DESCRIPTION OF THE PREFERRED EMBODIMENTS
Among other things, the present invention is a slat for a conveyor. Preferred embodiments of the current slat are compatible with a plethora of conveyors, including straight conveyors, curved conveyors as well as conveyors having both straight and curved sections. Preferred embodiments of the current slat can be attached together by any means acceptable in the art to form an endless loop that traverses about the conveyor. Each slat has a first side for carrying articles, a central transverse axis and a second side opposite the first side that is provided with landing gears on opposed sides of the central transverse axis. A wheel is set apart from the second side of the slat and carried by the landing gear such that the wheel is capable of engaging a surface that is distinct from the landing gear.
For many years, the conveyor industry has utilized conveyors with slats to move articles. Most of the prior art slats ride against the slat support and generate frictional resistance. Such friction forces decrease the efficiency of such conveying systems while simultaneously increasing the power consumption and wear and tear of such conveying systems.
Some manufacturers of conveying slats have attempted to reduce frictional resistance by incorporating bearings into the slats. In such prior slat systems, the bearings contact the slat support at angles other than generally normal to the slat. The prior use of these radially located bearings requires the use of oversized bearings and decreases the efficiency of these systems. Because Applicants' landing gear/wheel combination is generally perpendicular to the slat, the current invention can pull greater package loads than the prior systems while the landing gear/wheel combination results in the present invention pulling lesser conveyor loads than prior systems. Through experimentation, the inventors have discovered that integral slat/landing gear/wheel combinations are well suited for the practice of the current invention. By way of example, integral slat/landing gear/wheel combinations have fewer parts to wear out and are easier to assemble and replace.

Roller bearing (110) engages wall (180) and assists endless carrier's (40) movement through a curve of conveyor (30). Preferred embodiments of the structures portrayed in FIG. 8 are generally used for conveyors having one or more curves only in a single direction.

As shown in the preferred embodiment disclosed in FIG. 9, two clevises (lOOf, 100s) carrying roller bearings (1 lOf, 1 10s) are attached to opposed sides of chain (90). Each roller bearing (1 lOf, 110s) engages a wall (180f, 180s) and assists endless carrier's (40) movement through curves of conveyor (30). Preferred embodiments of the structures portrayed in FIG. 9 are generally used for conveyors having curves in more than a single direction.
As shown in the preferred embodiment of FIG. 9, clevises (lOOf, 100s) carrying roller bearings (1 lOf, 110s) are attached to link (90) of chain.
