Description

DESCRIPTION

FITTING ARRANGEMENT FOR LIGHT COUPLING

The invention relates to a fitting arrangement with the features in the preamble of the main claim.

Such a fitting arrangement is known from EP 0 443 050 Bl. It serves to open and close a pivotally mounted skylight and has a movable scaffold. The scaffold consists of several mutually movably connected support beams, which are designed as differing L-shaped sheets. This scaffolding training is complex and difficult. It also looks clunky.

Other fitting arrangements in a similar construction are known from DE 10 2006 018 485 B4, EP 1 767 726 A1 and DE 81 31 898.

It is an object of the present invention to show a better fitting arrangement.

The invention solves this problem with the features in the main claim.

The formation of at least some support beams as a tube-like profiles with similar training has the

Advantage that the visual appearance is improved.

In particular, the scaffold has a filigree appearance than in the prior art and interfere with its arrangement in the lid or dome opening less the visual impression.

In addition, the profiles are better and, above all, usable multiple times. The use of similar profiles reduces the construction and cost. In particular, storage and logistics costs can be saved. This saving effect is optimal, if not only similar, but the same shape profiles are used. In the preferred embodiment, all pivotally mounted support beams consist of the same cross-section tube-like profile. It comes thereby a single profile used, which can be purchased inexpensively in correspondingly large quantities and only cut to length for use in the various beam functions. A common part design has particularly high cost advantages.

Conveniently, the formation of one or more, possibly all support beams as straight profiles. This reduces the processing effort and facilitates assembly. This can save costs. Furthermore, it is advantageous if one or more, possibly all profiles on at least one longitudinal side have an opening, which, for example. extends over the entire profile length. This facilitates adaptation and assembly and simplifies the installation of other parts. The training is also useful for a mechanical stabilization and for a cost-saving standardization of the support beams and profiles.

Particularly favorable is a profile which consists of a tubular base body with at least one longitudinal and undercut receiving groove on at least one outer side. This profile can be used several times functionally. The groove can be used on the one hand for receiving guide shoes or the like. Of sliding guides or other guides.

On the other hand, can be done by the groove and a mounting or storage of the profile by means of a pushed through bearing or hinge pin. For this purpose, it is also advantageous if the groove is arranged centrally and has a frustoconical inner contour in cross section.

Furthermore, it is advantageous if the groove bottom by a rear support bar with the opposite wall of the Basic body is connected. As a result, on the one hand, the groove is supported against forces acting from the outside and on the other hand offered a support and guidance for hinge or bearing pin.

The claimed Stützbalkenausbildung can be used for different types of fitting assemblies and scaffolds, the basic structure and kinematics may be the same or similar as in the aforementioned prior art. The invention also relates to a particularly optimized in this respect fitting arrangement that allows a filigree and simple design, a maximum opening angle of the lid or the dome light and thereby with a simple drive, in particular a linear drive, e.g. one

Cylinder, get along. The claimed fitting arrangement has further advantages in terms of stability and functional and reliability. It may also have a locking device, which provides in the closed position for a mechanical locking of the lid or the dome light and thereby relieves the drive. Wind forces or other externally acting forces can be absorbed via the locking device.

In the subclaims further advantageous embodiments of the invention are given.

The invention is shown in the drawings, for example, and schematically. In detail show:

The invention relates to a fitting arrangement (1) for movable cover (2). This can in particular skylights, flaps or other types of closures of building openings or the like. be. The invention further relates to a profile (22), which is particularly well suited for a fitting arrangement (1) of the type mentioned.

FIG. 1 shows a perspective view of a light dome (2) with a fitting arrangement (1). The

Skylight (2) is movable by means of one or more bearings (6) on a substructure (5), for example on a frame around around a roof opening, arranged. In the illustrated and preferred embodiment, the dome light (2) is pivotally mounted by means of two pivot bearings (6) on the frame (5) and can be opened by approximately 180 °. The fitting arrangement (1) serves to open and close the dome light (2) or another type of cover.

The fitting arrangement (1) has a movable support frame (4). This may include a drive (3), but this is not mandatory. The drive (3) is e.g. designed as a linear drive. He can e.g. from a pneumatic or hydraulic cylinder, an electromotive spindle drive or the like. consist. The drive (3) can be present several times. Alternatively, other types and / or arrangements of drives with other kinematics are possible.

The scaffold (4) consists e.g. of several mutually movably connected support beams (8 to 11). One or more, e.g. All support beams (8 to 11) can have a straight shape and longitudinal extent. In addition, further framework components (12, 13, 15) may be present. The latter can e.g. one or more struts (12), one or more support fittings (13) and / or one or more links (15).

