Definitions

  • the invention relates to a drive gear for a connecting rod fitting of a window, a window door or the like, with a drivable nut and a gear for driving a driving rod that can be driven by rotating the nut, with a first lever and with a second lever of the gear pivotably mounted on the first lever , wherein the levers are arranged to form a toggle lever and the levers are connected to a crank pin guided in a link.
  • the JP H08 82140 A discloses a drive gear with a lever assembly drivable by a nut. Several pins of the lever arrangement are guided in a guide. The lever assembly can be moved from an extended position to a contracted position by driving a nut.
  • Such a drive transmission is for example from EP 2 366 855 B1 known.
  • the first lever protrudes from the nut, while the second lever is hinged to a slide.
  • the two levers thus form a crank mechanism for driving the slide.
  • the slide drives a gear, which in turn drives part of the drive rod. If the levers are at a right angle to one another, the slide and thus the drive rod are moved further with a fixed deflection of the nut than with an almost straight arrangement of the levers to one another. An intended course of the movement of the drive rod via the rotational movement of the nut cannot be set as a result.
  • a drive gear is also known in which two levers are combined to form a crank mechanism and can be driven by a nut.
  • a pinion meshing with the drive rod is driven via this crank mechanism.
  • the displacement path of the connecting rod is very much dependent on the rotary position of the nut.
  • the invention is based on the problem of developing a drive gear of the type mentioned at the outset in such a way that it enables a free translation of the drive movement of the drive rod when the nut is rotated and has particularly small dimensions.
  • the translation of the drive movement of the drive rod when the nut is rotated can be easily adjusted by means of a suitable course of the link.
  • the movements of the levers are controlled by the course of the backdrop via the crank pin.
  • An envisaged transmission ratio between the nut and the movement of the section of the drive rod can be easily set, for example, via the length ratio of the lever and the type of drive of the lever via the nut.
  • the drive transmission thus also has particularly small dimensions.
  • the drive gear enables particularly smooth locking of the drive rod fitting because the link has a first section inclined to the intended direction of movement of the drive rod and an adjoining second section inclined opposite to the first section. As a result of this design, the drive gear has a variable translation when driving the drive rod.
  • the guide of the crank pin in the first section can be arranged directly at the closed position if several closures of the drive rod fitting are moved into the locking position via the movement of the drive rod.
  • the crank pin can be guided in the second section when the locks are separated from one another, since in this position the frictional resistance of the drive rod fitting is particularly low.
  • the drive gear is particularly compact because the nut has a drive pinion and the drive pinion is coupled to a slide and the first lever is articulated on the slide and the second lever has a bearing for articulation on the drive rod.
  • the size of the drive pinion can also be used to set the displacement path of the slide as a function of the rotation of the nut and thus the transmission ratio of the drive gear.
  • the slide is guided on the drive rod and has a series of recesses into which the drive pinion engages.
  • One of the levers could, for example, have a projection as a crank pin with which it is guided in the link.
  • the drive gear is designed according to another advantageous development of the invention in a structurally particularly simple manner if a bearing pin connecting the two levers is made in one piece with the crank pin.
  • An envisaged path of the drive rod can be easily adjusted according to the invention in that the link has a third section which is arranged parallel to the direction of movement of the drive rod and which adjoins the second section.
  • the crank pin is guided in the third section when the drive rod fitting is driven from a rotary position into a tilted position.
  • the drive gear can be arranged in particularly flat recesses in the window if a section of the drive rod is designed in the shape of a trough to accommodate the slide.
  • the spatial assignment of the bearing of the nut and the guide of the crank pin can easily be determined according to another advantageous development of the invention if a housing has a housing base and a housing cover, if at least one of the components of the housing base or the housing cover has a bearing shell for the nut and has a recess for the backdrop.
  • the drive gear has a particularly high level of stability.
  • the housing has a guide for the slide and for the drive rod.
  • the guides are preferably formed by bends of at least one of the components of the housing base or the housing cover. This helps to further increase the stability of the drive gear.
  • Figure 1 shows a window with a frame 1 and a sash 2 and with a connecting rod fitting 3 for locking the sash 2 in the frame 1.
  • the sash 2 can be pivoted about a vertical axis 4 with respect to the frame 1 into a rotary position and about a horizontal axis 5 tilt with respect to the frame 1 in a tilted position.
  • the drive rod fitting 3 can be driven via a handle 6 and has a drive rod 7 for driving several locks 8.
  • the handle 6 In the illustrated position, the handle 6 is in position "Z", which indicates the closed position in which the leaf 2 is in the frame 1 and is locked via the locks 8.
  • the handle 6 can be moved into a rotary position “D” in which the wing 2 can be rotated about the vertical axis 4.
  • a position “K” of the handle 6 the wing 2 can be tilted about the horizontal axis 5 with respect to the frame 1.
  • FIG 2 shows a drive gear of the espagnolette 3 from Figure 1 in the closed position in which the handle 6 is in position "Z".
  • the drive gear 9 has a nut 11 rotatably mounted in a housing 10 for attaching the in Figure 1 handle 6 shown and a portion of the drive rod 7.
  • the housing 10 has a housing bottom 26 arranged parallel to the plane of the drawing and a housing cover with a bearing shell (not shown) for mounting the nut 11, which is manufactured in one piece with the drive pinion 13. To simplify the drawing, the housing cover is not shown.
  • the drive gear 9 has a gear 12 with a drive pinion 13 arranged concentrically to the nut 11 for driving a slide 14 and with a toggle lever 17 formed by two levers 15, 16.
  • the slide 14 has a series of recesses 18 which the drive pinion 13 meshes with .
  • a first lever 15 of the toggle lever 17 is articulated on the slide 14, while the second lever 16 is articulated on the section of the drive rod 7.
  • the levers 15, 16 are connected to one another via a bearing pin 19.
  • a crank pin 20 is made in one piece with the bearing pin 19 and is guided in a link 21.
  • the gate 21 is designed as a recess 27 in at least the housing bottom 26 of the housing 10.
  • the housing 10 also has a guide 22, 23 for the slide 14 and for the section of the drive rod 7.
  • the slide 14 is guided on the section of the drive rod 7.
  • the drive rod 7 is designed in the shape of a trough to accommodate the slide 14.
  • the first lever 15 has a bearing 24 on the slide 14 and the second lever 16 has a bearing 25 on the section of the drive rod 7.
  • the gate 21 has a first section 28 inclined to the intended direction of movement of the section of the drive rod 7 and a second section 29 inclined opposite to the first section 28.
  • a third section 30 of the gate 21 is arranged parallel to the direction of movement of the section of the drive rod 7 and joins the second Section 29. In the illustrated closed position, the crank pin 20 is located at the end of the first section 28.
  • Figure 5 shows the course of the translation I of the drive gear 9 when the handle is driven from the “Z” position through the “D” position into the “K” position. Between the “K” position and the “D” position, the drive gear 9 has a constant gear ratio. If, starting from position “D”, the drive gear 9 is moved in the direction of the locking position “Z”, a very high gear ratio is first achieved, which means that initially with a slight rotation of the nut 11 there is a large displacement of the drive rod 7. Only when the crank pin 20 is in the first section 28 of the link 21 is the portion of the drive rod 7 driven with a low gear ratio. This means that a large rotation of the nut 11 only leads to a small displacement of the section of the drive rod 7.
  • Figure 6 shows the course of the longitudinal movement x of the section of the drive rod 7 when the nut 11 is rotated through the positions "K", "D” and "Z".
