Description
BACKGROUND
[0001] 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.
[0002] The object of the invention is to achieve complete
versatility and security of the 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.
[0003] 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: [0004] 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. [0005] 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.
[0006] 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.
SUMMARY
[0007] The proposed framework has been conceived to solve the
problem described 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] The described framework is compact, which allows securing
and locking multiple rods and the cloth itself to the central
part.
[0012] 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.

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.

embodiment variant, showing the cap fixing the cloth with the
central part and the oscillating secure locking part.
DETAILED DESCRIPTION
[0021] 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 depicted in
FIG. 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 FIG. 3, or an extended position, as depicted in FIG. 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).
[0022] Specifically, such FIGS. 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.
[0023] 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 FIG.
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.
