Abstract:
1. A device comprising: a first body portion having a first connecting edge and a second connecting edge; a second body portion having a first connecting edge and a second connecting edge, wherein the first body portion and the second body portion, at least in part, define a base orientation of the device and wherein an open space is defined between the first body portion and the second body portion; a first spring member having a first connecting edge and a second connecting edge, wherein the first connecting edge of the first spring member contacts and is pivotally engaged with the first connecting edge of the first body portion and the first connecting edge of the second body portion at multiple independent locations; and wherein the second connecting edge of the first spring member contacts and is pivotally engaged with the second connecting edge of the first body portion and the second connecting edge of the second body portion at multiple independent locations; a first shaft connecting the first connecting edges of the first body portion, the second body portion, and the first spring member in a pivotal manner; and a second shaft connecting the second connecting edges of the first body portion, the second body portion, and the first spring member in a pivotal manner, wherein a force applied to at least one of the first body portion or the second body portion so as to change the device out of the base orientation causes the first spring member to stretch under a tensile force and exert a force that urges the device toward the base orientation.
