Description

DESCRIPTION

Static console for a blind drawer

The invention relates to a static shutter box console for insertion in a blind box, with ^{the characteristics of the preamble of claim} 1 ^.

The windows equipped with a shutter have a blind drawer arranged on the upper crosspiece of the flush-mounted frame, which in modern windows is prefabricated especially from synthetic profiles and can be attached directly to the flush-mounted frame, so that it is not necessary manufacture it in the work through wooden works. The area of the upper recessed frame is considered as a crossbar. This and the fixing up to the body of the construction must be designed in such a way that any static and dynamic load can be absorbed. If this is not the case, due to the greater bending of the recessed frame, there may be a lack of tightness in the area of the work's sealing and a limitation of the function of the window.

To counteract this, for example, documents DE202014101111U1 or EP2636839A2 disclosed metal reinforcement elements that are called static blind box consoles. They present in total a configuration in the form of L, U or C, to be able to wrap the shutter cloth wound on a blind shaft. With its fixing tab to the floor they are joined to the lower side of the blind box and to the flush-mounted frame, and by its locking tab to the ceiling they are joined to the work, especially to a window or ceiling. The fixing must be done either through the top cover part of the blind drawer, or it is even necessary to mill in the blind drawer so that the static blind drawer console can be attached, by its connection tab to the ceiling, directly to the ceiling lintel or to other parts of the work. By milling, however, additional thermal bridges are produced.

In addition, the assembly of the connection tab to the ceiling is difficult in any case, since for this purpose it is possible to work only inside the drawer of open shutter and must work with the blind cloth removed or at least completely unrolled. In blind drawers that can be opened from the inside of the room there is better access compared to the blind drawers that open from below, but for lack of sufficient height it is difficult to apply tools from the inside of the room usual electric In blind drawers that open from below, the height to apply a drill is sufficient, but access is only possible through the relatively narrow opening. Furthermore, for static reasons, the attachment point to the roof connection tab is arranged as close as possible to the center of the blind box, that is to say that it is generally not vertically aligned with the opening in the lower revision cover. Therefore, fixing the connection tab to the ceiling is very difficult and cumbersome, so that contrary to the recognized rules of the art, in practice, the blind drawers are often installed without static consoles of blind drawer , resulting in the disadvantages described above and consequential damages due to wind loads. The protection against theft is also considerably worse without a static blind drawer console, since the upper crosspiece of the flush-mounted frame can be easily deformed, so that it is possible to lift the housings in the recessed frame of the closing elements in the leaf.

In the blind drawer arrangement described in DE202015102179U1 there is no guide element in the static console, but a fixing means is arranged inside a channel in the rear wall of the blind drawer, i.e. in a clearly displaced manner next to the static console. To do this, the blind drawer must have a significantly greater depth than in a conventional blind drawer. The rear wall of the blind box must be additionally reinforced. In the case of using hollow PVC profiles with a thin wall for the construction of the blind drawer, flexural loads resulting from unfavorable force flow can not be absorbed through several points of deflection, nor can it be counteracted by the upsetting that occurs when tighten the concrete anchor that passes through the channel.

Therefore, the invention has the objective of improving a static blind box console for its insertion in a blind box, in such a way that an easier and faster assembly is possible.

According to the invention, this objective is achieved by means of a static blind box console with the ^{features of claim} 1 ^.

The essence of the invention is the provision of a guide element for a fastening element in the rear area of the static blind drawer console. Therefore, the guide element is in vertical orientation and on the side of the blind drawer that is oriented towards the interior side of the building, and also in vertical alignment with a lower revision cover of the blind drawer. The installation of the static blind drawer console according to the invention is remarkably facilitated as regards the connection to the ceiling compared to the state of the art and remains unchanged as regards the connection to the flush-mounted frame or to the background profile of the frame. blind drawer.

The static blind drawer console according to the invention is particularly suitable for mounting without dowels to concrete ceilings, because a threaded bolt having a large central diameter and a relatively small flank diameter is used, in comparison, of a thread that It is especially self-cutting. In this way, it is possible to drill easily through the guide element of the static shutter box console, towards the adjacent part of the work. After fixing the static blind box console at its lower end to the recessed frame and / or to the blind box, there is no need for a previous orientation or marking of the upper fixing point on the ceiling. Then you just have to insert the bolt element into the hole through the guide element.

In addition to the easier assembly, the special advantage of the invention is that a rigid connection is produced to the moments of the static console from the blind box to the ceiling or to other parts of the work, if the drill in the work is done with the sufficient depth and a correspondingly long bolt element is used for fixing. Preferably, the assembly is carried out without pin, so that the threaded pin engages directly in the concrete of the lintel or in other components.

