Ejection device to expel objects from the inside of a bag in the event of a bagsnatching

An ejection device for a bag to expel objects from the inside of the bag in the event of a bag-snatching, the bag comprising internally an expandable sack provided with a compressed gas feeder so that the expandable sack is inflated from a wait condition wherein it is empty to an operated condition wherein the expandable sack is inflated to a volume greater than the internal volume of the bag, said bag ejection device comprising:

• a lining (400) removably held with its upper hem near the edge of the opening of a bag (100;
• 103);
• an expandable sack (1) arranged on a base (102) of the bag (100;103) below the lining (400);
• a compressed gas feeder (2) disposed below the expandable sack (1) and which includes a small gas bottle (6) having a pierceable mouth;
• an elongated housing (20) connected at a front part to the small gas bottle (6) and on an upper part to the expandable sack (1), said housing including a piercing element (7) having a bid (72) provided with an axial passageway (73) communicating with said expandable sack (1) through its hollow cylindrical body (70) which has rear ports (76) and is axially movable by the pressure of spring (84);
• a release mechanism (8) for releasing spring (84) to push the piercing element (7), having an ogival release member (86) removably retained by means of at least a retaining flexible thin plate (88) to a cylindrical body (81) in abutment upon an end wall (24) of the housing (20) opposed to the small gas bottle (6) and small balls (80) which are at the same time housed in said ports (76) of the hollow body (70) and in a circumferential groove of said cylindrical body (81), so that, when the ogival release member (86) is moved away from the contact with the small balls, hollow body (70) disengages from cylindrical body (81) releasing the piercing element (7) against the pierceable mouth of the small gas bottle (6);
• means (3) for controlling said release mechanism (8) comprising a bowden cable transmission (30), having at one of its ends a connection to the release member (86) and at another end a junction member to a portion of a bag (100;
• 103) designed to be held by the wearer of the bag, so that a snatch, being transmitted to said portion of the bag through the bowden cable transmission (30), operates the release mechanism (8) and causes the expandable sack to be inflated until the lining is completely overturned.
