Push rod connector and door or window arrangement

Description

[0001] The invention relates to a push rod connector for connecting adjacent push rods of a door or window sash and to a door or window arrangement with such a push rod connector.

[0002] Push rod connectors of the type mentioned above are known from the prior art. For example, EP 1 304 438 A2 discloses a fitting in which a first connecting rod and a second connecting rod (sometimes also referred to as a "push rod") are connected via a toothed shoe with internal teeth. For this purpose, the first connecting rod has an end section with bores into which the toothed shoe is inserted with two pins on its underside. The second connecting rod has longitudinal teeth on its narrow sides that correspond to the internal teeth of the toothed shoe. The second toothed rack can thus be clipped into the toothed shoe in different positions. By adapting the connecting rods, particularly in the area of their coupling sections, the design effort is comparatively high.In addition, such a fitting requires increased space transverse to the longitudinal direction of the drive rod due to the toothed flank shoe that surrounds the second drive rod. A similar design is shown in DE 1 093 698 A.

[0003] DE 25 04 420 A1 discloses a drive rod lock in which two drive rods are connected to one another by means of a toothed engagement part, which is attached to the rear of a drive rod by means of a leaf spring and which can be engaged with an elongated hole provided with teeth corresponding to the toothed engagement part. The toothed engagement part has a tool engagement recess through which the toothed engagement part can be actuated using a tool. If the toothed engagement part is disengaged from the teeth in the elongated hole, the drive rods can be displaced relative to one another. Due to the large number of components, this drive rod lock has a complex structure. In addition, a correspondingly large groove depth in the sash frame is required to perform a length adjustment, for which the toothed engagement part is pushed inward by the faceplate.

[0004] From DE 27 41 408 A1 a corner faceplate and a faceplate rail coupled to the corner faceplate are known, wherein a fine toothing is provided on the faceplate rail.

[0005] EP 0 605 782 A1 discloses two faceplates that can be connected by means of a connecting plate, one faceplate having a slotted hole with a toothing. AT 357 433 B shows a drive rod consisting of two parts that are longitudinally adjustable relative to each other and have toothed coupling surfaces. The drive rod parts engage with the coupling surfaces to prevent relative longitudinal adjustment. A clamp rivet is used to connect the drive rod parts.

[0006] DE 73 10 416 U discloses a connecting rod fitting comprising a movable connecting rod, which in turn is formed from connecting rod sections. The connecting rod sections are provided with fine adjustment means in the form of fine teeth to adjust their length. The invention is based on the object of enabling a length-adjustable connection of adjacent connecting rods using simple structural means. A compact design is desirable.

[0007] The invention solves this problem by means of a push rod connector having the features of claim 1. The push rod connector is designed and / or intended for connecting (adjacent) push rods of a door or window sash. The push rod connector comprises a first connector part, a second connector part, and a fastening element for fastening the connector parts to one another. The connector parts are formed separately from the adjacent push rods. The connector parts overlap one another along a longitudinal direction and, when the fastening element is released, are displaceable relative to one another for adjusting the length of the push rod connector between a retracted position (maximum overlap of the connector parts or minimum length of the push rod connector along the longitudinal direction) and an extended position (minimal overlap of the connector parts or maximum length of the push rod connector along the longitudinal direction).When the fastening element is tightened, the connector parts are fixed relative to one another along the longitudinal direction, so that a length adjustment of the push rod connector made by moving the connector parts relative to one another is maintained. The connecting parts each have a contact surface in their connecting section, against which the connecting parts rest against one another when connected. The contact surfaces each have a profile, at least in sections. The second connector part has a passage for the fastening element. In the first connector part, a fastening opening corresponding to the fastening element is formed, to or in which the fastening element can be fastened. The fastening opening is arranged in the profile. In other words, the fastening opening is formed in a section of the connecting section of the first connector part provided with the profile.

[0008] The push rod connector according to the invention allows for easy adjustment of push rods on door or window assemblies. For example, locking pins attached to the push rod (on the leaf side) can be adjusted relative to strike plates (on the frame side) into which the locking pins are to engage in the closed position. The correct alignment of the locking pin and strike plate is of great importance for reliable locking. A so-called inclusion range of scissors arranged between the frame and leaf of a door or window assembly, or the magnetic positions of locking monitoring devices, can also be easily adjusted.

