Description

Technical Field

[0001] This invention relates to a window hardware system, and more particularly to connecting tracks or rods of such a system.

[0002] This invention relates to a novel rod system, specifically a snap-fit ​​rod system. Background Technology

[0003] Window hardware systems comprise multiple functional components, such as locking mechanisms, fixed rails, corner actuators, and connecting rails. These connecting rails are also known as rods.

[0004] Typically, aluminum window systems feature hardware recesses in which rods are installed and slidable. The rods transfer movement of the hardware from one component to another. Locking points may also be provided on the rods.

[0005] A hardware recess is part of a window profile, which is typically standardized in windows. A hardware recess is a profile with an undercut recess that defines the space within which window hardware can be installed. Summary of the Invention

[0006] This invention relates to a rod intended for use in profiles with undercut grooves. The rod is fully integrated into the hardware groove.

[0007] Traditionally, the rod slides into the recess of the hardware. There are also systems in which the rod is snapped or tilted. Such systems are described in EP2754805B1, EP2607583B1, EP1707719, EP1867822 and EP3258044B1.

[0008] Because windows are made in a variety of sizes, the distances between the components to be connected to the rods also vary. Rod systems are known where the rods are of fixed length. Other rod systems (such as the applicant's known Chrono system) include several length variations, where the rod system compensates for distance variations.

[0009] The Chrono rod system comprises 11 modular composite tracks (also known as rods) of varying lengths, allowing for bridging of all window styles. The rods are equipped with connecting teeth for attachment to window hardware.

[0010] Distance variations are compensated for both by selecting rods of different lengths and by allowing for greater or lesser overlap between the rods themselves or between rods and components. The connection area (where greater or lesser overlap is possible) is called an adjusting connector. Other connections between different rods or between rods and hardware are called fixed connectors. Using these latter connectors, the ends of the rods are attached to the ends or bases of the connectors.

[0011] The Chrono system itself has many advantages, such as rapid assembly, no need for customization, and cutting tolerances adaptable by adjusting the connectors. However, a drawback of the system is its complexity. Installers must know in advance which members will be installed in the specific location. This depends not only on the window size but also on the selected configuration, such as the level of security and the installation options. Installers must consult construction drawings, catalogs, or software to understand which members must be used. Trained installers who only work with fixed configurations are familiar with the member selection criteria. Another drawback is that several rod dimensions must be set. EP1447505 describes a bracket. The bracket functions to connect the ends of two rods to a forked handle. The bracket can tilt and snap. This is achieved via a specific type of clamping element, where a specific height of rod is required to achieve sufficient suspension travel without plastic deformation of the clamping element for secure clamping. In the installed state, such a clamping bracket protrudes significantly from the window profile. A disadvantage is that such snap-fit ​​rods pose a potential theft risk because the bracket can detach from the outside. Furthermore, components such as locking points cannot be installed on the frame near the snap-fit ​​rods, as these would collide with the taller component. EP1867822 describes a snap-fit ​​or spring-shaped synthetic lip that forms a temporary (sliding) attachment in almost all components (except rods) that can be installed in a window slat. The disadvantage is that the snap-fit ​​is a separate, loose element. Furthermore, the snap-fit ​​and the component are made of two different materials: a zinc alloy and a synthetic material. Another disadvantage is that the snap-fit ​​is easily accessible for removing the component from the hardware recess, which could be done by an experienced thief. The snap-fit ​​is only temporarily secure. The final connection is made with another component (rod) that is mounted beneath other teeth with recesses and subsequently joined together by stamped screws. Therefore, the cooperating components cannot be loosely tilted.

[0012] The object of this invention is to provide a solution to at least one of the aforementioned and other disadvantages.

[0013] Therefore, the present invention relates to a connecting track or rod for engaging with an opening in window hardware, the U-shaped rod having a central longitudinal plane in cross-section and two legs or longitudinal sides on either side thereof, wherein the rod is provided with a clamping system for locking the rod into a hardware recess of a window profile, wherein the rod is further provided with connecting areas in the regions of the two ends of the rod for engaging the window hardware, the connecting track or rod being characterized in that at least one longitudinal side of the rod is provided with a plurality of lateral clamping elements or latches spaced apart from each other for clamping or latching the rod into the hardware recess, wherein the latches are arc-shaped, wherein the arc is elastically movable, wherein the end of the arc-shaped latch is connected to at least one longitudinal side, wherein the rod has a height or thickness such that the upper plane in the latched state in the hardware recess does not protrude significantly or only slightly from the hardware recess. In a preferred embodiment of the rod according to the invention, the portion of the rod that may protrude from the hardware recess in the snap-fit ​​state is beveled and / or rounded. In a preferred embodiment of the rod according to the invention, the ends of the arc-shaped fasteners are diagonally attached to the relevant longitudinal side.

