[24] Especially for the unique featured body section ( 44 ), there is protruded leaf on the upper sides of the four outer side surfaces on a designated height and both sides of the four outer sides, there is mounting hole ( 21 ) and it has upper protruded leaf which can make even level with the top side of the body section ( 44 ) and there is bottom protruded leaf which is located beneath of the upper protruded leaf ( 22 ) with a certain gap ( 25 ) to the upper protruded leaf.

[25] Also, for the other two sides, it has a middle protruded leaf which have mounting holes ( 21 ) and have the same thickness as the upper and lower protruded leaves and same height and depth as the gap ( 25 ).

[26] That is for the both two sides of the four out side surfaces, there are upper and bottom protruded leaves ( 22 ) ( 26 ) and for the other two sides, there is middle protruded leaf ( 24 ) which is located between the upper protruded leaf ( 22 ) and bottom protruded leaf ( 26 ) in height so that when assembling the multiple number of these sub assembly ( 20 ) to protect offensive odor and vermin from the sewage, it can be assembled simply inserting each other by using the middle protruded leaf ( 24 ) and gaps ( 25 ) with out any need of the special part.

[27] Also, these sub assembly ( 20 ) to protect offensive odor and vermin from the sewage are composed with the rectangular shape for the upper assembling parts but the other inner rim of the body section ( 44 ) are composed with unique feature of round shape to make opening outlet of the running water smoothly and protect accumulation or suspension of the foreign material and sludge coming in with the running water in side of the device.

[28] FIG. 4 is a sectional view 'A-A' and detail view of the sub assembly ( 20 ) to protect offensive odor and vermin from the sewage, and in this drawing as shown, there is an elastic device ( 50 ) which control the opening and closing of the open and close door plate ( 46 ) located on the top of the outlet opening hole ( 42 ) in which the aforementioned open and close door plate ( 46 ) is installed on it. And for this design, this elastic device ( 50 ) is composed of a plate spring and assembled on to the body section ( 44 ) and make the opening and closing of the open and close door plate ( 46 ). And this elastic device ( 50 ) can be optionally made of the coil spring which will be wound to the hinge ( 48 ) and any kinds of elastic device which can surely make opening and closing of the open and close door plate ( 46 ) will satisfy these function.

[29] FIG. 5 shows the assembled condition of the multiple devices of the sub assembly (

20 ) to protect offensive odor and vermin from the sewage in series at the same direction to make a united body and it is assembled by inserting the middle protruded leaf ( 24 ) prepared at the each outside of the sub assembly to the gaps ( 25 ).

[30] As shown above, protection device for the offensive odor and vermin(lθ) that uses multiple devices of the sub assembly to become a united body and the number of the sub assembly to be used to be the completed protection device for the offensive odor and vermin(20) depending on the size of the drain and on the outer rim of protection device for the offensive odor and vermin( 10 ), it is a supporting plate( 60 ) to be hanged to the man hole of the sewage.

[31] On the supporting plate( 60 ) mentioned above, there are mounting holes( 62 ) on a same distance to be assembled to the mounting hole( 21 ) on the protruded leaf part of each sub assembly to protect offensive odor and vermin by the screw thread through each other. In case upper and bottom protruded leaf( 22 )( 26 ) are located on the most outer side, the mounting hole( 62 ) of supporting plate( 60 ) is first inserted into the gap( 25 ) and in case the middle protruded leaf( 24 ) is located on the most outer side, on the top side of this middle protruded leaf, the one side of the supporting plate where mounting hole is located will be laid down to the middle protruded leaf and is fixed with screw so as to be parallel with the surface of protection device for the offensive odor and vermin.

[32] Also, when such standardized sub assembly ( 20 ) to protect offensive odor and vermin from the sewage is assembled and installed, it will maintain close contact between each sub assembly to protect offensive odor and vermin from the sewage through inserting method between the middle protruded leaf and gap as shown on the some of the detail drawing of the FIG 5. As such aforementioned manner, through close sealing maintained between two assembled parts, the offensive odor & vermin generated from inside the sewage can be effectively prevented from coming out through but depending on the man hole cover for the sewage, there will be a difference in size between the most outer rim of protection device for the offensive odor and vermin and the size of inner part of the man hole cover for the sewage. To prevent offensive odor and vermin from coming out through such a difference in size between the outer rim of the protection device for the offensive odor and vermin and the inner part of the man hole cover for the sewage, adjustable supporting channel( 70 ) can be equipped additionally to adjust the gap between sub assembly to protect offensive odor and vermin from the sewage.

