Linkage assembly for a portable electronic device

A portable electronic device including a housing having (i) a first housing part, and (ii) a second housing part, the portable electronic device comprising:

• a linkage assembly that is (i) joined to the first housing part and the second housing part, and (ii) capable of pivoting the first housing part relative to the second housing part, the linkage assembly including:
• a first link that is joined to a first joint and a second joint of the first housing part,
• a second link that is joined to the second joint and a third joint of the second housing part,
• a third link that is joined to the third joint and a fourth joint of the second housing part, and
• a fourth link that is joined to the first joint and the fourth joint, wherein the second link is longer than the fourth link such that when an input force is applied to the fourth link that causes the fourth link to oscillate, the oscillation of the fourth link drives the second link, causing the housing to transition between an open configuration to a closed configuration.

A portable electronic device, comprising:

• a first case;
• a second case;
• and
• a linkage assembly that pivotally couples the first case with the second case, wherein the linkage assembly includes:
• a first link that is coupled to a first set of joints, wherein the first set of joints are coupled to the first case and the second case, and
• a second link that is longer than the first link, the second link coupled to (i) the first link, and (ii) a second set of joints of the first case and the second case, wherein when the first case and the second case define a closed configuration and an input force is applied to the first link, (i) the first link translates in a first direction towards the second link, and (ii) the second link translates in a second direction that causes the first case and the second case to transition from the closed configuration to an open configuration, the second direction being different from the first direction.
