Abstract

See full text

A ladder comprises a front leg and a rear leg connected by a slider bracket. The slider bracket comprises a base and a track. The base comprises an aperture therein. The track extends away from the base and comprises a slot therein. The base is rotatably coupled to the front leg by a front pin in the aperture. The track is slidably coupled to the rear leg by a rear pin in the slot. When spreading the rear leg away from the front leg, the base pivots around the front pin as the rear pin slides in the slot of the track until the rear pin reaches the end of the slot in the track. The slot also may include a latch at the end of the slot that engages the rear pin.
