GENERAL DEFINITION OF THE INVENTION
[0084] Introduction
[0085] The invention is a structure consisting of a minimized
number of unit elements constituting the structure after assembly.
The constituting unit elements, which have the advantage of a
constant rectangular or square section along their length, include
in one of its sides at least one interior groove which provides the
invention with a plurality of options and/or functionalities that
connects with at least one of the faces of the unit element. The
structure of the invention is modular, flexible, self-supporting or
can be attached to a support, such as a wall.
[0086] The modularity of the structure allows for various
configurations and positions.
[0087] Corner connectors, in particular in the form of a cross
and/or a T allow the structure to have different sizes and shapes.
Through the originality of their structure, these corner
connectors, potentially with decorative and/or protective elements
which are added to them, also constitute an object of the
invention.
[0088] The grooves located in the unit elements allow for
positioning of the different decorative and/or functional
options/accessories, in particular options/accessories of a type
that can be retrofitted, easily or not.
[0089] The structure of the invention is easy to install, requires
no specialized labour and can be installed in a few minutes.
[0090] The corner connectors have the advantage of being
structurally reinforced and do not necessarily require the addition
of additional stays, particularly to reinforce the structure.
[0091] Several types of roofs and curtain walls and/or privacy
panels can be easily installed on the modular structure of the
invention, whether they are roofs, walls or curtains that are
permanent rigid types, flexible or retractable, manual or
automatic.
[0092] Opening and/or closing the retractable roof can, for
example, be done by turning a crank, pulling a cable or by
hand.
[0093] In the case of a roof positioned and connected with the
structure, it is possible to add to the structure an automatic roof
closing and/or opening system, according to the invention, e.g. by
cable and counterweight, elastic spring, rubber or bent fibreglass
and canvas design, whether hidden by the structure or not, or
automatically or manually locking at one of the 2 ends or both.
[0094] The curve of the roof discharges water from each side or
from just one side. A water-collection gutter can be installed
optionally. The roof, whether retractable or not, can be dismantled
in several sections for compact or maximum packing, also being an
original aspect of the invention. The caster system, with or
without ball bearings, slides the length of the structural
groove.
[0095] A side slide system which can be disassembled, provided with
rigid support rods, which can fit together or not, also part of the
invention, prevents the system from getting jammed during opening
and closing movements. The absorption by the rods and/or screws
and/or tubes can be operated in combination or independently to
correct the trajectory of the canvas.
[0096] The adjusted or permissive casters prevent the rod from
becoming locked in the groove. The guide cable, runner or rigid rod
ensures a functional and/or aesthetic straight line of the
canvas.
[0097] A first object of the invention consists of a
self-supporting structure and by unitary structural elements of the
base structure.
[0098] The self-supporting structure is comprised of profiles,
created, e.g. through aluminum extrusion. The self-supporting
structure can in an advantageous embodiment of the invention use
only one type of profile to create its entire structure, this
profile can potentially vary in terms of its length to accommodate
the use desired (feet, beams, cross-elements, reinforcements,
supports) The profile uses e.g. a square or rectangular form and
has the advantage of a groove, preferably central on each of the
large side faces of the profile.
[0099] The groove acts as a support element that can receive the
options and assemblies anticipated as additions to the structure,
being developed specifically for this use. The groove used for an
example as illustrated in the preferred embodiment below, a
T-insertion principle which allows the hardware developed as part
of the project to serve as support
[0100] Nevertheless, the necessary use of this groove does not
limit the shape, different principles of grooves can be used in the
same way with a different profile.
[0101] The structure is assembled with a corner principle
(connectors) which serve as attachment point between the main
profiles of the structure. These original connectors also
constitute an aspect of the invention. This assembly
(mechanical-welding assembly of the connectors) supports the
horizontal beams of the structure while fitting into the feet of
the structure. Assembly of the connector has the advantage of being
hidden by an ornamental cap which also maintains aesthetics, e.g.
cubic, of the structure.
[0102] The connector, which contains at least as many rods as
directions to be connected with another structural element
according to a preferred embodiment is assembled so as to orient
its rods in the X, Y and Z axial directions. The rods are then
inserted in the centre of the main profile of the structure.
