Description

The The invention relates to a computer with a base part with a Keyboard and with a folding relative to the base part about an axis Monitor part with a display of a flat screen, in which the Base part and the monitor part in the folded state cuboid, portable device form.

portable Computers are becoming increasingly popular. You usually have one Flat screen TV. They are available in the form of notebooks, laptops, palmtops and in another form. Such portable computers are becoming numerous on business or taken on private trips and used on the way, For example, on train rides in the railway or in interruptions and breaks in waiting rooms. Increasingly popular is also the work outdoors, at least one Part of the job to be able to spend in a pleasant holiday environment or even to the portable Computer leisure activities pursue.

Just In portable computers, it is problematic that this in the concrete case often only in battery mode, ie operated without a mains voltage connection can be or should. this leads to However, too dimly lit displays that are correspondingly low in contrast are. Already a relatively low incidence of light then leads to the fact that the screens or displays are difficult to read are.

Now, in conventional, so not portable, stationary computers, the problem is already known that in unfavorable light, the screens are difficult to read. To solve this problem suggests, for example, the DE 203 04 618 U1 a complicated, multi-part, equipped with two plastic or cardboard angle profiles collapsible monitor screen protection, which is firmly connected by Velcro or double-sided adhesive mounting tapes with the monitor side and top, thus reducing the disturbing influence of light sources on the monitor. In particular, a stationary foreclosure against neon tubes and other artificial light sources is thereby to be achieved. For portable computers, this conception is not suitable.

It is the same with one from the DE 202 05 230 U1 known proposal to improve the lighting conditions on the screen workstation. According to this concept, a glare shield is attached to a table clamp, which in turn can be mounted on tabletops of any thickness. With a swivel arm, the anti-glare system is then swiveled with a glare protection sail into the desired relative position to the monitor and protects it in such a way that blinds or curtains are no longer needed at the VDU workstations.

The DE 101 11 861 A1 also proposes screening devices close to the screen which are mounted on support frames and use opaque components such as curtains or roller blinds.

There none of the known devices a suitable glare protection for portable Computer provides, it is the object of the present invention, a generic computer to propose that sustainable and still less susceptible to glare.

These Task is solved by a computer, with a base part with a keyboard, with a foldable about an axis monitor part relative to the base part with a display of a flat screen, where the base part and the monitor part in the folded state a cuboid, portable device form, in which the base part and the monitor part in the unfolded State one for a user accessible Keyboard and one at a time for him Visible display available in which a glare protection is provided, in which the glare protection at least two stable states can assume, in which the glare protection in the folded state of the computer on the top and / or the bottom of the cuboid device flat rests, and in which the glare protection in the unfolded state of the Computer side and above the display this forward in Directed towards the user.

Thereby will be surprising solved the task. The special configuration of the glare protection makes it possible easy to transport the portable computer and still a glare-free image on the display available there too place where there is a need, including in the open air, in a railway compartment or in a waiting room at lectures.

By the invention thus becomes possible a laptop or other portable computer too use if the display is dimly lit, say because it can only be operated with low contrast in battery mode. Not only a low, but also a strong disturbing light incidence can be eliminated according to the invention or shielded or reduced. Nevertheless, will the mobility and functionality of the laptop not restricted.

Surprisingly, a problem is also addressed, which was previously regarded as insoluble. For example, laptops often become confidential materials and texts, occasionally also security-relevant information that may not be made accessible to an unrestricted group of people. When used in the railway, in aircraft or otherwise in public vehicles or rooms, however, there is always the danger that fellow travelers or neighbors interested in watching the display and read along there. The inventively provided anti-glare shields but not only the light from, but also blocks the eyes of curious fellow travelers. The user can now use his computer in more frequented trains, where this would have been a security risk.

Three alternative embodiments The invention are particularly advantageous depending on the specific objective.

