This invention relates to a piece of luggage as described in the preamble of the patent claims, particularly a suitcase designed as a travel suitcase.
Suitcases are known, for example, as hard shell suitcases having at least two suitcase shells which form a container and are connected by a hinge on one side, while they can be detachably connected to each other on another side by a closing device. The hard shells are especially made of vacuum-formed thermoplastic plates, respectively an acrylonitrile butadiene styrene (ABS) polymer. In order to make these heat-formed shell parts abrasion resistant, it is common to laminate an imprinted wrapping film made of a particularly abrasion resistant material to the ABS thermoplastic substrate. The substrate forms a base layer, while the wrapping film forms a cover layer with a higher abrasion resistance than the base layer. Furthermore, hard shell suitcases are known, in which the suitcase shell parts are made of a polycarbonate material. Such hard shell suitcases generally feature a monochrome exterior surface. In order to avoid traces of use on the exterior surface of the suitcase, according to the state of the art, the exterior surfaces, that is the respective cover layers of the suitcase shell parts, are made from a material which is as abrasion resistant as possible. Furthermore, suitcases made of aluminum are known.
Furthermore, a hard shell suitcase, especially made from aluminum or plastics, is known from German Utility Model Specification DE 20 2013 002 980 U1. This hard shell suitcase features three-dimensional protrusions that stand out from the outer surface and formed by at least two successive layers which are connected with each other. These layers may, for example, be imprinted. These layers may feature varying colors. The color design of a three-dimensional protrusion may be influenced by way of the colors. For example, shadows may be portrayed through the use of dark colors. As an example, the lowest layer may feature the darkest color. These layers are formed under an additional exterior layer which means that the imprinted rib-like protrusion is protected accordingly by the exterior layer. On the web page www.flyertalk.com/forum/travel-products/1430056-any-pics-user-rimowa-stealth-topas-bags.html, published on Jan. 21, 2013, it is described that scratches on the surface of a hard shell suitcase are especially easily visible, because a black coat of lacquer, in optical terms, particularly accentuates the scratches in the aluminum base layer.
Also, in order to avoid damage to the suitcase and unintended opening of the suitcase during transport, additional services for the protection of baggage are offered at airports. For instance, a service is offered to wrap the suitcase in film.
The suitcases known in the state of the art have not yet been optimally designed. The traces of use resulting from prolonged use of the suitcase are generally not desired by the user. This generally causes the user of the suitcase to exchange the suitcase for a newer model, even though the old suitcase is still functional, despite it showing respective traces of use. Furthermore, known suitcases have one disadvantage that the suitcases are individualized, for reasons of improved recognizability, with additional measures, such as luggage straps, or the application of adhesive labels or signs, or similar measures, so that the user of the suitcase can more easily recognize his or her suitcase, such as at the baggage transport conveyor belt.
One object of this invention is to design and further develop the initially mentioned piece of luggage to provide an easily customizable piece of luggage.
This object and others, which form the basis of this invention, are solved by having a piece of luggage with the characteristics as described in this specification and in the claims.
The piece of luggage features a base layer and at least one cover layer applied on top of the base layer. The cover layer is not transparent but opaque. The cover layer and the base layer feature varying colors at least in some areas. Especially the cover layer presents itself in a hue complementary to that of the base layer. The cover layer features a lower abrasion resistance than the base layer. Depending on their respective depth and width, the traces of use resulting from use reach layers of various colors, resulting in various hues becoming visible, which in turn results in the creation of individual color schemes on the exterior surface through abrasion of at least one cover layer. A piece of luggage is created with an exterior surface showing varying color schemes on the surface by the varying depths and widths of the traces of use, thus showing a customization. Through the abradability of the last cover layer or, respectively, cover layers and their varying colorations, scratches and other marks are more easily generated and are easily visible in order to emphasize the individuality of the piece of luggage for travel. The “history” of the piece of luggage for travel is easily visible in form of the traces of use.
