1. A cleaning device comprising:
- a base having a first side and an opposed second side;
a first deployment element pivotally connected to the first side of the base and pivotable from a first stowed position to a first deployed position;
a second deployment element pivotally connected to the second side of the base and pivotable from a second stowed position to a second deployed position;
a first biasing device engaging the base and the first deployment element, the first biasing device biasing the first deployment element towards the first deployed position;
a second biasing device engaging the base and the second deployment element, the second biasing device biasing the second deployment element towards the second deployed position; and
a release mechanism including an actuator button and supported by the base, the actuator button including a first arm extending from a first side of the actuator button and a second arm extending from an opposing second side of the actuator button, the first arm engaging the first deployment element to hold the first deployment element in the first stowed position, the second arm engaging the second deployment element to hold the second deployment element in the second stowed position,wherein the actuator button is configured to pivot the first arm away from the first deployment element and the second arm away from the second deployment element to disengage both of the first deployment element and the second deployment element thereby permitting the first biasing device to move the first deployment element to the first deployed position and permitting the second biasing device to move the second deployment element to the second deployed position.

Abstract
A cleaning device includes a base having a first side and a second side. A first deployment element pivotally connects to the first side of the base and is pivotable from a stowed position to a deployed position. A second deployment element pivotally connects to the second side of the base and is pivotable from the stowed position to the deployed position. In the stowed position the base, the first deployment element, and the second deployment element define a substantially rectangular perimeter. In the deployed position, the base, the first deployment element, and the second deployment element define a substantially trapezoidal perimeter.

16. A cleaning device comprising:
-
a base having a first side and an opposed second side; a first deployment element pivotally connected to the first side of the base and pivotable from a first stowed position to a first deployed position; a second deployment element pivotally connected to the second side of the base and pivotable from a second stowed position to a second deployed position; a first torsion spring for biasing the first deployment element to the first deployed position; a second torsion spring for biasing the second deployment element to the second deployed position; and a release mechanism comprising (i) a first arm for engaging the first deployment element to hold the first deployment element in the first stowed position, and (ii) a second arm for engaging the second deployment element to hold the second deployment element in the second stowed position, and (iii) an actuator button, wherein the first arm is connected to a first side of the actuator button and the second arm is connected to a second opposing side of the actuator button, the actuator button configured to move a distal end of the first arm toward a distal end of the second arm when the button is depressed; wherein, when the first deployment element is in the first stowed position and the second deployment element is in the second stowed position, the base, the first deployment element, and the second deployment element define a substantially rectangular perimeter, and wherein, when the first deployment element is in the first deployed position and the second deployment element is in the second deployed position, the base, the first deployment element, and the second deployment element define a substantially trapezoidal perimeter. - View Dependent Claims (17)
