Publication number: 20150291268Abstract: A paddle assembly includes a tubular shaft that is configured to be coupled to a blade of the paddle assembly. The shaft has a shaft length, a first flexural rigidity at a first location along the shaft length and a second flexural rigidity at a second location along the shaft length. The ratio of the first flexural rigidity to the second flexural rigidity can be at least approximately 1.20. The shaft is substantially linear along the shaft length. The shaft has a shaft midpoint. The first location and the second location are substantially equidistant from and on opposite sides of the shaft midpoint. The shaft can have a tubular configuration. The shaft has a plurality of layers of material at each of the first location and the second location. The orientation of the layers of material at the first location is different than the orientation of materials at the second location. A modulus of elasticity of the materials used to form the shaft varies along the shaft length.Type: ApplicationFiled: April 10, 2015Publication date: October 15, 2015Inventors: Scott D.

Patent number: 7144335Abstract: A method for manufacturing a golf club head with an insert having a face plate is disclosed herein. The insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The insert preferably has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is preferably disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs.Type: GrantFiled: May 19, 2006Date of Patent: December 5, 2006Assignee: Callaway Golf CompanyInventors: Joshua G.
