Abstract
A trash compactor includes a base member, an elongated stationary support member connected thereto, a mechanism for selectively compressing trash, and a hydraulic mechanism for operably controlling the compressing mechanism. The compressing mechanism includes a plurality of elongated telescopic tubes slidably engageable with each other wherein one of the plurality of tubes has a hollow interior and includes a helical spring member housed therein. The hydraulic mechanism includes a sump and a flexible conduit in fluid communication therewith, a manually operable pump connected upstream of the sump, and a valve connected to the pump for controlling the flow of fluid through the conduit.
Claims9
A trash compactor comprising:
- a base member including a bottom section provided with a substantially planar top surface extending along a horizontal plane and for receiving a trash receptacle thereon, said base member further having a lip portion extending upwardly from the bottom section and being spaced inwardly from a perimeter thereof so that a trash receptacle can be supported at a substantially stable position during operating conditions;
- an elongated stationary support member having integral lower and upper portions, said lower portion being secured to said base member and extending upwardly therefrom, said upper portion extending substantially orthogonally and outwardly from said lower portion and being aligned above said base member;
- means for selectively compressing trash contained within a receptacle wherein said compressing means is connected to said upper portion of said support member and is operable along a substantially vertical plane between extended and retracted positions, said compressing means comprising a plate member formed from durable material and for assisting an operator to compress trash to a desired shape, said compressing means comprising
- a plurality of elongated telescopic tubes slidably engageable with each other and having a common centrally disposed longitudinal axis, one said plurality of tubes having a hollow interior and comprising a helical spring member housed therein, said helical spring member having opposed end portions secured to said support member and said plate member respectively so that said plurality of telescopic tubes are caused to return to a retracted position after being moved downwardly to an extended position, said plurality of tubes having respectively spaced outer surfaces for defining a gap therebetween and selectively receive fluid therein to thereby create a downward force for extending the plurality of tubes:
- hydraulic means connected to said support member and for selectively operating said compressing means, said hydraulic means comprising
- a sump for housing a predetermined volume of fluid,
- a flexible conduit in fluid communication with said sump and extending outwardly therefrom to said compressing means,
- a manually operable pump connected upstream of said sump and bifurcating said conduit so that fluid can be selectively extracted and directed to said compressing means, and
- a handle pivotally connected to said pump and for causing fluid to travel at a selected rate from said sump towards said compressing means.
