Description

The invention relates to a building opening shading device, for example a vertical awning or a roller shutter, which has a winding shaft driven by tubular motor, according to the preamble of claim 9, and a component therefor.

In building opening shading devices of the generic type is due to architectural developments such as the increasing facade insulation less and less space for installation of the winding shaft available. The demands on the optimal space utilization thereby increase, and thereby also the complexity in the assembly at the construction site, and above all during the disassembly for maintenance purposes.

This applies in particular to the wiring of the tube motor used to drive the winding shaft when removing the winding shaft, as described, for example, by the US patent application US 2004/0129849 A1 can be seen. The coming of a fixedly arranged side panel cable is guided through an entrance slot in a peripheral side wall of a component on the front side of the engine head to a plug-in connector which is fixed in the engine head. When removing the winding shaft, the plug-in connector must be loosened, which is difficult in confined installation spaces.

In order to facilitate the installation and removal of such winding shafts, it is known to provide the winding shaft at its end facing away from the tubular motor with a spring-loaded extension piston, such as the European patent specification EP 1 746 244 B1 can be seen. When installing the winding shaft this is initially recognized with its resiliently received end to the associated receptacle, for example on a visor of a winding shaft box obliquely and then brought under pressure and concomitant shortening of their length in the horizontal position, where they then with their tubular motor end, ie is placed with the engine head of the tubular motor to the associated receptacle, normally on the opposite visor, under the action of spring force of the resilient end. The disassembly runs accordingly in reverse order.

In this case, the power supply of the engine head in known, provided with such a resilient winding shaft Gebäudeöffnungsverschattungsvorrichtungen via a building side connected with cables plug connection with a building-side connector and a motor-side connector, with the two plugs solve by squeezing the winding shaft during removal and by the extension of the Let the winding shaft connect during installation. The spring travel must therefore be large enough that for installation and removal of the plug sufficient space in the axial direction between the compressed winding shaft and the visor cap is present. In this case, the insertion and removal of the power supply in tight installation spaces designed by nature, while also compressing the winding shaft and the plug connection must be solved, so that normally two fitters are necessary for this operation.

For ease of assembly, therefore, plug connections of tubular motor head and the power supply line to be connected thereto have been proposed in which the axial mounting space required for insertion and removal is as small as possible. Thus shows the European patent application EP 2 354 430 A2 a winding shaft in which a multi-core power supply line with the pipe engine head side ports via a connection with a male and a female Connecting piece is connected.

In addition to such power supply lines with one or more individual lines, it would also be conceivable to connect the tubular motor with bus systems or other control lines.

On this basis, it is an object of the present invention to simplify assembly in generic building opening shading devices, especially in confined installation spaces.

This object is achieved with regard to the building opening shading device having the features of claim 9, with regard to a component used for this purpose having the features of claim 1.

According to the invention, a tubular motor cable drum is provided for the supply cable or for receiving a cable section of one or more connected to the motor head cable, which is suitable for arrangement in the region of the engine head and one or more turns or even a partial turn of the with the local and rotatably supported on the building side supported motor head connected supply cable. Accordingly, in the building opening shading device according to the invention, which may in particular be a vertical awning or else a roller shutter, in the region of that end face of the tubular motor provided as a winding shaft motor to which the tubular motor mounted a stationary and rotationally fixed to an associated building-side holding part motor head comprising a tubular motor cable drum wound with a portion of the cable connected to the motor head according to the invention.

The wound on the tubular motor cable drum section of the cable can serve as a facilitating the assembly cable reserve. If the winding shaft is taken out with the integrated tubular motor from its building-side storage on the engine head, for example by the above described pressure exerted on the other, advantageously spring-trained end of the winding shaft, so wound up on the tubular motor cable drum cable section unwind until the winding shaft enters an inclined position in which it with its other, the engine head end facing still in the associated storage , For example, depends on the box side part, with its connected to the cable and the engine head end, however, hangs out of the box inside or out of a drive bay, so that the fitter the front side of the engine head and thus advantageously provided there connector connection is easily accessible. At the same time, the cable reserve wound onto the tubular motor cable reel ensures that during the operation of the building opening shading device, no loose-hanging cable rubs against the moving parts or gets caught.

The tubular motor cable drum could theoretically be arranged eccentrically to the tubular motor or winding shaft axis, or even with an axis not aligned with the tubular motor or winding shaft axis. Due to the cramped installation conditions in modern Gebäudeöffungsschwattungsvorrichtungen, for which the cable drum according to the invention is mainly provided, it is advantageous if the tubular motor cable drum is provided for arrangement with the winding shaft axis aligned axis, so that the tubular motor cable drum be either externally peripheral side mounted on the tubular motor can or can be arranged in the axial extension of the tubular motor head between the engine head and the side panel or the side panel or any other, provided for supporting the winding shaft, building-fixed part.

