- adhesive material 3 may be located along the entire length of the base of seat 7a and/or over the entire surface of seat 7a which comes into contact with outer surface 4a of shell 1a. Pre-treatment of the surface parts of fins 8a which will come into contact with the inner surface 5a of shell 1a is also a possibility.
- This pre-treatment comprises suitable activation, for example by plasma activation, preferably using cold plasma, of the part of the interface surface which is to be activated in such a way as to form an activated layer 9 thereupon, the depth of which is particularly shallow, at least such as not to diminish the mechanical properties of the underlying material.

- This activated layer 9 has the property of being very much more adherent to adhesive material 3 than the material used for the elements which are to be bonded would otherwise be.
- This treatment therefore makes it possible to use polymer materials such as those indicated above when manufacturing bonded suitcases, for which adhesive bonding was hitherto unthinkable, thus achieving an appreciable saving in weight.
- structured suitcases can even be obtained with thin and therefore very light shells whose resistance to squashing and impacts is mainly due to the frames which can be manufactured with the necessary robustness without having an overall disadvantage on the weight of the suitcase.
- Frames 2a and 2b may be used to support means for rotatably joining two parts of the suitcase together as indicated diagrammatically by 10 in Figure 1.

Abstract
Description
- This invention relates to a lightweight structured suitcase, that is a suitcase according to the precharacterising clause of
claim 1 and a method for its manufacture in accordance with the precharacterising clause of claim 8. - Suitcases of the known type are substantially subdivided into two major types: soft and rigid suitcases.
- The context which requires the maximum performance from suitcases is that of air transport. Suitcases must in fact be at the same time lightweight, so as not to excessively reduce the maximum quantity of baggage which can be carried by a passenger, and strong, in order to adequately protect their load from the impacts which they inevitably incur during handling within airport equipment for the automatic distribution of baggage.
- Soft suitcases, generally made of synthetic material or fabric, are lightweight and flexible but are easily torn and are unable to effectively protect the objects within them against impacts.
- Rigid suitcases are generally provided with shells of rigid metal or polymer material and locks; these are the only ones capable of combining a high level of protection for the objects within them and high resistance to tearing.
- Despite the fact that they are heavier and more bulky than other suitcases, they are preferred by those travelling by air, specifically because of their greater security.
- The weight limits imposed on passengers by airlines are not however easily reconciled with the weight of rigid suitcases. It is therefore particularly important that the structure of the suitcase should be lightened in order to increase the weight available for the baggage which has to be carried.
- Rigid suitcases are generally formed of two shells with corresponding integral stiffening mouldings about their perimeter which ensure the mechanical and structural properties necessary for normal use of the suitcase.
- The connection between the various components of a suitcase, such as for example between the shells and the stiffening mouldings, is currently brought about for example through riveting, sewing or stapling.
- Among the alternative methods to those mentioned above, adhesive bonding would appear to be particularly advantageous from the point of view of both weight and ease and speed of execution were it not for the difficulties encountered in carrying out bonding operations between plastics materials.
- In view of the state of the art described, the object of this invention is to provide a suitcase which makes it possible for two components, such as for example a shell of polymer material and the corresponding moulding, to be joined together through adhesive bonding resulting in suitcase structures which are particularly light and at the same time very strong.
- In accordance with this invention this object is achieved through a suitcase according to
claim 1 and through a method according toclaim 10. - The features and advantages of this invention will be obvious from the following detailed description of a practical embodiment provided by way of a non-restrictive example with reference to the appended drawings, in which:
- Figure 1 shows a suitcase in a semi-open configuration constructed in accordance with an embodiment of this invention,
- Figure 2 shows a partly exploded detail of a suitcase according to Figure 1,
- Figure 3 shows a disassembled detail in perspective cross-section of the shell/moulding assemblies of a suitcase illustrated in Figures 1 and 2,
- Figure 4 is a partly disassembled view of the detail in Figure 3 in the direction indicated by arrow A.
- The suitcase illustrated in Figure 1 comprises two
elements adhesive material 3 which is capable of joining them firmly together through adhesive bonding. - Advantageously these two
elements shell 1a, preferably of polymer material, and astiffening frame 2a, but obviously they may be any two components of the suitcase which must be firmly joined together. - For example, the adhesive bonding of any accessory or equipment such as for example a handle, a lock, a hinge or the frames therefor to the frame of the suitcase may be considered.
- In a preferred embodiment at least one of the two
elements adhesive material 3 is placed to bond them together is made of preferably thermoplastic polymer material; suitable materials may for example be PC, PC/ABS, ABS, PP, HDPE. - Each of the two
shells external surface inner surface perimetral surface 6a, 6b. - At least one of
shells - Figure 3 also shows a cross-section of
stiffening frames seat shell -
Seats shells - Preferably these
fins - First and
second elements adhesive material 3 when the suitcase is assembled. -
Adhesive material 3, which is advantageously silicone based, is then placed in contact with at least one part of the two interface surfaces, advantageously on a part such that it is located over the entire interface surface when the suitcase is assembled. - In the case where the two
elements shell 1a andstiffening frame 2a,adhesive material 3 may be located withinseat 7a close to the base ofseat 7a. Advantageouslyadhesive material 3 may be located along the entire length of the base ofseat 7a and/or over the entire surface ofseat 7a which comes into contact withouter surface 4a ofshell 1a. Pre-treatment of the surface parts offins 8a which will come into contact with theinner surface 5a ofshell 1a is also a possibility. - In order to obtain a better bond with adhesive 3 it is possible to pretreat at least part of the interface surfaces or, advantageously, the entire extent of one or both interface surfaces; for example, in the case in which
shell 1a is bonded to stiffeningframe 2a the entire bottom surface ofseat 7a and at least that part of its sides which will be in contact withadhesive material 3 may be treated; with regard to the shell, peripheral surface 6a and/or that part ofouter surfaces 4a and/orinner surfaces 5a which will be in contact withadhesive material 3 may be treated. - This pre-treatment comprises suitable activation, for example by plasma activation, preferably using cold plasma, of the part of the interface surface which is to be activated in such a way as to form an activated
layer 9 thereupon, the depth of which is particularly shallow, at least such as not to diminish the mechanical properties of the underlying material. - This activated
layer 9 has the property of being very much more adherent toadhesive material 3 than the material used for the elements which are to be bonded would otherwise be. - This treatment therefore makes it possible to use polymer materials such as those indicated above when manufacturing bonded suitcases, for which adhesive bonding was hitherto unthinkable, thus achieving an appreciable saving in weight.
- In fact in accordance with the invention structured suitcases can even be obtained with thin and therefore very light shells whose resistance to squashing and impacts is mainly due to the frames which can be manufactured with the necessary robustness without having an overall disadvantage on the weight of the suitcase.
-
Frames - Obviously in order to satisfy contingent and specific requirements a person skilled in the art could apply many modifications and variants to the configurations described above, all of which are however included within the scope of protection of the invention as defined by the following claims.