[0014] In a preferred embodiment of the rod according to the invention, the arc-shaped fastener has a smaller cross-section in the curved surface compared to the attachment area.

[0015] The rod is a single-component system. The rod according to the invention consists of a single component. Additional elements are unnecessary, such as, for example, a cover plate.

[0016] Preferably, the fastener is provided along the full length of at least one longitudinal side.

[0017] Preferably, the gap between the two consecutive snap fasteners on the longitudinal side is the same.

[0018] Preferably, the lockable latch is an arc-shaped latch. The latch has an arc-shaped top view when viewed from above, wherein the arc is elastically movable, and the ends of the arc connect to a longitudinal side plane or longitudinal side. The latch is lockable into a hardware recess via the arc. The fasteners and rods are integrated together, meaning that the fasteners are attached to or connected to the rods and together form a single unit. The two longitudinal sides of the rod can be locked in the hardware groove, which, when viewed in cross-section, is located behind the two inwardly oriented legs or undercut longitudinal grooves.

[0019] When viewed in cross-section, the hardware recess has two inwardly oriented legs or undercut longitudinal grooves for receiving and / or locking the two longitudinal sides of the rod. The undercut longitudinal grooves form a recess under which the rod's latching element can hook for attaching the rod to the hardware recess. Based on the undercut of the longitudinal groove of the hardware part, the fastener and the lateral protruding arc form a clamping element.

[0020] The snap-fit ​​rod according to the invention is designed such that the clamping element (in the snap-fit ​​state) is completely enclosed within the hardware recess. In the snap-fit ​​state, the clamping element is inaccessible from the outside. Furthermore, the upper surface of the rod is preferably located in an extension of the upper surface of the hardware recess. Preferably, the height or thickness of the rod is not greater than the installation depth of the hardware recess.

[0021] The rod has a limited height such that, in the installed state, the upper surface of the rod does not protrude from the groove (more specifically, from the longitudinal groove of the hardware groove) or only slightly. The portion that may protrude from the hardware groove is beveled and / or rounded, making it impossible for a thief to grasp this portion to attempt to tamper with the rod. The limited height of the rod not only determines its burglarproof properties but also provides the possibility of positioning components (such as locking points on the frame) opposite the rod so that they do not collide with each other when the window is closed or the hardware is operated. Snap-on rods can also be used for windows with added burglarproof features, such as, for example, RC2 and RC3.

[0022] On the one hand, the space of the rod is limited by the height of the rod, which preferably does not protrude from the groove, or should only protrude slightly; but on the other hand, it is also limited by the width of the groove itself. This width (when viewed in cross-section) is defined by the fixed or adjusting connector, the two legs of the U-shaped cross-section of the rod, the overlap of the connection between the two legs, and the arc-shaped fastener. Compact snap-fit ​​fasteners are integrated into sufficiently robust and balanced components, where different parts and aspects achieve similar tensile strength. To resist sufficiently large tensile and compressive forces, it is recommended that the fixing and adjusting fasteners have minimal cross-sections. The overlap of the connection achieved through the toothed joint must be sufficiently large. It is also recommended that the U-shaped cross-section of the rods be sufficiently large, particularly the legs to which the toothed joints are attached. Needless to say, space is limited and laterally divided in the aforementioned aspects. Therefore, it is not obvious that sufficient suspension travel and strength are required to ensure that the rod in the installed state is firmly sealed and sufficiently away from the longitudinal groove below the hardware recess, while still remaining slidable.

