The invention claimed is: 1. A grip device integral with a movable object mounted on wheels, the grip device comprising: a supporting structure having two longitudinal members; a grip portion comprising a transverse member spanning the two longitudinal members and substantially parallel to an axis

The invention claimed is: 1. A grip device integral with a movable object mounted on wheels, the grip device comprising: a supporting structure having two longitudinal members; a grip portion comprising a transverse member spanning the two longitudinal members and substantially parallel to an axis of rotation of the wheels and a handle shaped body connected to the transverse member; and first and second articulating means permitting rotation of the handle shaped body about a first axis of rotation and a second axis of rotation, respectively, the first and second axes being perpendicular to each other, wherein the first articulating means permits rotation of the handle shaped body between a first work position and a second work position, the grip device further comprising biasing means for biasing the handle shaped body in at least the first work position. 2. The device of claim 1, wherein the biasing means comprises at least one friction washer. 3. The device of claim 1, wherein the first axis of rotation is parallel to the axis of rotation of the wheels, the first articulating means permitting rotation of the handle shaped body, with respect to the supporting structure, between a first work position wherein the handle shaped body projects from a free end of the supporting structure, and a second work position wherein the handle shaped body is turned 180° with respect to the first work position and collapsed inside the supporting structure. 4. The device of claim 3, further comprising locking means for preventing rotation of the handle shaped body with respect to the supporting structure and keeping the handle shaped body firmly and reversibly connected to the supporting structure when the handle shaped body is in the second work position. 5. The device of claim 4, wherein the locking means comprises connecting means for connecting the handle shaped body and the supporting structure. 6. The device of claim 5, wherein the handle shaped body and the transverse member abut each other along substantially mutually contacting surfaces, and are hinged to each other by a pin that extends perpendicular to the contacting surfaces. 7. The device of claim 6, wherein the handle shaped body comprises a cavity for insertion of a user's hand and first and second parallel hold portions located on opposite sides of the cavity and parallel to the transverse member, wherein the pin projects from the contacting surface of the transverse member and is housed entirely inside a seat formed in the first hold portion of the handle shaped body. 8. The device of claim 7, wherein the longitudinal members of the supporting structure are extensible telescopically, and comprise two parallel rods sliding inside respective guides and having respective end portions; the transverse member being located along the first axis of rotation to connect the end portions, and being connected in rotary manner to the end portions. 9. The device of claim 8, wherein the connecting means comprise flexible tabs carried by the end portions and having respective teeth which interface with respective retaining seats formed on the handle shaped body. 10. The device of claim 9, wherein the flexible tabs extend parallel to and a predetermined distance from the rods, respective lateral gaps of predetermined width being defined between the rods and the tabs, and wherein the handle shaped body has a width substantially equal to the distance between the tabs. 11. A movable object mounted on wheels having an integral grip device, the grip device comprising: a supporting structure having two longitudinal members; a grip portion comprising a transverse member spanning the two longitudinal members and substantially parallel to an axis of rotation of the wheels and a handle shaped body connected to the transverse member; and first and second articulating means permitting rotation of the handle shaped body about a first axis and a second axis of rotation, respectively, that are perpendicular to each other, wherein the first articulating means permits rotation of the handle shaped body between a first work position and a second work position, the grip device further comprising biasing means for biasing the handle shaped body in at least the first work position. 12.
