摘要:
An ergonomic handle comprises a handle central body coupled with a shaped portion extending from the central body to the rear of the handle with reference to a running direction, the shaped portion defining a top bearing surface thereon a hand of a user can bear and a bottom handle surface to be gripped by the user fingers, said handle further comprising ventilating means for allowing air to circulate therethrough.

A striking device such as a racquet or tool has a head portion for striking an object and an elongate handgrip with an exterior shell defining an elongate ventilation chamber having a set of air holes for ventilation purposes and to create enhanced gripping ability. An air scoop section is connected to a head end of the shell and forms two air inlets on opposite sides of the handgrip. The air scoop section includes a partition separating the two air inlets, this partition having airflow directing surfaces on opposite sides thereof. These surfaces can direct outside air in a longitudinal direction into the ventilation chamber.

This invention claims new methods to make arm braces that maintain the users' arms straight and fully extended and are also comfortable to wear even in hot weather, by making the braces with nonuniform thickness, their inside surface contoured, and providing them with a plurality of holes penetrating through their inner cushioning liner which are aligned with a plurality of holes penetrating through their outer layer in order to create ventilating channels to allow air to circulate directly between the user's arm and outside the device. Embodiments of the arm braces made by these new methods can be used as golf swing training devices that maintain the golfers' lead arms straight and fully extended and are also comfortable to wear even in hot weather. One embodiment can be described as a clamshell tubular device comprising two partially tubular sections which are hinged lengthwise of the arm and of which at least one section is inflexible lengthwise of the arm, another embodiment can be described as a sheet which is wrapped on the lead arm until it becomes inflexible lengthwise of the arm and another embodiment can be described as a partially tubular device that is inflexible lengthwise of the arm.
摘要:
A friction control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.
摘要:
A golf club having a novel grip the golf club grip includes an underlining sleeve made of rubber. A surface of the underlining sleeve is covered with rubber tapes by spirally wrapping at least two rubber tapes on the underlining sleeve. A lower end of the underlining sleeve is encircled by a fastening member such that the rubber tapes are secured to the underlining sleeve without concerns of falling off. Through characteristics of the rubber tapes as being shock-absorbent, waterproof, anti-slip and abrasion resistant, a golfer is less subject to muscle tissue and arm joint injuries resulted from shock generated by impact between the golf club and a golf ball when hitting the golf ball, and the golf club is also less likely to slip off hands of the golfer.

A golf club grip has a grip tube and a polyurethane band winding the grip tube tightly. The grip tube has a helical groove. The polyurethane band has a large number of vent apertures. An adhesive is applied on the polyurethane band. The golf club grip receives a shaft.
摘要:
A golf club shaft grip having a polyurethane layer bonded to a felt layer. The bonded-together layers are configured as a strip which is spirally wrapped about the shaft. A cap is then telescopically applied over the upper end of the shaft to prevent unraveling of the strip from the shaft.
摘要:
A shock absorbing grip for a golf club having a strip formed of a polyurethane layer bonded to a felt layer, and a resilient sleeve which is applied to a golf club handle. The strip is spirally wrapped about the golf club handle with the side edges being formed with recessed reinforcement side edges which are tightly butted together. The starting end of the strip is skived to provide a smooth configuration of the strip around the upper end of the sleeve.
摘要:
A slip-on grip for a golf club shaft defined by a resilient, cushioned polyurethane and felt strip that is spirally wrapped about a resilient sleeve which is then adhered to the shaft of the golf club. The grip may be substituted for the original grip or, alternatively, may be installed as the original grip on a new golf club shaft.
摘要:
A tennis racquet and grip for the handle of such tennis racquet. The grip has a polyurethane layer bonded to a felt layer. The polyurethane layer is formed with a plurality of dimples, each of which merge into a perforation that extends through the felt layer. The racquet handle is formed with air passages in communication with the dimples and perforations to reduce formation of perspiration on the grip and to enhance the cushioning qualities of the grip.
