Description

The invention relates to a wedge profile part for use in a glass railing holder assembly and to a glass railing holder assembly with a glass pane usable as a railing for indoor and outdoor building parts, such as balconies, pedestals, galleries, stairs, terraces and the like, said glass pane having a lower edge. Furthermore, the holder assembly comprises a carrier profile, which is U-shaped in cross-section, for receiving the glass pane as well as the inner and outer edge zones thereof, and for supporting the glass pane and attaching it to the building part. To ensure accurate fixation of the glass pane in the carrier profile in the vertical direction, at least one wedge fixing assembly is provided between an inner or outer lateral cheek, respectively of the carrier profile and the inner or outer edge zone of the glass pane.

The above-mentioned wedge fixing assembly has, on the one hand, attachment legs associated to the carrier profile, which are each arranged on the inside and on the outside of the glass pane arranged, the attachment legs having attachment surfaces opening upwardly in the shape of a wedge, and, on the other hand, fixing wedges clamped between the inner or outer edge zone, respectively of the glass pane and the respective attachment surface of the attachment legs.

In the above embodiment of the wedge fixing assembly, which is known on the market by prior public use, the wedging still needs to be improved in terms of its stability and the fixation accuracy of the glass pane in the vertical.

From WO 2015/145477 a wedge profile part for use in a glass railing holder assembly is known, the wedge profile part comprising a carrier profile, which has two lateral cheeks forming parallel and plane flanks, for a glass pane to be used as a railing, comprising a wedge fixing assembly to be arranged on the inside and on the outside of the glass pane and having attachment legs with wedge-shaped attachment surfaces associated to the carrier profile, and a bottom fixation for the inner and outer edge zones in front of the lower edge of the glass pane, said bottom fixation being formed by a wedging assembly on the wedge profile part, which has a wedge block guided for displacement on the wedge profile part in such a way that the glass pane can be clamped in relation to the inner or outer lateral cheek, respectively of the carrier profile by displacing the wedge profile part in relation to the wedge block.

From US 2010/0205880 A1, a glass railing holder assembly is known in which a glass pane to be used as a railing is held in a wedge fixing assembly only in its bottom region. Said wedge fixing assembly has two wedge blocks arranged on the inside and on the outside of the glass pane, the wedge blocks being clamped by means of a clamping member forming an inner wedge. Said clamping member is actuated by an actuating bolt in a carrier profile. This known assembly needs improvement because of the fact that the glass railing is held only in a narrow edge region. Furthermore, it is impossible to use a universal simple carrier profile as the carrier profile needs to be specially adapted to this known holding system.

From DE 20 2010 016 187 U1 a pane railing is known, in which a spacer is inserted into the gap between the pane and the legs of the carrier profile on the outside of the pane and a wedge body is inserted therein on the inside thereof. A similar design is shown in DE 20 2010 016 190 U1, in which the wedge body is supported on the carrier profile leg via a separate spacer.

The contact surfaces between wedge body and spacer are corrugated.

In the design according to DE 20 2013 104 330 U1, a glass carrier and glass wedges are used for the holders of a glass pane in a U-shaped profile, too. EP 2 896 764 A1 discloses a system for supporting railing panels and a method of adjusting their vertical inclination, wherein an insert on one side of the railing panel has a projection facing the panel and serving as a centre of rotation, wherein when fixing wedges are inserted on the remote side of the railing panel, these are able to pivot about the centre of rotation in such a way that an adjustment of the vertical position of the panel can be carried out. A fundamental problem of the known glass railing holding assemblies lies in the stability of the fixation of the glass pane and the precise adjustability thereof, which should in principle be as good as possible.

To solve this problem, it is provided according to the characterizing part of claim 1 to form the attachment legs of the wedge fixing assembly on wedge profile parts, which are separate from the carrier profile. This embodiment can also be carried out with simple fixing wedges, which are not provided with a bulge and are not corrugated.

