Abstract
A locking roller assembly includes a housing adapted for mounting to an article of furniture. A wheel is rotatably mounted to the housing via a mounting arrangement that accommodates relative vertical movement between the wheel and the housing. The wheel is mounted to an axle, which in turn is secured to an axle carrier. A biasing member, such as a spring, is engaged between the housing and the axle carrier to bias the housing toward a raised position. When a load is applied to the article of furniture, the spring is compressed so as to allow the housing to move vertically downward toward the wheel. The housing includes an engagement surface that engages the wheel when the load is applied and the housing is moved downwardly, to prevent rotation of the wheel and to thereby prevent movement of the article of furniture.
