The
invention relates to a window or a door, as claimed in the preamble of claim 1.
The DE
195 14 051 discloses doors as well as side-hung windows or bottom-hung windows,
the locking mechanisms of which are actuated electromagnetically for locking
the leaf into the blind frame. The movement of a swivel lock into its lock
position, in which said lock engages in a recess in the door leaf, takes place
under the influence of a spring force on the swivel lock, whereas the swivel
lock is opened or rather disengaged electromagnetically while simultaneously
tensioning the spring.
In
addition, there also exist doors, where several locking elements are actuated
jointly by an electric motor, so that a gear, connecting the locking elements,
is necessary.
Doors
have lower requirements with respect to tightness than windows, since there is
no circumferential sealing plane in the area of the floor, so that for doors it
is sufficient if the sealing edge of the leaf rests against the seals of the
blind frame.
In
contrast, the sealing requirements imposed on windows is higher owing to the
installation at exposed altitudes (high rise buildings, mountain peaks, etc.).
That is, a certain clamping force ought to be exerted on the perimeter seals
between the blind frame and the casement frame.
When the window casement is closed, this clamping force has to be overcome, a feature that is not possible with the means described in the prior art, especially in the DE 195 14 051. The sealing contact pressure is necessary for the requirement of classifying windows in accordance with the standard for tightness and pelting rain resistance.
The
invention is based on the problem of providing a window or a door with an
improved electromechanical locking function.
The
invention solves this problem with the subject, disclosed in claim 1.
Advantageous
embodiments are disclosed in the dependent claims.
According
to the characterizing part of claim 1, each locking element exhibits its own
electromechanical drive mechanism and/or the locking elements are configured in
such a way that, when the window is closed, they are displaced in relation to
one another perpendicularly to the pane plane, thus pressing the leaf against
the blind frame with a predetermined contact force.
Such an
electromechanical drive at each locking element constitutes an inexpensive
solution, which makes it possible to dispense with gear connections between the
individual locking mechanisms.
This
feature includes advantageously an alternative, which may also be viewed
independently and which ensures in a simple way that, when locking, a leaf is
displaced perpendicularly to the pane plane and the leaf plane and is pressed
against the blind frame with a predetermined contact force. According to this
alternative, however, when the window is opened or closed, the window or the
door does not exhibit its own drive in order to move the leaf, but rather only
a locking mechanism, which engages when the leaf has already been closed
manually (or, under some circumstances, also closed separately
electromechanically), and a corresponding locking command is sent to an
operating element.
Preferably
the locking elements are configured in such a manner that the time for locking
upon closing the leaf is longer than the time for unlocking prior to opening
the leaf, a feature that has a very beneficial effect on operating the window.
In
itself arbitrary operating elements can be employed. However, according to
another alternative, an especially preferred operating element is a handle,
which is mounted on the leaf and exhibits a grip piece, which can be moved—in
particular, can be turned—into a number of gripping positions on the leaf, said
gripping positions corresponding to the various operating positions of the
leaf. The handle exhibits switching elements and/or sensors; and the handle is
connected in a wireless manner or by means of electric lines to the
electromechanical locking elements between the leaf and the blind frame and/or
with electromagnetic or electromechanical functional elements, in particular
coupling elements, for at least one or more of the fittings.
It is
especially preferred that the handle comprising the locking elements and/or the
fittings is not connected by means of mechanical elements, like a gear, but is
designed for manual opening and closing of the leaf.
Each
locking element exhibits preferably an electromechanically driven locking
slide—preferably on the blind frame and/or on the leaf—, which is designed for
engaging behind a corresponding locking abutment on the leaf and/or on the
blind frame. The abutment may be constructed as a closing roller or as a
stationary bolt.
To
reach a predetermined closing force, at least one of the locking slides is
provided preferably with a control curve, in particular a tightening slope,
which is configured for the purpose of moving, on extending out the locking
slide, the stationary locking abutment and, thus, the leaf in the direction of
the blind frame, and for the purpose of locking said locking abutment into the
blind frame with a predetermined force.
