Closure device for the sash of windows, doors or the like.

The invention relates to a closure device for the sash of windows, doors or the like, consisting of a window or door element, e.g. on the fixed frame, seated strikers with a locking cam and off on the other window or Door element, for example on the wing, slidably arranged locking members that have a Espagnolette gear optionally in and out of engagement with the locking cams of the locking plates are adjustable.

In known locking devices of this type, the locking members are mostly than on the drive rod of a bevel gear a riveted via bolts Roll cams formed while the strikers

a rigid locking cam on the fixed frame or counter-wing have · With these - generally as a rolling pin bevel gear - Locking devices must be the respective position of the two, the lock of the sash-effecting hardware components are carefully determined during installation, if sufficient Sealing of the closed window or door is to be achieved.

However, the use of the known closure devices is associated with various disadvantages. So In the case of wooden windows and doors, for example, the frame parts can be exposed to the effects of weather and Working under the influence of temperature and consequently more or less warping. This will naturally the locking members of the locking device are also displaced relative to the locking cams of the locking plates. Even if the window or door elements are slightly warped, this already leads to impairment the closing effect. Either = namely the The wing in the closed position is not pressed firmly enough or the pressure effect is too strong. In the former case, the sealing of the windows and doors leaves something to be desired and the

Wings tend to rattle uncomfortably. In the other Case · there is an enormous sluggishness of the window and door locks, the difficulty of operating and in some cases even bending or Breaking off of the locking links has the consequence.

In practice it often happens that the locking plates are attached to fixed taps or the frame of the counter-wing not be struck exactly with a distance corresponding to the distance between the locking members of the locking device. This occurs then in use the case that the closing pressure at the various locking points is different is great. This not only affects the tight fit of the windows and doors, but also makes a difference distortion of the wing feed. On the other hand, it is also often desirable in practice to arrange the locking devices for windows and doors to close progressively, i.e. to mount them in such a way that the individual locking points come into engagement one after the other in a certain order.

In order to meet these needs, as the German patent specification 1 185 94-8 discloses,

- 4 -0Ö982S / 1322 ^C ° ^P

Already locking devices for windows, doors or the like. Has been created in which the locking members the actual window and door lock and / or the locking plates in their position on the window or are adjustable on the door. These known locking devices are not only expensive in construction, but they also have the disadvantage that only a gradual adjustment of the locking plates and / or the associated locking members of the locking device is possible. In addition, this requires known locking device a cumbersome and time-consuming handling during the adjustment. Apparently therefore this known locking device has not been able to establish itself in practice.

The German utility model 1 990 737 already discloses a striker plate for window and door locks that enables lay-person adjustment. The position of its locking cams can simply be changed by turning a screw or an eccentric and thus adjusted according to the respective needs. However, these known striking plates are still designed to be relatively expensive because they are in addition to the

009 * 26/1322

Screw or eccentric trained adjusting member still require exact parallel guides for the locking cam on the striker.

The invention is based on the object of providing a locking device for the sash of windows, Doors or the like of the type described above with the simplest means in terms of their closing effect suitable for laymen to make adjustable.

The solution to this problem is after Invention essentially that the locking members and / or the locking cams exclusively by eccentric adjustable bolts are held and guided.

In the magazine "Baubeschlag-Magazin", issue 10/1956, page 74 »right column, there is already a roller pivot for lifting windows and lifting doors disclosed, the bearing axis of which is arranged eccentrically on a threaded shaft is. With the threaded shaft, the roller pin is inserted into a hole in the sash wood, where it is replaced by a corresponding Turn the threaded shaft the respective. Can be adjusted according to needs,

00Ö826 / 1322

if the hardware components are hung inaccurately or with the wooden frame working. However, this known roller pin has the disadvantage that, for example after repeated readjustments, the threaded shaft is no longer properly seated in the wood and therefore twisted in an undesirable manner. This disadvantage is true of the eccentrically adjustable roller pins according to German patents 1 148 467, 1 203 and 1 225 067 as well as according to the German Auslegeschrift 1 280 704 avoided, but these are known roller cams very complex in their design and also require a considerable amount of installation space.

