Description
- The invention relates to a system for building a corner element defining a corner of a wall, an edge of a staircase, a corner edge in a floor covering or any corner element provided with adjacent boards according to claim 1 and a method of building a corner element defining a corner of a wall, an edge of a staircase, a corner edge in a floor covering or any corner element provided with adjacent boards according to
claim 12. - For example, document
CN 103485450 discloses a board mounting structure comprising a corner stud and a corner profile element. The corner profile element is fixed to the corner stud via screws. All in all, the structure ofCN 103485450 is difficult to handle. In particular, it appears to be difficult for the user to build a stable corner element by using the board mounting structure ofCN 103485450 . -
US 2009/077922 A1 also discloses a system for building a corner element. - It is an object of the present invention to propose a system which simplifies the handling of the parts thereof when building a corner element. Moreover, the overall structure should be stable and reliable. Moreover, it is an object of the present invention to propose a corresponding method for building a corner element.
- According to the invention, a system for building a corner element defining a corner of a wall, an edge of a staircase, a corner edge in a floor covering or any corner element provided with adjacent boards, comprises a corner profile element which is intended to be fixed to a corner stud, e.g. by means of an adhesive, wherein the corner profile element has two flange sections arranged in a predefined angle α with regard to each other, the system further comprising a plurality of mounting aids, in particular comprising a strip portion, and further comprising a mounting means, in particular adhesive, wherein the angle α corresponds to the angle of the corner element, wherein the corner profile element is provided with first fixing means which are adapted for fixing a cover element which is provided with corresponding second fixing means, wherein the flange sections define fixing surfaces which are adapted to be fixed, e.g. by means of an adhesive, to the outer surface of the corner stud and wherein at least one of the flange sections is provided with first openings and second openings, wherein the first openings are designed to pass the mounting aids therethrough and wherein the second openings are designed to pass the mounting means, e.g. an adhesive, therethrough.
- A core aspect of the present invention lies in the first and second openings. Thereby, the mounting procedure of the corner element is simplified, wherein a stable and reliable structure can be obtained. The first openings allow to pass a mounting aid therethrough. A mounting aid is an element which contacts (presses) the flange section to (against) a wall element so that an adhesive between the flange section and the wall element can set. Once the adhesive (or similar mounting means) has set, the mounting aid may be removed. Preferably, the mounting aid comprises a strip portion which is passed through the corresponding first opening. In essence, the first openings simplify a bonding process between the flange section (and therefore corner profile element) with an adjacent wall element. The second openings allow for a passing of adhesive (or similar mounting means) therethrough. Thereby, adhesive (or the like) can be provided on one side of the flange section and flow to the other side of the flange section so that wall element and corner stud can be attached (bonded) to the corner profile element. This also enhances and simplifies a bonding procedure. A preferred design of the first openings is a slot design. Then, a mounting aid with a strip can easily be passed in order to press the flange section against the adjacent wall element. An area covered by the second openings is preferably comparatively high (which is for example achieved by a small distance between the second openings, preferably smaller than a longest diameter of the second openings) so that a large amount of mounting means (e.g. adhesive) can pass through the flange section. Preferably, the second openings are elongated (e.g. oval or rectangular), wherein the longest diameter is preferably parallel to a longitudinal axis of the corner profile element. Thereby, a large area of the flange section can be covered with a simple structure.
- In general, the corner stud and/or corner profile element and/or cover element may be made of metal and/or plastics.
- A further aspect of the present invention is the use of the first openings for passing a mounting aid, in particular comprising a strip portion, therethrough. A further aspect of the invention is the use of the second openings for passing a mounting means, in particular an adhesive, therethrough.
- In a preferred embodiment, the corner profile element has a cover mounting section with a mounting opening facing in a direction opposite to the corner stud, wherein the cover mounting section comprises the first fixing means. The opening is preferably a groove. Alternatively or in addition, the opening may have resting projections in order to fix the cover element. In essence, such structure simplifies the fixation of the cover element.
- In an embodiment, the cover mounting section is formed as a single piece, preferably as an integral part of the corner profile element. Such a structure is very simple and reliable.
- Alternatively, the cover mounting section may comprise two or more parts, in particular an outer profile element which may be formed as an integral part of the corner profile element and an inner fastening element, which inner fastening element comprises the first fixing means adapted to engage with the second fixing means of the cover element. Such multi-part-structure allows a very flexible fixation. Moreover, it would be possible to provide the inner fastening element on the building site which simplifies the initial production costs.
- The second fixing means is in general adapted to engage with the first fixing means. For example, the second fixing means may comprise a latching protrusion (in particular a round latching protrusion) which may be arrested within the opening of the first fixing means.
