DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now in detail to the drawings, the reference numeral 10 denotes generally a video monitor mounting system constructed in accordance with and embodying the present invention. The mounting system may be employed in any of a number of applications such as, for example, within a head restraint 12 of a passenger seat, within a seat back of a cabin seat or within an overhead console.
FIG. 1 illustrates a mounting system installation within a rear face 14 of the head restraint 12 and, more particularly, within a hollowed out rectangular socket 16 which is formed in the head restraint 12.
Pursuant to the invention, the mounting system 10 includes a mounting tray 18 having a generally rectangular anchor plate 20, a peripheral top wall 22, a bottom wall 24 and a pair of parallel opposed sidewalls 26, 28 all of uniform height. The anchor plate 20 and the peripheral walls 22, 24, 26 and 28 define a mounting tray cavity.
The depth of the socket 16 is such that the mounting tray 18 will be accommodated within the socket, with the peripheral walls 22, 24, 26 and 28 lying substantially flush with rear face 14 of the head restraint or slightly recessed within the socket 16.
The mounting tray 18 includes a plurality of openings 30 formed in the anchor plate 20 and through each of which a screw 32 is inserted and driven into the head restraint 12. The mounting tray may be secured within a socket 16 or any other support surface by conventional securement devices other than the screws 32, such as adhesives, rivets, clips, etc.
It should be noted that the anchor plate 20 includes a passageway 34 for control and video signal wiring (not shown) which is threaded through the vehicle seat back and head restraint 12 or, in ceiling mount installations, behind a vehicle headliner.
The mounting tray 18 includes a pair of noncircular apertures 36, each formed in a rearwardly offset portion 38 of the anchor plate 20. As shown in FIG. 6, each aperture 36 includes a cylindrical collar 40 which projects forwardly from the offset portion 38. At the end of the collar 40, a pair of upper and lower flanges 42, 44 are provided, leaving, in a horizontal direction, an enlarged keyway passage having arcuate ends 46, 48. The upper and lower flanges 42, 44 each include diametrically opposed concentric arcuate cut outs 43, 45.
A video display assembly 50 includes a video display panel 52, e.g. an LCD panel, housed in a generally parallelepiped or cuboid cabinet 54. The cabinet 54 is, in turn, carried in a shell casing 56. The shell casing 56 includes a rectangular back wall 58, a top peripheral wall 60, a bottom peripheral wall 62, and a pair of opposed side peripheral walls 64, 66. The back wall 58 and the peripheral walls 60, 62, 64 and 66 define a shell casing cavity.
The cabinet 54 is mounted for rotation relative to the shell casing 56 about a pivot axis 55 which extends through the side peripheral walls 64, 66. The forward edge of the peripheral walls 60, 62, 64, 66 may include a transverse bead or flange 68.
The back wall 58 of the shell casing 56 includes a passageway 70 for wiring, and a pair of fastener apertures 72. With reference now to FIG. 5, wherein the fastener apertures 72 are shown in enlarged detail, it should be noted that each aperture 72 is generally circular except, however, for upper and lower flanges 74, 76 having diametrically opposed concentric arc portions 78, 80. The diameter spanning the arc portions 78, 80 is less than the diameter spanning the arcuate cut outs 43, 45 of the flanges 42, 44.
Pursuant to the invention, a twist fastener 82 is inserted through and seats in each of the fastener apertures 72. As will be noted from an observation of FIGS. 2, 3 and 4, each twist fastener 82 includes an axial body 84 having a diameter less than the diameter of the arc portions 78, 80 and of the arcuate cut outs 43, 45, formed in the flanges 42, 44.
Each fastener 82 also includes, adjacent the end of the body 84, a pair of diametrically opposed radial tabs 86 having curved ends. The resulting noncircular axial fastener profile is dimensioned to pass through the fastener aperture 72 and the keyway passage of the aperture 36, when tabs 86 are horizontally oriented.
It should also be noted that each twist fastener 82 includes a pair of diametrically opposed radial projection retention bosses 88 which extend from the body 84 in vertical directions, as viewed in FIG. 2. Each retention boss 88 terminates with an axial abutment ledge 90.
The distance between the cylindrically curved outer surfaces of the opposed retention bosses 88 is slightly larger than the diametrical distance between the arc portions 78, 80 of the flanges 74, 76 respectively, yet less than the diametrical distance between the arcuate cut outs 43, 45. Because of this negative clearance, after the bosses are registered with the arc portions 78, 80, each twist fastener 82 must be forced through the aperture 72. When the abutment ledge 90 of each boss 88 passes rearwardly of the flanges 76, 78, the ledge 90 functions to prevent inadvertent removal of the twist fasteners 82 from the shell casing 56.
To facilitate rotation without hand tools, each twist fastener 82 includes an enlarged domed cap 92 having a slot 94, which may be engaged by a coin for rotating the fastener 82.
A simplified mounting procedure in accordance with the invention thus entails:

    
    
        a) securing the mounting tray in the socket,
        b) positioning the twist fasteners 82 within their respective fastener apertures 72 (if the video display assembly 50 does not have the twist fasteners 82 prepositioned),
        c) connecting the wiring to the display panel,
        d) nesting the shell casing 56 within the mounting tray 18 after assuring that the twist fasteners are properly oriented (with the radial tabs 82 on a horizontal axis),
        e) positioning the radial tabs axially behind the flanges 42, 44, and
        f) rotating each twist fastener 82 one quarter turn (90°) with a coin, screwdriver or other implement, to a position wherein the radial tabs 86 are registered with the upper and lower flanges 42, 44.
    
    


The video display assembly is thus securely mounted. Thereafter, the video display panel cabinet 54 is rotated, from the mounting position illustrated in FIG. 1, to a position wherein it is nested within the shell casing 56, with the video display panel 52 exposed for viewing. In a seat back or head restraint application, the viewing position may be further adjusted by rotating the cabinet 54 about the axis 55 to a suitable viewing angle as illustrated in FIG. 8.
In a roof mount, installation, the cabinet 54 is stowed in its nested horizontal position, within the shell casing 56 and is thereafter rotated downwardly to a viewing position for rear seat passengers. Such viewing position may be substantially as illustrated in the FIG. 1 orientation, with the understanding, however, that the back wall 58 of the shell casing is substantially horizontal, rather than vertical.
It should also be appreciated that the video monitor mounting system herein has been described in an exemplary manner only. Various changes are readily apparent to those of skill in the art.
Thus it will be appreciated that there is provided a video monitor mounting system of the general character described which achieves the various aspects, features and considerations of the present invention and which is well suited to meet the conditions of practical usage.
As various possible further embodiments might be made of the present invention and as various changes might be made in the illustrative embodiment set forth herein without departing from the spirit of the invention, it is to be understood that all matter herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
