Description

CH 711 522 B1

Description: The present invention relates to a device for the automatic actuation of a wing of a lift and slide door.

Lifting-sliding doors are well known. Lift-and-slide doors have a sliding wing that has to be raised, at least before it can be pushed in a horizontal direction from a closed position. When closing, the sash hits a door frame and is then lowered again. This has the advantage that a good sealing effect can be achieved in the lowered position and a displacement in the raised position is possible without too much effort. Lift and slide doors are used, for example, as glazed patio doors or balcony doors. In the following, the use of the term lift-slide door is intended to mean a lift-slide window operated in the same way. For the device discussed below, it is not important whether it is a door (in the sense of a walk-through passage) or a window.

Moving with little force is usually achieved in that the wing has a carriage with at least one roller. The carriage is installed on the lower edge of the wing and firmly connected to the wing. The roller runs on a rail for sliding. The roller can be raised relative to the carriage, which causes the wing to lower in relation to the rail. The roller can be lowered compared to the carriage so that it supports the weight of the wing on the rail and the wing is raised. Manually operated lift and slide doors are raised, for example, by pivoting a handle. Then the wing can be moved horizontally by pushing the handle. Carriages and mechanisms for carriages of lifting and sliding doors, with which a plurality of rollers can also be raised or lowered at the same time, are well known.

Automatically operated doors and windows are also known. A certain difficulty in the automatic actuation of a lift and slide door is that two movements have to be automated, namely lifting the lift and slide door and moving the lift and slide door. In order to simplify and increase the reliability and the space requirement, it is desirable to drive both movements with one motor unit.

From the patent specification EP 1 507 059 B1 a lift and slide fitting is known which accomplishes both the lifting and the displacement of a lift and slide door with a single motor drive. This lift and slide fitting has, among other things, a motor drive for moving a slide, a sliding crank mechanism and a lifting gear. In the closed position of the door, a linear movement of the slide is translated into a rotational movement by the push crank mechanism. The multi-part lifting gear is actuated with this rotational movement. The lifting gear is connected via a pivot pin to a handlebar that engages a pull rod. The pull rod is connected to a running shoe which is arranged on the underside of the wing of the door. By actuating the lifting gear, the running shoe can be pressed down and the door can be raised. After the door is raised, the door can be moved by continued linear motion of the operator. The door is closed in the opposite direction, with the door being lowered at the end of the sequence.

The object of the present invention was to provide a simplified drive for lift and slide doors.

This object is achieved according to the invention by a device for automatically actuating a wing of a lift and slide door with the features according to claim 1.

The device according to the invention is a device for automatically actuating a wing of a lift and slide door, with

a carriage with at least one roller which can be raised and lowered relative to the carriage and is designed to be arranged on a lower edge of the wing,

an actuating fitting which can be guided in the wing and is operatively connected to the carriage for actuating the raising and lowering of the roller relative to the carriage,

- an engine unit,

- A carriage, guided by a linear guide for horizontal arrangement above the wing and driven by the motor unit, characterized in that the device

- A toggle lever with a shorter and a longer leg and with an axis of rotation, which is designed for stationary arrangement with respect to the wing, and

CH 711 522 B1 has a rod connecting the slide and the longer leg of the toggle lever in a force-transmitting manner, and the shorter leg of the toggle lever and the actuating fitting are connected in an articulated manner.

The toggle lever translates a horizontal linear movement of the carriage into a substantially vertical linear movement of the actuating fitting, whereby the roller is raised or raised relative to the carriage. is lowered. Due to the fixed axis of rotation of the toggle lever in relation to the wing, the movement of the slide can also be converted directly into a displacement of the wing. The device according to the invention thus makes it possible in a particularly simple manner to automate both movements required for the actuation of a lifting and sliding door with a single motor unit.

The articulated connection between the shorter leg of the toggle lever and the operating fitting can be implemented directly between these two elements by means of an axis. The articulated connection can for example additionally comprise a rod which is connected to the actuating fitting and the shorter leg of the toggle lever in one joint each. A simple and robust design of a joint can be formed in a fork-shaped end section of the rod with an axis running across the fork.

Compared to most of today's motorizations for lifting and sliding doors, which usually have two motors, namely one for lifting and one for pushing, the device according to the invention stands out advantageously in that no superordinate regulation for two individually controlled motors is needed. In addition, it is avoided that an elaborate and expensive power supply has to be brought onto the sliding sash, as is necessary for a lifting motor.

Further embodiments of the invention result from the features of claims 2 to 10. The invention also relates to a lift and slide door according to claim 11 and embodiments of the lift and slide door with features according to claims 12 to 13.

In one embodiment, a fitting extension consisting of at least two parts and adjustable in length connects the shorter leg of the toggle lever and the actuating fitting in a force-transmitting manner. Such a fitting extension can be adjusted to the length appropriate to the height of the wing and the exact position of the toggle lever when mounting the wing.