The support beams (8 to 11) connected to one another in an articulated and / or displaceable manner can each be arranged individually or according to FIGS. 1 to 5 in a multiple arrangement, eg in the respective double arrangement with parallel beam position shown. The following explanations relate in each case to a single support bar (8 to 11), whereby this also applies correspondingly to the double arrangement or another multiple arrangement. An aspect which is important for the invention consists in the formation of one or more, eg all support beams (8 to 11) as tube-like or tubular profiles. The profile may on one or more longitudinal sides of one or more externally accessible openings (38) in the

Have profile wall. The openings or wall openings (38) may extend over the entire profile length or over one or more subregions of the profile length. It can be arranged distributed in the circumferential direction of the profile a plurality of wall openings (38).

The profiles can be similar to each other. The similarity concerns e.g. the cross-sectional design. In a particularly preferred embodiment, the profiles (22) may not only be similar but even identical in shape. In particular, they can have the same cross-sectional configuration. They may have the same or different lengths.

Another aspect of the invention relates to the formation of the support beams (8 to 11) with a particularly preferred profile shape (22), as e.g. is shown in Figure 6, this being independent of whether the support beams (8 to 11) have mutually identical or identical shape or different profile shapes. These

Aspects of the invention may be carried out with constructive and kinematic arbitrary fitting arrangements (1), e.g. are formed according to the above-mentioned prior art.

In the embodiment of Figure 1 to 5, a particularly preferred fitting arrangement (1) is shown, which has its own inventive meaning and which can also be designed with other and any types of support beams (8 to 11) and other profile shapes. As can be seen from FIGS. 1 to 3, the support frame (4) has a support beam (8) designed as a stationary support element, which extends transversely through the roof or substructure opening and thereby assumes an oblique position. At the higher end is the

Support beam (8) inside the upper edge of the substructure (5) by means of a fitting part and a bearing pin (21) attached. At the other lower end an attachment to a vertical support fitting (13) is provided, which is arranged on the frame inside. This attachment point also has a bearing pin (21).

On the support bar (8), a hook (34) of a subsequently explained locking device (7) is arranged. In the double arrangement shown, the two support beams (8) extend at a distance parallel and take up the drive (3) between them.

On the support bar (8) and / or on the support fitting (13) is another support bar (9) via a hinge (16) rotatably arranged, which is designed as a pivotable drive holder (9) and at its free end about a hinge (17) pivotally a holder for the drive (3), here the cylinder carries. The support bar (9) may also be present in a double or multiple arrangement.

At the upper end of the support fitting (13) a third support bar (10) is rotatably mounted about a hinge (20), which is designed as a pivotable guide and which may also have a double or other multiple arrangement. Between the pivotable drive holder (9) and the pivotable guide (10) a handlebar (15) with end-side joints (18,19) is rotatably arranged. The lower hinge (18) is located between the joints (16,17) of the pivotable drive holder (9). The other Upper joint (19) is arranged on the pivotable guide (10) at a distance from the rear joint (20).

The pivotable guide (10) is in turn articulated and also slidably connected to a support bar (11) which is formed as a lid installation and extends transversely through the lid opening. Here can also be a double or multiple arrangement. The support beam (11) is connected at its ends via suitable fittings with the edge of the lid (2) or the dome light.

The drive (3) is connected to the support bar formed as a pivotable guide (10) via a guide (31), e.g. a sliding guide, rotatable and in the longitudinal direction of

Support beam (10) movably connected. FIG. 4 shows this arrangement. The output member (29) of the drive (3), e.g. formed in the embodiment shown as a piston rod, has a connection (30) which is designed for example as a crossbar and at both ends via the said guide (31) with the support bar (10) is engaged. The drive (3) extends between the parallel support beams (10). In an alternative arrangement with only one support beam (10), a one-sided connection (30) may be present.

The guide (31) has a guide shoe (32) which is rotatably connected to the connection (30) and is axially movably guided in the support beam (10) and whose movement path is limited on both sides by stops (33). The guide (31) may e.g. be a sliding guide. It can alternatively be used as a rolling guide or the like. be designed.

