Description

[0001] The invention relates to a striking plate for a drive rod fitting of a sliding window, a sliding door or the like, wherein the striking plate comprises a base body and a U-shaped bridge, wherein the base body can be arranged on a rebate surface of a vertical beam of a frame of the sliding window or sliding door and the bridge is arranged on the base body, wherein the bridge and base body have corresponding contact surfaces and are detachably connected to one another and the bridge has a locking recess.

[0002] A similar striking plate is known from EP 3 760 818 A1. The striking plate comprises a base body and a bridge. The bridge is designed to have two locking recesses, each arranged on a bottom and top side, and designed in exactly opposite directions. One locking recess is designed for a right-hand stop, the other for a left-hand stop of the striking plate. Thus, the striking plate can be used on either side by simply rotating the bridge for installation. The bridge has recesses on both sides that can interact with locking hooks on the base body. These locking hooks are only arranged on the top side of the base body.

[0003] A multi-part striking plate is also known from DE 299 0318 2 U1. The striking plate shown has a total of three parts and consists of two metal parts, which form the base and cover plates, as well as an end plug, which forms the lateral end of the striking plate. The base and cover plates can be loosely connected during pre-assembly, as the base plate has tenons on one side and the cover plate has corresponding tenon entry openings on one side. After this pre-assembly, the two striking plate parts must be welded together.

[0004] The invention is based on the object of developing a striking plate as mentioned above in such a way that the striking plate is easy to install and ensures robust functionality.

[0005] The problem is solved according to the invention in that the closing recess of the bridge is arranged in a main web which connects two opposite legs, wherein the main web is spaced from the rebate surface and arranged parallel to a support surface located on the base body and the closing recess has an inlet region and a control cam, wherein the control cam branches off from the inlet region and the control cam and inlet region are each arranged closer to one of the two opposite legs of the bridge.

[0006] This design allows the bridge to enclose the base body on both sides with its two legs, ensuring easy installation and a particularly stable hold. The large width of the main bridge compared to the legs provides sufficient space for the locking recess, which can thus provide a large entry area for the sash-side locking pin to enter. The control cam allows the sash-side locking pin to move the sash sufficiently toward and away from the frame.

[0007] According to an advantageous development of the invention, the functional reliability of the striking plate is improved if the inlet area is designed to be as rectangular as possible and extends into one leg, whereby the continuity of the leg is maintained along its length and the inlet area has an extension which is limited by a projection in the direction of the control curve. Thus, the inlet area of ​​the locking recess has the largest possible dimensions. The locking pin can therefore move into and out of the striking plate even if it is not in an ideal inlet position. This means that the sliding window can be opened and closed even under these circumstances. The continuity of the leg maintains the high stability of the striking plate.

[0008] The striking plate offers particularly simple functionality and can withstand high loads acting via the locking pin, especially when the control cam tapers from the inlet area and extends towards the leg at an angle inclined to the longitudinal extent of the bridge until a screw axis forms the central axis of the control cam and the end area of ​​the control cam extends with parallel side walls along this central axis. By arranging the central axis of the end area on a screw axis, which can be formed by two screw connections that connect the striking plate to the frame, the locking pin is held on this screw axis in the locked position. This minimizes potential leverage forces exerted on the striking plate by the locking pin in the opening and closing direction of the sliding window, and thus parallel to the locking pin axis.This makes the strike plate particularly resilient. The aforementioned stress occurs, for example, when someone attempts to force the sliding sash into the open position without authorization. The control cam, with its wide transition from the entry area, allows for the locking pin to enter the door securely.

[0009] According to an inventive development of the striking plate, the guidance of the locking bolt in the control cam is particularly advantageous and the actuating forces particularly uniform if the control cam has a guide edge extending from the inlet area to guide a control bolt guided in the striking plate and the guide edge transitions from a substantially straight edge inclined towards the inlet area into a radius and the radius forms the transition between the straight edge and an edge of the end area, wherein the radius is at least as large as the distance between one edge of the end area and the leg. This shape of the control cam ensures that the sliding sash is evenly attracted to the frame and the forces required when operating the handle are kept to a minimum. The large radius between the straight edge and an edge of the end area ensures a smooth transition.

[0010] The tool-free connection between the bridge and the base body can be further improved if the base body has recesses on two sides that are positioned opposite the raised portions of the bridge. This ensures that the raised portions of the bridge engage with the recesses on the base body as soon as the two parts are connected. This creates a positive connection that secures the bridge and the base body together. This enables particularly simple pre-assembly of both components.