Owing to the separate wedge profile parts, the above embodiment of the invention has the advantage that the carrier profile can be any simple structure in the shape of a U when seen in cross-section, such as a welded steel structure or the like. This is then provided with the wedge fixing assembly according to the invention.

According to the invention, a bottom fixation for the inner and outer edge zones is also provided on the wedge profile parts in front of the lower edge of the glass pane. This, together with the wedge fixing assembly, ensures a defined and permanently stable mounting of the glass pane.

The additional wedging assembly forming the bottom fixation has a wedge block guided on the wedge profile part such that the glass pane can be clamped relative to the inner or outer lateral cheek of the carrier profile by a relative displacement of wedge profile part relative to the wedge block.

This type of bottom fixation together with the wedge assembly optimizes the stable support of the glass pane in the carrier profile, which can still be designed as a simple U-profile.

According to a preferred embodiment, the wedge block has a guide groove, which is provided with an undercut and is inclined relative to the main plane of the glass pane in the assembled position, for guiding the wedge block along the wedge profile part, the guide groove being engaged by guide web formed in one piece with the wedge profile part in the manner of a sliding block in such a way that a mutual transverse play is provided for the relative displacement of the wedge profile part in relation to the wedge block. This design ensures that the wedge profile part and the wedge block are already connected to each other prior to assembly, in other words they do not have to be assembled on site. More details concerning the resulting assembly advantages can be found in the corresponding description of the exemplary embodiment.

Alternatively, the wedge block providing guidance along the wedge profile part can also be provided with a dovetailed guide groove one each of its two outer edges extending in the wedge direction, which is engaged by a guide web provided on the corresponding outer edges of the wedge profile part.

Preferably, in the assembled position, the wedge block is supported with its flared end on the base of the carrier profile. This results in a defined position of the wedge block virtually at the lower stop when inserting the wedge fixing assembly between the carrier profile and the glass pane.

According to a preferred embodiment of the glass railing holder assembly, a spacer disposed on the lower edge of the glass pane and serving as an additional mounting aid is provided for centreing the glass pane when being inserted into the carrier profile. Two to three spacers of this type can be clipped into the carrier profile of the glass pane prior to insertion, leaving the latter centred and protected. The spacer may replace the U-shaped bottom seal disposed on the lower edge of the glass pane.

All wedge angles of the fixing wedges, attachment surfaces and wedge blocks are preferably between 5° and 10°. This is a favorable compromise between a sufficient fixing force and stable position of the respective component in the wedged position.

The invention also relates to an improvement of the glass railing holder assembly according to which it is provided that the fixing wedges are provided, at their flared ends, with a nose-like web projection at the edge of the inner wedge surface facing the glass pane. By means of this web projection, a lateral clamping of the fixing wedge is achieved in its assembled position such that a further stabilisation of the holder assembly is achieved. Furthermore, the attachment surfaces of the attachment legs and the outer wedge surfaces of the fixing wedges clamped therewith have a corrugation running transversely to the wedge direction while the inner wedge surfaces of the fixing wedges clamped with the glass pane are provided with an outwardly curved bulge.

The corrugation ensures that the attachment legs are sort of locked with the fixing wedges such that after inserting the respective fixing wedge between the attachment leg and the glass pane, the position thereof is permanently secured in such a way that it is unable to slip out in the opening direction of the wedge. The bulge provided on the inner wedge surface acting upon the glass pane causes said wedge surfaces to be compressed during insertion, causing an increased bias acting on the wedges, which results in an even more improved retaining force for the glass pane. An uncontrolled loosening of the fixing wedges, which are clamped by simple tapping, is thus reliably prevented. The bulge provided on the surface of the wedges facing the glass pane furthermore ensures a defined, angle-independent load transfer.

