Sword device with retractable, internally illuminated blade
First Claim
1. An apparatus for producing an energy sword special effect, comprising:
- a hilt body;
a drive assembly mounted to the hilt body;
a blade member storage within the hilt body; and
a blade including a flexible strip with a plurality of light sources,wherein the drive assembly operates in a first operating state to mechanically extend the blade outward from the blade member storage via an opening in the hilt body and in a second operating state to mechanically retract the blade into the blade member storage in the hilt body through the opening in the hilt body,wherein the plurality of light sources is powered on during the first operating state to output light from the blade, andwherein the blade comprises an end cap and a pair of blade body members each attached at a first end to the end cap and having a semicircular cross section in a plane orthogonal to a longitudinal axis of the blade body member.

Abstract
A special effects device for providing an energy sword effect. The device includes two long plastic semi-cylinders, and these two blade body members are rolled perpendicular to their length, which creates compact cylinders of material of small volume that can be provided on a pair of spools in a hilt. To extend the blade, a motor provided in the hilt unrolls the blade body members from the spools. Each blade body member passes through a blade forming guideway that nests the semi-cylindrical blade body members together as they leave the hilt. To retract the blade, the process is reversed. The lighting of the blade is achieved with a flexible strip of light sources. The light source strip is attached to a blade end cap and positioned in the center of the two blade body members such that it is pulled up along with the blade body members during their extension.

9. A special effects device, comprising:
-
a hilt body; a drive assembly; an end cap; a pair of blade body members each attached to the end cap; and a plurality of light sources, wherein the drive assembly operates in a first operating state to provide motorized extension of the blade body members outward from an opening in the hilt body and in a second operating state to provide motorized retraction of the blade body members into the hilt body through the opening in the hilt body, wherein the plurality of light sources is positioned between the pair of blade body members and are powered to output light when the drive assembly is operated in the first operating state, wherein each of the blade body members has a planar cross section in a plane orthogonal to a longitudinal axis of the blade body member when the blade body member is retracted into the hilt body, and wherein the hilt assembly includes a blade shaping assembly shaping the blade body members into the planar cross section during retraction of the blade into the hilt body and into a semicircular cross section during extension from the hilt body. - View Dependent Claims (10, 11, 12, 13)

14. An apparatus for producing an energy sword special effect, comprising:
-
a hilt assembly including a drive assembly within a hilt body; and a blade comprising a pair of blade body members each having, when the blade is extended out from the hilt body, a semicircular cross section in a plane orthogonal to a longitudinal axis of the blade body member, wherein the drive assembly operates in a first operating state to extend the blade outward from an opening in the hilt body and in a second operating state to retract the blade into the hilt body through the opening in the hilt body, and wherein the pair of blade body members are at least partially nested when the drive assembly is operated in the first operating state to define a hollow cylindrical body of the blade. - View Dependent Claims (15, 16, 17, 18)