According
to another alternative, the locking slide exhibits a projection with a
predetermined reach; and the moveable locking slide can be extended so far that
the stationary locking abutment reaches a position, in which it slides past the
projection so that the leaf in this position may disengage extremely fast from
the blind frame.
According
to another advantage alternative, which is supposed to enable an extremely fast
unlocking, the electromechanical drive mechanism exhibits an unlocking spring.
The
electromechanical drive mechanism is designed preferably for the purpose of
moving the locking slide and putting the unlocking spring under tension.
The
tensioning of the unlocking spring may be carried out in a simple way by means
of an eccentric arrangement together with the movement of the locking slide.
According
to a structural alternative, which shall be realized in a simple way, the
eccentric arrangement exhibits an eccentric pin, moving on a circular path.
The
drive mechanism comprises preferably a drive housing, which accommodates an
electric motor and a gear and preferably the unlocking spring, in particular a
helical spring.
The
unlocking spring envelops preferably the locking slide and is braced against
two stops.
According to an advantageous alternative, the eccentric pin acts on a radial stop on or around the locking slide, so that, as said eccentric pin moves initially on its circular path for locking, it advances the locking slide outwards out of the drive housing until, as said pin continues to traverse the circular path in the unlocking process, it reaches a position, in which the tension on the unlocking spring may be relaxed.
At the
same time an advantageous design is offered in such a way that after traversing
less than half the circular path of the eccentric pin about the center point,
the locking position is reached and that as the eccentric pin continues to
traverse the circular path, the moveable locking slide extends further until it
reaches a position, in which the leaf in turn may disengage very quickly from
the blind frame.
The
invention makes realizable a leaf locking, which is linked electrically
together in a point-by-point manner, and preferably also such an actuation of
the fittings that at least the fixing of the fittings for a turn, tilt and/or
lock position and of the locking mechanisms for a lock position, is carried out
in a force actuated manner, i.e., by means of a motor. The unlocking or rather
disengagement of the fittings may also be carried out by means of a motor or
spring assistance.
Kinematic
reversals, e.g., with control curves at the locking abutments, can also be
realized. Similarly the electromechanical drive may be put in the leaf and the
abutment on the blind frame.
The
invention is described in detail below by means of the embodiments with
reference to the drawings.

number of gripping positions;

Figure
1 depicts a turn-tilt window 1 comprising a blind frame 2 and a leaf 23, which
exhibits here a casement frame 3 and holds a pane 24.
The
turn-tilt window is arranged so as to be tiltable about a first axis x,
oriented horizontally in the standard installation position, and is arranged so
as to be rotatable about a second axis y, which is vertical here.
For
this purpose the window 1 exhibits a turn and tilt bearing 4, a disconnectable
rocker bearing 5, and a pivot bearing 6, as the fittings, which are intended
for moving the leaf and are located between the blind frame 2 and the casement
frame 3. Said pivot bearing is constructed as a turn hinge and is fastened on
the casement frame 3 and is fixed in a disconnectable manner in the blind frame
2. In addition, there is also a deployment device 7.
Depending
on whether the window is tilted or turned or whether it is closed, these
fittings or rather in this case these bearings are or are not in their
functional position. Therefore, during tilting movements, the rocker bearing 5
is in its functional position; and the pivot bearing 6 is not. In contrast,
during turning movements the pivot bearing 6 is in its functional position; and
the rocker bearing 5 is not.
The
turn hinge 6 is coupled in a disconnectable manner, as a function of its
design, to the blind frame or to the casement frame in the lock position of the
window and in the swivel position about the Y axis and is rigidly disposed
correspondingly on the casement frame or blind frame. In the latter case the
pivot bearing 6 and the deployment device 7 form a unit.
