A size adjusting mechanism for inline roller skate, the inline roller skate including a plurality of wheels mounted to a lower side of the size adjusting mechanism, and a boot connected to an upper side of the size adjusting mechanism for protecting a user's foot put therein;
- the size adjusting mechanism comprising:
- a boot seat being provided with a mounting recess, which is inwardly extended from a lateral side of the boot seat;
- a toe cap being longitudinally movably connected to a top front of the boot seat;
- a control unit including:
- an engaging element being transversely movably mounted in the boot seat at a predetermined position;
- a control element having an inner part received in the mounting recess and an outer part exposed to an outer side of the boot seat;
- and the inner part of the control element received in the mounting recess having a curved peripheral surface, which is in contact with the engaging element and has a first and a second retaining notch spaced thereon;
- and
- a pivot shaft being eccentrically and rotatably connected to the boot seat and the inner part of the control element, such that a distance between the pivot shaft and the second retaining notch is larger than a distance between the pivot shaft and the first retaining notch;
- and
- an adjusting unit including a first adjusting element provided on a top of the engaging element, and a second adjusting element integrally formed at an underside of the toe cap corresponding to the first adjusting element;
- and the second adjusting element including a plurality of downward projected and longitudinally spaced teeth, which may be selectively engaged with the first adjusting element;
- the control element being rotatable about the pivot shaft between a normal position and a push position when a force is applied to the outer part of the control element, such that the first adjusting element is brought by the control element in the normal and the push position to a lock and a release position, respectively, relative to the second adjusting element;
- the control element in the normal position bringing the engaging element to align with and extend into the first retaining notch, and the first adjusting element to the lock position to engage with the second adjusting element, preventing the toe cap from longitudinally moving relative to the boot seat;
- and
- the control element being turned away from the normal position in a predetermined direction causing the engaging element to detach from the first retaining notch to press against the curved peripheral surface, and finally align and extend into the second retaining notch when the control element is turned to the push position;
- and the control element in the push position pushing the engaging element to move in a direction opposite to the mounting recess, so that the first adjusting element does not interfere with the second adjusting element, allowing the toe cap to be longitudinally moved relative to the boot seat.
