BACKGROUND OF THE INVENTION
The present invention relates to a faucet provided such that a water discharge device such as a shower head can be pulled out from an outer tube extending from a faucet body and can be pushed into the outer tube.
[0002]
[Prior art]
As this kind of faucet, the present applicant has developed a kitchen faucet provided with a water discharge head 122 that can be pulled out and pushed into a holder 121 extending from a faucet body 120 as shown in FIG. This kitchen faucet has an inner pipe 124 that communicates with a discharge passage 123 inside the faucet body 120 inside a cylindrical holder 121. A flexible pipe 125 connected to the water discharge head 122 is slidably attached to the inner pipe 124. An annular sliding body 127 slidably contacting the inner tube 124 via a packing 126 is fixed to the lower end of the flexible tube 125. The water supplied from the faucet body 120 to the inner pipe 124 by the operation of the lever 130 is supplied to the water discharge head 122 through the flexible pipe 125. When the water discharge head 122 is pulled out from the holder 121, the sliding body 127 moves along the inner tube 124. At this time, the sliding body 127 maintains a watertight state between the inner tube 124 and the flexible tube 125. For this reason, the water discharge head 122 can be freely used in a state where it is pulled out from the faucet body 120.
[0003]
[Problems to be solved by the invention]
The faucet inner pipe 124 was fixed to the insertion hole 129 of the base 128 attached to the faucet body 120 by screwing, as shown in the enlarged view of part A of FIG. In this case, in general component accuracy and assembly accuracy used for the faucet, it is inevitable that the distal end side of the inner tube 124 is biased radially outward from the central axis of the holder 121. For this reason, when the water discharge head 122 is pulled out from the holder 121, the outer peripheral surface of the sliding member 127 becomes the inner peripheral surface of the holder 121 as the sliding member 127 moves toward the distal end side of the inner tube 124 as shown in FIG. 13. It will be strongly pressed. As a result, since the force required when the water discharge head 122 is pulled out or pushed in changes depending on the position where the water discharge head 122 is pulled out, the water discharge head 122 cannot be pulled out and pushed in smoothly. there were. In some cases, the sliding body 127 is bitten into the holder 121 and cannot be pushed in.

It is generated and supplied to the outside from the discharge channel 16.
[0013]
A substantially cylindrical base portion 17 is rotatably attached to the faucet body 11, and a discharge passage 16 is communicated with the inside of the base portion 17. A holder 18 as an outer tube extending obliquely upward is fixed to the base portion 17. The holder 18 is formed in a cylindrical shape having the same inner diameter as the base portion 17, and a water discharge head 19 as a water discharger is supported at the tip thereof. This water discharge head 19 is a well-known water discharge tool, for example, a switching type between a shower flow and a direct current.
[0014]
A cylindrical inner tube 20 is disposed inside the holder 18, and the proximal end of the inner tube 20 is fixed to the support body 21 disposed in the base 17 at the center in the radial direction of the base 17. As shown in FIG. 1, the support 21 includes a large diameter portion 22 on the water discharge head 19 side and a small diameter portion 23 on the faucet body side. The outer diameter of the large-diameter portion 22 is slightly smaller than the inner diameter of the base portion 17, and the space between the inner peripheral surface of the base portion 17 is sealed by an O-ring 24 as a packing attached to the peripheral groove 22 a on the outer peripheral surface. . The O-ring 24 elastically supports the support body 21 in a state where it floats from the inner peripheral surface of the base portion 17. An insertion hole 25 passes through the center of the small diameter portion 23, and the inner tube 20 is fixed to the insertion hole 25 in a state of communicating with the base 17 side. The support body 21 is held so as not to come out of the base portion 17 by a stopper member 26 attached to the circumferential groove 17 a of the base portion 17. As the support body 21 is supported by the base portion 17 via the O-ring 24, the inner tube 20 is centered on the base end portion thereof, and the distal end side is the center of the base portion 17 and the holder 18 as shown in FIG. It can swing freely in the radial direction around the axis L.
[0015]
As shown in FIG. 2, a flexible pipe 27 as an extension pipe connected to the water discharge head 19 is attached to the inner pipe 20 so as to be slidable in the central axis direction of the inner pipe 20. As shown in FIG. 1, the flexible tube 27 includes an inner rubber hose 28a and a bellows tube 28b covering the rubber hose 28a. An annular sliding body 29 that slides in a watertight manner with respect to the inner tube 20 is fixed to the lower end of the flexible tube 27.