[0023] The curved fastener is designed to provide sufficient suspension travel, which encloses the painted or anodized window profile in every case (i.e., with both minimum and maximum tolerances) and beneath an undercut longitudinal groove sufficiently away from the hardware recess. During fastening, the fastener may not break or plastically deform; however, the force required to fasten the connecting track must be acceptable. The first aspect of the design is that the arc in its cross-section gradually decreases towards the center of the arc. This has a dual effect. On the one hand, the thinner cross-section directly increases flexibility. On the other hand, there is an indirect effect: due to the thinner cross-section, the circulation when filling the mold with molten synthetic material is reduced, thus fewer or only shorter (glass) fibers enter the snap-fit, which is also beneficial to flexibility. In the attachment area, the snap-fit ​​has a larger cross-section, ensuring that the snap-fit ​​does not break when snapped together. Another aspect of the design is the diagonal attachment of the curved fasteners to the legs of the U-shaped cross-section. This ensures an optimal balance between strength and deformability of the fasteners within the available space. The higher the arc, the longer the arc. For example, snap-fit ​​connections are typically used, and snap-fit ​​components have a beveled inlet ( Figure 14 Therefore, when the rod is tilted or snapped into place, a force is generated that causes the snap-in to deform. Due to the sloping inlet, the deformation or suspension travel is initially limited. As the rod is pushed deeper into the groove, the contact point with the hardware groove moves further to the end of the sloping inlet. Therefore, the snap-in is pressed in deeper, and the suspension travel is greater at that point. The snap-in is designed such that, as the suspension travel increases, the length of the arc increases further into the inlet, providing more space for elastic deformation.

[0024] The attachment of the snap-fit ​​components is also optimized based on this principle. At the initial level of the inlet ( Figure 12 The suspension travel is still small, and the opening (where the fasteners do not include the legs with a U-shaped cross-section) is significantly shorter and higher (compared to the case where the suspension travel is larger).

[0025] diagonal attachment ( Figure 13This involves raising the ribs (which are horizontally disengaged from the upper side of the latch) diagonally, the ribs corresponding to the underside of the undercutting teeth of the groove in the installed state. These ribs run diagonally when viewed from the center of the latch towards the attachment of the latch. Therefore, the cross-section of the latch and attachment increases, and is strengthened in such a way that its rigidity is limited. Furthermore, the ribs deform freely inward in the leg direction of the U-shaped cross-section, but in other directions they rely on the undercutting teeth of the hardware groove in the installed state. Thus, the effect is that the ribs strengthen the latch only to a limited extent, yet the force required to release the lever is proportionally increased, which, together with strengthening the attachment, is clearly a desirable effect. As specified, the material cross-section is divided in a balanced manner for different components and aspects. Fiber-reinforced composite materials are necessary to achieve high strength in different components, preferably with a high percentage of fiber. However, the ratio between length and wall thickness is large, making it imperceptible to fill such rods with composite materials having a high fiber content. Furthermore, the geometry includes thin areas (such as snap-fit ​​elements), but preferably, the connecting teeth are also as fine as possible to achieve small step dimensions; these fine teeth must also extend the fibers for efficient operation. Therefore, the attachment of the connecting teeth is optimized on the one hand by their distribution on the legs and upper plane of the U-shaped cross-section, and on the other hand by applying the most suitable rounding. In fact, the shorter the minimum overlap required for a sufficiently tight connection, the smaller the achievable window style.

[0026] Therefore, the rod according to the invention provides a solution to the following challenges. By utilizing the arc-shaped locking element, sufficient suspension travel can be obtained for non-plastic deformation, where the locking rod protrudes only slightly from the groove. Therefore, the rod cannot be manipulated in the event of an attempted theft.

[0027] Integrating snap fasteners (also known as arc-shaped snap fasteners) into bars with such limited heights is not obvious, especially in combination with the U-shaped bar cross section and the lower connection, which has toothed joints on the inside facing downwards towards the legs. Combining the snap fastener (also known as the arc snap fastener) with the desired high tensile strength across the entire member is not obvious. To achieve the required high tensile strength and to limit stretching, a fiber-filled synthetic material is needed, preferably with a high fiber concentration. A stiffer material also hardens the fastener, which in turn requires a greater suspension travel (longer legs) or a narrower cross-section. Filling a thin cross-section with a synthetic material with a high fiber concentration is also not obvious. Preferably, the central portion of the curved surface or snap fastener (located between the connected ends) is free and not connected to the longitudinal side to ensure the required flexibility of the snap fastening system. Preferably, the fastener is made of an elastic material, such as a synthetic material, preferably a glass fiber-filled synthetic material. Preferably, the rod and the fastener are made of the same material.

[0028] Preferably, less glass fiber is supplied to the cavity of the snap fastener during mold filling to improve the elasticity of the snap fastener. In its simplest embodiment, the rod is partially or completely serrated along its length on one longitudinal side to be inclined below the first undercut longitudinal groove of the hardware recess; and a snap fastener is provided on the other longitudinal side to lock under the second undercut longitudinal groove of the hardware recess. Along one longitudinal side, the rod has teeth to tilt below the first leg or recess of the hardware recess. Another longitudinal side of the rod includes several latches for locking behind the second leg of the hardware recess. This occurs when the rod is tilted further into the hardware recess, where the arcuate latches are pushed into the recess. When the rod is tilted fully downwards to the bottom of the hardware recess, the latches are fully engaged and the arcuate latches release. The arcuate latches are now positioned below the hardware recess, with their upper sides pushing against the recess and keeping the rod locked within the hardware recess.

