The present invention relates to an actuator for a window or a door having a housing intended to be fastened to the frame of a window or door, having a chain whose one end is provided to engage with the wing of a window or door a door, which is housed in a chain plane accommodated in the housing and having a plurality of chain links, wherein the chain links are movably connected in the chain plane, with a housed in the housing drive unit having a motor and a sprocket wherein the motor drives the sprocket, and wherein the sprocket engages the chain links of the chain and moves them in the chain plane, and with a chain exit opening provided in the housing, which is formed so that the chain in an outgoing in the chain plane exit direction through the chain Chain outlet opening is guided out of the housing. Another aspect of the present invention relates to a window or door having a frame and a wing, and to an actuator for pivotally driving the wing relative to the frame, wherein the actuator is formed in accordance with an embodiment of the present invention.

From the prior art, such as the EP 0 600 105 B1 , an actuator for a window or a door is known, which comprises a housing for receiving a chain and a drive unit, wherein the drive unit is provided with a motor and a gear for driving a sprocket which engages with and on the chain links of the chain Way the chain can move through a chain outlet opening from the housing or move into the housing. The chain extends in the retracted state in a guide rail which extends around the engine and the transmission. The housing is intended to be attached to the frame of a window or door, and the one end of the chain can be connected to the wing of a window or door.

Also from the DE 202 21 630 U1 For example, there is known a modular actuator for a window or door having a housing and a drive unit received therein which drives a chain which can be connected to the sash of a window or door. To supply DC power to the drive unit, a power supply is provided. The power supply is formed in a separate housing to the actuator and connected to the actuator via a cable. In addition, a control device is likewise designed as a separate module.

Due to the increasing use of insulating material on the frame of windows and doors, where the actuator according to the invention is intended to be mounted, it is desirable to form the actuator in the most space-saving manner possible.

In addition, actuating devices are known from the prior art, which have different power supply components. In addition to actuators, the drive unit is powered by a power supply by a power supply with electrical power, namely actuators are known, the drive unit is powered by a battery element with electrical power, the battery element can be charged by a solar cell.

Operated with a power supply unit as a power supply component and operated with a battery element as a power supply component actuators are formed due to the diversity of the power supply component in different ways. This is detrimental to both the end user, who, if he wants to convert from mains power to solar power, must purchase a completely new actuator, as well as the manufacturer who manufactures, stores and supplies two different types of actuators.

Therefore, it is the object of the present invention to provide an actuating device, which is designed in a particularly space-saving manner and thereby allows operation with various power supply components, such as a power supply or a battery element.

This object is achieved in that the housing has a receiving device in which a power supply component is provided for supplying the motor with electrical power, and that the power supply component is detachably arranged in the receiving device. In this case, it is particularly preferred if the receiving device has receiving contacts and the power supply component has supply contacts, wherein the receiving contacts and the supply contacts are in engagement. However, the receiving contacts can also be independent of the receiving device on the actuator z. B. may be provided on a cable which is passed through an opening in the receiving device to engage with the supply contacts of the power supply component.

In this way, various power supply components for supplying the drive unit, in particular the motor with electrical power are used, the dimensions of the actuator remain the same and also not the entire actuator must be replaced if only the power supply component, for. B. a power supply with a battery element to be replaced.

The receiving device is thus formed such that various types of power supply components, such as a battery element or a power supply, can equally be accommodated therein and can supply the drive unit, in particular the motor, with electrical power by connecting the receiving contacts of the receiving device with the supply contacts of the power supply component.

With a uniformly trained actuator larger quantities can be produced cheaper. In addition, the logistics of actuators uniform design significantly simplified. Further, a consumer who has attached an actuator according to the invention to the frame of his window or door may arbitrarily change between different power supply components if a power supply component proves to be detrimental to another after some time of use. For example, the change from a solar cell-charged battery element as a power supply component to a power supply may be useful if the window or the door is opened and closed very often. In addition, a change of the battery element is comparatively easy when the battery element after 10 to 15 years shows a reduced performance.

The receiving device is preferably designed in the form of a recess in the housing of the actuating device, for example as a rectangular recess which has an opening for insertion of the power supply component, wherein the receiving contacts are arranged in the interior of the recess.

In a preferred embodiment, the power supply component supplies DC power, and the motor is configured as a DC motor. This can be an ordinary electric motor. The DC supplying power supply component may, for. B. be a power supply or a battery element.

In another preferred embodiment, the power supply component includes a power supply that includes a rectifier to convert an AC voltage to a DC voltage that is provided to the supply contacts. In this way, the power supply component can supply DC power to the DC motor. In addition to the rectifier, the power supply unit preferably has a voltage converter. In order to connect the power supply unit for supplying an alternating voltage with a power cord, in the wall of the receiving device further comprises a through hole may be provided through which the power cord can be guided and connected to the power supply unit. The passage opening may preferably correspond to the dimensions of the power cable plug, which comes into engagement with the power supply.

In another preferred embodiment, the power supply component comprises a battery element. Also, the battery element supplies DC power to the DC motor. It is particularly preferred if a photovoltaic cell is provided and if the battery element is connected to the photovoltaic cell. Thus, the battery element can be charged by the photovoltaic cell. The photovoltaic cell can, for. B. on the roof of a house, be attached, which has a roof window, in the framework of which the actuating device is mounted. It is also conceivable that the photovoltaic cell is mounted directly on the frame of the window.

In a further preferred embodiment, the housing has a fixed and a movable housing part, wherein the fixed housing part has a mounting surface along which it can be attached to the frame of a window or a door, wherein the movable housing part about a pivot axis parallel to the chain plane and is mounted perpendicular to the outlet direction pivotally mounted on the fixed housing part and wherein the chain and the drive unit are provided in the movable housing part.

