The electrical drive is designed as a linear drive with a stator part (5) and a rotor part (6), where a movement of the flexible window element is caused by an electromagnetically generated linear motion of the rotor part over the stator part. The frame arrangement is formed of two longitudinal profiles (7) that are extended in direction of a motion of the window element.

Description

The present invention relates to a sliding window, in particular for installation in a roof of a building, in a wall, a facade or the like. At least one movable window element is provided in the sliding window, which is accommodated in a frame arrangement and can be moved by means of an electric drive between a closed position and an open position.

For sliding windows electric drives are known, which act on a spindle system or a traction means on the movable window element. If the electric drive is designed in the manner of a spindle system, a motor sets a spindle in a rotational movement, wherein a spindle nut is connected to the window element. By the rotational movement of the spindle, the spindle nut extends along the spindle axis, and the window member can be moved between a closed position and an open position. Spindle drives have the disadvantage that the achievable speed of movement of the spindle nut and consequently that of the movable window element is very low. In particular, when the movement of the window element is triggered by an electrical button, a person must hold the button for a considerable period of time to move to the desired position of the window element. Furthermore, spindle drives cause considerable operating noise, which are undesirable depending on the installation situation of the sliding window. The spindle must be integrated into the frame assembly, depending on the total length of the travel between the closed position and the open position, a long spindle is required, which causes possible vibration problems when it is set in rotation.

If the electric drive is designed with a traction means, then only a small traversing speed can often be realized here as well. In addition, traction drives require a considerable amount of space, since a drawstring, a pull rope or a chain must be deflected. In addition, a transmission is required, since usually drives a Urnlenkrolle, around which the traction means is steered.

It is therefore an object of the present invention to provide a sliding window with an electric drive, which has a simple structure and which is space-saving integrated into the frame assembly.

This object is achieved starting from a sliding window with an electric drive according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that the electric drive is designed as a linear drive with a stator and a rotor part, in which the movement of the window member can be caused by an electromagnetically generated linear movement of the rotor part over the stator.

Hereby, a novel drive for a sliding window is provided, which avoids the disadvantages of the above-mentioned prior art. In particular, the electric drive is not directly limited in the manner of a linear drive both in the movable length and in the achievable travel speed. Thus, the disadvantages of a spindle drive can be overcome, since too large a free length of the rotating spindle leads to vibration problems. A linear drive with a stator and a rotor part is very space-saving executable, so that the dimensions of a sliding window with a linear drive does not turn out much larger than a sliding window without an electric Drive. The stator part and the rotor part are formed flat and have a longitudinal extent, which can be aligned in the direction of movement of the window element.

A linear drive has a stator part and a rotor part, and is generally also referred to as a linear motor or as a traveling field machine. In general, a linear motor is an electric drive machine that has a linearly movable rotor part instead of a rotating armature. In principle, the inventive solution comprises both a linear drive, which operates as an asynchronous or as a synchronous drive machine, so that the magnetic field is either fixed or not firmly coupled with the movement of the rotor part. In the stator part, a longitudinally moved magnetic field is generated, by means of which the rotor part is driven translationally by magnetic interaction. By energizing the stator and a corresponding electrical drive to generate the traveling magnetic field, a relative movement between the rotor part and the stator is generated, so that this relative movement can be used to cause the movement between the moving window element and the resting frame assembly,

According to an advantageous embodiment of the sliding window according to the invention, the frame arrangement has at least two longitudinal profiles extending in the direction of movement of the window element, the linear drive being integrated in at least one of the two longitudinal profiles. For large movable window elements, which have a considerable mass, two linear motors can be provided, which are integrated in both the first and in the second longitudinal profile. Furthermore, two linear drives can be advantageous if the window element has a large width transversely to the direction of movement in order to avoid tilting of the window element in the frame arrangement. By receiving the linear drive in at least one of the longitudinal profiles of this is neither visible from the outside of the sliding window, nor is the linear drive Exposed to environmental influences. In particular, when the sliding window comprises another stationary window element, above or below which the movable window element is pushed in the open position, the height of the frame arrangement has a greater value, so that the linear drive with the stator part and the rotor part in a simple manner in the Longitudinal profile can be integrated.

Advantageously, the stator part is arranged resting in the longitudinal profile, wherein the rotor part is connected to the window element in order to transmit the linear movement of the rotor part to the window element. The rotor part can be designed to be shorter than the stator part, so that the rotor part runs along the length of the stator part and moves along the window element. The longitudinal profile of the frame arrangement can be such that the stator part is received longitudinally in the longitudinal profile and the rotor part can run along in the longitudinal profile. The rotor part is connected to the window element, for example via a connecting element such as a bolt, a screw, a driver geometry or the like. The compound may be designed as a latching connection, which is selectively releasable. Advantageously, the connecting element between the rotor part and the window member has a compliance to compensate for inaccuracies in the guidance of the rotor part and the window member, which is formed by the longitudinal profile.

