Battery restraint system
First Claim
1. A battery restraint system for securing a battery to a frame structure, comprising:
- first and second spaced apart strap assemblies, each including a flexible non-metallic strap having a first end portion and a second end portion, a bracket secured to each of said first end portions, and said second end portion defining a loop;
a tensioning bar having first and second end portions and a center portion, said first and second end portions being adapted to engage respectively said first and second loops;
first means for securing said brackets to said frame structure;
second means for securing said center portion of said tensioning bar to said frame structure; and
tensioning means for applying a substantially constant downward force on said tensioning bar and said first and second strap assemblies.

Abstract
A battery restraint system for an earthmoving vehicle includes a pair of non-metallic straps with one end of each strap securely fastened to the vehicle frame structure by a bracket. The other end of each strap has a loop which accepts one end of a tensioning bar. A threaded fastener and compression spring connect the center portion of the tensioning bar to the vehicle frame structure and apply a constant and consistent force on the tensioning bar and on the straps. Conventional battery restraints use a metal bracket clamped to the battery by several threaded fasteners. During vehicle operation, the threaded fasteners become loose which allows the battery to move. The fasteners are often difficult to gain access to for re-tightening. The subject battery restraint system maintains a constant force on the battery, and the single threaded fastener is easily accessed.
