• the metal rods are provided in the form of two rectangular-shaped side frames with rounded corners encircling the fabric side faces.
• the side faces encircled by a perimeter of steel ring are flexible and can adapt with more play to receive the side faces of smaller suitcases.
• a first object of the invention is to propose a novel method of manufacturing flexible luggage using a reduced number of components.
• a second object of the invention is to provide a new flexible luggage in which the outer fabric or envelope is stretched on the inner structure of the luggage, so as to avoid the occurrence of unsightly folds or gathers.
• the subject of the invention is a method for manufacturing flexible luggage, comprising the following steps: a) equipping a C-shaped elastic plate with upper and lower reinforcements, b) inserting the C-shaped elastic plate and reinforcing it inside. a flexible envelope, to stretch the envelope so as to avoid the formation of unsightly folds and gathers, c) to mount lower corner reinforcements with the interposition of spacer rods.
• the method may comprise a step of mounting telescopic handle elements.
• the method may comprise a step of mounting a floor reinforcement, especially honeycomb.
• the method may comprise a step of mounting reinforcements on both sides of the flexible envelope, so as to take the flexible envelope sandwich avoiding the formation of folds or unsightly puckering.
• the upper reinforcements are advantageously constituted by front and rear corners braced by a rod.
• the invention also relates to a flexible bag comprising a resilient plate shaped in C and reinforced by upper and lower reinforcements, said elastic plate C-shaped being inserted inside a flexible envelope to stretch the envelope so to avoid the formation of unsightly folds and gathers, said flexible luggage further comprising lower corner reinforcements with the interposition of spacer rods.
• the flexible luggage may comprise telescopic handle elements.
• the flexible luggage may comprise a floor reinforcement plate, in particular made of honeycomb.
• the flexible baggage may comprise reinforcements mounted on either side of the flexible envelope so as to take the envelope sandwich, avoiding the formation of folds or unsightly puckering.
• the flexible baggage may comprise upper reinforcements consisting of front and rear corners braced by a rod.

• FIG. 7 schematically represents a sixth step of a process for manufacturing flexible luggage according to the invention.
• a set of structural components of flexible luggage comprises a polypropylene elastic sheet 1, 4 rods 2a, 2b, 2c, 2d, fiberglass, two upper reinforcement assemblies 3a, 3b, and 4 lower corner assemblies 5,6, 7 and 8.
• a reinforcement sheet 9 honeycomb may be provided for the floor of the luggage.
• a telescopic handle assembly comprising elements 10 to 13 may also be advantageously provided in the case of a wheeled luggage.
• the polypropylene plate 1 is preferably elastic and shaped in C, so as to form an upper rim and a lower rim.
• the vicinity of the upper flange has an opening for the passage of the telescopic handle assembly, while the lower flange has two lateral notches for mounting lower corners, also constituting wheel housings in the case of luggage. on wheels.
• the reinforcement assemblies 3 a, 3 b are advantageously formed as double wedges connected by a short fiberglass rod.
• the floor of the polypropylene sheet is equipped with the honeycomb reinforcement plate 9, which is fixed in place by two rivets R.
• the rivets R also advantageously fix the housing 10 intended to receive the lower end of the telescopic tube 13.
• honeycomb reinforcing plate 9 is positioned and sandwiched between the support
• the reinforcing structures 3 a, 3 b consolidate the angles of the upper flange of the polypropylene plate 1 and ensure the maintenance of the C-shaped conformation.
• each set 3a or 3b is constituted by two corner pieces fixed by rivets to the plate 1 made of polypropylene and braced by short stems fiberglass.
• This arrangement allows the adjustment of the two corner pieces with respect to the upper edge, and compensates for the geometric variations of the conformation in C.
• the outer casing 14 is mounted on the structure described with reference to FIG. 2.
• the outer casing 14, which also comprises a through hole intended for the passage of the telescopic handle assembly, is mounted under tension on the structure, so as to avoid the formation of folds or unsightly puckering.
• the lower end of the telescopic tube 13 is fixed by two screws V to the lower support 10, while the elements 11 and 12 can simply remain positioned on either side of the openings made in the polypropylene elastic plate 1 and in the envelope 14 in flexible textile.
• the fiberglass rods 2a, 2b are positioned and fixed to the rear upper corners of the assemblies 3a and 3b. Ideally, the rods are then positioned in the wheel housings 5 and 6.
• the wheel housings 5 and 6 are then attached to the lower rear corners of the polypropylene elastic sheet 1, to simultaneously maintain the back side of the luggage and the mounting of the wheels carried by the housings 5 and 6.
• the fiberglass rods 2c and 2d are mounted on the upper front corners of the structures 3a and 3b, being aligned and fixed at the corresponding angle of the envelope 14.
• the upper ends of the fiberglass rods 2c, 2d are permanently inserted into the upper corners of the structures 3a, 3b, so as to avoid lateral crushing or buckling of the fiberglass rods 2c, 2d.

• the front legs 7 and 8 are mounted at the lower ends of the fiberglass rods 2c, 2d by sandwiching the front portion of the casing 14.
• the wedge-shaped pieces 7 and 8 are constituted by a combination of two geometric prisms ensuring the jamming of the lower ends of the fiberglass rods 2c, 2d. After ensuring the assembly of the structure of the flexible bag, it remains to fix the casings 11 and 12 between them by sandwiching the corresponding portion of the flexible envelope 14 textile.
• the assembly order of the flexible baggage obtained by the method according to the invention thus makes it possible to obtain a suitcase or luggage with flexible wheels without any folds or unsightly puckering.
• the lateral reinforcement provided by the fiberglass rods 2a, 2b, 2c, 2d prevents any sagging of the C-shape of the polypropylene plate 1, while the reinforcement of the floor provided by the plate 9 in the nest bee prevents any deformation of the floor, even in case of heavy load.
