Abstract: A safety device is provided for a foldable chair which includes a seat, a pair of base members substantially inverted L-shaped in section each including a horizontal section fixedly mounted to an underside of the seat, a pair of first leg portions each having an upper end pivotally engaged with a first end of a vertical section of a corresponding one of the base members, a first pivot member and a second pivot member each having a first end pivotally engaged with a second end of the vertical section of a corresponding one of the base members, an elongated first slot being horizontally defined in a mediate portion of the first pivot member, a pair of second leg portions each having an upper end pivotally engaged with the second end of the first and second pivot members.

Abstract: A security device is provided for a foldable chair and includes a control member movably mounted between a pivot member and a vertical section of a base member, an elongated second slot defined in the control member and communicating with a first slot of the pivot member, a linking bar mounted between the two pivot members and having two distal ends each of which has a reduced diameter smaller than that of the linking bar to extend through the first slot of the pivot member and securely engage with a corresponding control member such that the control member is able move with the linking bar synchronously, the linking bar being restricted to slide along the first slot of the pivot member between a first position where the control member aligns with a first end of the pivot member such that the pivot member together with the control member are pivotally engaged with the base member, and a second position where the control member is moved to a position beyond the first end of the pivot member such that the pivot

Abstract: A barbecue grill assembly includes a first bowl, a second bowl disposed on the first bowl, a grate disposed on the second bowl, a bolt and a crank. The first bowl has a first bottom and a first skirt, a central tube extending from the first bottom thereof and two first slots are defined in a periphery of the central tube and each disposed diametrically opposite in the central tube, a second slot is defined in the first skirt. The second bowl has a second bottom and a second skirt, the second bottom for charcoal disposed thereon has a central hole and a plurality of vents defined therein and a long tube has a first end having a receiving hole defined therein for a stud extending downwardly from the grate inserted therein and a second end inserted in the central tube, the second end of the long tube has a U-shaped tunnel defined therein such that the bolt extends through the second slot, the first slots and the U-shaped tunnel to engage to a nut.
