Description

The present disclosure relates to a water discharge stop device.

2. Description of the Related Art Various devices are known as water discharge and stop devices that can discharge and stop water, such as water spray nozzles and cleaning nozzles. These devices are provided with an operating member such as an operating lever. By operating this operating member, it is possible to switch between water discharging and water stopping.

Japanese Patent Laid-Open No. 2005-138056 discloses a water spray nozzle equipped with an operation lever that can switch between water spray and water stop. In this operating lever, in order to ensure a movable range in the pushing direction, a semicircular cut-out portion is formed on the bottom plate 4d (see FIG. 7(d)). In a water-stop state, an opening is formed between the bottom plate and the nozzle body (see FIG. 1).

Japanese Patent Application Publication No. 2005-138056

If there is an opening between the operating member and the main body, water, foreign matter, etc. can enter the main body through this opening. It is also possible to close this opening by providing a wall on the main body side, but if the operating member is configured to be pushed deeply into the main body, the wall protrudes when the operating member is pushed in. This protrusion reduces operability. Further, this protrusion may get caught on something when the device is being dragged and moved, causing damage to the device. By allowing the operating member to enter the main body side when pushed in, the device can be made more compact. In this case, the opening tends to become larger when the operating member pops out.

An object of the present disclosure is to provide a water discharge stop device that suppresses the intrusion of foreign substances and has excellent operability.

In one embodiment, the water discharging device includes a main body, an operating lever that can be switched between a protruding position and a retracted position, and at least one shielding member that is interlocked with the operating lever. The operating lever has a cutout that enters the main body in the retracted position and exits from the main body in the extended position. The shielding member is configured to take a first state when the operating lever is in the protruding position and a second state when the operating lever is in the retracted position by interlocking with the operating lever. In the first state, the shielding member covers the missing portion, and in the second state, the protrusion height of the shielding member is lower than in the first state.

One aspect is that the intrusion of foreign objects and the like is suppressed and operability is improved.

Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate.

Note that, unless otherwise specified, terms such as front, back, upper, and lower are used in this application in accordance with standard postures when the embodiments of this application are used. For example, the downstream side is also referred to as the front, and the upstream side is also referred to as the rear. In other embodiments, these terms may be reasonably interpreted in accordance with the form, posture, etc. of the embodiment.

[First embodiment]
1 and 2 are perspective views of a water discharge stop device 2 according to the first embodiment. FIG. 1 is a perspective view seen from the discharge port 10 side, and FIG. 2 is a perspective view seen from the connection portion 4 side. 3(a) is a plan view of the water discharge stop device 2, and FIG. 3(b) is a sectional view taken along line AA in FIG. 3(a). The water discharge stop device 2 is a water spray nozzle. Since the water discharge stop device 2 can also be used for cleaning purposes, it can also be called a cleaning nozzle. The water discharge stop device 2 is connected to a water supply source (for example, a water supply) having water pressure. For example, the water stop device 2 is connected to a faucet. For example, the water discharge stop device 2 is connected to a water faucet via a boost pump.

The water discharge stop device 2 has a connecting portion 4 , a grip portion 6 , an operating portion 8 , and a discharge port 10 . The connecting portion 4 has an inlet 12 . The grip part 6 has a grip surface 6a. The gripping surface 6a is the outer surface of the gripping portion 6. Further, the water discharge device 2 includes a main flow path WP1, an on-off valve V1, and a flow path forming surface 14. The flow path forming surface 14 defines a main flow path WP1.

Typically, the connection part 4 is connected to a water faucet via a hose. The connection part 4 may be connected to a joint provided at the end of the hose. Water is introduced into the water discharge stop device 2 from the inlet 12 of the connection portion 4 . The main flow path WP1 extends from the inlet 12 to the outlet 10. The on-off valve V1 opens and closes the main flow path WP1. When the on-off valve V1 is closed, the water discharge device 2 enters a water cutoff state. When the on-off valve V1 is opened, the water discharge stop device 2 enters a water discharge state. The on-off valve V1 is opened and closed by operating the operating section 8. By operating the operating unit 8, water discharge and water stop are switched.

The gripping surface 6a is constituted by a circumferential surface. The center line of the gripping surface 6a coincides with the center line of the water discharged from the discharge port 10. The shape of the grip part 6 is not limited. The direction of the center line of water discharge is not limited.

The operating section 8 includes an operating lever 16, an alternate mechanism 18, and a link mechanism 20. The operating lever 16 is supported so as to be rotatable within a predetermined movable range. The operating lever 16 is located at a position where it can be operated by the hand that grips the grip portion 6. In the water discharge stop device 2, the operation part 8 can be operated with one hand while holding the grip part 6.

By operating the operating section 8, the on-off valve V1 is opened and closed. In FIG. 1, FIG. 2, FIG. 3(a), and FIG. 3(b), the water discharge stop device 2 is in a water stop state, and the on-off valve V1 is closed. When the operating lever 16 is pressed once, the on-off valve V1 opens and the water discharge stop device 2 enters the water discharge state. When the operation lever 16 is further pressed, the on-off valve V1 is closed, and the water discharge stop device 2 is brought into a water stop state.

In an unoperated state, the operating lever 16 can assume a first position and a second position. In the first position, the operating lever 16 is in a protruding position compared to the second position. In this application, the first position is also referred to as the protruding position, and the second position is also referred to as the retracted position. The operating lever 16 can be switched between an extended position and a retracted position. In this embodiment, water stops at the protruding position, and water is spouted at the retracted position.

FIG. 4 is an enlarged view showing the vicinity of the operating lever 16. In FIG. 4, (a) shows the protruding position, (b) shows the intermediate position, (c) shows the pushed-in position, and (d) shows the retracted position. When the operating lever 16 in the protruding position is pressed, the operating lever 16 moves through the intermediate position and the pushed-in position to the retracted position. When the pressure is released, the retracted position is maintained. When the operating lever 16 in the retracted position is pressed, the operating lever 16 moves through the pushed-in position and the intermediate position to the extended position. When the pressure is released, the protruding position is maintained. Each time the operating lever 16 is pressed, it repeats mutual transition between the extended position and the retracted position. In this way, the operation of the operating lever 16 is an alternate operation. Due to the alternate mechanism described later, the push-in position is used for switching between the protruding position and the retracted position.

