Benefits of technology

The present invention provides a toilet bowl flushing water tank device that prevents the wasteful discharge of flushing water by allowing anyone to change the position of the float. The device includes a flushing water tank for storing flushing water, a discharge valve for opening / closing the discharge outlet, a manipulation portion for performing a pull-up operation of the discharge valve, a connection member for connecting the manipulation portion and the discharge valve, and a float mounted on the connection member in a state that the connection member is allowed to pass through the float. The connection member includes an upper engaging portion and a lower engaging portion for restricting the movable range of the float on the connection member, and at least the lower engaging portion includes a lower irreversible engaging jig having physical irreversibility. This prevents the removal of the lower engaging portion from the connection member unless broken. The upper engaging portion includes an upper irreversible engaging jig and / or an upper reversible engaging jig, and the lower engaging portion includes a lower irreversible engaging jig and / or a lower reversible engaging jig. This prevents the wasteful discharge of flushing water in advance.

Problems solved by technology

However, the toilet bowl flushing water tank device described in patent document 1 allows anybody to simply change the position of the float and hence, for example, when the float is lowered and arranged at a lower position, the supply quantity of flushing water is excessively increased thus leading to the wasteful discharge of flushing water.

first embodiment

[0029]According to the above-mentioned constitution, as shown in FIG. 2A to FIG. 2E, in the toilet bowl flushing water tank device 1 according to the first embodiment 1, an upper engaging portion 4 and a lower engaging portion 5 for restricting a movable range of the float 16 are mounted on the connection member 15 formed of a ball chain. At least the lower engaging portion 5 includes a lower irreversible engaging jig 50 having physical irreversibility which prevents the removal of the lower engaging portion 5 from the connection member 15 unless broken.

[0030]In this embodiment, it is sufficient that the lower engaging portion 5 includes the lower irreversible engaging jig 50, and the upper engaging portion 4 may be formed of any engaging jig.

[0031]For example, the upper engaging portion 4 may be configured to include either one of an upper irreversible engaging jig 40 formed of the same member as the lower irreversible engaging jig 50 and having physical irreversibility which preve...

second embodiment

[0056]Next, a toilet bowl flushing water tank device according to a second embodiment of the present invention is explained in conjunction with FIG. 4A to FIG. 4C.

[0057]FIG. 4A to FIG. 4C are schematic explanatory views showing an arrangement state of a float in the toilet bowl flushing water tank device according to a second embodiment. In the same manner as the first embodiment explained above, a float 16 according to this embodiment is configured such that a center hole portion 16a which constitutes a recessed portion for allowing a connection member 15 to pass therethrough is formed in a center portion of the float 16.

[0058]Here, this embodiment differs from the embodiment described above with respect to a point that a lower irreversible engaging jig 50 and / or an upper irreversible engaging jig 40 are / is accommodated or arranged in such a center hole portion 16a.

[0059]That is, as shown in FIG. 4A to FIG. 4C, the float 16 is formed of a circular disc portion 16d in which a throu...

Abstract

The present invention provides a toilet bowl flushing water tank device which can prevent the easy increase of a supply quantity of flushing water to a toilet bowl exceeding a predetermined quantity. The present invention provides a toilet bowl flushing water tank device which includes: a flushing water tank for storing flushing water to be supplied to a toilet bowl and forming a discharge outlet which communicates with the toilet bowl in a bottom portion thereof; a discharge valve for opening / closing the discharge outlet; a manipulation portion for performing a pull-up operation of the discharge valves a connection member for connecting the manipulation portion and the discharge valve; and a float mounted on the connection member in a state that the connection member is allowed to pass through the float and generating buoyancy for maintaining a valve-open state of the discharge valve in a state that the float is immersed in the flushing water, wherein the connection member includes an upper engaging portion and a lower engaging portion for restricting a movable range of the float on the connection member, and at least the lower engaging portion includes a lower irreversible engaging jig having physical irreversibility which prevents the removal of the lower engaging portion from the connection member unless the lower irreversible engaging jig is broken.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a toilet bowl flushing water tank device having a float generating buoyancy for maintaining a valve-open state of a discharge valve in a state that the float is immersed in flushing water.[0003]2. Background Art[0004]Conventionally, there has been known a toilet bowl flushing water tank device which includes a flushing water tank for storing flushing water to be supplied to a toilet bowl, a discharge outlet communicating with a flushing water supply passage which is formed in a bottom portion of the flushing water tank and communicates with the toilet bowl, a discharge valve for opening / closing the discharge outlet, a manipulation portion for performing a pull-up operation of the discharge valve, a connection member for connecting the manipulation portion and the discharge valve, and a float mounted on the connection member in a state that the connection member is allowed to pass through...
