Description

The invention relates to a building opening shading device according to the preamble of claim 1.

In the field of roller shutters, etc., it is known to equip the winding shaft, on which the curtain is wound up and unwound, at one end face with a telescoping support piece or extension piston.

Thus shows the European patent application EP 1 568 844 A1 a telescopic winding shaft for a roller shutter. For fixing the winding shaft during assembly of the roller shutter belt there is provided a locking of the two ends of the winding shaft in each case by a sliding bolt in the lateral bearing. The sliding bolt can be pushed up into engagement with a sleeve which is received in a form-fitting manner on the winding shaft. For this purpose, the sliding bolt on the one hand upwardly projecting pins, which are thereby pushed into recesses in the radial direction projecting pin on the sleeve to prevent rotation of the winding shaft. On the other hand, the sliding bolt has an upwardly projecting shoulder, which is thereby pushed on the inside in winding shaft axial direction in the rear grip with the radially projecting pin on the sleeve to prevent the winding shaft on a Einteleskopieren by the sleeve is held axially ,

In building opening shading device with telescoping winding shaft but is not the main problem, the winding shaft for installation in the workshop completely set - as in the EP 1 568 844 A1 explained - but to ensure during operation, so with rotatable winding shaft, that the support piece can not be undesirable pressed into him receiving winding shaft, ie to ensure that the winding shaft is secured in operation against falling out of their storage between the two sides.

Generic Gebäudeöffnungsverschattungsvorrichtung have for this purpose a resiliently supported in the form of a hollow shaft winding shaft and usually biased by spring force in the austeleskopierte position carrier nozzle, and a locking device for fixing the axially movable carrier nozzle on the other hand axially fixed hollow shaft.

The support piece, which forms a bearing pin for suspending the winding shaft on the side part of the shutter box, is thus supported axially movable by a spring in the winding shaft or the hollow shaft, so that the winding shaft during assembly with the resilient end (the resilient extension piston) at an angle the appropriate storage on the side panel and can press with the winding shaft on the support tube, then to pivot the other, rigid front end with depressed carrier piece up and at the designated camp on the opposite box side part under spring force extending expansion of the winding shaft to use their original extension.

There are already various possibilities have been proposed, with which the support piece can be secured to the winding shaft or the hollow shaft against an undesirable during operation axial impressions.

An example shows the European patent EP 1 746 244 B1 , In order to fix the carrier nozzle in a specific axial position there is provided a removable rider, which passes through a slot in the winding shaft and engages in corresponding grooves on the extension piston. Similar solutions are the German Utility Model DE 20 2007 004 845 U1 and the European patent application EP 0 730 080 A1 refer to. However, these backup components are relatively difficult to install in confined spaces in the installation space of the winding shaft.

A winding shaft with a resilient end also shows the European patent application EP 1 936 106 A2 , The support piece is received axially displaceable in a pressed-in the winding shaft end bushing, and displaceable against spring force. For fixing the pin or carrier nozzle in a desired axial fixed position, a ring is provided, which can be screwed onto a thread on the carrier piece. This gland is relatively accessible. The screwing on and off with built-in winding shaft is still cumbersome. A similar solution with a screwed onto the extension piston retaining ring is the French patent application FR 2 934 307 A1 refer to.

On this basis, it is an object of the present invention to provide a genus with a trained as a hollow shaft winding shaft and a telescoping recorded therein carrier nozzle building opening shading device with an easy-to-use and inexpensive to manufacture safety device against unwanted compression of the built-in winding shaft.

This object is solved by the features of claim 1.

According to the invention, the securing device on the one hand has an axially outward direction pointing, stop surface on the provided with the support piece end face of the hollow shaft. On the other hand, on the associated side part of the hollow shaft toward projecting counter stop pin with a stop surface facing the counter-stop surface. Since the abutment surface rotates with the hollow shaft and the counterstop surface is fixed, the abutment surface is in particular annular. The Gegenanschlagszapfen is from a securing or locking position in which it is located at the radial height of the annular stop and compression of the rotating shaft in the operating position winding shaft (ie, a depression of the carrier nozzle in the winding shaft inside) prevented or at least limited, removable on associated side member added or movable out of its securing or locking position.

