Description

  The present invention relates to an operating device for remotely operating a plug lid provided at a drain outlet of a tank body.

  Conventionally, as an operation device, a device that opens and closes a drainage port of a tank body (for example, a bathtub, a basin, or the like) by moving a predetermined stopper lid up and down by remote control is known.

  Further, the operating device includes a rod-shaped operating shaft and a cylindrical member inserted in a state where the operating shaft can reciprocate, and by reciprocating the operating shaft, driving force due to displacement of the operating shaft can be obtained. There has been proposed one 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 view of the appearance quality, it is preferable that the surface of the cylindrical member that can be exposed to the outside (the outer surface on one end side) has a metallic luster. Therefore, it is conceivable to form the entire cylindrical member from metal, but in this case, the manufacturing cost may be significantly increased. Therefore, while suppressing the increase in manufacturing cost, in order to ensure good appearance quality, the cylindrical member is formed of resin, and the outer surface on one end side of the cylindrical member is at least a cover member made of metal. A method of covering is conceivable. When this method is employed, a hole for inserting the operation shaft is formed through the cover member.

  However, in the above method, when an operation shaft having 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. And the surface of the cover member (particularly the part forming the hole) are rubbed (rubbed), and there is a risk that high-pitched abnormal noise will be generated. If such an abnormal noise is generated, there is a possibility that the user may have a considerable discomfort. In addition, it is conceivable that the operation shaft and the cover member are rubbed to cause wear on the operation shaft and the cover member, thereby impairing durability and stable operation of the apparatus.

  On the other hand, for example, when an operation shaft having a relatively soft outer peripheral surface such as a resin operation shaft is used, the generation of abnormal noise can be suppressed to some extent, but the outer peripheral surface of the operation shaft and the cover member By rubbing with the surface of (particularly, the part where the hole is formed), the wear of the operating shaft is significantly facilitated. As a result, there is a risk that problems in terms of durability and stable operation of the apparatus are very likely to occur.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a good appearance quality while suppressing an increase in manufacturing cost and to ensure a user's comfort during use. It is another object of the present invention to provide an operating device that can improve the durability of the device and achieve more stable operation.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A rod-shaped operating shaft;
A cylindrical member made of resin inserted in a state where the operation shaft can reciprocate;
The cylindrical member is provided so as to cover an outer surface on at least one end side, and a hole portion through which the operation shaft is inserted is formed, and at least a surface is provided with a metal cover member,
An operating device configured to transmit a driving force due to displacement of the operating shaft to a plug lid side for opening and closing a drainage port of the tank body through a predetermined transmission member,
A guide portion is provided on the inner periphery of the one end side of the cylindrical member so as to be close to the outer peripheral surface of the operation shaft and guide the movement of the operation shaft.
The operation device, wherein the guide portion is configured to be closer to the operation shaft than a portion of the cover member that forms the hole portion.

  According to the above means 1, the cylindrical member is made of resin, and at least one outer side surface of the resin cylindrical member is formed of a cover member (for example, the whole is made of metal). Or the surface of which is covered with metal plating). Therefore, it is possible to realize a good appearance quality while suppressing an increase in manufacturing cost.

  On the other hand, in the case where 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 configuration, the guide portion is configured to be closer to the operation shaft than the portion where the hole portion is formed in the cover member. Therefore, rubbing between the outer peripheral surface of the operation shaft and the cover member can be more reliably prevented, and the occurrence of wear on the operation shaft and the cover member can be effectively suppressed. As a result, the durability of the apparatus can be improved and more stable operation can be achieved.

  In addition, when using an operation shaft having at least an outer peripheral surface formed of metal, such as a metal operation shaft, it is possible to more reliably prevent the operation shaft from rubbing against the cover member. In addition, it is possible to effectively suppress the occurrence of high-pitched abnormal noise. As a result, it is possible to more reliably prevent the user from feeling uncomfortable with the occurrence of abnormal noise, and to ensure the user's comfort during use.

  That is, according to the above means 1, when an operation shaft formed of a material that is relatively soft at least on the outer peripheral surface is used, a remarkable effect is exhibited particularly in terms of suppressing wear of the operation shaft. In the case where a metal operating shaft is used at least on the outer peripheral surface, a remarkable effect is exhibited particularly in terms of suppressing the generation of abnormal noise.

  Furthermore, since the movement of the operation shaft is guided by the resin guide portion, it is possible to improve the quietness during operation. Further, since the operation shaft can be moved smoothly, excellent operability can be obtained.

  Mean 2. The means for forming the hole portion in the cover member is provided in a state of being close to the guide portion along a direction orthogonal to the central axis of the operation shaft. Operating device.

  In addition, “the state in which the hole forming portion of the cover member is close to the guide portion along the direction orthogonal to the central axis of the operation shaft” is in the direction orthogonal to the central axis of the operation shaft. This means that the distance from the portion where the hole portion in the cover member is formed to the guide portion is very small (for example, 0.2 mm or less, more preferably 0.1 mm or less).

  According to the above means 2, since the part of the cover member that forms the hole is close to the guide part, it is more difficult to visually recognize the tubular member through the hole. Thereby, better appearance quality can be realized.

