Description

[Technical Field]

[0001] The present invention relates to a faucet operating device, specifically, a faucet operating device having an operating shaft to which a rotary operating member is attached, a housing through which the operating shaft passes in the axial direction, and a click mechanism that imparts a clicking sensation when the operating shaft is rotated relative to the housing. [Background technology]

[0002] Patent Document 1 discloses a faucet operating device equipped with a click mechanism that imparts a clicking sensation to the rotation of a switch handle. The click mechanism is configured to impart a clicking sensation by elastically fitting a protrusion of a leaf spring provided on one of two members that rotate relative to each other when the switch handle is operated into a groove formed on the other member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7027123 Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration described in Patent Document 1, the leaf spring itself slides in the rotational direction while fitting into and removing from the groove. This creates the problem that the leaf spring is prone to wear and settling over long-term use. Therefore, the present invention provides a faucet operating device in which the click mechanism is less susceptible to wear and deterioration. [Means for solving the problem]

[0005] In order to solve the above problems, the water faucet operating device of the present invention takes the following measures.

[0006] In other words, the first invention of the present invention is a faucet operating device having an operating shaft to which a rotary operating member is attached, a housing through which the operating shaft passes axially, and a click mechanism that imparts a clicking sensation to the operation of rotating the operating shaft relative to the housing, wherein the click mechanism has a guide that is arranged so as to be integral with the operating shaft in the rotational direction, a movable part that is supported on both sides of the rotational direction so as to be able to slide radially relative to the guide, an elastic member that applies a spring force to push the movable part radially outward relative to the guide, and an engaging part that is arranged so as to be integral with the housing and has engaging grooves at multiple locations in the rotational direction into which the movable part pushed out by the elastic member engages from the radially inner side, and the movable part is engaged and disengaged with respect to the multiple engaging grooves by the spring force of the elastic member as the operating shaft rotates, thereby imparting the clicking sensation.

[0007] According to the first aspect of the present invention, by separating the movable part from the elastic member, the movable part that slides with the fitting groove can be made of a hard material that is resistant to wear, while the elastic member that does not slide with the fitting groove can be made of a soft material that is highly elastic. Therefore, the click mechanism can be configured to be resistant to wear and deterioration and to provide a stable clicking operation. The click mechanism pushes the movable part radially outward to fit into the fitting part, so that an appropriate amount of elastic force is applied to the movable part to perform the clicking operation without applying an axial load to the operating shaft or guide. Furthermore, because the fitting groove is formed at a position radially spaced from the axial center, the fitting groove can be configured to have a high structural strength that can exert high resistance.

[0008] A second aspect of the present invention is a faucet operating device according to the first aspect, wherein the plurality of fitting grooves are arranged in a sawtooth pattern in the rotational direction along the inner circumferential surface of the fitting portion.

[0009] According to the second invention, it is possible to impart a clicking sensation at regular intervals to the rotation of the operating shaft.

[0010] A third aspect of the present invention is the faucet operating device according to the second aspect, wherein the movable parts are provided at a plurality of positions in the rotation direction of the guide.

[0011] According to the third invention, the mechanism that causes the movable part to perform a clicking operation is distributed to multiple locations in the rotational direction, making it possible to obtain a clicking sensation of appropriate strength without making the elastic force of each part too strong.

[0012] A fourth invention of the present invention is a faucet operating device in which, in any of the first to third inventions above, the elastic member is a rubber O-ring that is mounted in a mounting groove that is annularly recessed around the axis of the operating shaft and formed on the outer periphery of the guide.

[0013] According to the fourth aspect of the present invention, the elastic member can be simply and appropriately fixed to the guide. Furthermore, by using rubber for the elastic member, it is possible to reduce the reverberation that occurs when the movable part fits into the fitting groove. This reduces the reverberation of the clicking sound and improves the texture of the clicking sound.

[0014] A fifth aspect of the present invention is a faucet operating device according to any one of the first to third aspects, wherein the movable part is made of a round rod-shaped pin extending in the axial direction.

[0015] According to the fifth aspect of the present invention, the movable portion can be fitted into the fitting groove so as to be in line contact with the fitting groove, thereby improving load distribution compared to a configuration in which these are in point contact.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0018] First Embodiment (Schematic configuration of the faucet operating device) First, the configuration of a faucet operating device according to a first embodiment of the present invention will be described with reference to Figures 1 to 6. In the following description, when directions such as front, back, top, bottom, left, and right are indicated, they refer to the directions shown in each figure.