All possibilities are open for the integration of the tubular motor cable drum into the winding shaft bearing arrangement. Thus, the tubular motor cable drum could be formed integrally with the motor head of the tubular motor. In this case, the subject of the invention would extend to a tube motor cable reel unit incorporating the tube motor.

It would also be conceivable to integrate the tubular motor cable drum into a one-piece unit with a blend cap, or a side part, on which the winding shaft is supported by the tubular motor head. In this case, the subject of the invention would extend to such a visor cable reel unit.

Advantageous in the sense of retrofitting existing units and the simple integration into the manufacturing process, however, the tubular motor cable drum is designed as a separate component. The tubular motor cable drum does not have to be firmly connected to the engine head or the side panel or the hood, as long as it is ensured that the engine head can be supported against rotation on the side panel and the cable drum is not exposed to entrainment by the winding shaft in the direction of rotation is. However, preferably designed as a separate component tubular motor cable drum on means for stationary and rotationally fixed mounting on the engine head. Alternatively or additionally, means for stationary and rotationally fixed support on the associated side part of the building side mounted winding shaft receptacle may be provided.

If the tubular motor cable drum is combined with the motor head to form a one-piece structural unit or fixed in place and rotationally fixed, it is advantageous if the motor head is supported via the tubular motor cable drum on the associated building-side holding part, so if the tubular motor cable drum means has for stationary and rotationally fixed support of the engine head. Incidentally, this also applies if the tubular motor cable drum is provided as a separate component.

If the tubular motor cable drum is integrated into the side cap or the hood or attached to the visor cap, it is on the other hand advantageous if it has the means by which the engine head can be supported on the building side.

It is easier when disassembling the winding shaft when the cable drum together with the winding shaft of the engine head associated, the building side Recording is taken as if it remains there and alone the winding shaft is removed with the tubular motor. Because then the supply cable can be unwound from the cable drum by slightly rotating the winding shaft during removal. Advantageous in this sense, therefore, developments of the invention, in which the cable drum is integrally or fixedly connected to the winding shaft. Existing tubular motors, however, are difficult to modify, so that the development is preferred as a separate cable drum component.

Is the tubular motor cable drum in the axial direction together with the winding shaft peelable and connected to the motor head that dissolves when moving the tubular motor in the axial direction, the connection of the tubular motor cable drum with the side panel and not the connection of the tubular motor cable drum with the motor head, so this is exactly what is achieved. In addition, then the tubular motor cable drum when removing the winding shaft act as a cable strain relief for the plug connection to the engine head of the tubular motor. Optionally, the tubular motor cable reel may also include an additional cable brake for the cable, such as a component attached thereto through which the cable passes with narrow radii. If the winding shaft is then removed with its engine head end from the associated building-side recording, even then no train on the plug on the engine head, if the installer does not hold the winding shaft. If a corresponding strain relief or a suitably robust connection point is provided at an end opposite the motor head side plug, the installer can even deliberately use the cable to hold the winding shaft during deflation. Instead of the cable drum-side strain relief but could also be provided a correspondingly robust plug connection on the engine head to replace the cable or in this way for ease of assembly.

The tubular motor cable drum can be screwed for example to the engine head and be releasably connected to the associated side part via suitable connectors. The connectors of the side panel with the tubular motor cable drum can, for example, a number annularly arranged around the winding shaft axis around pin on the side part or a motor head and the cable drum facing surface of the side part, which on the tubular motor cable drum as a means for mounting on the side part a suitable number in a row are assigned to the winding shaft axis arranged around Einsteckausnehmungen, which are thus provided on the side part facing the front side of the tubular motor cable drum. Of course, it would also be conceivable to provide Einsteckausnehmungen on the side part, which are assigned to the side part facing the front side of the tubular motor cable drum (or the tubular motor) corresponding spigot.

Advantageously, the tubular motor cable drum has an annular portion with an at least substantially cylindrical inner peripheral surface with which the tubular motor cable drum can be pushed onto the outer circumference of the motor head, thereby easily verifying on the engine head, with only against rotation or movement in the lateral part facing axial direction must be secured, for example via positive engagement elements on the inner circumference of the tubular motor cable drum, which can intervene in appropriate exceptions on the tubular motor head, if there are such exceptions. If the tubular motor cable drum also has a wall extending in axial normal direction or at least wall sections in which boreholes are provided for screw connections, then the twisting and extracting safety device can be screwed to the end face of the motor head.

