Definitions
- the invention relates to a device for guiding and locking a casement in a window-frame, the device compris- ing pistons which are extendable from and retractable into the casement and arranged at the corner portions of the casement in order to engage in a locked position one groove each of the frame.
- a device as described above is known from Swedish patent application 9703588-5.
- a device in pivot-hung windows is disclosed, which consist of a frame and a casement .
- the frame is on two opposite sides formed with a longitudinal groove.
- the casement is pivoted in a joint mechanism and is in two opposite edge sides provided with a guide bush running in each of the longitudinal grooves .
- the guide bushes are simultaneously, and in pairs, extendable into and retractable from the grooves by means of a turning control. With two of the guide bushes located in one longitudinal groove each, the casement is pivotable half a turn and lockable in the pivoted position by retracting the two free guide bushes and extending the same again to engage one groove each.
- the casement can be pivoted back by once again retracting the last-mentioned two guide bushes from the grooves, or be pivoted further in the same direction by retracting the two other guide bushes from the grooves .
- the turning controls control two spagnolet constructions which are arranged at two opposite sides of the window for extending and retracting the corresponding guide bushes in pairs.
- One disadvantage in this context is that the two controls may be turned by mistake so that all the guide bushes are retracted, which means that the casement may fall out of the frame .
- turning controls are arranged on the casement .
- the handle of the turning controls will be moved to the outside of the window and then has to be detached in order to be mounted once more on the other side of the window.
- the object of the present invention is to provide a device for guiding and locking a casement in a window- frame, which eliminates the risk of the casement falling out of the frame when the device is handled incorrectly.
- This object is achieved by means of a device comprising pistons which are extendable from and retractable into the casement and arranged at the corner portions of the casement in order to engage in a locked position one groove each of the frame.
- the device is characterised in that, when the window is locked, the pistons are in a partly extended position for engaging the frame, and that the pistons which are located on a first casement side are connected to a first link construction, while the which are located on the opposite casement side are connected to a second link construction, and that the two link constructions are arranged adjacent to a turning means for simultaneous motion of the link constructions in opposite directions of motion, said motion causing one pair of opposite pistons to be moved from a partly extended to a completely retracted position, while the other pair of opposite pistons is moved from a partly extended to a completely extended position, or vice versa, for opening and closing the window. Opening and closing of the window thus take place by the two link constructions being moved in opposite directions.
- one pair of pistons is extended into a groove of the frame at the same time as one pair of pistons is retracted from the window frame. It is thus impossible to retract the two pairs of pistons at the same time, and therefore there is no risk that the window falls out of the frame .
- the turning means is actuatable by means of a handle which is arranged in the window-frame. Consequently, also the problem of removing the handle after turning the window is eliminated. Since the handle is mounted in the frame, it is also impossible to actuate the turning means and thus affect the motion of the pistons when the window is open, which gives additional security against the possibility of the supporting pair of pistons being retracted by mistake while the window is open and/or being pivoted.
- the link constructions may advantageously comprise corner links in the form of sectors of a circle.
- the respective corner links of the link constructions are thus mutually concentrically arranged in the corner portions of the casement, so that the link constructions do not prevent one another from moving .
- the device may also comprise at least one locking pin in one of the link constructions, which engages a matching groove of the frame.
- Such locking pins effect guiding of the window when it is to be closed and constitute an additional fixing point which makes the window burglar-proof in a locked position.
- FIG. 1 is a plan view of an embodiment of a device according to the invention
- Fig. 2 is a broken-apart perspective view which illustrates the function of the device in Fig. 1, and
- Fig. 3 is an exploded view of the joining of the corner links of the device in Fig. 1. Description of a Preferred Embodiment
- Fig. 1 is a plan view of the device. The whole structure is surrounded by a frame 1 to be attached to a casement.
- a first link construction 2' is shown in front, which comprises a centre bar 3', an upper corner link 4' and a lower corner link 5' . Furthermore, the link construction comprises an upper pulling bar 6' and a lower pulling bar 7' which are articulated to the respective corner links 4', 5'.
- the corner links 4', 5' are formed as sectors of a circle, and the centre bar 3' and the pulling bars 6', 7' are arranged at the edge of the respective sectors of a circle towards the periphery of the circle. Adjacent to the respective pulling bars, a pulling rod 8', 9' and a piston 10', 11' are arranged.
- the pistons 10', 11' are extendable and retractable through openings in the left side of the frame 1 in Fig. 1.
- the second link construction 2 which is longer than the first construction 2'.
- the second link construction 2 comprises, just like the first one, a centre bar 3, an upper corner link 4 and a lower corner link 5 (not shown in Fig. 1) .
