Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle device for a drain faucet, and more particularly to an improvement in a handle device that vertically rotates the handle to raise and lower a valve body.

In recent years, for drain valves, instead of the conventional method in which the handle is turned horizontally and the valve body is raised and lowered by a screw, for example,
No. 55-43335, a system in which the valve body is raised and lowered by vertical rotation of a lever without using screws has been proposed.The structure is simple, and the valve body is moved naturally by water pressure or the rod's own weight. It is effective in opening and closing, that is, preventing self-propulsion, and has advantages such as being able to confirm whether the tap is completely opened or closed, so it is gradually becoming mainstream.

However, in the above-mentioned Utility Model Publication No. 55-43335, the lever rotates vertically, but the stop position is horizontal, so it is difficult to determine whether the valve is open (water flowing) or closed (water drained). The drawbacks were that it was difficult to check from a distance, and when it was installed in a corner of a room, the lever hit the wall and could not be operated.

Therefore, this invention allows the lever to rotate within 180 degrees vertically, allowing the handle to be operated no matter what corner it is mounted in. Depending on whether the lever is facing upwards or downwards, the open/closed state can be seen from a distance. The purpose of this invention is to provide a handle device for a drain valve that can be checked even if the user does not know the situation. In order to achieve the above object, the present invention connects a support body to the upper end of a pipe extending upward from a valve box of a drain valve, connects an operating body to the upper end of the support body with a nut, and An operating lever having a bifurcated joint at one end is hinged to the side of a notched window provided at the front end of the operating body, and is connected to the upper end of a rod extending from the valve body that moves up and down within the valve box. Insert the operating rod into the bifurcated joint, connect the operating lever with a pin through the small-diameter horizontal groove at the upper end and the large-diameter groove adjacent to it, and rotate the operating lever by rotating the operating lever within 180 degrees perpendicularly. In addition to making it move up and down, the pin of the operating lever is positioned in the large diameter groove in the fully open and fully closed states, and a torsion spring attached to the outside of the operating lever constantly applies pressing force to the operating lever. This is the perfect way to prevent self-propulsion.

The present invention will be described below with reference to embodiments shown in the drawings.

In Figs. 1 and 2, 1 is a pipe, which is connected to a valve box of a drain plug buried underground at its lower end (not shown), and is extended to the above ground, and connected to a support main body 2 at its upper end. do. Reference numeral 3 denotes an operating section main body whose upper end is closed, and the supporting section main body 2 is connected by a nut 4.
Connected and fixed to the top end of the Reference numeral 5 denotes an adjustment nut, which is used to easily adjust the stroke from the outside, and also serves to prevent the nut 4 from falling. The operating section main body 3 has a vertically long rectangular cutout window 6 formed at its front end, and protrusions 7 on both sides thereof. 8 is an operating lever, and a pin 9 is attached to the projection 7.
It is hinged and has a bifurcated joint 10 at one end. Reference numeral 11 denotes a rod housed within the pipe 1, which extends upward from the valve body (not shown) that moves up and down within the valve box of the drain valve to shut off water, and connects an operating rod 12 to its upper end. The operating rod 12 is formed with a small diameter at the upper part so as to fit into the coupling part 10, and has a small diameter horizontal groove 13 at the upper end as shown in FIG.
A large-diameter groove 14 adjacent thereto is provided so as to open to the side. Note that this can also be provided without opening on the side, as shown in Figure 4.
Processing takes time, but the strength is greater. The pin 15 inserted into the tip of the coupling portion 10 of the operating lever 8 is engaged with the small-diameter lateral groove 13 and the large-diameter groove 14, so that the operating lever 8 and the operating rod 12 are coupled. Further, a pin 16 is inserted below the small-diameter horizontal groove 13 of the operating rod 12 with both ends protruding, and a bifurcated torsion spring 17 as shown in FIG. I try to apply pressure. Note that, in consideration of falling off, this is not an integral piece, and two identical torsion springs may be attached to both sides of the pin 16.

Next, the operation mode of the present invention will be explained based on the embodiment shown in the drawings.

1 and 2 show the operating rod 12, the rod 11, and the valve body connected to the rod 11 in the lowest position. At this time, the pin 15 has entered the large diameter groove 14, and Since the torsion spring 17 presses the operating lever 8 against the front wall of the operating section main body 3 and stops, the pin 15 enters the large diameter groove 14 even if the water pressure applies upward force to the valve body. Therefore, the operation lever 8 does not rotate by itself, and the valve body does not move by itself. From this state,

rotates around the pin 9, the pin 15 also rises, first escapes from the large diameter groove 14, and moves in the small diameter lateral groove 13 to the right in the figure in the first half of the rotation, and to the left in the second half of the rotation. Continue to rise. Along with this, the operation stick 12 also rises, and its upper end becomes the operation part main body 3.
It stops rising when it comes into contact with the top of the That is, the sixth
It will be in the closed (drainage) state as shown in the figure. Even in this state, the pin 15 enters the large diameter groove 14 again, and the torsion spring 17 acts as a force to rotate the operating lever 18 downward, so the rod 1

When it is lifted and rotated, the process reverses to that described above and returns to the state shown in Fig. 1.

In the example, the rotation angle of the operating lever is 120°
However, it is also possible to set it to any angle within 180°.

As mentioned above, although the present invention has a simple structure, it has a complete self-propelling prevention effect.
Whether the operating lever is in the up or down position allows you to easily identify whether the bottle is open or closed from a distance, and since the operating lever rotates vertically, the horizontal protrusion is reduced accordingly. Even if it is installed in the corner of the room, Nat4
If it is loosened, the main body 3 of the operating section can rotate freely, and there is no problem in operating the handle.
