Protective device of a mobile electronic device

Background of the invention

The invention relates to a protective device of an electronic mobile device, such as a laptop, with a stretch-resistant, first layer which has a first side facing the mobile device and a second side facing away from the mobile device, an adhesive layer being formed flat against the first side.

For the protection of electronic mobile devices, especially portable ones

Computers in the form of laptops, a so-called "skin" in the form of a skin or adhesive film is known, which can be cut to the outer contour of the laptop and glued to its top or bottom. The film is formed with a stretch-resistant layer made of plastic, which has a first side facing the mobile device and a second side facing away from the mobile device, directed outwards and usually printed. An adhesive layer is then formed on the first side of this layer, referred to here as the first, stretch-resistant layer. By means of the adhesive, the film can be glued to the top or bottom of the mobile device in particular in such a way that the adhesive film protrudes to its edge or outer contour.

Such known skins have the disadvantage that they only protect the associated mobile device comparatively little against impact and scratch damage.

Covers, so-called cases, are therefore also known, which form a type of cover or suitcase around the mobile device. Such a case is usually formed with an upper part or an upper shell and a lower part or a lower shell, each on and around the top or bottom of the mobile device is clipped around on this. The case is detachably mounted on the mobile device and also protects its edges and outer contour.

However, known cases have the disadvantage that they are often not visually appealing and therefore do not allow the associated mobile device to come into its own.

Underlying task

The invention is based on the object of creating a protective device for an electronic mobile device with which the above-mentioned disadvantages are overcome and, in particular, an advantageous protection of the associated mobile device with an appealing visual appearance is created.

Solution according to the invention

According to the invention, this object is achieved with a protective device

Electronic mobile device, such as a laptop, detached, with a stretch-resistant, first layer which has a first side facing the mobile device and a second side facing away from the mobile device, an adhesive layer being formed on the first side and lying flat on the second side a second layer is formed in a flat manner.

According to the invention, a stretch-resistant, first layer is understood to mean a layer which can be loaded in the direction of its layer plane or surface plane by means of manual force without being permanently stretched and deformed. The yield strength of the material or material of this layer describes the ability to withstand mechanical loads before failure occurs, and is specified as mechanical stress (force per cross-sectional area, N / mm ² ). The failure would be an impermissible deformation, in particular a plastic (permanent) deformation or a Fracture. The yield strength depends in particular on the material and how it is processed. Materials with high yield strength can be subjected to higher tensile stresses than materials with low yield strength. The yield strength is a material parameter and

refers to the stress up to which a material does not show any permanent plastic deformation under uniaxial and moment-free tensile stress. If the yield point is not reached, the material returns elastically to its original shape after the load has been removed. If the yield point is exceeded, there remains a change in shape, i.e. an elongation in the case of a tensile specimen. In the present case, according to the invention, the first layer made of a material is designed in such a way that it is not permanently plastically stretched by a user during normal manual handling. In particular, such a layer, referred to here as stretch-resistant, has a material with its material at room temperature (23 ° C.)

Yield limit with a maximum of 3% elongation of over 15 Pa or N / mm ² , preferably of over 40 Pa, particularly preferably of over 80 Pa.

According to the invention, a further, second layer is applied on the outside of this stretch-resistant, first layer. With the first layer, the function is created that this is done by means of the adhesive layer on a substrate,

in particular a mobile device or a case of a mobile device, can be glued on without deforming. In particular, such a first layer cannot be stretched or warped by a user when it is glued on in such a way that it no longer fits on the associated substrate with regard to its contour and / or external dimensions. This ensures, according to the invention, that the protective device according to the invention can always be glued on with a precise fit. The further, second layer according to the invention at the same time makes it possible to use these with a high variety and variance of material or

Material can be designed. With the solution according to the invention, it is possible for the user of the protective device with the second layer to be offered a special haptic and / or visual experience. This second layer can be made from various materials and with various surfaces and offers the designer of the protective device according to the invention every imaginable freedom with regard to its optical design.

In addition, the second layer according to the invention provides further protection for the associated mobile device. The second layer can be used

in particular also be designed to be soft, resilient or flexible and thus particularly shock-absorbing. While the first layer is preferably designed to be comparatively thin and only has a thickness of less than 0.7 mm, preferably less than 0.5 mm, particularly preferably less than 0.3 mm, according to the invention, the second layer is advantageously comparatively thick designed and has a thickness of more than 0.5 mm, preferably of more than 1.0 mm, particularly preferably of more than 1.5 mm.

The second layer is preferably designed with a tensile strength that is lower than the tensile strength of the first layer. Thus, the second layer can also have a very low yield strength and can nonetheless, even by inexperienced users of the protective device, be applied with a precise fit on an associated substrate by means of the first layer mentioned.

