Longitudinal guide rail for roller shutters

The invention relates to a longitudinal guide rail for roller shutters, in particular for those with armor made of plastic, with a cross-section essentially U-shaped profile for the longitudinal guidance of the roller shutter therein, the front and
Back legs or the web of the U-profile are prepared for fastening on the building side.

Longitudinal guides for roller shutters of this type are used in window or door openings of buildings. For this purpose, the U-shaped profile of the longitudinal guide rail is fastened, preferably screwed, either with its web to the window or door reveal itself or with its back leg to the Rahitien wood of the window or door held on the reveal. The fastening of the U-profile to the reveal itself requires

Through the longitudinal guide rail according to the invention, the unavoidable gap between U-profile and reveal completely covered. The plastering of the masonry can extend to the front panel are executed. For further embellishment, the front panel can even be partially integrated into the plaster be included. In both cases, a clean plaster edge can be easily and flawlessly on the front panel raise. The cover of the gap also hides any defects in the reveal. This takes into account needs when using the longitudinal guide rail according to the invention the soffit is no longer of such good quality and that it is carried out carefully. On plastering the The reveal in the area between the timber frame and the outer edge of the masonry can even be dispensed with entirely. So be additional labor costs saved. |

In a preferred embodiment of the invention, the front panel extends with its longitudinal edge at least up to the free longitudinal edge of the fore leg and covers the fore leg over its entire width. As a result | uniform facing is achieved on both sides of the window or door. The U-profile of the longitudinal guide rail is no longer visible. From the free longitudinal edge of the U-profile to the plaster edge of the masonry extends a continuous, uninterrupted veneer surface, which can optionally be colored, for example in the color of the Frame wood. Despite the quick and time-saving installation, the window or door with the installed longitudinal guide rails shows for the roller shutter an accurate appearance with a high level of craftsmanship.

In a further embodiment of the invention corresponds

the overhang of the front panel is approximately the width of the leg |

U of the fore leg of the U-profile. As a result, the longitudinal guide rail meets practically all installation requirements and different installation conditions,

7827131 04.0179

even if a roller shutter is retrofitted to a building.

In a further embodiment of the invention, the front panel is designed as a preferably one-piece plastic part, in particular made of hard PVC. As a result, on the one hand, an efficient production of the front panel is made possible and, on the other hand, a weather-resistant product ^{f is} created. By adding color additives accordingly, the front panel is given the desired color appearance without additional paint and its constant, weather-related renewal.

A particularly advantageous embodiment of the invention results from claim 5. By the non-positive and / or form-fitting Interlocking fasteners allow the front panel in an extremely easy-to-assemble manner attach to the ü ~ profile. By appropriate configurations of the connecting elements, as they are the subject further embodiments listed in the subclaims of the invention, the front panel can simply be clipped onto the U-profile mounted on the frame wood. All connecting elements between the front panel and the U-profile, as well as all fasteners for fastening the U-profile on the frame wood or the reveal are covered by the front panel and are completely invisible. Also the dismantling the longitudinal guide rail is ensured. By simply pulling the front panel off the U-profile the fastening means, preferably screws, are exposed for the U-profile.

A particularly advantageous embodiment of the invention is given according to claim 6. The hook-like cross-section, the free longitudinal edge of the fore leg overlapping fold of the front panel has a threefold function to. On the one hand, this fold represents one of the connecting elements

to hold the front panel. On the other hand, the fold covers the longitudinal edge of the front leg of the U-profile and thus improves the appearance of the longitudinal guide rail also from an angle of view obliquely from the front of the roller shutter. Thirdly, the fold is suitable in connection with further embodiments of the invention according to further subclaims at the same time as a carrier for a damping strip, the a rattling of the roller shutter in the U-profile largely dampens or completely prevents. Such a damping strip is preferably used in the manufacture of the rigid PVC front panel in the same operation from soft PVC at the same time upset.

Another advantageous embodiment of the invention results from claim 9. By the arrangement of further force and / or form-fluid connecting elements and / or recordings in the The area of the web-side longitudinal edge of the fore leg results in connection with the hook-like cross-section Falz em the longitudinal edge of the front panel a secure and permanent attachment of the front panel to the U-profile, which also allows dismantling of the longitudinal guide rail. Both putting on and removing the front panel the or from the U-profile is done with a few simple steps in seconds. The assembly of the longitudinal guide rail is therefore no more time-consuming than the assembly of previously known longitudinal guide rails.

A particularly advantageous embodiment of the invention results from claim 17. The longitudinal grooves provided allows a clean dismantling of the longitudinal guide rail even if parts of the front panel are in the plastering of the Masonry are included, without the slightest damage to the plaster. In this case, along the Longitudinal grooves, which represent a predetermined breaking point, severed the front panel. Then the front panel can be removed from

In Fig. 1, the longitudinal guide rail is in its spatial arrangement in the building and in connection with parts of the Shutter curtain shown, with all parts cut horizontally. Those that do not belong to the longitudinal guide rail Parts like masonry 10, frame wood 11 one Windows or a door and roller shutter 12 are for the sake of clarity with thinner lines and partially drawn in dash-dotted lines.

