Description

  The present invention relates to a drain lid, and more particularly to a drain lid that is used by being attached to a drain outlet of a drain pipe such as a veranda or a rooftop.

  Conventionally, as this kind of drainage lid, the lid body covering the drainage port can be separated according to the size of the drainage port so that the outer diameter can be adjusted according to the size of the drainage port There are some in which concentric grooves are formed (for example, see Patent Document 1).

By the way, conventionally, the drain outlet provided in the veranda etc. of the building has a case where it is formed in an upper surface opening shape on the floor surface, and a case where it is formed in the lower portion of the side wall in an opening shape on the side.
In the latter case, the lower edge of the drain outlet is usually positioned at the same height as the floor surface. Therefore, the drain lid attached to this type of drain outlet has a lower part of the drain lid as shown in FIG. It is customarily formed in a straight line so that it can come into contact with the floor surface and be attached stably.
Therefore, conventionally, there are two types of drainage lids of this type, one for floors and one for side walls where drainage ports open sideways.
Therefore, in the past, for example, two types of molds are required, and space is required for storage, and if it is not a type that fits the direction of the drain port, installation work can not be done, resulting in poor workability and ease of use. There was a problem.
Thus, the conventional product described in Patent Document 1 adjusts the size of the lid body in accordance with the size of the drain outlet. Therefore, depending on this, it was impossible to attach the lid main body portion to the floor surface in close contact with the floor surface.
Japanese Patent Laid-Open No. 2001-311198

The present invention has been proposed in view of such conventional problems.
Therefore, the technical problem to be solved by the present invention is that the direction of the drainage port is not restricted, and the drainage port can be handled in one type even when it is in the horizontal direction. An object of the present invention is to provide an easy-to-use drainage lid formed so as to be easy, quick and reliable.

The present invention employs the following technical means in order to solve the above problems.
That is, the present invention extends from the center position of the back surface of the synthetic resin cover body 2 covering the drain port 1a of the drain pipe 1 and the back surface of the drain body 1 to the back side direction as shown in FIG. A drainage lid that is formed with a drainage flow hole 2a in the lid body 2 and is attached by being inserted into the drainage port 1a. A thin-walled portion 6 for cutting out a part of the lid main body portion 2 to form a size covering the laterally facing drain port 1a on the back surface of the main body portion 2 connects two points on the outer periphery of the lid main body portion 2. It is formed on L (Claim 1).

  Here, the size of the laterally facing drainage port 1a is defined such that the remaining lid body 2 that has been cut off has a leg portion 3 that is inserted into the laterally facing drainage port 1a and is larger than the diameter of the drainage port 1a. It means that it has been. The thin-walled portion 6 is formed on a straight line L connecting two points on the outer periphery of the lid main body 2. The cut portion is formed in a straight line, and the lower portion of the lid main body 2 is the floor surface. 7 is formed so as to come into contact with 7 in a stable posture. As the thin portion 6, for example, there is one formed in a cross-sectional groove shape or a V-shape. As shown in FIG. 1 and the like, the thin-walled portion 6 is formed in a lattice shape with vertical and horizontal bars 2b, and when the gap between the bars 2b is formed in the drainage flow hole 2a, the bar 2b Alternatively, it is formed on the back surface of the outer peripheral frame 2c to which the crosspiece 2b is attached. Further, when the drainage circulation hole 2 a is not formed on the upper surface of the lid main body 2 but is formed on the peripheral side surface of the lid main body 2, the thin-walled portion 6 is a straight line continuous with the back surface of the lid main body 2. Alternatively, it is formed in a dotted line shape.

Thus, in the case of the present invention, the above-mentioned leg portion 3 has a plate surface up and down on one shaft 3a extending from the center position of the back surface of the lid main body portion 2 in the back side direction and the open end of the shaft 3a. It is formed with a flexible strip 3b that is mounted laterally toward the direction and symmetrically about the shaft 3a, and is reinforced with a plate 3a sandwiched between the central plate surface of the strip 3b. The ribs 4 are formed in a parallel pair, and both sides of the band plate 3b ahead of the portion where the ribs 4 are formed are bent into a U shape and inserted into the drainage port 1a, and the restoring force of the band plate 3b It is preferable that it is formed in close contact with the inner wall of the drain port 1a.
This not only simplifies the attachment work to the drain pipe 1, but also allows the rib 4 to reinforce the central portion of the strip 3b and increase the restoring force on both sides of the strip 3b. This is because it can be made of a material to reduce costs and weight.

In the case of the present invention as set forth in claim 2, as shown in FIGS. 2 and 5, etc., the pull-out prevention that engages with the step portion 1b of the inner wall of the drain pipe 1 at both ends of the upper surface of the strip 3b. It is preferable that the nail | claw 5 for use is formed (Claim 3).
This is because according to this, it is possible to easily and reliably prevent the drainage port 1a from coming off or dropping off.

