Description

[Detailed description of the invention] projection screen array The present invention relates to a projection screen arrangement for displaying images.

The present invention is intended primarily for use in advertising and demonstration purposes; It is intended to display stills and moving images.

At the same time, advertising images, advertising films, and demonstration displays are displayed in shop windows. It is desirable to be able to display video files such as video clips, film, etc. This used to be a TV screen. Made using a clean or video player. But the TV screen is a little It cannot be seen from a distance, but it strongly attracts the attention of people who are at a certain distance from the window. It won't work if you do that.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a projection screen for viewing the display behind said screen. a projection screen that covers the entire window area or a major part thereof while allowing for The objective is to provide the following information.

According to the invention, this consists of a number of elongated sheet metal members made of cloudy translucent material. included in the screen and at a certain mutual distance within their common screen plane, their own planes (visible surfaces) at an angle with the common screen plane This is achieved by an array of projection screens characterized by the fact that . In the preferred embodiment, the il& members are such that their projections on a common plane span the entire plane. They are arranged at mutual distances and angles like barrels.

Further features of the invention are apparent from claims 3 to 9 of the appended frames. becomes.

The invention will be explained below with reference to a schematic embodiment of a screen according to the invention. Further details will be disclosed.

Figure 1 shows a screen according to the present invention in which the thin plate is inclined at 45° to the main plane of the screen. FIG. 2 is a perspective view of the clean, and FIG. 2 shows the details of the thin plate suspension part; FIG. 3 is a schematic diagram of a background projection screen according to the invention seen from above.

The projection screen 1 in FIG. 1 includes a number of thin plates 2 arranged at a distance a from each other. Ru. The laminae 2 include their longitudinal axes 3 in a common vertical plane. thin plate The members are rotatable about their axis 3, and FIG. An example of the part is shown. The thin plate member shown in FIG. 2 has a bent protrusion 4 at its upper end. It is growing.

A bottle 5 extends through a hole 6' in the upper outer flap 4' of the projection 4, with a head 6 extending from the flap. It holds the thin plate 2 in contact with the underside of the wrap 4'. Pin 5 is for example the window frame of the display window. A slide is attached to the upper frame part and is slidably arranged on the slide rail 8. It is attached to member 7. In a simple embodiment, each thin plate 2 is using a common adjustment device comprising two cords 9.10 fixed in the lower corners of the The angle of the plate member can be adjusted. Using a common member (not shown), arrow 1 The code 9.10 can be moved in the direction of 1.12.

FIG. 3 schematically shows a background projection screen 1 according to the invention, with a filter The light from the system or image projector is indicated by arrow 13. Thin plate member 2 is an opaque material In other words, they are translucent but not transparent. Therefore, When an observer stands at a certain distance from the screen while looking straight at it, An image appears on the screen, which is shown schematically by eye 14, seen by the observer on the opposite side. If screen 1 is suspended, the observer moves close to the window, he looks at the bolt of thin plate member 2 in the direction of the arrow. You can see the display 15.

Since the thin plate member 2 can slide to one side along the slide rail 8 via the slide 7, , the screen can be easily removed from the window.

Thus, with the screen according to the invention, people can view the window display while at the same time Advertising images, films, and educational films can be shown. projection screen In addition to acting as a screen, this screen can also be used as a communal sunshade. can be done. In that case, sufficient shade is achieved and at the same time the optimal *i is It is particularly advantageous to be able to arrange the lamina 2 at any desired angle so as to obtain the desired angle.
