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 upper cover and an undercover are engaged to form a faucet shell, and a metal water pipe member is installed inside the faucet shell.

[Problem that the invention attempts to solve]

When constructing a shell by engaging an upper cover and an undercover made of synthetic resin, difficulties tend to occur in the operation 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. The number of man-hours required for screwing in and screws increases.
Work costs tend to increase.

[Means for solving problems]

In the faucet of the present invention, a synthetic resin undercover and a synthetic resin upper cover are engaged to form a faucet shell, and a metal (e.g., cast metal) water pipe member is installed inside this shell. The faucet has a slender pillar protruding from one of the peripheral edges of the upper cover and the under cover, a recessed hole for fitting the pillar into the other, and a protrusion on the side peripheral surface of the pillar. When the pillar is inserted into the recessed hole, the protrusion is crushed to engage the upper cover and the undercover.

[Function] In the faucet of the present invention, the shell body is constructed by simply covering the under cover with the upper cover and then pushing the pillar into the recess. During this pushing, the protrusion on the pillar-side circumferential surface is crushed against the inner circumferential surface of the recessed hole, filling the gap between the pillar and the recessed hole, and firmly attaching the pillar to the recessed hole. Therefore, the strength of the attachment between the under cover and the upper cover is extremely high. Furthermore, no tapping or screwing work is required when manufacturing the faucet, making manufacturing and assembly extremely easy. Of course, both the upper cover and the under cover are made of synthetic resin, and even complex shapes can be molded and manufactured very easily.

〔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, an under cover 12 made of synthetic resin, and a water passage pipe 14 made of cast iron. The undercover 12 includes a bottom seat part 12a that is seated on the top surface of the washbasin, and a water spout part 12b that extends forward from the center of the bottom seat part 12a. A hook portion 16 is integrally formed. 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 spout cover part 1 that covers the water spout part 12b.
0b. Also, under cover 12
A plurality of slender pillars 18 (six in total in this embodiment) are erected on the peripheral edge of the upper cover 10, and the upper cover 10 has an engaging hole 20a that engages with the pillar 18. A stop part 20 is provided,
The upper cover 10 and the under cover 12 are engaged with each other by the engagement between the pillars 18 and the recessed holes 20a, thereby forming a faucet shell 22. As shown in an enlarged view in FIG. 4, a protrusion 18a (in this embodiment, a protrusion extending in the longitudinal direction of the pillar) is provided on the side peripheral surface of the pillar 18. 20a, this protrusion 18a is crushed and fills the gap between the inner peripheral surface of the recessed hole 20a and the outer peripheral surface of the pillar 18, making it possible to firmly connect the pillar 18 and the recessed hole 20a.

Therefore, in order to engage the pillar 18 and the recessed hole 20a, it is only necessary to put the upper cover 10 on the under cover 12 and then push it in with a little force, so this assembly can be performed extremely easily and quickly. . Further, since the upper cover 10 and the under cover 12 are both made of synthetic resin, the pillars 18 and the locking portions 20 can be integrally molded, and the manufacturing thereof can be performed extremely cheaply and easily. Note that the upper cover 10 and the undercover 12, especially the upper cover 10, may be plated or colored to enhance their 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 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 pillar 18 is provided protrudingly on the under cover 12 and the locking portion 20 is provided on the upper cover 10, but on the contrary, the pillar is provided on the upper cover 10 and the locking portion is provided on the under cover. It may also be provided. Furthermore, the shape of the protrusions provided on the pillars is not limited to that shown in the figures, and the number of pillars and protrusions provided is also not limited to that shown in the figures.

[Effect of idea]

As described above, the present invention constructs a faucet shell by connecting an easily moldable synthetic resin upper cover and an undercover, and installs a metal water pipe member inside this shell. It is extremely easy to mold and assemble the shell, and it is inexpensive. 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.

Furthermore, since the upper cover and the under cover are connected to each other through the pillars and the recessed holes, there is no need for tapping or the like, and the so-called one-touch assembly can be performed, making manufacturing and assembly extremely easy. Also,
Since the protrusion is provided on the peripheral surface of the pillar, the fitting between the pillar and the recessed hole is extremely strong, and the engagement strength between the under cover and the upper cover is also sufficiently large.
