Definitions

  • the invention relates to a gear mechanism of a fitting for a window, a door or the like, with a gear housing, at least a drive rod and a drive gear, the teeth of which Comb the recesses in the drive rod.
  • the invention further relates a fitting for a window, door or the like, the includes such a transmission.
  • the invention is therefore based on the object of a transmission or to create a fitting of the type mentioned, the one Have a locking function and are simply constructed.
  • the locking device Since the locking device is therefore located in or on the gear housing, it does not require a structurally complex design or Storage of the control handle. Furthermore, the installation space is in the gear housing accordingly large, so that the locking device there easy to place and functionally safe.
  • the locking device has an elastically resilient locking projection has that for locking with a locking recess of Driving rod interacts, which the locking projection in the respective Rest position of the drive rod is opposite.
  • An advantageous embodiment of the invention also provides that the locking projection in the direction of the locking recesses or recesses the drive rod is resiliently biased, where appropriate arranged on a spring plate and in particular in one piece is formed with the spring plate.
  • the formation of the locking projection can, for example, by shaping a nose the spring plate are generated, which expediently one has a flat U-shaped cross section, the yoke of the latch carries and whose legs are held by the gear housing.
  • the locking recess one of the with the drive gear and / or the coupling gear of the gear meshing recesses of the drive rod is formed.
  • the coupling gear meshes with a plurality of coupling gear recesses designated recesses of the drive rod, the same as those meshing with the drive gear and recesses referred to as drive gear recesses the drive rod in relation to the locking device along the Driving rod are arranged that the locking projection in a locking position with one of the drive gear recesses and in one another locking position with one of the coupling gear recesses interacts.
  • the locking projection between two neighboring ones Locking positions in another of the drive gear recesses or the coupling gear recesses engages and the drive rod is locked to the gearbox is finally provided that the locking projection between the two neighboring Locking positions none of the drive gear recesses or opposite the coupling gear recesses.
  • the two locking positions opposite the two Correspond to the end positions of the window or door handle preferably exists between the first or the end Drive gear recess and the adjacent last or end coupling gear recess, each with the locking projection engage, a distance equal to the maximum stroke corresponds to the connecting rod.
  • the distance mentioned preferably corresponds to a maximum Angle of rotation of the drive gear of 90 °, this angle expediently about 4 to 5 and preferably 4.4 tooth periods of the Drive gear corresponds.
  • the drawing illustrates the invention using an exemplary embodiment, the single figure is a sectional view through a Gear of a window or door fitting shows.
  • the expanding gear 1 shown in the drawing of a fitting for a rotating wing of a window or a door has a gearbox 2, in which a drive gear 3 and a coupling gear 10 around two spaced parallel axes of rotation 4 and 18 are rotatably mounted.
  • a gearbox 2 in which a drive gear 3 and a coupling gear 10 around two spaced parallel axes of rotation 4 and 18 are rotatably mounted.
  • the gear housing 2 further contains a locking device 15 housed inside, which in two opposite, the opening or closing position of the Window or door fittings corresponding end positions of the Driving rods 5, 6 engages with one of the driving rods 6 in order to Driving rod 6 in the open or closed position of the window or To lock the door fitting with the gear housing 2.
  • the gear housing 2 consists essentially of two in plan view mirror-symmetrical housing halves 20, of which in the Drawing only one is shown.
  • the gear housing has a seat 24 for detachable Insert the locking device 15 on.
  • the two housing halves 20 are after the insertion of the drive rods 5 and 6, the drive gear 3, the coupling gear 10 and the locking device 15 assembled and firmly connected.
  • the drive gear 3 has two surrounding the passage opening 19 and protruding on its opposite ends cylindrical trunnion 24 (only one visible), which in one Pair of opposite bearing recesses of the housing halves 20 intervene. In the axial direction between the two journals 24 is the drive gear 3 with a radially protruding Circle segment-like flange 25 provided between two parallel inner walls of the housing halves 20 slidably is.
  • the flange 25 is on its outer circumference Angle of approximately 90 °, corresponding to approximately a quarter circle segment, provided with a total of five protruding teeth 7, which at Turn the drive gear 3 with drive gear recesses 8 Comb a longitudinal toothing of the drive rod 6 and thereby the drive rod 6 depending on the direction of rotation of the drive gear 3 in the direction of arrow A or B. relocate.
  • the axis of rotation 4 of the drive gear 3 is on the nut side arranged by the drive rod 6.
  • the distance from the drive gear 3 inside the gear housing 2 arranged coupling gear 10 also instructs two cylindrical protruding from its opposite ends Hinge pin 26 (only one visible) on the other pair of opposite bearing recesses of the housing halves 20 intervention.
  • the coupling gear 10 is on its entire circumference provided with teeth 27, the number in the illustrated embodiment is six. Of these teeth 27 comb each one to two on one side of the coupling gear 10 with coupling gear recesses 11 a further longitudinal toothing of drive rod 6 driven by drive gear 3. On the opposite one Side of the coupling gear 10 also comb one to two of the teeth 27 with coupling gear recesses 12 a longitudinal toothing of the other drive rod 5.
  • the distance of the Recesses 12 correspond exactly to the distance between the recesses 11, which is currently meshing with the coupling gear 10 standing recesses 11 and 12 from the axis of rotation 18 of the Coupling gear 10 seen from diametrically opposite Sides lie.
  • the drive rod 5 is at an axial displacement of the drive rod 6 axially displaced by the same amount as this, but in the opposite Direction.
  • the coupling gear wheel recesses 11, 12 are each so in the end region the drive rods 6 and 5 arranged that they are accurate opposite each other when the drive rods 5 and 6 in one in the Middle position between their two end positions are located.
  • the coupling gear recesses 11 on the drive rod 6 are also arranged such that a distance X between the center of the last coupling gear recess seen from the left 11 and the first drive gear recess 8, i.e. of the two adjacent innermost recesses 11 and 8, the maximum stroke of the connecting rods 5, 6 between their two End positions and an angle of rotation of the window or door handle or the drive gear 3 corresponds to 90 °.
  • this distance X 4.4 tooth periods the drive gear 3.
  • the area 14 between the drive gear 3 and the coupling gear 10 arranged locking device 15 consists essentially from a leaf or catch spring made of spring steel 16, which integrated an integrally formed with the detent spring 16 Has latch 17.
  • the detent spring 16 has an essentially U-shaped cross-sectional profile, the legs 18 and 19 in pockets engage in the seat 24 of the gear housing 2 and whose yoke in the middle of its outer side facing the drive rod 6 with the hump-shaped pressed out of the spring steel Latch 17 is provided.
  • the latch 17 is by the Elasticity of the detent spring 16 in the first seen from the left Drive gear recess 8 of the drive toothing Push rod 6 pressed while turning the control handle and the drive gear 3 by 90 ° in the open position in the adjacent last coupling gear recess 11 of the Coupling teeth of the drive rod 6 is pressed and thus in these end positions, the drive rod 6 in relation to the gear housing 2 locked.
  • the locking also makes an unwanted one Turn back the drive gear 3 and the coupling gear 10 prevented.
  • the invention is in particular for rotating sashes of windows, doors and the like, in which the drive gear 3, also called nut, by 90 ° from the closed position to the open position rotates.
  • the drive gear 3 also called nut
  • the connecting rod 6 is in relation locked to gear housing 2.
  • the invention is of course not limited to that the drive rod 6 is only locked in its end positions, but other configurations are also conceivable.
  • a further recess or recess in the drive rod 6 may be provided, for example around the drive rod 6 in the tilted position of a window or door leaf with the gearbox 2 to lock.