According to a preferred embodiment, insertions drawn through each
of the rods have the advantage of allowing mechanical assembly of
the profiles to the connectors. Different variants of connectors
are also part of the invention, invented to allow connection of
several modular structures of the invention which would have the
advantage of using the same support point (foot). Versions with 3,
4 and 5 branches have been developed to allow multiple
arrangements, called assemblies with regard to this invention.
[0103] The modular structure of the invention, also called
principle structure on which options/accessories are grafted,
comprises a very limited quantity of parts, which facilitates
inventory management and manufacture. The profile and connectors
were developed so as to allow as many arrangements as possible
without any modification to the parts, no customized or specialized
manufacture is required for a certain type of structural
arrangement. The project is entirely modular.
[0104] A second aspect of the invention consists of a canvas for
shade and protection against rain which can be installed as an
option on the structure. The canvas is distinctive because of its
particular shape which is characterized by an arrangement of pleats
and slopes reminiscent of an accordion.
[0105] Structured, e.g. by tubes with sliding casters that are
inserted in the upper tips of the accordion as well as by flexible
rods that are installed in the lower tips, the canvas offers some
rigidity and consistency in shape. The sliding aspect of the canvas
allows it to be opened and closed, providing flexibility of
use.
[0106] In a preferred embodiment, bottom casters have the advantage
of sliding within the groove of the main extrusion profile to
provide its opening/closing movement The flexible rods inserted in
the lower tips of the canvas have guide heads, preferably of eyelet
type which slide on a taut cable so as to guide the canvas and
avoid twisting as much as possible during movement The flexible
rods inserted in the lower tips also serve to structure the canvas
with a flow curve that guides water to the sides of the structure
to prevent accumulation and ensure the structure is completely
waterproof.
[0107] Following an advantageous embodiment, the canvas can be
entirely assembled and dismantled, and following an advantageous
method assembled by inserting tubes and rods in pockets provided
for this, to then be slid into the structure which requires no
dismantling. Since the project is based on a modular principle,
options must be installable after assembly of the structure. The
sliding principle of the canvas could function following other
cable principles, such as weighted, or a crank system and benefit
from a gutter system to collect water that flows thanks to the flow
curve.
[0108] A third object of the invention consists of a
self-supporting or non-self-supporting modular structure according
to object 1 of the invention equipped with at least one retractable
or non-retractable canvas and by a self-supporting structure
according to object 1 of the invention and equipped with at least
one canvas according to object 2 of the invention.
[0109] A fourth object of the invention consists of an absorption
device permitting the smooth opening/closing of a canvas, an
"anti-twist" device. This device offers a twist margin that will
not block sliding of the guide elements in the lateral parallel
grooves of the upper frame of the modular structure. For example,
if the guide and sliding elements are casters below, blockage of
the casters is avoided when the canvas has been operated in an
uneven manner. The absorption principle is characterized by sliding
tubes at the ends of the bottom tubes on which casters are
installed, the latter permit the necessary extension of the sliding
tubes during twisting to avoid any blockage. The absorption device
is advantageously installed on the canvas prior to installation on
the structure. The advantage of the device is in its simplicity of
assembly, limited number of parts and autonomous function which
does not require particular maintenance or use. Use of the product
is intuitive for the user with simple devices for use.
[0110] This device can also be based on a different principle, such
as long screws that allow side movement of the casters and which
would not require a sliding tube. According to another embodiment
of the invention, use of larger casters offering more play once
installed in the groove of the main profile.
[0111] A fifth object of this invention is a modular structural
assembly and a modular assembly of canopies.
[0112] The invented principle of modularity allows creation of
different variants of the cover.
[0113] The concept starts with a base structure which is the ALFA
composition. This composition of tubular and connector length is
the basis of the shape and functionality of the product This
composition of parts can create infinite lengths and different bi-
and tri-directional geometric forms. All that is needed to obtain
the desired final product, is to add the desired options. Each
connector piece must advantageously be installed in a homogeneous
fashion, i.e. the connectors of the invention must preferably be
attached with the same type of nuts, but especially advantageously
at the same level. For example, the foot of a gazebo which is
attached to the ground can also be installed on the horizontal beam
and attached to a wall. For example, a foot serving as ground
anchor can also be used instead of two of the four corner
connectors, being inserted at the ends of the horizontal beams and
then anchored in a vertical support (such as a wall). Some
connectors of different shapes can be installed at any end of the
structure and therefore extend the structure itself in several
different directions.
