[0001] The present patent application for industrial invention relates to a folding banner
support assembly. The reference sector is the advertising sector, with special reference
to the installation of advertising bills attached to a support, such as for example
a pole.
[0002] Banners are known, which are usually made of flexible plastics and provided with
a front side and/or a back side whereon an advertising message is printed.
[0003] The banner is usually provided with two slots, which are respectively obtained on
the lower edge and on the upper edge. Each slot houses a rigid rod in order to support
the banner.
[0004] The banners are usually positioned on a support, such as for example a pole, in order
to increase the visibility of the banner. In particular, the banner is connected to
the support by means of connection means, in such manner that the banner is tensioned
and visible.
[0005] More precisely, said connection means generally comprise two metal brackets with
circular shape, which are tightened around the support and fixed to the rods of the
banner in such a way to fix the banner to the support.
[0006] The banner of the prior art and the fixing means that are currently used to fix the
banner to a support are impaired by some drawbacks.
[0007] A first drawback consists in the fact that, when similar banners are exposed to a
very strong wind, they tend to act as a "sail" and discharge the wind force on the
support, making the support fall, in the worst cases, with the risk of causing personal
injuries or damage to properties situated under the banner.
[0008] In fact, when the banners are hit by the wind, they are susceptible to a force that
tends to deform them. However, being tensioned, the banners cannot deform and consequently
tend to discharge the force on the support, which may be inclined and fall.
[0009] The force applied to the banner because of the wind is in direct proportion to the
area of the banner exposed to the wind. In other words, the worst condition is when
the wind hits the front or the back side of the banner.
[0010] Moreover, the larger the area of the banner, the higher the impact of the wind on
the banner will be.
[0011] A second drawback consists in the fact that the brackets used to fix the banner to
the support are made of a non-deformable material and, therefore, they are not suitable
for fixing the banner to all kinds of support. In fact, such brackets can be exclusively
attached to suitable supports.
[0012] Moreover, such brackets must be mounted and dismounted every time the banner needs
to be replaced, i.e. an operator needs to be lifted to reach the brackets in order
to remove them, then the banner has to be replaced and fixed again to the support
by means of the brackets.
[0013] It must be noted that such banners are usually mounted in a very high position with
respect to the ground, and consequently lifting baskets must be used in order for
the operator to reach the brackets. Otherwise said, the replacement of the banner
is a time-consuming, complicated, expensive and risky operations for the operator.
[0014] US2005/184206 A1 discloses a banner fixed to a supporting member. Such banner comprises a body having
flexible rods disposed into slots obtained in upper and lower position in the body.
Such rods are made in one piece and only permit a slight deformation of the banner
body when the banner is hit by the wind. In view of the above, in spite of the bending
of the rods, the impact surface of the banner with the wind is large, reducing the
resistance and the stability of the banner.
[0015] The purpose of the present invention is to overcome the drawbacks of the prior art
by providing a folding banner support assembly that is capable of withstanding the
impact of the wind and guarantees the stability of the supporting member, thus preventing
any harmful stress for the supporting member.
[0016] Another purpose is to disclose a folding banner support assembly that can be used
with supporting members of any shape and allows for fixing or replacing a banner on
the supporting member rapidly and easily.
[0017] The folding banner support assembly according to the invention comprises a banner,
comprising a flexible body with a slot, and a flexible and/or folding rod disposed
inside said slot.
[0018] The folding banner support assembly comprises fixing means that are fixed to the
banner in order to fix the banner to a supporting member.
[0019] The peculiarity of the folding banner support assembly according to the invention
consists in the fact that the rod is made of multiple mobile parts. The rod comprises:
- a fixed portion with a longitudinal axis;
- at least one mobile portion movably fixed to the fixed portion; and
- hinging means that hinge the mobile portion to the fixed portion, in such a way to
let the mobile portion rotate with respect to the fixed portion around a hinging axis
that is orthogonal to said longitudinal axis of the fixed portion.
[0020] The advantages of the folding banner support assembly according to the present invention
are evident: because of the provision of the folding and/or flexible rod that is made
of multiple mobile parts, the impact surface of the banner with the wind can be reduced
when the banner is exposed to the strength of the wind. In this way, the banner does
not cause the fall of the supporting member.

[0022] With reference to Figs. 1, 2 and 3, a folding banner support assembly according to
the invention is disclosed, which is generally indicated with reference numeral 100.
[0023] The folding banner support assembly (100) is intended to be mounted on a vertical
supporting member (P), such as for example a pole.