The piece of luggage is preferably designed as a suitcase, especially a hard shell suitcase. The container is formed by at least one suitcase shell, where one exterior side of at least one suitcase shell forms the base layer, where at least one cover layer is applied on top of the base layer. During use, various layers are revealed through the various depths and widths of the abrasion traces, such as the traces of use, resulting in the creation of an individual coloration of the suitcase. The lower abrasion resistance of the cover layer, especially in comparison with the base layer, ensures the creation of additional traces of use on the exterior surface of the suitcase. The design resulting from the traces of use is always individual and easily recognizable, since subsequent layers of varying colors are formed on or attached to the exterior surface of the suitcase.
Several cover layers in varying colors are preferably provided. Each of the cover layers features a lower abrasion resistance than the base layer. All cover layers preferably feature varying colors, while none of the cover layers preferably feature the color of the base layer. Adjacent cover layers feature varying colors. The cover layer applied to the base layer features a different color than the base layer.
It is possible for the cover layers to be of layers of paint. It is possible for the base layer to be applied through a color layer, such as through powder coating. The cover layers could for example be applied through powder coating, painting, or similar means. It is possible for at least one of the cover layers to be formed from a textile material with a low abrasion resistance. It is possible for at least one of the cover layers to be formed from an easily tearable film. In an alternative design of this invention, at least one cover layer can be formed from an affixed layer of paper.
In an alternative design of this invention, the base layer can consist of or be of a textile layer. This textile layer features especially a higher abrasion resistance than the overlying textile cover layers. It is possible for the cover layer and the base layer to be applied through lamination.
The preferred design of the suitcase is that of an aluminum suitcase. In this case, the base layer can be tinted through anodizing of the aluminum shells. The overlying cover layer, respectively overlying cover layers are especially produced through an application of paint.
There are now a number of possibilities to further design and further develop the piece of luggage according to this invention. For this purpose, the dependent claims are referred to initially. The following describes a preferred design of the piece of luggage in accordance with this invention by the drawing and the associated description.
The suitcase 1b features a container 2. Container 2 limits the interior space, not shown in detail, of suitcase 1b. Container 2 is preferably formed by at least one hard shell 3, 4, especially by two hard shells 3, 4.
Suitcase shells 3, 4 are preferably made from a polycarbonate material. In an alternative design, it is possible for suitcase shells 3, 4 to be made from aluminum. Furthermore, designs are possible where the suitcase shells 3, 4 are vacuum formed from a thermoplastic material such as an ABS polymer.
Container 2 features several traces of use 7, 8. The traces of use 7, 8 in the area of the largest outer wall show that suitcase 1b features one base layer 9 and at least one cover layer 10, 11, preferably two cover layers 10, 11 as shown, on the exterior side of container 2. The cover layers 10, 11 are applied to the shaping wall of the container 2. The cover layers 10, 11 are applied to the exterior side of the wall. This base layer 9 and the cover layers 10, 11 are preferably especially formed on and applied to the two largest exterior surfaces of the piece of luggage 1a or the suitcase 1b. Furthermore, it is possible for the cover layers 10, 11 to be alternatively or additionally formed on the edges or corners of the suitcases 1b, as these edges and corners are more heavily worn during transport.
The base layer 9 and the cover layers 10, 11 each feature varying colors. At the same time, adjacent cover layers feature varying colors. The base layer 9 and the cover layers 10 and 11 form differently colored consecutive layers on the exterior surface of suitcase 1b. The cover layers 10, 11 are not transparent but opaque.
The cover layers 10, 11 consist of or include an abradable material. The traces of use 7, 8 generated during use reach differently colored layers depending on their depth and thickness, such as here, in the case of trace of use 8, cover layer 10 is subjacent to cover layer 11, and in the case of trace of use 7, cover layer 10 subjacent to cover layer 11, as well as base layer 9. These traces of use 7, 8 render the various layers of color visible, generating an individual color scheme on the exterior surface through abrasion of the upper cover layer 10, respectively the upper cover layers 10, 11. The traces of use 7, 8 are desired and serve to individualize the suitcase. The abradability of the upper cover layers 10, 11 and their different coloration more easily generate scratches, abrasions, and other traces of use 7, 8 in order to highlight the individuality of the piece of luggage (for travel) 1a, that is, suitcase 1b. The traces of use 7, 8 for example are inadvertently generated during transport of the piece of luggage 1a. It is however also possible for the user or owner of the piece of luggage 1a fashions said piece of luggage 1a himself or herself through artificial traces of use 7, 8. The user may, for example, treat the exterior side with its cover layers 10, 11 through scratching, scouring, or grinding in order to at least partially detach cover layers 10, 11 from the exterior side and thus to obtain an individual design.
