JP 2009-57687 A

  However, in the above method, it is necessary to provide a mounting hole and a slit at the end of the operation shaft, but the processing for providing the mounting hole and the slit on the metal operation shaft is not easy. . In particular, it is difficult to form the slit portion in which the transmission member is arranged because the width is relatively narrow. For this reason, there is a possibility that an increase in manufacturing cost and a decrease in productivity may be caused.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an operation device capable of easily connecting an operation shaft and a transmission member while reducing manufacturing cost and improving productivity. Is to do.

  Hereinafter, each means suitable for solving the above-mentioned object will be described in terms of items. In addition, the function and effect peculiar to the corresponding means will be added if necessary.

Means 1. A cylindrical guide member,
A reciprocally movable operation shaft inserted through the inner periphery of the guide member,
A transmission member that transmits a driving force due to the displacement of the operation shaft to a stopper provided on a drain port of the tank body,
A terminal connection portion attached to an outer periphery of an end of the transmission member and protruding from an outer periphery of the transmission member,
At the end of the operating shaft,
A mounting hole that has a mounting opening through which the terminal connection portion can pass on the outer peripheral surface of the end portion, and the terminal connection portion is configured to be able to be arranged through the mounting opening,
The outer peripheral surface has a slit opening through which the transmission member can pass, and is formed with a slit portion that communicates with the mounting hole portion and is configured to be able to dispose the transmission member through the slit opening. And
An operation in which the transmission member is arranged in the slit portion and the terminal connection portion is arranged in the mounting hole, and the operation shaft and the transmission member are connected. A device,
The operation axis is
A rod-shaped shaft main body made of metal;
An operating device, which is connected to an end of the shaft main body and has a resin-made terminal formed with the mounting hole and the slit.

  According to the above means 1, the operation shaft and the transmission member can be easily connected by a simple method of arranging the terminal connection portion in the mounting hole while arranging the transmission member in the slit portion.

  Further, according to the first aspect, the operation shaft includes a terminal portion made of resin, and the mounting portion and the slit portion are formed in the terminal portion. Therefore, compared to the case where the mounting hole and the slit are provided on the metal component, the processing for providing the mounting hole and the slit can be facilitated, and the slit is difficult to form. Can also be easily provided. As a result, the manufacturing cost can be reduced and the productivity can be improved.

  Means 2. The operating device according to claim 1, wherein the terminal portion has a bottom portion that prevents the terminal connection portion disposed in the mounting hole portion from coming off on a side opposite to the mounting opening portion.

  The “bottom” may be any as long as it can prevent the terminal connection portion from coming off, and is not limited to the one that closes the mounting hole on the side opposite to the mounting opening. Therefore, the “bottom portion” is, for example, a protrusion (step) protruding inward and a bridge-like portion connecting the opposing inner peripheral surfaces provided on the inner peripheral surface of the portion forming the mounting hole. And so on.

  It is conceivable that the mounting hole has, for example, a shape with a bottom that penetrates the terminal portion. However, in this case, when arranging the terminal connecting portion to the mounting hole through the mounting opening, there is a possibility that the terminal connecting portion may fall out through the mounting hole, and the assembling work may not be performed. You need to be careful.

  In this regard, according to the means 2, the terminal portion has the bottom portion, and the bottom portion prevents the terminal connection portion disposed in the mounting hole portion from coming off to the side opposite to the mounting opening portion. Can be. Therefore, when the terminal connecting part is arranged in the mounting hole through the mounting opening, the terminal connecting part does not drop out of the mounting hole. Thereby, the assembling work can be performed more easily, and the productivity can be further improved.

  Means 3. 3. The operating device according to claim 1, wherein the terminal portion has a relief portion in which an end portion of the transmission member can be arranged. 4.

  According to the above-described means 3, the terminal portion is provided with a relief portion (a clearance space) in which the end portion of the transmission member can be arranged. Therefore, even if the extreme end of the transmission member protrudes from the terminal connection part, the extreme end does not hinder the arrangement of the terminal connection part in the mounting hole. Therefore, the end portion of the transmission member may be left in a state protruding from the terminal connection portion. Accordingly, it is necessary to perform a processing process (for example, a process of cutting and cutting the end portion protruding from the terminal connection portion) so that the end portion of the transmission member does not protrude from the terminal connection portion. Disappears. Further, it is not necessary to prepare expensive equipment for performing the processing. As a result, it is possible to more effectively reduce manufacturing costs and improve productivity.

