Description

The invention relates to a lifting-sliding door or a lifting-sliding window comprising a lifting-sliding sash, a fixed sash and a frame frame, the lifting-sliding sash being adjustable in the frame frame between a raised and a lowered position and in the raised position by means of carriages arranged on the lower sash profile can be moved in a displacement direction on a running rail on the lower frame profile of the frame frame and is guided in a guide rail on the upper frame profile of the frame frame

The sliding sashes of systems designed as lifting and sliding sashes for a window or door often have a relatively high mass.

When moving the sash, especially when pushing the sash from a standing position, a lot of force must be used to open it. Closing also requires overcoming resistance to the inertia of the sliding wing.

Known drives are visible, e.g. in the form of mounting boxes, mounted on the window or door and are shielded with an additional cover, which severely impairs the appearance. The risk of injury during assembly is also increased by visible components that are visible in a disturbing manner. Furthermore, visible components offer more possibilities for manipulation from the outside. Assembling such a drive device also proves to be complex from the known prior art.

Furthermore, power transmission in motorized sliding door systems usually takes place by means of a belt drive, which requires additional components and must be taken into account from the outset when designing and constructing a sliding door system. Retrofitting manual sliding door systems with motorized drives is therefore not possible with the previously known drive solutions or is only possible with great effort.

The object of the present invention is to enable a motorized displacement of a lifting and sliding sash without the drive unit impairing the appearance of the lifting and sliding door or the lifting and sliding window. Preferably, it is also a task to ensure secure engagement between the components causing the motor movement and secure guidance of the lifting and sliding sash in all possible positions of the lifting and sliding sash.

Preferably, the invention should also enable existing lifting and sliding sashes that were previously only manually operated to be retrofitted. More preferably, simple assembly in existing profile shapes should be possible.

This object is achieved in that the lifting-sliding sash has a drive unit in a vertical sash profile, with which a vertically aligned pinion shaft carrying a pinion can be driven, with the guide rail on the upper frame profile between two guide webs, preferably two parallel spaced guide webs Forms a guide groove in which a sliding element lies displaceably in the direction of displacement and in both the raised and lowered positions of the lifting-sliding wing an upper pinion shaft section lying vertically above the pinion lies rotatably mounted in the sliding element (30) and the pinion on a Rack area is in meshing contact with one of the guide webs surrounding the guide groove

Advantageous further developments result from the subclaims.

The drive unit is arranged in such a way that it is suitable for a sliding sash as a lifting and sliding sash, for example for a window or a door. The movable wing has at least two carriages, each with rollers, in order to be moved on a running rail in a direction parallel to the extension of the wing or along a running rail.

For automatically displaceable actuation of the sash, an operating element is preferably provided on a profile of the door or window, preferably on a vertical spar, which controls the drive unit. By activating the operating element, the movable sash can be moved, for example, from a closed position into a position relative to a fixed frame profile and a stationary mounted sash field or another movable sash field. On the other hand, the wing can also be brought into a secure, displaced ventilation position or into a position to form a through opening. The wing is advantageously held movably on the lower frame profile via carriages arranged on the bottom side of the lower wing profile and supported on a running rail.

Advantageously, the drive device for moving the sash comprises a drive motor arranged on the sash side with a pinion shaft driven by it. The connection between the drive motor and the pinion shaft can preferably be done via a gearbox. The pinion shaft with the pinion is positively guided on a rack area arranged on the frame profile and formed on the guide rail.

The guide rail has a dual function in the invention. On the one hand, it guides the sash, in particular it holds it in a direction perpendicular to the direction of displacement, and on the other hand, the guide rail is also part of the drive chain due to the rack area implemented on it.

When the drive motor is running and the pinion shaft is rotating, the pinion rolls with its teeth in the teeth of the rack area and thereby moves the movable wing.

It is preferably provided that the drive unit comprises a drive motor with a vertically aligned motor shaft which is connected directly or indirectly to the pinion shaft. If a transmission is preferably used as an indirect connection, it can further preferably be provided that it exclusively comprises vertical transmission shafts. These constructions mean that the drive unit extends essentially or predominantly in the vertical direction, but occupies a very small installation space transversely and can therefore be accommodated on a vertically extended post of the displaceable wing.

