• - with a fourth slider on the front wall ( 2a ) of the upper part ( 2 ) for menu button / home button is present,

The top ( 2 ) and / or the lower part ( 3 ) may be formed in one or more parts.

For example, the first upper shell ( 2 ' ) one half of the top cover of the smartphone cover ( 1 ). It consists of the lateral walls ( 2 ' ) and the front wall ( 2 B ). At the latter one can see a large section ( 2 'c ), which terminates directly with the touch screen, for example an iPhone. In addition, cutouts ( 2'd ) for the camera, speakers, proximity sensor and ambient light sensor. For example, there are policies directly from Apple to not affect the features of the device.

For ambient light and proximity sensor cutouts in the form of a cone or a truncated cone with, for example, an angle of 90 ° are provided here. For example, the angle for the front camera is 92 °. In addition, lateral free spaces ( 2'f ) may be provided, on which, for example, controls for the volume control are arranged, which can optionally be covered with sliders or kept open. Even from above, for example, there is such a free space, since there may be an on / off switch for the electronic device.

The first lower shell ( 3 ' ) can be one half of the bottom cover of the smartphone cover ( 1 ). Here also lateral and upper free spaces ( 3'f ) in the lateral walls ( 3'a ) of the envelope ( 3 ' ), which are provided for the individual operating elements. In addition, guides are provided for the slides, which go into the closed area of the wall in order to hide the slide in the open state as possible. The restaurant ( 3 'H ) can also at a lower portion of the shell ( 3 ' ) can be arranged.

For example, as safety pins for a rear camera and a flash unit overlap, the rear open spaces in the wall ( 3'G ) accordingly to a large section ( 3'd ). In order not to disturb the function of the camera, the safety cone advantageously has an angle of about 95 °. Just as with the camera, the flash unit may be about 95 °, but this is considered to be the minimum. Likewise, even an angle up to about 120 ° may prove advantageous in order not to reflect the light back into the camera.

For example, the second upper shell ( 2 '' ) with side walls ( 2''a ) a second half of the top cover of the smartphone cover ( 1 ). The envelope ( 2 '' ), for example, has a large section ( 2''c ) for the touchscreen. Just below it is still an open area ( 2''d '' ), which is intended for the home button. Adjacent to this, a smaller field in the form of a recess ( 2''e ) separated by a web, which serves the function of a sliding mechanism.

Here, the smaller field is provided as a Einrasthof for a slider. In addition, additional slides with a Einrasthof ( 2''f ), such as at the bottom of the envelope (FIG. 2 '' ). This can be used for headphone jack, microphone, speaker and interface for charging or connecting to other devices.

Also in this embodiment is an inner part ( 4 ) for the smartphone case ( 1 ), which is designed, for example, as a very small plate. The inner part ( 4 ) here also has a first recess ( 4e ) and an associated second recess ( 4d ), wherein the inner part ( 4 ) on the means ( 4e ) and ( 4d ) with the recess ( 2''d '' ) and ( 2''e ) from the top ( 2 '' ) cooperates in such a way that the first control element "menu button / home button" of a smartphone can be locked. It is inserted from the back into the second upper shell ( 2 '' ) and has the task to hold the slider in the correct position.

The lower shell may have a slot for insertion of the slider, which may also be present on all other slider guides on the inside of the respective wall. Furthermore, a hole is provided in the lower shell, which is adapted for example to the diameter of a home button.

The second lower shell ( 3 '' ) can be a perfectly closed rear wall ( 3''g ) exhibit. As in the case of the second upper shell ( 2 '' ), the counterpart to the second lower shell ( 3 '' ), the bottom wall ( 3''a ) Only partially available throughout, as there may be acoustic elements and connections.

The slider guide should therefore be designed to extend around the corners of the case. An angular elongated, but relatively flat form element ( 3 'H' ), as a connecting element, for example, projecting on slopes of the rear wall and during assembly of the smartphone case, and the second lower shell ( 3 '' ) with the restaurant ( 3 'H ) of the first lower shell ( 3 ' ) are connected by snapping.

The envelope, for example for a smartphone, can be designed in such a way that the top part ( 2 ) and the lower part ( 3 ) are positively connected via means in the form of a Einrasthof and counterpart or staggered webs.

The functions of the electronic device are fully retained by the case according to the invention, since the protective measures in the handling of the case do not affect the operability of an adult device while the case is applied to the device. In addition, there are options to make all applications of the device, preferably the smartphone accessible to adults, while small children, the operation of the same is not possible.

It has often happened that children who were not continuously supervised received or made unwanted calls. These are just examples of unpleasant situations. In order to exclude these and other scenarios, the child may only have limited operability.

By way of example, the problem arises that the majority of the functions can be controlled completely via the display. However, since not only the child-friendly applications are fully operable, but also the remaining applications should be unreachable, this creates an opposing interest.

