FIELD OF THE INVENTION
[0001] The invention relates to a support mechanism for a closure element of a ventilation
and locking system, in particular a ventilation and locking system for a tilting window
or the like, the support mechanism being suitable for being mounted on a pivoting
sash of a closure assembly in order to support the closure element and to allow a
displacement of the closure element from a locking closed position in which the closure
element shuts a ventilation passage of the closure assembly to at least one ventilation
position in which the closure element is inclined relative to its closed position
while keeping the ventilation and locking system locked, a first air passage communicating
with the ventilation passage being created in a said ventilation position by increasing
a distance between a first longitudinal edge of the closure element and a frame member
of the closure assembly.
DESCRIPTION OF THE PRIOR ART
[0002] Such type of support mechanism is found for example in
CN101158259A or in the ventilation and locking system of the published German patent application
DE1905074A1 which describes a closure assembly such as a tilting window with a locking mechanism
actuated by a closure element like a flap. The locking mechanism provides an intermediate
locked position allowing the closure element to set in a single ventilation position
without unlocking the locking mechanism. The first air passage created in the ventilation
position is between a top longitudinal edge of the closure element and a top frame
member This device advantageously allows to ventilate a room through the ventilation
passage of the window while keeping the window closed and locked.
[0003] However, the flap is hinged on the sash through hinge elements which allow it to
pivot about a stationary axis extending along its lower longitudinal edge, said lower
edge always remaining therefore very close to the sash in the ventilation position,
typically at a distance less than 2 or 3 mm. Since in the ventilation position the
inclination of the flap relative to the sash is typically about 30° or less, this
configuration restrains the air flow through the ventilation passage. Indeed, the
air passing through the interior opening of the ventilation passage towards the inside
or the outside of the room is deflected by the flap, and there is no significant air
passage between the lower edge of the flap and the sash, which therefore reduces the
air speed and flow. For these reasons, ventilating the room through the ventilation
passage, i.e. when the window is closed and locked, is not very efficient.
SUMMARY OF THE INVENTION
[0004] To mitigate those drawbacks, and in particular to increase the air flow capacity
through the ventilation passage, the Applicant has found desirable to conceive a support
mechanism for a closure element like a ventilation flap allowing a ventilation position
with significant air passages between the flap and frame members of the closure assembly
to which the flap is in sealing contact when closed. In particular, the invention
aims at increasing significantly the distance between a bottom longitudinal edge of
the flap and the sash in the ventilation position.
[0005] To this end, the invention provides a support mechanism of the kind in question,
according to claim 1 or claim 11. By means of these dispositions, two significant
air passages are provided in a ventilation position between two longitudinal edges
of the closure element and frame members of the closure assembly, contrary to the
prior art device of
DE1905074A1 for which a single significant air passage is obtained. Further, that the hinged
structure is adapted so that said displacement of the closure element to a ventilation
position results from a combination of a translatory motion and a rotary motion; allows
to obtain any desired distance between a first or a second longitudinal edge of the
closure element and a frame member of the closure assembly. Further, that the hinged
structure comprises at least two support arms hinged to the closure element and is
adapted so that two support arms move relatively to each other during the displacement
of the closure element to a ventilation position; allows to incline the closure element.
In embodiments of a support mechanism according to the invention, the support mechanism
comprises one or more of the following dispositions :
said translatory and rotary motions may be performed simultaneously ;
the support arms are hinged to a supporting plate to which the closure element is
hinged and able to be secured ; which allows to pivot the closure element relative
to the support mechanism in an unlocking direction which is different from the direction
of displacement of the closure element to a ventilation position ;
the support arms are hinged to the closure element through a supporting plate which
is permanently secured to the closure element ; which provides a simple structure
for a ventilation and locking system in which the unlocking direction is the same
as the direction of displacement of the closure element to a ventilation position.
