Description

[Detailed Description of the Invention] This invention relates to a drain plug used to close the drain of a washbowl, a sink tank, a bathtub, etc.

Conventionally, drain plugs shown in FIGS. 8 to 10 are known.

In the one shown in FIG. 8, the upper end of a hook shaft 52 protruding toward the upper surface of the axis of the drain plug body 51 protrudes upward from the washbowl bottom surface 53, and a hook 54 is attached to the protruding portion. Although it is easy to put a finger on the sink 54, if another bowl, etc. 55 is placed on the washbowl bottom surface 53, the hook shaft 52 will get in the way, making it impossible to place the bowl, etc. 55 horizontally.

In the one shown in FIG. 9, the upper end of the hook shaft 57 that protrudes toward the upper surface of the axis of the drain plug body 56 does not protrude upward from the washbowl bottom surface 58, so that other Although it is possible to place a bowl or the like horizontally, since the hook 59 is located inside the drain port 60, it is difficult to put your finger on the hook 59, especially if the drain port 60 has a small diameter.

In the one shown in FIG. 10, a knob 62 protruding toward the upper surface of the axis of the drain plug main body 61 is located inside the drain port 63 and does not protrude from the bottom surface 64 of the washbowl. In order to make it easier to pick up the knob 62 with your fingertips, the diameter of the knob 62 must be increased, but if the diameter of the knob 62 is increased, there is no room for inserting your fingers outside of the knob 62.
I can't pinch 2. If the diameter of the knob 62 is made smaller to make it easier to insert a finger, the knob 62 becomes difficult to grip and the fingers tend to slip, making it impossible to remove the drain plug.

This invention solves the above problem, washbasin,
To provide a drain plug having a hook whose hook shaft does not protrude from the bottom of a sink water tank, bathtub, etc. and which can be easily hung with a finger.

The basic structure of this invention is that in a drain plug where the hook is attached to the hook shaft of the drain plug body so that it can be raised up and down, the hook is attached to the engaging shaft of the hook that is lying on its side. It is provided with a protruding portion that protrudes toward the target. To remove the drain plug from the drain of a washbowl, sink aquarium, bathtub, etc. that uses this drain plug, place your fingertip on the protruding part of the hook that is lying on its side and push it. It rotates approximately 90 degrees using the center of rotation, and stands upright, protruding from the drain. Therefore, the drain plug can be easily removed by hooking a finger on the hook in the upright position and pulling it up. Hereinafter, embodiments of this invention will be described based on the drawings.

First Embodiment In FIGS. 1 to 3, a drain plug 1 consists of a drain plug main body (hereinafter referred to as main body) 2 and a hook 3, and the outer peripheral surface of the main body 2 fits into a drain port 4. The tapered shape has a hook shaft 5 at the center of the shaft.
is inserted and fixed. The upper end of the hook shaft 5 projects toward the upper surface of the main body 2 by a predetermined length. Its length is such that when the drain plug 1 is fitted into the drain port 4, the upper end of the hook shaft 5 does not protrude upward from the bottom surface 6 of the washbowl or the like. An engagement hole 7 is formed through the upper peripheral surface of the hook shaft 5.

On the other hand, the hook 3 supported by the hook shaft 5 has an engaging shaft 9 directed inwardly at both ends of a roughly semicircular finger rest 8, and the middle part of the engaging shaft is in a state where the hook 3 is in a sideways position ( In FIG. 2), a curved protrusion 10 is formed so as to protrude upward from the main body 2. This protrusion 10 is set at a height such that it does not protrude upward from the bottom surface 6 of the washbasin or the like.

The drain plug 1 is shown in FIG. 2 in a state in which the drain port 4 is closed, and the hook 3 is in a horizontal position.
When the protrusion 10 is pressed with a finger in this state, the hook 3 is rotated approximately 90 degrees about the engagement shaft 9, and the hook 3 is placed in an upright position as shown in FIG. By being in the upright state, the finger hook part 8 interposed within the drain port 4 largely protrudes to the outside of the drain port 4, making it easier for a finger to hang onto the finger hook part 8.

Second Embodiment In FIGS. 4 to 6, a drain plug 11 has a drain plug main body (hereinafter referred to as main body) 12 and a hook 1.
3, the outer peripheral surface of the main body 12 is tapered to fit into the drain port 14, a recess 15 is provided on the upper surface side, and a hook shaft 16 is inserted and fixed to the shaft center. In the main body 12 of this embodiment, the drain port 1
The area that is in close contact with the inner peripheral surface of the main body 2 of the first embodiment is
becomes larger than The upper end of the hook shaft 16 is projected so as to be interposed in the recess 15, and is configured not to project upward from the bottom surface 17 of the washbowl or the like. An engagement hole 18 is provided through the upper peripheral surface of the hook shaft 16.

On the other hand, the hook 13 supported by the hook shaft 16
In this example, an engaging shaft 20 is provided inwardly at both ends of a finger hook 19 having a substantially semicircular shape, and the middle part of the engaging shaft 20 is located at the center of the main body 12 when the hook 13 is in a sideways state (FIG. 5). Projection part 2 curved to project upward
1 is formed. This protrusion 21 is set at a height such that it does not protrude upward from the bottom surface 17 of the washbasin or the like.

The state in which the drain port 14 is closed with the drain plug 11 is shown in FIG. 5, with the hook 13 lying on its side. In order to raise the hook 13, it is sufficient to place a finger on the protrusion 19 and press it, as in the first embodiment.

Note that the protrusions 10 and 21 in the above-mentioned embodiments were formed by curving the engagement shafts 9 and 20, but as shown in FIG. The hook 25 may be provided with a shaped engagement shaft 23 and a protrusion 24 fixed to the engagement shaft 23.

Since this invention has the above configuration, it has the following advantages.

Even if the drain plug has a small diameter and is lying on its side, and it is difficult to raise it by placing your finger on the finger hook of the hook, you can rotate the hook to the upright position by placing your finger on the protrusion provided on the hook and pushing. Since the finger hook portion of the shiso protrudes above the drain port, it becomes easy to hang the finger on the finger hook portion.