The connection or crossbar (30) cooperates with the one or more hooks (34) of the locking device (7). In the closed position shown in Figure 3 the drive (3) obliquely aligned, wherein the output member (29) and the connection (30) perform an obliquely downward movement, which also has a along the support beam (10) to the bearing (20) directed movement component. As a result, the sliding shoe

(32) pulled against the rear stop (33), wherein the connection (30) is brought into positive engagement with an undercut receiving opening on the hook (34). The hook (34) engages over the connection (30) in the end position. As a result, on the one hand the

Support beams (8,10) locked each other form-fitting manner, so that the lid (2) by force from the outside, e.g. by wind forces, can not open undesirable. On the other hand, the drive (3) is relieved of such force attacks.

To open pushes the extending output member (29) the shoe (32) in the support beam (10) forward to the front stop (33), whereby the locking device (7) is released and then the dome light (2) can be opened.

The support beam (10) is in turn guided longitudinally movable in the two-sided outer support bar (11) on the guide (35). At the front end, the support beams (10) are connected to a cross bar (36) which is rotatably engaged at both ends thereof with a guide shoe (37). The guide shoe (37) is guided axially displaceably in the support bar (11) designed as a lid installation.

FIG. 3 shows the fitting arrangement (1) and the support frame (4) in the closed position. To open the cover (2), the retracted drive (3) is actuated in the aforementioned manner, which, after opening the locking device (7) in the manner illustrated in FIG. 1, acts as a pivotable guide (10). trained support beam rotates about its bearing (6), wherein the drive (3) in turn via its support rotatably supported on the support bar (9). The two by the handlebar (15) coupled support bar (9,10) rotate by the driving action and take the built-in lid support bar (11) with opening of the dome light (2). When closing takes place a reverse movement.

As is apparent from FIGS. 2 and 4, the support beams (8, 11) arranged in the frame opening and in the cover opening can be arranged one above the other in plan view, which also applies to the pair arrangement or multiple arrangement. The other support beams (9,10) are arranged within the support beams (8,11) and in turn can be superimposed in plan view. This also applies to the pair arrangement or multiple arrangement. As Figure 2 illustrates, builds through this design, the fitting assembly (1) and its support frame (4) very narrow and filigree and covers only a small portion of the frame and lid opening. In the closed position, the scaffold (4) may have a small vertical extension and be largely included in the frame area, with only possibly the drive projecting obliquely downwards.

Figure 5 illustrates in plan view an embodiment of the support bracket (13). This may comprise a frame assembly and a vertical support profile (14), e.g. is designed as a U-profile and has with its opening to the center of the lid. On the support profile (14) are the joints

(16,20) for the support beams (9,10) arranged. The joint (20) can be located at the level of the lid edge and is preferably arranged slightly above the pivot bearing (6). As Figure 1 illustrates, one or more struts (12) can also be slanted between them

Support fitting (13) and the support bar (8) may be arranged. In a first embodiment, at least some of the mutually movably connected support beams (8 to 11) are formed as similar, tube-like profiles (22). This improves the visual appearance and is also favorable for the production and assembly costs. The profiles (22) can thus have similar cross-sections, as shown for example in Figure 6 as a possible embodiment. Here, the cross-sectional dimensions of the beam profiles can vary. In the preferred embodiment, all supporting beams (8 to 11) are formed at least as similar profiles (22).

In a further preferred embodiment, at least a part and preferably all of the support beams (8 to 11) movably connected to one another are formed as profiles of identical shape (22). They all have the same profile cross-section with the same shape and the same dimensions. Differences between the support beams (8 to 11) are in the length of the profiles.

FIG. 6 shows a particularly preferred cross-sectional shape of the profile (22). The profile (22) has a tubular base body (23), which preferably has a substantially rectangular cross-section and can have rounded corners. In the embodiment shown, the rectangle sides are of different lengths. In a variant, not shown, they can be the same length, resulting in a square tube cross-section.

The main body (23) has on an outer side a longitudinal opening (38), for example in the form of an undercut groove (24), which is open to the outside. This groove can also be multiple and on several outer sides be arranged. In the illustrated and preferred embodiment, the groove (24) is located on a broad side of the base body (23). Alternatively, it can also be arranged on a narrow side or on a broad and narrow side. Preferably, the groove (24) is arranged centrally on the main body wall.

The groove (24) has e.g. a frustoconical inner contour. This is formed by oblique lateral groove walls (25) and a straight groove bottom (27), which runs parallel to the adjacent broad sides of the base body (23). The groove (24) has a narrowed access opening (26) and thereby forms the undercut shown and in cross-section mushroom-like shape.

The groove bottom (27) is e.g. at the back or bottom by a support bar (28) connected to the base body (23). The support web (28) is arranged centrally on the groove bottom (27) and is aligned transversely to the groove bottom (27). As a result, the groove bottom (27) is supported relative to the side of the base body (23) opposite the opening (26). In the embodiment shown, the support web (28) is formed as a single web. It may alternatively consist of several e.g. consist obliquely arranged webs.

