Abstract
A combination cover and elongated friction device for holding the cover in position on a firearm is provided. The device can be used with different type guns. The cover is provided with holes and slots, for holding a bolt or hammer in a fixed position, and is shaped, to enclose the trigger or prevent movement of firearm parts, and has plural sized apertures to receive protrusion of the elongated friction device. The friction device has plural protrusions larger than the sized apertures to create an interference fit that requires specific force to remove so that there is a resistance to accidental discharge and use of the firearm by children.
Claims20
An externally attached cover in combination with a friction release device for forming a safety device for firearms comprising:
- a shaped essentially flat cover having a central section and a first side and a second side capable of being bent from said central section such that said first side and said second side can be positioned essentially parallel to each other;
- a frictionally operated release device;
- said frictionally operated release device having an elongated carrier means with a first end and a second end and a series of friction protrusions extending from said elongated carrier means between said first end and said second end;
- both said first side and said second side of said cover being provided with a sized aperture for reception of said protrusions of said frictionally operated securing device;
- said friction protrusions extending from said elongated carrier being sized and shaped to be larger than said sized apertures in said cover first side and second side to create an interference fit;
- the materials of said cover and said protrusions and the shape of said protrusions and said sized apertures and the amount of interference between said protrusions and said sized apertures being selected so as to require a predetermined force to engage and disengage said frictionally operated release device into and from said cover sized apertures.

An externally attached safety device for use with a frictionally operated securing device for firearms comprising:
- an essentially flat shaped cover having an elongated central portion and a first side and a second side extending from said elongated central portion;
- means associated with said cover first side and second side and central portion so that said cover first side and second side are capable of being bent from said central portion such that said first side and said second side are essentially parallel to each other;
- said cover being shaped and provided with a plurality of opening means adjacent said cover central portion on said cover first side for receiving parts of said firearms for preventing access to and for preventing movement of said firearm parts;
- both said first side and said second side of said cover additionally being provided with a plurality of spaced sized aperture means remote from said cover central portion and spaced from each other for passage of said frictionally operated securing device and for reception of protrusions on said frictionally operated securing device for releasably holding said cover in place on various types and shapes of said firearms and for preventing movement of a variety of said firearm parts while said cover is secured in place on said firearm.

An externally attached safety device for use with a frictionally operated securing device for firearms comprising:
- an essentially flat shaped cover having a central portion and a first side and a second side;
- means associated with said first side and said second side so that they are capable of being bent from said central portion such that said first side and said second side are essentially parallel to each other;
- said cover being shaped to provide an opening for receiving parts of said firearms for preventing movement of said firearm parts;
- both said first side and said second side of said cover having sized apertures for passage of said frictionally operated securing device and for reception of protrusions on said frictionally operated securing device for releasably holding said cover in place on said firearms;
- said cover being provided with a shaped cover extension;
- said shaped cover extension having sized apertures along one edge thereof;
- a slot in a central area of said shaped cover extension for positioning a hammer of said firearm.

An externally attached safety device for use with a securing device for firearms comprising:
- an essentially flat shaped cover having a central portion and a first side and a second side:
- said cover being semi-rigid and said cover being provided with hinge means between said first side and said central portion and between said second side and said central portion to provide for bending;
- said cover being shaped for receiving parts of said firearms for preventing movement of said firearm parts;
- said cover first side and second side having means forming inner edges that extend essentially perpendicular to said cover central portion;
- said cover first side and second side having means for forming outer edges that extend essentially perpendicular to said cover central portion and essentially parallel to said cover first side and second side inner edges;
- both said first side and said second side of said cover having sized passages for passage of said securing device;
- said sized passages in said cover first side and second side being spaced from said cover central portion a distance sufficient to permit a firearm portion to be placed there-in-between so that said securing device can be passed through said passage in said cover first side and said passage in said cover second side without interference form said firearm portion placed between said cover first and second sides;
- said cover central portion and said cover first side and second side inner edges and means for forming outer edges being spaced from each other a distance sufficient to permit said cover central portion and said cover between said inner edges and said outer edges to be placed between a firearm pump hand grip and breech when spaced apart in a firing position but said distance between said inner edges and said outer edges being insufficient to fit between said firearm pump hand grip and breech in an unextended loading position so that when said cover is placed between said firearm pump hand grip and breech in the firing position and said securing device is inserted, said cover prevents said pump hand grip from being operated to load said firearm.
