Abstract

In a television stand secured tiltably to a base stand and provided with a television fixedly put on it, the tilt of the movable member is stopped by the energized force to a movable device by the abutment to the cam surface formed at the movable member or the base stand.

Claims

1. 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 said movable member and a pressurized movable device abutting said cam surface for positioning of said movable member, and

a guide rail mounted on said base stand, said movable device being slidably mounted on said guide rail,

said cam surface being 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.

2. A television stand as in claim 1, wherein stopper portions are formed at two ends of said cam surface for stopping movement of said movable device.

3. A television stand as in claim 1, wherein said movable device includes a roller mounted on said guide rail.

4. A television stand comprising:

a base stand,

a movable member pivotably supported on said base stand for supporting a television, and

a tilt mechanism including a cam surface formed by said movable member and a pressurized movable device abutting said cam surface for positioning of said movable member, and

spring means for securing said movable member to said movable device,

said cam surface being 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.

5. A television stand as in claim 4, wherein stopper portions are formed at two ends of said cam surface for stopping movement of said movable device.

6. 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 said movable member and a pressurized movable device abutting said cam surface for positioning of said movable member,

spring means for securing said movable member to said movable device, and

a guide rail mounted on said base stand, said movable device being slidably mounted on said guide rail,

said cam surface being formed so that the bias force of said movable device against said cam surfce corresponds to a balanced force with respect to the moment of rotation due to the weight of said television.

7. A television stand as in claim 6, wherein stopper portions are formed at two ends of said cam surface for stopping movement of said movable device.

8. A television stand as in claim 6, wherein said movable device includes a roller mounted on said guide rail.
