Description

  The present invention relates to a water faucet device, and more particularly, to a device having a feature in a structure for restricting rotation with respect to a water discharge pipe having a water discharge port at a tip portion.

Conventionally, a cylindrical base end portion of a water discharge pipe having a water discharge port at a distal end portion is externally fitted to a support portion for the water discharge pipe, and the base end portion of the water discharge pipe is rotatably supported by the support portion. Water faucet devices are widely used.
In such a faucet device, a pair of contact portions are provided on the outer peripheral surface of the support portion so as to be separated from each other in the rotation direction of the water discharge pipe, while a stopper protrusion is provided in a state of penetrating in the radial direction at the base end portion of the water discharge pipe. A water faucet device that regulates the rotation of a water discharge pipe by bringing a stopper projection into contact with a contact portion during the rotation of the water discharge pipe is conventionally known.
For example, this type of faucet device is disclosed in Patent Document 1 below.
FIG. 13 shows an example.

In the figure, reference numeral 200 denotes a water discharge pipe having a water discharge port at the tip, and 202 denotes a support part (here, a faucet body) that supports the water discharge pipe 200.
Reference numeral 204 denotes a cylindrical base end portion of the water discharge pipe 200, and the water discharge pipe 200 is externally fitted to the support portion 202 and is rotatably supported by the support portion 202.

  As shown in FIG. 13A, the support portion 202 is provided with contact portions 206 </ b> A and 206 </ b> B at positions separated in the rotation direction of the water discharge pipe 200, while the base end portion 204 of the water discharge pipe 200 is provided at the base end portion 204. The stopper projection 208 penetrates the base end portion 204 in the radial direction, and the tip end portion is provided so as to protrude inward of the base end portion 204.

  In this faucet device, when the water discharge pipe 200 is rotated in the counterclockwise direction in the figure, the stopper projection 208 comes into contact with the contact portion 206A, and the water discharge pipe 200 is restricted in rotation there and is discharged in the reverse direction in the clockwise direction in the figure. When the water pipe 200 is rotated, the stopper projection 208 hits the contact portion 206B, and the water discharge pipe 200 is restricted in rotation there.

However, in the case of this faucet device, there is a problem that the rotation range of the water discharge pipe 200 is constant and the rotation range cannot be changed according to the situation of the installation site of the faucet device.
For example, when attaching the faucet device to the sink, depending on the size and shape of the sink, or when the mounting position is the center position of the sink, the position is biased to the right side, or the position is biased to the left side Thus, the appropriate rotation range of the water discharge pipe 200 is different.
Moreover, when the sink is not installed facing the wall and is installed independently in the center of the kitchen, the necessary rotation range of the water discharge pipe is naturally different.

However, in the faucet device shown in FIG. 13, the rotation range of the water discharge pipe 200 cannot be adjusted to an appropriate rotation range according to the situation at the installation site.
In this case, the usability of the water faucet device is deteriorated, and in some cases, the water outlet at the tip of the water discharge pipe may be removed from the sink and accidentally discharged outside the sink.
Therefore, it is desirable for the faucet device to be able to adjust the rotation range of the water discharge pipe according to the situation of the installation site.

Furthermore, when adjusting the rotation range of the water discharge pipe, it is desirable to be able to adjust the rotation range of the water discharge pipe without disassembling (separating) the faucet device including the water discharge pipe at the installation site.
If the faucet device including the water discharge pipe is disassembled to adjust the rotation range of the water discharge pipe at the installation site, the faucet will not return to its original proper assembly state when the water faucet device is assembled again. May be installed, or the seal member may be damaged during disassembly or reassembly, and the reliability of the seal may be impaired.

  The structure for restricting the rotation of the water discharge pipe is also disclosed in Patent Document 2 below. However, the one disclosed in Patent Document 2 also cannot adjust the rotation range of the water discharge pipe according to the situation of the installation site of the faucet device.

  On the other hand, Patent Document 3 and Patent Document 4 disclose ones in which the rotation range of the water discharge pipe can be adjusted, but those disclosed in Patent Document 3 and Patent Document 4 indicate the rotation range of the water discharge pipe. In order to change and adjust, there is a problem that the faucet device must be once disassembled into each member.

