Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a corner member used at the corner of a building edge.

[Conventional technology]

Generally, a perimeter edge is installed to create a smooth partition between the ceiling and wall.

The ceiling parting edge 11 is used as this surrounding edge, and is installed on the ceiling base 14 close to the wall surface 13 prior to the installation of the ceiling material 12, and the ceiling material 12 is an edge facing toward the wall surface. 15 is supported on the cut edge 11 and installed.

Each figure from FIG. 6 to FIG. 11 illustrates the basic shape of a commonly used parting edge, and shows the mounting part
A long groove material (channel material) in which a ceiling material insertion groove 19 with a U-shaped cross section is formed straight between the abutting part 17 and the decorative part 18 is made by extrusion molding of plastic or aluminum or by bending a metal plate. manufactured,
Attach the mounting part 16 to the ceiling base 14 with adhesive or screws.
It is used for installing by inserting the edge 15 of the ceiling material 12 into the insertion groove 19 to support it.

In the commonly used parting edge, the thickness of the mounting part 16, abutment part 17, and decorative part 18 is made thin, around 1 mm, respectively, due to the material cost, and the edge of the decorative part 18, on which the load of the ceiling material 12 is applied, is perpendicular to the edge of the decorative part 18. A bent flange 20 is provided to protrude and be reinforced.

This flange 20 is provided protrudingly inside the ceiling material insertion groove 19 as shown in FIG.
As shown in the figure, there are cases in which the ceiling material insertion groove 19 is provided protrudingly outside the ceiling material insertion groove 19. In the latter case, unevenness due to the flange will appear on the indoor side, so the decorative part 1 from the tip of the flange 20 to the abutting part 17
8' is added, and the decorative part is formed in a double structure.

In the case of the parting edge shown in FIG. 6, since the ceiling material is supported by the protruding end of the flange, a flat gap 21 corresponding to the height of the flange 20 is created between the ceiling material and the decorative section. In the case of the parting edge shown in FIG. 7, a flat gap 21' corresponding to the height of the flange 20 is formed between the inner decorative part 18 and the outer decorative part 18'.

FIG. 8 shows a modification of the parting edge shown in FIG. 6, in which the protruding end of the flange 20 is bent at right angles inside the insertion groove 19 to form a slightly wider ceiling material receiving part 22.
is formed.

FIG. 9 shows a parting edge that is installed to form a gap 23 between the ceiling material 12 and the wall surface 13, and is placed straight from the mounting part 16 on the outside of the abutting part 17. A tongue piece 24 that follows is provided in a protruding manner.

There are various shapes of the commonly used parting edge 11 in this way, but the ceiling material insertion groove 19 is formed by the mounting part, abutment part, and decorative part, and the thickness is commensurate with the height of the flange. The common feature is that a flat gap 21 exists.

Incidentally, there is a corner part that is perpendicular to the wall surface of a building, and at such a corner part, as shown in FIG. The installation will be carried out by aligning the 25".

[Problem that the invention attempts to solve]

In order to install a parting edge along a perpendicular wall surface, it is necessary to cut the two parting edges in a 45° direction, and then attach the cut edges 25 and 25'' against each other. It is difficult to cut in the 45° direction, and also, measure the length of the corner meeting point and cut the parting edge 11 according to that length.
Even if you cut it in the 45° direction, it is difficult to make the lengths exactly the same due to the thickness of the cutter and the deflection during cutting, and even if you can cut it in the 45° direction with the same length, It is also difficult to attach the two parting edges 11 and 11'' so that the decorative parts 18 and 18'' are flush and orthogonal.

Therefore, it takes a lot of effort to cut the conventional straight, long cutting edge at a 45° angle and attach it to the corner, and in many cases, an ugly abutment gap is created, and it is difficult to use decorative materials. The gap between the levers had to be covered, and thus, with the conventional method, it was not possible to finish the corners of the parting edges neatly and beautifully.

[Purpose of the invention] The present invention provides a flat gap 2 with a thickness corresponding to the height of the flange 20 along the length direction of the decorative part 18 at the installation location of the ceiling material using the conventional parting edge 11.
Focusing on the fact that 1 exists, this gap 21
The present invention aims to solve the above-mentioned problems by utilizing the above-mentioned problem, and to provide a corner member for finishing the ceiling beautifully.

