[0001] The present invention relates to a box for roll-up awnings.
[0002] In order to cover the openings of buildings, such as doors, windows, skylights and
the like, it is known to use awnings constituted by a covering sheet which can be
rolled up onto a roller which is accommodated rotatably in a respective box arranged
above the opening. The sheet is associated by means of its upper end with the roller
and is connected by means of its lower end to a transverse bar for grip on the part
of the user; each one of the two lateral edges of the sheet can be guided or not slidingly
by an appropriate rail of a provided guiding assembly associated with the opening
to be covered. Such guiding assembly notoriously comprises two vertical posts which
have a substantially U-shaped transverse cross-section and are fixed so as to face
each other on the open side of said U-shape. In a practical example of installation,
the posts are fixed to the internal sides of an opening by way of appropriate screw
means inserted in corresponding holes.
[0003] If the covering sheet rolls up incorrectly, or if a foreign object becomes interposed
between two successive layers of rolled-up sheet, it is necessary to work inside the
box in order to remove the fault.
[0004] Further, in order to perform operations for replacing the sheet or the actuation
device and for modifying and adjusting the stroke limit of the roll-up action, it
is essential to access effectively the inside of the box.
[0005] Currently commercially available boxes require the disassembly of fixed parts in
case of maintenance. Moreover, it must be noted that in order to allow such disassembly
and reassembly, it is necessary to provide appropriate slots in the closure housings
which will be removed, such slots allowing to remove the housings without having to
also disassemble the actuation element (generally a winch, which can be actuated by
means of a rod provided with a crank at one end and with a hook at the other).
[0006] An example of a box with with roll-up awning that can be disassembled is available
from the document
AT 399 200 B.
[0007] The aim of the present invention is to obviate the above-mentioned shortcomings and
meet the mentioned requirements, by providing a box for roll-up awnings which can
be opened easily for maintenance without the aid of specific tools.
[0008] Within this aim, an object of the present invention is to provide a device which
is simple, relatively easy to provide in practice, safe in use, effective in operation,
and has a relatively low cost.
[0009] This aim and this and other objects that will become better apparent hereinafter
are achieved by a box for roll-up awnings, according to the present invention that
has the features of claim 1.
[0010] A method for fixing a laminar element to a box for roll-up awnings, according to
the present invention, which has the steps of claim 9.
[0011] Further characteristics and advantages of the present invention will become better

Figure 12 is a perspective view of a closure plug of a box for roll-up awnings according
to the invention.
[0012] With reference to the figures, the reference numeral 1 generally designates a box
for roll-up awnings.
[0013] The box 1 for roll-up awnings comprises a fixed frame 2 for the longitudinal support
of a roller 3 for rolling up the awning: the roller 3 is supported so that it can
rotate about its own axis of symmetry, so that by rotating it allows to roll up and
and unroll the awning.
[0014] Inside the box 1 an actuation element 4 is also provided, which is associated with
the roller 3 by way of a transmission assembly; the actuation element can be a hand
winch 4a, the rotating sprocket of which is engaged on a head of the roller 3, rigidly
coupling its movements (in this case, manual actuation performed by means of an appropriate
rod equipped with an end crank, not shown in the figure, which engages in the hand
winch 4a), or a small electric motor 4b, which is coupled to the roller 3 in order
to drive its movement and is constituted by a motor body 5.
[0015] At the front, the box 1 has a sort of closure housing, which is constituted by a
laminar element 6 provided with appropriate longitudinal folding lines, which form
a substantially L-shaped profile thereof.
[0016] The laminar element 6 is provided, at the upper anchoring end 7, with a crest 8,
which is perpendicular to its profile and is directed toward the inside of said profile.
[0017] Below the end 7 there is a flat portion 9, whose height is substantially equal to
the total height of the entire box 1; such portion in turn ends by connecting to a
bottom 10, which is also flat and substantially perpendicular to the portion 9.
[0018] At the connection between the portion 9 and the bottom 10 there is a rib 10a, which
is directed toward the inside of the L-shape (laminar element 6) and perpendicular
to the portion 9 and mates with a respective protrusion provided inside appropriate
end closure means, described subsequently, and further helps to stiffen the laminar
element 6.
