  5. Detailed description of the invention.

  The general principle of the invention is therefore based on a display system comprising a removable sleeve. Thus, when the system goes from a position where the display device is hooked to a pose on a horizontal plane, the user can easily insert the display device into the sheath which ensures the stability of the screen. Conversely, when the system passes from a pose on a horizontal plane to a hanging or suspended position, the user can easily remove the display device from its sleeve and hang it. This architecture makes it possible to offer the user the flexibility in the choice of his installation.

  Figure 1 schematically illustrates a front view of a display system 1 laid on a horizontal plane according to a preferred embodiment of the invention.

  The display system 1 comprises: a display device 10 comprising a flat screen 101, a box 107 and one or more loudspeakers 102 on the front; and a hollow sleeve 11 for accommodating the display device.

  The flat screen 101 is, for example, an LCD screen or a plasma type screen.

  The speaker (s) 102 are positioned below the screen.

  The display device 10 is inserted into the sheath 11 which keeps the display device in a substantially vertical position (that is to say with a screen whose front plane is at an angle less than or equal to 11 with the vertical). and more generally in a position of comfort allowing a good visualization of a spectator located in front of the screen.

  The sheath comprises a base 111 and walls 110. The base 111 comprises a substantially flat bottom face e intended to rest on a substantially horizontal ground (that is to say making an angle less than or equal to 11 with a horizontal plane) and an upper face substantially parallel to the lower face (that is to say the two faces forming at least partly planes forming between them an angle less than or equal to 110). The inner and outer faces of the walls 110 are substantially vertical, the walls 110 forming a recess and being intended to hold the display device when the latter is inserted into the sheath.

  FIG. 2 shows a rear view of the screen 1 and illustrates, in particular, rear parts 103 and 104 associated with the display device 10 and which comprise, in particular, connectors intended to connect the device 10 to a power supply and / or to audio / video inputs / outputs.

  Figures 3 and 4 illustrate the display device 1 in a three-quarter view respectively rear and front by highlighting the base 111 of the sleeve 11.

  The width of the base 111 resting on the ground is, for example, equal to 170 mm for a screen 101 having a diagonal of 26. More generally, the parts of the base 111 situated respectively in front of and behind the walls 110 each have a depth preferably greater than 4 cm and even more preferably greater than 6 cm Thus, the stability of the display device 10 is ensured when it is placed on a substantially horizontal plane.

  Figures 10 and 11 illustrate the display system 1 according to a side view resting on a 1000 respectively horizontal plane and inclined at an angle y relative to a horizontal plane.

  Preferably, the device 1 remains stable when the display device 1 rests on a substantially horizontal plane with an inclination less than or equal to 11 (y is less than or equal to 11) towards the front or the rear of the device 1.

  In other words, the depths d and of parts of the base 111 located respectively in front of and behind the walls 110 and resting on the ground are such that the center of gravity, G, 1001 of the device 1 is preferably between two vertical planes 1002 and 1003 which pass respectively through the ends A and B corresponding to the front and rear edges of the base 111 when the device rests on a substantially horizontal plane with an inclination less than or equal to 11 towards the front or rear of the device 1. In general, the planes 1005 and 1006 passing through the center of gravity G and corresponding respectively to vertical planes when the value of inclination of the ground relative to the horizontal is maximum (or preferably 11) define the minimum values dm and m of the depths d and of (the part of the base 111 resting on the ground must extend beyond the planes 1005 and 1006).

  FIG. 5 shows a view of the display system 1 when the removable screen 10 is separated from the sheath 11.

  The walls 110 comprise: a recess 112 on the front panel allowing the insertion of the speaker (s) 102; recesses 113 and 114 on the rear face enabling insertion of the rear portions 103 and 104, respectively; and lateral and facial uprights 116 and 117 and a rear upright 115 making it possible to hold the screen 10.

  The recesses 112 to 114 have a shape adapted to the element of the device 10 they receive. The walls are substantially vertical in the hollow portion of the sleeve when the system is placed on a substantially horizontal plane, the display device inserted between the walls.