The first, stretch-resistant layer of the protective device according to the invention is preferably formed from a film, a mesh or a paper. A film is understood here to mean a very thin sheet of metal or plastic. A net is a meshed textile fabric with regular meshes or openings. The meshes or openings of this network are preferably rhombic, square or hexagonal. Paper is a two-dimensional material that comprises fibers, in particular of vegetable origin, and is formed by dewatering a fiber suspension on a sieve. The resulting paper fleece is compressed and dried. The yield strength of the first layer, which is required according to the invention, can advantageously and inexpensively also be created by means of a thin plastic layer, which is as such it can be flexible, rollable, and can be pulled on and off, but is still little or no elasticity in the direction of the surface.

The adhesive layer of the protective device according to the invention is preferably designed with a removable adhesive. In this way, the

Protective device according to the invention can also be advantageously detached again from an associated substrate. The adhesive layer is advantageous by means of

Spray on the first layer to apply.

To, as explained, an appealing haptic and / or visual

To create the appearance of the protective device according to the invention for its users, the second layer is preferably designed with fibers, threads or flaars.

The second layer with a nonwoven material, a

Felt material, a fabric material, a fur material, an artificial leather material, a tarpaulin material and / or a Velcro material designed. In particular, the second layer can be used to create a soft surface that is perceived as pleasant to the touch. A layer of felt material is a flat textile structure made from a disordered fiber material that is difficult to separate. The individual fibers are intertwined with one another in a disorderly manner. So felt is a non-woven textile. If finished fabrics (e.g. loden) are felted, one speaks of boiled fabrics. Felt is made from man-made fibers and plant fibers by dry needling (needle felt) or by solidifying with water jets exiting from a nozzle bar under high pressure. Felt made from sheep's wool (wool felt) is a felt or press felt. In the present case, the felt material is preferably an industrial felt made of man-made fibers or an artificial one

Material such as polyester or other plastics selected. One such

Felt material is more resistant and robust than felt made from natural fibers.

Fabric material here refers to a product woven, knitted or knitted from textile fibers, rolled into strips. Such a substance is advantageous in addition one or more pockets. The pockets are preferably of such a size that a charger, a charging cable, a mouse and / or other accessories of the mobile device can be accommodated therein. Furthermore, the pocket is preferably designed as a business card pocket or pen pocket.

According to the invention, the fabric of used jeans trousers or other trousers is also advantageously used as the fabric. Alternatively, a substance can be deliberately designed as "used" or used in terms of its surface and external properties. Furthermore, according to the invention, a real or artificial fur material or fur is advantageously used as the second layer. As fur, in particular also referred to as fur, is understood here as the skin of mammals with a hair density of 50 hairs per square centimeter or more. Such a fur is of particular importance for humans insofar as they themselves no longer have a thick coat, but still have a tendency to touch or look at them. Artificial leather material or artificial leather is an imitation leather, usually a composite of a textile base carrier (e.g. fabric) and a

Plastic cover layer (e.g. polyvinyl chloride). The fabrics are preferably natural fibers, man-made fibers or mixed fabrics, which in many cases are coated with soft PVC. This coating is preferably made compact or foamed. The surface is particularly preferably given a grain embossing so that its structure also resembles real leather. By means of the coating is a wear-resistant surface with one underneath

created a softer, shock-absorbing surface. At the same time, a high-quality look and feel of real leather is possible. Synthetic leather is inexpensive and very robust, washable and dry without hardening. There

If artificial leather on textile carrier materials is a continuous material, the cutting is much easier than with real leather and the quality is always the same. In addition, artificial leather is not tied to the market availability of certain animal hides. In the present case, a tarpaulin is understood to be a textile covering or a cloth. Tarpaulins are usually weatherproof, durable and flexible to use. They are often used as sun and rain protection as well as

Advertising media on company buildings and as a cover on trucks used. In particular, hard-wearing tarpaulins in so-called truck quality are known. It is also known to produce so-called tarpaulin bags from these. According to the invention, such tarpaulins are preferably used as tarpaulin in truck quality, which in particular have already been used and / or

Have advertising imprints. The tarpaulin of this type can advantageously combine the first layer according to the invention in the form of a net or fabric and the second layer in the form of a rubber-like pad or coating. In the present case, hook and loop material is understood to mean a material by means of which a hook and loop fastener can be produced. A Velcro fastener is a textile fastener that can be loosened almost any number of times and is based on the principle of Velcro fruits. The typical shape of a Velcro fastener has two synthetic fiber surfaces, of which one surface has flexible barbs and the other surface has loops. When pressed together, the result is a more resilient, but reversible

Quick release. According to the invention, a surface with loops is preferably used as the second layer. The surfaces are preferably woven and in particular made from polyamide, polyester and / or polyolefin fibers. Fibers made from polyaramids are also advantageously used. Such surfaces are also known as flakes. The solution according to the invention thus achieved offers the possibility of attaching various things to the mobile device temporarily and releasably, e.g. various stickers, a charging cable, a transformer or one or more bags. The Velcro surface provided for this purpose, advantageous according to the invention, is preferably formed on an underside of the mobile device and only covers this underside completely or specifically

in sections.

