Abstract

The motor (70) is connected to the fitting via a gear mechanism (24) so that the motor can be used to lift the window or door (10). The window or door is slid using at least one carriage on its underside.

Description

The invention relates to a lifting slide fitting for a Window or a door with at least one at the Bottom of the frame of the window or door arranged running shoe and a motor drive for Move the window or door.

Sliding windows and sliding doors, which are powered by your Closed position in an open position and back are relocated, are well known. It is located itself the drive motor, which is usually a geared motor is in the area of the upper spar of the frame of the window or the door and drives a toothed belt, on which one Carriage is attached to the frame of the window or the door is attacking. In this way, the sliding sash easy to be moved. The drive motor works for Example with 24 V and is programmable Control provided with which the Shift speed, acceleration and the Move direction is determined. This can be the engine be driven force-controlled, the engine in particular, a stepper motor, so that the end positions (Closed position and open position) can be determined can and the engine according to certain motion schemes can be controlled. These can, depending on the Size and weight of the window or door, be programmed specific to the controller in the control.

There are also lift-and-lift and tilt-and-slide windows and Doors in which the window or door is in front of the door Move raised or before closing must be lowered. These windows or doors are located usually in exterior walls, where the sealing no plays a minor role. In such Lifting sliding windows or doors where the displacement motor occurs, it requires a further drive, for Lifting the grand piano. This is usually on the Outside of the frame put on what the design of the Window or the door bothers. When integrated into the Wing frame is weakened this not insignificant.

The invention is therefore based on the object, the Structural effort for motor-driven Lifting slide fittings reduce and attractiveness Such a motor-driven lifting sliding window or a lift-and-slide door.

This object is in a lifting slide fitting of The type mentioned above solved according to the invention in that the drive via a gearbox with the lifting fitting is connected so that the window or the door with this Drive is liftable.

When Lifting fitting according to the invention serves the Drive on the one hand to move the window or the Door, but he also serves the window or the door to raise. For this purpose, the drive via a gearbox with connected to the lifting gear, so that the driving force on can act on the lifting fitting. The inventive Lift and slide fitting has the significant advantage that the Drive, which is intended to move the wing, can also be used to lift the wing so that no additional drive is required, which is the Appearance of the grand piano bothers by being on the frame is attached. The function of the drive during Lifting fitting according to the invention is thus characterized by the Lifting the sash or lowering the sash extended.

In a preferred embodiment, it is provided that the transmission is a slider crank gear. Another Embodiment provides that the transmission a Gear transmission is. It has to be considered that the Wing may have considerable weight, In particular, such wings can weigh up to 300 kg. To move the wing, however, it only requires a small drive motor with a Transmission gear, which is a gear ratio of, for example, 8: 1, is populated. Such a thing However, transmission would not be enough to the wing to be able to lift. There is an additional for this Thrust crank mechanism required in which linear Movements in rotational movements can be implemented, so that thereby relatively large translations are achieved can. This also applies to gear transmissions in which several gears are arranged one behind the other.

According to the invention, the drive can be a rotary drive or be a linear drive. In general, will be Rotary actuators, in particular geared motors used, where the translation is via a worm gear takes place and drive a timing belt. At this Timing belt is attached to a carriage, over which, like already mentioned in the introduction, the wing is moved. Advantageously, stepper motors are used which are precisely positioned and controllable over the synonymous Positions can be determined.

In a further training is provided that for the Manual operation, a first lifting gear, if necessary is provided with a lock in the frame of the wing. This lifting gear has a nut on which a Handle is attached, over which the lifting fitting is operable. This way, the window or the Door raised manually and then moved.

In a further development, it is provided that the Thrust gear on a second lift gear attacks. The from the slider crank gear in a rotary motion converted sliding movement of the carriage likewise introduced into a nut, so that, like with the first lifting gear, twisting the nut a lifting of the wing causes. That way, the wing can to be raised by motor.

Advantageously, the two lifting gear are the same designed so that the transmission items for both used the first as well as the second lifting gear can be. This reduces the number of for required the fitting according to the invention different components.

In a further development, it is provided that the Lifting gear a pusher with a nut extension and the slider crank gear the follower drives. The drive of the pusher nut over the Thrust gear corresponds to a manual Pivoting a handle, leaving the manual Actuation and motor actuation same components drive.

With preference, the nut extension is via a pivot pin connected to a handlebar attached to a pull rod attacks, which are displaceable behind a faceplate is arranged and in communication with the running shoe. About the drawbar is provided in the running shoe Lifting mechanism operated and the wing raised or lowered. The nut extension and the handlebar form another transmission gear, with a 90 ° rotation the nut into a relatively large one Displacement movement of the drawbar is translated.

It is according to the invention, the pull rod with a Nut extension of the first lifting gear coupled. Will the Wing raised motor, then not only the second Lifting gear but also the first lifting gear mitbetätigt and thereby the handle from its rest position folded in its tilted position, so that the raised Position of the window or door at the position of Handle is recognizable.

With preference the lifting gear are not in their final positions self-locking. Thus, it is necessary, especially for the motor drive, no separate Entriegelungsbeziehungsweise Disinhibition device when fitting to be shifted out of the final position.

To secure the fitting in the raised and shifted position has the slider crank mechanism According to the invention a guide pin, which in the Sliding phase of the transmission movement in a linear setting is guided. This linear backdrop prevents the Wing is lowered, if this is not in the Closed position is located. This means that the Drive movements only in sliding movements be implemented when the guide pin in the linear Scenery is located.

