It is an object of the present invention to solve such a problem and further provide a device in which a large number of ventilation ports 2 can be attached without any trouble. In addition, it also aims at a reliable dust removal effect. [Structure] Outer spring plates 3A that bend outwardly at positions facing each other are attached to the left and right parts of a cylindrical portion 2A of a publicly known plastic ventilation port 2, and a filter is attached to the upper surface of the galan in the ventilation port 2. It is set up.

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. Since the board 4 is mainly composed of gypsum, it is brittle and weak, and the fact that the ventilation port 2 peels off and falls over time frequently occurs. In addition, such work requires, for example, the trouble of applying the adhesive 2D on the upper surface of the flange, the labor of inserting the cylindrical portion 2A into the ventilation hole circular hole and raising it, and bonding the lower surface of the board 4 to the flange. It takes. It is common to install thousands of ventilation openings 2 in a single condominium, and it must be said that today's labor shortage is a serious problem.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, according to the present application, a cylindrical portion 2A configured to be loosely fitted to the ventilation hole circular hole 4A, and a flange portion 2B continuously connected to the lower end of the cylindrical portion in a horizontal state outward, An outer spring plate 3A that bends outward is attached to the cylindrical portion 2A of the ventilation port 2 that is composed of a galan portion 2C stretched in the opening at the lower end of the cylindrical portion, and It is a one-touch mounting type ventilation port with a filter 4 stretched on the upper surface.

In this case, upper and lower circular holes 2E and 2F opened at positions opposite to each other in the right and left parts of the cylindrical portion 2A, and a spring plate having a width that allows loose fitting in the circular holes 2E and 2F are used as materials. Consists of an outwardly curved outer spring plate 3A and an outwardly curved inner spring plate 3B located inside the outer spring plate. In addition, the upper end portion of the spring 3 can be inserted and locked in the upper circular hole 2E, and the lower end 3B1 of the inner spring plate 3B can be inserted and locked in the lower circular hole 2F.

In addition, the outer spring plate 33A is curved outward and the vertical inner spring plate 33B is located inside the outer spring plate 33B. The spring 33 connected by the portion 33C can be configured such that the inner spring plate 33B and the connecting portion 33C are positioned and fixed inside the cylindrical portion 2A when forming the ventilation port 2.

【Example】

 Examples will be described with reference to the drawings. 1 is a one-touch mounting type ventilation opening of the present invention. Reference numeral 2 denotes a publicly known ventilation hole made of plastic, which is continuously connected to a lower end of the cylindrical portion 2A which is configured to be loosely fitted to the ventilation hole circular hole 4A and is horizontally oriented to the lower end of the cylindrical portion. It is composed of a flange portion 2B and a galan portion 2C stretched over the opening at the lower end of the cylindrical portion. Reference numerals 2E and 2F denote upper and lower circular holes which are formed in the left and right portions of the cylindrical portion 2A so as to face each other. The diameter of these circular holes 2E and 2F is about 5 mm.

Reference numeral 3 denotes a spring, which is made of a spring plate having a width such that it can be loosely fitted in the circular holes 2E and 2F, and has an outer spring plate 3A that acts outwardly and an inner spring plate of the outer spring plate. And an inwardly curved inner spring plate 3B positioned outward, which are connected at the upper end. When the spring 3 is attached to the ventilation port 2, the upper end of the spring 3 is inserted and locked in the upper circular hole 2E, and the lower end 3B1 of the inner spring plate 3B is fixed in the lower circular hole 2F. Insert and lock. As a result, the outer spring plates 3A are attached to the right and left portions of the cylindrical portion 2A in an outwardly enlarged state. Reference numeral 5 is a known filter that is detachably stretched on the upper surface of the galan portion 2C.

Reference numeral 11 denotes a one-touch attachment type ventilation port of another embodiment. 2A is a cylindrical portion of a publicly known ventilation hole 2 made of plastic, and this cylindrical portion is sized so that it can be loosely fitted in the ventilation hole circular hole 4A. It is composed of a flange portion 2B that is continuously provided and a gallan portion 2C that is stretched over the opening at the lower end of the cylindrical portion.

Reference numeral 33 denotes a spring, which is made of a spring plate having a width of about 5 mm. The outer spring plate 33 A bends outward, and the vertical inner plate located inside the outer spring plate 33 A. The spring plate 33B and the spring plate 33B are connected at the upper end by a downwardly U-shaped connecting portion 33C. The spring 33 is attached to the cylindrical portion 2A by fixing the inner spring plate 33B and the connecting portion 33C in the cylindrical portion 2A when forming the ventilation port 2. As a result, the outer spring plates 33A are attached to the right and left portions of the cylindrical portion 2A in an outwardly enlarged state. Reference numeral 51 is a publicly known filter which is stretched on the upper surface of the galan portion 2C. As the filters 5 and 51, for example, a Travelon air filter (trademark-Kanai Important Industry Co., Ltd.) was suitable.

The operation will be described together with the effect.

[0013]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. 1. Construction is possible in a short time simply by opening the ventilation hole circular hole (for example, a diameter of 100 m / m) and mounting it on the board 4. 2. You can easily deal with different board thicknesses. 3. Since the filter 5 is stretched on the upper surface of the galan portion 2C, a reliable dust removing effect can be exerted.
