ABSTRACT:
This invention relates to an ejection device to expel objects from the inside of a bag in the event of a bag-snatching.
The same applicant has filed a PCT patent application for a self-emptying bag before. Such a bag, in general a bag with a handle or a shoulder-strap, has an inner expandable sack that, when empty, is located on the bottom of the bag. A couple of ties are provided in the handle or the like among the end of the handle and a couple of fuses respectively connected to containers of compressed gas or air. These gas containers are connected to the expandable sack in the opposite direction with respect to the fuses. When a handbag-snatcher tries to snatch such a bag by pulling away either the bag handle or the same bag from a person wearing the bag, the ties activate the fuses in order that gas is fed from the containers into the expandable sack. The expandable sack, being inflated by the gas to a volume greater than the volume of the bag, expels objects in the bag from the inside of the bag to outside.
According to the patent application above cited, means known at that time could be used to manufacture the self-emptying bag. In particular, the existing feeders of compressed air or gas, that are provided e.g. on self-inflatable life-jackets, according to how they are designed, have a very slow operation in any case. This very slow operation is not suitable for the fast ejection that is required to spread quickly on the ground all the contents of a bag of a person being bag-snatched.
Further, according to the patent application above cited a generic weakness means of either the handle or the shoulder-strap is provided. Thus, it is necessary to develop weakness means which does not weaken the handle or the like but allows the handle to be quickly separated into two sections and next to be restored back into its original form readily and integrally.
In general, conventional means, which the bag according to the patent application known is provided with, then cause a not satisfactory operation of the bag.
Therefore, a main object of this invention is to allow an effective operation of a self emptying bag with respect to the fast inflation of the expandable sack and the subsequent complete ejection of the contents from the bag. Another object of this invention is to allow a safe release of a shoulder-strap or the like so that a person, when bag-snatched, does not suffer also physical damages.
According to this invention there is provided an ejection device to expel objects from the inside of a 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 able to be 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, characterized in that:
a lining is hold removably with its upper hem near the edge of the opening of a bag;
an expandable sack is arranged on a base of the bag below the lining;
a compressed gas feeder located below the expandable sack includes
a small gas bottle having a pierceable mouth;
an elongated housing frontally connected to the small gas bottle and on its upper part to the expandable sack, internally carrying a piecing element having a bit provided with an axial passageway communicating with said expandable sack through its hollow cylindrical body which is endowed with rear ports and is axially movable under a pre-charged spring,
a release mechanism of the pre-charged spring to push the piercing element, having an ogival release member removably retained by means of at least a retaining flexible thin plate to a cylindrical body in abutment upon an end wall of the housing opposed to the small gas bottle which are at the same time housed in said ports of the hollow body and in a circumferential groove of said cylindrical body, so that, when the ogival release member is moved away from the contact with the small balls, the small balls disengage both the hollow body and the cylindrical body releasing the piercing element against the pierceable mouth of the small gas bottle;
control means of said release mechanism comprise a Bowden cable transmission, having in the one of its ends a connection to the release member and in the other one a junction member to a portion of a bag designed to be held permanently by who wears the bag,
so that a snatch, being transmitted to said portion of the bag through the Bowden cable transmission, operates the release mechanism and causes the expandable sack to be inflated until the lining is completely overturned.
Advantageously, said junction member is resoluble in the event of a bag-snatching so to separate the bag from the portion to be held permanently by who wears the bag.
