AUG. HÖRSTER in VOHWINKEL.

The invention relates to a skylight closure with a locking device attached to the window sash, on which - attacks a pull cord causing the window to open and close.

The essence of the invention is that a lever without special tools, like springs and the like, solely due to its peculiar design and storage, i.e. H. laying its center of gravity, both for releasing the window in the closed position holding closure means, as well as for pushing the window sash out of the Locked position and also as an attack for the pull cord when closing the window Application comes.

Compared to the previously known skylight window closures, the subject of the invention the advantage of the utmost simplicity, "since the opening and closing of the skylight window serving means are limited to the smallest number, while those known Closures more or less a union of different levers, handlebars and springs are present.

In the drawing, the subject matter of the invention is illustrated, for example, and although shows:

Fig. Ι a front view, the window closed, the lever is about to open the window,

Fig. 2 is a side view of the lever in same position as in Fig. 1,

3 shows a side view with the lever position changed and the locking means released,

4 shows a side view with the lever position changed again, the window sash from the closed position pressed,

Fig. 5 is a side view, the window about to close,

Fig. 6 is a top view of Fig. 4, the 'window open and

FIG. 7 shows a top view of FIG. 5.

In the drawing, 1 is the window frame on which the window sash 2 is known Way is arranged foldable down. A drop hook hinged on the window frame 3 is opposite a provided on the window sash nose 4 and can as a result of his Slide the bevel on the front hook part over the nose and catch yourself so that the window sash by the drop hook in a known manner in the closed position is held (Figs. 1 and 2).

In a cut in Fig. 1 to 5 shown housing 5 on the window sash, a curved lever with an approximately horizontal arm 6 in the closed position with an approximately vertically bent leg 7 is ^{mounted on a pin 8 in a suitable housing 8 a} , which is laterally in a half-ring groove 9 of the leg 7, which is semicircular below, engages. This storage is so loose that the lever can not only rotate freely, but can also tilt in all directions. Will the lever go so far

Claims (3)

turned around so that the pin 8 emerges from the groove 9, its storage is released and it can be removed from the housing. An inclined shoulder 10 is provided on the leg 7 which steps under the bevel of the drop hook 3 when the lever is rotated when the window is in the closed position by pulling a line 12 which engages it and is guided over rollers 11. The shoulder lifts the halyard hook and thereby brings it out of engagement with the nose 4 (FIG. 4). When turning the lever further, he braces himself against the window frame (Fig. 4) and pushes the window sash out of its closed position, whereupon, after loosening the cord, the window sash continues to open due to its weight until it is prevented from moving further by any stop. ao On the upper part of the leg 7, a nose 13 is arranged, which comes to stand opposite a recess 14 provided on the housing (position α in FIG. 7) when the lever with the window open, following its gravity, is perpendicular to the. Adjusts the sash. If the line is pulled to close the window (Fig. 7), the lever tilts in the direction of pull of the line in its storage. in such a way that the nose 13 enters the recess 14 and thus secures the lever against rotation (position b in FIG. 7). By further tightening the leash, the window sash is brought into the closed position, the drop hook 3 catches itself over the nose 4 and keeps the window closed. The lever, which is held in a locked position against rotation until the window is completely closed by the pull on the line, tips over at the front when the line is suddenly released and its nose 13 emerges from the recess 14. This unlocks the lever again and when the leash is pulled it can repeat the movements necessary to open the window. Pat ε ν τ claims: 1. Skylight window lock with a locking device attached to the window sash, on which a pull cord which effects the opening and closing of the window engages, characterized in that that a lever provided with an oblique shoulder is rotatably and tiltably mounted in a housing on the window sash is that when pulling the pulling means that is acting on him to open the window, he uses his shoulder the known drop hook holding the window in the closed position triggers and then, bracing against the window frame, the window sash brings from the closed position, while in the open position of the window, the lever adjusts itself so that it when pulling the traction mechanism tilts and comes into engagement with a locking member, which is a turning of the lever prevented during closing and after tilting the released lever after the window has been closed releases the lever again. 2. Skylight window closure according to claim I, characterized in that the curved lever (6, 7) is provided on its leg (7) with a half-ring groove (9) into which a pin located ^{in a bearing "housing (8 fl)"} 8) engages laterally in such a way that the lever can be removed from its storage or replaced when the lever has been rotated so far that the groove has emerged from the area of the pin. 3. Skylight window closure according to claim I, characterized in that the locking of the lever by a nose attached to it (13), which when Tilting the lever while closing the window in one on the window sash or on a part of it provided recess (14) occurs, is effected. 1 sheet of drawings.