Due to the aforementioned requirements, it is not possible to severely limit the achievable display surface. In the case of the selected smartphone model, however, it is usually the case that the applications can only be closed via the home button in order to return to the start screen. Therefore, the solution is to set up a variable operability for this job as well. In this case, the kid-friendly program would be started by the adult, then the smartphone in the safe state and transferred to the child.

For the production of the smartphone case according to the invention, the materials shown below can be used, for example.

Choosing the right material is crucial to making a good product. To make a good selection, some things like that have to be done CE guidelines 2009/48 / EC be taken into account. According to these guidelines, physical and mechanical properties must be fulfilled. For example, the material must withstand the stresses of use to ensure that smartphones and users, especially children, are protected. In addition, there are protection against inflammation and the fulfillment of chemical properties.

Preferred plastic materials are, for example

• - ABS is inexpensive, with different mixing ratios vary greatly the properties of this substance. In general, however, ABS has a high impact strength but also other mechanical properties, such as a high flexural strength, surface hardness, so that this substance is suitable as a base material for the casing according to the invention, in particular for a small-cell smartphone casing;
• - Polycarbonates (PC) belonging to the polyesters. PC has compared to others Plastic is a high price and is attacked by many organic solvents. Nevertheless, PC has a higher impact resistance than, for example, ABS. In addition, polycarbonates have a high temperature resistance;
• - Polylactide (PLA), a plastic that is made from renewable resources and is well recyclable. Versatile applicability results from innumerable good properties such as mechanical properties, low density and low flammability. Also positive is that PLA has low migration levels, which is why it is also popular in the food industry. Although PLA is still very expensive and has a low thermal limit of use, which is in the range of the present envelope for electronic devices rather of minor importance.

For example, the following techniques can be used to mount the envelope as protection for an electronic device:

Slide technique

This approach is based on the principle of a calculator. Here, the shell consists of two halves, one of which the electronic device, such as the smartphone permanently encloses and the other is changed depending on the type of use. The inner part is said to be similar to a standard one, with the exception of a reinforced rear wall. It is the base and could be used alone when used by adults. The functions as well as external interfaces are fully accessible and functional so that they can be used at every opportunity. The case completely encloses the device or mobile phone at the edge and is made of a softer material to ensure that the application without much trouble. The outer part is self-agile and not necessary for adult use, but can be attached to the back to prevent loss.

When mounted on the front should thus create a condition that optimizes the device, such as mobile phone for the childish handling. This component is made of a harder material to provide protection even in careless use. This shows the reason for the reinforced back of the inner part. The backside must be protected separately, as the outer part covers only front and sides. The electronic connections, as well as the side buttons and the home button are completely covered and thus inaccessible.

The fixation of the two parts to one another is determined, for example, by two rails which are attached along the sides of the inner shell. Along the outer shell is guided during the on and off. For the parental lock Einraster be incorporated at the end of said rails, which are symmetrical in the direction of movement, so that the fixation takes place in both cases. In order to make the detent unsolvable for children, a more inflexible material should be used, so that a corresponding force must be used.

Folding technique

Here, the case is attached to the back of the device, for example on the phone and a mostly leathery fabric then occupies the front and back and the electronic connections on the bottom. Depending on the model, the front is held in position by means of a Velcro fastener or button which tensions a band over the upper side.

In extension of this approach, this shell also covers the sides in the closed state. In addition, the closure is not via Velcro or push button, but by means of brackets. The supernatants reach over at the corners of the top, until they begin to cover the back. An overlay is also created on the sides to completely cover the interfaces. In this case, the back and front of the shell must be well matched to each other to prevent ingress of liquids as described in the requirements.

Due to the rigid and harder material, it requires another way of enabling the folding principle. As a solution, hinges can be selected. Over a gutter, which covers the lower terminal block in the closed state, the front and back is connected via two hinges.

The back ensures the fixation on the device, for example on the mobile phone. Similar to the connection with the front, the fixing takes place again by means of clamps, in this case at all four corners. The pages are hereby recessed on the case to leave the connections in the open state.

Sliding technology

By means of this technique, a complete enclosure of the device, such as the mobile phone, with the aim of enclosing the largest possible area with a part, so that it is as well protected and no large voltage spikes occur under load.

For this it is expedient, also the opening for the insertion and removal correspondingly small to keep. The top of the case contains the on / off switch and, in extension, the buttons for volume and key lock are located in the upper part of the page. The underside of the shell contains a plurality of devices, for example in the form of recesses for electronic connections.

The closing of the opening of the shell takes place here by a second part, which is connected via a belt with the shell. This in turn is attached to the back and is fixed at the front by a strong push button. This also serves as a child safety device.

The conclusion between the two parts of the shell should be realized with projections to get a good seal. Similarly, the connection between the shell and the device or mobile phone should be designed. The shape should be as accurate as possible, so that the shell can absorb the falls well and the device remains undamaged.

The sheath may be made relatively thick compared to the aforementioned techniques to provide further protection since, while the sheath is being deployed, no interfaces need to be reached.

Pressure-sliding technique

This technique can be considered as an extension of the aforementioned sliding technique. An advantage of this technique is the use of sliders to provide a variable accessibility of the buttons and connections on or to the device out.