[0114] Each option/accessory designed must be easily installed on
the modular structure both with the initial installation and as a
retrofit This means, allow in the context of the invention,
installation of a new option or a new type of roof on the base
structure without altering the components of the structure and even
without taking it apart.
[0115] Each option must be therefore conceived in this way.
Moreover, each option must be able to be shipped by courier and
therefore must be maximized for shipping to the consumer. The
product can be installed temporarily since it is very quick to
install, or permanently since the product is of commercial
quality.
[0116] A sixth object of this invention consists of tension
mechanisms for retractable canvases.
[0117] The canvas is comprised of a waterproof or non-waterproof
fabric, with aluminum rods as support, and fibreglass rods
providing shape and body to the canvas. The aluminum tubes have
casters at the ends and roll in the tube cavity. Opening of the
canvas and its closing can be done in several ways.
[0118] Side curtains or side screens: to block the view or the wind
or simply for aesthetics. Can be opened manually, automatically
with a remote, or with a press button or controlled by a cell phone
or motor.
[0119] Manual: by hand, detach the canvas and manually slide the
canvas. With the anti-blocking system, the support rods do not have
to be perfectly aligned in parallel. The rods will still slide.
[0120] Opening and closing by pulling or rolling a cable: one or
several cables can be installed in the structure and activated
using a counterweight or spring hidden or not in the structure. The
action of pulling or rolling a cord can both open and close in the
2 cases.
[0121] A seventh object in this invention consists of
multifunctional fasteners
[0122] With the goal of adapting several options to the structure,
hardware was developed specially for the structure. The attachment
system is designed to adapt to all attachment and installation
needs and defines the shape of the principal profile of the
structure. In the case of the retractable canvas, the fasteners act
as supports for the guide cable tension system.
[0123] Fasteners consist of a right-angled extrusion profile which
is installed on the outside of the groove of the principal profile
and act as a support for the options. This support is maintained by
a T-nut which is inserted into the groove and, once the assembly is
screwed, makes a one-quarter turn to become blocked in the groove,
providing pressure which fixes it in place while the screw is
tightened. The advantage gained by this principle is the
possibility of inserting fasteners into the groove of the structure
without the latter being disassembled. The fastener is also
equipped with an anti-rotation strip which allows it to stay
parallel to the groove at all times, thereby avoiding sliding from
starting.
[0124] Projected variants:
[0125] Nut without rotation which must be inserted by the ends of
the structure profiles
[0126] Permanent hardware requiring drilling in structure
profiles
[0127] Motorization: with the help of a motor, closing or opening
of the roof and/or side curtains can be done by a manual switch,
remote control or cell phone applications.
[0128] An eighth object of this invention consists of all processes
to manufacture at least one of objects 1 to 7 of the invention as
previously defined. Among these processes, in particular those
utilizing known techniques of prior art, such as riveting,
screwing, connecting, gluing, welding, clipping, etc.
[0129] A ninth object of this invention consists of the use of
objects 1 to 7 of the invention as previously defined.
[0130] As examples, but not limited to, the use of object 1 as:
temporary shelters, garden shelters, pergola, gazebo, greenhouse,
spa shelters, removable spa cover, with structure, solarium, sun
shades, rain shelters, snow shelters, shed, outdoor kitchen,
presentation kiosk, electric generator tent equipped with canvas
comprising photoelectric cells, and survival tent in particular for
the army.

[0136] the structure can be ordered in an infinite number of
configurations; [0137] the structure can be modified through
retrofitting even several years after set-up [0138] the system can
evolve over time by changing certain components; [0139] users can
change the parts themselves and make repairs as needed; [0140] for
the same model chosen by a client, dozens of versions are possible,
e.g. a rigid roof for which the run-off slope can be chosen,
components of side walls that can be transformed into handrails;
[0141] side grooves can be used for several options, such as a
lighting system with lights, water spray system, for gutters, to
hide wires, provide a guide for a slide system; [0142] universal
fasteners, combined with the structure grooves allow for the solid
attachment of any kind of product, part or other structure, they
are used to solidify the structure, hold cables, install custom
components; [0143] depending on the options chosen, the structure
can completely change style, e.g. from contemporary to Victorian,
with the same base structure; [0144] resist very strong winds,
perfect for the seashore; [0145] winter preparation of the product
is very quick, taking less than 15 minutes; [0146] can handle
intensive use such as commercial type and is refined enough for the
residential market; and [0147] depending on options, can tolerate
rain, glaze ice, and snow loads.
