Description

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

  2. Description of the Related Art Conventionally, a push button type is known as an operation device for remotely operating a plug lid and opening and closing a drain outlet. Such an operating device is disposed inside a guide member, a cylindrical guide member that is attached to a predetermined tank body (for example, a bathtub, a washbasin, etc.) or an object to be attached that is a structure in the vicinity thereof, And an operation button capable of reciprocating along the axial direction of the guide member. When the operation button moves, the outer surface of the operation button moves along the inner surface of the guide member.

  Furthermore, in order to improve the appearance quality, a method is proposed in which the operation button is composed of a resin main body part and a metal cover part that covers a part of the main body part located on the surface side of the attachment object. Has been. As a method for fixing (integrating) the main body portion to the cover portion, there is a method for fixing (integrating) both by insert molding, but this method is costly in terms of manufacturing ease and manufacturing equipment. Inferior to productivity.

  Therefore, in order to improve productivity, a method of caulking and fixing the cover portion to the main body portion can be considered. In this method, a stepped portion where the cover portion is caulked is formed on the outer periphery of the main body portion. The stepped portion has a large diameter at one end side (surface side of the mounting object) of the main body portion and a small diameter at the other end side outer periphery of the main body portion, that is, a diameter difference is provided on the outer periphery of the main body portion. (See, for example, Patent Document 1). The cover part is fixed so as to cover the large diameter part of the main body part. Further, in order to ensure the ease of caulking and fixing, a portion of the main body portion located on the other end side from the step portion is configured not to protrude outward from the step portion. Therefore, in the operation button, the outer surface of the cover portion is positioned on the outermost side, and when the operation button is moved, the outer surface of the cover portion moves along the inner surface of the guide member.

JP2013-253422A

  By the way, for example, when the entire guide member is made of metal, at least a part of the inner surface of the guide member corresponding to the movement range of the cover portion may be made of metal. In this case, with the operation button having the outer surface of the cover portion positioned on the outermost side as described above, the outer surface of the cover portion and the inner surface (metal portion) of the guide member are rubbed with each other when the operation button is moved. There is a risk of generating unusual noise.

  The present invention has been made in view of the above circumstances, and an object thereof is an operation that can more reliably prevent the generation of abnormal noise when the operation button is moved while improving the appearance quality and productivity. To provide an apparatus.

  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 cylindrical guide member inserted into a through-hole of a predetermined attachment object;
An operation button that is arranged on the inner side of the guide member in a state where one end side is located on the surface side of the attachment object, and is configured to be movable along the inner surface of the guide member;
A transmission member for transmitting the displacement of the operation button to the stopper lid provided at the drain of the tank body;
The operation buttons are
A resin body,
A metal cover fixed to one end of the main body,
Of the inner surface of the guide member, an operating device in which at least a part of the portion corresponding to the movement range of the cover portion is made of metal,
The main body is
A head located on one end of itself,
A plurality of indentations that are located on the other end side of the head and spaced apart along the circumferential direction;
A sliding part located on the other end side of the head and at least a part of itself between the adjacent concave parts,
The cover part is
An exposed portion that covers one end surface of the head and is exposed on the surface side of the attachment object;
A cylindrical portion that extends from the outer edge of the exposed portion toward the other end, and covers the side of the head;
A plurality of legs provided at the other end of the cylindrical part and spaced apart along the circumferential direction;
The cover part is swaged and fixed to the main body part by caulking the leg part to the part forming the concave portion of the main body part,
The sliding part is located outside the outer side surfaces of the cylindrical part and the leg part,
An operation device configured to move the sliding portion along an inner surface of the guide member when the operation button moves.

  According to the means 1, since the cover portion is provided on the operation button, it is possible to improve the appearance quality. Moreover, since it is the structure which crimps and fixes a cover part to a main-body part, productivity can be improved.

  On the other hand, in the above means 1, since at least a part of the inner surface of the guide member corresponding to the movement range of the cover portion is made of metal, there is a concern about the generation of abnormal noise when the operation button is moved. The In this respect, according to the means 1, the sliding portion provided in the resin main body is located outside the outer surface of the cylindrical portion and the leg portion, and the sliding is performed when the operation button is moved. The part moves along the inner surface of the guide member. Therefore, when the operation button is moved, when the operation button comes into contact with the guide member, the resin portion (sliding portion) rubs against the inner surface of the guide member, so that the generation of abnormal noise can be prevented more reliably. .

