According to the invention the ski pole basket comprises a sleeve (4) that is made fixedly attachable to the ski pole shaft by means of a sleeve (4), wherein at least on one open end face of the sleeve a circumferential collar (41) of the sleeve is formed.

Attachment for a pole, in particular for a trekking pole, cross-country ski pole, Nordic-walking pole, or Alpine ski pole, comprising a substantially cylindrical sleeve (3) which can be fastened to the bottom free end (25) of a pole shaft (1), comprising a blind hole (22) open towards the top to accommodate the bottom free end of the pole bar, and an interchangeable clement (2), which can be fastened to the sleeve in a detachable brut-fitting and force-fitting manner. The sleeve comprises a head region (4) and an adjoining body region (5) extending downwards, and an outer thread (6) on at least one axial section of the body region. The interchangeable element comprises a tip or a rolling surface on the bottom end (21) thereof, wherein the interchangeable element has an axial blind hole (15) open towards the top for accommodating the sleeve.

The invention relates to a hand-retaining device (70) for securing to a pole handle (1), comprising an insert opening (71) for the hand, a first exit opening (72) for the back of the hand, and a second exit opening (73) for the thumb. The hand-retaining device according to the invention further has a first elastic strip (74) which is led between the thumb and the other fingers and on which a coupling element (79) is provided that can be secured in or on the pole handle in a removable mechanism in a self-latching manner. The invention further relates to a pole handle to which the handle loop according to the invention can be optimally secured.

A watersports paddle includes an elongated handle body having a first material, a biased member having a second material more flexible than the first material such that the biased member is more flexible than the elongated handle body, and a paddle blade coupled to the biased member opposite the elongated handle body. The biased member deforms when a force is applied to the biased member with the elongated handle body by pulling the paddle blade through water and reforms when the force is not applied to the biased member by the elongated handle body to store and release energy during use of the watersports paddle. The biased member may be a substantially planar leaf spring or a bowed leaf spring.

A plastic composite component which is formed by a thin hard plastic outer layer, at least one elastomer layer adjoining the former on the inside, and at least one metal and/or plastic carrier layer adjoining said elastomer layer on the inside and made of a fibre reinforced plastic (RFP). A carbon fibre reinforced plastic (CRP) or glass fibre reinforced plastic (GRP), is arranged on the component or at least partly forms the latter, as an impact protection part, as a splinter protection part, as a protective part against sudden total failure or as a protective part against vibrations and vibration damages, against resonance, for the purpose of damping oscillations or for the purpose of acoustic damping.

Hollow wall curable and cured composite tubes for improving performance in sports shafts, lightweight applications, and lightweight structural members, are described herein and include: a constituent tube, for forming the hollow wall composite tube, that comprises an evacuable flexible core component on which to wind or braid filaments or fabric, and at least one braid filament or at least one fabric for providing a reinforcing fiber matrix for saturation with an epoxy material, spirally wrapped, applied or braided on the flexible core component. Methods for producing and using the same are also disclosed herein.

Provided are tubular carbon fiber reinforced composite material and having excellent cylindrical bending strength and a golf club shaft using the same. This tubular carbon fiber reinforced composite material is formed by laminating and curing a straight layer and a bias layer. The straight layer comprises carbon fibers S coated with a sizing agent S and arranged in parallel in a direction of 20 to +20 with respect to the axis of the tubular body, and contains a thermosetting resin S. The bias layer comprises carbon fibers B coated with a sizing agent B and arranged in parallel in a direction of +25 to +65 with respect to the axis of the tubular body, and contains a thermosetting resin B. The carbon fiber reinforced composite material constituting the bias layer has an interlaminar shear strength of not less than 110 MPa. A cured product of the thermosetting resin S has an elastic modulus of not less than 4.0 GPa.

A system for measuring power generated by a skier is disclosed. The power generated by the skier may be calculated based upon each complete revolution of a ski pole or ski movement. To do so, the system may include various sensors that measure a force exerted on a ski pole or ski, the angle of the ski pole or ski, and the velocity of the skier at various time instants within each ski pole or ski revolution. A processing unit may calculate power generated by the skier in the skier's direction of travel using the force exerted in the skier's direction of travel during a complete revolution of ski pole (or ski) movement and the velocity of the skier.

Ski pole accessories are described herein. Ski pole accessories can include a releasable ski pole basket system, a ski pole clamp system, and a releasable ski pole strap system. A ski pole basket system can include a ski pole ferrule and a ski pole basket having a slot therethrough that receives and secures the ski pole ferrule. A ski pole clamp system can include a rubber mold with a first and a second thickness to secure the ski pole clamp to an upper component and a lower component of a ski pole. A releasable ski pole strap system can include a pole mount including a jaw that engages a strap attachment member, where operation of the jaw disengages the strap attachment member from the ski pole mount.

A cell phone is attached to a pole not normally used to take photos so that it can be used as a selfie stick. The phone holder is attached to a ski or hiking pole with a pivot and split ring clamp. The phone holder nestles around the pole when skiing or hiking so as not to interfere with that activity. The phone holder is rotated into an open position to attach a phone allowing its use as a selfie stick.
