Abstract
Abstract Disclosed is a monitor foot for supporting a video monitor which allows adjustment of the extension of the foot. By adjusting the monitor foot, the angle of presentation of the screen of the video monitor is adjusted. The monitor foot of the present invention is adjusted using a spring loaded ratchet means which, when engaged with the foot, prevents the sliding of the foot.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
236 words
An apparatus for adjusting the angle of presentation of a screen on the front of a video monitor, the video monitor having a lower edge, comprising: a slidable foot, having a top, a bottom, a left side, a right side, an inside, and an outside for supporting the video monitor at an angle of presentation; rail means for securing said slidable foot formed along said left side and said right side of said slidable foot; guide means formed on the video monitor for receiving said rail means so that said slidable foot slides to extend said bottom of said slidable foot below the lower edge of the video monitor; ratchet means for engaging said slidable foot to prevent movement of said slidable foot when engaged, said ratchet means including a series of teeth formed on said slidable foot on said inside parallel with said left side, and an elongate member with a pawl for engaging one of said series of teeth mounted on the video monitor, said elongate member being mounted so that a distal end of said elongate member protrudes slightly from said video monitor and a proximal end is adjacent said series of teeth, and a ratchet spring mounted on the video monitor against said proximal end of said elongate member so that said pawl tends to engage said series of teeth and so that said pawl is disengaged by depressing said distal end.
Claim 2
Independent Claim
236 words
An apparatus for adjusting the angle of presentation of a screen on the front of a video monitor, the video monitor having a lower edge, comprising: a slidable foot, having a top, a bottom, a left side, a right side, an inside, and an outside for supporting the video monitor at an angle of presentation; rail means for securing said slidable foot formed along said left side and said right side of said slidable foot; guide means formed on the video monitor for receiving said rail means so that said slidable foot slides to extend said bottom of said slidable foot below the lower edge of the video monitor; ratchet means for engaging said slidable foot to prevent movement of said slidable foot when engaged, said ratchet means including a series of teeth formed on said slidable foot on said inside parallel with said left side, and an elongate member with a pawl for engaging one of said series of teeth mounted on the video monitor, said elongate member being mounted so that a distal end of said elongate member protrudes slightly from said video monitor and a proximal end is adjacent said series of teeth, and a ratchet spring mounted on the video monitor against said proximal end of said elongate member so that said pawl tends to engage said series of teeth and so that said pawl is disengaged by depressing said distal end.
Claim 3
Dependent Claim
44 words
The apparatus of claim 1, further including: a slide spring connected at one end to said slidable foot and said video monitor so that said slidable foot tends to extend below said lower edge of the video monitor when said ratchet means is disengaged.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1, wherein: said guide means is formed on the back of the video monitor and so that the extension of said bottom of said slidable foot below the lower edge of said video monitor causes the angle of presentation of the screen on the front of the video monitor to vary.