  It is difficult to form the escape part in the metal part as in the case of forming the slit part in the metal part. However, since the terminal part is made of resin, the escape part can be easily formed. That is, making the terminal portion made of resin is effective even when the configuration of the means 3 is adopted.

  Means 4. The length of the mounting hole along the axial direction of the operation shaft is the same as the length of the terminal connecting portion along the axial direction of the transmission member. The operating device according to any one of the above.

  In addition, the term “identical” means not only the case where they are strictly identical but also the case where they are almost identical (for example, a region where the mounting hole is formed to such an extent that a good operation response can be secured). The case where a slight gap is formed between the terminal connecting portion and the like) is also included.

  According to the above-mentioned means 4, the length of the mounting hole along the axial direction of the operation shaft is the same as the length of the terminal connecting portion along the axial direction of the transmission member. Therefore, the relative movement of the terminal connection unit with respect to the terminal unit along the axial direction of the operation shaft can be restricted. That is, it is possible to provide a state in which there is almost no play between the terminal unit and the terminal connection unit along the axial direction of the operation shaft. Therefore, the driving force due to the displacement of the operation shaft can be more reliably transmitted to the transmission member without loss, and the operation timing of the transmission member can be more reliably prevented from being delayed from the operation timing of the operation shaft. As a result, the operation response can be increased, and the operability can be improved.

  When the length of the mounting hole is the same as the length of the terminal connecting portion, the outermost end of the transmitting member is accommodated in the mounting hole when the end of the transmitting member is protruding from the terminal connecting portion. However, there is a concern that the arrangement of the terminal connecting portion with respect to the mounting hole may be hindered. However, by employing the above-described means 3, such a concern can be eliminated. Therefore, when adopting the configuration of the means 4, it is preferable to adopt the configuration of the means 3 together.

Further, between the outer peripheral surface of the operation shaft 41 and the inner peripheral surface of the guide member 2, an annular seal member 9 made of an elastically deformable material is provided in a state sandwiched between both surfaces. The seal member 9 prevents water that has entered between the operation shaft 41 and the guide member 2 from leaking to the transmission member 5 side. The detailed configuration of the operation shaft 41 and the manner in which the transmission member 5 is connected to the operation shaft 41 will be described later.

  The transmission member 5 is made of, for example, a wire, and transmits the driving force generated by the displacement of the operation shaft 41 to a stopper (not shown) provided at a drain (not shown) of the basin 100. Is what you do. The transmission member 5 is arranged on the inner periphery of the tubular tube member 7, and reciprocates with respect to the tube member 7 with the displacement of the operation shaft 41. At the end of the tube member 7, there is provided a flare portion 71 formed by flare processing or the like and protruding radially outward.

  Further, an end of the transmission member 5 is exposed from an end of the tube member 7, and a flange-shaped terminal connecting portion 8 protruding from the outer periphery is fitted into an outer periphery of the end. In the present embodiment, the end of the transmitting member 5 is in a state of protruding from the terminal connecting portion 8.

  The closing member 6 is attached to the guide member 2 and has a function of preventing the operation member 4 from projecting from the other end of the guide member 2 while holding the end of the tube member 7. The closing member 6 includes a lid portion 61 and a holding portion 62.

  The lid 61 is provided at a position to close the other end side opening of the guide member 2 and prevents the operation member 4 from projecting from the other end of the guide member 2. The lid portion 61 is formed in a cylindrical shape by combining a pair of half portions (for example, one half portion is locked to the other half portion), and has its own shape. It has an insertion hole 61A extending in the central axis direction. The insertion hole 61A is an arrangement space for the transmission member 5 and the tube member 7, and is provided at a substantially central portion of the insertion hole 61A along the central axis of the lid portion 61 in a groove-like flare arrangement extending in the circumferential direction of the insertion hole 61A. A portion 61B is formed. And the flare part 71 is arrange | positioned with respect to the flare arrangement part 61B. Thereby, the end of the tube member 7 is held by the lid 61 in a state where the end of the tube member 7 along the axial direction of the tube member 7 is regulated.