the hinged structure is arranged along a plane which is perpendicular to a longitudinal
axis of the closure element; which provides a relatively narrow structure for the
support mechanism which does not jeopardize the air section of the ventilation passage
of the closure assembly ;
the hinged structure comprises :
a supporting casing suitable for being secured to the sash ;
a first and a second pivoting arms each pivotally mounted on the supporting casing,
which are arranged parallel to each other ;
a link arm arranged so as to form with the first and second pivoting arms a sensibly
parallelogrammatic hinge structure allowing the link arm to be displaced while remaining
sensibly parallel to a predetermined direction, the link arm comprising an extension
part which forms a first support arm hinged to the closure element ; which provides
a compact structure for the support mechanism while allowing a relatively large displacement
of the closure element;
the first pivoting arm comprises an extension part which is jointed to an inclination
arm which forms a second support arm hinged to the closure element;
the hinged structure comprises :
a hinge support providing a curved guide path, suitable for being secured to the pivoting
sash;
a hinge mobile part hinged to the hinge support, comprising a curved sliding part
adapted to slide along said curved guide path so that said hinge mobile part can rotate
about a hinge axis remote from said hinge support, and further comprising a support
part on which is mounted the closure element.
[0006] The invention also provides a ventilation and locking system according to claim 6.
In embodiments of a ventilation and locking system according to the invention, the
ventilation and locking system comprises one or more of the following dispositions
:
the linking mechanism provides a free travel adapted so that the locking mechanism
is not actuated upon a displacement of the closure element to a ventilation position
; which allows that when the first longitudinal edge of the closure element moves
away from a frame member of the closure assembly to create the first air passage communicating
with the ventilation passage, a lock fitting comprising the locking mechanism remains
locked so that the closure assembly is ventilated while staying closed and locked
;
the closure element is hinged to the support mechanism so as to be able to pivot relative
to the support mechanism in an unlocking direction in order to actuate and unlock
the locking mechanism, the ventilation and locking system further comprising a latching
mechanism adapted to latch the closure element to the support mechanism ; which impedes
the closure element to pivot accidentally relative to the support mechanism when displacing
the closure element to a ventilation position and therefore ensures that the locking
mechanism remains locked in said ventilation position of the closure element;
the locking mechanism comprises a slider actuated by the linking mechanism and at
least one locking pin connected to the slider through a lever mechanism, the lever
mechanism being adapted so that when the closure element is displaced from its locking
closed position to a ventilation position, a corresponding displacement of the slider
does not displace the locking pin ; which allows that although the linking mechanism
does not provide a free travel, a lock fitting comprising the locking mechanism remains
locked in the ventilation position of the closure element.
[0007] The invention also provides a closure assembly according to claim 9.

DETAILED DESCRIPTION OF THE INVENTION
[0009] As represented in FIGS. 1 and 2, a ventilation and locking system 2 comprising a
first embodiment of a support mechanism 3 according to the invention is mounted on
a pivoting sash 10 of a window assembly 1. The support mechanism 3 supports a closure
element 15 consisting in a ventilation flap and is adapted so that the flap can be
set in a locking closed position in which it shuts a ventilation passage 5 of the
window assembly 1. In FIG. 1, the flap is represented in a ventilation position, i.e.
a position in which the flap 15 is inclined while keeping locked the ventilation and
locking system. In this embodiment of the window assembly 1, when the window is closed,
the ventilation passage 5 is created by a space between a top frame member 11 of the
pivoting sash 10 and a top frame member 101 of a main frame of the window.
[0010] The ventilation position represented is the maximum ventilation position provided
by the support mechanism 3, i.e. the support mechanism does not allow the flap to
be further moved away from the ventilation passage 5, as explained hereafter in reference
to FIG. 4. The displacement of the flap 15 from its locking closed position to the
maximum ventilation position results from a combination of a translatory motion T1
and a rotary motion R1, due to a hinged structure 30 of the support mechanism 3. The
hinged structure 30 is adapted to displace the flap to the maximum ventilation position
so that both top and bottom longitudinal edges respectively 15T and 15B of the flap
move away from the ventilation passage 5 (FIG. 1). Between the locking closed position
and the maximum ventilation position represented, a continuity of intermediate ventilation
positions is provided for the flap 15. Alternatively, several discrete intermediate
ventilation positions could be provided.
