Abstract
A racket for use in games such as tennis, badminton, squash paddle ball, etc. having a head and a handle which may be detachably connected to said head at a throat. The head comprises a frame defining a stringing or ball contact area and a throat connected with the frame. The handle has an axially extending rotatable member, such as a threaded bolt. The bolt may extend beyond the handle for attachment to the head. An internally threaded insert is carried by said throat for receiving the bolt so that the handle may be secured to and detached from the head. Guide pins are provided on the handle for engagement with the throat so that the handle will be properly aligned with the head. Grip expanding structure is carried within a partially hollow handle so as to vary the diameter of the handle. The expanding structure includes radially movable wall plates and a rotatable element such as a rod axially carried within the handle. An expander assembly is carried on the rotatable member for applying pressure to the wall plates upon rotation of the rotatable member so as to vary the diameter of the handle.
