Description

  The present invention relates to an operating device for remotely operating a stopper lid provided at a drainage port of a tank body.

  2. Description of the Related Art Conventionally, as an operation device, there is known a device that opens and closes a drain port of a tank body (for example, a bathtub or a washbasin) by vertically moving a predetermined stopper lid by remote operation.

  The operating device includes a rod-shaped operating shaft and a tubular member that is inserted so that the operating shaft can reciprocate. By reciprocating the operating shaft, the driving force due to the displacement of the operating shaft is generated. There has been proposed a device that transmits to a stopper lid side via a predetermined transmission member (see, for example, Patent Document 1).

JP, 2009-57687, A

  By the way, in consideration of the appearance quality, it is preferable that the portion of the tubular member that can be exposed to the outside (the outer surface on the one end side) has a metallic luster. Therefore, it is conceivable that the entire tubular member is made of metal, but in this case, the manufacturing cost may be significantly increased. Therefore, in order to ensure good appearance quality while suppressing the increase in manufacturing cost, the tubular member is formed of resin, and the outer surface on one end side of the tubular member is a cover member made of at least a metal. A method of covering is conceivable. When this method is adopted, the cover member has a hole formed therethrough for inserting the operation shaft.

  However, in the above method, when an operation shaft having at least an outer peripheral surface formed of metal, such as a metal operation shaft, is used, the outer peripheral surface of the operation shaft is made of metal when the operation shaft is reciprocated. The surface of the cover member (particularly the portion forming the hole) may be rubbed (rubbed), and high-pitched noise may occur. If such an abnormal noise occurs, the user may feel a great deal of discomfort. It is also conceivable that the operation shaft and the cover member are rubbed with each other, resulting in wear of the operation shaft and the cover member, which impairs durability and stable operation of the device.

  On the other hand, for example, when an operating shaft having a relatively soft outer peripheral surface such as a resin operating shaft is used, generation of abnormal noise can be suppressed to some extent, but the outer peripheral surface of the operating shaft and the cover member are suppressed. Since the surface of (particularly where the hole is formed) rubs against the surface of the operating shaft, the operating shaft is likely to be significantly worn. As a result, defects in terms of durability and stable operation of the device may be very likely to occur.

  The present invention has been made in view of the above circumstances, and an object thereof is to achieve good appearance quality while suppressing an increase in manufacturing cost, and to secure comfort of a user during use. Another object of the present invention is to provide an operating device which can improve the durability of the device and can achieve more stable operation.

  Hereinafter, each means suitable for solving the above-mentioned object will be described in terms of items. In addition, the action and effect peculiar to the corresponding means will be additionally described as needed.

Means 1. A rod-shaped operating shaft,
A tubular member made of resin, which is inserted such that the operation shaft can reciprocate,
While being provided so as to cover the outer surface of at least one end side of the tubular member, at least the surface is made of a cover member formed by penetrating a hole through which the operation shaft is inserted, and a cover member made of metal,
A driving device configured to transmit a driving force by displacement of the operation shaft to a cap lid side for opening and closing a drainage port of a tank body via a predetermined transmission member,
A guide portion is provided on the inner circumference on one end side of the tubular member, which is close to the outer circumferential surface of the operation shaft and guides the movement of the operation shaft.
The guide portion is configured to be closer to the operation shaft than a portion of the cover member that forms the hole portion ,
A portion of the cover member that forms the hole is configured by a surface that faces the outer peripheral surface of the operation shaft and that forms a thickness direction of the cover member in the cover member.
The operating device is configured such that the operating shaft always penetrates through the hole and projects to the front side of the cover member .

  According to the above means 1, the tubular member is made of resin, and the outer surface of the tubular member made of resin at one end side is at least a cover member made of metal (for example, entirely made of metal. Or those whose surface is covered with metal plating). Therefore, good appearance quality can be realized while suppressing an increase in manufacturing cost.

