       BACKGROUND OF THE INVENTION 
       [0005]    1. Field of the Invention (Technical Field) 
         [0006]    The present invention relates to a cabinet comprising a holder for attachment to the holder of a device comprising a display screen, such as a television device or a computer monitor. In cases where a television device is mentioned hereafter a device comprising a display screen is meant and also other devices with a display screen other than a television device, such as a computer monitor are considered to be included. 
         [0007]    2. Description of Related Art 
         [0008]    Such cabinets have been known. In many cases it concerns cabinets in which a dedicated position is reserved for a television device, so that when the device is not in use, the television device with the screen remains visible. A switched off television screen usually does not provide a pleasant sight. 
         [0009]    Other television cabinets are known, wherein when the television device is not in use can be screened off by means of closable doors that close in front of the screen or by a venetian blind that can slide up and down. 
         [0010]    The known television cabinets have the disadvantage that they are arranged for accommodating a television device. 
         [0011]    GB 2 427 127 A1 describes a mounting for a retractable user interface with means to slide away part of a surface to create an opening in the surface in which the user interface can be deployed. 
         [0012]    WO 2010/046731 A1 describes a computer table with a working surface of which a proximal part can pivot upwards to create space so that a distal part can move between a lower position and a raised position, whereby the distal part comprises a computer display. After the movement of the distal part a proximal part can move back to its original position. 
         [0013]    US 2008/0116771 A1 describes a cabinet in which a flat screen television device is mounted at the inside of a top panel of the cabinet. The top panel is mounted pivotally to the body of the cabinet. A lifting mechanism attached between the top panel and another part of the cabinet entirely lifts up the top panel or provides assistance to open the top panel. 
       BRIEF SUMMARY OF THE INVENTION 
       [0014]    There is a need for a cabinet that can be equipped with a television device, but that also is usable for other purposes than accommodating a television device and wherein the television device is not visible when it is not in use. 
         [0015]    This need is met by a television cabinet according to claim  1 . The advantage of such a cabinet is that it comprises a horizontal panel, through which the cabinet can be used as a table, a coffee table or a side table. It is also possible that the cabinet is part of a buffet table or a wall cabinet, wherein the horizontal panel can be used to support a variety of things. In the operating condition the holder (to which during use a television device has been attached) is situated at a certain height above the panel, for example approximately 20 cm so that an ample number of articles can be accommodated on the panel without this bothering the function of watching the television screen. When the holder is in the storage position, there is nothing on or at the cabinet that gives the impression of a television cabinet. Inside the cabinet according to the invention use is made of only one drive that enables all the movements that are possible with the television cabinet according to the invention using this single drive. 
         [0016]    In the embodiment as described in claim  2 , the holder is slidably connected with the bracket and thus the holder, during moving to the operating position, can move upwards along the bracket by means of the pulling cable. Through this a higher position of the holder above the horizontal panel is obtained, without requiring additional space in the storage position under the horizontal panel. 
         [0017]    In a preferred embodiment the horizontal panel is moved away and moved back again in such a way that the horizontal panel maintains its horizontal orientation. When the horizontal panel is divided into two parts the maintenance of the horizontal orientation is in any case valid for one of the two parts. Because of this the various pieces that are positioned on the panel do not need to be removed and can remain where they are during movement of the television device from the storage position to the operating position and vice versa. 
         [0018]    A special advantage of the cabinet according to the invention is that during movement of the holder (during use with the television device attached) from the storage position to the operating position and back again, only the horizontal panel, respectively a part thereof, moves outside the vertical contours of the cabinet. However, it is easily arranged that this is not posing any problems. The holder (during use with the television device attached) itself remains completely inside the vertical contours of the cabinet. 
         [0019]    The cabinet according to the invention, it is preferred that in the storage position not only the holder but all elements of the device for moving the holder between the storage position and the operating position and vice versa, are placed below the horizontal panel and are thus not visible from the outside. When the holder is in the operating position it is clear that the holder itself is visible and also the bracket will be visible. In a preferred embodiment of the invention in addition to the bracket, the pivoting arm and the first pulling cable are visible above the horizontal panel, while all other parts of the device remain below the horizontal panel. It is possible that the horizontal panel comprises an opening through which these parts in the operating position of the holder are extending upwards. It is also possible that the horizontal panel comprises a pivoting part that in the operating position the holder is turned out of the plane of the panel to provide passage to the parts extending through the horizontal panel, being the bracket, the pivot arm and the first pulling cable. 
         [0020]    Preferably the drive comprises an electromotor with a transmission that connects the electromotor with the slide. This transmission can comprise a pulling cable for transmitting the movement of the electromotor to the slide, but this can also be done using, e.g., a screw spindle. 
