Technical field
[0001] The present invention relates to a motorized control system for controlling the movement
of at least one leaf intended for opening or closing, at least partially, an opening,
such as a window, in a wall.
[0002] Such systems are generally much appreciated, particularly when applied to windows,
in that they allow a user to automatically open or close the shutters without having
to manually push said shutters or lean out of the window.
Background art
[0003] More specifically, the present invention relates to a system according to the preamble
of the appended claim 1, i.e. a system of the above-mentioned type comprising:
- an actuator or motor device adapted to be secured to said wall; and
- a rotatable element adapted to be constrained to said leaf and to be rotated about
an actuation axis by means of said actuator or motor device, in such a way as to move
said leaf in order to open and/or close said opening.
[0004] However, systems of this type suffer from a few drawbacks.
[0005] One drawback is that the actuator or motor device and the rotatable element are rigidly
connected and constrained to each other in rotation to allow the exertion of an appropriate
thrust or pull on the leaf in order to cause it to open or close, and they cannot
be decoupled for manually moving the leaf.
[0006] This situation proves to be uncomfortable especially in the event of a malfunction
of the actuator device or an interruption of the power supply to the system. In both
of these cases, the leaf will stay locked in the position it was in prior to the malfunction
or the power blackout, and it cannot be brought manually into the desired position
until the actuator device is repaired or power is restored.
[0007] This operation becomes even more complex when the actuator or motor device is protected
by enclosures, implying the necessity of disassembling the rotatable element from
the output shaft of the actuator or motor device and then removing enclosure components
to be able to properly work on the system.

[0013] It is one object of the present invention to provide a system which can overcome
this and other drawbacks of the prior art, while at the same time being simple and
economical to manufacture.
[0014] According to the present invention, this and other objects are achieved through a
system made in accordance with the appended claim 1.
[0015] It is understood that the appended claims are an integral part of the technical teachings
provided in the following detailed description of the invention.

Detailed description of the invention
[0017] With reference to Figure 1, numeral 10 designates as a whole an exemplificative embodiment
of a system according to the present invention.
[0018] System 10 is designed for motorized control of the movement of at least one leaf
A adapted for opening or closing, at least partially, an opening F in a wall P.
[0019] In the embodiment shown in Figure 1, the above-mentioned opening is a window F that
can be closed or opened by a pair of leaves A which are movably mounted to wall P
in the vicinity of opposite sides of window F. However, as will become apparent to
a man skilled in the art from the following description, the system of the present
invention is also applicable to different configurations; for example, it may control
the movement of a single leaf adapted to close the entire opening defined through
the wall. Furthermore, the system of the invention is not only applicable for opening
or closing leaves of windows, since it can also be used for opening or closing leaves
associated with doors or other openings in a generic wall.
[0020] In addition, in the illustrated embodiment each leaf A is mounted to wall P in such
a manner that it can swivel. Preferably, the structure of leaf A mounted to wall P
is of the one-piece type; however, the system of the present invention is also suitable
for use on leaves of a different type, e.g. of the so-called "Paduan" type (where
leaf portions can be folded outwards from opening F). By using a suitable transmission
mechanism, it is also conceivable to use the system in combination with sliding leaves,
e.g. of the type "hiding" into wall P).
[0021] Furthermore, in the illustrated embodiments leaves A are shutters, i.e. they are
"solid", their wall having no apertures or interruptions; as an alternative, the leaves
may also be in the form of louvers, i.e. with apertures or interruptions through which
light from the outside can enter the room. As is known in the industry, the apertures
or interruptions in such louver-type leaves can be obtained through a plurality of
transverse boards stacked parallel to one another, slightly inclined relative to the
plane defined by the leaf itself.
[0022] In Figure 1, leaves A adapted to close window F are shown in the wide open position.
[0023] With particular reference to Figures 2 and 3, system 10 comprises:
- an actuator o motor device 14 adapted to be mounted to wall P in the proximity of
opening F, preferably by means of a support structure 12 whereon it is prearranged
for being supported or hung; and
- a rotatable element 16, e.g. an arm, adapted to be constrained to leaf A and to be
rotated about an actuation axis X-X by means of actuator or motor device 14, in such
a way as to move leaf A in order to open and/or close opening F.
[0024] As already described, in the illustrated embodiment leaf A can swivel because it
is hingedly mounted to wall P.