The pushed-in position is the most retracted position in the movable range of the operating lever 16. In switching off water discharge, the operating lever 16 passes through a pushed-in position, which is pushed in further than the retreated position.

Alternate operation of the operating lever 16 is achieved by an alternate mechanism 18. In this embodiment, a heart-shaped cam system is adopted as the alternate mechanism 18. Note that as the alternate mechanism, a known mechanism such as a heart-shaped cam type, a rotary cam type, a ratchet cam type, etc. may be adopted.

The alternate mechanism 18 has a heart-shaped cam 22 and a pin 24. The cam 22 is fixed to the operating lever 16. The pin 24 is made of metal and is a rod-shaped member. The pin 24 is fixed to the main body 2h in a cantilevered state with its end farthest from the cam 22 (lower end in each figure in FIG. 4) being supported. An end 24a (upper end in each figure in FIG. 4) closer to the cam 22 is a free end. This free end is provided with an engaging portion that engages with the cam 22. As shown in FIG. 12(a), which will be described later, this engaging portion is formed by bending the free end side end portion (the upper end portion in each figure of FIG. 4) of the pin 24. When the pin 24 is bent by an external force, it tends to return to its natural state (straightly extended state).

As each figure in FIG. 4 shows, as the operating lever 16 moves from the protruding position to the retracted position, the free end 24a of the pin 24 approaches the cam 22. Although not shown, in the process from the intermediate position to the pushed-in position, the free end 24a comes into contact with the first guide surface 22a of the cam 22, and is further guided by the first guide surface 22a to reach the recess 22b. By engaging the free end 24a with the recess 22b, the operating lever 16 is held in the retracted position. When the operating lever 16 is pressed in this state, the free end 24a disengages from the recess 22b, moves along the second guide surface 22c, and leaves the cam 22. As a result, the operating lever 16 returns to the protruding position.

The link mechanism 20 has a link member 30 rotatably fixed. Each figure in FIG. 4 shows the rotation axis z16 of the operating lever 16. The first end 30a of the link member 30 is slidably engaged with the operating lever 16. This engagement causes the link member 30 to rotate in conjunction with the operating lever 16. The second end 30b of the link member 30 is in contact with the driving valve body D1 of the on-off valve V1 (see FIG. 3(b)). When the link member 30 rotates, the second end 30b moves and the drive valve body D1 moves. In this way, the operating lever 16 is linked to the link mechanism 20. That is, the operating lever 16 is interlocked with the link member 30 and the driving valve body D1. In FIG. 3(b), a rotation axis z30 of the link member 30 is shown.

The driving valve body D1 is always biased by the elastic body 32 in the direction in which the on-off valve V1 is closed (see FIG. 3(b)). In this embodiment, the elastic body 32 is a coil spring. Due to this biasing force, the operating lever 16 is constantly biased in the protruding direction. In other words, the operating lever 16 is always biased to the protruding position. The link member 30 maintains the protruding position of the operating lever 16, which is biased in the protruding direction.

FIG. 5 is a perspective view of the vicinity of the operating lever 16 in the water discharge stop device 2. As shown in FIG. In FIG. 5, (a) shows the protruding position, (b) shows the intermediate position, (c) shows the pushed-in position, and (d) shows the retracted position. The intermediate position is a position between the extended position and the retracted position.

The water discharge stop device 2 has a shielding member S1. The shielding member S1 is interlocked with the operating lever 16. The shielding member S1 is arranged adjacent to the end of the operating lever 16 on the side far from the rotation axis z16. When the operating lever 16 moves in the protruding direction, the shielding member S1 also moves in the protruding direction. When the operating lever 16 moves in the backward direction, the shielding member S1 also moves in the backward direction. In addition, the protrusion direction means the direction in which the protrusion height from the water discharge stop device 2 becomes large, and the retraction direction means the direction in which the protrusion height from the water discharge stop device 2 becomes small.

The water discharge device 2 having the operating lever 16 and the shielding member S1 can be classified into a main body 2h, the operating lever 16, and the shielding member S1. The main body 2h may be a portion of the water discharge stop device 2 excluding the operating lever 16 and the shielding member S1. The outer surface of the main body 2h is formed by an outer shell member 36. A gripping surface 6a of the gripping portion 6 is formed by an outer shell member 36.

In the retracted position, (part of) the operating lever 16 enters the main body 2h. When the operating lever 16 is in the retracted position, (a portion of) the shielding member S1 enters the main body 2h. In the present embodiment, "entering into the main body 2h" may mean entering inside the outer shell member 36.

6(a) is a perspective view of the operating lever 16, FIG. 6(b) is a perspective view of the operating lever 16 from a different angle from FIG. 6(a), and FIG. 6(c) is a perspective view of the operating lever 16. FIG. 6(d) is a plan view of the operating lever 16, and FIG. 6(e) is a rear view of the operating lever 16.

The operating lever 16 has a rotation support part 40, a top wall part 42, a side wall part 44, and a rear wall part 46. The inside of the operating lever 16 is hollow. That is, the operating lever 16 has a hollow portion. This hollow part is open downward. The rotation support part 40 rotatably supports the operating lever 16. In this embodiment, the rotation support part 40 is a through hole into which the rotation axis z16 is inserted. In this embodiment, a member adjacent to the operating lever 16 is provided with a rotating shaft z16, and this rotating shaft z16 is inserted into a through hole of the rotation support portion 40. The rotation support portion 40 may be, for example, a rotation axis z16. In this case, the rotation shaft z16 of the operating lever 16 can be rotatably fixed to the hole in the adjacent member. The upper wall portion 42 constitutes an upper surface 42a of the operating lever 16. The upper surface 42a is the outer surface of the upper wall portion 42. When the operating lever 16 is operated, the upper surface 42a of the operating lever 16 is pressed. The side wall portion 44 has a right side wall portion 44a and a left side wall portion 44b. The cavity is between the right side wall portion 44a and the left side wall portion 44b.