[0024] With reference to Figs. 1, 2, 3, 14 and 15, the folding banner support assembly (100)
comprises a banner (1) comprising a flexible body (10) obtained with a rectangular
sheet.
[0025] The body (10) comprises an upper edge (10a), a lower edge (10b) and two side edges
(10c). Moreover, the body (10) comprises a first side (10d), intended to face the
vertical support (P) and a second side (10e) opposite to the first side (10d). Advantageously,
one or more sides (10d 10e) of the body (10) of the banner (1) has an advertising
message.
[0026] The body (10) comprises a first slot (11) obtained on the upper edge (10a) of the
body (10) and a second slot (12) obtained on the lower bottom (10b) of the body (10).
[0027] The body (10) comprises a first transverse hole (13) obtained in the proximity of
the upper edge (10a) of the body (10) in communication with the first slot (11) and
a second transverse hole (14) obtained in the proximity of the lower edge (10b) of
the body (10) in communication with the second slot (12). The transverse holes (13,
14) are equidistant from the side edges (10c) of the body (10). Advantageously, the
transverse holes (13, 14) are obtained on the back side (10d) of the body (10).
[0028] With reference to Fig. 15, the banner (1) comprises two rods (8), each of them being
disposed inside one of the slots (11, 12) of the body (10) and having a substantially
horizontal direction.
[0029] With reference to Figs. 16 and 17, the rods (8) are flexible and/or folding rods.
In particular, each rod (8) comprises a fixed portion (80) and one or more mobile
portions (81) removably fixed to the fixed portion (80). The fixed portion (80) has
a longitudinal axis (X). The fixed portion (80) is disposed in correspondence of the
transverse hole (13, 14) of the body (10), and one or more mobile portions (81) is
fixed to the fixed portion (80).
[0030] Each rod (8) comprises two rows of mobile portions (81); the mobile portions (81)
of each row are mutually connected. Each row of mobile portions (81) comprises a first
ending section that is laterally fixed to the fixed portion (80), in such a way that
the fixed portion (80) is situated in central position with respect to the two rows
of mobile portions (81), and a second ending section connected to an ending portion
(82) of the rod (8).
[0031] With reference to Figs. 16 and 17, hinging means (9) connect the mobile portions
(81) together, and the mobile portions (81) to the fixed portion (80). In view of
the above, the mobile portions (81) can rotate with respect to the fixed portion (80)
and with respect to the adjacent mobile portions (81) around a hinging axis that is
orthogonal to said longitudinal axis (X) of the fixed portion.
[0032] As shown in Figs. 18 and 19, the hinging means (9) comprise:
- two shelves (80a) protruding from one side of the fixed portion,
- two shelves (81 b) protruding from one side of the mobile portion, and
- a pin (90) inserted in holes obtained in the shelves (80a) of the fixed portion and
in the shelves (81 b) of the mobile portion.
[0033] The axis of the pin (90) corresponds to the axis of the hinge that is orthogonal
to the longitudinal axis (X) of the fixed portion.
[0034] Although the figure shows this specific example of the hinging means (9), the hinging
means (9) can be made in any way that is known to an expert of the field, as long
as the hinge axis of the hinging means is vertical and orthogonal to the longitudinal
axis (X) of the fixed portion. Obviously, the hinging means can provide for only one
shelf with a pin joined to the mobile portion (81) or to the fixed portion (80) and
only one shelf with hole joined to the mobile portion (81) or to the fixed portion
(80), or they may provide for pin-sleeve rotation systems or bearings rotation systems.
[0035] With reference to Fig. 19, for each side, each mobile portion (81) comprises two
shelves (81 a, 81 b) that protrude from the mobile portion (81).
[0036] In particular, the shelves (81 a) that protrude from a first side of the mobile portion
(81) are identical to the shelves (80a) of the fixed portion (80).
[0037] The shelves (81 b) that protrude from a second side of the mobile portion (81) are
spaced by a distance that is lower than the distance between the shelves (81 a) that
protrude from the first side of the mobile portion (81). In this way, the shelves
(81 b) that protrude from a second side of the mobile portion (81) can be inserted
between the shelves (80a) of the fixed portion (80) or between the shelves (81 a)
of the first side of the mobile portion (81). Each shelf (81 b) of the second side
of the mobile portion (81) has an internal side (81 c) directed towards the internal
side (81 c) of the other shelf (81 b) of the second side of the mobile portion (81).
