Window with opening movement parallel to itself

Description

[0001] Window with opening movement parallel to itself The subject of the invention is a window with an opening movement parallel to itself. by means of scissor-like connected opening levers. Such windows, which in the open position are parallel to the frame, are similar to casement windows. Horizontal hinges (skylights) offer the significant advantage that ventilation is considerably stronger and better, whereas in front of windows they are not. Windows with vertical hinges (casement windows) have the advantage that even when the window is fully open, opaque glass can be used. The view out is prevented. On the other hand, the parallel opening position has the advantage over the angled opening position of conventional skylights. The disadvantage is that rain can get into the room.

[0002] To avoid this disadvantage, the window according to the invention is designed such that it can be selectively opened into the inclined position of known hinged window and can be brought into the open position parallel to the frame. For this purpose, according to the invention, the following consist The scissor lever that engages the window consists of two parts, which are articulated together in such a way that when the scissor joint is moved The window opens outwards only at the top, but remains at the bottom against the frame, and after further shifting of the scissor joint by By swiveling out the lower parts, the window comes into the open position parallel to the frame.

[0003] By combining the two opening options according to the invention, it is achieved that the window can be opened in good weather and in bad weather. The weather can be opened, and in bad weather by swinging it into the angled opening position, in which rain cannot get in. In good weather, further opening into a position parallel to the frame ensures good ventilation.

[0004] In known skylights with only an inclined opening position, the opening rods are also sometimes divided into several Parts connected by joints are divided; however, here this design serves only the purpose of initially preventing complete opening, while it The invention does not aim to achieve several stages of an essentially identical type of opening, but rather to enable two completely different openings. different opening types, namely the oblique and the paxallelic.

[0005] Constructively, the two parts of the scissor levers that engage at the bottom of the window can be connected to each other to achieve the desired goal. are connected by a toothed mechanism which only engages after reaching an angled opening position and only then engages the lower parts Parts swing out to achieve the parallel opening position. A similar effect could also be achieved by connecting the two parts using pins of the other part that engage in curved slots of the first part. can be achieved.

[0006] The drawing shows an example embodiment of the window according to the invention.

[0007] Figures i to 4 show the window in side view, with Figure i showing the window in the closed position and Figure 2 in the oblique view. Fig. 3 shows the window in its fully open position. Fig. 4 shows the window folded down; from this position it can be opened for cleaning. can be completely removed from the frame by gently lifting it.

[0008] Fig. 5 shows the left side of the closed window in a front view. Figs. 6 and 7 show the entire window schematically. Illustrative view: closed and open.

[0009] Figures 8 to 14 illustrate details of the opening mechanism on a larger scale, with Figure 8 being a side view of the Connection point of the upper and lower opening levers with the window half open; Fig. 9 shows the same view with the window fully open. Fig. io a horizontal section through one of the window's suspension fittings, Fig. ii a front view of one of the fittings for suspending the window serving lever ends, Fig. 12 a side view of the lever initiating the opening movement, Fig. 13 a side view of the upper and Fig. 14: A side view of the lower locking mechanism.

[0010] The locking bars 2 are attached vertically and slidably to the two vertical longitudinal sides of the window frame i. At the bottom, a The locking rods are hinged to an opening rocker arm 3; at the top, two pivotally connected levers 4 and 5 engage the locking rods. The levers: 5 are firmly connected to the horizontal connecting rod 6: this rod 6 transmits the movement of the one actuated by means of the handle 3. Locking rod onto the other locking rod e.

[0011] At pivot point 7, the lever 18, which causes the window to open and close, is attached to the window frame. With this lever 8 is The upper lever 9, which engages the window, is pivotally connected at pivot point io. The upper swing-out lever ii is pivotally connected to the arms at 12 and The lever 9 is connected via the joint 13. The lower lever 14, which acts on the window, is hinged to this lever ii at pivot point 15.

[0012] On the window, the hanging fittings 16 are located at the top on both sides and the hanging fittings 17 at the bottom. These hanging fittings are U- shaped with an outwardly projecting, rounded web (Fig. 10). In the outer flange of these U-profiles is a slot 18, which during The upper fitting is open on the inside, the lower fitting on the outside. A pin is located at the outer ends of levers 9 and 14. 19 (Fig. ii), on which two grooves 20 and 21 are formed by discs. The slots 18 of the fittings 16 and 17 are closed when the The window pane is hung in the outer grooves 21 of the pins, so that the outer pane 22 of the pins is guided in the U-profile of the fittings 16 and 17. This makes the windows easy to install and remove. The U-shape of fittings 16 and 17 achieves this. that all pins, bolts, etc. are concealed and that there are no outwardly protruding edges or points that could easily damage the curtains. are avoided.

[0013] The lever 8 (Fig. 12) that initiates the window movement has an angled slot 23 with a vertical and an oblique Leg. A pin 24 of the locking rod 2 engages in this slot. When opening, the pin 24 slides first into the slot as the locking rod is pushed upwards. the vertical leg of the slot 23, without exerting any effect on the lever 8. Only when the pin reaches the inclined leg will The lever 8 is pivoted around its pivot point 7, causing the window to open.

[0014] This dead leg of the locking rod movement is now used for locking (when closing) and unlocking (when opening) the window. used. At the top of the locking bar there is a stop 25 (Fig. 13) with a downwardly open slot 26; this slot engages when Closing the window engages the bolt ig of the upper scissor lever 9 in the groove 2o, thereby locking the window. The lower one works in the same way. Stop 27 (Fig. 14) attached to the window frame with the slot 28, into which the bolt i9 of the lower [part] engages when the window is closed. The scissor lever 14 engages with the groove 20. The slots 26 and 28 are not quite vertical, but slightly inclined to the vertical. This ensures This ensures that the window is pressed firmly against the frame when closing (locking) and conversely, when opening (unlocking). The frame is lifted.

[0015] The upper pivot lever 9 is connected to the lower pivot lever 14 by means of a toothed connection (Figs. 8 and 9). This toothed connection is particularly important because they The angled Z-% position of the window is enabled. When the opening lever 8 is swung out from the closed position, the Tooth 29 of lever 1¢ is not engaged with tooth 30 of lever 9; therefore, due to the pivoting movement of lever 8, lever 14 is initially not affected, i.e., the window remains at the bottom of the frame while it is lifted at the top by lever 9. Only when the further Swinging out of the lever 8, tooth 29 engages with tooth 30 (Fig. 8, beginning: the lever 14 begins to rotate around the pivot point 15). and to pivot its lower part outwards, so that the window is also moved outwards at the bottom and from the slanted to the parallel position. Open position reached.

[0016] The outer levers 9 and 14 have a U-profile with an inwardly directed opening; when the window is closed, they lie over the inner levers 8, 11 over, so that the linkage takes up little space and has no protruding edges; in addition, of course the The U-shape strengthens the leverage. The locking rods 2 are either forked or U-shaped in their upper part; this improves the bearing of the The mechanism lever on the locking bar is significantly easier to operate. When the mechanism is folded, the middle levers 8 and ii fold into the free profile space of the locking rod. To further reduce the size of the linkage, the device could be improved by... The locking bar is embedded in the wood of the window frame.

[0017] The window according to the invention can also be advantageously used as an upper or lower window in sliding windows; in this case, the To design windows in such a way that one window can be pushed behind the other when the latter is moved outwards into the open position. was done, so that the two windows were then one behind the other.
