Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drain cap for a balcony waterproof pan, which is fitted into a drain hole of the balcony waterproof pan.

[0002]

[Prior art]

 Conventionally, as a drain cap for balcony waterproof pans of this type, a screw-in type in which the inner and outer cylinders, which are engraved with threads to be screwed into each other on the joint surface, can be fixed by screwing them from above and below A drop-down type in which a cylinder made of a heavy material such as a casting is dropped into a drain hole was generally used.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned balcony waterproof pan drain cap has problems that the drain is likely to be clogged with dirt and the like due to the cylindrical body being inserted into the drain hole, and that the cap must be removed and installed easily during cleaning. .

The present invention was devised to solve the above-mentioned drawbacks of the conventional products, and has a drain cap for a balcony waterproof pan, which has less clogging and can be easily removed and installed during cleaning or inspection. Is intended to be provided.

[0005]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and is a dome-shaped drain body in which a plurality of operation windows are opened at a predetermined interval on a peripheral wall surface and a plurality of drainage openings are formed on the periphery of a lower opening. And a fixing metal fitting formed by bending an elastic band in a substantially inverted V shape and projecting locking pieces bent with the respective tip ends outward. A drain cap for a balcony waterproof pan, characterized in that the top of the fixing bracket is fixed to the back surface of the top of the drain body so that the stop piece projects downward from the lower opening.

As the locking piece of the fixing metal fitting in the present invention, one having a structure in which each tip of the fixing metal fitting is bent in a semicircular shape outwardly is preferable from the detachability of the cap. .

In addition, as the operation window of the drain body in the present invention, the operation window is used to have a size such that the fixing fitting can be operated with a fingertip, and is formed so as not to damage the fingertip during the operation. Has been done.

[0008]

[Action]

 The balcony waterproof pan drain cap according to the present invention has a dome-shaped drain body in which a plurality of operation windows are opened at a predetermined interval on the peripheral wall surface and a plurality of drain ports are opened at the periphery of the lower opening. And a fixing metal member formed by bending a band having elastic force into a substantially inverted V shape and projecting a locking piece bent with each tip end outward. Since the apex of the fixing bracket is fixed to the back surface of the top of the drain body so that the locking piece protrudes downward from the lower opening, the fixing bracket uses the elastic force of the fixing bracket. It is attached by sliding the locking piece on the inner wall surface of the drainage hole and locking the locking piece in the lower opening of the drainage hole, while inserting the fingertip into the operation window to attach the fixing bracket. Remove the knob locking piece from the lower opening of the drainage hole and pull it up. It can be removed by.

【Example】

 1 is a perspective view showing an embodiment of a balcony waterproof pan drain cap according to the present invention, and FIG. 2 is a sectional view of the same. Is.

In the figure, A is a drain body formed by pressing a metal plate into a dome shape having a truncated cone shape, and a plurality of drain bodies each having a size such that a fingertip can be inserted into a peripheral wall surface at a predetermined interval. The operation window 1 is opened, and a plurality of drainage ports 2 are opened on the periphery of the lower opening.

In the figure, B is a fixing member formed by bending a metal strip having elastic force, such as a stainless steel plate having a thickness of about 0.4 to 0.8 mm, into a substantially inverted V shape. A locking piece 3 which is bent outward in a semi-circular shape is projectingly provided at each tip.

The drain main body A and the fixing metal fitting B are spotted at the top of the fixing metal fitting on the back surface of the top of the drain main body so that the locking piece 3 projects downward from the lower opening of the drain main body A. It is attached by fixing it by welding.

FIG. 3 is a cross-sectional view showing another embodiment of the drain cap for the balcony waterproof pan according to the present invention, in which the drain body A is formed in a hemispherical dome shape, while the fixed body is fixed. The locking piece 3 of the metal fitting B is formed by bending it obliquely upward.

The drain cap for the balcony waterproof pan according to the present invention has the above-mentioned structure. Therefore, when using, as shown in FIG. 4, the elastic force of the fixing bracket B is used to remove the fixing bracket B from the drain hole C. It is fitted by sliding on the inner wall surface and the locking piece 3 is locked by the lower opening of the drainage hole C. On the other hand, a fingertip is inserted into the operation window 1 to fix the fixing bracket B. The stopper 3 is removed by removing it from the lower opening of the drainage hole C and pulling it up.

[0015]

[Effect of device]

 As is clear from the above, the drain cap for the balcony waterproof pan according to the present invention has a plurality of operation windows at predetermined intervals on the peripheral wall and a plurality of drain holes at the periphery of the lower opening. It consists of a dome-shaped drain body and a fixing bracket made by bending an elastic band in a substantially inverted V shape and projecting a locking piece that is bent with its tip end facing outward. , The apex of the fixing bracket is fixed to the back of the top of the drain body so that the locking piece projects downward from the lower opening, so the elastic force of the fixing bracket is used. It is attached by sliding the locking piece onto the inner wall surface of the drainage hole and locking the locking piece to the lower opening of the drainage hole, while inserting the fingertip into the operation window to secure the fixing bracket. By picking up and removing the locking piece and pulling up Cleaning and inspection in order to be able Rihazusu is simple, and as seen in conventional products, less clogging by sand or the like to the cylindrical body of the drain to the drainage hole is not fitted.
