A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.

Described is a catch and throw folding racket assembly. The racket assembly is formed of a first and second frame member, each having a rotatable handle attached thereto. The frame members are connected with one another with an elastic connected to frame out a catch area. Connected with and between the frame members is a net that is adapted to catch an object within the catch area, such as a ball. In use, a user can catch the ball within the net. When the frame members are pulled apart, the ball is brought out of the frame assembly in a throw motion as the net straightens and is pulled taut to expel the ball.

A sports training device which allows for easy interchanging of weighted inserts. The sports training device includes a body, a handle, a contact zone, a inner chamber, a capping mechanism, and a weighted insert. The weighted insert attaches to the capping mechanism which can be attached the body of the device. The weighted insert is enclosed by the body within the inner chamber. The contact zone of the device can be equipment such as a baseball bat, softball bat, tennis racket, hockey stick, cricket stick, or any equipment used to strike a ball.

Devices systems and methods are disclosed. Among other things, the devices systems and methods can facilitate ergonomic gripping of a handle; conform to the shape of a wrist; enhance golf techniques or performance; enhance racket sport technique or performance; protect a head of a user engaged in contact sports or other hazardous activities; identify concussions, in some cases in substantially real time; provide sterilization of garments; control surgical robots; allow for medical treatment of multiple subjects without disrobing; provide biometric or other data; and/or be used to train muscles or body parts for, for example, performing specified tasks using a body part.

An apparatus including a sensor carried by a racquet and an indicator in communication with the sensor. The sensor outputs a notification based on (a) the number of hits by the racquet based on signals from the sensor and (b) at least one of an elapsed time since a last stringing of the racquet and an input skill level of a person using the racquet. Additionally, an apparatus including a racquet, a sensor carried by the racquet, and an indicator in communication with the sensor. The sensor can be a strain gauge, a load cell, an acoustic sensor and a vibro-acoustic sensor. The sensor outputs a notification based on the number of hits by the racquet based on signals from the sensor.

A somatosensor device comprises a handle (10) having a hollow free end (130) to form a cavity (133) with an opening in a tail end surface (131); a wireless charging circuit board (30) overlapped on the tail end surface (131); a tracker (50) fixed on the wireless charging circuit board (30) and electrically connected with same, the tracker (50) inserted into the cavity (133) as the wireless charging circuit board (30) is overlapped on the tail end surface (131); and an end cap (70) covered on the free end (130) of the handle(10), so as to seal the cavity (133) with the opening in the tail end surface (131). The configuration takes account of the sealability and wireless charging.

A razor accessory that receives a handle of a razor includes a body with a rounded exterior surface and a rectangular channel interior with flat walls to define a rectangular channel from a first end of the body and terminating at a second end of the body and a slit through the body in an axial direction relative to a central axis of the body from the first end of the body toward the second end of the body. The handle of the razor is received by the body with a sliding motion of an end of the handle into the rectangular opening at the first end of the body.