  Further, according to the above means 1, the plurality of leg portions provided at intervals along the circumferential direction are crimped on the portion of the main body portion where the concave portion is formed, whereby the cover portion is provided on the main body portion. Fixed. Therefore, the load applied to the cover part and the main body part during caulking can be reduced as compared with the case where the entire outer edge of the cover part is caulked and fixed to the main body part. As a result, it is possible to more reliably prevent the cover portion and the main body portion from being damaged during caulking.

  According to the above means 1, as a result, a gap can be formed between the outer surface of the operation button and the inner surface of the guide member on one end side of the operation button (the surface side of the attachment object). At this time, if the main body portion (resin portion) of the operation button is easily visible through the gap, the effect of improving the appearance quality by providing the cover portion may not be sufficiently achieved.

  In this regard, in the above-described means 1, a cylindrical portion is provided in the cover portion, and the gap is formed between the outer surface of the cylindrical portion and the inner surface of the guide member. And a main-body part (resin part) will be exposed to the outer surface of an operation button in the other end side (back | inner side) rather than the said clearance gap (tubular part). Therefore, it becomes difficult to visually recognize the main body (resin portion) through the gap, and the effect of improving the appearance quality by providing the cover can be sufficiently exhibited.

Mean 2. The main body has a cylindrical shape,
2. The operating device according to claim 1, wherein the main body includes an inner protrusion that is provided corresponding to a position where the recess is formed along the circumferential direction and protrudes inward.

  According to the means 2, when the cover part (leg part) is caulked and fixed to the main body part (recessed part forming part), the inner protrusion provided corresponding to the position where the recessed part is formed is used. Thus, the recess and the leg can be accurately aligned. Therefore, a caulking process can be performed more easily and productivity can be improved.

Means 3. The main body includes a stepped shoulder located between the head and the sliding portion,
3. The operating device according to claim 1, wherein a portion of the shoulder portion located outside the cover portion is configured to incline toward the other end side from the inside toward the outside. .

  As described above, a gap may be formed between the outer surface of the operation button and the inner surface of the guide member on one end side of the operation button (the surface side of the attachment object). And if a clearance gap is formed, it will be thought that water permeates into the inside of a guide member through the clearance gap. Here, in order to configure the sliding portion to be located outside the outer surface of the cylindrical portion or the like, when a stepped shoulder portion is provided between the head portion and the sliding portion in the main body portion, Water that has passed through the gap tends to accumulate on the shoulder. If water easily collects in the shoulder, dirt or the like may easily adhere to the operation button (shoulder).

  In this respect, according to the means 3, the portion of the shoulder portion located outside the cover portion is inclined toward the other end side from the inner side toward the outer side, so that it is difficult for water to collect in the shoulder portion. Therefore, adhesion of dirt or the like to the operation button can be effectively suppressed, and hygiene can be improved. In addition, since dirt or the like is less likely to adhere to the operation buttons, it is not necessary to frequently perform maintenance (cleaning or the like) for ensuring hygiene, and the maintenance frequency can be reduced.

Means 4. The main body includes a stepped shoulder located between the head and the sliding portion,
The operating device according to any one of means 1 to 3, wherein the recess has a groove shape reaching the other end of the main body.

  According to the above means 4, even if water enters the gap between the outer surface of the operation button and the inner surface of the guide member on one end side of the operation button, the water that has entered through the groove-shaped recess Is easier to flow out of the operation buttons. Therefore, it is possible to more reliably prevent water from accumulating in the shoulder portion, and further improve hygiene. In addition, since the adhesion of dirt and the like is further suppressed, the maintenance frequency can be further reduced.

  Furthermore, if the concave portion has a shape extending along the central axis of the main body portion, a crimping tool (such as a punch) for pressing the leg portion is used to press the leg portion against the main body portion. The other end of the main body can be moved in the direction of the central axis of the main body through the recess. Accordingly, it is sufficient that the tool is movable in the direction of the central axis of the main body, so that the manufacturing cost can be reduced, and further productivity can be improved.