Furthermore,
in the turn-tilt window, depicted in Figure 1, a subgroup of the fittings,
which are necessary for realizing the moveability between the leaf and the
blind frame—in this case the rocker bearing 5 and the pivot bearing 6 as well
as also the deployment device 7—has functionally at least one electromechanical
functional element 10, 11 or 12, with which the fittings 5, 6 and 7 are coupled
into or uncoupled out of their functional position, as function of the
actuation in their functional position, in order to move the leaf 23 either
into its tilt position or into its turn position or to lock the leaf 23 into
its lock position in the blind frame 2.
The
“activation” and/or “deactivation” of the rocker bearing 5 and/or the pivot
bearing 6 is/are carried out by way of electromechanically acting coupling
elements 10, 11. The electromechanical element 10 controls and/or couples the
rocker bearing 5 between the leaf lock position and the leaf turn position
about the X axis, on the one hand, and the disengagement position for the
swivel position of the leaf about the Y axis.
The
electromechanical element 11 ensures, on the one hand, the fixing of the pivot
bearing 6, which is disposed on the leaf 23, in the blind frame 2 in the leaf
position and the swivel movement about the Y axis and, on the other hand,
releases the pivot bearing 6, when the leaf 23 is positioned in the X axis.
Furthermore,
the edge of the window has a deployment device 7, as another moveable fitting,
located between the blind frame 2 and the casement frame 3. Said deployment
device is used for defining the tilt position of the leaf in relation to the
blind frame 2. The deployment device 7 may also be connected to the turn hinge
6. Then the turn hinge 6 is attached to the blind frame 2 and can be coupled to
the leaf 23 by means of the deployment device. Furthermore, the deployment
device 7 may be used optionally for opening and closing the turn-tilt window in
and out of the tilt position by way of elements (not illustrated here), like an
electric motor and a gear—in particular a chain or cable, to be attached to the
deployment device.
The
functional element 11 ensures the disengagement of the pivot bearing 6 at the
leaf 23 during the pivot movements about the Y axis in its functional position.
During the tilt movements, in contrast, the pivot bearing is disabled in its
deactivated position. The other functional elements 10, 12 work in a manner
analogous to the rocker bearing 5 and the deployment device 7, the movements of
which are either deactivated and/or blocked or released, for example, by means
of electromechanically operated coupling elements comprising moveable bolts or
the like.
Locking
elements 8, 9, located between the blind frame 2 and the casement frame 3, are
arranged in or on the rebated area, existing between said blind frame and the
casement frame, point-by-point or rather only at individual spots of the
rebated area that are set apart from each other. Said locking elements bridge
the rebated area and are used to lock the leaf 23 into the blind frame 2 in the
lock position of the window. There are here by way of example three locking
elements on the edge of the leaf on the side of the turn hinge 6 and the edge
of the casement frame 3, which is located opposite the turn hinge 6. It is also
conceivable to provide additional locking elements 8, 9 on the other sides,
especially on the top side and the bottom side of the window and/or a different
number of locking elements 8, 9. In this case, the locking elements 8, 9 can be
actuated in a wireless manner or by means of electric lines (cannot be
recognized here) and exhibit an electromechanically acting locking element. An
electromechanical locking element, like a locking slide, is preferred in order
to generate an adequate amount of locking force, optionally in connection with
additional translation elements, like tightening slopes, eccentrics, expanding
wedges or the like. Therefore, the locking procedure shall be carried out
preferably by means of the electromechanical drive and the unlocking procedure,
according to an alternative, by means of an unlocking spring, since in general
when a window is opened, there is less time available than when closing and
subsequently locking said window.
A
handle 13, which is mounted on the casement frame 3 and exhibits a grip piece
25, which can be moved—in this case turned—into different gripping positions on
a shaft in relation to the blind frame 3, is used as the actuating element for
the leaf 23.
The
gripping positions of the handle 13 are to be distinguishable by a user on
visual inspection. In the gripping positions, which differ from each other by a
number of angles, in this case 90 deg., and are provided here by way of example
for a turn-tilt window, the leaf 23 is either locked, or can be tilted or turned.
