Device sled extension limit latch
Technology is provided for a device sled with an extension limit latch. The device sled includes a sled chassis having a bottom wall and a sidewall extending between a front sled portion and a rear sled portion. The extension limit latch includes a latch arm having a proximal end portion pivotably coupled to the sled chassis proximate the rear sled portion. A latch barb extends from the latch arm and a distal end portion of the arm includes an actuation tab. The latch arm is pivotable between a latched position where the latch barb is positioned to engage a latch feature of a cubby chassis, thereby preventing removal of the sled chassis from the cubby chassis, and an unlatched position where the latch barb is disengaged from the latch feature of the cubby chassis.

the latch handle further comprises a distal end portion comprising a handle lock comprising:
a housing;
a lock plunger; and
a resilient member positioned between the housing and the lock plunger.
7. The device sled of claim 6 , wherein:
the lock plunger extends from the housing when the handle lock is in a locked position; and
the lock plunger is retracted into the housing when the handle lock is in an unlocked position.
8. The device sled of claim 7 , wherein:
the resilient member urges the lock plunger to engage with the aperture; and
the handle lock is in the locked position when the latch handle is in the latched position, the locked position of the handle lock locking the distal end portion of the latch handle to the sidewall based on the engagement of the lock plunger with the aperture.
9. The device sled of claim 7 , wherein:
the handle lock further comprises a button positioned in the housing and coupled to a cam;
the button is configured to move the lock plunger through the cam when the button is depressed by a user; and
the handle lock is in the unlocked position when the latch handle is in the unlatched position, the unlocked position of the handle lock unlocking the distal end portion of the latch handle from the sidewall based on movement of the lock plunger through the cam in response to the user depressing the button.
10. A system comprising:
a cubby chassis comprising a bottom panel, the bottom panel comprising a front edge; and
a device sled comprising:
a sled chassis extending between a front sled portion and a rear sled portion and having a bottom wall and a sidewall, the sidewall comprising a first detent hole and a second detent hole; and
a latch handle comprising a proximal end portion movably coupled to the sidewall proximate the front sled portion, the proximal end portion comprising:
a latch pawl extended from the proximal end portion;
a slot with a detent spring mounted in the slot, the slot positioned for engaging the first detent hole and the second detent hole; and
an ejector pawl extended from the proximal end portion in a direction that opposes the latch pawl, wherein the latch handle is movable between:
a latched position where the latch pawl is positioned to engage a latch feature formed in the bottom panel of the cubby chassis and the detent spring engages with the first detent hole, and
an unlatched position where the ejector pawl works against the front edge of the bottom panel of the cubby chassis as the latch handle is moved from the latched position to the unlatched position disengaging the latch pawl from the latch feature of the cubby chassis and engaging the detent spring with the second detent hole.
11. The system of claim 10 , wherein the detent spring comprises a leaf spring with a centrally positioned protrusion adapted to engage the first detent hole and the second detent hole.
12. The system of claim 10 , wherein:
the sidewall comprises a stop pin;
the proximal end portion of the latch handle further comprises a limit slot; and
movably coupling the proximal end portion to the sidewall proximate the front sled portion comprises positioning the limit slot over the stop pin.
13. The system of claim 12 , wherein positioning the limit slot over the stop pin limits movement of the latch handle towards the latched position and limits movement of the latch handle towards the unlatched position.
14. A device platform comprising:
a cubby chassis comprising:
a bottom panel comprising a front edge; and
a chassis partition defining a sled position within the cubby chassis, the sled position having a latch feature formed in the bottom panel; and
a device sled comprising:
a sled chassis extending between a front sled portion and a rear sled portion and having a bottom wall and a sidewall, the sidewall comprising a first detent hole and a second detent hole and the sled chassis positioned within the sled position; and