[0009] The push rod connector can be positioned between two push rods or push rod sections, whereby the push rod connector can connect these push rods or push rods to each other and can also compensate for length differences. The push rod connector is essentially a push rod compensation component. The push rod connector or its connecting components are designed separately from the push rods or drive rods (separately designed components).

[0010] The fastener may optionally include a tool engagement portion for actuating the fastener with a wrench or screwdriver.

[0011] The term "push rod" is used below, whereby such a push rod can be loaded not only with shear (transmission of a compressive force), but also with tensile force (transmission of a tensile force).

[0012] Advantageously, the connector parts can each have a coupling section with a coupling element for suspending a push rod, and each have an adjoining connecting section via which the connecting parts are connected to one another. By arranging the coupling section and connecting section of a connector part one after the other or one behind the other, a comparatively flat overall height can be achieved orthogonally to the longitudinal direction. The coupling element can be designed as a suspension pin, e.g., a round pin. The round pin can have a diameter of 6 mm or 10 mm (millimeters), for example. A push rod to be connected to the coupling section can have a passage, e.g., a punched passage, that corresponds to the coupling element, e.g., the round pin.

[0013] The connecting sections of the connector parts can expediently be connected to one another by means of an eccentric, with the eccentric being coupled to the fastening element. This contributes to a structurally simple and stable, adjustable coupling of the connector parts. The length of the push-rod connector can be adjusted by rotating the eccentric. The fastening element can serve as an adjusting element for the eccentric, for example, via a tool engagement section, as described above.

[0014] The second connector part has a passage for the fastening element, and a fastening opening corresponding to the fastening element is formed in the first connector part, to or in which the fastening element can be fastened. This contributes to a structurally simple and stable fastening, as the second connector part is fastened to the first connector part by means of the fastening element.

[0015] Specifically, the fastening element can be designed as a screw, and the fastening opening can be designed as a threaded hole. This creates a force-locking fastening. The threaded hole can be designed as a blind hole or a through hole with an internal thread. The threaded hole or internal thread and the screw fit together, allowing the screw to be screwed into it and secured.

[0016] Advantageously, the passage can be designed as an elongated hole. This contributes to simple structural adjustment, since the connector parts can be moved relative to each other when the fastening element is loosened and secured together in the desired position by tightening the fastening element, e.g., a screw.

[0017] The passage can expediently have a circumferential chamfer at the end facing away from the first connector part, wherein the chamfer is continuous (chamfer at the passage continuously circumferential) and the fastening element has a head section with a chamfered section corresponding to the chamfer. This contributes to a large contact area between the chamfer and the chamfered section while at the same time maintaining a low height (orthogonal to the longitudinal direction). The continuous chamfer enables fine adjustment of the connector parts relative to one another. Depending on whether profiling is provided on the contact surfaces of the connector parts, adjustment can be made in fine steps (profiling present and steps dependent on the design of the profiling) or continuously (no profiling present).If the fastening element is designed as a screw, the head section with a chamfered section can be a screw with a countersunk head.

[0018] Alternatively, the passage can have a circumferential chamfer at the end facing away from the first connector part, wherein a plurality of countersinks are formed on the chamfer, which countersinks overlap one another, in particular along a central longitudinal direction of the passage (e.g. formed as an elongated hole) or the longitudinal direction (overlapping or overlapping countersinks), wherein the fastening element has a head section with a chamfered section corresponding to the chamfer and / or one of the countersinks. This contributes to a comparatively large contact surface. The countersinks formed on the chamfer enable a stepped adjustment of the connector parts relative to one another. The grading is predetermined by the number and / or the spacing of the adjacent countersinks. If the fastening element is designed as a screw, the head section with the chamfered section can be a screw with a countersunk head.The screw can be positioned in different countersunk positions to adjust the connector parts relative to each other.

[0019] The connecting parts each have a contact surface in their connecting section, on which the connecting parts rest against one another in the connected state, wherein the contact surfaces each have a profile, at least in sections.