[0029] The cross-section of the rod or its dimensions are designed such that, in the functional position of the rod, the fastener abuts against the base of the longitudinal groove in the window profile. When the rod is pushed into the longitudinal groove and the size of the fastener is set accordingly (proportional to the undercut height of the longitudinal groove), the fastener can deform to a certain extent until the upper side of the fastener rests against the undercut. Due to the inherent restoring force of the elastic buckle, when the upper side of the buckle is supported on the base of the longitudinal groove, the upper side of the buckle pushes against the undercut, so that the rod is firmly clamped in the hardware groove with a limited gap and thus can slide without the large friction in the hardware groove.

[0030] Since the rods are the last items to be installed so that they can be visually selected, one end of them is attached to the fixed connector and the other end is attached to the adjusting connector of the window hardware. Therefore, and typically, the snap-fit ​​rods have a toothed portion on their bottom side or lower plane, which complements the toothed portion on the upward-facing side of the connector. The toothed portion is generally located on the side of the connector and on the inside of the rod. This toothed portion will engage to a sufficient depth.

[0031] Therefore, the connection area of ​​the rod includes a downward-facing toothed portion, which complements the upward-facing toothed portion of the window hardware connector.

[0032] The rod has a toothed portion on the bottom side of its longitudinal side. The tooth is a vertically protruding strip that is oriented perpendicularly to the intermediate longitudinal plane. The longitudinal side of the middle plane is provided on the inner or bottom side of two rows of parallel and spaced-apart teeth. The connecting area of ​​the rod is provided with two rows of teeth, which are located on the bottom side or internally on the two longitudinal sides and / or sides of the intermediate longitudinal plane.

[0033] The toothed joint is generally located on the inside of the connecting part of the rod, and on the side of the connecting part. Preferably, the central longitudinal plane of the rod is flat and rests within the plane of the hardware recess in the installed state. Preferably, the rod does not protrude or protrudes only slightly from the recess of the window profile, making it impossible for any thief to manipulate it. In this configuration, the connection areas at both ends of the lever are symmetrically arranged, allowing for tilting and locking on the left and right sides, above or below the locking element. Therefore, both ends can be connected to both fixed and adjustable connectors.

[0034] The orientation of the rod connection is independent of its position within the window and the hinges. There is a preferred tilt direction, depending on ease of installation or security. This symmetry allows the installer the freedom to always choose the same installation orientation.

[0035] In a preferred embodiment of the rod according to the invention, on the longitudinal side (i.e., the non-clamping side) having teeth, the toothed portion continues on the bottom side of the teeth, wherein the relevant toothed portion is provided with an inlet rounded or a smaller cross-section compared to the cross-section of the same teeth that continues to the intermediate longitudinal plane. By extending the toothed portion on the bottom side of the toothed part, the ends of the two connected toothed portions are aligned with the toothed portion of the snap-fit ​​rod. Preferably, one or both connection ends are executed with significant detail, such that the rods are connected via the connector in a clearly defined manner. For example, this detail could be thicker teeth in the fixed connector. By removing the corresponding teeth in the snap-fit ​​rod, the anti-misalignment connector is formed together with the fixed connector, and the snap-fit ​​rod still engages in each position on the adjusting connector.

[0036] In one particular embodiment, connection details are provided in the connection area of ​​the rod, and cooperation details are provided in one or both connection areas of the window hardware, such that the rod can be connected to the window hardware in a clearly defined manner and location.

[0037] In one specific embodiment of the rod according to the invention, one or two connection areas of the window hardware include widened teeth that complement widened spaces or openings in the connection areas of the rod.

[0038] The widened opening also includes the complete or partial removal of the tooth-like structures. By applying widened teeth to the fixed connector and providing complementary recesses at both ends of the snap-fit ​​rod, the effect is achieved that the rod cannot be mistakenly connected to the fixed connector and can be connected to the adjusting connector at each position. Preferably, the connection details of the fixed connector and the adjusting connector are different.

[0039] In a particular embodiment of the rod according to the invention, the rod (based on the space to be filled or based on the window size) is shortened to an appropriate length by, for example, cutting, and the rod is provided with connecting details at one or both ends by, for example, stamping.