[0011] As a first and top longitudinal edge 15T of the flap separates from the top frame
member 101 of the window with an increasing distance G1, a first air passage 7 communicating
with the ventilation passage 5 widens until the flap is brought to the maximum ventilation
position (FIGS. 1, 2 and 4). Similarly, as a second and bottom longitudinal edge 15B
of the flap separates from the bottom frame member 11 of the pivoting sash 10 with
an increasing distance G2, a second air passage 8 communicating with the ventilation
passage 5 widens. The hinged structure 30 is adapted to incline the flap 15 so that
the second air passage 8 widens more than the first air passage 7, i.e. the distance
G2 sets greater than the distance G1. This configuration is advantageous to keep the
ventilation and locking system locked, as explained hereafter.
[0012] The top and bottom longitudinal edges 15T and 15B of the closure element 15 are defined
in reference to their respective positions relative to the sash 10 on which the closure
element is mounted. The top edge is defined as the distal edge, whereas the bottom
edge is defined as the proximal edge. Therefore, depending on the position of the
ventilation passage in the closure assembly, the top edge of the flap is not necessarily
located higher than the bottom edge.
[0013] The ventilation and locking system comprises two locking mechanisms 210 able to be
simultaneously actuated by the flap 15. The actuation of a locking mechanism 210 by
the flap 15 is performed through a linking mechanism 211 which is at one end hinged
to the locking mechanism and is at one other end hinged to the flap at the top longitudinal
edge 15T of the flap. The linking mechanism 211 comprises two rods hinged to each
other so that they provide a free travel when spreading until they set in alignment.
The free travel is adapted so that a locking mechanism 210 is not actuated upon a
displacement of the flap 15 to a ventilation position. The smaller the distance G1
sets in the maximum ventilation position, the smaller the free travel of the linking
mechanism 211 can be. In order to provide a wide enough first air passage 7 adequate
for a good air circulation capacity, the hinged structure 30 is adapted so that the
distance G1 sets greater than 5 mm in the maximum ventilation position, and more preferably
not less than 8 mm. Thanks to the first and second air passages 7 and 8, a subtantial
flow F of fresh air incoming through the ventilation passage may enter down into the
room to ventilate (FIG. 2).
[0014] As represented in FIG. 3, the support mechanism 3 comprises a first hinged mechanism
20 and a second hinged mechanism 30 linked to each other. The first hinged mechanism
20 comprises a flap bottom hinge member 22 which is secured to the flap 15 and a latching
supporting plate 21 which is hinged to the flap bottom hinge member 22 about a first
axis A1 which extends along the bottom longitudinal edge 15B of the flap. The latching
supporting plate 21 comprises a linking plate 21B which is jointed to the second hinged
mechanism 30. The first hinged mechanism 20 further comprises a latching mechanism
23 adapted to secure the flap onto the latching supporting plate 21 when the flap
is in the locking closed position as well as in a ventilation position. Unlatching
the latching mechanism allows the flap to be pivoted in an unlocking rotary way about
the first axis A1 relative to the latching supporting plate 21, therefore allowing
to actuate and unlock the two locking mechanisms 210.
[0015] The second hinged mechanism 30 is the hinged structure of the support mechanism 3
which allows to displace the closure element 15 to a ventilation position. Said hinged
structure comprises a supporting casing 300 secured to the sash 10, and a first and
a second pivoting arms respectively 31 and 32 which are each pivotally mounted on
the supporting casing 300 and are arranged parallel to each other. The hinged structure
further comprises a link arm 33 arranged so as to form with the first and second pivoting
arms 31 and 32 a sensibly parallelogrammatic hinge structure allowing the link arm
33 to be displaced while remaining sensibly parallel to a predetermined direction.
