[0001] Corner transmission with snap-in connection for window fittings.
[0002] The present invention relates to a snap-in connection for window fittings, more specifically
to a snap-in connection for the coupling between a corner piece of a window leaf and
a coupler lock or the like.
[0003] Classic window fittings contain leaf fittings and frame fittings which cooperate
with each other for closing and operating the window.
[0004] The leaf fittings traditionally contain a number of sliding slats, rods in technical
jargon, and possibly coupler locks which are slidably mounted in a fitting groove
along the contour of the leaf and which are operated by a rotatable operating crank
which converts the rotation of the crank into a sliding movement of the sliding slats
and coupler locks.
[0005] Depending on the configuration of the window, sliding slats and possibly coupler
locks are located in the vertical and horizontal fitting grooves of the leaf, whereby
for the transmission of the sliding movements of the sliding slats and coupler locks,
corner transmissions are applied in the corners of the leaf. Such corner transmissions
are known e.g. from
FR 2 550 574,
US 2015/0052817 A1 or
CN 105484587 A.
[0006] By the movement of the sliding slats and coupler locks a number of fitting functions
can be activated such as locking cams that can cooperate with locking points on the
frame for closing the window and keeping said window closed.
[0007] In the case of a turn-tilt window or tilt-turn window, a link arm is applied as is
known, which needs to be locked for turning open the window and unlocked for tilting
open the window and simultaneously needs to limit the stroke of the tilting movement,
whereby the link arm is also operated by a cam on a sliding slat or coupler lock.
[0008] Furthermore, in this type of windows it is also necessary to create a hinge function
to allow the window to tilt around a horizontal axis.
[0009] Traditionally, a corner piece with a first leg and a second leg is used in which
a spring assembly is slideably applied and forms a connection between the sliding
slats or coupler locks on both sides of the corner.
[0010] In such classic corner piece during assembly only the first end of the spring assembly
can be precoupled to a sliding slat or coupler lock to subsequently be slid into the
fitting groove together. Said sliding slat or coupler lock with associated spring
assembly are in a neutral position then.
[0011] The second end of the spring assembly is coupled to a sliding slat or coupler lock
by means of a coupling block that is mounted on the end of the spring assembly.
[0012] To couple said second end of the spring assembly to a sliding slat or coupler lock,
the spring assembly of the corner transmission needs to be slid to an extreme position
or coupling position whereby the second end with the coupling block needs to be slid
beyond the corner piece.
[0013] In said coupling position the coupling block has sufficient freedom of movement relative
to the bottom of the fitting groove to be able to move under the coupler lock or sliding
slat and click into a provided recess.
[0014] The spring assembly, with a coupler lock or sliding slat coupled thereto, is slid
back into the neutral position, whereby the coupling block disappears into the corner
piece.
[0015] Coupling or uncoupling the spring assembly with sliding slat or coupler lock can
only take place in the coupling position. During normal operation of the window fittings,
said coupling position is never reached and the coupling block thus continuously and
always remains in the corner piece such that the coupling block cannot unintentionally
uncouple.
[0016] A disadvantage is that said mounting method is labour-intensive and cumbersome.
[0017] Another disadvantage is that the spring assembly needs to be slid from the neutral
position to a coupling position for coupling the second end of the spring assembly
to a sliding slat or coupler lock such that it is impossible to deliver the corner
transmission to a customer in a locked position, which implies that mistakes may occur
when mounting the fittings on the leaf.
[0018] Another disadvantage is that an extra stroke must be provided in the corners to reach
said coupling position. Consequently the corners become bigger, the consequence being
that the smallest executable window also becomes slightly bigger.
[0019] Typically, as described above, the first leg of a corner piece is slid into the fitting
groove up into a position whereby the second leg falls into an adjoining fitting groove.
In principle, after coupling to a coupler lock, the second leg is also more or less
locked.
[0020] A disadvantage is that such lock only suffices for corners under the crank. The corners
above the crank and under the link arm are insufficiently resistant to great loads
such as burglary or wrong operation in this way. Furthermore, such lock allows too
much movement of the corner such that unintentional stroke loss may occur.