  On the other hand, when such a cover member is provided, there is a concern that the outer peripheral surface of the operation shaft and the cover member (particularly the portion forming the hole) may be rubbed (rubbed). According to this, the guide portion is configured to be closer to the operation shaft than the portion of the cover member forming the hole. Therefore, rubbing between the outer peripheral surface of the operation shaft and the cover member can be more reliably prevented, and abrasion of the operation shaft and the cover member can be effectively suppressed. As a result, the durability of the device can be improved and more stable operation can be achieved.

  Further, in the case of using an operation shaft having at least an outer peripheral surface formed of metal, such as a metal operation shaft, when the operation shaft is reciprocated, it is possible to more reliably prevent rubbing of the operation shaft with respect to the cover member. Moreover, it is possible to effectively suppress the generation of high-pitched noise. As a result, it is possible to more reliably prevent a situation in which the user feels uncomfortable due to the generation of abnormal noise, and it is possible to ensure the comfort of the user during use.

  In other words, according to the above means 1, when the operating shaft at least the outer peripheral surface of which is made of a relatively soft material is used, a remarkable effect is exhibited particularly in terms of suppressing wear of the operating shaft, When an operating shaft having at least an outer peripheral surface made of metal is used, a remarkable effect is exhibited particularly in terms of suppressing generation of abnormal noise.

  Further, since the movement of the operating shaft is guided by the resin guide portion, the silent operation can be improved. Moreover, since the operation shaft can be smoothly moved, excellent operability can be obtained.

  Means 2. 2. A means 1 according to claim 1, wherein a portion of the cover member that forms the hole is provided in a state of being close to the guide portion along a direction orthogonal to a central axis of the operation shaft. Operating device.

  It should be noted that "a state in which a portion of the cover member forming the hole portion is close to the guide portion along a direction orthogonal to the central axis of the operation shaft" means that the portion orthogonal to the central axis of the operation shaft. It means a state in which the distance from the portion forming the hole in the cover member to the guide portion is extremely small (for example, 0.2 mm or less, more preferably 0.1 mm or less).

  According to the above-mentioned means 2, since the portion forming the hole in the cover member is close to the guide portion, it is more difficult to visually recognize the cylindrical member through the hole. Thereby, a better appearance quality can be realized.

  Means 3. The operating device according to means 1 or 2, wherein the operating shaft is arranged so as to extend in a horizontal direction or an oblique horizontal direction.

  When the operating shaft extends horizontally or diagonally in the horizontal direction, the user must move the operating shaft back and forth or left and right when moving the operating shaft. Compared with the case of moving the operation shaft, the force along the direction intersecting with the extending direction of the operation shaft (particularly the vertical direction) is likely to be unintentionally applied to the operation shaft during operation. Therefore, a situation in which the outer peripheral surface of the operation shaft rubs against the cover member is relatively likely to occur.

  Here, according to the above means 3, since the operation shaft extends in the horizontal direction or the oblique horizontal direction, there is more concern about rubbing between the cover member and the operation shaft. However, by adopting the above means 1 or the like, Even when the operation shaft extends in the horizontal direction or the oblique horizontal direction, it is possible to more reliably prevent the operation shaft from rubbing against the cover member. In other words, the above-mentioned means 1 and the like are particularly effective when the operation shaft extends in the horizontal direction or the oblique horizontal direction.

It is sectional drawing of an operating device etc. in the state which moved the operating member forward. It is sectional drawing of an operating device etc. in the state which made the operating member return. It is a partial expanded sectional view for explaining the physical relationship of a guide part, a hole, etc.

The vanity stand 100 is provided with a back guard 101 as an attachment object on the side opposite to the side on which the user is located with a wash basin (not shown) in between. The back guard 101 has a plate shape extending in the vertical direction, and the back guard 101 is provided with a mounting hole 102 penetrating in the plate thickness direction, that is, the horizontal direction.

  The operating device 1 includes a tubular member 2, a cover member 3, a nut member 4, an operating member 5, a transmitting member 6, and a closing member 7.