The rotation support portion 40 (rotation shaft z16) is located in front of the operating lever 16. The rear wall portion 46 is located on the rear side of the operating lever 16. The rear wall portion 46 constitutes a rear end surface 46a of the operating lever 16. The rear end surface 46a is the outer surface of the rear wall portion 46.

The rear wall 46 extends between the rear edge of the right side wall 44a and the rear edge of the left side wall 44b. The upper edge of the rear wall 46 is joined to the rear edge of the upper wall 42 .

As shown in FIG. 6(b), the operating lever 16 has a missing portion 50. As shown in FIG. The missing portion 50 is formed by missing the rear wall portion 46. The missing portion 50 forms a portion where the rear wall portion 46 does not exist between the rear edge of the right side wall portion 44a and the rear edge of the left side wall portion 44b. The missing portion 50 is open downward. The missing portion 50 is open to the main body 2h side.

As shown in the pushed-in position and the retracted position in FIG. 5, the rear end portion of the operating lever 16 enters into the main body 2h. When the operating lever 16 is in the retracted position, the missing portion 50 enters inside the main body 2h (outer shell member 36). At the same time, when the operating lever 16 is in the retracted position, the constituent parts of the main body 2h enter into the missing portion 50. In other words, the missing portion 50 contributes to avoiding interference with the main body 2h. When the operating lever 16 is in the protruding position, the missing portion 50 comes out of the main body 2h. By providing the missing portion 50, the operating lever 16 is prevented from hitting a member within the main body 2h, and the movable range of the operating lever 16 is ensured. In other words, the movable range from the protruding position to the retracted position can be ensured while suppressing the protruding height of the operating lever 16 at the protruding position. This configuration contributes to downsizing of the water discharge stop device 2.

As shown in FIG. 6(d), the operating lever 16 has a slide engagement portion 52. As shown in FIG. The slide engagement portion 52 is provided at the rear end of the operating lever 16. The slide engagement portion 52 is slidably engaged with the shielding member S1. The slide engagement portion 52 is slidably engaged with a slide portion 74 (described later) of the shielding member S1. The slide engagement portion 52 projects rearward from the rear wall portion 46. The slide engagement portion 52 has a right engagement portion 52a and a left engagement portion 52b. The right engaging portion 52a is slidably engaged with one edge of the shielding member S1, and the left engaging portion 52b is slidably engaged with the other edge of the shielding member S1.

As shown in FIG. 6(d), the right engaging portion 52a includes a first portion 521a and a second portion 522a that curves from the first portion 521a and extends toward the left engaging portion 52b. The right engaging portion 52a constitutes a slide groove. The rear end surface 46a and the second portion 522a constitute the side surface of the slide groove, and the first portion 521a constitutes the bottom surface of the slide groove.

As shown in FIG. 6(d), the left engaging portion 52b includes a first portion 521b and a second portion 522b that curves from the first portion 521b and extends toward the right engaging portion 52a. The left engaging portion 52b constitutes a slide groove. The rear end surface 46a and the second portion 522b constitute the side surface of the slide groove, and the first portion 521b constitutes the bottom surface of the slide groove.

As described above, the shielding member S1 is interlocked with the operating lever 16. When the operating lever 16 is in the protruding position, the shielding member S1 is in the first position P1. When the operating lever 16 is in the retracted position, the shielding member S1 is in the second position P2. Even when the operating lever 16 is in the pushed-in position, the shielding member S1 is in the second position P2. When the operating lever 16 is in the intermediate position, the shielding member S1 is located between the first position and the second position. The first position P1 is a position that protrudes more than the second position P2. The first position P1 is above the second position P2.

When the operating lever 16 is in the protruding position, the shielding member S1 does not protrude further than the operating lever 16. When the operating lever 16 is in the intermediate position, the shielding member S1 does not protrude beyond the operating lever 16. When the operating lever 16 is in the retracted position, the shielding member S1 does not protrude beyond the operating lever 16. The shielding member S1 does not get in the way when operating the operating lever 16. When the operating lever 16 is in the pushed-in position, the shielding member S1 protrudes (slightly) from the operating lever 16. However, the push-in position is reached in a short time when the operating lever 16 is operated. The protrusion of the shielding member S1 in the pushed-in position does not obstruct the operating lever 16. In the shielding member S1 that protrudes beyond the operating lever 16 in the pushed-in position and does not protrude further than the operating lever 16 in the retracted position, a width in the movement direction of the shielding member S1 is ensured within a range that does not interfere with the operation of the operating lever 16.

FIG. 7(a) is a perspective view of the shielding member S1, FIG. 7(b) is a side view of the shielding member S1, FIG. 7(c) is a rear view of the shielding member S1, and FIG. 7(d) is a perspective view of the shielding member S1. It is a front view of shielding member S1.

The shielding member S1 has an upper part 60 and a lower part 62. The upper portion 60 has a shielding portion 64 and an interlocking engagement portion 66 . The interlocking engagement portion 66 is a downward facing surface (stepped surface). The interlocking engagement portion 66 is formed by narrowing the width of the shielding member S1. The interlocking engagement portion 66 engages with the operating lever 16 when the operating lever 16 reaches a predetermined rotational position, and is pulled up by the operating lever 16 when the operating lever 16 rotates in the projecting direction. The lower portion 62 has extensions 68 on both sides. One end (lower end) of both side extending portions 68 is a free end. The both-side extending portions 68 have locking portions 70 . The locking portion 70 is provided at the end on the free end side. The both-side extending portion 68 has a right extending portion 68a and a left extending portion 68b. Each of the right extending portion 68a and the left extending portion 68b has a locking portion 70. A shielding missing portion 72 in which the shielding member S1 does not exist is formed between the right extending portion 68a and the left extending portion 68b. The shielding missing portion 72 is open to the main body 2h side. The shielding missing portion 72 is open downward. The both-side extending portions 68 extend on both sides of the shielding missing portion 72 . When the shielding member S1 is in the second position P2, the constituent parts of the main body 2h enter into the shielding missing portion 72. In other words, the shielding missing portion 72 prevents the shielding member S1 from interfering with the main body 2h. Although the both-side extending portions 68 are constituted by two extending portions, instead of this, the number of extending portions may be one, for example.