Securing against unwanted impressions of the carrier nozzle is thus indirectly by limiting an axial direction to the side portion of possible movement of the rigid hollow shaft, in which the carrier nozzle is in turn received axially movable, and not directly by limiting the possibility of movement of the carrier nozzle relative to the side part or the diaphragm cap or against the hollow shaft receiving it. Nevertheless, an axial relative movement of the carrier nozzle relative to the hollow shaft is prevented to the extent that it is ensured that the support sleeve not so far against the bearing a bearing receiving bearing carrier or the side part can be pressed that the winding shaft as a whole far enough telescoped to get out of their To solve the seat.

The fact that the part of the securing device to be actuated by the fitter is now provided on the side bearing part of the building opening shading device instead of on the support piece to fix this against the hollow shaft, and in that this movable part of the securing device also only has to be brought into its securing position or removed from this , The safety device can be designed overall easy and inexpensive. It is sufficient to provide an annular stop surface on the hollow shaft, for example on an annular flange and z. B. a height-adjustable latch with the counter stop pin that can be removed for assembly purposes or preferably in terms of better captive security on the side panel directly or on another, there fastened component, such as a bearing bearing bearing plate can be added.

Furthermore, a good accessibility of the fitter to be actuated by the installer of the securing device can be achieved because in the region of the side part for a downwards sufficient space in the winding shaft installation space to the provided with the counter-stop member, so preferably a height-adjustable on the side bearing part recorded safety slide, extend down to the bottom of the installation space of the winding shaft, and because on the other hand, the side bearing part and thus the safety slide with the counter-stop pin does not rotate with the winding shaft.

Of course, the length of the hollow shaft is of course chosen in such a way with respect to the axial spacing of the side parts that a clearance exists between the hollow shaft-side stop surface and the counter stop surface. The counter-stop surface of the counter-stop pin is therefore also in the securing position advantageously spaced slightly from the abutment surface on the winding shaft in order to prevent rubbing of the winding shaft on the counter-stop pin. However, due to wind loads or the like, this will not always be preventable. These transverse forces acting on the winding shaft during operation are precisely the reason why a safety device is provided against unwanted impressions of the carrier nozzle into the hollow shaft. In addition to the distance between stop surface and counter stop surface, the counter stop surface may therefore be provided with a material with a low coefficient of friction, for example plastic.

In other words, the counter stop surface may be provided on a component which consists of such a material or is coated with such a material. Advantageously, the counter-locking pin having safety slide therefore made of plastic. On the other hand, the abutment surface may be formed on a sleeve which is mounted on the end face on the hollow shaft and which then has an end-side, axial, outwardly projecting annular flange on which the annular abutment surface is formed. The sleeve can advantageously be at the same time the necessary for receiving the support nozzle, recorded in the hollow shaft inner sleeve. The sleeve is due to the male loads as well as the support stub preferably made of a metallic material such as zinc die-casting, but could also be coated on the stop surface with plastic.

It is also advantageous if the safety slide on which the counter-stop pin is formed, for example, as a counter-protruding pin projecting at right angles from a base portion, is captively received on the side part directly or on a component fastened to the side part, displaceable between the securing position and one Release position in which the counter-stop pin radially outside the annular abutment surface is so, for example, above the provided on the hollow shaft directly or on the inner sleeve ring flange.

For displaceable mounting of the safety slide can advantageously be a plate, for example, a bearing for a bearing journal bearing support bearing plate mounted on the side part, on which the winding shaft facing side of the safety slide rests, and which is engaged behind by the safety slide. Between the plate and the side part can then be a slot into which the safety slide can engage with its plate engaging behind the section. The safety slide is then advantageously taken up with exclusive freedom of movement in the direction of displacement between its two positions, the release position of the securing position on the side part or on the plate attached to the side panel.

It is also advantageous if a releasable latching connection of the safety slide with the plate connected to the side plate, so for example the bearing plate is provided, wherein the locking connection for releasably latching the safety slide serves in its securing position and thus prevents the safety slide unintentionally from the the winding shaft against a compression locking securing position triggers. Further advantageously, the latching connection can also be designed so that it secures the safety slide in its release position on the bearing plate.

