Abstract: A folding support structure includes a top support and a leg assembly. The top support has a pivot connector and an assembler, wherein the assembler has an assembling surface. The leg assembly includes a column, which includes a pivotally connected end, a free end, and a wing. The column is pivotally connected to the pivot connector of the top support with the pivotally connected end thereof, whereby the column is pivotable relative to the top support. The wing of the column has an abutting surface. When the column pivots to an unfolded position, the abutting surface of the wing contacts the assembling surface of the assembler, and is secured thereto through a fixing connection approach. By folding a top and legs of a desk, the total volume could be reduced, benefiting the cargo capacity utilization, which therefore increases the shipping efficiency. Furthermore, such a desk can be easily assembled.

Abstract: A reciprocating device applied to a load-bearing member includes a motor, an eccentric wheel, a first pulley disposed on a movable base of the load-bearing member, a first belt, and a recovery mechanism disposed on the movable base. The motor and the eccentric wheel are disposed on a fixed base of the load-bearing member. The eccentric wheel is connected to the motor to be driven to rotate around an eccentric shaft of the eccentric wheel. The first belt surrounds the eccentric wheel and the first pulley. The eccentric wheel is operatively coupled to the first pulley via the first belt. When the eccentric wheel is rotated by the motor, the first pulley and the movable base connected to the first pulley is operatively coupled to the eccentric wheel. The recovery mechanism provides a reverse force to the movable base according to said linkage.

Abstract: A wheelchair comprises a chair frame, two armrest support rods, two armrests, a plurality of wheels, and at least one pedal mechanism. The two armrest support rods connect the chair frame in a telescopic manner, and located at two sides of the chair frame, respectively. The two armrests connect the two armrest support rods, respectively, and can be moved forward and backward relative to the connected armrest support rods in a horizontal direction. The plurality of wheels connects a base portion of the chair frame. The at least one pedal mechanism includes a connecting rod and a foot pedal. The connecting rod is pivotally mounted at a front side of the chair frame, and the foot pedal is pivotally connected to the connecting rod, so that the connecting rod may drive the foot pedal to pivot about the pivotally connected end. Similarly, the foot pedal can also pivot relative to the connecting rod. Through the above design, the wheelchair can be adjusted according to the user's physique and requirement.
