Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet for supplying water or hot water, which is installed in a sink or washbasin for home or business use, or a bathtub, and more specifically, is attached to the faucet. The present invention relates to a faucet handle (handle) used when adjusting the amount of water and stopping the flow of water.

Many structures have been proposed for faucet handles. For example, in the old days, a plurality of horizontal propeller-type projections were provided radially, and the outer ends of these projections were connected by an annular holding part, with the handle and spindle (center) as the center. Those which are rotated to adjust the water flow, and more recently, as disclosed in, for example, JP-A-8-303620,
There is also a lever type. This lever type is designed to rotate and move in the horizontal direction (that is, the direction orthogonal to the axis of the spindle), or to move the packing in the cartridge up and down not only horizontally but also vertically. There are many types that are designed to control the flow of water and to distinguish and mix water / hot water.

However, in the conventional faucet handle, the spindle as the rotating shaft and the handle are not sufficiently coupled, and as disclosed in the above-mentioned Japanese Patent Laid-Open No. 8-303620, they are fixed with a single screw. Since it was easy to come off, it was difficult to withstand long-term hard use, and there was a problem with reliability. Further, in the case of the vertical movement type handle, in addition to the above problems, there is a risk of water leakage due to the structure of the internal sealing body due to the wear of the seal member in the internal cylinder.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and has a firm and stable engagement with a rotary shaft for adjusting the amount of water, that is, a spindle, and yet an operation for adjusting the amount of water. It is intended to provide a faucet handle that can be made smoothly.

And an enlarged diameter portion 7 provided at one end of the intermediate shaft portion 6, and a spindle engagement portion 8 provided at the other end of the intermediate portion 6, and the spindle engagement portion 8 has the central hole 3 A spindle receiving hole 9 is provided on the side orthogonal to the longitudinal direction of the above, and a first locking screw 10 is screwed into an end portion of the spindle engaging portion 8.
A second locking screw 11 is screwed into the center hole 3 in the intermediate shaft portion 6 and the enlarged diameter portion 7, and the spindle is formed by the first locking screw 10 and the second locking screw 11. 4 is locked from the opposite direction.

Therefore, the faucet body 1 is fitted in the spindle receiving hole 9.
Insert the rotatable spindle 4 attached to the
The locking screw 10 and the second locking screw 11 can be tightened by pressing the spindle from opposite positions. In this way, by screwing the two locking screws 10 and 11 from opposite directions, the locking portion of the spindle inserted into the spindle receiving hole 9 is tightened from both sides, and sufficient tightening is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, FIG. 1 showing the appearance of a faucet handle according to the present invention and FIG. 6 showing the whole faucet and handle.
In, the faucet handle 5 is formed of a corrosion-resistant metal such as brass. The handle 5 has a cylindrical intermediate shaft portion 6 which is a slightly narrowed portion as a whole, a spatula-shaped enlarged portion 7 formed continuously at one end thereof, and an integral portion continuously formed at the other end thereof. The formed engaging portion 8 is provided. The engaging portion 8 is a portion that engages with the rotating shaft of the water faucet body 1, that is, the spindle 4, as described later.

The handle 5 having the enlarged diameter portion 7 and the engaging portion 8 on both sides of the intermediate portion is provided with a central hole 3 extending to the entire internal length thereof. The expanded diameter portion 7 is formed in the shape of a spatula as described above, and has a flat plate shape on both sides thereof, and its expansion extends in the same direction as the axial direction of the spindle of the faucet body 1 described later. ing.

Next, the engaging portion 8 provided on the other end of the intermediate shaft portion 6 is formed with a receiving hole 9 for receiving the spindle 4 on one side thereof, and its inner end is closed by the wall of the engaging portion. Has been done. As shown in the drawing, the engaging portion 8 is formed to have a diameter slightly larger than that of the intermediate shaft portion 6. Furthermore, at the end of the engaging portion,
A screw hole 12 that communicates with a center hole described later is formed so that the screw hole 12 can be screwed into the first screw 10.

In FIGS. 1, 2, 3 and 6,
The handle 5 has a central hole 3 formed along its entire length.
Is equipped with. The center hole 3 is opened at both ends thereof and communicates with the spindle receiving hole 9 as well. One side (that is, the engaging portion 8 side) of the first locking screw 10 is inserted and the other side (that is, At the expanded portion 7 side), the second locking screw 11
The thread groove 1 into which the first locking screw and the second locking screw are respectively inserted at desired positions on the wall surface of the suspension hole 3.
2 and 13 are formed.

The faucet handle 1 thus constructed
Can be attached by a simple operation as follows. That is, as shown in FIG. 6, the upper end of the spindle which is rotatable from the bonnet 15 of the faucet body 1 and which is rotatable in a designated angle range is inserted into the receiving hole 9 of the handle of the present invention, and is fully inserted. , The spindles are pressed against each other only by rotating the first locking screw and the second locking screw 11, whereby the spindle 4 is gripped and tightened. Thus, the attachment of the faucet handle 5 is completed, and the desired handle operation can be achieved simply by touching and moving the enlarged diameter flat portion 14 of the enlarged diameter portion 7.

FIG. 4 shows a modification of the faucet handle of the present invention. In the embodiment of FIG. 2, the first screw and the second screw are
The tip is tapered, whereas the case of FIG. 4 is different in that the end is a flat surface. The other configuration is the same as that of FIG.

[0016]

As described above, the faucet handle according to the present invention has the central hole 3 formed therein over the entire length thereof, and the handle 5 has the intermediate shaft portion 6 and one end of the intermediate shaft portion 6. It has an enlarged diameter portion 7 provided and a spindle engaging portion 8 provided at the other end of the intermediate shaft portion 6, and the spindle engaging portion 8 is provided on the side orthogonal to the longitudinal direction of the central hole 3. A spindle receiving hole 9 is provided, a first locking screw 10 is screwed into the end of the spindle engaging portion 8, and a second hole is provided in the center hole 3 in the intermediate shaft portion 6 and the enlarged diameter portion 7. The locking screws 11 are screwed together, and the first locking screw 10 and the second locking screw 11 are engaged.
With this, the spindle 4 is locked from the opposite direction, so that the engagement of the water faucet body 1 with the spindle 4 is stable and strong, and thus stable operation can be maintained.

Further, the expanded diameter portion 7 has a flat surface portion 1 in the same direction with respect to the axis of the spindle 4 orthogonal to the central hole 3.
Since it has 4, the grip for operation is facilitated.

Further, a first screw groove 12 for screwing with the first screw 10 is formed in the center hole 3 at one end of the spindle engaging portion 8, and the center hole at the other end of the engaging portion 8 is formed. Since the second screw groove 13 that is screwed into the second screw 11 is formed in the screw 3, stable handle coupling can be achieved.
