Description

The invention lies in the field of gear mechanisms for tilt and turn windows arranged on the sash or frame. Solohe transmission are known. They drive so-stroke rod assemblies with you which, with the help of locking rollers, striking plates and the like, have a window sash or the like ready to turn or tilt can be brought or locked.

Around a started tilting movement of the sash until it is fully exposed must be continued when using extension arms that are articulated on push rods, gears with a long stroke necessary. Only these make the necessary wide exposition of the window sash with safe forward and backward drive in possible in any exhibition position.

This is where the invention comes in. It solves the task of moving the racks and thus the push rod ends long stroke, because the control handle for the gear for a tilting movement of the wing or the like about its horizontal axis perpendicular to the wing plane below or that pointer rotates around its vertical axis is pivotable and only thereby the movement of the racks or /. of the push rod gear with a long stroke triggered or is initiated.

A preferred embodiment of the gear mechanism for tilt and turn windows is that the gear wheels loosely on a main axis store each with a shell by riveting or the like are firmly connected and the recesses of the shells for Serve recording of the operating handle.

One particularly useful embodiment of the invention is in that stops, which are attached to or in the shells, the insertion of the operating handles into the recesses the bowls easier.

Finally, according to the invention, the operating handle cannot ' be transferred directly from one switching position to another, unless it engages in the rest position.

Fig. 1 shows essential components of the new gear train The hood is pulled apart and arranged one behind the other.

Fig. 4 illustrates in schemes a, b and c the movements, which "take place when the window sash is tilted. The Schemes d and e apply in conjunction with scheme c for turning the window sash.

In detail, FIGS. 1 to 3 show the following structure and the subsequent mode of operation of the transmission. casing and top cap are omitted in the figures for a better overview. .

The rack 1 engages directly in the large gear 2. This is loosely mounted on the main axis 3 in one half of the transmission. The drive of the rack 1 by the gear 2 is used the tilt into te 11 uiig, the readiness to tilt and the further tilting movement up to the end position of the tilting.

The main axis 3 carries another small gear 4 on the gear side in the front in the picture. This is loosely supported. It only käirmt over the twin wheel 5 wit the rack 1.

Fixed to the frame with the large gear 2 is a shell 6 with a Recess 7 for receiving the lower part of the operating handle 8. This lower part of the Grifies Ü is shown in Fig. 1 in flat iron educated. The pinion 4, lying at the front in FIG. 1, is also firmly connected to a shell 9 in which a recess 10 is arranged corresponding to the recess 7. These components have the mutual position clearly shown in FIG. 1 during operation. The operating lever 8 sits loosely on the Hauptaohae 3. All components that are included in Pip. 1 are shown,

are otherwise stored and guided in the usual way in a housing with a cover cap. The rack 1 contains a bore 15 for receiving a driver known in another context! üolzeaö for ctie push rod. As a result of this bolt, the following are grounded: the zoom movements are transferred to the push rods.

It is now essential to the invention that the total thrust of the Häder gear. results from the difference in the thrust movement of the rack 1 from the end position for the rotary movement to the end position of the tilting movement '. The individual turning and shifting movements result from Jt ¹ Xg. 4. The position in Fig. 4a corresponds to the original or rest position for the closed wing or the like. Sole castors or the like on the wing and striking plates on Rahi-ien, which correspond to the usual and therefore not the subject of the invention and therefore not are shown, lock the wing on taps.

The loader drives are shown in Fig. 4 only by the partial circles of the Gears and the partial line of the rack are shown.

If a tilting movement of the sash is to be achieved from position 4a, the operating handle 8 is pivoted (Fir. 1) into the recess 7 of the shell 6. The operating handle 8 is pivoted downward in a known manner perpendicular to the plane of the wing.

The right recess 10 is in the movement described above inevitably moved opposite to the recess 7. "The next movement for the! operating handle 8 is only the Wing provision left. In FIG. 4, the gear position is shown in the tilted position at b and the only transition in scheme c of the operating lever, which leads back to the locking position.

According to the invention, it can only be used in this position. 4a or c be firmly decided on the next form of movement. Therefore, Fig. 4c is the starting position for the initiation of the Rotation movement indicated by arrows.

In this position "fixed" is · like the comparison of the arrow entries in the Mg. b and c shows the recess 10 again in the! Fig. 1 shown! Rest position reset. The recesses 7 and 10 are now facing each other.

Now the operating handle 8 can be placed in the recess 10 of the shell. Is described in the same way, v / ie above, the operating handle 8 is guided / guided downwards perpendicular to the plane of the wing, so the wing assumes its rotational position. That's how it is Rotational position of the wing initiated. Now the wing can be rotated around its vertical bearing axle.

Again, there is no possibility of guiding the operating handle 8 from the rotary position directly into the tilt position, because the recess 7 now moves in opposite directions under the influence of the rack 1 and the gear 2. The recesses 7 and 10 are now no longer opposite one another. This mean one

Hit other words; cann der 13edienun,;, s handle 8 only inevitably transferred to another position via the current G-r and position v / earth. False conditionseii, i.e. a simultaneous turning and tilting, position cannot be carried out.

This preferred inevitable ISeweguiigsrhythiiius of the operating handle ο and thus the I · ¹ lie is facilitated by the guides 12 and 13 in the shells 6 and 9 · The stop 13 in the shell 6 guides the operating handle 8 safely into the recess 7; the stop 12 in the shell 9 inevitably guides the operating handle 8 into the recess 10. The stop 12 is therefore used for the tilted position, the stop 13 for the rotary position.

I take into account that experience has shown that windows are much more common wound as rotated, a helical compression spring is used 14 on the axis 3, the operating handle 8 in the direction to press the recess 7 of the shell 6. For after overcoming The effect of the cooler 14 can be the Jiedienunrsgriff 8 in the recess 10 of the shell 9 is placed around the wing or the like to turn. If in special cases, e.g. in schools, hospitals or the like, one wants to achieve that the window sash or the like is no longer rotatable at all, so that only the tilting movement can be carried out, so can block the recess 10 with a small lock.
