摘要:
Golf is waning in popularity partly because of the difficulty of becoming a good player. A key aspect of this difficulty is in using a golf club to drive a ball in a desired direction. To make this easier, the present inventor devised, among other things, a directional golf tee structure that enables players to select a drive direction by orienting the golf tee in the desired direction and then using a golf club to strike a portion of the golf tee instead of the ball. The struck portion of the golf tee filters out or reduces the effect of golf club swing errors, thereby promoting greater accuracy. In some embodiments, the tees are configured for specific loft angles, fade, and/or draw attributes, not only providing a variety of play and training options, but ultimately making golf easier and more enjoyable for players of all skill levels.

A packaging box assembly includes a box including a bottom plate having a first side and a second side, a first plate having a first end portion foldably extending from the first side of the bottom plate and a second end portion, a first cover foldably extending from the second end portion of the first plate and defining a first elongate slot, a second plate having a first end portion foldably extending from the second side of the bottom plate and a second end portion, and a second cover foldably extending from the second end portion of the second plate and defining a second elongate slot aligning with the first elongate slot. A receiving barrel is detachably received in a space defined between the first plate and the second plate, and a suspension ring is pivotally mounted on a top portion of the receiving barrel and extends through the first elongate slot and the second elongate slot.

A cue ball used for practice and play in pool or billiards. The cue ball is made with a plurality of concentric sphere layers or shells starting with a centermost opaque ball, followed by two or three spheres of differently colored semi-transparent polymer resins; then an outermost clear layer of polymer.

A roller mount for a roller of a conveyer has an axle, multiple holding panels, and a fastener. The holding panels are mounted around a connecting end of the axle, and each has a positioning hole and a securing hole. The positioning hole has a diameter larger than that of the connecting end of the axle. At least one pair of male-female combination is defined between each pair of adjacent holding panels. A distance between an uppermost one pair of the at least one male-female combination and the positioning hole in one of a corresponding pair of adjacent holding panels is different that between the uppermost pair of male-female combination and the positioning hole in the other of the pair of adjacent holding panels. The fastener is mounted through the aligning securing holes in the holding panels.

A drive roller controller for accumulating conveyor system has a casing and a circuit board. The casing has a front face, two opposite sides and multiple openings respectively defined on opposite sides. The circuit board is mounted inside the casing and has at least a processor, a first and second communicating ports and an input device. The first and second communicating ports are respectively mounted inside openings on the opposite sides of the casing, so a wire is connected between the first and second communicating ports on opposite sides of the adjacent two drive roller controllers. Therefore, the wire is not easily protruded outside the accumulating conveyor unit, so the connection of wire and the drive roller controller is not easily disconnected.

A bearing assembly with at least one row of balls is disclosed. The bearing assembly has a shaft tube, at least one pair of bearing covers pressed onto the shaft tube, a concave surface formed in facing sides of each of the bearing covers, a row of balls received in the corresponding concave surfaces of the pair of bearing covers and a race arranged on the outer periphery of the row of balls to receive them. The bearing assembly can be arranged with multiple rows of balls to improve the ability to bear a large load between the rotating and stationary members.

A motor brake mechanism includes a base which has a disk and hooks integrally extending from a peripheral edge of the disk to adapt to engage with a top face of the fixing plate. Because the hooks are integrally formed with the disk, the overall structural integrity of the base is enhanced. Thus position of the lining between the induced magnet and the friction disk is securely maintained.

A bearing includes a rotation element, a plastic ring securely mounted on the rotation element and having a U-shaped groove defined in an outer periphery of the plastic ring and a metal ring securely mounted on the outer periphery of the plastic ring and having a second U-shaped groove aligned with the U-shaped groove of the plastic ring. Load capability of the bearing is high due to the addition of the metal ring on the plastic ring and manufacture cost is low because work involved in mounting the plastic ring on the outer portion is elementary.