[0021] That is why extra separate locking pieces are provided on all corners above the operating
crank.
[0022] A disadvantage is that said locking piece is an extra component to be mounted which
is sometimes forgotten. When said locking piece is forgotten during mounting this
may result in an unstable corner in the long term.
[0023] The purpose of the present invention is to provide one or more solutions to the aforementioned
and other disadvantages.
[0024] The present invention provides the following solution: Corner transmission with snap-in
connection for the perpendicular transmission of the sliding movement of sliding slats
and coupler locks of fittings of a window leaf, whereby the corner transmission comprises
a corner piece with a spring assembly therein which is slideable over the corner,
whereby the corner transmission is provided with a snap-in connection for the coupling
between the spring assembly and the coupler lock and whereby for the coupling between
the spring assembly and the coupler lock a sliding snap-in connection is provided
in the form of a coupling block and whereby the corner piece is provided with a temporary
mounting lock which holds the coupling block in the corner piece during coupling with
the coupler lock, said mounting lock being breakable the first time the fittings are
operated.
[0025] An advantage of this is that consequently the spring assembly no longer has to be
slid into the corner piece when the spring assembly needs to be coupled to a coupler
lock and moreover the coupling block can remain in the corner piece. This has the
advantage that no extra stroke needs to be provided for the corner transmission to
make the coupling. Another advantage is that the corner transmission can be delivered
to the customer in a locked condition.
[0026] An additional advantage is that the coupling block on the end of the spring assembly
and the coupler lock is executed such that the spring assembly can be easily coupled
to the coupler lock by one single sliding movement.
[0027] The temporary lock is such that once the fittings are mounted in the window this
lock can be broken by a first operation of the fittings by rotation of the operating
crank.
[0028] This has the advantage that the coupler lock can only be connected with the corner
piece according to the correct orientation.
[0029] In one embodiment according to the invention the coupling block in a window provided
in the corner piece partially protrudes outwardly along the outer contour of the corner
piece and is inwardly elastically compressible in the corner piece thanks to the bendability
of the spring assembly on which the coupling block is mounted, for which purpose an
opening is provided under the coupling block which interrupts the guide of the spring
assembly. Preferably, the end of the coupler lock to be coupled is provided with a
chamfer in the sliding direction of the coupler lock and adjacent thereto a recess
in the coupler lock for snapping into place the section of the coupling block protruding
from the corner piece.
[0030] The chamfer of the coupler lock forces the spring assembly with coupling block to
bend in the aforementioned opening under the spring assembly. On sliding the coupler
lock further, the coupling block is pushed in even further until it can snap into
place in the provided recess of the coupler lock. From this moment, the coupler lock
is connected to the spring assembly by means of the coupling block.
[0031] Said corner transmission with simple snap-in connection does not comprise extra components
relative to traditional window fittings. As no extra components are required and mounting
is considerably simplified, said snap-in connection has the advantage of being easier
and quicker and thus cheaper than the traditional way of connecting.
[0032] Another advantage is that there is no danger of unintentional uncoupling in both
closed and open or tilted condition of the window.
[0033] Preferably, except on the level of the aforementioned interruption of the guide of
the spring assembly, the spring assembly is fittingly enclosed in the guide such that
the spring assembly cannot bend in said places and consequently the coupling block
cannot unintentionally detach.
[0034] According to a further embodiment according to the invention, the snap-in connection
is a detachable snap-in connection such that after mounting the coupler lock can be
simply detached from the coupling block in case the leaf fittings need to be disassembled.
[0035] To this end an access opening for a tool or the like may be provided in the coupler
lock on the level of the recess in which the coupling block snaps into place such
that the coupling block is accessible to be pushed into the mounted condition of the
window fittings, provided that the coupling block is in the corner piece on the level
of the interruption of the guide for the spring assembly. Preferably, said location
of the coupling block is determined by the temporary lock or by a mark applied on
the corner piece to indicate the position of the coupler lock in which the coupling
block is suitably located.
