Description

The invention relates to a drive with an adjusting device for a sliding wing as lifting slide sliding or lifting sliding sash for a window or a door according to the preamble of claim 1.

The sliding wings of systems as lift-slide sash or lift-slide sash for a window or door often have a relatively high mass. In particular, when lifting the wing must be taken to open a high torque. Also, closing requires application of resistance to the weight of the wing to avoid abrupt dropping of the wing. The known drives with an adjustment are mounted without further cover, so severely affects the appearance and do not provide enough protection against possible incoming dirt, for example, by incident chips, which may damage the drive with the adjustment result. Likewise, the risk of injury during assembly is increased by disturbing overhead visible components. Furthermore, visible components offer more possibilities for manipulation from the outside. An assembly of such a drive with the adjustment, turns out to be complicated from the known prior art.

From the DE 10 2005 002 180 B4 For example, there has been known a control device for a lift-and-slide wing having at least two carriages each having rollers to be slid on a track in a direction parallel to the extension of the lift-and-slide wing or along the track. In a vertical rail, an electrically driven lifting drive and two vertical control rods is arranged, of which a control rod at the lower end of Vertical rail is coupled via a deflection and coupling device with the carriage, for adjusting the height position of the rollers, and wherein the second control rod of the at least two control rods is coupled to the lifting drive.

The two vertical control rods are thrust coupled across transverse arms in a transmission housing so that movement of the second control rod driven by the linear actuator is transferable to the first vertical control rod.

The present control device is large in construction and requires a corresponding amount of space in the wing. Furthermore, the components of the control device are distributed widely spaced from each other along the length of the guide rail, which complicates assembly due to individual component components. The functional components of the control device are also unprotected against dirt and other influences in the wing.

Further, reference is made to the DE 11 2007 002537 T5 with a lifting and sliding device with an arrangement according to the preamble of claim 1. Here, the lifting and sliding device for a window, a slide rail for lifting a sash and a service plate for operating the slide rail and is operated in such a way that the Operating plate is moved vertically by means of an electric motor unit. Further, on the DE 101 22 261 A1 referenced with a drive for a Parallelabstellfenster, which with steel tape u. Shift linkage is provided and has an adjustment mechanism for a parallel adjustment mounted on the shift link link pins and attached to the frame link curves. Alternatively, a gear / handle her hand adjustment is provided. A drive element consists in a unit of a drive, a steel band and a shift linkage. Between these there is a compound via connecting elements. A coupling element between the drive and the shift linkage has connections of the drive element.

Also known is a tongue gear for locking or unlocking a sliding wing after the EP 2 206 862 A2 , To be at a manual or motor movable wings to ensure reliable locking of the wing in its closed position and to provide a corresponding tongue gear available to a tongue gear for locking and unlocking the wing is proposed relative to an associated frame. The transmission consists of at least one tongue housing which is coupled to a drive rail slidable back and forth by a predetermined amount and has a locking tongue pivotable in the housing about an axis between a first position retracted into the tongue housing and a pivoted locking position. The pivoting tongue protrudes in the pivoted position by reaching into alignment or alignment openings in superimposed drive rail and cover rail in a wing-mounted closing piece. The drive rail is alternatively displaceable by an electric motor drive unit or by a manually operated gear.

The object of the present invention is therefore to eliminate the known deficiencies and in contrast provides with little effort and at low cost a drive with an adjustment for a sliding wing as lifting sliding sash or lifting sliding sash for a window or a door ready, in addition in a simple, fast, safe and precise way, also retrofitted and adjusted, and can be dismantled.

This object is achieved by an arrangement with the features of claim 1. The drive and the adjusting device are to be arranged so that they are suitable for a sliding wing as lifting slide sliding or lifting sliding sash for a window or door. In this case, the wing at least two carriages, each with rollers to be moved on a running rail in a direction parallel to the extension of the wing or along a running rail. An arranged on the closing side of the window or the door vertically on the spar of the wing fitting, which receives the electrically driven drive and the adjusting device, transmits a drive rod over the electrically generated by the drive and the adjustment stroke on the at the bottom of the wing a deflection and coupling device arranged carriage, which allow an adjustment of the altitude of the rollers.

To operate the sliding wing, an actuating element with a switch is arranged on the vertical spar of the wing, which switches the drive with the adjusting device for opening or closing.

The movable wing can be brought relative to the fixed frame and the fixed mounted wing or door panel from the closed position to the raised open position. In the raised position can then move the wing in a relation to the fixed frame and the fixedly mounted wing or fixed door panel, but on the other hand also bring into a secure shifted ventilation position or a portion of a through hole. For this purpose, the drive is preferably added to the adjusting device in the mounted state in a U-shaped profiled guide rail. The drive has a circuit board, a motor and a transmission which drive a clutch. With power transmission from the clutch to the adjusting a arranged in a guide rail fitting displaced displaced. The individual components of the adjusting device are completely enclosed in a housing, wherein the housing enters into a dimensionally stable fixed connection with the guide rail.

The motor, in particular the electric motor, is connected to the transmission and the circuit board and forms a unit fixed to one another as a drive. The transmission is connected via the coupling with a spindle to drive a carriage. The spindle is preferably rotatably supported on two bearings and mounted axially non-displaceable. The carriage, however, is rotationally fixed in the housing, but arranged movable along the guide rail. For this purpose, the carriage is rotatably connected by means of a threaded portion with the spindle and has a bore in extension of the central axis. The bore allows for a more stable hold and reduces the bending moments of the spindle, with the spindle in the bore additionally held leader. Preferably, the bore is arranged on both sides of the threaded portion. Thus, the support surface of the carriage in the housing and on a drive rod of the fitting is increased simultaneously in the longitudinal direction. This absorbs forces to be absorbed, for example the Reduces braking force and increases a counteracting lever, so that the wear is reduced.

A drive shaft of the transmission is provided with a first coupling part of a dog clutch, which is in engagement with a second coupling part of the clutch. The claws of the coupling parts are not directly adjacent to each other, but are separated by a coupling ring of an elastic material. Through the interaction of the components of the coupling existing clearance or tolerances is compensated.

For easy coupling of the adjusting device with the fitting, the carriage consists of a driver and a nut. The mother is T-shaped in the longitudinal direction to the drive and has for this purpose the centrally arranged threaded portion, wherein a formation of the bore having semicircular cutout is arranged on the respective sides. The driver is U-shaped in the longitudinal direction to the drive and has a recess which is in positive connection to the threaded portion. Also, semi-circular cutouts are formed on the respective sides of the recess to form the bore. In the coupled position of the driver with the nut, the semi-circular cutouts form the bore.

To achieve a high strength and a long service life of the connection of the fitting with the adjusting device and the drive, the carriage is fastened with its driver to the drive rod of the fitting by means of a riveted joint and held in a leading position in the housing. In the region of the rivet connection with the drive rod, the drive rod is formed bent in the direction of adjustment. Possibly occurring frictional resistance by a rivet projection, on the mounted in the guide rail movement of the drive rod, are thus excluded.

In addition, it has proven to be advantageous to the function, installation and cost of the fitting that the drive with the adjusting device regardless of the installation of the other fitting to the wing is concealed mountable. The size and weight of the window or door also dictate the number of drives to the adjuster to increase the drive force when needed.

Furthermore, the adjusting device has a manually actuated emergency unlocking device for manual movement of the spindle arranged in the adjusting device with transmission to the fitting of the lifting sliding sliding wing or lifting sliding wing. For operation engages in an opening of the housing of the adjusting a manually operable tool directly to the arranged spindle, which can be rotatably adjusted.
