[0001] This application claims the priority benefits of Chinese
application serial no. 201810529337.X, filed on May 29, 2018, and
Chinese application serial no. 201820811854.1, filed on May 29,
2018. The entirety of each of the above-mentioned patent
applications is hereby incorporated by reference herein and made a
part of specification.
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The invention relates to a tent, and particularly relates to
a structurally reinforced tent frame and a central reinforcing
structure thereof.
2. Description of Related Art
[0003] Tents/Canopies are outdoor products commonly used in daily
activities of people. A tent/canopy usually includes a support
frame and a tarpaulin. In order to be carried around easily, the
support frame is commonly designed to have a foldable frame
structure.
[0004] Chinese Utility Model Patent No. CN205918220U discloses a
canopy frame for alleviating standing water, which includes foot
poles, hinged crossbeams, frame supporting poles, and a top plate.
The foot poles are vertically arranged. A bottom portion of the
foot pole stands on the ground, a top portion of the foot pole is
hinged with one end of the frame supporting pole, and another end
of the frame supporting pole is connected with the top plate. Top
portions of two adjacent foot poles are connected by the hinged
crossbeam. In addition, the canopy frame is characterized in
further including pull rods and a top plate supporting pole
assembly. One end of the pull rod is hinged with the top plate, the
other end of the pull rod is hinged with a hinge point of the
hinged crossbeam. Moreover, the top plate supporting pole assembly
is located below the top plate and is respectively hinged with each
of the frame supporting poles and each of the pull rods. According
to the specification and drawings of CN205918220U, a base plate of
the canopy is connected with the pull rods and the frame supporting
poles. If the above structure is adopted, since each of the pull
rods and each of the frame supporting poles need to be connected
with the base plate when the canopy is being installed, the base
plate may be too thin and weak, which makes the canopy frame
unstable. Also, the installation structure is complicated, which
makes it difficult for installation and maintenance to take
place.

unfolded, so the frame is stable.
[0018] (2) The number of connections of the first tarpaulin
supporting poles and the second tarpaulin supporting poles on the
lower plate is reduced, so the sturdiness of the lower plate is
increased. In addition, due to the reduced number of connections of
the first tarpaulin supporting poles and the second tarpaulin
supporting poles, the gap for installation between the first and
second tarpaulin supporting poles is increased. Therefore, the
first and second tarpaulin supporting poles can be installed and
maintained more easily.
[0019] (3) Since the four second tarpaulin supporting poles are
added, the force received by the tarpaulin is more sparsely
distributed. Therefore, standing water on the tarpaulin can be
effectively alleviated. Besides, with the supportive intervention
of the second tarpaulin supporting poles, strength of a side hinge
is reinforced.

DESCRIPTION OF THE EMBODIMENTS
[0026] Reference will now be made in detail to the exemplary
embodiments of the invention, examples of which are illustrated in
the accompanying drawings. Wherever possible, the same reference
numbers are used in the drawings and the description to refer to
the same or like parts.
[0027] In the following, the embodiments of the invention will be
described in detail with reference to the accompanying
drawings.
Embodiment 1
[0028] As shown in FIGS. 1 and 2, a structurally reinforced tent
frame includes four standing poles 1. A connecting base 7 and a
slidable base 2 are disposed on the standing pole 1. In addition,
the connecting base 7 is fixed at the top portion of the standing
pole 1, and the slidable base 2 is sleeved to the standing pole 1
and is slidable relative to the standing pole 1. A first tarpaulin
supporting pole 5 is hinged on the connecting base 7, and another
end of the first tarpaulin supporting pole 5 is hinged with a top
plate 9. An auxiliary supporting pole 4 is hinged on the first
tarpaulin supporting pole 5, and another end of the auxiliary
supporting pole 4 is hinged with the slidable base 2. The first
tarpaulin supporting pole 5 is formed by two or more supporting
poles hinged with each other. Through sliding of the slidable base
2, the auxiliary supporting pole 4 is driven, so as to drive and
fold the first tarpaulin supporting pole 5.
[0029] A hinged crossbeam 3 is disposed between two adjacent
standing poles 1. Ends of the crossbeam 3 are respectively
connected with the connecting base 7 and the slidable base 2 on the
standing poles 1. A hinge point of the hinged crossbeam 3 is hinged
with a second tarpaulin supporting pole 6. Another end of the
second tarpaulin supporting pole 6 is hinged with a top plate 9.
The second tarpaulin supporting pole 6 is formed by two or more
supporting poles hinged with each other. Through sliding of the
slidable base 2, the hinged crossbeam 3 is driven and folded.
[0030] There are four first tarpaulin supporting pole 5 and four
second tarpaulin supporting poles 6. In addition, the four second
tarpaulin supporting poles 6 and any two first tarpaulin supporting
poles 5 that are arranged on a diagonally are connected to
supporting poles 8. Other ends of the supporting poles 8 are hinged
with a lower plate 12, and a retractable position-limiting pole is
disposed between the lower plate 12 and the top plate 9.
