Description

The invention relates to an over-rotation to limit the pivoting range of hinged on a wall folding shutter according to claim 1.

Such devices are used primarily in such shutters used between a building opening closing position and an open position to only a limited angle, in particular by only 90 °, are pivotable. The closed building opening is typically a window, but can also be a door, especially a balcony or patio door. In addition to bauästhetischen aspects serves the perpendicular projecting from the wall, especially in some regions of France widespread opening position of the shutters, inter alia, as a sunscreen against lateral sun.

In particular, shutters are opened in this way in the open position on the wall, the individual folding shutters are often in two parts, so that the distance they protrude in the unfolded state of the wall to the outside, only about half of the unfolded length or ., one fourth of the building opening width. In the case of these shutters, the opening position protruding vertically from the wall is sometimes even due to the design.

The over-rotation should basically prevent the open shop on the vertically projecting from the wall opening position also completely folds down by 180 ° relative to the closed position of the wall.

Among other things, such Überdrehsicherungen are known from the prior art, consisting of a simple, fixed stop, such as an attached to the wall wall angle plate, to which the folding shutter rests in the open position and the complete folding of the store against the Wall prevented.

However, such fixed attacks have the disadvantage that the folding shutter can move forward and back unhindered in wind. In addition to unwanted rattling noises, this can cause damage to the folding shutter over time if it hits the angle plate unhindered in the wind. In addition, fixed stops allow the folding shutter to bring only in a specific open position to stop. Between the open position and the closed position of the folding shutter is otherwise - except for the articulation of the folding shutter itself - completely unguided and in particular undetectable.

The object of the present invention is therefore to provide an over-rotation of a folding shutter, which allows a limited and continuously guided, in particular adjustable pivotability of the folding shutter between the closed and open position and further preferably allows a releasable locking of the folding shutter at least in the open position.

This object is achieved by an over-rotation according to claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

The inventive over-rotation is characterized in that to limit the pivoting range of the folding shutter a strut and associated hinge means are provided, by means of which the strut at one end to the wall and the other end of the folding shutter each rotatable and in addition either slidably on wall or folding shutters can be arranged , Such that the folding shutter between the closed position and the open position by a predetermined angle, in particular by 90 °, is limited pivotally.

In accordance with the invention it has been recognized that a continuously guided and at the same time limited pivotability of the folding shutter can be ensured by a moving along strut between folding shutter and wall, which is rotatable at one end and at the other end rotatable and simultaneously displaceable. Since the strut over the entire pivoting range provides a continuous guidance of the folding shutter, can also be achieved with appropriate design of the hinge means that the pivoting range between the open position and closed position of the folding shutter is gradually or even continuously adjustable.

Thus, it is conceivable, for example, in a particular embodiment of the invention that the displaceable articulation of the strut on wall or folding stores by means of preferably step-like locking means or continuously acting or adjustable friction or clamping forces is designed so that the strut in different displacement positions and Consequently, the folding shutter in various intermediate positions between opening and closing position form and / or non-positively fixed.

In this case, the strut can be arranged either on the inside of the folding shutter and according to the other end of the soffit of the building opening. Preferably, however, the strut is arranged on the outside of the folding shutter and at the other end on the wall next to the building opening.

According to a first advantageous embodiment of the invention, a hinge is provided as a hinge means for rotatable arrangement of the one end of the strut on wall or folding shutters. The hinge preferably has a stop means to be fastened to a wall or folding shutter, which is connected via an axis of rotation aligned parallel to the pivot axis of the folding shutter to an end-side connection region of the strut or a connection element arranged end-to-end on the strut.

As a stop means, for example, an angle plate into consideration, which can be attached with one of its legs on the wall and on the other leg, the strut is rotatably mounted about an axis which is aligned parallel to the pivot axis of the folding shutter. It is conceivable, for example, that the rotatably mounted end of the strut, so in particular the connection region or the end arranged on the strut connection element, a simple through hole or a bore which is in engagement with the axis of rotation.

Further, the rotatably mounted end of the strut, so in particular the connection area or the end arranged on the strut connection element, rest on the corresponding leg of the stop means or engage around this mouth or claw-like. In the latter case, the connection region or the end element arranged on the strut can have a slot-like opening or the like.

As a rotation axis, for example, a simple bolt, a mandrel or a through rivet into consideration, each rotatably connect the stop means with the connection area or the terminal arranged on the strut connection element.

