Abstract
The invention concerns a drawer slide assembly, preferably for use in appliances, comprising a catch mechanism for resisting slide extension when the drawer is in a closed position. The catch mechanism is made of a spring arm pivotally mounted to one of the rails and an anchorage point provided in the other rail. When the assembly is moved to the closed position, the anchorage point engages and rotates the spring arm about its axis. Thus, opening the drawer requires a certain force to rotate the spring back. The use of a simple spring arm reduces friction between parts, reduces assembly costs and maintains desired flexibility and tolerance for drawer production and usage.
