Utilitarian object collapsible on itself
The utilitarian object has a first part of a flexible material and a second part, adjoining the first, notably having at least one utilitarian accessory. The first part is an envelopment zone delimited by a casing in which is disposed a tie and capable of sliding on the tie between: a) a position of use in which the envelopment zone is appreciably flat, and b) a storage position in which the casing is gathered and the envelopment zone forms an envelope in which the second part is collapsed. The object is maintained in the storage position by locking the casing at the tie. It can be a backpack, the utilitarian accessory being at least one shoulder strap assembly and possibly a belt assembly. It can be a shopping bag, the second part having, as utilitarian accessories, two carrying handles.
1 . A utilitarian object comprising a first part of a flexible material and a second part, adjoining the first, notably having at least one utilitarian accessory, wherein the first part is an envelopment zone delimited by a casing in which casing is disposed a tie, said casing being capable of sliding on the tie between:
a) a first position, corresponding to the unfolded position of use of the object, in which the envelopment zone is appreciably flat, and
b) a second position, corresponding to the compressed storage position of the object, in which the casing is gathered and the envelopment zone forms an envelope in which the second part is collapsed in a compact state
and wherein the object is maintained in the compressed storage position by locking the casing at the tie.
2 . The utilitarian object according to claim 1 , said object having a means for locking the tie against said casing in its gathered position.
3 . The utilitarian object according to claim 1 , wherein the casing is a sheath added to the object, on the exterior or possibly on the interior, having at least one opening for passage of the tie.

5 . The utilitarian object according to claim 3 , wherein the sheath presents an open extremity, possibly reinforced with an eyelet, for the passage of a free extremity of the tie, the other extremity of the tie being attached to the other extremity of the casing adjacent to the free extremity of the tie exiting the casing.
6 . The utilitarian object according to claim 1 , wherein the casing has a discontinuous shape, for example, consisting of loops or clearance holes arranged along the edge of the envelopment zone.
7 . The utilitarian object according to claim 1 , wherein the configuration of the envelopment zone is circular.
8 . The utilitarian object according to claim 1 , wherein the envelopment zone presents an appearance different than that of the second part, notably being covered with a retro-reflective coating.
9 . The utilitarian object according to claim 1 , wherein the envelopment zone is formed of a different material than that of which the second part is formed.
10 . The utilitarian object according to claim 1 , having the shape of a backpack, the envelopment zone being disposed on the pack itself and the utilitarian accessory being at least one shoulder strap assembly and possibly a belt assembly.
11 . The utilitarian object according to claim 10 , wherein the shoulder strap assembly and possibly the belt assembly consist exclusively of straps and length-adjustment buckles.
12 . The utilitarian object according to claim 10 , wherein the envelopment zone is disposed centrally on the front surface of the pack.
13 . The utilitarian object according to claim 10 , wherein the pack itself holds about 15 liters and the envelopment zone has a surface of about 350 cm 2 .
14 . The utilitarian object according to claim 1 , wherein the object has the shape of a shopping bag, the second part having, as utilitarian accessories, two carrying handles.
15 . The utilitarian object according to claim 14 , wherein the envelopment zone constitutes, in whole or in part, the bottom of the bag and is possibly formed of a different material than that of the second part of the bag, an exception possibly being made for the carrying handles.
16 . The utilitarian object according to claim 1 , wherein the object has the shape of a garment, notably a poncho type, the second part having as utilitarian accessory a hole for passage of the head and a hood.
