Abstract

The moisture-tight protective sleeve consists of an elastic, transparent tubular sleeve (1) with a closed end (2) and an open end (3) and the open end is provided with a toroidal seal (4) formed by winding up the tubular sleeve.

Description

The The invention relates to a moisture-proof protective cover for portable electronic devices. The protective cover Can be used for mobile phone, PDA, GPS receiver and radios used when elevated under conditions Moisture, e.g. B. during the rain on the open Ceilings of water transport, in damp rooms, be used.

nowadays become the compact electronic devices, such as Cell phones, PDAs, etc. Widely used in the household and in the industry. To a normal function of such devices, which are sensitive to moisture are to ensure the inner parts of the Environment under adverse operating conditions, for example during the rain, in the forest, on open ceilings of water transport, be protected in damp rooms.

Therefore Become the compact electronic devices with moisture-proof Housings equipped.

In Patent [1] has described a moisture-proof housing. This known housing is made of hard and soft parts Material composed. The disadvantage of this case is that it is only for a mobile phone of certain form (for a specific model) and not for others electronic devices can be used.

Known is also a moisture-proof case for Mobile [2], which consists of an upper and lower part. These Parts are connected and can be opened again become. The disadvantage of this known housing exists in that it is only for a cell phone with certain dimensions can be used. It is also impossible to use the phone to use without opening the case, d. H. the well-known housing does not provide for protection of the mobile phone during operation. Other disadvantages protecting a compact electronic device Influence of moisture through the production of special Housing belongs to the increase in weight, the dimensions and the price, as well as the need for a protective housing for each device to have the housing after any adverse effect of the environment on the moisture to clean. This deteriorates the operating characteristics of these Equipment. At the same time, only certain devices can and relatively rarely protected from the adverse effects become.

With Help the well-known moisture-proof envelope for Mobile phone [3], the phone can be used without the moisture-proof To open housing. The case consists of a closed inner plastic bag with a front part. The front part is made of a transparent Material formed. The inner bag has an opening for inserting the mobile phone. The opening is made with the help of a clip closed. The inner bag will be in an outer Protective bag laid. Then it is connected by a thread. The disadvantage of the known shell is that the Use of inserted in the case phones difficult is when the phone is taken out of the case. The other shortcoming is the too large dimensions the shell and that it is uncomfortable, the shell to store. The reliability of the case is not sufficient. This is by applying a bracket to the side the opening for the mobile phone to ensure the Tightness of the shell conditionally.

The Application of a known moisture-proof casing for Mobile [4] ensures the ease of use of a Phones. The well-known shell consists of a moisture-permeable fabric and a plastic plate. Both parts are thermally welded together. At the side of the entrance / exit opening (opening, through which the phone is inserted into the case) becomes the Cover wrapped on a rod and based on this one Clamp fixed. The disadvantage of the known shell consists in limiting the width of the device, which is in the case is inserted. Therefore, the case for PDAs Not used.

The moisture-proof case for mobile phone according to [5] formed in the form of an envelope made of a film. The envelope is shrunk under the effect of an elevated temperature. This moisture-proof shell [5] comes the technical Sense of the invention closest. The disadvantage of this known shell is that it is complicated, the Shell to use. That's because of that Heaters with the necessary feed can be used have to. This limits the scope of use of the protective cover.

It Object of the invention, a moisture-proof protective cover to create the type mentioned, the use allows the device without removing it from the protective cover to be removed. This object is achieved according to the invention solved by being made of an elastic, transparent Tube cover with a closed end and an open End exists and that the open end with a toroidal seal is provided, on which the tube cover is wound. On This way it is achieved that the electronic device easily inserted into the protective cover and in the protective cover can then be conveniently operated.

The invention will nä with reference to an embodiment shown in the drawings her explained. Show it:

1 an overall view of the tubular casing,

2 the rolled-up, moisture-proof casing in side view,

3 a section along the line AA the 2 the tube cover,

4 in top view a cell phone in the protective case and

5 the protective cover after 4 additionally twisted and knotted at the open end.

The moisture-proof envelope for a portable electronic device includes a tube shell 1 with a closed end 2 and open end 3 ( 1 ). The tube cover 1 is formed of an elastic transparent material. The open end 3 the tube shell is with a Toroidalverdickung 4 connected. On the toroidal thickening 4 becomes the tube cover 1 rolled up ( 2 . 3 ).

The tube cover 1 For example, it may be formed from thermoplastic polyurethane, latex, as well as synthetic latex, which allow relative extension up to three times without destruction.

The toroidal thickening 4 serves the possibility of rolling up the tubular casing 1 in the manufacture of the protective cover, for fixing the shape of the protective cover in its storage and the convenience of mounting the waterproof protective cover on the electronic device 5 to ensure use.

Thanks to the elasticity and transparency of the tubular cover 1 can the electronic device 5 be used by putting it in pipe casing 1 remains.

If it is necessary, the tightness of the protective cover by the collapse of the tube cover 1 and by tying the tube cover together 1 with a knot 6 in the area in front of the toroidal seal 4 be guaranteed.

The flexibility of the tube shell 1 and the possibility of the length of the tubular casing 1 to adjust by partially untwisting in use, ensure that the tube cover 1 can be used for devices of almost all shapes and for devices of different sizes.

The protective cover is used as follows:
Before use, the tube shell 1 stored in the collapsed (rolled up) state. The rolled up tube cover 1 ( 2 ) is placed on an edge of the electronic device 5 pulled up and rolled up so that the whole device 5 through the tube shell 1 is covered ( 4 ). The presence of the open end 3 the tube cover 1 allows the main elements of the electronic device 5 (Keyboard, display, navigation key and menu keys) to protect from moisture. If necessary, other external devices such as headset, power adapter, GPS receiver etc. can be connected.

To ensure full protection against moisture, the open end 3 the tube cover 1 tied together and by a knot 6 locked. The unwinding can be done as follows: The open end 3 the tube cover 1 is held, and the electronic device 5 is together with the mounted tube cover 1 turned around its axis.

If the tube shell 1 according to the scheme in 4 if it is not damaged and wet, the pipe cover can be used 1 after using the protective cover back on the Toroidalverdickung 4 rolled up and used repeatedly to protect this or any other electronic device.

If the tube shell 1 according to the scheme in 5 is used, if it is damaged and wet or dirty, the pipe cover can 1 After use, disconnected from the electrical device (destroyed) and simply disposed of.

The proposed invention may be the use of moisture-proof Protect protective cover and for convenience the use of the portable housed in the protective cover electronic device. The electronic device can be different shapes and different sizes exhibit.
