Description

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

  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. As such an operation device, an operation button provided on a predetermined tank body (for example, a bathtub, a washbasin, etc.) or an object to be attached which is a structure in the vicinity thereof, and the operation button are supported in a reciprocable state. An operation mechanism having a support shaft for the operation, a guide member having an operation button arranged on the inner periphery for guiding the movement of the operation button, and a joint that holds the operation mechanism and is directly or indirectly attached to the guide member The thing provided with the mechanism is proposed (for example, refer patent document 1 grade). In general, a predetermined pipe is connected to the joint mechanism, and water that has entered from between the operation button and the guide member enters the pipe and is not leaked to the outside of the joint mechanism. Yes.

  In addition, as a joint mechanism, while holding an operation mechanism in the cylindrical outer cylinder part to which one end part of its own is connected to the attachment object, and its own inner circumference, A configuration in which a pipe is connected and has a cylindrical inner cylinder part located on the inner peripheral side of the outer cylinder part, and a hook-like connecting part connecting the other end part of the outer cylinder part and the outer periphery of the inner cylinder part; It is possible to do.

JP 2003-82731 A

  By the way, it is conceivable that the connecting portion is configured to extend in a direction orthogonal to the central axis of the joint mechanism. In this case, the central axis of the joint mechanism is inclined from the vertical direction. When the joint mechanism is attached to the guide member in a tilted state, a part of the infiltrated water is accumulated on the outer peripheral side (the part located on the lowest side) of the annular space. As a result, the infiltrated water continues to remain in the annular space, and there is a possibility that the effect of improving hygiene by providing the water passage cannot be sufficiently exhibited.

  The present invention has been made in view of the above circumstances, and its purpose is to pass through even when the joint mechanism is attached to the guide member with the central axis of the joint mechanism inclined obliquely from the vertical direction. An object of the present invention is to provide an operating device capable of more reliably discharging water that has entered a ring-shaped space through a water channel and realizing excellent hygiene.

  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.

The joint mechanism is
A cylindrical outer tube part whose one end is directly or indirectly connected to the guide member;
While holding the operation mechanism in its own inner periphery, a predetermined pipe is connected to the other end of itself, a cylindrical inner cylinder part located on the inner periphery side of the outer cylinder part, and
Having a hook-like connecting portion connecting the other end of the outer tube portion and the outer periphery of the inner tube portion;
An annular space is formed by the inner peripheral surface of the other end portion of the outer cylindrical portion, the outer peripheral surface of the one end portion of the inner cylindrical portion, and the inner side surface of the connecting portion that connects these,

  According to the above means 1, the inner side surface (the surface forming the annular space) of the connecting portion is shaped to be inclined toward the other end side of the inner cylinder portion toward the inner peripheral side. Therefore, even when the joint mechanism is attached to the guide member with the central axis of the joint mechanism tilted obliquely from the vertical direction, water may accumulate on the outer peripheral side of the annular space. It becomes difficult. As a result, water that has entered the annular space through the water passage can be discharged more reliably, and excellent hygiene can be realized.

  Moreover, since the inner side surface of a connection part becomes a shape which inclines toward the water flow path side, it can guide the infiltrated water to the water flow path side by gravity. Therefore, the performance of discharging water from the water passage can be further increased, and sanitary properties can be further improved.

Mean 2. The inner cylinder part is
A plurality of protrusions extending toward one end side from a portion where the connecting portion is connected, and supporting the operation mechanism on its inner circumference;
A claw portion extending from the portion where the connecting portion is connected toward one end side and formed on its inner periphery, and a small protrusion portion that is locked to the operation mechanism;

  The "inner diameter of the support surface" refers to the diameter of a circle that passes through the inner periphery of the support surface, centered on the central axis of the joint mechanism, and is arranged on the inner periphery of the support surface without deforming the protrusions. It can be said that the maximum outer diameter of the cylinder is possible. Further, the outer diameter of the convex portion refers to the diameter of a circle passing through the outer periphery of the convex portion with the center axis of the support shaft as the center (hereinafter the same).

  According to the above means 3, the operation mechanism is supported by the protrusion in a state where the support surface portion is disposed in the recess. Therefore, relative rotation of the operation mechanism with respect to the joint mechanism can be restricted, and the operation mechanism can be accurately attached to the joint mechanism at a certain position along the circumferential direction.

  Further, according to the above means 3, since the inner diameter of the support surface portion is made smaller than the outer diameter of the convex portion, when the operation mechanism is inserted into the inner periphery of the projection portion, it is supported with respect to the position where the convex portion is formed. It can prevent more reliably that a surface part will be arrange | positioned and by extension, a support surface part can be arrange | positioned to a recessed part more reliably.

  When the protrusion is formed of resin or the like, the protrusion can be elastically deformed to increase the diameter. For this reason, there is a possibility that the operation mechanism can be inserted to the final arrangement position with respect to the inner periphery of the protruding portion while the support surface portion is located inside the convex portion.

