Definitions
- the present invention relates to an arrangement in a lamell Venetian blind which is provided between the window panes a double-glazed window, with a device for turning the lamell about its longitudinal axis and to displace it across sai axis, in which the lamellae are mounted at their ends in t opposite window frame sides, in guides permitting movement the lamellae across their longitudinal direction b preventing movement in the longitudinal direction, and i which elongated driving means are provided at two opposit frame sides to extend in parallel with the frame sides, whic means are driven by at least one motor and are designed t cause synchronous movement of the lamellae ends across thei longitudinal direction.
- Venetian blinds have been known and used for a lon time. Such Venetian blinds mainly serve two purposes, viz screening against observation and screening against to strong sunlight, also they serve as a thermoshade to improv heat insulation of the window.
- Venetian blinds which are mounted outside window are known, e.g. from EPC application 0109382.
- the previously known Venetian blinds were driven by cord drives.
- window which has Venetian blinds that are suspended by cords may only be vertically mounted. Such windows, thus, cannot be mounted in an inclined or horizontal position, and the cannot be used for skylights and the like.
- Figure 1 is a diagrammatical view of a window wit insulation glass, which is provided with venetial blind according to the invention
- Figure 2 shows a detail at the end of both parall spindles
- Figure 3 shows the end of the threaded portion of spindle in more detail
- Figure 4 is a cross sectional view of a frame side i which the spindle is mounted
- FIG. 5 is a diagrammatical view of the drive means fo the spindles
- Figure 6 shows the free running arrangement of on spindle
- Figure 7 shows one single lamella.
- Figure 1 shows an insulation glass window . which i double-glazed 2. Both panes of the double-glazed window ar sealed to each other and secured in a window frame 3, 4, 5 6.
- Frame members 4, 6 are especially designed for receivin the Venetian blinds according to the invention.
- Frame member 4, 6 show a C-shaped profile as will appear from Figure 4.
- the Venetian blind consists of thin lamellae 7. At both end of the lamellae 7 T-shaped members 8 are provided with crosspiece 9 and a stem 10 which stem is secured to th lamella end. This may be achieved by riveting, as shown i Figure 2, or in another suitable manner.
- Crosspieces 9 of the T-shaped members 8 engage the thread 1 of threaded spindles .12, 13, which are provided in paralle with frame members 4, 6.
- frame members 4, 6 ar upper and lower frame members.
- Spindles 12, 13 are provide in frame members 4, and 6, respectively, and are supported b elongated arched beds or guides 14, 15.
- Stem 10 of T-shape member 8 extends upwards through a slot a 16.
- Spindles 12, 13 are provided with a left hand thread at the left hand side of Figure 1, and with a right hand thread at the right hand side of the Figure.
- the object of this arrangement is to ensure that the Venetian blind lamellae 7 on the right hand side will be moved towards the middle of the window by the aid of the right hand thread, and that the lamellae 7 on the left hand side of the window in Figure 1 will, simultaneously, be moved towards the midle by the aid of the left hand thread.
- the threaded spindles 12, 13 are, via toothed wheels 17, 18, 19 connected to a driving motor 20. Toothed wheels 17, 18, 19 are mutually engaged in such a manner that both spindles are driven in the same direction.
- Motor 20 is preferably an electrical motor. In a position of use lamellae 7 are provided at a mutual distance which is slightly smaller than the width of a lamella.
- lamellae 7 may be suitable to subject lamellae 7 to a certai tensioning. Space between the panes of a double-glazed windo is most limited, and lamellae 7 should be received betwee the panes. In order to ensure that the packed Venetian blin does not cover too much of the window surface, lamellae 7 must be produced from a very thin material. For such lamella to have sufficient rigidity when a window is mounted horizontally, the lamellae must be subjected to a certain tensioning if they are produced from a very thin material. Tension of the lamellae may be achieved by making crosspieces 9 resilient and clamp them tightly between spindles 12, 13 of both frame memebers.
- Spring tension may also be achieved by designing one or both stems 10 with a hoop-shaped loop 10'.
- two motors 20 and 20' are shown.
- Motor 20 drives spindles 12, 13 at frame member 4
- motor 20' drives spindles 12, 13 at the other frame member 6.
- a common motor may be provided to operate all four spindles by the aid of angular transmissions.