[0148] For example, said attachment members replace said members of
the first type or second type in alternation at said ends of the
canvas.
[0149] For example, said members of said first type are upper
members and said members of said second type are lower members.
[0150] For example, said sliding device includes two cylinders,
inserted one into the other.
[0151] For example, said sliding device includes two cylinders,
inserted one into the other so that, if one end of one of said
members of the first type is moved in an uneven fashion at its
opposite end in relation to said structure during movement of the
canvas in relation to said structure, said member of the first type
will get longer thanks to said sliding device, thereby preventing
blockage during movement of said canvas.
[0152] For example, said means of sliding or movement include
casters.
[0153] For example, said members of said second type are connected
together by at least one guide, to one of said ends of said members

generally perpendicular to said members of said second type.
[0155] For example, said guides are cables inserted into eyelets
located on said ends of said members of said second type.
[0156] For example, said support members comprise two support
members connected together by two cross members in a fashion
generally parallel to said members of the first and second type,
said support members and said cross members forming a frame that
maintains the canvas.
[0157] For example, the structure also includes at least two
vertical rods allowing retention of said frame and said canvas at a

said support members, said cross members and/or said vertical rods,
said connectors to be located at the corners of said frame and to
be sized so that the branches are hidden inside said support
members, said cross members and/or said vertical rods when they are
inserted into them.
[0164] For example, said connectors have three branches, one branch
being positioned vertically and two branches being positioned
horizontally, and said horizontal branches forming 90-degree angles
between them and with said vertical branch.
[0165] For example, said connectors have four branches, one branch
being positioned vertically and three branches being positioned
horizontally, said horizontal branches forming 90-degree angles
between them and with said vertical branch.
[0166] For example, said connectors have five branches, one branch
being positioned vertically and four branches being positioned
horizontally, said horizontal branches forming 90-degree angles
between them and with said vertical branch.
[0167] For example, the structure includes a tension mechanism
comprising a system of cables, pulleys and counterweights to permit
said movement between a folded position and an extended
position.
[0168] For example, said nut includes at least one surface allowing
engagement by friction with an object to be fastened by said means
of attachment.
[0169] For example, said support includes at least one surface
allowing engagement by friction with said object to be attached by
said means of attachment.
[0170] For example, said support includes an eyelet to receive a
coupling element
[0171] For example, said coupling element is a hook, a screw and a
nut or a snaphook.
[0172] For example, said means includes, at least one removable

support
[0173] For example, said support defines a notch to hold and
support an object
[0174] For example, said strip includes at least one central part
and at least one fin sized to be next to a lateral part of said
support.
[0175] For example, said strip includes at least one central part
and two fins located at two opposite ends of said central part,
said fins forming a 90-degree angle with said central part and
sized to be next to a lateral part of said support.
[0176] For example, said support has an L shape.
[0177] For example, said first diagonal is shorter than said second
diagonal.
[0178] For example, said nut of said means of attachment is sized
to allow a 90 degree rotation in only one direction in said groove
when the screw is inserted into the nut and the nut is inserted
into said groove.
[0179] For example, the assembly also includes a canvas described
herein
[0180] For example, the assembly is also comprising a canvas
described herein, said canvas to be maintained in said extended
position in said frame through said device to be attached in a
removable fashion to at least one means of fastening to be inserted

[0229] Structure (23) and Unit Elements (32) of the Base
Structure
[0230] Referring to FIG. 1, the self-supporting structure (23) is
comprised of profiles (32) created through aluminum extrusion. The
structure uses a single profile to constitute its structure, the
profile varies in length to accommodate the use desired (feet,
beams, cross members, reinforcement, support). The profile (32)
uses a square form comprised of a central longitudinal groove (17)
on each of the faces of the resulting extrusion. As illustrated in
FIGS. 29 and 30, the groove (17) acts as a support element that can
hold the options and assemblies anticipated as additions to the
self-supporting structure (23), the latter was developed
specifically for this use. The groove (17) currently uses a
T-insertion principle which allows the hardware developed with
regard to the project to serve as support. Nevertheless, the
necessary use of this groove does not limit its shape, different
principles of grooves could be used in the same way with a
different profile, for example, those represented in FIG. 29.
