Abstract

Apparatuses, tables, and method of making the apparatuses and tables are disclosed for stowing and expanding a desk device. An exemplary apparatus, in one embodiment, includes a frame, a first surface slidably received by the frame in a horizontal plane between and including a stowed position and an expanded position, and a second surface slidably received by the frame between and including a stowed position and an expanded position.

Claims (46)

1. An apparatus comprising:

a frame;

a first surface slidably received by the frame in a horizontal plane between and including a stowed position and an expanded position;

a second surface slidably received by the frame between and including a stowed position and an expanded position;

a first motor configured to move the second surface in a vertical direction; and

a switch configured to cause:

the first motor to move the second surface vertically upward to the expanded position responsive to the switch being in a first position; and

the first motor to move the second surface vertically downward to the stowed position responsive to the switch being in a second position.

2. The apparatus of claim 1 , wherein the second surface is positioned under the first surface in the stowed position.

3. The apparatus of claim 2 , wherein the second surface is in a vertical position matching a vertical position of the first surface in the expanded position.

4. The apparatus of claim 1 , further comprising a device configured to block the second surface from moving in a vertical direction until the first surface is at a predefined location relative to the frame.

5. The apparatus of claim 1 , wherein the device is further configured to deactivate the first motor from moving the second surface, when the first surface is blocking the second surface.

6. The apparatus of claim 1 , further comprising a sensor configured to:

sense a first condition;

generate a first signal responsive to sensing the first condition; and

send the first signal to the first motor,

wherein the first signal is configured to cause the first motor to move the second surface vertically upward to the expanded position or vertically downward to the stowed position.

7. The apparatus of claim 6 , further comprising a second motor configured to move the first surface horizontally responsive to the first signal, the switch being in the first position, or the switch being in the second position.

8. A table comprising:

legs;

a frame supported by the legs;

a first leaf slidably received by the frame in a horizontal plane between and including a stowed position and an expanded position;

a second leaf slidably received by the frame between and including a stowed position and an expanded position;

a first motor configured to move the second leaf in a vertical direction; and

a switch configured to cause:

the first motor to move the second leaf vertically upward to the expanded position responsive to the switch being in a first position; and

the first motor to move the second leaf vertically downward to the stowed position responsive to the switch being in a second position.

9. The table of claim 8 , wherein the second leaf is positioned under the first leaf in the stowed position.

10. The table of claim 9 , wherein the second leaf is in a vertical position matching a vertical position of the first leaf in the expanded position.

11. The table of claim 8 , further comprising a device configured to block the second leaf from moving in a vertical direction until the first leaf is at a predefined location relative to the frame.

12. The table of claim 8 , wherein the device is further configured to deactivate the first motor from moving the second leaf, when the first leaf is blocking the second leaf.

13. The table of claim 8 , further comprising a sensor configured to:

sense a first condition;

generate a first signal responsive to sensing the first condition; and

send the first signal to the first motor,

wherein the first signal is configured to cause the first motor to move the second leaf vertically upward to the expanded position or vertically downward to the stowed position.

14. The table of claim 13 , further comprising a second motor configured to move the first leaf horizontally responsive to the first signal, the switch being in the first position, or the switch being in the second position.

15. A method of making a stowable table, the method comprising:

providing a table frame;

slidably receiving a first leaf horizontally within the table frame;

slidably receiving a second leaf vertically within the table frame,

wherein the first leaf is located above the second leaf when the stowable table is in a stowed condition,

wherein the first leaf and the second leaf are horizontally aligned when the stowable table is in an expanded condition;

providing one or more motors configured to move the first leaf or the second leaf;

providing a switch configured to provide control signals to the one or more motors; and

providing a sensor configured to provide control signals to the one or more motors.
