ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a swing assembly, more particularly to a swing assembly having a canopy with an adjustable inclination.
2. Description of the Related Art
FIGS. 1 and 2
illustrate a conventional swing assembly which includes a pair of spaced-apart lateral frames
11
(only one is shown), a horizontal bar
116
interconnecting upper ends of the lateral frames
11
, a seat unit
12
disposed among the lateral frames
11
and the horizontal bar
116
, a pair of linking units
120
(only one is shown) for connecting the seat unit
12
to the horizontal bar
116
, and a canopy
13
. Each of the lateral frames
11
includes a lower frame portion
111
and an upper insert rod
117
which extends vertically and which is secured to one end of the horizontal bar
116
. The lower frame portion
111
has a front leg
111
A and a rear leg
113
fastened to the front leg
111
A by means of two fasteners
112
. The front leg
111
A has a tubular connecting portion
111
B that defines an open upper end of the front leg
111
A. The insert rod
117
has a restricted lower end
117
A extending axially into the upper end of the tubular connecting portion
111
B. A pair of screw fasteners
118
extend transversely through the tubular connecting portion
111
B and the restricted lower end
117
A of the insert rod
117
for fastening the insert rod
117
to the tubular connecting portion
111
B. An inclined hanger rod
119
extends between the horizontal bar
116
and a respective one of the insert rod
117
adjacent to the corner of the horizontal bar
116
and the respective insert rod
117
. Each of the linking units
120
includes front and rear linking rods
124
,
125
which have lower ends connected pivotally to the seat unit
12
, and a hook member
110
mounted on a respective one of the hanger rods
119
and connected to upper ends of the front and rear linking rods
124
,
125
. The canopy
13
includes a rectangular canopy frame
131
which has parallel lateral rods
133
disposed above the horizontal bar
116
and welded to upper ends of the insert rods
117
, and which has a canopy member
132
mounted thereon.
The following are some of the drawbacks of the conventional swing assembly: First, as the canopy frame
131
is welded to the upper ends of the insert rods
117
, it is not possible to adjust the inclination of the canopy
13
to achieve the desired sun-blocking effect. Second, since the weights of the seat unit
12
and a person seated on the seat unit
12
are applied to the insert rods
117
and the horizontal bar
116
via the hanger rods
119
, and since the insert rods
117
are fastened to the tubular connecting portions
111
B of the front legs
111
A merely by means of two screw fasteners
118
, the connection between the insert rods
117
and the tubular connecting portions
111
B is not strong enough.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a swing assembly having a canopy with an adjustable inclination and a more durable construction.
Accordingly, the swing assembly of the present invention includes a support frame unit, a seat unit, a pair of linking units, a canopy frame and a pair of adjustable mounting units. The support frame unit includes 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 the upper end portions of the lateral frames. The seat unit is disposed among the lateral 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, and thereby suspending the seat unit above the ground surface. The canopy frame has a pair of lateral rods which are spaced-apart in the longitudinal direction of the horizontal bar, and which are perpendicular to the horizontal bar. Each of the adjustable mounting units mounts a respective one of the lateral rods on the horizontal bar, and includes a retaining member, a stationary seat, a pivot axle and an operable rotary knob. The retaining member is secured to the respective one of the lateral rods. The retaining member has a first axle hole formed therethrough, and a first end face formed with a series of first engagement teeth around the first axle hole. The stationary seat is secured to the horizontal bar, and is disposed adjacent to the retaining member. The stationary seat has a second axle hole formed therethrough. The second axle hole is aligned with the first axle hole. The stationary seat further has a second end face that confronts the first end face and that is formed with a series of second engagement teeth around the second axle hole for engaging the first engagement teeth. The pivot axle has a first end secured to the respective one of the lateral rods, and a threaded second end which extends from the first end in a direction transverse to the respective one of the lateral rods through the first and second axle holes and the stationary seat. The rotary knob is disposed adjacent to the stationary seat opposite to the second end face and threadedly engages the second end of the pivot axle. The rotary knob is operable in a first direction for threading toward the stationary seat to abut against the stationary seat so as to enable the first end face of the retaining member to contact tightly the second end face of the stationary seat and to enable the first engagement teeth to engage the second engagement teeth, thereby preventing rotation of the retaining member relative to the stationary seat about an axis of said pivot axle to prevent in turn rotation of the lateral rods of the canopy frame relative to the horizontal bar. The rotary knob is further operable in a second direction opposite to the first direction for threading away from the stationary seat, thereby releasing the first engagement teeth of the retaining member from the second engagement teeth of the stationary seat, and thereby permitting rotation of the retaining member together with the respective one of the lateral rods relative to the stationary seat and the horizontal bar so as to permit tilting adjustment of the canopy frame.