[0016]
The sliding body 29 includes a small-diameter portion 30 on the base 17 side and a large-diameter portion 31 on the water discharge head 19 side. The inner tube 20 is inserted into the insertion hole 32 provided at the center of the small diameter portion 30, and the gap between the inner tube 20 and the small diameter portion 30 is sealed by the lip packing 33 provided on the inner peripheral surface of the insertion hole 32. ing. The large diameter portion 31 has an outer diameter slightly smaller than the inner diameter of the holder 18, and a recess 34 for fixing the flexible tube 27 is provided on the water discharge head 19 side. An outer fixed ring 35 that is externally fitted to the rubber hose 28 a of the flexible tube 27 is fixed to the recess 34, and an inner fixed ring 36 is inserted inside the rubber hose 28 a inside the outer fixed ring 35. The lower end of the rubber hose 28 a is fixed in the recess 34 by the outer fixed ring 35 and the inner fixed ring 36. The space between the outer stationary ring 35 and the recess 34 is sealed by an O-ring 37 provided on the inner peripheral surface of the recess 34. Further, the bellows tube 28b is fixed to the outer fixed ring 35 by a stopper member 38 that is fitted on the end of the outer fixed ring 35 on the water discharge head 19 side.
[0017]
The sliding body 29 includes a first annular chamber A formed between the support body 21 and the sliding body 29 and a second annular chamber B formed on the other side of the sliding body 29 in the space within the base portion 17 and the holder 18. It is divided into and. The first annular chamber A is always in communication with the outside air through a drain hole 39 provided in the base portion 17. The drain hole 39 drains the water that has entered the holder 18 to the outside. Further, the drain hole 39 is formed so that the negative pressure or the positive pressure generated in the first annular chamber A is not increased as much as possible when the sliding body 29 moves along the inner tube 20.
[0018]
Next, the operation of the present embodiment configured as described above will be described.
When the water discharge head 19 is pulled out from the holder 18, the sliding body 29 moves from the proximal end side to the distal end side of the inner tube 20. At this time, air is supplied to the first annular chamber A, which increases with the movement of the sliding body 29, through the drain hole 39 and the gap between the inner peripheral surface of the base 17 or the holder 18 and the sliding body 29. Therefore, this space is unlikely to become negative pressure, and resistance to movement of the sliding body 29 is unlikely to occur. For this reason, the water discharge head 19 can be pulled out smoothly. On the contrary, when the water discharge head 19 is pushed in, air is discharged from the first annular chamber A into the outside air through the drain hole 39 and the gap between the inner peripheral surface of the base 17 or the holder 18 and the sliding body 29. Therefore, resistance to the movement of the sliding body 29 hardly occurs. For this reason, the water discharge head 19 can be pushed in smoothly.
[0019]
At this time, since the support body 21 that fixes the lower end of the inner tube 20 is elastically supported by the O-ring 24 in a state of floating from the inner peripheral surface of the base portion 17, the inner tube 20 is centered on the proximal end side. The front end side can swing freely in the radial direction from the central axis of the holder 18. For this reason, when the sliding body 29 moves to the distal end side of the inner tube 20, the position is corrected so that the center axis of the inner tube 20 coincides with the center of the holder 18 as shown in FIG. 3. The sliding body 29 is not strongly pressed against the inner peripheral surface of the holder 18 by 20.
[0020]
Next, effects of the present embodiment described in detail above will be listed.
(1) The inner tube 20 is supported by a support 21 that is elastically supported in a state where it floats from the inner peripheral surface of the base portion 17 by an O-ring 24 so that the distal end side thereof can be displaced in the radial direction with respect to the holder 18. Its proximal end is fixed. For this reason, even if the sliding body 29 moves to the distal end side of the inner tube 20, it is not strongly pressed against the inner peripheral surface of the holder 18, and no large frictional resistance is generated between the holder 18 and the holder 18. Therefore, when pulling out the water discharge head 19 from the holder 18 and pushing it into the holder 18, the necessary force is unlikely to change, and the drawing and pushing can be performed more smoothly.
[0021]
(2) The support body 21 in which the base end portion of the inner tube 20 is fixed at the radial center of the base portion 17, the O-ring 24 that seals between the support body 21 and the base portion 17, and the support body 21 from the base portion 17. The supporting member 21 is elastically supported in a state where it floats through the O-ring 24 by the stop member 26 that is held so as not to come off. Therefore, it can be implemented with a simple structure without using special parts.
[0022]
(3) Since the flexible tube 27 having flexibility is attached to the inner tube 20, the water discharge head 19 drawn out from the holder 18 can be used in a more free position and in a more free orientation.
[0023]
(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. The present embodiment differs from the first embodiment only in that the support body 21 of the first embodiment is replaced with the support body 40, and the governor 45 is provided on the support body 40. Only 40 and governor 45 will be described in detail.
