DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the water supply pipe of the faucet, to piping hoses for use in the piping of the hot water supply pipe.

[0002]

2. Description of the Related Art A TPE hose made of a thermoplastic material is
Compared to copper pipes that have been used in the past, they are flexible and easy to bend into any shape, and can be easily constructed, so they have come to be widely used for connecting pipes. Fig. 4 shows TP
A water faucet installed on a wash basin or the like is connected to a check valve using an E hose. Briefly describing FIG. 4, a faucet 32 is fixed to a top plate 31 such as a wash basin or a sink.
Non-return valves 33, 33 provided below the top plate 31 and connected to a water supply source and a hot water supply source are connected to the water flow path and the hot water flow path of the faucet 32 by TPE hoses 34, 34, respectively.
Since the hoses 34, 34 are made of resin, the entire peripheral surface is covered and protected with stainless steel blades 35, 35, so that the T
The PE hoses 34, 34 are prevented from slidingly contacting each other when the faucet is opened and closed, and from being damaged by collision with other objects.

[0003] In the above, stainless steel blades are extremely expensive and expensive, and when coated with a hard stainless steel blade, the TPE hose is less likely to bend, which is an advantage of the TPE hose. However, there is a drawback that it cannot be expected that the construction is easily performed due to the deformation.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a piping hose which can be reduced in cost and has excellent workability.

[0005]

According to the present invention, the outer circumference of a TPE hose made of a thermoplastic material is wound with a fiber blade, and the outer circumference of the fiber blade is further covered with a urethane blade . It is used for piping of a water supply pipe and a hot water supply pipe .

[0006]

DETAILED DESCRIPTION OF THE INVENTION The piping hose the outer periphery of the TPE hose wound around a fiber braid, than was further coated with a urethane blade outer periphery of the fiber blade, water supply pipe of the faucet,
When used in pipes of the hot water supply pipe can be bent easily,
After perform a pipe connection work in a short period of time, Ru can measure the cost down.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the present invention comprises a faucet 1 attached to a top plate A of a wash basin or a sink, and a check valve 2, 2 disposed below the top plate A and communicating with a water supply source or a hot water supply source. It is connected to piping hoses 3,3.

As shown in FIGS. 2 and 3, the piping hoses 3, 3 are covered with a TPE hose 4 with a spring 5 interposed therebetween and the outer periphery wound continuously with a fiber blade 6 in the longitudinal direction. Further, the outer periphery of the fiber blade 6 is covered with a urethane blade 7.

The TPE hose 4 has a rubber elasticity and does not exhibit plasticity at around normal temperature, but is formed of a resin having a property of being softened and deformed to another shape when heated to a high temperature, with a spring 5 interposed therein. By doing so, the TPE hose 4 is not easily deformed even if a force in the bending direction is applied to the TPE hose 4 by the elastic effect of the spring 5.

The fiber blade 6 is made of a flexible material such as nylon, and is used to provide strength against water pressure rupture and tensile rupture. By winding over
The strength of the PE hose 4 is maintained.

The urethane blade 7 is formed of a flexible material having excellent slidability and chemical resistance. The urethane blade 7 is formed of a flexible material so as to prevent the fiber blade 6 from being extremely damaged by being damaged. The periphery is covered.

The piping hose 3 configured as described above has a T
Fiber protection PE hose 4 and strength retention, the use of the blade made of a flexible material such as urethane, Ki out easily bent as compared with the conventional piping hose stainless blade coated, water Of the water pipe and hot water pipe of the tap 1
Fibers blades and urethane blade after the construction stage performance is significantly improved when using the pipe can measure the cost can be manufactured at low cost.

[0013]

Since the present invention has the above configuration, it has the following advantages. (1) Since the outer circumference of a TPE hose made of a thermoplastic material is wound with a fiber blade and the outer circumference of the fiber blade is further covered with a urethane blade, a conventional T
Ki out bending compared to readily to those outer periphery coated stainless blade of PE hose, the water supply pipe of the faucet, feed
Fiber blades and urethane blade terms of the construction stage of the case, which was used for the piping hot water pipe is greatly improved can measure the cost down can be manufactured at low cost.