Due to the presence of the shielding missing portion 72, the both side extensions 68 are narrowed. Each of the extensions 68a and 68b may be provided with a small portion T1 having a cross-sectional area of 5 mm ² or less. This cross-sectional area and length measurement defines the reference state of the shielding member S1. As shown in FIGS. 7(b) and 7(c), when the shielding member S1 is placed on the horizontal plane PL, the height H of the shielding member S1 from the horizontal plane PL reaches the maximum value H1. The posture of the member S1 is set as a reference state. The cross-sectional area of the fine portion T1 is measured in the cross section along the plane PL1 parallel to the horizontal plane PL in the shielding member S1 in the standard state.The length of the fine portion T1 is Measured along a vertical line. The heights H and H1 are also measured along a line perpendicular to the horizontal plane PL. The length H2 of the extending portions 68a and 68b may be 13 mm or more and 19 mm or less, and more preferably 15 mm or more and 17 mm or less. This length H2 is measured along a line perpendicular to the horizontal plane PL in the shielding member S1 in the reference state. The ratio of the length of the fine portion T1 to the length H2 may be 40% or more and 100% or less, further 50% or more and 90% or less. The ratio (H2/H1) may be 0.3 or more and 0.7 or less, and further 0.4 or more and 0.6 or less. From the viewpoint of strength, the cross-sectional area of the small portion T1 may be 3 mm ² or more. One end (lower end) of the both-side extending portion 68 is a free end. The both-side extension portions 68 have a structure that is easily deformed.

As shown in FIG. 4A, the main body 2h has a main body engaging portion 76 that can engage with the locking portion 70. As shown in FIG. When the shielding member S1 moves in the protruding direction (upper side) from the first position, the locking portion 70 engages (catches) with the main body engaging portion 76. Therefore, further upward movement of the shielding member S1 is restricted.

The shielding member S1 has a sliding portion 74. The slide portion 74 is provided from the upper portion 60 to the lower portion 62. The slide portions 74 are provided at one edge and the other edge of the shielding member S1. The slide portion 74 is slidably engaged with the slide engagement portion 52. This sliding engagement is a concave-convex engagement between the slide groove and the slide rail. In this embodiment, the slide engagement portion 52 has a slide groove, and the slide portion 74 has a slide rail. The slide portion 74 has a right slide portion 74a and a left slide portion 74b. The right sliding portion 74a is slidably engaged with the right engaging portion 52a. The left sliding portion 74b is slidably engaged with the left engaging portion 52b.

FIGS. 8(a) and 8(b) are perspective views of the vicinity of the operating lever 16 when the shielding member S1 is in the protruding position. However, in FIG. 8(a), the shielding member S1 is removed. FIG. 8(a) is a virtual diagram showing the effect of the shielding member S1. As shown in FIG. 8A, when there is no shielding member S1, an opening 80 is formed at the rear end of the operating lever 16. The opening 80 is formed due to the missing portion 50. As described above, the missing portion 50 contributes to downsizing the water discharge stop device 2 and ensuring the movable range of the operating lever 16, but on the other hand, it can form the opening 80.

The opening 80 allows the inside and outside of the water discharge device 2 to communicate with each other. Foreign matter or the like may enter the water stop device 2 through the opening 80. Further, if a finger or the like enters the opening 80 or gets caught on the edge of the opening 80, the operability may deteriorate. As shown in FIG. 8(b), in this embodiment, since the shielding member S1 is provided, the opening 80 is not formed. The shielding member S1 may partially cover the opening 80. Preferably, the shielding member S1 covers the entire opening 80. In this embodiment, the shielding member S1 covers the entire opening 80. The operating lever 16 has an opening forming part 82 that can form an opening 80 open to the outside in the protruding position, and the shielding member S1 covers the opening forming part 82 in the operating lever 16 in the protruding position. In this embodiment, this opening forming portion 82 is the missing portion 50.

FIG. 9 is a side view showing the operating lever 16 and the shielding member S1 that slide into engagement with each other, and is a diagram showing the movement of the operating lever 16 and the shielding member S1. Note that in FIG. 9, the shielding member S1 and the slide engagement portion 52 are shown in cross section at the slide engagement position.

The movement of the operating lever 16 is rotation. The center of this rotation is the rotation center C1. The rotation center C1 is the center line of the rotation axis z16 mentioned above.

The shielding member S1 is slidably engaged with the operating lever 16. Except for this sliding engagement, the movement of the shielding member S1 is not restricted. When the operating lever 16 is rotated in the projecting direction, the slide engagement portion 52 comes into contact with the interlocking engagement portion 66 (see the upper diagram in FIG. 9). When the operating lever 16 is further rotated in the projecting direction, the shielding member S1 is pulled up by the operating lever 16. When the operating lever 16 is rotated in the retraction direction, the shielding member S1 moves in the retraction direction due to gravity, and the lower end of the shielding member S1 comes into contact with an adjacent member to reach the lower limit position. When the operating lever 16 is further rotated in the retraction direction, the engagement between the slide engaging portion 52 and the interlocking engaging portion 66 is released (see the lower diagram in FIG. 9). In this way, when the shielding member S1 is not in contact with the slide engaging portion 52, it is in a state where it can slide due to the gravity acting on the shielding member S1. The driving force behind the regression (downward movement) of the shielding member S1 is gravity.