[33] The adjustable channel( 70 ) mentioned above, as shown in FIG 6, is located between each of the sub assembly to protect offensive odor and vermin, there will be plate which have different height for the inserting area ( 72 ) in both sides so that middle protruded leaf( 24 ) is inserted to the gap for the one side and upper and bottom protruded leaf( 22 )( 26 ) will be inserted to the gap to the other sides. And the assembled condition and detail view of the assembled condition is shown in FIG. 7.

[34] The adjustable channel( 70 ) mentioned above can be inserted between sub assembly ( 20 )to protect offensive odor and vermin from the sewage as explained above but it can also be used on the most outer side of the united sub assembly ( 20 ) to protect offensive odor and vermin from the sewage by attaching supporting plate( 60 ) to the out side of it.

[35] On the other hand from this point, explanation on the function and operation of this patented the protection device for the offensive odor and vermin( 10 ) which is composed as the above will be described by referencing FIG. 8 and 9.

[36] The number of the sub assembly to protect offensive odor and vermin from the sewage of the patented protection device for the offensive odor and vermin( 10 ) can be decided depending on the size of the sewage man hole, it can be applied to the various sizes of the sewage man hole.

[37] Also, the protection device for the offensive odor and vermin( 10 ) can be composed of multiple of sub assembly ( 20 ) to protect offensive odor and vermin from the sewage by tight fit each other using the gap ( 25 ) and upper and bottom protruded leaf ( 22 )( 26 ), it can be assembled easily and give the convenience of the installation with out the need of the special tool.

[38] Also, after putting a separate coffin-shaped supporting plate( 60 ) using fixing screw onto the rim part on the most outer side of the standardized sub assembly ( 20 )device to protect offensive odor and vermin from the sewage, the sub assembly ( 20 )device to protect offensive odor and vermin from the sewage that has the supporting plate( 60 ) assembled can be hanged on the inner part of the sewage man hole. After that ether by placing a separately equipped protection device for the inlet of foreign materials or just by placing the manhole cover ( 5 ) on it, the installation process will be completed. With such simple process, it will save working hours and labor cost.

[39] Also, as shown in FIG 9, should the running water from the outside reaches a certain point within the body section ( 44 ) where a protection device for the offensive odor and vermin( 10 ) is installed, open and close door plate( 46 ) equipped inside the body section ( 44 ) will fall back depending on the weight of the running water.

[40] When weight has been reduced on open and close door plate( 46 ) after the running water has been discharged, open and close door plate( 46 ) will close the outlet opening hole ( 42 ) promptly due to the elasticity of the elastic device( 50 ) and do not let any offensive odor or vermin created inside the sewage be emitted to the outside.

[41] Especially, because the inner rim of the sub assembly device to protect offensive odor and vermin from the sewage is a round shape, even if some foreign materials come in with the running water, it will not let suspend or accumulate on it effectively compare with the former square shaped device.

[42] Also, this patented sub assembly ( 20 ) to protect offensive odor and vermin from the sewage is assembled and installed in standardized size, there will be a differences in size between the most outer rim of protection device for the offensive odor and vermin and the size of the man hole cover for the sewage. To prevent offensive odor and vermin from coming out through such a difference in size between the outer rim of the protection device for the offensive odor and vermin and the size of the man hole cover for the sewage, adjustable supporting channel( 70 ) can be equipped additionally to adjust the gap between sub assembly to protect offensive odor and vermin from the sewage.

[43] As explained above, since this protection device for the offensive odor and vermin can be used just by simply assembling multiple sub assembly devices to prevent offensive odor and vermin, the installing is simple allowing reduction of cost and increase the efficiency. And should there be a small difference in size between the assembled sub-assembly devices to prevent offensive odor and vermin and the man hole, width adjusting device can be inserted between the most outer rim of the sub- assembly devices to protect offensive odor and vermin and the supporting channel ( 70 ), the gap will disappear and the odor and vermin can be effectively prevented from coming out from the sewage. And since the inner rim of the body section is round shaped, even if some foreign materials coming in with the running water, it won't remain inside nor disturb the discharge of the running water thus it is much more effective than the former square-shaped body section.
