Description

Technical Field

[0001] This invention relates to window fittings, and more particularly to the connection between corner fittings of window slats and connector locks, etc. Background Technology

[0002] Traditional window fittings include slat fittings and frame fittings that work together to close and operate the window.

[0003] Traditionally, window slat fittings include multiple sliding slats, rods in technical terms, and possibly connector locks, which are slidably mounted in fitting recesses along the profile of the window slat and operated by a rotatable operating crank that converts rotation of the crank into sliding movement of the sliding slats and connector locks.

[0004] Depending on the window configuration, the sliding slats and possible connector locks are located in the vertical and horizontal mounting slots of the window slats, thus corner drive devices are applied at the corners of the window slats in order to transmit the sliding movement of the sliding slats and connector locks.

[0005] By moving the sliding slats and the connector lock, many accessory functions can be activated, such as a locking cam that can engage with locking points on the frame to close the window and keep the window closed.

[0006] In the case of a rotary-tilt window or a tilt-rotate window, a linkage arm is used as is known; the linkage arm needs to be locked to rotate open the window and needs to be unlocked to tilt open the window, while the travel of tilting movement needs to be limited, so that the linkage arm is also operated by a cam locked on a sliding bar or connector.

[0007] Furthermore, in this type of window, it is necessary to create a hinge function to allow the window to tilt around the horizontal axis.

[0008] Traditionally, corner pieces with a first leg and a second leg are used, wherein a spring assembly is slidably applied to the corner piece, and the spring assembly forms a connection between sliding strips or connector locks on both sides of the corner.

[0009] In such conventional corner fittings, during assembly, only the first end of the spring assembly can be pre-attached to the sliding strip or connector lock, and then together they slide into the mounting slot. The sliding strip or connector lock with the associated spring assembly is then in the intermediate position.

[0010] The second end of the spring assembly is connected to the sliding strip or connector lock by means of a connecting block mounted on the end of the spring assembly.

[0011] In order to connect the second end of the spring assembly to the sliding strip or the coupling lock, the spring assembly of the corner drive needs to slide to the limit position or the connection position, whereby the second end with the connecting block needs to slide beyond the corner piece.

[0012] At the connection position, the connecting block has sufficient freedom of movement relative to the bottom of the mounting slot, allowing it to move under the connector lock or sliding strip and engage in the provided groove.

[0013] The spring assembly with a connector lock or sliding strip connected to it slides back to the middle position, whereby the connecting block disappears into the corner piece.

[0014] The engagement or disengagement of the spring assembly with the sliding strip or connector lock can only occur in the engaged position. During normal operation of the window fitting, the engaged position is never reached, and the connecting block is therefore continuously and always held in the corner piece, preventing accidental disengagement.

[0015] The disadvantage is that the installation method is labor-intensive and relatively troublesome.

[0016] Another drawback is that the spring assembly needs to slide from the middle position to the coupling position in order to connect the second end of the spring assembly to the sliding strip or connector lock. This makes it impossible to deliver the corner drive in the locked position to the customer, which means that errors may occur when installing the fittings onto the window slats.

[0017] Another drawback is that extra travel must be provided at the corners to reach the connection points. Therefore, the corners become larger, resulting in a slightly larger minimum executable window.

[0018] Typically, as described above, the first leg of the corner piece slides into a position within the mounting slot, and the second leg then falls into the adjacent mounting slot from that position. In principle, after being engaged with the connector lock, the second leg is also more or less locked.

[0019] The drawback of traditional solutions is that these locks only apply to the corners below the crank. The corners above the crank and below the connecting rod arm are insufficient to withstand heavy loads, such as theft or other misoperations. Furthermore, these locks allow excessive movement of the corners, potentially leading to unexpected loss of travel.

[0020] This is why additional individual locking elements are provided at all corners above the crank.

