Abstract

PROBLEM TO BE SOLVED: To provide a hose coupling capable of being rotated according to the counterpart position in the piping construction without deteriorating the appearance. SOLUTION: In a hose coupling 10,. an outer annular groove 20 is formed on the inner peripheral surface on the other end side of an elbow pipe 12. An inner annular groove 32 is formed on the outer peripheral surface of an inner cylindrical part 24 so as to face the outer annular groove 20, and a U-shaped engaging ring 34 is fitted into the inner annular groove 32. When the outer annular groove 20 is faced to the inner annular groove 20 by inserting the inner cylindrical part 24 into the elbow pipe 12, the engaging ring 34 is inserted into the outer annular groove 20 and the inner annular groove 32, and the elbow pipe 12 and the inner cylindrical part 24 are relatively rotatably connected to each other. Therefore, a hose 42 can be reasonably connected with it fitted to the piping form without resisting the bending tendency, and the appearance after piping can be secured.

Description of the Related Art For example, a flexible hose having a substantially L-shaped elbow pipe attached to its tip is used as a piping member for supplying water to a flush toilet unit. It is fixed to the unit body via. Such a configuration has the advantages that the hose size can be adjusted according to the piping configuration and the connection work becomes easier, as compared with the case where a piping member made entirely of metal is applied.

However, for example, when the hose 80 with the elbow pipe 82 shown in FIG. 6 or 7 is applied to the piping form to which the hose 80 with the elbow pipe 82 shown in FIG. It is necessary to change the direction of the elbow pipe 82 according to the above. Here, when the direction of the elbow pipe 82 is changed, the hose 80 is bent or twisted against the "bending" as shown by the dotted line in FIGS. 6 and 7, so that the line of the hose 80 is changed. Distortion will undermine the overall aesthetics of the unit.

The inner tube portion 24 with the hose 42 fixed is the elbow pipe 1
2 (state shown in FIG. 3). In this state, the outer diameter of the cylindrical portion 19 of the elbow pipe 12 is slightly larger than the outer diameter of the engagement ring 34 in the initial state, so that the engagement ring 34 moves the elbow pipe 12 of the inner cylinder portion 24 to the elbow pipe 12. The inner cylinder portion 24 is extremely smoothly inserted into the elbow pipe 1 without being hindered from being inserted.

Then, the engaging ring 34 comes into contact with the inclined surface of the taper portion 30 (state shown in FIG. 4). When the inner tubular portion 24 is further inserted into the elbow pipe 12 from this state, the engagement ring 34 is gradually reduced in diameter by the pressure (that is, the external force B 1 ) from the inclined surface while being smoothly guided by the inclined surface of the tapered portion 30. .

The pressure acting on 4, i.e. the radial force (i.e.
The engagement ring 34 is released from the external force B 1 ) and its elasticity restores the engagement ring 34 to the initial state. In this state, the engagement ring 34 engages with both the outer annular groove 20 and the inner annular groove 32, which prevents the inner tubular portion 24 from falling off the elbow pipe 12.

Can rotate relative to the elbow pipe 12 in a state where they are opposed to each other. For this reason, even if the hose 42 has a "curving habit", the elbow pipe 12 is rotated without turning against the "curving habit" (in other words, regardless of the direction of the "curving habit"). Can be changed freely. For this reason, piping can be installed without changing the line shape of the hose 42 without impairing the appearance.