A first embodiment is constructed approximately in the manner of a folding board. The computer is characterized in that the glare protection comprises a plurality of flat elements, which together form a folding harness, that the folding tableware is hinged with the flat elements on that edge of the monitor part or almost pivotally, which when you open the computer, the top of the Displays forms that the folding tableware with the flat elements folded is not larger than the outside of the monitor part and can be placed on this outside, and that the folding tableware with the flat elements a middle flat element ( 33 ) and each having a right and left pivotally hinged thereto lateral element which in the unfolded and pivoted by 240 ° to 280 ° state together with the base frame completely or largely frame the display and shield sideways and upwards.

The inventive conception is complete collapsible and takes up practically no space, as a computer without the extra Visual and glare protection. The visual and glare protection is in all directions, So given to the right, left and up.

If especially in this variant as materials cardboard, cardboard or plastic for the Glare protection selected is, also creates a low-priced Conception that is nevertheless durable and reliable.

The How it works is also for Layman easily comprehensible and self-explanatory, the production very easy and inexpensive.

A second preferred variant is about the manner of an awning or built an accordion-like folding blind. In this case the computer is characterized by the fact that the glare protection accordion-like collapsible and unfoldable again Package consists of elements that make this package of elements a middle one elongated Element with the length about the longer one Screen side of the display and two right-angled adjoining sides elongated elements with the length about the shorter one Screen side of the display shows that the package is in a state on the outside of the monitor part or the outside the base part detachable is attached or on the inside of the monitor part the display framing is arranged, and that the package by synchronous unfolding the three elements can be converted into their second, unfolded state, in which it looks like awnings an outward shielded field of view for spans the user.

The folded package can either inside the unit in the folded state recorded in corresponding recesses surrounding the display be, or else space-saving outside on the outside either the base part or preferably the monitor part. It lies then adjacent to the peripheral edge and surrounds there from virtually Outside all around the on the hidden inside of the monitor part lying Display.

A third preferred variant is equipped in the manner of a jumping fabric, such as he does a lot for in practice Trekking tents and also used in other outdoor areas becomes. The computer is characterized by the fact that the glare protection with a set of pre-stressed, self-extracting fabric equipped is that the set in a first state a flat, the size of the outer surface of the Monitor part and / or the base part adapted form and when the device is closed these outsides is arranged, and that the set in a second state a clamped tubular structure with circular or oval cross-section, in which the device in the unfolded state is adjustable.

These Variation is not only technologically quite appealing, it allows also a non-rectangular field of view of the user on his display, what kind of the eye is a change and additional scope in the spatial Construction opened, for example, by a non-circular, but oval cross-section the resulting structure, this cross section also not constant have to be.

It is also possible for all three variants, retrofitted an existing and existing conventional computer in a computer according to the invention. The glare protection can be designed as a retrofit kit, which is then adapted to the respective computer type and also by the consumer himself by on and off Construction of the retrofit kit can be easily installed.

One Another advantage is that the glare protection, for example with advertising messages and logos or with the wishes of the Consumer customized color and image representations provided, for example can be printed. The advertising messages can be those of the computer manufacturer be, for example, but also with retrofitting of Third companies analogous to the printing example of Mousepads.

When Material comes next to cardboard, cardboard and plastic and other material Consider, for example, textile fabric material with which other Auffaltungseffekte foam, neoprene or even aluminum.

Especially For textile materials, versions can be realized in which through integrated, embedded wires or glass fiber reinforced plastic fibers a jump allows becomes.

To the Attaching the anti-glare mechanisms can be various clamping devices be provided. Permanent applications are also possible like velcro closures, attached clamps or punched out forms.

at some versions, for example, the self-extracting and exciting device is also no concrete attachment required but the portable computer, for example, a laptop can in the clamped anti-glare device are inserted.

Further preferred features are specified in the subclaims.

in the The following are some embodiments with reference to the drawings closer to the invention described. Show it:

11 the embodiment of 9 in the unfolded state of use with the arch extended further back;

12 the embodiment of 9 in the unfolded state of use with the arch drawn further forward;

13 the embodiment of 9 in the condition of use with reduced round arch.

