Abstract
A power adapter including a wing deployment mechanism for retaining a wing in a first undeployed position and the second deployed position. One example may provide a housing, a spring, a spring cover, and the wing. In one example, the wing may be pivotally attached to the housing and the spring and the spring cover may be fixedly attached to the housing. The spring may contact a portion of the wing and may, in one example, apply a position dependent force to the wing that biases the wing towards either the first or the second position.
Claims23
An adapter comprising:
- a corner comprising intersecting first and second surfaces;
- a receiving depression extending around the corner, the receiving depression including a free surface having a free end located on the first surface and a pivot surface intersecting the free surface and having a pivot end located on the second surface;
- a pivotable wing comprising a free end and a cam end, the cam end including a cam and a pivot located between the cam and the free end, wherein the pivotable wing is moveable between a closed position and an open position;
- and
- a spring comprising a fixed end secured to the free end of the receiving depression and a biasing end located in the pivot end of the receiving depression and engaging with the cam of the pivotable wing so that the pivotable wing is stable in both the closed and open position.
A wing deployment system comprising:
- a substrate comprising a fixation surface and an intersecting pivot surface, wherein the fixation and pivot surfaces are non-parallel;
- a wing member comprising a pivot portion comprising a pivot end and a cam proximate to the pivot end, wherein the pivot end is pivotally connected to the pivot surface of the substrate and the wing member is movable between a first position wherein the pivot portion is parallel to the pivot surface and a second position;
- a spring comprising a fixation portion affixed to the fixation surface and extending around the intersection of the fixation surface and the pivot surface and a contacting portion contacting the cam of the wing member, wherein the spring does not contact the pivot surface of the substrate.
A method of manufacturing a wing deployment mechanism comprising:
- selecting a spring comprising a first portion extending in a first direction and a second portion extending in a second direction relative to the first portion;
- affixing the first portion of the spring to a securement portion of a spring cover, the securement portion of the spring cover extending in a first direction and a retention portion of the spring cover extending in a second direction from the securement portion;
- attaching the spring cover to a housing comprising a corner formed by the intersection of first and second surfaces such that the first portion of the spring is affixed to the housing between the securement portion of the spring cover and the first surface of the housing and such that both the second portion of the spring and the retention portion of the spring cover extend around the corner of the housing;
- pivotally attaching a wing member to the housing, wherein a cam of the wing member engages with the spring, wherein the wing member is pivotable between a first position and second position, and wherein the spring applies a force to the wing member in both the first and second positions.