[0021] The disadvantage is that the locking element is an additional component to be installed and is sometimes forgotten. When the locking element is forgotten during installation, this can lead to long-term instability at the corners. Summary of the Invention

[0022] The purpose of this invention is to provide one or more solutions to the above and other disadvantages.

[0023] In one aspect of the invention, a corner drive device with a snap-fit ​​connection is provided for the sliding movement of a connector lock of a sliding slat and a window leaf fitting, wherein the corner drive device includes a corner piece having a spring assembly that can slide on the corner; wherein the corner drive device is provided with a snap-fit ​​connection for connecting the spring assembly and the connector lock; and wherein a sliding snap-fit ​​connection is provided in the form of a connecting block for the connection between the spring assembly and the connector lock; and wherein the corner piece is provided with a temporary mounting lock that holds the connecting block in the corner piece during connection with the connector lock, the temporary mounting lock being destructible during the first operation of the fitting.

[0024] The advantage of this approach is that when the spring assembly needs to be engaged with the connector lock, it no longer needs to slide into the corner piece, and the connecting block can remain in the corner piece. This eliminates the need for additional travel for the corner drive to engage. Another advantage is that the corner drive can be delivered to the customer in the locked state.

[0025] Another advantage is that the connecting block and connector lock at the end of the spring assembly are configured to allow the spring assembly to be easily connected to the connector lock by a single sliding movement.

[0026] The temporary lock allows the lock to be disengaged by turning the operating crank once the accessory is installed in the window.

[0027] The advantage of this is that the connector lock can only be connected to the corner piece according to the correct orientation.

[0028] In one embodiment of the invention, the connecting block in the window is disposed in the corner piece and partially protrudes outward along the outer contour of the corner piece. Due to the flexibility of the spring assembly on which the connecting block is mounted, the connecting block can be elastically compressed inward within the corner piece. For this purpose, an opening is provided below the connecting block, which interrupts the guide of the spring assembly. Preferably, the end of the connector lock to be connected is chamfered in the sliding direction of the connector lock, and a groove is provided in the connector lock adjacent to the chamfer for engaging the connecting block from the protruding portion of the corner piece.

[0029] The chamfer of the connector lock forces the spring assembly with the connecting block to bend within the aforementioned opening located below the spring assembly. As the connector lock slides further, the connecting block is pushed in further until it engages with a groove provided in the connector lock. From this point onward, the connector lock is connected to the spring assembly by means of the connecting block.

[0030] Compared to traditional window fittings, the corner drive with its simple snap-fit ​​connection does not require any additional parts. Because no extra parts are needed and installation is greatly simplified, the snap-fit ​​connection is easier, faster, and cheaper than traditional connection methods.

[0031] Another advantage is that there is no risk of accidental detachment whether the window is closed, open, or tilted.

[0032] Preferably, in addition to the aforementioned interrupted layer of the guide of the spring assembly, the spring assembly is also suitably enclosed in the guide so that the spring assembly cannot be bent in the position and therefore the connecting block will not be accidentally disassembled.

[0033] According to another embodiment of the invention, the snap-fit ​​connection is a detachable snap-fit ​​connection, so that if the window leaf fitting needs to be disassembled after installation, the connector lock can be easily removed from the connector block.

[0034] For this purpose, access openings for tools, etc., are provided at the level of a recess in the connector lock; the connecting block engages in this recess, allowing it to be pushed into the installed position of the window fitting, provided the connecting block is positioned in the corner piece at the level of the interruption of the guide for the spring assembly. Preferably, the position of the connecting block is determined by a temporary lock or markings applied to the corner piece to indicate the proper position of the connecting block on the connector lock.

[0035] Multiple contours or surface roughnesses can be applied to the side of the connector block, visible through the access opening in the connector lock. By repeatedly performing sliding and pumping movements on the contour of the connector block using a suitable tool, such as a screwdriver, it is possible to disengage the connector block from the groove with the connector lock. Once disengaged, the corner drive can simply slide out of the exposed mounting slot.

