Assume that In such a case, when the handle portion 32 is returned from another state to the original state, as shown in FIGS. In some cases, the gap may enter the gap between the upper surface 12 and the lower surface of the handle portion 32 and be pinched. Therefore, there is room for improving this type of hydrant in terms of safety.

[0004] If the handle 30 is disposed sufficiently separated from the water faucet main body 10, the finger 80 will not be pinched and safety will be ensured. However, according to this aspect, the sense of unity between the hydrant main body 10 and the handle 30 is impaired, and it becomes difficult to secure the design of the entire hydrant.

The present invention has been made in view of such circumstances, and an object of the present invention is to ensure the design of the entire faucet and the safety thereof.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, first, a means adopted by the invention of claim 1 is that a means having a hydrant body and a handle portion is provided so as to protrude from the hydrant body. And a handle that is rotated and operated, wherein a finger of a hand that operates the handle is caught in a gap between the hydrant body and the grip formed by the rotating operation of the handle. A water faucet, wherein a preventing means for preventing the water faucet is provided on at least one of the handle and the water faucet body. "
It is.

According to the present invention, the prevention means can prevent the fingers of the hand operating the handle from being pinched, thereby ensuring safety. In the hydrant of the present invention, the safety can be ensured without sufficiently separating the handle and the hydrant main body. Performance can be improved.

In the present invention, the specific form of the "preventing means" is not particularly limited.
Various forms such as the "wide-angle forming section" in the invention of the present invention can be adopted.

Next, the means adopted by the invention of claim 2 is:
The water faucet according to claim 1, wherein the prevention means is a protrusion preventing part that interferes with a finger and makes it difficult for the finger to protrude toward the water faucet body.

According to the present invention, the finger for operating the handle is less likely to protrude from the handle to the hydrant body by the protrusion preventing portion. And it is difficult to intrude into the gap, thereby preventing pinching of the finger.

Here, various forms of the "protrusion preventing portion" in the present invention can be selected. For example, in a mode in which a gap is formed between the lower surface of the handle portion and the upper surface of the water faucet main body by operating the handle portion upward, a substantially wall-like shape extending below the lower surface of the handle portion is provided. And a substantially wall-shaped one extending above the upper surface of the water tap main body. Further, in a mode in which a gap is formed between the upper surface of the handle portion and the lower surface of the water faucet main body by operating the handle portion downward, a substantially wall-like shape extending above the upper surface of the handle portion. And a substantially wall-shaped one extending downward from the lower surface of the water faucet body. Further, the form of the protrusion preventing portion is not limited to the one extending substantially in the shape of a wall, and various other types such as those extending from the entire handle portion can be adopted.

Next, means adopted by the invention of claim 3 is:
The said prevention means is a wide-angle formation part which makes the angle of the said gap 45 degree or more in the state in which a finger can enter the said gap, The Claim 1 or Claim 2 characterized by the above-mentioned. Hydrant ".

[0013] The angle of the gap between the hydrant body and the handle is 45 °.
If a finger is present in this gap when the degree is less than the degree, the finger is pinched. This will be described in detail in “Embodiments of the Invention”. In response to such a phenomenon, according to the present invention, even if the finger can enter the gap, the angle of the gap is set to 45 degrees or more by the wide-angle forming portion, and thus the finger is prevented from being pinched. .

Here, "the state in which a finger can enter the gap" refers to a state in which the center axis of the cylinder can be present in the gap between the water faucet main body and the gripping part when the finger is assumed to be a simple cylinder. Show. The diameter of the cylinder may be set in consideration of the size of the finger. For example, the thumb of an adult man is 15 ~
The other finger of an adult man and the thumb of an adult woman have a diameter of about 10 to 15 mm, and the other finger of an adult woman and the finger of a child have a diameter of about 5 to 10 mm. Therefore, diameter 20mm
Even if the cylinder center of the degree can exist in the gap,
The wide-angle forming section is preferably set so that the angle of the gap is 45 degrees or more. Even if a thin cylinder having a diameter of preferably about 15 mm and more preferably about 10 mm is assumed, it is preferable that the angle of the gap is 45 degrees or more.

In the present invention, the "wide-angle forming portion" may be provided on the handle portion, on the hydrant body, or on both the handle portion and the hydrant body. The gap between the hydrant main body and the handle is formed by the hydrant main body and the wide-angle forming part when the wide-angle forming part is provided in the handle, and the handle and the wide-angle when the wide-angle forming part is provided in the hydrant main body. When the wide-angle forming portion is provided in both the handle portion and the hydrant main body, the wide-angle forming portion is formed.

In either case where the wide-angle forming portion is provided on the handle portion or the wide-angle forming portion is provided on the water faucet main body, it is preferable that the wide-angle forming portion is formed to be convexly curved toward the gap. It is. This is because it becomes easy to secure an angle of 45 degrees or more as the angle of the gap.

