PRIORITY INFORMATION 
       [0001]    This application claims priority of Provisional Application Ser. No. 60/755,765 filed on Jan. 4, 2006. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This invention relates to a DVD combination playing and viewing device comprising a pivotable and rotatable display. In particular, the invention relates to a DVD viewer having a display protected in the closed position and viewable in an open position occupying the same space in each position. 
       BACKGROUND OF THE INVENTION 
       [0003]    Display screens are in wide use in the electronics industry. In portable devices that include such displays, it is particularly important to protect the surface of the screen from wear. This protection has been accomplished by providing a protective cover for the display or by configuring the display such that it folds into the electronic device, for example, by pivoting the display, e.g., on a laptop or a similarly configured foldable DVD viewer, to close the device with the displays face adjacent to keyboard. A disadvantage of a device like this is that in order for the display to be viewable, the device must be in an open position. In the open position, the display is positioned at an angle with respect to the base of the unit and thus the device, in the open position, occupies substantially more space than when closed. Disadvantages of a separate protective cover include either that the cover is a separate piece that can get lost, that the cover itself can become damaged resulting in distorted or unviewable portions of the images coming from the display, and that the cover requires additional space. A disadvantage of the latter solution is that the device in open form occupies twice the amount of space. 
         [0004]    Notebook computers that have a pivotable and rotatable display used to ensure that others around a table can read from the display, are known. Examples of US patents describing such feature are U.S. Pat. No. 6,912,122 to Chen et al. and U.S. Pat. No. 6,804,861 to Hsu. However, the rotatable character of the display does not solve the problem of the large space occupied by the device when the device is open. 
       SUMMARY OF THE INVENTION 
       [0005]    It is an object of the present invention to provide a DVD combination playing and viewing device with a protected screen mode and at least one viewing mode, which can occupy essentially the same space when in either mode and that does not require separate screen protecting parts, and in which the DVD may be in a secure stable position. 
         [0006]    It is a further object of the invention to provide a DVD playing and viewing device with beneficial properties as apparent from the description below. 
         [0007]    An object of the present invention provides a device, comprising a DVD reader, and a pivotable and rotatable display attached to said reader, wherein the display may be pivoted between a protected mode and a viewing mode wherein the base and display occupy essentially the same space in both modes. The DVD reader may include a DVD holding station, the cover of the DVD holding station being at the site of the DVD reader to which the display can be fixed. 
         [0008]    When not in use, the device can be put in a protected screen mode, i.e. with the display viewing surface pivoted such that the front of the display viewing surface is in contact with and facing the top side of the DVD reader. When in one viewing mode, the device can have the back surface of the display in contact with the top side of the DVD reader. In this way, the display is backwards fixable to the DVD reader. In the latter position, the user can watch the DVD playing on the screen with a device that occupies essentially the same space as in the protected screen mode. In both positions, the DVD is stably fitted in the DVD reader, having a protected cover secured between the display and the DVD reader. 
         [0009]    Thus, in one respect, an exemplary embodiment of a device according to the present invention may comprise a DVD reader, the DVD reader comprising a DVD holding station, the cover of the DVD holding station being at the site of the DVD reader to which the display can be affixed, and a pivotable and rotatable display attached to said reader, wherein the display may be pivoted between a protected screen mode and a viewing mode wherein the reader and display occupy essentially the same space in both modes. 
         [0010]    In another respect, the exemplary embodiment may be a combination playing and viewing device, comprising a DVD reader, the DVD reader comprising a DVD holding station, a cover of the DVD holding station being at the site of the DVD reader to which the display can be affixed, and a pivotable and rotatable display attached to said reader, wherein the display may be pivoted between a protected screen mode and a viewing mode in which the reader and display occupy essentially the same space in both modes. 
         [0011]    These and other aspects and advantages will become apparent to those of ordinary skill in the art by reading the following detailed description, with reference where appropriate to the accompanying drawings. Further, it should be understood that the foregoing summary is merely exemplary and is not intended to limit the scope of the invention as claimed.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0024]    In the detailed description of the figures, like reference numerals denote like elements in the figures. 
