[Conventional technology]

A low tank is one of the tanks used to supply flush water to Western-style toilets, and this low tank is a double-layered low tank in which the tank body (flush water tank) for storing flush water is surrounded by a tank cover. Are known. According to this double-layer low tank, there is a space between the outer surface of the wash water tank and the inner surface of the tank cover, so even if cold wash water is stored in the wash water tank, cold temperature will not be transmitted to the outer surface of the tank cover. This prevents dew condensation on the outer surface of the tank cover and prevents the toilet floor from getting wet.

This wash water tank is usually made of synthetic resin, while the tank cover is made of ceramic, which has an excellent appearance.

By the way, in such a double-layer low tank, a handle is attached as shown in FIG. 6 as a handle for operating a valve for supplying flush water from the low tank to the toilet bowl.

In FIG. 6, reference numeral 10 denotes a wash water tank which is the main body of the low tank, and a tank cover 12 made of ceramic surrounds the outside thereof. Openings 14 and 16 are formed in the upper side walls of the wash water tank 10 and the tank cover 12, respectively, and a handle is attached thereto.

[Problem that the invention attempts to solve]

In the conventional handle described above, the outer circumferential surface of the spindle with lever 20 and the inner circumferential surface of the mounting portion 18 come into contact with metal, so that wear is likely to occur. Therefore, it is conceivable to fit a resin sleeve into the lever-equipped spindle, but it is not easy to reliably prevent the resin sleeve from coming off.

[Means for solving problems]

In the present invention, the handle of the low tank includes a mounting portion attached to the side wall opening of the low tank;
A spindle with a lever inserted into this mounting part,
It mainly consists of a handle lever detachably attached to the tip of this lever-equipped spindle. The mounting part has a flange part that comes into contact with the edge surface of the side wall opening of the low tank, and the opening edge is held between a cover nut screwed onto the mounting part from the opposite side of the side wall opening. can be firmly attached to the low tank. A resin sleeve is fitted into the spindle with the lever from its tip side, and is fixed by a ring fixed to the spindle with the lever. Note that the attachment portion has a notch or an opening formed at its distal end side to enable the fixing operation of the ring.

[Effect]

When assembling the handle of this invention, first insert the spindle with lever into the insertion mounting part,
A resin sleeve is inserted from the distal end side. Then, a ring such as an E-link is fixed to the spindle through a notch or opening provided in the mounting portion to prevent the resin sleeve from coming off. Since the notch or opening is provided in this way, the E-ring etc. can be attached extremely easily.

〔Example〕

Examples will be described below with reference to the drawings.

Fig. 1 is an assembled perspective view of a handle according to an embodiment of the present invention, Fig. 2 is a perspective view of the main parts thereof, Fig. 3 is a vertical sectional view showing the installed state, and Fig. 4 is a line taken along the line - - in Fig. 3. FIG.

Reference numeral 42 denotes a substantially cylindrical mounting portion, which has a non-perfect circular cross-sectional shape. In this example,
The cross-section is a circle cut out into two parallel chord shapes. The mounting part 42 has a flange part 44 on one end side.
A spindle with a lever 20 is inserted into the center hole thereof. Further, a female thread 46 is formed in the center hole of the mounting portion 42 from the one end side.
A cover nut 48 is screwed into this female thread 46. The cover nut 48 includes a male thread 48a and a flange 48b.

The lever type spindle 20 is similar to that shown in FIG.
0a, and this chain hook 28
A chain 50 is hung on it. The spindle part of the spindle with lever 20 is inserted into the mounting part 42 as described above, and the resin sleeve 52 is inserted into this spindle part, and the tip of this resin sleeve 52 is inserted into the inner circumference of the mounting part 42. inserted between the surface and the outer peripheral surface of the spindle,
This prevents direct contact (metal touch) between the mounting portion 42 and the outer peripheral surface of the spindle with lever 20.

The resin sleeve 52 is fixed by an E-ring 54 inserted into the lever-equipped spindle 20. Further, the mounting portion 42 is formed by cutting in such a way that a notch 42a reaches the flange 44 from its distal end side. Therefore, after the resin sleeve 52 is inserted into the spindle 20, the E-ring 54 can easily fix the spindle 20 through the notch 42a. Note that the spindle 20 is provided with an E-ring insertion groove 20b around its circumference.