[0038] With reference to Fig. 20, the hinging means (9) also hinge the mobile portions (81)
to the ending portions (82) of the rod, in such a way that the mobile portions (81)
can rotate both with respect to the fixed portion (80) and to the ending sections
(82) of the rod.
[0039] In particular, the hinging means (9) also comprise shelves (82a) that protrude only
from one side of each ending section (82) of the rod and revolvingly connected to
the second ending section of the two rows of mobile portions (81) by means of the
pins (90). More precisely, the pins (90) are inserted in holes obtained on the shelves
(82a) of the ending portions (82) and on the shelves (81 a) of the first side of the
mobile portions (81) at the ends of the rod, in such a way to revolvingly connect
the mobile ending portions (81) to the ending portions (82) of the rod. Said shelves
(82a) of the ending portions (82) are identical to the shelves (81 b) of the second
side of the mobile portion (81), in such manner to be inserted between the shelves
(81 a) of the first side of the mobile ending portion (81). Each shelf (82a) of the
ending portion (82) has an internal side (82c) directed towards the internal side
(82c) of the other shelf (82a) of the ending portion (82).
[0040] With reference to Fig. 17, the axes of rotation of the pins (90) of the hinging means
are parallel and orthogonal to the longitudinal axis (X) of the fixed portion of the
rod. The pins (90) are disposed in holes obtained in the shelves (80a, 81 a, 81 b,
82a) of the portions (80, 81, 82) of the rod (8), in such a way to revolvingly connect
the portions (80, 81, 82) of the rod (8). It must be noted that the pins (90) are
prevented from coming out of the holes of the shelves (80a, 81 a, 81 b, 82a) of the
portions (80, 81, 82) of the rod (8) by caps (92) inserted in the holes of the shelves
(80a, 81 a, 81 b, 82a), and by screws (91) screwed in the pins (90).
[0041] Advantageously, the pins (90) let the portions (80, 81, 82) rotate by approximately
90°.
[0042] As shown in Figs. 16, 17, 19, 20, 21, 22 and 23, each rod (8) comprises retention
means (R), each of them being disposed between adjacent portions and comprising a
retention member (R1), such as for example a spring, and a pair of cam devices (R2)
disposed at the ends of the retention means (R1). The pin (90) is disposed inside
the retention member (R1) and inside holes of the cam devices (R2).
[0043] The cam devices (R2) are inserted between the shelves (81 b) of the second side of
the mobile portion (81) and between the shelves (82a) of the ending portion (82) of
the rod (8) and comprise a fork that protrudes laterally and is provided with an inlet
that houses a section of the fixed portion (80) or of the adjacent mobile portion
(81).
[0044] The cam devices (R2) are free to slide along a direction parallel to the axis of
rotation of the pin (90), but cannot rotate together with the pin (90) because the
fork prevents the rotation of the cam device (R2).
[0045] An external side (R2a) of each cam device (R2) is interfaced with the internal side
(81 c, 82c) of one of the shelves (81 b, 82a) of the second side of the mobile portion
(81) or of the ending portion (82). In particular, the external side (R2a) of each
cam device (R2) is provided with inlets and/or projections and the internal side (82c,
81 c) of the shelves (82a, 81 b) of the ending portion (82) and of the second side
of the mobile portion (81) is provided with projections and/or inlets, which cooperate
with the inlets and/or projections of the external side (R2a) of the cam device (R2),
in such a way to move the cam devices (R2) closer when the mobile portion (81) or
the ending portion (82) rotate. The movement of the cam devices (R2) loads the retention
member (R1).
[0046] The external side (R2a) of each cam device (R2) and the internal side (82c, 81 c)
of the shelves (82a, 81 b) of the ending portion (82) and of the second side of the
mobile portion (81) are complementary and coupled together.
[0047] In particular, when the portions (80, 81, 82) are aligned, the retention member (R1)
is preloaded. The initial preloading of the retention member (R1) permits to keep
the portions (80, 81, 82) of the rod (8) of the banner (1) in aligned position, until
they are susceptible to such a force that they can overcome the initial preloading
of the retention member (R1) and can rotate mutually. This avoids the deformation
of the banner (1) also in case of a very weak wind. The retention member (R1) is loaded
further when the mobile portions (81) or the ending portions (82) rotate. In fact,
during the rotation of the mobile portion (81) or of the ending portion (82), the
cam devices (R2) cannot rotate because they are blocked by the fork. Simultaneously,
during the rotation, the internal side (82c, 81 c) of the shelves (82a, 81 b) cooperates
with the external side (R2a) of the cam device (R2). The inlets and/or projections
provided on the external side (R2a) of the cam device (R2) and on the internal side
(82c, 81 c) of the shelves (82a, 81 b) of the ending portion (82) and of the second
side of the mobile portion (81) will move the two cam devices (R2) closer. Such a
movement causes a compression of the retention member (R1). Otherwise said, a rotatory
movement of a mobile portion (81) or of an ending portion (82) is converted into a
sliding movement of the cam device (R2) along an axis parallel to the axis of rotation
of the pin (90), which causes the compression of the retention member (R1).