The longitudinal guide rail for roller shutters, especially for those with armor 12 made of plastic, has a cross-sectionally essentially U-shaped profile 13, in the following U-profile called, on. The U-profile represents the longitudinal guide of the roller shutter 12 during its vertical movement in the direction of the in Fig.1 drawn arrow and across it safely. The U-profile 13 has a fore leg in a known manner 14, a back leg 15 and one of the two legs 14 ' and 15 connecting web 16. The two legs 14 and or the web 16 are prepared for fastening on the building side. It is in Fig. 1, the U-profile 13 on the Frame wood 11 attached. For this purpose, through holes for screws 17 are provided in the rear leg 15, with which the U-profile is screwed to the frame wood 11. To use a screwdriver are in the fore leg aligned with these through holes in diameter larger openings provided. For the sake of clear illustration I, these openings are not shown in FIG. 1.

On the U-profile 13 is a longitudinal front panel 18, preferably releasable, held. The front panel 18 stands laterally over the web-side longitudinal edge 19 of the fore leg 14 over. This overhang is dimensioned so that the front panel 18 at least when the U-profile 13 is mounted up to the longitudinal edge 20 of the door or window reveal 21 extends. The protrusion dimension preferably corresponds to the front panel about the width of the fore leg 14. Up

- 13 -

on the other side, the front panel 18 extends with its longitudinal edge 22 at least as far as the free longitudinal edge of the fore leg 14 and thus covers the fore leg 14 over its entire width. When in Fig. 1 illustrated arrangement of the longitudinal guide rail on the frame timber 11, which in turn on the soffit 21 of the masonry 10 is held, the front panel 18 extends partially over the protrusion dimension specified above Masonry 10. As a result, part of the front panel 18 is included in the plaster 24 applied to the masonry 10. A clean plaster edge 25 can be found on the front panel 18 when the plaster 24 is applied to the masonry create.

The front panel 18 is preferably a one-piece plastic part, in particular made of hard polyvinyl chloride. (PVC). Front panel 18 and U-profile 13 preferably have integrally molded connecting elements 26 and / or associated therewith Recordings 27 on. These connecting elements 26 and / or receptacles 27 engage non-positively and / or positively or to each other and thereby hold the front panel 18 on the U-profile 13. Such a connecting element 26 is of a hook-like fold 28 in cross section is formed on the longitudinal edge of the front panel 18. This fold shows a grip ungsrand 29, which engages over the free longitudinal edge 23 of the fore leg 14 in a clamping manner up to the inside thereof. A damping strip 30, preferably made of soft polyvinyl chloride (PVC), is attached to the encompassing edge 29. This damping strip 30 stands with at least one damping lip 31 over the inner guide surface 32 of the fore leg 14 into the interior of the U-profile 13 over. In order to accommodate the encompassing edge 29 and the damping strip 30, the fore leg 14 is in the area of his free longitudinal edge 22 angled approximately step-like to the outside to form a step space 33. Inside this Step space 33 is the encompassing edge 29 with damping strips

arranged. The damping strip 30 is expediently when producing the front panel 18 on this same with applied, e.g. glued on or the like.

More of the above-mentioned non-positive and / or form-fitting Connecting elements 26 and / or receptacles 27 are on the one hand on the front leg 14 of the U-profile 13 and on the other hand, arranged on the front panel 18 in the region of the web-side longitudinal edge 19 of the front leg 14. It goes without saying that these connecting elements and / or receptacles 27 are also arranged on the web 16 of the U-profile 13 could be. These connecting elements 26 are designed as spring elements which latch to one another in the manner of a clip.

As with the longitudinal guide rail according to FIG. 1 - but also in the exemplary embodiments according to FIGS. 2 and 3 - to be seen is, carries the front panel 18 as a spring element at least a resiliently rebounding spring clip 35 protruding beyond its rear side 34 with a barb-like locking lug The U-profile 13 carries a locking web 37 facing the rear side 34 of the front panel 18 with an associated locking lug 38. The two locking lugs 36 and 38 of the spring clip or locking web 37 engage behind one another. For improvement the locking point - as can be seen in Fig. 1 - on the one hand the spring clip 35 of the front panel 18 and on the other hand the Locking web 37 of the U-profile 13 each has a plurality of locking lugs grouped one behind the other in cross-section to form approximately a sawtooth profile 36 and 38 respectively. The spring clip 35 with locking lug 36 and the locking web 37 with locking lug 38 extend strip-shaped Over the entire length of the front panel 18 and the U-profile 13. The locking web 37 ends with its to Front panel 18 pointing outer edge at the same height as the outer contact surface 39 of the fore leg 14 for the Front panel 18. The locking web 37 runs with his

7827131 01/04/79

- 15 -

Outer edge in a common, to the front panel 18 about parallel plane and forms a support system for the front panel 18.

