Window handle

The innovation concerns a window handle for one-handed operation, Especially for tilt and turn windows, consisting of handle and olive, in the coaxial attachment of the square is held for the lock actuation, and from a fitting to be fastened to the window, the rosette'bearing fitting, with respect to which the olive is axially fixed but rotatable.

In these known window handles, the individual Positions achieved by bringing the window handle into an approximately horizontal or vertical position, in which case the release of the lock usually only takes place after a slight correction of the rough adjustment made is achieved. It is also desirable that the window handle is perfectly horizontal or vertical to the Fender frame is aligned.

The task on which the innovation is based is therefore to precisely fix the individual setting positions.

Starting from a window handle of the type mentioned, this task is carried out on the rosette on the locking side recesses provided at a fixed angular distance and by a non-rotatable seat on the attachment, Latching plate pressed elastically against the rosette with protuberances for latching engagement in the recesses released.

The rosette with the recesses together with the fitting is expediently made of plastic Piece trained.

A good engagement and release of the locking engagement is achieved when the recesses are semicircular and the protuberances are designed accordingly. The locking plate is pressed against the rosette by a wave spring, which is fixed on the closure side by a spring ring held on the shoulder. This also has the advantage that the olive does not lift off the rosette when turning.

The locking plate has two inwardly facing tongues that protrude into the clamping slot of the neck receiving the square. This is the locking plate with respect to the approach held non-rotatably in a simple manner.

The recesses in the rosette and the protuberances in the locking plate are advantageously each other offset by 9o ° so that the window handle has four locking positions. When doing the angle between the tongues and the protuberances of the locking plate is 45 ° and the center plane of the clamping slot of the approach to that of the Handle lever is offset by 9o °, you get four locking positions, with the elongated in two of these locking positions trained fitting with its center plane parallel to the handle lever and perpendicular in the other two locking positions to this lies.

The tongues can have a game with respect to the clamping slot, so that the handle lever has a small dead gear corresponding to this game.

The window handle according to the innovation has the advantage that the locking positions and thus the associated lock positions of the window closure are precisely fixed, this fixing being noticeable by snapping into the locking position and by the resistance when pushing out of the locking position and, if necessary, the snapping can also be detected acoustically.

The innovation is explained in more detail using the accompanying drawing, for example.

Fig. 1 shows an embodiment of a window handle according to the innovation pulled apart.

FIG. 2 shows, in a side view, a detail of the window handle from FIG. 1, enlarged.

Fig. 3 shows a plan view of the inner face of the rosette.

Fig. 4 is a top plan view of the locking plate.

The window handle shown in Figures 1 to 4 consists of a handle lever 1. and which is at right angles adjoining olive 2. The olive 2 has a coaxial extension 3 of smaller diameter with a Clamping slot 5, the central plane of which extends perpendicular to the central plane of the handle lever 1. In the area The extension 3 has a circumferential groove 6 at its free end.

j; The fitting 7 to be attached to the window consists of

a substantially elongated rectangular plastic piece molded in one piece with one in the middle Rosette 9 which encloses a central opening 11. The fitting 7 has, in relation to the rosette 9, diametrically opposite each other a hole 1o for fastening of the fitting 7 on the window. The central opening 11 of the rosette 9 widens to an opening 12, so that the inside of the rosette 9, d. H. the window frame or Window closure opposite end face, designed as a shoulder. In this end face are in each case by 9c ° Semicircular recesses 13 offset from one another are provided, the recesses in FIG. 1 for better illustration

13 are shown offset by a total of 45 °. The fitting 7 is surrounded on its side opposite the handle part 1 by a metal cover 8 which has a central opening whose diameter corresponds approximately to the outer diameter of the rosette.

In the assembled state, the square 4 provided for operating the lock is in a recess in the approach 3 and the olive 2 inserted non-rotatably over the shaft 4 a locking plate 14 is pressed against the inside of the rosette 9. The locking plate 14, which is shown in detail in Fig. is shown, has two diametrically opposite, inwardly projecting tongues 15, which with a little play engage in the clamping slot 5, whereby the locking plate

14 is non-rotatable with respect to the olive 2. At a 45 ° distance from the center plane of the tongues 15 are on the locking plate 14 Protrusions 16 are provided. These protuberances are in the snap-in positions with the recesses 13 in the rosette 9 ir engagement, whereby the individual recesses 13 from FIG. 3 are closed are seen. The locking plate 14 is in the Einraatlayen

· 5

held by a wave spring 17, which by means of a washer 18 and a spring ring 19, which is in the Groove 6 is introduced in the approach 3, presses against the locking plate 14. The locking position of the individual elements is shown enlarged in FIG.

When removing from. this locking position a resistance must be overcome, since the protuberances 16 when twisting move the olive 2 out of the recesses 13, whereby the locking plate 14 axially in the direction of the window moved and the wave spring is compressed. The so tensioned wave spring 17 results in A clearly noticeable snap-in when the next detent position is reached. Due to the tensioning effect of the wave spring 17 the olive 2 is always pressed against the rosette 9, d. H. there is no axial play.