[0048] It must be noted that the shelves (80a) of the fixed portion (80) and the shelves
(81 a) of the first side of the mobile portion (81) have a planar internal side.
[0049] When the banner (1) is susceptible to an external force, such as for example the
wind that hits the body (10), the mobile portions (81) and the ending portions (82)
of the rod (8) rotate around the pins (90) with respect to the fixed portion (80),
thus reducing the impact surface of the banner with the wind, as shown in Figs. 27
to 32 and Figs. 34 to 40, and preventing the support (P) from falling.
[0050] When a mobile portion (81) or an ending portion (82) rotates, the cam devices (R2)
are moved closer and load the retention member (R1). When the force of the wind is
stopped or reduced, the spring is unloaded, moving the cam devices (R2) away and aligning
the mobile portion (81) and the ending portion (82) to the fixed portion (80).
[0051] Therefore, because of the special configuration of the rods (8) made of mobile portions
(81) that are mutually hinged, when the banner (1) is hit by the wind, the banner
(1) can be in a configuration in which the impact surface with the wind is very small.
[0052] With reference to Figs. 1 to 7, the banner support assembly (100) comprises fixing
means (2) intended to be fixed to a support (P), and supporting means (B), shown in
Figs. 8, 9 and 10, fixed to the fixing means (2) and to the banner (1) to attach the
banner (1) to the fixing means (2).
[0053] The fixing means (2) comprise at least one fixing belt (20) intended to be disposed
around the support (P). As shown in Fig. 3, the fixing means (2) comprise two identical
belts fixed to the support (P).
[0054] The fixing means (2) also comprise an adjustment pawl (23) fixed to each fixing belt
(20) in order to tighten or enlarge the fixing belt (20) with respect to the support
(P). Advantageously, the adjustment pawl (23) is embedded in the fixing belt (20).
[0055] The fixing means (2) comprise two fixing devices (21), each of them being fixed to
a fixing belt (20). In particular, each fixing device (21) comprises first lock pins
(24), disposed in lateral position on the fixing device (21) in order to fix the fixing
belt (20) to the fixing device (21).
[0056] As shown in Figs. 5 and 7, optionally, the fixing device (21) has a rubber side (21
c) intended to be disposed in contact with the support (P). Such a rubber side (21
c) prevents the fixing device (21) from sliding on the support (P). The rubber side
(21 c) is fixed to the fixing device (21) by means of screws (21 d), as shown in Figs.
5 and 7. Optionally, the rubber side (21 c) is adhered to the fixing device (21) or
made in one piece with the fixing device (21).
[0057] With reference to Figs. 8, 9 and 10, the supporting means (B) comprise a bar (6)
attached to the fixing devices (21) in such a way that the bar (6) is parallel to
the support (P). In particular, as shown in Figs. 5, 6 and 7, each fixing device (21)
comprises a housing (21 a) that houses one end of a hook (65), disposed in correspondence
of a first upper ending section (63) and of a second lower ending section (64) of
the bar (6).
[0058] Moreover, as shown in Figs. 4, 5, 6, 7 and 24, the fixing device (21) comprises a
through hole (21 b) in communication with the housing (21 a) of the fixing device
(21). As shown in Fig. 9, the hooks (65) of the supporting means (B) comprise a hole
(66) aligned with the through hole (21 b) of the fixing device (21), when the hooks
(65) of the supporting means (B) are inserted in the housing (21 a) of the fixing
device (21).
[0059] As shown in Fig. 24, the fixing means (2) comprise a second lock pin (25) intended
to be inserted in the hole (66) of the hooks (65) and in the through hole (21 b) of
the fixing device (21) in order to fix the bar (6) to the fixing device (21).
[0060] As shown in Figs. 8 to 10, the bar (6) advantageously has a quadrangular section
and comprises a perimeter wall (60), a longitudinal cavity (61) defined by the perimeter
wall (60), and a longitudinal notch (62) providing access to the longitudinal cavity
(61), which is obtained on one side of the perimeter wall (60) of the bar (6).
