Abstract

A lifting mechanism for selectively lifting a computer monitor, and particularly a flat screen computer monitor, from below a desktop to a position on the desktop includes a stationary member including a linear slide mechanism, a vertically slideable support member sized and dimensioned to receive a computer display monitor and coupled to the linear slide mechanism, and a latch member. The vertically slideable support member is further coupled to a stored mechanical energy source such as a constant force compression spring, and is retained in a position below the desk by application of the latch member. When the latch member is released, the stored mechanical energy source causes the vertically slideable support member to move upward along the linear slide, through an aperture in a desk, until the computer monitor rests on a plane equivalent with the desktop. A deceleration mechanism is preferably also provided on the vertically slideable member, the declaration mechanism limiting the speed of the vertically slideable member as it approaches the end of the linear slide mechanism, thereby limiting the possibility of derailment.

Claims

1. A computer monitor lifting device for moving a computer monitor between a retracted and an extended position relative to a work surface, the computer monitor lifting device comprising:

a stationary support member coupled beneath a work surface;

a computer monitor support moveably coupled to the stationary support member, the computer monitor support including a fixed top horizontal member and a fixed lower horizontal member spaced below the top horizontal member, the top and bottom horizontal members being sized and dimensioned to at least mostly fill an aperture in the work surface, and spaced vertically at a distance selected to allow a computer monitor to be received on the monitor support between them;

a computer monitor coupled to the monitor support between the top and bottom horizontal members; and

a lifting device coupled to the monitor support, the lifting device providing an upward lifting force directed against the weight of the monitor and the monitor support when the monitor support is in a retracted position.

2. The computer monitor lifting device as defined in claim 1, wherein the lifting device comprises a mechanical energy storage device coupled between the stationary support and the equipment support.

3. The computer monitor lifting device as defined in claim 2, wherein the energy storage device is a constant force coil spring.

4. The computer monitor lifting device as defined in claim 1, wherein the computer monitor support is moveably coupled to the stationary support through a linear slide mechanism.

5. The computer monitor lifting device as defined in claim 4, further comprising a latching mechanism coupled between the computer monitor support and the work surface to counteract the lifting mechanism and to retain the computer monitor beneath the work surface when in the retracted position.

6. The computer monitor lifting device as defined in claim 1, further comprising an enclosure for enclosing the computer monitor when the computer monitor is in the retracted position.

7. The computer monitor lifting device as defined in claim 6, wherein the enclosure is lockable.

8. The computer monitor lifting device as defined in claim 1, wherein the lifting mechanism comprises a constant force coil spring.

9. The computer monitor lifting device as defined in claim 8, wherein the constant force coil spring is retained in tension in a retracted position and is released to lift the computer monitor to an extended position.

10. The computer monitor lifting device as defined in claim 9, further comprising a latching mechanism that retains the constant force coil spring in tension when latched.

11. A computer monitor lifting device for moving a computer monitor between a retracted and an extended position relative to a work surface, the computer monitor lifting device comprising:

a stationary support member coupled beneath a work surface;

a computer monitor support slidably coupled to the stationary support member, the computer monitor support including a top horizontal member and a lower horizontal member spaced below the top horizontal member, the top and bottom horizontal members being sized and dimensioned to at least partially fill an aperture in the work surface, and spaced vertically and fixed relative to one another at a distance selected to allow a computer monitor to be received on the monitor support between them;

a computer monitor coupled to the monitor support between the top and bottom horizontal members;

a lifting device coupled to the monitor support, the lifting device providing an upward lifting force directed against the weight of the monitor and the monitor support when the monitor support is in a retracted position;

a latching mechanism for latching the computer monitor support to the stationary support; and

a latch release mechanism for releasing the latching mechanism, wherein in the retracted position the latching mechanism maintains the computer monitor support beneath the work surface with the top horizontal member located within the aperture in the work surface, and when the latching mechanism is released, the lifting mechanism drives the computer monitor support upward to the extended position, with the lower horizontal member located proximate or within the aperture in the work surface, and the computer monitor and the top horizontal member located above the work surface.

12. The computer monitor lifting device as defined in claim 11, wherein the lifting device is a mechanical energy storage device held in tension while the computer monitor is in the retracted position.

13. The computer monitor lifting device as defined in claim 12, wherein the latching mechanism couples the computer monitor support to the stationary support and retains the mechanical energy storage device in tension.

14. The computer monitor lifting device as defined in claim 12, wherein the mechanical energy storage device comprises at least one of a constant force torsional coil spring, a compression spring, an extension spring, or a gas spring.

15. The computer monitor lifting device as defined in claim 11, wherein the computer monitor support is coupled to the stationary support with a linear ball bearing slide.

16. The computer monitor lifting device as defined in claim 11, further comprising a deceleration device coupled to the monitor support and activatable by a stop member coupled to the stationary support, wherein during upward movement of the monitor support the deceleration device contacts the stop member to decelerate the monitor support as the monitor support approaches the extended position.
