Abstract: A ball bat includes a barrel having one or more integral features for selectively stiffening regions of the barrel. The barrel may include an indented region forming a rib projecting inwardly into the barrel. Alternatively, one or more inwardly projecting lips may be formed on adjoining barrel sections that are bonded, welded, or otherwise attached to each other, such that an integral, internal rib is formed in the barrel. The internal rib stiffens the barrel, thus reducing the barrel's BBCOR. One or more integral ribs may be provided at any desired barrel locations for selectively limiting the barrel's performance without appreciably increasing the moment of inertia of the ball bat. In another embodiment, a joint, to which two barrel sections are bonded, welded, or otherwise attached, includes an inwardly projecting member that stiffens the barrel, thus reducing the barrel's BBCOR.

Abstract: A ball catching and delivery head including a frame and a base for a lacrosse stick is provided. In addition to a socket for receiving a handle, the base includes a cavity for receiving a flexible cartridge and also trusses laterally located relative to the base that terminally connect with the frame and the base. The frame is vertically flexible relative to the base and the extent to which the frame is so flexible is dependent upon the cartridge flexibility and compressibility. The trusses prevent lateral movements of the frame relative to the base. Different cartridges made of different materials may be substituted for one another to achieve different flexing characteristics.

Abstract: A multi-piece ball bat includes a first section including a hitting portion, and a second section including a handle portion. A flexible joint connects the first section to the second section. The flexible joint may be a structural joint, such as a spring member, a mechanical locking joint, or a pneumatic or hydraulic joint, or it may be a non-uniform and/or non-continuous elastomeric joint.

Abstract: A frame for a ball catching and delivery head for use in, for example, the sport of lacrosse comprising a frame having a scoop, a base and spaced lateral sidewalls therebetween defining the periphery of a ball receiving and delivery face. Each of the lateral sidewalls includes a flex region which is more elastically compliant and resilient than the remainder of the frame. In one embodiment, the flex regions define regions of the sidewalls comprised of a material which is more flexible than the material comprising the remainder of the frame. In another embodiment, the flex regions are defined by springs incorporated into the sidewalls. In a further embodiment, the flex regions are defined by regions of the sidewalls of reduced height and cross-section. In a further embodiment, the sidewalls comprise separate, pivotable aft and fore frame/sidewall members.

Abstract: A head of a lacrosse stick including a frame defining a back stop wall at one end, a scoop wall at an opposite end and side walls therebetween. A plurality of fingers are spaced along the interior face of the back wall and side walls respectively. Each of the fingers protrude outwardly from the interior face of the back wall and side walls respectively and include an outer sloped surface adapted to guide and direct a lacrosse ball into the pocket of the head. Each of the fingers also include a lower sloped shoulder adapted to hold the lacrosse ball in the head and guide and direct the ball between the back wall and the scoop wall. In one embodiment, the length of the fingers increases between the back wall and the side walls to define a pocket for the ball and then decreases along the side walls in the direction of the scoop wall to define a ball ramp.

Abstract: A handle for sports equipment such as a lacrosse or hockey stick including cushioning and grip ribs. In one embodiment, the shaft of the handle defines one or more regions of reduced diameter or thickness such as, in one embodiment, a plurality of elongate longitudinal grooves extending around the periphery thereof in spaced-apart relationship. Interior cushioning ribs are defined in the region of the grooves by a layer of cover or coating material which is applied to the surface of the shaft and fills the grooves. In another embodiment, the shaft includes tapered regions in the shaft and the layer of cover or coating material fills the tapered regions to define cushioning ribs.

In one embodiment, the shaft of the handle defines one or more regions of reduced diameter or thickness including a plurality of elongate longitudinal grooves extending around the periphery thereof in circumferentially spaced-apart relationship. Interior cushioning ribs are defined in the region of the grooves by a layer of cover or coating material which is applied to the surface of the shaft and fills the grooves. In another embodiment, the shaft includes tapered regions in the shaft and the layer of cover or coating material fills the tapered regions to define cushioning ribs.

Abstract: The present invention relates to novel compositions comprising porous materials infused with polymers obtained from metathesis reactions, for example ROMP derived polymers and ADMET derived polymers. The invention further relates to cyclic olefin monomer formulations, including ruthenium or osmium carbene metathesis catalysts, useful for the infusion of porous materials. Also disclosed are methods for preparing the porous materials infused with cyclic olefin resin formulations.

Abstract: The bat of the present invention has a barrel with a thinner outer shell in compressive and/or adhesive engagement with an insert laminate comprised of one or more pieces of a thin metallic (preferably titanium) sheet (or foil) and one or more sheets of a composite material. The titanium portion of the insert laminate may be on the inner-most portion of the insert, may be on the outer-most portion of the laminate, or may be in the interior of the laminate (that is, with one or more sheets of composite material on either side of it). Alternatively, the bat may simply be provided with only a titanium insert. In yet another set of embodiments, the titanium sheet may be replaced by another suitable metallic sheet. In all embodiments, the reinforcing sleeve allows the barrel portion to deflect farther when impacted by an object such as a ball without detrimental yielding (denting) and increases the rate of return of the barrel wall.
