Description

The present invention relates to a device for the self-opening and / or closing of a rotary axis rotatable wing, in particular a door closer or a door drive, with a trained for attachment to the wing wing-side component, designed for attachment to a frame, a wall or the like wall side Component and a movable lever assembly, via which the wing-side component and the wall-side component are coupled together such that they are apart by a lever movement or towards each other, so as to open or close the wing.

Such devices are used on doors, gates, windows, skylights and the like to open the respective door or window wing power-operated and / or close. Examples of generic devices are door closers, door drives and window drives.

Door closers are known, for example in the form of overhead door closers and serve to automatically close a door or gate wing after its opening and subsequent release. Door and window drives are equipped with a drive system and therefore able to open and close a rotatable wing motor.

Often, that component which provides the opening and / or closing force, ie the closing body of a door closer or the drive unit of a door drive, attached to the upper edge of the door leaf and one or more articulated levers with a above the door leaf arranged sliding or Coupled guide rail. It may also be that the Sliding or guide rail on the door leaf and the closing body or the drive unit is attached to the frame, the wall or the ceiling. In any case, the lever assembly between the wall-side component and the wing-side component is arranged and recognizable as a separate assembly.
When the door is closed so for a viewer, the three modules "wall-side component", "wing-side component" and "lever assembly" are visible and disturb the room image. To enable a more attractive appearance, door closers and door operators are often offered in different color variants. However, this means that all three components mentioned must be painted in different colors and put in stock. This is associated with a considerable effort. DE19717959A1 discloses a device according to the preamble of claim 1. It is an object of the invention to provide a device for automatically opening and / or closing a rotatable about a rotation axis door, in which the above-mentioned disadvantages are eliminated.
The object is achieved by a device having the features of claim 1.
According to the invention, a cover element is movably mounted on the wall-side component or on the wing-side component, which in a first position at least partially covers a visible side of the lever arrangement and / or the wing and is moved out of the movement path of the lever arrangement and the wing in a second position. With such a cover, the lever assembly can be covered with the wing closed so that it is no longer recognizable as a separate component. Door closer, door drives and the like can thus be better integrated into the room image. Unlike conventional systems, the cover can the Lever arrangement and if necessary even overlap the wing forward, since it can be moved away to open the wing. Due to the cover, it is not necessary to produce the lever assembly in different color variants and to keep in stock.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

According to one embodiment of the invention, the cover element is mounted pivotably about a pivot axis on the wall-side component or on the wing-side component. Another embodiment of the invention provides that the cover is slidably mounted on the wall-side component or on the wing-side component, in particular wherein the displacement track extends transversely to an opening direction of the wing. Depending on the pivot position or displacement position, the cover can cover or release the visible side of the lever assembly.

In the first position, the cover element preferably covers at least substantially completely an air gap formed between the wing-side component and the wall-side component. Covering this air gap by a fixed cover separates, as this would block a lever movement. Due to the mobility of the cover, however, it is possible to bridge the air gap and thus to create a particularly smooth transition between the wing-side component and the wall-side component.

An embodiment of the invention provides that the cover is mounted on the wall-side component and defined in the first position, at least on a front side a flush transition to a housing of the wing-side component or that the cover is mounted on the wing-side component and in the first position defined at least on a front side a flush transition to a housing of the wall-side component. With the front of the cover is meant that side which faces away from the door in the mounted state of the door closer or the door drive. By a flush transition between the cover and an adjacent housing such as the housing of a shutter body or a drive unit, a particularly appealing appearance of the door closer or door drive can be created.

The cover may be designed hood-like, so that it covers that component to which it is movably mounted to several sides. Such a hood-like cover member may have a curved outer side to give the device a particularly appealing design.

According to one embodiment of the invention, at least one front side of the cover element is adapted in terms of its surface texture and color to a housing of the wing-side component and / or the wall-side component. In this way, it can be achieved that a door closer or door drive for a viewer with closed wing acts as a single component. Such a device fits much better in the room image as a device with three separate and clearly recognizable as such individual components.

Preferably, the pivot axis of a pivotably mounted cover member extends in the assembled state of the device at least substantially horizontally. The cover can thus be swung up or down from the path of movement of the lever assembly and / or the wing when the wing is opened laterally.

