Abstract

A toe corrector includes a fastening bracket extending longitudinally, correction bracket extending longitudinally, and rotational adjustment mechanism for adjusting the correction bracket. An adjustable fastening strap for fastening the fastening bracket to a medial side of a foot is disposed on the fastening bracket. An adjustable correction strap for fastening the correction bracket to the medial side of the foot is disposed on the correction bracket. The rotational adjustment mechanism includes an adjustment knob disposed on the fastening bracket and adjustment gear, where a drive gear coaxial with the adjustment knob is disposed at a lower end of the adjustment knob, and is in meshing engagement with the adjustment gear that is connected to the correction bracket, the adjustment knob and the adjustment gear are constructed to enable the fastening bracket to be in articulated joint with the correction bracket that is horizontally rotatable relative to the fastening bracket.

Claims (17)

1 . A toe corrector, comprising: a fastening bracket that extends longitudinally, a correction bracket that extends longitudinally, and a rotational adjustment mechanism configured to adjust the correction bracket, wherein

an adjustable fastening strap that is configured to fasten the fastening bracket to a medial side of a foot is disposed on the fastening bracket;

an adjustable correction strap that is configured to fasten the correction bracket to the medial side of the foot is disposed on the correction bracket; and

the rotational adjustment mechanism comprises an adjustment knob that is disposed on the fastening bracket and an adjustment gear, wherein a drive gear that is coaxial with the adjustment knob is disposed at a lower end of the adjustment knob, the drive gear is in meshing engagement with the adjustment gear, the adjustment gear is connected to the correction bracket, the adjustment knob and the adjustment gear are constructed to enable the fastening bracket to be articulated with the correction bracket, and the correction bracket is horizontally rotatable relative to the fastening bracket;

wherein the rotational adjustment mechanism further comprises a compound gear that is in meshing engagement between the adjustment knob and the adjustment gear, and two gear rings of the compound gear are respectively in meshing engagement with the drive gear and the adjustment gear.

2 . The toe corrector according to claim 1 , wherein a gearbox housing configured to mount the rotational adjustment mechanism is disposed on the fastening bracket; and

two articulated connection arms extending toward the correction bracket are respectively formed on two sides of the gearbox housing, a pivot shaft is disposed at an end of the correction bracket, the pivot shaft is received between the two articulated connection arms, and is articulated with the two articulated connection arms, and the adjustment gear is disposed in the pivot shaft and is coaxial with the pivot shaft.

3 . The toe corrector according to claim 2 , wherein the adjustment knob is axially movably engaged with the gearbox housing, and ratchets that are circumferentially disposed are formed on a lower end surface of the drive gear; and

pawls that correspond to the ratchets are disposed at a bottom of the gearbox housing, and the ratchets are engaged with the pawls to form a ratchet mechanism.

4 . The toe corrector according to claim 3 , wherein the adjustment knob is configured to be movable and pluggable in an axial direction in the gearbox housing; a central shaft extending downward is formed at a lower end of the adjustment knob; a mounting shaft hole for allowing the central shaft to insert is provided in the gearbox housing; and a limiting flange extending inward is formed on an upper edge of the mounting shaft hole; and

a spring contact strip that is elastically connected to the central shaft is formed on the central shaft, and a plug-in stop block and a limiting stop block located at a lower end of the plug-in stop block are formed on an outer surface of the spring contact strip, wherein

upper and lower end surfaces of the plug-in stop block and a lower end surface of the limiting stop block are inclined guide surfaces, and an upper end surface of the limiting stop block is of a vertical surface structure.

5 . The toe corrector according to claim 2 , wherein an arc-shaped travel limiting slot is formed on the articulated connection arm on one side of the gearbox housing, and a travel distance of the travel limiting slot corresponds to an angle-adjustable travel of the correction bracket; and

a limiting post that is embedded into the travel limiting slot is formed on a side end surface of the pivot shaft.

6 . The toe corrector according to claim 1 , wherein the adjustment gear is of a bevel gear structure, and correspondingly, the gear rings that are of the compound gear and that are engaged with the adjustment gear are of a worm transmission structure.

7 . The toe corrector according to claim 1 , wherein non-slip patterns are disposed in a circumferential direction of the adjustment knob; and/or

a gearbox housing configured to mount the rotational adjustment mechanism is disposed on the fastening bracket, and the gearbox housing is longitudinally rotatable relative to the fastening bracket.
