DETAILED DESCRIPTION OF THE INVENTION

[0001]

The display panel and graphics Tsu Kupaneru various control facilities and monitoring facilities BACKGROUND OF THE, referred to as a mosaic panel, in each square path of a grid was cross-cut in a lattice shape by partition walls of the vertical and horizontal illumination display device There is known a device which comprises a board surface mounted with a blind tile, an instrument, or the like (hereinafter simply referred to as a tile).

[0002]

2. Description of the Related Art Such a mosaic panel, especially a large-sized mosaic panel, is required to have a monitoring position in accordance with an installation place or installation condition, or in order to facilitate design reasons or monitoring. A display surface is formed on a center circle. Further, even for a relatively small display device, it is required to form a display surface on a circumference centered on a monitoring position, that is, to curve the display surface in order to improve visibility. The present invention relates to a curved mosaic panel that curves the display surface.

In a conventional curved mosaic panel, as shown in FIG. 14, a plurality of planar mosaic panels A, A (divided into five in the drawing) are arranged on a circumference having a radius R centered on a monitoring position O. Thus, one curved mosaic panel is constituted as a whole by the display surfaces of the plurality of planar mosaic panels that are abutted. In the drawing, B is a monitoring desk, and C is a monitoring desk.

[0004] One planar mosaic panel A is composed of a plurality of display portions A 'and A' as shown in FIG.
Some of them are arranged on the circumference of the radius of curvature R so as to give the impression of a more natural curved surface as a whole. In the planar mosaic panel shown in FIG. 15, grids F, F corresponding to display portions A ', A' are fixed to a rear angle frame D by support rods E, and tiles G are attached to the grids F, F, respectively. Is configured.

[0005]

The conventional curved mosaic panel shown in FIG. 14 has a display surface formed by a combination of the plane mosaic panel A, and is therefore arranged on the circumference of the radius R. However, unlike the curved surface, the impression of the polyhedral shape was strong and uncomfortable, and the display surface was not always easy to see.

Further, in the curved mosaic panel shown in FIG. 15, since a single plane mosaic panel A is composed of a plurality of display portions A 'and A', the impression of a polyhedral shape is improved to some extent, but the display of a curved surface is still possible. It is not a plane. And
Adjacent display portions A ', A' must be fixed in a state where the grids F, F of the display portions A ', A' are separated by a certain distance so that the surface of the mounted tile is in contact therewith. Therefore, there are drawbacks in that it takes time to manufacture and install the curved mosaic panel, and the adjacent grids F, F cannot be connected to each other, so that the strength is weak and there is a possibility that the display surface may be displaced.

[0007] The present invention has been made in consideration of the drawbacks of the prior art, on the circumference around the monitor position O as shown in FIG. 2, it has excellent visibility by forming a display surface in a continuous curved surface And
When mounting the positive square tile grid, without causing excessive gaps around the tile, and so that is not disturbing the mounting. In addition, the grid can be configured as a large grid by connecting a plurality of grid blocks, compared to a conventional curved mosaic panel ,
The purpose is to provide a mosaic panel excellent in strength. Another object of the present invention is to provide a method capable of efficiently manufacturing the grid block.

[0008]

As shown in FIG. 1 [SUMMARY OF], the longitudinal partition walls 2 and the lateral partition walls 3 to each square paths 4,4 of grid 1 which is formed in a lattice shape, the positive square Tile 5
Is mounted on the mosaic panel to form a board surface, the grid 1 is vertically or horizontally curved so that the front surface is a concave curved surface having a preferable radius of curvature as a display surface.