The basic concept according to the invention of the glass railing holder assembly with all its preferred further developments has the advantage that it is possible to correct the glass angle by means of the fixing wedges, which can be clamped individually. As a result, offset tolerances during assembly and deviations of the carrier profile from the desired shape as well as planarity tolerances of the glass pane can easily be compensated for.

This concerns all embodiments of the invention in which, for example, the attachment legs of the wedge fixing assembly are formed in one piece with the carrier profile. Then, the lower edge of the glass pane is preferably mounted on a bottom seal, which is substantially U-shaped in cross-section, in the carrier profile.

In the aforementioned preferred embodiments, the carrier profile can be equipped with a glass pane in a simple assembly step, which is then fixed in the carrier profile in a vertically accurate manner by means of the holder assemblies according to the invention. The bottom seal provided optionally ensures a resilient as well as tight mounting of the lower edge of the glass pane.

In all of the aforementioned preferred embodiments of the glass railing holder assembly, the distance gap between the glass pane and the respective upper edge of the lateral cheek of the carrier profile can be sealed by means of a sealing strip. In this manner, the entire bottom area of the glass pane within the carrier profile is protected from penetrating moisture.

To optimize the mounting of the glass pane, a respective support bar can be inserted between the lower edge thereof and the base of the carrier profile at least along sections of the glass pane.

The invention also relates to a wedge profile part for use in a glass railing holder assembly having a carrier profile for a glass pane to be used as a railing the general concept of which has already been explained as part of the above glass railing holder assembly. To avoid repetitions, reference is made to the above description of the corresponding components of the wedge profile part configured as the wedge fixing assembly and a bottom fixation. This also applies to the further development of the bottom fixation of the wedge profile part in the form of a wedging arrangement comprising a wedge block.

In a preferred further development of this wedge profile part, the mutually facing attachment surfaces of the guide groove and of the guide web are provided with mutually engaging toothed sections for preventing the relative displacement of the wedge profile part relative to the wedge block in their clamped position. Thus, the fixing effect of this wedging assembly is again optimized significantly in terms of its stability and security to prevent unwanted loosening.

Finally, the wedge profile part may be provided with an engagement groove for a tool to facilitate removal thereof from the carrier profile. Another optimization of the wedge profile part is that wedge blocks thereof are each provided with a chamfer on the outside of their lower flared ends. This chamfer allows inner radii or weld seams on the carrier profile to be bridged.

Another preferred embodiment concerns a wedge profile part, which, together with all its components, consists of a rigid plastic material and is distinguished by a particularly stable, dovetailed connection between the wedge profile part and the wedge block.

The fundamental clamping principle of the glass railing holder assembly, which is used in all embodiments, is to be explained with reference to Fig. 1, said glass railing holder assembly forming a postless glass railing system clamped at the bottom. Said glass railing system can be mounted to balconies, pedestals, terraces and the like using connectors having a corresponding design. In Fig. 1, for example, a balcony parapet 1 is shown to the front side of which the railing is secured by means of corresponding anchoring screws 2. A main component of the glass railing holder assembly is the actual glass pane 3 forming the railing, which consists, for example, of a two-pane laminated safety glass having a thickness of between about 20 and 30 mm.

The lower edge 4 of the glass pane 3 with its inner and outer edge zone 5, 6 is accommodated in a carrier profile, designated as a whole by reference numeral 7, with a substantially U-shaped cross-section, which extends along the length of the glass pane 3. The carrier profile 7 serves to support the glass pane 3 and to secure it to the building part, such as the balcony parapet 1. For this purpose, the carrier profile 7 is screwed, with its inner leg 8, to the balcony parapet 1 using anchoring screws 2.

To anchor the glass pane 3 in the carrier profile 7, a wedge fixing assembly 9 is provided, which is provided between the inner lateral cheek 8 and the outer lateral cheek 10 of the carrier profile 7 on the one hand and the inner and outer edge zones 5, 6 of the glass pane 3 on the other. Fig. 1 shows a wedge fixing assembly 9, which is provided several times at regular intervals along the length of the carrier profile 7 according to the structural requirements.