[0036] On the side of the coupling block that is visible through the access opening in the
coupler lock, a number of profilings or surface roughnesses can be applied. By repeatedly
performing sliding and pumping movements on the profilings of the coupling block using
a suitable tool, for example a screwdriver, it is possible to uncouple the coupling
block from the recess with the coupler lock. After uncoupling, the corner transmission
can be simply slid out of an exposed fitting groove.
[0037] This provides the advantage that it is possible to simply disassemble the fittings
in case of an opened window leaf, but that it is impossible for a burglar to get to
and remove the coupling block in case the window is closed.
[0038] In a practical embodiment according to the invention, the coupling block is mounted
on the spring assembly by means of pegs mounted in passages in the spring assembly.
Furthermore, the coupling block can be provided with one or two chamfers on the level
of the pegs on the front and/or back of the pegs seen in sliding direction.
[0039] In a practical embodiment according to the invention the temporary lock to hold the
spring assembly with the coupling block thereon when snapping in place the coupler
lock is, for example, formed by a break-off peg that is mounted on the corner piece
and that is enclosed in a recess of one of the moving parts of the corner piece or
vice versa. The break-off peg is dimensioned such that it breaks off the first time
the leaf fittings are operated.
[0040] According to another characteristic aspect of the invention, the coupler locks can
already be provided with a locking piece snapped in place thereon before mounting.
Said locking piece snaps in place on the corner piece or on the leaf when the close
position of the window is reached the first time. On leaving the close position the
locking piece uncouples from the coupler lock and remains near the corner, where it
fulfils its locking function.
[0041] This has the advantage that the locking piece can no longer be forgotten during assembly.
[0042] Another advantage is that the assembly is strongly simplified as the locking piece
is simply driven into the corner the first time the fittings are closed and that the
locking piece uncouples from the coupler lock and remains in the corner on leaving
the close position such that the locking piece cannot interfere with the further use
of the fittings.
[0043] The connections between coupler lock and locking piece can be executed in various
ways, for example using weak connections such as snap-ins, pegs or breakable material
weakenings.
[0044] The locking piece can be extended from an exposed fitting groove with a device suitable
for this purpose, such as a screwdriver.
[0045] If relevant the lower corners of the window leaf can be provided with a locking piece.
Said locking piece then contains a press or punching screw that clamps or punches
on a tongue of the fitting groove. In this way the lower corners can also be additionally
locked.
[0046] This has the advantage that the burglar resistance is increased even more whereas
the lifespan of the corner increases and stroke loss is countered.
[0047] The coupler lock and the locking piece can for example be made from synthetic material
such that they can be manufactured from one piece, including the aforementioned material
weakenings.
[0048] With the intention of better showing the characteristics of the invention, a preferred

is described hereinafter, by way of an example without any limiting nature, with reference

[0049] The window fittings 1 shown in figure 1 intended for assembly between a fixed frame
of a window and a leaf for opening and closing the window and for tilting the window.
[0050] For the operation, the window fittings 1 contain an operating mechanism 2, as is
known, for the conversion of the rotational movement of an operating crank (not shown
in the figure) to a translation movement of the ends of the operating mechanism 2.
[0051] Said translation movement is transferred to sliding slats 3 which are slidably mounted
in a fitting groove of the horizontal and vertical profiles of the leaf. For the transfer
of the translation from the horizontal to the vertical sliding slats 3, a corner transmission
5 is mounted on the corners of the leaf.
[0052] The fittings 1 are intended to exercise different functions, including a lock function
for locking the leaf in the frame in a closed condition of the window, whereby locking
cams 6 are provided which in closed condition hook behind locking points 7 and which
on opening the window are slid away from behind the locking points 7.
[0053] According to the invention, the corner transmissions 5 are executed with a corner
piece 8 and a coupler lock 9 couplable thereto.
