SWING RACK HAVING A SEA7C DOCK WITH
ADJUSTABLE ANGLE
FIELD OF THE INVENTION
The present invention relates to a swing rack that has a
seat dock with adjustable angle and particularly to a swing
rack for providing adjustable sitting and lying angles to
enhance users comfort.
BACKGROUND OF THE INVENTION
Please refer to FIG. 1. Conventional swings that have a
single sitting or lying angle generally include a support rack
which consists of a pair of legs on two sides and a top rail
bridging the top ends of the legs, a suspension means pivotally
coupling on the top rail, a frame dock mounting on the
suspension means and a seat dock pivotally coupling on the
frame dock. The frame dock has a front bar and a rear bar
corresponding to each other. The rear bar is coupled with two
anchor mechanisms. The seat dock has a seat rack and a
backrest rack corresponding to each other. There is a bracing
bracket pivotally coupled on the backrest rack and extended
downwards. When the bracing bracket is latched on the anchor
mechanisms, the seat rack and the backrest rack form a sitting
position. When the backrest rack is latched on the rear bar of
the frame dock, the seat rack and the backrest rack are
extended flatly to form a lying position. While the swings of
such a construction can provide a sitting angle and a lying
a

CA 02479701 2004-08-30
angle, they still have drawbacks, notably:
1. The center portion of the seat dock is hollow whether at
the sitting angle and lying angle. Users .are supported only by
the seat dock cover. Moreover, the seat dock and the legs are
coupled only by fastening plates through a pivot bar set, the
fastening plates cannot provide sufficient bracing strength
when people are lying -down, hence they could sag abruptly
and cause ill comfort to people. Their capability for
supporting the load also is a concern. :Moreover, the pivotal
to joint of the seat rack and the backrest rack is movable. In the
event of the receiving force being uneven (such as user sits on
the seat rack first, then lies down slowly, the weight first
concentrates on the pivotal joint of the seat rack and the
backrest rack), the pivotal joint will he moved downwards
abruptly and cause the backrest rack folding to the seat rack.
It is prone to squeeze people and results in injury.
2. Besides the circumstance mentioned above, the abrupt
folding also relates to the situation where the bracing bracket
is anchored only when latching on the anchor mechanisms. In
2o the lying condition, the bracing bracket has no anchor means.
Thus when the abrupt folding occurs, the bracing bracket
moves upwards and sways. It tends to hit users and cause
injury. Moreover, in the event that users want to move the
swing location, as the bracing bracket is not properly latched
on the anchor mechanisms, it will sway and hit the rear bar.
2

CA 02479701 2004-08-30
The enameled surface of the rear bar and bracing bracket
could be scraped and result in a damaged appearance.
SUMMARY OF THE INDENTION
Therefore the primary object of the invention is to solve
the aforesaid disadvantages and eliminate the shortcomings.
The invention provides' a swing rack that has a seat dock with
adjustable angle. It has anchor docks on two sides of the
loading frame. The anchor dock has a trough to hold a sliding
member which is coupled with seat dock consisting of a seat
1o rack, a backrest rack and a bracing bar bridging the seat rack
and the backrest rack. A bracing bracket is provided which has
a retaining element. The loading frame has a first anchor
element corresponding to the retaining element. The stretcher
between the legs has a second anchor element. The bracing
bracket may be latched respectively on the first anchor
element and the second anchor element ;at the sitting and lying
angles and to be confined by the retaining element. Thus users
may have a desired support both at the sitting and lying angles,
and the bracing bracket may be securely anchored.
2o The foregoing, as well as additional objects, features
and advantages of the invention will be more readily apparent
from the following detailed description, which proceeds with
reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT
Please referring to FIGS. 2A, 2B, 4 and 5, the swing rack
1 according to the invention has a seat dock 40 with an
2o adjustable angle. It mainly includes a support rack 10 which
consists of legs 11 on two sides and a top rail 12 bridging the
top ends of the legs 11. The top rail 12 is coupled with two
suspension units 20 on two sides. The suspension units 20
hang a frame dock 30 at the bottom end. The frame dock 30
includes two side frames 31 and a loading frame 32 bridging
4