[0019] The directions shown in each figure are those seen from the front of a mixer faucet 1 to which the faucet operating device according to this embodiment is applied. In the following description, when no specific reference figure is shown or when no reference figure has a corresponding symbol, reference will be made to any of Figures 1 to 6 as appropriate.

[0020] As shown in Figure 1, the faucet operating device according to this embodiment is configured as a hot and cold water mixing valve 10 incorporated into a wall-mounted mixer faucet 1 that is installed on the wall of a bathroom. The mixer faucet 1 has the function of mixing hot and cold water supplied from the back side of the bathroom wall and discharging the mixed water.

[0021] Specifically, the mixer faucet 1 is configured so that the mixing ratio of hot and cold water supplied to the faucet body 2 can be adjusted internally by operating a substantially cylindrical temperature adjustment handle 3 attached to the left side of the faucet body 2. In addition, the mixer faucet 1 is configured so that the mixed hot and cold water can be switched on and off and the amount of hot and cold water discharged can be adjusted by operating a substantially cylindrical switching handle 4 attached to the right side of the faucet body 2.

[0022] More specifically, when the user turns the temperature adjustment handle 3 to the desired rotation position, the ratio of hot and cold water mixed inside the faucet body 2 is adjusted to the set temperature corresponding to the rotation position. Also, when the user turns the switch handle 4 upward from a predetermined water stop position (position shown), an amount of hot and cold water corresponding to the amount of rotation is discharged from the shower elbow 5 connected to the flow path on the back surface of the faucet body 2 to a shower head (not shown).

[0023] Furthermore, when the user turns the switch handle 4 downward from a predetermined water stop position (position shown), an amount of hot and cold water corresponding to the amount of rotation is discharged from the faucet 6 connected to the flow path on the underside of the faucet body 2. The above-mentioned adjustment of the hot and cold water mixing ratio and switching between water discharge and water stop are performed by the hot and cold water mixing valve 10 (thermo cartridge) built into the faucet body 2.

[0024] The hot and cold water mixing valve 10 consists of a roughly cylindrical assembly that extends in the left-right direction. A temperature adjustment handle 3 is attached to the left end of the hot and cold water mixing valve 10. A switching valve (not shown) is connected to the right end of the hot and cold water mixing valve 10 via a flow path. A switching handle 4 is attached to the right end of this switching valve (not shown). When the temperature adjustment handle 3 is turned, the hot and cold water mixing valve 10 operates an internal valve mechanism (not shown), which adjusts the mixing ratio of the hot and cold water taken in.

[0025] Furthermore, when the switching handle 4 is turned, a switching valve (not shown) is operated to switch between water discharge and water stop and adjust the discharge rate of hot and cold water whose mixing ratio has been adjusted in the hot and cold water mixing valve 10. The basic configuration of the hot and cold water mixing valve 10 is the same as the publicly known configuration disclosed in documents such as JP 2023-146082 A. Therefore, a detailed description of the basic configuration of the hot and cold water mixing valve 10 will be omitted.

[0026] The hot and cold water mixing valve 10 described above incorporates a click mechanism CL that can impart a clicking sensation at regular intervals to the rotation of the temperature adjustment handle 3. This click mechanism CL allows the user to feel the progress of the rotation operation at regular intervals through sound and tactile feedback when rotating the temperature adjustment handle 3. Here, the temperature adjustment handle 3 corresponds to the "operating member" of the present invention.

[0027] (Click mechanism CL) The specific configuration of the above-mentioned click mechanism CL will be described in detail below, along with the related structure of the hot and cold water mixing valve 10.

[0028] 2 to 4, the hot and cold water mixing valve 10 has an operating shaft 11 to which the temperature adjustment handle 3 is attached, and a cylindrical housing 12 through which the operating shaft 11 passes in the axial direction (left and right direction in the figure). The hot and cold water mixing valve 10 also has a ring-shaped cap 13 that covers the cylindrical end on the left side of the housing 12, and an E-ring 14 that is attached to the outer periphery of the operating shaft 11 that protrudes outward (left side) from the cap 13 to prevent it from coming off.

