Locking device for sliding sashes of windows, doors or the like,

The innovation relates to a locking device for sliding sashes of windows, doors or the like, consisting of at least one pivotably mounted about a fixed, horizontal axis Hook bolt, the free end of which has a guide slot one of the Axis-bearing mounting plate, in particular a fitting rail, engages through and engages in a frame ens e it igen bolt can be engaged, as well as from a drive rod, which is in the area between the axis and the free end of the hook bolt on the Fastening plate is guided and via adjustable stops on the hook bolt attacks, one of which is effective in the locking direction and the other in the unlocking direction.

Locking devices for sliding sashes equipped with pivoted hook bolts and operated via a connecting rod of windows, doors or the like. Are already known from DE-PS 666 108 and DE-PS 10 02 656.

In the locking device according to DE-PS 666 108, the operative connection between the pivotably mounted on the wing is Hook bolt and the movable connecting rod designed so that in each case the entire travel of the connecting rod is transferred to the hook bolt.

In contrast, the closure device according to DE-PS 10 02 656 such a training that the drive rod must first perform a certain idle stroke before it can move the hook bolt in the unlocking direction. On the other hand, however, the hook bolt falls under the effect its own weight automatically returns to the locking position as soon as the return movement of the drive rod in the locking direction begins. Only in the end phase of the drive rod moving in the locking direction does the their associated, acting in the locking direction control stop on the hook bolt to attack in order to block it in the locked position against lifting.

The locking device according to DE-PS 666 108 can - due to its mode of action - only with such windows or use doors in which the movement of the connecting rod is only used to actuate the hook bolt but cannot take on other control functions.

In the case of the locking device according to DE-PS 10 02 656, it is possible to perform adjusting functions by moving the drive rod perform which is relative to the actuation of the hook

Find. The disadvantage here, however, is that these additional: i

Control functions using the connecting rod only with advance £

opposite the unlocking of the hook bolt Instead §

can find and thus already largely completed \

i must be when the unlocking movement of the hook bolt |

begins.

The application area of the locking device according to DE-PS 10 02 656 is therefore practical for such sliding sash Windows, doors or the like. Limited parallel to their plane relative to the fixed frame by a limited Measure must be raised before they can be moved horizontally (Hebe-Schiebc '"" igel).

For windows, doors or the like, where the sliding sash is without previous lifting should be moved in the horizontal direction, and / or in which the wing after the disengagement of the hook bolt from its locking device into a Ventilation tilt position can be brought (tilt & slide sash), can however, the known locking device according to DE-PS 10 02 656 cannot be used.

The innovation is based on the task of a locking mechanism;

direction for sliding sashes of windows, doors or the like of \

To create a genus specified in more detail at the beginning, which can be used universally, i.e. which is not only suitable for immediate horizontally movable sashes and for tilt and slide sashes, but

also for lift & slide sashes and lift & tilt & slide sashes can be used.

The solution to this problem is achieved according to the characterizing part of the first claim mainly in that the Hook bolt is provided in the area between its free end and the axis with adjusting cams protruding over its side surfaces is assigned to the actuating stop of the connecting rod that is effective in the unlocking direction and with this at most over about half the unlocking travel of the connecting rod in Are held engagement, and that approximately at right angles to the effective in the unlocking adjusting stop on the rear the connecting rod formed support stop connects against which the adjusting cams of the hook bolt on the other Support the unlocking travel.

The main advantage of such a locking device is that the hook bolt immediately with the unlocking adjustment movement the drive rod in its unlocked position is brought and fixed in this, while the further movement of the connecting rod to carry out additional Control functions takes place. But it is also advantageous that during the return movement of the drive rod in the locking direction of the Hook bolt is only moved from its unlocked position into the locked position after the drive rod has completed its additional control functions.

A further development feature is seen according to the second claim that the hook bolt is a Longitudinal slot in the drive rod reaches through and the unlocking positioning stops are formed by the transverse edges of slot extensions, while the support stops longitudinal edge areas of the narrow slot section adjoining the slot widenings are used.

The advantage of this configuration is that the operative connection between the hook bolt and the connecting rod is made elected in a particularly simple manner.

Another expedient development of a locking device according to the innovation is characterized according to claim 3, that the free end of the hook bolt carries laterally projecting support cams which are in the unlocked position of the hook bolt rest against the outside of the mounting plate and thus limit the pivoting angle of the hook bolt. A compact and in practical use particularly functional design of the locking device results when after the fourth claim of the hook bolt has an approximately horse's head-like contour shape and the adjusting cams with at least one partially cylindrical lateral surface tangent to a straight line which is laid through the axis and the free end of the hook bolt. A The swivel angle for the hook bolt of 45 is sufficient to bring it from the unlocked position into a secure locked position.

a section along the line IX-IX in FIG. 6.