[0011] The assembly of the bridge onto the base body is further facilitated by the lugs located on one side of the base body, which support one leg of the bridge. These lugs can be used as supports when the base body and bridge are first connected using the raised portions. Thus, one leg of the bridge is first positioned on the lugs, and the second leg is pressed onto the base body on the opposite side. This arrangement prevents the first leg from slipping while the second leg is secured.

[0012] The strike plate enables comfortable operation of the sliding hardware if the strike plate is equipped with a buffer stop. This prevents the sliding sash of the window from striking directly against the hard material from which the bridge is made, but instead hits the buffer stop, which is usually made of a soft material, such as rubber. This buffer stop also reduces the mechanical stress on the strike plate, for example, caused by vibrations. This contributes to a longer service life of the strike plate.

[0013] Force dissipation through the stop is particularly effective when the buffer stop is positioned on the base body. Thus, the force when closing the sash is primarily transmitted through the base body and thus to the frame. This increases the damping effect.

[0014] The striking plate is designed particularly compactly if the bridge has a recess in which a stop buffer is located. This design allows the stop buffer to be mounted directly in the surface area of ​​the bridge. The striking plate therefore does not need to have an additional area exclusively for mounting the stop buffer.

[0015] The forces acting on the buffer when the sash closes can be better distributed if the buffer is mushroom-shaped with a head and a web. The head of the buffer protrudes beyond the recess in the bridge. Thus, when the sash closes, the underside of the head is pressed onto the bridge, dissipating part of the force through it. This reduces peak loads on individual components.

[0016] The stability of the stop buffer is further increased by the fact that the web has a funnel-shaped extension, which is spaced from the lower edge of the head at a distance equal to at least the material thickness of the bridge. The web thus has a diameter that varies with the height. The distance, which is at least equal to the material thickness of the bridge, also creates a positive connection between the stop buffer and the bridge.

[0017] In a further embodiment of the invention, the installation of the stop buffer proves particularly simple if the stop buffer is mounted on a cantilever of the base body. The cantilever is located on one side of the base body and does not overlap with the bridge. This means that only one connection between the stop buffer and the base plate needs to be created.

[0018] The invention allows for many embodiments, some of which are shown by way of example in the figures. Fig. 1 a sliding window with a sliding sash and several locking plates according to the invention, Fig. 2 a strike plate according to the invention in an installation situation on the frame of a sliding window, Fig. 3 a perspective view of a strike plate according to the invention in an installation situation on the frame of a sliding window together with some sash-side fittings, Fig. 4 a sectional view of the frame with a locking plate according to the invention along the line IV - IV of Fig. 2, Fig. 5 a first embodiment of a locking plate according to the invention with a locking pin in the closed position in plan view, Fig. 6 the strike plate Fig. 5 in a reverse view, Fig. 7 the strike plate Fig. 5 and Fig. 6 in a perspective exploded view, Fig. 8 a sectional view through the strike plate from Fig. 5. along the line VIII - VIII, Fig. 9 the stop buffer arranged on the strike plate, Fig. 10 an extended embodiment of the locking plate according to the invention from the preceding figures, Fig. 11 shows a further embodiment of the striking plate according to the invention.

[0019] In Fig. 1 shows a sliding window with a sliding sash 2 that can be set aside from a frame 1 and displaced relative to it in a sliding position. In this position, the sliding sash 2 is set aside from the frame 1 so that it can be moved relative to it. In addition, a second immovable sash 3 is arranged in the frame 1. The second sash 3 can also be displaceable in other embodiments. On the underside of the sliding sash 2, carriages 5, 6 are arranged, which are guided in a guide rail, and on the upper side of the sliding sash, two displaceably guided stays 7, 8 are arranged. Schematically, a drive rod fitting 9 with an operable handle 10 is shown. By operating the handle, a longitudinally displaceable drive rod 11 is driven. As a result, arranged on the drive rod 11, Fig. 1, locking pins 37 are moved, which cause the sliding window to close. For this purpose, the locking pins 37 cooperate with locking plates 12 arranged on the frame side on a vertical beam 44, three of which are shown schematically in Fig. 1 are shown.

[0020] The arrangement of the locking plate 12 according to the invention on a vertical beam 44 of the frame 1 is shown in Fig. 2. The striking plate 12 is arranged on a rebate surface 42 in the rebate space of the sliding window. In this view, the multi-part structure of the striking plate 12, consisting of a bridge 13 and a base body 14, can be seen. The base body 14 forms the upper and lower end of the striking plate 12 in this view. Furthermore, the locking recess 17 can be seen, which accommodates the locking pin 37 of the espagnolette fitting 9 as soon as the sliding sash 2 is closed. The bridge 13 has two legs 30, 31, of which leg 31 is visible in this illustration. Furthermore, depressions 22 are formed on the leg 31, which are opposite the elevations 19 shown in later figures on the inside of the legs 30, 31. A stop buffer 16 is arranged on the striking plate 12 in the direction of the sliding sash 2 (not shown).This is made of a rubber-elastic material and serves as an end stop when closing the sliding sash 2. This dampens the mechanical load on the rigid fittings of the sliding fitting.

