Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cover of a low tank for storing flush water for a toilet bowl.

[Prior Art] A low tank is normally provided with a float valve therein, and is configured to supply flush water to a toilet by pulling up the float valve.

The outside of such a raw tank is usually surrounded by a cover made of synthetic resin.

[Problems to be solved by the invention] When the raw tank is surrounded by a conventional cover,
When inspecting and repairing equipment such as ball taps and float valves in the low tank, it is necessary to remove the entire cover,
It takes a lot of work. Therefore, it is conceivable that the cover is divided into two, one half is fixed to the toilet, and the other half is detachable. However, in this case, there is a problem that water easily invades from the joints (particularly the joints extending in the horizontal direction) of the two half halves.

[Means for Solving the Problems] A cover of a low tank of the present invention is a cover surrounding a low tank for storing flush water in a toilet bowl, the cover including a rear half body surrounding a rear portion of the low tank and a front of the low tank. And a front half-part that surrounds the rear half-part, and the front half-part has a lid-shaped part that covers the rear half-part, and the lower end surface of the lid-shaped part is above the rear half-part. It overlaps with the end face, and one of the upper end face of the rear half body and the lower end face of the lid-like portion is provided with a convex strip and the other is provided with a concave strip, and the convex strip fits into the concave strip. And a handle for a low tank is attached to the rear half body.

[Operation] In the cover of the present invention, the rear half body can be fixedly attached to the toilet bowl, and the front half body body can be detachably attached to the toilet bowl. Since the handle for the low tank is attached to the rear half-split body, only the front half-split body can be attached / detached to easily inspect and repair the low tank and various devices.

In the cover of the present invention, the convex strip is provided on one of the lower end surface of the lid-shaped portion and the upper end surface of the rear half body and the concave strip is provided on the other, and the concave strip and the convex strip are fitted to each other. Since they are matched, water can be surely prevented from entering the inside of the cover. In addition, the connection strength between the two halves is also improved.

[Embodiment] FIG. 1 is a perspective view showing an assembled state of a cover according to an embodiment,
2 (a) is an explanatory view of assembly of the cover, FIG. 2 (b) is a sectional perspective view of a portion B of FIG. 2 (a), FIG. 3 is a side view of the cover, and FIG. 4 is a front view of the cover. 5 and 5 are longitudinal sectional views showing the engagement relationship between the rear cover (rear half-divided body) and the lid-shaped portion.

The low tank 1 is for supplying water to a Western style toilet (not shown), and is installed on a base plate 2 fixed to the rear upper surface of the Western style toilet.

The cover 3 that surrounds the raw tank 1 includes a rear cover (half-split body) 4 and a front cover (half-split body) 5. The rear cover 4 has a substantially U-shaped plan view shape, and a lower end edge thereof is screwed to the base plate 2. A handle 12 for a low tank is attached to the side surface of the rear cover 4.

A reinforcing member 6 is installed between the upper end portions of both side surface portions 4a and 4b of the rear cover 4. The reinforcing member 6 is formed by elongating both ends of a metal material such as a long strip of metal such as stainless steel in a downward direction to form standing piece portions 6a and 6b. Each standing piece
6a and 6b are fixedly attached to the side surfaces 4a and 4b of the rear cover 4 with decorative bolts 7.

That is, openings 8 and 9 are formed in the standing piece portions 6a and 6b and the side surface portions 4a and 4b, respectively, and a bolt 7 is inserted into the openings 8 and 9, and a nut (not shown) is tightened to fasten the two. Has been done. By providing such a reinforcing member 6, the strength and rigidity of the rear cover 4 can be increased. In the present embodiment, the reinforcing member 6 wraps around the upper side of the raw tank 1, but it may also wrap around the front surface or the rear surface of the raw tank 1.

In the present embodiment, the front cover 5 is integrally provided with a hand-washing pot portion 10 as a lid-like portion which covers the upper side of the rear cover 4. Reference numeral 11 indicates a water discharge fitting.

As shown in FIG. 2 (b) and FIG.
The lower end surface 20 of the 10 is provided with a concave stripe portion 13, and the upper end surface 21 of the rear cover 4 is provided with a convex stripe portion 14. Such concave line 13 and convex line
By fitting the two together, the watertightness between the end faces 20 and 21 is improved, and even if water is transmitted from the handwash bowl 10 and falls, it does not enter the inside of the cover 3. Further, the connection strength between the front cover 5 and the rear cover 4 is also high.

In the cover 3 configured as described above, only the front cover 5 is removed and the low tank 1, the ball tap, the float valve, the hot water washing device, and the heated toilet seat device (not shown).
It is arranged in the empty space S portion immediately above the base plate 2 in FIG. ) Can be easily inspected and repaired.

It is also possible to provide a convex strip on the lower end surface 20 of the hand-washing pot portion 10 and provide a concave strip on the upper end surface 21 of the rear cover 4. These ridges and ridges may be provided in steps as shown in FIG.

In the present invention, in addition to the convex stripes and the concave stripes, pin-shaped projections and concave holes may be further provided.

In the above-mentioned embodiment, the hand-washing pot part 10 is provided on the front cover 5, but instead of the hand-washing pot part 10, as shown in FIG.
A front cover 5A having 15 may be used.

[Effect] As described above, the cover of the low tank of the present invention can be inspected and repaired by attaching / detaching only the front half-split body to the low tank, the ball tap, the float valve, and various devices such as the hot water washing device and the heating toilet seat device. Very easy to do.
