Definitions
- This invention relates to a bottom-hung window unit, in particular a bottom-hung window unit whose frame is made of metal, PVC or similar materials, wood - PVC, etc.
- bottom-hung windows are used extensively because they meet a wide range of requirements in buildings of all kinds (residential, schools, hospitals, factories and so on).
- Windows of this kind are installed in the parts of a building that are not easy to reach as, for example, is the case of transom windows or fanlights (usually above a door) or that are situated very high up (as, for example, in factory buildings) and are opened preferably using a suitable operator or other tool with hooking means at its top end.
- a window of this kind has two hinge points between the mobile frame and the fixed frame on the bottom horizontal edge and a single point by which the mobile frame is closed, on the top horizontal edge.
- the single closing point which is usually located half way along the width of the window frame, consists of a well known device which those familiar with the trade refer to as "latch".
- the latch is basically a fastening element, consisting of a pin mounted on suitable supporting means (plates) attached to the mobile frame, and a striker element attached to the fixed frame.
- the striker element (usually an inclined surface) is normally coaxial with the latch pin which can slide axially (in both directions, thanks to a spring) towards an engagement slot located at the innermost end of the striker element.
- the outermost end of the latch has a ring handle that can be operated by hand or engaged by a hook or operator.
- the user can release the latch pin from the engagement slot so that gravity causes the mobile frame to be tilted towards the inside of the room where it is installed.
- the user pushes the mobile frame towards the fixed frame until the pin springs into the slot.
- the single closing point makes it difficult to close the window satisfactorily because, amongst other things, windows of this kind usually have irregular proportions (very wide and low, very narrow and tall, depending on requirements) and thus the single closing point, which is usually positioned, as mentioned above, half way along the window, cannot provide an efficient seal or sufficient guarantee of security for the entire window.
- the single closing point offers little resistance to would-be burglars and applies insufficient pressure on the weather strips, especially at the corners furthest away from it, providing an ineffective seal against rain and/or draughts (as well as low insulation against noise).
- the aim of this invention is to overcome the above mentioned disadvantages by providing an operating device for opening and closing bottom-hung windows which is extremely versatile and can be mounted on bottom-hung windows of any kind and size and which offers a high level of security, an effective weather seal and ease of operation when opening and closing the window.
- the window unit according to the invention is of the bottom-hung type.
- This type of window unit basically comprises a mobile frame 2 and a fixed frame 3 hinged to each other, at 3i, by a pair of customary hinge bodies, along a respective first crosspiece 4 and drive means 5 for opening and closing the window unit 1.
- the mobile frame 2 and the fixed frame 3 each have respective longitudinal grooves C2 and C3 in which operating accessories can be fastened.
- the drive means 5 act between a second crosspiece 6a and 6b, parallel and opposite the first crosspiece 4 on which the mobile frame 2 is hinged to the fixed frame 3.
- the drive means 5 enable the window to be moved between an open configuration, where the second crosspiece 6a of the mobile frame 2 is away from the respective second crosspiece 6b of the fixed frame 3 (that is to say, where the mobile frame is tilted towards the inside of the room relative to the fixed frame 3) and a closed configuration where the mobile crosspiece 6a is in contact with the fixed crosspiece 6b (see arrow F2, Figure 2).
- the open position at a predetermined angle is attained by a stay rod, labelled 2t and not described in further detail because it is of well known type.
- the drive means 5 at least comprise operating means 7 located on the mobile crosspiece 6a and having at least two elements 8 and 9 for closing the mobile frame 2 against the fixed frame 3.
- the closing elements 8 and 9 are spaced far apart one from the other and can be securely coupled to respective strikers 10a and 10b located on the crosspiece 6b of the fixed frame 3.
- means 11 are provided to act on the operating means 7 to actuate the mobile frame 2 in such a way that the window 1 is moved automatically from the open to the closed configuration.
- the aforementioned closing elements 8 and 9 are preferably, but not necessarily, equally spaced from a central point on the mobile crosspiece 6a.
