of the L-shaped notched step b', and the locking keys c and c' engage with the keyways 4 and 7 to lock each of the connecting parts. In this Patent Document 3, by increasing or decreasing the number of frame pieces (frame piece b for the straight section), picture frames of various sizes with different overall dimensions can be assembled. However, in the picture frame of Patent Document 3, the locking keys c and c' are engaged in the key grooves 4 and 7 at a position that spans each of the connecting parts, thereby fixing the outer peripheral edge of the thin-layer display, such as a jigsaw puzzle board C placed in the L-shaped notched steps a' and b' to the L-shaped notched steps a' and b'. As a result, similar to Patent Documents 1 and 2, it is not possible to attach the thin-layer display with tension from the front side of the picture frame, and the front part (front portion) of the surrounding frame A is largely exposed to the outer circumference of the thin-layer display, resulting in an extremely poor appearance when used as an interior display panel or panel sign. Furthermore, in Patent Document 3, the length of the surrounding frame A is changed by increasing or decreasing the number of frame pieces (frame pieces b for the straight section), so the size can only be changed in units of the length of the frame pieces b for the straight section, and it is not possible to adjust minute sizes smaller than the length of the frame pieces b for the straight section.

[0006] Furthermore, Patent Document 4 (Japanese Unexamined Patent Publication No. 2019-118537) discloses an assembly-type oil painting frame 10, which has a frame structure for displaying a canvas, comprising a rectangular assembly frame 20 and frame rod members 30, wherein the assembly frame 20 consists of angle structure corner members 21 arranged at the four corners of the canvas and peripheral members 22 that connect the corner members 21 to each other, and the frame rod member 30 consists of a corner frame rod 31 formed on the corner members 21 and a peripheral frame rod 32 formed on the peripheral member 22, and after the peripheral member 22 is fitted into the corner member 21, the corner frame rod 31 of the corner member 21 and the peripheral frame rod 32 of the peripheral member 22 are bonded to each other. In the assembled oil painting frame 10 of this Patent Document 4, the peripheral member 22 has cutting lines formed at predetermined intervals, and the length of the peripheral member 22 can be shortened by cutting along the cutting lines. However, the assembly-type oil painting frame 10 of Patent Document 4 is a picture frame with a frame structure for inserting and displaying a canvas, and like Patent Documents 1 to 3, it is not possible to attach a sheet-like material to the rectangular assembly frame 20 by applying tension from the front side. Moreover, the front portion of the assembly frame 20 is largely exposed to the outer perimeter of the canvas, resulting in an extremely poor appearance when used as an interior display panel or panel sign.

[0040] Next, if the fabric sheet mounting frame 1 is not fixed to the wall on the second floor, but is leaned against the wall on the second floor or another wall, installed on a mounting stand, or suspended from the ceiling, etc., then small screws and nuts that fit onto them are used instead of wood screws 51a~51d, 52a~52d, 53a~53d, 54a~54d, 61a, 61b, 62a, 62b, 63a, 63b, 64a, 64b, and wood screws 71a~71d, 72a~72d, 73a~73d, 74a~74d are not used. Specifically, small screws are inserted through the insertion holes 41a and 41b of the upper left L-shaped plate 41, which overlap the insertion holes 11Hf and 11Vf of the upper left corner 11, and nuts are screwed onto them, connecting the upper left corner horizontal frame 11H and the upper left corner vertical frame 11V to form the upper left corner 11. Similarly, small screws are inserted through the insertion holes 42a and 42b of the lower left L-shaped plate 42, which overlap the insertion holes 12Hf and 12Vf of the lower left corner 12, and nuts are screwed onto them, connecting the lower left corner horizontal frame 12H and the lower left corner vertical frame 12V to form the lower left corner 12. Similarly, small screws are inserted through the insertion holes 43a and 43b of the lower right L-shaped plate 43, which overlap the insertion holes 13Hf and 13Vf of the lower right corner 13, and nuts are screwed onto them, connecting the lower right corner horizontal frame 13H and the lower right corner vertical frame 13V to form the lower right corner 13. Similarly, small screws are inserted through the insertion holes 44a and 44b of the upper right L-shaped plate 44, which overlap the insertion holes 14Hf and 14Vf of the upper right corner portion 14, and nuts are screwed onto them, connecting the upper right corner horizontal frame 14H and the upper right corner vertical frame 14V to form the upper right corner portion 14.

