    Description


    [0001] Manually adjustable air flow regulator in a window ventilation channel and a window, in particular a roof window with a manually adjustable air flow regulator in its ventilation channel.

    [0002] The solution comprises a manually adjustable air flow regulator in a window ventilation channel and a window, and in particular a roof window with a manually adjustable air flow regulator in its ventilation channel with a slider.

    [0003] A solution entailing a ventilation channel in a frame of a roof window featuring a ventilation grille on the ventilation channel outlet was disclosed in patent No. PL183640B1. The ventilation grille includes a hand operated shutter to adjust vent size in the ventilation grille. Vent size is adjusted by moving a hand operated shutter along the horizontal axis. A further example of a ventilation channel can be found in JP H0726581 U.

    [0004] The proposed solution is an alternative solution of the manual air flow adjustment in a ventilation channel. The essence of the solution is a manually adjustable air flow regulator in a window ventilation channel, comprising a housing with at least one longitudinal air vent and a movable shutter characterized in that the housing also features the following:
    • a slider, with a movable coupling to the longitudinal air vent,
    • at least one active element coupled with the slider and the movable shutter,
    • wherein movement of the slider in the air vent along the horizontal axis causes the shutter to move along the vertical axis towards and away from the longitudinal air vent.


    [0005] Preferably the active element includes at least one race for ridges of the movable shutter and is permanently coupled with the slider.

    [0006] Preferably the movable shutter includes at least one race for ridges of the active element permanently coupled with the slider.

    [0007] Preferably the race surface is inclined at α degrees, ensuring the ridge moves smoothly in the race and it is arrested in the race in a defined position.

    [0008] Preferably the movable shutter is at least as long as the air vents of the regulator.

    [0009] Preferably the housing is made out of two elements: back and front, permanently coupled to one another, with the active element and the movable shutter between the two elements.

    [0010] Preferably the housing is made out of two elements: back and front, releasably coupled to one another, with the active element and the movable shutter between the two elements.

    [0011] Preferably, there is a wedging space at the edge of the coupling of the front and back elements, on the inside of the housing, for the edge of the movable shutter also in the shape of a wedge, which blocks the air vent opening in that position.

    [0012] Preferably there is a seal between the housing elements. Preferably there is a recess in the slider for the element moving the slider in the longitudinal air vent. Preferably the slider is a full element, and its side walls constitute surfaces to press for the slider to move along the longitudinal air vent.

    [0013] Preferably the slider surface protruding outward the most is flush with the front housing element.

    [0014] The second aspect of the solution, a window, and in particular a roof window comprises a window frame and a ventilation channel in the window frame with an air inlet on the outside of the premises and an outlet on the inside of the premises, characterized in that it includes a manually adjustable air flow regulator mounted on the window ventilation channel outlet.

    [0015] Preferably there is a seal or sealant between the front housing element of the manually adjustable air flow regulator and the frame.

    [0016] Preferably the front element of the manually adjustable air flow regulator is attached to the window frame using mounting elements.

    [0017] The illustration depicts the solution, with given figures showing the following:

    Fig. 1 exploded view of the manually adjustable air flow regulator according to the first embodiment,

    Fig. 2 perspective view of the manually adjustable air flow regulator according to the first embodiment,

    Embodiment 1



    [0018] The manually adjustable air flow regulator is adapted for mounting in window frame stile 8 with ventilation channel 9. Because the manually adjustable regulator is user operated, it is mounted on the inside of the premises on outlet 11 of a ventilation channel supplying fresh air to the premises through inlet 10 of the ventilation channel. The manually adjustable air flow regulator comprises a housing constituting front 62 and back 61 elements permanently or releasably coupled to one another. Both housing elements feature three longitudinal air vents 1 for the flowing air. One of these air vents 1 features slider 3 with a recess for the user's finger to manipulate the slider so as to allow movement of the slider along air vent 1. There is space between housing elements for movable shutter 2 and active element 4. According to the first embodiment, active element 4 is permanently coupled with slider 3, so that movement of slider 3 results in the same movement of active element 4 in the housing along the horizontal axis. Movement of both these elements results in movable shutter 2 moving along the vertical axis towards and away from air vents 1. Movable shutter 2 is propelled by the movement of slider 3 via active element 4 which includes two races 41 for ridges 21 of movable shutter 2. Race 41 incline angle α is chosen to ensure that ridge 21 moves smoothly in race 41 and that ridge 21 is arrested in race 41 in a defined position. Movable shutter 2 fulfils its air regulating function if its length conforms with the lengths of air vents 1 and in the closed position it covers the entire width of that vent. An edge of the aforementioned movable shutter enters the wedging space between coupled front 62 and back 61 housing elements. Additionally seal 7 mounted on housing perimeter ensures the elements are tight. Once the manually adjustable air flow regulator is fitted and mounted using mounting screws 13 to window frame stile 8 of a roof window it also features seal 12 between window frame stile 8 and front 62 housing element to improve tightness between the regulator and the ventilation channel and thus improve control of air flowing in from the outside.

    Embodiment 2



    [0019] The second embodiment is different from the first embodiment in that the movable shutter comprises two areas, where one fulfils a covering role whereas the other area has two races 22. Active element 5 features two ridges 51 which run along the two aforementioned races 22 so that movement of slider 3 results in ridges 51 of active element 5 moving along races 22 raising or lowering the movable shutter along the vertical axis.
