Abstract: A collapsible goal frame for ball games has a frame composed by a vertical n-shaped frame, an upper horizontal n-shaped frame, a lower horizontal n-shaped frame and two vertical supporting poles; in particular, connecting tubes are contraposed between the upper horizontal n-shaped frame and the lower horizontal n-shaped frame; the present invention is characterized that two sides of the vertical n-shaped frame are respectively disposed with a 180° bendable joint; on two sides of the upper horizontal n-shaped frame and the lower horizontal n-shaped frame are respectively disposed with a 90° bendable joint; after the supporting pole is detached, the bendable joints of the upper horizontal n-shaped frame and the lower horizontal n-shaped frame are folded toward each other; then the bendable joints on two sides at the center of the vertical n-shaped frame are bent forwardly and downwardly to form a collapsed structure slightly in a W-shape.

Abstract: A cutting mat comprises a cutting mat body and a lock assembly arranged to secure the cutting mat to a rotary anvil. The lock assembly comprises male and female locking members formed at opposite ends of the cutting mat and integral therewith. There are no metal frames or other components welded or otherwise secured to the male or female locking members. The female locking member slips into an axial channel on a rotary anvil. The cutting mat is wrapped around the rotary anvil, and the male member is inserted into the axial channel in locking relationship with the female locking member. Further, the axial edges of the cutting mat are formed in mating, complimentary serpentine shape to prevent a cutting blade from slipping into the seam between adjacent cutting mat surfaces.

Abstract: A golf club grip made up of a composite strip that includes a first segment having a felt layer to the upper surface of which is bonded a polyurethane and a second segment having a felt layer to the upper surface of which is bonded a layer of polyurethane. Depressed decorative indicia are embossed on the upper surface area of the polyurethane layer of the second segment to densify such polyurethane layer. When the strip is spirally wrapped about a resilient underlisting sleeve or directly about the handle of a golf club the embossed indicia increases the hoop strength of the strip reducing the tendency of the strip to unravel.

The rack may include a device that produces a light beam. The rack may also include a diffuser or a photodetector that creates a signal when it receives a light beam. The light beam may be reflected back from an element positioned on the table or may emanate from the table.

Abstract: An adjustable basketball goal system wherein a basketball goal is mounted to a moveable sleeve slidable a post. A ring is attached to the sleeve and connected to a cable. The cable runs through a pulley at the top of the post, then back through the ring and down to a winch. The winch functions to draw in cable thereby raising the sleeve and the attached goal, to release cable and thereby lower the goal, and to hold the cable in position and thereby fix the position of the goal.

Abstract: The present invention provides a multi-piece solid golf ball having excellent rebound characteristics when hitting at low head speed because the rebound characteristics do not depend on the head speed at the time of hitting.

Abstract: A player inputs the first and second instructions utilizing an input device, to move an object toward a target in a virtual field. A power for moving the object is displayed by a graph and a cursor within a range not exceeding the maximum power value. The cursor moves according to lapsed time after the first instruction detection, to make an optical transmission of change in power to the player. When the second instruction is given, the power is determined based on lapsed time from the first instruction detection to the second instruction detection. The object moves based on the determined movement power in the virtual field. When the player inputs change instruction in the maximum movement power value with the use of the input device, the above-mentioned maximum movement power value is changed and the movement power for moving the object is determined within the range, which does not exceed the maximum movement power value as changed.

Abstract: An invention relating to a device and method for training all types of pitchers. The coach observes a pitch, approximating its natural apogee. This point should be at about 12 to 15 feet from the mound/release point. The Pitcher's Box pitcher training system is placed at the approximate point of apogee and adjustments in height and width are made to accommodate the ability of the pitcher, placing the target object as near as possible to the apogee height with the target object being no closer than 12 inches to the top of the enclosed section itself. The coach instructs the pitcher to pitch at and through the target object to the target zone at home plate. The pitcher is able to remove the stigma of distance from the pitch, enabling the subject to work on mechanics, conditioning, strength and repetition. For advanced work by accomplished subjects more than one Pitcher's Box can be used in tandem to establish control and placement, desired movement, and to map movement and reactions.
