Abstract

An improved desk for a computer system capable of maximizing the usable surface of the upper surface of the desk by selectively hiding the monitor under the desk, which includes a desk body internally provided with a monitor, the monitor being lifted or lowered; a monitor frame to which the monitor is engaged; a support member for fixing the monitor frame to the desk body; and a driving member for lifting/lowering the monitor frame, so that the monitor can be lifted onto the desk body or lowered under the table in cooperation with the driving member.

Claims

1. A computer desk which comprises:

a computer monitor;

a desk body comprising an upper surface and an interior sized and shaped to receive the computer monitor therein, an opening being formed from the interior through the upper surface;

support means in the interior of the desk body for movably supporting the computer monitor, the support means being rotatable relative to the desk body for extending and retracting the monitor through the opening, the desk body further comprising a pair of axis holes on opposite sides of the support means, the support means comprising supporting members releasably spring biased into the holes to facilitate rotation of the support means;

driving means for lifting/lowering the support means for lifting/lowering the monitor through the opening, whereby in an extended position the monitor is extended through the opening, and in a retracted position the monitor is completely retracted within the interior of the desk body with a viewing portion of the monitor facing the opening; and

a transparent window in the plane of the upper surface of the desk body covering the opening when the monitor is in the retracted position, wherein the monitor is visible through the transparent window with the monitor in the retracted position, the transparent window rotating as the monitor is extended through the opening for enabling visibility of the monitor in the extended position.

2. The computer desk in accordance with claim 1, wherein the desk body comprises a drawer-like keyboard support panel movable between an extended position in which the keyboard support panel is extended from the desk body and a retracted position in which the keyboard support panel is retracted into the desk body;

and wherein the driving means further comprises means for driving the keyboard support panel to the extended position while lifting the support means to the extended position of the monitor and for driving the keyboard support panel to the retracted position while lowering the support means to the retracted position of the monitor.

6. A computer desk which comprises:

a desk body comprising an upper surface and an interior sized and shaped to receive a computer monitor therein, an opening being formed from the interior through the upper surface;

support means in the interior of the desk body for movably supporting a computer monitor, a fixed end of the support means being pivotally mounted to the desk body, the other end of the support means being a free end; and

driving means for lifting/lowering the free end of the support means for lifting/lowering the monitor through the opening, whereby in an extended position the monitor is extended through the opening, and in a retracted position the monitor is completely retracted within the interior of the desk body, the driving means comprising a reversible motor and a driving member being driven by the reversible motor for lifting/lowering the support means.

3. The computer desk according to claim 12 wherein the driving means comprises:

a reversible motor; and

a driving member being driven by the reversible motor for lifting/lowering the support means.

4. The computer desk according to claim 3, wherein the driving member comprises:

a sector arm attached to the support means, the sector arm being drivingly connected to the reversible motor.

5. The computer desk according to claim 3 wherein the driving means further comprises a lever having one end attached to the driving member and a second end attached to the support means.

7. The computer desk in accordance with claim 6, wherein the desk body comprises a drawer-like keyboard support panel movable between an extended position in which the keyboard support panel is extended from the desk body and a retracted position in which the keyboard support panel is retracted into the desk body;

and wherein the driving means further comprises means for moving the keyboard support panel to the extended position while lifting the support means to the extended position of the monitor and for moving the keyboard support panel to the retracted position while lowering the support means to the retracted position of the monitor.

8. The computer desk according to claim 7 wherein the keyboard support panel moving means comprises:

a keyboard support panel driving member driven by the reversible motor for extending and retracing the keyboard support panel concurrently with the lifting and lowering of the monitor.

9. The computer desk according to claim 8 wherein the driving member comprises:

a sector arm attached to the support means, the sector arm being drivingly connected to the reversible motor, and wherein the keyboard support panel driving member comprises;

a wire extending between the sector arm and the keyboard support panel.

10. The computer desk according to claim 8 wherein the keyboard support panel driving member further comprises:

a guide rod for slidably guiding the keyboard support panel; and

spring means for applying an outward biasing force on the keyboard support panel.

11. The computer desk in accordance with claim 6 wherein the desk body comprises a pair of axis holes on opposite sides of the fixed end of the support means, and wherein the support means comprises supporting members releasably spring biased into the holes to facilitate rotation of the support means relative to the desk body.

12. The computer desk according to claim 6 wherein the driving member comprises:

a sector arm attached to the support means, the sector arm being drivingly connected to the reversible motor.

13. The computer desk according to claim 6 wherein the driving means further comprises a lever having one end attached to the driving member and a second end attached to the support means.

14. A computer desk which comprises:

a desk body comprising an upper surface and an interior sized and shaped to receive a computer monitor therein, an opening being formed from the interior through the upper surface;

support means in the interior of the desk body for movably supporting a computer monitor; and

driving means for lifting/lowering the support means for lifting/lowering the monitor through the opening, whereby in an extended position the monitor is extended through the opening, and in a retracted position the monitor is completely retracted within the interior of the desk body, the driving means comprising a reversible motor, and i) a sector arm attached to the support means, the sector arm being drivingly connected to the reversible motor, or ii) a driving member rotated by the reversible motor and a lever, the lever having one end attached to the driving member and a second end attached to the support means.

15. A computer desk which comprises:

a desk body comprising an upper surface and an interior sized and shaped to receive a computer monitor therein, an opening being formed from the interior through the upper surface;

support means in the interior of the desk body for movably supporting a computer monitor;

driving means for lifting/lowering the support means for lifting/lowering the monitor through the opening, whereby in an extended position the monitor is extended through the opening, and in a retracted position the monitor is completely retracted within the interior of the desk body;

a drawer-like, keyboard support panel movable between an extended position in which the keyboard support panel is extended from the desk body and a retracted position in which the keyboard support panel is retracted into the desk body; and

the driving means further comprises means for concurrently moving the keyboard support panel to the extended position while lifting the support means to the extended position of the monitor and for moving the keyboard support panel to the retracted position while lowering the support means to the retracted position of the monitor.

16. The computer desk according to claim 15 wherein the driving means comprises:

a reversible motor;