The shell can be divided into two parts, which can overlap with each other. However, the two parts are the same size in this case, so that the attachment of all slides is feasible. To further stabilize this connection, a long snap can be provided for the backs of the back.

The sliders can each be designed individually for, for example, the volume buttons, the on / off switch and the electronic connections of the electronic device. All are based on the same principle.

Here it is first to find the dimension, which should be freely accessible with an open slide. On one side of this dimension, below the surface, a niche of appropriate length must be built into the shell to accommodate the gate when open.

On the opposite side is the small Einraster, which fixes the closed slide. It is also necessary that the latching part of the slider can not disappear in the niche. This can be done by suitable design of the corresponding free surface of the shell.

To change from the open to the closed state of the shell is only a simple and fast sliding necessary. To open the slide can be pressed down to overcome the Einraster can. For a corresponding recess must be provided on the bottom.

The simplest application for this is the slider of the volume buttons. The available distance is correspondingly long and therefore easy to calculate.

In the 4a . 4b and 5a . 5b schematically is another embodiment of the shell 1 shown for an electronic device.

As in 4a For example, the first upper shell (FIG. 2 ' ) one half of the top cover of the smartphone cover ( 1 ). It consists of the lateral walls ( 2 ' ) and the front wall ( 2 B ). At the latter one can see a large section ( 2 'c ), which terminates directly with the touch screen, for example an iPhone. In addition, cutouts ( 2'd ) for the camera, speakers, proximity sensor and ambient light sensor. For example, there are policies directly from Apple to not affect the features of the device.

For ambient light and proximity sensor cutouts in the form of a cone or a truncated cone with, for example, an angle of 90 ° are provided here. For example, the angle for the front camera is 92 °. In addition, lateral free spaces ( 2'f ) may be provided, on which, for example, controls for the volume control are arranged, which can optionally be covered with sliders or kept open. Even from above, for example, there is such a free space, since there may be an on / off switch for the electronic device.

In 4b represents, for example, the second upper shell ( 2 '' ) with side walls ( 2''a ) a second half of the top cover of the smartphone cover ( 1 ). The envelope ( 2 '' ), for example, has a large section ( 2''c ) for the touchscreen. Just below it is still an open area ( 2''d '' ), which is intended for the home button. Adjacent to this, a smaller field in the form of a recess ( 2''e ) separated by a web, which serves the function of a sliding mechanism. Here, the smaller field is provided as a Einrasthof for a slider.

In addition, additional slides with a Einrasthof ( 2''f ), such as at the bottom of the envelope (FIG. 2 '' ). This can be used for headphone jack, microphone, speaker and interface for charging or connecting to other devices.

Also in this embodiment is an inner part ( 4 ) for the smartphone case ( 1 ), which is designed, for example, as a very small plate. The inner part ( 4 ) here also has a first recess ( 4e ) and an associated second recess ( 4d ), wherein the inner part ( 4 ) on the means ( 4e ) and ( 4d ) with the recess ( 2''d '' ) and ( 2''e ) from the top ( 2 '' ) cooperates in such a way that the first control element "menu button / home button" of a smartphone can be locked.

It is inserted from the back into the second upper shell ( 2 '' ) and has the task to hold the slider in the correct position. The lower shell may have a slot for insertion of the slider, which may also be present on all other slider guides on the inside of the respective wall. Furthermore, a hole is provided in the lower shell, which is adapted for example to the diameter of a home button.

The first lower shell ( 3 ' ) can according to the 5a one half of the bottom cover of the smartphone cover ( 1 ). Here also lateral and upper free spaces ( 3'f ) in the lateral walls ( 3'a ) of the envelope ( 3 ' ), which are provided for the individual operating elements. In addition, guides are provided for the slides, which go into the closed area of the wall in order to hide the slide in the open state as possible.

The restaurant ( 3 'H ) can also at a lower portion of the shell ( 3 ' ) can be arranged. For example, because safety pins for a rear camera and a flash may overlap the rear open spaces in the wall ( 3'G ) accordingly to a large section ( 3'd ). In order not to disturb the function of the camera, the safety cone advantageously has an angle of about 95 °. Just as with the camera, the flash unit may be about 95 °, but this is considered to be the minimum. Likewise, even an angle up to about 120 ° may prove advantageous in order not to reflect the light back into the camera.

According to 5b can the second lower shell ( 3 '' ) a completely closed rear wall ( 3''g ) exhibit. As in the case of the second upper shell ( 2 '' ), the counterpart to the second lower shell ( 3 '' ), the bottom wall ( 3''a ) Only partially available throughout, as there may be acoustic elements and connections.

The slider guide should therefore be designed to extend around the corners of the case. An angular elongated, but relatively flat form element ( 3 'H' ), as a connecting element, for example, projecting on slopes of the rear wall and during assembly of the smartphone case, and the second lower shell ( 3 '' ) with the restaurant ( 3 'H ) of the first lower shell ( 3 ' ) are connected by snapping.
