In a driver golf head (1) comprising a face (4) having a hitting surface, a sole (3) forming a lower portion, and a crown (5) forming an upper portion, the sole (3) is improved. The sole (3) in the position close to the face (4) was formed into an elastically deformable recess-projection shape, and part of the face (4) was formed into a projecting shape and integrated with the sole (3) to increase rigidity. Using a configuration with increased rigidity and decreased rigidity between the face (4) and sole to obtain an elastically deformable portion and providing a high-rigidity body (12) increased the repulsion force in the lower portion of the face and extended the traveling distance of the golf ball.

A golf club provides carry which does not deteriorate even when a golf ball is struck in a lower position on a face portion. The golf club includes a face portion 4 having a hitting surface, an improved sole portion 3 which forms a lower portion, and a crown portion 5 which forms an upper portion. A deformation portion B which is capable of elastic deformation is provided in concavoconvex form on the sole portion 3 in a position near the face portion 4. This deformation portion B is constituted by a protrusion 10 which is formed such that the sole portion 3 forms an obtuse angle α, and a concave groove 11 which is formed in a direction linking a toe portion and a heel portion by a protrusion protruding towards the crown portion 5.

A bat having a handle portion, a transition portion attached to the handle portion, and a barrel portion attached to the transition portion. The area(s) adjacent to the central portion of the barrel have an increased performance with respect to the central portion of the barrel to effectively enlarge the sweet spot, or preferred hitting area. At least one tubular member of the barrel is circumferential aligned and axially spaced from another tubular member.

A bat for striking a ball comprises an axis, a handle, and a barrel. The handle includes a knob end, an attachment end, and a length separating the knob end from the attachment end. The barrel includes an end cap end, a barrel portion, a barrel length, and a transition section. The transition section is operatively attached to the attachment end of the handle. The bat can include a joint connecting the transition section to the attachment end while separating the barrel from the handle. Further, the bat can include an internal tubular member operatively attached to the end cap end and positioned within the barrel. A knob can be attached to the knob end of the handle while an end cap can be attached to the end cap end of the barrel. A grip can be attached to the handle adjacent the knob.

The invention relates to a golf head alloy with low density and high intensity and a method for making a sheet material of a golf head hitting panel, the golf head alloy comprises the following components by weight: 7-9.5% of aluminium, 0.5-2% of vanadium, 0.05-0.4% of silicon, less than 0.4% of iron, less than 0.15% of oxygen, less than 0.1% of carbon, less than 0.05% of nitrogen and the balance of titanium; and the density of the alloy is 4.32-4.35g / cm<3>; and the invention also provides the sheet material of the golf head hitting panel, so that the sheet material used for producing the golf head hitting panel has lightweighting advantage and better hitting performance.

A training program for improving hitting of a baseball enhancing a batter's tracking skills to a plurality of pitched baseballs. The training program provides a set of baseballs which includes a plurality of patterned baseballs and at least one conventional baseball. Each of the patterned baseballs includes a cover with a perceptible pattern provided thereon, such as a generally elliptical marking conforming to a seam disposed on the cover of the baseball as well as a generally circular marking disposed within the elliptical marking. An instructor or the like detects an audible response from the batter of the color of the pitched baseball as perceived by the batter when the baseball enters the batter's hitting zone.

The invention relates to a method for manufacturing a golf club head. The method comprises the following steps: a hitting panel is prefabricated; a high-energy light beam is utilized to melt a powdery cladding material, and the cladding material is accumulated on the back of the hitting panel in order to form at least a protrusion with a preset shape on the back of the hitting panel. The method can make the hitting panel have good coefficient of restitution (COR) of elasticity, further improve the hitting performance of the golf club head and enlarge a hitting sweet spot; simultaneously, the method can reduce production cost and improve processing efficiency.

There is provided a baseball bat that has performance similar to that of the conventional wooden bat and moreover is excellent in terms of cost and resource conservation. For this baseball bat 11, a reinforcing core 12 having a rectangular cross section is arranged in the center of the cross section thereof continuously so as to penetrate both end thereof, bamboo pieces 24 are laminated around thereinforcing core 12, and an adhesive is caused to permeate into the contact surface between the reinforcing core 12 and the bamboo pieces 24 evenly under a pressure, by which firm bonding can be attained. In addition, by using a material that is hard and has a large specific gravity as compared with bamboo, such as hickory or reinforced wood, as the reinforcing core 12, the flexural rigidity is enhanced as a whole, and the weight is increased. Therefore, the characteristics and feel in use are improved as compared with the conventional bamboo bat, and the baseball bat 11 can be used as a substitute for a wooden bat. Bamboo, hickory, and reinforced wood have no problem in terms of resource conservation, can reduce the product price, and can lower the consumption of scarce resources such asserrata.

The invention provides a boxing target having strong practicability. The construction type of a traditional boxing target is broken through, an elastic layer serves as a direct buffer body for buffering, an upper protruding head utilizes an upper abutting ball to produce relative movement on the lower surface of an upper limiting plate, an upper annular elastic ring conducts comprehensive elasticbuffering in any direction on the upper protruding head, meanwhile a lower protruding head utilizes a lower abutting ball to produce relative movement on the lower surface of a lower limiting plate, alower annular elastic ring executes comprehensive elastic buffering in any direction to the lower protruding head, a whole target body produces translation but not-inclining swing in the boxing process based on keeping the boxing comfort, and convenience is provided for a trainer to continue to perform continuous and comprehensive boxing. In addition, under the joint effect of the upper annular elastic ring and the lower annular elastic ring, the whole target body rapidly restores to an original position, further convenience is provided for the trainer to continue to perform continuous and comprehensive boxing, the horizontal anti-boxing ability of the target body is improved, and the improvement of the boxing effect of the trainer is facilitated.
