DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain plug device for remotely opening and closing a valve attached to a drain port formed at the bottom of a water tank such as a bathtub or a washing tub. The present invention relates to an improvement of a drain plug device having a structure for transmitting a valve to a valve body.

[0002]

2. Description of the Related Art A drain plug device for remotely opening and closing a valve attached to a drain port provided at the bottom of a water bath such as a bathtub or a wash tub is known from Japanese Utility Model Publication No. 7-38420. Have been. Japanese Patent Application Laid-Open No. 8-302780 is known as an example of the above-mentioned remote-operated drain plug device in which a drain catch is provided with a hair catcher.

[0003] The hair catcher disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 8-302780 has a crown-shaped body that covers a guide cylinder that supports and moves up and down a valve body, and a large number of radially protruding from the outer peripheral surface of the crown-shaped body. A fin and a band which communicates the tips of the fins with each other and extends in an arc shape along the inner peripheral surface of the casing; and the hair catcher includes a bracket (the mounting blade of the present invention). ) Is provided.

[0004]

The above-mentioned JP-A-8-30
The drain plug device of No. 2780 covers the hair catcher from above with respect to the guide cylinder that supports the valve body and moves up and down.
The hair catcher has a structure in which a valve body is inserted into an insertion opening formed in the upper end surface of the coronal body and is attached to a drain plug. In this structure, when a strong operating force is transmitted from the operation unit to the valve body via the wire, the valve body may be urged by the normal upward movement of the valve body and may be pulled out.

Further, in the above invention, an arc-shaped band as a component of the hair catcher extends along the inner peripheral surface of the casing, and the slit is associated with a bracket (corresponding to a mounting blade of the present invention). It says that the hair catcher does not move inside the drain cock and does not rattle. However, if the engagement with the bracket is firm, it is difficult to remove the hair catcher, so the hair catcher is loosely fitted to the bracket, and therefore, the hair catcher rotates in the drain cock. Until then, it is impossible to forbid some rattling and the accompanying noise. The present invention has been made to solve these drawbacks.

[0006]

According to a first aspect of the present invention, there is provided a drainage plug device, wherein a drainage plug installed at a drainage opening formed at the bottom of a water tank and the drainage plug is remotely operated via an operation wire (9). and an operation section that allows (12), the drainage plug, cylinder

(8) When a plurality of protrusions (8a) are formed on the inner peripheral surface,
In both cases, a hair catcher (2) is provided in the casing (8), and the hair catcher (2) covers the guide cylinder (7) from above and supports the valve body (1). (1a) is stored therein, and a columnar body (3) having a hook (3a) formed at the upper end so as to be engaged with the lower end of the valve shaft (1a); and a radially extending outer surface of the columnar body (3). A plurality of protruding fins (4) and an arc-shaped band (5) covering the tip of the fins (4) and extending along the inner peripheral surface of the casing (8); characterized in that the slit (6) Ru formed by providing a plurality of locations for installed before described Katsubasa (10) upper surface through projections projecting from the (8a) into (8) peripheral surface is there.

[0007]

The present invention is constructed as described above, and when it is used, in a casing (8) screwed into a drain opening formed in the bottom of the water tank, the hair is placed without the valve (1) installed. The columnar body (3) of the catcher (2) is extended from the inner peripheral surface of the casing (8) in the centripetal direction by the mounting wing (1).
The guide tube (7) is supported by the guide tube (0) and connected at its end to one end of an operation wire (9) extending from the operation portion (12). After being crowned, the columnar body (3)

[0008]

Embodiments of the present invention will be described below. The drain plug device according to claim 1 will be described. The present invention relates to a drain plug device installed at a drain port opened at the bottom of a water tub such as a bathtub or a wash tub. Constituting this drainage device,
A drainage plug attached to the drainage port and an operation unit (12) for enabling remote control of opening and closing of the drainage plug via an operation wire (9);
The drain plug is provided with a cylindrical casing (8), a flange (11) provided around an upper edge of the casing (8), a valve element (1) seated on the flange (11), and the casing (8). Wings (1) extending in the centripetal direction from the inner peripheral surface of
0), which is connected to an end of an operation wire (9) extending from the operation section (12 ), and has a guide cylinder (7) for supporting the valve element (1). The casing (8) has a plurality of projections on the inner peripheral surface thereof.
And Katachi設the Okoshibutsu (8a), hair catcher (2) provided in said casing (8), the hair catcher (2)
A cylindrical body (3), a plurality of fins (4) radially protruding from the outer peripheral surface of the cylindrical body (3), and a tip of the fin (4) are covered to cover the inner periphery of the casing (8). And an arc-shaped band (5) along the surface. The columnar body (3) covers the guide cylinder (7) from above and houses the valve shaft (1a) supporting the main body (1) so as to engage with the lower end of the valve shaft (1a). A hook (3a) is formed at the upper end. The hair catcher (2) passes through a projection (8a) protruding from the inner peripheral surface of the casing (8) and passes through the wing (1).
0) A plurality of slits (6) for installation on the upper surface are provided. A drain plug device wherein the hair catcher (2) having the above structure is provided in the casing (8).

The present invention is configured as described above, and when it is used, in a casing (8) screwed into a drain opening formed in the bottom of the water tank, the hair is placed in a state where the valve element (1) is not installed. The catcher (2) is covered with the guide tube (7).
The guide tube (7) is supported by a mounting wing (10) extending in the centripetal direction from the inner peripheral surface of the casing (8), and an operation wire (10) extending from an operation portion (12) at an end thereof. 9)
Is connected to one end. In addition, upon this crown,
A band (5) is disposed at a position where the projection (8a) fits into the slit (6) so that the projection (8a) protruding from the inner peripheral surface of the casing (8) passes therethrough. The hair catcher (2) is dropped in the casing (8) until the body (3) abuts on the upper end surface of the guide tube (7). When the hair catcher (2) abuts, the locking projection (5a) formed on the band (5) is formed. ), The band (5) is rotated until the projection (8a) is locked. After being crowned in this manner, the valve body (1) is inserted from above into the guide cylinder (7) over the hook (3a) formed at the upper end of the columnar body (3).

[0010]

The present invention has the following excellent effects from the above configuration.

(1) When a strong operating force is transmitted from the operating portion to the valve body via a wire, the lower end of the valve shaft supporting the valve body and the hair are provided even if the valve body is urged to move up normally. Since the catch portion is a catch portion and engages with a hook formed at the upper end of the columnar body accommodating the valve shaft, there is no possibility that the valve body will be pulled out.

(2) Further, according to the present invention, a plurality of locking projections formed on the upper edge of the belt, which is the body of the hair catcher, and the projections projecting from the inner periphery of the casing engage with each other. Since the hair catcher is fixed in the casing, it does not move and does not generate rattling noise. In addition, since this engagement is released by rotating the hair catcher, the engagement is also removable.
