Abstract
A convertible sports device has a housing, and sport members movable between an extended and a retracted position relative to the housing. An arresting member is provided, which in a first position abuts against a first face of each of the sport members so as to arrest them in the extended position, and in a second position abuts against another face of the sport members so as to arrest the latter in the retracted position. The housing may be formed as a bottom portion of a shoe or may be attachable to the shoe. The arresting member may be actuated by an actuator which, in turn, may be actuated by a foot of a user so that the sport members may be retracted or extended without the need to use one's hands.
Claims51
In a sports device, a combination comprising
- means forming a housing;
- at least one sport member movable relative to said housing between an extended and a retracted position, and having two faces spaced from one another;
- and
- arresting means including an arresting member movable between a first position in which said arresting member abuts against and is in surface contact with one of said faces of said sport member so as to arrest the latter in said extended position, and a second position in which said arresting member abuts against and is in surface contact with the other face of said sport member so as to arrest the latter in said retracted position.
In a sports device, a combination comprising means forming a housing;
- at least one sport member having three faces and movable relative to said housing between a retracted position and an extended position;
- and arresting means including an arresting member having two faces, said arresting member being movable between a first position in which a first of said faces of said sport member abuts against and is in surface contact with a first of said faces of said arresting member so that sport member is arrested in said retracted position thereof, and a second position in which a second of said faces of said sport member abuts against and is in surface contact with a second of said faces of said arresting member, and a third of said faces of said sport member abuts against and is in surface contact with a portion of said housing so that said sport member is arrested in said extended position thereof.
