Abstract

PROBLEM TO BE SOLVED: To prevent a rotation in the case of the opening and closing of a cock cover by constituting a drain cock device so as to control the rotation in the horizontal plane of the shaft of the cock cover, and to prevent the pulling of a release by the revolution and the deterioration of cutoff performance as seen in conventional devices. SOLUTION: A cock cover 5 is constituted in an openable and closeable manner in the vertical direction through a release 6, and the shaft 51 of the cock cover 5 is slid and contacted to the inner circumference of a guide section 41 for an attachment 4 fixed onto a drain-inlet metal fitting 2 and moved vertically. A projecting section 51a is formed to the outer circumference of the shaft 51 of the cock cover 5, a recessed section 41a is formed to the inner circumference of the guide section 41, and a rotation in a horizontal plane in the case of the opening and closing of the cock cover 5 is controlled by an engagement between the projecting section 51a and the recessed section 41a at that time.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing the arrangement of a drain plug device. A drain port H is formed on a bottom surface 1b of the bathtub 1 and a drain metal fitting 2 is fixed to the drain port H by tightening a nut 3. An attachment 4 is mounted in the drain fitting 2, and a guide portion 4 of the attachment 4 is provided.
1, the stopper 51 is configured so that the shaft 51 of the stopper 5 can be opened and closed by sliding in the vertical direction, and the stopper 5 is connected to the operation unit 7 via the release 6. The operation unit 7 is provided so that it can be attached and fixed to a fixture 8 previously fixed to the side wall surface 1a of the bathtub. Each time the push button 7a of the operation unit 7 is turned on, the operation unit 7 is released. The stopper lid 5 is opened and closed via the opening 6.

In FIG. 2, a stopper 5 and an attachment 4
A detailed description will be given below with reference to an exploded perspective view of the drain fitting 2. The drain fitting 2 has a male screw 2 b formed on an outer periphery of a main body cylindrical portion 2 a, and an outer end is provided at an upper end of the main body cylindrical portion 2 a. And a flange portion 2c is formed integrally with the main body so as to protrude horizontally.
Further, a lower inner flange 2d is formed integrally with the lower end of the main body cylindrical portion 2a so as to protrude horizontally inward, and a fitting notch 2e is formed at a predetermined interval in the lower inner flange 2d. It has become.

The attachment 4 is made of resin. A cylindrical guide portion 41 is provided at the center in a rising shape, and a cylindrical outer peripheral fitting portion 42 is disposed outside. The outer peripheral fitting portion 42 and the guide portion 41 are connected and integrated by a plurality of connecting ribs 43, and the outer peripheral fitting portion 42 is provided with fitting pieces 42a,
42a are formed, and a locking claw 42b protruding outward is formed at the lower end of each fitting piece 42a. In this attachment 4, the outer peripheral fitting portion 42 is inserted from above into the inner periphery of the main body tubular portion 2a of the drainage fitting 2, and the fitting piece 42a fits into the fitting notch 2e.
The locking claw 42b is configured to be engaged with the lower end of the main body cylindrical portion 2a, and to be fixed to the drainage fitting 2 in a state in which removal is prevented.

The outer peripheral fitting portion 42 of the attachment 4
A plurality of hooks 4 projecting inward on the inner peripheral side
The hooks 44, 44, 44 play a role of hooking and removing hair and dust in the drain water flowing down the drain hole H. Guide part 4 of attachment 4 in this example
A concave portion 41a is formed in the inner periphery of the vertical portion 1 so as to be vertically concave. On the other hand, the outer periphery of the shaft 51 which is integrally hung from the center of the bottom surface of the stopper 5 protrudes outward in the vertical direction and has a convex portion 5.
1a is formed, and the convex portion 51a is
Is formed so as to fit into the concave portion 41a.

FIG. 3 is a plan view showing a state in which the shaft 51 of the stopper 5 is inserted into the guide 41. Since the protrusion 51a of the shaft 51 fits into the recess 41a of the guide portion 41 in this manner, the rotation of the shaft 51 in the horizontal plane is restricted, and therefore, the stopper 5 rotates in the horizontal plane. When the stopper 51 is opened and closed in the up and down direction by the operation of the operation section 7 and the shaft 51 slides in the up and down direction on the inner periphery of the guide section 41, the protrusion from the recess 41a is 51a
Is not pulled out, the rotation of the stopper 5 in the horizontal plane can be prevented well, and the release 6 can be prevented from being bent. The stopper 5 is securely closed on the upper surface of the drainage fitting 2 in a cover-like manner, so that the water stopping performance is ensured.

FIG. 4 shows a second embodiment. In the plan view of FIG.
1, a plurality of recesses 41a, 41a, 4 at predetermined intervals.
1a and 41a are formed. On the other hand, one protrusion 51a is formed on the shaft 51 so as to protrude, and the protrusion 5a of the shaft 51 is inserted into any of the recesses 41a, 41a and 41a.
1a is configured to fit. With such a configuration, when the nut 3 is fixed to the bottom surface 1b of the bathtub 1 by tightening the nut 3, there is no need to determine the fixing position of the drain metal fitting 2, and the drain metal fitting 2 can be tightened in any direction. Even if it is fixed, the convex portion 51a of the shaft 51 of the stopper 5 is inserted into any one of the recesses 41a of the guide portion 41 of the attachment 4 attached to the drainage fitting 2 to rotate the stopper 5 in a horizontal plane. This makes it possible to install the release 6 in a position where no bending occurs, and it is not necessary to determine the fixing position of the drainage fitting 2. There is no need to keep the orientation constant.

Next, FIG. 5 shows a third embodiment. In FIG. 5, a convex portion 41b is formed on the inner periphery of the guide portion 41 of the attachment 4 so as to protrude inward.
A concave portion 51b is formed in a concave shape on the outer periphery of the shaft 51, and the convex portion 41 of the guide portion 41 is formed in the concave portion 51b.
b, the rotation in the horizontal plane when the shaft 51 of the stopper 5 moves up and down is regulated by the convex portion 41b and the concave portion 51b. In addition, since the hook part 44 is integrally formed in advance on the attachment 4, there is no need to install another hair catcher,
Since the number of parts is reduced and the number of parts is small, construction can be easily performed.

[0011]

According to the present invention, a stopper for covering a drain port on the bottom of a bathtub can be opened and closed in an up-down direction by operating an operating part connected via a release, and a shaft vertically attached to the stopper. In a drain plug device having a structure that slides up and down on the inner periphery of a cylindrical guide portion provided at the drain port, the concave and convex portions engage with the outer periphery of the shaft of the stopper lid and the inner periphery of the guide portion. By providing a portion, and configured to regulate the rotation of the shaft in the horizontal plane, there is no rotation when opening and closing the stopper, the release is pulled as in the conventional, the release is pulled, the water stopping performance is reduced There is no such thing.

Further, since a plurality of concave portions or convex portions are formed at equal intervals on the inner circumference of the guide portion, it is not necessary to make the direction of the drainage fitting fixed to the drainage hole constant, so that the construction can be performed. It will be easy.

The guide part is formed on an attachment part detachably attached to a drain port of the bathtub, and the attachment part has a catch part for preventing passage of hair, dust and the like during drainage. With the provision, there is no need to separately install a hair catcher, the number of parts can be reduced, the cost can be reduced, and the construction can be easily performed.