  The holding section 62 holds the lid section 61 at a position that closes the opening at the other end of the guide member 2. The holding portion 62 has a cylindrical shape, and has a second female screw portion 62A located on one end side and a step portion 62B located on the other end side formed on the inner periphery thereof. The second male screw portion 21B is screwed to the second female screw portion 62A, and as a result, the closing member 6 is attached to the guide member 2. The step portion 62B is an annular protrusion protruding toward the central axis of the holding portion 62, and the lid portion 61 is locked to the step portion 62B. The step part 62B holds the lid part 61 by sandwiching the lid part 61 with the guide member 2. The opening on the outer peripheral side of the lid 61 in the insertion hole 61A is closed by the holding portion 62 disposed on the outer periphery of the lid 61, so that the flare portion 71 does not come off from the flare arrangement portion 61B.

  Next, a detailed configuration of the operation shaft 41 and a connection mode of the transmission member 5 to the operation shaft 41 will be described. As shown in FIGS. 1 and 2, the operation shaft 41 has a configuration including a shaft main body 411 and a terminal 412.

  The shaft main body portion 411 is formed in a rod shape (column shape) with a predetermined metal (for example, a metal having excellent corrosion resistance), and the knob portion 42 is attached to one end thereof. A shoulder 411A, a neck 411B, and a head 411C are formed on the other end of the shaft body 411 in this order toward the other end. The shoulder 411A and the head 411C are formed to have a larger diameter than the neck 411B.

  The terminal section 412 is formed of a predetermined resin, unlike the shaft body section 411. The terminal portion 412 has a shape such that two dents are formed side by side along its own axial direction, and a neck arrangement portion 412A and a head arrangement portion 412B that form one dent and the other dent are formed. It has a relief part 412C to be formed, a mounting hole part 412D, and a slit part 412E.

  Neck arrangement portion 412A has a width corresponding to the outer diameter of neck portion 411B, and is open at one end surface of terminal portion 412. The head arrangement part 412B is adjacent to the neck arrangement part 412A and has a width corresponding to the outer diameter of the head part 411C. And the neck part 411B is arrange | positioned with respect to the neck arrangement part 412A, and the head 411C is arrange | positioned with respect to the head arrangement part 412B. Thus, the shaft main body 411 and the terminal 412 are connected.

  In the present embodiment, the length of the neck arrangement portion 412A along the axial direction of the terminal portion 412 is equal to the distance between the shoulder portion 411A and the head portion 411C along the axial direction of the shaft main body portion 411 (that is, the neck portion 411B). Length). Therefore, in a state where the shaft main body 411 and the terminal 412 are connected, the part of the terminal 412 forming the neck arrangement part 412A contacts both the shoulder 411A and the head 411C and is sandwiched by both. It has become. As a result, the relative movement of the terminal portion 412 with respect to the shaft main portion 411 along the axial direction of the operation shaft 41 is regulated, so that the force is transmitted from the shaft main portion 411 to the terminal portion 412 without loss. .

  The escape portion 412C is a space having a width corresponding to the outer diameter of a portion of the transmission member 5 that protrudes from the terminal connection portion 8 (that is, the end portion of the transmission member 5).

  The mounting hole 412D is a space having a mounting opening 412F (see FIG. 2) corresponding to the outer periphery of the terminal portion 412. The mounting hole 412 </ b> D has a width corresponding to the outer diameter of the terminal connection part 8. Further, the length of the mounting hole 412 </ b> D along the axial direction of the operation shaft 41 is the same as the length of the terminal connection portion 8 along the axial direction of the transmission member 5.

  Further, the mounting hole 412D has a shape that does not penetrate the terminal portion 412, and the opposite side of the mounting opening 412F in the mounting hole 412D is in a closed state. That is, the terminal section 412 includes a bottom 412H (see FIG. 2) corresponding to the bottom of the mounting hole 412D.

  The slit section 412E is a space having a slit opening section 412G (see FIG. 2) corresponding to the outer periphery of the terminal section 412. The slit portion 412E has a width corresponding to the transmission member 5, and is opened at the other end surface of the terminal portion 412.