It is preferred that the cover member has an urging surface which is arranged and formed such that upon opening of the wing, a portion of the lever assembly or the wing presses against the loading surface and thus moves the cover member in the direction of the second position. The cover is thus automatically pivoted when opening the wing or shifted without the need for a special drive mechanism is provided. The production cost is particularly low in this embodiment. In principle, however, it is also possible to move the cover motor - for example, sensor-controlled.

It can be provided that the covering element has a flat cover section with a front side facing away from the wing in the mounted state of the door device and an opposite rear side, wherein the loading surface is formed on the rear side of the flat cover section. This allows a particularly simple construction, since the lever arrangement presses the covering component to a certain extent directly from behind when the wing is opened.

The loading surface may be formed as a sliding surface, d. H. due to the shape, the choice of materials and the surface texture for a slipping of the acting component be particularly suitable. Specifically, the loading surface may be inclined and / or curved relative to an opening direction of the wing. Alternatively or additionally, the corresponding mating surface of the lever arrangement or of the wing may extend obliquely and / or curved with respect to an opening direction of the wing.

A further embodiment of the invention provides that the wall-side component or the wing-side component comprises an elongated hollow profile element which is closed at least one open end by an end piece, wherein on the end piece a pivot pin or a pivot pin receptacle is provided for pivotally mounting the cover. Preferably, both open end faces of the elongated hollow profile element are closed by end pieces with pivot pins or pivot pin receptacles. The provision of an end piece or two end pieces allows a particularly simple storage of the cover on the relevant component. In addition, many common door closers and door operators are equipped with elongated hollow profile elements in the form of sliding or guide rails.

By providing suitable end pieces and an associated cover member such systems can be easily retrofitted with a hinged cover. The pivot pin and the associated pivot pin receptacles can be designed such that a clipping or snapping the cover into the associated end piece is possible. The assembly of the cover is particularly simple in this embodiment.

A further embodiment of the invention provides that the pivot pin or the pivot pin receptacle is arranged asymmetrically with respect to a mirror plane of the end piece and / or that the end piece has a plurality of pivot pins or pivot pin receptacles. This allows the storage of the cover in different positions, so as to accommodate, for example, different types of door closers or door drives.

An inventive device may comprise a damping element which opposes the movement of the cover member a resistance. As a result, a smooth movement of the cover can be ensured. In particular, the damping element may be formed as a rotational damper and interact directly with a pivot pin or a pivot pin receptacle of the cover. This allows a particularly simple construction. In principle, a linear damper could be used as a damping element.

A further embodiment of the invention provides that the cover element is acted upon by a prestressed spring in the direction of the first position. In this way it is ensured that the cover reliably moves into the covering position as soon as the wing is closed. That is, it is prevented that the cover member unintentionally remains in the aside moved position. In certain applications, it may be sufficient to provide for moving the cover member toward the first position solely by gravity. In this case, no separate spring is necessary.

According to a particular embodiment of the invention, the wing-side component is designed as a housing for accommodating a closing mechanism or a drive of the device and the wall-side component as a slide rail for receiving a slider of the lever arrangement, or vice versa. In such a configuration, the cover element can partially or completely cover the slide rail, the lever arrangement and the housing.

The cover can be mounted on two opposite end faces of the slide, in particular articulated, be, so that it surrounds the slide rail in a manner of brackets. This allows a particularly simple structure and also ensures lateral coverage of the slide rail.

The cover element may comprise a central wall section for covering the visible side of the lever arrangement and / or the wing and two lateral wall sections extending transversely to the central wall section, on the mutually facing inner sides of which respective pivot pins or pivot pin receptacles are arranged. Such a cover, which is composed essentially of three flat wall sections, is particularly simple and inexpensive to produce.

In the first position, the cover element can at least partially cover both a visible side of the wing-side component and a visible side of the wall-side component. In particular, it may be provided that a cover element-preferably a hood-substantially completely covers both the wing-side component and the wall-side component. This ensures a particularly appealing appearance of the associated door closer, door drive or the like.

The cover member may pivot about a transverse to the axis of rotation of the wing pivot axis on the wall-side component or on the be mounted wing-side component. This is contrary to a mounting on the upper edge of a laterally rotating wing.

The invention also relates to a cover member adapted for moveable bearing on a wall-side or wing-side component of a device as described above. Existing door closers, door drives or the like can be retrofitted with such a cover to allow better integration into the room image.