All of these eccentrically adjustable roller pins have the disadvantage that they can only be used Suitable as locking devices for lifting windows and lifting doors.

In contrast, the invention relates to locking devices for the sash of windows, doors or the like. In which the locking members opposite the locking cams the strikers are adjustable by means of a connecting rod gear.

- 7 -009626/1322

Deviating from the known roller pin locks for lifting windows and lifting doors and also from the known ones Rolling pin edge drives is an essential feature of the invention that the locking links on the drive rod as freely rotatable rollers or seated on the eccentrically adjustable bolts Discs formed and assigned to them commercially available strikers.

Another embodiment of the locking device that is essential to the invention is also seen in the fact that the locking cams of the locking plates as seated freely rotatable on the eccentrically adjustable bolt Rollers or discs are formed and the associated sliding locking members on the drive rod are designed as claws which are U-shaped in cross section and open at least at one end. It is special advantageous if according to the invention the U-shaped claws over several individually rotatable eccentric bolts connected to the connecting rod and can be adjusted via this either parallel to itself or in an inclined position.

- 8 009826/1322

A further feature of the invention is that the bolts are difficult to rotate with the drive rod or the closing plate are riveted or caulked. This ensures that the bolts only can be rotated with a relatively high expenditure of force, so that they even after repeated Adjust safely remain in their respective set position. To achieve an activity suitable for laypersons it is according to the invention of particular importance that the bolts at their free end one Adjusting engagement, e.g. have a radial slot, for an actuating tool, which extends in the direction the eccentricity extends. This adjustment intervention also forms a visual display for the respective setting of the eccentric and thus facilitates the control of the respective setting made considerably.

With locking devices for tilt and swivel sashes of windows, doors or the like, which not only cause the actual closure of the sash, but also the mutual engagement and disengagement of the hinge joints in the two at right angles to each other directed hinge axes, there are many

- 9 -6/1322 ORIGINAL

fold the need, apart from the actual hinge joints, special center locks to "press. These additional middle locks also press the sash in its locked position to the hinge joints against the plague frame to increase the sealing effect. Both for swivel opening of the wing as well as to open the same, the center locks are disengaged.

With such locking devices, there is then damage to the when closing the wing Locking links or on the locking cams of the locking plates, if, with the wing open, the locking device has been operated so that the locking members in their position corresponding to the locking position reach. In this case, when the sash is closed, the locking members cannot next to the locking cams run into the closing plate, but they hit the face of the closing cams. In the case of the closure points located in the vicinity of the joint axis, this can have the consequence that the locking links and the locking cams are damaged or broken off by the large forces that occur thereby reducing the effect of the locking device

009826/1322

is adversely affected. But it is also damage to the connecting rod or the guides for the locking members possible, which then leads to the complete inoperability of the locking device.

The German patent specification 1 219 359 already proposes to avoid such damage been made to arrange the locking members in the wing plane perpendicular to the frame slidably on the drive rod and held by a spring in the working position, so that during the closing movement of the When the wing hits an obstacle, the locking links retreat against the action of the spring can. After overcoming the resistance, the locking members engage under the known locking device the influence of the spring, going back into its starting position intended for the closed position, behind the locking cams of the locking plates provided on the fixed frame and thereby effect the locking.

This known design of the center lock is expensive and requires relatively long and deep slots in the sash to accommodate them. The use of the spring as an actuator also makes the known design of a center lock

In the embodiment of a closure device According to FIGS. 4 to 6, a roller or disk 28 is on the closing plate 21 as a closing cam 27 a bolt 29 freely rotatably mounted. This bolt 29 has a shoulder 30 in the closing plate 21 attached, which extends parallel to the axis of rotation of the roller 28 by the extent e. Of the Approach 30 is difficult to rotate with the closing plate 21 riveted or caulked, so that the bolt 29 only by means of greater exertion an operating tool is eccentrically displaceable about the longitudinal axis of the projection 30. A radial slot 37 in the head part of the bolt 29 is used to engage the adjusting tool. It extends parallel for eccentricity e and thus also serves as a visual indicator for the respective position setting of the Bolt 29 and thus the roller or washer 28.

