Description

CORNER PROFILE AND CORNER PROFILE ASSEMBLY FOR LOCKING VERTICAL PANELS IN AN INTERNAL CORNER
This invention relates to a corner profile for mounting of wall panels in an internal corner of a room. The invention relates further to a corner profile assembly for mounting of wall panels in an internal corner. The invention relates further to an internal corner profile assembly which includes the panels to be mounted and either the corner profile or the corner profile assembly. More particularly the corner profile comprises a tensioning means and the corner profile and the tensioning means are made of the same material piece. The corner profile assembly comprises an angle piece and the tensioning means comprises two parts. Even more particularly the invention relates to that the tensioning means abuts resiliently the side edge of the panel and creates a lateral force on the panel that locks the panel in position. In some embodiments the tensioning means is provided with longitudinal ridges that is forced into the side edge of the panel to assist in locking the panel in position.
Vertical panels or wall panels as described herein, are mounted side by side on a wall to make a visible sheathing or cladding. The panels may be fixed to wall studs. The panels may be joined sideways by a groove and tongue connection in their side edges. As an alternative the side edges are provided with complementary profiles forming a locking system. The panels are mounted successively to each other by connecting one panel to a mounted panel at an angel, and then rotating the panel to the same plane as the mounted panel. The connection may be made very tight and hardly visible. Such panels may be manufactured with a water repellent surface and are suitable as cladding in rooms exposed to moisture, such as bathrooms.
One disadvantage of such panels, regardless of being joined by a groove and tongue connection or with a so-called click-connection, is to make proper fitting in internal corners. There are several problems. The first problem is to cut the panels nicely along the edge that shall face the corner. This is necessary as the panels are made with a fixed width and this rarely fits with the space available for the panel closest to the corner along one wall. Therefore, it is necessary to hide the corner connection behind a corner bead. The corner bead may also hide the nails or screws that is necessary to fix the panel to the stud in the corner. Alternatively, stopper may fill the space in the corner. A corner bead or stopper will work in dry rooms but are not suitable in wet rooms. Special designed inner corner profiles are made for this purpose. Typically, such a corner profile is made of an angle piece with a first flange and a second flange at 90°. The first flange and the second flange shall face the studs. The angle piece further comprises a third flange and a fourth flange and connections between the flanges such that a first channel is formed between the first flange and the third flange and a second channel is formed between the second flange and the fourth flange. The width of the fist channel and second channel corresponds to the thickness of the panel. The angle piece may be shaped by extrusion. The angle piece may be made of plastic or metal such as aluminium.
Mounting of panels starts in one corner by cutting a first panel to an appropriate width, sliding the inner corner profile onto the edge that shall face the corner, and swinging the panel and inner corner profile into the corner. The inner corner profile is fastened to the stud along the free first or second flange. Thereby the first panel is fastened in the corner. In addition, the first panel is fastened along an upper edge along the ceiling. A sealant is filled in the channel to make the connection waterproof. Thereafter, the next panel is cut to suitable width and slid into the free channel in the corner profile, i.e., the panel is mounted on an adjoining wall. Mounting of the remaining panels must now continue in this direction, clockwise or anti-clockwise around the room.
The third flange and the fourth flange are visible after completed mounting of the panels. The visible flanges make each corner appear rounded in appearance. This is a disadvantage if a furniture with a sharp edge, i.e.90°, is to be positioned exactly within the corner.
Patent document GB913888 discloses a finisher beading for use in concealing a joint between adjacent panels or similar parts whether the parts are co-planar or at an angle to each other. The invention is useful for concealing joints between panels in the manufacture of some forms of domestic furniture.
The invention has for its object to remedy or to reduce at least one of the drawbacks of the prior art, or at least provide a useful alternative to prior art.
The object is achieved through features, which are specified in the description below and in the claims that follow.
The invention provides an elongated corner profile for fastening panels to a wall. The elongated corner profile may be first fastened to an inner corner. The panels are then cut to a suitable width and thereafter swung into the profile. The panels may be swung into the profile from both sides. The corner profile is provided with a locking means that fastens the panels to the corner profile. If the panels are cut with a nice cut, an inner corner profile assembly may be formed with a sharp internal corner. If needed a sealant or a stopper is filled into a narrow slit between the two adjacent panels in the corner.