In this embodiment, the tip of the spindle with lever 20 is a serration shaft 30, and the serration groove 56a of the extension spindle 56 can engage with this serration shaft 30. A serration groove 5 is provided on the other end side of the extension spindle 56.
6b is provided, and this serration groove 56
b engages with the serration groove 32 of the handle lever 24. This handle lever 24 is fixed to the lever-equipped spindle 20 by a screw 22, and the screw 22 is screwed into the threaded hole 20b of the lever type spindle 20 through the center hole 56c of the extension spindle 56. Code 34 is a makeup cap;
58 is Patsukin.

Therefore, the mounting part 42 has a non-perfect circular shape with two parts of the circle cut out in parallel chord directions, and the opening 14 of the cleaning water tank 10 is also formed in this mounting part 42.
2, it is a non-perfect circular opening with two parallel cutouts in the chord direction of the circle. Note that the opening 16 is a perfectly circular opening.

To attach this handle to the low tank,
First, remove the cover nut 48 and the handle lever 24 as shown in FIG. 44 is engaged with the edge of the opening 14, and the mounting portion 42 is placed in the opening 14. In this state, the tank cover 12 is placed over the wash water tank 10, and then the cover nut 48 is inserted from the outside of the opening 16 and rotated. Then, the male thread 48a meshes with the female thread 46, and the mounting portion 4
2 is gradually drawn forward. Note that the mounting portion 42 and the opening 14 each have a non-perfect circular cross-sectional shape, so that even if the rotational force of the cover nut 48 is transmitted to the mounting portion 42, the mounting portion 42 itself does not rotate. When the cover nut 48 is sufficiently tightened, the flange portion 44 comes into contact with the back side edge of the opening 16, and the flange portion 48b and the flange portion 44 firmly clamp the edge of the opening 16, thereby attaching the nut. The portion 42 is fastened to the tank cover 12. Thereafter, the serration groove 56a of the extension spindle 56 is engaged with the serration groove of the levered spindle 20, so that the extension spindle 56
is fitted onto the lever-equipped spindle 20, and further the handle lever 24 is inserted so that the serration groove 32 of the handle lever 24 is engaged with the serration groove 56b of the extension spindle 56. Then, insert the screw 22 into the bolt insertion hole 3 of the handle lever.
6. Pass the extension spindle 56 through the female screw hole 20b
The handle lever 24 is firmly fixed to the lever-equipped spindle 20 by inserting the handle lever 24 into the spindle 20 and tightening it. Thereafter, the decorative cap 34 is attached to the handle lever 24, thereby completing the attachment.

Since the tank cover 12 is usually made of ceramic with high rigidity, the handle is directly attached to this highly rigid tank cover and does not wobble after being attached. Also,
As described above, the nut tightening operation for attaching the handle only requires one operation of tightening the cover nut 48, so the attachment operation is easy and quick.

As shown in FIG.
A pin 62 driven into the spindle portion of the lever fits into the keyway 60 and defines the rotation range of the lever-equipped handle 20. The pin 62 also has the function of fixing the lever portion 20a to the spindle portion.

Although the cutout 42a is provided in the above embodiment, a window-like opening through which a ring such as an E-ring can pass may be provided.

Further, in the above embodiment, the attachment portion 42 has a shape in which two parts of a circle are cut out in a chord shape, but it may be a polygon such as a triangle, a quadrangle, a pentagon, a hexagon, or an ellipse. Furthermore, a portion of the circular outer circumferential surface may be provided with protrusions or grooves. The opening provided in the wash water tank may have a non-perfect circular shape that can prevent the non-perfect circular mounting portion from rotating.

Although the above embodiment relates to a handle for application to a double-layer low tank, the handle of the present invention can also be attached to a single-layer low tank without a tank cover.

[Effect of idea]

As described above, according to the present invention, metal contact between the mounting portion and the lever-equipped spindle is prevented, and smooth handle operation without wear of the spindle is possible for a long period of time. Furthermore, in the present invention, the ring (for example, an E-ring) for preventing the resin sleeve from coming off, which is fitted into the spindle, can be attached very easily, so that the handle can be assembled easily.