In the Fig. 1-7 Partially illustrated door 11 comprises a wall-fixed frame 13 and a relative to the frame 13 about a vertical axis of rotation R rotatable door leaf 15. On the door 11, an inventive door closer 17 is mounted, which is fixed to the door leaf 15 closer body 19 and attached to the frame 13 Sliding rail 21 includes. About a lever assembly 23 - here in the form of a single-arm single lever - the closer body 19 and the slide 21 are coupled together. The lever assembly 23 is coupled in the embodiment shown at one end to a projecting out of the closer body 19 closer shaft 25 drivingly effective and at the other end hinged to a run in the slide rail 21 slider 22 (FIG. Fig. 2-4 ) connected. In the closer body 19, a non-visible locking mechanism is housed, which pivots, for example by means of spring force on the closer shaft 25, the lever assembly 23 so that the door 15 automatically closes after opening and subsequent release. In principle, the closer body 19 could also be attached to the frame 13 and the slide rail 21 on the door leaf 15.

On the slide rail 21, a cover member 30 is pivotally mounted about a horizontal pivot axis S. In the embodiment shown, the pivot axis S thus extends at right angles to the axis of rotation R and parallel to a longitudinal extent of the slide rail 21. The cover element 30 comprises a central wall portion 31 and two transverse to this extending lateral wall portions 33. On the side wall portions 33, the cover 30 is hinged to the two opposite end faces of the slide rail 21. It can be pivoted between a lowered position and a raised position, as will be explained in more detail below.

When the door leaf 15 is closed and the cover member 30 as in Fig. 2 shown in the lowered position, the facing away from the door 15 front side 35 of the slide rail 21 is completely covered by the central wall portion 31 of the cover 30. In addition, the lower region of the central wall section 31 projects beyond the lever arrangement 23 and terminates flush with the closing body 19. Thus, the lever assembly 23 for a viewer standing in front of the door 11 is completely covered by the central wall portion 31 of the cover 30. Between the front side 38 of the cover 30 and the front 39 of the shutter body 19 is a flush transition. How out Fig. 5 shows, the slide 21 act with the hinged thereto cover 30 and the closer body 19 in principle like a single component. This impression is supported by the fact that the central wall section 31 and the front side 39 of the closing body 19 are arched and the corresponding bulges adjoin one another without kinking. Furthermore, the cover member 30 is adapted in terms of its surface texture and color to the closer body 19 to further enhance the impression of a uniform component.

When opening the door leaf 15, the lever assembly 23 presses against the back 40 of the central wall portion 31, whereby this is slowly pivoted upwards ( Fig. 3 ). After the door leaf 15 has reached an opening angle of about 30 °, the lower edge 41 of the central wall portion 31 is as in Fig. 4 recognizable on the lever assembly 23. Upon further opening of the door leaf 15, the lever arrangement 23 slides along the lower edge 41 of the central wall section 31. The cover 30 is in this case completely out of the Movement path of the lever assembly 23 and the door leaf 15 swung out. When the door 15 closes again after being released by the user due to the spring force of the door closer 17, the lever assembly 23 slides in the reverse direction at the lower edge 41 of the central wall portion 31 until the cover 30 again projects beyond the lever assembly 23 and finally flush on Housing of the closing body 19 is present. As a result, the slide rail 21 and the lever assembly 23 are always hidden when the door leaf 15 is closed. Nevertheless, unhindered opening of the door leaf 15 is possible at any time.

At the in 8 and 9 In the alternative embodiment shown, the rear side 40 'of the central wall section 31' has a curved contour 42 in order to allow the lever arrangement 23 to slide more easily onto the lower edge 41 of the central wall section 31 '.

In the 10 to 14 the pivotal mounting of the cover 30 is shown in more detail on the slide 21. The slide rail 21 is according to 10 and 11 formed as an elongated hollow profile element which is closed at the two open end faces 45 by respective end pieces 47. Each of the end pieces 47 has a pivot pin receptacle 49 in the form of a recess such as a blind hole or a through hole. The pivot pin receptacles 49 of the end pieces 47 serve to receive respective pivot pins 50 which are arranged on the mutually facing inner sides of the lateral wall sections 33 of the cover element 30. After insertion of the end pieces 47 in the slide rail 21, the cover 30 can be easily inserted into the end pieces 47, as in Fig. 12 is illustrated. This insertion can be done with slight deformation of the cover 30, wherein due to the elasticity of the cover 30 is a snapping or clipping with a subsequent secure hold.

