ABSTRACT:
The invention is a hitch device for interconnecting two mobile apparatus, such as a hospital gurney and an IV stand. The hitch device comprises a body having first and second ends, each end having a coupling for attachment to a mobile apparatus, and a monoplanarly flexible intermediate portion disposed between the first and second ends. The intermediate portion includes a chain, which is oriented so that only lateral flexing is permitted when the device is in use. The intermediate portion also includes a resilient tube or spring for biasing the intermediate portion to an axial position. A stop located on the first end prevents upward rotation of the intermediate portion beyond a horizontal position when the device is in use.
