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 to 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.
L'invention concerne un ensemble de galet de verrouillage comprenant un logement à monter à un meuble. Une roue est fixée de manière rotative sur le logement par le biais d'un dispositif de montage qui effectue un mouvement vertical relatif entre la roue et le logement. La roue est montée à un axe qui, à son tour, est fixé sur un support d'axe. Un élément de polarisation, tel qu'un ressort, rentre en contact entre le logement et le support d'axe en vue de polariser le logement à une position surélevée. Lorsqu'une charge est appliquée sur le meuble, le ressort est comprimé de manière à permettre au logement de se déplacer verticalement vers le bas en direction de la roue. Ce logement comporte une surface de contact qui rentre en contact avec la roue, lorsque la charge est appliquée et le logement est déplacé vers le bas, afin de prévenir la rotation de la roue, ainsi que le mouvement du meuble.
