Abstract

A flat panel television adjustable wall mount having a wall mounting plate, a center rack assembly attached to the flat panel television, an extendable frame, and a telescopic adjustment mechanism attached to first and second struts. The telescopic adjustment mechanism includes a telescopic guided slider and a telescopic drive. The upper end of the first strut is pivotally connected to the wall mounting plate while its lower end is rotationally installed at the lower end of the telescopic guided slider. The lower rolling mechanism end of the second strut is set on the wall mounting plate while its upper end is rotationally connected to the center rack assembly. The telescopic drive activates the first strut and the second strut, allowing the center rack assembly with the flat panel television to extend out or retract back to the wall mounting plate to achieve an optimum viewing distance.

Claims

1. An adjustable wall mount for a flat panel television, comprising:

a. a wall mounting plate for securing the wall mount to a wall;

b. a center rack assembly attached to the flat panel television, said center rack assembly comprises;

i. a center frame rotationally connected to said upper end of said second strut; and

ii. a main shaft connected to said center frame vertically;

iii. a center post rotationally connected to said main shaft and positioned axially to the lower end of said center frame; and

v. a telescopic drive rack rotationally connected to said main shaft and rotates in sync with said center post;

c. an extendable frame having a first strut and a second strut which are pivotally connected together; and

d. a telescopic adjustment mechanism with one end attached to said wall mounting plate and the other end attached to said center rack assembly, said telescopic adjustment mechanism comprises;

i. a telescopic guided slider which travels up and down said center rack assembly; and

ii. a telescopic drive attached to said center rack assembly and drives said telescopic guided slider up and down relative to the said center rack assembly;

wherein said center frame is connected on an upper end of said main shaft, said telescopic guided slider connecting to said main shaft and glides up and down relative to said center frame, said telescopic drive is connected to a lower end of said center frame, and the flat panel television is adapted to connect to said main shaft;

wherein said telescopic guided slider is positioned within said center post, said telescopic drive is positioned on said center post, and said telescopic drive rack and said telescopic guided slider both glide in synchronization along said main shaft; and

wherein an upper end of said first strut is pivotally connected to said wall mounting plate and a lower end of said first strut is rotationally installed at a lower end of said telescopic guided slider, and a lower end of the said second strut rolls along said wall mounting plate while an upper end of said second strut is rotationally connected to said center rack assembly.

2. The adjustable wall mount for a flat panel television of claim 1, wherein said telescopic drive rack comprises:

i. a telescopic rack; and

ii. a telescopic pinion corresponding to said telescopic rack;

wherein said telescopic drive rack is driven as a result of the combination of said telescopic rack and said telescopic pinion gliding on said main shaft.

3. The adjustable wall mount for a flat panel television of claim 1 further comprising:

e. a pan mechanism comprises;

i. a panning slot plate;

ii. a pan drive assembly; and

iii. a pan mount that is rotationally connected to said main shaft;

wherein said pan drive assembly and said pan mount are rotatable in sync with said center post, said panning slot plate is driven by said pan drive assembly to glide relative to said pan drive assembly, allowing said pan drive assembly to rotate relative to said main shaft, and the flat panel television is adapted to connect to said pan mount.

4. The adjustable wall mount for a flat panel television of claim 3, wherein said center frame comprises:

i. a positioning convex post with a convex element pointing to said panning slot plate;

wherein said pan drive assembly comprises;