The
handle 13 is used here for the purpose of both tilting and turning the window,
thus for generating the mechanical force to move the leaf 23 in relation to the
blind frame. However, the handle 13 is not used, as otherwise typical, for the
purpose of actuating the locking elements and/or the fittings by means of a
mechanism. Rather, this task is carried out here by means of electrical lines
or in a wireless manner without any mechanical connection to the fittings 4, 5,
6, 7, in that the switching position of the handle 13 is registered by way of a
detection device, like switching contacts or sensors (e.g., reed contacts) and
is used for actuating the electromagnetically or electromechanically acting
locking and functional elements, in order to use the fittings in either the
tilting functional position or the turning functional position or to close the
window.
In
Figure 1 the handle 13 is configured in such a way that the downwards pointing
gripping position is equivalent to the lock position of the window, in which
all of the locking and functional elements 8, 9; 10–12 are located in the
locking and/or lock position.
In
contrast, the gripping position 16 corresponds to the option of displacing the
leaf 23 into its turn position. In this gripping position the locking elements
8, 9 and the functional element 10 for the rocker bearing 5 are unlocked.
However,
in the turn position—in this case where the gripping position of the handle is
pointing upwards—the leaf 23 may be turned so that in this gripping position
the locking elements 8, 9 and the functional element 11 for the pivot bearing 6
are unlocked.
The
handle 13 is not connected to the locking elements 8, 9 or the fittings by
means of any mechanical elements, like a gear, especially a connecting rod assembly.
Since a mechanical gear connection between the handle and the locking elements
and the fittings is dispensed with, the cost of manufacturing the window is
reduced, on the one hand; and, on the other hand, it offers the option of
transmitting the registered gripping positions to a higher ordered monitoring
unit (not illustrated here) by means of a wireless connection or some other
connection of the grip piece or the switching and/or sensor elements, which are
assigned to the grip piece, so that it is possible, for example, to register
and to monitor by means of a central station the position of the window of a
building without any additional sensor technology between the blind frame and
the casement frame.
According
to an advantageous alternative of the invention, the switching and/or sensor
elements of the handle 13 as well as optionally other electric or electronic
components, like interface components to a databus and/or energy bus of a
building’s automation system, may be housed in a grip housing 14—in this case,
formed as a rosette in the outward direction without negatively modifying the
visual impression, compared to conventional, purely mechanically acting
handles.
As an
alternative, it is also conceivable (not illustrated here) to house an electric
circuit for the handle 13 in or in the vicinity of the handle 13, thus in the
rebated area, a chamber or in a recess of the casement frame.
The
handle 13 enables, on the one hand, the customary manipulation of the window
and, on the other hand, is used—depending on the configuration—as a switching
and/or information module owing to its electronics comprising sensor and/or
switching elements.
Figure
2 depicts another example of a handle 18 for a turn-tilt window. The handle,
depicted in Figure 2, exhibits a loop-type grip 19, which can be turned and/or
tilted, like a rocker, into different gripping positions in relation to a grip
housing 22, fastened to the leaf 23. In the gripping position, bearing the
reference numeral 19, the window is closed; in the position bearing the number
20, it may be displaced into its tilt position; and in the position of the
handle 18, bearing the number 21, said window may be displaced into its turn
position.
In the
case of an embodiment as a bottom-hung or side-hung window, only two gripping
positions are necessary.
The
number of locking elements 8, 9 varies as a function of the size of the leaf.
In a
turn-tilt window of a smaller model, at least one of the locking elements 8 is
necessary. Preferably one of the locking elements 8, 9 is provided on the
grip-sided vertical frame strut 29. In the case of larger window casements and
as a function of the window installation conditions the four frame struts 29–32
of the casement frame 3 may have additional locking elements, which lock the
leaf virtually point-by-point or rather spot-by-spot.
The
connection of the individual locking elements 8, 9 as well as the
electromechanical elements 7, 8 and 9 for actuating the fittings 4 and 5 is
carried out exclusively by means of electric connections, based on a switching
control element for selecting the respective function of the window in the
lock, turn or tilt position in the case of turnable or tiltable windows and/or
the lock and swivel position in the case of side-hung, bottom-hung or top-hung
windows.