The pivot pin receptacles 49 are each as in FIG Fig. 10 recognizable with respect to a mirror plane E of the tail 47 arranged asymmetrically. Depending on, whether the end pieces 47 as in Fig. 13 illustrated with zargennah arranged pivot pin receptacles 49 or as in Fig. 14 shown with zargenfern arranged pivot pin receptacles 49 are inserted into the slide rail 21, different arrangements of the cover 30 relative to the slide rail 21. Thus, one and the same arrangement of cover 30 and end pieces 47 are mounted in a different manner to a door closer 17, so that Accordingly, two different variants of door closers 17 can be equipped with the same cover 30. As an alternative to the illustrated asymmetrical arrangement of a pivot pin receptacle 49, a plurality of spaced-apart pivot pin receptacles 49 may be provided in an end piece 47.

FIGS. 15 and 16 show an alternative designed cover member 30 'including an associated end piece 47'. In this embodiment, no pivot pin, but a pivot pin receptacle 53 is provided on the mutually facing inner sides of the lateral wall portions 33. In this pivot pin receptacle 53 engages the profiled first shaft end 55 of a rotary damper 57, which is designed for insertion into the end piece 47 '. The opposite second shaft end 59 of the rotary damper 57, which is also profiled, is received in a receptacle 60 at the bottom of the end piece 47 '. When the cover element 30 'is pivoted, a damping force which inhibits the pivoting movement is generated by the rotational damper 57, as a result of which a smoother movement process is achieved.

In the illustrated embodiments, the cover 30, 30 'pivoted due to gravity in the lower position as soon as the lever assembly 23, the lower edge 41 of the central wall portion 31,31' is no longer supported. In order to strengthen this restoring force or in another installation position also an automatic pivoting of the cover 30, 30 'to allow a spring such. B. be a leg spring integrated into the pivot bearing.

The cover 30, 30 ', not only as in the illustrated embodiments, the slide rail 21 and the lever assembly 23 cover, but if necessary, the closer body 19 and / or the upper edge of the door 15. That is, depending on the size and shape of the Cover member 30, 30 'different designs of the door closer 17 possible.

At the in Fig. 17-21 The cover element 30 "is not pivotable, but displaceably mounted on the slide rail 21. For this purpose, corresponding linear guides are provided on the opposite end sections of the slide rail, which are arranged in Fig. 17-21 are not shown separately. The linear guides are preferably designed as sliding guides. As shown, the displaceable cover element 30 "is formed exclusively by a central wall section 31", that is to say there are no lateral wall sections. In the assembled state of the door closer 17 ', the movement path of the sliding movement is vertical.

In order to press the cover element 30 "upward when opening the wing 15, a run-on slope 70 is provided, which is arranged here at the end of the lever arrangement 23, but in principle could also be arranged at another location of the door closer 17 ' Wing 15 is the ramp 30 as in Fig. 18 shown at the lower edge 41 of the central wall portion 31 "on and the cover 30" is held by gravity and optionally additionally by spring force in the lower end position. When the wing 15 is opened, takes place due to the interaction between the ramp 22 and the back 40 "of the central wall portion 31" in the region of the lower edge 41, a lifting of the cover 30, as shown in the sequence of Fig. 19-21 evident.

Apart from a displaceable instead of a pivotable mounting of the cover 30 "is the in Fig. 17-21 shown door closer 17 'similar to that in connection with the Fig. 1-7 described door closer 17 designed.

For the sake of simplicity, the above description of the embodiments has been limited to a door closer 17, 17 '. However, it is understood that the movable cover element 30, 30 ', 30 "could also be integrated in a door drive or in a window drive, wherein a corresponding drive unit would be provided instead of a closing body 19. All disclosures relating to the exemplary embodiments also apply mutatis mutandis to a door - or window drive.

By providing an arrangement of cover member 30, 30 'and two associated end pieces 47, 47', an existing door closer 17 can be retrofitted with a cover in a simple and fast manner.

The invention makes it possible to integrate door closers, door drives and the like in a particularly visually appealing manner in a room image.
