Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.

A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.

A golf club head having a cavity therein comprises a wall at least a part of which is formed as a convexo-concave wall portion. The convexo-concave wall portion is composed of convexed portions repeatedly arranged in a first direction and a second direction intersecting the first direction, and concaved portions formed between the convexed portions. Each of the convexed portions includes at least one first protrusion extending in the first direction and at least one second protrusion extending in the second direction.

Methods for fabricating a 3D woven material and exemplary 3D woven material for sporting implements are disclosed. The exemplary weaves can be incorporated into any sporting implements, such as, baseball bats, lacrosse sticks, hockey sticks, rackets, helmets, and other protective equipment. The example sporting implement can be constructed, partially or entirely, with a woven or braided three dimensional structure. The 3D woven material can be a multi-directional layup having tows oriented in three directions (X, Y and Z) and also at any angle created by the combination of two or three directions. A single woven preform can be formed that can have a near net shape of the formed product, with the fibers oriented in a way that will be optimal for the particular application.

A ball throwing device including a lower handle portion, a middle lever portion, and a head portion. The middle lever portion may include a plurality of latitudinal bends positioned between the lower handle portion and the head portion. Additionally and/or alternatively, the head portion may include a half-spherical cup configured to releasably retain a ball, the half-spherical cup having a plurality of edge lobes configured to flex over an outside diameter of the ball.

A golf aide is described for providing tactile feedback to a user during a golf swing. The golf aide has a shaft (12) with a golf grip (11), an arm (14) having a linking element (13) coupling the arm (14) to the shaft (12) at a first end of the arm (14), and a tactile indicator (15) arranged at a distal end of the arm (14) opposite the linking element (13). The tactile indicator has a width greater than a width of the arm and the shaft (12), arm (14) and tactile indicator (15) are fixedly arrangeable such that the distance and angle between a portion of the golf grip to be gripped during a golf stroke and the tactile indicator is equivalent to a predetermined target distance and angle between hands and a lateral upper arm portion of an inside arm of a user at an apex of a backswing of a golf stroke.
