Abstract
A telescoping gate can include a frame, a primary gate member connected to the frame in a manner such that the primary gate member can move relative to the frame, and a secondary gate member that is moveable with respect to both the primary gate member and the frame. The primary gate member can include at least one side wall, a top wall extending at an angle from a top of the side wall, and a bottom wall extending at an angle from a bottom of the side wall to create a cavity between the bottom wall, side wall and top wall. The secondary gate member can be located in the cavity of the primary gate member and configured to move relative to the primary gate member and the frame within that cavity. The bottom wall of the primary gate member includes a first roller/rail structure and the secondary gate member includes a bottom wall having a first roller/rail structure configured to mate with the first roller/rail structure of the primary gate member bottom wall. In addition, the bottom wall of the primary gate can include a roller/rail structure configured to contact a mating ground roller/rail structure.
