Embodiments of a co-molded putter-type golf club head comprising a high-density chassis made of a first material and a low-density putter-type body made of a second material. The first material can be a high density metal (i.e., steel or tungsten, but not limited to). The second material can be a low density thermoplastic composite (i.e., polyphenylene sulfide (PPS), polyamide (PA), but not limited to). The chassis comprises a flow aperture, and one or more interlocking features. The putter-type body portion encases the entirety of the at least one interlocking feature. Further, the putter-type body encapsulates the chassis such that the body extends through, and completely fills the flow aperture, to interlock the body and chassis, and thus form the club head. Other embodiments may be described and claimed.

A golf club head includes a front body and a rear body coupled to the front body to define a hollow cavity therebetween. The front body includes a strike face that defines a ball striking surface, a hosel, and a frame that at least partially surrounds the strikeface and extends rearward from a perimeter of the strikeface away from the ball striking surface. The strike face and frame are formed from a thermoplastic composite comprising a thermoplastic polymer having a plurality of discontinuous fibers embedded therein. Each of the plurality of discontinuous fibers have a length of less than about 40 mm. The specific gravity of the thermoplastic can range between 1.0 and 2.0. In some embodiments, the thermoplastic composite is 20% to 70% fibers by volume.

An ice hockey practice target is provided, the target comprising a first substantially tubular portion, including a first end attached to a base and a second end constructed and arranged to engage an upper horizontal goal crossbar, and a second tubular portion attached to the base, the second tubular portion constructed and arranged to engage and secure a lower end of a vertical goal post.

Disclosed is a technical training garment configured for use with modular, interchangeable biomechanics units and or resistance modules. The garment may provide resistance to movement throughout an angular range of motion and or tracks a variety of biomechanical parameters such as stride length, stride rate, angular velocity and power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing or athletic uniform. The device may be worn as a supplemental training and or diagnostic tool during conventional training protocols, or as a biomechanics or biometric data capture device during competition.

A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.

A golf club head comprising a body and a plurality of carbon tubes is disclosed herein. The body comprises a face section, a sole section with a protrusion extending upward and a crown section. The body defines a hollow interior. Each of the plurality of carbon tubes extends from the crown section to the protrusion of the sole section.

The invention relates to a frame for a ball game racket comprising a handle region and a head region with a bridge, wherein a part of the head region and/or the handle region comprise(s) a carbon fiber composite material and wherein the bridge comprises magnesium and is formed as one part.

Golf club heads include white diffusing top surfaces to aid in club head alignment. Wood type club heads also include a dark diffusing club face so that a crown/face border is emphasized. Scorelines in wood type clubs can be provided with an intermediate contrast surface, and can be displaced from club face center to accommodate player perception when confronted with a white diffusing crown. Putter heads can include dark diffusing alignment lines, and iron-type club heads can include white diffusing surfaces at a sole portion of a club face, at a top line, or a top portion of a club face.

Apparatus for football training is provided which includes a circular wall having an inward facing surface to support rebound of a football, which has been struck in a radial direction against this surface, back along said radial direction towards the centre of the circular wall. Multiple target indications are provided at respective angular locations around the circular wall. The apparatus has a control system for activating a series of target indications in sequence, and a monitoring system for determining whether the inward facing surface of the wall has been struck at the angular location corresponding to an activated target indication.

A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.
