JPS5921431B2 - Joint structure between vertical frame and horizontal frame - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint structure between a vertical piece and a horizontal frame in a door unit. In the joining structure of the vertical piece 1 and the horizontal frame 2 in which they are butt-joined at right angles, the horizontal piece 4 of the corner block 3 formed in an oval shape is inserted and fixed into the end of the horizontal frame 2, and the corner block 3 is Next month 5 Wedge insertion hole 6 on the outer surface
At the same time, a through hole 7 is formed at the end of the vertical piece 1.
is inserted into the end of the vertical piece 1, and with the next month 5 inserted into the vertical piece 1, the end edge of the wedge insertion hole 6 opposite to the horizontal frame 2 and the end edge of the through hole 7 opposite to the horizontal frame 2 The positional relationship between the wedge insertion hole 6 and the through hole 7 is set so that the wedge insertion hole 6 and the through hole 7 are located closer to the horizontal frame 2 than the vertical piece 1.
Drive the wedge 8 into the wedge insertion hole 6 through the through hole 7 of the wedge 8, and bring it into contact with one side edge of the wedge 8, which is opposite to the horizontal frame 2 of the wedge insertion hole 6. This relates to a joining structure of a vertical piece and a horizontal frame, characterized in that the side edge is brought into contact with the edge of the through hole 7 on the side of the horizontal frame 2.

In a door unit, in order to join the horizontal frame 2 to the vertical piece 1 at an angle of 90 degrees, the conventional method was as shown in FIGS. 1a and 1b.

That is, each of the horizontal frame 2 and the vertical piece 1 is provided with a cut-and-raised part 9,
Further, a locking recess 10 is provided in the corner block 3 bent in an abbreviated shape, and the corner block 3 is inserted into the horizontal frame 2 and the vertical piece 1, respectively, and the horizontal frame 2 and the vertical piece 1 are cut and bent 9.9. The horizontal frame 2 and the vertical piece 1 were joined at an angle of 90° by being locked in the locking recesses 10 and 10 of the corner block 3, respectively.

However, in such a conventional structure, if the cut and raised part 9 of the vertical piece 1 is not formed at an accurate position and dimension, the locking recess 1
Since the locking to the vertical piece 1 is not done accurately, the installation of the vertical piece 1 tends to be loose, and since the cut-and-raised part 9 is only locked in the locking recess 10, the cut-and-raised part 9 makes the vertical piece 1 The end face of horizontal frame 2
There is no pressing force against the end faces of the vertical piece 1 and the horizontal frame 2.
It was not possible to prevent slight gaps from occurring at the joints.

The present invention has been made in view of the above points, and there is no need for precise machining as in the case where vertical pieces are provided with cut-and-raised edges, and furthermore, the end faces of the vertical pieces and the end faces of the horizontal frame can be easily separated. It is an object of the present invention to provide a joining structure of a vertical piece and a horizontal frame that can be joined without any gaps.

The present invention will be explained in detail below with reference to Examples.

The corner block 3 is made of a synthetic resin material or the like and is bent into an L-shape. A locking recess 10 is provided on the upper surface of the horizontal piece 4 of the corner block 3, and a wedge insertion hole 6 is bored on the outer surface of the corner block 3. It is set up.

Two types of corner blocks 3 are used as shown in the conventional example shown in FIG. 1a.

The door unit is made of left and right vertical frames 1 made of aluminum shapes, etc.
The frame body is formed by joining an upper frame and a lower frame that span the horizontal frame between the upper and lower ends of vertical frame 1, and the upper and lower end surfaces of vertical frame 1 and the left and right end surfaces of horizontal frame 2 are each at an angle of 45°. It has a notch.

The vertical frame 1 has vertically elongated through holes 7 at its upper and lower ends.

Further, cut and raised portions 9 are formed at the left and right ends of the horizontal frame 2.

8 is a wedge formed by punching a steel plate, and as shown in FIG.
, 12 are provided protrudingly, and one of the hooks has a screwdriver insertion recessed step 13 not provided inside the protruding piece 12.

Therefore, when joining the vertical frame 1 to the end of the horizontal frame 2 at an angle of 90 degrees, the horizontal piece 4 of the corner block 3 is inserted into the end of the horizontal frame 2, and the locking recess 10 of the horizontal piece 4 is inserted. The corner block 3 is fixed to the end of the horizontal frame 2 by engaging the tip of the cut-and-raised part 9 of the horizontal frame 2, and then the next month 5 of the corner block 3 is fitted into the end of the vertical frame 1. .

At this time, the through hole 7 of the vertical frame 1 matches the wedge insertion hole 6 of the corner block 3, but the lower edge 6a of the wedge insertion hole 6 is slightly closer to the horizontal frame 2 of the vertical frame 1 than the lower edge 7a of the through hole 7. It is designed to shift toward the joint.

After this, the tapered piece 11 of the wedge 8 is driven into the wedge insertion hole 6 of the corner block 3 through the through hole 7 of the vertical frame 1.

In this way, the vertical frame 1 is fixed to the corner block 3 by the wedge 8, and the vertical frame 1 is joined to the horizontal frame 2 by the corner block 3.

Also, when driving the wedge 8, the lower edge of the wedge insertion hole 6 is offset from the lower edge of the through hole 7, so the tapered piece 1
1 is pushed up by the lower edge 6a of the wedge insertion hole 6 of the corner block 3, and as a result, the tapered piece 11
is pushed upward, and the end face of the vertical frame 1 is brought into close contact with the end face of the horizontal frame 2.

When removing the vertical frame 1 from the horizontal frame 2, the tip of a screwdriver is inserted into the driver lever insertion recessed step 13 of the wedge 8 and the wedge 8 is pulled out.

In addition, as shown in FIG. 6, in addition to the through hole 7, a cut-and-raised part 9 is provided in the vertical frame 1, and in addition to the wedge insertion hole 6, a locking recess 10 is provided in the next month 5 of the corner block 3, so that the corner block 3 and next month 5
In addition to the connection using the wedge 8, the locking of the cut-and-raised portion 9 into the locking recess 10 may be used in combination.

As described above, the present invention connects the vertical frame to the corner block by driving a wedge into the wedge insertion hole of the corner block through the through hole of the vertical frame, thereby joining the vertical frame and the horizontal frame. Therefore, even if the holes in the vertical frame are not formed with high accuracy, the vertical frame and the corner block can be connected by driving the wedge strongly, and the wedge can be used to connect the vertical frame and the corner block, making it possible to achieve extremely accurate machining. It can be manufactured at low cost as there is no need to apply the wedge, and when driving the wedge, the wedge can be used to press the vertical frame so that the end face of the vertical frame can be brought into close contact with the end face of the horizontal frame. It can be joined to the frame.