The protective device according to the invention is also advantageously formed entirely and exclusively from materials that are biodegradable. A wool material, in particular a wool felt, a leather material and / or a wood material is provided as the second layer, a paper is provided as the first layer and a starch adhesive is provided as the adhesive layer. Furthermore, the first and second layers are preferably tailored to the outer contour of the electronic mobile device, in particular the laptop, or to the outer contour of a case of the electronic mobile device, in particular the laptop. The outer contour is understood to mean, in particular, the contour of the outer edge of the upper part of a mobile device, such as a laptop, in which its screen is located. Furthermore, the contour of the outer edge of the lower part of a

Mobile device, such as a laptop, understood, in which its keyboard is located. The two layers of the invention are cut in this way

Protective device led to the edge of the mobile device or its case and at the same time the side surface of the mobile device or case is not covered and therefore visible. This creates a visually particularly appealing and at the same time sufficiently protective protective device.

The adhesive layer is preferably on an upper side and / or a lower side of the electronic mobile device, in particular the laptop, or on a

The top and / or bottom of a case of the electronic mobile device, in particular the laptop, is glued on. One is glued on in this way

Protective device created that protects the associated mobile device and at the same time increases its thickness only slightly. A variety of visual and haptic designs are possible. The protective device can even be attached to the associated mobile device or oasis by inexperienced users.

According to the invention, a method for forming a protective device of an electronic mobile device, such as a laptop, in particular a protective device of the type mentioned above, is accordingly created, with the steps:

(1) providing a stretch-resistant, first layer which has a first side and a second side facing away from it,

(2) forming a flat adhesive layer on the first side, and (3) on the second side, forming a surface-connected, second layer, in particular the yield strength of the second layer being designed to be lower than the yield strength of the first layer.

In such a method, the first and second layers are preferably cut to the outer contour of the electronic mobile device, in particular the laptop, or to the outer contour of a case of the electronic mobile device, in particular the laptop.

Furthermore, the adhesive layer is advantageous on an upper side and / or a

Underside of the electronic mobile device, in particular the laptop, or on an upper side and / or an underside of a case of the electronic

Mobile device, in particular the laptop, glued on.

Detailed description of the exemplary embodiment

In the figures, a cover or a case 100 of a laptop 150 is shown. The case 100 comprises an upper part or an upper shell 110 for covering an upper part 160 of the laptop 150. The upper part 160 is designed with an inner framing surface 162 for a screen and a peripheral surface 164. The case 100 furthermore comprises a lower part or a lower shell 120 for covering a lower part 170 of the laptop 150. The lower part 170 is designed with an inner border surface 172 for a keyboard and a peripheral surface 174.

The upper shell 110 has a raised edge 112 on its circumference and four tabs 114 distributed there, by means of which it can be clipped over the circumferential surface 164. The lower shell 120 also has one on its circumference

raised edge 122 and distributed there two recesses 123 and four tabs 124, by means of which it is to be clipped over the circumferential surface 174. Furthermore, the lower shell 120 has four raised feet 126 on its underside (see FIG. 4). FIG. 2 shows how the case 100 is attached to the laptop 150 in this way. It can be seen in particular that the tabs 114 and 124 each encompass the laptop 150 there at the outer edges of the inner enclosure surface 162 and the inner enclosure surface 172.

FIGS. 5, 6 and 7 each illustrate a flat, thin protective device 500, 610 and 710, which is made up of several layers and is to be applied to the top or bottom of the case 100 or the laptop 150. According to FIG. 5, the protective device 500 has an adhesive layer 510 that is to be applied or glued to a substrate 520. According to FIG. 6, the base is the top of the upper shell 110 of the case 100 and / or 7, the bottom of the lower shell 120 of the case 100. Alternatively, the base 520 for the protective device 500 is the top of the upper part 160 of the laptop 150 and / or the bottom of the lower part 170 of the laptop 150. The protective device 500, 610, 710 protrudes in the direction of their flat

Extension in each case to the outer edge of the substrate 520 and in particular does not encompass this (see FIGS. 6 and 7).

The adhesive layer 510 carries a first, stretch-resistant layer 530, as explained above. A second layer 540, which is also designed as explained above, is applied to the first layer 530. The second layer 540 is in particular glued, laminated, vulcanized, flocked, felted or woven onto the first layer 530. With such a process, in particular, an integral, one-piece structure of the two layers 530 and 540 is created.

6 and 7 illustrate again how the protective devices 610 and 710 are to be glued and also removed again on a base 620 as the underside of an upper shell 600 of the case 100 or on a base 720 as the upper side of a lower shell 700 of the case 100 . The

The protective device 710 for the lower shell 700 has four openings 715 with which it can be applied to the substrate 720 around the associated feet 725 of the lower shell 700.