[0036] This offers the advantage that when the window slats are open, the fittings can be easily disassembled; while when the window is closed, it is impossible for a thief to approach and remove the connecting block.

[0037] In a practical embodiment of the invention, the connecting block is mounted on the spring assembly by means of a pin installed in a channel within the spring assembly. Furthermore, viewed from the sliding direction, the connecting block may have one or two chamfers at the front and / or rear of the pin at the pin level.

[0038] In a practical embodiment of the invention, when the connecting block is snapped into place, the temporary lock and the connecting block together secure the spring assembly. For example, the connector lock is formed by a release pin, which is mounted on the corner piece and enclosed in a groove in one of the moving parts of the corner piece, or vice versa. The release pin is sized such that it disengages upon first operation of the window slat fitting.

[0039] In another aspect of the invention, a corner drive device for window fittings is provided for the vertical drive of the sliding movement of the fitting's sliding slats and connector lock, wherein the connector lock has a locking element snapped onto it before installation. When the connector lock first reaches the locked position, the locking element snaps into place on the corner fitting or window slat. The locked position is a predetermined position in the travel of the connector lock, which can be reached by rotating an operating crank to slide the connector lock. Preferably, when the connector lock is in the locked position, the locking element is near the corner. The locked position may coincide with the end of the connector lock's travel, but the invention is not limited thereto. The locked position of the connector lock can be reached by rotating the operating crank at the predetermined position. This position may coincide with the closed position, tilted position, or rotated position of the window. Upon leaving the locked position, the locking element disengages from the connector lock and remains near the corner, where it performs its locking function.

[0040] This has the advantage that locking parts will no longer be forgotten during assembly.

[0041] Another advantage is that when the accessory is closed for the first time, the locking element is simply driven into the corner, and the locking element disengages from the connector lock and remains in the corner when leaving the closed position, so that the locking element does not hinder the further use of the accessory, thus greatly simplifying assembly.

[0042] The connection between the connector lock and the locking element can be performed in various ways (e.g., using a weak connection, such as a snap, a nail, or a weakened part made of fragile material).

[0043] The locking element can be extended from the exposed mounting slot using a device suitable for this purpose (such as a screwdriver).

[0044] If applicable, a locking element can be provided at the lower corner of the window slat. This locking element then includes a clamping or stamping screw that clamps or stamps onto the tongue of the mounting slot. In this way, the lower corner can also be additionally locked.

[0045] The advantages of this are that it further improves anti-theft performance, extends the lifespan of the corners, and offsets travel loss.

[0046] The connector lock and locking element may, for example, be made of a synthetic material or a similar zinc alloy, such that they may be made of a component including the aforementioned material weakening portion. Attached Figure Description

Figure 2 Components. Detailed Implementation

[0048] Figure 1 The window fitting 1 shown is designed to be assembled between the fixed frame of the window and the window leaf for opening and closing the window and tilting the window.

[0049] For operation, the window fitting 1 includes an operating mechanism 2, as is known, for converting the rotational movement of the operating crank (not shown) into the translational movement of the end of the operating mechanism 2.

[0050] The translational movement is transmitted to the sliding strip 3, which is slidably mounted in the mounting slots of the horizontal and vertical profiles of the window slat. To transmit the translation from the horizontal sliding strip 3 to the vertical sliding strip 3, a corner transmission device 5 is mounted on the corner of the window slat.

[0051] Accessory 1 is designed to perform various functions, including a locking function for locking the window leaf in the frame when the window is closed, thereby providing a locking cam 6 that hooks behind the locking point 7 when closed and slides out from behind the locking point 7 when the window is opened.

[0052] According to the present invention, the corner transmission device 5 is performed by the corner piece 8 and the connector lock 9 which can be connected thereto.