Means 5. Of the inner surface of the guide member, at least a portion corresponding to the movement range of the recess is cylindrical.
The recess extends along the axial direction of the main body, forms a groove that reaches the other end of the main body, and
The virtual surface including the sliding portion has a cylindrical shape,

  The recess extends along the axial direction of the main body, has a groove shape reaching the other end of the main body, and the inner surface of the guide member (particularly, the portion corresponding to the recess) is cylindrical, and the sliding portion In some cases, a virtual surface including a cylindrical shape is formed. In this case, in the main body portion, when the two concave portions are provided so as to sandwich the central axis of the main body portion, the amount of play of the operation button with respect to the guide member at the position sandwiched between the two concave portions is the above-described position at the position not sandwiched between the two concave portions. The amount is slightly larger than the backlash. Therefore, the operability when moving the operation button may be reduced.

  In this regard, according to the means 5, the sliding portion is provided at a position of the main body portion that sandwiches the central axis of the main body portion with the recess. In other words, the two concave portions are configured not to be disposed across the central axis of the main body portion. Therefore, the amount of play of the operation button with respect to the guide member can be reduced, and the operability can be improved.

  Means 6. The operation according to any one of means 1 to 3, wherein the sliding portion is configured to be continuous along the circumferential direction of the main body portion at least in a part of the main body portion in the axial direction. apparatus.

  According to the means 6, the sliding portion is configured so as to be continuous along the circumferential direction, that is, without being interrupted along the circumferential direction, at least partially along the axial direction of the main body portion. . Therefore, the amount of play of the operation button with respect to the guide member can be further reduced, and the operability can be further improved.

Further, the large-diameter portion 211B is formed with a protruding portion 211D that protrudes radially inward.

  The support part 212 is connected to the outer periphery of one end of the holding part 213 and supports the holding part 213. Further, a plurality of drain holes 212A extending in the vertical direction are formed in the support portion 212, and the water that has entered the guide member 2 flows down into the joint member 3 through the drain holes 212A. .

  The holding part 213 has a cylindrical shape and is arranged coaxially with the cylindrical part 211. Further, a locking portion 213A that protrudes radially inward is formed on the inner periphery of the holding portion 213, and the locking portion 213A is deformed in the radial direction when the holding portion 213 is bent and deformed in the radial direction. It is possible to elastically deform (move) along.

  The flange portion 22 includes a sliding portion 221 having a cylindrical shape, and a flange portion 222 that protrudes radially outward from one end (upper end) of the sliding portion 221.

  The sliding portion 221 is inserted through the inner periphery of the large diameter portion 211B and has an inner diameter substantially the same as that of the small diameter portion 211C. Thereby, in the inner peripheral surface of the guide member 2, in the direction of the central axis CL <b> 1, the inner surface of the part corresponding to the moving range of the sliding part 612 </ b> B and the concave part 612 </ b> A (described later from the sliding part 221 to the small diameter part 211). The inner peripheral surface) has a smooth cylindrical shape with a substantially constant inner diameter.

  In addition, the sliding portion 221 is formed with an attachment hole 221A penetrating from the inner periphery to the outer periphery, and the protrusion 211D is disposed in the attachment hole 221A. Thereby, the flange part 22 is being fixed to the connection holding part 21 in the state which cannot be relatively rotated with respect to the connection holding part 21, and the removal from the connection holding part 21 was suppressed more reliably.

  The joint member 3 is formed in a cylindrical shape from a predetermined resin (for example, ABS or the like), and has an internal thread portion 3A capable of screwing the external thread portion 211A on the inner periphery of one end thereof. Then, the male screw portion 211A is screwed into the female screw portion 3A in a state where the upper surface portion 101 is sandwiched between the flange portion 22 (the flange portion 222) and the one end surface of the joint member 3, whereby the guide member 2 and The joint member 3 is fixed to the bathtub 100 (upper surface portion 101).

