HOLOGRAPHIC STATUE WITH AN AUTO-SWITCH MECHANISM

STATUE HOLOGRAPHIQUE A MECANISME AUTOCOMMUTATEUR

English Abstract

.cndot. A holographic projection device for displaying a 3-dimensional
image
comprises a cylindrical base having a diagonally-cut top portion, and a
figurine. The cylindrical base comprises a reflection-type hologram, a
point source of white light, and a magnetic element. The figurine has a
diagonally-cut bottom portion, and comprises a magnetic element. The
reflection-type hologram projects an upright orthoscopic image having
both horizontal and vertical parallaxes. The cylindrical base has the
capability of detachably mounting the figurine with a magnetic attraction
force between the magnetic elements. A downward movement of the magnetic
element by gravity turns on the point source of white light when the
figurine is detached. An upward movement of the magnetic element turns
off the point source of white light when the figurine is magnetically
attached. This invention relates to holographic projection devices for
displaying a 3-dimensional image, and the principal use of the invention
is for optical decoration.

French Abstract

Dispositif de projection holographique servant à afficher une image tridimensionnelle. L'invention comprend une base cylindrique ayant une partie supérieure coupée en diagonale et une figurine. La base cylindrique comprend un hologramme de type réflexion, une source ponctuelle de lumière blanche et un élément magnétique. La figurine comporte une partie inférieure coupée en diagonale et comprend un élément magnétique. L'hologramme de type réflexion projette une image orthoscopique ayant des parallaxes tant horizontales que verticales. La base cylindrique est en mesure de fixer sur la figurine, de façon amovible, une force d'attraction magnétique entre les éléments magnétiques. Un mouvement vers le bas de l'élément magnétique, par gravité, fait tourner la source ponctuelle de lumière blanche lorsque la figurine est détachée. Un mouvement vers le haut de l'élément magnétique détourne la source ponctuelle de lumière blanche lorsque la figurine est fixée de façon magnétique. Cette invention concerne des dispositifs de projection holographique servant à afficher une image tridimensionnelle et la principale utilisation de l'invention est à des fins de décoration optique.

Description
Title
= Holographic Statue with an Auto-Switch Mechanism
Technical Field
= This invention relates to holographic projection devices for displaying a

3-dimensional image, more particularly to a holographic projection device
for displaying a 3-dimensional image of a statue.
Background Art
= There are many instances where it would be desirable to be able to have a
compact holographic projection device for displaying a 3-dimensional
image such as a statue, in which a figurine is magnetically mounted.
= A number of patents disclose holographic projection devices with
different configurations for displaying holographic images.
= Canadian Application 2 277 653 discloses a "Cylindrical Holographic
Display Device" for displaying an upright holographic image
perpendicularly to the hologram. However, this prior art suffers from a
limited viewing angle, and a small height of the upright holographic
image.
= Canadian Application 2 278 110 discloses a "Holographic Display Device
with a Paraboloidal Hologram" for displaying an upright holographic image
perpendicularly to the hologram which has a wider viewing angle. However,
this prior art applies only to transmission-type holograms, and is too
complex and difficult to manufacture.
= Canadian Application 2 289 999 discloses "Holographic Statue Projection
Device" for displaying an upright holographic image diagonally to the
hologram which has a much wider viewing angle.
= These prior art arrangements do not provide a figurine which is
magnetically mounted on a cylindrical base in order to superimpose with
the 3-dimensional holographic image of a reflection-type hologram on the
cylindrical base.
Description of the Invention
= It is a primary object of the invention to provide a holographic
projection device for displaying a 3-dimensional image having both
horizontal and vertical parallaxes.
= It is another object of the invention to provide a holographic projection

device with an elliptical reflection-type hologram placed diagonally in
order to provide a wide viewing angle.
= It is another object of the invention to provide a holographic projection

device with a figurine which has the same shape and the same size as the
holographic image of a reflection-type hologram.
= It is another object of the invention to provide a holographic projection

device with a figurine which detachably mounts on a cylindrical base with
a magnetic attraction force.
= It is another object of the invention to provide a holographic projection

device with magnetic elements which turn off and on an electrical circuit
when a figurine is attached to or detached from a cylindrical base.
= A holographic projection device for displaying a 3-dimensional image
comprises a cylindrical base having a diagonally-cut top portion, and a
figurine. The cylindrical base comprises a reflection-type hologram, a
point source of white light, and a magnetic element. The figurine has a
diagonally-cut bottom portion, and comprises a magnetic element. The
reflection-type hologram projects an upright orthoscopic image having
both horizontal and vertical parallaxes. The cylindrical base has the
capability of detachably mounting the figurine with a magnetic attraction
force between the magnetic elements. A downward movement of the magnetic
element by gravity turns on the point source of white light when the
figurine is detached. An upward movement of the magnetic element turns
off the point source of white light when the figurine is magnetically
attached.
