Description
TECHNICAL FIELD
[0001] The present invention relates to a tent.
BACKGROUND OF THE INVENTION
[0002] Conventionally a tent frame is often made in a type which
requires assembling. During use all parts have to be assembled on
the spot, which is inconvenient for the outdoor operation,
especially in rainy days and at night.
SUMMARY OF THE INVENTION
[0003] The purpose of this invention is to provide an integral
tent, which is as convenient, light, handy, and easy to assembly
and disassembly as a folding umbrella.
[0004] The present tent includes a tent frame and a canvas which
covers the periphery of the tent frame, characterized in that the
tent frame includes an umbrella-type frame for supporting the
canvas and includes a spreader frame for spreading and opening the
umbrella-type frame, the spreader frame being positioned in an
inner side of an upper part of the umbrella-type frame, the
umbrella-type frame including an upper central head in the middle
and ribs distributed evenly around the upper central head and
hinged to the upper central head, the spreader frame including a
lower central head in the middle and spreaders distributed evenly
around the lower central head and hinged to the lower central head,
outside ends of the spreaders being hinged to upper parts of the
ribs.
[0005] When the apparatus is pitched, the spreader frame is pushed
upwards to open the umbrella-type frame, and the canvas attached to
the umbrella-type frame is opened accordingly. Because of tension
of the tent, the umbrella-type frame will be arched after it is
opened to some extent. When not in use, the tent is closed like an
umbrella. Thus, the present tent is substantially advantageous in
that it is light, handy, and easy to handle, and occupies less
space.

[0006] FIG. 1 is a schematic diagram illustrating a structure of
the present invention;
[0007] FIG. 2 is a schematic diagram illustrating a partial
structure of the present invention when it is opened;
[0008] FIG. 3 is a schematic diagram illustrating a partial
structure of the present invention when it is dissembled; and
[0009] FIG. 4 is a schematic diagram illustrating a hinge joint of
the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0010] Referring to the attached figures, the present invention
relates to a tent including a tent frame and a canvas which covers
the periphery of the tent frame, characterized in that the tent
frame includes an umbrella-type frame for supporting the canvas and
includes a spreader frame for spreading and opening the
umbrella-type frame, the spreader frame being positioned in an
inner side of an upper part of the umbrella-type frame, the
umbrella-type frame including an upper central head 1 in the middle
and ribs 2 distributed evenly around the upper central head 1 and
hinged to the upper central head 1, the spreader frame including a
lower central head 3 in the middle and spreaders 4 distributed
evenly around the lower central head 3 and hinged to the lower
central head 3, outside ends of the spreaders being hinged to upper
parts of the ribs.
[0011] The foregoing-described upper central head includes
connectors 5 for hinging to the ribs, and the lower central head
includes connectors for hinging to the spreaders.
[0012] The foregoing-described connecters have grooves at inner
surfaces. The foregoing-described central head includes a base and
a cap covering the base. The base includes racks at its outer
surface. The grooves of the connectors are closely coupled with
outsides of the racks. The upper end of the connector is fastened
to the skirt part of the cap, and the lower end of the connector is
fastened to the rim of the base. On the top of the cap of the lower
central head, there is a protrusion 6, which can be inserted into
an opening at the base of the upper central head. When in use,
since the connectors are coupled to the racks of the central heads,
the number of the connectors can be adjusted according to the size
of the tent, which in turn changes the number of the spreaders.
[0013] There are four openings on the top of the
foregoing-described upper central head, which are used by cords 7.
In the middle part of the base of the foregoing-described lower
central head, there are two movable blocks 8 for winding the cords.
One end of the cords is fixed on the upper central head, while the
other end is extended to the outside via the openings of the upper
central head after winding around the movable blocks (see FIG. 3).
The use of double movable blocks may greatly reduce the force
needed to pull the cords tight.
[0014] The umbrella-type frame and the spreaders described above
are composed of short bars connected to each other for easy
folding. One connector 9 is composed of two short joints hinged to
each other. One of the joints includes a notch 10 at its hinging
end. A sliding cover 11 is around the other joint for positioning.
The sliding cover includes a convex button 12 at its head for
inserting into the notch. The sliding cover includes a spring 13
for fixing the sliding cover and pressing the convex button into
the notch, which is positioned at the junction of the tail of the
sliding cover and the short bar.
[0015] The foregoing-described connector is positioned at the
junction of the rib and a short ground supporting bar. The upper
short bar of the rib is hinged by a connector 14. Boards are
positioned on the inner side of the connector to prevent the ribs
from bending inward.