Each wedge fixing assembly 9 has, on the one hand, attachment legs 11,12 disposed on the inside and on the outside of the glass pane 3 and associated to the carrier profile 7 with wedge-shaped attachment surfaces 13, 14 opening upwardly. A fixing wedge 15,16 is then in each case inserted in the gap 26 between the carrier plate 3 and the inner or outer lateral cheek 8, 9, respectively of the carrier profile 7, the fixing wedge being clamped between the inner or outer edge zone 5, 6, respectively, of the glass pane 3 and the respective attachment surface 13,14 of the attachment legs 11,12 facing the same by light tapping from above.

As can be seen in particular from Fig. 2 taken in conjunction with Fig. 1 and also from Fig. 5, the attachment surfaces 13,14 of the attachment legs 11,12 and the outer wedge surfaces 17 of the fixing wedges 15, 16 clamped therewith are provided with a corrugation 18 running transversely to the wedge opening direction, ensuring that the outer wedge surface 17 securely engages the respective attachment surface 13,14 of the attachment leg 11, 12. The corrugation 18 is preferably in the shape of sawteeth with a tooth depth z of up to 1 mm and a spacing a of the teeth 46 of up to 3 mm.

As shown in Fig. 2, the opposite inner wedge surface 19, which comes to abut against the glass pane 3 is provided with an outwardly curved bulge 20, which provides for an enhanced clamping of the fixing wedges 15,16 in the wedge fixing assembly 9.

For additional stabilization of the fixing wedges 15, 16 in the assembled position shown in Fig. 1, nose-like web projections 21 are furthermore provided at the flared end 22 of the fixing wedges 15, 16 on the edge of the inner wedge surface 19. These provide for an additional clamping of the fixing wedges 15, 16 when a force is acting on the glass pane 3.

In order to guide and support the glass pane 3 by means of a bottom fixation F in the region of its lower edge 4, this lower edge 4 is held by a substantially U-shaped bottom seal 23, which is inserted in a corresponding receptacle 24 in the base 25 of the carrier profile 7. The bottom seal 23 may extend along the entire length of the glass pane 3 or only along sections thereof having a greater or smaller length.

The gaps 26 between the glass pane 3 on the one hand and the upper edges 27 of the lateral cheeks 8, 10 of the carrier profile 7 on the other are sealed by a sealing strip 28, which extends along the entire length of the carrier profile 7.

In the embodiment shown in Fig. 1, the carrier profile 7 is made of an extruded aluminium profile, in which the abutment legs 11,12 of the wedge fixing assembly 9 are formed in one piece with the carrier profile 7.

Deviating from this, the embodiment according to Fig. 3 shows a variation in which the attachment legs 11,12 of the wedge fixing assembly 9' are each formed on wedge profile parts, designated as a whole by reference numeral 29, which are separate from the carrier profile 7.

In this glass railing holder assembly, simple steel profile parts are provided as a carrier profile 7 the lateral cheeks 8,10 of which, which are designed as parallel and plane flanks on the inside, and the base 25 of which are formed by plateshaped steel profile parts welded together. In this case, two wedge profile parts 29 of this type are provided for each wedge fixing assembly 9', namely in each case one on the inside and on the outside. The wedge profile parts 29 are again provided with the attachment legs 11,12 with the attachment surfaces 13, 14, which are formed in the upper half thereof when in the assembled position, and which, in analogy to the embodiment according to Fig. 1, ensure clamping of the glass pane 3 by means of the fixing wedges 15, 16. Although it is shown in Fig. 3 that the attachment surfaces 13, 14 and the corresponding outer wedge surfaces of the fixing wedges 15, 16 are again provided with a corrugation 18, a corrugation 18 and a bulge 20 of the fixing wedges 15, 16 can be omitted in this embodiment.

