Description

[0001] manual This invention relates to a latch plate for a transmission rod hardware component for sliding windows, sliding doors, and similar devices. The latch plate includes a base and a U-shaped bridging member. The base is disposed on the tongue and groove surface of the mullion of the frame of the sliding window or sliding door, and the bridging member is disposed on the base. The bridging member and the base have corresponding contact surfaces and are detachably connected to each other. The bridging member has a locking groove.

[0002] A similar snap plate is known from EP 3 760 818 A1. This snap plate has a base and a bridging element. The bridging element is constructed such that it has two locking slots, one on the lower side and one on the upper side, and configured in opposite directions. One locking slot is designed for a right-side stop, and the other for a left-side stop. Therefore, the snap plate can be mounted on both sides by simply rotating the bridging element. The bridging element has notches on both sides that engage with the snap hooks of the base. These snap hooks are only located on the upper side of the base.

[0003] A multi-segment snap plate is also known from DE 299 0318 2 U1. The snap plate shown has three parts in total, consisting of two metal components (forming a base plate and a cover plate) and an end plug (forming the side end of the snap plate). During pre-assembly, the base plate and cover plate can be loosely connected together because one side of the base plate has a pin, and the other side of the cover plate has a corresponding pin inlet. After pre-assembly, the two snap plate components must be welded together.

[0004] The purpose of this invention is to further improve the above-mentioned latch plate, making it easy to install and ensuring its robust functionality.

[0005] According to the invention, this objective is achieved by arranging the locking groove of the bridging member in the main web plate connecting two opposing arms, wherein the main web plate is arranged to be spaced apart from the tongue and groove surface and parallel to the support surface located at the base, and the locking groove has an inlet region and a control curve, wherein the control curve branches out from the inlet region, and the control curve and the inlet region are each arranged close to one of the two opposing arms of the bridging member.

[0006] With this design, the bridging member utilizes its two arms to clamp the base from both sides, thus ensuring easy assembly and particularly stable fixation in a simple manner. Compared to the arms, the large width of the main web provides sufficient space for the locking groove, which can thus have a large entry area for the bolt on the fan side to be inserted, and the bolt on the fan side can be controlled by the curve to allow the fan to be sufficiently close to or away from the frame.

[0007] According to an advantageous improvement of the invention, the functional security of the strike plate is improved, wherein the entry area is implemented as generally rectangular and extends into a support arm, wherein the continuity of the support arm in its length is maintained, and the entry area has an extension limited by a protrusion in the direction of a control curve. Therefore, the entry area of ​​the lock slot has the largest possible size. That is, even if the bolt is not in the ideal entry position, it can move into and out of the strike plate. Therefore, even in this case, the sliding window can be opened and closed. The continuity of the support arm maintains a high degree of stability of the strike plate.

[0008] As the control curve narrows from the entrance area and extends at an angle inclined relative to the longitudinal extension of the bridging member in the direction of the support arm, until the screw axis forms the central axis of the control curve and the parallel sidewalls of the end area of ​​the control curve extend along this central axis, the strike plate provides particularly simple functionality, especially capable of withstanding high loads via the bolt. By arranging the central axis of the end area on the screw axis (which can be formed by two helical connectors connecting the strike plate to the frame), the bolt is fixed on this screw axis when in the locked position. Thus, the possible leverage force is kept at a very low level when such forces occur, which are applied to the strike plate by the bolt in the opening and closing directions of the sliding window and therefore parallel to the bolt axis. As a result, the strike plate exhibits particularly strong resistance to deformation. Such loads occur, for example, when attempting to illegally force the sliding sash to the open position. The wide transition section from the entrance area of ​​the control curve makes safe bolt entry possible.

[0009] According to an improved version of the snap plate of the invention, the guidance of the snap plate in the control curve is particularly advantageous and the operating force is particularly uniform when the control curve has a guide edge extending from the entrance region (for guiding the control bolt guided within the snap plate), and this guide edge transitions from a substantially straight edge inclined towards the entrance region to an arc segment, and this arc segment forms a transition between the straight edge and one edge of the end region, wherein the arc segment is at least equal to the distance between the one edge of the end region and the support arm. This form of control curve ensures that the push-pull fan body fits evenly against the frame and keeps the force required to be applied by the operating handle at a very low level. A smooth transition is ensured by the large arc segment between the straight edge and one edge of the end region.

[0010] Furthermore, the tool-free connection between the bridging component and the base can be improved by having notches on both sides of the base, which are arranged opposite to the protrusions of the bridging component. Therefore, once the bridging component and the base are joined together, the protrusions of the bridging component engage with the notches located on the base. This forms a form fit that secures the bridging component and the base together. This makes particularly easy pre-assembly of the two components possible.