Next, means adopted by the invention of claim 4 is:
The water tap according to any one of claims 1 to 3, wherein the handle has an opening.

In general, when the handle is provided with an opening, the operator can insert his / her finger into this opening and the handle becomes easier to operate. On the other hand, the handle is inserted into this opening. The finger is likely to protrude toward the hydrant main body, and the finger is easily pinched. According to the present invention, it is possible to prevent the finger from being pinched even in the water tap in such an embodiment.

Next, the means adopted by the invention of claim 5 is as follows:
The hydrant according to any one of claims 1 to 4, wherein the handle is disposed on a side of the hydrant main body.

Generally, when the handle is arranged on the side of the water faucet body, the operation can be performed while the palm is turned sideways, so that the handleability of the handle is improved. On the other hand, the operator's finger turned sideways. Is easy to protrude to the side of the hydrant body,
Fingers are easily pinched. According to the present invention, it is possible to prevent the finger from being pinched even in the water tap in such an embodiment.

[0021]

FIG. 1 shows an example of a water tap according to the present invention. The hydrant includes a hydrant main body 10, a first handle 30 disposed on a side of the hydrant main body 10, a second handle 50 disposed above the hydrant main body 10,
It has. The hydrant main body 10 of this embodiment includes a main body having a flow passage therein and a valve device and the like, and a cover for covering the main body, and the cover provides a sense of unity with the first handle 30. Is increased to improve the design of the entire water faucet, but the water supply body in each of the present inventions is not limited to this, and may not be provided with a cover.

In the hydrant of this embodiment, the "handle" of the present invention is constituted by the first handle 30. When the hydrant has a plurality of handles, the present invention is applied to all handles. May be. The first handle 30 switches the water discharge direction to the Karan 15 or a shower (not shown), and adjusts the water discharge amount and controls the water discharge. The second handle 50 controls the water discharge temperature. To adjust.

According to the fifth aspect of the present invention, the first handle 30 is arranged to protrude from the side of the water tap main body 10. However, in each of the first to fourth aspects of the present invention, the handle may be disposed at another location such as above, forward, or below the water faucet main body 10. In this example, the first handle 30 is in a state of being close to the water tap main body 10 (for example, 1 to 30 mm).
(Preferably, about 1 to 10 mm, more preferably about 1 to 5 mm) to enhance the sense of unity between the first handle 30 and the hydrant main body 10.
In the present invention, the handle and the hydrant main body can be separated to some extent. However, in this case, it is preferable that the distance between the handle and the hydrant main body be kept at 50 mm or less for the following reason. First, the first reason is that if this distance exceeds 50 mm, the sense of unity between the handle and the water tap main body may be impaired. The second reason is that the distance is 5
When the distance exceeds 0 mm, the handle is sufficiently separated from the hydrant main body, so that there is no possibility that a finger is pinched, and "prevention means"
This is because there is no need to provide a.

The first handle 30 is connected to the hydrant main body 1.
A handle main body 31 attached to the operation shaft of the switching valve device incorporated in the main body 0 so as to be integrally rotatable;
1 and a handle portion 32 protruding from the handle 1. Here, the upper surface of the handle portion 32 is substantially flush with the upper surface 12 of the water tap main body 10. As a result, the design of the entire water faucet is particularly excellent.

Further, the handle portion 32 has the opening 33 according to the invention of claim 4, whereby the operability of the first handle 30 is improved. A substantially wall-shaped prevention means 35 extends from the lower surface of the handle 32 on the side of the water tap main body 10. The prevention means 35 functions as the “projection prevention part” in the invention of claim 2 and also functions as the “wide-angle forming part” in the invention of claim 3, but the “prevention means” in the invention of claim 1 "
Is not limited to the embodiment of this example. For example, it may have one of the functions of the protrusion preventing portion and the wide-angle forming portion. Further, in each of the present inventions, the prevention means 35 is extended from a portion of the upper surface 12 of the hydrant body 10 on the side of the handle 32, and a portion of the handle portion 32 and the portion of the handle 32 on the side of the hydrant body 10. The prevention means 35 can be extended from both the lower surfaces. Further, a concave portion as a “preventing means” may be provided on the hydrant body side or the like, and the finger may be prevented from being pinched by allowing the finger between the hydrant main body 10 and the grip portion 32 to escape by the concave portion. However, in order to sufficiently secure the design of the hydrant, as shown in this example, the handle 32
It is preferable to provide a preventive means at an inconspicuous portion such as the lower surface of the device.

