Description

[Detailed description of the invention] This invention fixes the T-shaped joint of rattan with screws*
Regarding the product.

Rattan is a natural product of the long-stemmed palm tree that grows naturally in swampy areas and jungles.

It is produced in Indonesia, the Philippines, Taiwan, etc.

In its wild state, the stem is covered with many leaves. After felling, remove the leaves and leave only the stems. The rattan wood, which is reduced to just the stem, is long, almost straight, and cylindrical.

Thick rattan materials are called Daimin, and thin ones are called Yomin.
(yomin), medium thickness (chiyumin)
It is called.

Rattan is used as a material for furniture and the like because it is lightweight, has a gentle texture, and is warm to the touch and has a soft aesthetic appearance.

Rattan includes table 1, chairs, mirror frame, screen (freshly attached), side table, bookshelf, sitting chair, reclining body, chest of drawers,
Widely used as furniture, such as dressers, beds, and umbrella stands.

Since rattan is a natural material, it cannot be produced mechanically like furniture made from metal or plastic. Almost everything is manufactured by hand.

The reason why it is not possible to automate the process of manufacturing rattan products is because the diameter of the rattan is not constant. Even with the first piece of material, the diameter is different between the wood and the end. This means that it is difficult to obtain identical materials. An expert must look at the material and use it to take advantage of its characteristics.

Furthermore, rattan can be bent into various shapes, but bending is difficult.

To bend the F1 fish, the worker uses both hands to bend the fish while exposing it to steam or flames. IM using this as a model
Put it in a dry bag. After a few days, it will be demolded, but after demolding,
The restoring force works, the curvature decreases, and the IP (~ta shape!) balances out.The return must be taken into account in advance, and the shape must be made by bending.

A cicada is a plant that has many ducts lined up in parallel in the longitudinal direction. Therefore, gas, water, etc. can be passed from one end to the other. Therefore, it is very easy to bend.

Unlike wood, it does not have a dense structure, so it cannot be fastened with nails or screws. Even if you drive a nail into it in the longitudinal direction, it will come right out. The sound of driving a nail perpendicular to the longitudinal direction,
Although a slight retaining force can be obtained, it is extremely weak.

Rattan products include a T-shaped joint where the rattan material is perpendicular to the T-shape. A nail is used to release it here and temporarily fasten it, or it is sometimes fixed with a Stella pull. Adhesive mesh may also be used. However, the desired strength f3 cannot be obtained by nailing. Furthermore, the joint must be firmly fixed by wrapping the pongee leather many times.

fII is just a composite of many tubes, and if a large local force is applied, the tube structure will break. For this reason, it is not possible to make a strong connection using a member such as a nail, which exerts force only in a narrow space.

Wrapping the raw hide around the joint is done by hand. It is a time-consuming and patient task.

When considering the shape of rattan products, mechanical considerations must be taken into consideration. A rattan T-shaped joint is not strong enough even if it is temporarily fixed with nails or adhesive and then wrapped with raw leather. The joints where force is applied should always form a triangle. To make the legs of the chair, at each joint a triangle is formed; sea urchins and rattan must be bent.

As described above, the manufacture of rattan products is mostly manual work and requires a lot of skill.

There is strong demand for high-quality rattan products. However, there are only a few skilled people who can make rattan products, so the supply is not keeping up.

) There are only a few countries, such as Taiwan, Japan, and the Philippines, that can produce male products.

[1 Wood Production 8 produces high-quality products mainly by hand.

In Taiwan, there are large factories that produce on a large scale. However, even in these factories, the products are basically handmade by craftsmen. The production line is not automated.

Productivity is low.

In addition to production, rattan products also have bottlenecks in distribution.

As already mentioned, since rattan products are produced manually by skilled workers, the final product must be packaged and shipped. It cannot be assembled by consumers or retailers. Many rattan products are light but bulky, so if they are packaged and transported, only a small amount can be transported at one time even using a large truck.

Transportation costs are extremely high.

Rattan products produced in the Philippines are inexpensive, but when they are loaded on a ship and transported to Japan, the shipping costs are high. Taiwanese products have an advantage over Philippine products in this respect.

