Design for automatic positioning of power supply module handle
View Patent ↗A system for securing a module within a chassis includes a rotatable handle located on the module. The rotatable handle includes a notch and a latch. The chassis includes a cam and guide rail. In embodiments of the invention, the interaction of the notch and the latch on the handle with the cam in the chassis operate to automatically rotate the handle from an open position to a closed position when the module is inserted into the chassis by pushing on a bezel of the module. Embodiments of the invention move the module into a seated position within the chassis when the handle is rotated from an open position to a closed position.
1. A system for securing a module within a chassis comprising:
a rotatable handle, located on the module, that includes a notch and a latch;
at least one feature, located on the chassis, that includes a cam and a guide rail, wherein the cam interacts with the notch to automatically rotate the handle from an open position to a closed position as the module is inserted into the chassis, and cam interacts with the notch and the latch to secure the module within the chassis with the cam being disposed between the notch and the latch when the handle is in the closed position.
2. The system of claim 1 , wherein the module is a power supply.
3. The system of claim 1 , wherein the cam and the guide rail are comprised of sheet metal.
4. The system of claim 1 , wherein the chassis further includes at least one hold down feature, which reduces vertical movement of the module within the chassis.
5. The system of claim 4 , wherein the hold down feature is a tab.
6. The system of claim 5 , wherein the tab is comprised of sheet metal.
7. The system of claim 4 , wherein the module includes an upper surface, the upper surface including first and second edges where the first edge is generally opposite the second edge and wherein the at least one hold down feature comprises two features, with one feature located adjacent to the first edge of the upper surface of the module and the other located adjacent to the second edge of the upper surface of the module.
8. The system of claim 1 , wherein the handle and the feature act to prevent the module overshooting during insertion into the chassis.
9. The system of claim 1 , wherein the latch is capable of interacting with the cam to move the module into a seated position within the chassis when the handle is rotated from an open position to a closed position.
10. A system for securing a module within a chassis comprising:
a rotatable handle, located on the module, that includes a notch and a latch;
at least one feature, located on the chassis, that includes a cam and a guide rail, wherein the latch interacts with the cam to move the module into a seated position within the chassis as the handle is rotated from an open position to a closed position, wherein the notch and the latch interact with the cam to secure the module within the chassis with the cam being disposed between the notch and the latch when the handle is in the closed position.
11. The system of claim 10 , wherein the module is a power supply.
12. The system of claim 10 , wherein the cam and the guide rail are comprised of sheet metal.
13. The system of claim 10 , wherein the chassis further includes at least one hold down feature, which reduces vertical movement of the module within the chassis.
14. The system of claim 13 , wherein the hold down feature is a tab.
15. The system of claim 14 , wherein the tab is comprised of sheet metal.
16. The system of claim 13 , wherein the module includes an upper surface, the upper surface including first and second edges where the first edge is generally opposite the second edge and wherein the at least one hold down feature comprises two features, with one feature located adjacent to the first edge of the upper surface of the module and the other located adjacent to the second edge of the upper surface of the module.
17. The system of claim 10 , wherein the handle and the feature act to prevent the module overshooting during insertion into the chassis.
18. The system of claim 10 , wherein the cam is capable of interacting with the notch to automatically rotate the handle from an open position to a closed position when the module is inserted into the chassis by pushing a bezel of the module.