[0016] When the window assembly is closed and locked, the ventilation and locking system
is in the position as represented in FIG. 3. By pulling the flap 15 with a flap handle
16, a user displaces the flap to the maximum ventilation position in which the parallelogrammatic
hinge structure of the mechanism 30 reaches an abutment spread position, as represented
in FIG. 4 . The parallelogrammatic hinge structure allows a principal part 33A of
the link arm 33 to remain sensibly parallel to the direction of the line P1-P2, i.e.
the line joining two stationary pivot points P1 and P2 of respectively the first and
the second pivoting arms 31 and 32 (FIG. 4). The link arm 33 is hinged to the pivoting
arms 31 and 32 at two mobile pivot points P3 and P4 which correspond to both ends
of the principal part 33A. It is not necessary that the line P3-P4 joining the mobile
pivot points P3 and P4 remains strictly parallel to the line P1-P2. An approximately
parallelogrammatic hinge structure which would present a slight angle between the
two lines P1-P2 and P3-P4 is acceptable.
[0017] The link arm 33 comprises an extension part 33B which is jointed to the linking plate
21B of the first hinged mechanism 20 at a pivot point P7. The first pivoting arm 31
comprises a principal part 31A and an extension part 31B which is jointed to an inclination
arm 34 at a pivot point P5 corresponding to a bottom end of the first pivoting arm
31. The inclination arm 34 is jointed to the linking plate 21B of the first hinged
mechanism 20 at a pivot point P6.
[0018] Between its locking closed position and a ventilation position, the flap performs
a combined rotatory and translatory displacement which has a rotatory component R1
in a way somewhat opposite the unlocking rotary way and a translatory component T1
which further moves the flap away from the ventilation passage 5 (FIG. 1). The translatory
component T2 is performed by the parallelogrammatic hinge structure through the link
arm 33 which is globally displaced like following a translation.
[0019] The rotatory component R1 is performed through the extension part 31B of the first
pivoting arm 31. Upon rotation of the first pivoting arm 31, the pivot point P5 rotates
around the pivot point P4 following an arc of circle, which entails through the inclination
arm 34 a rotary motion of the pivot point P6 relative to the pivot point P7. Therefore,
the greater is the length of the extension part 31B the greater is the angular amplitude
of the rotatory motion The extension part 33B of the link arm 33 and the inclination
arm 34 form two support arms hinged to the flap through the latching supporting plate
21 at the pivot point P6 and P7 and which move relatively to each other during the
displacement of the flap to a ventilation position, therefore changing the angle between
the line P6-P7 and the stationary line P1-P2. The inclination of the latching supporting
plate 21 being determined by the line P6-P7, the flap 15 supported by the latching
supporting plate 21 therefore swivels relative to the sash 10 through the hinged structure
30 and inclines such that its bottom longitudinal edge 15B sets farther from the ventilation
passage 5 than its top longitudinal edge 15T.
[0020] A support mechanism according to the invention is particularly appropriate for being
used in a ventilation and locking system of the kind here above described in which
the displacement of the closure element to a ventilation position is performed in
a way somewhat opposite the unlocking way. However, the invention is also advantageous
when the support mechanism is used to replace the flap hinges of a classical kind
of ventilation and locking system like the one described in
DE1905074A1 in which the displacement of the closure element to a ventilation position is performed
along a path which is a first part of the displacement path to the unlocking position.
[0021] A support mechanism 3' according to a second embodiment of the invention and used
in a ventilation and locking system of the above mentioned kind is described hereafter
in FIGS. 5 to 11. As represented in FIGS. 5 and 7, a pivoting sash 10 of a window
assembly is equipped with a ventilation and locking system 2' mounted on a top frame
member 11 of the pivoting sash and comprising two identical support mechanisms 3'
which are arranged on both sides of a locking mechanism 410 linked to the closure
element 15.