[0009] pitch <br/> Chi partition walls of the grid 1 to the curved, the pitch P ₂ of the non-curved direction of the partition wall, slightly larger than the outside dimension L of one side of the tile 5 to be mounted, bending direction partitioning the pitch P ₁ of the wall, of the non-curved direction of the partition wall
Larger form than the pitch _{P 2.}

The grid 1 for mounting the tiles 5 to form a curved mosaic panel is a small grid block 13 curved in a constant vertical or horizontal plane direction.
Can be connected to form a large grid. The small grid block 13 is used for the vertical partition wall 2.
At all intersections of the partition wall 3 with the horizontal direction, a cylindrical boss 12 projecting from the partition wall and having a tip serving as a bearing surface of the tile is formed, and the peripheral vertical partition wall 2 ′ and the lateral direction are formed. Is formed by cutting the inner vertical partition wall 2 and the horizontal partition wall 3 at the center of the thickness.
In order to efficiently manufacture the grid block 13, first, the grid block 13 is formed into a planar shape that is easy to manufacture. Subsequently, both ends in the bending direction of the grid block molded into a planar shape are supported by the fixed support 20. The grid block supported by the fixed support 20 is separated by a tooth block die 21 having a pressing piece 22 protruding along a curved surface to be machined at every pitch of the partition wall in the bending direction.
The partition wall portions of the curving is pressed against the surface direction.

[0011]

[Action] In the longitudinal partition wall 2 and the lateral partition walls 3 are formed in a lattice shape and attaching the positive square tiles 5 to the grid 1 which has been bent in the plane direction, it is attached to each square path tiles will be oriented in the direction of the center of curvature of each curved surface. Therefore, the tips (surfaces) of the tiles adjacent to each other in the curving direction approach by a certain dimension determined by the height H of the tile 5 and the radius of curvature R of the grid.

[0012] The pitch is smaller than the pitch of the partition wall in the non-curved direction.
When the tiles 5 having a very small external dimension L are mounted on the grid 1, they are arranged with a small gap in the non-curved direction.
On the other hand the curved direction, the pitch P ₁ of the partition wall of the bending direction,
Since that is formed larger than the pitch P ₂ of the non-curved direction of the partition wall, the surface of the adjacent tiles are mounted without colliding despite approaches.

The grid 1 of the curved mosaic panel is formed by connecting a curved grid block 13 to a curved surface having a constant radius of curvature to form a large grid which is a curved surface having a constant radius of curvature as a whole. In order to manufacture the grid block 13, a grid block molded into a plane that is easy to manufacture is divided into partition walls in the curved direction of the grid.
Tooth die 2 a pressing piece 22 for each pitch P ₁ of the projects
When pressed at 1, the pressing piece 22 directly abuts the partition wall in the bending direction avoiding the intersection of the vertical and horizontal partition walls, and the bending process can be performed without being affected by the structure of the intersection portion.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 2 is a plan view showing an example of use of the curved mosaic panel. In this example of use, the curved mosaic panel 7 having a curved shape on a circumference centered on the monitoring position O of the monitoring desk 6 and separated from the monitoring desk 6 by a certain distance R from the center. Place and monitor desk 6
A monitor desk 8 is disposed between the curved mosaic panel 7. That is, the display surface of the curved mosaic panel 7 is formed as a curved surface having a radius of curvature R.

[0015] The size and radius of curvature of the curved mosaic panel are determined depending on the application and the installation location. Generally, large monitoring panels in various monitoring facilities include:
Those having a radius of curvature R of about 10 to 15 meters are required. In such a large-sized curved mosaic panel, a partially curved mosaic panel 7 'as shown in FIG. 3 is arranged in combination at an installation location to constitute one large curved mosaic panel.

The partially curved mosaic panel 7 'shown in FIG.
A grid holding frame 10 is provided on an arc-shaped main body 9 which forms a part of a large-sized curved mosaic panel 7, the grid 1 is fixed to the grid holding frame 10 by supporting rods 11, 11, and a tile is provided on a grid of the grid 1. 5 is attached to form a board surface. When a plurality of the partially curved mosaic panels 7 'are arranged on a circumference having a radius R, their display surfaces are continuously viewed. When the grids of the plurality of partially curved mosaic panels 7 'arranged on the circumference of the radius R are connected to the grids of the adjacent partially curved mosaic panels 7', the entire grid of the curved mosaic panels is connected. The display surface is continuous, there is no risk of displacement, and the strength of the grid increases.