According to the invention panels may be mounted simultaneously clockwise and anticlockwise from the same internal corner. Panels may also be mounted clockwise and anticlockwise simultaneously from two or more internal corners in the same room. This is an advantage as the invention offers more flexibility to organizing the work than known inner corner profiles. The invention also offers the advantage that several workers may work independent of each other, mounting panels in the same room on different walls.

When no pressure is applied to the tensioning means 2, the resilient turning portion 24 of the first spring 21 and the resilient turning portion 24 of the second spring 22, are not touching each other. The free end portion 25 forms an abutting face 27 on the side facing away from the junction 13. The abutting face 27 is adapted to abut the first edge 911 and the second edge 922 as seen in figures 9A-C.
In one embodiment the tensioning means 2 comprises an elongated resilient receiving body 4 that protrudes at an angle of 45° between the first flange 11 and the second flange 12, as shown in figure 3. A base 40 of the receiving body 4 is located at a junction 13 between the first flange 11 and the second flange 12. The receiving body 4 comprises an elongated first lip 41 and an elongated second lip 42. The lips 41, 42 form between them an elongated jagged slot 43. The lips 41, 42 are at their free end portion 44 provided with an elongated contact portion 46. The contact portion 46 is provided with at least one elongated ridge 45 in the longitudinal direction of the lip 41, 42. The elongated contact portion 44 faces one of the first edge 911 and the second edge 922. The ridges 45 abut the first edge 911 and second edge 922, and the ridges 45 will penetrate somewhat into the first edge 911 and second edge 922. In one embodiment shown in figure 3, the lips 41 and 42 protrude at an angle of 45° between the first flange 11 and the second flange 12. The sides of the lips 41 and 42 that are facing the slot 43 are oriented in parallel. In one embodiment shown in figures 6 and 7, the lips 41 and 42 protrude at an angle of 45° between the first flange 11 and the second flange 12. The sides of the lips 41 and 42 that are facing the slot 43 are biased towards each other such that an entrance 48 to the slot 43 forms the most narrow portion of the slot 43.
The tensioning means 2 comprises also an elongated compression rail 5. The compression rail 5 fits into the elongated slot 43. The compression rail 5 forms a first face 51 and a second face 52, a leading rail edge 50 and an opposite trailing rail edge 59. At least one of the first face 51 and the second face 52 is serrated. The serratation interacts with the jagged slot 43 such that the compression rail 5 may be displaced within the slot 43 towards the base 40, but the compression rail 5 is locked for displacement in the opposite direction. The trailing rail edge 59 is broader than the leading rail edge 50. Thereby the trailing rail edge 59 forces the first lip 41 towards the first edge 911 and the second lip 42 towards the second edge 922 when the compression rail 5 is pressed into the slot 43, as seen in figure 1C-D. A punching tool 48 which is provided with a slim punching tip 49 is used to displace the compression rail 5 into the slot 43 as seen in figure 1C. The punching tip 49 passes between the first panel 91 and the second panel 92 when the panels 91, 92 have been positioned with their back sides 919, 929 abutting the flanges 11, 12, and the edges 911, 922 abutting the ridges 45. A sealant 49 is added to fill a slit between the first panel 91 and the second panel 92 when the compression rail 5 has been pressed into the slot 43 as seen in figure 1D.
In this embodiment the corner profile assembly 100 comprises the corner profile 1, the receiving body 4 and the compression rail 5.
In an alternative embodiment the internal corner assembly 1000 comprises an elongated Y-shaped compression piece 6. The Y-shaped compression piece 6 comprises the compression rail 5.

In this embodiment the compression piece 6 is installed in the slot 43 after the first panel 91 and the second panel 92 have been positioned in the angle piece 10. The compression rail 5 of the compression piece 6 is forced into the slot 43 until the first locking wing 61 and the second locking wing 62 abut the front side 910 of the first panel 91 and the front side 920 of the second panel 92, respectively. The compression rail 5 forces the ridges 45 into the first edge 911 and the second edge 922.