CA 02479701 2004-08-30
the side frames 31. The loading frame 32 holds a seat dock 40
thereon. As shown in FIGS. 4 and S, the loading frame 32 has
anchor docks 60 on two sides. Each anchor dock 60 includes
an anchor member 61 for fastening to the loading frame 32
through a fastening element 611. The anchor dock 60 has a
trough 601 for holding a sliding member 63. The seat dock 40
includes a seat rack 41 and a backrest rack 42 that have one
end pivotally coupled on the sliding member 63 in a coaxial
manner through a fastening element 62. The coupling end of
to the seat rack 41 and the backrest rack 42 is further coupled
with a bracing bar 43. The anchor dock 6D has retaining slot
612 on one side and a sliding slot 613 on another side facing
the coupling end of the seat rack 41 and the backrest rack 42.
The sliding slot 6I3 has an opening end 614 and a retaining
end 61 S. The sliding member 63 has a transverse slot 632 on
one side corresponding to the retaining end 61 S and a
fastening hole 631 on another side corresponding to the
retaining slot 612. For assembly, slide the coupling end of the
seat rack 41 and the backrest rack 42 into the sliding slot 613
from the opening end 614, insert the fastening element 62
through the transverse slot 632 of the sliding member 63 to
engage with the coupling end of the seat rack 41 and the
backrest rack 42. Fasten a retaining element 633 through the
retaining slot 612 and the fastening hole 631 to anchor the
sliding member 63 on the anchor dock 60. Furthermore, the
s

CA 02479701 2004-08-30
backrest rack 42 is pivotally coupled with a bracing bracket
44. The backrest rack 42 and the seat rack 41 may be adjusted
to form a sitting angle for seating people. The bracing bracket
44 has a retaining element 50. The loading frame 32 has a first
anchor member 33 corresponding to the retaining member 50
so that the bracing bracket 44 may be latched on the first
anchor member 33 to form the sitting angle and be confined
by the retaining element 50 for anchoring. When the backrest
rack 42 and the seat rack 41 axe adjusted to the lying angle, a
1o stretcher 13 of the legs l 1 has a second anchor member 131 to
latch the bracing bracket 44 for anchoring.
Referring to FIGS. 2B, 3A and 3B, when the backrest rack
42 and the seat rack 41 are adjusted to the lying angle, they
are extended flatly about 180 °. In that condition, the bracing
IS bracket 44 may be latched on the second anchor member 131
for anchoring. The second anchor member 131 has an opening
132 larger than the tube diameter of the bracing rack 44 so
that the bracing rack 44 may be latched through the opening
132 without generating swaying forwards and backwards.
20 When there is a desire to move the swing rack 1, the bracing
rack 44 may be anchored securely without swaying to prevent
scraping the enameled surface and dannaging the appearance.
In addition, the bracing bar 43 bridging the coupling ends of
the seat rack 41 and the backrest rack 42 can provide
25 improved support when users lie on the lying angle.

Referring to FIGS. 2C, 6A and 6B, when users want to
change the swing rack 1 to the sitting angle, first, release the
latching relationship between the bracing bracket 44 and the
second anchor member 131; move the backrest rack 42
upwards relative to the seat rack 41, and in the mean time, the
bracing bracket 44 is moved upwards; latch the bracing
bracket 44 through the opening 331 into the first anchor
member 33; a slot 51 coupled with a confining element S2 for
anchoring the retaining element 50 on the bracing bracket 44
to and a retaining section 53 extem:ded from one end
corresponding to the opening 132. As shown in FIG. 2B, the
retaining section 53 may be latched through the opening 331
to fill the gap between the bracing bracket 44 and the first
anchor member 33 to form a secured anchoring relationship.
When the backrest rack 42 is adjusted relative to the seat rack
41 to form the sitting angle, as the seat rack 41, backrest rack
42 and bracing bar 43 are pivotally coupled with the sliding
member 63, and the sliding member 63 is moved downwards
in the trough 601 of the anchor dock 60 until reaching the
2o bottom where the bracing bracket 44 is latched on the first
anchor member 33 as shown in FIG. 3C, the bracing bracket
44 may be anchored on the first anchor member 33 through
the retaining element 50, and the fastening element 62 may be
moved transversely in the transverse slot 632 of the sliding

shown in FID. 3D; thereby the sitting angle may be obtained.
Similarly, the bracing bar 43 can provide reinforced support to
bear the weight. And the coupling end of the seat rack 41 and
the backrest rack 42 may be prevented from being confined to
the retaining end 61 S and the first anchor member 33, thereby
abnormal moving of the backrest rack 4-2 may be avoided to
provide a double safeguard effect. Thus the entire swing 1 is
more comfortable and safer in use.