[0011] Furthermore, this simplifies the assembly of the bridging component on the substrate, as lugs are arranged on one side of the substrate, supporting one arm of the bridging component. These lugs provide support during the initial connection between the substrate and the bridging component via the raised sections. Therefore, one arm of the bridging component is first positioned at the lug, and a second arm is pressed against the opposite side of the substrate. This arrangement prevents the first arm from slipping out while simultaneously securing the second arm.

[0012] If the strike plate has a damper, it facilitates easy operation of the sliding hardware. Therefore, the window sash does not directly impact the rigid material forming the bridging element, but instead rests against the damper, which is typically made of a soft material, such as rubber. This impact damping also reduces the mechanical load on the strike plate, such as loads caused by vibration. This helps extend the lifespan of the strike plate.

[0013] When the stop damper is positioned on the base, the force transmission through the stop is designed to be particularly advantageous. Therefore, when the fan closes, the force is primarily transmitted through the base, and from there to the frame. This enhances the damping effect.

[0014] If the bridging element has a notch in which a stop buffer is arranged, the snap plate can be constructed to be particularly compact. This design allows the stop buffer to be mounted directly on the surface area of ​​the bridging element. Therefore, the snap plate does not need an additional area specifically for mounting the stop buffer.

[0015] If the stop damper has a mushroom shape with a head and ribs, the force that occurs at the stop damper when the fan closes can be better dispersed. The head of the damper extends out of a notch in the bridging member. Therefore, when the fan closes, the underside of the head presses against the bridging member, and part of the force is also transmitted through the bridging member. This reduces the peak load acting on a single component.

[0016] Furthermore, this improves the stability of the stop buffer by providing a funnel-shaped extension that is at a distance from the lower edge of the head, where such distance is at least equal to the material thickness of the bridging member. Therefore, the rib has a diameter that varies depending on the height. Moreover, this distance, at least equal to the material thickness of the bridging member, creates a form fit between the stop buffer and the bridging member.

[0017] In another design according to the invention, if the stop buffer is arranged on a cantilever of the base, the assembly of the stop buffer is particularly simple. The cantilever is arranged on one side of the base and does not overlap with the bridging element. Thus, only the connection between the stop buffer and the base plate needs to be established.

[0018] This invention permits many embodiments, some of which are exemplarily illustrated in the accompanying drawings. Figure 1 A sliding window with a sliding fan body and multiple locking plates according to the invention is shown; Figure 2 A latching plate according to the invention is shown installed at the frame of a sliding window; Figure 3 A perspective view showing the latch plate according to the invention installed on the frame of the sliding window and some of the sash-side hardware components; Figure 4 Show along Figure 2 A cross-sectional view of the frame with the locking plate according to the invention along line IV-IV; Figure 5 A top view shows a first embodiment of the latch plate according to the invention when the bolt is in the locked position; Figure 6 Show Figure 5 The back view of the latch plate shown; Figure 7 Show Figure 5 and Figure 6 Exploded perspective view of the latch plate; Figure 8 It shows the passage along line VIII-VIII Figure 5 A cross-sectional view of the strike plate; Figure 9 The stop buffer is shown at the latch plate; Figure 10 This illustrates an extended embodiment of the latching plate according to the invention shown in the previous figure; Figure 11 Another embodiment of the locking plate according to the invention is shown.

[0019] exist Figure 1 The diagram shows a sliding window in the sliding position, having a sliding sash 2 that can be opened from a frame 1 and slide relative to the frame. In this position, the sliding sash 2 is opened from the frame 1 and can therefore slide relative to the frame. Furthermore, a non-sliding second sash 3 is arranged within the frame 1. In other embodiments, the second sash 3 may also be slidable. Carriers 5 and 6 are arranged below the sliding sash 2, sliding in a rail, and two slidably guided ramps 7 and 8 are arranged above the sliding sash. A drive rod hardware 9 is schematically shown, having an operable handle 10. By manipulating the handle, a longitudinally sliding drive rod 11 is driven. This moves a locking bolt 37 arranged on the drive rod 11. Figure 1 (Not shown in the image), these bolts lock the sliding window. For this purpose, bolt 37 engages with a strike plate 12 located on the frame side at the mullion 44, in... Figure 1 The diagram illustrates three of the latch plates.

