Abstract
A supporting frame for in-line wheels or for an ice-skating blade, including elements for the temporary engagement, centering, and locking of coupling elements which are rigidly coupled below and to the rear of a soft shoe that is adapted for walking. It is thus possible to use, for skating, a shoe used for normal walking.
Claims22
A supporting frame for in-line wheels or for an ice-skating blade, comprising coupling means for being rigidly coupled below and to the rear of a soft shoe that is adapted for walking, and means for the temporary engagement, centering and locking of said coupling means, means for engagement for said shoe being provided which comprise at least one transverse pivot arranged transversely with respect to a pair of shoulders that protrude upwardly with respect to a front base and a flat rear base of said frame, said centering means comprising at least one raised portion which protrudes upwardly and along an axis that runs longitudinally with respect to said flat rear base, said at least one raised portion being arranged on a lower plane with respect to a plane that is parallel thereto and passing through said at least one transverse pivot.
A supporting frame for in-line wheels or for an ice-skating blade, comprising coupling means for being rigidly coupled below and to the rear of a soft shoe that is adapted for walking, and means for the temporary engagement, centering and locking of said coupling means, said means for locking said shoe comprise a lever arm pivoted at a rear end of said frame, said lever arm being U-shaped in cross-section so as to form side wings, which are centrally or eccentrically pivoted at an underlying rear tip of said frame, said side wings of said lever arm having, at a first end, fork-shaped elements.
A supporting frame for in-line wheels or for an ice-skating blade, comprising coupling means for being rigidly coupled below and to the rear of a soft shoe that is adapted for walking, and means for the temporary engagement, centering and locking of said coupling means, said means for locking said shoe comprise a lever arm pivoted at a rear end of said frame, said lever arm being U-shaped in cross-section so as to form side wings, which are centrally or eccentrically pivoted at an underlying rear tip of said frame, a safety hook being transversely pivoted to said side wings, at a second end and in contrast with a flexible element.
A supporting frame for supporting in-line skate wheels or an ice-skating blade and removably attachable to a sole of a sports shoe adapted for walking, the supporting frame comprising:
- a rigid plate element (30) attachable to a bottom of a sole (24) of a sports shoe (20) such that said rigid plate element is accommodated inside a seat (26) in the bottom of the sole and such that said rigid plate does not protrude below a walking surface of the sole for facilitating walking with the sports shoe in a walking mode, said rigid plate element comprising a first engagement element (35) which is accommodated inside the seat in the bottom of the sole when the rigid plate element is attached to the bottom of the sole such that said first engagement element presents an engagement surface facing towards a front end of the sports shoe;
- a frame element (2,3) for supporting in-line skate wheels or an ice-skating blade and being removably attachable with said rigid plate element, said frame element comprising a second engagement element (10) which engages with said engagement surface of said first engagement element when said frame element is attached with said rigid plate element attached to the bottom of the sole such that said second engagement element is arranged between said engagement surface and the front end of said sports shoe;
- and
- a lever element (13) pivotally attached to said frame element and operable for releasably connecting said frame element to a rear portion (41) of the sports shoe above the sole such that said second engagement element releasably locks into engagement with said engagement surface of said first engagement element for rigidly releasably attaching the supporting frame to the sole of the sports shoe.
