Abstract
Abstract A block made of a resilient material is molded to conform to the inner perimeter of a gun trigger guard. The trigger is held in a depressed state when the block is inserted. The block has flexible flanges formed on both sides which partially extend around the trigger guard and the depressed trigger to hold the block in place. At the approximate center, where the undepressed trigger would normally be, a simulated trigger is formed so as to appear to be part of the weapon. The trigger block is colored so it appears to be part of the weapon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
60 words
A quick-release trigger safety device for a gun having a trigger and a trigger guard with an inner perimeter comprising: a resilient block formed to closely fit the inner perimeter of said trigger guard with said trigger depressed having a flange on each of two sides of said block extending beyond said inner perimeter to hold said block in place.
Claim 2
Dependent Claim
60 words
A quick-release trigger safety device for a gun having a trigger and a trigger guard with an inner perimeter comprising: a resilient block formed to closely fit the inner perimeter of said trigger guard with said trigger depressed having a flange on each of two sides of said block extending beyond said inner perimeter to hold said block in place.
Claim 3
Dependent Claim
50 words
A quick-release trigger safety device as in claim 1 wherein said resilient block comprises two broad flat surfaces and a narrow surface having a thickness approximately equal to the thickness of said trigger guard perpendicular to said broad flat surfaces, said flanges extending beyond both sides of said narrow surface.
Claim 4
Dependent Claim
28 words
A quick-release trigger safety device as in claim 1 wherein a simulated trigger is formed at the approximate location where said trigger would be in an undepressed state.
Claim 5
Dependent Claim
44 words
A quick-release trigger safety device as in claim 1 wherein a flat diaphragm is disposed in a portion of said broad flat surfaces between said simulated trigger and the front of said block so that said block will partially collapse for insertion or removal.
Claim 6
Dependent Claim
26 words
A quick-release trigger safety device as in claim 1 wherein said resilient block comprises a resilient rubber-like material colored to match the color of said gun.
Claim 7
Dependent Claim
42 words
A quick-release trigger safety device as in claim 1 wherein said flange collapses when pressed against said trigger guard upon attempted insertion of said block and resiles to said flange's original configuration when said block is fully seated within said trigger guard.
Claim 8
Dependent Claim
41 words
A quick-release trigger safety device as in claim 1 wherein said flange collapses when pressed against said trigger guard using sufficient pressure upon attempted removal of said block and resiles to said flange's original configuration when said block is fully removed.
Claim 9
Dependent Claim
26 words
A quick-release trigger safety device as in claim 4 wherein ridges are disposed on said flat diaphragm to provide a friction surface for the user's thumb.