Due to the design shown, the main body (23) has two separate internal cavities. He has also by the groove walls (25,26) a circumferentially closed, dimensionally stable wall.

The groove (24) may alternatively have another, for example rectangular, oval, circular or other cross-sectional shape. The support web (28) may be omitted or designed and arranged in any other way or number. The profile (22) consists of any suitable material. In the embodiment shown, it is a metal, in particular light metal, wherein the profile (22) is formed for example as an extruded profile. Alternatively, the profile material made of plastic or other material, in particular also consist of composite materials.

The groove (24) can serve various purposes, which may differ depending on the application and functional area of the support beams (8 to 11). The groove (24) can, on the one hand, receive a guide shoe (32, 37) or another element of the guide (31, 35) and guide it positively in the profile longitudinal direction. This function is given in the support bars (10,11).

On the other hand, the groove (24) for receiving a bearing ^¬ or hinge pin (21) are used. This is inserted through the groove opening (26) and inserted through an opening which is drilled in the groove bottom (27), by the support web (28) and the opposite wall of the base body (23). The groove (24) and its opening edges facilitate the centering and guiding of the drilling tool. Furthermore, there may be a diameter adjustment at the bolt (21) and at the groove opening (26). The inserted bearing or hinge pin (21) can be supported at the edges of the opening (26) and at the edges of the aforementioned bore and guided in a form-fitting manner. In this case, the width of the support web (28) may be smaller than the bolt diameter, so that a circumferential guidance takes place at three points in the base body (23). The stability of the other areas of the base body (23) and the groove (24) is not affected by the profile design. In particular, there are no distortions of the groove bottom (27) or the groove walls (25). The bearing or hinge pin (21) may have in the mating area a cylindrical shaft with a smooth outer surface and at the ends of a widened head or a thread or the like. Have fastening or clamping elements. The shank may alternatively carry a thread and be designed as a screw bolt. Further, the cross-sectional geometry may be prismatic or otherwise varied.

The receiving function of the groove (24) for a mounting or an articulated mounting can be given in all supporting beams (8 to 11). In particular, the hooks (34) can also be fastened to the support beams (8) via this. Likewise, an end attachment of the support beams (8,11) via screws, clamping bolts or the like. Bolt types (21) is possible. The e.g. Paired support beams (11) in the lid (2) can be fastened or stabilized by end-mounted U-shaped fittings and possibly also in the central region by a further stiffening U-bracket by means of such bolt connections.

Modifications of the embodiments shown are possible in various ways. The structural design of the scaffold (4) and its kinematics can vary. Also, the drive (3) can be structurally designed in another way and also arranged in the support frame (4). Its kinematics can also vary. The cross-sectional shape of the profile or profiles (22) can also be modified with respect to the embodiment shown in FIG. This can be done, for example, by a different cross-sectional configuration of the main body (23) deviating from the rectangular shape or by another shape, arrangement and number of the groove (24). If necessary, the support web (28) can be dispensed with or otherwise formed in a different manner and possibly several times. A support beam (8-11) or a profile (22) may have a curved shape or longitudinal extent. This can be a slight bend or curvature. It may alternatively also be an angling.

The one or more openings (38) in the profile wall need not be grooves (24) of the type described. They can be designed and arranged in other ways. It can be e.g. around linear or punctiform passages, e.g. Through holes, act in the profile wall, which possibly allow a transversely directed insertion or insertion of attachments or fittings. For this purpose, counterbores can be present on the opposite profile side. The openings (38) may also be recesses, in particular line-shaped or punctiform indentations in the profile wall. A sectionwise or pointwise opening arrangement can also be uniform and represent a grid.

Another embodiment relates to a fitting arrangement (1) for a movable lid (2), in particular a dome light, with a movable support frame (4), wherein at least a part of the fitting arrangement (1), eg a part of the support frame (4), as a tube-like Profile (22) is formed. The profile (22) need not form a support beam (8-11), but may have a different design and purpose. The profile (22) may have a hollow body (23) with one or more longitudinally extending, externally accessible openings (38) in the profile wall. The profile (22) may in particular have at least one undercut groove (24) on an outer side, wherein the groove bottom (27) is supported at the back with a web (28) on the base body (23). The fitting arrangement (1) can otherwise be designed as in the previously described embodiment. LIST OF REFERENCE NUMBERS