  In this regard, according to the means 4, the support surface portion and the convex portion are configured to extend to the vicinity of the base portion of the projection portion where deformation (expansion) hardly occurs. Therefore, when the operation mechanism is inserted into the inner periphery of the protrusion, the operation mechanism cannot be inserted to the final position when the support surface portion is disposed on the inner periphery side of the convex portion. As a result, erroneous assembly of the operation mechanism with respect to the joint mechanism can be prevented more reliably.

Means 5. The inner diameter of the support surface portion and the outer diameter of the recess are substantially equal,

  The “outer diameter of the recess” means the diameter of a circle passing through the outer periphery of the recess with the center axis of the support shaft as the center. In addition, “the inner diameter of the support surface portion and the outer diameter of the concave portion are substantially equal” is not only when the inner diameter of the support surface portion and the outer diameter of the concave portion are the same, but slightly (for example, 0.5 mm) The following also includes the case where there is a difference in diameter.

  According to the means 5, the outer peripheral surface of the concave portion can be supported by the support surface portion in a wide range along the central axis direction of the operation mechanism, and the operation mechanism can be supported in a more stable state by the projection portion. .

  Further, according to the means 5, the operation mechanism is supported by the support surface portion in the vicinity of the base portion of the projection portion which is not easily deformed.

It is supported by the protrusion 78 in an impossible state. In addition, the claw portion 79A is locked to the notch portion provided in the convex portion 52, thereby preventing the operation mechanism 5 from coming off from the joint mechanism 7 (see FIG. 2).

  Furthermore, one end of a cylindrical pipe 107 made of a predetermined resin is connected to the outer periphery of the other end of the inner cylinder 72 (see FIG. 1). The other end of the pipe 107 is connected to a pipe body 108 that is connected to the drain port 104 and serves as a drainage channel. Water that has entered the joint mechanism 7 passes through the pipe 107 and the pipe body 108. It is designed to drain to the side.

  Next, the configuration of the joint mechanism 7 will be described in detail. In this embodiment, as shown in FIGS. 4 and 5, inside the joint mechanism 7, the inner peripheral surface of the other end portion of the outer cylindrical portion 71, the outer peripheral surface of one end portion of the inner cylindrical portion 72, and the connection that connects them. An annular space SP is formed by the inner surface of the portion 73. And the water channel CA which connects the said annular space SP and the inner peripheral space of the inner cylinder part 72 is provided in the site | part to which the inner surface of the connection part 73 is connected among the inner cylinder parts 72. As shown in FIG. In this embodiment, the water passage CA is formed by gaps formed between the protrusions 78 and between the protrusions 78 and the small protrusions 79, and a plurality of water passages CA are provided intermittently along the circumferential direction. . Further, the water passage CA is formed at a position that is symmetrical with respect to the central axis of the joint mechanism 7.

  In addition, in this embodiment, the inner side surface of the connection part 73 is comprised so that it may incline to the other end side (downward side) of the inner cylinder part 72 toward an inner peripheral side. That is, it is configured such that the water that has entered the annular space SP through the inner surface of the connecting portion 73 is guided toward the water passage CA. In the present embodiment, the inclination angle of the connecting portion 73 (the smallest angle among the angles formed by the inner surface of the connecting portion 73 and a straight line perpendicular to the central axis in the cross section including the central axis of the joint mechanism 7). The inclination angle of the surface (mounting surface) to which the operating device 1 is mounted (in the cross section including the central axis of the joint mechanism 7) is the minimum angle among the angles formed by the mounting surface and a straight line extending horizontally. If it extends horizontally, it becomes 0 °). That is, even when the mounting surface is inclined, the water that has entered the annular space SP is guided to the water passage CA side along the inner side surface of the connecting portion 73 on the entire circumference of the connecting portion 73. It has become.

  Furthermore, the operating mechanism 5 and the protrusion 78 that supports the operating mechanism 5 are configured as follows. That is, as shown in FIG. 6, the inner diameter D1 of the support surface portion 78A is smaller than the outer diameter D2 of the convex portion 52. Further, the inner diameter D1 of the support surface portion 78A and the outer diameter D3 of the concave portion 53 are substantially equal. The inner diameter D1 of the support surface portion 78A refers to the diameter of a circle C1 centering on the central axis of the joint mechanism 7 and passing through the inner periphery of the support surface portion 78A. The outer diameter D2 of the convex portion 52 refers to the diameter of a circle C2 that passes through the outer periphery of the convex portion 52 with the central axis of the support shaft 51 as the center. Furthermore, the inner diameter D3 of the recess 53 refers to the diameter of a circle C3 that passes through the outer periphery of the recess 53 with the center axis of the support shaft 51 as the center.