[0025] System 10 further comprises disengageable transmission means, designated as a whole
18, which comprise a drive portion 20 and a driven portion 22 rotatably cooperating
with actuator or motor device 14 and with rotatable element 16, respectively. Drive
portion 20 and driven portion 22 can be placed in:
- a disengaged condition (Figures 6 and 8), wherein they are rotatably independent of
each other and movable relative to each other among a plurality of predetermined mutual
arrangements, each one of said mutual arrangements corresponding to an associated
angular position that can be taken by leaf A; and
- an engaged condition (Figures 5 and 7), wherein they rotatably cooperate together
in a mutual arrangement which can be selected among said plurality of predetermined
mutual arrangements and which corresponds to a desired angular position of leaf A.
[0026] Thanks to the presence of transmission means 18, even an unskilled user can make
a manual adjustment of the angular position of leaves A in the event of a malfunction
of motor device 14 or an interruption of the power supply to said motor 14. In fact,
the user can switch drive portion 20 and driven portion 22 from the engaged condition
(of normal use) to the disengaged condition (of adjustment) and move them in such
a way as to cause them to take the mutual arrangement corresponding to the desired
angular position of leaf A. Then the user can bring drive portion 20 and driven portion
22 again into the engaged condition, wherein they rotatably cooperate together and
are locked into the selected mutual arrangement.
[0027] The illustrated embodiment shows a merely exemplificative way of mounting support
structure 12 and actuator or motor device 14 to wall P. In this embodiment, the actuator
or motor device 14 is mounted to the top edge or "lintel" of opening F. For example,
said actuator or motor device 14 is secured to wall P through a support structure
12 made out of a metal section preferably comprising mounting holes (not numbered)
that allow it to be fastened to wall P by means of screws; in particular, when mounting
support structure 12 to wall P it is possible to use a jig M with guide holes (not
numbered) located in positions corresponding to said mounting holes. This makes it
possible to drill beforehand a plurality of holes into wall P (e.g. at the top edge
of opening A) exactly where indicated by the guide holes in jig M, which is useful
to ensure better precision when mounting support structure 12 to wall P.
[0028] In the illustrated embodiment, actuator or motor device 14 is substantially hung
on support structure 12, e.g. mounted thereto by means of screws. Preferably, device
14 is a continuously operating motor, but in less preferred variants it may be an
actuator operating in a discontinuous or discrete mode. In particular, device 14 is
an electric motor, e.g. a motoreducer, fitted with an output shaft 15 adapted to transfer
to rotatable element 16 a rotary motion about actuation axis X-X via transmission
means 18. In a
per se known manner, actuator or motor device 14 is adapted to be controllably operated
by a control unit adapted to be governed by the user through suitable control devices,
possibly remote ones, such as push-buttons, remote controls or domotic equipment.
[0029] In the illustrated embodiment, rotatable element 16 is an arm rotatable about actuation
axis X-X and connected on one side to actuator or motor device 14, in particular to
output shaft 15, via the transmission means, and on the other side to associated leaf
A via a suitable guide mechanism. Preferably, said guide mechanism comprises, in a
way
per se known in the industry, a slider 17 rotatably pivoted to the end of arm 16, and a
guide or rail G mounted to leaf A, to which rail slider 17 is slidably coupled, in
particular in straight motion.
[0030] Preferably, system 10 includes a protective enclosure made out of one or more boxed
elements or cases 19 adapted to protect actuator or motor device 14 and possibly also
said control unit. In the illustrated example, protective enclosure 19 can be at least
partly secured to support structure 12, so as to be at least partly superimposed on
actuator or motor device 14. Boxed elements 19 may be arranged side by side and include
intermediate sections, e.g. "C" sections, so as to enclose actuator or motor device
14 and protect it like a "shell" against the action of external agents, such as dust,
moisture, heat, etc. In such a case, a hole 19a may be present to allow the or motor
device 14 to protrude from enclosure 19, e.g. with its output shaft 15 only.
[0031] The drive portion 20 and driven portion 22 are rotatable about the same rotation
axis X-X. In the illustrated embodiment, rotation axis X-X and actuation axis X-X
coincide. As will be appreciated by a man skilled in the art, in further variant embodiments
the rotation axes of the drive portion and of the driven portion may not coincide
with each other or with the actuation axis of the rotatable element; for example,
such axes may be parallel to one another, or possibly oriented perpendicularly to
the actuation axis, through the interposition of more or less complex kinematic mechanisms
(e.g. bevel gears or the like).
[0032] In the illustrated embodiment, drive portion 20 and driven portion 22 are elements
which are distinct from associated actuator or motor device 14 and from associated
rotatable element 16. In further variant embodiments, instead, the drive portion and
the driven portion can be manufactured as one piece with the output shaft of the actuator
or motor device and with the rotatable element, respectively. Such a design is however
less preferred for maintenance reasons, since the entire output shaft or the entire
rotatable element will have to be replaced should the drive portion or the driven
portion break or malfunction.