[0022] The locking mechanism 410 operates according to a principle analogue to the prior
art locking mechanism described in
DE1905074A1. It comprises a slider 412 actuated by the flap 15 through a rigid linking mechanism
413 hinged to the flap and to the slider, and further comprises two locking pins 411
linked to the slider 412 through a lever mechanism not shown. In the locking closed
position of the flap 15 (FIG. 5) as well as in the ventilation position of the flap
(FIGS. 6 and 7), the locking pins 411 remain in a locking position in which they engage
a strike plate 420 mounted on a top frame member 101 of a main frame 100 of the window
assembly. As in the device of
DE1905074A1, the lever mechanism of the locking mechanism 410 is adapted so that when the flap
15 is displaced from its locking closed position to a stable ventilation position,
a corresponding displacement of the slider 412 is performed to a stable intermediate
position without actuating the locking pins 411.
[0023] As represented in FIGS. 6 and 7, the flap 15 sets in a stable ventilation position
provided by the stable intermediate position of the slider 412. The two support mechanisms
3' comprise each a hinged structure 30', which is analogue to the hinged structure
30 previously described in the first embodiment of support mechanism according to
the invention but is arranged inversely. Between its locking closed position and a
ventilation position, the flap performs a combined rotatory and translatory displacement
which has a rotatory component R2 in the unlocking rotary way and a translatory component
T2 which further moves the flap away from the ventilation passage 5.
[0024] Due to its inverse arrangement compared to the first embodiment, the hinged structure
30' inclines the flap 15 so that the first air passage 7 widens more than the second
air passage 8, i.e. the distance G1 sets greater than the distance G2 (FIG. 6). A
first and main part of the flow F of fresh air incoming through the ventilation passage
enters the room through the first air passage 7. A significant second part of part
of the air flow F enters the room through the second air passage 8, which improves
the air flow capacity compared to a prior art device of the kind of
DE1905074A1.
[0025] The hinged structure 30' is arranged so that a further displacement of the flap 15
is allowed from the ventilation position to reach the unlocking position of the flap.
To this end, the slider 412 of the locking mechanism 410 is also allowed to be further
moved from its stable intermediate position to an unlocking position in which the
locking pins 411 of the locking mechanism have been displaced to disengage the strike
plate 420, as represented in FIGS. 8 and 9. Advantageously, both hinged structures
30' are arranged to set in an abutment spread position as represented in FIG. 11 when
the slider 412 reaches its unlocking position, so that the pulling effort exerted
by a user to open the window is distributed to both support mechanisms 3'.
[0026] As represented in FIGS. 10 and 11, the hinged structure 30' comprises the same elements
and provides a same parallelogrammatic hinge structure as in the first embodiment
described here above in reference to FIGS. 3 and 4. The hinge structure therefore
operates in a same manner as explained in the preceding description of the first embodiment.
In particular, as illustrated drawn in dash lines, the principal part 33A of the link
arm 33, which extends between the mobile pivot points P3 and P4, remains sensibly
parallel to the direction of the line P1-P2 defined by the stationary pivot points
P1 and P2. The support arms 33B and 34 are hinged to the flap through a supporting
plate 21' which is permanently secured to the flap.
[0027] It can be noted that in the unlocking position of the flap 15 represented in FIG.
11, i.e. in the abutment spread position of the hinged structure 30' limited by a
stopper 36 which cooperates with the first pivoting arm 31, the pivoting arms 31 and
32 are inclined relative to the plane of the sash. This arrangement provides a large
amplitude of displacement of the flap both in translation and in rotation from the
maximum ventilation position to reach the unlocking position, which is advantageous
to have a sufficient actuation travel of the flap in order to actuate the locking
mechanism 410.
[0028] As represented in FIG. 12, a support mechanism 6 according to a third embodiment
of the invention comprises a hinged structure 40 comprising two support arms 43 and
44 including a first support arm 43 arranged to be displaced in translation only.
