Description

[Detailed Description of the Invention] This invention relates to a faucet operating device, and particularly to an operating device that can be operated with a foot.

Water faucets are generally operated by hand,
Due to hygiene requirements and other considerations, devices with foot-adjustable flow rates have been proposed and implemented.

However, conventional foot-operated devices basically have to have a special configuration from the stage of equipment construction, and cannot be easily installed in existing water supply systems.

Therefore, the main objective of the invention is to provide a foot-operated faucet operating device, which can be easily installed, especially in existing equipment.

Simply put, this invention is a faucet operating device in which a lever for a flow path opening/closing valve attached to a faucet at hand is rotated by the foot.

The lever is always urged by the spring to rotate in the direction of closing the flow path opening/closing valve.

Further, one end of a wire for pulling the lever against the force of the spring is connected to the lever.

The other end of this wire is connected to a displacement member adapted to be displaced by direct foot manipulation.

Therefore, by operating the displacement member with the foot to displace it and thereby pulling the wire, the lever rotates in the direction to open the flow path opening/closing valve.

In this way, water is removed from the mouth.

The above objects and other objects and features of the present invention will become more apparent from the following detailed description with reference to the drawings.

FIG. 1 is an illustrative view showing the main parts of an embodiment of this invention.

In configuration, this embodiment has as its main parts:
It includes a faucet device 100, an operating device 200, and a connecting wire 300.

The faucet device 100 includes a pipe 102 having a mounting portion 101 formed at one end thereof for attaching the faucet device 100 to a pipe (not shown).

This mounting portion 101 typically includes, for example, its piping (
(not shown) is formed to engage with a screw formed therein.

A faucet 111 is connected to the tip of the pipe 102 by a connecting fitting 110, and water is configured to come out from the tip of the faucet 111.

A cock 105 is inserted in the middle of the pipe 102, and this cock 105 includes a passage opening/closing valve (not shown) therein. Opening/closing controlled.

For example, this cock lever 106 can be connected to arrow A shown in FIG.
The valve included in the cock 105 is closed when the cock 105 is tilted in the direction of the arrow B, and the valve inside the cock 105 is opened when the cock 105 is tilted approximately 90 degrees in the direction of the arrow B.

The pipe 102 further includes this cock 105.
Supports 103 and 108 are attached to both sides of the frame.

A spring 107 is stretched between a locking portion 109 formed at the tip of the support 108 and a locking portion 106a at the tip of the cock lever 106.

Therefore, this spring 107 constantly constrains or biases the cock lever 106 in the direction of arrow A.

Furthermore, one end of a flexible sleeve 301 that constitutes the connecting wire 300 is fixed to a locking portion 104 formed at the tip of the support 103.

One end 303 of the wire 302 is displaceably housed within the flexible sleeve 301.
is locked to a locking portion 106a of the cock lever 106.

The coupling wire 300, as shown in particular in FIG. 3, includes a series of wires 302 and a flexible sleeve 301 surrounding the wires 302.

Both flexible sleeve 301 and wire 302 can be bent into any shape.

Preferably, one end 303 and the other end 304 of the wire 302 are respectively connected to the other portions of the wire 302.
It is sufficient if it is made of a steel material having greater rigidity.

If this is done, there will be less deformation of the wire in this part and it will be more effective.

The other end 304 of the wire 302 is connected to the operating section 200.

The operation unit 200 includes a housing 201, as shown in FIG.

A displacement member 202 is provided approximately in the center of the housing 201, and is configured to be displaced by direct foot operation.

Specifically, the displacement member 202 is an operating lever rotatably supported by a fulcrum 202a.

The other end of the flexible sleeve 301 included in the connecting wire 300 passes through the housing 201.
It is fixed in the vicinity of the operating lever 202 by a support 204 formed inside the 01.

The other end 304 of the wire is connected to the tip of the operating lever 202.

The tip of the operating lever 202 is further configured to be able to come into sliding contact with the flat surface of a leaf spring 203 housed within the housing.

Such an operation unit 200 may be installed on the floor 400, for example.
Fixed.

The operation or operation of the above configuration will be explained below with reference to FIG. 4.

In the state shown in FIG. 4a, the tip of the operating lever 202 is at its maximum point in the direction of arrow C.

This state is stably maintained by the leaf spring 203 that comes into contact with the tip of the operating lever 202.

In the state shown in FIG. 4a, the cock lever 106 of the faucet device shown in FIG. 1 is at a position that closes the flow path opening/closing valve connected thereto, for example, at the position indicated by the two-dot chain line 106' in FIG.

Therefore, in this state, no water flows out from the faucet 111.