Rattan products are also popular in European countries. It will be possible to export from Taiwan and the Philippines to European countries, but because the distance is long, the transportation costs will be significant.

Similar problems exist in Ichiboku. Since large numbers of rattan products cannot be transported efficiently by truck, it is disadvantageous to send them to remote locations. Therefore, the sales channels for rattan products are limited to those near the production area.

In this way, the 11 products had unique difficulties in terms of distribution.

The purpose of the present invention is to solve these difficulties in the production and distribution of rattan products.

Steel furniture and equipment are cheap and easy to transport, in part because they are easy to assemble. This is because it can be secured with screws.

Steel furniture and the like are often transported as parts and assembled using screws and nuts at retailers or consumers. In this way, you can save 1, ζ cost).

Assembling Nando, bolt, etc.: Since the hair groove is easy, assembly is also easy.

As mentioned above, the second rattan 1° screw IJ will not turn.

This is because if a huge force is applied to the rattan inside No. 11, the structure of the rattan will break and it will sway. However, it has never been used for rattan joints that require local fastening.

1 ~ Screw stopper groove! Without f'r and 17, transportation costs cannot be reduced.

The present invention meets these demands.

The present company is engaged in the production of rattan; 19 products among the dozens. He is familiar with the properties of bamboo blinds and how to process them.

In order to be able to connect them with a metal screw, which is a flexible natural material, it should be possible to use a strong force.

For example, impregnating a cleaning conduit with adhesive will make the rattan stiff.

However, this is ηi[shi2i]. Rattan conduits are capillaries. It takes time for the highly viscous adhesive to penetrate into the conduit. For example, let's say you have a rattan attached to a vat of glue. I don't know if the adhesive will seep in over time. However, the adhesive must not harden during this time. On the other hand, once it enters the conduit, it must solidify.

It seems that such adhesives do not exist at the moment.
I think so.

Therefore, the present inventor embedded an iron plate into a 11% rattan house, made the iron plate bear concentrated stress, and installed a T-shaped joint with screws.
I came up with the idea of creating a number.

Hereinafter, the configuration, operation, and effects of the present invention will be explained with reference to drawings showing examples.

FIG. 1 is a sectional view of a composite rattan material A used in the present invention. FIG. 2 is a sectional view taken at fT-21 in FIG. 1.

The rattan 1 (rattan) is large enough to fit into a category 6 wicker, and is preferably about 3 (1 or more) in diameter.

An iron plate 2 is embedded in the middle of the container in the longitudinal direction.

After inserting the iron plate 2, push in the rattan core 3 to cover the iron A sheet 2.

To do this, cut the rattan 1 and the iron plate 2 to the desired length, and then insert the vertical grooves 4 into the rattan 1.

1 sword #l1i41' Well, it can be easily cut out using a woodworking machine.

7. A disc-shaped saw blade is attached to the main shaft of the C11 rotation, and the blade is rotated at high speed.It is often used for wood. Align the ton iA with the blade and rotate it.If you send forest material from the island to this point, you can cut a groove 4 of a certain depth.

Once the cut 1tJI 4 is completed, push the iron plate 2f here.

This f'L is done by hitting the iron plate 2 with a hammer, a piece of wood, etc. Finally, the rattan core 3 cut into the desired size is hammered in with a hammer or the like. In this way, the reinforced rattan material A shown in FIGS. 1 and 2 is produced.

Next, cut through the rattan 1 and iron plate 2 at appropriate positions, and use a drill to drill screw holes 5.

FIG. 3 (r!) is a partial sectional view showing the entire structure of the T-shaped joint that connects the reinforced rattan material A made in this way and the iron pipe.

In this example, the diameter of the straight pipe section 6 of the iron pipe is enlarged to form an enlarged diameter end section 7 suitable for rattan material A.

A circular connecting nut 8 is welded near the end of the iron pipe. A female screw hole 9 is bored in the center of the connecting nut 8.

Place the enlarged diameter end 7 of the iron pipe at the position corresponding to the screw hole 5 of the reinforced rattan material A, and insert the set screw 1° into the screw hole 5 of the 411 strong rattan material A. The tip of the set screw 10 is screwed into the female screw hole 9 of the connecting nut 8. Tighten the set screw 10 by turning it with a screwdriver (not shown).

