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. In front of the simulated trigger is an opening into which the trigger finger may be inserted in a normal manner, promoting the appearance of the block as being part of the weapon, disguising the fact that the weapon has been disabled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A quick release trigger safety device for a gun having a trigger guard with an inner perimeter comprising: a resilient block formed to closely fit said inner perimeter of said trigger guard with the gun's trigger depressed having a flange on each of two sides of said block extending beyond said inner perimeter to hold said block in place, an opening having front and rear edges disposed at the center of said block, said opening being sufficiently large to permit insertion of a user's trigger finger, and a simulated trigger formed at the rear edge of said opening.
Claim 2
Dependent Claim
98 words
A quick release trigger safety device for a gun having a trigger guard with an inner perimeter comprising: a resilient block formed to closely fit said inner perimeter of said trigger guard with the gun's trigger depressed having a flange on each of two sides of said block extending beyond said inner perimeter to hold said block in place, an opening having front and rear edges disposed at the center of said block, said opening being sufficiently large to permit insertion of a user's trigger finger, and a simulated trigger formed at the rear edge of said opening.
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
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 the block will partially collapse for insertion or removal.
Claim 5
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 6
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 resides to said flange's original configuration when said block is fully seated within said trigger guard.
Claim 7
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 resides to said flange's original configuration when said block is fully removed.
Claim 8
Dependent Claim
28 words
A quick-release trigger safety device as in claim 1 wherein said simulated trigger is formed at the approximate location where said trigger would be in an undepressed state.
Claim 9
Dependent Claim
26 words
A quick-release trigger safety device as in claim 3 wherein ridges are disposed on said flat diaphragm to provide a friction surface for the user's thumb.