In order to secure the recorded on the tubular motor cable drum cable section against slipping and thus against the risk of coming into contact with the rotating parts of the winding shaft and to catch it, the tubular motor cable drum advantageously has a circumferential winding portion laterally enclosing annular disc sections Guide the recorded cable section. However, it would also be conceivable, the annular disc section to let away on the side facing the side of the cable drum and to use as a guide on this page, the vertical wall of the side part.

In order to be able to lead the supply cable or control cable or both from the engine head via the tubular motor cable drum to corresponding building-side connections, while a cable inlet to the tubular motor cable drum is provided through which coming from the engine head cable between the annular disc sections on the tubular motor cable drum or their winding section can be performed. Depending on how the tubular motor cable drum is arranged with respect to the motor head, the cable inlet may be provided at various locations, for example by the cylindrical or conical wall forming the inner circumferential surface on the one side and the winding section on the other.

If a direct cable routing on the outside of the tubular motor cable drum in the region of the annular portion facing the tubular motor is not possible from the motor head side connector, through the opening formed by the cylindrical inner peripheral surface of the tubular motor cable trommel and then through one in the side part facing Ring disc section provided cable passage gap therethrough. Preferably in the sense of a simple cable laying, however, it is when in the tubular motor facing annular disc portion, a gap is formed through which the cable coming from the tubular motor head plugged and then wound with the appropriate cable section on the winding section of the tubular motor cable drum. If the cable inlet is designed accordingly narrow, he can simultaneously fill the function described above as a strain relief for the engine head side plug connection when winding shaft.

Further advantageously can be provided on the motor head side part associated outer peripheral side mounting elements, with which the circumferential winding portion of the tubular motor cable drum outside circumference is enclosed with a the cable section to be wound corresponding distance, so as to prevent unwanted unwinding of the cable with even greater certainty.

Preferably, the revision engagement with the winding shaft in the vertical awning or building opening shading device according to the invention takes place from below, so that the winding shaft on the cable can be lowered downwards out of its installation space. For this purpose, the vertical awning preferably has a lower-side revision cover arrangement on its winding shaft box.

Further features and advantages of the invention will be explained in more detail with reference to the embodiments illustrated in the accompanying drawings.

The winding shaft 3 is formed as a formed from a sheet metal, cylindrical member to which the awning fabric 4 is attached with its one end. The winding shaft 3 has a radially inwardly facing cam groove 31 and a likewise radially inwardly projecting sheet metal overlapping portion 32 and sits on an intermediate sleeve 20 on the outer circumference of a generally designated 8 tubular motor. At the rotating part of the tube motor 8 drivers are provided, see in Fig. 1 on the outer circumference of the outwardly projecting Mitnehmerstein 85, via which the intermediate bearing sleeve 20 is taken from the rotating part of the tube motor 8. The intermediately mounted bush 20 in turn takes the winding shaft 3 with it. It should be noted that in another building opening shading device, such as a roller shutter, the winding shaft may have a different outer surface, such as a hexagonal outer peripheral surface, but the inner structure with a tubular motor driving the winding shaft via corresponding driver tubular motor is substantially the same.

The generally designated 8 tubular motor is the FIG. 2 to be taken in detail. It has a rotating part 89 and a stationary and rotationally fixed to the associated trim cap 9 recorded motor head 82. In addition to the driver 85, the rotating part 89 at its end facing away from the engine head further has an end portion 86 with recesses for positive engagement with corresponding drivers on the sleeve 20.

The tubular motor cable drum 40 in this case has an annular plug-on section, with which it can be plugged onto the tubular motor head 82. At the side part 9 facing the end of the annular Aufsteckabschnitts are two inwards projecting tabs 143 are provided, which are penetrated by through holes. Here, the tubular motor cable drum can be screwed to the provided on the motor head 82 threaded holes 87. The cable 84 is thereby brought in the manufacture of the plug 83 through a cable inlet slot 45 through the tubular motor cable drum and placed there with about 1 ½ windings. The cable inlet slot 45 is located in a side facing the engine head side wall 42 and a motor head facing side ring portion 42 of the tubular motor cable drum 40, which has a wavy contour on its outer circumference. The wavy contour has the advantage that, see FIG. 6 in that the cable 84 is securely held between a projection 19 projecting from the side cover 9 radially outward of the tubular motor cable drum and a portion of the side wall 42 directed far outwardly, but adjacent thereto at a less far outwardly directed portion of the side wall 43 from the circumference of the tubular motor Cable drum can be steered.
