Description

[Detailed explanation of the invention] A. Purpose of the invention a. Industrial application field This invention relates to the improvement of drainage fittings, such as so-called perforated plates installed on bathroom floors, and other floor surfaces that can be cleaned by flushing water. It is widely related to drainage fittings, such as the so-called cleaning opening provided in.

b. Prior Art In conventional drainage fittings of this type, the disk-shaped mounting plates, such as the strainer part of the perforated plate and the lid part of the cleaning port, are either simply fitted into the frame or are screw-in type. Things are common. There is also a device that has an inverted bowl-shaped member made of synthetic resin attached to the back of the mounting plate, and uses its elasticity to lock into the frame.

C. Problems to be solved by the invention Among the conventional drainage fittings mentioned above, those in which the disk-shaped mounting plate such as the strainer part or the lid part is simply fitted into the frame body do not have the problem that something gets caught. In such cases, the strainer may come off carelessly, and the strainer, lid, etc. may be lost. On the other hand, the screw-in type does not come off accidentally and will not be lost, but it takes time and effort to attach and remove it. In addition, the above problem is solved by attaching and detaching the mounting plate with an inverted bowl-shaped member made of synthetic resin from the frame, but it cannot be used for perforated plates with drainage holes in the mounting plate. However, there is a problem in that material costs, manufacturing costs, etc. are relatively high due to the structure.

The present invention is an attempt to solve the above-mentioned problems of conventional drainage fittings. In other words, the purpose is to make it possible to attach and detach the disk-shaped mounting plates of the strainer and lid parts to and from the frame with a single touch, to prevent them from being accidentally removed or lost, and to be manufactured at low cost. Our objective is to provide drainage fittings that are suitable for

B. Structure of the invention a. Means for solving the problems The drainage fitting according to the invention includes a frame 2 fixed to a floor surface 1, and a disc-shaped mounting plate 3 placed on the upper part of the frame 2.
The frame body 2 has a tapered circumferential surface 5 formed near the top of the inner circumference of the short cylindrical part 4, and the short cylindrical part 6 formed at the bottom of the mounting plate 3 is made of an elastic material. An annular body 7 is fixed to the sleeve, an annular groove 8 is formed on one of the tapered circumferential surface 5 and the annular body 7, and a locking protrusion 9 that can be engaged with the groove 8 is formed on the other side. The mounting plate 3 can be attached to and detached from the frame body 2.

In the above configuration, the material of the ring body 7 is a material that has at least some elasticity, such as hard rubber or soft polypropylene. In the illustrated embodiment, the annular groove 8 is formed on the tapered peripheral surface 5.
Further, although the locking projections 9 are provided on the ring body 7, the locking projections 9 are not limited thereto, and each may be provided in the opposite manner. The locking convex portion 9 is preferably annular, but may be partial. Note that Figures 1 to 4 show the case of a perforated plate, and Figure 5 shows the case of a cleaning opening, but the difference is that the mounting plate 3 is a strainer part with holes in the former, and a lid part without holes in the latter. Other than that, almost everything else is the same.

In the figure, 10 is a seat for supporting the plate, 11
is a notch for removing the mounting plate;
It is formed on a part of the inner circumference.

b. Function This drainage fitting is used in the same way as before, installed on the floor 1 in a place where water is handled. In this drainage fitting, when the mounting plate 3 is placed on the frame 2, the locking protrusion 9 on the other side is engaged with the annular groove 8 on one side, so the mounting plate 3 is Even if something hits you, it won't come off carelessly. Moreover, the mounting plate 3 will not be lost because of this.

Next, when removing the mounting plate 3 as necessary, for example, when cleaning a clogged drain pipe with a perforated plate, or when draining water from a cleaning opening,
What is necessary is to insert something into the plate removal notch 11 and pry up the plate 3. In this case, since the ring body 7 is made of an elastic material, the concave groove 8 and the convex portion 9, both of which are elastic, can be easily separated, and the mounting plate 3 can be removed with a single touch.

Furthermore, when the removed mounting plate 3 is to be fitted into the frame 2, it is sufficient to simply push the lower part of the mounting plate 3 into the upper part of the frame 2. As a result, one of the locking protrusions 9 is engaged with and locked with the annular groove 8, but in this case, since the ring body 7 is made of an elastic material, the protrusion 9 and the groove 8 are easily engaged. Then, the mounting plate 3 is locked with one touch.

C. Effects of the Invention As is clear from the above, the drainage fitting according to the present invention, unlike conventional drain fittings, allows disk-shaped mounting plates such as the strainer section and the lid section to be attached to and detached from the frame body with a single touch. Furthermore, once the mounting plate is attached, it will not come off carelessly and will not be lost. Moreover, it can be used as a perforated plate having a strainer section with drainage holes, and since the structure is simple, it has useful effects such as reducing manufacturing costs.

Regarding the cleaning opening as shown in Figure 5,
By using a ring made of elastic material,
Since it is in close contact with the inner circumferential surface of the frame, it is possible to prevent odor from rising from below. As shown in FIG. 6, even if a ball 14 is provided on one side between the frame body 2 and the mounting plate 3 to protrude with a spring 13, and a recess 15 for ball engagement is formed on the other side, it can be attached and detached with one touch. This also makes it possible to prevent the mounting plate 3 from coming off or being lost inadvertently.

Claims (1)

[Scope of utility model claims] It consists of a frame body 2 fixed to a floor surface 1 and a disk-shaped mounting plate 3 placed on the upper part thereof, and a tapered circumferential surface 5 is formed on the frame body 2 toward the upper part of the inner circumference of the short cylindrical part 4. death,
A ring body 7 made of an elastic material is fixed to a short cylindrical part 6 formed at the lower part of the mounting plate 3, and an annular groove 8 is formed in either the tapered circumferential surface 5 or the ring body 7. This drainage fitting has a locking convex portion 9 that can be engaged with the groove 8 on the other side, thereby making it possible to attach and detach the mounting plate 3 to and from the frame body 2.