The latching connection may advantageously have a projecting from the winding shaft back of the plate, for example, the bearing plate locking pin which is encompassed by two legs of a plate, for example, the bearing plate on the upper side engaging behind locking fork of the safety slide, which two legs thus simultaneously the plate, for example Can form bearing plate engaging behind section of the safety slide.

The bearing plate engaging behind sections or the bearing plate engaging behind portion of the safety slide can be angled from a running on the winding shaft side facing the bearing plate base plate of the safety slide.

This base plate can be configured as an annular Verliersicherungsabschnitt, which surrounds the bearing provided on the side part bearing and the bearing pin therein radially on the radial side and thus ensures that the safety slide does not fall even if the rear handle should solve on the bearing plate.

Advantageously, the counter stop pin protrudes above the bearing from the base plate or the Verliersicherungsabschnitt of the safety slide in the axial direction, because it is particularly easy for a mechanic to operate a height-adjustable safety slide and then because of the Verliersicherungsabschnitt downwardly projecting actuating portion may be provided on the safety slide, which must be moved by the fitter only up or down, which further facilitates access to the safety slide. The opening through which the bearing pin and / or the bearing is passed on the annular Verliersicherungsabschnitt of the safety slide can then advantageously be aligned with a vertical axis slot.

The downwardly projecting operating portion is advantageous from a fitter gripped, so that no height adjustment of the safety slide tool is needed and therefore has on the underside advantageous to the winding shaft angled towards operating tab.

Further advantageously, the downwardly projecting actuating portion having an underside securing tab, which is angled in the opposite direction, ie away from the winding shaft and at least in the securing position on an associated, downwardly facing retaining shoulder on the bearing plate, resulting in interaction with the upper side provided on the safety slide locking fork results in an even better locking of the safety slide in its securing position. The actuating portion may then be formed as a bending leg, which results in a safety slide made of plastic almost by itself, which is so far wegbiegbar with its underside of the bearing plate that the locking tab out of engagement with the retaining shoulder.

Further advantageous developments are explained in more detail with reference to the Ausführungsfom of the invention shown in the accompanying figures. Show it:

18 and 19 that in the 16 and 17 shown side bearing module seen from the side facing away from the winding shaft in a secure against compression of the winding shaft securing position ( 18 ) and in a compression of the winding shaft permitting mounting position ( 19 ).

First, reference is made to the 1 in which a total with 10 denoted, hollow winding shaft is shown, which at its two front ends in each case on a visor cap or on a side part 1 respectively. 11 of the not otherwise shown winding shaft box is stored. The side parts 1 . 11 can be identical, the winding shaft 10 on the side of the side panel 11 However, is supported axially fixed on their tubular motor, on the side of the side part 1 In contrast, via an axle cap module with a telescopic, spring-supported support in the winding shaft 6 , and attached to the visor side bearing module as will be explained in more detail below. It is in the 1 shown a winding shaft for a vertical awning with a round cross-section, but the invention can also be realized on a cross-sectionally polygonal winding shaft, as used for roller shutters, as well.

The resilient axle cap module points, like 2 shows an inner bush 5 . 9 on, consisting of two screwed together clamping bushes, an outer clamping bush 5 and an inner clamping bush 9 is formed. In the inner bush 5 . 9 is a over a Ausschubfeder 7 outwardly biased carrier neck 6 recorded with exclusive degree of freedom of movement in winding shaft axis, over which the winding shaft 10 in one on the side panel 1 attached side bearing 2 . 3 is supported. The side bearing 2 . 3 has an inner ring designed as a spherical cap 2 on the end of the support tube 6 is mounted, and a bearing plate 3 on the side panel 1 is attached and on the one the bearing inner ring 2 receiving bearing outer ring 31 ( 4 ) is formed.

