Abstract

PURPOSE:To obtain the bubble bath extension hose which is simple in its constitution, can be joined firmly and is excellent in its durability by providing a bead part on the outside peripheral surface of a cylindrical soft connecting part and fitting a crest of a flexible hose thereto, and also, providing an elastic body on the inside surface of the bead part, and joining the soft connecting part and the flexible hose. CONSTITUTION:By forming an annular groove 8a for fitting an end part of a flexible hose 6a to one end part of a cylindrical soft connecting part 8 formed by a rubber material, and extending an inside collar 8c for forming the groove concerned 8a, an annular bead part 9 is formed on the outside peripheral surface. In the flexible hose 6a, annular crest parts 10 and through parts 10a are formed continuously so as to run along a shape of this bead part 9. In such a state, an inner collar 9 having the bead part 9 to which the hose 6a is fitted is pushed by a plate spring 11 provided on this inside and joined surely to the hose 6a. Accordingly, since the soft connecting part 8 can be attached and detached simply and easily to and from a jet nozzle part for generating bubbles, the assembly can be executed extremely simply and surely, and the bubble bath extension hose whose yield is high and whose durability is excellent even at the time of actual use is obtained.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention provides a bubble bath extension hose that can be attached to a fixed jet nozzle part that generates bubbles in bath water, and can freely apply bubble jets to desired parts of the body. It is related to.

BACKGROUND OF THE INVENTION In order to make bathing, an essential part of daily life, more comfortable, temperature baths that generate air bubbles in the bath water are attracting attention, as they have a pine surge function that relieves the fatigue of the day, a heating function, and a cleaning function. In conventional bubble baths, a jet nozzle fixed to the bathtub wall is the mainstream, and most bubble water heaters in particular have one or two holes (two holes), making it possible to bathe the entire body with bubbles. was difficult. Therefore, in order to freely apply the bubble jet to the desired part of the body,
The idea of using a bubble bath extension hose is already known, as disclosed in Japanese Utility Model Publication No. 6-36954 and Japanese Utility Model Application Publication No. 56-98229. That is, in the former case, the other end of the hose is connected to the distal end of the spouting pipe to facilitate local pine surgery. The latter is connected to the jet discharge part of the bathtub with a threaded cap, and a hose is connected to the threaded cap with a gasket interposed therebetween for extension.

PROBLEM TO BE SOLVED BY THE INVENTION These known extension hoses have not been easily removable with external or threaded camp connections.

On the other hand, FIG. 6 shows an example of a configuration in which the jet discharge row of the bathtub can be easily connected in a detachable manner. A bead 15 is attached to the cylindrical soft connecting portion 8 formed to fit into the jet outlet with elastic force.
Press fit the resin cylinder 15 marked with a, and insert and fix the flexible hose part 16 with crow (7) on the outer periphery of the resin cylinder 15.Although not shown, the flexible connecting part 8 and the resin cylinder 15 Therefore, the number of assembly steps is large, and when inserting the flexible hose section 1 with a crow into the resin cylinder 15, the insertion pressure is large, which may damage the crow section or the flexible hose. Furthermore, during actual use (use in a bubble bath), the soft connection portion 8 and the resin cylinder 15 may come loose due to deterioration of the adhesive or the like.

In order to solve the above-mentioned problems, the present invention provides a bubble bath extension hose that is extremely easy to assemble, has a high yield, and has excellent durability even during actual use.

Means for Solving the Problems In order to achieve the above object, the bubble bath extension hose of the present invention is provided with a bead portion on the outer circumferential surface of the cylindrical soft connection portion, and a thread of the flexible hose portion is fitted into the bead portion. In addition, an elastic body is provided on the inner surface of the bead 1' portion to connect the soft connection portion and the flexible hose.

Function: With the above-described configuration, the present invention allows the soft connection part to be easily attached and detached from the jet nozzle part that generates air bubbles in the bath water, thereby eliminating the hassle of changing bodies in the bathtub and enjoying a bubble bath. This is an embodiment of a bubble bath that allows you to access each private part using an extension hose without having to change the direction of your body. 1 indicates a bathtub, a bathtub water circulation port, an inlet 2 at L7, and a discharge port 3 are provided on the side surface (wall surface) of the bathtub 1, and a circulation pump 5 is further provided in a circulation path 5a connected to both eyes. Thereby, the bath water is circulated W1.

The discharge port 3 has an intake path 4a that sucks air through the air solenoid valve 4 by the ejector effect of the jet water discharged into the bathtub 1. Therefore, when the air electromagnetic valve 4 is opened, air bubbles are mixed into the bath water discharged from the jet nozzle 7 at the tip of the discharge port 3 as shown in FIG. 5, and the bubble bath becomes iiJ function.

Then, when the soft connection part 8 of the bubble bath extension hose 6 of the present invention is attached to the IJt flow nozzle 7, a bubble jet is discharged from the other end of the bubble bath extension hose 6 as shown in FIG.
Apply a jet of air bubbles to local areas of the body to perform pine surge.

Figures 1a and 1b show an embodiment of the bubble bath extension hose of the present invention. A cylindrical soft connection part 8 made of natural or synthetic rubber material has a flexible hose 6a attached at one end.
An annular groove 8a is formed into which the end of the annular groove 8a fits.
Of the outer flange 8b and inner flange 8c forming the outer flange 8b, the inner flange 8c is extended to form an annular bead portion 9 on the outer peripheral surface. The flexible hose 6a follows the shape of the bead portion 9)
A peak portion 10 and a valley portion 10a consisting of annular uneven stripes are continuously formed. Then, the inner #f9 of the flexible hose 6a with the fitted bead portion 9 is pushed by the elastic body 11 provided inside this and is reliably joined to the flexible hose 6a. Not shown in FIG. 1a, the elastic body 11 is a plate spring,
The elastic body 12, not shown in FIG. 1, uses a coil spring. The soft connecting portion 8 is made of natural or synthetic rubber material (CR, NBREPDM, etc.).
A plurality of bead portions 9, which are annular convex portions, are formed on the outer peripheral surface.

FIG. 2 shows another embodiment of the present invention, in which the same parts as in the above embodiment are denoted by the same reference numerals, detailed explanation is omitted, and different parts will be mainly explained. That is, the plate spring 1 is arranged so that the elastic body 11 explained in FIG.
1, a protrusion 13 is provided on the inner surface of the inner collar 8c of the soft connecting portion 8.

FIGS. 3a and 3b show another embodiment of the present invention, in which the same parts as in the above embodiment are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained. That is, the plate spring material 11
A fixing hole (round hole) 14 is provided in a part of the plate spring material 11, and a protrusion 17 provided on the inner flange 8C of the soft connecting portion 8 is engaged with this hole using its elasticity. The structure is such that it prevents the object from moving.

Effects of the Invention As is clear from the above embodiments, the present invention has a simple structure, allows the soft connection portion and the flexible hose to be firmly joined, and has excellent durability.

Moreover, even if a load is applied to the soft connection part, it can be prevented from being damaged.