Figure
3 is a sectional view of a frame of a window comprising a blind frame 2 and
casement frame 3. One of the locking elements 8, 9, which can be operated
electromechanically, is represented schematically in the rebated area 26. Each
locking element 8, 9 comprises an electromechanically driven, moveable locking
slide 27, which can be moved in the direction of the pane plane in the
direction of the casement frame 23 and in its locking position engages behind a
locking abutment 28, like a roller or a bolt, which is stationary at the leaf
or rather cannot be moved in relation to the leaf 23.
Figure
4 is a schematic drawing of such a locking mechanism 8' in various operating
positions.
Figure
4 depicts an electromechanical drive mechanism 33, which is shown merely as a
schematic and which exhibits an electric motor and preferably a gear (not
illustrated here in detail), connected on the outgoing circuit of said electric
motor. This drive mechanism 33 is disposed preferably on the blind frame (or,
as an alternative, on the leaf).
According
to Figure 4, the locking slides 27 are provided with control curves, especially
tightening slopes 34, in such a way that, on locking with a predetermined
force, the leaf 23 is pulled over a path “c” in the direction of the blind
frame 2, so that the leaf 23 rests flush against the blind frame 2 with a
predetermined force.
The
gear enables the linear movement of the locking slide 2 into its axial
direction or rather in the direction of the corresponding window section—here
the leaf 3—as well as in the direction of the locking abutment 28, which is
fixed in position on the moveable leaf (not illustrated here).
The
side of the locking slide 27 that faces the locking abutment 28 exhibits a
control curve (here a tightening slope 34), which may also be configured on a
projection 35, which is molded radially to the actual locking bolt and extends
only over a portion, in particular an end area of the locking slide 27.
The
function of this arrangement is as follows:
When
the window is closed, the locking slide 27 is extended out of a retracted
position (Figure 4a) from the blind frame 2 in the direction of the casement
frame 3, until the locking slide 27 rests with its tightening slope 34 against
the outside radius of the locking abutment 28 (Figure 4b). If the locking slide
27 is extended further, the locking abutment 28 on the leaf 3 as well as the
leaf 3 itself are pulled perpendicularly to the pane plane in the direction of
the blind frame 2, until a locking position is reached, in which the path of
the tightening slope 34 is totally traversed, so that the lock position may
also be retained (locking position of Figure 4c), when there is no current flow
to the motor.
According
to an alternative, the lock path along the tightening slope 34 may be traversed
in reverse for the purpose of unlocking (not illustrated).
However,
to open the leaf as fast as possible, it is also conceivable to extend the
locking slide 27 further until said slide reaches a position, at which it
slides past the projection 35 with the tightening slope 34, so that the leaf 23
may disengage extremely fast from the blind frame 2 (Figure 4d).
When
the window is locked, the path “a”, which is to be traversed linearly by the
locking slide 27 in its direction of displacement, is clearly longer than the
path “b”, to be traversed when unlocking prior to opening (ratio of a to b is
significantly greater than 2 to 1), so that even the time that is required
until the window is unlocked and may be opened after actuating the operating
element, especially after turning the handle 13, is less than the time that is
required by the drive to lock the window after, for example, manually closing
and then turning the handle 13. This feature is advantageous, because
especially the opening procedure is always supposed to be fast, whereas the
user is not troubled if it takes longer to lock after closing the window or
rather after pressing the leaf against the blind frame 2.
Figure
5 shows an alternative embodiment. In this case the locking procedure is
carried out in a manner analogous to that in Figure 4, but the unlocking is
done by means of an unlocking spring 36.
Therefore,
a drive housing 37 for the electric motor and a gear is configured in such a
way that it also accommodates the unlocking spring 36, in particular a helical
spring.
