Patent number: 6510960Abstract: A captivated slidable access cover incorporates an integral cantilevered spring to prevent undesired movement resulting from gravitational forces or vibration. The cover has two generally parallel, opposed edges which are slidingly captivated in opposed tracks of the enclosure. The integrally formed cantilevered spring is located adjacent one end of the cover and biases the cover to be in one of a positively open position or a positively closed position. The cantilevered spring presses against a portion of the enclosure at or adjacent one end of the access opening defined in the enclosure. The biased interaction between the cantilevered spring and the enclosure ensures a positive open or closed position of the cover. The cover also includes a handle at its other end for slidably opening and closing the cover.Type: GrantFiled: August 25, 2000Date of Patent: January 28, 2003Assignee: Square D CompanyInventors: David G. Christopherson, Ronald A. Banister
