Claims

[Scope of utility model registration request]

A duct toy with a quadrilateral cross section has round-shaped flanges 1 and 1' at the connecting edges of the upper, lower, left, and right walls, and a partial joint member 21 (described later) is attached to the lower surface of the horizontal portion of each flange 1, 1'. A partial joint member, which will be described later, is formed by forming a fitting groove 5 for a fitting edge and a joint edge 6, and protruding ridges 7 on the upper, lower, left, and right wall surfaces of the duct toy on lines close to and parallel to the connecting edge. 2
A fitting groove 8 is formed for the lower fitting edge of the duct 1, and inwardly bent portions 17 are provided at both ends separately from the duct toy.
Clip-on type covering part 18 with a square cross section having a diameter of 17'
A partial joint member 21 is formed of a raised part 19 extending downward from the tip edge of one inwardly bent part 17 and an outwardly bent edge 20 connected to the lower edge of the raised part 19. One inwardly bent portion 17 and outwardly bent edge 20 of this partial joint member 21 are used as an upper fitting edge 22 and a lower fitting edge 23, and the partial joint member 21 is attached to the outside of the intermediate portion of the flange 1. By placing the raised part 19 of the partial joint member 21 in the space between the joint edge 6 and the wall surface of the duct toy, the upper fitting edge 14 and the lower fitting edge 15 are connected to the fitting edge 14 and the lower fitting edge 15 as described above. A duct device characterized in that a partial joint member 21 is fixed to an intermediate portion of a flange 1 by fitting into grooves 5 and 8.
