Television stand having a tilt mechanism

Claim 2

A television stand comprising: a base stand, a movable member pivotably supported on said base stand for supporting a television, a tilt mechanism including a cam surface formed by one of said movable member and said base stand and a pressurized movable device abutting said cam surface for positioning of said movable member, and said can surface is formed so that the bias force of said movable device against said cam surface corresponds to a balanced force with respect to the moment of rotation due to the weight of said television.

Claim 3

A television stand according to claim 1 wherein the movable device is energized by a spring bridged between said movable device and a shaft which pivotably mounts the movable member on the base stand.

Claim 4

A television stad according to claim 1 wherein said cam surface is defined by said movable member and the movable base includes a guide slit in which the movable device is slidably inserted.

Claim 5

A television stand according to claim 1 wherein said cam surface includes stopper portions for stopping the movement of said movable device.

Claim 6

A television stand for supporting a television monitor at a desired position, said television stand comprising: a base stand, a movable member for supporting said television monitor, tilt means for fixing said movable member with respect to said base stand, said tilt means including a cam surface defined by said movable member, a movable device slidably mounted in guide means defined by said base stand, a shaft mounted on said base stand and said movable member being pivotably mounted on said shaft, and a spring suspended between said movable device and said shaft for energizing said movable device so that said movable device abuts said cam surface and the position of abutment to the cam surface by said movable device changes according to the tilt of the movable member, said cam surface being shaped so that the energized force of the spring is balanced with a revolution moment of said movable member due to the weight of the television monitor, and said moveable member thereby is held at a desired position.

Claim 7

A television stand for supporting a television monitor at a desired position, said television stand comprising: a base stand, a movable member for supporting said television monitor, tilt means for fixing said movable member with respect to said base stand, said tilt means including a cam surface defined by said movable member, a movable device slidably mounted in guide means defined by said base stand, a shaft mounted on said base stand and said movable member being pivotably mounted on said shaft, and a spring suspended between said movable device and said shaft for energizing said movable device so that said movable device abuts said cam surface and the position of abutment to the cam surface by said movable device changes according to the tilt of the movable member, said cam surface being shaped so that the energized force of the spring is balanced with a revolution moment of said movable member due to the weight of the television monitor, and said moveable member thereby is held at a desired position.

Claim 8

A television stand according to claim 5 wherein a guide slit forms said guide means and a rotor mounted on said movable device rotatably abuts against said cam surface.

Claim 9

A television stand according to claim 5 wherein a guide rail as a guide means is fixed on said base stand.

Claim 10

A television stand according to claim 5 wherein stopper members are formed at both ends of the cam surface for stopping the movement of said movable device.

Claim 11

A television stand according to claim 5 wherein the base stand consists of a fixed disk, a rotary plate inserted into this fixed disk rotatively in a horizontal direction, and a portion which secures the movable member attached to said rotary plate.

Claim 12

A television stand comprising: a base stand, a movable member, a television monitor mounted on said movable member, tilt means for fixing said movable member with respect to said base stand, said tilt means including a cam surface defined by said movable member, said movable device slidably mounted in guide means defined by said base stand, a shaft mounted on said base stand and said movable member being pivotably mounted on said shaft, and a spring suspended between said movable device and said shaft for energizing said movable device so that said movable device abuts said cam surface and the position of abutment to the cam surface by said movable device changes according to the tilt of the movable member, said cam surface being shaped so that the energized force of the spring is balanced with a revolution moment of said movable member due to the weight of the television monitor, and said movable member is thereby held at a desired position.

Claim 13

A television stand comprising: a base stand, a movable member, a television monitor mounted on said movable member, tilt means for fixing said movable member with respect to said base stand, said tilt means including a cam surface defined by said movable member, said movable device slidably mounted in guide means defined by said base stand, a shaft mounted on said base stand and said movable member being pivotably mounted on said shaft, and a spring suspended between said movable device and said shaft for energizing said movable device so that said movable device abuts said cam surface and the position of abutment to the cam surface by said movable device changes according to the tilt of the movable member, said cam surface being shaped so that the energized force of the spring is balanced with a revolution moment of said movable member due to the weight of the television monitor, and said movable member is thereby held at a desired position.

Claim 14

A television stand according to claim 10 wherein a guide slit forms said guide means and a rotor mounted on said movable device rotatably abuts against said cam surface.

Claim 15

A television stand according to claim 10 wherein said base stand is composed of a fixed disk, a rotation disk inlaid in said fixed disk horizontal-rotatably, and a member secures the movable member attached to the revolution disk.