- The first openings may define rectangular cut-outs, in particular slots. The rectangular cut-outs or slots may have a width of less than 3 mm, preferably less than 2 mm and/or more than 0.5 mm, preferably more than 1 mm. By such dimensions, the mounting aid (e.g. comprising a strip portion) can easily be passed (pulled) through the first opening.
- The second openings may define rectangular cut-outs, preferably with a width of less than 5 mm, further preferably less than 3 mm. A lower limit may be more than 2 mm. In general, the width of the second openings may be larger than the width of the first openings. The term "width" shall mean preferably a dimension of the cut-outs (slots) perpendicular to a longitudinal axis of the corner profile element. If the width of the second openings is rather large, a sufficient amount of adhesive can pass through the openings. If the width of the first openings is rather small, the overall structure of the corner profile element stays stable. At the same time, a strip portion can be pulled through the first openings.
- The first openings are preferably aligned along a first line. Alternatively or in addition the second openings may be aligned along a second line. Preferably the first line is at a distance from the second line. By such alignment, the overall structure of the corner profile element is very stable. On the other hand, a reliable bonding of the corner profile element with the adjacent wall element and/or the adjacent corner stud is possible.
- In an embodiment, the number of the second openings is higher than the number of the first openings. Preferably, the ratio of the number of the second openings in relation to the number of the first openings is at least 2.0, preferably at least 3.0, further preferably at least 4.0. Thereby, the numbers of openings are particularly suitable for their purpose.
- A distance between the first openings may be at least 10 cm, preferably at least 20 cm and/or not more than 40 cm, preferably not more than 30 cm. Alternatively or in addition, average distance between the second openings may be at least 1 cm, preferably at least 3 cm and/or not more than 10 cm, preferably not more than 5 cm. In essence, the distance between the first openings (each pair of first openings) is rather large. Thereby, the structure is very stable. On the other hand, the distance between the second openings is smaller so that a sufficient amount of mounting means (adhesive) can pass (flow) through the openings. In an embodiment, the length of a cross-section of the first flange section perpendicular to a longitudinal profile axis is more than the length of a cross-section of the second flange section perpendicular to the longitudinal profile axis. Alternatively or in addition, the first flange section comprises first and second openings and the second flange section is solid. The longer flange section (with first and second openings) can be used to bond the corner stud, the corner profile element and the adjacent wall element together. In such a case, the shorter flange section can be bonded to the wall element (without necessarily an additional bonding to the corner stud). All in all, the amount of material (of the corner profile element and/or any mounting aids/means) is reduced so that the costs are reduced.
- In an alternative embodiment, the length of a cross-section of the first flange section perpendicular to a longitudinal profile axis is equal to a length of a cross-section of the second flange section perpendicular to the longitudinal profile axis. Alternatively or in addition, both flange sections comprise first and second openings. In such a case, both flange sections can be securely bonded to adjacent wall elements/corner studs so that a stable overall construction can be obtained.
- In a preferred embodiment, the mounting aids comprise at least one resting means, in particular recess. By such recess, the mounting aid can be arrested within a fastening part which may be pressed against the wall element and/or cover element so that an adhesive may cure.
- The mounting aid may have a first and/or a second predetermined tearing point. The first tearing point may be far from a base portion of the mounting aid (in particular further away than half the distance from the base portion to the other end of the mounting aid). The second tearing point may be close to a base portion of the mounting aid (in particular closer than half or quarter of a distance from the base portion to the other end of the mounting aid). The first tearing point may define a predetermined force which can be applied by pulling the mounting aid until the tearing point tears. Thereby, the elements to be bonded are pressed together and the adhesive can set. The second tearing point is useful in order to remove the mounting aid after a curing of the adhesive.
- Another aspect of the present invention is a method of building a corner element defining a corner of a wall, an edge of a staircase, a corner edge in a floor covering or any corner element provided with adjacent boards, comprising the steps:
- providing a system of the kind above
- passing a mounting aid through the first openings and/or passing a mounting means, e.g. an adhesive, through the second openings.
- The mounting aids comprise preferably a resting means, wherein the mounting aids are passed through the first openings and through fastening members, locking the mounting aids, preferably wherein the fastening members are pressed against a wall element, in particular whilst the mounting aids are pulled, further preferably until a first tearing point tears so that an adhesive may set. By such method, the bonding of the corner profile element with the corresponding wall element is reliable and simple.
- The mounting aid may be pulled again until a second tearing point tears so that the mounting aid is unlocked (destroyed). In particular, the mounting aid tears into two parts wherein one part may stay within the board mounting structure (invisible) and or the other part may fall on the ground (e.g. together with the fastening part).
- The wall (or wall elements) may be a dry wall (dry wall element) in particular gypsum plasterboard. An aspect of the invention is a dry wall construction including building constructions with building boards, in particular gypsum plasterboards fastened on a substructure, wherein a system of the kind above provides a solution for the corner region. Other applications may be tiled finishes, wood linings, etc. The cover element can be used for an (impact-resistant) corner design with a simple look. It can be produced from various materials (e.g. plastics, metals etc.)
