Safety sign hanging fixture for manhole}

The present invention relates to a safety sign latch fixture for a manhole that allows the safety sign to be detachably fixed inside the manhole using a bracket, thereby preventing safety accidents and injury to the safety sign due to backflow during heavy rain. will be.

The structure of a conventional manhole consists of a manhole frame buried in the ground and a manhole cover mounted on and coupled to a stopper of the manhole frame.

However, since the manhole cover is a structure that is simply placed and connected to the manhole frame, there is no risk factor in normal times, but when there is a flood due to heavy rain, rainwater may flow back from the sewer. At this time, the manhole cover is opened by the water pressure pushed from the bottom of the manhole cover, allowing water to flow. There are times when you are pushed out of place.

In this case, since the surrounding area is usually submerged in water, the manhole hole is not visible to pedestrians, and therefore, cases of drowning by falling into the manhole frequently occur.

Of course, conventional manhole covers also have some exhaust holes and drainage holes, but these are of little significance for rainwater flowing back during floods.

Accordingly, a device is being developed to prevent pedestrians from falling even when the manhole cover is opened by installing a safety sign on the ledge formed on the inner periphery of the manhole. However, the basic structure is to simply place a safety sign on the seating ledge of the manhole. In this case, there was a problem that during heavy rain, safety signs were injured by backflow of sewage and did not help prevent falling accidents.

Accordingly, in developing safety signs, in addition to newly manufactured manholes that can be used for the developed safety signs, there is a need to develop a device that allows the safety signs to be used on the seating ridges of existing manholes. am.

On the upper surface of the extension part 44, a plurality of fixing pieces 48 corresponding to and fitted into the plurality of fastening holes 46 are formed on the bottom surface, and are fastened with a cross-sectional shape of '┍┑', and the stopping bar ( 20) a fixing part (47) that allows it to be fitted inside; It consists of,

The lower bracket 50, which has a fitting groove 51 into which the fitting protrusion 45 is inserted, is fastened to the bottom of the upper bracket 40 to form one body.

That is, the difference between the first and the second is that the part where the stopping bar 20 is inserted is formed in the vertical part 42 of the upper bracket 40 itself and the case where a separate extension part 44 is provided. It becomes.

In the case of the lower bracket 50, the present invention has two embodiments.

The lower bracket 50 is designed to be selectively used in the first and second forms depending on the thickness of the seating protrusion 110 into which the latch portion 30 is fitted.

The first form is a horizontal plate in which a fitting groove 51 into which the fitting protrusion 45 is inserted is formed on one side, and the other side extends to face the horizontal portion 41 of the upper bracket 40, that is, a straight shape. It has the shape of a horizontal plate.

In the second form, a fitting groove 51 into which the fitting protrusion 45 is inserted is formed on one side, and a bent portion 52 bent downward in an 'ㄴ' shape is formed on the other side, so that the upper, The locking space A of the lower brackets 40 and 50 is formed to be relatively larger and has the same shape that faces and opposes the shape of the upper bracket 40 described above. In other words, the upper bracket 40 and the lower bracket 50 are spaced apart from each other upward and downward and are horizontal, forming an 11-shaped figure.

When in use, the lower bracket 50 is arranged in a horizontal position with the upper bracket 40 to form a locking space A in the shape of a 'ㄷ' cross-section on one side of the latch portion 30, and when not in use, the lower bracket 50 is placed in a horizontal position with the upper bracket 40. (When the latch part 30 is not used in the form of being clamped to the seating jaw 110, or when the latch part 30 is removed from the seating jaw 110, etc.), it forms a right angle to the upper bracket 40. By rotating it to either the left or the right, the upper bracket 40 and the lower bracket 50 are spaced apart from each other so that they are not horizontal. As a result, the upper bracket 40 is placed on the upper surface of the seating jaw 110, but the lower bracket 50 does not contact the bottom of the seating jaw 110, so the latch portion 30 that is engaged with the seating jaw 110 ) so that it can be removed by lifting it to the top.
