Description
1 23871 99
A fitting for sashes in windows or the like The invention relates to a fitting for sashes in windows, doors or the like, which can be tilted or pivoted 180 inwards or outwards, with the features set forth in the introduction to claim 1.
5 Various embodiments of such fittings are known. The British patent application 20 25 499 (NO 141 958) discloses a fitting by means of which a supporting arm is hinged immovably to the sash and movably to the blind frame, and where a guide arm is provided which at both ends is hinged immovably on one side to the supporting arm and on the other side to a fixing 10 plate that can be securely screwed to the blind frame. For the movable axis of rotation and for the movable hinge point on the supporting arm, in the rebate of the blind frame there is mounted a common guide rail with different guide sections for the different sliding pieces.
In another embodiment (see DE-OS 21 25 639 and NO 122 614), the 15 supporting arm, which at one end is immovably hinged to the sash frame supported by two immovable, hinged and approximately parallel load and guide arms, which are spaced at a distance apart, and whose sides are rotatably mounted immovably on a securing plate, which can be screwed on to the inside of the blind frame. The device is so designed that in the sash's 20 closed position all the arms of the scissors thereby formed on the side will be aligned from their hinge points on the frame side in the direction towards the axis of rotation at the upper end of the sash.
These and other known fittings of this kind can be employed in outwardly pivotable sashes with the axis of rotation located on the upper sash edge or in 25 inwardly pivotable sashes with the axis of rotation located on the lower sash edge. All of these fittings have one or more serious drawbacks. In one case, only a relatively slight change in the height of the sash is needed before another fitting size is required, with the result that a large number of fitting sizes have to be stocked in order to cover the entire possible range of heights.
This requirement is ascribed to the simultaneous requirement for supporting each sash regardless of the height as close as possible to the middle of the height by means of the supporting arm in order thereby to achieve the best possible counterpoise. In the first place, correctly balanced sashes will not be 5 more difficult to operate. Secondly, when rotated about 180 , the lower end of the sash will project noticeably beyond the upper end of the blind frame.
A further serious disadvantage of one of the known types of fitting consists in the fact that the two scissors on the side each have to be incorporated in a recess on the side of the blind frame. The incorporation of such recesses is 10 extremely difficult to accomplish with plastic or light metal frames and is also complicated with wooden frames. Moreover, there is a total lack of covering for the scissors externally, which in the case of swivel windows that are opened outwards leaves them totally exposed to the weather. Furthermore, the large recesses in the frame also affect the sealing capability of the window 15 sash. Such a device is necessary since in order for this known fitting to be able to be pivoted over the large angle of 180 , during its movement from the closed position to the 180 position, the sash will pass all parts of the scissors, including the supporting arm.
In NO 178043 a fitting is described, which to a great extent avoids the above 20 mentioned disadvantages. The fitting comprises a scissors device with supporting arm, which in the sash's closed position is located on the half of the sash facing away from the sash's axis of tilt or rotation. The disadvantage of this fitting is that in the window's open position, the supporting arm and the scissors device can easily be exposed to impact, etc. or be in the way, 25 which may lead to warping of the fitting, resulting in it having to be replaced.
The task that forms the basis for the invention is to avoid the aforementioned disadvantages and to further develop a fitting where, on the one hand the entire height range of the sash can be reliably covered with only a few fittings of different sizes, while at the same time still providing a sash which also has
good counterpoise at varying heights, as described in the introduction to
claim 1. The object of the further development is to achieve a fitting with the said advantages, while shielding the scissors from impact, etc. when opening the window and at the same time achieving a fitting that provides stable 5 movement of the window. A further object is to provide a compact fitting, i.e. a fitting that requires little space.
This task is solved by means of the features indicated in the following patent claims. In an embodiment of a fitting according to the invention, no recesses are 10 required on the side of the blind frame for insertion of scissors in the frame.
The attachment of a fitting according to the invention requires only a small groove in the flange of the sash. This is because the fitting is compact and requires little space. This characteristic also permits the fitting to be used in plastic window frames.
15 From the manufacturing point of view, the fitting may be prefabricated, since the two guide and support hinges for each scissors are advantageously securely hinged to a mounting bracket. The fitting may be connected to a guide rail for the sash's axis or rotation or it may be a separate part. For mounting at a predetermined window height, it is only necessary to shorten 20 the guide rail to the height of the sash, and this shortening process may be carried out to an equal extent from both ends of the guide rail, thus ensuring that when using one and the same fitting with sashes of different heights, the sash is at all times securely supported approximately in the middle of its height by means of the supporting arm and will therefore be counterpoised.
25 The fittings can be mounted extremely easily and quickly. The fitting may be used both for outwardly pivotable sashes as well as for inwardly pivotable sashes. The invention will now be described in greater detail by means of schematic drawings illustrating an embodiment, in which:
Figs. 1-2 are a perspective view of a pivotable sash with a fitting according to the invention, where the sash in the two figures is illustrated in different opening and pivoting positions.
Fig. 3 is a side view of the fitting according to the invention, where the sash 5 is basically located in a closed position.
Fig. 1 illustrates a blind frame 1 with a sash 2 where the sash is in a slightly opened position. In the blind frame 1 there is inserted a profiled guide rail 8.
