Abstract:
A hockey stick blade comprising a front and a rear blade face, the front blade face comprising at least one front layer of reinforcing fiber material having a first reinforcing fiber density, and the rear blade face comprising at least one rear layer of reinforcing fiber material having a second reinforcing fiber density, the first forcing, fiber density differing from the second reinforcing fiber density. A hockey stick having such a blade is also disclosed.
Abstract:
A field hockey stick including a handle, a throat adjoining the handle, and a head adjoining the throat opposite to the handle. At least one portion of one of the handle, the throat, and the head is hollow. The at least one portion has variable wall thicknesses that enhance the performance and feel of the stick, e.g., providing back weighting and/or edge weighting.
Abstract:
A composite hockey stick having a tubular hollow rectangular shaft and a blade is disclosed. The shaft comprises an inner layer and an outer layer, each of the inner and outer layers are formed of uni-directional substantially continuous fibers disposed in a hardened resin matrix and wrapped and molded around a middle elastomer layer. A new manufacturing method is also disclosed in which a cured hollow tubular composite hockey stick shaft is inserted between the front and back faces of an un-cured composite hockey stick blade and the blade is then cured in a mold around the hockey stick shaft to form a unitary composite hockey stick.
Abstract:
The disclosure relates to a hockey stick comprising a shaft and a blade, the shaft including a top side, a bottom side, a front side, a back side, an upper end, a lower end, and a length extending between the upper end and the lower end, the shaft including a first straight section and a second section. The first section extends from the lower end of the shaft to the second section and the second section extends from the first section to the upper end of the shaft. The second section is disposed at an angle relative to the first section, the angle being defined generally along a plane extending from the top side of the shaft to the bottom side of the shaft, wherein the second section starts at about ½ to about ⅘ of the length of the shaft from the lower end of the shaft.
Abstract:
A sport good, such as hockey stick, Ping-Pong bat, baseball bat, ski stick and so on, has a rigid member made of a composite material. The rigid member has a chamber therein, in which a high-pressure gas is filled to make the sport good having both properties of lighter weight and greater rigidity.
Abstract:
A vibration absorbing material preferably includes a first elastomeric layer of vibration absorbing material which is substantially free of voids therein. A second layer including a hight tensile fibrous material and that is disposed on the first elastomeric layer. The high tensile strength fibrous material distributes vibration to facilitate vibration dampening. A third elastomeric layer is disposed on the second elastomeric layer.
Abstract:
A blade member adapted to be connected to a shaft of a hockey stick or the like includes an elongated hollow blade body, a flexible damping portion, and an interface portion. The elongated hollow blade body defines a receiving cavity, and is made of a fiber reinforced resin composite. The flexible damping portion is disposed within the elongated hollow blade body, and is made of cork. The interface portion is disposed between the elongated hollow blade body and the flexible damping portion.
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:
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 friction control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.
