Description

The invention relates to an over-rotation lock for limiting the pivoting range of a folded sliding shutter hinged to a wall according to claim 1.

Such devices are primarily used in such folding shutters, which are pivotable between a position closing a building opening and an open position by only a limited angle, in particular by only 90 °. The building opening to be closed is typically a window, but may also be a door, in particular 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 Faltschiebeläden be unfolded in this way in the open position on the wall, the individual folding shutters are 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 a quarter of Building opening width corresponds. In these Faltschiebeläden the vertically projecting from the wall opening position is sometimes even due to design.

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

From the state of the art, inter alia, such Überdrehsicherungen are known, which consist of a simple, fixed stop, such as an attached to the wall wall angle plate, against which the Faltschiebeladen rests in the open position and prevents complete folding of the store against the wall.

However, such fixed attacks have the disadvantage that the Faltschiebeladen can move forward and back unhindered in wind. In addition to unwanted rattling noises, damage to the Faltschiebeladen can occur over time, if this hits unhindered against the angle sheet in wind. In addition, fixed stops allow to bring the Faltschiebeladen only in a specific open position to stop. Between the open position and the closed position of the Faltschiebeladen otherwise - except for the articulation of Faltschiebeladens itself - completely unguided and in particular undetectable.
From the EP 1 905 929 Furthermore, a device for locking a shutter is known. This document refers only to a normal shutter, so not a Faltschiebeladen, and also the locking device is there when the store is open, ie visible at 180 ° tilted loading on the outside and disappears when the shops, eg at night, are closed. Since the locking device must be secured in the soffit of the window, a cranked aesthetically unacceptable bracket for locking is necessary.

Object of the present invention is therefore to provide an over-rotation of a Faltschiebeladens that allows a limited and continuously guided, in particular adjustable pivotability of the Faltschiebeladens between the closed and open position and further preferably allows a releasable locking the Faltschiebeladens 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 over-rotation protection according to the invention is characterized in that to limit the pivoting range of Faltschiebeladens a strut and associated hinge means are provided by means of which the strut one end on the wall and other ends on Faltschiebeladen each rotatable and in addition either on wall or Faltschiebeladen be arranged slidably such that the Faltschiebeladen between the closed position and the open position is limited by a predetermined angle, in particular by 90 °, pivotally.

In accordance with the invention it has been recognized that a continuously guided and at the same time limited pivotability of the Faltschiebeladens can be ensured by a moving along strut between Faltschiebeladen and wall which is rotatable one end and other ends rotatable and displaceable. Since the strut provides a continuous guidance of the Faltschiebeladens over the entire pivoting range, can also be achieved with appropriate design of the hinge means that the pivoting range between the open position and closed position of the Faltschiebeladens 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 Faltschiebeladen means preferably stepped latching means or continuously acting or adjustable friction or clamping forces is designed so that the strut in different displacement positions and consequently the Faltschiebeladen in various intermediate positions between open and closed position form and / or non-positively fixed.

In this case, the strut can be arranged either on the inside of the Faltschiebeladens and correspondingly other ends on the soffit of the building opening. Preferably, however, the strut is disposed on the outside of the Faltschiebeladens and corresponding to other ends on the wall adjacent 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 one end of the strut on wall or Faltschiebeladen. Preferably, the hinge has a stop means to be fastened to the wall or folding sliding shutter, which is connected via a parallel to the pivot axis of the Faltschiebeladens axis of rotation with an end-side connection region of the strut or a terminal arranged on the strut connection element.

As a stop means, for example, an angle plate into consideration, which can be mounted with one of its legs on the wall and on the other leg, the strut is rotatably mounted on an axis which is aligned parallel to the pivot axis of the Faltschiebeladens. 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 an axis of rotation, 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 appropriately aligned slots 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 Faltschiebeladen or wall a parallel to the pivot axis of the Faltschiebeladens aligned cylindrical extension, in particular a pivot provided, which is engageable with a parallel to the pivot axis of the Faltschiebeladens aligned longitudinal groove in Faltschiebeladen. The length of the longitudinal groove typically limits the pivoting range of the Faltschiebeladens.

Thus, the longitudinal groove may be formed, for example, on the lower or upper side of the Faltschiebeladens, in which engages the cylindrical extension at the end of the strut from below or above and is guided therein during the unfolding of Faltschiebeladens. 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 Faltschiebeladen is additionally stored parallel to the pivot axis, ie in particular against gravity, captive on Faltschiebeladen.

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 on Faltschiebeladen or wall a displacement device having a guide element and a sliding element or slidably guided therein or parallel to the pivot plane of the Faltschiebeladens.

In this case, the guide element on the folding sliding 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 Faltschiebeladens.

Preferably, the guide element is designed as a profile rail or slide, in or on which the slider is slidably guided. 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 Faltschiebeladen can be gradually positioned between the open and closed positions in different intermediate positions. In this way For example, the folding sliding shutter can be adjusted to different solar irradiation angles. In addition, the locking displacement mechanism may also have releasable locking means again to set the sliding element relative to the guide element in a specific position.

In order to achieve a continuous adjustment in different intermediate position or to dampen the pivoting range of the Faltschiebeladens in an analogous manner, may be provided by a suitable choice of Reibpaarmaterialen between the sliding element and guide element frictionally engaged, damped displacement according to a further embodiment of the invention.

Also, the sliding element 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 element, similar to a flap brake of 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, even can be dispensed with a sliding device on wall or Faltschiebeladen with guide element and slider. The designed as a pressure cylinder strut is then only rotatably mounted at each end rotatable wall and Faltschiebeladen.

In order to make the Faltschiebeladen space-saving as possible and in particular to allow a flush closing the Faltschiebeladens 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, in particular in the direction the displacement device is angled.

To limit the pivoting range of Faltschiebeladens can 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. In order 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 Faltschiebeladens in wind, it may be provided according to a further preferred embodiment of the invention, that the sliding element, preferably on at least one of the stops, by means of latching connection means or magnetic connection means, in particular in an opening position of the Faltschiebeladens corresponding end position is releasably fixed again. As a result, a releasable locking of the Faltschiebeladens is at least possible in the open position in an advantageous manner.

It is also conceivable that the Faltschiebeladen spring-loaded is held 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. To hold it there against the spring force, a releasable locking or locking mechanism - similar to the locking mechanism of spring-loaded furniture drawers - may be provided on the other stop, which can be preferably brought into engagement with the sliding member or the cylindrical extension.