This has an open guide groove for guiding the sash's 2 axis of rotation 4b in the known manner. In the illustrated example the sash 2 is in the form of a 10 pivotable sash or pivotable window sash. It has a sash flange 3 with a predetermined width. In the case of the pivotable sash 2 the horizontal axis of rotation for the sash is located in the area of the upper end 4 of the sash. This axis of rotation is composed, e.g., of pivots on the side, which engage with the guide groove in the guide rails 8. The axis of rotation 4a is therefore 15 movable along the height of the window opening, in the guide rails 8, as indicated by a double arrow.
For supporting and guiding the sash in its movement, a fitting with scissors 10 is mounted on both sides of the sash. Each scissors 10 consists of a supporting arm 11, which based on the sash height is hinged immovably 20 approximately at the middle of the sash at fulcrum 18. To the other end of the supporting arm 11 and at a distance therefrom, two load and guide arms 12 and 13 are immovably hinged, which in turn are immovably hinged at their other end to the blind frame 1 on one side of the guide rails 8.
From figs. 1-2 it is apparent that all the load and guide arms 12, 13 in the 25 scissors 10 extend between their attachment points in the supporting arm (14 and 17 respectively) and the respective related fulcrums in the blind frame (15 and 16 respectively). A first guide and load arm 12 is attached at a fulcrum 14 to the supporting arm 11. A second guide and load arm 13 is attached at a fulcrum 17 to the supporting arm 11. The fulcrum 17 between the second
guide and load arm 13 and the supporting arm 11 is located at a greater distance from the fulcrum 18 between the supporting arm 11 and the sash 2 than the fulcrum 14 between the first guide and load arm 12 and the supporting arm 11.
5 The fulcrum 18 between the supporting arm and the sash and the fulcrum 17 between the supporting arm 1 1 and the second guide and load arm 13 form a line. The third fulcrum on the supporting arm, the fulcrum 14 between the supporting arm 11 and the first guide and load arm 12 are located at a distance from this said line, and located on the side of the line, which when 10 the window is almost closed, is facing the blind frame 1. In other words, in the closed position of the sash the distance of the fulcrum 14 from the guide rail 8 is less than that of the fulcrums 17 and 18.
The first and second guide and load arms, 12 and 13 respectively, are pivotably, immovably attached to the blind frame 1. The first guide and load 15 arm 12 is attached to the blind frame 1 at a fulcrum 15 and the second guide and load arm 13 is attached to the blind frame 1 at a fulcrum 16. These fulcrums 15, 16 form a second line that forms an angle with the guide rail 8.
The second guide and load arm 13 has at least two angled portions. In a preferred embodiment as illustrated in the figures, the second guide and load 20 arm has three angled portions (31,32,33). When the window is in a closed position from the attachment point 17, the arm 13 comprises a first vertical portion, an angled portion 31, with the result that the arm extends at an angle to the guide rail 8, thereafter a new angled portion 32, with the result that the supporting arm again extends vertically, with an additional angled portion 33, 25 with the result that the arm extends at an angle from the guide rail 8. The first guide and load arm 12 has a curved groove 30 on the side facing the second arm 13. This groove makes room for one angled portion that comprises the fulcrum between the second arm and the blind frame when the sash is in a closed position.
In the closed position of the sash, the load and guide arms 12 and 13 are located substantially behind each other. Along one side facing away from the load and guide arm 12, 13, the supporting arm 11 has a longitudinal flange.
On the other hand, in the closed position of the sash, the supporting arm 11 is S located beside the two guide and load arms 12 and 13. The length of the supporting arm's flange is such that it covers the outside of the load and guide arms 12, 13.
The fitting according to the invention comprising the supporting arm 11 and the load and guide arm 12, 13 may be affixed to a mounting bracket 40. The 10 mounting bracket 40 may be a part of, attachable to or separate from the guide rail 8. Where the mounting bracket is separate from the guide rail 8, the fitting with supporting arm 1 1 and load and guide arm 12, 13 can be replaced without the guide rail 8 having to be dismantled and/or replaced and vice versa. If the fitting is to be used for sashes of a lower height, the rail 8 is 15 merely shortened correspondingly from both sides and approximately the same amount. Nothing is therefore altered regarding the relative positions of the scissors 10 and the blind frame 1 and the relative positions of the fulcrum 18 and the sash 2, with the result that all sashes regardless of their height can be supported approximately in the middle and counterpoised by means of the 20 fitting. In a preferred embodiment, but not illustrated in the figure, the fitting comprises a lock device for locking the window in a ventilating position. For this purpose, to the end portion of the supporting arm 11 affixed to the sash 2 a locking dog bracket is mounted, which interacts with a pin mounted in the 25 blind frame. The locking dog bracket is rotatably attached to the supporting arm, and may also be spring loaded, where the spring loading attempts to keep the locking dog bracket engaged with the pin in the blind frame until it is actively moved out of engagement with the pin while the window is moved further outwards. This provides a child safety device for opening the window.
A further feature of the invention is that the fulcrum 18 between the supporting arm 11 and the sash 2 is placed as close as possible to the supporting arm's 11 longitudinal flange. When the sash 2 is in a closed position, the outside of the supporting arm's longitudinal flange is aligned 5 with the outside of the sash's sash flange 3. By placing the fulcrum 18 in this manner between the supporting arm l l and the sash 2, the smallest possible groove is required in the sash's sash flange 3 in which to place the scissors 10. The fitting for the window is described in the above with references to an 10 embodiment. Other alternative embodiments may be envisaged within the scope of the invention as it is defined in the following claims.
