Abstract

An information handling system includes a top portion, a heatsink, a base portion, and a foot portion. The top portion transitions between a closed position and an open position. The heatsink includes a main portion and an extension portion. The main portion of the heatsink is located within the base portion, and extension portion of the heatsink extends beyond a surface of the base portion. The foot portion transitions between a retracted position and an extended position. The foot portion is in the retracted position and the extension portion of the heatsink is surrounded by the foot portion when the top portion is in the closed position. The foot portion is in the extended position and the extension portion of the heatsink is viewable when the top portion is in the open position.

First claim

What is claimed is:

1 . An information handling system comprising:
a top portion to transition between a closed position and an open position; a heatsink including a main portion and an extension portion; a base portion coupled to the top portion, wherein the main portion of the heatsink is located within the base portion, and the extension portion of the heatsink extends beyond a surface of the base portion; and a foot portion coupled to the top portion, the foot portion to transition between a retracted position and an extended position, wherein the foot portion is in the retracted position and the extension portion of the heatsink is surrounded by the foot portion when the top portion is in the closed position, and the foot portion is in the extended position and the extension portion of the heatsink is viewable when the top portion is in the open position.

2 . The information handling system of claim 1 , further comprising: a hinge system in physical communication with the top portion, with the base portion, and with the foot portion, wherein a force is exerted on the hinge system during the transition of the top portion from the closed position and the open position.

3 . The information handling system of claim 2 , wherein the hinge system transfers the force to the foot portion, wherein the force causes the foot portion to transition from the retracted position to the extension position.

4 . The information handling system of claim 1 , further comprising: a foot in physical communication with the foot portion, wherein the foot exerts a force on the foot portion to transition the foot portion to the extended position.

5 . The information handling system of claim 1 , wherein the base portion is lifted as the foot portion transitions to the extended position.

6 . The information handling system of claim 1 , wherein an amount of airflow within in the heatsink increases when the foot portion is in the extended position.

7 . The information handling system of claim 1 , wherein heat dissipation is increased by the extension portion of the heatsink when the extension portion is visible.

8 . The information handling system of claim 1 , wherein a top surface of the foot portion is in physical communication with a bottom surface of the base portion when the foot portion is in retracted position, and the top surface is not in physical communciatoin with the bottom surface when the foot portion is in the extended position.

9 . An information handling system comprising:
a top portion to transition between a closed position and an open position; a heatsink including a main portion and an extension portion; a base portion coupled to the top portion, wherein the main portion of the heatsink is located within the base portion, and the extension portion of the heatsink extends beyond a surface of the base portion; and a foot portion coupled to the top portion, the foot portion to transition between a retracted position and an extended position, wherein the foot portion is in the retracted position and the extension portion of the heatsink is surrounded by the foot portion when the top portion is in the closed position, wherein the foot portion is in the extended position and the extension portion of the heatsink is viewable when the top portion is in the open position, wherein an amount of airflow within the heatsink increases when the foot portion is in the extended position, and wherein heat dissipation is increased by the extension portion of the heatsink when the extension portion is visible.

10 . The information handling system of claim 9 , further comprising: a hinge system in physical communication with the top portion, with the base portion, and with the foot portion, wherein a force is exerted on the hinge system during the transition of the top portion from the closed position and the open position.

11 . The information handling system of claim 10 , wherein the hinge system transfers the force to the foot portion, wherein the force causes the foot portion to transition from the retracted position to the extension position.

12 . The information handling system of claim 10 , wherein the hinge system includes a linkage to change a rotational force from the top portion into a linear force on the foot portion.

13 . The information handling system of claim 10 , wherein the hinge system includes a hinge to rotate at a same rate as the top portion.

14 . The information handling system of claim 9 , further comprising: a foot in physical communication with the foot portion, wherein the foot exerts a force on the foot portion to transition the foot portion to the extended position.

15 . The information handling system of claim 9 , wherein the base portion is lifted as the foot portion transitions to the extended position.

16 . The information handling system of claim 9 , wherein a top surface of the foot portion is in physical communication with a bottom surface of the base portion when the foot portion is in retracted position, and the top surface is not in physical communciatoin with the bottom surface when the foot portion is in the extended position.

17 . An information handling system comprising:
a top portion to transition between a closed position and an open position; a heatsink including a main portion and an extension portion; a base portion coupled to the top portion, wherein the main portion of the heatsink is located within the base portion, and the extension portion of the heatsink extends beyond a surface of the base portion; a foot portion coupled to the top portion, the foot portion to transition between a retracted position and an extended position, wherein the foot portion is in the retracted position and the extension portion of the heatsink is surrounded by the foot portion when the top portion is in the closed position, and the foot portion is in the extended position and the extension portion of the heatsink is viewable when the top portion is in the open position; a foot in physical communication with the foot portion, wherein the foot exerts a force on the foot portion to transition the foot portion to the extended position; and a hinge system in physical communication with the top portion, with the base portion, and with the foot, wherein a first force is exerted on the hinge system during the transition of the top portion from the closed position and the open position and the hinge system exerts a second force on the foot portion via the foot as the top portion the transitions from the closed position to the open position.

18 . The information handling system of claim 17 , wherein an amount of airflow within in the heatsink increases when the foot portion is in the extended position.

19 . The information handling system of claim 17 , wherein a top surface of the foot portion is in physical communication with a bottom surface of the base portion when the foot portion is in retracted position, and the top surface is not in physical communciatoin with the bottom surface when the foot portion is in the extended position.

20 . The information handling system of claim 17 , wherein the base portion is lifted as the foot portion transitions to the extended position.