         [0025]    Pivotable, pivot, pivoting etc, refer to the ability of the display of the device to revolve about an axis parallel to the plane of the top surface  80  seen in  FIG. 8  illustrating a DVD reader according to an exemplary embodiment of the present invention. In other words when viewing  FIG. 6 , pivotable refers to the ability of the display  2  to revolve about line  60  to  60 ′. 
         [0026]    Rotatable refers to the ability of the display  2  to revolve about an axis perpendicular to the plane of the top surface  80  of the DVD reader. In other words when viewing  FIG. 6 , rotatable refers to the ability of the display  2  to revolve about line  62  to  62 ′. 
         [0027]    Unlike other DVD players that open similarly to a laptop computer where the display face is pivoted up and open from a protected screen mode for a viewing mode, an embodiment of the present invention comprises a DVD player that occupies essentially the same space when in a protected screen mode and when in a viewing mode. This may be accomplished by pivoting the display of the DVD player up, rotating it 180 degrees and then pivoting the display down so that the rear face of the display is placed in contact with the top surface of the DVD reader. This viewing angle allows for a minimal use of space while keeping the largest screen viewing area and may be referred to as a tablet or backwards fixed viewing mode. 
         [0028]    The DVD player has a viewing mode in which the screen is pivoted but not rotated or backward fixed. It should be understood that in addition to the viewing mode in which the screen is backwards fixed or in tablet viewing mode, the DVD player may also be viewed throughout the full range of pivoting and rotating as long as the screen is in a position to be viewed. 
         [0029]    It will be understood, however, to one skilled in the art, that the present invention may be practiced without some of the specific details. In other instances, well known process operations and devices have not been described in detail in order not to unnecessarily obscure the present invention. 
         [0030]      FIG. 1  illustrates an embodiment of the device in the protected screen mode having a display  2  and a DVD reader  3 . The device may be made of any plastic, metal or otherwise similar or suitable material or combination of materials. Closure component  4  may receive closure component  4 ′ to hold the DVD player in a protected screen mode. Actuation of the closure components  4  and  4 ′ enables the display to be pivoted open and rotated. The closure component may be a push, slide, flip, pull, twist, press, latch, or otherwise activated closure component. At the back of the display, a pivot mechanism  5  facilitates opening of the display. The pivot mechanism may be any mechanism that performs or supports the performance a pivoting action. 
         [0031]      FIG. 2  is a top view of the device, further showing rotating mechanism  6  on a pivot mechanism  5 . Rotating mechanism  6  is what allows the display  2  to rotate about the DVD reader  3 . The rotating mechanism  6  may be any commercially available mechanism that rotates or facilitates rotating. The rotating mechanism  6  and pivot mechanism  5  are preferably metal and covered with a plastic housing. 
         [0032]      FIG. 3  is a side view of the device showing battery  20 . The battery may be any commercially available and suitable battery used in such electronic devices. It is preferably a rechargeable battery such as, but not limited to, lithium ion battery. In an alternative embodiment, the device may also be powered using an AC wall adapter or a battery pack or any other power source. 
         [0033]    In an embodiment in which rechargeable batteries are used, the rechargeable batteries may be recharged any time the device is connected to an external power source. The device may also charge the batteries, and receive power, if a mechanism implementing Universal Serial Bus (USB), FireWire, or other such interface standards are connected thereto. In an embodiment in which rechargeable batteries are used, the batteries should be of a capacity such that, if the device is disconnected from the external power source when the batteries are fully charged, the device can be powered for several consecutive hours without needing to be recharged. 
         [0034]      FIG. 4  is a side view, further showing a control  10  to adjust the volume. The volume control  10  may be a tuning scale or any other control that would achieve the same result. For example, it may be a button or a touch-pad. Also in  FIG. 4  is a headphone jack  12 , optical audio/video jacks  13  and  14  and a power adaptor interface  15 . Control  11  provides switching for audio/video jacks  13  and  14  between input and output modes. 
