Abstract
Abstract A hand held device for activating a chemiluminescent wand of the type having a first chemical fluid in a flexible tube and a second chemical fluid in a frangible tube within the flexible tube, the apparatus has a bracket formed to retain one end of the wand, a lever portion extending obliquely from the bracket and designed to fit into the user''s palm, and a fulcrum portion on the bracket which cooperates with the lever portion to thereby fracture the frangible tube in the wand causing the first chemical fluid to mix with the second chemical fluid and generate a chemiluminescence.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
Apparatus for activating a chemiluminescent wand having a first chemical in an inner frangible tube and a second chemical in an outer flexible casing encompassing the inner tube, the apparatus comprising: a bracket for restraining one end of the wand, and allowing the other end of the wand to extend free from the bracket, the bracket including a fulcrum portion which bears against the wand intermediate its opposite ends, and a lever arm rigidly connected to the bracket and extending toward the free end of the wand, the lever arm, the fulcrum portion and the free end of the wand all residing in the same plane, whereby a user of the apparatus activates the wand by squeezing together the free end of the wand and the lever arm thereby bending and fracturing the inner frangible tube of the wand over the fulcrum portion and generating chemiluminescence.
Claim 2
Dependent Claim
146 words
Apparatus for activating a chemiluminescent wand having a first chemical in an inner frangible tube and a second chemical in an outer flexible casing encompassing the inner tube, the apparatus comprising: a bracket for restraining one end of the wand, and allowing the other end of the wand to extend free from the bracket, the bracket including a fulcrum portion which bears against the wand intermediate its opposite ends, and a lever arm rigidly connected to the bracket and extending toward the free end of the wand, the lever arm, the fulcrum portion and the free end of the wand all residing in the same plane, whereby a user of the apparatus activates the wand by squeezing together the free end of the wand and the lever arm thereby bending and fracturing the inner frangible tube of the wand over the fulcrum portion and generating chemiluminescence.
Claim 3
Dependent Claim
22 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the bracket and lever arm are made of a transparent material.
Claim 4
Dependent Claim
44 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the bracket further comprises a clip attached to the bracket and oriented in a plane parallel to the plane containing the lever arm, the free end of the wand and the fulcrum portion.
Claim 5
Dependent Claim
35 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the bracket further comprises at least one flexible loop around the restrained wand end, and means for removably engaging the loop to the bracket.
Claim 6
Dependent Claim
48 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the wand has a pair of integrally formed, projecting barbs at one end and the bracket has a pair of spaced apart holes for receiving and engaging the barbs to secure the one end of the wand.
Claim 7
Dependent Claim
30 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the lever arm is flat and is rigidly connected to one side of the bracket at an oblique angle.
Claim 8
Dependent Claim
28 words
A chemiluminescent wand activating apparatus as recited in claim 1 wherein the lever arm is ell shaped and is rigidly connected to the bracket beneath the fulcrum portion.
