ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
This invention relates to display devices and more particularly to a wall mountable display device which provides a pair of separate single intact images which can be observed by looking at the display device from different oblique angles.
2) Description of the Prior Art
Previously, it has been known to construct wall hangings such as posters or pictures which have been created using a corrugated surface which present different information or pictorial displays depending upon the angle from which the poster or picture is viewed. Each image is created by a series of strip-like panels that are mounted parallel to each other. The panels forming one image are arranged perpendicular to a direction of observation which is oblique to the plane of the base. Observing of one image from its observable direction results in only one of the images being visible while the other image is hidden from view. Changing of the observable direction by ninety degrees will result in the second image being observable and the first image then being hidden from view. In other words, the double image poster or picture of the prior art consists of two different images with the panels of each image being placed in alternate spaces between successive folds in a pleated base with the pleats being at an even pitch and mutually parallel.
Such dual image pictures of the prior art have not achieved great popularity. One of the reasons for this lack of popularity is that the poster is constructed not as a poster but is actually a framed picture being of a fixed size. Fixed size pictures are difficult to handle and makes costly the transporting of the framed picture to a gallery or store for marketing. If the picture could be constructed as a poster and was designed to be collapsible so that it could occupy substantially less space facilitating transporting prior to marketing, then possibly the poster could achieve a greater degree of popularity mainly because the poster is able to be sold at a lower cost.
SUMMARY OF THE INVENTION
A collapsible double image poster which is formed of a sheet material base which is of a basic polygonal configuration and has a base plane. Incorporated within the base plane are a series of pleats which are formed in a corrugated manner. Each pleat has a right planer panel and a left planer panel. The base is to be normally constructed of paper and capable of assuming a collapsed position with the pleats located essentially in a narrow or abutting relationship. The base can then be expanded with a pair of dowel rods mounted in a crossed manner on the back side of the base with the ends of the rods located within rod supporting brackets mounted on the base. The base has now assumed an extended position with the right planer panel and left planer panel of each pleat assuming a right angle. Observation of the base at an oblique angle and observing of the right planer panel of each pleat in the straight on direction will result only in the right planer panels being observed and not the left planer panels. Observation at an oblique angle and ninety degrees spaced from the first observation direction will result in observing of only the left planer panels of each pleat and eliminating of the observation of the right planer panels.
The primary objective of the present invention is to construct a piece of art in the form of a poster or picture that includes a double image with each image being observable individually depending upon the direction of observance of the poster.
Another objective of the present invention is to construct a double image poster that can be collapsed facilitating transportability and storage of the poster prior to usage.
Another objective of the present invention is to construct a double image poster which can be easily expanded to its usage position and mounted in that expanded position not requiring any special skill or special tools.
Another objective of the present invention is to construct and cut the paper of the poster in such a way that it forms an extension to allow the finished piece to “float” from the wall.
Another objective of the present invention is to construct a double image poster which can be manufactured at a relatively inexpensive price and thereby sold to the ultimate consumer at an inexpensive price.
