EP2896764B1 - Retention system for railing panels and method for adjusting the vertical inclination of railing panels - Google Patents

Description

The invention relates to a system for holding railing panels, in particular a holder for the plates of a glass frame railing, as well as an insert that can be inserted into a preferably vorzusehendes holding profile. The system and its aforementioned components are particularly suitable for mounting free-standing all-glass railing panels to building parts. The invention further relates to a method for adjusting the vertical inclination of a railing plate.

More recently, railings are increasingly being used in which all-glass railing panels are used, which are largely free-standing and are used only with their lower edge in a anchored to a structural part holding profile. Here, not only the retaining profile must be securely anchored to the structure. These heavy glass plates themselves must be firmly held in the retaining profile and can absorb enough forces to serve as a reliable fall protection can. The forces acting on the retaining profile via the glass plate, for example, if one or more persons lean against the railing, due to the lever ratios can be significant.

At the same time, such all-glass railings are regarded as design objects and high demands are placed on the visual complacency and the quality impression of such a railing. One aspect which is of great importance in this context is that the numerous railing panels arranged side by side in such a railing must be precisely aligned with one another during installation, so that a railing extending over a relatively long distance with its numerous adjacent individual panels as a whole gives a coherent overall picture. Although the retaining profiles and the railing plates can be produced with narrow tolerances, in particular the structural parts to which the retaining profiles are mounted often do not extend sufficiently so that adjusting the vertical inclination of the railing plates is necessary so that the railing plates are aligned with one another along the railing profile are aligned. It should be noted that even a small vertical tilt deviation on the lower edge of the railing panel used in the holding profile relative to the adjacent railing plate can be potentiated at the upper edge of the railing plate because of the geometric conditions and can have great effects.

To enable precise adjustment of the vertical tilt of all-glass railing panels, various approaches are known. The DE 103 38 816 B3 discloses the possibility of pivoting the retaining profile with respect to a base profile anchored firmly to the structure. The DE 10 2006 028 766 A1 In contrast, describes the possibility of providing a horizontally adjustable glass plate storage at the bottom of the anchored to the building part holding profile, on which the glass plate is seated with its lower end edge. A similar approach describes the DE 10 2009 008 307 A1 , Here, the alignment of the glass plate via wedge-shaped clamping spring elements, which can be driven at the top of the holding profile between the glass plate and retaining profile is realized.

Other systems for adjusting the vertical inclination of railing panels are from the publications DE 20 2013 104 330 U1 . US 2010/0307082 A1 and WO 2011/095779 A2 known.

In order to realize the aforementioned approaches, complex constructions of the holding profiles and a plurality of components are required. For example, adjustment screws are used for the adjustment of adjusting elements, for which in turn corresponding threads, bores or other material recesses are to be provided. The components must be in the support profiles and / or the support profiles must be in basic profiles, against which they are then adjustable, place, which makes the known systems unnecessarily wide and therefore optically expansive. Also, the preparation or pre-assembly of such Haltesyste me due to the large number of interacting components consuming. Not least, the known approaches require additional quality assurance measures and a more complex storage logistics. Also, the effort for fitters who have to assemble such a system at the site, relatively high. In particular, can be in the known systems, the railing plates after their insertion into the disc holder is not set by a freely selectable page, which is especially disadvantageous when the railing primarily as a fall protection on a balustrade, a balcony or other on-site projection is to be used and the access to the one standing on the handrail person facing free side of the disc holder is blocked by the railing plate used.

A disadvantage of the known systems is also that problems or increased effort during installation may arise if the displacement of a retaining profile to the adjacent retaining profile due to the construction is so large that the glass plates can not use holding profile across. Finally, the required structural details (e.g., bores, threads, or other recesses) may adversely affect the structural integrity of the retention profile, and there is an increased risk of component failure.

This effort appears in the light of the fact that the adjustment options offered by the known systems are basically never needed again after a railing installation has been completed once.

