Abstract

A swimming pool debris trap having an externally operable venting mechanism for reducing pressure or vacuum in the trap.

Claims

1. A swimming pool debris trap having an externally actuatable venting mechanism for reducing pressure or vacuum in the trap, further comprising a lid and a canister, the lid carrying the venting mechanism, the venting mechanism being spring-biased into a vent-closed position.

2. A swimming pool debris trap as having an externally actuatable venting mechanism for reducing pressure or vacuum in the trap, further comprising a lid and a canister, the lid carrying the venting mechanism, the venting mechanism having a venting handle for actuating the venting mechanism, the lid having a lid handle, the venting handle being parallel to the lid handle.

3. A trap as claimed in claim 2, the venting handle being beneath the lid handle.

4. A swimming pool debris trap having an externally actuatable venting mechanism for reducing pressure or vacuum in the trap, the venting mechanism comprising a shaft extending through a wall of the trap, a spring biasing the shaft into a vent-closed position, whereby external actuation of the shaft against the spring can move the shaft into a vent-open position.

5. A trap as claimed in claim 4, the venting mechanism further comprising a plug, a pan on an end of the shaft, and a washer in the pan, the plug having a circular ridge, the washer bearing against the circular ridge in the vent-closed position.

6. A trap as claimed in claim 5, the plug having a port, the washer being free of the ridge and above the port in the vent-open position, whereby the trap can vent through the port in the vent-open position.

7. A swimming pool debris trap having an externally actuatable venting mechanism for reducing pressure or vacuum in the trap, further comprising a lid and a canister, the lid carrying the venting mechanism, the venting mechanism comprising a shaft extending through the lid, a spring biasing the shaft into a vent-closed position, whereby external actuation of the shaft against the spring can move the shaft into a vent-open position.

8. A trap as claimed in claim 7, the venting mechanism further comprising a plug, a pan on an end of the shaft, and a washer in the pan, the plug having a circular ridge, the washer bearing against the circular ridge in the vent-closed position.

9. A trap as claimed in claim 8, the lid having a tube extending radially outwards on the lid, the plug having a port opening into said tube, the washer being free of the ridge and above the port in the vent-open position, whereby the trap can vent through the port into the tube to atmosphere in the vent-open position.

10. A swimming pool debris trap having an externally actuatable venting mechanism for reducing pressure or vacuum in the trap, further comprising a lid and a canister, the lid carrying the venting mechanism, the canister having a boss, the lid having lugs clamping the boss for holding the lid to the canister in a trap-closed state, contacting surfaces of the lugs with the boss in the trap-closed state being horizontal.