  The tubular member 2 is formed of a predetermined resin (for example, POM or the like), and has a tubular shape with a through hole having a circular cross section at the center. The operation member 5 is inserted into the inner circumference of the tubular member 2. Further, the tubular member 2 includes a cylindrical main body portion 21 and a flange portion 22 protruding outward from one end portion of the main body portion 21. Further, a male screw portion 21A is formed on the outer periphery of the main body portion 21.

  The cover member 3 has a thin plate shape and is made of a metal such as SUS. The cover member 3 includes an outer surface on one end side of the tubular member 2 (specifically, from a portion located immediately outside the opening on the one end side of the tubular member 2 to a portion beyond the outermost peripheral portion of the collar portion 22). The outer surface is bent back and is fixed to the collar portion 22. The shapes of the portions of the tubular member 2 and the cover member 3 located particularly on the operation member 5 side will be described in detail later.

  The nut member 4 is used to fix the tubular member 2 to the back guard 101. The nut member 4 is formed in an annular shape and has a first female screw portion 4A capable of screwing the male screw portion 21A on its inner circumference. Then, after inserting the tubular member 2 into the mounting hole 102, one end side of the male screw portion 21A is screwed into the first female screw portion 4A, and the back guard 101 is sandwiched by the collar portion 22 and the nut member 4. The tubular member 2 is attached to the back guard 101. An annular seal member 8 made of an elastically deformable material is disposed between the collar portion 22 and the back guard 101 while being sandwiched between them. The seal member 8 prevents water from entering the back side of the back guard 101 passing between the collar portion 22 and the back guard 101.

  The operating member 5 is operated when opening and closing a drainage port (not shown) formed in the washbasin. In the present embodiment, the operating member 5 is disposed slightly above the washbasin and is positioned diagonally below and to the front when viewed from the user (for example, a standing adult). .. The operating member 5 is inserted into the inner periphery of the tubular member 2 and is rod-shaped operating shaft 51 that is reciprocally movable along the inner periphery of the tubular member 2, and is screwed to one end of the operating shaft 51. And a control knob portion 52 for operation.

  The operation shaft 51 is formed of a predetermined metal in a rod shape (a cylindrical shape in the present embodiment), and is provided so as to extend in the horizontal direction. Further, the operation shaft 51 is provided at its other end with a recess 51A for connecting the transmission member 6. Then, as shown in FIGS. 1 and 2, by pushing and pulling the knob portion 52, the operating shaft 51 and the transmission member 6 connected thereto are reciprocally moved (note that FIG. 2 shows a state in which the user pushes the operation member 5 to move the operation shaft 51 and the like forward, and FIG. 2 shows a state in which the user pulls the operation member 5 to move the operation shaft 51 and the like backward. Shows the state of).

  Further, an annular seal member 9 made of an elastically deformable material is provided between the outer peripheral surface of the operation shaft 51 and the inner peripheral surface of the tubular member 2 in a state of being sandwiched between both surfaces. The seal member 9 prevents the water that has entered between the operation shaft 51 and the tubular member 2 from leaking to the transmission member 6 side.

  The transmission member 6 is made of, for example, a wire, and transmits the driving force generated by the displacement of the operation shaft 51 to the plug lid (not shown) provided corresponding to the drainage port. The transmission member 6 is arranged on the inner circumference of the tubular tube member 10, and reciprocates with respect to the tube member 10 as the operation shaft 51 is displaced. Then, as the transmission member 6 reciprocates, the plug lid moves up and down to open and close the drainage port. A flare portion 11 formed by flare processing or the like and protruding outward in the radial direction is provided at the end of the tube member 10.

  Further, the end portion of the transmission member 6 is exposed from the end portion of the tube member 10, and a spherical terminal connecting portion 12 protruding from the outer circumference is fitted to the outer circumference of the end portion. The operation member 5 (operation shaft 51) and the transmission member 6 are connected by arranging the terminal connection portion 12 in the recess 51A.

