Abstract

Systems, devices, apparatus, and methods of locking and unlocking a door that is slidable by articulating wheels in tracks, over an entry port to a storm water structure. Locking the door can be accomplished by rotating bolts that are attached to cams. Rotating the bolts causes the cams to press the door against the tracks. Sealing strips can be compressed between door edges and the track to prevent water from passing around the door. A vacuum truck can remove water and debris from the vault/structure. Other versions allow doors to move downward to allow water to overflow the door. The door can slide upward so water can flow underneath. A door in door version has a secondary door slide up and down in tracks in a main door.

Claims (49)

1. A damper system for storm water treatment structures, comprising:

a frame attached to wall of a vault structure with an opening therethrough;

tracks attached to the frame about the opening;

a door having wheels, the wheels slidably received within the tracks, the door having an open position for allowing water to flow into the vault structure and a closed position for preventing water from passing into the vault structure;

at least one vertical member rotatably mounted by at least one mount only to the door adjacent to a side of the door and

moveable members along one side face of the door for pushing the door against portions of the track, the moveable members including an upper moveable member mounted adjacent to an upper corner of the door and a lower moveable mounted adjacent to a lower corner of the door.

2. The damper system of claim 1 , wherein the moveable members include:

rotatable cams along outer side edges of the door, the cams having an unlocked position where the door is loosely seated in the tracks and a locked position where the door is pushed against one side of the tracks, wherein the locked position prevents water from passing about the edges of the door.

3. The damper system of claim 2 , further comprising:

a tool for rotating the cams from the unlocked to the locked position.

4. The damper system of claim 3 , wherein the removable tool includes:

a socket wrench for rotating the cams from the unlocked to the locked position.

5. The damper system of claim 1 , further comprising:

elongated seal member between the perimeter of side edges of the door and one side of the tracks, wherein the moveable members in a locked position cause the door to compress the elongated seal member against the one side of the tracks so that water is sealed and prevented from entering about the side edges of the door.

6. The damper system of claim 1 , further comprising:

a handle attached to the door.

7. The damper system of claim 6 , further comprising:

an elongated tool having an end portion adapted to be attached and detached to the handle.

8. The damper system of claim 7 , wherein the elongated tool includes:

a hook end for attaching to the handle, wherein lifting the handle raises the door from the tracks, and allows the storm water to enter into the vault structure.

9. The damper system of claim 1 , further comprising:

articulating members for allowing the wheels to bend at an angle to allow the door to be removed with reduced friction.

10. The damper system of claim 1 , wherein the moveable members include:

a single elongated rotatable cam on each lateral side edge of the door.

11. A damper system for storm water treatment vault structures, comprising:

a frame attached to a wall of a vault structure, with an opening therethrough;

tracks attached to the frame about the opening;

a slidable door having edges being slidable within the tracks, the slidable door having one position for allowing water to flow over the door into the vault structure and another position for allowing the water to flow under the door into the vault structure, and a closed position for preventing the water from flowing into the vault structure; and

a member for raising and lowering and closing the slidable door

at least one elongated member rotatably mounted by a mount only to the door adjacent to a side of the door;

spaced apart moveable members each mounted to extend horizontal and perpendicular to the at least one elongated member, wherein rotating the vertical elongated member rotates the moveable members in a horizontal axis from a loose position where the door is loosely seated in the tracks to the closed position where the door is pushed against one side of the tracks by the moveable members.

12. The damper system of claim 11 , wherein the moveable members include:

rotatable cams along the outer side edges of the door, the cams having an unlocked position where the door is loosely seated in the tracks and a locked position where the door is pushed against one side of the tracks, wherein the locked position prevents water from passing about edges of the door.

13. The damper system of claim 12 , further comprising:

a tool for rotating the cams from the unlocked to the locked position.

14. The damper system of claim 13 , wherein the removable tool includes:

a socket wrench for rotating the cams from the unlocked to the locked position.

15. The damper system of claim 11 , further comprising:

elongated seal member between the perimeter of the side edges of the door and the one side of the tracks, wherein the moveable members in a locked position causes the door to compress the elongated seal member against the one side of the tracks so that water is sealed and prevented from entering about the edges of the door.

16. The damper system of claim 11 , further comprising:

a handle attached to the door.

17. The damper system of claim 16 , further comprising:

an elongated tool having an end portion adapted to be attached and detached to the handle.

18. The damper system of claim 7 , wherein the elongated tool includes:

a hook end for attaching to the handle, wherein lifting the handle raises the door from the tracks, and allows the storm water to enter into the vault structure.

19. The damper system of claim 11 , further comprising:

articulating members for allowing the wheels to bend at an angle to allow the door to be removed with reduced friction.

20. The damper system of claim 11 , wherein the moveable members include:

a single elongated rotatable cam on each lateral side edge of the door.
