7. The frame of claim 6, wherein the rod sections telescope.
8. The frame of claim 1, wherein the first sub-frame and second
sub-frame exhibit a V-shape in the unfolded state.
9. The frame of claim 1, wherein the first upright rod is adjacent
the first top rod and the third upright rod in the folded
state.
10. The frame of claim 1, wherein the first, second, third, and
fourth top rods are flexible and bent in the unfolded state and
relatively straight in the folded state.
Description
FIELD
[0001] The utility model relates to outdoor leisure products, and
particularly to a frame for a tent.
BACKGROUND
[0002] Tents have various forms. For example, there are large tents
and small tents. Besides, there are square, circular and hexagonal
tents. The tent primarily consists of a tent cloth and a tent frame
for supporting the tent cloth. The common tent frame generally
consists of several groups of supporting rods for connecting top
rods, and the top rods form a top support structure. However, the
well-known tents suffer from a general drawback in that they
usually are relatively complicated in structure. Several groups of
rods are required to support the tent cloth. It is difficult and
time-consuming to put up the support structure, and the production
cost is also increased.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] FIG. 1 is a perspective structural view illustrating an
unfolded state of the utility model;
[0004] FIG. 2 is a structural view illustrating a partially folded
state of the utility model;
[0005] FIG. 3 is a structural view illustrating a half folded state
of the utility model;
[0006] FIG. 4 is a structural view illustrating a further folded
state of the utility model; and
[0007] FIG. 5 is a structural view illustrating a fully folded
state of the utility model.
DETAILED DESCRIPTION
[0008] The utility model will be elucidated in detail hereinafter
by referring to specific embodiments, so as to provide further
explanations for the technical solution of the utility model.
DETAILED DESCRIPTION
[0009] FIG. 1 depicts a frame for a tent. The frame includes two
collapsible, arched sub-frames 1 interconnected at their respective
ends by a pair of bottom pivoting seats 2. The frame can support a
cloth (not shown) that defines a tent interior. In order to support
the cloth with a relatively large area, the cloth can be connected
to the inside or outside of the space enclosed within sub-frames 1.
The cloth at both sides of the frame can be pulled to expand and
separate sub-frames 1, and can have a bottom fixed to the ground so
as to form a standing and unfolded tent. The tent cloth can be
provided with a fastening buckle which is connected and fixed to
the supporting frame rod. The tent cloth can be provided with a
hook (not shown) at the bottom for fixing the tent cloth to the
ground, As a result, once the tent cloth is supported by the
supporting sub-frames 1 and the tent cloth is pulled to expand and
fix, a three-dimensional tent is achieved.
[0010] In order to fold and expand the tent frame, referring to
FIGS. 1-5, each supporting sub-frame 1 comprises two upright rods
11 and top rods 12 which are movably connected to top ends of the
upright rods 11 respectively. The upright rods 11 and the top rods
12 are connected by a one-way connecting piece 13 which has an
angle limit and is folded upward. The two top rods 12 are connected
by a one-way connecting piece 14 which has an angle limit and is
folded downward. Here, the upright rods 11 can have a telescopic
sleeve structure to increase the height of the tent. The top rods
12 can be flexible rods. As a result, the top rods can exhibit an
arched top when it is expanded between two upright rods 11, so that
the top of the tent is curved and the top surface of the tent is
fuller.
[0011] The lower end of each of the two upright rods 11 is
connected to bottom pivoting seat 2, and the two sub-frames 1 are
arranged side-by-side and can be folded in parallel. When the tent
is in use--the frame is unfolded--sub-frames 1 are expanded to form
a V shape, as shown in FIG. 1. The bottom of each upright rod 11 is
connected to one of the bottom pivoting seats 2, and each pivoting
seat 2 is provided with two pivoting ports for connecting the
upright rods accordingly.
[0012] To collapse the frame, upright rods 11 are telescopically
collapsed. The top rods 12 and the upright rods 11 which have been
folded at both sides can be further bent downward simultaneously to
fold inward, and can be drawn close to each other and then folded.
Further, under the action of the one-way connecting piece 13, each
upright rod 11 is bent upward and folded to the top rods 12, thus
the tent frame can be folded as a whole with minimum volume, as
shown in FIGS. 4-5. Since the supporting sub-frames 1 are bent
inward and then folded together in a step by step manner, it is
possible to avoid stacking the tent cloth in a disorderly manner
and to expand the tent cloth in an orderly manner. The one-way
connecting pieces 13 and 14 further have an angle limit. Thus, the
sub-frames 1 form a certain angle when expanded, so as to support
the tent. The one-way connecting piece 14 can further be provided
with a snap button, which makes it convenient to fold the two top
rods 12.
[0013] In the tent frame of the utility model, since two groups of
supporting frame rods--sub-frames 1--are combined to form the tent
frame, the tent frame is simple in the whole structure, and is easy
to fold and use. Besides, the tent cloth can be directly integrated
with the frame, so that the tent cloth can be put up by expanding
the supporting frame rod and pulling the tent cloth at the same
time. The tent frame can also be folded conveniently and fast into
a small volume, which makes it convenient to collect and carry.
[0014] The above embodiments and drawings do not intend to limit
the product form of the utility model. The modifications and
variations that a skilled artisan may make to these embodiments
still fall within the scope of the utility model.
