If necessary, the connecting portion 12 can be formed so as to be forcibly inserted into the end portions of the members 2, 3, 4, and the connecting form is not particularly limited to the illustrated example. Absent.

Further, the female coupling portion 13 itself is concave and has a substantially C-shaped cross section so as to share a part with the inner bottom wall portion of the groove-shaped coupling portion 12, as shown in FIG. 4 (A). like,
The joint port 15 of this is opened at about 90 °, and is substantially open to the other member 2, 3, 4 side to be joined to the position of the connecting center line C _{1 with} the members 2, 3, 4. It is tilted at 45 °. In addition, the opening width of the coupling port 15 is not larger than the maximum width of the male method in the male coupling section 18 fitted in the female coupling section 13 or the maximum width of the inner method in the coupling inner peripheral surface 14. It is set. The female connecting portion 13 itself is the male connecting portion 1 of the male member 16 described later.
Since it suffices to make a male and female connection with 8, it is sufficient if the inner peripheral surface 14 of the connection is curved in a substantially circular shape, and the outer shape is particularly limited as long as an obtuse angle is secured. is not.

On the other hand, the male member 16 itself is composed of the respective members 2,

With respect to the position, the coupling angle with the other members 2, 3, 4 to be coupled is deviated to the obtuse side.

The connecting portion 17 is formed in substantially the same structure as the connecting portion 12 of the female member 11, and its detailed description is omitted.

The male connecting portion 18 itself is convex, and is formed in a substantially circular shape in section through the constricted portion at the tip of the connecting arm portion 21, and the connecting outer peripheral surface 19 of the connecting inner peripheral surface 14 fits neatly. The curvature is preferably a little smaller than the curvature of the coupling inner peripheral surface 14 so that they come into contact with each other and at the same time a node coupling state in which they can freely swing in the female coupling portion 13 is obtained.

As shown in FIG. 4B, the connecting arm portion 21 itself is connected to the connecting center line C ₂ with the members 2, 3 and 4 in the connecting portion 17, and the other members 2 and 3 to be connected. , 4
Of the groove-shaped connecting portion 17 which is tilted toward the side by about 45 ° and which is opposite to the center position O ₂ side of the displaced male coupling portion 18 and protrudes outward from the outside of the inner bottom wall portion.

Coupling port 15 at 13
Both side portions are tightly engaged and supported on both sides of the constricted portion to allow free swinging between them (see FIG. 3).

In the drawing, the coupling between the female member 11 and the male member 16 is set such that the swing range thereof is 90 ° at the minimum and 150 ° at the maximum as shown in FIG. This is because the coupling angles of the hood member 2 and the hood member 2 of the constituent canopy device 1, the hood member 2 and the frame member 3, and the hood member 2 and the top plate member 4 are substantially within this range.
Then, when the female member 11 and the male member 16 are joined at an angle of approximately 90 ° when viewed from the side, the inner end edge of the joining port 15 abuts the inner part of the inner recess in the constricted portion, and In the case of coupling at an angle of approximately 150 ° when viewed from the side, the outer edge of the coupling port 15 comes into contact with the inner part of the outer recess of the constricted portion and stops at each position.

The inner part of the inner recess of the constricted part is located on L ₂ , and this is orthogonal to the connection center line C ₁ of the connection part 12 and passes through the center position O ₁ of the connection inner peripheral surface 14 and is the minimum inclined straight line L. The inner edge of the coupling port 15 is located on the upper part of the structure ₁ . Furthermore,
When coupled at the maximum swing angle when viewed from the side, the coupling is performed on the maximum inclined straight line M ₁ that is parallel to the coupling center line C ₁ of the coupling portion 12 and passes through the center position O ₁ of the coupling inner peripheral surface 14. The outer edge of the mouth 15 is located and it passes through the central position O ₂ of the coupling outer peripheral surface 19 and has a maximum swing angle of the coupling part 17 with respect to the coupling center line C _{2 of} , for example, approximately 150 °. The inner part of the outer recess of the constricted part is located on the maximum inclined straight line M ₂ inclined at an angle.

Of course, when the swing range is expanded or contracted, the opening width of the joint port 15, the thickness width of the constricted portion, and the connection center lines C _1, C of the connection portion 12 or the connection portion 17 are obtained. _This can be dealt with by selecting the eccentric positions of the central positions O ₁ and O _{2 in} the female coupling portion 13 or the male coupling portion 18 with respect to 2, and setting the inclination angle of the coupling port 15 or the coupling arm portion 21.