  Preferably, they are precisely adjusted to this shape (the dimensions of each recess are substantially equal to those of the element they receive). Preferably, the recesses and the corresponding elements they receive have a shape that allows easy insertion of these elements (for example vertical edges and / or width of each recess or the corresponding element decreasing downwards). Preferably, the outer surfaces of the walls 110 and the display device 10 are contiguous; in other words, the cabinet of the display device 10 comprises recesses 105 and 106 of a depth preferably greater than or equal to (and even more preferably equal to) the thickness of the walls 110, so that the walls 110 outcrop the outer surface of the box of the device 10. Thus, the outer face of the walls 110 and the outer surface of the device 10 are contiguous and tangent and there is therefore no roughness between the box and the walls 110, which allows in particular to improve the aesthetics of the system and to reduce the size.

  The sheath is preferably made of plastic and is, for example, obtained by plastic injection in one piece. Thus, the support is relatively economical and simple to manufacture. In addition, the invention offers a potential for personalization by the diversity of colors and finishes.

  According to a variant of the invention, the display device does not have a recess 105 or 106 and the sheath simply comprises the necessary recesses for the parts of the display device requiring a free part in the sheath (speakers, inputs / outputs, displays, remote control sensor, power supply). In this case, preferably, the thickness of the walls of the sheath is small (typically less than or equal to 3 mm) so as to limit the roughness between the sheath and the display device when the latter is placed on a horizontal plane.

  According to an alternative embodiment of the invention, the base 111 is ballasted (and comprises for example a solid part made of metal), which makes it possible to improve the stability of the system 1 and to reduce the bulk of the sheath 11.

  According to another embodiment of the invention, the sheath comprises additional fixing means which make it possible to improve the retention of the display device in the sheath. Thus, according to this variant, the vertical walls are, for example, equipped with screws intended to be screwed on the device 10 (which comprises a female screwing part) or clips which snap onto the device 10 (which then comprises a hollow allowing the reception of the protrusion of the clips). Preferably these additional fixing means are located at the rear of the sheath.

  In general, the number of plastic parts is limited (for example equal to one) and the fixing between the sheath and the display device is limited (for example equal to one, two or three) and preferably zero.

  The recesses 614 and 615 have a shape adapted to the element of the device 60 they receive. Preferably, they are precisely adjusted to this shape (the dimensions of each recess are substantially equal to those of the element they receive). Preferably, the recesses and the corresponding elements they receive have a shape that allows easy insertion of these elements (for example vertical edges and / or width of each recess or the corresponding element decreasing downwards). Preferably, the outer surfaces of the walls 611 and the display device 60 are contiguous and, advantageously, tangential; in other words, the cabinet of the display device 60 comprises recesses 605 to 607 of a depth preferably greater than or equal to (and even more preferably equal to) the thickness of the walls 611, so that the walls 611 outcrop the outer surface of the box of the device 60. Thus, there is no roughness between the box and the walls 611.

  The sheath is preferably made of plastic and is, for example, obtained by plastic injection in one piece.

  The depth d1 of the base 610 resting on the ground is, for example, equal to 170 mm for a screen 10 of 26. More generally, the parts of the base 610 situated respectively in front of and behind the walls 611 each have a depth d5. and preferably 5 greater than 4 cm and even more preferably greater than 6 cm Thus, the stability of the display device 60 is ensured when it is placed on a substantially horizontal plane Preferably, the display system 6 is posed on a plane inclined at 11 forwards or backwards must remain stable, in other words, the depths d5 and 5 are such that the center of gravity, G, 1001, of the system 6 is preferentially understood between two vertical planes which pass respectively through the ends corresponding to the front and rear edges of the base 610 when the device rests on a substantially horizontal plane with an inclination less than or equal to 11 v at the front or back of the device 1.

