Description

Drain cap {DRAIN CAP}

The present invention relates to a drain cap installed in the drain hole. In more detail, the present invention relates to a drain cap that can be smoothly drained by preventing foreign matter from entering the drain hole and can be easily installed in the drain hole.

Drainage pipes are installed on the roofs of buildings, roofs, basements, etc. to discharge rainwater and sewage used by people out of buildings. A drainage hole is formed in the cross section of the drain pipe so that rainwater and sewage may escape. However, when rainwater or sewage flowed through the drainage holes into the drainage pipes, it was often the case that various foreign matters came together into the drainage pipes and the drainage holes were blocked. In order to prevent this, a drain cap is conventionally installed in a drain hole formed in a roof of a building or the like, a roof, a basement floor, or the like.

The conventional drain cap is provided in a plate with a simple hole, so that the drain cap can be separated from the drain hole even by a small impact where the drain cap is installed, and when the drain cap made of light plastic is locked due to a large amount of drainage, the drain cap is also drained by buoyancy of water. There is a problem to break out of the hole. Therefore, it is difficult to make a light plastic material, and in order to install a conventional drain cap in the drain hole, a groove in which the drain cap can be seated is formed around the drain hole, or a screw is screwed along the exterior of the drain cap to drain the drain hole. The drain cap had to be secured to the drain hole using a circumference or adhesive such as silicone. Therefore, the cumbersome work of removing the adhesive and the screw, etc. when replacing the drain cap damaged by the impact or aged for a long time is followed.

Accordingly, one object of the present invention for solving the above-mentioned conventional problems is to provide a drain cap which can more stably fix the drain cap, and is easy to replace.

Another object of the present invention is to provide a drain cap that can prevent foreign matter from entering when water is drained into the drain hole.

Still another object of the present invention is to provide a drain cap which can prevent separation from the drain hole by an impact or the like.

The drain cap according to the present invention is provided to prevent foreign matter from entering the drainage hole formed on the roof of the building, the roof and the basement floor, and the like, and the filter unit having a hole through which water can be filtered out of a certain size and It includes an elastic piece that is coupled to the filter portion by a coupler such as a screw.

The filter unit may be disposed around the drainage hole formed to drain water from the rooftop or the like to cover the drainage hole, and the shape thereof may be variously manufactured, such as a flat plate, a hemisphere, or a cup. When the rainwater or sewage flows out into the drainage pipe, the filter can escape the water, but a plurality of holes are formed to filter the foreign matter that can enter the drainage hole and block the drainage pipe. In addition, the coupling portion may be formed in the central portion such that the coupling portion such as a screw can be coupled.

The elastic piece is bound to the filtering portion and the coupling portion using a coupling tool such as a screw, and may be provided in a thin plate shape using a synthetic polymer material such as metal or plastic having elasticity. One or more elastic pieces may be provided, and a coupling hole such as a screw may pass through the central portion and be bound to the coupling portion of the filter portion. Therefore, the elastic piece combined with the filtering portion is partially inserted into the drainage hole so that both end surfaces abut on both sides of the drainage hole. Made of thin metal plate or elastic material, it is joined to the filtration part and before opening into the drain hole, it is wider than the drain hole, and when inserted into the drain hole, it is bent and inserted into the drain hole. Therefore, both ends of the elastic piece are in close contact with the drainage hole by the force that the bent elastic piece returns to its original shape. Therefore, the filtration part is fixed to cover the hole of the drain hole, and the filter part is not easily separated or flows from the drain hole by an external force.

In addition, at least two elastic pieces may be provided, and one end of the elastic piece is bent toward the drain hole to be in close contact with the side surface of the drain hole. At the same time, the other end is engaged with the filtering portion formed by the coupling portion formed by the coupling portion such as a screw and the filtering portion. Therefore, the elastic piece combined with the filtering portion is partially inserted into the drainage hole so that one end thereof is in contact with one side of the drainage hole. For one, it is difficult to fix the filtration section, but two or more elastic pieces can be provided to fix the filtration section so as to cover the drainage hole, and the filtration section is prevented from leaving the drainage hole by a constant force.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

1 is an exploded perspective view of a drain cap according to the present invention. Referring to FIG. 1, the drain cap 100 includes a filtration unit 110 covering a drainage hole and an elastic piece 120 fixing the filtration unit 110 to the drainage hole.