When the slide engagement portion 52 is in contact with the interlocking engagement portion 66, the positional relationship between the operating lever 16 and the shielding member S1 is fixed. In this positional relationship, the shielding portion 64 of the shielding member S1 covers the missing portion 50 of the operating lever 16 (see FIGS. 8(a) and 8(b)). When the operation lever 16 is in the protruding position, the slide engagement portion 52 is maintained in contact with the interlocking engagement portion 66, and the shielding member S1 (shielding portion 64) covers the missing portion 50 of the operation lever 16.

FIG. 10 is a side view of the operating lever 16 and the shielding member S1. Only the rear end of the operating lever 16 is shown.

The operating lever 16 and the shielding member S1 have a sliding surface 90. When the shielding member S1 slides, the operating lever 16 and the shielding member S1 slide against each other on the sliding surface 90. The sliding surface 90 includes a sliding surface 92 and a sliding surface 94. The sliding surface 92 of the operating lever 16 is located on the rear end surface 46a. The sliding surface 94 of the shielding member S1 is located on the front surface (the surface on the operating lever 16 side) of the shielding member S1. Further, the contact surface between the slide engagement portion 52 and the slide portion 74 is also a sliding surface 90.

The sliding surface 92 of the operating lever 16 and the sliding surface 94 of the shielding member S1 are both curved surfaces that are convex toward the rear side. The sliding surface 92 of the operating lever 16 has a constant radius of curvature Rc. This radius of curvature R1 is equal to the distance from the rotation center C1 to the rear end surface 46a. The sliding surface 92 is a curved surface along a circle centered on the rotation center R1. On the other hand, the radius of curvature of the sliding surface 94 of the shielding member S1 is not constant. The sliding surface 94 has a first radius of curvature R1 and a second radius of curvature R2. The area with the radius of curvature R1 is located above the area with the radius of curvature R2. The first radius of curvature R1 is equal to the radius of curvature Rc of the sliding surface 92. The area with the radius of curvature R1 is along the sliding surface 92. The second radius of curvature R2 is smaller than the first radius of curvature R1. The area with the radius of curvature R2 does not lie along the sliding surface 92.

Thus, in the sliding surface 90, there is a mismatch in the radius of curvature between the radius of curvature Rc of the sliding surface 92 and the radius of curvature R2 of the sliding surface 94. The radius of curvature of a portion of the sliding surface 90 is made to be inconsistent. This discrepancy causes an imbalance in contact force (normal force) in the rotation range of the operating lever 16. As a result, when the portion with the radius of curvature Rc slides on the portion with the radius of curvature R2, the frictional force increases. By changing the radius of curvature, the frictional force increases in a part of the rotation range of the operating lever 16. This discrepancy in the radius of curvature is a frictional force increasing means that increases the frictional force between the operating lever 16 and the shielding member S1.

11(a) is a perspective view of the outer shell member 36, FIG. 11(b) is a side view of the outer shell member 36, and FIG. 11(c) is a front view of the outer shell member 36. The outer shell member 36 is integral as a whole. The outer shell member 36 forms the outer surface of the main body 2h. As shown in FIG. 3(b), an on-off valve V1 and a main flow path WP1 are arranged inside the outer shell member 36.

As shown in FIG. 11(b), the tubular portion 100 includes a front tubular portion 100a located in front of the window portion 102 and a rear tubular portion 100b located behind the window portion 102. The cross-sectional shape of the tubular portion 100 is not limited. The cross-sectional shape of the inner surface of the tubular portion 100 may or may not be a circle. The cross-sectional shape of the outer surface of the tubular portion 100 may or may not be a circle. In this embodiment, the tubular portion 100 is a cylinder. In this embodiment, the cross-sectional shape of the outer surface of the tubular portion 100 is a circle. The cross-sectional shape of the inner surface of the tubular portion 100 is circular except for partial protrusions (see FIG. 11(c)).

As shown in FIG. 11(b), the length L12 of the tubular portion 100 is greater than the length L3 of the window portion 102. In this embodiment, the length L12 of the tubular portion 100 is the sum of the length L1 of the front tubular portion 100a and the length L2 of the rear tubular portion 100b. The length L2 of the rear tubular portion 100b is greater than the length L3 of the window portion 102. The length L3 of the window portion 102 is smaller than half the length L4 of the outer shell member 36. These lengths are measured along the longitudinal direction of the outer shell member 36 (the axial direction of the tubular portion 100).

The outer shell member 36 is integrally molded as a whole. The outer shell member 36 has an integral structure as a whole.

The window portion 102 is an opening that allows communication between the outside and the inside (hollow portion) of the outer shell member 36. In the longitudinal direction of the outer shell member 36, the portion where the window portion 102 is present is not a tubular portion as referred to in the present application. The front tubular portion 100a and the rear tubular portion 100b are connected through a non-opening portion 104. The inner and outer surfaces of the non-opening portion 104 have the same cross-sectional shape as the front tubular portion 100a and the rear tubular portion 100b.

The operating lever 16 and the shielding member S1 are arranged in the window part 102. When the operating lever 16 is in the protruding position, the operating lever 16 and the shielding member S1 protrude from the window portion 102. The operating lever 16 rotates within the window portion 102 in the protruding direction and the retracting direction. The operating lever 16 and the shielding member S1 move in and out of the window 102. The shielding member S1 is interlocked with the operating lever 16 within the window portion 102.

12(a) is a perspective view of the assembled unit 110, FIG. 12(b) is a side view of the assembled unit 110, and FIG. 12(c) is a front view of the assembled unit 110. Assembly unit 110 has a main portion 110a and an end portion 110b. End portion 110b constitutes a front end portion of assembled unit 110. The portion on the rear side of the end portion 110b is the main portion 110a. The main portion 110a is also the main portion of the main body 2h.

