Abstract:
An adjustable interchangeable golf club with a faceplate-based platform to receive components for enhancing and controlling various aspects that control the golf ball flight and spin characteristics. Disclosed are components for adjusting loft and bounce angle, and interchangeable faceplate and rear flange styles. Novel milled surface roughness for enhanced spin control is disclosed along with new milling methods for achieving optimal surface roughness. Lightweight hosel and consequent redistribution of mass in club head greatly increases the inertia of the golf club. Centrally located hosel position aids in club head stability on off-center hits. This results in a golf club that hits the ball higher, straighter, longer, and with increased ball spin characteristics.
Abstract:
Die vorliegende Erfindung betrifft ein Ballschlaggerät (1), insbesondere einen Tennis-, Squash- oder Badminton-Schläger, mit einem eine Schlagfläche umfassenden Kopfrahmen (2), der hohl ausgebildet und aus Kunststoff, insbesondere aus einem faserverstärkten Kunststoff hergestellt ist, sowie einem daran angeformten Schaft mit Griff, wobei die Schlagfläche (12) durch mindestens eine über Kreuz gespannte Saite (8) bestimmt ist, welche im Wesentlichen parallel zueinander am Kopfrahmen befestigte Saitenabschnitte bildet, wobei die Verankerung der Saitenabschnitte am Kopfrahmen (2) über Haltebügel (20) erfolgt, die an der Innenseite des Kopfrahmens so befestigt sind, dass sie sich jeweils im Wesentlichen senkrecht zur Schlagfläche erstrecken, wodurch die in den Haltebügeln (20) eingespannten Enden (10) der Saitenabschnitte beim Aufprall eines Balls seitlich auslenkbar sind. Mit dem Ziel, ein derartiges Ballschlaggerät und ein Verfahren zu seiner Herstellung anzugeben, bei dem die Verankerung der Saitenabschnitte am Kopfrahmen über Haltebügel erfolgt, die sich präzise und leicht im Kopfrahmen anordnen lassen und auch für ein Massenherstellungsverfahren geeignet sind, ist vorgesehen, dass die Haltebügel (20) zu einer der beiden Seiten der Schlagfläche (12) hin offen bzw. von einer der beiden Seiten der Schlagfläche (12) her zum Einspannen der die Schlagfläche definierenden Saite frei zugänglich sind.
Abstract:
A golf club head includes a body formed from a metallic material and an insert formed from a polymeric material. The body has a face, a crown, and a sole, and the sole at least partially defines an opening in the body. The insert is configured to be secured to the body across the opening such that the body and the insert cooperate to define a closed volume.
Abstract:
A golf club head includes a face, a crown, a sole, and defines a bore that is configured to receive and to selectively retain an elongate weight. The bore is aligned on a longitudinal axis that intersects the face. An elongate weight is insertable into the bore in either a first orientation or a second orientation, with a first end of the weight making initial entry into the bore when inserted in the first orientation, and a second end of the weight making initial entry into the bore when inserted in the second orientation.
Abstract:
A golf club includes a golf club head having a sole, a crown, and a face. The golf club head defines a bore that has an outer cylindrical portion and a stop extending radially inward from the outer cylindrical portion. An elongate member is insertable within the bore. The elongate member includes a body portion and a protrusion extending radially outward from the body portion. The elongate member is rotatable within the bore between a first angular position and a second angular position, where the elongate member can be freely withdrawn from the bore while in the first angular position and is restrained from being freely withdrawn from the bore while in the second angular position. The stop is at least partially disposed in a path of the protrusion as the elongate member is rotated between the first angular position and the second angular position.
Abstract:
A head for a ball striking device includes a face having a striking surface and a rear side located behind the face, a rear member connected to the rear side of the face member and having a front surface confronting the rear side of the face member, and a resilient material separating the rear member from the face member, such that the resilient member engages the rear member and the face member and is configured to transfer momentum between the face member and the rear member. The face member has projections extending rearwardly from the rear side of the face member proximate the heel and toe sides of the head. The rear member has receivers in the front surface on the heel and toe sides of the head, where the projections are received in the corresponding receivers.
Abstract:
Ball striking devices, such as golf clubs, have a head that includes a face member including a face having a striking surface configured for striking a ball and a rear side located behind the face, a rear member connected to the rear side of the face member, a first connection member connecting the face member to the rear member, and a resilient material separating the rear member from the face member. The first connection member is directly engaged with the rear member, and the club head further includes a first spacer separating the first connection member from the face member. The first spacer is flexible, and the first connection member indirectly engages the face member by compressing the first spacer against the face member. The resilient material engages the rear member and the face member and is configured to transfer momentum between the face member and the rear member.
Abstract:
Some embodiments include a golf ebb head with an arcuate port structure and tuning element. Other embodiments for related golf club heads and methods are also disclosed.
Abstract:
A sports racquet with enhanced string vibration damping has grommets with elongated barrels on many of the cross strings. The internal diameter of the barrels is selected so as to preserve a minimum clearance between the cross string and its enclosing barrel, thereby mitigating vibration. The barrel lengths vary as a function of their distance from the top of the frame, so that their free ends are positioned near the nearest main string.
