In the figure, reference numeral 1 denotes a pan according to the present invention, which is placed on a pan receiver D formed at the upper edge of the opening of a drain trap B attached to the drain of the waterproof pan A (see FIG. 4). It is what is done. The eye plate 1 is made of a flexible elastic body (for example, EVA (ethylene vinyl acetate copolymer) resin).

  The plate main body 11 having a circular shape in plan view has a diameter larger than the opening diameter of the drain trap B by a predetermined dimension so that the entire opening of the drain trap B can be covered. In the case of the illustrated example, the eye plate main body 11 has a dish-like shape that is formed of a gently curved surface that is convex upward when viewed from the side, but may be a flat dish. .

  An elbow insertion hole 12 for inserting a hose connection elbow C rising from the drain trap B is formed at the center of the eye plate main body 11. In addition, a plurality of leg portions 13 having a predetermined height are provided at substantially equal intervals in the circumferential direction on the lower surface of the main dish body 11 at positions facing the counter dish D formed on the upper edge of the opening of the drain trap B. (Eight in the illustrated example) are provided so as to project the plurality of leg portions 13 on the eye plate receiver D so that the whole of the eye plate main body portion 11 is raised by the height of the leg portion 13. The water passage gap 19 (see FIG. 4) for collecting leaked water is formed between the eye plate main body 11 and the waterproof pan A.

  The eye plate main body 11 is formed with a first cut portion 14 that extends from the outer periphery to the elbow insertion hole 12 and reaches from the outer periphery to the elbow insertion hole 12. Furthermore, the hole edge part of the elbow insertion hole 12 located on the opposite side to the first notch part 14 is provided with a cross-shaped notch 15a at the tip part along the extension line of the first notch part 14. The second cut portion 15 is formed to the vicinity of the outer peripheral edge of the eye plate main body portion 11, and is configured so that the eye plate main body portion 11 can be expanded by expanding to the left and right by the first and second cut portions 14 and 15. Yes.

  Further, at the outer position of the cross-shaped cut 15a at the tip of the second cut 15, there is a hinge property when the eyepiece main body 11 is expanded left and right along the first and second cuts 14 and 15. In order to improve, a gap 16 having a U-shape in plan view is formed so as to surround the tip of the cross-shaped cut 15a. Further, an inverted U-shaped knob 17 that also serves as a reinforcement of the hinge portion 18 is located on the extended line of the first and second cut portions 14 and 15 and projects integrally with the outer side of the gap portion 16. ing.

  In the case of the eye plate of the present invention, the surface of the eye plate main body part 11 is not formed with any water holes formed in the conventional eye plate. The surface is smooth and smooth with no water holes.

The eye plate of the present invention having the above structure is used as follows.
First, the attachment of the eye plate 1 to the opening of the drain trap B is performed as follows. That is, the left and right ends of the first cut portion 14 are held, and the eyepiece main body 11 is pushed open in the left-right direction. Thereby, as shown in FIG. 5, the eye plate main-body part 11 is expanded right and left by using the hinge part 18 as a rotation fulcrum.

  In this expanded state, the expanded portion is pressed against the hose connecting elbow C rising from the drain trap B, and the whole eye plate 1 is pushed toward the hose connecting elbow C side. As a result, the hose connection elbow C is fitted into the hose insertion hole 12 of the eye plate 1, and the insertion of the hose connection elbow C into the elbow insertion hole 12 is completed.

  When the insertion of the elbow C for hose connection is completed as described above, the eye plate 1 is pushed downward and the leg portion 13 erected on the lower surface of the eye plate main body 11 is placed above the opening of the drain trap B. It is placed on the pan support D formed on the edge. Thereby, as shown in FIG. 4, the eye plate 1 is mounted on the eye plate receiver D in a state where the eye plate main body portion 11 is lifted upward by the height of the leg portion 13. As a result, a water passage gap 19 is formed between the eye plate main body 11 and the waterproof pan A for allowing the leaked water spilled onto the waterproof pan A to flow into the drain trap C.

  On the other hand, in order to remove the eye plate 1 during cleaning or the like, the inverted U-shaped knob 17 may be grasped and the entire eye plate 1 may be pulled toward the front side. When the whole of the eye plate 1 is pulled toward the front side, the eye plate main body 11 expands to the left and right with the first and second cut portions 14 and 15 as a boundary, and the eye plate 1 is connected to the elbow for hose connection. Can be easily removed from C.

  When the eye plate 1 is attached and detached, the eye plate main body 11 is greatly pushed right and left with the first and second cut portions 14 and 15 as a boundary, so that the eye plate main body 11 divided into right and left is connected. A large force acts on the portion of the hinge portion 18 that is present, and there is a risk that the eyepiece main body 11 may be cut or damaged at this portion for a long time. Therefore, in the present invention, the inverted U-shaped knob 17 is also provided integrally with the hinge portion 18 so as to serve as a knob for attaching and detaching the eye plate, thereby reinforcing the hinge portion 18.

  In the case of the eye plate of the present invention, the surface of the eye plate main body 11 is not provided with any water passage holes used in the conventional eye plate, but from the washing machine or water faucet on the waterproof pan A. When water is spilled down, the spilled leaked water is guided into the drainage trap B through the water passage gap 19 formed between the eye plate main body 11 and the waterproof pan A, and into the waterproof pan A. There is no accumulation.

  In addition, in the case of a conventional eye plate, it is likely to become quite dirty when hair, lint, dust, etc. get caught in a water passage hole formed on the surface of the eye plate. On the other hand, in the case of the eye plate of the present invention, the surface portion of the eye plate main body 11 is not drilled with any water passage holes for allowing leakage water to pass, and the surface is smooth and smooth. ing. For this reason, hair, lint, dust and the like are not entangled or caught on the surface of the main body 11 of the eye plate, and the surface of the eye plate which tends to become dirty can always be maintained in a beautiful state.

  In addition, the cross-shaped cut 15a is formed at the tip of the second cut 15 and the tip of the cross-shaped cut 15a is surrounded by a space 16 that is U-shaped in plan view. The horizontally expanding operation of the main plate main body 11 along the notches 14 and 15 becomes smooth, and the eye plate can be attached and detached more easily.

  Further, since the inverted U-shaped knob 17 is erected integrally with the hinge portion 18 between the second cut portion 15 and the outer peripheral edge of the eyepiece main body 11, the knob is attached when the eyeglass is attached or detached. 17 can be securely attached and detached, and the knob 17 can reinforce the portion of the hinge portion 18 that is easily subjected to excessive force when the eyepiece main body 11 is expanded in the left-right direction. The life of the eye plate can be extended.

  In the above-described embodiment, the entire eye plate 1 is made of an elastic body. However, the entire eye plate is not necessarily made of an elastic body, and at least the eye plate main body 11 is made of an elastic body. The leg portion 13 may be made of hard plastic or the like, and the leg portion 13 made of hard plastic may be bonded and fixed to the lower surface portion of the eye plate main body 11.