The filter unit 110 may be disposed in a drain hole formed to drain water from a rooftop or the like to cover the drain hole, and the shape of the filter unit 110 may be formed in a hemispherical shape. In addition, the filter unit 110 may be formed when the rainwater or sewage is drained into the drainage pipe, but the water may escape, but a plurality of holes 115 are formed to filter the foreign matter that may be over a certain size to block the drainage pipe. The central portion is formed with a coupling portion that can be screwed.

Receiving grooves are formed in the bottom of the coupling portion to secure the elastic piece 120. The accommodating groove is formed in accordance with the appearance of the elastic piece 120 to be provided, and is provided in a cross or straight shape according to the number of the elastic pieces 120. In more detail, when one elastic piece 120 is provided, the shape of the receiving groove may be provided in a straight shape, and when two or more elastic pieces 120 are provided, they may be provided in a cross shape. However, since the purpose of providing the receiving groove is to prevent the elastic piece 120 from rotating, the shape may be modified by the manufacturer's intention.

In addition, the shape of the filter unit 110 may be manufactured in a plate such as square and round according to the intention of the manufacturer, in another embodiment according to the present invention can provide a filter unit of a different shape than the present embodiment.

The elastic piece 120 is bound to the filter part 110 and the coupling part using a coupling tool such as a screw 130, and is formed of a thin metal plate having elasticity. The elastic piece 120 is provided as a metal plate of one or more predetermined lengths, and a coupling hole such as a screw 130 passes through the center portion and may be coupled to the coupling portion of the filter portion. Therefore, the elastic piece 120 coupled to the filtration unit 110 is partially inserted into the drain hole so that both end surfaces abut on both sides of the drain hole.

It is made of a thin metal plate or a material having elasticity, and is coupled to the filtration unit 110 and is wider than the drainage hole before being inserted into the drainage hole and is bent and inserted into the drainage hole when inserted into the drainage hole. Both ends of the elastic piece 120 are in close contact with the inner surface of the drainage hole by the restoring force of the curved elastic piece 120. Therefore, the filter unit 110 is fixed to cover the hole of the drain hole, and the filter unit 110 does not flow by an external force.

2 is a cross-sectional view of the drain cap is installed according to the present invention.

Referring to FIG. 2, a drain cap 100 is provided on the bottom 150 on which the waterproof material 190 is laid. In general, since the drainage hole 160 formed in the floor 150 of the roof of the building is formed as a long hole having a narrow width, it is cumbersome to cover the waterproof material 190. Therefore, the waterproof hole 190 is generally not formed in the drain hole 160. However, if the waterproofing material 190 is not formed in the drainage hole 160, the phenomenon of lifting of the drainage hole 160 and the waterproofing material 190 may occur, and aging or leakage of the building through the drainage hole 160 may occur. In general, the plastic pipe 170 is provided in the drain hole 160 so that the water does not directly contact the drain hole 160 because it can proceed quickly. However, since the plastic pipe 170 is hard to bend, it cannot extend to a drain pipe (not shown) that drops water on the outer wall of the building. Therefore, the drain 180 is further provided to be easily bent to extend to the drain pipe. The drain 180 is placed inside the plastic tube 170 to the bent portion and is formed as a flexible tube. Thus, the plastic tube 170 can no longer be extended and can be easily bent at the broken end and extends to the drain pipe. In addition, the outer surface of the drain 180 is formed to be bent by giving a screw or a bend.

Referring back to FIG. 2, the drain cap 100 includes a filtration unit 110 that covers the drainage hole 160 and an elastic piece 120 that fixes the filtration unit 110 to the drainage hole 160. .

The filtration unit 110 may be disposed around the drainage hole 160 formed to drain water from a rooftop or the like to cover the drainage hole 160, and the shape of the filtration unit 110 may be manufactured in a hemispherical shape. In addition, the filter unit 110 may be formed when the rainwater or sewage is drained into the drainage pipe, but the water may escape, but a plurality of holes 115 are formed to filter the foreign matter that can enter the drainage hole and block the drainage pipe. In the center portion, a coupling portion to which the screw 130 is coupled is formed.

The filter unit 110 may also be manufactured in a plate such as square and round according to the intention of the manufacturer, and in another embodiment according to the present invention may provide a filter unit of a different shape from the present embodiment.

The elastic piece 120 is bound to the filter part 110 and the coupling part using a coupling tool such as a screw 130. The elastic piece 120 is provided as one long metal plate, and a coupling hole such as a screw 130 may pass through the center portion and be coupled to the coupling portion of the filtration unit 110. Therefore, the elastic piece 120 coupled to the filtration unit 110 is partially inserted into the drain hole 160 so that both end surfaces abut the inner side surfaces of the drain 180.

