Abstract:
A swing assembly comprising:a support frame unit including a pair of spaced-apart lateral frames with lower end portions adapted to be supported on a ground surface, and upper end portions, and a horizontal bar interconnecting said upper end portions of said lateral frames; a seat unit disposed among said lateral frames and said horizontal bar; a pair of linking units spaced apart along a longitudinal direction of said horizontal bar, each of said linking units having an upper end connected pivotally to said horizontal bar, and a lower end connected pivotally to said seat unit, thereby suspending said seat unit above the ground surface; a canopy frame having a pair of lateral rods which are spaced-apart in the longitudinal direction of said horizontal bar and which are perpendicular to said horizontal bar; and a pair of adjustable mounting units for mounting a respective one of said lateral rods on said horizontal bar, each of said mounting units including a retaining member secured to the respective one of said lateral rods, said retaining member having a first axle hole formed therethrough, and a first end face formed with a series of first engagement teeth around said first axle hole, a stationary seat secured to the horizontal bar and disposed adjacent to said retaining member, said stationary seat having a second axle hole formed therethrough, said second axle hole being aligned with said first axle hole, said stationary seat further having a second end face that confronts said first end face and that is formed with a series of second engagement teeth around said second axle hole for engaging said first engagement teeth, a pivot axle having a first end secured to the respective one of said lateral rods, and a threaded second end which extends from said first end in a direction transverse to the respective one of said lateral rods through said first and second axle holes and said stationary seat, and an operable rotary knob disposed adjacent to said stationary seat opposite to said second end face and threadedly engaging said second end of said pivot axle, said rotary knob being operable in a first direction for threading toward said stationary seat to abut against said stationary seat so as to enable said first end face of said retaining member to contact tightly said second end face of said stationary seat and to enable said first engagement teeth to engage said second engagement teeth, thereby preventing rotation of said retaining member relative to said stationary seat about an axis of said pivot axle to prevent in turn rotation of said lateral rods of said canopy frame relative to said horizontal bar, said rotary knob being further operable in a second direction opposite to the first direction for threading away from said stationary seat, thereby releasing said first engagement teeth of said retaining member from said second engagement teeth of said stationary seat, and thereby permitting rotation of said retaining member together with the respective one of said lateral rods relative to said stationary seat and said horizontal bar so as to permit tilting adjustment of said canopy frame.