- the two closing elements 8 and 9 may be positioned in the vicinity of the respective corner zones of the mobile crosspiece 6a.
- the drive means 5 further comprise an actuating element 12 located on the outside of the mobile crosspiece 6a and acting on the operating means 7 in such a way as to enable the operating means 7 at least to switch from the closed to the open configuration.
- the actuating element consists of a lever or handle 12 that rotates about an axis perpendicular to the plane of the mobile frame and associated with a spindle 15 housed in a respective covering element 16 associated with the outside of the mobile crosspiece 6a.
- the spindle 15 has a radially protruding pin 17 that engages a recess 18 made in a first operating portion 19a of a slider 19 for moving a drive rod 7a located in the mobile crosspiece 6a.
- a second operating portion 19b of the slider 19 extends into the mobile crosspiece 6a through a slot 20 made in the mobile crosspiece 6a itself; in use, the second, internal operating portion 19b is interposed between two contact elements or bosses 21 and 22 located on the rod 7a (see Figure 6) and in such a way as to enable the rod 7a itself to be actuated in both directions, corresponding to the closed and open configurations of the mobile frame 2 (see arrows F7a).
- the operating means 7 comprise the aforementioned drive rod 7a, which is slidably accommodated in the groove C2 in the mobile crosspiece 6a.
- the drive rod 7a is associated with vertically protruding bosses 8 and 9 constituting the aforementioned closing elements.
- the aforementioned automatic switch means 11 comprise return means 13 and cam means 14 located in the vicinity of the two strikers 10a and 10b.

Description
- This invention relates to a bottom-hung window unit, in particular a bottom-hung window unit whose frame is made of metal, PVC or similar materials, wood - PVC, etc.
- At present, bottom-hung windows are used extensively because they meet a wide range of requirements in buildings of all kinds (residential, schools, hospitals, factories and so on).
- Windows of this kind are installed in the parts of a building that are not easy to reach as, for example, is the case of transom windows or fanlights (usually above a door) or that are situated very high up (as, for example, in factory buildings) and are opened preferably using a suitable operator or other tool with hooking means at its top end.
- Typically, a window of this kind has two hinge points between the mobile frame and the fixed frame on the bottom horizontal edge and a single point by which the mobile frame is closed, on the top horizontal edge.
- The single closing point, which is usually located half way along the width of the window frame, consists of a well known device which those familiar with the trade refer to as "latch".
- The latch is basically a fastening element, consisting of a pin mounted on suitable supporting means (plates) attached to the mobile frame, and a striker element attached to the fixed frame. The striker element (usually an inclined surface) is normally coaxial with the latch pin which can slide axially (in both directions, thanks to a spring) towards an engagement slot located at the innermost end of the striker element. The outermost end of the latch has a ring handle that can be operated by hand or engaged by a hook or operator.
- With this device, the user can release the latch pin from the engagement slot so that gravity causes the mobile frame to be tilted towards the inside of the room where it is installed. To close the window, the user pushes the mobile frame towards the fixed frame until the pin springs into the slot.
- Although this type of window is widely used, its structure presents several problems that are as yet unsolved.
- The main drawback of this type of window is, indeed, the closing device at a single point.
- The single closing point makes it difficult to close the window satisfactorily because, amongst other things, windows of this kind usually have irregular proportions (very wide and low, very narrow and tall, depending on requirements) and thus the single closing point, which is usually positioned, as mentioned above, half way along the window, cannot provide an efficient seal or sufficient guarantee of security for the entire window.
- In particular, the single closing point offers little resistance to would-be burglars and applies insufficient pressure on the weather strips, especially at the corners furthest away from it, providing an ineffective seal against rain and/or draughts (as well as low insulation against noise). The aim of this invention is to overcome the above mentioned disadvantages by providing an operating device for opening and closing bottom-hung windows which is extremely versatile and can be mounted on bottom-hung windows of any kind and size and which offers a high level of security, an effective weather seal and ease of operation when opening and closing the window.
