Abstract: A spring fastening member includes two arms that can be engaged in a tube. A first protrusion and a second protrusion are respectively disposed at two corresponding sides of the spring fastening member in a direction away from the two sides of the spring fastening member when the two arms of the spring fastening member are forced to being parallel to each other. At the two corresponding sidewalls as viewed in a radial section of the tube, a first hole and a second hole are respectively disposed there for allowing the first protrusion and the second protrusion to be inserted there through. A first distance is defined between central axes of the first protrusion and the second protrusion, a second distance is defined between central axes of the first hole and the second hole, and the first distance is not equal to the second distance.

Abstract: A control unit is slidably mounted on a top corner of a playard and connected to the slider inside the seat through a linking unit passing through a standing post of the playard. When the control unit pulls the slider to move relative to the seat along a first direction, a braking pin slides relative to the seat along a second direction and disengages from the hub to release a wheel. When the control unit is pushed to lock the wheel, the bias force from springs moves the slider and the braking pin to slide along the opposite direction, leading the braking pin to engage with the hub to brake the wheel. The wheel can be operated to brake or release by a remote control unit.

Abstract: A chair includes a positioning unit that is provided in a receiving portion of an armrest and that includes shorter and taller stop portions. A positioning member is retained movably on a rear side of a backrest, and has one end extending into the receiving portion to abut against a selected one of the stop portions. An operating unit is connected to and is operable to move the positioning member for selectively disengaging and engaging the stop portions. A safety mechanism is provided on the backrest and the operating unit, and is operable in either a limiting state, where the positioning member is unable to move past the taller stop portion, or a non-limiting state, where the positioning member is able to move past the taller stop portion.