By performing the dynamic operation, the mixing ratio of water and hot water is changed, and the temperature of the mixed water is adjusted.
The mixed water flows out from the mixing chamber 34 through the outflow port 36 downward in the figure, and further flows through the water discharge pipe 16 and is discharged from the water discharge port 18 at the tip.

As shown in FIG. 3, the outer peripheral surface of the faucet body 15, specifically, the outer peripheral surface of the bottom portion 38 is provided with a plurality of contact portions for restricting the rotation of the water discharge pipe 16 at different radial positions. ing.
Specifically, a pair of first contact portions 40A and 40B as contact portions of the innermost position in the radial direction, a pair of second contact portions 42A and 42B at a further outer position, and a pair of second contact portions 42A and 42B at a further outer position thereof. The third contact portions 44A and 44B are provided.

Here, each of the contact portions 40A, 40B, 42A, 42B, 44A, and 44B has a contact surface that is a radial surface centered on the axis of the bottom portion 38.
These three pairs of contact portions 40A and 40B, 42A and 42B, 44A and 44B are provided at different positions in the circumferential direction.

Specifically, the first contact portions 40A and 40B on the innermost radial direction are on the center side of the rotation range of the base end portion 20 in the water discharge pipe 16, and the third contact portions 44A and 44B on the outermost radial direction are At the extreme end position of the rotation range of the base end portion 20, the second contact portions 42 </ b> A and 42 </ b> B between them are provided so as to be positioned between them.
In this example, with respect to the center position of the rotation range of the water discharge pipe 16, that is, the base end portion 20, the one contact portion 40A, 42A, 44A in the three pairs of contact portions is the other contact portion 40B, 42B. , 44B are arranged at symmetrical positions in the rotational direction.

On the other hand, the base end portion 20 of the water discharge pipe 16 is provided with a mounting hole 46 penetrating in the radial direction, and a stopper projection 48 made of a male screw member is attached thereto.
Here, the mounting hole 46 has a female screw portion 50 and a concave portion 52 having a larger diameter than this, and the male screw portion 54 of the stopper projection 48 is screwed into the female screw portion 50, and the stopper projection is in the concave portion 52. Forty-eight heads 56 can be accommodated.
Reference numeral 58 denotes a cap for concealing the stopper projection 48 made of a male screw member.

  Here, when the stopper protrusion 48 is screwed in to the deepest position, the distal end portion thereof can abut against the contact portions 40A and 40B located at the innermost position in the radial direction. It will be in the state which opposes a rotation direction.

4 to 6 show the operation of this embodiment.
First, FIG. 4 (A) shows a case where the rotation range of the water discharge pipe 16 is restricted to the narrowest. At this time, the stopper projection 48 is placed on the first contact portions 40A and 40B whose tip portions are at the radially innermost positions. It is possible to abut against the other contact portions 42A and 42B, 44A, 44B.

In this state, from the position shown in FIG. 3 when rotating the water discharge pipe 16 in the counterclockwise direction in the drawing, the water discharge pipe 16 is the angle theta ₁ stopper projection 48 abuts portion 40B in contact with the at rotated, where the water discharge pipe 16 Rotation is regulated.
Also is rotated counterclockwise the water discharge pipe 16 from the position shown in FIG. 3, where the water discharge pipe 16 is rotated in the counterclockwise direction by theta _1, abuts against the stopper projection 48 abuts portion 40A, where the water discharge pipe 16 Rotation is regulated.

On the other hand, as shown in FIG. 5, the stopper projection 48 is screwed back from the state shown in FIG. 3 by a certain amount in the radial direction, and its tip is positioned so as to be able to contact the intermediate contact portions 42A and 42B. If this is done (at this time, the tip of the stopper projection 48 is in a state where it cannot contact the contact portions 40A and 40B, 44A and 44B), the water discharge pipe 16 is rotated clockwise as shown in FIG. 5 (A). When the water discharge pipe 16 is rotated by an angle θ ₂ larger than θ ₁ , the stopper projection 48 comes into contact with the contact portion 42B, and further rotation of the water discharge pipe 16 is restricted there.
When the water discharge pipe 16 is rotated counterclockwise, which is the opposite direction, when the water discharge pipe 16 is rotated by an angle θ ₂ from the central position, the stopper projection 48 comes into contact with the contact portion 42A, and the water discharge pipe 16 is further rotated. Is regulated.

