DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of joining a plurality of rod-shaped members between two plate members, for example, when attaching a knot to a stile in a paper-attached shoji lattice unit of an aluminum interior fitting.

[0002]

2. Description of the Related Art Heretofore, it has been widely practiced to assemble a fitting such as a shoji screen or a bran used for a house or the like with a metal member such as aluminum and to attach paper thereto.

In this case, as a method of joining such metal members to each other, a method of screwing is generally used. As shown in FIG. 5, for example, a shoji screen is formed by vertical stitches a, b, A method of assembling the lattice unit g by bonding the braid e to the stile c and the lower stile d with the screw f, and attaching paper to the lattice unit g is generally adopted.

[0004]

However, as shown in FIG. 5, for example, when a plurality of braids e are connected by a screw f between two vertical stiles a and b and installed, the screws are not fixed at the time of screwing. Is a rotational motion, and the rotational direction is reversed between the case where the knitting e is screwed to one vertical stile a and the case where the knitting e is screwed to the other vertical stile b. In some cases, the braid e may be twisted, and the undulation may occur on the paper sticking surface of the lattice unit g. Unless the paper pasting surfaces of each lattice are on the same plane, it is difficult to paste the paper neatly.Conventionally, when the lattice unit swells like this, each pair of mats is placed on the same plane with a hammer or pliers. At present, they are forced to work manually one by one so that the workability is poor.

SUMMARY OF THE INVENTION The present invention has been made to improve the above circumstances, and is used when a plurality of rod-like members are bridged between two plate members, such as when assembling a lattice unit of aluminum fittings such as the above-mentioned shoji and bran. It is an object of the present invention to provide a method for easily joining a plate member and a rod-shaped member without causing twisting, undulation, and the like.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for joining two ends of a plurality of rod-shaped members, each having an open end, between two opposing plate members. A fastening hole is formed at each joint of the two plate members with the rod-shaped member, and a blind rivet main body is inserted into the end opening of the rod-shaped member from these fastening holes, and the shaft of the rivet is fixed. By the pressing force of the base flange portion mainly composed of rivets and the bulging portion formed by the head protruding from the cylindrical main portion connected to this flange portion retreating into the cylindrical main portion, Provided is a method for joining members, comprising fixing a plate member and a rod-shaped member.

According to the present invention, the plate member and the rod-shaped member are pulled out (clinched) of the shaft portion of the blind rivet, so that the pressing force against the plate material by the rivet-based base flange portion and the rivet-based cylindrical main portion are formed. The rivet head is retracted, and the cylindrical main portion is buckled to form a bulging portion, which presses against the peripheral wall surface of the end opening of the rod-shaped member, thereby firmly connecting and fixing.

In this case, the pulling force of the rivet shaft is:
Acting in the axial direction of the rod-shaped member, the pressing force of the flange portion against the plate also acts on the plate material surface, and is along the axial direction of the rod-shaped member. Acting at right angles to the axial direction, rotating the rod-shaped member and exerting no twisting force, when the method of the present invention is applied to assembling a lattice unit such as a shoji screen, the lattice unit twists and undulates. Therefore, the members can be joined while keeping the paper pasting surfaces of the respective sets on the same plane.

Further, according to the method of the present invention, it is only necessary to insert the rivet main body of the blind rivet into the end opening of the rod-shaped member from the fastening hole of the plate material and to pull out (cauld) the rivet shaft portion. The connection with the rod-shaped member is performed in a so-called one-touch manner, and it is not necessary to correct twist, undulation and the like after the connection, so that workability is good and work efficiency is high.

[0010] In the present invention, the end opening of the rod-shaped member has one or more voids adjacent to the insertion part into which the rivet main body is inserted and communicating with the insertion part. Is preferred.

That is, in the case where the end opening of the rod-shaped member is merely formed with an insertion portion into which the rivet main body is inserted,
The entire peripheral wall surface of the end opening is pressed by the bulging portion,
The outer peripheral surface of the end of the rod-shaped member may also bulge. this is,
In particular, when forming a lattice unit such as a shoji screen and pasting paper, even if the paper pasting surfaces of the kumiko are on the same plane, the pasting surface will be greatly expanded, Work against you. However, as described above, by forming a gap adjacent to and communicating with the insertion portion and providing a clearance, bulging of the outer peripheral surface of the end portion of the rod-shaped member opposed to the gap is suppressed. In particular, for the above-described knitting, the swelling of the paper pasting surface is suppressed by providing a void portion on the paper pasting surface side so as to face the paper pasting surface. be able to.

In the present invention, the material of the plate and the rod-shaped member is not necessarily limited, but the present invention is effective for a metal material such as aluminum or steel.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 schematically shows a paper stitching lattice unit of an aluminum interior fitting. In FIG. 1, reference numeral 1 denotes a vertical stile (plate material); In this example, there are three sets (bar-shaped members), and the shoji paper 3 is attached to the paper attaching surface 2a of each of the sets 2.