[0021] Fig. Figure 3 shows the striking plate 12 according to the invention arranged on the frame 1 in perspective in an installed situation together with some sash-side fittings. The stop buffer 16 arranged on the striking plate is opposite the sash-side fittings and serves as the end stop for the closing movement of the sliding sash 2. The sash-side fittings shown comprise the drive rod 11, a faceplate 45, and the locking pin 37. The faceplate 45 serves as a cover for the drive rod 11 arranged below it. This protects it from dirt and external mechanical stress, as well as manipulation. The locking pin 37 is arranged on the drive rod 11 so that it is also moved when the drive rod 11 is moved. For this purpose, the locking pin 37 engages through an elongated hole in the faceplate 45. The locking recess 17 of the striking plate 12 is also shown.The locking pin 37 retracts into this slot when the sliding sash is closed. The illustrated position of the fittings corresponds to a mid-position between the unlocked and locked state of the sliding sash 2.

[0022] Fig. Figure 4 shows a horizontal section along line IV-IV through the vertical transom 44 of frame 1. This section shows the installed state of the striker plate 12 on frame 1 and, opposite, the sash-side fittings arranged on the sliding sash 2. This illustration shows how the locking pin 37 is arranged on the drive rod 11 and extends through the faceplate 45 to interact with the striker plate 12. The striker plate is arranged on the rebate surface 42 of frame 1.

[0023] Fig. 5 shows the striking plate 12 in plan view. The striking plate 12 consists of two parts, the bridge 13 and the base body 14. A main web 34 and two legs 30, 31 form the bridge 13, which has a locking recess 17 with an opening 18, an inlet area 32 and an extension 46. When the sliding sash 2 is closed, the locking pin 37 moves into the largely rectangular inlet area 32 of the locking recess 17 and is then moved along the control cam 33 into the closed position. The locking recess 17 has the opening 18 on the leg 30 of the bridge 13 and the extension 46 on the side opposite the opening 18. The extension 46 is limited by a projection 47, which is located at the transition to the control cam 33. The opening 18 and the extension 46 again enlarge the locking recess 17. This enlargement of the locking recess 17 provides the locking pin 37 with a wide entry area.This means that the sliding sash 2 can be closed without problems even if the locking pin 37 is not in the optimal position, for example due to high external pressure on the sliding sash 2. After the locking pin 37 has been brought into the locking recess 17 by pushing the sliding sash 2 closed, it is guided along the control cam 33 by actuating the handle 10 and subsequently moving the drive rod 11. The control cam 33 has several sections, the first section being formed by a straight edge 38. By being guided along this edge, the locking pin and thus the sliding sash 2 is pulled closer to the frame 1. This is followed by a section which is formed by a radius 39. Due to the large radius 39, the locking pin 37 is forced slowly and smoothly into a movement parallel to the legs 30, 31. Thus, increasingly less stroke is required for the displacement of the sliding sash 2.Instead, this stroke now serves to bring the locking pin 37 into the most secure closed position possible. This position is located in an end region 40 of the control cam 33, which is limited, among other things, by an edge 41. In the illustrated position of the espagnolette fitting 9, the locking pin 37 is located in the end region 40 of the control cam 33 and thus the sliding sash 2 is in its closed state, in which the sliding sash 2 has a tight seal with the frame 1. The bridge 13 and the base body 14 can be connected to one another through the bores 15, for example by screw connections, and screwed to the frame 1. The connecting line 35, which connects the bores 15, forms the central axis of the end region 40 of the control cam 33. This design enables the striking plate 12, in the closed state, to absorb particularly high tensile forces introduced via the locking pin 37.Such forces can occur, for example, during a burglary attempt. The strike plate 12 also has a buffer stop 16. This is arranged on the base element 14 and extends through a recess 24 in the bridge 13. The buffer stop 16 is preferably made of a rubber-elastic material and is intended to ensure a gentle end stop when closing the sliding sash 2. This ensures the ease of use and the longevity of the sliding window.

