摘要:
A golf club with a golf club head having non-metallic fasteners is presented. The club head may include a face member, a body member, a sole member and a crown member. The various portions of the club head may be connected using mechanical fasteners, such as screws. In some arrangements, the screws may be formed of a non-metallic material, such as a composite material, in order to reduce weight associated with the club head. In some arrangements, a portion of the mechanical fasteners may be formed of a non-metallic material and may be placed in regions of the club head where reduced weight is desired, while another portion of the fasteners may be formed of metal or other heavier material and may be placed in regions where additional weight may be desired.

Aspects of this disclosure relate to golf club heads which include a wood type golf club head body with a double wall structure that includes a ball striking face portion, which is configured to be disengaged from a rear portion of the golf club head body. Further aspects relate to a second wall portion which is configured to be disengaged from the golf club head body. Golf clubs including these club heads and methods of making such golf club and golf club heads also are provided.
摘要:
A golf club having a golf club shaft and a golf club head is provided. The shaft includes a proximal end, a distal end, and a longitudinal axis extending therebetween. The golf club head, which is attached to the distal end of the golf club shaft, extends from a heel region to a toe region. The golf club head includes an angle adjustment discontinuity that is located below the distal end of the golf club shaft. The angle adjustment discontinuity includes a first elongated groove extending over both a transverse distance and a longitudinal distance. The first elongated groove does not encircle the longitudinal axis.

摘要:
A golf club head system and a golf club head for inclusion into a golf club are provided. The golf club head includes a main body member and a secondary body member. The main body member has a striking surface, a sole portion, a crown portion, and a rear face substantially opposed to the striking surface. The main body member defines an at least substantially enclosed main body cavity. The secondary body member is attached to the main body member and extends at least substantially over the entire rear face of the main body member. The golf club head system includes two or more secondary body members, each configured for interchangeable attachment to a main body member. Each secondary body member defines an internal concavity, has a different external shape, and has a different combination of center-of-gravity and moment-of-inertia characteristics.

The invention provides a toric lens having back surface toric correction that does not result in increased corneal staining. More specifically, the back surface toric optic zone of the lens of the invention is equal to or greater than about 50% of the entire back surface area.
摘要:
Wood-type golf club heads include: (a) a club head body including heel, toe, crown, sole, and weighted rear portions; and (b) a variable thickness ball striking face. The club head body parts and weighted portion(s) may be arranged such that the club head has a moment of inertia about a vertical axis passing through the club head center of gravity of at least 5000 g-cm2. Such club heads may include: (a) a cup face member including a ball striking face portion and a return portion; (b) sole and crown portions engaged with the return portion; (c) a rear body member engaged with the crown and/or sole portions; (d) a weight member at the club head rear; and/or (e) a hosel member engaged with the cup face member, the crown portion, and/or the sole portion.
摘要:
A plasma jet system includes a housing with an opening. A plasma generator is coupled to ionize a fluid in the housing. An electromagnetic accelerator is coupled to generate an electric field that accelerates ionized fluid in the housing toward the opening. A controller can modulate the frequency of the electric field to cause the ionized fluid to form a plasma vortex flow through the opening. A magnetic field is applied normal to the direction of the plasma vortex flow to mitigate the momentum of the electrons. The electrons slowed by the magnetic field can be collected and conducted to a location where they are re-inserted into the plasma vortex flow to maintain charge neutrality.