Each support arm includes a rack rail part, the rack rail parts being interlinked
with each other through a reduction gear 46 comprising three pinions. The small pinion
which engages a second support arm 44 is secured to a larger pinion which meshes with
a similar pinion engaging the first support arm 43. Therefore, a displacement of the
first support arm 43 over a predetermined travel M1-M2 entails a displacement of the
second support arm 44 over a shorter travel N1-N2.
[0029] The displacement of the first support arm 43 is set according to a translatory motion
T3, whereas the displacement of the second support arm 44 over the travel N1-N2 results
from a combination of the translatory motion T3 and a rotary motion R3 which are performed
simultaneously. The distances between the flap 15 and the frame members 11 and 101
of the closure assembly and the inclination obtained for the flap 15 in the maximum
ventilation position represented in FIG. 13 depend on the length of the first support
arm 43 and on the reduction ration of the reduction gear 46.
[0030] The support mechanism 6 is an alternative to the support mechanism 3 according to
the first embodiment of the invention, although the device 6 is not as compact to
obtain a same displacement of the flap. The device 6 may easily be motorised, for
instance through an electric motor actuating a pinion of the reduction gear 46. Discrete
intermediate ventilation positions may easily be provided, for instance by notches
of the first support arm 43 each adapted to cooperate with a pressure spring secured
to the casing.
[0031] In the first three embodiments previously described, the translatory and rotary motions
for the displacement of the closure element to a ventilation position are performed
simultaneously. However, the present invention does not limit itself to this disposition.
Sequential translatory and rotary motions may be provided for a same result. Furthermore,
the present invention does not limit itself to a displacement of the closure element
including a translatory motion, as illustrated hereafter by a fourth embodiment performing
a sole rotary motion.
[0032] As represented in FIG. 14, a support mechanism 6' according to a fourth embodiment
of the invention comprises a hinge support 51 providing a curved guide path 51A along
an arc of circle forming part of a circle C1 which has a centre O1 remote from the
hinge support 51. The centre O1 is located above the flap 15 at the room side. The
hinge support 51 is suitable for being secured to a frame member 11 of a pivoting
sash 10. The support mechanism 6' further comprises a hinge mobile part 52 hinged
to the hinge support 51, which comprises a curved sliding part 52A adapted to slide
along the curved guide path 51A. Therefore, the hinge mobile part 52 can rotate about
a hinge axis passing by the centre O1.
[0033] The hinge mobile part 52 further comprises a support part 52B on which the flap 15
is mounted. The flap 15 is hinged to the support part 52B of the hinge mobile part,
in order to pivot the flap in an unlocking direction to actuate and unlock at least
one locking mechanism. In a same manner as previously described regarding the support
mechanism 3 according to the first embodiment of the invention, the flap 15 hinged
to the support part 52B can be secured and latched to the support part 52B through
a latching mechanism 23.
[0034] When pulling the flap 15 to the maximum ventilation position as represented in FIG.
15, the flap rotates about the hinge axis 01, and the displacement of the flap to
a ventilation position results from a sole rotary motion. The hinge axis O1 is located
so that a top longitudinal edge of the flap moves away by the distance G1 from a sealing
area of a top frame member 101 of the closure assembly. A first air passage 7 communicating
with the ventilation passage of the closure assembly is therefore created, allowing
a top part of the flow F of fresh air incoming through the ventilation passage to
enter the room through the first air passage 7.
[0035] The support mechanisms according to the four embodiment of the invention previously
described advantageously comprise each a hinged structure which is arranged along
a plane perpendicular to a longitudinal axis of the flap, therefore allowing to mount
the hinged structure inside a relatively narrow supporting casing which is not bulky
in the ventilation passage of the closure assembly. However, the invention is not
limited to such a perpendicular disposition.
[0036] As will be appreciated, the present invention does not limit itself to the embodiments
described here above purely as examples; the invention also extends to other embodiments
covered by the claims.
1. A support mechanism (3; 3'; 6; 6') for a closure element (15) of a ventilation and