In this embodiment the tensioning means 2 consists of an elongated bar 8 and screws 85. The bar 8 forms an adverse face 80, a reverse face 89, a first inclined side edge 81 and a second inclined side edge 82. The second inclined side edge 82 is oriented perpendicular to the first inclined side edge 81. The bar 8 is provided with threaded through holes 83 from the adverse face 80 to the reverse face 89. The through holes 83 are preferably spaced at regular intervals along the longitudinal axis of the bar 8. The screws 85 are adapted to the threaded through holes 83. Each screw 85 is adapted to abut a junction 13 between the first flange 11 and the second flange 12 when rotated in the through hole 83. Further turning of the screw 85 displaces the bar 8 in a direction away from the junction 13. The first inclined side edge 81 is adapted to abut the first edge 911 and the second inclined side edge 82 is adapted to abut the second edge 922.
In this embodiment the corner profile assembly 100 comprises the corner profile 1 and the elongated bar 8.
In an alternative embodiment shown in figures 9A-C, the internal corner assembly 1000 comprises an elongated corner profile 1 where the first flange 11 is provided with a first spring 21 at a distance from the junction 13 between the first flange 11 and the second flange 12. A second spring 22 protrudes from the second flange 12 at a distance from the junction 13 The first spring 21 may in one embodiment protrude resiliently from the first flange 11, and the second spring 22 may protrude resiliently from the second flange 12. The first spring 21 comprises an elongated support flange 23 which is fixed to the first flange 11 at a base 29, a resilient turning portion 24 opposite to the base 29, and a free end portion 25 directed towards the first flange 11. An edge 26 of the free end portion 25 is positioned close to the first flange 11 without abutting the first flange 11 as seen in figure 8. The second spring 22 comprises an elongated support flange 23 which is fixed to the second flange 12 at a base 29, a resilient turning portion 24 opposite to the base 29, and a free end portion 25 directed towards the second flange 12. An edge 26 of the free end portion 25 is positioned close to the second flange 12 without abutting the second flange 12. When no pressure is applied to the tensioning means 2, the resilient turning portion 24 of the first spring 21 and the resilient turning portion 24 of the second spring 22, are not touching each other. The free end portion 25 forms an abutting face 27 on the side facing away from the junction 13. The abutting face 27 is adapted to abut the first edge 911 and the second edge 922 as seen in figures 9A-C.
The tensioning means 2 is adapted to provide a lateral force on the first edge 911 and the second edge 922 when the first panel 91 is abutting the first flange 11 on the back side 919, and when the second panel 92 is abutting the second flange 12 on the back side 929, as shown in figures 9A-C. The tensioning means 2 locks the panel 91, 92 in a fixed manner to the corner profile 1.
In figures 9A-C it is shown that the second panel 92 is positioned before the first panel 91. However, the opposite order is also possible. After both panels 91, 92 are positioned and fixed by the tension means 2, the small gap between the first front side 910 and the second front side 920, as shown in figure 9C, may be filled with a sealant.
The spring 20 is resilient at the base 29. By comparing figure 9A with figure 9B, it is seen that the support flange 23 is forced towards the opposite flange (11, 12) by the panel (91, 92). The turning portion 24 is resilient, and when the turning portions 24 of the first spring 21 and the second spring 22 abut, the panel (91, 92) forces the free end portion 25 towards the support flange 23 as seen by comparing figure 9A and figure 9C. Thus, the spring 20 has two resilient portions. This secures a tight pressure of the tension means 2 towards the edges 911, 921. It also secures a tension towards the full length of the edges 911, 921 even if the corner is not perfectly vertical, or if the panels 91, 92 are not cut with straight edges 911, 921.
If the panel 91, 92 is the final panel along one wall, the neighbouring panel supports laterally the final panel 91, 92, and the final panel 91, 92 is swung into position at the corner profile 1 such that the spring 20 is tensioned properly to fix the panel 91, 92. If the panel 91, 92 is the first panel along a wall, the panel 91, 92 is first secured to the wall at the opposite elongated second edge 912, 922. Thereafter, the panel 91, 92 is swung into position at the corner profile 1 such that the spring 20 is tensioned properly to fix the panel 91, 92.
An elongated corner profile 1 for an inner corner is shown in figure 2. The corner profile 1 comprises an angle piece 10 forming a first flange 11 and a second flange 12.
