Abstract

The invention relates to an image projection device that is able to float and to fly and that comprises at least one float, projector (2) and projection surface (3). The shape and volume of the float (1) are chosen such that the lift generated by it allows for a stable position of the projector and the projection surface that are spaced apart depending on the projection distance, the projector (2) is disposed substantially outside a first peripheral surface of the float, the projection surface substantially coincides with a second peripheral surface opposite the first peripheral surface and is substantially plane when used, and that the float, between projector and projection surface has a lift-free zone which does not substantially impair the beam path in the space between the projector and the projection surface. In another embodiment, the volume of the float is chosen such that the lift generated by it allows for a stable position of the projector and the projection surface that are spaced apart depending on the projection distance, the projector is disposed substantially outside a first peripheral surface of the float, the projection surface is substantially plane when used, the projection surface is disposed in the area of a second peripheral surface that is substantially opposite the first peripheral surface of the float, and that the projection surface is fastened in the float as a separate element.

Description

technical field

[0001] The invention relates to a projection device of the generic type defined in claim 1 , capable of hovering and flying, having at least one floating body, a projector and a projection surface. Background technique

[0002] A device of this type is known from German Registered Design DE 201 11 846.7, where the projector is arranged in a fluid-filled balloon. The image projected by the projector is made visible by projecting the image onto the inner surface of the balloon casing, with the balloon as the projection surface. The image is then visible to viewers outside the balloon, which may be on the ground, hovering in the air, or rising skyward.

[0003] An understandable disadvantage of this image projection device is that, simply because of the way it is constructed, the heat generated by the projector inside the balloon will destabilize the buoyancy properties of the balloon due to the high temperature. Additionally, and primarily, disadvantages aris...

Embodiment Construction

[0038] A first exemplary embodiment of a first aspect of the present invention will be described below with reference to various views of FIGS. 1 to 6 . Figure 1 depicts a first exemplary embodiment of the invention from the front. The image projection device capable of hovering and flying includes at least one floating body 1 , a projector 2 and a projection surface 3 . According to the invention, the shape and volume of the floating body 1 can be constructed in such a way that the buoyancy generated by it can ensure the stable positioning of the projector 2 and the projection surface 3, which are located at a certain distance from each other according to the projection range. , where the projector 2 is generally arranged outside the first outer surface 4 of the floating body 1, and the projection plane 3 is substantially coincident with the second outer surface 5 of the floating body 1, which is opposite to the first outer surface 4 and It is generally flat in use. The flo...
