ABSTRACT:
A creeper assembly having a first body portion 11 for supporting the hip and lower spine area of a mechanic and a second body portion 25 pivotally connected thereto, via a swivel joint, for supporting the upper spine, shoulder area and head, is disclosed. The swivel joint includes a clevis 36, tongue 19, ball bearing assembly 60 and connecting pin 38. The openings in clevis 36 and ball bearing journal 61 are provided with an inwardly directed key extension 47, 48 received by key slot 39 in connecting pin 38. Fork detent 40 engages stop pin 42 to limit the horizontal, pivotal movement between body portions 11 and 25. Outrigger mounted wheels 17 and 31 permit the use of larger, more durable support wheels. The swivel connection permits quick evasive movement of the head and shoulders by a mechanic, while working, to prevent or minimize injury and discomfort from being struck with dropped tools, dripping oil or dislodged dirt particles.
