Abstract

PURPOSE:To eliminate uncomfortable sound upon operation, by linealy welding a handle inner and a handle body together in their joint sections in the vicinity of both ends thereof. CONSTITUTION:A synthetic resin handle inner 12 which is formed in a substanaially bell-like shape is locked to the outwardly projecting end of a tap rod 5 by a screw, and is fitted thereto with a synthetic resin handle body 14 having a shape covering the outer peripheral surface of the handle inner 12. Further, since the handle inner 12 and the handle body 14 is welded together in their joint sections in the vicinity of both ends thereof, vibration which is generated in the threaded section of the tap rod 5 upon screwing operation of the rod 5 is transmitted to the handle inner 12 through the screw 16 but is not directly transmitted to the handle body 14, thereby vibration energy is absorbed and damped when it is transmitted to the handle body 14 having a large mass, and therefore, is not dissipated as sound to the outside.

Description

[Detailed description of the invention] [Industrial application field] Faucet handles such as water taps, stop valves, and hot/water mixing faucets.

[Prior Art] Fig. 3 shows a conventional faucet and its handle in cross section. In the figure, 1 is the faucet main body, 2 is the valve seat, 3 is the spout, 4 is the cylindrical part, and 5 is the cylindrical part. A stopper rod 6 is screwed into the cylindrical portion 4, and 6 is a stopper rod 5.
7 is an annular plate placed over the upper end opening of the cylindrical part 4, 8 is a rubber seal to prevent water leakage in that part, and 9 is a cap nut for holding the rubber seal 8. be. A screw hole 10 is formed in the axis of the outwardly projecting end of the stopper rod 5. On the other hand, a spline groove 11 is carved on the outer periphery of the edge. Reference numeral 12 denotes a handle inner made of ABS resin and formed into a substantially bell shape. An annular metal fitting 13 is integrally embedded in the inner periphery of the handle inner, and a spline groove engraved on the inner periphery of the annular metal fitting 13 corresponds to the spline groove 11. It meshes with.

Reference numeral 14 denotes a handle body made of transparent acrylic resin and shaped to cover the outer peripheral surface of the handle inner 12. A screw 16 is inserted into the center hole 15 of the handle body 14, and the screw 16 is inserted into the screw hole of the stopper rod 5. 10 is screwed and tightened.

In addition, 17 is a washer interposed on the lower surface of the head 18 of the screw 16, 19.20 is a wire welded part formed by ultrasonically welding the joint between the handle inner 12 and the handle body 14, and 21
1 shows a cap fitted into the central recess on the upper surface of the handle body 14 to hide the head 18 of the screw 16.

[Problems to be Solved by the Invention] In the upper and conventional faucets, the water flow state is controlled by grasping the handle body 14 and screwing the faucet rod 5 to press the elastic valve 6 onto the valve seat 2. However, when the elastic valve body 6 is pressed against the valve seat 2, a reaction force is applied to the stopper rod 5. Therefore, due to the friction between the threaded groove on the inner periphery of the cylindrical part 4 and the threaded groove on the outer periphery of the stopper rod 5, the metal pieces strongly rub against each other and generate vibrations, which are transmitted from the stopper rod 5 to the handle body 14 and the handle inner 12.
The transmission was directly transmitted to the metal, causing resonance in that part, producing a high-pitched metallic sound that sounded like a ``squeak'', which caused discomfort during operation.

[Objective of the Invention] To reduce or eliminate the unpleasant metallic sound generated by the threading of the tap rod in a water faucet by improving the structure of the handle.

[Means for Achieving the Purpose] In a faucet that controls water flow by pressing an elastic valve element onto a valve seat by screwing a stopper rod, the outwardly projecting end of the stopper rod is provided with a bell made of synthetic resin. The shaped handle inner is screwed together, and a synthetic resin handle body shaped to cover the outer circumferential surface of the handle inner is fitted, and the handle inner and the handle body are connected to each other near one end. Line weld the joint and the joint near the other end.

[Operation] The vibration of the stopper rod is transmitted to the handle inner and then to the handle body, so the vibration is attenuated and does not cause resonance compared to when the vibration is directly transmitted from the stopper rod to the handle body.

[Example] FIG. 1 shows an example of the present invention. Note that the same reference numerals in FIG. 1 as in FIG. 3 represent the same or corresponding members. That is, a screw hole 10 is formed in the axis of the outwardly projecting end of the handle body 5, and a pline groove 11 is formed in the outer periphery, which is the same as in the conventional case. The substantially bell-shaped handle inner 12 made of resin has a cylindrical raised portion 3-22 formed at the center of its upper surface, and the inner diameter of the cylindrical raised portion 22 is made approximately equal to the outer diameter of the screw 16, and The outer diameter of the shaped raised portion 22 is made to approximately match the inner diameter of the upper part of the handle body 14.

Then, insert the screw 16 into this cylindrical raised portion 22,
The head 18 is inserted into the cylindrical raised portion 2 with the washer 17 interposed.
2, and screw the screw 16 into the screw hole 10. In addition, the handle inner 12 has an outer peripheral edge flange 23.
The handle body 1
4, and this solidly joined portion is ultrasonically welded to form a line welded portion 19.20, and a gap 24 is formed in the space between the line welded portions 19.20. As shown in FIG.
are reinforced by a plurality of radial ribs 27. Other details such as the material of the handle body 14 and the fact that the cap 21 is fitted into the central recess on the upper surface thereof are the same as those in FIG. 3.

In the faucet handle configured in this manner, vibrations generated at the threaded portion of the faucet rod 5 when the faucet rod 5 is screwed are transmitted to the handle inner 12 via the screw 16 and directly to the handle body 14. is not transmitted. Therefore, even if vibrations are transmitted to the handle inner 12, the energy of the vibrations is absorbed and attenuated when transmitted to the handle body 14, which has a large mass, so that the amount of sound dissipated to the outside is minimized or completely eliminated. .

[Effects of the Invention] The unpleasant noise during operation, which is the biggest drawback of faucets in which the water flow is controlled by pressing an elastic valve body onto the valve seat, can be eliminated, and the product value can be improved.
