Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a float valve hanging tool that connects an operating handle attached to a toilet flushing tank and a float valve with a chain. be.

[Conventional technology]

Typically, the float valve of a toilet flush tank is connected by a chain to a lever on an operating handle attached to the outside surface of the tank. When the operating handle is rotated, the float valve is pulled up via a chain connected to the lever, and flushing water is discharged from the opening of the toilet seat onto the inner surface of the toilet bowl, thereby cleaning the toilet bowl. As shown in FIGS. 6 and 7, the conventional chain and handle lever are connected using a connecting device 3, which is formed by bending both ends of a single wire rod and forming hooks 1 and 2. I was going. That is, one hook 1 is rotatably attached to the lever 5 of the operating handle 4, and the chain 6 is locked to the other hook 2. The locking between the chain 6 and the hook 2 is done using the hook 2.
Forcibly push the connecting pin 9 between the balls 8 through the narrow part 7 of the holder, position the connecting pin 9 in the insertion hole 10, and insert the balls 8, 8 before and after the connecting pin 9 that has been pushed through.
By preventing it from passing through the insertion hole 10,
A ball chain 6 is locked to the hook 2. In addition, in FIG. 6, 11 is a toilet bowl cleaning tank, 12 is a float valve for supplying cleaning water from the tank 11 to the toilet bowl side, and 13 is an overflow pipe.

[Problem that the invention attempts to solve]

However, in the conventional connection structure between the lever 5 and the chain 6, there was a problem that the tip 2a of the hook 2 protruded at an acute angle, and the connecting pin 9 became entangled with the hook 2. In other words, the entire length of the chain 6 is such that it still sag even when the float valve 12 is seated on the toilet seat, thereby reliably closing the toilet seat. Therefore, when the operating handle 4 is suddenly rotated, the chain 6 swings due to the reaction, and the connecting pin 9 located between the locking part of the hook 2 and the float valve 12 There was a drawback that it got caught in the narrow part 7 of the hook 2. Therefore, float valve 1
2 remains away from the valve seat, and flush water is continuously discharged into the toilet bowl. This problem with chains getting entangled is caused by the fact that the tank for flushing toilets is shipped as a finished product with all the attached parts assembled, so the chain 6 etc. swings a lot during shipping, causing the chain 6 and the hook to sway. 2 were sometimes intertwined.

Further, a sudden rotational operation of the operating handle 4,
If there is severe shaking during shipping, the connector 3 itself may come off the handle lever 5, making it impossible to operate the float valve 12. That is, there was a drawback that the toilet bowl could no longer be flushed.

Also, instead of the ball chain 6, a C-shaped chain (not shown)
Even when using , the same problem of entanglement still occurred. In the case of this C-shaped chain, the hook 2 and each chain were more easily engaged than in the case of the ball chain 6, and the problem of entanglement was more serious.

In addition, if the hook 2 and the chain 6 become entangled, the gap between the narrow portions 7 of the hook 2 will increase, and the connecting pin 9 will easily come off from this portion. Ta.

[Purpose of invention]

The present invention improves and eliminates the above-mentioned problems of the prior art, and aims to provide a float valve hanging tool that will never cause the chain to become entangled and will never cause the coupling device itself to come off. It is something.

[Means for solving problems]

The means of the present invention for solving the above problems are as follows:
A float valve hanging tool that connects the operating handle attached to the toilet flushing tank and the float valve chain has an insertion hole that is larger in diameter than the beads on the chain and smaller than the connecting pin between the beads. A ball chain connector having a narrow portion and an insertion hole having a larger diameter than the connecting pin and a smaller diameter than the ball is integrally connected to the handle lever of the operating handle.

[Effect]

As is clear from the embodiments shown in FIGS. 1 to 5, for the float valve hanging tools 22, 40, 42,
Wire rods 26, 2 that cause the chain 28 to become entangled
The ends of numbers 7, 43, etc. do not protrude to the outside.
For this reason, no matter how extreme the handle operation or shipping/
Even if there is severe shaking during transportation, the chain 28
and the hanging tools 22, 40, 42 never become entangled. Further, the connecting tool 34 is integrally connected to the handle lever 21 (including the case of integral molding), and the connecting tool 34 is connected to the handle lever 21.
There is no possibility that the float valve will become inoperable due to it coming off.

〔Example〕

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

1 to 3 show a hanging tool 22 according to a first embodiment of the present invention. As shown in the figure, this hanging tool 22 has a rectangular parallelepiped connecting tool 3 attached to one end of a cylindrical handle lever 21 in a plane perpendicular to the axis of the handle lever 21.
4 are integrally attached. Connector 34
, a rectangular through hole 23 is bored in a plan view, and a bottom wall surface 24 of the through hole 23 has a V
A letter-shaped notch groove 25 is bored parallel to the axis of the handle lever 21. Then, two wire rods 26, 2 are inserted from both ends sandwiching the V-shaped notch groove 25.
7 are erected. The wire rods 26 and 27 are set so that the distance between them is widened at the tip end and the bottom wall surface 24 side, respectively, and the distance between them is narrowed at the intermediate portion thereof.