According to a further embodiment, the rotor part on rollers, which are guided in a guide portion of the longitudinal profiles. The rollers may be connected via roller axes with the rotor part, wherein a total of four roller axles may be provided, and wherein on each end side of the roller axle, a roller is arranged. Consequently, there is an arrangement of eight rollers to ensure a reliable guidance of the rotor part in the longitudinal profile.

Advantageously, the longitudinal profiles have a receiving area for receiving the stator part, which is arranged such that the stator part is inserted in the receiving area in a resting position and the rotor part is movably guided over the stator part at a given distance. Consequently, an air gap is formed between the rotor part and the static stator part, which should be as small as possible in order to achieve a high efficiency of the linear drive. On the other hand, it should be avoided that the rotor part touches the stator part during its running movement. The receiving area for receiving the stator part is arranged in the longitudinal profile such that the rotor part is arranged between the stator part and the window element. Consequently, a direct connection of the rotor part with the window element is possible, wherein the guide portion encloses the rollers U-shaped to provide not only a support guide of the rotor part, but the guide in such a way that the movement of the rotor part along the direction of movement of the window element is the only remaining degree of freedom is.

The longitudinal profiles have a sliding guide portion, which is designed for sliding on both sides of the longitudinally movably received in the frame assembly window element. The sliding guide section is arranged above the guide section for guiding the rotor part over the rollers, wherein the rotor section has an extension in the direction of the glitter guide section, so that it can be fastened directly to the window element. The longitudinal profiles are G-shaped, and close the frame assembly to the outside. The guide portion for guiding the rotor part and the receiving area for receiving the stator part are closed both inwardly and outwardly so that only the window element extends from the G-shaped longitudinal profile toward the center of the sliding window. The longitudinal profile may be provided for receiving two or more window elements, wherein one of the two window elements is immovably inserted in the frame assembly. There are also two moving ones Window elements are possible, which are movable by means of the linear drive between a closed position and an open position, wherein a third window element is in turn received dormant in the frame assembly.

The linear drive can be drivingly connected to one of the two window elements in operative connection, wherein the non-driven window element is brought into contact with the driven window element in such a way that it can be moved at least in sections by the movement of the driven window element. If the first window element is moved by the linear drive, for example, from the closed position to the open position, then the first window element can have a stop edge, which then abuts against the second window element if the first window element covers the second moving window element. Thus, the second window is dragged along by the movement of the first window, and the movement of the second window from the open position to the closed position works in the opposite way as well over a stop or driving edge. According to a further embodiment, however, a linear drive is also possible for each individual window element in order to control these individually and independently of one another. In the context of the present invention, the number of window elements within the sliding window is not limited, so that the sliding window can also have a plurality of individual window elements, which are either movable with each other via a respective entrainment of the window elements or each have their own linear drive.

For controlling the linear drive, a control unit is provided, which may be located in the sliding window or in an external arrangement remote from the sliding window, and is connected via an electrical connection to the stator. The control unit can also serve for the power supply of the stator and this drive at the same time. The movable Magrtetfeld generated over the stator can be controlled via the control unit in the direction of movement and the strength and the speed of movement, wherein the control unit can also be integrated in the stator. For example, the control unit may be controllable by means of a radio remote control in order to move at least one or more window elements between the closed position and the open position. In particular, when the sliding windows are integrated in roofs, which have a facade structure, cabling can be minimized by the control unit is controlled by a radio remote control.

According to a continuation of the technical equipment of the linear drive, the control unit may be connected to position sensors which transmit information about the position of the at least one window element to the control unit. These can also be provided in the form of limit switches to ensure that the linear actuator moves the window element only within the given range of motion.

Advantageously, there is also a locking device which locks the window element in the closed position, in the opening position and / or in any other arbitrary intermediate position. The locking device may have at least one locking bolt, which can be moved by means of an electric motor and by means of a lifting magnet for locking engagement in the window element. The locking bolt is in the form of a linearly movable bolt or a pivotably arranged hook, and may cooperate with the window member such that upon activation of the locking device, the window member is pulled to an end position, for example, to retract the window member into a sealing arrangement. This eliminates the need for the linear actuators permanently either in the end position or in an intermediate position of the window element to energize, and the locking bolt can be arranged spring-loaded so that the locking device must only be energized when the linear drive is activated.

Advantageously, the guide of the window element within the frame assembly may comprise a friction or a braking device which acts permanently on the window element. The force necessary to move the window member against the frictional or braking force of the device is such that the window member can not move within the frame assembly due to its own weight. However, the frictional force is limited so that the linear drive can overcome this, without the linear drive must be sized much larger. As a result, the window element remains at the desired position when the current to the linear drive is interrupted. Such a friction or braking device may comprise a spring-loaded friction or brake pad which acts against the frame of the window element. Especially with vertically mounted sliding windows with vertically moving window element, the weight of the window element must be kept, so that the friction or braking device must be dimensioned accordingly.

The frame assembly of the sliding window comprises at least two longitudinal profiles which are interconnected at the ends by transverse transverse profiles in order to create a closed frame arrangement. The locking device can be present in the transverse profile, so that it does not appear from the outside of the sliding window in appearance.
