DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete constitution of the present invention will be described in detail below with reference to the drawings. In FIGS. 1 to 8 showing the disassembled state and assembled state of the joint fitting, (A) is a metal such as aluminum or its alloy. A pair of bending arms made of the same material and having the same shape as each other, and an arm main body tube (11) of a constant length (L1) for receiving a tube rod material described later, and a curved arc-shaped projection to the ventral side thereof. And a flat meshing disc (12) that continuously and integrally projects from one end.

That is, the meshing disk (12) has a thickness (T) which is about half the diameter (D) of the arm body tube (11) and is eccentric to the front side of the arm body tube (11). The front surface of the meshing disk (12) forms a flat surface that is uniform with the circumferential surface of the arm body tube (11), while the rear surface of the meshing disk (12) also has a chrysanthemum (13). ) Is engraved in the form of a spur gear.

(14) is a pin receiving hole penetratingly formed in the circular center of the meshing disk (12), and (15) is the circumferential surface of the meshing disk (12) and the arm body tube (1).
1) A stop shoulder surface which is interposed at the boundary with the arcuate one end portion, and presents a flat surface orthogonal to the longitudinal center line (OO) of the arm body tube (11).

Further, (16) has a positional relationship eccentric to the front side of the arm body tube (11), like the meshing disk (12), and is continuously and integrally projected from the abdominal surface of the arm body tube (11). It is a brace, and the ropes described later can be locked and used here. Reference numeral (17) is a receiving flange that is formed so as to project inside the hollow of the arm body pipe (11), and receives a pipe rod material, which will be described later, inserted into the hollow inside.

The pair of bending arms (A) constructed as described above are held in a state in which the chrysanthemums (13) of the meshing discs (12) mesh with each other as a front-rear positional relationship of one of the bending arms (A) facing the back. By leaning, one assembly fulcrum pin (P) is passed through the pair of matched pin receiving holes (14), so that it is pivotally connected as a joint fitting.

In this case, the assembly fulcrum pin (P) is a fastening body composed of a screw tube (18) having a constant length (L2) and a fixing nut (19) screwed to the screw tube (18). 1
8) A stopper flange (20) that engages with the flat surface of the meshing disk (12) is also projected outward from the middle portion of 8).

Therefore, by tightening the fixing nut (19) with respect to the screw tube (18) of the assembly fulcrum pin (P), the above-mentioned meshing state of the birefringent arms (A) can be fixed and maintained, while fixing the same. By loosening the nut (19), the meshing state of the birefringent arms (A) is released, and the arm body tube (1) is rotated around the fulcrum of the screw tube (18).
1) The crossing angle (θ) of each other can be adjusted to large or small. It is also possible to disassemble the birefringent arm (A) by removing the fixing nut (19) from the screw tube (18) and pulling out the screw tube (18).

Reference numeral (21) is a display scale of the crossing angle (θ), and the meshing disc (1) on one of the bending arms (A).
It is engraved on the flat surface of 2). (22) is an index arrow corresponding to the display scale (21), and is provided on the circumferential surface of the arm body tube (11) in the other bending arm (A).

In this case, if the above-mentioned restraining shoulder surfaces (15) of the birefringent arms (A) are butted against each other, the arm body tubes (11) will be aligned in a straight line with the intersection angle (θ) being 180 degrees. Becomes Further, the state in which the arm body tubes (11) of the birefringent arms (A) are arranged in parallel is the crossing angle (θ) of zero degree, and in this state, there is no possibility that the braces (16) will interfere with each other. . That is, the intersection angle (θ) is set as a constant range from 0 degree to 180 degrees.

9 to 14 exemplify the use state of the present invention applied to the assembly of a temporary tent. When using the joint fitting, the arm body tube (1) of the birefringent arm (A) is used.
A tube rod (23) which becomes a horizontal top beam of the tent is inserted and connected to 1), or a tube rod (23) which also becomes a horizontal top beam is connected to the arm main body pipe (11) in one of the bending arms (A). The arm main body in both of the bending arms (A) can be obtained by inserting and connecting another tube rod (24), which is a side pole of the tent, into the arm main body tube (11) in the other bending arm (A). The crossing angle (θ) between the pipes (11) may be adjusted and fixed appropriately.

That is, the crossing angle (θ) between adjacent ones of the lateral top beams and between the lateral top beams and the side poles, while using common joint fittings.
By freely adjusting only the above within a certain range, it is possible to perform connection work extremely lightly and efficiently.

Moreover, since the brace (16) is formed on the arm body tube (11) of the bending arm (A), the rope and the cord attached to the top seat and side seat of the tent as shown in FIG. Rope (25)
Can be locked between adjacent joint fittings in a crossed state such as an X-shape so that the seats can be stably stretched and the tent frame can be firmly fixed without distortion. And so on.

Since the assembly fulcrum pin (P) of the birefringent arm (A) is a screw tube (18) extending to a constant length (L2), it projects from the meshing disk (12) in the front-rear direction. It is possible to connect and further connect another tube rod member (26) which becomes a vertical top beam of the tent to one end or both ends of the protrusion, which is extremely convenient and versatile.

