Preferably, a single cable is employed to form an all-in-one connection (video, audio L/R, voltage source, etc.) to increase the ease in which the video display unit 30 may be manipulated independently of the video player device 10. Additional audio/ video sockets 60, 62 a and 62 b define the electrical interface of the video display unit 30 adapted to be operably connected to the electrical interface of the video player device 10 and communicate electrical signals therebetween to provide independent connection to any video player device.
As shown in FIGS. 7 and 11, a lower end of the display casing 44 is pivotally mounted to the hinge portions 36 a and 36 b of the base member 32 through a continuous resistance device. The pivotal connection allows the video display panel 42 to pivot at least 180° relative to the base member 32. A latch mechanism includes the cantilevered release lever 26 provided with the locking tab 27 to engage the locking recess 35 in the stand portion 34 of the base member 32, thus providing releasable connection between the video player device 10 and the video display unit 30.
As best shown in FIGS. 2 and 11, when the video display unit 30 is attached to the video player device 10, opposite end portions of the stand portion 34 of the base member 32 are disposed in the support slots 25 a and 25 b formed in the extensions 24 a and 24 b of the casing 12 of the video player device 10. In the installed position, the locking tab 27 of the cantilevered release lever 26 positively engages the locking recess 35 in the stand portion 34 of the base member 32 as illustrated in FIGS. 12 and 13, thus firmly securing the video display unit 30 to the video player device 10.
A user can easily disengage the video display unit 30 from the video player device 10 by simply depressing the ribbed button surface 28 of the release lever 26 by his finger (as the button surface 28 is accessible through the through opening 38 in the stand portion 34) to bend the release lever 26 away from the stand portion 34 of the base member 32 into the casing 12 of the video player device 10. This action disengages the locking tab 27 from the locking recess 35 in the stand portion 34 of the base member 32. At the same time, the user should lift the stand portion 34 upward to slide the base member 32 out of the support slots 25 a and 25 b in the casing 12 of the video player device 10.
If the user intends to leave the video display unit 30 attached to the video player device 10, the video display panel 42 can be pivoted downward so that the video display panel 42 is oriented downward adjacent to the top panel 12 _Tof the video player device 10 in the stowed position (shown in FIG. 2), or the video display panel 42 can be pivoted upward so that the video display panel 42 projects outwardly from the top panel 12 _Tof the video player device 10 in the deployed position (shown in FIG. 1)wherein the display screen 46 is viewable by the user of the video player assembly.
The video display unit 30 may be electronically connected to the video player device 10 by any method known in the art, such as by a single cable bundle connected through a single audio/video port in each of the video display unit 30 and the video player device 10. Such electronic connections are well within the knowledge of one of ordinary skill in the art and need not be elaborated further. The audio/video signal is thus transmitted to the video display unit 30. The video display unit 30 includes conventional circuitry and components to display the video images and broadcast audio. The video display panel 42 includes associated audio and video controls 52 on the display casing 44 to adjust the display screen 46 and speaker volume. Such video display panel 42 may include LCD display screen. However it is to be understood that any display device capable of displaying vide signals may be employed. An independent power supply may be employed to power the video display panel 42 or a battery compartment may be provided.
In operation, a user simply inserts the opposite end portions of the stand portion 34 of the base member 32 into the support slots 25 a and 25 b formed in the extensions 24 a and 24 b of the casing 12 of the video player device 10, as illustrated in FIG. 14. The stand portion 34 is dimensioned to fit in the support slots 25 a and 25 b formed in the extensions 24 a and 24 b of the casing 12. The front surface of the stand portion 34 substantially conforms to a corresponding portion of the rear panel 12 _Rof the player casing 12 such that the two surfaces rest substantially flush against one another when connected. The locking tab 27 of the cantilevered release lever 26 projects outward from the rear panel 12 _Rof the casing 12 such that as the base member 32 is inserted into the support slots 25 a and 25 b, the cantilevered release lever 26 is forced backwards until the locking tab 27 engages the corresponding locking recess 35. When the stand portion 34 of the base member 32 is inserted sufficiently into the support slots 25 a and 25 b, the cantilevered release lever 26 springs back due to the resiliency thereof and the locking tab 27 engages the locking recess 35. The overall arrangement provides a snug snap fit releasable connection between the video display unit 30 and the video player device 10.
The video display panel 42 may then be adjusted to pivot between the stowed position whereby the display panel 42 rests substantially flush against the top panel 12 _Tof the video player device 10, and the deployed position suitable to be viewed by the user by manipulating the pivotal connection between the lower end of the video display panel 42 and the base member 32. When the video display panel 42 is stored flush against the top panel 12 _Tof the video player device 10, the arrangement of the present invention provides a compact complete portable video player assembly.
As indicated above, the rotatable (pivotal) connection between the base member 32 and the video display panel 42 of the video display unit 30 includes the continuous resistance device that requires a threshold force to rotate the video display panel 42 relative to the base member 32, thus allowing the video display panel 42 to be infinitely adjustable between various angular positions between the stored position and an open position. Preferably, the video display panel 42 may be rotated in excess of 180°.
To release the video display unit 30 from the separate video player device 10, the user simply inserts a finger within the through opening 38 in the stand portion 34 of the base member 32, depresses the ribbed button surface 28 of the release lever 26 by his finger to bend the release lever 26 away from the stand portion 34 of the base member 32 into the casing 12 of the video player device 10 and force the locking tab 27 out of the corresponding locking recess 35 in the stand portion 34 of the base member 32. The video display unit 30 may then be simply pulled out of the support slots 25 a and 25 b in the casing 12 and thereby detached from the video player device 10. The overall arrangement provides a detachable yet secure connection between the video display unit 30 and the video player device 10 to positively retain the video display unit 30 to the video player device 10.
Moreover, the present invention allows the video display unit 30 to be removed from the video player device 10 and independently supported on any substantially flat surface. As illustrated in FIG. 15, the base member 32 is adjusted relative to the video display panel 42 to an angular position allowing the base member 32 to independently support the video display panel 42 on a substantially flat surface 70. In other words, when the base member 32 is rotated backward, away from the viewing surface of the video display panel 42, the base member 32 may function as an independent stand for the video display panel 42 of the video display unit 30, as shown in FIG. 15.
While the present invention is described in relation to the DVD player, the invention is equally suited for use with other electronic video player devices, such as CVD and VCR players, and other similar processing units producing an electronic video signal. Although the materials of construction are not described, they may include a variety of compositions consistent with the function of the invention.
