Suitcase and Set of Suitcases

Abstract

Suitcase comprising a main body, a base having three wheels suited for being into contact with the ground, where the contact areas of the wheels with the ground form a supporting polygon. The main body can pivot relative to the base between a static position and a dynamic position. Set of suitcases comprising a first and a second suitcase. The surfaces of the suitcases can be attached to each other and are equipped with openings. The openings can be placed opposite when the surfaces of the suitcases are attached against each other and comprise a closure system suited for isolating or giving access to the inner volume of the suitcases.

1 . A suitcase comprising a main body and also a base having at least three wheels, where the main body is mounted on the base so as to be able to pivot relative to the base between a static position and a dynamic position, where each of said at least three wheels is suited for being in contact with the ground (S), near a contact area both in the static position and in the dynamic position, and where the contact areas of said wheels with the ground form a supporting polygon in the static position and in the dynamic position. 
     
     
         2 . The suitcase according to  claim 1 , wherein the supporting polygon formed by the contact areas of the wheels with the ground have a width and a length, where said width is at least larger than one fifth of said length. 
     
     
         3 . The suitcase according to  claim 1 , wherein the main body comprises at least one lateral surface extending along an extension plane, where the main body is mounted on the base by means of a pivot located on said lateral surface so as to be able to pivot relative to the base around a direction perpendicular to said extension plane. 
     
     
         4 . The suitcase according to  claim 3 , wherein the main body furthermore comprises a second lateral surface opposite the first lateral surface, where the base comprises at least two supports each bearing at least one wheel where each of said supports is fixed to a respective lateral surface of the main body by means of a pivot located on said lateral surface; 
     
     
         5 . The suitcase according to  claim 4 , wherein the supports are mounted pivoting relative to the main body so as to be able to pivot independently of each other 
     
     
         6 . The suitcase according to  claim 4 , wherein the supports are connected to each other. 
     
     
         7 . The suitcase according to  claim 1 , furthermore comprising a locking mechanism suited for blocking pivoting of the main body relative to the base in at least one selected position chosen among the static position and the dynamic position. 
     
     
         8 . The suitcase according to  claim 7 , wherein the locking mechanism is suited for being able to be positioned in at least three operating states, including:
 a blocked state in which the locking mechanism blocks pivoting of the main body relative to the base;   an unlocked state in which the locking mechanism allows pivoting of the main body relative to the base; and   an armed state in which the locking mechanism blocks pivoting of the main body relative to the base following pivoting of the main body relative to the base.   
     
     
         9 . The suitcase according to  claim 7 , furthermore comprising a device for blocking the wheels suited for blocking at least one wheel of the suitcase, where the device for blocking the wheels is functionally connected to the locking mechanism so as to allow blocking of said at least one wheel when the locking mechanism is found in the unlocked operating state and when the locking mechanism is found in the armed operating state. 
     
     
         10 . The suitcase according to  claim 1 , furthermore comprising a telescoping handle.