In one embodiment, a first part of the fitting extension has a recess for a positive connection with the actuating fitting, in particular a recess with a serrated contour.

The exact shape of the recess can correspond to a standard shape, such as is used to connect actuating fittings with known, manually operated handles. This makes subsequent retrofitting to automated actuation of a lifting and sliding door with a device according to the invention easier. A serrated contour enables fine adjustment of the distance between an upper end of the operating fitting and the articulated connection to the toggle lever.

In one embodiment, part of the fitting extension has a number of equally spaced pins and another part of the fitting extension has a number of holes at intervals corresponding to the pins.

This fitting extension allows a rough adjustment of the length in steps that are predetermined by the spacing of the holes or pins.

In one embodiment, part of the fitting extension has a first row of holes evenly spaced apart by a first distance and having the same diameter, and another part of the fitting extension has a second row of holes which have the same diameter as the holes in the first row and which are spaced apart by a second distance, the second distance being shorter than the first distance, wherein an articulation axis is provided for insertion through a hole from the first row and a hole from the second row.

The fitting extension can consist of other parts, e.g. Poles to be executed. The rods can be equipped with several holes, but the same hole diameter. In the embodiment just described, the hole spacings of the first rod are uniform and those of the second rod are also uniform, but somewhat shorter than those of the first rod. By pushing the joint axis at different positions of the hole pairings, different lengths of the extension result. By repositioning the joint axis in the adjacent holes, a fine stone setting is made possible.

In one embodiment, the rotational axis of the toggle lever, which is fixed with respect to the wing, is mounted in a bearing block attached to the upper edge of the wing.

A fine adjustment of the position of the axis of rotation of the toggle lever can be achieved by placing shims under the bearing block. The provision of a bearing block attached to the upper edge of the wing also makes it easier, in particular, to retrofit an existing wing of a lift-and-slide door to automatic actuation.

CH 711 522 B1 [0022] In one embodiment, the device has a guide cam arranged on the toggle lever and a guide rail for the guide cam.

Such a guide cam can in particular be attached to the longer leg of the toggle lever, in particular at the point where the rod engages the toggle lever. The guide rail can guide the guide cam so that the door cannot be accidentally lowered in the sliding area. The guide rail is stationary with respect to the non-moving parts of the lift and slide door, in particular with respect to the door frame. For positions of the sash close to the door frame, the movement of the toggle lever necessary for lowering the sash can be made possible by an upwardly curved course of the guide rail. When the door wing is opened, such an arrangement of guide cams and guide rails ensures that the wing is raised completely before it is moved.

In one embodiment, the carriage engages in a form-fitting manner in a linearly driven element of the motor unit.

This embodiment can be implemented, for example, in such a way that the slide is positively connected to a toothed belt or chain drive which runs via a pinion driven by the motor. The motor unit can also be a commercially available motor unit with a linearly moving driver. In this way there is an easy-to-use interface to the slide.

Another embodiment has a remote control for the motor unit.

The signal transmission of the remote control can take place for example by means of electromagnetic waves, in particular by infrared, visible light or radio waves. The control elements of a remote control can be attached to a suitable location regardless of restrictions in the cabling. In applications where the automation of the lift and slide door is retrofitted, this flexibility in attaching the controls is particularly useful.

A further embodiment comprises an energy store that can be operatively connected to the motor unit, in particular an accumulator for electrical energy.

Such an energy store allows the lifting and sliding door to be opened or closed even when the external power supply to the motor unit is interrupted.

For absolute emergencies, the carriage can be mechanically separated from the drive unit and thus the wing can be closed.

The features of the embodiments can be combined as desired, provided that they do not conflict with each other.

Within the scope of the invention is also a lift and slide door with a device according to the invention for the automatic actuation of a wing.

[0033] In one embodiment of the lifting and sliding door, the wing has a first locking element which is operatively connected to the actuating fitting, and a door frame is fixedly connected to a second locking element, the first and second locking elements being in the closed position of the lifting Interlock sliding door.

The first locking element can be, for example, a locking hook which engages in the door frame in the closed position and which is operatively connected to the actuating fitting. In this case, the second locking element can be a locking plate which is firmly connected to the door frame. The locking hook can be moved by the actuating fitting over a greater height difference than the height difference between the raised and lowered position of the wing. This ensures a secure hooking. The second locking element can, for example, also be a locking bolt mounted on the door frame, which interacts with a first locking element in the wing for locking the lift-and-slide door.

In one embodiment, the lift-and-slide door has a running rail arranged below the sliding wing, the running rail being arranged in a recessed manner.

[0036] The running rail serves as a guide and support for the running roller. It can be arranged in a door sill or recessed in the floor. The recessed arrangement ensures that the highest edge of the running rail runs below the floor surface. This means that the running track does not constitute an obstacle, particularly for users of a wheelchair.