[0024] Fig. 6 shows the strike plate 12 from Fig. 1 in a rear view. In this view, it can be seen that the bridge 13 has a U-shape and its two legs 30, 31 surround the base body 14 on two opposite sides. In the illustrated embodiment, the bridge 13 has two elevations 19 on each of its two legs 30, 31. These elevations 19 can already establish a reliable force connection between the base body 14 and the bridge 13. As shown in this embodiment, the connection can be improved in that a recess 20, which is arranged on the base body 14, is formed opposite the elevations 19. As a result, a form fit exists between the bridge 13 and the base body 14 in the assembled state, even without any screw connection. The base body also has lugs 21 on one side, which serve as an assembly aid.This allows the first leg 31 to be guided over the side of the base body 14 during assembly of the bridge 13 and the base body 14 and supported by the lugs 21. Subsequently, the second leg 30 can be guided over the second side of the base body 14. Slipping of the first leg 31 is no longer possible during this process due to the lugs 21.

[0025] In Fig. 7 shows a striking plate 12 according to the invention in perspective in an exploded view. For better clarity, the stop buffer 16 is not shown in this illustration. The U-shaped cross-section of the bridge 13 with its two legs 30, 31 is clearly visible in this illustration. The inward-facing elevations 19 are formed into the bridge, which is preferably made of a durable material such as steel, for example by stamping. This process leaves depressions 22 on the outside of the bridge. Furthermore, this illustration shows the bores 23 of the base body 14, which are arranged below the bores 15 of the bridge 13 in the assembled state. These bores are designed to be continuous, so that the screws which connect the bridge 13 and the base body 14 can also be used to fasten the striking plate 12 to the frame.The bridge also has a recess 24 for receiving the stop buffer 16.

[0026] Fig. 8 shows the strike plate from the previous figures in a sectional view along the line VIII - VIII from Fig. 1. This figure also clearly shows the U-shaped cross-section of the bridge 13 and how it encompasses the sides of the base body 14 with its legs 30, 31. The elevations 19 with their associated depressions 22 are also clearly visible. The design of the recesses 20 is also shown. The engagement behind the elevations 19 is created by edges 24 arranged on the sides of the base body 14. During assembly, the elevations 19 are first guided along the outer sides of the edges 24. In this process, the legs 30, 31 of the bridge are pressed outwards against the spring force of the material. As soon as the elevations 19 have passed the edges 24, the legs 30, 31 are pressed back inwards by the spring force, and the elevations 19 lock into the recesses 20.The strike plate 12 can then be arranged at the desired position on the frame 1 and then connected to the frame 1 by a screw connection through the holes 15, 23.

[0027] Fig. 9 shows a stop buffer 16 according to the invention in detail. The stop buffer 16 preferably has a mushroom shape, which is formed by a head 25 and a web 16 and is made of rubber-elastic material. This shape allows the stop buffer 16 to be easily arranged in a corresponding receptacle on the base body 14 and simultaneously has a large stop surface. The stop buffer also has a funnel-shaped extension 27, which is arranged at a defined distance d from the underside of the head 25. The funnel-shaped extension 27 has its base oriented towards the head 25. The distance d is selected such that it corresponds at least to the material thickness of the bridge 13.By arranging the funnel-shaped extension 27 with the aforementioned orientation of the base and the defined distance, the stop buffer can be easily attached to the strike plate 12 even after the bridge 13 and base body 14 have been assembled. The stop buffer 16 is simply pushed through the recess 24 of the bridge 13. Preferably, the difference between the distance d and the material thickness of the bridge 13 lies just above the manufacturing tolerances. Thus, the stop buffer 16 is securely held to the bridge 13.

[0028] Fig. Figure 10 shows an expanded embodiment of the striking plate 12 from the previous figures. The striking plate 12 additionally has a web 28 located on the base body 14. This web 28 serves to further stabilize and dissipate force from the striking plate 12. The web 28 is preferably arranged on the side of the base body 14 where the opening 18 of the locking recess 17 is located. This side of the striking plate 12 is generally facing the person operating the fitting and can be visible when in the open position. In this case, the web 28 also serves as a cover and enhances the appearance of the striking plate 12.

[0029] In Fig.11 shows a further embodiment of a striking plate 112 according to the invention. In this variant, the striking plate 112 further comprises a bridge 113 and a base body 114. Furthermore, an extension arm 129 is arranged on the base body, which extension arm does not overlap with the bridge 113. In this embodiment, the stop buffer 116 is arranged on the extension arm 129. This configuration makes the stop buffer 129 particularly easy to install, since in addition to being arranged on the base body 114, it does not have to be additionally guided through a recess in the bridge 113. Therefore, the work step of milling a recess for the stop buffer 116 is no longer necessary during the manufacture of the bridge 113. QUOTES CONTAINED IN THE DESCRIPTION