[0041] Furthermore, small screws are inserted through the insertion holes 31La and 31Lb of the left upper sliding plate 31L, which overlap with the insertion hole 21f of the upper left corner horizontal frame 11H and the insertion hole 21f of the upper straight section frame 21, and nuts are screwed onto them. Small screws are also inserted through the insertion holes 31Ra and 31Rb of the right upper sliding plate 31R, which overlap with the insertion hole 21i of the upper straight section frame 21 and the insertion hole 14Hh of the upper right corner horizontal frame 14H, and nuts are screwed onto them. In this way, the upper left corner horizontal frame 11H and the upper right corner horizontal frame 14H are connected to both ends of the upper straight section frame 21. Similarly, small screws are inserted through the insertion holes 32Ua and 32Ub of the upper left sliding plate 32U, which overlap with the insertion hole 22f of the upper left corner vertical frame 11V and the insertion hole 22f of the left straight section frame 22, and nuts are screwed onto them. Small screws are also inserted through the insertion holes 32La and 32Lb of the lower left sliding plate 32L, which overlap with the insertion hole 22i of the left straight section frame 22 and the insertion hole 12Vh of the lower left corner vertical frame 12V, and nuts are screwed onto them. In this way, the upper left corner vertical frame 11V and the lower left corner vertical frame 12V are connected to both ends of the left straight section frame 22. Similarly, small screws are inserted through the insertion holes 32La and 32Lb of the lower left sliding plate 32L, which overlap with the insertion hole 23f of the lower straight section frame 23, and nuts are screwed onto them. Small screws are also inserted through the insertion holes 33Ra and 33Rb of the right lower sliding plate 33R, which overlap with the insertion hole 23i of the lower straight section frame 23, and the insertion hole 13Hh of the lower right corner horizontal frame 13H, and nuts are screwed onto them. In this way, the lower left corner horizontal frame 12H and the lower right corner horizontal frame 13H are connected to both ends of the lower straight section frame 23. Similarly, small screws are inserted through the insertion holes 34Ua and 34Ub of the upper right sliding plate 34U, which overlap with the insertion hole 24f of the right straight section frame 24, and nuts are screwed onto them. Small screws are also inserted through the insertion holes 34La and 34Lb of the lower right sliding plate 34L, which overlap with the insertion hole 24i of the right straight section frame 24, and the insertion hole 13Vh of the right lower corner vertical frame 13V, and nuts are screwed onto them. In this way, the upper right corner vertical frame 14V and the right lower corner vertical frame 13V are connected to both ends of the right straight section frame 22. As a result, each corner horizontal frame and each corner vertical frame are connected with screws and nuts to form each corner frame, and each corner frame and each straight section frame are connected with screws and nuts to form the rectangular frame body 1A.

