Claims
What is claimed is:
1. A trigger safety device for guns having a trigger with a space
behind said trigger, comprising a resilient plug of irregular shape
that fits in the said space conforming to the shape of said space
and slightly larger than said space so as to be compressed when
positioned in said space.
2. A trigger safety device as in claim 1 in which said safety
device is held in place by its bodily resilience.
3. A trigger safety device as in claim 1 wherein said resilient
plug has two broad, flat surfaces and narrow surfaces perpendicular
to said broad, flat surfaces.
4. A trigger safety device as in claim 1 wherein said resilient
plug has two broad flat surfaces and narrow surfaces perpendicular
to said broad flat surfaces, said narrow surfaces having a convex
shape.
5. A trigger safety device as in claim 1 wherein said resilient
plug has two broad, flat surfaces and narrow surfaces perpendicular
to said broad flat surfaces, one of said broad flat surfaces having
an extended edge extending beyond said narrow surfaces.
Description
BACKGROUND OF THE INVENTION
This invention relates to a trigger safety device which is
inexpensive and simple to use. It is especially adapted for use on
police guns where the danger of the gun being snatched from the
policeman's holster and used against him is a serious one. The news
media often tell of a criminal snatching a policeman's revolver
from his holster and using it on the policeman and others with
tragic results.
In addition, the present invention prevents the accidental
discharge of a firearm in case of accidental dropping of the gun.
Also the device of the present invention will usually prevent
accidental discharge when a gun falls into the hands of a small
child.
The principal object of the present invention is to minimize or
prevent the accidental discharge of firearms.
Another object of the present invention is to accomplish these
results in a simple and inexpensive manner while not interfering
with quick draw and use of the pistol by the policeman.
The problem of providing a trigger safety device which will not
conflict with the quick use of the firearms by the policeman has
been solved by the present invention. This problem has not been
overcome by the prior art.
There have been many devices proposed for the same general purpose.
They usually involve complex locking devices or guards which are
both expensive and would seriously interfere with for example a
police officer attempting to use his handgun. The following prior
art United States Patents show the complexity and expense of the
prior art devices:

DESCRIPTION OF DRAWING
FIG. 1 is an overall elevation view of a typical 38 caliber police
revolver with my trigger safety device in place.
FIG. 2 shows an elevational view of one form of my trigger safety
device, in cross section along line 2--2.
FIG. 3 is a perspective view of one form of my trigger safety
device.
FIG. 4 is a perspective view of another form of my invention.
FIG. 5 is a perspective view of still another form of my
invention.
DESCRIPTION OF PREFERRED EMBODIMENT
In the drawing in which like reference numerals designate like
parts throughout the drawing, the body of a typical 38 caliber
police revolver is designated 1. The trigger 2 is surrounded by
trigger guard 3.
My trigger safety device 4 is a plug preferrably made of a
resilient substance preferably a medium-soft rubber or plastic
material. The form of my invention shown in FIG. 3 has narrow
surfaces 9, perpendicular to two broad surfaces 10. The size of the
safety device 4 is such as to fit snugly between trigger 2 and
trigger guard 3 so that safety device 4 is compressed when in
position so that it will stay firmly in position. Nevertheless the
firmness must not be such as to interfere with the police officer
being able to quickly push the safety device 4 out of the trigger
guard 3 so as to be able to promptly use the gun.
This ability to promptly remove the safety device so as not to
interfere with its use is an important advantage of the present
invention over the prior art.
The form of my safety device shown in FIG. 4, has two broad, flat
surfaces 5 and relatively perpendicular smaller surfaces 6 having
slightly convex shape as shown.
In the form of my safety device shown in FIG. 5, the two broad,
flat surfaces 7 and relatively perpendicular surfaces 11 both are
relatively flat, however, one of surfaces 7 has an extended edge 8
extending slightly beyond surfaces 11 which enables the device to
be pushed out of the gun in the direction shown by the arrow in
FIG. 5 only and not in the opposite direction. This form of the
invention would be made specifically for use by either left-handed
or right-handed policemen, but the same form could not be used by
both.
