However, the above-mentioned conventional joint material is intended only to connect the rods to form a frame. For example, other articles other than the rods are attached to the joint. There is no idea that the joint members are connected to each other to further develop a framework or the like.

[0004] Therefore, the present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a joint member of this kind with a new function so as to expand the use thereof. .

[0005]

In other words, the present invention for solving the above-mentioned problem is that a plurality of supporting portions 3 capable of fitting the rod-shaped body 6 to the joint material main body 2 have their axes intersecting each other. The joint member 1 is provided with a hole 5 into which the connecting pin 11 is inserted so that the joint members 1 can be connected to each other.

Therefore, in the joint material having the above-mentioned specific matters, a solid or hollow rod-like body is fitted to the support portion 3 to form a frame or the like. In order to further expand the frame or the like, the joint material 1 may be connected by inserting the connecting pin 11 into the hole 5 of each joint material main body 2.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a joint material according to the present invention will be described below with reference to the drawings.

(First Embodiment) In FIG. 1, reference numeral 1 denotes a joint member made of a synthetic resin. The joint member 1 has a structure in which three support portions 3 are protruded from a side surface of a joint material main body 2. The axes 3 intersect with each other at an angle of 90 °.
The outer peripheral edge of the tip of the support portion 3 is chamfered.

Reference numeral 4 denotes a through hole formed in each support portion 3 in the axial direction. Reference numeral 5 denotes a hole formed so as to coincide with the axis of the support portion 3 of the joint material main body 2. In this embodiment, the hole 5 has a shape in which a corner portion is notched, and communicates with the through hole 4 of each support portion 3. doing.

In this embodiment, the joint member 1 is formed by fitting a pipe as a rod 6 to its support portion 3 as shown in FIG.
Is formed, and a planter 9 or the like is mounted in the space 8 or a shelf is used.

When it is desired to connect the joint members 1 to each other, a connecting pin 11 having a leg 10 which can be fitted into the through hole 4 through the hole 5 of the joint member 1 is used.

FIG. 3 shows an example of the shape of the connecting pin 11, and FIG. 3 shows an example of the connecting pin 11. The connecting pin 11 is formed in a U-shape and has two legs 10. (B) has a bent rod 13 fixed to the side of a straight rod 12 and has three legs 10,
The connecting pin 11 shown in (c) is obtained by adding one bending rod 13 to this.
(D) has three straight rods 12 connected by a connecting rod 14, and one of the connecting rods 14 has a bent rod 13
And seven legs 10 are provided.

Although not shown, the connecting pin 11 may be formed by only a straight bar 12 or may be formed in a front H-shape to have four legs 10.

Then, these various connecting pins 11 are selected according to the shape of the framework 7 to be formed, and for example, as shown in FIG.
Then, the joint members 1 may be connected to each other by being inserted into the desired through holes 4 of the support portion 3.

As a result, a new framework 7 can be developed, and the stability of the entire framework 7 can be improved by connecting the respective frameworks 7.

Further, the joint material 1 is connected via a connecting pin 11.
Since it is possible to arbitrarily change the mutual connection angle of the frames, there is also an advantage that the framework 7 having various shapes can be formed.

Further, the leg 10 of the connecting pin 11 does not necessarily need to be used for connecting the joint material 1, and the other member may be connected to the frame 7 by fitting it into a hole of another member. It is possible.

The shape of the connecting pin 11 is not limited to the above embodiment, and the number of the legs 10 may be further increased,
It is also possible to change the angle and the distance between the legs 10.

(Second Embodiment) In the first embodiment,
The connecting pins 11 are inserted into the holes 5 of the joint material 1 to connect the joint materials 1 to each other. The pins 15 protruding from the floor surface 14 or the wall surface are inserted into the holes 5 as shown in FIG. It is also possible to use. In this way, the framework 7 is
There is an advantage that it can be firmly fixed to 14 mag.

(Third Embodiment) Also, as shown in FIG. 4 (b), by inserting a tube 16, an electric wire 17 and the like from the hole 5 of the joint material 1 and inserting them into the rod-shaped body 6, piping and wiring can be achieved. Can be performed without exposing the tube to the outside. For example, a hole (not shown) is formed in the peripheral surface of
Water can be supplied from 16 to the planter 9 or lighting equipment can be connected to electric wires to provide electrical decoration.

(Fourth Embodiment) Further, when a long pin 15 formed in a desired shape as shown in FIG. 5 is inserted into the hole 5 of the joint material 1 and attached, for example, the frame 7 having the pin 15 as a mounting base is provided. Can be formed, and by using the pins 15 so that they can be hung on a veranda, other members, or the like, the frame 7 or the like can be hung at a desired position.

As described above, the usage of the joint material 1 according to the present embodiment is very useful over an extremely wide range.

In the above embodiment, the rod 6 is formed in a hollow shape. However, when it is not necessary to insert the tube 16 or the like, a solid rod 6 may be used. The communication between the through hole 4 and the hole 5 is not required.

The through hole 4 of the support 3 may be omitted, but in this case, the connecting pin 11 is inserted into the hole 5 of the joint material main body 2.
The size may be set so that the pin 15 or the like can be fitted.

Further, the number of the support portions 3 protruding from the joint material main body 2 may be plural, and the crossing angle of the axis is not limited to the one described in the above embodiment. Can be arbitrarily changed according to the shape of the device.

The hole 5 formed in the joint material main body 2 does not necessarily need to coincide with the axis of the support 3 as in the above embodiment.

In addition, the material and the like of the joint member 1 are not limited to the above embodiment.

[0028]

Since the rod-shaped joint material according to the present invention has the above-mentioned specific features, it has a function which cannot be performed by a conventional joint material only for the purpose of simply connecting the rod-shaped material, namely, a joint which cannot be performed. Connecting materials, attaching pins,
A new function such as attachment of a tube or an electric wire is provided, and a particularly remarkable effect that the use mode can be greatly expanded is obtained.

Further, the joint material according to the present invention has a practical effect that it can be easily and inexpensively manufactured because the entire specified items are very simple.