[0231] The structure (23) is assembled with a corner principle
(connectors) (25-26-27) which serve as attachment points between
the main profiles (32) of the structure (23) (see, for example,
FIGS. 1 to 6B, 8, 9, 11, 16A to 19B, and 31). This
mechanical-welding assembly of the connectors may be composed with
the aluminum extrusion profiles (28) as illustrated in FIGS. 17A
and 17B, in order to support the horizontal beams (support members
and cross members) (14) of the structure while fitting into the
feet (vertical rods) (15) of the structure (23). For example,
assembly of the connector (25-26-27) is hidden by an ornamental
cube (29) which also maintains the cubic aesthetic of the structure
(FIGS. 17A and 17B). The connector (25-26-27) is assembled so as to
orient its rods (28) in the X, Y and Z axial directions. The rods
are then inserted in the centre (16) of the main profile (32) of
the structure 23). For example, as illustrated in FIG. 17A,
threaded insertions (31) can be present in each of the rods (28),
which then allows a mechanical assembly of the profiles to the
connectors using a screw. Different variants of connectors were
developed to allow connection of several structures using the same
support point (foot). Versions or assemblies with 3 (25), 4 (26)
and 5 (27) branches have been developed to allow multiple
arrangements.
[0232] The principal structure (23) comprises a very limited
quantity of parts which facilitates inventory management and
manufacture. The profile and connectors were developed so as to
allow as many arrangements as possible without any modification to
the constituent parts, no customized or specialized manufacture is
required for a particular type of structural arrangement. The
structures and the assemblies of the invention are entirely
modular. For example, structure members (support and cross members)
as well as feet (vertical rods) have an identical profile.
[0233] The structure is modular and can be used to support several
objects, in particular a canvas for shade and rain protection, as
described in the present application. Other types of canvas are
envisaged, e.g. a flat or simple canvas for use as shelter against
the sun (see for example FIG. 10).
[0234] Description of the Canvas (41)
[0235] Referring now to FIGS. 1, 2, 7-9 and 11, the shade and rain
protection canvas (41) can be easily installed on the structure
(23) as an option. The canvas (41) is distinctive because of its
particular shape which is characterized by pleats (8) and slopes
(9) reminiscent of an accordion principle (see for example FIG.
20). Referring to FIG. 22, the canvas can be, e.g. structured in
the frame by tubes (members of the first type) (35) with sliding
casters (38) which are inserted in the upper tips (12) of the
accordion as well as by flexible rods (members of the second type)
(45) which are installed in the lower tips (13). This particular
provision provides the canvas with a certain rigidity and
consistency of shape. The sliding aspect of the canvas (41) allows
it to be opened and closed, providing flexibility of use. Bottom
casters (38) slide in the groove (17) of the main extrusion profile
(32) to allow the opening/closing movement (see FIG. 22). Referring
to FIG. 14, the flexible rods (members of the second type) (45)
inserted in the bottom tips (13) of the canvas (41) have guide tips
(46) of eyelet type which slide on a taut cable (or a guide) (51)
so as to guide the canvas (41) and avoid twisting as much as
possible during movement The flexible rods inserted in the bottom
tips also serve to structure the canvas (41) with a flow curve that
guides water to the sides of the structure to prevent accumulation
and ensure the structure is completely waterproof. FIG. 32B
illustrates the distance (A) between two lower tips of the canvas,
the height (B) between an upper tip and a lower tip of the canvas
(41), as well as the angle (C) between the two slopes generated by
a fold. FIG. 33 illustrates the flow curve (D) which extends the
entire width (E) of the canvas (41).
