Abstract

PROBLEM TO BE SOLVED: To provide a frameless screen, on which bright images can be viewed by generating irregular reflections by thickening the plate of a screen part at image projection and the images can be viewed, as through they are in relief by removing an outer frame from the screen at the time of the image projection. SOLUTION: The lower side of a reinforced opal translucent acrylic thin plate which is to be an image projection part is supported tightly by the upper side of a transparent acrylic board thin plate at an upper part, the entire front and back surfaces of the opal translucent acrylic thin plate and the transparent acrylic board thin plate are clamped by an outer side transparent acrylic board, so that a clamped plate is obtained. The lower side outer peripheral edge of the clamped plate is supported by a supporting leg.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frameless screen projected at a conference, a wedding hall, or a funeral home, and more particularly to a transmission screen having no outer frame.

[0002]

2. Description of the Related Art Conventionally, in a transmission type rear screen,
The entire screen was surrounded by an outer frame, and thus, when projected, the image was constrained within this frame to project within that frame, thereby giving the viewer a cramped feeling.

[0003]

In the conventional screen, since the image is projected on the screen with the frame, the screen image gives the viewer a sense of restraint and cramp. In addition, there is also a drawback that a thin screen with a frame cannot be seen brightly.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. It is an object of the present invention to increase the thickness of a screen portion so that an image can be viewed brightly due to diffuse reflection generated during image projection. It is an object of the present invention to provide a frameless screen in which an image is raised when an image is projected by removing an outer frame from the frame.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and has a lower side of a reinforced milky white translucent acrylic thin plate which is an image projection section on the upper side and is closely supported by an upper side of the transparent acrylic thin plate. By sandwiching the entire front and back of the milky white translucent acrylic thin plate and the transparent acrylic plate thin plate with the outer transparent acrylic plate as a whole, it becomes a firm holding plate, and the lower peripheral edge of the lower side of the holding plate as a support leg. Supported.

The thickness of the reinforced milky translucent acrylic thin plate is 1 mm to 2 mm, and the thickness of the transparent acrylic thin plate is 5 mm to 10 mm.

Further, each of the support legs is provided with a plurality of casters.

[0008]

Embodiments and examples of the present invention will be described below with reference to the drawings. The lower side of the reinforced milky white translucent acrylic thin plate 1 having a thickness of 1 mm to 2 mm serving as an image projecting section on the upper side has a thickness of 1 mm to 2 mm.
mm transparent acrylic plate thin plate 2 is tightly supported on the upper side thereof, and the entire front and back of the milky white translucent acrylic thin plate 1 and the transparent acrylic plate thin plate 2 are sandwiched between outer transparent acrylic plates 3 and 3 having a thickness of 5 mm to 10 mm. A dressing plate a is configured. That is, in the upper part, the front and back outer transparent acrylic plates 3, 3,
It is composed of three layers of a reinforced milky white translucent acrylic thin plate 1 which is an intermediate layer sandwiched between the outer transparent acrylic plates 3 and 3,
Furthermore, in the lower part, the front and back outer transparent acrylic plates 3, 3
And a transparent acrylic thin plate 2 which is an intermediate layer sandwiched between the outer transparent acrylic plates 3 and 3.
Accordingly, the holding plate a is a strong holding plate a as a whole. Therefore, the upper portion of the sandwiching plate a is a milky white translucent acrylic thin plate 1 and the screen composed of the transparent acrylic plates 3 and 3 can be effectively used as a rear screen.

An outer peripheral edge of a lower side of the holding plate a is supported by supporting legs b including a frame plate 4, legs 5, and casters 6 provided at both ends of the legs 5.

The image projecting portion is an upper area of the reinforced milky white translucent acrylic thin plate 1 having a thickness of 1 mm to 2 mm. When an image is projected on this area, irregular reflection is caused by the outer transparent acrylic plates 3, 3 having a thick transparent plate. As a result, the image is projected brightly, and the lower part of the image projection part is transparent, so that the projected image appears to be raised.

[0011]

According to the frameless screen of the first aspect, the lower side of the reinforced milky white translucent acrylic sheet serving as the image projection section is closely supported on the upper side of the transparent acrylic sheet thin sheet at the upper portion, and this milky white translucent acrylic thin sheet and transparent The entire front and back of the acrylic plate is sandwiched by the outer transparent acrylic plate to form a sandwiching plate, and the outer peripheral edge of the lower side of the sandwiching plate is supported by support legs, so it is lightweight overall and easy to handle It has a convenient weight. Further, since there is no frame plate around the projected image portion and the lower portion is transparent, when the image is projected on the reinforced milky translucent acrylic thin plate which is the image projected portion of the present invention, the projected image Because it appears to be raised, those who watch it can feel more open than a conventional screen with a frame. Moreover,
The reinforced milky white translucent acrylic thin plate, which is the image projection portion, is sandwiched between the outer transparent acrylic plates at the portion and has a large thickness. In the frameless screen according to claim 2, the thickness of the reinforced milky white translucent acrylic thin plate is 1 mm to 2 mm, and the thickness of the transparent acrylic thin plate is sandwiched between 5 mm to 10 mm, so that the overall weight is light, It is possible to provide an inexpensive frameless screen that is convenient to handle. Claim 3
In the frameless screen described above, the support legs are provided with a plurality of casters, respectively, so that they can be easily moved in any direction.
