Abstract: An ice chest has retractable, telescoping legs extending at respective forward and rearward angles from each respective endwall of the ice chest. The ice chest has handles at the upper central portion of the ice chest endwall having push buttons therein which release the telescoping legs from a locked position and which fall to the open position under their own weight and lock in a secure position. The push buttons actuate the locks by a linkage system. The front legs have pads at their lower ends, protecting the ends of the legs, and providing weight to pull the legs into the open, locked position. The rear legs have wheels which also providing weight to pull the legs into the open, locked position. A similar water cooler has retractable legs which have pads on their lower ends pulling the legs downward upon pushing buttons on handles on the sidewalls.

Abstract: A thermal actuator includes a first arm having a proximal end and a distal end, a second arm, parallel to the first arm, having a proximal end and a distal end, and a third arm arranged between and parallel to the first and second arms, the third arm having a proximal end and a distal end. The third arm has at least one portion at the distal end of the third arm having a width that is substantially larger than a width of the first arm and a width of the second arm. The distal ends of the first, second and third arms are coupled together to form a distal end of the thermal actuator, and the first, second and third arms preferably are made of a single material. A number of thermal actuators can be arranged in an array. The thermal actuator or array of thermal actuators can be coupled to an applicator.