In this case, according to the invention, the window or the door sliding carriage also led in the scenery, which serves as a running rail.

In a further development, it is provided that the Thrust crank mechanism is driven by the carriage. Of the So sled serves both to raise the frame, as to move this too. The coupling or Connection of slides and windows or Door leaf is via the slider crank gear, which on second lift gear attacks.

According to the guide pin during the Lifting phase of the transmission movement via a control link in the linear backdrop introduced. The control slide serves that the wing during the lifting phase his Retains closed position and then postponed can be if it is raised completely. This takes place when the guide pin in the linear Backdrop has occurred.

In a preferred embodiment, the Lifting gear mechanically together e.g. by means of a Drawbar coupled. This causes the lift gear to run regardless of which is operated, synchronously.

Further advantages, features and details of the invention emerge from the dependent claims and the following description, with reference to the Drawing a particularly preferred example in detail is described. It can in the drawing as well as in the claims and in the Description mentioned features each individually or be essential to the invention in any combination.

FIG. 1 shows a door, designated overall by 10, the one fixed wing 12 and a displaceable has stored wings 14. The displaceably stored Wing 14 has on its underside (not shown) Running shoes, which roll on a rail 16 and the a lifting device over which the slidable wings 14 from the in the figure 1 shown position can be raised. In the in the Figure 1 illustrated position seals the displaceable Wing 14 round with the fixed frame and the fixed wing 12 from. On frame 18 of the slidable wing 14 is a handle 20 pivoted, with which the wing 14 is raised can be by the handle 20 by 90 ° in the direction of Clockwise (i.e., in a horizontal position) is pivoted. The raised wing 14 can then in the Figure 1 are moved to the right. The handle 20 interacts with a first lift gear 22, which later will be described in more detail.

In the figure 1 is also a slider crank gear 24th shown, which with a second lifting gear 26th cooperates and which articulated on a carriage 28 is. This carriage 28 is, as shown in Figure 2, guided horizontally displaceable in a rail 30.

As can also be seen from FIG. 2, this is the case Thrust gear 24 from a first link 32 and a second link 34, wherein the handlebar 32 at a Swivel bearing 36 of the carriage 28 attacks and the second Handlebar 34 via a square 38 in a nut 40 of the second lifting gear 26 is used. Finally wear the two links 32 and 34 a guide pin 42, the when moving the carriage 28 after a right with the Arrow 44 indicated movement performs. The downward movement of the guide pin 42 is thereby of a control link 46 supports, so that the guide pin 42 safely after is guided down in the direction of the slide rail 30.

FIG. 3 shows the opened second lifting gear 26, in FIG which the nut 40 is rotatably mounted on which a Nut extension 48 is attached. At this nut extension 48 is a pivot bearing 50, on which a handlebar 52nd is pivotally coupled. This handlebar 52 has a from the second lifting gear 26 outstanding nose 54 at which a pull rod 56 (Figure 5) can be coupled. Becomes the nut 40 on the square 38 of the crank mechanism 24 rotated clockwise by 90 °, then pivots the Nutfortsatz 48 and pulls the handlebar 52nd up.

FIG. 4 shows the first lifting gear 22 in open position Position, this first lifting gear 22 also a Nut 58, in which a square of the handle 20th is stored. This nut 58 also has a nut extension 60 with a pivot bearing 62, to which a handlebar 64th is coupled. This link 64 is also with a Provided nose 66, which protrudes from the lifting gear 22, so that the pull rod 56 can be coupled thereto. This means that a pivoting of the handle 20 also causes a displacement of the drawbar 56. In addition, by inserting a cylinder lock (not shown) the pivoting of the nut extension 60th be blocked, but this is not described here shall be.

If the carriage 28 from the illustrated in Figure 2 Position via a toothed belt 68 (Figure 5), of a motor drive 70 (Figure 1) is driven, in Direction A moves, then the slider crank gear 24th stretched, wherein the guide pin 42 with the arrow 44th traced drawn train passes. The guide pin 42 occurs at the end of the control link 46 through an opening 74 in a linear gate 72, which is formed by the rail 30 becomes. In this linear backdrop 72, the guide pin 42 are moved only in the horizontal direction. The Displacement movement of the carriage 28 therefore results in a linear displacement of the two links 32 and 34 and thus the second lifting gear 26, whereby the wing 14th the door 10 is opened.

Accordingly, a displacement of the carriage 28 in Direction of the arrow Z is a linear displacement of the entire Thrust gear 24 and thereby a shift of the Wing 14 in the closing direction until the door the Closed position occupies and the guide pin 42 via the opening 74 leaves the linear gate 72 and along the control link 46 against the direction of the arrow 44th is pivoted. The slider crank gear 24 takes its End position, as soon as the second link 34 at a stop 76 is present.

The carriage 28 thus undergoes a lifting phase, in which the wing 14 is raised, and a sliding phase, in which the wing 14 is moved. In the lifting phase the guide pin 42 passes through the arrow 44th drawn movement path and in the sliding phase is the guide pin 42 in the linear backdrop 72 or in the rail 30. Since the guide pin 42 the linear backdrop 72 exclusively over the opening 74, it is ensured that the wing 14th during the sliding phase can not be lowered.

The drive 70 thus serves with a single carriage 28 both for raising and lowering the wing 14, as well as its shift.
