IMPERIAL

PATENT OFFICE.

The invention relates to a skylight closure with a wire rope guided in tubes o. The like. As a means of movement for the window sash.

The essence of the invention is that the wire rope at its upper end with a peculiar device is connected, through which the window sash is both pressed when closing and locked as well as when opening ίο unlocked and also pushed off the window frame will.

The subject matter of the invention is illustrated in the drawing, and it shows

Fig. Ι the whether the closure is seen from the side with the window sash closed,

Fig. 2 the same seen from above with the window sash open,

Fig. 3 is a plan view with the window sash closed.

The guide body δ for the tubes with the wire rope c is attached to the window frame α. The latter is connected in a suitable manner and expediently movably to the locking hook d , which in turn sits rotatably about pin d ³ on the support e attached to the upper frame leg of the skylight window f.

The guide body δ carries a fixed one

Arm δ ¹ , at the front end of which the fixed locking pin δ ^{2 is} arranged, which can be provided with a roller for the purpose of easy movement.

When the window is closed (FIG. 3), the locking hook d has encompassed the pin δ ² , and thus the closure is effected.

If the wire rope c is now shifted in the direction of the arrow, the bolt d connected to it is first rotated so far that the bolt pin δ ^{2 is} free (Fig. 2), with the bolt slot d ^{1 gradually moving away from the axis of rotation} at the same time the window sash is pushed out of the frame and opened further as the traction mechanism is moved further.

So that the bolt d retains the open position after the window is opened and cannot return to a position prematurely when the window is closed that would prevent reclosing, a lock g is arranged in the carrier e, which with. the pin m present at its front end snaps into the hole d ² provided in the bolt d and coinciding with this pin and thus holds the bolt in place. Since the lock g bears an elevation near its front end, against which the locking ^{pin δ 2} abuts during the closing movement and thereby brings the locking pin out of engagement with the bolt, this can turn inward again and encompasses the slot d ¹ again Locking pin to tighten and lock the window sash when you turn it further. The lock g can be influenced by a spring which constantly pushes the piece carrying the locking pin upwards; However, this is not necessary, because the lock can also be designed so that it remains in the position in which it was brought by the locking pin. Since the lock also carries an elevation on its part facing the walls, over which the locking pin must slide during the opening movement, whereby the lock on this side down

and accordingly the locking pin is pushed upwards and thereby into the locking hole d ^{2 of} the bolt, a completely inevitable movement takes place. . ■ ■

By gradually moving away from the axis of rotation and inevitably acting like a wedge Lock slot a particularly strong pressure and impression is achieved, so that it is possible, too very tight windows can be opened securely and just as tightly closed.

Claims (1)

Patent claim:
. Skylight window lock with a rotatable bolt hook, characterized in that the bolt hook (d ) is locked in the open position by a lever (g) rotatably mounted in the bearing block (e) of the bolt hook and controlled by the locking pin (δ ² ) and only when the window sash is closed is released again to engage the locking pin in the locking hook groove. 1 sheet of drawings.
