Abstract

PURPOSE: To provide corner hardware capable of easily joining a pair of members, and preventing the easy separation thereof. CONSTITUTION: This corner hardware is used to join a pair of orthogonal members 3, and has a pair of vertical pieces 8 formed on both sides of a horizontal piece 4 in such a state as faced to each other approximately at right angles and coming in contact with the internal surface of the members 3. Also, at least a pair of driving pieces 9 are formed on the external surface of the pieces 8 for being driven into the lower edges of the members 3. As a pair of the pieces 9 are driven into the lower edges of the members 3, a joint work therefor can be easily undertaken. In this case, a pair of the pieces 8 are kept in contact with the internal surface of the members 3, thereby enabling right angles to be maintained. Also, a load acting on the members 3 in an installed state works to prevent the pieces 9 from being loosened and mounting strength can be increased. Furthermore, an adjuster bolt is screwed to the tapped hole 7 of the horizontal piece 4, thereby allowing easy height adjustment.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to corner metal.

[0002]

2. Description of the Related Art Conventionally, when a pair of orthogonal members are connected at a corner of a lower part of a box of furniture or the like, they are connected by screws.

[0003]

As described above, since the connecting operation of the pair of members is performed by the screws, there is a problem that the operation is troublesome and the workability is reduced. In addition, the screw may come off due to shaking or an external force due to an earthquake or the like, and there is a danger that the object placed on the box may fall over.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a corner fitting that can be easily connected to a pair of members and that does not easily come off.

[0005]

The corner metal fitting of the present invention is a corner metal fitting for connecting a pair of orthogonal members, and faces each other on both sides of a horizontal piece having a screw hole at an angle of approximately 90 degrees. A pair of vertical pieces that contact the inner side surfaces of the pair of members are formed, and at least a pair of driving pieces that are driven into the lower end surfaces of the pair of members are formed outside the pair of vertical pieces. Is.

[0006]

According to the structure of the present invention, since the pair of driving pieces are driven into the lower end surfaces of the pair of orthogonal members, the work of connecting the pair of members can be facilitated. At this time, since the pair of vertical pieces are in contact with the inner surfaces of the pair of members, a right angle can be accurately obtained. Further, since the structure is such that the pair of driving pieces are driven into the lower end surfaces of the pair of members as described above, the load applied to the pair of members in the installed state acts to prevent the driving pieces from coming off, so that the mounting strength is increased. Further, the height can be adjusted by screwing the adjuster bolt into the screw hole of the horizontal piece.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment of the present invention; FIG. This corner fitting 1
A pair of orthogonal members 3 and 3 are connected at the corner of the lower part of the box 2 such as furniture, and the specific shape is shown in FIG.
6 to FIG. As shown in FIG. 3, the horizontal piece 4 has a trapezoidal shape, and the oblique sides on both sides thereof form a right angle. A screw hole 7 into which the adjuster bolt 6 can be screwed is provided at the center of the horizontal piece 4. As shown in FIGS. 1, 4 and 5, a pair of vertical pieces 8, 8 facing each other at an angle of approximately 90 degrees and contacting the inner surfaces of the pair of members 3, 3 are provided on both sides of the horizontal piece 4. Hanging. Further, at the lower ends of the pair of vertical pieces 8, at least a pair of driving pieces 9, 9 which are raised outward and are driven into the lower end surfaces of the pair of members 3, 3 are formed. In this case, the horizontal portion 10 extends in the horizontal direction from the lower end of the vertical piece 8 and the tip thereof is raised to form the driving piece 9. As shown in FIG. 6, the tip of the driving piece 9 has an acute angle, and
1 is formed.

Next, an operation of connecting the pair of members 3 and 3 using the corner metal member 1 configured as described above will be described. As shown in FIG. 1, in a state where a pair of vertical pieces 8, 8 are in contact with inner surfaces of a pair of members 3, 3,
By hitting 0 with a hammer or the like, the pair of driving pieces 9 and 9 are driven into the lower end surfaces of the pair of members 3 and 3 sequentially or simultaneously. At this time, the driving piece 9 does not come out because the check portion 11 is biting into the member 3. And as shown in FIG.
The adjuster bolt 6 is screwed into the screw hole 7. Similarly, the pair of members 3 and 3 are connected at all corners of the box 2.

When the furniture is installed, the box 2 is placed on the floor surface, and the furniture body and the like are placed thereon. At this time, the horizontal portion 10 abuts on the floor and is pressed by the load of the furniture, so that the driving piece 9 and the member 3 are firmly fixed. The level of the box 2 is adjusted by operating the adjuster bolt 6. According to this embodiment, since the pair of driving pieces 9 and 9 are driven into the lower end surfaces of the pair of members 3 and 3 orthogonal to each other at the corners of the lower portion of the box body 2, the work of connecting the pair of members 3 and 3 can be facilitated. . At this time, the pair of vertical pieces 8 and 8 are attached to the pair of members 3 and 3.
Since it is in contact with the inner surface of the, it is possible to accurately form a right angle. In addition, as described above, since the pair of driving pieces 9 and 9 are driven into the lower end surfaces of the pair of members 3 and 3, the box body 2
When the installation is completed, the load applied to the pair of members 3 and 3 acts to prevent the driving piece 9 from coming off, so that the mounting strength is increased. Further, the height can be adjusted by screwing the adjuster bolt 6 into the screw hole 7 of the horizontal piece 4.

The corner metal 1 may have a shape other than that shown. For example, the vertical piece 8 may be bent in a convex shape to form the horizontal piece 4 and the horizontal portion 10 on both sides of the lower end thereof. The horizontal piece 4 may be a right triangle. Further, the number and shape of the driving pieces 9 may be appropriately changed.

[0011]

According to the metal fitting for corners of the present invention, a pair of driving pieces are driven into the lower end surfaces of a pair of orthogonal members, so that the connecting operation of the pair of members can be easily performed. At this time, since the pair of vertical pieces are in contact with the inner surfaces of the pair of members, a right angle can be accurately obtained. Further, since the structure is such that the pair of driving pieces are driven into the lower end surfaces of the pair of members as described above, the load applied to the pair of members in the installed state acts to prevent the driving pieces from coming off, so that the mounting strength is increased. Therefore, it is excellent in safety because it does not come off due to shaking such as an earthquake. Further, the height can be adjusted by screwing the adjuster bolt into the screw hole of the horizontal piece.