[0040] In one particular embodiment, the full opening of the provided window hardware is not filled with snap-fit ​​rods; instead, through-connecting rods are first attached to the connection area of ​​a specific component. These through-connecting rods may have locking points or multiple option areas. This allows them to stand upright and be fixed in position, which in turn provides the advantage of positioning the component on the frame. Thus, the length bridging with the snap-fit ​​rods is relatively short. Therefore, the choice of rods remains very limited. Due to the option areas located on the through-connecting rods, configuration and options are also not considered.

[0041] According to another embodiment of the invention, the rod is disposed on two longitudinal sides of an intermediate longitudinal plane having a plurality of repeating or spaced fasteners, each of which is arc-shaped when viewed from above, wherein the arc is elastically movable. Preferably, the two longitudinal side fasteners are positioned opposite each other. The rod is a snap-fit ​​rod, which is customized during installation without sacrificing the snap-fit ​​capability. In the first embodiment, the rod is of a fixed length. Preferably, a plurality of different lengths are provided, and during installation, a rod of approximately the most suitable length is selected. The optimal length of the rod is determined by the available opening in the window hardware, which must be covered by the rod. The rod will overlap with a specific component at one end. This connection area (where more or less overlap is possible) is for adjusting the connection. At the other end and between the rods, a fixing connection is required. This fixing connection is directly connected in cross-section. At one end, the window hardware opening is provided with a fixed connector; and at the other end, an adjusting connector is provided. One end of the rod is fully connected at the level of the window hardware. The other end of the rod extends between the required minimum overlap and full overlap with the adjusting connector. The required minimum overlap is indicated on the adjusting connector. The connecting member is adjusted to have a sufficient maximum number of toothed joints, such that the connection with the rod connection area is possible by overlapping toothed joints, which are less than or equal to the maximum number of toothed joints.

[0042] In another embodiment, the rod is cut or sawn to the optimal length, wherein the cut is located between the two snap fasteners. In a preferred embodiment, the rod includes multiple cut or saw lines at various intervals, along which the rod can be safely cut or sawn. The cut or saw lines are located between two snap fasteners. The various intervals correspond to certain lengths of the rod. Preferably, the cut or saw lines are positioned between each snap fastener. In one specific embodiment, the cutting or sawing line is executed as a break line or break zone, along which the rod can be easily and quickly disconnected. This provides the advantage that no additional tools, such as saws or pliers, are required. The break line also provides a clean cut for disconnecting the rod.

[0043] The advantage of this invention is the snap-fit ​​rod, which can be easily sized on-site without sacrificing snap-fit ​​capability. In a preferred embodiment of the rod according to the invention, the rod in the connecting region is provided with one or more break lines or break regions, and the rod can be easily and quickly disconnected or cut along the break lines or break regions in a direction perpendicular to the longitudinal direction, wherein the break lines or break regions are located between two consecutive snap fasteners. Preferably, the fracture line or fracture region is formed as a groove, or a complete or partial reduction of the cross-section of the intermediate longitudinal plane and / or longitudinal sides.

[0044] The rod can be neatly broken, cut, or sawed off along the fracture line or fracture area. Preferably, the fracture line or fracture area is provided with a V-shaped groove to promote tear initiation. At one or both ends of the break line, a V-shaped notch is provided on the horizontal side of the longitudinal side of the member.

[0045] The break line or break region defines one or more segments in the longitudinal direction of the member, wherein each segment is provided with at least one snap-fit ​​element on at least one longitudinal side and is provided with a connection area.

[0046] Cut or saw lines and break lines define segments of the rod. Preferably, each segment is provided with at least one fully snap-fit ​​element. Therefore, the rod comprises several segments.

[0047] Preferably, a segment of the same member is identical, wherein the break line or break region is located at a fixed distance from each other.

[0048] In an alternative embodiment, one segment of the same member is smaller or larger than others, wherein the break line or break region is located at a variable distance from each other.

[0049] The advantages of this invention include intuitive and rapid component selection, a fast learning curve, greater flexibility, and the possibility of employing lower-skilled personnel.

[0050] The purpose of this invention is to provide a significantly simplified selection of rods for window hardware. The condition for intuitive selection and display of rods is that the rods can still be snapped into the hardware grooves later without having to remove or disassemble the pre-installed parts again. For bridging the variable distance between two components of window hardware, one with a fixed coupling (e.g., a corner actuator) and the other with an adjusting coupling (e.g., a locking element), a later-installable (non-sliding) rod can be used, allowing the desired length to be visually measured between the two components. The correct length can be selected by displaying the rod in front of the opening to be bridged.

