One way clutch hinge for a base of a tablet computer
View Patent ↗An information handling system includes a base, a hinge area, and a clutch device. The hinge area is in physical communication with the base, and includes a curved portion. The curved portion is to be placed in physical communication with a tablet computer when the tablet computer is in a first open position, and the hinge area is to hold the tablet computer in the first open position. The clutch device is located within the hinge area, and includes rollers, a shaft, and a clutch housing. A weight of the tablet computer is to exert a first torque on the clutch device. The rollers are to lock the clutch device in response to the first torque, and the clutch device locks in response to the rollers being placed in physical communication with both the shaft and the clutch housing.

2. The information handling system of claim 1 , wherein the clutch device further includes a friction element, wherein in response to the hinge area and the clutch device being rotated from the first open position to a second open position, the rollers to lock within the clutch device and the friction elements to provide a second torque to resist rotation of the hinge area from the first open position to the second open position.
3. The information handling system of claim 2 , wherein in response to the hinge area and the clutch device being rotated from the second open position to the first open position, the rollers to release within the clutch device to cause the rollers to no longer be in physical communication with the clutch housing, and the clutch device to provide a third torque to aid the rotation of the hinge area from the second open position to the first open position.
4. The information handling system of claim 3 , wherein the second torque is in an opposite direction as the third torque.
5. The information handling system of claim 1 , wherein clutch device further includes a roller cage, the roller cage to control movement of the rollers within the clutch device.
6. The information handling system of claim 1 , wherein clutch device further includes a spring in physical communication with the shaft, the spring to force the rollers in physical communication with the shaft and with the clutch housing.
7. An information handling system comprising:
a base including a keyboard;
a hinge area in physical communication with the base, the hinge area including a curved portion, the curved portion to be placed in physical communication with a tablet computer when the tablet computer is in a first open position, and the hinge area to hold the tablet computer in the first open position; and
a clutch device located within the hinge area, the clutch device including rollers, a shaft, and a clutch housing, a weight of the tablet computer to exert a first torque on the clutch device in a direction away from the keyboard of the base, the rollers to lock the clutch device in response to the first torque, wherein the clutch device locks in response to the rollers being placed in physical communication with both the shaft and the clutch housing.
8. The information handling system of claim 7 , wherein the clutch device further includes a friction element, wherein in response to the hinge area and the clutch device being rotated from the first open position to a second open position, the rollers to lock within the clutch device and the friction elements to provide a second torque to resist rotation of the hinge area from the first open position to the second open position.
9. The information handling system of claim 8 , wherein in response to the hinge area and the clutch device being rotated from the second open position to the first open position, the rollers to release within the clutch device to cause the rollers to no longer be in physical communication with the clutch housing, and the clutch device to provide a third torque to aid the rotation of the hinge area from the second open position to the first open position.
10. The information handling system of claim 9 , wherein the second torque is greater than the third torque.
11. The information handling system of claim 7 , wherein clutch device further includes a roller cage, the roller cage to control movement of the rollers within the clutch device.
12. The information handling system of claim 7 , wherein clutch device further includes a spring in physical communication with the shaft, the spring to torque rotation of the roller cage to place the rollers in physical communication with the shaft and with the clutch housing.
13. An information handling system comprising:
a component to move from a first position to a second position; and
a clutch device coupled to the component, the clutch device including rollers, a shaft, and a clutch housing, a weight of the component to exert a first torque on the clutch device, the rollers to lock the clutch device in response to the first torque, wherein the clutch device locks in response to the rollers being placed in physical communication with both the shaft and the clutch housing.
14. The information handling system of claim 13 , wherein the clutch device further includes a friction element and a gear, wherein in response to the component being moved from the first position to the second position and the gear rotating in a first direction, the rollers to lock within the clutch device and the friction elements to provide a second torque to resist rotation of the gear in the first direction and the movement of the component from the first position to the second position.
15. The information handling system of claim 14 , wherein in response to the component moving from the second position to the first position and the clutch device being rotated in a second direction, the rollers to release within the clutch device to cause the rollers to no longer be in physical communication with the clutch housing, and the clutch device to provide a third torque to aid the movement of the component from the second position to the first position.
16. The information handling system of claim 15 , wherein the second torque is greater than the third torque.
17. The information handling system of claim 13 , wherein clutch device further includes a roller cage, the roller cage to control movement of the rollers within the clutch device.
18. The information handling system of claim 13 , wherein clutch device further includes a spring in physical communication with the shaft, the spring to place the rollers in physical communication with the shaft and with the clutch housing.
