Description

Title: Actuator for a wing element of a door, a gate, a window or the like

description

The present invention relates to an actuator for a wing element of a door, a gate, a room partition, a window or the like. By the actuating device, the wing element can be moved between two positions, wherein the movement is guided by at least one guide body.

Actuators of the aforementioned type may comprise an electric drive which moves the wing element between two positions. Linearly moving wing elements are often driven by a traction means, which is formed for example by a toothed belt, a chain or the like. Another drive option can be formed by a lifting cylinder, which is operated for example pneumatically or hydraulically. For this purpose, the wing element is connected to a piston rod which can move in and out of a cylinder. A resulting disadvantage is a limited travel, since the lift cylinder has only a limited stroke.

A further actuating device for wing elements may be formed by a linear motor, as is known, for example, from EP 0 671 071 B1. The use of linear motors is technically complicated, with a considerable control effort for driving the stator of the linear motor is also required. Although the effective length of a linear motor is technically not limited, however, there is a considerable technical outlay for wing elements moved along a longer path. In addition, linear motors are used regularly only for linear traverse paths, so that an actuator

The guide body for guiding the movement of the wing element may include floor rails in the floor area or supporting profiles in the ceiling area of a room. Wing elements are usually designed for this purpose with rollers that can roll in a bottom rail or in a support profile. Wing elements of room dividing walls have at least one carriage in which rollers are received, which can roll along the support profile. Furthermore, arranged on the bottom side rollers of the wing elements are known which can extend in bottom rails to guide the wing element both in the direction of movement and in the lateral direction.

It is therefore the object of the present invention to provide an actuating device for a wing element, which overcomes the disadvantages of the aforementioned prior art and has a simple operating principle for moving the wing element along a path of indefinite length and direction.

This object is achieved on the basis of an actuating device 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 at least one driver part is received in the guide body and the actuating device is arranged to move the driver part. The driver part has a magnetic coupling to the wing element, by which the movement along the guide body is transmitted from the driver part to the wing element for its actuation or movement. The invention is based on the idea that the driver part is driven in the guide body in the direction of movement of the wing element. The transmission of the movement of the driver on the wing member is formed by a magnetic coupling. In comparison with a linear motor, it should be mentioned that no magnetic field traveling in the direction of movement of the wing element is formed, but a magnetic driver part is set in motion in order to move the wing element by means of a magnetic coupling. The guide body for receiving the driver part can take any shape, so that the guide body can assume an open, a closed or other shape and, for example, is arranged on the ceiling side or bottom side to the wing element. If the driver part is set in motion, there is an offset to the wing element, through which the wing element is pulled along on the basis of the magnetic coupling. As a result, the wing element can be moved between the two positions, for example between an open position and a closed position.

It is advantageous that the guide body is designed as a guide tube, wherein the driver part is guided longitudinally movable in the guide tube. The guide tube may have a round, elliptical, square or square cross section, and is not limited to any cross-sectional geometry. The guide tube defines the direction of movement of the wing element, which is preferably guided on the outside of the guide tube. On a guide body several wing elements can be guided longitudinally movable. Each guide element is associated with at least one driver part, so that a plurality of driver parts inside and outside the guide tube is guided longitudinally movable. After a further development of the actuating device this is adapted to act on the interior of the guide tube with a pressure medium, wherein the driver part against the inner wall the guide tube is dynamically sealed by means of at least one sealing element. By acting on the interior of the guide tube with a pressure medium, the driver part can be set in motion. The interior of the guide tube is thereby divided by the driver part into a dynamically limited by a first end face of the driver part pressure chamber and a second end face of the driver part dynamically limited by a second pressure chamber. By pressurizing the interior, the first or alternately the second end surface of the driver member is pressurized, whereby the driver member is moved in the direction of movement. According to this embodiment, the actuating device is designed as a hydraulic or pneumatic actuator, wherein the movement of the driver part can also be generated mechanically. For example, the driver can be moved within the guide tube by a traction means such as a belt, a chain or the like, while maintaining the magnetic coupling between the driver and the wing member, the driver part are also moved by a mechanical connecting means such as a lifting rod and the like within the guide body can.

If the first pressure chamber is pressurized, then the driver part moves in a first direction, which may relate, for example, to the opening direction of the wing element. If the pressurization of the first pressure chamber is stopped and the overpressure can flow off in the first pressure chamber, the second, opposite pressure chamber can be simultaneously acted upon to act on the second end surface of the driver part. As a result, the driver part is reversed in the direction of movement in order, for example, to transfer the wing element into a closed position. By this alternating pressurization of the guide body is a reciprocating motion of the driver part and borrowed the wing element along a non-limited path either linear or curved possible.

