Definitions

  • the present invention relates to window fittings, more specifically to the coupling between a corner piece of a window leaf and a coupler lock or the like.
  • Classic window fittings contain leaf fittings and frame fittings which cooperate with each other for closing and operating the window.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the coupling block 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.
  • 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.
  • Coupling or uncoupling the spring assembly with sliding slat or coupler lock can only take place in the coupling position.
  • 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.
  • a disadvantage is that said mounting method is labour-intensive and cumbersome.
  • 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.
  • 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.
  • 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.
  • the second leg is also more or less locked.
  • 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.
  • FR 2550574 A1 relates to window fittings which consist of a cover rail and a control rod held at the rear of this cover rail and detachably fixed thereto at a predetermined position by means of a guiding piece so as to be able to move when detached in the longitudinal direction.
  • the guide piece In locking engagement the guide piece is attached to the cover rail at the predetermined position by means of security elements being made of a material that can shear or break.
  • the guiding piece connects the control rod with movable parts of the window fittings such as for instance the flexible transmission element of a corner transmission device.
  • US 2015/0052817 A1 and CN 105484587 A both relate to a corner transmission device of a window fitting.
  • US 2015/0052817 A1 discloses a locking system including a corner transmission device of a window fitting and lock points along a vertical side as well as the top of a window.
  • the purpose of the present invention is to provide one or more solutions to the aforementioned and other disadvantages.
  • a corner transmission for fittings is provided for the perpendicular transmission of the sliding movement of sliding slats and coupler locks of the fittings, whereby the coupler locks are already 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 coupler lock reaches a lock position the first time.
  • the lock position is a predetermined position in the stroke of the coupler lock which is reached by sliding the coupler lock by rotating the operating crank.
  • the locking piece is near the corner, when the coupler lock is in the lock position.
  • the lock position may coincide with an end of the stroke of the coupler lock but the invention is not limited to this.
  • the lock position of the coupler lock can be reached by rotating the operating crank in a predetermined position. Said position may coincide with the close position, or the tilt position, or the turn position of the window. On leaving the lock position, the locking piece uncouples from the coupler lock and remains near the corner, where it fulfils its locking function.
  • 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.
  • connection 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.
  • the locking piece can be extended from an exposed fitting groove with a device suitable for this purpose, such as a screwdriver.
  • 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.
  • the coupler lock and the locking piece can for example be made from synthetic material or a metal alloy like zamak such that they can be manufactured from one piece, including the aforementioned material weakenings.
  • 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.
  • 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.
  • 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.
  • sliding slats 3 which are slidably mounted in a fitting groove of the horizontal and vertical profiles of the leaf.
  • a corner transmission 5 is mounted on the corners of the leaf.
  • 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.
  • the corner transmissions 5 are executed with a corner piece 8 and a coupler lock 9 couplable thereto.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the coupling block 16 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Said chamfer 28 lowers the force for realising the snap-in connection.
  • 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 .
  • 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.
  • 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.
  • the locking piece 29 provides extra strength to the corner and is mostly applied but not limited to the corners above the operating crank
  • FIG. 11C shows a coupler lock 9 slid up into a lock position 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.
  • 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.
  • the coupler lock 9 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 fulfills its locking function.
  • the locking piece 29 can also be provided on a classic coupler lock with classic coupling connection.
  • 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.
  • connection between coupling block 16 and spring assembly 14 can be made in all kinds of ways.
  • 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.
  • 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.
  • 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.
  • 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.