[0053] like Figure 2 As shown, the corner piece 8 connected to the connector lock 9 is in Figure 3 The upper part is shown in a disassembled state and is made of a corner-shaped housing 10 having a first leg 11 and a second leg 12.

[0054] The housing 10 is composed of a symmetrical left half and a right half, wherein the guide 13 is provided in the form of a groove, wherein a spring assembly 14 is provided, the spring assembly 14 being slidable on the corner, and thereby one end of the spring assembly 14 is connected to a movable leg 15 of the corner 8 that is slidable in the second leg 12, and the other end is used to connect the connector lock 9 via a connecting block 16 in the first leg 11, the connecting block 16 being provided on the spring assembly 14 for this purpose.

[0055] The right half of the corner piece 8 is provided with a separation pin 17, which is enclosed in the groove 18 of the movable support leg 15 to block the connection of the spring assembly 14, and is sized so that it is disconnected when the accessory 1 is operated for the first time.

[0056] The second leg 12 is provided with a laterally extending rib 19; using the laterally extending rib 19, the second leg 12 of the corner piece 8 can slide into a position in the assembly slot, and the first leg 11 falls into the adjacent assembly slot from this position.

[0057] Both the movable outrigger 15 and the connector lock 9 have teeth 20 at their free ends for connecting to fitting sections (e.g., sliding strips 3) with complementary teeth 20, which may or may not be in the form of sliding strips with control connectors 6a.

[0058] exist Figure 2 and Figure 3 The image shows corner piece 8 and connector lock 9. The connector lock 9 is provided with a laterally extending rib 19, which allows it to slide in a vertical mounting slot. It is also provided with an adjustable locking cam 6, which can engage with a locking point 7A provided on the frame and can slide above the connecting block 16 for connection with the spring assembly 14.

[0059] When the corner piece 8 is not connected to the connector lock 9, the connecting block 16 protrudes outward along the outer side of the corner piece 8; and due to the flexibility of the spring assembly 14 on which the connecting block 16 is mounted, the connecting block 16 can be elastically compressed inward within the corner piece 8. For this purpose, an opening 21 is provided in the guide 13 of the interrupting spring assembly 14.

[0060] like Figure 4 As shown, the connector lock 9 has a chamfer 22 at the connecting end along the sliding direction of the connector lock 9, adjacent to the groove 23; the connecting block 16 is engaged in the groove 23. Furthermore, below the connecting block 16, an interruption is provided in the guide 13 of the spring assembly 14; in this interruption, the spring assembly 14 with the connecting block 16 can be partially bent or pushed inward, the inward side referring to the side of the corner piece 8 that abuts against the window leaf.

[0061] like Figure 7 As shown, the connector lock 9 on the outside of the corner piece 8 is provided with a window 24 through which the connector block 16 can be accessed with a suitable tool (such as a screwdriver).

[0062] like Figure 5 As shown, directly below the aforementioned window 24, the connecting block 16 is provided with two contours 25; using these two contours, the connecting block 16 can be disassembled again by performing some sliding and pumping movements on the contours 25 with a tool.

[0063] like Figure 3 , Figure 4 and Figure 6 As shown, the connecting block 16 is provided with a pin 26 installed in the channel 27 of the spring assembly 14; and furthermore, in the sliding direction, a chamfer 28 is provided on the horizontal surface of the pin 26.

[0064] The chamfer 28 reduces the force required to achieve the snap-fit ​​connection.

[0065] like Figures 8 to 11 As shown, the connector lock 9 may be equipped with an auxiliary locking element 29 in the extension of the connector lock 9.

[0066] The locking element 29 and the connector lock 9 are provided with ribs 19 on their lateral sides, the ribs 19 being located in the extensions of each other and being able to slide in the mounting slot.

[0067] like Figure 9 and Figure 10 As shown in detail, the locking element 29 can thus be snapped onto the connector lock 9 by means of a reusable snap-fit ​​connection. The snap-fit ​​30 is mounted on both sides of the locking element and hooks into the grooves 31 provided on the connector lock 9.