  The hollow 616 in the base 610 has a depth greater than or equal to the height d3 of the recesses 605 to 607. The height d3 is for example equal to 50 mm and more generally between 30 and 60 mm for dedicated display systems 6 TVs with screen diagonals between 20 "to 37".

  Figures 8 and 9 schematically illustrate a front view and a top view of a display system 8 according to an alternative embodiment of the invention.

  The display system 8 comprises in front: a display device 80 comprising a flat screen 800, a box 807 and two side acoustic speakers 802 and 803; and a hollow sleeve 81 for accommodating the display device 80.

  The flat screen 80 is, for example, an LCD screen or a plasma type screen.

  When the display system 8 is placed on a substantially horizontal plane, the display device 80 is inserted into the sheath 81 which keeps the display device in a substantially vertical position and more generally in a position of comfort allowing good visualization. of a spectator located in front of the screen.

  The sheath 81 comprises a base 810 whose substantially flat bottom face is intended to rest on a substantially horizontal floor and substantially vertical walls 811 for holding the display device when the latter is inserted into the sheath.

  The walls 811 comprise: - recesses on the rear face allow insertion of the rear parts (power supply, inputs / outputs) of the display device; and - lateral and facial uprights 813.

  Preferably, the outer surfaces of the walls 811 and the display device 80 are contiguous and tangent; in other words, the cabinet of the display device 80 comprises a recess 801 of a depth preferably greater than or equal to (and even more preferably equal to) the thickness of the walls 811, so that the walls 811 are flush with the surface outer casing of the device 80. Thus, there is no roughness between the cabinet and the walls 811.

  The sheath is preferably made of plastic and is, for example, obtained by plastic injection in one piece.

  The width d1 of the base 810 resting on the ground is, for example, equal to 170 mm for a screen 80 of 26 "More generally, the parts of the base 810 situated respectively in front of and behind the walls 811 each have a depth d5 preferably, greater than 4 cm and even more preferably greater than 6 cm, thus the stability of the display device 80 is ensured when it is placed on a substantially horizontal plane.

  The trough 813 in the base 810 has a depth d4 greater than or equal to the height d3 of the recess 801.

  Figures 12 and 13 schematically illustrate a front view and a top view of a display system 12 according to an alternative embodiment of the invention.

  The display system 12 comprises: a display device 80 similar to the device illustrated with reference to FIG. 8 and bearing the same references; and a hollow sheath 1201 for accommodating the display device 80.

  The sheath 1201 comprises a base 1203 intended to rest on a substantially horizontal floor and a hollow portion 1201 whose internal walls are substantially vertical and whose depth d4 is greater than or equal to the height d3 of the recess 801. The hollow portion 1201 is intended to to maintain the display device 80 when the latter is inserted into the sheath. The sides of the sheath 1201 are oblique, which allows in particular to increase its rigidity. This also allows to increase its weight and thus improve the stability of the device by lowering the center of gravity of the assembly.

  The display device 12 comprises a recess 801 of a depth preferably greater than or equal to (and even more preferably equal to) the thickness of the upper part of the sheath 1201, so that the outer surface of the sheath 1201 is flush with the surface of the display device 80. Thus, the sheath 1201 and the device 80 are contiguous, and there is no roughness between these two elements.

  According to one variant, the sheath has an external surface whose upper part is substantially vertical and which gradually fades or compensates. Thus, the sheath and the device are contiguous and tangent.

  Figure 14 schematically illustrates a side view of a display system 14 according to an alternative embodiment of the invention.

  The display system 12 comprises: a display device 10 similar to the device illustrated with reference to FIG. 1 and bearing the same references; and a hollow sleeve 1400 for accommodating the display device 10.