In the hydrant of this embodiment, as shown in the figure, the handle 3
When the upper surface of 2 is substantially flush with the upper surface 12 of the water tap main body 10, the water is stopped. When the handle 32 is tilted downward to rotate the handle main body 31, water is discharged through the cull 15 and the amount of water discharged is adjusted according to the amount of rotation of the handle main body 31.

On the other hand, as shown in FIGS.
The handle part 32 is tilted upward to operate the handle body 31
Is rotated, water is discharged through the shower, and the amount of water discharged is adjusted according to the amount of rotation of the handle main body 31. Then, when the state of the shower water discharge is stopped or the state of the shower water discharge is switched at a stretch, the handle portion 32 is tilted downward. At this time, since the prevention unit 35 functions as a projection prevention unit, the finger of the hand that operates the first handle 30 is blocked by the prevention unit 35, and it is difficult for the finger to protrude toward the hydrant main body 10.

However, as shown by the broken line in FIG. 2B, the finger 80 of the hand to be operated protrudes from the prevention means 35, the finger 80 of another hand not performing the operation, or the finger of another person's hand. 8
In the case where 0 is placed on the hydrant main body 10, these fingers 80 enter the gap between the handle 32 on which the water stop operation is performed and the upper surface 12 of the hydrant main body 10. There is. However, in the present example, the prevention unit 35 functions as a wide-angle forming unit, and prevents the finger 80 from being pinched. That is, in a state where the finger 80 can enter the gap, the angle of the gap formed by the handle portion 32 provided with the prevention means 35 and the upper surface 12 of the water tap main body 10 becomes 45 degrees or more, thereby preventing the finger from being pinched. And in the state where the angle of the gap is less than 45 degrees,
As shown in FIG. 2C, the finger 80 cannot enter the gap, so that the finger 80 is not pinched. Less than,
This will be described in detail.

As shown in FIGS. 3A to 3C, the lower edge 37 of the handle portion 32 provided with the preventing means 35, that is, the gap between the lower edge 37 of the preventing means 35 and the upper surface 12 of the water tap main body 10. 38, the pressing force F in the rotation direction of the first handle 30 is applied to the finger 80 from the lower edge 37 of the prevention means 35.
Is added. The pressing force F includes a “pressing component force T” which is a stress in a direction of pressing the finger 80 against the upper surface 12 of the water faucet main body 10 and a “releasing component force S” which is a stress in a direction in which the finger 80 is released outside the gap 38. ].

Here, as shown in FIG. 3A, when the lower edge 37 of the prevention means 35 contacts the finger 80, the gap 3
If the angle (α) of 8 is 45 degrees, S = T. Then, as shown in FIG. 3B, this angle (α)
Is less than 45 degrees, S <T. in this way,
When S <T, the finger 80 does not escape outside the gap 38 due to the "releasing component S", and the finger 80 is pinched by the "pressing component T". That is, if the finger 80 can enter the gap 38 even if the angle (α) of the gap 38 is 45 degrees or less, the finger 80 is pinched. On the other hand, as shown in FIG. 3C, when the angle (α) of the gap 38 exceeds 45 degrees, even if the finger 80 exists in the gap 38, S> T, and the “releasing component S” As a result, the finger 80 escapes to the outside of the gap 38, and pinching of the finger 80 is avoided.

In this embodiment, the lower edge 3 of the preventing means 35
7, that is, the edge of the wide-angle forming portion on the side of the gap 32 is linear, but in the invention of claim 3, as shown in FIG. It can also be curved. According to such an embodiment, it is easy to secure an angle of 45 degrees or more as the angle of the gap.

Further, the water tap according to the present embodiment is not provided with a preventing means which functions when the handle portion 32 is tilted upward from below. This is because the risk of finger pinching is particularly high when the tilt operation is performed from above to below, and this risk is not so high when the tilt operation is performed from below to above. However, in a mode in which the handle portion 32 is tilted downward from the lower surface of the water faucet main body 10 as shown in FIG. 5, as shown in FIG. The prevention means 35 may be formed. On the other hand, the prevention means 35 may be extended from the upper surface of the handle portion 32, but in order to improve the design of the handle portion 32, the embodiment shown in FIG. 5 is preferable.

In the present embodiment, a description is given of a water faucet in which a handle portion 32 arranged on the side of the water faucet main body 10 is tilted upward from the upper surface 12 of the water faucet main body 10 and downward from the lower surface thereof. However, in the present invention, the handle 32
However, it also includes a faucet that is operated to tilt only upward or downward only of the faucet main body 10. Further, in this example, a substantially wall-shaped prevention means 35 is provided only on the portion of the lower surface of the handle portion 32 on the side of the faucet main body 10, and the handle portion 3 is provided.
Although the boundaries between 2 and the prevention means 35 are relatively clear, these boundaries need not necessarily be clear in the present invention. For example, the prevention means 35 can be extended from the entire lower surface of the handle 32.
