Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle for a water faucet in which a display piece with a desired display such as a temperature scale is enclosed.

Hitherto, various structures of this type of faucet handle have been known, and a representative example is the one disclosed in West German Patent Application No. 2,115,818, shown in FIG.

Therefore, to explain the one shown in Fig. 4, the handle consists of a synthetic resin hook 1, a transparent synthetic resin handle body 5, and a decorative piece 4, which are each formed separately in advance. 1 fits into the handle body 5, and the decorative piece 4 fits into the recess 1' provided on the outer peripheral surface of the bushing 1.
It is contained in

The gap between the recess 1' and the inner circumferential surface of the handle body 5 is such that only the upper and lower ends are in contact with each other due to the overlap between the bush 1 and the handle body 5, creating a space.

In the conventional products described above, no matter how accurately and precisely the handle body and the bushing are molded, it is impossible to completely cover the entire surface between them and create no gap at all, and therefore the boundary between the two is impossible. Sewage, foreign matter, etc. may enter the parts, staining the decorative pieces, or making the transparent parts unclear, spoiling the aesthetic appearance.

Therefore, in order to prevent dirt from directly adhering to the display part, the cylindrical handle body with a bottom is molded from a transparent material, and the display part can be viewed through the handle body, for example, by using a special method. It is conceivable that the display part of the cap-shaped bushing seen in 1982-9122 be provided on the outer peripheral surface of the opening end side of the bushing, but the boundary line between the bushing and the handle body is the lower end face of the handle. Since it is exposed to the side, there is a drawback that a gap is likely to be formed at the boundary line, and dirt can enter, making it impossible to visually see the display section.

The reason for this is that the boundary line between the bushing and the main body of the faucet is located on the outer surface of the faucet handle, which is prone to dirt, and is exposed, and the display is located on that boundary line. be.

The technical problem to be solved by this invention is to make the boundary between the transparent handle body and the bushing, which has a display piece on the outer circumferential surface of the open end, to prevent dirt from adhering to the interior of the handle. The purpose is to position it on the surface.

The authority taken to achieve the above-mentioned technical problem is a faucet fitting consisting of a handle body made of transparent synthetic resin covering the outer surface of a synthetic resin bushing that opens downward and is formed into a cap shape. A display piece indicating the operation of the faucet is provided by wrapping around the outer peripheral surface of the opening end of the bushing, and a display piece that projects toward the center of the inner peripheral surface of the opening end of the handle body is provided on the top surface thereof. The bushing has a flange that comes into close contact with the opening end surface of the bush.

Thus, the boundary line between the handle body and the bushing can be located on the inner surface of the handle.

Since the present invention has the above configuration, it has the following advantages.

■ In the unlikely event that a gap is created at the boundary between the bushing and the handle body and water or dirt enters this gap, the dirt caused by water or dirt will be visible from the circumferential direction of the handle. The gap between the outer circumferential surface of the bushing and the inner circumferential surface of the handle body is not immediately reached, but the sealing action is performed by the close contact between the opening end face of the bushing and the flange of the handle body that covers this end face. The dirt covers the opening end of the bushing and this end.While it is in the gap between the flange of the handle body, this dirt is hardly visible from the circumferential direction of the handle, and the flange of the handle body covers the opening end of the bushing. By covering them, the inner diameter of the boundary line between the two is reduced by the thickness of the opening of the bushing, and the length of the boundary line is shortened, which synergistically reduces the gap area through which water and dirt can enter. The clarity and transparency of the display piece remains unchanged over a long period of time.
You can maintain the beauty of your hair.

■ Since the flange of the handle body is located at the end of the opening of the bushing, the opening end face of the bushing is protected by the flange of the handle main body, and the bushing and display piece are protected.
It will not fall off from the handle body.

■ Since the boundary line between the handle body and the bushing is not on the outer surface of the handle, the outer surface is completely smooth and has a good texture.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a bushing made of synthetic resin such as ABS resin, which is formed into a cap shape with one side open and the other side a truncated polygonal pyramid surface 2, and has a through hole 3 in the center of its top.

Moreover, this bushing 1 is colored and is non-transparent.

Coloring of the bushing 10 can be done by molding the bushing 1 from a synthetic resin mixed with a coloring agent in advance, or by forming a colored layer on the outer surface of a synthetic resin molded with no coloring agent by vacuum deposition, painting, or plating. Do by doing.

4 is a display piece, which is cut into thin strips of paper, aluminum foil, synthetic resin board, etc., and has the necessary markings, for example, if this handle is a temperature setting handle for a thermostat, a temperature scale or numbers representing the temperature. In the case of a mixing valve, print the blue and red colors that indicate the temperature of the mixed water, or the operating instructions for the handle, wrap it around the outer surface of the opening side of the bushing 1, and fix it with glue. do.

5 is the main body of the handle, which is molded integrally with the outer surface of the bushing 1 using synthetic resin such as transparent acrylic resin.
is installed and fixed in the mold of the injection molding machine of the handle body 5, and has a melting point lower than that of the bush 1 (or a bush 1).
(If the outer surface of the needle body is coated with plating etc., it may be made of a material having almost the same melting point as that.) A transparent synthetic resin liquid is injected into the mold, and at the same time as the transparent needle body 5 is formed, this and the bushing 1 are formed. They are integrated, that is, integrally molded.

At this time, part of the handle body 5 is fitted into the through hole 3 of the bushing 10, and the other part is fitted into the end face of the opening of the bushing 1, and the flange is shaped to hold the bushing 1. A section 16 is formed.

Reference numeral 16 denotes a flange provided on the inner circumferential surface of the open end of the handle body 5, which protrudes toward the center of the handle body 5, and whose top surface is in close contact with the open end surface of the bushing 1 to allow the body 5 to be inserted from the open side. Cover the boundary between the area and the area to ensure that water, dirt, etc. do not enter the area.

At the center of the top surface of the housing and handle body 5, a screw insertion hole 6 is bored which passes through the center of the top surface of the bush 1 and exits into the bush 1.

Therefore, a display piece 4 is sandwiched between the handle body 5 and the bushing 1 with both the front and back sides in close contact with both, and the space between the three is filled with transparent synthetic resin so that there is no gap between them. .

In this embodiment, the display piece 4 is attached to the bushing 1, but it may be fixed by means other than adhesion, for example, by using the elasticity of the display piece 4, or by providing a protrusion on the display piece 4 and a groove on the bushing 1.
Both may be engaged.

The faucet handle A is attached to the spindle 8 of the faucet B by aligning the predetermined position of its display portion 4 with the mark 7 shown on the faucet B. A handle attachment bushing 9 is interposed between the handle and the handle A.

The handle attachment bushing 9 is the bushing 1 of the handle A.
It has a truncated polygonal pyramidal surface 10 corresponding to the truncated polygonal pyramidal surface 2 of the truncated polygonal pyramid, and a spindle engagement 12 provided with female serrations 11, and the engagement hole 12 is connected to the male serration 13 of the spindle 8. The surfaces 10 are respectively engaged with the truncated polygonal pyramidal surfaces 2.

Note that the female serrations 11 are formed of metal, and are inserted into the bushing 1 to be integrated with the bushing 1. After putting the bushing 1 into the mold of the ndle main body 5, the ndle main body 5 is integrally molded. It's okay.

Numeral 14 is a screw that prevents the handle A from falling off, and is screwed into the threaded hole 15 on the tip of the spindle 8 from the top side of the handle A through the screw insertion hole 6.
