Abstract

The wheeled suitcase comprises:a rigid or semi-rigid suitcase body (1), mounted on wheels (30), said body (1) comprising at least three rigid or semi-rigid lateral faces (5, 9) separated by two edges (13), anda telescopic twin rod (16) comprising two arms (17), a handle and two tubes, the arms (17) being connected to the handle (18) and slidingly mounted in both tubes (21),said suitcase being characterized in that the two tubes (21) are disposed along the two edges (13) outside the body (1) of said suitcase.

First claim

The invention claimed is:

1. A wheeled suitcase comprising:
a rigid or semi-rigid suitcase body, mounted on wheels, said body comprising at least three rigid or semi-rigid lateral faces separated by two edges, and
a telescopic twin rod comprising two arms, a handle and two tubes, the arms being connected to the handle and slidingly mounted in both tubes,
wherein the two tubes are disposed along the two edges outside the body of said suitcase,
each of the two edges is recessed, presenting a concavity facing the outside of the suitcase body,
the tubes are received in the recessed edges, and
each of the tubes presents a profile with a cross section defined by an outer portion and an inner portion, the outer portion defining an arch presenting two ends, wherein the outer portion extends in the vicinity of the two ends tangentially to two contiguous lateral faces to the edge in which the tube is received, the inner portion being configured to substantially follow the concavity of said recessed edge in which the tube is received.

2. The wheeled suitcase according to claim 1 , wherein the tubes are attached to the two edges by rivets or screws.

3. The wheeled suitcase according to claim 1 , wherein the tubes present open ends by which the arms are introduced, and
wherein a rigid intermediate part is positioned between the tubes and extends from the open end of one tube to the open end of the other tube.

4. The wheeled suitcase according to claim 3 , wherein one of the lateral faces is a back face of the suitcase body, and
wherein said suitcase body comprises a top face separated from the back face by an upper edge of the suitcase body,
said upper edge being recessed, presenting a concavity facing the outside of suitcase body,
the rigid intermediate part having a shape complementary to the concavity of the upper edge and
the intermediate part being fixed in said upper edge.

5. The wheeled suitcase according to claim 4 , wherein the handle is movable between a retracted position and an extended position and comprises, over at least one portion of its length, a cross section defined by the outer handle portion and an inner handle portion,
the outer handle portion defining an arch presenting two ends,
the two ends being found in the extension of the planes defined by, respectively, a lateral face of suitcase body and the top face of suitcase body.

6. The wheeled suitcase according to claim 5 , comprising a free space between the handle and the rigid intermediate part in the retracted position of the handle.

7. The wheeled suitcase according to claim 1 , also comprising at least two wheeled devices which are rotatable around two respective pivot axes, said wheeled devices being mounted on a bottom face of the suitcase body.

8. The wheeled suitcase according to claim 7 , wherein the tubes present a tube end situated in the vicinity of a wheeled device, said tube end presenting an edge defining an inner space of the tube, and wherein the pivot axis of the wheeled device extends in said inner space of the tube.

9. The wheeled suitcase according to claim 7 , wherein each wheeled device is attached in the vicinity of a tube with which it is associated, and
each of the two pivot axes is parallel to a main axis of the tube with which said wheeled device is associated,
a pivot axis of a wheeled device being spaced apart from an associated main tube axis by a distance of less than 20 millimeters, preferably zero millimeters.

10. The wheeled suitcase according to claim 7 , wherein each of the wheeled devices is fixed to an element mounted on a tube.

11. The wheeled suitcase according to claim 7 , wherein each wheeled device is attached in the vicinity of a tube with which it is associated, and
each of the two pivot axes is parallel to a main axis of the tube with which said wheeled device is associated,
a pivot axis of a wheeled device being spaced apart from an associated main tube axis by a distance of zero millimeters.

12. The suitcase according to claim 1 , comprising damping elements.

13. The suitcase according to claim 12 , wherein the damping elements are parts mounted on a lateral face of said body of said suitcase, in the vicinity of the tubes.

14. The suitcase according to claim 12 , wherein the tubes comprise said damping elements.
