Abstract
A tilt-resisting member for a wheeled trash bin is provided. The tilt-limiting member fits a wheeled trash bin having a bottom, a back, a front, and a center of gravity between the back and front. The wheels represent a first fulcrum with a first distance from the center of gravity and provide a pivot point upon which the trash bin can be tilted back. The back edge of the member comprises a second fulcrum that can operably replace the first fulcrum, the second fulcrum having a distance from the center of gravity that is greater than that of the first fulcrum. The increased distance of the second fulcrum from the center of gravity increases the force required to tilt the center of gravity past the second fulcrum.
Claims18
A tilt-resister applicable to a wheeled trash bin comprising:
- an elongate, substantially flat tilt-resisting member, the tilt-resisting member comprising an anchor portion comprising a trash bin axle fixation site;
- and a ground-contacting shelf portion, wherein the tilt-resisting member is configured to be compatible with a wheeled trash bin, the trash bin comprising:
- a bottom wall, a back wall, a front wall, and a center of gravity disposed between the back wall and the front wall, and a set of wheels on an axle positioned proximate a junction of the bottom wall and the back wall, wherein the wheels of the trash bin comprise a first tilting fulcrum at a first distance from the trash bin's center of gravity, and
- wherein the tilt-resisting member, when installed on the trash bin and the trash bin is positioned upright on a ground surface, the ground-contacting shelf comprises a second tilting fulcrum at a second distance from the trash bin's center of gravity that is greater than the first distance from the center of gravity.

A tilt-resistant trash bin comprising:
- a bottom wall, a back wall, a front wall, two side walls, and a center of gravity positioned between the back wall and the front wall, and
- a set of wheels on an axle positioned proximate a junction of the bottom wall and the back wall, wherein the wheels comprise a first tilting fulcrum at a first distance from the center of gravity, and
- at least one tilt-resisting member fixed to the axle of the trash bin, the member comprising
- an anchor portion comprising a trash bin axle fixation site, and a ground-contacting shelf comprising a bottom edge, wherein a distance between the axle-fixation site and the ground-contacting shelf comprises a second distance from the center of gravity, the second distance from the center of gravity being greater than the first distance from the center of gravity.

A method of assembling a tilt-resistant wheeled trash bin comprising:
- providing a wheeled trash bin comprising a bottom wall, a back wall, a front wall, and a center of gravity positioned between the back wall and the front wall, and a set of wheels on an axle positioned proximate a junction of the bottom wall and the back wall, wherein the wheels comprise a first tilting fulcrum at a first distance from the center of gravity;
- providing at least one tilt-resisting member fixable to the axle of the trash bin, the member comprising an anchor portion comprising a trash bin axle fixation site, and a groundcontacting shelf comprising a bottom edge, wherein a distance between the axle-fixation site and the ground-contacting shelf comprises a second distance from the center of gravity, the second distance from the center of gravity being greater than the first distance from the center of gravity;
- and installing the tilt-resisting member on the wheeled trash bin.
A tilt-resistant trash bin comprising:
- a bottom wall, a back wall, a front wall, and a center of gravity positioned between the back wall and the front wall, and a set of wheels on an axle positioned proximate a junction of the bottom wall and the back wall, wherein the wheels of the trash bin comprise a rotatable first tilting fulcrum at a first distance from the trash bin's center of gravity;
- at least one rotatable fulcrum rotational neutralizing mechanism, said mechanism configured to be movable between a position of non-engagement with the rotatable fulcrum that allows the rotatable fulcrum to rotate freely and a position of engagement that disallows rotation of the rotatable fulcrum.
A tilt-resistant trash bin comprising:
- a bottom wall, a back wall, a front wall, and a center of gravity positioned centrally between the back wall and the front wall;
- a set of wheels positioned at a junction of the bottom wall and the back wall, the set of wheels comprising a rotatable first fulcrum positioned at a junction of the bottom wall, said fulcrum being rotatable;
- and
- a non-rotatable second fulcrum extendable rearward from the trash bin, the second fulcrum configured to be reversibly positionable between engagement with a ground surface upon which the trash bin is resting and non-engagement with said ground surface,
- wherein, when the non-rotatable second fulcrum is engaged with the ground surface, the engagement creates sufficient frictional contact with the ground surface that movement of the bin that would otherwise be facilitated by the rotatable first fulcrum is at least impeded.
