Two end walls (7) are provided to close the roller-shutter casing in a lateral manner. The roller-shutter casing is assigned to a set of two or multiple lamella guiding parts (13) which have guide grooves (12) of different widths.

Description

The invention relates to a roller shutter box, in particular as a landing roller shutter box trained, preferably composed of plastic extrusion and / or plastic injection molded roller shutter box, with a front wall, a rear wall and a ceiling wall, and two shutter boxes laterally closing end walls, further with a slat guide part having a guide groove and the upper side is associated with an inlet part, wherein with respect to the slat guide part different width guide grooves are providable.

Roller shutter boxes of the type in question are known. These are usually suitable for receiving roller shutter shells with different Stabnenndicken, further in particular of roller shutter rods with 7mm or 8mm and 14mm thickness. For this purpose, slat guide parts are used with correspondingly adapted clear widths having guide grooves, wherein the outwardly facing edge of the guide groove is the same regardless of the Führungsnutbreite or regardless of the slat guide part used. Accordingly, the pointing inward in the direction of the window frame edge of the guide groove to change the clear width is variable. The box-side inlet part or an inlet flank formed by the inlet part for guiding the lamella bars into the guide groove is always assigned to the inner flank facing the window and / or door frame. Accordingly, a change in the clearance of the guide groove causes a positional adjustment of the inlet part.

In view of the known prior art, a technical problem of the invention is seen in a roller shutter box of the type in question, in particular with regard to a cheap production to improve.

This problem is solved first and foremost by the subject matter of claim 1, wherein it is pointed out that the roller shutter box is assigned a set of two or more slat guide parts which have guide grooves of different widths, wherein in the installed state the horizontal distance of the window-side flank of the guide groove is the same to the inner surface of the shutter box front wall in all the slat guide parts, or that - only - a slat guide member is provided, the leading edge is variable by removing a flank member with respect to the distance to the inner surface of the shutter box front wall, wherein the window-side flank is the same. According to the proposed solution, the window-side flank of the guide is always the same regardless of the selected clear width of the same distance to the window and / or door frame assignable edge of the slat guide part. The change of the clear width is achieved by appropriate positioning of the outwardly facing guide. This offers in particular the manufacturing advantage that the position of the inlet part, in particular its inlet shoulder remains the same for all widths of the guide. An adjustment of the positioning of the inlet part is eliminated. Adapted to the bar thickness of the roller shutter shell to be used in the roller shutter box, a corresponding slat guide part with a width-adapted guide groove is provided in one embodiment. Alternatively, in particular with a specification of only two differently wide guide grooves or with a specification of only two different thickness bar thicknesses, only a lamellar guide member is provided, facing away from the window and / or door frame, according to outwardly facing edge of the guide according to removal or Insertion of a flank part in the spacing to the fixed, window-side flank is changeable.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

The flank part is, for example, by production-designed notches or predetermined breaking points with the, the guide groove having slat guide part connected, wherein existing flank part, the minimum width of the guide adjusts. By breaking out of the flank part, for example, the guide groove can be expanded to its maximum width. Further alternatively, the flank member is inserted to reduce the width in the guide groove. The flank part can also be connected to the outer flank of the lamella-side guide groove via a tear-off line (material-weakened zone). In a further preferred embodiment, it is provided that a removal of the flank part is made possible by repealing a plug connection. In this context, more preferably, the slat guide part as well as the steckverbindbare flank part is made as a plastic extrusion, more preferably initially for captive assignment, the flank part is plugged into the guide groove in such a way that thereby the minimum Führungsnutbreite is reached. The outwardly facing, according to the window and / or door frame repellent edge of the guide part side guide groove is designed to plug-holding the flank part, preferably corresponding in cross-section Hintergreifabschnitte or the like, which are grasped by corresponding portions of the flank part in the plug assignment position. The cooperating region extends in a further preferred embodiment over the entire vertical extent of the guide groove in the installed state of the slat guide part. Alternatively, these are vertical Length considered only isolated, more preferably evenly spaced areas formed for Steckzusammenwirkung.

The connector is selected in a preferred embodiment so that it is reversible, so that in a further embodiment, a made plug determination of the flank member to minimize the Führungsnutbreite by removing the flank part is canceled again, after which sets the maximum Führungsnutbreite.

Advantageously, the inlet part is designed in the same fixing position on the end wall for cooperation with all two or more guide grooves of different widths. Accordingly, there is no need to adapt the inlet part in terms of its positioning and / or orientation regardless of which clear width has the guide groove. This minimizes both the manufacturing effort and the effort in the course of the shutter box packaging.

The inlet part is preferably plug-connected to the slat guide part, wherein more preferably an inlet part of the same design is always plugged into the inserted slat guide part even when assigning a set of two or more slat guide parts with different width guide grooves.