[0054] The corner piece 8 with coupler lock 9 connected thereto, as shown in figure 2, is
shown in disassembled condition in the upper section of figure 3 and is made from
a corner-shaped housing 10 with a first leg 11 and a second leg 12.
[0055] The housing 10 is composed of a left and a right half which are symmetrical and in
which a guide 13 is provided in the form of a groove with a spring assembly 14 therein
which is slideable over the corner and whereby the spring assembly 14 is connected
at one end to a moving leg 15 of the corner piece 8 which is slidable in the second
leg 12 and whereby the other end is intended for the coupling with the coupler lock
9 via a coupling block 16 in the first leg 11 which is provided on the spring assembly
14 to this end.
[0056] The right half of the corner piece 8 is provided with a break-off peg 17 that is
enclosed in a recess 18 of the moving leg 15 to block the spring assembly 14 for coupling
and is dimensioned such that it breaks off the first time the fittings 1 are operated.
[0057] The second leg 12 is provided with laterally extending ribs 19 with which the second
leg 12 of the corner piece 8 can be slid into a fitting groove up to a position in
which the first leg 11 falls into an adjoining fitting groove.
[0058] Both the moving leg 15 and the coupler lock 9 are provided with toothing 20 at their
free end for coupling a fittings section that is provided with complementary toothing
20, for example a sliding slat 3, which may or may not be in the form of a sliding
slat with control coupling 6a.
[0059] In figures 2 and 3 the corner piece 8 is shown together with a coupler lock 9 which
is provided with lateral extending ribs 19 with which the coupler lock 9 is slideable
in the vertical fitting groove and is provided with an adjustable locking cam 6 that
can cooperate with a locking point 7A which is provided on the frame and is slideable
up to over the coupling block 16 for coupling with the spring assembly 14.
[0060] When the corner piece 8 is not coupled with the coupler lock 9, the coupling block
16 partially protrudes outwardly along the outside of the corner piece 8 and is inwardly
elastically compressible in the corner piece 8 thanks to the bendability of the spring
assembly 14 on which the coupling block 16 is mounted, for which purpose an opening
21 is provided which interrupts the guide 13 of the spring assembly 14.
[0061] As illustrated in figure 4, the coupler lock 9 is provided at the coupled end with
a chamfer 22 in the sliding direction of the coupler lock 9 and adjacent thereto a
recess 23 in which the coupling block 16 is snapped in place. Furthermore, under the
coupling block 16, an interruption is provided in the guide 13 of the spring assembly
14 in which the spring assembly 14 with coupling block 16 can locally bend or be pushed
in toward the inside, which means the side of the corner piece 8 that is mounted against
the leaf.
[0062] As shown in figure 7, the coupler lock 9 on the outside of the corner piece 8 is
provided with a window 24 through which the coupling block 16 is accessible with a
suitable tool, such as a screwdriver.
[0063] Just under the aforementioned window 24, the coupling block 16 is provided with two
profilings 25, as shown in figure 5, with which the coupling block 16 can be detached
again by performing some sliding and pumping movements with the tool on the profilings
25.
[0064] As shown in figure 3, 4 and 6, the coupling block 16 is provided with pegs 26 which
are mounted in passages 27 in the spring assembly 14 and are moreover provided with
a chamfer 28 on the level of the pegs 26, seen in the sliding direction.
[0065] Said chamfer 28 lowers the force for realising the snap-in connection.
[0066] The coupler lock 9 can be equipped with a supplementary locking piece 29 in the extension
of the coupler lock 9, as shown in figures 8 to 11.
[0067] The locking piece 29 and the coupler lock 9 are provided with ribs 19 on their lateral
sides which lie in each other's extension and which can slide in the fitting groove.
[0068] The locking piece 29 can hereby be snapped on the coupler lock 9 by means of a reusable
snap-in connection as shown in detail in figure 9 and 10. Said snap-ins 30 are mounted
on the two lateral sides of the locking piece and hook into recesses 31 provided on
the coupler lock 9.