Finally, it has to be considered in the systems known from the prior art that they do not permit non-destructive and removal and reuse of individual components. This is especially true for so-called wet systems, in which the glass plate is firmly connected to other components of the adjustment mechanism, for example by an adhesive or a potting compound. The adjustability of such systems, in particular the Nachkorrigierbarkeit, characterized more limited than is the case with dry systems, at which the individual components can be removed at any time, separated, (partially) replaced and reassembled. The object of the invention is therefore to provide a system for supporting railing panels, in particular all-glass railing panels, and its components, which largely minimizes the disadvantages described above. The system should be easy to manufacture, get along with few components, enable a robust mounting of the railing panels on the building, be easy to install on site and allow easy and preferably reversible adjustability of the vertical inclination of the railing panels.

The invention provides for solving this problem, a system for holding railing panels on a building part according to claim 1 or a method according to claim 13, wherein received from a plate receiving a railing plate and within which it can be firmly clamped, available in which a Drehpol (P) is provided within the disc holder and on the side of a flat side of the railing plate, around which the railing plate can be pivoted for the purpose of their vertical orientation in their fixation in the holding profile.

The system for holding the railing plate preferably has a retaining profile, which forms the plate holder. The plate holder can also be embedded or incorporated directly into the building when using a sufficiently strong and resilient construction material. For example, it is conceivable that the plate receptacle be formed by a receiving groove cut or cast directly into a sufficiently strong concrete into which the railing plate is directly inserted.

The raised pivot pole preferably projects laterally into the plate receptacle, so that the pole of rotation after insertion of the railing plate into the plate receptacle facing flat side of the railing plate (Drehpolseite) with the Drehpol during the tightening of the railing plate in the retaining bar directly or indirectly comes into contact. In this case, the raised pivot pole projects preferably from the holding profile or an insertion part inserted into the holding profile into the plate receptacle.

Alternatively it can be provided that the raised of the Drehpol is formed on a flat side of the railing plate (the Drehpolseite), in particular so at their after proper insertion into the disc tray dipping lower edge portion. In this case, the rotational pole comes after insertion of the railing plate and during fixing or tensioning of the railing plate in the holding profile with the holding profile or the structure that forms the plate holder, directly or indirectly in contact, so when using a holding profile in particular with the disc holder defining material area of the holding profile. The Drehpol can be arranged for example on a Drehpolplatte or a Drehpolaufsatz, which or attached to the railing plate, in particular glued or clamped.

The Drehpol thus forms a raised contact point, which defines during the fixing of the railing plate in the disc holder a extending along the railing axis of rotation about which the railing plate can be pivoted for the purpose of their vertical orientation in their fixation in the holding profile. Furthermore, the clamping forces, which are applied on the clamping side facing away from the rotary pole side of the railing plate via clamping parts for fixing the railing plate in the retaining profile, are supported via the rotary pole.

The fact that the railing plate side or the material of the holding section defining the plate holder can directly or indirectly come into contact with the rotating pole means that the railing plate material or the material region of the holding profile defining the plate holder rests either directly (directly) on the material forming the rotating pole or between the material of the railing plate or the material of the holding profile defining the plate holder and the material forming the rotating pole at least one further intermediate layer may be provided (indirect concern). The latter may be particularly useful when the Drehpolmaterial is metal and direct contact between the metal and the railing plate material (preferably glass) should be avoided.

The particular unilaterally provided on one side of the disc holder and protruding into this Drehpol can be formed by a series of individual punctiform, along the plate holder provided at intervals material elevations. However, the rotary pole is preferably designed as an elongated, bead-shaped elevation and projecting laterally into the plate receptacle and extending in the longitudinal direction over at least part of the plate receptacle. The latter is preferred because this results in a line contact between railing flat side and the survey forming the pole, so that selective voltage peaks in the railing plate material can be better avoided.

It can be provided that the rotary pole is integrally formed on a side wall of the retaining profile cross-section forming the plate receptacle. In particular, the rotary pole can be formed by the material of the holding profile itself and be integrally formed as a material integral, integral part of the holder profile. The holding profile is usually an extrusion profile, so that the Drehpol can be extruded in the production of the holding profile together with this.