As shown in FIG. 6, the stopper projection 48 is further unscrewed and retracted so that its tip can be brought into contact with the contact portions 44A and 44B at the radially outermost position (in this case, the stopper projection 48). Are in contact with the contact portions 40A and 40B, 42A and 42B), and when the water discharge pipe 16 is rotated clockwise as shown in FIG. 6A, the water discharge pipe 16 becomes larger. When the rotated angle theta _3, or also the water discharge pipe 16 as shown in (B) where is rotated by a large angle theta ₃ by the counterclockwise direction, the stopper projection 48 abuts the respective contact portion 44B or 44A Further rotation of the water discharge pipe 16 is restricted.

  As described above, according to the present embodiment, the amount of screwing in the radially inward direction of the stopper projection 48 or the amount of pulling in the radially outward direction is adjusted only from the outside of the proximal end portion 20 of the water discharge pipe 16. The position of the rotation restriction of the water discharge pipe 16 can be easily changed and adjusted.

  Here, the contact portions 40A and 40B, 42A and 42B, 44A and 44B are provided in three steps in the radial direction, but this may be provided in two steps or in a plurality of steps of four or more. Alternatively, the circumferential positions of the contact portions 40A, 40B, 42A, 42B, 44A, and 44B can be variously changed, and the position of rotation regulation of the water discharge pipe 16 can be variously changed accordingly. . That is, the rotation range of the water discharge pipe 16 can be adjusted variously.

  According to this embodiment, when adjusting the rotation range of the water discharge pipe 16, the stopper protrusion 48 is simply operated from the outside of the base end portion 20 of the water discharge pipe 16 to adjust the amount of protrusion inward in the radial direction. Therefore, the rotation range of the water discharge pipe 16 can be adjusted to an appropriate rotation range at the installation site without disassembling the faucet device 10 including the water discharge pipe 16.

  Therefore, when the faucet device 10 is disassembled, the faucet device 10 is installed without being assembled in the original proper state when it is assembled again, or the seal member is damaged during disassembly and reassembly. Therefore, there is no problem that the reliability of the seal is impaired.

  In the above example, the restricting position of rotation of the water discharge pipe 16 is changed by changing the screwing amount of one stopper protrusion 48 in the radial direction, that is, the protruding amount, but it is shown in FIG. Stopper projections 60-1, 60-2, 60-3 made of a plurality of types of male screw members having different lengths are prepared, and the water discharge pipe 16 required at the installation site of the faucet device 10 is prepared. Depending on the rotation range, any one of the stopper protrusions 60-1, 60-2, 60-3 can be selected and used to adjust the rotation range of the water discharge pipe 16.

  Here, the stopper protrusions 60-1, 60-2, 60-3 are similar to the above in that they are provided with a male screw portion 54 and a large-diameter head portion 56, but these are the female screw portions in the mounting hole 46. A portion protruding from 50 is a non-screw portion 62. However, these can also be used as male threads.

  When such a stopper protrusion is used, the stopper protrusions 60-1, 60-2, 60-3 protrude from the outer surface of the base end portion 20 of the water discharge pipe 16 in the stopper action state shown in FIGS. The advantage that can be avoided is obtained.

Next, FIG. 8 shows another embodiment of the present invention.
In this example, a plurality (three in this case) of mounting holes 64-1, 64-2, 64-3 are provided in the base end portion 20 of the water discharge pipe 16, and stopper protrusions 66-1, 66 each made of a male screw member are provided. This is an example in which -2, 66-3 are attached and they are brought into contact with the contact portions 44A, 44B on the faucet body 15 side.

In this example, in the state shown in FIG. 8 (A), rotating the water discharge pipe 16 in the clockwise direction as shown in FIG. 9 (A), where the water discharge pipe 16 is rotated by an angle theta _4, The stopper projection 66-3 located at the rightmost position in the drawing abuts against the contact portion 44B, where the rotation of the water discharge pipe 16 is restricted.