It is particularly preferred if the drive unit is accommodated in a vertically extending receiving space of the wing profile, in particular which forms a profile from the middle section or the center post. Here, the receiving space can preferably be formed by a covered or at least coverable receiving groove in the wing profile, preferably which is open without a cover in the direction pointing away from the glass rebate of the wing profile. Such a receiving groove can be the so-called fitting groove of the wing profile. It is therefore very easy to equip standard profiles with a drive according to the invention, and in particular to retrofit them.

For easy assembly of the components belonging to the drive device, the drive unit with the drive motor is preferably releasably fixed in the movable lifting and sliding wing in a receiving groove in the vertically extending center post. The motor and the preferably adjacent gear are inserted into the recess or receiving groove, for example in the vertical direction or in the direction of the opening of the receiving groove, from an open end of the vertical wing profile, e.g. the center post / center section profile. The torque regulated down in the preferred gearbox is passed on to a rotatably mounted pinion shaft, which is also arranged in the recess of the receiving groove of the vertical wing profile, e.g. of the center post / center section profile.

The pinion shaft is formed from at least two sections, the upper pinion shaft section and the pinion. The upper pinion shaft section is detachably connected to the sliding element, which is loosely attached to the upper pinion shaft section. This plug-in connection creates little frictional resistance between the pinion shaft and the sliding element, and is designed as a fit with radial play. The plug-in connection enables axial movement of the upper pinion shaft section into and out of the sliding element when the lifting and sliding sash is raised and lowered, in particular with an up and down stroke of several millimeters, e.g. approx. 6 mm.

The dimensions are chosen so that the upper pinion shaft section remains at least partially in the sliding element when the lifting and sliding wing is lowered. The sliding element is displaceably guided in the guide rail, which also has the aforementioned rack area, the guide rail being firmly connected to the frame profile.

The maintained operative connection of the toothing between the pinion and the rack area ensures that when the lifting and sliding sash is raised, the pinion engages in the same toothing groove and is not separated from it. A collision or tilting of the pinion when lifting the sliding sash would lead to an unsteady movement, which is avoided according to the invention.

Preferably, the teeth of the pinion and rack areas are each formed by vertically extending tooth elevations and tooth valleys.

The rotating pinion ensures movement on the rack area and thus the movement of the lifting and sliding sash and remains in engagement with the rack area in all positions.

The pinion also fulfills a double function, namely that of the sliding function, which causes the sliding door to open and close, and at the same time a drive function.

More preferably, it is provided that the sliding element is supported in the vertical direction by a stop step, on which the sliding element rests displaceably, which is formed on at least one of the two guide webs. The sliding element preferably remains at a constant height, even when the wing is raised or lowered. This ensures that it remains secure in the guide groove.

The stop step can be formed, for example, by the upper end of the rack region in the vertical direction and/or a step projecting into the interior of the guide groove, preferably which is formed on the guide web which is opposite the guide web with the rack region, in particular vertically below the step A further step is formed, and between the steps a recess which is open and points away from the guide groove is formed, into which a sealing element engages.

The guide rail is particularly preferably fastened in a receiving groove on the upper frame profile of the frame frame, in particular which is open towards the upper horizontal profile of the lifting and sliding sash. The guide rail can thus be designed as an element separate from the frame profile. This also makes it easier to retrofit by replacing existing guide rails with one according to the invention.

Depending on the embodiment, the guide rail can be made in one or more parts. The guide rail is preferably always firmly connected to the frame profile in a receiving groove and has the guide groove mentioned, which is preferably formed by two parallel spaced guide webs. The guide groove ensures precise guidance of the sliding element along and across the guide rail. The sliding element is displaceably mounted in the guide groove in the transverse alignment between the guide webs and preferably in the vertical direction on the upper edge of the rack area or another support step. The sliding element thus stabilizes the travel path and determines and maintains the distance between the pinion and rack, thus performing a positioning function.

In one possible embodiment, the invention can also provide that the sliding element is adjustable in width. Preferably, the width is considered in the direction perpendicular to the direction of displacement of the sliding element. In particular, the play between the sliding element and the guide webs and/or the play between the pinion and the rack can be adjusted.