[0033] Preferably, drive portion 20 and driven portion 22 are mutually movable in a guided
manner parallel to rotation axis X-X between the engaged condition, wherein they are
abutted and rotatably cooperating, and the disengaged condition, wherein they are
set apart and rotatably independent.
[0034] In the embodiment shown by way of example in Figures 2 and 3, when drive portion
20 and driven portion 22 are in the engaged condition or in the disengaged condition,
they are, respectively, in mutual contact, preferably in the direction of rotation
axis X-X, or detached from each other, preferably in the direction of rotation axis
X-X.
[0035] The drive portion 20 and driven portion 22 have an interface consisting of respective
contact surfaces 24 and 26 facing each other, e.g. axially, and having a substantially
matching shape, which are adapted to engage one into the other in a plurality of coupling
configurations corresponding to said mutual arrangements.
[0036] Each contact surface 24, 26 has a plurality of seats and/or protrusions arranged
peripherally with respect to rotation axis X-X and adapted to be coupled, in each
one of said mutual arrangements of drive portion 20 and driven portion 22, to respective
matching protrusions and/or seats on the other contact surface 26, 24.
[0037] In the illustrated embodiment, each contact surface 24, 26 has an alternated succession
of said seats and protrusions, which are adapted to be coupled, in each one of said
mutual arrangements, to matching protrusions and seats, respectively, on the other
contact surface 26, 24.
[0038] In the illustrated embodiment, the seats are radial grooves, whereas the protrusions
are radial reliefs. In particular, said grooves and reliefs are arranged in a sunburst
pattern on the respective drive portion 20 and/or on the respective driven portion
22.
[0039] Said alternated succession of grooves and reliefs is preferably obtainable, for example,
through a spline machining process carried out on axially opposed faces of drive portion
20 and of driven portion 22. Particularly but not necessarily, the grooves and reliefs
of transmission means 18 have a substantially triangular cross-section.
[0040] In the illustrated embodiment, contact surface 24 or 26 occupies a peripheral region
of associated drive portion 20 or of associated driven portion 22, in particular defining
an annular or circumferential area with said alternated succession of grooves and
reliefs. In this manner, said peripheral alternated succession defines a peripheral
profile substantially having a "saw-tooth" shape (also called "crown toothing").
[0041] In the illustrated embodiment, drive portion 20 and driven portion 22 have a disk-like
shape. In particular, such disks, preferably annular in shape, have a substantially
circular profile, with the same diameter for both portions 20, 22 of transmission
means 18. For example, contact surfaces 24 and 26 are circular crowns, slightly protruding
axially from the remaining parts of the disks defined the portions 20, 22.
[0042] Preferably, drive portion 20 and driven portion 22 are supported by output shaft
15 and relatively slidable thereon between the engaged condition and the disengaged
condition. In the illustrated embodiment, drive portion 20 is rotatably constrained
to output shaft 15, while driven portion 22 can be rotatably constrained to drive
portion 20 but is rotatably unconstrained from the motor shaft; drive portion 20 is
fixedly mounted on output shaft 15, while driven portion 22 is slidably mounted on
output shaft 15, parallel to rotation axis X-X.
[0043] In the illustrated embodiment, drive portion 20 has an axial through aperture 28
of polygonal shape, e.g. square, which is adapted to be coupled to a tapered intermediate
portion 30 of output shaft 15, having a polygonal shape matching axial aperture 28.
In particular, the peripheral crown defined by contact surface 24 extends around axial
aperture 28. This coupling contributes to firmly constraining together in rotation
output shaft 15 and drive portion 20.
[0044] In the illustrated embodiment, drive portion 20 has at least one pair of socket-head
screws or dowels 31 housed in corresponding transversal holes 32 angularly equidistant
from each other along the periphery of drive portion 20, e.g. in intermediate section
30. During assembly, socket-head screws 31 are tightened against the periphery of
output shaft 15, preferably into cavities (not numbered) transversally obtained therein.
This coupling contributes to preventing drive portion 20 from undesirably translating
relative to output shaft 15.
[0045] In the illustrated embodiment, driven portion 22 has an axial through aperture 36
crossed by output shaft 15, so as to allow relative rotation between driven portion
22 and output shaft 15; in other words, driven portion 22 and output shaft 15 are
rotoidally coupled via axial through aperture 36. This ensures a guided coupling between
driven portion 22 and output shaft 15, while at the same time allowing relative rotation
between them.
