Description

[Detailed description of the invention] [Field of industrial application] The invention consists of a shell consisting of an upper cover and an undercover made of synthetic resin, and a metal water pipe member is provided inside this shell. It concerns faucets.

[Conventional technology]

Traditionally, faucets have been made of cast metal,
Because the shape is complex, a casting method using a sand mold must be used, and the surface of the cast must be carefully finished by grinding, polishing, etc.
Production costs tended to increase.

Therefore, in recent years, consideration has been given to making faucets made of synthetic resin that is easy to mold. That is, a synthetic resin or metal upper cover and a synthetic resin undercover are connected to form a faucet shell, and a metal water pipe member is installed inside this faucet shell. .

[Problem that the invention attempts to solve]

When constructing a shell by engaging such an upper cover and an undercover, difficulties tend to occur in the work of engaging the upper cover and the undercover. In other words, in order to connect the upper cover and the under cover, for example, screws may be used, but in order to securely and firmly connect the upper cover and the under cover, it is necessary to provide a large number of screw holes, which takes time and effort. This increases the number of man-hours required to screw in screws and screws, which tends to increase work costs.

[Means for solving problems]

The faucet of the present invention has a faucet shell made up of an under cover and an upper cover made of synthetic resin that are connected to each other.
This faucet has a water pipe member made of metal (for example, cast iron) installed inside the shell, and the spout is passed through the tip of the undercover and screwed onto the lower surface of the tip of the water pipe member. , a flange portion is provided around the base, and an undercover is supported by the flange portion.

[Effect]

In the faucet of the present invention, since the undercover is supported by the flange portion of the spout, the fixing strength of the undercover is extremely high.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an assembled perspective view of the main parts of a hot water mixing faucet according to an embodiment of the present invention, FIG. 2 is a side sectional view of the hot water mixing faucet, and FIG. 3 is a perspective view of an undercover.

The hot water mixing faucet according to this embodiment has an upper cover 10 made of synthetic resin or metal, an under cover 12 made of synthetic resin, and a water pipe 14 made of cast metal. The undercover 12 includes a bottom seat portion 12a that is seated on the top surface of the washbasin, and a bottom seat portion 12a that is seated on the top surface of the washbasin.
The water spouting part 12b is provided with a water spouting part 12b extending forward from the center of the water spouting part 12b, and a chain hook part 16 is integrally formed on the lower surface side of the water spouting part 12b. The upper cover 10 has a shape that covers the undercover 12 from above, and includes a main body part 10a that covers the bottom seat part 12a, and a water spouting cover part 10b that covers the water spouting part 12b. In addition, the undercover 12 has a plurality of claws 18 (three in total in this embodiment) on both sides of the water spouting part 12b and at the tip.
The water discharge cover portion 10b of the upper cover 10 is provided with a locking portion 20 consisting of a recessed hole that engages with the claw 18. As a result, the upper cover 10 and the under cover 12 are engaged, and the faucet shell 22
It consists of If the upper cover 10 is made of synthetic resin, it may be plated or colored to enhance its aesthetic appearance.

The water pipe member 14 has a base end 14a and a water discharge part 14b extending forward from the base end 14a, and the base end 14a has a water leg 24 and a hot water leg 26. are connected. In addition, the base end portion 14a
Valve cases 28 and 30 are provided on the upper surface side, and are used to stop and adjust the flow rate of water and hot water flowing from the water leg 24 and the hot water leg 26 to the base end 14a of the water pipe member 14. It's becoming like that. Note that the main body portion 10a of the upper cover 10 has a hole 3 for inserting a spindle (not shown) projecting upward from the valve casings 28, 30.
2, 33 (33 is not shown) are provided,
A hot water handle (not shown) and a water handle 34 are attached to the upper end of this spindle. Further, the bottom seat portion 12a of the undercover 12 is provided with through holes 36 and 38 through which the water leg portion 24 and the hot water leg portion 26 are inserted.

A water outlet 40 is opened at the tip of the water pipe member 14, and a water outlet 12b of the undercover 12 is opened.
An opening 42 is provided at the tip, and a spout cap 44 can be screwed onto the spout 40 through the opening 42. A flange portion 44a is provided around this base 44, and this flange portion 44
a supports the water spouting portion 12b of the undercover 12 from below.

A chain 46 is secured to the hook portion 16 via a chain connection fitting 48 and a ring 50, and a drain cap 52 is connected to the tip of the chain 46 via a similar connection fitting 48 and ring 50. installed. Note that the bottom seat portion 12 of the undercover 12
A is a bolt 54 attached to the base end 14a of the water pipe member 14.
It is fixed in place.

In the faucet configured as described above, water and hot water supplied from the water leg 24 and the hot water leg 26 are passed and stopped by valve bodies (not shown) in the valve casings 28 and 30. The water flows out through the base end 14a of the water pipe member 14 while being subjected to flow rate control.

In the above embodiment, the under cover 12 is provided with a protruding claw 18, and the upper cover 10 is provided with a locking portion 20.
Although the upper cover 10 is provided with a recess, a claw may be provided on the upper cover 10 and a locking portion may be provided on the under cover. Furthermore, the shapes of the claws and the locking portions are not limited to those shown in the drawings, and furthermore, the number of the claws and the locking portions to be installed is not limited to those shown in the drawings. For example, a thin columnar projection and a recess into which the projection fits may be used. Furthermore, screws may be used instead of these. Since the flange portion 44a of the cap supports the undercover 12, extremely firm engagement between the undercover and the upper cover is possible even if the number of such engagement means is reduced. .

[Effect of idea]

As described above, the present invention consists of an upper cover and an undercover that are connected together to form a faucet shell, and a metal water pipe member is installed inside this shell. , assembly is extremely easy,
And it's cheap. In addition, even if the water pipe member is a cast product, no special surface finishing work is required, and it is easy and inexpensive to manufacture. Since the undercover is supported by the base, the strength of the attachment between the undercover and the upper cover can be sufficiently increased, and the number of screws, locking claws, etc. can be reduced, making production easier. Assembly etc. becomes easy.