The wedge angles K of the fixing wedges 15, 16 and of the attachment surfaces 13, 14 relative to the vertical are between 5° and 10°, and may amount to precisely 7°, for example.

For bottom fixation F of the glass pane 3, a fixing and sealing strip 30 is provided in this embodiment, which abuts against the respective inner and outer sides of the edge zones 5, 6 of the glass pane 3 and is inserted in a corresponding receptacle 31 at the lower end of each wedge profile part 29.

The fixing and sealing strips 30 are shaped such as to protrude farther and farther inwardly from the wedge profile part 29 in the direction of the lower edge 4 of the glass pane 3 such that when a pressure is applied thereto, the lower edge 4 of the glass pane 3 is pressed between the two strips of the opposing wedge profile parts 29 until it is supported on the support strips 32 distributed between the wedge profile parts 29 in the longitudinal direction. Finally, it must be added that the wedge profile parts 29 have an inwardly bent support web at their lower end via which the wedge profile parts 29 are supported on the base 25 of the carrier profile 7'. Furthermore, the sealing strips 28 are again provided for sealing the supporting profile 7’ in the upper gaps 26.

Another embodiment of simple carrier profiles 7’ designed as steel profiles with separate wedge profile parts 29' is shown in Figs. 4 to 6. Here, the wedge profile parts 29’ configured as extruded aluminium profiles are again provided, in their upper half, with the attachment legs 11,12 comprising the attachment surfaces 13, 14, which cooperate with the fixing wedges 15, 16. A bottom fixation F of the wedge profile parts 29’ is formed here by an additional wedging assembly 33 at the lower end of the wedge profile part 29', which includes a wedge block 34 guided on the wedge profile part 29', said wedge block 34 being made of a rigid plastic material such as rigid PVC or the like. For guiding and holding the wedge block 34 on the wedge profile part 29’, a guide groove 35 is provided, which is provided with an undercut and is arranged at an angle relative to the main plane H of the glass pane 3 and which is engaged by a guide web 36 formed in one piece with the wedge profile part 29’ in the manner of a sliding block. The width B of the guide web 36 is designed to be significantly smaller than the inner width I of the guide groove 35 such that a mutual transverse play Q for a relative displacement of the wedge profile part 29’ and the wedge block 34 is obtained between the guide web and the guide groove 35, 36.

As can be seen from the detail views shown in Figs. 5 and 6, the outer surface 39 of the guide web 36 and the bottom 40 of the guide groove 35 in the wedge block 34 are provided as mutual contact surfaces with an asymmetrical microserration 41,42 with alternating flat and steep tooth flanks. This causes the guide web 36 and the wedge block 34 to be locked relative to one another counter to the opening direction of the wedging in the clamped state shown in Fig. 4, ensuring an extremely stable mounting of the glass pane 3.

In the exemplary embodiment shown, the wedge angle K of the attachment leg II amounts to 7° while that of the guide web 36 and of the wedge block 34 amounts to 8.5°.

As can be seen in particular from Fig. 5, the wedge profile part 29’ underneath the attachment surfaces 13, 14 is provided with a downwardly open engagement groove 43 extending horizontally in a assembled position, said engagement groove 43 being engageable from above by a corresponding hook-shaped tool, thus allowing the wedge profile part 29’ to be removed from the carrier profile 7’ for disassembly. A further detail improvement on the wedge block 34 is the chamfer 44 provided on the outside of its flared lower end 37, which allows the weld seam 45 between the outer lateral cheek 10 and the base 25 of the carrier profile 7’ to be bridged as shown in Fig. 4 for the left-hand wedge block 34.