The grid 1 shown in FIG. 1 can be formed of a metal material such as an aluminum alloy or a synthetic resin material. The grid 1 is formed in a grid pattern by a vertical partition wall 2 and a horizontal partition wall 3.
Pitch P ₁ in the transverse direction of the partition wall is a curved direction is in a slightly larger than the pitch P ₂ in the longitudinal direction of the partition wall is non-curved direction. Further, the longitudinal compartment walls 2 and intersections of the partition walls 3 in the lateral direction, is provided a cylindrical boss 12. Boss 12 of cylindrical shape, and for securing the grid to the holding frame 10 by inserting the support rod,
For configuring a large grid 1 by I set seen if a small grid blocks 13, are used for connection to what grid block 13. Further, since the front and back ends of the boss 12 project beyond the front and back end surfaces of the partition wall, the boss 12 functions as a support surface of the tile 5 mounted on the grid 1 .

The partition wall 3 in the horizontal direction of the grid 1 is curved in the surface direction where the front surface is concave so that the display surface is curved to have a desired curvature radius R, for example, a curvature radius of 10 to 15 meters. I have. The tiles 5 to be attached to the grids 4 of the grid 1 are square blocks each having an outer dimension L whose one side is equal to the pitch dimension of the partition wall in the non-curved direction of the grid and a constant height H. , Including the leg pieces 5a, 5a for locking to the partition wall of the grid 1, are integrally molded of a synthetic resin material. The grid 1 is provided with an illuminated display device and instruments in addition to the blind tiles to constitute a board surface. Even if these instruments and the like have different internal structures, the external dimensions and the dimensions of the mounting means with respect to the grid are different. , The same as the above tiles.

When the tiles 5 are mounted on the concavely curved grid 1, each of the mounted tiles faces the center of the curve. Therefore, the tile surface adjacent to the bending direction as shown in FIG. 4, the radius of curvature R, toward each other by a predetermined dimension determined by the pitch of the height H and the curved direction of the partition wall of the tile.

The tiles to be mounted on a known flat mosaic panel are determined by measuring the outer dimensions of the tiles by the pitch of the partition walls of the grid.
DOO, etc. properly, so that is no gap arranged in the panel board. Strictly speaking, the pitch is slightly smaller than the pitch of the partition wall, so that dimensional errors of the grid and tiles are absorbed, and the tiles arranged at arbitrary positions on the panel board can be detached. In practicing the present invention, the pitch P ₂ of the non-curved direction of the partition wall, to match the pitch of the partition walls of the grid mosaic panel plane which is generally, to allow sharing tiles Is preferred.

The pitch of the partition walls of the grid 1 is 20 to 25.
Mm, a large field <br/> if the radius of curvature R of the curved tile height is of 15 millimeters 10 to 15 meters approach distance between adjacent tiles the surface of the tile surface to be attached to the grid 0. Less than one millimeter. Therefore, a grid of curved mosaic panels, the pitch P of the pitch P ₁ of the partition wall of the bending direction non-curved direction of the partition wall
Slightly greater than 0.1 mm less than ₂
I do .

In the case of a mosaic panel having a small curved display surface whose curvature radius R is, for example, 3 to 5 meters or less , the pitch of the partition walls of the grid 1 is 2
With a mosaic panel of 0 to 25 millimeters and a tile height of 15 millimeters, the tile surface mounted on the grid is close to the adjacent tile surface by about 0.1 to 0.3 millimeters. Accordingly, the pitch of the partition walls of the grid, defining a pitch P ₁ of the partition wall of the bending direction of the non-curved direction
Than the pitch _{P 2} of the wall, and larger about 0.1 to 0.3 mm. Thereby, as shown in FIG.
A curved mosaic panel having a smaller radius of curvature can be accommodated.