[0042] [Fabric sheets, display panels] Figure 11 is a perspective view of the fabric sheet attached to the fabric sheet mounting frame 1, viewed from the back; Figure 12 is a front view of the display panel with the fabric sheet shown in Figure 11 attached to the fabric sheet mounting frame 1; Figure 13(a) is a cross-sectional view of AA in Figure 12; and Figure 13(b) is a cross-sectional view of BB in Figure 12. In the diagram, 3 is a cloth sheet, 4 is a sheet body, 4F is the surface of the sheet body, 4R is the back surface of the sheet body, 5a, 5b, 5c, and 5d are elastic pieces, and 80 is a display panel. As shown in Figure 11, the cloth sheet 3 comprises a sheet body 4 and elastic pieces 5a, 5b, 5c, and 5d. Sheet body 4 is a sheet of fabric with a rectangular shape in which the four corners have been cut off, and a graphic (not shown) is printed on the surface 4F of the sheet body. The elastic pieces 5a, 5b, 5c, and 5d are strip-shaped bodies made of an elastic material such as silicone rubber, and are sewn to the sheet body 4 with thread along each edge of the back surface 4R of the sheet body. Specifically, elastic piece 5a is attached to the back surface 4R of the sheet body by sewing it with thread along the upper edge of the back surface 4R of the sheet body, elastic piece 5b is attached along the left edge of the back surface 4R of the sheet body, elastic piece 5c is attached along the lower edge of the back surface 4R of the sheet body, and elastic piece 5d is attached along the right edge of the back surface 4R of the sheet body. The longitudinal length of each elastic piece 5a, 5b, 5c, and 5d is the same as the length of each edge (upper edge, left edge, lower edge, and right edge) of the sheet body 4, and the transverse length of each elastic piece 5a, 5b, 5c, and 5d is slightly less than the depth (length in the front-to-back direction) of the grooves 21m of each corner frame and each straight section frame of the fabric sheet mounting frame 1. Furthermore, the thickness of the portion of the cloth sheet 3 to which the elastic pieces 5a, 5b, 5c, and 5d are attached (hereinafter referred to as the "elastic piece attachment portion") is slightly greater than the width of the outer edge groove 1Am1 of the rectangular frame body of the cloth sheet attachment frame 1 (the vertical length of the outer edge groove 1Am1 of the rectangular frame body).

[0043] The fabric sheet 3 is attached to the outer edge grooves 1Am1 to 1Am4 of the rectangular frame body of the fabric sheet mounting frame 1, which is fixed to the wall surface 2F, thereby forming the display panel 80. Specifically, the mounting portion of elastic piece 5a is fitted into the outer edge groove 1Am1 of the rectangular frame, the mounting portion of elastic piece 5b is fitted into the outer edge groove 1Am2 of the rectangular frame, the mounting portion of elastic piece 5c is fitted into the outer edge groove 1Am3 of the rectangular frame, and the mounting portion of elastic piece 5d is fitted into the outer edge groove 1Am4 of the rectangular frame (see Figures 13(a) and (b)). At this time, the length of each elastic piece attachment portion (each edge of the sheet body 4) is the same as the length of each rectangular frame outer edge groove 1Am1 to 1Am4 (each edge of the rectangular frame body 1A), and the thickness of the elastic piece attachment portion is slightly larger than the width of the rectangular frame outer edge groove 1Am1 to 1Am4. Therefore, when tension is applied to the sheet body 4 and the elastic piece attachment portions are fitted into the rectangular frame outer edge grooves 1Am1 to 1Am4, the elastic piece attachment portions are fitted into the rectangular frame outer edge grooves 1Am1 to 1Am4 without any gaps in the longitudinal direction of the rectangular frame outer edge grooves 1Am1 to 1Am4, and the elastic pieces 5a, 5b, 5c, and 5d press against the inner surfaces of each rectangular frame outer edge groove 1Am1 to 1Am4. As a result, in the display panel 80, the front portion of the fabric sheet mounting frame 1 is covered by the fabric sheet 3, except for the front portions of the first ribs of each corner frame (first rib 11Hb, etc.) and the first ribs of each straight section frame (first rib 21b, etc.), so it is hardly exposed, and the appearance of the fabric sheet 3 is not spoiled by the fabric sheet mounting frame 1. [Industrial applicability]

[0044] The fabric sheet mounting frame and display panel of the present invention allow the fabric sheet to be attached to the frame under tension from the front side, and the front portion of the frame is hardly exposed around the outer edge of the fabric sheet, so the appearance of the fabric sheet is not spoiled by the frame, the size of the frame can be finely adjusted, and it can be used for guide signs and interiors such as tension fabrics.