  Furthermore, an annular seal member 7 made of an elastically deformable material (for example, resin or rubber) is provided between the one end surface of the joint member 3 and the back surface of the upper surface portion 101 by the joint member 3 and the upper surface portion 101. It is provided in a sandwiched state. Thereby, water leakage prevention between the joint member 3 and the upper surface part 101 is achieved.

  One end of a pipe (not shown) is connected to the other end of the joint member 3. The other end of the pipe is connected to a drain pipe (not shown) provided at the drain of the bathtub 100, and the water that has entered the guide member 2 is the joint member 3, the pipe, and the It is discharged through the drain pipe.

  The operation mechanism 4 includes a support shaft 41 that extends along the direction of the central axis CL1 of the guide member 2 and that can reciprocate along the direction of the central axis CL1. The operation button 6 is attached to the support shaft 41 by inserting one end portion (upper end portion) of the support shaft 41 into a later-described attached portion 613 of the operation button 6.

  In addition, a concave constricted portion 41A extending in the circumferential direction is provided at one end of the support shaft 41. When the operation button 6 is attached to the support shaft 41, the support shaft 41 is attached to the constricted portion 41A. The convex part 613A mentioned later of the part 613 will be in the state which entered. This prevents the operation button 6 from coming off from the support shaft 41. The round hole portion may penetrate the support shaft 41.

  Further, the operation mechanism 4 includes a recessed locking portion 42 on the outer periphery thereof. Then, the operation mechanism 4 is configured such that the locking member 213 </ b> A is locked to the locked portion 42, the guide member is inserted into the inner periphery of the holding portion 213, and is seated on the holding portion 213. 2 is attached.

  The transmission member 5 is formed of, for example, a metal wire and is configured to be able to reciprocate with respect to a cylindrical outer skin 51 provided on its outer periphery. Moreover, the transmission member 5 is connected to the operation mechanism 4 at one end, and a stopper lid support mechanism (not shown) that supports the stopper lid (not shown) provided at the drain outlet of the bathtub 100 at the other end. It is connected.

  The operation button 6 is disposed on the inner periphery of the guide member 2 with the one end side surface positioned on the surface side of the upper surface portion 101. Further, the operation button 6 reciprocates together with the support shaft 41 when the one end side surface is pressed, and the outer peripheral surface thereof moves along the inner surface of the guide member 2 during the reciprocal movement. That is, the movement of the operation button 6 is guided by the guide member 2. The operation button 6 is always located on the inner periphery of the guide member 2 and does not protrude from the guide member 2.

  Further, during the reciprocal movement, the operation button 6 moves along the inner peripheral surface of the sliding portion 221 made of metal and the inner peripheral surface of the small diameter portion 211C made of resin. In other words, at least a part of a portion of the inner surface of the guide member 2 corresponding to a movement range of a cover portion 62 described later of the operation button 6 is made of metal.

  Further, the support shaft 41 moves (displaces) along with the movement (displacement) of the operation button 6, whereby the transmission member 5 reciprocates within the outer skin 51. As a result, the displacement of the operation button 6 is transmitted to the stopper lid side, and the stopper lid is moved up and down, and the drain outlet is opened and closed.

  Furthermore, in the present embodiment, the operation button 6 has a main body 61 made of a predetermined resin (for example, POM) as shown in FIGS. 2 (a) to 2 (c) and FIGS. 3 (a) to 3 (c). And a cover portion 62 made of metal (for example, aluminum or stainless steel) fixed to the main body portion 61 so as to cover one end portion of the main body portion 61.

  The main body 61 has a headed cylindrical shape, and extends from the other end of the head 611 to the other end along the head 611 located at one end of the main body 61 and the axis (center axis) CL2 of the main body 61. It has the cylindrical other end side cylinder part 612 extended toward.

  The outer diameter of the head 611 is slightly smaller than the outer diameter of the other end side cylindrical portion 612. In addition, a cylindrical attached portion 613 that protrudes toward the other end side is provided on the back surface of the head portion 611. As described above, the attached portion 613 is used for attaching the operation button 6 to the support shaft 41, and includes a convex portion 613A protruding inward. Further, the attached portion 613 has a slit portion 613B extending in the direction of the central axis CL2. When attaching the operation button 6 to the support shaft 41, the slit portion 613B is widened so that the convex portion 613A can enter the constricted portion 41A while the support shaft 41 is inserted into the attached portion 613. Can be done.