[0020] This allows for a positive connection between the components. When the connecting sections are in contact with each other, the profiles interlock in such a way that, when the fastening element is released, the connecting parts can only be moved relative to each other if, for example, the second connector part is raised relative to the first connector part. This reduces the risk of unwanted adjustment of a previously set length.

[0021] Specifically, the profiling can be designed as a toothing. This allows for a structurally simple and stable connection. The toothing can be designed similarly to a rack section. The tooth flanks of the toothing can extend transversely or diagonally to the longitudinal direction. This allows for a stepped adjustment of the connecting parts relative to each other, with one adjustment step corresponding to the tooth spacing between two adjacent teeth.

[0022] In a suitable manner, the connector parts, in the connected state (connector parts with connecting sections positioned on top of one another and fastening element tightened), can rest with the underside of their coupling sections on a common plane, wherein the connecting section of the first connector part is in particular aligned with the coupling section of the first connector part, wherein the connecting section of the second connector part is offset relative to the coupling section, so that the connecting section of the second connector part at least partially covers the connecting section of the first connector part. This contributes to a stable and compact design. The coupling sections and any push rods coupled thereto can thus be aligned. This allows a simple design of a wing-side receiving groove and smooth sliding of the push rod connector in the groove.

[0023] Advantageously, the first connector part and / or the second connector part can each be made of die-cast zinc. This allows for a sufficiently stable design with efficient production, particularly by means of a zinc die-casting process. The first connector part and / or the second connector part can alternatively be made of steel or aluminum, particularly by means of a steel or aluminum casting process. A design using metal or plastic 3D printing is also conceivable. A design made of plastic with or without fiber reinforcement is also possible.

[0024] In a preferred embodiment, the first connector part and the second connector part can each have narrow sides and flat sides, with the flat sides being several times larger than the narrow sides. This allows for a space-saving arrangement of the push rod connector on a casement, for example, in a groove provided on the casement for accommodating push rods. The push rod connector can also be arranged in this groove.

[0025] The contact surfaces can be conveniently formed on the flat sides. This allows for comparatively large contact areas. This contributes to a reliable fit between the connector parts.

[0026] As explained above, the connecting parts each have a contact surface in their connecting section, against which the connecting parts abut one another in the connected state, wherein the contact surfaces, at least in sections, each have a profile. The connecting parts, in particular their connecting sections, and / or the profiles are designed such that the profiles are visible from the side, i.e., from the narrow sides. This contributes to easy adjustability of the push rod connector. The object mentioned above is also achieved by a door or window arrangement having the features of the independent claim 13.

[0027] The door or window assembly comprises a frame and a sash (door or window sash) mounted on the frame for pivoting and / or tilting. The sash has two push rods that can be actuated by means of a handle. These push rods are slidably guided in a sash groove and arranged adjacent to one another or one behind the other along the longitudinal direction of the groove. The door or window assembly further comprises a push rod connector according to the invention. The push rod connector is arranged at least largely between the push rods along the longitudinal direction of the groove (overlap between push rods and push rod connector is possible), and the push rods are connected to one another by means of the push rod connector.

[0028] With regard to the advantages that can be achieved with this, reference is made to the relevant comments on the push rod connector.

[0029] The door or window sash can, in particular, be designed as an aluminum sash. The aluminum sash has a sash groove, which can, for example, be designed as a C-groove.

[0030] The push rod connector can be positioned anywhere on the sash. The push rod connector can be used multiple times if necessary. For example, an installed push rod connector can be removed and then reinstalled in the same or a different location. Regardless of this, it is conceivable that multiple push rod connectors are used or installed on a door or window sash.

[0031] The invention will be explained in more detail below with reference to the figures, in which identical or functionally identical elements are provided with identical reference numerals, if necessary, but only once. They show, in a perspective view, Fig.1 a section of a door or window sash with a push rod connector and two connected push rods; Fig.2 the push rod connector from Fig.1 with two connected push rods in a standalone position; Fig.3 the push rod connector from Fig.1 in an exploded view; Fig.4 the push rod connector from Fig.1 in a side view; Fig.5 the push rod connector from Fig.1 in a neutral position ( Fig.5a ), an extended position ( Fig.5b ) and a retracted position ( Fig.5c ); and Fig.6 a possible design of the push rod connector from Fig.1 with countersinks in neutral position in a perspective view ( Fig.6a ), a top view ( Fig.6b ) and the second connector part in a perspective view in isolation.

