US 4,904,144 A · Truck dumping and unloading apparatus

Abstract

A truck dumping and unloading apparatus which is operated by reverse truck motion and is adapted for mounting on a flatbed truck or a pick-up truck. The apparatus includes a single or double-member, open-top sled having at least a primary compartment adapted for containing trash, garbage or refuse, a sled guide mounted on the back of the truck for receiving a cable, one end of which cable is attached to the sled and a traveling block adapted for traveling on the opposite end of the cable and receiving a pair of tire chains or friction mats for deployment beneath the rear wheels of the truck. Operation of the truck rearwardly and traversal of the tire chains or friction mats by the rear truck tires causes the traveling block to traverse the cable and the sled to slide from the truck bed and dump the trash, garbage, bulk materials or refuse, reponsive to tension applied to the cable by the travelling block.

Dependent claims

A truck dumping and unloading apparatus comprising sled means adapted for carrying refuse, said sled means carried by the bed of the truck;

sled guide means carried by the truck rearwardly of said sled means;
friction means adapted for selective deployment on the truck in non-functional configuration and on the road surface substantially in alignment with the rear wheels of the truck in functional configuration, and connecting means having one end attached to said friction means, said connecting means engaging said sled guide means and the opposite end of said connecting means attached to said sled means, whereby operation of the truck in reverse causes the tires thereof to traverse said friction means, tension said connecting means and displace said sled means rearwardly in the bed of the truck to said sled guide means, for emptying the contents of said sled means.

A truck dumping and unloading apparatus comprising a single member sled having a front bevel and a plurality of rollers engaging the truck bed, said single member sled adapted for carrying refuse;

sled guide means carried by the truck rearwardly of said single member sled, for receiving and tilting said single member sled;
a pair of friction mats adapted for selective deployment on the truck in non-functional configuration and on the road surface substantially in alignment with the rear wheels of the truck in functional configuration;
a flexible cable having one end attached to said sled guide means and the opposite end of said cable means attached to said single member sled;
and a traveling block carried by said cable and said friction mats, whereby operation of the truck in reverse causes the tires thereof to traverse said friction mats and said traveling block to traverse and tension said cable and displace said single member sled rearwardly in the truck to said sled guide means, for emptying the contents of said single member sled responsive to tilting of said front bevel of said single member sled toward the road surface.