In this way, the connection area to the ceiling is not only immobilized by geometric union at the point of fixation in the three spatial coordinates, but also avoids moments that act on the fixation point. The only degree of mechanical freedom is the rotation perpendicularly with respect to the connection plane, that is, around the axis of the bolt element, but it does not matter in windows and blinds, since, on the one hand, an immobilization of the static blind drawer console to the work site by means of friction connection, since a window is connected to the work by several fixing points located in line and, because, on the other hand, the wind loads always act perpendicularly with respect to the plane of the window.

Except for the fixing hole that is passed through a cover piece up in the blind drawer, no additional cavity is required in the lid part for the mounting of the blind drawer console.

According to the invention, a connection tongue to the cranked ceiling is not essential. However, it is possible to achieve a sufficiently wide contact surface for the contact with the blind box. To stiffen the blind box itself, a bolted connection can be made between the roof connection tab and the top cover of the blind box; for the static function of the static blind drawer console according to the invention this however is not necessary.

A static roller blind console in the sense of the present invention also comprises a so-called central bearing on which axes of divided blinds rest. According to the invention, it also has a fastening tongue to the floor and ceiling and a guide element in the intermediate joining area and can be connected to the work by means of a bolt element.

The guide element provided according to the invention serves to produce the described immobilisation of the bolt-like fastening element to the static blind drawer console with various degrees of freedom. A preferred embodiment of the invention provides for carrying out the guide element as a tubular guide bushing, formed by a tube profile joined by welding or a rolled sheet section. The fastening element used is guided there securely along the entire assembly path.

It is advantageous to complement the static blind drawer console according to the invention with a bolt element adapted exactly, forming a static console assembly kit for the blind drawer. In particular, it is advantageous to use a threaded bolt which can be driven in or screwed in or which, in the manner of a nail-like spike, can later be removed again by unscrewing after being driven. The diameter of reception of the bolt and the outer diameter of the bolt element or the central diameter in a threaded bolt element with thread flanks are preferably adapted to each other. It is also possible to provide the guide bushing with an internal thread and choose a threaded pin with a suitable external thread.

Further advantages of the invention and further advantageous embodiments are described in detail below with reference to exemplary embodiments of the invention, represented in the drawings. In particular, the figures show:

In Figure 1a there is shown a static blind drawer console 10 according to the invention, according to a first embodiment. It consists of a cut sheet metal and comprises at least:

^{- a ground connection area} 11 ^{with a ground fixing tab} 11 ^. 1

^{- a zone of abutment} 12 ^{with a reinforcement core} 12.1 ^and

- a connection area to the ceiling 13 with a fixing tongue to the ceiling 13.1

A guide bushing 14 for a bolt element 20 is formed by a tubular profile and is welded in the throat between the abutment area 12 and the reinforcing core 12.1 located behind the rear edge thereof. In addition to receiving and guiding a bolt element 20, the guide bush 14 also produces a flexural stiffening of the abutment area 12. In its longitudinal extension it can even reach so close to the ground connection area 11 ^{that the reinforcement core} 12.1 ^{can be suppressed in the abutment zone} 12 ^.

As shown respectively in the top plan view in FIG. 1b and the bottom view of the ^{reinforcement} console ^{in FIG.} 1 ^{c, the ground fixing tab} 11.1 ^{ends at such a lateral distance from the reinforcement web} 12.1 as in the alignment of the guide bushing 14 there is a free access for drilling machines and screwdriving tools ^{from the lower side of the static blind drawer console} 10 ^.

In addition, a cavity 11.2 in the ground fixing tab 11.1 is aligned with a cavity 13.2 in the fixing tab to the ceiling 13, so that through these, from a lower revision cover of a blind box, it is possible to Screw the lid part of the blind drawer to a floor ceiling or other component.

The view from below in Figure 1c further shows that there is only a very small distance between the plane of the abutment area 12 and the center of the guide bushing 14. In this way, the load of the static blind box console is reduced by additional bending moments outside the main load direction, which are produced by ^{a displacement of the fixing points with respect to the plane of the ground connection area} 11 ^{, of the} joint ^zone 12 and of the connection area to the ceiling 13.

2 shows a second embodiment of a static console shutter box 10 'according to the ^{invention in a perspective view in comparison with the first embodiment according to figures} 1 ^aa 1c is made differently only in to a guide bushing 14 '. The guide sleeve 14 'is formed here by a section 16' of a sheet metal cut-out by rollers, so that manufacturing is simplified. Welding and rework can be eliminated in corrosion protection coatings of the sheet metal.