A preferred embodiment for a guide rail, which is characterized by very economical production, has a rack area that is milled by subsequent machining, for example in plastic or metal. The guide rail or its sub-element can be designed as an extrusion profile.

The invention can also provide that the guide rail is designed in several parts by a guide rail base profile, on which at least one of the guide webs forming the guide groove can be attached as a separate element, preferably releasably attachable, in particular can be inserted into the guide rail base profile.

For example, exactly one of the two guide webs can be fastened to the guide rail base profile as a separate element and the other of the two guide webs can be formed in one piece with the guide rail base profile.

The material combination of the impact partners of the pinion and rack area can consist of metals and their alloys, plastics and metals or just plastics. It is crucial to generate as little material abrasion as possible and to counteract premature wear of the components.

According to the invention, it can therefore be provided in a further development that the material of the rack area is different from the material of the guide rail profile and/or the remaining area of the guide web which has the rack area and is preferably designed as a separate element. For example, the material of the rack area and/or pinion can be made of metal and the material of the guide rail profile and/or the remaining area of the guide web, which has the rack area and is preferably designed as a separate element, can be made of plastic.

The rack area is preferably integral with the guide web. Alternatively, the rack area can, for example, be glued or connected to the guide bar in some other way. The guide web with the rack area preferably consists of a plastic part produced by injection molding or a die-cast part and is essentially I-shaped in cross section.

To simplify assembly, all components of the drive device are mounted in the lifting and sliding sash and in the guide rail before installation.

A correctly movable sequence of the lifting-sliding sash to the frame profile is achieved according to manual or automatic switching specification, in that the drive unit, which is displaceably arranged on the frame profile in the sash, has a fixed position in the horizontal direction with the movable sash. This enables the sash to be adjusted horizontally from a closed position to an open position. In addition, the sash can be transferred to the frame profile into a locked closed position and moved from the locked closed position into a raised position for moving. When lifting the sash and removing it from the running rail or lowering the sash onto the running rail, the sliding element in the guide rail slides along the side stabilizing bars in the guide groove.

The sliding element can preferably be made of a plastic, for example Teflon, or also of a metal, for example sintered bronze.

Preferably, the electrical supply lines to the drive unit can be installed concealed and integrated into the window or door. For this purpose, all contact points form a connecting transmission chain of the electrical current to the individual functional components through control and/or power lines, starting from the power source to the drive device and preferably further to an accumulator.

The invention can therefore generally provide that the drive unit draws its energy from an accumulator which is arranged in the wing, preferably in the same receiving space in which the drive unit is also arranged.

This accumulator can preferably be charged at least in the closed position of the sash by making contacts between contacts on the sash profile and frame profile.

The contact points can preferably also be positioned between the individual functional components. The contact and the stored current of the accumulator are also transferred to the drive motor during the active movement of the wing when it is raised, lowered or moved. When the functional components are arranged in the receiving groove of the drive unit, the control and/or power lines preferably run concealed in the receiving groove. The contact points bridge the power and control signal supply within the receiving groove of the movable sash and from the sash further to the frame profile to the power line towards the power source. The drive unit can usually be installed in the window or door without additional milling.

In this way, an accumulator is advantageously mounted on the lifting-sliding wing, which is in, preferably continuous, electrical contact with the drive device during a movement of the movable wing or when the wing is in a stationary position. Preferably, the movable wing in a resting position, for example in the closed position or in a locked position, receives current bridging to the frame profile via a contactor arranged in an extension of the rack area with a contact point, the electrical contact to a power source arranged on the frame profile or in a building wall for the drive unit .

In a preferred embodiment, the accumulator, referred to as battery for short, is concealed in the receiving groove of the vertical wing profile of the lifting and sliding wing, in particular which comprises the drive, preferably which forms the middle section, close to the drive motor. This ensures a secure power supply from the power source to the drive motor. In addition, the visual appearance of the window or door remains unaffected by the power supply chain, since all components of the drive device are arranged concealed in the window or door.

The invention is explained in more detail below with reference to the drawings.

In 1 is a front view of a closed lift-slide door 100 shown according to the invention. The lifting and sliding wing 1 can be lifted and moved to the right in the raised position. The fixed wing 2 is fixed. Both wings are held in the frame 3 and arranged parallel to each other.