  The closing member 7 is attached to the other end of the tubular member 2 and has a function of holding the end of the tube member 10 and preventing the operation member 5 from coming off from the other end of the tubular member 2. .. The closing member 7 includes a tubular portion 71 and a lid portion 72 that projects inward from the inner circumference of the end portion of the tubular portion 71.

  The cylindrical portion 71 has a cylindrical shape, and is provided with a second female threaded portion 71A on the inner circumference thereof, into which the male threaded portion 21A can be screwed. Then, the closing member 7 is attached to the tubular member 2 by screwing the male screw portion 21A into the second female screw portion 71A.

  The lid portion 72 is arranged corresponding to the opening on the other end side of the tubular member 2 in a state where the closing member 7 is attached to the tubular member 2, and the transmission member 6 and the transmission member 6 are provided at the center thereof. A through hole is formed for the tube member 10 to pass through. Further, the lid portion 72 sandwiches the flare portion 11 with the other end portion of the tubular member 2 in a state where the closing member 7 is attached to the tubular member 2. As a result, the end of the tube member 10 is held by the tubular member 2 and the closing member 7.

  Next, the shapes of the portions of the tubular member 2 and the cover member 3 located on the operation member 5 side will be described.

  As shown in FIG. 3, the cover member 3 has a circular hole portion 31 formed at the center thereof so as to penetrate therethrough. The hole portion 31 is a portion through which the operation shaft 51 is inserted, and is provided concentrically with the guide portion 23 described below when viewed from the distal end portion (knob portion 52) side of the operation member 5.

  The tubular member 2 includes a guide portion 23 that extends along the axial direction of the tubular member 2 on the inner circumference of the one end side. The guide portion 23 has an inner diameter substantially equal to the outer diameter of the operation shaft 51, and is in a state of being close to the outer peripheral surface of the operation shaft 51. The guide portion 23 guides the reciprocating movement of the operation member 5 (operation shaft 51).

  The guide portion 23 is provided closer to the outer peripheral surface of the operation shaft 51 than the portion of the cover member 3 where the hole portion 31 is formed. However, the portion of the cover member 3 where the hole 31 is formed is not excessively separated from the outer peripheral surface of the operation shaft 51, but is sufficiently close to the outer peripheral surface of the operation shaft 51. There is. As a result, along the direction orthogonal to the central axis of the operation shaft 51, the portion of the cover member 3 that forms the hole 31 is in a state of being close to the guide portion 23. In the present embodiment, the distance L from the portion forming the hole 31 in the cover member 3 to the guide portion 23 along the direction orthogonal to the central axis of the operation shaft 51 is sufficiently small (for example, 0. 2 mm or less, and more preferably 0.1 mm or less).

  The hole 31 can be formed by punching the cover member 3 using a predetermined jig (for example, punching punch). Here, the punching is preferably performed from the front surface side of the cover member 3 (the surface side which is located on the side opposite to the side arranged on the tubular member 2 side and is visible from the outside). In this case, even if burrs or the like are formed due to the punching process, the burrs or the like are formed on the back surface side (the cylindrical member 2 side) of the cover member 3 and on the front surface side of the cover member 3. Will be hardly formed. Therefore, it is possible to obtain good appearance quality without performing a special process for removing burrs and the like.

  As described above in detail, according to the present embodiment, the tubular member 2 is made of resin, and the outer surface on the one end side of the tubular member 2 made of resin is covered with the cover member 3 made of metal. ing. Therefore, good appearance quality can be realized while suppressing an increase in manufacturing cost.

  On the other hand, when such a cover member 3 is provided, there is a concern that the outer peripheral surface of the operation shaft 51 and the cover member 3 (particularly the portion forming the hole 31) may be rubbed (rubbed). In particular, in the present embodiment, the operation shaft 51 extends in the horizontal direction, and when the operation member 5 is operated, a force along a direction (particularly a vertical direction) intersecting the direction in which the operation shaft 51 extends is intended for the operation shaft 51. Since it is easy to add without doing so, there is a particular concern that the outer peripheral surface of the operating shaft 51 and the cover member 3 rub.