[0046] In particular, axial through aperture 36 may have a circular cross-section crossed
by a distal portion 38 of output shaft 15, which in turn has a cross-section which
is substantially complementary to that of axial through aperture 36. Preferably, the
transversal extension of distal portion 40 is shorter than that of intermediate portion
30.
[0047] In the illustrated embodiment, driven portion 22 is secured to rotatable element
or arm 16, particularly at one end 40 thereof. In particular, driven portion 22 has
a plurality of axial holes 42 located on the side axially opposite to contact surface
26. Preferably, the coupling between driven portion 22 and rotatable element 16 is
effected by means of screws mounted therethrough; in particular, said coupling is
effected by tightening the screws through axial holes 42 and orifices 44 present on
rotatable element 16, e.g. at end 40, in positions corresponding to those of axial
holes 42. In this example, axial holes 42 are angularly equidistant from rotation
axis X-X.
[0048] In the illustrated embodiment, rotatable element 16 has in its turn an axial through
aperture 46, e.g. having a circular cross-section, located in a position corresponding
to axial through aperture 36 of driven portion 22. The arrangement and alignment of
axial through apertures 36 and 46 is such as to allow output shaft 16 to pass through
them, while at the same time ensuring freedom of rotation of the assembly formed by
rotatable element 16 and driven portion 22 with respect to said output shaft 16.
[0049] In the illustrated embodiment, axial through aperture 46 of rotatable element 16
has a circular cross-section of substantially the same diameter as distal portion
38 of output shaft 15, thus allowing them to slide in a guided manner relative to
each other.
[0050] With particular reference to Figures 5 to 8, system 10 further comprises a control
member 48 which can be operated by a user and which is adapted to cause drive portion
20 and driven portion 22 to slide relative to each other between an engaged condition
(working position of control member 48) and the disengaged condition (disengaged position
of control member 48). In particular, control member 48 is adapted to cause driven
portion 22 to slide over motor shaft 15, away or towards drive portion 20.
[0051] Control member 48 is rotatably mounted to output shaft 15. In particular, control
member 48 is a lever rotatably mounted about an oscillation axis Y-Y in the proximity
of the free end of output shaft 15, particularly of distal portion 38 thereof. For
example, oscillation axis Y-Y is substantially perpendicular to rotation or actuation
axis X-X.
[0052] With particular reference to Figures 7 and 8, control member 48 has a cam profile
50 designed for moving, by pushing them, drive portion 20 and driven portion 22 relative
to each other between the engaged condition and the disengaged condition. Preferably,
cam profile 50 cooperates with driven portion 22; in particular, cam profile 50 has
a lobed portion (not numbered) eccentrically protruding relative to oscillation axis
Y-Y and cooperating with driven portion 22 to push it against drive portion 20 into
the engaged condition (working position, shown in Figures 5 and 7), and a non-lobed
portion (not numbered) capable of receiving, in abutment thereon, driven portion 22
to move it away from drive portion 20 into the disengaged condition (idle position,
shown in Figures 6 and 8).
[0053] In the illustrated embodiment, cam profile 50 has a substantially arched shape, with
the longest radius of curvature at the lobed portion and the shortest radius of curvature
at the non-lobed portion.
[0054] In the illustrated embodiment, control member 48 comprises a handle 52 adapted to
be gripped by a user wanting to rotate the control member between the working position
and the idle position, and a thrust portion 54, with cam profile 50, coupled to handle
52. Handle 52 and thrust portion 54 are shown as two distinct parts coupled together,
but these two elements may also be designed as one monolithic piece.
[0055] In the illustrated embodiment, the rotary connection between control member 48 and
output shaft 15 is effected via thrust portion 54, which preferably has a substantially
fork-like shape. In particular, thrust portion 54 has a central or base region 56
with which handle 52 is associated, and a pair of side branches 58 (one of which is
only visible in Figures 7 and 8) protruding on opposite sides of central or base region
56, both of which having cam profile 50. Advantageously, side branches 58 extend on
diametrically opposed sides of shaft 28, particularly at distal portion 38 thereof.
For example, the rotary coupling about oscillation axis Y-Y may be obtained by diametrically
inserting a transversal element 60 through shaft 15, advantageously through distal
portion 38 thereof. In particular, transversal element 60 is inserted with freedom
of rotation through shaft 15 and secured at its ends to at least one of side branches
58. More particularly, transversal element 60 is a screw inserted through a diametric
through hole 62 obtained through shaft 15, e.g. through distal portion 38, and screwed
to one of the two side branches 58. In this case, oscillation axis Y-Y will correspond
to the axis of transversal element 60.
