Claim 0:
1. A hinged safety gate comprising:
a gate frame configured to control access to an elevated work surface access area, the gate frame having a frame adjustment region, a distal upright member, an upper cross-arm, and a lower cross-arm, the upper cross-arm including an upper main tube and an upper extension tube, the upper main tube comprising a first tab that extends a first axial length beyond a distal end of the upper main tube and that comprises a first partial tube, the lower cross-arm including a lower cross-arm main portion and a lower cross-arm extension; and
a retainer assembly configured to be attached to a proximal end of the gate frame and configured to hingedly couple the gate frame to a first stationary vertical surface to permit the gate frame to swing between an open position and a closed position in which the distal upright member is positioned proximate to a second stationary vertical surface, the second stationary vertical surface opposing the first stationary vertical surface;
wherein the gate frame is movable between an extended position and an unextended position, with the upper extension tube being telescopingly slidable within the upper main tube and the lower cross-arm extension being movable relative to the lower cross-arm main portion; and
wherein the upper cross-arm further includes an upper ring clamp configured to hold the upper main tube and the upper extension tube together, the upper ring clamp having an upper ring clamp body with an axial length approximately equal to the first axial length, the upper ring clamp body comprising a first inner profile with a first tab portion that matches and mates with the first tab and with an upper extension tube portion that matches and mates with the upper extension tube, the upper ring clamp further comprising a first fastener configured to push the first tab into clamping contact with the upper extension tube and to pull the upper ring clamp body toward the upper extension tube, thereby pulling the upper extension tube into clamping contact with the first tab.
