Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a device for preventing deformation, crushing, and breaking of a flexible duct.

[0002]

[Prior art]

 Flexible air ducts or duct hoses that can be bent are connected between the ducts that are installed in the ceiling and air outlets for air conditioning, and between the air outlets.

[0003]

[Problems to be solved by the invention]

 However, as shown in FIGS. 7A, 7B, and 7C, the flexible duct 9 is provided between the duct 6 and the chamber box 8, the space between the duct 6 and the outlet 7, or the beam 5a. There is a problem that when the pipe is bent in a mountain-like manner over the pipe, a crushed portion 9a or breakage occurs in the middle, thereby increasing the pressure loss of the internal air and greatly reducing the amount of air flow.

[0004]

[Means for Solving the Problems]

 This invention consists of two or more flexible ducts, such as flexible ducts, duct hoses or high hoses that are plumbed for air conditioning such as heat insulation, moisture retention, and noise reduction, and flexible ducts that are connected between ducts and outlets. , So that the band is supported by the contact surface support of the support plate extending between the bands, so as to serve as an S pipe duct or an elbow as a supporter when using a flexible duct or the like, This problem was solved.

[0005]

[Embodiment of the invention]

 As shown in FIG. 1, the band 1 is formed of a semicircular band body 1a and a band-shaped band body 1b for closing an opening of the band body 1a. Reference numerals 2a and 2b denote retaining rings provided on both ends, and reference numerals 3a and 3b denote button punch-type retaining portions, and reference numeral 4 denotes a hook portion. In addition, as shown in FIG. 2A, the end of the smooth band 1b can be passed through a buckle 2c to bend and stopped in place of the button-punch-type latch, and as shown in FIG. Alternatively, the other end may be directly bent through a buckle 2c provided at one end of the band 1 and stopped.

[0006] The duct 6 can be bent freely between a duct 6 to be piped for air conditioning on the ceiling back 5 or the like and an outlet 7 mounted downward across the opening of the ceiling 5 or a chamber box 8 on the outlet 7. When connecting a flexible duct or duct hose 9 as shown in FIGS. 3 and 4, a band 1a is fitted under the flexible duct 9 or the like, and a hook 4 of a band-shaped band body 1a is hooked. 2b, the other end is fixed to the button punches 3a, 3b, and the band 1 is wound on the surface, or the hook 4 of the band 1b is hooked on the retaining ring 2b, and the other end is bent through the buckle 2c and bent. Winding, or bending one end of the band 1 directly through the buckle 2c and winding it on the contact surface, and inserting the support plate 11 between the lower retaining rings 10a, 10b to make a flexible duct or duct The lower surface of the hose 9 is brought into contact with the lower surface to support it.

When the flexible duct 9 is bent and bent so as to get over the beam 5a, the band 1 is also wound around the large bent portion of the duct 9 on the beam 5a as shown in FIG. In the same manner, the band 1 is wound around the large bent portion such as 90 degrees as shown in FIG. 4 in the same manner as shown in FIG. Can be.

[0008]

[Effect of the invention]

 As described above, according to the present invention, a flexible duct, a duct hose, a high hose or the like is wound around a band at two or more appropriate places on a pipe portion such as a flexible hose. The flexible duct is held in place to prevent crushing and deformation, and by supporting the flexible duct in contact with the support plate extending between the bands, deformation of the flexible duct and the like due to drooping is prevented, and the flexible duct is prevented. This has the effect of eliminating the pressure loss and decrease in flow rate of air.

[0009] Furthermore, by holding the band around the bent portion of the flexible duct or the like in contact with the surface and maintaining the shape, an effect is obtained that deformation, crushing, and tearing can be reliably prevented.

It is said that the flexible duct and the band can be transported more efficiently by transporting the flexible duct and the band to the piping site and winding the band around the periphery of the duct at the piping site. Produces an effect.
