The fork-shaped fitting grooves 14, 35 are formed by the ridges 35, 36 in the direction parallel and perpendicular to the sheet 3 and the connecting wall 34.
Form 14, That is, the fitting grooves 14, 14 are formed in directions orthogonal to each other.

Further, there is provided a fitting piece 16 extending to the inner end edge of the sliding contact main body 9 and a base end of the fitting piece 16 having a semicircular cross section. It has a piece 17.

On the upper and lower sides or on the left and right sides, the inner peripheral surfaces of the parallel fitting pieces 16, 16 are set to have substantially the same interval as the outer peripheral surface of the fixed frame 8. And can be freely fitted.

A female screw 30 is formed on the outer surface of the fixing frame 8, and a mounting member 31 made of aluminum or the like is attached to the female screw 30 by a bolt 33.
It is attached detachably.

The mounting member 31 has a hook-shaped locking piece 32 formed in a rolled shape along the locking piece 17 at its tip, and the mounting piece 31 is The stopper piece 32 is rotatably engaged with the stopper piece 32, and is fixed by the bolt 33.

Next, the reinforcing frame 6 comprises a vertical frame 7 and inclined arms 29, 29 connected to upper and lower ends of the vertical frame 7, respectively.

The tip 28 of the inclined arm 29,
28 is branched in an orthogonal bifurcated shape.
28 is inserted into the fitting groove 14 of the frame 2.

The inclined arm 29 of the reinforcing frame 6 has an inclination angle substantially equal to that of the inclined support piece 10.

As described above, the tip portions 28 are in contact with the two orthogonal surfaces of the connecting wall 34 and are configured to support the inner surface and the back surface of the hollow portion 12.

Next, the holder member 4 made of aluminum or the like is brought into contact with each surface of the sliding body 9 of the frame 2 so as to be slidable inward and outward.

The holder member 4 has a receiving piece 18 that is inclined rearward and outward at the tip, a flat plate 19 that contacts the sliding body 9, and a vertical section with respect to the sliding body 9. Standing piece part 20
And an engaging piece 21 having an L-shaped cross section attached to the upstanding piece 20.
have.

The tip of the hook piece 18 of the holder member 4 is formed in a circular cross section, and the hook piece 18 and the upright piece 20 are formed.
Is formed on the inner surface of the holding portion 22, and a small non-slip portion is formed on the inner surface of the holding portion 22, and a hole portion 23 for holding the tension fitting 5 is formed in the hooking piece portion 21. .

Further, the flat plate portion 19 of the holder member 4
Is slidably brought into contact with the outer surface of the sliding contact body 9, and the hole 23 of the holder member 4 and the hole of the mounting piece 11 are
The bolt of the tension fitting 5 is inserted into the fitting 24, and the nut is received in the projecting piece 26 of the mounting piece 11.

At this time, as shown in FIG. 3, a straight line G connecting the point A at the tip of the oblique receiving supporting portion and the connecting portion C of the mounting piece portion.
Rather, the point B of the holder member is set to be located outward.

The edge of the sheet 3 is wound around a round bar 27 of an appropriate length made of a fiber-reinforced composite material or the like. The sheet 3 is received at both ends of the retaining piece 21, and the round bar 27 is held by the holding portion 22.

Further, a torque screwdriver or the like is inserted in the orthogonal direction from the front, the tension fitting 5 is tightened, and the holder member 4 is pulled in the back direction along the sliding contact main body 9.
The loosened sheet 3 is stretched as shown by the solid line in FIG.

In the display panel constructed as described above, the holder member 4 is pulled in the direction of the back surface, so that the tension allowance L for stretching the sheet 3 can be increased. (Front side) Since operation can be performed more quickly and without trouble, there is no need to operate diagonally as in a conventional device, and workability is good.

Further, the point B of the holder member is set to be located outside the straight line G connecting the point A of the oblique support side and the connecting point C of the mounting piece. Thus, when the sheet 3 is stretched, the holder member 4 can be moved in a contact state with the sliding contact main body 9 without floating from the sliding contact main body 9.

Further, the tension M, N─── of the sheet 3
Since the direction of the vector H of the resultant force of the vectors ─── having different directions but having the same magnitude coincides with the direction of the oblique support piece 10, the vector H is supported by the hollow portion 12 of the frame 2. ,
The deformation of the frame 2 can be prevented.

That is, in FIG. 3, it is set so that θ ₁ = θ ₂ .

Moreover, as shown in FIG. 2, the tip portions 28, 28 of the inclined arm 29 of the reinforcing frame 6 for receiving the frame 2 are bifurcated, and are inserted into the fitting grooves 14, 14. By connecting the frames 2, the rigidity of the frame 2 can be increased on the back surface side, and the planar twist of the frame 2 can be prevented.

As shown in FIG. 4, the frame 2 is slightly loosened only at three points on the side and underside of the fixing frame 8 for replacement or inspection of the lighting and the like provided inside the fixed frame 8. The locking piece 17 and the locking piece 32 are separated from each other, and the lower side is rotated upward while only the upper surface is locked as shown in FIG.
The frame 2 can be opened (see the phantom line in FIG. 1 and FIGS. 4 and 5).

It should be noted that the present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention.

For example, the inclination angles of the oblique support pieces 10 and the oblique pieces 13 can be freely increased or decreased. Also, the holder member 4 and the round bar 27
It is also possible to freely attach the sheet 3 extending means to only the upper side and lower side of the frame 2 or only the left side and right side.

It is sometimes desirable to dispose the reinforcing frame 6 in the left-right direction to connect and reinforce the left and right sides of the frame 2.

Further, the reinforcing frame 6 is formed in a cross-girder shape.
It is also free to reinforce the left and right and upper and lower four sides.

[Effect of the Invention] The present invention is constructed as described above, and thus has the following remarkable effects.

The structure for extending the seat 3 is simple, the number of parts is small, the extension is simple, and the workability is good.

Further, the distal end portions 28 of the reinforcing frame 6 are bifurcated and inserted into the orthogonal fitting grooves 14, 14, so that sufficient reinforcement is possible, and the overall torsional rigidity of the frame 2 is reduced. , Can be up.