[0023] In the embodiment shown in FIG. 5, the pitch P ₁ in the transverse direction of the partition wall is a curved direction, to be larger than the pitch P ₂ in the longitudinal direction of the partition wall is non-curved direction, the non-curved direction is larger than the thickness t ₁ of the lateral partition walls 3 is a curve direction and the thickness t ₂ of the partition wall 2 of a longitudinal direction.
The dimensional difference between the pitch P ₁ and the pitch P ₂ is set to be equal to the size difference between the thickness t ₁ and the longitudinal partition walls 2 thickness t ₂ of the lateral partition walls 3. Thus, a square channel 4 formed by the partition walls, can be a square having the same dimensions as squares channel grid mosaic panel plane, positive
When mounting the rectangular tiles 5, there is no trouble such as rattling or poor mounting.

The grid 1 may be integrally molded as a whole, but mosaic panels of various sizes are required. For this reason, as shown in FIG. 8, if a small grid block 13 having a side of about 30 cm, which is easy to mold, is formed and a plurality of grid blocks 13 are connected to form a large grid,
It is possible to obtain the size of the grid required easily.

The grid block 13 illustrated in FIG.
The longitudinal compartment walls 2 and intersections of the partition walls 3 in the lateral direction, thereby forming a cylindrical boss 12, an integral multiple of the pitch P ₁ of Dimensions W ₁ in the lateral direction transverse partition wall, dimensions W ₂ in the longitudinal direction is a square is an integer multiple of the pitch P ₂ in the longitudinal direction of the partition wall. The peripheral vertical partition wall 2 ′ and the horizontal partition wall 3 ′ are formed by cutting the inner vertical partition wall 2 and the vertical partition wall 3 at the center of the thickness in the plane direction. I have. Therefore, the boss 12 'having a two-part shape is provided on the peripheral partition wall, and the boss 12 having the four-part shape is provided at the four corners.
2 ". When a plurality of grid blocks are combined, the peripheral partition walls 2 'and 3' are separated from the peripheral partition walls 2 'and 3' of the adjacent grid block by an inner partition wall. While having the same thickness as 2, 3, the two-part boss 12 'and the four-part boss 12 "
Boss 12 'and boss 1 around adjacent grid block
A cylindrical boss portion is formed by the combination with 2 ″. When the connecting bolt 15 is inserted through the cylindrical boss portion formed by the combination, the adjacent grid blocks are connected to each other.

The connection structure of the grid block 13 is as follows.
This is illustrated in FIG. That is, annular projections 14 protruding outward are provided at the inner peripheral portions of both ends of the cylindrical boss 12.
And the connecting bolt 15 and the nut 16 are formed with short cylindrical portions 17 and 18 which engage with the annular projection 14. Therefore, the boss formed by the combination
Through the connection bolt 15 and screw in the nut 16
Grid blocks 13, 13 which are adjacent are connected by that.

The grid block 13 which is connected to form the large grid 1 has only a vertical or horizontal surface direction, for example, only a horizontal partition wall, curved into a curved surface having a desired radius of curvature R. The amount of deformation due to the curvature indicated by Y in FIG. 10 is approximately 1 mm when one side is 30 cm and the radius of curvature R is 12 meters.

When the grid block 13 having a deformation amount of about 1 mm is viewed alone, there is a possibility that the bending direction of the grid block 13 is mistaken. In order to avoid this, in the embodiment shown in FIG. 8, the mark 19 in the bending direction is formed integrally with the grid block by continuously connecting the four corners of the channel with a small continuous portion that can be easily separated as necessary. I have.

[0029] To manufacture the grid block 13 to bend in a certain planar direction efficiently is a plastic working capable wood charge <br/>, manufactured by molding a relatively simple planar grid blocks, This planar grid block is bent by press working. As shown in FIG. 11, the planar grid block has both ends in the bending direction fixed at the receiving pedestal 20,
20 and the intermediate part thereof is pressed and curved by a toothed die 21. The toothed die 21 is formed by projecting the pressing pieces 22 at every pitch of the partition wall in the bending direction.
The two tips are arranged on a curved surface having a desired radius of curvature R.

