Abstract
A piece of luggage is disclosed which consists of a case in the shape of a flat parallelepiped comprising two greater rigid lateral walls and a rigid quadrangular frame with an upper side provided with a curved handle, a base side and end sides. At least one of its lateral walls is movable, being provided with a rigid perimetral edge which slides telescopically within the frame. Displacement of this lateral wall occurs in a direction perpendicular to its plane between a retracted position in which it is located in the plane of the corresponding edge of the frame and a projecting position. The result is that the internal volume of the case is increased.

A parallelepiped luggage case, comprising:
- a rigid quadrangular frame having an upper side with means for carrying said case, end sides and a base side;
- first and second lateral walls lying in opposed parallel planes, at least one of said first and second lateral walls having a single walled frame perpendicular thereto along its perimetral edge, said single walled frame being telescopically slidable with respect to said quadrangular frame to allow the displacement of said lateral wall in a direction perpendicular to its plane between a retracted position in which it is located adjacent the quadrangular frame and a projecting position in which it is located spaced away from the quadrangular frame, for increasing the internal volume of said case;
- a spring means being compressed between the lateral wall and the quadrangular frame for engaging said lateral wall and urging it towards the projected position with respect to the frame;
- means formed in the quadrangular frame for guiding said single walled frame between extreme positions;
- and
- means coupled to the single walled frame for retaining the lateral wall in the retracted position against the compression of the spring means including a cursor having at least one latch, said cursor being slidable between first and second positions in a plane parallel with the base side and a coil spring engaging the cursor for urging it to the first position.

A parallelepiped luggage case, comprising:
- a rigid quadrangular frame having an upper side with means for carrying said case attached to the upper side, end sides and a base side;
- first and second lateral walls lying in opposed parallel planes, at least one of said first and second lateral walls having a single walled frame attached thereto along its perimetral edge, said first lateral wall being divided into two panels hingedly connected to the corresponding edges of the two end sides of said quadrangular frame, means for opening said panels in the same way as the doors of a cupboard;
- said single walled frame being telescopically slidable with respect to said quadrangular frame to allow the displacement of said lateral wall attached thereto in a direction perpendicular to its plane, between a retracted position in which it is located adjacent the quadrangular frame and a projecting position spaced from the quadrangular frame, as a result of which the internal volume is increased;
- and
- a partition formed by first and second bars, said first bar has a height corresponding to the spacing between said first and second lateral walls when said second lateral wall is retracted, said partition being hinged to said second lateral wall and provided with guide means extending vertically, said second bar being slidable in the guide means between a lowered position in the space of the hinged bar and a raised position in which it occupies the space between the hinged bar and the first lateral wall, when the second lateral wall is located in the projected position.

A parallelepiped luggage case, comprising:
- a rigid quadrangular frame having an upper side with means for carrying said case, end sides and a base side and further comprising first and second half-frames hingedly connected along a medium plane of said frame and wherein each of said first and second half-frames is formed of an inner wall and an outer wall defining a slot therebetween;
- first and second lateral walls lying in opposed planes parallel to the medium plane, at least one of said first and second lateral walls having a single walled frame perpendicular thereto along its perimetral edge, said single walled frame being telescopically slidable with respect to said quadrangular frame to allow the displacement of said lateral wall in a direction perpendicular to its plane between a retracted position in which it is located adjacent the quadrangular frame and a projecting position in which it is located spaced away from the quadrangular frame, for increasing the internal volume of said case,
- a spring means being compressed between the lateral wall and the quadrangular frame for engaging said lateral wall and urging it towards the projected position with respect to the frame;
- means formed in the quadrangular frame for guiding said single walled frame between extreme positions;
- and
- means coupled to the single walled frame for retaining the lateral wall in the retracted position against the compression of the spring means.