The carrier neck 6 forms together with the two clamping bushes 5 . 9 and the Ausschubfeder 7 a tensioning element 5 . 6 . 7 . 9 , which by a with 8th designated clamping bush is guided, or the clamping bush 8th passes through and over which the clamping bush 8th in the winding shaft 10 is clamped. The through the two clamping bushes 5 . 9 formed inner bush 5 . 9 forms together with the clamping bush 8th through which it passes, a bushing arrangement 5 . 8th . 9 ,

The outer clamping bush 5 points out how in 7 is shown, an outer peripheral portion with an external thread 53 on, the inner clamping bush 9 facing, which in turn at its outer clamping bush 5 facing side an inner peripheral portion with a corresponding internal thread 93 having. The two clamping bushes 5 . 9 are thus screwed together and can move towards each other by tightening the screw in winding shaft axis direction and away from each other by loosening the screw.

In this case, the outer clamping bush 5 a radially outwardly projecting stop flange 52 on and the inner clamping bush 9 an outer circumferential section or wedge section which tapers conically in the direction of the winding shaft axis from the inside to the outside 92 (please refer 8a ). The clamping bush 8th on the other hand has one at a slot 86 slotted ring section 81 up, see 11 of which a plurality of concentric with the winding shaft arranged spreading or counter wedge segments 83 protrude inwards in the winding shaft axis direction.

The inner peripheral surfaces of the counter wedge segments 83 run on one of the cone shape of the wedge section 92 the inner clamping bush 9 corresponding cone contour and may be due to due to segment interspaces 85 split compartment structure, if the screw connection of the two clamping bushes 5 . 9 is tightened and the two clamping bushes then move towards each other and thereby on the radially projecting stop flange ring 52 on the outer clamping bush 5 on the one hand and the cone-shaped wedge section 92 at the inner clamping bush 9 on the other hand, a radially outwardly directed pressure on the counter wedge segments 83 the clamping bush 8th exercise.

The tensioning element 5 . 6 . 7 . 9 and the clamping bush 8th thus form by tightening or loosening the screw of the two clamping bushes 5 . 9 operable wedge gear, over which the clamping bush 8th against the inner circumference of the hollow winding shaft 10 can press, resulting in the entire axle cap module in the hollow shaft 10 anchoring.

It is ensured by various measures that when turning the outer clamping bush 5 the inner clamping bush 9 is held against rotation, so that the screw connection of the two clamping bushes 5 . 9 ever let operate. On the one hand, the wedge angle is on the conical wedge section 92 the inner clamping bush 9 and at the through the counter wedge segments 83 formed counter wedge section 82 the clamping bush 8th chosen very small, in the example shown about 10 °, with the wedge or counter wedge sections 82 . 83 extend over a relatively large axial length and almost around the entire circumference. As a result, only a virtually self-locking frictional engagement between the inner clamping bush 9 and the clamping bush 8th reached. Beyond that, see 8b , two Finns 95 from the inner clamping bush 9 in the wedge section 92 radially outward, each one segment gap 85 - please refer 14 - between two counter wedge segments 83 pass through and directly on the inner circumference of the hollow shaft 10 support. Between the two radial fins 95 is also a Mitnehmer- or retaining groove 94 Außenumfangsseitg in the inner clamping bush 9 molded, with which the inner clamping bush 9 at an in 10 to be recognized, from the inner circumference of the hollow shaft 10 inwardly indented groove wall 12 a Kedernut can support. The of the groove wall 12 enclosed Kedernut serves to accommodate a piping, with the awning fabric on the hollow shaft 10 is attached.

As 14 shows the clamping bush 8th a corresponding Kedereingriff 84 on which a gap in which the counter-wedge section 82 forming Spreizsegmentring forms and up to the ring section 81 extends.

The outer, rotatable clamping sleeve 5 is doing over the carrier neck 6 pressed, which in 9 is shown in detail. The carrier neck 6 has a bearing journal or journal section 61 on, with which he in the as Kugelkalottenlager 2 . 3 trained side bearing 2 . 3 on the side panel 1 is supported. The journal 61 again has a hexagonal recess at the front 63 on, at which during assembly of the axle cap module on the winding shaft 10 a tool can be attached.

