An internal corner base 1 is secured to the internal corner part, and the locking parts 9, 11 of the joiner covers 6, 7 are fitted and locked to the fitting parts 4, 5 of the internal corner base 1, respectively, to mount two joiner covers 6, 7 with the ends of the cover pieces 8, 10 on the internal corner part side overlapped with each other or brought into elastical contact with each other. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a corner joiner device used in a corner of a building. More specifically, the present invention relates to a corner joiner device that can be easily constructed with a good appearance even when the right and left wall materials constituting the corner corner are different, and is less likely to cause a gap in the corner. is there.

  2. Description of the Related Art Conventionally, there has been known an in-corner joiner device shown in FIGS. That is, this corner-joiner device has a fitting portion protruding at the inner corner of the corner corner base and a locking portion protruding at the outer corner of the cover piece formed at a right angle to form a joiner cover. The entrance corner base is fixed to the portion, and the engaging portion of the joiner cover is fitted and locked to the fitting portion of the inside corner portion of the entrance corner base.

This conventional corner-joiner device can be constructed with good appearance when the thickness of the left and right wall materials is approximately the same, but if the wall material thickness differs greatly, the joiner cover will appear to tilt. Appearance is not good. When the thickness of the wall material differs greatly, it often occurs, for example, in the case of extension or reconstruction. That is, the existing wall is left on one side and the other damaged wall is formed by metal sizing. Since the metal sizing is a thin wall material, the thicknesses of the left and right wall materials are greatly different, and the joiner cover is integrated, so that it appears to be tilted, and the appearance is deteriorated.
Japanese Patent Laid-Open No. 2002-070283 (FIGS. 4 and 5)

  The present invention solves the shortcomings of the above-mentioned conventional corner joiner device, and can be constructed with a good appearance even when the right and left wall materials constituting the corner are greatly different. It is the subject to provide.

  In order to solve the above-mentioned problems, an interior corner joiner device according to the present invention forms an interior corner base by projecting a fitting portion on each inner surface of a right-angle piece of a mold material formed substantially at a right angle, A locker is projected on the back side and a joiner cover is formed with the cover piece being a bendable piece. The locker base is fixed to the locker corner, and the locker of each locker cover is locked to each fitting part of the locker base. Each part is fitted and locked, and two joiner covers are attached by overlapping the cover end portions on the corner side.

  In another corner inserter device according to the present invention, a fitting portion is formed on each of the inner surfaces of the right-angle pieces of the mold material formed at a substantially right angle to form an entrance corner base, and is engaged with the back side of the cover piece. A joiner cover is formed with a stopper part protruding and a cover piece that can be bent, and a fitting base is fixed to the fitting corner, and a locking part of each joiner cover is fitted to each fitting part of the fitting corner base. The two joiner covers are fitted and locked, and the cover piece end portions on the corner side are elastically attached to each other.

  According to a first aspect of the present invention, there is provided a corner inserter device in which the engagement portion of each joiner cover is fitted and locked to the fitting portion of each inner surface of the right angle piece of the corner base, and the cover piece of the joiner cover is a bendable piece. In addition, since the cover piece ends on the corner side are elastically contacted with each other, even if the thickness of the left and right wall materials is different, the cover piece can cope with them, and the two joiner covers are not integral but separate. The two joiner covers are elastically in contact with each other at the cover corners on the inner corner side, so that there is little possibility that a gap will occur.

  In addition, the inner corner joiner device according to claim 2 is capable of bending the cover piece of the joiner cover by fitting and locking the engaging portions of the respective joiner covers to the engaging portions of the inner surfaces of the right angle pieces of the inner corner base. Since the cover ends of the inner corners are overlapped with each other, the cover pieces can be used even if the thickness of the left and right wall materials is different. The two joiner covers are not integrated but separate. For this reason, it does not affect the other, does not have an inclined appearance, and the two joiner covers are overlapped with each other at the cover corners on the corner side, so that there is little risk of gaps.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view showing an in-corner joiner device according to an embodiment of the present invention, FIG. 2 is a cross-sectional explanatory view showing a construction state of the embodiment shown in FIG. 1, and FIG. 3 is a diagram showing a different embodiment of the present invention. It is a cross-sectional explanatory drawing which shows a construction state.

  1 and 2, reference numeral 1 denotes a corner base, which is formed by forming fitting portions 4 and 5 on inner surfaces of right-angle pieces 2 and 3 of a mold material formed substantially at right angles. This mold material is formed of, for example, aluminum or hard synthetic resin. Reference numerals 6 and 7 each denote a joiner cover. The joiner cover 6 is formed by protruding a locking portion 9 on the back side of the cover piece 8. The joiner cover 7 is formed by protruding a locking portion 11 on the back side of the cover piece 10. The joiner covers 6 and 7 are formed by bending a steel plate, for example, and the locking portions 9 and 11 are formed by locking pieces that can be expanded by elasticity.

  The shapes of the engaging portions 4 and 5 of the corner base 1 and the engaging portions 9 and 11 of the joiner covers 6 and 7 are not limited to those shown in FIGS. 1 and 2, but may be other structures. Of course. The cover pieces 8, 10 of the joiner covers 6, 7 are formed of bendable pieces. The bendable piece is a piece that can be freely bent with a simple tool at the construction site, for example, when it is formed of a thin steel plate.

  In order to construct this entrance corner joiner device, as shown in FIG. 2, the entrance corner base 1 is fixed to the entrance corner portion, and the end portions of the wall materials 12 and 13 are placed on the entrance corner base 1 from the left and right. Next, the locking portion 9 of the joiner cover 6 is fitted and locked to the fitting portion 4 of the corner base 1, and the locking portion 11 of the joiner cover 7 is fitted to the fitting portion 5 of the corner corner base 1. Stop. In the state where the joiner covers 6 and 7 are fitted and locked, the end portions of the cover corners 8 and 10 are in close contact with each other in an elastic contact state, so that the displacement is elastically absorbed and a gap is less likely to occur. It is.

  Further, when the wall material 12 is thin and the wall material 13 is thin, the cover piece 10 is formed of a bendable piece so that it can be easily bent along the wall material 13. It is something that can be done. In this case, since the joiner covers 6 and 7 are separate, even if one of them is bent, it does not affect the other, and it does not affect the end portion on the side of the entrance corner, and the appearance is good. is there.

  3 shows a state in which the cover piece 16 of the joiner cover 14 and the cover piece 17 of the joiner cover 15 are overlapped at the end portion on the corner side. Since it overlaps at the corners of the cover pieces 16 and 17, even if a positional shift occurs between the joiner covers 14 and 15, it is absorbed by the overlapped portion, and there is little possibility of forming a gap.
