Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handle and its mounting structure used in a double-layer low tank in which a wash water tank is surrounded by a tank cover.

[Conventional technology] A low tank is one of the tanks used to supply flush water to Western-style toilets.The low tank is a system in which the tank body (flush water tank) for storing flush water is surrounded by a tank cover. A double-layer low tank is 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.

In Figure 6, the handle is the wash water tank 1.

A spindle with lever 20 is rotatably held in
It mainly consists of a handle lever 24 which is fixed with a handle lever 24. A nut 26 is screwed into the mounting portion 18 from the front side thereof. The mounting part 18 is provided with a flange part 18a for holding the edge of the opening 14 between the nut 26 and the mounting part 18a by tightening the nut 26.
is fixed to the wash water tank 10. Further, the lever-equipped spindle 20 has a lever portion 20a,
A chain hook 28 is attached to the tip of this lever portion 20a. This chain hook 28
A chain is attached to this, and the chain lifts a valve provided at the bottom of the low tank, so that the wash water in the wash water tank 10 is flushed out into a toilet bowl (not shown).

The tip of the lever-equipped spindle 20 is a serration shaft 30, and the handle lever 24 is provided with a serration groove 32 that engages with the serration shaft 30. Handle lever 24
This serration groove 32 is connected to the serration shaft 3.
It is inserted into the opening 16 from the outer surface side of the tank cover 12 so as to be inserted into the handle lever 2.
A screw 22 that is screwed in from the front side of the serration shaft 30 is screwed into a female threaded hole of the serration shaft 30, whereby the handle lever 24 is connected to the lever-equipped spindle 20. Reference numeral 34 is a decorative cap that closes the insertion hole 36 of the screw 22. Further, reference numeral 38 indicates the opening 16.
A nut 40, which is a decorative nut inserted into the tank cover 12, is screwed from the back side of the tank cover 12, thereby covering the opening 16 of the tank cover 12.

[Problems to be Solved by the Invention] The conventional handle mounting structure described above has a problem in that the handle tends to wobble after mounting, and the mounting work tends to be complicated.

That is, the wash water tank 10 is usually made of low-rigidity synthetic resin, and when a strong force is applied to the handle lever 24, the entire handle tends to wobble. In addition, in the above mounting structure, the handle is attached to the cleaning water tank 1.
Since the length from this attachment part to the handle lever 24 is large, the amplitude of this wobble tends to be large.

Furthermore, when attaching the handle, two nut tightening operations are required: one for screwing in the nut 26 and one for screwing in the nut 40. As a result, the assembly work was complicated and took a long time.

[Means for solving the problem] 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 mounting part is mounted by sandwiching the opening edge with a cover nut that is screwed onto the mounting part from the opposite side of the side wall opening. can be firmly attached to the low tank (tank cover). Therefore, this mounting portion has a non-perfect circular cross-sectional shape.

In the handle mounting structure of the present invention, the mounting portion into which the lever-equipped spindle is inserted is held at the opening edge of the tank cover, and the cover nut is screwed onto the mounting portion from the outside of the tank cover and tightened. It is fixed to the cover, and the handle lever is fixed to the spindle.

[Function] According to the present invention, the handle can be attached to the low tank extremely firmly, easily and quickly.

That is, when attaching the handle of the present invention to a low tank, first insert the mounting portion into which the lever-equipped spindle is inserted into the side wall opening of the wash water tank, and then cover the wash water tank with the tank cover. Next, insert a cover nut into the opening of the tank cover from the outside of the tank cover and rotate it. As a result, the screw of the cover nut engages with the mounting part, and the mounting part is gradually drawn toward you.
In the pair, the flange of the mounting part and the flange of the cover nut sandwich the tank cover opening edge, and the mounting part is firmly fixed to the tank cover. Note that the wash water cover has a non-perfect circular opening that can prevent the mounting portion from rotating, so that the mounting portion will not rotate together even when the cover nut is turned.

Since the tank cover is made of highly rigid ceramic, the handle will not wobble after installation. Further, the nut tightening work only needs to be done once, and the installation work is easy and quick.

[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 same essential parts seen from the opposite direction, Fig. 3 is a longitudinal sectional view showing the installed state, and Fig. 4 is a FIG. 4 is a sectional view taken along the - line in FIG. 3;

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 portion of the spindle with lever 20 is inserted into the mounting portion 42 as described above, and the resin sleeve 52 is inserted into this spindle portion.
The tip of this resin sleeve 52 is inserted between the inner circumferential surface of the mounting portion 42 and the outer circumferential surface of the spindle portion to prevent direct contact (metal touch) between the mounting portion 42 and the outer circumferential surface of the lever-equipped spindle 20. . Note that this resin sleeve 52 is stopped by an E-ring 54 inserted into the spindle with a lever.

The tip of the spindle with lever 20 is a serration shaft 30, and the serration groove 56a of the extension spindle 56 is connected to this serration shaft 30.
can be engaged with. A serration groove 56b is provided on the other end side of the extension spindle 56, and this serration groove 56b 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. Reference numeral 34 is a makeup cap, and 58 is a packing.

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 has a non-perfect circular opening with two parallel cutouts in the chord direction. 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 completing the installation. 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 enters into this keyway 60 and defines the rotation range of the lever-equipped spindle 20. The pin 62 also has the function of fixing the lever portion 20a to the spindle portion.

In the above embodiment, the mounting portion 42 has a shape in which two parts of a circle are cut out in a chord shape, but in the present invention, in short, when the cover nut 48 is tightened, the mounting portion 42 can rotate together with the cover nut 48. For example, it may be a polygon such as a triangle, quadrangle, pentagon, or 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.

In this case, as in the above embodiment, the shape of the mounting part and the opening shape of the cleaning water tank may be similar shapes, or they may have dissimilar shapes, for example, the mounting part may be square and the opening of the cleaning water tank may be triangular. .

[Effects of the Invention] As described above, according to the present invention, the handle can be attached to the low tank extremely easily and quickly, and the handle does not wobble after being attached.