The assembled unit 110 is formed by assembling members arranged inside the outer shell member 36. The main portion 110a includes an on-off valve V1. The main portion 110a includes a flow path forming portion that forms the main flow path WP1. The main portion 110a includes a link member 30. Main portion 110a includes a rotation axis z16. Main portion 110a includes pin 24 of alternate mechanism 18. The main portion 110a includes all the members disposed inside the outer shell member 36.

As can be understood from FIG. 12(c), the main portion 110a of the assembled unit 110 has a shape that can be inserted into the inside of a cylinder. Note that in FIGS. 12(a) to 12(c), the link member 30 is in a folded state.

FIG. 13 is a process diagram showing the process of attaching the outer shell member 36 to the assembly unit 110. The main portion 110a of the assembled unit 110 is inserted into the inside of the outer shell member 36 through the opening 36a at the end of the outer shell member 36. The opening 36a is an opening at the end of the tubular portion 100. Main portion 110a is inserted into outer shell member 36 through opening 36a. This insertion forms the assembly 120. The operating lever 16 and the shielding member S1 are attached to the assembly 120. The operating lever 16 and the shielding member S1 are attached to the main portion 110a from the outside of the outer shell member 36. The operating lever 16 and the shielding member S1 are assembled through the window portion 102. Assembly of the operating lever 16 is completed by fitting the rotation support part 40 onto the rotating shaft z16 and fitting the first end 30a of the link member 30 into the slide groove on the inner surface of the upper wall part 42. In addition, the shielding member S1 is assembled by elastically deforming the right extending portion 68a and the left extending portion 68b so that the right extending portion 68a and the left extending portion 68b approach each other, and then moving the both side extending portions 68 to the slide engaging portion 52 of the operating lever 16 (right engaging portion 52a). and the left engaging part 52b), and the locking part 70 is completed by reaching the lower side of the main body engaging part 76.

In this manner, the operating lever 16 is assembled from the outside of the outer shell member 36 to the main portion 110a located inside the outer shell member 36. Further, the shielding member S1 is assembled from the outside of the outer shell member 36. The main portion 110a can be inserted from the end of the outer shell member 36. For assembly, there is no need to divide the outer shell member 36 or provide a notch in the outer shell member 36. The outer shell member 36 is an integral member including the tubular portion 100.

[Second embodiment]
14(a) and 14(b) are perspective views of a water discharge stop device 200 according to the second embodiment. FIG. 15(a) is a sectional view of FIG. 14(a) in the vicinity of the operating lever. FIG. 15(b) is a sectional view of FIG. 14(b) in the vicinity of the operating lever. In FIGS. 14(a) and 15(a), the operating lever 16 is in the protruding position. In FIGS. 14(b) and 15(b), the operating lever 16 is in the retracted position.

The water discharge device 200 includes a multistage shielding member S1 and an operating lever 16. The water discharge device 200 is the same as the water discharge device 2 except that the shielding member S1 is of a multi-stage type and the slide engagement portion of the operating lever 16 has a form corresponding to the shielding member S1.

There are a plurality of shielding members S1. The water discharge device 200 includes a first shielding member S11, a second shielding member S12, and a third shielding member S13. The plurality of shielding members S11 to S13 are arranged adjacent to the rear end surface of the operating lever 16. The plurality of shielding members S11 to S13 are arranged in an overlapping state.

In the water discharge device 200, the number of shielding members S1 is three. The number of shielding members S1 may be two, or the number of shielding members S1 may be four or more. Considering the number of parts and the ease of assembly, the number of shielding members S1 is preferably 6 or less, more preferably 5 or less, and even more preferably 4 or less.

The shielding member S1 is interlocked with the operating lever 16. When the operating lever 16 is in the protruding position, the shielding member S1 is in the first position. This first position is a position where the protruding heights of the plurality of shielding members S11 to S13 are changed in stages. As shown in FIG. 15(a), in this first position, the closer the shielding member is to the operating lever 16, the greater the protruding height. In other words, in this first position, the shielding member closer to the operating lever 16 is located at a higher position. In order to achieve this positional relationship, the operating lever 16 has a plurality of slide engagement portions 52 whose upper end positions change in stages (see FIG. 14(a)). The first sliding engagement portion 52x is in sliding engagement with the first shielding member S11. The second sliding engagement portion 52y is in sliding engagement with the second shielding member S12. The third slide engagement portion 52z is slidably engaged with the third shielding member S13. The upper end of the first slide engagement part 52x is located above the upper end of the second slide engagement part 52y. The upper end of the second slide engagement portion 52y is located above the upper end of the third slide engagement portion 52z. Similar to the first embodiment, the shielding member S1 is pulled up by the operating lever 16 and lowered by the force of gravity acting on the shielding member S1.

As shown in FIG. 15(a), when the operating lever 16 is in the protruding position, the missing portion 50 of the operating lever 16 is covered by a plurality of shielding members S11 to S13. The missing portion 50 is covered by a plurality of shielding members S11 to S13 that are arranged in stages with their positions shifted in the protruding direction. As shown in FIG. 15(b), when the operating lever 16 is in the retracted position, the plurality of shielding members S11 to S13 are in the second position. When the operating lever 16 is in the retracted position, the plurality of shielding members S11 to S13 are located at the lower limit of their movable range. In each of the plurality of shielding members S11 to S13, the protrusion height at the second position is lower than the protrusion height at the first position. The protruding heights of all the shielding members S11 to S13 at the second position are lower than the protruding height at the first position of the shielding member S13, which has the lowest protruding height at the first position. As shown in FIG. 15(b), when the operating lever 16 is in the retracted position, the protruding heights of the plurality of shielding members S11 to S13 are the same. When the operating lever 16 is in the retracted position, the protruding heights of the plurality of shielding members S11 to S13 are lower than the protruding height of the operating lever 16.

In this multistage shielding member S1, the vertical width of each shielding member S11 to S13 can be reduced. The multistage shielding member S1 contributes to miniaturization of the water discharge stop device 200.

