    Abstract: Conventional skipping ropes have a generally elongate handle swivellably mounted on each end of the rope which is held by the user between the fingers and palms. In accordance with the invention, the handle is shaped like a “T” with the vertical stroke of the T being, at one end, swivellably connected to the rope, and also being, at the other end, connected to the crosspiece, a.k.a. transverse portion, of the T. The handle may be held with the crosspiece of the T situated between fingers and palm and with the vertical “stroke”, a.k.a. elongate portion, extending between two fingers. The crosspiece a.k.a. transverse portion of the handle is asymmetric, and thereby adapted to fit to a hand which is holding the handle with the vertical a.k.a. elongate portion passing between two fingers other than the second (index) and third (middle) fingers.

  • Patent number: 7169091
    Abstract: In accordance herewith, a handle of a skipping rope is substantially shaped like a “T” with the vertical stroke or elongate portion of the T at one end, swivellably connected to a rope, and the other end, connected to a crosspiece or transverse portion of the T. The handle may be held in a hand with the crosspiece of the T situated between fingers and palm and with the elongate portion extending between two fingers. The crosspiece or transverse portion of the handle is asymmetric, and adapted to fit to a hand that is holding the handle with the elongate portion passing between two fingers of the hand other than the second (index) and third (middle) fingers. This provides a comfortable and effective skipping position, allowing the crosspiece portion of the handle to be in contact with all the fingers and/or the full width of the palm.