[Structure of the idea]

The parting edge corner member 1 according to the present invention will be explained with reference to the embodiments shown in each figure from FIG. 1 to FIG. 5. It is an L-shaped member forming a ceiling material insertion groove 5 with a U-shaped cross section that is bent at a right angle and continues, and the bent corner of the ceiling material insertion groove 5 that is bent at a right angle and continues. The decorative part 3 is continuous in the shape of an L-shaped insert, and fitting tongues 6 protrude from both end surfaces of the decorative part 3 in the direction in which the ceiling material insertion groove 5 continues. Bottom surface 7 and bottom surface 8 of the decorative part
Slight steps A and B are provided between the inner surface 9 of the fitting tongue and the inner surface 10 of the decorative portion.

[Effect]

The parting edge corner member 1 according to the present invention has its insertion groove 5 aligned with the insertion groove 19 of the long parting edge 11, and the fitting tongue pieces 6 at both ends of the decorative part 3 collide with the flanges of the parting edge 11. It is used by inserting it into the gap 21 between the joints and joining them together.

As a result, the two parting edges 11 and 11'' do not come into contact with each other at the corner, and the bottom surface of the corner is the bottom surface 8 of the decorative part 3 of the parting edge corner member 1 that continues flush with the shape of an L-shaped insert. The ceiling will be beautifully finished.

The parting edge 11 must be cut at right angles in the length direction at the joining point 27 with the corner member 1, but cutting the parting edge 11 at right angles in this way is not done in the conventional method. This is easier than cutting diagonally in a 45° direction, and even if a gap is created between the decorative portions 3 and 18 of the temporary corner member 1 and the parting edge 11 at the joint 27, it will be removed. It is a straight, continuous part and is less noticeable than gaps that occur at corners.

Furthermore, the tongue piece 6 fits into the gap 21, and the decorative part 18 of the parting edge and the decorative part 3 of the corner member are flush with each other, and no step appears on the bottom surface of their joint. The joints do not have an unsightly appearance.

[Effect of idea]

As described above, when the corner member 1 according to the present invention is used, the corner of the parting edge 11 can be installed beautifully and efficiently.

[Mode of implementing the idea]

In order for the corner member to be used as described above, the end face of the decorative part of the corner member must be at right angles to the length direction of the insertion groove.
As mentioned above, even if there is a slight gap between the decorative part 3 of the corner member and the decorative part 18 of the parting edge, the effects peculiar to the present invention will not be affected. It is not essential to the present invention that it be perpendicular to the insertion groove 5.

However, the bottom surface 8 and the inner surface 10 of the decorative portion 3 of the corner member 1 are the bottom surface 28 of the decorative portion 18 of the parting edge 11.
And in order to join it so that it is flush with the inner surface 29,
A step A on the bottom surface side of the decorative portion of the corner member 1 and a step B on the inner surface side of the fitting tongue piece is made to correspond to the thickness of the decorative portion 18 of the parting edge 11 and the flange 20,
In addition, the cross-sectional shape of the fitting tongue piece 6 has a gap 21 at the cut edge.
However, the commonly used parting edges 11 are standardized and there are only a few types of cross-sectional shapes, and the decorative part 3 of the corner member and the fitting The shape of the inserting tongue piece 6 is set at any time according to the shape of the commonly used parting edge.

This corner member consists of a corner member 1' for an inward corner with an insertion groove 5' bent inward as shown in FIGS. 2 and 3, and a corner member 1' for an inward corner as shown in FIGS. 4 and 5. A corner member 1'' for a protruding corner in which an insertion groove 5'' is bent outward is manufactured and used for different purposes.

The ceiling material corner member 1 according to the present invention is manufactured by casting or injection molding, but such manufacturing method does not limit the technical scope of the present invention. It can also be manufactured by forming the groove 5 in advance with the attachment part 2, the abutting part 4, and the decorative part 3, and then joining the fitting tongue piece 6 to the decorative part 3.