[0029] The operating shaft 11 is inserted into the cylindrical housing 12 from the right side and is assembled in a state in which movement to the left relative to the housing 12 is restricted. With this assembly, the operating shaft 11 is set so as to be rotatable around the axial center relative to the housing 12.

[0030] In this state, the cap 13 is passed over the operating shaft 11 from the left side, and an E-ring 14 is attached to the outer periphery of the operating shaft 11 adjacent to the outside of the cap 13 (see Figure 2). The cap 13 is shaped like a ring plate with approximately the same outer diameter as the outer periphery of the left cylindrical end of the housing 12.

[0031] The cap 13 is assembled to the operating shaft 11 so as to be integral with the operating shaft 11 in the rotational direction by fitting with the key 11A that protrudes from the outer periphery of the operating shaft 11. With this assembly, the operating shaft 11 is restricted from moving to the right relative to the housing 12 via the E-ring 14 and the cap 13.

[0032] 4, the click mechanism CL is provided between the operating shaft 11 and the housing 12. Specifically, the click mechanism CL has a ring-plate-shaped guide 15 attached to the operating shaft 11, and round bar-shaped pins 16 attached to eight locations in the rotational direction of the guide 15.

[0033] The click mechanism CL also has a rubber O-ring 17 that is fitted into an annular fitting groove 15C formed on the outer periphery of the guide 15. The click mechanism CL also has a cylindrical fitting portion 12B that forms the left cylindrical end of the housing 12 and has sawtooth fitting grooves B1 on its inner circumferential surface. Each fitting groove B1 is formed in the shape of a groove that extends in the axial direction, into which each pin 16 assembled to the guide 15 can be fitted from the radially inner side.

[0034] The guide 15 is passed through the operating shaft 11 from the left side and assembled to be integral with the operating shaft 11 in the rotational direction. Specifically, the guide 15 is assembled to be integral with the operating shaft 11 in the rotational direction by fitting a key groove 15A extending from a hole in the center of the guide 15 into a key 11A of the operating shaft 11.

[0035] Guide grooves 15B are formed on the outer periphery of the guide 15 at eight locations in the rotational direction, recessed radially inward toward the axial center of the guide 15. Each guide groove 15B is formed to penetrate the outer periphery of the guide 15 in the axial direction. Each guide groove 15B is formed to be aligned at equal intervals in the rotational direction on the outer periphery of the guide 15. Each guide groove 15B is formed to have the same groove shape.

[0036] Furthermore, a mounting groove 15C is formed in the outer periphery of the guide 15 in the middle portion excluding both axial ends, and extends in an annular shape around the axial center of the guide 15. The mounting groove 15C is formed in an annular shape passing through each guide groove 15B. The mounting groove 15C has a groove shape that is recessed more radially inward than each guide groove 15B.

[0037] A rubber O-ring 17 is fitted into the above-mentioned fitting groove 15C from the outer periphery. Also, a pin 16 is fitted into each guide groove 15B from the outer periphery. As a result, each pin 16 is set in a state where it is supported from both sides in the rotational direction relative to each guide groove 15B so as to be slidable in the radial direction.

[0038] Each pin 16 has an axial length that is slightly shorter than the thickness (axial length) of the guide 15 and is approximately the same. Each pin 16 is made of stainless steel, which is harder than the resin material that makes up the housing 12. Here, each pin 16 corresponds to the "movable part" of the present invention. Also, the O-ring 17 corresponds to the "elastic member" of the present invention.

[0039] 5, O-ring 17 attached to guide 15 has a wall thickness that protrudes into each guide groove 15B in its free state, so that O-ring 17 exerts a resilient force that pushes each pin 16 inserted through each guide groove 15B outward in the radial direction.

[0040] 6, the guide 15 is passed through the operating shaft 11 from the left side, and is set in a state where it is housed inside the cylindrical fitting portion 12B of the housing 12. Specifically, with the above assembly, the guide 15 is set in a state where it faces from the left side the bearing portion 12A that is formed on the inner periphery of the housing 12 and protrudes in a reduced diameter.

[0041] As a result, the guide 15 is set at a position where it overlaps with the fitting portion 12B in the axial direction, and as a result, each pin 16 assembled to the outer periphery of the guide 15 faces from the inside in the radial direction toward the inner circumferential surface on which each fitting groove B1 of the fitting portion 12B is formed.