In order to compensate for length tolerances and fit inaccuracies, it is provided according to a further advantageous embodiment of the invention that the connection element is arranged adjustable in length on the strut in the longitudinal direction. This can be realized for example by a thread-like attachment of the connection element to the strut or attachment of the connection element to the strut by means of oblong holes.

Analog can also have the particular angle-like stop means on the wall-side leg aligned oblong holes to compensate for vertical or horizontal tolerances in the attachment of the stop means on the wall can.

According to a further advantageous embodiment of the invention is as a hinge means for rotatable and displaceable arrangement of the other end of the strut of folding shutter or wall a parallel to the pivot axis of the folding shutter aligned cylindrical extension, in particular a pivot, provided with a parallel to the pivot axis the folding shutter aligned longitudinal groove in the folding shutter can be brought into engagement. The length of the longitudinal groove typically limits the pivoting range of the folding shutter.

Thus, the longitudinal groove may be formed for example on the lower or upper side of the folding shutter, in which engages the cylindrical extension at the end of the strut from below or above and is guided during the unfolding of the folding shutter. In particular, the longitudinal groove may be formed in profile like an undercut, in which a correspondingly formed head of the cylindrical extension engages positively, so that the strut on the folding shutter in addition to the pivot axis, ie in particular against gravity, is stored captive on the folding shutter.

According to an alternative embodiment of the invention is provided as a hinge means for rotatable and displaceable arrangement of the other end of the strut of folding shutter or wall, a displacement device having a guide element and a sliding element parallel thereto or parallel to the pivoting plane of the folding slide sliding member.

In this case, the guide element on the folding shutter or on the wall can be fixed and the strut end rotatably mounted on the sliding element parallel to the pivot axis of the folding shutter.

Preferably, the guide element is designed as a rail or slide, in or on which the slider is guided displaced. In this case, the displacement device may preferably have a grid displacement mechanism, as it is known from cutter or carpet knives. It is conceivable, for example, that the rail additionally has a locking pattern on the guide surfaces, engage in the correspondingly formed, in particular spring-loaded locking elements on the slider, so that the folding shutter can be positioned in stages between the opening and the closed position in different intermediate positions. In this way, the folding shutter can be adapted to different sunshine angles. In addition, the latching displacement mechanism may also again have releasable locking means to fix the sliding element relative to the guide element in a certain position.

In order to achieve a continuous adjustment in different intermediate position or to dampen the pivoting range of the folding shutter in a similar manner, a frictional, damped displacement can be provided according to a further embodiment of the invention by a suitable choice of Reibpaarmaterialen between the sliding element and guide element.

Also, the sliding member may be formed as a continuously acting, in particular luftdruckbeaufschleses, brake element which is slidably disposed on the example designed as a slide bar or rail guide member, similar to a valve brake on furniture with downwardly opening flaps.

It is also conceivable that the strut is designed as a printing cylinder - similar to the impression cylinder on boot lids of motor vehicles -. In this case, can even be dispensed with a sliding device on wall or folding shutter with guide element and sliding element. The designed as a pressure cylinder strut is then only rotatably mounted at each end rotatable wall and folding shutters.

In order to make the folding shutter space-saving as possible and in particular to allow a flush closure of the folding shutter with the wall in the closed position, it is provided according to a further advantageous embodiment of the invention that the displaceable and rotatably mounted end of the strut relative to its longitudinal direction, especially in the direction of the displacement device is angled.

To limit the pivoting range of the folding shutter, in a further advantageous embodiment of the invention, the guide means comprise two stops, between which the sliding element on the guide element is displaceable. To avoid rattling noises, may also be provided on the contact surface of the sliding element to the stops and / or on the contact surfaces of the stops to the sliding elastic damping elements, such as rubber, spring elements or the like.

To secure the folding shutter in wind, it may be provided according to a further preferred embodiment of the invention, that the slider, preferably on at least one of the stops, by means of latching means or magnetic connection means, in particular in one of the open position of the folding shutter corresponding end position releasably fixed again is. As a result, a releasable locking of the folding shutter is made possible at least in the open position in an advantageous manner.

It is also conceivable that the folding shutter is spring loaded in the open position. For this purpose, the sliding element or the cylindrical extension, for example, with a spring, which preferably acts in the longitudinal direction of the guide element or the longitudinal groove, are subjected to force and pressed against one of the stops. To close the shutters this must then be moved against the spring force in the closed position. In order to hold it there against the spring force, a releasable locking or locking mechanism - similar to the locking mechanism of spring pressure loaded furniture drawers - provided on the other stop, which can be preferably brought into engagement with the sliding element or the cylindrical extension.
