Description

The present invention relates to a drive unit for a movable sash, in particular a window, with a drive which drives a linearly movable drive element which is in engagement with a driver which, when moving, a drive rod of a fitting with at least one bolt for locking and unlocking of the movable wing drives a window or door and a method for unlocking a drive from a movable wing.

The DE 10 2014 111 131 A1 discloses a device for locking and unlocking a window sash, in which a locking element is arranged on a first and a second coupling element, which is adjustable from a fixing working position to an emergency unlocking position, in which the two coupling elements can be displaced relative to one another. Although this enables non-destructive emergency unlocking, numerous components are required and the adjustment during emergency unlocking can be difficult.

It is therefore an object of the present invention to provide a drive unit for a movable wing and a method for unlocking a drive from a movable wing, which has a compact structure and is easier to handle in an emergency release.

This object is achieved with a drive unit with the features of claim 1 and a method for unlocking a drive with the features of claim 10.

In the drive unit according to the invention, the driver, which is in engagement with a movable drive element, is biased by a spring to the drive element in an engagement position, and for an emergency release, the driver can be moved into an unlocking position against the force of the spring. This increases functional reliability because the spring biases the driver into the engagement position. For an emergency release, only the spring preload forces have to be overcome, which simplifies handling.

The driver is preferably mounted so as to be displaceable substantially perpendicular to the longitudinal direction of a drive rod. The driver can engage with a foot section in a receptacle between two webs of a holder, and can be prestressed against a stop which is formed, for example, by angling the webs. As a result, the emergency unlocking mechanism can be constructed in a comparatively simple and compact manner. The driver can be in engagement with the drive element with a head section projecting over the two webs in the engagement position. The drive element can have, for example, two projections which engage around the driver on opposite sides, so that the driver can be moved in opposite directions by the drive.

The driver can have an angular head section, an actuating section of a tool acting on one leg of the angular head section, which can be arranged behind a sealing strip between a sash profile and a frame profile. This makes it easier to locate the driver by means of a tool, in particular if a guide surface is formed on the tool so that the actuating section can be arranged at a predetermined distance from an outside of the sash or bend frame profile.

The drive can be designed, for example, as a spindle drive, in which a spindle that rotates relative to a spindle nut causes a linear movement of the drive element. With the spindle drive, the drive element can be moved in opposite directions to lock or unlock the sash.

The drive unit according to the invention is preferably used in a window or a door, the drive unit being arranged in a rebate space between a sash profile and a frame profile. This means that the drive unit is concealed and not visible from the outside. The drive unit can also be used with a flap or another movable wing. A plurality of drive units are preferably provided on the sash, for example in the case of a sash frame, corresponding drive units can be provided on at least two, three or four sides for locking and unlocking. The drive unit can be controlled in a wired or wireless manner, with a control of an opening system preferably controlling the drive unit.

In the method according to the invention for unlocking a drive from a movable wing, an actuating section of a tool is first inserted between a window frame profile and a wing frame profile, in order then to move a driver, which is in engagement with a drive element, against the force of a spring from an engagement position into an unlocking position, to then move a drive rod with at least one bolt with the tool. This enables a quick emergency release, for example if the power supply to the drive unit is interrupted or other problems with the Control occur. The actuating section of the tool preferably engages behind a sealing strip which is arranged between a casement profile and a frame profile, so that the locking mechanism can be arranged behind the sealing strip in a protected manner.