         [0021]    When the horizontal panel, respectively a major part thereof, remains horizontal during the movement, pieces that have been placed thereon can remain in their position during this movement. In the case of the embodiment, for example where the cabinet functions as a coffee table, drinks could be located on the table, such cups of coffee, tea or glasses with other drinks. In that case it is advantageous that the cabinet according to the invention is arranged in such a way that during the movement there is no or a very limited possibility that some of the drinks are spilled over the table. Therefore it is in a preferred embodiment of the invention that the drive comprises a control such that the part of the horizontal panel that keeps its horizontal position during movement is controlled in such a way that this undergoes only limited acceleration that does not exceed a predefined threshold value. In such a way a preferred embodiment of the invention can be arranged so that the movement is very smooth and all matters that are positioned on top of the horizontal panel can keep their position.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0030]    In a preferred embodiment of the cabinet according to the invention the drive can be operated by remote control, so that using a remote control device the user can switch from storage position to operating position and from operating position to storage position. 
         [0031]    First, it is noted that not all figures comprise all reference numbers. For each series of figures only reference numbers are indicated thereon where they are most clear for understanding the operation of the embodiment of the invention shown. 
         [0032]    The overall operation will be described with reference to  FIGS. 1   a - e.    
         [0033]      FIG. 1   a  shows a cabinet  1  with a horizontal panel  2  that is divided in two parts,  2 ′ and  2 ″, in which below the horizontal panel  2 ′,  2 ″ a display screen, visual monitor or television device  3  is situated in the storage position. The horizontal panel in this embodiment is divided into two parts, being a part  2 ′, which comprises the largest part of the horizontal panel, and a part  2 ″ that forms the smallest part of the horizontal panel. The division between the parts  2 ′,  2 ″ of the upper panel is chosen in such a way that the part  2 ″ is as small as possible, but in the operating position those parts of the device for moving the holder and television device that necessarily have to be located behind the television device, are located below or above the parts  2 ″. The rear side of the television device in the operating position is essentially right above the dividing line between the parts  2 ′,  2 ″ of the horizontal panel. The horizontal panel  2 ′,  2 ″ is rectangular in shape and in the stationary position is at the bottom side in contact with four vertical panels that extend downwards. These panels are part of a frame  4  that is comprised in the stationary part of the cabinet. The cabinet  1  shown in the figures can be part of a table, such as a coffee table, but the part shown can also be part of for instance a wall cabinet. In the figures the part shown is limited to the parts that are essential for understanding the operation of the cabinet according to the invention. The frame  4  is fixed to the cabinet and is therefore supported by those parts of the cabinet that have not been shown in the figures. 
         [0034]    The drive is formed by an electromotor  5  that via transmission, can operate a screw spindle, that is not visible in the drawing, that is connected with slide  7 . Slide  7  is slidably connected with a guide  6  and can move via guide  6  from a first stationary position, shown in  FIG. 1   a  and which is close to one end of the guide  6  near to the drive with electromotor  5  when in the stationary cabinet storage position with the visual screen/television device  3 , to a second stationary position that belongs to the operating position of the visual screen/television device  3  and is situated near to the other end of the guide  6 . In the storage position the screen of the visual screen/television device forms an angle with the horizontal plane, thus with the horizontal panel  2  in position of rest, of approximately 10 degrees. With such a small angle the required space for the visual screen/television device  3  in the storage position is minimal, while the angle is sufficient to exert an upward force on the television screen  3  with movement of the slide  7  from the first stationary position over guide  6  together with pivoting arm  10 . In this embodiment the angle that pivoting arm  10  forms with the visual screen/television device  3  and holder  8  is decisive. This angle can be achieved in different constructive ways, which different ways are forming equivalents of the present invention. Slide  7  can also be moved in the reversed direction by electromotor  5  from the second stationary position that belongs to the operating position of the television screen  3  to the first stationary position that belongs to the storage position of the visual screen/television device  3 . Slide  7  is pivotally connected with bracket  9  along which holder  8  of visual screen/television device  3  is movable in the longitudinal direction. Further details of the moving mechanisms will be explained below. 