To the journal section 61 closes in winding shaft axis direction inside over an annular, radial wall portion 65 a carrier body 62 on, which has a conically widening axially inward outer circumference. This is a plurality distributed over the circumference, a total of concentric arranged to the winding shaft axis and along the winding shaft axis extending guide grooves 75 formed radially inward, the corresponding plurality of inner peripheral side in the radial direction inwardly projecting fins 54 on the outer clamping bush 5 is assigned, with the Finns 54 correspondingly likewise winding shaft coaxial extend, see 7 , About in the guide grooves 64 engaging Finns 54 is the carrier neck 6 transmitting torque, but with degree of freedom of movement in winding shaft axis direction in the outer clamping bush 5 guided, so that when applying a torque to the engaging portion 63 the outer clamping bush 5 is twisted, whereas the inner clamping bush 9 is held.

The outer clamping bush 5 has in accordance with the cone shape of the carrier body 64 on the inner circumference side, an inner circumferential surface which conically tapers outward in the direction of the winding shaft axis and from which the fins are tapered 54 protrude. This results in a good self-centering of the carrier nozzle 6 in the outer clamping bush 5 and a backlash-free storage when the carrier neck 6 over the Ausschubfeder 7 in his out of the hollow shaft 10 extended operating position is biased outwards.

The inner clamping bush 9 further points, see 8a , a support floor 91 on, on which the Ausschubfeder 7 can support with its inner end. The carrier neck 6 has one to the support floor 91 towards open spring guide cavity on the axial outside of which one of the support base 91 in the winding shaft axis outwardly spaced inner shoulder on the annular, radial wall portion 65 located, at which the Ausschubfeder 7 can support with its outer end, causing the carrier neck 6 with its cone-shaped carrier body 62 against the on the outer sleeve 5 provided inner cone is pressed. The guide grooves formed in the carrier body 64 In this case, in each case have a wall forming the groove flanks and the groove base and can thus simultaneously on their inside in Radylichtung side as a peripheral enclosure of the Ausschubfeder 7 serve, which is the Ausschubfeder 7 in the axial direction and a buckling of the Ausschubfeder 7 prevented.

The journal 61 is there, as in particular from the 3 to 6 indicates, via the side bearing 2 . 3 on the side panel 1 or the visor cap 1 the vertical awning supported, which in turn is part of a side bearing module 2 . 3 . 4 is that in the 16 - 19 is shown in detail and with the side panel 1 of the box is connected.

The storage module 2 . 3 . 4 has one on the side part 1 fixed bearing plate 3 on, at the an outer ring 31 designed as a plain bearing 2 . 3 for the journal 61 is trained. The journal 61 is in a bearing inner ring 2 of the plain bearing 2 . 3 taken, in turn, in the bearing outer ring 31 the bearing plate 3 is received rotatably.

The inner ring 2 is designed as a spherical cap. That means that its the outer ring 31 facing outer circumference has a spherical segment-shaped contour. Accordingly, the inner ring 2 facing inner circumference of the outer ring 31 the bearing plate 3 also a spherical segment-shaped contour, so that the inner ring 2 can swing out of the normal plane to the winding shaft axis, see 5 ,

This is with regard to the assembly of the winding shaft 10 advantageous, which in as in 5 shown pivoted inner ring 3 set at an angle to the horizontal and with the bearing pin 61 in the inner ring 2 can be plugged. Subsequently, the winding shaft 10 then as by the arrow in 5 be indicated with its opposite end pivoted upwards. Before this counterpart his seat on the side part 11 ( 1 ) is then reached, as indicated by the arrow in 6 indicated, the winding shaft 10 compressed or the carrier neck 6 by pressure on the winding shaft 10 against the side panel 1 in through the two clamping bushes 5 . 9 formed inner bush 5 . 9 pushed in, so that the winding shaft 10 with in the spherical cap stock 2 . 3 already taken journal 61 can bring in their horizontal position, wherein the opposite end of the winding shaft so on the side part 11 passes by. Then then the over the winding shaft 10 and the Ausschubfeder 7 on the carrier neck 6 and the side part 1 applied pressure can be removed again - see 4 - whereby the Ausschubfeder 7 relaxed and the carrier neck 6 expands outwards and the winding shaft thus in its operating position between the two side panels 1 . 11 telescoped.

