Tool-less retention system for an electronic device
View Patent ↗The invention broadly contemplates a tool-less retention system that appropriately distributes load via various distributed load points to prevent damage caused to a computer by heavy adapter cards during shipping. At least one embodiment of the invention includes a tool-less retention system with a balanced distributed load point positioned to contact and transfer force to the computer chassis at a region with great resistance to warping.
1. An apparatus comprising:
a chassis;
a tool-less adapter card retainer having a distributed load point configured to engage a predetermined region of the chassis having a support member disposed thereon, the predetermined region of the chassis configured to absorb a dropping force transferred by the distributed load point without being damaged;
wherein a top surface of the support member contacts a bottom surface of the tool-less adapter card retainer and a protrusion of the distributed load point contacts a side surface of the support member.
2. The apparatus according to claim 1 , wherein the support member is configured to reversibly engage the distributed load point.
3. The apparatus according to claim 1 , wherein the predetermined region comprises a bottom-central region of the chassis.
4. The apparatus according to claim 1 , wherein the predetermined region has a higher second moment of area than a rail of the chassis.
5. The apparatus according to claim 1 , wherein the apparatus further comprises a heavy graphics card contained within the tool-less adapter card retainer.
6. The apparatus according to claim 1 , wherein the apparatus further comprises a plurality of heavy graphics cards contained within the tool-less adapter card retainer.
7. The apparatus according to claim 1 , wherein the dropping force is at least 40 G.
8. The apparatus according to claim 1 , wherein the dropping force is at least 50 G.
9. An apparatus comprising:
a processor housed within a chassis of the apparatus;
a tool-less adapter card retainer having adapter cards therein and housed within the chassis, the tool-less adapter card retainer having a distributed load point configured to impart force F D to a support member disposed on a predetermined region of the chassis configured to absorb force F D without being damaged;
wherein a top surface of the support member contacts a bottom surface of the tool-less adapter card retainer and a protrusion of the distributed load point contacts a side surface of the support member.
10. The apparatus according to claim 9 , wherein the support member is configured to reversibly engage the distributed load point.
11. The apparatus according to claim 9 , wherein the predetermined region comprises a bottom-central region of the chassis.
12. The apparatus according to claim 9 , wherein the apparatus further comprises a heavy graphics card contained within the tool-less adapter card retainer.
13. The apparatus according to claim 9 , wherein the apparatus further comprises a plurality of heavy graphics cards contained within the tool-less adapter card retainer.
14. The apparatus according to claim 9 , wherein force F D is at least 30 G.
15. The apparatus according to claim 9 , wherein force F D is at least 40 G.
16. The apparatus according to claim 9 , wherein force F D is at least 50 G.
17. An apparatus comprising:
a chassis;
at least one processor housed with the chassis; and
a support member;
wherein the support member is disposed on a predetermined region of the chassis configured to absorb a dropping force transferred by a distributed load point of a tool-less adapter card retainer without being damaged;
wherein a top surface of the support member contacts a bottom surface of the tool-less adapter card retainer and a protrusion of the distributed load point contacts a side surface of the support member.
18. The apparatus according to claim 17 , wherein the side cover is a removable cover covering a side portion of the apparatus that when removed exposes internal components of said apparatus and allows said tool-less adapter card retainer to be swung open about a hinge portion.
