Description

[Detailed Description of the Invention] This invention relates to a water faucet opening/closing lever that can be easily attached to various types of faucets.

Conventionally, for example, Japanese Utility Model Application Publication No. 49-142168 discloses a water faucet opening/closing lever that is attached to a water faucet cock so that the faucet can be easily opened and closed with a weak force.

This item is made of an elastic plastic material, and has a total of three bent pieces at the tip and two locations on the left and right slightly behind the tip.

The planar shape of a water faucet is like an equilateral triangle with rounded vertices and slightly concave sides, resembling a three-leaf clover. To make this faucet open/close lever, first fit the bent piece at the tip of the lever into one concave part of the faucet, and then fit the left and right bent pieces into one protrusion so that they stick out from the left and right. It is attached to the cock.

By the way, although the planar shape of water faucets that are widely used in general households is basically as described above, the shape of each protrusion and the degree of indentation on each side vary in various ways. Not only do they come in a wide variety of planar shapes, but their outer diameters and thicknesses also vary widely.

There are also four-leaf clover-shaped ones.

In view of its structure, the water faucet opening/closing lever described in the above-mentioned publication can only be used by being attached to a faucet to which it can be attached exactly.

Therefore, the only way to make this product widely available to ordinary households is to produce a wide variety of products and put them on sale.

Although it is unthinkable that such a thing would be viable in business,
Even if a large variety of products were displayed at a retail store, buyers would have difficulty making a choice when purchasing, and in the end, very few products would sell.

Note that this cannot be attached to a four-leaf clover-shaped cock.

Further, the device disclosed in the above-mentioned publication is designed to be attached in the direction of one protrusion of the cock, that is, it can be attached only in three directions.

However, this water faucet opening/closing lever is not suitable for the situation where it is used.
If the device is not installed in the direction that is most convenient for the user depending on the user's preference, it may become inconvenient. It is something.

This invention eliminates the above-mentioned drawbacks of conventional water faucets, and can be installed on various water faucets commonly used in ordinary homes, and can be installed in any direction. The purpose of this invention is to provide a tap opening/closing lever.

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 is a partially sectional exploded perspective view showing one embodiment of this invention.

1 is the main body of the water faucet opening/closing lever according to this invention.

The main body 1 has a shape in which a lever rod 3 is attached to one side of a cylindrical body 2, and a donut-shaped upper plate 4 is attached to the upper surface of the cylindrical body 2.

The center of the upper plate 4 is slightly raised, and a circular hole 5 is formed inside the raised part.

The upper plate 4 has small circular holes 6, 6... at equal intervals.
I have 8 open.

Further, inside the cylindrical body 2, vertical protrusions 7 are provided at equal intervals.
There are eight 7.

A separate upper lid 8 is prepared, and the upper lid 8 has the shape of a lens-like disc that bulges toward the center, and holes 9, 9 are bored at two opposing locations in the upper lid 8.

The holes 9, 9 are formed in the upper plate 4 when the upper cover 8 is stacked on the main body 1.
The holes 6, 6, .

Next, a separate presser plate 10 is prepared, and the presser plate 10 has a disc shape that is sized to fit inside the cylindrical body 2 of the main body 1.

That is, the outer diameter of the presser plate 10 is equal to the ridge 7 provided on the cylindrical body 2.
, 7... are slightly smaller than the diameter of the circle connecting the inner peripheral ends of the circles.

A protrusion 11 is provided at one location on the outer periphery of the presser plate 10, and the protrusion 11 is the protrusion 7, 7... of the cylindrical body 2.
It is sized to fit perfectly into the space between.

Further, a circular hole 12 is formed in the center of the holding plate 10, and two opposing portions of the hole 12 are widened to form recesses 13, 13.

The hole 12 is smaller than the outside diameter of the water faucet cock and larger than the outside diameter of the valve stem, but the recesses 13, 13 are
This is for when passing the 0 to the bottom of the cock.

Internally female threaded holes 14 and 14 are bored at two opposing locations on the holding plate 10.

The holes 14° 14 are located at positions that coincide with any two of the opposing holes 6, 6, . It's open.

To attach the above to the water faucet, first
0 through the protruding part of the faucet's cock, and then move the presser plate 10 below the faucet and rotate it a little.The hole 12 is smaller in diameter than the faucet, so Kemono will no longer be able to move upwards.

Then, while covering the main body 1 on the presser plate 10, press the presser plate 1.
0 into the cylindrical body 2, the protrusion 11 of the presser plate 10 fits between two of the protrusions 7, 7, etc. provided on the cylindrical body 2, and the inside of the cylindrical body 2. At the same time that the presser plate 10 stops rotating, the two holes 14 of the presser plate 10,
14 is located at a position that coincides with any two opposing holes 6.degree.6 of the holes 6, 6, . . . made in the upper plate 2 of the main body 1.

Furthermore, stack the upper cover 8 on the upper plate 4, aligning the holes 9, 9 with the holes 14, 14 and the holes 6, 6, and insert the tightening screws 15, 15 through the holes 9, 9. 6, 6 and screwed into the hole 14.14, the work of attaching the water faucet opening/closing lever according to this invention to the faucet of the water faucet is completed, and the state shown in FIG. 2 is obtained.