[0042] After the cap 13 is inserted onto the operating shaft 11, the guide 15 is placed on the operating shaft 11 from the left side, so that the guide 15 is sandwiched in the axial direction between the cap 13 and the pivot support portion 12A of the housing 12. As a result, the guide 15 is held in a state where it does not shift axially relative to the operating shaft 11 by the retaining action of the E-ring 14 that is attached to the operating shaft 11 after the cap 13 is inserted.

[0043] The journal support portion 12A of the housing 12 functions as an axial direction restricting portion that restricts the axial insertion position when the operating shaft 11 is inserted from the right side into the cylindrical portion of the housing 12. Specifically, when the operating shaft 11 is passed through the journal support portion 12A from the right side, a flange 11B that protrudes in an expanded diameter and is formed in the axial middle portion of the operating shaft 11 comes into contact with the journal support portion 12A from the right side, restricting axial movement.

[0044] The shaft support portion 12A also functions as a rotation support portion that supports the operating shaft 11 inserted therein from the outer periphery so that the operating shaft 11 can rotate about its axis. Between the shaft support portion 12A and the cap 13, the guide 15 is held so as not to be displaced in the axial direction relative to the operating shaft 11.

[0045] By the above assembly, each pin 16 assembled to the guide 15 is pushed out so as to fit into each fitting groove B1 located radially outward of it by the elastic force applied by the O-ring 17. As a result, the fitting force between each pin 16 and each fitting groove B1 via the elastic force of the O-ring 17 applies a resistance force to the operating shaft 11 that restricts movement in the rotational direction.

[0046] This prevents the temperature control handle 3 attached to the operating shaft 11 from turning unintentionally. Because each pin 16 has a round bar shape extending in the axial direction, it makes line contact with each fitting groove B1 rather than point contact. This allows each pin 16 to widely distribute the pressing force that occurs when it comes into contact with each fitting groove B1 in the axial direction. As a result, the load caused by the sliding between each pin 16 and each fitting groove B1 is reduced, making each fitting groove B1 less likely to wear out.

[0047] When the temperature adjustment handle 3 is rotated from the above-described fitted state against the resilient force of the O-ring 17, the operating shaft 11 is rotated relative to the housing 12 while elastically removing the pins 16 from the fitting grooves B1. Then, as the operating shaft 11 rotates, the fitting grooves B1 are again aligned with the radially outer positions of the pins 16, and as the pins 16 fit into the fitting grooves B1 due to the resilient force of the O-ring 17, the operating shaft 11 receives a resistance force in the rotational direction accompanied by a clicking sensation.

[0048] Therefore, by ceasing operation of the temperature control handle 3 at such a position, the temperature control handle 3 can be stopped appropriately at a position at regular intervals where a clicking sensation is imparted. The fitting grooves B1 are formed so that they are continuously aligned at 9-degree intervals in the rotational direction. Each pin 16 is subjected to the same elastic force from the radially inner side by a single O-ring 17. As a result, each pin 16 fits into its corresponding fitting groove B1 simultaneously, imparting a high-quality clicking sensation.

[0049] Additionally, the elastic member that applies a resilient force to each pin 16 is made up of a rubber O-ring 17. As a result, the reverberation that occurs when each pin 16 fits into each fitting groove B1 can be reduced by the rubber O-ring 17. This suppresses the reverberation of the clicking sound and improves the texture of the clicking sound.

[0050] To summarize the above, the faucet operating device (hot water / cold water mixing valve 10) according to the first embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0051] That is, the faucet operating device (10) has an operating shaft (11) to which a rotary operating member (3) is attached, a housing (12) through which the operating shaft (11) passes in the axial direction, and a click mechanism (CL) that imparts a clicking sensation to the operation of turning the operating shaft (11) relative to the housing (12). The click mechanism (CL) has a guide (15) that is provided so as to be integral with the operating shaft (11) in the rotational direction, a movable part (16) that is supported from both sides in the rotational direction so as to be slidable radially relative to the guide (15), and an elastic member (17) that applies a spring force that pushes the movable part (16) radially outward relative to the guide (15).

[0052] The click mechanism (CL) also has a fitting portion (12B) that is provided integrally with the housing (12). The fitting portion (12B) has fitting grooves (B1) at multiple locations in the rotational direction, into which the movable portion (16) pushed out by the elastic member (17) fits from the radially inner side. As the operating shaft (11) rotates, the elastic force of the elastic member (17) causes the movable portion (16) to fit into and disengage from the multiple fitting grooves (B1) so as to provide a clicking sensation.