- the corner links 4 and 5 are arranged concentrically with the first corner links 4' and 5', respectively, on a common pivot axis.
- pulling bars 6, 7 are arranged adjacent to the corner links 4, 5.
- An up- per 8 and a lower 9 pulling rod are arranged adjacent to the pulling bars 6, 7, but directed to the right instead of to the left as in the first construction.
- Pistons 10, 11 are, in turn, arranged adjacent to the pulling rods 8, 9.
- the frame 1 is provided with guide means for the pulling rods 8,9 in the form of clamps 12.
- FIG. 2 A part of the device is seen in perspective in Fig. 2.
- the second link construction 2 is here shown above the first link construction 2' . It is evident how the second link construction 2 is arranged behind or above the first link construction 2'.
- the corner links in the respective corners are turnably, concentrically arranged with a fit- ting 13 between them.
- the link constructions 2, 2' may be displaced during turning of the corner links 4, 4' 5, 5' without preventing one another from moving.
- Fig. 3 is an exploded view of the joining of the upper corner links 4, 4'.
- the lower corner links 5, 5' are joined in the same way.
- the central bars 3 , 3 ' are provided with one pair of pulling pins 14, 14' each.
- a turning plate 15 is arranged adjacent to the frame 1 transversely of the centre bars 3, 3' opposite the pair of pulling pins 14, 14'.
- the turning plate 15 is provided with a cylindrical body 16, which is arranged between the two centre bars 3, 3'.
- On each side of the body 16, the turning plate 15 is provided with a transverse pin 17, 17' which is fitted between the respective pairs of pulling pins 14, 14'.
- the turning plate 15 is turnable by means of a closing plate
- the closing plate 18 which is movable back and forth.
- the closing plate 18 is adapted to be operated from a handle (not shown) located ' in the window-frame.
- Fig. 1 shows the device in an open position, where the lower pistons 11, 11' are retracted and the upper pistons 10, 10' are extended.
- the window can then be opened in its lower end and be pivoted about the upper pistons 10, 10' .
- the turning plate 15 is put into anticlockwise motion by means of the closing plate 18, the first transverse pin 17' will put the first centre bar 3' in an upwardly directed motion at the same time as the second transverse pin 17 puts the second bar 3 in a downwardly directed motion.
- the whole second link construction 2 then moves anticlockwise in Fig. 1, the right, up- per piston 10 being retracted and the right, lower piston 11 being extended.
- the first link construction 2' moves clockwise in Fig. 1, the left, upper piston 10' being retracted and the left, lower piston 11' extended.
- Fig. 1 also shows a lower locking pin 19 and an upper locking pin 20, which are arranged adjacent to the lower 9 and the upper pulling rod 8, respectively, of the second link construction 2.
- the locking pins 19, 20 extend through one longitudinal opening each in the frame 1 and are adapted to engage one L-shaped groove each in the window-frame .
- the upper locking pin 20 When, for instance, the upper pair of pistons 10, 10' is retracted, the upper locking pin 20 will be moved to the left. Owing to the L-shape of the groove in the window-frame, the pin 20 may in this position be moved out through the frame so that the window can be opened.
- the pin 20 When the upper pair of pistons 10, 10' is extended, the pin 20 is in its right position and cannot be moved out through its L-shaped groove.
- the locking pins 19, 20 serve as guide means when closing the window.
- the window has in its closed position as many as seven fixing points in the frame, namely the four pistons, the closing plate 18 and the locking pins 19, 20. This makes the window burglar- proof.
- the link construe- tions may enclose the whole casement instead of a part thereof, as in the shown embodiment.
- the link constructions could be made of a non-rigid material, since the links need not exert any pressure.
- the turning plate 15 for regulating the link constructions can be placed in different positions round the casement.
- another advantage of the device according to the present invention is that it may be used on inward- as well as outward-opening windows without changing the construction. Only the placing of the handle on the window-frame will be changed. In both outward- and inward-opening alternatives, opening and pivoting of the window may take place in the lower edge or the upper edge in accordance with the user's wishes.
- the device according to the present invention is particularly advantageous in combination with pivot-hung windows, but is also useful in, for instance, conventional windows as it results in a burglar-proof window lock. This is especially the case if locking pins are ar- ranged in the link constructions.
- the handle for operating the closing plate 18 may be provided with a blocking device, which blocks the handle in a locked position as the window is being closed, i.e. all the pistons are equally extended.
- the blocking device is released by, for instance, being pressed and the handle is turned for opening in one or the other opening direction.