1a shows a sectional view AA in a sectional plane perpendicular to the sliding direction with the lifting and sliding wing 1 lowered and a one-piece guide rail 10 with an integrated rack area 14 on one of the guide webs 12, 12 ', which form the guide groove 13 between them. The sectional view AA cuts the fixed sash 2 with a view of the lifting and sliding sash 1. In the lowered state, the lifting and sliding sash is fixed; this can be any open window position or completely closed.

The components belonging to the drive arrangement are detachably fixed in the movable lifting and sliding wing 1 in a receiving groove of the vertically extending post, preferably which forms the center post in the closed position. The drive motor 50 and the adjacent gear 40 are inserted into the recess or receiving groove from an open end, in particular the upper end, of the vertical center post.

The vertically aligned pinion shaft is formed from at least two sections, here from an upper pinion shaft section 21 and the pinion 22. The upper pinion shaft section 21 lies above the pinion 22. The lower pinion shaft section 23, which lies below the pinion 22, transfers the torque from the transmission to pinion 22. The pinion 22 is at least partially engaged with the rack area 14 even in the lowered position of the lifting and sliding wing 1. In the raised position, the pinion 22 engages with the rack area 14 over a larger area, preferably over its entire axial height.

The upper pinion shaft section 21 is detachably connected to a sliding element 30, which is loosely attached to the upper pinion shaft section 21. The upper pinion shaft section 21 is rotatably mounted in the sliding element 30, but is at least essentially fixed radially, in particular except for a radial play between the outer diameter of the upper pinion shaft section 21 and the inner diameter of the bore in the sliding element 30.

The sliding element 30 is arranged in a guide groove 13 of the guide rail 10. The guide rail 10 is fixed in the fastening groove 3` of the frame profile 3. The guide rail 10 and its guide groove 13 extend in the sliding direction of the sliding-lifting wing 1.

The guide rail 10 is positioned at the correct distance and seat in the upper horizontal frame profile 3 via webs pointing towards the frame profile and engaging in the fastening groove 3 ', e.g., among other things, the positioning webs 11, 11'.

On the side of the guide rail facing away from the frame profile, two guide webs 12, 12' arranged parallel to one another, in particular with different lengths, form the guide groove 13 between them. In this embodiment, one of the guide webs, here the guide web 12, also has a rack area 14. This is arranged at the free end of the guide web 12, with the rack area 14 directed towards the inside of the groove and the teeth of the pinion 22 meshing therein. The guide web 12 can be thickened at the location of the rack area 14 compared to the remaining area of the guide web 12.

The rack area 14 preferably also serves as a support for the sliding element 30 and holds it securely in the guide groove 13. The sliding element 30 is held in the guide groove 13, in particular in a fit with play, and can be moved securely along the guide rail 10 therein.

The guide webs 12, 12 'secure the guide slider 30 perpendicular to the direction of displacement.

1b shows the sectional view AA with the lifting and sliding wing 1 raised and a one-piece guide rail 10 with an integrated rack area 14. The guide rail 10 is preferably extruded in one piece. Preferably, the teeth in the rack area 14 are formed subsequently, for example milled.

The plug-in connection between the upper pinion shaft section 21 and the sliding element 30, which is formed with a fit with radial play, enables an up and down stroke, for example of several millimeters, in particular of approximately 6 mm, when the lifting and sliding sash is raised and lowered.

Since the pinion 22 is at least partially in meshing engagement with the rack area 14, even in the lowered wing position, a permanent operative connection between the pinion 22 and the rack area 14 is ensured. Separating the pinion and the rack area could lead to a misjudgement when re-entering the rack area 14 and, as a result, to the lifting and sliding sash 1 running unsteadily, which is hereby avoided according to the invention.

The pinion 22 is in the raised position of the lifting-sliding wing 1, preferably completely, in engagement with the rack area 14 and can transmit the drive torque generated by the drive motor 50 and the preferably provided gear 40 directly to the rack area 14, so that the lifting-sliding wing 1 on Rack area 14 can be unrolled and moved forward. At the same time, the lifting and sliding wing 1 is guided indirectly via the connection of the upper pinion shaft section 21 with the sliding element 30 along the guide rail 10 in the guide groove 13.

