FRAMEWORK FOR CAMPING TENTS AND PARASOLS WITH AN OSCILLATING
SECURE LOCKING SYSTEM
Field of the Invention
The present invention relates to tents and parasols, and specifically, for
frameworks
for tents and parasols which have a locking system.
Background of the Invention
To maintain the extensibility of the walls or parts of the cloth corresponding
to a
camping tent or parasol, a central part to which there are fixed movable arms
which in turn
receive the rods forming the structure of the compartment or camping tent per
se is
required, the following two basic fixing systems exist:
One of them comprises a rigid central part receiving arms which are
pre-established by the original design, not allowing the modification of
adding or removing arms for their use in different designs of folding
compartments.
- Another system is based on a flexible central part directly receiving
the rods forming the structure, such that in this case when the
compartment is formed, said central part is folded over itself.
Likewise, there is no option of increasing or reducing the number of
rods that can be attached to said folding system.
In summary, by means of known fixing systems, the problem they have consists
on
one hand of the structural rigidity, i.e., if one of the merge points between
arms or rods is
provided, for example, for four arms because it is required due to the design
of the folding
tent or compartment, said number is invariable and cannot be replaced with
another
having, for example, six arms when the design of the compartment is to be
changed
logically with another cloth cover; and on the other hand the impossibility of
varying the
basic structure.
Description of the Invention
The present invention relates to a framework for camping tents and parasols
with
an oscillating secure locking system based on a central part or joint which,
in combination
with a series of arms, the oscillating secure locking part and a part acting
as a cap
attaching all the parts, enables fixing as many other rods on the arms to keep
the cloth
securely extended.
The object of the invention is to achieve versatility and security of
framework for
obtaining different types of designs of both camping tents and parasols based
on the use of
one and the same type of fixing joints for the rods.
The proposed framework has been conceived to solve the problem described

CA 02745545 2011-07-07
2
above based on the different parts of the folding compartment, i.e., of the
camping tent
or parasol, the sides and roof being considered as parts, being able to remain
extended and securely allowing the folding thereof without any difficulties.
Said invention is based on the so-called "all-purpose design", including the
design, development and marketing of common products, services, systems and
environments that can be accessed and used by the greatest possible range of
users.
Specifically, the framework of the invention uses a central part with a
concentric
hole and a plurality of radial grooves intended for receiving as many other
arms such
that each groove has in its bottom area a crosspiece acting as an assembly
shaft of
each arm in order to allow the latter to take up a vertical folded position
with respect to
the central part or an extended position, those arms being assembly elements
for
respective rods which are axially inserted therein, specifically in a passage
arranged in
said arms, which rods forming the extending means and keep the corresponding
part of
the tent, either the roof or any of its side walls or rear wall, because the
front wall will
logically be made of the corresponding opening cloth forming the door for
accessing
the interior, extended. The secure locking part which is formed of as many
radial shafts
and radial grooves as the joint central has, and the oscillating radial
movement of
which allows temporarily locking the arms to prevent said structure from
accidentally
folding, is arranged before the cloth.
The cloth is fixed to the central part and the oscillating secure locking part
by
means of a stem which is rectangular in its first half and circular up to the
end thereof,
corresponding to a type of cap coupled in the rectangular hole of the
oscillating secure
locking part and in the circular hole of the central part, thus fixing the
cloth to said part,
while at the same time that stem or cap includes a head with two support
points for
being able to rotate the oscillating secure locking part and a hole or ring
for the
passage of a cord which will allow a person to pull on it and thus easily and
quickly
assemble the tent from the outside.
The described framework is compact, which allows securing and locking
multiple rods and the cloth itself to the central part.
The number of arms and therefore of rods to be assembled on the central part
will depend on the design of the tent or parasol to be formed because that
central part
has many grooves, being able to use three, four, etc., and thus situate three,
four, etc.,
rods and thereby vary the design as stated above, hence the complete
versatility of the
described framework. The oscillating secure locking system in turn covers all
the radial
grooves without taking the number of arms into account.

locking part
in its unlocking state, for unlocking the arms to allow the folding of the
arms and their
respective rods.

part from which four arms with their corresponding rods are derived, and said
arms are
in turn locked by the oscillating secure locking part.
Figure 6 shows a perspective view of an embodiment variant, in this case
forming a shade including the central part with four arms and as many other
rods, and
said arms are in turn locked by the oscillating secure locking part.
Figure 7 finally shows another perspective view of the same embodiment
variant, showing the cap fixing the cloth with the central part and the
oscillating secure
locking part.
Preferred Embodiment of the Invention
As can be seen in the mentioned figures, the framework of the invention
provided for the assembly of a folding compartment such as a camping tent
comprises
a central part (1) acting as a joint, which has a plurality of radial grooves
(2), as

CA 02745545 2011-07-07

depicted in Figure 1, the bottom of each of those radial grooves (2) being
provided with
a crosspiece acting as a shaft (3) for as many other prismatic arms (4)
positioned in
those grooves (2), which arms (4) define at their inner end a channel in the
form of a
hook (5) for being connected to the shaft determined by the different
crosspieces (3) of
the part (1), such that that assembly of the arms (4) allows the latter to
occupy a
vertical position, as depicted in Figure 3, or an extended position, as
depicted in Figure
2. Said arms can in turn be locked or not by the oscillating secure locking
part (12)
through its radial shafts (13) rotating on its central hole (14).
Specifically, such Figures 2 and 3 show the assembly of six arms (4) on the
part
(1), leaving a plurality of grooves (2) free, which means that more arms (4)
could be
assembled and the design of the tent that is sought can be varied.
The arms (4) have an axial passage or hole (6) in which a rod (7) is coupled
by
insertion such that the rods (7) are the support and extensibility means of
the cloth (8)
corresponding to the walls or roof of the camping tent, for example depicted
in Figure
4, with the particularity that the said cloth (8) is secured on the central
part (1) and the
oscillating secure locking part by means of a stem which in its initial phase
is
rectangular (9-1) like the hole(14) of the oscillating secure locking
part(12), and in its
end part is circular; said stem belongs to a cap (10) with a head from which
there
extend two planar prolongations (10-1) acting as a fixing for locking or
unlocking the
arms (4) from the oscillating secure locking part (12). Said head in turn has
a type of
ring or hole (11) for the passage of a cord which allows the pulling thereof
and
assembling the tent.
