Abstract

PROBLEM TO BE SOLVED: To prevent damage of a valve member or the like and the injury of a user by composing the shaft part of an valve member out of an upward cylindrical part and a downward cylindrical part movably engaged with the upward cylindrical part in the direction of an axial core, and providing an elastic member for urging both the cylindrical parts so as to wider the space between them. SOLUTION: The shaft part of a valve member 1 is composed of an upward cylindrical part 3a and a downward cylindrical part 3b movably engaged with the upward cylindrical part 3a in the direction of an axial core, and a spring member 4a as an elastic member urged so as to widen a part between both the cylindrical parts 3a, 3b between the upward and downward cylindrical parts 3a, 3b is provided. It can be prevented to strike a hand of a user or the like to a projected valve member 1 in the opening state of a remote controlled drainer and to damage the valve shaft, a valve opening and closing operation part and a valve fixing part or get hurt for the user because the spring member 4a of the valve member 1 is contracted and retracted to lower a valve body 2 and the applied stress is absorbed even if stress is applied on the valve member 1 by mounting a matter on the valve body 1 and collecting water.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remotely operated drainage device mounted on a bathtub, a wash basin or the like, and more particularly to an improvement in a valve member used in a remotely operated drainage device.

[0002]

2. Description of the Related Art Conventionally, bathtubs, washstands and the like have been used without directly touching a water stop valve member provided at a drain port.
2. Description of the Related Art Remotely operated drainers that can open and close a valve member by operating an operation switch are used.

Conventionally well-known remote-operated drainers include, for example, those shown in FIGS. The remote-operated drainage device shown in FIGS. 4 to 7 has a valve member including a valve body and a shaft portion, and a drainage body portion having a drainage port closed by the valve portion when the valve member descends. When,
An operation switch for operating the opening and closing of the valve member by pushing in, a valve opening and closing operation unit having an arm portion for raising and lowering the valve member in response to operation of the operation switch, and until the next operation is performed at the time of opening operation A valve fixing portion provided with a thrust lock member for maintaining and fixing the arm portion in a raised state, and a wire portion connecting the valve opening / closing operation portion and the operation switch via the valve fixing portion, and holding the wire portion and the wire portion so as to be able to move forward and backward. And an operation transmitting member formed of a release wire formed of an outer tube. In addition, the thrust lock member mentioned here receives the forward / backward movement of the wire portion generated by the operation of the operation switch, and for each operation of the wire portion,
It is a member that repeats fixing / unlocking and lowering the arm portion with the arm portion raised.

In the case of using a remote-controlled drainage device having the above structure, the remote-controlled drainage device is attached to a wash basin or the like in a watertight manner, and then the drainage device is opened as shown in FIG. . In this state, the thrust lock member is fixed in a state where the arm portion on which the shaft portion of the valve member is mounted is pushed upward. When operating the operation switch from this state,
As the wire portion of the release wire advances and retreats, the fixing of the arm portion by the thrust lock member is released, the arm portion is lowered, and accordingly, the valve member is lowered while mounted on the arm portion, as shown in FIG. The valve body of the valve member closes the drain port. When the operation switch is further operated from the state in which the drain port is closed, the thrust lock member is again fixed in a state where the arm portion is raised, and the shaft portion of the valve member rises while mounted on the arm portion, and the drain port is raised. The valve body can be further pushed up to open the drain port.

[0005]

By the way, when a user uses a wash basin or the like employing the above-mentioned remote-controlled drainage device, if the drainage port is open, the user's hand or the like will protrude. Frequently, there is a case where the water hits a valve member, or a bucket or the like is placed on a protruding valve member to store water. In the case described above, stress is applied to the valve member from above or the like, but since the valve member is fixed to the valve fixing portion via the arm portion of the valve opening / closing operation portion, the stress is dispersed and absorbed. Without receiving the stress as it was. For this reason, if the applied stress is large, the shaft portion of the valve member is bent, or the thrust lock member of the valve fixing portion and the arm portion of the valve opening / closing operation portion are damaged.
In some cases, the user's hand hitting the valve member may be injured. The present invention has been made to solve the above problems.

According to the first aspect of the present invention, there is provided a remotely operated drainage device according to the present invention, comprising a valve body (2) and a shaft (3).
A drain member body (5) having a drain port (6) closed by a valve element (2) when the valve member (1) is closed, and a valve member (1). An operation switch (7) for operating the opening / closing operation of the valve, a valve opening / closing operation section (8) that operates in response to the operation of the operation switch (7), and opens and closes a drain port of the valve member (1); An operation transmission member (9) for connecting the switch (7) and the valve opening / closing operation section (8) to transmit the operation of the operation switch (7) to the valve opening / closing operation section (8), and a drain port (6). A valve fixing portion (10) for maintaining and fixing the valve member (1) in that state in at least one of the open state and the closed state until the operation switch (7) is operated; In the above, the shaft portion (3) of the valve member is connected to an upper tubular portion (3a) and the upper tubular portion (3a). And constructed from a lower tube portion engaged to advance and retreat freely (3b) with respect to the axial direction, further the both tubular portions (3a, 3b) between both the cylindrical portion (3a,
A remote-controlled drainage device comprising an elastic member (4) for urging the space between 3b) to expand.

According to a second aspect of the present invention, in the remote-operated drainage device, the elastic member (4) used for the valve member (1) is made of a spring material (4a). It is a remote-controlled drainage device.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. The embodiment of the present invention shown in FIGS. 1 and 2 includes a valve body (2) and an upper cylinder (3) as shown in FIG.
a) and a shaft portion (3) composed of the upper tube portion (3a) and a lower tube portion (3b) engaged so as to freely move back and forth in the axial direction. )
a, 3b), a valve member (1) including a spring member (4a) as an elastic member (4) for urging the two cylindrical portions (3a, 3b) to expand, and a valve member (1). (6) The drain port (6) closed by the valve body (2) during the closing operation in which
, A switch body (5) for opening and closing the valve member (1) by a pushing operation, and raising and lowering the valve member (1) in response to the operation of the operation switch (7). A valve opening / closing section (8) having an arm section (8a) that moves up and down, and a thrust lock member (10a) that maintains the arm section (8a) in a state of being pushed up until the next operation is performed during the opening operation. The wire (9b) and the wire (9b) which connect the operation switch (7) and the valve opening / closing unit (8) via the valve fixing part (10) provided with the valve fixing part (10). And an operation transmitting member (9) formed of a release wire (9a) composed of an outer tube (9c) freely held. In the shaft portion (3) of the valve member (1), the cylindrical portion is a concept indicating a rod-like body optionally including a hollow portion. Therefore, the upper cylindrical part (3