According to a further embodiment of the actuating device, the guide tube has pressure medium connections arranged at the end, which comprise at least one pressure medium inlet and at least one pressure medium outlet. About the pressure medium inlet pressure medium is introduced into the guide tube, whereas the venting of the interior of the guide tube is made possible via the pressure medium outlet. The pressure medium connections can be introduced into end elements used on the guide tube closure elements, which are screwed to the guide tube, for example, glued, caulked or soldered or welded. According to a further advantageous embodiment of the actuating device, the wing element has at least one coupling body, which serves to interact with the driver part and in particular is designed as a magnetic roller holder. The wing element may be guided over at least one carriage along the guide body, wherein the carriage comprises at least two rollers, which are arranged on the carriage. The carriage and the roller holder can form a common component as a result. Preferably, two rollers are provided on a carriage, wherein more preferably the wing member has two carriages, which are guided longitudinally either in a cover-side mounted support profile or a bottom side provided guide rail. The rollers roll off in corresponding guide receptacles in the support profile or in the bottom rail. Particularly preferably, the rollers roll on the outside of the guide body.

The guide body may have a curvature, so that the wing element as a door leaf performs a bow or circular sliding movement. Consequently, the door may be formed as a curved or circular sliding door. In order to allow longitudinal movement of the driver part in the curved guide tube, the shape of the driver part can be adapted to the curvature of the guide tube. The guide body can have a cylindrical shape or a degenerate cylindrical shape with a curved center line for adaptation to a curved guide body, wherein the driver part can also be designed as a ball or egg-shaped in order to achieve line contact with the inner wall of the guide tube and jamming of the driver part avoid.

If the wing element is designed as a door leaf, as a gate leaf, as a wing element for a room dividing wall, a window or the like, this extends regularly in the vertical direction in a room and / or a wall of a building, wherein the guide body is either upper side and / or lower side is arranged to the wing element. The guide tube may be covered by cladding elements, or appear as a design element of the actuator room side in appearance. In particular, the guide tube can be used at the end in wall or lining elements, so that only the free section of the guide tube extends through the space.

On the guide body can be provided on the outside tread portions, which are integrally formed with the guide body or arranged on this. On the tread portions, the rollers of the carriage can roll to accommodate the wing element. The tread portions may be spherical and form both a vertical guide and a side guide of the wing member. It is further provided that the driver part is designed as a permanent magnet or at least has a permanent magnet. The permanent magnet may be diametrically or axially magnetized, or Driver part has a plurality of permanent magnets, which are preferably arranged on the outside, to form a small distance to the outside of the guide tube arranged coupling body. It is further provided that the carriage is annular and at least partially surrounds the guide tube. The resulting reduced distance between the magnetic driver and the annular carriage increases the magnetic coupling, so that higher forces can be transmitted. Between the carriage and the guide tube, a rolling body assembly may be arranged in the manner of a ball guide sleeve, wherein also a sliding bearing arrangement may be provided.

Damping valves and / or check valves can be arranged in the pressure medium inlet and / or in the pressure medium outlet. In the pressure medium outlet, a pressure relief valve is preferably provided, so that at high pressure of the pressure medium, a discharge of the pressure medium takes place. Thus, damage in the actuator can be prevented. A movement damping of the driver can be achieved by the outflow of the pressure medium from the vented portion of the interior of the guide tube is throttled, while the second interior is pressurized. For example, the pressurization of an interior part can be carried out completely up to a maximum pressure, so that the movement of the driver part is produced only by controlled venting of the opposite interior part. In addition, it is possible to perform an emergency stop by activating a check valve that stops bleeding an interior part. The externally connected lines or the line sections in the closure elements preferably comprise check valves, so that the pressure medium can flow out of the tube exclusively through inlet lines and out of the tube exclusively via outlet lines. Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS. It shows:

Figure 1 shows a schematic side view of an actuator 1 according to an embodiment of the invention for a wing element 10, which is designed as a door leaf or as a wing of a room partition. To guide the wing element 10, a guide body 11 is arranged, which is designed as a guide tube 11. To guide the wing element 10 along the guide tube 11, there are two running wheels. provided gene 21, where the wing member 10 is attached. The guide tube 11 is arranged on the upper side of the wing element 10 and can run in or under a ceiling of a room. The guide tube 1 1 is shown running simplistic just, it may also have one or more curvature / s.

