Assist mechanism for information handling system
A mechanism for servicing a sled installed in a server includes a grip bar, and a four-bar linkage connected to the grip bar. The four-bar linkage has a first position that engages the sled to a chassis of the server, and a second position that disengages the sled from the chassis of the server. Movement of the grip bar moves the four-bar linkage from the first position to the second position, thus disengaging the sled from the chassis and allowing the sled to be removed from the chassis for service.
1. A mechanism for servicing a sled installed in a server, the mechanism comprising:
a grab bar; and
a four-bar linkage connected to the grab bar, the four-bar linkage having a slider bar pivotally connected to an arm connected to the grab bar, the four-bar linkage having a first position that engages a latch bar to a chassis of the server, and the four-bar linkage having a second position that disengages the sled from the chassis of the server, and a slot having a curved lifting region along which the slider bar slides;
wherein a movement of the grab bar moves the slider bar and pushes the latch bar into the lifting region and moves the four-bar linkage from the first position to the second position, thus disengaging the latch bar and the sled from the chassis and allowing the sled to be removed from the chassis for service.
2. The mechanism of claim 1 , wherein the four-bar linkage comprises a thumb latch.
3. The mechanism of claim 1 , further comprising a side wall.
4. The mechanism of claim 1 , further comprising a side wall having the slot.
5. The mechanism of claim 1 , further comprising an opposed latch bar that is opposed to the latch bar.
6. The mechanism of claim 1 , wherein the four-bar linkage comprises an arm that extends from the grab bar.
7. The mechanism of claim 1 , further comprising a backing.
8. The mechanism of claim 1 , wherein the latch bar has a dog-leg.
9. A method for servicing a sled installed in a server, the method comprising:
sweeping a grab bar from a stowed position to a deployed position; and
moving a four-bar linkage comprising a slider bar pivotally connected to an arm connected to the grab bar from a first position to a second position by sliding the slider bar in a slot with a curved lifting region, the first position engaging a latch bar the sled to a chassis of the server in the stowed position of the grab bar, and a movement of the grab bar to the second position moves the slider bar and pushes the latch bar into the lifting region and disengages the latch bar from the chassis of the server in the deployed position of the grab bar;
wherein the sweeping of the grab bar moves the four-bar linkage from the first position to the second position and disengages the latch bar from the chassis and allows the sled to be removed from the chassis.
10. The method of claim 9 , further comprising a thumb latch.
11. The method of claim 9 , further comprising a side wall.
12. The method of claim 11 , further comprising a side wall having the lifting region of the slot.
13. The method of claim 9 , further comprising removing the sled from the chassis of the server.
14. The method of claim 9 , further comprising inserting the sled into the chassis of the server.
15. The method of claim 9 , further comprising receiving an electrical power.
16. The method of claim 9 , further comprising lifting the grab bar.
17. An information handling system, comprising:
a hardware processor;
a memory device;
a sled;
an assist mechanism integrated with the sled, the assist mechanism including a grab bar with an arm pivotally connected to a slider bar of a four-bar linkage, the four-bar linkage having a first position engaging a latch bar of the sled to a chassis of the information handling system in a stowed position of the grab bar, and the four-bar linkage having a second position disengaging the sled from the chassis of the server in a deployed position of the grab bar; and
a slot with a curved lifting region along which the slider bar slides;
wherein a movement of the grab bar moves the slider bar and pushes the latch bar into the lifting region and moves the four-bar linkage from the stowed position to the deployed position, thus disengaging the latch bar and the sled from the chassis and allowing the sled to be removed from the chassis for a service.
18. The information handling system of claim 17 , wherein the assist mechanism comprises a thumb latch bar.
19. The information handling system of claim 17 , wherein the assist mechanism comprises a side wall.
20. The information handling system of claim 17 , further comprising a power supply.