The 1 to 4 show a first embodiment of the invention. It puts 1 a perspective view of this embodiment in the folded state. It can be seen a computer, which consists primarily of a base part 11 consists. This base part 11 forms a device with another, described below part 10 , This is cuboid and as usual about the size of a briefcase, so 10 to 20 cm wide, 20 to 30 cm long and about 10 cm thick. In the 1 is this base part 11 arranged below. It is opened for use.

By means not shown hinge elements is a monitor part 16 on the base part 11 hinged. Will the monitor part 16 unfolded around the hinge axis, as usual with portable computers a keyboard 12 on the base part 11 enabled, which allows the entry of commands or data. Together with the keyboard 12 a control panel is also provided, for example a sensor field as a mouse replacement or a comparable device. The monitor part 16 carries on the keyboard 12 facing side of a display or a display 17 ; he is trained as usual in portable computers as a flat screen.

The user sits, for example, in a train in front of his computer, the hinge axis on the side facing away from him of the base part 11 runs so that when folded monitor part 16 the user directly on the display 17 looks and with the Hands well on the keyboard 12 and the controls 13 can get.

However, people next to or behind the user also have a very good view of the display 17 and also on the keyboard 12 so that they can understand the operations by the user in a manner that is very undesirable, especially in confidential or secretive operations.

Here now creates a glare protection 20 Remedy. First is in the 1 good to realize that the glare protection 20 practically takes no extra space in this state. It is in this embodiment of several flat elements 31 . 32 . 33 constructed, which are overlapping each other superimposed and on top of the outside of the monitor part 16 rest on the side of the monitor part 16 that is not the display 17 carries and is therefore visible in the folded state from the outside. This collapsed, collapsed configuration thus does not take up more space than a conventional portable computer without such antiglare. Also in terms of weight of the glare protection is virtually no more difficult than conventional portable computers. The flat, plate-like elements 31 . 32 . 33 are preferably made of cardboard or plastic or similar materials and together form a three-piece folding harness on the back of the monitor part 16 ,

2 now shows the further procedure and shows even more clearly how the individual flat elements 31 . 32 . 33 are constructed. First, the two upper flat elements 31 and 32 each unfolded to the outside, that is to say about a pivot axis, which largely coincides with the narrow sides of the monitor part 16 and at the same time as the portable computer. The Elements 31 and 32 stand after opening with their surface normals perpendicular to the surface normals of the display 17 or the back of the monitor part 16 ,

After these side parts or elements 31 and 32 can be folded up, then the monitor part 16 Altogether upwards as conventionally be folded around its hinge and thereby the keyboard 12 release. This situation is good in 3 to recognize.

You can also see that during or after this process now the third flat element 33 pivoted about an axis that is aligned with the front longitudinal edge of the monitor part 16 matches only this third flat element 33 the first two flat elements or side parts 31 and 32 contributes, which are thus lifted off in this pivoting process.

If this process continues, the state which results in 4 is shown. So the portable computer is now usable for the user. As usual, the keyboard is located 12 and the control panel 13 Now ready for use in front of him and he can have a largely undisturbed view of the display 17 of the monitor part 16 toss. The two side parts or elements 31 and 32 are at the pivotal movement of the third flat element 33 but now completely turned around and close with their free, not on the third flat element 33 hinged sides flush with the side wall of the display 17 on both sides. These two flat elements 31 and 32 stand in a plane that is perpendicular to both the keyboard level 12 as well as to the level of the display 17 stands and reliably prevents any glimpse of the user's neighbors on the display 17 and largely also on the keyboard 12 , At the same time, by the third flat element, which is the first two flat elements 31 and 32 connects above, one roughly parallel to the level of the keyboard 12 lying further level and this way is also the view from above from diagonally above the display 17 stopped and on the keyboard 12 largely difficult.

