Definitions

  • the invention relates to a security device for restricting the opening of a window with respect to a window frame.
  • a typical window is rotatable with respect to a window frame about a vertical turning axis.
  • Known security devices comprise a base member that is mounted to the window frame, an attachment member that is mounted to the window and an arm that is rotatably mounted to the base member about a rotational axis parallel to the vertical turning axis of the window.
  • the arm is rotatable towards the attachment member and engages said attachment member.
  • the window can only be opened within a restricted range that is defined by the length of the arm between the base member and the attachment member, e.g. for ventilation purposes, while securing the window against breaking and entering.
  • a special type of window is the so-called 'turn-tilt window', which is not only rotatable about the vertical turning axis, but also about a horizontal tilting axis.
  • the known security devices are incompatible with this special type of window. Hence, there is no secure way of restricting the opening of a turn-tilt window.
  • the invention provides a security device for a window, wherein the window is mounted in a window frame and is rotatable with respect to said window frame about a turning axis extending parallel to and at a first side of the window frame and a tilting axis extending parallel to and at a second side of the window frame, wherein the turning axis extends transverse to the tilting axis, wherein the security device comprises a base member that is arranged to be mounted to a third side of the window frame at an opposite side of the window with respect to the first side of the window frame, an attachment member that is arranged to be mounted to the window near the base member and an arm that is arranged to be rotated with respect to the base member towards the attachment member for engaging the attachment member, wherein security device is provided with a coupling that couples the arm to the base member, wherein the coupling is arranged for rotating the arm with respect to the base member about a first rotation axis that extends parallel to the turning axis of the window and a second rotation axis that
  • the coupling can provide the arm with the rotational degrees of freedom that are required to facilitate both turning and tilting of the window.
  • the security device according to the invention can thus provide a means for restricted opening of a so-called turn-tilt window in both a turned and tilted open position, e.g. for the purpose of ventilation.
  • the attachment member can thus securely engage the arm at the slot to prevent or resist breaking and entering.
  • Providing a number of predetermined, fixed positions for the protrusion head reduces the adjustability.
  • the protrusion head can be more securely received in the respective fixed positions.
  • the protrusion head can no longer be simply displaced in the longitudinal direction of the arm by merely overcoming the friction of a clamping abutment.
  • the position of the protrusion head can be adjusted or fixed, respectively.
  • the arm has an arm body that, in cross section, has an U-shaped profile enclosing the slot and forming two opposite flanges that form a slit along and in communication with the slot, wherein the protrusion body fits at least partially through the slit and extends into the slot to connect to the protrusion head that hooks into the slot, as its diameter is greater than the slit.
  • the security device comprises a fixing member for fixing the position of the protrusion head within the slot along the longitudinal direction of the arm. This makes it possible to restrict the movement of the turn-tilt window in a predetermined number of fixed, intermediate positions along the longitudinal direction of the arm.
  • the fixing member comprises a biasing element that is arranged for biasing the protrusion head to clampingly abut the inside of the slot for fixing the position of the protrusion head within the slot along the longitudinal direction of the arm.
  • the protrusion head can thus be automatically moved into clamping abutment with the inside of the slot.
  • the clamping abutment can provide enough friction and/or resistance between the protrusion head and the inside of the slot to prevent or resist displacement of the protrusion head with respect to the arm in the longitudinal direction of the arm.
  • the protrusion head can be clamped to the inside of the slot along any position within the slot in the longitudinal direction of the arm.
  • the position of the window can thus be steplessly or continuously adjusted.
  • the clamping abutment may reduce rattling noises when the window moves under the influence of wind.
  • the biasing element is arranged for biasing the protrusion head in the retraction direction.
  • the protrusion head can thus be pulled towards the attachment member rather than having to push. Furthermore, attempts to open the window further can result in an even tighter clamping and thus a more secure fixation of the position of the protrusion head within the slot.
  • the fixing member is provided with an operating element that is operationally connected to the protrusion and that is arranged to counteract the bias of the biasing element when operated to terminate the clamping abutment of the protrusion head on the inside of the slot.
  • the operating element When the operating element is operated, the protrusion head can be freely moved through the slot in the longitudinal direction of the arm, thereby temporarily allowing the opening, closing or intermediate positioning of the window.
  • the operating element preferably a button, a slider or a knob
  • Manual operation can be convenient, as it does not require tools such as a key.
  • the fixing member comprises a key operated mechanism, in particular a lock cylinder, that is operationally connected to the protrusion for fixing the position of the protrusion head within the slot along the longitudinal direction of the arm.
  • the fixing member comprising the key operated mechanism can be more secure than the manually operated fixing member because it requires a key to be operated.
  • the key can be stored in a secure location away from the window.
  • the key operated mechanism is operationally connected to the protrusion head to move the protrusion head into abutment or clamping abutment with the inside of the slot.
  • the key operated mechanism can be used to fix the position of the protrusion head in a similar manner and with the same advantageous effects as the manually operated fixing member of the aforementioned embodiments.
  • the coupling comprises a ball joint.
  • the coupling comprises a multi-directional bearing or hinge.
  • the coupling comprises a flexible element. All these couplings can provide at least two rotational degrees of freedom to the arm, including the rotations about the first rotation axis and the second rotation axis.
  • the turning axis extends orthogonal to the tilting axis.
  • the turning axis extends vertical or substantially vertical and wherein the tilting axis extends horizontal or substantially horizontal. This is typically the case for rectangular or quadrangular turn-tilt windows and corresponding window frames.
  • the arm is provided with a release opening that is arranged in communication with the slot at the proximal end of the slot with respect to the coupling, wherein the release opening allows for the release of the protrusion head from the slot.
  • the arm can thus be disengaged from the attachment member only when the window is fully closed and the arm has moved over the attachment member until the protrusion head is at the release opening.
  • the attachment comprises an attachment body, wherein the attachment body is at a distance from the arm when the arm is in engagement with the protrusion, wherein the protrusion is provided with a restricting body extending from the attachment body into the gap between the attachment body and the arm.
  • the restricting body can prevent the insertion of tools, such as screw drivers, prying bars or the like, into the gap between the attachment body and the arm, to prevent manipulation of the arm with respect to the attachment body.
  • the attachment member is alternatively mountable to the third side of the window frame, wherein the base member is alternatively mountable to the window near the alternatively mounted attachment member.
  • This alternative mounting is particularly useful when the security device is mounted to a turn-tilt window that opens to the outside of a building.
  • the arm extends from the base member at the window towards the attachment member at the window frame and swivels away from the window, rather than towards it. It that way, it can be prevented that the arm interferes with the window frame or the window during opening and closing.
  • Figures 1 and 2 show a turn-tilt window 1 mounted in a window frame 2 and provided with a security device 3, in particular a window guard, according to a first embodiment of the invention.

  • the turn-tilt window 1 is mounted in a window frame 2 extending in a vertical or substantially vertical plane, wherein the turning axis R extends vertical or substantially vertical and the tilting axis T extends horizontal or substantially horizontal.
  • the turn-tilt window 1 When rotating the turn-tilt window 1 about the turning axis R, the turn-tilt window 1 can be turned open or closed like a traditional window. When rotating the turn-tilt window 1 about the tilting axis T, the turn-tilt window 1 is tilted open or closed, e.g. for ventilation purposes. In this exemplary embodiment, the turn-tilt window 1 opens towards the inside of a building to which it is fitted.
