Abstract
An air plunger is described. The air plunger comprises an upper barrel and a lower barrel slidably received by the upper barrel. An air seal is fixed to the lower barrel and slidably engages with the upper barrel. A nozzle is attached to the lower barrel opposite to the upper barrel. A stop mechanism prohibits the upper barrel from disassociating with the lower barrel.
Claims19
An air plunger comprising:
- an upper barrel;
- a lower barrel slidably received by said upper barrel;
- an air seal fixed to said lower barrel and slidably engaged with said upper barrel;
- a nozzle attached to said lower barrel opposite to said upper barrel;
- and
- a stop mechanism for prohibiting said upper barrel from disassociating with said lower barrel.
A compressed air plunger comprising:
- an upper barrel;
- a lower barrel slidably received by said upper barrel;
- a force handle attached to said upper barrel;
- a nozzle engageable with a drain;
- wherein when said force handle is pushed towards said nozzle air pressure is exerted on said drain;
- and
- a seal disk wherein said seal disk comprises a void for receiving said nozzle wherein
- when said force handle is pushed towards said nozzle said seal disk contours to said drain.
The compressed air plunger of claim 13 further comprising a piston cup comprising a central void for receiving said lug wherein said piston cup slidably engages with said upper barrel thereby forming a sliding seal.
A storable apparatus for unclogging a drain comprising:
- an air plunger comprising:
- an upper barrel;
- a lower barrel slidably received by said upper barrel;
- and
- a nozzle engageable with said drain;
- and
- a holder comprising a protrusion which is receivable in said nozzle.
An air plunger comprising:
- an upper barrel;
- a lower barrel slidably received by said upper barrel;
- an air seal between said upper barrel and said lower barrel wherein said upper barrel and
- said lower barrel form a variable volume cylinder;
- a nozzle attached to said lower barrel opposite to said upper barrel;
- wherein when said upper barrel is pushed towards said nozzle said variable volume
- chamber decreases in size and air is expelled through said nozzle from said variable volume chamber.
