Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an attachment for camping
and trailering, and more particularly to a lockable top frame for
foldable tent.
[0003] 2. Description of Prior Art
[0004] In accordance with the conventional technology, a top frame
for foldable tent, as shown in FIG. 1 and FIG. 2, including a set
of foldable roof braces 1' and a set of coordinated sub-braces 5'
constructing the main frame, is typically comprised of a strut 2',
a spring 3', a spreader 4' and an end block 6', wherein a pivot hub
21' fixed on the top end of said strut 2' is pivoted radically and
respectively each sub-brace 5', the another end of said each
sub-brace 5' is pivoted on the foldable roof brace 1; said strut 2'
is put on sequentially with spring 3' and the spreader 4' pivoting
with all the foldable roof braces 1' from the bottom end, finally
fixed with the end block 6' via a bowel pin 62' at the bottom end;
approaching the bottom end of said strut 2', an elastic clamp 7' is
located, coordinating to it, said spreader 4' is possessed of a
catching notch 41 opened at the low portion for the elastic clamp
7' locking into so as to locate the spreader 4' on the strut
2'.
[0005] When tending to close the tent applying above-mentioned
structure, just need to press down the elastic clamp 7' located on
the catching notch 41' of the spreader 4' slightly to release the
lock function between the elastic clamp 7' and the catching notch
41', so that the spreader 4' slides up along with the trunk of the
strut 2' under the restoring force of the spring 3', the pivoted
roof braces 1' loosing support are closed to the center strut 2' to
finish the close operation.
[0006] In the close state, the spreader 4' is pushed upward closing
to the static pivot hub 21' under the elastic force of the spring
3' so as to locate on the high position without any extra
force.
[0007] As tending to expending the tent, just overcoming the
elastic force of spring 3', push down the spreader 4' until the
elastic clamp 7' locking into the catching notch 41', by means of
the sub-braces 5' pivoted on the static pivot hub 21', the foldable
roof braces 1' is drew up expending. But, the force exerted on the
spreader 4' by the user overcoming the long distance elastic force
of the spring 3' should be enough big, so as to bring inconvenient
to the user, especially to the shorter, in order to reach the
spreader 4', they have to stand on tiptoe, even so the spreader 4'
is still not got so that the tent is not able to be opened, hence
the open operation the tent is not convenient.
[0008] Additionally, said top frame structure has some
shortcomings, like as more parts, complicated structure, difficult
manufacture and combination.
OBJECTS AND SUMMARY OF THE INVENTION
[0009] It is therefore a main object of the present invention to
provide a top frame for foldable tent having fewer parts, simple
structure, facilitating to manufacturing and combination, easy open
operation saving labor features.
[0010] For achieving the above-mentioned object, the present
invention provides a top frame for foldable tent, which including a
set of foldable roof braces and a set of coordinated sub-braces
constructing the main frame is typically employed with a hydraulic
tappet fixed between the static pivot hub pivoting all the
sub-braces and spreader pivoting all the roof braces with both
ends, by means of the jack-up and hold-on features of the hydraulic
tappet, said spreader is pushed down and kept in the ultimate
position to bring the entire roof braces q and sub-braces to expend
out.
[0011] Said spreader has a quad low portion with crossing grooves
facilitating to exerting pushing force.
[0012] As utilizing above-mentioned project, due to substituting a
hydraulic tappet for the conventional strut, spring and end block
and locating device set upon between the static pivot hub and the
spreader, the structure has fewer parts, simple, convenient for
manufacturing and combination features.
[0013] As in open state, under jack-up and hold-on of said
hydraulic tappet, said spreader is pushed down on ultimate low
position so that the entire roof braces and sub-braces are kept in
open state such as in expending out state; as tending to close the
tent, just push up the spreader along the hydraulic tappet to bring
the entire roof braces and sub-braces to close to the center
downward, by means of tying up of a rope, the tent is closed down;
as tending to open the tent, remove away the tying rope, under the
pushing function of the hydraulic tappet, the spreader is pushed
down to bring the entire roof braces and sub-braces to expend out
until get the ultimate point and hold on, so all the open operation
is very convenient without any extra force exerting.

[0015] FIG. 2 is a perspective view showing the combination state
of the prior art.
[0016] FIG. 3 is an exploded view of the present invention.
[0017] FIG. 4 is a perspective view showing the combination state

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0019] A top frame of foldable tent provided by the present
invention is as same as the conventional to suit to foldable tent
including a set of foldable roof braces 1 and a set of coordinated
sub-braces 5 constructing the main frame.
[0020] Referring to FIG. 3, the present invention is typically
comprised of a hydraulic tappet 2 and spreader 3. Wherein said
hydraulic tappet 2 is a conventional goods, so the detail is not
described here, it typically includes a sleeve 21 and an inner rod
22. One end of the hydraulic tappet 2 (the end of sleeve 21 in
drawing) is fixed on the static pivot hub 4 pivoting with the
entire sub-braces 5, the another end of the hydraulic tappet 2 (the
rod 22 end in drawing) is fixed on the spreader 3, by means of the
jack-up and hold-on features of the hydraulic tappet, said spreader
3 is pushed down and kept in the ultimate position to bring the
entire roof braces q and sub-braces 5 to expend out.
[0021] As tending to close the tent, just push up the spreader to
bring the pivot center of the entire roof braces 1 to move up, such
as bringing the entire sub-braces 5 and roof braces 1 to
concentrate to the center, then cooperate to a rope (not shown in
drawings), the tent is tied up, as shown in FIG. 5.
[0022] As tending to open the tent, remove away the tying rope,
under the pushing function of the hydraulic tappet 2, the spreader
3 is pushed down to bring the entire roof braces 1 and sub-braces 5
to expend out until get the ultimate point and hold on, as shown in
FIG. 4, so all the open operation is very convenient without any
extra force exerting.
[0023] Said awning 3 is fixed on pivoting hub 23 of said awning
boom frame 2 with the center, and each corner is fixed on the free
end of each cornice boom 4.
[0024] In a word, as utilizing above-mentioned project, due to
substituting a hydraulic tappet 2 for the conventional strut,
spring and end block and locating device set upon between the
static pivot hub and the spreader, the structure has fewer parts,
simple, convenient for manufacturing and combination features.