Next, as shown in FIG. 4, when the rear end of the operating lever 202 is displaced in the direction of the arrow C, the tip of the operating lever 202 is also displaced in the direction of the arrow C accordingly.

At this time, the tip of the operating lever 202 is displaced while being in contact with the leaf spring 203.

In the state shown in FIG. 4, the deflection of the leaf spring 203 is at its maximum.

In the state shown in FIG. 4, the faucet device 100 shown in FIG.
The cock lever 106 is in the position shown in FIG.

Therefore, at this time, the valve included in the cock 105 connected to the cock lever 106 is in its approximately half-open state.

Furthermore, the rear end of the operating lever 202 is displaced in the direction of arrow C.

Then, as shown in FIG. 4C, the operating lever 202
The tip of is displaced to the maximum position in the direction of the arrow.

This state is also stably maintained by the leaf spring 203.

In the state shown in FIG. 4C, the other end 304 of the wire 302 is pulled in the direction of the arrow in accordance with the displacement of the tip of the operating lever 202, and therefore the cock lever 106 is moved along the chain line 106'' in FIG. Displaced to the position of

Therefore, the cock 1 connected to the cock lever 106
The valve included in 05 reaches its maximum opening degree in the state shown in FIG. 4C.

In this way, especially the states shown in FIGS. 4A and 4C are stably maintained by the action of the leaf spring 203.

If the operation lever 202 is to be displaced from the state shown in FIG. 4C to the state shown in FIG. The wire end 303 displaces the cock lever 106 in the direction of arrow A shown in FIG.

At the same time, the action of the spring 107 makes the displacement in the direction of arrow A more reliable.

FIG. 5 is an illustrative view showing a preferred embodiment of this invention.

In the embodiment shown in FIG. 5, the faucet device 10G is attached above the sink 500, and the operating device 200 is fixed to the front or side of the sink.

According to the embodiment shown in FIG. 5, even when water from the faucet device 100 is used in the sink 500, the operating device 2
The water flow interruption can be controlled only by operating the operating lever 202 of 00.

Therefore, by operating the control lever 202 after bringing the items to be washed to the sink 501, water can be effectively saved.

In addition, since it can be operated by foot, it is very hygienic, even in places where hygienic requirements are strong, such as in restaurants, because there is no need to operate it by hand.

Moreover, since the flow can be interrupted by operating the foot, it will be possible to perform laundry tasks efficiently at restaurants, for example.

Moreover, since the faucet device 100 is configured to be detachable from existing piping, if the operating device 200 and connection wire 300 are prepared, it can be easily installed to the existing water supply equipment, and it can be easily attached to the existing water supply equipment. There is no need for large-scale equipment construction.

Furthermore, the only means for connecting the faucet device 100 and the operating device 200 is the connecting wire 300.

Therefore, even if the distance between the devices 100 and 200 becomes longer or shorter, for example by changing the height of the sink 500, it is only necessary to change the length of the connecting wire 300. There is a large degree of freedom in the above-mentioned installation.

FIG. 6 is an illustrative view showing another example of how the operating device 200 is attached.

This example is attached to a vertical wall 600, whereas the example of FIG. 2 is attached to a floor 400.

It is clear that even if this is done, the operability will not be impaired in any way.

FIG. 7 is an illustrative view showing the main parts of another embodiment of this invention.

This embodiment is similar to the previously described embodiment except for the following points.

That is, in this embodiment, the operating device 700 is different from the previous operating device 200.

More specifically, as shown in FIG. 8, the operating device 700 includes a housing 701 and a pedal 704 that is a displacement member fitted into the housing 701.

This pedal 704 is provided so as to be movable in the direction of arrow E and the direction of arrow F along a guide 702 around the opening formed in the housing 701.

A support 705 is integrally formed on this pedal 704 so that it can be displaced, and this support 705
The other end 304 of the wire is connected to the tip of the wire.

That is, the flexible sleeve 301
It is fixed by a support 703 formed inside the housing 701 passing through the guide 702 and the pedal 704, and the other end 304 of the wire extending from the tip thereof is connected to the support 705.

The pedal 704 has, for example, a cylindrical shape, and a spring 706 is inserted between the inside of the cylindrical portion and the bottom surface of the housing 701.

Therefore, the spring 706 is constantly in contact with the pedal 704
It acts to bias or push up in the direction of arrow E.

In such a configuration, the pedal 704 is now connected to the spring 7
If you step in the direction of arrow F against the biasing force of 06,
Together with this pedal 704, the tip of the support 705 moves downward, that is, in the direction of arrow F, and the tip of the other end 304 of the wire connected thereto also moves downward.

Therefore, the wire 302 pulls the cock lever 106 in the direction of arrow B shown in FIG.