  Means 3. 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 operation axis extends in the horizontal direction or the oblique horizontal direction, the user moves the operation axis back and forth or right and left when moving the operation axis. In this case, the operation axis is moved up and down. In comparison with the case of moving the control shaft to the control shaft, a situation in which a force along the direction (particularly the vertical direction) intersecting the direction in which the control shaft extends is unintentionally applied to the control shaft during the 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 means 3, since the operation shaft extends in the horizontal direction or the oblique horizontal direction, there is a greater concern about the friction between the cover member and the operation shaft, but by adopting the means 1 or the like, Even when the operation shaft extends in the horizontal direction or the oblique horizontal direction, the operation shaft can be more reliably prevented from rubbing against the cover member. In other words, the 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 the operating device etc. in the state which moved the operating member forward. It is sectional drawing of the operating device etc. in the state which moved the operating member backward. It is a partial expanded sectional view for demonstrating positional relationships, such as a guide part and a hole part.

The operation member 5 is inserted through the inner periphery of the cylindrical member 2. The tubular member 2 includes a cylindrical main body 21 and a flange 22 that protrudes outward from one end of the main body 21. Furthermore, a male screw portion 21 </ b> A is formed on the outer periphery of the main body portion 21.

  The cover member 3 has a thin plate shape, and is formed of a metal such as SUS, for example. The cover member 3 has an outer surface on one end side of the tubular member 2 (specifically, from a portion located just outside the one end side opening of the tubular member 2 to a portion beyond the outermost peripheral portion of the flange portion 22. Surface) and the outer portion is bent back so as to be fixed to the collar portion 22. In addition, the shape of the part especially located in the operation member 5 side in the cylindrical member 2 and the cover member 3 is explained in full detail later.

  The nut member 4 is used for fixing the tubular member 2 to the back guard 101. The nut member 4 has an annular shape, and has a first female screw portion 4A on the inner periphery that can be screwed into the male screw portion 21A. Then, after inserting the cylindrical member 2 into the mounting hole 102, one end side of the male screw portion 21 </ b> A is screwed into the first female screw portion 4 </ b> A, and the back guard 101 is sandwiched between the flange 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 the two. The sealing member 8 prevents water from entering the back side of the back guard 101 that passes between the flange portion 22 and the back guard 101.

  The operation member 5 is operated when opening and closing a drain port (not shown) formed in the basin. In the present embodiment, the operation member 5 is disposed slightly above the wash basin, and is positioned obliquely forward and downward as viewed from the user (for example, a general adult standing up). . The operation member 5 is inserted into the inner periphery of the cylindrical member 2 and is reciprocally movable along the inner periphery of the cylindrical member 2. And an operation knob 52 for operation.

  The operation shaft 51 is formed in a rod shape (in this embodiment, a column shape) from a predetermined metal, and is provided to extend in the horizontal direction. In addition, the operation shaft 51 includes a recess 51 </ b> A for connecting the transmission member 6 at the other end. As shown in FIGS. 1 and 2, by pushing and pulling the knob portion 52, the transmission member 6 connected to the operating shaft 51 is reciprocated (see FIG. 1). FIG. 2 shows a state when the operation shaft 51 is moved forward by the user pushing the operation member 5, and FIG. 2 shows a state where the user moves the operation shaft 51, etc. backward by pulling the operation member 5. Status).

  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 cylindrical member 2 in a state of being sandwiched between both surfaces. The seal member 9 prevents leakage of water that has entered between the operation shaft 51 and the cylindrical member 2 to the transmission member 6 side.

  The transmission member 6 is composed of, for example, a wire or the like, and transmits a driving force due to the displacement of the operation shaft 51 to a plug lid (not shown) provided corresponding to the drain port. The transmission member 6 is disposed on the inner periphery of the tubular tube member 10 and reciprocates with respect to the tube member 10 as the operation shaft 51 is displaced. Then, the drain cover is opened and closed by moving the stopper lid up and down as the transmission member 6 reciprocates. In addition, the flare part 11 which protrudes to the radial direction outer side formed by the flare process etc. is provided in the edge part of the tube member 10. FIG.

  Further, the end portion of the transmission member 6 is exposed from the end portion of the tube member 10, and a spherical terminal connection portion 12 protruding from the outer periphery is fitted into the outer periphery of the end portion. And the operation member 5 (operation shaft 51) and the transmission member 6 are connected by arrange | positioning the terminal connection part 12 in the said recessed part 51A.

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

  The cylindrical portion 71 has a cylindrical shape and includes a second female screw portion 71A capable of screwing the male screw portion 21A on its inner periphery. Then, the closing member 7 is attached to the cylindrical member 2 by the male screw portion 21A being screwed into the second female screw portion 71A.

  The lid portion 72 is disposed 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. A through hole through which the tube member 10 passes is formed. The lid 72 is configured to sandwich the flare portion 11 between the lid member 72 and the other end portion of the tubular member 2 in a state where the closing member 7 is attached to the tubular member 2. Thereby, the end portion of the tube member 10 is held by the cylindrical member 2 and the closing member 7.

