Abstract

Roller shutters casing comprises a front wall on the outer side of a building, an upper casing wall, a rear wall on the inner side of the building, a base wall, and two side walls positioning the winding shaft. The casing walls are made of rectangular hollow plastic profiles (1, 2, 6) fitted together at their edges. The upper casing wall is divided in the transverse direction into at least two rectangular partial walls which slide into each in the transverse direction and are locked in the desired end position so that the casing depth can be continuously adapted to different wall thicknesses. The depth of the base wall and the two side walls can also be adjusted to the wall thickness. Preferred Features: The upper casing wall is divided into three partial walls. The two outer partial walls attached to the front and rear walls are fixed in the end position on the inner middle partial wall.

Description

Overlay box for roller blind.

The invention relates to an overlay box for roller blind according to the preamble of claim one.

Overlapping blind boxes Roller itself are already known. For example, the documents EP-0843067A2 and EP-263465B1, show This type of superimposed boxes for roller blind. Also document DE-GM8911646U1 describes a roller shutter box consisting of profiles of hollow plastic chamber, the same applies to documents DE-2715909A1 and 2715910. These superimposed boxes for roller blinds they must always be manufactured for openings left in the building and join frontally with the frame of window arranged below, being necessary for each wall thickness a special blind box with the appropriate dimensions for that. The joints of the various pieces of an overlay box for roller shutter of this type with each other and the box for Full blind with the window frame are normally performed through clip joints.

It is obvious that this requires considerable work in terms of tools, extruded profiles, storage and transport capabilities.

In addition the document has been known DE-4237956A1. Here it is a device of box with a housing box open down to accommodate a roller shutter to be provided with such formwork box lintel, which forms a lost formwork, making a superfluous a additional lintel formwork in construction. They also show adapters for a roller blind box, which allow to combine different types of different window dimensions with an overlay box for roller shutter, such as follows from document DE-4416866C1 and, in addition, according to document DE-19751756A1 are shown Thin-walled shutter boxes for household items prefabricated with variable pocket space, which due to its special features are set so thin that during manufacturing they guarantee the incorporation flush in the wall elements. Such boxes cannot be used in normal wall thicknesses.

Given the background of this state of technique, the invention aims to create in a simple way a superimposed box for roller blind, adaptable to all wall thicknesses.

This objective is achieved with the characteristics of claim 1. The subordinate claims indicate advantageous embodiments.

The advantage obtained with the invention consists in especially in the easy adaptation of the superimposed box for roller blind to the corresponding wall thickness, in a reduced transport space and, particularly, in a Simplified manufacturing, due to the need for a single tool for the coupling or joining profile of the upper part, and in a limited storage

The invention is explained in more detail in the figures with the help of an embodiment.

Shows:

Fig. 1 a section through a box overlay for roller shutter,

Fig. 2 a coupling profile of the box overlay for roller blind according to figure 1,

Fig. 3 a connection profile of the superimposed box for roller blind according to figure 1,

Fig. 4 an upper part of the superimposed box for roller blind according to figure 1, and

Fig. 5 a plaster support plate of the box overlay for roller blind according to figure 1.

The superimposed box for roller blind represented in figure 1 is substantially composed of a box-shaped housing with upper and lower sides composed of profiles 1, 2, 6 plastic holes, of plates 3 lateral plastering support and the two upper 4 pieces, the profiles 1 hollow plastic shaped in the form of coupling profiles or joining profile and at the bottom in the form of 6 cover review. In addition, thermal insulation 5 is represented, a roller shutter guide 7, an input funnel 8 of armored roller blind, as well as a part of a shield 9 of roller shutter with exit 10, a joint cover 11 of plastering and a window frame profile 12, on which it is fitted overlay box for roller shutter.

The upper side of the box overlaid for roller blind consists of two coupling profiles 1 arranged to the right and left and a planned connection profile 2 between those two coupling profiles. Coupling profile 1 it is connected on one side with the plasterboard 3 by means of of a coupling angle of the coupling profile 1 that engages in the slot 3a housing it.

In figures 2 and 3 you can see that on the side opposite the coupling profile 1 a connecting hook 1b is provided which engages in interlocks 2a to 2e on the right and 2f until 2k on the left, arranged at different distances from the central point of the joint profile 2. With such provision of interlocks can be covered almost every depth that is They can hit the masonry. The connecting element 2 is provided in addition to 2l channels, m thread for joining with part 4 upper, while the coupling element 1 presents 1b, c thread channels for this joint.

Figure 4 shows the upper part 4 with its 4a compensation surface for adaptation to wall thickness corresponding and with the recesses 4b for the accommodation of the belt pulley or other accessories not shown.

Figure 5 shows the plate 3 support plastered with its housing slot 3a for coupling with the coupling profile 1. The plaster support plate presents in its outer part 3b ribs for the best adhesion of the plastered to be applied, as well as a 3c projection for the housing cover 11 plaster.