The carrier neck 6 with the molded journal 61 can be between one in the 3 and 4 shown operating position of the winding shaft 10 and one in 6 shown assembly position in the inner sleeve 5 . 9 and thus in the winding shaft 10 move. In the operating position is the journal 61 much further over that with the carrier neck 6 provided shaft end of the winding shaft 10 forming hollow shaft 10 over than in the assembly position.

To prevent the winding shaft 10 is undesirable compressed during operation and thereby from their storage on the two end-side panels 1 . 11 falls out, is doing a backup device 4 . 5 provided on the one hand on the side bearing module 2 . 3 . 4 provided safety slide 4 includes and on the other hand, an axially outwardly facing, annular abutment surface on with the support sleeve 6 provided shaft end of the winding shaft 10 ,

The annular abutment surface is in this case on an end-side, annular flange or cylindrical projection or stop ring 51 on the outer clamping bush 5 provided, wherein the outer clamping bush 5 as part of the axle cap module firmly in the winding shaft 10 is anchored.

The safety slide 4 is height-adjustable on the bearing plate 3 taken and has one to the winding shaft 10 in the winding shaft axis direction projecting counter stop pin 41 with a stop surface facing the counter stop surface. In a secured position, in which the counter stop pin 41 with its counter stop surface at the radial height of the annular abutment surface on the outer clamping bush 5 is a compression of the rotatable in the operating position winding shaft 10 or an impression of the carrier nozzle 6 in the inner sleeve 5 . 9 prevented, see 3 ,

The safety slide 4 is like arrow in 3 indicated höhenverschieblich on the bearing plate 3 added. When the safety slide 4 from his in 3 shown securing position in the in 4 shown release position is shifted upward, also moves the counter stop pin 41 upwards and thus in a height which is outside the radial position of the abutment surface having, end stopper ring 51 on the outer clamping bush 5 is located, see 4 , In the secured position - 3 - On the other hand, only a narrow slot remains between the abutment surface of the end-side annular flange 51 the outer clamping bush 5 and the counter stop surface on the counter stop pin 41 of the safety slide 4 ,

The safety slide 4 has one the bearing outer ring 31 annularly surrounding captive securing section 42 with a slightly elongated opening in the vertical direction, through which the bearing outer ring 31 sticks out, leaving the safety slide 4 is vertically displaceable between its securing position and its release position. To the captive protection section 42 is the upper side of the winding shaft projecting counter-stop pin 41 molded and underside a vertically down led operating portion 43 , The operating section 43 has on its underside a 90 ° angle in Wickelwellenachsrichtung inwardly projecting, horizontally extending operating tab 45 on, at the fitter the circlip 4 for the purpose of height adjustment can take.

The safety slide 4 is displaceable on the bearing plate 3 added. For this purpose, it has on the one hand at the lower end of the operating section 43 one opposite to the operating tab 44 protruding latching tab 45 on, with whom he is in his safety position on a lower-shoulder 32 the bearing plate 3 comes to rest and in its release position - see 4 - In a corresponding receiving groove in the bearing plate 3 , At the top of the captive seal section 42 engages behind the safety slide 4 also the bearing plate 3 and points to the winding shaft 10 opposite rear side of the bearing plate 3 two downwardly projecting legs of a locking fork 46 on, which one there from the bearing plate 3 protruding locking pin 33 embrace.

Changes and modifications of the illustrated embodiment are possible without departing from the scope of the invention.

So show the 12 and 15 on the one hand and 13 and 15a on the other hand, two alternative clamping bushes 8a respectively. 8b , which can be used if a structurally identical clamping element 5 . 6 . 7 . 9 to be used for winding shafts with different diameters. It would also be possible from the clamping element 5 . 6 . 7 . 9 and a plurality of clamping bushes 8th . 8a . 8b to deliver existing axle cap module, which clamping bushes 8th . 8a . 8b all have different outer dimensions, but the same internal dimensions. It would also be conceivable to add further alternative clamping bushes with deviating outer contours, for example a hexagonal or octagonal outer contour, in order to make it possible to use the axle cap module not only in the case of vertical awnings but also on roller shutter lifting shafts.