[0236] The canvas (41) can be entirely assembled and dismantled, it
is assembled by inserting rigid tubes (35) and flexible rods (45)
in pockets provided for this, to then be slid into the structure
(23) which requires no dismantling. Since the project is based on a
modular principle, options must be installable after assembly of
the structure (41). The sliding principle of the canvas (41) could
function following other cable principles, such as weighted, or a
crank system and benefit from a gutter system located at the ends
of the bottom tips (13), which redirects water there thanks to the
flow curves created by the flexible rods (45) to collect water.
[0237] Absorption Device (36)
[0238] Referring now to FIGS. 22 and 23, to allow for smooth
opening/closing of the canvas (41), an "anti-twist" device was
developed. This device offers a margin of twisting which does not
block sliding of the bottom casters (38), if the canvas (41) has
been operation in an uneven manner. The absorption principal is
characterized, e.g. by sliding tubes (36) at the ends of the bottom
tubes (35) on which casters (38) are installed through threaded
tips (37) and screws (39). These sliding tubes (36) allow the
necessary extension of tubes (35) during twisting to avoid any
blockage (see in particular FIGS. 23A, 23B and 32C). The absorption
device, comprising elements 36 to 39, is installed on the canvas
(41) prior to installation on the structure (23). One of the
advantages of the absorption device is in its simplicity of
assembly, low number of parts and autonomous function which does
not require particular maintenance or use. Use of the product is
intuitive for the user with simple devices for use.
[0239] This absorption device can, according to a variant of the
invention, be based on one of the different mechanical principles,
such as long screws (39) that would allow side movement of the
casters (38) and would not require a sliding tube (36a), as shown
in FIGS. 24B and 24B.
[0240] Another principle explored with success was the use of
larger casters which would offer more play once inserted into the
groove of the main profile, as illustrated in FIGS. 25A and
25B.
[0241] Modularity
[0242] The very great modularity of the invention structures allows
for the creation of different varieties of shelters.
[0243] The concept starts with a base structure (23) which is the
ALFA composition. This composition of tubular lengths (32) and
connectors (25-26-27) is the basis of the shape and functionality
of the project.
[0244] This composition of parts can create infinite lengths and
different geometric forms. To obtain the desired final product
adding the desired options is sufficient Each connector piece
(25-26-27) must have homogeneous installation, i.e. they must be
attached with the same bolts at the same level. For example, at the
foot of a gazebo (33) which is attached to the ground, can also be
installed on the horizontal beam (14) and attached to a wall (11).
Some connectors of different shapes can be installed at any end of
the structure and therefore extend the structure itself in several
different directions (see for example FIGS. 11, 18A, 18B, 19A and
19B).
[0245] Each designed option must be easily installed on the
structure (23) both with the initial installation and as a
retrofit. This means permitting installation of a new option or a
new type of roof on the base structure, without altering the
components of the structure (23) and even without taking it apart.
Each option and complementary accessory is designed with this
purpose. Moreover, each option and each accessory must
advantageously be able to be shipped by courier and therefore must
be maximized to reduce costs and complexity of installation for the
consumer. The product can be installed temporarily since it is very
quick to install and dismantle. It can also be installed
permanently, in particular because the product is of commercial
quality.
[0246] The vertical and horizontal members [see, e.g. feet (15) and
beams (14)] can be identical. Thus, the structure members, support
members cross members and vertical rods can be used
interchangeably. In fact, all these parts can be identical and thus
a given piece can be used either as a support member, or as a cross
member or as a vertical rod.
[0247] Tension Mechanisms for the Retractable Canvas (41)
[0248] The retractable canvas (41) is comprised of a waterproof or
non-waterproof fabric, with aluminum rods as support The flexible
rods (members of the second type) (45) in fibreglass provide shape
and body to the canvas (41). The aluminum tubes (members of the
first type) (34) have casters (38) at the ends and roll in the
groove (17) of the extrusion (32). Opening and closing of the
canvas can be done in several ways. As side curtains or side
screens (6) (see, e.g. FIG. 31): to block the view or the wind or
simply for aesthetics. Can be opened manually, automatically with a
remote, or with a press button or controlled by a cell phone or
motor.
[0249] Operation can be manual: with one or two hands, the operator
can detach the canvas (41) and slide it (41) manually, as
illustrated in FIG. 2, in which the canvas is in a folded position.
