Abstract
The disclosure features physical activity devices that include (a) a central footrest, configured to receive at least a portion of a foot of a user, (b) a plurality of elongated sleeves, each sleeve having an inner and an outer surface, and being configured to at least partially enclose an elongated tubular support member, and having spaced grooves in its outer surface extending generally perpendicular to a longitudinal axis of the sleeve, and (c) at least two loops extending from the footrest, the loops being configured to be received by the grooves so that the sleeves support the footrest above a surface on which the tubular support members are positioned. The disclosure also features methods of using such devices.
Claims26
A physical activity device comprising:
- a central footrest, configured to receive at least a portion of a foot of a user,
- a plurality of elongated sleeves, each sleeve being open at the top and having an inner and an outer surface, each sleeve being configured to partially enclose an elongated tubular support member, such that the sleeve extends only partially around the circumference of the tubular member and thus is removable from the tubular support member without axial movement of the sleeve, and each sleeve having spaced recessed grooves in its outer surface extending generally perpendicular to a longitudinal axis of the sleeve, and
- at least two elastic cords supporting the footrest, the cords terminating in loops that are received by the grooves when the device is in use so that the sleeves support the footrest above a surface on which the tubular support members are positioned.
A physical activity device comprising:
- a central footrest, configured to receive at least a portion of a foot of a user,
- a plurality of elongated sleeves, each sleeve being open at the top and comprising a linear member having a longitudinal axis that extends parallel to an elongated tubular support member with which the sleeve is in contact during use of the device, and each sleeve having spaced recessed grooves in an outer surface of the sleeve, the grooves extending generally perpendicular to the longitudinal axis of the sleeve, and
- at least two elastic cords supporting the footrest, the cords terminating in loops that are received by the grooves when the device is in use so that the sleeves support the footrest above a surface on which the tubular support members are positioned.
A method comprising:
- attaching a physical activity device having a central footrest to a support structure having three or more vertically extending tubular support members, by (a) placing an elongated sleeve around each of the support members, each elongated sleeve being open at the top and having an inner and an outer surface, and the sleeve being configured to partially enclose the support member and thus be removable from the tubular support member without axial movement of the sleeve, the outer surface of the sleeve including two or more grooves extending generally perpendicular to a longitudinal axis of the sleeve, and (b) placing a loop of an elastic cord that is supported by the footrest around each of the sleeves such that the loop is retained in one of the grooves and the footrest is supported above a surface on which the tubular support members are positioned.
