Abstract
A container handling apparatus for receiving, engaging and releasing exchangeable chassis mounted containers, which may be truck bodies, or the like, capable of readily locking and unlocking a truck body to a supporting chassis is disclosed that is self-contained on the chassis. A truck body or container which may be self-supporting is also disclosed.
Claims17
A self-contained system for exchanging a detachable refuse hauling truck body detachably secured to and carried by a vehicle chassis, comprising:
- (a) a vehicle chassis having a truck body supporting portion;
- (b) a detachable truck body, said truck body including an independent supporting means comprising a plurality of deployable support leg means attached to said truck body for supporting said truck body as a stand alone unit when said truck body is disconnected from said vehicle chassis, said independent supporting means being deployable and retractable when said truck body is in a raised receive and release position relative to said vehicle chassis;
- (c) dual function truck body handling means including reversible raisable support means on said chassis for raising and lowering said truck body relative to said chassis thereby facilitating the transfer to and from said independent supporting means operable to position said detachable truck body between a raised receive and release position and a lowered, attaching position, and reversible longitudinal positioning means wherein said raiable support means and said reversible longitudinal positioning means include separate and independent motive means for adjusting the position of the truck body along said vehicle chassis to enable reversible securing of said truck body to said chassis;
- (d) truck body attaching means for securing the truck body to the chassis;
- and
- (e) mechanized means on said vehicle chassis for operating said truck body handling means.

- (d) truck body attaching means for securing the truck body to the chassis;
- and
- (e) mechanized means on said vehicle chassis for operating said truck body handling means;
- and
- (f) wherein said attaching means includes at least a first pair of chassis locking means, one associated with each side of said chassis, each capable of interlocking with a corresponding locking means, one associated with each side of a device to be secured to the chassis, said interlocking being reversibly occasioned by the operation of said longitudinal positioning means, said chassis locking means comprising an over-center linkage arrangement.

- (a) a vehicle chassis having a truck body supporting portion;
- (b) a detachable truck body, said truck body including an independent supporting means comprising a plurality of deployable support leg means attached to said truck body for supporting said truck body as a stand alone unit when said truck body is disconnected from said vehicle chassis, said independent supporting means being deployable and retractable when said truck body is in a raised receive and release position relative to said vehicle chassis;
- (c) dual function truck body handling means including reversible raisable support means on said chassis for raising and lowering said truck body relative to said chassis thereby facilitating the transfer to and from said independent supporting means operable to position said detachable truck body between a raised receive and release position and a lowered, attaching position, and reversible longitudinal positioning means for adjusting the position of the truck body along said vehicle chassis to enable reversible securing of said truck body to said chassis;
- (d) truck body attaching means for securing the truck body to the chassis;
- and
- (e) mechanized means on said vehicle chassis for operating said truck body handling means;
- and
- (f) wherein said truck body attaching means comprises a plurality of eccentric cam means, and further comprising a pair of chassis locking means mounted on said vehicle chassis and a pair of truck body locking means, one fixed to either side of said truck body to be secured to the chassis, said pair of chassis locking means being capable of interlocking with said pair of truck body locking means, said interlocking being reversibly occasioned by the rotation of the eccentric cam means.

A self-contained system for exchanging a detachable refuse hauling truck body detachably secured to and carried by a vehicle chassis, comprising:
- (a) a vehicle chassis having a truck body supporting portion;
- (b) a detachable truck body, said truck body including an independent supporting means comprising a plurality of deployable support leg means attached to said truck body for supporting said truck body as a stand alone unit when said truck body is disconnected from said vehicle chassis, said independent supporting means being deployable and retractable when said truck body is in a raised receive and release position relative to said vehicle chassis;
- (c) dual function truck body handling means including reversible raisable support means on said chassis for raising and lowering said truck body relative to said chassis thereby facilitating the transfer to and from said independent supporting means operable to position said detachable truck body between a raised receive and release position and a lowered, attaching position, and reversible longitudinal positioning means for adjusting the position of the truck body along said vehicle chassis to enable reversible securing of said truck body to said chassis;
- (d) truck body attaching means for securing the truck body to the chassis;
- (e) mechanized means on said vehicle chassis for operating said truck body handling means;
- and
- (f) wherein said truck body attaching means comprises a plurality of eccentric cam means and each eccentric cam means further comprises an open slot means positioned so as to be directed in a generally upward direction when said truck body is in the receive and release position for receiving or releasing a latch bar means fixed to said truck body and wherein rotation of each eccentric cam means about an axis of rotation toward a locked position will cause said latch bar means to be engaged and to move in a generally horizontal direction perpendicular to the axis of rotation of said cam means to a position selected from a locked position and one where locking can take place.