With the anti-blocking system (36) the rods (support members) (35)
do not have to be perfectly aligned in parallel. The rods will
still slide. Several options are possible to keep the canvas in the
extended position. For example, attachment tubes (47) positioned at
each end of the canvas can include a device, for example hooks, to
attach the canvas to the cross members. Hooks can be attached to
fasteners that are described herein. Each fastener, being attached
in a groove of a cross member, is comprised of a support which
includes an eyelet in which the hook has been inserted (e.g. see
FIG. 38--a hook or snaphook has been attached in an eyelet).
[0250] In another example, the attachment tube does not include a
device but is secured to the cross members with a clip held by the
fastener (22), which is in turn attached to the groove of the cross
members (see for example FIGS. 36 and 37).
[0251] Opening and closing by pulling or rolling a cable: For
example, referring to FIG. 12, one or more cables (10) can be
installed in the structure (23), either by using the grooves of the
profiles (17) or the centre of the profiles (16) (see FIG. 30) to
run the cable. An external principle of the pulleys could also be
added to the system and operated using counterweights (43)
positioned inside profiles (32), grooves (17) or, again, exterior
to the structure and/or springs (44) hidden or not in the structure
(23) (see FIG. 13). The action of pulling or rolling a cord can
both open and close in the 2 cases.
[0252] Fastener (22)
[0253] With the goal of adapting several options to the structure
(23) invention hardware was developed specially for the structure.
Referring to FIGS. 26, 27 and 34 to 38, the attachment system (or
means of fastening) (22) is designed to adapt to all attachment and
installation needs and defines the shape of the principal profile
(32) of the structure (23). In the case of the retractable canvas
(41), the fasteners (22) can act as supports for the guide cable
tension system (51).
[0254] Fasteners can be comprised of an extrusion profile, for
example with a right angle (19), which is installed outside of the
groove (17) of the principal profile (32) and which acts as a
support for the options/accessories. For example, the fastener (3)
can include a notch (5) to hold and support an object, such as an
attachment member (47) of a canvas (FIGS. 35 to 37). For example,
it is possible to insert a nut washer (4) between the screw and the
nut (FIG. 35B). For example, the fastener (22) can include an
eyelet (55) in which can be inserted a coupling element, e.g. a
hook which can be connected to the canvas in order to support a
flat canvas (FIG. 38).
[0255] This support is maintained by the T-nut (18) which is
inserted inside the groove (17) (see FIG. 27A) and, once the
assembly (means of attachment) (22) is screwed, makes a one-quarter
turn to become blocked in the groove (17), providing pressure which
fixes it in place while the screw is tightened (see FIG. 27B). The
nut (18) includes a serrated surface allowing engagement by
friction with an object to be fastened by the means of attachment
The support (19) includes a serrated surface allowing frictional
engagement with an object to be fastened by means of the attachment
FIGS. 34A and 27B illustrate more particularly the proportions of
the nut (18) next to a groove in a profile (32). The nut (18) is of
a generally rectangular shape and has four corners. Two corners
connected by a first diagonal are rounded and two corners connected
by a second diagonal form right angles. The first diagonal includes
a length G which is less than the second diagonal. The dimensions
of the nut allow insertion in the groove, between the two edges of
the groove (acting as retaining lips for the screw), since one of
its sides is narrow, of a smaller dimension than the distance
between the two edges. The groove comprises a width F which has a
dimension approximately similar to the longest side H of the nut,
greater than the length of the first diagonal connecting the
rounded corners G but less than the length of the second diagonal
connecting the right-angle corners. Thus the nut can be turned no
more than 90 degrees only in one direction and then becomes blocked
in the groove. The nut is then blocked since the length H prevents
additional rotating due to its size and the nut is therefore
blocked by frictional engagement with the groove.
[0256] The advantage gained by this principle is the possibility of
inserting fasteners (22) (means of attachment) in the groove (17)
of the structure (23) without the latter being disassembled.
[0257] For example, fasteners can be inserted in the grooves of the
support members, cross members, as well as the vertical rods.
Moreover, there is no need to screw anything at all directly into
the profile (i.e. a support/cross member or a vertical rod).
