Description

[Detailed explanation of the idea] This invention relates to joining panel members.

Conventionally, panel members have been joined by tapping screws, bolts, or hooks using metal fittings.

However, self-tapping screws and bolt fasteners require hole drilling, so they cannot be used for panel members made of soft materials such as plastic ink, and hole drilling makes positioning difficult.

When hooking with metal fittings, it is difficult to make a tight connection, resulting in looseness, and the panel members had to be assembled in a box shape.

In joining panel members made of flat plate-like bodies, one end is slightly extended in the same direction as the end face of the panel member, and then bent, the tip thereof is formed as a protrusion having an oblique side, and the other end is attached to the end face of the panel member. An A-joint part is formed as a U-shaped hook part that is extended at a right angle and then bent at a right angle, and one end is formed as a single-shaped hook part that is slightly extended in the same direction as the end surface of the panel member and then bent, and A combination of a slightly extended portion of the L-shaped hook portion and a B joint portion formed by forming a groove portion that engages with the protrusion of the A joint portion at a portion at the same distance away from the A joint portion on the side in the perpendicular direction. The panel member is characterized in that the B-joint part is rotationally engaged with the A-joint part so that the one-shaped hook part is engaged with the U-shaped hook part and the protrusion part is fitted into the groove part. It is an object of the present invention to eliminate the above-mentioned drawbacks by providing a joint structure.

Next, this invention will be explained based on the drawings of the embodiment.1.
Reference numerals 2 denote flat panel panel members made of extruded aluminum material, iron plate, hard plastic material, etc., and filled with a filler material 3 such as hard urethane foam.

4 is the A joint of the panel member 1, and 5 is the B joint of the panel member 2.

The A-joint part 4 includes a protrusion 7 whose tip is slightly extended in the same direction as the end face 6 and then bent into a triangular shape, and a U-shaped hook part 8 which is formed by extending perpendicularly to the end face 6 and then further bending at a right angle. It consists of

The B joint part 5 includes a single-shaped hook part 10 formed by extending slightly in the same direction as the end face 9 and then bending at a right angle, and a side perpendicular to the slightly extended part 11 of the bent-shaped hook part (in this example). In this case, there is a groove 12 that engages with the protrusion 7 of the A-junction at a portion spaced apart by the same distance as the width a of the A-junction on the side perpendicular to the end face.

In this example, since the A joint part 4 and the B joint part 5 are engaged at right angles, the single-shaped hook part 10 of the B joint part 5 is set on the same surface as the end surface 9, and the groove part 12 is set at right angles to the end surface 9. However, when the A joint part 4 and the B joint part 5 are to be engaged horizontally, the groove part 12 is provided on the same surface as the end surface, and the single-shaped hook part is provided on the surface perpendicular to the end surface. establish.

Further, in this example, the protrusion 7 is formed in a triangular shape and the groove 12 is also formed in a corresponding triangular shape, but the fitting surface may be formed in a curved surface.

Further, in this example, the A joint part and the B joint part are provided at one end of separate panel members, but the A joint part and the B joint part may be provided at both ends of a single panel member.

b is the vertical length of the groove, C is the length from the tip of the protrusion to the end surface of the joint, d is the length from the inner surface of the U-shaped hook to the outer surface of the protrusion, and e is 1 This is the length of the letter-shaped hook, and f is the length from the A-junction end surface 6 to the B-junction groove-forming panel member surface when the A-junction and B-junction are in a joined state.

f is determined by s, c and e.

To assemble the panel member of this invention, the B joint part 5 is rotationally engaged with the A joint part 4, the one-shaped hook part 10 is engaged with the U-shaped hook part 8, and the protrusion part 7 is fitted into the groove part 12. By fitting, the A joint part and the B joint part are joined.

In this case, if the fitting surfaces of the protrusion 7 and the groove 12 are formed into curved surfaces, the fitting surfaces made of curved surfaces will fit into each other, making it possible to better control the movement of the panel member. The B joint portion 5 can be joined more closely.

Further, in this invention, when assembling the panel members, rattling does not occur even if they are not necessarily assembled in a box shape.

Therefore, the assembly member having the joint of this invention can be assembled not only in a box shape but also in a U-shape and an L-shape.

When assembling it into a box shape, three of the four joints will use the joints of this invention, and the other joint will be bolted.

When assembling panel members in a U-shape or an L-shape, the unjoined portions are fixed to other panel members or to a wall surface by bolts.

Since this invention has the above-described structural effect, the panel members can be closely joined.

Further, since bolts and tapping screws are not used in joining the panel members, no drilling is required, and it is possible to join soft panel members together.

Further, since no drilling is required, work efficiency is improved, and since the joint can be processed by pressing, forming, extrusion, etc., it has various effects such as reducing costs.

Therefore, this invention is suitable for intermediate joints in the assembly of panel members, joints of simple partitions in buildings,
It can be used as a joint for agricultural drying boxes, a joint for simple prefabricated sizing materials, and a joint between a lid and a lid attachment.