[0032] Figur 1 shows a door or window arrangement 100 with a frame (not shown) and a wing 102 pivotably and / or tiltably mounted on the frame (door or window wing; in Figur 1 only partially shown). The wing 102 has two push rods 104, 106 which can be actuated by means of a handle (not shown), which are displaceably guided in a wing groove 108 and arranged adjacent to one another along the groove longitudinal direction 110.

[0033] The handle can be coupled to the push rods 104, 106, for example, by means of a push rod mechanism (not shown). The push rod mechanism can be configured such that a rotary movement of the handle (rotation) is converted into a translational movement of the push rods 104, 106 (push rods 104, 106 are displaced along the groove longitudinal direction 110).

[0034] The door or window assembly 100 further includes a push rod connector 10, which is arranged along the groove longitudinal direction 110 between the push rods 104, 106 and connects the push rods 104, 106 to one another. The push rod connector 10 is largely arranged between the push rods 104, 106, with the push rods 104, 106 and the push rod connector 10 partially overlapping. The push rod connector 10 is formed separately from the push rods 104, 106.

[0035] Figur 2 shows the push rod connector 10 with connected push rods 104, 106 in isolation. The push rod connector 10 is explained in more detail below.

[0036] The push rod connector 10 is designed and intended for connecting adjacent push rods 104, 106 of a door or window sash 100. The push rod connector 10 has a first connector part 12, a second connector part 14, and a fastening element 16 for fastening the connector parts 12, 14 to one another.

[0037] The connector parts 12, 14 overlap each other along a longitudinal direction 18 and, when the fastening element 16 is released, are movable between a retracted position (cf. Fig.5c ) and an extended position (cf. Fig.5b ) can be moved relative to each other.

[0038] In the retracted position, the connector parts 12, 14 overlap each other to a maximum extent. The push rod connector 10 then has a minimal length along the longitudinal direction 18 (see Fig.5c ). In the extended position, the connector parts 12, 14 overlap each other minimally. The push rod connector 10 then has a maximum length along the longitudinal direction 18 (cf. Fig.5b ).

[0039] When the fastening element 16 is tightened, the connector parts 12, 14 are fixed relative to one another along the longitudinal direction 18, so that a length adjustment of the push rod connector 10 made by moving the connector parts 12, 14 relative to one another is maintained.

[0040] In the example, the connector parts 12, 14 each have a coupling section 22, 24 with a coupling element 26, 28 for suspending a push rod 104, 106 and a connecting section 32, 34 adjoining the coupling section 22, 24, via which the connector parts 12, 14 are connected to one another (cf. Fig.3 ). The coupling elements 26, 28 in the example are designed as suspension pins in the form of round pins. The push rods 104, 106, which are to be connected to the coupling section 22, 24, each have a through-hole 112, 114, for example a punched one, which corresponds to the coupling element 26, 28, in the example the round pin (cf. Fig.2 ).

[0041] Instead of designing the coupling elements 26, 28 as conventional round pins, a round pin with lateral recesses can be used. The round pin has a substantially oval shape when viewed from above (e.g., similar to a 400-meter track in a multi-purpose stadium). This allows for material savings on the round pins. The passages 112, 114 are designed with lateral recesses corresponding to these round pins.

[0042] In embodiments not shown, the connecting sections 32, 34 of the connector parts 12, 14 can be connected to one another by means of an eccentric, wherein the eccentric is coupled to the fastening element 16 (not shown).

[0043] In the present example, the second connector part 14 has a passage 38 for the fastening element 16 and in the first connector part 12 there is formed a fastening opening 36 corresponding to the fastening element 16, to or in which the fastening element 16 is or can be fastened (cf. Fig.3 ).

[0044] In the example, the fastening element 16 is designed as a screw and the fastening opening 36 is designed as a matching threaded hole (blind hole or through hole with internal thread).