[0258] The fastener (22) is also equipped with an anti-rotation
strip (20) which allows it to stay parallel to the groove (17) at
all times, thereby avoiding sliding from starting. The
anti-rotation strip (20) includes one central part and at least one
fin, preferably two fins located on both sides of the central part,
forming a 90-degree angle with the central part The fins are next
to the two side parts of the support, as illustrated in FIGS. 26A
and 26B.
[0259] Upon installation of the means of attachment (22) in groove
(17), the means of attachment (22) is pre-assembled, meaning that
the screw (21) is inserted in the opening (52) of the strip (20),
then in the opening (53) of the support (19) and finally in the
threaded opening (54) of the nut (18). The nut (18) and a part of
the screw (21) are then inserted in the groove (17) by placing the
nut (18) parallel to the direction of the groove (17) (see FIG.
27A). The screw is then tightened, which potentially caused the
90-degree rotation of the nut which has tightened the lips or edges
of the groove (17) (see FIG. 27B). A user may easily do all this
and installation does not necessarily require the use of two hands
by the user. Indeed, the user can then fasten an attachment (22) in
a groove (17) without being obliged to insert fingers into the
groove or being obliged to insert another object to hold the
attachment (22) during installation since the configuration of the
fastener allows the user to use one hand to quickly install it by
making a single quarter turn (90-degree rotation) in order to
fasten the attachment (22) to the ends of the groove (17). The
configuration of the attachment (22) is called "quick fit".
[0260] Several varieties of fasteners (22) providing the same
function are envisaged: nut without rotation which must be inserted
by the ends of the structure profiles or permanent hardware
requiring a piercing of the structure profiles.
[0261] For example, fastener (22) may be used to attach guide
cables. In this case, it is possible to attach two fasteners (22)
in the grooves of the feet of the structure (or vertical rods) at a
height corresponding to that of the bottom tips of the canvas.
[0262] For example, two fasteners can be attached in the grooves of
the structure fee (or vertical rods) at a desired height in order
to install a device to hold a curtain support.
[0263] Referring again to FIG. 26, several types of screws (21) are
envisaged. The screw has a threaded rod (not indicated in FIG. 26B)
and a head, for example a head comprising a six-sided opening (for
an Allen key).
[0264] Motorization: With the help of a motor, closing and opening
of the roof and/or side curtains can be done by a manual switch,
remote control or cell phone applications.
[0265] Possible Variations of the Principal Profile of the
Structure
[0266] The principal extrusion profile of the structure (32) was
developed as part of the project to permit adaptation to different
needs of the project Its symmetrical form is justified by the
modular aspect which is required of the structure (23), like the
insertion grooves (17) which are present on each face. However,
while the current profile fulfils its requirements, it could still
have different shapes which would respond to the needs of the
structure (23).
[0267] The centre of the extrusion (16) currently uses a square
shape which holds the connector rods (28), its form is defined by
that of the connectors (25-26-27). However, the connectors could
use circular branches (28), thereby causing the centre of the
profile (16) to have a circular or other shape, as illustrated in
FIG. 29.
[0268] Referring again to FIG. 29, the groove (17) on each face of
the profile (32) can also be subject to different variations in
size, proportions and even form. Since this form acts as a support
to the fasteners (22) its form depends on that of the T-nuts (18)
which can also change. The primary aspect of the groove are the
edges which act as retaining lips for the nut (18) as well as its
opening, which must allow for the latter to be inserted. However,
the dimensions and proportions of the groove (17) and their edge
can change yet maintain their function, certain aspects of the
groove (17) such as the bevels or the rectangular shape can also be
modified as long as the retaining edges are still present.
[0269] Various aspects of the extrusion (32) were established
according to technical or manufacturing constraints or for solidity
or the price of raw materials. Therefore, certain thicknesses could
vary to increase/reduce solidity and manufacturing costs, the shape
of corners could also change to accommodate certain equipment The
profile principal is based on its functioning not its shape and
dimensions.
[0270] This invention was described above in reference to a
preferred mode of creation of the invention. Of course, the
production which has just been described is only for the purposes
of illustration and is in no case restrictive, various
modifications can be made to the different objects of which it is
comprised without going beyond the scope of this invention.