The
unlocking spring 36 envelops the locking slide 27 and is braced against two
stops 38, 39, which envelop concentrically the locking slide 27. Therefore, one
of the stops 38 envelops disk-like the locking slide 27 and is fixed axially to
the same; and the other is constructed as a housing wall 40 of the drive
housing 34, through which the locking slide 27 extends moveably. The projection
41, protruding beyond the drive housing 37, has a head piece 42 of
predetermined length, which in turn is provided with the tightening slope 34.
The
locking procedure is carried out as in Figure 4, but an eccentric mechanism
comprising an eccentric pin 43 is configured in the drive housing 37 on the end
of the locking slide 27. Said eccentric pin moves over a circular path 44; and
on closing, it acts on a radial stop 45 on or around the locking slide 27,
which is connected stationarily to the locking slide 27, so that the eccentric
pin advances via the stop 45 the locking slide 27 outwards out of the drive
housing (as far as up to the locking position of Figure 5c).
If the
eccentric pin is moved further, it slides past the edge of the stop 45, so that
the locking abutment 28 in turn is disengaged, so that the unlocking spring 46
may relax.
In
contrast, the circular path 44 of the eccentric pin 43 is measured and
adjusted, according to Figure 5b, in such a manner that the closing position is
reached as early as after less than half the circular path 44 and that, when
said eccentric pin continues to traverse the circular path 44, the locking
slide 27 is extended further until it in turn reaches a position, at which the
head piece 42 is disengaged so that the leaf 23 in turn may quickly disengage
from the blind frame 2 (Figure 5d).

the locking of the locking slide and the tensioning of the unlocking spring
(36) is carried out by means of an eccentric arrangement.
12. Window
or door, as claimed in any one of the preceding claims, characterized in that
the eccentric arrangement exhibits an eccentric pin, (43), moving on a circular
path.
13. Window
or door, as claimed in any one of the preceding claims, characterized in that
there is a drive housing (37), which accommodates an electric motor and a gear
and preferably the unlocking spring (36), in particular a helical spring.
14. Window
or door, as claimed in any one of the preceding claims, characterized in that
the unlocking spring (36) envelops the locking slide (27) and is braced against
two stops (38, 39), which can be moved in relation to each other and of which
one is fixed in position at the locking slide (27).
15. Window
or door, as claimed in any one of the preceding claims, characterized in that
the eccentric pin (43) acts on a radial stop (45) on the locking slide (27), so
that, when said eccentric pin moves initially on its circular path (44) for
locking, it advances the locking slide outwards out of a drive housing (37)
until a position is reached, in which the tension on the unlocking spring (36)
may be relaxed for unlocking.
16. Window
or door, as claimed in any one of the preceding claims, characterized by such a
configuration that after traversing less than half the circular path (44) of
the eccentric pin (43), the locking position is reached and that as the
eccentric pin continues to traverse the circular path (44), the moveable
locking slide (27) extends further, until it reaches a position, in which it
slides past a head piece (42) at the locking slide (27) with the tightening
slope, so that the leaf may disengage from the blind frame (2).
17. Window
or door, as claimed in any one of the preceding claims, characterized in that
at least one of the locking elements (8, 9) is provided on the grip-sided
vertical frame strut (29).
18. Window
or door, as claimed in any one of the preceding claims, characterized in that
one or the other frame struts (29–32) of the casement frame (3) has/have
additional locking elements, which lock the leaf point-by-point or rather
spot-by-spot.
Abstract
A
window or door comprising a circumferential blind frame (2) and a leaf (23)
with a surface element (24), which can be pivoted about one or more axes (X
axis, Y axis) in relation to the blind frame, as well as comprising fittings
(4–7), located between the leaf (23) and the blind frame (2), which are used
for moving the leaf in relation to the blind frame, as well as comprising
electromechanically actuated locking elements (8, 9) for locking the leaf into
the blind frame, is characterized in that each locking element (23) exhibits
its own electromechanical drive, and/or that the locking elements (8, 9) are
configured in such a way that, when the window is closed, they are displaced in
relation to one another perpendicularly to the pane plane, thus pressing the
leaf against the blind frame with a predetermined contact force.
