Patent number: 11780485Abstract: A trolley configured for use to carry folding tables of a variety of sizes. The trolley includes a loading end, a trolley frame, and an extension gate adjustably connected to the trolley frame so as to be adjustable relative to the loading end of the trolley in a length direction of the trolley. The extension gate includes an elongate member slidingly disposed on the trolley frame and a rotatable portion that is foldable relative to the elongate member and lockable in an upright position by a lock. The rotatable portion may be positioned in an extended position from the loading end of the trolley, in a retracted position adjacent the loading end of the trolley, and in positions that are intermediate to the extended position and the retracted position. The elongate member may slide in a first direction to extend the rotatable portion away from the loading end of the trolley and in a second direction to retract the rotatable portion toward the loading end of the trolley.Type: GrantFiled: September 30, 2021Date of Patent: October 10, 2023Assignee: Zhuhai Shichang Metals Ltd.Inventors: Hai Yu, Che-Jen Wang

Patent number: 11612239Abstract: A table includes collapsible telescopic legs and a height adjustment mechanism. The height adjustment mechanism includes a pair of latch arms and an activation device. When pushed downward, the activation device engages with the latch arms to cause the latch arms to move inward. The inward motion is opposed by a biasing mechanism disposed between the latch arms. As the latch arms move inward, tabs at the ends of the latch arms disengage from notches on the telescopic legs to allow the legs to be extended or retracted. When the activation device is released, the tabs engage with the notches to lock the legs at a selected height position.Type: GrantFiled: July 14, 2021Date of Patent: March 28, 2023Assignee: Zhuhai Shichang Metals Ltd.Inventor: Jingbo Liu