[0056] With particular reference to Figures 5 and 7, when transmission means 18 are in the
engaged condition, control member 48 is in the working position. In the illustrated
embodiment, when control member 48 is in the working position, it is substantially
aligned with output shaft 15, i.e. its prevalent extension is substantially parallel
to the rotation or actuation axis X-X. In this manner, cam profile 50 will have its
lobed portion facing towards driven portion 2, thus subjecting it to an axial thrust
towards drive portion 20.
[0057] With reference to Figures 6 and 8, when on the contrary transmission means 18 are
in the disengaged condition, control member 48 is in the idle position. In the illustrated
embodiment, when control member 48 is in the idle position, it is substantially perpendicular
to output shaft 15, i.e. its prevalent extension is substantially transversal, preferably
orthogonal, to rotation axis X-X. In this manner, cam profile 50 will have its non-lobed
portion facing towards driven portion 2, thus allowing the latter to move away by
gravity from drive portion 20.
[0058] In the illustrated embodiment, system 10 further includes an elastic element 62 which
tends to retain control member 48 when the latter is in its working position (that
is, when transmission means 18 are in the engaged condition). This avoids that, while
moving leaf A under the action of motor 14, the cooperation between drive portion
20 and driven portion 22 might generate an axial thrust undesirably causing control
member 48 to rotate towards its idle position (Figures 6 and 8), thus getting into
the disengaged condition.
[0059] In the illustrated embodiment, elastic member 62 encircles output shaft 15 and is
mounted axially between cam profile 52 of control member 48 and driven portion 22
(in particular in abutment on rotatable element or arm 16). Particularly, elastic
element 62 is a Belleville washer, e.g. with a central aperture crossed with transverse
play by output shaft 15, in particular by distal portion 38 thereof.
[0060] In the illustrated embodiment, elastic element 62 is axially arranged between thrust
portion 54, e.g. at side branches 58, and driven portion 22, e.g. through the additional
interposition of rotatable element or arm 16 (particularly end 40 thereof).
[0061] When normally in use, system 10 has transmission means 18 in their engaged condition,
so that drive portion 20 and driven portion 22 can cooperate to transfer the rotary
motion from motor 14 to leaf A via rotatable element or arm 16 and respective guide
or slider G. More in detail, contact surfaces 24 and 26 are kept axially coupled together
through the effect of the thrust exerted by the lobed portion of cam profile 50 under
the action of control member 48. In the engaged condition, therefore, output shaft
15 is made rotatably integral with rotatable element or arm 16. Of course, depending
on the direction of rotation imparted by motor 14, leaves A will move towards a partially
or wide open condition (Figure 1) or towards a partially or fully closed condition
(not shown).
[0062] Let us now consider the case wherein a user wants to re-adjust the angular position
of leaf A by means of system 10 after the first installation. In this situation, the
user can operate control member or lever 48 by moving it from the working position,
shown in Figures 5 and 7, to the idle position, shown in Figures 6 and 8, against
the countering action exerted by elastic element 62. Thus, drive portion 20 and driven
portion 22 will no longer be kept with their respective contact surfaces 24 and 26
coupled together, since driven portion 22 will move away from drive portion 20, abutting
against the non-lobed portion of cam profile 50, with rotatable element or arm 16
in between. Therefore, rotatable element or arm 16 can be freely turned until leaf
A will get into the desired angular position.
[0063] Subsequently, in order to put system 10 in operation again it will only be necessary
to turn control member or lever 48 to the working position, thereby loading elastic
element 62, which will tend to prevent the control member from undesirably returning
into the idle position (particularly while electric motor 14 is operating). Then control
member 48 will again cause surfaces 24 and 26 of drive portion 20 and of driven portion
22 to abut against each other, thanks to the thrust exerted by the lobed portion of
the profile 52. Note that the alternated succession of transversal grooves and reliefs
arranged in a sunburst pattern on contact surfaces 24 and 26 is particularly advantageous,
in that it allows for fine angular adjustments of the mutual position of drive portion
20 and driven portion 22, thus allowing them to be accurately adjusted with minimal,
almost continuous, angular increments between successive mutual angular arrangements
of drive portion 20 and driven portion 22.
[0064] Of course, without prejudice to the principle of the invention, the forms of embodiment
and the implementation details may be extensively varied from those described and
illustrated herein by way of non-limiting example, without however departing from
the scope of the invention as set out in the appended claims.