Therefore, the flow path opening/closing valve (not shown) of the cock 105 connected to the cock lever 106 opens, and the faucet 111
Water flows out from.

Then, when the pedal 704 is released, the spring 70
6, the pedal 704 and therefore the support 705 are pushed up in the direction of arrow F, and the other end of the wire 304 returns to the state shown in FIG.

Therefore, along with the action of the spring 107, the cock lever 1
06 will be returned to the closed position again.

In this embodiment, unlike the operating device 200 shown in the embodiments such as FIGS. 1 and 2, a mechanism for stably maintaining the displacement state of the pedal 704 is not provided. Pedal 70 while you want water to flow out.
Step 4 must be continued.

However, unlike the previous embodiment, this embodiment:
It will be possible to more delicately adjust the water flow rate.

Note that in the embodiments shown in FIGS. 7 and 8 described above, the shape and structure of the pedal 704 are not limited to those shown in the figures.

In other words, assuming that the pedal is a flat plate, one end of the pedal is fixedly held on the floor, the other end is pushed up or biased by a spring or the like so that it is positioned above the floor, and a wire is attached to the other end. It would be easy to imagine a structure in which the other ends are connected.

In this case, a spring or the like for keeping the pedal pressed up may have a relatively weak biasing force, and in the extreme, it may not be necessary at all.

FIG. 9 is an illustrative view of the main parts showing another example of the operating section that can be used in this invention.

The operating section 800 includes a lower frame 801 and a frame 802 rising from the tip of the lower frame 801 at a predetermined angle.

At the rear end of this frame 801, the tip of a pedal or treadle 803, which is a displacement member, is connected to an arrow G by a shaft 804.
Alternatively, it is supported so that it can be displaced in the H direction.

Although not shown in FIG. 9, a coil spring is disposed below the tread plate 803.
3 is constantly biased in the direction of arrow I4.

A stepped portion 805 is formed at the tip of the footboard 803.

The other end 304 of the connecting wire is fixed to the tip side end of the footboard 803.

Therefore, by stepping on this step board 803 in the direction of arrow G, the other end 304 of this wire, and therefore the wire 302, is pulled downward.

Thereby, for example, the cock lever 10 shown in FIG.
6 moves in the direction of arrow B (Fig. 1), thereby faucet 1
Water comes out from 11 (Figure 1).

It should be noted that a locking plate 807 is attached to the frame 802, for example, by hinges 808, 808, so as to be rotatable in the arrow {circle around (2)} or J direction.

The length of this locking plate 807 is selected such that the tip of this locking plate 807 engages with the step 805 when the footboard 803 is fully depressed in the direction of arrow G. .

In such a configuration, the following shows the first OA diagram or the first
The operation of this operation unit 800 will be explained with reference to diagram 0C.

Referring to FIG. 10A, this FIG. 10A shows a state in which water is operated for a short period of time.

Note that a coil spring 809 is provided below the footboard 803.

If you want to temporarily release water, as shown in FIG. 10A, you can push the locking plate 807 in the direction of arrow 1 with your shoes, for example, and then step on the tread plate 803 in the direction of arrow G. .

Then, water will come out of the faucet (Figure 1).

Then, when the depression in the direction of arrow G is released, the footboard 803 is returned in the direction of arrow H by the action of the coil spring 809.

That's why the water stops. Next, referring to FIG. 10B, the operation for dispensing water for a long time will be described.

In this case, the footplate 803 is depressed almost fully in the direction of arrow G using the shoe.

At this time, the locking plate 807 is not pushed in the direction of the arrow (■) depending on the shoe.

Therefore, when the footboard 803 is depressed, the locking plate 807
is returned in the direction of arrow J by its own weight or by a spring (not shown).

Then, the tip of this locking plate 807 engages with the step portion 805 described above.

Therefore, even if you release the pedal, the arrow H on the tread plate 803
The return by the spring 809 in the direction is prevented by the action of the locking plate 807 and the stepped portion 805.

Therefore, in the state shown in FIG. 10B, water continues to flow from the faucet.

If you want to stop the water from the state shown in Fig. 10B, perform the operation as shown in Fig. 10C.

That is, the user pushes the locking plate 807 in the direction of arrow 1 with the tip of the shoe.

Then, the engagement between the tip of the locking plate 807 and the stepped portion 805 is released.

Then, when the foot plate 803 is released, the spring 80
9, this step board 803 is displaced in the direction of arrow H.

The water will stop accordingly.

As described above, according to this invention, an operating device that can be operated with the foot can be obtained with a relatively simple configuration.

Moreover, such an operating device can be easily installed by replacing the faucet device with the existing one.
It would be very effective.