In Figs. 1 to 4 of the drawing, a window or door is shown, which consists of a stationary frame 1 and a wing 2 which is displaceable in the horizontal direction relative thereto.

In the closed position, the wing 2 is locked on the stationary frame 1 via a locking device 3. This exists from a fitting rail 4, one behind this slidable, and by an operating lever 6 via a crank mechanism 7 or the like. Actuatable drive rod 5 and through the drive rod 5 adjustable hook latches 8, which with the frame-side Lock engagements 9 come into and out of operative connection.

Are the hook latches 8 by actuating the operating lever accordingly 6 disengaged, then the wing 2 can be moved horizontally relative to the fixed frame 1 by means of the carriage 10 will.

The locking device built into the wing 2 of the horizontal sliding window or the horizontal sliding door according to FIG 3 has basically the same design as the locking device 3 according to FIG. 1. One difference, however, is that

are built into the wing carriages 11, which have a lifting device 12 have. The lifting device 12 is actuated via a drive rod 13 which is guided via a corner deflection 14 is coupled to the drive rod 5 of the locking device 3.

If the operating lever 6 is actuated in this case, the hook bolts 8 are first disengaged from the bolt engagements 9 and then the drive rod 13 is used for lifting 12 actuated for the carriage 11 and the wing 2 is raised relative to the fixed Eahmen 1 to a limited extent before it can be moved in the horizontal direction.

In Fig. 3 of the drawing, a horizontal sliding window is shown, in which the wing 2 can be moved relative to the fixed frame not only in the horizontal direction, but also in a ventilation tilt position can be brought. To this end

; are extension arms 15 ge on the upper horizontal wing limb

stored in a guide rail 16 on the fixed frame

p: intervene. The actuation of the extension arms 15 takes place via a

\ f ( Driving rod 17, which is connected to the driving rod by a corner drive 18

The carriages 10 are also useful here for the horizontal displacement of the sash 2 relative to the stationary frame 1.

In Fig. 4, a window or a door is shown in which the fixed frame 1 is a lift-tilt-sliding sash

2 is assigned. So that all movement functions of the wing 2 can be performed with the drive rod 5 of the locking device 3 not only the lifting device 12 for the carriage 11 coupled via a drive rod 13 and the corner drive 14, but there are also the extension arms 15 mounted on the wing 2, which are inserted into a running rail 16 of the stationary frame 1 and engage with the drive rod 5 of the locking device

3 via a corner drive 18 and a drive rod 17 in an adjusting connection stand.

5 to 9 of the drawing are the structure and mode of operation of the hook latches 8 and associated frame-side latch engagements 9 equipped locking device 3 can be seen.

In the fitting rail 4, which is U-shaped in cross section, the drive rod 5, which is flat in cross section, is at the rear of the Profile web 4 'slidable lengthways.

At a distance behind the drive rod 5, horizontally extending bolts are fastened in the legs 4 ″ of the profile rail 4, the bearing axles 19 form, on which the hook latches 8 are held pivotably by means of bearing eyes 20 located at their rear end.

r ~ ■■■

With the free end 21 of each hook bolt 8 engages through a guide slot 22 in the profile web 4 ″ of the profile rail 4 as well also a longitudinal slot 23 in the drive rod 5.

The hook bolt 8 preferably has an approximately horse's head-like outline and is in the area between its free End 21 and the bearing axis 19 with over its side surfaces protruding adjusting cams 24 are provided, which have an at least partially cylindrical outer surface 24 ′ and a straight line 25 tangent which through the bearing axis 19 and the free end the hook bolt is placed.

A high stability of the adjusting cams 24 results when they through the rounded end of to the side surfaces of the hook bolt 8 molded, thumb-like elevations 26 are formed.

The upper transverse edge of the longitudinal slot 23 interacts with the arcuate one Limiting edge 27 of the hook bolt 8 together as an adjusting stop 28, via which the hook bolt 8 from the unlocked position 6 can be pressed into the locking position according to FIG. 5.

The lower transverse edges of an extension 29 of the longitudinal slot 23 also form adjusting stops 30, namely these are the Adjusting cam 24 of the hook bolt 8 assigned to this from its locking position according to FIG. 5 in the unlocking position to be able to bring to Fig. 6.

