The expander includes side walls positionable against a bag interior, members articularly connected together and to the side walls, and an arcuate enabling diamond shaped mechanism connected between the members and the side walls to provide a selected expanding and contracting amongst the members and the side walls. The members are in a folded condition when the bag is compressed and, with the aid of an expansion motivator such as a rubber band, spring and the like, the bag is expanded to its deployed condition.

1. For use with a bag having an interior, a bag expander for enabling its insertion into the bag interior when the bag is in a compressed condition and for enabling its expansion of the bag when the bag is to be positioned into an expanded deployed condition, comprising: side walls positionable against the bag interior;members connected together and coupled to said side walls to form articulate connections therebetween;joints associated with said members and said side walls providing said articulate connections thereamongst thereby enabling the insertion and expansion; andan expansion motivator associated with said members enabling expansion thereof from the bag compressed condition to its expanded condition, wherein said side walls are thus enabled to remain in contact with the bag interior, said members having a folded condition when the bag is in its compressed condition and having an expanded condition when the bag is in its expanded deployed condition,wherein said joints include axle pins which respectively join said members and which said joints are spaced from one another, said axle pins having connecting points, and in which said expansion motivator comprises spring devices coupled to opposed ones of said axle pin connecting points. 2. The bag expander according to claim 1 in which (a) said members, as articulated together, terminate in alternately-directed generally C-shaped closures, (b) each said axle pin comprises a pair of parallely extending legs joined together by a plurality of spaced connecting pieces forming connecting points to which said C-shaped closures are pivotally connected, and (c) said axle pin connecting points are formed at the ends of each of said parallely extending legs for receiving said spring devices and for being biased thereby. 3. The bag expander according to claim 2 wherein said members comprise a plastic material. 4. The bag expander according to claim 1 wherein at least some of said members are coupled together to form a plurality of diamond-shaped configuration parallely placed between said members. 5. The bag expander according to claim 1 wherein said expansion motivator comprises at least one spring member. 6. The bag expander according to claim 5 wherein said spring member comprises coil springs. 7. The bag expander according to claim 5 wherein said spring members comprise rubber bands. 8. The bag expander according to claim 1 wherein said expansion motivator comprises flat springs. 9. For use with a bag having an interior, a bag expander for enabling its insertion into the bag interior when the bag is in a compressed condition and for enabling its expansion of the bag when the bag is to be positioned into an expanded deployed condition, comprising: side walls positionable against the bag interior;members connected together and coupled to said side walls to form articulate connections therebetween;joints associated with said members and said side walls providing said articulate connections thereamongst thereby enabling the insertion and expansion; andan expansion motivator associated with said members enabling expansion thereof from the bag compressed condition to its expanded condition, wherein said side walls are thus enabled to remain in contact with the bag interior, said members having a folded condition when the bag is in its compressed condition and having an expanded condition when the bag is in its expanded deployed condition,in which (a) said articulate connections include axle pins, (b) said members, as articulated together by said articulate connections, terminate in alternately-directed generally C-shaped closures, (c) each said axle pin comprises a pair of parallely extending legs joined together by a plurality of spaced connecting pieces forming connecting points to which said C-shaped closures are pivotally connected, and (d) axle pin connecting points are formed at the ends of each of said parallely parallely extending legs for receiving said spring devices and for being biased thereby. 10. The bag expander according to claim 9 wherein at least some of said members are coupled together to form a diamond-shaped configuration. 11. The bag expander according to claim 10 further including at least second ones of said members formed into a second diamond-shaped configuration which is articulately joined to said at least one of said members and in which said second diamond-shaped configuration (a) is also articulately joined to said side walls in parallel with said first-mentioned diamond-shaped configuration, (b) is similarly constructed as said first-mentioned diamond-shaped configuration and (c) biased by said spring devices. 12. The bag expander according to claim 10 further including at least a second of said members coupled together to form at least one additional diamond-shaped configuration which is serially coupled to said first-mentioned diamond-shaped configuration. 13. For use with a bag having an interior, a bag expander for enabling its insertion into the bag interior when the bag is in a compressed condition and for enabling its expansion of the bag when the bag is to be positioned into an expanded deployed condition, comprising: side walls positionable against the bag interior;members connected together and coupled to said side walls to form articulate connections therebetween;joints associated with said members and said side walls providing said articulate connections thereamongst thereby enabling the insertion and expansion; andan expansion motivator associated with said members enabling expansion thereof from the bag compressed condition to its expanded condition, wherein said side walls are thus enabled to remain in contact with the bag interior, said members having a folded condition when the bag is in its compressed condition and having an expanded condition when the bag is in its expanded deployed condition,wherein: said expansion motivator comprises at least one spring member and said spring member comprises coil springs, andsaid members comprise substantially inflexible material; andsaid joints providing said articulate connections comprise axle pins positioned (a) between mating ones of said members and (b) between mating others of said members and said side walls, andfittings terminating said members and pivotally engaging said axle pins; andsaid coil springs have centers and ends such that said spring centers are positioned about said axle pins which are positioned between mating ones of said members, andsaid spring ends are positioned against said mating ones of said members. 14. The bag expander according to claim 13 wherein said axle pins respectively join said members together and to said side walls and which are spaced from one another, said axle pins having connecting points, and in which said expansion motivator comprises spring devices coupled to opposed ones of said axle pin connecting points. 15.