Within the guide tube 1 1, a driver part 12 is received. This is guided longitudinally movable in the guide tube 11. At the end, the guide tube 11 has pressure medium connections, on the one hand a pressure medium inlet 19 is arranged for the inlet of a pressure medium in the interior of the guide tube 1 1 and on the other hand, a pressure medium outlet 20 for venting the interior of the guide tube 1 1 and the outlet of the pressure medium. If the interior of the guide tube 1 1 is pressurized via the pressure medium inlet 19 with a pressure means 13 not visible here, then the driver part 12 is pressurized via an end face and moved in the longitudinal direction of the guide tube 11. The driver part 12 is designed as a magnet or has at least one permanent magnet. As a result, a magnetic coupling to the carriage 21 is produced, so that a longitudinal movement of the driver part 12 in the direction of the guide tube 11 causes entrainment of the carriage 21 in order to move the wing element 10 back and forth between at least two positions.

FIG. 2 shows a detailed view of the arrangement of the driver part 12 in the guide tube 11. The driver part 12 has a first end face 15 which delimits a first pressure chamber 16 within the guide tube 11. Opposite, the driver part 12 has a second end face 17, which limits the opposite second pressure chamber 18 within the guide tube 11. The end of the guide tube 11 is closed by a closure element 27 which is screwed by way of example via a thread in the end side of the guide tube 1 1. In the closure element 27, a pressure medium inlet 19 and a pressure medium outlet let 20 be exemplified. Via the pressure medium inlet 19, a pressure medium 13 can reach the first pressure chamber 16 in order to pressurize the first end surface 15 with a pressure. In order to provide an improved function of the preferably pneumatic movement of the driver part 12, this is sealed against the inner wall of the guide tube 11 via at least one sealing element 14. The sealing element 14 may consist of at least one and preferably a plurality of O-rings. In particular, a lubrication in the form of a grease or oil may be provided which improves sliding of the driver 12 against the inner wall of the guide tube 11 and at the same time produces a sealing effect.

Further, rollers 22 and 23 are shown, which are rotatably received via roller shafts 30 and 31. The rollers 22 and 23 roll on the outside of the guide tube 11, for example.

FIG. 3 shows a further embodiment of the actuating device according to the invention with a guide tube 11 on which running surface sections 25 and 26 are integrally formed. The tread portions 25 and 26 are made spherical and serve as a rolling surface for the rollers 22 and 23 which are movably received on the roller axles 30 and 31. In order to illustrate the magnetic coupling between the driver part 12 and a coupling body 24 (not shown in greater detail in FIG. 3), FIG. 4 shows a schematic view of the coupling body 24.

FIG. 4 shows a schematic view of the arrangement of the coupling body 24, which extends around the guide tube 11. The guide tube 11 is shown from the viewing direction of the closure element 27 arranged at the end, wherein the coupling body 24 serves as a roller holder 24 in order to place the first roller 22 on the upper side and the second roller 23 on the underside. increase. Within the guide tube 11, the driver part 12 not shown is arranged. Due to the overlapping arrangement of the coupling body 24, a magnetic coupling is achieved, which is sufficiently strong to cause movement of the coupling body 24 and the wing element 10 arranged thereon by a movement of the driver 12.

Figure 5 shows another embodiment of a carriage 21, which serves as a coupling body 24 and the guide tube 11 surrounds annular. Between the carriage 21 and the guide tube 11 shown from the direction of the closure member 27 is a Wälzkörperanordnung 28, which may be performed in the manner of a ball bearing sleeve 28 or a ball screw 28 and the carriage 21 movably supports on the guide tube 11, in turn, the wing element 10 move - lent to the guide tube 11 to order.

FIG. 6 shows a further embodiment of the bearing between the carriage 21 and the guide tube 11, which is shown from the direction of the closure element 27. The bearing is designed in the form of a slide bearing arrangement 29 which completely encloses the guide tube 11 and forms a bearing between the carriage 21 and the guide tube 11.

The invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. All of the claims, the description or the drawings resulting features and / or advantages including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations. In particular, the drive member 12 is not limited to a cylindrical shape, and may be executed barrel or ellipsoidal. This makes it possible that the curvature of the guide tube 11 can change and yet the drive function is maintained, since the seal between the drive part and the inside of the guide tube 11 compensates for the changes in the curvature of the interior. The embodiment of the rollers 22, 23 between carriage 21 and guide tube 11 and the embodiment of the rolling or sliding bearing between the carriage 21 and the guide tube 11 are mutually interchangeable with respect to their respective features. The wing member 10 may be additionally guided in a bottom rail at a lower edge, for example by means of one or more sliders, whereby the tilting safety of the wing member 10 is increased. In this case, a suspension by means of point holders is possible, wherein the wing element 10 can be used as a whole glass wing element, in particular due to the aesthetic effect.
