Description

[Detailed description of the invention] The present invention relates to an improvement of a foldable sea tool display hood including a pyramidal part formed by combining a number of trapezoidal cover plates. The hood had defects such as the shape-retaining force of the pyramidal part not necessarily being sufficient and the appearance being poor.

The present invention attempts to eliminate such defects by using a folding method, and is a foldable sheet that includes a pyramidal portion formed by combining a large number of trapezoidal cover plates. R.T. Display hood main body, inserting pieces connected to the front edge of each cover via bendable lines, and each corner including one of these inserting pieces as one side. A shape-retaining frame that can be bent freely, and the remaining clamping pieces mentioned above, which are connected to the front edge of each piece of the shape-retaining frame except for the one side mentioned above, via a bendable line, are rolled up. The gist is that it is composed of a rolling piece that maintains the shape of the pyramidal part, and a locking tool that maintains each rolling piece in a rolled-up state.

In the illustrated embodiment, a cowhide-like synthetic leather 2 is attached to a thin core plate 1 made of hard plastic, and a rectangular cylindrical mounting frame 3 that is slightly larger than the outer circumference of the screen A and is bendable at the four corners is formed. A narrow fixing plate 5 is attached to the rear edge of each side of this mounting frame 3 via a bendable line 4.
A double-sided pressure-sensitive adhesive tape 6 is attached to the outer surface of each fixing plate 5 with a release sheet 7 attached to the outer surface thereof, and a core-less adhesive tape is attached to the rear edge of the upper side of the mounting frame 3. A wide hanging piece 9 is provided, and a pair of male and female velcro fittings 10, 10' are attached to the back side of both sides of the upper edge of the hanging piece 9.
0 is attached in a removable state, and a double-sided pressure-sensitive adhesive tape 12 is attached to the back surface of the female side fitting 10 with a release sheet (not shown) attached to the outer surface thereof.

Separately from the above-mentioned mounting frame 3, a rectangular cylinder whose inner diameter is the same as the outer diameter of the mounting frame 3 and whose four corners are bendable is made by wrapping cowhide-like synthetic leather 16 on a thin core plate 15 made of hard plastic. A fixed frame 17 is constructed, and the rear edge of the fixed frame 17 is connected to the outer periphery of the mounting frame 3 in a separable fitting manner.

Furthermore, separately from the mounting frame 3 and the fixed frame 17, cowhide-like synthetic leather 20 is attached to a thin core plate 19 made of hard plastic, so that the four corners whose inner diameter is the same as the outer diameter of the fixed frame 17 are bendable. This movable frame 21 is connected to the outer periphery of the fixed frame 17 by a telescopic and separable fitting method, and the front edges of the upper, lower, left and right sides of the movable frame 21 are connected to the outer periphery of the fixed frame 17. Trapezoidal cover plates 22, 23, 24 with similar core plates,
25, and the top, bottom, left, right, etc. covered version 2
Insertion pieces 22', 23', 24', 25' each having a similar core plate are integrally connected to the front edges of 2, 23, 24, 25 via bendable lines 26, 27, respectively. Among these, the upper fitting piece 22' is a shape-retaining frame 28 whose four corners including the piece 22' as one side are bendable, and each piece 29, 30 excluding the upper side of this shape-retaining frame 28,
Roll-up pieces 33, 34, and 35 that can be folded into two are connected to the front edge of 31 via a bendable line 32, and the inner surface of the tip edge of each of these roll-up pieces 33, 34, and 35 and the lower surface of the above-mentioned Cover version 23 and left and right double-sided cover version 24,
The inner surface of the tip edge of 25 has the same rolled-up pieces 33, 34,
By attaching locking tools 36, 36' made of magic tape that engage with each other and maintain the rolled-in state when the screw 35 is rolled up, and by bringing these locking tools 36, 36' into an engaged state. Top, bottom, left and right cover version 22,2
3, 24, 25 are kept in the shape of a pyramid, and a polarizing filter 38 in the form of a quadrilateral plate is placed in the fixed frame 17.
It is fitted tightly so that it can be removed.

That is, when installing this on the large screen A of the display, as shown in Fig. 4, the mounting frame 3 is fitted on the outside of the screen A with the fixing plate 5 tilted inward. At the same time, the hanging piece 9 is fixed to the display body using the fixtures 10 and 10' attached to the same piece 9. If the screen A is small, the hanging piece 9 is fixed to the display body as shown in Fig. 5. This is done by raising the printing plate 5 and attaching it to the outer periphery of the screen using the pressure-sensitive adhesive tape 6, and fixing the hanging piece 9 to the display body in the same manner as above. In some cases, the fixing frame 17 is removed from the mounting frame 3, and in other cases, such as transportation or packaging, the whole is disassembled and crushed as shown in Figures 2 and 3 to make it into a small, bulky state. In addition, if it is desired to adjust the length of the body portion that performs the light shielding function, the movable frame 21 may be moved back and forth along the fixed frame 17.

As mentioned above, the present invention consists of a foldable CRT display hood body including a pyramidal part formed by combining a large number of trapezoidal cover plates, and a foldable hood body for a CRT display, which is made up of a plurality of trapezoidal cover plates. Insertion pieces connected together via bendable wires, a shape-retaining frame whose each corner is bendable and including one of these insertion pieces as one side, and the above-mentioned shape-retention frame in the shape-retention frame. A clamping piece that is connected to the front edge of each piece except for one side via a bendable line and that retains the shape of the pyramidal part by rolling up the remaining clamping pieces, and a clamping piece that retains the shape of the pyramidal part; Since it is comprised of a locking tool for maintaining the shape of the pyramid, it not only has an excellent shape-retaining force and good appearance, but also has practical effects such as being easy to disassemble and assemble, and easy to use.