[0053] In this way, by configuring the movable part (16) separately from the elastic member (17), the movable part (16) that slides with the fitting groove (B1) can be configured from a hard material that is resistant to wear, while the elastic member (17) that does not slide with the fitting groove (B1) can be configured from a soft material that is highly elastic. Therefore, the click mechanism (CL) can be configured to be less susceptible to wear and tear and to provide a stable click operation.

[0054] The click mechanism (CL) pushes the movable part (16) outward in the radial direction to fit into the fitting part (12B), and therefore applies an appropriate amount of elastic force to the movable part (16) to perform the clicking action without applying an axial load to the operating shaft (11) or the guide (15). In addition, since the fitting groove (B1) is formed at a position radially away from the axial center, the fitting groove (B1) can be configured to have a high structural strength that can exert a high resistance force.

[0055] In addition, the plurality of fitting grooves (B1) are arranged in a sawtooth pattern in the rotational direction along the inner circumferential surface of the fitting portion (12B). According to the above configuration, a clicking sensation can be imparted at regular intervals to the rotation of the operating shaft (11).

[0056] Furthermore, the movable parts 16 are provided at multiple locations in the rotational direction of the guide 15. With the above configuration, the mechanisms that cause the movable parts 16 to click are distributed to multiple locations in the rotational direction, making it possible to obtain a clicking sensation of appropriate strength without making the resilience of each part too strong.

[0057] Furthermore, the elastic member (17) is a rubber O-ring (17) that is fitted into a fitting groove (15C) that is formed on the outer periphery of the guide (15) and is recessed annularly around the axis of the operating shaft (11). This configuration allows the elastic member (17) to be simply and appropriately fixed to the guide (15). Furthermore, by using rubber for the elastic member (17), it is possible to reduce the reverberation that occurs when the movable part (16) fits into the fitting groove (B1). This reduces the reverberation of the clicking sound, improving the texture of the clicking sound.

[0058] Furthermore, the movable part 16 is formed of a round bar-shaped pin 16 extending in the axial direction. With this configuration, the movable part 16 can be fitted into the fitting groove B1 so as to make line contact with the fitting groove B1. This improves load distribution compared to a configuration in which these parts make point contact.

[0059] Other Embodiments Although one embodiment of the present invention has been described above, the present invention can be embodied in various forms as described below in addition to the above embodiment.

[0060] 1. The faucet operating device of the present invention can be used in a variety of applications, imparting a clicking sensation to the rotation of the operating shaft. For example, the operating shaft to which the rotating operating member of the faucet operating device is attached may be configured to be fitted with a single lever handle or a switch handle for switching between water flow and water stop.

[0061] The operating shaft can also be installed so that it is embedded in the bathroom wall or the support pillar of the shower unit, and the operating handle can be attached to the front side of the wall or pillar.The faucet operating device can be used not only for bathroom mixer faucets, but also for mixer faucets used in kitchens and bathroom vanities.

[0062] 2. The movable part assembled to the guide so as to be slidable in the radial direction is not limited to a round bar-shaped pin extending in the axial direction. In other words, the movable part may have a shape that fits into and disengages from the multiple fitting grooves with the resilient force of the elastic member as the operating shaft rotates, providing a clicking sensation. For example, it may have a tapered tip that is spherical, hemispherical, or triangular bar-shaped.

[0063] The movable part may be provided at multiple locations in the rotation direction of the guide, or may be provided at only one location. Furthermore, when the movable part is provided at multiple locations in the rotation direction of the guide, the number is not particularly limited, and the number can be any appropriate number, such as two, three, or four locations in the rotation direction.

[0064] 3. The multiple fitting grooves do not necessarily have to be formed in a sawtooth pattern aligned in the rotational direction along the inner circumferential surface of the fitting portion. In other words, some or all of the multiple fitting grooves may be formed at intervals in the rotational direction on the inner circumferential surface of the fitting portion.

[0065] 4. The elastic member may be a spring instead of rubber. When multiple movable parts are attached to the guide, multiple elastic members may be provided so as to apply a resilient force to each movable part individually or collectively.

[0066] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the description of the above embodiments, and is intended to include all modifications within the meaning and scope of the claims.