  In addition, as shown in FIGS. 2 and 4, the support surface portion 78 </ b> A and the convex portion 52 (with respect to the convex portion 52 in a state where the operation mechanism 5 is normally attached to the joint mechanism 7) are at least the base portion of the projecting portion 78. It is configured to extend to the vicinity. The “base of the protrusion 78” refers to the root of the protrusion 78. In addition, “the vicinity of the base of the protrusion 78” means that, when a force is applied from the inner peripheral side to the outer peripheral side of the protrusion 78, there is almost no bending deformation to the outer peripheral side. A part that can ensure rigidity. For example, the distance from the base of the protrusion 78 to the position of about 10 mm from the base toward the tip of the protrusion 78 can be referred to as the vicinity of the base of the protrusion 78. In addition, it is preferable that the support surface part 78A and the convex part 52 (in a state where the operation mechanism 5 is normally attached to the joint mechanism 7) extend to a position where the deformation to the outer peripheral side is less likely to occur in the protrusion part 78 ( That is, the closer to the base of the protrusion 72, the better. Therefore, it is more preferable that the support surface portion 78A and the convex portion 52 extend from the base portion of the projecting portion 78 toward the distal end of the projecting portion 78 toward the base side rather than the position of 6 mm. It is even more preferable that it extends toward the base side than the position of 3 mm toward the tip of 78.

  Further, in the present embodiment, the concave portion 53 (in a state where the operation mechanism 5 is normally attached to the joint mechanism 7) is configured to extend at least to the vicinity of the base portion of the protruding portion 78, like the support surface portion 78A.

  As described above in detail, according to the present embodiment, the inner side surface (surface that forms the annular space SP) of the connecting portion 73 is inclined toward the other end side of the inner cylindrical portion 72 toward the inner peripheral side. It is said that. Therefore, even when the joint mechanism 7 is attached to the guide member 2 with the central axis of the joint mechanism 7 inclined obliquely from the vertical direction, water accumulates on the outer peripheral side of the annular space SP. Such a situation is less likely to occur. As a result, water that has entered the annular space SP via the water passage CA can be discharged more reliably, and excellent hygiene can be realized.

  Further, the water that has entered the annular space SP through the inner surface of the connecting portion 73 can be guided toward the water passage CA by gravity. Therefore, the performance of discharging water from the water passage CA can be further increased, and further improvement in hygiene can be achieved.

  In addition, a plurality of gaps formed intermittently along the circumferential direction are formed between the protrusions 78 and the small protrusions 79, and a water passage CA is formed by the gaps. Therefore, the water flow area of the water flow channel CA can be effectively increased, and the drainage capacity can be further enhanced. As a result, further improvement in hygiene can be achieved.

  Furthermore, the operation mechanism 5 is supported by the protrusion 78 in a state where the support surface portion 78 </ b> A is disposed in the recess 53. Therefore, relative rotation of the operation mechanism 5 with respect to the joint mechanism 7 can be restricted, and the operation mechanism 5 can be accurately attached to the joint mechanism 7 at a certain position along the circumferential direction.

  In addition, since the inner diameter D1 of the support surface part 78A is smaller than the outer diameter D2 of the convex part 52, when the operating mechanism 5 is inserted into the inner periphery of the projecting part 78, the position where the convex part 52 is formed. The support surface portion 78A can be more reliably prevented from being disposed, and as a result, the support surface portion 78A can be more reliably disposed in the recess 53. Accordingly, it is possible to more reliably prevent the operation mechanism 5 from being attached to an incorrect position in the circumferential direction when attached to the joint mechanism 7.

  Further, the support surface portion 78A and the convex portion 52 are configured to extend to the vicinity of the base portion of the protruding portion 78 that is hardly deformed (expanded diameter). Therefore, when the operation mechanism 5 is inserted into the inner periphery of the protrusion 78, the operation mechanism 5 is inserted to the final arrangement position in a state where the support surface portion 78A is disposed on the inner periphery side of the convex portion 52. Can not be. As a result, erroneous assembly of the operation mechanism 5 with respect to the joint mechanism 7 can be prevented more reliably.

  Further, the support surface portion 78 </ b> A and the recessed portion 53 are configured to extend at least to the vicinity of the base portion of the protruding portion 78. Accordingly, the outer peripheral surface of the concave portion 53 can be supported by the support surface portion 78A in a wide range along the central axis direction of the operation mechanism 5, and the operation mechanism 5 can be supported in a more stable state by the projection portion 78. . In addition, since the operation mechanism 5 is supported by the support surface portion 78A in the vicinity of the base of the protrusion 78 that is unlikely to be deformed, the operation mechanism 5 is more reliably prevented from being inclined due to the deformation of the protrusion 78. it can.

  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) Configurations of the cylindrical member 3, the joint mechanism 7 and the like in the above embodiment are examples, and these configurations are not particularly limited. Therefore, for example, when connecting the tubular member 3 and the joint mechanism 7, both may be configured such that the joint mechanism 7 is screwed to the tubular member 3.

  (B) In the above embodiment, the joint mechanism 7 is indirectly connected to the guide member 2 via the tubular member 3, but the joint mechanism 7 is directly connected to the guide member 2. Also good. Therefore, for example, the cylindrical member 3 is omitted, and a concave locked portion is provided on the outer periphery of the guide member 2 (main body portion 22) instead of the male screw portion 21, and a ring member is provided with respect to the locked portion. The inner peripheral portion 82 of the eight may be locked.