         [0035]      FIG. 5  is a side view, further illustrating power switch  16 . This switch may also be a vertical switch, or a push button switch, or any other similar switch. It may also be a button or any other suitable apparatus. Although the power switch can be used to turn the device on and off, the device may ignore attempts to turn it on when the device is closed. The device may also automatically power off when closed. These features can help prevent draining the batteries when the device is not in use. 
         [0036]      FIG. 6  is a back side view further illustrating the pivoting mechanism  5  and the rotating mechanism  6 . Protection members  7  and  7 ′ protect the reader if the screen is rotated. The protection members may be made of plastic, rubber, silicone, or any other suitable material. They are preferably present to provide a space, padding, or cushion so that the display  2  and the DVD reader  3  do not damage or scratch each other by close contact or otherwise; the protection members also serve to absorb any shock that is generated when the display  2  is folded down toward the DVD reader. 
         [0037]      FIG. 7  is a bottom view of the device, showing the battery  20 , feet  21 ,  21 ′,  22  and  22 ′, on which the device stands safely on, for example, a table. The feet may be made of plastic, metal, rubber, silicone, fabric, or any other similar and suitable material. They may be any size in diameter, although it is preferable that the feet are not too large, about ½-1 inch in diameter. Slits  23  and  23 ′ provide openings through which fresh air can be circulated in the device to cool the electrical circuits. 
         [0038]      FIG. 8  illustrates the device in a traditional open form with the screen  30  and speakers  31  and  31 ′ as part of the display  2 . There may alternatively be different speakers and a different quantity of speakers than what is shown in  FIG. 8 . The screen may be any liquid crystal display (“LCD”), plasma, or any other suitable screen. The display may opened by pivoting it about the pivot mechanism  5 . Also pictured in  FIG. 8  is a DVD reader  3 . The DVD reader  3  comprises a DVD holding station, which may utilize commercially available DVD reading technology to read the DVDs. 
         [0039]    The DVD reader may include any features known to those of skill in the art for providing audio and/or video playback from DVD&#39;s, CD&#39;s, CDr&#39;s, CDRW&#39;s or other similar digital media. Examples of these features may be: over 500 horizontal lines of crystal clear picture, compatibility with NTSC/PAL system, multiple subtitles/viewing angles, slow/fast motion play, zoom operation, parental lock control, and 100-240 V automatic power adjustable input. The DVD reader may be made by inserting off-the-shelf-components including DVD readers and various related processors and controllers. 
         [0040]    Cover  32  is also shown in  FIG. 8 , the cover being on the top side of the reader. The protective cover  32  can be opened by pushing an opening controller  36 , but it is preferable that it not be opened from the side surfaces This has as an advantage that when in a backwards fixed position (or a viewing mode), or in a closed position (protected screen mode), accidental ejection of a disc in the reader is not possible. Further the top of the reader has controls  33 ,  34 , and  35  for controlling the DVED, such as starting to play, finding the right track, adjusting the screen color and brightness, moving forward, backwards, fast forwarding, rewinding, holding, volume, etc. The controls may be for example touch keys as in keys  33  or turn and touch keys as keys  34  and  35 . The controls may also be of any other similarly effective nature and configuration, such as touch pads, knobs, switches, tuning scales, for example. 
         [0041]      FIG. 9  shows the display  2  partially rotated according to an exemplary embodiment of the present invention. The rotation of display  2  as shown in  FIG. 9  is facilitated by rotating mechanism  6 , described above with reference to  FIG. 2 . In the exemplary embodiment, the display rotates 180 degrees. It is preferable that the display  2  be rotated clock-wise, horizontally about 180 degrees and then pivoted back 90 degrees across a vertical axis. The pivoting mechanism  5  facilitates the pivoting of display  2  vertically, and preferably spans 180 degrees. 
         [0042]      FIG. 10  shows the display  2  rotated 180 degrees and partially pivoted according to an exemplary embodiment of the present invention.  FIG. 10  shows the display approaching a backwards fixed position.  FIG. 11  shows the display in a backwards fixed position according to an exemplary embodiment of the present invention. 
         [0043]    An exemplary embodiment of the present invention has been described above. Those skilled in the art will understand, however, that changes and modifications may be made to this embodiment without departing from the true scope and spirit of the present invention, which is defined by the claims.