         [0035]    In moving slide  7  from the first stationary position, as is shown in  FIG. 1   a  to the second stationary position as is shown in  FIG. 1   e , by this movement an mechanism is activated that has as consequence a number of movements. In  FIG. 1   b  can be seen that the part  2 ′ of the horizontal panel has translated upwards and somewhere to the left in the drawing, remaining parallel to its original horizontal position. At the same time the horizontal part  2 ″ pivots around an axis that is situated at an end of the part  2 ″. At the same time holder  8  with visual screen/television device  3  has slid upwards along bracket  9  and bracket  9  is pivoted upwards along the pivoting connection with slide  7 . The movements that are described between  FIGS. 1   a  and  1   b  are continued between the  FIGS. 1   b  and  1   c . In  FIG. 1   c  therefore the part  2 ′ of the horizontal panel has moved further upwards and outwards and the part of the horizontal panel  2 ″ is pivoted practically vertically upwards, while holder  8  with the visual screen/television device  3  has slid further upwards along bracket  9  and bracket  9  is pivoted upwards further so that it forms a larger angle with the horizontal plane. In  FIG. 1   d  the upward movement of the holder  8  with the visual screen/television device  3  along bracket  9  has continued and also the erection of bracket  9  has continued to a position that is closer to the vertical position. The part  2 ′ of the top panel has moved back with respect to the position that is shown in  FIG. 1   c  to a position that approximately coincides with the position that is shown in  FIG. 1   b  and the same goes for the position of the part  2 ″ of the top panel. In  FIG. 1   e , finally, is shown that slide  7  is located in the second stationary position along guide  6  and the parts  2 ′ and  2 ″ are back to the horizontal starting position that is shown in  FIG. 1   a  and the visual screen/television device  3  is now in the operating position. 
         [0036]    The movement of the visual screen/television device from the storage position to the operating position is illustrated in the  FIGS. 2   a  up to and inclusive  2   j . The parts that are playing an active role are best visible in the  FIGS. 2   d  and  2   i . With the electromotor  5  driving a further not visible screw spindle, slide  7  is moved over guide  6  from the first to the second stationary position. Slide  7  is at pivot point  51  connected to bracket  9  along which holder  8  with visual screen/television device  3  is slidably movable. At pivot point  52  pivot arm  10  is pivotally attached to bracket  9 . Pivot arm  10  comprises two identical parts that each are pivotally attached to one side of bracket  9 . The other end of pivot arm  10  is fixed to a horizontal yoke  11  that in its longitudinal direction is perpendicular to the longitudinal direction of bracket  9 . At each of the ends of yoke  11  a yoke leg  12  is fixed. Each of the yoke legs  12  forms a right angle with yoke  11  so that the yoke legs  12  essentially are parallel to pivot arms  10 . At an end away from the yoke  11 , yoke legs  12  are pivotally attached to frame  4  in pivot points  53 . In the middle of yoke  11  a cable rod is fixed that stands off from yoke  11  approximately in a direction opposite to that of the pivot arm  10 . At the end of cable rod  13  away from yoke  11  a pulling cable  14  is attached that runs from cable rod  13  to an end of bracket  9  that is away from slide  7 , and pulling cable  14  runs from there and is attached to holder  8 . When starting from the stationary storage position using the electromotor  5  means the screw spindle moves slide  7  from the first stationary position to the second stationary position, then the combination of pivot arm  10 , yoke  11  and yoke legs  12  force bracket  9  to move from its almost lying starting position to a vertical position in which the visual screen/television device gets to its operating position. Pulling cable  14  at the same time pulls holder  8  and the attached visual screen/television device  3  upwards along bracket  9  until the operating position that is displayed in  FIGS. 2   i  and  2   j.    
         [0037]    In the description of the parts of the moving arrangement and rod system that makes both parts of the horizontal panel move back and forwards, most parts are executed in pairs and one part at each side of the cabinet. Both parts are identical and symmetrical with respect to a vertical centre plane of the cabinet. However, only one side will be described. The unit that is formed by pivot arm  10 , yoke  11  and yoke legs  12  is also responsible for driving the movement of both parts of the horizontal panel  2 ′,  2 ″. At the end of each of the yoke legs  12  that is away from the pivot point  53 , an end of the connection rod  15  is pivotally connected at pivot point  54 . At the other end connection rod  15  is pivotally connected with an end of the central rod  16  at pivot point  55 . Central rod  16  is at the other end pivotally connected to the frame in pivot point  56 . Central rod  16  that is moved via connection rod  15  by yoke legs  12 , is connected with those parts of the rod system that make move both parts  2 ′,  2 ″ of the horizontal panel. 
         [0038]    The major part of the horizontal panel, part  2 ′, is moved parallel to itself and keeps a horizontal position during the movement. Through the objects that are located on part  2 ′ of the horizontal panel can remain there during movement of the panel. 