[0051] The rods according to the invention can be used in different ways.

[0052] In the first approach, the optimal rod length is used, which is the optimal number of fixed-length rods, for example, four rods of 126-206-286-366mm. One end of the rod is fully connected at the level of the fixed connector of the window hardware. The other end of the rod extends between the required minimum overlap and full overlap with the adjusting connector. The required minimum overlap is indicated on the adjusting connector. The second way to choose the appropriate rod length is to position the rod in front of the relevant opening of the window hardware and shorten it as precisely as possible (cut or saw it off). In this case, the adjusting connector is just longer than the fixed connector and is only used to compensate for any cutting errors. In this case, there is no need to distinguish between the adjusting connector and the fixed connector. They can be equivalent.

[0053] In the third option, the rod is broken or cut to a certain size using pre-set breakable or cuttable segments. The rod is positioned in front of the opening to be filled, with one end corresponding to the start of the fixed connector. Subsequently, the rod is broken or cut along the break or cut area, which falls between the minimum and maximum connection lengths. Therefore, the required length is greater than the opening of the window hardware to be filled, and other variations (approximately one segment) are compensated for by adjusting the connector.

[0054] For this purpose, the member is divided into segments. Each segment has at least one snap-fit ​​element on at least one longitudinal side.

[0055] Preferably, these segments are identical. In another embodiment, some segments are smaller or larger than others. Segments may be smaller, for example, for bars of smaller required length.

[0056] Therefore, each segment includes a section with connecting teeth, which preferably, but not necessarily, completely correspond to the connecting teeth of the fixed connector. Break or cut areas are provided between the segments.

[0057] Each segment must have the necessary connecting teeth to allow it to still connect after breakage or cutting.

[0058] The fracture or cutting area is a region with a reduced cross-section, and preferably has V-shaped grooves along different sides to promote tear initiation. On the one hand, the members must resist large tensile or compressive loads; on the other hand, they are locally weakened to allow for breakage. This contradiction is resolved by utilizing fiber-reinforced strips, such as, for example, UD strips. For this purpose, the bar is provided with fiber-reinforced strips, preferably applied along the entire length of the bar or at least at the level of the break line or break region. In a preferred embodiment of the rod according to the invention, the fiber-reinforced strip is applied to the bottom side or lower plane of the intermediate longitudinal plane along the full length of the rod, or at least to the level of the break line.

[0059] The strip can also be applied to the upper side of the intermediate longitudinal plane, or applied in a U-shape depending on the cross-section of the rod.

[0060] Fiber-reinforced strips consist of continuous fibers, such as glass, carbon, or aramid bonded to a polymer resin.

[0061] These fiber-reinforced strips are polyamide-based tapes, or other polymer resins, which are arranged along their entire length together with carbon or glass fibers or other reinforcing fibers. In this way, the rod is reinforced with continuous fibers (glass, carbon, aramid, flax, etc.) that continue along the bending length of the rod (from segment to segment, through the fracture zone). The continuous fibers in the UD tape transfer forces from segment to segment; however, the reduced cross-section of the fracture zone allows the rod to break between two segments. The present invention also relates to a method for engaging and locking a rod as described above into a hardware recess of a window profile, the method comprising the steps of: a) selecting a suitable rod according to the size of an available opening in the window hardware, wherein the rod is present in front of the opening to be filled, and one end of the rod corresponds to the base of a fixing member; b) engaging and tilting a tooth on one longitudinal side of the rod into a first longitudinal recess of the window profile, wherein one end of the rod abuts against a component of the window hardware at the level of the fixing member of the window hardware; c) further tilting and snapping a latch on the other longitudinal side of the rod downward to the bottom of a second longitudinal recess of the window profile, wherein the other end of the rod is engaged between minimum and maximum overlap at the level of the adjusting member of the window hardware.

[0062] In the first embodiment, in step a), a fixed-length rod is used, or the rod is sawn or cut to a certain dimension between two consecutive snap fasteners.

[0063] In the second embodiment, the rod is broken or cut to a suitable size at the break line or break region, the suitable size falling between the minimum and maximum connection length, wherein the rod is disposed at both ends having suitable connecting teeth in step a).

[0064] Steps b) and c) also apply to snap fasteners attached to a member having snap fasteners on two longitudinal sides. Attached Figure Description

[0068] The spaces 6 between the fasteners 5 are identical. These fasteners 5 are identical and are applied along the entire length of the rod 1.