[0069] The locking piece 29 provides extra strength to the corner and is mostly applied
but not limited to the corners above the operating crank.
[0070] Realising the snap-in connection and assembly of the locking piece 29 in the corner
is very simple and as follows:
Figures 11A to 11D show the different phases in which the snap-in connection and locking
the corner are realised, whereby the phases shown in figures 11A and 11B occur upon
the first assembly of the window fittings 1 on the window leaf, whereas figures 11C
and 11D occur upon using the window fittings 1 when the operating mechanism 2 is operated
the first time.
[0071] Figure 11A shows the corner transmission with corner piece 8 whereby the coupler
lock 9, together with locking piece 29, is already slid over the first leg 11 of the
corner piece 8 in the direction of the arrow, but not yet snapped into place. In this
phase, the spring assembly 14 is still locked with the temporary lock, in this case
a break-off peg 17 as mentioned above. Note here that the locking piece 29 is connected
to the coupler lock 9 by means of snap-ins 30 which are provided on the locking piece
29 for this purpose and hook into snap-in details 31 applied on the coupler lock 9.
[0072] In 11B the coupler lock 9 is slid further over the first leg 11 up to over the coupling
block 16 of the spring assembly 14. The coupling block 16 is now enclosed in the recess
23 provided in the coupler lock 9, such that the spring assembly 14 is now unslideably
connected to the coupler lock 9.
[0073] Upon sliding further, for example by rotating the operating mechanism 2, in the direction
of the arrow of the coupler lock 9, the break-off peg 17 breaks off and the temporary
lock is consequently no longer locked. From hereon the spring assembly 14 can be slid
along the coupler lock 9 connected thereto. Figure 11C shows a slid coupler lock 9
whereby the locking piece 29 on the end of the coupler lock 9 is now driven completely
into the corner. The locking piece 29 now snaps into place on the corner piece 8 by
means of snap-ins 32 which are provided on the locking piece 29 for this purpose and
which hook into snap-in details 33 applied on the corner piece.
[0074] The snap-in connection between the corner piece 8 and locking piece 29 is hereby
stronger than the snap-in connection between locking piece 29 and coupler lock 9.
[0075] On rotating back the operating mechanism 2, the coupler lock 9 is slid back in an
opposite direction, in other words in the direction away from the corner as shown
by the arrow in figure 11D. The snap-ins 30 hereby leave the snap-in details 31 such
that the locking piece 29 uncouples from the coupler lock 9 and the locking piece
29 consequently remains behind near the corner where it fulfils its locking function.
[0076] The corner transmission 5 with snap-in connection may, but does not have to comprise
a supplementary locking piece 29, conversely it is clear that the locking piece 29
can also be provided on a classic coupler lock with classic coupling connection.
[0077] Furthermore, the invention is not limited to window fittings 1 with a turn-tilt of
tilt-turn function but is equally applicable to a window that can only turn or only
tilt.
[0078] The connection between coupling block 16 and spring assembly 14 can be made in all
kinds of ways.
[0079] The end of the spring assembly 14 of the second leg 12 does not necessarily have
to be coupled to a moving leg 15 for the coupling with a sliding slat 3, but could
alternatively be directly connected to the sliding slat 3.
[0080] According to a special aspect of the invention as shown in figure 1, the sliding
slats 3 are applied in three zones, namely one zone vertically under the operating
mechanism 2 and two zones above the operating mechanism 2.
[0081] The sliding slats 3 are, for example, components as specified in the pending Belgian
Patent application
BE202105021 which is considered as being included herein by reference.
[0082] The sliding slats 3 shown in figure 1 do not necessarily have to be applied in relationship
with the corner transmission and snap-in connection according to the invention but
can also be applied in fittings with a classic corner transmission without the snap-in
connection.
[0083] The present invention is by no means limited to the embodiments described as an example
and shown in the figures, but a corner transmission with snap-in connection according
to the invention can be realised in all kinds of forms and dimensions, without departing
from the scope of the invention, as defined in the claims.