In this way, the chain plane of the arranged in the movable housing part chain relative to the fixed housing part, in particular the mounting surface, to be pivoted and adapted to the current plane of extension of the wing, so that the chain plane and the connecting line between the chain outlet opening and the point at which the free end of the chain is hinged to the frame, parallel to each other. Thus, the chain undergoes no bending when the wing is pivoted relative to the frame, since the outlet opening having movable housing part of the actuator can always be moved with the wing and can be adapted to its angular position. In order to drive the chain without much effort, thus the drive unit with motor, gear and sprocket is thus arranged in the movable housing part in addition to the chain. In addition, between the fixed and the movable housing part, a spring element may be provided, which is the movable Housing part biased toward the fixed housing part. It is preferred if the spring element biases the movable housing part in a position in which the chain plane is parallel to the mounting surface. In this way, the movable housing part is on the one hand biased towards the plane in which it is arranged when the window or the door is closed. On the other hand, prevents the bias that the chain plane moves beyond the plane away from the mounting surface in which the connecting line between the point of articulation for the chain on the wing and the chain outlet opening extends. In this way it is ensured that the actuator works reliably regardless of the position of the wing. In addition, may be provided on the movable housing part, a guide pin extending away from the movable housing part in the exit direction and which is designed to engage with a recess in the wing, when the wing is pivoted in parallel position with the frame. Such a guide pin ensures that the movable housing part is moved towards the fixed housing part and aligned with it when the wing is pulled up to the frame. In addition, if a spring element is provided that biases the movable housing part toward the fixed housing part, the angular position of the movable housing part is predetermined even if there is only partial engagement of the guide pin with the wing. Such a rigid guide element is particularly necessary so that, especially in jerky opening or closing movements of the wing relative to the frame, where the inertia of the chain and the movable housing part plays a role, always the desired angular position between the movable housing part and wing is guaranteed. In order to facilitate the engagement of the guide pin with the recess on the wing, the guide pin tapers in the direction of the movable housing part.

It is particularly preferred if the receiving device attached to the fixed housing part and arranged along the pivot axis is arranged on one side of the movable housing part. Seen along the pivot axis on the opposite side may be provided on the fixed housing part further comprises a connection unit with connection contacts for driving the actuator. In particular, connection contacts for a photovoltaic cell and / or a rain sensor and / or an electrical sun visor may be provided on the connection unit. For pivotally mounting the movable housing part to the fixed housing part, a first hinge is preferably provided between the connection unit and the movable housing part, and a second hinge is preferably provided between the accommodating device and the movable housing part.

Such an arrangement aims at a compact design as possible of the actuator, which is required because as extensive as possible insulating elements must be attached to the mounting location of the actuator on the inside of the frame to meet current energy saving requirements. Since it makes sense to make the movable housing part as small as possible and the power supply unit and the connection unit need not necessarily be arranged in the immediate vicinity of the chain or drive unit, power supply unit and the connection unit are preferably formed as part of the fixed housing part.

Another aspect of the present invention relates to a window or door having a frame and a wing, and to an actuator for pivotally driving the wing relative to the frame, the actuator being formed in accordance with any of the previously described embodiments of the present invention.

Then the connection ends 55 the chain 8th with the wing 10 the window or the door connected. If now the closed window to be opened, ie the parallel to the frame extending wings 10 be pivoted relative to the frame, so that the extension levels of frame and sash 10 are no longer parallel, so will the engine 19 the drive unit 21 controlled by a user such that the engine 19 its output shaft 61 rotated. About the transmission 63 , ie via the worm wheel 67 the output shaft 61 and the gear arrangement 69 . 71 . 73 now becomes the sprocket 57 rotated, causing the chain 8th whose chain links 53 with the teeth of the sprocket 57 engage, in the exit direction 51 through the in the movable housing part 7 provided chain outlet opening 47 is moved out. The farther the wing 10 is pivoted relative to the frame from a parallel position, the more the position of the changes on the wing 10 fastened connection end 49 the chain 8th opposite the chain outlet opening 45 , Because the chain 8th perpendicular to the chain plane 41 is stiff, performs the movement of the wing 10 opposite the frame, eliminating the chain 8th also perpendicular to the chain plane 43 is moved, to that the movable housing part 7 opposite the fixed housing part 5 around the hinges 13a . 13b formed pivot axis 11 performs a pivoting movement and always aligns so that the through the guide rail 49 defined chain level 43 and the connection line between the chain outlet opening 47 and the location of the grand piano 10 where the connection end 55 is attached, run parallel. The chain 8th so it is not bent. Will the wing 10 moved back in the direction of a parallel position to the frame, so supports the between movable and fixed housing part 7 . 5 arranged spring element 41 the movable housing part 7 thereby, back to the initial position, ie in a parallel position of the chain level 43 and mounting surface 9 to swing back. For small opening angles between frame and sash 10 engages the guide pin 75 in a recess 77 on the wing 10 and thus ensures a movement of the wing 10 for a given change in the angle of the movable housing part 7 opposite the fixed housing part 5 depending on the angle of the wing 10 opposite the frame.

The supply of the drive unit 21 , especially the engine 19 with electrical power via the power supply unit 15 , The detachable in the cradle 23 or the recess 29 absorbed power supply component 27 supplies DC power to the motor 19 , As a power supply component 27 may alternatively be a power supply 33 with a rectifier or a battery element 31 be used.

Both variants of the Stromversargungsbauteils 27 can equally in the cradle 23 be recorded and by a connection of the recording contacts 25 with the supply contacts 31 with the drive unit 21 be electrically connected. In this way, a user can easily and inexpensively between a power supply 33 and a battery element 35 as a power supply component 27 change if one of the two makes more sense for the current mission.
