Abstract
Abstract A resilient restraining member for use with a cabinet having a drawer. The cabinet includes a rail integral with the drawer, a run secured to the cabinet and transport means secured to the drawer. The resilient restraining member has a first spring portion at one end adapted to be attached to the run and a second spring portion at the other end adapted to normally extend into the run. The transport means is disposed to travel along the run and to urge the second spring portion out of its path of travel as the drawer is moved toward a closed position. The second spring portion thereafter returns to its normal position extending into the run to cooperate with the transport means to releasably retain the drawer in the closed position. The transport means again is disposed to travel along the run and to urge the second spring portion out of its path of travel as the drawer is later moved toward an open position. The resilient restraining member prevents unintentional movement of the drawer from the closed position to the open position. The cabinet or its environment can therefore be moved without consequent movement of the closed drawer. With these features of construction, the resilient restraining member provides a cabinet drawer restrainer useful with any cabinet having a drawer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
240 words
In a cabinet having a drawer, and including a rail provided by said drawer, a run secured to said cabinet and a roller secured to said drawer, said run being generally in the form of a C-shaped channel having spaced top and bottom members joined by a side member, said top member being interrupted along its length to define a detent-receiving opening, the improvement comprising a resilient restraining member having a spring clip portion joined to said run and a spring detent portion normally extending into said run, said roller being disposed to travel along said run and to urge said spring detent portion out of its path of travel as said drawer is moved toward a closed position, said spring detent portion thereafter returning to its normal position extending into said run to cooperate with said roller to releasably retain said drawer in said closed position, said roller again being disposed to travel along said run and to urge said spring detent portion out of its path of travel as said drawer is later moved toward an open position, said bottom member including a reverse indent extending into said run in the path of travel of said roller below and spring detent portion, whereby, said resilient restraining member and said reverse indent prevent unintentional movement of said drawer from said closed position to said open position that might otherwise be caused by movement of said cabinet or its environment.
Claim 2
Dependent Claim