In order to avoid subsequent direct contact of the metal of the holding profile with the railing plate material, a protective layer may be provided on the railing plate, for example a metal or plastic layer applied in the region of the lower edge of the railing plate side projecting into the plate receptacle, for example onto the railing plate surface can be glued on.

Another way to avoid the direct contact of the railing plate material with the metal of the holding profile, is the Drehpol on a in the disc holder Provide the Einlegteil to be used in the holding profile, in particular material einstückormig to this form. Such an insert has on the intended installation to a flat side of the railing plate side facing the raised Drehpol that protrudes laterally into the disk holder after insertion of the insert into the disk holder, so that the Drehpol facing railing plate side (Drehpolseite) after insertion of the railing plate in the disc holder with the Drehpol indirectly or directly comes into contact. This insert may be made of a plastic, the material properties, in particular material hardness, is selected so that the later material pairing and any damping properties are taken into account in the contact area.

Through experiments, an embodiment has been found to be particularly advantageous in which the Drehpol forming opposite to the adjacent, adjacent surface raised contact point of one or more patch soft plastic parts is formed, which are mounted on the part forming the Drehpol. Such a soft plastic part may in particular be formed by a soft plastic strip such as a (rubber) cord or a (rubber) profile strip. At the component carrying the soft plastic part, a receptacle adapted to the soft plastic part, in the case of using a soft plastic strip, in particular a groove, can be formed, is inserted into the soft plastic part and fixed, for example by clamping or gluing.

To adjust the vertical orientation of the railing plate and firmly clamp the railing plate in the retaining profile, the system provides one or more clamping parts to be inserted and / or beat on the Drehpol the railing plate opposite railing plate side (clamping side) between the holding profile and railing plate. Preference is given to several clamping member sets with two clamping parts, in particular with in each case an upper clamping part and a lower clamping part, are used, which are arranged offset from one another, so that the lower of the two clamping parts remains accessible after their intended positioning. The clamping parts are preferably wedge-shaped and have a wedge shape adapted to the nip.

It has proven to be advantageous to provide the Drehpol in the lower half of the disc holder. Through a targeted use of the clamping parts, the vertical tilt of the glass plates can be set most effectively.

For the purpose of bracing the railing plate in the holding profile, the clamping parts are driven between the side facing away from the Drehpol railing plate side (clamping side) and the holding profile. Depending on the positioning of the clamping parts, a different vertical inclination of the railing plate sets.

The invention thus enables a method for the vertical alignment of a railing plate used in the disk holder of a holding profile, in which after inserting the railing plate in the disc holder only one or more clamping parts in the disc holder between the side facing away from the rotating pole rail side (clamping side) and the clamping side facing and the plate holder must be taken with the forming wall of the holding profile and / or inserted, wherein a change in the vertical orientation of the railing plate is only to vary the vertical clamping part position. As described above, before inserting the railing plate, an insert part, on which the rotary pole is formed, can be inserted into the retainer profile.

The described system for supporting railing panels or the method for adjusting the vertical inclination of the railing plate is thus characterized by a very simple structure with few components. The assembly costs are low. By eliminating the need for drilling or similar material removal in the support profiles for the purpose of adjusting the vertical tilt, the structural integrity of the support profiles remains unaffected. In addition, the system meets the highest optical standards, because basically no optically disturbing Screws or other actuators as well as the actual holding profile no additional profiles use find that provide a rather rugged appearance or would be expensive to hide by cover strips or the like. Components or mechanisms that involve the risk of component failure or malfunctions are basically nonexistent. In order to adjust the vertical inclination of the railing panels, the construction must be accessible only on the clamping side of the railing panel after inserting the railing panel into the panel receptacle. The design as a pure dry system ensures a simple and non-destructive interchangeability of the individual components and their reusability. A correction of the railing plate alignment or the targeted replacement of certain individual components is possible at any time.

FIG. 1 shows a comparison of a used in a holding profile 1 and tightly clamped all-glass railing panel 2 in three different positions (a), (b) and (c), each with different vertical inclinations, based on the respectively at the lower end of the railing panels 2 attaching center plane M and different position of the railing plate to the mounted on the upper plate receiving opening sealing strip 3 can be followed.

