<p>A device for detachable fastening of a boot (10) to a frame (30) of a roller skate, an ice skate or a snowboard, comprises a first locking mechanism (21, 40) that is mounted in the front part of the boot, and prevents, in its locked state, a relative movement between the boot (10) and the frame (30) in a first direction (A) along the frame and also provides a positive locking with respect to a second direction which is perpendicular to the cross direction of the frame and to the first direction. In the area of the heel (13) of the boot the device comprises a second locking mechanism, that prevents, in its locked state, the relative movement against the first direction (A), and a third locking mechanism (24, 44) that prevents, in its locked state, the relative movement in the second direction (B). The third locking mechanism is provided with a releasing mechanism (60) for unlocking. The respective locking mechanisms each comprise a boot part and a frame part. The boot part of the third locking mechanism (24, 44) comprises a bar-shaped element (24) and its frame part comprises a groove (45) and a locking bar (46), wherein the groove (45) is open to the heel of boot (10), extended essentially in said second direction and accommodates the bar-shaped element (24). The locking bar (46) comprises an upper surface (47) and a lower surface (48). The locking bar is supported so that it is movable between a home position reaching into the groove (45) and a release position retracted at least partially from the groove (45). The locking bar is biased into its home position. The locking bar (46) is arranged in such a way that a force applied by the bar-shaped element (24) to the upper surface (47) of the locking bar (46) in the direction (B) toward the bottom of the groove shifts the locking bar (46) into the release position and allows the bar-shaped element (24) to reach the bottom of the groove, whereupon the locking bar (46) returns toward its home position due to its biasing, and can be moved into the release position only by operating the releasing mechanism (60) engaged therewith.</p> |