  In this respect, according to the present embodiment, the guide portion 23 is closer to the outer peripheral surface of the operation shaft 51 than the portion of the cover member 3 where the hole portion 31 is formed. Therefore, even if the operation shaft 51 extends in the horizontal direction and the operation shaft 51 and the cover member 3 are particularly likely to be rubbed, the occurrence of such rub can be more reliably prevented. As a result, it is possible to effectively suppress wear of the operation shaft 51 and the cover member 3, and it is possible to improve the durability of the device and achieve more stable operation.

  Further, in the case of using the operation shaft 51 made of metal, such as the case of using the operation shaft 51 made of metal as in the present embodiment, when the operation shaft 51 is reciprocally moved, It is feared that the outer peripheral surface of the metallic operation shaft 51 rubs against the surface of the metallic cover member 3 to generate a high-pitched noise, but as described above, the operation shaft 51 and the cover member 3 are Since the rubbing can be more surely prevented, it is possible to effectively suppress the generation of such abnormal noise. As a result, it is possible to more reliably prevent a situation in which the user feels uncomfortable due to the generation of abnormal noise, and it is possible to ensure the comfort of the user during use.

  Further, since the movement of the operation shaft 51 is guided by the resin guide portion 23, the quietness during the operation can be improved. Further, since the operation shaft 51 can be moved smoothly, excellent operability can be obtained.

  In addition, since the distance L is sufficiently small and the portion of the cover member 3 that forms the hole 31 is close to the guide portion 23, it is possible to visually recognize the tubular member 2 through the hole 31. It can be more difficult. Thereby, a better appearance quality can be realized.

  It should be noted that the present invention is not limited to the contents described in the above embodiment, and may be implemented as follows, for example. Of course, other application examples and modification examples not illustrated below are naturally possible.

  (A) In the above embodiment, the operation shaft 51 is made of metal, but the operation shaft may be configured such that only the outer peripheral surface is made of metal by applying metal plating to the surface. Also in this case, it is possible to more reliably prevent generation of abnormal noise due to rubbing of the outer peripheral surface of the operation shaft and the cover member 3.

  Further, an operation shaft formed of resin, rubber, or the like, that is, at least an outer peripheral surface of the operation shaft formed of a relatively soft material may be used. In this case, wear of the operating shaft due to rubbing with the cover member 3 is particularly concerned, but such wear is likely to occur by configuring the tubular member 2 and the cover member 3 as in the above embodiment. Even with the operating shaft, its wear can be suppressed very effectively.

  (B) In the above embodiment, the cover member 3 is made of metal, but the cover member may be configured such that at least only the surface is made of metal by applying metal plating to the surface.

  (C) In the above embodiment, the operating shaft 51 is configured to extend in the horizontal direction, but the operating shaft 51 may be configured to extend in the diagonal horizontal direction. Even in this case, when the operating member 5 is operated, a force along a direction intersecting with the extending direction of the operating shaft 51 (particularly, a vertical direction) is likely to be unintentionally applied to the operating shaft 51. Rubbing between the outer peripheral surface of the shaft 51 and the cover member 3 is likely to occur, but by configuring the tubular member 2 and the cover member 3 as in the above-described embodiment, the rubbing of the operation shaft 51 and the cover member 3 can be more reliably performed. Can be prevented.

  Further, the operation shaft may be configured to extend in the vertical direction.

  (D) In the above-described embodiment, the operating device 1 uses the back guard 101 as an object to be attached, but the object to be attached is not limited to this. For example, a bath such as a washbasin, a bathtub, or a sink may be used as the attachment target. Further, a structure provided near the tank body (for example, a counter provided near the washbasin, a counter of a sink, or the like) may be an object to be attached.