Since there is an iron plate 2 in the force 1A, the set screw can receive a force of 1°.

In this way, the screwed T-shaped joint is not wrapped with raw leather.

In the above example, the reinforcing rattan material A was used as the connected material of the T-shaped joint, and the iron vibrator was used as the connecting material. Here, the connected material Y
This is because in a T-type joint, the connecting member

The front end of the cap nut 12 forms a female hole 13.

Connecting (-(
, and fix and tighten the connection 14' X f: to the connected material Y.

When rattan materials are connected together in this way, the original skin 14'f is bent in order to unify the aesthetic appearance and to reinforce the ends.

As the connecting material X, two rattan materials ff and M may be used.

A third such embodiment is shown in FIG. FIG. 7 is a sectional view thereof.

A shallow cut groove is cut in the rattan 1 to the connection A, and the common iron plate 2 is inserted therein.A male screw piece 11 is welded to the #CC20 end face, as in the Ar1 example.

Insert the cap nut 12 from the screw hole 5 of the connected object E'Y and screw it onto the male screw piece 11.

The raw skin 14 is wrapped around the end of the connecting material X. Male screw piece 11f
& Saka 2 is exposed at the intersection of the rattan wood 3, but since it is wrapped in the raw hide 14, it is hidden inside.

Since the present invention is characterized by the structure of the T'';j joint, it can be applied to many rattan products.

-As an example, explain the case of a chair.

FIG. 8 is a perspective view of a chair having the joint structure of the present invention. To show the skeleton, I omitted the word "Marito" that should be placed on top of this.

This chair has a vertical front connecting member 15 and a rear connecting member 16 on the left and right sides, each having an upper width of 2 thick, and 2 horizontal bars 17 and a lower horizontal bar 1.
8, it has a side frame part S having a shape in which these parts are connected back and forth.

The structure of the connection at the side frame S is similar to that of conventional rattan products.

In this example, rattan materials such as the ring 19, the spiral 20, and the spiral 21 are connected to one part of the framework of the connecting member 15.16 and the horizontal bar 17.18.
1 and will be discussed.

These elements are provided for aesthetic enhancement and reinforcement. These members together with the horizontal bars 17, 18, connecting members 15, 16, etc. form a triangle.

In this example, especially, the intersection Q of the previous connected month 15 and the lower horizontal bar 1B,
The intersection point R between the rear connecting member 16 and the horizontal bar 17 is reinforced by a force triangle.

As shown in the figure, all the joints between rattan and rattan are covered with raw skin (1-). They nailed the rattan comrades and wrapped the raw hide around them.

In this way, the left 6 side frame portion S is manufactured. The side frame portion S and the members 22 to 25 to be connected have the screwing structure described above.

That is, the front and rear connecting members 15 and 16 are composite rattan materials in which iron plates are inserted in the vertical direction.

A screw hole is drilled at an appropriate location in this, a screw is inserted, and the connecting piece 4+ is connected to the connecting piece 4+; 122-25 by screwing.

The location where this T-shaped joint is used is indicated by P in the figure.

The connected members 22 to 25 may be iron pipes or may be composite rattan materials with iron plates embedded therein.

Here, 1 uses a chair as an example, but it is not limited to this.

Other fl! It can also be applied to products. For example, Cheagle,
Screen, side table, bookshelf, sitting chair, bed,
It can also be used as an umbrella stand.

Describe the effects.

(1) Since the connecting member and the member to be connected are connected with screws, there is no need to be an expert. In the case of a chair, only the side frame portion S is assembled at a factory, and this and the material to be connected are shipped and sold as a set so that it can be assembled by a consumer or a retailer. It can be transported efficiently without being bulky. Transportation and distribution costs are reduced.

11 will be possible to expand domestic sales channels. It is convenient for importing and exporting.

(21PJ< By embedding the board, the rattan material becomes a little heavier.

However, it is not as heavy as iron pipe. On the other hand, since there is an iron plate, the rattan is reinforced. Significantly stronger against bending and buckling.

(3) The joints of rattan products had to form a triangle of force. However, the triangular structure is not necessary when it comes to rattan rods reinforced with iron plates.

The connection is significantly simplified.