  The other end side cylinder part 612 has a recess 612A, a sliding part 612B and a shoulder 612C on its outer periphery, and an inner protrusion 612D on its inner periphery.

  The recess 612A has a hollow shape, and in the present embodiment, extends in the direction of the central axis CL2 of the main body 61 and reaches the other end of the main body 612A (from one end to the other end of the outer surface portion of the other end side cylindrical portion 612). It has a groove shape. A plurality of the recesses 612 </ b> A are provided at intervals along the circumferential direction of the main body 61. In the present embodiment, three recesses 612 </ b> A are provided at equal intervals along the circumferential direction of the main body 61.

  Further, in the present embodiment, the recesses 612A are provided asymmetrically with respect to the central axis CL2 of the main body 61, and the main body 61 is slid at a position sandwiching the central axis CL2 with the recess 612A. A portion 612B is provided.

  The sliding portion 612 </ b> B has a curved surface shape and is positioned between the concave portions 612 </ b> A adjacent to each other along the circumferential direction of the main body portion 61. The virtual surface VS including the sliding portion 612B (see FIG. 2B) is configured to have a cylindrical shape, and when the operation button 6 is reciprocated, the sliding portion 612B is moved to the guide member 2 (sliding portion). It moves along the inner peripheral surface of the part 221). The outer diameter of the other end side cylinder portion 612 mentioned above refers to the outer diameter of the virtual surface VS.

  The shoulder portion 612C is configured by one end surface of the other end side cylindrical portion 612, and is positioned between the other end of the head portion 611 and one end of the sliding portion 612B. The shoulder portion 612C has a stepped shape, and a part of the portion located outside the cover portion 62 has a flat shape extending in a direction orthogonal to the central axis CL2.

  The inner protrusion 612D is a protrusion that protrudes inward in the radial direction, and is provided corresponding to the formation position of the recess 612A along the circumferential direction of the main body 61. In the present embodiment, the inner protrusion 612D is provided at the same position as the formation position of the recess 612A along the circumferential direction of the main body 61, and is located on the back side of the recess 612A.

  The cover part 62 is formed of a thin metal plate, and has a flat plate-like exposed part 621 constituting one end face of the operation button 6 and an outer edge part of the exposed part 621 from the outer edge part to the other end side along the central axis CL2. A cylindrical tubular portion 622 extending toward the other end, and a leg portion 623 projecting from the other end portion of the tubular portion 622 toward the other end side are provided.

  The exposed portion 621 covers one end surface of the head 611 and is exposed on the surface side of the upper surface portion 101.

  The cylindrical portion 622 covers the side surface (outer peripheral surface) of the head 611. Moreover, although the cylindrical part 622 has a length of a predetermined value (for example, 2 mm) or more along the central axis CL2, and does not contact the other end side cylindrical part 612 (shoulder part 612C), The other end side cylinder portion 612 (shoulder portion 612C) extends to a position in the immediate vicinity. Therefore, the cylindrical part 622 in the present embodiment covers almost the entire side surface (outer peripheral surface) of the head 611.

  Further, the outer diameter of the cylindrical portion 622 is smaller than the outer diameter of the other end side cylindrical portion 612. Therefore, on one end side of the operation button 6, an annular gap is formed between the outer peripheral surface of the operation button 6 and the inner peripheral surface of the guide member 2. However, the said clearance gap is formed between the outer peripheral surface of the cylindrical part 622, and the internal peripheral surface of the guide member 2, and the main-body part 61 is the other end side (back side) rather than the said clearance gap (cylindrical part 622). In this case, the outer periphery of the operation button 6 is exposed. Therefore, it is difficult to visually recognize the main body 61 (resin portion) through the gap.

  A plurality of leg portions 623 are provided at equal intervals along the circumferential direction of the main body portion 61. More specifically, the leg portions 623 are provided at positions corresponding to the formation positions of the recesses 612A along the circumferential direction of the main body portion 61. In the present embodiment, the leg portions 623 are equally spaced along the circumferential direction of the cover portion 62. Three are provided.

