ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a swing assembly, more particularly to a swing assembly including a pair of lateral canopy frames which can be easily assembled to a canopy sheet to form a canopy that is kept in a tensioned state.
2. Description of the Related Art
FIG. 1
illustrates a conventional swing assembly which includes a pair of spaced-apart side frames
11
, a horizontal bar
12
extending between upper ends of the side frames
11
, a seat unit
13
disposed among the side frames
11
and the horizontal bar
12
and suspended on the horizontal bar
12
, and a canopy
14
. The canopy
14
includes a rectangular canopy frame
140
mounted on upper ends
111
of the side frames
12
. The canopy frame
140
is constituted by a pair of U-shaped rods
15
on lateral sides, and a pair of elongated rods
16
on front and rear sides. Each of the elongated rods
16
has restricted end sections
161
, each of which extends into a respective tubular end of the U-shaped rods
15
, as shown in FIG.
2
. Before the elongated rods
16
are assembled to the U-shaped rods
15
, each of the elongated rods
16
and the U-shaped rods
15
extends through a respective retaining sleeve
171
on a canopy sheet
17
for retaining the canopy sheet
17
on the canopy frame
140
. The elongated rods
16
can be assembled to the U-shaped rods
15
only after the elongated rods
16
and the U-shaped rods
15
are sleeved with the retaining sleeves
171
of the canopy sheet
17
. As such, the canopy sheet
17
is designed to have a size sufficient to permit insertion of the restricted end sections
161
of the elongated rods
16
into-the tubular ends of the U-shaped rods
15
. Therefore, the canopy sheet
17
can hardly be kept in a tensioned state after assembly. The appearance of the canopy
14
is not satisfactory. Moreover, rain could accumulate on top of the canopy sheet
17
to ultimately result in collapse or breakage of the canopy
14
.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a swing assembly including a pair of lateral canopy frames which can be easily assembled to a canopy sheet to form a canopy that is kept in a tensioned state.
Accordingly, the swing assembly of the present invention includes a support unit, a seat unit, a pair of linking units, and a canopy unit. The support unit includes a pair of spaced-apart side frames with lower end portions adapted to be supported on a ground surface, and upper end portions, and a horizontal bar extending between and interconnecting the upper end portions of the side frames. The seat unit is disposed among the side frames and the horizontal bar. The linking units are spaced-apart along a longitudinal direction of the horizontal bar. Each of the linking units has an upper end connected pivotally to the horizontal bar, and a lower end connected pivotally to the seat unit, thereby suspending the seat unit above the ground surface. The canopy unit includes a pair of lateral canopy frames which are spaced-apart in the longitudinal direction, and a flexible canopy sheet. Each of the canopy frames includes a horizontal bottom rail transverse to the horizontal bar, and an upright main frame member which is disposed above the bottom rail and which extends in a direction along the length of the bottom rail. The main frame member is fastened to the bottom rail, and is mounted on the upper end portion of a respective one of the side frames of the support unit. The canopy sheet spreads across and over the canopy frames, and has a surface which confronts the canopy frames and which is formed with a pair of retaining sleeves that are sleeved respectively on the bottom rails of the canopy frames.