At the tips of the wires 26 and 27, an insertion hole 30 having a diameter larger than the diameter of the ball 29 of the chain 28 is provided between the tip and the inner wall surface forming the through hole 23. is formed. Also, the wire rods 26 and 2
On the bottom wall surface 24 side of 7, an insertion hole 32 is formed by the V-shaped notch groove 25 and has a diameter smaller than the diameter of the ball of the ball chain 28 and larger than the wire diameter of the connecting pin 31. ing. Then, the insertion hole 30
For the intermediate portion that communicates with the insertion hole 32,
The narrow portion 33 is formed such that the distance between the wire rods 26 and 27 is smaller than the wire diameter of the connecting pin 31.

Thus, the hanging tool 22 configured in this way
As shown in FIG. 3, the handle lever 21 is rotatably inserted through a handle guide 36 attached to the side wall of the toilet cleaning tank 35, and the handle lever 21 is inserted into the handle guide 36 on the outside of the tank 35.
is connected and fixed to the operating handle 37 via a spring pin (not shown) or the like.

Next, the manner in which the hanging tool 22 of this first embodiment is used will be explained.

First, one end of the chain 28 is connected to the float valve by a predetermined method, and the other end is pushed into the insertion hole 30 of the connector 34 and passed through. And ball chain 28
The connecting pin 31 is connected to the narrow part 3 between the wire rods 26 and 27.
3, the chain 28 is forcibly pushed down at this position, and the interval between the narrow parts 33 is widened so that the connecting pin 31 passes through the narrow parts 33 and is located in the insertion hole 32. (See Figure 1). Insertion hole 3
2 is set to be larger than the wire diameter of the connecting pin 31 and smaller than the diameter of the ball 29, as described above. Moreover, the dimensions of the narrow portion 33 are set to be smaller than the wire diameter of the connecting pin 31. Therefore, the connecting pin 31 is in a loose relationship with the insertion hole 32, giving it some degree of freedom, and also preventing the connecting pin 31 from passing through the narrow portion 33 without permission and coming out to the insertion hole 30 side. Never.
Furthermore, it is impossible for the balls 29, 29 on the front and rear sides of the connecting pin 31 located in the insertion hole 32 to freely pass through the insertion hole 32, and for the ball chain 28 to come off.

In this state, when the operating handle 37 is rotated when flushing the toilet bowl, the handle guide 36
The handle lever 21 rotates integrally with the operating handle 37 inside. Therefore, the handle lever 21
The connecting tool 34 attached to the handle lever 21 rotates around the axis of the handle lever 21, and pulls the chain 28 upward. As a result, the float valve is pulled up via the chain 28, and the outlet communicating with the toilet side becomes open, so that the toilet cleaning tank 35
The flushing water flows out to the toilet bowl side, and the toilet bowl is flushed.

Therefore, in the above-mentioned handle operation, temporarily,
No matter how much the chain 28 shakes due to sudden rotation, the curvature of the middle part of the chain 28, which connects the balls 29, . The intermediate curved portion of the chain 28 never enters the through hole 23.
Therefore, it is impossible for the chain 28 to become entangled with the ends of the wires 26 and 27. Further, the swinging of the chain 28 due to the sudden handle operation is performed on the flat plate-like plane part of the connecting tool 34,
It simply slides on the plane, and the connector 34 has the function of restricting and inhibiting the swinging in one direction. Furthermore, since the connector 34 and the handle lever 21 are integrally connected, the connector 34 cannot come off the handle lever 21 even if the handle is suddenly operated.

FIG. 4 is a perspective view showing a hanging tool 40 according to a second embodiment of the present invention. In this second embodiment, an insertion hole 30, a narrow portion 33, and an insertion hole 32 are formed directly in a rectangular parallelepiped-shaped connector 34 made of synthetic resin. And the connecting pin 31 (see Figure 3)
In order to force the connection pin 31 to pass through the narrow part 33, the narrow part 33 must have sufficient elasticity for the connecting pin 31 to pass through.
1,41. The other configurations and effects are exactly the same as in the first embodiment.

FIG. 5 is a partial perspective view showing a hanging tool 42 according to a third embodiment of the present invention. In this embodiment, a single wire 43 is bent to form the insertion hole 30, the narrow part 33, and the insertion hole 32, and the end of the wire is buried in the lower end surface of the rectangular parallelepiped connector 34. ing. Therefore, even in this case, the wire ends, hooks, etc. that cause the chain 28 to get caught do not protrude within the swinging range of the chain 28, so it is impossible for the chain 28 to become entangled. The functions of the insertion hole 30, the narrow portion 33, the insertion hole 32, etc. are the same as in the first and second embodiments, and will not be described here.

By the way, the present invention is not limited to the above-mentioned embodiments, and can be modified as appropriate. For example, the shape of the connector 34 may be cylindrical instead of rectangular.

[Effect of idea]

As explained above, in the case of the present invention, there is no wire end or hook in the chain connecting device, so the chain does not swing due to sudden handle operations or during transportation. Even if it got hot, there was no entanglement with the chain. Therefore, there is no accident such as the float valve remaining in a raised state, resulting in poor water stoppage. Furthermore, the connector and the handle lever are integrally attached, and there are no accidents such as the connector coming off the handle lever and making it impossible to operate the float valve.