  Next, the shape of the part located on the operation member 5 side in the cylindrical member 2 and the cover member 3 will be described.

  As shown in FIG. 3, the cover member 3 includes a circular hole portion 31 formed through the center thereof. 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 cylindrical member 2 includes a guide portion 23 extending along its own axial direction on the inner periphery on 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 member 23 guides the reciprocating movement of the operation member 5 (operation shaft 51).

  The guide portion 23 is provided in a state closer to the outer peripheral surface of the operation shaft 51 than a portion where the hole portion 31 is formed in the cover member 3. 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 and is sufficiently close to the outer peripheral surface of the operation shaft 51. Yes. Thereby, the site | part which forms the hole part 31 in the cover member 3 is the state which adjoined with respect to the guide part 23 along the direction orthogonal to the central axis of the operating shaft 51. FIG. In the present embodiment, the distance L from the portion of the cover member 3 where the hole 31 is formed to the guide 23 along the direction orthogonal to the central axis of the operation shaft 51 is sufficiently small (for example, 0. 2 mm or less, 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, a punch). Here, it is preferable to perform the punching from the surface side of the cover member 3 (the surface side that is located on the opposite side to the side disposed on the cylindrical member 2 side and is visible from the outside). In this case, even if burrs or the like are formed by the punching process, the burrs or the like are formed on the back surface side (tubular member 2 side) of the cover member 3, and are formed on the front surface side of the cover member 3. Is hardly formed. Therefore, it is possible to obtain a 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 cylindrical member 2 is formed of resin, and the outer surface on one end side of the resin cylindrical member 2 is covered with the metal cover member 3. ing. Therefore, it is possible to realize a good appearance quality 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 where the hole 31 is formed) are 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 the direction (particularly the vertical direction) intersecting the direction in which the operation shaft 51 extends is intended for the operation shaft 51. Therefore, there is a particular concern that the outer peripheral surface of the operation shaft 51 and the cover member 3 are rubbed.

  In this regard, according to the present embodiment, the guide portion 23 is in a state of being closer to the outer peripheral surface of the operation shaft 51 than a portion where the hole portion 31 is formed in the cover member 3. Therefore, even when the operation shaft 51 extends in the horizontal direction and the friction between the operation shaft 51 and the cover member 3 is particularly concerned, the occurrence of such friction can be prevented more reliably. As a result, it is possible to effectively suppress the operation shaft 51 and the cover member 3 from being worn, and to improve the durability of the apparatus and to achieve a more stable operation.

  Further, in the case of using an operation shaft having at least an outer peripheral surface formed of metal, such as when using a metal operation shaft 51 as in the present embodiment, when the operation shaft 51 is reciprocated, Although there is a concern that the outer surface of the metal operation shaft 51 rubs against the surface of the metal cover member 3, a high-pitched abnormal noise may occur, but as described above, the operation shaft 51 and the cover member 3 Since the rubbing can be prevented more reliably, the generation of such abnormal noise can be effectively suppressed. As a result, it is possible to more reliably prevent the user from feeling uncomfortable with the occurrence of abnormal noise, and to ensure the user's comfort during use.

  Furthermore, since the movement of the operation shaft 51 is guided by the resin guide portion 23, it is possible to improve the quietness during operation. 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, the tubular member 2 can be viewed through the hole 31. It can be more difficult. Thereby, better appearance quality can be realized.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the operation shaft 51 is made of metal. However, for example, the operation shaft may be configured such that only the outer peripheral surface is made of metal by performing metal plating on the surface. Even in this case, it is possible to more reliably prevent the 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, an operation shaft formed of a material whose outer peripheral surface is relatively soft may be used. In this case, there is a particular concern about wear of the operating shaft due to rubbing with the cover member 3, but such wear is likely to occur by configuring the cylindrical member 2 and the cover member 3 as in the above embodiment. Even the operating shaft can very effectively suppress the wear.

  (B) In the above embodiment, the cover member 3 is made of metal. However, for example, the cover member may be configured so that at least only the surface is made of metal by performing metal plating on the surface.

  (C) In the above embodiment, the operation shaft 51 is configured to extend in the horizontal direction. However, the operation shaft 51 may be configured to extend in an oblique horizontal direction. Even in this case, when the operation member 5 is operated, a force along the direction (particularly the vertical direction) intersecting the extending direction of the operation shaft 51 is easily applied to the operation shaft 51 unintentionally. Although rubbing between the outer peripheral surface of the shaft 51 and the cover member 3 is likely to occur, the rubbing between the operation shaft 51 and the cover member 3 can be ensured by configuring the cylindrical member 2 and the cover member 3 as in the above embodiment. Can be prevented.

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

  (D) In the said embodiment, although the operating device 1 makes the back guard 101 the attachment target object, an attachment target object is not restricted to this. For example, it is good also considering tank bodies, such as a washbasin, a bathtub, and a sink, as an attachment target object. Further, a structure provided in the vicinity of the tank body (for example, a counter provided near the wash basin or a counter of a sink) may be used as the attachment target.
