The invention relates to a device for influencing the opening and / or closing movement of a wing of a door or a window, with a disposed between the wing and a fixed frame sliding arm rotatably mounted on the one hand on the wing or on the frame and on the other hand by means of a sliding block in an am Frame or wing arranged slide rail is guided.

An attenuation of the opening movement and a delay of the closing movement of the wing are not realizable especially in door closers either not or only in a predefined door opening angle range. However, the possibly required default brings now in certain cases an unwanted closing behavior with it. If a door can be opened, for example, up to an opening angle of 180 °, it makes little sense if the opening damping, for example, already starts at 60 °. The comfort is impaired in such a case rather. The same applies to the effective range of a closing delay.

In the DE 36 04 091 C2 a mechanical closing sequence control device for a two-leaf, a passive leaf and a wing is described comprehensive door. One such task is to securely hold the active leaf while the leaf is still open.

From the WO 2010/052 012 A1 a locking device for a door closer for detecting a door in a desired open position is known, which blocks a slider in a guide rail.

The invention has for its object to provide a device of the type mentioned, with a respective damping of the opening movement and / or delay the closing movement of a door or window sash feasible in a simpler manner and the respective opening loss or closing delay variable to the respective installation customizable as well as easily retrofitted.

The object is achieved by a device having the features of claim 1. Preferred embodiments of the device according to the invention will become apparent from the dependent claims, the present description and the drawings.

The device according to the invention for influencing the opening and / or closing movement of a wing of a door or a window comprises a sliding arm arranged between the wing and a fixed frame, which rotates on the one hand on the wing or on the frame and on the other hand by means of a sliding block in a sliding frame Wing arranged slide rail is guided. In addition, the device comprises in the slide integrated or associated with this variably adjustable means for damping the opening movement and / or delaying the closing movement of the wing.

Due to this design, the respective opening damping or closing delay is not only easier to implement, it is also variable to the particular installation customizable and easily retrofitted. For the respective user, this results in a higher level of comfort. The respective opening damping or closing delay can be used with all types of slide door closers, wherein the same system can be used for different door closer. After the variably adjustable means for opening damping or closing delay integrated in the slide or assigned to this, the measures provided for the opening damping or closing delay hydraulic, valves, seals, etc. in the closer can be omitted. In addition, for example, two opening damping areas are possible.

According to a preferred practical embodiment of the device according to the invention, the means for opening damping and / or closing delay comprise a housing, a piston arranged in a receiving space of the housing and a driver coupled to the piston and co-operating with the sliding block during a predeterminable phase of the opening or closing movement ., Closing movement of the wing with the sliding block is engageable.

In this case, the driver is preferably guided in a slotted guide of the housing so that it is engaged with the sliding block during the predeterminable phase of the opening or closing movement of the blade and releases the sliding block during the remaining opening or closing movement.

In addition, the device may in particular also be designed so that both an opening damping and a closing delay takes place.

The driver is expediently coupled via a piston rod with the piston, which is articulated on the one hand on the driver and on the other hand on the piston.

In particular, in the case that both an opening damping and a closing delay to take place, the piston is preferably designed without check valve to form a respective damping chamber on both sides of the piston.

If the device instead only causes an opening damping or only a closing delay, the piston is expediently provided with a check valve to form a damping chamber on one of the two piston sides and to form a non-pressurized space on the opposite side of the piston.

It is also particularly advantageous if at least one throttle valve is assigned to a respective damping chamber. About such a throttle valve in particular the respective damping or deceleration effect is variably adjustable.

In certain cases, it is also advantageous if the device comprises a spring unit that studs the driver or the piston, in order in particular to support the closing movement of the sash.

Another preferred practical embodiment of the device according to the invention is characterized in that on the opposite sides of the piston, a damping chamber and a particular pressureless space are provided and in the damping chamber, a return spring is arranged, during the predetermined phase of the opening or closing movement of the wing , in which the driver is engaged with the sliding block for the opening damping or the closing delay, is tensioned in order to reset the driver subsequently after the release of the sliding block. In this case, the return spring unit may comprise, for example, a compression spring.

Preferably, the driver is pivotally hinged to a slide guided in the housing and provided with a ramp, which cooperates with a housing-fixed stop such as a bolt or the like to release the follower after the predetermined phase of the opening or closing movement of the wing of the sliding block to pivot into a release position.

During the predetermined phase of the opening or closing movement, in which the driver is engaged with the sliding block, the return spring unit is thus tensioned. After the subsequent release of the sliding block with the impact of the driver on the housing-fixed stop the return spring unit is then released, after which the driver is reset. In this phase, the sliding block is out of engagement with the driver.

The driver is expediently coupled via a piston rod to the piston, which is articulated on the one hand on the slider and on the other hand on the piston.

According to a further preferred embodiment of the device according to the invention, the latter additionally comprises means integrated in the slide rail or associated therewith for additional time delay or short-term interruption of the closing movement of the blade.

In this case, these means for additional time delay of the closing movement of the wing advantageously comprise a locking wedge of which the sliding block is held after its release by the driver following the predetermined phase of the closing movement of the wing until the effect caused by the return spring arranged in the damping chamber in particular throttled Return of the driver is at least substantially done.

With this design, a mechanically realized time delay element results, by which the closing movement of the door or window wing is additionally delayed or briefly interrupted after an initial damping.

A respective damping chamber adjoining the piston can advantageously be assigned both an overpressure valve and a regulating valve. In this case, the regulating valve, for example, contain open-pore foam, is compressed by a screw or the like.

It is particularly advantageous if the driver for releasing the temporary opening delay or closing delay from the piston or the piston rod is releasably displaceable and in a neutral position, in which he no longer engages with the sliding block. In principle, however, other measures for the respective deactivation of the opening damping or closing delay are conceivable.
