Integrated latch/hold-open system for Nefco launder covers
A system is provided for covering a launder channel of a clarifier tank, the launder channel having a tank wall and launder channel wall. The system comprises a mounting section connected to the launder channel wall, a hinge, and an openable cover panel, movable between a closed and open position. The mounting section includes an angled resting structure for supporting the cover panel, when in the open position, away from the mounting section.
1. A system for covering a launder channel of a clarifier tank, the launder channel having a tank wall and launder channel wall, said system comprising:
a mounting section connected to said launder channel wall;
a hinge;
an openable cover panel, movable between a closed and open position;
wherein said mounting section includes an angled resting structure, said angled resting structure for supporting said cover panel, when in the open position, away from said mounting section.
2. The system as claimed in claim 1 , wherein said angled resting structure has a locking post configured to be passed through a receiving hole to support said cover panel in said open position.
3. The system as claimed in claim 2 , wherein said locking post has a transverse locking pin.
4. The system as claimed in claim 1 , wherein said angled resting structure has a spring-loaded locking post configured to be passed through a receiving hole to support said cover panel in said open position.
5. The system as claimed in claim 4 , wherein said spring loaded locking post, has a rotatable handle connected by a pin to a shaft and, in turn to a spring, said shaft passing through a barrel, such that said handle can be either in a linear arrangement with said barrel in an open position, and where said handle can be rotated perpendicular to said barrel in a locked position.
6. The system as claimed in claim 1 , wherein said angled resting structure is disposed at an angle away from said mounting section.
7. The system as claimed in claim 6 , wherein said resting structure is angled at 30 degrees from said mounting section.
8. The system as claimed in claim 6 wherein said resting structure is angled to support said cover panel such that it supports said cover panel at the point when said hinge is unfolded to approximately 90°.
9. The system as claimed in claim 6 wherein said resting structure is angled to support said cover panel such that it supports said cover panel at a position that would contact said cover panel when the center of gravity just allows said cover panel to fall towards said mounting section.
10. A system for covering a launder channel of a clarifier tank, the launder channel having a tank wall and launder channel wall, said system comprising:
a mounting section connected to said launder channel wall;
a hinge;
an openable cover panel, movable between a closed and open position;
wherein said mounting section includes a locking post configured to be passed through a receiving hole to support said cover panel in said open position.
11. The system as claimed in claim 10 , wherein said locking post a spring-loaded locking post configured to be passed through a receiving hole to support said cover panel in said open position.
12. The system as claimed in claim 11 , wherein said spring loaded locking post, has a rotatable handle connected by a pin to a shaft and, in turn to a spring, said shaft passing through a barrel, such that said handle can be either in a linear arrangement with said barrel in an open position, and where said handle can be rotated perpendicular to said barrel in a locked position.
13. The system as claimed in claim 10 , wherein said mounting section includes an angled resting structure on which said locking post is mounted, said angled resting structure for supporting said over panel, when in the open position, away from said mounting section.
14. The system as claimed in claim 13 , wherein said angled resting structure is disposed at an angle away from said mounting section.