[0061] The supporting means (B) comprise a cover (67) that closes the top of the longitudinal
cavity (61) of the bar (6). The cover (67) is fixed to the bar with screws (67c),
as shown in Fig. 10.
[0062] With reference to Figs. 8, 9 and 11, the banner support assembly (100) comprises
moving means (3) fixed to the banner (1) and to the supporting means (B) in order
to move the banner (1) with respect to the supporting means (B).
[0063] The moving means (3) comprise a mobile hook (30) fixed to said banner (1) in order
to support said banner (1);
[0064] In particular, the mobile hook (30) is slidingly disposed inside the longitudinal
notch (62) of the bar (6), in such manner to protrude externally from the bar (6).
[0065] One end of the mobile hook (30) is inserted in the first transverse hole (13) of
the banner (1), which is obtained in correspondence of the upper edge (10a) of the
body (10) of the banner (1). The fixed portion (80) of the rod (8) of the banner (1),
which is disposed in the first slot (11), is fixed to the mobile hook (30).
[0066] The moving means (3) comprise a moving device (4) fixed to the mobile hook (30) and
to the bar (6) in order to move the mobile hook (30) with respect to the supporting
means (B).
[0067] In particular, the moving device (4) is inserted in the longitudinal cavity (61)
of the bar (6) and is fixed to the second ending section (64) of the bar (6), in such
a way to close the bottom of the longitudinal cavity (61) of the bar (6).
[0068] As shown in Fig. 12, the moving device (4) comprises a body (40) that is fixed to
the supporting means (B), and a pulling pulley (41) that is fixed to the body (40)
by means of a pin (41 b) with axis of rotation perpendicular to the longitudinal axis
of the bar (6).
[0069] The pulling pulley (41) is inserted in the longitudinal cavity (61) of the bar (6)
and comprises a plurality of through holes (41 a), shown in Fig. 9, with axes parallel
to the axis of rotation of the pulling pulley (41). The through holes (41 a) are disposed
near the perimeter edge of the pulling pulley (41). As shown in Fig. 25, the moving
means (3) comprise a lock pin (34) intended to be exactly inserted into one of the
through holes (41 a) of the pulling pulley (41) in order to prevent the pulling pulley
from rotating (41).
[0070] The moving device (4) comprises moving means (42) fixed to the drive pulley (41)
in order to actuate the drive pulley (41) with respect to the body (40) of the moving
device (4). In particular, as shown in Fig. 24, the moving means (42) comprise a crank
(42a) intended to pass through an opening (68) that provides access to the pulling
pulley (41), obtained on the perimeter wall (60) of the bar (6) to cooperate with
the pin (41 b) of the pulling pulley (41) and rotate the pulling pulley (41).
[0071] Alternately, the moving means (42) can comprise an electrical actuator, intended
to move the pulling pulley (41) automatically.
[0072] As shown in Fig. 12, the moving device (4) comprises a fixed hook (43) that protrudes
from the body (40) of the moving device (4) and is fixed to the banner (1) in order
to support the banner (1). The fixed hook (43) protrudes from the longitudinal notch
(62) of the bar (6) and is inserted in the second transverse hole (14) of the body
(10) of the banner (1). The fixed hook (43) is fixed to the fixed portion (80) of
the rod (8) that is disposed in the second slot (12) of the banner (1).
[0073] The moving means (3) comprise a transmission member (33), shown in Fig. 11, revolvingly
connected to the drive pulley (41) of the moving device (4) and to the mobile hook
(30) in order to transmit the motion from the moving device (4) to the mobile hook
(30).
[0074] The transmission member (33) is an annular cable disposed in the longitudinal cavity
(61) of the bar (6). The transmission member (33) is disposed in contact with the
pulling pulley (41) of the moving device (4), in such manner that the pulling pulley
(41) rotates the transmission member (33). The transmission member (33) is fixed to
the mobile hook (30), in such manner to permit the ascending and descending travels
of the mobile hook (30), with respect to the bar (6).
[0075] As shown in Figs. 11 and 13, the moving means (3) comprise a supporting device (5)
that is fixed to the transmission member (33) and to the supporting means (B) in order
to support and tension said transmission member (33).
[0076] In particular, the supporting device (5) is disposed in correspondence of the first
ending section (63) of the bar (6). The supporting device (5) comprises a body (50)
that is fixed to the cover (67) of the supporting means (B), and a pulling pulley
(51) that is fixed to the body (50) by means of a pin (51 b) with axis of rotation
perpendicular to the longitudinal axis of the bar (6).