[First state and second state of shielding member S1]
In the first and second embodiments described above, the interlocking movement of the shielding member S1 is sliding movement. In these embodiments, the position of the shielding member S1 changes in conjunction with the operating lever 16. The positions of this shielding member S1 include a first position P1 and a second position P2. The change in the shielding member S1 in conjunction with the operating lever 16 is not limited to a change in position. By interlocking with the operating lever 16, the shielding member S1 is configured to take a first state when the operating lever 16 is in the protruding position and a second state when the operating lever 16 is in the retracted position. . The first position P1 is an example of the first state. The second position P2 is an example of the second state. In the first state, the shielding member S1 covers the missing portion 50. In the second state, the protruding height of the shielding member S1 is lower than in the first state. The protruding height is the height from the outer surface of the main body 2h. This height can be measured along the normal direction of the outer surface (gripping surface 6a) of the main body 2h.

The shielding member S1 does not have to slide. The shielding member S1 may be, for example, an expandable member. That is, the shielding member S1 may expand and contract in conjunction with the operating lever 16. Examples of the expandable and contractible shielding member S1 include a bellows member having a bellows structure, a rubber sheet, and a waterproof sheet. The material of the bellows member may be, for example, nonwoven fabric. In the shielding member S1 that expands and contracts, the extended state is the first state, and the contracted state is the second state. For example, interlocking with the operating lever 16 can be achieved by fixing one end of the telescopic member to the operating lever 16 and fixing the other end to the main body 2h.

[Effect]
The embodiment described above has the following effects.

[Aperture shielding]
The shielding member S1 can minimize the opening (gap) between the operating lever 16 and the main body 2h that may occur at the protruding position. Therefore, the intrusion of foreign matter is suppressed. Furthermore, fingers are prevented from entering the opening, improving operability.

Since the opening is hidden, the operating lever 16 can be provided with a cutout 50 that creates the opening. The missing portion 50 prevents the operating lever 16 from coming into contact with (interfering with) the main body 2h. Therefore, while reducing the size of the water discharge stop device 2 in the movable direction of the operating lever 16, the stroke of the operating lever 16 can be increased, and the length of the operating lever 16 from the rotation center C1 can also be increased. As a result, the operating force can be reduced and the operability is improved.

The water discharge stop device 2 may be dragged. For example, the user may hold only the hose and drag the water discharge stop device 2. In this case, if the opening is present, the opening may get caught on the protrusion and the water discharge stop device 2 may be damaged. Hiding the opening may prevent such damage.

[Accommodation of shielding member S1]
Since the shielding member S1 is lowered when the operating lever 16 is in the retracted position, the shielding member S1 is prevented from becoming a hindrance during operation of the operating lever 16. This improves operability.

When a multistage system is used using a plurality of shielding members S1, the movable range per one shielding member can be reduced. Furthermore, the concealment range shared by one shielding member can be reduced. Therefore, the width in the movable direction of each shielding member S1 can be reduced. In the multi-stage type, further miniaturization of the water discharge stop device 2 in the movable direction is possible.

Since the shielding member S1 is provided with the shielding missing portion 72, the protruding height of the shielding member S1 when the operating lever 16 is in the retracted position can be reduced. Therefore, the shielding member S1 is prevented from becoming an obstacle when operating the operating lever 16, and operability is improved. Moreover, the water discharge stop device 2 can be downsized in the movable direction of the shielding member S1.

[Preventing the operating lever 16 from falling off]
The shielding member S1 has a locking portion 70. When the shielding member S1 moves in the protruding direction from the first position, the locking part 70 engages with the main body engaging part 76 (see (a) in FIG. 4). Therefore, movement of the shielding member S1 in the protruding direction is restricted, and rotation of the operating lever 16 in the protruding direction is also restricted. Further, when the locking portion 70 is engaged with the main body engaging portion 76, the shielding member S1 is engaged with the operating lever 16. Therefore, the engagement of the locking portion 70 with the main body engaging portion 76 prevents the operating lever 16 from falling off.

[Ease of assembly]
As shown in FIG. 7(c), the shielding member S1 has extending portions 68 on both sides. The both-side extending portions 68 are narrowed by the shielding missing portions 72 and are easily deformed. The operating lever 16 and the shielding member S1 can be assembled from the outside of the outer shell member 36. Further, the operating lever 16 and the shielding member S1 can be assembled through the window portion 102 of the outer shell member 36. The window portion 102 is an essential opening for protruding the operating lever 16 and the shielding member S1. The operating lever 16 and the shielding member S1 can be assembled through the window 102, and it is not necessary to provide a split structure, a cutout, etc. in the outer shell member 36 for the assembly. Further, a portion (main portion 110a) of the main body 2h disposed inside the outer shell member 36 can be inserted into the outer shell member 36 in an assembled state. In this way, the water discharge stop device 2 is easy to assemble.

The locking portion 70 of the shielding member S1 contributes to ease of assembly. The locking portion 70 is provided on the both-side extending portions 68. Since the both-side extending portions 68 have a shape that is easily deformed, it is easy to insert the both-side extending portions 68 including the locking portions 70 through the window portion 102 and assemble them into the main portion 110a. A structure in which the locking portion 70 prevents the operating lever 16 from falling off can be realized by assembling it from the outside through the window portion 102.

[Improvement of rigidity of gripping part 6]
In the embodiment described above, the outer shell member 36 is used. This outer shell member 36 forms a gripping surface 6a of the gripping portion 6. The main portion 110a is comprised of an opening 36a at the end of the tubular portion 100 of the outer shell member 36. Therefore, in order to assemble the main portion 110a, there is no need to divide the outer shell member 36 or provide a notch in the outer shell member 36. Further, the operating lever 16 and the shielding member S1 can be assembled to the main portion 110a through the window portion 102. Therefore, in order to assemble the operating lever 16 and the shielding member S1, there is no need to divide the outer shell member 36 or provide a notch in the outer shell member 36. Therefore, the outer shell member 36 can be made into an integral member, and the rigidity of the outer shell member 36 can be increased.

