(B) Conventional technology A bellows-shaped hose used in a vacuum cleaner is known by Kimiaki Jitsumi
As shown in Japanese Patent Application Laid-Open No. 62-34515, a helical wire is usually attached to the inner surface and reinforced. When this bellows hose is connected to another pipe, it is widely used to screw the bellows hose inside the pipe. By doing so, the spiral wire provided on the inner surface of the bellows-like hose is engaged with the screw thread formed on the inner surface of the pipe, and the two are connected. However, if a configuration is adopted in which a hose is connected to the inside of the pipe, it is inevitable that the diameter of the pipe will increase.
This is an obstacle.

This problem can be solved by connecting a hose to the outside of the pipe, but in this case, as shown in FIG. 8, a valley of the bellows-like hose (3) is formed on a thread (2) formed on the outer surface of the pipe (1). Part (4) will engage. However, in the bellows-shaped hose (3), the helical wire (6) is present in the crest (5), but not in the valley (4). Does not engage with the torsion ridge (2) of the connection pipe, so that sufficient connection strength cannot be obtained.

The bellows-like hose (8) and the connection pipe (9) are always connected, and the connection structure is shown in FIGS. FIG. 4 shows a cross-sectional view of a bellows-shaped hose, in which a spiral-coated steel wire (16) coated with plastic is mounted on the inner surface of the hose. After the spiral wire (17) is fitted to the end of the outer surface of the bellows-like hose (8) as shown in FIGS. 2 and 4, the torsion formed on the outer surface of the reinforcing ring (18) is obtained. The bellows-like hose (8) is screwed into the mountain (19). This ensures that the valleys (20) of the bellows-like hose (8) reinforced by the spiral wire (17) are engaged with the torsion ridges (19) of the reinforcing ring, and the bellows-like hose (8) is Coupled to the reinforcing ring (18).

On the other hand, two annular ribs (21) and (22) are integrally formed at the outer peripheral end of the connection pipe (9), and an annular groove (23) is formed between the two ribs. The one annular rib (22)
Are formed with notches (23) at a plurality of locations thereof, and a plurality of locking pieces (25) formed by folding back at the end of the decorative ring (24) are inserted into the annular grooves (23) through the notches (23). twenty three)
After insertion, the decorative ring (24) is turned by an appropriate angle so that the locking piece (25) is completely engaged with the annular groove (23), and the decorative ring (24) is attached. An annular groove (28) is also formed between two annular ribs (26) and (27) at the end of the reinforcing ring (18), and one pair of annular ribs (27) has a plurality of pairs. A plurality of elastic pieces (28) are formed by making cuts. Spiral hose (8)
Inserting this reinforcing ring (18), which has been previously joined, into the decorative ring (24), the connecting pipe (9)
The protrusion (29) integrally formed on the inner surface of the reinforcing ring (18)
The projection (29) comes into contact with the elastic piece (28) of the annular lip when it is turned at a certain angle. The protrusion (29) gets over the elastic piece (28) and the annular groove (2
8) and the connection of the helical hose (8) and the connection pipe (9) is performed. In this embodiment, the reinforcing ring (18) and the connecting pipe (9) are separate bodies, but they may be integrated.

(G) Effect As described above, in the present invention, the reinforcing ring for attaching the connecting pipe or the reinforcing ring integral with the connecting pipe is screwed to the inner peripheral surface of the bellows-shaped hose, so that the outer diameter of the connecting portion is increased. In addition, since the spiral wire is fitted on the outer peripheral surface of the bellows-shaped hose in advance, the engagement of the reinforcing ring with the screw thread can be reliably performed and sufficient connection strength can be obtained. it can.

In addition, since the spiral wire is covered by the decorative ring, it does not impair the aesthetic appearance, and when a person uses the vacuum cleaner while holding this part in his hand, the hand is held at the end of the spiral wire. The vacuum cleaner can be used with a hose without being scratched and without the ends of the spiral wire getting caught on the sleeve end of the garment.

Further, in the present invention, since the outer peripheral side of the bellows-shaped hose is constituted by a spiral wire and a substantially cylindrical decorative ring, the actual structure described in the prior art of this specification is disclosed in Japanese Patent Publication No. 62-34515.
The structure is simpler and the assembling work is easier as compared with a structure in which a two-piece pipe body having a screw thread on the inner surface is combined with the outer peripheral side of a bellows-shaped hose as disclosed in Japanese Patent Application Laid-Open Publication No. H11-115,878.