Further, as shown in FIG. 9B, when the water discharge pipe 16 is rotated counterclockwise, which is the opposite direction, the water discharge pipe 16 is rotated by an angle θ ₄ and is now at the leftmost position in the figure. The stopper projection 66-1 comes into contact with the contact portion 44A, where further rotation of the water discharge pipe 16 is restricted.
That is, in this example, among the three stopper protrusions 66-1, 66-2, 66-3, two stopper protrusions 66-1, 66-3 on the left side and the right side are selected as the stopper action, and their two The rotation of the water discharge pipe 16 is restricted by the stopper action.

At this time, the stopper protrusion 66-2 at the middle position does not perform any stopper action. It is simply attached to the attachment hole 64-2 and held there.
Therefore, in this example, the stopper protrusion 66-2 may be extracted from the mounting hole 64-2.

  On the other hand, in the example of FIG. 10, the stopper projection 66-1 at the leftmost position in the drawing is extracted from the mounting hole 64-1, and the remaining two stopper projections, that is, the stopper projection 66-2 in the middle in FIG. An example in which the right-side stopper protrusion 66-3 is selected as a stopper protrusion to be stopped and brought into contact with the abutting portions 44A and 44B, thereby changing the restriction position with respect to the rotation of the water discharge pipe 16. It is.

In the example specifically illustrated in FIG. 10, rotating the water discharge pipe 16 as indicated in a clockwise direction in FIG. 11 (A), the water discharge pipe 16 at rotated by an angle theta _4, in the figure in the right The stopper projection 66-3 contacts the contact portion 44B, where further rotation of the water discharge pipe 16 is restricted.

On the other hand, when the water discharge pipe 16 is rotated counterclockwise as shown in FIG. 11B, when the water discharge pipe 16 is rotated by an angle θ ₅ larger than θ ₄ , the stopper projection 66-2 is brought into contact with the stopper protrusion 66-2. 44A is contacted, and further rotation of the water discharge pipe 16 is restricted there.

  In this example, the stopper protrusion 66-1 on the left side in the figure is extracted and the remaining two stopper protrusions 66-2 and 66-3 act as a stopper. It is also possible to extract the stopper protrusion 66-3 and perform the stopper action with the remaining two stopper protrusions 66-1 and 66-2.

In this case, the water discharge pipe 16 where is rotated by an angle theta ₅ clockwise, the stopper projection 66-2 abuts on the contact portion 44B, the rotation of the further water discharge pipe 16 is restricted, and in the opposite direction rotation of the water discharge pipe 16 to a counterclockwise direction, the water discharge pipe 16 at rotated by an angle theta _4, the stopper projection 66-1 abuts on the contact portion 44A, where a further rotation of the water discharge pipe 16 is restricted The

In the example shown in FIG. 10, the leftmost stopper protrusion 66-1 is described as being extracted. However, as shown in FIG. 12, the stopper protrusion 66-1 is not completely extracted, and the stopper action In other words, the stopper projection 66-1 can be retracted in a non-operating state, and the stopper operation can be performed by the remaining two stopper projections 66-2 and 66-3. is there.
This also applies to the stopper protrusion 66-3 on the right side in the drawing.

Also in this embodiment, the adjustment operation of the rotation range of the water discharge pipe 16 can be performed without disassembling the faucet device 10 including the water discharge pipe 16 at the installation site.
In addition, the rotation range of the water discharge pipe 16 can be adjusted in various ways by selecting two stopper projections to be used as a stopper in any combination from three, and there is an advantage that the degree of freedom of adjustment is high.

  In this example, three mounting holes are provided. However, only two mounting holes are provided, and a stopper projection is attached to one of the mounting holes, or conversely, four mounting holes are provided. It is also possible to provide a plurality of two or more and provide stopper projections in the stopper working state in the mounting holes selected therefrom.

Although the embodiments of the present invention have been described in detail above, these are merely examples.
For example, in each of the above embodiments, the stopper protrusion is formed by a male screw member. However, in some cases, the stopper protrusion can be formed by a shaft-like member that does not have a male screw portion, or the like. In the form, the faucet body itself forms the support part of the water discharge pipe, but it is also possible to configure the support part with a member other than the faucet body. It can be configured in a form to which
