causes the window to lock immediately.

The invention and advantageous details of the invention are described below on the basis of schematic drawings explained in more detail using an exemplary embodiment.

. 1 is an abbreviated partially drawn in section Side view of a device according to the invention with a linkage for locking a window.

FIGS. 2 to 6 are cross-sections along the lines H-II ₁ HI-III ₁ IV-IV, VV and VI-VI in FIG. 1.

7 shows, in perspective, on a smaller scale, a window equipped with two devices according to FIGS. 1 to 6. . ^;

According to the drawings, each of the two devices comprises of which only one is described below, a channel-shaped guide comprising two sections 1 and 2, the embedded in the relevant side edge of a window frame. 3 can be, which according to Fig. 7 on a stationary Window frame 4- "is rotatably mounted on his lower hand. As already indicated, there is one according to the invention on each of the two side edges of the pivotable window frame or window frame Device provided.

There is a long latch part in the channel-shaped guide 5 of generally D-shaped cross-section, the upper End 6 for engaging in a fixed window frame 4 · built-in locking sleeve can be brought. The lower jSn & e of the locking part 5 is hollow on one in one Housing 8 slidably guided bush 7 attached. In the housing 8 is a compression spring designed as a helical spring arranged, which is located between a in the lower end of the Housing built-in plug part 10 and the socket 7 supports, around the locking part 5 upwards towards its locking position to pretension. On the housing S is a radial fixed inwardly protruding guide pin 11, which is in a a slot 12 of the bushing which forms a cable of a screw thread

7 engages Here, the arrangement is such that the locking part 5 moves in the direction of its longitudinal axis, that the guide pin 11 with the slot or the groove

12 cooperates to bring about a rotary movement of the locking part.

"I.
Near the upper end of the locking part 5 is a handle which is rotatably mounted on the window sash 3 with the aid of an axis 14-

13 is provided which has a forked end 15, the Legs overlap the bolt part in a space that is held by two on the bolt part at a longitudinal distance from each other

P ■ -. fixed rings 16 and 17 is demarcated · Will handle in; the pivoted \ in FIG. 1, indicated by dash-dotted lines STEL lung, the latch member is against the biasing force of the spring 9 from its Verriegelüngsstellung down. moved and brought into a withdrawn position. During this downward movement, the guide pin 11 cooperates with the groove 12 in order to rotate the locking part clockwise according to FIGS. 5 to 6;

Furthermore, each device is provided with a flat rod element 18, which is rotatably connected at its lower end by an axis 19 to a support piece attached to the stationary window frame 4. The upper end of ρ ■ linkage member is a groove is provided for receiving the latch member 5 \ 23 by a shaft 21 join with a slidingly guided in the channel-shaped guide portion 1 log-shaped member or slider 22 ^ which is closed by a leaf spring 24 which is supported on the locking part, and the ends 25 and 26 of which bear against the guide section. The surface of the slider 22 facing away from the groove 23 is covered with a friction-generating coating 2? provided, which cooperates with an inner wall of the guide section 1. When the locking part 5 is in the angular position shown in Fig. 3, the leaf spring 24 is tensioned so that it presses the friction-generating lining 27 against the adjacent inner surface of the guide section 1 so as to prevent any movement of the slider 22 5 against

clockwise above its angular position according to Fig. 3 by Turned 90 ° »the flattened side of the locking part is like this arranged that it faces the leaf spring 24 so that the leaf spring is relaxed and the slider 22 can move unhindered along the guide · ν

If two of the devices described are attached to a window sash, the window sash is held in the closed state in that the bolt parts or locking rods arranged on both sides engage with their upper ends 6 in matching openings in the stationary window frame. In order to release the window sash, both handles 13 have to be swiveled upwards so that the locking bars 5 are brought down from their locking position into a retracted position and at the same time are rotated so that the friction-generating linings 27 are no longer pressed against the guide sections 1 "The sliding pieces are now freely movable and the window can be opened to any desired extent." Once the desired üffnungsstellung is reached, allows even the release of one of the handles 13 of the associated compression spring 9 to rotate the locking bar in question back to its locking position according to FIG ₀ 3, so that the friction-generating pad 27 is pressed against the associated guide to to secure the window sash against any further movement »

It should be noted that a wide variety of modifications can be made to the device described. For example the locking bar does not need a D-shaped cross-section to have, but it can have any non-circular • cross-section that "enables the locking belt described and to bring about unlocking action. The cross-section of the locking rod does not need too much either whose entire length [to be constant. Also the use of the Socket 7 is not absolutely necessary, but you can the hat'12 on the circumferential surface of an extension of the massive Also, the arrangement of the guide pin 11 and the groove 12 can be reversed, i. E.

Hjan can build the pin firmly into the locking bar and form the groove in the housing 8. The connection too between the handle 15 and the locking bar 5 can be modified.

Changes can also be made to the arrangement, by means of which the slide 22 relative to the guide; can be set. For example, it can be ensured that causes rotation of the locking bar. that min ^ at least part of the slider is spread so that a firm frictional engagement between the slider and the guide ^ part is achieved «■