In that case, as suggested by the modified embodiment of FIG. 15 corresponding to FIG. 14, one end of a compression spring (27) curved in an arc shape is embedded and integrated into both ends of the screw tube (18). Similarly, the connecting pin (28) is also integrally projected from the free other end of the compression spring (27), while the connecting pin (28) is attached to the end of the tube rod member (26) serving as the vertical top beam. When the receiving rod (29) is formed correspondingly and the pipe rod (26) is inserted into the screw pipe (18),
The connecting pin (28) receiving the back pressure of the compression spring (27)
However, if it is determined that the receiving hole (29) is self-locking, the above connecting workability can be further enhanced.

16 and 17 show a modified embodiment of the joint fitting according to the present invention, in which the meshing disks (12) of the birefringent arms (A) are the same as each other, but the arm bodies thereof are the same. The diameter (D) of the pipe (11) is changed differently, and a pipe rod member having a different diameter can be inserted and connected to this. Since the assembly fulcrum pin (P) that pivotally connects the birefringent arms (A) can be freely inserted and removed, prepare and prepare another refracting arm (A) having a different diameter (D) of the arm body tube (11). Therefore, it can be replaced with this and assembled and used.

Then, for example, the thickness of the tube rod material (23) which becomes the horizontal top beam of the temporary tent is changed according to the installation height in the tent, or another tube rod material (24) which becomes the side pole. ) Is required to be thicker than that of the tube rod material (23) which becomes the horizontal top beam, one of the birefringent arms (A) is set as shown in FIGS. It is possible to replace the arm main body tube (11) having a diameter (D) corresponding to that with the other one, and to pivotally connect the remaining one with the assembly fulcrum pin (P). The crossing angle (θ) between the arm body pipes (11) having different diameters (D) is
It goes without saying that adjustment and fixing can be performed in the same manner as above.

In any case, in the joint fitting of the present invention, the crossing angle (θ) between the arm body tubes (11) in the birefringent arm (A) can be freely adjusted, so that FIG. 18 is not limited to the above-mentioned temporary tents, and FIG.
A simple triangular tent for cabins such as, a simple container as shown in Fig. 19, a temporary bathtub at an evacuation site, a simple warehouse,
It can be widely used for assembling the diyoungle gym etc. in the park and is versatile.

[0026]

As described above, the universal joint fitting of the present invention has a fixed length (L1) for receiving the pipe rods (23) and (24).
Of the arm main body tube (11) and a flat meshing disk (12) projecting from one end of the arm body tube (11) and comprising a pair of bending arms (A), and the meshing disks (12) of both the bending arms (A). One of them is held in a meshing state with the other side facing back, and is pivotally connected by a removable assembly fulcrum pin (P) that penetrates the center of the disk (12), and the assembly fulcrum pin (P) is connected to the screw tube (18). Fixed nut (19) screwed to this
By loosening the fixing nut (19) as a fastening body composed of and, the angle (θ) at which the arm body tubes (11) of the birefringent arms (A) intersect with each other is from 0 degree to 180 degrees.
Since the adjustment state of the crossing angle (θ) is fixedly maintained by tightening the fixing nut (19), the adjustment of the crossing angle (θ) is fixed within a fixed range up to 4 degrees. There is an effect that can improve.

That is, according to the above configuration of the present invention, the arm main body tube (11) is centered around the assembly fulcrum pin (P) that penetrates the meshing disks (12) of the birefringent arms (A).
Since the crossing angle (θ) of each other can be freely adjusted within a certain range from 0 degree to 180 degrees, one type of joint fitting can be used to make a temporary tent, a temporary bathtub, or a simple model. It can be used to assemble warehouses, containers, etc. conveniently and easily, and can respond to changes in various assembly shapes, and is extremely versatile.

The adjustment of the intersecting angle (θ) is performed by fixing the nut (1) of the assembly fulcrum pin (P) to the screw pipe (18).
The operability is excellent because it can be performed quickly and easily by the loosening operation in 9).

On the other hand, when the fixing nut (19) is tightened, the adjusting force of the crossing angle (θ) is stably and firmly maintained by the operating force and the meshing force of the meshing discs (12). Therefore, there is no possibility that the angular position is accidentally changed. As a result, it is extremely useful, especially when assembling a large temporary tent.

Further, since the assembly fulcrum pin (P) can be freely inserted and removed, the structure of claim 2 can be adopted, and according to this, it is possible to cope with the change in the thickness of the tube rods (23) (24). Then, there is an effect that the tube rods (23) and (24) having different diameters can be connected to the desired crossing angle (θ) without any trouble, and the versatility is deteriorated.

In particular, if the structure of claim 3 is adopted,
The screw tube (18) of the assembly fulcrum pin (P) is not only used for pivotally connecting both the meshing disks (12) but also orthogonal to the tube rods (23) (24) that are inserted and connected to the arm body tube (11). It can also be used more effectively for inserting and connecting another tube rod member (26).

If the structure described in claim 4 is adopted,
In the state where the crossing angle (θ) between the arm body tubes (11) is 0 degree, small-sized and flat packing, transportation, and storage can be performed, and brace (16) protruding from the arm body tube (11) is used. Then, for example, the rope (25) attached to the top sheet or the side seat of the tent can be stably locked, which is particularly useful for assembling the tent.