[0019] The fixed frame 2 is provided with an upper front seat 11, whose shape is conveniently
complementary to the shape of the upper anchoring end 7 of the lamina 6; the profile
has a first substantially curved portion 12, which is connected to the frame 2 at
an abutment border 13 and ends by blending with a second flat portion 14, which is
substantially parallel to the upper face 15 of the frame 2; at the end of the second
portion 14 there is a connection to a third angular portion 16 (the surface 17 connected
to the second portion 14 is substantially perpendicular to the portion 14).
[0020] The frame 2 has, at its upper face 15, substantially perimetric bands 18, which are
intended for detachable interlocking in a respective bracket 19, which is coupled
to a fixed supporting structure by means of suitable connecting elements (screws 20
in the figure). The perimetric bands 18 are also provided on the plugs 21.
[0021] The box 1 can be closed at its ends by means of appropriately provided plugs 21.
[0022] Each one of the plugs 21 is constituted by a flat face 22, which is provided with
a perimetric lateral edge 23 along which protruding interlocking means 24 are distributed
proximate to respective receptacles formed by protrusions 25 which correspond thereto
on the frame 2 and facilitate assembly and centering operations (in order to ensure
the stability of the connection, screws 24a are provided).
[0023] In a preferred embodiment, the plug 21 can be made of plastics in order to avoid
any machining on aluminum, which is demanding and can compromise the paintwork with
aesthetic problems. Accordingly, the holes are provided only on the plastic plug 21.
[0024] The face 22 and the edge 23 delimit a compartment for accommodating the actuation
element 4.
[0025] In the case of a box 1 for awnings with manual actuation, the edge 23 has a lower
opening 26 for the passage of a tab 27 for the manual actuation of the hand winch
4a, in which an appropriate rod, provided with an end crank not shown in the figure,
engages.
[0026] In the case instead of a box 1 for awnings with automated actuation, the edge 23
generally has only a small opening for the passage of at least one electric power
supply cable (not shown in the figure and in any case not essential, since the power
supply cables can also be received directly through holes provided in the frame 2)
of the electric actuation motor 4b.
[0027] In any case, the edge 23 is interrupted in its front portion, and the limits of the
edge 23 at the interruption form respective seats 28 for the ends of a removable closure
flap 29. The presence of the flap 29 allows to access easily the actuation element
4 for cleaning or maintenance operations.
[0028] Once the laminar element 6 has been fitted in the frame 2, the upper end 7 rests
on the abutment border 13 and the crest 8 rests within the track 30 delimited by the
two surfaces of the third angular portion 16.
[0029] In these conditions, the lower end 31 of the lamina 6 is located proximate to a lower
cross-member (not designated by a reference numeral in the figure) of the frame 2.
[0030] In order to fix the laminar element 6 to the frame 2, it is convenient to follow
the operations defined by means of Figures 6 to 11. First of all, it is necessary
to align horizontally the upper end 7 of the laminar element 6 with the upper front
seat 11 of the frame 2 (Figure 6) and then insert the end 7 in the seat 11 until the
head 32 of the end 7 rests on the connecting corner 33 between the first portion 12
and the second portion 14 (Figure 7).
[0031] At this point, it is necessary to lower the laminar element 6, turning it instantly
first around a resting point on the second portion 14 and then around the head 34
of the crest 8 which rests within the track 30 until the head 32 of the end 7 rests
against the abutment border 13.
[0032] The operation of the invention is as follows: once the bracket 19 has been fitted
by means of the screws 20, it is necessary to arrange the lateral plugs 21 by coupling
the corresponding actuation element 4 to the roller 3.
[0033] Assembly is completed by fixing with an interlocking coupling the frame 2 to the
bracket 19, which internally accommodates the roller 3 on which the awning is wound
and by arranging the laminar element 6 as described above.
[0034] Advantageously, the box 1 for roll-up awnings according to the invention can be opened
easily for maintenance without the aid of specific equipment.
[0035] Conveniently, the lateral plugs 21 also can be opened by removing the flap 29, thus
allowing easy maintenance of the actuation elements 4.
[0036] It has thus been shown that the invention achieves the intended aim and object.
[0037] The invention thus conceived is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims.
[0038] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