[0020] exist Figure 2 The image shows the arrangement of the latch plate 12 according to the invention at the vertical member 44 of the frame 1. The latch plate 12 is arranged on the tongue and groove surface 42 within the tongue and groove space of the sliding window. The multi-segment structure of the latch plate 12, consisting of a bridging member 13 and a base 14, can be seen in this view. In this view, the base 14 forms the upper and lower ends of the latch plate 12. Furthermore, a locking groove 17 is also visible, which accommodates the bolt 37 of the transmission rod hardware 9 when the sliding window 2 is closed. The bridging member 13 has two arms 30 and 31, of which arm 31 is visible in this figure. Recesses 22 are further formed at arm 31, these recesses opposing the protrusions 19 on the inner side of arms 30 and 31 shown in later figures. A stop buffer 16 is arranged at the latch plate 12 in the direction of the sliding window 2 (not shown). This stop buffer is made of a rubber elastic material and acts as a terminal stop when the sliding window 2 is closed. This reduces the mechanical load borne by the rigid hardware components of the push-pull hardware.

[0021] Figure 3 The perspective view shows the latch plate 12 according to the invention, arranged together with several fan-side hardware components in the frame 1 in the installed state. A stop buffer 16, arranged on the latch plate, is opposite to the fan-side hardware components and acts as a stop for the closing movement of the push-pull fan 2. The illustrated fan-side hardware components include a drive rod 11, a cover rail 45, and a bolt 37. The cover rail 45 serves as a panel for the drive rod 11 arranged below it, thus protecting it from dust, external mechanical loads, and human damage. The bolt 37 is arranged on the drive rod 11, so that it slides as the drive rod 11 slides. For this purpose, the bolt 37 passes through an elongated hole in the cover rail 45. The locking groove 17 of the latch plate 12 is also shown in the figure. When the push-pull fan is closed, the bolt 37 enters this locking groove. The illustrated hardware component positions correspond to an intermediate position between the unlocked and locked states of the push-pull fan 2.

[0022] Figure 4 A horizontal cross-section of the vertical strut 44 passing through the frame 1 along line IV-IV is shown. This cross-section shows the latch plate 12 mounted on the frame 1, and the hardware components arranged opposite it on the fan side of the push-pull fan body 2. In this figure, it can be seen how the bolt 37 is arranged at the drive rod 11 and how it passes through the cover rail 45 to interact with the latch plate 12. The latch plate is arranged on the tongue-and-groove surface 42 of the frame 1.

[0023] Figure 5A top view of the latch plate 12 is shown. The latch plate 12 consists of two parts: a bridging member 13 and a base 14. The main web 34 and two support arms 30, 31 constitute the bridging member 13, which has a locking groove 17 with an opening 18, an inlet area 32, and an extension 46. When the push-pull fan body 2 is closed, the bolt 37 enters the generally rectangular inlet area 32 of the locking groove 17 and then moves to the locked position along the control curve 33. The locking groove 17 has an opening 18 at the support arm 30 of the bridging member 13 and an extension 46 on the side opposite the opening 18. The extension 46 is limited by a protrusion 47 located at the transition point to the control curve 33. The locking groove 17 is further enlarged by the opening 18 and the extension 46. With the enlargement of the locking groove 17, the bolt 37 has a large inlet area. Therefore, even if the bolt 37 is not in the optimal position, for example, due to high external pressure on the push-pull fan 2, the push-pull fan 2 can be closed smoothly. After the bolt 37 is pushed into the locking groove 17 by closing the push-pull fan 2, the bolt is guided along the control curve 33 by manipulating the handle 10 and subsequently moving the transmission rod 11. The control curve 33 has several sections, the first of which is formed by a straight edge 38. By guiding along this edge, the bolt, and thus the push-pull fan 2, is pulled closer to the frame 1. The next section is formed by an arc segment 39. Through the large arc segment 39, the bolt 37 is forced to move slowly and smoothly parallel to the arms 30, 31. Therefore, the stroke of the push-pull fan 2 displacement becomes smaller and smaller. In other words, this stroke now serves to place the bolt 37 in the most secure locked position possible. This locked position is located within the end region 40 of the control curve 33, which is mainly limited by the edge 41. When the drive rod hardware 9 is in the position shown in the figure, the bolt 37 is located within the end region 40 of the control curve 33, thus the sliding sash 2 is in its locked state, in which the sliding sash 2 is tightly sealed to the frame 1. The bridging element 13 and the base 14 can be connected to each other, for example by screws, through holes 15, and are screwed to the frame 1. The connecting line 35 connecting these holes 15 forms the central axis of the end region 40 of the control curve 33. With this design, the latch plate 12 can withstand particularly high tensile forces introduced via the bolt 37 in the locked state. Such forces can occur, for example, during an attempt to break in. The latch plate 12 also has a stop buffer 16. This stop buffer is arranged on the base element 14 and extends through the notch 24 in the bridging element 13. The stop buffer 16 is preferably made of a rubber elastic material, designed to ensure a gentle end stop when the sliding sash 2 is closed. This ensures that the sliding window is easy to operate and durable.