The end of the transmission member 5 and the terminal connection portion 8 are arranged in the escape portion 412C, the mounting hole portion 412D, and the slit portion 412E. That is, the extreme end of the transmitting member 5 is disposed with respect to the escape portion 412C, the terminal connecting portion 8 is disposed with respect to the mounting hole 412D, and the slit 412E is opposite to the distal end of the transmitting member 5 with respect to the slit portion 412E. On the side, a portion adjacent to the terminal connection portion 8 is arranged. Thus, the transmission member 5 is connected to the operation shaft 41. Note that, due to the presence of the bottom portion 412H, the terminal connection portion 8 arranged in the mounting hole portion 412D does not come off on the opposite side to the mounting opening portion 412F. The openings of the neck arrangement part 412A and the head arrangement part 412B, the relief part 412C, the mounting hole part 412D and the slit part 412E) are closed by the guide member 2, respectively. Therefore, the terminal portion 412 does not come off from the shaft main body portion 411, and the transmission member 5 and the terminal connection portion 8 do not come off from the operation shaft 41 (terminal portion 412).

  The terminal section 412 can be obtained, for example, by molding using a predetermined mold.

  Next, a method of attaching the operation device 1 to the basin 100 will be described.

  First, after the guide member 2 is inserted into the through hole 102, the inner periphery of the nut member 3 is brought into contact with the first male screw portion 21A through the guide member 2 from the other end side of the guide member 2. By rotating the nut member 3 in this state, the first male screw portion 21A is screwed with the first female screw portion 3A, and the flange portion 101 is sandwiched between the flange portion 22 and the nut member 3. Thus, the guide member 2 is attached to the flange portion 101 as shown in FIG.

  Next, after the seal member 9 is arranged on the outer periphery of the shaft main body 411, the shaft main body 411 is inserted into the inner periphery of the guide member 2 only to some extent from the other end side opening, and at least the neck 411 </ b> B of the shaft main body 411. And the head 411C protrudes from the other end of the guide member 2. Then, the terminal section 412 is connected to the shaft main body section 411 by, for example, arranging the head section 411C on the head arrangement section 412B. Further, the terminal connecting portion 8 is disposed through the mounting opening 412F to the mounting hole 412D, and the transmitting member 5 is disposed through the slit opening 412G to the slit portion 412E. 5 is connected. At this time, the foremost part of the transmission member 5 is disposed to the escape part 412C. Before connecting the transmission member 5 to the terminal portion 412, the halves constituting the lid portion 61 are combined so as to sandwich the flare portion 71, and the flare portion 71 is disposed in the flare disposition portion 61B. The cover 61 is disposed on the outer periphery of the member 7, and the transmission member 5 and the tube member 7 are passed through the inner periphery of the holding portion 62, so that the lid 61 and the holding portion 62 are disposed outside the transmission member 5 and the like in advance. It has been done.

  Then, as shown in FIG. 4, the terminal portion 412 is inserted through the inner periphery of the guide member 2. As a result, the two recesses (the head arrangement portion 412B, the mounting hole portion 412D, and the like) in the terminal portion 412 are closed by the guide member 2, and as a result, the shaft body portion 411, the terminal portion 412, and the transmission member 5 are adjacent to each other. The parts are connected in series without being separated from each other.

  Before inserting the shaft body 411 into the guide member 2, the shaft body 411, the terminal 412, and the transmission member 5 are connected in series, and thereafter, the shaft body 411 and the terminal 412 are connected to the guide member 2. May be inserted into the inner circumference of the.

  Next, the holding portion 62 previously arranged on the outer periphery of the transmission member 5 or the like is moved to the nut member 3 side to lock the lid portion 61 on the step portion 62B, and the inner periphery of the holding portion 62 The second male screw portion 21B is brought into contact. Then, by rotating the holding portion 62, the second male screw portion 21B is screwed with the second female screw portion 62A, and the holding portion 62 is attached to the guide member 2. As a result, as shown in FIG. 5, the lid 61 is sandwiched between the guide member 2 and the stepped portion 62B, and the guide member 2 is held while the tube member 7 is held by the closing member 6 (the lid 61 and the holding portion 62). Close the other end opening. It should be noted that the cover member 61 and the holding portion 62 are not arranged beforehand on the outer periphery of the transmission member 5 or the like before the holding portion 62 is attached to the guide member 2. The lid 61 and the holder 62 may be arranged on the outer periphery of the fifth and the like.

  Finally, the knob 42 is screwed to one end of the shaft main body 411 projecting from the guide member 2. As a result, the attachment of the operating device 1 to the basin 100 is completed.

  As described in detail above, according to the present embodiment, the operation shaft 41 and the transmission shaft 5 are transmitted by a simple method of disposing the terminal connection portion 8 in the mounting hole 412D while disposing the transmission member 5 in the slit portion 412E. The members 5 can be easily connected.