The retaining profile 1, which is preferably an extruded aluminum hollow profile, has a U-shaped, top-side open plate receiving, in which the railing plate 2 is inserted with its lower edge.

On the in FIG. 1 right side of the U-shaped plate holder is an insert 4 inserted, which in detail in Figure 2a and 2b is shown. This insert 4 is L-shaped and has a lower horizontal leg 5 and a lateral vertical leg 6. The lower horizontal leg 5 is in accordance with the intended positioning in the retaining profile on the bottom of the disc recording and preferably has a slight upward curvature, which is able to absorb the heavy weight of the railing plates easily and prevents direct contact of the glass plate with the holding profile. In addition to avoiding direct contact between glass and metal, this also has the advantage that the typically multi-layer laminated safety glass panes can not draw water and the risk of delamination is largely minimized, which is particularly desirable in outdoor railings used. The vertical leg 6 rests with its side facing away from the disk recording on the support section 1.

The plate receptacle has - starting from the base of the U-shaped plate receiving channel - a height H. At about the height h (it is h <½ H, preferably h between ¼ H and ½ H) is located on the insert a laterally projecting into the disc holder Survey 7 or bulge, which rests upon proper installation of the railing plate in the retaining profile on the surface of the railing plate and forms a Drehpol P with the contact point by which the railing plate can be pivoted to adjust your vertical inclination. The rotary pole P facing side of the railing plate is referred to as Drehpolseite. How out FIG. 2a As can be seen, the bulge or elevation that forms the rotating pole P extends 7 in horizontal direction over the entire length of the insert 7, so that there is a line contact between railing plate and insert.

In the nip on the side facing away from the P pole side of the railing plate 2 (clamping side) are for fixing the railing plate and adjusting their vertical inclination, a first, lower clamping part 8 'and a second, upper clamping part 8 "inserted or taken.

As from the different in FIG. 1 As shown in positions (a), (b) and (c), the vertical inclination of the railing plate can be achieved by varying the vertical positioning of the clamping parts 8 ', 8 "while the railing plate is in position (a) by a very low-fitting lower clamping part 8 "and a fairly high-fitting upper clamping part 8" relative to the median plane M is still slightly inclined to the left, tilts the railing plate - as from positions (b) and (c) can be seen - at higher arranged lower clamping part 8 "and one on arranged below clamping part 8 'increasingly to the right.

Due to the down slightly tapered plate holder and the wedge-shaped clamping parts 8 ', 8 "can be very high clamping forces and a very stable mounting of the railing plate in the holding profile realize.

Figure 3a and 3b show the first, lower clamping part 8 'and Figure 4a and Figure 4b In particular on the upper clamping part 8 ", but if necessary also on the lower clamping part 8 ', notches 9 can be provided on the edge, which point downwards when installed as intended and are engaged behind by a suitable tool can, so if necessary, the position of the clamping member in the nip easier to correct or it can be more easily removed from the nip.

To install a longer railing preferably several inserts 4 and clamping parts 8 ', 8 "provided along a railing plate, but it can also a longer insert 4 may be provided that can extend over the entire length of a railing plate. For different railing plate thicknesses or for different widths of the plate receiving clamping and insert parts can be offered with different thicknesses, which are adapted to the width of the respective nip.

FIG. 5 shows a slightly modified embodiment of the in Figure 2a and 2b shown insert, in which the rotary pole is formed by a provided on the insert soft plastic part in the form of a rubber cord 10 which is inserted into a receptacle provided on the receptacle in the form of a groove. This embodiment has proved particularly suitable for applications in which the railing plate is subjected to frequent alternating loads, which are aligned transversely to the railing direction. The high effective between the handrail plate and the soft plastic part effective friction coefficient and the if little compressibility and damping properties of the soft plastic part prevent a possible loose shaking the braced in the plate receiving railing plate in cases of particularly unfavorable acting exchange loads.