[0024]
As shown in FIG. 5, the support body 40 of this embodiment includes a large-diameter portion 41 on the faucet body 11 side and a small-diameter portion 42 on the water discharge head 19 side. An O-ring 43 that seals between the large-diameter portion 41 and the base portion 17 is provided in the circumferential groove 41 a provided on the outer peripheral surface of the large-diameter portion 41. Further, the O-ring 43 elastically supports the support body 40 in a state where it floats from the inner peripheral surface of the base portion 17. A well-known governor 45 serving as a flow rate regulator is fixed by a stop member 46 in a recess 44 provided on the faucet body 11 side of the large diameter portion 41. The governor 45 restricts the flow rate of water supplied from the faucet body 11 to the water discharge head 19 to a predetermined value or less. An insertion hole 47 penetrating in the direction of the central axis is formed at the center of the small diameter portion 42, and the inner tube 20 is fixed to the insertion hole 47 so as to communicate with the base 17 side. The support body 40 is held by the stop member 26 so as not to come off the base portion 17 like the support body 21 of the first embodiment. Then, the support body 40 is supported by the base portion 17 via the O-ring 43, so that the inner tube 20 is centered on the base end portion thereof, and the distal end side thereof is radially centered on the central axis L of the base portion 17 and the holder 18. You can swing freely.
[0025]
According to the present embodiment configured as described above, even when the lever handle 14 is operated to supply a large amount of water from the faucet body 11 to the water discharge head 19, the lever handle 14 is fixed to the support body 40. The governor 45 limits the maximum flow rate of water supplied from the faucet body 11 to the water discharge head 19 side to a predetermined flow rate or less. The flow rate of water supplied to the water discharge head 19 is limited to a predetermined flow rate or less. For this reason, since an excessive water pressure is not applied to the water discharge head 19 side, the water discharge head 19 does not jump out of the holder 18 due to the water pressure.
[0026]
The present embodiment configured as described above has the following effects in addition to the effects (1) to (3) of the first embodiment.
(4) Since the support body 40 to which the governor 45 is fixed in advance can be assembled to the base portion 17 before the holder 18 is fixed, the structure for holding the governor 45 is different from the case where the governor 45 is assembled alone. There is no need to provide in the base 17. For this reason, the structure of the base portion 17 is not complicated, and the governor 45 can be easily assembled.
[0027]
(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. The present embodiment is different from the first embodiment in that the sliding body 29 is replaced with the sliding body 50 and only the piston 51 is provided on the sliding body 50. Therefore, only the sliding body 50 and the piston 51 are used. Detailed description.
[0028]
As shown in FIG. 6, the sliding body 50 is formed in a substantially cylindrical shape, and the inner tube 20 is inserted through an insertion hole 52 provided at the center thereof. A gap between the insertion hole 52 and the inner tube 20 is sealed by a lip packing 53 provided on the inner peripheral surface of the insertion hole 52. A concave portion 54 for fixing the flexible tube 27 is provided on the water discharge head 19 side of the sliding body 50. One end of the flexible tube 27 is fixed to the recess 54 by an outer fixed ring 35, an inner fixed ring 36, and a stopper member 38 similar to those in the first embodiment.
[0029]
The sliding body 50 is provided with a plurality of flow paths 55 extending in the radial direction from the bottom of the recess 54 toward the outer peripheral side. Water is supplied to each flow channel 55 through a water channel formed between the inner tube 20 and the flexible tube 27. Each flow channel 55 communicates with the bottom surface of a hole 56 that opens to the outer peripheral surface of the sliding body 50. Each hole 56 is formed in a columnar shape, and a piston 51 that closes the flow path 55 and can be displaced in the radial direction is disposed inside thereof.
[0030]
As shown in FIG. 7, the piston 51 includes a body portion 57 having a diameter smaller than the inner diameter of the hole 56, and a head portion 58 and a foot portion 59 having substantially the same diameter as the inner diameter of the hole 56. 59 is displaced in the radial direction while being in sliding contact with the inner peripheral surface of the hole 56. An O-ring 60 that seals between the hole 56 and the piston 51 is attached to the body 57.
[0031]
The embodiment configured as described above has the following operation.
When the water discharge head 19 is pulled out from the holder 18, air is introduced into the first annular chamber A through the drain hole 39 and the gap between the inner peripheral surface of the base portion 17 or the holder 18 and the sliding body 50. . For this reason, the first annular chamber A is unlikely to become a negative pressure, and resistance due to the negative pressure is less likely to occur with respect to the movement of the sliding body 50.
[0032]
When water is supplied from the faucet body 11, water is introduced into the holes 56 through the flow paths 55 from between the inner tube 20 and the flexible tube 27, and each piston 51 is attached to the base 17 or the holder 18 by the pressure. Pressed against the inner surface. For this reason, the frictional resistance received by each piston 51 becomes a resistance against the movement of the sliding body 50, and the water discharge head 19 is not pushed out of the holder 18 suddenly. In addition, the resistance force which the sliding body 50 receives can be changed by adjusting the pressure receiving area with respect to water by changing the number of pistons 51 and an outer diameter. By this adjustment, the resistance is increased when the water pressure is high and the force to push out the water discharge head 19 is strong, and the resistance is also reduced when the water pressure is low and the force to push out the water discharge head 19 is weak.