[0024] Figure 6 Show Figure 1The image shows a rear view of the latch plate 12. In this view, it can be seen that the bridging member 13 is U-shaped, with its two arms 30, 31 surrounding the base 14 from opposite sides. In the illustrated embodiment, the bridging member 13 has two protrusions 19 at each of its two arms 30, 31. These protrusions 19 allow for a reliable force fit between the base 14 and the bridging member 13. As shown in this embodiment, the connection can be improved by designing a notch 20 at each of the protrusions 19, located at the base 14. Thus, even without screw connections, a form fit exists between the bridging member 13 and the base 14 in the assembled state. Furthermore, the base has lugs 21 on one side for assembly assistance. Therefore, when assembling the bridging member 13 and the base 14, the first arm 31 can be guided first via the side of the base 14 and supported by the lugs 21. Subsequently, the second arm 30 can be guided via the second side of the base 14. During this process, the first arm 31 can no longer slip due to the presence of lug 21.

[0025] exist Figure 7 The exploded view of the latch plate 12 according to the invention is shown in the perspective view. For clarity, the stop buffer 16 is not shown. The U-shaped cross-section of the bridging member 13 and its two arms 30, 31 are clearly visible in this view. An inwardly pointing bulge 19 is formed in the bridging member, for example by stamping, and the bridging member is preferably made of a deformation-resistant material such as steel. This process leaves a recess 22 on the outer side of the bridging member. Furthermore, holes 23 in the base 14 are also visible in this view; in the assembled state, these holes are arranged below the holes 15 in the bridging member 13. These holes are designed to be continuous, so that the screws connecting the bridging member 13 and the base 14 can also be used to secure the latch plate 12 to the frame. The bridging member has a notch 24 for receiving the stop buffer 16.

[0026] Figure 8 The latch plate shown in the previous figure is along Figure 1 The cross-sectional view along line VIII-VIII is shown in the figure. The U-shaped cross-section of the bridging member 13 and how it surrounds the sides of the base 14 via its arms 30, 31 are also clearly visible. Even the bulge 19 and its associated recess 22 are clearly visible. Furthermore, the design of the notch 20 is shown. The bulge 19 is formed by an undercut through the edge 24 arranged on the side of the base 14. During assembly, the bulge 19 is first guided along the outer side of the edge 24. In this case, the spring force of the material presses the arms 30, 31 of the bridging member outward. Once the bulge 19 crosses the edge 24, the spring force pushes the arms 30, 31 inward, and the bulge 19 engages in the notch 20. The locking plate 12 can then be positioned at the desired location on the frame 1 and connected to the frame 1 via screws through holes 15, 23.

[0027] Figure 9The stop buffer 16 according to the invention is shown in detail. The stop buffer 16 preferably has a mushroom shape, consisting of a head 25 and ribs 16, and is made of a rubber-elastic material. This shape allows the stop buffer 16 to be easily arranged in a corresponding receiving portion at the base 14, while providing a large stopping surface. The stop buffer also has a funnel-shaped extension 27 arranged at a defined distance d from the underside of the head 25. The bottom of the funnel-shaped extension 27 faces the head 25. The distance d is chosen such that it corresponds at least to the material thickness of the bridging member 13. With the arrangement of the funnel-shaped extension 27, wherein the bottom of the extension has the aforementioned orientation and the extension has the defined distance, the stop buffer can be effortlessly mounted at the locking plate 12, even after the bridging member 13 and the base 14 are assembled. For this purpose, the stop buffer 16 is simply pressed over the notch 24 of the bridging member 13. Preferably, the difference between the distance d and the material thickness of the bridging member 13 is slightly greater than the manufacturing tolerance. Therefore, the stop buffer 16 is securely held at the bridge 13.

[0028] Figure 10 An extended embodiment of the snap plate 12 in the previous figure is shown. The snap plate 12 additionally has a rib 28 located at the base 14. The rib 28 serves for further stabilization and force transmission of the snap plate 12. Preferably, the rib 28 is arranged on the side of the base 14, where an opening 18 for the lock groove 17 is provided. This side of the snap plate 12 typically faces the person operating the hardware and can be seen when opened. In this case, the rib 28 additionally functions as a panel, improving the appearance of the snap plate 12.

[0029] exist Figure 11 Another embodiment of the latching plate 112 according to the invention is shown. In this variant, the latching plate 112 still has a bridging member 113 and a base 114. Furthermore, a cantilever 129 is arranged at the base, which does not overlap with the bridging member 113. In this embodiment, a stop buffer 116 is arranged at the cantilever 129. With this design, the stop buffer 129 is particularly easy to assemble because it does not need to additionally pass through the groove of the bridging member 113, in addition to being arranged on the base 114. Therefore, the milling process for the receiving portion of the stop buffer 116 is no longer required when manufacturing the bridging member 113.