[0069] The other longitudinal side 3 of the rod 1 is provided with a tooth 7, which extends along the entire length of the rod 1. The tooth 7 protrudes from the side of the rod and engages in the groove of the hardware recess.

[0070] For a specific size range of window hardware, this is an example of a fixed-length rod. For this purpose, the end of the rod 1 is provided with a connecting toothed portion 8 on the bottom side B. Along a specific length from the end of the rod, the connecting toothed portion 8 includes two rows of protruding teeth 9, which are generally located on the side flanks of the longitudinal side, adjacent to the bottom side B of the intermediate longitudinal plane, continuing at the free end of the longitudinal side, and oriented perpendicular to the longitudinal direction of the rod. The tooth-like part 7 is provided on its bottom side, which has vertical reinforcements or protrusions 10, 11 spaced at regular intervals.

[0071] Figure 2 A rod 1 is shown, wherein a connecting toothed portion 8 is provided along the entire length of the rod 1. To achieve a minimal window style, it is desirable to even shorten the fixed-length rod by, for example, sawing it off. In this case, the toothed portion 8 and the teeth 9 are necessary along the entire length, because the sawn-off end of the rod must be provided with a connecting toothed portion.

[0072] Figure 2 The rods have the same properties as the rods in Figure 1, except that the toothed joints are not only provided at the ends of the rods, but also along the entire length of the rods. Figure 3A and Figure 3B The details of rod 1 in Figure 1 are shown, viewed from above ( Figure 3A ) and viewed from below ( Figure 3B ). It can be clearly seen here that the curved surface 14 of the arc-shaped fastener 5 is not fastened to the rod and is used for maximum flexibility when fastened. The arc-shaped end 13 is attached to the longitudinal side of the rod.

[0073] Figures 4A to 4C The present invention shows a cross-section of the rod 1, which is snapped into two undercut longitudinal grooves 16, 17 of the hardware groove 15. The hardware recess 15 is part of the window profile 23, which is typically standardized in windows. The hardware recess is a profile 23 with undercut recesses 16, 17 that define the recess 15 in which hardware can be installed. The latching element 5 is thus latched below the longitudinal groove 16, and the toothed element 7 is latched below the longitudinal groove 17. The form of the latching sections of the latching element 5 and the toothed element 7 is such that the two sections at the top and bottom almost contact the upper and lower sides of the longitudinal groove. This achieves a secure lock. A minimum clearance exists to accommodate tolerances and allow for displacement.

[0074] Figure 4A It shows Figure 4B and Figure 4C The transverse section of member 1. Figure 4B The horizontal cross-section of the curved surface of the buckle 5. Figure 4C The horizontal cross-section of the space between the two snap fasteners 5.

[0075] Figures 5A-5B An embodiment of the connecting rail or rod 1 is shown according to the present invention. Figure 5A A top view of rod 1 is shown. Figure 5B The bottom view of member 1 is shown. Member 1 has the same as Figure 2 The rod has the same properties as the other rod, wherein the connecting toothed portion 8 is provided on the bottom side of two longitudinal sides along the entire length of the rod. In this case, the connecting toothed portion 8 is necessary along the full length of the rod because the rod can break into segments 18.

[0076] These segments 18 are defined by a break line or break region 19 at the level of the gap 6 between two consecutive snap fasteners 5. The rod 1 can be neatly broken via the break line or break region 19, thereby shortening its length. The precise location of the break line or break region 19 ensures that the snap fastener 5 remains intact at all times. Therefore, the member can be shortened according to the length of one or more segments.

[0077] The fracture line or fracture region 19 is set as a V-shaped groove (perpendicular to the longitudinal direction) on the upper side A of the rod in the intermediate longitudinal plane, and continues on the two longitudinal sides. At the level of the fracture line or fracture region 19, the toothed part 7 is provided with a V-shaped recess 20. At the level of the V-shaped recess 20, the connecting toothed part 8 is not provided, or the connecting toothed part is interrupted.

[0078] Figure 6 The cross-section of the rod 1 is shown. The rod 1 is provided with a UD strip 21 on the bottom side B of the intermediate longitudinal plane 2 or on the lower plane of the rod.

[0079] Figures 7A-7F The diagram shows a usable opening 22 into which the rod 1 according to the invention is snapped into and locked into a hardware recess 15. The usable opening is defined at two ends by two components 32, 33, which are pre-installed in the hardware recess.

[0080] like Figure 7A As shown, the opening 22 of the hardware groove is located at one end with a fixed connector 24 and at the other end with an adjusting connector 25. The fixed connector 24 is positioned adjacent to the locking point 31.