From Figs. 4- and 6 of the drawing it can be seen that the roller or disc 28 forming the locking cam 27 of the locking plate 21 moves away from the locking plate 21 conically tapered away. With the as lock: - Cam 27 serving roller or disc 28 of the closing plate 21 acts as a locking member 20 in cross section

U-shaped claw 31 together, which lies on the outside of a faceplate 32 and with the on Underside slidably guided locking rod 7 is firmly riveted. The inner surfaces 33 of this locking claw 31 have an inclination position adapted to the conicity of the roller or disk 28.

As FIG. 6 clearly shows, the locking claw 31 engages around in the closed position of the wing 1 the roller or disk 28 of the closing plate 21 forming the closing cam 27 on its inner surfaces 33. When the sash is pivoted open around the lateral pivot axis χ - χ, the locking claw shifts along the dash-dotted circular arc 34 opposite to the roller or disc 28. On the Arc 34 is on the one hand the locking cams 27 of the closing plate 21 forming roller 28 with its conical peripheral surface and on the other hand the locking claw 31 with its inclined inner surface 35 on. This has the advantage that when open and close the wing 1 about its lateral vertical pivot axis χ - χ even then a mutual obstruction of the locking plate 21 and locking link 20 cannot occur if

Deliberate incorrect operation of the locking device 15 moves the locking member 20 into its corresponding locking position Switch position is brought. Damage to any hardware components is thus guaranteed avoided.

Because the wing-side locking claw 31 the locking cam 27 forming roller or disk 28 of the closing plate 21, have the closing pressure absorbing Areas of locking claw 31 and roller or disc 28 a relatively large distance from the swivel joint axis χ - χ. This in turn results in the advantage that the roller 28 with a relatively weak conicity and the inner surfaces 33 of the locking claw 31 with a correspondingly weak Inclination, which need not be more than 30 °, can be provided. With this weak inclination of the active surfaces, a sufficiently large closing pressure between the closing plate is ensured in any case 21 and the locking member 20 brought about. The setting The respective desired closing pressure is done by turning the bolt 29 around the eccentric Axis of its attachment 30 within the adjustment range indicated in FIG. 5 by dash-dotted lines.

The locking device according to the Pig. 7 and 8 differs from that of FIGS. 4 to 6 in the main thing is that not only the locking cam 27 forming the roller or disc of the locking plate 21 is mounted eccentrically adjustable, but that also the locking claw connected to the locking rod 7 31 is adjustable via eccentric.

As in the case of the locking device according to FIGS. 2 and 3, the locking device according to the Fig. 7 and 8 bolts 35 by means of an eccentric extension 36 difficult to rotate with the drive rod 7 riveted or caulked. The bolts 35 carry the locking claw 31 in such a way that by turning the bolt 35 a sideways displacement of the locking claw 31 can be made. Only grips with one end a bolt 35 on the locking claw 31, while the other end of the locking claw 31 is pivotable on the The locking rod 7 is mounted, then by turning the bolt 35, the locking claw is tilted 31 a.

If, however, an eccentrically rotatable bolt 35 is assigned to each end of the locking claw 31, then can by evenly turning both bolts 35 one

009826/1322 -23-

Displacement of the locking claw 31 parallel to itself be made. Here, too, determines the extent; the eccentricity the adjustment range of the locking claw

Finally it should be mentioned that the closure devices according to FIGS. 4 to 8 are not only for It is suitable for use in the area of the joint axes of windows and doors, but also on theirs Lock side are usable.