The cover layers 10, 11 feature varying colors and consist of or include an abradable material, such as paint or a synthetic material. During use, the abrasion traces or traces of use 7, 8 with their varying depths and widths reveal a varying number of layers, resulting in an individual coloration of suitcase 1b.
The base layer 9 is formed by the form-giving, firm exterior wall of suitcase 1b. The base layer 9 is part of the suitcase shell 3 or 4. Two cover layers 10, 11 are applied to the base layer 9 that is one inner colored cover layer 10 and one outer cover layer 11. Both the inner cover layer 10 and the outer cover layer 11 are abradable. For example, the abrasion resistance or abrasion durability of the cover layers 10, 11 is lower than the abrasion durability of base layer 9.
The base layer 9 may contain several colors. It is possible for also the cover layers 10, 11 to contain several colors. Especially, the base layer 9 or the cover layers 10, 11 may contain several colors.
It is possible for the base layer 9 and/or the cover layers 10, 11 to feature motifs. However, the outer cover 11 is preferably monochrome, such as a single color. Especially the color layers underneath the outer cover layer 11, that is cover layer 10 or base layer 9 features motifs. In one design, exactly one cover layer 11 and one base layer 9 may be present, where the base layer 9 features motifs.
In the unused state of suitcase 1b, the motifs are preferably not visible since the outer cover layer 11 is not transparent, thus covering the motifs. The motifs become visible only through the traces of use 7, 8 that are generated during use.
It is possible for suitcase 1b to be sold with already existing traces of use 7, 8. The traces of use 7, 8 will be generated during production of suitcase 1b. The traces of use 7, 8 can be generated through scouring, grinding, or sandblasting.
In order to facilitate removal of the outer cover layer 11, at least one so-called motif template 12 is preferably arranged between the outer cover layer 11 and the base layer 9, or, as shown in
The motif templates 12 delineate the outline of the motif to be displayed. The motif template 12 preferably has a weaker bond with the adjacent layers than the layers among themselves. The bonds between cover layers 10, 11 and motif template 12 are especially weaker than the bond between cover layers 10, 11. There are now different possibilities of how the motif is generated by the traces of use 7, 8. In one design, it is possible for the cover layers 10, 11 and/or the base layer 9 to each be different monochrome colors, so that during use of suitcase 1b at least the outer cover layer 11 detaches in such places where the motif template is present. This way, the motif templates 12 become visible.
It is possible for the motif templates 12 to be bonded to the subjacent inner cover layer 10 in an easily detachable manner, so that the motif templates 12 also detach from the middle cover layer 10 as soon as the outer cover layer 11 is damaged in places where the motif templates 12 are present. This facilitates the detachment of the outer cover layer 11 in the shape of the motif. In this case, it is not compulsory for the subjacent cover layer 10 to feature the motif in the exact shape of the motif templates 12. Instead, the motif can be generated solely through detachment of the motif templates 12. In an alternative design, the inner cover layer 10 or the base layer 9 features a motif that is covered by the motif template 12. It is possible to also utilize corresponding motif templates 12 in designs in which exactly one outer cover layer 11 is stipulated. In this case, the motif template 12 is placed immediately between the outer cover layer 11 and the base layer 9. It is furthermore conceivable that several cover layers 10, 11 are present, and that the motif template 12 is not placed between the outer cover layer 11 and the subjacent cover layer 10, but between the base layer 9 and the first cover layer 10. The motifs may, for example, consist of or include various brands, logos, images, letterings, etc.
The disadvantages mentioned initially are thus avoided, while the relevant advantages are achieved.