- The corner stud may be a C- or CW- profile.
- The cover mounting section may have a mounting opening facing in an oblique direction (e.g. at 45° to the adjacent wall elements of the corner). First and second fixing means can be latched detachably or non-detachably.
- Preferably, the first and second fixing means can be assembled (latched together) variably in depth. Thereby, different material thicknesses and material differences can be compensated.
- The adhesive may be for example a tile adhesive or another adhesive.
- First and/or second fixing means can be flexible in order to securely lock the first and second fixing means.
- The cover element can be constituted slip-resistance and/or fluorescent and/or illuminated and/or segmented and/or structured etc.
- Preferably, the first and second fixing means are configured to allow at least two, further preferably at least three, even further preferably at least four different fixing positions. Hence, the cover profile element can be assembled variably in depth. Different material thicknesses and material differences can thus be accommodated or compensated for.
- A fixing between the first and second fixing means can be constituted in such a way that the cover profile element is replaceable or is fixed permanently.

Figs. 1 to 6 show a method for building acorner element 10 comprising twowall elements 27, acorner stud 11, acorner profile element 12 and a cover element 20 (compareFig. 4 ). - The
corner stud 11 is preferably a C-profile element (in particular a CW-profile element; compareFig. 7 ). Thecorner profile element 12 comprisesfirst openings 17 and second openings 18 (compare alsoFig. 12 ).First openings 17 andsecond openings 18 may be (as it is shown inFigs. 12 and 13 ) aligned along a line which is parallel to the longitudinal profile axis. - According to
Fig. 1 ,corner stud 11,corner profile element 12 and thewall elements 27 are arranged in order to form acorner element 10. In the embodiment of thecorner profile element 11 ofFig. 1 , only a first flange section 13 (compare alsoFigs. 10 to 12 ) has theopenings first flange 13 to thecorner stud 11 and thewall element 27 being adjacent to thefirst flange 13, is described inFigs. 1 to 4 . Asecond flange 14 may be bonded and fixed in a suitable (e.g. conventional) method. - In
Figs. 1 to 4 , an adhesive (glue) is used in order to bondcorner stud 11,corner profile element 12 andwall element 27. Since thefirst flange section 13 comprises thesecond openings 18, the adhesive can easily pass through theflange section 13 and thereby cover (at least partially) both sides of theflange section 13 when applied on one side. In this respect, the adhesive is applied on the side of theflange section 13 facing the wall element 27 (alternatively, the adhesive may be applied on the side facing the corner stud 11). - Until the adhesive is set, it is necessary to press the parts to be bonded together. This is done by a mounting aid 21 (compare
Figs. 2 and 6 ), comprising astrip portion 28 and abase portion 29, and a fastening member 30 (fastening cap; compareFig. 5 and 3 ). After the adhesive has been applied, thestrip portion 28 of the mountingaid 21 is pulled through one of thefirst openings 17 and one ofopenings 31 within thefastening member 30. Theopenings 31 are arranged on an edge of thefastening member 30 so that they may be advantageously used for the connection of thecorner element 10. - The
fastening member 30 comprisesfurther openings opening 32 is arranged next to theopenings 31 and may be used to insert a fastening aid for bonding a profile element to a wall element in a corner region. Theopening 33 may be used for inserting a mounting aid when a profile element (anywhere in a free space) has to be mounted to a wall element. Thebase portion 29 is adjacent to thecorner stud 11. Adistal end 34 of the mountingaid 21 is arranged on a side of the wall element facing away from thecorner stud 11. - In order to press
corner stud 11,corner profile element 12 andwall element 27 together, thefastening part 30 is held against an adjacent surface of thewall element 27. At the same time, thedistal end 34 of the mounting aid is pulled. A resting means 35 (comprising small, e.g. rib-like, projections) of the mounting aid 21 (compareFig. 6 ) holds thefastening member 30 in its position so that a pressing force is achieved between the fasteningmember 30 and thebase portion 29 of the mountingaid 21. In order to provide a pulling force, a suitable element (e.g. a screwdriver) may be inserted to afirst opening 36 of the mountingaid 21. The mountingaid 21 has afirst tearing point 37 which breaks when the force of thefastening member 30 on the parts to be bonded is sufficient to bond the parts together. - Once the adhesive has set, the mounting aid is pulled again until the mounting aid tears again at a second tearing point 38 (see
Fig. 6 ). In order to provide a pulling force a suitable means (e.g. a screwdriver) can be inserted into asecond opening 39 of the mountingaid 21. The torn-off portion of thefastening aid 21 is removed from thewall element 27. Thebase portion 29 of the mountingaid 21 stays inside the corner stud 11 (falling into the corner stud 11). - The
