Housings that move using a link that slidingly engages cams
An apparatus includes a first housing having a first cam and a second housing having a second cam. A link is configured and disposed to slidingly engage these cams. The first housing moves with respect to the second housing between a first position (that comprises a stacked configuration) and a second position (that comprises a deployed configuration). The aforementioned link can include a pair of substantially collinear slots disposed therethrough. The cams, in turn, can be at least substantially pear shaped and can be disposed offset to one another and substantially longitudinally parallel to one another as well. Also if desired, such cams can be disposed on interior surfaces of both housings, and on both sides of the housings as well.
1. An apparatus comprising:
a first housing having an upper surface and having at least a first cam;
a second housing having an upper surface and having at least a second cam;
a link configured and disposed to slidingly engage both the first cam and the second cam when moving the first housing with respect to the second housing between a first position and a second position
wherein:
the first position comprises a stacked configuration with the first housing disposed atop the second housing; and
the second position comprises a deployed configuration with the upper surface of the first housing disposed at least substantially coplanar to at least a portion of the upper surface of the second housing.
2. The apparatus of claim 1 wherein the first housing includes a display and the second housing includes a keyboard.
3. The apparatus of claim 1 wherein the link includes a first slot that receives the first cam and a second slot that receives the second cam.
4. The apparatus of claim 3 wherein the first slot is disposed at least substantially collinear with respect to the second slot.
5. The apparatus of claim 1 wherein the first cam and the second cam each comprise a pear-shaped cam.
6. The apparatus of claim 1 wherein the first cam and the second cam are disposed offset and at least substantially longitudinally parallel to one another.
7. The apparatus of claim 1 wherein the first cam is disposed within an interior portion of the first housing and the second cam is disposed within an interior portion of the second housing.
8. The apparatus of claim 1 wherein the first cam is disposed on a first side of the first housing and the second cam is disposed on a first side of the second housing, and wherein:
the first housing includes a third cam;
the second housing includes a fourth cam;
a second link configured and disposed to slidingly engage the third cam and the fourth cam;
wherein the third cam, the fourth cam, and the second link are also configured such that the first housing is movable with respect to the second housing between the first position and the second position.
9. The apparatus of claim 8 wherein the first cam and the third cam are disposed on opposing sides of the first housing and the second cam and the fourth cam are disposed on opposing sides of the second housing.
10. The apparatus of claim 1 wherein the upper surface of the second housing has a non-planar upper surface and wherein the first housing has a bottom surface that at least substantially conforms to the non-planar upper surface of the second housing such that the bottom surface of the first housing interlocks with the non-planar upper surface of the second housing.
11. The apparatus of claim 10 wherein a portion of the first housing is disposed atop a portion of the second housing in the second position.
