Definitions

  • the invention relates to a forend lever mechanism for selectively locking or unlocking a sash of double-sashed windows, balcony doors or the like, with two connecting rod sections that are longitudinally displaceable and guided in opposite directions to one another on a fixed component, with a pivoted drive lever and with a link for connecting the connecting rod sections to the drive lever. Furthermore, the invention relates to a double-leaf window, balcony door or the like with a locking lever mechanism.
  • Such a forend lever mechanism is, for example, from DE 10 2009 005 342 B4 known.
  • the drive lever is mounted on one of the connecting rod sections and is articulated via a link on the other connecting rod section. By pivoting the drive lever, the distance between the drive rod sections is reduced or increased.
  • a mounting of the drive lever on one of the drive rod sections has a longitudinal guide in a stationary component. As a result, both drive rod sections can also be moved in the same direction with the drive lever in the same position. This makes the operation of the forend lever mechanism particularly uncomfortable.
  • a precisely positioned control of closures via the connecting rod sections is also only possible with difficulty as a result.
  • a faceplate mechanism has become known in which the drive lever can be pivoted on a faceplate section is mounted and drives a single connecting rod via a handlebar.
  • the faceplate section usually covers a fitting groove of the connecting rod, mounting the drive lever on the faceplate section results in very large dimensions. Therefore, such forend lever gears are not arranged at the same height as a drive gear on the other wing.
  • the invention is based on the problem of developing a forend lever mechanism of the type mentioned at the outset in such a way that it is particularly easy to use and has a particularly compact design. Furthermore, a double-leaf window, balcony door or the like, which is particularly easy to operate and has a compact structure, is to be created with such a locking lever mechanism.
  • the first problem mentioned is solved according to the invention in that the drive lever is pivotably mounted on the fixed component and that the drive rod sections are each connected to the drive lever via a link.
  • This design allows the drive lever to be connected to the stationary component via a very compact bearing. Projecting guides or the like are not required thanks to the invention. As a result, the mounting of the drive lever is particularly compact.
  • the positions of the two drive rod sections are also precisely defined relative to one another by the two links, depending on the pivoting angle of the drive lever. This makes the operation of the forend lever gear particularly convenient.
  • the power transmission from the drive lever to the two links could take place, for example, by mounting the links directly on the drive lever.
  • one of the handlebars is closer to the Storage of the drive lever arranged on the fixed component than the other link.
  • a largely uniform driving of both drive rod sections can, however, be easily achieved according to an advantageous development of the invention if a central link is arranged between the drive lever and the two links.
  • the drive of the two connecting rod sections is formed by a three-part link system.
  • the drive of the connecting rod sections is further evened out 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.
  • unauthorized unlocking of the locking lever mechanism by attempting to manipulate the connecting rod sections can be easily avoided if the two links are arranged in a row in the closed position of the locking lever mechanism.
  • the forend lever mechanism is designed to be self-locking.
  • uncomfortable friction when driving the forend lever mechanism can be kept particularly low if the length of the link is greater than the length of the central link.
  • the handlebars which are particularly long as a result, enable an almost straight introduction of force in the direction of movement of the connecting rod sections. Furthermore, this allows the central link to be designed to be particularly short, as a result of which the forend lever mechanism has particularly small dimensions.
  • 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 forend lever mechanism is particularly compact and also has high stability if the drive lever and the connecting rod sections are made of flat material and if the planes of the drive lever are aligned transversely to the planes of the connecting rod sections.
  • tolerances between the fixed component and the connecting rod sections can be easily compensated for if the links are pivotably mounted on bearing blocks and if the bearing blocks are rotatably mounted on the connecting rod sections, with their axes of rotation being arranged perpendicular to one another.
  • the dimensions of the forend lever mechanism are further reduced if the stationary component is designed as a housing frame that encloses the drive lever in the locked position and if the housing frame is flush with a fitting groove that guides the drive rod sections.
  • the sash 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 double-leaf window, French door or the like is achieved according to the invention in that the forend lever mechanism and a drive mechanism of the other wing are arranged at the same height.
  • This design means that both of the gears required to lock the sashes are located at the same height, making them particularly easy to operate.
  • the prerequisite for the arrangement of the two gears is the particularly compact design of the forend lever gear.
  • figure 1 shows a two-wing window without a mullion with two wings 2, 3 hinged to a frame 1 via vertical axes.
  • the wings 2, 3 each have an espagnolette fitting 4, 5 with locks not shown in detail, via which they are locked to the frame 1.
  • One of the espagnolette fittings 4 can be driven via a drive gear 6 by means of a handle 7 .
  • the other of the connecting rod fittings 5 has a faceplate mechanism 8 arranged in a concealed manner in a rebate space located between the wings 2, 3.
  • FIG. 2 shows the drive mechanism 6 and the locking lever mechanism 8 in an enlarged representation with adjacent areas of the wings 2, 3. Wing overlaps for mutual overlapping of the wings 2, 3 are not shown to simplify the drawing.
  • the drive gear 6 drives out via a handle 7 figure 1 connected pinion 9 two connecting rod sections 10, 11 in the same direction.
  • the forend 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 is located in a housing frame 18 which is flush with the one wing 3 and is accessible after the wing 2 which can be locked with the drive mechanism 6 has been opened.
  • the housing frame 18 is firmly connected to one wing 3 . Furthermore, the housing frame 18 closes off a fitting groove (not shown) of the wing 3 .
  • figure 3 shows an enlarged perspective view of the forend lever mechanism 8 in a position that locks a connecting rod fitting 5 .
  • the housing frame 18 encloses the drive lever 12 in the closed position. In this position, the drive lever 12 is only accessible with a gripping element 28 provided 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 connecting rod sections 16, 17, the axes of rotation 24, 25 of the bearing blocks 19, 20 on the connecting 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 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 Forend lever mechanism 8 designed to be self-locking and the connecting rod sections 16, 17 cannot be moved without the central link 13 being driven.
  • the central link 13 is driven by the drive lever 12 being pivoted about a bearing 26 in the housing frame 18 and taking the central link 13 with it.
  • figure 4 shows the forend lever mechanism 8 figure 3 in the unlocked position.
  • the drive lever 12 is opposite the off position figure 3 deflected and pulls the links 14, 15 via the central link 13 in the direction of the housing frame 18.
  • the coupling of the drive lever 12 to the central link 13 takes place via a bearing 27.
  • the bearing blocks 19, 20 and thus the connecting rod sections 16, 17 are pulled together until they collide.
  • the unlocking position of the forend lever mechanism 8 is fixed.
  • the drive lever 12, like the links 14, 15 and the central link 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 in each case