fastening member 30 may have a box-like shape preferably with flanges 40 (compareFig. 5 ) which may be pressed against thecorresponding wall element 27. - As soon as the mounting
aid 21 has been removed,corner stud 11,corner profile element 12 and thecorresponding wall element 27 are securely bonded together. Thereafter, thecover element 20 is fixed to thecorner profile element 12 by first and second fixing means 15, 16 (compareFig. 4 ) in a mountingsection 23. The first fixing means 15 comprise aprofile element 25 defining a mountingopening 24. The second fixing means 16 comprises a (longitudinal)inner fastening part 26. Theinner fastening part 26 may have a spheric cross-section. Theinner fastening part 26 rests in two opposingindentations 41. The mountingopening 24 comprises a plurality (at least three or at least four) pairs of opposingindentations 41 so that theinner fastening part 26 may be located in different positions. Thereby, a plurality ofcover elements 20 may be used (which are different in material thickness and/or materials and/or shapes). The mountingopening 24 is in the present embodiment (different angles are possible) aligned in a 45° angle in respect of a line perpendicular to the surface of thefirst flange section 13. - The mounting
opening 24 may define a groove into which theinner fastening part 26 may be pressed (latched). The inner fastening part 26 (latching element) of thecover element 20 can be fixed either non-detachably or detachably. The combination of thecorner profile element 12 and thecover element 20 enables a fixing or pressing-on of wall elements during the assembly. - In general, the
cover element 20 may be provided with additional functions such as lighting elements, fluorescent elements etc. -
Figs. 7 and 8 show an alternative embodiment for thecover mounting section 23. Thecover element 20 is identical to thecover element 20 of the embodiment ofFigs. 1 to 4 . Thecorner stud 11 may be identical to the corner stud ofFigs. 1 to 4 . InFig. 7 , one can see that thecorner stud 11 is a C-profile (precisely, a CW-profile). - The
corner profile element 12 of the embodiment ofFigs. 7 and 8 is different to theprofile element 12 of the embodiment ofFigs. 1 to 4 . Thecorner profile element 12 ofFigs. 7 and 8 comprises anouter profile element 42 which is (preferably an integral) part of thecorner profile element 12. Within theouter profile element 42, aninner fastening part 43 is located. Theinner fastening element 43 comprises a U-section 44 which rests in theouter profile element 42. Moreover, theinner fastening element 43 comprises a Y-section 45 (different shapes are possible) with a mountingopening 24 in which thefastening part 26 is arrested. - In the embodiment of
Figs. 7 and 8 , an adaption to coverelements 20 with different properties (e.g. material thickness and/or material and/or shape) may be done by a suitable choice of aninner fastening element 43 from a set of differentinner fastening elements 43. -
Fig. 9 shows a further embodiment with the following differences in respect of the embodiment ofFigs. 7 and 8 . Instead of theinner fastening element 43 of the embodiment ofFigs. 7 and 8 , a differentinner fastening element 43 is shown. Theinner fastening element 43 ofFig. 9 may be a (flexible) material strip which may be non-detachably inserted into theouter profile element 42. Theinner fastening element 43 ofFig. 9 comprises the mountingopening 24. -
Fig. 10 shows a side view (withindicated openings 17 and 18) of thecorner profile element 12 ofFigs. 1 to 4 .Fig. 11 shows a side view (withindicated openings 17 and 18) of thecorner profile element 12 ofFigs. 7 and 8 as well asFig. 9 .Fig. 12 shows thecorner profile element 12 of the embodiment ofFigs. 7 and 8 as well asFig. 9 . -
Fig. 13 shows an alternative embodiment of thecorner profile element 12. - Instead of only one
flange section 13 withopenings Fig. 13 comprisesopenings flange sections flange sections Figs. 1 to 4 . In the embodiment ofFig. 13 , theflange sections Figs. 10 and 11 ). The embodiment of thecorner profile element 12 ofFigs. 1 to 11 have afirst flange section 13 which is longer (in a cross-section perpendicular to a longitudinal profile axis) than the second flange section 14 (compareFigs. 10 and 11 ). - In a further embodiment (not shown in the figures) the
corner profile element 12 may have the flange sections as shown inFig. 13 and aprofile element 25 as shown inFig. 10 . - In general, the
corner profile element 12 and thecorner stud 11 may be bonded (glued) together as a substructure. Such structure may be bonded to thewall elements 27 by using the mounting aids 21. In an alternative embodiment, thecorner stud 11,corner profile element 12 andcorresponding wall element 27 are bonded together in one single step. In any case, the mountingaid 21 may be removed (after a bonding and setting period). - The
inner fastening element 43 of the embodiments ofFigs. 7 and 8 as well asFig. 9 may be accommodated on the building site of the wall element or be inserted at the factory. -