[0031] According to the embodiments of the invention, the
directions in which the second tarpaulin supporting poles 6 are
opened are controlled by the retractable position-limiting pole,
and the force received by the second tarpaulin supporting poles 6
is uniformly fed back to the first tarpaulin supporting poles 5, so
that the entire structure is stably supported.
[0032] In one embodiment, the retractable position-limiting pole
includes a first position-limiting pole 10 fixed with the top plate
9 and a second position-limiting pole 11 fixed with the lower plate
12. An outer diameter of the first position-limiting pole 10 is
smaller than an inner diameter of the second position-limiting pole
11. The second position-limiting pole 11 is sleeved to exterior of
the first position-limiting pole 10. In addition, the first
position-limiting pole 10 is movable inside the second
position-limiting pole 11 in an upper-lower direction.
[0033] In another embodiment, the retractable position-limiting
pole includes the first position-limiting pole 10 fixed with the
top plate 9 and the second position-limiting pole 11 fixed with the
lower plate 12. An inner diameter of the first position-limiting
pole 10 is greater than an outer diameter of the second
position-limiting pole 11. The first position-limiting pole 10 is
sleeved to exterior of the second position-limiting pole 11. In
addition, the second position-limiting pole 11 is movable inside
the first position-limiting pole 10 in the upper-lower
direction.
[0034] As shown in FIG. 3, the two embodiments have the following
characteristics.
[0035] Assuming that two ends of the first position-limiting pole
10 are respectively labeled as A and B, and two ends of the second
position-limiting pole 11 are respectively labeled as C and D,
after installation, the foldable tent is in a completely unfolded
state when A and D are in a minimum distance. When the distance
between A and D increases, the foldable tent is gradually being
folded. After the foldable tent is completely folded, the distance
between A and D is the longest in the usage state, and in such a
state, the distance between A and D needs to be smaller than a sum
of the dimension of A and B and the dimension of C and D, so as to
prevent the first position-limiting pole 10 and the second
position-limiting pole 11 from being detached from each other. The
first position-limiting pole 10 and the second position-limiting
pole 11 are added to reinforce the stability between the lower
plate 12 and the tarpaulin supporting poles. Only axial movement is
allowed between the first position-limiting pole 10 and the second
position-limiting pole 11, and radial movement thereof is
determined by the size of a gap between the outer diameter of the
first position-limiting pole 10 and the inner diameter of the
second position-limiting pole 11. In theory, the smaller the gap,
the better the position-limiting effect.
[0036] As shown in FIG. 4, based on the two embodiments above, the
first position-limiting pole 10 or the second position-limiting
pole 11 of the retractable position-limiting pole is configured to
have a multi-segment retractable pole structure.
[0037] In the above embodiments, a position-limiting structure that
prevents the second position-limiting pole 11 from being detached
from the first position-limiting pole 10 is disposed on a bottom
portion of the first position-limiting pole 10 or a top portion of
the second position-limiting pole 11. The position-limiting
structure may be chosen from various known position-limiting
structures, such as a position-limiting structure employed in a
retractable pole for umbrellas. Position-limiting may be achieved
by modifying the structures of the first position-limiting pole 10
and the second position-limiting pole 11, such as modifying the
change in the diameters of the first position-limiting pole 10 and
the second position-limiting pole 11.
Embodiment 2
[0038] As shown in FIG. 5, another embodiment of the invention
provides a central reinforcing structure of a structurally
reinforced tent frame. The central reinforcing structure includes
the first tarpaulin supporting poles 5, the second tarpaulin
supporting poles 6, the supporting poles 8, the top plate 9, and
the lower plate 12. There are four first tarpaulin supporting poles
5 and four second tarpaulin supporting poles 6. The first tarpaulin
supporting poles 5 and the second tarpaulin supporting poles 6 are
hinged and fit with the top plate 9. The four second tarpaulin
supporting poles 6 and any two symmetrically arranged first
tarpaulin supporting poles 5 are connected to the supporting poles
8. The other ends of the supporting poles 8 are hinged with the
lower plate 12, and the retractable position-limiting pole is
disposed between the lower plate 12 and the top plate 9. The
structure of the retractable position-limiting pole is as described
in Embodiment 1 above and therefore details in this regard will not
be repeated herein.
[0039] In the central reinforcing structure, the directions in
which the second tarpaulin supporting poles 6 are opened are
controlled by the retractable position-limiting pole, and the force
received by the second tarpaulin supporting poles 6 is uniformly
fed back to the first tarpaulin supporting poles 5, so that the
entire structure is stably supported.
[0040] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention cover modifications and variations of this
invention provided they fall within the scope of the following
claims and their equivalents.