Exemplary embodiments of the present invention are explained in more detail below with reference to figures. Show it

Fig. 4 parts of a multi-part fitting extension, each a variant of a multi-part fitting extension in Fig. 4.a and Fig. 4.b.

In Fig. 1, the drive according to the invention for the automatic actuation of a sliding leaf 20 of a lift and slide door is shown schematically in the closed position. A motor unit 1 is operatively connected to a carriage 2. The carriage 2 runs, here indicated schematically by wheels, on a linear guide. The motor unit 1 is operatively connected to the carriage 2, so that the carriage can be driven in the horizontal direction. The active connection is shown by a dash-dotted line. A double arrow next to the sled shows the possible movements of the sled. A rod 5 engages the carriage 2 and the longer leg (3) of the toggle lever 3. The toggle lever can be rotated about an axis of rotation 7. Due to tensile forces and pushing forces in the rod 5, the position of the axis of rotation 7 can be shifted in the horizontal direction and also deflected via the toggle lever, a force can be exerted on the actuating fitting 4 via the shorter leg (3 ') of the toggle lever. This force acting on the operating fitting 4 also has, in particular, a vertical component. The force is transmitted through an element articulated at two ends. An articulated connection 6 exists at the transition to the operating fitting

4. The actuating fitting 4 is operatively connected to the carriage 21. The roller 22 can be lowered by actuating the actuating fitting 4 relative to the carriage 21, so that it is supported on a running rail 23 shown in broken lines here to facilitate the displacement of the wing. The roller 22 can be raised so that the wing rests on its bottom edge on the floor or a door sill. A bearing block 13 is attached to an upper edge of the wing. The axis of rotation 7 is mounted in this pedestal. A door frame 24 shown in broken lines forms the end stop for the sliding movement of the leaf 20.

Fig. 2 shows schematically the functional principle of the device according to the invention in three stages of a lifting and sliding process of a wing. For the sake of clarity, only an upper left corner of frame 11 and glass 12 of a wing is shown together with a part of the elements of the device according to the invention. To help orientate and understand linear movements across all three sub-figures, dash-dotted auxiliary lines L1, L2 and L3 are drawn in the sub-figures. A guide rail 14 is shown in the three sub-figures. It has a course which is suitable for guiding a guide cam 17 attached to the longer leg of the toggle lever. The guide rail 14 does not move with the wing.

Fig. 2.a) The wing is in the closed position. The point of attack 16 of the actuating fitting is in its lowest position. In this position the wing is lowered and cannot be moved.

Fig. 2.b) The point of attack 15 of the rod 5 on the (not shown) carriage is further shifted to the right. The toggle lever redirects this movement into an upward movement of the operating fitting. So the point of attack 16 of the actuating fitting is in a higher position than in Fig. 2.a. This allows the rollers in the carriage to be lowered. The horizontal position of the wing is unchanged compared to Fig. 2.a.

Fig. 2.c) The point of attack 15 of the rod 5 on the carriage is shifted further to the right than in Fig. 2.b. The point of attack 16 of the actuating fitting has reached its highest position. The displacement of the slide to the right causes a displacement of the wing by the action of the tensile force in the axis of rotation 7.

In this position, the guide rail 14 prevents an upward movement of the guide cam 17. This prevents the wing from being inadvertently lowered.

3 shows an embodiment of the device according to the invention. In addition to the features already discussed for FIG. 1, here is a fitting extension 8 which extends the operating fitting 4 and ensures the articulated connection to the shorter leg (3 ') of the toggle lever , The fitting extension is multi-part and adjustable in length. An accumulator 31 can be connected to the motor unit via a switch. It serves as an energy store for electrical energy and enables the wing to be opened and closed in emergency operation.

Fig. 4.a) shows a perspective view of parts of a multi-part fitting extension and a possible interface to an actuating fitting 4. The individual parts are shown lying next to each other in the non-assembled state. A part 8 'of the fitting extension has a row of pins 42 which are evenly spaced apart. These pins fit into the corresponding holes 43 in the second part 8 of the fitting extension. One part 8 'also has a recess with a serrated contour 41, which is used for a positive connection with the actuating fitting 4 shown next to it. The serrated contour allows a fine adjustment of the relative position of the operating fitting 4 and part 8 '. The second part 8 also has a hole 44. At the position of the hole 44, a joint can be formed by means of an inserted joint axis 47, e.g. directly to the articulated connection with the shorter leg of the knee lever or with another rod. In the case shown here by way of example, the adjacent element (the shorter leg of the toggle lever or the further rod) has a fork-shaped end for pushing through a joint axis 47.

Fig. 4.b) shows a perspective view of parts of a variant of a multi-part fitting extension. In a departure from the multi-part fitting extension shown in FIG. 4.a, the second part 8 here has a plurality of holes. The other part 8 of the fitting extension also has several holes in order to achieve fine stone adjustment

Enable CH 711 522 B1. The hinge axis 47 is inserted through a pair of holes, one from the first row 45 of holes and one from the second row 46 of holes.