[0077] The idle pulley (51) is disposed in contact with the transmission member (33), in
such manner to support and tension the transmission member (33). By rotating, the
transmission member (33) moves the idle pulley (51).
[0078] As shown in Figs. 8 and 9, the banner support assembly (100) comprises an adjustment
screw (7) in order to fix the supporting device (5) to the first ending section (63)
of the bar (6) in such manner that, by screwing the adjustment screw (7), the supporting
device (5) is moved away from the moving device (4) and is moved closer to the cover
(67) of the supporting means (B), thus tensioning the transmission member (33).
[0079] In particular, the cover (67) of the supporting means (B) comprises a hole (67a)
and the body (50) of the supporting device (5) comprises a threaded hole (52) aligned
with the hole (67a) of the cover (67). The adjustment screw (7) is inserted in the
hole (67a) of the cover (67) and is screwed in the threaded hole (52) of the body
(50) of the supporting device (5), in such manner that by screwing the adjustment
screw (7) in the threaded hole (52) of the body (50) of the supporting device (5),
the supporting device (5) is moved closer to the cover (67), tensioning the transmission
member (33). By unscrewing the adjustment screw (7), the supporting device (7) is
moved away from the cover (67), loosening the transmission member (33).
[0080] Advantageously, the moving means (3) comprise a spring (35), s shown in Figs. 9 and
11, disposed on the transmission member (33) in order to tension the body (10) of
the banner (1) further. In fact, when the banner (1) is extended and attached to the
mobile hook (30) and to the fixed hook (43), a rotation of the moving means (42) determines
a compression of the spring (35), consequently tensioning the body (10) of the banner
(1).
[0081] Advantageously, the moving means (3) comprise a locking bracket (36) fixed to the
transmission member (33) to lock the rotation of the transmission member (33).
[0082] As shown in Fig. 25, the banner support assembly (100) comprises a safety device
(S) that is fixed to the rods (8) in order to prevent the rods (8) from being released
accidentally.
[0083] In order to install the banner support assembly (100) to a support (P), it is necessary
to fix the fixing belts (20) of the fixing means (2) to the support (P) and tighten
the fixing belts (20) to the support (P) by means of the adjustment pawl (23).
[0084] The transmission member (33) is disposed in contact with the pulleys (41, 51) of
the moving device (4) and of the supporting device (5).
[0085] The moving means (3) are fixed to the supporting means (B). In particular, the moving
device (4) is fixed to the bar (6) in lower position and the supporting device (5)
is fixed to the bar (6) in upper position. The transmission member (33) is inserted
in the longitudinal cavity (61) of the bar (6), in such manner that the mobile hook
(30) protrudes from the longitudinal notch (62) of the bar (6).
[0086] The adjustment screw (7) is inserted in the hole (67a) of the cover (67) and is screwed
in the threaded hole (52) of the supporting device (5), in such manner to tension
the transmission member (33).
[0087] The supporting means (B) are attached to the fixing devices (21) of the fixing means
(2).
[0088] The banner (1) is fixed to the moving means (3). In particular, the mobile hook (30)
is fixed to the fixed portion (80) of the rod (8) inserted in the first slot (11)
of the banner (1).
[0089] The pulling pulley (41) is actuated by means of the moving means (42) in such manner
to rotate the transmission member (33). Consequently, the mobile hook (30) slides
upwards, pulling the banner (1) along, as shown in Fig. 26.
[0090] The rotation of the pulling pulley (41) ends when the rod (8) disposed in the second
slot (12) of the banner (1) is situated in correspondence of the fixed hook (43) of
the moving device (4).
[0091] The fixed hook (43) is fixed to the fixed portion (80) of the rod (8) that is disposed
in the second slot (12) of the banner (1).
[0092] By rotating the moving means (42) further, the spring (35) of the moving means (3)
is loaded and the banner (1) is tensioned.
[0093] The rotation of the pulling pulley (41) is locked by inserting the lock pin (34)
in the through holes (41 a) of the pulling pulley (41).
[0094] Therefore, because of the provision of the moving means (3) of the banner support
assembly (100), the banner (1) can be replaced easily and rapidly, without having
to dismount the supporting means (B) and without requiring the operator to reach the
fixing means (2).
[0095] Moreover, said fixing means (2) can be attached to supports (P) with any sectional
shape.
[0096] Although reference is made to a banner support assembly comprising a banner attached
to the moving means in a central position of the rods, the rods may be projection
rods. Moreover, only one rod may be provided.