When installed in this manner, the cock is tightened between the upper plate 4 and the holding plate 10 of the main body 1, as shown clearly in Figure 3, so when the lever rod 3 is rotated, the cock is tightened. They rotate as one.

Since the lever rod 3 is long, the cock can be opened and closed with very little force.

In addition, in what has been explained above, the upper lid 8 is not necessarily required functionally, and is mainly used for aesthetic purposes.

When the upper cover 8 is not used, the holes 5 may not be made in the upper plate 4.

Two or more lever rods 3 may be provided.

Furthermore, although the presser plate 10 is shown as having a female-threaded hole 14, the hole 14 may be simply a blank hole, and the tightening screw 15 may be tightened using a nut.

It is not necessary to provide the recess 13 either.

A portion of the presser plate 10 may be cut off to communicate with the hole 12, and the presser plate 10 may be fitted onto the valve stem from the communicating portion.

In the water faucet opening/closing lever according to this invention, first, the presser plate 10 is fitted below the tap of the faucet, and then the lever rod is adjusted to the angle most suitable for the user depending on the situation of the place of use, the user's preference, etc. 3. While making sure that the cylindrical body 2 of the main body 1 is
Put it on the cock.

Next, while leaving the main body 1 as it is, rotate the presser plate 10 left and right until the two holes 14 and 14 of the presser plate 10 are both in a position where they are out of the cock protrusion. Then, the presser plate 10 is fitted into the cylindrical body 2 while the protrusion 11 of the presser plate 10 is fitted between two of the protrusions 7, 7, . . . of the cylindrical body 2.

At this time, both of the holes 14, 14 of the presser plate 10 are removed from the position of the cock protrusion, and at the same time, both of those holes 14, 14 are removed from the holes 6, 6, . . . of the upper plate 4 of the main body 1. ...
They are in the same position as two of them, which are facing each other.

When the tightening screws 15 and 15 are inserted into the matching holes 6 and 14, respectively, and tightened, the faucet faucet is sandwiched between the upper plate 4 and the holding plate 10 of the main body 1, and the lever rod 3 has been attached to the cock, and the lever rod 3 has been attached at the optimum angle.

The reason why the tightening screws 15, 15 are tightened at two opposing positions is as follows.

It cannot be tightened even if it is tightened in one place.

It is necessary to tighten at least two places, but if it is tightened at three places, it cannot be used especially for a four-leaf clover-shaped cock.

If the screws are tightened in four or more places, more cocks will become unusable, and the installation process will become even more troublesome.

By tightening at two opposing locations, the installation process is easy, sufficient tightening force can be obtained after installation, and it can be installed on any type of cock.

There are eight holes 6, 6 at equal intervals on the upper plate 4 of the main body 1.
The reason for opening it is as follows.

Since the holding plate 10 has holes 14, 14 made at two opposing positions, it is necessary to make the holes 6 in the upper plate 4 while facing each other.

If two holes 6, 6 are used as a set of opposing holes 6, it becomes impossible to mount all types of cocks at arbitrary angles.

In particular, in the case of three-leaf clover-shaped cocks, a protrusion is often always formed at one of the two opposing positions.

The same holds true even when there are two sets of four holes 6.

Even when there are three sets of six holes 6, it is particularly inappropriate for a four-leaf clover-shaped cock.

As a result of collecting and testing various commercially available water faucets, we found that the upper plate 4 has 8 holes 6.6...
It has been found that it is possible to attach it to various cocks at any angle as long as it is spaced at 45° intervals.

No matter what the planar shape is, whether it's a three-leaf clover shape or a four-leaf clover shape, no matter what angle the lever rod 3 is at, the eight holes 6, 6... . . , one of the pairs in opposing positions will be in a position that is out of the way of the protrusion of the cock.

Therefore, the presser plate 10 is inserted into the pair of holes 6, 6 which have removed the protrusions.
If the holes 14 and 14 are aligned and installed, the lever rod 3 can be installed at any angle regardless of the type of cock.

It may be possible to make an even number of holes 6 (m or more), but having m or more holes 6 does not make it particularly convenient; on the other hand, if you increase the number of holes 6, Not only does the production process become more complicated and costs increase, but the strength also decreases.

Therefore, eight necessary and sufficient numbers can be said to be optimal.

Since the faucet opening/closing lever according to this invention is attached by tightening the faucet cock between the upper plate 4 and the holding plate 10 provided on the main body 1, it can be attached to faucets of various planar shapes. , it can be installed regardless of the outside diameter or thickness of the cock.

In addition, since the cock is installed by tightening between the upper plate 4 and the retaining plate 10, the contact area between the cock and the upper plate 4 and the retaining plate 10 becomes larger, increasing the tightening force and making it stronger. Can be installed on.

Therefore, even if the lever rod 3 is rotated, no slippage will occur between it and the cock.

The water faucet opening/closing lever of this invention not only allows you to open and close it with a weak force, but also allows you to operate it with the back of your hand, wrist, elbow, etc. when your hands are dirty or full, making it extremely convenient. be.