Since the outer shell member 36 is an integral member including the tubular portion 100, it has high structural rigidity. For example, when the water stop device 2 is made longer or a brush is attached to the tip of the water stop device 2, a large force is applied to the grip portion 6. By increasing the rigidity of the outer shell member 36, the rigidity of the grip portion 6 can be increased, and the operability of the water stop device 2 is improved.

The rigidity of the grip portion 6 can also be improved by increasing the rigidity of the main portion 110a, which is an internal member. However, it is structurally more efficient to increase the rigidity of the outer shell member 36, and the dependence on the material can be reduced.

[Prevention of rattling and popping out of shielding member S1]
As described above, the shielding member S1 is in a state of being lowered by gravity. When the shielding member S1 can freely move up and down, vibration may occur in the water discharge stop device 2 during water discharge, etc., and rattling may occur. Further, depending on the posture, operation, etc. of the water discharge stop device 2, the shielding member S1 may pop out. The above-mentioned frictional force increasing means can prevent rattling and popping out.

In the above embodiment, the region with the second radius of curvature R2 is located below the region with the first radius of curvature R1. The frictional force increasing means is activated when the operating lever 16 is in the retracted position, and is not activated when the operating lever 16 is in the extended position. That is, regarding the movement resistance when the shielding member S1 slides, the movement resistance when the operating lever 16 is in the retracted position is greater than the movement resistance when the operating lever 16 is in the protruding position. When the operating lever 16 is in the retracted position, if the shielding member S1 pops out, it tends to get in the way. In the above embodiment, when the operating lever 16 is in the retracted position, the shaking and protrusion of the shielding member S1 can be effectively suppressed.

From the viewpoint of preventing rattling and the like, the present invention is not limited to the frictional force increasing means. Preferably, a resistance increasing means is provided for increasing the movement resistance of the sliding movement of the shielding member S1. The frictional force increasing means is an example of a resistance increasing means.

Examples of resistance increasing means other than frictional force increasing means include the following.
(1) A magnetic force means is provided to attract the shielding member S1 to the operating lever 16 by magnetic force. For example, a magnetic material (such as a magnet) may be provided on the shielding member S1 and/or the operating lever 16. For example, a sheet-like magnetic material may be used.
(2) A magnetic force means is provided to attract the shielding member S1 to the main body 2h by magnetic force. For example, a magnetic material (such as a magnet) is provided on the shielding member S1 and/or the main body 2h. For example, a sheet-like magnetic material may be used.
(3) Connect the shielding member S1 and the operating lever 16 with an elastic body (such as a spring).
(4) Connect the shielding member S1 and the main body 2h with an elastic body (such as a spring).

Moreover, the following are exemplified as the frictional force increasing means. The above embodiment is an example of (1) below.
(1) The sliding surface 92 of the operating lever 16 and/or the sliding surface 94 of the shielding member S1 have a contact pressure changing shape. The contact pressure changing shape is a shape that changes the contact pressure between the sliding surfaces 92 and 94 within the movable range of the operating lever 16. An example of the contact pressure changing shape is a shape in which the radius of curvature of the sliding surface is changed as in the above embodiment. Another example of a contact pressure changing shape is a shape in which a sliding surface is provided with a step.
(2) The sliding surface 92 of the operating lever 16 and/or the sliding surface 94 of the shielding member S1 have a friction coefficient changing portion. The friction coefficient changing section can be configured by changing the surface roughness, for example.
(3) The shielding member S1 has a pressing portion that presses the operating lever 16 while being elastically deformed.
(4) The operating lever 16 has a pressing portion that presses the shielding member S1 while being elastically deformed.
(5) The shielding member S1 has a pressing portion that presses the main body 2h while being elastically deformed.

As mentioned above, when the operating lever 16 is in the retracted position, the shaking and protrusion of the shielding member S1 are particularly problematic. On the other hand, from the viewpoint of operability, the lower the operating resistance of the operating lever 16, the better. From these viewpoints, it is preferable that the sliding resistance of the shielding member S1 when the operating lever 16 is in the retracted position is greater than the sliding resistance of the shielding member S1 when the operating lever 16 is in the protruding position. Preferably, the resistance increasing means is configured to create such a difference in sliding resistance. It is preferable that the resistance increasing means be expressed in a part of the movable range of the operating lever 16.

Examples of the material of the shielding member S1 include resin and metal. Resin is preferred from the viewpoint of elastic deformation during assembly. Considering the viewpoint of preventing the operating lever from falling off, a resin with toughness is preferable. Furthermore, from the viewpoint of ease of molding, thermoplastic resins are preferred. From these viewpoints, POM (polyacetal) is preferred.

The operating lever 16 is not required to have as much strength and toughness as the shielding member S1. As the material for the operating lever, resin is preferable, and thermoplastic resin, which is easy to mold, is more preferable. Considering cost, PP (polypropylene) and ABS (acrylonitrile butadiene styrene copolymer synthetic resin) are preferred.

The material of the outer shell member 36 can be selected depending on appearance, strength, rigidity, etc. Instead of a member that requires elastic deformation, a highly rigid material may be used, such as resin or metal. Resin is preferable from the viewpoint of achieving both appearance and strength and from the viewpoint of mass production of three-dimensional shapes. Preferred resins include fiber reinforced resins and super engineering plastics. Among the fiber-reinforced resins, glass fiber-reinforced resins are preferred, and glass fiber-reinforced ABS resins are more preferred. An example of a super engineering plastic is polyphenylene sulfide (PPS). In the examples, glass fiber reinforced ABS resin was used.

Examples of the material of the member (flow path forming portion) forming the main flow path WP1 in the main body 2h include resin and metal. In terms of pressure resistance and corrosion resistance, stainless steel is preferable among metals. As for the resin, thermoplastic resins that are easy to mold are preferred, and ABS (acrylonitrile butadiene styrene copolymer synthetic resin) and POM (polyacetal) are more preferred. ABS was used in the example.