  The sheath 1400 comprises a base 1402 intended to rest on a substantially horizontal floor and a hollow portion 1401 whose internal walls are slightly inclined rearwardly preferably by an angle less than or equal to 3 and typically between 1.5 and 3 . The depth of the hollow portion 1401 is greater than or equal to the height of the recess of the device 10. The hollow portion 1401 is intended to keep the display device 10 in a slightly inclined position towards the rear to facilitate the comfort of the viewer and / or reduce the depth of the base located in front of the device 10, when the latter is inserted into the sheath. The display device 10 comprises recesses 105 and 106 of a depth preferably greater than or equal to (and even more preferably equal to) the thickness of the upper sleeve portion, so that the walls 110 are flush with the outer surface of the sleeve 1400. Thus, the sheath 1400 and the device 10 are contiguous and tangent, and there is no roughness between these two elements.

  Figures 15 to 17 schematically illustrate a front view, a side view and a section AA in a side view of a sheath according to an alternative embodiment of the invention.

  The display system according to Figures 15 to 17 comprises: a display device 10 similar to the device illustrated with reference to Figure 1 (and not shown in Figures 15 to 17) and a hollow sleeve 15 to accommodate the display device 10.

  The display device 10 is inserted into the sheath 15 which keeps the display device in a substantially vertical position (that is to say with a screen whose front plane is at an angle less than or equal to 11 with the vertical). and more generally in a position of comfort allowing a good visualization of a spectator located in front of the screen.

  The sheath comprises a base 1506, walls 110 and a wall bracket 1501. The base 1506 is attached to the wall bracket which includes a substantially flat side face for resting on a substantially vertical wall (i.e. less than or equal to 11 with a vertical plane). According to alternative embodiments, the walls can be leaned forward to allow positioning in height, the screen being itself leaning forward. According to another variant, the walls are slightly bent backwards to allow positioning close to the ground, the screen being itself leaning backwards.

  The wall support comprises means for attaching to a wall (for example, holes allowing the passage of screws 1502 to 1505, the wall support being screwed to the wall or slipping between the wall and the screw heads (holes allowing the heads to pass screw with slot on the upper part allowing the body of the screws but by their head) .The inner and outer faces of the walls 1500 are substantially vertical, the walls 1500 forming a hollow and being intended to maintain the display device 10 when the latter is inserted into the sheath The wall thickness is preferably less than or equal to 3 mm The thickness of the wall support is preferably between 3 and 7 mm The base is preferably but not necessarily hollow.

  Thus, the display device is relatively flexible in use since a user can easily suspend the screen to a wall (embodiment with sheath with wall bracket) and / or place it on a substantially horizontal plane (depending on the modes realization of the sleeve intended to rest on a floor). In addition, the display device can easily be transported with or without a sleeve (the latter can be left in place or otherwise moved).

  Of course, the invention is not limited to the embodiments described above.

  In particular, the skilled person can implement a sheath of any material other than plastic (eg, metal).

  Moreover, the invention does not limit the fixing of display devices with LCD type screens but concerns all devices with flat screens, which in particular have an overall depth less than or equal to 100 mm, the depth of the part inserting into the corresponding sleeve being preferably less than or equal to 50 mm. In particular, the invention relates to a monitor-type flat panel display system with a relatively small depth (for example equal to 12 mm or even 8 mm). Thus, for a 15 "screen, the depth of the corresponding sheath in front of and behind the vertical walls is, for example, between 40 and 45 mm This is particularly advantageous for display systems dedicated to laptops since transport is facilitated (small footprint).

  The invention also relates to display systems whose sheath has walls inclined rearwardly relative to a plane perpendicular to its base, preferably of a value less than or equal to 3 (for example a value between 1,5 and 3). According to such an embodiment, the depth of the base in front of the walls can be reduced (indeed, in this case, the center of gravity of the system back) to satisfy the condition of stability of the system resting on a substantially horizontal floor and preferentially inclined at an angle less than or equal to a horizontal plane.

  The invention relates to systems with adjacent contiguous and tangent display and sheath. It also relates to systems whose display device and associated sheath are not tangent (as shown in Figure 12) or not contiguous. Indeed, the invention also relates to systems with a display device without recess in its lower part. According to this variant, the display device is not specific and the sleeve is adapted to receive such a device.
