Abstract: In accordance with the present invention, a golf putter and method of adjustment of the golf putter are provided. The golf putter includes two threaded connections, one between a weighting element and a putter head, and one between a screw fastener and a replaceable striking surface attachment. The weighting element may be attached to the putter head by manual manipulation. The striking surface attachment may be attached to the putter head by a magnetic connection or any other attachment means suitable for easy replacement during a practice or experimentation mode, and is further configured to be attached to a screw fastener using a tool such that the golf putter is in compliance with rules. The screw fastener passes through the weighting element so that it locks the weighting element simultaneously when affixing the striking surface attachment, thus rendering the weighting element non-removable without the use of a tool.

Abstract: A lacrosse head having at least one of a flexible stringing member and a recessed scoop is provided. In one embodiment, a slot is formed in a head along a stop member, a sidewall, and/or a scoop to provide the flexible stringing member. In another embodiment, the flexible stringing member is a flexible stringing bar that extends from a stop member to a scoop. In another embodiment, the flexible stringing member is more flexible in one direction than another. Through these embodiments, a flexible stringing member can dampen and dynamically narrow the pocket, enhance ball retention, increase pass/shot accuracy, and satisfy pocket-forming preferences. In another embodiment, a scoop has a recess that curves toward a stop member to increase the amount of surface area that contacts a ball when scooping.

Abstract: A multi-component lacrosse stick head, made of at least two materials, including a base lacrosse head structure of one material and one or more overlays made of one or more other materials strategically located on the base structure. The base structure and overlays provide particular performance characteristics for the lacrosse head. An embodiment of the invention includes a base lacrosse head structure, and at least one of a ball stop overlay, a sidewall overlay, an edge overlay, a thread opening overlay, and a scoop overlay. The overlays are affixed to the base lacrosse head structure by, for example, insert molding, over molding, reaction injection molding, spray application, rotational molding, dual extrusion, casting, or an interference fit.

Abstract: An embodiment of the invention provides a sports equipment handle, such as a lacrosse stick handle, that includes a hollow tubular lacrosse stick shaft, a wall of the shaft defining a cavity extending around the shaft in a direction perpendicular to the shaft axis, and a pre-molded latitudinal rib disposed in the cavity, wherein a dimension of the rib is slightly larger than a corresponding dimension of the cavity such that the rib is compressed within the cavity. The shaft can also define a slot substantially parallel to the shaft axis, with a longitudinal rib disposed in the slot. The ribs can be specially located and structured to provide the shaft with structural and tactile features that correspond to and accommodate the way in which a player moves his hands along the shaft and grips the shaft, to enhance the player's control of the shaft when performing various skills.

Abstract: An embodiment of the invention provides a sports equipment handle, such as a lacrosse stick handle, that includes a hollow tubular lacrosse stick shaft defining a slot substantially parallel to the longitudinal axis of the shaft, and a rib disposed in the slot. The shaft and the rib comprise separate structures. In a cross-section of the shaft taken substantially perpendicular to the longitudinal shaft axis, the slot has an opening smaller than a width of the rib such that the rib is retained within the slot. The rib is moveable within and removable from the slot. The rib can be specially located and structured to provide the shaft with structural and tactile features that correspond to and accommodate the way in which a player moves his hands along the shaft and grips the shaft, to enhance the player's control of the shaft when performing various skills.

Abstract: An adjustable customized golf club, e.g., a golf putter, as well as a method for using the club, wherein the club has a head, a striking surface attachment, and one or more lock fittings that positively lock the striking surface attachment to the head. The striking surface attachment is one of several selectable attachments, each with different performance characteristics, e.g., rebound. The one or more lock fittings positively lock the striking surface attachments to the putter head such that the club components are firmly fixed, yet are still quickly removable and replaceable. One embodiment provides a golf club comprising a head defining at least one slot, and a replaceable striking surface attachment having protrusions compressed within the at least one slot.

Abstract: A variable hand placement sports equipment handle, such as a lacrosse stick handle, hockey stick handle, or field hockey stick handle, that includes a shaft and at least one overlay attached to the shaft at a location of frequent hand placement. The overlays are specially located and structured to provide the shaft with structural and tactile features that correspond to and accommodate the way in which a player moves his hands along the shaft and grips the shaft. The structural and tactile features, such as ribs, grooves, and hourglass and conical shapes, are located on the shaft to enhance a player's control of the shaft when performing various skills.

Abstract: A field hockey stick including a throat and a head adjoining the throat, the head having an upper portion adjacent to the throat and a lower portion, and at least the lower portion of the head defining at least one depression. The throat can also define a throat depression.

Abstract: An adjustable customized golf club, e.g., a golf putter, as well as a method for using the club, wherein the club has a head, a striking surface attachment, and one or more lock fittings that positively lock the striking surface attachment to the head. The striking surface attachment is one of several selectable attachments, each with different performance characteristics, e.g., rebound. The one or more lock fittings positively lock the striking surface attachments to the putter head such that the club components are firmly fixed, yet are still quickly removable and replaceable. In a representative embodiment, the striking surface attachment can be removed by hand and without tools. A golfer quickly changes the striking surface attachments without losing the feel of the prior striking surface attachment, thereby enabling the golfer to realistically compare the differences between the attachments before selecting and playing with a particular striking surface attachment.
