Description
FIELD OF THE INVENTION
This invention relates to a folding reclining chair with arms that is suitable
for travel and leisure and that can be used in a variety of environments including,
for example, in households, outdoors, in a courtyard, in a park, and at the beach.
BACKGROUND OF THE INVENTION
The existing folding bed suitable for travel and leisure mainly has two structures.
One uses an assembly-type structure composed of a plurality of U-shaped rectangular
frames, with the fabric being able to be stretched tight. This is comfortable for
sitting and lying, but has a large volume when folded, and is thus inconvenient
for carrying and depositing. The other uses a plurality of crossed supports connected
together, and has a small volume when folded, but the fabric is unable to be stretched
tight because the fabric is connected to the bed support via some fixing points.
When a person sits, lies, or sleeps on the bed, the bed will sink undesirably and
for this reason is uncomfortable in use. In addition, the bed body support structure
has poor strength and therefore can bear only a relatively small load. Thus, after
a period of use or upon bearing a heavy load, the bed plane is likely to tear.
SUMMARY OF THE INVENTION
The present invention provides a folding reclining chair with arms that overcomes
the above-mentioned defects of conventional folding reclining chairs. The front
support of the reclining chair body support is configured to form a quadrangular
structure. The rear support employs crossed supports and has folding arms, which
enforces the strength of the reclining chair body support structure. The reclining
chair plane is fitted onto the reclining chair body support, and thus can easily
be stretched tight. A person feels comfortable when sitting, lying, or sleeping
on the reclining chair surface, with both hands resting on the arms, thus achieving
an object of comfort and convenience.
In one embodiment, the folding reclining chair with arms includes a reclining
chair body support, arms, and a reclining chair plane. The reclining chair body
support includes a front support and a rear support. The front support includes
a foot-rest rod, a front leg tube, a front support rod, a rear support rod, a connection
rod, and a pair of front crossed rods. The rear support includes a seating frame
rod, a back-rest rod, a middle crossed rod, and a rear crossed rod.
The front end of the foot-rest rod is connected to the front support rod via
a fixing element. One end of the rear support rod is connected to the middle portion
of the foot-rest rod via a fixing connection element, and the other end of the
rear support rod is connected to the lower portion of the back-rest rod. One end
of the connection rod is connected to the rear support rod, and the other end of
the connection rod is connected to the front support rod via a sliding sleeve.
The front leg tube is connected to the rear support rod through the sliding sleeve.
The foot-rest rod, front support rod, rear support, and connection rod form a quadrangular
structure so that the position of the front leg tube can be adjusted conveniently
by means of the sliding sleeve along with the folding and unfolding of the integral
reclining chair frame. One end of the front crossed rod is connected to the rear
support rod via a U-shaped hinging element and the other end is connected to the
sliding sleeve. The rear end of the foot-rest rod is connected to the seating frame
rod via a rotary connection element, and the seating frame rod is hinged to the
back-rest rod. One end of the middle crossed rod is connected to the seating frame
rod, and the other end of the middle crossed rod is connected to the lower portion
of the back-rest rod. One end of the rear crossed rod is connected to the upper
portion of the back-rest rod via a U-shaped hinging element, and the other end
thereof is connected to the lower portion of the seating frame rod.
The arms may be rigid or soft. When rigid arms are used, the arm support rod
is connected to the upper portion of the seating frame rod by means of an arm support
rod fixing element. One end of the rigid arm is connected to the back-rest rod,
and the other end to the arm is connected to the support rod. When soft arms are
used, the arms are disposed at the upper portion of the middle crossed rod, and
the middle crossed rod is connected to the seating frame rod via a U-shaped hinging element.
The folding reclining chair plane is fitted onto the foot-rest rod, the seating
frame rod, and back-rest rod of the reclining chair body support.
The operation principles of the folding reclining chair with arms will now be
described. To use the folding reclining chair, the seating frame rod and the back-rest
rod are pushed apart. At this time, the rear support rod automatically unfolds
the front support rod and foot-rest rod, and the front leg tube slides along with
the sliding sleeve mounted on the front support rod and the connection rod. The
reclining chair body and reclining chair plane are then unfolded at once. When
the sliding sleeve slides upward to the limiting position portion, the reclining
chair frame is fully unfolded for use. To fold the folding reclining chair, the
seating frame rod and back-rest rod are folded inward. At the same time, the rear
support rod and foot-rest rod are pulled inward to cause the quadrangular structure
to fold, and the sliding sleeve moves downward to the lower portion of the front
leg tube to cause the reclining chair plane and the entire support to fold into
a package for carrying.
The folding reclining chair with arms is elegantly designed and has a compact
structure. The entire reclining chair can be freely folded and unfolded because
the reclining chair body foot-rest rod, the front support rod, rear support, and
the connection rod form a quadrangular structure, and the rear support uses a crossed
support and has folding arms. In addition, the reclining chair becomes small when
folded. When the reclining chair is unfolded, because the seating frame rods and
the back-rest rods are connected from front to rear to form two side frames of
the folding reclining chair and the reclining chair plane fabric is fitted onto
these rods at both sides, the reclining chair plane fabric gradually stretches
tight along with the unfolding of the supports and has a uniform force. A person
feels comfortable when lying on the reclining chair. The reclining chair body support
structure has a high strength and a large bearing load. The folding reclining chair
with arms can be used as a deck reclining chair, sleeping reclining chair, and
sitting reclining chair as well. The reclining chair is safe and reliable when
a person sits on different positions of the reclining chair body support. As the
reclining chair is provided with rigid or soft arms, a person sitting or resting
on the reclining chair may lean on the arms. And the folding reclining chair is
comfortable in use and convenient to fold and carry.