In the present invention, on the back surface of the lid main body portion covering the drain outlet of the drain pipe in this way, a thin wall portion for cutting out a part of the lid main body portion to form a size covering the laterally oriented drain outlet is provided on the lid main body. It is formed on a straight line connecting two points on the outer periphery of the part.
Therefore, in the case of the present invention, even if the drain outlet is in the horizontal direction, it can be handled by one type, and since only one type of mold is required, the manufacturing cost can be reduced and the product can be provided at a low cost. In addition, the present invention can cope with by cutting a part of the lid main body part from the thin wall portion in accordance with the direction of the drain outlet in the field. According to this, the covering operation of the drain outlet can be facilitated and speeded up. It can be reliably constructed without any restrictions on the direction.

Hereinafter, the best mode for carrying out the present invention will be described.
As shown in FIG. 1 and the like, the present invention extends from the center position of the back surface of the synthetic resin cover body 2 covering the drain port 1a of the drain pipe 1 and the back surface of the cover body portion 2 in the rear side direction. A drainage circulation hole 2a is formed in the lid main body part 2, and the leg part 3 is formed so as to be inserted into the drainage port 1a.

  The lid body 2 is formed in a quadrangular shape with four corners chamfered in plan view. Further, the lid main body 2 has strip-like crosspieces 2b formed in a lattice form vertically and horizontally, and an opening between the crosspieces 2b is formed in the drainage circulation hole 2a. The crosspiece 2b and the outer peripheral frame 2c forming the outer periphery are integrally formed of a synthetic resin material such as polypropylene.

  As shown in FIG. 2 and the like, the leg portion 3 has a plate surface on one shaft 3a extending from the center position of the back surface of the lid main body portion 2 in the back side direction and an open tip of the shaft 3a. It is formed of a flexible strip 3b that is mounted horizontally and symmetrically about the shaft 3a in the vertical direction. The leg portion 3 is formed of a synthetic resin material such as polypropylene together with the lid main body portion 2, the lid main body portion 2 and the shaft 3a are integrally formed, and the shaft 3a and the band plate 3b are connected by post-processing. .

  Reference numeral 4 denotes a reinforcing rib. The ribs 4 are integrally formed in a pair of parallel shapes on both sides of the plate surface with the shaft 3a interposed between the rib 3 and the upper plate surface in this embodiment in the center of the band plate 3b. The product of the present invention is bent into a U-shape on both sides of the strip 3b ahead of the portion where the rib 4 is formed and inserted into the drain port 1a, and is closely attached to the inner wall of the drain port 1a by the restoring force of the strip plate 3b. It is what is done.

  Further, in the product of the present invention according to this embodiment, the removal-preventing claw 5 that engages with the step portion 1b (see FIG. 5) of the inner wall of the drain pipe 1 is formed at both ends of the upper surface of the strip 3b. Yes. In this embodiment, the stepped portion 1b is formed at a connecting portion that is generated when the drainage pipes 1 are fitted together. In the product of the present invention, the claw 5 is engaged with the stepped portion 1b on the inner wall of the drain pipe 1 to prevent the claw 5 from being detached from the drain port 1a or falling off.

  6 (refer FIG. 1B) is a thin part for cutting out a part of lid main-body part 2 and forming it in the magnitude | size which covers the horizontal-shaped drain outlet 1a. The thin-walled portion 6 is formed on the back surface of the lid main body portion 2 on a straight line L connecting two points on the outer periphery of the lid main body portion 2, and in this embodiment, on the back surfaces of the crosspiece 2 b and the outer peripheral frame 2 c. Is formed.

Next, a usage example of the present invention will be described.
First, as shown in FIGS. 1A, 5 and 6, when the drain port 1a is formed on the floor surface 7 of a veranda or the like so as to face upward, the operator must touch both sides of the strip 3b with fingers. The belt plate 3b is bent into a U-shape and inserted into the drain port 1a. In this case, both end portions of the strip 3 b are inserted deeper than the step portion 1 b of the drain pipe 1.

  When the finger is released from the band plate 3b, the band plate 3b is restored in the drain pipe 1, and both end portions spread outward to press the inner wall of the drain pipe 1. Therefore, according to the present invention, both ends of the band plate 3b press the inner wall of the drain pipe 1 and are attached to the drain port 1a. Further, in this case, in this embodiment, the claw 5 is engaged with the step portion 1b, so that the removal is surely prevented.

Next, as shown in FIGS. 7 to 10, a case will be described in which the drain port 1 a is laterally opened at the lower portion of the side wall 8 such as a veranda.
In this case, using the thin part 6 formed in the lid body 2, the operator first cuts off a part of the lid body 2 and covers the lateral drainage port 1a. 2 is formed. This separation operation is performed by putting fingers or a cutter or a cutter into the thin portion 6. Next, the operator attaches a straight cut-off portion of the lid main body 2 to the floor surface 7, and inserts and attaches the leg 3 to the drain outlet 1a by the same operation as in the above example. In the present invention, since a part of the lid main body 2 is formed so as to be linearly cut in this way, even if the drain port 1a is in the horizontal direction, it can be handled in one type.