The elastic piece 120 is wider than the drainage hole 160 before being inserted into the drainage hole 160 so that when the elastic piece 120 is inserted into the drainage hole 160, the elastic piece 120 is bent and inserted into the drainage hole 160. Therefore, both ends of the elastic piece 120 are in close contact with the inner surface of the drain 180 by the restoring force of the curved elastic piece 120. Therefore, the filter unit 110 does not flow by the filter unit 110 by an external force.

In this embodiment, one elastic piece 120 is provided. Although only one elastic piece 120 may be used to fix the drain cap 100 to the drain hole 160, two or more elastic pieces 120 may be provided to provide the drain cap 160 with the drain cap 100. The fixing can be made more firm.

Example 2

3 is an exploded perspective view of the drain cap according to the second embodiment of the present invention.

Referring to FIG. 3, the drain cap 200 includes a filtration unit 210 that covers the drainage hole and an elastic piece 220 that fixes the filtration unit 210 to the drainage hole.

The filter unit 210 may be disposed around the drainage hole formed to drain water from the rooftop or the like to cover the drainage hole, and the shape of the filter unit 210 may be formed in a plate shape. In addition, a plurality of holes 215 are formed in the filtration unit 210. Rainwater or sewage may be discharged through the drain pipe through the hole 215, and the filter unit 210 may prevent foreign substances having a predetermined size or more from entering the drain hole by using the hole 215.

A central portion of the filtration unit 210 has a coupling portion to which the screw 230 is coupled. However, the filter unit 210 may be variously manufactured in a hemispherical shape and a circular plate according to the intention of the manufacturer. An accommodation groove is formed at the bottom of the coupling portion to fix the elastic piece 220. The receiving groove is formed to fit the appearance of the elastic piece 220, which is provided to prevent the elastic piece 220 from rotating.

The elastic piece 220 is bound to the filter part 210 and the coupling part using a coupling tool such as a screw 230, and is formed of a thin metal plate having elasticity. The elastic piece 220 may be provided as an elongated metal plate provided with at least two, and a coupling hole such as a screw 230 may pass through one end thereof and be coupled to the coupling part formed in the filtration unit 210. Therefore, the elastic piece 220 coupled with the filtering part 210 is partially inserted into the drain hole 260 so that the other end touches the inside of the drain hole. Since one filter piece 210 cannot be fixed to one elastic piece 220, two or more pieces should be provided. In this embodiment, three elastic pieces 220 are provided. Therefore, the drain cap 200 may be more firmly fixed to the drain hole than when one or two elastic pieces 220 are provided. In addition, more elastic pieces 220 may be provided to fix the drain cap 200 more firmly. The elastic piece 220 is provided in a plate shape, it can be bent and inserted when the drain cap 200 is installed in the drainage hole, but it is provided with a slight arc from the beginning in an arc shape having a constant radius to insert the elastic piece 220 in the drainage hole. Can be inserted with less force. Since the elastic piece 220 that is bent and inserted into the drain hole is intended to return to its original shape, one end of the elastic piece 220 is further in close contact with the inner surface of the drain hole by the force. Therefore, the filter unit 210 is fixed to cover the hole of the drainage hole, and the filter unit 210 does not flow by an external force.

4 is a cross-sectional view illustrating an example in which a drain cap according to a second embodiment of the present invention is installed. Referring to FIG. 4, a drain cap 200 is provided on a floor 250, such as a roof of a building. In general, foreign matter is introduced into the drainage hole 260 formed in the floor 250 of the roof of the building, and the drainage hole 260 may be blocked. Since the drain hole 260 is formed of a narrow and long hole, when the foreign matter enters, the drainage hole 260 may not only be easily blocked, but also difficult to remove the foreign matter. Therefore, in order to prevent such troublesome work, the drain cap 200 is installed to prevent foreign matter from entering the drain hole 260 in advance.

Therefore, by providing a drain cap according to the present invention it is possible to prevent the drainage hole is blocked by foreign matter when the sewage and rain water is drained through the drainage hole formed in the floor of the toilet, bathroom and roof of the building.

In addition, since the drain cap according to the present invention is fixed to the drain hole by using an elastic piece, it can be fixed regardless of the size of the drain hole, and does not require a separate facility for fixing the filter.

In addition, by providing a drain cap according to the present invention can be securely fixed to the drain hole without the use of an adhesive, it is also easy to replace.

As described above, the present invention has been described with reference to a preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