[0068] Locking element 29 provides additional strength to the corner and is primarily applied to, but not limited to, the corner above the operating crank. The snap-fit ​​connection and assembly of the corner locking member 29 is very simple, as described below: Figure 11 A to Figure 11 D illustrates the different stages of achieving the snap-fit ​​connection and locking the corners, thus... Figure 11 A and Figure 11 The stage shown in B occurs when window fitting 1 is first assembled onto the window slats; while Figure 11 C and Figure 11 D occurs when window fitting 1 is used during the first operation of operating mechanism 2.

[0069] Figure 11 A shows a corner transmission device with corner piece 8, wherein the connector lock 9, together with the locking member 29, has slid past the first leg 11 of corner piece 8 in the direction of the arrow, but has not yet engaged. At this stage, the spring assembly 14 is still locked by a temporary lock, in this case, the temporary lock being the release pin 17 as described above. It should be noted here that the locking member 29 is connected to the connector lock 9 by means of a snap-fit ​​30, which is provided on the locking member 29 for this purpose and hooks into a groove 31 applied to the connector lock 9.

[0070] exist Figure 11 In step B, the connector lock 9 slides further on the first leg 11 until it is above the connecting block 16 of the spring assembly 14. The connecting block 16 is now enclosed in the groove 23 provided in the connector lock 9, so that the spring assembly 14 is now non-sliply connected to the connector lock 9.

[0071] Upon further sliding, for example by rotating the operating mechanism 2, the release pin 17 disengages in the direction of the arrow on the connector lock 9, and thus the temporary lock is no longer locked. From here, the spring assembly 14 can slide along the connector lock 9 to which it is attached. Figure 11 C shows the connector lock 9 sliding upward to the locked position, whereby the locking member 29 at the end of the connector lock 9 is now fully driven into the corner. The locking member 29 is now engaged in place on the corner member 8 by means of a snap 32 provided on the locking member 29 for this purpose, and the snap 32 hooks into a snap member 33 applied to the corner member.

[0072] Therefore, the snap-fit ​​connection between corner piece 8 and locking piece 29 is more secure than the snap-fit ​​connection between locking piece 29 and connector lock 9.

[0073] When the operating mechanism 2 is rotated backward, the coupling lock 9 slides backward in the opposite direction (in other words, in the direction away from the corner), as... Figure 11As indicated by the arrow in D, the latch 30 disengages from the recess 31, causing the locking member 29 to disengage from the connector lock 9. The locking member 29 is thus held near the corner, where it performs its locking function.

[0074] Locking element 29 can also be installed on a conventional connector lock with a conventional connection.

[0075] Furthermore, the present invention is not limited to the rotating-tilting window accessory 1 with tilt-rotation function, but is equally applicable to windows that can only rotate or can only tilt.

[0076] The connection between the connecting block 16 and the spring assembly 14 can be achieved in various ways.

[0077] The end of the spring assembly 14 of the second leg 12 does not need to be connected to the movable leg 15 for connection with the sliding strip 3, but can instead be directly connected to the sliding strip 3.

[0078] According to such Figure 1 As shown in one particular aspect of the invention, the sliding strip 3 is applied to three areas: one area directly below the operating mechanism 2 and two areas above the operating mechanism 2.

[0079] The sliding strip 3, for example, is a component specified in Belgian patent application BE202105021, which is incorporated herein by reference in its entirety.

[0080] Figure 1 The sliding strip 3 shown in the figure does not necessarily have to be used with the corner drive and snap-fit ​​connection according to the invention, but can also be used in accessories of conventional corner drive devices that do not have snap-fit ​​connections.

[0081] The present invention is by no means limited to the embodiments described by way of example and shown in the accompanying drawings, but rather, without departing from the scope of the invention, the corner transmission device with snap-fit ​​connection according to the invention can be implemented in various forms and sizes.