  Further, the operation shaft 41 includes a terminal portion 412 made of resin, and a mounting hole portion 412D and a slit portion 412E are formed in the terminal portion 412. Therefore, as compared with the case where the portion where the mounting hole and the slit are provided is made of a metal part, the processing for providing the mounting hole 412D and the slit 412E can be made easier, and the forming process can be simplified. Even the difficult slit portion 412E can be easily provided. As a result, the manufacturing cost can be reduced and the productivity can be improved.

  In addition, since the bottom portion 412H exists, when the terminal connecting portion 8 is disposed in the mounting hole portion 412D, a situation in which the terminal connecting portion 8 falls out through the mounting hole portion 412D does not occur. Thereby, the assembling work can be performed more easily, and the productivity can be further improved.

  Further, the length of the mounting hole 412 </ b> D along the axial direction of the operation shaft 41 is the same as the length of the terminal connection portion 8 along the axial direction of the transmission member 5. Therefore, the relative movement of the terminal connection part 8 with respect to the terminal part 412 along the axial direction of the operation shaft 41 can be restricted, and the terminal part 412 and the terminal connection part 8 can be restricted along the axial direction of the operation shaft 41. There can be little rattling. Therefore, the driving force due to the displacement of the operation shaft 41 can be more reliably transmitted to the transmission member 5 without loss, and the operation timing of the transmission member 5 can be more reliably delayed with respect to the operation timing of the operation shaft 41. Can be prevented. As a result, the operation response can be increased, and the operability can be improved.

  Further, in the present embodiment, since the length of the neck arrangement portion 412A is substantially equal to the distance between the shoulder portion 411A and the head portion 411C, the terminal portion 412 with respect to the shaft body portion 411 along the axial direction of the operation shaft 41. Relative movement can be restricted. Therefore, the operability can be effectively improved in combination with the above-described operation and effect.

  On the other hand, assuming that the length of the mounting hole 412D is the same as the length of the terminal connection portion 8, when the end of the transmission member 5 protrudes from the terminal connection portion 8 as in this embodiment, It is feared that the end cannot be accommodated in the mounting hole 412D, which may hinder the arrangement of the terminal connecting portion 8 with respect to the mounting hole 412D. Is formed with a relief portion 412C for arranging the end portion of the transmission member 5. For this reason, the outermost end of the transmission member 5 does not hinder the placement of the terminal connection portion 8 in the mounting hole 412D. Thereby, the end portion of the transmission member 5 may remain in the state of protruding from the terminal connection portion 8, and a processing process for preventing the end portion of the transmission member 5 from protruding from the terminal connection portion 8 (for example, (E.g., cutting off the end portion that protrudes from the terminal connection section 8 and then shaving). Further, it is not necessary to prepare expensive equipment for performing the processing. As a result, it is possible to more effectively reduce manufacturing costs and improve productivity.

  In addition, it is difficult to form the escape portion in the metal component as in the case of forming the slit portion in the metal component. However, since the terminal portion 412 is made of resin, the escape portion 412C can be easily formed. it can. That is, making the terminal portion 412 made of resin is also effective in forming the escape portion 412C.

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

  (A) In the above embodiment, the bottom portion 412H is provided so as to close the mounting hole portion 412D, but the bottom portion prevents the terminal connection portion 8 from coming off to the side opposite to the mounting opening portion 412F. Any material that can be used may be used, and it is not always necessary to close the mounting hole 412D. Therefore, the bottom portion is, for example, a projection (step) portion protruding inwardly provided on the inner peripheral surface of a portion forming the mounting hole portion 412D, a bridge-like portion connecting the opposing inner peripheral surfaces, and the like. It may be.

  (B) The method of connecting the terminal section 412 to the shaft main body section 411 is not limited to the above embodiment. Therefore, for example, a male screw may be provided on one of the shaft main body portion 411 and the terminal portion 412, a female screw may be provided on the other of the two, and the male screw may be screwed into the female screw to connect the two. Alternatively, both may be connected by locking (engaging) one of the two with the other.

  (C) In the above embodiment, the operating device 1 is attached to the basin 100, but the mounting target of the operating device 1 is not limited to this. For example, the operating device 1 may be attached to a tub body (for example, a bathtub or a sink) other than the basin. Further, the operating device 1 may be attached to a structure provided near the tank body (for example, a counter provided near the washbasin or a counter of a sink).