         [0039]    The parts that belong to the movement mechanism of part  2 ′ of the horizontal panel are being described with reference to  FIGS. 3   b  and  3   g . Close to pivot point  55  one end of a first drive rod  17  is pivotally connected to a lip that extends from central rod  16  in pivot point  57 . The other end of the first drive rod  17  is pivotally connected to pivot point  58  of a lip near the end of the second drive rod  18 . Second drive rod  18  is at the end that is lies near to pivot point  58  pivotally connected to frame  4  at pivot point  59 . At the other end the second drive rod  18  is pivotally attached to an end of the third drive rod  19  at pivot point  16 . The third drive rod  19  is at the other end pivotally attached to panel slide  20  at pivot point  61 . Panel slide  20  is in its longitudinal direction slidably connected to panel guide  21 . Further panel slide  20  is fixed to part  2 ′ of the horizontal panel via connection plate  22 . Through the movements of central rod  16 , when this is driven as described before, via first drive rod  17 , second drive rod  18  and third drive rod  19 , as well as via panel guide  20 , part  2 ′ of the horizontal panel is moved from its starting position as is shown in  FIGS. 3   a  and  3   f  to a position in which panel part  2 ′ partly comes to a position above and outside the cabinet so that a passage is being formed for visual screen/television device  3  with holder  8  and bracket  9  to move from the storage position to the operating position. In the second part of the movement as is shown in  FIGS. 3   c - d  and  3   h - j  the panel moves back again to its starting position. During the whole movement panel part  2 ′ will maintain its horizontal position. Further it will be clear that the part  2 ′ of the horizontal panel is only connected with frame  4  and therefore with cabinet  1  via connecting plates  22  and the moving mechanism. 
         [0040]    Now, with reference to  FIGS. 4   a  and  4   f , those parts of the moving mechanism will be described that are responsible for moving the panel part  2 ″ of the horizontal panel. Further it should be noted that in  FIG. 4   f  an opening is visible in panel part  2 ″. In the storage position these opening are being filled by a part of panel  2 ″ that can swing away, which for the sake of clarity is not explicitly shown. This part that can swing away will during movement from the storage position to the operating position be pushed up by the pulling cable  14  and when returning from the operating position to the storage position be pulled in position again by a spring element that also is not explicitly shown. The movement of panel part  2 ″ will be described starting from the movement of the central rod  16 . The movement of the central rod  16  is described above and linked to the movement initiated by the drive via slide  7 . At a predetermined pivot point  62  at the central rod  16  an end of fourth drive rod  23  is connected pivotally. Fourth drive rod  23  is at its other end pivotally connected with an end of toggle link  24  at pivot point  63 . Toggle link  24  is near the toggle point of toggle link  24  pivotally connected with frame  4  in pivot point  64 . The other end of toggle link  24  is pivotally connected with an end of the fifth drive rod  25  in pivot point  65 . Fifth drive rod  25  is at its other end pivotally connected with panel part  2 ″ in pivot point  66 . Pivot point  66  is situated near the dividing line of panel part  2 ″ with panel part  2 ′ in the starting position. In  FIGS. 4   a  to  4   e  and  4   f  to  4   j  can be seen that the panel part  2 ′ through the earlier described driven movement of the central rod  16  first moves from the horizontal position to a vertical position and subsequently returns again to the horizontal position. It should be noted here that panel part  2 ″ is pivotally connected to frame  4  in a way that is not further shown. Its pivot axis lies near the end of the horizontal panel and is essentially parallel with the dividing line between panel  2 ′ and panel  2 ″. 
         [0041]    Because in  FIGS. 2 ,  3  and  4  central rod  16  has the same position in the figures with the same letter indication, it is clear that the described movements take place simultaneously. 
         [0042]    In moving the visual screen/television device from the operating position to the storage position all movements that have been described above take place in the reverse direction. A possible exception to this is formed by the movement of holder  8  with visual screen/television device  3  downwards along the bracket  9 . This movement is caused by gravity. Because the angle that bracket  9  in the storage position makes with the horizontal plane is smaller than 30 degrees, this angle can become so small (in possible embodiments of the invention also 0°) that the influence of the gravity is insufficient to move holder  8  and visual screen/television device  3  along bracket  9 . To prevent that holder  8  and visual screen/television device  3  get stuck prematurely, a cable roller  26  including a spring is mounted to frame  4 , next to electromotor  5 , see  FIG. 2   i . From cable roller  26  second pulling cable  27  runs along guide  6 , over a roller at the bottom side of bracket  9  and is connected to the bottom side of holder  8 . Through the tension of the spring in cable role  26  a pulling force downward is executed on holder  8  and through this on visual screen/television device  3 , so that these always will return to the desired storage position, also when holder and visual screen/television device make a very small angle with the horizontal plane in this position. 
         [0043]    Although an embodiment of the invention is shown, it will be clear that many variants to this are possible, e.g. by a slightly different embodiment of the rod systems. The same or similar movements can be achieved in equivalent ways without deviating of the attached claims.
