Handle assembly for a curling stone

A curling handle assembly for mounting on a stone body to form a curling stone for use in a sport of curling, the stone body having a cylindrical peripheral surface, a running surface for sliding engagement on a sheet of ice at a bottom side of the stone body, a mounting surface on a top side of the stone body, and a mounting bore extending axially through the stone body between the top side and the bottom side of the stone body to receive a threaded fastener for clamping the handle assembly onto the top side of the stone body, the curling handle assembly comprising:

• a connector arranged to be inserted into the mounting bore at the top side of the stone body for mating connecting with the threaded fastener in a mounted position of the handle assembly;
• a support body extending outwardly from a top end of the connector and defining a lower contact surface for clamping against the mounting surface at the top side of the stone body in the mounted position of the handle assembly;
• a handle body arranged to be gripped in a hand of a user;
• a connector body joined between one end of the handle body and the support body so as to support the handle body in fixed relation to the support body;
• and
• an electronic assembly supported on one or more of the support body and the connector body, the electronic assembly being arranged for measuring at least one performance characteristic relating to use of the curling stone and for communicating the performance characteristic externally to a user;
• the electronic assembly including a sensor circuit, a controller circuit, a battery, and an interrupt switch arranged to selectively interrupt connection of the battery to one or more of the controller circuit and the sensor circuit;
• an interrupt key;
• and
• a key hole communicating through the support body between an interior side of the support body locating the interrupt switch thereon and an exterior side of the support body;
• the key hole being arranged to receive the interrupt key inserted therein in an engaged position of the interrupt key such that the interrupt key engages the interrupt switch and the interrupt switch interrupts the connection between the battery and said one or more of the sensor circuit and the controller circuit in the engaged position of the interrupt key;
• and
• the interrupt key being slidably removable from the support body from the engaged position to a disengaged position of the interrupt key in which the interrupt switch does not interrupt the connection between the battery and said one or more of the controller circuit and the sensor circuit in the disengaged position of the interrupt key.
