"Control device for a fitting for window αηά

Door leaf "

The invention relates to an operating device for a Fitting for window and door sashes or the like with an operating lever that can be rotated and tilted at the same time, its adjusting arm an adjusting rod for adjusting the wing to the readiness for two different movements of the wing conveyed. Here z. B. by turning or pulling the control lever a setting to turn or tilt readiness of the wing. According to an earlier, not pre-published Proposal, is to close the control arm that moves the control rod in the vertical direction. for this purpose the side facing away from the operating lever is provided with a ball head and bent in a Z-shape so that when turning of the operating lever around its axis, the ball head performs a vertical adjusting movement in addition to the rotary movement, which is opposite for adjusting movement when tilting the operating lever around the axis. Such a curved arm-shaped one However, the actuating arm is often difficult to accommodate within the frame.

The invention aims at a design that especially cheaper accommodation within the railroad With adequate means and reliable intervention of the parts that transmit the movement and essentially consists in the fact that the actuating arm carries a gearwheel, which is mounted in a parallel or approximately parallel to the control rod sliding bearing member and with a the adjusting rod arranged toothing meshes such that an adjustment is made by turning or pulling the operating lever on the willingness to. one of the two types of movement of the I-wing takes place.

The arrangement is hereby made in a way that that when you turn the operating lever about its axis of rotation perpendicular to the first plane, the gear has a rotating one Adjusting movement aasführung, with this via the meshing with the gear toothing of the control rod is pushed in one direction, while pulling the operating lever around the parallel to the lenster plane lying tilt axis the gear is taken by the actuating arm, in particular in such a way that the actuating rod in the direction opposite to the first actuating direction is pushed. In the former case, this is the gear on see operated while in the second! "all the gear with the control rod is moved as a unit by the operating lever.

In a preferred embodiment of the invention encloses serving as a bearing for the gear bearing member

Gehäaseartig the gear and the one provided with the toothing Section of the control rod.

Such an embodiment has the advantage of being particularly simple Assemble with safe operation of the actuating linkage, in order to be carried along safely with kinematically favorable intervention of the gear through the operating lever in the direction of the control rod and at the same time a reliable backup To ensure the gear against rotating with respect to the actuating arm of the operating lever, the gear also has a centrally arranged, roughly rectangular or similarly shaped Recess, in which the cross-section is also approximately rectangular or corresponding and preferably in longitudinal section engages spherically shaped head of the adjusting frame.

Further details of the invention are as follows Refer to the description of an exemplary embodiment. Here show:

Fig. 1 is a vertical section through the actuating device, in section according to Line 1-1 in FIG. 2, FIG. 2 shows a vertical section perpendicular thereto according to line 2-2 in d-he Fig. 1 and

Fig. 5 is a horizontal section along the line 3-3 in Fig. 1.

In the drawing, the fixed frame 120 and the casement frame 121 are composed of profile iron! but the frame can also be designed as a wooden frame or in some other way. The bearing piece 142 is fastened to the casement 121 by means of screws 145. In the bearing piece 142, a bearing bush 145 is rotatably mounted about the axis Sn ″ ^{x p.}

The bearing bushing has a rectangular opening into which the middle bearing part 147 of the designed with a corresponding cross section with it. an operating lever 139 firmly connected handle 139a protrudes. The lever 139 with the bearing part 147 is pivotably mounted in the bearing sleeve 145 by a transverse bolt 148 so that it can be pivoted about the horizontal axis x-, -x ,, running parallel to the frame plane. With the bearing part 147 an in the axis Xp-X _{2 of} the rotatable bearing sleeve 145 into the interior of the cavity formed by the frame 120,121 protruding actuating arm 149 is firmly connected, with its rounded end 150 with a rectangular cross-section in a rectangular recess 160 a Gear 161 engages. The latter is rotatably mounted in bores 162 of a housing-like bearing member 163, the axis of rotation of the gear in the illustrated position of the device coinciding with the axis of rotation Xp-X ₂ (^ ^z w. X _? ). The gear 161 is in engagement with a rack 164 * which is slidably guided in the housing-like bearing member 163 and is fixedly connected in a suitable manner to the bending rod, of which the rack can form a part.

In the position of the gate direction shown, this is in the closed position of the wing .. If the hill is to be set to tilt about a horizontal axis ready to tilt, the handle 139a is pivoted in the direction of arrow z ^ about the transverse axis x ^ -xi, whereby the actuating arm 149 reaches position 149 ^1. As a result, the gear 161 is moved downwards in the direction of arrow y

serving as a bearing link of the ZahnHtaijgec

housing-like Mitnähmet part 163 and the rack 164 as a unit on the hub h * with. If necessary, the movement of the actuating linkage 132 in the direction of 3T ₁ can also be carried out at the same time following the conversion of the hill. X-readiness to tilt the same by actuating a suitable opening device.

If the! Wing is to be pivoted about a vertical axis, the lever 139 is turned in the direction of rotation z _? (! Pig. 2) rotated, which results in a corresponding rotation of the gear 161, which remains pushed in the process. The toothed rack 164 with the actuating rod 132 is thereby moved upward in the direction of the arrow yv> j, for example by the stroke ho, with the itager member 163 remaining in its central position. As a result *, the I ¹ IUgel is locked in its vertical pivot axis, while it is unlocked in its horizontal zip axis * The wing can then be pivoted around the vertical axis by pulling the handle 139a,

So that the operating lever, when it is pivoted about the transverse axis x *, cannot be rotated simultaneously about the longitudinal axis Xp or, conversely, when it is rotated about the longitudinal axis Xp, it cannot be rotated simultaneously about the transverse axis x. can be pivoted, are special Terriegelungsvorriohtungen, z. B,! Claws 158 on the bearing piece 143 and 156 on the operating lever 139 'are provided, which lock against one another in one sense or the other.
