Definitions

• the present invention refers to the technical field of the containers in general, for example travel suitcase or backpacks of any form or size.
• the invention refers to a container which is structured in such a manner that results more long-lasting and it can be modified in its colors and/or decorations depending on necessities.
• trolleys suitcases are equipped with casters in order to simplify their transport and have restrained sizes. Their sizes are numerous and usually respect airport regulations. Some said suitcases have small sizes in order to be boarded as hand luggage, while in other cases they have bigger sizes.
• Suitcases can be divided into rigid ones or not rigid ones.
• Rigid suitcases are formed by an external shell which can be opened as a book and closed again and formed by rigid material which can be made of plastic or carbon-fibers or similar materials.
• the advantage of a rigid suitcase is that it can preserve better the contents in case of impacts or weights on it, since it maintains basically its original form even when it is squashed by the weight of other suitcases.
• suitcases are spreading commercially.
• Other types of suitcases may be made of normal textile but they distort themselves more frequently in case of overhead weights.
• a technical problem related to rigid suitcases is that they prove to be more fragile than textile suitcases, if they are submitted to strong impacts or weights. Obviously, during a travel, for example while squashing suitcases into the airplane fuselage, suitcases are often stuffed and thrown away with few care. The result is the risk of picking up a damaged, scratched or even broken suitcase upon arrival.
• the present container (1) for the transport of objects/ clothing/accessories/books comprising a frame (2, 10, 102) and at least a shell (2, 10), connected to the frame and delimiting at least partly an inner containment volume.
• such shell is connected to the frame in interchangeable way.
• the rigid container is thus formed by one or more shells made of rigid or semi-rigid material that form the body in its entirety.
• the shell forming such body (one or more than one) can be detached from the frame in such a manner that it can be possible to connect a new shell on it, obviously compatible to that kind of frame.
• two shells with different colors or shells with different design can be attached to the suitcase, thus making it creative according to the tastes or wishes of the moment.
• FIG. 1 shows schematically a suitcase to which a semi-shell 10 is applied in movable manner, once removed the original shell 2;
• FIG. 2 shows in lateral view a suitcase according to the invention
• FIG. 3 shows an exploded view drawing of the suitcase, according to the present invention
• Figure 4 and figure 5 show in axonometric view the suitcase in an opened configuration and in a closed configuration
• FIG. 12 is an axonometric view of the suitcase, showing the telescopic arm used to drag the suitcase;
• FIG. 16 and 16A show the telescopic arm applied to the frame of the suitcase
• FIG. 18 shows in an axonometric view the solution related to a shoulder backpack
• Figure 1 shows the axonometric view of a rigid suitcase according to the present invention.
• It can comprise an extractable/retractable handle, very well known in the background art in itself, by which the suitcase can be easily dragged.
• the suitcase can be easily equipped with wheels 3 in such a manner that it can be easily dragged by the user by the handle.
• the wheels 3 are in themselves very well known in background art and they are not a specific object of the present invention.
• the suitcase is provided with a frame to which can be applied external shells forming the body of the suitcase in its entirety (generally two shells) and such shells defining the containment volume of the suitcase itself.
• figure 1 shows generically the shell 2, which is movable and interchangeable with a new shell 10. The same applies obviously to the counterposed shell.
• Figure 2 shows a lateral view of the suitcase and underlines better a structure of the frame 11, wherein the left and right shells 2 are connected in interchangeable manner .
• Both shells can be removed and changed with other compatible shells if necessary, for example of different colors or materials and different shapes.
• the frame as per background art, is necessary for the overall support for fixing the wheels, the handles, the closing of the suitcase itself which can be opened into two halves and obviously it is necessary for supporting the fixing of the body, in this case a movable or whatever interchangeable fastening indeed.
• Number 30 and 30' show two common handles fixed on the two sides of the suitcase, in order to allow the user to lift the suitcase in two different ways.
• the handles are rotatable in respect with an anchoring body to which are fixed rotationally, for example the component 7 in figure 3.
• a shell 2 is shown detached from the frame to be clearer.
• Such shell, as well the counterposed one, is connected to the frame in such a manner that it can be detached from the frame and be reapplied, or can be changed with another equivalent one.
• the two traditional shells connecting to the frame of a traditional suitcase are now fully removable and replaceable by equivalent ones.
• the frame is formed by a sort of rectangular framework 11 which obviously traces the outside form of the luggage and to which the shell applies more or less as background art but it has the characteristic to allow the movable coupling with said shells.
