Definitions

  • This invention relates to a handle for doors or windows.
  • the handle according to the invention may be applied on doors or windows made from profiles made of metal, PVC or the like, wood-PVC or the like.
  • the cremone handle comprises a handle or grip, a body handle (prismatic in shape) for containing a kinematic unit designed for converting the rotational movement of the grip (control) into a translational movement for a connecting element protruding from the body handle on the side opposite the one engaged by the grip (usually one or a pair of fins).
  • the connecting element with the handle assembled on the sash, couples with a system for transmitting the movement (usually rods housed in suitable channels of the sash and striker for coupling with the protruding element) to drive the opening and closing of the movable sash of the door or window by movement of pins or bosses relative to contact elements positioned on a fixed frame of the door or window.
  • a system for transmitting the movement usually rods housed in suitable channels of the sash and striker for coupling with the protruding element
  • the kinematic unit housed in the prismatic body comprises a gear wheel connected to the central shaft of the grip.
  • the gear wheel is meshed on one or more racks equipped with one or more corresponding transversal fins, which connect inside with the above- mentioned rods.
  • the gear wheel for moving the fins rotates about an axis of rotation coinciding with the axis of rotation of the grip.
  • Cremone type handles are known from patent documents EP446.566, EP1.387.030 EP1.593.799, all in the name of the same Applicant.
  • the "martellina" handle model is used as an alternative to the cremone handle, especially where there are particular decorative or dimensional requirements (for example, change in colour of accessories, reduced dimensions on doors or windows).
  • the "martellina” handle unlike the cremone handle, has a separate structure between the control grip and the kinematic unit designed to convert the rotational movement of the grip (control) into a translational movement: this solution is used to be able to change, in a fast and economic manner, merely the grip according to the chromatic - decorative requirements of the room in which the door or window is installed.
  • Prior art solutions of "martellina” handle are shown in patent documents EP1.748.127 and WO 2008/081236 in the name of the same Applicant.
  • the kinematic unit (usually called the operating device) can be housed inside the tubular chambers of the profile forming the movable sash of the door or window, whilst only the grip is applied to the outside of the wing of the profile.
  • the grip of the "martellina" handle has a reduced handle body and a protruding connecting element (usually a shaft with a square cross-section) coaxial to the axis of rotation of the handle to which the kinematic unit is mechanically coupled.
  • a protruding connecting element usually a shaft with a square cross-section
  • the square shaft couples in a seat made on a toothed rotor housed inside a box-shaped body forming the frame of the device. It should be noted that the rotor and the square shaft are coupled in a zone inside the tubular section of the profile of the sash, that is, these elements are located at a different height (beneath the channel for housing the operating rods of the sash).
  • the rotor is meshed at least with one rack (if it is a one-way translational movement), positioned coplanar with the channel, and at the ends of which there are pins for connection with the operating rods.
  • the cremone handle has an external kinematic unit which makes it possible to reduce to a minimum the machining inside the profile, it does not affect the tubularity of the profile and it allows a substantially direct connection between connecting element and operating rods with extremely reduced dimensions.
  • cremone handle has large external dimensions and needs extensive machining on the wing of the profile.
  • cremone handle is unlikely to be chosen if the environment in which it is mounted can or must provide for more or less frequent changing of accessories due to requirements of a chromatic nature.
  • the "martellina” handle has a lower cost relative to the cremone handle and a minimum external space: this makes the “martellina” handle a optimum choice for frequent changes of a chromatic type.
  • the "martellina" handle is subject to the presence of the kinematic unit inside the tubular chamber which creates a large internal space and requires invasive and complex machining in the tubular chamber to compensate for the presence of the kinematic unit inside the sash.
  • the aim of this invention is to provide a handle for doors or windows which overcomes the above-mentioned drawbacks of the prior art.
  • the aim of this invention is to provide a handle for doors or windows which can combine minimal machining necessary for assembly on the sash with extremely reduced housing dimensions both for the grip and for the kinematic movement components.
  • a further aim of this invention is to provide a handle for doors and windows which is technically reliable and precise, compact in terms of its functional components and, at the same time, with a high level decorative appearance.
  • the handle for doors or windows which have a movable sash, comprises a grip having a gripping portion and a base portion or neck facing, in use, a part of the outer profile or wing of the movable sash.
  • the grip can rotate about a first axis.
  • the handle also comprises a shaft protruding from the grip and passing, in use, through the outer wing of the movable sash to be coupled (again, in use) to a kinematic unit located close to a longitudinal channel inside the profile of the sash in which at least one control rod slides, connected to the kinematic unit designed to convert the rotational movement of the grip into a translational movement of the rod, in both directions.
  • the handle comprises a first annular kinematic component housed in a seat made in the neck of the grip and having at least one sector with a toothed profile along its circumference, the first component being connected to the neck in such a way as to rotate around the first axis of rotation of the grip.
  • the handle comprises a second kinematic component, comprising a toothed profile, housed in the seat and meshing in an area of the sector with a toothed profile of the first component.
  • the second component is connected to the protruding shaft in such a way as to allow a rotation of the shaft about a second axis parallel to, and different from, the first axis and so as to transmit the rotational movement from the grip to the protruding shaft so as to rotate the latter about the second axis.
  • the shaft which connects the grip to the kinematic unit of translation makes it possible to set up a combined system for moving the rod in very reduced spaces (it all lies between the channel and the outer wing of the sash) without the need for complex machining operations on the tubular portion of the sash and/or on the sliding channel, thus also rationalising the machining on the outer wing.
  • the handle according to this invention combines minimum machining operations on the profile of the sash and very simple installation with a high quality decorative appearance due to the reduced dimensions (grip) and the reduced impact of the parts on view.
  • the first annular kinematic component has the sector with a toothed profile formed on its inner surface facing towards the first axis.
  • the second kinematic component is positioned inside the circular space defined by the first annular kinematic component and meshed on the sector with an internal toothed profile.
  • This architecture for transmitting the internal meshing motion combines a precise movement between grip and shaft thus obtaining a high multiplication of the number of rotations of the shaft (necessary for the stroke of the kinematic unit in order to allow correct opening and closing movement of the sash).
  • the second kinematic component is a gear wheel meshed on the sector with an internal toothed profile of the first kinematic component.
  • the gear wheel is positioned stably in an area of the seat at a fixed radial distance relative to the first axis of rotation of the first kinematic component and of the grip.
  • the second component or gear wheel and shaft are connected to each other and coaxially mounted on the second axis.
  • gear wheel and shaft are positioned along the second axis and radially offset from first axis of rotation (taking as reference the circumference defined by the first kinematic component which is annular in shape and with the centre coinciding with the first axis of rotation).
  • the portion of shaft passing through the outer wing of the sash is positioned, in use, near to a stretch of a free upper surface of the channel.

  • the shaft structured in this way and combined with the cartridge C guides and retains the shaft in all the directions during use.
  • extension S13 of the second kinematic component 13 calculated along the axis X6 below the extension S10 of the first kinematic component 10 increases the possibility of adaptability of the pin 6 to the needs of adjusting the third hexagonal portion 6b.