2a shows a sectional view AA with the lifting and sliding wing 1 lowered and a two-part guide rail 10 with an inserted guide web 12 as a separate element. This separate element is thus formed by a rack profile 15. In this embodiment, the guide rail 10 consists of two profiles. The guide web 12, which forms the lateral boundary of the guide groove 13, is not extruded on as in the aforementioned embodiments, but is subsequently attached to a guide rail base profile as a separate element with a rack area 14, i.e. as a rack profile 15, for example inserted into it, which is only used here the other opposite guide web 12 'comprises.

Instead of the extruded guide web 12 with rack area 14 of the previous version, a separate rack profile 15 with molded rack area 14 is used. This variant has several advantages. It is suitable, for example, for making the contact area between the pinion 22 and the rack area 14 possible in a wide variety of material combinations. In addition, with a separate guide bar 12 or. Rack profile 15 with rack area 14 makes it easier to achieve compatibility with differently sized guide rails and frame profiles.

2 B shows the sectional view AA with the lifting and sliding wing 1 raised and the two-part guide rail 10 with the inserted guide web 12 with the rack area 14 2a . The lifting and sliding wing 1 is raised by several millimeters, for example approx. 6 mm, compared to the lowered position. The pinion 22 is in 2a partially engages with the rack area 14 and is lifted up from this position when raised and remains in the same gearing situation, only shifted by the stroke distance. The upper pinion shaft section 21 is pushed further into the sliding element 30 by the amount of the stroke. The sliding element 30 sits loosely on the upper pinion shaft section 21, so that the upper pinion shaft section 21 can be moved up and down in the cylindrical opening of the sliding element 30 in the axial direction of the pinion shaft. The sliding element 30 sits on the pinion shaft 20, guides the lifting and sliding sash 1 precisely and stabilizes the travel path. The pinion 22 ensures locomotion and transmits the drive torque of the motor 50.

The pinion 22 is preferably in the raised position of the lifting-sliding wing, over its entire available height with the teeth of the rack portion 14 engaged and can cooperate with them. The lifting and sliding sash 1 is ready to move and is rolled along the guide rail 10 by the driving pinion 22 for the desired travel path.

3a shows the sectional view AA with the lifting and sliding wing 1 lowered and a likewise two-part guide rail 10 with an inserted guide web 12 ', which lies opposite the guide web 12 with the rack area 14. In this embodiment, the guide rail 10 again consists of two profiles. The guide bar 12 'according to 2a , which forms the lateral boundary of the guide groove 13 and lies opposite the stabilizing web 12 with the rack area 14, is not extruded on as in the aforementioned embodiments, but is subsequently attached to a guide rail base profile, in particular inserted into it. Instead of the extruded stabilization web 12', a guide web 12' is used as a separate additional profile 16, which forms the stabilization web 12' after attachment, or how it works.

3b represents the sectional view AA with the lifting and sliding sash 1 raised and the two-part guide rail 10 with the inserted separate guide web 12 'or additional profile 16.

The function of the guide groove 13 is fulfilled in every embodiment 1 until 3 the intended purpose of enabling movement of the sliding element 30 along the sliding direction.

3c' shows a detailed view of the guide rail 10 in a further embodiment of a separate additional profile 16 for forming the guide web 12 'with a step 18 of the area of the additional profile 16 that forms the groove wall pointing into the interior of the groove 13, so that a correspondingly stepped guide slider is inserted into the groove 13 30 is recordable.

The additional profile 16 can be designed in two steps, so that a receiving space is formed between the steps 18 and 18 ', which extends in the sliding direction and is open in the direction of the groove 13 and which offers space for a seal 17 to be in place even in the raised state, as in 3c shown, to rest without being crushed and to ensure that the pinion shaft runs smoothly. The shape of the stepped additional profile 16 forces the guide slider 30 to have a stepped shape so that both contours lie correspondingly against one another.

The 4a and 4b show isometric views with lowered and raised lifting and sliding sash 1. In the lowered lifting position in 4a the pinion 22 is partially in engagement with the rack area 14 and in the raised lift-slide position 1 in 4b the pinion is in full mesh with the rack area 14.