Figure 3 shows in a perspective view a static blind drawer console 10 "in a third embodiment that is embodied in the form of a central blind roller bearing. An abutment zone 12 "extends ^{between a ground connection area} 11 ^{" with a ground fixing tab} 11 ^. 1 ^{"and a connection area to the ceiling} 13" with a fixing tab to the ceiling 13.1 ". However, in comparison with other embodiments, the ^{abutment area} 12 ^{"extends preferentially along the front side of the blind box, so that} from the inside of the room it is possible to insert a shutter shaft in the housing of support 17 ". A short guide sleeve 14 "for a screw or a bolt element is arranged on the rear edge to be oriented towards the inner side of the room.

Figure 4 shows the static blind box console 10 according to figures 1a to 1c, which is installed in a blind box 40. The blind box 40 is formed by hollow profiles of synthetic material and comprises a front wall 41, a rear wall 43, a lid part 42 as well as a bottom part 44 that serves in part as a revision lid and that can be opened. Inside the blind box 200 a blind cloth 30 is wound on a blind shaft 31. Parts of the blind 32 hang downwards and move in a guide in a recessed frame 50. The upper side of the recessed frame is fixed a mounting profile in which ^{a bolted connection is made to the fixing tongue to the floor of the blind drawer static console} 10 ^.

In the upper area, the roof fixing tab 13.1 is supported from inside in the blind box 40. At the rear of the step area 12 with the reinforcing web 12.1 there is a distance to the rear wall 43 of the drawer shutter 40, so that a thermoinsulating element can also be arranged there. The bolt element 20 protrudes from the guide bushing 14 very upwards and beyond the upper side of the lid part 42, into a bore 60 in the building.

FIG. 5 shows a fourth embodiment of a static louver drawer console 110 ^{according to the invention, which, with respect to the floor connection area} 11, ^{coincides with a floor fixing tab} 11.1, a bracket area 112. with a reinforcing core 112.1, and with a fixing area to the ceiling 113 with a fixing tab to the roof 113.1 with the first embodiment of the static blind drawer console 10 according to figures 1a to 1c. In comparison with this it is different that a guide element for a bolt element 120 is formed by two guide tabs 114, 115.

The first guide tab 115 is punched out from the reinforcement web 112.1 and bent at a right angle to the inner side of the abutment area 112 of the static blind box console 110. It has a bolt passage cavity 115.1. A second guide tab 114 with a bolt pass cavity 114.1 is disposed directly next to the roof fixing tab 113.1. Also in this embodiment of the ^{blind drawer static} console 110 ^{, the bolt element} 120 ^{is passed during assembly securely by} the guide tabs 114, 115 located at a distance from each other, and also the polyaxial locking of the same. The ^{static blind drawer} console 110 ^{by means of a fixation to the ceiling can be achieved in this variant which can be} manufactured particularly economically.

The fifth embodiment of a static blind drawer console 210 according to the invention, shown in ^FIG. 6 ^{a, is structured in its basic principle as the static blind drawer console} 110 ^{according to the} fourth embodiment according to FIG. and also has a guide element for a bolt element 220, which is formed by two guide tongues 214, 215 located at a distance from each other.

^{As shown in FIG.} 6 ^{b in particular, the difference here is that the fixing area to the ceiling is made in a} separate roof fixing element 113 which can be connected by bolted connection to a bracket ^element 212. The ^{bracket element} 212 ^{it comprises a central stirrup zone ending in a reinforcing core} 212 ^{. 1. Then, downwards, a ground fixing area} 211 ^{is located with a floor fixing tongue} 211 ^{. 1.} In the upper part, the stirrup element 212 has several holes 212.3 on top of one another.

That guide tab 215 having a bolt pitch cavity 215.1 forms the lower end of the ceiling fastening element 213. A second guide tab 214 with a bolt pitch cavity 214.1 is arranged directly next to a fastening tab to the ceiling 213.1 of the roof fixing element 213.

The advantage of the static blind drawer console 210 is that initially only the ceiling fastening element 213 with its roof fastening tongue 213.1 can be mounted on the roof of the building or on other adjacent components above the blind drawer 40 (see Figure 4). The abutment element 212 ^{with the floor connection area} 211 ^{situated next can initially be moved apart, so that, in} view of the lack of space in the blind box, it does not interfere during the assembly of the ceiling fixing element 213 in ceiling. Then, it is subsequently joined to the stirrup element 212 through at least one screw connection.

In addition, an adaptation of the blind drawer static console 210 to different heights within the blind drawer is possible if several holes 212.3 are provided in the bracket element 212 and / or if in the ceiling fastening element 213 there are provided. several drills 213.3, so that these elements can be combined with each other in various ways.
