  • Patent number: 11780485
    Abstract: 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.

  • Patent number: 11612239
    Abstract: 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.

  • Patent number: 10881212
    Abstract: A linking system for folding chairs and a method for linking folding chairs in rows. The linking system includes a first linking member having two spaced-apart, u-shaped first recesses on a first side thereof and a slit on each end thereof, wherein each slit is parallel to an axis defined by the u-shaped recesses; a second linking member having two spaced-apart, u-shaped second recesses on a second side thereof and two spaced-apart, u-shaped third recesses on a third side thereof, wherein the u-shaped third recesses are spaced further apart than the second recesses and the third side is orthogonal to the second side; and a third linking member having two spaced-apart, u-shaped fourth recesses on a fourth side thereof. The first, second and third linking members are configured to snappingly engage tubular members of adjacent folding chairs.

  • Patent number: 10485333
    Abstract: An articulated support bracket for a table and a table containing the support bracket. The support bracket includes a first arm having a proximal end and a distal end, the proximal end being rotationally attached to a frame of a table or bench; a second arm having a proximal end and a distal end, the proximal end being rotationally attached to a leg of the table and the distal end being rotationally attached to the distal end of the first arm; and a locking ring slidably disposed on the first arm between the proximal end and the distal end of the first arm for engaging a locking portion of the second arm when the locking ring is in a locking position. The locking portion has a first edge that increasingly diverges from a second edge when moving from the distal end toward the proximal end of the second arm.
