Background Art [2] The conventional equipages do not have in its interior devices incorporated for compensatory internal fulfilling. The adequate accommodation and protection of the objects to be carried depend on the choice of an equipage with available volume very near to the objects and the ability of the user in organizing these objects. Another way would be to involve the objects before its placement, or the fulfilling with squeezed paper, or any another soft item that will be throw away after the transport of the object, to fill the empty spaces. Although, even if the user obtains good placement and protection of the objects in the beginning of trip, he will have problems when he removes the most voluminous or includes acquisitions effected during the trip.

There are others non-dismissible ways that, despite of also being inflatable, are not fixed in the equipage and are just common inflatable packings to be placed inside of containers, having these packings to be the same size of the container since they have a fixed size; or also of inflatable cushions to be placed inside of other containers involving the object and occupying the empty space, having these to possess a size that is in agreement with the object to be carried as much as the container. These non- dismissible ways still possess one another problem, because they are air cushions that possess a certain volume even when they are empty, and in the case of the fulfilling of the container in elapsing of the transport or trip they must be carry separated, becoming it to the user a problem and not a solution.

Disclosure The present innovation, meanwhile, consists of the insertion in the interior of the equipage a pneumatic bag, inflatable by the external part, capable to offer a better ar- rangement of objects in its interior, without being necessary carry the bag separately or carry it separated in the case of the increase of the number of objects, or a reduction of space in elapsing of the trip, or still, and mainly, being unnecessary the previous knowledge of dimensions of the object for this storage and transport.

[5] This invention allows the user, for example, in trips, to make use of space for ar- rangement of the purchases made. The equipage in itself presents fixed volume, however, is endowed with a bag capable to compensate the variations of the internal volume without adding weight and, still, keeping the stability of the luggage.

[6] Finally, the present innovation increases the versatility, practicability, and protection of carried objects, providing more comfort and bigger security as the usual luggages.

Description Of Drawings [7] The matter becomes perfectly understood in the following description, with references to the indicative numbers listed on the attached drawings, highlighting its main characteristics.

Mode for Invention [11] In according with the related drawings, the volumetric compensator (1) for equipages (2) consubstantiated in the insertion of a pneumatic bag (3) settled inside (4) of the equipage (2) resulting in one better arrangement of the objects (5).

[12] The volumetric compensator (1) is composed by a pneumatic bag (3) settled inside of (4) the cover (6) of the equipage (2) that will be inflated by means of a located piston (7) in the extremity of this pneumatic stock bag (3). The piston (7) can be uttered to the proper equipage (2) by means of its longitudinal displacement for the exterior part of the cover (6), making with that the inflation of the pneumatic bag (3) take effect through the air insertion inside of the pneumatic bag (3) being this air insertion done from the outside, by the proper human effort without the necessity of no special equipment, despite the possibility of mechanically pumping and, later, is remained inflated by the maintenance of air inside of it, through the closing of the piston (7) by a check valve (8).

[13] After the arrangement of objects (5) inside of the equipage (2), the user will have to dislocate the piston (7) longitudinally for outside of the cover (6) of the equipage (2) so that it can, by means of air insertion to set in motion the inflation of the pneumatic bag (3) and this, consequently, can occupy all and any still not busy space. Finished the inflation, the piston (7) must be shut with the check valve (8) and later dislocate it, again, for inside of the cover (6) of the equipage (2). When initiating the inflation process, the pneumatic bag (3) will adapt itself to the content found in the equipage (2), or either, always that happen an unevenness among the objects (5) found in the equipage (2) the pneumatic bag (3) will be responsible of occupying this space produced by the unevenness, thus the objects (5) can Bud stability in the interior (4) of the equipage (2).

[14] The advantages of this volumetric compensator (1) meet in its easiness and practiceness, since in order to have a deactivation of this compensator (1) it is necessary, solely, that the check valve (8) responsible for keeping inflated the pneumatic bag (3) be opened and make possible the exit of air, coming back that one (3) to an initial state, in way not to occupy any space and not even attributes weight to the traditional equipage (1).