  Further, the leg 623 is bent at the center portion along the direction of the central axis CL2 with the other end (tip) bent inward. As a result, the leg portion 623 is caulked and fixed to a portion of the main body portion 61 where the concave portion 612 </ b> A is formed. As a result, the cover portion 62 is caulked and fixed to the main body portion 61.

  Further, in the present embodiment, the outer side surfaces (outer peripheral surface) of the cylindrical portion 622 and the leg portion 623 are located on the inner peripheral side (center axis CL2 side) than the sliding portion 612B. Thereby, when the operation button 6 is reciprocated, as described above, the sliding portion 612B moves along the inner peripheral surface of the guide member 2 so that the cover portion 62 does not contact the inner peripheral surface of the guide member 2. It has become.

  Next, a method for fixing the cover 62 to the main body 61 will be described.

  First, as shown in FIGS. 4A and 4B, the main body 61 is mounted on a pedestal SE having a hollow KB on the outer periphery corresponding to the inner protrusion 612D. As a result, the main body 61 is arranged in a fixed direction and in a state in which it cannot rotate relative to the pedestal SE.

  Next, the cover 62 is disposed (covered) on the main body 61 so that the leg 623 is disposed on the recess 612 </ b> A.

  Then, as shown in FIG.4 (c), the leg part 623 is pressed and deform | transformed from the outer peripheral side of the main-body part 61 with predetermined punch PU. Accordingly, the leg portion 623 is crimped to the portion of the main body portion 61 that forms the recess 612 </ b> A, and the cover portion 62 is crimped and fixed to the main body portion 61.

  As described above in detail, according to the present embodiment, since the operation button 6 is provided with the cover portion 62, it is possible to improve the appearance quality.

  Further, in the present embodiment, the sliding portion 612B provided on the resin main body portion 61 is located on the outer peripheral side with respect to the outer surfaces of the cylindrical portion 622 and the leg portion 623, and when the operation button 6 is moved. Only the sliding portion 612 </ b> B moves along the inner surface of the guide member 2. Therefore, when the operation button 6 is moved, when the operation button 6 and the guide member 2 come into contact with each other, the resin portion (sliding portion 612B) rubs against the inner peripheral surface of the guide member 2, and noise generation is further reduced. It can be surely prevented.

  Furthermore, the cover portion 62 is fixed to the main body portion 61 by crimping a plurality of leg portions 623 provided at intervals along the circumferential direction with respect to the main body portion 61. Accordingly, it is possible to reduce the load applied to the main body 61 and the cover 62 during caulking. As a result, it is possible to more reliably prevent the main body 61 and the cover 62 from being damaged during caulking.

Therefore, for example, a convex or concave engaging portion is provided on the outer periphery of the guide member 2, and a concave or convex engaged portion that can be engaged with the engaging portion is provided on the inner periphery of the joint member 3. In a state where the bathtub 100 is sandwiched between the joint member 3 and the guide member 2, the guide member 2 is attached to the bathtub 100 by engaging the engaging portion with the engaged portion (for example, snap-fit engagement). It is good as well.

  (E) In the above embodiment, the cover portion 62 is crimped and fixed to the main body 61 by pressing and deforming the leg 623 from the outer peripheral side of the main body 61 with the punch PU. Accordingly, the cover portion 62 may be fixed by caulking to the main body portion 61 by pressing the leg portion 623 in the direction of the central axis CL2. In this case, the leg portion 623 can be pressed and deformed by moving the punch from the other end of the main body portion 61 through the recess 612A in the direction of the central axis CL2. Accordingly, it is sufficient that the punch is movable in the direction of the central axis CL2 of the main body 61. As a result, the manufacturing cost can be reduced, and the productivity can be further improved.

  (F) In the above embodiment, the operation button 6 has a cylindrical shape, but the shape of the operation button 6 is not limited to this. Therefore, for example, the operation button 6 may have a rectangular tube shape. Further, the shape of the guide member 2 may be appropriately changed according to the shape of the operation button.

  (G) The formation position of the recess 612A is not limited to that of the above embodiment, and may be changed as appropriate. Therefore, for example, the concave portion 612A may be provided symmetrically with respect to the central axis CL2 of the main body portion 61.