By manufacturing the grid block by the above method, as shown in FIG.
In addition, the boss 12 formed at the intersection of the partition walls can be avoided, and only the partition wall in the curved direction can be pressed to efficiently process. At this time, since the pressing piece 22 does not press the end surface of the boss 12 serving as the bearing surface of the tile 5,
There is no damage to the end face of the boss 12 where precise dimensional accuracy is required.

FIG. 13 is a front view of the entire grid block bending apparatus. In this embodiment, a guide rod 23 of a toothed die 21 is erected on a part of a fixed support 20 that supports both ends of the grid block 13.
A mounting base 25 of the hydraulic cylinder 24 is fixed to an upper end of the third cylinder 3. Thus, when the hydraulic cylinder 24 is extended, the pressing piece 22 of the toothed die presses the grid block 13 supported by the fixed support 20 to bend.

The tooth profile die 21 of the bending apparatus of the embodiment shown in FIG. 13 is a tooth profile die body 21 having a side plate 21b.
a and the pressing piece 22 are formed separately, and the pressing piece 22 can be advanced and retracted in the bending direction of the grid block by the adjusting screw 26, and can be fixed at an arbitrary position. The curved mosaic panel is required to have a curved surface having various radii of curvature depending on its installation location and the like. Therefore,
Although it is necessary to prepare various types of tooth dies 21 for performing curved processing of the grid, various types of curved dies are required. However, in the case where the pressing piece 22 can be advanced and retracted as in the embodiment shown in FIG. A single die can be used to bend a grid block of any radius of curvature.

In many cases, mosaic panels having a curved display surface are required to be curved in the horizontal direction. However, not only those mosaic panels which are curved in the horizontal direction but also those which are curved in the vertical direction as shown in FIG. is there. The embodiment of FIG. 9 is used as a three-dimensional control facility in a relatively narrow building or the like, and a monitoring room 27 and other computer rooms 28 are arranged on a multi-story floor. Thus, in the case of a mosaic panel that curves in the vertical direction, the grid has a vertical partition wall that is curved, and a horizontal partition wall that is not curved.

[0034]

According to the curved mosaic panel according to the first aspect of the present invention, the curved mosaic panel has a more accurate curved surface than the conventional curved mosaic panel formed by combining flat surfaces, and has a display surface excellent in visibility. can do. Further, in the curved mosaic panel according to the conventional combination of planes , the entire grid could not be connected integrally, but in the curved mosaic panel of the present invention, even when a small grid block is connected to form a large grid. In addition, the grid blocks can be continuously connected to each other so as to have excellent strength. In addition, the outer dimensions of one side
Is slightly smaller than the pitch of the non-curved compartment walls
When a square tile with dimensions is installed, it can be installed without creating an extra gap between adjacent tiles in the bending direction and without collision, and it can be seen as a panel board it can.

According to the second aspect of the present invention, while the pitch dimension of the partition walls of the grid is different between the curved direction and the non-curved direction, it is possible to maintain the grid of the grid in a square shape and to mount the grid. Versatility can be imparted to the tiles. In particular, and curved mosaic panel is a curved surface of small radius of curvature, even mosaic panel of a large grid pitch of the partition walls, it is possible to mount the tile without causing such rattling.

According to the third aspect of the invention, various sizes
The grid for curved mosaic panels, can be easily obtained by connecting many small grid blocks.

According to the fourth aspect of the present invention, a grid block which is connected to form a grid for a large curved mosaic panel can be efficiently manufactured with a constant quality and high precision by pressing a tooth-shaped die. it is, tooth die to abut only in the partition wall of the curving direction of the grid block, it is not damaging the boss portion formed at the intersection portion of the partition wall of vertical and horizontal.

According to the fifth aspect of the present invention, grid blocks having curved surfaces having different radii of curvature can be manufactured by one tooth-shaped die.
