Definitions

  • the invention relates to a cuff lever mechanism for selectively locking or unlocking a folded sash of double-leaf windows, balcony doors or the like, the cuff lever mechanism for the folded sash being arranged in a concealed manner in the rebate air between the two sashes, with two on a fixed component that can be moved longitudinally and in opposite directions to one another guided drive rod sections, with a pivotally mounted drive lever and with a handlebar for connecting the drive rod sections to the drive lever, the drive lever being pivotally mounted on the fixed component and that the drive rod sections are each connected to the drive lever via a handlebar. Furthermore, the invention relates to a double-leaf window, French window or the like with a lever mechanism.
  • a lever mechanism is, for example, from DE 198 25 417 A1 known.
  • a forend lever mechanism is disclosed, which includes two links and a drive lever. Both links are rotatably attached to opposite drive rod sections at one of their ends on the wing side. The second end of the first link is further rotatably attached to the second link and the second end of the second link is rotatably attached to the drive lever.
  • Another lever mechanism is, for example, from the DE 10 2009 005 342 B4 known.
  • the drive lever is mounted on one of the drive rod sections and is attached to it via a handlebar other connecting rod section is articulated.
  • the distance between the connecting rod sections is reduced or increased.
  • a bearing of the drive lever on one of the drive rod sections has a longitudinal guide in a fixed component. This means that both drive rod sections can be moved in the same direction with the same position of the drive lever. This makes the operation of the lever mechanism particularly uncomfortable. This also makes it difficult to control closures in a precise position via the connecting rod sections.
  • the invention is based on the problem of developing a lever mechanism of the type mentioned in such a way that it is particularly convenient to use and has a particularly compact structure. Furthermore, a particularly easy-to-use and compact two-wing window, French door or the like is to be created with such a lever mechanism.
  • the first-mentioned problem is solved according to the invention in that a central link is arranged between the drive lever and the two links.
  • the drive lever can be connected to the fixed component via a very compact bearing. Thanks to the invention, extensive guides or the like are not required. This makes the storage of the drive lever particularly compact.
  • the positions of the two drive rod sections are also precisely determined relative to each other by the two links, depending on the pivot angle of the drive lever. This makes operating the lever mechanism particularly convenient.
  • the power transmission from the drive lever to the two handlebars could take place, for example, by mounting the handlebars directly on the drive lever.
  • one of the handlebars is arranged closer to the mounting of the drive lever on the fixed component than the other handlebar.
  • a largely uniform drive of both drive rod sections is achieved by means of a lever mechanism according to the invention.
  • the drive of the two connecting rod sections is formed by a three-part link system.
  • the invention contributes to further equalization of the drive of the connecting rod sections if the distance between a bearing of the drive lever on the fixed component and a bearing of the central link is greater than the length of the central link.
  • tilting moments when pivoting the drive lever can be kept particularly low if two central links are arranged parallel to one another and if the drive lever and the two links are arranged between the parallel central links.
  • the cuff lever mechanism is particularly compact and also has a high level of stability if the drive lever and the drive rod sections are made of flat material and if the planes of the drive lever are aligned transversely to the planes of the drive rod sections.
  • the fixed component is designed as a housing frame that encloses the drive lever in the locking position and if the housing frame is flush with a fitting groove that guides the drive rod sections.
  • the lever gears are usually arranged at a particularly low point on the sash and are therefore uncomfortable to operate.
  • the second problem mentioned namely the creation of a particularly easy-to-use and compact two-wing window, balcony door or the like is solved according to the invention in that the cuff lever gear and a drive gear of the other wing are arranged at the same height.
  • This design means that both gears required for locking the wings are arranged at the same height, making their operation particularly convenient.
  • the prerequisite for the arrangement of the two gears is the particularly compact design of the lever gear.
  • Figure 1 shows a two-wing window without a center post with two wings 2, 3 articulated on a frame 1 via vertical axes.
  • the wings 2, 3 each have a drive rod fitting 4, 5 with locks, not shown, via which they are locked to the frame 1.
  • One of the drive rod fittings 4 can be driven via a drive gear 6 using a handle 7.
  • the other of the drive rod fittings 5 has a cover lever mechanism 8 arranged concealed in a rebate gap between the wings 2, 3.
  • Figure 2 shows the drive gear 6 and the cuff lever gear 8 in an enlarged view with adjacent areas of the wings 2, 3. Wing overlaps for mutual overlap of the wings 2, 3 are not shown to simplify the drawing. It can be seen here that the drive gear 6 and the cuff lever gear 8 are arranged at the same height.
  • the drive gear 6 drives out via a handle 7 Figure 1 connected pinion 9 two drive rod sections 10, 11 in the same direction.
  • the cuff lever mechanism 8 drives two drive rod sections 16, 17 in opposite directions via a central link 13 connected to a drive lever 12 and two links 14, 15.
  • the drive lever 12 lies in a housing frame 18 that is flush with the one wing 3 and is accessible after opening the wing 2, which can be locked with the drive gear 6.
  • the housing frame 18 is firmly connected to one wing 3. Furthermore, the housing frame 18 closes a fitting groove, not shown, of the wing 3.
  • Figure 3 shows an enlarged view of the lever mechanism 8 in a position locking the drive rod fitting 5 in a perspective view.
  • the housing frame 18 surrounds the drive lever 12 in the closed position. In this position, the drive lever 12 is only accessible with a handle element 28 intended for gripping.
  • the two links 14, 15 are pivotally mounted on a bearing block 19, 20 and on the central link 13 via bearings 21 - 23.
  • the bearing blocks 19, 20 are mounted on the drive rod sections 16, 17, with the axes of rotation 24, 25 of the bearing blocks 19, 20 on the drive rod sections 16, 17 and on the links 14, 15 being arranged perpendicular to one another.
  • the bearings 22, 23 of the links 14, 15 on the bearing blocks 19, 20 are in a line with the bearing 21 of the links 14, 15 on the central link 13, so that the links 14, 15 are arranged in a row in the locking position are. That's it Cuff lever gear 8 is designed to be self-locking and the drive rod sections 16, 17 cannot be moved without driving the central link 13.
  • the central link 13 is driven by the drive lever 12 being pivoted about a bearing 26 in the housing frame 18 and thereby taking the central link 13 with it.
  • Figure 4 shows the lever mechanism 8 Figure 3 in the unlocking position.
  • the drive lever 12 is in the off position Figure 3 deflected and pulls the handlebars 14, 15 via the central handlebar 13 in the direction of the housing frame 18.
  • the drive lever 12 is coupled to the central handlebar 13 via a bearing 27.
  • the bearing blocks 19, 20 and thus the drive rod sections 16, 17 are pulled together until they collide. This sets the unlocking position of the lever mechanism 8.
  • the drive lever 12, like the handlebars 14, 15 and the central handlebar 13, is made of flat steel.
  • the material thickness of the drive lever 12 corresponds to twice the material thickness of the individual links 14, 15.
  • a central link 13 is arranged on both sides of the drive lever 12 and the two links 14, 15
