[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a drain port lid around water in a kitchen or the like, and is suitable for applications in which it is also required to work as part of the floor surface.

[0002]

[Prior art]

 This type of lid, which is also used as a part of the floor surface, is made of, for example, a casting, but since the surface has unevenness peculiar to the casting, it is difficult to wash off dirt etc. The problem is that it is unacceptable in terms of rust and aesthetics. On the other hand, stainless steel, which has been adopted in many kitchens in recent years, has a smooth surface, has no sanitary problems, is resistant to rust, and is aesthetically suitable for kitchens.

By the way, since the conventional stainless steel lid is plate-shaped, the plate portion between the water passages is structurally weak, and since it is used as a part of the floor surface, it is heavy. It is likely that it will be dented and deformed under the load of. Although this problem can be solved by increasing the plate thickness, a large press facility is required, and a new sanitary problem occurs due to the rough cross section of the water inlet. It may be possible to cut the material, but this requires a lot of work and is economically problematic. On the other hand, even if it is made of the same stainless steel, there is no concern about the structural strength described above in the case of the double girder structure, but there is a problem that it is heavy and difficult to handle even for cleaning.

[0004]

[Problems to be solved by the device]

 The problem to be solved is to provide a moldable workability, a plate portion strength between water passage portions, a shear surface of the water passage portion, slip prevention of the plate portion, weight, and an economical structure that does not have any problems. .

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, a plurality of elongated hole-shaped water passages are provided in a horizontal plate portion of a metal lid main body from one side edge of a plate portion on the long side of the water passage port. It is characterized in that it is formed in the stamped-out trace of the drooping part that hangs down in the same body, and that a reinforcing rib composed of the drooping part is disposed at one side edge on the long side of the water passage opening.

Further, in the present invention, a non-slip convex portion is stamped and formed on the surface of the plate portion, and at the same time, the peripheral edge of the plate portion is hung from the peripheral edge and is integrally continuous with each other. It is characterized in that side portions are provided.

Further, the present invention is characterized in that the lid body is made of a stainless plate member.

The planar shape of the lid body in the present invention may be a quadrilateral shape, an elliptical shape, a circular shape, or any other suitable shape similar to these. Further, the water passages in the plate portion may be arranged in parallel, in a radial shape, or in any other suitable array shape. The material of the lid body may be a known metal member that is appropriately plated.

[0009]

[Action]

 A plurality of elongated hole-shaped water inlets are formed on the horizontal plate portion of the metal lid main body in the ejection trace of the hanging portion that hangs down from the one side edge of the plate portion on the long side of the water inlet in the same body. Since the reinforcing rib consisting of the above-mentioned sloping portion is arranged at one side edge on the long side of the water inlet, the water passage and the sloping portion can be press-molded at one time, which is excellent in workability and economy. . The strength of the plate portion between the water passage portions is strengthened by the reinforcing ribs made of the sloping portion and is strong, and does not cause deformation such as denting even under the load of heavy objects, and the floor surface It can be used as a part. Furthermore, since the strength of the plate between the water inlets is strengthened by the reinforcing ribs, the plate thickness of the plate itself can be made so that the shear cross section of the water inlet does not become rough, and the shear cross section of the water inlet is smooth. It is easy to wash off dirt and eliminates hygienic problems. It is structurally lightweight and easy to handle for cleaning.

Further, a non-slip convex portion is stamped and formed on the surface of the plate portion, and side portions that are hung from the peripheral side edge of the plate portion and that are integrally continuous with each other are disposed on the peripheral side edge of the plate portion. Therefore, it is safe not to slip when walking on the board, and the whole board is reinforced by the side parts and is robust.

Further, since the lid body is made of a stainless plate member, it is resistant to rust and is aesthetically suitable for a kitchen or the like.

【Example】

 1 to 3 illustrate an embodiment of a drainage port lid according to the present invention, in which a lid body 1 made of a stainless steel plate member is provided with a plurality of long hole-shaped passages on each side of a horizontal plate portion 2. The water holes 8 are formed in parallel. Each of the water passages 8 is formed on the punched-out trace of the hanging portion 9 that hangs down from the one side edge of the plate portion 2a on the long side of the water passage, and the long side of each water passage 8 is formed. Reinforcing ribs 10 composed of the hanging portions 9 are arranged on one side edge, respectively. The corner portion 8a on the punching side of the water passage port 8 is rounded so that the drooping portion 9 can be easily punched out. Further, an appropriate number of non-slip projections 11 are stamped and formed on the surface of each plate portion 2a so as not to slip on the plate portion 2 when walking.

The lid body 1 has front and rear side portions 4 and 4 which are almost double the height of the reinforcing ribs 10 by folding down the front and rear side edges, and has the same height on the left side edge. The left side portion 5 is arranged by welding the right side portion 6 having the same height on the right side edge, and the front and rear side portions 3, 4 adjacent to each other and the ear portion 5a and the right side portion 6 of the left side portion 5 are arranged. The side portions 3, 4, 5 and 6 are integrally continuous with each other by spot welding with the ear portion 6a. Further, on the back side of the plate portion 2b which separates the left and right water passages 8 in the lid body 1, the middle side portion 7 having the same height as the side portions 3, 4, 5, 6 is arranged, and the ear portion thereof is provided. 7a is spot welded to the central portions of the front and rear side portions 3 and 4 which are adjacent to each other.

[0014]

[Effect of the Invention] A. According to the first aspect, the water passage and the drooping portion can be press-molded at one time, which is excellent in workability and economy. Further, the strength of the plate portion between the respective water passage portions is strengthened by the reinforcing rib formed of the above-mentioned hanging portion, and is strong, so that deformation such as denting does not occur even under the load of heavy objects. Furthermore, since the plate strength between each water inlet is strengthened by the reinforcing ribs, the thickness of the plate itself can be made so that the shear surface of the water inlet does not become rough, and the shear cross section of the water inlet is smooth. It is easy to wash off dirt and eliminates hygienic problems. In addition, it is structurally lightweight and easy to handle for cleaning.

B. According to the present invention, the anti-slip projections are stamped and formed on the surface of the plate portion, and at the same time, the peripheral side edges of the plate section are hung from the peripheral side edges and are integrally continuous with each other. Therefore, it is safe not to slip when walking on the plate part, and the whole plate part is reinforced by the side part and is robust.

C. According to claim 3, since the lid body is made of a stainless plate member, it is resistant to rust and is aesthetically suitable for a kitchen or the like.
