Abstract

In 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 is formed on the first side and is flat on the second side a second layer is formed adjacent.

Description

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.

To protect electronic mobile devices, such as portable 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 stuck 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 that is clipped onto and around the top or bottom of the mobile device. 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

This object is achieved according to the invention with 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, with an adhesive layer being formed flat against the first side and wherein a second layer is formed flat against the second side.

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 break. 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 characteristic value and describes 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, designated here as stretch-resistant, with its material at room temperature (23 ° C) has a yield point 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 on.

According to the invention, a further, second layer is applied on the outside of this stretch-resistant, first layer. The first layer creates the function that it can be glued to a substrate, in particular a mobile device or a case of a mobile device, by means of the adhesive layer, without deforming in the process. In particular, such a first layer cannot be stretched or warped by a user when sticking it on in such a way that its contour and / or external dimensions are no longer on the corresponding underground fits. 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 enables it to be designed with a high variety and variance of material or material. 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 all 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 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 flat material that includes fibers of vegetable origin in particular and is formed by dewatering a fiber suspension on a sieve. The resulting paper fleece is compressed and dried. The tensile strength of the first layer required according to the invention can advantageously and inexpensively also be created by means of a thin plastic layer, which as such can be flexible, rollable and can be pulled on and off, but is still little or no elasticity in the surface direction.

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 advantageously be detached again from an associated subsurface. The adhesive layer is advantageously applied to the first layer by means of spraying.

In order, as explained, to create an appealing haptic and / or visual appearance of the protective device according to the invention for its users, the second layer is preferably designed with fibers, threads or hair.

The second layer is particularly preferably designed with a fleece material, a felt material, a fabric material, a fur material, an artificial leather material, a tarpaulin material and / or a Velcro material. 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, an industrial felt made of man-made fibers or an artificial material such as polyester or other plastics is preferably selected as the felt material. Such a felt material is more resistant and robust than felt made of natural fibers. Fabric material here refers to a product woven, knitted or knitted from textile fibers, rolled into strips. The material of this type is advantageously also provided with 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, since they themselves no longer have a thick coat, but they still do a tendency to touch or look at one. 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. The coating creates a wear-resistant surface with a softer, shock-absorbing base underneath. 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. Since artificial leather is available as a continuous material on textile carrier materials, 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 and as advertising media on company buildings and as a cover on trucks. 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 resilient, but reversible quick-release fastener. 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 adhesives. The solution according to the invention thus achieved offers the possibility of attaching various things to the mobile device temporarily and releasably, for example 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 covers this underside completely or selectively only 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 outer contour is understood in particular to be the contour of the outer edge of the lower part of a mobile device, such as a laptop, in which its keyboard is located. The two layers of the protective device according to the invention are cut in this way up to the edge of the mobile device or its case and at the same time the side surface of the mobile device or the case is not covered and thus visible. This creates a visually particularly appealing and at the same time sufficiently protective protective device.

The adhesive layer is preferably adhered to an upper side and / or an 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 in this way, a protective device is created which 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 be stuck to the associated mobile device or case even by inexperienced users.