In the 5 to 8th a second embodiment of the invention is shown. First is in 5 turn to recognize that the computer with its base part 11 and the monitor part 16 is closed. A folded glare shield 20 is also in this case on the back of the monitor part 16 space-saving arranged so that it occupies neither additional space nor weight in appreciable extent.

6 shows here the unfolding process of the computer. You can see the unfolded computer with the keyboard 12 and the control panel 13 in front of the user and the user is on the display 17 of the monitor part 16 looks. The glare protection 20 was in this case on the outside of the monitor part 16 only hung up or hooked, in this case by means of mounting clamps 44 , How to get the 6 can remove the whole package, so the glare protection 20 Now, put the other way around, the mounting clamps 44 are doing over the top of the monotor 16 clipped and attached the awning-like conception.

How to get in the 7 then the accordion-like folded lateral element becomes 41 and 42 unfolded and pulled so forward. At the same time, this also unfolds the upper, likewise accordion-folded element 43 so that unfolds, which in their Ge velvet dimensions of the first embodiment in the 1 to 4 similar.

How one 8th In addition, even with an increased need for security, the lower side of the lateral elements 41 and 42 be drawn up and virtually completely prevents any glimpse of neighboring people and leaves only the user himself an insight.

The second advantage is also complete: there are no more annoyances due to lighting, sunshine or other resulting reflections or impaired color contrasts on the display 17 more is possible.

In the 9 to 13 a third embodiment of the invention is explained in more detail. Instead of rather rigid materials such as cardboard, cardboard or plastic, a flexible material is used here. A fabric is used which self-aligns by means of in-laid, sewn-in or otherwise integrated flexible wires or rods. Such rods may for example consist of glass fiber reinforced plastic fibers. In other context, such self-extracting substances are used for example in so-called trekking tents or in the camping area.

To wrap after molding, the wiring - also known as trekking tents - to a kind 8th shaped and then reduced back to a fraction of the original size.

How to get the 9 can refer, the portable computer in turn has a base part 11 (below) and a monitor part covering it (above). Together they form this here in the 9 closed device 10 , which is thus ready for transport or could be opened for use. At the top of the monitor part 16 and this largely covering - but not practically beyond this - is here a set 50 to recognize, from the later again the glare protection 20 arises. This packaged set 50 or the glare protection 20 As with the other embodiments, it is practically without additional space or weight requirements to be attached to the portable computer and transported therewith.

The set 50 consists primarily of a flexible, slightly flexible fabric 51 , In these is a rod or a wire 52 integrated, for example inserted, which can jump elastically between two states depending on the bias. In the wrapped state of the self-extracting fabric shown here, a back bar of fiberglass reinforced plastic fibers or a wire forms exactly the contours of the monitor part of the portable computer. The front is designed as a round arch and runs when wrapped around approximately across the back of the monitor part 16 of the portable computer. The later forming the bottom part of the glare protection 20 Adjusts the bottom of the base 11 of the portable computer and is therefore not visible in the figure.

10 shows how the user the glare protection 20 or the set 50 from the wrapped state to an unpacked, unfolded state. It forms thereby a kind of textile tube, which in turn is stable for itself and represents a second stable state.

In this cracked, unpacked textile tube of the set 50 or glare protection 20 becomes the portable computer with the keyboard 12 upwards and unfolded monitor part 16 set. An assembly of the glare shield 20 on one of the elements of the device 10 is not mandatory (but nevertheless possible in some embodiments), since the glare protection 20 in this case is self-supporting.

In the longitudinal direction (seen from the user from front to back), here is the glare shield 20 another, spirally bent wire acted, which stiffens the unpacked textile tube in the longitudinal direction.

12 shows that even the resulting glare protection 20 in some embodiments may be further developed. Thus, the field of view can be additionally rejuvenated in order to be able to design entries even under the most adverse circumstances, such as in the plane, unobserved. For this purpose, the front wire is hollow on one side and pushed onto the other wire to reduce the radius of the front arch. The fabric is put into folds.

13 shows the resulting result.