The vertical stile 1 is formed in a plate shape, and a fastening hole 11 corresponding to an outer diameter of a rivet main body 41 of a blind rivet 4 to be described later is formed at a connecting portion with the bracket 2.
Are drilled. In addition, the above-mentioned knitting member 2 is formed in a substantially rectangular cylindrical shape, and the paper pasting surface 2a is formed to be flat.
The two opening portions 21 are formed with a circular insertion portion 22 into which the rivet main body 41 is inserted as shown in FIG.
A substantially triangular or trapezoidal fin-shaped space 23 formed on the paper pasting surface 2a side adjacent to and communicating with the paper pasting surface 2 so that one side faces the paper pasting surface 2a; Part 22
And a rectangular gap 24 formed on the side opposite to the fin-shaped gap 23 in communication with the fin-shaped gap 23. In this case, the communicating portion between the circular insertion portion 22 and the fin-shaped space portion 23 and the rectangular space portion 24 is formed to be narrower than the diameter of the insertion portion 22.

When the braid 2 is connected to the vertical stile 1, as shown in FIG. 3, the fastening holes 11 of the vertical stile 1 correspond to the openings 21 of the braid 2, and the blind The rivet main body 41 of the rivet 4 is inserted into the insertion portion 22 of the opening 21.

Here, the blind rivet 4 is composed of a rivet main body 41 in which a ring-shaped flange portion 43 is integrally protruded from a base outer peripheral edge of a cylindrical main portion 42, and a rivet inserted into the main portion 42. The base portion of the shaft portion 44 protrudes outward from the rivet main body 41, and the distal end portion protrudes outward from the distal end portion of the main portion 42. It has a slightly larger diameter head 45, and a constriction 46 is provided at the connection between the shaft 44 and the head 45.
Are formed.

Therefore, when the rivet main body 41 is inserted into the insertion portion 22 through the fastening hole 11, the inner surface of the flange portion 43 of the rivet main body 41 comes into contact with the outer surface of the stile 1 and the base side of the rivet shaft portion 44 is outward of the stile 1. It is in a state of protruding.

In this state, by pulling out (caulking) the rivet shaft portion 44 while pressing the flange portion 43 using an appropriate fastening tool, as shown in FIG. It retreats into the main part 42, acts to buckle the main part 42, the head 44 bulges the main part 42 in the radial direction, and the head 45 is the rivet shaft 4
4 The head 4 is torn off at the constriction 46 from the tip.
5 is held in the main part 42, and the rivet shaft 44 is pulled out from the rivet main body 41.

Thus, the stile 1 and the braid 2 form a bulging portion 47 formed by the flange portion 43 pressing the outer surface of the stile 1 and the head portion 42 bulging the main portion 42 in the radial direction. Presses against the inner peripheral surface of the opening 21 of the pair 2 to be firmly connected and fixed.

Thus, for the above vertical stile 1,
One end of a plurality (three in FIG. 1) of braids 2 is sequentially connected, and, although not shown in FIG. 1, arranged opposite to one vertical stile 1 as shown in FIG. The other end of the pair 2 is similarly connected to the other vertical stile. In a lattice unit as shown in FIG. 5, for example, braids are arranged and connected to the upper and lower stiles in the same manner as above in the vertical direction in the figure.

According to the above-described joining method, the joining force acts only in the length direction and the radial direction of the knitting 2 and no force for rotating or twisting the knitting 2 acts. When a plurality of braids 2 are joined to the stile 1, the surface directions of the paper pasting surfaces 2a are unlikely to be inconsistent, and they are joined while maintaining the same plane.

Further, in the above-described joining method,
The opening 21 communicates with the insertion portion 22 and has gaps 23 and 24 formed on both sides thereof. In this case, since the fin-shaped gap 23 is provided particularly on the side of the paper pasting surface 2a, the rivet is formed. The head part 45 of the shaft part 44 retreats into the main part 42 and the main part 4
When the head 2 is bulged, the pressing force exerted by the head 45 in the direction of the fin-shaped space 23 acts so as to crush the space 23, so that the space 23 cushions the paper pasting surface 2 a. The pressing force acting directly is reduced, and the paper pasting surface 2a is prevented from greatly expanding, so that the paper pasting surface 2a maintains substantially flatness.

Therefore, the shoji paper can be stuck neatly on the stuck side 2a.

In the above embodiment, the case of assembling the paper-attached sash lattice unit of the aluminum interior fittings has been described. However, the joining method according to the present invention is not limited to this, and it is not limited to this. A plurality of rod-like members having at least both ends opened, such as a cylindrical shape, can be connected to each other, and can be effectively applied to the joining of members when bridging between these plate materials. The materials of the plate materials and the rod-like members are also made of aluminum. The present invention is not limited to this, and other metals such as steel or a plastic material may be used as the case may be. Of course, the plate material and the rod member may be different materials.

Further, in the above embodiment, the knot (rod-like member)
The opening of the rivet has an insertion portion into which the rivet main portion is inserted, and two gaps, but the shape of the gap is not particularly limited. Any shape can be used as long as it can release the pressure force by the head, buffer it, and prevent the required surface from swelling, but the fin-like shape as shown This is preferable because it can be crushed. Further, the number of the gaps is not limited, and the formation of the gaps may be omitted when the outer peripheral surface of the rod-shaped member may swell over the entire circumference.

Further, other configurations may be variously changed without departing from the gist of the present invention.

[0028]

According to the present invention, two plate members and a plurality of rod members can be easily and firmly connected without twisting and undulating.