The front panel 18 has at least the one that protrudes beyond the web-side longitudinal edge 19 of the front leg 14 Surface area has a certain surface roughness, which prevents the adhesion of application materials such as plaster 24 in Fig. 1, significantly improved. This simplifies the inclusion of a surface part of the front panel 18 in FIG the exterior plaster. At a transverse distance from the web-side longitudinal edge 19 of the fore leg 14 runs on the outside the front panel 18 approximately parallel to the longitudinal edge 19 a Longitudinal grooves 40. These longitudinal grooves 40 serve as a predetermined breaking point for severing the front panel 18 possibly dismantling of the longitudinal guide rail. This prevents the front panel 18 from being pulled off the U-profile. the plaster 24 of the masonry 10 is damaged or broken off. The longitudinal grooves 40 can be practically in any any area of the outside of the front panel 18 can be arranged (Fig. 1 - 3). Preferably it is located but on that surface section of the front panel 18, which extends in the transverse direction beyond the fold 28 as well as the Connecting elements 26 extends beyond the web-side longitudinal edge 19 of the fore leg 14, and here in particular in the area of the gap which, when the U-profile 13 is installed, is between the web 16 of the U-profile 13 and the soffit 21 of the Masonry 10 results (Fig. 1).

The longitudinal guide rails according to the further exemplary embodiments in FIGS. 2 and 3 differ from that according to FIG. 1

only in the formation of the non-positive and / or positive connection elements 26 and / or receptacles 27 between the U-profile and front panel 18. The same components are therefore provided with the same reference numerals.

In the embodiment in FIG. 2, the fore leg 14 of the U-profile 13 on its outside as a non-positive and / or form-fitting receptacle 27 an approximately channel-like depression 41. Of the wall webs 42 on both sides of the recess 41, at least one here both, the above-described locking web 37 with locking lug 38. The locking lugs 38 of the two of the wall webs formed locking webs 37 are of two locking lugs 36 of the now two-part spring clip 35 on the back 34 of the front panel 18 reached from behind. The recess 41 also extends over the entire length in the form of a strip Length of the U-profile 13. The modification of the longitudinal guide rail according to FIG. 3 compared to the longitudinal guide rail in Fig. 1 is even more insignificant. Here, the spring clip point on the rear side 34 of the front panel 18 and the Ra.steg 37 on the outside of the fore leg 14 not a sawtooth profile as in FIG. 1, but only one in each case single locking lug 36 and 38, which engage behind one another.

The assembly of the longitudinal guide rail according to the invention is particularly easy. It can be done at the factory at the manufacturer of the windows or doors, at the construction site or afterwards take place in the finished structure. For this purpose, the U-profile 13 is first of all attached to the frame timber 11 with its rear leg 15 attached. For this purpose, 15 screws 17 are to be screwed into the frame timber 11 through the through holes mentioned in the rear leg. The distance between the web 16 of the U-profile 13 and the soffit 21 of the masonry 10 can meet the needs of the roller shutter. A special preparation of the reveal 21 for the assembly of the longitudinal guide rail is not mandatory.

After attaching the U-profile 13 to the frame timber 11 the front panel 18 with its fold 28 on the free longitudinal Edge 23 of the fore leg 14 pushed on transversely to the longitudinal direction of the U-profile 13. After that, the front panel with their connecting elements 26 by pressure on the front panel 18 in the area of the web-side longitudinal edge 19 of the fore leg 14 is clipped into the receptacle 27 on the fore leg. The front panel 18 now covers the gap between the web 16 of the U-profile 13 and the reveal 21 of the masonry 10 completely and still covers a little the masonry 10. Now the masonry 10 is plastered, with the front panel 18 up to the plaster edge 25 in the plaster is involved.

Should the longitudinal guide shaft be dismantled for repair purposes then the front panel 18 must first be severed along the longitudinal grooves 14. This is useful for the plastering 24 is not broken out when pulling off the front panel 18. In the case of front panels 18, which are only up immediately * If the reveal 21 protrude and are not included in the plaster 24, such a cutting is of course not necessary of the front panel 18. After this cutting through of the front panel 18, the part held on the U-profile 13 can the front panel 18 are clipped, the connecting elements 26 and receptacle 27 come out of engagement, and in the transverse direction from the free longitudinal edge 23 of the fore leg 14 can be deducted.

The invention is not limited to the embodiment described above limited. For example, the front panel can be made of different materials, especially aluminum, getting produced. The longitudinal guide shaft according to the invention can also be used for roller shutters whose armor is made of materials other than plastic.