[0033]
According to the embodiment described above in detail, the following effects are obtained in addition to (1) to (3) of the first embodiment.
(5) Since the plurality of pistons 51 provided on the sliding body 50 are pressed against the inner peripheral surfaces of the base 17 and the holder 18 by water pressure, the water discharge head 19 is not pushed out of the holder 18 suddenly, and the water discharge head 19 is pulled out. Usability at the time improves.
[0034]
(Fourth embodiment)
Next, a fourth embodiment embodying the present invention will be described with reference to FIGS. In the present embodiment, a circumferential groove 70 is provided in the large-diameter portion 31 of the sliding body 29 of the first embodiment, and a split ring 71 and an O-ring 72 are provided in the circumferential groove 70. Only the removal of the water drain hole 39 is different, so only the peripheral groove 70, the split ring 71 and the O-ring 72 will be described in detail.
[0035]
As shown in FIG. 8, the sliding body 29 of the present embodiment is provided with a circumferential groove 70 on the outer circumferential surface of the large-diameter portion 31, and in the circumferential groove 70, the inner circumferential surface of the base 17 or the holder 18. A split ring 71 is provided in contact with the. The split ring 71 is in sliding contact with the inner peripheral surface of the base 17 and the holder 18 as the sliding body 29 moves. As shown in FIG. 9, the split ring 71 is an annular member cut at one place, and divides the space in the base portion 17 and the holder 18 into a first annular chamber A and a second annular chamber B, The partitioned annular chambers A and B are communicated only through a narrow flow path formed in the cut 71a. A gap between the split ring 71 and the sliding body 29 is sealed by an O-ring 72 provided on the bottom surface of the circumferential groove 70. The O-ring 72 urges the split ring 71 to expand, and presses the outer peripheral surface of the split ring 71 against the inner peripheral surface of the base 17 and the holder 18.
[0036]
The embodiment configured as described above has the following operation.
When the water discharge head 19 is pulled out from the holder 18, air passes from the second annular chamber B defined by the split ring 71 in the base 17 and the holder 18 to the first annular chamber A through the narrow flow path of the split ring 71. Moving. At this time, since the amount of air moving from the second annular chamber B to the first annular chamber A is limited by the flow path of the split ring 71, the first annular chamber A becomes negative pressure and resistance to the movement of the sliding body 29. Occurs. For this reason, even if the lever handle 14 is operated so as to supply a large amount of water and the pressure of the water supplied to the water discharge head 19 becomes excessive, the water discharge head 19 is not pushed out of the holder 18 suddenly. . In addition, a small drain hole may be provided in the base portion 17 and the air inflow amount may be adjusted by the sum of the inflow amount of air from the drain hole and the inflow amount of air from the cut 71a of the split ring 71. .
[0037]
The embodiment described above has the following effects in addition to the effects (1) to (3) of the first embodiment.
(6) Since the air movement in both spaces defined by the sliding body 29 is restricted by the split ring 71 provided on the sliding body 29, the water discharge head 19 is not pushed out of the holder 18 suddenly. Usability is improved.
[0038]
(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIG. The present embodiment is different from the fourth embodiment in that the lip packing 80 is provided in place of the split ring 71 and the O-ring 72 and the air hole 81 is provided in the base portion 17. Only 80 and the air holes 81 will be described in detail.
[0039]
As shown in FIG. 10, in this embodiment, a lip packing 80 that seals between the base 17 or the holder 18 and the sliding body 29 is provided in the circumferential groove 82 provided in the large-diameter portion 31 of the sliding body 29.

Touch the surface.
[0040]
Further, the base portion 17 is provided with an air hole 81 that always communicates the first annular chamber A defined by the sliding body 29 to the outside air. The air hole 81 also serves as the drain hole 39 of the first embodiment. The air hole 81 increases the negative pressure generated in the first annular chamber A to a certain level when the sliding body 29 moves from the proximal end side to the distal end side of the inner tube 20.
[0041]
The embodiment configured as described above has the following operation.
When the water discharge head 19 is pulled out from the holder 18, air is introduced through the air hole 81 into the first annular chamber A, which is partitioned in the airtight state by the lip packing 80 in the base 17 and the holder 18. At this time, since the amount of air introduced into the first annular chamber A is limited by the air holes 81, the first annular chamber A has a negative pressure, and resistance to the movement of the sliding body 29 is generated. For this reason, even if the pressure of the water supplied to the water discharge head 19 side becomes excessive, the water discharge head 19 is not pushed out of the holder 18 suddenly.
