Sword device with retractable, internally illuminated blade
First Claim
1. An apparatus for producing an energy sword special effect, comprising:
- a hilt assembly including a drive assembly within a hilt body; and
a blade including a flexible strip with a plurality of light sources arranged in a linear pattern and an anisotropic diffuser diffusing light output from the plurality of light sources,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,wherein 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,wherein the pair of blade body members are at least partially nested to define a hollow cylindrical body of the blade, andwherein the flexible strip with the plurality of light sources is attached at an end to the end cap and is positioned within the hollow cylindrical body of the blade.

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.

15. 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 an end cap and a pair of blade body members each attached at a first end to the end cap and, when the blade is extended out from the hilt body, having a semicircular cross section in a plane orthogonal to a longitudinal axis of the blade body member, wherein the pair of blade body members are at least partially nested to define a hollow cylindrical body of the blade, 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 blade has a uniform outer diameter along its length when extended out from the hilt body. - View Dependent Claims (16, 17, 18, 19)