[0081] The rod 1 is positioned with one end 27 abutting against the component 32, which has a locking point 31. Using the other end 28, the rod measures sufficient overlap between the minimum and maximum available distances from the adjusting connector. For example, sufficient overlap is achieved with an engagement of 19 mm or 9 teeth. according to Figure 7B The rod 1 is locked in the hardware recess 15 by first placing the toothed part 7 in the first longitudinal recess. This is shown in cross-section. Figure 7D middle.

[0082] Subsequently, the latching member 5 latches onto the lower part of the second longitudinal groove 16, as also shown in cross-section. Figure 7E middle. The locked state of the rod 1 in the hardware groove 15 is shown in Figure 7C middle. In the longitudinal cross-section of the longitudinal side portions 3 and 4, Figure 7F The diagram shows the connecting teeth 8 at both ends of the rod finally locking into the fixed connector 24 and the adjusting connector 25 of the window hardware.

[0083] Figures 8A-8B The longitudinal section of the rod 1, locked to the connector, is shown, wherein the locking mechanism includes a mis-insertion prevention connector for incorrect installation. This means that the rod 1 can only be attached to the (fixed) connector 24 of the window hardware in one manner.

[0084] For this purpose, the fixing member 24 is provided on two longitudinal sides by teeth 26, which are wider than any other teeth 29 of the fixing member. The wide teeth 26 are positioned on the ends of the fixing member 24.

[0085] Complementing this, the connecting toothed portion 8 of the rod is after the last tooth 9 (in the case of a connecting toothed portion of limited length). Figure 8A Or between two teeth 9 (in the case of a connecting tooth joint on the larger or entire length of the rod) Figure 8B A wider space 12 is provided. This wider space 12 is applied at a specific distance, which corresponds to the distance from the wide tooth 26 of the fixed connector 24 to the base 30 of the connector. This distance ensures that the end 27 of the rod rests against the base 30 of the fixed connector 24 during installation.

[0086] As in Figure 2 It can also be seen that the two opposing teeth 9 of the connecting toothed part 8 are removed at a specific distance from the end of the rod, so that a wider space 12 is formed between the two teeth 9. Therefore, the rods will always be correctly installed and locked in their specific positions on the window hardware, and incorrect installation is avoided. Figure 9 The rod 1 is shown, wherein on the side having teeth 7 (i.e., the non-clamping side), a toothed portion 8 continues on a longitudinal side or the bottom side 34 of the teeth 7. The associated toothed portion 8 is provided on the bottom side 34 of the longitudinal side, which has a smaller cross-section or thickness 35 compared to the cross-section or thickness 36 of the same teeth, which also extends to the intermediate longitudinal plane. The inlet rounding (smaller cross-section or thickness) 35 is configured in cooperation with the toothed portion of the connector for an automatic search function of the toothed portion of the rod. The connector may also be provided with a top rounding. Once tilted, the toothed portion 8 on the bottom side 34 no longer contacts the connector and is no longer functional. The toothed portion section on the longitudinal side (not located on the bottom side) is not provided with an inlet rounding 35, which is used for maximum overlap and strong connection.

[0087] The purpose of this is to facilitate the searching of the toothed joint. It is envisioned that if the length difference between the two connectors does not correspond to an integer number of teeth, then one of the two connectors must be slightly displaced. The component is also made to allow for this slight displacement. In the worst case, a situation may occur where the teeth are necessary for the toothed connector. To ensure a smooth process, the toothed joint continues on the bottom side of the longitudinal side provided with the teeth 7. Figure 10 A front view of the locking member 5 is shown, which is connected to the longitudinal side 4 of the rod 1 by diagonal attachments 37. The diagonal attachments ensure maximum resistance to release.

[0088] Figure 11 A top view of the rod 1 and the fastener 5 is shown, with the fastener 5 shown in different cross-sections in the following figures. Figures 12 to 17 Cross sections XII to XVII are shown respectively.

[0089] The opening 40 below the arc of the snap fastener is smaller at the bottom than at the top to avoid weak areas of tensile load near the beveled edge / notch between segments. Figure 17 A cross-section of the longitudinal side 3 of the toothed joint is shown, wherein the beveled edge 39 is provided for reinforcing the convex connector. The arc-shaped fastener 5 is provided with a cavity near the attachment, which ensures additional flexibility.

[0090] This invention is by no means limited to the embodiments described as examples and shown in the accompanying drawings, but the connection tracks of the invention as defined in the claims may be implemented in various variations without departing from the scope of the invention.
