Abstract: A freezer chest for storing and displaying frozen foods such as packaged ice cream products for sale to retail customers includes a modular storage bin in which a product stack plate is mounted on a helical support spring. Packaged ice cream products are loaded onto the product stack plate. The product stack plate, urged by the helical spring, advances the stack of frozen products to the top of the storage bin as products are removed by customers. A permanent magnet mounted on the product stack plate generates a magnetic field that couples with position sensors mounted in a vertical array along the storage bin. Each sensor produces an output signal in response to coupling alignment of the magnetic field with the sensor as the stack plate moves through the storage bin. The helical support spring extends the stack plate incrementally in proportion to the weight load removed as each packaged product is unloaded.
