DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a side view showing an attached state of a faucet device according to the present invention, FIG. 2 is a sectional view of a main part, and FIG. FIG. 3B is a partially enlarged sectional view of the male screw member, and FIG.
Is an enlarged sectional view of a main part.

In the figure, reference numeral A denotes a faucet device, which is a self-closing faucet in this embodiment, and a main body 1 of which is provided with a self-closing valve mechanism (not shown) inside and is attached to a hand-washing machine 2;
The spout 3 faces the ball 4.

The main body 1 is formed so as to be inclined forward by about 20 degrees with respect to a vertical axis when attached to the hand-washing machine 2, and a handle 5 for opening and closing a self-closing valve mechanism is provided above the main body 1.
Is provided.

The handle 5 is made of, for example, a metal such as brass or a synthetic resin such as ABS, and has a flat surface with a bottom opening of about 60 mm.
It is formed into a cylindrical shape with a bottom of φ, its plane shape is a circle of about 60φ, and its upper surface is about 100 mm from the periphery to the center
The bulge 6 bulges upward with a radius of curvature of, and the peripheral edge is rounded so as not to be an edge.

The center of the lower surface of the handle 5 is formed to be thick so as to form a mounting hole 7, and a screw hole 8 is formed at the side rear portion of the handle 5. Has been reached.

The operation shaft 9 is formed in an elongated cylindrical shape, and a peripheral groove 10 having a triangular cross section is formed on the outer periphery of the upper end, and the upper end of the operation shaft 9 is inserted into the mounting hole 7, and the screw hole 8 is formed. The operation shaft 9 is attached and fixed to the handle 5 by engaging the distal end conical portion 12 of the male screw member 11 screwed into the peripheral groove portion 10.

The male screw member 11 is provided with a slit portion 14 at the tip of a screw thread 13 as shown in FIGS. 3A and 3B. When the male screw member 11 is screwed into the screw hole 8 as shown in FIG. The thread 13 is compressed by the thread valley 15, and the slit portion 14 is elastically deformed inward, so that the slit 13 closely adheres to the thread valley 15.

A female thread 16 is provided on the inner periphery of the lower portion of the operation shaft 9 and is slidably mounted in a guide bush 17 of the main body 1 while being constantly urged upward by a spring 18.

A spindle shaft 19 is screwed into the female thread portion 16 of the operation shaft 9, and the tip of the spindle shaft 19 extends into the main body 1 and faces the valve body 20 of the self-closing valve mechanism. It is configured such that the self-closing valve mechanism is opened by depressing 20.

Reference numeral 21 denotes an elastic body such as a polyacetal resin provided at the upper end of the guide bush 17, which suppresses shock absorption and noise generation when the handle 5 is pressed down and the peripheral edge of the mounting hole 7 of the handle 5 abuts. It is provided for.

In use, the handle 5 is held by the palm.
When the is pushed down, the operation shaft 9 and the spindle shaft 19 move downward, the tip of the spindle shaft 19 abuts on the valve body 20 and pushes it down, the self-closing valve mechanism opens, and water is discharged from the water discharge port 3.

At the time of this pushing-down operation, the bulging portion 6 of the handle 5 fits into the depression of the palm and becomes less slippery, and the operating direction of the handle 5 is inclined forward at an angle of about 20 degrees with respect to the vertical plane. Therefore, it is possible to easily open and close the door by easily applying weight.

Further, since the diameter of the handle 5 is set to about 60φ and the radius of curvature of the bulging portion 6 is set to about 100 mm, the handle 5 fits in the depression of the palm and fits into the depression, so that the operability is extremely good.

When the hand is released from the handle 5, the handle 5 automatically returns by the spring 18, but the water discharge is continued by the self-closing valve mechanism, and the water closes after a while.

When the handle 5 is depressed, the peripheral edge of the mounting hole 7 of the handle 5 abuts against the elastic body 21 and the impact force is applied to the operation shaft 9 and the male screw member 11 so that the male screw member 11 can be moved. Although the loosening function works, a frictional force due to the elastic stress generated by the slit portion 14 is generated between the thread 13 and the thread root 14, and the loosening of the male screw member 11 is prevented.

Of course, the impact force is reduced by the presence of the elastic body 21, and the circumferential groove 10 having a triangular cross section and the male screw member 1 are formed.
Since the impact force is divided by the engagement with the first conical portion 12, the loosening prevention effect is further enhanced.

The present invention can be variously modified without being limited to the above-described embodiment. Like the ordinary single faucet or the hot and cold water mixing faucet, the operating shaft is provided with an internal thread in the axial direction, and the handle is provided. Can be applied to a type in which is fitted to an operation shaft and fixed with a male screw member.

The slit portion does not need to be provided over the entire length of the male screw portion of the male screw member, but may be provided in a partial range, or a plurality of slit portions may be provided.

[0026]

The present invention controls the valve mechanism provided inside the body by operating the handle as described above, and controls the valve mechanism provided inside the body, and fixes the handle and the operation shaft with a male screw member. In the device, a slit portion is provided at the tip of the thread of the male screw member, so that the slit at the tip of the thread of the male screw member generates spring force against the thread valley of the female screw and closes tightly against the female screw to prevent loosening. The effect is obtained, and the locking effect is stable without the need for an adhesive or the like, and the locking effect can be obtained even when repeatedly attached and detached.
