Abstract: An infant stroller having a fold latch mechanism to lock the stroller in the unfolded or deployed configuration. The side of the stroller contains a latchkey piece having a pocket-like recess that engages a latchpin on the stroller's front leg. When the latchkey is in the locked position, the front legs are held in place, locking the stroller in the unfolded or deployed configuration. When the latchkey is disengaged from the latchpin on the front leg, the front leg can be rotated to allow the stroller to be folded for storage or transport. The stroller also has a latching mechanism for locking the tray unit in place during normal use. The tray unit becomes unlocked and can be tucked away during the folding process.

Abstract: A case for holding writing utensils includes a body having an outer surface and a retaining surface. The outer surface of the body is configured for placement on a substantially horizontal surface. The retaining surface has at least one first recess configured to frictionally retain a portion of a writing utensil at a first angle with respect to the horizontal surface such that an end portion of the writing utensil obliquely extends from the retaining surface. The case may include at least one first channel and at least one second channel are defined within the inner surface along first and second gradients, respectively. The first gradient slopes upward from a front end of the first channel to a rear end of the first channel. The second gradient slopes downward from a front end of the second channel to a rear end of the second channel. The first and second channels are each configured to retain a portion of a writing utensil.