The narrowed slot part 31 located below the adjustment stops 30 forms with its on the rear side of the drive rod 5 located longitudinal edges at right angles to the adjusting stop 30 directed support stops 32, which also with the adjusting cams 24 can come into operative connection immediately after the hook bolt has moved out of its locking position according to FIG. 5 has reached the unlocked position according to FIG. At this moment, namely, slide the adjusting cams 24 out of the area the slot widening 29 and thus from the positioning stop. 30th from and get behind the back of the drive rod 5, so that in the course of the further upward movement of the drive rod 5 the from the longitudinal edges of the narrower slot section 31 formed support stops 32 run in front of the adjusting cams 24 and over this block the hook bolt 8 in the unlocked position according to FIG.

After the hook bolt 8 has entered its unlocked position 6 by means of the drive rod 5 executable, further adjusting stroke can be according to the respective needs be chosen because it is practically only dependent on the respective length of the narrowed slot part 31.

During the return movement of the drive rod 5, the longitudinal edges of the narrowed slot part 31 are initially formed Support stops are brought out of the area of the adjusting cams 24 so that they can reach the adjusting stops 30 again. then the upper adjusting stop 28 of the longitudinal slot 23 hits the arcuate delimiting edge 27 of the hook bolt 8 and presses

\: ί this from the unlocking position according to FIG. 6 after

κ 'down into the locking position according to FIG. 5. As a result

; '. then pivot the adjusting cams 24 of the hook bolt again

ί Set and set via the adjusting stops 30 of the connecting rod 5

thus certain that with a later upward movement of the

|) The connecting rod 5 of the hook bolt 8 again from the locking

position according to FIG. 5 into the unlocking position according to FIG. 6

can be brought.

It is important that the hook bolt 8 immediately at the beginning of the upward movement of the drive rod 5 from the locking ^ position according to FIG. 5 into the unlocking position according to FIG. 6 arrives and then their further upward movement can take place, so to speak, with an idle stroke relative to the hook bolt 8.

During the downward movement of the drive rod 5, it is the other way round, i.e. first the relative idle stroke of the drive rod 5 takes place at Hook latch 8 instead, while only in the final phase of the downward movement of the hook latch 8 from its unlocking position according to FIG. 6 moves into the locking position according to FIG. 5.

The unlocking position of the hook bolt 8 relative to the rail 4 is limited by the fact that the free end 21 of the same carries laterally projecting support cams 33, which in the unlocked position of the hook bolt 8 laterally next to the longitudinal edge end Guide slot 22 come to rest on the outside of the profile web 4 '.

-15-

From FIGS. 5 and 6 it can also be seen that the free end 21 of the Ilakenriegel has a rounding 34 and on the side surfaces of the support cams 33 converging in a wedge shape As can be seen particularly clearly from FIG. 7, it has bevels 35.

The frame-side cooperating with the hook bolt 8 The locking engagement 9 consists of a loop 37 which forms the head of a threaded pin 36 and which two are diametrically opposed opposite engagement openings 38 'and 38 ". Each of these engagement openings 38' and 38" of the loop 37 is included provided with rounded or beveled inlet edges 39 ', 39 "or 40', 40", as can be clearly seen from FIGS. 5, 6 and 9 can be.

From Fig. 9 it can also be seen that the head of the drill-in threaded pin 36 has an approximately circular circumferential contour and is sunk in the lower end region of a long, circular cutout 41 of the fixed frame 1 is seated.

By rotating the threaded pin 36 provided with a low pitch thread, the loop 37 forming the locking engagement 9 can be displaced in fine steps in the horizontal direction and parallel to the plane of the stationary frame 1, in such a way that either its engagement opening 38 'or its engagement opening 38 "aligns with the hook bolt 8 Thus, a fine adjustment of the engagement conditions between the hook bolt 8 and the row Ie in ^{size 4} ff 9 is possible

8 in the locking engagement 9 acts its rounded end face 37 with the rounded inlet edge 39 'or 39 "of the loop 37 together, while its wedge-shaped converging Bevels 35 come into operative connection with the beveled inlet edges 40 'and 40 "of the loop 37 can.

When the locking device 3 is in its unlocked position is located and the wing 2 is opened relative to the fixed frame by sliding horizontally, it turns out It is particularly advantageous that neither on the wing 2 nor on the fixed frame 1 protruding fitting parts are arranged that could injure people passing through or tear their clothing.

It is particularly important, however, that there is a locking device 3 of the type shown in the drawings and explained in detail above, practically universal for the most diverse Types of horizontally sliding windows or doors can be used.