[0045] The passage 38 in the second connector part 14 is formed as an elongated hole. The passage 38 has a circumferential chamfer 40 at the end facing away from the first connector part. The fastening element 16 has a head portion 42 with a chamfered portion 44 corresponding to the chamfer. In the example, the head portion 42 and the chamfered portion are designed as countersunk heads.

[0046] In the example, the connecting parts 12, 14 each have a contact surface 46, 48 in their connecting section 32, 34, against which the connecting parts 12, 14 abut one another in the connected state. The contact surfaces 12, 14 each have, at least in sections, a profiling 50, 52. In the example, the profiling 50, 52 is each formed as a toothing. The tooth flanks of the toothing extend transversely to the longitudinal direction 18 (cf. Fig.3 ). In the example, the fastening opening 36 is arranged in the profile 50 of the connecting section 32 of the first connector part 12. The connecting sections 32, 34 and / or the profiles 50, 52 are each designed such that the profiles 50, 52 are visible from the side, ie, from the narrow sides S.

[0047] In the connected state, the connector parts 12, 14 lie with the underside of their coupling sections 22, 24 on a common plane E (cf. Fig.4 ). In the example, the connecting section 32 of the first connector part 12 adjoins the coupling section 22 of the first connector part 12 in a line. The connecting section 34 of the second connector part 14 is offset relative to the coupling section 24, so that the connecting section 34 of the second connector part 14 at least partially covers the connecting section 32 of the first connector part 12. The coupling sections 22, 24 and the push rods 104, 106 possibly coupled thereto can thus be located within a line (cf. Fig.4 ).

[0048] In the example, the first connector part 12 and the second connector part 14 are each made of die-cast zinc.

[0049] In the example, the first connector part 12 and the second connector part 14 each have narrow sides S and flat sides F, wherein the flat sides F are many times larger than the narrow sides S. The contact surfaces 46, 48 are formed on the flat sides F (cf. Fig.3 ).

[0050] Fig.5a shows the push rod connector 10 in a neutral or center position. The connector parts 12, 14, or their connecting sections 32, 34, largely overlap each other. The screw 16 is located centrally in the elongated hole 38. The push rod connector 10 has a medium length.

[0051] Fig.5b shows the push rod connector 10 in the extended position. In the extended position, the connector parts 12, 14 overlap each other minimally. The second connector part 14 is displaced relative to the first connector part 12 so that the screw 16 on the (in Fig.5b ) left end of the elongated hole 38. The push rod connector 10 then has a maximum length along the longitudinal direction 18.

[0052] Fig.5c shows the push rod connector 10 in the retracted position. In the retracted position, the connector parts 12, 14 overlap each other to the maximum. The second connector part 14 is displaced relative to the first connector part 12 so that the screw 16 on the (in Fig.5b ) right end of the elongated hole 38. The push rod connector 10 then has a minimal length along the longitudinal direction 18.

[0053] The Figuren 6a bis 6c show a possible design of the push rod connector 10. The push rod connector 10 largely corresponds to the embodiment described above, so that reference is made to the explanations there to avoid repetition.

[0054] Deviating from this, on the second connector part 14, the passage 38 has a circumferential chamfer 40 at the end facing away from the first connector part 12, wherein a plurality of countersinks 41 are formed on the chamfer 40 (cf. Fig.6c ). The countersinks 41 overlap each other along the longitudinal direction 18 or along the central longitudinal direction of the passage 38, which in the example is designed as an elongated hole.

[0055] The fastening element 16 has a head section 42 with a chamfered section 44 corresponding to the chamfer 40 or the countersinks 41 (cf. Fig.6c ). In the example, the head section 42 and the chamfered section 44 are designed as countersunk heads. The fastening element 16 is thus designed as a countersunk head screw.

[0056] Fig.6a und 6bshows the push rod connector 10 in a neutral or center position. The connector parts 12, 14, or their connecting sections 32, 34, largely overlap each other. The screw 16 is located centrally in the elongated hole 38, with the screw 16's chamfered section 44 resting in the center counterbore 41 in the example. The push rod connector 10 has a medium length. To adjust the connector parts 12, 14 relative to each other, the screw 16 can be loosened and, after adjusting the connector parts 12, 14, tightened again, whereby the chamfered section 44 comes into contact with another of the counterbores 41.
