Description

The The invention relates to a portable laptop computer with at least two screens and a keyboard for presentation purposes for customer consultations in the field, for example, by financial service providers or insurance agents or is also intended to hold lectures.

Known are portable computers with a second screen. For example, offers the company Sharp under the name MEBIUS a netbook, which in addition to the main flip-up main screen an additional Second screen owns. This is located in the main body, in the whole for the operation of a computer necessary hardware and software on one Level is housed with the keyboard. The second screen is located in the place that is usually the touch pad is located, this second screen also has the functions of the touch pad can take over.

adversely the small size of the second screen, on which only a small amount of information is displayed or accommodated can be. If the screen area is chosen larger, then there is no room left for an additional Keyboard available.

Known are also laptops in addition to Main screen on the total area of the ground housing body one huge Own secondary screens without keyboard. The second screen is as Touch screen trained and takes over the functions of a keyboard, a so-called soft keyboard. When using two larger screens The common problem with soft keyboards is that of these many not as an input option for larger texts be accepted.

A display device with a removable keypad connected via a wireless connection to two monitors is shown in FIG EP 1 190 296 B1 described. The two monitors are connected by a joint, which allows the monitors to be swiveled over more than 180 °, creating a control and presentation screen for two people sitting opposite each other.

Above that Second screen is provided a full-featured keyboard, which wirelessly with the basic device connected is. This keyboard can either be on one of the two Screens are pushed or pushed. It needs its own Power supply as well as additional Connection hardware and software. Because the two screens together is a mobile presentation on the second screen not possible. The server is local to the device bound. At full-surface Use of both screens is a keyboard placement only outside of the basic device possible.

EP 0 947 909 A2 describes a portable laptop computer with a main body and a main screen, wherein on the main body between two hinges, a second screen and a keyboard are arranged, The second screen is trasportabel as part of the portable laptop computer. The keyboard is fixedly but pivotally connected to the main body of the laptop computer via a hinge, the keyboard being mutually positionable on the main body or nearly flush with the hinges of the main body.

DE 103 14 554 A1 discloses a laptop computer having a main body and a detachable keyboard which is radio-coupled to the main body, a hinged main screen and a second screen located under the removable keyboard in the main body.

The The object of the invention is a portable laptop computer with a fixed and a portable screen to develop in at the same time a keyboard is housed loss-proof. The laptop computer should be made compact while the Fixed and portable screen and keyboard in one Transport unit summarize, with the greatest possible usability on tightest Space should be possible with little equipment.

According to the invention Problem solved by the features of claim 1. Outstanding features are in the subclaims 2 to 5 described.

Of the portable laptop computer possesses a basic body and one in usual Way at the base hinged main screen. Located in the body yourself for the hardware and software required for operating a laptop computer.

Of the body of the laptop computer has a trough-like recess. These Recess is in height so dimensioned that a second screen and a keyboard are completely in it can be accommodated and the main screen completes the laptop computer in the usual way.

Of the Second screen forms a self-contained transportable unit. It is wirelessly connectable and disconnected from the laptop computer removable from him.

The Keyboard is over one or more hinges, preferably two, with the main body of the laptop computer hinged but firmly connected. These are pivotable on one side of the body Double hinges provided. Has such a double hinge a hinge leg, which by means of both the base body an eyelet as well as on the keyboard by means of a hinge suspension pivot is attached. The eyelet is at the body positioned so that the keyboard alternately at the bottom of the recess or almost flush to the surface of the basic body can be fixed. Depending on your needs, the keyboard or the Screen thus on the surface of the basic body are located.

The total height of keyboard and second screen is preferably equal to the depth the recess, making the laptop computer complete and tight lockable is.

Preferably is the eyelet approximately in the middle of the depth of the recess.

The Axle through the eyelet and the thigh suspension is designed so that the horizontal bottom of the base housing a Angle α <90 ° formed becomes. The area in the main body below the eyelet is therefore oblique educated. On the opposite side of the recess is a support surface provided on which the keyboard is placed, if the keyboard above the second screen. With the slope formed by the angle α that reaches the footprint is increased at the bottom of the recess. This will fit the keyboard when under the second screen should be placed in the recess. The keyboard can do this into the main body but their length is still enough to keep them up the bearing surface store.

The Keyboard is preferably over Connection cable on the main body connected. It can be powered by it and all transfer required data.

The Size of the second screen preferably fills the recess so completely from that slipping of the second screen in the recess is prevented.

The same applies to the keyboard, whose size is the recess so fills out, that slippage of the keyboard is prevented in the recess.

following the invention is based on an embodiment explained in more detail.

1 shows a schematic diagram of the main body 1 a laptop computer.

2 shows a section through a laptop computer with a practical embodiment of a hinge. A main screen connected in the usual way is indicated.

The main body 1 of the laptop computer has a trough-like recess 8th , by their shape and size a keyboard 4 and a portable second screen 2 can record. The second screen is wirelessly connected to the laptop computer. At one end of the recess 8th There are two eyelets on the base body 5 , on each of which a hinge leg 3 the keyboard 4 with the main body 1 combines. The second eyelet is congruent with the one in 1 eyelet shown 5 and therefore not shown. At the keyboard 4 is the hinge leg 3 by means of a hinge suspension 7 hinged. The hinge hanger 7 becomes like the eyelet 5 designed as a double bridge with locking pin. The eyelet 5 is positioned on the base body so that the keyboard 4 can be mutually fixed to the bottom of the recess or almost flush to the surface of the body. For this purpose, the eyelet is approximately in the middle of the height of the recess 8th , The shape of the hinge thus allows it even when removed second screen 2 that the keyboard 4 on the bottom of the recess 8th or on the support surface 6 can be stored.

The shape of the recess 8th in the rotation range of the hinge leg prevents slipping of the keyboard in the upper position. For this purpose, the angle α of the axis through the eyelet 5 and the thigh suspension 7 to the horizontal base of the base housing and thus also the keyboard 4 and the second screen 2 about 75 °. The area in the base body below the eyelet is therefore formed recessed further than the area above the eyelet 5 , The area above the eyelet 5 is about the width of the support surface 6 less recessed, so that for the keyboard 4 provided overall width in both positions is about the same size.

A flexible cable provides the connection between keyboard 4 and laptop computer. The cable is doing with one end between and at the height of the eyelets 5 into the main body 1 introduced. The other end is at the front of the keyboard 4 connected, approximately at the point where the hinges are attached.

The Invention has the advantage that there is a fixed keyboard, through joints with the main body connected and that can not be lost. The operator has a fully functional keyboard always on the laptop computer and can also enter longer texts easily, without the disadvantages of a soft keyboard to have to accept.

For the keyboard No extra power is required. The transportable Secondary screen can be both in the main body and outside operate.