• the frame is divided into two preferably symmetric coupling parts (11', 11").
• Each part of the frame forms such framework (11', 11') on which the shell is fixed.
• the framework forms a side guide in respect to which the edge of the shell is made moving from top to bottom.
• the shell has at its basis an appendix, for example a flap 2', in flexible material (for example it can be also the same material of the shell but with such a thickness that it results flexible and has a spring back) .
• an appendix for example a flap 2'
• flexible material for example it can be also the same material of the shell but with such a thickness that it results flexible and has a spring back
• Figure 7 and 8 show in axonometric view an inserting phase .
• the user can act on the flap manually by flexing it in order to cause the discharge of the pivot from the hole and thus proceeding with the removal of the shell.
• the component 6 represents a hinge which connects rotatably the two symmetrical halves of the frame each other (11', 11').
• the hinges are at the basis of the suitcase and not on its side, exactly at the basis where the wheels are placed and so the way of opening is that of figure 4 in which the couples of wheels are one towards the other in opened position.
• At least two hinges 6 placed side by side are provided.
• the component 9 shows the dragging handle which is connected to the extractable/retractable arm 4 (that is a telescopic arm) .
• extractable/retractable arms are usable as background art, as for example the arm shown in figure 1, such arm 4, contrary to background art is placed laterally and moves along a seat obtained along the side of the frame 11.
• Figure 12 shows the arm in the extracted configuration and moving slidingly in respect with a sort of track obtained by the external perimeter of the frame.
• the two halves of the frame (11', 11') form said sliding duct along their perimeter and said handle 9 disappears inside the area delimited by such two halves of the frame, as shown in figure 5, moving substantially to the same level of the body when fully retracted.
• Figure 16 shows well the compartment of the telescopic arm in respect with one half of the frame and in respect of which results sliding between extracted and retracted position.
• Figure 16A shows with number 40 the sliding track.
• the handle 9, as shown in the sequence of figure from 13 to 15, can be hinged to a point in such a manner that it can rotate depending on the needs in convenient positions for the user. It has preferably a L shape.
• Figure 17 shows an explaining example wherein, according to the invention, the external shell is substituted on said luggage with different models.
• figure 18 shows an exploded view drawing of a backpack according to the present invention.
• Such backpack comprises a frame 102, in the form of an annular element as well, which, like the suitcase, traces the outline form of the backpack.
• FIG. 18 shows with the number 101 the shell which inserts itself inside said annular frame, until the border of the shell contacts the annular frame in its whole lengths. Contrary to the solution of the suitcase, in this case the insertion occurs by pushing the shell against the frame and not by sliding, in such a manner that the mobile pivot 105, fixed to the frame, results insertable inside a receiving hole 106 of the shell.
• Figure 19 shows the pivot 105 when the shell has to be coupled with the annular element which forms the frame.
• Figure 20 shows the occurred coupling.
• the pivot is shaped in form of a triangle or arrow and then has a sloping side which allows its lateral translation while the shell is moving and so during the insertion of the pivot inside the hole, until, while fully inserted, the pivot springs another time moving to the opposite side and locking itself. In fact, it is provided a spring maintaining such pivot in the position of figure 19, that is fully translated on the right.
• the user has to move manually the pivot on the left in order to remove the shell, thus overcoming the force of the spring (or of the elastic element in general) .
• Figure 21 shows a solution with two symmetric pivots and two receiving holes.
• both the suitcase either the backpack or even other containers in general the shell or semi-shell is preferably made of rigid material, such as plastic, carbon-fibers, PVC, polypropylene, ABS, polycarbonate and similar ones and so it can be casted in a mould or shaped.
• such size of the shell delimits generally a more or less symmetric half of an overall containment volume (as for example the two shells of the suitcase or the shell of the backpack) .
• such shell might also be realized with semi-rigid materials, such as rubber. So it would result both very flexible either impacts absorbing.
• rigid or semi-rigid materials comprise moulding materials, for example in a mould to obtain the shape of the half suitcase (or the full luggage) that will cover the suitcase and so maintaining the shape of half luggage (or full luggage) and covering also without being applied to the suitcase.
• the textile is not to be considered a rigid or semi-rigid material.
• the invention is not only limited to the mere suitcase (meaning every type of suitcase including Trolleys), but also to bags, backpacks, pouches and so containers for personal use and transportable by the user.
