Benefits of technology

[0003] The present invention involves the provision of a fan with blades for displaying an illuminated pictoral element on an exposed face of a fan blade with the light source being direct lighting and not reflected lighting from front mounted lights. At least one of the fan blades has a display device mounted thereon and operable to provide an illuminated pictoral element on a substantial portion of an exposed face of

Problems solved by technology

However, the apparatus of the mentioned patent utilized front lighting resulting in lighting the areas behind or above the fan and the message could not be changed on the blades while the fan was rotating.

Embodiment Construction

[0013] A fan, designated generally 1, is provided. The fan includes a power drive 3 to which is operably connected a fan blade system 5 comprising at least one fan blade 7 and as shown in a preferred embodiment, a plurality of blades. The drive 3 is operable to rotate the fan blade system 5 about a central axis 8 with the blades 7 moving generally in a plane. At least one of the blades 7 has an exposed face 9 viewable from the front side 10 of the fan blade system 5. In the illustrated structure, the front side 10 is generally downwardly facing when the fan 1 is a ceiling fan. It is to be understood that although a ceiling fan is described, any bladed apparatus, such as a table fan may be utilized and the front side 10 would be that portion which a person would normally see A synchronizer designated generally 12, FIG. 5, is provided to time sequential display of pictoral elements 21 on display devices 19. The synchronizer 12 may include a sensor apparatus 13 that is operable to dete...

Abstract

A fan with illuminated blades (9) for displaying pictoral elements (19) on exposed faces of the blades. The display is provided with in situ generated light in a display device (19) or from a back lighting arrangement. The fan with illuminated blades may be utilized to display static or animated messages.

Description

BACKGROUND OF THE INVENTION [0001] Associating signage, designs and / or other indicia with one or more fan blades associated with a typical ceiling fan can result in a great marketing tool for advertising a wide variety of different types of goods and services if such indicia can be easily viewed when the fan blades are in motion rotating about a central axis. Such a device may be found in U.S. Pat. No. 6,213,617. Prior to the just mentioned patent, such indicia was imprinted directly onto a plurality fan blades or onto fan blade covers associated with a particular ceiling fan but was not clearly visible when the fan blades were in motion due to the rotational speed of the ceiling fan. As disclosed in U.S. Pat. No. 6,213,617, an advance in the art was provided by front illumination of the fan blades and message thereon freezing the motion of the blades through the use of strobe lighting or other suitable lighting timed to illuminate a fan blade at a particular rotational position. Th...