The assembly of the glass pane 3 in the configuration shown in Fig. 4 shall be described as follows: First, the glass pane 3 is inserted, together with two to three spacers 38 clamped thereto, into the interior of the carrier profile 7' where only the support strips 32 are positioned on the base 25. Subsequently, a corresponding number of respective wedge profile parts 29’ are inserted from above on the inside and on the outside of the glass pane 3 along the longitudinal direction thereof, wherein the wedge block 34 is in each case moved down along the wedge profile part 29' completely such that the depth of the wedging assembly 33 is less than the dimension of the gap 26 between the glass pane 3 and the respective lateral cheek 8,10 of the carrier profile 7’. This allows the wedge profile members 29 to be inserted in a relatively loose manner until the flared lower ends 37 of the wedge blocks 34 come to rest on the base 25 of the carrier profile 7'. The wedge profile parts 29 'are then acted upon from above by light tapping with a special tool, causing the wedge profile parts 29' to move down and, accordingly, the wedging assembly 33 to be clamped transversely to the glass pane 3 by the relative displacement of the wedge profile part 29 in relation to the wedge block 34. In this manner, the bottom fixation F of the glass pane 3 is obtained.

Thereafter, the fixing wedges 15, 16 are driven farther and farther into the individual wedge profile parts 29' by light tapping the from above such that a structurally defined fixation of the glass pane 3 with good vertical alignment is achieved.

Finally, the two gaps 26 are sealed at the top by the sealing strips 28 along the entire length of the railing.

Finally, Fig. 7 shows a mounting aid, in particular for the configuration shown in Fig. 4. There, a U-shaped spacer 38 is disposed on the lower edge 4, wherein approximately two to three spacers 38 of this type are distributed along the length of the glass pane 3. These spacers ensure protection of the lower edge 4 of the glass pane 3 when being inserted into the steel carrier profile 7', and ensure at the same time that the glass pane 3 is centred between the two lateral cheeks 8, 10. This ensures that the two gaps 26 have a uniform size and, correspondingly, the wedge profile parts 29 'can be introduced into the respective gap 26 without resistance.

All fixing wedges, seals and spacers may be made of EPDM plastic material.

Another embodiment of a wedge profile part 29 "is shown in Figs. 8 to 14.

This embodiment does not consist of an aluminium alloy, but is made of a rigid plastic material, just as the corresponding wedge block 34’. The design of the upper wedge fixing assembly 9" of this wedge profile part 29" corresponds to that of the wedge profile part 29', in other words it cooperates with fixing wedges 15, 16 again for the upper clamping of the glass pane 3. To avoid repetitions, reference can therefore be made to the description of the embodiments according to Figs. 3 and 4.

The embodiment differs from the configuration of the wedge profile part 29' in the region of the bottom fixation F. In this embodiment, the wedge profile part 29" is provided, at its lateral outer edges 50 facing in the wedge direction KR, with a chamfered guide web 36’ (see Figs. 9 and 10) each engaging a corresponding dovetailed guide groove 35' at the outer edges 51 of the wedge block 34' running in the wedge direction KR. The wedge block 34 ' is thus mounted such as to be displaceable in the wedge direction KR relative to the wedge profile part 29”. Furthermore, the wedge profile part 29" is provided, in its centre relative to its width, with another guide groove 55 running in the wedge direction KR. Said guide groove 55 cooperates with a corresponding guide web 56 engaging said guide groove 55, which is provided on the side 53 of the wedge block 34' facing outwardly. The mutual guidance of wedge profile part 29” and wedge block 34' is thus further improved.

As can be seen from Figs. 9 and 12, the side 52 of the wedge profile part 29” facing inwardly in the region of the bottom fixation F and the side 53 of the wedge block 34’ facing outwardly, which serve as mutual contact surfaces in the wedging process, are again provided with interlocking teeth 41,42 to prevent the relative displacement of these two components 29", 34'.

Compared to the other embodiments, the embodiment according to Figs. 8 to 14 ensures a greater tolerance compensation in the gap between the glass pane 3 and the carrier profile 7'. Additionally, an improved clamping is obtained in the bottom region F as the mutually facing contact surfaces in the form of the sides 52, 53 are designed without cavities.
